Abstract
Objective: To investigate the association between types of obesity and the 10-year-coronary heart disease risk in Tibet and Xinjiang of China. Methods: Using the multi-stage random sampling method, 7 631 participants aged 35 or older were examined under the International Standardized Examination process but with only 5 802 were eligible for analysis, in the 2015-2016 season. Results: The prevalence rates of general obesity, central obesity, visceral obesity and compound obesity were 0.53%, 12.62%, 10.08% and 42.35%, respectively. Out of all the compound obesity cases, 58.65% (1 441/2 457) of them appeared as having all types of obesity in our study. Risk related to the 10-year-coronary heart disease was higher in men than in women [(3.05±4.14)% vs. (1.42±2.37) %, P<0.000 1. Compound obesity (30.16%) showed the highest proportion on the risk of 10-year-coronary heart disease than central obesity (28.01%), visceral obesity (18.46%) or the general obesity (19.35%). After adjustment for confounding factors, results from the multivariate analysis showed the risk in compound obesity was higher than central obesity, visceral obesity or general obesity and was associated with the highest risk on the 10-year-coronary heart disease (OR=2.889, 95%CI: 2.525-3.305). People with anomalous BMI and WC seemed to have had the higher risk (OR=3.168, 95%CI: 2.730-3.677). Conclusions: Obesity was popular in the residents of Tibet and Xinjiang areas of China. Men and people with compound obesity (especially both BMI and WC were abnormal) seemed to carry greater risk on the 10-year-coronary heart disease.

Abstract
Objective: To understand the prevalence of senile dementia in the elderly aged ≥60 years in China between 2000 and 2015. Methods: Publications between 2000 and 2015 were retrieved from China National Knowledge Infrastructure (CNKI), Wanfang Databases, Chinese Science and Technology Journal Databases (VIP) and PubMed. Observational studies on prevalence of senile dementia were included. Meta-analysis was carried out by using R software. Results: A total of 25 papers were included in this study. The total number of participants investigated was 76 980, with 4 295 dementia cases identified. The prevalence of senile dementia in the elderly was 5.15% (95%CI: 4.21%-6.09%); Subgroup analysis showed that the women had a higher prevalence (6.08%) than the men (4.10%); and the prevalence was significant increased with age (The senile dementia prevalence was 1.01% in age groups 60-64 years, but 23.60% in age group ≥85 years). The prevalence of Alzheimer's disease (3.56%) was higher than that of cerebral vascular dementia (1.11%). The senile dementia prevalence in the illiterate was 8.74%, higher than 3.17% in the literate. The prevalence of senile dementia in the unmarried was 6.83%, higher than that in the married (3.95%). Conclusion: The prevalence of senile dementia was high in the population aged ≥60 years in China. Age, sex, education level and marital status might influence the prevalence of senile dementia.

