Objective To investigate the effects of HRT on endometrium of postmenopausal women.Methods 53 cases of postmenopausal vaginal bleeding(PMB),from Jan,1995 to Dec.1999 treated by HRT were selected to make a comparison with the other 60 cases of PMB without HRT during the corresponding period.Both groups had integrated ultrasonic and pathological data and getting information from succedent inspection.Results The rates of the endometrial carcinorma incidences that happen in the HRT group were non-HRT group were 5 66% and 8 33% respectively,which had little significant.While the occurring rates of inflammation were 1 89% and 16 67% respectively,a significant difference between the both existed here.Conclusions With HRT,the various symptoms of post menopause women can be efficiently improved.It is safe and effective in short term.But a close monitoring is absolutely necessary for its long term effect(5 years or more).

The relationship between tumour necrosis factor-alpha (TNF-alpha) gene polymorphism and inhibitory effects of triptolide on TNF-alpha production from peripheral blood mononuclear cells (PBMC) of healthy humans was investigated. Genomic DNA from 41 healthy people was typed for TNF-alpha--308 polymorphism by allele-specific polymorphism chain reaction (AS-PCR). The TNF-alpha concentration in the supernatant was measured by ELISA. The results showed that the production of TNF-alpha from TNF-alpha--308 non-G/G genotype PBMC was higher than that from TNF-alpha--308 G/G genotype PBMC after stimulated by LPS. Triptolide could lower the production of TNF-alpha from G/ G genotype PBMC, but had no effect on the level of TNF-alpha from non-G/G genotype PBMC. It was concluded that TNF-alpha gene polymorphism was related to the TNF-alpha production from triptolide-inhibited PBMC culture in healthy humans.

Objective The aim of the study is to discuss the application value of HA330-Ⅱ microporous resin plasma adsorption in liver support and the treatment of complications of chronic severe hepatitis.Methods The treatment group has 41 patients of chronic severe hepatitis B,which were treated for 3 times by HA330-Ⅱ microporous resin plasma adsorption.We compared the improvement of symptom,the fadeamay and rebound of icterus,the change of hepatic encepllalOpathy and brain oedema,the change of blood routine test,blood ammonia level,blood-gas analyzing result,cruor index,inflammatory factors(IL-1b,IL-6,IL-8,TNF-α,etc.),side effects,etc.The control group has 37 patients of the same type.Results HA330-Ⅱ microporous resin plasma adsorptioin is partly effective for the improvement of symptom,improvernent rate 43.9%,and without new discomfort due to the treatment. It obtains some extent fadeaway of icterus which has a low rebound,reduce TBiL(17.83±3.65)% and there be no statistics difference of rebound.It lowers the blood ammonia level and improves the hepatic encephalopathy and brain oedema.It absorbs cytokine IL-8.Atthough it has some extent effect to albunfin,blood paltelet,haemoglobin.Conclusion HA330-Ⅱ microporous resin plasma adsorption has good application value in the treatment of chronic severe hepatitis B.It is a new treatment choice of severe hepatitis.

BACKGROUND: The effect of Chinese traditional medicine 3'-meisoindigo as well as indimbin derivatives on normal immunocytes is less reported while it is used for antitumor.OBJECTIVE: To investigate the effect of 3'-meisoindigo on the proliferation of the splenocytes and thymocytes of C56BL/6 mouse.DESIGN, TIME AND SETTING: The randomized cytopathology observation was performed between August 2007 and January 2008 at Zhujiang Hospital of Southern Medical University, Guangzhou, Guangdong Province, China.MATERIALS: C57BL/6 mice, clean, male, 6-8 weeks old, weighing (20±2) g.METHODS: The thymus gland and the spleen of C57BL/6 mice were ground to get the single-cell suspension and cells were treated by 5, 10, 15, 20 and 25 μ mol/L 3'-meisoindigo,respectively. Cells without any drug treatment were used as blank control and cells treated by concanavalin A were used as positive control.MAIN OUTCOME MEASURES: Proliferation of splenocytes and thymocytes detected using MTT method; IL-12 activity in culture supematant detected using ELISA method; the cell cycle, apoptosis rate, cell death rate and intracellular reactive oxygen species level detected using flow cytometry; the mRNA level of bcl-2 and cdk2 detected using reverse transcription-polymerase chain reaction; the expression rate of Bcl-2, CDK2 and Bax detected using fluorescence microscope.RESULTS: After treating for 24 hours, 15, 20 and 25 μ mol/L 3'-meisoindigo can significantly inhibit the proliferation of thymocytes and splenocytes (P < 0.05) and the inhibition was dose-dependent and time-dependent. Cells resumed proliferation after removing the 3'-meisoindigo, although they had been treated by 25 μ mol/L 3'-meisoindigo for 72 hours. The secretion of IL-12 was markedly reduced in all 3'-meisoindigo groups versus control groups at each time point (P < 0.05). 15 μ mol/L 3'-meisoindigo could decrease the mRNA expression level of apoptosis-related protein bcl-2 and cyclin cdk2 gene, decrease the expression level of BCL-2 protein and CDK protein, increase Bax expression level, decrease Bcl-2/Bax ratio markedly and started apoptosis.15 μ mol/L 3'-meisoindigo arrested cells in the G2/M stage of the thymocytes and splenocytes, and intracellular reactive oxygen species level elevated dose-dependently and time-dependently.CONCLUSION: In certain concentration range, 3'-meisoindigo can reversibly inhibit the proliferation of thymocytes and splenocytes of C57BL/6 mouse and can inhibit IL-12 secretion in parallel, and start apoptosis.

AIM: To explore whether the inhibitory effect of triptolide on IL - 1β production by PBMC is asso ciated with IL - 1β gene polymorphisms. METHODS: IL - 1β gene polymorphism was analyzed in 31 healthy volunteers. From genomic DNA, the C - T polymorphism at IL - 1 β - 511 was typed by PCR - RFLP. Meanwhile the IL - 1 β was also measured in the supernatants of the cultured and stimulated peripheral blood mononuclear cells (PBMC) by ELISA. RE SULTS: After LPS stimulation in PBMC cultures of healthy subjects, the secretion levels of IL - 1 β in 9 volunteers who carried IL - 1β -511 T/T genotype were higher than in volunteers who are not T/T genotype (P <0.05). Triptolide sup pressed the production of IL - 1β significantly in LPS - treated human PBMC carried C/C and C/T genotype ( P < 0.05 ), but this significant inhibitory effect of triptolide was not seen in T/T genotype ( P > 0.05 ). CONCLUSION: The gene polymorphism at IL - 1β - 511 was related to the production of IL - 1β, and the inhibitory effect of triptolide on the produc tion of IL - 1β was different in C/C, C/T, T/T genotype of IL - 1β -511, which may be one of the reasons for the phe nomenon that people respond differently to triptolide.
