【Objective】To establish a HBV-marker-producing nude mice model of human transplanted liver cancer(HTLC).【Methods】2.2.15 cells,a HePG2 cell line transfected with HBV genome,were injected subcutaneously into athymic BALB/c-nu mice aged 4～6 weeks.The growth of tumor was observed every week.After 36 days the nude mice were executed and HBV markers of HBsAg,HBeAg,and HBV-DNA as well as alpha-fetoprotein(AFP)in serum were detected.The pathological features of tumor tissues were examined under light microscope.【Results】The incidence of HTLC and the time of HTLC appearing were correlated with the number of transplanted 2.2.15 cells.Serum HBsAg,HBeAg,and HBV-DNA were positive in the HTLC transplanted mice,the serum content of AFP was(350?11.5) ?g/L,and pathological changes under light microscope were similar to human,indicating that the model has some similar histological characteristics of the human liver cancer infected by HBV.【Conclusion】The nude mice model of human transplanted liver cancer,which can produce HBV markers,is established successfully in this study.

Objective To investigate the curative effect and nursing of children with cerebral palsy treated by cerebrovascular function treatment(CVFT).Methods Children with cerebral palsy(56 cases)were divided into the therapy group and the control group.They all received rehabilitation training and medication.The therapy group were treated with CVFT based upon routine treatmenL Results The effective rate in the thempy group was 96.5% and was 77.8% in the control group.There were statistical difference between the two groups(P＜0.05).Conclusions CVFY can improve the cerebral circulation,advance the blood-supply and oxygen-supply of injured cerebral tissue,alleviate the putrescence of cerebral tissue,accelerate the functional recovery of limbs of children with cerebral palsy,shorten the course of disease and improve the quality of children's life.

Objective To investigate association of the DTNBP1 gene polymorphisms with paranoid schizophrenia in Chinese Han populations by a two-stage study.Methods In the discovery stage, 11 SNPs in DTNBP1 were tested in 532 patients with paranoid schizophrenia and 488 controls by Sanger sequencing.In the validation sample (1 111 cases and 1 435 controls), Taqman genotyping method was used to genotype SNP rs4715986.Results In the discovery stage, SNP rs4715986 showed disease association (χ2=11.02, P<0.01) with paranoid schizophrenia for analysis of 532 patients and 488 controls;such an association survived a correction with 10 000 permutations (corrected P<0.05).In the validation sample (1 111 cases and 1 435 controls), we confirmed the genotypic association (χ2=9.292, P=0.01) of rs4715986 with paranoid schizophrenia.Conclusions The present results suggest that the DTNBP1 gene may be mainly involved in the development of paranoid schizophrenia in the Chinese Han population.

Objective To analyze the incidence of hospitalized children with Henoch-Sch(o)nle in purpura (HSP) and Henoch-Sch(o)nlein purpura nephritis (HSPN) from 2009 to 2012,and to characterize the epidemiology of HSP and HSPN in Jiangxi province.Methods Inpatients of Jiangxi Children's Hospital with the diagnosis of HSP or HSPN were recruited during 2009 to 2012.The basic messages in the home page of medical records,such as the admission year,sex,age,area coming from were collected.Chi-square test was used for statistical analysis.Results A total of 2516 HSP pediatric patients were included in this study.Of whom,412 cases were diagnosed in 2009,568 cases in 2010,750 cases in 2011,786 cases in 2012.Among them,renal damage as the presenting symptom in 110 cases in 2009,148 cases in 2010,198 cases in 2011,and 196 cases in 2012.The average incidence of HSPN was 25.91％ (652/2516).The morbidity of HSPN were similar in different admission years (x2=0.62,P＞0.05).In HSP patients,the ratio between male and female was 1.59∶1; the peak age was 4 to 9 year-old (65.50％,1648/2516).The morbidity of HSPN was similar in both girls and boy patients group (x2=0.14,P＞0.05).The morbidity of HSPN was 18.76％ (163/869) in patients younger than 6 years old,which was lower than 26.85％(359/1337) in patients between age 6 to 11 years old,and the morbidity of HSPN was 41.94％ (130/310) in patients older than 11years old,the difference was significant (x2=65.24,P＜0.01).The morbidity of HSP in the month of year was different,the peak time was between October and December,which as 40.74％(1025/2516).The morbidity of HSPN was 30.23％(208/688) during January to March,higher than in other period of the year (x2=9.87,P＜0.05).In the last four years,there were 824(32.75％) hospitalized patients of HSP in Nanchang district,1692 cases (67.25％) in other areas in Jiangxi province.The morbidity of HSPN in Nanchang district was 17.35％ (143/824),compared with the average level 25.91％(652/2516),the difference was significant (x2=25.08,P＜0.01).Conclusion The number of children diagnosed with HSP is progressively increased from 2009 to 2012 in Jiangxi province.The peak period for HSP is between October and December,and the peak age is 4 to 9 year-old.The incidence of HSPN between January to March group is higher than in other periodof the year.The morbidity of HSPN is increased with age.

