Abstract
Benzene, as a major indoor pollutant, has received widespread attention. In order to better control indoor benzene pollution and protect people's health, the limit value of benzene in the"Standards for indoor air quality (GB/T 18883-2022)'' was reduced from 0.11 mg/m3 to 0.03 mg/m3. This study reviewed and discussed the relevant technical contents of the determination of benzene limit value, including the exposure status of benzene, health effects, and derivation of the limit value. It also proposed prospects for the future direction of formulating indoor air benzene standards.

Abstract
Objective: To investigate the effect and regulation of umbilical cord-derived mesenchymal stem cells (UC-MSCs) on islets function and NOD-like receptor family, pyrin domain containing 3 (NLRP3) and autophagy in type 2 diabetic mellitus (T2DM) mice. Methods: Experimental study. Twenty, 8-week-old, male C57BL/6J mice were selected and divided into a normal control group (n=5) and a high-fat feeding modeling group (n=15). The model of T2DM was established by high-fat feeding combined with intraperitoneal injection of low-dose streptozotocin. After successful modeling, those mice were divided into a diabetes group (n=7) and a UC-MSCs treatment group (n=7). The UC-MSCs treatment group was given UC-MSCs (1×106/0.2 ml phosphate buffer solution) by tail vein infusion once a week for a total of 4 weeks; the diabetes group was injected with the same amount of normal saline, and the normal control group was not treated. One week after the treatment, mice underwent intraperitoneal glucose tolerance tests and intraperitoneal insulin tolerance tests, and then the mice were sacrificed to obtain pancreatic tissue to detect the expressions of interleukin-1β (IL-1β) and pancreatic and duodenal homeobox 1 (PDX-1) by immunofluorescence. The bone marrow-derived macrophages were stimulated with lipopolysaccharide and adenosine triphosphate (experimental group) in vitro, then co-cultured with UC-MSCs for 24 h (treatment group). After the culture, enzyme-linked immunosorbent assay was used to detect the secretion level of IL-1β in the supernatant, and immunofluorescence staining was used to detect the expression of NLRP3 inflammasome, and related autophagy proteins. Statistical analysis was performed using unpaired one-way analysis of variance, repeated measure analysis of variance. Results: In vivo experiments showed that compared with the diabetes group, the UC-MSCs treatment group partially repaired islet structure, improved glucose tolerance and insulin sensitivity (all P<0.05), and the expression of PDX-1 increased and IL-1β decreased in islets under confocal microscopy. In vitro experiments showed that compared with the experimental group, the level of IL-1β secreted by macrophages in the treatment group was decreased [(85.9±74.6) pg/ml vs. (883.4±446.2) pg/ml, P=0.001], the expression of NLRP3 inflammasome and autophagy-related protein P62 was decreased, and the expressions of microtubule-associated protein 1 light chain 3β (LC3) and autophagy effector Beclin-1 were increased under confocal microscopy. Conclusions: UC-MSCs can reduce the level of pancreatic inflammation in T2DM mice, preserving pancreatic function. This might be associated with the ability of UC-MSCs to inhibit the activity of NLRP3 inflammasomes in macrophages and enhance autophagy levels.

Abstract
In this study, we evaluated a novel functional monomer (4-formylphenyl acrylate [FA]) that can specifically and covalently bind to the dentin collagen matrix as a potential alternative hydrophobic diluent-like monomer for improving the durability of dentin bonding. Experimental adhesives with different FA contents (0%, 10%, 20%, and 30%) were evaluated as partial substituents for the hydrophilic monomer 2-hydroxyethyl methacrylate, with the commercial adhesive One-Step (Bisco, Inc.) employed as the positive control. Their degree of conversion, viscosity, hydrophobicity, mechanical properties, and water absorption/solubility were measured as the comprehensive characterization. In situ zymographic assays were performed to determine the extent to which FA inhibits the endogenous hydrolytic activity of dentin. Finally, the bonding performances of the novel adhesives were evaluated with microtensile strength tests and scanning electron microscopy. The results showed that the incorporation of FA significantly improved the mobility of experimental adhesives attributable to the dilution property of FA. In contrast to the possible compromised rate of polymerization by hydroxyethyl methacrylate, FA exhibited typical characteristics of favorable copolymerization with polymerizable monomers in adhesives and improved the degree of conversion of experimental adhesives. The rigidity and hydrophobic properties of the phenyl framework of the FA molecule conferred superior mechanical properties and hydrolysis resistance to the novel experimental adhesives. An inhibitory effect on gelatinolytic activities within the hybrid layer was also observed in the in situ zymographic assays, even at a low FA concentration (10%). In conjunction with the significantly improved infiltration found via scanning electron microscopy, the experimental adhesives containing FA possessed significantly better-maintained microtensile strength, even after aging. Thus, the incorporation of this novel monomer endowed the experimental adhesives with multiple enhanced functionalities. These remarkable advantages highlight the suitability of the monomer for further applications in clinical practice.

Background
Hyperkalemia is a common complication and increases the risk of cardiac arrhythmias and mortality in patients with type 2 diabetes (T2DM), especially in those with diabetic nephropathy. We investigated the risk of hyperkalemia in patients initiated on SGLT2 inhibitors versus DPP-4 inhibitors among patients with T2DM.
Methods
This study included patients with T2DM who initiated on SGLT2 inhibitors or DPP-4 inhibitors between January 01, 2015 and December 31, 2019 from a territory-wide clinical registry in Hong Kong (Clinical Data Analysis and Reporting System [CDARS]). A multivariable cox proportional hazards analysis, adjusting for key confounders, was used to compare the risk of central laboratory-determined hyperkalemia (serum potassium ≥6.0mmol/L) and hypokalemia (serum potassium <3.5mmol/L), respectively, between SGLT2 inhibitors and DPP-4 inhibitors.
Results
10193 new users of SGLT2 inhibitors were matched to 17305 new users of DPP-4 inhibitors. During the 2-year follow-up, there were 104 hyperkalemia events (incident rate [IR] = 5.17 per 1000 person-years) among SGLT2 inhibitors and 306 events (IR = 9.09 per 1000 person-years) among DPP-4 inhibitors, of which SGLT2 inhibitors were associated with a lower risk of incident hyperkalemia (Adjusted HR: 0.66 [95%CI 0.53-0.83], p<0.001), compared to DPP-4 inhibitors. The incident hypokalemia was similar between SGLT2 inhibitors and DPP-4 inhibitors (Adjusted HR: 0.91 [95%CI 0.81-1.03], P=0.13).
Conclusion
SGLT2 inhibitors reduced incident hyperkalemia, but without increasing incident hypokalemia compared to DPP-4 inhibitors.

Abstract
Background Circulating thrombospondin-2 (TSP2) levels were associated with the development of heart failure (HF) in recent studies. However, these studies included only a minority of patients with type 2 diabetes, which is associated with an increased HF risk. As hyperglycemia induces TSP2 expression and its tissue expression increases in type 2 diabetes, we investigated the prospective association of circulating TSP2 with incident HF hospitalization (HHF), and its associations with longitudinal changes of echocardiographic parameters in type 2 diabetes. Methods Baseline serum TSP2 levels were measured in 4949 patients with type 2 diabetes to determine its association with incident HHF using multivariable Cox regression analysis. In the echocardiographic study, baseline serum TSP2 levels were measured in another 146 patients with type 2 diabetes but without cardiovascular diseases who underwent detailed transthoracic echocardiography at baseline and after 1 year. Results Over a median follow-up of 7.8 years, 330 of 4949 patients (6.7%) developed incident HHF. Baseline serum TSP2 levels were independently associated with the development of HHF (HR 1.31, 95%CI 1.06–1.62, p = 0.014) after adjustments for baseline conventional cardiovascular risk factors, atrial fibrillation, estimated glomerular filtration rate, albuminuria and high-sensitivity C-reactive protein level, use of angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, loop-diuretics, aspirin, insulin, metformin and sodium-glucose co-transporter 2 inhibitors. Moreover, baseline serum TSP2 levels were independently associated with increase in average E/e’ and left atrial volume index (p = 0.04 and < 0.01, respectively). Conclusion Serum TSP2 levels were independently associated with both incident HHF and deterioration in diastolic function in type 2 diabetes.

Abstract
Abstract
Objective
Severe aortic stenosis (AS) is the primary valvular heart disease, treatable only by aortic valve replacement (AVR). The prognostic value of pre-operative left atrial (LA) function on post-AVR clinical outcomes is uncertain. The study aims to evaluate the prognostic value of pre-operative peak atrial longitudinal strain (PALS) as a surrogate of LA function on post AVR all-cause mortality and heart failure hospitalisation.
Methods
Patients aged 18 years old or above with severe AS were recruited and assessed using speckle-tracking echocardiography pre-operatively. Severe AS was defined according to 2014 AHA/ACC Guideline for the Management of Patients with Valvular Heart Disease. PALS was measured. Based on the median value of PALS, patients were stratified into PALS <15.94% and PALS >15.94%. Patients with underlying pre-operative atrial fibrillation, other moderate to severe valvular heart diseases and cancers were excluded. Patients were followed up until death, heart failure hospitalisation or end of the study. The primary outcome is a composite endpoint of all-cause mortality and heart failure hospitalisation. The association of PALS with the composite endpoint was evaluated by Cox Proportional Hazards analysis.
Results
A total of 128 patients (mean age 65.32±9.42 years, 56.3% male) were prospectively analyzed. Patients were followed up for a mean period of 3.9±2.4 years. A total of 65 of 128 patients (50.8%) belonged to PALS<15.94%. During the study period, 23 patients developed the adverse events. A lower pre-operative PALS, both as a continuous or a categorical variable, were associated with a higher unadjusted risk of adverse events (Continuous; HR, 0.93; 95% CI 0.88–0.98; p=0.011; PALS <15.94%; HR, 4.94; 95% CI, 1.67–14.58; p=0.004).
Conclusion
The study demonstrated a lower pre-operative PALS is associated with all-cause mortality and heart failure admission in patients with severe AS undergoing AVR. Evaluation of LA function by assessing speckle tracking derived PALS may aid in prognostication for patients undergoing AVR.

