Objective To investigate the diagnostic and therapeutic value of single-use mother-baby choledochoscope-assisted endoscopic retrograde appendicitis therapy in the treatment of acute uncomplicated appendicitis.Methods A retrospective analysis was conducted on the clinical data of 39 patients with acute uncomplicated appendicitis who underwent single-use mother-baby choledochoscope-assisted endoscopic retrograde appendicitis treatment at the Endoscopy center of the hospital from September 2022 to September 2024.Observe the endoscopic manifestations,the rate of maternal and child basket stone removal,the rate of appendiceal stent implantation,the technical success rate,the clinical success rate,the operation time,the hospital stay,the incidence of complications,the visual analogue scale(VAS)score 6 hours after the operation,and the inflammatory indicators 24 hours after the operation.Results In 28 cases(71.8%),congestion and edema could be seen at the opening of the appendix under colonoscopy.In 10 cases(25.6%),pus could be seen flowing out of the opening of the appendix under colonoscopy.In 32 cases(82.1%),a large amount of pus could be seen in the lumen of the appendix under subscopy.In 20 cases(51.3%),appendiceal fecalith could be seen in the lumen of the appendix under subscopy.The technical success rate of single-use mother-baby choledochoscope-assisted endoscopic retrograde appendicitis treatment was 100.0%(39/39).The operation time was(21.08±7.49)min;Hospital stay:(3.97±2.08)days;Eight cases(20.5%)of patients underwent endoscopic maternal basket stone removal.Appendiceal stent implantation was performed in 14 cases(35.9%)of patients.The clinical success rate is 97.4%(38/39).One patient's clinical symptoms and inflammatory indicators did not improve after the operation,and was transferred to the surgery department for appendectomy.The VAS score of 38 patients was less than 3 points 6 hours after the operation,and the abdominal pain symptoms were significantly relieved.The white blood cell count and the percentage of neutrophils 24 hours after the operation decreased significantly compared with those before the operation,and the differences were statistically significant(P<0.05).None of the 39 patients had complications.The postoperative follow-up was(5.94±4.03)months,and recurrence occurred in 3 cases(7.7%).Conclusion single-use mother-baby choledocoscope-assisted endoscopic retrograde appendicitis therapy is safe and effective in the diagnosis and treatment of acute uncomplicated appendicitis,which is worthy of further promotion and popularization in clinical practice.

ObjectiveTo investigate the feasibility and safety of endoscopic retrograde cholangiopancreatography （ERCP） combined with oral cholangiopancreatography in the treatment of major duodenal papilla gallbladder polyps. MethodsA retrospective analysis was performed for the clinical data of eight patients with choledocholithiasis and gallbladder polyps who underwent ERCP and combined with oral cholangiopancreatography for major duodenal papilla cholecystectomy in Center of Digestive Endoscopy， Jilin People’s Hospital， from May 2022 to June 2024， and related data were collected， including the success rate of surgery， the technical success rate of gallbladder polyp removal， the superselective method of cystic duct， the time of operation， the time of gallbladder polyp removal， and surgical complications. ResultsBoth the success rate of surgery and the technical success rate of gallbladder polyp removal reached 100%， and of all eight patients， three patients used guide wire to enter the gallbladder under direct view， while five patients received oral cholangiopancreatography to directly enter the gallbladder. The time of operation was 51.88±12.34 minutes， and the time of gallbladder polyp removal was 23.13±10.94 minutes. The diameter of gallbladder polyp was 2‍ ‍—‍ ‍8 mm， and pathological examination showed inflammatory polyps in three patients， adenomatous polyps in one patient， and cholesterol polyps in four patients. There were no complications during or after surgery. The patients were followed up for 2‍ ‍—‍ ‍27 months after surgery， and no recurrence of gallbladder polyp was observed. ConclusionOral cholangiopancreatography is technically safe and feasible in endoscopic major duodenal papilla cholecystectomy.

Objective:To evaluate the feasibility and safety of endoscopic retrograde cholangiopancreatography (ERCP) combined with peroral cholangioscopy in the treatment of gallbladder stones with common bile duct stones.Methods:Clinical data of 19 patients with gallbladder stones and common bile duct stones admitted to the Digestive Endoscopy Center, Jilin People’s Hospital from July 2019 to November 2024 were retrospectively analyzed, including 13 males and 6 females, aged (68.2±14.2) years. All patients underwent ERCP combined with peroral cholangioscopy. Perioperative data, including the long diameter of the common bile duct stone, the long diameter of the gallbladder stone, the number of stones, ERCP operative time, gallbladder stone extraction time, stone clearance status, hospitalization duration, and complications, were recorded. Postoperative follow-up was conducted through outpatient visits or telephone consultations to monitor recurrence.Results:The long diameter of the common bile duct stones was (9.55±2.86) mm, and the long diameter of the gallbladder stones was 4.0(3.0, 5.5) mm. Among the 19 patients, 5 had single gallbladder stones, and 14 had multiple stones. The ERCP operative time was (49.0±18.4) min, and the gallbladder stone extraction time was (25.0±11.7) min. The methods used for handling the gallbladder neck were as follows: two cases involved stone removal after 6 mm balloon dilation; six cases involved stone removal after metal stent placement; three cases involved the placement of a plastic stent in the gallbladder for three months, followed by stone extraction using ERCP combined with peroral cholangioscopy; eight cases were treated directly for stone removal without specific procedures. Among the 19 patients, 11 completed stone removal within one treatment, while eight required a second treatment. All patients had complete clearance of both common bile duct and gallbladder stones under direct peroral cholangioscopy. No severe complications occurred postoperatively, although two cases developed post-ERCP pancreatitis. The postoperative hospitalization time was 8.0 (6.0, 10.0) d. The follow-up duration for the 19 patients was 14.0 (8.5, 20.0) months. One patient had a recurrence of gallbladder stones 12 months postoperatively, while no other patients had recurrence at the final follow-up.Conclusion:ERCP combined with peroral cholangioscopy is a safe and feasible approach for treating gallbladder stones with common bile duct stones.

