Huanglian is a commonly used Chinese medicinal herb in the ancient and the present. It has a history of 2000 years in clinical application, having the efficacy of "Clear away heat and remove dampness, purge the sthenic fire and eliminate toxic materials", therefore can be used for various diseases or syndromes in types of dampness-heat and fire-toxin by internal or external use. Compound prescriptions mainly based on Huanglian or prescribed by Huanglian, such as Puji Xiaodu Yin, Huanglian Jiedu Tang, Zhusha Anshen Wan, Qingying Tang, Angong Niuhuang Wan, Niuhuang Qingxin Wan, Jiaotai Wan, Huanglian Ejiao Tang, Zuojin Wan, Danggui Longhui Wan, Huanglian Yanggan Wan, Wu Xiexin Tang, Lianpu Yin, Gegen Huangqin Huanglian Tang, Baitouweng Tang, Xianglian Wan etc. All of these are well-known formulas for clearing away toxin of heat-fire of heart and liver, as well as dampness-heat of stomach and intestines. Nowadays, Huanglian is generally considered as a kind of antibiotic and antivirus herb and is widely used for many infective diseases. In fact, it is also used to cure cardiovascular and cerebrovascular diseases, diabetes and cancer based on pharmacological studies. Having been using Huanglian in treating the above diseases and having conducted clinical and experimental research on cancer and liver diseases, the author observed that Huanglian and its compound prescriptions have obvious effects on liver diseases such as acute or chronic hepatitis, liver fibrosis, liver cirrhosis and liver cancer due to types of dampness-heat and fire-toxin. Part of the effects has been proved by experimental research and it is worth carrying out more research in this area for development and clinical application.

Objective To investigate the value of double contrast-enhanced ultrasonography (DCEUS) in combination with three-dimension (3D) contrast-enhanced ultrasound in diagnosis of benign or malignant gastric ulceration. Methods A total of 47 patients with gastric lesions were enrolled in this study. All have the pathological results, 22 of them were benign ulceration and 25 were malignant. All patients underwent DCEUS and 3D contrast-enhanced ultrasound. On the basis of oral contrast-enhanced ultrasound agents, intravenous contrast-enhanced ultrasound agents were given at the same time. Images and data were recorded. The arrival time (AT), time to peak (TTP), infusion time (IT), baseline intensity (BI), peak intensity (PI) and enhanced intensity (EI) were calculated using the time-intensity curve (TIC). Results All benign ulcerations were imaged as small pits with slight thicken of gastric wall [(8.66±2.87) mm] using DCEUS,while malignant lesions were relatively large irregular-shape, unevenly-bottom pits with significant thicken of gastric wall [(13.98±3.63)~(20.83±3.69) mm]. 3D-DCEUS images were analyzed for gastric mucosal folds, ulceration lesions, as well as local vascularity. All ulceration lesions showed broken of gastric mucosal folds, and malignant lesion showed thickness of gastric wall as“crater”, with rich and irregular vascularity. There were no statistical differences between benign gastric ulcerations and adjacent normal gastric wall (P>0.05). Malignant gastric ulceration were compared with adjacent normal gastric wall tissue, TTP, IT and BI had no statistical differences (P>0.05), while AT, PI, and EI had statistical differences [(9.00±2.02) s vs (10.90±2.75) s, P=0.008], [(35.46±5.77) dB vs (29.73±8.72) dB, P=0.009] and [(30.76±5.76) dB vs (23.45±6.84) dB, P=0.000]. PI and EI in malignant tumors were higher than those in benign ones (P<0.05). Conclusion DCEUS could be a new method in differentiating benign and malignant gastric ulceration, which can get both the anatomy and perfusion information of gastric wall as well as lesions. 3D-DCEUS can improve the quality of the conventional ultrasound image.

OBJECTIVETo study on the reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in total knee arthroplasty (TKA) the rotational alignment reference bony landmarks of the proximal tibial component on magnetic resonance image (MRI) were measured.

METHODSFrom January 2010 to December 2013, 80 normal knees of Chinese volunteers including 35 males and 45 females with an average age of (35.4±6.1) years were reviewed. The images of the knees were obtained by MRI. The surgical epicondylar axis (STEA) was identified in the femoral transverse sections and then was projected to the side of tibia, forming the SETA'. A line connecting the medial border of the patellar tendon and the middle of the posterior cruciate ligament insertion (Akagi line) and its vertical line (AK), as well as a line connecting the medial 1/3 of the patellar tendon and the middle of the posterior cruciate ligament insertion and its vertical line (AP), were identified in the tibial transverse sections. The angles were measured between the AK, AP and STEA'.

RESULTSThe angle between AK and STEA' was (0.59±2.07)°, and there was no significant difference between the two lines (t=-2.54, P=0.13). The mean angle between AP and STEA' was (3.21±2.04)°, and there was a significant difference between the two lines (t=14.05, P<0.05). There was a significant difference between the AK and AP (t=-11.68, P<0.05).

CONCLUSIONThe reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in TKA is good.

Polysaccharides from Chinese medicines are attracting increasing attention to their wide range of valuable biological activities. As these polysaccharides are mostly from edible materials, their safety can be greatly ensured. Therefore, the Chinese medicine polysaccharides have been the focus of research and development of new drugs and health products. However, there are rarely successful cases. Here, based on the authors' own research experience, the difficulties and challenges in chemical analysis and mechanism study of Chinese medicine polysaccharides are discussed, in the hope of eliciting more innovative ideas and solutions.

