Objectiveto observe whether electro-acupuncture (EA) is better in improving hormone levels among women with diminished ovarian reserve (DOR) compared with oral medicine [Chinese herbs with or without hormone replacement therapy (HRT)] that is often used in gynecology clinics in China.Methodseligible participants entered the EA group or medication group according to their preferences. Participants in the EA group received EA treatment, and participants the medication group received herbal decoction alone or combined with HRT. Reproductive hormone levels of the participants were tested before and during treatment in both groups.Resultsa total of 80 women with DOR were screened and 57 cases were included (29 in the EA group and 28 in the medication group) in the final analysis. The differences in the change from baseline between the EA and medication group in mean follicle-stimulating hormone (FSH) levels were -6.6 (95% CI, -17.03 to 3.72), (P = 0.848) and -7.09 (95% CI, -15.86 to 1.66), (P = 0.539) at weeks 12 and 24, respectively. The proportion of women with regular FSH levels in the EA and medication group was 51.3% vs 32.1% at week 12 (P = 0.134) and 51.3% vs 25.0% at week 24 (P = 0.038).ConclusionEA might influence regulating the levels of FSH, luteinizing hormone (LH), estrogen and the FSH/LH ratio, and no difference was found between the effects of EA and oral medicine in changes of reproductive hormone levels.

Mechanism of moxibustion regulation on cellular apoptosis in rat’s precancerous lesion of primary hepatocellular carcinoma

Objective: To investigate the mechanism of moxibustion in regulating cellular apoptosis in rat’s precancerous lesion of primary hepatocellular carcinoma (HCC). Methods: Seventy-four rats were randomly allocated to normal group, model group and moxibustion group, and the diethylic nitrosamine (DEN) was used to establish HCC model. Moxibustion with moxa cone which is as big as a grain of wheat was performed on acupoint Zusanli (ST 36), 3 cones for each acupoint and 0.5 mg for each cone, the treatment was given once a day, totally 16 weeks. Then the changes in the body weight, liver weight and thymus weight, a morphological change in the liver tissue and changes in γ-GT and GST were observed; Immunohistochemical staining method was adopted to observe the tendency of changes in relevant apoptosis genes such as C-myc, N-ras and mutant type P53, and the influence of moxibustion on cell cycle modulation genes such as cyclinD1, CDK4 and p16. Results: Moxibustion could reduce the activities of γ-GT and GST in the blood, obviously decrease the protein expression of relevant apoptosis genes such as C-myc, N-ras and mutant type P53 and markedly inhibit the over-expression of relevant cell cycle modulation genes such as cyclinD1 and CDK4 and the mutation of cell cycle modulation gene p16. Conclusion: Moxibustion might play a certain role in relieving HCC precancerous lesion and its action mechanism might be related to the regulation on partial apoptosis genes.

Effectiveness of nourishing Yin and tonifying Yang sequential therapy in combination with Climen on diminished ovarian reserve: a retrospective study

OBJECTIVE: To evaluate the clinical efficacy of nourishing Yin and tonifying Yang sequential therapy(NYTYST) in combination with the Western Medicine Climen in treating diminished ovarian reserve(DOR).METHODS: From September 2014 to September2016, 46 patients with DOR who received NYTYST and Climen(treatment group) and 51 patients who received Climen only(control group) at the Jiangsu Provincial Traditional Chinese Medicine Hospital(Nanjing, China) were retrospectively reviewed. Before and at 3 months after treatment, serum levels of follicle-stimulating hormone(FSH), FSH/luteinizing hormone(LH), estradiol(E2), and anti-Mullerian hormone(AMH), the antral follicle count(AFC), stromal peak systolic velocity(PSV), symptom scores,and the clinical effectiveness rate were measured and compared between the two groups.RESULTS: After treatment, serum levels of FSH,FSH/LH and E2, and symptom scores were significantly decreased compared with before treatment(all P 0.05) in the two groups. AMH levels, AFC,and PSV were significantly increased after treatment compared with before treatment in both groups(all P 0.05). Serum levels of FSH, FSH/LH,and E2 after treatment were significantly lower in the treatment group than in the control group(all P 0.05). However, AMH levels and the AFC were significantly higher after treatment in the treatment group than in the control group(both P 0.05). The clinical effectiveness rate was significantly higher in the treatment group than in the control group(87% vs 68.6%, P 0.05).CONCLUSION: NYTYST combined with Climen may be more effective in treating DOR than Climen alone.

