RESUMO

Obtaining lignin-based graphite-like microcrystallites at a relatively low carbonization temperature is still very challenging. In this work, we report a new method based on condensed structures, for regulating graphite-like microcrystalline structures via the incorporation of 4,4'-diphenylmethane diisocyanate (MDI) into the main structure of lignin. The effects of MDI on the thermal properties of lignin and the graphite-like microcrystalline structure of lignin-based ultrafine carbon fibers were extensively studied and investigated. The incorporation of MDI decreased the thermal stability of lignin, increased the carbon yield and enhanced the formation of graphite-like microcrystallites, which are beneficial for reducing energy consumption during the preparation of lignin-based carbon fibers. The modified lignin-based ultrafine carbon fibers (M-LCFs) demonstrated satisfactory electrochemical performance, including high specific capacitance, low charge transfer resistance, and good cycle performance. The M-LCFs-3/2 electrode had a specific capacitance of 241.3 F g-1 at a current density of 0.5 A g-1, and a residual ratio of 90.2 % after 2000 charge and discharge cycles. This study provides a new approach to control the graphite-like microcrystalline structure and electrochemical performance while also optimizing the temperature.

RESUMO

Renying Cunkou pulse method is one of the classical pulse methods of acupuncture-moxibustion in the Yellow Emperor's Inner Canon, which is also a classical clinical paradigm for diagnosing and treating meridian diseases in the ancient times. Based on comprehensive review of literature and clinical practice, this paper reveals that this method compares the size of the neck Renying pulse with hand Cunkou pulse to determine the change of yin-yang and excess-deficiency identifying the affected meridians. The jing-well, xing-spring, and shu-stream points of the surface and interior meridians of affected meridians are mainly selected to regulate deficiency and excess through reinforcing and reducing methods. The Renying Cunkou pulse method possesses a simple and practical medical theory, easy diagnostic procedure, and clear meridian selection for acupuncture-moxibustion treatment, warranting further exploration of its essence and diagnostic therapeutic principles.

RESUMO

Mueller matrix (MM) polarimetry can provide comprehensive information about the polarization properties that are closely related to the microstructural features and has demonstrated its potential in biomedical studies and clinical practices, and bright-field microscopy is widely used in pathological diagnosis as the golden standard. In this work, we improve the throughput of MM microscopy by learning a statistical transformation between these two imaging systems based on deep learning. Using this approach, the MM microscope can generate an image that is equivalent to a bright-field microscope image of the matching field of view. We add new transformative capability to the existing MM imaging system without requiring extra hardware. The translation model is based on conditional generative adversarial network with customized loss functions. We demonstrated the effectiveness of our approach on liver and breast tissues and evaluated the performance by four quantitative similarity assessment methods in pixel, image and distribution levels, respectively.

RESUMO

Regarding the existing questions of the understanding and application of lateral needling technique in the Chapter 7 of Lingshu (Miraculous Pivot), after analyzing the original meaning of the lateral needling technique and its indication for "tendon bi syndrome" in literature, it is believed that lateral needling technique is the classic manipulation for tendon bi syndrome, mainly for tendon spasticity caused by obstruction of qi activity or retarded qi activity. The filiform needle is used in the operation. The puncture hand and the pressing hand should be cooperated during the manipulation, in which, after detecting the location of tendon disorder by the pressing hand, the needle is inserted from the lateral side of the affected site and is manipulated with the reinforcing technique achieved by lifting and thrusting needle. Afterwards, the needle is withdrawn. The lateral needling technique of acupuncture is one of the mass-loosening techniques in Neijing (Inner Classic). It is a reliable technique of acupuncture in clinical treatment of acute and chronic diseases, such as cervical spondylosis and tendon injury of lumber region and has a stable therapeutic effect.

RESUMO

The even reinforcing-reducing technique of acupuncture is one of the common needling methods in clinical practice at present, but there are various understandings on it among scholars. In the paper, the origin of the even reinforcing-reducing technique of acupuncture was explored on the base of literature collection and clinical practice. The comments were put forward in association with the initial understanding of reinforcing and reducing techniques of acupunctures and actual clinical applications. In ancient time, the even reinforcing-reducing method includes two meanings. The first one refers to the compound reinforcing-reducing needling technique for mixture of cold and heat or of deficiency and excess, in which, the reinforcing and reducing techniques are used alternatively at same acupoint. The second one implies the imbalance of yin and yang with human body or meridian involved. For example, in the syndromes as excess in the upper part of body and deficiency in the lower part, heat on the left and cold on the right, the treatment for reinforcing the lower and reducing the upper, or reinforcing the right and reducing the left is adopted to rebalance yin and yang. Hence, it is regarded as a treating principle or a needling method. No matter at the same acupoint or at different acupoints, the final target of treatment is to harmonize yin and yang. The acupuncture scholars in modern times seldom describe even reinforcing-reducing technique. Since the foundation of People's Republic of China, the relevant technique is again called even reinforcing-reducing manipulation, characterized as evenly lifting, thrusting and rotating of needle and has been developed gradually as the common needling technique in present clinical practice, which is widely divergent from the traditional understanding. The reinforcing-reducing techniques of acupuncture are different in understanding between the ancient time and the present. It is necessary to identify the origin for the better contributions to clinical application.

RESUMO

Through the collection of Practice of acupuncture and moxibustion written by CHEN Jingwen, the acupuncture master in the Republic of China, the academic characteristics on acupuncture and moxibusiton were analyzed. The literature comparison method was adopted to compare the works of LUO Zhaoju, ZENG Tianzhi and LI Wenxian, etc. at the same period. It was discovered that CHEN Jingwen was the medical master who systematicly brought up the theory of acupoint properties earlier in the modern times. Classifying drugs based on acupoints was his academic feature. Additionally, the compatibility therapy of Chinese medicine was introduced to explain the essential ideas on the acupoints combination. The treatment was determined on the basis of zangxiang theory and the reinforcing and reducing therapy of acupuncture was emphasized in the determination of treatment and prescription. CHEN Jingwen's theory of acupoint property had been stressed and spread among the medical scholars in the Republic of China and he had made the beneficial exploration for the development of modern acupuncture and moxibustion therapy.

RESUMO

In addition to the collected books in the General Catalog of Ancient Chinese Medical Books, there are lots of acu-moxibustion literature of the Republic of China period scattered among the people which are not carried in this Catalog, some of them are rare and precious ones. In 1933, the first issue of Acu-moxibustion Journal was published and became the first professional Journal of acupuncture and moxibustion in China, 35 issues were published at that time, with many monographs on acu-moxibustion carried in its "special column". Meanwhile, other acupuncturists from different regions also established acu-moxibustion associations or schools and edited all kinds of acupuncture moxibustion teaching materials in order to develop acu-moxibustion education. In a word, the acu-moxibustion literature of the Republic of China were not only rich in forms and contents, but also combined with regional characteristics. Therefore, it should be pay more attention on that field and do further study.
