ABSTRACT
Objective:To investigate the impact of malnutrition diagnosed with Global Leadership Initiative on Malnutrition (GLIM) criteria on the outcomes of patients with primary gastrointestinal lymphoma (PGIL).Methods:Patients with PGIL admitted into Gansu Provincial People's Hospital from January 2014 to July 2022 were retrospectively enrolled. Nutritional risk screening was conducted using Nutritional Risk Screening 2002 (NRS 2002) scale, and malnutrition was diagnosed as per GLIM criteria. Kaplan-Meier survival analysis and multivariate Cox regression analysis were performed to investigate the effect of malnutrition as per GLIM criteria on the outcomes of PGIL patients.Results:A total of 82 patients were included. The phenotypic parameters, including body mass index (BMI), arm circumference, leg circumference and grip strength, were at significantly lower levels in the 28 malnourished patients, compared with the other non-malnourished patients. The median overall survival of patients with malnutrition as per GLIM criteria was 10 months, while that of patients without malnutrition was 41 months, showing significant differences between groups. The univariate analysis revealed that age, loss of muscle mass, tumor stage based on Lugano classification and malnutrition as per GLIM criteria were the impacting factors for survival in patients with PGIL. The multivariate analysis further demonstrated that tumor stage based on Lugano classification and malnutrition as per GLIM criteria were the independent impacting factors for survival in patients with PGIL.Conclusion:Malnutrition based on GLIM criteria is an independent risk factor for unfavorable outcomes in patients with PGIL and could be utilized as a prognostic indicator.

ABSTRACT
OBJECTIVE@#To investigate the protective effect of vitamin D (VD) against hyperoxia-induced bronchopulmonary dysplasia (BPD) in newborn mice and explore the mechanism.@*METHODS@#Thirty-six newborn mice were randomly divided into air + VD group, air + saline group, hyperoxia + VD group, and hyperoxia + saline group. In all the groups, saline or VD was administered on a daily basis intramuscular injection. After 3 weeks of treatment, the mice were weighed and cardiac blood was collected for measurement of serum VD level using ELISA, and histological examination of the lungs was performed. Radial alveolar counting (RAC) and alveolar secondary interval volume density were measured using image analysis software. The expression levels of vascular endothelial cell growth factor (VEGF) and VEGF receptor 2 (VEGFR2) in the lung tissues were detected using Western blotting.@*RESULTS@#The weight gain rate of the mice and the weight of the lungs were significantly higher in air + saline group and air + VD group than in the hyperoxia + saline group. The RAC was significantly lower in hyperoxic+saline group than that in hyperoxia+VD group ( < 0.001), and was significantly higher in hyperoxic+VD (125 times) than in hyperoxia + VD (1250 times) group ( < 0.01). The alveolar secondary protrusion count was significantly higher in hyperoxic+VD (1250 times) group than in hyperoxic+saline group ( < 0.001), and was significantly higher in hyperoxia+VD (125 times) group than in hyperoxia + VD (1250 times) group ( < 0.01). Compared with that in air + saline group, VEGFR2 expression was significantly lowered in hyperoxia+saline group ( < 0.05) and in air+VD group ( < 0.05); VEGFR2 expression was significantly higher in hyperoxia+VD (1250 times) group than in hyperoxia+saline group ( < 0.001) and hyperoxia+VD (125 times) group ( < 0.001); VEGFR2 expression was significantly higher in hyperoxia+VD (125 times) group than in hyperoxia+ saline group ( < 0.05).@*CONCLUSIONS@#In newborn mice with BPD, VD supplement can increase the weight of the lungs and promote lung maturation, and a higher concentration of VD can better protect the lungs and promote the growth of pulmonary blood vessels.

Endoscopic retrograde cholangiopancreatography (ERCP) is an irreplaceable measure with minimally invasive diagnosis and treatment of endoscopy for biliary and pancreatic diseases, but the related complications associated with ERCP are the highest among the endoscopic procedures. Post-ERCP pancreatitis (PEP) is one of the most common complications with life-threatening in severe cases. Early active prevention can effectively reduce the incidence of post-ERCP pancreatitis. At present, measures including preoperative rectal non-steroidal anti-inflammatory drugs and prophylactic pancreatic stent placement, have definite effective strategy in clinic. Aggressive hydration with lactated Ringer's solution is also a safe and effective way to prevent PEP.

