Objective To explore the associations of parental smoking and alcohol consumption during the periconceptional period and their interactions with risk of congenital heart disease(CHD)in offspring.Methods The parents of children with simple CHD aged 0 to 1 year(n=683)were recruited as the case group,while the parents of healthy children aged 0 to 1 year(n=740)served as the control group.A case-control study was conducted,and a questionnaire was used to collect information on perinatal exposures.After controlling for relevant confounding factors using multivariate logistic regression analysis and propensity score matching,the associations of parental smoking and alcohol consumption during the periconceptional period and their interactions with CHD were examined,as well as the cumulative effects of smoking and drinking on CHD risk.Results Maternal active smoking(OR=2.91,95%CI:1.60-5.30),passive smoking(OR=1.94,95%CI:1.56-2.42),and alcohol consumption(OR=2.59,95%CI:1.89-3.54),as well as paternal smoking(OR=1.52;95%CI:1.22-1.90)and drinking(OR=1.48,95%CI:1.19-1.84),were associated with an increased risk of CHD in offspring.There was no interaction between parental smoking and drinking behaviors during the periconceptional period concerning the risk of CHD in offspring(P>0.05).The more parents'smoking and drinking behaviors during the perinatal pregnancy,the higher the risk of CHD in their offspring(OR=1.50,95%CI:1.36-1.65).Conclusions Parental smoking and alcohol consumption during the periconceptional period are associated with the occurrence of CHD in offspring,and there is a cumulative effect on CHD risk,suggesting that reducing tobacco and alcohol exposure during the periconceptional period may lower the incidence of CHD.

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.

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 morphological typing and clinical significance of the distal tibiofibular syndesmosis fibular notch based on CT images. Methods According to the inclusion and exclusion ceiteria‚ the imaging data of patients undergoing ankle joint CT examination were analyzed‚ and the inferior tibiofibular joint fibula notch was classified according to the morphological characteristics. The measurements included 8 distances. There were 123 males and 102 females‚ all of whom were Han nationality‚ aged 18-60 years old. Results Retrospectively analyzed the result of 225 patients from December 2013 to December 2022. The distal tibiofibular syndesmosis fibular notch was divided into four types according to morphological characteristics‚ C-shaped (50. 67%)‚ V-shaped (26. 67%)‚ flat-shaped (15. 11%) and L-shaped (7. 56%). The angle between the anterior and posterior facets of the flat shape (145. 56 ± 9. 25)° was the largest and the angle between the anterior and posterior facets of the L shape (125. 07 ± 13. 54)° was the smallest(P< 0. 05); the depth of the notch in the flat shape (3. 11 ± 0. 83) mm was the smallest and in the L shape (4. 47±1. 11) mm was the largest(P<0. 05);The posterior facet length (13. 06 ± 3. 56) mm and anterior tibiofibular gap (3. 83±1. 49) mm on left were larger than on the right side (P<0. 05); The posterior facet length (13. 36 ± 3. 46) mm‚ fibular notch depth (3. 93 ± 1. 10) mm and vertical distance of tibiofibular overlap (9. 10 ± 2. 55) mm larger in men than in women (P<0. 05). Conclusion In this study‚ the data related to the inferior tibiofibular syndesmosis notch were measured and divided into four types according to the shape. The flat inferior tibiofibular syndesmosis notch is more likely to have chronic ankle instability‚ and the fibula is more likely to move forward during anatomical reduction. The inferior tibiofibular syndesmosis of L-shaped and C-shaped notches is more prone to posterior displacement of fibula or poor rotation reduction during anatomical reduction.

