The serum concentration of vitamin A (VA) and B-carotene were determined in 50 healthy pregnant women in the later trimesters and parturition, their newborns and 20 non-pregnant women. In the meantime the contents of placental tissues were determined too. The results showed; 1. The serum VA content(2.17 umol/L, 62ug/dl)of pregnant women in the later trimesters was higher than that of non-pregnant women (1.37umol/L, 39ug/dl), but it decreased immediately after delivery. 2. There was no significant def-ference of the serum B-carotene concentration between the pregnant women and non-pregnant women. 3. The cord blood VA and B-carotene contents were much lower than those of maternal blood. 4. The contents of B-caro-tene in placentas were 9.6 times as much as VA. 5. The efficiency of transport of B-carotene from maternal blood to placental tissue was higher than that of VA, and lower than that from placenta to cord blood.

Objective To evaluate the clinical effect of salmeterol xinafoate and fluticasone propionate powder for inhalation combined ipratropium bromide aerosol in patients with stable chronic obstructive pulmonary disease (COPD).Methods One hundred and twenty patients with stable COPD was randomly divided into control group and observation group with 60 patients each.The control group was received ipratropium bromide aerosol inhalation,and the observation group was given salmeterol xinafoate and fluticasone propionate powder for inhalation and ipratropium bromide aerosol for 6 months.BODE index,SGRQ scores,plasma cortisol and bone mineral density were compared between two groups before and after treatment.Results BODE index scores had no significant difference between two groups before treatment (P＞0.05).After treatment,BODE index scores,dyspnea scale,FEV1％,6MWD and BODE index total scores in observation group were superior to those in control group [ (1.9 ± 0.5) grades vs. (2.3 ± 0.5)grades,(58.5 ± 7.3)％ vs.(50.4 ± 6.2)％,(411.1 ± 56.8) m vs.(347.5 ± 60.4) m,(3.3 ± 1.0) scores vs.(3.8 ± 1.3 ) scores ],there were significant differences (P＜0.05 ).SGRQ scores had no significant difference between two groups before treatment (P＞0.05 ).After treatment and in SGRQ scores,respiration symptom,limitation of activity,disease influence scores in observation group were significantly lower than those in control group [ (20.7 ± 10.3 ) scores vs.(37.9 ± 14.4) scores,(20.7 ± 9.5 ) scores vs.(34.8 ± 13.0) scores,(16.3 ± 6.7) scores vs.(27.2 ± 11.8) scores,(17.5 ± 7.0) scores vs. (34.6 ± 12.3) scores],there were signiticant differences (P＜0.01 ).There were no significant difference of plasma cortisol and bone mineral density between two groups (P＞0.05).Conclusions Salmeterol xinafoate and fluticasone propionate powder for inhalation and ipratropium bromide aerosol in patients with stable COPD can greatly improve the lung function and life quality and with less adverse reaction.

Objective: To investigate the antimotion sickness effects of ginsenosides combined with dexamethasone in rats. Methods: Fifty SD rats were randomly divided into 5 groups: normal saline, scopolamine-treated, ginsenosides-treated, dexamethasone-treated and ginsenosides plus dexamethasone-treated groups. There were 10 rats in each group. The rats in each group were fed with corresponding ingredients respectively, and then the rats were exposed to abnormal acceleration for one hour. The motion sickness index, the level of kaolin consumption and the course and time of spontaneous activity were observed. Results: The motion sickness index and the level of kaolin consumption of acceleration-exposed rats in ginsenosides plus dexamethasone-treated group were significantly lower than those in normal saline group. And the course and time of spontaneous activity of acceleration-exposed rats in ginsenosides plus dexamethasone-treated group were significantly higher than those in normal saline group. The level of body weight increment of acceleration-exposed rats in ginsenosides plus dexamethasone-treated group was significantly higher than that in dexamethasone-treated group. Conclusion: Ginsenosides combined with dexamethasone can significantly increase tolerance to acceleration of rats, and the drug combination can decrease side effects of methylprednisolone, such as body weight loss.

