ObjectiveTo explore the clinical efficacy and safety of Da Chaihutang （DCH） for the treatment of sepsis with Yang syndrome. MethodsA total of 70 patients suffering from sepsis with Yang syndrome were randomly divided into an observation group and a control group， with 35 cases in each group. They both received standard Western medicine treatment. The observation group was additionally given a dose of DCH， which was boiled into 100 mL and taken twice. The control group was additionally given an equal volume and dosage of warm water. The intervention lasted for three days. The 28-day all-cause mortality and the changes in the following indicators before and after intervention were compared between the two groups， including sequential organ failure assessment （SOFA）， acute physiology and chronic health evaluation Ⅱ （APACHE Ⅱ） score，white blood cell （WBC），the percentage of neutrophils （NEU%），C-reactive protein （CRP），procalcitonin （PCT），alanine transaminase （ALT），aspartate transaminase （AST），total bilirubin （TBil），creatinine （Cr），blood urea nitrogen （BUN），acute gastrointestinal injury （AGI） grade，gastrointestinal dysfunction score （GDS），serum intestinal fatty acid-binding protein （iFABP）， citrulline （CR），platelet （PLT），prothrombin time（PT），activated partial thromboplastin time （APTT），fibrinogen （Fib），international normalized ratio （INR），and D-dimer （D-D）. ResultsThere was no significant difference between the two groups regarding 28-day all-cause mortality. After the intervention，SOFA，WBC，PCT，and Cr were significantly decreased， and PLT was significantly increased in the control group （P<0.05）. SOFA，APACHE Ⅱ，NEU%，CRP，PCT，ALT，AST，Cr，BUN，AGI grade，GDS，and serum iFABP and CR were significantly improved in the observation group （P<0.05）. After the intervention，APACHE Ⅱ，PCT，AGI grade，GDS，and serum iFABP in the observation group were significantly lower than those in the control group ，while CR and PLT were higher （P<0.05，P<0.01）. There were significant differences regarding the gap of SOFA，APACHE Ⅱ，AST，TBil，AGI grade，GDS，iFABP，CR， and PLT between the two groups （P<0.05，P<0.01）. There were slight differences regarding PT，APTT，Fib，INR，and D-D between the two groups，which were in the clinical normal range. ConclusionOn the basis of Western medicine， DCH helped to reduce sepsis severity and improved multiple organ dysfunction with high clinical efficacy and safety， but further research on its impact on the prognosis of patients with sepsis is still required.

Deep learning method can be used to automatically analyze electrocardiogram (ECG) data and rapidly implement arrhythmia classification, which provides significant clinical value for the early screening of arrhythmias. How to select arrhythmia features effectively under limited abnormal sample supervision is an urgent issue to address. This paper proposed an arrhythmia classification algorithm based on an adaptive multi-feature fusion network. The algorithm extracted RR interval features from ECG signals, employed one-dimensional convolutional neural network (1D-CNN) to extract time-domain deep features, employed Mel frequency cepstral coefficients (MFCC) and two-dimensional convolutional neural network (2D-CNN) to extract frequency-domain deep features. The features were fused using adaptive weighting strategy for arrhythmia classification. The paper used the arrhythmia database jointly developed by the Massachusetts Institute of Technology and Beth Israel Hospital (MIT-BIH) and evaluated the algorithm under the inter-patient paradigm. Experimental results demonstrated that the proposed algorithm achieved an average precision of 75.2%, an average recall of 70.1% and an average F ₁-score of 71.3%, demonstrating high classification accuracy and being able to provide algorithmic support for arrhythmia classification in wearable devices.

