Objective To analyze the pathological types and causes of misdiagnosis of thyroglossal duct cyst(TGDC).Methods The clinical data of 173 patients diagnosed with TGDC before operation in Tangdu Hospital of Air Force Medical University from January 2013 to January 2023 were retrospectively analyzed.Combined with postoperative pathology,a total of 15 patients were found to be misdiagnosed before operation,and the causes of misdiagnosis were summarized.Results The pathological types of 14 misdiagnosed cases in-cluded seven cases of dermoid cyst,three cases of thyroglossal duct papillary carcinoma,one case of accessory thyroid gland,one case of nodular goiter with intracapsular hemorrhage,one case of cervical lymphadenitis and one case of inflammatory nodule.All the 14 patients underwent standard Sistrunk surgery,and regular follow-up after surgery showed no hypothyroidism,recurrence or metastasis.Preoperative static thyroid imaging proved that the neck mass was vago thyroid in one patient,and surgery was not performed to avoid hypothy-roidism or parathyroidism caused by surgery.Conclusion Misdiagnosis of TGDC as other diseases is rare,cli-nicians should raise awareness to avoid the adverse consequences caused by blind operation.

Objective: To analyze the application of digital games for interventions to reduce risky sexual behavior among adolescents, so as to provide a reference for reducing adolescent risky sexual behavior. Methods: The study used PubMed, Web of Science, Cochrane Library, Scopus, Embase, China Biomedical Database, CNKI, Wanfang Database and VIP to carry out a literature search of the application of digital games for interventions aimed at reducing risky sexual behavior among adolescents covering the time period up until February 2024. Results: A total of 10 English articles were included, involving a total of 3 063 adolescents aged 10-24 years old. The publication time spanned from 2013 to 2023. The development and design of the digital games were mostly based on cognitive behavior theory and authentic decision making situations and dialogues. The game participants were divided into single party and multi party categories, mainly using virtual role playing, interactive narrative, and adventure challenges, and there were some differences in content. Digital game intervention had good feasibility and acceptability, which could improve adolescents sexual health knowledge, attitudes, self efficacy, and risk perception, so as to reduce the occurrence of risky behavior. Conclusion As an intervention aimed at reducing risky sexual behavior in adolescents, digital show has significant advantages and can serve as a new prevention and control strategy.

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.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

OBJECTIVE To screen the best compatibility ratio and administration conditions of Panax ginseng -Poria cocos pair against aging ，and investigate its mechanism . METHODS P. ginseng-P. cocos pair extracts with different compatibility ratios （1∶1，1∶2，2∶1，1∶4，4∶1，m/m）were prepared ；taking Saccharomyces cerevisiae as the aging model organism ，the S. cerevisiae growth curve was drawn by MTT method ，the best compatibility ratio ，administration concentration and administration time point of P. ginseng-P. cocos pair were screened out ；the activities of antioxidant related enzymes [superoxide dismutase （SOD），peroxidase （POD），catalase（CAT）]，the levels of reactive oxygen species （ROS）and malondialdehyde （MDA），the content of adenosine triphosphate（ATP），and the mitochondrial membrane potential （MMP）in S. cerevisiae cells were detected ；mRNA expressions of SOD1，CTT1，GSH1，ATP1，MRS1 and CDC 19 were also detected . RESULTS The optimal ratio of P. ginseng-P. cocos pair for anti-aging activity was 1∶4（m/m），the optimal administration concentration was 220 μg/mL，and the optimal administration time point was the 28th hour . The extracts of P. ginseng-P. cocos pair（1∶4，m/m）could significantly increase the activities of SOD ， POD and CAT ，ATP content ，MMP，mRNA expression of CTT 1，GSH1 and MRS 1（P＜0.01），but decrease the levels of MDA and ROS ，mRNA expressions of SOD 1，ATP1 and CDC 19（P＜0.05 or P＜0.01）. CONCLUSIONS P. ginseng-P. cocos pair（1∶4， m/m）has a good anti -aging effect on S. cerevisiae ，its mechanism may be related to the positive regulation of oxidative stress and energy metabolism of S. cerevisiae cell.

