Objective To know the epidemiological characteristics of hand-foot-mouth disease in Yangpu District and provide evidence for specific strategies and measures of hand-foot-mouth disease activity prevention and control. Methods Descriptive analysis of the data from hand-foot-mouth disease epidemic situation in Yangpu District from 2005 to 2008 was made. Results 1 348 cases were reported in the whole Yangpu District from 2005 to 2008, and no severe cases, no death. The average morbidity in Yangpu District was 27.48/100 000. The male to female ratio was 1.46∶1. The infection occurred to infants aged from 1 year to 5 years (85.39%). The incidence of the native population children aged 2 to 3 exceeded 10/100 000. The season peak appeared from May to July (70.18%), and outbreaks used to occur at nurseries and kindergartens. The typical clinical presentations mainly included fever and rash. The rash mainly occurred to hands, feet, mouth, buttocks and so on. Conclusions Incidence varied significantly between different sexes, seasons and ages. It can cause large-scale epidemic in a short period of time, the epidemic was very difficult to control, but the leaders attach importance to take the early warning and monitoring, accuratey deal with emergencies, health education promotion and training of comprehensive measures, the epidemic can be effectively controlled.

Grid management plays an important role in improving the efficiency of social service management. The authors explored the establishment of a nosocomial infection grid management model and implemented it at a tertiary general hospital in Shanghai. χ2 test results showed that since the hospital fully implemented the grid management model in early 2016, the number of hospital infections, surgical site infections, type I surgical incision infections, and ventilator-related pneumonia had shown a downward trend year by year. The number of inspections before the use of antibacterial drugs, the number of blood cultures submitted for fever patients, and the timing of hand hygiene compliance showed an increasing trend year by year( P<0.05), and the management of nosocomial infection was more effective than the previous period. The application of grid management model required establishment of grid organization structure, control of key links, implementation of the special personnel responsibility, formulation of a performance evaluation system, and implementation of incentive measures. The grid management model can significantly reduce the risk of hospital infection, improve the efficiency of hospital infection management, and was valuable to be applicated and promoted in medical institutions.

Objective To observe the damage effect of borneol on rabbit corneal epithelial cells. Methods After the treatment with borneol at 100, 200, 400 μg·mL-1 respectively, the viability of rabbit corneal epithelial cells was determined by methyl thiazolyl tetrazolium ( MTT) assay, cell apoptosis was determined by flow cytometry with Annexin V- fluorescein isothiocyanate/propidium iodide ( FITC/PI) staining, and Caspase-3 mRNA expression was detected with real-time reverse transcription polymerase chain reaction ( RT-PCR) . Results Borneol at the concentrations of 100, 200, 400 μg·mL-1 inhibited the activity of rabbit corneal epithelial cells. Compared with the normal control group, borneol increased the rate of apoptosis, and enhanced the Caspase-3 mRNA expression in rabbit corneal epithelial cells ( P<0.05 or P<0.01) . Conclusion Borneol can inhibit the proliferation of rabbit corneal epithelial cells, induce cell apoptosis through enhancing the expression of apoptosis-related gene Caspase-3 mRNA.

The postoperative complications were fewer,post-operative hospital stay was shorter,incision time was shorter(P=0. 000) and pain scores was lower(P=0. 000) in study group than that in control group. Basic hospital has the capacity to conduct this technical. Conclusion VATS is feasible to carry out in basic hospital.

Objective To investigate the effectiveness and safety of peritoneal dialysis(PD) in premature infants with acute renal failure(ARF).Methods In the neonatal intensive care unit (NICU) of Guangdong Province Maternal and Children Hospital, 12 premature infants underwent continuous PD due to ARF from March 2012 to March 2015, without using any antibiotics in the dialysis fluid.Before and after dialysis, the changes of serum urea nitrogen, creatinine, potassium and pH were compared.The complications (blockage, leakage, infection and necrotizing enterocolitis) and gastrointestinal nutrition situation were observed.Wilcoxon signed rank sum test was used for statistical analysis.Results Among the 12 premature infants, the underlying causes of ARF were sepsis (n=9), perinatal asphyxia (n=2), twin twin transfusion syndrome (n=l).The average gestational age was (30.9±3.2) weeks, the average body weight (before PD) was (1 461 ±525) g, the duration of PD was (3.8±2.6) d.Complications associated with PD included leakage (n=3) and peritonitis (n=2) in which Candids albicans and Klebsiella pneumonia were identified in ascites.Gastrointestinal nutrition was built up in six cases within one to four days after dialysis, among which one developing necrotizing enterocolitis on the 7th d after feeding.Finally, eight babies died (six died after initiative discontinued treatment and two died because of critically illness) and four patients were cured and discharged.Lower serum urea nitrogen and potassium levels and higher pH value were shown after dialysis than before [(9.16 ± 3.15) vs (12.71 ±6.98) mmol/L;(4.36±0.82) vs (6.24± 1.72) mmol/L;7.32±0.17 vs 7.21 ±0.17;Z=-2.118,-2.197 and-2.981, all P ＜ 0.05).Conclusion PD is an alternative safe and effective treatment for premature infants with ARF due to its simplicity both in manipulation and equipment requirement.

