Objective: To observe the clinical efficacy and safety of Yiqi Tongluo Decoction in the intervention of early traditional Chinese medicine (TCM) syndromes after ischemic cerebrovascular disease (ICVD) intervention. Methods: From October 2020 to July 2023, a randomized, double-blind, placebo-controlled study was conducted to include 60 patients with qi deficiency, blood stasis, and phlegm obstruction syndrome after ICVD interventional therapy. They were assigned to the Yiqi Tongluo Decoction treatment group (30 cases) and the TCM placebo routine treatment control group (30 cases) according to the randomized block design. Both groups received routine standardized treatment of Western medicine, including dual antiplatelet, lipid regulation, and control of risk factors for cerebrovascular disease. The treatment group was treated with Yiqi Tongluo Decoction based on the control group. The course of treatment was 60 days and follow-up was carried out 2 and 6 months after the operation. The improvement of qi deficiency syndrome, blood stasis syndrome, phlegm syndrome score and TCM syndrome score, modified Rankin score (mRS), Barthel index (BI) score, Fatty acid-binding protein 4 (FABP4) level, incidence of transient ischemic attack (TIA) and ischemic stroke (IS) and incidence of adverse reactions, Head and neck CT angiography (CTA) or digital subtraction angiography (DSA) examination were collected. The clinical efficacy of the patients 2 months after the operation was taken as the main outcome index to preliminarily evaluate the early and long-term efficacy of Yiqi Tongluo Decoction after the ICVD intervention. The early and long-term clinical efficacy and safety of Western medicine standardized treatment combined with TCM Yiqi Tongluo Decoction on patients with qi deficiency, blood stasis and phlegm obstruction syndrome after ICVD intervention were evaluated. The safety of Yiqi Tongluo Decoction in the treatment of patients after ICVD intervention with white blood cell (WBC), C-reactive protein (CRP), fibrinogen (FIB), plasminogen time (PT), recurrence of cerebral ischaemia and restenosis in patients at 2 and 6 months after treatment were evaluated. Results: Compared to the control group, the TCM syndrome scores for qi deficiency, blood stasis and phlegm syndrome in the treatment group reduced significantly, the clinical efficacy improved significantly, the mRS score and FABP4 were reduced, and the BI score was increased. Adverse events such as cerebral ischaemia were fewer in the treatment group than in the control group, but the difference was not statistically significant; levels of CRP, WBC and PT were reduced, and levels of FIB were reduced at 6 months post-treatment, all P<0.01, and images were intuitively compared. The treatment group was superior to the control group. Conclusion Yiqi Tongluo Decoction combined with Western medicine standard treatment can improve the early clinical efficacy of ICVD patients with qi deficiency, blood stasis and phlegm obstruction syndrome after interventional surgery, improve neurological impairment and daily living ability, reduce the state of qi deficiency syndrome, blood stasis syndrome and phlegm syndrome after interventional surgery, and improve the clinical efficacy of TCM. At the same time, it can reduce the level of FABP4, the target of atherosclerosis and restenosis after interventional surgery, reduce the level of inflammation after interventional surgery in patients with ICVD, regulate coagulation function, and reduce the incidence of long-term recurrence of cerebral ischemia after interventional surgery, with good safety.

