OBJECTIVE To investigate the effects and mechanisms of Lycium ruthenicum Murr. in improving sleep. METHODS Network pharmacology was employed to identify the active components of L. ruthenicum and their associated disease targets， followed by enrichment analysis. A caffeine‑induced zebrafish model of sleep deprivation was established ， and the zebrafish were treated with L. ruthenicum Murr. extract （LRME） at concentrations of 0.1， 0.2 and 0.4 mg/mL， respectively； 24 h later， behavioral changes of zebrafish and pathological alterations in brain neurons were subsequently observed. The levels of inflammatory factors [interleukin-6 （IL-6）， IL-1β， IL-10， tumor necrosis factor-α （TNF-α）]， oxidative stress markers [superoxide dismutase （SOD）， malondialdehyde （MDA）， glutathione peroxidase （GSH-Px）， catalase （CAT）]， and neurotransmitters [5- hydroxytryptamine （5-HT）， γ-aminobutyric acid （GABA）， glutamic acid （Glu）， dopamine （DA）， and norepinephrine （NE）] were measured. The protein expression levels of protein kinase B1 （AKT1）， phosphorylated AKT1 （p-AKT1）， epidermal growth factor receptor （EGFR）， B-cell lymphoma 2 （Bcl-2）， sarcoma proto-oncogene，non-receptor tyrosine kinase （SRC）， and heat shock protein 90α family class A member 1 （HSP90AA1） in the zebrafish were also determined. RESULTS A total of 12 active components and 176 intersecting disease targets were identified through network pharmacology analysis. Among these， apigenin， naringenin and others were recognized as core active compounds， while AKT1， EGFR and others served as key targets； EGFR tyrosine kinase inhibitor resistance signaling pathway was identified as the critical pathway. The sleep improvement rates in zebrafish of LRME low-， medium-， and high-dose groups were 54.60%， 69.03% and 77.97%， 开发。E-mail：hjp_yft@163.com respectively， while the inhibition ratios of locomotor distance were 0.57， 0.83 and 0.95， respectively. Compared with the model group， the number of resting counts， resting time and resting distance were significantly increased/extended in LRME medium- and high-dose groups （P＜0.05）. Neuronal damage in the brain was alleviated. Additionally， the levels of IL-6， IL-1β， TNF-α， MDA， Glu， DA and NE， as well as the protein expression levels of AKT1， p-AKT1， EGFR， SRC and HSP90AA1， were markedly reduced （P＜0.05）， while the levels of IL-10， SOD， GSH-Px， CAT， 5-HT and GABA， as well as Bcl-2 protein expression， were significantly elevated （P＜0.05）. CONCLUSIONS L. ruthenicum Murr. demonstrates sleep-improving effects， and its specific mechanism may be related to the regulation of inflammatory responses， oxidative stress， neurotransmitter balance， and the EGFR tyrosine kinase inhibitor resistance signaling pathway.

Objective To analyze the clinical efficacy of valve surgeries for infective endocarditis and the affecting factors, and compare the early- and long-term postoperative outcomes of different surgery approaches. Methods The patients with infective endocarditis who underwent valve replacement/valvuloplasty in our hospital from 2010 to 2022 were retrospectively collected. The clinical data of the patients were analyzed. Results A total of 343 patients were enrolled, including 197 patients with mechanical valve replacement, 62 patients with bioprosthetic valve replacement, and 84 patients with valvuloplasty. There were 238 males and 105 females with an average age of (44.2±14.8) years. Single-valve endocarditis was present in 200 (58.3%) patients, and multivalve involvement was present in 143 (41.7%) patients. Sixty (17.5%) patients had suffered thrombosis before surgery, including cerebral embolisms in 32 patients. The mean follow-up time was (60.6±43.8) months. Early mortality within one month after the surgery occurred in 17 (5.0%) patients, while later mortality occurred in 19 (5.5%) patients. Eight (2.3%) patients underwent postoperative dialysis, 13 (3.8%) patients suffered postoperative stroke, 6 patients underwent reoperation, and 3 patients suffered recurrence of infective endocarditis. Smoking (P=0.002), preoperative embolisms (P=0.001), duration of surgery (P=0.001), and postoperative dialysis (P=0.001) were risk factors for early mortality, and left ventricular ejection fraction ≥60% (P=0.022) was protective factor for early mortality. New York Heart Association classification Ⅲ-Ⅳ (P=0.010) and ≥3 valve procedures (P=0.028) were risk factors for late mortality. The rate of composite endpoint events was significantly lower in the valvuloplasty group than that in the valve replacement group. Conclusion For patients with infective endocarditis, smoking and preoperative embolisms are associated with high postoperative mortality, multiple-valve surgery is associated with a poorer prognosis, and valvuloplasty has advantages over valve replacement and should be attempted in the surgical management of patients with infective endocarditis.

