Objective To investigate the effects of ultrarapid opiate detoxification during general anesthesia on the plasma morphine concentration and brain ?-endorphin content in rats addicted to morphine. Methods Ninety male Wistar rats aged 12-15 weeks weighing 180-220 g were randomized into 6 groups: group I normal animal ( n = 5); group II morphine addiction ( n = 5); group III natural withdrawal ( n = 20); group IV general anesthesia ( n = 20); group V general anesthesia + naloxone ( n = 20) and group VI clonidine pretreatment ( n = 20). Morphine addiction was induced by subcutaneous injection of increasing doses of morphine sulphate for 5 days (5, 10, 20, 40 and 50 mg? kg-1 t.i.d. ? 5 days) . Morphine detoxification was started on the 6th day. General anesthesia was induced and maintained with ?-OH and midazolam i.m. supplemented with intermittent isoflurane inhalation to maintain loss of righting reflex. Spontaneous breathing was kept during general anesthesia. In group V naloxone 0.05, 0.1 and 0.2 mg was injected subcutaneously at 5, 30 and 60 min after loss of righting reflex. Successful detoxification was defined as no withdrawal symptoms after subcutaneous injection of naloxone 0.1 mg. In group VI clonidine 0.05 mg ? kg-1 was given i. v. 1 hour before induction of anesthesia. Blood samples and brain tissue were obtained before detoxification in group I (normal animal) and II (morphine addiction) while in the other 4 groups they were obtained immediately and 1,2,3 day after detoxification.Results The plasma morphine concentration was 224 ? 164 ng?ml-1 in group II (morphine addiction), significantly higher than in all the detoxification groups ( P V ) (P

Objective To assess the short-time economics of various glutamine dipeptide-enriched parenteral nutrition (PN) for patients undergoing elective surgery for gastrointestinal tumors, with an attempt to provide evidence for decision makers on clinical nutrition support.Methods A prospective cohort study was designed.From payer/disburser''s perspective, a cost-effectiveness decision-tree model was developed to assess the clinical outcomes and short-time economic effects of glutamine dipeptide-enriched PN that used in different time points (early postoperative or perioperative).Cost-effectiveness analysis, cost-utility analysis, and incremental cost-effectiveness analysis were adopted in the decision-tree model.One-way sensitivity analysis was performed to determine the robustness of the results.Results Totally 107 patients were included.There was no significant difference between the perioperative alanine(Ala) glutamine(Gln) nutrition support (group A) and early postoperative Ala-Gln nutrition support (group B) in the ratio of 5％ weight declines on the 8th day after surgery and infection-related postoperative complications (72.1％ vs.78.1％, χ2=0.509, P=0.498 and 2.32％ vs.4.69％, χ2=0.060, P=0.806).The levels of prealbumin (PA) and albumin(Alb) and the level of total lymphocyte count(TLC) also the time of recovering gastrointestinal function, length of stay nutritional discharge index(LOSNDI), and direct costs were significantly different [PA:(208.19±56.92)mg/L vs.(187.97±62.05)mg/L, t=2.283,P=0.039;Alb:(33.82±3.91)×109 vs.(31.96±4.57)×109, t=2.184, P=0.036;TLC:(1.19±0.55)×109 vs.(0.89±0.66)×109, t=2.461, P=0.015;the time of recovering gastrointestinal function(3.06±0.28)d vs.(3.39 ± 0.34)d, t=-3.675, P=0.000;LOSNDI:(16.84±2.92)d vs.(18.52 ±3.47)d, t=-2.613, P=0.011;direct costs:￥(17 029.05±317.28) vs.￥(15 610.64±292.56), t=23.764, P=0.000].When LOSNDI and quality-adjusted life years (QALYs) were estimated as indicators of effectiveness, the incremental cost-effectiveness ratios and incremental cost-utility ratios of group A were ￥844.3 and ￥70 920.5, respectively.Net monetary benefit of group B was more than that of group A.One-way sensitivity analysis showed that parameters had no significant effect on the model.Conclusion When using local per capita gross domestic product as threshold, early postoperative Ala-Gln PN was more economical than perioperative Ala-Gln PN strategy evaluation.

Objective To investigate the prevalence of thyroid disorders and positive thyroid autoantibodies,and evaluate the necessity for universal thyroid screening during the second and third trimesters of pregnancy.Methods The pregnant women during the second and third trimesters who visited Shanghai Jiaotong University Affiliated First People's Hospital between June 2006 and February 2008 were chosen for thyroid screening by determining serum free triiodothyronine,free thyroxine,thyrotropin,thyroid peroxidase antibody (TPOAb),and thyrotropin receptor antibody.A personal and family history of thyroid disease and other autoimmune diseases was investigated by questionnaire.The pregnant women were divided into high risk or low risk groups for thyroid disease based on their personal or family histories.Results A total of 2 101 pregnant women were screened,712 ( 33.89％ ) of them were identified to suffer from thyroid disorders or with positive thyroid autoantibody.The prevalence of thyroid dysfunction was increased in high risk group.While in low risk group( n =1 983 ),the prevalence of clinical hypothyroidism was 2.27％ ( n =45 ),subclinical hypothyroidism 11.60％ ( n =230 ),clinical hyperthyroidism 0.20％ ( n =4 ),subclinical hyperthyroidism 1.06％ ( n =21 ),hypothyroxinemia 6.45％ ( n =128 ),and euthyroid with positive TPOAb 10.74％ ( n =213 ) in our study.Pregnant women with positive TPOAb were susceptible to thyroid dysfunction.It was shown that 79.74％ of pregnant women with thyroid disorders were diagnosed by universal thyroid screening.Conclusions 33.89％ of pregnant women in the second and third trimesters were identified to suffer from thyroid disorders or positive thyroid autoantibody by universal thyroid screening.Increased prevalence of thyroid dysfunction was found in pregnant women with positive TPOAb.79.74％ of pregnant women with thyroid disorders might be missed if screening was made only in the high risk cases.

