ObjectiveTo explore the clinical efficacy and mechanism of Bupi Qingfei prescription （BPQF） in treating stable bronchiectasis in the patients with syndromes of lung-spleen Qi deficiency and phlegm-heat accumulation in the lungs. MethodsA randomized， double-blind， placebo-controlled trial was conducted. Patients were randomized into BPQF and placebo control （PC） groups. On the basis of conventional Western medicine treatment， the BPQF granules and placebo were respectively administered at 10 g each time， twice a day， for a course of 24 weeks. The TCM symptom scores， Quality of Life Questionnaire for Bronchiectasis （QOL-B） scores， lung function indicators， T lymphocyte subsets， level of inflammatory factors in the sputum， level of neutrophil elastase （NE） in the sputum， and occurrence of adverse reactions were observed before and after treatment in the two groups. ResultsA total of 64 patients completed the study， encompassing 32 in the BPQF group and 32 in the PC group. After treatment， the BPQF group showed decreased TCM symptom scores （P<0.01）， increased QOL-B scores （P<0.01）， and declined levels of tumor necrosis factor （TNF）-α and NE （P<0.05， P<0.01）. The PC group showed decreased TCM symptom （except spleen deficiency） scores （P<0.01）， increased the QOL-B health cognition and respiratory symptom domain scores （P<0.05， P<0.01）， and a declined TNF-α level （P<0.01）. Moreover， the BPQF group had lower TCM symptom （except chest tightness） scores （P<0.05， P<0.01）， higher QOL-B （except treatment burden） scores （P<0.05， P<0.01）， and lower levels of interleukin-6 and TNF-α （P<0.05） than the PC group. Neither group showed serious adverse reactions during the treatment process. ConclusionBPQF can ameliorate the clinical symptoms of stable bronchiectasis patients who have lung-spleen Qi deficiency or phlegm-heat accumulation in the lungs by regulating the immune balance and inhibiting airway inflammatory responses.

OBJECTIVE:Repetitive transcranial magnetic stimulation and transcranial direct current stimulation have shown positive effects in improving gross motor function in children with cerebral palsy.A network meta-analysis was performed to analyze the clinical efficacy of repetitive transcranial magnetic stimulation and transcranial direct current stimulation on the improvement of lower limb motor function and gait in children with cerebral palsy.METHODS:Randomized controlled trials(RCT)about repetitive transcranial magnetic stimulation and transcranial direct current stimulation on lower limb motor function and gait in children with cerebral palsy were collected from CNKI,WanFang,VIP,SinoMed,PubMed,Web of Science,Medline.The search time limit was from the inception to October 5,2024.After screening literature,extracting data and evaluating the risk of bias of included studies,Stata 15.0 software was used for network meta-analysis,AND GRADE profiler was used for quality evaluation.RESULTS:A total of 19 studies were included,involving 4 treatment measures:conventional therapy,high-frequency repetitive transcranial magnetic stimulation,low-frequency repetitive transcranial magnetic stimulation and anodic transcranial direct current stimulation.The results of network meta-analysis showed that in terms of improving gross motor function,low-frequency repetitive transcranial magnetic stimulation[mean difference(MD)=9.48,95％confidence interval(CI)(6.61,12.34),P＜0.05]was the most effective.In terms of alleviating spasticity,high-frequency repetitive transcranial magnetic stimulation[MD=-0.63,95％CI(-1.72,0.45),P＜0.05]had the best efficacy.In terms of improving ankle joint range of motion and step speed,transcranial direct current stimulation[MD=2.27,95％CI(1.37,3.17),P＜0.05;MD=0.11,95％CI(0.05,0.17),P＜0.05]was the most effective.CONCLUSION:Existing clinical evidence suggests that low-frequency repetitive transcranial magnetic stimulation has the best therapeutic effect compared with other intervention measures in terms of improving lower limb gross motor function.In terms of reducing spasticity,high-frequency repetitive transcranial magnetic stimulation has a more significant effect.In terms of improving gait,transcranial direct current stimulation has more advantages.

