RESUMO
Objective@#To compare the ablation efficacy and therapy response with 1.1 GBq and 3.7 GBq 131I in postoperative patients with low- and intermediate-risk differentiated thyroid carcinoma(DTC).@*Methods@#A total of 190 patients (43 males, 147 females, age: (45.8±11.1)years) were enrolled from July 2016 to July 2017. Among them, 96 patients received 1.1 GBq 131I and 94 were given 3.7 GBq 131I. Diagnostic whole-body scan was performed 6 months after 131I ablation for treatment response evaluation, and the successful rate of 131I ablation was calculated. χ2 test or Fisher′s exact test was used for data analysis. The cut-off value of 99Tcm-pertechnetate uptake for predicting the successful rate of remnant thyroid ablation in 1.1 GBq group was determined by receiver operating characteristic (ROC) curve analysis.@*Results@#The successful ablation rates in 1.1 GBq and 3.7 GBq groups were 79.2%(76/96) and 81.9%(77/94), respectively (χ2=0.229, P>0.05). There was no significant difference in the therapy response between the two groups (χ2=1.371, P>0.05). The successful ablation rate in 3.7 GBq group was higher than that in 1.1 GBq group for patients with stage Ⅲ (5/6 vs 1/7, P=0.029). Moreover, for patients with 5 μg/L<preablative-stimulated thyroglobulin (ps-Tg)≤10 μg/L, the ablation rate in 1.1 GBq group was lower than that in 3.7 GBq group (3/11 vs 10/13, P=0.038). ROC curve analysis showed the cut-off value of 99Tcm-pertechnetate uptake for prediction of the successful ablation rate in 1.1 GBq group was 0.061 5.@*Conclusion@#The low- and intermediate-risk DTC patients with stage Ⅲ disease, 5 μg/L<ps-Tg≤10 μg/L or higher 99Tcm-pertechnetate uptake of remnant thyroid should be given 3.7 GBq other than 1.1 GBq 131I to obtain a better ablation efficacy.

Conclusion The low- and inter-mediate-risk DTC patients with stageⅢdisease, 5μg/L<ps-Tg≤10μg/L or higher 99 Tcm-pertechnetate up-take of remnant thyroid should be given 3.7 GBq other than 1.1 GBq 131I to obtain a better ablation efficacy.
RESUMO
Objective To analyze the stimulated thyroglobulin (sTg) level and variation tendency before and after 131I therapy in papillary thyroid carcinoma (PTC),and evaluate the predictive value of sTg for the efficacy of 131I therapy.Methods From January 2013 to September 2016,a total of 178 PTC patients (53 males,125 females;average age (44.1±11.4) years) without distant metastases who received 131I treatment in Tianjin Medical University General Hospital were reviewed.The patients were divided into two groups:group 1 (n=23) with residual thyroid detected by 131I whole body scan (WBS) and group 2 (n=155) without residual thyroid.Both thyroid stimulating hormone (TSH) and sTg were measured and defined as TSH1,sTg1 before 131I therapy,and TSH2,sTg2 after 131I therapy.Data of the two groups were compared with two-sample t test,x2 test and Mann-Whitney u test.The receiver operating characteristic (ROC) curve and diagnostic critical point (DCP) were used to evaluate the predictive value of sTg in radioiodine ablation efficacy.Results There were no significant differences in age (t=1.007),gender (x2 =1.419),tumor diameter (u=1 385),multifocal cancer (x2 =0.371),extrathyroidal extension (x2 =0.020) or lymph node metastasis (x2=0.391,all P>0.05) between group 1 and group 2.The levels of sTg1 and sTg2 of group 1 were 6.3(2.0,16.9) and 1.7(0.8,4.2) μg/L,which were higher than those of group 2 (2.7(0.6,6.4) and 0.3(0.2,1.3) μg/L;u=1 118.5,817.0,both P<0.01).△sTg and △sTg/△TSH showed no statistical differences between the two groups (u =1 359.5,1 195.0,both P>0.05).The area under ROC curve,DCP,sensitivity,specificity,positive predictive value,and negative predictive value of sTg1 were 0.686,4.435 μg/L,60.9%(14/23),67.7%(105/155),21.9% (14/64) and 92.1%(105/144),respectively.Meanwhile,the parameters of sTg2 were 0.771,0.460 μg/L,91.3% (21/23),58.1% (90/ 155),24.4%(21/86) and 97.8%(90/92),respectively.Conclusions The level of sTg could be used to predict the efficacy of 131I therapy in PTC patients.Preablative sTg1 (<4.435 μg/L) or postablative sTg2 (< 0.460 μg/L) holds high negative predictive value in identifying the efficacy of single 131I therapy.
