Objective To investigate the effects of propofol and sevoflurane on oxidative stess response induced by short period pure oxygen inhalation during general anesthesia.Methods Sixty ASA Ⅰ or Ⅱ patients aged 20-60 yr weighing 50-85 kg undergoing elective abdominal surgery under general anesthesia were randomly divided into 2 groups (n=30 each):group propofol (group P) and group sevoflurane (group S).Each group was further divided into 2 subgroups inhaling 40% O2 (P0.4,S0.4) and 100%O2(P1.0,S1.0) respectively during operation.Anesthesia was induced with propofol 1-2 mg/kg,midazolan 0.02 mg/kg and sufentanil 0.1-0.2 mg/kg.Tracheal intobation was facilitated with rocuronium 0.6-0.8 mg/kg.The patients were mechanically ventilated(VT 8 ml/kg,RR 12 bpm).PET CO2 was maintained at 35-40 mmHg.Anesthesia was maintained with in both groups.BIS was maintained at 40-60.Arterial blood samples were collected immediately before induction of anesthesia (baseline),at 2,4,6h after tracheal intubation(T1-3) and 24h after operation(T4) for determination of PaO2,serum 8-iso-PGF2α and MDA concentrations and SOD activity.PaO2/FiO2 was calculated.Results In subgroup S1.0 the serum 8-iso-PGF2α and MDA concentrations were significantly increased while serum SOD activity was significanfly decreased at T1-3 as compared with the baseline.Serum 8-iso-PGF2α and MDA concentrations were significantly higher while serum SOD activity and PaO2/FiO2 were significantly lower at T1-3 in subgroup S1.0 than in stress response induced by≤6h pure O2 inhalation but inhalation of 1.5%-3.0% sevoflurane can not.

Objective To investigate the toxicities and inhibitory effects of three kinds of kegin-type novel heteropoly compounds which were synthesised by molecular assembly interactions on influnenza A virus(H1N1) in vitro.Methods The toxicities and anti-influnenza virus activities were tested by methods of CPE-MTT and chick embryos culture.Results TC_(50) in MDCK cells and LD_(50) in chick embryos of three kinds of kegin-type novel heteropoly compounds were higher than those of amantadine.TI in MDCK cells and chick embryos were both higher than that of amantadine. Conclusion The three kinds of kegin-type novel heteropoly compounds have lower toxicities and higher anti-virus effects on influnenza A virus(H1N1) than amantadine.Through chemic modifications,the toxicity of amantadine can be decreased and the activity of amantadine can be increased.

Objective To investigate the screening state and cause of neonatal congenital hypothyroidism(CH) in Henan province.Me-thods Three hundred and thirty-eight thousands no-choice newborns in the 156 hospitals in Henan province from Jan.1998 to Dec.2004 were received screening.The heel peripheral blood samples were taken and the levels of thyroid-stimulating hormone(TSH) were mea-sured by time-resolved fluoroimmunoassay.Positive newborns were recalled and draw out 2 mL venous blood.The levels of TSH,triiodothyronine(T3) and thyroxine(T4) in serum were detected by direct chemiluminescence.The abnormal criterion was that the level of T3,T4 was under the normal range and the level of TSH was above the normal range.Meanwhile their growth and development,intelligence quotient,related medical examination and family histories were investigated in order to find etiological factors and high risk factors.Results The average coverage rate was 5.93% of neonatal screening for CH in Henan province.One hundrend and nine infants were diagnosed CH.The attack rate was about 0.032%.The site and growth of thyroideas of 109 cases with CH were all normal.There were higher morbidity for pregnant women with unhealthy condition or the families with hypertension,diabetes,deformity or dysnoesia.Conclusions Etiology of newborns with CH in Henan province may be not relate with congenital absence and dystopia of thyroidea,but relate with dyssynthesis and receptor deficiency of hormone.And scientific reference is offered for the further study.

