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 .

ObjectiveTo investigate the effects of prenatal taurine supplementation on the Rho-ROCK signaling pathway activity and synaptophysin (Syp) expression in brain tissues of rats with intrauterine growth restriction.MethodsEighteen pregnant Sprague-Dawley rats were randomly divided into control group, fetal growth restriction (FGR) group and taurine group, with six rats in each group. Low-protein diet was given in FGR and taurine groups to establish an FGR model. Taurine 300 mg/(kg·d) was supplemented from gestational day 12 until delivery in taurine group. The mRNA expression levels of neurite growth inhibitor-A(Nogo-A), neurite growth inhibitor receptor (NgR), Rho-A and ROCKⅡin fetal rat brain were detected using reverse transcriptase polymerase chain reaction (n=24), which are the key signaling molecules of the Rho-ROCK signal pathway. The protein expression levels of Nogo-A and NgR were detected by Western blot (n=12). The mean optical density in Nogo-A, NgR and Syp was determined by immunohistochemistry (n=18). One-way analysis of variance and LSD-t test were used for statistical analysis.Results(1) Expression of mRNA: the expression levels of Nogo-A, NgR, Rho-A and ROCKⅡ mRNA in fetal rat brain were 4.09±1.34, 3.01±0.77, 39.89±7.71 and 7.82±1.83, respectively in FGR group, and were significantly higher than in control group (1.00±0.13, 1.00±0.10, 1.02±0.30 and 1.00±0.10) (t=4.735, 5.204, 7.682 and 10.675, allP<0.05). The expressions in taurine group (1.07±0.30, 1.20±0.27, 5.36±0.41 and 1.89±0.43) were significantly lower than in FGR group (t=4.645, 4.690, 6.687 and 9.485, allP<0.05), and there was no statistical difference between taurine group and control group (allP>0.05). (2) Expression of protein by Western blot: the expressions of Nogo-A and NgR protein in fetal rat brain were 1.51±0.09 and 0.31±0.05 in FGR group, 0.82±0.06 and 0.06±0.01 in taurine group, and 1.04±0.10 and 0.09±0.12 in control group. The expression was significantly higher in FGR group than in control group (t=9.644 and 5.285, bothP<0.05). The expression was significantly lower in taurine group than in FGR group (t=14.163 and 5.825, bothP<0.05), and there was no statistical difference between taurine group and control group (allP>0.05). (3) Positive expression of protein: the positive expressions of Nogo-A and NgR protein in fetal rat brain were 0.28±0.06 and 0.11±0.02 in FGR group, 0.10±0.02 and 0.04±0.01 in taurine group, and 0.07±0.01 and 0.04±0.01 in control group. The expression was significantly higher in FGR group than in control group (t=9.778 and 7.645, bothP<0.05). The expression in taurine group was significantly lower than in FGR group (t=8.679 and 7.413, bothP<0.05), and there was no statistical difference between taurine group and control group (bothP>0.05). The positive expression of Syp protein in fetal rat brain was 0.08±0.01 in FGR group, and was significantly lower than in control group (0.16±0.04,t=4.600,P<0.05). The expression in taurine group (0.14±0.36) was significantly higher than in FGR group (t=3.181,P<0.05), and there was no statistical difference between taurine group and control group (P>0.05).ConclusionsPrenatal taurine supplementation can improve neural axon development via down-regulating the expressions of the key molecules of Rho-ROCK signal pathway in fetal rat brain tissue.

Objective To explore the mechanism of vessel endothelial dysfunction in rats under intermittent hypoxia (IH). Methods The respiratory simulation system was used to simulate IH. Sixty C57BL/6J rats (male) were randomized into control group and IH group. The rats of IH group were exposed to IH 8 hours per day for 6 weeks. The serum levels of hypoxia inducible factor (HIF)-1a and stromal cell derived factor (SDF)-1a were assessed by ELISA. The serum levels of reactive oxygen species (ROS) were detected in two groups. The serum expression of miR-199a-5p was detected by real-time fluorescent quantitative PCR in two groups. The dual luciferase report system and point mutation test were used to verify target gene for HIF-1a. Results The serum levels of HIF-1a and SDF-1a were significantly higher in IH group than those of control group (μg/L:1.60±0.02 vs. 1.19±0.02, 1 823.00±8.97 vs. 1 444.00±17.90, P<0.01). The serum level of ROS was significantly higher in IH group than that of control group (U/mL:487.66±35.73 vs. 211.57±23.82, P<0.01). The serum level of miR-199a-5p expression was significantly lower in IH group compared to that of control group (1.31±0.07 vs. 3.47± 0.17, P<0.01). The result of dual luciferase reporter gene detection confirmed that target gene of miR-199a-5p was HIF-1a. Conclusion The serum level of miR-199a-5p is decreased first due to IH, and then its target gene (HIF-1a) is increased. HIF-1a can induce the increased level of SDF-1a, and its receptor (CXCR-4 ) is also increased. Finally, HIF-1a can increase the serum level of ROS, resulting in the endothelial dysfunction.

Phenylketonuria (PKU) is a severe autosomal recessive disease which can cause irreversible damage to patients' neural system and results in severe mental retardation.Although the institution of a lowphenylalanine (Phe) diet has been a remarkable success in preventing the devastating damage associated with untreated PKU,there are always small but consistent gap in intelligence quotient (IQ) scores and executive functioning when compared to siblings or healthy age-related control groups.During the past few years,several types of new treatment strategies,such as genetic engineering,enzyme replacement,tetrahydrobiopterin (BH4),large neutral amino acids (LNAA),low-Phe diet and liver or liver cell transplantation therapies,have been studied and improved.This paper aims to introduce the research advances in pathogenesis of PKU,the treatment methods and the related molecular mechanism.
