Objective:To investigate the early clinical efficacy of arthroscopic suture half-tie combined with Versalok anchor fixation in the treatment of avulsion fracture of the tibial insertion of anterior cruciate ligament (ACL) in adults.Methods:A retrospective study was conducted to analyze the clinical data of the 26 adult patients with avulsion fracture of the ACL tibial insertion who had been treated by arthroscopic suture half-tie combined with Versalok anchor fixation between June 2020 and December 2022 at Sports Medicine Center, Honghui Hospital, Xi'an Jiaotong University. This cohort consisted of 12 males and 14 females with an age of (26.6±7.5) years. According to the Meyers-McKeever classification, there were 9 cases of type Ⅱ, 12 cases of type Ⅲ, and 3 cases of type Ⅳ. The time from injury to surgery was (9.3±6.8) days. Follow-up evaluations were conducted at postoperative 3 days, 3 months, and 12 months, including imaging assessments for fracture healing, clinical examinations of knee flexion and extension, anterior drawer and Lachman tests to assess the ACL tension. At the last follow-up, KT-2000 test was performed to quantify ACL laxity, and visual analogue scale (VAS) and Lysholm knee score were used to assess postoperative pain and functional recovery.Results:Primary wound healing was achieved in all the 26 patients. One patient required ACL reconstruction due to laxity and mild extension limitation at postoperative 6 months. The other 25 patients were followed for (15.4±3.2) months. At postoperative 12 months, X-rays showed good bone healing at the fracture site of the tibial intercondylar eminence, and both the Lachman and anterior drawer tests were negative. At postoperative 3 months and the last follow-up, the active knee extension and flexion were 128.8° (121.2°, 138.3°) and 52.7° (38.2°, 63.2°), respectively, significantly better than the preoperative value [52.7° (38.2°, 63.2°)] ( P<0.05), and the KT-2000 test showed that the disparity between the affected and healthy sides were 2.5 (1.2, 4.2) mm and 1.2 (0.8, 3.4) mm, respectively, significantly smaller than the preoperative value [7.1 (5.2, 11.2) mm] ( P<0.05). At postoperative 3 and 12 months, the VAS pain scores were significantly decreased and the knee Lysholm scores were significantly improved compared with the preoperative values ( P<0.05). Conclusion:In the treatment of avulsion fracture of the ACL tibial insertion in adults, arthroscopic suture half-tie combined with Versalok anchor fixation is a minimally invasive, reliable, and straightforward technique, leading to excellent early clinical outcomes.

The adipose tissue of mammals represents an important energy-storing and endocrine organ, and its dysfunction is relevant to the onset of several health problems, including non-alcoholic fatty liver disease (NAFLD). However, whether treatments targeting adipose dysfunction could alleviate NAFLD has not been well-studied. Adrenomedullin 2 (ADM2), belonging to the CGRP superfamily, is a protective peptide that has been shown to inhibit adipose dysfunction. To investigate the adipose tissue-specific effects of ADM2 on NAFLD, adipose-specific ADM2-overexpressing transgenic (aADM2-tg) mice were developed. When fed a high-fat diet, aADM2-tg mice displayed decreased hepatic triglyceride accumulation compared to wild-type mice, which was attributable to the inhibition of hepatic de novo lipogenesis. Results from lipidomics studies showed that ADM2 decreased ceramide levels in adipocytes through the upregulation of ACER2, which catalyzes ceramide catabolism. Mechanically, activation of adipocyte HIF2α was required for ADM2 to promote ACER2-dependent adipose ceramide catabolism as well as to decrease hepatic lipid accumulation. This study highlights the role of ADM2 and adipose-derived ceramide in NAFLD and suggests that its therapeutic targeting could alleviate disease symptoms.

Objective:To explore the risk factors of severe acute kidney injury (AKI) in septic patients, and to establish an hour-specific prediction model.Methods:Based on the information of septic patients in the Medical Information Mart for Intensive Care-Ⅳ (MIMIC-Ⅳ) database, general information, comorbidities, vital signs, severity scoring system, laboratory indicators, invasive operations and medication use were recorded. The enrolled patients were randomized into a training set and a validation set according to a ratio of 7∶3. AKI was diagnosed according to the guidelines of Kidney Disease: Improving Global Outcome (KDIGO). Based on Lasso regression and Cox regression, the risk factors of severe AKI (AKI stage 2 and stage 3) in septic patients were analyzed and hour-specific prediction model were established. Consistency index (C-index), area under the receiver operator characteristic curve (AUC) and calibration curve were used to assess the predictive efficacy of the model.Results:A total of 20 551 septic patients were enrolled, including 14 385 patients in the training set and 6 166 patients in the validation set. Multivariate Cox regression analysis showed that atrial fibrillation [hazard ratio ( HR) = 1.266, 95% confidence interval (95% CI) was 1.150-1.393], heart failure ( HR = 1.348, 95% CI was 1.217-1.493), respiratory failure ( HR = 1.565, 95% CI was 1.428-1.715), heart rate ( HR = 1.004, 95% CI was 1.002-1.007), mean arterial pressure ( HR = 1.245, 95% CI was 1.126-1.377), lactic acid ( HR = 1.051, 95% CI was 1.025-1.077), simplified acute physiology score Ⅱ (SAPSⅡ, HR = 1.019, 95% CI was 1.016-1.023), serum creatinine ( HR = 1.171, 95% CI was 1.127-1.216), anion gap ( HR = 1.024, 95% CI was 1.010-1.038), serum potassium ( HR = 1.155, 95% CI was 1.079-1.236), white blood cell count ( HR = 1.006, 95% CI was 1.003-1.009) and furosemide use ( HR = 0.414, 95% CI was 0.368-0.467) were independently associated with severe AKI in septic patients (all P < 0.01). The above predictors were applied to construct an hour-specific prediction model for the occurrence of severe AKI in septic patients. The C-index of the prediction model was 0.723 and 0.735 in the training and validation sets, respectively. The AUC for the occurrence of severe AKI at 12, 24, and 48 hours were 0.795 (95% CI was 0.782-0.808), 0.792 (95% CI was 0.780-0.805), and 0.775 (95% CI was 0.762-0.788) in the training set, and the AUC were 0.803 (95% CI was 0.784-0.823), 0.791 (95% CI was 0.772-0.810), and 0.773 (95% CI was 0.752-0.793) in the validation set, respectively. The calibration curves of the two cohorts were in good agreement. Conclusion:The hour-specific prediction model effectively identifies high-risk septic patients for developing severe AKI within 48 hours, aiding clinicians in stratifying patients for early therapeutic interventions to improve outcomes.

