The results showed that, regarding brain function, some dimensions of social adjustment were associated with the insula, and some regions of the frontal and occipital lobes. Self-adjustment and satisfaction required activation of the middle frontal gyrus, while career adjustment and academic adjustment required inhibition of the inferior frontal gyrus and lingual gyrus, respectively. Decreased metabolic activity of the lingual gyrus was beneficial for obtaining satisfaction. Regarding brain structure, the total score and some dimensions of social adaptation were associated with the gray matter of portions of the temporal and parietal lobes. The superior temporal gyrus was associated with the total social adjustment and satisfaction score, the middle temporal gyrus with campus-life adjustment and satisfaction, and the post central gyrus and the inferior parietal lobule with emotional adjustment. The changes in the gray matter volume of these brain regions to a certain extent reflected socially adaptive behaviors. The results suggest that social adaptability is associated with various brain regions dispersed among both hemispheres of the brain, and requires synergistic inter-actions between multiple brain regions and both brain hemispheres.展开更多

METHODS: Randomized, double blind, placebo-controlled trial co mparing a single 25-μg outpatient intravaginal dose of misoprostol to placebo in pregnant women with Bishop scores less than 9 at 40 weeks or greater. After p lacement of the study medication, subjects were permitted to go into spontaneous labor unless an indication for induction developed. Analysis was by intent to t reat. The interval to delivery, defined as the time from medication placement to delivery, was compared by Student t test and by survival analysis with the log -rank test. RESULTS: Thirty-three women were randomly assigned to receive miso prostol, and 35 were assigned to receive placebo. The mean interval to delivery was significantly less in the misoprostol group, 4.2 ±.4.1 compared with 6.1 ± .3.6 days, P = .04. The interval to delivery for only the nulliparous patients w as significantly less in the misoprostol group, 4.2 ±.4.0 compared with 7.2 ±. 3.7 days, P = .02. The survival curves for the interval to delivery were signifi cantly different (P = .04 by log-rank test) with 4.1 days median interval to de livery for misoprostol compared with 9.2 days for placebo. There were no adverse outcomes in either group. CONCLUSION: A single 25-μg outpatient intravaginal dose of misoprostol is effective in decreasing the interval to delivery in women with unfavorable cervices at term.展开更多

Sarcoidosis is a multisystem disease and can be confused with benign or malignant tumors. In patients with recurrent gynecologic cancer, liver and intrathoracic lesions should undergo a biopsy to rule in metastatic malignancy, as clinical findings and CAT scan results may represent other disease processes. Case. A 67 year old woman had a total abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic and periaortic lymphadenectomy, and peritoneal cytology in 2001 for Stage I B grade 1 adenocarcinoma of the endometrium. She developed a vaginal recurrence in 2005. A CT scan of lungs, abdomen, and pelvis revealed extensive mediastinal adenopathy and multiple space occupying hepatic lesions worrisome for metastatic disease. A needle biopsy of the largest liver lesion revealed sarcoidosis. Conclusion. Sarcoid lesions may mimic metastatic disease in patients with malignancy, potentially leading to delayed and/or inappropriate therapy.展开更多

