OBJECTIVE:To investigate the efficacy of rosiglitazone in the treatment of patients with nonalcoholic fatty liver(NAFLD).METHODS:A total of 124 patients with NAFLD(excluding those with cirrhosis) were randomly divided into rosiglitaone(RSG) treatment group and placebo group(control) for a treatment of 24wk.Then the curative effects in two groups were compared.RESULTS:As compared with placebo,RSG showed a better efficacy in the improvement of the liver function,levels of blood glucose and blood lipid(P

Objective To investigate the level of professional commitment of student nurses,and explore the impact of student nurses' role conflict and role ambiguity on their professional commitment.Methods From May to June 2014,totally 320 student nurses from a third-level hospital in Tianjin were recruited in this study.And Role Stress Scale and Nursing Professional Commitment Scale were used in the investigation.Results The total score of role stress of student nurses was (44.29±5.53) scores,and the total score of professional commitment of student nurses was (86.12±14.14) scores.Pearson correlation analysis and multiple linear regression analysis showed that student nurses' role conflict was positively correlated with professional commitment,but their role ambiguity was negatively correlated with professional commitment.Conclusion School and hospital managers should adopt effective measures to relieve student nurses' role ambiguity and guide the correct understanding of role conflict to maintain a stable nursing team.

Objective To explore the risk factors on cases regarding work-related acute pesticide poisoning among farmers of Jiangsu province.Methods A population-based,1 ∶ 2 matched case-control study was carried out,with 121 patients as case-group paired by 242 persons with same gender,district and age less then difference of 3 years,as controls.Cases were the ones who had suffered from work-related acute pesticide poisoning.A unified questionnaire was used.Data base was established by EpiData 3.1,and SPSS 16.0 was used for both data single factor and multi-conditional logistics regression analysis.Results Results from the single factor logistic regression analysis showed that the related risk factors were:lack of safety guidance,lack of readable labels befores praying pesticides,no regression during application,using hand to wipe sweat,using leaking knapsack,body contaminated during application and continuing to work when feeling ill after the contact of pesticides.Results from multi-conditional logistic regression analysis indicated that the lack of safety guidance (OR=2.25,95％ CI:1.35-3.74),no readable labels befores praying pesticides (OR=1.95,95％ CI:1.19-3.18),wiping the sweat by hand during application (OR=1.97,95％CI:1.20-3.24)and using leaking knapsack during application (OR=1.82,95％ CI:1.10-3.01) were risk factors for the occurrence of work-related acute pesticide poisoning.Conclusion The lack of safety guidance,no readable labels befores praying pesticides,wiping the sweat by hand or using leaking knapsack during application were correlated to the occurrence of work-related acute pesticide poisoning.

Objective To determine the association of gallstone,cholecystectomy and colorectal cancer.Methods From 2000 through 2007,a historical cohort study was carried out in the check analysis of the cumulative incidence of colorectal cancer of 3809 gallstone patients who had had cholecystectomies (cholecystectomy sub-group),1764 gallstone patients who had not had cholecystectomies(noncholecystectomy sub-group)and 8187 nongallstone patients(control group)were also included in the analysis of the incidence of colorectal cancer.Results(1)The cumulative incidence of colorectal cancer of the gall-stone group was 0.43 ％(24/5573)while that of the control group was 0.13 ％(11/8187)(x2 =11.879,P =0.001).(2)The cumulative incidence of colorectal cancer in cholecystectomy sub-group was 0.45％(17/3890)while that of the non-cholecystectomy sub-group was 0.40％(7/1764)(x2=0.069,P =0.793).(3)The cumulative incidence of colorectal cancer was 0.23％(8/3467)in gallstone patients with a conrse ＜ 15 years,while that was 0.76％(16/2106)when the course ≥ 15 years(x2 =8.550,P =0.003).(4)Serum triglyceride level elevated in 20.83％(5/24)colorectal cancer cases of gallstone group,however serum triglyceride level elevated only in 5.86％(325/5549)of gallstone group with non-colorectal cancer cases(x2 =9.621,P =0.002).(5)The incidence of colorectal cancer in gallstone group was not related to gender,age,overweight,hypertension,diabetes mellitus and dysfunction of liver(x2 =1.444,P =0.229;x2=7.833,P=0.251;x2 =1.151,P=0.283;x2 =0.797,P=0.372;x2 =0.939,P=0.332;x2 =2.103,P =0.147).(6)The ratio of rectal cancer,right colonic cancer,left colonic cancer and multifocal carcinoma were 41％(10/24),38％(9/24),17％(4/24)and4％(1/24),respectively.Conclusions Gallstone is a high risk factor of colorectal cancer irrespective of whether or not a cholecystectomy is carried out.Over fifteen-years course of gallstone and hypertriglyceridemia significantly increases the risk of the colorectal cancer in gallstone patients.The incidence of rectal cancer and right colonic cancer is more frequently seen in gallstone related colorectal cancer.

OBJECTIVETo describe the clinical features, treatments and prognosis of very low birth weight infants (VLBWIs) requring mechanical ventilation, to assess the risk factors associated with the mortality of VLBWIs, and to evaluate the significance of the scoring system based on clinical risk index for babies (CRIB) and the score for neonatal acute physiology-perinatal extension II (SNAPPE-II) for predicting mortality risk for premature infants in China.

METHODSPerinatal data were collected from 127 VLBWIs requring mechanical ventilation who were admitted to the neonatal intensive care unit (NICU) from January 2010 to October 2011.

