OBJECTIVETo investigate the optimal operation method for the management of various chronic wounds in legs and feet.

METHODSFifty-one chronic wounds were evaluated according to infection, inflammatory response, and distribution in different areas of the leg and foot. Preoperative treatment was given accordingly, then transposition of skin flap, skin grafting, or amputation was performed. The healing rate after single session operation and average hospitalization were statistically analyzed.

RESULTSThe wound healing rate after single session operation was 86. 3% , the average hospital stay was (17. 8 +/- 2. 1) days, and the appearance and function of the leg and foot after operation was satisfactory.

CONCLUSIONThe appropriate preoperative treatment and operation method conforming to the wound location and evaluation are of vital importance in the management of chronic wounds in the leg and foot. Operation is one of the most effective ways to repair chronic wounds in the leg and foot, and it can shorten the wound healing process and restore the function.

OBJECTIVECongenital arteriovenous malformations(AVM) are considered to be the most difficult and challenging problems in the treatment of hemangiomas and vascular lesions. This study focused on the natural history, the clinical classification, the choice and effectiveness of various treatments.

METHODSThis retrospective review included 83 patients with extracranial arteriovenous malformations, who were referred to our department over the past 6 years. The anatomic patterns, clinical staging, respective treatments, influential factors of endovascular treatment, causes of recurrence were analyzed.

RESULTSAccording to clinical manifestations, arteriovenous malformations were categorized as three clinical stages: the quiescence, the expansion and the decompensation stages. Most AVMS in the quiescence stage only require endovascular treatment while those in the decompensation stage require surgical resection. Angiography was performed not only for diagnosis of AVM but also as an initial therapeutic step in the form of embolization, which might be the only means to some AVM without surgical possibility or necessity.

CONCLUSIONThe new concept of staging and management is expected to be helpful for diagnosis and treatments of AVM.

AIM:To investigate the role of SDF-1α/CXCR4 axis in pancreatic cancer cell migration and invasion.METHODS:The mRNA expression of CXCR4 in 4 pancreatic cancer cell lines was detected by RT-qPCR.The migration and invasion abilities of PANC-1 cells with the axis activated by exogenous SDF-1αor inhibited by CXCR4 inhibitor AMD3100 were detected by Transwell assays.The cell viability was measured by MTS assay.The protein expression of the epithelial-mesenchymal transition (EMT) -related molecules in the cells treated with exogenous SDF-1αor AMD3100 was determined by Western blot.RESULTS:All of the 4 pancreatic cancer cell lines expressed CXCR4 mRNA, while the PANC-1 cell line expressed the most.Exogenous SDF-1αpromoted the migration and invasion abilities of PANC-1 cells, which was inhibited by AMD3100.The PANC-1 cells treated with exogenous SDF-1αfor 72 h grew faster, while SDF-1αcombined with AMD3100 made little significance to the viability of PANC-1 cells.Exogenous SDF-1αinduced EMT of PANC-1 cells by up-regulating the expression of SNAIL and TWIST, and AMD3100 reversed this effect.CONCLUSION:SDF-1α/CXCR4 axis enhances the migration and invasion abilities of pancreatic cancer cells through inducing EMT.

AIM:To investigate the protective effect of basic fibroblast growth factor(bFGF)on the heart of mice with myocardial infarction and its mechanism.METHODS:The model of myocardial infarction was established by the ligation of left anterior descending artery of C57/B6 mice(8～12 weeks old)after lateral thoracotomy.The mice were divided into sham operation group ,myocardial infarction group and bFGF administration group.bFGF at 0.5μg was intra-peritoneally injected on alternate days after myocardial infarction for 7 d.Cardiac Doppler ultrasonography was used to de-tect cardiac function after myocardial infarction for 28 d,and left ventricular end-diastolic diameter ,left ventricular end-systolic diameter,left ventricular ejection fraction and left ventricular shortening fraction(LVFS)were used to evaluate cardiac function.After myocardial infarction for 28 d,the mice were sacrificed and the hearts were collected for preparing pathological sections.The degrees of myocardial fibrosis and angiogenesis in the myocardial infarction area were observed. Western blot was used to detect the indicators of angiogenesis.RESULTS:The results of Masson staining showed that bF-GF administration significantly reduced myocardial fibrosis at 28 d after myocardial infarction.Cardiac ultrasound data showed that cardiac functions in myocardial infarction group were poorer than those in sham group ,and bFGF administration significantly improved cardiac functions.Immunofluorescence staining showed that neovascularization in myocardial infarc -tion area of bFGF administration group was more than that in myocardial infarction group.The results of Western blot showed that bFGF activated AKT/HIF-1α/VEGF signaling pathway.CONCLUSION:Intraperitoneal injection of bFGF reduces myocardial fibrosis and improves cardiac function in myocardial infarction mice.bFGF may promote angiogenesis by activating AKT/HIF-1α/VEGF signaling pathway.

