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.

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 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

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.

A case of the 12-year-old female patient with first relapsed acute lymphoblastic leukemia was reported. During the induction chemotherapy, the patient, transfused with whole blood and granulocytes, developed diarrhea and generalized macular rash. The skin biopsy showed some changes compatible with graft versushost disease (GVHD). Therefore, the related literature was reviewed, and the clinical features of transfusionassociated GVHD and the measures for its prevention and treatment were succinctly introduced.

The importance of software version in the medical device software supervision does not cause enough attention at present. First of all, the effect of software version in the medical device software supervision is discussed, and then the necessity of software version in the medical device software supervision is analyzed based on the discussion of the misunderstanding of software version. Finally the concrete suggestions on software version naming rules, software version supervision for the software in medical devices, and software version supervision scheme are proposed.

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.

OBJECTIVE:To promote safe,effective,economical and proper medication.METHODS:Prescriptions in the outpatient and emergency departments of our hospital in2003were randomly selected;the irrational prescriptions were ana?lyzed with regard to drug descriptions,pharmacological knowledge and literatures.RESULTS:The irrational one amounted to4.92%of the total selected prescriptions;antibiotics drug abuses amounted to84.12%of the irrational ones.The irrational drug use problems were mainly seen in administration scheme,repeated dosage,menstruum,administration,drug combina?tion,compatibility and combined toxicity.CONCLUSIONS:Clinical pharmacist plays an important role in promoting rational drug use by checking prescriptions.

Magnetic resonance imaging has developed from a single observation of organisms’ anatomy and the change of morphology under the physiological and pathological conditions to the study of biology function and activity mechanism. Furthermore, it has entered into the molecular imaging and functional magnetic resonance imaging (fMRI), and diffusion-weighed imaging (DWI) is one of them, which is mainly used in the early diagnosis of cerebral infraction. This article elaborates diffusion-weighed imaging,the identification of acute and non-acute cerebral infarction by DWI in physiological basis of pathogenesis and the time vale of DWI examination. The author holds the opinion that it is of great significance to distinguish between acute and non-acute cerebral infarction by using DWI and that clinicians may adopt targeted therapies according to the different periods of cerebral infarction in order to avoid unsafe and unnecessarily risky treatments.
