ObjectiveTo investigate the effects of Tongxinluo capsules on traditional Chinese medicine （TCM） syndrome elements and major adverse cardiovascular events （MACEs） in patients with chronic coronary syndrome of Qi deficiency and blood stasis type. MethodsA multicenter and prospective cohort study was conducted. The intervention of Tongxinluo Capsules was used as the exposure factor， and the patients were divided into an exposure group （integrated traditional Chinese and western medicine treatment group） and a non-exposure group （western medicine treatment group）. The patients were followed up for one year. The TCM syndrome element scores were assessed by using a syndrome element diagnosis scale on the day of enrollment and in the third， sixth， and twelfth months， and the incidence of MACE within one year was recorded. ResultsA total of 186 patients were included， with 128 patients in the exposure group and 58 patients in the non-exposure group. There was no significant difference in baseline data between the two groups. Compared with those in the pretreatment period for each group， the Qi deficiency and blood stasis syndrome scores in the treatment and follow-up period were significantly improved （P<0.05）. Compared with the non-exposure group， the exposure group exhibited significantly decreased Qi deficiency syndrome scores in the treatment and follow-up period （P<0.01） and significantly reduced blood stasis syndrome scores in the sixth month （P<0.05）. In the remaining follow-up period， there was no statistically significant difference between the two groups. Compared with that of the non-exposure group， during the treatment period （the third month）， the difference in Qi deficiency and blood stasis syndrome scores of the exposure group was statistically significant （P<0.05， P<0.01）. At the end of the follow-up period， patients in the non-exposure group had a MACE probability of 6.90% （4/58）， higher than 3.13% in the exposure group （4/58）. Compared with patients with angina pectoris who used conventional medicine， patients administered with Tongxinluo Capsules had a relative risk（RR） of 0.45 ［95%confidence interval（95%CI） 0.12-1.75， P=0.26］. There was no significant difference in the incidence of MACE within one year between the two groups. ConclusionTongxinluo capsules can improve the degree of Qi deficiency in patients with chronic coronary syndrome in the short term， and the improvement effect of blood stasis syndrome appears in the medium and long term. They can better improve the Qi deficiency syndrome in the long term. Within one year， the incidence of MACE in the exposure group was lower than that in the non-exposure group.

Integrin α _v β ₃ is overexpressed in various tumor cells and angiogenesis. To date, no drug has been proven to target it for therapy. A first-in-human study was designed to investigate the safety, pharmacokinetics, and dosimetry of ¹⁷⁷Lu-AB-3PRGD2, a novel integrin α _v β ₃-targeting radionuclide drug with an albumin-binding motif to optimize the pharmacokinetics. Ten patients (3 men, 7 women; aged 45 ± 16 years) with integrin α _v β ₃-avid tumors were recruited to accept ¹⁷⁷Lu-AB-3PRGD2 injection in a dosage of 1.57 ± 0.08 GBq (42.32 ± 2.11 mCi), followed by serial scans to obtain its dynamic distribution in the body. Safety tests were performed before and every 2 weeks after the treatment for 6-8 weeks. No adverse event over grade 3 was observed. ¹⁷⁷Lu-AB-3PRGD2 was excreted mainly through the urinary system, with intense radioactivity in the kidneys and bladder. Moderate distribution was found in the liver, spleen, and intestines. The estimated blood half-life was 2.85 ± 2.17 h. The whole-body effective dose was 0.251 ± 0.047 mSv/MBq. The absorbed doses were 0.157 ± 0.032 mGy/MBq in red bone marrow and 0.684 ± 0.132 mGy/MBq in kidneys. This first-in-human study of ¹⁷⁷Lu-AB-3PRGD2 treatment indicates its promising potential for targeted radionuclide therapy of integrin α _v β ₃-avid tumors. It merits further studies in more patients with escalating doses and multiple treatment courses.