ObjectiveThis study aims to observe the clinical effect of Danggui Liuhuang Tang （DGLHT） on patients with type 2 diabetes mellitus （T2DM） complicated by atherosclerotic cardiovascular disease （ASCVD） at high risk， focus on evaluating the influence of DGLHT on cardiovascular risk indicators such as flow-mediated dilation （FMD）， atherogenic index of plasma （AIP）， and triglyceride-glucose index （TyG）， and explore the regulatory effect of DGLHT on the myeloid differentiation factor 88/nuclear factor-kappa B （MyD88/NF-κB） signaling pathway. MethodsThe clinical study was a single-center， double-blind， and randomized controlled trial. A total of 68 patients with T2DM-ASCVD at high risk for cardiovascular events with Yin deficiency and fire excess syndrome were enrolled and randomly assigned to a treatment group and a control group. The treatment group was given atorvastatin calcium tablets and DGLHT， while the control group was given atorvastatin calcium tablets and placebos. The treatment course was 12 weeks， with a final study completion of 30 patients in the treatment group and 29 in the control group. Changes in cardiovascular risk indicators such as FMD， AIP， TyG， and small dense low-density lipoprotein cholesterol （sdLDL-C） index were compared. Human umbilical vein endothelial cells （HUVECs） were used to establish a vascular endothelial injury and inflammation model. The protective effect of DGLHT on endothelial injury was verified by reverse transcription polymerase chain reaction （Real-time PCR） and Western blot . ResultsAfter 12 weeks of treatment， the AIP in the treatment group significantly decreased compared with that before the treatment （P<0.05）. Compared with the control group， the treatment group showed significant improvements in FMD and TyG （P<0.05）. Additionally， the treatment group demonstrated significant reductions in two-hour postprandial glucose （2 hPG）， glycated albumin （GA）， triglycerides （TG）， apolipoprotein E （Apo E）， and sdLDL-C （P<0.05）. Analysis of traditional Chinese medicine （TCM） syndrome efficacy indicated that in the treatment group， Yin deficiency and fire excess syndromes， including dry throat and mouth （P<0.05）， excessive thirst （P<0.01）， tidal fever and night sweats （P<0.05）， and dry stools （P<0.05）， improved. Compared with the control group， the treatment group showed significant improvements in symptoms of dry throat and mouth （P<0.05） and excessive thirst （P<0.01）. TCM syndrome scores significantly decreased （P<0.01）， and the overall efficacy rate was 56.67%， significantly higher than the 10.34% observed in the control group （P<0.01）. At the cellular level， increasing concentrations of DGLHT led to decreased messenger ribonucleic acid （mRNA） levels of pro-inflammatory cytokines interleukin-6 （IL-6）， tumor necrosis factor-alpha （TNF-α）， and interleukin-1-beta （IL-1β） in lipopolysaccharide （LPS）-stimulated HUVECs （P<0.01）， with significant reductions in the high-concentration group （P<0.01）. DGLHT may inhibit the expressions of MyD88 and phosphorylated （p）-NF-κB p65 proteins in a concentration-dependent manner. ConclusionDGLHT shows significant effects in reducing cardiovascular risks and may exert an anti-inflammatory effect by inhibiting the MyD88/NF-κB signaling pathway. This finding provides a new perspective for the prevention and treatment of cardiovascular diseases in high-risk individuals with T2DM-ASCVD.

Objective:To evaluate the epidemiological characteristics and influencing factors of out-of-hospital sudden cardiac death (SCD) in Hangzhou from 2016 to 2019.Methods:SCD events recorded by Hangzhou Emergency Center from January 1, 2016 to December 31, 2019 were reviewed. Demographic and mortality data were recorded, and the distribution patterns of SCD events in terms of date, time, and population with different characteristics were observed. Time series analysis method and a distributed lag nonlinear model based on quasi-Poisson distribution were used to explore the possible nonlinear association between ambient temperature and SCD incidence.Results:A total of 4 744 out-of-hospital sudden death events were recorded by Hangzhou Emergency Center from January 1, 2016 to December 31, 2019. After excluding non-SCD events and observed events with missing items, 3 743 SCD events were finally included in the study. The survey results showed that the incidence of out-of-hospital SCD in Hangzhou was 96.5 cases per 100 000 person-years. Most of the people who experienced SCD were aged ≥60 years. The incidence in males (2 462 cases, 66%) was significantly higher than that in females (1 281 cases, 34%), and the proportion of events occurring during the day (2 737 cases, 73%) was significantly higher than that at night (1 006 cases, 27%), mainly occurring between 7: 00 and 9: 00. High temperature was associated with an increased risk of SCD. When the average daily temperature was higher than 25.5 ℃, the risk of SCD increased with the further increase of average daily temperature.Conclusions:SCD events mainly occur in the elderly population aged ≥60 years, with a significantly higher incidence in males than in females, and more frequently during the day than at night, mainly between 7: 00 and 9: 00 in the morning. High temperature is closely related to the risk of SCD. It is particularly important to carry out targeted SCD screening and prevention for different populations and implement appropriate prevention strategies for high-risk groups of SCD in high-temperature weather.

