Objective To made the animal model which is similar to the human pyelonephritis to strengthen the experimental basis for the therapy of acute urologic infectious disease. Method Using the method of semi-ligation of the ureter on single lateral and the injection of Enterobacter into the bladder to get pathologic transformation. Simultaneously, giving the different preparation of Zishen- tongguan Capsule, Sanjin Pills to intervene the models. Result Zishentongguan capsule middle dosage, western medicine treatment team had get obviously effect on rat body weight increasing, the drug treatment were validity. Conclusion The rat model with the acute nephropyelitis is similar to the character in the break of human, which manifest on the appearance, mental condition, body weight coefficient, kidney weight coefficient and pathologic change of the kidney. Succeed in the model establishment.

Objective:To study the clinical effect of corticosteroids (C S) with small dosage in the recurrence control of pemphigus. Methods: 25 cases of pemphigus were diagnosed by clinical and pathological examinati on.They were treated with CS at 60-80 mg/d in acute stage for symptom control.Th en,the dosage of CS was decreased by 5 mg in each following 2 weeks untill it re ached 2.5 mg/2 d. The treatment of 2.5 mg/2 d was continued for 1 year and was a ssisted with tripterygium polyglycoside, compound thalidomide, compound cyclopho sphamide (compounded with total saponins of ginseng), dapsone, and/or some kidne y-supplementing herbs. The patients were followed-up for 9~16 years.Re sults:No recurrence was observed in 16 cases(64%).Recurrence was found i n 9 cases(36%),among them 7(28%) were with light symptom and 2(8%) severe. Sever e side-effect was not found in all cases. Conclusion:The recurr ence of pemphigus may be controlled without severe side-effect by long-term us e of small dosage of CS assisted with proper immuno-inhibitors, immuno-regulat ors and/or some kidney-supplementing herbs.

The article analyses the protrudent problems in teaching foreign students and put forward some countermeasures.

Aurora-B as an important kinase to adjust the cell normal mitosis is a potent target for cancer treatment. Aurora-B is overexpressed in a broad range of tumor and tumor cells are more sensitive while Aurora-B is inhibited. Due to the key role of the Aurora-B in cell mitosis, the development of its inhibitors is becoming more and more important. Several small molecules inhibit with a similar efficacy both Aurora-A and Aurora-B, however, in most cases the effects resemble Aurora-B disruption by genetic methods, indicating that Aurora-B represents an effective therapeutic target. There were several Aurora-B kinase inhibitors which had entered the clinics and displayed good antitumor activity. In this review, we will outline the functions of Aurora kinase B in normal cell division and in malignancy. We will focus on recent preclinical and clinical studies that have explored the mechanism of action and clinical effect of Aurora-B inhibitors in cancer treatment.

Objective To explore the nursing measures of patients with pure diffuse axonal injury (DAI)treated by multi-step sub-hypothermia therapy.Methods The nursing care of pure DAI patients treated by multi-step sub-hypothermia therapy,which included the traumatic condition evaluation before treatment,the nursing care during treatment,the nursing care after treatment but also in coma,and the nursing care after palinesthesia.Results The intracranial pressure and concentration and lactic acid in blood and cerebrospinal fluid alleviated.The forehead expanded.The disability rating scale(DRS)decreased.While the incidence of sub-hypothermia related complications did not increased.Conclusions The elaborative nursing care aiming at different pathogenetic conditions,different stages is the first guarantee in the treatment of pure DAI with multi-step sub-hypothermia therapy.

Objective To evaluate the effects of different concentrations of dexmedetomidine on large-con-ductance Ca2+-activated K+ (BKca) channels in the rat mesenteric arterial smooth muscle (MASM) cells.Methods Sprague-Dawley rats of both sexes,weighing 180-220 g,were used in this study.Single MASM cell was freshly isolated from mesenteric arteries in two steps.Ten cells were chosen and studied.When holding potential was 40 mV and the concentration of free calcium ions was 10-7 mol/L,inside-out patch-clamp technique was used to record the single BKCa channel current before and after application of different concentrations of dexmedetomidine (0,10-9,10-8,10-7,10-6,10-5 mol/L).Total open probability (NPo),amplitude (Am),mean open time (To) and mean close time (To) of single BKca channel were observed and recorded.Results Compared with the baseline value,dexmedetomidine 10-7,10-6 and 10-5 mol/L increased NPo in a concentration-dependent man-ner,and dexmedetomidine 10-9,10-8,10-7,10-6,10-5mol/L shortened Tc (P ＜0.05 or 0.01).Compared with the value obtained when the concentration of dexmedetomidine was 10-9 mol/L,Tc was significantly shortened when the concentration of dexmedetomidine was 10-8 mol/L (P ＜ 0.05),and no significant change was found in Am and To obtained when different concentrations of dexmedetomidine were applied (P ＞ 0.05).Conclusion Dexmedetomidine 10-7,10-6 and 10-5 mol/L activate BKca channels in rat MASM cells in a concentration-depen-dent manner,which is one of the mechanisms of decrease in blood pressure by dexmedetomidine.

Objective To construct and implement theSTARnurse training model, and discuss its application effect and the problems that should be paid attention to, and to provide operational cases and practical basis for nursing clinical education. Methods Through literature review and expert consultation, the framework and content of STAR nurse training model were set up and implemented. The questionnaire survey and semi structured in-depth interviews were conducted among the nurses in the hospital to evaluate the effect of improving the nurses′self-directed learning ability. Results After the implementation of the project, the scores of the three dimensions of self-management, desire for study and self-control were (3.67±0.57), (4.05±0.54), (3.99±0.50) points, which were higher than (3.55±0.49), (3.71± 0.52), (3.53±0.42) points before implementation. The difference was statistically significant (P<0.05 or 0.01). The semi structured in-depth interviews showed that all the nurses believed that STAR nurse training model could promote independent learning and stimulate interest in learning. 14 nurses thought it was beneficial for the nurses to find the problems. Conclusions STAR nurse training model can create a favorable learning environment for nurses, and stimulate the learning motivation. It plays a positive role in improving nurses′ability of self-directed learning.

Medical microbiology is basic course of medicine.In order to improve teaching quality,we employ discussing-mode education in microbiology.This education style can not only enlighten and train poly-directional thought ability,capacity of bringing forth new ideas and pioneering spirit,but draw close the distance between students and modern life science,which make microbiological course become beginning of exploring microbiology.The employment of education style of discussing microbiology new advance is effective pathway of exploring most suitable high-quality person of talent training.
