Objective To evaluate the pancreaticojejunostomy procedures selection strategy after pancreaticoduodenectomy.Methods The clinical data of 305 cases who received pancreaticoduodenetomy at Shanghai Renji Hospital from Jan 2010 to Jan 2013 were retrospectively analyzed.For patients with pancreatic duct diameter≥3 mm,duct-to-mucosa pancreaticojejunostomy was applied(120 cases).For duct diameter ＜ 3 mm,modified Child pancreaticojejunostomy was applied to 80 cases when pancreatic stump was large,or binding pancreaticojejunostomy procedures was applied to 105 cases while pancreatic stump was small.Results The diameter of the pancreatic stump in modified Child group was significantly larger than that in the binding group (F =5.78,P ＜ 0.05).The overall incidence of pancreatic fistula was 11.1％ (34/305).There were no significant differences in the incidences of pancreatic fistula,peritoneal bleeding,abdominal infection,digestive dysfunction rate,the mean duration of hospital and the death cases among the three groups (x2 =1.51,2.78,1.16,3.75,1.94,F=2.13,P＞0.05).Conclusions Three different pancreaticojejunostomies based on the size of pancreatic duct and pancreatic stump are equally safe and effective as a reconstructive method after pancreaticoduodenectomy.

BACKGROUND: The source of bone marrow mesenchymal stem cells (BMSCs) is limited, and the cellular morphology,proliferation and multi-directional differentiation capacities can vary during serial passages in BMSCs in vitro.OBJECTIVE: To study the effects of fibroblast growth factor (FGF) on cellular morphology, proliferation and differentiation of serially passaged BMSCs.METHODS: (1) BMSCs were isolated from Sprague-Dawley rats and cultured. These cells were passaged six times in vitro, and the cellular morphology was observed and photographed. (2) BMSCs at passage 6 were seeded into 96-well plates and randomly divided into control group and FGF treatment group. The proliferation of cells in both groups was detected with cell counting kit-8 kit at days 1, 2, 3, 4, 5, 6, 7 after culture. (3) BMSCs at passage 6 were seeded into 6-well plates and randomly divided into control group and FGF treatment group. After 7 days treatment with growth medium or growth medium containing FGF, the cellular morphology was observed and photographed. And then the cells of both groups were treated with osteogenic induction medium, adipogenic induction medium and chondrogenic induction medium for the next 7 days. The osteogenic, adipogenic and chondrogenic related genes (RUNX2, ALP, OCN;PPARγ2, AP2, ADIPOQ; SOX9, collagen II, aggrecan) were detected with real-time PCR. The protein expressions of RUNX2, PPARγ2, SOX9 were detected with western blot assay. (4) BMSCs at passage 6 were seeded into 6-well plates and randomly divided into control group and FGF treatment group. After 7 days treatment with growth medium or growth medium containing FGF, the cells were cultured with osteogenic induction medium, adipogenic induction medium and chondrogenic induction medium for the next 14 days. Then, alizarin red S staining, oil red O staining and alcian blue staining were performed.RESULTS AND CONCLUSION: (1) After in vitro passage for six times, the cellular morphology changed obviously, and FGF treatment recovered the characteristics of primary cells. (2) Compared with the control group, the cell proliferation in the FGF treatment group was significantly increased (P < 0.05). (3) Compared with the control group, the expression of osteogenic, adipogenic and chondrogenic related genes (RUNX2, ALP, OCN; PPARγ2, AP2, ADIPOQ; SOX9, collagen II, aggrecan) was increased significantly in the FGF treatment group (P < 0.05). The protein expressions of RUNX2,PPARγ2, SOX9 were also higher in the FGF treatment group than the control group (P < 0.05). (4) Compared with the control group, the number of extracellular calcium nodules, the number of intracellular lipid droplets, and the expression of acid acidic mucopolysaccharide were significantly increased after FGF pretreatment. To conclude, FGF pretreatment can preserve the stemness of BMSCs serially passaged in vitro.

ObjectiveTo demonstrate the effect of moderate hypothermia and doule carotid ice applied to acute intracerebral hemorrhage (ICH) and the best opportunity of treatment.Methods174 cases with ICH were randomly divided into treated group and control group, 87 cases for each group. Each case of both groups was treated by routine therapy, moreover, all cases in treated group were treated by moderate hypothermia (MHT).The clinical effect and prognosis between treated group and control group were contrasted,so to do between the cases in the treated group who were treated no more than 3 hours and more than 3 hours after attack.ResultsCompared with the control group, the neurological function improved in the treated group(P<0.05), as well as survival rate and recovery(P<0.05).Cases who treated no more than 3 hours after attack was better than that of more than 3 hours(P<0.05).ConclusionModerate hypothermia can effectively ease the neurologic deficits after ICH, decrease mortality and disable rate.The best therapy time is within 3 hours after ICH.

OBJECTIVETo investigate the effect of Jiangtang Yishen Recipe (JTYSR) on high insulin induced cell proliferation of human glomerular mesangial cells (HMCs) and the expression of insulin receptor substrate 1 (IRS-1) and phosphatidylinositol-3-kinase (PI-3K).

METHODSHMCs were divided into 4 groups, i.e., the negative control group, the high insulin model group, the JTYSR group, and the LY294002 group. The concentration of insulin, JTYSR, and LY294002 was respectively confirmed by pre-experiment. Different culture solution was respectively added for different groups. RPMI1640 culture solution was added for HMCs in the negative control group, while HMCs in the rest 3 groups were cultured by 100 nmol/L insulin for 24 h. Meanwhile, HMCs from the JTYSR group and the LY294002 group were exposed to 125 mg/L JTYSR and 80 micromol/L LY294002 respectively for further 48 h. The proliferation of HMCs was detected by MTT and flow cytometry. The protein expression of IRS-1 and PI-3K in HMC was detected by immunohistochemical assay and Western blot. Results The proliferation of HMCs induced by high insulin could be significantly lowered, and the protein expression of IRS-1 and PI-3K could be down-regulated in the JTYSR group and the LY294002 group (P <0.01). Compared with the LY294002 group, the protein expression of IRS-1 and PI-3K could be slightly down-regulated in the JTYSR group (P <0.05).

CONCLUSIONJTYSR could lower high insulin induced proliferation of HMCs, and its mechanism might be related to insulin signaling pathway.
