Pancreatic neuroendocrine neoplasm: experience of individual laparoscopic pancreatectomy / 中华内分泌外科杂志

Objective To study the feasibility and safety of individual laparoscopic pancreatectomy for patients with pancreatic neuroendocrine neoplasm(pNEN).Methods 16 patients with pNEN admitted from Jan.2007 to Nov.2016 undergoing individual laparoscopic pancreatectomy were retrospectively analyzed.Results The operations were successfully accomplished in all the 16 patients,including 2 cases of local excision,2 cases of bundling method excision,2 cases of central pancreatectomy and pancreaticojejunostomy,4 cases of spleen-preserving distal pancreatectomy and 6 cases of distal pancreatectomy combined with splenectomy.The operation time was ranging from 60 to 260 mins,and the blood loss was from 50 to 300 ml.Three cases suffered from level A postoperative pancreatic leakage.The cases of grade G1,G2,G3 were 10,5,1,respectively.The follow-up period was from 3 to 121 months.One case of grade G2 died 46 months postoperatively and 1 case of grade G3 died 36 months postoperatively.Conclusion Individual laparoscopic pancreatectomy is safe and feasible for early pNEN.

Development on research of acupuncture effects on microcirculation / 中国针灸

The Chinese and English published literature regarding the effects of acupuncture on microcirculation in recent years were analyzed, and it was found out that the theory of TCM meridian had subtle connection with microcirculation on structure and function, which could provide a possible breakthrough for the research of meridian essence. Acupuncture, through multiple links, multiple paths and multiple levels, could regulate microcirculation under physiological or pathological condition, which was a bidirectional benign adjustment function, and reflected the characteristic of acupoint specificity. Due to many shortcomings in the current studies, studies with rigorous design, large sample size and multicenter are expected in the further to make a standard systematized research.

Effect of Electroacupuncture at Point Zusanli (ST36) on Gastric HSP70 mRNA in Rats with Stress Gastric Ulcer / 上海针灸杂志

Objective To investigate the effect of electroacupuncture at point Zusanli (ST36) on gastric expression of heat shock protein 70 (HSP70) mRNA in rats with stress gastric ulcer and explore the molecular mechanism of its prevention and treatment of gastric ulcer. Method Fifty-one SD rats were randomly allocated to normal control (normal), stress gastric ulcer (model) and electroacupuncture at point Zusanli (electroacupuncture) groups. A model of stress gastric ulcer was made by cold restraint. From the second day after model making, the electroacupuncture group received electroacupuncture at point Zusanli 20 min once daily for three consecutive days, with left and right points Zusanli alternately needled; the model group, the same restraint treatment as in the electroacupuncture group; the normal group, no treatment. Gastric mucosal ulcer index (UI) was calculated using the GUTH’s method. The pathological morphology of gastric tissue was observed by HE staining. Gastric HSP70 mRNA expression was determined by RT-PCR. Result Different numbers and sizes of obvious gastric mucosal ulcers were observed, UI increased significantly (P<0.001) and HSP70 mRNA expression decreased significantly (P<0.05) in the model group compared with the normal group. The pathological change in gastric tissue improved somewhat, gastric mucosal UI decreased significantly (P<0.05) and HSP70 mRNA expression increased significantly (P<0.01) in the electroacupuncture group compared with the model group. Conclusion Electroacupuncture at point Zusanli can upregulate gastric HSP70 mRNA expression and promote the repair of gastric mucosa injuries in rats with stress gastric ulcer.