Objective:This multi-centre study was conducted to assess the efficacy of various preoperative/pre-transfusion screening methods for blood transmitted disease.Methods:From July 2021 to December 2021, plasma samples of patients admitted to 10 hospitals were collected for screening preoperative/pre-transfusion blood transmitted disease. Nucleic acid detection technology was used to detect hepatitis B virus (HBV) DNA, hepatitis C virus (HCV) RNA and human immunodeficiency virus (HIV)(1+2) RNA, and the results were compared with the immuno-serological methods. χ 2 test and Kappa test were used to analyze the efficacy of these two methods. Results:A total of 8 655 valid specimens were collected from 10 hospitals. There was a statistically significant difference in the positive detection rate of HCV between the two methods ( P<0.001). There was no significant difference in the positive detection rate of HBV and HIV assessed by the two methods ( P>0.05), but the number of positive cases detected by HBV DNA and HIV RNA (218 and 4 cases) was significantly higher than the corresponding serological results (216 and 2 cases). At the same time, there were HBV, HCV and HIV immuno-serological omissions by the immuno-serological methods, among which 28 cases were HBsAg negative and HBV DNA positive, 2 cases were HCV antibody negative and HCV RNA positive, and 2 cases were HIV antigen/antibody negative and HIV RNA positive. In addition, in the 66 samples with inconsistent results from the two detection methods, 83.3% (55/66), 68.2% (45/66), 63.6% (42/66) and 62.1% (41/66) of patients aged was>45 years, tumor, surgery and male, respectively. Conclusions:Compared with immuno-serological tests, nucleic acid tests have the advantage in terms of sensitivity on detecting HBV, HCV and HIV infection and could reduce missed detection. The risk of transmission can be reduced by adding HBV, HCV, and HIV nucleic acid tests to preoperative/pre-transfusion immuno-serological tests screening for patients over 45 years of age and tumor patients.

OBJECTIVE: To investigate the effect and mechanism of acupoint injection with 0.1% vitamin C+vitamin B complex solution (V_C+V_BCo) at "Tiantu" (CV 22), "Quchi" (LI 11) and "Zusanli" (ST 36) in mouse model of pneumonia induced by influenza A virus (A/PR/8/34 [H1N1], PR8). METHODS: Sixty male ICR mice were randomized into 6 groups, i.e. control group, model group, acupoint injection group, intraperitoneal injection group, non-target point group and ribavirin group, 10 mice in each one. Except the control group, the pneumonia models were induced by slow nasal dripping PR8 virus in the other groups. On the 2nd day of experiment, V_C+V_BCo solution, 40 μL was injected at "Tiantu" (CV 22), "Quchi" (LI 11, left) and "Zusanli" (ST 36, left) in the acupoint injection group; V_C+V_BCo solution, 120 μL was injected intraperitoneally in the intraperitoneal injection group; V_C+V_BCo solution, 40 μL was injected at non-target acupoints (0.5 cm away from "Tiantu" [CV 22] to the left side, "Quchi" [LI 11, left] and "Zusanli" [ST 36, left]) in the non-target point group; and ribavirin solution, 120 μL was injected intraperitoneally in the ribavirin group. The intervention was delivered once daily, for consecutive 7 days. Three parallel experiments were undertaken. The mean death rate and survival time were assessed in each group, the body mass and lung index were compared among groups. Using HE staining, the morphology of lung tissue was observed; and with real-time fluorescence quantitative PCR, viral load in lung tissue was detected. The concentrations of inflammatory factors (tumor necrosis factor α [TNF-α], interleukin [IL]-1β, IL-10) were detected in lung tissue of each group using ELISA; and those of oxidative stress markers (superoxide dismutase [SOD], glutathione peroxidase [GSH-Px], malondialdehyde [MDA]) were detected with chemiluminescence method. RESULTS: Compared with the control group, the body mass was decreased and lung index was increased in the model group (P<0.01). In comparison with the model group, body mass was increased in the acupoint injection group (P<0.05), lung index was reduced in the acupoint injection group the and ribavirin group (P<0.05); the mean death rate was decreased and the mean survival time prolonged in the mice of the acupoint injection group (P<0.01, P<0.05); and the mean death rate was reduced in the mice of the ribavirin group (P<0.05). In the model group, the alveolar structure was not integral, the alveolar septum was thickened, inflammatory cells were infiltrated and red blood cells exudated seriously (P<0.01). Compared with the model group, in the acupoint injection group and the ribavirin group, the alveolar structure was integral, the thickened alveolar septum was alleviated; and the infiltration of inflammatory cells and the exudation of red blood cells were reduced remarkably. The viral load was reduced in the mice of the ribavirin group when compared with the model group (P<0.01). Compared with the control group, the concentrations of TNF-α, IL-1β and MDA in lung tissue were increased and those of IL-10, SOD and GSH-Px were reduced in the model group (P<0.01). In the acupoint injection group and the ribavirin group, the concentrations of TNF-α, IL-1β and MDA were reduced in lung tissue and those of IL-10, SOD and GSH-Px were increased (P<0.05, P<0.01) when compared with the model group. CONCLUSION Acupoint injection with V_C+V_BCo solution may alleviate inflammatory responses and oxidative stress in lung tissue of the PR8-induced pneumonia mice, improve survival rate and prolong the survival time in the case of no effect of the viral load.