Abstract
Objective: The therapeutic effect of acid fibroblast growth factor 1(FGF1) on rats with diabetic cardiomyopathy (DCM) was evaluated by using nano-liposomes combined with ultrasound-targeted microbubble destruction technique (UTMD). Methods: The FGF1-loaded nano-liposomes were prepared by water-in-water emulsion method combined with lyophilization technique.TypeⅠdiabetes model was induced by intraperitoneal injection of streptozotocin (STZ, 70 mg/kg) in 60 male SD rats.Sixteen weeks later, diabetic rats were randomly divided into: placebo group (saline treatment), FGF1 group, FGF1-loaded nano-liposomes group, and FGF1-loaded nano-liposomes plus UTMD group (n=15 each). After two weeks of intervention followed by 2 weeks intervention stop, all rats underwent cardiac catheterization, and the left ventricular end-systolic pressure (LVESP), left ventricular end-diastolic pressure (LVEDP) and the maximal increase/decrease rate of left ventricular pressure (LV±dp/dtmax) were measured.Then, the rats were sacrificed and myocardial tissue were obtained for Masson trichrome staining, TUNEL apoptotic staining and CD31 immunohistochemistry staining to quantify myocardial collagen fraction (CVF), cardiac myocyte apoptotic index and myocardial microvascular density (MVD). Results: (1)Scanning electron microscope results revealed good morphology and FGF1 encapsulation efficiency (84.3±2.8)% with high stability and dispensability of FGF1 loaded nano-liposomes.(2)The hemodynamic evaluation showed that LVESP, LV + dp/dt(max) and LV -dp/dt(max) were all significantly higher, while LVEDP was significantly lower in the FGF1-loaded nano-liposome+ UTMD group than in DCM group, FGF1 solution group, and FGF1 nano-liposome group(all P<0.05). (3)The Masson trichrome staining demonstrated that CVF was significantly higher in all DCM groups than in control group and was significantly lower in the FGF1-loaded nano-liposome+ UTMD group than in DCM group, FGF1 solution group, and FGF1 nano-liposome group (all P<0.05). (4)The CD31 immunohistochemical staining results showed that MVD was significantly lower in all DCM groups than in control group and was significantly higher in the FGF1-loaded nano-liposome+ UTMD group than in DCM group, FGF1 solution group, and FGF1 nano-liposome group (all P<0.05). (5)The TUNEL results showed that apoptotic index was significantly higher in all DCM groups than in control group and was significantly lower in the FGF1-loaded nano-liposome + UTMD group than in DCM group, FGF1 solution group, and FGF1 nano-liposome group (all P<0.05). Conclusion: FGF1 nano-liposomes combining with UTMD technique can significantly improve cardiac functions and attenuate myocardial CVF and apoptosis and enhance myocardial MVD in DCM rats.

Abstract
Objective: To investigate the association between body fat percentage (BFP), visceral fat index (VFI) and Cardiometabolic Risk Factor Clustering (CRFC), among population aged 35 or older in Tibet and Xinjiang areas. Methods: Using the stratified multi-stage random sampling method, 7 571 residents aged 35 or above were examined with international standardized examination between 2015 and 2016. Of the eligible 5 643 participants, association of BFP and VFI with CRFC was defined as having two or more of the four risk factors: hypertension, diabetes mellitus, high TG and low HDL-C, at the same time. Logistic regression analysis and receiver operating characteristic (ROC) curve analysis were employed to further explore the relationships. Results: The overall prevalence of CRFC among aged 35 and older population in Tibet and Xinjiang areas was 9.78%. BFP and VFI were divided into four groups by quartile. After adjustment for age, gender, race, cigarette smoking, alcohol consumption, education attainments, and altitude of residence, ORs of CRFC seemed to have increased with BFP and VFI. Compared with people having BFP of 5.0%-27.0%, the OR(95% CI) were 1.15(0.86-1.54), 1.48(1.05-2.07) and 1.72(1.10-2.68) for the ones who presented 27.1%-31.7%, 31.8%-36.6% and 36.7%-50.0% of BFP. Compared to people of having 1-6 of VFI, with OR (95%CI) as 1.20(0.81-1.79), 1.91(1.30-2.80) and 3.91(2.64-5.77) for the ones having 7-9, 10-13 and 14-30 of VFI. Areas under the curve (AUC) of CRFC appeared as 0.55 for BFP and 0.70 for VFI, respectively, with statistically significant difference (P<0.01). Conclusion: Both BFP and VFI levels were closely associated with CRFC while VFI seemed to have a better predictive value than the BFP.

Abstract
Objective: To investigate the prevalence of metabolic syndrome (MS) among adults in rural areas of Ningxia Hui autonomous region. Methods: A cross-sectional study was conducted in 10 639 adults enrolled with a multistage method from Jingyuan County. The MS was identified according to Chinese type 2 diabetes prevention guide (2013). Results: Among all the subjects, 17.4% of them met the MS definition with the standardized prevalence of 14.7% after adjustment of sex and age. The prevalence and standardized rate of MS in men were 19.9% and 17.3%, and in women were 15.3% and 13.5%.The prevalence of MS in men was higher than that in women(P<0.001) and increased with aging in both genders. The prevalence and standardized rate of abdominal obesity, hyperglycemia, hypertension, high triglycerides, and low HDL-C were 19.5% and 16.7%, 15.0% and 12.9%, 42.0% and 37.1%, 25.8% and 23.1%, 28.5% and 27.7%, respectively. The rate of abdominal obesity was higher in women than in men (20.5% vs 18.2%, P=0.004), whereas the rate of hypertension, high triglycerides, and low HDL-C were higher in men than in women (all P<0.01). The prevalence of having one parameter of the MS was 68.4%. Conclusion: The prevalence of MS is higher in rural areas of Ningxia Hui autonomous region, suggesting that a series of comprehensive prevention measures should be carried out to prevent and control the MS so as to improve the public health conditions in rural areas.

