Objective To contrast the curative effect of mosapride with that of domperidone on gastroparesis diabeticorum (DGP).Methods 52 DGP definite patients were divided into two groups randomly, mosapride group and domperidone group. The clinical effect and the change and untoward effect of gastric emptying time of this two medicines were observed after treatment for four weeks’.Results The curative effect of mosapride in treating DGP was obviously better than that of domperidone The total clinical effective rate between this two groups showed significant difference (P

Objective To investigate the prevalence of parenteral nutrition related central venous catheter infection in elder patients with malignant tumors,and explore the risk factors. Methods The clinical data of 366 patients with malignant tumors who were managed with parenteral nutrition after operation were retrospectively analysed.The data of age,gender, body weight,diagnosis of primary disease,surgical approach,past history,volume of blood and albumin transfusion and time of fever(body temperature ≥38℃) were collected.Parenteral nutrition related parameters such as time of parenteral nutrition,total calorie,non-protein cMorie,amount of fat,protein and glucose,calorie to nitrogen ratio and carbohydrate to fat ratio were also recorded. Results The mean age of 366 patients was (71.8±6.9)years,mean time of parenteralnutrition was (10.6±6.3)d,and total time of catheterization was 3 336 days.The prevalence of parenteral nutrition related central venous catheter infection was 2.5%(9/366).Logistic regression analysis demonstrated that the relative risks of plasma albumin level before parenteral nutrition and time of high fever to catheter infection were 1.257 and 2.518,respectively(P<0.01 for both). Conclusion Plasma albumin level before parenteral nutrition and time of fever were two risk factors for parenteral nutrition related catheter infection in elder patients with malignant tumors.

Objective To investigate the effect of bedside comprehensive ability training and critical thinking on the improvement of the personality maturity of pediatric nurses. Methods A total of 102 nurses with pediatric working years within one year were selected,and then they were arranged to receive critical thinking in combination with bedside comprehensive ability training for 6 months. After the training, pediatric nurses′ critical thinking ability, bedside comprehensive ability and personality maturity were evaluated. Results Before training, the total score of Critical Thinking Disposition Inventory-Chinese Version (CTDI-CV) , total score of bedside comprehensive ability, personality maturity score were 288.21±25.44, 75.24±2.51, 84.01±32.26, after training, they were respectively 324.18±25.93, 92.65±3.17, 125.57±35.47. Comparison of the scores before training and after training showed statistically significant difference(t=7.071, 30.750, 6.190,P < 0.05 or 0.01). Setting personality maturity as the dependent variable, and and CTDI-CV and bedside comprehensive ability as the independent variables, regression analysis showed that CTDI-CV and bedside comprehensive ability had a positive impact on the personality maturity. Conclusions The ability of pediatric nurses' critical thinking ability and bedside comprehensive ability training can promote the improvement of personality maturity of pediatric nurses.

Objective To summarize the method and effects of extracorporeal membrane oxygenation (EC-MO) for eight patients with sever heart or(and) lung diseases,and to get some reliable advises by analysis of retro-spoctive indications,timing and result in ECMO therapy. Methods Eight patients,aging from 26 to 82 and weighted from 57-87 kg were observed. Vein-artery ECMO was used in all patients,with the flow in 40-70 ml/(kg·min) and the activated clotting time(ACT) kept at 160-200 s. Results The time of ECMO support varied from 9.5 h to 84.1 h;Among the eight patients,one didn't weaned from ECMO and died,two who were weaned died 38 h ,6 h af-ter ECMO;five patients weanned succsesefully from ECMO and discharged. Conclusions ECMO do well in treat-ment of severe cardiopulmonary failure, resuscitation and support post cardiosurgery,and the indication and timing performance are important to the final result.

