Objective To analyze the epidemiological characteristics of adverse events following immunization(AEFI) ofthree types of hepatitis B vaccines(CHO, Saccharomyces cerevisiae and Hansenula polymorpha) in Fujian Province from 2019to 2023, and evaluate their safety. Methods The AEFI case data and vaccination data of hepatitis B vaccines reported inFujian Province from 2019 to 2023 were collected through the Chinese Immunization Planning Information ManagementSystem. The occurrence characteristics, incidence rates and other indicators of AEFI related to hepatitis B vaccines wereanalyzed by using descriptive analysis methods. Results In Fujian Province from 2019 to 2023, there were 677 reportedcases of AEFI related to hepatitis B vaccines, with an AEFI reported incidence of 7. 44 per 100 000 doses. The male-to-female ratio was 1. 20∶1, and the age distribution was mainly in the group of less than 1 year old. The reported incidence ofcommon adverse reactions was 6. 24 per 100 000 doses, and the reported incidence of rare adverse reactions was 0. 96 per100 000 doses. Rare vaccine reaction cases were mainly anaphylactic reaction. There were statistically significant differencesin the reported incidence of common adverse reactions and allergic skin rashes among the three types of hepatitis B vaccines(χ~2= 111. 587 and 13. 284, respectively, each P < 0. 05). Conclusion The reported incidence of AEFI related to hepatitisB vaccines in Fujian Province has been rare from 2019 to 2023, falling within the expected range of WHO, indicating goodsafety of the vaccines.

Objective: To identify an optimal back-flush solution for leukocyte-depleted filters that maximizes peripheral blood mononuclear cell (PBMC) recovery with high viability, long-term storage stability, and sterility of the harvested residues, thereby providing a clinically translatable strategy. Methods: Three sterile bag-packaged solutions—Saline, Solvent, and Hanks' balanced salt solution (HBSS)—were used to back-flush randomly assigned leukocyte-depleted filters. Nucleated cell recovery rate and viability of the harvested residues were compared. The optimal solution identified was applied to an expanded sample set. PBMC viability and yield were evaluated after 1h vs 48h storage of the residues. PBMCs isolated from the residues were cryopreserved in liquid nitrogen for 1 month, followed by post-thaw comparisons of viability and T-cell expansion capacity. Results: The Solvent group achieved the highest and most consistent nucleated cell recovery rate. Post-flush recovery rate from filters after 400 mL whole blood processing was (21.3±1.6)% for the Solvent group, significantly higher than Saline group (19.2±6.3)% and HBSS group (11.2±5.0)%, with residues from all groups maintaining viability >90%. No biologically significant difference in residue viability was observed between 48h vs 1h storage groups (93.3±2.3)% vs (95.7±1.8)%). PBMC recovery rates from residues showed no statistical difference between 48h vs 1h storage groups [(48.2%±9.5%)vs (40.41%±8.35%), P>0.05], with (17.7±2.6)×10 cells. After 1-month cryopreservation and 10-day expansion, PBMCs isolated from 48-hour-stored residues retained (91.2±3.2)% viability and achieved a (61.9±15.9)-fold expansion. Conclusion: The bag-packaged Solvent, as a back-flush solution, enables sterile acquisition of leukocyte-depleted filter residues through closed-system tubing connections. These residues maintained PBMC viability and recovery rates after 48h storage at 2℃-8℃, with post-cryopreservation (1-month liquid nitrogen) viability and expansion capacity remaining stable. This protocol complies with blood bank regulatory criteria, addresses the concerns about the infectious window period in cell therapy raw materials, and provides a clinically translatable strategy for PBMC-based applications.

Objective To screen differentially expressed long non-coding RNAs (lncRNAs) in the liver of mice infected with Schistosoma japonicum during the chronic pathogenic stage and identify their functions, so as to provide insights into unravelling the role of lncRNAs in S. japonicum infection-induced liver disorders. Methods Twenty 6-week-old C57BL/6 mice were randomly divided into two groups, of 10 animals each group. Each mouse in the experimental group was infected with (15 ± 2) S. japonicum cercariae via the abdomen for modeling chronic S. japonicum infection in mice, and distilled water served as controls. All mice were sacrificed 70 days post-infection, and mouse liver specimens were sampled for RNA extraction and library construction. All libraries were sequenced on the Illumina NovaSeq 6000 sequencing platform. Data cleaning was performed using the fastp software, and reference genome alignment and gene expression (FPKM) calculation were performed using the HISAT2 software. Potential lncRNA sequences were predicted using the software CNIC, CPC, Pfam, and PLEK, and potential lncRNAs were screened. Differentially expressed lncRNAs were screened with the DESeq2 software and subjected to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses to identify biological processes and metabolic pathways involved in target genes of differentially expressed lncRNAs. Results A total of 333 potential lncRNAs were screened, and 67 were identified as differentially expressed lncRNAs, including 49 up-regulated and 18 down-regulated lncRNAs. A total of 53 target genes were predicted for differentially expressed lncRNAs. GO enrichment analysis showed that these target genes were mainly enriched in biological process and molecular function, among which Sema7a, Arrb1, and Ccl21b genes may be hub target genes for positive regulation of extracellular regulated protein kinase 1 (ERK1) and ERK2 cascades and may participate in the regulation of collagen expression. KEGG enrichment analysis showed that the target genes of differentially expressed lncRNAs were mainly enriched in cytokine-cytokine receptor interaction, viral protein interactions with cytokines and cytokine receptors, chemokine signaling pathway, and nuclear factor kappa-B (NF-κB) signaling pathway. Conclusions This study identifies differentially expressed lncRNAs and functional enrichment of their target genes in the liver of mice during the chronic pathogenic stage of S. japonicum infection. Up-regulated lncRNAs may affect biological processes of ERK1/2 cascades and chemokine signaling pathways via target genes Sema7a, Arrb1, and Ccl21b, thereby affecting collagen expression and inflammatory signal pathways, ultimately affecting the development of liver disorders.