Abstract
Deletion of major histocompatibility complex class I chain-related genes A (MICA*Del) was investigated in 3,411 DNA samples from two southern Chinese Han populations (Hunan Han, HNH; Guangdong Han, GDH), two northern Chinese populations (Inner Mongolia Han, IMH; Inner Mongolia Mongol, IMM) and one southeastern Chinese Han population (Fujian Han, FJH) using an in-house polymerase chain reaction-sequence specific priming (PCR-SSP) assay, which enables direct discrimination between heterozygote and homozygote for MICA*Del. MICA*Del showed a frequency ranging from 0.8% in FJH to 5.7% in IMM (Pcorrected < 0.05), indicating northward increase in frequency of MICA*Del in Chinese populations. In contrast to the association reported recently in a Taiwan Chinese population and a Malaysian Chinese cohort, MICA*Del distribution did not differ between 1,120 patients with nasopharyngeal carcinoma (NPC) and 1,483 normal controls in the HNH population (1.03% in NPC cases vs 1.18% in the controls, OR (95% CI) = 0.87 (0.51-1.47), p = 0.69). Further gender-stratified analysis also failed to disclose any male-specific association reported in a Taiwan Chinese population. Multi-locus typing of the 94 samples carrying MICA*Del revealed two new haplotypes, HLA-A*11:01-B*13:01-MICA*Del-MICB*009N-DRB1*04:06 and HLA-B*35:01-MICA*Del-MICB*009N-DRB1*15:01, in addition to HLA-B*48-MICA*Del. Unexpectedly, two samples with MICA*Del in the HNH population were each consistently found to have two distinct MICA alleles, indicating the existence of two MICA gene copies on certain HLA haplotypes. Based on the results from a sizeable case-control study, our data suggest that there is no association between MICA*Del and NPC in the southern Chinese Han population.

Abstract
OBJECTIVE To summarize surgical experience during the conduction of robotic mitral valve repair and evaluate the long-term follow-up results. METHODS From January 2007 to September 2014, 110 consecutive patients underwent robotic mitral valve repair under da Vinci Surgical System (Intuitive Surgical, USA) in Chinese PLA General Hospital were enrolled. The age of the patients was 14 to 65(45±12) years old. The male to female ratio was 2.3∶1. Among them, 95.5%(105/110) of the cases was diagnosed as mitral regurgitation and 4.5%(5/110) of them was diagnosed as mitral stenosis, and most of them (63.3%) needed triangular or quadrangular resection. Nitinol U-clips (58.1%), running suture (31.2%) and Cor-Knot™ suture device (10.8%) were used to secure the annuloplasty ring. The operative data were collected and patients were regularly followed up echocardiographically as long as 7 years. RESULTS All the surgeries were finished by the same surgeon. One case required conversion to sternotomy. The mean cardiopulmonary bypass (CPB) and cross-clamp time was 70 to 152 (121.0±34.3) and 47 to 122 (82.6±25.3) minutes respectively. After surgery, one death (0.91%) and two cases of stroke (1.82%) occurred. Three cases of early prosthetic failure (2.73%) were noticed. All patients were successfully followed up for a median of 50 (range, 1 month to 7 years) months and 94.5%(104/110) of them had no re-operation. CONCLUSION Robotic mitral valve repair is a safe and effective surgical method with excellent long-term outcomes.