Objective To assess the application of Xpert MTB/RIF assay in rapid diagnosis of tuberculous lymphadenitis.Methods Lymph node samples were collected from 1 02 clinically diagnosed patients with lymph node tuberculosis and 65 patients with other lymph node diseases from Zhejiang Provincial Hospital of Traditional Chinese and Western Medicine during January 201 4 and February 201 5. Xpert MTB/RIF,pathological examination and mycobacterium tuberculosis culture were conducted in all specimens of two groups.Taking clinical comprehensive diagnosis as the gold standard,the diagnostic sensitivity,specificity,positive predictive value,negative predictive value and diagnosis efficacy of three detection methods were assessed.The sensitivity of Xpert MTB/RIF in determining rifampicin resistance was analyzed using drug susceptibility testing as gold standard.Results The mean detection time of Xpert MTB/RIF was (2.2 ±0.2)h.Among 1 02 patients,Xpert MTB/RIF achieved higher sensitivity (96.1 %, 98 /1 02 ) than pathological examination (76.5%,78 /1 02 ) and mycobacterium tuberculosis culture (33.3%,34 /1 02)(χ2 =1 6.558 and 87.91 9,both P <0.01 ).Among 65 patients with other lymph node diseases,the specificity of all three detection methods was 1 00%.The receiver-operating-characteristic curve analysis demonstrated that diagnostic performance of Xpert MTB/RIF was better than that of other two methods.In 8 patients resistant to rifampicin confirmed by drug susceptibility testing,Xpert MTB/RIF detected 6 resistant-resistant patients.Conclusion Xpert MTB/RIF shows higher sensitivity and specificity in diagnosis of lymph node tuberculosis with the advantages of easy and rapid performance.

Objective To analyze the basics and influencing factors for the medical expenditure of poor patients of tumor and end-stage renal diseases in Hubei province,and put forward policy recommendations for the critical illness insurance and health poverty alleviation.Methods 535 patients with tumor and end-stage renal diseases in Wuhan,Xiangyan and Shiyan in Hubei province were selected for a questionnaire survey,with 415 of the questionnaires subject to data analysis.Single factor variance analysis and multiple linear regression were used to analyze the influencing factors for their medical expenditure.Results 83.9% of the patients held their medical costs as too high;84.6% of them complaining significant drop of their annual family income due to their diseases; disposable household income of urban patients higher than their rural counterparts both before and after their disease; types of medical insurance and diseases are significant influencing factors for medical expenditure.Conclusions Poverty rate is high among patients of such patients.To reduce their financial burden,the government is recommended to cover more major diseases,enhance support for those of critical illness and improve the medical assistance system.

Results In the cells of X\|zone which located in the interface between adrenal crotex and medulla, there were expressions of type Ⅰ and Ⅲ 17? HSD.Conclusion\ The X\|zone cells of adrenal gland in immature mouse could synthesize androgen, enhanced the male sexual differentiation together with the androgen synthesized from the testis.\;[

Objective To study the regulation role on molecular level of hCG on P450scc,P450c17 and 3?HSD in adult mouse Leydig cells. Methods Leydig cells of adult mice were cultured in vitro for 1 and 8 hours with or without hCG,then P450scc,P450c17 and I,VI total 3?HSD mRNA levels were measured respectively by the semi quantitative RT PCR as well as Scal restriction endonuclease incised methods.Meanwhile,the testosterone contents were measured in two groups. Results 1.In stimulated group Leydig cells cultured for 1 and 8 hours with hCG,the testosterone contents were higher significantly than those in control groups(1 hour P 0.05),but the ratio of type VI/I 3?HSD mRNA gradually increased. Conclusion hCG can stimulate the transcription of P450scc,P450c17 and type VI 3?HSD in adult mouse Leydig cells.
