Objective To explore the relationship between endothelial dysfunction and insulin resistance (IR) during reduction of body weight in obese subjects. Methods 260 obese subjects without metabolic disorders, cardiovascular disease and other clinically detectable diseases were enrolled in this study. Among them 157 patients were found to have impaired endothelial function and 103 with normal endothelial function. They were randomly divided into body weight reduction intervention group and nonintervention group. The measures of intervention included food restriction, exercise, and drugs for weight reduction, and they were continued for two years. 87 subjects with normal weight and without endothelial dysfunction served as normal control. IR index (HOMA-IR) and flow-mediated endothelium-dependent dilatation function were measured before and after the study period. Results After two years, it was found that the endothelial function was markedly improved (4.56?4.79 vs 15.17?5.80, P

Objective To investigate clinical significance of soluble CD30/CD30L and CD40/CD40L system imbalance in ovarian serous tumors.Methods 40 patients of serous cystadenoma and 30 patients of serous cystadenocarcinoma were selected,and 40 age-and weight-matched healthy women were also recruited as the control group.Peripheral venous blood (3 ml) of the healthy control and patients with ovarian serous tumors before surgery and 7 days after surgery were collected.After separation of serum,ELISA was used to detect levels of sCD30,sCD30L,sCD40 and sCD40L.Results Compared to the control group,levels of sCD30,sCD30L,sCD40 and sCD40L in both serous cystadenoma and serous cystadenocarcinoma groups were significantly in creased (P＜0.05).And in those serous cystadenocarcinoma group,levels of such soluble proteins were much higher than in serous cystadenoma group (P＜0.05).7 days after surgery,levels of such soluble proteins were significantly decreased in both serous cystadenoma and serous cystadenocarcinoma groups (P＜0.05).Conclusion Detection of serum sCD30/sCD30L and sCD40/sCD40L is possible to have a certain guiding significance to early diagnosis of ovarian tumors and the prognosis of patients.

Background: There is no gold standard for the diagnosis and monitoring of inflammatory bowel disease (IBD).As immune system plays crucial role in the pathogenesis of IBD,some immune-specific serum antibodies are considered to be useful tools for the diagnosis and differential diagnosis of the disease.Aims: To investigate the clinical significance of serum antibodies,including anti-Saccharomyces cerevisiae antibody (ASCA) and perinuclear anti-neutrophil cytoplasmic antibody (pANCA) in IBD.Methods: Serum samples were obtained from 91 consecutive IBD patients from Feb.2015 to May 2016 at the First Affiliated Hospital of Soochow University.Of them,52 were Crohn's disease (CD) and 39 were ulcerative colitis (UC).Serum samples of 36 non-IBD patients were served as controls.ASCA-IgG and ASCA-IgA were detected by ELISA,and pANCA by indirect immunofluorescence assay.Using clinical diagnosis as gold standard,crosstabs statistics was performed to measure the diagnostic accuracy of ASCA and pANCA,and ROC curve,Pearson Chi-square test and Fisher's exact test were employed for analyzing the correlations of these two serum antibodies with IBD,CD,UC,and the location of the disease.Results: Both serum ASCA-IgG and IgA were correlated with CD (AUC=0.626 and 0.614),while UC was correlated with ASCA-IgA only (AUC=0.486).Serum pANCA had relevance to IBD (r=0.342),CD (r=-0.262) and UC (r=0.614);its sensitivity and specificity for IBD and UC were superior to those for CD (P＜0.05).In CD patients,ASCA-IgG was associated with terminal ileal disease (P＜0.05),and pANCA was associated with colonic involvement (P＜0.05).In UC patients,both ASCA-IgG and IgA were correlated with terminal ileal disease (P＜0.05).Conclusions: Serum ASCA and pANCA may be helpful for discrimination between CD and UC when the diagnosis of IBD is established.Furthermore,they are closely associated with the disease location,ASCA is related with the terminal ileal disease and pANCA is related with colonic involvement.

