Abstract
Objective: To detect the red blood cell lifespan in patients with polycythemia vera (PV), and explore the influencing factors. Methods: From February 2017 to December 2018, 27 patients with PV at Blood Diseases Hospital, Chinese Academy of Medical Science and 18 normal controls were recruited. Red blood cell lifespan was detected by endogenous carbon monoxide (CO) breath test. The related factors were analyzed. Results: The average red blood cell lifespan of 27 PV patients was 80 (range, 35-120) days (d), which was significantly shorter than that of the normal controls [110.5(69-166) d, P<0.05], namely 35.3 d shorter. The red blood cell lifespan of ten newly diagnosed patients and 17 patients who were treated with hydroxyurea and/or interferon were 98 (35-117) d and 69 (45-120) d, respectively, which were both shorter than that of the normal control (P=0.010, 0.000). Correlation analysis showed that red blood cell lifespan of patients with newly diagnosed PV was associated with JAK2 mutation allele burden (r=0.900, P=0.037), peripheral blood lymphocyte count (r=-0.742, P=0.014) and the level of serum vitamin B(12) (r=-0.821, P=0.023). Conclusion: The lifespan of red blood cells in patients with PV is about one-third shorter than normal, and is related to JAK2 mutation allele burden, absolute lymphocyte count, and serum vitamin B(12) level.

Abstract
OBJECTIVE Evidence suggested that deficiency of autophagy is involved in the pathogenesis of diabetic nephropathy (DN). However, some recent studies have also shown that autophagy is activated in renal cells under diabetic conditions. In this review, we discuss whether autophagy is inactivated in renal cells in DN as well as the therapeutic potential of autophagy for treating DN, in order to aid future investigation in this field. MATERIALS AND METHODS Relevant information, original research articles and reviews, were gathered primarily through a search in PubMed and Cochrane database. The activity and role of autophagy, as well as the relevant signaling pathways, were analyzed in different intrinsic renal cells, including podocyte, renal tubular epithelial cell, glomerular mesangial and endothelial cells. RESULTS The upstream of autophagic pathway, but not whole pathway, was predominately studied in these intrinsic renal cells, such as the induction of autophagy, an amount of autophagic vacuoles and so on. In most cases, autophagic inactivation occurred, which is an important mechanism underlying DN progression. Targeting the autophagic pathway to activate autophagy activity might have renoprotective effect. However, autophagic activation was also found in a few studies, in which there was a debate on the role of activated autophagy: mounting an adaptive response or leading to autophagic apoptosis. CONCLUSIONS The downstream of autophagic pathway, including the degradation of autophagic vacuoles, and lysosomal function, should be well studied to clarify the activity and role of autophagy in the progression of DN. Autophagy activation is likely a potential therapy for combatting DN.

Abstract
OBJECTIVES China is currently facing an unprecedented complex health demand from a rapidly aging population. Based on multidimensional health, this study aimed to identify heterogeneous latent health classes for older Chinese people, and assess regional disparities and associated sociodemographic factors. STUDY DESIGN Chinese Longitudinal Healthy Longevity Survey in 2014 was adopted. METHODS For 2886 participants aged 65 years and more without missing health indicators in physical, psychological, and social dimensions, latent class analysis was used to identify heterogeneous health. For 2128 participants with complete information, logistic regressions were used to examine how regional divisions and sociodemographic factors impact each identified class. RESULTS Four classes were identified and labeled as 'Lacking Socialization' (17.4%), 'High Comorbidity' (13.7%), 'Functional Impairment' (7.1%), and 'Relative Health' (61.8%). When the Relative Health class was the reference, the likelihoods of the High Comorbidity and Functional Impairment classes were higher for older adults in eastern and central regions than in western regions. Those in eastern regions also tended to be in the Lacking Socialization class than in western regions. The effects of regional divisions on the different classes were significantly impacted by sociodemographic characteristics. CONCLUSIONS Four health classes identified by multidimensional health have enhanced our understanding of heterogeneity among older Chinese people. By examining regional disparities in China, our study provided evidence for health policies addressing the issue of aging with respect to regional disparities.

Abstract
Objective: Previous cross-sectional studies suggested that elevated levels of total cholesterol content of erythrocyte membrane (CEM) could significantly increase the risk of acute coronary syndrome (ACS). The purpose of the present study was to assess the predictive value of baseline CEM levels for the risk of clinical endpoint events in patients with ACS through prospective follow-up studies. Methods: This study is a prospective follow-up study, which consisted of 859 patients with first ACS (698 patients with unstable angina pectoris and 161 patients with acute myocardial infarction), diagnosed and hospitalized in the First and Second Affiliated Hospital of Anhui Medical University. The routine blood lipid levels and CEM were measured. Patients were divided into two groups according to the median of baseline CEM: CEM≤131.56 μg/mg group (n=430) and CEM>131.56 μg/mg group (n=429). Patients were followed up at 6 months interval. The clinical endpoints were nonfatal myocardial infarction, nonfatal stroke, all-cause mortality, all-cause mortality, heart failure requiring hospitalization, and coronary artery revascularization. Kaplan-Meier curve analysis and Cox proportional hazard model were used to analyze the impact of elevated CEM on the occurrence of clinical end-point events. HR values and 95%CI of each variable were obtained. Cox regression analysis of all-cause mortality was performed according to whether patients had risk factors for coronary heart disease (hypertension, diabetes, smoking and elevated LDL-C) and whether they were treated with PCI. Results: The follow-up time was 1 640 (1 380, 2 189) days. Cox analysis after adjustment showed that an elevated baseline of CEM (>131.56 μg/mg) was associated with an increased risk of all-cause mortality (HR=1.690, 95%CI 1.041-2.742, P=0.034), but had no significant predictive effect on the other clinical endpoints. Subgroup analysis showed that elevated baseline CEM levels in ACS patients with LDL-C>1.8 mmol/L (HR=1.687, 95%CI 1.026-2.774, P=0.039), receiving in-hospital PCI (HR=2.365, 95%CI 1.054-5.307, P=0.037), or male (HR=1.794, 95%CI 1.010-3.186, P=0.046) were associated with an increased risk of all-cause mortality. Conclusion: The results showed that elevated CEM levels can increase the risk of all-cause mortality in ACS patients.

Abstract
The assay was used in HIV/AIDS surveillance sentinel sites to identify recent HIV-1 infection, to estimate HIV-1 incidence and understand the epidemic trends among men who have sex with men during 2011-2015. During 2011-2015, the HIV-1 incidence of men who have sex with men was 5.16%(95%CI: 4.65%-5.66%) in Sichuan Province. According to<Pilot study on classification criteria of AIDS epidemic in China>, a total of 9 cities had been divided into two type of regions: the first type(the proportion of live HIV/AIDS accounts for more than 0.1% of the permanent population, and the number of live HIV/AIDS has reached 500 cases and above) and the second type(the proportion of live HIV/AIDS accounts for 0.03% to 0.100% of the permanent population, and the number of live HIV/AIDS has reached 100-500 cases). During 2011-2015, the HIV-1 incidence of the second type was 4.24% (95%CI: 3.72%-4.76%). The HIV-1 incidence of men who have sex with men was at a high level. The spread of HIV-1 to the second region was possible.

