ABSTRACT
Objective@#Subthreshold attention-deficit/hyperactivity disorder (ADHD) has been suggested to be a “morbid condition” which also needs medical attention. @*Methods@#The present study recruited 89 children with subthreshold ADHD (sADHD), 115 children with diagnosed ADHD (cADHD), and 79 healthy controls (HC) to explore the clinical manifestation, executive functions (EFs) of sADHD, and the caregiver strain. The clinical manifestation was evaluated through clinical interviews and parent-reports. Executive functions were assessed both experimentally and ecologically. Caregiver strain was measured by a parent-reported questionnaire. @*Results@#For the clinical manifestation, both sADHD and cADHD indicated impairments when compared with HC. The comorbidities and the scaled symptoms indicated that the externalizing behaviors were relatively less serious in sADHD than cADHD, whereas the internalizing behaviors between two groups were comparable. For ecological EFs, sADHD scored between cADHD and HC in inhibition and working memory. For experimental EFs, sADHD was comparable to cADHD in inhibition, shifting, and was worse than cADHD in verbal working memory. For the caregiver strain, all scores of sADHD were between that in cADHD and that in HC. @*Conclusion@#Our present findings supported the suggestion of subthreshold ADHD as “morbid condition,” which should be treated with caution in clinical practice, especially for the internalizing behaviors and some key components of EFs.
ABSTRACT
Objective To analyze muscle pre-activation and surface electromyography (sEMG) characteristics of knee and ankle joints of long-term Tai Chi practitioners during brush-knee twist-step and normal walking, and explore the neuromuscular control strategies of Tai Chi to prevent falls. Methods Vicon motion capture system, Kistler force plate, and Noraxon sEMG system were synchronously used to collect the EMG signals of the rectus femoris, biceps femoris, tibialis anterior muscle, lateral head of gastrocnemius and body posture information during brush-knee twist-step and normal walking. The pre-activation and co-contraction of knee and ankle joints were calculated by integrated EMG of the rectus femoris/biceps femoris, tibial anterior/lateral gastrocnemius muscles. Results Compared with normal walking, the average time of brush-knee twist-step in four phases was significantly increased. There was a significant difference in the percentage of time in four phases. The knee joint co-contraction level and pre-activation level decreased, and the ankle joint co-contraction level and pre-activation level increased. Conclusions Long-term Tai Chi exercises may increase the activation level of the muscles around knee joints and enhance the synergy in muscle groups to help stabilize the joint. The results provide references for rehabilitation assessment and training of neuromuscular control disorders.
ABSTRACT
Objective To profile methylation alterations of cytosine-phosphate-guanosine islands (CGI)in epithelial ovarian cancer and investigate its applications for finding new candidate tumor markers.Methods Cancer cells were obtained by lager microdissection from 20 tissues of frozen-preserved epithelial ovarian tumors.Primary cultured epithelial cells were isolated from 5 tissues of normal ovaries.Differential methylation hybridization(DMH)based on microarray assay Was conducted using DNA to construct the aberrant DNA methylation pattern of epithelial ovarian cancer.MethyLight was conducted to verify the methylation status of 7 hypomethylated promoter CGI detected by DMH in tumor tissues of 87 patients with epithelial ovarian cancer and 42 patients with benigh ovarian diseases.Results The aberrant DNA methylation pattem of epithelial ovarian cancer were included 182 hypermethylated loci and 64 hypomethylated loci,of which the positive loci located more than 25%arrays were 18 and 31,respectively.The methylation ratio of gene LSM2,EGFLAM and CDKN2A in tissue DNA of patients with epithelial ovarian cancer and benign ovarian diseases Was 11%(10/87)versus 33%(14/42),8%(7/87)versus 21%(9/42),9%(8/87)versus 31%(13/42),respectively,which Was significantly decreased in tissues DNA of ovarian cancer than that from benigh ovarian diseases(P＜0.05).Conclusions The aberrant DNA methylation pattern of epithelial ovarian cancer is important for finding new cancer related genes.The promoter CGI of gene ISM2,EGFIAM and CDKN2A may be Hovel candidate for ovarian cancerspecific hypomethylated tumor markers.
ABSTRACT
Objective To investigate clinicopathological features of endometriosis-associated epithelial ovarian carcinoma.Methods Retrospective follow-up study,clinicopathological data from patients with ovarian epithelial carcinoma were retrieved,analyzed and compared.Among the 727 cases,34 were found to originate from endometriosis (group A),33 were found to have co-existing ovarian endometriosis (group B),and the remaining 660 had no ovarian endometriosis at all (group C).Result Seven hundred and twenty-seven epithelial ovarian carcinoma patients were identified and their ehnicopathological data retrieved.Sixty-seven (9.2%) of these cases were found to have coexisting endometriosis.The frequency of malignant tumors arising from ovarian endometriosis in this case series was estimated to be 0.87% (34/3890).The mean (standard deviation) age in groups A,B,and C were(47.2±1.3),(47.8±1.2),(51.2±0.4) years,respectively,with patients in group C being significantly older (P = 0.013).Patients with coexisting ovarian endometriosis were mostly diagnosed at stage Ⅰ (P = 0.000)and having subtype of clear-cell (P =0.000),while other patients were mostly diagnosed at stage Ⅲ (P =0.001),and having subtype of serous carcinoma (P =0.000).The estrogen receptor (ER) positivity was significantly lower in groups A and B than that in group C (22.2%,31.6% vs 43.9%;P =0.018),but the difference in positivity of progestogen receptor among the three groups did not reach statistical significance (22.2%,15.8% vs 35.5%;P =0.082).While the five-year overall survival rate for all patients was 55.6%,significant difference in overall survival among the three groups was found 78.9%,92.8%,51.9%,respectively,for groups A,B and C (P =0.000).Conclusion Patients of endometriosis-associated epithelial ovarian carcinoma,especially patients with tumors arising from endometriosis,were found to be younger,having a significant lower stage and a better survival,and were mostly diagnosed with the subtype of clear-cell.
ABSTRACT
Objective:This study investigated the prognostic significance of age at diagnosis, stage, tumor subtype, pelvic lymph node metastasis (PLNM), lymph-vascular space involvement (LVSI), presence or absence of deep cervical stromal invasion (DCSI) in stage ⅠB-ⅡA cervical cancer patients. It also investigated the inter-relationship among these factors. Methods: 152 patients treated with radical hysterectomy plus pelvic lymphadenectomy were followed up for a median of 49 months and were evaluated retrospectively. Results: The 5-year overall survival rate was 84.8%. The distribution of age at diagnosis is of bimodal shape, peaking at 42 and 68 years, respectively. Tumor subtype, PLNM, DCSI, and LVSI were found to be significant prognostic factors individually. After multivariate analysis, only tumor subtype and PLNM were found to be independent, significant prognostic factors for survival. The prognostic importance of LVSI appeared to be eclipsed by the presence of PLNM. DCSI was statistically related with FIGO stage, LVSI and PLNM. Conclusion: Tumor subtype and PLNM are the two most important independent prognostic factors for stages ⅠB-ⅡA cervical cancer. Some prognostic factors are inter-related and may reflect different facets of tumor progression.
