Objective The analysis of correlation between the occurrence of tourette syndrome with one-child family environment. Methods The authors investigated home environment of two groups. One group included 200 patients with tourette syndrome and is the other group included healthy children of the same age in 3 different primary and secondary schools. By comparing with the home environmental factors, parenting styles and parent emotional factors between two groups. Results The instabilities of home environment included bad family relationship, separation between parents, divorce, scolding and even beating children. It showed that anxiety of the direct supervisors among the sickness group were higher than healthy control group as well. Among the ten factors of the Family Environments Scale, the significant differences showed in six factors of affection,cohesion,expressiveness, conflict, intellectual-culture orientation, active-recreational orientation, organization between the two groups. Conclusion So we concluded that ①There is a correlation between the parents relations,parenting styles and the incidence of tourette syndrome; ②An anxiety of the direct supervisor may initiate, even aggravate the incidence of tourette syndrome; ③It is important to convert the education mode and take family overall treatment in order to reduce the incidence and improve the effectiveness of tourette syndrome.

Objective To investigate the effects of crude extracted proteins from lesions of condyloma acuminata on immunophenotypes of dendritic cells.Methods Plastic-adherent mononuclear cells(MNCs)were isolated from umbilical cord blood or peripheral blood and cultured in media containing cytokines(GM-CSF,IL-4and LPS).The morphology and phenotypes of these cells were analyzed by flow cytometry and microscopy in12day's culture.Cells on the fourth day were incubated with crude extracts from lesions of condyloma acuminata,foreskin proteins,and PBS,respectively,followed by phenotypic analysis after9-12days' culture.Results Expression of antigens CD1a,CD80,CD86,MHC-I,MHC-II,CD14,CD54was detected after12days' cul-ture.It was shown that MNCs could be induced to differentiate to mature dendritic cells in our culture system.After incubation with crude extracts from lesions of condyloma acuminata for another9-12days,expression of CD86and HLA-DR was increased on dendritic cells.Conclusions Compared to foreskin and PBS pulsed dendritic cells,expression of CD86and HLA-DR is upregulated on dentritic cells after pulsing with condyloma acuminata lesion proteins.The data suggest that crude extracts from lesions of condyloma acuminata might enhance antigen-pre-senting capacity of dendritic cells and strengthen activation of T lymphocytes.

Objective:To explore the risk factors for lower extremity deep vein thrombosis (DVT) in patients with a spinal cord injury (SCI).Methods:The medical records of 276 hospitalized SCI patients were analyzed retrospectively. They were divided into a DVT group ( n=63) and a no-DVT group ( n=213). Gender, age, blood type, smoking history, surgical history, the time from SCI to admission, cause of SCI, fracture, SCI segments, American Spinal Cord Injury Association grade and complications were compared between the two groups. Binomial logistic regression was used to isolate the risk factors for lower extremity DVT among such patients. Results:Among 84% of the 63 with a lower extremity DVT, it was a calf muscle venous thrombosis. Anemia, hyponatremia and time from SCI to admission (which ranged from 74 to 195 days) were the most serious DVT risk factors.Conclusions:SCI patients are of high risk for DVT, with anemia and hyponatremia being independent risk factors.

Objective:To explore the risk factors for urinary tract infection (UTI) after a spinal cord injury (SCI).Methods:The medical records of 403 SCI patients were analyzed retrospectively. They were divided into UTI group and no-UTI group according to whether they had a UTI at admission. Gender, age, cause of injury, injury level of the spinal cord, voluntary anal contraction, time from injury to admission, American Spinal Injury Association (ASIA) grade, axillary temperature at admission, complications at admission (diabetes, hypertension, fracture of the pelvis, pressure sores or anemia), white blood cell count and urinary bacteria were compared between the two groups. Binary logistic regression was used to highlight the risk factors for a UTI after an SCI.Results:Of the 354 patients included in the final analysis, 62 (17.51%) had a UTI at admission. The regression showed that UTI after an SCI was closely related to an inability to voluntarily contract the anus, anemia, elevated white blood cell count and a high level of bacteria in the urine.Conclusions:Inability to contract the anus, fever, anemia and an elevated white blood cell count are independent indicators of a UTI after an SCI. A temperature ≥37.3°C is a simple indicator of a concentration of bacteria in the urine ≥1266/μL.

Objective:To analyze the diagnostic and prognostic value of routine bone marrow examination in patients with extranodal NK/T-cell lymphoma (ENKTCL) based on PET-CT staging.Methods:Clinical data of 186 patients who received bone marrow biopsy and bone marrow aspiration in Fujian Medical University Union Hospital from 2013 to 2021 were retrospectively analyzed. All patients were divided into bone marrow biopsy + bone marrow aspiration group ( n=186) and PET-CT + bone marrow biopsy group ( n=139). The sensitivity, specificity, positive and negative predictive values were compared between two groups. The data were analyzed and plotted. Survival analysis was performed using Kaplan-Meier method and log-rank test. Results:In the whole cohort, 45 patients were positive for bone marrow biopsy, and 30 of them were positive for bone marrow aspiration. A total of 141 patients who were negative for bone marrow biopsy also achieved negative results for bone marrow aspiration. A total of 139 patients completed PET-CT staging and bone marrow biopsy. And 30 patients were diagnosed with positive bone marrow by PET-CT, in which 22 of them were confirmed positive by bone marrow biopsy. Among 109 patients diagnosed with negative bone marrow by PET-CT, 5 of them were confirmed positive by bone marrow biopsy. All these cases were classified as stage Ⅳ due to distant metastases. PET-CT had a diagnostic sensitivity of 81.5%, a specificity of 92.9%, a positive predictive value of 73.3%, and a negative predictive value of 95.4%. Among early stage (Ⅰ-Ⅱ stage) patients diagnosed with PET-CT, all of them were negative for bone marrow biopsy (the negative predictive value was 100%). In stage Ⅳ patients ( n=55), the 1-year overall survival of patients with bone marrow involvement by bone marrow biopsy or PET-CT ( n=35) compared with their counterparts with the involvement of other organs ( n=20) was 28.7% vs.42.0% ( P=0.13), and 1-year progression free survival rates was 23.2% vs. 23.3% in ( P=0.94). Conclusions:Routine bone marrow biopsy does not change the original staging of patients with early stage ENKTCL based on PET-CT staging. Advanced stage patients with positive bone marrow biopsy tend to obtain worse prognosis, indicating that bone marrow biopsy still has certain value.
