OBJECTIVE:To prepare different compound scald preparations and to investigate their repairing effects for deep Ⅱ? scald in rabbits.METHODS:The deep Ⅱ? scald model was established in depilated rabbits by infrared radiation.Then the rabbits in the trial groups were treated with the same drug at different dosage and different forms of medication:compound scalded gels,compound scalded ointments and the compound scalded films,with Moist Exposed Burn Ointment as positive control and 0.9% NaCl aqueous solutions blank.After a certain time of treatment,the contraction of the scald skin was observed and the average value of the diameter of the scald skin was calculated.RESULTS:In three trial groups and Moist Exposed Burn Ointment positive control group,no scald infection occurred,and the healing surfaces of the scalds were all smooth and even.However,the healing time was different between 3 trial groups and Moist Exposed Burn Ointment positive control group,with compound scalded gels showing the best efficacy in that the scald surfaces were free from infection,the healing surfaces were smooth and even,and the contracted diameter of the scalded skin was significantly lower than in other groups,showing significant differences as compared with other groups(P

Objective To investigate the correlation between the severity of coronary artery disease with se-rum bilirubin and left ventricular cardiac function. Methods Two hundred and six patients underwent blood bio-chemical ,color-echocardiography and angiography of coronary artery. The patients were divided into 4 ordinal groups according to the Gensini score indicating the severity of coronary artery disease. Results There were significant differences in total bilirubin(TBIL), left atrial dimension (LAD), left ventricular dimension (LVD) and left ventric-ular ejection fraction (LVEF) between the four groups(P<0.05 or P<0.01). The Spearman correlation coefficent between Gensini's scores and LAD, LVD were 0.280 (P=0.000) and 0.176 (P=0.011), respectively. The Spearman correlation coefficient between Gemini's scores and TBIL, LVEF were -0.541 (P<0.000) and -0.222 (P=0.001), respectively. The multiple linear regression between the Gensini's score and parameters showed that TBIL and LVD were independently correlated with the Gensini scores (P=0.000 and P=0.002, respec-tively). Conclusions TBIL and LVD were independently correlated with Gensini's score. LVEF was negatively cor-related with the severity of coronary disease and is a useful predictor for the severity of coronary atherosclerotic heart disease.

Objective To investigate the expressions of RTN4 and TG2 in papillary thyroid cancer tissues and their clinical pathological significance.Methods A total of 40 samples of papillary thyroid cancer tissues and 20 samples of para‐carcinoma tissues were collected from the Department of Pathology ,Renmin Hospital of Wuhan University ,China.The expression levels of RTN4 and TG2 were detected by means of immunohistochemical staining and their relationship with clinicopathological charac‐teristics of papillary thyroid carcinoma was analyzed.SPSS 13.0 soft package was used for one‐way analysis of variance and SNK test of the average absorbance and the average positive area rate (α=0.05).Bivariate correlation analysis of the positive area rate of the expressions of RTN4 and TG2 was conducted (α=0.05).Results ①The expression levels of RTN4 and TG2 were much higher in the papillary thyroid carcinoma tissues than those in the para‐carcinoma tissues (P<0.05). ② The expres‐sion levels of RTN4 and TG2 were significantly higher in lymph node metastasis group than those in the group without lymph node metastasis (P<0.05).The positive expression rates of RTN4 and TG2 were much higher in clinical stage Ⅰand Ⅱ groups than those in clinical stage Ⅲ and Ⅳ groups (P<0.05).They were significantly increased in low differentiation group than in high or moderate differentiation group (P< 0.05).The expressions of RTN4 and TG2 were not statistically associated with tumor size ,age and sex (P>0.05). ③The positive correlation was found between the expressions of RTN4 and TG2 in papilla‐ry thyroid carcinoma tissues (r=0.587 ,P<0.05).Conclusion ① The expressions of RTN4 and TG2 were up‐regulated in pa‐pillary thyroid carcinoma tissues ,which is related with over‐proliferation and increase of apoptosis resistance of cancer cells. ②RTN4 and TG2 play an important role in the proliferation and metastasis of papillary thyroid carcinoma. ③ RTN4 and TG2 may play a synergistic role in the development of papillary thyroid carcinoma.

Objective To investigate the adjustment and value of lymphocyte G protein-coupled receptor kinase-2 (GRK2) protein levels in patients with acute coronary syndrome(ACS). Methods Forty-two patients with stable angina pectoris (SAP), 44 patients with unstable angina pectoris (UAP), 43 patients with acute myocardial infarction (AMI), and 46 patients with normal coronary angiography (NCA) in hospital were enrolled in this study. Lymphocyte GRK2 protein levels were analyzed by Western blot in 24 h after admitted to hospital. Heart rate variability (HRV) analysis was performed based on 24 h Holter electrocardiogram (ECG) monitoring. Cardiac functions were measured using ultrasonic cardiogram. The results were compared and the relationship between GRK2 protein levels and HRV, cardiac functions index was analyzed. Results The level of lymphocyte GRK2 in AMI group, UAP group, SAP group and NCA group was (209.8 ± 63.9)%, (165.6 ± 60.2)%, (131.7 ± 51.8)% and (125.3 ± 50.6)%. The levels of lymphocyte GRK2 in AMI group and UAP group was significantly higher than that in SAP group and NCA group .Moreover, the level of GRK2 was the highest in AMI group, and there were significant differences (P<0.01). The level of lymphocyte GRK2 had negative correlation with high frequency(HF), low frequency(LF), LF/HF, standard deviation NN interval (SDNN), standard deviation of the average normal RR interval for 5-minute segments (SDNNI) and left ventricular ejection fraction (LVEF) (r =-0.52,-0.47,-0.53,-0.56,-0.49,-0.51, P < 0.01). Conclusions The rise of lymphocyte GRK2 protein levels is significantly associated with increased sympathetic nerve excitability and deterioration of cardiac function.
