This study aimed to analyze the etiology of the encephalitis outbreak in Longyan, Fujian Province, China in 2010, in order to provide valuable information for this prevention and control of this disease. Pathogens were confirmed from cerebrospinal fluid samples with fluorescent RT-PCR, virus isolation (RD cells), and neutralization tests. Then, the VP1 fragments or whole genome nucleotide sequences were determined for four virus strains using PCR. Homology was assessed using the MegAlign software, and a phylogenetic evolutionary tree was drawn using Mega 4.0 software. The results confirmed that the etiology of the outbreak was the ECHO6 intestinal virus, and the nucleotide sequence of the VP1 segment indicated that the C2 subtype was responsible. The genome sequence consisted of 7407 nucleotides, and resembled the genome of other ECHO and CoxB viruses with homology levels of 78.5%-87.3%. The encephalitis outbreak in Longyan in 2010 was caused by the ECHO6 C2 subtype intestinal virus, and its complete genome sequence length is similar to the standard strain (U16283) with a sequence homology of 80.4%.

UNLABELLEDOBJECTIVE To investigate the effect of Nepsilon-(carboxymethyl) lysine albumin (CMLs), a primary advanced glycation end products (AGEPs) isoform in diabetic body, on the function and angiogenesis of adipose tissue-derived stem cells (ADSCs) and the protective effect of Danhong Injection (DH). METHODS Human ADSCs were cultured and separated from human subcutaneous fatty tissue using enzymatic digestion and centrifugation. The morphology was observed using optical microscope and differentiation capacities assessed. Cells were exposed to 5 different interventions respectively for 24 h, i.e., PBS, 60 1 microg/mL BSA, 60 microg/mL CML-BSA, 100 microL/mL DH, and 60 micro./mL CML-BSA +100 microL/mL DH. Their effect on the proliferation, migration, apoptosis, and secretion were observed using WST-1 assay, Transwell assay, Annexin V-FITC/PI flow meter test reagent kit, human VEGF reagent kit, ELISA reagent kit, respectively. The effect on ADSCs angiogenesis was observed by in vitro angiogenesis test.

RESULTSCompared with the BSA group, the capacities of proliferation and migration could be significantly inhibited by CML-BSA, the apoptosis promoted, the secretion of VEGF reduced, and the angiogenesis of ADSCs weakened (P < 0.05). Compared with the blank control group, 100 microL/mL DH could significantly promote the proliferation and migration capacities of ADSCs, inhibit apoptosis of ADSCs, increase the secretion of VEGF, and improve the angiogenesis of ADSCs (P < 0.05). Compared with the CML-BSA group, the inhibition of CML-BSA on the proliferation and migration capacities of ADSCs could be significantly reversed, the promotion of CML-BSA on the apoptosis of ADSCs improved, the secretion of VEGF increased, and the angiogenesis of ADSCs elevated (P < 0.05).

CONCLUSIONclusion CMLs could significantly inhibit the proliferation and migration capacities of ADSCs, promote their apoptosis, and inhibit their angiogeneses, which could be improved by DH.

The main treatment strategies for chronic pancreatitis in young patients include therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) intervention and surgical intervention. Therapeutic ERCP intervention is performed much more extensively for its minimally invasive nature, but a part of patients are referred to surgery at last. Historical and follow-up data of 21 young patients with chronic pancreatitis undergoing duodenum-preserving total pancreatic head resection were analyzed to evaluate the outcomes of therapeutic ERCP intervention and surgical intervention in this study. The surgical complications of repeated therapeutic ERCP intervention and surgical intervention were 38% and 19% respectively. During the first therapeutic ERCP intervention to surgical intervention, 2 patients developed diabetes, 5 patients developed steatorrhea, and 5 patients developed pancreatic type B pain. During the follow-up of surgical intervention, 1 new case of diabetes occurred, 1 case of steatorrhea recovered, and 4 cases of pancreatic type B pain were completely relieved. In a part of young patients with chronic pancreatitis, surgical intervention was more effective than therapeutic ERCP intervention on delaying the progression of the disease and relieving the symptoms.

