Central pancreatectomy is an ideal surgical procedure for the treatment of benign or low-grade malignant tumors in the pancreatic neck or the proximal body of the pancreas,and it can preserve more normal pancreatic tissue in order to reduce the incidence of endocrine and exocrine insufficiency after surgery.Although some clinical studies have demonstrated the feasibility and safety of this procedure,laparoscopic central pancreatectomy was technically challenging with a few number of cases.This article reviews the current status of laparoscopic central pancreatectomy and introduces our clinical experience of laparoscopic central pancreatectomy and pancreaticojejunostomy.

Peritoneal adhesion is one of the common complications of abdominal and pelvic operations,the impact of which is immense in terms of human suffering and substantial socio-economic burden.There is an urgent need for a more effective understanding of the disease process and its etiology,to evaluate the pharmacologic,mechanical,and surgical adjuvant strategies to minimize peritoneal adhesion formation.

WTBZ]Breast cancer resistance protein (BCRP) is a recently discovered half-transporter belonging to the ABC transporter superfamily as P-glycoprotein(P-gp) and multiple resistance protein (MRP). The latest research results concerned BCRP on construction features of gene, relationship to differentiation of hemopoietic stem cell and correlated transport substrates were reviewed in the article and it's clinical significance was mentioned at the same time.

The levels of platelet-activating factor (PAF) in cerebrospmal fluid (CSF) of patients with acute cerebral infarction were measured by the method of PAF-induced platelet aggregation quantitative analysis. The results indicated that the levels of PAF in CSF of patients with acute cerebral infarction were significantly increased (P

Gastrointestinal tumors are the major disease that threaten human health.According to statistics,more than 700 000 people died every year because of gastric cancer,1/10 of all cancer mortality.Colorectal cancer incidence of malignant tumors,which ranked third,ranked fourth in cancer deaths.At now the treatment of gastrointestinal tunors mostly are operation,radiotherapy and chemnotherapy,but to spread of tumors,doctors still haven' t more better method.Nanoparticles have properties in the diagnosis and treatment of cancer,including their size-dependent properties,stability in solvent,ideal size for delivery within the body,and tunable surface chemistry for targeted delivery.Here,the author do an overview of nanoparticles in gastrointestinal tumors ablation.

Objective To investigate the current situation in construction of WeChat public platform in 9 class A hospitals affiliated to Sichuan Province in Chengdu. Methods The problems and the reasons why they occurred in construction of WeChat public platform in these 9 hospitals were analyzed by literature analysis, interview, Topsis and RSR analysis, and their combination. Results The problems found in hospital WeChat public platform included imperfect management, unmatched construction level and hospital scale, insufficient government policy support and effective supervising mechanisms. Conclusion Hospitals should strengthen the construction and management of their WeChat public platform, innovatively construct their WeChat public platform, win over sufficient government policy support, and improve their supervising mechanisms.

Sepsis is a common acute systemic infection,severe sepsis has a high rate of mortality,and its incidence rate is rising year by year.Due to the overproduction of free radicals in sepsis,microcirculation blood is drived disorder,multiple organ function can be impaired.This review describes the role of ascorbic acid in sepsis patients,which can reverse the oxidative stress injury rapidly through an eNOS-dependent mechanism,resisting platelet adhersion,preventing capillary embolism,resevering microcirculation blood flow,so as to improve patients' survival.

Tissue was obtained from 14 aborted human fetuses, ranging from 13-32 weeks of gestation (wg). The crown-rump length (CR) ranged from 8.3-33 cm. Frontal sections of the specimens were prosessed for SEM and observation were focused on the areas adjacent to the middle part of the calcarine fissure.At 13 wg (CR 8.3 cm), the visual cortex (area 17) was composed of five zones: viz., the ventricular zone, the subventricular zone, the intermediate zone, the cortical plate and the marginal zone. These five zones showed a series of transformations with increasing age. 1) The ventricular zone became progressively thinner, mitotic activity of the ventrieular cells decreased progressively and finally the ventricular ceils differentiated into a single layer of ependymal cells. 2) The subventricular zone and the inter mediated zone were replaced by fiber bundles of white matter. 3) The cortical plate increased in width, exhibited the greatest growth rate, and became differentiated. At 21 wg (CR 20cm), the lower part of the cortical plate first gave rise to laminae VI and V. At 23 wg (CR 22cm), lamina Ⅳ was established in the middle part of cortical plate. At 26 wg (CR 25cm), laminae Ⅲ and Ⅱ could be identified in the upper part of cortical plate. 4) The marginal zone transformed into lamina Ⅰ at its original site.

Three key ethical issues in neurotherapeutics research are discussed: the ethical challenges arising from changes in the financial incentive of researchers and their institutions,risk-benefit analysis on testing innovative interventions,and the research for informed consent.

Objective To isolate and culture rats liver KCS ,and to explore the effect of IRE1-XBP1 pathway on regulation of polarization in activated Kupffer cells (KCs) .Methods (1)Rat KCs were isolated by Ⅳ type collagenase digestion and gradient cen-trifugation methods .(2)KCs were transfected and randomly divided into four groups :XBP1-shRNA group ,Ctrl-shRNA group , AdV-XBP1 group and Ctrl-AdV group .(3)The transfection level of KCs XBP1 ,IL-6 ,IFN-γ ,TNF-α and IL-17 were detected by RT-PCR ;the protein expression level of JAK1 ,JAK2 ,STAT1 and STAT3 were evaluated by Western blot .(4)The changes of KCs expression type in each group were detected by flow cytometry (FCM ) and the laser confocal .(5)T cells derived from rat spleen cells were co-cultured within the 4 groups of KCs mentioned above ;T cells proliferation was measured by Brdu labeling assay .(6)T cells apoptosis was determined by Annexin V /PI FCM analysis .(7)The density of IL-6 ,IFN-γ ,TNF-α ,IL-17 and IL-10 in the su-pernatant of co culture was assessed by ELISA .Results (1)The mRNA and protein level of XBP1 were measured by RT-PCR and western blot ,those in XBP1-shRNA group were significantly reduced compared with those in the other three groups ,while in AdV-XBP1 groups ,results demonstrated entirely the opposite tendency (P< 0 .05) .(2)The expression of marker molecules on the sur-face of KCs such as M HC Ⅱ ,CD86 and CD40 in XBP1-shRNA group were significantly lower (P< 0 .05) ,but CD204 and CD206 expression were much higher compared with the other three (P< 0 .05) .However the expression tendency of these surface markers were shown the opposite results in AdV-XBP1 group (P < 0 .05) .(3)Western blot revealed the XBP1-shRNA could statistically suppress the protein levels and phosphorylation of JAK 1 ,JAK2 ,STAT1 and STAT3 ,which involved in the pro inflammatory cyto-kines regulation and KCs polarization (P< 0 .05) .But in AdV-XBP1 group ,these protein and its phosphorylation were markedly promoted (P< 0 .05) .ELISA results collaborated with Western blot .(4)3 d after co cultured with KCs transfected with XBP1-shR-NA ,the levels of T lymphocyte proliferation and pro inflammatory cytokines secretion were significantly reduced ,but the levels of T lymphocyte apoptosis and anti inflammatory cytokines secretion were remarkably enhanced (P< 0 .05) .Conclusion Blockage of IRE1-XBP1 activation could alter the phenotype of active KCs to M 2 like type and attenuated the capacity of antigen present of KCs ,while up regulated the expression of IRE1-XBP1 pathway could change the phenotype of KCs to M 1 type plus the promotion of antigen present capacity .
