Objective To explore the correlation between nurses' job burnout and social support and the source of job stress. Methods 138 doctors and 162 nurses from 4 general hospitals were investigated by different questionnaires. The nurses were investigated by Maslach Burnout Inventory(MBI),perceived social support scale(PSSS)and Chinese nurse job stress source scale. While the doctors only underwent investigation using Maslach Burnout Inventory (MBI).The results were collected and analyzed. Results The MBI results showed that the scores of emotional exhaustion and non-humanity were apparently higher, while the score of sense of working achievement was lower in nurses than those in doctors. The level of job burnout in nurses was higher than that of doctors with statistical difference. The score of social support was lower and the score of source of job stress was higher in nurses with increased level of job burnout than those with decreased level. Conclusion The status of nurses' job burnout should cause the attention of nursing managers. Prompt and selective measures should be adopted to improve the psychological health of nurses.

Objective To investigate the influence of social support on work-family conflict and psychological control ability of nurses. Methods 126 women nurses from four general hospitals by the method of random cluster sampling were divided into two groups according to the scores of the social sup-port scale(SSRS). Nurses with score lower than 35 were set as low social support group(totally 38 nurses), nurses with score higher than 45 were named as high social support group(46 nurses).The two groups were assessed by SSRS, work-family conflict scale (WFCS) and IPC respectively. The results underwent stati-s-tical analysis with t test, χ2 test and Pearson correlation analysis. Results The age and nurses' work-ing age in high social support group were significantly higher than that of the low social support group, the to-tal score of WFCS,the time,pressure and behavior score of subscales in high social support group were sig-nificanfly lower than that of the low social support group. The internality was higher, while the power-ful others and chance were lower in high social support group than those of low social support group. SSRS was negatively correlated with all factors of WFCS, positively correlated with internality factor of IPC, neg-atively correlated with powerful others and chance factors of IPC. Conclusions The nurses with high SSRS have low work-family conflict score and strong psychological control ability, so we should strengthen the social support of nurses.

Cancer-testis antigens (CTAs) are protein antigens with normal expression restricted to adult testis and yet are aberrantly activated and expressed in a proportion of various types of tumor tissues. The expressions of CTA correlate with tumor staging, histopathological subtype, recurrence and metastasis in nonsmall cell lung cancer. CTAs are immunogenic in lung cancer patients and have a good prospect in lung cancer Immunotherapy.

Objective To explore the application value of color Doppler ultrasound in diagnosis of intrahepatic artery aneu-rysms.Methods Thirty-six cases of intrahepatic artery aneurysm was diagnosed by color Doppler ultrasound.And the data were analyzed retrospectively.Results In the 36 cases of hepatic artery aneurysm,1 7 cases were located in the left lobe of liver,13 cases were located in the right lobe of liver,and 6 cases were located in the left and right hepatic lobe.A total of 27 cases were solitary, 6 cases were 2 aneurysm,and 3 cases were 3 and above aneurysm.Maximum was 28 mm×27 mm,and minimum was 8 mm×7 mm. There are 3 cases with mural thrombus.Liver oval cystic echo free zone was found by two-dimensional ultrasonography.The bound-ary was clear.The wall was smooth and thin.The rear echo was strengthened.The pulsatile red,blue single color flow signal(n=1 5)or vortex like red and blue color flow signal(n=21)were showed by color Doppler ultrasonography.The hepatic artery blood flow velocity spectrum was 12-29 cm/s,and resistance index was 0.60-0.68.Conclusion Color Doppler ultrasonography was the preferred imaging methodology of early screening and diagnosis of intrahepatic artery.