Objective To evaluate the efficacy and safety of brexpiprazole in treating acute schizophrenia.Methods Patients with schizophrenia were randomly divided into treatment group and control group.The treatment group was given brexpiprozole 2-4 mg·d-1 orally and the control group was given aripiprazole 10-20 mg·d-1orally,both were treated for 6 weeks.Clinical efficacy of the two groups,the response rate at endpoint,the changes from baseline to endpoint of Positive and Negative Syndrome Scale(PANSS),Clinical Global Impression-Improvement(CGI-S),Personal and Social Performance scale(PSP),PANSS Positive syndrome subscale,PANSS negative syndrome subscale were compared.The incidence of treatment-related adverse events in two groups were compared.Results There were 184 patients in treatment group and 186 patients in control group.After treatment,the response rates of treatment group and control group were 79.50％(140 cases/184 cases)and 82.40％(150 cases/186 cases),the scores of CGI-I of treatment group and control group were(2.00±1.20)and(1.90±1.01),with no significant difference(all P＞0.05).From baseline to Week 6,the mean change of PANSS total score wese(-30.70±16.96)points in treatment group and(-32.20±17.00)points in control group,with no significant difference(P＞0.05).The changes of CGI-S scores in treatment group and control group were(-2.00±1.27)and(-1.90±1.22)points,PSP scores were(18.80±14.77)and(19.20±14.55)points,PANSS positive syndrome scores were(-10.30±5.93)and(-10.80±5.81)points,PANSS negative syndrome scores were(-6.80±5.98)and(-7.30±5.15)points,with no significant difference(P＞0.05).There was no significant difference in the incidence of treatment-related adverse events between the two group(69.00％vs.64.50％,P＞0.05).Conclusion The non-inferiority of Brexpiprazole to aripiprazole was established,with comparable efficacy and acceptability.

Objectives:To verify the reliability and validity of the frailty assessment scale for elderly patients with inguinal hernia and to evaluate the value of its clinical application.Methods:A convenience sampling method was used to collect 129 geriatric patients who underwent inguinal hernia surgery from January 2018 to January 2023 in nine hospitals in Liaoning Province. There were 120 males and 9 females, of whom 89 patients were 60 to <75 years old, 33 patients were 75 to <85 years old and 7 patients were ≥85 years old. The 129 patients included 11 elderly patients with inguinal hernia who had recovered from preoperative infection with COVID-19. Statistical methods such as Cronbach′s coefficient, Kaiser-Meyer-Olkin test, Bartlett′s test, Pearson′s correlation analysis, etc. were calculated to verify the reliability indexes such as feasibility, content validity, structural validity, criterion-related validity, internal consistency reliability, and re-test reliability. Taking the 5-item modified frailty index (5-mFI) as the gold standard, the area under the curve was used to analyze the ability of the two scales to predict the occurrence of postoperative acute urinary retention, postoperative delirium, poor incision healing, operative hematoma seroma, and postoperative complications.Results:The frailty assessment scale for elderly patients with inguinal hernia showed good reliability and validity (valid completion rate of 99.2%; item content validity index of 1.000, and the scale content validity index of 1.000; exploratory factor analysis extracted a total of 1 principal component, and factor loadings of each item of 0.565 to 0.873; the AUC for frailty diagnosis using 5-mFI as the gold standard of 0.795 ( P<0.01) Cronbach′s coefficient of 0.916, retest reliability coefficient of 0.926), it could effectively predict postoperative acute urinary retention, delirium, hematoma seroma in the operative area and total complications (AUC of 0.746, 0.870, 0.806, and 0.738, respectively; all P<0.05), and prediction efficiency was higher than that of 5-mFI (AUC of 0.694, 0.838, 0.626 and 0.641, P<0.05 for delirium only), but both scales were inaccurate in predicting poor incision healing (AUC of 0.519, P=0.913 for the frailty assessment scale and 0.455, P=0.791 for the 5-mFI). Conclusions:The frailty assessment scale for elderly patients with inguinal hernia is reliable and significantly predicts the occurrence of postoperative adverse events in elderly inguinal hernia patients. The scale can also be used for preoperative frailty assessment in elderly patients with inguinal hernia after rehabilitation from COVID-19 infection.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

COVID-19 has been prevalent for three years. The virulence of SARS-CoV-2 is weaken as it mutates continuously. However, elderly patients, especially those with underlying diseases, are still at high risk of developing severe infections. With the continuous study of the molecular structure and pathogenic mechanism of SARS-CoV-2, antiviral drugs for COVID-19 have been successively marketed, and these anti-SARS-CoV-2 drugs can effectively reduce the severe rate and mortality of elderly patients. This article reviews the mechanism, clinical medication regimens, drug interactions and adverse reactions of five small molecule antiviral drugs currently approved for marketing in China, so as to provide advice for the clinical rational use of anti-SARS-CoV-2 in the elderly.
