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 observe the clinical efficacy of bamboo-based medicinal moxibustion for chronic fatigue syndrome (CFS), and to preliminarily explore its action mechanism. METHODS: Sixty-four patients with CFS were randomly divided into a moxibustion group (32 cases, 1 case dropped off, 1 case excluded) and an acupuncture group (32 cases, 2 cases dropped off). The patients in the moxibustion group were treated with bamboo-based medicinal moxibustion, while the patients in the acupuncture group were treated with routine acupuncture. Both groups were treated once a day, 6 days as a course of treatment with 1 day interval, for a total of 2 courses of treatment. Before treatment, 1 and 2 courses into treatment and in the follow-up of 14 days after treatment, the fatigue scale-14 (FS-14) and somatic and psychological health report (SPHERE) scores were observed in the two groups. Before and after treatment, the contents of CD⁺₃, CD⁺₄, CD⁺₈ of peripheral blood T lymphocyte subsets were measured and CD⁺₄/CD⁺₈ ratio was calculated; the clinical efficacy of the two groups was compared. RESULTS: Compared before treatment, the FS-14 and SPHERE scores in the two groups were decreased 1 and 2 courses into treatment and in the follow-up (P<0.01), and the FS-14 and SPHERE scores in the moxibustion group were lower than those in the acupuncture group (P<0.01, P<0.05). Compared before treatment, the contents of CD⁺₃, CD⁺₄ and CD⁺₄/CD⁺₈ ratio in the moxibustion group were increased after treatment (P<0.01). There was no significant difference of CD⁺₃, CD⁺₄, CD⁺₈ and CD⁺₄/CD⁺₈ ratio between before and after treatment in the acupuncture group (P>0.05). After treatment, the contents of CD⁺₃ and CD⁺₄ in the moxibustion group were higher than those in the acupuncture group (P<0.05). The total effective rate was 93.3% (28/30) in the moxibustion group, which was higher than 73.3% (22/30) in the acupuncture group (P<0.05). CONCLUSION Bamboo-based medicinal moxibustion could improve the physical and mental fatigue symptoms and psychological status in patients with CFS. Its effect may be related to regulating the contents of CD⁺₃, CD⁺₄ of peripheral blood T lymphocyte subsets and CD⁺₄/CD⁺₈ ratio.

Objective To explore the role pathway and pattern of the myeloma cancer gene (MYC) and its mRNA interaction with the microRNAs(miRNAs) and circular RNA(circRNAs) at hour 0, hour 6 and hour 72 in the rat liver regeneration. Methods The rat 2/3 hepatectomy (PH) model was prepared as described by Higgins, the hepatocytes were isolated according to the method of Smedsrod et al. The expression changes of mRNA, miRNA and circRNA [together named as competing endogenous RNA (ceRNA)] were detected by the large-scale quantitative detection technology, the interaction network of ceRNA was constructed by Cytoscape 3.2 software, and their correlation in expression and role were analyzed by ceRNA comprehensive analysis. Results It was found that at hour 0 and hour 6 after PH, the ratio value of MYC mRNA showed 0.15±0.03 and 2.36±0.20, miR-134-5p indicated 3.22±0.61 and 0.08±0.02, circRNA_12112 displayed 0.68±0.21 and 13.35±3.53. At the same time, the cell cycle initiation-related genes ras association domain family member 1 (RASSF1), cyclin dependent kinase 2 (CDK2), superoxide dismutase 2 (SOD2), which were promoted in expression by MYC, were down-regulated at hour 0 after PH, but the cell cycle initiation-related genes nestin (NES), RAD21 cohesin complex component (RAD21), CUE domain containing 2 (CUEDC2), which are inhibieted in expression by MYC, had no meaningful express changes at hour 0 after PH. On the other hand, the cell cycle initiation-related gene SOD2, which was promoted in expression by MYC, was up-regulated at hour 6 after PH, but the cell cycle initiation-related genes NES, RAD21, CUEDC2, which are inhibieted in expression by MYC, were down-regulated at hour 6 after PH. In contrary, at hour 72 after PH, the ratio value of MYC mRNA showed 2.36±0.20, miR-880-3p indicated 0.54±0.01, circRNA_09599 displayd 0.54±0.16. At the same time, the cell cycle termination-related gene hepatocyte growth factor (HGF), which is promoted in expression by MYC, was up-regulated 72 hours after PH, the cell cycle termination-related genes MET proto-oncogene receptor tyrosine kinase (MET) and cyclin dependent kinase inhibitor 1A (CDKN1A), which are inhibieted in expression by MYC, were down-regulated 72 hours after PH. Conclusion The correlation in expression and role of the miRNAs, which are inhibited by circRNAs, MYC, its mRNA is inhibited by miRNAs, and the cell cycle initiation-related and cell cycle termination-related genes, which are regulated by MYC, are helpful for the hepatocyte to be in cell cycle initiation state at hour 6 after PH and to be in cell cycle termination state at hour 72 after PH.

