BACKGROUND:Studies have found that a variety of biological materials can be used for preparing corneal stroma scaffolds that have good biocompatibility, but research on preparation and biocompatibility of the acel ular porcine corneal stroma scaffold is little. OBJECTIVE:To explore the preparation and biocompatibility of the acel ular porcine corneal stroma scaffold. METHODS:Acel ular porcine corneal stroma scaffold and its extract were prepared. Wel-grown human corneal stromal cel s were selected and cultured in the extract of acel ular porcine corneal stroma scaffold (experimental group) or in the complete medium (control group), respectively. After 1, 2 and 3 days of culture, the proliferation ability of human corneal stromal cel s was detected by MTT assay. In the meanwhile, human corneal cel s were directly seeded onto the acel ular porcine corneal stroma scaffold, and then the cel growth on the scaffold was detected using immunochemical method. RESULTS AND CONCLUSION:The number of human corneal stromal cel s was in a rise with time in the two groups, and absorbance values had no significant difference between two groups at different time points of culture. Human corneal stromal cel s grew wel on the scaffold, and were positive for cel integrinβ1, vimentin, aldehyde dehydrogenase 3A1, as wel as CD34, CDK2 and K-Ras. These results show that the acel ular porcine corneal stroma scaffold has no cytotoxicity, and has good biocompatibility.

Objective To study the effect of UHRF1 expression inhibition by RNA interference on the radiosensitivity of esophageal cancer cell line TE-1 and its mechanism.Methods Short hairpin RNA (shRNA) targeting UHRF1 gene was introduced into TE-1 cells by lentivector-mediated transfer.The cells were divided into three groups:non-transfected group,negative control (NC)-shRNA-transfected group,and UHRF1-shRNA-transfected group.The mRNA and protein expression levels of UHRF1 in TE-1 cells were measured by RT-PCR and Western blot before and after transfection.After transfection and X-ray radiation,the radiosensitivity of TE-1 cells was evaluated by colony formation assay; the cell cycle and cell apoptosis were determined by flow cytometry; the γ-H2AX (as a marker of DNA damage) level was measured by Western blot.Results After transfection with UHRF1-shRNA,the mRNA and protein expression levels of UHRF1 were significantly decreased in TE-1 cells,as compared with those in the NC-shRNA-transfected group and non-transfected group (0.11 vs 0.96 and 0.98,F =124.21,P =0.000;0.10 vs 0.89 and 0.94,F =125.25,P =0.000).The UHRF1-shRNA-transfected group had sensitization enhancement ratios of 1.53 (D0 ratio) and 1.95 (Dq ratio).X-ray radiation could cause G2/M arrest and increase apoptotic rate and γ-H2AX expression in TE-1 cells.Compared with the two control groups,the UHRF1-shRNA-transfected group showed significantly less G2/M arrest (F =500.15,P =0.000),a significantly higher apoptotic rate (F =100.10,P =0.000),and significantly higher residual γ-H2AX expression (F =61.00,P =0.000) at 24 hours after X-ray radiation.Conclusions RNA interference can effectively inhibit the UHRF1 expression and enhance the radiosensitivity of TE-1 cells.The mechanism may be related to cell cycle regulation,cell apoptosis,and DNA damage repair.

OBJECTIVETo observe the clinical effect of chronic fatigue syndrome (CFS) treated with moxibustion at Gaohuang (BL 43).
METHODSWith stratified block randomization, 72 patients accorded with inclusive criteria were divided into a moxibustion at Gaohuang (BL 43) group (moxibustion group) and an acupuncture group, 36 cases in each one. In the moxibustion group, Gaohuang (BL 43) was treated with big moxa cones as the main acupoint, 10 cones a time; Qihai (CV 6) and Zusanli (ST 36) were added with big moxa cones, 7 cones a time. In the acupuncture group, acupoints were the same as those in the moxibustion group, and twirling reinforcing method was used after qi arriving, 60 times one minute and 360° with range. In the two groups, 10-day treatment was made into one course and there were two days between courses. The treatment was given once a day for 3 courses. Changes of fatigue assessment index (FAI) before and after treatment and clinical effects were observed.
RESULTSThe total effective rate was 88.9% (32/36) in the moxibustion group, which was better than 72.2% (26/36) in the acupuncture group apparently (P < 0.05). After treatment in the two groups, FAI scores were obviously declined compared with those before treatment (both P < 0.01) and FAI score in the moxibustion group was apparently lower than that in the acupuncture group (P < 0.05).
CONCLUSIONMoxibustion at Gaohuang (BL 43) can improve the FAI score of patients with CFS and the clinical efficacy is definite.

