Dynamic model analysis of hydraulic support

In view of the shortcomings of traditional hydraulic support system, such as poor mobility and limited range of adjustment, a new configuration with double parallelogram structure is proposed. Combining the kinematic diagram of the mechanism of the new support system and the relevant parameters of the balance moment, using the kinematic vector closed-loop modeling method and D’Alembert’s principle, the relationship equation between the generalized coordinates of the hydraulic support and the geometric position parameters is obtained, and the analysis model with plural-freedom is established. Dynamic response characteristics and natural frequencies of column hydraulic cylinder and balance hydraulic cylinder are analyzed. The results demonstrate that the natural frequencies of the improved balance hydraulic cylinder and column hydraulic cylinder have been greatly improved, and the safety performance of the hydraulic support has been greatly increased.

Clinical practice of Chinese medicine navel therapy for chronic diarrhea: A literature review.

Chronic diarrhea is one of the most common complaints in clinical practice for both adults and children. The purpose of this study was to assess the commonly used Chinese herbal medicine navel therapy for the treatment of chronic diarrhea (traditional Chinese medicine syndrome of spleen deficiency). The literature search was up to June 2018. Four types of studies (clinical trials, case series, case reports, and experts' experience) researched on Chinese medicine navel therapy used alone or combined with other therapies for the treatment of chronic diarrhea all included. Information on prescriptions, effectiveness, and safety of intervention was collected. Traditional Chinese Medicine Inheritance Support System V2.5 was used to do data analysis. We included 416 studies. All these studies carried out in 194 cities of China. We obtained the most commonly used single herbs, herbal medicine combination, and Chinese patent medicine for both adults and children. The top 3 single herbs were Caryophylli Flos (Dingxiang), Cinnamomi Cortex (Rougui), and Euodiae Fructus (Wuzhuyu). The most frequently used Chinese patent medicines were Ding Gui Infantile Navel Paste and Huoxiang Zhengqi Liquid. The effectiveness assessment was based on clinical trials, but we did not perform a meta-analysis because of different study design and unsatisfactory methodological quality. No serious adverse reaction happened in original studies. The application of Chinese medicine navel therapy could be one of the ideal treatments for chronic diarrhea in the future, especially for children. However, high-quality studies are very needed to provide clear evidence.

Household structure and living arrangements among older persons in selected West Africa Countries: evidence from demographic and health surveys

Background: Older persons’ living arrangements are currently major development discourses across Africa. With the increasing family nucleation, weakening traditional ties and support networks, what is the emerging pattern of living arrangements of the older persons within this changing social system in West Africa? Methods: The study utilized DHS household data on older persons aged 60 years and above in selected West African countries: Benin Republic, Cote d’Ivoire, Ghana, Niger, Nigeria, Senegal and Togo (n=31,695). Results: Results showed that West African older persons had an average of 5.0 household network members; proportion living alone were higher among women (21.6%) than men (10.4%), majorly widows (31.3%) or single/divorced (38.0%). Household network, headship and living arrangements varied significantly across countries by age, sex, education, marital status and wealth quintile (p<0.05). Conclusion: The study concludes that the emerging pattern of older persons living alone is relatively high, suggesting age-friendly re-assessment of the traditional support system and household resources allocation.

Study on relevance mining of "core drug action target" in Dictionary of Traditional Chinese Medicine Prescriptions