Abstract
AIM To explore the function and mechanisms of NLRP6 (NOD-, LRR- and pyrin domain-containing 6) in the inflammatory response of human periodontal ligament cells (HPDLCs). METHODOLOGY Tissues associated with apical periodontitis were obtained from three patients who underwent endodontic microsurgery. The expression of NLRP6 in 3 human apical periodontitis tissues and HPDLCs was examined by immunohistochemistry and immunofluorescence, respectively. The expressions of NLRP6, Phospho(p)- p65, p65, IκB-α, p- IκB-α, ERK, p- ERK, NLRP3, Pro interleukin (IL)-1β, Pro caspase-1 and apoptosis-associated speck-like protein containing a CARD (ASC) were examined by western blot. The gene expression and secretion of proinflammatory cytokines were detected using quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay. Data were analysed statistically with independent sample t-tests. RESULTS NLRP6 was expressed in inflammatory periapical tissues and HPDLCs. Lipopolysaccharide (LPS) from Escherichia coli induced NLRP6 in HPDLCs (P < 0.05). After silencing NLRP6, E. coli LPS-induced activation of NF-κB and ERK signalling was enhanced, which was also accompanied by elevated levels of IL-6 and tumour necrosis factor-α (TNF-α) (P < 0.05). Moreover, knockdown of NLRP6 led to up-regulation of NLRP3, Pro IL-1β and Pro caspase-1 (P < 0.05), whereas down-regulation of ASC (P < 0.05), which may contribute to unchanged levels of IL-1β in HPDLCs inflammation. CONCLUSION NLRP6 was functionally expressed in inflamed periapical tissues and HPDLCs. NLRP6 negatively regulated the production of IL-6 and TNF-α in HPDLCs inflammation by inhibiting NF-κB and ERK signal pathways.

Abstract
Currently, there exists an urgent need to investigate the anti-cancer effects of lidocaine on gastric cancer cells. The purpose of the present study was to evaluate the anti-tumor effects and the underlying mechanisms of lidocaine in gastric cancer cells. Our results indicated that lidocaine significantly suppressed proliferation, migration and invasion and induced apoptosis in a dose-dependently manner in human gastric cancer cells. In addition, our data shown that the expression of Bcl-2 was decreased and the level of Bax was increased by lidocaine treatment. Furthermore, we found that lidocaine altered the protein expression of the MAPK pathway. p-p38 was also increased simultaneously, while the level of p38 was not changed. In summary, lidocaine has a prominent anti-tumor activity on gastric cancer cells and is a promising therapeutic agent for the treatment of gastric cancer (Fig. 4, Ref. 32). Keywords: lidocaine, gastric cancer cells, anti-tumor effect, MAPK pathway.

Abstract
OBJECTIVES China is facing an escalating demand of healthcare services from the middle-aged and elderly. Compared with the traditional view of health on symptoms and diseases, this study aimed to assess the heterogeneous health profiles of middle-aged and elderly Chinese by a person-centered approach. Furthermore, this study examined the effects of health profiles and associated factors on healthcare utilization within the context of China's multiple health insurance schemes. STUDY DESIGN The study used the 2015 data of China Health and Retirement Longitudinal Study, a nationwide population-based sample of people aged 45 years and older. METHODS Latent class analysis (LCA) was adopted to identify the heterogeneous health profiles. Two-part models were adopted to assess the effects of associated factors on healthcare utilization. RESULTS Among 15,250 Chinese aged 45 years and older, six heterogeneous health profiles were identified and labeled as 'Quite Healthy', 'Relatively Healthy', 'Comprehensive Comorbidities', 'Functional Impairment', 'Severe Disability', and 'Relatively Frail'. The Relatively Frail profile was the heaviest healthcare user. The Severe Disability profile took the least use of outpatient services but had relatively high utilization of inpatient services and outpatient expenditure. The Comprehensive Comorbidities profile tended to have the smallest effect on the frequency of visits for both inpatient and outpatient services, but its effect on outpatient expenditure was high. After controlling for health profiles, the significant effects of different health insurance programs on healthcare utilization were discussed. CONCLUSIONS Introducing health profiles by the person-centered approach of LCA has provided a holistic understanding of complex healthcare demands for middle-aged and elderly Chinese. It is valuable for policy makers to improve healthcare resource allocation targeted for the middle-aged and elderly.

Abstract
Objective: To evaluate the therapeutic efficacy and safety of immunosuppressive therapy (IST) combined with recombinant human thrombopoietin (rhTPO) for severe aplastic anemia (SAA) in pediatric patients. Method: A retrospective case-control study was conducted and the clinical data of 45 pediatric patients with de novo SAA admitted to the Anemia Diagnosis and Treatment Center of Chinese Academy of Medical Sciences & Blood Disease Hospital during the period from December 2009 to December 2014 were analyzed. Among them, 15 patients were treated with the regimen of IST together with rhTPO and 30 patients were given IST treatment only. The variation characteristics of the peripheral blood routine as well as the transfusion of blood products was dynamically observed, and the therapeutic efficacy was assessed respectively after 3, 6 and 12 months after the treatment. In the meantime, adverse effects related to rhTPO application were recorded. Thereafter, the statistics of the two groups were compared by non-parametric rank sum test. Result: Among 45 pediatric patients, there were 26 male and 19 female, and the median age was 11 years (6-14). The number of patients received good hematological response(complete remission (CR) plus good partial response (GPR)) in the combinatory group versus vs. the IST group was 6 vs. 3 patients (χ(2)=3.906, P=0.048) at the 3rd month, 7 vs. 7 patients (χ(2)=1.568, P=0.210) at the 6th month, and 13 vs. 14 patients (χ(2)=6.667, P=0.01) at the 12th month respectively. For those achieved good hematological response at the 3rd month, the amount of platelets transfusion and red blood cells transfusion of the combined group were both less than that of the IST group during the period from the 10th to the 12th weeks (platelets transfusion: 1.4 U vs. 2.9 U, t=-3.523, P=0.002; red blood cells transfusion: 0.8 U vs. 2.6 U, t=-2.392, P=0.026). No serious adverse effect related to rhTPO application was observed in the IST combined with rhTPO group. Conclusion: Application of rhTPO can improve the short-term therapeutic efficacy of IST for pediatric SAA, alleviate transfusion dependence, and has a good safety profile.

