Abstract
PURPOSE Cetuximab (CTX) has been used to treat metastatic colorectal cancer (mCRC) with wild-type (wt) RAS and BRAF genes. Meanwhile HER2 amplification reportedly denoted CTX-resistant mCRC tumors. We investigated whether monitoring of HER2 amplification in circulating DNA allowed early detection of mCRC progression and CTX resistance. METHODS mCRC, who progressed after CTX treatments between July 2015 and January 2018. RESULTS Of the 36 patients, 5 (13.9%) exhibited dynamic fluctuations of HER2 amplification in plasma in the course of CTX treatment, of whom 2 were positive for HER2 amplification in matched tumor specimens at baseline (per FISH). All 5 primary sites were left side: 3 rectums and 2 descending colon. HER2 ratio fluctuations in circulating DNA not only reflected changes in tumor volume, but their obvious increases presaged CT-documented progress by an average lead time of 2 months. Interestingly, progression-free survival did not significantly differ between these 5 patients and those without HER2 amplification (HR 1.06, 95% CI 0.40-2.77, P = 0.909). CONCLUSION Plasma HER2 amplification detected by ddPCR changed over time and predicted resistance to CTX, by an average lead time of 2 months. Further study is needed to validate our findings.

Abstract
BACKGROUND Blepharophimosis syndrome (BPES) is characterized by eyelid malformation with occasional premature ovarian failure. Mutations in FOXL2 underlie a fraction of BPES cases. OBJECTIVE We aimed to investigate the genetic basis of BPES in 26 Chinese families that included 78 patients. METHODS We performed ophthalmological examinations on each family member. We used Sanger sequencing to screen FOXL2 exons and their flanking sequences. We also performed bioinformatics studies, structural modeling and pathogenicity evaluations on all identified variations. Literature was reviewed and genotype-phenotype correlation analysis was performed. RESULTS The patients had typical manifestations of BPES. Ten mutations were identified in ten of the twenty-six families. Among these, seven were novel mutations. These included the six truncating mutations, p.Glu69*, p.Gly256Glyfs*14, p.Ala14Serfs*135, p.Pro333Profs*200, p.Pro290Leufs*70, and p.Pro157Profs*91, and one missense mutation, p.Tyr59Cys. The mutations were scattered within the gene, and no mutational hotspots were found. Genotype-phenotype correlation analysis showed that frameshift or nonsense mutations were correlated with type I BPES, while in-frame or missense mutations were associated with type II BPES. CONCLUSION We report the largest BPES cohort in China thus far as well as seven novel mutations in FOXL2. The identification of novel mutations has not only expanded the mutational spectrum of the gene (which is valuable for mutation detection-based screening) but also suggests that most mutations within the Chinese population may not have been characterized yet.

Abstract
OBJECTIVE The paper aims to explore the application of dexmedetomidine combined with dezocine in thoracoscopic radical resection of lung cancer and its effect on the awakening quality. PATIENTS AND METHODS 122 patients undergoing thoracoscopic radical resection of lung cancer in The Affiliated Hospital of Qingdao University from April 2009 to January 2012 were selected as the subjects of the study. Among them, 68 patients were anesthetized with dexmedetomidine combined with dezocine as a study group, 54 patients with midazolam combined with fentanyl as a control group. The onset of anesthetic, operation time, awakening time, extubation time, and recovery time was compared. The mean arterial pressure (MAP), central venous pressure (CVP), and heart rate (HR) were compared before anesthesia (t0), at extubation (t1), 10 min after extubation (t2), and when patients left anesthesia recovery room (t3). The postoperative sedation score (Ramsay), modified the objective pain score (MOPS), and the pediatric anesthesia emergence delirium (PAED) score were compared at the time of the postoperative awakening (b1), 30 min after awakening (b2), 1 hour after awakening (b3), and 3 hours after awakening (b4). RESULTS There was no significant difference in MAP, CVP, and HR between the study group and the control group at t0 (p > 0.05). The scores of PAED at b3 and b4 in the study group were lower than those in the control group (p < 0.05). CONCLUSIONS The anesthesia effect of dexmedetomidine combined with dezocine in thoracoscopic radical resection of lung cancer is better and safer than other drugs, and it can produce good sedation and analgesic effect.

Abstract
Molluscum contagiosum is a common, self-limiting infectious disease of the skin caused by molluscum contagiosum virus (MCV). The disease primarily affects children, sexually active adults, and immunocompromised individuals. Transmission of the virus occurs by direct skin contact. Therefore, the virus is usually detected in the skin and genitals of patients. However, the diagnosis of intracranial infection by the virus is difficult if the skin/mucosa lessons are atypical or absent, and the presence of the virus in the cerebrospinal fluid has not been reported. We report a very rare case of intracranial infection by molluscum contagiosum virus. A 25-year-old girl was admitted to our hospital due to severe headache but no fever or other symptoms. Upon examination, some small flesh-colored flattened papules on both arms were noticed. Blood tests showed slightly reduced levels of CD3 and CD4 T lymphocytes. Three-dimensional time-of-flight magnetic resonance angiography (3D-TOF-MRA) and head magnetic resonance (MR) were both normal. Lumbar puncture was performed, and metagenomic sequencing was applied to the spinal fluid. The unique sequences of the molluscum contagiosum virus were identified in the fluid. The patient was then diagnosed with intracranial molluscum contagiosum virus infection. No special treatment was given. The headache gradually disappeared, and the patient was discharged. During our quarterly follow-up, the girl appeared normal, and her skin lesions disappeared. However, her CD3 and CD4 T lymphocyte counts were still slightly lower than the normal level. Our case shows that the application of metagenomic sequencing to cerebrospinal fluid is a sensitive and powerful means to detect pathogens causing intracranial infection. Keywords: Molluscum contagiosum; intracranial infection; metagenomics sequencing.

