Objective To study the effects and significance of thrombexane -B_2(TXB_2)and six-ketone-prostaglandin(6-k-PG)F1 α levels in the primary type of hyper-acute cerebral infarction with different sensitivities to aspirin.Methods Sixty-three patients with primary type of hyper-acute cerebral infarction were divided into three groups based on their sensitivities to aspirin:aspirin resistance(AR)group,aspirin semiresistance(ASR)group,aspirin sensitivity(AS)group.TXB_2 and 6-k-PGF1α levels were measured,compared and analyzed in the three groups before and two weeks after taking aspirin(100 mg/d).Results The total effective rate in AS group[87.0%(20/23)]was significantly higher than that in ASR group[55.0%(11/20)]and AR group[30.0%(6/20)](P<0.05).There was no significant difference of TXB_2 and 6-k-PGF1 α among the three groups before taking aspirin.After taking aspirin for two weeks,TXB_2 leveh in all the three groups were lower than those before making aspirin(P<0.01),6-k-PGF1α levels in all the three groups were higher than those before taking aspirin(P<0.01).Conclusions Aspirin can decrease the TXB_2 concentration and increase the 6-k-PGF1α concentration of the primary hyper-acute cerebral infarction. It may be reduce the risks of re-infarction after the primary acute infarction. Monitoring the concentration of TXB_2 and 6-k-PGF1α can be helpful to evaluate rehabilitation prognosis.

Objective To study changes of urinary protein in premature infants after asphyxia in order to explore influence of asphyxia on the renal function. Methods Microalbumin(mAlb),retinal-bindingprotein (RBP) ,N-acety-?-D-aminoglucosidase in urine and serum urea nitrogen(BUN),creatinine(Cr) were performed in 56 normal premature infants and 49 asphyxia ones with immunoturbidimetric method, ELISA method, rate method , enzymic method and picric acid method when they were 1,4,7 day age after born. Results (1)With ages increasing urinary mAlb took on decreasing trend in the same gestation age but there was no different while with the gestation age increasing in the same ages urinauy mAlb was decreased significantly (P

Shenfukang is an effective formula for glomerulonephritis applied in the first affiliated hospital of Guangzhou University of TCM. It is composed of Radix Folium seu Flos Tripterygii wilfordii, Radix Astragali seu Hedysari, Radix Notoginseng, Herba Leonuri, etc.. Glomerulonephritis rat model was induced by cationized bovine serum albumin (C-BSA) according to Border's method and was used to observe the pharmacological action of Shenfukang. The results showed that Shenfukang can eliminate urine protein, increase the levels of serum protein, albumin (A), globulin (G) and A/G ratio, and decrease the contents of serum cholesterol, creatinine and urea nitrogen. It can also counteract the increase of plasma TXB 2 and the decrease of plasma 6-keto-PGF 1? . LD 50 of Shenfukang for mice is 174.34?36.74?g/kg which is much larger than that of Tripterygium wilfordii (29.73?6.46?g/kg for female mice and 101.74?10.93?g/kg for male mice). It is indicated that Shenfukang exerts a protective effect on renal function and reduces toxicity of Tripterygium wilfordii.

Objective To investigate the symptoms and affecting factors of food intolerance among 903 adults.Methods Food special antibody(IgG)in human serum were examined by ELISA.Food Intolerance Health Assessment Questionnaire was used to assess positive rate of food intolerance and food intake habits.Chi-square test and Mann-Whitney test were used for data analysis.Results The ratio of food intolerance was 0.33% to 28.13%.Intolerant foods include crab(28.13%),yolk(27.02%),milk (13.07%),soybean(11.96%),shrimp,tomato,corn,beef,rice,chicken,mushroom,wheat,and pork.The symptoms of nervous system(55.89%),digestive system(45.69%)and respiratory system(15.64%)were commonly seen.Prevalence of food intolerance in mental labors was lower than manual labors.Conclusion The most common intolerant food includes crab,yolk and milk.The symptoms of food intolerance are different.Manual labors are more susceptible to food intolerance.