Abstract
BACKGROUND While increased levels of circulating inflammatory cytokines in chronologically aged humans have been linked to the development of ageing-associated chronic disorders (e.g., cardiovascular disease, type II diabetes, osteoporosis and Alzheimer's disease), approaches that reduce circulating cytokines are not yet available. In chronologically aged mice, we recently demonstrated that epidermal dysfunction largely accounts for age-associated elevations in circulating cytokine levels, and that improving epidermal function reduced circulating cytokine levels. OBJECTIVE We performed a pilot study to determine whether improving epidermal function reduces circulating pro-inflammatory cytokine levels in aged humans. METHODS Thirty-three aged humans were topically treated twice-daily for 30 days, with ≈ 3 mL of an emollient, previously shown to improve epidermal function, while untreated, aged humans and a cohort of young volunteers served as controls. Changes in epidermal function and levels of three key, age-related, plasma cytokines (IL-1β, IL-6 and TNFα) were measured at baseline and after treatment, using Luminex 200™ system. RESULTS We also found significantly higher baseline levels of IL-1β, IL-6 and TNFα in aged vs. young humans (P < 0.001), as previously reported. Topical applications of the barrier repair emollient significantly enhanced epidermal permeability barrier function (P < 0.01) and stratum corneum hydration (P < 0.05). In parallel, circulating levels of IL-1β and IL-6 normalized, while TNFα levels declined substantially. CONCLUSION The results of this preliminary study suggest that a larger clinical trial should be performed to confirm whether improving epidermal function also can reduce circulating pro-inflammatory cytokine levels in aged humans, while also possibly attenuating the downstream development of chronic inflammatory disorders in the aged humans.

Abstract
Objective: To investigate the effect of different cryoablation time on tracheal traumatic granulation formation and its mechanism. Methods: A total of 32 rabbits were randomly assigned into four groups (A-D). Group A underwent tracheotomy alone. Group B, C and D received intra-tracheal brush rubbing to establish airway granulation model. Group C and D underwent 30 s and 2-minute cryoablation respectively. Tracheal specimens of all groups were collected to examine pathological changes using HE staining. Levels of transforming growth factor beta 1 (TGF-β(1)) and CD34 in tracheal granulation were evaluated using immunohistochemistry (IHC) and real-time quantitative reverse transcription polymerase chain reaction (RT-qCR). Results: Tracheal lumens of group A were smooth without granulation. While the growth of granulation and luminal stenosis were most severe in Group B, followed by Group D and C. Submucosa thickness of Group B was largest as compared with other groups (0.20±0.07, 0.77±0.28, 0.44±0.13 and 0.55±0.18 mm for Group A to D, respectively. P<0.05). And the submucosa layer of Group C was thinner than Group D (P<0.05). The expression and transcription levels of TGF-β(1) of trachea were highest in Group B as detected by IHC and RT-qPCR (P<0.05), followed by Group D and C (IHC: 0.48±0.01 vs 0.43±0.01, P<0.05; RT-qPCR: 12.61±2.14 vs 2.38±0.10, P<0.05). Both protein and mRNA levels of CD34 were highest in Group B as detected by IHC and RT-qPCR (P<0.05). Tracheal mRNA levels of CD34 were more abundant in Group D than Group C (4.92±0.90 vs 2.09±0.10, P<0.05), while no significant difference was found between groups regarding protein levels measured by IHC. Conclusions: Cryoablation could alleviate the hyperplasia of tracheal traumatic granulation, possibly due to the inhibition of TGF-β(1) and CD34 expression. The effect of 30 s cryoablation for tracheal traumatic granulation is better.

Abstract
While therapeutic approaches for psoriasis are widely available, preventive regimens are lacking. We aimed to determine whether improvements in epidermal function could prevent psoriasis relapse. Two self-controlled cohort studies were designed, enrolling two cohorts of patients with psoriasis (n = 30 and n = 60) to be treated topically with an in-house-prepared emollient or ATOPALM® cream applied twice daily to one forearm for 20 and 30 days, respectively, while the same sites on the contralateral arm served as the untreated control. Epidermal function on both arms was assessed prior to and at the end of the trials. Delayed relapse on the treated arm was seen in 54.5% and 71% of patients in the first and second cohort, respectively. The time of psoriatic relapse correlated with the extent of abnormalities in baseline epidermal function. These results suggest that improvements in epidermal function with topical emollients can prevent/attenuate the development of psoriasis.

Abstract
目的 分析极重型/重型再生障碍性贫血(V/SAA)患者一线免疫抑制治疗(IST)迟发血液学反应特征,探讨难治性V/SAA尽早二次治疗的合理性。 方法 回顾性分析一线接受IST的533例V/SAA患者临床资料,定义IST后6个月内获得血液学反应为应时反应,定义6~12个月获得血液学反应为迟发反应,观察迟发反应的发生率、血液学反应质量及其影响因素。 结果 533例患者中,45例(8.44%)获得迟发反应,占未获得应时反应且继续接受环孢素A治疗患者的29.03%(45/155)。至IST后12个月及随访结束时迟发反应组血液学反应质量均劣于应时反应组(χ2=62.616,P<0.001和χ2= 6.299,P=0.043)。迟发反应组VSAA患者比例高于应时反应组(57.8%对38.3%,P=0.013),外周血网织红细胞(ARC)比例、ARC计数以及ANC更低,多因素分析显示治疗前ARC<10×109/L的患者获得应时反应的机会明显减少[OR=3.641(95% CI 1.1718~7.719),P=0.001];未发现独立预测IST后6个月无效患者获得迟发血液学反应的因素。6个月未获血液学反应患者5年总生存率为76.50%(95% CI 71.6%~81.4%)、无事件生存率为29.10%(95% CI 25.2%~33.0%),均显著低于应时反应组患者的97.6%(95% CI 96.6%~98.6%)、84.0%(95% CI 81.1%~86.9%)(P值均<0.001)。 结论 V/SAA患者IST获得迟发血液学反应难以预测,比例较小,疗效质量相对较差。难治性V/SAA患者尽早进行挽救治疗是合理的。

