Objective:To investigate the effects and mechanisms of zinc ion-loaded composite hydrogel (hereinafter referred to as the zinc-containing hydrogel) on infected full-thickness skin defect wounds in diabetic mice.Methods:This study was an experimental study. A poly (glycerol sebacate)-co-poly(ethylene glycol)-g-catechol prepolymer/quaternized-chitosan hydrogel (hereinafter referred to as the simple hydrogel) and a solid-state zinc-containing hydrogel with porous and good adhesion by adding zinc ions to the simple hydrogel were prepared. The release rate of zinc ions from the zinc-containing hydrogel after immersion in phosphate buffer solution (PBS) for 14 days was calculated. The concentration of methicillin-resistant Staphylococcus aureus (MRSA) cultured for 2 hours with the simple hydrogel, zinc-containing hydrogel, and PBS was measured. The scavenging ability of the simple hydrogel, zinc-containing hydrogel, and PBS for 1,1-diphenyl-2-picrylhydrazyl radical 2,2-diphenyl-1-(2, 4, 6-trinitrophenyl) hydrazyl (DPPH) was detected using microplate reader to reflect the ability of oxygen free radical removal. The length of vessels formed by human umbilical vein endothelial cells (HUVECs) cultured for 24 hours with the simple hydrogel, zinc-containing hydrogel, and PBS was measured. The cell viability of L929 cells cultured for 24 hours with the simple hydrogel, zinc-containing hydrogel, and PBS was detected using the cell counting kit-8. The mouse red blood cell suspension was divided into blank control group treated with PBS, simple hydrogel group, zinc-containing hydrogel group, and Triton X-100 group treated with corresponding solution. Hemolysis was detected using microplate reader after 2 hours of treatment, and the hemolysis rate was calculated. All experiments had a sample size of 3. Twenty-one C57BL/6J mice aged 6-8 weeks were taken, and a full-thickness skin defect wound was prepared in the symmetrical position on the back spine and infected with MRSA. Mice were divided into blank control group treated with PBS, simple hydrogel group, and zinc-containing hydrogel group treated with the corresponding hydrogel. Three days after injury, bacterial concentration in the wounds were measured in all groups of mice ( n=4). On day 0 (immediately), 3, 7, and 14 after injury, the wound infection status of mice was generally observed and the wound healing rate was calculated ( n=5). Hematoxylin-eosin staining and Masson staining were used to detect new epithelium and collagen formation in the wounds of mice on day 14 after injury. Immunofluorescence staining was used to detect neovascularization and distribution of M2 macrophages in the wounds of mice. Results:After immersion for 14 days, the release rate of zinc ions of the zinc-containing hydrogel was (70.5±4.6)%. Compared with the zinc-containing hydrogel, the bacterial concentration was significantly increased after 2 hours of culture with PBS and the simple hydrogel ( P<0.05). The DPPH scavenging rate of the zinc-containing hydrogel was significantly higher than that of PBS and the simple hydrogel (with P values all <0.05). The length of vessels formed by HUVECs cultured for 24 hours with the zinc-containing hydrogel was significantly longer than that cultured with PBS ( P<0.05). Compared with PBS and the simple hydrogel, the cell viability of L929 cells cultured for 24 hours with the zinc-containing hydrogel was significantly higher ( P<0.05). After 2 hours of incubation, compared with that in Triton X-100 group, the hemolysis rate of red blood cells in blank control, simple hydrogel, and zinc-containing hydrogel groups was significantly reduced ( P<0.05); and the hemolysis rate of red blood cells in the latter three groups was similar ( P>0.05). On day 3 after injury, the bacterial concentration in the wounds of mice in zinc-containing hydrogel group was significantly lower than that in blank control and simple hydrogel groups (with P values all <0.05). From day 3 to day 14 after injury, the wounds of mice in all the three groups were gradually healing, and on day 14 after injury, the wounds of mice in the zinc-containing hydrogel group were basically healed. On day 7 after injury, the wound healing rate of mice in zinc-containing hydrogel group was (72.4±8.4)%, which was significantly higher than that of blank control and simple hydrogel groups, being (31.6±6.7)% and (44.7±5.4)%, respectively(with P values all< 0.05). On day 14 after injury, the wound healing rate of mice in zinc-containing hydrogel group was (92.7±4.3)%, which was significantly higher than (73.5±7.4)% in blank control group ( P<0.05). On day 14 after injury, compared with that in blank control and simple hydrogel groups, the newly formed epidermis in mice wound of zinc-containing hydrogel group was longer and thicker, with more collagen deposition, and a more abundant distribution of new vessels and M2 macrophages. Conclusions:The zinc-containing hydrogel exhibits good biocompatibility, oxygen free radical scavenging capacity, and antimicrobial effects both in vitro and in vivo, as well as angiogenic promotion capability. It can provide sustained release of zinc ions to promote re-epithelialization and collagen synthesis, thus enhancing the healing of infected full-thickness skin defect wounds in diabetic mice.

