Since the beginning of the Western Learning, modern medicine has developed rapidly in China, and the integration of Chinese and western medicine has become inevitable. Since Zhang Xichun’s 'Medicine in the West', using traditional Chinese medicine theory to guide the practice of western medicine, through long-term clinical diagnosis, we gradually realized the advantages of applying western medicine according to TCM syndrome differentiation. Therefore, 278 patients from the Second People’s Hospital of Gansu Province from July 2015 to December 2017 were enrolled in the relevant departments of the Department of Internal Medicine. On the basis of routine treatment, TCM was obtained through inspection, inquiry, listening and smelling, palpation and pulse-taking. The syndrome type is based on the medicinal properties, menstruation and ef?cacy of more than ten kinds of western medicines, so that they can reach Chinese medicine(1)Therefore, this paper aims to improve the accuracy of western medicine use, reduce the incidence of adverse reactions, discover the new ef?cacy of western medicine,and promote the integration of Chinese and western medicine. 展开更多

The history of medical development shows that oriental medicine, or traditional medicine, was born through medical practice during the times when science and technology were immature and underdeveloped, whereas with the development of science and technology, Western medicine, or modern medicine, was born through experimental analysis and research. With the development of medicine, the pros and cons of both medical systems become increasingly evident. How to integrate them and learn from each other will be the direction of future development of medicine. The formation and development of integrated medicine will, inevitably, usher in a new era for medicine. 展开更多

At present, colorectal cancer depends on surgery, radiotherapy and chemotherapy. Due to the characteristics of the elderly, postoperative recovery is slow, prone to postoperative complications and difficult to tolerate radiotherapy and chemotherapy have become the main problem hindering the disease. Based on the theory of prevention, the use of drugs from the perspective of constitution and etiology can prevent the occurrence of colorectal cancer in the elderly. Traditional Chinese medicine (TCM) combined with radiotherapy and chemotherapy can alleviate adverse reactions and improve treatment efficacy. TCM with surgical treatment can reduce the occurrence of postoperative complications and promote postoperative recovery. For patients with advanced colorectal cancer, TCM can play a role in fighting cancer and improving the quality of life of patients. For patients in stable phase, TCM can prevent tumor recurrence and metastasis. 展开更多

Labrasol, as a non-ionic surfactant, can enhance the permeation and absorption of drugs, and is extensively used in topical, transdermal, and oral pharmaceutical preparations as an emulsifier and absorption enhancer. Recent studies in our laboratory have indicated that labrasol has a strong absorption enhancing effect on different types of drugs in vitro and in vivo. This study was performed to further elucidate the action mechanism of labrasol on the corneal penetration. In this research, the fluorescein sodium, a marker of passive paracellular transport of tight junction, was selected as the model drug to assess the effect of labrasol on in vitro corneal permeability. To investigate the continuous and real-time influence of labrasol on the membrane permeability and integrity, the Ussing chamber system was applied to monitor the electrophysiological parameters. And, furthermore, we elucidated the effect of labrasol on excised cornea at the molecular level by application of RT-PCR, Western blot, and immunohistochemical staining. The results indicated that labrasol obviously enhance the transcorneal permeability of fluorescein sodium, and the enhancement was realized by interacting with and down-regulating the associated proteins, such as Factin, claudin-1 and β-catenin, which were contributed to cell-cell connections, respectively. 展开更多

Traditional rural homegarden agroforestry systems(referred to as homegarden) in the Western Sichuan Plain of China are often referred to as 'Linpan' in Chinese. These homegardens are usually composed of farm houses, trees, bamboos, and small patches of land for flowers, fruits and vegetables. Over the Western Sichuan Plain’s area of approximately 18,800 km2, there were more than 200,000 homegardens, accommodating 72.5% of the region’s rural population. As a unique local, cultural, and ecological resource, homegardens continuously support peasant households with provisioning, regulation, and landscape ecosystem services. This study combined low height remote sensing used unmanned aerial vehicle(UAV) photography, field investigation, and instrument monitoring. We try to identify the composition and structural characteristics of homegardens, as well as climatic regulation effects of the different types of homegardens. Temperature data were collected both for summer(June to August 2016) and winter(December 2016 to February 2017). The result shows that:(1) the average area of homegardens was 0.67 ha(sizes ranging from 0.16 ha to 1.24 ha), and with vegetation coverage 43.5%-76.9%(including 310 plant species).(2)In comparision with outside the homegardens, the average temperature inside the homegardens was significantly lower in summer(approximately 0.31 ℃-0.90 ℃). Although, the lowest summer temperature was differentiatee in between 13:30-16:00. Especially, the thermal effects of the home gardens were ranged from 2.00℃-2.65℃ at high temperatures(≥30℃).(3) The cooling effect of homegardens were positively correlated(p<0.05) with tree area(X1), vegetation coverage(X2), tree coverage(X3), tree species(X4), and tree biomassper unit area(X5), and the contribution rate was represented by X3>X4>X5>X2>X1.(4)This study indicates the major role of homegardens for climate regulation and energy efficiency, providing suggestions for homegarden transformation and construction planning for new rural communities. 展开更多

