Despite efforts to develop treatment technology for cardiac arrest (CA), CA incidence and mortality rates are still high.[1,2] A recent study of CA patients in emergency departments revealed that the incidence of CA is increasing annually, and the in-hospital survival rate of CA patients is only approximately 28.7%.[3] Echocardiography has been widely used as an important monitoring tool in critical care and helps to identify the cause of shock, monitor hemodynamics, and guide fluid therapy utilization.[4] One study reported that approximately one-third of patients underwent formal echocardiography during hospitalization in the intensive care unit (ICU).[5]

Laboratory animal science has become a main support for the development of life science and has occupied an importance place in higher medical education.The paper analyzed the characteristics and problems of laboratory animal science and proposed the ideas of applying conformational memory teaching in laboratory animal science teaching from there aspects:teaching method,teaching frame and teaching effect.These measures established the foundation for the cultivation of applied talents with comprehensive competence.

Commercialization of the doctors sector and lawyers sector, and that of medical services, sharp rise of medical disputes and its impact on healthcare services have grown into major challenges for the healthcare system in the United States where litigation is the legal way out of medical disputes at large.Anglo-American law system depends heavily on precedence as the criteria and the majority of such disputes trials are held in state courts, there is also a complete system of laws and decrees on medical disputes on the federation level.In an effort to handle medical disputes that are rising sharply in a piling-up amount, American lawyers, social organizations of arbitration and medicine, and many state courts are seeking alternative dispute resolution as a better way out for medical dispute mediation and resolution.Given the gaps between China and USA in social systems, legal systems, ,economic development, cultural background, healthcare systems and heahhcare security systems, these experiences will prove their value of reference for medical disputes resolution in China.

OBJECTIVE:To compare mental state and drug safety of puerperant underwent propofol and etomidate painless abortion after regain of consciousness. METHODS:102 puerperant underwent painless abortion were selected and randomly divided into control group and trial groups with 51 cases in each group. The control group received Propofol injection 2 mg/kg intravenous-ly,and the trial group received Etomidate fat emulsion injection 0.2 mg/kg intravenously. The changes of patient’s mental state were evaluated with Positive and Negative Emotions Scale (PANAS) before anesthesia and after regain of consciousness. The changes of HR,BP,MAP and SpO2 were observed and compared between 2 groups before anesthesia and 1,2,3 and 5 min after anesthesia. The anesthetic effect and ADR were compared between 2 groups. RESULTS:Compared to before anesthesia,positive mood scores of the trial group were increased slightly after regain of consciousness,while that of the control group were increased significantly;there was statistical significance before anesthesia and after regain of consciousness (t=9.023,P<0.05);there was statistical significance between 2 groups(t=8.367,P<0.05). Negative mood scores of 2 groups were decreased significantly af-ter regain of consciousness;there was statistical significance before anesthesia and after regain of consciousness(t=8.672,9.895, P<0.05). HR,BP MAP and SpO2 of 2 groups had no statistical significance within 5 min after anesthesia(P>0.05). The total effective rate of anesthesia in control group was 80.4%,while that of trial group was 78.4%;there was no statistical signifi-cance between 2 groups (χ2=1.273,P>0.05). The incidence of nausea,vomiting,dizziness and other ADR were similar in 2 groups,but the incidence of fantasy(39.2%)in control group was significantly higher in trial group(11.8%);there was statistical significance between 2 groups(χ2=10.120,P<0.05). CONCLUSIONS:Propofol and etomidate have good stability on the respira-tory and circulatory system,anesthetic effects are correspond to the incidence of ADR. Etomidate has a better safety. But the psy-chological status of patients in the propofol group is preceding than etomidate group.

