Objective To investigate patients in gynecological endocrinology clinic with the following three pieces of information: how did they provide their symptom information, how did they understand diagnostic and therapeutic information, and what was their attitude towards the visit, and to get to know about the situation and problems in doctor-patient communication, so as to aim directly at improving the efficiency of diagnosis and treatment. Methods A total of 403 patients, who visited Prof. HAN Zi-yan’s clinic in the hospital from April to August 2010, were evaluated using self-edited Assessment on Doctor-patient Communication in Gynecological Endocrinology Outpatient Clinic. Results a) As to the situation of patients providing symptom information as well as understanding diagnostic and therapeutic information, when doctor asked, only 29% (118/403) of patients could narrate their treatment history clearly, and 38% (152/403) could tell their examination history exactly. After doctors’ explanation, only 21% (86/403) understood their examination results correctly, and 27% (108/403) understood management and therapeutic advice. The result of correlation analysis showed the accuracy of patients in providing disease information and accepting diagnostic and therapeutic information was higher in patients aged from 21 to 40 rather than those younger than 20, in patients well- educated rather than those with little education at the primary school, and in patients who were also engaged in medical work, All differences were significant (all Plt;0.05); and b) As to patients’ attitude towards visit, 55% (222/403) of patients hoped to get more attention from doctor, and 37.5% (151/403) overly expected the visit. Conclusion In the professor’s gynecological endocrinology outpatient clinic, many patients can’t clearly provide their treatment and examination history, neither understand exam situation and therapeutic advice at that visit, which are influenced by their age, education and occupation. In addition, psychological needs of patients should be concerned, too
【摘要】 目的 分析手术治疗垂体瘤患者长期临床恢复以及生活质量改善情况。 方法 回顾性分析2007年12月-2008年9月手术治疗的103例垂体瘤患者术前以及术后长期随访资料，使用SF-36量表对术前、术后患者生活质量进行评估，分析手术治疗前后患者症状、激素水平恢复情况以及生活质量改善情况，并进一步分析肿瘤大小、侵袭程度对术后生活质量的影响。 结果 术后头痛症状消失52例，视力改善76例，其他症状具有不同程度改善；术后SF-36生活质量评估结果显示，患者除精神健康外的7个维度（生理机能、生理职能、躯体疼痛、一般健康状况、精力、社会功能、情感职能）均有明显改善（P＜0.05），不同肿瘤大小及侵袭程度的患者术后生活质量评分均无统计学意义（P＞0.05），垂体功能完全恢复者生活质量评分高于垂体功能低下者（P＜0.05）。 结论 显微手术治疗垂体瘤患者可明显改善患者的一般症状、提高患者的生活质量，单纯肿瘤的大小和侵袭程度对术后生活质量的影响程度较小，术后垂体功能的恢复程度明显影响患者的生活质量，垂体瘤术后患者的激素长期替代治疗尚需进一步加强。【Abstract】 Objective To analyze the long-term clinical recovery and quality of life (QoL) in patients with pituitary adenoma treated by microneurosurgery. Methods The clinical data of 103 patients undergoing microneurosurgery from December 2007 to September 2008 were retrospectively analyzed, health-related questionnairs (SF-36) were used to assess the QoL. The post-surgery recovery of symptoms, endocrine function, and QoL were compared with those of pre-surgery, then the correlation between tumor size, invasive behavior, and QoL were analyzed. Results Headache disappeared in 52 patients. Visual symptoms improved in 76 patients. Other symptoms were also improved. Seven concepts (physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotioning) were improved after surgery (Plt;0.05). The eight health concepts of SF-36 showed no significant difference between patients with different tumor size and invasive behavior (Pgt;0.05). Differences were considered statistically significant between normal and abnormal pituitary function groups after surgery(Plt;0.05) in all concepts. Conclusion Microneurosurgical treatment can improve the general symptoms and the QoL. The tumor size and invasion have little influence on the QoL after surgery, but the improvement of hormone deficiency has influence on the QoL significantly. More attention should be given to the long-term hormone replacement therapy after the pituitary adenoma surgery.
Photoplethysmography (PPG) is often affected by interference, which could lead to incorrect judgment of physiological information. Therefore, performing a quality assessment before extracting physiological information is crucial. This paper proposed a new PPG signal quality assessment by fusing multi-class features with multi-scale series information to address the problems of traditional machine learning methods with low accuracy and deep learning methods requiring a large number of samples for training. The multi-class features were extracted to reduce the dependence on the number of samples, and the multi-scale series information was extracted by a multi-scale convolutional neural network and bidirectional long short-term memory to improve the accuracy. The proposed method obtained the highest accuracy of 94.21%. It showed the best performance in all sensitivity, specificity, precision, and F1-score metrics, compared with 6 quality assessment methods on 14 700 samples from 7 experiments. This paper provides a new method for quality assessment in small samples of PPG signals and quality information mining, which is expected to be used for accurate extraction and monitoring of clinical and daily PPG physiological information.
