BACKGROUND:The severity of tissue injury varies with the causes of the amputated finger. Simple soft tissue, vessels or nerves injury could be easily repaired by adjacent finger flap or abdominal flaps. However, these treatments are short of long repair time, reoperation and unsatisfactory appearance of the finger. OBJECTIVE:To investigate the efficiency of Flow-through flap from the fibular side of great toe to repair skin and soft tissue defects in digital replantation. METHODS:From January 2011 to October 2013, Flow-through flap from the fibular side of great toe was applied to repair soft tissue injury in digital replantation for 11 cases (8 males and 3 females, age ranged from 23 to 42 years. Skin defects ranged from 2.0 cm ×1.5 cm to 4.0 cm×2.2 cm; vascular defect ranged from 1-3 cm, 1.5 cm averagely; and the flap size ranged from 2.2 cm×1.7 cm to 4.5 cm×2.5 cm. RESULTS AND CONCLUSION:The folow-up time of al patients was 6-18 months. Digital replantation was successful in al the 11 cases. Ten cases were healed by first intention, and one case was gradualy rescued after dressing change. Patients were satisfied with the flap and the peripheral sensation. The peripheral discrimination of patients was 4 to 10 mm. The fingers functioned wel in flexion and extension. Of the 11 cases, 9 cases were valued excelent and 2 cases was rated as good, according to the upper extremity function evaluation standard of the Hand Surgey Branch of Chinese Medical Association. Flow-through flap from the fibular side of great toe is an ideal method to repair skin soft tissue and vascular defects in digital replantation.

Objective To investigate the expression of SOX2,TGF-β1 and Smad3 in gastric cancer and their relationships with clinical pathological characteristics of gastric cancer. Methods Immunohistochemical staining was used to detect the expression of SOX2, TGF-β1 and Smad3 expression and the clinical pathological characteristics of gastric cancer were analyzed. Results Integrated optical density (IOD) values from the positive expression of SOX2, Smad3 in gastric cancer group were all significantly lower than normal gastric tissues (P < 0.05). IOD values from the positive expression of TGF-β1 in gastric cancer group were all significantly higher than normal gastric tissues (P < 0.05). IOD values from the positive expression of TGF-β1 in lower poorly differentiated gastric cancer tissues, with lymph node metastasis and Ⅲ+Ⅳ were all significantly higher (P < 0.05). Higher IOD values from expression of SOX2 and Smad3 were found in high-moderated differentiated gastric cancer tissues, without lymph node metastasis and Ⅰ+Ⅱgastric cancer (P < 0.05). SOX2, TGF-β1 and Smad3 in gastric cancer has nothing to do with age illness and sex (P >0.05). There was positive correlation between SOX2 and Smad3 expression in gastric cancer tissues, and negative correlation between TGF-β1 and Smad3 in gastric cancer. Conclusions Abnormal expression of SOX2, TGF-β1 and Smad3 protein is related to the onset, development and clinicopathologic features of gastric cancer.

Lycii Cortex, a popular herb medicine in traditional Chinese medicine, is used to treat different inflammation-related diseases. The aim of our work is to find the key constituents inhibiting NF-kappaB, a key regulator of inflammation. In the investigations of cell-based in vitro assays of extracts, we found that both ethyl acetate extract and methanol extract of Lycii Cortex inhibited the TNF-alpha-induced activation of NF-kappaB. Through bioassay-guided fractionation, we identified 4 phenolic amides including trans-N-(p-coumaroyl) tyramine (1), trans-N-feruloyltyramine (2), trans-N-caffeoyltyramine (3), and dihydro-N-caffeoyltyramine (4). Four phenolic amides showed differently inhibitory activities on TNF-alpha-induced NF-kappaB activation. Trans-N-caffeoyltyramine (3) was identified as the key component with an IC50 of 18.41 micromol x L(-1). It was suggested that the hydroxyl group at C-3 in trans-N-caffeoyltyramine might be a key binding site and its C-7,8-double bond might play an important role on NF-kappaB inhibitory activities as the link of the conjugation of pi electrons leading to a partial planar conformation. It might be inferred that the biological activity of compound 3 is attributed to the structure of Michael reaction acceptor containing alpha, beta-unsaturated ketones and benzene along with hydroxyl group in o-diphenol.