ObjectiveTo compare of the thickness of left ventricular wall of Ang Ⅱ induced cardiac hypertrophy model in both TR3 konock-out C57BL/6 mice (TR3-/- mice) and wild type C57BL/6 mice (TR3+/+ mice) by high frequency ultrasound,combined with experimental research to discuss if TR3 take part in the process of cardiac hypertrophy.Methods26 TR3 -/- mice and 33 TR3 +/+ mice were randomized to 2 groups respectively:TR3+/+ + AngⅡ group (27 mice),TR3+/+ + PBS group(6 mice),TR3-/- + Ang Ⅱ group(20 mice),TR3-/- + PBS group(6 mice).Micro-pumps with AngⅡ or PBS were placed into the subcutaneous tissue of mice to construct hypertension model in 4 weeks.Interventricular septum enddiastolic thickness (IVSd) and left ventricular posterior wall end-diastolic thickness (LVPWd) were measured by echocardiography 2 days before operation and every week after operation until 4 weeks.Then,mice were killed and mice cardiomyocytes were isolated and detected in lab (HE dyeing test,Western blotting).Results①Echocardiography:before operation,IVSd and LVPWd was not statistically different between TR3+/+ group and TR3-/- group( P ＞0.05).1 - 2 weeks after operation,IVSd and LVPWd had peaked in both TR3-/- + Ang Ⅱ group and TR3 +/+ + Ang Ⅱ group,IVSd and LVPWd in TR3 +/+ + Ang Ⅱgroup were significantly thicker than control group (TR3 +/+ + PBS group) ( P ＜0.05),IVSd and LVPWd in TR3-/-+ AngⅡ group were slightly thicker than control group (TR3-/- + PBS group) ( P ＜0.05).Compared with TR3-/- + Ang Ⅱ group,IVSd and LVPWd in TR3+/+ + Ang Ⅱ group were markedly increased( P ＜0.05).After 4 weeks operation,IVSd and LVPWd of all 4 groups were not statistically different than that in the 2nd week.②HE dyeing test:The cell size of cardiomyocytes in TR3+/+ mice increased significantly after Ang Ⅱ treatment,while TR3-/- mice did not.③ Western blotting:Ang Ⅱ promoted TR3 expressions in TR3 +/+ mice( P ＜0.05).ConclusionsTR3 do take part in the process of Ang Ⅱ induced cardiac hypertrophy in mice and it is a key factor in this process.

OBJECTIVE:To investigate the analgesia effect of low-dose ketamine combined with sufentanil after radical sur-gery of esophageal cancer. METHODS:Totally 153 patients of pre-implementation esophageal cancer surgery were randomly divid-ed into group A,B and C. After induction of anesthesia in patients in each group,patients in group A administered sufentanil 2 μg/kg;group B were treated with sufentanil 2.5 μg/kg;group C were treated with sufentanil 2 μg/kg + ketamine 85 μg/(kg·h). Visual analog(VAS)score and Ramsay score before and after anesthesia 4,8,16,24 and 48 h,analgesia pump pressing times and inci-dence of adverse reactions in each group were observed. RESULTS:Ramsay score in 4,8 and 16 h in each group were significant-ly higher than before anesthesia,the differences were statistically significant(P<0.05),however,compared with before,there was no significant difference in the Ramsay score in 48 h among each group(P<0.05);VAS scores in each group(except for group C in 48 h) at each time point were significantly higher than before,group C

OBJECTIVE:To improve the quality standard of Shexiang qutong liniment. METHODS:TLC was used for qualita-tive identification of Resina draconis and Rehmannia. The determination of total solids and ether-soluble extracts in the preparation was detected. GC was used for the content determination of muscone:the column was Thermo-TG-WAXMS capillary column by programmed temperature,the detector was FID detector,the detector temperature was 250 ℃,inlet temperature was 200 ℃,carri-er gas was high purity nitrogen at a flow rate of 1.0 ml/min,split ratio was 5:1,and the injection volume was 1 μl. RESULTS:The TLC pots of R.draconis and Rehmannia were clear with good separation. The total solids in preparations were not less than 0.6%,and extracts were not less than 3.0%. The linear range of muscone concentration was 15.21-243.36 μg/ml(r=0.9998);RS-Ds of precision,stability and reproducibility tests were lower than 2%;recovery was 97.70%-99.63%(RSD=0.78%,n=6). CON-CLUSIONS:The established method can be used for the quality control of Shexiang qutong liniment.
