Objective To dynamically observe the changes in hypoxia-inducible factor 1α(HIF-1α)and Bcl-2/adenovirus E1B19kDa-interacting protein 3(BNIP3)in children with traumatic brain injury(TBI)and evaluate their clinical value in predicting the severity and prognosis of pediatric TBI.Methods A prospective study included 47 children with moderate to severe TBI from January 2021 to July 2023,categorized into moderate(scores 9-12)and severe(scores 3-8)subgroups based on the Glasgow Coma Scale.A control group consisted of 30 children diagnosed and treated for inguinal hernia during the same period,with no underlying diseases.The levels of HIF-1α,BNIP3,autophagy-related protein Beclin-1,and S100B were compared among groups.The predictive value of HIF-1α,BNIP3,Beclin-1,and S100B for the severity and prognosis of TBI was assessed using receiver operating characteristic(ROC)curves.Results Serum levels of HIF-1α,BNIP3,Beclin-1,and S100B in the TBI group were higher than those in the control group(P＜0.05).Among the TBI patients,the severe subgroup had higher levels of HIF-1α,BNIP3,Beclin-1,and S100B than the moderate subgroup(P＜0.05).Correlation analysis showed that the serum levels of HIF-lα,BNIP3,Beclin-1,and S100B were negatively correlated with the Glasgow Coma Scale scores(P＜0.05).After 7 days of treatment,serum levels of HIF-1α,BNIP3,Beclin-1,and S100B in both non-surgical and surgical TBI patients decreased compared to before treatment(P＜0.05).ROC curve analysis indicated that the areas under the curve for predicting severe TBI based on serum levels of HIF-1α,BN1P3,Beclin-1,and S100B were 0.782,0.835,0.872,and 0.880,respectively(P＜0.05),and for predicting poor prognosis of TBI were 0.749,0.775,0.814,and 0.751,respectively(P＜0.05).Conclusions Serum levels of HIF-1α,BNIP3,and Beclin-1 are significantly elevated in children with TBI,and their measurement can aid in the clinical assessment of the severity and prognosis of pediatric TBI.IChinese Journal of Contemporary Pediatrics,2024,26(4):378-384]

Objective With the assistance of 3D visualization and real-time navigation technologies,the tumors in the parapharyngeal and lateral skull base should be removed through oral the approach with endoscopy.Methods The preoperative CT data of eight patients with parapharyngeal or lateral skull base soft tissue tumors were modeled,and the anatomical position relationship between the tumor and surrounding blood vessels and other important structures was re-constructed using 3D visualization technology,and preop-erative design was performed.The intraoperative oral ap-proach and real-time navigation guidance were adopted in the endoscopic resection of soft tissue tumors in the parapharyngeal and lateral skull base,and the clinical ap-plication value of this method was evaluated.Results The blood loss during the operation was controlled within 150 mL,and the average blood loss was approximately 125 mL.The incidence of postoperative complications was low,and patients could recover well through functional training.The oral approach did not leave any wounds nor scars on the patient's facial skin after the operation and had no effect on the patient's appearance.Conclusion The combination of 3D visualization technology,intraoperative real-time navigation,and endoscopy provides a beautiful,safe,and minimally invasive surgical method for patients with parapharyngeal or lateral skull base tumors.

OBJECTIVE To evaluate the clinical effectiveness and safety of domestic generic and imported original clopidogrel for antiplatelet therapy in patients with acute coronary syndrome （ACS）. METHODS The clinical data of ACS patients in Nanjing Drum Tower Hospital of China Pharmaceutical University from January 2020 to June 2021 were retrospectively collected by using electronic medical record system， and the patients were divided into original drug group （321 cases） and generic drug group （328 cases） according to the drug use. Both groups were given dual antiplatelet therapy with clopidogrel and aspirin. The effectiveness and safety outcomes of the two groups were followed up for 12 months and compared， the related influential factors were analyzed. RESULTS Major adverse cardiovascular events （MACE） occurred in 16 and 22 patients in original drug group and generic drug group respectively， including nonfatal myocardial infarction （4 and 5 cases）， stroke （2 and 4 cases）， revascularization （8 and 3 cases）， cardiovascular related death （2 and 4 cases）， and all-cause death （4 and 6 cases）. There were 12 and 7 patients with major bleeding events， 38 and 29 patients with minor bleeding events， and 33 and 21 patients with non-bleeding adverse events. There was no statistically significant difference in the cumulative incidence of related events （P values of Log-Rank tests were all greater than 0.05）. Cox regression analysis showed that the use of generic clopidogrel did not increase the risk of MACE and major bleeding events in ACS patients [hazard ratio of 1.305 and 0.416， 95% confidence interval of （0.678， 2.512） and （0.155， 1.117）， respectively， P＞0.05]， and the combination of proton pump inhibitors （PPI） could reduce the risk of major bleeding events [hazard ratio of 0.196， 95% confidence interval of （0.063， 0.611）， P＜0.05]. CONCLUSIONS Compared with imported original drug， domestic generic clopidogrel has similar clinical effectiveness and good safety. Combined use of PPI may be a beneficial factor to reduce the occurrence of major bleeding events in patients.

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.