RESUMO
Objective To investigate the toxicokinetic properties of ginkgolide B(GB) injection after single or repeat-ed administration by intravenous drip in Beagle dogs and to provide evidence for its rational use. Methods Beagle dogs were randomly divided into three groups,and received GB injection at big,medium and small doses of 80,20 and 5 mg·kg-1, re-spectively,by iv drip for 30 min per day and for 6 consecutive days per week for up to 91 days.The blood samples of Beagle dogs were drawn at different time points on the first and last day of administration,and concentrations in plasma were detected by GC-MS method.Toxicokinetic parameters were calculated by DAS pharmacokinetic software and statistically analyzed by SPSS 11.5 software. Results The elimination half-life (t1/2β) of GB at single dose of 5,20,80 mg·kg-1were(110.2±32.6),(115.4± 12.8),(98.6±26.8) min, respectively.The AUC0-twere (61.1±7.4), (348.6±90.5), (2 046.2±356.4) mg·L-1·min,re-spectively.The t1/2βof GB at mutiple doses of 5,20,80 mg·kg-1on the 91rd day were (117.9±28.0),(118.2±17.0),(120.5± 49.4) min,respectively.The AUC0-twere (67.9±14.9), (218.3±31.8), (1 986.4±426.6) mg·L-1·min, respectively.There was no significant difference in main toxicokinetic parameters including t1/2βamong the single or repeated dosage groups, but AUC0-tand Cmaxincreased proportionally with doses. Conclusion The curves of single and repeated intravenous drip of GB in-jection in beagle dogs were in line with the two atrioventricular model,with linear dynamic characteristics and there was no accu-mulation of repeated drug delivery in the body.

Objective To analyze the relevant risk factors of recurrent wheezing(≥3 attacks) in the first 3 years of life in Shanghai Pujiang.Methods A case-control study was conducted.Two hundred and sixty-two research children were chosen for clinical visits (< 3 years old) with wheezing at the Pediatric Department of Shanghai Renji Hospital (South Campus),School of Medicine,Shanghai Jiaotong University,from January to December 2014.According to the frequency of wheezing,the subjects were divided into 75 cases of recurrent wheezing group (≥ 3 attacks),110 cases of occasional wheezing group(1-2 attacks) and 77 cases of no wheezing group.Probable risk factors were inquired by using face-to-face questionnaire.The passive agglutination method was used to detect the Mycoplasma pneumoniae antibody immunoglobulin M (IgM).The indirect immunofluorescence was used to detect the respiratory pathogens.The Western blot was used to detect 20 items of serum allergen.Chi-square test was firstly used for univariate analysis,and then the multivariate stepwise Logistic regression was used to analyze the independent risk factors associated with infant recurrent wheezing.Results A total of 20 factors were found relevant to infant recurrent wheezing by univariate analysis,which included boys (OR =4.030,95% CI:1.937-8.388),personal atopy (OR =13.125,95% CI:5.951-28.946),allergic dermatitis (OR =9.833,95% CI:4.663-20.737),allergic rhinitis (OR =40.327,95% CI:5.300-306.842),like rubbing eyes or nose(OR =6.487,95% CI:3.190-13.191),food allergy (OR =6.689,95 % CI:1.860-24.051),premature birth (OR =3.795,95 % CI:1.001-14.385),low birth weight (OR =9.075,95% CI:1.106-74.450),parental atopy (OR =10.667,95% CI:4.824-23.587),parental allergic dermatitis (OR =8.072,95 % CI:2.634-24.734),parental allergic rhinitis (OR =6.524,95 % CI:2.920-14.577),parental allergic conjunctivitis (OR =1.087,95% CI:1.017-1.162),parental asthma history (OR =1.119,95% CI:1.035-1.210),colds > 6 times (OR =9.111,95% CI:3.970-20.909),history of bronchopneumonia(OR =7.554,95% CI:3.588-15.903),age at first time use of antibiotics less than 6 months (OR =2.388,95% CI:1.129-5.052),exposure to cigarette smoking (OR =1.922,95 % CI:1.004-3.681),maternal passive smoking during pregnancy (OR =2.508,95 % CI:1.298-4.848),living close to wood stove (OR =3.342,95 % CI:1.427-7.827) and positive results of inhaled allergens (OR =1.821,95 % CI:1.420-2.336).Keeping cats was the protective factor(OR =0.922,95% CI:0.864-0.984).The forward Logistic regression analysis showed that personal atopy (OR =10.278,95 % CI:2.503-42.202),like rubbing eyes or nose (OR =1 0.316,95 % CI:2.722-39.101),food allergy (OR =10.370,95% CI:1.248-86.145),parental atopy (OR =5.402,95% CI:1.340-21.778),colds > 6 times (OR =7.048,95 % CI:1.688-29.423),history of bronchopneumonia (OR =7.876,95 % CI:2.040-30.407) and maternaal passive smoking (OR =3.696,95 % CI:1.013-13.494) during pregnancy were the independent risk factors of infants recurrent wheezing.Conclusion Personal atopy,like rubbing eyes or nose,food allergy,parental atopy,colds > 6 times,history of bronchopneumonia,maternal passive smoking are the independent risk factors of recurrent wheezing in infants less than 3 years old.