Objective To investigate the diagnostic value of peripheral blood trimethylamine N-oxide(TMAO)combined with neutrophil-to-lymphocyte ratio(NLR)in patients with acute ische-mic stroke(AIS).Methods A total of 100 AIS patients were selected as study group,and 100 non-stroke study objects who underwent physical examinations during the same period were selected as con-trol group.Blood samples were collected from all participants,and plasma TMAO levels were meas-ured using high-performance liquid chromatography-tandem mass spectrometry.TMAO levels and NLR were compared between two groups,and Spearman correlation analysis,multivariate logistic regression analysis,and receiver operating characteristic(ROC)curve were applied to evaluate the diagnostic val-ue of TMAO and NLR in AIS.Results Compared with the control group,the AIS group had signifi-cantly higher TMAO levels and NLR(P＜0.05).Spearman correlation analysis indicated that TMAO and NLR were positively correlated with the occurrence of AIS(P＜0.05).Multivariate Logistic re-gression analysis revealed that age,TMAO,NLR,and hypertension were independent influencing fac-tors for the occurrence of AIS(P＜0.05).The ROC curve showed that the optimal cut-off values for TMAO and NLR in predicting AIS were 3.749 μmol/L and 2.210,respectively.The area under the curve for TMAO combined with NLR in predicting AIS was 0.902,which was higher than that of TMAO or NLR alone(0.808 and 0.801,respectively),and the Youden index for combined prediction was greater.Conclusion Peripheral blood TMAO and NLR are positively correlated with the occurrence of AIS,and the combination of TMAO and NLR can significantly improve the diagnostic efficacy of AIS,providing a basis for early clinical identification of AIS.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To evaluate the clinical outcomes of 514 cases of anterior cruciate ligament(ACL)reconstruction using hamstring tendon autograft and to observe postoperative changes and recovery of the grafts through second-look arthroscopy.Methods This retrospective study collected data from 514 patients who underwent ACL reconstruction with hamstring tendon autograft between May 2015 and June 2018,with a follow-up of at least one year.Knee function recovery and stability were assessed using the Lysholm score,International Knee Documentation Committee(IKDC)score,and Tegner score,along with the pivot shift test and Lachman test.During the second-look arthroscopy,key observations included the synovial coverage,continuity of the reconstructed ligament,and any intra-articular abnormalities.Results The time interval between ACL reconstruction and second-look arthroscopy ranged from 12 to 28 months,with an average of 20 months.Postoperative infection occurred in 2 cases,both of which were successfully treated with arthroscopic debridement and drainage.No other patients experienced infections,graft resorption,or other complications.At the second-look arthroscopy,the Lysholm score significantly improved from(43.56±9.89)preoperative to(92.21±6.12)postoperatively,the difference was statistically significant(P<0.05);The IKDC score increased from(20.32±7.87)to(85.67±10.43),the difference was statistically significant(P<0.05);The Tegner score improved from(4.31±0.82)to(6.61±1.21),the difference was statistically significant(P<0.05).Second-look arthroscopy revealed that the ligament remained intact in 375 patients,with partial tears in 139 patients,ligament tension was maintained in 447 patients,while 67 patients had laxity,the reconstructed ACL graft was deemed to be in good condition in 435 patients and suboptimal in 79 patients,there were significant differences observed in pre-and post-pivot shift test and Lachman test(P<0.05);Among the 514 patients,188(36.58%)successfully returned to sport.Conclusion ACL reconstruction using hamstring tendon autograft effectively restores knee function and stability.In patients followed for more than one years,the grafts show good vascularization and synovial coverage.Emphasis should be placed on systematic postoperative rehabilitation to optimize recovery.

Purpose: Oligometastatic non–small cell lung cancer (NSCLC) patients have been increasingly regarded as a distinct group that could benefit from local treatment to achieve a better clinical outcome. However, current definitions of oligometastasis are solely numerical, which are imprecise because of ignoring the biological heterogeneity caused by genomic characteristics. Our study aimed to profile the molecular alterations of oligometastatic NSCLC and elucidate its potential difference from polymetastasis. Materials and Methods: We performed next-generation sequencing to analyze tumors and paired peripheral blood from 77 oligometastatic and 21 polymetastatic NSCLC patients to reveal their genomic characteristics and assess the genetic heterogeneity. Results: We found ERBB2, ALK, MLL4, PIK3CB, and TOP2A were mutated at a significantly lower frequency in oligometastasis compared with polymetastasis. EGFR and KEAP1 alterations were mutually exclusive in oligometastatic group. More importantly, oligometastasis has a unique significant enrichment of apoptosis signaling pathway. In contrast to polymetastasis, a highly enriched COSMIC signature 4 and a special mutational process, COSMIC signature 14, were observed in the oligometastatic cohort. According to OncoKB database, 74.03% of oligometastatic NSCLC patients harbored at least one actionable alteration. The median tumor mutation burden of oligometastasis was 5.00 mutations/Mb, which was significantly associated with smoking, DNA damage repair genes, TP53 mutation, SMARCA4 mutation, LRP1B mutation, ABL1 mutation. Conclusion Our results shall help redefine oligometastasis beyond simple lesion enumeration that will ultimately improve the selection of patients with real oligometastatic state and optimize personalized cancer therapy for oligometastatic NSCLC.

Polygonum cuspidatum polyketide synthase 1 (PcPKS1) has the catalytic activity of chalcone synthase (CHS) and benzylidene acetone synthase (BAS), which can catalyze the production of polyketides naringenin chalcone and benzylidene acetone, and then catalyze the synthesis of flavonoids or benzylidene acetone. In this study, three amino acid sites (Thr133, Ser134, Ser33) that may affect the function of PcPKS1 were identified by analyzing the sequences of PcPKS1, the BAS from Rheum palmatum and the CHS from Arabidopsis thaliana, as well as the conformation of the catalytic site of the enzyme. Molecular modification of PcPKS1 was carried out by site-directed mutagenesis, and two mutants were successfully obtained. The in vitro enzymatic reactions were carried out, and the differences in activity were detected by high performance liquid chromatography (HPLC). Finally, mutants T133LS134A and S339V with bifunctional activity were obtained. In addition to bifunctional activities of BAS and CHS, the modified PcPKS1 had much higher BAS activity than that of the wild type PcPKS1 under the conditions of pH 7.0 and pH 9.0, respectively. It provides a theoretical basis for future use of PcPKS1 in genetic engineering to regulate the biosynthesis of flavonoids and raspberry ketones.
