Journal of Acupuncture and Tuina Science 2015;(6):398-404
Luteinized unruptured follicle syndrome (LUFS), a specific type of ovulation disorder, is for a cause of female infertility. Acupuncture therapy has a good effect for LUFS. In order to understand the clinical effects and research situation of acupuncture therapy for LUFS, the author analyzed and reviewed the relevant literature. It was indicated by the findings that acupuncture therapy and integrative therapy of acupuncture and Chinese herbs have good therapeutic effect for this disease. Acupuncture therapy has the effect to promote ovulation. By the therapeutic principle to tonify the kidney and circulate blood, acupuncture therapy mostly was adopted in the period of ovulation. The acupoints are mostly selected from the lower abdomen and lower limbs, possibly based upon syndrome differentiation at the same time. The needling techniques are of certain characteristics. But, the issues of low quality, un-standardized inclusive, exclusive criteria and effective criteria still exist in the current clinical study.

Objective To study the effects of mosapride and domperidone on the pulmonary infection of acute stroke patients lying in bed and with nasal feeding. Methods Eighty-nine acute stroke patients lying in bed and with nasal feeding were divided randomly into the treatment group (47 cases) and the control group (42 cases). The control group was treated routinely,and the treatment group was treated with mosapride 5 mg and domporidone 20 mg thrice a day for 4 weeks, besides routine therapy. The incidence rate of pulmonary infection, gastric residual volume (GRV) and the number of cases with gastric contents remaining after 3 hours of nasal feeding were studied. All data were analyzed statistically. Results In the treatment group, 13 cases had pulmonary infection,and the incidence rate was 27.66%(13/47). In the control group,25 cases had pulmonary infection,and the incidence rate was 59.52% (25/42). There was significant difference between the two groups (P < 0.01 ). Three hours after nasal feeding,24 cases with gastric contents remaining were discovered in the treatment group,and GRV was (50.80±15.38) ml. Two hundred and thirty-seven cases with gastric contents remaining were discovered in the control group, and GRV was (112.17±32.54) ml. Significance differences were also detected between the two groups (P<0.01). Conclusion As for the acute stroke patients lying in bed and with nasal feeding,mosapride and domperidone can remarkably cut down the pulmonary infection upon common treatment.

Objective:To survey the status quo of job burnout among rural general practitioners and to analyze its influencing factors.Methods:A total of 2 805 rural general practitioners in three counties in southwest Shandong province were enrolled in the study. The survey was conducted with a basic information questionnaire and the Maslach Burnout Inventory-Human Service Survey (MBI-HSS). The influencing factors of job burnout were analyzed by Pearson chi-square test (χ2) and binary logistic regression model.Results:A total of 2 272 rural general practitioners completed the survey with a completion rate of 81.0%. The rates of middle or high job burnout in the dimensions of emotional exhaustion, depersonalization and reduced personal sense of achievement were 55.1%(1 251/2 272), 34.0%(772/2 272) and 91.3%(2 075/2 272), respectively. Binary logistic regression model showed that working hours/week ≥ 60 h ( OR=1.341, 95 %CI:1.057-1.702, P<0.05), monthly shift times ≥20 ( OR=1.434, 95 %CI:1.182-1.739, P<0.05), daily consultation time≥13 h ( OR=1.294, 95 %CI:1.055-1.589, P<0.05), daily consultation of 11-20 patients ( OR=1.317, 95 %CI:1.075-1.614, P<0.05), no part-time job ( OR=1.583, 95 %CI:1.201-2.087, P<0.05), insomnia ( OR=2.638, 95 %CI:2.225-3.128, P<0.05), feeling depressed at work ( OR=3.170, 95 %CI:2.661-3.776, P<0.05) were risk factors for emotional exhaustion; participation in public health services ( OR=1.485, 95 %CI:1.155-1.910, P<0.05), being married ( OR=2.273, 95 %CI:1.198-4.313), no part-time jobs ( OR=1.677, 95 %CI:1.276-2.203, P<0.05), insomnia ( OR=1.487, 95 %CI:1.211-1.827, P<0.05), and feeling depressed at work ( OR=1.642, 95 %CI:1.339-2.015, P<0.05) were risk factors for depersonalization; working hours/week ≥ 60 h ( OR=2.089, 95 %CI:1.454-3.002, P<0.05), daily consultation time ≥ 9 h ( OR=2.495, 95 %CI:1.748-3.561, P<0.05), insomnia ( OR=2.061, 95 %CI:1.519-2.796, P<0.05), and feeling depressed at work ( OR=1.894, 95 %CI:1.383-2.593, P<0.05) were risk factors for reduced personal achievement. Protective factors included monthly income ≥3 000 Yuan ( OR=0.589, 95 %CI: 0.353-0.982, P<0.05) and monthly shift of 10-19 times ( OR=0.581, 95 %CI:0.411-0.820, P<0.05). Conclusion:The overall job burnout among rural general practitioners in southwest Shandong province is serious, especially the depersonalization and the reduction of personal sense of achievement. It is suggested to improve the salary, reduce the working intensity, optimize the working hours, and pay attention to their physical and mental health for rural general practitioners to alleviate the current situation of their occupational burnout.
