Objective To observe and compare the regulating effect between electroacupuncture and sham electroacupuncture on the symptoms of menopausal transition and levels of estradiol (E2), follicle-stimulating hormone (FSH), and luteinizing hormone (LH), for evaluating the clinical efficacy of electroacupuncture in mitigating the relevant symptoms of menopausal transition. Method Thirty eligible subjects with menopausal transition were randomized into a treatment group and a control group, 15 cases in each group. The treatment group was intervened by electroacupuncture at the ordinary acupoints, while the control group was by electroacupuncture at non-meridian points. The E2, FSH, and LH contents were detected after intervention and at the 20th week during the follow-up study, the flush score and Menopause Rating Scale (MRS) were evaluated respectively after 4-week and 8-week treatment and at the 20th week and 32nd week during the follow-up study, and the safety of electroacupuncture was also estimated.Result The flush and MRS scores were significantly changed after 4-week and 8-week treatment and at the 20th week and 32nd week during the follow-up study in both groups compared to that before the treatment in the same group (P<0.01,P<0.05). There was a significant difference in comparing the changes of MRS score after 8-week treatment between the two groups (P<0.01). There were significant differences in comparing the changes of flushing scores between the two groups after 8-week treatment and at the 20th week and 32nd week during the follow-up study (P<0.01). The serum levels of E2, FSH, and LH were significantly changed in the treatment group after 8-week treatment (P<0.05). There were significant differences in comparing the changes of FSH and LH levels between the two groups after 8-week treatment (P<0.05). The difference in comparing the change of serum E2 level between the two groups at the 20th week during the follow-up study was statistically significant (P<0.05). Conclusion Electroacupuncture can improve the flushing intensity and produce a benign regulation on the relevant hormone levels in menopausal transition, though this regulation is insignificant when the treatment terminates.

Objective To study the clinic features and prognosis of juvenile rheumatoid arthritis (JRA)-associated iridocyclitis.Methods Ten cases of JRA -associated iridocyclitis choosed from 107 cases with JRA were reviewed and analysed.Results Polyarticular( n =9) and pauciarticular( n =1) were observed among JRA -associated iridocyclitis.Four were acute cases and all were recovered.Secondary glaucoma ( n =1) and ablepsia( n =1) were find in the chronic cases of 6,respectively.Conclusions Iridocyclitis is a common complication of JRA. Most of them are polyarticular group. The acute cases have better results compared to the chronic cases which often have more complications such as glaucoma,cataract, et al .

Purpose:To study the influence of treatment with high dose progesterone on telomerase activity in patients with endometrial adenocarcinoma.Methods:20 patients were treated for adenocarcinoma of endometrium with high dose progesterone and the change of telomerase activity in tumor tissue was examined by PCR-TRAP ELISA before and after treatment.Results:The average A value of tumor telomerase before and after treatment were 0.3636(0～1.11) and 0.1134 (0～0.556),respectively.It shows that telomerase activity in tumor was decreased by treatment with progesterone (P

Sucking mice, 2～3 day after birth, were intraperiton eally inoculated with 0.05mL F1M10 of Chen Strain Hantaan virus. At diff erent t ime point after inoculation, the brains were taken, routinely fixed and embedded in paraffin for preparing 5 μm serial sections. Traditional and confocal immun ochemical detection of viral antigens and heat shock protein 70 were performed t o exp lore the cerebral stress response after viral infection. The results showed that HSP70 immunoreactivities could be stably detected in the viral antigen positive neurons, but not in the viral antigen negative or uninfected control tissues. B y confocal microscopic examination, the HSP70 and viral antigens were colocolize d in the neuronal cytoplasm. Our result, comparable to our previous findings in human tissues and culture cells, indicated that Hantavirus infection can induce the expression of HSP70 in the infected cells, and HSP70 expression might be n ecessary but not sufficient to keep the cell survival.

Objective To investigate the detection rate and possible factors of hyperhomocysteinemia(HHcy) in children with chronic kidney disease(CKD).Methods The clinical data of children with CKD between July 2012 and September 2016 in the Department of Pediatrics,Peking University First Hospital were retrospectively collected.The homocysteine(Hcy) level of patients were measured.The other data included the general information,diagnosis and laboratory test results.Results Seventy-six pediatric patients with CKD were enrolled including 49 boys and 27 girls.The average age of the patients was (9.9±3.4) years old.The main cause of the patients in the study was primary glomerulopathy(48.7%,37/76 cases),and the rest were congenital and inherited glomerular diseases(36.8%,28/76 cases),secondary glomerular diseases(9.2%,7/76 cases)and renal tubular diseases(5.3%,4/76 cases).Fifty patients (65.8%,50/76 cases) had normal level of Hcy which was 10.40(7.30,11.62) μmol/L.Twenty-six patients(34.2%,26/76) were detected with HHcy whose Hcy level was 17.93(16.76,24.11) μmol/L.The detection rate of HHcy in CKD stage 1,stage 2,stage 3,stage 4 and stage 5 was 13.9%(5/36 cases),22.2%(2/9 cases),50.0%(4/8 cases),57.1%(4/7 cases) and 68.8%(11/16 cases) respectively,and the detection rate increased with CKD stages and the difference was statistically significant (χ2=17.574,P<0.001).The level of Hcy was 10.05(7.04,12.47) μmol/L,11.75(10.78,16.44) μmol/L,13.73(10.09,18.23) μmol/L,15.81(11.12,20.71) μmol/L and 17.39(11.86,24.76) μmol/L in CKD stage 1,stage 2,stage 3,stage 4 and stage 5,respectively.The Kruskal-Wallis test revealed that the distribution of homocysteine in CKD stages had statistically significant difference(P=0.001).Multiple linear regression model showed that creatinine clearance was an independent predicator of HHcy.Conclusions In this study of the CKD patients,the detection rate of HHcy was high and increased with the progression of CKD.HHcy is mainly influenced by creatinine clearance in CKD.The level of Hcy should be monitored regularly in children with CKD and HHcy should be treated with proper measures.
