Objective To explore the clinical efficacy of ALIMTA (pemetrexed disodium) plus cisplatin.Methods Patients with malignant mesothelioma were allocated to two treatment groups envelope:pemetrexed plus cisplatin (PEM-group) or cisplatin alone (DDP-group).Results A total of 64 patients were randomly assigned and evaluated.The number of patients in PEM- and DDP-group had a significant pathologic complete response were (56.25 ％ vs 21.88 ％,x2 =7.943,P ＜0.05).Progression-free survival was significantly higher in PEM-group (P ＜0.05),and 2-year survival rate was lower in DDP-group (P ＜0.05).Conclusion Pemetrexed elicit significant tumor response and delays disease progression compared with DDP alone in patients with advanced MPM.Improvement in OS is seen in this study.

The traditional distal pancreatosplenectomy (DPS) has been the standard surgical procedure for the treatment of resectable pancreatic carcinoma of body and tail.With the development of medical technology,however,the results including the rate of R0 resection,number of lymph nodes dissected and postoperative 5-year survival rate were not significantly improved after DPS.According to pancreatic anatomy and phylembryogenesis,combined with renewed tumor treatment concept,the radical antegrade modular pancreatosplenectomy (RAMPS) was put forward after continuous exploration of pancreatic surgeons to improve prognosis of patients with pancreatic carcinoma of body and tail.Compared with DPS,RAMPS has advantages of R0 resection rate and regional lymphadenectomy and might become the standard surgical procedure.

As long non-coding RNA (LncRNA) research boom,Maternally Expressed Gene 3(MEG3) as LncRNA family is also a widespread concern.MEG3 not been studied in benign disease,and malignant disease more and more in-depth research.MEG3 because of the uniqueness of the tumor suppressor much attention in cancer research,but its specific mechanism of action of tumor suppressor and associated pathways have not been yet entirely clear,remains to be further research and clarify.This article will be now anticancer activity MEG3 and related Pathway summarized.

Aim The effect and mechanism of human placental extract(HPE) on the lipoprotein-cholesterol metabolism, peroxidation and the function of platelet aggregation in hyperlipaemia rats were abserved.Methods Wistar rat with hyperlipaemia models were given each HPE 0.4 ml (100 g)-1?d-1 through lavage for 12 days.The serum levels of TG,TC,LDL-C,HDL-C and HDL2-C in its subgroup were measured.The activies of LPO and SOD in both blood and liver tissue were determined .The effect of HPE on lipidosis of liver were abserved by fat dyeing.The levels of 6-keto-PGF1?,TXB2 in plasma and maximum platelet aggregation rate were measured by ELASA. Result The levels of HDL-C and HDL2-C were increased (P

AIM: To discuss the establishment of immediate diabetic keratopathy animal model of C57BL/6 mouse induced by ahigh-fat and high-glucose diet.
METHODS: Diabetes mellitus was induced by a high-fat and high-glucose diet in C57BL/6 mouse. 1% rose bengal was stained on the cornea to examine the integrality of the corneal epithelium at 2 ~ 12mo after completion of the model. Corneal epithelial wound healing was observed using a vivo epithelial debridement model which was dyed by sodium fluorescein. Corneal morphology histology was examined by pathological methods.
RESULTS: The high-fat and high-glucose diet C57BL/6 mouse in 2mo had showed general symptoms of diabetes: polydipsia, polyphagia, polyuria, weight loss etc. The model had a steady-state high glucose (≥18mmol/L), also the weight was lower compared with normal control mouse. 1% rose bengal corneal staining had dot coloring at 2mo after completion of the model, the stained area and extent were gradually increased with the extension of the duration of diabetes, almost all the cornea was stained at 12mo after completion of the
model. With the passage of time into a mold, the cornea epithelial healing time become longer: 2mo was about 40h;3mo was about 120h; 4, 6, 12mo was about 144h;the coloboma were gradually increased at 12mo after completion of the model, then the area was reduced gradually until complete healing, the time was 96~120h, showed repeating phenomenon.
CONCLUSION: The mouse were induced by high-fat and high-glucose diet can be used as animal models of diabetic keratopathy: the damage of epithelium for corneal and delay healing on epithelium and other symptoms.

