Objective: To investigate the effects of nursing process on the support of early enteral nutrition(EEN) in severely burned patients.Methods: EEN was carried out in 97 patients with severe burns by retention of naso-gastric(intestinal) feeding tube and continuous drip of nutritious fluid.97 patients were divided by different periods into two groups:group A and group B.The nursing process was used in group B.A series of parameters including the bearing to enteral nutrition,the patients′ nourishment,the occurance rate of complication,the time of wound healing and the cure rate were observed and analysed.Results: The bearing to EEN of the patients in group B was better than that in group A(P

Objective To determine the relationships among the balance between nurse's work and family,the nursing practice environment and demission intention.Methods A total of 351 nurses were recruited from 5 hospitals in Zhengzhou by convenience sampling method.They were investigated using the Questionnaires for balance between nurse's work and family,the nursing practice environment and demission intention.Results The mean scores of the balance between nurse's work and family,the nursing practice environment and demission intention was (3.09±0.46),(2.86±0.48),(2.51 ±0.57).The predictors of demission intention of nurses were rational allocation of resources,age,work disturbs family,and family promotes work.Conclusions The levels of the balance between nurse's work and family,the nursing practice environment and demission intention are all in the medium.The balance between nurse's work and family and the nursing practice environment have direct positive influence on demission intention.

Objective:To explore the influence of trimetazidine (TMZ)combined traditional routine drugs on progno-sis of patients with cardiac syndrome X.Methods:A total of 80 patients with cardiac syndrome X were randomly and equally divided into routine treatment group and TMZ group (received TMZ 20mg,three times/d based on routine medication).Both groups were treated for 12 weeks.Patients of two groups received treadmill exercise test and car-diac function examination before and after treatment,and the results were statistically compared.Results:Com-pared with routine treatment group after treatment,there were significant rise in total exercise time [(7.90±1.45) min vs.(9.35±1.70)min]and the time ST segment depressed 1mm [(5.30±1.43)min vs.(6.78±2.00)min], and significant reduction in ST segment depression extent [(0.89±0.30)mm vs.(0.61±0.20)mm],P <0.05 all;for cardiac function,there were significant rise in stroke volume [(67.99±11.77)ml vs.(74.05±7.58)ml]and left ventricular ejection fraction [(50.13±11.05)% vs.(56.02±9.52)%]in TMZ group,P <0.01 all.Conclusion:TMZ can significantly improve prognosis of patients with cardiac syndrome X.

Objective To investigate the mid-term efficacy of percutaneous laser disc decompression(PLDD) for patients with lumbar disc herniation.Methods Between May 2001 and December 2006,a total of 122 patients with simple lumbar disc herniation underwent PLDD in our hospital.Under local anesthesia,the operaiton was performed using a laser diode with the patients in supine position.A C-arm X-ray system was employed to guide the surgery.Results The patients were followed up for 6 to 60 months(mean 36.5 months).Accroding to the MacNab Criteria,60 patients achieved excellent outcomes,39 were good,15 were fair,and 8 were poor.The rate of exellent and good outcomes was 81.1%(99/122).No patient had postoperative complications.Conclusions PLDD is effective and safe for patients with simple lumbar disc herniation.The cases recover quickly after the operation,because the procedure is minimally invasive.

AIM:To study the effects and mechanisms of ethanol on chloride channels in poorly differentiated nasopharyngeal carcinoma CNE-2Z cells.METHODS:The effect of ethanol on the cell growth was analyzed by MTT as-say.The technique of whole-cell patch-clamp was used to detect the chloride current .The characteristics of the chloride current were analyzed by using the chloride channel blockers .The siRNA technique was used to analyze the molecular basis of the ethanol-sensitive chloride channels .RESULTS: Under isotonic conditions , the background current was weak and stable.Ethanol at concentrations of 0.17~170 mmol/L activated a chloride current in a concentration-dependent manner (an inverted U-shape), with a maximum effect at the concentration of 17 mmol/L.The currents showed obviously outward rectification and were susceptible to extracellular hypertonicity and the chloride channel blocker , 5-nitro-2-(3-phenylpropyl-amino) benzoic acid ( NPPB) .ClC-3 siRNA obviously decreased the currents activated by ethanol .CONCLUSION:Ex-tracellular ethanol induces chloride currents through activating the ClC-3 chloride channels .

