Wnt/β-catenin is a signaling pathway associated with embryonic development, organ formation, cancer, and fibrosis. Its activation can repair kidney damage during acute kidney injury (AKI) and accelerate the occurrence of renal fibrosis after chronic kidney disease (CKD). Interestingly, p53 has also been found as a key modulator in AKI and CKD in recent years. Meantime, some studies have found crosstalk between Wnt/β-catenin signaling pathways and p53, but more evidence is required on whether they have synergistic effects in renal disease progression. This article reviews the role and therapeutic targets of Wnt/β-catenin and p53 in AKI and CKD and proposes for the first time that Wnt/β-catenin and p53 have a synergistic effect in the treatment of renal injury.

Objective:To explore the application of metagenomic next-generation sequencing (mNGS) in patients with pulmonary infection after failure of empirical treatment.Methods:From September 2021 to November 2023, a total of 64 patients with pulmonary infection who failed to receive empirical treatment in the Ninth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were retrospectively analyzed, sputum and bronchoalveolar lavage fluid of patients were collected for traditional etiological detection and mNGS detection in alveolar lavage fluid, and the differences between traditional etiological detection methods and mNGS detection methods for pathogen detection in patients with pulmonary infection after failure of empirical treatment were compared.Results:In 64 patients with pulmonary infection after failure of empirical treatment, the positive rate of mNGS microbial detection in alveolar lavage fluid was higher than that of traditional etiological detection: 87.50%(56/64) vs. 57.81%(37/64), and the difference was statistically significant ( P<0.01). The most common microorganisms detected by mNGS were bacterial infections, the main bacteria were Pseudomonas aeruginosa, Klebsiella pneumoniae and Haemophilus paraininfluenzae. The detection rate of mNGS in mixed infection was higher than that of traditional etiological detection: 65.63%(42/64) vs. 15.63%(10/64), χ2 = 33.17, P<0.01. Drug resistance genes were detected by mNGS technique in 18 patients, and a total of 21 kinds of drug resistance genes were detected, 53.13%(34/64) of patients improved after antibiotic adjustment based on mNGS test results. Conclusions:mNGS technology can effectively improve the positive microbial detection rate of patients with pulmonary infection after failure of empirical treatment, and can assist in the evaluation of antimicrobial resistance genes and guide the adjustment of clinical antibiotics, so as to improve the therapeutic effect.

[Objective] To investigate the effects of advanced male age on the incidence of polyspermy fertilization. [Methods] The study involved data of 4210 in vitro fertilization (IVF) cycles treated in our center during Jan.2016 and Sep.2022, including 4053 patients younger than 40 years and 157 patients above 40 years.After propensity score matching, 152 patients in the advance group and 421 in the young group were recruited.The baseline data and the difference in polyspermy fertilization rate were compared between the two groups. [Results] After propensity score matching, there were no significant differences between the two groups in terms of female age, infertility type, infertility years, infertility factors, female body mass index (BMI), male BMI, semen volume, semen pH value, sperm concentration, sperm motility, progressive motility rate, percentage of normal sperm morphology, number of fertilized eggs and number of MⅡ eggs (P>0.05). Among the 573 fresh IVF cycles, the rate of 3 PN cycles was 35.5%, and the incidence of polyspermy fertilization was 6.5%.There were no significant differences in the number of polyspermy fertilized eggs, transferable embryos, high-quality embryos, and blastocysts between the two groups. [Conclusion] Advanced male age has no significant effect on the incidence of polyspermy fertilization.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

OBJECTIVES: This study aimed to investigate the association between periodontal indexes and biomarkers in gingival crevicular fluid (GCF) and preterm birth (PTB) in pregnancy, as well as to assess the clinical value of these indexes as predictors of PTB. METHODS: A nested case-control study was conducted. A total of 300 systematically healthy pregnant women were selected within 36 weeks of gestation and grouped according to the enrolled weeks. Periodontal indexes, including probing depth (PD), bleeding index (BI), gingival index (GI), and five biomarkers in GCF, including interleukin (IL)-1β, IL-6, tumor necrosis factor-α (TNF-α), prostaglandin E2 (PGE2), and 8-hydroxy-2-deoxyguanosine (8-OHdG) were measured at the enrolled date. The detailed birth outcome was recorded. RESULTS: Only women at 24-28 weeks of gestation per PTB case (four full-term births) were selected as controls subjects, PTB displayed significantly greater GI, BI, and 8-OHdG ( CONCLUSIONS Increased BI and 8-OHdG at 24-28 weeks of gestation are risk factors for PTB. Their combined detection may have some value in the prediction of PTB, but further studies with a larger sample size are needed to explore it and thus provide experiment evidence for establishing an early warning system for PTB in pregnant women with periodontal disease.