Addressing pregnancy risks poses as a new challenge among women with repaired tetralogy of Fallot (TOF). The high-output state of pregnancy may predispose women to late complications of repaired TOF. However, guidelines regarding antenatal and or perinatal cardiovascular assessment has not been outlined. Noninvasive modalities such as cardiac magnetic resonance imaging (CMR) that do not require the utilization of ionizing radiation are feasible methods of assessment. Risk stratification of baseline CMR parameters has been sparsely investigated among repaired TOF cohorts. This study aims to identify baseline CMR parameters that may predict adverse outcomes of pregnancy among women with repaired TOF.
Sixty-five successful pregnancies were recorded from a cohort of 105 pregnant episodes. Patients with CMR studies performed within 5 years prior to delivery events were included. Adverse clinical outcomes of interest included arrhythmia, heart failure admissions, gestational hypertension, pre-eclampsia toxemia and all-cause mortality. Baseline CMR parameters regarding ventricular mechanics such as left and right ventricular end-diastolic and end-systolic volumes, left and right ventricular ejection fractions and pulmonary regurgitant fraction were measured, and their association with adverse clinical outcomes were evaluated using an independent-samples t-test.
Within all 65 successful pregnancies, 26 baseline CMR images were obtained and included in this study. The mean maternal age was 29.7 ± 6.7 years old with a mean birth weight of 2.91 ± 0.49 kg at a mean gestational age of 38.4 ± 2.0 weeks. There was a total of 12 patients with adverse clinical outcome: 5 patients with heart failure hospitalizations, 4 patients with gestational hypertension, 4 patients with arrhythmia and 2 patients with pre-eclampsia toxemia.
Assessment of baseline CMR parameters of ventricular mechanics revealed that increased left ventricular end-diastolic volumes (LVEDV) (144.7mL/m2 ± 4.9; P = 0.011), left ventricular end-systolic volumes (LVESV) (65.1mL/m2 ± 9.4; P = 0.004), right ventricular end-diastolic volumes (RVEDV) (235.2 ± 29.0; P = 0.021) and right ventricular end-systolic volumes (RVESV) (122.2mL/m2 ± 38.1; P = 0.033) were associated with an increased incidence of arrhythmia during pregnancy. Nonetheless, there was no significant association between baseline ventricular mechanics with heart failure, gestational hypertension, and pre-eclampsia toxemia.
Baseline assessment of cardiac magnetic resonance imaging among pregnant TOF women revealed that larger left and right ventricular volumes were associated with arrythmia development during pregnancy. Further studies with larger cohort sizes evaluating the role of antenatal and perinatal cardiovascular imaging assessment using CMR in predicting the risks of cardiovascular complications during pregnancy are warranted.

Background
Dementia, in the setting of heart failure (HF), portends poorer outcomes and poses great challenges in its clinical management.
Purpose
We investigated the incidence, types, clinical correlates, and the prognostic impact of dementia in a population-based cohort of patients with HF. Further, we examined the interactions of age and sex, and education status with dementia incidence.
Methods
The previously validated Hong Kong Clinical Data Analysis Reporting System (CDARS), a territory-wide database was interrogated to identify patients with HF (N= 202,121) from 1995 to 2018. Associations of clinical correlates with incident dementia and its risk with all-cause mortality were assessed using competing risk/multivariable Cox regression models where appropriate.
Results
Among a total cohort aged ≥18 years with HF (mean age: 75.3 ± 13.0 years, 51.3% women), new-onset dementia occurred in 22,145 (11.0%) over a median follow-up of 5.5 years. Alzheimer’s disease occurred in 27.0%; vascular dementia (18.1%) and unspecified dementia (in 55.1%). Age-standardized rate of dementia incidence in women was 1297 (95%CI, 1276-1318) (vs. 744, 95%CI, 723-765) per 10000 population in men. Other independent predictors of dementia include: Increasing age (HR 1.08), Female sex (HR 1.19), Nil/< primary (vs tertiary) education (HR 1.29), Parkinson’s disease (HR 1.73), head injury (HR 1.37), peripheral vascular disease (HR 1.31), stroke (HR 1.29), depression (HR 1.18), alcohol intake (HR1.17), anaemia (HR 1.14), hypertension (HR 1.08), among other common comorbidities in HF (Figure 1A).
Notably, a significant interaction (p < 0.001) between age and sex on dementia incidence was observed, such that women in all age groups were observed to have higher sHR compared to men (Figure 1B). After accounting for competing risk, dementia was not associated with adjusted hazard of all-cause mortality.
Conclusions
Female sex, lower socioeconomic status, increasing age and common comorbidities were associated with higher hazards of incident dementia. Abstract Figure 1A and Figure 1B

Following advancements in intracardiac repair of Tetralogy of Fallot (TOF), a greater proportion of patients survive well beyond child-bearing age. Pulmonary regurgitation (PR) and subsequent progressive right ventricular dilatation occur frequently as an intrinsic complication of surgical repair of TOF. High-output states such as pregnancy may exacerbate these late complications. The advocation of pre-pregnancy pulmonary valve replacement to mitigate pregnancy-related cardiac burden has remained controversial. This study aims to delineate the outcomes of pregnancy among women with repaired TOF.
105 pregnant episodes among were identified from a cohort of 240 adult female patients with TOF between 1990 to 2021. Patients with echocardiographic studies performed within 1 year prior to and following delivery were included for cardiac functional analysis. A paired sample t-test was performed to compare echocardiographic parameters between pre-delivery and post-delivery periods. Linear regression was used to identify changes to identify significant changes in echocardiographic parameters among patients with a baseline of severe PR.
Within all pregnant episodes (n = 105), 65 successful pregnancies, 16 spontaneous miscarriages, 21 termination of pregnancies and 3 ectopic pregnancies were recorded. The mean maternal age was 28.9 (±6.7) years with deliveries at 37.86 (30-41) gestational weeks. Cardiovascular events occurred in 19 pregnancies with 4 patients having gestational hypertension, 4 patients with pre-eclampsia toxemia, 7 patients with heart failure symptoms and 4 patients with arrhythmias. Other complications included 4 patients with gestational diabetes mellitus, 3 patients with impaired glucose tolerance, 2 patients with anemia, 3 patients with maternal thyroid disease and 1 patients with proteinuria.
Echocardiographic studies demonstrated significant changes in left ventricular ejection fraction (LVEF) (Pre-delivery = 60.69 ±8.73; post-delivery = 59.39 ±9.36) (P = 0.007), left ventricular end diastolic volume (LVEDV) (Pre-delivery: 89.71mL ±18.22mL; Post-delivery: 80.96mL ±12.32mL; P = 0.007), left end systolic volume (LVESV) (Pre-delivery: 35.43 ±12.36; Post-delivery: 32.70 ± 8.83; P = 3.7x10-5) and right ventricular index of myocardial performance score (Pre-delivery: 0.34 ±0.12; Post-delivery: 0.33 ±0.12; P = 0.007). Patients with severe PR was found to have significantly worse right ventricular global longitudinal strain (RV GLS) (P = 0.029). 2 patients progressed to severe PR following delivery.
Adult female patients with TOF can have viable pregnancies with acceptable mortality and morbidity. Deterioration in echocardiographic parameters were identified when comparing between pre-delivery and post-delivery studies. TOF patients should be closely monitored throughout and post-delivery for detection of deterioration of cardiac function and clinical symptoms.

Abstract
The dentin collagen matrix that is not completely enveloped by resin adhesive is vulnerable to degradation by intrinsic collagenases during the etch-and-rinse process, which contributes to the deterioration of the bonding interface. Current commercial adhesives have no functional components that can form covalent bonds to the dentin collagen matrix. In this study, a photocurable aldehyde, 4-formylphenyl acrylate (FA), was synthesized and for the first time applied as a primer in adhesive dentistry to covalently bind to collagen. Experimental groups with different concentrations of FA (1%, 3%, 5%, 7%, 9%) were prepared as primers. The cytotoxicity was evaluated by live/dead-cell staining and thiazolyl blue tetrazolium bromide assay. The interaction of FA with collagen was examined by attenuated total reflection Fourier transform infrared spectroscopy, hydroxyproline release under the degradation of type I collagenase, and thermogravimetric analysis. An optimal group was selected based on the degree of conversion of 2 universal adhesives and further divided depending on the treatment time (20 s, 30 s, 1 min, 2 min). The bonding performances were evaluated by microtensile strength before and after aging. Finally, the bonding interface was observed under confocal laser scanning microscopy and scanning electron microscope. The results indicated that FA demonstrated good biocompatibility, dentin modification capability, and infiltration. It not only effectively cross-linked dentin collagen to improve its stability against enzymatic hydrolysis and modify the adhesive interface but also potentially acted as a diluting monomer to induce deep penetration of adhesive resin monomers into the dentin. The bonding strength after aging was improved without jeopardizing the degree of conversion of 2 commercial adhesives. Such prominent advantages of using FA to improve the bonding performance promotes its further application in adhesive dentistry.

Abstract
Abstract
Introduction
Multiple valvular heart disease, a combination of stenotic and regurgitant lesions occurring on two or more valves, is a highly prevalent condition. For these patients, surgical correction is the only definitive treatment to improve prognosis, yet concomitant aortic and mitral (double) valve surgery is associated with poor post-operative outcomes. While current guidelines outline left ventricular dimensions and function as surgical triggers, little is known regarding the importance of right ventricular (RV) remodelling in these patients.
Purpose
We sought to evaluate the prognostic value of RV remodelling in patients undergoing double valve surgery.
Methods
RV remodelling was characterised by transthoracic echocardiography in 152 patients undergoing concomitant aortic and mitral valve replacement (n=118) or aortic valve replacement and mitral valve repair (n=34). Four patterns of RV remodelling were defined according to the presence of RV dilation (tricuspid annulus diameter>35mm) and RV systolic dysfunction (percentage RV fractional area change <35%): normal RV size and systolic function (pattern 1); dilated RV with normal systolic function (pattern 2); RV systolic dysfunction with normal RV size (pattern 3); and dilated RV with systolic dysfunction (pattern 4). Adverse events were defined as the composite of all-cause mortality and hospitalisation for heart failure.
Results
Overall, 62 (41%), 31 (20%), 35 (23%), and 24 (16%) patients were classified as RV remodelling patterns 1, 2, 3, and 4, respectively. Patients with advanced RV remodelling patterns were more frequently male, had worse renal function, and a higher EuroSCORE II. During a median follow-up of 43 months, 41 adverse events (22 heart failure hospitalisation and 19 deaths) occurred. Patients with patterns 3 and 4 RV remodelling had an increased risk of adverse events compared to pattern 1 (log-rank χ2 27.42; p<0.001; Figure 1). After adjustments for EuroSCORE II and significant tricuspid regurgitation, RV remodelling patterns 3 (Hazard Ratio [HR] 3.24, 95% Confidence Interval [CI] 1.27–8.24, p=0.014) and 4 (HR 6.18, 95% CI 2.49–15.32, p<0.001) were independently associated with poor post-operative outcomes. Importantly, RV remodelling patterns provided incremental prognostic value to EuroSCORE II (χ2 increased from 18 to 38, p<0.001).
Conclusion
In patients with concomitant aortic and mitral valve disease, RV remodelling is frequent and associated with poorer outcomes. Our study highlights the involvement of the RV in left-sided valvular heart disease and underlines the importance of preoperative assessment of RV geometry and function in patients undergoing double valve surgery.