文摘With the rapid advancement of wearable devices,Human Activities Recognition(HAR)based on these devices has emerged as a prominent research field.The objective of this study is to enhance the recognition performance of HAR by proposing an LSTM-1DCNN recognition algorithm that utilizes a single triaxial accelerometer.This algorithm comprises two branches:one branch consists of a Long and Short-Term Memory Network(LSTM),while the other parallel branch incorporates a one-dimensional Convolutional Neural Network(1DCNN).The parallel architecture of LSTM-1DCNN initially extracts spatial and temporal features from the accelerometer data separately,which are then concatenated and fed into a fully connected neural network for information fusion.In the LSTM-1DCNN architecture,the 1DCNN branch primarily focuses on extracting spatial features during convolution operations,whereas the LSTM branch mainly captures temporal features.Nine sets of accelerometer data from five publicly available HAR datasets are employed for training and evaluation purposes.The performance of the proposed LSTM-1DCNN model is compared with five other HAR algorithms including Decision Tree,Random Forest,Support Vector Machine,1DCNN,and LSTM on these five public datasets.Experimental results demonstrate that the F1-score achieved by the proposed LSTM-1DCNN ranges from 90.36%to 99.68%,with a mean value of 96.22%and standard deviation of 0.03 across all evaluated metrics on these five public datasets-outperforming other existing HAR algorithms significantly in terms of evaluation metrics used in this study.Finally the proposed LSTM-1DCNN is validated in real-world applications by collecting acceleration data of seven human activities for training and testing purposes.Subsequently,the trained HAR algorithm is deployed on Android phones to evaluate its performance.Experimental results demonstrate that the proposed LSTM-1DCNN algorithm achieves an impressive F1-score of 97.67%on our self-built dataset.In conclusion,the fusion of temporal and spatial information in the measured data contributes to the excellent HAR performance and robustness exhibited by the proposed 1DCNN-LSTM architecture.
文摘KEY POINTSTraditional stretching routines performed during warm-up procedures before exercise can increase flexibility for a short time,but there is little scientific evidence that such routines can improve exercise performance,reduce delayed-onset muscular soreness,or prevent injuries.Stretching on a regular basis,e.g.,3-5 days/week,away from the exercise environment may be effective in improving flexibility and some types of exercise performance,and it may reduce injury risk,but further research is required to validate this concept.Passive stretching for 15-30 seconds is more effective for increasing flexibility than stretching for shorter durations and is equally effective as stretching for longer periods.
文摘This study investigated the neural basis of social adjustment using multimodal brain imaging and social-adjustment measurements to analyze functional and structural brain features during social adjustment in college students. The results showed that, regarding brain function, some dimensions of social adjustment were associated with the insula, and some regions of the frontal and occipital lobes. Self-adjustment and satisfaction required activation of the middle frontal gyrus, while career adjustment and academic adjustment required inhibition of the inferior frontal gyrus and lingual gyrus, respectively. Decreased metabolic activity of the lingual gyrus was beneficial for obtaining satisfaction. Regarding brain structure, the total score and some dimensions of social adaptation were associated with the gray matter of portions of the temporal and parietal lobes. The superior temporal gyrus was associated with the total social adjustment and satisfaction score, the middle temporal gyrus with campus-life adjustment and satisfaction, and the post central gyrus and the inferior parietal lobule with emotional adjustment. The changes in the gray matter volume of these brain regions to a certain extent reflected socially adaptive behaviors. The results suggest that social adaptability is associated with various brain regions dispersed among both hemispheres of the brain, and requires synergistic inter-actions between multiple brain regions and both brain hemispheres.
文摘OBJECTIVE: To estimate the effect of outpatient administration of a single d os e of vaginal misoprostol at term on the interval to delivery in women with unfav orable cervices. METHODS: Randomized, double blind, placebo-controlled trial co mparing a single 25-μg outpatient intravaginal dose of misoprostol to placebo in pregnant women with Bishop scores less than 9 at 40 weeks or greater. After p lacement of the study medication, subjects were permitted to go into spontaneous labor unless an indication for induction developed. Analysis was by intent to t reat. The interval to delivery, defined as the time from medication placement to delivery, was compared by Student t test and by survival analysis with the log -rank test. RESULTS: Thirty-three women were randomly assigned to receive miso prostol, and 35 were assigned to receive placebo. The mean interval to delivery was significantly less in the misoprostol group, 4.2 ±.4.1 compared with 6.1 ± .3.6 days, P = .04. The interval to delivery for only the nulliparous patients w as significantly less in the misoprostol group, 4.2 ±.4.0 compared with 7.2 ±. 3.7 days, P = .02. The survival curves for the interval to delivery were signifi cantly different (P = .04 by log-rank test) with 4.1 days median interval to de livery for misoprostol compared with 9.2 days for placebo. There were no adverse outcomes in either group. CONCLUSION: A single 25-μg outpatient intravaginal dose of misoprostol is effective in decreasing the interval to delivery in women with unfavorable cervices at term.
文摘Background. Sarcoidosis is a multisystem disease and can be confused with benign or malignant tumors. In patients with recurrent gynecologic cancer, liver and intrathoracic lesions should undergo a biopsy to rule in metastatic malignancy, as clinical findings and CAT scan results may represent other disease processes. Case. A 67 year old woman had a total abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic and periaortic lymphadenectomy, and peritoneal cytology in 2001 for Stage I B grade 1 adenocarcinoma of the endometrium. She developed a vaginal recurrence in 2005. A CT scan of lungs, abdomen, and pelvis revealed extensive mediastinal adenopathy and multiple space occupying hepatic lesions worrisome for metastatic disease. A needle biopsy of the largest liver lesion revealed sarcoidosis. Conclusion. Sarcoid lesions may mimic metastatic disease in patients with malignancy, potentially leading to delayed and/or inappropriate therapy.

文摘To the Editor:Contemporary guidelines recommend primary percutaneous coronary intervention(PPCI)as the gold-standard reperfusion modality in patients with ST-segment elevation myocardial infarction(STEMI)within 12 h of symptom onset.However,in realworld clinical practice,the implementation of PPCI faces substantial operational challenges,particularly in resource-limited settings,such as inadequate availability of specialized cardiac catheterization teams with requisite procedural expertise or the complete absence of coronary intervention capabilities in numerous rural healthcare facilities across China.Consequently,fibrinolytic therapy remains the predominant reperfusion strategy for STEMI management in county-level hospitals,with particularly high utilization rates observed in geographically remote regions.[3,4]Furthermore,our previous study revealed that 42.5%of STEMI patients fail to receive any form of evidence-based reperfusion therapy,representing a critical gap in optimal care delivery.To elucidate the prognostic implications of these treatment pathways within China’s unique healthcare system,this study aimed to compare the long-term outcomes among STEMI patients receiving PPCI,fibrinolysis,and no reperfusion therapy using data from the China Acute Myocardial Infarction Registry(CAMI Registry,clinicaltrials.gov,NCT01874691).
