1.The development and innovation of the splenic surgery
Chinese Journal of Digestive Surgery 2016;15(7):655-657
The splenic surgery has a long history of 400 years and the basic principle of selective splenectomy is finally defined.With the enhancement of the notion of preserving spleen and the modifications and improvements of the technology,the splenic surgery has made great progress both in spleen-preserving surgery and splenectomy.For the sake of preserving spleen,innocent splenectomy is avoided as much as possible.Moreover,splenic function is preserved to the largest extent through the substitution of partial splenectomy for total splenectomy or the precise resection of the lesion.On the other hand,in some circumstances,the spleen cannot be preserved.The splenectomy with a series of improvements is very safe in spite of massive splenomegaly.With the development of the technology,the splenic surgery also keeps up with times and continuously innovates.The laparoscopic technology and robotassisted technology bring new energy to the splenic surgery,clinical values of which are being explored and expanded,with a wide development space.

4.Surgical strategy and controversy about upper limit of splenic size for laparoscopic splenectomy
Chinese Journal of Digestive Surgery 2017;16(8):777-781
Laparoscopic splenectomy (LS) is considered as the standard approach for patients with normal-sized or moderately enlarged spleens because of advantages of minimal invasion.With the improvement of laparoscopic techniques,the previous concept that massive splenomegaly (MS) is a contraindication to LS is being challenged.Nevertheless,there is still a tremendous controversy over this issue.(1) Splenomegaly and MS are not clearly defined.(2) The feasibility,safety and postoperative outcomes of LS for MS are fiercely debated despite much improvement of LS for MS.(3) Whether supporting or opposing LS for MS,the core problem that the upper limit of splenic size can be in accord with a requirement of LS is controversial.Taking these issues into account,authors recommended that the splenomegaly shotdd be divided into four degrees rather than three degrees for the sake of guiding the choice of surgery.
5. Effect of ski-siRNA on biological function of human hepatoma cell line HepG2
Academic Journal of Second Military Medical University 2010;29(9):1025-1028
Objective: To design and prepare siRNAs targeting ski gene and to observe its influence on the biological functions of HepG2 cells, such as proliferation, cell cycle, apoptosis, etc.. Methods: Three specific siRNAs of ski were designed and synthesized, and were transiently transfected into HepG2 via cathodolyte liposome transfection method. Real-time PCR and Western blotting were used to measure ski expression at mRNA and protein levels. The cell proliferation was assessed by MTT assay and the changes in cell cycle and apoptosis were evaluated by flow cytometry. Results: All the 3 specific ski-siRNA(A, B, C) effectively inhibited the expression of ski gene, with ski-siRNA-B having the highest inhibition rate(70%). Furthermore, the ski expression had a decreasing tendency with the transfection time. The proliferation of HepG2 cells was markedly inhibited by ski-siRNAs(P<0.05); the number of cells at S stage was obviously decreased, being 2 folds that of the negative control group. Conclusion: The siRNA of ski gene can effectively induce growth inhibition of HepG2 cells and reduce cells of S stage, which is possibly through down-regulation of ski gene.

BACKGROUND: Muscle-derived stem cells have some problems in pudflcation, amplification and directional differentiation during in vitro culture. Basic fibroblast growth factor as a membrane of bloactive factor has been paid great attention, due to its biological activity.OBJECTIVE: To explore effects of basic flbroblast growth factor on/n vitro proliferation of rat musde-derived stem cells.DESIGN, TIME AND SETTING: The cytological in vitro study was performed at the Shenyang Medical College from April to July 2008.MATERIALS: Five healthy male Wistar rats were supplied by Experimental Animal Center, Shenyang Medical College. Basic fibroblast growth factor was produced by Zhuhai Biological Product Co., Ltd.METHODS: Left anterior limb triceps brachii was sterilely obtained from rats. Muscle-derived stem cells were harvested by isolation with enzyme digestion, pudfied by density gradient centrifugation and differential attachment. At the second passage,musde-derived stem cells were treated with basic fibroblast growth factor at final concentration of 6.25, 12.50, 25.00, 50.00,100.00 pg/L. Cells received 200 uL growth medium as blank control group, and those treated with 200 μL growth medium +musde-derived stem celts as negative controls. MTT was added at 24, 48, 72 and 96 hours of culture.MAIN OUTCOME MEASURES: Immunocytochomical method was used to determine rat musde-dedved stem cells. MTT assay was utilized to detect cell proliferation.RESULTS: Musde-denved stem cells were mostly positive for Sca-1, but few was positive for Desmin. Compared with the negative control group, vanous concentrations of basic fibroblast growth factor had significant proliferation effects on musde-derived cells (P < 0.05). At 6.25-50.00 μg/L, the proliferation effect became strong with the increased concentration (P <0.01). At 50.00 μg/L, the proliferation promotion effect nearly reached a peak. Musde-derived stem cells significantly proliferated over time. Compared with the negative control group, significant proliferation promotion effect was detected in the basic fibroblast growth factor groups at 96 hours (P < 0.01).CONCLUSION: Basic fibroblast growth factor can promote proliferation of rat muscle-derived stem cells/n vitro in a dose-time dependent fashion. 50.00 μ g/L and 96 hours are separately good concentration and time for in vitro culture.

Objective To investigate the effects of Oxytocin(OT) on hippocampal long-term potentiation(LTP) and FOS protein expression induced by peripheral stimulation.Methods Single stimulation pulses were delivered to the left sciatic nerves to evoke the field excitatory postsynaptic potentials (fEPSPs) in the right hippocampal CA1. Tetanic stimulation was used to induce hippocampal LTP. Different groups of rat were given NS,OT,Oxytocin antagonist-Atosiban + OT before tetanic stimulation,into lateral ventricle(LV) respectively. Expression of FOS protein was compared among the groups by histopathological and immunohistochemistry. Results Single stimulation evoked fEPSPs in hippocampal CA1,which average latency was (171.9?33.1)ms and average amplitude was (25.7?8.4)?V. Tetanic stimulation induced hippocampal LTP and increased the expression of FOS protein. Intracerebroventricular injection of OT inhibited hippocampal LTP and decreased the expression of FOS protein. This effect of OT was blocked by the pretreatment with Atosiban. Conclusion The results suggested that OT may play an inhibitory role in leaning and memory of rats and the effect is mediated by OT receptor.

Objective To study the pattern of intragastric acid secretion in bleeding ulcer patients to assess the role of gastric acid suppression in the prevention and treatment of ulcer bleeding.Methods 43 cases of peptic ulcer(PU) with ulcer bleeding and 53 cases of age-and sex-matched PU controls without ulcer bleeding were included. All patients received 24 hours gastric pH monitoring. PU was diagnosed by endoscopy. Hp infection was diagnosed by rapid urinase test, biopsy and C 13 breath test.SPSS software was used for statistic analysis.Results In bleeding group, average gastric pH in supine was 1 6,and the percent of accumulative time and the longest lasting time within 0~1 of gastric pH in supine were 21% and 26 0 minutes respectively,while in control group those were 2 0%, 4 5 minutes respectively.However, no differences of gastric pH were found between severe bleeding patients and other bleeding ones. Hp infection rate was 56 1%,54 8% in bleeding group and control group respectively.Conclusions Multiple factors might induce peptic ulcer bleeding. Higher gastric acid secretion at night might be one of the risk factors causing peptic ulcer bleeding.It is suggested that giving PU patients with a high risk of bleeding some acid inhibitor before sleeping may prevent PU hemorrhage. Hp infection may be the direct risk factor leading to ulcer bleeding.
