Glycyrrhiza uralensis Fish Polysacchoride(GPS)was observed to have mitogenic activity on murine spleen cell proliferation in vitro,The results showed that this mitogenic activity of GPS may be directed to B Iymphocytes,i.e.GPS is a new mitogen of murine B lymphocytes.Furthermore,it was found that B lymphocytes stimulated by GPS was M? depedent and T cell-indepedent.On the contrary,antibodies and IL-2 production was inhibited by GPS in vivo.

Objective To establish a rat model of pulmonary hypertension induced by left-to-right shunt and explore the influence of high pulmonary blood flow on pulmonary vascular collagen remodeling.Methods Abdominal aorta and inferior vena cava shunting was produced in rats. Pulmonary artery meanpressure (PAMP) of each rat was measured by using a right cardiac catheterization.Pulmonary artery collagen Ⅰ and Ⅲ were detected using immunohistochemisty.Results After 11 weeks of shunting the Qp/Qs was 3.3∶1.0,indicating a large shunt. Pulmonary artery mean pressure was increased as compared with controls[(23.0?0.9) mm Hg vs (15.7? 1.1) mm Hg,P

Diabetes mellitus has became a growing public health problem,its acute and chronic complications threaten the patient's dramatically.HbA1c is recognized as the gold standard for blood glucose evaluation in patients with diabetes It has reported that the incideut rafe of diabetes related will decline remarkably when HbA1c decline by 1％,so the detection accuracy of the HbA1c is very important in the diabetes patient's management.Uncertainty of measurement can reflect the detation accuracy,which will benifite the value of HbA1c.

Objective To know the status of microbial contamination in filtrated water and edible ice used in food processing,and to provide experimental basis for the management of HACCP of filtrated water and edible ice. Methods The samples of water and ice were collected from a western style restaurant in Changchun. The microbial indicators were tested based on Standard Examination Methods for Drinking Water(2001). Results Results In the third quarter, 37.8%, 32.4%, 13.5% of total bacterium counts, total coliform counts, feces coliform counts of the water samples was unqualified. Conclusion The filtrated water and edible ice used in restaurants can be contaminated by microbes in degree. It is necessary for HACCP of filtrated water involved coliform counts contamination to carry out dynamic monitoring.

Objective: To search for new compounds with better water-solubility and higher antianxiety activities. Methods: A series of 2-arylimidazo[1,2-a] pyridine-3-acetamide derivitives were designed and synthesized. The anxiolytic activities were evaluated by BZDR competitive binding assay in vitro and the elevated-plus maze test in mice, the structure-activity relationship (SAR) has been studied. Results and Conclusion: Twenty-eight new compounds have been synthesized. Their structures were confirmed by 1H NMR and MS. According to the results of BZDR affinity test, compounds I1, I 8, I10, I13, I19 showed as good affinity as the positive control (Ro5-4864). The corresponding inhibition was 87%, 89%, 85%, 89% and 76% respectively at the concentration of 100 nmol/L, while that of Ro5-4864 was 82%. I8 and I10, which display better water-solubility and better BZDR affinity in vitro, show significant antianxiety effects in vivo.

AIM: To compare the effects of different surgeries in the treatment of angle closure glaucoma with cataract and the improvement of quality of life.METHODS: The clinical data of 60 cases (60 eyes) with angle closure glaucoma and cataract who were admitted to the hospital between January 2014 and October 2016 were collected.According to the surgical method, they were divided into the control group (simple trabeculectomy, n=28) and the observation group (trabeculectomy combined with phacoemulsification and intraocular lens implantation, n=32).The changes of visual acuity and intraocular pressure before and after surgery were compared between the two groups.The incidence of postoperative complications was statistically analyzed, and the quality of life was compared between the two groups.RESULTS: Before surgery, there was no significant difference in visual acuity, intraocular pressure and anterior chamber depth between the two groups (P>0.05).At 4wk after surgery, the visual acuity of two groups increased and intraocular pressure decreased.The anterior chamber depth of observation group increased while that of the control group decreased (P<0.05).At 4wk after surgery, the visual acuity and anterior chamber depth of observation group were higher than that of the control group but intraocular pressure was lower than that of control group (P<0.05).The success rate of surgery and the opening rate of chamber angle after surgery in the observation group were higher than those in the control group (P>0.05).The incidence of postoperative complications in the observation group was lower than that in the control group (P<0.05).Before surgery, there was no statistically significant difference in quality of life score between the two groups (P>0.05).At 4wk and 3mo after surgery, the scores of the two groups increased (P<0.05), and the quality of life scores of observation group were higher than those of the control group at different time (P< 0.05).CONCLUSION: The success rate of trabeculectomy combined with phacoemulsification and intraocular lens implantation is high in the treatment of angle closure glaucoma with cataract.The regimen can improve the visual function, reduce the incidence of postoperative complications, and improve the quality of life of patients.

Background Epithelial-mesenchymaltransition (EMT)isamajorcontributortothe pathogenesis of posterior capsular opacification(PCO).Kruppel-like factor 6 (KLF6) is a zinc finger protein,which can be stimulated by high glucose in proximal tubule cells and involved in transforming growth factor beta (TGF-β)induced EMT of diabetic nephropathy.ObjectiveThis study was designed to investigate the effect of high glucose on the expression of KLF6 and its target genes( TGFB1,TGFBR1,COLIA1,HSP47) in human lens epithelial cells (LECs).MethodsHuman LECs(SRA01/04) were cultured and exposed to different concentration of glucose.The expressions of KLF6 mRNA and protein were analyzed by real time polymerase chain reaction( real time PCR) and western blot after treatment with high glucose.The expressions of KLF6 target genes were analyzed by real time PCR to evaluate the EMT of SRA01/04 cells.ResultsCompared with the control group(5.5 mmol/L),the relative mRNA levels of t-KLF6 and wt-KLF6 in SRA01/04 treated with high glucose(22.2,44.4,66.6 mmol/L) increased obviously (F =72.53,42.02,P＜0.01 ).Then,the concentration of 22.2 mmol/L was used in the next experiments.The relative mRNA levels of t-KLF6 and wt-KLF6 increased to the peaks after treatment with high glucose for 12 h,and began to decrease after 24 h until lower levels after 48 h ( F =100.12,125.52,P ＜ 0.01 ).Western blot showed that the expression of KLF6 protein was also upregulated by high glucose treatment.With the promotion of the expression of KLF6 gene,the relative mRNA levels of TGFB1,TGFBR1,COLlAl and HSP47 of treated cells also respectively increased after treatment for 12 h,and began to decrease after 24 h until nearly at the levels of the control groups after 48 h( F=6.73,162.35,64.39,12.05,P＜0.05 ).ConclusionsIt was concluded that high glucose induced the expression of KLF6 in human LECs,and KLF6 transiently stimulated the expression of target genes TGFB1,TGFBRl,COLlAl and HSP47 which were mainly involved in the mechanism of EMT.