Diabetic macular edema (DME) is thickening retina with two disc diameter,which is the leading cause of blindness in diabetic retinopathy patients.The initial studies demonstrated that laser treatment of DME prevented further visual deterioration but did not improve visual acuity.Although glucocorticoid slow-release system can extend the time of effective drug concentration,to help glucocorticoid better carry out its biological effect,further studies are needed to warrant their safety due to increasing intraocular pressure and cataract progression.Novel studies identifying the presence of vascular endothelial growth factor (VEGF) in the eye with DME allowed for the development of an alternative anti-VEGF therapy,which revolutionized the management of DME by not only preventing vision loss,but also improving overall vision.Anti-VEGF therapy is becoming the first-line treatment of DME.However,present treatment modalities including anti-VEGF for DME had limitations,which build on the current understanding of DME pathogenesis.Further in-depth study of the development and outcome of DME is needed to optimize the therapeutic schemes,based on objective and scientific observation of treatment response.Finally we need to fully utilize the public health services and clinical management resources for diabetic patients,to prevent the visual impairment of DME before its occurrence.

Objective To observe changes in hippocampal network electrical activities in electroacupuncture regulation of abnormal cardiovascular activities and explore the central mechanism of the regulation. Method Experimental rats were randomized into three groups: normal urethane anesthesia without electroacupuncture (n=15), urethane enhanced deep anesthesia (n=9) and normal anesthesia plus anal canal pressurization (n=15). Femoral arterial pressure, cardiac electricity, hippocampal field potentials and cellular discharge were recorded in the three groups. The normal anesthesia group did not receive intervention measures. The other two groups received acupuncture intervention after successful induction of abnormal blood pressure. Result In rats with normal urethane anesthesia, sleep-like periodic hippocampal electrical activity occurred with periodic cardiovascular activities and theta oscillations was corresponding to increased heart rates. In rats with deep anesthesia and hypotension, theta oscillations appeared in hippocampal network with increased blood pressure and heart rates after electroacupuncture (P<0.001). Anal canal pressurization induced increases in blood pressure and heart rates and caused theta oscillations in hippocampal network. During that time, electroacupuncture could still activate theta-related cells, reduce blood pressure and decrease heart rates (P<0.001). Conclusion Theta oscillations in hippocampal network are involved in the bidirectional regulating effect of electroacupuncture on abnormal cardiovascular activities.

Objective To investigate the efficacy of procaterol and montelukast on lung function in children with moderate persistent asthma.Methods 86 children with moderate persistent asthma from January 2014 to December 2014 in our hospital were studied,and according to the random number table method,they were divided into the control group and the observation group,43 cases in each group.The observation group was treated with procaterol combined with montelukast,the control group was treated with procaterol.The cough relief and disappearance time,the improvement of pulmonary function after treatment,the clinical effect and the control of asthma after one month of the two groups were compared.Results After treatment,children cough relief and disappeared time of the observation group was significantly shorter than the control group (t =4.418 5,3.784 4,P =0.000 0,0.000 3).After treatment, the pulmonary function was found to improve the situation of the observation group being good than the control group, PEF,FVC,FEV1 ,FEV1 /FVC predicted values were significantly higher than the control group (all P <0.05).The total effective rate of the observation group (93.00%)was significantly higher than 74.40% of the control group (u =2.223 2,P =0.026 2).After one month of treatment,the basic control rate of the observation group(88.37%) was significantly higher than 67.40% of the control group(u =2.386 6,P =0.017 0).The incidence rate of adverse reactions of the observation group (6.98%)was significantly lower than 51.16% of the control group(P <0.05). Conclusion Procaterol combined with montelukast in the treatment of children with moderate persistent bronchial asthma can improve clinical efficacy,safety,and improve symptom control rate,it is worthy of promotion.

Thirty-one children suffered from speech retardation were found to have normal hearing level through ABR and/or acoustic immittance tests. Some of them were further checked by psychiatrists and pediatricians. The results demonstrate that among reasons for speech retardation in children,autism and mental retardation are important factors that can not be ignored. A-mong children with unclear diagnosis .some harmful factors were found on themselves and in surroundings. We emphasize that for children with speech retardation,not only hearing disorders,but also other factors should be considered.
