Objective To evaluate the clinical value of ultrasound diagnosis of ovarian endometriosis. Methods 51 cases of 69 mass with ovarian endometriosis confirmed by post-operation and pathologically were enrolled retrospectively. Results The sensitivity of ultrasound diagnosis of ovarian endometriosis was 94.2%(66/69), The accuracy was 75.5% (37/49). Ovarian endometriosis according to ultrasound-image characteristics could be divided into five types: spot-uniform capsule, simplex -cyst, polycystic type, capsule mass and mixed type. In 16.6% symptoms, stripe or star-like blood streams had been found on cyst wall or partition, the highest RI-value was 0.72, the lowest 0.56, and the mean was 0.61.Conclusion Ultrasound is a valuable means for diagnosis of ovarian endometriosis.

Objectives: To compare the performance and outcomes of monopolar electrosurgical conization (MESC) or the loop electrosurgical excision procedure (LEEP) in the treatment of high-grade squamous intraepithelial lesion (HSIL). Methods: This retrospective study included 554 patients diagnosed with HSIL through biopsy. The study used either LEEP or MESC for cervical conization. Additionally, the medical records of these patients, including the basic information, status of the excision margin, cone depth, cone width, fragmentation, complication, and the results of a 6-month follow-up after conization, were reviewed. Results: Compared to MESC, LEEP had a significantly higher rate of positive endocervical margin (3.77 vs. 8.65%; p = 0.018), burn injury of the margin (4.90 vs. 10.38%; p = 0.016) and a lower rate of adequate cone depth (83.40 vs. 89.62%; p = 0.034). In addition, LEEP was significantly more likely to cause fragmentation ( p = 0.000). There was, however, no significant difference in the rate of abnormal cervical cytology and positive high-risk HPV (hrHPV) between these two groups, 6 months after cervical conization. Conclusion: Both LEEP and MESC appeared to be equally effective in the clinical treatment of HSIL. Nonetheless, MESC resulted in a better pathological outcome with regard to the status of the margin, tissue fragmentation, and cone depth.
Aims and Objectives/Purpose/Research Questions: This study investigated the effect of the specific L2 learning experience (i.e., usage, proficiency, and exposure) on cognitive performance in 121 Chinese learners of English. Design/Methodology/Approach: The participants were divided into three groups: beginning, intermediate, and advanced learners. They are homogeneous in background variables (e.g., cultural and educational environment) but heterogeneous in the L2 language experience. They performed three non-linguistic cognitive tasks, tapping into multiple dimensions of cognitive functions in visual and auditory domains. Data and Analysis: Linear mixed-effect models were applied to RT-based analysis (i.e., analysis based on Reaction Time), and linear regression models were used for accuracy-based analysis. In addition, further multiple stepwise regression analyses were conducted to explore the relationships between individuals’ demographics, language experience, and their performance on the attentional tasks. Findings/Conclusions: Three groups were comparable in background measures (e.g., socioeconomic status [SES]) and fundamental cognitive abilities (e.g., working memory and IQ), but differed in specific subcomponents of cognitive functions. Specifically, compared with beginning learners, advanced learners who had a longer length of L2 usage and higher proficiency showed better inhibitory control; intermediate learners who received intensive L2 exposure and had higher proficiency showed better-switching ability and attentional disengagement. Intermediate and advanced learners were comparable in cognitive performance. The results suggest that early adulthood L2 learners experience similar cognitive effects of bilingualism, which are modulated by specific language experience. Originality: This is one of the first bilingual studies to incorporate both visual and auditory cognitive functions, while providing additional analyses to investigate the other components of cognitive control. Significance/Implications: The results contribute to the understanding of the key aspects of the L2 learning experience that contribute to the emergence of the cognitive effects of young adult learners.
Adopting prospective, multi-center, random, single-blind and equal rank-control methods,226 patients with rlieumatoid arthritis (RA) were divided into two groups. The 114 patients ot the test groupwere treated with oral sustained release tablets of Tripterygium Wiltordii (TW-SR) , 2 tablets twice a day for4 weeks, 112 patients of the control group received tablets of Tripterygium Wiltordii(TW) orally 2 tablets 3times per day for 4 weeks. Testing results showed thetotal effective rates of the two groups were 92 . 11%and 90. 65 % , respectively (P 0. 05) . The adverse reaction rate of TW-SR was 20 . 18% , which was low-er than that of TW group of 70. 54% (P 0. 01 ) . Results of pre-clinical pharmacologic experimental studydemonstrated that TW-SR has obvious anti-inflammatory , analgesic and immunosuppressive actions the sameas TW, while the toxicity of TW-SR was less than that of TW significantly.
Background We documented previously the entity of trichloroethylene (TCE) hypersensitivity syndrome (THS) in occupational workers. Objectives To identify the culprit causative compound, determine the type of hypersensitivity of THS, and establish a screening test for subjects at risk of THS. Methods TCE and its main metabolites chloral hydrate (CH), trichloroethanol (TCOH) and trichloroacetic acid (TCA) were used as allergens at different concentrations in skin patch tests. The study included 19 case subjects diagnosed with occupational THS, 22 control healthy workers exposed to TCE (exposure >12 weeks), and 20 validation new workers exposed to TCE for <12 weeks free of THS. All subjects were followed-up for 12 weeks after the patch test. Results The highest patch test positive rate in subjects with THS was for CH, followed by TCOH, TCA and TCE. The CH patch test positive rate was 100% irrespective of CH concentrations (15%, 10% and 5%). The TCOH patch test positive rate was concentration-dependent (89.5%, 73.7% and 52.6% for 5%, 0.5% and 0.05%, respectively). Lower patch test positive rates were noted for TCA and TCE. All patch tests (including four allergens) were all negative in each of the 22 control subjects. None of the subjects of the validation group had a positive 15% CH patch test. Conclusions Chloral hydrate seems to be the culprit causative compound of THS and type IV seems to be the major type of hypersensitivity of THS. The CH patch test could be potentially useful for screening workers at risk of THS.
Abstract This paper is a proposal for an update on the characterization of cognitive impairments associated with sporadic cerebral small vessel disease (SVD). We pose a series of questions about the nature of SVD‐related cognitive impairments and provide answers based on a comprehensive review and meta‐analysis of published data from 69 studies. Although SVD is thought primarily to affect executive function and processing speed, we hypothesize that SVD affects all major domains of cognitive ability. We also identify low levels of education as a potentially modifiable risk factor for SVD‐related cognitive impairment. Therefore, we propose the use of comprehensive cognitive assessments and the measurement of educational level both in clinics and research settings, and suggest several recommendations for future research.
