Objective To explore clinical effect of closed reduction percutaneous elastic intramedullary nail assisted by arthrography in the treatment of radial neck fracture in children.Methods A retrospective analysis was performed on 23 chil-dren with radial neck fracture treated with arthrography assisted closed reduction and percutaneous elastic intramedullary nail internal fixation(arthrography with elastic nail group)from January 2019 to December 2022,including 12 males and 11 fe-males,aged from 2 to 12 years old with an average of(7.36±1.89)years old;According to Judet fracture types,14 children were type Ⅲ and 9 children were type Ⅳ.In addition,23 children with radial neck fracture were selected from January 2015 to December 2018 who were treated with closed reduction and percutaneous elastic intramedullary nail fixation(elastic nail group),including 11 males and 12 females,aged from 2 to 14 years old with an average of(7.50±1.91)years old;Judet classi-fication included 15 children were type Ⅲ and 8 children were type Ⅳ.Operative time and intraoperative fluoroscopy times were compared between two groups.Metaizeau evaluation criteria was used to evaluate fracture reduction,and Tibone-Stoltz evaluation criteria was used to evaluate functional recovery of elbow between two groups.Results Both groups were followed up for 12 to 24 months with an average of(16.56±6.34)months.Operative time and intraoperative fluoroscopy times of elastic nail group were(56.64±19.27)min and(21.13±7.87)times,while those of joint angiography with elastic nail group were(40.33±1 1.50)min and(12.10±3.52)times;there were difference between two groups(P＜0.05).According to Metaizeau evaluation,11 patients got excellent result,9 good and 3 fair in joint angiography with elastic nail group,while in elastic nail group,5 ex-cellent,13 good,4 acceptable,and 1 poor;the difference between two groups was statistically significant(P＜0.05).According to Tibone-Stoltz criteria,14 patients got excellent result,8 good,and 1 fair in joint arthrography with elastic nail group;while in elastic nail group,12 patients got excellent result,9 good,1 fair and 1 poor;there was no significant difference between two groups(P＞0.05).Conclusion Compared to percutaneous elastic intramedullary nail fixation,closed reduction assisted by arthrography has advantages of reduced operation time,decreased intraoperative fluoroscopy frequency,and improved fracture reduction.Arthrography enables clear visualization of the anatomical structures of radius,head,neck,bone,and cartilage in children,facilitating comprehensive display of fracture reduction and brachioradial joint alignment.This technique more pre-cisely guides the depth of elastic intramedullary nail implantation in radius neck,thereby enhancing surgical efficiency and success rate.

Background: Triglyceride glucose (TyG) and TyG-body mass index (TyG-BMI) are reliable surrogate indices of insulin resistance and used for risk stratification and outcome prediction in patients with atherosclerotic cardiovascular disease (ASCVD). Here, we inserted estimated average glucose (eAG) into the TyG (TyAG) and TyG-BMI (TyAG-BMI) as derived parameters and explored their clinical significance in cardiovascular risk prediction. Methods: This was a population-based cohort study of 9,944 Chinese patients with ASCVD. The baseline admission fasting glucose and A1C-derived eAG values were recorded. Cardiovascular events (CVEs) that occurred during an average of 38.5 months of follow-up were recorded. We stratified the patients into four groups by quartiles of the parameters. Baseline data and outcomes were analyzed. Results: Distribution of the TyAG and TyAG-BMI indices shifted slightly toward higher values (the right side) compared with TyG and TyG-BMI, respectively. The baseline levels of cardiovascular risk factors and coronary severity increased with quartile of TyG, TyAG, TyG-BMI, and TyAG-BMI (all P<0.001). The multivariate-adjusted hazard ratios for CVEs when the highest and lowest quartiles were compared from low to high were 1.02 (95% confidence interval [CI], 0.77 to 1.36; TyG), 1.29 (95% CI, 0.97 to 1.73; TyAG), 1.59 (95% CI, 1.01 to 2.58; TyG-BMI), and 1.91 (95% CI, 1.16 to 3.15; TyAG-BMI). The latter two showed statistical significance. Conclusion This study suggests that TyAG and TyAG-BMI exhibit more information than TyG and TyG-BMI in disease progression among patients with ASCVD. The TyAG-BMI index provided better predictive performance for CVEs than other parameters.