Background and purpose:Chemotherapy is an alternative treatment option, which could still get a therapeutic effect, when the EGFR-TKI treatment of non-small cell lung cancer failed. Studies have shown that RR, TYMS, ERCC1 and TUBB3 have respectively relationship with chemosensitivity of gemcitabine, pemetrexed, platinum-based drugs and microtubule-based chemotherapy drugs.The expression levels of these molecular markers can predict the sensitivity of these chemotherapy drugs. The patients with RRMI, TS, ERCC1 and TUBB3 higher expression have reduced chemosensitivity, and lower expression have increased sensitivity. The purpose of this study was to explore the sensitivity of tumor cell lines with acquired resistance to geiftinib caused byEGFR-T790M mutation to cisplatin, gemcitabine, pemetrexed, vinorelbine, paclitaxel and docetaxel.Methods:MTT assay was used to detect the IC50 values of cisplatin, gemcitabine, vinorelbine, paclitaxel and docetaxel, pemetrexed to PC9 and PC9/GR cells, and to explore the chemosensitivity of lung adenocarcinoma cells to these chemotherapy drugs; Luminex method was used respectively to detect the expression levels of ERCC1 mRNA, TUBB3 mRNA, TS mRNA, and RRM1 mRNA in PC9 and PC9/GR cells. Western blot was used to detect the protein expression levels of ERCC1, TUBB3, TS and RRM1 in PC9 and PC9/GR cells.Results: The IC50 values of cisplatin, gemcitabine and pemetrexed to PC9/GR cells were signiifcantly higher than those to PC9 cells (P<0.05), while the IC50 values of vinorelbine, paclitaxe and docetaxel to PC9/GR cells were signiifcantly decreased (P<0.05). Luminex method showed the expressions of ERCC1 mRNA, TS mRNA and RRM1 mRNA in PC9/GR cells were signiifcantly increased than those in PC9 cells (P<0.05), while the expression of TUBB3 mRNA was signiifcantly decreased (P<0.05). Western blot method showed the expressions of TUBB3, TS and RRM1 protein in PC9/GR cells were signiifcantly increased than those in PC9 cells (P<0.05), while TUBB3 protein expression in PC9/GR cells was signiifcantly decreased (P<0.05). Western blot method analysis result showed that the expressions of TUBB3, TS and RRM1 protein in PC9/GR cells were significantly increased than those in PC9 cells (P<0.05), while TUBB3 protein expression in PC9/GR cells was signiifcantly decreased (P<0.05). Conclusion:The chemosensitivity of lung adenocarcinoma with EGFR-T790M mutation is changed. It has decreased sensitivity to cisplatin, gemcitabine, pemetrexed and increased sensitivity to vinorelbine, paclitaxel and docetaxel. The reason of the change of chemosensitivity of geiftinib-resistant lung adenocarcinoma cell maybe related to the changes of ERCC1 mRNA, RRM1 mRNA and TS mRNA and their protein expressions.

0.05). Conclusions For patients with locally advanced non-small cell lung cancer, concurrent conformal radiotherapy and chemotherapy followed by consolidation chemotherapy can improve the progression-free survival, but have few effects on overall survival and toxicity. Multicenter clinical trial with more patients should be carried out to confirm the benefit from the additional consolidation chemotherapy.

[Objective] To observe the counteractive action of cyclovirobuxinum D (Cvb-D) for myocardial ischemia and to explore its possible mechanism. [Methods] Sixty SD rats were randomized into blank control group, Cvb-D groups in the dosage of 2.2, 1.1 and 0.55 mg? kg-1 ? d-1 respectively, isosorbide dinitrate group (25 mg? kg-1 ?d-1). The blank control group was treated with distilled water and the other groups were treated with the corresponding drugs by gavage according to the experimental design for 30 days. One hour after the last medication, pituitrin (1.5 U/kg) was injected into the caudal vein of the rats except the blank control to induce coronary artery spasticity myocardial ischemia. After that, electrocardiogram (ECG) was recorded, plasma superoxide dismutase (SOD) activity, malonyldialdehyde (MDA), lactate dehydrogenase (LDH) and phosphocreatine kinase ( CPK) levels were detected. [ Results ] The incidence of ischemic changes in ECG was decreased, plasma SOD activity increased and MDA, LDH and CPK levels lowered in Cvb-D groups as compared with those in the model group (P