This study followed up the immune memory after 3-dose revaccination among infants with non-and low-response following primary hepatitis B (HepB) vaccination. About 120 children without self-booster doses were finally included who had anti-HBs<10 mIU/ml (anti-HBs negative) at the time of follow-up, of whom 86 children completed blood sampling and anti-HBs testing. Before the challenge dose, all 86 children were negative for anti-HBs, and the GMC of anti-HBs was<10 mIU/ml. The seropositive conversion rate of anti-HBs was 100% and the GMC of anti-HBs was 886.11 (95%CI: 678.15-1 157.84) mIU/ml after the challenge dose. Compared with those with GMC<7 mIU/ml before the challenge dose, infants with GMC>7 mIU/ml had a higher anti-HBs level after the challenge dose. The β value (95%CI) was 0.82 (0.18-1.46) (P=0.012). Compared with those with GMC<1 000 mIU/ml at primary vaccination, infants with GMC≥1 000 mIU/ml had a higher anti-HBs level after the challenge dose. The β value (95%CI) was 0.78 (0.18-1.38)(P=0.012). The results showed a stronger immune memory was found at 9 years after revaccination among infants with non-and low-response to HepB.

Objective: To analyze the survival time of reported HIV/AIDS and influencing factors of Yunnan Province from 1989 to 2021. Methods: The data were extracted from the Chinese HIV/AIDS comprehensive response information management system. The retrospective cohort study was conducted. The life table method was applied to calculate the survival probability. Kaplan-Meier was used to draw survival curves in different situations. Furthermore, the Cox proportion hazard regression model was constructed to identify the factors related to survival time. Results: Of the 174 510 HIV/AIDS, the all-cause mortality density was 4.23 per 100 person-years, the median survival time was 20.00 (95%CI:19.52-20.48) years, and the cumulative survival rates in 1, 10, 20, and 30 years were 90.75%, 67.50%, 47.93% and 30.85%. Multivariate Cox proportional risk regression model results showed that the risk of death among 0-14 and 15-49 years old groups were 0.44 (95%CI: 0.34-0.56) times and 0.51 (95%CI:0.50-0.52) times of ≥50 years old groups. The risk for death among the first CD4⁺T lymphocytes counts (CD4) counts levels of 200-349 cells/μl, 350-500 cells/μl and ≥501 cells/μl groups were 0.52 (95%CI: 0.50-0.53) times, 0.41 (95%CI: 0.40-0.42) times and 0.35 (95%CI: 0.34-0.36) times of 0-199 cells/μl groups. The risk of death among the cases that have not received antiretroviral therapy (ART) was 11.56 (95%CI: 11.26-11.87) times. The risk for death among the cases losing to ART, stopping to ART, both losing and stopping ART was 1.66 (95%CI:1.61-1.72) times, 2.49 (95%CI:2.39-2.60) times, and 1.65 (95%CI:1.53-1.78) times of the cases on ART. Conclusions: The influencing factors for the survival time of HIV/AIDS cases were age at diagnosis in Yunnan province from 1989 to 2021.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Objective:To explore the risk factors for the occurrence of thrombocytopenia (TCP) within 2 weeks after pediatric liver transplantation (LT) and examine the relationship between the occurrence of TCP and prognosis.Methods:From January 2021 to November 2021, clinical data were retrospectively reviewed for 162 pediatric LT recipients aged under 4 years at Organ Transplantation Center of Tianjin First Central Hospital.Based upon the lowest value of platelet count at Week 2 post-operation, they were assigned into two groups of TCP (n=90) and non-TCP (n=72). General preoperative profiles, intraoperative findings, postoperative complications, types of commonly used antibiotics, anticoagulant dosing and prognosis of two groups were compared.Univariate and multivariate analyses were utilized for examining the independent risk factors for TCP.Receiver operating characteristic (ROC) curve was plotted for examining the cut-off value of independent risk factors for diagnosing TCP.Results:Among them, 90 (55.56%) developed TCP within 2 weeks post-operation and 25(15.43%) developed TCP at Day 1 post-operation.The median preoperative platelet count was 178×10 9/L and the lowest value was 65×10 9/L at Day 3(1-4) post-operation with a declining rate of 63.5% and platelet count of recipient normalized at Day 6(4-7.25) post-operation.The results of univariate analysis showed statistically significant inter-group differences in operative duration[(574.43±80.53)min vs.(526.75±72.42)min], intraoperative blood loss[400(300, 550)ml vs.320(300, 400)ml], red blood cell transfusion[2(2, 3)U vs.2(1.5, 2.0)U], preoperative platelet count[178.5(141.75, 242.5)×10 9/L vs.257 (209.75, 357)×10 9/L], postoperative infection rate[27.8%(25/90)vs.13.9%(10/72)] and dosing rates of piperacillin sodium and tazobactam sodium[8.9%(8/90)vs.25.0%(18/72)] ( P<0.05). Multivariate Logistic regression analysis revealed statistically significant inter-group differences in operative duration( P=0.008), red blood cell transfusion( P=0.01), preoperative platelet count( P<0.01) and postoperative infection rate ( P=0.02). The results of ROC curve analysis showed that the cut-off values of operative duration, red blood cell transfusion and preoperative platelet count were 535 min, 2.75 U and 183.5×10 9/L respectively.Length of ICU stay was higher in TCP group than that in non-TCP group, and the difference was statistically significant [4(3, 5) vs.3(3, 4) day, P=0.006]. Conclusions:LT children aged under 4 years with intraoperative red blood cell transfusion>2.75 U, operative duration>535 min and preoperative platelet count<183.5×10 9/L are more likely to develop post-transplantation TCP.And occurrence of TCP prolongs the length of ICU stay in pediatric recipients.