Ultrasound guided percutaneous interventional therapy has been widely used in clinic. Aiming at the problem of soft tissue deformation caused by probe contact force in robot-assisted ultrasound-guided therapy, a real-time non-reference ultrasound image evaluation method considering soft tissue deformation is proposed. On the basis of ultrasound image brightness and sharpness, a multi-dimensional ultrasound image evaluation index was designed, which incorporated the aggregation characteristics of the organization. In order to verify the effectiveness of the proposed method, ultrasound images of four different models were collected for experiments, including prostate phantom, phantom with cyst, pig liver tissue, and pig liver tissue with cyst. In addition, the correlation between subjective and objective evaluations was analyzed based on Spearman’s rank correlation coefficient. Experimental results showed that the average evaluation time of a single image was 68.8 milliseconds. The evaluation time could satisfy real-time applications. The proposed method realizes the effective evaluation of real-time ultrasound image quality in robot-assisted therapy, and has good consistency with the evaluation of supervisors.
During long-term electrocardiogram (ECG) monitoring, various types of noise inevitably become mixed with the signal, potentially hindering doctors' ability to accurately assess and interpret patient data. Therefore, evaluating the quality of ECG signals before conducting analysis and diagnosis is crucial. This paper addresses the limitations of existing ECG signal quality assessment methods, particularly their insufficient focus on the 12-lead multi-scale correlation. We propose a novel ECG signal quality assessment method that integrates a convolutional neural network (CNN) with a squeeze and excitation residual network (SE-ResNet). This approach not only captures both local and global features of ECG time series but also emphasizes the spatial correlation among ECG signals. Testing on a public dataset demonstrated that our method achieved an accuracy of 99.5%, sensitivity of 98.5%, and specificity of 99.6%. Compared with other methods, our technique significantly enhances the accuracy of ECG signal quality assessment by leveraging inter-lead correlation information, which is expected to advance the development of intelligent ECG monitoring and diagnostic technology.

ObjectiveThis study aims to conduct a systematic review and quality assessment of published domestic and foreign studies on the pharmacoeconomics of Chinese patent medicines, with the goal of identifying relevant issues and proposing improvement suggestions. MethodsThe methods used in this study involved systematic searches of the CNKI, WanFang Data, VIP, and PubMed databases for domestic and foreign studies related to the pharmacoeconomics of Chinese patent medicines, with a search deadline of May 20, 2022. The studies were evaluated systematically based on various aspects such as title, year, author, journal, research perspective, research type, disease area, research object, research design type, research method, application model, model calibration, sensitivity analysis, cost calculation, effectiveness indicators, and adverse reaction comparison. The evaluation of report quality and methodological quality was conducted using the consolidated health economic evaluation reporting standards 2022 (CHEERS 2022) and the quality of health economic studies (QHES) tools, respectively. ResultsThis study included a total of 249 articles, including 247 in Chinese and 2 in English. The first article on the pharmacoeconomics of Chinese patent medicine was published in 2000. The diseases studied covered 59.26% of the ICD-11 disease areas. Articles reporting on the research perspective accounted for 16.87% of the total number of studies, while 32.4% of studies provided an explanation of the research type. The main method used was cost-effectiveness analysis, accounting for 86.75% of the studies, and the main cost component was direct medical costs, accounting for 89.56%. The primary effectiveness indicator was the overall effective rate, accounting for 78.31% of the studies. The average compliance rate with the CHEERS 2022 standard was 43.58%, and the average QHES score was 56.7. ConclusionA considerable part of the existing research on the pharmacoeconomics of traditional Chinese medicine (TCM) suffers from problems such as the lack of research methods or non-standardized methods. Therefore, the relevant research abilities of researchers who conduct TCM pharmacoeconomic research need to be improved.
Objective To compare the application effects of three psychometric instruments including SF-36, FLIC and QOL-LC in measuring the quality of life of patients with liver cancer. Methods A total of 105 in-patients with liver cancer selected from 2010 to 2011 were included. The quality of life was measured by FLIC, SF-36 and QOL-LC, respectively, and the reliability, validity and responsiveness were calculated and analyzed. Results The reliability and validity of QOL-LC were better than those of SF-36 and FLIC. Both QOL-LC and FLIC showed significant differences in responsiveness based on the changes of physical function and overall quality of life (QOL-LC: t=5.08, P=0.000, t=3.16, P=0.002; FLIC: t=4.02, P=0.000, t=2.21, P=0.030). Except for general health and mental health, the other domains of SF-36 showed significant differences in changes after treatment (physical function: t=5.94, P=0.000; physical role: t=3.07, P=0.003; body pain: t=3.21, P=0.002; vitality: t=3.22, P=0.002; social role: t=2.60, P=0.012; emotional role: t=3.28, P=0.002). Conclusion QOL-LC is a specific scale for liver cancer, and it should be used preferentially. SF-36 and FLIC can measure the general state of quality of life and can be used in patients with liver cancer when specific scale is not available.