ObjectiveTo investigate whether Danggui Shaoyaosan （DSS） inhibits oxidative stress and alleviates inflammation via the Ras homolog family member A （RhoA）/Rho-associated coiled-coil containing protein kinase 1 （ROCK）/nuclear factor kappa-B （NF-κB） signaling pathway， thereby delaying the progression of diabetic kidney disease （DKD） and exerting a nephroprotective effect. MethodsEight db/m mice were assigned to the normal group， and forty 8-week-old db/db mice were randomly divided into the model group， DSS low-dose group （8.39 g·kg^-1）， DSS medium-dose group （16.77 g·kg^-1）， DSS high-dose group （33.54 g·kg^-1）， and irbesartan group （0.025 g·kg^-1）， with eight mice in each group. All groups were administered the corresponding treatment by gavage once daily for 12 weeks. The normal and model groups received an equal volume of saline. During administration， changes in body weight， fasting blood glucose （FBG）， and 24 hour urinary protein （24 h UTP） were observed. After 12 consecutive weeks of administration， hematoxylin-eosin （HE） staining and Masson's trichrome staining were used to observe renal histopathological changes in each group. The levels of reactive oxygen species （ROS） in renal tissue were detected using the dihydroethidium （DHE） method. The expression levels of superoxide dismutase （SOD） and malondialdehyde （MDA） in renal tissue were determined. Serum interleukin-1β （IL-1β） and interleukin-6 （IL-6） levels were measured using enzyme-linked immunosorbent assay （ELISA）. The mRNA expression levels of RhoA， ROCK1， and NF-κB p65 in renal tissues were detected by Real-time quantitative polymerase chain reaction （Real-time PCR）. Protein expression levels of fibronectin （FN）， Collagen Ⅳ（Col Ⅳ）， transforming growth factor-β₁ （TGF-β₁）， RhoA， ROCK， and NF-κB p65 in renal tissues were determined by Western blot. ResultsCompared with the normal group， the model group showed significantly increased body weight， FBG， and 24 h UTP levels （P<0.01）， elevated serum IL-1β and IL-6 levels， enlarged glomerular volume， diffuse mesangial expansion， increased mesangial matrix， and marked collagen fiber proliferation in renal tissues. SOD activity was decreased， while MDA， ROS， RhoA， ROCK1， and NF-κB p65 mRNA expression levels were increased （P<0.01）， and the protein expression levels of FN， Col Ⅳ， TGF-β₁， RhoA， ROCK， and NF-κB p65 were also elevated （P<0.01）. Compared with the model group， the DSS low-， medium-， and high-dose groups and the irbesartan group showed reductions in body weight， FBG， and 24 h UTP， decreased serum IL-1β and IL-6 levels， varying degrees of improvement in renal histopathology， increased SOD activity， decreased MDA levels， reduced ROS expression， and significantly downregulated RhoA， ROCK1， and NF-κB p65 mRNA expression （P<0.05， P<0.01）， as well as reduced protein expression levels of FN， Col Ⅳ， TGF-β₁， RhoA， ROCK， and NF-κB p65 （P<0.05， P<0.01）. ConclusionDSS can alleviate oxidative stress and inflammation， reduce extracellular matrix deposition， and delay renal fibrosis progression in db/db mice. Its mechanism may be related to the inhibition of the RhoA/ROCK/NF-κB signaling pathway， thereby exerting a therapeutic effect on DKD.

Existing antidepressant treatments are generally suboptimal for patients with bipolar disorder(BD).Several studies have explored the efficacy of light therapy(LT)in patients with bipolar depression,along with investigating parameters,devices,and safety aspects of LT.This paper provides a review of these aspects.Numerous meta-analyses and randomized controlled trials have indicated that LT could significantly improve depressive symptoms in BD patients,with both low and high intensity white light having this effect,while the antidepressant effect of blue light remains unclear.LT takes effect rapidly,preferably in the morning,with each session lasting between 30 to 60 minutes,but there is no consensus on the most beneficial LT course for BD patients.The most commonly used device for LT is a lightbox.However further exploration is need regarding the safety of LT glasses.When LT devices that meet safety standards is selected,the overall safety of LT will be high and risk of manic or hypomanic switch will be low for BD patients.In conclusion,LT holds promise for patients with bipolar depression,and further research on LT for BD patients should be conducted to explore LT strategies and develop LT prescriptions.