Abstract
Bone fractures are a medical condition where the continuity of the bone is broken due to a fall or accident. The fracture may also be the result of medical conditions such as osteoporosis, cancers of bone or osteogenesis imperfect. During the bone fracture healing process, the mesenchymal stem cells (undifferentiated connective tissue cells) are recruited from local and systemic sources. The modulation of mesenchymal cell migration to the fractured site is the desired goal. Still, there are many processes that are still required to be studied and analyzed. We aimed to consolidate and review the available information on this topic.

Abstract
OBJECTIVE To study the expression and significance of micro ribonucleic acid (miR)-126 and vascular endothelial growth factor (VEGF) in the vitreous body and proliferative membrane tissues of affected eyes and plasma in proliferative diabetic retinopathy (PDR). PATIENTS AND METHODS A total of 50 PDR patients admitted to our hospital from January 2017 to January 2018 were collected, including 17 cases in stage IV, 20 cases in stage V, and 13 cases in stage VI according to the DR staging criteria. Another 30 patients with an idiopathic macular hole were selected as control group. After admission, the examinations were performed, venous blood was drawn, and vitrectomy was performed, during which the vitreous body and proliferative membrane tissues were taken. The plasma VEGF content was detected via enzyme-linked immunosorbent assay (ELISA). The VEGF protein expression level was detected via Western blotting in vitreous body and proliferative membrane tissues. Moreover, the miR-126 expression was detected via quantitative polymerase chain reaction (qPCR). RESULTS In the vitreous body tissues, proliferative membrane tissues and plasma, the expression level of miR-126 was significantly lower in control group than that in stage IV, V, and VI groups (p<0.05). The miR-126 expression was significantly lower in stage IV group than that in stage V and VI groups (p<0.05), meanwhile, miR-126 expression was significantly lower in stage V group than that in stage VI group (p<0.05). In the vitreous body tissues, proliferative membrane tissues and plasma, the VEGF mRNA and protein expression levels were significantly higher in control group than those in stage IV, V, and VI groups (p<0.05). The VEGF expressions were significantly higher in stage IV group than those in stage V and VI groups (p<0.05). In addition, VEGF expressions were significantly higher in stage V group than those in stage VI group (p<0.05). Furthermore, the VEGF expression level was negatively correlated with the miR-126 expression level. CONCLUSIONS We found that the abnormally high expression of miR-126 negatively regulates VEGF, which may be one of the important mechanisms of occurrence of PDR. The miR-126 and VEGF content can serve as important predictors for the condition of PDR.

Abstract
Exosomes are tiny vesicles secreted by most endogenous cells, and the extracellular vesicles (EVs) are specifically secreted by cells. Recently, it was found that exosomes contain a large quantity of important substances such as proteins, nucleic acids, and lipids, which play important roles in material exchange and information transmission in cell-cell communication, and in modulating the immune response, metabolism, and expansion, metastasis, and drug resistance of tumors. This paper summarizes the recent researches on exosomes in parasites and parasitic diseases and hopes to be helpful for improving the researches of parasites and parasitic diseases.

Abstract
OBJECTIVE To investigate determinants of decrease and increase in joint pain in symptomatic finger osteoarthritis (OA) on magnetic resonance (MR) imaging over 2 years. DESIGN Eighty-five patients (81.2% women, mean age 59.2 years) with primary hand OA (89.4% fulfilling American College of Rheumatology (ACR) classification criteria) from a rheumatology outpatient clinic received contrast-enhanced MR imaging (1.5T) and physical examination of the right interphalangeal finger joints 2-5 at baseline and at follow-up 2 years later. MR images were scored paired in unknown time order, following the Hand OA MRI scoring system (HOAMRIS). Joint pain upon palpation was assessed by research nurses. Odds ratios (ORs; 95% confidence intervals) were estimated on joint level (n = 680), using generalized estimating equations (GEE) to account for the within patient effects. Additional adjustments were made for change in MR-defined osteophytes, synovitis, and bone marrow lesions (BMLs). RESULTS Of 116 painful joints at baseline, at follow-up: 76 had less pain, 21 less synovitis, and 13 less BMLs. A decrease in synovitis (OR = 5.9; 1.12─31.0), but not in BMLs (OR = 0.39; 0.10─1.50), was associated with less pain. Of 678 joints without maximum baseline pain, at follow-up: 115 had increased pain, 132 increased synovitis, 96 increased BMLs, and 44 increased osteophytes. Increased synovitis (OR = 1.81; 1.11─2.94), osteophytes (OR = 2.75; 1.59─4.8), but not BMLs (OR = 1.14; 0.81─1.60), was associated with increased pain. Through stratification it became apparent that BMLs were mainly acting as effect modifier of the synovitis-pain association. CONCLUSION Decrease in MR-defined synovitis is associated with reduced joint pain, identifying synovitis as a possible target for treatment of finger OA.

Abstract
Background Workplace presenteeism is common and leads to the spread of infectious diseases. Previous reviews have focused on presenteeism in relation to general physical or mental ill health. In this systematic review we identified the prevalence of, and reasons and risk factors for, presenteeism in relation to an infectious illness. Method We searched Medline, Scopus, Web of Science, PsycINFO and PsycARTICLES with terms relating to infectious illnesses and presenteeism at the work place or school; reference lists of relevant articles were also hand-searched. Result Our search yielded 3580 papers after deduplication. After title, abstract and full text screening, 23 papers reporting on 24 studies were included. Twenty-three studies were cross-sectional studies and one was prospective. The quality of included studies was relatively poor due to problems such as sampling and non-response bias. Presenteeism prevalence ranged from 35 to 97%. Self-reported reasons for presenteeism fell into three main themes: 1. Organisational factors (organisational policy, presenteeism culture, disciplinary action), 2. Job characteristics (lack of cover, professionalism, job demand), and 3. Personal reasons (burden on colleagues, colleague perceptions, threshold of sickness absence and financial concerns). Statistical risk factors fell into four themes: 1. Sociodemographic, 2. Health, 3. Influenza-related behaviour, and 4. Employment characteristics. Most of the risk factors had insufficient evidence to allow us to draw any firm conclusions, and evidence regarding gender and age was inconsistent. The risk factor with the most consistent findings concerned occupation type, suggesting that those who worked in the healthcare sector, and specifically physicians, were at a higher risk of infectious illness presenteeism. Conclusion Infectious illness presenteeism is common. To address the public health consequences, organisations should focus on promoting a positive working culture and developing sickness absence policies that reduce presenteeism. Further research is needed in non-health sector organisations and schools to identify risk factors related to different organisations, which can then be used to tailor interventions at the organisational and individual level.

