The Fragment of Dunhuang Ancient Tibetan Moxibustion Therapy contains rich content on fire moxibustion therapy of Tubo-period Tibetan medicine, characterized by distinctive clinical features of Tibetan acupuncture and strong regional attributes. This paper systematically reviews the relevant materials on moxibustion in the Fragment and summarizes the findings as follows: Tibetan fire moxibustion mainly uses mugwort as the material, and terms like "fine mugwort", "broad bean" and "sheep dung pellet" refer to the size of the moxa cone. The number of moxa cones used is predominantly odd numbers, usually ranging from 5 to 21. The main indications for fire moxibustion cover internal medicine, external medicine, gynecology, pediatrics, and various pain syndromes. The therapy advocates for treating acute conditions and heat syndromes with moxibustion. The manuscript also records detailed contraindications, including time-based and seasonal taboos. Moxibustion is applied to both local and distal acupoints, reflecting the therapeutic concept of treating both proximal and distal regions. Furthermore, it documents simple and practical acupoint localization methods such as surface anatomical markers, proportional bone measurement, finger measurement, and hand-span measurement. Compared with contemporaneous Chinese medical moxibustion techniques, the moxibustion methods recorded in this Fragment are rich in content and present unique Tibetan theoretical characteristics. It provides valuable data and evidence for the excavation, application, and further research of Tibetan acupuncture and moxibustion.

This paper summarized Professor ZHOU Zhongying's experience in differentiating and treating hepatitis and liver cirrhosis from deficiency and excess. It is considered that the pathogenesis of hepatitis and liver cirrhosis belongs to deficiency in root and excess in branch, with depletion of liver, spleen and kidney as the root, and constraint and bind of damp-heat and stasis toxin as the branch. Moreover, mutual cause and promotion between deficiency and excess leads to the disease. For general principle of treatment, it is recommended to clear and transform pathogenic excess, supplement deficiency and rectify the healthy qi. In the early stage of hepatitis and cirrhosis, excess pathogen hyperactivity is the main manifestation, which can be treated by clearing and transforming damp-heat and stasis toxin, supplemented by regulating spleen and stomach, with modified Yinchenhao Decoction (茵陈蒿汤) and Biejiajian Pill (鳖甲煎丸). In the middle and late stages, cases with deficiency-excess complex were more common, which should be treated by clearing damp-heat and stasis toxin, regulating and supplementing liver-spleen-kidney, using medicinals with the function of clearing heat and dispelling damp, dissolving stasis and resolving toxins to treat the branch. Moreover, Liujunzi Decoction (六君子汤), Yiguan Decoction (一贯煎)plus Erzhi Pill (二至丸) and Buzhong Yiqi Decoction (补中益气汤) modifications are suggested respectively in correspondence to the different kinds of root deficiency including irregular liver and spleen, liver and kidney yin deficiency, and liver-spleen-kidney deficiency.

Emaciation is a common physical condition in clinical practice,often accompanied by symptoms related to"excessive fire in thin people".Insufficient yin-qi is the main physiological and pathological basis of emaciation,and excessive dryness-heat is the secondary manifestation.The disease involves five viscera,with the spleen as the core.The principle of treatment is to nourish yin-qi as the main method,and to dissipate stagnant heat as the auxiliary method.Specifically,it includes two aspects:treating the root cause and treating the symptoms.Treating the root cause should nourish yin-qi to improve the"emaciation"constitution,and treating the symptoms should dissipate stagnant heat to eliminate the"excessive fire"state.The importance of the two should be determined ac-cording to the severity and urgency of the excessive fire.Clinically,the addition and subtraction of medicinal ingredients are made ac-cording to factors such as the urgency of the root cause and symptoms,the state of emaciation and the ability to eat,the degree of defi-ciency or excess of fire-heat,the pathogenesis of the disease,and the season.

Objective:To evaluate and compare the inpatient medical services of secondary public and private general hospitals by using disease risk adjustment model, and to explore the application of disease risk adjustment model in medical service evaluation of different ownership hospitals.Methods:Based on 1 032 865 front pages of medical records in Chengdu in 2017 and 2018, a regression model with mortality, average length of stay, total hospitalization expenses, medical service fees, drug costs and surgical consumables costs as dependent variables and related influencing factors as independent variables was established by using disease management intelligent analytic and evaluation system. The risk adjusted case mix index(ACMI) was calculated. The mortality, average length of stay, hospitalization expenses and other indicators were predicted. The ratio of observed value to expected value(O/E value) of each index in public and private secondary general hospitals was obtained and compared.Results:The ACMI value of secondary public general hospital was 4.63, slightly higher than that of private hospitals(4.55). The technical difficulty and resource consumption of the public hospitals were slightly higher than that of the private hospitals.From the O/E value, the management of disease mortality, medical service fees and inpatient drug costs of secondary public hospitals was generally good, and the O/E values of hospitalization expenses of each secondary private general hospital were quite different, and there was a possibility that the costs were unreasonable. The O/E value of surgical consumables cost in secondary public general hospital was 1.54, and there was room for improvement in cost management.Conclusions:The disease risk adjustment model fully considers the characteristics of different types and severity of diseases in different institutions, which can not be simply compared. Based on individual cases, it realizes the comparability of different ownership hospitals, and provides a new means for the evaluation of medical service ability and quality.

