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.

AIM:To investigate the inhibitory effects of recombinant human Mullerian inhibiting substance on cell proliferation in human ovarian carcinoma cells (OVCAR8 and SKOV3 cell lines). METHODS:The expression of MISIIR protein and the localization of MISIIR protein were analyzed by Western blotting and confocal spectral microscopy,respectively. Cell apoptosis and cell cycle were detected by flow cytometry (FCM). Cell viability was determined via MTT method. Clone formation test was used to detect oncogenicity in vitro.RESULTS:The MISIIR protein expression in OVCAR8 cells but not in SKOV3 cells was observed. MISIIR expression was seen on the OVCAR8 cell surface and in the cytoplasm with both antibodies. After treated with rhMIS for 48 h,the cell viability was significantly decreased in OVCAR8 cells. rhMIS inhibited the oncogenicity of OVCAR8 cells greatly. The cell apoptosis of OVCAR8 cell exposed to 10 mg/L rhMIS was (31.3±2.1)%,and OVCAR8 cells in the G_1 phase were increased by (70.4±3.0)%. Compared to SKOV3 cells the differences were significant (P<0.01). CONCLUSION:Recombinant human Mullerian inhibiting substance suppresses the growth of MISIIR-positive ovarian cancer cells by inducing apoptosis and cell cycle arrest. We predict that rhMIS might be a new target to treat human ovarian malignancies.

Purpose To discuss the feasibility of evaluating left ventricular systolic function in patients with acute anterior myocardial infarction (AAMI) with three-dimensional speckle tracking imaging (3D-STI). Materials and Methods Thirty AAMI patients were examined with 3D-STI technique in terms of left ventricular longitudinal strain (LS), radial strain (RS), circumferential strain (CS), area strain (AS), global longitudinal strain (GLS), global riadial strain (GRS), global circumferential strain (GCS) and global area strain (GAS). The results were compared with those of 30 healthy persons and the strain values in normal segments of those AAMI patients. The threshold, sensibility and specificity of those parameters in diagnosing myocardial infarction were analyzed. Results Compared with healthy group, LS reduced in 12 out of 17 segments (12/17), RS reduced in 10/17, CS in 9/17 and AS in 11/17;they mainly focused in the base segment, middle and apex of anterior wall, the base segment and the middle of anterior septal, the apex of aboral septal, and the middle segment, apex of the lateral wall. The GLS, GRS, GCS and GAS were all lower than those in healthy group (differences with statistic signiifcance:P<0.05). In AAMI patient, LS, RS, CS and AS in the infarcted segments were lower compared with those in the normal segments (differences with statistic signiifcance:P<0.05). ROC curve analysis showed that the sensitivity of LS, RS, CS and AS were 89.2%, 79.0%, 77.9%, 85.3%, respectively in the diagnosis of myocardial infarction, and the speciifcity were 65.8%, 71.0%, 66.9%and 92.3%, respectively. The sensitivity of the GLS, GRS, GCS and GAS were 91.2%, 74.0%, 68.9%, 85.3%, respectively in the diagnosis of myocardial infarction, and the speciifcity were 69.8%, 71.0%, 76.9%and 93.3%, respectively. Conclusion 3D-STI can detect the strain values of LV segments efficiently and accurately so as to discriminate normal and infracted segments, which provides a reliable measurement to evaluate the extent of the infarction of the patients with acute anterior wall myocardial infarction.

Objective To study the effects of Danshen Shujingwan on cervical cord compression in rats. Methods 60 healthy male SD rats of 8 weeks old were randomly divided into 6 groups: sham group (N group), model group (M group), DSW groups of high, medium and low dosages, and group treated with Jingfukang (J group), with 10 rats in each. The cervical cord compression models were established by transplanted silica gel. From 7 d after model establishments, the rats were respectively treated with drug by gavage for 30 d. They were observed pathologically. Results The extent and scope of damage were less in the treatment groups than in the model group (P<0.001), while the number of normal neurons remained more in the treatment groups (P<0.01).Conclusion DSW can decrease the damage after cervical spinal cord compression, protect the neurons from injuring.

Objective To analyze the clinical features of juvenile dermatomyositis (JDM) combined with soft-tissue calcification. Methods Forty-seven patients with JDM combined with soft-tissue calcification (soft-tissue calcification group) were retrospectively analyzed, and they were contrasted with 89 patients with non-calcification (non-calcification group). Results The rates of Gotton signe, muscle contracture and joint dysfunction in soft-tissue calcification group were significantly higher than those in non-calcification group:87.23% (41/47) vs. 43.82% (39/89) and 68.09% (32/47) vs. 21.35% (19/89), and there were statistical differences (P<0.05). The dosage of glucocorticoid (conversion of prednisone measuring more than 1.5 mg/kg), rate of using immunodepressant, level of creatine kinase in soft-tissue calcification group were significantly lower than those in non-calcification group:17.02%(8/47) vs. 68.54%(61/89), 25.53%(12/47) vs. 88.76%(79/89), (566.45±240.41) U/L vs. (1 680.12±656.50) U/L, and there were statistical differences (P<0.05). Conclusions The patients with JDM combined with Gotton signe are more prone to soft-tissue calcification. The rate of muscle contracture and joint dysfunction in soft-tissue calcification patients is significantly higher than that in non-calcification patients. For the patients whose creatine kinase are not obviously elevated, they are more prone to soft-tissue calcification. Early active application of glucocorticoid and immunodepressant therapy can reduce or prevent the occurrence or development of late calcium deposition.