OBJECTIVE：To study the potential mechanism of yam protein （DOT） in the prevention and treatment of diabetes-induced erectile dysfunction （DIED）. METHODS ：DIED model was induced by high-glucose and high-fat diet and intraperitoneal injection of streptozotocin （40 mg/kg）. The experiment was set up in the normal control group （normal saline ）， model group （normal saline ），DOT low-dose ，medium-dose and high-dose groups （0.3，0.6，0.9 mg/kg），sildenafil group （positive control ，4.4 mg/kg），with 9 rats in each group. In the stage of successful establishment of diabetes model and initiation of inducing DIED ，rats in each group were given relevant solution intragastrically ，once a day ，for consecutive 11 weeks. Body weight，fasting plasma glucose （FPG），the times and rate of penile erection ，fasting insulin （FINS），insulin resistance index （IR），the contents of endothelial nitric oxide synthase （eNOS）and cyclic guanosine monophosphate （cGMP）in penile cavernous tissue were determined so as to evaluate the intervention effects of DOT on DIED model rats. High-glucose damaged mice cavernous endothelial cells （MCECs）model was induced by 30 mmol/L glucose for 48 h，and then give DOT 125，250，500 μg/mL. The cell viability was detected so as to evaluate the effects of DOT on high-glucose damaged MCECs model. RNA-Seq mail：xingxin0902@163.com technology was adopted to screen the differentially expressed genes between normal MCECs and high-glucose damaged MCECs，high-glucose damaged MCECs and MCECs treated with 250 μg/mL DOT. Gene ontology（GO）function enrichment analysis and KEGG pathway enrichme nt analysis were performed for differentially expressed genes. The common differentially expressed genes between 2 groups were analyzed ，and mRNA expressions of six key genes were validated. RESULTS ：Different doses of DOT could reverse the reduction of body weight ，the increase of FINS and IR ，the reduction of the times and rate of penile erection ，the decrease of eNOS and cGMP contents in penile cavernous tissue of DIED model rats ；above indexes of DIED model rats were reversed significantly after treated with high-dose of DOT（P＜0.05 or P＜0.01）. 125，250，500 μg/L DOT could significantly improve the activity of high-glucose damaged MCECs （P＜0.05 or P＜0.01）. RNA-Seq technology showed that compared with normal MCECs ，a total of 48 differentially expressed genes were found in high-glucose damaged MCECs. Compared with high-glucose damaged MCECs ，a total of 779 differentially expressed genes were found in MCECs treated with DOT. The differentially expressed genes of 2 groups were mainly cellular process in biological process annotation ，cellular part in cell component annotation and binding molecular function in molecular function annotation ，which were mainly enriched in extracellular matrix receptor interaction pathway ，mismatch repair pathway ， phosphatidylinositol 3 kinase-protein kinase B （PI3K-Akt）signal pathway and so on. Among differentially expressed genes of 2 groups，13 common differentially expressed genes such as Aldh1a1，Abcc5，Tac1 were found. DOT could significantly reverse the expression of the above common differentially expressed genes in high-glucose damaged MCECs. After validation ，DOT could significantly reverse the mRNA expression of TGF-β3，Txnip，Aldh1a1，Loxl1，Mt1 and Mt2 in high-glucose damaged MCECs. CONCLUSIONS：DOT could improve the symptom of DIED model rats ，the mechanism of which may be related to biological pathway of inhibiting fibrosis and reducing oxidative stress ，so as to improve the endothelial function of cavernous body.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

OBJECTIVE：To optimi ze the ratio of four comp onents of Compound renshen jianti formulation （Panax ginseng ， Dioscorea oppositifolia ，Lycium barbarum fruit，Alpinia oxyphylla ），and to investigate its anti-fatigue activity and acute toxicity. METHODS：The water extract of Compound renshen jianti formulation was prepared by water extraction ，concentration and decompression drying. By single factor tests ，using weight-bearing swimming time as index ，the effects of four factors were investigated，such as the amount of P. ginseng ，D. oppositifolia ，L. barbarum fruit，A. oxyphylla . On the basis of single factor tests，using comprehensive score of weight-bearing swimming time ，serum urea nitrogen content ，liver glycogen content and AUC of blood lactate after exercise as index ，the formulation was optimized by Box-Behnken response surface method. The mice was divided into blank control group （water），positive control group （Renshen hongjingtian capsules ，0.135 g/kg）and compound low-dose，medium-dose and high-dose groups [the optimal ratio of Compound renshen jianti formulation extract （called“optimal compound formulation ”for short ）4.08，8.16，12.24 g/kg，by crude drug] ，intragastric administration of drug or distilled water 20 mL/kg，once a day ，for consecutive 30 d. The weight-bearing swimming time ，the contents of serum urea nitrogen ，liver glycogen and blood lactate AUC after exercise were used to optimize its anti-fatigue activity of optimal compound formulation. The comprehensive score was calculated based on the measured data of mice in the compound formulation middle-dose group ， and the difference between it and the theoretical prediction value was compared. The mice were given optimal compound formulation intragastrically （total dose 16.00 g/kg， by extract）. The general state ， body mass change ， toxic characteristics and death of mice were observed and recorded for 14 days. Median lethal dose （LD50）and maximum tolerated dose （MTD）were measured. RESULTS ：The optimal formulation ratio of Compound renshen jianti formulation included that P. ginseng 1.5 g，D. oppositifolia 10 g，L. barbarum fruit 10 g，A. oxyphylla 3 g. Results of anti-fatigue activity validation test showed that the optimal compound formulation could significantly prolonged weight-bearing swimming time ，reduced serum content of urea nitrogen ，blood lactate content and its AUC （except for low-dose group ），while significantly increased the content of liver glycogen （P＜0.05 or P＜0.01）. Average comprehensive score of medium-dose group was 96.95，which was only 0.06％ different from the theoretical prediction value of 97.01. The results of acute toxicity test showed that there was no death in mice. The oral MTD of the optimal compound formulation was more than 15 g/kg，which was non-toxic. CONCLUSIONS ：The optimal Compound renshen jianti formulation has effective anti-fatigue activity of mice ，and has no significant toxic effect.

