Objective:To observe the effects of muscle regions of meridians needling method combined with auricular point sticking on pain and lumbar range of motion in patients with chronic nonspecific low back pain. Methods:A total of 100 patients with chronic nonspecific low back pain were randomly divided into a control group and an observation group,with 50 patients in each group.Both groups received auricular point sticking treatment,while the control group received additional conventional acupuncture treatment,and the observation group received additional muscle regions of meridians needling method.The total effective rate of the two groups was compared after 4 weeks of treatment.Before treatment and after 1 week and 4 weeks of treatment,the visual analog scale(VAS)score was used to assess the degree of low back pain,and the modified-modified Schober(MMS)score was used to evaluate the lumbar range of motion. Results:There was statistical significance in comparing the total effective rate between the two groups(P<0.01).During the treatment process,as the number of treatments increased,the VAS score gradually decreased,and the MMS score gradually increased in both groups.After 1 week and 4 weeks of treatment,the VAS score in the observation group was lower than that in the control group(P<0.01),and the MMS score in the observation group was higher than that in the control group(P<0.01).During the treatment period,no serious adverse reactions occurred in either group. Conclusion:Based on auricular point sticking treatment,muscle regions of meridians needling method is more effective than conventional acupuncture in treating chronic nonspecific low back pain since it is able to significantly reduce the pain and improve the lumbar range of motion.

Objective To analyze the gonadal hormone and seminal plasma of patients with abnormal semen liquefaction and investigate the influence mechanism in order to provide guidance for the diagnosis and treatment. Methods 152 men of childbearing age were divided into two groups according to the liquefaction time (cut?off point: 60 minutes). Routine semen parameters,gonadal hormone and seminal plasma were tested and compared between the above groups. T?test was applied to compare individual gland function (pH value,neutralα?glycosidase,fructopyranose,seminal plasma zinc and citric acid) and gonadal hormone (FSH,LH,PRL,T and E2). Logistic regression analysis was adopted to probe the influencing factors for abnormal semen liquefaction. Results Seminal pH value (7.47 ± 0.13 vs. 7.32 ± 0.18),citric acid(51.12 ± 12.95 vs. 83.11 ± 33.46)and FSH (4.40 ± 1.03 vs. 4.85 ± 1.50)levels were significant different between the two groups (P < 0.05),but the other indexes showed no significant difference. Correlation regression analysis showed that semen liquefaction capacity has correlative relationship with seminal plasma fructose (OR=2.644),citric acid (OR=0.922),serum T (OR=1.029) and E2,while no correlative relationship with other indexes. Conclusions Correlation between two glands (seminal vesicle and prostate) and balance in the two hormones (T and E2) influence the liquefaction time. Specific causes should be distinguished before diagnosis.

Objective To evaluate the value of serum E2 levels during COH in predicting IVF-ET outcome. Method Data from 311 IVF-ET cycles received long protocol were collected and analyzed according to E 2 levels 5 days after stimulation:Group A (E2≤500 pmol/L), Group B (500 2 000 pmol/L). Results In groups with E2>1 000 pmol/L, the conditions of oocyte and embryo are higher than E2<1 000 pmol/L. With the increase of E2 levels, period cancellation rate increases. When E2> 2 000 pmol/L, the pregnancy rate become lowest. Conclusion E2 levels among 1 000~1 500 pmol/L during early COH predicts a better pregnancy outcome.

Objective To compare the effect of kidney-tonifying blood-activating recipe (KBR) and Aescuven Forte Tablets ( AFT) in improving the sperm quality of varicocele-induced male sterility, thus to optimize the therapeutic therapy for varicocele-induced male sterility. Methods A total of 102 varicocele-induced male sterility with abnormal sperm parameters after conservative treatment were randomized into KBR group (N=53) and AFT group ( N=49) . KBR group was given KBR plus natural vitamin E and AFT group was given AFT plus natural vitamin E, and the treatment lasted for 8 continuous weeks. Before and after treatment, the quality of seminal fluid was analyzed, sperm quantization parameters such as total number of sperm (TNS) , total number of progressive motility sperm ( TNPS) , total number of normal form sperm ( TNNS) and total number of nor mal form and progressive motility sperm ( TNNPS) were observed, and the improvement rate of sperm quantization parameter was compared. Results (1) Before treatment, the differences of TNS, TNPS, TNNS and TNNPS were insignificant between the two groups ( P>0.05) . After treatment, TNNS was not improved in AFT group ( P>0.05) , but TNS, TNPS, TNNPS were much improved in both groups ( P<0.01 compared with those before treatment) . The improvement of KBR group was superior to that of AFT group ( P<0.05) . ( 2) The improvement rate for TNS, TNPS, TNNS, TNNPS was 90.57%, 79.25%, 67.92%, 77.36%in KBR group, and was 75.51%, 73.47%, 28.57%, 61.22% in AFT group respectively. The improvement rate for TNS and TNNS in KBR group was superior to that in AFT group ( P<0.05 or P<0.01) . Conclusion Varicocele-induced male sterility patients usually have the syndrome of kidney deficiency and blood stasis, so KBR, which has the function of tonifying kidney and activating blood, has synergistic action on the effect of AFT in improving sperm quality of varicocele-induced male sterility patients.

Treatment of adult femoral neck fracture is still a great challenge faced by trauma orthopedists. As treatment effects can be infleunced by multiple factors, like age, gender and preoperative physical condition, they may vary with different treatment schemes. Classification of femoral neck fractures plays an important guiding role in choosing a proper treatment scheme and judging the prognosis. The current classic clinical classification systems for femoral neck fractures include Garden, AO/OTA and Pauwels classifications. Since the recent progress in science and technology has put more advanced technologies into clinic application, such as CT, MRI and Digital Subtraction Angiography (DSA), new ways of classification have appeared. However, each classification has its own shortcomings which need to be improved. This paper reviews the research progress in classification of adult femoral neck fractures and their treatment principles.
