Objective To analyze the clinical characteristic and prognosis of Serratia infections in newborn infants and increase awareness of Serratia infections.Methods The clinical manifestations,diagnosis,complications,treatment and prognosis of Serratia infections were analyzed in 4 hospitalized newborn infants in neonatology center from Jul.2008 to Feb.2009.Results Among the 4 cases,blood culture revealed Serratia marcescens in 3 cases(1 case was preterm infant),cerebral spinal fluid culture revealed Serratia liquefacien in the fourth case.The main clinical manifestations were fever,convulsion and poor response,WBC and CRP were much higher,while obvious thrombocytopenia was only found in the preterm infant.Two cases of septicemia infection alone recovered after the treatment of the third-generation cephalosporin for at least 2 weeks,while the other 2 cases of septicemia infection combined with purulent meningitis,included 1 case of preterm infant and 1 case of Serratia liquefacien infection,developed meningoencephalitis and brain abscess confirmed by serial imaging,both of which had poor neurological sequelaes.Conclusions As a opportunistic pathogen,Serratia can cause severe infection in newborns.The patients complicated with meningitis should be followed up and pay more attention to the high incidence of neurological sequelaes.

· AIM: To explore the dynamic expression and correlation among telomerase catalytic subunit (TERT), proliferating cell nuclear antigen ( PCNA) and antiapoptosis protein Bd-2 which relate to cell proliferation in epiretinal membrane of rat traumatic proliferative vitreoretinopathy(PVR).· METHODS: S-P technique was applied for immunohistochemical staining of epiretinal membrane of traumatic PVR with TERT, PCNA and Bcl-2 antibody. HE staining was also carried out. The staining results were analyzed with image analysis system.· RESULTS: The positive rate and average A of PCNA protein were upregulated at first and then down-regulated, with the peak value in 14d Group, which was significantly different from those in 7d Group and 28d Group.The positive rate and average A of TERT and Bcl-2 were also upregulated at first and then down-regulated, with the peak value in 14d Group and 21d Group, which were significantly different from those in 7d Group. There was significant correlation among PCNA, Bcl-2 and TERT protein expression (P≤0.01).· CONCLUSTON: TERT and Bcl-2 take part in the regulation of proliferative cells in epiretinal membrane of traumatic proliferative PVR, with high correlation with the dynamic changes of cell proliferation.

Objective To investigate the changes in tumor necrosis factor-α(TNF-α) and plasminogen activator inhibitor(PAI) in the presence of obstructive sleep apnea syndrome(OSAS) in patients with type 2 diabetes mellitus,and to investigate if that 2 inflammatory factors is associated with hypoxemia during sleep.Methods Fiftyfour patients with type 2 diabetes mellitus hospitalized for glycemic control were subgrouped into 27 patients with OSAS (group O) and 27 patients without OSAS (group N).26 people without diabetes and OSAS were selected from a health check-up program to serve as control group (group C).Serum TNF-α and PAI levels were measured by commercial ELISA kits.Apnea hypopnea index (AHI),the lowest pulse oxygen saturation (LSpO2) at night were detected by portable sleep monitor.The relativity regarding TNF-α,PAI,homeostasis model assessment for insulin resistance (HOMA-IR),fasting blood glucose(FBG),AHI,LSpO2,and age was discussed.TNF-α and PAI were regard as dependent variables,and FBG,HOMA-IR,AHI,LSpO2,and age as independent variables in multivariate stepwise linear analysis.Results The levels of HOMA-IR,TNF-α,PAI in group O [2.69 ± 1.53,(1.97 ±0.13) ng/ml,and (2.27 ± 0.85) ng/ml] were higher than the those in other 2 groups,and those in group N [1.70 ± 0.88,(1.09 ±0.29) ng/ml,and (1.59 ± 0.13) ng/ml] were higher than group C [1.15 ± 0.67,(0.73 ± 0.19) ng/ml,and (0.89 ±0.25) ng/ml].The levels of FBG in the 2 diabetic groups were higher than those in group C.The level of AHI in group O was higher than that in group N and group C,while LSpO2 in group O was lower than that in group N and group C.Spearman univariate analysis showed that TNF-α and PAl both were associated positively with HOMA-IR,FBG,and AHI,while negatively with LSpO2.Multivariate stepwise linear analysis denoted that TNF-α was independently associated with AHI,FBG,while PAI was independently associated with AHI and HOMA-IR.Conclusions Patients with diabetes and OSAS manifest raised level of chronic inflammatory activity,and therefore,OSAS might be implicated in the pathogenesis of chronic complication of patients with type 2 diabetes.

OBJECTIVETo construct a eukaryotic expression vector for expressing hepatitis C virus (HCV) recombinant NS5B-EGFP fusion protein and obtain a stable transfected HepG2 cell line.

METHODSThe coding region of NS5B gene of HCV was amplified by PCR and was digested by Xho I/Kpn I. This fragment was inserted into pEGFPN3 with T4 ligase and transformed E. coli TG1. The positive recombinant plasmid was selected, then the recombinant plasmid was transfected into HepG2 cell by Lipofectin AMINE 2000. Cells containing stable transformants were selected by the ability of resistance to G418 and isolated with a limited dilution. The stable transfected cell line expressing high level NS5B-EGFP fusion protein was obtained.

RESULTSThe eukaryotic expression vector named pEGFPN3-ns5b was successfully constructed and the stable transfected HepG2 cell line expressing NS5B-EGFP fusion protein was obtained.

CONCLUSIONThe stable transfected HepG2 cell line could express NS5B-EGFP fusion protein, could be used for anti-HCV infection with ns5b gene as the target.

Objective To observe the influence of traditional Chinese Medicine (TCM) Five-element music combined with language induction on the psychological status and quality of life among maintenance hemodialysis patients. Methods A total of 66 maintenance hemodialysis patients were divided into the Five-element music group (n=34) and the routine care group (n=32) according to date of hemodialysis. The routine group accepted routine care. The music group accepted the intervention of traditional Chinese Medicine Five-element music combined with language induction on the basis of routine care. Four weeks later, the changes of Hospital Anxiety Depression Scale (HAD), the MOS item Short From Health Survey (SF- 36) were observed to assess the effect before and after the intervention. Results HAD comparison in the group: After 4-week intervention, in Five-element music group, the depression and anxiety score of HAD and HAD total score were 3, 5, 9 (meadian score), which had improved significantly than before, which were 4, 7, 12 (meadian score), the difference was significant (Z=-2.645,-2.927,-3.220, P<0.01) . After 4 weeks, in the routine group the depression and anxiety score of HAD and HAD total score showed no significant change than before (P>0.05). SF-36 comparison in groups: After 4-week intervention, in Five-element music group, the physical, physiological function,overall health, energy status, social function, emotional function, mental health factors of SF-36 scored 63, 88, 74, 41, 75, 75, 100, 80 (meadian score), which had improved significantly compared with before, which were 45, 0, 68, 40, 58, 75, 17, 72 (meadian score), the difference was significant (Z=-3.895--2.027, P<0.01 or 0.05), body pain and mental health factors had no significant difference (t=-1.785,-1.576, P>0.05). After 4 weeks, the routine group′s each factor score had no significant difference compared with before (P > 0.05). Conclusions TCM Five-element music has a certain effect on improving the psychological status and the quality of life of the patients in maintenance hemodialysis.
