ABSTRACT
Objective To observe the correlation of intrapulmonary TREM-1 with endoplasmic reticulum stress in mice with acute lung injury (ALI).Methods Balb/c mice were tracheally injected with lipopolysaccharide(LPS,5 mg/kg) to induce ALI.Real-time PCR and Western blot were used to detect the expressions of TREM-1,CHOP and GRP78.The correlation of TREM-1 with endoplasmic reticulum-related proteins was analyzed.LPS (100 ng/mL) was used to induce inflammation in mouse primary peritoneal macrophages,and expressions of TREM -1,CHOP and GRP78 mRNA were detected by real-time PCR.The effect of TREM-1 activation on the expressions of CHOP and GRP78 was observed in macrophages.Results The expressions of TREM-1,CHOP and GRP78 mRNA were increased in ALI mice.TREM-1 mRNA expression was positively correlated with CHOP and GRP78 mRNA expression.In vitro,LPS up-regulated the expressions of TREM-1,CHOP and GRP78,and TREM-1 was positively correlated with CHOP and GRP78.Activation of TREM-1 increased CHOP and GRP78 mRNA expressions.Conclusions TREM-1 is positively related to the endoplasmic reticulum stress.The activation of TREM-1 enhances endoplasmic reticulum in mouse macrophages.
ABSTRACT
Objective To understand the management status quo of migrant workers with chronic hepatitis B (CHB) to ex‐plore the management countermeasures and improve the survival quality for tamping the foundation of the healthy project .Methods Totally 300 migrant workers with CHB were performed the living quality evaluation and investigation on the service needs ,com‐pliance ,economic condition ,categories and proportion of reimbursement by adopting the supplementary revision of SF‐36 living quality scale and general information questionnaire ;the influencing factors of their living quality were performed the univariate anal‐ysis and multivariate stepwise regression analysis .Results The statistical analysis found that whether convenient for outside visit‐ing hospital ,categories and proportion of reimbursement ,whether normalized antiviral therapy ,whether conducting examination and follow up at regular intervals and liver disease specific symptoms were the influencing factors of living quality in the migrant work‐ers with CHB(P<0 .05);the living quality in the patients with outside convenient visiting hospital ,high reimbursement proportion , normalized antiviral therapy and examination and follow up at regular intervals was significantly higher than that in the patients with inconvenient outside visiting hospital ,low reimbursement proportion ,non‐normalized anti‐viral therapy and examination and follow up without regular intervals(P<0 .05);the liver disease specific symptom score showed the positive correlation trend with the living quality score (B=7 .657 ,SD=2 .650 ,t=2 .889 ,P=0 .004) .Conclusion It is necessary to improve the patient′s medical needs ,reimbursement type and proportion ,increase the compliance of patient′s normalized examination and follow‐up at regular in‐tervals and standard antiviral treatment ,thus to realize the standardized examination and treatment in CHB patients ,prevent or de‐lay the disease progression ,avoid liver cirrhosis and decompensated hepatopathy ,reduce the occurrence of HCC ,improve the quality of life and prolong the survival period .
ABSTRACT
To employ multiplex polymerase chain reaction (PCR) to classify the types of virus in 128 patients of community-acquired pneumonia and analyze the relationship between type of virus,age and seasons.The positive rate of viral pneumonia was 34.4％ (44/128).In 44 virus positive patients,the rates of influenza A virus,rhinovirus,adenovirus,parainfluenza type 1,human metapneumovirus virus,influenza B virus,parainfluenza type 2,parainfluenza type 3 and enterovirus were 22.7％ (10/44),15.9％ (7/44),15.9％ (7/44),9.1％ (4/44),9.1％ (4/44)6.8％ (3/44),2.3％ (1/44),2.3％ (1/44) and 2.3％ (1/44) respectively.And other 6(13.6％) patients were at least infected by one virus.The viral pneumonia had a high positive rate in spring and winter.And the age group of 20 to 29 years had a high positive rate.The major pathogen contributing to adult community-acquired pneumonia in Yantai were influenza A virus,rhinovirus and adenovirus.
ABSTRACT
Objective To investigate the changing trend of incidence and the relevant factors in fetal macrosomia. Methods 84 883 newborns during Jan. 1,1970 to Dec. 31,1999 were used to analyze the incidence of fetal macrosomia,the average birth weight,the percentage of superior fetal macrosomia, the distribution of gestational age, the rate of cesarean section and the vaginal delivery, the relevant factors of fetal macrosomia. Results All the cases were divided into 3 groups, one group from 1970 to 1979, the second one from 1980 to 1989, the third one from 1990 to 1999. The incidence of fetal macrosomia for three groups were 2. 6%, 6. 9% and 13 2% ( P
