Enterovirus 71 (EV71) is one of the major pathogens that cause hand foot and mouth disease.Epidemics and pandemics have been periodically reported worldwide.EV71 also can cause serous complications and lead death in children.The mechanisms of EV71 cause serious complications has remained unclear,may relate to many factors,including cell tropism,cell death and host immune responses.This article reviews the recent advances in the identification of factors determining EV71 cell tropism,the associated mechanisms of viral infection-induced cell death and the interplay between EV71 and immunity.

Objective To study the high-frequency ultrasound features of papillary thyroid microcarcinoma and pathological features.Methods The ultrasonic diagnostic features of 89 cases of papillary thyroid microcarcinoma were analyzed retrospectively,and the ultrasound results and pathological results were compared.Results In this study,high frequency ultrasound examination showed that the thyroid ultrasound diagnosis coincidence rate of papillary microcarcinoma was 94.4％.Patients mainly concentrated in 40 ～ 59 years,8 cases of type Ⅰ blood flow,16 cases of type Ⅱ blood flow,65 cases of Ⅲ blood flow,83 cases of L/T (aspect ratio).Conclusion The different pathological features of papillary thyroid microcarcinoma accompanied with the different ultrasound images.Doppler high frequency ultrasound in the identification and diagnosis of papillary thyroid microcarcinoma is accurate,convenient operation,and low cost,which is worthy of clinical application.

Stereotactic body radiation therapy (SBRT) has been increasingly used in the treatment of early-stage non-small-cell lung cancer (NSCLC).Different from conventional radiotherapy,SBRT is characterized by the delivery of high-dose radiation in 1 to 5 fractions with a high degree of precision and steep dose gradients that minimize the dose to normal tissues,and image guidance technology,image fusion technology and respiratory gating system make the therapy more accurate.SBRT delivers higher biological equralent dose (BED) than conventional radiotherapy.The latest small sample data have suggested outcomes for SBRT patients that superior to the success rate of surgery,and the evidence for SBRT over conventional radiotherapy has resulted in a major change in the standard of care for inoperable NSCLC patients.

Objective Inaccurate dosing is an important cause of medical malpractice, how to adjust the medication dose to overcome the excessive deviation will be discussed in this paper. Methods Gold zone method was proposed on the basis of the probability theory and mathematical statistics for handling inaccurate dosing problems. Investigation and study in large sample size was carried out on adverse reactions of Cefamandole Nafate for Injection by adopting the method. Results The conclusions from the super large sample size test indicate that there is highly significant difference of total adverse reaction rates between taking values within and outside golden zone of dosage, and the adverse reaction rate of taking values within golden zone is significantly lower than that of outside golden zone. It is noteworthy that when dosage was lower than golden zone,the adverse reaction rate was significantly increased,which is more than 4 times of that within golden zone. Conclusion It is effective measures and simply and easy to apply that taking values within golden zone of dosage reduce adverse drug reactions,probability within golden zone less than 1/4 range of experience that contains the actual demand of the body up to 70%.

The S100 proteins are a multi-gene calcium-binding family,which are differently expressed in a variety of tumors.It is found to be associated with tumor invasion and metastasis.As a tumor-associated biomarkers,unraveling the relationship between S100 and prostate cancer progression as well as molecular mechanisms,would provide an important basis for the clinical diagnosis and therapeutic monitoring.

Objective To investigate the relationship between the serum markers and genotype with viral load in chronic hepati-tis B in order to improve the level of clinical treatment.Methods 819 patients with chronic hepatitis B in our hospital from April 2010 to April 2013were selected as the study subjects and performed the genotyping.The hepatitis B virus(HBV)DNA level was detected by using real-time fluorescence PCR.Results Among the 819 cases of positive HBsAg,357 cases were positive HBV-DNA,accounting for 43.59%;HBeAg(+)accounted for 90.11%;in the positive modes of serum markers and viral load,most of positive cases were HBsAg,HBeAg,HBcAb and HBsAg,HBeAb,HBcAb,accounting for 88.52%;HBV genotyping had B,C,BC mixed types and unclassified type,the logrithm levels of viral DNA were(7.187 ±1.668),(7.184 ±1.558),(7.208 ±1.447)and (7.313±1.505),there was no statistically significant difference among them(P >0.05).Conclusion The virus gene in the patients with chronic hepatitis B is dominated by type C,in which serum markers HBeAg and HBV-DNA viral load have the lose correlated, the infected virus genotype has the low correlation with the viral load.

Objective:To Integrated PACS and hospital information systems (HIS), and improve the efficiency of PACS, and improve the user experience. Methods:Base on deeply analysis of existing problems in system application, using process optimization, software optimization, and hardware upgrades manner optimize PACS. Results: PACS and HIS realized Integrated, improving the overall performance of the PACS. Enhance the user experience and expand the application scope of PACS. Conclusion: Deeply analysis of existing problems should be done before optimizing the system. Process optimization, software environment optimization should be considered as the most important and upgrading and replacement of the hardware as the secondary.

The pattern/symptom differentiation system in acupuncture treatment is lack of the unique characteristics and advantages in theory and clinical practice and it just rigidly adopts the methods of pattern/symptom differentiation of the other disciplines in TCM. In fact, it is necessary to have the unique and more practical theoretic system to guide acupuncture treatment. According to the characteristics of acupuncture in diagnosis and treatment, the acupoints selection based on "disease-symptom-location" combination becomes the law of acupuncture treatment. The acupoints selection based on "disease-symptom-location" combination is the expression to concretize the diagnosis and treatment of disease under the guidance of pattern/syndrome differentiation. Both of them are originated from the general principles of TCM and for the particular disciplines of TCM. The acupoints selection based on "disease-symptom-location" combination benefits the promotion and application of acupuncture.

Our previous study showed that malignant phenotype of human promyelocytic leukemia cells could he suppressed by fusion of them with mouse reticulocytes. In order to investigate the morphological changes for malignancy reversion, the present experiment was designed to study the microscepic and submicroscopic structure of cybrid cells and compared with their parental tumor cells. The results indicated that during the short period of cybrid cell cultivation, nuclei of numerous cybrid cells became pyknotic and eccentric, and some cells showed the process of nuclear expulsion (denucleation). The cybrids which cultivated for long period in vitro developed into more mature cells along both myeloid and erythroid differentiation pathway. The effects of mouse reticulocyte cytoplasmic factor on differentiation pathway of human promyelocytic leukemia cells were discussed.

Video assisted thoracic surgery(VATS) was rapidly developed in recent years.It's been widely accepted because it was minimally invasive and the patients were fast recovery with a survival rate similar to routine thoracotomy patients.However,more and more attention was paid to the side effect of general anesthesia with double cavity intubation during the surgery.Nonintubated thoracoscopic surgery for lung cancer was progressively developed.This surgery method decreases the side effect compared to general anesthesia with double cavity intubation.However,more surgical difficulty,additional surgical risk and prolonged surgery time were all inevitable become disadvantages of this new method.The less side effect of general anesthesia for patients and the more challenge for thoracic surgeon was brought simultaneous by this new method.More clinic trial should be implemented in validating the advantages and disadvantages.
