Objective:To study the distribution and drug resistance of pathogenic bacteria of biliary tract infection in patients with hepatobiliary surgery.Methods:A total of 103 patients with biliary tract infection who received treatment in the Department of Hepatobiliary Surgery, Lanxi People's Hospital from May 2020 to October 2022 were included in this study. Their bile was cultured to analyze the distribution and drug resistance of pathogenic bacteria. The data were processed using the WHONET5.5 software system.Results:Fifty-eight pathogenic bacteria-positive samples were cultured from the bile of 103 patients with biliary tract infection, with a pathogenic bacteria-positive rate of 56.31%. Among 58 strains of pathogenic bacteria, 38 strains (65.52%) were gram-negative bacteria, mainly Escherichia coli and Klebsiella pneumonia, and 5 strains (8.62%) were fungal strains. Escherichia coli and Klebsiella pneumoniae were highly resistant to sulfamethoxazole-trimethoprim, ciprofloxacin, and other antibacterial drugs, and were completely sensitive to imipenem and meropenem. Enterococcus faecalis was mainly resistant to ampicillin and penicillin G,and it was completely sensitive to vancomycin and teicoplanin. Staphylococcus aureus was resistant to vancomycin, ciprofloxacin, cefotaxime, and other drugs. A total of 13 strains of ultrabroad-spectrum beta-lactamase bacteria were isolated from 25 strains of Escherichia coli and 7 strains of Klebsiella pneumonia, with the positive detection rate of 40.63%. Conclusion:The main pathogenic bacteria of biliary tract infection are Gram-negative bacteria, which are widely distributed and have serious drug resistance. In clinical practice, antimicrobial drugs should be reasonably selected according to the results of bile drug sensitivity tests.

Objective: To explore the immunogenicity and influencing factors of hepatitis B vaccination based on different vaccination schedules among chronic kidney disease (CKD) patients. Methods: CKD patients who participated in randomized controlled trials in four hospitals in Shanxi province and completed three doses of 20 µg vaccination (at months 0, 1 and 6) and four doses of 20 µg or 60 µg vaccination (at months 0, 1, 2, and 6) were surveyed from May 2019 to July 2020.According to the ratio of 1∶1∶1, 273 CKD patients were divided into 3 groups randomly. Quantification of the anti-hepatitis B surface antigen-antibody (anti-HBs) in serum samples was performed using chemiluminescent microparticle immunoassay at months 1 and 6 after the entire course of the vaccinations. The positive rate, high-level positive rate, geometric mean concentration (GMC) of anti-HBs, and the influencing factors were analyzed by χ² tests, analysis of variance, unconditional logistic regression analysis. Results: A total of 273 CKD patitents were participants.The positive rates in the CKD patients with four doses of 20 µg vaccination (92.96%,66/71) or 60 µg vaccination (93.15%, 68/73) were higher than that in the CKD patients with three doses of 20 µg vaccination (81.69%, 58/71) at month one after the full course of the vaccinations (P<0.05). The GMCs of anti-HBs showed similar results (2 091.11 mIU/ml and 2 441.50 mIU/ml vs. 1 675.21 mIU/ml) (P<0.05). The positive rate was higher in the CKD patients with four doses of 60 µg vaccination (94.83%,55/58) than in those with three doses of 20 µg vaccination (78.79%,52/66) (P<0.05) at month six after the full course of the vaccinations. And the GMC of anti-HBs in the patients with four doses of 60 µg vaccination (824.28 mIU/ml) was significantly higher than those in the patients with 3 or 4 doses of 20 µg vaccination (639.74 mIU/ml and 755.53 mIU/ml) (P<0.05). After controlling the confounding factors, the positive rate in the CKD patients with four doses of 60 µg vaccination were 3.19 (95%CI: 1.02-9.96) and 5.32 (95%CI: 1.27-22.19) times higher than those in the patients with three doses of 20 µg vaccination at months 1 and 6 after the full course of the vaccinations, respectively. The positive rate in CKD patients without immune suppression or hormone therapy was 3.33 (95%CI: 1.26-8.80) and 4.78 (95%CI: 1.47-15.57) times higher than those in the patients with such therapy, respectively. Conclusions: Four doses of 20 µg or 60 µg hepatitis B vaccination could improve the immunogenicity in patients with CKD. And four doses of 60 µg vaccination might play a positive role in maintaining anti-HBs in this population. The immunogenicity in the CKD patients with immune suppression or hormone therapy was poor.

To develop a high-yield pyruvate strain, we first engineered a pyruvate-producing Escherichia coli KLPP from wild-type E. coli MG1655 by blocking the pathways for byproduct formation via gene knockout. Then, we built a library of mutant containing 7 197 monoclones by using the pUT Mini-Tn5 transposon vector for random mutagenesis with E. coli KLPP. We developed a high-throughput method for pyruvate detection based on dinitrophenylhydrazine reaction using 96-well microplate reader. After two-round screening we successfully obtained six mutants with increased pyruvate titer using this method, the titer of pyruvate was increased by 38%, 31%, 19%, 28%, 44% and 14%, respectively. The position of transposon insertion was determined by whole genome re-sequencing, and the gene locus possibly influencing pyruvate production was analyzed, which laid the foundation for subsequent strain improvement by metabolic engineering.

Hepatitis B virus (HBV) infection is a common cause of liver disease in China, and with the continuous progress in the research on antiviral therapy for chronic hepatitis B, the indications for antiviral therapy are constantly expanding. However, there are still controversies over the indications for antiviral therapy in patients with chronic hepatitis B (CHB), especially those with negative HBV. By analyzing the limitations of HBV DNA detection, the risk of HBV reactivation in HBV-negative CHB patients, the risk of disease progression in the DNA-negative population with compensated hepatitis B cirrhosis, antiviral response, and the economic benefits of antiviral therapy, this article proposes the necessity of antiviral therapy for HBV-negative HBsAg-positive patients with compensated hepatitis B cirrhosis.
