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.

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.

Objective To screen the optimal dose of Tangtong Formula in vitro. Methods RSC96 Schwann Cells were cultivate by DMEM mediums which contains different concentrations of glucose (5–125 mmol/L). The prevention effects of Tangtong Formula at different concentrations (0.25, 0.5, 0.75, 1.0, 1.5, 2.0, 3.0, 5.0 mg/mL) on the proliferation of RSC96 Schwann Cells induced by high glucose were detected. After the RSC96 Schwann Cells were cultivated in 100 mmol/L and 125 mmol/L high glucose mediums for 72 h, the apoptosis of RSC96 Schwann Cells was detected by flow cytometry Annexin V/PI, and the apoptosis rate was calculate; the proliferation situation of RSC96 Schwann cells in different times was detected by CCK-8 method. Results RSC96 Schwann cells were in apoptosis after being intervened by 100 mmol/L and 125 mmol/L high glucose mediums. The apoptosis rates were respectively(7.46±0.96)％ and(16.53±1.01)％, with statistical significance compared with control group (P<0.01). Different concentrations of Tangtong Formula could alleviate the inhibitory effect of high glucose on the proliferation of RSC96 Schwann cells, and the threshold concentration of Tangtong Formula in 24 h was 0.25 mg/mL. The concentrations of Tangtong Formula in 0.5 mg/mL, 1.0 mg/mL, and 1.5 mg/mL could inhibit the apoptosis of RSC96 Schwann cells induced by high glucos, compared with 125 mmol/L high glucose group, the apoptosis rate of RSC96 Schwann cells decreased significantly (P<0.05, P<0.01). Conclusion Among three different doses, when the dose of Tangtong Formula is in 1.5 mg/mL, the effects on inhibiting apoptosis are the best.

However, the surgeons-related factor is the highest influencing factor. The cognition of anesthesia-related factors and surgeons-related factors differs in different operating rooms.

Peripheral nerve impairment is a common complication in surgery, clinical researchers always do nerve sutrure using microsurgical technique and adjuvant treatment to improve peripheral nerve regeneration. Western medicine used usually adjuvant drugs, such as neurotrophic factors,are limited by their defects in clinical application. Traditional Chinese medicines (TCMs) classifies peripheral nerve impair as flaccidity Zheng and arthromyodynia, and considers that it is the result of stagnant blood block in the meridians and vessels, deficient of Qi and blood and disuse of bones and muscles. So, drugs usually have the function of invigorating vital energy, activating blood circulation and dredging collaterals. Mono-drugs include astragalus, Salvia miltiorrhiza, Astragali Radix, Epimedii Folium and so on. Extracts of TCMs have Ginkgo Folium, Cervi Cornu Pantotrichum, Achyranthis Bidentatae Radix, and so on. To be ready for further study and development, TCMs which can promote the peripheral nerve regeneration were reviewed by the literatures of the latest years.
