OBJECTIVE: To explore the early changes in various liver function indicators in critically injured trauma patients assessed by intelligent calculation method, aiming to develop more advantageous diagnostic and treatment strategies for traumatic liver injury. METHODS: A retrospective study was conducted. Critically injured trauma patients [injury severity score (ISS) ≥ 16, age > 18 years old] admitted to the Emergency Medical Center of Tianjin Fifth Central Hospital from January 1, 2022, to December 1, 2023 were enrolled. ISS score and acute physiology and chronic health evaluation II (APACHE II) assessed by intelligent calculation method were collected upon patient admission to the emergency medical center. Trends in liver function indicators in fasting venous serum were analyzed at 6, 24 and 72 hours after admission, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), γ-glutamyl transferase (GGT), lactate dehydrogenase (LDH), albumin (ALB), total bilirubin (TBil), prothrombin time (PT). Patients were grouped based on APACHE II scores into those with APACHE II < 15 and APACHE II ≤ 15, and liver function indicators within 6 hours of admission were compared between the two groups. RESULTS: A total of 112 critically injured trauma patients were included, with 83 males and 29 females, an average age of (47.78±14.84) years old. The median ISS score was 21.0 (18.0, 26.0). The most common cause of injury for critically injured trauma patients was road traffic accidents (68 cases, accounting for 60.71%), followed by falls from heights, compression injuries, heavy object injuries, knife stabs, and explosion injuries. The most common injured areas was the limbs and pelvis (97 cases, accounting for 86.61%), followed by chest injuries, surface skin and soft tissue injuries, abdominal and pelvic organ injuries, head injuries, and facial injuries. The proportion of elevated LDH, AST, and ALT within 6 hours of admission was 77.68%, 79.46%, and 52.68%, respectively, while the proportion of decreased ALB was 75.89%, the abnormal rates of ALP, GGT, TBil, and PT were all below 50%. The ALT and AST levels of patients at 24 hours and 72 hours after admission were significantly lower than those at 6 hours after admission [ALT (U/L): 37.0 (22.0, 66.0), 31.0 (21.2, 52.0) vs. 41.0 (25.0, 71.0), AST (U/L): 55.5 (30.0, 93.5), 40.0 (27.0, 63.2) vs. 69.5 (39.0, 130.8), all P < 0.05]. There was no statistically significant difference in ISS score between APACHE II > 15 group (45 cases) and APACHE II ≤ 15 group [67 cases; 21.0 (18.5, 26.5) vs. 20.0 (17.0, 22.0), P > 0.05]. Nevertheless, compared with patients with APACHE II ≤ 15, patients with APACHE II > 15 have a higher abnormality rate of ALT and AST within 6 hours of admission [ALT abnormal rate: 66.44% (29/45) vs. 44.78% (30/67), AST abnormal rate: 93.33% (42/45) vs. 70.15% (47/67), both P < 0.05], and the levels of ALT and AST were higher [ALT (U/L): 56.0 (30.0, 121.0) vs. 35.0 (21.0, 69.0), AST (U/L): 87.0 (48.0, 233.0) vs. 52.0 (31.0, 117.0), both P < 0.05]. CONCLUSIONS Severe trauma patients frequently exhibit a high incidence of reversible early liver function impairment. Based on intelligent calculation method, the utilization of both the ISS and APACHE II scores demonstrates a distinct advantage in the assessment of their early liver injury.

Objective: To explore the relationship between dietary behavior, dietary frequency and central precocious puberty (CPP) among children in Wuhan, so as to provide a scientific basis for elucidating the possible and related dietary factors leading to precocious puberty. Methods: From February to December 2023, 100 children with CPP and 100 healthy children were collected in Wuhan Children s Hospital for a case control study. Questionnaires and interviews were used to collect demographic information, child lifestyle, as well as dietary behavior and dietary frequency in the past six months. Conditional Logistic regression model was used to analyze the relationship of children s dietary behavior and dietary frequency with CPP. Results: No associations were found between three dietary behavior, including emotional eating, restrictive eating, and external eating, with CPP at baseline ( P >0.05). In the association analysis of dietary frequency and CPP, the risk of CPP was higher in those who consumed red meat >5 times/week ( OR =1.93, 95% CI =1.01-3.68), carbonated beverages ≥4 times/month ( OR =2.70, 95% CI =1.03-7.08), fruit juices ≥4 times/month ( OR =2.31, 95% CI =1.02-5.25), and nutritional supplementation ( OR =2.77, 95% CI =1.47- 5.22 ), whereas the risk of CPP was lower in those who consumed nuts ≥4 times/month ( OR =0.21, 95% CI =0.08-0.57) ( P < 0.05 ). Conclusion Consumption of higher amounts of red meat, high frequency of carbonated and juice based sugary drinks, and nutrient supplementation may be contributing factors to the development of CPP, whereas regular consumption of nuts is less likely to be associated with the development of CPP.