Objective: The aim of this study is to o explore the diagnosis, treatment and prognosis of idiopathic subglottic stenosis （ISS） Method: The clinical data of 15 patients with idiopathic subglottic stenosis treated in our department were analyzed retrospectively. The degree of stenosis was classified by the Cotton Airway grading system of Myer, with 8 cases of gradeⅡ, 4 cases of grade Ⅲ and 3 cases of grade Ⅳ. Result: The time of follow-up of HTSS was 0.5-10 years. All 15 patients were successfully extubated without asphyxia, decannulation and wound nonunion. Conclusion For patients with idiopathic subglottic stenosis in the non-progressive stage, active surgical treatment strategy should be adopted and treated individually. The prognosis is satisfactory.

BACKGROUND: Treatment of coronary bifurcation lesions remains challenging; a simple strategy has been preferred as of late, but the disadvantage is ostium stenosis or even occlusion of the side branch (SB). Only a few single-center studies investigating the combination of a drug-eluting stent in the main branch followed by a drug-eluting balloon in the SB have been reported. This prospective, multicenter, randomized study aimed to investigate the safety and efficacy of a paclitaxel-eluting balloon (PEB) compared with regular balloon angioplasty (BA) in the treatment of non-left main coronary artery bifurcation lesions. METHODS: Between December 2014 and November 2015, a total of 222 consecutive patients with bifurcation lesions were enrolled in this study at ten Chinese centers. Patients were randomly allocated at a 1:1 ratio to a PEB group (n = 113) and a BA group (n = 109). The primary efficacy endpoint was angiographic target lesion stenosis at 9 months. Secondary efficacy and safety endpoints included target lesion revascularization, target vessel revascularization, target lesion failure, major adverse cardiac and cerebral events (MACCEs), all-cause death, cardiac death, non-fatal myocardial infarction, and thrombosis in target lesions. The main analyses performed in this clinical trial included case shedding analysis, base-value equilibrium analysis, effectiveness analysis, and safety analysis. SAS version 9.4 was used for the statistical analyses. RESULTS: At the 9-month angiographic follow-up, the difference in the primary efficacy endpoint of target lesion stenosis between the PEB (28.7% ± 18.7%) and BA groups (40.0% ± 19.0%) was -11.3% (95% confidence interval: -16.3% to -6.3%, Psuperiority <0.0001) in the intention-to-treat analysis, and similar results were recorded in the per-protocol analysis, demonstrating the superiority of PEB to BA. Late lumen loss was significantly lower in the PEB group than in the BA group (-0.06 ± 0.32 vs. 0.18 ± 0.34 mm, P < 0.0001). For intention-to-treat, there were no significant differences between PEB and BA in the 9-month percentages of MACCEs (0.9% vs. 3.7%, P = 0.16) or non-fatal myocardial infarctions (0 vs. 0.9%, P = 0.49). There were no clinical events of target lesion revascularization, target vessel revascularization, target lesion failure, all-cause death, cardiac death or target lesion thrombosis in either group. CONCLUSIONS: In de novo non-left main coronary artery bifurcations treated with provisional T stenting, SB dilation with the PEB group demonstrated better angiographic results than treatment with regular BA at the 9-month follow-up in terms of reduced target lesion stenosis.
