Objective To explore the guiding significance of preoperative 3D reconstruction for pulmonary nodule location and thoracoscopic surgical method selection in lung cancer patients. Methods The clinical data of the patients with preoperative 3D reconstruction in our China-Japan Friendship Hospital between January and November 2023 were retrospectively analyzed. Preoperative surgical planning was performed using 3D reconstruction. Different surgical procedure, including wedge resection, segmentectomy, lobectomy, or combined surgical procedure were performed based on tumor location, size and distance from the pleura. Results A total of 115 patients were included with 45 males and 70 females, at an average age of 25-84 (58.29±11.36) years and successfully completed the operation. Fifty-five (47.8%) patients' nodule diameter was tangent cross-section, among whom twenty-five (21.7%) patients of nodules crossed sections. There were 21 patients of wedge resection in the outer 1/3 nodules of CT, which had shorter operation time and less cost (P<0.001) and less intraoperative bleeding (P=0.019). For the crossing sections or edge crossing sections nodules of the middle and inner of CT, 6 patients were of simple pulmonary segmentectomy, 8 patients of combined with sub-segmentectomy, 7 patients of combined segmentectomy, 5 patients of lobectomy, and 3 patients of wedge resection. Conclusion The proportion of cross-segment pulmonary nodules is relatively high. For the outer 1/3 nodules of CT, compared with pulmonary segmental resection combined with adjacent lung tissue resection, wedge resection can also ensure sufficient surgical margin, and the middle and inner 1/3 nodules of CT need to be combined with adjacent pulmonary tissue resection to ensure the surgical edge.

Objective To evaluate the efficacy of oxycodone in analgesia after thoracoscopic radical lung cancer surgery in elderly.Methods A total of 92 elderly patients who underwent thoracoscopic radical lung cancer surgery in the Affiliated Shuyang Hospital of Xuzhou Medical University were selected and randomly divided into the control group and the observation group according to the random number table method,with 46 cases in each group.Postoperative analgesia was administered with self-controlled intravenous analgesia pump for patients.Patients in the control group was anesthetized with sufentanil 2 μg/kg+dexmedetomidine 0.5 μg/kg,and patients in the observation group was anesthetized with oxycodone 0.5 mg/kg+dexmedetomidine 0.5 μg/kg.The pain degree,delirium,inflammatory factor level,cognitive function at different time points and postoperative adverse reactions of patients were compared between the two groups.Results The pain scores of patients 12 hours,24 hours and 48 hours after surgery in the observation group were significantly lower than those in the control group(P<0.05).The incidence of postoperative adverse reactions in the observation group was significantly lower than that in the control group(P<0.05).The levels of S100β,NSE and TNF-α of patients 1 day and 2 days after surgery in the observation group were significantly lower than those in the control group(P<0.05).The cognitive function scores of patients 1 day and 2 days after surgery in the observation group were significantly higher than those in the control group(P<0.05).The incidences of delirium 1 day,2 days and 3 days after surgery in the observation group were significantly lower than those in the control group(P<0.05).Conclusion The use of oxycodone for postoperative self-controlled intravenous analgesia in elderly patients after radical lung cancer surgery can significantly relieve pain,reduce analgesia-related adverse reactions and the incidence of postoperative delirium,decrease the inflammatory factors levels,and alleviate the degree of cognitive function impairment,which is beneficial to the postoperative recovery of patients.

On the basis of the laboratory detection results of influenza viruses in Jiangsu Province from 2022 to 2023,this study was aimed at conducting a analysis of the genetic characteristics and resistance of the H3N2 influenza virus,and evalua-ting the effectiveness of vaccines and drugs.The full genome of 29 H3N2 isolates submitted by provincewide influenza surveil-lance network laboratories was amplified and sequenced.Phylogenetic trees of the HA and NA genes were constructed.The mutation characteristics of antigenic sites,glycosylation sites,and resistance sites were analyzed,and the influenza virus neura-minidase was detected with a fluorescence luminescence method.The homology of the 29 H3N2 isolates in Jiangsu Province was relatively high.The isolates belonged to the same evolutionary branch as domestic reference strains and the 2021-2022 vaccine strains,but were in different evolutionary branches from foreign reference strains and the 2022-2023 vaccine strains.Compared with the 2021-2022 vaccine strain A/Cambodia/e0826360/2020,the H3N2 influenza viruses isolated in Jiangsu Province during 2022-2023 had four amino acid substitutions in the HA protein and two amino acid substitutions in the NA protein.No changes in glycosylation sites,receptor-binding sites,and conserved amino acid residue regions were observed.IC50 analysis indicated that the 29 H3N2 isolates were not resistant to the antiviral drugs oseltamivir and zanamivir.The pre-dominant influenza viruses detected in Jiangsu Province during 2022-2023 were type A H3N2 influenza viruses.Monitoring of variations in HA and NA gene sites and influenza virus resistance aids in rapid understanding gene mutations,and can inform the selection of effective vaccine strains,and contribute to the prevention and control of influenza virus outbreaks.