Objective To investigate the predictive value of Glasgow coma scale(GCS)-Full Out-line of UnResponsiveness(FOUR)scale(GCS-F)score and arterial lactate level for prognosis of intracerebral hemorrhage(ICH)in elderly patients.Methods A total of 278 elderly ICH patients admitted to Neurosurgical Intensive Care Unit of the Affiliated Hospital of North China Universi-ty of Science and Technology from January 2022 to January 2024 were retrospectively recruited.According score at 90 d after onset,95 of them were assigned into good prognosis group and 183 into poor prognosis group.Basic information,vital signs at admission,pupils,laboratory indica-tors,GCS score and other clinical data were compared between the two groups.Binary logistic re-gression analysis was used to analyze the risk factors of poor prognosis in elderly ICH patients.ROC curve was drawn to analyze the prognostic value of GCS-F score(including eye opening re-sponse and limb movement in GCS,and brainstem response in FOUR scale)combined with lac-tate level in elderly ICH patients.Results Significantly higher blood pressure,elevated levels of blood glucose,creatinine and arterial lactic acid,increased percentages of supratentorial and sub-tentorial bleeding,and larger blood loss,while obviously lower GCS score and GCS-F score were observed in the poor prognosis group than the good prognosis group(P＜0.05,P＜0.01).In the analyses for poor prognosis rate of ICH patients at different levels,the poor prognosis rate of se-vere GCS-F patients was significantly higher than that of patients with same level of GCS score(P＜0.05).Binary logistic regression analysis showed that GPS-F score(OR=1.762,95％CI:1.507-2.061,P=0.000)and arterial lactate level(OR=0.536,95％CI:0.385-0.746,P=0.000)were risk factors for 90-day poor prognosis in elderly ICH patients.ROC curve analysis indicated that the AUC value of arterial lactate,GCS score and GCS-F score in predicting 90-day poor prog-nosis in elderly ICH patients was 0.713(95％CI:0.650-0.775),0.827(95％CI:0.774-0.880)and 0.876(95％CI:0.828-0.925),respectively,and the AUC value of GCS-F score combined with arterial lactic acid was 0.919(95％CI:0.886-0.953),which was significantly higher than that of GCS score,GCS-F score and arterial lactic acid alone(P＜0.01).Conclusion GCS-F score has better performance than GCS score in predicting 90-day poor prognosis in elderly ICH pa-tients,especially for severe patients.The GPS-F score combined with arterial lactate level shows the best predictive effectiveness for elderly ICH patients.

Optimal blood pressure (BP) management is crucial for preventing these complications. This review consolidates evidence from clinical trials and major BP management guidelines to shed light on key aspects of hypertension management in diabetes. It addresses BP thresholds to initiate antihypertensive treatment, optimal BP control targets, recommended first-line antihypertensive edications, and BP monitoring plan for the prevention of chronic complications in type 2 diabetes.