Objective To investigate the role and possible mechanism of celastrol(Cel)in sodium oxalate(NaOx)-induced acute kidney injury(AKI)and crystal deposition in the kidney tissues in mice.Methods Male C57BL/6 mice(aged 8～12 weeks,weighing 22～24 g)were randomly divided into 3 groups.Saline group(control group,intraperitoneal injection with normal saline and drinking water freely),NaOx group(injured group,intraperitoneal injection of 75 mg/kg NaOx,and drinking water containing 50 μmol/L NaOx),and NaOx+Cel group(treatment group,intraperitoneal injection of 1 mg/kg Cel firstly and then 75 mg/kg NaOx in 24 h later,drinking water containing 50 μmol/L NaOx).All specimens were collected in 24 h after NaOx injection.HK-2 cells were randomly divided into 4 groups:Medium group(no treatment),NaOx group(500 μmol/L NaOx),NaOx+Cel group(400 nmol/L Cel pre-treatment for 2 h followed by 500 μmol/L NaOx treatment),and NaOx+Cel+BA group[8 μmol/L betulinic acid(BA,NF-κB agonist)after the interventions as the NaOx+Cel group].Cells of each group were collected in 24 h after corresponding treatments.Von Koosa and cell adhesion assays were used to observe crystal deposition.HE staining was employed to observe renal histopathology and score the damage.CCK-8 assay was utilized to detect cell viability to obtain the optimal concentrations of NaOx and Cel.Serum urea and creatinine levels were detected.Immunohisotochemical assay was conducted to detect the expression of OPN,CD44,KIM-1,NGAL,p65,IL-1β,BAX,and Caspase-3,and Western blotting was performed for protein levels of OPN,CD44,KIM-1,p65,P-p65 and IL-1β.Results The mice in the NaOx+Cel group showed reduced crystal deposition(P<0.0001),attenuated renal tubular damage(P<0.01),decreased serum urea and creatinine levels(P<0.05),and declined expression levels of the renal adhesion molecules OPN and CD44,the kidney injury molecules KIM-1 and NGAL,the inflammation-associated molecules p65 and IL-1β,and the apoptosis related molecules BAX and Caspase-3 when compared with the NaOx group(P<0.05).In in vitro study,the NaOx+Cel group showed reduced crystal adhesion(P<0.0001),decreased expression of the adhesion molecules OPN and CD44(P<0.05),down-regulation of the inflammatory molecule IL-1β and P-p65/p65 ratio(P<0.05),and down-regulation of the renal injury molecule KIM-1(P<0.05)when compared with the NaOx group.In the NaOx+Cel+BA group,crystal adhesion was significantly increased(P<0.0001),the inflammatory molecule IL-1β and the ratio of P-p65/p65 were increased(P<0.05),and the kidney injury molecule KIM-1 was increased when compared with the NaOx+Cel group(P<0.05).Conclusion Cel may reduce NaOx-induced crystal deposition and AKI by inhibiting NF-κB activation.

Objective It aims to systematically review the concept of hospital digital maturity and its application in the digital transformation of hospitals,analyzes existing digital maturity assessment models internationally,and examine relevant research progress to provide reference and support for the digital transformation of Chinese hospitals.Methods By using the systematic review method,a systematic review was conducted by searching rele-vant literature in both Chinese and English databases,including CNKI,Wanfang Database,PubMed,Medline,and Web of Science.Keywords used for the search included digital maturity,digital capability,health,and hospital.Results Widely used international digital maturity assessment models encompass various dimensions,such as organizational management,digital technology capabilities,healthcare professional digital capabilities,data analytics,and interoperability.Some countries have applied these models in the digital transformation practices of hospitals,while attention to this field remains relatively limited in China.Conclusion Digital maturity assessment is a crucial tool for promoting the digital transformation of hospitals;however,existing evaluation frameworks are not directly appli-cable to China's public hospital system.Future research should focus on developing quantifiable assessment tools tai-lored to the characteristics of Chinese public hospitals,thereby promoting hospital digital transformation and high-quality development.

Objective:To explore the effect of autologous vascular graft bridging of the popliteal artery defect to reconstruct the blood supply of leg on survival of lower extremity.Methods:From May 2021 to May 2024, 10 patients with traumatic popliteal artery injury with defect were treated in the Department of Hand and Foot Surgery, Nanhua Hospital Affiliated to University of South China. A retrospective analysis was conducted on clinical data of the patients. Injury sites were: 6 in left lower extremity and 4 in right lower extremity. Causes of injury were: 4 of traffic accident, 2 of heavy object compression, 2 of electric saw, and 2 of falling from heights. Sixe patients had large vessel injury combined with fracture and (or) knee dislocation, and 4 had simple large vessel injury. Six patients had open vascular injury and 4 had closed vascular injury. There were 6 popliteal artery defect and 4 femoral artery defect, with the defects ranging from 5.0 to 10.0 cm in length. Based on the condition of the arterial defect, autologous great saphenous vein (9 patient) and small saphenous vein (1 patient) were taken and prepared to different forms of vascular bridging graft, such as "single crotch-shape" (6 patient), "double crotch-shape" (3 patient) and "triple crotch-shaped" (1 patient) vascular bridging grafts, to have the defects of popliteal artery reconstructed. Scheduled postoperative follow-up was conducted at outpatient clinic and via telephone interviews. Detailed outcomes including the peripheral blood flow, presence of necrosis or ulcer as well as patient satisfaction were recorded.Results:All of the blood vessel anastomoses in 10 patients were successful and the distal blood supply of the affected legs was restored. All of the affective legs survived. Postoperative follow-ups at 3 to 12 months showed good blood flow in the legs without necrosis nor ulcer as well as a high patient satisfaction.Conclusion:The "crotch-shaped" autologous blood vessel graft can timely and effectively reconstruct defected main artery in popliteal fossa, reduce ischemia time of the affected leg, promote extremity survival and restore its function.