Abstract
Objective: The aim of the current study was to investigate the predictive value of fragmented QRS wave ( fQRS) for the prognosis of patients with coronary heart disease (CHD). Methods: A total of 714 consecutive patients with confirmed CHD were included from Department of Cardiology, General Hospital of PLA between January 2013 and January 2014, and were divided into fQRS group and non-fQRS group based on the presence of fQRS wave or not according to Electrocardiograph (ECG). The baseline, ECG characteristic value, the echocardiography results of the patients were compared between the two groups. Cardiac events were recorded in all patients during 12 months' follow-up. Subgroup analysis was also conducted among patients with abnormal Q wave to investigate the association between fQRS and cardiovascular events. Results: A total of 673 patients completed the follow-up, with 533 in fQRS group and 140 in non-fQRS group. The P wave duration in the fQRS group was longer than non-fQRS group [(92±21) vs (82±23)ms, P<0.01]. The left ventricular ejection fraction (LVEF) value in the fQRS group was lower than non-fQRS group (42%±22% vs 49%±15%, P<0.01) according to echocardiography results. The subgroup analysis with abnormal Q wave showed that compared with non-fQRS group, the left ventricular ejection fraction (LVEF) value in the group of fQRS was lower (38%±21% vs 50%±7%, P<0.01). There was statistically significant in the mortality of patients within follow-up period between the two groups (P<0.05), and the survival time in fQRS group was shorter than the non-fQRS group [(28.3±3.4) vs (30.5±1.5)months, P<0.01]. Conclusion: FQRS presence in body surface ECG of CHD patients with abnormal Q wave is a sign for increased risk of cardiovascular events, which can serve as an indicator to identify CHD patients at high risk of death.

Abstract
Photochemical smog, characterized by high concentrations of ozone (O3) and fine particles (PM2.5) in the atmosphere, has become one of the top environmental concerns in China. Volatile organic compounds (VOCs), one of the key precursors of O3 and secondary organic aerosol (SOA) (an important component of PM2.5), have a critical influence on atmospheric chemistry and subsequently affect regional and global climate. Thus, VOCs have been extensively studied in many cities and regions in China, especially in the North China Plain, the Yangtze River Delta and the Pearl River Delta regions where photochemical smog pollution has become increasingly worse over recent decades. This paper reviews the main studies conducted in China on the characteristics and sources of VOCs, their relationship with O3 and SOA, and their removal technology. This paper also provides an integrated literature review on the formulation and implementation of effective control strategies of VOCs and photochemical smog, as well as suggestions for future directions of VOCs study in China.

Abstract
AIMS To evaluate the sampling adequacy and diagnostic accuracy of the endometrial SAP-l sampling device in detecting endometrial lesions based on histopathological examination. MATERIALS AND METHODS In total, 182 patients who required an endometrial biopsy were enrolled in this study. All of the patients underwent endometrial biopsies with the SAP-l sampler prior to hysteroscopy (169/182) or dilatation and curettage (D&C) (13/182). Endometrial tissues were obtained at biopsy for histopathological examination. RESULTS Ad- equate endometrial specimens were obtained in 148 of 182 patients (81.32%). Menopause (p = 0.000), endometrial thickness (p = 0.004), and the types of endometrial diseases (p = 0.009) differed significantly between the two groups. Among the 169 patients who underwent hysteroscopy, sampling scratches were observed in the uterine cavity in 147 cases (86.98%). Compared to traditional methods, such as hysteroscopy and D&C, the sampling diagnostic sensitivity, specificity, and positive and negative predictive values were 82.35%, 100%, 100% , and 97.76% for endometrial carcinoma (n=17) and 37.5%, 100%, 100% and 97.76% for endometrial atypical hyperplasia (n=8), respectively. Those that were misdiagnosed occurred because the lesions were focal or localized in a small part of the uterine cavity. The sampling diagnostic sensitivity for polyps (n=32) was 12.5%. Two patients with submucosal leiomyoma went undiagnosed based on the sample specimens. CONCLUSION Endometrial sampling using the SAP-l sampler is a minimally invasive altemative technique for obtaining adequate endometrial specimens for histopathological examination. The SAP-l sampler was useful in detecting endometrial carcinoma and atypical hyperplasia cases that were not highly suspected to be localized; however, this method was not useful in detecting endometrial polyps and submucosal leiomyomas.

