Vasovagal syncope (VVS) although is a benign disease,repeated syncope attacks can reduce quality of life in patients,in some cases,can also lead to serious body injures.Therefore,it is required and necessary to the treatment of patients with VVS.The treatment of VVS includes health education,drug treatment and non-drug treatment.

Objective:To study the clinical characteristics of children with paragonimus pericarditis.Methods:The diagnosis and treatment effect of 43 children with paragonimus pericarditis were retrospectively analysed.Results:There was diversity in the clicinal manifestations.Thirty-four cases were treated with praziquantel,pericardiocentesis,open pericardial drainage and so on.In 30 cases that were followed up,26 cases were cured and 4 cases developed pericardial constriction.Four cases with constrictive pericarditis were cured after pericardiectomy.Conclusion:The children with paragonimus pericarditis could be diagnosed early by careful asking of the case history of eating crabs,routine examination of the numbers of the acidophile in blood and pericardial effusion and paragonimus antigen intracutaneous test.It is possible to develop pericardial constriction after clinical cure in those cases that have had a long course of disease before treatment.

OBJECTIVE:To study the pharmacological actions of compound Yinshen granules(CYSG) on cerebral ischemia injuries in rats METHODS:Using an established middle cerebral artery occlusion(MCAO)model devised by Tamura,we observed infarction areas of the brain and behaviour grade of cerebral apoplexy,and calculated brain water content and brain index RESULTS:CYSG(10 0g/kg,5 0g/kg in rats)significantly reduced infarction areas,ameliorated neurological symptoms,decreased brain water content and brain index after MCAO in rats CONCLUSION:CYSG can protect ischemia cerebral injuries in rats

Chemotherapy has been the cornerstone of cancer treatment for decades. However, albeit remarkable, the response to chemotherapy is generally short-lived. With deepened understanding of cancer immunology, resurgence was recently witnessed in the field of cancer immunotherapy. Unlike chemotherapy, immunotherapy induces a relatively mild but stable response. Accumulating evi-dence reveals that apart from chemotherapy's direct cytotoxic activity, chemotherapy exerts immune-potentiating effects by increas-ing the immunogenicity of tumor cells or by disrupting the tumor-induced immunosuppression and altering the immune microenviron-ment. The latter mechanism serves as the basis for the combined use of chemotherapy and immunotherapy. In this review, we exam-ine the rationale for combinatorial therapy in accordance with the current understanding on tumor immunity and newly discovered im-mune-based chemotherapeutic mechanisms. We further discuss the available preclinical and clinical studies on the combination of chemotherapy and immunotherapy for cancer treatment. We aim to provide a framework for further research.

Objective To investigate the influence of negative emotion on patients with peptic ulcer and their cognition about self-management knowledge. Methods Zung self-rating depression scale (SDS), self-rating anxiety scale(S/IS) and self-designed survey questionnaire of peptic deer patients' gen-end knowledge were used to examine 105 peptic ulcer patients in outpatient and inpatient in the digestive department and the data were compared with those of 106 healthy people. Results The peptic ulcer pa-tients' total score of SDS and SAS, and the occurrence rate of positive symptom were obviously higher than those of healthy people. In the group of ulcer patients, we compared the data of SDS one by one, the emo-tion of patients was different when their profession was different. The difference between patients with and without anxiety in keeping emotion steady and appropriate diet was significant. 45.8%～78.1% of patients with negative emotions didn't understand the cycle of treatment, regular consultation with a doctor or com-plication. Conclusions Nurses should evaluate the emotional state of patients, establish nursing plan based on individual patients, give different nursing and education to different patient. Thus patients' general self-management knowledge and compliance can be improved, their spirit health level can be alleviated. It can also reduce incidence of the disease and prevent relapse.

Objective The purpose of this study was to evaluate the use of tracheo-oesophageal vioce prostheses after total laryngectomy.Methods Between 1995 and 1999,18 male patients ,Aged from 42 to 68,average 54.6,used Blom-singer voice prostheses after total laryngectomy.10 cases were glottic style,8 cases were subglottic style.12 patients received stage I,6 patients received stage Ⅱ voice reconstruction surgery. Results All cases were followed-up from 3 to 5 years. The success rate was 77.8%(14/18). The time with prostheses ranged from 8 to 19 months(average 12months). All failures were stage Ⅱ surgey .Conclusion Stage I voice reconstruction surgery can be performed in all total laryngectomy patients. But the indications of stage Ⅱ voice reconstruction surgery should be controlled strictly. More attention should be paid to the training of voice rehabilitation after total laryngectomy. The tracheo-oesophageal voice prostheses is an effective method to improve the life quality of the patients.

Holter monitoring remains an useful diagnostic tool in the evaluation of syncope in children if synco-pe remains unexplained after the initial examination.But it should not be used as a screening tool.Holter monitoring is recommended in children who were suspected as cardiac syncope or who had an abnormal electrocardiogram.For chil-dren with frequent syncope,Holter monitoring is highly recommended.More information can be provided with extended Holter monitoring to 48 hours if possible.Heart rate variability is probably useful in predicting head -up tilt test diagno-sis of neurally mediated syncope.

Lung cancer is the leading cause of cancer death worldwide. Significant advancements have been observed in the thera-py for non-small celllung cancer (NSCLC). With constant extension of new awareness regarding the histopathology of lung cancer, ho-mologous chemotherapeutic regimens have been developed on the basis of histopathological sub-typing methods. With developments in molecular biology, driving gene mutations during tumorigenesis and progression have been discovered. A series of targeted drugs for various molecular subtypes has also been investigated and developed on the basis of these mutations. This review summarizes recently published clinical outcomes on the management of advanced NSCLC and strategies to apply drugs in clinical treatments.

The mechanism of coronary artery thrombosis(CAT)caused by Kawasaki disease is not clear yet.Endothelial injury,hypercoagulability and hemodynamic change of coronary arteries are now considered as the main causes in recent studies.As The clinical symptom of acute thrombus caused by Kawasaki disease is un-conspicuous,cardiac ultrasound should be use actively and thrombolytic therapy should be performed within 12 hours after thrombus formation or the onset of acute myocardial infarction.Intervention or intravenous thrombol-ysis are both proved to be effective.Treatment with oral antitplatelet drugs,such as aspirin,combine with warfa-rin is suggested to relieve acute myocardial infarction in the chronic phase.The adverse reactions of antithrom-botic and anticoagulant drugs should be monitored though they are minor.

Objective: The FDA regulation requirements for medical device software are relatively mature and systematic, and the research on the FDA regulation thinking of medical device software helps to promote the regulation work of the medical device software in our country. Methods:Based on the comparison of the 1998 edition and 2005 edition FDA software submission guidance, the trend of the FDA regulation requirements for medical device software was analyzed, and then its regulation thinking was discussed according to other current effective software-related guidance. Results:FDA integrally improves the submission requirements for all medical device software, especially for the minor Level of Concern software, and simplifies the requirements for design specification, verification and validation, but strengthens the requirements for traceability analysis and revision history. Conclusion: The regulation work of the medical device software in our country needs to fully consider the particularity of the medical device software, strengthen the audit of software quality management system, implement the software traceability analysis, and determine the regulation requirements for software change.
