ObjectiveTo evaluate the effect of microwave tissue coagulation (MTC) to treat verruca vulgaris. MethodsWe observed the lesion healing, post- operation infection and scar forma- tion of verruca vulgaris 182 patients in who received MTC treatment. ResultsThe one - operation cure rate was 87.75 ％. The post - operation infection rate was 2.90 ％. The healing time varied from 1 to 8 weeks according to the different lesion location. No obvious scar was observed except 2 patients. ConclusionMTC is a convenient, effective and safe method of treatment for verruca vulgaris.

Objective To discuss the effica of central venous catheter drainage in interventional treatment of abdominal surgical complications.Methods The clinical data of 72 cases of abdominal surgical diseases were retrospectively analyzed,the complications included 23 cases of ascites,19 cases of bile leakage,8 cases of pancreatic fistula,7 cases of pancreatic necrosis and 15 cases of abdominal abscess,they all underwent percutaneous central venous catheter drainage under the guidance of ultrasound or CT.Results Central venous catheter was placed in 72 cases successfully in one time,the cathetem were kept for 2 to 37 days,5 discharged cases with catheter underwent regular reexamination in the clinic.3 cases of ascites were replaced for catheter shedding; 17 cases for occlusion recieved catheter irrigation and guidewire dredging;2 cases of pancreatic necrosis and 1 case of peripancreatic abscess were cured by repeated puncture and replacement of large-bore catheter.2 cases of pancreatic necrosis,1 case of pancreatic fistula and 1 case of appendicitis underwent laparotomy finally; 1 case of postcholecystectomy bile leakage underwent endoscopic stent therapy; 1 cases of severe pancreatitis complicated with ARDS was treated in ICU.Conclusion Central venous catheter drainage guided by ultrasound or CT for treatment of abdominal surgical complications was not only safe but also effective,and is worthy of popularization and application.

OBJECTIVETo investigate the apoptosis-inducing effect of DMF on the human liver cells (HL-7702) in vitro.

METHODSLiver cells were exposed to different concentrations of DMF (0, 50, 100, 150, 200 mmol/L) for 12 hours. Apoptotic rate, the expression of Bax, Bcl-2 and Caspase-3 in liver cells were measured by FCM and western blotting respectively.

RESULTSThe increase in apoptotic rate of hepatocytes in concentration-manner was shown after DMF treatment for 12 h. After treatment the expression of Bcl-2 was decreased steadily and lower than the control group (P < 0.01), the expression of Bax showed no significant difference among the groups of different dosage by one-factor analysis of variance (P > 0.05), as the increase of the dosage of DMF. The ratio of Bcl-2/Bax dropped with the dosage of DMF increasing, and the ratio in 200 mmol/L of DMF was significantly lower than that of the control (P < 0.01). The new lands of procaspase-3 in 150, 200 mmol/L were observed, which demonstrated that there was active caspase-3.

CONCLUSIONDMF can induce apoptosis of cultured adult normal hepatocytes in vitro, and the mechanism might be related to the decrease of Bcl-2/Bax and the cleavage of Caspase-3.

Objective: To analyze the CYP2C19 gene polymorphism in patients with upper digestive system diseases in Anhui Province, so as to provide evidence for individual treatment. Methods: The 307 patients with upper digestive system diseases in the Department of Gastroenterology, The 901st Hospital of Combined Service Force of People＇s Liberation Army were selected. The CYP2C19 genotypes were detected by DNA microarray microarray. The CYP2C19 genotypes and metabolic types in different genders, ages and diseases were analyzed. Results: There were 197 males ( 64.17% ) and 110 females ( 35.83% ) , with the age of ( 58.00±16.13 ) years old. The gene frequency of CYP2C19*1, CYP2C19*2 and CYP2C19*3 was 62.70%, 32.25% and 5.05%, respectively. There were 119 cases (38.76%) of *1/*1 ( 636GG, 681GG ), 129 cases ( 42.02% ) of *1/*2 ( 636GG, 681GA ) , 18 cases (5.86%) of *1/*3 ( 636GA, 681GG ) , 29 cases ( 9.45% ) of *2/*2 ( 636GG, 681AA ) , 11 cases ( 3.58% ) of *2/*3 ( 636GA, 681GA ) , and 1 cases ( 0.33% ) of *3/*3 ( 636AA, 681GG ). In terms of metabolisms, there were 119 cases ( 38.76% ) of fast metabolism type, 147 cases (47.88%) of intermediate metabolism type and 41 cases (13.35%) of slow metabolism type. There were no significant differences in CYP2C19 genotypes and metabolic types among the patients with different gender, age and digestive system diseases ( P＞0.05 ). Conclusion The CYP2C19 genotypes of patients with upper digestive system diseases were polymorphic, mainly the fast metabolism type and the intermediate metabolism type, which could provide reference for the clinical medication of individualized treatment of proton pump inhibitors.