Abstract
Abstract
Background
The burden of myocardial infarction (MI) with its assorted comorbid complications is increasing parallel to rising life expectancy. Careful characterisation of patient characteristics and identification of short- and long-term complications is critical to their management. Nonetheless, data on the evolving profiles of patient features and outcomes, particularly in an Asian population, remain sparse.
Purpose
We aim to describe the evolving characteristics and outcomes of MI patients in Hong Kong in the past 2 decades.
Methods
From a well-validated territory-wide database in Hong Kong, we included patients with incident acute MI from 1999/01/01 to 2018/12/31. The primary outcome was 30-day all-cause death, while secondary outcomes include haemorrhagic stroke, and pneumonia, at both 30 days and 5 years. Temporal trends in baseline characteristics were evaluated using Poisson regression, while trends in outcomes were evaluated using Cox proportional hazard model, adjusted with demographics, comorbidities, and baseline medications.
Results
A total of 130,218 patients (age 73.6±13.9 years, 40.0% female) were included. Over time, while there was no change in the proportion of females (P=0.196), the increase in mean age (APC 0.23% [0.21 to 0.24], P<0.001) was concordant with the increase in mean CCI (APC 5.1%, [4.8 to 5.3], P<0.001), with more patients suffering from baseline comorbidities (Figure 1; range of APC 1.7% to 4.3%; all P<0.001). The proportion of ST elevation increased significantly (APC 2.5% [2.4 to 2.5], P<0.001).
The adjusted all-cause 30-day mortality rate decreased increased significantly (APC 0.3% [0.1 to 0.5], P=0.005). The increasing trend was significant in older patients (≥70 years), non-ST elevation, and female, while there was a decreasing trend mortality rate in ST elevation and young patients; no significant trend was observed in male. Strikingly, there is an alarming increase in the rate of haemorrhagic stroke (APC 3.4% [2.3 to 4.4], P<0.001) and pneumonia (APC 1.5% [1.3 to 1.7], P<0.001) at 30 days (Figure 2). Although the rate of 5-year all-cause death declined slightly (APC −0.8% [−0.9 to −0.6], P<0.001), there were increasing rates of haemorrhagic stroke (APC 1.0% [0.3 to 1.7], P=0.004) and pneumonia (APC 3.8% [3.6 to 4.1], P<0.001). Patients who were older, had ST elevation, and more comorbid were more likely to develop pneumonia.
Conclusions
Patients with MI have evolved to be older and more comorbid. Alarmingly, despite reduction in long-term all-cause death over time, the reduction was small; risk of death in short-term significantly increased and patients suffer from more complications including haemorrhagic stroke and pneumonia. These results highlight the emergence of extra-cardiac outcomes that drive poor prognosis and accentuate the need to develop tailored strategies to tackle these potentially lethal complications.

Abstract
Abstract
Background
Infective endocarditis (IE) is associated with high mortality and complex microbiological profile. The antibiotic prophylaxis guidelines underwent a major revision in 2009 to reduce unnecessary antibiotic exposure. Substantial geographic variations in microbiological profiles exist, of which the understanding in an Asian population is lacking.
Purpose
We aim to describe the trends in the microbiology of IE in Hong Kong in the past 2 decades.
Methods
All patients aged 20 or above diagnosed with incident IE with blood culture results from 2000–2019 were included from a well-validated territory-wide database in Hong Kong, and were classified as 7 groups of causative organisms as shown in Figure 1. To evaluate the association between microbiology and 1-year all-cause death, a multivariable Cox proportional-hazards model was used, adjusted with demographics and comorbidities. Temporal trends in the proportion of each organism were characterised using Poisson regression. Interrupted time series analysis was used to evaluate the change in the organism-specific incidence after the revision of guidelines.
Results
In a total of 5,657 patients (age 59.9±18.3 years, 37.2% females), there were 2,185 (38.6%) patients with culture-negative endocarditis. Staphylococcus aureus (22.4%) and Streptococci (20.5%) were the most common organisms identified.
Over time, there was a significant reduction in the proportion of culture-negative endocarditis (annual percentage change [APC] −2.3% [−2.8 to −1.7], P<0.001), and a significant increase in the proportion of endocarditis due to Staphylococcus aureus (APC 1.6% [0.7 to 2.4], P<0.001) and Streptococci (APC 2.3% [1.4 to 3.3], P<0.001) (Figure 1). After guidelines revision in 2009, there was no significant change in organism-specific incidence (all P-values for relative change>0.05).
Compared to patients with culture-negative endocarditis, those infected with Staphylococcus aureus (hazard ratio [HR] 2.19 [1.94–2.47], P<0.001), other Staphylococci (HR 1.56 [1.20–2.01], P<0.001), Enterococci (HR 1.60 [1.25–2.05], P<0.001), other microorganisms (HR 1.30 [1.05–1.60], P=0.015), and mixed microorganisms (HR 2.40 [2.02–2.84], P<0.001) had a higher risk of 1-year all-cause death (Figure 2).
There was a significant increase in the proportion of methicillin-resistant Staphylococcus aureus (MRSA) endocarditis (APC 4.1% [1.9 to 6.3], P<0.001), with no significant interval change after 2009. Patients infected with MRSA had a higher all-cause death (HR 2.00 [1.70–2.36], P<0.001).
Conclusions
Different causative organisms carry variable mortality signals in infective endocarditis. Over time, there were fewer cases of culture-negative endocarditis, and the revision of antibiotic prophylaxis guidelines did not result in a significant change in the microbiological profile. There was an increasing trend for MRSA endocarditis, which was associated with a higher risk of death.

Abstract
Abstract
Background/Introduction
Despite improvements in diagnostic and therapeutic strategies, the mortality and morbidity of infective endocarditis (IE) remain high. The incidence, outcomes, and surgical intervention of IE, particularly in an Asian population, are poorly understood and characterised, and the effect of antibiotic prophylaxis guidelines revision on the incidence of IE remains unexplored.
Purpose
We aim to describe temporal changes in the epidemiology and surgical intervention for IE in Hong Kong in the past 2 decades.
Methods
From a well-validated territory-wide database in Hong Kong, all patients aged 20 or above diagnosed with incident IE from 2000–2019 were included. The temporal trends in the incidence of IE, rate of surgical intervention, and mean Charlson Comorbidity Index (CCI) were characterised using Poisson regression analysis and expressed in annual percentage change (APC [95% CI]). Interrupted time series analysis was used to evaluate the change in incidence after the revision of antibiotic prophylaxis guidelines. The association between surgical intervention and mortality was evaluated using propensity score analytics. Temporal trends in 1-year all-cause mortality were evaluated using multivariable Cox regression.
Results
A total of 5,657 patients (59.9±18.3 years, 37.2% females) were included. The crude incidence remained was stable from 2000 to 2019 (APC 0.1% [−0.5 to 0.7], P=0.675), and remained unchanged following the revision of antibiotic prophylaxis guidelines in 2008 (relative risk of change 0.90 [0.64 to 1.00], P=0.065) (Figure 1). Concordant with an increase in the mean age of IE patients (APC 0.9% [0.8 to 1.1], P<0.001), the comorbidity burden grew substantially from 2000 (CCI 0.55±1.27) to 2019 (CCI 1.09±1.66).
The rate of surgical intervention significantly increased from 5.3% in 2000 to 17.8% in 2019 (APC 2.7% [1.1 to 4.3], P=0.004), and surgical intervention at 1 year was associated with a 45% risk reduction in 1-year all-cause mortality (Hazard Ratio 0.55 [0.46 to 0.65], P<0.001). Nevertheless, the crude all-cause mortality rate at 1 year increased from 27.4% in 2000 to 31.5% in 2019, with no significant trend after adjustment for demographics and comorbidities (APC −0.7% [−1.6 to 0.1], P=0.087).
Conclusions
In this large cohort of Asian patients, the incidence of IE remained static and did not change following the revision of antibiotic prophylaxis guidelines. Over time, patients with IE have evolved to be older and more comorbid. Despite an increasing rate of surgical intervention that conferred improved survival, the mortality of IE remained irresistibly high.