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 investigate the effect of phorbol-12-myristate-13-ace-tate (TPA) on the proliferation and apoptosis of acute promyelocytic leukemia cell line NB4 and its molecular mechanism. METHODS: The effect of different concentrations of TPA on the proliferation of NB4 cells at different time points was detected by CCK-8 assay. The morphological changes of NB4 cells were observed by Wright-Giemsa staining. The cell cycle and apoptosis of NB4 cells after TPA treatment were detected by flow cytometry. The mRNA expressions of NB4 cells after TPA treatment were analyzed by high-throughput microarray analysis and real-time quantitative PCR. Western blot was used to detect the protein expression of CDKN1A, CDKN1B, CCND1, MYC, Bax, Bcl-2, c-Caspase 3, c-Caspase 9, PIK3R6, AKT and p-AKT. RESULTS: Compared with the control group, TPA could inhibit the proliferation of NB4 cells, induce the cells to become mature granulocyte-monocyte differentiation, and also induce cell G₁ phase arrest and apoptosis. Differentially expressed mRNAs were significantly enriched in PI3K/AKT pathway. TPA treatment could increase the mRNA levels of CCND1, CCNA1, and CDKN1A, while decrease the mRNA level of MYC. It could also up-regulate the protein levels of CDKN1A, CDKN1B, CCND1, Bax, c-Caspase 3, c-Caspase 9, and PIK3R6, while down-regulate MYC, Bcl-2, and p-AKT in NB4 cells. CONCLUSION TPA induces NB4 cell cycle arrest in G₁ phase and promotes its apoptosis by regulating PIK3/AKT signaling pathway.

Objective: To investigate the incidence and trend of short-term outcomes among preterm infants born <34 weeks' gestation. Methods: A secondary analysis of data from the standardized database established by a multicenter cluster-randomized controlled study "reduction of infection in neonatal intensive care units (NICU) using the evidence-based practice for improving quality (REIN-EPIQ) study". This study was conducted in 25 tertiary NICU. A total of 27 192 infants with gestational age <34 weeks at birth and admitted to NICU within the first 7 days of life from May 2015 to April 2018 were enrolled. Infants with severe congenital malformation were excluded. Descriptive analyses were used to describe the mortality and major morbidities of preterm infants by gestational age groups and different admission year groups. Cochran-Armitage test and Jonckheere-Terpstra test were used to analyze the trend of incidences of mortality and morbidities in 3 study-years. Multiple Logistic regression model was constructed to analyze the differences of outcomes in 3 study-years adjusting for confounders. Results: A total of 27 192 preterm infants were enrolled with gestational age of (31.3±2.0) weeks at birth and weight of (1 617±415) g at birth. Overall, 9.5% (2 594/27 192) of infants were discharged against medical advice, and the overall mortality rate was 10.7% (2 907/27 192). Mortality for infants who received complete care was 4.7% (1 147/24 598), and mortality or any major morbidity was 26.2% (6 452/24 598). The incidences of moderate to severe bronchopulmonary dysplasia, sepsis, severe intraventricular hemorrhage or periventricular leukomalacia, proven necrotizing enterocolitis, and severe retinopathy of prematurity were 16.0% (4 342/27 192), 11.9% (3 225/27 192), 6.8% (1 641/24 206), 3.6% (939/25 762) and 1.5% (214/13 868), respectively. There was a decreasing of the overall mortality (P<0.001) during the 3 years. Also, the incidences for sepsis and severe retinopathy of prematurity both decreased (both P<0.001). However, there were no significant differences in the major morbidity in preterm infants who received complete care during the 3-year study period (P=0.230). After adjusting for confounders, infants admitted during the third study year showed significantly lower risk of overall mortality (adjust OR=0.62, 95%CI 0.55-0.69, P<0.001), mortality or major morbidity, moderate to severe bronchopulmonary dysplasia, sepsis and severe retinopathy of prematurity, compared to those admitted in the first study year (all P<0.05). Conclusions: From 2015 to 2018, the mortality and major morbidities among preterm infants in Chinese NICU decreased, but there is still space for further efforts. Further targeted quality improvement is needed to improve the overall outcome of preterm infants.