Objective To analyze the outcomes and postoperative complications of renal transplant recipients of ethnic minorities and Han population in China, and investigate the differences between them. Methods Clinical data from 89 minority patients and 100 Han patients who had received renal transplant of Hans' donators in Organ Transplantation Center of PLA from 1990 to 2012 were retrospectively analyzed. The general data before transplantation, and rate of short-term survival of the graft, incidence of delayed graft function (DGF), acute rejection, and pulmonary infection after transplantation were analyzed and compared. Results No statistical difference was found in the preoperative personal profile between the recipients of minorities and Han nationality. In the recipients of minorities and Han nationality, the 1-year graft survival rate was 89.9% and 92%, the respective incidence of DGF was 28.1% and 27.0%, and the respective incidence of acute rejection was 22.5% and 19.0%, and there was no significant difference between them (P>0.05). The incidence of pulmonary infection was higher in minority recipients (30.3%) than in Han recipients (10.0%, P<0.01), but no significant difference was found between Tibetan, Hui, Manchu and Mongolian recipients in 1-year graft survival rate, incidence of DGF, acute rejection and pulmonary infection (P>0.05). Conclusion The short-term clinical outcome of renal transplant recipients seems to be similar in different Chinese ethnic groups, but the incidence of pulmonary infection is higher in minority recipients, so it is important to strengthen monitoring in early postoperative period.

Objective: To investigate the induetion of apoptosis in human renal tubular epithelial HK-2 cells by emodin and whether endoplasmic reticulum (ER) stress is involved in its mechanism. Methods: HK-2 cells were cultured and treated with various concentration of emodin at different time points. The cell viability was determined by MTT assay. The gene expression of glucose-regulated protein 78 (GRP78), CCAAT/enhancer-binding protein-homologous protein (CHOP), activating transcription factor 3 (ATF3), and X-box binding protein 1 splicing (XBP1s) was evaluated by quantitative real-time PCR. The protein expression of caspase-3, GRP78, CHOP, and eukaryotic initiation factor 2 alpha (eIF2α) was detected by Western blotting. Results: The viability of HK-2 cells was decreased by emodin in a dose-dependent manner, and the apoptosis of the cells was associated with caspase-3 shear activation. The treatment with emodin in HK-2 cells caused the increase in eIF2α phosphorylation, XBP1 mRNA splicing, the gene expression of GRP78, CHOP, and ATF3, and the protein expression of GRP78 and CHOP. The pretreatment with 4-phenylbutyric acid and salubrinal significantly increased the viability of HK-2 cells, indicating the role of ER stress in emodin-induced apoptosis. Conclusion: Emodin induces the apoptosis in HK-2 cells and ER stress is involved in emodin-induced apoptosis.

The cyclic voltammetric behaviors of sodium selenite on the gold electrode modified by L-cysteine self-assembled monolayer (L-Syc,Au/SAMs) has been investigated in 0.05 mol/L H_2SO_4 solutions with sodium selenite. Sensitive anodic stripping current of selenium (Se) with the peak potential at 0.99 V (vs. SCE) has been observed. In comparison with the electrochemical properties of sodium selenite on the modified electrode with those on the naked gold electrode, it was found that selenite was reduced to selenium by the redox interaction with sulfur on the monolayer and the monolayer catalytically oxidizes Se as the electrode was positively scanned. According to the electrochemical properties of sodium selenite both on the naked and modified gold electrode, the Se deposition mechanism and catalytic mechanism as well as bionic membrane model were proposed for the bio-utilization of selenite through nano scale selenium.
