Objective To explore the lesion distribution pattern of poststroke pathological laughing or crying (PSPLC) by using MRI,and to discuss its pathogenesis. Methods All 24 cases selected from stroke patients who were treated in the department of neurology from May 2012 to December 2015 and had complete follow?up information after their discharge through 6 months were screened for pathological laughing and crying( PLC) . MRI characteristics of cases were analyzed retrospectively to identify lesion distribution. 28 cases with acute isolated pontine infarction who did not demonstrate PLC were enrolled as a comparison group. Lesion pattern difference between 14 cases of the pontine infarction with PLC and 28 cases of acute i?solated pontine infarction without PLC was compared. Results In these 24 cases,the highest occurrence rate of PLC was 41.67% in the second month. 15 cases had forced crying (62.5%),3 cases had forced laughing (12.5%),6 cases had pathological laughing or crying (25%). MRI studies showed lesion location in the left side were 3 cases,in the right side were 1 case,in the bilateral brain were 20 cases,in the basal ganglia were 9 cases,in the thalamus were 8 cases,in the corona radiata were 6 cases,in the semioval center were 5 cases, in the cerebral cortex were 4 cases,in the cerebellum were 4 cases and in the brain stem were 14 cases. In the cases of PLC with brain stem lesion,only 1 case was isolated pontine infarction,the other patients all combined with lesions of other parts. Compared with the pontine infarction with PLC,the isolated pontine in?farction without PLC was more likely to suffer with unilateral brain lesions(71%vs 50%),but there was no significant difference (χ2=0.844, P=0.358) . Conclusion PSFLC is not a rare complication after stroke, which is associated with multiple site of brain involvement especially pontine infarction.

Objective The investigate the clinical significance of serum anti-thyroid peroxidase antibody(TPOAb)monitoring in therapeutic effect judgment and prognosis evaluation during 131I treatment in patients with Graves disease.Methods A total of 112 patients with Graves disease(hyperthyroidism group)and 50 healthy controls(healthy control group)were enrolled in the investigation.Serum concentration of TPOAb was measured with chemiluminescent immunoassay(CLIA)in healthy control group and hyperthyroidism group(at time points of 0,3,6,12 and 24 months after 131I treatment,i.e.T0,T3,T6,T12 and T24).Variance analysis and t test were adopted.Results The mean level of TPOAb was significantly higher in patients with Graves' disease before 131I treatment than that in healthy controls(P＜0.01).In hypenthyroidism group,serum concentration of TPOAb was evidently higher at T3[(108.94±70.15)IU/mL]than T0[(81.95±47.64)IU/mL](P＜0.01);TPOAb level began to decline at T6[(42.78±28.68)IU/mL],but still higher than that of healthy control group;while where was no statistical difference in TPOAb level between hyperthyroidism group at T24[(7.89±4.01)IU/mL]and healthy control group(F＞0.05).Conclusion Serum level of TPOAb before treatment may be used as an auxiliary indicator of 131I dosage.Posttreatment TPOAb level monitoring contributes to therapeutic effect evaluation,follow-up visit and immunorcaction state understanding.

Some non treatment variables that affect the outcome of a disease are often called covariates. These covariables should be considered in the design and analysis of clinical trials to obtain unbias conclusion. To ensure that any observed treatment effect is not influenced by an imbalances in baseline characteristics, both preadjustment and postadjustment are provided in the design stage and analysis stage of the trials respectively. They can improve the credibility of the trial results and increase the statistical efficiency. Based on a few papers published about adjustment for covariates and some documentations of the International Conference on Harmonization (ICH), we review the concepts, methods and procedures for adjustment of treatment effects for the influence of covariates. The statistical issues on the application of adjustment are especially discussed in great depth.
