Objective To explore the effect of ginsenoside Rg1 on proliferation of neural stem cells (NSCs) in vitro. Methods The NSCs cultures were generated from the brain of embryonic day 16 SD rat. Primitive NSCs were cultured, proliferated and passaged. The NSCs were identified by the immunocytochemical (ICC) staining of Nestin. The ICC staining of BrdU was adopted to characterize the proliferation of NSCs. According to limited dilution method, the effect of ginsenoside Rg1 on the proliferation of NSCs was observed. Results The NSCs were successfully cultured and proliferated in vitro. Different dosages (100, 4, 8 ?mol/L) of ginsenoside Rg1 could promote the proliferation of NSCs in vitro. Compared with the control group, the numbers of nerurospheres of the three dosage ginsenoside Rg1 groups (40, 4, 0.4 ?mol/L) were increased obviously. Conclusions Ginsenoside Rg1 significantly promote the proliferation of NSCs in vitro.

Objective To compare the protective effect of colloidal bismuth subcitrate-1 (CBS-1, Lizudele), or colloidal bismuth subcitrate-2 (CBS-2, De-Nol) and sucralfate against gastric mucosal lesion and to investigate their mechanisms. Methods Gastric mucosal injury of rats was induced by ethanol, stress, aspirin and hydrochloric acid. Gastric ulcer was then induced by 50% acetic acid applied to the gastric tunica serosa. We observed the protective effects against gastric mucosal lesion and measured the injury index and the area of ulcer in each group. Statistical t test was used to compare the difference of each group. Results (1)CBS-1, CBS-2, and sucralfate had protective effect against lesions caused by ethanol, stress, aspirin and hydrochloric acid and could promote acetic acid-induced gastric ulcer healing. (2) The mechanisms of protective effect and ulcer healing promotion were that these drugs could increase gastric blood flow and increase activities of QR, GST and GR, and could also promote overexpression of bFGF mRNA and iNOS mRNA. Conclusion Gastric mucosal protective drugs, CBS and sucralfate had effect of resisting injury and promoting ulcer healing. The mechanisms were that they could increase gastric mucosal blood flow and the expression of bFGF mRNA and iNOS mRNA, and reduce oxygen free radical.

Currently,the BCG is used to prevent tuberculosis,but the immune effect is not ideal due to varied reasons.The existence of drug-resistant strains of tuberculosis and the increased prevalence and incidence of AIDS have leaded to the increased incidence of TB year by year.Therefore,the development of new tuberculosis vaccine is imminent In this paper,the latest research results in recent years for tuberculosis live vector vaccines were summarized,which provide a theoretical reference for further research and development of new TB vaccines.

Objective: To study the effect of recombinant human intestinal trefoil factor ( rhITF) on the healing of rat chronic gastric ulcer , protect gastric mucosal and mechanisms are involved. Methods: (1) Acute gastric mucosal injury was induced by ethanol, stress, aspirin and pylorusl ligation. The injury index ,MDA, GMBL,hexosamine (Hex) and acid output were measure. (2) Chronic gastric ulcer was induced in rats by application of 50% glacial acetic acid to the serosa of the glandular stomach. After injury, rats received by rhITF or vehicle orally twice daily for 11 days. On day 12, gastric mucosal blood flow(GMBF)was measured under ether anesthesia. Then the pylorus was ligated for 3 hours and each stomach removed. The gastric acid output, ulcer index, Hex and nitric oxide(NO) content in gastric mucosa, as well as iNOSmRNA in the ulcer bed were determined. Results: (1) rhITF protected gastric mucosa from the acute lesion, and increased Hex content in gastric mucosa. (2) rhITF treatment significantly decreased the ulcer index and gastric acid output, but increased the GMBF, Hex and NO content in comparison with the control groups. In addition, rhITF also stimulated iNOSmRNA expression in the ulcer bed by situ hybridization analysis. Conclusion: rhITF can protect gastric mucosa against acute lesion, and enhance the healing of chronic gastric ulcer in the rats.This action may result from the inhibition of gastric acid output, increase of GMBF.Hex and NO content and rhITF stimulated iNOSmRNA expression.

AIM: To investigate the effects of advanced glycation end products (AGEs) on the expression of plasminogen activator inhibitor-1 (PAI-1) in rat mesangial cells and its relationship with extracellular matrix accumulation. METHODS: Rat mesangial cells were treated with AGE-modified bovine serum albumin or native bovine serum albumin. Normal mesangial cells without any treatments were used as control. Fibronectin (FN), collagen Ⅳ, PAI-1 protein contents were detected by ELISA. PAI-1 mRNA was analyzed by reverse transcriptase-polymerase chain reaction (RT-PCR). RESULTS: AGEs (0-200 mg/L) did not influence mesangial cells proliferation, but stimulated FN , collagen IV and PAI-1 contents in mesangial cell cultured medium in different degrees. AGEs also increased PAI-1 mRNA expression. CONCLUSION: AGEs increase the expression of PAI-1 in rat mesangial cells. AGEs may reduce ECM degradation through increasing PAI-1 expression, which may be one of the mechanisms of ECM accumulation in diabetic nephropathy.