Abstract
Abstract
Background
Hepatorenal dysfunction and malnutrition are frequent extracardiac consequences of valvular heart disease (VHD) and have emerged as prominent drivers of adverse prognosis in selected valvular interventions. Nonetheless, data in a general VHD population is sparse, and their interaction and changes following valvular surgery remain unexplored.
Purpose
We aim to characterise the temporal changes, interaction, and prognostic implications of hepatorenal dysfunction and malnutrition before and after valvular surgery.
Methods
Baseline and temporal changes in hepatorenal dysfunction (assessed by the modified model for end-stage liver disease [MELD-XI] score) and nutritional status (assessed by Controlling Nutritional Status [CONUT] score) were correlated with adverse events (composite of all-cause mortality and hospitalisation for heart failure) using Cox proportional hazards model, adjusted with clinical and echocardiographic covariates, medications, type of valvular procedure, and cardiac surgery risk-stratification models (EuroSCORE II and STS score).
Results
Our study included 909 patients who underwent valvular surgery. At baseline, 216 (24%) and 554 (61%) had hepatorenal dysfunction (MELD-XI >12.43) and malnutrition (CONUT ≥2), respectively. MELD-XI scores were modestly correlated with CONUT scores (R=0.36, p<0.001), with concomitant hepatorenal dysfunction and malnutrition present in 177 (19%) patients.
Over a median follow-up of 4.1 years, 101 (11%) patients died and 119 (13%) were hospitalised for heart failure. There was a stepwise increase in mortality (χ2 89.1, p<0.001) and adverse events (χ2 92.9, p<0.001) from patients with normal hepatorenal function and nutrition to concomitant hepatorenal dysfunction and malnutrition (Figure 1). This association remained consistent in fully adjusted models. MELD-XI and CONUT scores significantly improved the discriminatory accuracy of EuroSCORE II (area under the curve [AUC]: 0.80 vs 0.73, p<0.001) and STS score (AUC: 0.79 vs 0.72, p=0.004) for all-cause mortality.
In patients with MELD-XI and CONUT scores 1 year after surgery (n=707), ΔMELD-XI (follow-up MELD-XI minus baseline MELD-XI score) and ΔCONUT scores were significantly associated with adverse events (HR 1.08, 95% CI 1.03–1.14, p=0.001 for ΔMELD-XI; HR 1.18, 95% CI 1.02–1.35, p=0.02 for ΔCONUT). Patients remaining with hepatorenal dysfunction and malnutrition experienced worse survival (log-rank χ2 65.2, p<0.001) and adverse events (log-rank χ2 90.4, p<0.001) (Figure 2).
Conclusions
In patients undergoing valvular surgery, hepatorenal function and nutritional status at baseline, and their temporal changes, are strongly linked to clinical outcomes. These results highlight the role of hepatorenal and nutritional assessment for risk-stratification in valvular surgery.

Abstract
Abstract
Background
Surgery is often indicated in patients with infective endocarditis (IE), but the survival benefits of surgical intervention have not been validated in large-scale studies. Although previous studies appeared to support early surgical intervention, the optimal timing of intervention remains uncertain.
Purpose
We aim to evaluate the benefits of surgery and identify the optimal timing of surgical intervention for patients with IE.
Methods
From a well-validated territory-wide database in Hong Kong, all patients aged 20 or above diagnosed with incident IE from 2000–2019 were included. Patients were divided into those who received surgical intervention within 1 year of IE (surgical cohort) and those who did not (control cohort). The two cohorts were then compared using inverse probability weighting of the covariate balancing propensity score, which included demographics, comorbidities, and causative organism as covariates. Outcomes of interest include, at 1 year, all-cause death, and the development of complications. A Cox proportional hazards model was used to evaluate the association between surgical intervention and death, with “doubly-robust estimation” used to minimise the effect of confounders. For complications, a Fine-Gray model was used to account for competing risk.
The surgical cohort was subdivided into early (≤7 days of hospitalisation) or late surgical intervention; a similar propensity score analytic approach was used to evaluate the effects of early vs. late intervention, with those who died within the 7 days excluded to ensure a fair comparison.
Results
A total of 5,657 patients (age 59.9±18.3 years, 37.2% females) were included, of which 930 (16.4%) received surgical intervention in 1 year. Overall, the surgical cohort had a 45% risk reduction in all-cause death (hazard ratio [HR] 0.55, 95% CI [0.46 to 0.65], P<0.001) (Figure). This association remained consistent in subgroup analysis stratified by age, sex, and causative organisms (Table 1).
The surgical cohort also had a lower risk of complications, including acute kidney injury (HR 0.61, 95% CI 0.43 to 0.87, P=0.006), systemic embolism (HR 0.35 [0.23 to 0.55], P<0.001), ischaemic stroke (HR 0.37 [0.24 to 0.55], P<0.001), cardiac dysrhythmia (HR 0.79 [0.66 to 0.95], P=0.011), and pneumonia (HR 0.36 [0.26 to 0.49], P<0.001).
In the surgical cohort, compared to those who had early surgery (N=181), those with delayed surgery had a lower risk of all-cause death (HR 0.58 [0.34 to 0.99], P=0.045) (Figure) and complications (Table 2) at 1 year. In those who had early surgery, patients who received ultra-early surgery (≤3 days of hospitalisation, N=104) did not have a significantly different risk of death (HR 1.19 [0.47 to 3.34], P=0.654).
Conclusions
Surgical intervention significantly reduced the risk of death and complications in patients with infective endocarditis. Delayed surgical intervention appeared to be more protective.

Abstract
Abstract
Background
There are considerable sex differences in patients with myocardial infarction (MI). However, the recent temporal trends in characteristics and outcomes in women vs. men, particularly in an Asian population, remain poorly understood.
Purpose
We aim to evaluate the sex differences in characteristics and outcomes, and how have these differences evolved over the past 2 decades in patients with MI.
Methods
From a well-validated territory-wide database in Hong Kong, we included patients with incident acute MI from 1999/01/01 to 2018/12/31. Outcomes of interest include, at 30 days, all-cause death, new-onset heart failure (HF), and ischaemic stroke. Trends in sex differences in baseline characteristics were evaluated using linear and Poisson regression, while differences in outcomes were evaluated using Cox proportional hazard model, adjusted with demographics, comorbidities, and baseline medications. A Fine-Gray model was used to evaluate HF and ischaemic stroke to account for competing risk, with all-cause death defined as competing event.
Results
A total of 130,218 patients (age 73.6±13.9 years, 40.0% female) were included. Women were older (79.5±11.7 vs. 69.6±13.8 years, P<0.001) and had a more pronounced increasing trend in age over time (interaction P<0.001). Women were also more comorbid overall (Charlson Comorbidity Index [CCI] 1.25 vs 0.85, age-adjusted P<0.001), but the rising trend in CCI over time was less pronounced than in men (interaction P<0.001) (Figure 1). Women had more baseline hypertension, diabetes, and severe renal disease than men (age-adjusted P<0.001), while the increasing trends in these comorbidities were all more pronounced in men than in women (all interaction P<0.001). Women were more likely to have ST-elevation overall (P<0.001).
Although the crude 30-day mortality rate was higher in women (32.6% vs 23.9%), after adjustment for confounders, they had a lower risk of death (hazard ratio [HR] 0.97, 95% CI [0.96 to 0.99], P=0.003). There was no significant difference in the decreasing trend in 30-day mortality between both sexes (interaction P=0.787) (Figure 1). Women had a higher risk of developing HF (HR 1.04 [1.01 to 1.08], P=0.012) and ischemic stroke (HR 1.36 [1.24 to 1.48], P<0.001) in 30 days.
Among patients aged ≤55 (N=15,324), women (N=2,161, 14.1%) had higher risks of all-cause death (HR 1.61 [1.40 to 1.85], P<0.001), HF (HR 1.64 [1.17 to 2.32], P=0.004), and ischemic stroke (HR 1.69 [1.14 to 2.51], P=0.010) in 30 days, even after adjustment for covariates. The excess mortality in women declined over time (interaction P=0.002).
Conclusions
Women MI patients were older and more comorbid compared to men, which contributed to the higher risk of death, HF, and ischemic stroke among women. Among young MI patients, the increased risk for adverse outcomes among women was particularly pronounced, though the sex differences in mortality reduced over time.

Abstract
Dual inhibition of epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) pathways may delay therapeutic resistance in advanced non-small cell lung cancer (NSCLC). This phase 3 study investigated the efficacy and safety of an erlotinib plus bevacizumab regimen in untreated patients with advanced NSCLC. In total, 311 patients received bevacizumab plus erlotinib (n = 157) or erlotinib only (n = 154). Progression-free survival (PFS) was 17.9 months (95% confidence interval [CI], 15.2-19.9) for bevacizumab plus erlotinib and 11.2 months (95% CI, 9.7-13.8) for erlotinib only (hazard ratio [HR] = 0.55; 95% CI, 0.41-0.73; p < 0.001). A brain metastases subgroup treated with bevacizumab plus erlotinib also showed improved PFS (HR = 0.48; 95% CI, 0.27-0.84; p = 0.008). Grade ≥3 treatment-related adverse events occurred in 86 (54.8%) and 40 (26.1%) patients, respectively. Bevacizumab plus erlotinib significantly improved PFS in patients with untreated metastatic EGFR-mutated NSCLC, including those with brain metastases at baseline.

Abstract
Objective: To investigate the risk factors of moderate or severe perivalvular leakage (PVL) after transcatheter aortic valve replacement (TAVR) with Veneus-A valve. Methods: This study was a single-center case-control study. The clinical data of patients with severe aortic stenosis, who underwent TAVR in the Department of Cardiology of Second Affiliated Hospital of Army Medical University from October 2017 to January 2021, were analyzed. According to the circumferential extent of prosthetic valve paravalvular regurgitation measured by transthoracic echocardiography before discharge (patients who died in hospital were referred to transesophageal echocardiography results after valve implanted), the patients were divided into moderate or severe PVL group and mild or non-PVL group. The clinical features, CT scan and analysis results of aortic root were compared between the two groups. Multivariate logistic regression analysis was used to identify the independent risk factors of postoperative moderate or severe PVL, and receiver operating characteristic (ROC) curve was used to explore the predictive value of related factors. Results: Eighty-two patients (mean age: (70.9±6.5) years, 46 males) were included in the analysis, there were 16 patients in the moderate or severe PVL group and 66 patients in the mild or non-PVL group. The proportion of male gender, depth of valve implantation, size of valve annulus and left ventricular outflow tract (LVOT), and coverage index of LVOT were significantly higher in moderate or severe PVL group than those in mild or non-PVL group (Pall<0.05). As there was a strong collinearity among the valve annular short diameter, LVOT short diameter and LVOT coverage index (partial correlation coefficient R 0.251-0.779, P<0.05), these parameters were not entered in regression model. Multivariate logistic regression analysis showed that valve implantation depth(OR=1.239,95%CI 1.036-1.442,P=0.023), aortic angulation(OR=1.128, 95%CI 1.044-1.312,P=0.038)and LVOT tract coverage index (OR=1.123, 95%CI1.003-1.315, P=0.032) were independent risk factors for moderate or severe PVL after TAVR. The ROC curve showed that the valve implantation depth could predict the occurrence of moderate or severe PVL after TAVR (area under ROC curve (AUC)=0.697, 95%CI 0.554-0.851, P=0.039). Conclusion: Among patients with severe aortic stenosis who undergo TAVR with Venus-A valve, the implantation depth, aortic angulation and LVOT coverage index are independent risk factors of moderate/severe PVL after TAVR, among which valve implantation depth could be used to predict the occurrence of moderate/severe PVL after TAVR.

