In order to explore the effect of Yaoliuan capsule in the prevention and treatment of vaginal bleeding after drug-induced abortion and menses recovery after drug-induced abortion, 323 cases of gestation period < or = 49 days and without contraindication, were divided randomly into study group (168 cases, taking Yaoliuan capsule) and control group (155 cases, taking placebo capsule). The results showed that in the study group, there were 161 cases (95.8%) of complete abortion, 7 cases (4.2%) of incomplete abortion; In the control group, there were 146 cases (94.2%) of complete abortion, 6 cases (3.9%) of incomplete abortion, 3 cases (1.9%) of abortion failure. The vaginal bleeding time was 5-25 days (mean 10.8 days) in study group, while that was 6-62 days (mean 19.1 days) in control group. The menstrual cycle was 30.5+/-5. 2 days and 33.8 d+/-8.6 days respectively in study and control groups. The menstrual period was 6.1+/-3. 5 days and 9.9+/-5.1 days respectively in study and control groups. Yaoliuan capsule is an effective drug to prevent and treat vaginal bleeding following drug-induced abortion, promote menstruation recovery and prevent pelvic infection.

Objective To observe the effect of Bushen Yiqi Hexue Recipe(Recipe to reinforce kidney,replenish qi and harmonize blood)on the endometrial gland apoptosis in blastocyst implantation dysfunctional mice.Methods The mice models of blastocyst implantation dysfunction were made and divided into control,model and treated groups with 30 in each.Pregnancy rate,number of implantation blastocysts,the expression of proliferating cell nuclear antigen(PCNA),bax,bcl-2 and activated Caspase-3 were observed.Results Compared with the control group,pregnancy rate and mean implanted blastocysts in the model group were remarkably reduced.Compared with the model group,pregnancy rate and mean implanted blastocysts in the treated group were significantly improved(P

To explore the role of connexin43 (Cx43) in gap junctional intercellular communication (GJIC) and propagated sensation along meridians, the expression of Cx43 in the rat epithelial cells and fibroblasts was studied both in vitro and in vivo. With the in vitro study, the rat epithelial cells and fibroblasts were cultured together, and the localization of Cx43 was detected by immunohistochemistry and indirect immunofluorescent cytochemistry and under confocal microscopy. And the expression of Cx43 on the surface of the cells was examined by flow cytometry. With the in vivo examination, 20 SD rats were randomized into control group (n = 10) and electrical acupuncture group (EA group, n = 10). EA ( 0.5-1. 5 V, 4-16 Hz , 30 min) was applied to "Zusanli" acupoint for 30 min at rat's hind paw, the localization of Cx43 was immunohistochemically detected. The immunohistochemical staining and indirect immunfluorescent cytochemistry showed that Cx43 was localized on the surface of the cells and in the cytoplasm. The relative expression level of Cx43 on the cellular membrane surfaces of the rat epithelial cells and fibroblasts, as determined by FACS, were 13.91% and 29.53% respectively. Our studied suggested that Cx43 might be involved in GJIC and propagated sensation along meridians.

Objective To investigate the influence of acupuncture on promoting rat blastocyst nidation with Cx43 expression at the acupoints silenced, and to relate Cx43 with acupuncture's effects. Methods Ma-ted female rats were randomly divided into five groups: normal control, model, acupuncture, interference-control and interference. Mifepristone was used to induce a model of nidation disorder, and RNA interference technology was used to silence the expression of Cx43 at acupoints. P-Cx43-shRNA (1) was injected locally into the acu-points of rats in the interference group, and P-con-shRNA was injected in the interference-control group. Acu-puncture was administered to the acupuncture, interference-control and interference groups for 7 days. On the 8th day of pregnancy, the quality of blastocysts, pregnancy rates, and the average amount of blastocysts in each group were observed. Results ①The mRNA and protein level of Cx43 at the zusanli (ST36) acupoints in the interference group were significantly lower than in the acupuncture group ( P<0.05, P<0.01). There was no significant difference between the interference-control group and the acupuncture group. ② Compared with the normal control group, the quality of blastocysts in the model and interference groups was bad, and the amount was less. Their size was comparatively small, they were inhomogeneous, poorly distributed and had poor blood supply. The results improved in the acupuncture group and the interference-control group compared with the model group. ③The pregnancy rates in the normal control, model, acupuncture, interference-control and inter-ference groups were 100% , 50% , 75% , 75% , and 50% respectively, but these differences were not statisti-cally significant. ④The average amount of blastocysts in the model and interference groups was significantly less than in the normal group (P≤0.01). Compared with the acupuncture group, the average amount of blastocysts in the interference group was lower (P≤0.05). Conclusion Acupuncture can improve the quality and quan-tity of blastocysts in a rat model of nidation disorder. Local injection of Cx43 shRNA expression vector can si-lence the expression of Cx43 in acupoints and markedly influence acupuncture's effect. This demonstrated that Cx43 was involved in acupuncture's effects.

Objective To investigate the effects of xuanzhi analgesic tablets on plasma levels of 6-keto-prostaglandin Flα(6-K-PGFlα) and thromboxane B2(TXB2) in rats with acute blood stasis. Methods Sixty SD rats were divided into six groups randomly, namely normal control, model control, positive control, xuanzhi analgesic tablets at 1. 36, 2. 72, and 5. 44 g·kg-1 groups. The rat model of blood stasis syndrome was caused by subcutaneous injection of adrenaline incorporated with ice-bathing. The effects of xuanzhi analgesic tablet on 6-K-PGFlαand TXB2 were observed. Results Compared with the normal control,plasma level of 6-K-PGFlα was significantly reduced(P<0. 01) and that of TXB2 in the model control was evidently increased(P<0. 01). Three dosages of xuanzhi analgesic tablets significantly raised 6-K-PGFlαlevel(P<0. 05)and lowered TXB2 level (P<0. 05). Conclusion Xuanzhi analgesic tablets significantly adjust plasma levels of 6-K-PGFlαand TXB2in rats with acute blood stasis. Xuanzhi analgesic tablets can coreect the imbalance between PGI2 and TXA2 through increasing 6-K-PGFlαand desearing TXB2 levels.