Objective:To investigate the correlation between insulin resistance surrogate indicators and early-stage kidney injury in type 2 diabetes mellitus(T2DM).Methods:A total of 918 T2DM patients hospitalized in the Endocrinology Department of Xinhua Hospital from January 2018 to December 2020 were selected, including 313 patients with early-stage kidney injury and 605 without. Differences in insulin resistance surrogate indicators, including triglyceride to high-density lipoprotein cholesterol ratio(TG/HDL-C), triglyceride glucose(TyG) index, and triglyceride glucose-body mass index(TyG-BMI), were compared between the two groups. Factors associated with early-stage kidney injury in T2DM were analyzed, and the impact of TG/HDL-C, TyG index, and TyG-BMI on early-stage kidney injury in T2DM were explored.Results:Compared with T2DM patients without early-stage kidney injury, those with early-stage kidney injury exhibited significantly elevated levels of TG/HDL-C, TyG index, and TyG-BMI( P< 0.001). TG/HDL-C, TyG index, TyG-BMI, age, duration of diabetes, systolic blood pressure, fasting insulin, and HbA 1C were identified as independent risk factors for early-stage kidney injury in T2DM. Compared to the Q1 quartile, the risk in the Q4 quartile was 3.168 times(95% CI 1.993-5.036) for TG/HDL-C, 2.714 times(95% CI 1.710-4.306) for TyG index, and 2.893 times(95% CI 1.820-5.598) for TyG-BMI. Conclusion:Insulin resistance surrogate indicators TG/HDL-C, TyG index, and TyG-BMI are significantly elevated in T2DM patients with early-stage kidney injury, serving as independent risk factors for early-stage renal impairment in T2DM.

Objective:To explore the treatment methods and prognosis of pregnancy-related uterine arteriovenous malformation (UAVM).Methods:A retrospective analysis was conducted on clinical data from 81 patients with UAVM treated at Peking Union Medical College Hospital between March 2019 and March 2024. Clinical manifestations, diagnostic approaches, treatment strategies and prognosis were evaluated.Results:(1) General Information: the age of patients with UAVM was (32.7±4.6) years, with median gravidity and parity of 1 (quartile range: 1, 2) and 0 (0, 1), respectively. Pregnancy termination methods included surgical abortion or curettage in 46 cases (57%, 46/81), medical induction in 17 cases (21%, 17/81), spontaneous abortion in 16 cases (20%, 16/81), vaginal delivery in 1 case (1%, 1/81), and laparoscopic pregnancy tissue removal in 1 case (1%, 1/81). (2) Clinical manifestations: clinical presentations comprised vaginal bleeding in 59 cases [73%, 59/81; median blood loss: 740 ml (440, 1 360 ml)], massive hemorrhage in 9 cases (11%, 9/81, and bleeding combined with lower abdominal pain in 8 cases (10%, 8/81). Ultrasonography revealed intrauterine masses in 65 cases [80%, 65/81; median size: 2.5 cm (1.8, 4.2 cm)]. Elevated serum human chorionic gonadotrophin-β subunit (β-hCG) levels were observed in in 55 cases [85%, 55/65; median: 62.6 U/L (14.9, 300.1 U/L)]. The median time to UAVM diagnosis via ultrasound was 30.0 days (16.0, 52.0 days) after pregnancy termination, with median peak systolic velocity (PSV) and resistance index of 59.8 cm/s (45.0, 79.6 cm/s) and 0.39 (0.36, 0.43), respectively. (3) Treatment and prognosis: treatment modalities included expectant management in 49 cases (36%, 29/81), medication in 13 cases (16%, 13/81), lesion resection in 31 cases (38%, 31/81), and uterine artery angiography in 8 cases (10%, 8/81; 5 confirmed as arteriovenous fistula). The median time of PSV returning to normal after treatment was 53.8 days (36.0, 93.4 days). The average time for β-hCG returning to normal was (60.4±20.4) days. The median return time of menses was 59.0 days (43.0, 75.4 days).Conclusions:Pregnancy-related UAVM carries a high risk of life-threatening hemorrhage, necessitating management in centers equipped for emergency uterine artery embolization. Informed consent must emphasize disease progression risks and prognosis. Treatment stratification should integrate clinical parameters and imaging features.

