ObjectiveTo compare the efficacies between conventional acupuncture plus acupoint application and conventional acupuncture plus TDP in treating dysmenorrhea due to blood stagnation led by cold.MethodSixty patients were randomized into two groups, 31 cases in the treatment group and 29 cases in the control group. The treatment group was intervened by conventional acupuncture plus acupoint application, while the control group was by conventional acupuncture plus TDP. Before and after the intervention, McGill Pain Questionnaire was adopted to compare the Pain Rating Index (PRI) score, Visual Analogue Scale (VAS) score, and Present Pain Index (PPI) score, and the therapeutic efficacy was also compared.ResultThe recovery rate was 58.1% in the treatment group, significantly higher than 24.1% in the control group (P<0.01); the total effective rate was 90.3% in the treatment group, significantly higher than 62.1% in the control group (P<0.01), indicating that the therapeutic efficacy of the treatment group was more significant than that of the control group. Before the intervention, there were no significant differences in comparing the PRI, VAS, and PPI scores between the two groups (P>0.05), suggesting the comparability. After the intervention, there were significant differences in comparing the PRI, VAS, and PPI scores between the two groups (P<0.05), and the PRI, VAS, and PPI scores were markedly decreased in the treatment group.ConclusionConventional acupuncture plus acupoint application can improve dysmenorrhea symptoms and reduce patient’s pain, and can produce a more significant efficacy compared with conventional acupuncture plus TDP.

Conclusion Small dose dexmedetomidine combination with sufentanil administration in PCIA after laryngeal carcinoma surgery could acquire satisfied analgesic effect , also could eliminate the patient anxious mood , enhance the security in the perioperative period and improve the patients' satisfaction degree , whichis very suitable for multi mode analgesia acquirement.

OBJECTIVETo compare the difference in the efficacy on thoracic facet joint disorder between the combined therapy of electroacupuncture and manual reduction and the simple manual reduction.

METHODSOne hundred and sixty patients were randomized into an electroacupuncture and manual manipulation group (group A) and a simple manual manipulation group (group B), 80 cases in each one. In the group A, Ashi points and three pairs of Jiaji (EX-B 2) bilateral to the painful sites were selected. The perpendicular puncture was used at Ashi points, the oblique puncture was used at Jiaji (EX-B 2) and connected with electric stimulation for 20 min, additionally, the corresponding manual reduction was adopted at the sites of facet joint disorder. In the group B, the simple manual reduction was applied to the affected sites. Acupuncture was given once every day, the manual reduction was applied once every 10 days. The treatment of 10 days made one session. The efficacy was analyzed statistically at the end of two sessions of treatment. Before and after treatment, McGill pain scale was adopted for the value statistical analysis. PRI score, VAS score and PPI score of patients were calculated before and after treatment and compared in the two groups. The efficacy was compared between the two groups.

RESULTSThe curative rate was 56.3% (45/80) in the group A, which was better than 18.8% (15/80) in the group B (P< 0.01). The total effective rate was 95.0% (76/80) in the group A, which was better than 76.3% (61/80) in the group B (P<0.01). The scores of PRI, VAS and PPI after treatment were all improved significantly in the two groups (all P<0.05), in which, the results in the group A were better than those in the group B (PRI: 4.00 +/- 0.97 vs 5.44 +/- 1.16, VAS: 3.29 +/- 0.72 vs 3.87 +/- 0.81, PPI: 1.07 +/- 0.74 vs 1.64 +/- 0.90, all P<0.05).

CONCLUSIONThe combined therapy of electroacupuncture and manual manipulation achieves the superior efficacy on thoracic facet joint disorder as compared with the simple manual manipulation. The combined therapy relieves the symptoms of thoracic facet joint disorder and reduces the severity of disorder.

AIM: To study the effect of ginkgolide B on high glucose-induced human lens epithelial cell (HLEC) apoptosis.
METHODS: The high glucose-induced HLEC model was established. Different concentrations of ginkgolide B were intervened. Cell viability was assayed by MTT assay, morphology of cell apoptosis was observed by hochest33258 staining. Cell ultrastructural changes were detected by transmission electron microscopy. Expressions of apoptosis - related factors caspses - 3 and caspase-9 were tested by colorimetric detection.
RESULTS: High glucose inhibited the activity of HLECs, induced apoptosis reaction of HLECs, caused high expression of apoptosis factors in cells; while ginkgolide B inhibited the decrease of cell viability induced by high glucose, decreased the HLEC apoptosis and reduced the expression of apoptosis factors Caspase-3 and Caspase-9.CONCLUSION: Ginkgolide B may inhibit the expression of caspses-3 and caspase-9 then effectively inhibited high glucose-induced apoptosis in HLECs.

Binding activity and biologic effect of a novel alpha-melanocyte-stimulating hormone analogue were tested on cells transiently expressing the human melanocortin-1 (MC1), MC3, MC4, and MC5 receptors. The human MC1 and MC5 receptor genes were cloned into the expression vector pcDNA3. 1/ myc-his(-) B. The vectors were transferred to HEK-293 cells by the calcium phosphate method. Stable receptor populations were generated using G418 selection (900 microg x mL(-1)) for subsequent bioassay analysis. K(i) values of the novel alpha-MSH analogue for MC1, MC3, MC4, and MC5 receptors were obtained in competition with [125I]-NDP-MSH for binding studies. The cyclic AMP level was tested by using [3H]-cyclic AMP kit. It is showed that K(i) values of the novel alpha-MSH analogue for MC1, MC3, MC4, and MC5 receptors were (0.159 +/- 0.040), (35.430 +/- 6.743), (19.293 +/- 2.780) and (2.230 +/- 0.670) nmol L(-1), respectively. Its EC50 values for MC1, MC3, MC4, and MC5 receptors were (0.45 +/- 0.07), (7.80 +/- 0.65), (2.55 +/- 0.23) and (0.33 +/- 0.09) nmol L(-1), respectively. In these tests, the novel alpha-MSH analogue is a MC1R and MC5R selective agonist.

OBJECTIVETo investigate the prevalence and characteristics of sexual dysfunction in patients with chronic prostatitis (CP) in the high altitude area.

METHODSA total of 637 CP patients randomly recruited from different urologic clinics were divided into 4 groups according to their living altitudes. The subjects were scored on the National Institute of the Health Chronic Prostatitis Symptom Index (NIH-CPSI), the International Index of Erectile Function-5 (IIEF-5), the Chinese Index of Sexual Function for Premature Ejaculation (C-ISFPE) and the questionnaire on ejaculatory difficulties from the University of Washington Symptom Score.

RESULTSIn the 637 CP patients, the overall incidences of premature ejaculation (PE), erectile dysfunction (ED) and difficult ejaculation (DE) were 28.4%, 17.6% and 23.9%, respectively, 9.9% with PE, ED and DE simultaneously. With the increase of the living altitude, the scores on IIEF-5 (P = 0.032) and C-ISFPE (P = 0. 047) were obviously decreased, and the incidences of PE (P = 0.047), ED (P = 0.046) and DE (P = 0.019) markedly elevated. Those with PE or ED experienced worse symptoms at a higher altitude (r = 0.249 or 0.267, P < 0.05). The differences were all statistically significant.

CONCLUSIONThe prevalence and severity of sexual dysfunction are positively correlated with the living altitude among CP patients.