Premature ovarian failure treated with mild moxibustion and western medication

ObjectiveTo explore the clinical therapeutic effect on premature ovarian failure (POF) treated with the combination of mild moxibustion and western medication.MethodsA total of 66 patients were divided into a control group and an observation group according to random number table, 33 cases in each one. In the control group, the conventional western medication was administered. In the observation group, besides the treatment as the control group, mild moxibustion was supplemented at Guānyuán (关元CV4), Qìhăi (气海CV6), Píshū (脾俞BL20) (bilateral) and Shènshū (肾俞BL23) (bilateral). The duration of treatment was 3 menstrual cycles in either group. Before treatment and on the 9th day of menstruation after 3-menstrual cycle treatment, the number of antral follicles and ovarian volume were detected by color Doppler ultrasound respectively. Before treatment and on day 2 to 4 of menstruation after 3-menstrual cycle treatment, the levels of serum estrogen (E₂), follicle-stimulating hormone (FSH), interleukin-21 (IL-21) and vascular endothelial growth factor (VEGF) were determined separately and the therapeutic effect was evaluated in two groups separately.ResultsThe effective rate was 93.94% in the observation group and was 72.73% in the control group (P < 0.05). After treatment, the number of antral follicles and ovarian volume were increased as compared with those before treatment in the patients of two groups (both P < 0.05). After treatment, the number of antral follicles and ovarian volume in the observation group were higher than the control group (both P < 0.05). After treatment, the levels of serum E₂ and FSH were improved as compared with those before treatment in the two groups (both P < 0.05). The levels of serum E₂ and FSH in the observation group were better than the control group after treatment (both P < 0.05). The levels of serum IL-21 and VEGF after treatment did not change obviously as compared with those before treatment in the control group (both P > 0.05). But in the observation group, the levels of serum IL-21 and VEGF after treatment changed apparently as compared with those before treatment (both P < 0.05) and the levels of these two indicators after treatment were better than the control group (both P < 0.05).ConclusionThe combined treatment of mild moxibustion with western medication achieves the definite therapeutic effect on POF and it increases the number of antral follicles and ovarian volume and regulates sex hormone level, which is probably related to the regulation of serum IL-21 and VEGF.

Effects of different courses of moxibustion treatment on intestinal flora and inflammation of a rat model of knee osteoarthritis

Objective: This study was done to determine the effects of different courses of moxibustion on a rat knee osteoarthritis(KOA) model, and explore the dose–effect relationship of moxibustion on KOA from the perspectives of intestinal flora and inflammatory factors.Methods: Wistar rats were randomly divided into five groups: normal, model, moxibustion for 2 weeks,moxibustion for 4 weeks and moxibustion for 6 weeks groups(n = 5 each group). A KOA rat model was induced by monosodium iodoacetate, and ...     

Regulatory effect of acupuncture and moxibustion on the hematopoiesis of leukopenia model in rats

目的：研究针刺或艾灸膈俞穴对低白细胞模型大鼠提升白细胞和增强骨髓增殖功能的作用。方法：选用Wistcr大鼠为实验对象，用环磷酰胺（CTX）腹腔注射造成白细胞减少及免疫功能抑制模型，分组处理后，在不同时相进行白细胞计数，并计数骨髓有核细胞数，以评估针刺或艾灸膈俞穴的升白及增强骨髓造血功能的作用。结果：针刺、艾灸膈俞穴及常规西药治疗均可显著提升白细胞、增加骨髓有核细胞计数，且艾灸膈俞穴组疗效优于针刺膈俞穴组及常规西药对照组（P〈0．05）。结论：艾灸膈俞穴可明显提升低白模型大鼠外周血白细胞数和骨髓有核细胞计数．
