Objective To retrospectively investigate the clinical features and incidence trends of hypertriglyceridemic acute pancreatitis (HLAP) in Guangzhou First People's Hospital for 20 years.Methods The medical records of 1 362 patients,who were admitted to Guangzhou First People's Hospital with acute pancreatitis during January 1991 to December 2010,were reviewed and 99 patients met the HLAP criterion.These patients were divided into four groups according to years (1991 ～ 1995,1996 ～2000,2001 ～2005,and 2006 ～2010).The incidence and clinical features were compared among the 4 groups.Results Among the 99 patients,there were 61 males and 38 females,the mean age was (44 ± 12) years old,and young male was predominant in HLAP.HLAP accounted for 7.3％ of all AP patients,and the incidence was increased 1.5 times during the 20 years period (5.4％,5.7％,6.7％,and 8.3％ respectively).The serum amylase level was (513.3 ±462.7) mmol/L,TG level was (12.7 ± 7.0) mmol/L,Ranson score was (1.2 ± 1.1),CTSI score was 2.2 ± 1.1,incidence of SIRS was 36.4％,and the incidence of MODS was 18.2％,and the incidence of pancreatic pseudocyst was 5.1％,but the incidence and mortality of SAP was not changed with time.The incidence and mortality of SAP of HLAP were significantly higher than those of acute biliary pancreatitis (20.2％ vs 8.5％,6.1％ vs 2.8％).The rate of blood purification increased from 0 to 10.7％,and the hospital stay was decreased from 26 d to 14 d,and the difference between the two groups was statistically significant (P ＜ 0.05).Conclusions Incidence of HLAP is increased gradually,with a trend towards more severe disease,but the prognosis is improved.

Objective To observe the changes of the intercellular spaces of squamous epithelium of lower esophagus in gastroesophageal reflux disease(GERD).Methods Eleven outpatients with GERD symptoms more than 3 months [6 with nonerosive reflex disease(NERD)and 5 with erosive esophagitis(EE)]and 5 healthy volunteers were recruited.All of them underwent endoscopy and 24-hr ambulatory pH monitoring.Biopsies were taken in lower esophagus(2 cm above Z-line)for electron microscope examination.Results Intercellular spaces of esophageal epithelial cell in volun teers,NERD patients and EE patients were (0.374?0.073)?m,(1.308?0.079)?m and (1.332?0.144)?m respectively,with significant differences between the control group and the NERD or EE group.There was no difference between NERD group and EE group.Conclusions Dilated intercellular spaces were seen in both NERD and EE cases,which was significantly different from the control cases.

To establish a new method for identifying genus of Lilium by DNA barcoding technology, ITS, ITS2, psbA-trnH, matK and rbcL sequences were analyzed in term of variation of inter- and intra-species, barcoding gap, neighbor-joining tree to distinguish genus of Lilium based on 978 sequences from experimental and GenBank database, and identification efficiency was evaluated by Nearest distance and BLAST1 methods. The results showed that DNA barcoding could identify different species in genus of Lilium. ITS sequence performed higher identification efficiency, and had significant difference between intra- and inter-species. And NJ tree could also divide species into different clades. Results indicate that DNA barcoding can identify genus of Lilium accurately. ITS sequence can be the optimal barcode to identify species of Lilium.

Objective To evaluate the effects of infliximab (TNF-α monoclonal antibody ) on intestinal barrier injury in ANP complicated with MODS in a rat model.MethodsThirty SD rats were randomly divided into sham operation group (SO),ANP group and infliximab treatment group.Sodium taurocholate (4.5％) was injected into the pancreatic duct to induce ANP complicated with MODS model.Infliximab (8 mg/kg) was injected via tail vein in 6h after modeling in infliximab group.Same amount of 0.9％ NS was injected into the pancreatic duct in SO group.After 24 h of modeling,all rats were sacrificed,intestine and pancreas samples were collected for pathologic examination.The blood samples were harvested.The serum levels of amylase,TNF-α,diamine oxidase( DAO),D-lactate,and the rate of carbon propelling in ileum were measured.ResultsThe serum levels of amylase were ( 1125 ± 331 ),( 11024 ± 2203 ),( 545 ±30) U/L in SO group,ANP group and infliximab group; the serum levels of TNF-α were (12.1 ± 4.0),(107.6 ± 18.5),(75.8 ±5.9) U/L; the pathological scores of pancreas were 2.25 ±0.38,14.10 ±0.22,3.93 ± 0.67,the difference among the 3 groups was statistically significant ( P ＜ 0.05 ).The pathological scores of intestine were 2.29 ± 0.32,6.61 ± 0.58,3.91 ± 0.41 ; the DAO levels were ( 87.88 ± 34.51 ),(146.30 ±12.99),(115.00 ± 18.58) ng/ml; the D-lactate levels were (1.50 ±0.49),(2.32 ± 0.35),(2.02 ± 0.25 )mmol/L; and the rates of carbon propelling in ileum were (0.64 ± 0.04 )％,(0.28 ±0.08)％,(0.52 ±0.09)％,the difference among the 3 groups was statistically significant (P ＜0.05).ConclusionsInfliximab can effectively prevent dysfunction of intestinal barrier and improve motility in ANP rats.

