The mechanisms underlying early neurological deterioration (END) after ischemic stroke are not clear.There are no reliable predictive factors and effective preventive measures for END.The glutamatemediated excitotoxicity plays a very important role in the cascade reaction of ischemic events.High level of glutamate in plasma is one of the important predictors for END.Studies have shown that the polymorphism in the promoter of the excitatory amino acid transporter-2 gene is a potential cause for individual susceptibility to END.Some therapeutic strategies of interrupting the glutamatergic pathways may be as the strategies of intervention END.

Postoperative atrial fibrillation (POAF) is the most common complication after cardiac surgery, which leads to hemodynamics disorder, prolongs hospitalization and increases mortality. The underlying mechanisms behind POAF are associated with cardiomyocyte injury, sympathetic activation and inflammation. The prediction of POAF is based on correlated index from pre-, intra-and post-surgery. POAF can be treated by rhythm and heart rate control as well as and antithrombotic therapy.

The blood-brain barrier (BBB) exerts its central nervous system (CNS) protective function as it hinders the delivery of diagnostic and therapeutic agents to the brain. With the development of nanotechnology during the last thirty years, the nanocarriers for delivering drugs make it possible to transport drugs across the BBB. The brain-targeted drug delivery system usually consists of two parts: nanocarriers and brain-targeted strategies. In this review, several kinds of nanocarriers are introduced for brain-targeted drug delivery. We focus on several possible strategies for brain-targeting and comment on their advantages and disadvantages in application.

Objective To explore the efficacy of ligustrazine combined with chemotherapy in patients with relapsed or refractory NHL and the relationships with P-gp expression. Methods 60 Patients were randomized into reversal agent group (ligustrazine + chemotherapy) and control group (chemotherapy) and the outcome was analysed. P- gp expression was analysed by flow cytometry. Subgroup analysis was conducted a ccording to P-gp expression. Results 56 patients could be evaluated. Progression -free survival (PFS) showed no statistical diference in two groups ( P = 0.065 1 ) ; reversal agent group had a higher overall response rate (ORR) than control group(P=0. 048).Subgroup analysis showed 41 patients had P-gp( +). The complete remission rate and complete remission uncertain rate of patients with P-gp( + ) in reversal agent group and control group were 33. 33% and 8. 70% , respectively, reversal agent group had a significant advantage ( P = 0. 048). Patients with P-gp( + ) in reversal agent group had a higher ORR than control group (61. 11% vs 26. 09% ,P =0.024). Kaplan-Meier survival curve and Log-rank test showed patients with P-gp( + ) in reversal agent group had longer PFS than control group (P =0.046 4). Blood pressure in a small number of patients received ligustrazine therapy decreased,and mitigated after reducing the dose. Conclusion Ligustrazine combined with chemotherapy can elevate response rate,prolong PFS with manageable toxicity and correlate to P-gp expression in relapsed or refractory NHL

Objective To investigate the value of procalcitonin in guiding the antibiotic use in acute exacerbation of chronic ob-structive pulmonary disease(AECOPD) .Methods A total of 184 patients with AECOPD in our hospital from March 2014 to Sep-tember 2015 were selected and divide into two groups by the random number table method .Ninety-two cases in the control group received the antibiotic therapy according to clinical experience .Ninety-two cases in the observation group was implemented the anti-biotic therapy according to serum procalcitonin level .Results Compared with before treatment ,the procalcitonin level after treat-ment in the observation group was decreased significantly (P<0 .05) .The procalcitonin level after treatment ,occurrence rate of a-cute exacerbation within six months and re-hospitalization rate within six months in the observation group were lower than those in the control group(P<0 .05) .The antibiotic use time ,antibiotic expenses ,hospitalization time and hospitalization cost in the obser-vation group were less than those in the control group(P<0 .05) .The total effective rate and hospitalization mortality rate had no statistical difference between the two groups (P>0 .05) .Conclusion Serum procalcitonin is significantly increased in the patients with AECOPD .Procalcitonin can be used for the optimized use of antibiotics .

Objective: To explore the mediation of stress between perfectionism and life satisfaction.Methods: 317 college students were surveyed with questionnaires.The data were analyzed by hierarchical regression.Results: ①Regarding general perfectionism,both male and female students' stress fully mediated negative perfectionism and life satisfaction but did not mediate positive perfectionism and life satisfaction;②Regarding domain-specific perfectionism,male students' appearance stress fully mediated related perfectionism and satisfaction,but for female students its mediation was partial.Both male and female students' personality stress fully mediated personality perfectionism and satisfaction.Mediation models involved academic,love,interpersonal relationship perfectionism and their related satisfaction were not found.Conclusion: The mediations of stress between perfectionism and life satisfaction are different in different life domains.

OBJECTIVE:To evaluate the hemostatic effect of Reptilase on bleeding after pneumonectomy.METHODS:324cases of lung cancer were randomly divided into2groups and the volume of postoperative thoracic drainage in Reptilase group and control group was measured at24h,48h and72h after operation.RESULTS:The drainage volume in Reptilase group was much lower than that in control group.CONCLUSION:Reptilase can reduce the volume of thoracic drainage after thoracic surgery.

Objective To explore the effect of chitosan on the prevention of postoperative peritoneal adhesion. Methods Forty-five Wistar rats were randomly assigned into group A(control group);group B and group C;2 ml of 1% lactic acid, 32% Dextran-70 or 2% Chitosan-lactic acid (CLA) was admitted on the region of serosal injury of intestine respectively during operation. The adhesive degree was observed and biopsy was taken on the 14th postoperative day. Results There were statistically significant differences among the degrees of adhesions between the three groups (P

Objective To investigate the role of HMGA2 expression and epithelial to mesenchymal cell transformation in the regulation of TGF -β1 in human gastric cancer cells .Methods Human gastric cancer cell SGC-7901 was treated by TGF-β1 at different time points(0,3,6,24,48,72 h).We observed the changes in cell morphology of SGC-7901 through the microscope;HMGA2 assay,E-cadherin,Vimentin protein expression wereperformedbyWesternblot;cellinvasioncapabilitywasanalyzedbytranswellchamberassay.Results (1) With the prolonged duration of action of TGF -β1,SGC-7901 changes in cell morphology ,cells gradually be-came longer and larger.(2)In the role of TGF-β1,gastric cancer cells SGC -7901 are varying degrees of HM-GA2 expression and E -cadherin、Vimentin.HMGA2 protein begun to express from 0h to 6hrs.and HMGA2 pro-tein became the strongest at 6hrs and decreased slightly from 24hrs.E-cad protein expression at 0h begun at 3hrs highest expression ,and the reduction started from 3hrs.Vimentin protein was the highest at 48hrs then gradu-ally decreased.Conclusion In the TGF-β1 induced the process of epithelial to mesenchymal cell transforma-tion in gastric cancer cells SGC -7901 ,HMGA2 protein play an important role .HMGA2 can be used as snail pro-moter,combined with Smads ,promotes the process of epithelial -mesenchymal transformation .HMGA2 may also be regulated by Wnt /β-Catenin signaling pathway on growth and apoptosis of tumor cells .