The fourth generation poly( amidoamine) dendrimers ( G4. 0 PAMAM) functionalized multiwalled carbon nanotube ( G4 . 0-MWCNTs ) was prepared by amidation between carboxylated multiwalled carbon nanotube (MWCNTs) and G4. 0 PAMAM. Then a novel hydrogen peroxide (H2O2) sensor was fabricated by electrodepositing Pd nanoparticles (NPs) on a glassy carbon electrode (GCE) modified with G4. 0-MWCNTs composites. The modified electrode was characterized by field emission scanning electron microscopy ( FESEM) , cyclic voltammetry ( CV) and electrochemical impedance spectroscopy ( EIS) . A large amounts of highly dispersion PdNPs could be well loaded on the surface of the G4. 0-MWCNTs, and the modified electrode exhibited excellent electrocatalytic activity towards the reduction of H2 O2 . Under the optimized conditions, the reduction peak currents of H2 O2 were linear to their concentrations in the range from 1. 0 × 10-9 mol/L to 1. 0×10-3 mol/L and the limit of detection of 2. 3×10-8 mol/L was obtained. The recovery of standard addition for human serum samples was 96 . 7%-103 . 1%.
ABSTRACT
ObjectiveTo understand the detections of influenza A (H1N1) in 2009,and haemagglutinin (HA) gene mutations and the comparisons with standard strains.MethodsThe nasopharyngeal swabs from patients with influenza-like illness (ILI) in National Influenza Sentinel Surveillance Hospital and the outbreak epidemic area were collected.The virus typing and A (H1N1) viruses were tested by real time-polymerase chain reaction (RT-PCR).Then the pathogens were isolated with MDCK cells,the virus titer was determined with hemagglutination test and the virus typing was identified with hemagglutination inhibition test (HA1).The RT-PCR products of HA1 gene of virulent strains were sequenced and then analyzed through bioinformatics.Results A total of 996 pharyngeal swab specimens were tested,and nucleic acid positive cases included 337 A (H1N1) subtype,1 seasonal A (H1N1) subtype,67 A (H3N2) subtype,and 12 B type.The positive rate of nucleic acid detection of influenza was 41.87％ and that of A (H1N1) was 33.84％.Thirty-six influenza A (H1N1) virus strains were isolated,and 10 of them were successfully sequenced and several amino acid mutations were identified.There were 6 amino acid mutations found compared with vaccine strain A/California/07/2009 (H1N1),and 1 site was in area B of epitope.Conclusions A (H1N1) is absolute predominant among isolated strains in 2009.HA gene of virulent strains is mutated compared with vaccine strain provided by World Health Organization,which shows that the area B of epitope changes,while the key amino acid position 222 doesn't change.

ABSTRACT
Objective To investigate the predisposing factors of urinary tract infection(UTI) with extendedspectrum beta-lactaraase(ESBLs) producing Escherichia Coli(E. coli) and its resistance to antimicrobial agents.Methods 26 cases of UTI patients with ESBLs producing E. coli from 2003 to 2005 in our hospital were analyzed retrospectively and compared with the ESBLs non-producing strains. Results 88.5 % of the patients with UTI in ESBLs producing E. coli had received broad-spectrum antimierobial therapy before the diagnosis, 69.2 % of the patients were complicate UTIS, 42.3 % of the patients experienced invasive operations in urinary tract; the incidence of drug resistance of ESBLs producing bacteria to the second, third-generation cephalosporins and quinolone was significantly higher than that of ESBLs non-producing bacteria, but it was highly sensitive to imipenem. Conclusion The drug resistance of ESBLs producing E. coli is severe gradually. So much attention should be paid to the ESBLs producing bacteria detection in UTIs. Antimicrobial therapy should be initiated under the guidance of drug sensitivity test,it is necessary to rid the predisposing factors of UITs as much as possible in order to decrease ESBLs-producing bacteria infection.
