Objective To investigate the applicative effect of cardiopulmonary resuscitation in pre-hospital care of emergency pa-tients with cardiac arrest and provide the basis for pre-hospital care of cardiac arrest.Methods Selected 93 cases of cardiac arrest in January 2011 to May 2013 occurred out of Hainan Province Nongken Sanya Hospital,including 51 cases of cardiopulmonary resusci-tation of pre hospital rescue as the study group,42 cases of the application of artificial compression cardiopulmonary resuscitation as control group.Compared blood oxygen saturation,oxygen and carbon dioxide partial pressure and blood pressure changes,CPR time,spontaneous breathing recovery time and the recovery of the function of two groups.Used chemiluminescence method to detect NSE,NT-proBNP,cTnI and H-FABP.Results The two groups of patients with blood oxygen saturation,oxygen and carbon diox-ide partial pressure showed no statistical difference(P>0.05);the DBP and SBP levels of the study group were significantly higher than the control group(P<0.05);the study group CPR time and spontaneous circulationtime were significantly higher than that in control group(P<0.05).Two groups of intraoperative heart rate,respiration,blood pressure and oxygen saturation had no signifi-cant difference(P>0.05).Study group of patients with spontaneous breathing recovery,the restoration of spontaneous circulation, survival is greater than 24 h and rehabilitation discharge rates were significantly higher than the control group(P<0.05).There was no significant difference in the serum levels of NSE,NT-proBNP,cTnI immediately,H-FABP recovery in spontaneous circula-tion(P>0.05);after 24 h,NSE,NT-proBNP,cTnI,H-FABP levels in study group were significantly lower than those in the control group(P<0.01).Conclusion The application of cardiopulmonary resuscitation in patients with cardiac arrest before salvage can ef-fectively shorten the recovery time of CPR patients and spontaneous circulation time,reduce the damage to heart,brain,lung and other organs,improve the success rate of cardiopulmonary resuscitation,worthy of clinical application.

Two-component signal transduction system (TCS) exists extensively in prokaryotic cell ,which plays a key role of regulation in the growth ,differentiation ,metabolism ,virulence ,persistence ,and pathogenicity .PhoPR two-component signal transduction system ,as one of two-component systems ,is the most basic and the most importantly sensitive to the envi-ronmental changes and makes corresponding certain reaction system adapt to changes in the host microenvironment .Therefore , PhoPR TCS which is an important regulatory system of Mycobacterium tuberculosis (MTB) to adapt to environmental change has been increasing concern ,even PhoPR TCS is becoming the new front-burner issue in the pathogenesis of M TB regulation of research .

0.05). Conclusion Isthmus is an essential structure to determine the size of femoral component. The dimension of isthmus correlates fairly well with the size of femoral stem. As a measurement to choose the appropriate femoral implant in total hip arthroplasty, the isthmus-method has the similar accuracy as the common templating.

ObjectiveThe purpose of this study was to investigate the effect of health education on the recovery of insight in schizophrenic patients. MethodThe insight of patients in health education and control groups was assessed by SAUMD and BPRS bdfore and 4, 8, 12 weeksafter trentment. ResultThe recovery of insight of health education group was significantly different from control group after treatment. Theinsight scores was significantly related to major symptom, cultural level and disease course. ConclusionThe health education for schizoprenicpatients was important in recovering insight and illness and promoting patients go back to society early.

During cell apoptosis,a series of characteristic changes occur in the cell configuration and,according to recent findings,in the cytoskeleton as well,including degradation,condensing and maldistribution of the cytoskeleton reticular formation.Through investigations of the biological activity and function of the cytoskeleton protein,the dynamic changes of the cytoskeleton during cell apoptosis and related regulatory factors,we found that the change of configuration is based on that of the cytoskeleton during cell apoptosis,which suggests that we can achieve the purpose of curing tumors and other diseases by inducing cell apoptosis through changing the cytoskeleton configuration.

