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 .

To investigate the effect of the anti-endotoxic part of Radix Isatidis on the expression of moesin mRNA in murine tissues induced by lipopolysaccharide (LPS), the sample solution of F(022) part from Radix Isatidis was intraperitoneally administered to experimental mice, and the lipopoly-saccharide (LPS) were injected into the tail vein, and then the tissues of liver, kidney and spleen were colleted and cut into slices. The mRNA was detected by moesin mRNA hybridization in situ. The staining results were observed under microscope. It was found that moesin mRNA expression was increased in the tissues of liver, kidndy and spleen in mice treated with LPS, while in the mice pre-treated with F(022) part from Radix Isatidis, the LPS-induced moesin mRNA expressions in these tissues were inhibited in a dose-dependant manner. Our study showed that F(022) part from Radix Isatidis can inhibit the LPS-induced expression of moesin mRNA in the tissues of liver, kidney and spleen in mice.

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.