Objective:To evaluate the effect of autologous hematopoietic stem cell transplantation (ASCT) on the treatment of relapsed/refractory multiple myeloma (RRMM) with chimeric antigen receptor T cell (CAR-T) therapy.Methods:A retrospective cohort study. The clinical data of 168 patients with RRMM who underwent CAR-T therapy at the Department of Hematology, Xuzhou Medical University Hospital from 3 January 2020 to 13 September 2022 were analyzed. Patients were classified into a transplantation group (TG; n=47) and non-transplantation group (NTG; n=121) based on whether or not they had undergone ASCT previously. The objective response rate (ORR), progression-free survival (PFS), overall survival (OS) and the levels of CD3, CD4, CD8, CD19, CD56 and natural killer (NK) cells before CAR-T infusion were analyzed by χ2 test, Kaplan-Meier method and independent sample t-test. Results:Among 168 patients with RRMM, 98 (58.3%) were male. The median age of onset was 57 (range 30-70) years. After CAR-T therapy, the ORR of patients was 89.3% (92/103) in the NTG and 72.9% (27/73) in the TG. The ORR of the NTG was better than that of the TG ( χ2=5.71, P=0.017). After 1 year of CAR-T therapy, the ORR of the NTG was 78.1% (75/96), and that of the TG was 59.4% (19/32). The ORR of the NTG was better than that of the TG ( χ2=4.32, P=0.038). The median OS and PFS in the NTG were significantly longer than those in the TG (OS, 30 vs. 20 months; PFS, 26 vs. 12 months; both P<0.05). The CD4 level before CAR-T infusion in the TG was significantly lower than that in the NTG (25.65±13.56 vs. 32.64±17.21; t=-2.15, P=0.034), and there were no significant differences in the counts of CD3, CD8, CD19, CD56, and NK cells between the TG and NTG (all P>0.05). Conclusion:Among patients suffering from RRMM who received CAR-T therapy, patients who did not receive ASCT had significantly better outcomes than those who had received ASCT previously, which may have been related to the CD4 level before receiving CAR-T therapy.

Objective:To investigate the effectiveness and prognosis of using improved domestic neonatal ureteral stents (referred to as improved double-J stents) for thoraco-amniotic shunting (TAS) in treating fetal chylothorax.Methods:A retrospective analysis was conducted on the clinical data of 21 cases of fetal chylothorax treated with TAS using improved double-J stents at Nanjing Drum Tower Hospital, Nanjing University Medical School from April 1, 2018, to September 30, 2023. Surgical complications and perinatal outcomes were summarized, and the development of surviving infants in five domains (communication, gross motor, fine motor, problem-solving, and personal-social) was assessed using the Ages and Stages Questionnaires-Third Edition (ASQ-3). Descriptive statistical analysis was used. Results:(1) The median gestational age at prenatal diagnosis was 28.7 weeks (27.3-30.4 weeks), with 85.7% (18/21) of cases complicated by fetal hydrops, 90.5% (19/21) by polyhydramnios, and 85.7% (18/21) by bilateral pleural effusion. (2) The median gestational age at the first TAS was 30.9 weeks (29.7-32.7 weeks). Of the 21 cases, 10 required repeat stent placement due to dislodgement or blockage, with a total of 49 stent placements. The dislodgement rate within 7 days was 24.5% (12/49), and the blockage rate was 16.3% (8/49). The rate of premature rupture of membranes within one week post-stent placement was 9.5% (2/21), with an overall preterm premature rupture of membranes rate of 28.6% (6/21). The median interval from the first TAS to delivery was 30.0 d (19.8-40.0 d). Of the 21 cases, three opted for selective termination of pregnancy; the remaining 18 cases resulted in live births, with a median gestational age at delivery of 35.6 weeks (34.1-37.1 weeks), and three neonatal deaths. The overall neonatal survival rate was 15/18. Surviving infants were followed up to a median age of 30 months (7-48 months), with 13 showing normal development and two scoring below the ASQ-3 threshold.Conclusion:The improved double-J stent can be used for TAS in the treatment of fetal chylothorax, with generally favorable outcomes.