Abstract
Objective: To investigate clinical treatment and outcome of mesh-related pain after pelvic floor reconstruction. Methods: Twelve patients were referred to Peking University People's Hospital for post-operation pain related to polypropylene mesh or tape used in pelvic floor reconstruction and received reoperation from January 2007 to December 2014. The demographic characteristics, clinical manifestation, operation method and follow-up outcome were retrospectively analyzed, and current literature was also reviewed. Results: (1) General information: the median age was 54 years old (range 43-74 years old). The median vaginal delivery times was 2 (range 1-5). Initial pelvic floor operation procedures included 4 cases vaginal mesh, 5 cases vaginal mesh plus tension-free vaginal tape (TVT), 1 case rectal surface mesh implantation, and 2 cases sacrocolpopexy. (2) Related complications: all 12 patients had pain-related post-operation symptoms including dyspareunia, perineal pain, urination and defecation difficulty. Seven patients also complicated with other symptoms including discharge and bleeding. Mean time from first operation to medical consultation was 30 months (range 1-72 months). (3) Reoperation results: all 12 patients received reoperation on mesh revision or tape, 10 cases of them reoperated by vaginal approach, while the other 2 cases by laparoscopy. The range of the mesh or tape depended on tender or firm tissue and scar by palpation. The visual analogue scale (VAS) was significantly improved, which was 7.1 ± 2.2 pre-operation, and 0.9 ± 1.9 post-operation (95% CI: 4.48-7.86, P<0.01). Conclusions: Pain is one of the reason why patients was removal of the mesh or tape after pelvic floor reconstruction operation. The surgery procedure may be considered as partial or entire mesh or tape excision by vaginal or abdominal way. Mesh or tape removal surgery could relieve related pain and other complications, and the VAS score was significantly improved after surgical management.

Abstract
InN-based metal-insulator-semiconductor (MIS) structures were prepared with Al2O3 as the gate oxides. Surface morphologies of InN films are improved with increasing Mg doping concentrations. At high frequencies, the measured capacitance densities deviate from the real ones with turning frequencies inversely proportional to series resistances. An ultralow leakage current density of 1.35 × 10(-9) A/cm(2) at 1 V is obtained. Fowler-Nordheim tunneling is the main mechanism of the leakage current at high fields, while Schottky emission dominates at low fields. Capacitance densities shift with different biases, indicating that the InN-based MIS structures can serve as potential candidates for MIS field-effect transistors.

Abstract
Objective: To investigate the differences and similarities between drug-induced liver injury (DILI) and autoimmune hepatitis (AIH) in serum biochemical parameters and liver pathology, and to provide some thoughts for clinical diagnosis and differentiation of these two diseases. Methods: A retrospective analysis was performed for the biochemical, immunological, autoantibody, and liver pathological data of 106 DILI patients and 63 AIH patients who were hospitalized, diagnosed, and treated in our hospital from January 2012 to October 2014. The patients' general data, biochemical parameters, immunological data, Ishak score, and qualitative changes in liver tissue were analyzed and compared. The Kruskal-Wallis test was used for comparison of nonparametric data between multiple groups, the Nemenyi test was used for comparison of nonparametric data between any two groups, the Wilcoxon rank sum test was used for comparison of Ishak scores, and the chi-square test was used for comparison of constituent ratio of categorical data. Results: There were significant differences between AIH group and DILI hepatocyte injury group/mixed-type DILI group in the following serum biochemical parameters: alanine aminotransferase (187.2 U/Lvs 1 326.5 U/L and 455.6,P< 0.05), aspartate aminotransferase (172.2 U/L vs 759.5 U/L and 349.5 U/L,P<0.05), alkaline phosphatase (209.3 U/L vs 157.3 U/L and 169.4 U/L,P< 0.05), gamma-glutamyl transferase (254.8 U/L vs 176.5 U/L and 170.5 U/L,P< 0.05), total bilirubin (37.2μmol/L vs 95.8μmol/L and 52.6μmol/L,P< 0.05), serum iron (18.9μmol/L vs 36.2μmol/L and 23.9μmol/L,P< 0.05), serum ferritin (122.5μmol/L vs 410.4μmol/L and 186.5μmol/L,P< 0.05), immunoglobulin G (18.4 g/L vs 12.6 g/L and 12.3 g/L,P< 0.05), and immunoglobulin M (1.8 g/L vs 1.3 g/L and 1.1 g/L,P< 0.05). There were also significant differences between AIH group and DILI hepatocyte injury group/mixed-type DILI group in the Ishak score for interface inflammation (2.2±0.8 vs 1.3±0.7 and 1.3±0.6,P< 0.05), Ishak score for portal inflammation (2.3±0.9 vs 1.5±0.7 and 1.4±0.8,P< 0.05), and fibrosis score (2.8±1.1 vs 1.5±0.7 and 1.3±0.7,P< 0.05). There were significant differences between AIH group and DILI hepatocyte injury group/mixed-type DILI group in the proportion of wax-like deposition (0 vs 29.2% and 34.5%, P <0.05) and proportion of iron deposition (11.1% vs 52.1% and 25.9%,P< 0.05). Conclusion: There are differences in biochemistry, immunology, and liver histology between DILI and AIH patients. AIH patients have more serious interface inflammation and portal inflammation and a higher fibrosis degree compared with DILI patients, while DILI patients have greater proportions of wax-like deposition and iron deposition compared with AIH patients.