Objective: To analyze the clinical characteristics of children with Burkitt lymphoma (BL) and to summarize the mid-term efficacy of China Net Childhood Lymphoma-mature B-cell lymphoma 2017 (CNCL-B-NHL-2017) regimen. Methods: Clinical features of 436 BL patients who were ≤18 years old and treated with the CNCL-B-NHL-2017 regimen from May 2017 to April 2021 were analyzed retrospectively. Clinical characteristics of patients at disease onset were analyzed and the therapeutic effects of patients with different clinical stages and risk groups were compared. Survival analysis was performed by Kaplan-Meier method, and Cox regression was used to identify the prognostic factors. Results: Among 436 patients, there were 368 (84.4%) males and 68 (15.6%) females, the age of disease onset was 6.0 (4.0, 9.0) years old. According to the St. Jude staging system, there were 4 patients (0.9%) with stage Ⅰ, 30 patients (6.9%) with stage Ⅱ, 217 patients (49.8%) with stage Ⅲ, and 185 patients (42.4%) with stage Ⅳ. All patients were stratified into following risk groups: group A (n=1, 0.2%), group B1 (n=46, 10.6%), group B2 (n=19, 4.4%), group C1 (n=285, 65.4%), group C2 (n=85, 19.5%). Sixty-three patients (14.4%) were treated with chemotherapy only and 373 patients (85.6%) were treated with chemotherapy combined with rituximab. Twenty-one patients (4.8%) suffered from progressive disease, 3 patients (0.7%) relapsed, and 13 patients (3.0%) died of treatment-related complications. The follow-up time of all patients was 24.0 (13.0, 35.0) months, the 2-year event free survival (EFS) rate of all patients was (90.9±1.4) %. The 2-year EFS rates of group A, B1, B2, C1 and C2 were 100.0%, 100.0%, (94.7±5.1) %, (90.7±1.7) % and (85.9±4.0) %, respectively. The 2-year EFS rates was higher in group A, B1, and B2 than those in group C1 (χ²=4.16, P=0.041) and group C2 (χ²=7.21, P=0.007). The 2-year EFS rates of the patients treated with chemotherapy alone and those treated with chemotherapy combined with rituximab were (79.3±5.1)% and (92.9±1.4)% (χ²=14.23, P<0.001) respectively. Multivariate analysis showed that stage Ⅳ (including leukemia stage), serum lactate dehydrogenase (LDH)>4-fold normal value, and with residual tumor in the mid-term evaluation were risk factors for poor prognosis (HR=1.38,1.23,8.52,95%CI 1.05-1.82,1.05-1.43,3.96-18.30). Conclusions: The CNCL-B-NHL-2017 regimen show significant effect in the treatment of pediatric BL. The combination of rituximab improve the efficacy further.

Objective:To explore the effect and mechanism of Xiangshenwan on ulcerative colitis （UC） induced by dextran sulfate sodium （DSS） in mice based on the classic Toll-like receptor （TLR）/nuclear factor kappa B （NF-κB） signaling pathway. Method:The experimental mice were divided into a normal group， a model group， a Xiangshenwan group， and a mesalazine group. The mice， except for those in the normal group， received 3% DSS solution for 7 days to establish the acute UC model and were treated with Xiangshenwan （5 g·kg^-1） and mesalazine （300 mg·kg^-1） continuously from the 1st day to the 10th day of modeling. The body weight， disease activity index （DAI）， colon weight， intestinal weight index， colon length， colon weight per unit length， and pathological changes of mice were evaluated respectively. The protein expression of TLR5， myeloid differentiation factor 88 （MyD88）， interleukin-1 receptor-associated kinase 4 （IRAK4）， tumor necrosis factor receptor-associated factor 6 （TRAF6）， transforming growth factor β-activated kinase 1 （TAK1）， p38 mitogen-activated protein kinase （MAPK）， NF-κB， IRAK1， TAK1-binding protein 1 （TAB1）， TAB2， mitogen-activated protein kinase kinase 3 （MKK3）， MKK6 and cyclic adenosine monophosphate response element-binding protein （CREB） in colon tissues of mice was detected by Western blot. Result:Compared with the normal group， the model group showed decreased body weight of mice， increased DAI scores， elevated colon weight， intestinal weight index， and colon weight per unit length， shortened colon length， severe colonic mucosal injury， and up-regulated protein expression of TLR5， MyD88， IRAK4， TRAF6， TAK1， p38 MAPK， NF-κB， IRAK1， TAB1， TAB2， MKK3， MKK6， and CREB in colon tissues （P<0.05， P<0.01）. Compared with the model group， the Xiangshenwan group and the mesalazine group displayed increased body weight of mice， decreased DAI scores， declining colon weight， intestinal weight index， and colon weight per unit length， increased colon length， improved colonic mucosal injury， and down-regulated protein expression of TLR5， MyD88， IRAK4， TRAF6， TAK1， p38 MAPK， NF-κB， IRAK1， TAB1， TAB2， MKK3， MKK6， and CREB in colon tissues （P<0.05， P<0.01）. Conclusion:Xiangshenwan can effectively treat DSS-induced UC presumedly by the inhibition of TLR/NF-κB signaling pathway.