Objective To explore the effects of Yishen Capsule on the soluble endothelium protein C receptor (sEPCR) and P-selectin (CD62P) as well as the serum levels of immunoglobulin (Ig) and complement 3 (C3) in patients with chronic glomerulonephritis (CGN). Methods The changes of sEPCR and CD62P levels in plasma as well as Ig and C3 levels in serum were assessed in 40 normal subjects and 78 patients before and after treatment by double-antibody enzyme-linked immunosorbent assay, flow cytometry and immunoturbidimetry, respectively. Results Compared with those in normal group before treatment, the levels of sEPCR and CD62P in plasma as well as IgA in serum increased obviously (P<0.01), and the levels of IgG and IgM as well as C3 in serum decreased significantly in CGN patients (P<0.01). After three months' treatment with Yishen Capsule, the levels of sEPCR and CD62P in plasma and IgA in serum decreased significantly (P<0.05 or P<0.01), and the levels of IgG and IgM in plasma as well as C3 in serum increased obviously (P<0.05 or P<0.01). Conclusion The mechanism of Yishen Capsule's effect in treating patients with CGN may be correlated with decreasing sEPCR and CD62P levels in plasma as well as regulating the levels of Ig in serum and C3.

Objective To evaluate the short term results of endovascular laser for the treatment (ELVT) of great saphenous varicosity. Methods Twenty one cases (a total of 27 lower extremities) were enrolled. Treatment included EL combined with ligation and resection of communicating branches. One patient underwent high ligation and resection of the great saphenous vein for the purpose of pathology after ELVT treatment. Result Twenty patients were followed-up for a period of 2~6 months. Color Duplex ultrosonography was conducted 2 weeks,4 weeks,and 6 mos,respectively. Thrombotic obliteration was found in all cases. Pathology study showed perforation of the vein with intimal injury and thrombosis. Conclusion The short term efficacy of EL treatment is definite with insignificant side-effect,and quick patient recovery. The mechanism is related to direct thermal injury of laser to the venous intima resulting in thrombotic obliteration.

Objective To investigate the expression of Kuppel-like factor 2( KLF2 )after focal cerebral ischemia-reperfusion( I/R)injury in rats and the intervention effect of nuclear factor kappa B ( NF-κB)inhibitor. Methods Sixty healthy male SD rats were randomly divided into a sham operation group,an I/R group,and a NF-κB inhibitor group( n=20 in each group). A focal cerebral I/R model was induced by the intraluminal suture method,and NF-κB inhibitor( pyrrolidinedithio carbamate,PDTC)was given to intervene. The observation time points were 6,12,24,and 48 hours after I/R. Reverse transcription-polymerase chain reaction(PCR)and Western blot were used to measure KLF2 mRNA and protein expression in ischemic brain tissue. Enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of serum tumor necrosis factorα( TNF-α),and they were compared among groups. Results Compared with the sham operation group,the expression levels of KLF2 mRNA and protein in I/R group in the ischemic brain tissue at each time point were averagely decreased( the relative expression levels of KLF2 mRNA:0. 46 ± 0. 03 vs. 0. 82 ± 0. 04,0. 30 ± 0. 04 vs. 0. 78 ± 0. 05,0. 18 ± 0. 04 vs. 0. 76 ± 0. 02,0. 26 ± 0. 02 vs. 0. 81 ± 0. 04,respectively;the relative expression levels of KLF2 protein:0. 46 ± 0. 04 vs. 0. 80 ± 0. 02,0. 30 ± 0. 02 vs. 0. 79 ± 0. 02,0. 15 ± 0. 02 vs. 0. 77 ± 0. 01,0. 24 ± 0. 01 vs. 0. 79 ± 0. 02,respectively). They reached the lowest values at 24 hours after I/R,while the serum TNF-αlevels were increased. There were significant differences(all P<0. 05). After giving NF-κB inhibitor PDTC,the expression levels of KLF2 mRNA and protein at 6,12,24,and 48 hours after I/R were upregulated differently compared with the I/R group. The relative expression levels of KLF2 mRNA were 0. 61 ± 0. 04,0. 44 ± 0. 03,0. 34 ± 0. 02,and 0. 43 ± 0. 04, respectively. Those of KLF2 protein were 0. 60 ± 0. 02,0. 43 ± 0. 02,0. 33 ± 0. 01,and 0. 44 ± 0. 03, respectively,while the levels of TNF-αwere decreased. There were significant differences(all P<0. 05). There was a negative correlation between the KLF2 mRNA levels and the serum TNF-αlevels at each time point in the I/R group and the PDTC group( r= —0. 728 ,P<0. 05 ). Conclusions The expression levels of KLF2 mRNA in brain tissue are decreased after I/R,and it is negatively correlated with the serum TNF-α levels. It may be involved in the pathological process of I/R by NF-κB pathway mediated inflammatory reaction.
