This study reported two women with extreme obesity who underwent metabolic surgery due to their mutations in leptin receptor (LEPR).Genomic DNA was extracted from the anticoagulant blood samples of the two patients and their parents.A panel of genes related to metabolic diseases or whole exon sequencing was screened and the results were confirmed by Sanger sequencing.This is the first time that these three mutations in LEPR were reported.Two patients complained insatiety and early-onset obesity since childhood at clinics.Patient 1 was a 39-year-old woman with height 150 cm,weight 130 kg,and BMI 57.8 kg/m2.Serum leptin level was 156.4 μg/L.A homozygous mutation of c.2317G＞T was found in exon 15 of LEPR gene in patient 1,which was descended from her father and mother respectively.Patient 2 was a 37-year-old woman with height 158 cm,weight 167 kg,and BMI 67 kg/m2.Serum leptin level was 193.4 μg/L.Genetic analysis showed compound heterozygous mutations of c.1482delT and c.1892C ＞ A.Her father showed heterozygous c.1482delT mutation,and her mother carried heterozygous c.1892C ＞ A mutation.Two patients all underwent metabolic surgery with body weight reduction of about 22 kg and 40 kg respectively after first six months.However,the follow-up studies showed that the body weight of patient 1 rebounded to pre-surgery level in two years and patient 2 did not further lose weight in the following six months.

Objective:To preliminarily understand the living habits, medication taking and treatment status including the therapeutic regimen, compliance and short-term efficacy of patients with chronic atrophic gastritis and erosion in Beijing area.Methods:From April to September in 2019 at Peking Union Medical College Hospital, Peking University Third Hospital and Peking University Shougang Hospital, the outpatients with chronic atrophic gastritis and erosion diagnosed with endoscopy within two weeks before visiting were prospectively included in this non-interventional observation study. Chi square test was used for statistical analysis.Results:A total of 277 patients with chronic atrophic gastritis and erosion had complete follow-up data, of which male patients accounted for 49.8% (138/277). The common initial symptoms of patients with chronic atrophic gastritis and erosion included acid reflux, abdominal distension, epigastric pain and postprandial distension, which accounted for 60.3% (167/277), 59.6% (165/277) , 58.8% (163/277) and 52.3% (145/277), respectively. For treatment, 36.8% (102/277) of the patients only received lifestyle instruction without medication. Among the patients with medication treatment, the short-term efficacy of gastric mucosal protectants+ proton pump inhibitor+ gastro-kinetic agent for abnominal distension, postprandial distention, acid reflux and nausea was highest as compared with other therapeutic regimen, and the differences were statistically significant ( χ2=25.18, 19.49, 13.75, 8.84, all P<0.05). Conclusions:Chronic gastritis with erosion may be caused by a combination of multiple factors, and the symptoms of which lack specific. If necessary, gastroscopy may help the diagnosis. Individualized treatment strategies based on the symptoms of patients is needed for treatment.

In order to improve the management level of medicine list of medical institutions in China ，and help medical institutions build a medicine list of medical institutions with reasonable drug use structure ，standardized adjustment procedures ， convenient operation and application and scientific evaluation methods ，so as to meet the needs of clinical rational drug use to the greatest extent ，with the support of the Pharmaceutical Care Professional Committee of the Chinese Pharmaceutical Association ， China-Japan Friendship Hospital and the First Affiliated Hospital of University of Science and Technology of China （Anhui Provincial Hospital ）jointly initiate and complete Guideline for the Evaluation of Medicine List in Chinese Medical Institutions jointly with a number of medical institutions. In strict accordance with the methodological requirements of World Health Organization standard guidelines ，based on the Delphi method ，the guideline formulation working group has constructed the quality evaluation index system and quantitative scoring table of medicine list management in medical institutions from the 5 dimensions of organization and management ，structure，adjustment，application and e valuation of the list. It is used to help medical institutions evaluate the quality of their medicine list management ，so asto play a positive role in the fine management of medicine list in medical institutions.