Health medicine has been the direction of the development of medicine. However, the definition of health defined by Western medicine and traditional medicine cannot completely cover the ful meaning of health. Therefore, we propose the new concept of health: health is a state of physical and mental harmony of different individuals in the life process with the environment, and good self-adaptive and regulation ability to natural and social environment. The new concept of health enriches the connotation of health defined by Western medicine and improves the understanding of health in the past, which provide the conceptual basis for further study on health medicine. 展开更多

Choledochal cysts(CCs)are rare bile duct dilatations,intra-and/or extrahepatic,and have higher prevalence in the Asian population compared to Western populations.Most of the current literature on CC disease originates from Asia where these entities are most prevalent.They are thought to arise from an anomalous pancreaticobiliary junction,which are congenital anomalies between pancreatic and bile ducts.Some similarities in presentation between Eastern and Western patients exist such as female predominance,however,contemporary studies suggest that Asian patients may be more symptomatic on presentation.Even though CC disease presents with an increased malignant risk reported to be more than 10%after the second decade of life in Asian patients,this risk may be overstated in Western populations.Despite this difference in cancer risk,management guidelines for all patients with CC are based predominantly on observations reported from Asia where it is recommended that all CCs should be excised out of concern for the presence or development of biliary tract cancer. 展开更多

HIV-indeterminate Western blotting(WB)results are typically obtained in WB confirmatory assays,and the number of indeterminate samples may increase with the detection of HIV infections,which will present considerable challenges for the management of HIV/AIDS.Nucleic acid detection has been used as a laboratory test for screening suspected or indeterminate samples.However,the effectiveness of these assays for the differential diagnosis of HIV-indeterminate WB samples remained undetermined.In this study,210 subjects with HIV-indeterminate WB results were detected from 6360 positive HIV screening samples between 2015 and 2016 in southeastern China,in which HIV-indeterminate WB results accounted for 3.30%.The highest proportion of indeterminate results was observed in pregnant and lying-in women receiving physical examinations(16.67%),followed by that in voluntary blood donors(8.82%).The most common WB band patterns were p24,gpl60 and p24,and gpl60.The follow-up study revealed that the highest negative and positive conversion rates of HIV antibodies were in samples with a single p24 band(80.28%),and with gpl60 and p24 bands(86.21%),respectively.Among the Env,Gag,and Pol antibodies,samples with a Gag band showed the highest negative conversion rate(81.25%),whereas the highest positive conversion rate was observed in samples with an Env band(56.76%).In addition,quantitative and qualitative HIV nucleic acid testing exhibited the highest sensitivity(96.3%)and specificity(97.85%),respectively.Our results indicate a lower proportion of HIV indeterminate WB results in southeastern China compared to previous reports,and the follow-up re-examination of patients with HIV indeterminate results should be performed.Nucleic acid testing facilitates the identification of HIV infections. 展开更多

The western Kunlun orogen in the northwest Tibet Plateau is related to subduction and collision of Proto-and Paleo-Tethys from early Paleozoic to early Mesozoic.This paper presents new LA-ICPMS zircon U-Pb ages and Lu-Hf isotopes,whole-rock major and trace elements,and Sr–Nd isotopes of two Ordovician granitoid plutons(466–455 Ma)and their Silurian mafic dikes(~436 Ma)in the western Kunlun orogen.These granitoids show peraluminous high-K calc-alkaline characteristics,with(87Sr/86Sr)i value of 0.7129–0.7224,εNd(t)values of-9.3 to-7.0 and zirconεHf(t)values of-17.3 to-0.2,indicating that they were formed by partial melting of ancient lower-crust(metaigneous rocks mixed with metasedimentary rocks)with some mantle materials in response to subduction of the Proto-Tethyan Ocean and following collision.The Silurian mafic dikes were considered to have been derived from a low degree of partial melting of primary mafic magma.These mafic dikes show initial 87Sr/86Sr ratios of 0.7101–0.7152 andεNd(t)values of-3.8 to-3.4 and zirconεHf(t)values of-8.8 to-4.9,indicating that they were derived from enriched mantle in response to post-collisional slab break-off.Combined with regional geology,our new data provide valuable insight into late evolution of the Proto-Tethys. 展开更多