Abstract
Morphine is an analgesic widely adopted to relieve cancer pain. A number of discrepancies, however, are presented by the published literature, with reports suggesting that opioids may either promote or inhibit the spread of cancer. It is of great significance to determine whether morphine may increase the risk of metastasis while utilized in liver cancer surgical treatment. In this study, we explore the effects of morphine on liver cancer cells in vitro and in vivo. Our results showed that morphine does not promote proliferative ability to cultured liver cancer cells. While morphine could increase the apoptosis rate of Hep3B/HepG2 cells. Furthermore, morphine could significantly inhibit the migratory and invasion ability of Hep3B/HepG2 cells. Subsequent investigations disclosed that morphine could inhibit sphere formation ability of Hep3B/HepG2 cells by using sphere formation assay. Based on nude mouse models, we demonstrated that morphine significantly reduced pulmonary tumorigenicity of Hep3B/HepG2 cells. In conclusion, our results found that morphine at clinical concentrations could suppress liver cancer cell tumor properties in vitro and in vivo, indicating the safety of morphine utilization in HCC patients' pain management.

Abstract
Objective: To investigate the clinical value of carbon nanoparticles zonal tracer technique in lymph node retrieval of gastric cancer (GC). Methods: A retrospective cohort study was carried out. Clinicopathological data of GC patients who underwent radical D2 resection with carbon nanoparticles tracer in The First Affiliated Hospital of Hainan Medical University and Hainan Cancer Hospital from December 2015 and February 2019 were collected. Those with postoperative pathology of T1-2, Borrmann IV type GC, distant metastasis, preoperative neoadjuvant chemotherapy and incomplete data were excluded. A total of 181 patients were enrolled in this study, including 113 cases from the First Affiliated Hospital of Hainan Medical University and 68 cases from Hainan Cancer Hospital. Patients were categorized into two groups based on the methods of carbon nanoparticles tracer: zonal tracer group and traditional tracer group. In the traditional tracer group, 0.1-0.3 ml of carbon nanoparticle was injected subserously at the upper, lower, left and right 4 injection points 0.5 cm away from the edge of the tumor in the normal serous membrane. In the zonal tracer group, on the basis of the traditional tracer group, 0.1-0.3 ml of carbon nanoparticle was injected subserously at the first branch of the suprapyloric right gastric artery into the stomach, the first branch of the subpyloric right gastroepiploic artery into the stomach, the first branch of the minor curvature left gastric artery into the stomach and the first branch of the greater curvature left gastroepiploic artery into the stomach, respectively. The display of lymphatic vessels in each location and lymph nodes in each group by the tracing method was observed. The number of black-stained lymph nodes, the black staining rate of lymph nodes, the total number of detected lymph nodes, the total number of positive lymph nodes, and the metastatic rate of lymph node were compared between the two groups. Results: Eighty-nine patients were assigned to zonal tracer group, and 92 patients to traditional tracer group. There were no significant differences in baseline information between the two groups (all P>0.05). The median number of black-stained lymph nodes (median: 25.0 vs. 13.5, Z=-7.158, P<0.001) and the black staining rate of lymph nodes [(70.8±12.0)% vs. (47.1±15.7)%, t=11.399, P<0.001) in the zonal tracer group were significantly higher than those in the traditional tracer group. The total detected number of lymph nodes (37.5±11.5 vs. 29.6±11.8, t=4.581, P<0.001) and the total number of negative lymph nodes (31.3±12.5 vs. 24.9±11.1, t=3.621, P<0.001) were significantly higher in the zonal tracer group than those in the traditional tracer group. There were no significant differences in the total number of positive lymph nodes (median: 4.0 vs. 3.0, Z=-1.485, P=0.137), lymph node metastatic rate [78.7% (70/89) vs. 72.8% (67/92), χ(2)=0.834, P=0.361] and metastatic degree [median: 11% vs. 10%, Z=-0.483, P=0.629] between the two groups. Conclusion: The carbon nanoparticles zonal tracer method can increase the black-staining rate of lymph nodes and the detected number of lymph nodes, thus improving the accuracy of gastric cancer staging.

Abstract
Objective: To study the clinical application effect of modified nasopharyngeal swab sampling for 2019 novel coronavirus nucleic acid detection. Methods: This study covered the period from January 14 to March 1, 2020.The supine position method and the protective face screen were used to collect nasopharyngeal swabs from February 24 onwards, before which, the nasopharyngeal swabs were collected by sitting position method. All the patients who were diagnosed with suspected/confirmed 2019 novel coronavirus infection were admitted from February 19 with the nasopharyngeal swabs collected outside the hospital before admission. (1) Thirty-four swabbing operators meeting the inclusion criteria of the study were recruited in this retrospective cohort study. They were grouped according to the collection method of nasopharyngeal swabs. Sixteen operators of Wuhan Taikang Tongji Hospital who applied the supine position method and the protective face screen were included in supine position method+ protective face screen group (15 males and 1 female, aged 34-49 years); 18 operators (12 from the First Affiliated Hospital of Army Medical University (the Third Military Medical University), 1 from Wuhan Jiangxia Mobile Cabin Hospital, 5 from the East District of People's Hospital of Wuhan University) who applied the traditional sitting position method were included in sitting position method group (2 males and 16 females, aged 25-49 years). In supine position method+ protective face screen group, when collecting sample, the patient lay flat and wore a special protective face screen for nasopharyngeal swab sampling, with neck slightly extending and face turning to the opposite side of the operator about 10°. The self-designed questionnaire was used to investigate the cooperation, the incidence of nausea, coughing, sneezing, and struggling of patients evaluated by the operators, the operation time for a single swab sample, the fear of operation and the perceived exposure risk of operators in the two groups. (2) Sixty-five patients (22 males and 43 females, aged 25-91 years) admitted to Wuhan Taikang Tongji Hospital who successively received the sitting position method and supine position method+ protective face screen for nasopharyngeal swabs sampling and with complete nucleic acid detection results were included. The positive rates of nucleic acid detection by the two sampling methods of nasopharyngeal swabs of the patients were statistically analyzed. (3) Forty-one patients who could express their feelings accurately were selected out of those 65 patients (12 males and 29 females, aged 27-83 years). The comfort of patients in the process of sampling by the two methods was investigated. (4) Thirty-four patients (10 males and 24 females, aged 25-83 years) with two or more consecutive negative results of nucleic acid detection of nasopharyngeal swabs by sitting position method were selected from the above 65 patients. The positive rate of nucleic acid detection of nasopharyngeal swab of patients by supine position method+ protective face screen, i. e. negative to positive rate was statistically analyzed. Data were statistically analyzed with t test, Wilcoxon signed rank test, and chi-square test. Results: (1) Compared with those of sitting position method group, the cooperation score of patients evaluated by the operators in supine position method+ protective face screen group was significantly higher (Z=-4.928, P<0.01), the incidence of nausea, choking cough, sneezing, and struggling of patients evaluated by the operators, and the fear of operation score and the perceived exposure risk score of operators in supine position method+ protective face screen group were significantly lower (Z=-5.071, -5.046, -4.095, -4.397, -4.174, -5.049, P<0.01), and the operation time for a single swab sample in supine position method+ protective face screen group was significantly longer (t=223.17, P<0.01). (2) The positive rate of nucleic acid detection of nasopharyngeal swabs by supine position method+ protective face screen was 60.00% (39/65), which was obviously higher than 41.54% (27/65) by sitting position method (χ(2)=4.432, P<0.05). (3) The comfort score of the 41 patients during nasopharyngeal swabs sampling by supine position method+ protective face screen was significantly higher than that by sitting position method (Z=-5.319, P<0.01). (4) Of the 34 patients with two or more consecutive negative results of nucleic acid detection of nasopharyngeal swabs by sitting position method, the rate of negative to positive of nucleic acid detection was 26.47% (9/34) after sampling by supine position method+ protective face screen. Conclusions: Compared with the traditional sitting position method, detection of 2019 novel coronavirus nucleic acids of nasopharyngeal swabs collected by supine method combined with protective face screen is worth promoting, because of its better comfort of patients, low exposure risk for operators, in addition to reducing in the false negative result to some extent, which may help reduce false recurrence of discharged patients.

Abstract
Objective: To explore the short-term effects of ambient PM2.5 on the outpatient visits of allergic conjunctivitis among children in Shenzhen. Methods: It was a ecological study. Data on daily visits including date of visit, sex and age from children with allergic conjunctivitis were collected from Shenzhen Eye Hospital and Shenzhen Children's Hospital in 2018. Related data on air pollution (PM2.5, PM10, SO2, NO2, CO and O3) and meteorology (atmospheric pressure, temperature and relative humidity) were also collected. Pearson correlation analysis was used for normal distribution data and Spearman rank correlation analysis was used for non-normal distribution data. Generalized additive model was used to estimate the impact of PM2.5 pollution on allergic conjunctivitis outpatients and the lagging effects. Results: In 2018, there were 16 133 allergic conjunctivitis outpatients in the two hospitals. The maximum age was 18 years and the minimum age was 2 months. Males accounted for 49.3%. The daily average concentration of PM2.5 was 22 (15, 31) μg/m3. Changes of the concentration of PM2.5 had a positive correlation with the amount of allergic conjunctivitis visits, and the Spearman correlation coefficient was 0.150 (P=0.004). The single pollutant model showed that the strongest effect appeared at 3 days (RR=1.111, 95%CI:1.071-1.152). A 10 μg/m3 increase of PM2.5 would result in an excessive number of allergic conjunctivitis outpatients as much as 11.112% (95%CI:7.011%-15.212%). In the multiple air pollutants models, after the introduction of NO2, O3 and CO, the concentration of PM2.5 showed an enhanced effect on the number of hospital visits due to allergic conjunctivitis on the same day, and the difference was statistically significant (P<0.05). Conclusion: Changes of the concentration of PM2.5 had a positive correlation with daily outpatient visits of allergic conjunctivitis among children in Shenzhen.

