Objectives To explore the feasibility of temporary veno-venous extracorporeal membrane oxygenation(VV-ECMO)technology for early on-site treatment,through establishing an animal model of severe blast lung injury in goats by free-field chemical explosion experiments in high-altitude regions.Methods A total of 16 adult goats were selected,and divided into the control group and the treatment group according to the random number table method,with 8 goats in each group.A model of severe blast lung injury was established at an altitude of 4 600 meters above sea level,then the goats in the control group were given respiratory support and the goats in the treatment group were given temporary VV-ECMO treatment.The survival status of the goats 15 minutes after injury was recorded,the vital signs[including body temperature,respiration rate,heart rate,and mean arterial pressure(MAP)]and arterial blood gas analysis indicators[including pH,arterial partial pressure of oxygen(PO2),arterial partial pressure of carbon dioxide(PCO2),oxygen saturation(SaO2),lactate(LAC),calcium(Ca2+),hematocrit(HCT),and hemoglobin(Hb)]before injury and 1 hour,2 hours,3 hours after injury were compared in the two groups.The post-mortem examination was performed on all dead goats and sacrificed goats after treatment,the severity of lung injury was assessed by organ injury scaling(OIS),and the lung injury score was evaluated by abbreviated injury scale(AIS).The wet-to-dry weight ratio(W/D)and lung coefficient were calculated.Results Within 15 minutes after the explosion,4 goats in the control group died and 4 goats survived;and 5 goats in the treatment group died and 3 goats survived.There was no statistically significant difference in the body temperature,respiration rate,heart rate,or MAP before and after injury between the two groups(P>0.05).The PaO2 and SaO2 1 hour,2 hours,and 3 hours after injury in the treatment group were superior than those in the control group(P<0.05),the Ca2+ 2 hours after injury was significantly higher than that in the control group(P<0.05),and there was no statistically significant difference in the pH,PCO2,LAC,HCT or Hb at different time points after injury between the two groups(P>0.05).There was no statistically significant difference in the OIS,AIS or lung coefficient between the two groups(P>0.05),but the W/D of the lung tissue in the control group was lower than that in the treatment group(P<0.05).Conclusion We have established a novel,feasible,and stable treatment effect temporary VV-ECMO animal treatment strategy for the first time in the high-altitude regions,which can provide animal experiment evidence for the early on-site VV-ECMO treatment of severe blast lung injury in high-altitude regions.

Sialic acid-binding immunoglobulin-like lectins(Siglecs)are expressed on most white blood cells and play a key role in signal transduction of immune cells.Recent studies have shown that many bacterial pathogens regulate the host immune response through the interaction between sialic acid(Sia)and Siglecs,thereby influencing the occurrence and development of diseases.Understanding bacterial pathogenic mechanisms is essential to identify potential effective therapeutic targets and help manage bacterial infectious diseases.Herein,the structure,biological function,and research progress in Siglecs in bacterial in-fectious diseases are briefly reviewed.

The aim of this study was to investigate the impact of overexpressing 70-kD heat shock pro-teins(Hsp70)on glycolysis in C2C12 cells during myogenesis and adipogenesis.Using C2C12 cells as the research material,adenovirus was used to overexpress the Hsp70 gene,and changes in the expression of glycolytic genes were detected using fluorescence quantitative PCR and Western blotting techniques.The study indicated that during C2C12 cell myogenic differentiation,the expression trend of the Hsp70 gene was consistent with that of Gsk3β,Pkm,Prkag3,Pfkm,and Hk-2 genes,suggesting a relationship between Hsp70 and the glycolytic pathway during myogenic differentiation.Overexpression of Hsp70 in the later stages of myogenic differentiation significantly upregulated the expression of Gsk3β,Pkm,Prk-ag3,and Pfkm genes(P＜0.05),with no significant impact on Hk-2 gene expression(P＞0.05).Dur-ing C2C12 cell adipogenic induction,the expression trend of the Hsp70 gene was similar to that of Gsk3β,Pkm,Prkag3,Pfkm,and Hk-2 genes,indicating a relationship between Hsp70 and the glycolytic path-way during adipogenic induction.Following Hsp70 overexpression,in the later stages of adipogenic in-duction,the number of lipid droplets was significantly higher compared to the control group,with a sig-nificant upregulation of Gsk3β,Pkm,Prkag3,and Pfkm gene expression(P＜0.05),while Hk-2 gene expression was not significantly affected(P＞0.05).In conclusion,Hsp70 in C2C12 cells in myogenic and adipogenic states promoted the breakdown of glycogen into 6-phospho-glucose,thereby enhancing the glycolytic pathway,providing insights into the functional role of the Hsp70 gene in glycolysis in C2C12 cells.

AIM To analyze the constituents absorbed into blood and brain from Zhishe Tongluo Capsules.METHODS Sixteen rats were randomly assigned into four groups and given intragastric administration(3.1 g/kg),after which the cerebral ischemia-reperfusion injury(MACO)model was established,the blood and brain tissues were collected,and UHPLC-Q Exactive Focus MS/MS was adopted in the identification of prototype constituents.RESULTS Total 70 constituents were identified,20 of which were found in the blood,mainly including flavonoids,tanshinones and Ligusticum chuanxiong phthalides,and 7 of them could enter the brain through blood-brain barrier.Compared with the normal administration group,the MACO administration group demonstrated added constituents absorbed into blood containing 3-hydroxybenzoic acid,calycosin-7-glucoside,curcumenol,senkyunolide B,dihydrotanshinone I and cryptotanshinone;removed constituents absorbed into brain containing puerarin,elemicin,sedanolide,and added those containing salvianolic acid A,senkyunolide I,dihydrotanshinone I in the left brain tissues(infarcted side).CONCLUSION The constituents absorbed into blood and brain from Zhishe Tongluo Capsules,along with the enhanced absorptions of phthalides,quinones and phenols in MACO rats in vivo may be the active substances for treating cerebral infarction.