ObjectiveTo investigate the influence of positive serum thyroid peroxidase antibody (TPOAb) on pregnancy outcomes in biochemically euthyroid women during gestation.MethodsFrom July 2006 to December 2010,in the prenatal care unit all pregnant women,who had no medical and family history of thyroid diseases,underwent thyroid function screening.Serum TPOAb was tested among those pregnant women with euthyroidism.Pregnancy outcomes,including obstetric complications,neonate birth weight,and Apgar score,were compared between 185 TPOAb positive women and 1417 TPOAb negative women.ResultsCompared with TPOAb negative women,it was more frequent for TPOAb positive women to suffer from various obstetric complications.The prevalences of umbilical cord entanglement ( 18.9％ vs 12.9％,RR =1.47,95％ CI 1.06-2.03,P＜0.05 ),threatened premature delivery or abortion (3.8％ vs 1.0％,RR =3.83,95％ CI 1.57-9.37,P＜0.05 ),intrauterine growth retardation (5.4％ vs 0.8％,RR =6.96,95％ CI 3.00-16.17,P＜0.01 ),and neonatal pneumonia ( 4.9％ vs 1.3％,RR =3.83,95％ CI 1.75-8.40,P＜0.01 ) in the group of TPOAb positive women were higher than those in the group of TPOAb negative women.Apgar score of those newborns whose mothers had positive TPOAb was 9.27 ±1.13 at one minute and 9.44 ± 1.09 at five minutes,being lower than that of the TPOAb negative group (9.49 ±0.69 and 9.68 ±0.52,both P＜0.01 ).The rate of newborns with Apgar score at 7 or less by 5 min in group with positive TPOAb was higher than that of group with negative TPOAb ( 1.6％ vs 0.1％,RR =11.49,95 ％ CI 1.93-68.31,P＜ 0.05 ).ConclusionsThese results indicate that pregnant women with normal thyroid function but positive TPOAb may be liable to increase risk of serious pregnancy outcomes,such as threatened premature delivery or abortion,intrauterine growth retardation,and a lower Apgar score in neonatal.

ObjetiveTo investigate the obstetrical and neonatal outcomes of pregnant women with hypothyroidism or subclinical hypothyroidism.MethodsOne hundred and sixty-eight pregnant women with clinical or subclinical hypothyroidism during pregnancy,including 9 controlled hypothyroidism,29 uncontrolled hypothyroidism and 130 subclinical hypothyroidism,were enrolled in this study.The general clinical information,obstetrical complications and neonatal outcomes of these pregnant women were compared with that of 180 healthy pregnant women who delivered during the same period.ResultsCompared with control group,there were no significant differences in the levels of serum free triiodothyronine( FT3 ),free thyroxine ( FT4 ),thyrotropin-stimulating hormone (TSH) in the controlled hypothyroidism group in the third trimester [(3.68 ±1.11 ) pmol/L vs (3.19 ±0.33) pmol/L,(15.48 ±4.14) pmoL/L vs (13.95 ± 1.68) pmol/L,1.87 mU/L vs 1.76 mU/L,P ＞0.05].However,in the second and third trimester,the levels of FT3,FT4 in the uncontrolled hypothyroidism group were lower,while the levels of TSH were higher than in control group [(2.71 ±0.80) pmol/L vs (3.14 ± 0.34) pmoL/L,(10.94 ± 2.68) pmol/L vs (14.25 ±2.01) pmol/L,5.62 mU/L vs 2.28 mU/L,( 2.34 ± 0.70 ) pmol/L vs ( 3.19 ± 0.33 ) pmol/L,( 10.16 ± 1.65 ) pmol/L vs (13.95 ± 1.68) pmoL/L,7.13 mU/L vs 1.76 mU/L,t =2.754～9.15,P ＜0.01],the levels of TSH in the subclinical hypothyroidism were higher than in control group ( t =18.28,18.57,P ＜0.01 ).There was no adverse perinatal outcome of neonate happened in controlled hypothyroidism group.In contrast,the incidences of adverse perinatal outcomes and complications in the uncontrolled hypothyroidism group were higher than that in the control group ( 17.2％ vs 2.8％,37.9％ vs 5.6％,x2 =11.47,28.97,P ＜0.01 ).Compared with that of control group,the incidences of adverse obstetrical outcomes in pregnant women with subclinical hypothyroidism were increased (40.0％ vs 5.6％,x2 =52.97,P ＜ 0.01 ).ConclusionsThe rate of adverse obstetrical outcomes and complications is increased in women with clinical or subclinical hypothyroidism.But the incidence of adverse outcomes would decrease if hypothyroidism is controlled by treatment.