This study compared the differences in intestinal absorption characteristics of eleven active components in Rubus multibracteatus(RM) extract(protocatechuic acid, tiliroside, scutellarin, luteoloside, astragalin, epicatechin, catechin, xanthotoxin, p-coumaric acid, caffeic acid, and apigenin-7-O-glucuronide) between normal rats and inflammatory pain model rats using the in-vitro everted intestinal sac model. The RM extract was administered at absorption concentrations of 25.0, 50.0, and 100.0 mg·mL~(-1). The contents of the eleven components in intestinal absorption solution samples were quantified by ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS), and their cumulative absorption(Q) and absorption rate constant(K_a) were calculated to evaluate the absorption characteristics of these components in normal rats and inflammatory pain model rats. The results show that except for catechin, epicatechin, and caffeic acid, the cumulative absorption-time curves of the other eight components(protocatechuic acid, tiliroside, scutellarin, luteoloside, astragalin, xanthotoxin, p-coumaric acid, and apigenin-7-O-glucuronide) exhibit an upward trend without saturation, with correlation coefficients(R~2) all > 0.9, indicating linear absorption. However, the overall absorption of all components is not dose-dependent with increasing concentration, suggesting that their absorption mechanisms are not solely passive diffusion. In both normal and model rats, the jejunum shows the highest absorption for all components except xanthotoxin. The overall absorption of seven components(excluding protocatechuic acid, caffeic acid, apigenin-7-O-glucuronide, and luteoloside) in normal rats is better than that in model rats across all intestinal segments. These findings indicate that the pathological state of inflammatory pain alters the intestinal absorption of RM extract, and its mechanism needs further investigation.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

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 investigate the efficacy of modified anti-mesenteric functional end-to-end anastomosis (Kono-S) on Crohn's disease (CD) .Methods:A retrospective cohort study was conducted. Clinical data of CD patients who underwent modified Kono-S surgery at Jinling Hospital of Medical School of Nanjing University from January 2020 to April 2023 were collected. Primary endpoint was postoperative endoscopic recurrence rate. Secondary endpoints were postoperative complication rate within 30 days, postoperative clinical recurrence rate, and factors influencing endoscopic recurrence. Endoscopic recurrence was defined as Rutgeerts score of i2b or higher at the anastomotic stomas. Clinical recurrence was defined as Crohn's disease activity index (CDAI) >150 points based on the endoscopic recurrence. Patients were divided into recurrence and non-recurrence groups according to the endoscopic recurrence, and univariate analysis and multivariate Logistic regression analysis were used to identify factors of endoscopic recurrence.Results:A total of 75 CD patients [46 men, 29 women; mean age, (38.5 ± 14.1) years; mean CDAI score, (71.8 ± 22.6) points] were included. Sixty patients underwent partial small bowel resection, 6 underwent ileocecal resection, 6 underwent right hemicolectomy, and 3 underwent subtotal colectomy. The operation time was (116 ± 27) minutes, and the time of the modified Kono-S anastomosis construction was (24 ± 4) minutes. Incidence rate of Clavien-Dindo grade Ⅱ or higher complications was 12% (9/75) within 30 days postoperatively, with no intra-abdominal infectious complication and death. During the follow-up period of 15 (6, 23) months, 39 patients underwent endoscopic examination, and the endoscopic recurrence rate was 20.5% (8/39) and clinical recurrence rate was 2.6% (1/39) . Male was identified as the independent risk factor for endoscopic recurrence ( OR = 18.7, 95% CI: 1.7-200.8, P = 0.02) . Conclusion:Modified Kono-S is a safe and convenient treatment for CD with a low risk of anastomotic endoscopic recurrence, however, male patients are more prone to the recurrence.

