  • Association between Expression of Osteopontin and Chinese Population with Hepatocellular Carcinoma and Its Clinical Pathological Characteristics: A Meta-Analysis

    ObjectiveTo systematically review the association between expression of osteopontin (OPN) and Chinese population with hepatocellular carcinoma (HCC) and its clinical pathological characteristics. MethodsSuch databases including CBM, CNKI, VIP and WanFang Data were searched from inception to July 2014, for studies about the association between expression of OPN and Chinese population with HCC and its clinical pathological characteristics. Two reviewers independently screened literature according to the exclusion and inclusion criteria, extracted data, and assessed methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.2 software. ResultsA total of 10 case-control studies (involving 723 HCC cases and 102 controls) were included. The results of meta-analysis showed that:OPN expression was higher in HCC group than normal control group (OR=10.25, 95%CI 6.13 to17.14); and higher in imperfect capsular infiltration group than perfect capsular infiltration group (OR=2.71, 95%CI 1.58 to 4.64). However, no significant difference was found in OPN expression between isolated tumour group and multiple tumours group (OR=0.95, 95%CI 0.56 to 1.62); between high differentiation group and low differentiation group (OR=0.60, 95%CI 0.36 to 1.01); and between clinical stages I-Ⅱ group and clinical stages Ⅲ-IV group (OR=0.93, 95%CI 0.53 to 1.63). ConclusionCurrent evidence shows that OPN may take part in the whole course (occurrence and advance) of HCC in Chinese population, but the problem whether it can be used as a factor to evaluate prognosis needs to be further studied.

  • Application of Vacuum-assisted Closure in the Treatment of Venous Ulcer of Lower Extremities

    ObjectiveTo analyze the clinical effect of vacuum-assisted closure in treating venous ulcer. MethodsThirty seven patients including 21 males and 16 females with lower extremity venous ulcer treated in our hospital from January 2013 to January 2014 were included in our study. Based on random number table, the patients were divided into treatment group [n=19, (66.47±6.22) years old] and control group [n=18, (66.39±5.37) years old]. The treatment group received vacuum-assisted closure, while the control group underwent routine moist therapy. Wound healing and visual analogue pain scores were observed. Chi-square test and t-test were used for statistical analysis. ResultsWound healing rate was 84.2% in the treatment group and 55.6% in the control group, and the difference between the two groups was statistically significant (χ2=26.66, P<0.05). Wound healing time was (13.84±3.13) days in the treatment group and (27.35±1.73) days in the control group, and the difference was statistically significant (t=-7.498, P<0.01). Visual analogue pain scores in the treatment group was 3.53±0.51, and in the control group, it was 4.41±0.51, and the difference was statistically significant (t=-5.197, P<0.01). ConclusionVacuum-assisted closure can significantly improve wound healing and alleviate sufferings in the treatment of venous ulcer.