To evaluate the effect of components in Guanxin Ⅱ prescription on the pharmacokinetic profiles of paeoniflorin and ferulic acid. METHODS: Drug concentrations of rat plasmas after intravenous injection of paronia pall (PPE) or ferulic acid (FA) extract solution, as well as oral administration of PPE and FA solution, and different kinds of decoctions based on Guanxin Ⅱ prescription were determined by an HPLC system. NONMEM (nonlinear mixed-effect modeling) method was used to analyze the population pharmacokinetics of PF and FA. RESULTS: A two-compartment model with first order degradation in absorption phase, and an ordinary two-compartment model were adequately describe PF and FA pharmacokinetic profiles, respectively. The mean of PF population parameters, CL1, V1, CL2, V2, Ka0, and Ka1, were 0.509 L/h, 0.104 L, 0.113 L/h, 0.123 L, 0.135 /h, and 0.0135 /h, respectively, while the typical values of CL1, V1, CL2, V2, Ka1, and F in FA model were 0.295 L/h, 0.025 L, 0.0331 L/h, 0.0518 L, 0.110 /h, and 0.40, respectively. Inter-individual variabilities were estimated and dose formulation (DF) was identified as a significant covariate in the model. CONCLUSION: The results indicate that the pharmacokinetic behaviors of index components in Guanxin Ⅱ prescription can be influenced by different dose formulations administrated in rats.

Objective To explore the value of brainstem auditory evoked potentials (BAEP) in the evaluation of spastic cerebral palsy (CP). Methods Forty five cases of CP children were recruited and divided, according to the diagnosis standards, into three groups: diplegia, hemiplegia and tetraplegia groups. Twenty three healthy children served as control. BAEP was recorded from all the subjects and comparisons were done among the various groups. Results The abnormality rate of BAEP in the hemiplegia and tetraplegia groups was significantly higher than that in the diplegia group ( P

OBJECTIVE To investigate the infection episode and related risk factors in continuous hemodialysis patients. METHODS The relationship among infection and etiologies of infection,nutritional status,pathogens and causes of chronic renal failure(CRF) were retrospectively analyzed in 180 continuous hemodialysis patients. RESULTS Totally 113 times infections were observed among the 86 inpatients under continuous hemodialysis.The main infectious site in hemodialysis patients was lungs.Thirty eight times were positive in 50 times of etiologic detection,Gram-negative germ was the most common(60.3%).Hemoglobin and serum albumin decreased obviously in infectious patients.Diabetes and systemic lupus erythematosus patients were more susceptible to infection.The hepatitis virus infections rate in hemodialysis patients was relatively high. CONCLUSIONS There is higher infections rate in continuous hemodialysis patients.Diabetes and systemic lupus erythematosus patients are more susceptible to infection.Anemia,lower serum albumin,old age and bad compliance are the susceptible factors.

Objective To observe the effect of heat shock protein 70 (HSP70) expression induced by Herba Hedyotis Diffusae (HHD) on the apoptosis of H22 hepatoma cells.Methlds Mice were immunized with H22 hepatoma cells from in-vivo ascites of the mice pretreated by HHD and Radix Codonopsis (RC).Mice were divided into five groups after being blocked with HSP70 monoclonal antibody:non-HHD blocking group,HHD blocking group,non-RC blocking group,RC blocking group and the blank control group,10 mice in each groups.Then the mice were attacked with cultured H22 hepatoma cells to induce transplanted tumor.The apoptosis in the transplanted tumor was detected by a terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL) method.Results Large amount of brown particles can be observed in the cell nucleus of transplanted tumor mice from HHD groups.Compared with RC groups,number of apoptotic cells and the staining intensity were increased in HHD groups.The apoptosis in HHD groups and RC groups differed from that in the blank control group,and was obvious in HHD groups.The apoptosis exerted a increasing tend in non-HHD blocking group,but the difference was insignificant between non-HHD blocking group and HHD blocking group,and between non-RC blocking group and RC blocking group.Conclusion HHD can promote the apoptosis of H22 hepatoma cells in transplated tumor through inducing the expression of HSP70 to some extent,and the related mechanism of inducing apoptosis needs further research.