Objective:To evaluate the outcomes of minimally invasive therapy for aortic arch pathology after ascending aortic replacement.Methods:A retrospective analysis was conducted at the Department of Cardiovascular Surgery, West China Hospital of Sichuan University from 2016 to 2024. After multidisciplinary discussion, these included patients were evaluated to be at high risk for traditional open surgery. Various minimally invasive repair techniques were employed, including Ⅳb hybrid technique, physician-modified endograft and novel unibody endograft. The study outcomes were technical success, in-hospital and follow-up mortality, stroke, endoleak, and the patency of the supra-aortic vessels.Results:A total of 40 patients(32 males and 8 females) with a median age of 60 years old were included in this study. The technique success rate was 100%, with no deaths or strokes reported. The patency of the supra-aortic vessels was 100%. 10 patients underwent Type Ⅳb hybrid surgery without any endoleaks occurring. Among the 22 patients who received physician-modified endograft, endoleaks were observed in 2 cases. One of these type Ⅰc endoleaks persisted and underwent reintervention. One patient underwent femoral artery replacement due to vascular injury. For the 8 patients who received novel unibody endograft, one case required reintervention due to persistent type Ⅰc endoleaks.Conclusion:With the development of different endovascular techniques and novel branched endograft, patients with aortic arch pathology who are at high risk for redo open surgery can achieve favorable outcomes with various minimal invasive techniques. However, long-term and large-sample follow-up studies are needed for further evaluation.

Objective:To explore the short-term clinical effects of deep cervical lymph node-venous anastomosis in the treatment of Alzheimer’s disease (AD).Methods:A prospective exploratory study was conducted on the treatment of AD patients using the cervical deep lymph node-venous anastomosis technique in Scar and Wound Treatment Department, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, from September to October 2024. The patients underwent high-frequency ultrasound to locate deep cervical lymph nodes and the external jugular vein. Under general anesthesia, bilateral deep cervical lymph node-venous anastomoses were performed. Indocyanine green (ICG) lymphography was conducted via subcutaneous injection behind the ear to visualize lymph nodes in levels Ⅱ and Ⅲ. After making a skin incision along the posterior margin of the sternocleidomastoid muscle, the external jugular vein, internal jugular veins, and associated lymph nodes were exposed. Adjacent veins were selected for anastomosis of lymph node. Using microsurgical techniques, end-to-side or end-to-end anastomosis was completed for lymph nodes in levels Ⅱ and Ⅲ. Preoperative assessments included the mini-mental state examination (MMSE, a higher score indicates better cognitive function), Alzheimer’s disease assessment scale-cognitive subscale (ADAS-Cog, a higher score indicates greater impairment of cognitive function), Alzheimer’s disease cooperative study scale for activities of daily living (ADCS-ADL, a higher score indicates better ability to perform daily activity), and neuropsychiatric inventory (NPI, a higher score indicates more severe behavioral and emotional symptom). Postoperative follow-up included the same scales to observe changes in cognitive function, activities of daily living, and emotional communication.Results:Four patients (1 male, 3 females, aged 58-79 years) with AD were included. All were diagnosed based on cerebrospinal fluid biomarkers. All patients successfully underwent bilateral deep cervical lymph node-venous anastomoses. On average, 4.3 (2-7 per person) anastomoses were performed per patient. Surgical procedures lasted an average of 6.5 h (5.5-8.5 h) with minimal blood loss (less than 50 ml). Patients resumed normal activity within 6 hours postoperatively and were discharged after an average of 4.1 d (3.5-5.0 d). Postoperative complications included one case each of aspiration pneumonia, lower limb venous thrombosis, and transient delirium, all of whom resolved without long-term effects. Clinical symptoms, including memory decline, mood swings, and anxiety, showed varying degrees of improvement. Patients reported enhanced quality of life, emotional stability, and social engagement, confirming the procedure’s safety and potential cognitive benefits. At one month postoperatively, the MMSE scores of the four patients increased by an average of 0.8 points compared to preoperative levels. Additionally, the two patients who completed the ADAS-Cog assessments showed a decrease in their scores (reduced by 1.0 points and 11.3 points, respectively, compared to preoperative scores), indicating a certain degree of improvement in cognitive function during this period. The ADCS-ADL and NPI scores of four patients varied significantly, without showing any clear pattern.Conclusion:Lymphovenous anastomosis of the deep cervical lymph node-venous anastomosis may provide a new surgical intervention approach for AD, but further large-scale studies and long-term follow-up are needed to validate its safety and effectiveness.
