Objective: To observe the clinical efficacy of acupuncture treatment for migraine. Methods: Forty cases were randomly allocated to a treatment group and a control group, 20 cases in each group. Cases in the treatment group were treated with acupuncture, while cases in the control group were treated with oral Sibelium. After that, the changes of cerebral blood flow were observed before and after treatment. Results: There was significant difference in clinical efficacies between two groups (P<0.05). There were also significant differences in arterial blood flow velocities of before and after treatment. Acupuncture can produce substantial differences (P<0.05) in blood flow velocities of vertebral artery (VA), middle cerebral artery (MCA) and anterior cerebral artery (ACA) during an increased flow rate. It can also produce statistical differences in blood flow velocities of VA during a decreased flow rate (P<0.05). Conclusion: Acupuncture can effectively alleviate the pain of migraine sufferers and exert a two-way regulation on the cerebral blood flow.

Objective To evaluate the security and efficacy of combination of epristeride and terazosin for treatment of benign prostatic hyperplasia (BPH). Method One hundred and eighty-four patients with BPH were treated by epristeride for 6 months and terazosin for 1 month, the efficacy and complication were observed. Results After 6 months treated, compared with before treated, the common symptoms improved, the residual urine decreased 20.74ml, maximum flow rate increased 3.76 ml/s, prostate volume grown downwards 6.70cm3 and the quality of life raised apparently(Pall＜0.05 ). Condusion Combinationof epristeride and terazosin for treatment of BPH is safe and effective.

Objective To study the process of foam fractionation of polyphyllin in semi-batch mode. Methods Taking enrichment ratio, recovery rate of polyphyllin, and purity ratio as the performance criteria and using single examining method to examine the operational parameters, i.e. operation mode, air flow rate, initial feed concentration, solution pH value, initial feed height and temperature on separation performance. The optimal conditions of the process were obtained finally. Results The separation performance is good when gas flow rate is 400 mL/min, initial feed concentration (polyphyllins content) is 0.3 mg/mL, pH value is 7, feed height is 30 cm, and feed temperature is 40 ℃. The enrichment ratio is 25.7, recovery ratio is 42.1%, and the foam liquids purity of total polyphyllin is 41.4%, which is 4.5 times higher than that in feed purity. Conclusion Foam fractionation technique could be applied to separate polyphyllin.

Objective To investigate the levels of pro-inflammatory cytokine interferon (IFN)-γand anti-inflammatory cytokine interlenkin (IL)-10 in expressed prostatic secretions (EPS) of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and their clinical significance. Methods The levels of IFN-γ and IL-10 in EPS of 20 patients with CP (type Ⅲ A, group A ), 20 patients with CPPS (type Ⅲ B,group B) and 10 healthy men (control group) were measured using enzyme-linked immunosorbent assay (ELISA). The results were analyzed comparatively with NIH-chronic prostatitis symptom index (NIH-CPSI).Results The levels of IFN-γ in EPS of group A and group B were ( 14.92 ± 7.85 ), ( 13.74 ± 5.96) ng/L respectively, which were higher than that in control group [(7.47 ± 1.40) ng/L] (P ＜ 0.05 ). And the levels of IL-10 in EPS of group A and group B were (216.40 ± 33.65 ), (223.70 ± 45.21 ) ng/L respectively, which were higher than that in control group [( 162.10 ± 43.81 ) ng/L] ( P ＜ 0.05 ). There was no statistically significant difference between group A and group B. No correlation between NIH-CPSI and IFN- γ,IL-10 levels in EPS(P ＞ 0.05 ). Conclusion IFN-γ and IL-10 have a very important role in etiology of CP/CPPS and they can be the objective parameters in the diagnosis of CP/CPPS.

AIM: To observe the inhibition of c-Met inhibitor on proliferation of lens epithelial cells (LECs).METHODS: Human's LECs were cultured and hepatocyte growth factor (HGF) and K252a were added to second passage of cells supplied with Dulbecco's modified eagle's medium (DMEM). MTT assay was used to examine the proliferation of LECs, and Western-blot was used to detect the expression change of Bcl-2 and Caspase-3.RESULTS: The photodensity (A) of HGF (50nmol/L) + K252a (30nmol/L) was not significantly different from that of DMEM control (P＞0.05). The expression of Bcl-2 and Caspase-3 were not significantly different from that in the control group.CONCLUSION: K252a, the inhibitor of c-Met, can effectively inhibit the proliferation of LECs.

Background and purpose:Thalidomide can enhance the radiation sensitivity on tumor effectively, but the mechanism of radiosensitization is still unclear. The present study aimed to investigate whether thalidomide could enhance the radiation sensitivity on colon cancer transplanted tumor of mouse, and to investigate the underlying mechanism. Methods: We established the model of colon26 colonic carcinoma, and the mice were divided into 4 groups:Control group, the thalidomide group, the radiotherapy group and thalidomide+radiotherapy group. From the day of treatment, tumors were measured every other day. Then, the xenograft tumor growth curve was depicted. Tumor volumes were measured in different treatment groups, then, the inhibitory rates of tumor growth were calcutated. Using immunohistochemical method in to detect the expression of microvessel density (MVD) in tumor tissue. Results:The mean tumor volumes at day 22 were (4.97±1.20)cm3 (control group), (2.90±0.92)cm3 (T group), (2.66±0.88)cm3 (R group), and (1.89±0.76)cm3 (T+R group). The tumor inhibition rate in the combination group (61.9%) was signiifcantly higher than the other groups (41.7%, 46.5%, P<0.05). The radiotherapy sensitization enhancement ratio of the combined treatment group was 2.27 times than in the radiotherapy group. Thalidomide combined with radiation therapy can significantly inhibit microvessel density of tumor:The decreasing MVD of T+R group, T group and R group were respectively 46.8%, 40.7%and 37.7%, and there was statistical significance between T+R group and T group (P<0.05 ), so as between T+R group and R group. It could be found more necrotic cells in tumor of group, and there was statistical signiifcance between T+R group and control group (P<0.05). Conclusion:Thalidomide can enhance the radiosensitivity mice of colonic carcinoma, and its mechanism may be related to the inhibition of tumor angiogenesis related.
