Objective To optimize the treatment of chronic hepatitis C recurrence.Methods During May 2008 to May 2012, 50 patients with chronic recurrent hepatitis C were chosen in the infectious department of our hospital.They were divided into two groups with 25 cases in each group.Group A was treated by standard extended treatment scheme,while Group B was treated by standard large dose scheme.The effect was estimated by the observation of sustained virologic response in the two groups (sus-tained virologic response,SVR).Results 32% SVR rate was found in group A and 23% SVR rate was found in Group B.38% re-currence rate appeared in group A after six months and 43% recurrence rate occurred in group B,there were significant difference between two groups(P <0.05).Conclusion The standard extended treatment schemes of pegylated interferon and ribavirin is su-perior to group B in SVR rate.

Objective To evaluate the apphcation of wireless mobile infusion system in the outpatients and emergency patients.Methods A total of 566 outpatients and emergency patients with infusion were divided into the observation group and the control group according to the order of infusion.The observation group with 297 cases was used wireless mobile infusion system,and the control group with 269 cases was used traditional infusion method.The reception time,infusion waiting time and satisfaction for nurses' job of patients between two groups were compared.The satisfaction for job of nurses among different work models were compared,too.Results The reception time,infusion waiting time of patients in the observation group were less than those in the control group:(2.07±0.26) min vs.(3.17±0.26) min,(9.89±0.31) min vs.(13.49± 0.21) min,and there were significant differences,P＜0.01.The satisfaction for nurses' job of patients in the observation group were better than those in the control group,x2=8.921,7.064,5.251,and there were significant differencs,P＜0.05.The satisfaction for job of nurses in the observation group was better than that in the control group,and there was significant difference,P＜0.05.Conclusion Wireless mobile infusion system can improve work efficiency,guarantee the safety of infusion,improve patients and nurses' satisfaction.

OBJECTIVETo investigate the effect of photodynamic therapy combined with compound betamethasone in the treatment of hypertrophic scar.

METHODS37 cases of keloid were divided into two groups, 19 cases in the treatment group, 18 cases in the control group. The patients in treatment group were treated with photodynamic therapy combined with compound betamethasone injection therapy. The patients in the control group were treated by compound betamethasone injection. The effect and recurrence rate were compared before and after treatment.

RESULTSThe effective rate was 89.5% in the treatment group, 55. 6% in the control group, showing significant difference between the two groups (P = 0.029) The relapse rate in treatment group was significantly lower than that in the control group (P = 0.047) CONCLUSIONS: Photodynamic therapy combined with compound betamethasone has good effect and safety for the treatment of hypertrophic scar. The combined treatment can reduce the treatment period and side effects

Objective To select microRNAs (miRNA) associated with human cutaneous malignant melanoma (MM). Methods Total RNA was extracted from 6 tissue samples of MM and 9 human control samples of pigmented nevi, and small RNAs of less than 200 bp were enriched, miRNA microarray was used to select differentially expressed miRNAs between tissue samples of MM and pigmented nevi from 468 candi-dates. The expression of differentially expressed miRNAs was confirmed by fluorescence based real-time quan-titative PCR (qPCR) in all of these samples. Those miRNAs that were identified as differentially expressed with both miRNA microarray and qPCR were considered as significant miRNAs. Results Between the tissue samples of MM and pigmented nevi, 12.18% to 86.33% of miRNAs differentially expressed by more than 2 folds, 1.28% to 19.02% by more than 5 folds, and 0.43% to 5.34% by more than 10 folds. The expression of miRNA-21 was obviously up-regulated, while that of miRNA-320 and miRNA-494 was down-regulated in the MM samples. Conclusion There is an increase in the expression of homo sapiens miRNA-21 but a decrease in that of miRNA-320 and miRNA-494 in MM tissues.