Abstract
Abstract Objective To study the expressions of transforming growth factor-β1 (TGF-β1) and EⅢA-fibronectin (EⅢA-FN) at different time points of antemortem injury, antemortem injury postmortem expression and postmortem injury and to explore their application value in wound age estimation. Methods A model of rat skeletal muscle contusion was established. The rats were randomly divided into normal control group (n=5), antemortem contusion group (n=40), antemortem contusion postmortem expression group (n=110) and postmortem injury group (n=25). The expressions of TGF-β1 and EⅢA-FN after rat skeletal muscles antemortem contusion were detected with immunohistochemical staining. Expression changes of TGF-β1 and EⅢA-FN mRNA in each group were analyzed with real-time fluorescence quantitative PCR. Results Immunohistochemical staining results showed that a large number of polymorphonuclear leukocyte, mononuclear cells and fibroblastic cells showed a strong expression of TGF-β1 in wounded zones 12 h-14 d after antemortem contusion. EⅢA-FN was mainly distributed in the extracellular matrix, 3 to 7 d post-traumatic. Real-time fluorescence quantitative PCR results showed that TGF-β1 and EⅢA-FN mRNA in antemortem injury group reached the peak at 3 and 5 d post-traumatic respectively. The expressions of TGF-β1 and EⅢA-FN mRNA in antemortem contusion postmortem expression group peaked at 6 h and 12 h postmortem. The expression of TGF-β1 and EⅢA-FN mRNA in postmortem injury group 0.5-12 h postmortem was significantly lower than those of the normal control group and the antemortem contusion group. Conclusion TGF-β1 and EⅢA-FN might become a reference index for skeletal muscle wound age estimation.

Abstract
Objective: To analyze the correlation between urinary albumin/creatinine ratio (ACR) and 24-hour urinary microalbumin (UMA) and evaluate the predictive value of ARC for early diabetic nephropathy. Methods: A total of 368 patients with type 2 diabetes mellitus were retrospectively collected. Early diabetic nephropathy was defined as 24h UMA 30~<300 mg/24h. The correlation between ACR and 24hUMA, and the area under the receiver operating characteristic (ROC) curve of ACR in diagnosis of early diabetic nephropathy were calculated. Gender, age, course of disease, fasting venous blood glucose, glycosylated hemoglobin, blood pressure, triglyceride and total cholesterol were used as adjusting variables to establish univariate and multivariate logistic models of ACR for early diabetic nephropathy, respectively. A regression model was used to evaluate the diagnostic value of ACR for early diabetic nephropathy. Results: The correlation between ACR and 24h UMA was 0.658. The area under ROC curve of ACR for early diabetic nephropathy was 0.907 before and 0.933 after adjustments of gender, age, course of disease, fasting venous blood glucose, glycosylated hemoglobin, blood pressure, triglyceride and total cholesterol, respectively. The OR value of ACR of diabetic nephropathy was 2.016 before and 2.762 after same adjustments. The calibration of Hosmer-Lemeshow chi-square test evaluation model was 19.362 before (P=0.13) and 14.928 after adjustments (P=0.061). Conclusion: ACR is a better predictor for early diabetic nephropathy although its value is influenced by gender, age, course of disease, blood sugar, lipid, and blood pressure.

Abstract
Objective: To investigate the long-term prognosis of Second generation drug-eluting stents(G2-DES) in diabetic mellitus(DM) and non-DM patients. Methods: Patients with coronary heart disease(CHD) in Fuwai Hospital from January 2013 to December 2013 who had exclusively G2-DES implantation, were consecutively included the follow-up period was 2 years. Results: A total of 6 094 patients with CHD were implanted with G2-DES, of which 1 862 patients with DM, and 4 232 patients without DM.The proportion of DM patients receiving G2-DES implantation with the following characteristics: advanced age, female, hypertension, hyperlipidemia, history of previous stroke, history of peripheral artery disease, previous history of PCI, and with triple vessel, high preoperative Syntax score, high number of target lesions, B2 or C type lesions, severe calcification lesions, and chronic occlusive disease were significantly higher than those of non-DM patients(P<0.05). The incidence of major adverse cardiac and cerebral vascular events(MACCE), target vascular revascularization(TVR) and target lesion revascularization(TLR) were higher in DM patients than in non-DM patients during 2 year's follow-up(P<0.05). The univariate COX regression analysis showed that diabetes was risk factor for MACCE in patients with CHD implanting G2-DES(HR=1.241, 95%CI: 1.053-1.463, P=0.010). However, multivariable COX analysis showed that DM was not an independent risk factor for MACCE in CHD patients with G2-DES(HR=1.125, 95%CI: 0.952-1.330, P=0.167). While age, female, preoperative Syntex score, triple vessel, B2 or C lesion were independent risk factors for poor clinical prognosis in CHD patients with G2-DES. Conclusions: (1) CHD patients with DM often accompany more clinical risk factors and complicated coronary lesions; (2) the incidence of MACCE, TVR and TLR in DM patients is significantly higher than non-DM patients with G2-DES during the 2 year's follow-up; (3) after multivariate adjustment, DM is not an independent risk factor for poor clinical prognosis in CHD patients with G2-DES, while traditional risk factors and complex coronary lesions are independent risk factors for poor clinical prognosis.