Abstract
Objective: To investigate the expression of Fermintin family homologous protein 2 (FERMT2) in non-small cell lung cancer and its clinical significance. Methods: Seventy-two patients with non-small cell lung cancer were collected at Xinxiang Central Hospital, Henan Province, from January 2015 to January 2017.There were 48 male and 24 female patients, the age ranged from 37 to 78 years (mean 58 years). The expression of FERMT2 in tumor samples and para-cancerous tissues were detected by immunohistochemistry. Protein and mRNA expression of FERMT2 were detected by Western blot and real-time fluorescence quantitative PCR, respectively. Western blot method was also used to detect integrin-related protein expression, including integrin beta 1 (CD29), vascular cell adhesion molecule (VCAM1), and mobile related protein-1 (MRP1). Results: Immunohistochemistry showed that the positive rates of FERMT2 expression were 81.9%(59/72)in carcinoma tissue and 15.4%(11/72) in para-cancerous tissues, and the difference was statistically significant (P<0.01). Positive FERMT2 expression was different in tumors at different tumor stages: 11/17 at stage Ⅰ, 16/20(80.0%)at stage Ⅱ, 17/20(85.0%)at stage Ⅲ, and 15/15 at stage Ⅳ, and there was a significant difference between each stage (P<0.01). By real-time PCR and Western blot, the expression of FERMT2 in non-small cell lung cancer tissues was significantly higher than that of para-cancerous tissue (P<0.01). The expression levels of integrin related proteins (integrin β1, VCAM1 and MRP1) in tumor tissues were significantly higher than those in para-cancerous tissues, and positively correlated with the expression of FERMT2 (r=0.531, P<0.01; r=0.483, P<0.01; r=0.612, P<0.01). Conclusions: FERMT2 is highly expressed in non-small cell lung carcinomas. Its expression is closely correlated with the tumor clinical stage. It is hypothesized that FERMT2 may promote tumor metastasis through interactions with integrin-like protein.

Objective:To investigate interventional effect of APP on prognosis in patients with chronic rhinosinusitis after endoscopic sinus surgery. Method:One hundred and forty-four chronic rhinosinusitis patients in our hospital were divided into observation group and control group randomly; observation group had 71 patients, and control group had 73 patients. The control group was treated with standard discharge instruction. In addition to standard discharge instruction, observation group was followed up and directed by using of APP. Two groups' VAS scores and Lund-Kennedy scores were compared in admission time, and 6 months after discharge. Result:There was no significant difference in the Lund-Kennedy scores and VAS scores between the two groups in admission time. However, 6 months after discharge, Lund-Kennedy scores and VAS scores in observation group were obviously lower than control group(P< 0.05). Conclusion:The use of healthy APP can significantly promote patients with chronic rhinosinusitis recovery and re-visit after endoscopic sinus surgery.

Abstract
Objective To establish the primary cat intestinal epithelial cells (IECs) culture methods and construct the cDNA library for the following yeast two-hybrid experiment, so as to screen the virulence interaction factors among the final host. Methods The primary cat IECs were cultured by the tissue cultivation and combined digestion with collagenase XI and dispase I separately. Then the cat IECs cultured was identified with the morphological observation and cyto-keratin detection, by using goat anti-cyto-keratin monoclonal antibodies. The mRNA of cat IECs was isolated and used as the template to synthesize the first strand cDNA by SMART™ technology, and then the double-strand cDNAs were acquired by LD-PCR, which were subsequently cloned into the plasmid PGADT7-Rec to construct yeast two-hybrid cDNA library in the yeast strain Y187 by homologous recombination. Matchmaker™ Insert Check PCR was used to detect the size distribution of cDNA fragments after the capacity calculation of the cDNA library. Results The comparison of the two cultivation methods indicated that the combined digestion of collagenase XI and dispase I was more effective than the tissue cultivation. The cat IECs system of continuous culture was established and the cat IECs with high purity were harvested for constructing the yeast two-hybrid cDNA library. The library contained 1.1×106 independent clones. The titer was 2.8×109 cfu/ml. The size of inserted fragments was among 0.5-2.0 kb. Conclusion The yeast two-hybrid cDNA library of cat IECs meets the requirements of further screen research, and this study lays the foundation of screening the Toxoplasma gondii virulence interaction factors among the cDNA libraries of its final hosts.

Abstract
BACKGROUND Measurements of transepidermal water loss (TEWL) and stratum corneum (SC) hydration are important for assessing epidermal functions. However, the availability of reliable and user-friendly devices, which can simultaneously measure both TEWL and SC hydration and can allow health providers to remotely access data in time, is limited. MATERIALS AND METHODS GPSkin Barrier® was compared with MPA5 system in the measurements of TEWL and SC hydration on the cheek, the dorsal hand, and the forearm in 200 normal volunteers, including 126 females and 74 males, aged 1-78 years with an average age of 45.24 ± 1.04 years. Correlation of data measured with MPA5 system and GPSkin Barrier® was determined. RESULTS Levels of both TEWL and SC hydration measured with the Barrie GPSkin Barrier® were lower than that with MPA5 system on all 3 body sites except for hydration on the cheek. The levels of both TEWL and SC hydration measured with GpSkin Barrier® were correlated well with that measured with MPA5 system on all 3 body sites CONCLUSIONS: GPSkin Barrier® is a reliable, affordable, and versatile device for assessing epidermal permeability barrier function and SC hydration.

Abstract
OBJECTIVE To investigate the effect of add-on exenatide to insulin on glycemic excursion and the counter-regulatory hormone in response to hypoglycemia in patients with type 1 diabetes mellitus (T1DM). METHODS 30 patients with T1DM were recruited and randomly assigned to exenatide + insulin-treated group (group 1, n = 15) or insulin-only-treated group (group 2, n = 15) for 4 weeks. All patients had continuous glucose monitor system (CGMS) applied at before (week-0) and after (week-4) treatment to evaluate the glycemic variability. All patients had an arginine-stimulated test at before and after treatment. Six patients from each group also had hypoglycemic clamp test to assess counter-regulatory hormone level. RESULTS Patients in the exenatide group had significant reductions in body weight, body mass index (BMI), total insulin dose, bolus insulin dose, fructosamine, and glycemic excursion after 4 weeks' treatment. Compared with patients in group 2, the mean amplitude of glycemic excursion (MAGE) and coefficient of variation (CV) of exenatide group decreased significantly. Similarly, a significant decrease of glucagon (GLC) in the arginine-stimulated test was found in group 1. No significant changes of GLC, growth hormone (GH), cortisol (COR), epinephrine (E), and norepinephrine (NE) were found in both groups during hypoglycemia clamp test. However, patients who had residual islet function in group 1 showed an upward trend of basic C-peptide (C-P) and GLC during the hypoglycemia period. CONCLUSION Although exenatide could inhibit glucagon secretion during euglycemia or hyperglycemia in patients with T1DM, it has no effect on GLC and counter-regulatory hormones during hypoglycemia clamp in patients with no functional residual islet test.