Abstract
Coronavirus disease 2019 (COVID-19) can cause great damage to the elderly patients and lead to high mortality. The clinical presentations and auxiliary examinations of the elderly patients with COVID-19 are atypical, due to the physiological ageing deterioration and basal pathological state. The treatment strategy for the elderly patients has its own characteristics and treatment protocol should be considered accordingly. To improve the diagnosis, treatment, and prevention of COVID-19 in the elderly, the Expert Committee of Geriatric Respiratory and Critical Care Medicine, China Society of Geriatrics established the "Expert consensus for the diagnosis, treatment, and prevention of Coronavirus disease 2019 in the elderly" . We focused on the clinical characteristics and key points for better treatment and prevention of COVID-19 in the elderly. (1) For diagnosis, atypical clinical presentation of COVID-19 in the elderly should be emphasized, which may be complicated by underlying disease. (2) For treatment, strategy of multiple disciplinary team (mainly the respiratory and critical care medicine) should be adopted and multiple systemic functions should be considered. (3) For prevention, health care model about integrated management of acute and chronic diseases, in and out of hospital should be applied.

Abstract
Objective: To investigate the electrophysiological features of patients with subacute combined degeneration (SCD). Methods: The electrophysiological data of 85 hospitalized patients in Department of Neurology, First Medical Centre, Chinese PLA General Hospital from January 2014 to September 2018 were retrospectively analyzed. Results: Abnormality rate of motor nerve conduction (27.4%(93/339)) was lower than that of sensory nerve conduction (45.9%(107/233)) (P<0.001). Abnormality of sensory nerve action potential amplitude was more frequent than conduction velocity abnormality (22.7%(53/233) vs 4.7%(11/233), P=0.001). Abnormality rate of needle electromyogram (EMG) was higher in lower limbs than upper limbs (31.9%(59/185) vs 5.7%(5/87), P<0.001). Spontaneous potentials were unrelated to disease duration or severity. Abnormal somatosensory evoked potential (SEP) results appeared more frequent in lower limbs (80.8%(118/146)) than upper limbs (61.1%(77/126)) (P<0.001). SEP abnormalities (71.7%(195/272)) were more common than nerve conduction abnormalities (35.0%(200/572)). Abnormal findings presented in 15/16 of visual evoked potential (VEP) studies. Neurological severity score were correlated with electrophysiological findings. Conclusions: Posterior funiculus is more likely to be affected than peripheral nerves in SCD patients. The sensory nerves rather than motor nerves, lower limbs rather than upper limbs, axons of sensory nerves rather than myelin, are more severely affected. Electrophysiological tests can provide evidence in early diagnosis, lesions location, and disease severity evaluation for SCD.

Abstract
Objective: To analyze the relationship of body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR) with diabetes mellitus in community residents aged ≥15 years in Pudong new district of Shanghai, and provide evidence for the prevention and treatment of diabetes mellitus. Methods: Using multi-stage stratified cluster sampling method, a total of 7 194 community residents aged ≥15 years were surveyed by using questionnaire, physical examination and laboratory tests in 2016. The relationship of BMI, waist circumference and waist-hip ratio with diabetes mellitus was analyzed by χ(2) test, single factor linear correlation and logistic regression analyses. Results: In 2016, the crude prevalence rate of diabetes mellitus in Pudong was 27.37%, which was 12.75% after standardization. The prevalence rate of diabetes mellitus was slightly higher in men than in women and was increased with age. The levels of FPG, 2 h plasma glucose and HbA1c were positively correlated with BMI, WC and WHR. After adjusting the confounding factors, multiple logistic regression analysis showed that obesity (OR=1.351, P<0.01), excessive waist circumference (OR=1.255, P<0.01) and high WHR (OR=1.291, P<0.01) were risk factors for diabetes mellitus. Conclusions: The increase of obesity, WC and WHR will increase the risk for diabetes mellitus. It is important to maintain healthy weight, especially the control of WC and WHR, reduce the accumulation of abdominal fat to reduce the risk for diabetes mellitus.

Abstract
PURPOSE Neoadjuvant CT-P6, a trastuzumab biosimilar, demonstrated equivalent efficacy to reference trastuzumab in a phase 3 trial of HER2-positive early-stage breast cancer (EBC) (NCT02162667). We report post hoc analyses evaluating pathological complete response (pCR) and breast pCR alongside additional efficacy and safety measures. METHODS Following neoadjuvant treatment and surgery, patients received adjuvant CT-P6 or trastuzumab (6 mg/kg) every 3 weeks for ≤ 1 year. RESULTS In total, 271 and 278 patients received CT-P6 and trastuzumab, respectively. pCR and breast pCR rates were comparable between treatment groups regardless of age, region, or clinical stage. Overall, 47.6% (CT-P6) and 52.2% (trastuzumab) of patients experienced study drug-related treatment-emergent adverse events (TEAEs), including 17 patients reporting heart failure (CT-P6: 10; trastuzumab: 7). Two CT-P6 and three trastuzumab patients discontinued adjuvant treatment due to TEAEs. CONCLUSION Adjuvant CT-P6 demonstrated comparable efficacy and safety to trastuzumab at 1 year in patients with HER2-positive EBC, supporting CT-P6 and trastuzumab comparability.

Abstract
Objective: To evaluate the efficacy and safety of catheter-directed interventional therapy in patients with acute pulmonary embolism(PE). Methods: PE was diagnosed by CT pulmonary angiography(CTPA). After risk stratification, a total of 79 PE patients (age (58.9±14.9) years old)were treated with catheter-directed interventional therapy via pulmonary vessels. The changes of pulmonary hemodynamics were compared before and after treatment. The risk of complications and side effects were observed. Results: The pulmonary artery pressure was changed followed by interventional therapy. The interventional therapy significantly decreased mean pulmonary arterial pressure (mPAP) from (35.3±11.2)mmHg (1 mmHg=0.133 kPa) to (30.0±10.6)mmHg (t=8.803,P<0.05) and the echocardiographic derived right ventricular dimension to left ventricular dimension (RV/LV) ratio from 0.93±0.16 to 0.83±0.15 (t=6.868,P<0.05). The arterial partial pressure of oxygen was increased from (69.0±8.6)mmHg to (75.1±9.9)mmHg (t=8.561,P<0.05) . The oxygen saturation was also increased from (93.9±2.9)% to (95.1±1.9)% at 24 h after the treatment (t=2.621,P<0.05) . Patients were further grouped as high-risk group (n=28) and intermediate risk group (n=51). mPAP and RV/LV ratio were significantly reduced in the two subgroups (all P<0.05) and the range of reduction was more significant in the high-risk group. Five patients experienced minor bleeding complication, 3 patients suffered worsened dispone post procedure and were treated with mechanical ventilation, 1 patient died, and 1 patient developed recurrent PE. Conclusion: The catheter-directed interventional therapy improves pulmonary hemodynamics and reduces load of right ventricle both in high-risk or intermediate risk PE patients, this therapy strategy is safe and effective for patients with PE.

Abstract
Iguratimod is known for its anti-inflammatory activities and therapeutic effects in patients with rheumatoid arthritis. It has previously been demonstrated that iguratimod attenuates bone destruction and osteoclast formation in the Walker 256 rat mammary gland carcinoma cell-induced bone cancer pain model. Therefore, it was hypothesized that iguratimod may additionally exhibit therapeutic effects on benign osteoclast-associated diseases including postmenopausal osteoporosis. In the present study, ovariectomized mice were used to investigate the effects of iguratimod in vivo. Bone marrow mononuclear cells were cultured to detect the effects of iguratimod on receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclastogenesis in vitro and the molecular mechanisms involved. It was demonstrated that iguratimod may prevent ovariectomy-induced bone loss by suppressing osteoclast activity in vivo. Consistently, iguratimod may inhibit RANKL-induced osteoclastogenesis and bone resorption in primary bone marrow mononuclear cells. At the molecular level, peroxisome proliferator-activated receptor-γ (PPAR-γ)/c-Fos pathway, which is essential in RANKL-induced osteoclast differentiation, was suppressed by iguratimod. Subsequently, iguratimod decreased the expression of nuclear factor of activated T cells c1 and downstream osteoclast marker genes. The results of the present study demonstrated that iguratimod may inhibit ovariectomy-induced bone loss and osteoclastogenesis by modulating RANKL signaling. Therefore, iguratimod may act as a novel therapeutic to prevent postmenopausal osteoporosis.

Abstract
The bone is one of the most common sites of metastasis in patients with cancer. Current treatments for bone metastases include bisphosphonates, denosumab, non-steroidal anti-inflammatory drugs and analgesics, but each of them has certain limitations. Cytokines and mediators released from various cells in the bone microenvironment may drive a vicious cycle of osteolytic bone metastases. Iguratimod (T-614), a novel disease-modifying anti-rheumatic drug, has demonstrated therapeutic effects by suppressing the production of inflammatory cytokines in rats and patients with rheumatoid arthritis. Therefore, the current study evaluated the hypothesis that iguratimod may protect against cancer-induced bone pain and bone metastasis in a rat model. For this purpose, rats inoculated with Walker 256 cells were treated with iguratimod from days 11–17 post-surgery. Mechanical paw withdrawal thresholds and expression levels of phosphorylated extracellular signal-related kinase (pERK) and c-Fos in the spinal cord were investigated to detect changes in bone pain. Bone destruction levels were detected using X-rays, hematoxylin and eosin and tartrate-resistant acid phosphatase staining. The results revealed that mechanical paw withdrawal thresholds and the expression levels of pERK and c-Fos declined in a dose-dependent manner in rats treated with iguratimod, and bone destruction severity was also reduced. These findings may provide important new insights into the treatment of bone metastasis symptoms.