Abstract
OBJECTIVE To investigate the construct validity of the new thumb base OA magnetic resonance imaging (MRI) scoring system (TOMS) by comparing TOMS scores with radiographic scores in patients with primary hand OA. DESIGN In 200 patients (83.5% women, mean (SD) age 61.0 (8.4) years), postero-anterior radiographs and MR scans (1.5 T) of the right first carpometacarpal (CMC-1) and scaphotrapeziotrapezoid (STT) joints, were scored using the OARSI atlas and TOMS, respectively. The distributions of the TOMS scores (specified in results section) were stratified for the OARSI scores of corresponding radiographic features and investigated using boxplots and non-parametric tests. Furthermore, Spearman's rank or Phi correlation coefficients (ρ/φ) were calculated. RESULTS For all features, especially for erosions and osteophytes, the prevalence found with MRI was higher than with radiography. TOMS osteophyte and cartilage loss scores differed statistically significant between corresponding OARSI scores in CMC-1 (0 vs 1; 1 vs 2). TOMS scores were positively correlated with radiographic scores in CMC-1 for osteophytes (coefficient [95% confidence interval], ρ = 0.75 [0.69; 0.81]), cartilage loss/joint space narrowing (ρ = 0.70 [0.62; 0.76]), subchondral bone defects (SBDs)/erosion-cyst (ρ = 0.41 [0.29; 0.52]), bone marrow lesions (BMLs)/subchondral sclerosis (ρ = 0.65 [0.56; 0.73]) and subluxation (φ = 0.65 [0.57; 0.73]); and in STT for osteophytes (ρ = 0.30 [0.17; 0.42]) and cartilage loss/joint space narrowing (ρ = 0.53 [0.42; 0.62]). CONCLUSIONS In patients with hand OA, TOMS scores positively correlated with radiographic scores, indicating good construct validity. However, the prevalence of features on MR images was higher compared to radiographs, suggesting that TOMS might be more sensitive than radiography. The clinical meaning of these extra MR detected cases is currently still unknown.

Abstract
AIM To find potential predictors at unenhanced computed tomography (CT) to evaluate the stone clearance rate (SCR) of pancreatic duct stones (PDS) by extracorporeal shock wave lithotripsy (ESWL). MATERIALS AND METHODS A total of 106 consecutive patients with multiple stones of maximal transverse length (MTL) 0.3-3.6 cm in pancreatic head region were enrolled. Unenhanced CT was performed both before and after ESWL therapy. All patients underwent ESWL therapy using an electromagnetic lithotripter, and were divided into three groups with threshold values of >90%, 50-90% and <50% of SCR. Factors including sex, age, MTL, mean stone density (MSD), standard deviation of stone density (SDSD), variation coefficient of stone density (VCSD), attenuation density (AD), pancreatic duct diameter (PDD), skin-to-stone distance (SSD), and number of ESWL sessions were analysed, and their impact on SCR was evaluated by univariate and multivariate analyses. The diagnostic threshold of the independent predicting index was further calculated, and its relationship with SCR and ESWL was analysed by drawing a trend line. RESULTS The only significant predictor of SCR by ESWL was MSD (p<0.05). More courses of ESWL therapy are required in PDS patients with an MSD higher than the cut-off value of 375.4 HU (mean, 2.6 versus 1.8), but with a relatively lower SCR (mean, 43.96 versus 88.68%) . CONCLUSION MSD on pre-treatment unenhanced CT is an independent predictor for SCR of PDS patients treated with ESWL. Using a cut-off value of 375.4 HU, patients with low MSD are good candidates for ESWL therapy.

Abstract
Abstract
Introduction: Tumor-associated macrophages (TAMs) play an important role in the process of tumor metastasis. Previous studies have shown that TAMs induce breast cancer cells undergo epithelial-mesenchymal transition (EMT) by secreting CCL18. Reciprocally, the induced mesenchymal-like breast cancer cells activate macrophages into a TAM-like phenotype via secreting the cytokine granulocyte-macrophage colony stimulating factor (GM-CSF), forming a positive feedback loop that is essential to breast cancer metastasis.
Methods: To better understand the underlying mechanism that links this positive feedback loop to breast cancer metastasis, a TAMs-induced EMT cell model (MCF-7) was used. RNA-seq was used to compare the transcriptome of MCF-7 cells which were cocultured with TAMs and those with or without monocyte-derived macrophages (MDMs). Results were further verified by qRT-PCR.
Results: Among 811 known protein-coding genes with reliable readouts, 42 were significantly changed between groups (P<0.001). Further analysis using KEGG, Reactome and Wikipathways databases found that these 42 genes were enriched in 15 signal pathways (P<0.01). According to their biological function, these pathways can be divided into 5 functional groups: SUMOylation related, virus related, immune related, interferon related and cytokine related. The last 3 groups demonstrated that our model were representative and able to provide some real and useful information, while SUMOylation and virus related signal pathways have never been reported to be involved in TAMs induced breast cancer metastasis.
Conclusion: We investigated the transcriptome alteration of MCF-7 cells in the process of TAMs-promoted metastasis. Results from bioinformatic analysis indicated SUMOylation and virus related signal pathways in the process of TAMs induced breast cancer metastasis, which are yet to be confirmed.