Objectives:To investigate the clinical feasibility of three-dimensional(3D)high-resolution late gadolinium enhancement(LGE)MRI in accessing left atrial myocardial fibrosis in patients with atrial fibrillation(AF). Methods:A total of 34 AF patients referred for hybrid surgical ablation were retrospectively enrolled in this study.3D-LGE-MRI images were acquired by Siemens 3.0 T machine and analyzed by ADAS post-processing software by two experienced radiologists to obtain parameters such as the area and the area percentage of LGE.Regional analysis was performed by one of the two radiologists at ten left atrial segments.The Kappa test was used to assess the agreement for scoring image quality,and the interclass correlation coefficient(ICC)was used to evaluate the interobserver agreement of LGE parameters.The parameters of left atrial morphology,area(and area percentage)of LGE,and location of LGE were compared between patients with persistent AF and paroxysmal AF. Results:Images of all 34 patients were considered to have diagnostic value.The scores of the overall image quality and the clarity of the left atrial wall evaluated by two radiologists were(2.88±0.64)points and(3.26±0.75)points(radiologist 1),(2.97±0.58)points and(3.24±0.70)points(radiologist 2),respectively.The corresponding Kappa values were 0.724 and 0.859.Both the area and the area percentage of LGE showed good consistency among observers,and the ICCs were 0.969 and 0.950,respectively.The difference in the area of LGE and the area percentage of LGE between patients with paroxysmal and persistent atrial fibrillation was similar(both P＞0.05).Compared with patients with paroxysmal AF,patients with persistent AF had a higher Utah stage and more severe myocardial fibrosis in the right inferior pulmonary vein antrum and the left atrial septum(all P＜0.05). Conclusions:3D high-resolution LGE-MRI provides a non-invasive way to visualize and quantify left atrial myocardial fibrosis.The extent of left atrial fibrosis in patients with persistent AF is more severe than that in patients with paroxysmal AF,with a preferential distribution in the right inferior pulmonary vein antrum and the left atrial septum.

Objective To explore the correlation of MPV,NLR,PT,APTT and FIB with early pro-gression of ACI in patients with BAD.Methods A total of 303 ACI patients with BAD admitted in our department of neurology from October 2021 to September 2023 were consecutively recrui-ted,and according to their progression within 7 d of onset,they were divided into progression group(89 cases)and un-progression group(214 cases).The general clinical data,blood routine re-lated indicators(MPV,NLR)and coagulation related indicators(PT,APTT,FIB)were compared between the two groups.Multivariate logistic regression analysis was applied to identify the rela-tionship of above indicators with early progression of ACI in BAD patients.ROC curve was plot-ted to analyze the predictive value of the indictors for disease progression in these patients.Results The progression group had significantly advanced age,larger proportions of diabetes,hyperlipi-demia and stroke history,and increased levels of uric acid,LDL-C,homocysteine,MPV,platelet distribution width,NLR,D-dimer and FIB,and shorter TT,PT and APTT when compared with the un-progressed group(P＜0.05,P＜0.01).Multivariate logistic regression analysis showed that MPV,NLR,PT,APTT,and FIB were all independent influencing factors for early disease pro-gression of ACI in patients with BAD(P＜0.05,P＜0.01).ROC curve indicated that the AUC value of combined MPV,NLR,PT,APTT and FIB in detecting early disease progression was 0.859(95％CI:0.813-0.905).Conclusion Blood routine(MPV,NLR)and coagulation related indicators(PT,APTT,FIB)are closely associated with the early disease progression of ACI in BAD patients,and these indicators are of high value in predicting the early disease progression.

Objective:This study aimed to explore the clinical value of myostatin(MST) and follistatin(FST) as biological biomarkers in evaluating sarcopenia in elderly women.Methods:This was a retrospective cross-sectional study that enrolled 350 females aged 20-89 years who underwent physical examinations in Shanghai Huadong Hospital in 2021. Demographic characteristics, muscle mass, fat mass, bone mineral density, hand grip strength, gait speed, and serum indices of MST and FST were collected.Results:The serum levels of MST did not change significantly with age. However, the serum levels of FST increased with age. In women aged≥60 years, MST was positively correlated with total lean mass and appendicular skeletal muscle index(ASMI; r=0.236, P=0.041; r=0.289, P=0.014), while FST was negatively correlated with ASMI( r=-0.265, P=0.030). In multivariate stepwise regression analysis, after adjusting for age, body mass index, hip bone mineral density, and total fat mass, only FST was independently correlated with ASMI( β=-0.238, P=0.006), while MST was not correlated with ASMI. The receiver operating characteristic curve was plotted using muscle mass reduction as the state variable and serum FST level as the test variable. The area under the curve was 0.753. And when the FST cutoff value was 17.49 ng/mL, the maximum Jordan index was 0.46, with a sensitivity of 77.3% and a specificity of 68.7%. Women aged ≥60 years were divided into three groups based on serum FST levels. Compared to the upper third of the serum FST level group, the low third of the FST level group had a significantly reduced risk of suffering from sarcopenia( OR=0.098, P =0.036). Conclusions:Serum FST lever has a better correlation with muscle mass among elderly women, making it a promising biomarker for evaluating muscle mass.

