Objective:To explore the efficacy of indocyanine green angiography (ICGA) in preventing flap perfusion disorders after liposuction combined with abdominoplasty.Methods:A retrospective analysis was conducted on the clinical data of patients who underwent liposuction combined with abdominoplasty and used ICGA to evaluate flap perfusion in the Department of Plastic Surgery, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology from March 2022 to March 2024. After the incision was sutured, 2 ml of indocyanine green solution (2.5 mg/ml) was intravenously injected, and a fluorescence angiography imaging system was used to observe perfusion in the distal flap and the suture site. Lack of fluorescence within 3 minutes after injection indicated local hypoperfusion. Flap perfusion was observed on the 1st, 2nd, and 3rd days after surgery, and compared with intraoperative ICGA results.Results:A total of 52 female patients were included, aged 29-55 years, with an average age of 33.8 years. The size of the flap excised during surgery ranged from 12 cm×29 cm to 19 cm×42 cm, and the liposuction volume was 300-1 400 ml. Among the 52 patients, 3 cases showed blood supply disorders in the central area of the distal flap during intraoperative ICGA examination. Timely release was performed, but there was still obvious tension in the distal flap. All 3 cases developed distal flap hypoperfusion after surgery, with sizes ranging from 3 cm×3 cm to 7 cm×5 cm. The range was basically consistent with the area shown by ICGA. After dressing changes, the flaps healed well. During a 12-month follow-up, the three patients reported no wound discomfort or dissatisfaction with the appearance. The ICGA images of the remaining 49 patients were good during the operation, and the blood supply of the flaps was good after the operation. After a 12-month follow-up, the abdominal appearance of 52 patients was satisfactory.Conclusion:ICGA for evaluating flap blood supply in liposuction combined with abdominoplasty has the advantages of simple operation, fast imaging speed, and high diagnostic accuracy. It has application prospects in preventing flap necrosis after liposuction combined with abdominoplasty.

Advancements in artificial intelligence(AI)and emerging technologies are rapidly expanding the exploration of chemical space,facilitating innovative drug discovery.However,the transformation of novel compounds into safe and effective drugs remains a lengthy,high-risk,and costly process.Comprehensive early-stage evaluation is essential for reducing costs and improving the success rate of drug development.Despite this need,no comprehensive tool currently supports systematic evaluation and efficient screening.Here,we present druglikeFilter,a deep learning-based framework designed to assess drug-likeness across four critical dimensions:1)physicochemical rule evaluated by systematic determination,2)toxicity alert investigated from multiple perspectives,3)binding affinity measured by dual-path analysis,and 4)compound synthesizability assessed by retro-route prediction.By enabling automated,multidimensional filtering of compound libraries,druglikeFilter not only streamlines the drug development process but also plays a crucial role in advancing research efforts towards viable drug candidates,which can be freely accessed at https://idrblab.org/drugfilter/.