RESUMO
Obgective To analyze the relevant risk factors of recurrent wheezing(≥3 attacks) in the first 3 years of life.Methods Wheezing,respiratory sounds,risk factor were used as key words to retrieve papers in Chinese literature databases including Sinomed,Wanfang and Weipu databases.The same strategy was used to retrieve English papers in English literature databases including PubMed,Cochrane library and Embase.Time range was from 31th May 2004 to 1 rd June 2014.The execution of quality evaluation of the included documents was in compliance with Newcastle-Ottawa Scale and cross-sectional study standard recommended by Agency for Healthcare Research and Quality.The evidence quality evaluation was conducted with GRADEpro and followed by the Meta analysis with RevMan 5.2.R~ults A total of 13 studies were included in this Meta-analysis.Several factors were related to recurrent wheezing episodes,including risk factors such as maternal smoking during pregnancy (OR =1.47,95% CI:1.30-1.66),asthma in parents (OR =1.94,95 % CI:1.72-2.19),family history of atopy (OR =1.94,95% CI:1.72-2.19),male (OR =1.42,95 % CI:1.19-1.69),history of eczema (OR =2.36,95 % CI:1.69-3.30),colds (> 6 times) (OR =2.02,95 % CI:1.54-2.64),history of bronchopneumonia (OR =1.85,95 % CI:1.46-2.34),exposure to cigarette smoking(OR =2.30,95% CI:1.68-3.14),daycare attendance(OR =2.27,95% CI:1.97-2.60);Education received by the mother > 12 years (OR =0.80,95% CI:0.70-0.92) was the protective factor.Conclusions The risk factors of recurrent wheezing(≥3 attacks) in the first 3 years of life are maternal smoking during pregnancy,asthma in parents,family history of atopy,male,history of eczema,colds (> 6 times),history of bronchopneumonia,exposure to cigarette smoking and daycare attendance.The protective factor is education received by the mother ≥ 12 years.The prerequisite in precaution of infants recurrent wheezing is to ensure the utmost avoidance of hazardous factors and reinforcement of protective factors.
RESUMO
Objectives To explore the changes of T helper (Th) lymphocyte and its related factors in children with syste-mic-onset juvenile idiopathic arthritis (SoJIA). Methods A total of 36 SoJIA inpatients, hospitalized from January 2012 to June 2013, were divided into active phase group and remission group. In addition, 20 healthy children were selected as normal con-trols. Th1, Th2 and Th17 cell ratios in peripheral blood mononuclear cells were detected and compared between each group by flow cytometry. Serum interferon-γ(INF-γ), interleukin-4 (IL-4), interleukin-17 (IL-17) levels were measured by enzyme-linked immunosorbent assay. Results The proportions of Th17 cells over CD3+CD8-cell were (3.30±2.15)%, (1.78±1.14)%and (1.22± 1.14)%in active phase group, remission group and control group. The difference among three groups was significant (H=14.437, P=0.001), and the active phase group had higher proportion of Th17 than the other two groups (P0.05). The serum IL-17 levels were (125.82 ± 45.87) pg/ml, (57.79±25.84)pg/ml and(50.02±18.37)pg/ml in active phase group, remission group and control group with signifi-cant difference among three groups (F=31.82, P=0.000), and the active phase group had higher level of IL-17 than the other two groups (P0.05). Conclusions Acquired cellular immunity is involved in pathogenesis of SoJIA, the increased proportion of Th1 and Th17 cell and the changes of related cytokines seem to correlate with active phage of SoJIA.
