The‘prevention and early treatment of diseases’conception as‘Huangdi Neijing’suggested,is the highest academic realm among the Chinese medical theory,it flows through the entire process of Chinese medical theory and diseases prevention.Four aspects of the prevention conception manifested in the process of Chinese medical prevention of diseases are: Taking preventive measures before confirmed diagnosis(health cultivation),impeding diffusion after confirmed diagnosis, deterring diffusion from deterioration,and restraining deterioration from being malignant.The malignant causal chain conversion of the coexistence of asthenia and sthenia is considered as the inducing links of critical illness’occurrence,evolution and transformation.Therefore,to intercept the malignant causal chain conversion comes to the key technique of Chinese medical remedy for critical illness.The‘prevention and early treatment of diseases’conception must impenetrate the versal process of treating critical illness.The overall clue and method of Chinese medical remedy for critical illness is to identify and grasp the vital contradiction and each respect of the malignant causal chain conversion which concurs with the evolution of the critical illness,simultaneously utilize the method which combined the prevention in etiology and pathogenesis with the remedy in etiology and pathogenesis,then actuate the pathologically changed organism to extricate from critical conditions at the first opportunity, finalizing with convalescence and recuperation thereafter.

Studies in recent years have demonstrated that stromal cell-derived factor-1 SDF-1/CXCR4 axis plays an important role in the process of angiogenesis. The expression of SDF-1 in ischemic tissue increases during cerebral ischemia. It binds to CXCR4 receptor on the surface of endothelial progenitor cells EPCs, and thus promotes bone marrow-derived EPC mobilization, proliferation, and migration to the ischemic areas and homing. EPCs differentiate into mature endothelial cells in the ischemic region, promote the formation of new blood vessels, and thus irrlprove the blood supply to ischemic tissue. This article reviews the effect of SDF-1/CXCR4 axis in the treatment of cerebral ischemia with EPCs.

Objective To analyze the epidemiological characteristics of overseas imported malaria reported in Chongqing City from 2011 to 2015,so as to provide the evidence for improving the imported malaria control strategies. Methods The epi-demiological data of overseas imported malaria cases were collected and analyzed descriptively for the species,original coun-tries,diagnosis and treatment in Chongqing City from 2011 to 2015. Results A total of 148 overseas imported malaria cases were reported in Chongqing City from 2011 to 2015,in which 96(65.54%)cases were falciparum malaria,and 37(24.32%) cases were vivax malaria;125(84.46%)cases were infected in Africa,and the rest of 23(15.54%)cases were infected in Southeast Asia. Most of the patients were 30 to 50 years old male workmen,and the ratio of male to female was 11.42:1. There was no obvious seasonal distribution among the reported timelines of the cases;however,there were two small peaks from June to August and from January to February. The median interval time of imported malaria cases from malaria onset to see a doctor was 1 day and from seeing the doctor to get malaria diagnosis was 2 days. The patients'first selected institutions were county medical institutions(50 cases,33.78%),then provincial medical institutions(36 cases,24.325%)and private doctors(20 cases,13.51%),and only 79(53.38%)patients got malaria diagnoses in their first selected institutions. The standard treatment were provided to 142(95.54%)cases. There were 43(29.05%)patients had serious complications and three patients were dead. Conclusion It is very important to enhance the multi-sector's collaboration to establish the collaborative investigation mechanism for screening malaria patients,and strengthen malaria health education for overseas workers and training courses in primary care medical institutions.

Objective:To investigate the clinical significance of dynamic analysis of plasma brain natriuretic peptide in patients with dilated cardiomyopathy with chronic heart failure.Methods:Ninety patients with dilated cardiomyopathy with chronic heart failure admitted into our hospital firom March 2012 to March 2016 were divided into group A (20 cases),group B (38 cases),and group C (32 cases) according to the NYHA grading.The plasma BNP levels and LVEF,LA,LVEDD,and LVESD in the three groups were detected and compared.The correlation of plasma BNP and cardiac function and ultrasonic cardiogram indexes were analyzed.And the capability of plasma BNP and LVEF in diagnosis of patients were analyzed and compared.Results:The plasma BNP level in group C was markedly higher than that of group A and group B (P＜0.05),and that in group B was much higher than that of group A (P＜0.05).And LA in group C was significantly higher than that of group A (P＜0.05),while differences in LVEF,LVEDD,and LVESD were not obvious (P＞0.05).The plasma BNP was positively correlated to NYHA grading,but had no significant correlation with the LVEF,LVEDD,LVESD,and LA (P＞0.05).Based on results of receiver operating characteristic curve analysis,plasma BNP =523.5 pg/mL was the threshold value for identification of patients with NYHA Ⅲ and Ⅳ (AUC=0.901,P＜0.001),while LVEF had not the capability (AUC=0.392,P=0.276).Conclusion:Detection of plasma BNP level had important clinical significance on diagnosis,screening and cardiac functional grading of patients with dilated cardiomyopathy with chronic heart failure.

Implant surface modified coating can improve its osteoinductivity, about which simple calcium phosphate coating has been extensively studied. But it has slow osteointegration speed and poor antibacterial property, while other metal ions added, such as nano zinc ion, can compensate for these deficiencies. This paper describes the incorporation form, the effect on physical and chemical properties of the material and the antibacterial property of nano zinc, and summarizes the material's biological property given by calcium ion, zinc ion and inorganic phosphate (Pi), mainly focusing on the influence of these three inorganic ions on osteoblast proliferation, differentiation, protein synthesis and matrix mineralization in order to present the positive function of zinc doped calcium phosphate in the field of bone formation.

We have established a digital coronary angiograph-analyzing system on the principle of coronary angiographic impulse response, and combined the system with the quantitative coronary analysis (QCA) for investigating the coronary microcirculation (Tmicro(-1)), the minimal stenotic diameter of coronary (MLD) and coronary hemodynamic parameters (mAP, CFV, Rcor) in 20 patients with coronary stenosis. The results showed the minimal stenotic diameter (MLD) and Tmicro(-1) decreased, with the increase of stenosis of proximal coronary. After successful percutaneous coronary intervention treatment, the Tmicro(-1) increased with the increase of MLD and was in linear correlation with MLD (r = 0.87, P < 0.001). In conclusion, The index Tmicro(-1) detected by coronary digital angiographic impulse response analysis system in combination with CFV and QCA would help to evaluate the level of integrated diagnosis of coronary lesion in regard to anatomy and physiology as well as to macro and microcirculation.
