Objective To analyze the psychosocial influential factors on job burnout and their interaction models in first aid medical staff.Method A survey was carried out concerning job burnout status,job stress,job overload,work-family conflict,overall job satisfaction,coping styles and social support in 504 first aid medical staffs,by which to seek the psychosocial influential factors of job burnout status and explore their interaction models using stepwise multivariable regression and path analysis.Result (1) The stepwise multivariable regression on the job burnout showed that job overload,work stress,work-family conflict,overall work satisfaction and negative coping style were the key social-psychological influential factors in job burnout(F =90.562,P =0.001).(2) The path analysis showed that the job overload was the major event caused the work stress,and work stress played a direct and indirect roles in the level of job burnout in first aid medical staff,and the work-family conflict and overall work satisfaction was disposition factors of job burnout with direct actions and indirect actions.The negative coping style was an intermedium link between work stress and job burnout.Conclusion Decrease of work intensity and change of bad coping styles can be effective on job burnout in first aid medical staff.

Patients with malignant tumor are easy to be complicated with venous thrombosis,which is the second leading cause of death for patients with malignant tumor.The mechanism of tumor thrombus forma-tion is related to tumor type,treatment,metastasis,heredity and tumor itself.Evaluating the risk of venous thrombosis in patients with cancer and providing targeted preventive anticoagulation measures for high-risk patients have important significances for improving the quality of life and prolonging the survival period of pa-tients with cancer.

OBJECTIVE: To investigate the application and the clinical effect of nasal endoscope in styloid process truncating operation. METHOD: Dividing 66 patients into nasal endoscope group and control group randomly, and then observe them. Nasal endoscope group were cured with nasal endoscope during the styloid process truncating operation and the control group were treated with the routine method of intraoral path. All the operations were executed by the same person. Observation index included the following aspects: the length of the truncated styloid process, the operation time, intraoperative bleeding, postoperative pain and pain degree, inflammatory reaction of raw surface and rehaemorrhagia. RESULT: Compared with the control group, the length of the truncated styloid process of nasal endoscope group were longer and the operation time had no significant differences. The intraoperative bleeding of intraoperative bleeding group were (85.0 +/- 35.0)ml and in control group were (95.0 +/- 40.0)ml. There are no significant differences between the result. Nasal endoscope group also had the advantages of fewer aches and less inflammatory reaction of raw surface. Both of the team had no rehaemorrhagia. CONCLUSION nasal endoscope can truncate a longer styloid process in styloid process truncating operation and is effective to relieve pain, and ease inflammatory reaction, it's a safe mini-trauma operation.

The necessity to carry out student-oriented teaching of Medical information retrieval and use course in medical postgraduate was analyzed according to its theory followed by an elaboration on its module setting, course management methods, course examination forms and teachers.

Objective:To explore the genetic polymorphism of cytochrome P450 enzyme 17(CYP17) and its relationship with the pathogenesis ofpolycystic ovary syndrome(PCOS).Methods:A total of 260 patients with PCOS of uyhan and han nationality in Xinjiang,who were admitted to Chinese Medicine Research Institute of Xinjiang Uygur Autonomous Region from January 2015 to February 2017,were chosen as PCOS group;the other 237 healthy fertile women,who were examined in the outpatient department during the same period,were chosen as control group.The CYP17 gene polymorphism in the two groups of subjects was detected by the restriction fragment length polymorphism polymerase chain reaction (PCR-RFLP) technique;the distribution of alleles and gene frequencies was compared between the two groups;combining with its clinical data,the relationship between CYP17 gene polymorphism and the pathogenesis of PCOS was analyzed.Results:Body Mass Index(BMI) and Follicle-stimulating hormone(FSH) levels in the PCOS group were lower than those in the control group;Luteotropic hormone(LH),Testosterone(TES) and LH/FSH levels in the PCOS group were higher than those in the control group,and the differences were statistically significant (P＜0.05).The frequencies of A1A1,A1A2,and A2A2 of CYP17 gene in the PCOS group were 34.62％,41.92％,23.46％,respectively,compared with 34.18％,43.88％,21.94％ in the control group,the difference was not statistically significant (P＞0.05).The allele frequency of A1 and A2 in the PCOS group were 55.58％,and 44.42％ respectively,compared with 56.12％ and 43.88％ in the control grouP,the difference was not statistically significant (P＞0.05).There was not statistical significance in FSH,LH and LH/FSH levels of different CYP17 genotypes in the PCOS group (P＞0.05).There was statistical significance in BMI level A2A2＞A1A2＞A1A1 and TES level A2A2＜A1A1＜A1A2 in the PCOS group (all P＜0.05).The BMI,FSH,LH,TES and LH/FSH levels of different CYP17 genotypes in the control group were not statistically significant (P＞0.05).Conclusion:CYP17 gene-34bp T/C nucleotide polymorphisms is a common base replacement in the population,which is not significantly related to the pathogenesis of PCOS.

Compressed oxygen in diaphragm-type compresesor currently used can easily cause fire,ex- plosion or damage.The reason for the causes was analysed and requirment for the oxygen was put forward. Proceed from the three aspect:selection of lubricating oil;replace of material quality and alarm for the di- aphragm broken;the problems of diaphragm-type compressor were finally settled.

Objective: To investigate the therapeutic effect of intensive glycemic control on patients with early diabetic nephropathy. Methods: A total of 41 type 2 diabetes patients who developed microalbuminuria were divided into two groups randomly. Patients in Group A received intensive glycemic control and the blood glucose in Group B was regularly controlled. Glycemic monitoring and control were followed for 12 weeks to observe the changes of microalbuminuria in both groups; meanwhile the levels of serum lipids and coagulation indices were also recorded. Results: The urine albumin excretion rate (UAER) in Group A decreased significantly from (47.91±13.86)mg/24 h to (35.31±14.56)mg/24 h after 12 weeks (P<0.05), and this decrease was significantly greater than that in Group B. However, Group B had no significant difference in UAER decrease [(48.93 ± 13.32)mg/24 h to (40.48 ± 19.62)mg/24 h, P>0.05]. The decrease of triglyceride (TG) and low-density lipoprotein cholesterol (LDL cholesterol), and the increase of high-density lipoprotein cholesterol (HDL cholesterol) showed no significant differences (P>0.05). And the level of plasma fibrinogen (FIB) showed no significant decrease after 12 weeks, either (P>0.05). Conclusion: Intensive glycemic control reduces the level of microalbuminuria and may ameliorate the progression of early diabetic nephropathy.
