摘要：

Preventive medicine has been incorporated in the medical school curriculum, but its effectiveness and the factors that affect it are yet to be widely looked into in the context of Malaysia. We aimed to measure the familiarity with, perception about the importance to learn, and the ability to practice preventive medicine as well as its determinants among the medical students in Malaysia. Thus, a cross sectional study was conducted through an anonymous online survey among 387 randomly selected final year medical students of four large public medical schools in Malaysia from March to September 2014. Of the total sample, only 340 (response rate 87.8%) gave a written informed consent and took part in the survey. The familiarity of the sample with preventive medicine was measured in 19 preventive medicine areas, and their perception about the importance of preventive medicine and their ability to practice it were gauged on a Likert scale (low score indicates disagreement and high indicates agreement). Descriptive statistical analysis was performed, followed by logistic regression. The mean age of the respondents was 23.7 (SD 0.77) years, and 61.2% (n = 208) of them were females. Results showed that 22.9% of the sample (n= 78) had a low familiarity with preventive medicine, whereas 76.8% (n = 261) had a high familiarity. The study sample specified that among all the preventive medicine subjects, screening and control as well as smoking cessation and immunization are “extremely important to learn.” In univariable analysis, being a female, medical school, family size, and perception about the importance to learn preventive medicine were associated with the ability to practice it. In multivariable analysis, the perception towards the importance to learn preventive medicine was the only significant determinant: aOR (adjusted odds ratio) for those who “agreed” 17.28 (95% CI aOR 4.44 – 67.26, P<0.001) and for “strongly agreed” 35.87 (95% CI aOR 8.04 – 159.87, P<0.001). Considering these findings, the familiarity of medical students with preventive medicine should be increased. The perception about the importance to learn preventive medicine is a strong determinant for the ability to practice it.

《医学前沿（英文）》 2015年 第9卷 第2期   页码 251-259 doi: 10.1007/s11684-015-0393-z

摘要：

Unhealthy behaviors of medical students influence their attitudes toward preventive counseling. The burden of chronic diseases is continually growing in developing countries, emphasizing the need for the increased role of general practitioners in preventive counseling. The objective of this study was to describe the effect of medical training on the risk profiles and attitudes of medical students toward preventive counseling in a Colombian university. Students in their first and fifth years of training were surveyed using the “Healthy Doctor= Healthy Patient” questionnaire to assess counseling attitudes; personal practices, such as risky drinking, smoking, inadequate nutrition, and non-compliance with physical activity recommendations; and the university environment. The association among these components was estimated, as well as the effect of the university environment. Risky drinking and smoking decreased from first to fifth year (59.3% vs. 37.1%, P = 0.021 and 31.5% vs. 25.9%, P = 0.51, respectively), whereas inadequate nutrition and non-compliance with physical activity recommendations increased. Physical activity (PA) was associated with positive counseling attitude (ORs: nutrition 7.6; alcohol 5.2; PA 10.6). Areas governed by institutional policies that are emphasized in the curriculum positively affected student practices. PA promoted preventive counseling and healthy lifestyles most effectively. Universities should therefore strengthen their preventive medicine curricula and modify social determinants.

摘要：

With the transformation of modern medicinal pattern, medical studies are confronted with methodological challenges. By analyzing two methodologies existing in the study of physical matter system and information system, the article points out that traditional Chinese medicine (TCM), especially the treatment based on syndrome differentiation, embodies information conception of methodological positions, while western medicine represents matter conception of methodological positions. It proposes a new way of thinking about combination of TCM and western medicine by combinating two kinds of methodological methods.

《医学前沿（英文）》 2008年 第2卷 第2期   页码 143-146 doi: 10.1007/s11684-008-0027-9

摘要： Twenty-seven patients with severe colon trauma treated in the Shaoxing People’s Hospital from 1995 to 2006 were retrospectively analyzed. The patients with severe tunica muscularis injury were treated by medical glue combined with the greater omentum during operations. The initial result was encouraging. All patients were cured with no anastomotic leakage or abscess. Therefore, reasonable use of medical glue combined with the greater omentum can not only improve the curative rate but also reduces postoperative complications for patients with colon injury.

摘要： As a promising method in artificial intelligence, deep learning has been proven successful in several domains ranging from acoustics and images to natural language processing. With medical imaging becoming an important part of disease screening and diagnosis, deep learning-based approaches have emerged as powerful techniques in medical image areas. In this process, feature representations are learned directly and automatically from data, leading to remarkable breakthroughs in the medical field. Deep learning has been widely applied in medical imaging for improved image analysis. This paper reviews the major deep learning techniques in this time of rapid evolution and summarizes some of its key contributions and state-of-the-art outcomes. The topics include classification, detection, and segmentation tasks on medical image analysis with respect to pulmonary medical images, datasets, and benchmarks. A comprehensive overview of these methods implemented on various lung diseases consisting of pulmonary nodule diseases, pulmonary embolism, pneumonia, and interstitial lung disease is also provided. Lastly, the application of deep learning techniques to the medical image and an analysis of their future challenges and potential directions are discussed.

《机械工程前沿（英文）》 2011年 第6卷 第1期   页码 40-44 doi: 10.1007/s11465-011-0204-4

摘要：

Wireless capsule endoscopy has become a common procedure for diagnostic inspection of gastrointestinal tract. This method offers a less-invasive alternative to traditional endoscopy by eliminating uncomfortable procedures of the traditional endoscopy. Moreover, it provides the opportunity for exploring inaccessible areas of the small intestine. Current capsule endoscopes, however, move by peristalsis and are not capable of detailed and on-demand inspection of desired locations. Here, we propose and develop two wireless endoscopes with maneuverable vision systems to enhance diagnosis of gastrointestinal disorders. The vision systems in these capsules are equipped with mechanical actuators to adjust the position of the camera. This may help to cover larger areas of the digestive tract and investigate desired locations. The preliminary experimental results showed that the developed platform could successfully communicate with the external control unit via human body and adjust the position of camera to limited degrees.

