Objective To investigate the fuction of tumor necrosis factor alpha(TNF-?),interleukin-1 beta(IL-1?) and interleukin-6(IL-6) in children with intracranial infection.Methods TNF-?,IL-1? and IL-6 levels of serum and cerebrospinal fluid(CSF) were determined in the purulent meningitis group(25 cases),tuberculous meningitis group(17 cases),viral meningitis group(30 cases)and control group(20 cases)by enzyme-linked immunosorbent assay(ELISA).Results The levels of TNF-?,IL-1? and IL-6 obviously increased in CSF compared with that in the serum (Pa

Objective To validate if the continuous passive motion instrument we developed is practical and sta- ble for animal experiment.Methods Ten New Zealand male rabbits were used to establish the animal model of full- thickness defect of articular cartilage in the facies patellaris of femur with their both knees.The rabbits were then randomly divided into groups A and B(10 in each group).The rabbits in group A were administered with CPM of both knees daily for 4 weeks,while those in group B remained normal cage activity only.At the end of the treatment,all the animals were sacrificed,and their articular cartilage was harvested for HE staining and observation.Results It was found that group A had a significantly better repair of the full-thickness defects of articular cartilage than that of the group B,as reflected by the range of motion and morphological observation of the knees(P

Objective To evaluate the relationship between combined muhigene detection and response to chemotherapy and prognosis in epithelial ovarian carcinomas(EOCS).Methods A total of 80 ovarian tissue samples taken from the surgical specimens of patients with EOCS of our hospital in the last two decades who had received chemotherapy "after surgery were paraffin-embedded.The samples were divided into 2 groups,good prognosis group(patients who survived more than 2 years,n=46)and poor prognosis group(patients who survived less than 2 years,n=34).The expression levels of ToPo-Ⅱ,Ki-67,MGMT, PCNA,p27,p53,pl6,P-gp,LRP,GST-?,bcl-2,C-myc,Fas,bax,MSH2,MRP and BCRP were investigated by the combination of tissue arrays and immunohistoehemical streptavidin-biotin peroxidase(SP) method in all samples.Data were analysed with SPSS 12.0 for windows.Results There were statistically significant differences in the positive expression levels of P-gp,BCRP,MGMT,MSH2,p27 and p16(62%, 50% and 50% in poor prognosis group vs 33%,28% and 28% respectively,P

Objective To master iodine nutritional status of people after universal salt iodization in Xining that reached the stage goal of elimination iodine deficiency disorders. Methods In the 7 counties investigated of Xining in 2009, 5 towns were randomly selected in each county, and one school was randomly selected in each town, 80 children aged 8 to 10 were randomly selected in each school, and goiter were examined, urinary iodine and salt iodine were tested. Thyroid gland goiter of children was detected by thyroid palpation, children's urinary iodine was tested by As( Ⅲ )-Ce4+ catalytic spectrophotometry, and salt iodine was tested by direct titration. Results A total of 2919 children aged 8 to 10 were examined, 31 goiter was detected, goiter rate was 1.06%(31/2919).One thousand and seventy-eight urine samples were detected, urinary iodine median was 205.3 μg/L, that lower than 20 μg/L accounted for 1.9% (20/1078), lower than 50 μg/L accounted for 4.5%(48/1078). Two thousand and seventy-nine salt samples were detected, median of salt iodine was 32.80 mg/kg, the rate of non-iodized salt was 0.87%(18/2079), the coverage rate of iodized salt was 99.13%(2061/2079), the qualified rate of iodized salt was 98.64% (2033/2061), the consumption rate of qualified iodized salt was 97.79% (2033/2079). Conclusions Prevention and control of iodine deficiency disorders has achieved remarkable results in Xining city, all indicators have reached the national standard to eliminate iodine deficiency disorders.

