Objective To study the mechanism of oxidative damage in myocardial tissue after limb ischemia reperfusion (IR), and the protective effects of heme oxygenase-1 on myocardial injury in experimental rats. Method The models of bilateral hind limbs ischemia and reperfusion in rats were established by using tourniquets applied to the roots of both hind limbs until palm blanched and pulseless for 4 hours. A total of 56 SD rats were randomly (random number) divided into 7 groups, namely one normal control group ( n = 8) and 6 ischemia-reperfusion groups as per different lengths of reperfusion time, e. g. 2 hrs, 4 hrs, 8 hrs, 16 h rs and 24 hr ( n = 8 each). The experimental rats were sacrificed after different lengths of reperfusion time. Specimens of myocardium and blood were taken for assays of malonaldehyde (MDA), superoxide dismutase (SOD) and myeloperoxidase (MPO), and pathological changes of myocardium were observed, and the expressions of HO-1 mRNA in myocardium were detected. Data were analyzed with ANOVA. Results (1) Compared with the control group, the levels of serum MDA and myocardial MDA of rats were increased in all IR groups and were higher (P < 0.05), and the levels of MDA reached the peak after reperfusion for 4 hours. The levels of serum SOD and myocardial SOD in rats of all IR groups were decreased and lower than those in rats of the control group ( P < 0.05), and the levels of serum SOD dropped away to the lowest point after reperfusion for 4 hours, and the levels of myocardial SOD fell off to the bottom after reperfusion for 8 hours. The levels of serum MPO and myocardial MPO were significantly increased in rats of all IR groups compared with the control group (P < 0.05). The levels of serum MPO reached peak after reperfusion for 4 hours, and the levels of myocardial MPO were increased to the highest spot after reperfusion for 6 hours. (2) The pathological changes in myocardium showed the most severe damage after reperfusionfor 4-6 hours.(3) After reperfusion for 2 hours, there were no significant differences in the expression of HO-1 mRNA between IR groups and control group (P >0.05), and after reperfusion for 4 hours and over, the expressions of HO-1 mRNA were markedly increased in IR groups and reached peak after reperfusion for 16 hours in comparison with the control group (P < 0.05). Conclusions The activation of neutrophils and free radicals may play a primarily adverse role in myocardial injury after limb IR, and the increase in the expression of HO-1 mRNA lessens the harm effects of IR on myocardium.

Objective To investigate the characteristic and the value of renal solid lesions' boundary at contrast-enhanced ultrasonography(CEUS). Methods The study included 225 patients (124 males, 101 females) with renal 239 solid lesions [133 renal cell carcinoma(RCC) and 106 benign lesions]. The enhanced mode of lesion boundary at CEUS was observed. The histopathologic pseudocapsule of RCCs was analysed.Results Enhanced modes of all lesions' boundary at CEUS were classified as: type Ⅰ , iso-enhanced boundry in whole phase, 82.85 % (198 of 239) ;type Ⅱ , a perilesional annular highly-enhanced signal at early phase,4.18% (10 of 239);type Ⅲ ,perilesional annular highly-enhanced signal in whole phase,9.62% (23 of 239) ;type Ⅳ, perilesional annular highly-enhanced signal in midium and late phase, 1.25 % (3 of 239) ;type Ⅴ ,iso-enhanced boundry in the mdium and late phase with no enhancment at early phase, 2. 09% (5 of 239). The distribution of types Ⅰ , Ⅱ , Ⅲ between groups were significant different( P=0.000, 0.046,0. 000), the type Ⅳ and Ⅴ was not ( P = 0.256,0.068). The distribution of perilesional annular highlyenhanced signal between benign and RCC groups was statistically different (x2=29. 681, P=0.000).Regared it as a diagnostic criteria of RCC,the sensitivity was 26.32% (35/133) ,the specificity was 99.06%(105/106) ,the positive predictive value was 97.22% (35/36),the negative predictive value was 51.72%(105/203) ,and the accuracy was 58.58% (140/239). The perilesional annular highly-enhanced signal was not correlated with the pseudocapsule in pathology ( P = 1. 000). Conclusions The boundary enhancement mode of renal solid lesions at CEUS was divided into five types. The perilesional annular highly-enhanced signal was important in diagnosis of RCC,which was not correlated with the pseudocapsule in pathology.

Objective To observe the clinical effect of treating advanced esophageal carcinoma with three-dimensional conformal radiotherapy combined with chemotherapy and traditional Chinese medicine.Methods 36 cases with advanced esophageal carcinoma were randomly divided into a eontrol group and a treatment group.The control group was treated with conventional radiotherapy combined with chemotherapy,and the treatment group was treated with three-dimensional conforrnal radiotherapy combined with chemotherapy and traditional Chinese medicine.The short-term effect,toxicity and long-term effect were observed,and cause of death was analyzed.Results The complete remission rate in the treatment group was significantly higher than that of the control group(P＜0.05).The toxicity of the treatment group was markedly decreased.One and three years'survival rate between the two groups had a significant difierent(P＜0.05),but five years'survival rate between the two groups had no significant difference(P＞0.05).Local uncontrolled rate and recurrence rate in the treatment group were significantly lower than those in the control group(p＜0.05).Conclusion The treatment of three-dimensional conformal radiotherapy combined with chemotherapy and traditional Chinese medicine on advanced esophageal carcinoma was better than conventional radiotherapy combined with chemotherapy.

There are some problems in the teaching of medical physics course,such as low learning initiative,deficient grasp of concept,and obstacles to realize the internalization and practical application of knowledge.The PAD (presentation-assimilation-discussion) class is applied in the course,in order to improve the students' learning state.PAD class is a teaching mode proposed from a psychological point,which advocates that teaching is the first before students start to learn and has an equal treatment on students' discussions and teachers' instruction,supporting independent learning.The teaching measures include:selecting course content to reach the balance between simplification and detailed interpretation;assigning open homework based on the course;dividing the class discussion into four steps;assessing students based on the performances of homework and final examinations.The research has shown that the PAD class facilitates improving the students' initiative of study and promoting the absorption and application of knowledge.

Objective To report the result of analysis of 72 cases of facial cutaneous sporotrichosis. Methods Seventy-two patients were included in this study. They were diagnosed as facial cutaneous sporotrichosis according to clinical mainfestations and fungal culture. Histopathological examinations were done in some atypical cases. The patients were treated with combined antifungal agents. Results The lesion forms were varied, in which lymphangitic cutaneous form accounted for 9.72% and fixed cutaneous form accounted for 90.28% respectively. Nineteen cases (26.4%) had a history of skin trauma before the cutaneous lesions. All of the patients were successfully treated with potassium iodide and/or itraconazole, terbinafine for 6-8 weeks. Conclusions The skin lesions and mycological examination are the important evidences for the diagnosis of sporotrichosis. The main form of the facial cutaneous sporotrichosis is the fixed cutaneous form. The misdiagnosis rate is 16% in primary level clinics. Potassium iodide is an effective and inexpensive medicine in the treatment of cutaneous sporotrichosis.