Abstract
Chronic subjective dizziness(CSD) was defined as persistent nonvertiginous dizziness or subjective unsteadiness. Patients are hypersensitivity to motion stimuli, such as head movement and motion of objects in the visual surrounding, and have difficulty with precise visual tasks. The concept of CSD was first proposed by Staab and Ruckenstein, which indicates relationships between chronic dizziness and acute vestibular or psychiatric disorders, including neuro-otologic type, psychiatric type or interactive type. Treatment includes vestibular rehabilitation therapy, pharmacologic interventions and psycho-behavioral interventions(cognitive behavioral therapy).

Abstract
OBJECTIVE To evaluate the seven existing vaginal birth after cesarean (VBAC) screening tools and to identify additional factors that may predict VBAC or failed trial of labor in China. METHODS In the study, 53 patients with 1 previous cesarean delivery who then delivered between January 1, 2007 and Novenber 31, 2014 were recruited. The average age of the patients was (32.1±3.5) years,the average gestational age was (38.0±2.3) weeks. There was no significant difference of the successful group and the failed group in the maternal/neonatal mortality and morbidity, also in the incidence of the postpartum hemorrhage and the postpartum infection. The probability of VBAC was calculated for each participant using 7 prediction models created by Weinstein, Flamm, Grobman, Gonen, Troyer, Smith and Torri. The data were analyzed using t test, rank-sum test, and receiver operating curve analysis. RESULTS 44 trial of labor patients had a vaginal birth after cesarean delivery, and the successful rate was 83%. The scores between the successful group and the failed group had significant difference when evaluated by Weinstein and Grobman scoring models only. After recalculating the successful rate of VBAC in different score levels according to the references, there was significant difference between the rates of different score levels when evaluated by the Weinstein model. The successful rates of different score levels were higher compared to the references (<50%) when evaluated by the Troyer (70%), Gonen (60%), Torri (85.7%) models. The area under the receiver operating characteristic curve of Weinstein prediction model (0.746) and Flamm prediction model (0.723) were more than 0.7, and there was no significant difference between the seven models. CONCLUSION Among the seven scoring models, the Weinstein model is more applicable to the population of our country, but a new model more applying to Chinese women still needs to be created.

