Objective To study the effect of sodium hyaluronate(SH) on cornea preservation to provide a basis for eyes banks cornea preservation. Methods SH was applied in the short-term and middle-term cornea preservation. The preservation effect was evaluated by corneal morphology, trypan blue-alizarin red staining, activity assay of SDH and G-6-P enzymes, and ultrastructural observation of corneal endothelium. Results The above indices were obviously better in the experiment group than in the control group (P

Objective To establish a HPLC method for the determination of chlorogenic acid, baicaliin, forsythin and wogonin in Shuanghuanglian oral liquid. Methods The column was VP-ODS C18 (250 mm?4.6 mm, 5 ?m). The mobile phase consisted of acetonitrile-0.2% phosphoric acid with gradient elution. The flow rate was 1.0 mL/min and the detection wavelength was at 278 nm. Results The calibration curves were linear within the range of 0.44～6.60 ?g (r=0.999 1) for chlorogenic acid, 0.52～6.18 ?g (r=0.999 1) for baicaliin, 0.20～2.04 ?g (r =0.999 3) for forsythin (r =0.999 3) and 0.13～1.76 ?g (r =0.999 1) for wogonin, respectively. The average recovery of them were 97.0% (RSD=1.1%), 98.98% (RSD=1.1%), 103.55% (RSD = 1.1%) and 96.49% (RSD = 1.1%), respectively. Conclusion The method is simple, practicable, accurate and rapid. It can be applied to content determination of chlorogenic acid, baicaliin, forsythin and wogonin in Shuanghuanglian oral liquid.

Objective To investigate the role of Twist and vascular endothelial growth factor (VEGF)in the development of epithelial ovarian cancer and their relationship with clinical pathological features.Methods The expressions of Twist and VEGF were detected by immunohistochemical staining (SP)method in 80 cases of epithelial ovarian cancer and 10 paired cases of normal ovarian tissue.Results In the 80 cases of ovarian cancer tissues,the positive expression rate of Twist and VEGF in epithelial ovarian cancer was 85% and 86.25%,respectively,which were remarkably higher than those in normal ovarian tissues (P <0.01).The expressions of Twist and VEGF were closely associated with clinical stages,pathological grades and lymph node metastasis,but not correlated with age or pathological patterns (P >0.05).There was a significant correlation between the expressions of Twist and VEGF in epithelial ovarian cancer (r =0.646,P <0.01).Conclusion The high expressions of Twist and VEGF may play a potential role in the occurrence,development and invasion process of epithelial ovarian cancer.

Objective To assess the diagnostic value of bone scanning and bone alkaline phosphatase (B-ALP) detection in diagnosis of osseous metastases in lung cancer. Methods 58 patients with lung cancer were examined by bone scanning and serum alkaline phosphates(ALP) and B-ALP detection. The results were analyzed. Results Among the 58 patients, bone scanning found osseous metastases in 33 patients, the incidence was 56.90 %. Among the 58 patients, the incidence of bone metastasis of adenocarcinoma was 70.97 % (22/33) and squamous carcinoma was 42.86 % (9/21) (x2 =4.109, P =0.0427). The incidence of bone metastases increased in B-ALP ≥150 U/L. B-ALP was significantly correlated with the number of metastatic loci in bone. The sensitivity of bone scanning is the highest (93.94 %), but specificity the lowest (92.00 %).The sensitivity combining bone scanning and B-ALP is the lowest (57.58 %), but the specificity the highest (100.00 %). Conclusion Whole-body bone scanning has high sensitivity in early detection of bone metastases. For diagnosis of osseous metastases in patients with lung cancer, bone scanning is the primary choice. Combining the bone scanning with B-ALP can increase specificity. B-ALP has certain using value to confirm bone metastasis and decide the disease extent.

Objective To study the inhibitory effects of total flavonoids of scutellaria baicalensis georgi(TFSB) on S180,Hep-A-22 and Bcap-37 tumor cell proliferation in vitro and on S180,Hep-A-22 in mice bearing tumor in vivo.Methods In vitro,S180,Hep-A-22 and Bcap-37 cells were divided into control group and TFSB groups(12.5,25.0,50.0,100.0 mg?L-1).The inhibitory effects of TFSB on proliferation of S180 and Hep-A-22 were measured by XTT colorimetric assay,and Bcap-37 cells were measured by MTT colorimetric assay.In vivo,the mice bearing tumor were divided into control group,CTX group(30 mg?kg-1),high,middle,low doses TFSB groups(200,100,50 mg?kg-1).After the mice bearing S180 and Hep-A-22 tumor cells were treated with TFSB for 15 d,the tumor weights were measured,the inhibitory rates of S180 and Hep-A-22 were calculated and survival of Hep-A22 was measured after administration of TFSB for 10 d.Results TFSB inhibited the proliferation of S180,Hep-A-22 and Bcap-37 cells,IC50 values were 16.04,17.74 and 9.05 mg?L-1,respectively.The tumor weight of mice bearing S180 and Hep-A-22 cells in TFSB groups(200,100,50mg?kg-1) were lowered than that in control(P