Background The hyperplasia of human Tenon capsule fibroblasts (HTFs) is a common cause of filtering surgery failure in glaucomous eye.Researches demonstrated that hydroxycamptothecin is a cell cycle arresting drug and induce apoptosis of cancer and fibroblasts.However,its mechanism is currently less understood.Objective This study was to investigate whether hydroxycamptothecin induce the apoptosis of HTFs and explore the possible mechanism.Methods Human Tenon capsule tissue was obtained from EyeBank of Jiangsu Province Hospital.HTFs were cultured using explant method in vivo and passaged in DMEM containing 10％ FBS.The cells were identified using vimentin and keratin by immunochemistry,and the cells of generation 3-6 in the logarithmic growth phase were used in the experiment.The cells were incubated with 0.01,0.05 or 0.10 g/L hydroxycamptothecin for 5 minutes respectively,and the cells without any hydroxycamptothecin were served as the control group.Cell viability then was assessed by cell counting kit-8 (CCK8) for the optimal inhibition concentration.The cells were treated by 0.10 g/L hydroxycamptothecin for 24 hours,and the apoptotic rate of the cells were assayed with annexin V/PI double-staining.Mitochondrial membrane potential of HTFs was assessed using JC-1 staining.The expressions of caspase-3,caspase-9 and cytochrome C (cyt C) in mitochondria and cytoplasm of HTFs were detected by Western blot.Results The proliferative value (A450) of the HTFs 0,0.01,0.05,0.10 g/L was 0.9716±0.0608,0.8035 ± 0.0346,0.7048 ±0.0446,0.6265 ±0.0286,with a significant difference (F =26.372,P =0.002).A450 of HTFs in the 0.01,0.05,0.10 g/L groups was significantly lower than the control group (P＜0.05),with the lowest A450 value in the 0.10 g/L group.The apoptotic percentage of HTFs was (18.72±1.41)％,in the 0.10 g/L hydroxycamptothecin group and that of the control group was (3.67 ±0.36)％,showing a significant difference between them (t =-10.374,P=0.001).The expression intensity of caspase-3 and caspase-9 protein in HTFs was higher in the 0.10 g/L hydroxycamptothecin group than that in the control group.JC-1 staining showed that the green fluorescence of the monomer JC-1 in cytoplasm was stronger in the 0.10 g/L hydroxycamptothecin group than that in the control group,but the red fluorescence of the polymer JC-1 in the 0.10 g/L hydroxycamptothecin group was weaker than that in the control group.The grey scale of cyt C protein in HTFs in mitochondrion was 0.0605±0.0022 in the 0.10 g/L hydroxycamptothecin group,showing a significant increase in comparison with 0.0301 ±0.0016 of the control group (t=4.865,P=0.014).However,the grey scale of cyt C protein in cytoplasm was declined in the 0.10 g/L hydroxycamptothecin group than that in the control group (0.0605 ±0.0022 vs.0.0301 ±0.0016) (t =-11.177,P =0.001).Conclusions Hydroxycamptothecin can induce the apoptosis of HTFs through activating the mitochondrial apoptosis pathway.
