Journal of Applied Clinical Pediatrics 1992;0(06):-
Objective To evaluate the incidence and degree of organic impairment after neonatal asphyxia,analyze the high risk factors of this and find a new approach to lower the mortality of asphyxia.Methods Two hundred and twenty-two newborns with asphyxia were studied. They were divided into mild asphyxia group and severe asphyxia group, and the function of main organs were classified as mild and severe, too. Chi-square tests were conducted for statistical analysis.Results The incidences of organic impairment and multi-organ impairment with asphyxia were 90.1 % and 71.6 % respectively. The frequency of organ dysfunction in severe asphyxia was significantly higher than that of mild group(P

Purpose To eva1uate the effects of Annexin A3 on pro1iferation and apoptosis of gastric cancer ce11s. Methods The re-combinant p1asmid pYr-ads-4-Annexin A3 was constructed and ana1yzed by restriction ana1ysis and sequencing and was transfected into MGC803 ce11s. The stab1e transfectants were obtained after screening with G418. Western b1ot ana1ysis was used to examine the expres-sion of Annexin A3 before and after transfection. CCK8 assay,c1one assay and f1ow cytometry were used to study the effects of Annexin A3 on pro1iferation and apoptosis of MGC803 ce11s. Results The recombinant p1asmid pYr-ads-4-Annexin A3 was successfu11y con-structed. Western b1otting resu1ts indicated that the Annexin A3 expression was significant1y higher in ce11s transfected with pYr-ads-4-Annexin A3 compared with ce11s transfected with empty vectors and un-transfected ce11s( P<0. 05 ). CCK8 assay resu1ts showed the number of ce11s transfected with pYr-ads-4-Annexin A3 was significant1y higher than those transfected with empty vectors and un-trans-fected ce11s(P<0. 05). Moreover,the number of c1one in ce11s transfected with pYr-ads-4-Annexin A3 was significant1y higher than the other two groups(P<0. 05). Important1y,high Annexin A3 expression inhibited to apoptosis of MGC803 ce11s(P<0. 05). Con-clusion Annexin A3 expression p1ay important ro1es in tumorigenesis of gastric cancer. Annexin A3 cou1d promote the pro1iferation and inhibited apoptosis of gastric cancer ce11s and it might be a potentia1 target for gastric cancer treatment.

Objective To observe the effects of Huangqi Sanxian Decoction,an invigorating kidney and activating blood Chinese medicine,on ultramicrostructure of brain immunocyte of ovariectomized rats.Methods Fifty female rats were randomized into five groups:sham operated group,model group,high-dosage treatment group,low-dosage treatment group and Naofukang control group.The rats models in these groups were established by excising two ovary from dorsal incision,and the same size of fat was excised in the sham operated group.The treatment groups were administrated Huangqi Sanxian Decoction by gastric gavage,the period of treatment for 4 weeks.The status of hippocampal artrocytes,the level of interleukin-6 and serum estradiol were observed after treatment for 4 weeks.Results Ovariectomy can induce hyperplasia of hippocampal artrocytes in the central nervous system,while Huangqi Sanxian Decoction can reduce the artrocyte number,increase the estradiol level and decrease the interleukin-6 level in a dose-dependent manner.Naofukang control group showed no influence on estradiol level.Conclusion Huangqi Sanxian Decoction can inhibit the artrocyte hyperplasia and inflammatory responses in the hippocampas of central nervous system.It exerts protective effects by increasing the estradiol level probably.
6.Reactivation of human herpesvirus 8 by hepatocyte growth factor/scatter factor similar to that produced by HIV-1-infected T cells via ORF50 promoter of HHV-8
Chinese Journal of Infectious Diseases 2001;0(03):-
Objective To investigate a potential role for ORF50 promoter of human herpesvirus 8(HHV 8)in reactivation of HHV 8 in primary effusion lymphoma(PEL)BC 3 cells by HIV 1 related inflammatory cytokine,hepatocyte growth factor/scatter factor(HGF/SF). Methods The persistent stimulation of BC 3 was performed by recombinant HGF/SF and treated BC 3 cells were collected at the 3 rd and 7 th day after persistent stimulation respectively. Northern blot, quantitative PCR(real time PCR), and electron microscopy(EM)were carried out to detect the expression of mRNA of minor capsid protein ORF26 and the presence of viral particles of HHV 8 from treated BC 3 cells. Co transfection of BC 3 and human umbilical veil endothelial cells (HUVECs) with HHV 8 ORF50 promoter driven luciferase construct built previously by us and recombinant expression plasmid named pEV containing HIV 1 Tat coding gene was performed and stimulation of co transfected cells with recombinant HGF/SF and/or HIV 1 recombinant gp120 was conducted at 24 hours after transfection to induce luciferase gene expression. Then relative luciferase activity unit(RLU) was calculated at 24 hours after stimulation. In the meantime, stimulation of co transfected cells with 12 O tetradecanoylphorbol 13 acetate(TPA) was performed to be used as positive control. Results It was found that HGF/SF induced an 4.1 folds increase in mRNA expression of ORF26 when it was added individually to BC 3 cells at the 7 th day after persistent stimulation. Viral particles of HHV 8 were readily identified in BC 3 cells stimulated with HGF/SF at the 7 th day with EM analysis. Recombinant HGF/SF could upregulate promoter activity of HHV 8 ORF50 promoter in BC 3 and HUVECs cells and however, HIV 1 Tat and gp120 failed to act synergistically with HGF/SF to enhance ORF50 promoter activity in HUVECs. Conclusions The results show that HIV 1 related inflammatory cytokine HGF/SF is responsible for the induction of HHV 8 lytic cycle replication and the induction may be, at least partly mediated by ORF50 promoter of HHV 8.

