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]

Uveitis is a kind of refractory blinding eye diseases.Noninfectious uveitis is an important part of uveitis,which is thought to be an autoimmune disease,and systemic immunosuppressive therapy is usually required to prevent visual loss.As a selective T-cell inhibitor,cyclosporine A is one of the most widely used immunosuppressants,and has obvious therapeutic effect on many kinds of uveitis.Cyclosporine A combined with glucocorticoid,other immunosuppressants or biological agents can improve the therapeutic effect and reduce the side effects.Recently,the inhibitory effect on glucocorticoid-resistant Th17 cells and topical application of cyclosporine A,show its advantage and potential in the treatment of noninfectious uveitis.

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.

Objective:To investigate the inhibitory effect of recombinant mutant human tumor necrosis factor(rmhTNF-?)combined with cisplatin(DDP)against transplanted Lewis lung carcinoma(LLC)in mice,and to explore the related mechanism.Methods:LLC cells were subcutaneously inoculated into C57BL/6 mice at the right axilla and the mice were randomly divided into 4 groups:sodium chloride(control group),DDP group,rmhTNF-? group,rmhTNF-? plus DDP group.On the 7th day after inoculation the diameter of the tumor reached 0.6 cm;the corresponding agents were intratumorally injected for 3 d.All mice were sacrificed 1 d later and the tumors were obtained,weighed,and the tumor inhibitory rate was calculated.Flow cytometric analysis was used to examine cells apoptosis and cell cycle.Expression of survivin mRNA was examined by RT-PCR.Results:(1)The tumor inhibitory rates of the DDP plus rmhTNF-? group(36.61%)was significantly higher than those of the DDP group(17.12%)and rmhTNF-? group(15.83%,P

Conclusion The efficiency of the management of medical equipment can be evaluated by using this method.

Objective To establish a new method to identify and analyze Qingdai Powder and its composition.Methods X-ray Diffraction with Fourier pattern was used.Results The standard X-ray diffraction with Fourier pattern and characteristic diffraction peaks of Qingdai Powder and its composition drugs were obtained.Conclusion The powder X-ray diffraction method can be used as a simple and convenient method for the identification of Qingdai Powder and its composition drugs.

AIM:To observe the effect of lidocaine to the activation of NF-?B and apoptosis in human neutrophils(PMN)in vitro.METHODS:Human PMN were divided into five groups:control group(0.9% sodium chloride);TNF-?(200 ng/L);TNF-?+lidocaine(1.0 mmol/L);TNF-?+lidocaine(2.0 mmol/L),and TNF-?+ lidocaine(4.0 mmol/L).The expression of NF-?B subunit p65 mRNA in the nuclear and I-?B mRNA in the cytosol extracts were analyzed by Western blotting,after co-incubation for 3 h and the content of p65 protein were observed by RT-PCR.PMN apoptosis was detected on flow cytometry after co-incubation 12 h and 24 h.RESULTS:The expression of NF-?B mRNA was significantly decreased and the expression of I-?B mRNA was markedly increased in lidocaine groups(P

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.

The proposal to promote the commercialization of new insect-resistant GM cotton,GM corn and other major products in 13th Five Year Plan on National Science and Technology Innovation ,has put forward a test to the government's ability to manage GM crops cultivation.Only a few species of GM crops,not including food crops,have been commercialized in China,we lack experience in GM crops cultivation management.Taking USA,where the farmers cultivate huge areas of GM crops,as a comparison object,the examination and approval procedures before cultivation,GM crop growers' obligation of the management,the methods to reduce mingling of GM crops and non-GM crops are compared.And concludes that the differences in legal status of GM crops,the intellectual property regime and labeling regulation,the ability of relative stakeholders to implement segregation measures and bear loss lead to different regulation on GM crops cultivation management in USA and China.The government combine the domestic current situation of the agricultural environment in our country,and focus on substantial risk in the safety management of GM crops in cultivation management is advised.The competent department of agriculture,researchers and seed traders should work together to help guide growers to avoid the economic disputes due to mingling and reduce the impact on the ecological environment.
