Objective To investigate the effects of oxiracetam combined with Shuxuetong injection on hemorheology and serum Hcy levels in patients with cerebral infarction. Methods 60 patients with cerebral infarction were randomly divided into 2 groups, 30 cases in the observation group and were treated with oxiracetam combined with Shuxuetong injection. 30 cases in the control group were treated with Shuxuetong injection. The hemorheology and serum Hcy levels in the two groups were compared. Results After treatment, the hemorheological indexes and serum Hcy levels in the observation group were lower than those in the control group (P<0.05). The treatment effect of the observation group was better than that of the control group (P<0.05). The scores of neurological deficits in the observation group were significantly better than those in the control group (P<0.05). The number of complications in the observation group was 2 cases, the incidence of complications was 6.7%, which were significantly lower than 9(30.0%) in the control group, the differences between the two groups was statistically significant (P<0.05). Conclusion The application of oxiracetam combined with Shuxuetong injection in patients with cerebral infarction can effectively improve the hemorheology and reduce the serum Hcy level.

Objective To analyze clopidogrel combined with aspirin therapy of acute cerebral infarction the safety and efficacy of micro brain hemorrhage patients.Methods Select from May 2015 and May 2015 months in the hospital for diagnosis and treatment of 76 cases of acute cerebral infarction combined micro cerebral hemorrhage patient study,observation group in the conventional treatment at the same time giving oral aspirin and clopidogrel,the control group in the conventional treatment at the same time,only to give oral aspirin.To observe the nerve function defect National institutes of Health stroke scale score(National Institute of Health stroke scale,NIHSS)and daily life activities ability pap index,determination of patients' blood plasma viscosity,whole blood low shear viscosity,AA induction and the platelet maximum aggregation rate induced by ADP(MARAA,MARADP),observation records during the treatment patients with adverse reactions,were analyzed.Results Compared with before treatment,the observation group and control group after treatment for 2 weeks,NIHSS score,score and blood related indexes were significantly improved,statistically significant difference(P< 0.05).Compared with control group,the observation group after treatment the NIHSS score,pap score and blood related indexes were significantly improved,total effective rate increased significantly,the differences were statistically significant(P< 0.05).Two groups of adverse drug reactions occurred situation is no statistical difference.Conclusion Clopidogrel in combination with aspirin can effective treatment in patients with acute cerebral infarction combined micro brain hemorrhage,and security.

BACKGROUNDNeoadjuvant chemotherapy (NACT) plays an important role in systemic chemotherapy for non-small cell lung cancer (NSCLC). P-glycoprotein (P-gp), lung resistance related protein (LRP), multidrug resistance-associated protein (MRP) and glutathione S-transferase (GST-π) may be associated to drug resisitance to chemotherapy in NSCLC. The aim of this study is to investigate the expressions of P-gp, LRP, MRP and GST-π in samples from NSCLC patients before and after treatment with NACT, and their quantitative changes, so that to evaluate the influence of NACT on drug resistance to chemotherapy of NSCLC.

METHODSTotal 92 specimens from 72 cases of NSCLC, including 52 samples of surgery excision from non-NACT-treated patients and 20 paired samples before and after NACT from the same patient, were studied. The expression of P-gp, LRP, MRP and GST-π was detected with tissue chip technique and immunohistochemistry. The quantitative analysis was carried out by computer image analysis system..

RESULTSIn the samples before NACT, the positive rate of P-gp, LRP, MRP, GST-π expression was 66.67% (48/72), 72.22% (52/72), 81.94% (59/72), 83.33% (60/72), respectively. The expressive intensity of P-gp, LRP and GST-π was significantly stronger in adenocarcinoma than that in squamous cell carcinoma (P < 0.05, P < 0.001, P < 0.001, respectively); there was no significant difference in the expression of MRP between adenocarcinoma and squamous cell carcinoma (P > 0.05). In samples after treatment with NACT, the expression of P-gp, GST-π demonstrated by average optical density (AOD) and integral optical density (IOD) were significantly higher (P < 0.05, P < 0.001 respectively) than that in biopsied samples taken before NACT; The change in expression of P-gp, GST-π was also showed difference by different histopathological types, differentiations, ages, sizes, clinical stages as well as lymph node metastasis or not (P < 0.05 or P < 0.001). There was no significant difference between samples taken before and after NACT (P > 0.05) in the expression of LRP and MRP demonstrated by both of AOD and IOD.

CONCLUSIONSThe results suggest that drug resistance in adenocarcinoma is primarily stronger than that in squamous cell carcinoma. NACT may enhance acquired drug resistance of NSCLC through inducing the expression of drug resistance protein. The results indicate that acquired drug resistance must be considered with the application of NACT to NSCLC patient in clinic, especially to patient in stage I and II. Since NACT may lead to the enhancement of acquired drug resistance in stage I and II, this may dwindle the therapeutic effect of chemotherapy after surgery. Comparative examination of drug resistance proteins before and after NACT, combining with comprehensive consideration of chemical regimens of NACT, should be recommended during chemotherapy of NSCLC for both before and after surgery.

Objective To investigate the effects of high intensity electric field on cell growth,apoptosis and microstructure of human pancreatic cancer cell line PANC-1.Methods The PANC-1 cells in the logarithmic growth period were selected,and cells in the high voltage electrical treatment group were treated with high voltage electric field 250,500,750,1000 V/cm,respectively.The effects of different high voltage electric fields on cell growth and microstructure of PANC-1 cells were determined by cell viability,cell death staining,apoptosis detection,transmission electron microscopy and scanning electron microscopy.Results Compared with control group,the high voltage electric pulse significantly inhibited the growth of PANC-1 cells in the field dependent manner.Moreover,when the field was more than 500 V/cm,the cell viability was significantly decreased (P＜0.05).High voltage electric pulse could induce cell apoptosis.When the field was higher than 750 V/cm,serious necrosis was noticed.In the 1000 V/cm group,the integrity of cell membrane and the structure of organelles was seriously damaged.Conclusion High voltage electric pulse could significantly inhibit the growth of PANC-1 cells and would be a promising method in cancer treatment.

A biliary contrast agents pushing device, including a syringe pushing system and a remote controller is introduced. The syringe pushing system comprises an injector card slot, a support platform and an injection bolus fader. A 20 mL syringe can be fitted on the syringe pushing system and kept with the ground about 30 degree. This system can perform air bubble pumping back and contrast agents bolus injection as well as speed adjustment. Remote controller is an infrared remote control which can start and stop the syringe pushing system. With this device, the remote controlled cholangiography technology can be achieved, which can not only protect doctors from X-ray radiation but also improve the traditional T-tube cholangiography and the contrast effect, reduce postoperative complications in patients as well. The application of this device will improve the current diagnosis and treatment system, the device will benefit the majority of doctors and patients.

Irreversible electroporation (IRE) is an emerging tissue ablation technique. Compared with thermal ablation technique such as radiofrequency, IRE can achieve focal ablation in a shorter time without heat sink effect while sparing the tissue scaffold. IRE has been demonstrated to be a feasible therapeutic modality for the liver, pancreatic, and prostatic cancer. In recent years, several studies regarding of catheter-directed IRE for digestive tract, bronchus, urinary tract, and myocardium have been performed, which preliminarily demonstrated the safety and efficacy of IRE for tissue ablation under endoscopic or interventional technique. This study summarized the research progress of catheter-directed IRE for tissue ablation. The critical technique and future direction of catheter-based IRE are prosp.
