Objective To investigate the predicting value of serum sST2 on risk stratification and prognosis in elderly patients with acute heart failure (AHF).Methods Total of 75 AHF patients aged 60 to 93 were selected in our study who were in Beijing Hospital during 2013.1-2014.8,including 40 cases of male and 35 cases of female.Moreover,38 healthy people aged 70 to 80 were chosen as control group,which contains 18 cases of male and 20 cases of female.Follow-up was performed 1 year after acute attack.We defined the end of observation as recurrence of heart failure or any causes of death.The data was analyzed by SPSS19.0.Results Compared with control group,sST2 level (pg/mL) was significantly elevated in AHF group [(596.9 ±181.2) vs.(1 698.9 ±797.0),P ＜0.001].No significant difference was found between male and female (1 713.1 ± 1 322.2 vs.1 727.5 ±867.1,P =0.956).sST2 level was significantly different between patients with different clinical heart function grade [1 439.5 ±694.5 (mild-Ⅰ and Ⅱ grade) vs.2 057.8 ± 1428.6 (severeⅢ and Ⅳ grade),P =0.026].Among the 75 AHF patients,sST2 level was higher in patients with endpoint events than those without endpoint events [(2 234.4 ± 1 308.5) vs.(1 162.3 ±452.6),P=0.000].According to the independent risk factors of unconditioned logistic bivariate regression model analysis,the levels of sST2,NT-proBNP and the clinical heart function Grade had independent predicting value of AHF (OR value were 1.003,1.001 and 7.46 respectively).We found that the cutoff value of sST2 (1 760 pg/mL) may be an valuable evaluation marker of prognosis,the sensitivity and specificity was 64％ and 92％,and the positive and negtive predictive rate were 89％ and 70％.The accuracy rate was 77％.Combined with NT-proBNP to predict the prognosis of AHF,the result would be more exciting.The area under the ROC curve is 0.889.The endpoint event rate of the patients whose level of sST2 was below 1400pg/mL and NT-proBNP level below 4000pg/mL was 7％,while the data in patients whose level of sST2 is above 1400 pg/mL and NT-proBNP above 4000pg/mL was 95％.Conclusions Early at admission of AHF in elderly patients,sST2 began to elevate markedly related with the extent of heart failure.The result shows that the level of sST2 may be used to evaluate patient.The elevation of sST2 has independent predictive value to the prognosis of AHF.It will be better to predict the prognosis combining ST2 with other biomarkers such as NT-proBNP.

Objective To assess the application values of real-time three-dimensional transesophageal ultrasound (RT3D-TEE) technology in the diagnosis and treatment of artificial mitral paravalvular leak (PVL). Methods Fifty-one cases of artificial mitral PVL patients were received two-dimensional transesophageal ultrasound (2D-TEE) and RT3D-TEE examination before and after surgery. Accuracy analysis was performed between the two kinds of test. Results The diagnostic accuracy of RT3D-TEE technique in patients with PVL drain port positionwas significantly higher than that of 2D-TEE technology , and the data of PVL drain port size by RT3D-TEE technique is significantly larger than that of 2D-TEE technique (P < 0.05, respectively). Conclusion The PVL laboratory diagnosis based on RT3D-TEE is accurate and reliable , and RT3D-TEE can assist doctors to diagnose before operation , and can provide real-time ultrasound information from intraoperative monitoring , and monitor the postoperative efficacy of patients .

Objective To open pterygopalatine artery using autologous blood clot clogged the middle cerebral artery, resulting in cerebral infarction model of middle cerebral artery in the distal blood supply area.Methods Open PPA, ligation of ECA, embolus through CCA blood flow, rushed into the MCA distal embolus, cause infarction model. According to Bederson rating score the neural function.TTC staining to determine the infarction volume.Results Comparison of two operation models, scores were increased, and white infarcted area appears.There is no significant differences detected by statistical analysis.Conclusion Open PPA manufacturing cerebral infarction model rats of autologous blood clots could shorten the operation time, reduce the mortality rate.

Diabetes is a chronic noncommunicable disease,which is can't be cured,and only can be suppressed by long-term treatment and self-management.The clinical decision support system can simulate the thinking process of diabetes specialists in disease diagnosis,and can provide the regular medical treatment plans and recommend the optimal plans to doctors.Most of the existing clinical decision support systems are based on clinical guidelines,rule-based and case-based reasoning as well as ontology-based systems.The big data technology can acquire and process multiple heterogeneous data,and provide a more scientific personalized treatment plan.In recent years,a variety of big date processing methods have been applied to the clinical diagnosis of diabetes based on decision tree,neural network,fuzzy logic,support vector machine,APRIORI association rules and multidimensional analysis,and timing mining.However,these methods are still in preliminary stage.The framework of diabetes clinical decision support system based on big data technology was analyzed,and the future diagnostic and treatment methods were forecast.

Objective To investigate the relationship between p62 expression,and occurrence and metastasis of nasopharyngeal carcinomas.Methods Immunohistochemical method was used to analyze p62 expression in 123 nasopharyngeal carcinoma (NPC) cases and 30 chronic nasopharyngitis cases.The clinical pathological characteristics were analyzed.Results The positive rate of p62 protein in chronic nasopharyngitis nasopharyngeal epithelium,non-metastatic NPC tissue,and metastatic NPC tissues was 13.3％,66.67％,and 84.72％,respectively,and the difference was statistically significant.The expression of p62 protein in nasopharyngeal carcinoma patients with lymph node metastasis or distant metastasis was significantly higher than non-metastatic NPC patients (P ＜ 0.01 or P ＜ 0.05).However,the expression of p62 was not related to age,gender,tumor size,and TNM stage (P ＞ 0.05).Conclusions High p62 protein expression in nasopharyngeal carcinoma tissue is closely related to the occurrence and metastasis of nasopharyngeal carcinomas.It provides good reference value to predict NPC malignancy and metastases.