Background and objective Apolipoprotein E is a constituent of lipoproteins with considerable variation due to cysteine-arginine exchanges. We investigated the relationship between apo E gene polymorphism and the occurrence of coronary artery disease(CAD) in the older population of northern China. Methods The distribution of the HhaI polymorphisms of the apolipoprotein E gene was determined among 55 patients with CAD (CAD group), which was compared with that of 36 elderly subjects without CAD(control group). Results Genotype distributions at both sites (apo E gene 112-bp and 158-bp sites ) were different between the CAD and control groups. The CAD group had lower apolipoprotein Eε2frequencies than the control group (P＜0.05). Conclusion Individuals with apolipoprotein Eε2are likely to have a reduced risk of developing coronary artery disease as demonstrated by elderly subjects in Northern China.

Objective:To explore the suitable mouse strains,and establish stable human-miceX-GVHD model.Methods:This study selected the Nude Mice and NOD/SCID, and gave them sublethal dose of γ-ray irradiation whole body , and then intraperitoneal transplanted human peripheral blood mononuclear cells ( PBMC) to establish xenogeneic acute graft-versus-host disease model.By detection of human T cells in the mice′s tail venous blood,tissues,organs of the infiltration and other indicators (By flow cy-tometry and immunohistochemistry ) ,we compared the human immune cell infiltration rates in the two mouse model and recorded the survival time.Finally,we determined the appropriate strains of mice to establish X-GVHD.Optimization means were transfer ways and the appropriate amount of human PBMC ,and the best time to observe the changes of T cell phenotype and function.Results:The NOD/SCID mouse was more suitable for inducing human-mouseX-GVHD model,and there were no significant differences between intrap-eritoneal injection and intravenous injection.Transfer human PBMC more than 5 ×107 can establish human-mouseX-GVHD model.Using the optimized experimental conditions to establish the human-mouseX-GVHD model,we found the 7-11 days was the best time to observe the changes of T cell phenotype and function ,and the average survival time was(14.16±1.77)days.Conclusion:Human-miceX-GVHD model can be successfully established by intraperitoneal injection of 5×107 human PBMC into NOD/SCID, and the best time to observe the changes of T cell phenotype and function is between 7-11 days.

Objective:To investigate the clinical features of drug-induced hypersensitivity syndrome (DiHS) and enhance the recognition of its diagnosis and treatment.Methods:Drug-induced hypersensitivity syndrome diagnosed in the Second Xiangya Hospital of Central South University in recent 6 years were retrospectively analyzed and summarized.Results:Of 35 cases of drug-induced hypersensitivity syndrome there were ten types of suspected drugs. Antibiotics were the most common allergy-inducing drug, followed by allopurinol, antiepileptics, and non-steroidal anti-inflammatory drugs. The expected clinical findings of DiHS were characterized by skin rash, fever, enlarged lymph nodes, which may be accompanied by eosinophilia, liver function damaged. The lesions of DiHS were variable and the majority of cases 65.71%(23/35) were characterized by eruptive papules.The main therapeutic approach of DiHS was systemic application of glucocorticoids and intravenous immunoglobulin (IVIG). When necessary its combination with immunosuppressant or hemoperfusion (HP).Conclusions:DiHS should be on the high alert when a patient with medication history, rash, high fever and lymph nodes large, accompanied by eosinophilia, liver function damaged. Predictors of good prognosis are early diagnosis and treatment.