Objective To observe the expression of HER-2 and TOPO-Ⅱα in ovarian epithelial cancer,analyze the correlation between their expression and provide theoretical basis for clinical diagnosis,prognosis and treatment. Methods Expression levels of HER-2 and TOPO- Ⅱα in 10 normal ovarian tissues,20 benign tumors and 58 cases of ovarian epithelial cancers were detected by immunohistochemical method, and their correlations with pathological features were analyzed. Results The positive expression rate of HER-2 in normal ovarian and benign tumor tissues were significantly lower than ovarian epithelial cancers respectively ( 10. 0% , 15.0% VS 46. 6% ;P < 0. 05 ). The positive expression rate of TOPO- Ⅱα in ovarian epithelial cancers was significantly higher than normal and benign epithelial ovarian tumor tissue (53.4% vs 10. 0%, and 15.0%,Ps < 0. 05 ), but we did not find significant difference in the comparison between normal and benign epithelial ovarian tumor tissue ( Ps > 0. 05 ). The expression of HER-2 and TOPO- Ⅱα were significantly correlated with clinical stages, histological differentiation of tumor cells (Ps < 0. 05 ) ,but there were no correlations between the age or histological type. In ovarian cancer tissues, a positive correlation between the expression of HER-2 and TOPO- Ⅱα was observed ( r = 0. 324, P < 0. 05 ) . Conclusion The overexpression of HER-2 and TOPO- Ⅱαplay an important role in ovarian carcinogenesis and development. The expression of HER-2 is positively correlated with TOPO- Ⅱα in ovarian epithelial cancers. Coexpression of the two moleculars may be involved in the development and progression of ovarian epithelial cancer, which should be further studied.

Objective To investigate the clinical effect of nicorandil for treatment of patients with acute respiratory distress syndrome (ARDS).Methods A prospective randomized controlled trial was conducted. A total of 40 cases of patients with ARDS admitted to Department of Critical Care Medicine of Guizhou Provincial People's Hospital from October 2012 to October 2014 were enrolled, and they were randomly divided into two groups, 20 cases in each group. The two groups were treated with routine western medicine after admission. On this basis, the observation group was given nicorandil 10 mg, while the control group was given warm boiled water 10 mL, through gastric tubes 3 times a day, the therapeutic course being consecutive 5 days in both groups. The length of stay in intensive care unit (ICU), duration of mechanical ventilation after treatment, oxygenation index (OI), alveolo-arterial oxygen partial pressure difference (PA-aO2), positive end-expiratory pressure (PEEP), acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, Glasgow coma score (GCS) before and after treatment, the predicted death rate (PDR) and 28-day mortality were compared between the two groups. The predicitive factors for 28-day mortality were screened by binary logistic analysis.Results The length of stay in ICU and duration of mechanical ventilation of control group were longer than those of observation group, but the difference was not statistically significant [ICU length of stay (day): 14.55±12.71 vs. 9.15±6.00, duration of mechanical ventilation (day): 13.25±12.27 vs. 7.75±5.32, bothP > 0.05]. After treatment, the GCS was higher than that before treatment in control group and observation group (11.95±3.98 vs. 10.75±4.89, 12.95±3.67 vs. 12.20±4.56), while APACHE Ⅱ score, PDR and PEEP were all lower than those before treatment [APACHE Ⅱ: 21.05±8.58 vs. 24.90±5.63, 18.70±11.21 vs. 26.65±7.67; PDR: (47.71±29.49)% vs. (61.00±23.29)%, (36.79±18.49)% vs. (56.12±18.16)%; PEEP (cmH2O, 1 cmH2O = 0.098 kPa): 4.40±3.14 vs. 5.75±2.59, 3.80±2.55 vs. 7.55±3.32], but there were no statistically significant differences between the two groups before and after treatment (allP > 0.05). After treatment, the OI was significantly higher and the PA-aO2 was significantly lower than those before treatment in the two groups, and the degrees of improvement of the observation group were more remarkable than those of the control group [OI (mmHg, 1 mmHg = 0.133 kPa): 224.72±85.12 vs. 141.37±45.82, PA-aO2 (mmHg): 132.60±46.64 vs. 204.30±121.2, bothP < 0.05]. The 28-day mortality of observation group was lower than that of control group, but no statistically significant difference was seen [15% (3/20) vs. 25% (5/20),χ2 = 0.156,P > 0.05). Binary logistic regression analyses showed that the PA-aO2 [odds ratio (OR) = 0.958,P = 0.013, 95% confidence interval (95%CI) = 0.927 - 0.991], APACHE Ⅱ score (OR = 0.882,P = 0.010, 95CI = 0.803 - 0.970), GCS (OR = 1.399, P = 0.004, 95%CI = 1.111 - 1.761) and PDR (OR = 0.907,P = 0.002, 95%CI = 0.853 - 0.965) after treatment were the independent predictors of 28-day mortality.Conclusion Nicorandil can significantly improve oxygenation, but cannot reduce 28-day mortality in patients with ARDS.