Objective　To evaluate the effects of lipid emulsion on parenteral nutrition associated liver dis ease (PNALD) in old tumor patients. Methods　A retrospective study was performed with 402 patients in Renji Hospital from January 2003 to December 2008. Patients were retrieved according to the following criteria: (1)age ≥60 years; (2) confirmed diagnosis of tumor, had no evidence of metastasis, and tumor was completely resected before receiving parenteral nutrition; (3) liver and kidney function was in normal range before receiving parenteral nutrition; (4) parenteral nutrition days ≥7; and (5) parenteral nutrition was infused in "all in one" bag via central venous. Patients with history of viral hepatitis or died in parenteral nutrition episode were excluded. These 402 patients aged (71.7 ±6.8) years and the average parenteral nutrition time was (10. 2 ±5.9) (range, 7-61 )days. In 311 patients (77.4％), non-protein calorie was obtained from carbohydrate and lipid and 91 patients (22. 6％ ) just obtained non-protein calorie from carbohydrate.　Results　The total prevalence of PNALD was 15.2％ (61/402). The prevalence of PNALD was 8.8％ (8/91) in patients receiving parenteral regiment without lipid and 17.0％ (53/311) in patients receiving parenteral nutrition with lipid, and there was no significant difference in prevalence of PNALD between two groups (χ2 = 3.72, P = 0.07 ). Lipid type and amount showed no significant effects on PNALD ( P ＞ 0.05 ). The fever days ( P ＜ 0. 001 ), baseline level of alanine transaminase (P ＜0. 001 ) and γ-glutamyltransferase (P ＜0. 001 ) were risk factors for liver injury by logistic regression. Conclusion　Lipid emulsion can be safely used in old tumor patients without affecting the occurrence of PNALD.

ObjectiveTo observe the influence of different dietary protein intake (DPI) on nitrogen balance and nutritional indices in peritoneal dialysis (PD) patients, and explore the minimal DPI to maintain nitrogen balance.MethodsThirty-four PD patients were randomly divided into group A, B and C with DPI as 1.2, 0.9 and 0.6 g·kg-1·d-1 respectively. All the patients admitted into our hospital and completed a 10-day assessment for nitrogen balance, as well as nutritional status including serum albumin (Alb), pre-albumin at baseline, the 7th and 10th day. ResultsThe DPI of group A, B and C was (1.18±0.05), (0.87±0.02), (0.66±0.03) g·kg-1·d-1, whose differences were significant (P<0.01). The dietary energy intake (DEI) was 129.29 (117.57-133.89), 111.71 (100.42-133.47), 146.86 (128.03-163.18) kJ·kg-1·d-1 respectively. Nitrogen balance was positive in group A, B, C [2.99 (2.15-4.72) g, 1.20(0.59-1.89) g, 0.24 (-0.87-1.27) g]. The BUN decreased at the 7th and 10th day (P<0.01) in group C. The BUN and phosphorus in group A increased, but without significant difference as compared to baseline. No significant differences of nutritional status were found among three groups throughout the trial. ConclusionMinimal DPI 0.65 g·kg-1·d-1 plus the supplement of protein loss in dialysate can maintain the nitrogen balance in peritoneal dialysis patients.

Objective To investigate the effect of anti-human immunoglobulin M (IgM) on proliferation,apoptosis,cell cycle and tumor formation in human nasopharyngeal carcinoma HNE-1 cell line in vitro and in vivo.Methods After treatment with anti-human IgM antibody,proliferation of HNE-1 cells was observed by cell proliferation inhibition assay,apoptosis and cell cycle of HNE-1 cells were detected by flow cytometry,and apoptotic cells were detected by TUNEL staining.Nude mouse models were constructed,and were injected intraperitoneally with anti-human IgM antibodies (once every 3 days).The growth of transplanted tumor was observed once every 4 days.After the fifth injection,the expression levels of IgM and gp96 protein in transplanted tumor were observed by immunohistochemical method (streptavidin-peroxidase conjugated method,SP).Results MTS assay showed that anti-human IgM antibody can significantly inhibit the proliferation of HNE-1 cells in concentration-and time-dependent manner (P＜0.05).Flow cytometry showed that the anti-human IgM antibody promoted a significant decrease in percentage of cells in G1 phase,a significant increase in percentage of cells in S phase,and a significant increase in apoptotic rate of HNE-1 cells (P＜0.05).TUNEL staining showed that the anti-human IgM antibody promoted apoptosis of HNE-1 cells (P＜0.01).Transplantation tumor experiment showed that anti-human IgM antibody can significantly inhibit the volume and weight of transplanted tumor (P＜0.05).The immunohistochemistry showed that the expression levels of IgM and gp96 proteins in mouse transplanted tumors after intraperitoneal injection with anti-human IgM antibodies were significantly lower than those of the control group (P＜0.05).Conclusion The anti-human IgM anti-body could effectively inhibit the proliferation of HNE-1 cells,promote apoptosis,and arrest cell cycle.Anti-human IgM antibody could also inhibit the growth of transplanted tumor in nude mouse,which might be related to inhibition of the expressions of IgM and gp96 proteins.