Abstract
BACKGROUND The 308-nm excimer laser had been proved to be a time-efficient and potent therapeutic alternative for the management of vitiligo. Different results had been reported in different ethnic populations. OBJECTIVE To investigate the efficacy and related contributing factors of 308-nm excimer laser in Chinese vitiligo patients. METHODS A total of 979 Chinese patients (3478 lesions) with progressive-stage vitiligo who had received 308-nm excimer laser treatment were recruited from the vitiligo clinic of Shandong Provincial Hospital of Dermatology &Venereology from 2012 to 2014. Efficacy of treatment was evaluated at the end of session by two independent dermatologists based on the before and after images taken. Repigmentation was graded on a 4-point scale: grade 1, poor repigmentation (0-25%); grade 2, moderate repigmentation (26-50%); grade 3, good repigmentation (51-75%); grade 4, excellent repigmentation (76-100%). RESULTS The mean grade of repigmentation was 2.29, 44.22% showed less than 25% repigmentation, 16.27% showed 26-50% repigmentation, 5.95% showed 51-75% repigmentation and 33.55% showed more than 76% repigmentation. The repigmentation of facial lesions was better than lesions located elsewhere (P < 0.0001), the best response was noted in the periorbital region, while lesions on hands and feet showed poor repigmentation (P < 0.0001). The degree of repigmentation was negatively correlated with disease duration (r = -0.268, P < 0.001), age (r = -0.095, P < 0.001) and shape of lesions (r = -0.114, P < 0.001), whereas it was positively correlated with treatment frequency (r = 0.270, P < 0.001). Lesions with concurrent poliosis were more likely resistant to treatments. CONCLUSION 308-nm excimer laser appears to be an effective and safe treatment in Chinese vitiligo patients. The clinical response and treatment efficacy was affected by many factors such as age, affected anatomical area, shape of the lesion, disease duration and treatment frequencies.

Abstract
The dwarf and narrow-leaf rice (Oryza sativa L.) mutant dnl3 was isolated from the Japonica cultivar Zhonghua 11 (wild-type). dnl3 exhibited pleiotropic developmental defects. The narrow-leaf phenotype resulted from a marked reduction in the number of vascular bundles, while the dwarf stature was caused by the formation of foreshortened internodes and a reduced number of parenchyma cells. The suggestion that cell division is impaired in the mutant was consistent with the transcriptional behavior of various genes associated with cell division. The mutant was less responsive to exogenously supplied gibberellic acid than the wild-type, and profiling the transcription of genes involved in gibberellin synthesis and response revealed that a lesion in the mutant affected gibberellin signal transduction. The dnl3 phenotype was inherited as a single-dominant gene, mapping within a 19.1-kb region of chromosome 12, which was found to harbor three open reading frames. Resequencing the open reading frames revealed that the mutant carried an allele at one of the three genes that differed from the wild-type sequence by 2-bp deletions; this gene encoded a cellulose synthase-like D4 (CSLD4) protein. Therefore, OsCSLD4 is a candidate gene for DNL3. DNL3 was expressed in all of the rice organs tested at the heading stage, particularly in the leaves, roots, and culms. These results suggest that DNL3 plays important roles in rice leaf morphogenesis and vegetative development.

Abstract
The interleukin-1α (IL-1α) gene appears to play a role in the pathogenesis of type 1 diabetes (T1D). Therefore, the aim of this study was to investigate the contribution of the IL-1 rs1800587 gene polymorphism to susceptibility to T1D in Chinese children. This case-control study included 332 Chinese children with T1D and 332 healthy controls. Identification of genetic variants of rs1800587 in the IL-1α gene was performed by polymerase chain reaction amplification. The IL-1α rs1800587 polymorphism demonstrated a significant association with T1D risk. The allelic frequency significantly differed between the T1D and control groups [odds ratio (OR) = 0.7; 95% confidence interval (CI) = 0.52-0.86; P = 0.002]. Furthermore, significant differences were observed in the dominant model (CC/CT + TT; OR = 0.6; 95%CI = 0.46-0.85; P = 0.003). In T1D patients, the prevalence of hypertension in T allele carriers was 4.2-fold higher than that in C allele carriers, (95%CI = 2.67-6.58; P < 0.001). In conclusion, the present study found evidence of a significant association between the rs1800587 polymorphism in the IL-1α gene and T1D.

