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.

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 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 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.

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 Doxycycline is a broad spectrum antibiotic,and it is frequently used in the treatment of ocular surface diseases.Objective The purpose of the present study was to investigate the effect of doxycycline on the inhibition of cell proliferation in bovine corneal myofibroblasts in vitro and assess its contribution to ocular surface repairing mechanism.Methods Six fresh bovine corneas were collected.The corneal stromal layer was isolated by two-step method of 1.0 g/L and 2.0 g/L collegenase-1.Isolated cells were plated at mantaryay culture flask in 10％ FBS of RPMI-1640.Vimentin and alpha-smooth muscle actin (α-SMA) organization were evaluated by immunocytochemistry,and the cells with influoresccence staining for vimentin and α-SMA were identified as the corneal myofibroblasts.Doxycycline at the concentrations of 10,20,40,60,80 mg/L was added to the medium,respectively,in different concentrations of doxycycline groups.Dexamethasone (120 mg/L)was used in the same way in the positive control group,and no drug was used in the negative control group.Cell proliferation was evaluated by MTT and the cell cycle was analyzed by BD FACScan flow cytometer assay 24 hours and 48 hours after addition of any drug.Results The cells grew well and showed the positive response for vimentin and α-SMA.MTT assay showed that the A570values of bovine corneal myofibroblasts were gradually declined with the increase of the concentration of doxycycline and lapse of active time,showing statistically significant difference (Fconcentration =1233.778,P＜0.001 ; Ftime =227.564,P ＜ 0.001).And the difference between the two factors was also statistically significant (Ftime*concentration =51.656,P＜0.001).Flow cytometry cell cycle analysis showed that 24 hours after 10,20,40,60,80 mg/L doxycycline treated,the perentage of of corneal myofibroblast cell in G0-G1 phase was 82.85％,84.36％,85.18％,87.12 ％ and 89.31％,showing significant increase in comparison with 63.89％ of the negative control group (all P＜0.05),and that of 40 mg/L doxycycline group was near the positive control group.Forty-eight hours after 10,20,40,60,80 mg/L doxycycline treated,the perentage of of corneal myofibroblast cell in G0-G1 phase was 82.78％,86.15％,88.23％,89.57％,93.00％,with significant increase in comparison with 70.17％ of the negative control group (all P ＜ 0.01),and that of 40 mg/L doxycycline group was near the positive control group.Conclusions The growth of the bovine corneal myofibroblasts is inhibited by doxycycline in time-and dosedependent manner in the range from 10 mg/L to 80 mg/L,and 40 mg/L of doxycycline has an obviously inhibitory action as 120 mg/L dexamethasone.