Objective:To explore the effect of task-based rehabilitative training on neural circuit plasticity and forelimb motor function after C₅ spinal cord injury in mice. Methods:A total of 21 healthy C57/BL mice were randomly and equally divided into sham group, model group and training group. The model was established by left C₅ spinal cord crush injury. The lamina was removed without damaging the spinal cord in the sham group. Four weeks after injury, the training group received task-based rehabilitative training for four weeks. The horizontal ladder and rearing tests were used to assess motor function for forelimb before injury, and three days, two weeks, four weeks, six weeks and eight weeks after injury. The axons of the corticospinal tract in all mice were observed six weeks after injury by using biotinylated dextran amin (BDA) anterograde tracing. Eight weeks after injury, motor-evoked potential was applied to measure nerve conduction velocities in forelimb, while the axon sprouting and syntagmatic relation of neuron in the anterior horn of gray matter above lesion were observed by immunofluorescence double-labeling of BDA/neuron-specific nuclei protein (NeuN); the expression of Synapsin in the anterior horn of gray matter at lesion was observed by immunofluorescence double-labeling of NeuN/Synapsin I. Results:Eight weeks after injury, the latency of P1 and N1 was longer in the model group than in the sham group (P < 0.05), and was shorter in the training group than in the model group (P < 0.05). Compared with the sham group, the error rate of left forelimb increased, and the usage rate decreased (P < 0.05) in the model group and the training group; compared with the model group, the error rate of left forelimb decreased six weeks and eight weeks after injury (P < 0.05), and the usage rate increased eight weeks after injury (P < 0.05) in the treatment group. Compared with the model group, more axon sprouting co-localized with neurons in the anterior horn of gray matter above lesion (P < 0.05), and the expression of Synapsin I increased in the training group (P < 0.05). Conclusion:Task-based rehabilitative training could promote the neural circuit plasticity and improve the motor function of forelimb after spinal cord injury in mice.

BACKGROUND: Oral inflammatory diseases usually cause alveolar bone loss and odontoseisis, and further impact dental occlusion. Extracorporeal shock wave therapy (ESWT) is a promising method for the repair of alveolar bone and improving osteogenic activity of alveolar osteoblasts, but its therapeutic efficacy and related mechanisms remain unclear. OBJECTIVE: To compare the effect of different intensities of ESWT on the proliferation and osteogenesis abilities of rat alveolar osteoblasts. METHODS: The rat alveolar osteoblasts were obtained and cultured in vitro, and further identified by alkaline phosphatase staining. 0.18, 0.36, and 0.50 mJ/mm2 ESWT was used to stimulate the rat alveolar osteoblasts, 100 pulses, respectively. RESULTS AND CONCLUSION: The levels of alkaline phosphatase and bone morphogenetic protein 2 were significantly increased in the 0.36 and 0.18 mJ/mm2 ESWT groups, especially in the 0.36 mJ/mm2 ESWT group (P < 0.05). 0.50 mJ/mm2 ESWT significantly decreased the proliferation ability of rat alveolar osteoblasts and downregulated the levels of alkaline phosphatase and bone morphogenetic protein 2 (P < 0.05). To conclude, ESWT (< 0.36 mJ/mm2) can improve the osteogenesis ability of rat alveolar osteoblasts with the intensity increasing, which provides a theoretical basis for the clinical use of ESWT in the alveolar bone repair.

BACKGROUNDPyroptosis is the term for caspase-1-dependent cell death associated with pro-inflammatory cytokines. The role of alveolar macrophage (AM) pyroptosis in the pathogenesis of the acute lung injury and acute respiratory distress syndrome (ALI/ARDS) remains unclear.

METHODSC57BL/6 wild-type mice were assigned to sham, lipopolysaccharide (LPS) + vehicle, LPS + acetyl-tyrosyl-valyl- alanyl-aspartyl-chloromethylketone (Ac-YVAD-CMK) and LPS + Z-Asp-Glu-Val-Asp-fluoromethylketone groups. Mice were given intraperitoneal (IP) injections of LPS. Drugs were IP injected 1 h before LPS administration. Mice were sacrificed 16 h after LPS administration, and AMs were isolated. Western blot analysis for active caspase-1 and cleaved caspase-3, evaluation of lung injury and a cytokine release analysis were performed. AMs were treated with LPS and adenosine triphosphate (ATP); caspase-1-dependent cell death was evaluated using flow cytometry; the apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) pyroptosomes were examined by immunofluorescence.

