The objective structured clinical examination (OSCE)system of our school was established by designing graduate examination with OSCE, by constantly improving and enhancing the science, objectivity, utility of OSCE. The guiding role of OSCE in clinical teaching, clinical practice and medical licensure examination was explored by analyzing the examination results and questionnaire of students.

OSCE is a new method which has strong objectivity for the evaluation of clin-ical skills examination.According to the actual situation of our college,we chose medicine sta-tion of OSCE to assess the level of the clinical skills of the clinical graduates.

The transcript assembly is essential for transcriptome studies trom next-generation sequencing data. However, there are still many faults of algorithms in the present assemblers, which should be largely improved in the future. According to the requirement of reference genome or not, the transcript assembly could be classified into the genome-guided and de novo methods. The two methods have different algorithms and implementation processes. The quality of assembled transcripts depends on a large number of factors, such as the PCR amplification, sequencing techniques, assembly algorithm and genome character. Here, we reviewed the present tools of transcript assembly and various indexes for assessing the quality of assembled transcripts, which would help biologists to determine which assembler should be used in their studies.

ObjectiveTo explore the significance and the scheme of OSCE ( Objective structural clinical examination ) applied in clinical resident training and examination. MethodsOSCE were adopted to train and evaluate residents clinical skills. 180 residents were trained through OSCE for two weeks.Then a test on clinical skills of the residents by OSCE was conducted after training. 172 questionnaires of evaluation on the training effect were collected and analyzed. ResultsWith regard to the training and examination of clinical skill, 96.51％ residents considered that it was helpful for clinical work, 98.26％ considered that it would make their operation more standandized. ConclusionThe training through OSCE is an important way to improve and evaluate clinical skills of residents and may be widely applied.

Objective To study the cerebral energy metabolism changes of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) through hydrogen magnetic resonance spectroscopy examination (1 HMRS ) and its relationship with partial pressure of oxygen / carbon dioxide tension.Methods Totally 13 cases of AECOPD patients and 10 cases of age-matched healthy people underwent HMRS examination.The ratios of n-acetyl-aspartate(NAA)/creatine(Cr),choline (Cho)/Cr,myo-inositol(MI)/Cr of parieto-temporal and occipital areas of brain were detected.Blood gas analysis were also used to detect partial pressure of oxygen (PaO2) and carbon dioxide (PaCO2).Results NAA / Cr of parieto-temporal and occipital areas of brain (1.32±0.12,1.48±0.12) were lower in AECOPD group than those in control group (1.45±0.11,1.58±0.10) (P＜ 0.05),MI/Cr (0.23±0.07,0.30±0.11) were also decreased compared with control group (0.40±0.14,0.46±0.12) (P＜ 0.01),while Cho/Cr of parieto -temporal and occipital areas of brain between the AECOPD group and control group showed no significant difference (P＞0.05).NAA/Cr of parieto temporal and occipital areas of brain were positively correlated with PaO2 (r=0.46 and 0.44),and MI/Cr of these areas of brain were also positively related with PaO2 (r=0.63 and 0.50),but MI / Cr of parieto tempora was negatively correlated with PaCO2 (r =- 0.472). Conclusions Cerebral metabolite changes may occur in AECOPD patients,and this has relationship with hypoxia and carbon dioxide retention.

?AlM: To investigate the clinical characteristics and influencing factors of chronic renal failure ( CRF) patients with dry eye, and to provide clinical reference.?METHODS:Sixty-one cases (122 eyes) of patients with CRF ( CRF group ) and 61 cases ( 122 eyes ) of healthy persons ( control group) were carried out on Schirmer ▏test ( S▏t ) , break-up time of tear film ( BUT ) , corneal fluorescein staining ( FL) , test results of two groups were compared and related factors of dry eye in CRF patients were analyzed.?RESULTS: The results of S▏t and BUT in CRF group were lower than that in the control group (P<0. 05). The proportion of tear secretion reduce in CRF group ( S▏t<10mm/5min) was 49. 2% ( 60/122 ), which was higher than that in the control group ( 10. 0%, 12/122 ), the difference was statistically significant ( X2 = 45. 39, P <0. 05). The percentage of instability of tear film in CRF group (BUT≤10s) was 75. 4% (92/122), which was significantly higher than that in the control group (27. 0%, 33/122) (X2=57. 1, P<0. 05). The positive rate of corneal FL was 37. 7% (46/122), which was higher than that of the control group (10. 7%, 13/122), there was a statistically significant difference (X2= 24. 34, P<0. 05).?CONCLUSlON:CRF patients with a decrease in tear film stability and tear secretion are susceptible population to dry eye, clinically should be paid attention to the treatment.

Multimedia teaching and SimMan,which is a portable and advanced patient simulator for team training,were used to develop a new course for the medical students of grade four. This course was named "SimMan clinical techniques training". The course of Sim-Man clinical techniques training can help students comprehend truly all kinds of cases in clinical practices,improve their capabilities of clinical thoughts and clinical techniques,and it makes fine basis for their clinical practices in the hospitals.

Objective To Study wheather the endogenous arginine vasopressin(AVP)is involved in the effect of oxotremorine(a muscarinic receptor agonist)-induced hypothermic response.Methods Core temperature and motor activity were monitored in undisturbed rats using radiotelemetry.Effect of AVP V1 antagonist on oxotremorine(OXO)-induced changes in body temperature and motor activity were observed in the rats.Results Administration of OXO led to a marked hypothermia.Core temperature recovered to basal levels at 4 hours after OXO administration.AVP V1 antagonist blocked markedly the hypothermia effect of OXO.Conclusion The AVP V1-receptor antagonist block the hypothermic effect of OXO,which suggests that OXO-induced hypothermia is mediated by AVP releasing.

BACKGROUND:On the basis of thorough debridement, homochronous anterior or staging posterior fixation has been a standard scheme for spinal tuberculosis. Numerous studies confirmed that above approach has obtained good effects, but the anterior approach has some disadvantages, such as complex anatomic structure, great trauma, relatively more complications, and difficult operation and fixator implantation. OBJECTIVE:To observe spinal stabilization and deformity correction in patients with single-segment thoracic/lumbar spinal tuberculosis after posterior debridement and interbody fusion. METHODS:Clinical data of 36 patients with single-segment thoracic/lumbar spinal tuberculosis undergoing one-stage posterior debridement and interbody fusion in the Guangxi Yulin Orthopedics Hospital of Integrated Traditional Chinese and Western Medicine from January 2008 to January 2012 were retrospectively analyzed. There were 2 cases in single T11/12 segment, 4 in T12/L1 segments, 6 in L3/4 segments, 22 in L4/5segments and 2 in L5/S1 segments. Of them, 24 patients suffered from different degrees of spinal nerve injury. At 6, 12 and 24 months after surgery, al patients were folowed up. Bone graft fusion, kyphosis correction, functional recovery of the spinal cord and complications were observed. RESULTS AND CONCLUSION:Al patients were folowed up for 24-38 months. Cobb angle of kyphosis and spinal stenosis rate were significantly improved at 2 years after treatment (P < 0.05). The lumbar back pain symptoms were significantly improved in final folow-up (P < 0.05), with an intervertebral fusion rate of 100%. No lesion residue and recurrence, correction loss, fixation loosening or displacement was found. These results demonstrated that in patients with single-segment thoracic/lumbar spinal tuberculosis, posterior debridement and interbody fusion can effectively reconstruct spinal stabilization, correct deformity, and promote the functional recovery of spinal nerves.