Objective:To examine the effect of short-term regular aerobic exercise on physical fitness of children with pulmonary with atresia ventricular septal defect after radical biventricular treatment.Methods:This was a prospective self pre-and post-control observation study. The subjects performed regular aerobic exercise for 10 days according to the exercise prescription. Body composition measurement and cardiopulmonary exercise test[lung ventilation function, maximum oxygen uptake(VO 2max), maximum oxygen pulse(O 2/HR max), ventilation oxygen uptake efficiency(OUES), exercise load time], 6 min walking distance(6MWD), sports psychometric test, motor function screening test and fitness test, were collected. The changes of test parameters and scale scoring before and after exercise were analyzed and compared. Results:A total of 7 children with PA/VSD after biventricular surgery were enrolled. The age ranged 8.2-16.2 years old, and there were 2 males and 5 females. VO 2max[(1 196.71±395.31)ml/min vs.(1 297.43±425.73)ml/min, P=0.031], O 2/HRmax[(82.43±7.53)ml/beat vs.(91.57±6.95)ml/beat, P<0.001]increased after exercise. The exercise load time was significantly increased compared with that before intervention[(476.43±35.73)s vs.(531.43±45.76)s, P=0.002]. Resting heart rate before exercise( P=0.013) and peak respiration exchange ratio(PeakRER, P=0.021) were significantly lower. Body composition tests suggest weight, intracellular water, protein and muscle content of lower limb were higher( P<0.05). The motor function score was higher than before( P=0.015); the score of sports fear was lower than before( P=0.009). There was no significant difference in lung capacity and 6-minute walking distance before and after exercise( P>0.05). There were no cardiovascular events during the study period. Conclusion:Short-term regular aerobic exercise for children with PA/VSD after biventricular surgery can improve exercise tolerance, increase lower limb muscle content, improve exercise fear and exercise function, and has good safety and feasibility.

Objective:To explore the role of eosinophil associated ribonuclease A family member 2 (Ear2) in the pathogenesis of lupus and its possible mechanisms involved in renal damage by conditional knockout of myeloid cells in mice.Methods:An Ear2 myeloid conditional knockout mouse model was constructed using CRISP/Cas9 technology, and PCR was applied to identify mice genotype. The experiment was divided into 3 groups: CKO+R848 group, control+R848 group, and control group. R848 (Resiquimod) was used to treat the knockout mice and homozygous control mice to evaluate the occurrence of lupus-like features. Quantitative real-time PCR was performed to detect the expression of Toll-like receptor 7/8 (TLR7/8) and its related inflammatory factors in the kidneys of mice. Flow cytometry (FCM) was used to detect the proportion of patrolling monocytes in the kidneys, and immunofluorescence was used to analyze the spatial distribution of Ear2 and PMOs in renal tissues. In addition, R848 was used to stimulate myeloid cells of conditional knockout (CKO) and control mice in vitro, with changes in the proportion of PMOs detected by flow cytometry. Variance (ANOVA) was used to compare the differences between groups, t-test was used for two-by-two comparisons, and one-way analysis of ANOVA was used for comparisons between multiple groupscant. Results:PCR of myeloid conditioned knockout Ear2 mice showed a genotype of Lyz2 ki/wtEar2 fl/fl and significant down-regulation of Ear2 mRNA levels in bone marrow cells of the knockout mice [(1.03±0.26) vs. (0.22±0.15), t=6.65, P<0.001]. Compared with the control+R848 group, lupus related phenotype presentations of mice was improved and the survival rate tended to increase in the CKO+R848 group (6/10 vs. 7/8, χ2=1.51, P=0.220). The