Objective:To analyze the reinfection rates in people previously infected with SARS-CoV-2 in Zhengzhou and Yuzhou cities (first infected with Delta/B.1.617.2 variant), and Anyang city (first infected with Omicron/BA.1.1 variant) in January 2022 and the population characteristics, and compare the differences in antibody levels among different populations.Methods:Serum samples were collected from 371 previously infected, 134 reinfected and 19 uninfected people for IgG antibody detection. Among them, serum samples from 45 previously infected, 44 reinfected and 19 uninfected people were tested with different novel coronavirus variants (early original strain, BA.5.2 variant, XBB.1.5 variant) for neutralizing antibody detection.Results:The rate of reinfection was 32.82% (85/259) in Zhengzhou and Yuzhou cities, and 19.92% (49/246) in Anyang city. The IgG antibody level in reinfected people was higher than that in previously infected and uninfected people ( P<0.05). The IgG antibody level in uninfected group was higher in people vaccinated within three months than in those vaccinated six months ago ( P<0.05). The IgG antibody level in the group receiving four doses of vaccine was higher than that in the group receiving three doses of vaccine ( P<0.05). The results of true virus neutralization antibody detection showed that in the Zhengzhou and Yuzhou cases, the level of neutralization antibody against the early original strain was higher than those against the BA.5.2 variant and the XBB.1.5 variant ( P<0.05), and the level of neutralizing antibody against BA.5.2 variant was higher than that against XBB.1.5 variant ( P<0.05). In Anyang city cases, the level of neutralizing antibody against the early original strain was higher than those against BA.5.2 variant and XBB.1.5 variant ( P<0.05); in the reinfected population, the level of neutralizing antibody against the early original strain was higher than that against the XBB.1.5 variant ( P<0.05). In addition, the levels of all neutralizing antibodies in both previously infected and reinfected people were higher than those in uninfected people ( P<0.05). The level of neutralizing antibody in the infected population in Zhengzhou and Yuzhou cities was higher than that in the infected population in Anyang city and in uninfected population ( P<0.05). The levels of antibodies against BA.5.2 and anti-XBB.1.5 variants in infected people in Zhengzhou and Yuzhou cities were higher than those in uninfected people ( P<0.05). The level of neutralizing antibody against BA.5.2 variants in the previously infected population in Anyang city was higher than that in the uninfected population ( P<0.05), and the level of neutralizing antibody against XBB.1.5 variants in the infected population in Anyang city was higher than that in the uninfected population ( P<0.05). Conclusions:After infection with SARS-CoV-2, the neutralizing antibodies produced in the human body have a certain cross-protection effect on other variants, but the antibody level will gradually decrease over time. Protection from a previous early SARS-CoV-2 variants infection against the current main circulating Omicron variants (such as XBB variants) is low, and the immunity conferred by pervious infection or booster vaccination may not be able to provide sufficient protection against new variants.

OBJECTIVE To provide reference for clarifying improvement effects of Anemarrhena asphodeloides on sepsis- induced myocardial injury and potential material basis. METHODS Water extract of A. asphodeloides was extracted by thermal reflux method. Total xanthone and total saponins in A. asphodeloides were separated by macroporous adsorption resin. The mice model of sepsis-induced myocardial injury was established by intraperitoneal injection of lipopolysaccharide. The effects of the location of three extraction fractions and the monomers of A. asphodeloides as mangiferin， timosaponin AⅢ and timosaponin BⅡ on the survival rate of the model mice were explored. HE staining was used to observe the effects of mangiferin， timosaponin AⅢ and timosaponin BⅡ on myocardial morphology in model mice. The effects of mangiferin on mRNA expressions of inflammatory cytokines [interleukin-6 （IL-6）， IL-1β and tumor necrosis factor-α （TNF-α）] and the level of reactive oxygen species （ROS） in myocardial tissue of model mice were detected. RESULTS Compared with the model group， the survival rate of mice in the intervention group of total xanthone， total saponins and water extract was increased to different extents， especially total xanthone fraction. Mangiferin， timosaponin AⅢ and timosaponin BⅡcould improve the degree of myocardial cell swelling and muscle bundle arrangement disorder in model mice， especially mangiferin. Compared with model group， mRNA expressions of IL-6， IL- 1β and TNF- α， ROS level in myocardium of mice after mangiferin intervention were decreased to different extents. CONCLUSIONS The different extraction fractions of A. asphodeloides can improve survival rate of mice with sepsis-induced myocardial injury， especially total xanthone fraction. Mangiferin is the best among the three monomers of A. asphodeloides to improve sepsis-induced myocardial injury， which may play a role in anti-sepsis myocardial injury by anti-inflammation and antioxidantion.