Purpose To explore the value of contrast-enhanced ultrasound(CEUS)in the differential diagnosis of gallbladder polypoid lesions(GPLs)(diameter≥10 mm).Materials and Methods A prospective enrollment of 229 patients with GPLs who underwent cholecystectomy in 17 hospitals from December 1 2021 to June 30 2024 was conducted to analyze the relationship between general data,conventional ultrasound,CEUS characteristics and the nature of GPLs.Multivariate Logistic regression was employed to identify independent risk factors for neoplastic polyps,the differential diagnostic value of different indicators was compared.Results Among 229 patients with GPLs,there were 108 cases of cholesterol polyps,102 cases of adenoma and 19 cases of gallbladder cancer.Age(Z=-4.476,P<0.001),polyp number(χ2=15.561,P<0.001),diameter(Z=-8.149,P<0.001),echogenicity(χ2=9.241,P=0.010),vascularity(χ2=23.107,P<0.001),enhancement intensity(χ2=47.610,P<0.001),enhancement pattern(χ2=6.468,P=0.011),vascular type(χ2=84.470,P<0.001),integrity of gallbladder wall(χ2=7.662,P=0.006)and stalk width(Z=-9.831,P<0.001)between cholesterol polyps and neoplastic polyps were statistically significant.Age,location,diameter,echogenicity,enhancement pattern,vascular type and stalk width between adenoma and gallbladder cancer were statistically significant(Z=-4.333,-3.902,-5.042,all P<0.05).Multivariate Logistic regression analysis showed that hyper-enhancement,branched vascular type and stalk width were independent risk factors for neoplastic polyps(OR=4.563,5.770,3.075,all P<0.001).The combination of independent risk factors was better than single factor and diameter in the differential diagnosis of cholesterol polyps and neoplastic polyps(all P<0.01).Conclusion CEUS can effectively identify the nature of GPLs and provide a valuable imaging reference for the selection of treatment methods.

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 explore whether lung microorganisms influence the occurrence and development of early lung adenocarcinoma by analyzing the presence and changes of local microorganisms in early lung adenocarcinoma.Methods:Tumor tissues and alveolar lavage fluid were collected from 32 patients diagnosed with lung adenocarcinoma at the China-Japan Friendship Hospital. Nextseq550DX was used for DNA sequencing. R language was used to calculate the number of microorganisms in the tumor tissue and alveolar lavage fluid samples of different stages and grades. species and diversity, and use statistical methods such as TSEA and LEfSe analysis to compare the diversity and differences of microorganisms in different groups. Results:Both Actinobacteria and Proteobacteria accounted for a higher proportion in both the tumor tissue and alveolar lavage fluid samples of patients with lung adenocarcinoma. The number of microorganisms detected in the tumor tissue was greater than that in the lavage fluid, and the alpha diversity was higher, but the difference Not significant( P<0. 05). According to the analysis of differences in lung microorganisms in patients with different pathological grades: In the two samples, invasive adenocarcinoma has more microorganisms than carcinoma in situ + microinvasive carcinoma, and the alpha diversity of the lavage fluid is significantly higher, and the comparison between the groups is statistically significant( P=0. 011); the difference in β diversity was not statistically significant( P>0. 05). Group analysis based on different pathological types: the invasive adenocarcinoma group samples showed a decrease in Proteobacteria, the carcinoma in situ + minimally invasive cancer group was mainly composed of Proteobacteria, and most of the microorganisms related to lung cancer differences analyzed in each group belonged to Proteobacteria and Actinobacteria. Phylum. Conclusion:Most of the microbes in tumor tissues and lavage fluid of lung adenocarcinoma belong to the Actinobacteria and Proteobacteria. Most of the differentially associated microbes of lung cancer under different classifications also belong to Proteobacteria and Actinobacteria, which are the main characteristics of lung microbial composition in patients with early-stage lung adenocarcinoma.

Chronic heart failure(CHF) has become a worldwide public health problem due to its high morbidity and mortality, which seriously endangers people's lifespan and quality of life. In recent years, the treatment strategy of CHF has shifted its emphasis on short-term improvement and transformation of hemodynamics to long-term repair as well as improvement of the biological properties of heart failure. At present, with the continuous deepening of medical research, it has been found that histone acetylation is closely related to the occurrence and development of CHF. Traditional Chinese medicine, via regulating histone acetylation, delays ventricular remodeling, improves energy metabolism, inhibits fibrosis and cardiomyocyte hypertrophy, and intervenes in the development process of heart failure, thus reducing the mortality and the readmission rate and ultimately improving long-term prognosis. Therefore, this study reviewed the mechanism of histone acetylation in the treatment of heart failure as well as its prevention and treatment with traditional Chinese medicine, to provide reference for clinical treatment of CHF.

Objective: To investigate the influence of sleep fragmentation in infancy and toddler period on emotional and behavioral problems at the age of 6 years. Methods: Using a prospective cohort design, 262 children were extracted from mother-child birth cohort recruited from May 2012 to July 2013 in Renji Hospital, School of Medicine, Shanghai Jiao Tong University. Children's sleep and physical activities were assessed using actigraphy at 6, 12, 18, 24, and 36 months of age, from which the sleep fragmentation index (FI) at each follow-up point was calculated. Children's emotional and behavioral problems at 6 years of age were assessed using the strengths and difficulties questionnaire. Group-based trajectory model was applied to determine sleep FI in infancy and toddler period trajectory groups with Bayesian information criteria being used to determine the best fitting model. Children's emotional and behavioral problems between groups were examined with independent t test and linear regression models, etc. Results: A total of 177 children, with 91 boys and 86 girls, were included in the final analysis and were divided into 2 groups: high FI group (n=30) and low FI group (n=147). Compared with children in the low FI group, those in the high FI group presents with higher total difficulties score and higher hyperactivity or inattention score ((11.0±4.9) vs. (8.9±4.1), (4.9±2.7) vs. (3.7±2.3) scores, t=2.17, 2.23, both P<0.05, respectively), with the differences remaining significant after adjusting for covariates (t=2.08, 2.09, both P<0.05 respectively). Conclusion: High sleep fragmentation in infancy and toddler period is associated with more emotional and behavioral problems, especially hyperactivity or inattention problems, at 6 years of age.

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.