Objective:To compare the clinical manifestations,laboratory results,and imaging features between pyogenic spondylitis(PS) and tuberculous spondylitis(TS).Methods:This was a cross-sectional study. A total of 88 patients with infectious diseases of spine(IDS) admitted to Shanghai Sixth People′s Hospital from January 2021 to December 2023 were analyzed,including 61 PS cases(PS group) and 27 TS cases(TS group). The clinical manifestations,laboratory results,and imaging features were compared between two groups. The factors associated with PS were analyzed by multivariate logistic regression. The diagnostic efficacy for pathogen identification was compared between metagenomics next-generation sequencing(mNGS) and bacterial culture methods in PS and TS patients.Results:Compared with the TS group,the PS group had a higher age-adjusted Charlson comorbidity index(aCCI)[3.0(1.5,4.0) points vs. 2.0(1.0,3.0) points, Z=-2.189, P=0.029],shorter onset time of disease[1.0(0.8,3.0) months vs. 6.0(2.0,12.0) months,Z=-4.353, P<0.001],and higher median blood leukocyte counts and serum ferritin(SF) level(7.2×10 9/L vs. 6.3×10 9/L, Z=-2.652, P=0.008; 571.3 ng/ml vs. 266.0 ng/ml, Z=-4.773, P<0.001). The proportions of lumbar spine involvement,non-collapsed involved vertebrae,and bone bridges formed were all higher in the PS group compared to the TS group[68.8%(99/144) vs. 41.4%(29/70), χ2=14.628, P<0.001; 68.9%(42/61) vs. 18.5%(5/27), χ2=19.055, P<0.001; 41.0%(25/61) vs. 7.4%(2/27), χ2=9.921, P=0.002]. The proportions of thoracic spine involvement,severe vertebral collapse,severe narrowing of the involved intervertebral space,sequestrum,and paravertebral soft tissue calcification were all higher in the TS group compared to the PS group[52.9%(37/70) vs. 18.1%(26/144), χ2=27.463, P<0.001; 55.6%(15/27) vs. 13.1%(8/61), χ2=17.462, P<0.001; 74.1%(20/27) vs. 37.7%(23/61), χ2=9.907, P=0.002; 74.1%(20/27) vs. 18.0%(11/61), χ2=25.761, P<0.001; 51.9%(14/27) vs. 6.6%(4/61), χ2=23.599, P<0.001]. Multivariate logistic regression analysis indicated that a symptom duration<5.5 months( OR=30.644,95% CI: 2.022-464.529, P<0.05) and a leukocyte count>7.35×10 9/L( OR=48.653,95% CI: 2.045-1 157.721, P<0.05) indicated a higher likelihood of PS; while the vertebral collapse indicated a higher likelihood of TS( OR=0.025,95% CI: 0.001-0.638, P<0.05). The most common pathogen in the PS group was Staphylococcus aureus(31 cases,50.8%),followed by Streptococcus species(10 cases,16.4%). The positive rates of mNGS testing in the PS and TS groups were 84.1%(37/44) and 12/13,respectively,which were higher than those of conventional bacterial culture[77.8%(42/54)] and Mycobacteriumtuberculosis culture(2/11). Conclusions:Compared with the TS patients,the PS patients have shorter onset time,higher aCCI scores,higher blood leukocyte counts and SF levels,less vertebral collapse and intervertebral space narrowing,and more bone bridge formation. The TS patients have more dead bones and calcifications. The mNGS has a higher diagnostic efficacy than bacterial cultures for PS and TS.

Objective:To analyze the safety and efficacy of multi-vessel minimally invasive cardiac surgery-coronary artery bypass graft(MICS-CABG) through perioperative angiography results and complications.Methods:Clinical data of 1 073 patients who underwent multi-vessel MICS-CABG surgery at Peking University Third Hospital from December 2015 to June 2024 were collected using an ambispective cohort study. Among them, 745 were males(69.4%), with a median age of 65 years(58, 71), and a median ejection fraction of 0.66(0.56, 0.71). Double-vessel or triple-vessel lesions accounted for 932 cases(86.9%), while left main lesions were present in 449 cases(41.8%). The primary outcome was the evaluation of graft patency based on perioperative angiography or coronary artery computed tomography angiography results, while major cardiovascular adverse events during the perioperative period, surgical complications, and other surgical information were secondary outcomes. The clinical efficacy of multi-vessel MICS-CABG was evaluated.Results:In this study, the median number of grafts was 3, and complete revascularization was performed in 1 006 cases(93.8%); total arterial revascularization was performed in 308 cases(28.6%). Perioperative mortality was 11 cases(1.0%), and the main adverse cardiovascular and cerebrovascular events(MACCE) was 50 cases(4.8%). Three cases(0.3%) had poor wound healing, and 79 patients(7.4%) required transfusion. Postoperative coronary angiography was performed in 907 patients(84.5%) and coronary CTA was performed in 52 patients(4.8%), for an overall review rate of 89.4%(959/1073). The overall patency rate of the bridge vessel was 96.9%, and the patency rate of the left internal mammary artery was 98.2%.Conclusion:Multi-vessel MICS-CABG demonstrates excellent perioperative safety and is capable of achieving complete revascularization for the 3 regions of the heart. The quality of the anastomosis and the postoperative patency rate of the grafts is satisfactory.