Abstract
Objective: To investigate the effects of proteasome beta 5 subunit (PSMB5) on proliferation and bortezomib (BTZ) chemo-sensitivity of multiple myeloma (MM) and its related molecular mechanisms. Methods: We used two MM cell lines, RPMI 8226 and BTZ drug-resistant cell line RPMI 8226/BTZ100 (hereinafter referred to as BTZ100) , as the research object. PSMB5 was overexpressed or knocked down in two myeloma cell lines via lentivirus transfection. CCK8 assay was used to detect the impact of PSMB5 on cell viability and bortezomib sensitivity in human myeloma cells; Using flow cytometry to test the effects of PSMB5 on apoptosis rate of human myeloma cells under the treatment of bortezomib; Apoptosis-related gene expression of Bax, Bcl-2, p-Akt and cleaved caspase-3 were detected by Western blot. Results: ①PSMB5 overexpression and knockdown were successfully constructed in RPMI 8226 and BTZ100 cells. ②PSMB5 expression was positively correlated with cell proliferation of RPMI 8226 and BTZ100 cells (P<0.05) . ③The cell viability was lower after PSMB5 knockdown in RPMI 8226 cells than control cells under the same concentration of BTZ[IC(50) at 24 h: (7.01±0.47) and (9.64±0.55) nmol/L respectively, t=6.289, P=0.003]. The cell viability was higher after PSMB5 overexpression in RPMI 8226 cells than control cells under the same concentration of BTZ[IC(50) at 24 h: (10.99±0.58) and (9.51±0.37) nmol/L respectively, t=3.724, P=0.020) . PSMB5 expression was negatively correlated with the sensitivity of RPMI 8226 cells to BTZ. The results of BTZ100 cells were similar. ④The expression of PSMB5 was negatively correlated with the apoptosis of RPMI 8226 and BTZ100 under the treatment of BTZ. ⑤Meanwhile, PSMB5 knockdown could increase the expression of pro-apoptosis gene Bax and cleaved caspase-3 and decrease the expression of anti-apoptotic gene Bcl-2 and p-Akt. PSMB5 over-expression has the opposite results. Conclusion: PSMB5 knockdown could improve the bortezomib sensitivity of MM cells via activation of apoptosis signaling. PSMB5 may be a potential therapeutic target for MM.

Abstract
Objective: Patients with acute coronary syndrome due to multivessel disease (MVD) were at the highest risk of adverse cardiovascular events. Neutrophil to lymphocyte ratio (NLR) was proposed as a marker of cardiovascular risk. Present study evaluated the independent predictive value of NLR for acute myocardial infarction (AMI) patients with MVD. Methods: AMI patients with MVD (n=1 433) underwent percutaneous coronary intervention (PCI) between January 2013 and December 2013 were followed up for 2 years. Patients were divided into 2 sub-groups based on an optimal cut off value of NLR to predict 2-year all-cause mortality. The primary endpoint was all-cause death. The secondary endpoint was long-term major adverse cardiovascular and cerebrovascular events (MACCE). Results: By receiver operating characteristics curve analysis, the optimal cut-off value of admission NLR to predict 2-year all-cause mortality was 3.39 (area under the curve 0.765, sensitivity 71%, specificity 73%). The high NLR group(n=396) had higher prevalence of prior myocardial infarction, prior PCI and intra-aortic balloon pump use (IABP)(P<0.01). Compared to the low NLR group (n=1 037), patients in the high NLR group were older, had higher level of neutrophil count and high-sensitivity C-reactive protein (hs-CRP) (P<0.001), but lower level of lymphocyte count, estimated glomerular filtration rate (eGFR) and ejection fraction (P<0.001). During the follow-up period, rate of long-term all-cause death was significantly higher in the high NLR group than in the low NLR group (5.1% (20/396) vs. 0.8% (8/1 037), P<0.001). Cardiac death (4.0% (16/396) vs. 0.7% (7/1 037), P<0.001) and MACCE (21.7% (86/396) vs. 12.6% (131/1 037), P<0.001) were also significantly higher in the high NLR group than in the low NLR group. Multivariate Cox analysis showed that NLR ≥ 3.39 was determined as an independent predictor of 2-year all-cause mortality (HR=3.23, 95%CI 1.38-7.54, P=0.007) and MACCE (HR=1.58, 95%CI 1.19-2.10, P=0.002) in this patient cohort after adjusting for other risk factors. Correlation analysis showed that the NLR was positively correlated with hs-CRP levels (r=0.241, P<0.001). Conclusion: Our study demonstrates that admission NLR ≥ 3.39 is an independent predictor of long term all cause death and MACCE in AMI patients with MVD post PCI.

Abstract
Acute kidney injury (AKI) is an increasing clinical problem that is associated with chronic kidney disease progression. Cannabinoid receptor 2 (CB2) activation has been shown to mitigate some of the deleterious tubular effects due to AKI, but its role on the renal vasculature has not been fully described. In this study, we investigated the effects of our novel CB2 receptor agonist, SMM-295, on renal vasculature by assessing cortical perfusion with laser Doppler flowmetry and changes in luminal diameter with isolated afferent arterioles. In this study, intravenously infused SMM-295 (6 mg/kg) significantly increased cortical renal perfusion (13.8 ± 0.6%; P < 0.0001; n = 7) compared with vehicle (0.1 ± 1.5%; n = 10) normalized to baseline values in anesthetized C57BL/6J mice. This effect was not dependent upon activation of the CB1 receptor (met-anandamide; 6 mg/kg iv) and was predominantly abolished in Cnr2 knockout mice with SMM-295 (6 mg/kg iv). Ablation of the renal afferent nerves with capsaicin blocked the SMM-295-dependent increase in renal cortical perfusion, and the increased renal blood flow was not dependent upon products synthesized by cyclooxygenase or nitric oxide synthase. The increased renal perfusion by CB2 receptor activation is also attributed to a direct vascular effect, since SMM-295 (5 μM) engendered a significant 37 ± 7% increase ( P < 0.0001; n = 4) in luminal diameters of norepinephrine-preconstricted afferent arterioles. These data provide new insight into the potential benefit of SMM-295 by activating vascular and nonvascular CB2 receptors to promote renal vasodilation, and provide a new therapeutic target to treat renal injuries that impact renal blood flow dynamics.

