Objective To evaluate the contraception efficacy, mode of bleeding, side effects and other positive effects of drospirenone-ethinylestradiol (Yasmin) in healthy Chinese women. Methods This was a multicenter, randomized, control study of 768 healthy Chinese women who consulted about contraception. The subjects were randomized into Yasmin group (30 μg ethinylestradiol plus 3 mg drospirenone, 573 cases) or desogestrel group (30 μg ethinylestradiol plus 150 μg desogestrel, 195 cases) with the ratio of 3: 1. Each individual was treated for 13 cycles. Further visits were required at cycle 4, cycle 7, cycle 10 and cycle 13 of treatment. Weight, height, body mass index were evaluated at each visit. The menstrual distress questionnaire (MDQ) was given to the women at baseline, visit 3 (cycle 7) and visit 5 (after cycle 13). Results The values of basal features were similar between two groups (P> 0.05). The Pearl index (method failure) of Yasmin was 0. 208/hundred women year which was lower than that of desogestrel (0. 601/hundred women year). The mode of bleeding was similar between two groups after trial without showing any significant difference. According to MDQ subscale, the improvement of water retention and increasing appetite during inter-menstrual period and water retention and general well-being during menstrual period in the Yasmin group ( -0. 297, -0. 057, 0. 033, 0. 150 respectively) was more obvious than that in the desogestrel group ( - 0. 108, 0. 023, 0. 231, - 0. 023 respectively) with a significant difference (P < 0. 05 ). Some other values which improved in beth two groups, especially the improvement of breast tenderness and pain and skin abnormality in Yasmin group (18.0%, 89/494; 12. 6%, 62/494) was more distinct than that in desogestrel group (11.3%, 19/168; 5.4%, 9/168). The mean weight increased in desogestrel group (0. 57 kg) while it decreased in Yasmin group ( -0. 28 kg) with a significant difference (P < 0. 01 ). Conclusions Both Yasmin and desogestrel have good efficacy on contraception and similar modes of menstrual bleeding. Yasmin is better than desogestrel in terms of weight control and premenstrual syndrome of oral contraceptive.

Objective To explore the differences between baduanjin and ninth set of broadcast gymnastics in their own pulse parameters before and after intervention for 12 weeks,and to provide objective indicators for the function of Baduanjin from the perspective of pulse diagnosis.Methods 60 healthy subjects were recruited,and 50 subjects were finally included according to the dropout criteria.The subjects were divided into the experimental group and the control group by the random number table method,and different interventions were adopted.Then,the pulse diagnosis of the two groups of subjects was collected,and the impact of the interventions on the viscera was judged by analyzing the Pulse Graph Parameters and contribution.Results The characteristic parameters of the experimental group include 8 time domain parameters(left Chi,left Guan,right Cun,etc.)and 9 frequency domain parameters(left Guan,left Chi,right Guan,etc.),which are mainly distributed in the left Cun,left Guan,left Chi,and right Guan;the characteristic parameters of the control group included 6 time domain parameters(left Cun,left Guan,right Chi,etc.)and 11 frequency parameters(left Guan,left Chi,right Guan,etc.),which were mainly distributed in left Chi,right Chi,and left Guan.Conclusion Practicing Baduanjin can significantly affect pulse diagram,and the accuracy and specificity after intervention are higher than those of the control group.Baduanjin has a certain influence on the circulation of qi and blood in the human meridians,and its mechanism of action may be related to affecting the overall circulation of qi and blood.In the experimental group,Baduanjin had a significant effect on the heart,liver,gallbladder,and kidneys,while the control group had the most obvious changes in the kidneys.For the overall intervention and coordination of the viscera,the Baduanjin group had better effects than the ninth broadcast gymnastics group.

Objective To investigate the efficacy and mechanism of action of Compound Chaijin Jieyu Tablets (复方柴金解郁片, CCJJYT) in rats with insomnia complicated with depression. Methods Seventy-two Sprague-Dawley rats were randomly assigned into eight groups: the control, chronic unpredictable mild stress (CUMS), sleep deprivation (SD), CUMS + SD, positive drug (venlafaxine hydrochloride + diazepam), CCJJYT high-dose (CCJJYT˗2×), medium-dose (CCJJYT˗1×), and low-dose (CCJJYT˗0.5×) groups, with nine rats in each group. Depression-like behavior was evaluated by body weight, food intake, and behavioral tests such as the sucrose preference test (SPT), open field test (OFT), forced swimming test (FST), and pentobarbital-induced sleep test (PST). Hematoxylin-eosin (HE) staining and Golgi-Cox staining were used to observe changes in pathological tissue and synaptic morphology, respectively. Enzyme-linked immunosorbent assay (ELISA) was used to detect the contents of orexin-A and acetylcholine. The expression levels of orexin receptor 1 (OXR1), melatonin receptor 1 (MT1A), melatonin receptor 2 (MT1B), acetylcholinesterase (AChE), and choline acetyltransferase (ChAT) were detected by immunohistochemistry and Western blot. Results In the present study, rats in the model group showed significant behavioral changes as well as a reduction in hippocampal dendritic branch length and synaptic number, along with increasing the content of orexin A and acetylcholine (P< 0.05), and altered expression levels of OX1R, MT1A, MT1B, ChAT, and AChE in the hippocampus and prefrontal cortex after modeling (P < 0.05). CCJJYT can improve depressive insomnia behavior and synaptic plasticity of rats (P < 0.05), which is similar to that of the positive drug group. It can also decrease the content of orexin A and acetylcholine, and reduce the expression levels of OXR1 and ChAT in hippocampus and prefrontal cortex (P < 0.05), and increase the expression levels of MT1A, MT1B, and AChE proteins (P < 0.05). Conclusion CCJJYT has good antidepressant and insomnia effects, probably through the regu-lation of orexin-A, melatonin, and acetylcholine content in hippocampus and prefrontal cortex of rats, improving synaptic plasticity and thus exerting antidepressant and insomnia effects.