Objective:The outcomes of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for myelodysplastic syndromes-evolved acute myeloid leukemia (MDS-AML) were explored.Methods:A retrospective review was conducted for 54 patients with MDS-AML treated with allo-HSCT in the Institute of Hematology and Blood Disease Hospital from January 2018 to August 2022. The clinical effects after transplantation were observed, and the related risk factors influencing prognosis were explored.Results:Of the total 54 patients, 26 males, 28 females, and 53 patients achieved hematopoietic reconstruction. After a median follow-up of 597 (15-1 934) days, the 1 year overall survival (OS) rate, disease-free survival (DFS) rate, relapse rate (CIR) and non-relapse mortality (NRM) rate were 75.8%±5.8%, 72.1%±6.1%, 12.7%±4.9%, and 17.1%±5.2%, respectively. The 3 year estimated OS, DFS, CIR, and NRM rates were 57.8%±7.5%, 58.1%±7.2%, 23.2%±6.6%, and 23.7%±6.6%, respectively. The cumulative incidence of acute graft-versus-host disease (aGVHD) was 57.5%±6.9%, and the cumulative incidence of chronic graft-versus-host disease (cGVHD) was 48.4%±7.7%. Hematopoietic cell transplantation comorbidity index (HCT-CI) before transplantation was ≥2, minimal residual disease (MRD) was positive on the day of reconstitution, grade Ⅲ/Ⅳ aGVHD, bacterial or fungal infection and no cGVHD after transplantation were adverse prognostic factors for OS ( P<0.05). COX regression model for multivariate analysis showed that HCT-CI score before transplantation, bone marrow MRD on the day of response, grade Ⅲ or Ⅳ aGVHD, and cGVHD after transplantation were the independent adverse factors for OS ( P=0.001, HR=6.981, 95% CI 2.186-22.300; P=0.010, HR=6.719, 95% CI 1.572-28.711; P=0.026, HR=3.386, 95% CI 1.158-9.901; P=0.006, HR=0.151, 95% CI 0.039-0.581) . Conclusion:For patients with MDS-AML and high risk of relapse, allogeneic transplantation must be considered as soon as possible. The enhanced management of post-transplantation complications and maintenance treatment should be provided whenever possible after transplantation.

Objective In order to shorten the transparency time of clear,unobstructed brain imaging cocktails and computational analysis(CUBIC),improve the transparency efficiency,and explore the possibility of applying hydrophilic tissue transparency technique,this study was conducted to optimize the perfusion of CUBIC technique and compare it with four hydrophilic tissue clearing method in terms of tissue transparency effect,transparency time,area change,volume change and adeno-associated virus(AAV)fluorescence retention.Methods Brain,liver,spleen and kidney of 6 adult Institute of Cancer Research(ICR)mice were subjected to clearing treatment by SeeDB,FRUIT,ScaleS and CUBIC method,respectively.The area and gray value of the samples were measured by Image J 1.8.0,and the volume before and after transparency was measured by drainage method to compare the transparency effect,time and size deformation of each group.Perfusion optimization of the CUBIC was performed by improving the perfusion rate with the optimal perfusion dose,each group of the experimental sample size was 6.Fluorescence preservation by different techniques was evaluated by injecting AAV in the motor cortex of 16 adult mice and taking the cervical spinal segments for transparency treatment after four weeks,and the fluorescence photographs were measured by Image J 1.8.0 to measure the mean fluorescent intensity.Results The optimal perfusion rate and dose of CUBIC was 15 ml/min and 200 ml respectively.For transparency ability and speed,the perfusion CUBIC had the lowest mean gray value and took the shortest time,while CUBIC consumed the longest time,and SeeDB,FRUIT,and ScaleS did not show good transparency ability.In terms of area and volume changes,several techniques showed different degrees of expansion after transparency of tissues or organs.In terms of fluorescence retention,perfusion CUBIC showed the best retention of green fluorescent protein(GFP)fluorescence signal,followed by CUBIC,ScaleS,FRUIT,and SeeDB.Conclusion Perfusion CUBIC technique shows the best tissue transparency,the shortest transparency time,and the most AAV fluorescence retention compared with other techniques.

