Objective To investigate the effect of blood flow restriction combined with low-intensity plyometric jump training(LI-PJT+BFR)on lower limb dynamic postural control of functional ankle instability(FAI)in college students. Methods From March to May,2023,40 FAI college students were recruited from Xi'an Physical Education University,and randomly divided into high-intensity plyometric jump training(HI-PJT,n = 14)group,low-intensity plyomet-ric jump training(LI-PJT,n = 13)group and LI-PJT+BFR group(n = 13).All the groups finished the six-week corresponding training.The maximum voluntary isometric contraction(MVIC)of tibialis anterior,peroneus lon-gus,lateral head of gastrocnemius,gluteus maximus,vastus lateralis,biceps femoris and semitendinosus were measured,and the root mean square(RMS)of electromyography of these muscles was measured during the sin-gle-leg landing(SLL),using wireless surface electromyography before and after intervention.Moreover,they were assessed with Y-balance test and Cumberland Ankle Instability Tool(CAIT). Results MVIC and RMS of the target muscles improved after intervention in all the groups(t>2.218,P<0.05),except MVIC and RMS of peroneus longus,gluteus maximus,biceps femoris and semitendinosus in LI-PJT group,and RMS of peroneus longus in LI-PJT+BFR group;and MVIC and RMS of the target muscles were the least in LI-PJT group(F>3.262,P<0.05),except those of peroneus longus.The extension scores of Y-balance test and the total score improved after intervention(t>2.485,P<0.05),and they were the least in LI-PJT group(F>5.042,P<0.05).The CAIT score improved after intervention(t>5.227,P<0.001),and it was the least in LI-PJT group(F = 4.640,P<0.05). Conclusion LI-PJT+BFR could improve lower limb dynamic postural control of FAI college students,which is similar to HI-PJT.

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.

ObjectiveTo explore the effect of hip neuromuscular training on reducing the risk of anterior cruciate ligament (ACL) injury in female soccer players. MethodsFrom March to May, 2022, 39 female soccer players from Xi'an Physical Education University were randomly divided into control group (n = 19) and experimental group (n = 20). On the basis of daily training, the control group received sham intervention, and the experimental group received hip neuromuscular training, for six weeks. Before and after training, they were measured dynamic knee valgus (DKV) angle and assessed with Landing Error Score System (LESS); while they were also measured the maximal voluntary isometric contraction (MVIC) and root mean square (RMS) of electromyography as single leg landing of gluteus medius and gluteus maximus. ResultsAll the indexes varied little after training in the control group (|t| < 1.178, P > 0.05), while the indexes improved in the experimental group (|t| > 2.288, P < 0.05), except sagittal score of LESS; and all the indexes improved more in the experimental group than in the control group (|t| > 2.609, P < 0.05), except sagittal score of LESS and MVIC of gluteus maximus. ConclusionHip neuromuscular training can reduce the risk of ACL injury in female soccer players.

Objective To investigate the effect of XMD17-109 on the viability of glioma cells and its molecular mechanism based on extracellular signal-regulated kinase 5(ERK5)/inositol 1,4,5-trisphosphate receptor-interacting protein(ITPRIP)signaling pathway.Methods U251 glioma cells were routinely cul-tured,and ERK5 activity was inhibited by XMD17-109.ERK5 knockdown and ERK5 overexpression models were constructed by transfection of RNA fragments and plasmids,respectively.Cells were divided divided into the XMD17-109 group,the Control group,the siERK5 group,the siNC group,siERK5-OE group,the Vector group,the ERK5-OE+XMD17-109 group and the Vector+XMD17-109 group.The cell viability was detected by CCK-8,scratch and flow cytometry experiments and so on.The mRNA and protein expression levels of ERK5 and ITPRIP were detected by reverse transcription-quantitative real time PCR(RT-qPCR)and West-ern blot.Results Compared with the Control group,the cell viability of the XMD17-109 group decreased,and the expression level of ITPRIP decreased(P＜0.05).Compared with the siNC group,the cell viability of the siERK5 group was decreased,and the expression level of ITPRIP was decreased(P＜0.05).Compared with the Vector group,the cell viability of the ERK5-OE group was enhanced,and the expression level of ITPRIP was increased(P＜0.05).Compared the with Vector+XMD17-109 group,the cell viability of the ERK5-OE+XMD17-109 group was enhanced,and the expression level of ITPRIP was increased(P＜0.05).Conclusion XMD17-109 can inhibit the viability of glioma cells by inhibiting ERK5/ITPRIP signaling pathway,which is expected to be a potential drug for glioma treatment.