Objective:To investigate the surgical situations and perioperative outcome of pancreaticoduodenectomy in Jiangsu Province and the influencing factors for postoperative 90-day mortality.Methods:The retrospective case-control study was conducted. The clinicopathological data of 2 886 patients who underwent pancreaticoduodenectomy in 21 large tertiary hospitals of Jiangsu Quality Control Center for Pancreatic Diseases, including The First Affiliated Hospital of Nanjing Medical University, from March 2021 to December 2022 were collected. There were 1 732 males and 1 154 females, aged 65(57,71)years. Under the framework of the Jiangsu Provincial Pancreatic Disease Quality Control Project, the Jiangsu Quality Control Center for Pancreatic Diseases adopted a multi-center registration research method to establish a provincial electronic database for pancrea-ticoduodenectomy. Observation indicators: (1) clinical characteristics; (2) intraoperative and post-operative conditions; (3) influencing factors for 90-day mortality after pancreaticoduodenectomy. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(IQR), and comparison between groups was conducted using the Mann-Whitney U test. Count data were expressed as absolute numbers or constituent ratio, and comparison between groups was conducted using the chi-square test, continuity correction chi-square test and Fisher exact probability. Maximal Youden index method was used to determine the cutoff value of continuous variables. Univariate analysis was performed using the corresponding statistical methods based on data types. Multivariate analysis was performed using the Logistic multiple regression model. Results:(1) Clinical characteristics. Of the 2 886 patients who underwent pancreaticoduodenectomy, there were 1 175 and 1 711 cases in 2021 and 2022, respectively. Of the 21 hospitals, 8 hospitals had an average annual surgical volume of <36 cases for pancreaticoduodenectomy, 10 hospitals had an average annual surgical volume of 36-119 cases, and 3 hospitals had an average annual surgical volume of ≥120 cases. There were 2 584 cases performed pancreaticoduodenectomy in thirteen hospitals with an average annual surgical volume of ≥36 cases, accounting for 89.536%(2 584/2 886)of the total cases. There were 1 357 cases performed pancrea-ticoduodenectomy in three hospitals with an average annual surgical volume of ≥120 cases, accounting for 47.020%(1 357/2 886) of the total cases. (2) Intraoperative and postoperative conditions. Of the 2 886 patients, the surgical approach was open surgery in 2 397 cases, minimally invasive surgery in 488 cases, and it is unknown in 1 case. The pylorus was preserved in 871 cases, not preserved in 1 952 cases, and it is unknown in 63 cases. Combined organ resection was performed in 305 cases (including vascular resection in 209 cases), not combined organ resection in 2 579 cases, and it is unknown in 2 cases. The operation time of 2 885 patients was 290(115)minutes, the volume of intra-operative blood loss of 2 882 patients was 240(250)mL, and the intraoperative blood transfusion rate of 2 880 patients was 27.153%(782/2 880). Of the 2 886 patients, the invasive treatment rate was 11.342%(327/2 883), the unplanned Intensive Care Unit (ICU) treatment rate was 3.087%(89/2 883), the reoperation rate was 1.590%(45/2 830), the duration of postoperative hospital stay was 17(11)days, the hospitalization mortality rate was 0.798%(23/2 882), and the failure rate of rescue data in 2 083 cases with severe complications was 6.529%(19/291). There were 2 477 patients receiving postoperative 90-day follow-up, with the 90-day mortality of 2.705%(67/2477). The total incidence rate of complication in 2 886 patients was 58.997%(1 423/2 412). The incidence rate of severe complication was 13.970%(291/2 083). The comprehensive complication index was 8.7(22.6) in 2 078 patients. (3) Influencing factors for 90-day mortality after pancreaticoduodenectomy. Results of multivariate analysis showed that age ≥ 70 years, postoperative invasive treatment, and unplanned ICU treatment were independent risk factors for 90-day mortality after pancreaticoduodenectomy ( odds ratio=2.403, 2.609, 16.141, 95% confidence interval as 1.281-4.510, 1.298-5.244, 7.119-36.596, P<0.05). Average annual surgical volume ≥36 cases in the hospital was an independent protective factor for 90-day mortality after pancreaticoduodenectomy ( odds ratio=0.368, 95% confidence interval as 0.168-0.808, P<0.05). Conclusions:Pancreaticoduodenectomy in Jiangsu Province is highly con-centrated in some hospitals, with a high incidence of postoperative complications, and the risk of postoperative 90-day mortality is significant higher than that of hospitallization mortality. Age ≥ 70 years, postoperative invasive treatment, and unplanned ICU treatment are independent risk factors for 90-day motality after pancreaticoduodenectomy, and average annual surgical volume ≥36 cases in the hospital is an independent protective factor.

