Objective To investegate the effect of ginsenoside Rg1 on the apoptosis related protein FLICE-inhibitory protein(FLIP),Fas-associated death domain protein (FADD)and Caspase-3 in the subatania nigra(SN)of 1-methyl-4-phenyl-1,2,3,6-tetrahyd-ropyridine (MPTP)-induced mouse models of Parkinson’s disease(PD), and to investigate the role of FADD and FLIP in the pathogenesis of PD and the protective effect of ginsenosides Rg1 on dopaminergic neurons.Methods 45 C57BL/6N mice were randomly divided into control group,model group and ginsenoside Rg1 group (n=15).The mice in model group were injected with MPTP by intraperitoneal,the mice in Rg1 group were injected with ginsenoside Rg1 before injecting MPTP,and the mice in control group were injected with normal saline by intraperitoneal. The behavioral changes of the mice in various groups were observed, and immunohistochemistry and Western blotting methods were used to observe the expressions of tyrosine hydroxylase (TH),FADD,FLIP and Caspase-3 in substantia nigra of the mice.Results Compared with control group,the mice in model group presented with typical symptoms of PD, the TH-positive neurons in the subatania nigra was significantly reduced (P<0.01 ), the number of FADD, FLIP and Caspase-3 positive cells was significantly increased(P<0.01),and the cytoplasm was deeply stained;the protein expression levels of FADD,FLIP and Caspase-3 were significantly increased (P<0.01).Compared with model group,the PD symptoms of the mice in ginsenoside Rg1 group reduced, the number of TH-positive neurons was significantly increased, the number of positive cells of FLIP,FADD and Caspase-3 were significantly reduced(P<0.01),and the cytoplasm was lightly stained;the protein expression levels of FADD, FLIP and Caspase-3 were significantly reduced (P<0.01 ). Nonlinear correlation analysis found that there was a positive relationship between the number of FADD and Caspase-3 positive cells (r=0.791,P<0.05).Conclusion Ginsenoside Rg1 may play a neural protective effect dopaminergic on neurons by modulating the FADD and FLIP expressions in SN of PD model mice.

Objective To explore the the influence ofFurong-Tongmai capsules on myocardial expression of LN and CollagenⅢ in diabetes mellitus (DM) rats.Methods A total of 60 rats were randomly divided into the control group, the model group, the low-, middle- high-dosageFurong-Tongmai capsules group (n=10). The low-, middle-high-dosageFurong-Tongmai group was given 1.4, 0.7, 2.8 g/(kg body weight) Furong-Tongmai capsules. The other two groups were given the same dose of purified water. After 8 weeks treatment, the myocardial was taken to make pathology slice with SP immunohistochemistry staining. The expression of LN and CollagenⅢ were detected.Results Compared with model group, the expression of LN (0.67% ± 0.04%,0.65% ± 0.09%vs. 1.08% ± 0.13%) and CollagenⅢ (0.67% ± 0.15%, 0.69% ± 0.13%vs. 1.17% ± 0.12%) in the middle-high-dosageFurong-Tongmai groups significantly decreased (P<0.05). However, there were no statistical differences between the low-, middle- high-dosageFurong-Tongmai groups and the model group (P>0.05).Conclusions TheFurong-Tongmai capsules could inhibit the expression of LN and CollagenⅢ in DM rats.

Objective To explore the CT manifestations of non-functional islet cell tumor(NFICT)Methods The findings of plain and enhancement CT scanning from 17 cases with NFICT,which were confirmed by the surgeries and pathological sections,were analyzed retrospectively.Ninty ml of non-ioniodine contrast reagent with 3ml/s injection flow rate was employed as the enhancer for measuring the arteriovenous double phase CT value of the pancreas and tumor.Results Tumors were found in all the cases who received CT scan.Compared with pancreatic substance in the CT plain scan,tumors with low density were found in 2 cases,tumors with mixed low density in 11 cases and tumors with isodensity in 4 cases.Local calcification in tumor was found in 5 cases.Various degrees of strengthening were showed in 17 cases with enhancement scanning.Obvious enhancement in arterial phase presented in 5 cases,moderate enhancement in 6 cases and slight enhancement in 6 cases.Conclusions CT plain scan of NFICT shows that the tumor margins are clear and some tumors have calcification.All tumors in the CT enhancement scanning show various degrees of enhancement,the persistent enhancement from arterial phase to portal vein phase is the characteristic manifestation of NFICT.

BACKGROUND: One of mechanisms involved in treating cerebral ischemia with bone marrow mesenchymal stem cells (BMMSCs) implantation is paracrine action. However, few studies have reported this mechanism.OBJECTIVE: To observe the inhibitory effect of BMMSCs paracrine action on apoptosis and its mechanism after cerebral ischemia. METHODS: BMMSCs were isolated from rats with adherent culture. Rat cerebral ischemia model was established by the middle cerebral artery occlusion. A total of 24 rats were divided into 4 groups, with 6 animals in each group. Cell implantation medication group: rats were received U0126 medication after BMMSCs implantation; Non-implantation medication group: rats were received U0126 medication after PBS injection; Cell implantation control group: received solvent medication after BMMSCs implantation; Non-implantation control group: received solvent medication after PBS injection. At 7 days after operation, the expressions of vascular endothelial cell growth factor (VEGF) and p-ERK1/2 protein were measured by Western blot analysis, and the apoptosis cells in the area of ischemic penumbra and cortex were examined by TUNEL. RESULTS AND CONCLUSION: The VEGF protein content in the brain tissue was significantly greater in the cell implantation groups than that of the non-implantation group, with increased p-ERK1/2 and decreased apoptosis cells. The expression of p-ERK1/2 was down-regulated in rats which were administrated U0126 while the number of the apoptosis cells was increased, but the VEGF protein expression had no statistical difference. It suggested that BMMSCs can paracrine VEGF in the striatum of brain and play an inhibitory effect on apoptosis in the ischemia area via activating ERK1/2.

Objective To evaluate the clinical effectiveness of laparoscopic (LDP) versus open distal pancreatectomy (ODP) using meta-analysis.Methods Comprehensive literature search was conducted on articles only in English published from 2006 to 2012 on MEDLINE,EMbase,Cochrane Central Registry of Controlled Trials to compare LDP with ODP for Pancreatic disease.Data were extracted and evaluated by two reviewers independently.The quality of the included trials was evaluated.Meta-analyses were conducted using the Cochrane Collaboration's RevMan 5.1 software.Results Fourteen controlled clinical trials (n=1417) were included.The LDP group was significantly longer than the ODP group in operation time,and was significantly larger in the number of patients with spleen preservation [(MD-273.10,95％ CI-354.39-191.081,P＜0.01),(OR 2.42,95％ CI 1.78-3.30,P＜0.01) respectively].The LDP group was significantly less than the ODP group in intraoperative blood loss,time to oral intake,and length of hospital stay [(MD-273.10,95％ CI -354.39-191.81,P＜0.01),(MD-1.78,95％ CI-2.36-1.20,P＜0.01),(MD-3.15,95％ CI-3.97-2.33,P＜0.01) respectively].There were no significant differences in blood transfusion,pancreatic fistula rate,and mortality between the two groups.Conclusions LDP is feasible and safe in treating pancreatic disease.When compared with ODP,LDP has the advantages of having less intraoperative blood loss,quicker recovery and more patients with spleen preservation.