Abstract
OBJECTIVE Talaromyces marneffei is an opportunistic infection with high morbidity among human immunodeficiency virus (HIV)/AIDS patients in Southeast Asia and southern China. Its effects on mortality in HIV/AIDS patients has not been clearly elucidated. METHODS We conducted a retrospective cohort study of hospitalized HIV-infected individuals at the Fourth People's Hospital of Nanning, Guangxi, China during 2012-2015. Kaplan-Meier analyses were used to calculate the cumulative mortality. Cox proportional hazard models and 1:1 propensity score matching (PSM) were used to evaluate the effects of T. marneffei infection on mortality of HIV/AIDS patients. RESULTS In total, 6791 HIV/AIDS patients were included, 1093 of them (16.1%) with documented T. marneffei co-infection. The mortality of T. marneffei-infected patients (25.0 per 100 person-months, 95% CI 21.5-26.7) was the highest among all AIDS-associated complications and was significantly higher than that of T. marneffei-uninfected HIV/AIDS patients (13.8 per 100 person-months, 95% CI 12.5-15.1; adjusted hazard ratio (AHR) 1.80, 95% CI 1.48-2.16). The results using PSM were similar (AHR 4.52 95% CI 2.43-8.42). The mortality of T. marneffei-infected patients was also significantly higher than that of patients without any complications. When stratified by demographic characteristics, T. marneffei infection has higher mortality risk in all stratifications. Co-infection with T. marneffei carries a higher mortality risk in patients at any CD4+ T-cell count. CONCLUSIONS Talaromyces marneffei infection is commonly found in hospitalized HIV/AIDS patients in southern China and was associated with a higher mortality rate than most HIV-associated complications. These results highlight the need for improved diagnosis, treatment and prevention of infection by this neglected fungal pathogen in southern China.

Abstract
Objective: Data from the HIV/AIDS surveillance sentinel sites was used to identify the recent HIV-1 infections and to estimate the HIV-1 incidence and epidemic trends among intravenous drug users (IDU), MSM, female sex workers and men attending the sexually transmitted disease clinics in Sichuan province. Methods: Specimens collected from IDUs, MSM, female sex workers and men attending the sexually transmitted disease clinics sentinel sites were confirmed as HIV-1 positive and tested with BED-CEIA. Annual HIV-1 prevalence and incidence rates were calculated and the incidence was adjusted by McNermar method. Results: A total number of 194 223 serum specimens were collected and HIV antibody tested, with 5 297 HIV-1 positive. 4 640 of the positives underwent BED-CEIA, with 749 identified as recent infections. During 2011-2015, HIV-1 incidence rates of the four types of population appeared as 5.16% (95%CI: 4.65-5.66), 0.22% (95%CI:0.16-0.28), 0.57%(95%CI: 0.45-0.69), 7.53% (95%CI: 6.06-9.01) and 0.44% (95%CI: 0.36-0.53) respectively. Significant differences were seen in the HIV-1 incidence rates. Conclusions: The HIV-1 incidence rates of IDUs from other sentinel sites in Sichuan province, female sex workers and men attending the sexually transmitted disease clinics appeared low, showing that the AIDS prevention and control activities worked effectively. However, the HIV-1 incidence of MSM was still at high level and even rising, suggesting that HIV-1 transmission between MSM and IDUs was possible.

Abstract
Abstract
Background. Yangzheng Xiaoji is a formulation of Chinese medicine and has been used in the treatment of solid cancer as an adjuvant to chemotherapy by reducing the side effects to the patient. There has been evidence to show that the medicine has a direct biological role in cancer cells. In the present study, we sought to investigate the potential effects of the medicine on breast cancer cells and in particular aimed to identify the key targets and molecular pathways contributing to the anti-cancer effect of the medicine.
Methods. Human breast cancer cell lines (BT549, BT20, MDA MB-231, MCF-7 and ZR 75-1) with varying invasiveness and receptor status were used. The soluble extract of Yangzheng Xiaoji, namely DME25 was used in the study. The effects of DME25 on the growth, toxicity and cellular migration were assessed. Signalling kinase changes were screened using kinase antibody array based array technologies. Kinases were also validated using phosphorylation based protein blotting.
Results. Of the five breast cancer cell lines tested, Yangzheng Xiaoji extract DME25 showed little cytotoxicity over a broad range of concentrations. However, DME25 were able to markedly reduce the migration of the panel of breast cancer tested, without being toxic. Triple negative cells responded in a similar fashion with other cells. It was also noted that the adhesion of these cells were also inhibited by DME25. Using a protein kinase array, it was shown that a number of kinase complexes were inhibited by the medicine, notable ones including EGFR family kinases (reduced by 35%), Janus protein kinases (JAK) (by 57%), and Ras-related C3 botulinum toxin substrate (Rac1 or CDC42 GTPase) (by 49%) and Ribosomal protein S6 kinases (RSKs) (by 52%). Given the clinical significance of RSKs in human breast cancer, we further evaluated the role of RSK and RSK inhibitors in DME mediated cell functions and have demonstrated that both in triple negative breast cancer cells and receptor positive breast cancer cell lines, DME25 was able to synergistically enhance the effect of RSK2 inhibitor, SL1010-1, on the both the cellular migration and cell growth.
Conclusion. Yangzheng Xiaoji has a broad and direct effect on the migration of breast cancer, an effect unrelated to hormone receptor status and independent of cytotoxicity. The medicine appears to target kinase pathway, particularly for the RSK kinases, suggesting an important clinical implication in the treatment of breast cancer.

Abstract
Objective: To explore the life span of red blood cells (RBC) in patients with severe/very severe aplastic anemia (SAA/VSAA). Methods: Clinical data of 128 SAA/VSAA patients from November 2016 to April 2017 were retrospectively analyzed, and 13 healthy volunteers in the same period was used as normal control. The endogenous Breath Carbon Monoxide (CO) test was used to detect the life span of RBC in SAA/VSAA patients, and the effect of immunosuppressive therapy (IST) on the life span of RBC in these patients was explored. Results: The mean life span of RBC in 51 untreated SAA/VSAA patients was (50.69±21.43) d, which was significantly shorter than that in normal controls[(111.85±31.55) d](t=-6.611, P<0.001). The mean life span of RBC in 77 patients treated with IST was (87.14±39.28) d. The mean life span of RBC in complete responses (CR), hematologic response (HR) and non-response (NR) patients were (106.15±32.12) d, (92.00±38.60) d and (50.44±21.56) d, respectively. The life span of RBC in patients with HR was significantly longer than that in newly diagnosed and NR patients (t=7.430, P<0.001; t=4.846, P=0.002), which was similar to that in the normal controls (t=-1.743,P=0.085). There was no statistical significance between CR patients and the normal controls in the mean life span of RBC (t=-0.558, P=0.579). No factor affecting the RBC life span was found in univariate logistical regression analyses in the newly diagnosed SAA/VSAA patients. The serum levels of IL-2R and IL-6 were much lower in HR patients than NR patients[IL-2R: 4.3×105 U/L vs 6.5×105 U/L, z=-2.733, P=0.006; IL-6: 2.6 (2.0-17.7) ng/L vs 6.1 (2.0-14.4) ng/L, z=-2.968, P=0.003]. Of the 51 newly diagnosed patients, 38 received IST and their 3-month curative effect was evaluated. Receiver operator characteristics (ROC) curve was used to analyze the predictive effect of RBC life span of untreated patients on the efficacy of IST before treatment. The cut-off point was 60 days with sensitivity of 37.5% and specificity of 86.4%. In 9 cases with life span of RBC>60 d before IST, 6 cases acquired HR, while in 29 cases with life span of RBC ≤ 60 d before IST, 10 cases acquired HR, the difference was not statistically significant (P=0.128). Conclusion: The life span of RBC in SAA/VSAA patients was shortened, which can be improved even recovered to the normal after IST. Elevated cytokines might play a role in the pathophysiology of the shortened RBC life span in SAA/VSAA.