Based on the discussions in the The Inner Canon of Yellow Emperor （《黄帝内经》）， it is proposed that in the course of the disease， "bind" represents the initial stage of pulmonary nodules， while "accumulation" represents the final form. In terms of the pathogenesis， "two colds interacting" represented by "body cold" and "cold fluid retention" are the prerequisites for the formation of pulmonary nodules， while "disorder of qi" represented by "fainting" is the core of the formation. The specific manifestation is the disturbance of pivot of shaoyang （少阳） or shaoyin （少阴）， resulting in a complex of cold and heat， and then phlegm and stasis are suddenly generated and further formed into nodules. Therefore， the treatment principle should be to regulate the cardinal mechanism， dissolve phlegm and blood stasis. Depending on the complex degree of cold and heat， it is suggested to use Chaihu Guizhi Decoction （柴胡桂枝汤）， Chaihu Guizhi Ganjiang Decoction （柴胡桂枝干姜汤）， or Chaihu Xianxiong Decoction （柴胡陷胸汤） for disturbance of shaoyang pivot， while for shaoyin pivot dysfunction， modified Mahuang Fuzi Xixin Decoction （麻黄附子细辛汤） or Shengjiang Powder （升降散） can be used.

ObjectiveTo evaluate the effect and safety of Jiuxin Pill （救心丸） on exercise tolerance and quality of life in patients with stable angina pectoris （SAP）. MethodsA randomised， double-blind， placebo-controlled， multicentre study design was used to enroll 170 patients of SAP from nine centres， which were divided into 85 patients each in the trial group and control group with 1∶1 ratio. Both groups maintained the original western medicine treatment plan， and added Jiuxin Pill or placebo respectively， 2 pills （0.05 g） each time twicely for 28 days. The main outcomes were total exercise time （TED） in the exercise treadmill test and Seattle Angina Questionnaire （SAQ） scores including physical limitation （PL）， angina stability （AS）， angina frequency （AF）， treatment satisfaction （TS）， and disease perception （DP）. The secondary outcomes were exercise treadmill test indicators including heart rate recovery in 1 min （HRR1）， metabolic equivalents （METs）， maximum magnitude of ST-segment depression， and the Borg rating of perceived exertion scale， the average number of angina attacks per week， withdrawal and reduction rate of nitroglycerin， traditional Chinese medicine syndrome scores， incidence of major adverse cardiovascular events. Safety indicators were evaluated and the occurrence of adverse events during the trial was recorded. Data was collected before treatment， day 28±2 in treatment period， and follow-up at day 56 which is 28±2 days after treatment period finished. ResultsEighty-four and eighty-five patients respectively from trial group and control group were included to the full analysis set （FAS） and safety analysis set （SS）. Compared with the group before treatment and with the control group after treatment， the trial group had higher TED， HRR1， and METs， and lower maximum magnitude of ST-segment depression and Borg rating of perceived exertion scores after treatment （P＜0.01）. Compared with the group before treatment and with the control group after treatment and at follow-up， the total SAQ score and scores of AS， AF， TS and DP of the trial group after treatment and at follow-up elevated， while the average number of angina attacks per week and traditional Chinese medicine syndrome scores reduced （P＜0.01）. There was no statistically significant difference in the withdrawal and reduction rate of nitroglycerin between groups （P＞0.05）. Major adverse cardiovascular events occurred in 1 case （1/84， 1.19%） in the trial group and 1 case （1/85， 1.18%） in the control group， and the difference between groups was not statistically significant （P＞0.05）. A total of 3 cases of adverse events occurred in the trial group （3/84， 3.57%）， and a total of 6 cases of adverse events occurred in the control group （6/85， 7.06%）， and there was no statistically significant difference in the incidence of adverse events between groups （P＞0.05）. ConclusionIn the treatment of SAP， Jiuxin Pill combined with conventional western medicine can further enhance exercise tolerance， improve quality of life， and demonstrate great safety.