《能源前沿（英文）》 2008年 第2卷 第1期   页码 1-13 doi: 10.1007/s11708-008-0016-3

摘要： Implantable medical devices (IMDs) are critically requested for the survival of patients subject to certain serious diseases such as bradycardia, fibrillation, diabetes, and disability, etc. Appropriate working of an active implantable medical device (IMD) heavily relies on the continuous supply of electricity. In this sense, long-term powering and recharging of an IMD via a highly safe, efficient and convenient way is, therefore, extremely important in clinics. Several conventional batteries, such as lithium cell, nuclear cell and bio-fuel cell, etc., have been developed to power IMDs. Meanwhile, the recharge of IMD from outside of the human body is also under investigation. In this paper, some of the most typical IMD batteries are reviewed. Their advantages and disadvantages are compared. In addition, several emerging innovations to recharge or directly drive the implanted batteries, including electromagnetic energy transmission, piezoelectric power generation, thermoelectric devices, ultrasonic power motors, radio frequency recharging and optical recharging methods, etc., are also discussed. Some fundamental and practical issues thus involved are summarized, and future prospects in this area are made.

《医学前沿（英文）》 2016年 第10卷 第4期   页码 473-480 doi: 10.1007/s11684-016-0479-

摘要：

Aiming to control rising medical expenditures and help improve China’s healthcare systems, this study examined whether a cap-based medical insurance scheme with shared financial interest between the insurance and healthcare providers is effective in containing hospitals’ C-section medical expenditures. We used 6547 caesarean delivery case records from a teaching tertiary-level general public hospital located in Wuxi, China (2004–2013), and used the Chow test to investigate the possibility of significant variation in mean medical expenditures for caesarean deliveries pre- and post-reform. We also used paired sample t-tests and linear regression models to compare the mean medical expenditures between insured and uninsured women undergoing caesarean delivery during the post-reform period. After the scheme’s implementation, medical expenditures for caesarean deliveries declined and the medical expenditures of women covered by the scheme were significantly lower than those of uninsured patients. These findings indicated the scheme’s effectiveness in minimizing caesarean delivery expenditures. The cap-based medical insurance scheme with shared financial interest between insurance and healthcare providers would likely steer healthcare providers’ behaviors in a more cost-effective direction.

摘要：

Medicine has encountered unprecedented problems associated with changes in nature, society, and environment, as well as with new human quests for survival, longevity, and health. In the meantime, the development of medicine is facing challenges that resulted from the over-division and specialization of disciplines and the fragmentation of medical knowledge. To construct a new medical system that is more suitable for human health and disease treatment, holistic integrative medicine (HIM), which regards the human body as a holistic entity, organically integrates the most advanced knowledge and theories in each medical field and the most effective practices in various clinical specialties to revise and adjust on the basis of social, environmental, and psychological conditions. HIM is the inevitable and necessary direction for the future development of medicine. In this article, we illustrated the connotation of HIM, the differences between HIM and other medical conceptions, and the practice of HIM in recent years.

《环境科学与工程前沿（英文）》 2015年 第9卷 第2期   页码 230-239 doi: 10.1007/s11783-014-0651-3

摘要： Under both pyrolysis and combustion condition, HCl removal efficiency for medical waste with Ca-based additives was semi-quantitatively studied by means of TG-FTIR. Additionally, the difference of HCl removal efficiency for PVC and medical waste was compared. Experimental results showed that: 1) Thermal degradation of medical waste mainly took place in two steps under both pyrolysis and combustion condition; 2) HCl emitted at both two steps and HCl concentration increased with the increased of Cl ratio in the medical waste; 3) for the same additive, HCl concentration decreased with the increased of additives amount, that is to say, HCl removal efficiency of medical waste increased as the increased of Ca/Cl molar ratio. Fourth, when Ca(OH) was used as additive, HCl removal efficiency for medical waste combustion was a little higher than that for medical waste pyrolysis, but either CaCO or CaO was used as additive, it was just opposite, more specifically, when CaCO was used as additive with Ca/Cl=1.3, HCl removal efficiency was 5.49% under pyrolysis condition, but that was only 4.24% under combustion condition. Fifth, under the same Ca/Cl molar ratio, HCl removal efficiency for PVC was higher than that for medical waste under both pyrolysis and combustion condition, more specifically, when Ca(OH) was used as additive with Ca/Cl=1, HCl removal efficiency was 64.51% for PVC, but that was only 27.66% for medical waste pyrolysis with 4% Cl under pyrolysis condition.

摘要：

China recently instituted a two-child policy in response to its aging population, declining workforce and demographic dividend, and the need to develop asocial economy. Additionally, women generally delay having a second child because of the overwhelming pressure in their lives. With the improvements in assisted fertility technologies in recent years, the number of elderly women attempting to bear children has increased. The quality of woman’s eggs and a man’s sperm declined dramatically with increasing age, leading to an increased risk of pregnancy-related complications among older women. Therefore, the types of fertility problems experienced by elderly females must be provided with considerable attention by obstetricians. This commentary article focuses on the medical problems faced by older second-child pregnant women. This work discusses their increased rates of infertility, spontaneous abortion, fetal malformation, gestational diabetes, cesarean section, placenta previa, postpartum hemorrhage, postpartum depression, and hypertensive disorders, which complicate pregnancy.
