Objective To analyze the efficiency of mifepristone combined with norethindrone in treating dysfunctional uterine bleeding of peri-menopause. Methods 56 patients with dysfunctional uterine bleeding of peri-menopause were randomly divided into two groups, the study group(30 cases) and the comparision group(26 cases). The patients in the study group were treated with mifepristone in small doses combined with norethindrone. And the patients in the comparision group were treated only with norethindrone. Before treating, all the patients were observed and measured symptom of dysfunctional uterine bleeding, blood routine,the function of liver and ren.the en-dometrial thickness and pelvic by ultrasonography. Through hysteroscopy or uterine curettage of diagnosis, en-dometriums were measured by pathology. Results 26 cases in the study group were evaluated as effective,2 cases as obviously effective,and 2 cases as no effective. In the comparision group, 10 patients were evalutated as effective,8 patients as obviously effective,8 patients as no effective. The total effective rates of study group was significantly higher than those of comparison group(P

Objective To explore the nursing cooperation in use of lung inflation system for video-assisted thoracoscopic surgery (VATS) for spontaneous pneumothorax. Method The key nursing points in nursing 42 patients with spontaneous pneumothorax undergoing VATS were analyzed. Results The operations were all successful. One patient contracted lower left atelectasis but it was cured after the tracheal tube was re-adjusted. On day one, there were two cases of gas leakage during thoracic closed drainage:one was of diffuse pulmonary bulla, and the gas leakage stopped on the second day; In the other cases, the gas leakage stopped 2 days after the tube was withdrawn by 3cm probably because the drainage tube was inserted too deep at the beginning. 6-30 months follow-ups showed no recurrence of pneumothorax in the operated site. Conclusions The lung inflation system is safe during VATS for spontaneous pneumothorax. Careful preoperative preparation of the equipment and skillful nursing cooperation at all procedures are critical for the success of VATS.

Objective To evaluate the teaching effects of case introduced method based on picture archiving and communication system (PACS) system in medical imaging course.Methods Totally 148 students (2009 grade) majored in five-year clinical medicine from Xiangya Medical College were divided into 10 groups; the 10 groups were taken randomly as control group (n=75) and experimental group (n=73).Control group used traditional teaching methods (film teaching) while experimental group used case introduced method based on PACS system.Effects of teaching between were evaluated by questionnaire and test.x2 test was used to compare students' theoretical test scores,with α level =0.05.Results Based on results of questionnaires,more students in experimental group than in control group hold that case introduced method based on PACS system can achieve the purpose of teaching,improve interests in learning,and strengthen the mastery of knowledge.Test scores showed that the percentage of students scored 90-100 and 80-89 (respectively 14％,75％) in experimental group was significantly higher than that in control group (respectively 5％,66％) (x2 =17.932,P=0.000).Conclusions Application of case introduced method based on PACS system in medical imaging course not only improve students' motivation to learn and their clinical ability,but also allow teachers to find and correct shortcomings of students timely,therefore,it is worth promoting.

Objective To investigate the prevalence and charateristics of carotid atherosclerosis among healthy middle-aged people of community. Methods Totally 1930 subjects aged 50 years and above were selected randomly from 10027 participants recruited during Phase 3 of the Guangzhou Biobank Cohort Study (GBCS).Common carotid artery intima-media thickness (CCA-IMT) and carotid plaques (CP) were measured by B-mode ultrasonography using ALT HDI 3000 mainframe with a high-resolution. Results The prevalences of CCA-IMT and CP in men were higher than women [41.5％(400/963)vs.16.2 (157/967),34.1％ (328/967) vs.13.8％ (133/967),both P＜0.001].The prevalence of CCA-1MT was higher with age increasing in either men or women in groups of 50-yrs,60-yrs and 70-79 yrs (all P＜0.001).The most of CP was cankerous spot (37.8％),secondly hard spot (24.9％),soft spot (22.1％) and the prevalence of flat spot was lowest (15.2％).The number of CP was not significantly different between the left and right side (51.0％ and 49.0％).The most common location of CP was bifurcations of carotid arteries (61.7 ％),next the common carotid artery (21.0％) and internal carotid artery (ICA) was lowest (17.3 ％).The prevalence of CP was 44.4％ (83/87) in women aged 50- yrs,it was higher than that in men 20.9％ (108/517).However,the prevalence of CP was 79.1％ (409/517) in men aged more than 60 yrs,higher than that in women (55.6％). Conclusions The carotid atherosclerosis is commonly encountered disease in the male elderly,and the most of CP was cankerous spot in bifurcations of carotid arteries

