To investigate the distribution of virulence associated factors of 5 strains of Streptococcus suis type 2 from slaughtered pigs isolated in Fujian province , 7 virulence genes were detected through PCR amplification. They were the glutamate dehydrogenase gene(gdh), the capsular polysaccharides gene(cps), the extracellular factor gene(ef), the muramidate-released protein gene(mrp), the suilysin gene(sly), the fibronectin-binding protein gene(fbps) and the virulence-associated sequence or f2. Among these 5 strains isolated, the virulence genotypes of 4 strains S.suis type 2 and strain SS2PFJ07 was gdh+/cps2J+/mrp+/ef-/sly-/fbps+/orf2+ and the other one strain isolated from slaughtered pigs was gdh+/cps2J+/mrp+/ef+/sly+/fbps+ /orf2+ respectively. This results showed that there are at least 2 virulence genotypes in Streptococcus suis type 2 from slaughtered pigs isolated in Fujian province.

Objective To evaluate the effectiveness of nurse-led discharge planning for hospital inpatients with chronic disease.Methods The Cochrane Library,PubMed,Medline,EMBASE,Chinese Biomedical Literature Database Database(CBM),China National Kmowledge Infrastructure (CNKI),VIP Chinese full text database (VIP) and Wanfang Data were searched for randomized controlled trials assessing nurse-directed discharge planning for hospital inpatients with chronic disease.Two reviewers independently extracted data and assessed risk of bias.Meta-analysis was conducted for the eligible studies by RevMan 5.3.4.Results Seventeen randomized controlled trials and 5 331 participants were included.Meta-analysis demonstrated that,compared to standard care,nurse-led discharge planning were effective in reducing hospital readmission [risk radio (RR)=0.73,95% confidence interval (CI) 0.64-0.84,P<0.01],duration of inpatient readmissions [mean difference (MD)=-2.48,95%CI-3.68--1.29,P<0.01],and all-cause mortality (RR=0.78,95%CI 0.62-0.97,P< 0.05).However,no reduction in the length of stay of the index admission (MD=-0.18,95%CI-0.64-0.27,P > 0.05) was demonstrated.Conclusions Nurse-led discharge planning has a positive impact on several aspects of care for hospital inpatients with chronic disease,including reducing readmission,readmission length of stay,and all-cause mortality.It is worth being popularized.

Objective To explore the correlation between polymorphism of interleukin-28B(IL-28B) rs12979860 T/ C and susceptibility of hepatocellular carcinoma( HCC). Methods All eligible case-control studies published up to 2014-09-30 were identified by searching PubMed,EMBase,CNKI,CBM,VIP and WanFang databases. Two reviews independently identified the literature according to inclusion and exclusion criteria. Meta-analysis was performed using Rev Man 5. 2 and Stata 12. 0 software. Results A total of 6 stud-ies comprising 1 138 cases and 955 controls were finally included. Meta-analysis showed that IL-28B rs12979860 T/ C polymorphism was associated with the susceptibility of HCC. Compared with the genotype CC and CT + CC,genotype TT increased the risk of suffering from HCC(TT vs CC:OR = 2. 26,95% CI:1. 40-3. 64,Z = 3. 33,P = 0. 000 9;TT vs CT + CC:OR = 1. 90,95% CI:1. 23-2. 93,Z = 2. 89,P = 0. 004). In stratification analysis by ethnicity,we observed that the polymorphism of IL-28B rs12979860 T/ C was associat-ed with the susceptibility of HCC among Caucasian populations(TT vs CC:OR = 2. 06,95% CI:1. 22-3. 47, Z = 2. 70,P = 0. 007;TT vs CT + CC:OR = 1. 71,95% CI:1. 07-2. 72,Z = 2. 23,P = 0. 03). Conclusion The polymorphism of IL-28B rs12979860 T/ C is associated with the susceptibility of HCC,genotype TT may increase the susceptibility to HCC.

Objective: To study influence of acute hypoxia on the current of voltage-gated potassium channel (IK) in pulmonary artery smooth muscle cells (PASMC) of rats. Methods: A total of 20 male SD rats were randomly and equally divided into normoxic control group and acute hypoxia group. The rats in acute hypoxia group were kept in hypoxic chamber for 8 h before experiment. Whole cell patch-clamp technique was used to record IK in PASMC. Results: Acute hypoxia significantly decreased the IK density in PASMC of rats. During -60mV to -10mV of resting membrane potential(RMP), acute hypoxia did not significantly decrease peak IK density in PASMC of rats, P>0.05; At 0 mV, acute hypoxia significantly decreased the peak IK density in PASMC [from(38.1 ± 5.2) pA / pF decreased to(9.82 ± 2.1) pA / pF ,P<0.05], then along with RMP increase in PASMC, the decreasing amplitude of peak IK density in PASMC gradually increased(P<0.05); From + 30 mV to+ 60 mV, the decreasing amplitude of peak IK density in PASMC further significantly increased(P<0.01); At + 60 mV the peak IK density decreased from(38.1 ± 5.2) pA / pF to(9.82 ± 2.1) pA / pF , and the decreasing amplitude reached (46.8±3.3)%. Conclusion: Acute hypoxia can decrease Kv current in PASMC of rats, leading to hypoxic pulmonary vasoconstriction.

Hedgehog (Hh) signaling pathway is present in many animals and plays an important role in regulating embryonic development and differentiation. Aberrant activation of Hh signaling contributes to the pathogenesis of many malignancies. Recent studies have shown that dysregulated Hh signaling pathway participates in the tumorigenesis, tumor invasion, and metastasis of hepatocellular carcinoma (HCC). Investigation of the relationship between Hh signaling pathway and HCC will help elucidate the molecular mechanism of pathogenesis of HCC and provide a new insight into the development of novel anticancer therapy and therapeutic target.