Abstract
The diagnosis and treatment of lung cancer have evolved into the era of precision medicine. Liquid biopsy, a minimally invasive approach, has emerged as a promising practice in genetic profiling and monitoring of lung cancer. Translating liquid biopsy from bench to bedside has encountered various challenges, including technique selection, protocol standardisation, data analysis and cost management. Regarding these challenges, the 2016 Chinese Lung Cancer Summit expert panel organised a trilateral forum involving oncologists, clinicians, clinical researchers, and industrial expertise on the 13th Chinese Lung Cancer Summit to formally discuss these controversies. Six consensuses were reached to guide the use of liquid biopsy and perform precision medicine in both clinic and research.

Abstract
Objective: To assess the association between the concentration of the air pollutant PM2.5 and daily outpatient visits for respiratory disease. Methods: All records of daily outpatient visits to three hospitals in Shenzhen from January 1 to December 31, 2013 were collected. Daily air pollution monitoring and meteorology data from the same period were also collected in Shenzhen. The data were analyzed using a semiparametric generalized additive model with Poisson distribution of time series analysis controlling for long-term and seasonal trends, flu, DOW, public holidays, and meteorological factors. The excess risk(ER)of respiratory disease and its 95% CI value were calculated, along with the incremental increase of 10 μg/m3 in PM2.5 concentration. Results: Number of outpatient visits for respiratory diseases totaled 1 428 672(daily range: 1 790-5 228). The annual average PM2.5 concentration was 40.2 μg/m3(daily range: 7.2-137.1 μg/m3). The lag1 factor had the most significant impact on the lag effect. We estimated that a 10 μ g/m3 increase in day-before PM2.5 concentration was associated with a 1.809%(95% CI: 1.709%-1.909%)ER of visits for respiratory disease. After controlling for other pollutants(NO2, CO, and O3), the effect remained stable. When NO2, CO, and O3 were introduced separately, for every 10 μg/m3 rise in PM2.5 concentration, the excess risk of daily outpatient visits for respiratory disease was 1.814%(95% CI: 1.706%-1.923%), 2.780%(95% CI: 2.668%-2.892%), and 1.513%(95% CI: 1.403%-1.624%), respectively. With simultaneous control of NO2 and O3, NO2 and CO, and CO and O3, for every 10 μg/m3 rise in PM2.5 concentration, the excess risk of respiratory disease was 1.369%(95% CI: 1.242%-1.497%), 2.709%(95% CI: 2.590%-2.828%), and 2.577%(95% CI: 2.452%-2.702%), respectively. With simultaneous control of NO2, CO, and O3, for every 10 μg/m3 rise in PM2.5 concentration, the excess risk of respiratory disease was 2.370%(95% CI: 2.231%-2.509%). Conclusions: PM2.5 can increase the risk of outpatient visits for respiratory disease in Shenzhen.

Abstract
Purpose The number of cancer cases in China has increased rapidly from 2.1 million in 2000 to 4.3 million in 2015. As a consequence, pain management as an integral part of cancer treatment became an important health care issue. In March 2011, the Good Pain Management (GPM) program was launched to standardize the treatment of cancer pain and improve the quality of life for patients with cancer. With this work, we will describe the GPM program, its implementation experience, and highlight key lessons that can improve pain management for patients with cancer. Methods We describe procedures for the selection, implementation, and assessment procedures for model cancer wards. We analyzed published results in areas of staff training and patient education, pain management in practice, analgesic drugs administration, and patient follow-up and satisfaction. Results Pain management training enabled medical staff to accurately assess the level of pain and to provide effective pain relief through timely dispensation of medication. Patients with good knowledge of treatment of pain were able to overcome their aversion to opioid drugs and cooperate with nursing staff on pain assessment to achieve effective drug dose titration. Consumption of strong opioid drugs increased significantly; however, there was no change for weaker opioids. Higher pain remission rates were achieved for patients with moderate-to-severe pain levels. Proper patient follow-up after discharge enabled improved outcomes to be maintained. Conclusion The GPM program has instituted a consistent and high standard of care for pain management at cancer wards and improved the quality of life for patients with cancer.

Abstract
Depression is a common neuropsychiatric disorder which has been associated with a wide range of structural and functional changes within specific brain regions. Ginsenoside Rg1 has been shown to exert a number of neuroprotective effects as demonstrated in various in vivo and in vitro studies. However, little information is available regarding the site and mechanisms of ginsenoside Rg1 in promoting antidepressant effects. The present study aimed to investigate the neuroprotective and ameliorating effects of ginsenoside Rg1 on depression-like behavior as induced by chronic unpredictable mild stress (CUMS). The results showed that CUMS was effective in producing depression-like behaviors in rats as indicated by decreased responses in sucrose preference and forced swim tests which were associated with ultrastructural changes in neurons within the amygdala. Moreover, levels of PKA and CREB phosphorylation and the expression of brain-derived neurotrophic factor (BDNF) were decreased in the amygdala of CUMS rats. Remarkably, chronic ginsenoside Rg1 (40 mg/kg, i.p., 5 weeks) treatment significantly ameliorated these behavioral and biochemical alterations associated with CUMS-induced depression. Taken together, the results of the present study demonstrate that ginsenoside Rg1 exhibits antidepressant-like effects against CUMS-induced depression. This amelioration of depression-like behaviors by ginsenoside Rg1 appears to be mediated, at least in part, by a CREB-regulated increase of BDNF expression in the amygdala of rats. Therefore, these findings reveal the therapeutic potential of ginsenoside Rg1 for use in clinical trials in the treatment of depression.

Abstract
This study aims to research the effect of dihydroartemisinin on the proliferation, metastasis and apoptosis in human osteosarcoma cells 143B and the underlying mechanism. This study designed five groups for experiment and control, using dimethylsulfoxide (DMSO), and docosahexaenoic acid (DHA) at concentrations of 15, 25, 35 μmol.L-1 respectively. Experiments including methyl thiazolyl tetrazolium (MTT) assay, clone formation assay, Hoechst 33258 staining assay, luciferase reporter plasmid assay, Western blot and scratch test were carried out. In addition, SPSS 18.0 software from IBM was used for statistical analysis and all the data obtained from the experiments were expressed as mean ± SD, and variance was used to compare the difference between the groups. DHA is proved to be able to inhibit the proliferation and metastasis of osteosarcoma cells, as well as leaving a positive effect on apoptosis in the cytomorphosis. It achieves regulation over the human osteosarcoma cells by keeping the expression of related protein under control.

Abstract
OBJECTIVE In this study, we investigated the molecule mechanisms of podocyte injury and proteinuria and the protective effects of losartan. METHODS This study set up three groups: a control group; an Ang II group (Ang II 10(-6) mol/l, Sigma); and a losartan group (losartan 10(-6) mol/l, Sigma). We used RT-PCR assay to detect TRPC6 mRNA expression, and Western blot to detect TRPC6 protein expression. RESULTS TRPC6 overexpression was the basic change of podocyte injury and proteinuria occurrence. Losartan can treat podocyte injury and proteinuria induced by Ang II via downregulation of TRPC6 in podocytes. CONCLUSION These findings maybe provide an ideal drug target for the diagnosis and treatment of acquired glomerular diseases.

Abstract
Reduced radiosensitivity of lung cancer cells represents a pivotal obstacle in clinical oncology. The hypoxia-inducible factor (HIF)-1α plays a crucial role in radiosensitivity, but the detailed mechanisms remain elusive. A relationship has been suggested to exist between hypoxia and autophagy recently. In the current study, we studied the effect of hypoxia-induced autophagy on radioresistance in lung cancer cell lines. A549 and H1299 cells were cultured under normoxia or hypoxia, followed by irradiation at dosage ranging from 0 to 8 Gy. Clonogenic assay was performed to calculate surviving fraction. EGFP-LC3 plasmid was stably transfected into cells to monitor autophagic processes. Western blotting was used to evaluate the protein expression levels of HIF-1α, c-Jun, phosphorylated c-Jun, Beclin 1, LC3 and p62. The mRNA levels of Beclin 1 were detected by qRT-PCR. We found that under hypoxia, both A549 and H1299 cells were radio-resistant compared with normoxia. Hypoxia-induced elevated HIF-1α protein expression preferentially triggered autophagy, accompanied by LC3 induction, EGFP-LC3 puncta and p62 degradation. In the meantime, HIF-1α increased downstream c-Jun phosphorylation, which in turn upregulated Beclin 1 mRNA and protein expression. The upregulation of Beclin 1 expression, instead of HIF-1α, could be blocked by SP600125 (a specific inhibitor of c-Jun NH2-terminal kinase), followed by suppression of autophagy. Under hypoxia, combined treatment of irradiation and chloroquine (a potent autophagy inhibitor) significantly decreased the survival potential of lung cancer cells in vitro and in vivo. In conclusion, hypoxia-induced autophagy through evaluating Beclin1 expression may be considered as a target to reverse the radioresistance in cancer cells.

Abstract
The effects of connective tissue growth factor (CTGF) gene silencing on the radiosensitivity of glioblastoma cells (GBM) were investigated. The lentivirus-mediated short hairpin RNA (shRNA) expression vector targeting CTGF was constructed and transinfected into U87MG human GBM cell line. The CTGF gene expression in U87MG cells was significantly down-regulated. After irradiation with 6 MV X-rays at a dose rate of 2.5 Gy/min, the clonogenicity, proliferation and migration of U87MG cells were assayed in vitro. The survival, proliferation and migration of U87MG cells were all remarkably inhibited by CTGF silencing (p < 0.05 vs control). Our results demonstrate that CTGF is important for GBM and CTGF gene silencing can be a potential tool to enhance the sensitivity of GBM to radiotherapy.

Abstract
INTRODUCTION The aim of this study was to compare the efficacy and toxicity of dicycloplatin plus paclitaxel with those of carboplatin plus paclitaxel as first-line treatment for patients with advanced non-small-cell lung cancer (NSCLC). MATERIAL AND METHODS In this study, 240 NSCLC patients with stage IIIB (with pleural effusion) and stage IV disease were randomly assigned (1: 1) to receive dicycloplatin 450 mg/m(2) or carboplatin AUC = 5, in combination with paclitaxel 175 mg/m(2) (D + P or C + P) every 3 weeks for up to 4 to 6 cycles. The primary endpoint was response rate. Secondary endpoints included progression-free survival (PFS), overall survival (OS) and adverse events. RESULTS The response rates for the D + P and C + P arm were 36.44% and 30.51%, respectively (p = 0.33). The median PFS was 5.6 months in the D + P arm and 4.7 months in the C + P arm (p = 0.31). The median OS was 14.9 months for D + P and 12.9 months for C + P (p = 0.37). Adverse events in the two arms were well balanced. The most common grade 3/4 adverse event was hematologic toxicity. CONCLUSIONS Patients treated with D + P had similar response and survival rates to those treated with C + P, and toxicities of both treatments were generally tolerable.

