Unstable plaque is one of the major sources of microemboli.The microembolic signals indicate that the patients had unstable plaques and are prone to cerebral infarction recently.A series of adhesion molecules involved in the regulation of inflammatory response and functional changes of cerebral microcirculation during ischemic brain injury.The interaction among the adhesion molecules is conducive to leukocyte adhesion,migration,and platelet aggregation,thereby promoting inflammatory response and thrombosis.Recent studies have indicated that adhesion molecules are closely correlated with the instability of atherosclerotic plaques,which may have involved in the formation process of microemboli.The further study of adhesion molecules and microemboli contributes to implementation of drug intervention.It has a positive significance for the prevention and treatment of cerebral ischemia.

Objective To investigate the effects of health management on risk factors of cardiovascular diseases in community residents.Methods A total of 208 adults from one single community who visited our health check-up center were randomly assigned to the control group(receiving routine consultation,n =104)and health management group(receiving health management intervention,n =104).At 1-year follow-up,fasting blood glucose(FBG),lipid profiles,and blood pressure(BP)were measured and risk factors of cardiovascular were surveyed.t or x2 test was used for data analysis.Results No difference of clinical data was found between the two groups at baseline.Follow-up results indicated that absolute risk of cardiovascular diseases,number of risk factors,health satisfaction,sick leave,daily vegetables intake and physical exercise,and BP were significantly improved in the health management group.Ten-year absolute risk of cardiovascular diseases(0.8 ± 0.4 vs 1.3 ± 0.5),number of risk factors(172 vs 283),and sick leave per year(118 d vs 264 d)were significantly decreased in the health management group when compared to the control group(all P ＜ 0.05).Furthermore,health satisfaction(83.7％(87/104)vs 52.9％(55/104)),and daily vegetables intake(520.5 g vs 348.3 g)and physical exercise(1.2 h vs 0.3h)were significantly improved in the health management group(all P ＜ 0.05).Conclusion Health management may be effective in decreasing risk factors of cardiovascular diseases in community residents.

Objective To assess the efficacy of extensive esophagogastric devascularization with splenectomy for surgical treatment of portal hypertension complicating cirrhosis of liver, and to explore the pathogenesis of chronic congestive splenomegaly. Methods A retrospective analysis of clinical data of 232 patients of portal hypertension complicating cirrhosis of liver having undergone extensive esophagogastric devascularization with splenectomy was made. Pathological alterations and extracellular matrix productive cells of the congestive splenomegaly were studied both immunohistochemically and histologically. Results The functional markers including the numbers of PLT, WBC, and PTA in the peripheral blood and serum Alb were significantly improved after the operation compared with that of before the operation. Careful pre-operation preparation, replenishment of blood loss during the operation, postoperative drainage of the splenic bed, and prevention of complications were efficiently carried out. The mean volume of CCS spleens was 1 423.67?738.69cm 3. There was an obvious increase in the numbers of vimentin-, ?-SMA-positive cells in the CCS tissues, as well as CD68-positive macrophages. Conclusions The results indicated that extensive esophagogastric devascularization with splenectomy was a reasonably effective alternative therapy for patients with portal hypertension complicated by esophageal varices and congestive splenomegaly. Adequate replacement of blood lost in prevention of operation and postoperative complications were essential for satisfactory recovery of the petient. The activation of macrophagic system, with proliferation of fibroblasts and myofibroblasts, might participate in the pathogenesis of congestive splenomegaly.

Objective To investigate the relationship of microembolic signals (MESs) between the degree of symptomatic carotid artery stenosis, ultrasonic characteristics of plaques, peak systolic velocity at the stenotic site and risk factors for stroke. Methods A total of 52 patients with symptomatic carotid artery stenosis were enrolled. MESs of bilateral middle cerebral arteries were monitored and detected by carotid color Doppler flow imaging. Results The positive rate of MESs on the symptomatic sides was significantly higher than that on the asymptomatic sides (28. 8% vs. 4. 5%, P < 0. 05). The positive rate was not significantly correlated with the degree of stenosis, ultrasonic characteristics of plaques, peak systolic velocity on the stenotic sides, and risk factors for stroke. Conclusions MESs mainly occurred on the symptomatic sides of carotid artery stenosis, and they were more closely correlated with unstable plaques.

Objective To probe into the clinical effect of the sickbed management system for student nurses.Methods The student nurses at the first department of gynecology from June 2010 to April 2012 were set as the experiment group,in which the sickbed management system was used so that they completed their nursing work at fixed shifts and sickbeds under the nursing teacher’s instructions.The student nurses at the second department of gynecology during the same period were set as the control group,in which the student nurses took different tasks for unfixed sickbeds at different shifts every day.The two groups were compared in terms of the student nurses’knowledge about the patients’diseases and the degree of patients’satisfaction with their nursing work.Result The experiment group was significantly better than the control one in terms of student nurses’knowledge about the patients’diseases and the degree of patients’satisfaction with their nursing work(both P<0.05).Conclusion The sickbed management system for the student nurses may not only enhance nurses’sense of responsibility for their work,but also improve the quality of nursing teaching and patients’ satisfaction with the nursing service.

