Purpose:To observe the response and tolerance to the regimen of etoposide,folinic acid and fluorouracil (ELF) in advanced gastric cancer. Methods:Thirty two patients with advanced gastric cancer received chemotherapy of ELF regimen(VP 16 100 mg iv d 1—3 ,CF 100—300 mg iv d 1—3,5 FU 750 1 000 mg iv d 1—3 Results:The overall response rate was 37.5% (12/32) and complete response rate was 3.1% (1/31), the partial response rate was 33.4% (11/32). The main toxicity was myelosuppression and alopecia. Leukopenia was observed in 81.6% of the patients, but grade 3 and 4 in only 12.5%. Anemia and throbopenia was observed in 21.8% and 35.1% of the patients respectively, alopecia in 100%. Other side effects were uncommon. Conclusions:This study shows that the regimen of ELF is effective and tolerable for treatment of advanced gastric cancer. [

ObjectiveTo investigate the disruption of blood-brain barrier (BBB) after brain trauma in rats using IgG immunohistochemical staining.MethodsAn impact-acceleration head injury model was established with rats. Histological changes of rats' brains were observed by HE staining and light and electron microscopes at 1 h, 6 h, 24 h and 7 d after injury, and BBB permeability was analyzed semi-quantitatively by IgG immunohistochemical staining at the same time points.ResultsThe spot bleeding and brain edema was present in the damage region after brain trauma and endothelial cell damage and astrocyte swelling could be found under electron microscope. The extravasations of IgG was detected in the injured hemisphere of rats at 1 h, and achieved the peak at 6 h, remained a high level up to 24 h, and decreased at 7th d.ConclusionThe disruption of BBB function occurs after brain trauma in rats, and detection of IgG extravasations tested by immunohistochemical staining is a simple and sensitive way to investigate BBB permeability.

Objective To assess the effects of zinc protoporphyrin (ZnPP), an inhibitor of the heme oxygenase (HO), on the colonic interstitial cells of Cajal (ICC) of diabetic rats with colonic slow transit. Methods Diabetes mellitus (DM) model was induced by intraperitoneal injection of streptozotocin (STZ) in Sprague-Dawley rats. Twenty four successfully established DM rats were selected, and 16 healthy rats were served as controls. Six weeks later, gastrointestional (GI) dysfunction was observed by charcoal propulsion experiment in 8 DM rats and 8 controls. The rest rats in DM group were divided into 2 groups: DM rats intraperitoneal injected with PBS (n=8) or with 10 μmol/kg of ZnPP (n = 8) every other day for 3 weeks. The rats in control group (n = 8) were intraperitoneally injected with PBS. The levels of HO and c-kit (the special receptor of ICC) expression were detected by Western blotting. The distribution of ICC was observed by immunohistochemistry and the area of c-kit positive cells was counted. Results The GI propulsion rate in DM rats interfered with PBS was significantly declined compared to that in the controls (63.0%± 1.2% vs 71.8%±2.0%, P<0.05). But it was improved in DM rats interfered with ZnPP (72.5± 2.6%, P<0.05), which showed no significant differentee with that in control group (P>0.05). The expression of HO-1 in close and distant colon of DM rats interfered with ZnPP was decreased (P< 0.05). The expression of HO-2 in close colon and the area of c-kit positive cells of DM rats interfered with PBS was reduced compared with that in controls (P<0.05), but both were improved in DM rats interfered with ZnPP (P<0. 05). Conclusion Administration of ZnPP might be able to protect ICC by its blockage of HO-1 in DM rats with gastrointestinal dysfunction.

This study was aimed to establish the classification method of Chinese herbal medicine based on feature parameters extracted from images of herbal transverse section, in order to explore the feasibility of automatic identi-fication method of herbal medicine. The extracted 26 parameters of 18 herbal medicine images by gray-level co-oc-currence matrix and grayscale gradient matrix were used as the basic data set. And the minimum covariance determi-nant (MCD) was used to delete the outliers. A total of 18 identification models were established using the native Bayes method and BP neural network methods. The results showed that the average correct rates of models were 90%. It was concluded the feasibility of using these models in the establishment of the automatic identification method of herbal medicines. It provided new technologies for the quantitative, scientific and objective identification of Chinese herbal medicine.

Objective To investigate the correlation between ankle-brachial index (ABI) and early neurological deterioration (END) in patients with acute ischemic stroke. Methods Consecutive patients with acute ischemic stroke admitted to hospital within 7 d after onset from January 2014 to December 2014 were enroled. Bidirectional Doppler flow detector was used to detect ABI. END was defined as the increased National Institutes of Health Stroke Scale score ≥2 or the increased motor score ≥1. The demographic characteristics, vascular risk factors, laboratory parameters, and the incidence of END were identified and analyzed. Results A total of 210 patients with acute ischemic stroke were enroled, including 51 had END and 159 did not have END. Univariate analysis showed that the proportion of patient with ABI ≤0. 9 of the END group was significantly higher than that of the non-END group (43. 1% vs. 22. 0% ; χ2 = 8. 714, P =0. 003). Multivariable logistic regression analysis showed that ABI ≤0. 9 (odds ratio 2. 688, 95% confidence interval 1. 265 - 5. 052; P = 0. 009) was independently associated with END in patients with ischemic stroke after adjusting for the confounding factors, such as age, sex, baseline systolic blood pressure, and ischemic heart disease. Conclusion The low ABI was associated with the occurrence of END in patients with acute ischemic stroke.

Objective To evaluate and eliminate the potential bias between data obtained from dry and liquid biochemical assays,making data obtained by different assays matchable.Methods Bias estimation was performed based on document EP9-A2.Simple data comparison and methodology validation were performed after the experiment methods were modified with the estimated correction factors and interception.All the collected data were analyzed by EXCEL2007 software.Results The predicted bias of 4 of the 10 compared items exceeded their corresponding acceptable bias.After being adjusted by the coefficient and interception obtained from linear regression analysis,the four bias was improved and was within the acceptable range.The results of simple data comparison further confirmed this comparability.Conclusion Based on EP9-A2,we have established a protocol to obtain a consistency of data from different biochemical analyzers,which makes it possible that the detection results of the same patient from different detection systems can be used directly.The protocol has been approved by the experts during the medicinal laboratory accreditation of ISO15189.