Abstract
With the development of society and the improvement of medical level, the average life span of human has been increasing year by year. The proportion of elderly burn patients is also increasing yearly, which has become a social problem that can not be ignored. Because of physiological characteristics, such as decreased function of heart, lung, and kidney, degenerative changes of neural system, reduced gastrointestinal function and immunological function, and mostly accompanied by primary diseases of diabetes and cardiovascular diseases, elderly burn patients suffer from high shock rate and mortality, and their wounds are not easy to heal. With the purpose of providing ideas for prevention and treatment of elderly burn patients, this review summarizes the physiological characteristics, wound treatment, fluid resuscitation, organ protection, nutrition support, and psychological guidance of elderly burn patients.

Abstract
Objective: To investigate the impact of coronary lesion calcification on the long-term outcome of patients with coronary heart disease after percutaneous coronary intervention. Methods: In this prospective observational study, a total of 10 119 consecutive patients with coronary heart disease undergoing percutaneous coronary intervention from January 1 to December 31, 2 103 in our hospital were enrolled. The patients were divided into non/mild calcification group (8 268 cases) and moderate/severe calcification group (1 851 cases) according to the angiographic results. The primary endpoint was one-year major adverse cardiovascular events (MACE), including all-cause death, myocardial infarction, and target vessel revascularization. Results: The patients were (58.3±10.3) years old, and there were 2 355 females (23.3%). Compared with non/mild calcification group, patients in the moderate/severe calcification group were older ((60.0±10.6) years vs. (57.9±10.2) years, P<0.01), and had higher proportion of female (25.4% (470/1 851) vs. 22.8% (1 885/8 268), P=0.02), debates (33.9% (628/1 851) vs. 29.0% (2 399/8 268), P<0.01), hypertension (68.0% (1 259/1 851) vs. 63.7% (5 264/8 268), P<0.01), coronary artery bypass grafting (4.6% (85/1 851) vs. 3.2% (268/8 268), P<0.01), stroke (12.6% (233/1 851) vs. 10.4% (861/8 268), P=0.01), and renal dysfunction (6.2% (115/1 851) vs. 3.7% (303/8 268), P<0.01). Compared with non/mild calcification group, patients in themoderate/severe calcification group experienced longer procedure time (37 (24, 61) min vs. 27 (17,40) min, P<0.01) and stent length was longer (32 (23,48) mm vs. 27 (18,38) mm, P<0.01), and percent of rotational atherectomy was higher (2.56%(57/2 229) vs. 0.03% (3/11 930), P<0.01). One-year follow-up results showed that MACE (7.5% (139/1 846) vs. 4.9% (402/8 243), P<0.01), all-cause death (1.0% (19/1 846) vs. 0.6% (49/8 243), P=0.04), myocardial infarction (2.2% (41/1 846) vs. 1.4% (114/8 243), P=0.01), and target vessel revascularization (5.0% (92/1 846) vs. 3.2% (266/8 243), P<0.01) were all significantly higher in moderate/severe calcification group than in non/mild group. Multivariate Cox regression analysis showed that moderate/severe calcification was an independent predictor of MACE at one-year after the procedure (HR=1.41, 95%CI 1.16-1.72, P<0.01). Conclusion: Moderate/severe calcification in coronary lesion is an independent predictor of long-term poor prognosis in coronary heart disease patients undergoing percutaneous coronary intervention.

Abstract
Soil erosion in karst areas not only destroys the natural environment but also accelerates the decline in land productivity together with the associated increase in poverty for local communities. There are no simple or straightforward answers to controlling soil erosion on karst. Such erosion has become a serious problem in China. This study addresses both the diversity of vegetation (mosses, herbs, shrubs and trees) on karst and the underlying soil chemical characteristics, in order to provide a scientific basis by which suitable plant species can be selected for recovery and restoration of karst degraded by soil erosion. Vegetation diversity and soil chemistry were assessed in areas with five different grades of soil erosion in Guiyang Karst Park, Guizhou, China. Mosses are more tolerant than vascular plants of soil erosion and associated environmental degradation of karst and the order of species diversity was: mosses > herbs > shrubs > trees. Mosses were found to play a major role in ecological restoration of microhabitats on karst. Soil microbial biomass carbon was found to be significantly higher in soil under mosses than in bare soil associated with other plant categories. Mosses were more effective in converting unavailable potassium to available potassium. Vascular plants were found to have a positive effect on total nitrogen fixation and the availability of phosphorus in the soil. Increasing soil degradation was associated with lower levels of total Nitrogen in soil underlying mosses than in soil underlying vascular plants. Thus, based on their different but complementary contributions to soil chemistry, mosses and vascular plants in combination can provide the most practical outcome for the repair and restoration of areas of karst affected by soil erosion. The combination of the moss species, Homomallium plagiangium, Cyrto-hypnum pygmaeuman and Brachythecium perminusculum, the herbs Veronica arvensis and Youngia japonica, and the tree Prunus salicina, are recommended as suitable pioneer plant species to cultivate for use in restoration of regions of karstic soil erosion.