Object To probe into the objectivity and authenticity of four properties (cold, heat, warm, and cool) of raw Coptidis Rhizoma (RCR) and their preparations from biophysics and biochemistry. Methods Microcalorimetry was used to obtain the metabolic growth power-time curve of bacteria affected by the total alkaloid in different preparations of RCR and biothermokinetic parameters. Combined with the records of ancient herbal literatures, the influence of properties by different preparations to RCR were synthetically evaluated. Results All the effective total alkaloid in different preparations of RCR can restrain the Escherichia coli growth and metabolism in different level. Drugs, such as Coptidis Rhizoma Stir-fried with ginger juice (CRGJ), Coptidis Rhizoma stir-fried with wine (CRW), and Coptidis Rhizoma stir-fried with Fructus Evodiae (CRFE), with a little Warm Property can decrease the multiplication rate constants of E. coli index and increase heat output in growth metablism remarkably, while the drugs, such as RCR, Coptidis Rhizoma stir-fried with vinegar (CRV), and Coptidis Rhizoma stir-fried with gallbladder juice (CRGBJ), with a little Cold Property can decrease the multiplication rate constants and increase heat output a little. There was a stable difference between them. Conclusion Microcalorimetry is a new and useful mean for the study of the properties of tradition Chinese medicine.

Objective:To investigate the prognostic value of systemic inflammatory score (SIS) in prognostic assessment of patients with unresectable metastatic colorectal cancer (mCRC).Methods:The clinical data of 130 patients with unresectable mCRC in Affiliated Haikou Hospital of Xiangya Medical College of Central South University from January 2014 to December 2016 were retrospectively analyzed. The relationship between SIS and clinicopathological characteristics of unresectable mCRC patients was also analyzed. The survival analysis was made by using Kaplan-Meier. The risk factors affecting the prognosis of unresectable mCRC patients were analyzed by using Cox regression model to make univariate and multivariate analysis.Results:According to SIS results, patients were divided into 0-score group (40 cases), 1-score group (58 cases), and 2-score group (32 cases). There were no significant differences in different SIS constitution patients stratified by age, gender, primary tumor location, functional status score, tissue type, RAS gene status, number of metastatic organs, peritoneal spread and molecular targeted therapy (all P > 0.05). Kaplan-Meier survival analysis showed that the 5-year overall survival rates of SIS 0-score, 1-score and 2-score group were 37.5%, 19.0%, 6.3%, respectively; and the difference was statistically significant ( χ2 = 3.152, P<0.01). Cox regression survival analysis showed that female, primary tumor location in right side and SIS (scores of 1-2) were independent risk factors for overall survival in patients with unresectable mCRC (all P<0.05). Conclusion:SIS may be an important indicator for prognostic assessment of patients with unresectable mCRC, and patients with high SIS have poor prognosis.

OBJECTIVE: To evaluate the efficacy and safety of Yiqing Shuangjie Capsule and Tablet in treating acute upper respiratory tract infection with wind-warm syndrome. METHODS: The multiple center, double-blinded, double-dummy and randomized controlled method was conducted. Three hundred and sixty patients were randomly divided into the treatment group A (n=120, treated with Yiqing Shuangjie Capsule and Chaihuang analogues), treatment group B (n=120, treated with Yiqing Shuangjie Tablet and Chaihuang analogues) and the control group (n=120, treated with Chaihuang Tablet and Yiqing Shuangjie Capsule analogues). Every drug was administered 3 pills each time. Patients in the three groups were all treated for 5 days and three times daily. The accumulated scores of syndrome, clinical symptoms, adverse effect and body temperature were recorded before and after the treatment. The safety indexes, such as routine tests of blood, urine and stool, hepatic and renal function tests and electrocardiogram (ECG) were taken before and after the treatment. RESULTS: Three cases were excluded and eighteen cases lost to follow-up. There were 343 patients who entered to the intention-to-treat (ITT) analysis and 339 patients fitted in the per-protocol population set (PPS) analysis. After treatment, the therapeutic effects of respiratory tract infection were calculated by ITT and PPS analysis respectively. The rates of total obvious effect were 84.96% and 87.27% respectively in the treatment group A, and the total response rates were 96.46% and 97.27% respectively. The rates of total obvious effect were 85.47% and 86.20% respectively in the treatment group B, and the total response rates were 97.45% and 97.41% respectively. In the control group, the rates of total obvious effect both were 72.57%, and the total response rates both were 99.12%. There was significant difference among the three groups (P<0.05). The effects of traditional Chinese medicine syndrome were also detected by ITT and PPS analysis respectively. In the treatment group A, the total obvious effect rates were 84.07% and 85.46% respectively, and the total response rates were 96.46% and 97.27% respectively.