Objective To discuss human papilloma virus(HPV)prevalence and HPV genotypes distribution and the infection factors,to provide scientific guidance for the prevention and treatment of cervical cancer.Methods From March to November in 2009,605 women received cervical HPV testing in the Tumor Hospital of Harbin Medical University,to obtain specimens of cervical cytology,rapid flow-through hybridization technique (namely Hybribio flow-through hybridization)was used to detect HPV genotypes simultaneously.Single-factor and multivariate factors non-conditional Logistic regression analytic method was used to discuss the relationship between HPV infection of females and age,marital condition,level of education,level of income,occupation,initial age for sex,contraception,number of pregnancies,delivery approach and smoking.Results HPV infection rate was 21.49%(130/605),the positive rate of HPV infection in high-risk subtypes was 15.70%(95/605),the most common type was 5.29%(32/605)in the samples.Single factor non-conditional logistic regression model analysis showed that initial age for sex was the risk factor(X2=4.4618,P<0.05),HPV prevalence increased with a lower initial age for.sex reduced.But there was no significant difference in age,marital condition,education,income,occupation,contraception,number of pregnancy,delivery approach and smoking teams(X2=0.0525,1.8510,1.0348,0.2592,1.1176,1.5664,2.8835,1.4597,2.6161,all P>0.05).The analysis of multivariate factors nonconditional Logistic regression showed that the age of initially having sex,marital status and number of pregnancies were the risk factors(X2=21.6637,8.0574,15.7573,all P<0.05).Conclusions The risk factors for HPV infection are mainly about having sex too young,marital status and number of pregnancies,attention should be paid to screening for HPV.

Objective To investigate the relationship between urinary iodine level and thyroid disease.Methods The study used a case-control design.One hundred and nine patients with thyroid disease from the Affiliated Hospital of Shanxi Institute for Endemic Disease Control were selected as case group from 2011 to 2012,and these patients were divided into three groups:Graves's disease (GD) group (n =48),chronic lymphocytic thyroiditis (HT) group(n =34) and thyroid nodules group(n =27).Sixty-two healthy people from the same region were selected as a control group.Urinary iodine was determined using arsenic cerium catalytic spectrophotometry,thyroid autoantibody (TRAb) and thyroid peroxidase antibody (TPOAb) was detected using electrochemiluminescence,while iodine absorption rate was measured using thyroid function analyzer,and thyroid volume was measured using type-B ultrasonic method.The relationship between urinary iodine level and patients with thyroid disease was compared with that of control group.Results Urinary iodine levels of patients with GD,HT,thyroid nodules and control groups were 313.95,375.20,220.20 and 196.50 μg/L,respectively.Urinary iodine levels of patients with GD and HT groups were higher than that of control group(Z =3.238,4.275,all P ＜ 0.0125).Urinary iodine level of patients with HT was higher than that of thyroid nodules(Z =3.762,P ＜ 0.0125).Iodine uptakes of GD,HT,thyroid nodules and control groups were (84.20 ± 16.90)％,(23.51 ± 6.72)％,(28.34 ± 8.02)％ and (29.31 ± 8.41)％; TRAbs of patients with GD,HT,thyroid nodules and control groups were (58.57 ± 20.31)％,(2.54± 1.00)％,(2.98 ± 0.83)％ and (3.01 ± 1.21)％; TPOAbs of patients with GD,HT,thyroid nodules and control groups were (117.03 ± 57.21)％,(251.00 ± 98.20)％,(16.81 ± 9.87)％ and (15.00 ± 7.23)％.Iodine uptake,TRAb and TPOAb of GD group were higher than those of control group(P ＜ 0.05).TPOAb of HT group was higher than that of control group(P ＜ 0.05).Urinary iodine levels of GD group and HT group were positively correlated with TPOAb(correlation coefficient were 0.462,0.478 all P ＜ 0.05).Conclusions Excessive iodine intake is found in patients with GD and HT.Determination of urinary iodine is helpful for individualized iodine supplementation.
