Objective To explore the master degree on knowledge of forensic medicine of clinical medical students who had been educated with it,and their suggestion to the course,to adjust the teaching reform in forensic medicine in medical college for nationalities. Methods This investigation was made by anonymous questionnaire in clinical medical students (224),who had accept forensic medicine course. Results The knowledge of forensic medicine of most clinical medical students in medical college for nationalities was good,yet it was not enough to them; and the present teaching method was too simple. Conclusion We should teach forensic medicine definitely for clinical medical students of medical college for nationalities with plentiful pictures and videos.

In recent years ,the diffusion magnetic resonance imaging in the study of breast cancer is in-creasing,which including diffusion weighted imaging ,diffusion tensor imaging ,intravoxel incoherent motion ,and diffusion kurtosis imaging .The emergence and development of these technologies can be noninvasive quantitative evaluation of breast tumors from the molecular level .The researchers pay more and more attention to the applica-tion of breast cancers diagnosis and differential diagnosis ,therapeutic effect ,prognosis evaluation and so on .This paper reviews the progresses of the above four technologies in the use of the breast cancer .

Objective To analyze the effect of different medical insurance payments on medical expenses so as to provide some suggestions for Guangdong Provincial Department of Offsite Medical Insurance Administration in its future policy-making.Methods An statistic analysis was conducted of medical expenses among patients who chose different medical insurance payments and their average length of stay.Results Medical expenses and average length of stay were statistically different among patients who chose different payments.Conclusion The medicare reimbursement′s inclusion of prevention and diagnosis should be recommended to establish a flexible referral system, reinforce the payments reform and increase the efficiency of social security funds.

Objective To analyze the histopathology of patients with atypical squamous cells of undetermined significance (ASCUS),and provide evidence for further classification and clinical treatment of ASCUS.Methods The histopathology of cervical biopsy specimens from 249 patients with ASCUS diagnosed by liquid-based cervical cytology examination was analyzed retrospectively. Results Among the 249 ASCUS patients, the proportion of patients with inflammation was 34.14% (85/249), morphological change by human papillomaviral infection was 19.28%(48/249), CIN I was 32.53%(81/249),CIN II was 8.84%(22/249),CIN III was 3.21%(8/249), infiltrating squamous cell carcinoma was 1.20%(3/249),and endometrioid adenocarcinoma was 0.80%(2/249) . Conclusion It is very important to to further definitude the diagnosis of ASCUS, because a certain proportion of cervical cancer and precancerous leisions woud be confirmed.

Objective To study the contraction of artery in colonic cancer.Methods Arteries in the cancer part and the cancer ambient part of patients with colonic cancer,the concentration-contractile curves induced by the noradrenaline(NA),sarafotoxin 6c(S6c) and endothelin-1(ET-1) in cumulative application were recorded by myograph.Results The E_(max) and pD_(2)of normal colonic artery contraction induced by NA were(97?19)% and(5.94)?0.17.The E_(max)and pD_(2) of contraction in colonic cancer artery was lower than that in cancer ambient artery(P0.05)).Conclusion The ?-adrenoceptor and ET_(A) receptor are main receptors mediating contraction in colonic cancer artery.

Objective To explore the effect and method of the theory teaching of general practice course for eight-year program of clinical medical students. Methods The course of General Medicine was set up for 87 students from two grades in their fourth school year. All of them attended a closed-book exami-nation when they finished the lectures. The satisfaction rates, necessity and the suggestion of teaching and assessment were collected from the questionnaire. Results The examination results of the two grade students were (80.92±7.26) and (83.76±5.75); The satisfaction rate was 40.2％ (35/87); Necessity of the courses was between 3.6 to 4.1 (5-point-Likert-scale). The way of teaching method students chose was dif-ferent by course content. Conclusion The theory teaching of general practice course for eight-year program of clinical medical students needs more reform from curriculum designing, teaching methods, faculty train-ing and evaluation methods.

Cognitive estimation is a process in which correct answers can be reasonably estimated by relevant information,instead of be obtained in a direct manner.The cause of cognitive estimation disorder is relevant to executive function and frontal lobe damage.The assessment of cognitive estimation disorder is mainly based on texts such as CET,BCET and TKS,and clinical symptoms are also taken into consideration in this assessment.Future studies include several aspects.Firstly,more efforts should focus on improving diagnostic standard and assessment tools and expanding the related studies.Secondly,it is necessary to focus on the specific brain areas of clinical patients with cognitive estimation disorder,and to strengthen the clinical rehabilitation of cognitive functions.

? AlM: To evaluate the efficacy of the method of vitrectomy combined with posterior sclera reinforcement for retinal detachment due to macular hole in high myopia.
?METHODS:From January 2012 to December 2013, in 45 eyes of 45 high myopic patients with retinal detachment due to macular hole, 28 eyes were in group A of vitrectomy with posterior sclera reinforcement and 17 eyes were in group B of vitrectomy. Preoperative examinations included visual acuity, intraocular pressure, indirect ophthalmoscopy and OCT were performed. ln follow - up 6 to 12mo, postoperative examinations of visual acuity, OCT were performed and effects of retinal reattachment and macular hole closure were compared between the two groups.
?RESULTS: ( 1 ) Postoperative examinations: visual acuity was 1. 19±0. 39 in group A and 1. 51±0. 34 in group B. The differences were statistically significant(P<0. 05). (2) The retinal reattachment rate was 100% in group A and 88. 24% in group B. There was no statistical significance between them(P>0. 05). (3) The macular hole closure rate was 82% in group A and 53% in group B. The differences were statistically significant(P<0. 05).
? CONCLUSlON: The treatment of vitrectomy with posterior sclera reinforcement is safe and feasible, which could improve visual acuity and increase the rate of macular hole closure in treating retinal detachment due to macular hole in high myopia.