TORCH, which is considered as a series of pathogens, including the Toxoplasma gondii, Rubella virus, Cytomegalovirus or Herpes simplex virus, often infects the pregnant women to induce the the fetus or newborn infection by transplacental infection or exposure to contaminated genital tract secretions at delivery. Increasing evidence have been confirmed that the infection of TORCH may cause the miscarriage, premature birth, malformed fetus, stillbirth, intrauterine growth retardation, neonatal multiple organ dysfunction and other adverse pregnancy outcomes. For most TORCH-infections cases may lacking the effective treatments during pregnancy, and it is important to achieve the effacing monitoring of TORCH infections before and during pregnancy. The laboratory testing of TORCH has the great significance. However, the consensus opinions still need to improve the the standardization of TORCH testing process and the correct interpretation. Based on the characteristics of the TORCH detection method, this article gives a consensus opinion on the standardized detection and clinical application of TORCH from the laboratory perspective according to the characteristics and types of infection of different pathogens.

Objective:To observe the efficacy of benefiting Qi for warming Yang and activating blood circulation for inducing diu-resis method in the treatment of patients with chronic heart failure( CHF) and its effect on the expression of circulating miRNAs ( miR-423-5p, miR-210-3p). Methods:Totally 80 CHF patients were randomly divided into two groups,the control group with 40 patients was treated with the conventional anti-heart failure therapy, and the treatment group with 40 patients was treated with benefiting Qi for warming Yang and activating blood circulation for inducing diuresis decoction on the basis of the control group, and the treatment course was 2 weeks. The clinical efficacy and syndrome integral of traditional Chinese medicine ( TCM) were evaluated. Left ventricular ejec-tion fraction ( LVEF) and left ventricular end diastolic diameter( LVEDD) were measured by echocardiography;the plasma expression levels of circulating miRNAs(miR-423-5p, miR-210-3p) were measured by real-time PCR in the two groups before and after the treat-ment. The adverse drug reactions were observed as well. Results:The total clinical effective rate of the treatment group was significant-ly higher than that of the control group (87. 50% vs 65. 00%, P <0. 05); the syndrome integral of TCM, indices of LVEF and LVEDD and the expression of circulating miRNAs were improved in both groups(P<0. 05);the total clinical effective rate, syndrome integral of TCM, indices of LVEF and LVEDD and the expression of circulating miR-423-5p of the treatment group were better than those of the control group(P<0. 05); there was no significant difference in adverse drug reactions between the groups (P>0. 05). Conclusion:The benefiting Qi for warming Yang and activating blood circulation for inducing diuresis method can improve the clinical effects in the treatment of CHF, and improve the expression of circulating miRNAs.

OBJECTIVE:To optimize the drug placement in the automated drug dispensing machine to improve work efficien-cy. METHODS:Based on the principle of the minimum time algorithm,the drug which would be used at a high frequency was placed in the drug storage tank nearest to the drug outlet. Meanwhile,the rule of drug use was drawn from the information on a large number of prescriptions,based on which the drugs correlated with each other were placed in the drug storage tanks that were adjacent. With daily time it takes to add drugs,average time it takes to make up a prescription and the maximum number of drugs stored as the evaluated indexes,the initial drug placement in the automated drug dispensing machine was optimized. The changes in the indexes within 3 months before and after the above-mentioned optimization were statically analyzed. RESULTS:After calculat-ing the three-dimensional sizes of the packages of drugs and the dispensing frequency data of the previous year,354 drugs were se-lected and placed in the nearer or farther storage tanks in the automated dispensing machine according to the dispensing frequency and the correlation among them. After the optimization of the placement,daily time it takes to add drugs reduced by 54 min(218 vs. 165 min)on average,average time it takes to make up a prescription reduced by 8 s(24 vs.16 s)and the maximum number of drugs stored increased by 1 333 boxes(13 113 vs. 14 446 boxes)on average. There was statistical significance in differences(P<0.05). CONCLUSIONS:The initial drug placement in the automated drug dispensing machine that was optimized by minimum time algorithm has reduced daily time it takes to add drugs and average time it takes to make up a prescription and increased the maximum number of drugs stored and thus improved work efficiency.

