Effect of Bushenwenyanghuayu decoction on nerve growth factor and bradykinin/bradykinin B1 receptor in a endometriosis dysmenorrhea mouse model.

OBJECTIVE: To observe the effects of Bushenwenyanghuayu decoction (BD), a Traditional Chinese Medicine (TCM), on the serum concentration of nerve growth factor (NGF) and bradykinin (BK), and protein and mRNA levels of NGF and bradykinin B1 receptor (BKB1R) in a mouse model of endometriosis dysmenorrhea. METHODS: Seventy-five experimental female BALB/c mice were randomly divided into five groups, 15 mice each: sham, model, BD high dose (61.67 g/kg), BD low dose (15.42 g/kg), and gestrinone (0.4 mg/kg) groups. All the mice except for those in the sham group underwent auto-transplantation surgery and were gavaged estradiol valerate (0.5 mg/kg, daily for 12 days) after surgery. On the 12th day, 1 h after administration, writhing response was induced by intraperitoneal injection of oxytocin at 2 U/mouse. The writhing frequency and latency were recorded and the volume of the ectopic foci was measured. The concentration of serum NGF and BK was detected by enzyme-linked immunosorbent assay, the protein expression of NGF and BKB1R was tested by immunohistochemistry and western blotting, and NGF and BKB1R mRNAs were detected by real-time PCR. RESULTS: Compared with the model group, the volume of the ectopic foci in the treatment groups was significantly lower (P < 0.01), the writhing frequency was decreased (P < 0.05), and the writhing latency was prolonged (P < 0.01). Compared with the sham group, serum NGF and BK levels in the model group were significantly increased (P < 0.01). There were positive correlations for writhing frequency among the NGF and BK groups (P < 0.01). The serum NGF and BK levels were significantly lower in the treatment groups than the model group (P < 0.05). The protein expression of NGF, BKB1R was significantly decreased in the treatment groups compared with the model group (P < 0.01). NGF and BKB1R mRNA expression was significantly decreased in the treatment groups compared with the model group (P < 0.01). CONCLUSION: NGF and BK/BKB1R may play an important role in the development of endometriosis-associated dysmenorrhea, and BD was found to inhibit the development of endometriosis and relieve dysmenorrhea by influencing NGF and BK/ BKB1R mRNA and protein levels.

Effects ofCangfu Congxian Decoction on mRNA Expression of IGF-1R in Human Mural Granulosa Cells of PCOS Patients / 中国中医药信息杂志

Objective To explore the effects ofCangfu Congxian Decoction on the mRNA expression of IGF-1R in human mural granulosa cells;To explore the action mechanism for the treatment of polycystic ovary syndrome (PCOS) patients.Methods Totally 48 patients undergoing IVF-ET were randomly divided into treatment group and control group by random number table, 24 cases in each group. Patients in the control group accepted GnRHa/FSH/hCG stimulation, while the treatment group tookCangfu Congxian Decoction orally on the basic treatment of the control group. Serum E2, LH, and P concentration on HCG injection day, number of ovum, high quality embryo rate and clinical pregnancy rate were evaluated. The mRNA expression of IGF-1R on mural granulosa cells in the mature follicle was detected by real-time PCR.Results Compared with the control group, there was no significant difference in serum E2, LH, and P concentration on HCG injection day of treatment group (P>0.05), while the treatment group had higher high quality embryo rate than that of the control group (P0.05). The mRNA expression of IGF-1R on granulosa cells in treatment group was significantly higher than the control group (P<0.01).Conclusion The mechanism ofCangfu Congxian Decoction for treating PCOS is up-regulating the mRNA expression of IGF-1R in mural granulosa cells and increasing high quality embryo rate.

Relationship between Trace Elements and Asthenia TCM Syndromes in Embryonic Development Stops / 中国中医药信息杂志

Objective To study the relationship between the asthenia TCM syndromes in embryonic development stops and the level of zinc, iron, copper, magnesium, phosphorus, calcium in serum, and provide thoughts for assisting reproduction and preventing miscarriage. Methods Totally 100 patients of embryonic development stops were selected randomly (6-10 weeks gestation) to be the investigated group, with other 100 cases of live fetus as the control group. The contents of trace elements in serum were detected with atomic absorption spectrometry. Results The levels of trace elements in embryonic development stops patients were generally lower than the control group. The serum iron in patients with spleen deficiency syndrome, and serum zinc and iron in patients with kidney deficiency syndrome were significant lower (P<0.05). Conclusion The contents of trace elements in serum have relationships with asthenia TCM syndromes in embryonic development stops. It should be paid attention to supplementing trace elements during the gestation period. For patients with deficiency of kidney and spleen, the supplement of zinc and iron should be given greater prominence.

Modern Literature Study on the Feature and Objectivization of Symptom Distribution of Asthenia Cold Syndrome / 中医杂志

Objective Through the statistical analysis on literature on asthenia cold syndrome in recent ten years,to comprehend the present situation of studies on the feature and objectivization of symptom distribution of asthenia cold syndrome.Methods Collect literature on asthenia cold syndrome from the periodicals of traditional Chinese medicine and integrated traditional and western medicine from the year 1996 to 2006.The described features and objective indices of symptom distribution of this syndrome were systematically analyzed and summarized.Results In the literature,the diagnostic criteria of asthenia cold syndrome were made mainly by the authors themselves,few referring to others',being different in the descriptions of symptom distribution.The researches on objectivization indices were scattered,most of which took the single or multiple index(es) as subject(s).Conclusion Cold limbs,tiredness,aversion to cold,and loose stools are possibly significant in the diagnosis of asthenia cold syndrome.The way of the studies on diagnostic criteria and its objectivization of asthenia cold syndrome need to be improved.
