Objective To understand the relationship between childhood non-intentional injury and socio-economic status (SES) in Jiangxi province. Methods Nearly 100 000 households were selected by PPS sampling method, in Jiangxi province. All children aged 0-17 years in selected households were surveyed using an 'injury questionnaire'. SES was calculated under the World Bank method. Results 98 335 children were surveyed and the identified number of non- intentional injury cases was 5429 and with 52 fatal cases. The morbidity was 5.52% and mortality was 52.88/100 000. The mortality of children with higher SES was lower than that of other groups but without statistical significance. The morbidity of moderate injury increased with the increasing SES, also without statistical significance. However, the morbidity of severe injury in male children decreased with the increasing SES. Rates of moderate injury morbidities of fall and road traffic injury also increased with the increasing SES. Moderate injury morbidity caused by animals decreased with the increasing SES. Severe injury morbidity of fall decreased with the increasing SES. Conclusion The morbidity of injury in children was affected by the SES and the relationship between injury and SES varied along with the results of different types of injuries.

This study reported the analysis of plasma phospholipid metabolism of the rats and the pathological biomarkers between the type 2 diabetes model control group (MC) and the normal control group (NC). SD rats were randomly divided into 2 groups: NC and MC. To investigate state of plasma metabolite profiling in normal body, type 2 diabetes mellitus (T2DM) model group using UPLC-Q-TOF/MS which was used as analysis tool in this research. The compounds were identified by UPLC-Q-TOF/MS based on MS/MS fragment ions information, element composition in MassLynx 4.1 and the Lipid Maps database. The sign of two groups of samples in specific markers for screening was through a software package in R software (BioMark software). The results show that the pathological markers were mainly phosphatidylcholine (PC) and triglycerides (TG); the 2-acyl PC in the MC group was less more obviously than that in the NC group; high carbon number and high degree of unsaturation of the TG was reduced under the condition of type 2 diabetes. In the state of type 2 diabetes, metabolic changes occurred in rat plasma phospholipids obviously, which had a close relationship with the occurrence and development of T2DM.

Objective:To investigate the prognosis and outcome of patients with chronic hepatitis C (CHC) related cirrhosis after achieved sustained virologic response (SVR) treated with direct-acting antiviral agent (DAA).Methods:Ninety-five patients diagnosed with CHC related cirrhosis who had complete data in Tianjin Second People′s Hospital from January 2014 to June 2017 were retrospectively followed up. Among them, 72 patients were treated with DAA and all of them achieved SVR, and the other 23 patients did not receive any antiviral therapy. The differences of mortality and incidence of hepatocellular carcinoma (HCC) between DAA treatment group and non-antiviral treatment group were compared. Statistical analysis was performed by independent sample t test, Mann-Whitney U test and chi-square test. Results:At the end of follow-up for three to 71 months, patients in DAA treatment group had a significant improvements in alanine aminotransferase, aspartate aminotransferase, albumin and liver stiffness measurement compared with those before treatment (42(23, 61) U/L vs 18(13, 28) U/L, 54(37, 75) U/L vs 23(18, 28) U/L, 39(33, 42) g/L vs 45(41, 48) g/L, 26(18, 37) kPa vs 15(11, 26) kPa, respectively, Z=-6.005, -7.008, -6.057 and -3.162, respectively, all P<0.01). However, there were no significant differences in incidence of HCC (12%(9/72) vs 17%(4/23)) and mortality (3%(2/72) vs 13%(3/23)) between the DAA treatment group and non-antiviral treatment group (both P>0.05). There was no significant difference of cumulative incidence of HCC in DAA treatment group compared with non-antiviral treatment group ( P=0.609). The age of patients progressed to HCC was older than those without HCC ((60.3±3.6) years vs (54.4±9.9) years, t=-3.948, P<0.01). In subgroup analysis, among the six patients with HCC, four had diabetes, the prevalence of diabetes in the patients without HCC was 17%(7/42); the level of fasting blood glucose (FBG) ((7.3±1.9) mmol/L vs (5.9±1.1) mmol/L) were higher in patients progressed to HCC than those without HCC in DAA treatment group with compensated cirrhosis ( χ2=7.430 and t=-2.442, respectively, both P=0.019). Conclusions:DAA treatment could notably improve liver function and alleviate liver fibrosis, but could not reduce the mortality and incidence of HCC in patients with CHC related cirrhosis significantly. Diabetes and high level FBG may be the risk factors for occurrence of HCC in patients with CHC related compensated cirrhosis.

OBJECTIVETo explore the morbidity, mortality, and disease burden of traffic injury in children aged 0-17 years so as to develop a related strategy on prevention.

METHODS100,000 households were selected by PPS sampling method in Jiangxi province. All children aged 0-17 years in selected households were interviewed by trained interviewers using a standardized 'traffic injury questionnaire'.