Objective To prepare Zishen pills as gel plaster according to the prescription,and investigate its transdermal absorption characteristics in vitro.Methods Based on preliminary experiments,the matrix prescription of the gel plaster was optimized by single-factor tests and the Box-Behnken design.Evaluation indicators included initial viscosity,viscosity retention and sensory scores.The modified Franz diffusion cell was used to investigate the effect of penetration enhancers on the transdermal characteristics of gel plaster in vitro,with the permeability of neomangiferin,phellodendrine hydrochloride,mangiferin and berberine hydrochloride as evaluation indicators.Results The prescription dosage of the preferred matrix for the Zishen gel plaster was sodium polyacrylate NP700 2.55 g,glycerin 11.04 g,polyvinylpyrrolidone K90 1.13 g,tartaric acid 0.1 g,glycyrrhizin 0.1 g,kaolin 0.3 g,and distilled water 15 g.Among different types and concentrations of permeation enhancers,5%aminoketone showed the best permeation performance.The permeation rates for neomangiferin,phellodendrine hydrochloride,mangiferin,and berberine hydrochloride were 1.5338,1.7809,2.3247 and 20.0899 μg·(cm2)-1·h-1,and the penetration rates were 2.4319,1.9408,1.9604 and 1.4701,respectively.The percutaneous absorption curve of the drug conformed to the zero-order kinetic equation.Conclusion The preparation process of the obtained gel plaste is stable and feasible,with good adhesive properties,sustained drug release,and favorable in vitro percutaneous permeability,indicating potential clinical application value.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Purpose To explore the feasibility of artificial intelligence compressed sensing(ACS)technique in ankle joint MRI.Materials and Methods From September to October 2023,32 healthy volunteers who underwent ankle joint scanning in Beijing Friendship Hospital,Capital Medical University were prospectively collected.MRI of the ankle joint based on ACS and parallel imaging(PI)technology was performed on 3.0T MR.The sagittal proton density weighted imaging(PDWI),coronary PDWI,transverse PDWI and sagittal T1WI were acquired,and all data were divided into test group and control group,with ACS to accelerate the multiples of 5(ACS 5.0)in test group,whereas PI speed ratio of 2(PI 2.0)in control group,respectively.The signal intensity of talus,achilles tendon and cartilage were measured,the signal intensity and standard deviation of the long hallux flexor were obtained,and the signal noise ratio(SNR)and contrast to noise ratio(CNR)were calculated via long hallux flexor as background noise.The data of objective and subjective evaluation of the two sequences were statistically analyzed,and the image quality of each sequence was evaluated via the standard reference of PI 2.0.Results SNR and CNR in ACS group were higher than those in PI group,and the anatomical structure of sagittal PDWI sequence between the two groups had statistical significance(t=-2.937,-1.981,-4.058,-3.879,P<0.05).There were significant differences in cartilage SNR and talus CNR in coronal PDWI sequence(t=-3.310,-3.567;P=0.002,P<0.001).In terms of axial PDWI sequence,there were statistically significant differences in talus CNR and cartilage CNR between ACS and PI groups(t=-4.270,-4.382,P<0.05).The subjective evaluation of the image quality scores of the two groups by the two diagnostic imaging doctors showed a strong observer consistency(Kappa=0.977,P=0.009).There was no significant difference in image quality scores between the two groups(Z=-0.248,-0.747,<0.001,-0.071,P>0.05).The total collection time of ACS group and PI group was 337 s and 610 s,respectively.Compared with PI group,the total scanning time of ACS group was shortened by 44.8%.Conclusion ACS based MRI of the ankle joint can not only shorten the scan time,but also ensure and further improve the image quality,with feasibility.
