Objective To investigate the epidemiology and clinical features of epidemic cerebrospinal meningitis of children in Shanghai area in the last 2.5 years. Methods A retrospective study was conducted in 27 hospitalized patients with epidemic cerebrospinal meningitis by analyzing the clinical manifestation,epidemiology and laboratory test fingdings from Jan.2006 to Jun.2008.Statistical analysis of the clinical manifestations of cases in serogroup A,B and C was performed according to Neisseria meningitidis infection. Results There were sporadic cases of children with epidemic cerebrospinal meningitis in Shanghai area in the last 2.5 years.The seasonal distribution illustrated the peak occurrence from Feb.to Apr.Among all these cases,92.6% were floating children.Common types(74.1%) were the predominant clinical manifestations and the others were fulminate types(25.9%).Four cases in each of serogroup A and B,and 8 cases of serogroup C were identified by serotyping on 14 Neisseria meningitidis strains and genotyping on the other 2 cases′ cerebrospinal fluid specimens.All the patients in serogroup A with meningococcal diseases were not vaccinated before and 25.0% of them belonged to fulminate types.Half of the cases had petechia on the skin and the prevalence of skin necrosis was 25.0% and 50% had complications of nervous system.No fulminate type was present in cases of serogroup B meningococcal disease and only 1 case had slight petechia on the skin.However,intensive convulsions occurred in 75.0% of the patients,and all of them had complication of nervous system,with a few had sequela.Among the patients in serogroup C meningococcal disease,62.5% patients were vaccinated with serogroup A Neisseria meningitidis.In serogroup C,Neisseria meningitidis infection was found in each age group,with petechia on skin,skin necrosis,immunity correlation fever and complications of nervous system in 87.5%,50.0%,75.0% and 12.5% of the patients,respectively. Conclusions 1.Epidemic cerebrospinal meningitis occurred sporadically in children in Shanghai area,the majority of patients were floating populations.2.Clinical manifestation was typical in patients of serogroup A meningococcal disease.Subdural effusion or ventricalitis was more common in patients of serogroup B meningococcal disease.In serogroup C,Neisseria meningitidis was the most prevalent serotype leading to epidemic cerebrospinal meningitis.More cases were found in patients infected with serogroup C,Neisseria meningitidis with severe shock and immunity correlation fever compared with the other groups.Prophylactic vaccination of serogroup C polyvalent meningococcal organism should be recommended.

Objective To explore the changes of asphyxial neonatal gastric juice pH values,and to provide data for making early intervention measures.Methods Eighty asphyxial neonates were divided into routine group(55 cases)and intervention group(25 cases).Twenty neonates who weren't asphyxial were set as a control group.Those neonates' gastric juice pH values were monitored dynamically.The newborns in intervention group were treated by giving smecta and cimetidine intravenously on the routine treatment.The impairment occurrence conditions of these newborns' gastrointestinal functions were observed.Results The gastric juice pH values of asphyxial neonates were obviously lower than those of the control group at their birth(Pa0.05).The occurrence rate of gastrointestinal functions impairment was lowered(?2=16.0 P

Objective To investigate the treatment efficacy of lumbar spondylolisthesis patients with modic change. Methods The da-ta of 45 lumbar spondylolisthesis patients with modic change were analyzed retrospectively,which were admitted into hospital from January 2010 to December 2013 and received posterior lumbar interbody fusion ( PLIF) surgery. Those patients were tested by X-ray and Magnetic resonance imaging ( MRI) and confirmed the type of spondylolisthesis and Modic change. Based on the degree of spondylolysis and whether combined or not with Modic change,all the patients were divided into six groups:group A with Ⅱ grade spondylolisthesis;group B with Ⅲgrade spondylolisthesis;group C with Ⅱ grade spondylolisthesis with Modic typeⅠ;group D withⅡgrade spondylolisthesis with Modic typeⅡ;group E with Ⅲ grade spondylolisthesis with Modic type Ⅰ;group F with Ⅲ grade spondylolisthesis with Modic type Ⅱ. Those patients were evaluated preoperatively and postoperatively the scores according to the Visual Analogue Scale ( VAS) and Oswestry Disability Index ( ODI) systems,the obtained data were statistically analyzed and then were used to evaluated the treatment efficacy. Results The treatment efficacy of those patients were evaluated by follow-up work based on the scores of VAS and ODI systems,the results indicated that all those patients were improved in the scores of pain and ODI at different agrees. Within groups,the scores of low back and leg pain in VAS system and ODI preoperative were all significantly lower than that of postoperative (P<0. 0001). However,there were no significant differences of those scores among groups (P>0. 05). Conclusion Those spondylolisthesis patients with Modic change could obtained satisfactory clinical efficacy after posterior lumbar interbody fusion ( PLIF) surgery.