Abstract
Ovarian cancer is a gynecological malignancy worldwide. Long non-coding RNAs (lncRNAs) research is an emerging area in cancer studies, but little is known about lncRNA metastasis associated lung adenocarcinoma transcript 1 (MALAT1) in ovarian cancer. This study aims to investigate expression and roles of MALAT1 in ovarian cancer. MALAT1 level was detected in 20 ovarian cancer patients. MALAT1 expression was promoted by transforming growth factor β1 (TGFB1) treatment and inhibited by siRNA transfection in human ovarian cancer cell line SK-OV-3, after which changes in cell viability, proliferation, migration and invasion were analyzed by MTT, colony formation and Transwell assays. Protein levels of mitogen-activated protein kinase factors, including MAPK kinase 1 (MEK1), extracellular signal-regulated kinase (ERK1), p38 and c-Jun N-terminal kinase 1 (JNK1), were detected by western blot. Results showed that MALAT1 was significantly up-regulated in ovarian cancer tissues compared to adjacent normal tissues (P < 0.001), and its expression was correlated to tumor size (r2 = 0.7770, P < 0.0001) and metastasis. TGFB1 and siRNA successfully altered MALAT1 levels in SK-OV-3 cells. Knockdown of MALAT1 suppressed SK-OV-3 cell viability, proliferation, migration and invasion (P < 0.05), and inhibited phosphorylation of MEK1, ERK1, p38 and JNK1, which suggested that MALAT1 promoted ovarian cancer cell proliferation, migration and invasion, and that MAPK pathways might be one of the regulatory mechanisms of MALAT1. This study reveals that MALAT1 is a potential biomarker for tumor growth and metastasis, as well as a promising therapeutic target in ovarian cancer, facilitating further ovarian cancer research.

Abstract
OBJECTIVE To investigate the clinical correlation between the manifestations of neuropsychiatric lupus (NPSLE) and brain magnetic resonance imaging (MRI). METHODS Retrospective analysis of 65 neuropsychiatric lupus patients with brain MRI and clinical data from Peking University Third Hospital from January 2006 to October 2016, which was classified by rheumatologist, neurologists, and radiologists based on their brain MRI findings. The correlation between brain MRI findings and clinical manifestations was analyzed. RESULTS The characteristics of the brain MRI of the 65 patients were divided into 6 categories: 16 cases (25%) with demyelination in the white matter, 15 cases (23%) with cerebrovascular disease, including 4 cases (6%) with large vascular disease and 11 cases (17%) with small vessel disease, 4 cases (6%) with inflammation, 4 cases (6%) with edema, 13 cases (20%) with multiple manifestation coexistence, and 13 cases (20%) without any abnormality. Except for 4 cases of brain MRI with edema, the clinical manifestations were only epileptic seizures, other patients had complex and diverse clinical manifestations, including epileptic seizures, lupus-like headaches, mental symptoms, blurred vision, peripheral neuropathy and disturbance of consciousness. The incidence of epileptic seizures in patients with edema of MRI is significantly higher than that of other patients, and the therapeutic response time is the shortest. CONCLUSION Multidisciplinary collaboration divides the MRI findings of neuropsychiatric lupus patients into six categories. This classification method helps clinicians to predict and intervene early possible neuropsychiatric symptoms to guide clinical treatment.

Abstract
In this study, we reported a case of progressive pseudorheumatoid dysplasia in Peking University Third Hospital. A 56-year-old male patient presented with hip joint pain for more than 40 years and multiple joints pain with limitation of movements of these joints for 28 years. This patient suffered from joint pain and impaired range of motion of the hip, knee, elbow and shoulder gradually, associated with difficulty in walking and inability to take care of himself. He was diagnosed with "femoral head necrosis" or "ankylosing spondylitis" in local hospitals, but the treatment of nonsteroidal antiinflammatory drugs (NSAIDs) and sulfasalazine was not effective. Up to the age of 14, the patient displayed normal physical development, with the highest height was about 158 cm, according to the patient recall. However, his height was 153 cm at present. There was no history of similar illness in any family member. Physical examinations descried limitation of movement of almost all joints. Enlargement and flexion deformity of the proximal interphalangeal (PIP) joints of the hands resulted in the claw hand appearance. Limited abduction and internal and external rotation of the shoulder and hip could be find. He had normal laboratory findings for blood routine test, biochemical indexes and acute phase reactants such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Furthermore, HLA-B27 and autoimmune antibodies such as rheumatoid factor (RF), anti-cyclic citrullinated peptide (anti-CCP) antibody and antinuclear antibody (ANA) were all negative. X-ray of the hip showed loss of the joint space and irregularities of the femoral head, both femoral head were flattened, it could be see hyperplasia, osteophytes, bilateral femoral neck thicken, neck dry angle turned smaller. The radiological findings of the spinal vertebra indicated kyphosis deformity, narrowing of the intervertebral discs, vertebral syndesmophytes and flattening of the vertebra. However, there was no clues of bone marrow edema in the lumbar MRI. At last, genetic testing for the Wnt1-inducible signaling pathway protein 3 (WISP3) gene was done and indicated compound heterozygous mutations: 756C>G and c.866dupA. These two mutations were derived from the patient's mother and father (the patient's parents each had a heterozygous mutation). Two exons of the WISP3 gene had nucleotide changes leading to amino acid mutations. According to the patient's history, symptoms, physical examinations, radiological findings and genetic testing, the final definitive diagnosis was progressive pseudorheumatic dysplasia.

Abstract
PURPOSE The diagnosis of polycystic ovary syndrome (PCOS) is based on a combination of various clinical phenotypes in each patient. However, insulin resistance (IR) and dysmetabolism are not included in the diagnostic criteria of PCOS. Therefore, the definition of PCOS is controversial. The objective of this study is to investigate whether some PCOS phenotypes can be predicted by a circulating biomarker related to IR and metabolic dysfunction in PCOS women. METHODS One hundred and seventeen women with PCOS and 95 healthy women were recruited for this study. All individuals were assessed by the phenotypic and metabolic characteristics related to PCOS. A euglycemic-hyperinsulinemic clamp was performed to assess insulin sensitivity. Circulating irisin concentrations were determined with ELISA. RESULTS In our PCOS cohort, 65.8% of individuals were found to have hyperandrogenism. 83.8% had chronic oligoanovulation, and 80.3% of subjects showed polycystic ovaries. According to the diagnostic criteria of PCOS, 30.8% of PCOS subjects were diagnosed with the classic phenotype. In addition, 65.8% of PCOS women had insulin resistance. Serum irisin levels were significantly higher in PCOS women compared with healthy women. However, PCOS women with a normoandrogenic phenotype had similar circulating irisin levels as healthy women. PCOS women with the normoandrogenic phenotype had a low homeostasis model assessment of insulin resistance (HOMA-IR) and higher M-values than PCOS women with other phenotypes. Circulating irisin levels were associated with hyperandrogenism, but not with oligoanovulation or PCO morphology. CONCLUSIONS Circulating irisin may allow physicians to establish which women merit screening by a biomarker for PCOS.