Abstract
This study was designed to explore the regulatory effects of male germ cell secreting factor NODAL on Sertoli cell fate decisions from obstructive azoospermia (OA) and nonobstructive azoospermia (NOA) patients. Human Sertoli cells and male germ cells were isolated using two-step enzymatic digestion and SATPUT from testes of azoospermia patients. Expression of NODAL and its multiple receptors in human Sertoli cells and male germ cells were characterized by reverse transcription-polymerase chain reaction (RT-PCR) and immunochemistry. Human recombinant NODAL and its receptor inhibitor SB431542 were employed to probe their effect on the proliferation of Sertoli cells using the CCK-8 assay. Quantitative PCR and Western blots were utilized to assess the expression of Sertoli cell functional genes and proteins. NODAL was found to be expressed in male germ cells but not in Sertoli cells, whereas its receptors ALK4, ALK7, and ACTR-IIB were detected in Sertoli cells and germ cells, suggesting that NODAL plays a regulatory role in Sertoli cells and germ cells via a paracrine and autocrine pathway, respectively. Human recombinant NODAL could promote the proliferation of human Sertoli cells. The expression of cell cycle regulators, including CYCLIN A, CYCLIN D1 and CYCLIN E, was not remarkably affected by NODAL signaling. NODAL enhanced the expression of essential growth factors, including GDNF, SCF, and BMP4, whereas SB431542 decreased their levels. There was not homogeneity of genes changes by NODAL treatment in Sertoli cells from OA and Sertoli cell-only syndrome (SCO) patients. Collectively, this study demonstrates that NODAL produced by human male germ cells regulates proliferation and numerous gene expression of Sertoli cells.

Abstract
Hua Shou was a very famous physician at the turn of the Yuan and Ming Dynasties. In addition to his medical skills, his social communication was also very helpful to his fame. Under the tutorship of the Confucianist Han Shuo, and physicians such as Wang Jüzhong and Gao Dongyang in his early days, Hua Shou obtained two identities: Confucian scholar and doctor. The former helped Hua Shou get acceptance from literati group, meanwhile, Hua Shou's medical skill helped him deepen the communication among them. By means of his double identity, Hua Shou got acquaintance with many local and nation-wide scholars and politicians, including Zhao Lian, Chen Xingzhong, Wang Shuyu, Fang Guozhen, Song Xuanxi, Zhu You, Wang Xiyang, Song Lian, Liu Ji, through them Hua Shou's fame spread throughout the country. The whole set of"Lin xia"(Hermit identity) constructed by Ding Henian, Liu Renben and Dai Liang, help Hua Shou attain his bequeathed reputation.

Abstract
OBJECTIVE To investigate the prediction value of deceleration capacity of rate (DC) and GRACE risk score for cardiovascular events in AMI patients. METHODS Consecutive AMI patients with sinus rhythm hospitalized in our department during August 2012 to August 2013 were included in this prospective study. 24-hour ECG Holter monitoring was performed within 1 week, and the DC value was analyzed, GRACE risk score was acquired with the application of GRACE risk score calculator. Patients were followed up for more than 1 year and major adverse cardiac events (MACE) were obtained. Analysised the Kaplan Meier survival according to DC and GRACE score risk stratification respectively. RESULTS A total of 157 patients were enrolled in the study (average age: (58.9±12.7)years old). The average follow-up was (20.54±2.85) months. Mortality during follow-up was significantly higher in patients with DC>2.5 compared to patients with DC≤2.5 (P<0.01). In terms of early warning cardiac death, the area under ROC curve of DC risk stratification was 0.898 (95%CI 0.840-0.940, P<0.01), the sensitivity was 84.6%, and the specificity was 84.0%. The area under ROC curve of GRACE risk stratification was 0.786 (95%CI 0.714-0.847, P<0.01), the sensitivity was 84.6%, and the specificity was 74.3%. In terms of early warning cardiac adverse events, the ROC curve of DC was 0.747(95%CI 0.672-0.813, P<0.01), with the 90.0% sensitivity and 67.7% specificity. The GRACE risk stratification was 0.708 (95%CI 0.652-0.769, P<0.01), with the 63.3% sensitivity and 75.6% specificity. Subgroup analysis showed that mortality during follow-up was significantly higher in high risk patients than those with intermediate and low risk patients according to DC risk stratification in intermediate and low risk patients by GRACE risk stratification (P<0.01). CONCLUSION DC could predict cardiac death and MACE in patients with AMI. DC risk stratification is superior to GRACE risk score on outcome assessment in this AMI patient cohort.