Abstract
Annexin A3 participates in various biological processes, including tumorigenesis, drug resistance, and metastasis. The aim of this study was to investigate the expression of Annexin A3 in gastric cancer and its relationship with cell differentiation, migration, and invasion of gastric cancer cells. Annexin A3 expression in gastric cancer tissues was detected by quantitative real-time PCR and Western blotting. The proliferation of gastric cancer cells was measured by the MTT assay. Cell migration and invasion were determined via wound healing and transwell assays, respectively. Knock down of endogenous Annexin A3 in gastric cancer BGC823 cells was performed using siRNA technology. The expression of Annexin A3 was significantly upregulated in gastric cancer tissues, and negatively correlated with the differentiation degree. Silencing of endogenous Annexin A3 suppressed the proliferation, migration, and invasion of BGC823 cells. Additionally, the expression of p21, p27, TIMP-1, and TIMP-2 was upregulated, and the expression of PCNA, cyclin D1, MMP-1, and MMP-2 decreased in cells treated with Annexin A3-siRNA. Annexin A3 was upregulated in gastric cancer cells. Deletion of endogenous Annexin A3 significantly inhibited gastric cancer cell proliferation, migration, and invasion.

Abstract
The prevalence of BRCA1 gene mutations in breast cancer differs between diverse ethnic groups. Relatively little information is known about patterns of BRCA1 mutations in early-onset breast cancer in women of Uighur or Han descent, the major ethnic populations of the Xinjiang region in China. The aim of this study was to identify BRCA1 mutations in Uighur and Han patients with early-onset (age <35 years), and sporadic breast cancer for genetic predisposition to breast cancer. For detection of BRCA1 mutations, we used a polymerase chain reaction single-stranded conformation polymorphism approach, followed by direct DNA sequencing in 22 Uighur and 13 Han women with early-onset sporadic breast cancer, and 32 women with benign breast diseases. The prevalence of BRCA1 mutations in this population was 22.9% (8/35) among early-onset sporadic breast cancer cases. Of these, 31.8% (7/22) of Uighur patients and 7.69% (1/13) of Han patients were found to have BRCA1 mutations. In 7 Uighur patients with BRCA1 mutations, there were 11 unique sequence alterations in the BRCA1 gene, including 4 clearly disease-associated mutations on exon 11 and 3 variants of uncertain clinical significance on exon 11, meanwhile 4 neutral variants on intron 20 or 2. None of the 11 BRCA1 mutations identified have been previously reported in the Breast Cancer Information Core database. These findings reflect the prevalence of BRCA1 mutations in Uighur women with early-onset and sporadic breast cancer, which will allow for provision of appropriate genetic counseling and treatment for Uighur patients in the Xinjiang region.

Abstract
Accumulated evidence has revealed the presence of Notch receptor polymorphisms in non-tumorous diseases; however, few studies have investigated the association of Notch polymorphisms with breast cancer risk. A total of 100 invasive ductal carcinoma (IDC) and 50 ductal carcinoma in situ (DCIS) patients and 100 usual ductal hyperplasia (UDH) controls were genotyped for the following Notch receptor single nucleotide polymorphisms (SNPs) using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry: Notch1, rs3124591; Notch2, rs11249433; Notch3, rs3815188, and rs1043994; and Notch4, rs367398, and rs520692. Immunohistochemistry was used to determine the effect of Notch polymorphisms on corresponding Notch protein expression in successfully genotyped patients. The frequency of rs3124591 TC genotype was significantly higher in IDC (24.7%, 20/81) and DCIS (30%, 12/40) patients than in UDH controls (8%, 8/97) (P = 0.002 and P = 0.011, respectively). However, the distribution of other SNP genotypes was not significantly different between IDC and DCIS patients and UDH controls. The frequency of TC genotype was significantly higher in poorly differentiated tumors than in well-differentiated and moderately differentiated tumors (P = 0.022). Importantly, a positive correlation between the rs3124591 TC genotype and high Notch1 protein expression was observed in DCIS patients (P = 0.043) but not in IDC patients. This is the first study to suggest an increased risk of IDC and DCIS of the breast for the Notch1 rs3124591 variant. Furthermore, given the inconsistent associations between the rs3124591 variant and Notch1 expression in IDC and DCIS, this variant may affect breast cancer risk through mechanisms in the latter stage other than alterations in Notch1 protein expression.

Abstract
miR-200c has been shown to regulate the epithelial-mesenchymal transition (EMT) by inhibiting ZEB1 and ZEB2 expression in breast cancer cells. This study further examined the role of miR-200c in the invasion and metastasis of breast cancer that goes beyond the regulation on ZEB1 and ZEB2 expression. In this study, the bioinformatics software (miRanda) was used to predict the target gene of miR-200c and Renilla luciferase assay to verify the result. The metastatic breast cancer cells MDA-MB-231 were cultured and transfected with the miR-200c mimic or inhibitor. The expressions of miR-200c and HMGB1 were detected by RT-PCR and Western blotting, respectively. Transwell assay and wound healing assay were employed to examine the invasive and migrating ability of transfected cells. Target prediction and Renilla luciferase analysis revealed that HMGB1 was a putative target gene of miR-200c. After transfection of MDA-MB-231 cells with the miR-200c mimic or inhibitor, the expression of miR-200c was significantly increased or decreased when compared with cells transfected with the miR-200c mimic NC or inhibitor NC. Moreover, the expression of HMGB1 was reversely correlated with that of miR-200c in transfected cells. Tranwell assay showed that the number of invasive cells was significantly reduced in miR-200c mimic group when compared with miR-200c inhibitor group. It was also found that the migrating ability of cells transfected with miR-200c mimics was much lower than that of cells transfected with miR-200c inhibitors. It was suggested that miR-200c can suppress the invasion and migration of breast cancer cells by regulating the expression of HMGB1. miR-200c and HMGB1 may become useful biomarkers for progression of breast cancer and targets of gene therapy.

Abstract
The phosphorylation of nephrin plays an important role in maintaining the normal structure and function in podocytes. Dexamethasone (Dex) is usually used to treat glomerular diseases with proteinuria. In this study, we observated the effect of Dex and angiotensin II (AngII) on the change of nephrin phosphorylation in cultured podocytes. In vitro, cultured podocytes were exposed to AngII (10(-6) mol/L) pretreated with or without Dex (100 nM) for different time periods. Nck or Fyn were silenced by small interfering RNA (siRNA), nephrin and its phosphorylation expression were analyzed by Western blotting. In vitro, the phosphorylation of nephrin was significantly reduced after AngII stimulation (P < 0.05). Dex significantly resisted podocyte injury inducted by AngII via increasing the phosphorylation of nephrin (P < 0.05), siRNA silencing Nck can partially inhibited nephrin phosphorylation, siRNA silencing Fyn can completely inhibited nephrin phosphorylation. Phosphorylation of nephrin is important for the survival status of podocytes. Glucocorticoid treatment for human glomerulonephritis may exert its function by regulating Nck and Fyn complex to promote phosphorylation of nephrin. These results elucidate a novel mechanism of glucocorticoid treatment for glomerulonephritis.

Podocyte impairment is a key pathogenic even in the initiation and development of glomerular diseases associated with proteinuria. The type 2 diabetic patients is characterized by progressive increases in albuminuria which are associated with the development of characteristic histopathological features. Losartan had a benefit in decreasing albuminuria in type 2 diabetic patients,suggesting that losartan may have another effect other than blockade of the traditional renin-angiotensin system (RAS). However, the mechanism has remained undetermined. Glucose transporter 1 (GLUT1) is the predominant basal glucose transporter. In the kidney, GLUT1 was overexpressed predominantly in glomerular mesangial cells and in small vessels, rather than in podocytes. The increased glomerular GLUT1 mimicked diabetes-induced glomerular GLUT1 expression. In this study, we hypothesized that increased GLUT1 expression induced by angiotensinII (AngII) contributes to the progression of podocytes injury, losartan can block the effect of AngII and protect podocytes via stabilizing the expression of GLUT1, our results strongly suggest that losartan has a direct and protective effect on podocytes. This represents a novel mechanism by which losartan may protect podocyte from apoptotic death and improve podocyte function via stabilizing the expression of GLUT1. This finding underlines the crucial role of GLUT1 in the pathogenesis of podocyte injury and proteinuria.

Abstract
Although recent genome-wide association studies of esophageal squamous cell carcinoma (ESCC) identified a susceptibility locus in phospholipase C epsilon 1 (PLCE1) in Chinese Han populations, few studies further confirmed these findings in pure Kazakh population in which there are higher incidence and mortality of ESCC. Here, we investigated the potential associations between 19 SNPs of PLCE1 and susceptibility to ESCC in 222 cases and 326 controls from a pure ethnic population of Kazakh. Real-time PCR and immunohistochemistry were performed to detect the PLCE1 expression levels and evaluate their association with PLCE1 polymorphism. We found that only 4 SNPs (rs753724, rs11187842, rs2274223, and rs12263737) with moderate linkage disequilibrium (LD) confer significantly increased risk of ESCC, with the ORs ranging from 1.43 to 2.04, and there was a risk allele dose-dependent increase in ESCC risk (P-trend=0.043). Especially, the risk effects of rs2274223 were more evident in poor differentiation and advanced clinical stages of Kazakh ESCC. Additionally, the significantly lowest PLCE1 mRNA expression was found in the KYSE-150 cell line having no risk alleles compared with other three cell lines having risk alleles, and the normal tissues of both homozygous mutant type of PLCE1 rs12263737 and rs2274223 had a higher PLCE1 staining score than that of homozygous wild type. Our findings suggested that genetic variants in PLCE1 might serve as candidate markers for Kazakh ESCC susceptibility, and these LD variants might influence ESCC risk individually and jointly by promoting the messenger RNA and protein expression of the gene.