Objective To analyze the depression status and its associated factors of residents in Anting Town of Shanghai.Methods By adopting a multi-stage random sampling method, 2 500 people were selected from among the residents in Anting Town.Questionnaires were independently completed by the residents surveyed and a total of 2 498 valid questionnaires were collected.The depression module for Patient Health Questionnaire (PHQ-9) was used to evaluate depression symptoms.Univariate and multivariate logistic regression analyses were used to analyze the depression status and its associated factors.Results The detection rate of depression symptoms was 4.60% and the main symptom was light depression.Lack of vitality, eating disorders, sleep disorders and loss of enjoyment were among the most frequently-selected items in the univariate evaluation for the depression status.The results of univariate analyses indicated that age, educational level, marital status, self-evaluated health status and average(per person) family monthly income were the factors associated with the depression status.The results of multivariateanalyses indicated that self-evaluated health status and average(per person) family monthly income were the main associated factors.Conclusion The prevalence of depression status for the residents in Anting Town is relatively low.Emphases should be focused on the residents with poor health condition and with the average(per person) family monthly income below 2 000 RMB yuan.

OBJECTIVETo analyze and evaluate the efficacy and safety of tacrolimus and low-dose steroids in the treatment of steroid-resistant nephrotic syndrome in children.

METHODTwenty-one children with steroid-resistant nephrotic syndrome enrolled from October 2008 to July 2010 into this retrospective longitudinal study received oral tacrolimus treatment, 0.1 to 0.15 mg/kg per day and once every 12 hours, and prednisone 0.2 to 0.75 mg/kg per day simultaneously. During the treatment, the plasma concentration of tacrolimus, urine volume, urine, serum creatinine and liver function were regularly monitored.

RESULTAfter 1 to 3 months treatment, 14 cases showed complete remission and 7 cases had partial remission. Sixteen patients received renal biopsy, of whom 6 revealed minimal change nephropathy with complete remission in 3 cases, 3 cases had partial remission;4 cases revealed focal segmental glomerulosclerosis with 2 complete remission and 2 partial remission; other 5 children with IgM nephropathy and 1 mesangial proliferative glomerulonephritis achieved complete remission. Within treatment period, 6 patients presented transient adverse reactions, without altering the principle treatment strategy, but only taking the symptomatic treatment. During follow-up, 1 case was lost to follow-up and the remaining 20 cases were followed up from 2 months to 21 months. In 4 patients the disease relapsed within 1st-year follow-up, while at 2nd-year follow-up, 4 cases had (6 times) recurrence.

CONCLUSIONTacrolimus showed a reliable effect in children with steroid-resistant nephrotic syndrome. Less adverse reactions were seen, and most of them could be tolerated. Nevertheless, the patients had a higher relapse rate after 1 to 2 years treatment. Therefore, the long-term effects of tacrolimus for steroid-resistant nephrotic syndrome remains to be further evaluated.

OBJECTIVETo evaluate the efficacy and safety of entecavir maleate (ETV) versus ETV in Chinese patients with hepatitis B e antigen(HBeAg)-positive chronic hepatitis B(CHB).

METHODSThe patient population of this previously published randomized, double-blind, double-dummy, controlled, multicenter study was expanded by patients in the 0.5 mg/day ETV maleate group (total n = 110) and patients in the 0.5 mg/day ETV group (total n = 108). At treatment weeks 12, 24 and 48, hepatitis B virus (HBV) DNA levels were measured by the Roche Cobas Ampliprep/Cobas Taqman PCR assay. Adverse events (AE) were recorded.

RESULTSAs in the original analysis, the two treatment groups showed similar characteristics at baseline. In addition, the results for the all therapeutic effects showed identical trends to the results obtained in the original analysis, including the statistically similar effects of ETV and ETV maleate treatment-induced decreases in mean HBV DNA level at weeks 12, 24, and 48 (ETV: by 4.28, 5.00, and 5.53 log10 IU/ml vs. ETV maleate: by 4.46, 4.99, and 5.51 log10 IU/ml, respectively; all vs. baseline P more than 0.05), achievement of undetectable levels of serum HBV DNA ( less than 20 IU/ml) at week 48 (ETV: 38.18% vs. ETV maleate: 35.19%; P more than 0.05), HBeAg loss rates at week 48 (ETV: 10.91% vs. ETV maleate: 12.96%; P more than 0.05), HBeAg seroconversion rates at week 48 (ETV: 7.77% vs. ETV maleate: 10.38%; P more than 0.05), normalization of alanine aminotransferase at week 48 (ETV: 75.47% vs. ETV maleate: 82.86%; P more than 0.05), and overall incidence of AE (ETV: 18.02% vs. ETV maleate: 17.43%; P more than 0.05).

CONCLUSIONPerforming analysis of the therapeutic efficacies of entecavir maleate versus entecavir with a larger study population confirmed our original findings of similar efficacy and safety profiles for these two drugs in patients with HBeAg-positive CHB.