Objective To investigate the usage of distortion product otoacoustic emissions(DPOAE) in normal infants hearing screening.Methods One hundred infants(200 ears) without clinical condition of illness were checked in GSI 70 DPOAE screening.The pure tones were 2,3,4 kHz,the OAE screener scored the test result as a pass,when the responses were above the PASS/REFER line and the signal-to-noise was at least 10 dB.Results Ninty-four infants(188 ears) passed hearing screening. Four infants(8 ears) with ceruminous impaction didn′t pass screening;after extracting impacted cerumen from the external auditory meatus,the 4 infants(8 ears) passed screening.Two infants(2 ears) with secretory otitis media didn′t pass screening,but after medicine treatment for 1 week,they passed screening too.Conclusion DPOAE has advantages in infants hearing screening.J Appl Clin Pediatr,2006,21(3):168-169

Objective:To investigate the distribution and drug resistance of anaerobic bacteria in the patients with oral and maxillofacial infection.Methods:Aerobic and anaerobic bacteria cultures from 61 specimens of pus from the patients with oral and maxillofacial infection in the Department of Oral and Maxillofacial Surgery,Peking University School of Stomatology were identified.The culture type was evaluated by API 20A kit and drug resistance test was performed by Etest method.The clinical data and antibacterial agents for the treatment of the 61 cases were collected,and the final outcomes were recor-ded.Results:The bacteria cultures were isolated from all the specimens,with aerobic bacteria only in 6 cases (9 .8%),anaerobic bacteria only in 7 cases (1 1 .5%),and both aerobic and anaerobic bacteria in 48 cases (78.7%).There were 55 infected cases (90.2%)with anaerobic bacteria,and 81 anaero-bic bacteria stains were isolated.The highest bacteria isolation rate of Gram positive anaerobic bacteria could be found in Peptostreptococcus,Bifidobacterium and Pemphigus propionibacterium.No cefoxitin, amoxicillin/carat acid resistant strain was detected in the above three Gram positive anaerobic bacteria. The highest bacteria isolation rate of Gram negative anaerobic bacteria could be detected in Porphy-romonas and Prevotella.No metronidazole,cefoxitin,amoxicillin/carat acid resistant strain was found in the two Gram negative anaerobic bacteria.In the study,48 patients with oral and maxillofacial infection were treated according to the results of drug resistance testing,and the clinical cure rate was 81 .3%. Conclusion:Mixed aerobic and anaerobic bacteria cultures are very common in most oral and maxillofa-cial infection patients.Anaerobic bacteria culture and drug resistance testing play an important role in clinical treatment.

OBJECTIVETo discuss the reverse effect of Yinchenhao decoction(YCHD) in dimethyl nitrosamine (DMN)-induced hepatic fibrosis in rats.

METHODThe rat hepatic fibrosis model was established through the intraperitoneal injection with 1% dimethyl nitrosamine (DMN) with a dose of 1.0 mL x kg(-1) x d(-1) for consecutively three weeks, once for the first three days of each. The rats were randomly divided into six groups: the silymarin positive control group (50.0 mg x kg(-1) x d(-1), YCHD high (20.0 g x kg(-1) d(-1)), middle (8.0 g x kg(-1) x d(-1)) and low (3.2 g x kg(-1) x d(-1)) dose groups, the model group and the normal control group. The model group and the normal control group were orally administered with normal saline for consecutively five weeks. The pathologic changes in liver tissues were observed by HE staining. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), g-glutamyltransferase (g-GGT), hyaluronic acid (HA), laminin (LN), collagen type IV (CIV) and type III procollagen amino terminal peptide (PIIINP) in serum were determined. The metabolite profiling of amino acid and the content of hydroxyproline in liver tissues were also measured.

RESULTCompared with the model group, YCHD high and middle dose groups could significantly reverse the pathologic changes in liver tissues of rats. YCHD could reduce the levels of ALT, AST, gamma-GGT, HA, LN, CIV, PIIINP in serum and the content of hydroxyproline in liver tissues in a dose-dependent manner, and altered the metabolite profiling of amino acid in rat liver tissues.

CONCLUSIONYCHD has the effect in reversing dimethyl nitrosamine induced hepatic fibrosis in rats.

Objective To explore the effect of human leukocyte antigen B* genotype and age on serum homocysteine (Hcy) levels in children with seizures or epilepsy. Methods Fifteen children with seizures or epilepsy in whom HLA-B*15:02 genotype was detected during October 2015 to June 2016 were included. The plasma Hcy concentration in children with different genotypes was compared. The association of Hcy concentration and age was performed by linear-regression analysis. Results The mean concentration of Hcy was 8.38±4.23 μmol/L in children not carrying HLA-B*15:02 gene, which was obviously higher than that in children carrying HLA-B*15:02 gene 13.03±0.97 μmol/L (P<0.05). The Hcy concentration increased with the age (r2 =0.29, P<0.05). Conclusions Elder children with seizures or epilepsy carrying HLA-B*15:02 gene tend to have higher Hcy concentration and increased potential risk of disease. HLA-B*15:02 gene type and age can predict the changes of Hcy concentration in children with convulsions.