Abstract
Objective: To investigate the relationship between thrombolysis in myocardial infarction risk index(TRI) and the severity of coronary artery lesions and long-term outcome in acute myocardial infarction(AMI) patients undergoing percutaneous coronary intervention(PCI). Methods: A total of 1 663 consecutive AMI patients undergoing PCI between January and December 2013 in Fuwai hospital were prospectively included in this study. The severity of coronary artery lesions was evaluated using the SYNTAX score. Receiver operating characteristic(ROC) curve was used to analyze the optimal cut-off value of TRI on predicting all-cause mortality at 2 years after PCI.The patients were divided into 2 groups based on the optimal cut-off value of TRI:high TRI group (TRI ≥ 23.05, 465 cases) and low TRI group(TRI<23.05, 1 198 cases). Multivariate logistic regression analyses were used for determining the relationship between TRI and SYNTAX scores≥33. A multivariate Cox regression analyses was used to identify the influence factors of long-term outcome after PCI. Results: SYNTAX score was higher in high TRI group than in low TRI group (13.00(7.00, 20.50) vs.10.25(7.00, 17.00), P<0.001). TRI was independently associated with SYNTAX score ≥ 33 (OR=1.09,95% CI 1.03-1.16, P=0.004). After the 2 years follow-up, rates of all-cause death (4.1% (19/465) vs. 0.3% (4/1 198) , P<0.001), cardiac death (2.6% (12/465) vs. 0.2% (2/1 198) , P< 0.001) and stent thrombosis (1.7% (8/465) vs. 0.5% (6/1 198) , P=0.015) were all significantly higher in high TRI group than in low TRI group. Multivariate Cox regression analyses showed that TRI≥ 23.05 was an independent risk factor of all-cause death (HR=5.22, 95%CI 1.63-16.72, P=0.005), cardiac death (HR=8.48, 95%CI 1.75-41.07, P=0.008) and stent thrombosis(HR=3.87, 95%CI 1.32-11.41, P=0.014) at 2 years after PCI in AMI patients, but which was not the independent risk factor of major adverse cardiovascular and cerebrovascular events (HR=0.96, 95%CI 0.69-1.36, P=0.834) .The area under ROC curve of TRI ≥ 23.05 on predicting 2 years all-cause mortality in AMI patients undergoing PCI was 0.803(95%CI 0.711-0.894, P<0.001). Conclusions: TRI is independently associated with SYNTAX score ≥ 33. TRI is also an independent risk factor of 2 years all-cause death, cardiac death and stent thrombosis in AMI patients undergoing PCI.

Abstract
Improvements in living standards have resulted in consumers having higher expectations for chicken meat quality. This is particularly true in Asia, where there is high consumer preference for local breeds. Nothing is presently known about the effectiveness of using genomic selection (GS) strategies in chickens to genetically improve meat quality traits that cannot be measured in living potential parents. In this study, 724 Beijing-You chickens were used as a training population; all were genotyped using Illumina 60K SNP chips, and intramuscular fat content in breast muscle (IMFbr ) was measured. Birds in the GS line were selected based on genomic estimated breeding values, IMFbr being the sole trait. Genetic progress in one generation was compared to that from conventional family-based selection, and both were evaluated against random-bred controls. Results showed that relative to the random-bred controls, IMF percentage was improved 9.62% using GS, comparable to the 10.38% improvement using family-based selection. We quantified the effectiveness of GS when applied to a meat quality trait with low heritability in chickens. We plan to introduce custom SNP chips, appropriate for native chicken breeds in China, to assist in applying GS in local breeding and accelerate genetic gain.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Because of the recent increase in type 2 diabetes and the need for complementary treatments in remote communities in many parts of the world, we undertook a study of treatments for diabetic symptoms used by traditional Q'eqchi' Maya healers of Belize. We used quantitative ethnobotany to rank culturally important taxa and subsequent pharmacological and phytochemical studies to assess bioactivity. MATERIALS AND METHODS Antidiabetic plants identified in field interviews with traditional healers were ranked by syndromic importance value (SIV) based on 15 symptoms of diabetes. Species ranked with high SIV were tested in an assay relevant to many diabetes complications, the advanced glycation endproduct (AGE) inhibition assay. Active principles were identified by phytochemical analysis and bioassay. RESULTS We collected over 70 plant species having a promising SIV score. The plants represented a broad range of neotropical taxa. Selected Q'eqchi' antidiabetic plants with high SIV were collected in bulk and tested in the advanced glycation endproduct (AGE) inhibition assay. All plant extracts showed AGE inhibition and the half maximal inhibitory concentration (IC50) ranged from 40.8 to 733 µg/mL, while the most active species was Tynanthus guatemalensis Donn (Bignoniaceae). A linear regression showed a significant relationship between 1/ IC50 and SIV. Phytochemical analysis revealed the presence of verbascoside, as a major component and active principle of the T guatemalensis which had an IC50 = 5.1 µg/mL, comparable to the positive control quercetin. CONCLUSION The results reveal a rich botanical tradition of antidiabetic symptom treatments among the Q'eqchi'. Study of highly ranked plants revealed their activity in AGE inhibition correlated with SIV. T. guatemalensis was identified as a promising species for further evaluation and local use.
