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 mechanism of long non-coding RNA RP11-79H23.3 in the development and progression of prostate cancer.Methods:The lnCAR database was used to analyze the RP11-79H23.3 content in prostate cancer tissues and adjacent tissues. RP11-79H23.3 content in prostate cancer cell lines C4-2B, LNCaP, DU-145, and 22Rv1 was detected by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR). Taking 22Rv1 as the research target, colony formation experiments and scratch experiments were used to detect the effects of overexpression of RP11-79H23.3 on the proliferation and migration of 22Rv1 cells. The LncRNome and lncACTdb databases were used to predict the downstream gene and binding sequences of RP11-79H23.3. The Cancer Genome Atlas (TCGA) database was used to analyze the correlation between RP11-79H23.3 and miR-410 expression in prostate cancer tissues. The binding of RP11-79H23.3 and miR-410 was confirmed by dual-luciferase reporter gene experiment. The effect of RP11-79H23.3 on the expression of miR-410 was detected by RT-qPCR. Western blotting was used to detect the effect of RP11-79H23.3 on the expression of phosphatase and tensin homolog/protein kinase B/mammalian target of rapamycin (PTEN/AKT/mTOR) signaling pathway proteins in 22Rv1 cells. The measurement data were expressed as mean ± standard deviation ( ± s), paired sample t-test was used for comparison between two groups, and one-way analysis of variance was used for comparison between multiple groups. Results:Compared with adjacent tissues, RP11-79H23.3 was lowly expressed in prostate cancer tissues ( P<0.01). Compared with normal prostate epithelial cells RWPE-1, RP11-79H23.3 was lowly expressed in prostate cancer cell lines C4-2B, LNCaP, DU-145, and 22Rv1 ( P<0.05). The expression of RP11-79H23.3 in 22Rv1 cells in the control group and RP11-79H23.3 group were 1.02 ± 0.30 and 8.94±1.95, respectively. 22Rv1 cells were successfully overexpressed RP11-79H23.3 compared with the control group ( t=4.04, P<0.01). The number of 22Rv1 cell clones in the control group and RP11-79H23.3 group were 166.10 ± 18.35 and 35.03±6.98, respectively. Overexpression of RP11-79H23.3 could inhibit the proliferation of 22Rv1 cells compared with the control group ( t=6.67, P<0.01). The migration rates of 22Rv1 cells in the control group and RP11-79H23.3 group were (67.40 ± 6.29)% and (26.42 ± 6.24)%, respectively. Overexpression of RP11-79H23.3 could inhibit the migration of 22Rv1 cells compared with the control group ( t=5.71, P<0.01) .Dual-luciferase reporter gene experiment showed that RP11-79H23.3 directly binds to miR-410 ( t=6.20, P<0.01). The expression of miR-410 in 22Rv1 cells in the control group and RP11-79H23.3 group were 6.22±1.39 and 1.05±0.23, respectively. RP11-79H23.3 could inhibit the expression of miR-410 in 22Rv1 cells compared with the control group ( t=3.68, P<0.01). At the same time, RP11-79H23.3 can inhibit the transduction of the PTEN/AKT/mTOR signaling pathway in 22Rv1 cells. Conclusion:RP11-79H23.3 blocks the PTEN/AKT/mTOR signaling pathway by inhibiting the expression of miR-410, thereby inhibiting the proliferation and migration of prostate cancer 22Rv1 cells.

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.