Objective To investigate the effects of rapamycin which is an autophagy inducer and 3-adenine (3-MA) which is an autophagy inhibitor on motor behavior and autophagy related protein LC3 in C57BL/6 mice of Parkinson's disease(PD).Methods 40 C57BL/6 male mice were randomly divided into control group and experimental groups which consist of MPTP model group,rapamycin group and 3-MA group,with 10 in each group.Mice in experimental groups received intraperitoneal injection with MPTP to establish PD models,and mice in control group received intraperitoneal injection with the same amount of saline solution for 1 week.Mice in rapamycin group received intraperitoneal injection with rapamycin and mice in 3-MA group received intraperitoneal injection with 3-MA at the same time when MPTP was injected.Animal behavior detections were carried out on the 1 th,7th and 14th day after the last injection.After the last injection,mice were sacrificed and sections of midbrain nigra were gained for the detection of expression of autophagy specificity protein LC3 by Western Blot.Results Compared with MPTP model group,rapamycin could improve the general condition and behavioral manifestation of mice in pole test((14.89± 1.14) s vs (16.24±1.39) s,P＜0.05;(15.18±1.36) s vs(17.93±1.11s),P＜0.01),traction test((1.7±0.5) vs (1.2±0.4),P＜ 0.05;(1.5±0.5)vs (1.1±0.3),P＜0.05) and open field test which contained total activity distance((5 875.3 ± 1148.9) cm vs (5 061.5±773.1) cm,P＜0.05;(5 753.2± 1 106.7) cm vs (4 669.3±969.1) cm,P＜0.01) and average speed((19.29±2.35) cm/s vs (16.47±3.01) cm/s,P＜0.05;(18.71±2.71)cm/s vs (15.80±2.50) cm/s,P＜0.01),while 3-MA aggravated behavioral deficits of mice in pole test(19.92± 1.61s vs 17.93± 1.11 s,P＜0.05),and both total activity distance((3 879.7±575.0) cm vs (4 669.3±969.1) cm,P＜0.05) and average speed((13.34± 1.87) cm/s vs (15.80±2.50) cm/s,P＜0.05) in open field test were decreased.The results of Western Blot confirmed that rapamycin could increase the expression of LC3-Ⅱ,however 3-MA could re duce the expression of LC3-Ⅱ.Conclusion This study confirmed that rapamycin could alleviate behavioral symptoms of PD model mice and increase the level of LC3 in midbrain nigra,while 3-MA could exacerbate behavioral symptoms in PD model mice and decrease the level of LC3 in midbrain nigra.Thus it can be speculated that drugs which can regulate autophagy may be potential treatment protocols for PD.

A molecularly imprinted polymer (MIP) using benzoic acid as template molecule, 4-vinyl pyridine (4-VP) as functional monomer, ethylene dimethacrylate (EDMA) as cross-linker, was prepared by bulk polymerization. The needle-type gas concentrator was developed using the MIP as adsorption medium. The device was coupled with gas chromatography (GC) for the analysis of volatile organic compounds (VOCs). The effect of polymerization conditions on adsorption property, such as polymerization time, ratio of the reagents, pre-polymerization time, type of solvents, type of template molecules, has been evaluated. The results of gas chromatographic analysis demonstrated that the optimum conditions for getting the best adsorption performance of the synthesized were polymerization time 6 h at 60 ℃, the ratio of the reagents (template molecule : functional monomer : cross-linker) 1∶ 4∶ 20, pre-polymerization time of 3 h, acetonitrile as solvent, benzoic acid as template.

OBJECTIVE: To describe and analyze the clinical features of nasal respiratory epithelial adenomatoid hamartom and improve the levels of diagnosis and treatment. METHOD: Fourteen cases of nasal respiratory epithelial adenomatoid hamartom confirmed by pathology were collected and analyzed. RESULT: In 14 cases, primary complaint of Hyposmia(or Anosmia)and nasal obstruction were occured in 13 and 11 cases respectively. Four cases had past history of endoscopic sinus surgery because of the diagnosis of nasal polyps. Polypoid neoplasms could be seen in the bilateral olfactory clefts. Sinus CT showed soft tissue shadows in bilateral nasal cavity and mucous membrane thickening in different sinus. Endoscopic sinus surgery were utilized to eliminate focus in all cases. All cases weren t recurred after 2-20 months' following-up visitings. CONCLUSION Nasal respiratory epithelial adenomatoid hamartom is so rare that clinical and pathological doctors have limited knowledge of it. It has its own characteristics from the clinical symptoms, signs to sinus CT although they are nonspecific. So we should improve the understanding about it to avoid misdiagnosis or missed diagnosis.

