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).

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.

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.

Objective To assess the effect of magnetic resonance imaging (MRI) on preoperative staging of endometrial carcinoma and depth of myometrial invasion. Methods Fifty-six patients with endometrial carcinoma were underwent conventional and contrast-enhanced MR scan. The results of pathology , MRI examinations of preoperative staging and depth of myometrial invasion were assessed and compared. Results The accurate rate of MRI diagnosis in preoperative staging diagnosis was 82.1% (46/56) and the consistency check as Kappa was 0.771 (P < 0.001). Conclusions MRI may be a good diagnostic tool with high sensitivity and specificity for assessing myometrial invasion and detecting tumour extension and should be considered as a routine part of the preoperative assessment in all patients with endometrial carcinoma.

Objective To study the correlation between coronary lesion and Cystatin C (CyC),Nitric Oxide (NO)and Super oxide dismutase,accumulate the clinical experience in prevention and diagnose of Coronary Heart Disease (CHD)by analy-zing the contents of serum Cystatin C (CyC),Nitric Oxide and Superoxide Dismutase in patients with coronary lesion.Meth-ods According to their severity of coronary artery lesion,all cases were divided into four groups:Normal compared group (40 cases);Simple branch pathological group (44 cases);Double branch pathological group (43 cases):Multi-branch patho-logical group (35 cases).All cases were tested CyC,NO,SOD and hs-CRP in serum.Results The level of CyC and hs-CRP were increased gradually from normal group to multi-branch group.The level of NO and SOD were decreased gradually from normal group to multi-branch group.There were significant differences the levels of CyC,NO,SOD and hs-CRP among the four groups.Coronary lesion Gensini in the CHD patients had significant positive relationship to the level of CyC or hs-CRP respectively (r=0.473,0.429),had significant negative relationship to the level of NO or SOD respectively (r=-0.356, 0.384)(P<0.05).CyC in the CHD patients had significant positive relationship to the level of hs-CRP (r=0.458),had sig-nificant negative relationship to the level of NO or SOD respectively (r=-0.426,0.484,P<0.05).Conclusion By aggra-vation of coronary artery lesion,the level of CyC increased,reduced the contents of NO,SOD,aroused endothelial dysfunc-tion,induced occurrence and aggravation of coronary artery lesion.CyC,NO and SOD play important mark in the assistant diagnosis of the disease.