Objective:To observe the protective effect of Yulangsan polysaccharide ( YLSP) on liver injury induced by cyclophos-phamide(CTX) in mice. Methods:Liver injury induced by CTX in mice was used as the animal model and the mice were randomly di-vided into the normal group, CTX model group, biphenyldicarboxylate ( BPDC) group, YLSP group respectively with high, medium and low dose. Except the normal group, the other groups were injected with CTX, i. p. , for 7 days to make the model. Then the ani-mals in the YLSP groups were intragastrically administered with YLSP for 7 days. The activities of alanine aminotransferase( ALT) , as-partate aminotransferase( AST) in serum, malondialdehyde( MDA) , superoxide dismutase( SOD) , glutathione( GSH) and glutathione peroxidase ( GSH-Px) in liver tissue were investigated. Hematoxylin and eosin ( HE) stain was used to study the changes in hepatic tissue of the pathological mice. Results:Compared with the model group, YLSP could obviously reduce the activities of ALT, AST and the content of MDA, and increase the content of GSH, SOD and GSH-Px (P<0. 05 or P<0. 01). HE staining showed that YLSP had significant protective effect on liver injury induced by CTX. Conclusion:YLSP has protective effect on liver injury induced by CTX.

Protamines are a group of highly basic proteins first discovered in spermatozoon that allow for denser packaging of DNA than histones and will result in down-regulation of gene transcription[1].It is well recognized that the Autographa californica multicapsid nucleopolyhedrovirus (AcMNPV) encodes P6.9,a protamine-like protein that forms the viral subnucleosome through binding to the viral genome[29].Previous research demonstrates that P6.9 is essential for viral nucleocapsid assembly,while it has no influence on viral genome replication[31].In the present study,the role of P6.9 in viral gene transcription regulation is characterized.In contrast to protamines or other protamine-like proteins that usually down-regulate gene transcription,P6.9 appears to up-regulate viral gene transcription at 12-24 hours post infection (hpi),whereas it is non-essential for the basal level of viral gene transcription.Fluorescence microscopy reveals the P6.9's co-localization with DNA is temporally and spatially synchronized with P6.9's impact on viral gene transcription,indicating the P6.9-DNA association contributes to transcription regulation.Chromatin fractionation assay further reveals an unexpected co-existence of P6.9 and host RNA polymerase Ⅱ in the same transcriptionally active chromatin fraction at 24 hpi,which may probably contribute to viral gene transcription up-regulation in the late infection phase.

Fibroblast growth factor (FGF) is a key regulator of developmental processes. A FGF homolog (vFGF) is found in all lepidopteran baculoviruses. Autographa californica nucleopolyhedrovirus (AcMNPV) and Bombyx mori NPV (BmNPV) vFGFs are chemotactic factors. Here we analyzed the vfgf of Helicoverpa armigera NPV (HearNPV), a group Ⅱ NPV. The HearNPV vfgftranscripts were detected from 18 to 96 h post-infection (hpi) of Hz-AMI cells with HearNPV and encoded a 36 kDa protein, which was secreted into the culture medium. HearNPV vFGF had strong affinity to heparin, a property important for FGF signaling via an FGF receptor. Unlike its AcMNPV homolog, HearNPV vFGF specially chemoattracted Hz-AM 1, but not other insect cells such as Sf9 and Se-UCR and not the mammalian cells 293 and HepG2. HearNPV vFGF is also associated with the envelope of BV but is absent in occlusion-derived virus, which coordinated to the chemotatic activity analysis.