Objective To evaluate the effects of anterior cruciate ligament (ACL) reconstruction timing on the motor performance and proprioception by clinical evaluation as well as proprioception and motor performance tests on the patients more than 2 years after ACL reconstruction. Methods The patients who underwent ACL reconstruction in the National Institute of Sports Medicine,General Administration of Sport of China from January 2015 to January 2021 and met the inclusion criteria were followed up,and the postoperative data were collected retrospectively.Fifty-six patients who met the inclusion criteria were included in this study and categorized into two groups:early surgery (n=28,who underwent ACL reconstruction ≤3 weeks after injury) and delayed surgery (n=28,who underwent ACL reconstruction >3 weeks after injury).The basic information,clinical evaluation results,proprioception,and motor performance were compared between the two groups. Results The ACL return to sport after injury scale (ACL-RSI) score in the early surgery group was higher than that in the delayed surgery group [(68.68±22.04)scores vs. (55.82±24.87)scores,P=0.045].There was no difference in the range of motion of the knee joint,the positive rate of pivot shift test,or the scores of Tegner,Marx,Lysholm,knee injury and osteoarthritis outcome score (KOOS),and international knee documentation committee (IKDC) between the two groups (all P>0.05).Although there was no significant difference in range of motion of the knee joint between the two groups,the proportion of knee flexion and extension affected in the early surgery group was smaller than that in the delayed surgery group.Neither motor performance (isokinetic strength test,Y-balance test,and single-leg jump test) nor proprioception had difference between the two groups (all P>0.05). Conclusions Early ACL reconstruction outperformed delayed ACL reconstruction in improving the psychological health,emotions,and confidence in returning to sport,accelerating functional recovery of the patients.The timing of ACL reconstruction has no significant effect on the short-term postoperative knee stability,knee function,motor performance,or proprioceptive recovery of the patients.Early ACL reconstruction is recommended for improving the clinical outcomes.

Objective To evaluate the effects of knee flexor and extensor strength on the subjective function and motor performance of knees after anterior cruciate ligament reconstruction. Methods A total of 53 patients who underwent anterior cruciate ligament reconstruction in the National Institute of Sports Medicine,General Administration of Sport of China from June 2015 to June 2021 and met the inclusion criteria were enrolled in this study.The patients were followed up time for at least 2 years.An isometric muscle strength test system was used to measure the strength of bilateral quadriceps and hamstring muscles.The patients were grouped according to whether the limb symmetry index (LSI) of peak torque of quadriceps and hamstring muscle reached 85% at an angular velocity of 60°/s.Specifically,26 patients were classified into group A (LSI≥85%) and 27 patients were classified into group B (LSI<85%).The subjective function and motor performance of knees were compared between the two groups. Results In terms of subjective function of knees,the international knee documentation committee (IKDC) score (88.76±9.93 vs. 81.08±12.57,P=0.017) and knee injury and osteoarthritis outcome score (KOOS) (86.27±8.96 vs. 80.22±11.31,P=0.036) were different between groups A and B.There was no significant difference in Lysholm score [95.0 (79.8,100.00) vs. 86.00 (66.00,100.00),P=0.238],ACL return to sports after injury scale score (66.08±22.25 vs. 61.12±23.53,P=0.434),Marx score [6.00 (4.75,7.00) vs. 6.00 (4.00,7.00),P=0.805] or Tegner activity score [8.00 (4.00,12.00) vs. 4.00 (2.00,12.00),P=0.566] between the two groups.In terms of motor performance,the single-leg triple hop LSI (0.92±0.13 vs. 0.81±0.18,P=0.016) and single-leg crossover hop LSI (0.96±0.12 vs. 0.84±0.22,P=0.021) showed significant differences between groups A and B,while there was no significant difference in single-leg hop LSI (0.90±0.18 vs. 0.79±0.25,P=0.116) between the two groups.In addition,there was no statistical significance in proprioception [30°:8.83±4.66 vs. 10.73±4.63,P=0.143;45°:6.94±3.82 vs. 7.66±3.93,P=0.504;60°:4.10 (3.20,4.72) vs. 3.90 (2.30,5.20),P=0.493] or Y-balance test results [anterior LSI:0.98 (0.84,1.02) vs. 0.94 (0.86,0.98),P=0.328;posterolateral LSI:1.00±0.08 vs. 0.97±0.07,P=0.249;posteromedial LSI:1.00 (0.97,1.03) vs. 0.96 (0.93,1.03),P=0.179] between groups A and B. Conclusion The patients with good symmetry of quadriceps and hamstring muscle strength after anterior cruciate ligament reconstruction had better subjective function and movement performance of knees than the patients with poor symmetry,which was mainly reflected in the IKDC score,KOOS,single-leg triple hop,and single-leg crossover hop.