Abstract
AIM To determine the clinical non-inferiority of recombinant glargine-Basalin vs glargine-Lantus, in treatment of type 2 diabetes mellitus (T2DM) using continuous glucose monitoring system (CGMS). METHODS One hundred patients with T2DM were recruited. They were either regularly taking Basalin (Basalin group) or Lantus (Lantus group) (n = 50 each). CGMS was employed to real-time monitor blood glucose profile for 4 days (from day 1 to day 5). To exclude the effect of patient background, the study design was to have a blinded crossover from glargine-Basalin to glargine-Lantus on day 3, and vice versa. 24-hour mean blood glucose (24hMBG), 24-hour standard deviation of blood glucose (24hSDBG), 24-hour mean amplitude of glycemic excursion (24hMAGE), and number of glycemic excursion (NGE) every 24 h (24hNGE) were calculated for each glargine from 100 patients. RESULTS No significant difference of 24hMBG, 24hSDBG, 24hMAGE, and 24hNGE (p > 0.05 for all) was found between Basalin and Lantus treatments. The glucose area under the curve and time when blood glucose was below 3.9 mmol/L, between 3.9 and 10.0 mmol/L, or above 10.0 mmol/L were similar between Basalin and Lantus treatment. The frequency of hypoglycemic episodes was also similar. However, the mean cost of Basalin was only 72% of Lantus's in one treatment course. CONCLUSION Glargine-Basalin is non-inferior in clinical efficacy compared to glargine-Lantus. In view of the large difference in the cost of glargine-Basalin, it would be much more cost-effective for our patients.

Abstract
BACKGROUND The value of maximum standard uptake value (SUVmax) was overlooked in current studies comparing stereotactic body radiotherapy (SBRT) versus surgery for stage I non-small cell lung cancer (NSCLC). Herein, we aimed to compare the 3-year outcomes based on patients for whom SUVmax were available, and to explore the role of SUVmax in clinical decision-making. METHODS From January 2010 to June 2016, data of eligible patients were collected. Patient variables and clinical outcomes were compared in both unmatched and matched groups using propensity score matching (PSM). Multivariate analysis was performed for predictors of poor outcome. The relationship between treatment approach and survival outcome was also evaluated in subgroup patients stratified by SUVmax level. RESULTS A total of 425 patients treated with either surgery (325) or SBRT (100) were included. Patients receiving SBRT were significantly older, had a higher level of SUVmax and were more likely to have tumor of centrally located. Multivariate analysis showed that SUVmax and tumor size were significant predictors for 3-year OS, LRC, and PFS, while better PFS was also related to peripheral tumor and surgery. The result of PSM analysis also showed that compared to SBRT, surgery could only achieve better PFS. Subgroup analysis indicated that surgery had added advantage of 3-year LRC and PFS for patients in high SUVmax group (SUVmax > 8), but not in low SUVmax group. CONCLUSIONS The study found a superior PFS after surgery while OS and LRC did not differ between SBRT and surgery. Surgery should be recommended for tumor of high SUVmax.

Abstract
The enhancer of zeste homolog 2 (EZH2) is a catalytic subunit of PRC2 (polycomb repressor complex 2). It mediates gene silencing via methyltransferase activity and is involved in the determination of cell lineage. However, the function of EZH2 and the underlying mechanisms by which it affects the differentiation of human dental pulp cell (hDPC) have remained underexplored. In this research, we found that EZH2 expression decreased during the mineralization of hDPCs, with attenuated H3K27me3 (trimethylation on lysine 27 in histone H3). Overexpression of EZH2 impaired the odontogenic differentiation of hDPCs, while EZH2 without methyltransferase activity mutation (mutation of suppressed variegation of 3 to 9, enhancer of zeste and trithorax domain, EZH2ΔSET) did not display this phenotype. In addition, siRNA knockdown studies showed that EZH2 negatively modulated hDPC differentiation in vitro and inhibited mineralized nodule formation in transplanted β-tricalcium phosphate / hDPC composites. To further investigate the underlying mechanisms, we explored the Wnt/β-catenin signaling pathway in view of the fact that previous research had documented the essential role that it plays during hDPC mineralization, as well as its links to EZH2 in other cells. We demonstrated for the first time that EZH2 depletion activated the Wnt/β-catenin signaling pathway and enhanced the accumulation of β-catenin in hDPCs. Chromatin immunoprecipitation analysis suggested that these effects are attributable to the level of the EZH2-regulated H3K27me3 on the β-catenin promoter. We conclude that EZH2 plays a negative role during the odontogenic differentiation of hDPCs. Suppression of EZH2 could promote hDPC mineralization by epigenetically regulating the expression of β-catenin and activating the Wnt canonical signaling pathway.

Abstract
BACKGROUND Psoriasis is a complex disease influenced by both genetic and environmental factors with abnormal gene expression in lesional skin. However, no studies are available on genome-scale gene expression of psoriatic lesions in the Chinese population. In addition, systematic studies on the biological pathways, pathogenicity and interaction networks of psoriasis-related genes with abnormal expression profiles require further investigation. OBJECTIVES To further explore the associated pathways in psoriasis by functional analysis and to identify the key genes by gene pathogenicity analysis. METHODS We performed RNA sequencing on 60 skin biopsy samples from patients with psoriasis and healthy controls to identify the primary differentially expressed genes in psoriatic lesional skin. We retrieved all reported psoriasis-associated genes and performed integrative analyses covering gene expression profiling, pathway analysis, gene pathogenicities and protein-protein interaction networks. RESULTS We found that internal and external stimuli may activate immunoinflammatory responses to promote the development of psoriasis. Pathways associated with infectious diseases and cancers were identified by functional and pathway analyses. The gene pathogenicity analysis revealed five key genes in psoriasis: PPARD, GATA3, TIMP3, WNT5A and PTTG1. CONCLUSIONS Our analyses showed that genes contributed to the pathogenesis of psoriasis by activating risk pathways with components abnormality in expression. We identified five potentially pathogenic genes for psoriasis that may serve as important biomarkers for the diagnosis and treatment.