Objective To investigate the effect of postconditioning with propofol and ischemia on the hepatic ischemia-reperfusion (I/R) injury in rats. Methods Thirty male SD rats weighing 200-250 g were randomly divided into 5 groups of 6 animals each: group I sham operation (group S); groupⅡ I/R; group Ⅲ ischemic postconditioning (group IPC); group Ⅳ propofol postconditioning (group PPC) and group V IPC + PPC. In group Ⅱ-Ⅳ the hepatic arteries and veins of middle and left lobes were occluded for 1 h followed by 4 h reperfusion. Ischemia of the liver was confirmed by the color of the liver turning from red to gray. In group Ⅲ and Ⅴ the livers were subjected to six episodes of 10 s ischemia at 10 s intervals at the end of 1 h ischemia before 4 h reperfusion. In group Ⅳ and V 0.5 % propofol 10 mg/kg was given iv at the end of ischemia followed by propofol infusion at 40 mg·g~(-1) ·h~(-1). Blood samples were taken at the end of 4 h reperfusion for determination of serum ALT activity. Mean-while liver specimens were taken for electron microscopic examination and determination of MDA content and SOD activity. Results I/R significantly increased serum ALT activity and MDA content in the liver and decreased liver SOD activity in group Ⅱ . The I/R-induced changes were significantly attenuated by propofol and/or ischemic postconditioning in group Ⅲ ,Ⅱ and Ⅴ . I/R significantly increased Bel-2 and Bax protein expression in the liver cells. Propofol and/or ischemic postconditioning increased Bel-2 protein expression further but decreased Bax protein expression in group Ⅲ , Ⅳ and Ⅴ as compared with group Ⅱ (group I/R).Electron microscopic examination showed that the pathologic changes induced by I/R were less severe in group Ⅲ, Ⅳ and Ⅴ than in group I/R. Conclusion Postconditioning with propofol and ischemia can reduce the hepatic I/R injury and the mechanism may be related to inhibition of lipid peroxidation and apoptosis, but the efficacy is the same as that of propofol postconditioning alone.

Objective To study the clinical results and safty of photodynamic therapy (PDT) after single and multi treatments of patients with subfoveal choroidal neovascularization (CNV) caused by wet age related macular degeneration (AMD). Methods From July, 2000 to July, 2001, 20 wet AMD patients (31 eyes) 47 88 years old (mean 68.2 years old) with best corrected visual acuity from FC/10 cm to 0.6 diagnosed through optic coherence tomography (OCT), fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were treated with PDT. All cases were assigned to benzoporphyrin derivative mono acid (BPD) (6 mg per square meter of body surface area), administered via intravenous infusion of 30 ml over 10 minutes. Fifteen minutes after the start of the infusion, a laser light at 689 nm (Zeiss company, German) delivered 50 J/cm 2 at an intensity of 600 mW/cm 2 over 83 seconds on CNV. Visual acuity, photochrome of ocular fundus, OCT, FFA, ICGA were used to evaluate the effects of photodynamic therapy with BPD. Follow up of these patients was planned 1 2 week and every 3 month after PDT. Once the lesion area progressed, PDT was applied again. Tweenty cases (31 eyes) were followed up from 3 to 18 months (average 12 month).In 1 affected eye, PDT was applied fow 4 times, 4 eye for 2 times, and the other 26 eyes for 1 time. Results The visual acuity in 13 (41 9%) eyes was improved ( increase≥2 lines) after PDT. Stabilized (?1 line) in 17 (54 8%) eyes and decreased 2 lines (attributed to the recur of CNV ) in 1 (3 2%) eye. After PDT, the fundus haemorrhage and fluid leakage reduced. FFA and ICGA showed. cessation and obvious reduction of fluorescein leakage from CNV in all patients 2 weeks after photodynamic therapy, and retreatment decreased the leakage step by step. Fluorescein leakage from at least a portion of the CNV reappeared by 1 3 month after treatment in some cases. OCT also showed the reduction of the size of CNV, moreover, the edema of surrounding retina and choriodal and serous neural epithelial detachment recovered obviously. No side affect during and after PDT was noticed. Conclusions PDT with BPD can achieve short term effect on part or total cessation of fluorescein leakage from CNV without loss of vision or growth of classic CNV in patients with age related macular degeneration, retreatment of PDT was also effective.