The core event of cell proliferation is DNA replication and cell division. DNA topoisomerase type Ⅱ plays an important role in this process.As a cell proliferating marker,DNA topoisomerase type Ⅱis caught great attention. The authors review the recent research of NDA topoisomerase type Ⅱ and its value evaluated as a cell proliferating marker.

OBJECTIVE To ensure safe operation of medical equipment through raising procurement staffs′ awareness of safety and quality control in the process of purchasing medical equipment and exerting fine control of safety and quality throughout procurement. METHODS To sum up regulations,rules and ways on the safety and quality control at all links in the process of purchasing.RESULTS The acceptance rate of quality inspection of introduced medical equipment was 100% and the operating rate of equipment for the annual working hours was 95%.In 2002,our work together with other departments work in our hospital passed the proof of ISO9000. CONCLUSIONS They can not keep hidden safety perils of medical equipment outside the gate of the purchasing and can not ensure the safe operation of medical equipment and its vital role in every medical activity,unless purchasing staffs observe all purchasing regulations and rules and exert fine control of safety and quality of the purchasing.

Objective To study the clinical effect of Xianglian in Mixture (Mixture of Nutgrass Galingale Rhizome and Golden Thread) in treatment of premature beat accompanied anxiety disorder.Methods Totally 100 patients of premature beat accompanied anxiety disorder were randomly assigned into two groups.The 50 patients in the treatment group were treated with Xianglian Mixture and the 50 in the control group were treated with Rytmonorm and Alprazolam for 4 weeks.The TCM symptom scores,premature beats in Holter,scores of Hamilton anxiety scale (HAMA) and the therapeutic effect on all these indices of both groups were observed.Results After treatment,the TCM symptom scores,premature beats in Holter,scores of HAMA of both groups were decreased significantly (P0.05).Conclusion Xianglian Mixture can reduce premature beats and relieve anxiety as well.

[Objective]To observe the growth pattern of oligodendrocyte precursor cells(OPCs) in the primary culture from neonatal rat cerebral cortices and study the methods of cell culture and isolation in order to obtain purified OPCs for the experiments of cell transplantation.[Method]The mixed glial cells from the cerebral cortices of 48-hour-old Sprague-Dawley(SD) rats were cultured in vitro.Until 9-10 days in vitro OPCs were isolated and purified by the shaking process and differential adhesion,and then continued OPCs culture in the defined medium.The growth pattern of OPCs in vitro was investigated by contrast phase microscopy and OPC s were further identified with the immunocytochemical techniques.[Result]The distinct stratification of OPCs and astrocytes developed around 9-10 days in primary culture.At this point,the OPCs scattered on the top of the monolayer astroctyes and the soma of most OPCs typically appeared oval or round with two or three processes.The purity of the isolated OPCs reached 95% and these OPCs further developed into the mature oligdendrocytes which were immunoreactive to the specific antigen of oligodendrocyte lineage cells,Oligo2.[Conclusion]OPCs separated from the cerebral cortices of neonatal SD rats can be maintained as immature precursor cells in culture,and OPCs are able to be purified by shaking and differential adhesion under the condition of appropriate cell stratification.

Objective To study the effects and mechanisms of major immune nutrients and to introduce the progresses of clinical applications about enteral immunonutrition.Methods The related literatures about the effects and clinical applications of enteral immunonutrition were reviewed.Results Infection rate can be reduced and the hospitalization can be shortened as a result of the improved nutritional status and immune competence of patients which can be enhanced by reasonable enteral immune nutrition.Most of the patients suffering from serious diseases can benefit from enteral immunonutrition,such as gastrointestinal cancers,post-transplantation complications,chronic liver disorders,acute pancreatitis and so on.However,as a new nutrition therapy,the clinical use of enteral immunonutrition in critically ill patients is still controversial.Conclusions Enteral immunonutrition plays an important role in the nutritional support of patients with serious diseases,such as gastrointestinal cancers,organ failures.However,much work remains to be done.