Abstract
This randomized clinical trial evaluated the efficiency of maxillary infiltration anesthesia in carious teeth at two different injection sites and their impact on the laser Doppler recordings of pulpal blood flow (PBF) during a caries excavation procedure. The null hypothesis tested was that there are no differences in the efficiency of anesthesia and PBF reduction between maxillary infiltrations at the two injection sites. One hundred twenty patients were divided into three groups according to the degree of carious lesion of their maxillary left central incisors (moderate caries, deep caries, or no caries). Forty patients in each group randomly received infiltrations over the root apex of maxillary left central incisors (site X) or over the midpoint of the line connecting the root apexes of both maxillary left central and lateral incisors (site Y) using 0.9 mL 2% lidocaine with 1:100,000 adrenaline. Teeth were pulp tested at five-minute intervals after injection except for the period of cavity cutting, which was done 12 minutes after injection. The PBF changes after injection were monitored by laser Doppler flowmetry. The observation period in this study was 60 minutes. Success of anesthesia was defined as no or mild pain on cavity cutting by visual analog scale recordings. Deep caries group showed significantly higher baseline PBF ( p<0.05). All groups showed 100% success of anesthesia and similar duration time ( p>0.05). Subgroups that had the injection at site Y showed significantly less reduction of PBF ( p<0.05). Cavity-cutting procedures increased the amplitude of the PBF around the lowest value after injection. Independent of the cavity depth, carious anterior teeth anesthetized by infiltration further from the apex had significantly less reduction on the pulpal blood flow compared with teeth anesthetized by infiltration at the apex.

Abstract
To explore the therapeutic effect of curcumin (Cur) and soybean oligosaccharides (SBOS) on ulcerative colitis (UC) through testing the intestinal flora and ulcerative colitis (UC). 80 male SD rats were selected divided into four groups with 20 rats in each group: normal group, sulfasalazine (SASP) group, model group and group of curcumin plus soy oligosaccharide. All animals were treated for 4 weeks. In the fifth week rats were decapitated. Macroscopic damage scores of colonic mucosa were calculated. A 4mL blood sample was taken to detect the contents of serum tumor necrosis factor -α (TNF-α) and interleukin 8 (IL-8) by the double antibody sandwich ABC-ELISA method (enzyme-linked immunosorbent assay). Colonic tissues with the most obvious lesions were obtained using a surgical scissor. A routine hematoxylin-eosin (HE) staining method was used to stain pathological specimens and images of staining results were obtained. Histological injury scores of colonic mucosa were calculated. Ulcerative colitis model rats had the highest macroscopic damage scores and histological injury scores of colonic mucosa. After treatment the contents of TNF-α and IL-8 decreased significantly in the group of curcumin plus soy oligosaccharide compared with the model group with statistical significance (P <0.01) while the contents were close to those in the SASP group. There was no statistical significance (P> 0.05). The treatment could decrease TNF-α and IL- 8 expression and reduce colonic mucosa inflammation and tissue damage.

Abstract
Rotavirus-related diarrhoea is considered one of the most important diseases in field animal production. In addition to the classic vaccine strategy, a number of studies have utilised probiotics, such as Lactobacillus rhamnosus GG (LGG), to prevent rotavirus-induced diarrhoea. Although it has been partially revealed that Toll-like receptors (TLRs) are involved in the LGG-mediated protection against rotavirus infection, the details of the underlying immunologic mechanisms remain largely unknown. In this study, three-to-four-week-old female BALB/c mice were divided into three groups and orally administered phosphate buffered saline (PBS), PBS plus rotavirus or LGG plus rotavirus, respectively. The differentiation and maturation of dendritic cells (DCs) were then determined by FACS, the expression levels of TLR-3 and nuclear factor kappa beta (NF-κB) were evaluated using real time PCR, and the production of inflammatory cytokines in mesenteric lymph nodes (MLNs) were determined by ELISA. The results demonstrated that rotavirus infection significantly increased the percentage of CD11c+CD11b+CD8a- DCs and decreased the percentage of CD11c+CD11b-CD8a+ DCs in MLNs. By contrast, the presence of LGG significantly decreased the percentage of CD11c+CD11b+CD8a- DCs and increased the percentage of CD11c+CD11b-CD8a+ DCs, which indicates that the differentiation of DCs is involved in the protective effects of LGG. Rotavirus infection also resulted in the increased expression of surface markers such as CD40, CD80 and MHC-II in DCs, and the administration of LGG significantly increased the expression level further. The mRNA levels of TLR-3 and NF-κB in the intestine and MLNs were also significantly increased in the presence of rotavirus, which was further increased in the presence of LGG. The production of inflammatory cytokines was also determined, and the results showed that rotavirus caused the increased production of interleukin (IL)-12 and tumour necrosis factor alpha; this effect was further enhanced by LGG. Meanwhile, although rotavirus infection led to the increased production of IL-6 and IL-10, the presence of LGG significantly decreased the mRNA levels of these cytokines. By contrast, rotavirus infection resulted in the decreased production of interferon gamma (IFN-γ), and the administration of LGG significantly increased the levels of IFN-γ. Taken together, the protective effects of LGG were partially due to the modulation of the differentiation and maturation of DCs, the increased production of TLR-3 and NF-κB, and the modulation of inflammatory cytokines.

Abstract
BACKGROUND A previous study provided evidence for a genetic association between PPP2CA on 5q31.1 and systemic lupus erythematosus (SLE) across multi-ancestral cohorts, but failed to find significant evidence for an association in the Han Chinese population. OBJECTIVES To explore the association between this locus and SLE using data from our previously published genome-wide association study (GWAS). METHODS Single-nucleotide polymorphisms (SNPs) rs7726414 and rs244689 (near TCF7 and PPP2CA in 5q31.1) were selected as candidate independent associations from a large-scale study in a Han Chinese population consisting of 1047 cases and 1205 controls. Subsequently, 3509 cases and 8246 controls were genotyped in two further replication studies. We then investigated the SNPs' associations with SLE subphenotypes and gene expression in peripheral blood mononuclear cells. RESULTS Highly significant associations with SLE in the Han Chinese population were detected for SNPs rs7726414 and rs244689 by combining the genotype data from our previous GWAS and two independent replication cohorts. Further conditional analyses indicated that these two SNPs contribute to disease susceptibility independently. A significant association with SLE, age at diagnosis < 20 years, was found for rs7726414 (P = 0·001). The expression levels of TCF7 and PPP2CA messenger RNA in patients with SLE were significantly decreased compared with those in healthy controls. CONCLUSIONS This study found evidence for multiple associations with SLE in 5q31.1 at genome-wide levels of significance for the first time in a Han Chinese population, in a combined genotype dataset. These findings suggest that variants in the 5q31.1 locus not only provide novel insights into the genetic architecture of SLE, but also contribute to the complex subphenotypes of SLE.