Objective:To apply digital analysis to quantify hyperechogenicity of substantia nigra, and explore its clinical value for diagnosis of Parkinson′s disease (PD).Methods:The cross-sectional study included 652 PD patients (PD group) and 99 healthy controls (healthy control group) from November 2017 to October 2020 in Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology. All subjects underwent transcranial sonography. The diagnostic accuracy of substantia nigra hyperechogenicity using digital analysis was compared with that in a manual measurement in PD. Furthermore, the receiver operating characteristic (ROC) curve analysis was applied to explore its diagnosis value in PD.Results:There were 482 subjects including 400 in the PD group and 82 in the healthy control group, whose quantified results of substantia nigra hyperechogenicity could be used for analysis. The ROC analysis showed that the area under the curve of the quantified larger substantia nigra hyperechoic region detection for diagnosing PD was 0.858 (95% CI 0.805-0.910), the sensitivity was 87.8%, and the specificity was 73.2%, consistent with that of doctors (area under the curve: 0.884). Further more, among these PD patients, there was no correlation between larger substantia nigra hyperechogenicity and age, age of onset, course of disease, non-motor symptoms, and motor symptoms (all P>0.05). Conclusions:Digital analysis was used to quantify the changes in substantia nigra hyperechogenicity in this seudy. The results showed that diagnostic accuracy for PD based on digital analysis was consistent with that of experienced clinicians.

Objective:Analyze the operation mode of the valuation investment of scientific and technological achievements in hospitals, and provide a certain reference for other hospitals to carry out valuation investment in scientific and technological achievements.Methods:This paper analyzed the origin and current situation of the valuation investment of scientific and technological achievements. Taking Peking University Cancer Hospital as an example, it made an in-depth analysis of the valuation investment model of scientific and technological achievements.Results:The study found that the valuation investment of scientific and technological achievements in hospitals includes several key links such as signing the Valuation Investment Agreement, signing the Shareholder Agreement and the Articles of Association, the registration and identification of technical contracts, the issuance of invoices, and deferred taxation. And several suggestions on how to apply this model for the transformation of scientific and technological achievements were put forward.Conclusions:Although the implementation process of scientific and technological achievements is cumbersome, the operation mode is diverse, and the ownership of equity is difficult to distinguish, the advantages are extremely obvious. It can closely combine technological capital and industrial capital, form a strong and effective technological alliance and a community of multiple interests, better use the market-oriented motivation of scientific and technological innovation, and carry out cutting-edge research in line with market prospects.

ObjectiveTo investigate the safety and efficacy of endoscopic retrograde cholangiopancreatography （ERCP） combined with electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system in the treatment of difficult choledocholithiasis. MethodsA retrospective analysis was performed for the clinical data of 12 patients with difficult choledocholithiasis who underwent ERCP and electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system in Department of Gastroenterology， Jilin People’s Hospital， from May to November 2022. The clinical effect of lithotripsy and lithotomy was observed， and postoperative complications and time of surgical operation were assessed. ResultsAmong the 12 patients， 11 （91.67%） were successfully treated by electrohydraulic lithotripsy under direct view， 9 （75.00%） achieved first-attempt success in lithotripsy， and 11 （91.67%） had complete removal of calculi； 1 patient was found to have stenosis of the bile ducts caused by multiple biliary tract surgeries， and grade Ⅱ intrahepatic bile duct stones above the sites of stenosis were removed under direct view， but there were still residues of grade Ⅲ intrahepatic bile duct stones， which led to the fact that complete calculus removal was not achieved. The mean time of ERCP operation was 91.3±26.2 minutes， including a time of 41.8±22.2 minutes for energy lithotripsy. There were 2 cases of postoperative biliary tract infection which were improved after anti-infective therapy， 2 cases of hyperamylasemia which were not given special treatment， and 3 cases of mild pancreatitis which were improved after symptomatic medication， and there were no complications such as bleeding and perforation. ConclusionERCP combined with electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system is safe， effective， and feasible in the treatment of difficult choledocholithiasis.
