Objective: To investigate the effect of Astragalus on peritoneal macrophages function in stable continuous ambulatory peritoneal dialysis(CAPD) patients. Methods: 28 stable CAPD patients were included in this study.All the patients were treated with peritoneal dialysis fluid containing Astragalus(20 ml/2 L) in vivo for one week.Peritoneal macrophages function such as phagocytosis ratio、bactericidal ratio、excretion of cytokines(TNF-? and NO) and mitochondrial dehydrogenases activity(MTT assay) were examined ex vivo just before and after the treatment. In vitro,peritoneal macrophages isolated from effluent were incubated with RPMI 1640、CDF or CDF containing various concentrations of Astragalus. Then peritoneal macrophages function mentioned above were examined again and compared. Results:No significant difference was found in TNF-? level in effluent between before and after the treatment (100?63)ng/L vs (116?60)ng/L, (P=0.192). While comparing with pre-treatment, peritoneal macrophages function was improved significantly after the addition of Astragalus into dialysate (phagocytosis ratio: (34.8?12.7)% vs (43.4?9.3)%,P0.05).The results in these two groups were significantly lower than those in Astragalus groups(P0.05). While significant decreasing in NO level and mitochondrial dehydrogenases activity were observed in 8% Astragalus groups as compared with those in 2% Astragalus group(P

This study was aimed to obtain a general knowledge of physical status and its chronological changes in young Chinese recruits. 73 000 physical examination data of young male recruits were collected in 100 sample units selected by the method of cluster sampling from 31 provinces in China. Height, weight, chest circumference, and body mass index(BMI) were analyzed. The results showed that the recruits from Northeast China and North China were the tallest (170 3cm and 170 6cm on average), the heaviest (60 4kg and 61 6kg), their chest circumference largest(83 4cm and 84 6cm), and their BMI were the largest(20 8 and 21 5kg/m 2). Comparing with historical data, the average height increased 6 6cm since 1955 and 4 1cm since 1974. The body weight increased 5 6kg since 1955 and 3 5kg since 1974. Chest circumference increased slightly, the mean values of which in the three periods were 20 3, 20 1 and 19 8kg/m 2, respectively. The recruits from southwertern and south China showed least growth, and their BMI was virtually lower than before. The results of this survey indicated that a significant difference in the physical status among youth recruits from different areas in China. Lack of growth of chest circumference and BMI in youths from some areas should arouse our attention

Objective To investigate the expression and function of thymus and activation regulated chemokine (TARC) and its special receptor CCR4 at placenta villous in the first trimester placenta villous.Methods Placenta villous was collected from healthy women undergoing artificial abortion at 6 to 8 weeks of gestation,mRNA levels of TARC,CCR4 were analyzed using semi-quantitative reverse transcription (RT)-PCR methods.Immunohistochemistry assay was used to assess the protein localization and expression of TARC,CCR4.Additionally,extravillous cytotrophoblasts were isolated and cultured.Expression of TARC and CCR4 was measured by immunofluorescence assay.Invasion of cell line HTR8/SVneo was analyzed by transwell assay at concentration of 10,25,50 and 100 ng/ml of TARC matched with RPMI 1640 fetal bovine serum free eulture medium as control group.In the mean time,blocking experiment was also added to detect TARC regulating cell invasion,which were classified into four groups:control,100 ng/ml rhTARC,20 μg/ml anti-TARC + 100 ng/ml rhTARC,100 ng/ml rhTARC + 20 μg/ml IgG.The influence of 100 ng/ml TARC on expression level of integrin-α5 and integrin-β1 were measured by using western-blot assay.Results (1)In vivo assay:expression of TARC and CCR4 mRNA were detectable in first trimester placenta villous,TARC protein was localized in cytotrophoblasts,syncytiotrophoblasts and cell column especially on the distal portion,while CCR4 protein was localized on invading interstitial cytotrophobalsts.(2)In vitro assay:①TARC,CCR4 was also expressed in primary isolated extravillous cytotrophoblasts by immunofluorescence assay; ②Matrigel invasion assay demonstrated that TARC had specific dose dependent stimulatory effects on the cells invading through the matrigel precoated filter,the number of cells migration into the lower chamber were:142 ± 31 at 10 ng/ml group,161 ±46 at 25 ng/ml group,201 ±30 at 50 ng/ml group,312 ±48 at 100 ng/ml group,117 ± 33 at control group,the significant response observed from 25 ng/ml (P < 0.05)and reached a peak effect at 100 ng/ml (P < 0.01); ③Blocking experiment demonstrated that when trophoblast invasion was monitored in response to TARC neutralizing antibody (15 μg/ml) together with rhTARC 100 ng/ml.The stimulatory activity of rhTARC was completely overcome,with the cells invasion into the lower chambers were 100 ng/ml rhTARC,20 μg/ml anti-TARC + 100 ng/ml rhTARC,100 ng/ml rhTARC +20 μg/ml IgG,control:313 ±47,113 ±41,287 ±75 and 128 ±23,respectively;④Western-blot assay demonstrated that if cells were treated with 100 ng/ml rhTARC,the expression of integrin-α5 were significantly increased(P <0.01),integrin-β1 level also increased when compared with control(P <0.05).Conclusion TARC was expressed specifically at human fetal-maternal interface.Trophoblast invasion and migration mainly was regulated by up-regulation integrin-α5 and integrin-β1,which plays an role in trophoblasts differentiation and placentation.