Abstract
FaeG is the major subunit of K88 fimbriae. These cell surface attachments are considered to be the major virulence factor of enterotoxigenic Escherichia coli (ETEC), which causes diarrhoea in piglets. The use of dendritic cell-targeting peptide (DCpep) has been demonstrated to be an effective approach to enhance the immunity of vaccines. Lactobacillus plantarum is an attractive candidate for oral vaccination owing to its beneficial effects and safety. In this study, L. plantarum was employed to deliver a FaeG-DCpep fusion antigen, and the immune response in mice was evaluated. The synthesis of FaeG-DCpep dramatically increased the adhesion of recombinant L. plantarum (RLP) to IPEC-J2 cell surfaces, resulting in direct competition between L. plantarum and ETEC during adhesion assays. Significantly higher levels of body weight gain, sera immunoglobulin G and intestinal immunoglobulin A were observed in BALB/c mice immunised with RLP. In addition, the number of CD19+ B cells and CD11c+DC cells and the expression levels of several cytokines in the spleen and lymph nodes increased significantly compared to non-immunised mice. The oral administration of RLP also alleviated the symptoms of ETEC challenge, as shown by haematoxylin-eosin staining, indicating that RLP may be an efficient vaccine candidate.

Abstract
OBJECTIVES During an outbreak of invasive meningococcal B disease on a university campus, we explored the knowledge, attitudes, beliefs, and behaviors of members of the university community in relation to the disease, the vaccine, and the vaccination program. DESIGN All students, faculty and staff were invited by email to participate in a 71-item online survey, which was administered after completion of the mass clinics for the first and second doses of a meningococcal B vaccination program. RESULTS A total of 404 individuals responded to the survey; 75.7% were students. Knowledge about meningococcal disease and vaccine was generally high; more than 70% correct responses were received on each knowledge question except for one question about the different meningococcal serogroups. Gender (female) and higher knowledge scores were significantly associated with either being immunized or intending to be immunized (p<0.05). Positive attitudes about immunization, concern about meningococccal infection, a sense of community responsibility, and trust in public health advice also correlated with being vaccinated or intending to be vaccinated (p<0.05). CONCLUSIONS A successful mass vaccination program in a Nova Scotia university was associated with high levels of knowledge, positive attitudes toward vaccination, and positive attitudes toward public health recommendations.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by extensive immune response, including over-activation of T and B cell development of pathogenic autoantibodies, organ damage induced by the formation and deposition of immune complex and the abnormal elevation of type I interferon. Semaphorin5A (Sema5A) is involved essentially in immune cell regulation and is also implicated in the pathogenesis of autoimmune disorders. We aimed to evaluate the role of Sema5A in patients with SLE. Serum levels of Sema5A were tested by enzyme-linked immunosorbent assay (ELISA) in 152 SLE patients and 48 healthy controls. The message ribonucleic acid (mRNA) expression levels of Sema5A and ADAM metallopeptidase domain 17 (ADAM17) in the peripheral blood mononuclear cells (PBMC) from 43 patients with SLE and 19 healthy controls were detected by the real-time-quantitative polymerase chain reaction (qPCR). Serum Sema5A levels were increased significantly in SLE patients compared with healthy controls (P < 0·001). Elevated levels of Sema5A were correlated positively with 24-h proteinuria excretion (r = 0·558, P < 0·0001), SLE disease activity index (SLEDAI) (r = 0·278, P = 0·0006) and C-reactive protein (CRP) (r = 0·266, P = 0·002), but negatively with planet (PLT) (r = -0·294, P = 0·0003) and complement 3 (C3) (r = -0·287, P = 0·0004) in SLE patients. Patients with elevated Sema5A levels showed higher incidence of rash, serositis and nephritis (P < 0·05 or P < 0·001). Patients with decreased PLT, C3 or positive for proteinuria also showed elevated Sema5A (P < 0·001 or P < 0·05). The mRNA ADAM17 was increased in SLE patients and correlated positively with serum Sema5A levels. Our data demonstrated that elevated serum Sema5A in SLE patients correlated with disease activity and are involved in kidney and blood system damage; ADAM17 might be involved in the release of secreted Sema5A.

Abstract
目的 比较不同重组人TPO(rhTPO)方案联合免疫抑制剂治疗重型再生障碍性贫血(SAA)的近期疗效。 方法 回顾性分析接受一线免疫抑制治疗(IST)的61例成人SAA初诊患者资料,对比分析18例IST联合rhTPO每日1次(连续组)与43例IST联合rhTPO隔日1次(间日组)患者的疗效差异。 结果 两组患者在IST前基础临床特征差异无统计学意义。IST后3个月和6个月进行疗效评估,连续组与间日组患者总体血液学反应率比较差异无统计学意义(3个月:50.0%对51.2%,P= 0.934;6个月:77.8%对69.8%,P=0.525)。连续组IST后3个月良好血液学反应率明显高于间日组(38.9%对9.3%,P=0.011)。rhTPO应用后4周和8周两组脱离红细胞输注率差异无统计学意义(4周:22.2%对18.6%,P=0.736; 8周:55.6%对46.5%,P=0.519),而治疗后8周脱离血小板输注率连续组明显高于间日组(88.9%对48.8%,P=0.003)。每日连续应用rhTPO治疗并不增加不良反应事件的发生。 结论 每日1次较隔日1次应用rhTPO促进SAA造血恢复和减少血小板输注依赖更为有效。

Abstract
目的 分析肝炎相关再生障性贫血(HAAA)临床特征,评价其免疫抑制治疗(IST)疗效及生存状况。 方法 回顾性分析944例接受IST的重型/极重型AA(SAA/VSAA)患者,比较41例HAAA患者与年龄、造血衰竭程度相匹配的123例特发性AA(IAA)临床特征、血液学反应率、长期生存率及克隆性演变情况。 结果 944例SAA/VSAA患者中HAAA 41例(4.34%),HAAA患者中VSAA所占比例明显高于IAA患者(65.9%对39.4%,P=0.001)。HAAA与匹配的IAA比较,患者感染发生率差异无统计学意义,但感染控制所需时间明显延长[21 (4~100) d对13 (3~139) d,P=0.048]。HAAA患者CD3+、CD3+CD4+、CD3+CD8+ T淋巴细胞绝对值及CD4+/CD8+细胞比值均明显低于IAA患者,而CD3+ CD8+ T淋巴细胞比例明显高于IAA患者,差异均有统计学意义。HAAA与IAA患者IST后3个月(34.1%对34.1%,P=1.000)、6个月(56.1%对53.7%,P=0.787)及12个月(73.2%对68.3%,P=0.558)血液学反应率差异无统计学意义,两组患者预期5年总生存(OS)率、无事件生存(EFS)率比较差异均无统计学意义(OS率:90.0%对87.1%,P=0.700;EFS率:71.9%对62.4%,P=0.450)。 结论 HAAA少见,造血衰竭更为严重,感染相对难以控制,采用标准IST方案治疗可获得与IAA患者相当的疗效。