RESULTSThe overall mortality and fatality rates of traffic injury were 10.17/100,000 and 1.36% respectively while the traffic injury morbidity in children of 0-17 years old was 7.40 per thousand. Morbidity in males was 8.29 per thousand compared to 6.26 per thousand in females. Severe cases accounted for 1.79 per thousand of the total but those living in urban area appeared to be 0.93 per thousand compared to 1.88 per thousand in the rural area, with statistical significance. Pedestrian and cyclists related injuries accounted for 80.48% of all the injured children. The average medical cost per case was 1369.57 Yuan with an average of 3.63 days of hospitalization. The average days of missing school/working was 8.79.

CONCLUSIONThe morbidity and mortality among male children were higher than those among female children. The morbidity of severe traffic injury cases in children living in rural area was higher than that of children living in urban area. The disease burden of traffic injury in Jiangxi province was heavy and the development of relative intervention strategy seemed urgent in Jiangxi province.

Objective To investigate the expression and distribution of Cdc42-interacting protein 4 (CIP4) in renal fibrotic tissue,and the interaction between CIP4 and β-catenin in transforming growth factor β1 (TGF-β1)-induced epithelial-mesenchymal transition (EMT) model of HK-2 cell line.Methods In vivo,the model of renal fibrosis was induced by 5/6 subtotal nephrectomy in rat.Masson staining was used to evaluate the level of renal tissue fibrosis.The expression and distribution of CIP4 was detected by immunohistochemistry.In vitro,the EMT model of HK-2 cell line was induced by TGF-β1 (10 μg/L) for 72 h.Western blotting was used to observe the expression of E-cadherin,β-catenin,CIP4 and α-SMA.Colocalization and interaction of CIP4 and β-catenin were detected by immunofluorescence and immunoprecipitation respectively.Results Compared to sham group,CIP4 expression was increased in group of 5/6 subtotal nephrectomy,CIP4 was mainly distributed in basolateral side of renal tubular epithelia.In vitro,expressions of α-SMA and CIP4 were increased in HK-2 cells stimulated by TGF-β1 for 72 h (2.5and 1.8 folds,respectively) (all P＜0.05),expression of E-cadherin was decreased(P＜0.05).Partial colocalization between CIP4 and β-catenin was detected by immunofluorescence.In control group,CIP4 and β-catenin partially colocalized at the cell membrane.Mter the stimulation of TGF-β1,translocation to nucleus of CIP4 and β-catenin were increased,and partially colocalized in nucleus.The interaction between CIP4 and β-catenin was observed by immunoprecipitation in both control and TGF-β1 stimulated groups.Conclusions Expression of CIP4 in renal fibrotic tissue is increased,which is mainly distributed in basolateral side of renal tubular epithelia.CIP4 and βcatenin partially colocalize and interact with each other.CIP4 may play a role in EMT process through the interaction with β-catenin.

The HLA system was discovered by virtue of the fact that it was polymorphic. The impetus for its discovery was the search for polymorphic antigens to match for transplantation, by analogy with the human red cell blood groups. The most usually DNA method of HLA typing is sequence specific oligonucleotides (SSO) and PCR sequence specific primers (SSP). SSO technique is perfectly suited for analyzing large number of samples, it is not suitable for individual or small numbers. The SSP method is ideal for typing individual samples, but it is costly and requires high capacity thermal cycles for larger numbers of samples. To set up a simple, quick, cheap and high resolution DNA method, were collected sixty-three cord blood samples from Guangzhou Cord Blood Bank, got DNA from blood by the traditional guanidine hydrochloride distillation method. Each sample was simultaneously typed by SSOP, PCR-SSP and reverse dot-blot hybridization (RDB) methods. All of typed is success. The results of three DNA methods are consistent each other. 60 HLA-DRB1 alleles could be accurately distinguished with the RDB method. Our results show that RDB method is a simple, quick, cheap and high resolution method for HLA-DRB types. It can be used in any HLA typing.

To express interesting human genes in herbal cells for boosting their specific pharmacological activities, RANTES gene cloned from human peripheral blood lymphocyte (PBL) mRNA was introduced into A. tumefaciens strain LBA4404 harboring pAL4404 plasmid via tumor-inducing (Ti) plasmid-derived intermediate expression vector pROKII. In vitro cultured P. vulgaris cells were transformed by leaf-disk cocultivation procedure. Integration of RANTES gene in the genome of transformed cells was confirmed by Southern blotting, and expression of RANTES gene in transformed cells was analyzed by RT-PCR amplification, Western blotting and enzyme-linked immunosorbent assay (ELISA). The peroxidase activity of PBL was utilized as a detection index of cellular chemotropism induction by recombinant RANTES. The results have shown the RANTES gene was integrated in transgenic P. vulgaris cells, and RANTES gene-stably expressed cell clones were available, which could pave the way to obtain transgenic P. vulgaris plants demonstrating specific pharmacological activities.
