Objective The study is mainly on the effect and outcome of 131 I treatment for children and adolescents with differentiated thyroid cancer .Methods We compared the difference between rhTSH -aided ra-dioiodine treatment and L -thyroxin withdrawal .Our study collected 87 patients in a retrospective study .In order to analysis the effect,we divided into two groups.The experimental group has 46 patients,and control check has 41 patients.We compared the basic characteristics and mortality in different groups by χ2 -test,t-test and F-test based on data type .Results The thyroid stimulating hormone concentrations of experimental group patients have significant differences in the first ,the third and the sixth day after the injected of rhTSH ,the third day is the highest.The TSH concentration has significant difference between the two groups before 131I treatment(t=2.362, P=0.023).For the Tg(thyrobolulin)negative patients,Tg concentration in control check is higher than the third day after injected of rhTSH in the experiment group (1.5 ±1.2 vs.0.7 ±1.4,P=0.034).Whole body image has been done by scintigraphic after 3~8 months of 131I treatment.Thirty four(84%)patients have no radioiodine up-take in experiment group,and 40(87%)patients have no radioiodine uptake in control check ,there is no differ-ence between the two groups (χ2 =0.277,P=0.599).There is no difference between the two groups on the rea-son for retreatment(P=0.875).Conclusion The outcome of rhTSH -aided radioiodine treatment is similar to L-thyroxin withdrawal in short -term recurrences ,and rhTSH-aided radioiodine treatment with 131 I therapy for children and adolescents with DTC is a better method .

Objective To observe the effects of estrogen on the behavior and the norepinephrine level in the habenular nucleus of depressive rats,and explore the mechanism of estrogen involved in the process of antidepression.Methods Thirty rats were chosen from forty male Wistar rats,which had the similar scores in open field test.The depression models of rats were established by chronic mild stress.Open field test and forced swimming test were performed to detect the behavioral changes between rats with ovary excision(OVX) and with estradiol-treated ovary excision(OV/ER).High performance liquid chromatography(HPLC) was used to observe the changes of norepinephrine level in habenular nucleus.Results After 21-day chronic mild stress,the open field test showed that the vertical motion and cross motion in OV/ER group were increased(P

Objective To evaluate the effect of different education models on the self care ability of peripherally inserted central catheters (PICC) placement patients.Methods The randomized controlled trial (RCT),controlled clinical trail (CCT),self-controlled trial and cohort study on self care ability of patients with PICC placement were collected using databases by manual and Internet searching.Data were analyzed with Revman5.0 software,data which could not be gathered were expressed by descriptive analysis.Results Eight articles were included in the study.The results of Meta-analysis revealed that different education models could significantly improve the self care ability of PICC patients in the intervention (experimental) group.Conclusions Different education models had significant meaning on the self care ability of PICC placement patients.

ICH GCP requires that all information of clinical trial should be recorded, processed, and stored in a way that allows the accurate reporting, interpretation and verification. A trial master file (TMF) contains all paper or electronic records/documentations related to a clinical trial. As a tool of the retrospective analysis, the TMF profile should be able to reproduce the full procedure of the trial completely. As a part of TMF profiles, both the accuracy and completeness of clinical data management documentation are important in data integrity. It is helpful to learn the workflow of clinical data management in different stage of a clinical trial, to understand which documents are essential, and why the documentation of clinical data management is important for data integrity. This paper elaborates how to perform the good documentation practice of clinical data management, and suggests that both the precise and efficient document management and regular quality control may ensure the high quality of clinical data documentation management on the basis of an intensive awareness of the overall process of clinical data management.

Background Microvessels are composed of two interacting cell types: endothelial cells and pericytes. Over the past decades, studies of corneal angiogenesis have concentrated mainly on endothelial cells, while interest in pericytes has lagged behind. Objective The present study aimed to investigate the recruitment of vascular endothelial cells and pericytes in rat corneas after alkali burn. Methods Corneal alkali burn models were established in the right eyes of 36 adult SPF SD rats by putting 4 mm medicators containing a 1% 1 mol/L NaOH solution at the central corneas for 30 seconds, and 3 matched normal rats were used as controls. Corneas were excised 1,2,3,5,7 and 10 days after surgery. Frozen sections that parallel with the corneoscleral limbus were constructed. Double immunofluorescence staining was used to observe the dynamic expression of CD31 and α-smooth muscle actin (α-SMA) in corneal tissue for the evaluation of the number of endothelial cells and pericytes. The pericyte coverage index (PCI) was calculated to quantify the recruitment of pericytes to neovascular sites. The use of experimental animals followed the Statement of Association for Research in Vision and Ophthalmology. Results CD31 was expressed in the superficial stromal layer of the cornea on the 1 st day, showing the presence of red fluoresence. The positive cell number for CD31 was gradually increased with the passage of time and proceeded into the deep stromal layer from days 2 through 5 but decreased after that. However,α-SMA was positively expressed on the 2nd day in the cornea after alkali burn with the presence of green fluorescence. The positive cell number for α-SMA was less than those of CD31 throughout the experimental period. The PCI was 0, 16.07%, 11.95%, 43.84%, 73.97% and 86. 21% , respectively, 1,2,3,5,7 and 10 days after surgery. Conclusion Pericytes recruitment to corneal new vessels may play a key role in the stabilization and maturation of angiogeneis.

Objective To investigate the correlation between executive function(EF) and characteristic of symptom in children with Tourette′s syndrome(TS).Methods EF were measured with Wisconsin Card Sorting Test(WCST) in 53 patients with TS,and symptom characteristics were evaluated with Achenbach Child Behavior Checklist(CBCL) and Yale Global Tic Severity Scale(YGTSS).Results Compared with healthy control,TS had poor executive performances significantly in WCST(all P

Objective To investigate the different distribution of regulatory T cells (Tregs) and CD8+T cells in the local immune microenvironment of mucosal malignant melanoma and cutaneous malignant melanoma, and analyze the relationship between the two indicators and the prognosis of patients. Methods Immunohistochemistry staining was used to assess the ex?pression of Foxp3+Tregs and CD8+T cells in tumor microenvironment of 58 patients with malignant melanoma. The correlation between two factors, clinicopathological characteristics, and prognosis were analyzed. Results There is no correlation be?tween the expression of Foxp3 and CD8. The number of Foxp3+Tregs was significantly higher in mucosa malignant melanoma than that in cutaneous malignant melanoma (t=2.648, P=0.011). The proportion of Foxp3highTregs was significantly higher in pa?tients with tumor diameter≥3 cm, lymph node metastasis and distant metastasis than that in patients with tumor diameter<3 cm, no lymph node metastasis and no distant metastasis (P<0.05). In addition, in patients with ulceration that proportion was significantly higher in CD8high group than that in patients without ulceration (33.3%vs 5.9%, P<0.05). The median progres?sion-free surial (PFS) was 12 months in Foxp3high group, which was significantly longer than that of Foxp3low group (31 months, P<0.05). The median PFS was significantly higher in CD8high group (25 months) than that of CD8low group (12 months, P<0.05). Subgroup analysis showed that the median PFS was 7 months in Foxp3high CD8low group, which was significantly lower than that of Foxp3highCD8high group (25 months) and Foxp3lowCD8low group (18 months, P=0.003). Univariate analysis showed that median PFS was different in patients with different tumor location, different number of Foxp3+Treg, different number of CD8+T cells, and distant metastases. Conclusion The number of Tregs is closely associated with metastasis in patients with malig?nant melanoma. Compared with cutaneous malignant melanoma, our results indicate that the poor prognosis of mucosal malig?nant melanoma may be associated with the infiltration of more Tregs.