Objective:To assess the occurrence, prognosis and possible early risk factors of jaundice in polytrauma patients.Methods:This study was a single-center, prospective study. Polytrauma patients (age>18 years) admitted to Tongji Trauma Center from October 2020 to January 2023 were enrolled. The patients with liver, biliary tract or pancreatic traumatic injury, previously suffered from chronic liver disease were excluded. The clinical characteristics of patients, laboratory test results, imaging examination results, Injury Severity Score (ISS), Glasgow Coma Score and APACHEⅡ score were collected. The incidence of jaundice, the classification of jaundice or the severity of jaundice after multiple injuries, the mortality rate of polytrauma patients with jaundice, and the early independent risk factors of jaundice in polytrauma were analyzed. The differences between the groups were compared by Student’s t test or χ2 test. The independent risk factors of jaundice were analyzed by Logistic regression analyzed. Results:A total of 742 polytrauma patients were included, 34.09% polytrauma patients were accompanied by jaundice, and the ratio of both moderate and severe jaundice were as high as 32.41%. The main type of jaundice was intrahepatic cholestatic jaundice (47.03%). The mortality rate of polytrauma patients accompanied by jaundice was significantly higher than that of polytrauma patients without jaundice (12.25% vs. 3.47%, P<0.001). Logistic regression analysis showed that ISS score ( OR=3.405, 95% CI: 1.962-7.438, P=0.026), plasma lactate ( OR=2.216, 95% CI: 1.203-4.862, P=0.017), interleukin-6 levels ( OR=2.431, 95% CI: 1.424-3.793, P=0.007), the overall duration of parenteral nutrition ( OR=3.011, 95% CI: 1.624-5.041, P=0.022), and the total duration of mechanical ventilation ( OR=3.572, 95% CI: 1.497-4.601, P=0.031) were the early independent risk factors for jaundice in patients after polytrauma. Conclusions:Polytrauma patients are prone to developing jaundice after injury, which is more harmful, especially for intrahepatic cholestatic jaundice after injury. Early identification and early intervention of risk factors associated with jaundice after injury should be strengthened.

Objective: This meta-analysis aims to refine the understanding of the optimal choice between different cage shapes in transforaminal lumbar interbody fusion (TLIF) by systematically comparing perioperative data, radiological outcomes, clinical results, and complications associated with banana-shaped and straight bullet cages. Methods: A meticulous literature search encompassing PubMed, Embase, Scopus, Web of Science, China Knowledge Network, and Wanfang Data was executed up to October 5, 2023. Inclusion criteria focused on studies comparing banana-shaped and straight bullet cages in TLIF. The quality of included studies was assessed using appropriate tools such as the Newcastle-Ottawa Scale (NOS) for nonrandomized studies. Rigorous evaluations were performed for radiographic outcomes, including disc height (DH), segmental lordosis (SL), lumbar lordosis (LL), subsidence, and fusion rates. Clinical outcomes were meticulously evaluated using visual analogue scale (VAS), Oswestry Disability Index (ODI), and complications. Results: The analysis incorporated 7 studies, involving 573 patients (297 with banana-shaped cages, 276 with straight cages), all with NOS ratings exceeding 5 stars. No statistically significant differences were observed in operative time, blood loss, or hospitalization between the 2 cage shapes. Banana-shaped cages exhibited greater changes in DH (p = 0.001), SL (p = 0.02), and LL (p = 0.01). Despite statistically higher changes in ODI for straight cages (26.33, p < 0.0001), the actual value remained similar to banana-shaped cages (26.15). Both cage types demonstrated similar efficacy in VAS, complication rates, subsidence, and fusion rates. Conclusion Although banana-shaped cages can excel in restoring DH, SL, and LL, straight bullet cages can provide comparable functional improvements, pain relief, and complication rates.

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.

Objective:To explore the safety and efficacy of laparoscopic right posterior sectionectomy (LRPS) in the left side lying at 60° run-hug position.Methods:The clinical data of 12 cases underwent LRPS at the Department of Biliary and Pancreatic Surgery, Sun Yat-sen Memorial Hospital, Sun Yat-sen University from August 2022 to June 2023 were analyzed. There were 9 males and 3 females, ranging in age from 26 to 76 years old. To evaluate the safety and effectiveness of the operation, operation time, intraoperative blood loss, the number and time of intraoperative hilar occlusion, postoperative drainage time, postoperative hospitalization time and postoperative complications were summarized.Results:Twelve operations were successfully completed under laparoscopy, and no patient was converted to laparotomy due to the difficulty in controlling intraoperative bleeding. 12 patients included 1 case of intrahepatic bile duct stones, 5 cases of primary liver cancer, 2 cases of hepatic hemangioma, 2 cases of focal nodular hyperplasia of the liver, 1 case of metastatic liver cancer, and 1 case of liver abscess. Operation time was (246.2±90.4) min, and the intraoperative blood loss was 125(22, 275) ml. The number of intraoperative hilar occlusion was 2.00(0.25, 2.75), and intraoperative hilar occlusion time was (27±22) min. Postoperative drainage time was (5.0±2.6) d, and the length of postoperative hospital stay was 6.0(4.3, 8.0) d. Intraoperative blood transfusion occurred in 1 patient, and postoperative abdominal effusion occurred in 1 patient. There was no postoperative death. All patients were recovered and discharged successfully.Conclusion:LRPS is safe and effective for the lesions in the right posterior hepatic region with the left side lying at 60° run-hug position.
