OBJECTIVETo observe the clinical efficacy on constipation predominant irritable bowel syndrome (IBS-C) treated with acupuncture for regulating the mind and strengthening the spleen and the impacts on the quality of life in the patients.

METHODSSixty patients of IBS-C were randomized into two groups. In the acupuncture group (30 cases), acupuncture was applied to Tianshu (ST 25), Zusanli (ST 36), Shangjuxu (ST 37), Taichong (LR 3), Sanyinjiao (SP 6), Yintang (GV 29) and Baihui (GV 20), once a day, 5 treatments a week and 4 weeks treatment as one session. In the western medication group (30 cases), lactulose oral solution was prescribed, 15 mL each time, three times a day, 4 weeks treatment as one session. The symptom grade scale and the quality of life scale (IBS-QOL) were adopted to observe the changes in clinical symptoms and quality of life before treatment, after treatment and 2-month follow-up after treatment in the patients of the two groups separately.

RESULTS(1) Clinical symptom score: the difference in the symptom score at each time point was significant statistically in intra-group comparison (P < 0.01). In 1 week, 4 weeks of treatment and 2 months after treatment, the clinical symptom scores in the acupuncture group were lower than those in the western medication group (P < 0.05, P < 0.01). (2) IBS-QOL score after treatment was improved as compared with that before treatment in the two groups (P < 0.01). The improvement of IBS-QOL at 2 months after treatment in the acupuncture group was apparently superior to the western medication group (P < 0.05). (3) The total effective rate was 90.0% (27/30) in the acupuncture group and was 83.3% (25/30) in the western medication group. The overall efficacy in the acupuncture group was better than that in the western medication group (P < 0.01).

CONCLUSIONAcupuncture for regulating the mind and strengthening the spleen significantly relieves the clinical symptoms of IBS-C and improves QOL of patients. The total efficacy is superior to lactulose oral solution and presents a certain of long-term efficacy.

OBJECTIVETo investigate the influence of parathyroid hormone and estrogen on alveolar bone metabolism of castrated female rats.

METHODSSixty-six female Wistar rats which were healthy and 4 months old were divided into two groups, with group SHAM (n = 18) and group ovariectomy (OVX) (n = 48). After 8 weeks of ovariectomy, the osteoporosis model was confirmed by examing 8 ovariectomized and sham-operated rats. The rest 10 rats in group SHAM were the control group (group A). The rest 40 rats in group OVX were divided into ovariectomized group (group B), ovariectomized and treated with estrogen (group C), ovariectomized and treated with parathyroid hormone (group D), ovariectomized and treated with estrogen and parathyroid hormone (group E) at random with 10 in each group. Group A and B injected physiological saline (1 mL x kg(-1)), group C injected estradiol benzoate (10 microg x kg(-1)), group D injected parathyroid hormone (20 microg x kg(-1)), group E injected parathyroid hormone (20 microg x kg(-1)) and estradiol benzoate (10 microg x kg(-1)). The intraperitoneal injection were maken every other day to rats in each group, which continued for 8 weeks. The bone mineral density (BMD), bone histomorphology and serum Ca, P, alkaline phosphatase (ALP) were measured after therapy.

RESULTSAfter 8 weeks of ovariectomy, the lumbar BMD of ovariectomized rats were significantly declined compared with those of the sham-operated rats (P < 0.05). Eight weeks later after the drug use, the BMD, %Tb.Ar, Tb.Th, Tb.N in group C, D, E were slightly elevated compared to group B, especially the group E (P < 0.05). Serum calcium and phosphorus values did not change significantly (P > 0.05). ALP values in group B was significantly higher than that in group A (P < 0.05).

CONCLUSIONIntermittent application of parathyroid hormone in small doses can increase alveolar BMD of castration rats and improve their bone structure. And it can have synergy effects on the treatment of osteoporosis if it is used combining with estrogen.