Based on the database of "Dictionary of Traditional Chinese Medicine Prescriptions", high-frequency herbs of Xiaoke disease is mined by traditional Chinese medicine inheritance support system, and core herbs and combinations are discovered through association rules and cluster analysis. On this basis, based on the integrative pharmacology of traditional Chinese medicine to explore the herb-disease relationship, the "herb-compound-target" network is constructed and enriched for the analysis of key target gene functions, metabolic pathways, and their "core herb-target interactions". In order to explore the molecular mechanism of its prevention and treatment of diabetes, 341 diabetes prescriptions are collected, organized, and tapped in the Dictionary of Traditional Chinese Medicine Prescriptions. Herb frequency statistics show that Licorice was the most commonly used, followed by Ophiopogonis Radix, Poria, Ginseng Radix et Rhizoma, Coptidis Rhizoma, etc., the medicinal properties are mostly cold, warm and ping, and the medicinal taste tends to be pungent, bitter, and sour, and they were attributed to lung meridian, stomach meridian, spleen meridian, etc. Among them, the 17 herbs were closely related. Ginseng Radix et Rhizoma, Ophiopogonis Radix, Poria and Glycyrrhizae Radix et Rhizoma were the core Chinese herbs. Ophiopogonis Radix was the key node of Coptidis Rhizoma, Trichosanthis Radix and core Chinese medicine, and Ophiopogonis Radix was the key node for the connection between Coptidis Rhizoma and Trichosanthis Radix and the core Chinese herbs. Using integrated pharmacology platform analysis, 10 crucial core targets for the prevention and treatment of diabetes were obtained, including the known disease targets (PLCD1, PIK3R1, ENPP1), and potential herb targets(GNB1, ADCY1, AKT1, RAC1, PRKAA1, RHOA) , common target (GCK). There were seven similar targets in the 10 crucial core targets predicted with the combination of "Ophiopogonis Radix, Coptidis Rhizoma and Trichosanthis Radix", including PLCD1, PIK3R1, ENPP1, ADCY1, AKT1, PRKAA1, GCK. These genes were mainly located in the cytosol, plasma membrane, etc., involved in adenosine triphosphate binding, protein binding, platelet activation, etc., mainly involved in the endocrine system, signal transduction, chemokine signaling pathway, cancer pathway, and other metabolic pathways, and it is speculated that these genes were potentially associated with diabetes. In this study, Traditional Chinese Medicine Inheritance Support System and Integrative Pharmacology of Traditional Chinese Medicine are used to analyze the prescription law of Xiaoke prescription, and the correlation of "core herbs-functionary targets" is excavated, which provided the basis and reference for the screening and development of TCM prescriptions for the prevention and treatment of diabetes.

Analysis of traditional Chinese medicine prescriptions based on support vector machine and analytic hierarchy process

Combined use of drugs is a hot spot in the research of new drugs nowadays, and traditional Chinese medicine (TCM) is a classic practice in the combined use of drugs. In this paper, the compatibility of TCM prescriptions and the related properties of composed herbs were calculated and studied to verify and discuss the feasibility of the results in guiding compatibility. Research Group on New Drug Design, Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences had established a structured database of TCM prescriptions by using traditional Chinese medicine inheritance support system (TCMISS V2.0), including 4 012 prescription compatibilities, 2 072 drug components, 381 kinds of TCM diseases, 316 kinds of TCM syndromes and 26 kinds of drug properties. On the basis of the created database above, Support Vector Machine (SVM) was used to analyze the prescription compatibility data and establish a model for predicting feasibility of drug compatibilities. Analytic Hierarchy Process (AHP) and cluster analysis were used to study the influence of drug properties in the rationality of prescription compatibility. The computational results showed that the accuracy in efficacy prediction of two data sets, i.e. prescription-disease and prescription-syndrome, was up to 90% in the linear SVM model. The macro₋averaging and micro₋averaging of the two models were around 0.92, 0.46, respectively. After AHP mapping, most of the incompatible combinations showed significant difference with other drug combinations during the clustering process in the vertical icicle, indicating that the proper machine learning algorithm can be used to lay the foundation for further exploring the combination rules in TCM and establishing more detailed drug-disease and syndrome predicting models, and provide theoretical guidance for the study of the combined use of drugs to a certain degree.

Research of the BWS system for lower extremity rehabilitation robot.

Body weight support (BWS) system is increasingly used in conjunction with treadmills to assist the patients with neurological impairments. Owing to lower limbs of the patients unable to bear the whole weight during the rehabilitation training, some weight can be removed to help the patients recover the basic walking ability gradually. Therefore, considering the man-machine relationship and the effects of the rehabilitation, a wire-driven BWS system is designed. The main unit of the system is an active closed-loop controlled drive to generate the exact desired force. The force acted on the body is through the adjustment of the length of the rope which is connected to the harness worn by the patient. The structure designed in the research is easy to operate to realize the goal of the rehabilitation. To verify the effectiveness and practicability of the BWS system, some experiments have been curried out. From the results, not only the constant unloading force can be realized, but also the response time is limited in a small range which can bring a positive effect on correcting gait, improving balance and reducing muscle spasms. Also, compared to the traditional body weight support system, such as static system or passive elastic system, it has the advantages of the fast response, small errors and constant unloading force.

Totally, 545 prescriptions used for palpitation were included in this study and involved 247 Chinese herbs. The analysis results showed that the herbs in prescriptions for palpitation mostly had the warm property, and the herbs in heart and spleen meridian accounted for a larger proportion, indicating that the treatment was mainly to nourish heart and strengthen spleen. The top 11 herbs in usage frequency were consistent with the high-frequency medicines in medication patterns of common herbal pairs; therefore, we considered that these 11 herbs were the core herbs; the core herbal combination included Cassia Twig, Licorice, fossil fragments, Ostreae decoction, and evolved into 9 new prescriptions for treating palpitation. Our results objectively presented the prescription and medication rules for treating palpitation and provided extremely effective guidance for the clinical therapy.

