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.

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

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.

Methods :Morning venous blood was taken from the 5604 subjects undergoing health examination to measure blood glucose lev‐el ,and their body weight and height were measured at the same time ,then body mass index (BMI) was calculated and analyzed .Results:Among the 5604 subjects , prevalence rates of overweight and obesity were 42.1% and 13. 3% respectively ,and they were 50% and 16. 4% in men ,and 25. 4% and 6. 8% in women respectively .Among different age groups (except ≥71 years group) , prevalence rate of overweight in men was significantly higher than that of women , P<0.01 all;except ≥61 years subjects , prevalence rate of obesity in men was significantly higher than that of women ,P<0.01 .In overweight group ,risk relative (RR) of impaired fasting blood glucose and dia‐betes mellitus to those of subjects with normal body weight was 2.32 (95% CI 1.91~2.82) and 2.92 (95% CI 2.31~3.70) respectively ;in obesity group , RR of impaired fasting blood glucose and diabetes mellitus to those of subjects with normal body weight was 3.2 (95% CI 2.57~3.99) and 5.17 (95% CI 4.53~5.90) respectively , P=0.001 all . Conclusion:Overweight and obesity have become a common problem among our customer groups .Compared with those with normal body weight ,overweight and obesity greatly increase risk ratio of impaired fasting blood glucose .

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.

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.

Due to the advance of CT equipment, combined with the current intensifying doctor-patient conflict, the indication of CT examination is relaxed, even expanded to the examination of benign lesions, which contributes to the blind diagnosis using CT or the so-called“Casting a big net”. However, X-rays bring two kinds of risks. One of them is the risk of the accumulated X-rays, the other one is the missed diagnosis resulting from the poor image quality, which is caused by the low amount of radiation. Therefore, how to strike a balance between these two not only becomes the focus of academic circles, but sparks the whole society’s attention. This article elaborates X-rays hazards, CT radiation does, application of Multiple Detector Spiral CT, purpose and principles of radiological protection and optimization of CT scanning technology. The author believes “exposure does individualization” can be achieved under the principle of ALARA (as low as reasonably achievable), or we can even minimize the exposure does according to the requirements of diagnosis and accept the image with appropriate noise.

Objective To compare the effects of the two kinds of crystalloid solutions on glycometabolism in type 2 diabetic patients during the operation for the sclestion of the most suitable crystalloid solution. Methods In the forty scheduled gastrointestinal operation patients,there were twenty (D-group) type 2 diabetic patients and the others (N-group) were non-diabetic patients. Each of the two groups were randomly divided into two groups according to infusing different crystalloid solutions: lactated Ringer’s solution (L group), Plasma Lyte A (A group).So the patients were divided into D-L group,D-A group,N-Lgroup,N-A group.The blood glucose concentration,the blood lactate concentration and artery blood gas analysis before operation (T0) and at the end of operation(T1)were measured . Results The blood glucose concentrations had significant increase at the end of operations,and the blood glucose concentrations of D group were higher than that of N group at T0 and T1.The lactate concentrations before operation were normal in all the patients, but the lactate concentrations were over the normal limits after infusing lactated Ringer’s solution and remained normal after infusing Plasma Lyte A.The lactate concentrations had significant increase in the other three groups except N-A group. Conclusion Plasma Lyte A is the more safe and efficient crystalloid solution for diabetic patients during the operation.