ObjectiveTo explore the influence of electroacupuncture combined with point bloodletting and cupping for facial nerve function recovery in acute stage of idiopathic facial palsy （IFP）. MethodsEighty patients with IFP in the acute stage were randomly divided into 40 cases each in the treatment group and the control group. In the control group， oral prednisone acetate tablets were administered during the acute stage when the disease duration was less than 10 days； and electroacupuncture and flash cupping were provided during the recovery stage when the disease duration was more than 10 days， five times a week. For treatment group in acute stage， the stellate ganglion， vagus nerve stimulation point in the auricular cavity， Yifeng （TE 17） and Tinghui （GB 2） were needled on the affected side on the basis of the treatment of control group， with Yifeng and Tinghui connecting to electroacupuncture apparatus， once a day； point bloodletting and then cupping in Yifeng 2 times a week； in recovery stage， the treatment was the same as that of the control group. Both groups were treated until the 45th day from onset. The primary outcome was the Toronto facial grading system （SFGS）， and the secondary outcomes included house-brackmann （H-B） grade， facial disability index （FDI） score， and number of H-B grade-Ⅰ cases. Adverse events were recorded in both groups. ResultsThe SFGS scores of the patients in both groups were higher on the 10th， 30th and 45th days after onset of disease compared with those before the treatment （P＜0.05）； the H-B grade was lower on the 30th and 45th days after the onset of the disease compared with those before the treatment （P＜0.05）； and the facial disability index physical function （FDIP） and facial disability index social function （FDIS） scores were higher on the 30th and 45th days after onset of disease （P＜0.05）. SFGS scores of patients in the treatment group were significantly higher than those of the control group on the 30th and 45th days after onset （P＜0.05）； H-B grade was significantly lower than that of the control group on the 30th and 45th days after onset （P＜0.05）； and FDIP scores on the 45th day after onset， and FDIS scores on the 30th and 45th days after onset were significantly higher than those of the control group （P＜0.05）. At the end of treatment， 77.50% （31 cases） achieved H-B grade-Ⅰ in the treatment group， which was more than 55.00% （22 cases） in the control group （P＜0.05）. No adverse events occurred in either group. ConclusionElectroacupuncture combined with point bloodletting and cupping for IFP in acute stage can improve the recovery degree of facial nerve function， improve effectiveness， and show a high degree of safety.

In the treatment of diabetic gastroparesis(DGP),traditional Chinese medicine has conventionally focused on therapies such as ascending clear and descending turbid,pungent-opening and bitter-descending methods,aiming to regulate the ascending and descending of the spleen and stomach's Qi mechanism and to restore the middle-jiao's transformation as the ultimate goal.By explo-ring the physiological relationship between gallbladder and spleen-stomach and its pathological relationship with DGP,this article sug-gests that the gallbladder also participates in the regulation of blood sugar and digestive activities in the body,which is closely related to the onset of the disease.As the Shao Yang pivot,the gallbladder stores essential fluid,harbors ministerial fire,primarily governs the upward movement and dispersion,and is responsible for decision-making and emotions.The normal flow of Qi,blood,and body flu-ids,as well as the functional activities of the channels and collateral vessels,are closely associated with the gallbladder.When the gallbladder's function becomes abnormal,the body may also exhibit imbalances in the intestinal microbiota,disarray of gastrointestinal hormones,delayed gastric emptying,and elevated blood sugar levels,which aligns with the modern medical understanding of the onset of gastroparesis diabeticorum.Therefore,this article proposes the treatment principle of"venting the wood constraint"and the treatment of DGP according to symptoms,offering a reference for clinical treatment.
