Objective:To determine phenolphthalein illegally added into diet health products by Raman spectroscopy. Methods:Raman spectroscopy was used to determine phenolphthalein added into diet health products. The diet health products were extracted by suitable solvents, and then the extracting solution was measured by Raman spectroscopy. Results: A calibration curve was built and the analysis was performed on the samples with phenolphthalein at different concentrations. The results were accordance with the real added amount. Conclusion:With simple sample preprocessing method, Raman spectroscopy can be used in the fast detection of phe-nolphthalein illegally added into diet health products. The method is fast and simple with low cost, and can provide both qualitative and quantitative results. The detection limit is 1% for phenolphthalein in diet health products.

BACKGROUND:It is reported that gelatin sponge particles and chitosan/α, β-glycerophosphate gel microspheres have high application prospects in the treatment of hemoptysis of pulmonary tuberculosis.METHODS: Forty SPF Kunming mice were selected to make animal models of pulmonary tuberculosis hemoptysis using aerosolized inhalation device and randomly divided into two groups undergoing embolization for hemostasis using gelatin sponge particles and chitosan/α, β-glycerophosphate gel microspheres, respectively. Body mass changes, hemostasis time, effective rate of hemostasis, related indexes of myocardium and pathological changes of pulmonary tuberculosis were observed at 15 and 30 days after treatment.RESULTS AND CONCLUSION:(1) Mice in the chitosan/α, β-glycerophosphate gel microspheres group had higher body mass than those in the gelatin sponge group at 15 days after treatment (P < 0.05). (2) Compared with the gelatin sponge group, the hemostatic efficiency was higher and the time of hemostasis was shorter in the chitosan/α, β-glycerophosphate gel microspheres group (P< 0.05). (3) There were no significant differences in the levels of BNP precursor, creatine kinase isoenzyme and creatine kinase between the two groups (P > 0.05). (4) The lymphocyte infiltration and necrotic lesions were found around the microspheres, necrotic lesions were found, and there were a lot of active cells on the microspheres. There were a few lymphocytes in the gelatin sponge group. These results show that that the chitosan/α, β-glycerophosphate gel microspheres have better hemostatic effects in comparison with gelatin sponge particles in a mouse model of pulmonary tuberculosis.

OBJECTIVE: To investigate the features of adverse drug reaction(ADR) in our hospital and evaluate the quality of ADR report in order to promote rational clinical drug use and find out the existing problems in the report. METHODS: Microsoft Excel was designed to analyze statistically the sex and age of the patients,category of the used drugs and the clinical manifestations of ADR in 311 cases of ADR report collected between 2002 and 2005.RESULTS: The occurrence of ADR induced by antibacterials ranked the first.ADR affecting skin and its appendages counted for 50% of the total.The numbers of ADR reports were found to be less than expected.CONCLUSIONS: Professional staff training should be strengthened,the use of antibacterials should be rationalized to lessen and avoid the occurrence of ADR.

A bacterium(designated as LW-3), capable of degrading Chlorimuron-ethyl, was isolated from the long-term contaminated soil by Chlorimuron-ethyl. Based on physiological and biochemical analyses and sequences comparison of 16S rDNA, strain LW-3 was identified as Pseudomonas sp. LW-3 could use Chlorimuron-ethyl as sole nitrogen source for growth. The optimum pH and temperature for degradation of Chlorimuron-ethyl were pH 6.5~7.2 and 30?C~35?C, at same temperature the pH change to the Chlorimuron -ethyl degrading influence is large. When the pH and temperature were pH 6.5 and 32?C, 50 mg/L Chlori- muron-ethyl could be degraded to 70%~80% level within 7 days.

Objective To explore the psychological stressors of pregnant women with chronic HBV infection.Methods Using phenomenological method of qualitative study,there were 9 pregnant women with chronic HBV infection participated in the study and their mental stress was investigated by deep interview.Results Five main psychological stressors of pregnant women with chronic HBV infection emerged:fear of children being infected; anxious about giving birth in the hospital for infectious diseases; having no idea of selecting the mode of delivery and feeding pattern; worrying about their own health; to feel nervous about playing the role of mothers.Conclusions Healthcare workers should make appropriate health guidance and psychological supports to alleviate the psychological distress combined with features of pregnant women with HBV infection.At the same time,it is necessary to make change of public misunderstanding of hepatitis B,so as to create a fair and friendly social atmosphere for all the hepatitis B patients.

Objective To explore the relationship between genetic variation in PAF-AH V279F and coronary heart disease among Han population in Beijing.Methods A case-control study was held which enrolled 124 patients with coronary heart disease and 103 normal subjects.The genotype of PAF-AH V279F was determined with allele-specific polymerase chain reaction(AS-PCR)method. Results The highest frequency of PAF-AH V279F genetic variation was VV genotype(92.2%),the next was VF genotype(5.8%)and the lowest was FF genotype(2.0%)among the studied Han population in Beijing.In the coronary heart disease group the frequency of 279 V→F carriers was significantly higher than in the control group(19.3% vs.7.8%,P＜0.05)and F allele frequency was also higher(12.1% vs.4.9%,P＜0.01).Among the coronary heart disease group,the V279F variation frequency and the F allele frequency were significantly higher in patients with myocardial infarction than in those without myocardial infarction(27.3% vs.13.0%,17.3% vs.8.0%,both P＜0.05).In multiple logistic regression analysis,the odds ratio(OR)of V279F genetic variation for coronary heart disease was 1.919(95% CI:1.448-2.544,P=0.033).Conclusions The PAF-AH V279F genetic variation may be a novel genetic marker for high risk of coronary heart disease.

Background and purpose:The occurrence and development of lung cancer are closely correlated with the immune function in the human body.The patients with malignant tumors have shown a disorder of immune function,especially in terms of loss of cellular immune function.The purpose of this study was to investigate the possible auxiliary effect of sipulin in the treatment of advanced non-small-cell lung cancer(NSCLC).methods: Ninety-three patients were randomly divided into two groups:sipulin group:sipulin plus docetaxel+cisplatin;control group:only administered docetaxel+cisplatin.The leukocyte,haemoglobin and platelet,toxicity of digestive tract,body weight,Karnofsky status and efficacy of those patients were evaluated before and after therapy,respectively.Results: Overall response rates were 46.67% and 30.23%(P=0.023)in sipulin group and control group,respectively.The median survival time was 10.1months versus 8.3 months(P=0.035)in sipulin group and control group,respectively.The 1-year survival rate for sipulin group and control group was 52.9% versus 39.4%(P=0.038),respectively.The clinical efficacy and the frequence of leukocyte reduction were better in sipulin group than in control group,the quality of life and clinical symptom of the patients in sipulin group were improved more significantly than those in control group (P

A method was proposed for the separation and determination of paraffin waxes in food by HPLC-evaporative light scattering detection (ELSD). A normal-phase column was used to separate nonparaffinic and paraffinic materials without resolving the latter into individual components. The t-test method was adopted for the evaluation of mean difference between response factors of n-alkanes in paraffin waxes on ELSD detector. No mean difference was obtained between response factors, which can be used for quantitative determination of paraffin waxes in food. The determination results obtained by HPLC-ELSD were compared with those by GC-MS. The linear range for the determination of paraffin waxes was in the range from 10 to 500 mg/L with a correlation coefficient of 0.9988, and the limit of detection was 1.0 mg/L. With the spiking level of 10, 50 and 100 mg/kg, the recovery ranged from 84.6% to 105.4% and the relative standard deviation ranging from 5.4% to 7.2%. The proposed method is simple, fast and sensitive.
