Reviewing and writing expert consensus in a scientifically rigorous manner / 中华消化外科杂志

The development of medicine has shifted from empirical medicine to evidence-based medicine, providing more scientific and precise clinical evidence for the diagnosis and treat-ment of human diseases, and to guide clinical practice and bring benefits to patients. However, there are still some diseases for which it is difficult to obtain large-scale evidence-based medical evidence for various reasons, especially some rare diseases and difficult and serious diseases. These rare diseases and difficult and serious diseases are often difficult to diagnose and treat in clinical practice, and need guidance and advice from highly qualified experts, thus, various expert consensuses have emerged. The authors analyze the recent expert consensus in the field of digestive diseases at home and abroad, and focus on the methods and pathways for the development of the international common clinical expert consensus. It is proposed that the current stage is in line with China's national condi-tions, based on the international perspective, and mastering the international consensus Delphi pathway, in order to further standardizing the method of developing expert consensus in the clinical field of China, significantly improve the academic level of expert consensus in China, provide scientific, standardized, and international-level expert consensus for the majority of clinical workers, and finally serve the majority of patients and ultimately serving clinical patients.

Evaluation of Chinese clinical practice guideline/consensus for digestive diseases / 中华消化杂志

Objective To evaluate Chinese clinical practice guideline/consensus for digestive diseases published in the past five years in order to recommend the high-quality guidelines and help with the promotion and implementation of them.Methods From January 2013 to June 2018,the officially published Chinese practice guideline/consensus for digestive diseases were selected.The inclusion and exclusion criteria of the guideline/consensus was evaluated by " Evaluation Criteria for Chinese Clinical Practice Guidelines 2017 (AGREE-China 2017)".The guideline/consensus were independently scored by three evaluators and then calculated the average value.Descriptive analysis methods were used to analyze the Chinese clinical practice guideline/consensus for digestive diseases.Those with the total score more than 40.0 points were included in the recommended list.Results A total of 119 officially published clinical practice guideline/consensus of digestive diseases were retrieved,and 74 clinical practice guideline/consensus for digestive diseases were included in the evaluation.Among them,18 (24.3％,18/74) scored over 60.0 points,31 (41.9％,31/74) scored between 40.0 and 59.9 points.Finally 48 guideline or consesus were selected for the recommended list 19 cases of esophagus and gastrointestinal diseases,18 cases of liver diseases,five cases of biliary and pancreafic diseases,and six cases of digestive endoscopy.The three guideline/consensus with the high scores (＞ 80.0 points) were The Fifth Chinese National Consensus Report on the Maragement of Helicobacter pylori Infection,Consensus on the Diagnosis and Treatmeat of Cholestatic Liver Disease (2015) and Guidelines for the Prevention and Treatment of Chroaic Hepatitis B (2015 Update).The higher the score of the guideline/consensus,the more scientific and rigorous the method,and the clearer the evaluation of evidence grade and the description of the formation of recommendations.Compared with international standards of guideline/consensus development,there are still some problems in Chinese guidelines or consensus such as no explanation of retrieval strategy,no basis of evidence classification and no description of the formation process from evidence to recommendation.Conclusions The quality of Chinese clinical practice guideline/consensus for digestive diseases has been improved year by year.However the scientific aspects need to be further improved.AGREE-China which demonstrates good validity,realiability and practicability is easy and clear to use.

The higher the score of the guideline/consensus, the more scientific and rigorous the method, and the clearer the evaluation of evidence grade and the description of the formation of recommendations. Compared with international standards of guideline/consensus development, there are still some problems in Chinese guidelines or consensus such as no explanation of retrieval strategy, no basis of evidence classification and no description of the formation process from evidence to recommendation.@*Conclusions@#The quality of Chinese clinical practice guideline/consensus for digestive diseases has been improved year by year.

Detection of Helicobacter Pylori Functional OipA Gene and Its Significance / 现代检验医学杂志

Objective To evaluate the relationship between functional oipA gene of Helicobacterpylori and digestive disease. Methods Biopsy gastric mucosa were obtained from 360 patients who would get gastroscopy.Hp were isolated from urease positive samples and partly urease negative samples,and improved by microscope,urease experiment and 16SrRNA PCR. OipA and cagA of the isolates were obtained by PCR and the statas of oipA signal region were analysised after sequencing. Analyze the relevance between functional oipA gene of Helicobacter pylori and digestive disease.Results 106 isolated Hp were obtained,in which 72 strains with cagA gene positive,87 with oipA signal region gene positive (80 the statas of signal region was on and 1 was off;6 could not be decided).The frequency of functional oipA were both significantly higher than cagA in ulcer and atrophic gastritis.Conclusion The relationship between functional oipA gene and digestive disease was more closer than that of cagA.

Adipocyte Signals in Energy Balance and Digestive Diseases / 대한소화기학회지

For the regulation of energy balance in various internal organs including gut, pancreas and liver, visceral adipose tissue and brain perform important sensing and signaling roles via neural and endocrine pathway. Among these, adipose tissue has been known as a simple energy-storing organ, which stores excess energy in triglyceride. However, it became apparent that adipocytes have various receptors related to energy homeostasis, and secrete adipocytokines by endocrine, paracrine and autocrine mechanisms. In this review, basic roles of adipocytes in energy homeostasis and the correlation between adipocyte signals and digestive diseases are discussed.

The effect of compound azintamide on abdominal fullness in patients with functional dyspepsia, chronic cholecystitis or liver cirrhosis / 中华消化杂志

Objective To investigate the effect of compound azintamide enteric-coated tablet on abdominal fullness in patients with functional dyspepsia, chronic cholecystitis with gallbladder stones, or liver cirrhosis. Methods Twenty patients with functional dyspepsia, 20 with chronic cholecystitis and gallbladder stones, and 20 with liver cirrhosis were enrolled in the study. Compound azintamide enteric-coated tablets were given 2 tablets 3 times daily for 4 weeks. The changes of symptom scores of abdominal fullness were investigated after the treatment. Water loading tests were carried out in patients with functional dyspepsia and chronic cholecystitis with gallbladder stones before and after the medication. Results Compound azintamide enteric-coated tablets greatly improved the symptom of abdominal fullness in each group of patients. Symptom scores were significantly decreased in 2 and 4 weeks (P
