Objective To investigate the safety and feasibility of laparoscopic pancreaticoduodenectomy (LPD). Methods Clinical data of 9 patients who underwent LPD operation from September 2014 to February 2017 in the first hospital of Shanxi Medical University were analyzed retrospectively. Results 9 patients attempted LPD, while one required conversation to open procedure. Two cases underwent hand assisted laparoscopic surgery .The average operative time was (553 ± 86.1) minutes, the average amount of bleeding was (333.3 ± 304.1) ml, and the average hospitalization time after operation was (25.3 ± 8.9) d. Postoperative bowel sound recovery time was (3.5 ± 1) d. Postoperative complications included pancreatic leakage in 4 cases (A grade pancreatic leakage in 1 cases, B grade in 3 case), lymph leakage in 1 case, abdominal hemorrhage in 1 case , gastric emptying in 2 cases , and bile leakage in 1 case. All patients with postoperative complications were cured by non operative treatment. Postoperative pathological examination showed that 5 cases had duodenal papillary adenocarcinoma, 1 case had pancreatic ductal carcinoma, 2 cases had common bile duct disruption differentiation of carcinoma, and 1 case had pancreatic head retention cyst. Patients were followed up 3 to 24 months after operation. 1 case of pancreatic duct died 17 months after operation. One case of middle bile duct carcinoma 12 months after surgery had liver and retroperitoneal lymph node metastasis. The remaining 7 cases had no complications. Conclusions laparoscopic pancreaticoduodenectomy is minimally invasive, safe and feasible.

Objective:To study the pathogenetic mechanism of intestinal injury in the aged rat with pneumonia and the effect of Dusuqing(毒素清) on it.Methods:The models of rats with Escherihia coli pneumonia were duplicated and divided into aged control group(ACG),aged model group(AMG),high doses group(HDG) and low doses group(LDG) of Dusuqing and norfloxacin group.The pathological changes in lung tissue and intestine,the contents of intestinal 6-keto-prostaglandim F1α(6-keto-PGF1α),thromboxane B2(TXB2),nitride oxide(NO),malondialdehyle(MDA) and the activity of superoxide dismutase(SOD) were observed.Results:The lung and intestinal injury in AMG was more serious.The decrease of SOD activity and 6-keto-PGF1α content,the increase of content of TXB2,NO,MDA in the AMG were more significant than those in the ACG.In comparison with those in the AMG,the level of SOD activity,6-keto-PGF1α content were increased,otherwise the contents of MDA and NO were decreased in the HDG,the LDG and the norfloxacin group.Conclusions:The injury mediated by prostaglands and free radical is related to the occurance and development of damage of intestinal tissue with pneumonia. Dusuqing is able to improve this damage obviously in aged rats with pneumonia and the mechanisms and regulation of prostaglands metabolism.

Induced pluripotent stem cell (iPS cell) opened a new way to stem cell research,iPS cells can differentiate into hepatocytes in vitro gradually,this breakthrough makes the iPS cells have become a promising clinical application source.During the process of iPS cells to hepatocytes,a variety of cytokines regulate gene expression by coordinating various liver cell growth signal to promote iPS cells into hepatocytes differentiation and maturation.This article summarizes the relevant cytokines and their role in iPS cells in hepatocytes differentiation.

Anterior ischemic optic neuropathy (AION) is the ciliary artery-circulatory disorders for the supply of optic nerve head area before the sieve plate prozone and sieve plate district, result in the insufficient blood supply of the optic nerve head and ischemia hypoxia, edema. Clinical manifestations of the type with non-artery inflammatory neuropathy and artery inflammatory neuropathy, which would both eventually lead to the irreversible damage to the optic nerve. In the early phase of AION, the main method is giving a glucocorticoids intravenous drip and a periglomerular injection (or retrobulbar injection) in time, but using the glucocorticoids for a long time or in quantity can cause a series of complications. Therefore, the combination of traditional Chinese and western medicine treatment of AION has become more and more significant in clinic.

AIM\ To study the protective mechanism of ligustrazine(LT), shenmai injection(SI), combination of ligustrazine and shenmai injection (LSI) to injury of kidney after brain ischemia reperfusion in aged rats from the free radical change. METHODS Aged rats (more than 20 months) were divided into model group (Aged model), control group(Aged control), nimotop group(NG), ligustrazine group(LG), shenmai injection group(SIG) and LSI group(LSG). The following items was measured in aged rats with 60 min reperfusion after 30 min brain ischemia: the content of creatinine(Cr), urea nitrogen(BUN), MDA and the activitiy of superoxide dismutase(SOD). RESULTS The distinct pathological and functional injury in the kidney was found in the models, and this change was alleviated in each treatment group. The increase of MDA content in the models kidney tissue was obvious than that in the controls. The MDA level in the LG and the SIG was decreased. CONCLUSION The kidney injury after brain ischemia reperfusion in aged rats is correlated with the injury of free radical. LT, SI ,LSI and nimotop alleviate this injury. LT and SI restraine the injury of lipid peroxidation, this may be one of the mechanisms of restraining kidney injury after brain ischemia reperfusion.
