The study of relation between hepatogenic peptic ulcer and portal hypertension,transmitter metabolic disturbance,hepatic insufficiency and infection;and the therapeutic principles of complications of peptic ulcer are described.Twenty four of 58 patients with hepatogenic peptic ulcer were examined by color Doppler ultrasound.Portal venous flow volume (24 cases) was 1060.9±96ml/min.Portal venous pressure(8 cases)was 3.77±2.51kPa tested during operation.Histamine concentration (8 cases) was 0.70±0.31μmol/L in peripheral blood.The gastrin contents of 9cases tested 3cm,5cm away from the ulcer were 2195.6±1043.89ng/L and 2140.3±978.5ng/L respectively. H pylori positive rate was 80% in 58 cases.The therapeutic results were satisfactory with no death.The results suggest that pathogenesis of hepatogenic peptic ulcer is closely related to these factors foresaid.The treatment is nonsurgical and massive hemorrhage or perforation once occurs,surgical treatment is necessary.
Objective To investigate the clinical typing and their relevant surgical treatment principle and method of pressure sore. Methods From January 1983 to April 2006, 122 patients with 179 pressure sores were treated. There were 93 males and29 females, aging 1568 years. The pressure sores were located at sacrococcygeus (54 lesions), petrochanteric region (37 lesions), ischial tuberosity (30 lesions), heel (17 lesions), olecranon (15 lesions), scapula (9 lesions), lateral malleolar (7 lesions), caput fibulace (4 lesions), pretibial (3 lesions), and lumbar region (3 lesims)respectivly. The disease course was from 2 months to 11 years. The areas of pressure sores were from 1.5 cm× 1.0 cm to 20.0 cm×18.0 cm. According to the wound characteristics, the pressure sores were divided into three types：sinus type（12/179）, ulcer type （74/179） and mixed type（93/179）.Aimed at different types of pressure sore, skin grafting, skin flap and myocutaneous flap were employed to repair wound. The areas of flaps were from 5.0 cm×3.5 cm to 26.0 cm×14.5 cm. The areas of skin grafting were from 7 cm×5 cm to 23 cm×12 cm. Results All wounds of sinus type healed by firstintention except one; and all flaps survived. All wounds of uler type healed byfirst intention; and the flaps survived completely except two which had a partial necrosis. All flaps which harvested to repair 93 pressure sores of mixed typewere survived. But one or two sinus occurred in 8 cases. Two healed by operation, and the others healed by dressing exchange. The wounds healed by first intention. The donor sites healed by first intention. The routine followup in 73 patients after 6 months showed that the recurrence appeared in 4 mixed type. The recurrence rate was 55% and the other patients had good outcome. Conclusion Clinical typing of pressure sore is helpful to select the suitable operation method and improve the rate of success.
The data collection form is a bridge in-between the original studies and the final systematic reviews. It’s the basis for data analyses, directly related to the results and conclusions of systematic reviews, and plays an important role in systematic reviews. There are strict requirements of data collection forms in making Cochrane systematic reviews. In this article, the authors introduce their experiences regarding to the design of data collection form.
Objective To describe the criteria and procedure for defining an essential healthcare package in the developed and developing countries. Method Search words were chosen by both health policy experts and search coordinators after discussion and pilot. We searched electronic databases, websites of health institutions and governments and search engine Google. Any reports of implemented strategy to develope an essential healthcare package were included. Pre-designed data extraction form was used for collecting strategies and study method of included studies. Then the extracted information was analyzed and described. Result One hundred and sixty-six studies covering 72 countries were included, most of which were studies in the middle and low Countries. In terms of study objective,160 articles aimed to describe strategies, 6 articles aimed to evaluate effectiveness of strategies.Five studies evaluating effectiveness were cross-sectionnary data, and one study was time series. Conclusion An appropriate package should be defined according to both technique criteria and social welfare criteria, considering each country’s healthcare system and market structure, characteristics of the demander and provider, capacity of government’s regulation. The experience in transition countries gives us more high lights.
ObjectiveTo introduce and interpret ABCD classification system for subaxial cervical spine injury. MethodsThe literature related to subaxial cervical spine injury classification system was extensively reviewed, analyzed, and summarized so as to introduce the ABCD classification system. ResultsThe ABCD classification system for subaxial cervical spine injury consists of 3 parts. The first part of the proposed classification is an anatomical descri ption of the injury; it del ivers the information whether injury is bony, ligamentous, or a combined one. The second part is the classification of nerve function, spinal stenosis, and spinal instabil ity. The last part is optional and denotes radiological examination which is used to define injury type. Several letters have been used for simplicity to del iver the largest amount of information. And a treatment algorithm based on the proposed classification is suggested. ConclusionThe ABCD classification system is proposed for simplification. However further evaluation of this classification is needed.
In order to help Chinese guideline developers, clinicians, health policy makers and other relevant researchers fully understand and make appropriate use of World Health Organization (WHO) guidelines, Chinese GRADE Center and Guidelines Review Committee of World Health Organization (WHO-GRC) have written a series of papers about development methods, review principles and the structure and content of WHO guidelines. This is the second paper of this series introducing the composition, main work and functions of WHO-GRC.
National Center for Medical Service Administration of National Health and Family Planning Commission of China was established at the beginning of 2015. It is mainly in charge of developing and managing standards of medical technology and organizing their implementation, and giving technical guidance and consulting for evaluation of medical institutions. The foundation of the center fills in the blank of lacking central administrative department of the guideline development and evaluation. This paper introduces the definition and the function of clinical practice guideline, and analyzes the current situation, problems and challenges of domestic guidelines, and proposes some potential suggestions on improving the quality of Chinese guidelines from national level for promoting the standardization, scientification and transparency of clinical practice guidelines in China.
In order to fully implement the ethical principles of biomedical researches and to better safeguard the legitimate rights and interests of the subjects, this paper begins from the research design and closely combines with the ethical practice of biomedical research review, seriously analyzes the key implementation points of the ethical free and compensation principles in biomedical research, including intervention study, random allocation, follow-up research and new medical techniques and so on, also will provide the beneficial reference for comprehensive formulation of enforcement regulation of ethics principle of biomedical research in the future.
As an important part of social governance, the health poverty alleviation plays a key role in promoting Healthy China Strategy. This paper reviews the practice progress of health poverty alleviation in China, and summarizes it's four action logics. It is found that the governance effect is restrained by several issues, such as pessimistically external governance environment, single governance subject, poor leading role of the pilot areas, specific practices inconsistent with conceptions, and the research has not paid enough attention to the incentive system and supervision mechanism of the practitioners. Based on the above, this paper proposes five governance principles on the governance of health and poverty alleviation: evidence-based principle, systematic principle, economic principle, dynamic principle and people-oriented principle. Lastly, we hope to provide some preferences to promote the governance practice of health poverty alleviation.
