However, few studies focus on HIV-related heterosexual risk behaviours among the majority Yi population. The objectives of this study were to explore the characteristics of an egocentric sexual network and estimate the prevalence of casual sexual behaviour. Yi villagers （n= 108）, aged 15-35 years, who reported having had sex within the previous year were interviewed as to their sexual behaviours and networks. In-depth interviews and focus group discussions provided supplementary information on sexual norms. Logistic regression analysis was used to calculate unadjusted odds ratios （ORs） and 95% confidence intervals （CIs）. Most of the respondents reported having had casual sex at some time in their life, and 66.7% reported multiple sexual partnerships. Only 21.3% reported ever having used a condom. During the study year, a total of 137 partners were involved in 153 sexual partnerships. Among the reported sexual partnerships, 67.3% originated from a casual sexual relationship. For network members in components of size ≥3, 56,9% were involved in concurrent sexual partnerships. Having never been married （OR： 2.11; 95% CI： 1.03-4.33） and younger age （OR： 0.89; 95% CI： 0.83-0.95） were both associated with being in a component of size ≥3. Size （OR： 2.99; 95% Ch 1.17-7.66）, pair （OR： 0.54; 95% Ch 0.039-0.74）, the number of weak components of the egocentric sexual network （OR- 30.04; 95% Ch 6.47-139.46） and gender （OR. 0. 19; 95% Ch. 0.06-0.67） were all associated with being in concurrent sexual partnerships. HIV-related interventions for the Yi ethnic minority in Sichuan province must therefore address concurrent sexual partnerships and promote condom use.展开更多

Methods： A total of 90 cases with KOA were randomized into an observation group and a control group, 45 in each group. Those in the observation group conducted Yi Jin Jing exercise once a day; whereas those in the control group received no therapies at all. The therapeutic effects have been assessed after 8 weeks of observation. Results： After 8 weeks of observation, the isokinetic muscle strength of quadriceps femoris muscle in the treatment group was substantially improved, whereas there were no distinct changes of isokinetic muscle strength of quadriceps femoris muscle in the control group. Conclusion： Yi Jin Jing exercise can definitely improve the quadriceps femoris muscle strength of patients with KOA. It is therefore an effective intervention method for KOA.展开更多

Those in the observation group practiced Yi Jin Jing（Sinew-transforming Qigong Exercises） plus tuina therapy; whereas those in the control group received only tuina therapy. Tuina therapy was conducted every other day, 20 min every time for 1 month and Yi Jin Jing（Sinew-transforming Qigong Exercises） was conducted once a day for 1 month. The therapeutic effects were assessed by visual analogue scale（VAS） and Constant-Murley scale.Results： After treatment, the VAS score and Constant-Murley scale were substantially improved, showing statistical significances（P〈0.01）; the Constant-Murley scale in the observation group was better than that in the control group,showing a statistical significance（P〈0.01）; the effective rate in the observation group was higher than that in the control group, between-group comparison showed a statistical significance（P〈0.01）.Conclusion： Yi Jin Jing（Sinew-transforming Qigong Exercises） plus tuina and tuina alone have a verified effect in treating SP,and the former can achieve a better effect than the later.展开更多

Serum amylase, SOD and MDA were determined on postoperative day 1, 2, 4 and 7. The animals were sacrificed on day 7. SOD and MDA in organs were determined, and pathological changes in pancreas were observed.RESULTS As compared with control group, the serum level of amylase (734U/L vs 2783U/L) and MDA (7.8nmol/ml vs 14.8nmol/ml) in Chinese medicine group were decreased on day 7 (P＜0.05), while SOD increased significantly (281nU/ml vs 55nU/ml, P＜0.01), and similar changes occurred in MDA and SOD in organs, especially in the pancreas; the pathological changes in the pancreas were alleviated as well.CONCLUSION 'Qing Yi Tang' is effective in clearing OFRs and alleviating pathological changes in ANP.展开更多