To explore the genetic causes of 3 male infertility patients with acephalospermia and the outcome of assisted reproductive technology. Clinical diagnosis, sperm morphology examination, sperm transmission electron microscopy examination were performed on 3 patients, and the whole exome sequencing technology was used for screening, Sanger sequencing verification, mutation pathogenicity analysis, and protein sequence homology comparison. Assisted reproductive technology was implemented to assist pregnancy treatment. The 3 patients were all sporadic infertile men, aged 25, 42 and 26 years, and there was no obvious abnormality in the general physical examination. Male external genitalia developed normally, bilateral testicles were normal in volume, and bilateral epididymis and spermatic vein were palpated without nodules, cysts, and tenderness. Repeated semen analysis showed that a large number of immature sperm could be seen, and they had the ability to move. The SUN5 gene of the 3 male infertile patients was a case of homozygous missense mutation c.7C>T (p.Arg3Trp), a case of compound heterozygous missense mutation c.1067G>A (p.Arg356His) and nonsense mutation c.216G>A (p.Trp72*) and a case of homozygous missense mutation c.1043A>T (p.Asn348Ile), of which c.7C>T (p.Arg3Trp) and c.1067G>A (p.Arg356His) were new variants that had not been reported. SIFT, Mutation Taster and PolyPhen-2 software function prediction results were all harmful, the nonsense mutation c.216G>A (p.Trp72*) led to the premature termination of peptide chain synthesis which might have a greater impact on protein function. The homology regions in the protein sequence homology alignment were all highly conserved.The 3 male patients and their spouses obtained 4 biological offspring through intracytoplasmic sperm injection, all of which were boys, and one of them was a twin.Three male infertile patients might be caused by SUN5 gene mutations. Such patients could obtain their biological offspring through assisted reproductive technology. It was still necessary to pay attention to the genetic risk of ASS, it was recommended that both men and women conduct genetic counseling and screening at the same time. In clinical diagnosis, whole exome sequencing technology could be used to perform auxiliary examinations to determine the treatment plan and assisted reproductive methods as soon as possible to reduce the burden on the family and society. The newly discovered mutation sites of SUN5 gene provided clues and directions for elucidating the pathogenic mechanism, and at the same time expanded the pathogenic mutation spectrum of ASS.

Metformin (MET), an antidiabetic agent, also has antioxidative effects in metabolic-related hypertension. This study was designed to determine whether MET has anti-hypertensive effects in salt-sensitive hypertensive rats by inhibiting oxidative stress in the hypothalamic paraventricular nucleus (PVN). Salt-sensitive rats received a high-salt (HS) diet to induce hypertension, or a normal-salt (NS) diet as control. At the same time, they received intracerebroventricular (ICV) infusion of MET or vehicle for 6 weeks. We found that HS rats had higher oxidative stress levels and mean arterial pressure (MAP) than NS rats. ICV infusion of MET attenuated MAP and reduced plasma norepinephrine levels in HS rats. It also decreased reactive oxygen species and the expression of subunits of NAD(P)H oxidase, improved the superoxide dismutase activity, reduced components of the renin-angiotensin system, and altered neurotransmitters in the PVN. Our findings suggest that central MET administration lowers MAP in salt-sensitive hypertension via attenuating oxidative stress, inhibiting the renin-angiotensin system, and restoring the balance between excitatory and inhibitory neurotransmitters in the PVN.

OBJECTIVE Regulating P2x7R- NLRP3 inflammasome activation might be a potentialtherapeutic strategy to treat alcoholic hepatosteatosis. We investigated whether this process would be modulated by gentiopicroside (GPS), which is attributed to the bitterness of gentian root extract. METHODSAn in vivo model was established by intragastrically treating mice with ethanol, and an in vitro modelwas created by treating HepG2 cells with ethanol or treating RAW 264.7 macrophages and murinebone marrow- derived macrophages (BMDMs) with lipopolysaccharides (LPS) plus adenosine triphos-phate (ATP). RESULTS In alcoholic hepatosteatotic mice model, GPS decreased serum aminotrans-ferase and triglyceride accumulation. GPS regulated sterol regulatory element-binding protein-1 (Srebp1),peroxisome proliferators- actived receptors α (PPARα) and acetyl CoA carboxylase (ACC) expressionvia elevating liver kinase B1 (LKB1)/AMP-activated Kinase (AMPK). Suppression of nucleotide-bindingoligomerization domain-like receptor protein 3 (NLRP3), caspase-1 and expression by GPS resulted inthe inhibition of interleukin-1β (IL-1β) production. In ethanol-exposed HepG2 cells, GPS reduced lipo-genesis and promoted lipid oxidation via P2x7R- NLRP3 inflammasome activation. P2x7R silencingenhanced AMPK activity, and reduced Srebp1 expression in ethanol-treated hepatocytes. GPS down-regulated P2x7R-mediated inflammatory response to extracellular ATP in LPS-primed RAW 264.7 macro-phages and BMDMs. Additionally, P2x7R deficiency attenuated IL- 1β cleavage in RAW 264.7 macro-phages, and GPS further suppressed IL-1β cleavage. CONCLUSION Activation of LKB1/AMPK signalingby GPS might be mediated by P2x7R-NLRP3 inflammasome, suggesting a therapeutic utility of P2x7Rblockade in alcoholic hepatosteatosis treatment.

OBJECTIVE The current study was designed to investigate the anti-steatosis effect of Pleurotus citrinopileatus extract (PC) and the underlying mechanism in vivo and in vitro. METHODS Acute and chronic alcoholic hepatosteatosis murine models and ethanol-treated HepG2 cells were applied. RESULTS In vitro,the anti-steatosis effect of PC was further confirmed via Nile red staining in HepG2 cells treated with ethanol.Both of acute and chronic alcohol-induced mice hepatosteatosis model,PC decreased serum aminotransferase and triglyceride accumulation. Upregulated sterol-regulatory element binding protein1(Srebp1),purinergic ligand-gated ion channel 7receptor(P2X7R)and downregulated sirtuin1 (SIRT1), adenosine 5′-monophosphate (AMP)-activated protein kinase α (AMPKα) caused by acute and chronic alcohol intake were modulated by PC.In ethanol-exposed HepG2 cells,PC reduced lipid accumulation in a concentration-dependent manner and exhibited superior ability in controlling lipid accumulation compared with metformin. CONCLUSION PC could abolish hepatic lipid accumulation through regulating SIRT1-AMPKα signaling in acute and chronic alcohol-induced hepatic steatosis.