Methods hDPSCs were obtained from the pulp tissues of premolar, and the characteristic surface antigens were identified by flow cytometry. Cell Counting Kit-8 (CCK-8) assay was used to test the cytotoxicity of quercetin. Alkaline phosphatase (A L P) and alizarin red staining were used to detect the osteogenic ability of cells in vitro. The expression of osteogenic genes was detected by qPCR. Four round calvarial bone defects with a diameter of 8 mm were created in 10 male New Zealand rabbits, and they were differentiated and randomized into four groups. Group A, hDPSCs cultured on Bio-Oss

OBJECTIVE: To observe the eliminating effects of moxibustion at "Baihui" (GV 20), "Fengfu" (GV 16) and "Dazhui" (GV 14) on amyloid β-peptide (Aβ) in brain of the amyloid precursor protein/presenili1 (APP/PS1) double-transgenic mice with Alzheimer's disease (AD) by regulating the phosphoinositide 3-kinases/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway. METHODS: A total of 60 APP/PS1 double-transgenic mice with AD were randomly divided into a model group, a moxibustion group, a rapamycin group and a combination group (treated with moxibustion and inhibitor), 15 mice in each group, another 15 male C57BL/6J mice with same age and background were selected as the control group. In the moxibustion group, pressing moxibustion was applied at "Baihui" (GV 20) while the mild moxibustion was applied at "Fengfu" (GV 16) and "Dazhui" (GV 14). The treatment was manipulated for 20 min each time, once a day for 2 weeks. In the rapamycin group, rapamycin (2 mg/kg) was given by intraperitoneal injection once a day for 2 weeks. On the basis of the treatment in the moxibustion group, 3-methyladenine (1.5 mg/kg) was given by intraperitoneal injection once a day for 2 weeks. The mice in the control and the model group received normal diet and no intervention was given for 2 weeks. Immunohistochemica method was used to measure the levels of Aβ in the cerebral cortex and hippocampal, transmission electron microscopy was used to observe the formation of autophagosome in hippocampus, and Western blot method was used to observe the levels of PI3K, Akt, p-Akt, mTOR and p-mTOR in hippocampus. RESULTS: Compared with the control group, the levels of Aβ in the cerebral cortex and hippocampal were increased in the model group (<0.01). Compared with the model group, the levels of Aβ in the cerebral cortex and hippocampal were decreased in the moxibustion group, the rapamycin group and the combination group (all <0.01), compared with the moxibustion group, the levels of Aβ in the cerebral cortex and hippocampal were increased in the combination group (<0.01), while there was no significant difference between the moxibustion group and the rapamycin group in the levels of Aβ（>0.05）. Compared with the rapamycin group, the levels of Aβ in the cerebral cortex and hippocampal were increased in the combination group (<0.01). In the model group, the cytoplasmic utophagic vacuoles and organelles of neuron were reduced. In the moxibustion group, the utophagic vacuoles were increased, and the organelles showed deformation and atrophy. In the rapamycin group, the utophagic vacuoles were widely disturbed and few deformed organelles were found. In the combination group, few utophagic vacuoles were found and additional organelles showed deformation and atrophy. Compared with the control group, the levels of PI3K、Akt、p-Akt、mTOR and p-mTOR were increased in the model group (all <0.01). Compared with the model group, the levels of PI3K、Akt、p-Akt、mTOR and p-mTOR were reduced in the moxibustion group, the rapamycin group and the combination group (all <0.01). Compared with the moxibustion group, the levels of PI3K、Akt、and p-mTOR were increased in the rapamycin group and the levels of PI3K、Akt、p-Akt、mTOR and p-mTOR were increased in the combination group (all <0.01). Compared with the rapamycin group, the levels of PI3K、Akt、p-Akt、mTOR and p-mTOR were increased in the combination group (<0.01). CONCLUSION Moxibustion at acupoints of governor vessel can enhance the autophagy process on Aβ in brain of the APP/PS1 double-transgenic AD mice, which may be associated with its effects on inhibiting the abnormal activation of PI3K/Akt/mTOR signaling pathway.
