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: 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.

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

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.

Objective To compare the therapeutic effect between routine shunting and selective shunting in patients with moderate and severe carotid artery stenosis undergoing carotid endarterectomy (CEA). Methods One hundred and ninety-two patients with moderate and severe carotid artery stenosis undergoing CEA were selected, and the patients were divided into control group (routine shunting) and observation group (selective shunting) according to the random digits table method with 96 cases each. The intraoperative carotid artery occlusion time and incidences of stroke event 30 d after operation were recorded. Results In the observation group, the rate of carotid artery shunting was 35.4％ (34/96), among which the rate of carotid artery shunting in patients with contralateral severe carotid artery stenosis or occlusion was 8/13, the rate of carotid artery shunting in patients with unilateral carotid stenosis was 31.3％ (26/83), and there was statistical difference (χ2 = 13.006, P<0.01). There was no statistical difference in intraoperative carotid artery occlusion time between control group and observation group ( t=2.091, P>0.05). In the observation group, the intraoperative carotid artery occlusion time in patients with carotid artery shunting was significantly shorter than that in patients without carotid artery shunting:(4.36 ± 0.48) min vs. (10.15 ± 0.91) min, and there was statistical difference (t=7.884, P<0.05). There was no statistical difference in the incidence of stroke event 30 d after operation between control group and observation group (χ2 = 1.189, P>0.05). Conclusions The selective shunting during CEA can reduce the incidence of postoperative stroke event in patients with carotid artery stenosis, and especially it can give a good clinical effect in the patients with contralateral severe carotid artery stenosis or occlusion.
