Chinese Journal of Postgraduates of Medicine 2014;37(18):9-11
Objective To study the effect of sevoflurane or propofol/remifentanil general anesthesia undergoing gynecological surgery.Methods A total of 80 patients scheduled for selected gynecological surgery were divided into sevoflurane group or propofol/remifentanil group by random digits table method and 40 cases in each group.The induction of anesthesia was conducted with midazolam,propofol,sulfentanil,and rocuronium.After tracheal intubation,anesthesia was maintained with sevoflurane in sevoflurane group,and with propofol/remifentanyl target-controlled infusion in propofol/remifentanil group.Bispectral index was monitored in each group,and which was maintained 40-60.Blood pressure and heart rate was observed.At the end of operation,all anesthetics were discontinued,and the time of consciousness recovery,tracheal extubation,orientation was recorded.The incidence of agitation,nausea and vomiting within 24 h after surgery and the use of rescue drugs such as epinephrine,atropine or urapidil was recorded.Results No statistically significant difference was observed with respect to the time of consciousness recovery,tracheal extubation,orientation between two groups (P > 0.05).The use of atropine and epinephrine in sevoflurane group was lower than that in propofol/remifentanil group [7.5%(3/40) vs.22.5%(9/40),20.0%(8/40) vs.32.5%(13/40)],and there was significant difference(P < 0.05),and the use of urapidil in sevoflurane group was higher than that in pmpofol/remifentanil group [22.5% (9/40) vs.2.5% (1/40)],and there was significant difference (P < 0.01).There was no statistically significant differences with respect to the incidence of agitation,nausea and vomiting within 24 h after surgery between two groups (P >0.05).Conclusion Propofol/remifcntanil and sevoflurane both provide satisfactory anesthesia for gynecological surgery.

3.Recent Progression in the clinical application of Permanent cardiac pacemakers
Chinese Journal of Tissue Engineering Research 2007;11(40):8213-8216
OBJECTIVE:TO summarize the newest clinical application of permanent cardiac pacemaker, and introduce the relationship between the therapy efficacy and mechanism.DATA SOURCES: Related papers were searched in Pubmed from January 2000 to December 2006 with the terms of "pacemaker,application",and the language of paper was limited to English,at the same time,related papers were searched in WangFang Database with the same terms and the language of paper was limited to Chinese.STUDY SELECTION:The papers relevant to the newest large-scale clinical trial about the cardiac pacemaker were primarily collected.Exclusion criteria:repetitive studies.DATA EXTRACTION:A total of 203 pieces of papers related to the newest clinical application of cardiac pacemaker were collected,among which,30 pieces accorded with the inclusion criteria.DATA SYNTHESIS:The pacemaker can simulate the normal myocardium cell's function pacing and conducting the rhythm. Consequently it can substitute the abnormal myocardium cell to ensure the sequence and completeness of the cardiac pacing and conducting system,the natural electrophysiological activity,and the efficiency of the cardiac ejection and blood supply.The clinical application is not only for single bradycardia, but also for cardiac electric failure, cardiac electric turbulence,and some heart diseases without cardiac electric abnormity.With pacemaker miniaturization,digital signal processing, improved diagnostics and endocardial electrograms, modern pacemakers are able to offer a sophisticated therapeutic and diagnostic platform for the patients with refractory symptoms.CONCLUSION:The pacemaker can simulate the normal myocardium cell's function pacing and conducting the rhythm.It therapy for congenital heart disease.
4.Analysis of allergen skin test results in 1124 patients with allergic rhinitis in the junction of Guangdong and Guangxi provinces.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2014;28(3):170-174
OBJECTIVE:
To investigate the characteristics and influence factors of sensitization hy allergens in patients with allergic rhinitis in the junction of Guangdong and Guangxi provinces.
METHOD:
One thousand one hundred and twenty-four patients who were diagnosed with allergic rhinitis hy clinical history and symptoms underwent a skin prick test. The percent of allergens with positive skin response and Multiple Allergens Positive Scores were recorded, and their influence factors, included age, gender and test period were evaluated.
RESULT:
The percent of top three inhalant allergens with positive skin tests were as follow: dermatophagoides pteronyssinus (77.0%) ,dermatophagoides farina (77.1%), blattella germanica (42.3%); the percent of top three ingested allergens with loositive skintests were as follow: crab ( 39.5%), shrimp (31.1%), ribbonfish (10.8%). The average Multiple Allergens Positive Score was (3.6 +/- 2.7). The percent of allergens with positive skin response and Multiple Allergens Positive Score of different allergens changed as age, gender and text period changed, and the changing trend of them was accordant. The percent inhalant allergens with positive skin tests in dermatophagoides pteronyssinus, dermatophagoides farinae and cat fur in different gender showed a significant difference.
CONCLUSION
Acarine allergens were the most common allergens in patients with allergic rhinitis in the junction of Guangdong and Guangxi provinces. The percent of allergens with positive skin response and the severity of multiple allergy were influenced by age, gender and text period. The severity of multiple allergy can be measured by Multiple Allergens Positive Score.

7.Effects of SDZ on LOVO Cell Line and the Expression of E-Cadherin and N-Cadherin
China Pharmacy 2007;0(36):-
OBJECTIVE:To investigate the effects of SDZ on LOVO cell line and the expression of E-Cadherin and N-Cadherin. METHODS: The apoptosis of SDZ on growth of LOVO cells was observed under electron microscope and inverted microscope. The expression of E-Cadherin and N-Cadherin treated by SDZ were detected by RT-PCR. RESULTS: SDZ promoted the apoptosis of LOVO cell lines and increased the expression of E-Cadherin,however,it did no effect on the expression of N-Cadherin. CONCLUSION: SDZ can enhance the intercellular adhesiveness and degrade the capability of infiltration and metastasis of tumor cells.
8.Analysis of 813 Cases of ADR Reports in a Hospital during 2013-2015
China Pharmacy 2017;28(17):2359-2362
OBJECTIVE:To investigate the characteristics and regularity of adverse drug reaction (ADR) in a third grade class A hospital,and to provide reference for rational drug use in clinic. METHODS:A total of 813 cases of ADR reported to Na-tional ADR Monitoring by the hospital during 2013-2015 were summarized and analyzed retrospectively in terms of age,gender,route of administration,drug type,organs or systems involved in ADR,clinical manifestation and outcome. RESULTS:Among 813 cases of ADR,there were 391 male (48.09%) and 422 female (51.91%). Patients aged more than 60 were with high inci-dence of ADR,involving 347 cases(42.68%). Among routes of administration,most ADR cases were caused by intravenous ad-ministration,involving 747 cases (91.88%). Among all drug types,the number of ADR cases caused by anti-infective drugs was the most,involving 382 cases(46.99%);cephalosporins took up the highest proportion,being 38.22%(146 cases). Organs or sys-tems involved in ADR were mainly skin and its appendants,involving 434 cases (53.38%). CONCLUSIONS:ADR monitoring should be strengthened for elderly patients receiving anti-infective drugs intravenously so as to reduce the occurrence of ADR and guarantee medication safety.