ObjectiveTo develop a systematic review of physical activity benefits for children and adolescents with intellectual and developmental disabilities and the PICO framework based on the International Classification of Functioning, Disability and Health (ICF), and to explore the health benefits of physical activity for children and adolescents with intellectual and developmental disabilities. MethodsA systematic analysis of health and functional status, physical activity interventions, and physical activity benefits in children and adolescents with intellectual and developmental disabilities was conducted using ICF. Databases such as PubMed, Embase, Web of Scienc, and CNKI were searched to collect published randomized controlled trials on health and functional outcomes of physical activity participation in children and adolescents with intellectual and developmental disabilities from establishment to November, 2022 for a systematic review. ResultsTen randomized controlled trials from five countries were finally included, involving 289 participants (five to 18 years old). The literatures were mainly from the fields of cognitive neuroscience, intellectual and developmental disabilities, physical activity and exercise rehabilitation, and were published mainly after 2013. The quality of the included literatures was evaluated using the Physiotherapy Evidence Database (PEDro) scale with a mean score of 7.6. Health-related conditions in children and adolescents with intellectual and developmental disabilities included Down syndrome, dyskinetic cerebral palsy, autism spectrum disorders, fragile X syndrome, and patients with mild and moderate intellectual and developmental disabilities. Physical activity interventions for children and adolescents with intellectual and developmental disabilities were focused on schools, rehabilitation centers, gymnasiums, laboratories, and research institutions and were usually in the form of motor rehabilitation, physical activity and physical education programs. The physical fitness focused on vestibular stimulation training, inversion exercises and core muscle training; the sports events included soccer training, bicycle riding, etc. The frequency of physical activity was one to seven times per week, with moderate intensity and a duration of four weeks to 1.5 years. The health benefits of physical activity were divided into three levels. At the physical function level, physical activity could significantly improve the muscle strength and endurance, aerobic capacity, lower limb motor stability and balance, promote perceptual-motor coordination, reduce psychomotor error rates, and improve perceptual-motor function and overall motor execution. At the activity and behavioral health level, physical activity could significantly improve the concentration time in movement, improve single-leg stance time and core strength in the lumbar and abdominal areas to improve postural control and mobility, involving performance levels in activities such as lying and rolling, sitting, kneeling, standing, walking, running and jumping. At the quality of life and well-being level, physical activity intervention could increase their fun experiences and activity participation time, etc. ConclusionThe health conditions of children and adolescents with intellectual and developmental disabilities are mainly involved in Down syndrome, dyskinetic cerebral palsy, autism spectrum disorder, and fragile X chromosome. The physical activity intervention program is characterized by a predominantly physical activity program oriented and skill oriented. The health and functional benefits of physical activity participation in children and adolescents are mainly characterized by improved neuromusculoskeletal and motor-related functions, enhanced activity and participation levels, reduced sedentary behavior, increased participation in daily activities, and improved quality of life and well-being.

OBJECTIVETo assess the reliability, validity and responsiveness of the Chinese Quality of Life Instrument (ChQOL) in patients with chronic heart failure (CHF).

METHODSAssessment on quality of life (QOL) of 39 CHF patients was performed in synchronous step adopting three generally used questionnaires the World Health Organization Quality of Life Assessment (WHOQOL-BREF), the Medical Outcomes Study Short Form 36-items Health Survey (SF-36), and the Minnesota Living with Heart Failure Questionnaire (MLHF), as well as the ChQOL respectively.

RESULTSChQOL showed good internal consistency (Cronbach's alpha > 0.7), with its theoretical structural model consistent with the three factors produced from factor analysis, and showed better criterion validity than that of WHOQOL-BREF, SF-36 and MLHF. The 4 weeks' follow-up visiting completed in 32 patients showed that according to patients' self-evaluation and the cardiac functional assessment by the doctors, the responsiveness of the ChQOL was better than that of the WHOQOL-BREF and SF-36, but slightly inferior to that of the MLHF.

CONCLUSIONChQOL showed good reliability, validity and responsiveness in assessing QOL of CHF patients.

Objective To understand the correlation of enterovirus 71 (EV71), P-selectin glycoprotein ligand-1 (PSG L-1), and scavenger receptor B2 (SCARB2) and to explore the possible pathway and mechanismof EV71 infection by observing the expression of EV71, PSG L-1 and SCARB2 in tissues of infants with brain stemencephalitis. Methods T he organs and tissues of infants with EV71-VP1 positivi-ty in their brain stems were chosen. Expression and distribution of EV71-VP1, PSG L-1, and SCARB2 were detected and compared by immunohistochemistry. Results Strong staining of EV71-VP1 was ob-served in the neuron, glial cells, the inflammatory cells of perivascular cuffing, parietal cells of the gas-tric fundus gland while alveolar macrophages, intestinal gland epitheliumcells, mucosa lymphoid nodule and lymphocyte of palatine tonsil showed moderate staining and weak staining were displayed in mesen-teric lymph nodes and lymphocyte of spleen. PSG L-1 expression was detected in parietal cells of the gastric fundus gland, tonsillar crypt squamous epithelium, alveolar macrophages and leukocytes in each tissue. SCARB2 expression was observed in all the above tissues except the intestines and spleen. Con-clusion T he distribution of EV71 correlates with SCARB2 expression. SCARB2 plays an important role in virus infection and replication. Stomach may be an important site for EV71 replication.
