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 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 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 investigate the accuracy and efficiency of hand-held echocardiography (VSCAN) used by intensivist for the diagnosis and treatment decisions in emergency consultation for patients getting worse at risk of life-threatening setting in non-ICU ward.Methods A prospective study in acutely deteriorated patients needed the intensivist for emergency consultation in general wards was carried out.The consultation process was executed as follows:(1) The intensivist established an initial diagnosis based on medical history,physical examination and laboratory findings,and assessed the hemodynamics and the cause of acute respiratory failure and cardiac arrest according the documented information.The data recorded as control group (Pre-VSCAN) for comparison with the later available data in subsequent analysis.(2) Problem-based ultrasound examination was performed with VSCAN.For patients suffered cardiac arrest,the FEEL protocol was used to find the potential cause of cardiac arrest such as pericardial tamponade and massive pulmonary embolism screened.For the other patients,a simplified eFATE or BLUE-plus protocols were used based on clinical requirement.With the findings of ultrasound examination the intensivist established an final diagnosis and identified the hemodynamics and the lung pathologies.The consultation advice was then provided to the attending doctors of the patient.The intensivist kept the records of echo results,final diagnosis and consultation advice as data of study group data (Post-VSCAN).The response of the treatment and outcome were followed up.Two attending ICU doctors analyzed these data and judged the correctness of Pre-VSCAN and Post-VSCAN based on the response to treatment and the outcome.Results Ninety patients were finally included in statistical analysis.Sixteen (17.8％) cases,40 (44.4％) cases,29 (32.2％) cases and 5 (5.6％) were consulted for acute circulation dysfunction,acute respiratory failure,both reasons and cardiac arrest,respectively.Compared to pre-VSCAN,VSCAN verification can significantly improve the accuracy of the diagnosis (81.1％ vs.58.9％,P =0.001),assessment of hemodynamics (78.3％ vs.52.2％,P =0.009) and can find more accurate judgment of acute respiratory failure (71.0％ vs.43.5％,P =0.001).Conclusion The hand-held echocardiography used by intensivist is valuable for the diagnosis and the assessment of cardiopulmonary status in case of request for emergency consultation in general wards.

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.

ObjectiveTo explore the relation of heart rate variability (HRV) in neonatal asphyxia with myocardial injury.MethodsContinuous electrocardiographic monitoring by 24-hour Holter recordings was performed in 53 neonates with asphyxia and 40 healthy newborn.The difference of HRV with sinus rhythm was analyzed.Time-domain indexs included standard deviation of R-R intervals (SDNN) ; standard deviation of all mean 5-minute R-R intervals (SDANN) ;standard deviation of all R-R intervals for all 5-minute segments of 24 hours (SDNNindex ) ;root mean squared successive difference (rMSSD) ;percent of NN50 in the total number R-R intervals ( PNN50 ).Results( 1 ) Maximum heart rate,minimum heart rate and average heart rate of 24-hour Holter in healthy newborn were faster than those in newborn with neonatal asphyxia ( P ＜ 0.05 ).And the heart rate was faster in newborn with mild neonatal asphyxia than that in newborn with serious neonatal asphyxia ( P ＜ 0.05 ).(2) SDNN,SDANN of HRV index analysis showed significantly difference between healthy newborn and asphyxia newhom ( P ＜ 0.05 ).There were no difference of SDNN,SDANN,SDNNindex,rMSSD and PNN50 between mild and serious neonatal asphyxia (P ＞ 0.05 ).No significant differences of SDNNindex,rMSSD and PNN50 were found among three groups.ConclusionMyocardial injury caused by neonatal asphyxia can lead to damage of cardiac autonomic nevous and affect heart rate changes.The degree of myocardial injury is related to the degree of neonatal asphyxia.