Objetive： To investigate the mechanism of antidepressant effect of verbascoside based on high-throughput sequencing technology （RNA-Seq），and to explore the possible targets and signaling pathways. MethodsForty C57BL/6 mice were randomly divided into control group，model group，fluoxetine group and verbascoside group，10 mice in each group. Except for the control group，all the other three groups were constructed with chronic unpredictable mild stimulation （CUMS） combined with solitary feeding for four weeks. Control group，fluoxetine group and verbascoside group were administered by gavage once daily for three weeks during the second week of modeling. The mice were assessed by sugar-water preference test，forced swimming test，open field test，elevated cross maze test，and water maze test. Enzyme linked immunosorbent assay（ELISA） was performed to detect the levels of major neurotransmitters and inflammatory factors in mice serum，and mRNA high-throughput sequencing was performed in the nucleus accumben and colon to screen differentially expressed genes and perform pathway enrichment analysis. Real-time polymerase chain reaction（Real-time PCR） was used to detect the mRNA expression of Gad，Slc32a1（VGAT） and brain-derived neurotrophic factor (BDNF） in nucleus accumbens. ResultCompared with the control group，the anxiety and depression-like behaviors in the model group increased，while the learning and memory ability decreased significantly. The content of neurotransmitter in serum decreased significantly. The content of pro-inflammatory factors increased significantly. The mRNA expression of Gad and Slc32a1（VGAT） in nucleus accumbens decreased significantly，while that of BDNF increased significantly. Compared with the model group，the anxiety and depression-like behavior of mice in verbascoside group was significantly relieved. The neurotransmitter content increased significantly，and the pro-inflammatory factors decreased significantly. The mRNA expression of Gad and Slc32a1（VGAT） in nucleus accumbens increased significantly，while that of BDNF decreased significantly.A total of 48 differentially expressed genes in nucleus accumbens and 43 differentially expressed genes in colon were screened by high-throughput sequencing. Differential genes in nucleus accumbens mainly focus on neuroactive ligand-receptor interaction， γ-aminobutyric acid（GABA）ergic synapse，synaptic vesicle cycle and other pathways. Colonic differential genes are mainly concentrated in GABAergic synapses，synaptic vesicle circulation，cyclic adenosine monophosphate（cAMP） signal pathway and other signal pathways. Compared with the control group，the mRNA expression of Gad and Slc32a1（VGAT） in nucleus accumbens of model group decreased significantly，while the mRNA expression of BDNF increased significantly. ConclusionVerbascoside has significant antidepressant effects. Its antidepressant effect may be related to the increase of monoamine neurotransmitters，the decrease of pro-inflammatory factors and the restoration of neurotransmitter homeostasis by increasing GABA，and it mainly acts through the signaling pathways such as neuroactive ligand-receptor interaction，GABAergic synapses，synaptic vesicle cycle and cAMP signaling pathway.

Objective: To evaluate the efficacy of in-situ full size split liver transplantation(fSLT) for adult recipients using the living donor liver transplantation(LDLT) technique and to compare the characteristics of the left hemiliver graft (LHG) and the right hemiliver graft(RHG)transplantation. Methods: Deceased donor and recipient data of 25 consecutive cases of fSLT at Department of Hepatopancreatobiliary Surgery, Ningbo Medical Center Lihuili Hospital from March to December 2021 was retrieved and the patients divided into two groups:LHG group and RHG group. Among the 13 donors,11 were male and 2 were female,aged (M(IQR))38(19) years(range: 25 to 56 years),with height of 168(5) cm(range:160 to 175 cm) and weight of 65(9) kg(range: 50 to 75 kg). The median age of the 25 recipients was 52(14) years(range:35 to 71 years),17 were male and 8 were female,15 had primary liver cancer and 10 had benign end-stage liver disease,model for end-stage liver disease score was 10(9) points(range:7 to 23 points). Of the 25 recipients,10 recipients had previously undergone hepatobiliary surgery. The follow-up period was to January 2022. Demographic,clinicopathological,surgical outcomes and postoperative complications were evaluated and compared between the two groups. Continuous quantitative data were compared using Mann-Whitney U test. Classification data were expressed as frequencies,and were compared between groups using χ² test or Fisher exact probability method. Results: Using LDLT technique,in-situ full-left/full-right liver splitting was performed and 13 viable pairs of hemiliver grafts were harvested with acquisition time of 230(53) minutes(range:125 to 352 minutes) and blood loss of 250(100) ml(range:150 to 1 000 ml). A total of 25 hemiliver grafts(13 LHG and 12 RHG) were allocated to patients listed for liver transplantation in our center by China Organ Transplant Response System. In the LHG group(13 cases),there were more females and more patients with benign end-stage liver disease than in the RHG group(12 cases)(P<0.05). The body weight and graft weight of recipients in the LHG group were lower than that in RHG group(both P<0.05). There were no significant differences in other baseline data between the two groups(all P>0.05). The graft to recipient weight ratio(GRWR) was 1.2(0.4)%(range:0.7% to 1.9%) for 25 recipients,1.1(0.5)%(range:0.7% to 1.6%)for the LHG group and 1.3(0.5)%(range:0.9% to 1.9%)for the RHG group. There was no significant difference between the two groups (P>0.05). Sharing patterns of hepatic vessels and the common bile duct are as follows:all the trunk of middle hepatic vein were allocated to the LHG group. The proportion of celiac trunk,main portal vein and common bile duct assigned to LHG and RHG was 10∶3 (P=0.009), 9∶4 (P>0.05) and 4∶9 (P=0.027),respectively. The vena cava of 12 donors in early stage retained in LHG and that of last one was shared between LHG and RHG (P<0.01). The median cold ischemia time of 25 hemiliver grafts was 240(90) minutes(range:138 to 420 minutes). For the total of 25 fSLT,the median anhepatic phase was 50(16) minutes(range:31 to 98 minutes) and the operation time was 474(138)minutes(range:294 to 680 minutes) with blood loss of 800(640) ml(range:200 to 5 000 ml). There were no significant differences in all of operation data between two groups. In the LHG group,3 patients with GRWR≤0.8% had postoperative small-for-size syndrome which improved after treatment. Postoperative Clavien-Dindo grade≥Ⅲ complications were observed in 6 cases(24.0%),4 cases(4/13) in the LHG group and 2 cases(2/12) in the RHG group,respectively. The difference was not statistically significant. Among them,5 cases improved after re-operation and intervention,1 case in LHG group died of secondary infection 2 weeks after operation,and the mortality was 4.0%. Analysis of serious postoperative complications and death has suggested that conventional caval interposition should not be used for LHG transplantation. Conclusion: Relying on accurate donor-recipient evaluation and the apply of LDLT technique,the morbidity and mortality of in-situ fSLT in adults is acceptable.