Objective To evaluate the protective effects of hydrotalcite,Marzulene-s,selbex,gefarnate,sucralfate and rebamipide against the gastric mucosa lesions induced by ethanol,aspirin,hydrochloric acid or prednisolone in rats.The changes in intercellular space width of gastric epithelial in rats was observed. Methods Four kinds of models were used to observe the protective effects of six agents against the gastric mucosal lesions.① Ethanol model:a total of 84 male Wistar rats were divided into 7 groups with 12 each. The rats in group 1 to 7 were orally received hydrotalcite,Marzulene-S,gefarnate,sucralfate,rebamipide or normal saline for 3 days,respectively.On day 4,the rats were given 1 ml of absolute ethanol.The length of gastric lesion were measured by ulcer index.② Aspirin model:the rats were received 300 mg/kg of aspirin and 0.1 mol/L hydrochloric acid (0.5 ml/100 g).The following procedures were as ①.③ Hydrochloric acid model:the rats were received 1 ml of 0.7 mol/L hydrochloric acid. The following procedures were as ①. ④ Prednisolone model: all groups were administrated with above 6 agents or normal saline for 5 days.During the 2nd-5th day,the rats were subcu aneously injected with prednisolone (250 mg/kg) daily. Rats were killed on 5th day,and the lesions were mcasured by ulcer index.Gastric mucosal tissue of No.1,5 and ]0 rat in the control group and the hydrotalcite group were picked up to measure the intercellular space width using transmission electron microscopy. Results In four kind of models,the ulcer index were significantly lower in rats treated with mucosal protective agents than that in the controls (P＜0.05),expecially in hydrotalcite group (P＜0.01).The width of intercellular space in the hydrotalcite group was significantly narrower than that in controls (P＜0.05).Conclusions All of the mucosal protective agents can be against the gastric mucosal lesion induced by ethanol,hydrochloric acid,aspirin or prednisolone.Among them,the hydrotalcite is even better.The effect of hydrotalcite is further confirmed by observation of intercellular space width.

The levels of macrophage migration inhibitory factor (MIF) in peripheral blood mononuclear cell (PBMC) and serum in patients with Hashimoto's thyroiditis (HT) were detected by real-time PCR and ELISA,respectively.The results revealed that the expression of MIF mRNA in PBMC ( Z =-4.276,P＜0.01 ) and protein level in serum ( Z=-5.358,P＜0.01 ) were increased in HT patients,and positively correlated with thyroid specific autoantibodies and TSH levels.

ObjectiveTo determine the correlation of human leukocyte antigen-G (HLA-G)expression with CMV active infection after kidney transplantation. MethodsA total of 215 first-time kidney transplantation recipients in one transplantation center were divided into CMV ( + ) group and CMV ( - ) group according to whether they had active CMV infection. mhla-g1 expression on leukocytes was analyzed by flow cytometry. The concentrations of soluble HLA-G5 were detected by using ELISA. The sHLA-G5 cutoff levels by ROC curve was employed to predict the active CMV infection. The expression of sHLA-G5 mRNA and protein in leukocytes was analyzed by using RTPCR and Western blotting respectively. Immunohistochemical staining was used to detect the HLA-G expression in kidney biopsies of 12 cases. ResultsThe expression of mHLA-G1 in peripheral blood was low in both CMV ( + ) group and CMV ( - ) group. Also when CMV-PP65 was positive, there was no significant change in mHLA-G1. In CMV ( + ) group, the proportion of CD14+ mHLA-G1 +cells[(45. 53 ± 17.32)％]in peripheral blood was increased as compared with that in CMV (-)group[(10. 22 ± 5.78)％]. The expression of sHLA-G5 was increased significantly in CMV ( + )group. The optimal cutoff value of sHLA-G5 predicting the active CMV infection was 202. 9 μg/L,with high diagnostic accuracy. HLA-G was positive in the kidney tissue of 10 patients out of 12 patients with active CMV infection. Both RT-PCR and Western blot analysis showed that sHLA-G5 was significantly higher in CMV ( + ) group than that in CMV ( - ) group. ConclusionROC curve analysis of sHLA-G5 with the cutoff value of 202. 9 μg/L can be used to predict the active CMV infection. The HLA-G levels in peripheral blood were significantly increased and HLA-G expression in the tubular epithelial cells of the graft could be a protection mechanism of the kidney function.

Objective To study the correlation of HLA-G levels with acute rejection and CMV active infection post-kidney transplantation.Methods A total of 132 initial kidney transplantation recipients were divided into kidney function stable group (F),acute rejection group (AR),CMV group according to whether they had active CMV infection and acute rejection.Forty-one healthy donors served as control group (H).HLA-G levels and mRNA expression were analyzed by using flow cytometry,ELISA,RT-PCR and Western blotting.Immunohistochemical staining was used to detect the HLA-G expression in kidney biopsies.Results The expression levels of mHLA-G1 were low in all 4 groups pre-transplantation.Only CMV group had significantly more CD14+ mHLA-G1+ cells post-transplantation (P＜0.05).sHLA-G5 levels were higher in F group than in H group (P＜0.05),but there was no significant difference among other groups pre-transplantation (P＞0.05).sHLA-G5 levels were increased significantly in CMV group as compared with F group (P＜0.05),and those in F group were higher than in H and AR groups (P＜0.05).Renal tissue biopsies from 21 renal transplantation recipients with AR indicated that HLA-G5 was expressed negatively in 17 patients,positively in 3 patients and 1 weakly positively.HLA-G was positive in the kidney tissue of 9 patients out of 9 patients with active CMV infection.In total 132 recipients,AR incidence was significantly lower in CMV ( + ) group (7.1 ％,2/28) than that in CMV ( - ) group (24.0 ％,25/104).Conclusion The sHLA-G5 may contribute to predict AR and CMV active infection; AR and CMV active infection may be correlation with immune balance in kidney transplantation recipients.
