Assurance system of Medical Quality is the core of teaching quality assurance work from colleges itself.This paper analysed the major factors affecting the teaching quality such as teachers,students,the teaching environment,teaching management based on quality management theory,making use of information technology to support the implementation of quality assurance system,constructing a system composed of five quality security system framework and forming protection of the quality of teaching based on information.

In order to improve the performance of the photorefraction device,shorten the detection time and improve the accuracy of measuring,the theory of a new kind of double-cranny eccentric photorefraction device is described.Some features and key point of technology are emphatically pointed out.A method is put forward to determine the ocular diopter by image processing.

Objective To explore the relationship between restoring Gissane angle and prognosis in calcaneal fracture surgery. Methods Forty patients with single side calcaneal fracture (SandersⅡ-Ⅲ), Gissane angle changed more than 15°and having performed open reduction and internal fixation with steel plate were enrolled. In them, 25 patients (experimental group) recovered Gissane angle in surgery referencing the healthy side with X-rays. Another 15 patients (control group) didn't recover Gissane angle. The ratio of calcaneum height and length was measured at 1 week after surgery. At 6 and 12 months after surgery, the function were valued by Maryland score. Results The ratio of calcaneum height and length in experimental group was significantly higher than that in control group:0.60± 0.04 vs. 0.55±0.05, and there was statistical difference (P<0.05). All the patients were followed up. At 6 and 12 months after surgery, the Maryland score in experimental group were significantly higher than those in control group:(88.9± 5.7) scores vs. (80.5±7.3) scores and (89.5 ±5.5) scores vs. (82.5 ±6.4) scores, and there were statistical differences (P<0.05). Conclusions Restoring Gissane angle is benefitial for prognosis. So in calcaneal fracture surgery, the Gissane angle should be recovered as much as possible referencing the healthy side.

A totel of 120 patients with CT or MRI proved as acute cerebral infarction group of anterior circulation and 90 non-infarction patients as the control group were studied. The diameter,inter median thickness( IMT) ,peak systolic velocity ( PSV ) , end diastolic velocity ( EDV ) , early shrinkage acceleration time ( AT ) , resistance index ( RI) ,and pulsatility index( PI) of carotid artery,and whether there was arteriosclerotic plaque or stenosis,and the properties of plaque were examined with color Doppler ultrasound. In acute cerebral infarction group of anterior cir-culation,the IMT was thicker that in the control group(P<0. 01). The incidence of the film thickness,moderate-se-vere stenosis and instable carotid artery plaque in infaiction group of anterior circulation were obviousely higher than those in the control group(P<0. 01). Arterial complete or incomplete occlusion was observed in severe cases. The blood flow parameters showed that the PSV and EDV of common carotid and internal carotid in acute cerebral in-farction group of anterior circulation were lowerer than those in the control group. RI and PI of internal carotid in a-cute cerebral infarction group of anterior circulation were higher than those in the control group(P<0. 05),while AT was lower than those in the control group.

Objective:To determine PRA and PRB expressions at mRNA and protein levels in endome-trial carcinomas,and to correlate the PRA and PRB expressions in tumours with clinical features inclu-ding grading,surgical stage,degree of myometrial invasion,and lymph node status.Methods:Sixty-sixendometrial carcinomas were investigated with Western blot assays and reverse-transcription polymerasechain reaction.The corresponding clinical information was collected.Spearman's rank correlation wasused to test for association between expressions of total PR and PR isoforms in endometrial carcinomas andclinical features.Results:At protein level,expressions of PRA and PRB were significantly inversely re-lated to grade(r=-0.343,r=-0.310,P

Teaching diagnosis is also called analysis of the scene of teaching. By using multimedia teaching in the classroom,teaching monitoring system for remote video,the use of the basic method of Chinese medicine in the diagnosis of the disease"look,smell,ask and feel" to watch video playback,we let the students purposefully observe teachers’ teaching,conduct the "Self-or experts",feeling the pulse diagnosis,and find the inadequate teaching and make recommendations for improvement so as to ultimately enhance the quality of classroom teaching purposes.

To meet with the need for culivating high-quality medical talents,the new teaching mode of problem-based learning (PBL) is attracting a lot of attention. Pathophysiology, which bridges basic medicine courses and clinical medicine courses,is more suitable for implementing PBL teaching mode. The teaching mode of incorporating case analysis is used into pathophysiology teaching by many ways is studied and an ideal result has been achieved.

A moderately thermoacidophilic iron-oxidizing bacterium,designated as strain MLY,was isolated from a coal spoil heap in China.The optimum of temperature for growth is 50℃～54℃.The optimum of pH is 1.2～1.4.The strain MLY is facultative autotroph and grows heterotrophically on yeast extract.It is able to oxidize ferrous iron(Fe 2+ ),pyrite(FeS 2),and elemental sulfur(S 0) autotrophically and mixotrophically in the presence of yeast extract.Autotrophic oxidation of elemental sulfur is relative weak.The comparison of ferrous iron and pyrite oxidation between strain MLY and A10 Thiobacillus ferrooxidans,strain indicated that MLY is one time faster than A10.