Objective:To compare the efficacy of transcatheter arterial embolization (TAE) with laparotomy in the treatment of severe liver injury.Methods:A retrospective cohort study was conducted to analyze the clinical data of 48 patients with severe liver injury admitted to 909th Hospital of Joint Logistics Support Force (Affiliated Dongnan Hospital of Xianmen University Medical College) from December 2013 to June 2020, including 28 males and 20 females; aged 16-75 years [(45.7±6.2)years]. There were 25 patients with grade III, 15 grade IV and 8 grade V according to the American Association for the Surgery of Trauma (AAST) classification. After general treatments such as infusion and hemostasis, TAE was performed in 26 patients (TAE group) and laparotomy in 22 patients (laparotomy group). The operation time and length of hospital stay were compared between the two groups. Erythrocyte, hemoglobin and serum creatinine were compared before operation and at postoperative 1 day. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were analyzed before operation and at postoperative 1, 3, 7 days. Complications were observed.Results:All patients were followed up for 12-60 months [(17.1±9.1)months]. The operation time and length of hospital stay were (65.7±9.2)minutes and (21.6±6.6)days in TAE group, significantly shorter than (162.5±28.1)minutes and (31.5±7.4)days in laparotomy group ( P<0.05 or 0.01). There was no significant difference between the two groups referring to erythrocyte, hemoglobin and serum creatinine before operation and at postoperative 1 day (all P>0.05). There was no significant difference in ALT and AST between the two groups before operation (all P>0.05). TAE group showed ALT level of 1 154(884, 1 698)U/L, (975.3±400.9)U/L and (403.4±232.9)U/L at postoperative 1, 3, 7 days, significantly lower than 2 053(1 965, 2 132)U/L, (1 604.1±188.2)U/L and (915.3±160.5)U/L in laparotomy group (all P<0.05). TAE group showed AST level of (1 313.2±542.0)U/L, 525(302, 971)U/L and 174(84, 324)U/L at postoperative 1, 3, 7 days, significantly lower than (1 962.9±245.4)U/L, 1 478(1 089, 1 677)U/L and 837(674, 1 006)U/L in laparotomy group ( P<0.05 or 0.01). The complication rate was 26.9% (7/26) in TAE group, significantly lower than 59.1% (13/22) in laparotomy group ( P<0.05). Conclusion:For severe liver injury, TAE can significantly shorten operation time and length of hospital stay, accelerate the recovery of liver function and reduce the complication rate in comparison with laparotomy.

Objective : To explore the epicardial adipose tissue ( EAT) of patients with coronary heart disease , KLF7 stimulates macrophages to secrete inflammatory factors and promotes the differentiation and maturation of adipocytes through the NF⁃κB signaling pathway , and to clarify the mechanism of KLF7 in the occurrence and development of CAD. Methods : 30 patients with coronary heart disease ( CAD group) and 30 patients without coronary heart disease (non⁃CAD group) were collected , and general data and biochemical indicators were collected. qRT⁃PCR was used to detect the expression levels of KLF7 , APN , IL⁃6 , and TNF⁃α mRNA in EAT. Human THP⁃1 cells were cultured in vitro and induced into M1 type macrophages and 3T3 ⁃L1 preadipocytes. The cells were divied into 3 groups : KLF7 up⁃regulated group ( transfected with KLF7 mimic) , KLF7 down⁃regulated group ( transfected with siRNA knockdown KLF7 ) , NC group ( transfected oligopeptide sequence) , transfected two kinds of cells. qRT⁃PCR was used to detect the expression of APN , MCP⁃1 , IL⁃6 and TNF⁃α mRNA in M1 type macrophages , and the protein expression levels of key factors in the NF⁃κB signaling pathway were detected by Westren blot. The qRT⁃PCR method was used to detect APN , KLF4 , IL⁃6 , MCP⁃1 mRNA and adipocyte differentiation marker peroxisome proliferator⁃activated receptor⁃γ (PPARγ) in 3T3 ⁃L1 preadipocytes 24 h after transfection. CCAAT/enhancer binding protein α (C/EBPα ) , fatty acid binding protein 4 (FABP4) mRNA relative expression levels , and Westren blot was used to detect protein expression levels. Results : Compared with the non⁃CAD group , the expression of CAD group decreased , APN decreased , IL⁃6 and TNF⁃α increased significantly , and the difference was statistically significant (P < 0. 01) . KLF7 was highly expressed in human THP⁃1 derived M1 macrophages induced by inflammatory stimuli (LPS) . In M1 macrophages derived from human THP⁃1 , knocking down KLF7 could inhibit the release of inflammatory factors. Transfection with KLF7 ⁃siRNA could significantly inhibit LPS⁃induced phosphorylation of JNK⁃MAPKs , the level of p⁃p65 and the activation of p ⁃IκBa (P < 0. 05) . In 3T3 ⁃L1 preadipocytes , upregulation of KLF7 increased the expression of adipocyte differentiation markers PPARγ , C/EBPa , FABP4 mRNA , and promoted the differentiation of 3T3 ⁃L1 preadipocytes into adipocytes (P < 0. 05) . Conclusion The expression of KLF7 in EAT in CAD patients increases. KLF7 activates the activation of macrophages mediated by the JNK⁃NF⁃KB signaling pathway in EAT , promotes inflammation in EAT in CAD patients , and promotes the differentiation and maturation of adipocytes , thereby promoting the development of CAD. It indicates that KLF7 may be a potential therapeutic target for cardiovascular diseases (such as CAD) .

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.