BACKGROUND: The open reduction and internal fixation (ORIF) was a standard treatment approach for fracture at distal humerus intercondylar, whereas the optimal way before ORIF remains inconclusive. We, therefore, performed a systematic review and meta-analysis to assess the efficacy and safety of olecranon osteotomy vs. triceps-sparing approach for patients with distal humerus intercondylar fracture. METHODS: The electronic searches were systematically performed in PubMed, EmBase, Cochrane library, and Chinese National Knowledge Infrastructure from initial inception till December 2019. The primary endpoint was the incidence of excellent/good elbow function, and the secondary endpoints included Mayo elbow performance score, duration of operation, blood loss, and complications. RESULTS: Nine studies involving a total of 637 patients were selected for meta-analysis. There were no significant differences between olecranon osteotomy and triceps-sparing approach for the incidence of excellent/good elbow function (odds ratio [OR]: 1.37; 95% confidence interval [CI]: 0.69-2.75; P = 0.371), Mayo elbow performance score (weight mean difference [WMD]: 0.17; 95% CI: -2.56 to 2.89; P = 0.904), duration of operation (WMD: 4.04; 95% CI: -28.60 to 36.69; P = 0.808), blood loss (WMD: 33.61; 95% CI: -18.35 to 85.58; P = 0.205), and complications (OR: 1.93; 95% CI: 0.49-7.60; P = 0.349). Sensitivity analyses found olecranon osteotomy might be associated with higher incidence of excellent/good elbow function, longer duration of operation, greater blood loss, and higher incidence of complications as compared with triceps-sparing approach. CONCLUSIONS This study found olecranon osteotomy did not yield additional benefit on the incidence of excellent/good elbow function, while the duration of operation, blood loss, and complications in patients treated with olecranon osteotomy might be inferior than triceps-sparing approach.

This paper is to illustrate the infestation and related ecological characteristics of chigger mites on the Asian house rat (Rattus tanezumi). A total of 17,221 chigger mites were collected from 2,761 R. tanezumi rats, and then identified as 131 species and 19 genera in 2 families. Leptotrombidium deliense, the most powerful vector of scrub typhus in China, was the first major dominant species on R. tanezumi. All the dominant mite species were of an aggregated distribution among different individuals of R. tanezumi. The species composition and infestations of chiggers on R. tanezumi varied along different geographical regions, habitats and altitudes. The species-abundance distribution of the chigger mite community was successfully fitted and the theoretical curve equation was Ŝ (R)=37e–(0.28R)2. The total chigger species on R. tanezumi were estimated to be 199 species or 234 species, and this further suggested that R. tanezumi has a great potential to harbor abundant species of chigger mites. The results of the species-plot relationship indicated that the chigger mite community on R. tanezumi in Yunnan was an uneven community with very high heterogeneity. Wide geographical regions with large host samples are recommended in the investigations of chigger mites.
