Objective To investigate the noninvasive indicators of indications for antiviral therapy in HBeAg-negative chronic hepatitis B virus (HBV) infection patients with alanine aminotransferase (ALT) ≤40 U/L under the guidance of liver pathology. MethodsA retrospective analysis was performed for the clinical data of 377 HBeAg-negative chronic HBV infection patients with ALT ≤40 U/L who were hospitalized in Affiliated Hospital of Yan’an University, from October 2013 to August 2018 and underwent liver biopsy, among whom the patients with inflammatory activity ＜A2 and fibrosis stage ＜F2 were enrolled as non-antiviral therapy group(n=266), and the patients with inflammatory activity ≥A2 or fibrosis stage ≥F2 were enrolled as antiviral therapy group(n=111). The chi-square test was used for comparison of categorical data between two groups; the t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; univariate and multivariate binary logistic regression analyses were used to screen out the influencing factors for the initiation of antiviral therapy; the receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic efficiency of each indicator in determining the need for antiviral therapy in HBeAg-negative chronic HBV infection patients with ALT ≤40 U/L. ResultsOf all 377 patients, 266 (70.6%) did not need antiviral therapy for the time being, and 111 (29.4%) had marked liver damage and thus needed active antiviral therapy. The multivariate analysis showed that liver stiffness measurement (LSM) (odds ratio ［HR］=2.003, 95% confidence interval ［CI］: 1.647-2.437, P＜005), HBsAg (HR=1.563, 95% CI: 1.110-2.200, P＜0.05), HBV DNA (HR=1.519, 95% CI: 1173-1.966, P＜0.05), and albumin (HR=0.939, 95% CI: 0.884-0.998, P＜0.05) were independent influencing factors for the initiation of antiviral therapy. The ROC curve analysis showed that the area under the ROC curve (AUC) was 0.749 (95% CI: 0.699-0799) for LSM, 0642 (95% CI: 0.586-0.699) for HBV DNA, and 0.565 (95% CI: 0.507-0.623) for HBsAg, and the combination of LSM, HBV DNA, and HBsAg had a larger AUC of 0.779 (95% CI: 0.732-0.827). ConclusionThe levels of LSM, HBV DNA, and HBsAg have a reference value in determining the initiation of antiviral therapy in HBeAg-negative chronic HBV infection patients with ALT≤40 U/L.

Objective To establish the drug use evaluation(DUE)standard of fibrinogenase for injection and provide a reference for the rational clinical application of fibrinogenase for injection.Methods Based on the specification of fibrinogenase for injection,the DUE standard was established from three aspects:drug indication,drug process and drug results,with reference to relevant guidelines and literature,and through discussion with clinical experts.A retrospective survey was conducted to evaluate the inpatients using fibrinogenase for injection from January 2021 to December 2021 in Ningde Hospital of Traditional Chinese Medicine,Fujian Province.Results A total of 256 patients were included,with a medication reasonable rate of 61.72％.The irrational use of drugs was mainly including the inappropriate usage and dosage(3.91％),off-label medication(1.95％),no skin test(8.98％),too long or inadequate course of medication(25.00％).Conclusion The DUE standard established of fibrinogenase for injection is scientific,practical and feasible.The use of fibrinogenase for injection in contraindications and high blood coagulation state,and off-label medication can be further optimized.

OBJECTIVE To compare the efficacy and safety of Saccharomyces boulardii and Bifidobacterium triple live bacteria in the treatment of pediatric diarrhea. METHODS Retrieved from PubMed， Embase， the Cochrane Library， CBM， Wanfang data， CNKI and VIP， randomized controlled trials （RCTs） about S. boulardii （S. boulardii group） versus Bifidobacterium triple liver bacteria （Bifidobacterium group） were collected. After screening the literature， extracting data and evaluating the quality， meta-analysis was performed by using RevMan 5.3 software. RESULTS A total of 9 RCTs were included， involving 898 patients. Results of meta-analysis showed there was no statistical significance in total response rate [OR＝1.69， 95%CI （0.93， 3.09）， P＝0.09]， duration of diarrhea [MD＝－1.39， 95%CI （－3.35， 0.57）， P＝0.16]， the time of abdominal pain disappearance [MD＝0.09， 95%CI（－0.87， 1.05），P＝0.86] or the incidence of adverse reactions [OR＝0.65， 95%CI （0.05， 8.03）， P＝0.74]. The number of stools in S. boulardii group was significantly less than Bifidobacterium group [MD＝－0.91， 95%CI （－1.80， －0.02）， P＝0.04]. The results of subgroup analysis showed that the duration of diarrhea in children with antibiotic-associated diarrhea in S. boulardii group was significantly shorter than Bifidobacterium group （P＜0.05）. CONCLUSIONS The efficacy and safety of S. boulardii are similar to those of Bifidobacterium in the treatment of diarrhea， but S. boulardii is better than Bifidobacterium in terms of stool number， the duration of diarrhea in children with antibiotic-associated diarrhea.

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.
