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.

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 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 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.

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.

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.

Tachycardia induced cardiomyopathy is a kind of cardiomyopathy caused by sustained or recurrent tachycardia.Various types of tachyarrhythmias can cause TIC, and the main clinical manifestations of it are cardiac dilatation and cardiac dysfunction.TIC can occur at all ages and is a reversible and acquired cardiomyopathy with a generally benign prognosis.After early diagnosis and reasonable treatment to relive the tachycardia, the function of the heart can partially or completely recover.In clinical practice, pediatricians do not fully understand the disease, as a result, it is easily missed, misdiagnosed, then the proper diagnosis and treatment will be delayed.This article provides a systematic overview of the pathogenesis, clinical characteristics, diagnosis, differential diagnosis, treatment and prognosis of TIC in children, and aims to provide a basis for clinical pediatricians to recognize it early and treat it promptly.

Kawasaki disease shock syndrome (KDSS)is a critical state of Kawasaki disease(KD)characterized by peripheral circulatory perfusion disorder and hypotension.The main causes of shock include cytokine imbalance, myocardial dysfunction and vasculitis with continuous capillary leakage.Compared with KD, KDSS shows longer fever duration, more severe inflammatory reaction, more obvious increase of D-dimer level, higher incidence of cardiovascular system abnormalities and multiple organ dysfunction, and higher proportion of unresponsive IVIG and glucocorticoid use.The early clinical manifestations and laboratory examination results of KDSS are not typical, so it is difficult to make an earlier diagnosis.The therapy of KDSS mainly includes anti-shock therapy and anti-inflammatory therapy may be associated with faster remission of shock and inflammation and better improvement of long-term prognosis.Many factors are related to the occurrence and development of KDSS.

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.