This study provides the candidate sequences in the identification of Radix et Rhizoma Clematidis and its adulterants using DNA barcoding. We amplified and sequenced the region psbA-trnH, with the data of 284 sequences from GenBank, the differential intra- and inter-specific divergences, genetic distance, barcoding gap were used to evaluate five barcodes, and the identification efficiency was assessed using BLAST1 and Nearest Distance methods. The results showed that psbA-trnH barcodes performed high identification efficiency and inter-specific divergences among the five different DNA barcodes. Analysis of the barcoding gap and NJ tree showed psbA-trnH was superior to other barcodes. Based on the identification and PCR amplification efficiency, psbA-trnH can be the ideal barcode to identify Radix et Rhizoma Clematidis and its adulterants accurately.

Objective To explore the expression of c-Fos protein and character of mossy fiber sprouting(MFS) in hippocampus of rat with febrile seizures(FS).Methods Thirty-six 21-day-old male Sprague-Dawley rats were randomly divided into FS group,febrile control(FG) group and normal control(NG) group.FS was established by hyperthermal bath.Immune histochemistry and(Timm′s) staining were used to examine the expression of c-Fos protein in CA1 region and MFS in CA3 region of hippocampus.Results Excessive expression of c-Fos protein presented in the hippocampal CA1 region of FS group.The surface area percentage of c-Fos protein of FS group[(2.26?0.23)%] was higher than that of FG group[(1.08?0.19)%] and NG group[(0.71?0.14)%],there were significant difference between FS group and the other two groups(?~2=10.48 P

Objective To explore the personality characteristics of abused children in order to reduce the incidence of child abuse.Methods Two hundred and ninty five middle school students were investigated with general questionnaire and Eysenck Personality Questionnaire of children. Eighty six students experiencing child abuse (CA) last year as study group and one hundred and ninety six non-abuse children as controls (NCA) were analyzed by means of Eysenck Personality Questionnaire of children.Results The score of neuroticism in CA group was significantly higher than that in the control group (55.62±10.60/52.65±10.98,t=-2.114 P=0.035). The score of lie in CA group was significantly lower than that in control group (42.21±9.87/46.04±9.20,t=3.184 P=0.002). On the impact of different sex, the psychoticism score of male was significantly higher than that in the control group(52.37±11.49/48.04±9.97,t=-2.227 P=0.028), and the lie score was significantly lower than that in control group(41.03±9.18/46.18±8.79,t=3.125 P=0.002).The scores of those in the female were not significant.Conclusions There is a close association between the unstable emotion and child abuse in children, so training emotional self-control and emotional expression of children might be a intervention strategy in the future. In addition, the frequency of lie in children is probably one of factors that determine whether children are abused or not.

Aim To monitor the whole blood trough concentration of cyclosporine A (CsA) in renaltransplant recipients reciving triple therapy with mycophenolate mofetil, cyclosporine andprednisone and to establish an optimal therapeutic window of CsA. Methods Sampleswere measured by specific fluorescence polarization immunoassay. According to the timeafter operation and different therapy plan, the whole blood trough concentration of CsA ineach group was compared with that in control group.Results The optimal therapeuticwindow of CsA with MMF plan was 150~300 ?g? L-1 (less than one month after op-eration), 120~260?g?L-1 (1~