RESULTSThe enrolled infants had a mean gestational age of 31±2 weeks, a mean birth weight of 1290±170 g, a male/female ratio of 1.23∶1, and extremely low birth weight infant accounting for 6.3%. Of the 127 cases, 48.0% were administered with pulmonary surfactant (PS), and 49.6% received endotracheal intubation ventilation. The overall in-hospital mortality was 41.7%. Multivariate logistic regression revealed the following independent risk factors for mortality: low birth weight, multiple birth, cesarean section, and low PaO2/FiO2 ratio (OR = 1.611, 7.572, 4.062, and 0.133 respectively; P<0.05). SNAPPE-II and CRIB showed good performance in predicting prognosis, with areas under the ROC curve of 0.806 and 0.777 respectively.

CONCLUSIONSThe overall mortality rate of VLBWIs is still relatively high. The high-risk factors for VLBWI mortality include low birth weight, multiple birth, cesarean section, and low PaO2/FiO2 ratio. The neonatal illness severity scoring system (using SNAPPE-II and CRIB) can be used to quantify illness severity in premature infants.

Objective To explore the effect of vitamin D hormone(VDH)on autophagy and apoptosis in hippocampus of rats with traumatic brain injury(TBI). Methods A total of 45 male Sprague-Dawley rats were divided into control group(n=15),model group(n=15)and VDH group(n=15).The TBI model was established in the model group and VDH group.VDH group was injected with VDH 1 μg/kg 30 minutes,24 hours and 48 hours after modeling,respectively.The expression of microtubule as-sociated protein 1 light chain 3(LC3)and p62 was detected with Western blotting,and the number of apoptotic cells were detected with TUNEL three days after modeling.All groups were tested with Morris water maze on the fifth,sixth and seventh days. Results The number of TUNEL positive cells in hippocampus was more in the model group than in the control group (P<0.05),and was lower in VDH group than in the model group(P<0.05),as well as the expression of LC3II/LC3I and p62(P<0.05).The escape latency was longer in the model group than in the control group(P<0.05),and was shorter in VDH group than in the model group (P<0.05). There was no significant difference in the swimming velocity on the fifth,sixth,and seventh days among three groups(F=0.530,P>0.05). Conclusion VDH has potential neuroprotective effects on TBI,which might be associated with its anti-apoptosis effect on the expression of LC3 and p62 proteins in hippocampus after TBI.

Objective:To evaluate effect of diammonium glycyrrhizinate(DG)on lipopolysaccharide(LPS)-induced TLR4/NF-κB inflammatory signaling pathway in BV2 microglial cells and to explore its potential regulatory mechanisms on ameliorating neu-roinflammation.Methods:BV2 microglia injury model was induced by LPS and treated with 20 and 60 μmol/L DG.MTS was used to determine vitality of cells.NO level secreted by cells was detected by Griess.Inflammatory factors TNF-α,IL-6,and IL-1β levels in cell supernatant were measured by ELISA.TNF-α,IL-6,IL-1β,TLR4 and MyD88 mRNA levels were detected by RT-qPCR.Western blot was used to determine expressions of TLR4,MyD88,NF-κB,p-NF-κB,IκB-α and p-IκB-α proteins of cells.Results:Compared with control group,LPS-treated BV2 microglia had significantly lower viability(P<0.05),significantly higher NO secretion(P<0.05),significantly up-regulation levels of inflammatory factors TNF-α,IL-6 and IL-1β(P<0.05),and significantly higher mRNA levels of TNF-α,IL-6,IL-1β,TLR4 and MyD88(P<0.05),TLR4,MyD88,NF-κB,p-NF-κB,IκB-α,and p-IκB-α protein expressions were significantly increased(P<0.05).Compared with LPS group,BV2 microglia intervened with different concentrations of DG had significantly higher viability(P<0.05),significantly lower NO secretion(P<0.05),significantly lower TNF-α,IL-6 and IL-1β inflammatory factors levels(P<0.05),significantly lower mRNA levels of TNF-α,IL-6,IL-1β,TLR4 and MyD88(P<0.05),and TLR4,MyD88,p-NF-κB and p-IκB-α protein expressions were significantly reduced(P<0.05).Conclusion:DG can inhibit LPS-induced neuroinflammatory responses in microglia,whose underlying mechanism is suppression of TLR4/NF-κB signaling pathway.

In accordance with the One Health concept,this study was aimed at exploring research trends and major topics in global zoonotic diseases,and providing suggestions for the prevention and control of zoonotic diseases in China.Using biblio-metric analysis,we analyzed 289 411 relevant articles in the SCIE database from 2012 to 2022 in the field of zoonotic diseases.We conducted in-depth analysis of publication trends,research themes,and cutting-edge topics in the field of zoonotic diseases.The number of publications in the field of zoonotic diseases has significantly increased since 2019.The United States had the most publications in this field,and was followed by China,which has shown strong growth.Further analysis of co-occurrence clustering of keywords in 7 115 highly cited articles in zoonotic diseases in the past 11 years revealed three major research themes:animal health,human health,and environmental health,according to the One Health concept.Keyword evolution a-nalysis showed that zoonotic disease articles were broadly related to issues such as"food safety"and"microbial resistance"in earlier years,whereas"COVID-19,""COVID-19 variants,"and"COVID-19 vaccine"have become recent research hotspots.Practicing the One Health concept and promoting interdisciplinary,interdepartmental,and interregional collaboration are crucial for enhancing the prevention and control of zoonotic diseases in China,thereby safeguarding national security,public health,and ecological safety.