Objective To analyse the clinical feature of infective endocarditis (IE) in recent years.Methods Clinical profiles including age of onset,predisposing factor,clinical manifestation,blood culture and ultrasonic cardio gram (UCG) of 97 cases from Huashan Hospital in the recent 10 years were collected and analyzed retrospectively. Descriptive data were represented as mean ±standard deviation form.Positive rate was represented as percentage form.Fisher's exact test were used to determine two groups' comparison.Results The mean age of the population was (49±17)years.Seventy-three patients (75.3％) had background heart disease,the top 3 of which was rheumatic heart disease in 27 patients (27.8％),congenital heart disease in 23 patients (23.7％) and idiopathic mitral valve prolapse in 18 patients (18.6 ％).The most common clinical manifestation were fever (99.0％),murmurs (95.9％) and anemia (84.5％).Sixty-six patients (68.0％) had positive result of blood cultures. Streptococcus viridans,which was found in 28 patients with native valve endocarditis (42.4 ％),was still the most common pathogen.Staphylococcus,which was found in 18patients (27.3％),had an elevated ratio.Staphylococcus aureus was found in 10 patients (15.2％)and 3 of which were MRSA.Coagulase-negative staphylococcus was found in 8 patients (12.1 ％ ) and 2 of which were MRCNS. Drug-resistant bacteria was increased and pathogens were varied.Vegetations were found in 79 patients (81.4％) by UCG.ConclusionsClinical manifestation,predisposing factor and pathogen have changed in IE patients. Attaching importance to physical examination,multiple-time blood culture and UCG helps the diagnose of IE.

Objective:To investigate the short-term therapeutic effect and long-term survival of multiple myeloma patients with extramedullary disease (EMD) in the new drug era.Methods:The data of 74 patients with multiple myeloma diagnosed and treated in Anhui Wanbei Coal and Electricity Group General Hospital from January 2015 to January 2020 were retrospectively analyzed, including 17 patients with soft tissue infiltration (EM-S), 9 patients with bone infiltration (EM-B), and 48 patients without EMD (No-EMD). The short-term efficacy, the 4-year progression-free survival (PFS) rate and overall survival (OS) rate, and their influencing factors in three groups of patients after receiving bortezomib regimen were analyzed.Results:After 3-4 courses of early induction therapy of bortezomib regimen, the overall response rate of patients in the EM-S group was lower than that in the No-EMD group and the EM-B group [58.8% (10/17) vs. 85.4% (41/48), 100.0% (9/9)], and the differences were statistically significant ( χ2 = 13.7, P = 0.036; χ2 = 26.5, P = 0.003), while the difference between No-EMD group and EM-B group was not statistically significant ( χ2 = 12.7, P = 0.211). Survival analysis showed that the 4-year PFS rate of No-EMD group was higher than that of the EM-S group and EM-B group (41.0% vs. 7.6%, 0), and the differences were statistically significant ( χ2 = 10.835, P < 0.01; χ2 = 8.276, P = 0.004). Meanwhile, the 4-year OS rate of EM-S group was lower than that of the No-EMD group and EM-B group (16.5% vs. 54.3%, 59.3%), and the differences were statistically significant ( χ2 = 9.146, P = 0.002; χ2 = 4.066, P = 0.044). Conclusion:The early treatment effect of bortezomib regimen, PFS and OS in multiple myeloma patients with EM-S are poor, while the EM-B has no effect on OS.

OBJECTIVETo clone calmodulin (CaM) gene in Eleutherococcus senticosus, and study the effect of endophytic fungi on expression amount of CaM gene.

METHODThe CaM full length cDNA sequence was cloned by rapid amplification of cDNA ends (RACE). The gene was analyzed and corresponding structure and functions were predicted by the bioinformatics methods. The expression amount of CaM gene affected of endophytic fungus P116-1a, P116-1b, P1094 and P312-1 was detected by RT-PCR.

RESULTThe full length of CaM cDNA was 856 bp containing an ORF of 450 bp that encoded a protein of 149 amino acids. The homologous of predicted protein was almost 100% with plants like Panax ginseng and Daucus carota. RT-PCR results showed that endophytic fungus improved CaM expression amount significantly (P<0.05). The highest expression amount of CaM occurred 90 d after reinoculated with endophytic fungi P1094, up to 2.96 times of the control.

CONCLUSIONThe CaM gene of E. senticosus was successfully cloned for the first time. The results demonstrated that endophytic fungus of E. senticosus improved CaM expression amount significantly.