Objective:
To study new ways and tools for assessing the inpatient disease management and improving refined management of the hospital.
Methods:
By using homepages of medical records of the patients discharged from 21 tertiary general hospitals in a city in 2016, we completed the modeling and predicted value calculation within each DRGs with the Disease Management Intelligent Analytic & Evaluation System (DMIAES System).
Results:
2 192 predication models were built, to compute the theoretic values of the mortality rate, length of stay, medical fee, medical service fee, and drug cost of each inpatient. Such values were compared with the observed results to gain the O/E index. If O/E is less than 1, it indicates that the inpatient′s disease management is good and better than expected. On the other hand, O/E index greater than 1 indicates poorer disease management than expected and rooms of further improvement. With the help of O/E index, we made multidimensional comparisons assessment and analysis of different hospitals, clinical disciplines, diseases and doctors.
Conclusions
The DMIAES System can take risk factors of inpatients′ outcomes into account, assessing the major indicators of inpatient outcomes by means of big data and modelling. This approach proves effective in enabling administrators and doctors to rapidly analyze problems for identifying solutions and enhancing management, thus having great potential in hospital management, supervision and assessment.

Objective To explore the iodine nutritional status of all people after the practice of new standard of edible iodized salt, to assess whether the new standard of edible iodized salt can satisfy the iodine nutrition need in different populations, and to provide a scientific basis for supplementation of iodine. Methods Before and after the implementation of new salt iodine concentration, in 2009 and 2015, a contrastive study was performed in 1 243 people(including 402 children aged 8 to 10 years,408 adults aged 18 to 45 years,211 pregnant women and 222 lactating women) who lived in urban and rural areas of Wuwei City. Random urine samples were collected to measure the urinary iodine in all populations and household salt samples were collected. Urinary iodine was detected by arsenic cerium catalytic spectrophotometry(WS/T 107-2006).The iodine level in salt was determined by direct titration(GB/T 13025.7-2012).Results Before and after the implementation of new iodine salt standard, the coverage of adequately iodized salt was consistently higher than 94%, the qualified rate of iodized salt was consistently higher than 96%,the median of iodized salt was reduced from 31.0 mg/kg to 26.9 mg/kg;the medians of urinary iodine of children aged 8 to 10 years, adults, pregnant and breastfeeding women were reduced from 290.84, 225.52,200.42 and 180.65 μg/L to 187.37,174.96,159.99 and 152.88 μg/L;the ratios of urinary iodine which was less than 100 μg/L in children aged 8 to 10 years, adults and breastfeeding women were risen from 5.15% (10/194), 12.57% (24/191) and 16.19% (17/105) to 10.58% (22/208), 15.81% (34/215) and 33.33% (39/117); the ratio of urinary iodine which was less than 150 μg/L in pregnant women was risen from 39.78%(37/93)to 43.22%(51/118);the ratios of urinary iodine between 100 and 200 μg/L in children aged 8 to 10 years and adults were risen from 15.46% (30/194) and 30.37% (58/191) to 44.23% (92/208) and 43.26% (93/215); the ratios of urinary iodine greater than 300 μg/L in children aged 8 - 10, adults, pregnant and breastfeeding women were reduced from 47.94%(93/194),34.55%(66/191),29.76%(26/93)and 28.57% (30/105) to 17.31% (36/208), 19.07% (41/215), 16.95% (20/118) and 11.97% (14/117). Conclusion After the implementation of new salt iodine concentration standard,the iodine nutrition level has decreased in all groups and better suited for children aged 8 to 10 years and adults,but the risk of iodine deficiency is increased in pregnant and breastfeeding women.

Objective To explore the effect and safety of ice compress combined with early walking training on postoperative rehabilitation in patients with total hip arthroplasty (THA) without drainage. Methods Totally 84 THA patients from Zhejiang Provincial People′s Hospital were recruited in this study during April 2015 to March 2016 by using purposive sampling method. According to the random number table (i.e. hospital ID),the participants were divided into the intervention group (n=42) and the control group (n=42). Patients in the control group received drainage tubes after THA,and started walking training after removing the tubes. However,patients in the intervention group didn′t receive drainage tubes after THA but received ice compress,and started walking training within 24 hours after surgery. The postoperative complications,the pain, swelling degree,hemoglobin change,time of recoving independent walking,activities of daily living (ADL),and average inpatient days of patients in two groups were observed and compared.Results The pain scores within 24 hours and 25-48 hours after surgery for the intervention group were (2.38±1.13) and (1.90±1.06),which were lower than the scores [(3.26±1.38) and (2.41±1.0)] for the control group (t=3.283,2.487;P<0.05). But the pain scores 49-72 hours after surgery had no statistical differences between two groups (t=-1.185;P>0.05). Similarly,there were no differences between two groups in wound swelling and hemoglobin change (t=-1.221,-0.294;P>0.05). The ADL scores one week and two weeks after THA surgery for the intervention group were (70.12±9.96) and (75.00±7.89),which were higher than the scores [(64.52±9.9) and (70.21±9.3)] for the control group (t=2.577,2.588;P<0.05). While the ADL scores that one month after surgery had no statistical differences between two groups (t=-1.185,P>0.05). The time of recoving independent walking in the control group was longer than that in the intervention group [(3.71±1.59) d vs (5.20±2.03) d;t= -3.848;P<0.05]. The average hospitalization time in the intervention group was shorter than that in the control group [(9.29±4.03) d vs (11.07±3.28) d;(t=2.283;P<0.05)]. No complications (e.g. dislocation,infection,and symptomatic deep venous thrombosis) were observed after three months′ follow-up.Conclusions The ice compress combined with early walking training is beneficial for postoperative rehabilitation in THA patients without drainage. It can improve patients′ independent walking function and self-care ability and can accelerate the rehabilitation process.