Objective To evaluate the effects of inhaled aerosolized different doses of lidocaine on lung injury in patients undergoing cardiac valve replacement under cardiopulmonary bypass (CPB).Methods Thirty ASA physical status Ⅱ or Ⅲ patients of both sexes,aged 18-58 yr,weighing 35-70 kg,undergoing elective cardiac valve replacement with CPB,were randomly divided into 3 groups (n =10 each) using a random number table:control group (group C),lidocaine 100 mg group (group L1) and lidocaine 200 mg group (group L2).Anesthesia was induced with iv injection of midazolam,etomidate,fentanyl and vecuronium.The patients were endotracheally intubated and mechanically ventilated.The aemsolized normal saline 10 ml,2% lidocaine 5 ml + saline 5 ml and 2% lidocaine 10 ml were inhaled in C,L1 and L2 groups,respectively,starting from 10 min after induction.At 10 min after induction (T0),1 and 10 min after opening of vena cava (T1,2),and the end of CPB (T3),blood samples were collected from the left radial artery (LRA) and right atrium (RA) for determination of plasma interleukin8 (IL-8),tumor necrosis factor-α (TNF-α) and malondialdehyde (MDA) concentrations (using ELISA) and the expression of CD11 b on polymorphonuclear leukocytes (by flow cytometry).Blood samples were collected from the left radial artery at T0,immediately after beginning of CPB,at T3 and at 2 and 6 h after termination of CPB for blood gas analysis.The oxygenation index (OI),respiratory index (RI) and dynamic lung compliance (Cdyn) were calculated.Results Compared with group C,the ratio between IL-8 concentration in LRA and in RA (concentration of IL-8LRA/RA) was significantly decreased at T2,3,the concentration of MDALRA/RA was decreased at T3 (P < 0.05),no significant change was found in the expression of CD11bLRA/RA at each time point (P > 0.05),and RI was decreased at T3 in L1 and L2 groups (P < 0.05).There were no significant differences in the concentration of IL-8LRA/RA,TNF-αLRA/RA and MDALRA/RA,expression of CD11bLR A/RA,RI,OI and Cdyn at each time point between group L2 and group L1 (P > 0.05).Conclusion Aerosolized lidocaine inhalation can attenuate lung injury and improve lung function in patients undergoing cardiac valve replacement under CPB by reducing inflammatory responses and lipid peroxidation in lung tissues.