pathological results examination suggested that renal lesions of mice in the CKO+R848 group were also attenuated. The expression level of TLR7 was reduced in the renal tissues of CKO+R848 mice [(1.02±0.09) vs. (0.53±0.04), t=5.13, P=0.003], accompanied by a decrease in PMOs infiltration [(62.00±3.37)% vs. (52.36±0.68)%, t=2.80, P=0.023], and immunofluorescence results showed that Ear2 and PMOs were co-localized in renal tissues. In vitro, R848 stimulation caused an increase in the proportion of PMOs in the control group [(3.99±0.59)% vs. (33.48±1.38)%, t=-33.84, P<0.0001], yet had no effect on CKO mice [(14.33±1.72)% vs. (16.10±1.44)%, t=-1.37, P=0.220]. Conclusion:Conditional knockdown of Ear2 attenuates the development of lupus in mice, especially renal impairments, which is related to the inhibition of TLR7 pathway and reduction of local infiltration of PMOs.

Objective:To investigate the feasibility of a three-dimensional no new U-Net (3D nnU-Net) deep learning (DL) network for the automatic segmentation of colorectal cancer (CRC) based on abdominal CT images.Methods:This was a cross-sectional study. From January 2018 to May 2023, a total of 2180 primary CRC patients, confirmed by pathology at the Guangdong Provincial Hospital of Traditional Chinese Medicine (center 1, n=777), Nanfang Hospital, Southern Medical University (center 2, n=732), and Sun Yat-sen Memorial Hospital (center 3, n=671), were enrolled in this retrospective study. The baseline abdominal CT examination of each patient was conducted using CT equipment from 7 different models across 4 vendors, at the 3 centers, encompassing both the arterial phase (AP) and venous phase (VP). Two radiologists manually delineated the volume of interest to circumscribe the entire tumors in dual-enhanced phase CT images. The CT data of CRC patients from center 1 and center 3 were merged and divided into a training set ( n=1 159) and a validation set ( n=289) using a weighted random method with a ratio of 4∶1. The patients from center 2 were used as an independent external test set ( n=732). The 3D nnU-Net segmentation model was trained and tested. Using manually annotated label data as the benchmark, segmentation performance of the model was evaluated based on different phases and tumor locations. The segmentation coverage rate (SCR), Dice similarity coefficient (DSC), recall (REC), precision (PRE), F1-score, and 95% Hausdorff distance (HD 95) were calculated. The mean manual segmentation time and the mean automatic time were compared using independent samples t-test. Results:In the independent external test set, the performance of the 3D nnU-Net model based on the AP CT images was superior to that based on the VP CT images. On the AP images, the SCR, DSC, REC, PRE, F1-score, and HD 95 were 0.865, 0.714, 0.716, 0.736, 0.714, and 27.228, respectively; on the VP images, they were 0.834, 0.679, 0.710, 0.675, 0.679, and 29.358, respectively. The model achieved the best performance on right-sided colon cancer, with SCR, DSC, REC, PRE, F1-score, and HD95 on the AP CT images at 0.901, 0.775, 0.780, 0.787, 0.775, and 21.793, respectively. Next were left-sided colon cancer and rectal cancer, while the segmentation performance for transverse colon cancer was the worst (SCR, DSC, REC, PRE, F1-score, and HD 95 were 0.731, 0.631, 0.641, 0.630, 0.631 and 38.721, respectively). The automatic segmentation time on a single phase was (1.0±0.3) min, while the manual segmentation time was (17.5±6.0) min ( t=128.24, P<0.001). Conclusions:After training and validating on a dataset from multiple centers with various CT scanner vendors, the 3D nnU-Net DL model demonstrates the capability to automatically segment CRC based on abdominal CT images, while also showcasing commendable robustness and generalization ability.