Objective　To analyze the current situation and influencing factors of health-care seeking delay among pulmonary tuberculosis patients in Qingpu District of Shanghai from 2011 to 2022, and to provide a scientific basis for tuberculosis prevention and control. Methods　The data of pulmonary tuberculosis patients in Qingpu District of Shanghai from 2011 to 2022 was collected through the China Tuberculosis Information Management System to describe the distribution and change trend of the delay in health-care seeking. Univariate analysiswas performed using the chi-square (χ²) test, and the time trend of rates was tested with the trend chi-square (trend χ²) test. Multivariate logistic regression model analyzed the influencing factors of the delay in health-care seeking. Results　From 2011 to 2022, there were 3 488 cases of pulmonary tuberculosis in Qingpu District, with 1 438 patients experiencing health-care seeking delay. The median (quartile) number of days of delay was M (P25, P75) = 10 (2, 24) days, and the rate of health-care seeking delay was 41.23%. The annual rate of health-care seeking delay fluctuated between 33.88% and 50.45% from 2011 to 2022, with statistically significant differences between different years (χ²=38.355, P<0.001), and an upward trend in the health-care seeking delay rate was observed from 2020 to 2022 (χtrend²=13.290, P<0.001). Multivariate logistic regression analysis showed that compared to male, those under 25 years old, with local household registration, and detected through health check-ups, females (OR=1.21, 95%CI:1.04-1.41), those aged 45 to <65 (OR=1.36, 95%CI:1.06-1.75), intra-city migrants (OR=1.35, 95%CI:1.09-1.68), inter-provincial/overseas migrants (OR=1.50, 95%CI:1.23-1.83), and patients who directly sought medical care (OR=3.52, 95%CI:2.27-5.47), transfer treatment (OR=2.07,95%CI：1.31-3.25), referral (OR=2.16, 95%CI:1.36-3.44), follow-up (OR=3.07, 95%CI:1.74-5.44) patients with pulmonary tuberculosis were more likely to delay health-care, and the differences were statistically significant (P<0.05). Compared to sputum-positive patients, those with sputum-negative tests (OR=0.76, 95%CI: 0.59-0.97) were less likely to experience delayed health-care, and the difference was statistically significant (P<0.05). Conclusions　Health-care seeking delay of pulmonary tuberculosis patients is relatively common in Qingpu District of Shanghai. Corresponding intervention measures should be adopted for risk factors and key populations to further improve the health-care seeking delay.

Objective To assess the feasibility of double phase subtraction angiography with second generation (128-slice )dual-source CT in low dose Flash spiral scan mode for the evaluation of cerebral vessel,compared with dual-energy subtraction angiogra-phy.Methods 60 patients underwent double phrase CT angiography were divided into group A (n = 30,with Flash spiral scan mode),group B(n=30,with dual-energy scan mode).The signal-to-noise ratio(SNR),the contrast-to-noise ratio(CNR)and the av-erage radiation of double phrase subtraction images were measured in two groups,respectively.The double phase subtraction images quality were graded by 2 independent readers on a 5-point scale(5=excellent)in double-blind,according to various degrees of the re-sidual bones,the vessel displayed and luminal integrity,respectively.Differences between two groups were analyzed by Mann-whit-ney test and t test.Results The double phrase image SNR showed no difference to both two groups(P >0.05).The image CNR of arterial and venous phase in group A were higher than that of group B(40.89±8.89 and 40.27 ±9.90 in group A vs 35.28 ±8.43 and 34.89±8.66 in group B;P <0.05)respectively.There were no singnificant difference in the bone removal image scores of doub-le phase and in the vessel image scores of venous phase to both two groups respectively(P >0.05).The vessel image scores of arterial phase were higher in group A than that of group B(4.93±0.25 vs 3.87±0.97;P <0.05).Some internal carotid in the base of skull has not good luminal integrity in group B.The mean dose length product (DLP)in group A was lower than that of group B,with a 39 percent reduction[(226±5.69 )mGy/cm vs (368 ± 21.35 )mGy/cm,P < 0.05 ].Conclusion With the roughly similar image quality to dual-energy double phase subtraction angiography,the cerebral vessels can be assessed using dual-source CT subtraction angiography in Flash spiral scan mode and a lower radiation dose.

Objective To explore the relationship among job satisfaction,work engagement and organizational citizenship behavior (OCB) of nurses.MethodsA total of 497 nurses in 5 tertiary level general hospitals in Zhengzhou selected by convenience sampling,were investigated by Minnesota satisfaction questionnaire,nurses' OCB scale and the Utrecht Work Engagement Scale.ResultsThe scores of job satisfaction,work engagement,OCB were (78.63±11.34),(38.31±7.78),(106.33±10.26) respectively.Nurses' job satisfaction was positively correlated with work engagement and OCB(r=0.529,0.481,P<0.01),and work engagement was positively correlated with OCB(r=0.456,P<0.01).The job satisfaction and work engagement had a positive prediction effect on OCB(changed R2=34.8%),and work engagement played a partial moderation effect between job satisfaction and OCB,the mediating effect accounted for 30.77% of the total effect.ConclusionManagers should take measures to improve job satisfaction and work engagement to promote OCB of nurses.

Objective: To explore the correlation between serum level of high molecular weight adiponectin (HMW-ADPN) and arteriosclerosis. Methods: Clinical data of 87 middle-aged and aged people living in home, who underwent health examinations in Xiangya second hospital from Jan 2011 to Dec 2011, were collected. According to carotid-femoral pulse wave velocity (cf-PWV) = 9 m/s, they were divided into group A (cf-PWV<9 m/s, n=21) and group B (cf-PWV≥9 m/s, n=66). Blood pressure, blood lipid, blood glucose etc. were measured and compared between two groups. Results: Compared with group A, there were significant rise in blood pressure, levels of low density lipoprotein cholesterol, triglyceride and total cholesterol, and significant reduction in levels of high density lipoprotein cholesterol (HDL-C), serum total ADPN and HMW-ADPN in group B, P<0.05 or <0.01. Multiple regression analysis indicated that serum HMW-ADPN (B= - 4.469，P=0.011), total ADPN ((B= - 3.965，P=0.012), HDL-C（B= - 2.077，P=0.015) and systolic blood pressure levels (B= 0.045，P=0.045) were independent predictors of cf-PWV. Conclusion: Serum high molecular weight adiponectin and total adiponectin levels may be protective factors against arteriosclerosis. Its role in predicting occurrence and development of arteriosclerosis is worthy of further study.
