Objective:To investigate the false alarm rate of electrocardiogram monitor, and to develop methods to exclude interference. Methods:A total of 52 patients in emergency room in hospital in March 2014 were in the control group. The frequency and causes of false alarms of the electrocardiogram monitor were recorded. At the meantime, the improvements were analyzes. A total of 52 patients in emergency room in hospital in May 2014 were chose to be the experimental group. The frequency and causes of false alarms of the electrocardiogram monitor were recorded after some improvements. Results: In control group, the total of alarms rate were 5376 times, including 2208 times of false alarms. The false alarm rate was 41.07%. While in the experimental group, there were 2634 alarms, including 798 times of false alarms. The false alarm rate was 30.29%. Compared to the control group(x2=25.77, P<0.05). It was statistically significant difference. Conclusion:Intervention on Mindray electrocardiogram monitor can reduce the false alarm rate, help to improve the efficiency of nurses and ensure safety to patients.

Objective To research into the major influenced factors of psychological health of medical students and to discuss some rational measures.Method We reasonably analyzed the influenced factors of students psychological health in a Medicine University via instituted questionnaire and quantitative survey.Result Although there exists gender difference,the main influenced factors of psychological health are attributed to employment pressure,self-contempt,sense of frustration, poverty and emotional reverse.Conclusion Each university and each medical student should commit themselves to the education of psychological health.

ObjectiveTo investigate the effects of ARB or/and β-blocker in treatment of dilated cardiomyopathy(DCM).Methods95 cases with DCM were randomly divided into 3 groups.ARB group(A,32 cases) was treated with Irbesartan,150 mg/d without adverse drug reaction and then to 300 mg/d weekly; β-blocker group( B,30cases) was treated with Bisoprolol,1.25 mg/d without adverse drug reaction and then to maximal dose weekly; combination group( AB,33 cases) was treated with Irbesartan and Bisoprolol to maximal dose which patients were able to tolerate.The 3 groups were observed for a period of 12 months.ResultsComparing with pretreatment,the results of 6min walk,LVEDd,LVESd,LVEF were improved significantly( all P ＜0.05).There were no significant differences between A group and B group(P ＞0.05),but the differences between combination group and A group or B group were significant( P ＜0.05 ).ConclusionEffect of ARB combined with β-blocker was better than that of ARB or β-blocker alone in treatment of DCM and well tolerated.

Objective To investigate the effect of tourniquet compression on axonal transport in sciatic nerve of rats.Methods Twenty-four 12-week old male SD rats weighing 250-300 g were randomly divided into 4groups according to the duration of tourniquet compression(n=6 each):1,2,4 and 12 h.The tourniquet was applied to the middle 1/3 of thigh.In each animal whether the left or right thigh was compressed was determined by a flip of coin.The tourniquet was released for 10 min after every hour of compression.A 3-cm segment of sciatic nerve was removed at the end of tourniquet compression(1.5 cm proximal and 1.5 cm distal to the site of compression).Immuno-histochemistry was used to measure the expression of insulin-like growth factor-1(IGF-1)in the sciatic nerve.The ratio of average optic density of the compressed sciatic nerve to that of control was used to estimate the degree of IGF-1 accumulation.The regression equation of the interaction between the duration of compression and accumulation of IGF-1 was analyzed.Results There was significant accumulation of IGF-1 in the sciatic nerve proximal to the compressed site.The accumulation increased with the duration of compression.There was no significant accumulation of IGF-1 in the sciatic nerve distal to the compressed site.The regression equation of the interaction between the duration of compression(X)and accumulation of IGF-1(Y)was Y=0.422X+0.887.Conclusion Tourniquet compression of sciatic nerve can inhibit axonal transport.The accumulation increases with the duration of compression.

Objective To evaluate therapeutic effects of Bushen-Zhuanggu medicine extraction on bone destruction in rats bone cancer pain.Methods Rat models of cancer-induced bone pain were established by inoculating MRMT-1 cells into tibia of rats.Behavioral signs indicative of pain including 50%paw withdrawal threshold(von Frey tactile sensitivity test)and thermal withdrawal latency were observed.Pathomorphological changes of tibia were monitored with HE staining.Results In the behavioral tests,herbal medicine treatment attenuated mechanical allodynia and thermal hyperalgesia.Histological examination showed that this treatment inhibited tumor proliferation and preserved the cortical and trabccular bone structure.Conclusion Bushen-Zhuanggu medicine extraction is an anti-nociceptive and bone-preserving agent in rats of bone cancer pain.

Moot Court practice teaching is an important part of the teaching of medical and health law. Based on several years of university students' participating in moot court competition, and combined with the personal experience of the instructors and the participating students, we summed up our inexperience of medical law moot court practice teaching, and put forward feasible suggestions to professional Moot Court simulation practice teaching reform of Health Law in order to effectively improve the medical and health professional moot court practice teaching, thus implementing the law to strengthen the students practical skills trainingteaching objectives.

Objective To understand the health level of people living in county and the situation between the requirement and utilization of health service for rural residents in Chongqing as well as the main influential factors by investigating the basic condition and hospitalization expenditure. Methods Three county hospitals were included in our study: county general hospital, Chinese traditional medicine hospital, and maternal care hospital. The hospitalized patients from the three hospitals were investigated on a certain day by questionaire and the data of discharged patients in a month were collected and analyzed by SAS8.0 software. Results Factors such as the hospital type, sex, age, the cost for sickbed, diagnosis and treatment fee and so on were significantly associated with the total cost for hospitalization. Expensive hospitalization fee harms the quantity and quality of health service required by rural residents. Conclusion The utilization rate of health service by female was lower than by male in rural area. The total utilization rate of health service has been improved since the new policy about rural health service was carried out. People over 45 years old are the main consumers of health service. Peasants are still main consumers to medical organization at county level. Suitable technic of health service for county hospitals should be carried out in time.

Objective To study the CT features of cerebral infarction and the relation to blood glucose level in diabetes mellitus.Methods The CT features and relation to the level of blood glucose were retrosepectively analyzed in 41 cases of cerebral infarction diabetes mellitus.The diagnosis of diabetes mellitus was based on the WHO criteria in all cases.Results The focus of infarction located at the area of base ganglion,brain stem and thalamencephalon in 38 cases(92.7%).Multiple focus was found in 30 cases(73.2%)and there was positive correlation between focus number and the level of blood glucose.Lacuna cerebral infarction was observed in 38 cases(92.7%) and large patchy cerebral infarction in 3 cases.Brain white matter demyelination was complicated in 24 caese(58.5%).Conclusion Cerebral infarction of diabetes mellitus mainly manifestes as multiple lacuna cerebral infarction and has close relation to the level of blood glucose.