Objective To observe the differences in functional areas of the brain in response to two different acupuncture techniques using functional magnetic resonance imaging (fMRI).Methods Deqi and non-deqi acupuncture were performed on twenty healthy right-handed volunteers.fMRI was conducted in the process of acupuncture.The experiment adopted a single-chunk design and the procedure contained periods of stimulation and rest.The brain regions stimulated during deqi and non-deqi acupuncture were assessed using xjview software.Results After acupuncture at the Zusanli point (ST36),differences in activity were observed between the deqi and non-deqi groups in the language,sports,perception and limbic systems.Conclusions ①Under deqi conditions,acupuncture at ST36 increases circulation and the activation of brain areas dealing with language,sports,perception and the limbic system.This may be one of the mechanisms by which acupuncture can improve aphasia,coordination and perception.②Under deqi conditions acupuncture at ST36 decreases circulation and deactivates brain areas associated with the limbic system.This may explain acupuncture's analgesia and regulation of autonomic nerve and endocrine function,its amelioration of internal organ functions and regulation of immunologic function.

Objective:To study on effect of Jiantai Liquid on progesterone receptor(PR)in the uterus at the nidation stage in the mouse with disturbance of blastocyst nidation.Methods:The gestational mice were randomly divided into a normal group,a model group and a Chinese drug group.Mifepristone was used for inducing disturbance of blastocyst nidation in the mice,which were interfered with Jiantai Liquid.At the eighth week of pregnancy,the mice were killed and morphological changes of the endometrium were observed,and PR expression in the uterus was detected with immunohistochemical method and PR and PRmRNA expressions were detected with Western blot and PT-PCR methods.Results:The endometrium showed maldevelopment in the model group and normal development in the Chinese drug group,similar to the normal group;the gland,the PR expression range and intensity of PR expression in the interstitial substance in the Chinese drug group increased as compared with the model group(P0.05);expressions of PR protein and gene in the Chinese drug group were significantly higher than those in the model group(P0.05).Conclusion:Jiantai Liquid can promote development of the endometrium and improves blastocyst nidation via regulating expressions of PR and PRmRNA in the uterus in the mice with disturbance of blastocyst nidation.

In order to observe the effect of Bushenantai recipe on the expression of endometrial leukemia-inhibitory factor (LIF) in mice with embryonic implantation dysfunction (EID), 120 Kunming mice post coition were randomized into three groups: normal control group, model group and traditional Chinese medicine group (TCM group) (n=40 in each group). Uterus was collected on the pregnancy day (Pd) 4, 5, 6 after an intravenous injection of Evan's blue. The endometrium was dyed by Evan's blue and the mean points of response were observed on Pd 5. The expression of LIF mRNA and protein was detected by RT-PCR and immunohistochemistry respectively and analyzed statistically by image system. The results showed that the number of implantation sites in model group was remarkably less than in normal control group and TCM group. There was no significant difference between normal control group and TCM group. The expression of LIF mRNA and protein in model group was delayed. Bushenantai recipe could increase the expression of LIF mRNA and protein in endometria of mice with EID. It was suggested that Bushenantai recipe could improve embryo implantation of mice with EID by promoting the endometrial LIF expression and endometrial decidualization.

To observe the differences in psychological status between Bell's palsy (BP) patients and healthy subjects, and to examine the relationship between psychological factors and the severity of BP, we conducted a case-control, multi-center clinical investigation. A total of 695 subjects were assigned to the case group (n=355) and the control group (n=340). House-Brackmann grading system and Facial Disability Index (FDI) were adopted to assess the BP patients; Kessler Psychological Distress Scale (K10) and 16 Personality Factor (16PF) scale were employed to evaluate the psychological distress and personality profiles of all subjects. Two independent samples t test was used to compare the differences between cases and controls, and to compare the differences among different BP patients. Pearson correlation analysis was used to examine the relationship between psychological factors and severity of facial paralysis. The results showed that psychological distress (K10) in case group (27.09±5.80) was significantly higher than that in control group (13.43±3.02) (t=-37.219, P=0.000). The scores of personality factor Warmth (A), Openness to Change (Q1), Self-Reliance (Q2) were lower in cases than in the controls (P<0.01, P<0.05, P<0.05, respectively), whereas the scores of Sensitivity (I), Vigilance (L), Apprehension (O), and Tension (Q4) were significantly higher in cases than in the controls (P<0.05, P<0.01, P<0.01, P<0.01, respectively). In addition, the psychological distress was significantly higher in female patients, severe (HB score IV-VI) patients, and subacute (onset time 72-168 h) patients compared with that in male patients, mild (HB score I-III)patients, and acute (onset time[Symbol: see text]72 h) patients (P<0.05). The scores of personality factor in female patients, severe patients, and subacute patients were also significantly different from male patients, mild patients, and acute patients (P<0.05). The result of Pearson correlation analysis showed that psychological factors (K10, personality A, F, L, N, O, Q4) were closely related to HB scores. We are led to conclude that the psychological status between BP patients and healthy people are different; psychological distress and personality factors are closely associated with severity of facial paralysis.