Objective:To explore the clinical effects of free anterolateral thigh perforator flap (ALTPF) with modified cross-leg vessel bridging in reconstruction of infected wounds in the lower leg combined with major vessel defects.Methods:A retrospective observational study was conducted on 7 patients who admitted to the Department of Trauma Orthopaedics, the 521 Hospital of Norinco Group from January 2020 to December 2021 for treatment of large infected wounds in lower leg with soft tissue defect by reconstructive surgery of flap transfer. The patients were 5 males and 2 females, aged 23-50 years old with an average age of 37 years old. The causes of injury were: 5 patients were of car accidents, 1 of machinery compression and 1 of heavy object crush. The wounds were reconstructed after debridement and infection control with sensitive antibiotics, where the soft tissue defects were found at 11.0 cm×15.0 cm to 20.0 cm×32.0 cm in size. All patients underwent vascular angiography or CDU examinations and it was confirmed that the affected calf had only an anterior tibial artery as the vessel left for blood supply in 6 patients and a posterior tibial artery as the blood supply vessel in one patient. Therefore application of vascular end-to-side anastomosis in free flap reconstruction of limb defects was impossible due to the damaged artery could not be salvaged as a blood supply artery for the transferred flap. Therefore, a modified cross-leg vessel bridging to the freed ALTPF in the affected lower leg was applied. The donor site of the pedicle was covered with VSD while the pedicle of the flap was anastomosed. It was remained until the posterior tibial artery and the tubular flap were ready for replantation after disconnection of the pedicle. The sizes of flap were 13.0 cm×17.0 cm to 22.0 cm×32.0 cm (unilateral ALTPFs for 6 patients and bilateral ALTPFs for 1 patient). Two donor sites in low tension were direct closed, and the rest of 5 donor sites that had great tensions and could not be directly sutured were reconstructed by skin grafting. The survival and complications of flaps were observed in the scheduled postoperative follow-ups at outpatient visits, WeChat reviews and home visits, etc.Results:All 7 patients were successfully treated and had 12-24 months postoperative follow-up, with an average of 16 months. All flaps survived, with primary healing in 6 patients and 1 patient had partial flap necrosis with surface infection, which healed after dressing changes. The wound healing time was 14-36 days with an average of 17.9 days. The time for disconnection of the cross-leg vessel bridging pedicle was 3-4 weeks with the flap transfer, with an average of 3.6 weeks. The donor sites of ALTPFs and vessel pedicles all healed well. CDU confirmed the patency of the contralateral posterior tibial artery. Satisfactory functional recovery was achieved in the affected lower limb and there was a good function of the contralateral healthy lower leg.Conclusion:Application of the transfer of a free ALTPF with modified cross-leg vessel bridging in reconstruction of infected wounds with major vessel defects in the lower leg has shown excellent clinical outcomes. It is a practical and effective method in treatment of large infective defect in lower leg.

This study reports on three patients with Shwachman-Diamond syndrome (SDS) who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) at the First Affiliated Hospital of Zhejiang University School of Medicine. Based on relevant literature, the clinical manifestations and genetic mutation characteristics of SDS were summarized, and the efficacy and timing of allo HSCT for such patients were explored. Three SDS patients were all male, with transplant ages of 32, 33, and 32 years old, respectively. All three patients were diagnosed in childhood. Case 1 presented with anemia as the initial clinical manifestation, which gradually progressed to a decrease in whole blood cells; Case 2 and 3 both present with a decrease in whole blood cells as the initial clinical manifestation. Case 1 and 3 have intellectual disabilities, while case 3 presents with pancreatic steatosis and chronic pancreatitis. All three patients have short stature. Three patients all detected heterozygous mutations in the SBDS: c.258+2T>C splice site. The family members of the three patients have no clinical manifestations of SDS. All three patients were treated with a reduced dose pre-treatment regimen (Fludarabine+Busulfan+Me-CCNU+Rabbit Anti-human Thymocyte Globulin). Case 1 and case 2 underwent haploid hematopoietic stem cell transplantation, while case 3 underwent unrelated donor hematopoietic stem cell transplantation. Case 1 was diagnosed with myelodysplastic syndrome transforming into acute myeloid leukemia before transplantation, but experienced early recurrence and death after transplantation; Case 2 is secondary implantation failure, dependent on platelet transfusion; Case 3 was removed from medication maintenance treatment after transplantation, and blood routine monitoring was normal.

Jumonji domain-containing protein D3(JMJD3)is a 2-oxoglutarate-dependent dioxygenase that specif-ically removes transcriptional repression marks di-and tri-methylated groups from lysine 27 on histone 3(H3K27me2/3).The erasure of these marks leads to the activation of some associated genes,thereby influencing various biological processes,such as development,differentiation,and immune response.However,comprehensive descriptions regarding the relationship between JMJD3 and inflammation are lacking.Here,we provide a comprehensive overview of JMJD3,including its structure,functions,and involvement in inflammatory pathways.In addition,we summarize the evidence supporting JMJD3's role in several inflammatory diseases,as well as the potential therapeutic applications of JMJD3 inhibitors.Additionally,we also discuss the challenges and opportunities associated with investigating the functions of JMJD3 and developing targeted inhibitors and propose feasible solutions to provide valuable insights into the functional exploration and discovery of potential drugs targeting JMJD3 for inflammatory diseases.
