Objective To evaluate the therapeutic effect of abdominal multiple visceral organ transplantation for hepatic cirrhosis combined with diabetes by using donation after cardiac death (DCD).Methods Two patients suffering from hepatitis B-related liver cirrhosis,hepatocellular carcinoma combined with insulin dependent type 2 diabetes mellitus were given multiple visceral organ transplantation from May to June 2012.The transplanted organs including the liver,pancreas and duodenum were obtained from two donors after cardiac death which accorded with C-Ⅲ criteria.The donor internal and external iliac arteries were anastomosed to celiac axis and superior mesenteric artery and then the donor arteria iliaca communis was anastomosed to recipient abdominal aorta.The portal vein reconstruction was performed by end-to-side anastomosis between the donor and recipient portal vein.The pancreatic juice drainage was achieved by side to side anastomosis between donor duodenum and recipient jejunum.The pancreases of recipients were retained.Results The alanine aminotransferase,aspartate aminotransferase and total bilirubin of two patients were recovered to normal level at 2nd week after operation.The blood glucose and serum amylase returned to normal levels at 7th d and 4th d respectively.The fasting serum C-peptide and insulin were also at normal level at 2nd week.One patient with local intestinal anastomotic fistula was given percutaneous puncture drainage for four weeks and recovered.One patient recovered smoothly one month after transplantation without surgical complications.Conclusion Abdominal multiple visceral organ transplantation is an effective treatment for hepatic cirrhosis combined with diabetes by using DCD donor.

Primary aldosteronism(PA) is a common cause of secondary hypertension, with adrenal vein sampling(AVS)being the gold standard for etiological typing diagnosis. This retrospective study analyzed data from patients diagnosed with PA who underwent AVS or unilateral adrenalectomy at Nanjing Drum Tower Hospital′s Endocrinology Department from July 2018 to August 2021. Using multivariate logistic regression analysis, factors associated with unilateral aldosterone hypersecretion were identified. Based on these factors, a predictive model for diagnosing unilateral primary aldosteronism(UPA)was established: age <40 years, plasma aldosterone concentration(PAC)>15 ng/dL, adrenal CT indicating an unilateral typical adenoma, and spontaneous hypokalemia. This predictive model could help 14% of PA patients avoid unnecessary AVS procedures.

Polyetheretherketone (PEEK) as a new type of thermoplastic engineering plastic, has good biological activity, elastic modulus close to human cortical bone and radiation permeability, and has been widely used in medical field. This study aims to explore the safety and clinical efficacy of using 3D printing personalized PEEK materials to repaire scapular bone defects after bone tumor resection. A total of 6 patients who underwent the implantation of 3D printed PEEK scapular prosthesis from January 2020 to December 2021 in Yunnan Cancer Hospital were retrospectively analyzed. There were 3 males and 3 females, with age ranged from 14 to 52 years. There were 1 case of synovial sarcoma, 1 of Ewing's sarcoma, and 4 of chondrosarcoma. PEEK prosthesis was designed and fabricated based on CT data before surgery. Tumor resection and prosthesis replacement were performed under the premise of ensuring safe surgical boundaries, including 2 cases of total scapular prosthesis replacement and 4 cases of partial scapular prosthesis replacement. The operation time was 90-170 min, and the intraoperative blood loss was 100-400 ml. All 6 patients received satisfactory follow-up, with a tumor progression free survival time of 16-28 months. No tumor recurrence or metastasis was observed, and all patients survived tumor free. At last follow-up, the Constant-Murley shoulder joint score was a minimum of 62 points and a maximum of 68 points. The Japanese Orthopaedic Association's shoulder joint score was 63 points minimum and 78 points maximum. Computer-aided design 3D printing PEEK material prosthesis has certain advantages in the treatment of scapular tumor limb salvage. It has light weight, well adapted, relatively simple installation, good histocompatibility, and can obtain a better appearance and function of the shoulder joint after operation. It can become one of the options for limb salvage treatment of scapular tumor.

Background: Helicobacter pylori (Hp) infection is related to the occurrence of many upper digestive tract diseases, and the eradication rate has been decreasing year by year. Aims: To investigate the risk factors affecting initial eradication rate of Hp infection. Methods: Clinical data of 428 patients with Hp infection were retrospectively analyzed. Four regimens (14-day esomeprazole 20 mg + amoxicillin 750 mg, qid; 10-day esomeprazole 20 mg + amoxicillin 750 mg, qid; 14-day esomeprazole 20 mg + amoxicillin 1 000 mg, tid; 14-day esomeprazole 20 mg + bismuth 220 mg + amoxicillin 1 000 mg + clarithromycin 500 mg, bid) were given, and effect of antibiotic resistance on Hp eradication was analyzed, the relevant risk factors affecting the eradication rate of Hp were investigated. Results: The eradication rate of ITT analysis was 86.4%, PP analysis was 87.6%. The eradication rates of 4 regimens for ITT analysis were 90.8%, 79.8%, 82.7%, 91.9%, respectively, and were 90.8%, 81.2%, 85.1%, 92.7% for PP analysis, respectively. The antibiotic resistance rate was 30.3%, 97.4% and 36.8% for clarithromycin, metronidazole and levofloxacin, respectively. The recurrence rate of 116 patients was 4.3% after one year of eradication. Smoking, poor compliance, CYP2C19 gene polymorphism were risk factors for eradication rate of Hp (P<0.05). Conclusions: Smoking, poor compliance and ultra-rapid metabolizers, extensive metabolizers of CYP2C19 gene polymorphism can reduce Hp eradication rate. In clinical practice, patient education should be strengthened to urge patients to quit smoking. The quality of follow-up should be improved and proton pump inhibitor that has less impact on CYP2C19 gene polymorphism should be used, thereby increase the Hp eradication rate.

Background: The increasing in antibiotic resistance of Helicobacter pylori (Hp) has become the main cause leading to the decreasing of the eradication rate for Hp treatment. Aims: To investigate the risk factors of drug resistance of Hp. Methods: Data on 396 patients with Hp infection from Dec. 2016 to Mar. 2021 at Army Medical University were retrospectively analyzed. Drug susceptibility test was used to evaluate the resistance of 6 antibacterial drugs (metronidazole, clarithromycin, levofloxacin, amoxicillin, tetracycline and furazolidone). Unconditional Logistic regression was used to investigate the risk factors affecting Hp antibiotic resistance. Results: In 396 patients with Hp infection, the resistance rates of metronidazole, clarithromycin, levofloxacin, amoxicillin, tetracycline and furazolidone were 96.5%, 45.5%, 41.9%, 0.3%, 0.3% and 0, respectively. Multivariate analysis showed that previous regimen containing clarithromycin was a risk factor for clarithromycin resistance (P<0.001), and age > 40 years old was a risk factor for levofloxacin resistance (P< 0.001). Conclusions: The resistance rates of metronidazole, clarithromycin and levofloxacin are relatively high, and regimens containing these antibiotics should be avoided without the support from drug susceptibility results, especially in patients who have accepted clarithromycin‑containing regimen or more than 40 years old. Amoxicillin, tetracycline and furazolidone should be recommended preferentially for Hp treatment empirically.