Analysis of Chinese patent medicine prescriptions for Qi stagnation and blood stasis syndrome

To analyze the medication characteristics and compatibility rules in treatment of Qi stagnation and blood stasis syndrome. Chinese patent medicine prescriptions for Qi stagnation and blood stasis were collected from the 2015 edition of Pharmacopoeia of the people's Republic of China(herein after referred to as Chinese Pharmacopoeia) and Drug Standards of the People's Republic of China Ministry of Public Health-Chinese Patent Drug(herein after referred to as Chinese Patent Drug). Traditional Chinese medicine inheritance support system(TCMISS V2.5) was used to analyze the rules of prescription composition. Seventy-nine prescriptions included 105 symptoms, and dysmenorrhea, palpitations, chest tightness, stomach pain were common symptoms of Qi stagnation and blood stasis syndrome. Among 221 herbs, Chuanxiong Rhizoma, Salviae Miltiorrhizae Radix et Rhizoma and Angelicae Sinenses Radix ranked top 3 in usage frequency for the treatment of Qi stagnation and blood stasis. The herbal combinations included Angelicae Sinenses Radix-Chuanxiong Rhizoma, Salviae Miltiorrhizae Radix et Rhizoma-Carthami Flos, Chuanxiong Rhizoma-Carthami Flos, and Carthami Flos-Chuanxiong Rhizoma-Paeoniae Radix Rubra-Salviae Miltiorrhizae Radix et Rhizoma-Angelicae Sinenses Radix-Cyperi Rhizoma-Corydalis Rhizoma was the core herbal combination. In addition, a new prescription(Foenoculi Fructus-Alpiniae Officinarum Rhizoma-Caryophylli Flos-Angelicae Sinenses Radix-Chuanxiong Rhizoma-Leonuri Herba) for Qi stagnation and blood stasis syndrome was formed. Overall, the main symptom for the Qi stagnation and blood stasis syndrome could be pain, but because of different pathogenic factors, it could be reflected by different symptoms. Accordingly, invigorating the circulation of Qi and blood is the basic treatment for the Qi stagnation and blood stasis. Meanwhile, the treatment based on differentiation of symptoms and signs for different reasons should be considered. The prescriptions mainly included the herbs that could invigorate the circulation of Qi and blood, and were accompanied by the herbs that could warm spleen and stomach for dispelling cold.

Analysis on composition principles of prescriptions for nausea by using traditional Chinese medicine inheritance support system

Nausea is special in the symptoms, and is different from hiccups and vomiting. The main symptom is that the patients throw up the indigested food from the stomach regularly--if the patients have a dinner, they will throw out it in the next morning, or if the patients have a breakfast, they will throw out it at night. Nausea is common in clinic, and different physicians may use different treatment methods for it. This disease also cannot be treated efficiently and may happen repeatedly with the western medicine. In this study, the composition principles of prescriptions in past traditional Chinese medicine for nausea were analyzed and summarized by using traditional Chinese medicine inheritance support system(V2.5), hoping to provide guidance for clinical drug use and summarize the basic rules for treatment of nausea.The prescriptions for nausea in "the prescription of traditional Chinese medicine dictionary" were selected, and the information was entered into the traditional Chinese medicine inheritance support system(TCMISS) to build a database. Data mining methods such as frequency statistics, association rules, complex system entropy clustering were used to analyze and summarize the composition principles of these prescriptions. The herb frequencies of the prescriptions were finally determined; herbs with higher use frequencies were obtained; and the association rules between herbs were found. 19 commonly used herb pairs, 10 core combinations and 10 newly developed prescriptions were found. The basic pathogenesis of nausea in traditional Chinese medicine is the weakness and coldness of spleen and stomach, and the Qi adverseness of stomach. Generations of physicians' main therapeutic method for nausea is mainly to warm the middle and invigorate the spleen, lower Qi and regulate stomach. The commonly used herbs for nausea are ginger, ginseng, large head attractylodes, tuckahoe, licorice, and appropriately supplemented with the herbs of eliminating dampness and eliminating phlegm, and regulating Qi-flowing for harmonizing stomach. In addition, it shall be treated according to the different accompanying syndromes such as phlegm, blood stasis, and yin deficiency.