RESULTSThe expression of activated caspase-1 in AMs was enhanced following LPS challenge compared with the sham group. In the ex vivo study, the caspase-1/propidium iodide-positive cells, caspase-1 specks and ASC pyroptosomes were up-regulated in AMs following LPS/ATP stimulation. The specific caspase-1 inhibitor Ac-YVAD-CMK inhibited the activation of caspase-1 and pyroptotic cell death. Ac-YVAD-CMK also reduced the lung injury, pulmonary edema and total protein in bronchoalveolar lavage fluid (BALF). In addition, Ac-YVAD-CMK significantly inhibited interleukin-α2 (IL-1α2) release both in serum and BALF and reduced the levels of IL-18, tumor necrosis factor-α± (TNF-α±), High Mobility Group Box 1 (HMGB1) in BALF during LPS-induced ALI/ARDS.

CONCLUSIONSThis study reported AM pyroptosis during LPS-induced ALI/ARDS in mice and has demonstrated that Ac-YVAD-CMK can prevent AM-induced pyroptosis and lung injury. These preliminary findings may form the basis for further studies to evaluate this pathway as a target for prevention or reduction of ALI/ARDS.

OBJECTIVETo explore the association between dyslipidemia and different subtypes of hypertension among Zhejiang population.

METHODSFrom June to October in 2010, 19 113 local residents aged ≥ 18 years old were selected among 7571 families from fifteen counties in Zhejiang by four stage stratified-random sampling method. A self-designed questionnaire was adopted to collect information on demographic characteristics, physical activity and life style. At the same time, physical examinations including height, weight, blood pressure and blood lipids were carried out.

RESULTSA total of 19 113 participants completed the interviews, physical examinations and collected the blood samples.Excluding those who did not meet the criteria, 14 731 were finally enrolled in the study. The prevalence rates of isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), systolic and diastolic hypertension (SDH) were 7.16% (1055/14 731, standardized rate:5.46%), 4.60% (677/14 731, standardized rate:4.41%), 7.09% (1045/14 731, standardized rate:5.75%), respectively. Among normal blood pressure group, subjects with normal TC, high TC and abnormal TC were separately 10 571 (88.43%), 1173 (9.81%) and 210 (1.76%); subjects with normal HDL-C and low HDL-C were separately 6885 (57.60%) and 5069 (42.40%); subjects with normal TG, high TG, abnormal TG were separately 9952 (79.91%), 1213 (10.15%) and 1189(9.95%).In ISH group, subjects with normal TC, high TC and abnormal TC were separately 826 (78.29%), 188 (17.82%) and 41 (3.89%); subjects with normal HDL-C and low HDL-C were separately 666(63.13%) and 389 (36.87%); subjects with normal TG, high TG and abnormal TG were separately 737 (69.86%), 150 (14.22%) and 168 (15.92%). Multi factor analysis showed that high TG and abnormal TG were associated with ISH (OR (95%CI):1.43 (1.16-1.76), 1.65 (1.34-2.03) respectively). Among IDH group, subjects with normal TC, high TC, abnormal TC were separately 556(82.13%), 99(14.62%) and 22 (3.25%); subjects with normal HDL-C, low HDL-C were separately 335 (49.48%) and 342 (50.52%); subjects with normal TG, high TG, and abnormal TG separately were 402 (59.38%), 107 (15.81%) and 168 (24.82%). The multi factor analysis showed that high TG and abnormal TG could increase the risk of IDH (OR(95%CI):1.57 (1.24-1.98), 2.18 (1.76-2.70) respectively). Among SDH group, subjects with normal TC, high TC and abnormal TC were 817 (78.18%), 193 (18.47%) and 35 (3.35%); subjects with normal HDL-C and abnormal HDL-C were separately 599 (57.32%) and 446 (42.68%); subjects with normal TG, high TG, abnormal TG were separately 675 (64.59%), 164 (15.69%) and 206 (19.71%). The multi factor analysis showed that high TC, high TG and abnormal TG were also associated with the increased risk of SDH (OR (95%CI):1.38 (1.14-1.67), 1.43(1.18-1.75), 1.73 (1.43-2.10) respectively).

CONCLUSIONDyslipidemia is an important factor of different subtypes of hypertension among Zhejiang population, especially triglycerides. Dyslipidemia screening should be strengthened to reduce the risk of cardiovascular diseases.