Objective To investigate the teaching effect of‘index’teaching method used in practical teaching of the medical imaging.Methods A total of 178 medical undergraduates were selected this study,113 clinical medical students using‘index’teaching method were taken as experimental group while others 65 anesthesia medical students using traditional teaching method as control group.The teaching effect of‘index’teaching method was evaluated quantitatively and qualitatively by practical test and questionnaire survey.Results The test scors of experimental group were(80.3±16.5),obviously higher than those of(71.3±25.8)in control group(P＜0.05),especially instudents with low scores.Conclusion The new teaching method had obvious advantages in culturing the thinking of imaging diagnosis and in improving the ability to solve clinical practical problems,the‘index’teaching method was more effective than traditional teaching method.

Objective To explore the prevalence of diabetes and hyperlipidemia in cerebral infraction patients with hypertension and look into the rates of awareness, treatment and control. Methods Blood pressure, blood glucose and blood lipids were measured in 238 cerebral infraction patients with hypertension. Meanwhile, the rate of awareness, treatment and control of hypertension, diabetes and hyperlipidemia were investigated by questionnaire. Results Among 79.41％of the patients had abnormal blood pressure and cerebral infaction on admission, the rates of awareness , treatment and control of hypertension were 74.79％, 67.23％, 20.59％. 10.11％of them never took antihypertensive drugs in spite of their awareness of hypertension. 32.35％ of the patients were combined with diabetes, the rates of awareness, treatment and control were 79.22％, 62.34％, 12.99％respectively, and among them 21.31％never tookantidiabetic drugs in spite of awareness of diabetes. 81.51％ of the patients were combined with hyperlipidemia, the rates of awareness, treatment and control were 23.20％, 6.70％, 1.55％respectively, and among them 71.11％never took lipid-lowering drugs with awareness of high blood lipid. Conclusions 79.41％ of the incidence of cerebral infraction was related to abnormal blood pressure. 32.35％cerebral infarction patients with hyperlipdemioa are complicated with hypertension diabetes;81.51％are complicated with 28.57％cerebral infraction patients with hypertension were complicated with diabetes and hyperlipidemia as well, but the rate of awareness, treatment and control were relatively low. In order to improve the secondary prevention, we should pay more attention to the stroke risk factors, and help make the individualized medicine-taking plan to improve the control rate.

Objective To explore the effects of telephone follow-up on patients with sub-clinical hypothyroidism. Methods Of 120 patients who were diagnosed as sub-clinical hypothyroidism between January, 2014 and June,2014, 60 were included in control group and 60 were assigned in observation group by a random number table. Patients in control group received routine check-up and treatment protocols according to their condition, in contrast, patients in observation group had extra telephone follow-up. Patients′symptoms, the degree of goiter, thyroid ultrasound examination, thyroid function and thyroid peroxidase antibody (TPOAb), and other indicators were compared in the two groups after 12 weeks intervention. Results After the intervention, both groups had an improvement in slow reactions, chills, skin changes, body mass increase, etc. After invention, thyroid stimulating hormone and TPOAb in observation group were statistically different from those in control group [(1. 955 ± 1. 633) vs (2. 875 ± 3. 025) mIU/L, (204. 500 ± 825. 500) vs (438. 500 ± 1065. 250) IU/ml] (Z=2. 539,1. 451;P<0. 05). Patients with thyroid enlargementⅢdegrees reduced from 29 cases to 14 cases in observation group, which was better than that in control group (χ2 =2. 199, P<0. 05). Thyroid ultrasound results were similar between the two groups (χ2 =0. 043, P >0. 05). Conclusions Telephone follow-up intervention is helpful to improve the symptoms of patients with sub-clinical hypothyroidism, alleviate goiter and promote thyroid function back to normal.