Periodontitis is an inflammatory disease that is characterized by progressive destruction of the periodontium and causes tooth loss in adults.Periodontitis is known to be associated with dysbiosis of the oral microflora,which is often linked to various diseases.However,the complexity of plaque microbial communities of periodontitis,antibiotic resistance,and enhanced virulence make this disease difficult to treat.In this study,using metagenomic shotgun sequencing,we inves-tigated the etiology,antibiotic resistance genes(ARGs),and virulence genes(VirGs)of periodontitis.We revealed a significant shift in the composition of oral microbiota as well as several functional pathways that were represented significantly more abundantly in periodontitis patients than in con-trols.In addition,we observed several positively selected ARGs and VirGs with the Ka/Ks ratio＞1 by analyzing our data and a previous periodontitis dataset,indicating that ARGs and VirGs in oral microbiota may be subjected to positive selection.Moreover,5 of 12 positively selected ARGs and VirGs in periodontitis patients were found in the genomes of respiratory tract pathogens.Of note,91.8％of the background VirGs with at least one non-synonymous single-nucleotide polymorphism for natural selection were also from respiratory tract pathogens.These observations suggest a potential association between periodontitis and respiratory infection at the gene level.Our study enriches the knowledge of pathogens and functional pathways as well as the positive selection of antibiotic resistance and pathogen virulence in periodontitis patients,and provides evidence at the gene level for an association between periodontitis and respiratory infection.

Objective:To compare the efficacy and safety of Changsulin ? with Lantus ? in treating patients with type 2 diabetes mellitus (T2DM). Methods:This was a phase Ⅲ, multicenter, randomized, open-label, parallel-group, active-controlled clinical trial. A total of 578 participants with T2DM inadequately controlled on oral hypoglycemic agents were randomized 3∶1 to Changsulin ? or Lantus ? treatment for 24 weeks. The efficacy measures included changes in glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), 2h postprandial plasma glucose (2hPG), 8-point self-monitoring of blood glucose (SMBG) profiles from baseline, and proportions of subjects achieving targets of HbA1c and FPG. The safety outcomes included rates of hypoglycemia, adverse events (AEs) and anti-insulin glargine antibody. Results:After 24 weeks of treatment, mean HbAlc decreased 1.16% and 1.25%, FPG decreased 3.05 mmol/L and 2.90 mmol/L, 2hPG decreased 2.49 mmol/L and 2.38 mmol/L in Changsulin ? and in Lantus ?, respectively. No significant differences could be viewed in above parameters between the two groups (all P>0.05). There were also no significant differences between Changsulin ? and Lantus ? in 8-point SMBG profiles from baseline and proportions of subjects achieving the targets of HbA1c and FPG (all P>0.05). The rates of total hypoglycemia (38.00% and 39.01% for Changsulin ? and Lantus ?, respectively) and nocturnal hypoglycemia (17.25% and 16.31% for Changsulin ? and Lantus ?, respectively) were similar between the two groups (all P>0.05). Most of the hypoglycemia events were asymptomatic, and no severe hypoglycemia were found in both groups. No differences were observed in rates of AEs (61.77% vs.52.48%) and anti-insulin glargine antibody (after 24 weeks of treatment, 6.91% vs.3.65%) between the two groups (all P>0.05). Conclusions:Changsulin ? shows similar efficacy and safety profiles compared with Lantus ? and Changsulin ? treatment was well tolerated in patients with T2DM.
