The emergent and severe diseases always shows the characteristics of acute course, severe condition, rapid changes, and many complications. The common treatments based on syndrome differentiation usually lacked dynamics and promptness. The treatment of emergent and severe diseases emphasized the importance of early interventions, which can reverse the acute trend of the diseases and improve the outcomes. This article discuessed in five parts, including the meaning and significance of trend identification, the physiological and pathological trend of the human body, the influence factors of diseases' trend, how to carry out a trend identification and intervention strategies of trend identification. It elaborated the theory about the trend identification in the emergent and severe diseases.

Objective To build a scientific,rational and practical evaluation index system for medical tutors.Methods Evaluation framework was initially constructed on the basis of literature analysis.Two rounds questionnaires investigation were conducted soon using Delphi method and the data were analyzed using descriptive analysis,independent samples of non-parametric test (Kreskas-Wallis test),expert reliability analysis,analytic hierarchy process and other methods.Results The results of two rounds of expert questionnaires showed that both recovery rate and acceptance rate of the questionnaires were more than 90％ and overall expert coefficient was 0.8957.The coordinate coefficient of the second-class index was 0.181,x2 =27.148,P ＜ 0.001,and that of the third-class index was 0.157,x2 =127.03,P ＜ 0.001.Experts' opinions were highly consistent.Conclusions Evaluation index system including three first-class indexes,seven second-class indexes and twenty-eight third-class indexes was established for medical tutors.The evaluation index system is of great importance in safeguarding postgraduate culturing quality and strengthening teaching staff construction.

Objective To explore the characteristics of uhrasonography of hepatobiliary cystadenoma. Methods The ultrasonographic characteristics of 5 cases with hepatobiliary cystadenoma were retrospectively analysed, and compared with the operation and pathology. Results The ultrasonography of 5 cases was multilocular cystic mass,which seems to be,but not indeed communicating with the biliary tree,in which irregular septation was demonstrated in two-dimensional structure and also with perforator vessels along in color Doppler flow imagineg. And in some cases small papillary tuft and small loci of calcification was noted on the septation. Conclusions Muhilocular cystic mass,locating along the biliary tree, however not communicating with the the biliary tree, is an important diagnostic basis of biliary cystadenoma. And it should be distinguished with other cystic tumor in the liver.

Objective To observe the clinical efficacy of Chuankezhi acupoint injection combined with nursing health care education for treatment of patients with chronic obstructive pulmonary disease (COPD) at stable stage complicated with spleen kidney deficiency syndrome.Methods A prospective study was conducted. 118 patients with stable COPD and spleen kidney yang deficiency syndrome admitted to Hangzhou Third People's Hospital and Zhejiang Xinhua Hospital from February to April 2014 were enrolled, and they were divided into an experimental group (60 cases) and a control group (58 cases) according to the random number table. Both groups were given conventional treatment [including oxygen therapy, bronchodilators, corticosteroids, rehabilitation therapy in accord with the Global Initiative COPD (GOLD)]. Simultaneously, in the experimental group, Chuankezhi acupoint injection was additionally given, once daily for 12 weeks, and appropriate corresponding health education was mentioned. The lung function, quality of life and prognoses of the patients were regularly followed up for 9 months and compared between the two groups.Results After 12 weeks, one second forced expiratory volume (FEV1), FEV1/forced vital capacity (FVC) and maximum voluntary ventilation (MVV) per minute in the experimental group were significantly higher than those in control group [FEV1 (L): 1.57±0.42 vs. 1.35±0.35, FEV1/FVC: (58.62±4.56)% vs. (50.36±4.35)%, MVV (L/min): 60.62±7.56 vs. 56.95±6.33, allP < 0.05]. The quality of life evaluation form for COPD (QLICD-COPD) was used to evaluate the physical function, psychological function, social function and specific modules scores, showing that the above items in the experimental group were significantly higher than those in control group (total score: 74.69±8.92 vs. 68.62±8.95, physical function score: 74.16±8.55 vs. 66.31±7.15, mental function score: 78.69±9.79 vs. 72.64±8.45, social function score: 75.45±6.75 vs. 70.36±6.12, specific modules score: 67.52±6.33 vs. 61.36±6.17, allP < 0.05); Barthel index score was also significantly higher than that in the control group (75.41±9.24 vs. 68.43±7.95,P < 0.05). Within 9 months of follow-up, the incidence of acute exacerbation of COPD in the experimental group was significantly lower than that in the control group [5.00% (3/60) vs. 17.24% (10/58),P < 0.05]. The re-admission rate was also significantly less in patients in experimental group compared with that of control group [1.67% (1/60) vs. 12.07% (7/58),P < 0.05]. Conclusion Chuankezhi acupoint injection with health education for treatment of patients with COPD at stable stage and spleen kidney yang deficiency syndrome has good clinical efficacy, worthy to be applied more widely.

By equality in the healthcare retorm we mean equal access to healthcare protection.Future reiorm should establish a fair value concept and make great efforts to solve the serious lack of fairness in the current healthcare system.Efficiency in the healthcare refers to not only higher revenue income of medical institutes but also to utmostly meet the citizens" needs for medical service.For the sake of the most cost - effective distribution of the insufficient budgets and medical resources,medical services have to be diversified for an improved efficiency. In the framework of the healthcare reform,relations between equality and efficiency is the unity of opposites,and top priority shall be given to equality while maintain efficiency.

Through the study of the pathology of sleep apnea-hypopnea syndrome, evaluation indexes, diagnosis requirements and so on, a portable sleep monitoring system was designed, which had the characteristics of convenience, wireless transmission and no disturbance. The system can be assessed by respiration monitoring and pulse oximetry, which is based on the pressure variation in miniature air-bag and spectral absorption method. It provides the value of the apnea-hypopnea index (AHI), which is used to evaluate OSAHS severity. The experiment of the system's stability and accuracy is done, which exhibits good performance, it can diagnose OSAHS effectively and provide convenience for home monitoring.

Through various common domestic and foreign electronic sphygmomanometers to test blood pressure, we find that when measuring high blood pressure or low blood pressure, there is a mismatch between the maximum inflation pressure and the blood pressure measurement, which often results in repeatedly inflating and deflating as well as the problem of high inflation pressure. In order to solve these problems and find a suitable maximum inflation pressure, two intelligent pneumatic solutions based on identifying of pulse wave are suggested and 700 groups of blood pressure experiments are done, then the two solutions are verified by experiments. The experiment proved that these solutions proposed have good stability and accuracy, they can solve the problems appeared in measuring blood pressure effectively, at the same time, the second solution that estimate the maximum inflation pressure during inflation is considered as the best one.
