Objective To investigate the observation and nursing for patients with atria] fibrillation (AF)after left atrial linear ablation surrounding ipeilateral pulmonary veins (PVs). Methods Thirty patients with persistent AF underwent left atrial linear ablation surrounding ipsilateral PVs guided by CARTO electroanatomic mapping system and double Lasso catheters technique. The end point of ablation was defined as absence of all PV spikes after isolation and bidirectional conduction block between left atrial and PVs. Results After a median of (245±65)days of follow-up, twenty-one patients were free of AF. Eight patients subjected recurrent atrial tachyarrhymias, including 5 typical AFL, 2 atrial taehycardia and 1 paroxysmal AF. Two patients with persistent AF remaining PV spikes in left superior PV failed to be translated to sinus rhythm. Nine patients underwent repeated ablation and 8 of them were free of atrial taehyarrhythmia after (192±92) days follow-up. Total success rate after two procedures was 92.8%. Conclusions Nurses should perform effective care according to the symptom of patients before, during and after ablation procedure and relieve the patients from pain.

Compared to portal vein embolization and traditional two-stage hepatectomy,associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) can induce the proliferation of liver rapidly,concomitantly with high incidence of complications and mortality in the perioperative period.The feasibility and safety have been improved gradually as the improvement of technology and the accumulation of experience.But it is still controversial on its efficacy for malignant tumors,especially with insufficiency of medium-and long-term out-comes.The mechanism of rapid proliferation induced by ALPPS needs more studies with further steps.

AIM and METHOD: Human endothelial nitric oxide synthase (eNOS) gene was transfected into human phagocytic cell U937 and the effects of gene transfer on cytokines and cAMP production were observed. RESULTS: A functional eNOS was stably expressed in transfected U937 cells, but NO release was undetectable in intact transfectants. However, eNOS gene expression upregulated tumor necrosis factor - a release and downregulated interleukin - 10 and cAMP production in either presence or absence of NOS inhibitor N? - monomethyl - L - arginine. CONCLUSION: The function of tranfected eNOS gene product showed cellular speciality. The effector molecule that changed the produced pattern of cytokines and cAMP in phagocytic cells seems not likely the nitric oxide.

Laparoscopic cholecystectomy(LC),as a new minimal invasive technical method,is now the golden standard treatment for symptomatic gallbladder stone.The article is to discuss the principle during course of deveiopping LC should be followed on the view of medical ethics. The doctors' high sense of responsibility,the strict laparroscopic surgical training,the cooperation between doctors and the right attitute to converting to an open cholecystectomy must be the importat factors to develop LC smoothly.

OBJECTIVE:To provide approaches and avenues for the Chinese drugs preparations manufacturers in the GMP depuratory authentication.METHODS:The features and difficulties in the GMP depuratory authentication of the Chinese drugs preparations such as the optimizing of depuratory regulations,the determination of the acceptable standards,the choice of testing methods,clarification of expiration date and re-authentication were analyzed.RESULT&CONCLUSION:The depuratory regulations of the manufacturing facilities for the Chinese drugs preparations must be optimized.

OBJECTIVE:To provide references for the improvement of our country's current Good Manufacturing Practice(GMP).METHODS:In consideration of GMP standards and problems in its implementation,the system,customers,suppliers,business leaders and documentation etc.were analyzed.RESULTS&CONCLUSION:Problems in the GMP standards has influenced the practice of GMP.In order to improve and optimize the GMP standards,it was recommended that process system be integrated to make the design quality in conformity with the manufacturing quality,open quality management system be established,business leader's leading effect be emphasized and clear and universal documentation system be established.

Objective To know about the pre-deployment training curriculum of PLA peacekeeping medical units. Methods Methods including questionnaire survey, spot investigation and seminars were used to collect the information of pre-deployment training curriculum from 260 peacekeepers (from 5 military area commands) and 14 international students from Second Military Medical University; their attitudes toward the curriculums were also collected. Microsoft Excel software, SPSS18.0 and Likert statistical method were used to process the collected data. Results The 9 most popular courses included related knowledge, laws and regulations, and principles of battlefield wound first-aid, etc; the most recognized courses included oral English, related knowledge, and laws and regulations; and courses like water and electricity support had a comparatively lower recognition level. Conclusion More efforts should be made on constructing modularized courses, practicing individualying training, intensifying language training and developing novel teaching mode pre-deployment training curriculums for PLA peacekeeping medical unit.

OBJECTIVE: To develop a method for the determination of ethanol extracts content of Pogostemon cablin (Blanco) Benth. using near-infrared spectroscopy. METHODS: The ethanol extracts contents of 139 samples were determined by the method of ethanol cold-soak extraction. Near-infrared spectrograms were obtained, then multiplicative signal correction, first derivative method and Savitzky-Golay filter method were used to process the spectrograms, at last the calibration model of ethanol extracts content was established by partial least squares regression analysis method. RESULTS: The correlation coefficients, root-mean-square error of calibration, root-mean-square error of prediction and root-mean-square error of cross-validation of the calibration model of ethanol extracts content were 0.98958, 0.590, 0.623 and 0.97518, respectively. CONCLUSION: The method is stable, accurate, and can be used to predict ethanol extracts content of Pogostemon cablin (Blanco) Benth. rapidly.
