The construction of art mass organization in medical colleges can consummate quality education system,make up insufficiency of the classroom teaching,promote medical students' comprehensive development and innovative ability and mold fine mind and lofty medical ethics.Therefore,it has important theoretical and practical significance to study existing problems and find out the ways to improve art mass organization construction of medical schools.

The principles of step by step, the combination of practice and theory, the co-existing of being implicit and explicit, the equality between guidance and autonomous can be followed to construct humanities curriculum system in content, resources, teaching staff and teaching in medical colleges for nationalities. Furthermore, humanities curriculum system must insist on a fundamental concepts that the human theory is the essence of medicine, and the humanities is the basic structure of medicine and the key to success is the training of humanities teachers.

INTRODUCTION: Respiratory virus (RV) infections have been implicated in acute exacerbation cardiopulmunary conditions. This study aimed to determine the prevalence of RV infections in patients admitted to the cardiology unit with acute decompensated heart failure (ADHF) in a tertiary hospitals in Singapore. MATERIALS AND METHODS: This was a single-centre, prospective observational study. A total of 194 adults (aged >21) admitted to the Singapore General Hospital with ADHF were recruited. A nasopharyngeal swab was taken for multiplex polymerase chain reaction (PCR) detection of influenza virus, rhinovirus, parainfluenza virus (HPIV), human coronavirus (HcoV), adenoviurs, human bocavirus (HboV), human metapneumovirus (hMPV), and respiratory syncytial virus (RSV). RESULTS: Twenty-five (13%) had RVs detected by RV multiplex PCR. There comprised 9 rhinoviruses (36%), 4 influenza A viruses (16%), 3 HPIV (12%), 3 HCoV (12%), 2 adenoviruses (8%), 1 human HBoV (4%), 1 hMPV (4%), and 1 RSV (4%). Symptoms-wise, cough was significantly more common in the PCR-positive group (48% vs 24%, = 0.02). There were no statistically significant differences in laboratory investigations (haemoglobin, leukocytes, platelets, creatine kinase, creatine kinase-muscle/brain, troponin T), and radiology findings between RV PCR-positive and -negative groups. The PCR-positive group did not have increased mortality or length of hospital stay. CONCLUSION This study identified a considerable burden of RVs in our ADHF cohort, and highlights the need for prevention of RVs in this group of patients. We also recognised the difficulty with clinical diagnosis of RVs in ADHF patients.

Posttransplant lymphoproliferative disease (PTLD) is a fatal complication after lung transplantation, which is intimately associated with age, immunosuppression level and Epstein-Barr virus (EBV) infection, etc. Reducing immunosuppression level, rituximab therapy and T cell immunotherapy are common treatments for PTLD. With the rapid development of lung transplantation in China, PTLD after lung transplantation has attracted widespread attention. This article reviews the risk factors, pathological types, clinical manifestations, diagnosis, treatment, prognosis and prevention of PTLD after lung transplantation, aiming to provide reference for early monitoring and management of the incidence and progression of PTLD.

PURPOSE: Toll-like receptor 3 (TLR3) recognizes to viral double-stranded RNA and is involved in antiviral defenses. A probable role of TLR3 gene variants in the pathogenesis of aspirin-intolerant asthma (AIA) has been suggested. AIA patients present more frequent asthma exacerbations in which respiratory viral infections could be an exacerbating factor. IgG subclass deficiency was commonly present with bronchial asthma. Based on previous findings, we investigated whether TLR3 variants could affect IgG3 subclass deficiency in AIA. METHODS: We enrolled 279 AIA patients, 403 aspirin-tolerant asthma (ATA) patients, and 315 normal healthy controls (NC) in this study. TLR3 polymorphism at the promoter region -299698G>T was genotyped. The serum levels of IgG subclasses were determined by the single radial immunodiffusion method. Expressions of IgG3 and TLR3 on Epstein-Barr virus transformed-B cells isolated from asthmatic patients were evaluated by flow cytometry to investigate B-cell functions. RESULTS: The TLR3 -299698 T allele was significantly associated with severity and IgG3 deficiency in the AIA group (P=0.044 and P=0.010, respectively), but not in the ATA group. IgG3 expression on B cells from asthmatics with IgG3 deficiency was significantly lower compared to those without (P=0.025). There was a positive correlation between IgG3 expression levels on B cells and serum IgG3 levels (r 2=0.434, P=0.002). CONCLUSION: These results suggest that the TLR3 -299698G>T polymorphism may be associated with IgG3 subclass deficiency and severity in AIA.

Purpose: Cranial magnetic resonance imaging (MRI) is recommended to identify intracranial lesions in girls with central precocious puberty (CPP). Yet, the use of routine MRI scans in girls with CPP is still debatable, as pathological findings in girls 6 years of age or older with CPP are limited. Therefore, we aimed to identify the prevalence of brain lessons in CPP patients stratified by age group (0–2, 2–6, and 6–8 years). Methods: This retrospective cross-sectional study recruited 257 girls diagnosed with CPP for 6 years (2010–2016). MRI was used to detect brain abnormalities. Levels of luteinizing hormone, follicle-stimulating hormone, and sex hormones in blood samples were measured. Results: Most girls had no brain lesions (82.9%, n=213), and of the minor proportion of girls with CPP that exhibited brain lesions (17.1%, n=44), 32 girls had organic CPP. Pathological findings were detected in 33.3% (2 of 6) of girls aged 0–2 years, 15.6% (5 of 32) of girls aged 2–6 years, and 3.6% (8 of 219) of girls aged 6–8 years. Hypothalamic hamartoma and tumors in the pituitary stalk were the most common pathological findings. The likelihood of brain lesions decreased with age. Girls with organic CPP were more likely to be younger (6.1±2.4 vs. 7.3±1.3 years, p<0.01) than girls with idiopathic CPP. Conclusion Older girls appeared to have a lower prevalence of organic CPP. Clinicians should cautiously use cranial MRI for girls aged 6–8 years with CPP.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.