Objective In the heart,autophagy is important for the turnover of organelles at low basal levels under normal conditions,but is upregulated in response to stresses such as ischemia/reperfusion and in cardiovascular diseases such as heart failure. It can prevent the heart from injury under stress conditions. This study was designed to test the hypothesis that autophagy would be upregulated in the myocardium of children with cyanotic congenital cardiac defects. Methods Eighteen children with cyanotic (n=10) or acyanotic cardiac defects (n=8) who were admitted in our hospital from October 2008 to April 2009 and received surgical treatment were investigated. Samples from the right ventricular myocardium taken immediately after aortic clamping were morphologically studied with transmission electron microscopy for the ultrastructure. Microtubule-associated protein 1 light chain 3 (LC-3) was detected by Western blot analysis in the obtained samples. Results Children with cyanotic cardiac defects had higher oxyhemoglobin saturation before operation than those with acyanotic cardiac defects. Electron microscopy showed that the former group had more mitochondria,disordered arrangement,swollen endoplasmic reticulum and typical autophagosomes in the myocardial cytosol. LC3-II were significantly elevated in patients with cyanotic compared with those with acyanotic congenital cardiac defects (P

Objective To investigate the methylation status of 14-3-3σ promoter in nasopharyngeal carcinoma cell lines and the influence of de-methylation treatment on 14-3-3σ expression. Methods Methylation status of 14-3-3σ gene promoter and 14-3-3σ mRNA expression were detected by methylation specific PCR (MSP) and RT-PCR in nasopharyngeal carcinoma cell lines CNE1, CNE2,5-8F,6-10B and immortalized nonneoplastic human nasopharyngeal epithelial cell line, NP69. Four nasopharyngeal carcinoma cell lines were treated with 5-asa-2' -deoxycytidine(5-aza-2dC) in different concentration for 72 h, then 14-3-3σ promoter meth-ylation status and m RNA expression were assessed, and western-blot was performed to detect the expression of 14-3-3σ protein. Results 14-3-3σ promoter methylation was detected by MSP in all of the four nasopharyn-geal carcinoma cell lines untreated by 5-aza-2dC whereas not in the treated ones or the immortalized human na-sopharyngeal epithelial cell line, NP69. Accordingly, 14-3-3σ mRNA expression was significantly discounted in untreated nasopharyngeal carcinoma cell lines as compared with NP69. 5-aza-2dC treatment dose-depend-ently reversed 14-3-3σ promoter methylation status and consequently upregulated the expression of 14-3-3σmRNA and protein in 4 nasopharyngeal carcinoma cell lines. High-differentiated CNE1 was more sensitive to 5-aza-2dC than lowly-differentiated CNE2, 5-8F and 6-10B. Conclusion Promoter methylation directly leads to decreased 14-3-3σ gene expression in nasopharyngeal carcinoma cell lines, and 14-3-3σ promoter de-methylation perhaps indicates a new target for nasopharyngeal carcinoma treatment.

With the deepening of modernization of traditional Chinese medicine (TCM), the method of quantification and standardization of TCM (i.e., quantitative characterization of TCM) has been more and more widely accepted by researchers. Chemometrics processes complicated data of TCM through applied mathematics, statistics and com-puter technology. And multivariable study was introduced into the quantitative characterization of TCM with great achievements. This article reviewed existed problems of quantitative characterization in TCM, the principles, char-acteristics, limitations, commonly used statistical methods and application conditions on quantitative characteriza-tion of TCM. With this review, a reference for further study of quantitative characterization of TCM was provided and a further research idea of combination with main methods of chemometrics was given.