Objective To observe the change of stanniocalcin 1 (STC1) and calcium content in brain of coal-burning-borne fluorosis rats,and to explore the role of STC1 in brain injury of coal-burning-borne fluorosis.Methods Twenty four male SD rats were randomly divided into control,low,medium,and high fluoride groups according to body mass.Control group was fed conventional rat chow(fluorinated 1.3 mg/kg),and low,medium and high fluoride groups fed with fluorinated feed(20.0,40.0,60.0 mg/kg).All rats were given distilled water and feed ad libitum.One hundred and eighty days after modeling,STC1 protein and gene expression in the brain tissue of rats were detected using immunohistochemistry and RT-PCR and calcium content of brain tissue was detected.Results The cell positive rates of STC1 in low,medium,high fluoride groups [(48.10 + 2.11)％,(54.90 ± 1.73)％,(79.30 ± 3.71)％] were significantly higher than that of the control group[(24.70 + 3.53)％,all P ＜ 0.05],the cell positive rate of high fluoride group was significantly higher than that of the low and medium fluoride groups (all P ＜ 0.05).The STC1 mRNA expression of low,medium and high fluoride groups (0.58 ± 0.09,0.85 ± 0.17,1.75 ± 0.04) were significantly higher than that in the control group(0.37 ± 0.12,all P＜ 0.05),the STC1 mRNA expressions of high fluoride group was significantly higher than that of the low and medium fluoride groups (all P ＜ 0.05).The brain cortex calcium ion concentrations of low,medium and high fluoride groups[(138.62 + 4.19),(167.43 + 6.57),(189.45 + 3.72)nmol/L] were significantly higher than that in the control group [(101.47 + 9.46)nmol/L,all P ＜ 0.05],the brain cortex calcium ion concentrations of high fluoride group was significantly higher than that of the low and medium fluoride groups(all P ＜ 0.05),and the medium fluoride groups was higher than the low groups (P ＜ 0.05).Conclusion STC 1 may be involved in brain damage of coal-burning-borne fluorosis rats through regulating calcium balance.

OBJECTIVETo analyse the causes and the management of massive hemorrhage in hepatectomy.

METHODSWith over 1 000 ml of bleeding, 4 368 patients with hepatectomy between 1955 and 2000 were analysed retrospectively.

RESULTSAmong 4 368 patients receiving hepatectomy, 286 (6.5%) had massive hemorrhage because of damage to the major hepatic veins, portal hypertension, hepatic insufficiency, and the extensive adhesion around the tumor. Massive hemorrhage was managed by repair and transfixation of the damaged vessels; transfixation or devascularization of variceal bleeding; complete vessels ligation of the hepatic section with mattress suture; resection of the ruptured tumor after temporary occlusion of the porta hepatis; fibrinogen infusion; hot saline compression of the surface of the wound and/or daub biological glue; argon beam coagulation and packs placement.

CONCLUSIONSLight performance and nonforce dragging of liver can reduce massive hemorrhage caused by major vessel injury or tumor rupture. Normothetic occlusion of porta hepatis can reduce blood loss effectively when liver resection. In situ hepatectomy must be adopted if there is extensive adhesion around the tumor. Packs placement is still an effective measure to stop bleeding caused by defective coagulation and extensive blood oozing of wound surface.

Objective The aim of this study is to investigate the role of angiotensin-converting enzyme (ACE)gene susceptibility to systemic lupus erythematosus(SLE)by familial studies.Methods PCR-based re- striction fragment length polymorphism(RFLP)was applied to genotype single nucleotide polymorphism(SNP) G261T of the ACE gene.A total of 119 patients with SLE from 119 families were recruited.In addition,316 family members of these patients were also genotyped.A family-based association study was carried out to ex- plore the association between gene polymorphism and SLE.We studied the SNP encoding non-synonymous substitution in the ACE gene with respect to genetic susceptibility to SLE.Results Among 119 SLE patients. the frequency of ACEG261TG,T alleles was 44.8%.55.2% respectively,the frequency of ACEG261T GG,GT and TT genotypes was 13.9%,62.0%,24.1% respectively,Univariate(single-marker)family-based association test(FBAT)demonstrated that variant alleles at the SNP,rs4303,exon 5 of ACE gene were significantly asso- ciated with genetic susceptibility to SLE in Additive Model(Z=2.877,P=0.004),Dominant Model(Z=2.557, P=0.011).Recessive Model(Z=2.202,P=0.028).Transmission-disequilibrium test(TDT)and sib transmission -disequilibrium test(STDT)showed an excess of the allele of T from heterozygous parents to affected offspring or higher frequency of the allele of T in the patients than their normal siblings(X~2=11.66,P=0.001).Conclu- sion Our findings suggest that the ACE gene may he the susceptible gene to SLE in Chinese population,and the individuals carrying ACE-261T allele is significantly associated with susceptibility to SLE.
