Objective:To analyze the distribution of pathogenic bacteria in bile culture in patients with common bile duct stones and biliary tract infections, in order to guide clinical optimization of antibiotics application.Methods:From March 30, 2017 to December 31, 2021, at Affiliated Hospital of Qingdao University, 753 patients with common bile duct stones and biliary tract infections and received endoscopic retrograde cholangiopancreatography were selected. Bile samples were obtained for bacterial culture, strain type identification and drug sensitivity test in order to analyze bile pathogenic bacteria distribution, change trend and drug resistance. Chi-square test was used for statistical analysis.Results:From 2017 to 2021, the total positive rate of bile culture in 753 patients with choledocholithiasis complicated with biliary tract infection was 90.17% (679/753). From 2017 to 2021, the positive rates of bile culture were 82.05% (64/78), 88.81% (119/134), 88.03% (125/142), 93.87% (199/212), and 91.98% (172/187), respectively, and the difference was statistically significant ( χ2=10.78, P=0.029). The positive rate of bile culture in 2017 was lower than those in 2020 and 2021, and the differences were statistically significant ( χ2=9.43 and 5.57, P=0.002 and 0.018). There were no significant differences in the positive rates of bile culture among the other years (all P>0.05). A total of 1 033 pathogenic bacteria were detected in the 679 bile specimens with positive bile culture results. Among which the total proportion of Gram-negative bacilli was 57.02% (589/1 033), and from 2017 to 2021 the proportions were 66.38% (77/116), 66.47% (111/167), 59.43% (104/175), 54.75% (173/316), and 47.88% (124/259), respectively. The total proportion of Gram-positive cocci was 41.05% (424/1 033), and from 2017 to 2021 the proportions were 31.90% (37/116), 31.74% (53/167), 38.86% (68/175), 44.30% (140/316), and 48.65% (126/259), respectively. The total proportion of fungus was 1.94% (20/1 033), and from 2017 to 2021 the proportions were 1.72% (2/116), 1.80% (3/167), 1.71% (3/175), 0.95% (3/316), and 3.47% (9/259), respectively. From 2017 to 2021, the proportion of Gram-negative bacilli gradually decreased, while the proportion of Gram-positive cocci gradually increased, and the differences were statistically significant ( χ2=20.14 and 17.91, P<0.001 and =0.001). From 2017 to 2021, the change in the proportion of fungus was not statistically significant ( P>0.05). The main Gram-negative bacilli in the bile culture were Escherichia coli (31.36%, 324/1 033) and Klebsiella pneumoniae (12.68%, 131/1 033); the main Gram-positive cocci were Enterococcus faecalis (14.04%, 145/1 033) and Streptococcus salivarius (4.36%, 45/1 033). From 2017 to 2021, the proportions of Escherichia coli were 39.66% (46/116), 38.92% (65/167), 33.14% (58/175), 28.48% (90/316), and 25.10% (65/259), respectively, with gradual decrease and the difference was statistically significant ( χ2=14.34, P=0.006). From 2017 to 2021 the detection rates of extended-spectrum β-lactamase (ESBL) in Escherichia coli and Klebsiella pneumoniae were 30.43% (14/46), 26.15% (17/65), 29.31% (17/58), 38.89% (35/90), 40.00% (26/65), and 4/15, 20.00% (5/25), 20% (5/25), 24.32% (9/37), and 31.03% (9/29), and there were no significant differences in the detection rates of ESBL between different years (both P>0.05). Conclusions:From 2017 to 2021, the positive rate of bile culture in patients with choledocholithiasis complicated with biliary tract infection showed an overall increasing trend. Gram-negative bacilli were still dominated in bile pathogenic bacteria, while the proportion of Gram-positive cocci remarkably increased, and the bile bacterial spectrum significantly changed. Clinicians should adjust the antibiotic dosing regimens according to the variation of bacterial spectrum and drug resistance.

Objective To investigate the risk factors and clinical characteristics of gastric inflammatory fibroid polyp(GIFP)for gastrointestinal hemorrhage.Methods 66 patients(68 lesions in total)with GIFP diagnosed by endoscopic or surgical resection from January 1,2013 to September 30,2022 were collected.According to the presence or absence of gastrointestinal hemorrhage,the patients were divided into bleeding group(n = 16)and non-bleeding group(n = 50).Collect clinical data on gender,age,clinical manifestations,lesion location and size,endoscopic characteristics,Helicobacter pylori infection,surgical methods and pathological results of each group of patients.Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of endoscopic characteristics of GIFP for gastrointestinal hemorrhage,and summarize the clinical characteristics of GIFP with gastrointestinal hemorrhage,then calculate the rate of correct diagnosis.Results The age of the bleeding group was significantly younger than that of the non-bleeding group,and the lesion size was significantly larger than that of the non-bleeding group,with statistically significant differences(P＜0.05).The incidences of endoscopic neoplasm-like elevation of lesions,surface with erosion or ulceration,accompanied by ballvalve syndrome and ultrasonic gastroscopy with blood flow signals in the bleeding group were significantly higher than those in the non-bleeding group,and the differences were statistically significant(P＜0.05),but there were no statistical differences in other indicators between the two groups(P＞0.05).In order to further investigate the relationship between endoscopic characteristics and gastrointestinal hemorrhage,multivariate Logistic regression analysis showed that neoplasm-like elevation,submucosal eminence,ulcer or erosion on the surface and ball valve syndrome were risk factors for gastrointestinal hemorrhage in GIFP(O(R)＞1,P＜0.05).The overall rate of GIFP correct diagnosis before surgery was 27.94%.The rate of diagnosis in patients echoendoscope before surgery was 38.78%,it was significantly higher than that without undergoing echoendoscope(χ2 = 20.82,P = 0.000).Conclusion The shape of the lesion,presence of ulcers or erosion on the surface,and presence of ball valve syndrome are risk factors for gastrointestinal hemorrhage.Preoperative endoscopic ultrasonography can improve the accuracy of preoperative diagnosis.When there is a risk of gastrointestinal hemorrhage in GIFP,early endoscopic diagnosis and therapeutic resection should be performed to avoid unnecessary surgical procedures,which can improve prognosis and improve patient quality of life.

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.