Objective:To investigate the predictive value of conventional ultrasound，intratumoral and peritumoral radiomics models based on ultrasound images for the efficacy of neoadjuvant therapy in triple negative breast cancer（TNBC），and to construct a combined model.Methods:A total of 122 patients diagnosed with TNBC and admitted to Nanjing Drum Tower Hospital，Affiliated Hospital of Medical School，Nanjing University between April 2020 and December 2023 were retrospectively selected as study subjects. All patients underwent surgical resection after neoadjuvant therapy and were categorized into two groups：50 cases in the pathological complete remission（pCR）group and 72 cases in the non-pCR group according to surgical pathology. A comprehensive array of clinical data，along with conventional ultrasound imaging findings，was systematically collected from patients prior to treatment and at the conclusion of the second cycle of treatment. The region of interest（ROI）was delineated on the baseline two-dimensional gray-scale ultrasound image using 3D Slicer software on the maximum long-axis section of the lesion. The peri-tumor area was obtained by circularly expanding outward by 5 mm，and the imaging histological features were extracted separately. The dataset was then randomly partitioned into a training set and a validation set，with a ratio of 7∶3. The χ2/ t/Mann-Whitney U tests were used for intergroup comparison of general information. Maximum correlation minimum redundancy and least absolute shrinkage and selection operator regression were used to screen the optimal radiomics feature set，respectively. Variables that exhibited statistically significant differences between group comparisons were then employed to construct combined models，incorporating intratumor and peritumor ultrasonographic models. The predictive efficacy，accuracy，and clinical utility of the models were assessed using ROC curves，calibration curves，and decision curve analysis（DCA），respectively. Results:Subsequent between-group comparisons and multifactorial Logistic regression analysis identified blood flow（ OR=0.213，95% CI=0.062-0.735）and change rate of length diameter（ OR=1.091，95% CI=1.013-1.175）as independent risk factors for predicting pCR. A total of seven and eight radiomics features from each of the intratumoral and peritumoral regions were screened for the construction of intratumoral imaging histology score（RS）and peritumoral RS. The Nomogram model was constructed by combining the blood flow，change rate of length diameter，intratumoral RS，and peritumoral RS，and its AUC values in the training and validation sets were 0.884（95% CI=0.815-0.953）and 0.841（95% CI=0.683-0.940），respectively. The calibration curves demonstrated the Nomogram model's exceptional precision，with a C-index of 0.860 and 0.782 for the training and validation sets，respectively. The DCA revealed that the Nomogram model exhibited the optimal net clinical benefit. Conclusions:Conventional ultrasound，intratumoral and peritumoral radiomics models based on ultrasound images have been shown to possess satisfactory predictive value for the efficacy of neoadjuvant therapy in TNBC，thereby facilitating clinical decision-making.

Objective:To investigate the role of dynamic changes in liver stiffness measurement (LSM) in predicting liver-related end-point events (LREs) occurrence in patients with chronic hepatitis B (CHB) with liver fibrosis during long-term antiviral therapy.Methods:Data were collected from CHB patients whose liver biopsy results showed Metavir fibrosis stage F2～F4 or clinically diagnosed cirrhosis. Entecavir antiviral therapy was mainly administered. Follow-up was conducted once every six months. Clinical data such as demographic information, blood routine tests, liver biochemical parameters, HBV virological and serological test results, and LSM were collected. Dynamic changes in LSM were categorized into four types based on LSM levels before treatment (0y) and following two years of antiviral therapy (2y) : (1) LSM 0y < 10 kPa and LSM 2y < 10 kPa, i.e., LSM persisted < 10 kPa; (2) LSM 0y < 10 kPa and LSM 2y ≥ 10 kPa, i.e., LSM increased to ≥ 10 kPa; (3) LSM 0y ≥ 10 kPa and LSM 2y < 10 kPa, i.e., LSM decreased to < 10 kPa; (4) LSM 0y ≥ 10 kPa and LSM 2y ≥ 10 kPa, i.e., LSM persisted ≥ 10 kPa. The predictive role of the dynamic changes of LSM in the occurrence of LREs was analyzed. The Wilcoxon rank-sum test was used for quantitative data. Fisher's exact test was used for categorical data. Multivariate analysis was performed using the Cox proportional hazards regression model. Survival curves were plotted and compared using the Kaplan-Meier. Results:A total of 713 CHB cases with liver fibrosis were included, among whom 512 had cirrhosis. The cumulative incidence of LREs following two years of antiviral therapy was low in patients with LSM 0y < 10 kPa during follow-up (all patients: LSM persisted < 10 kPa 1.6% vs. LSM increased to ≥ 10 kPa 0%; cirrhosis subgroup: LSM persisted < 10 kPa 0% vs. LSM increased to ≥ 10 kPa 0%). The 5-year cumulative incidence of LREs following two years of antiviral treatment was significantly higher in patients with LSM0y ≥ 10 kPa than in those with LSM persisting ≥ 10 kPa and those with LSM decreasing to < 10 kPa during follow-up (all patients: LSM persisted ≥ 10 kPa 12.4% vs. LSM decreased to < 10 kPa 3.6%; cirrhosis subgroup: LSM persisted ≥ 10 kPa 12.6% vs. LSM decreased to < 10 kPa 4.3%). Patients with LSM persisting at ≥ 10 kPa had a significantly increased risk of LREs following two years of antiviral treatment compared with those whose LSM decreased to <10 kPa during follow-up after adjusting for age, gender, baseline body mass index, platelet count, and alanine aminotransferase (all patients, aHR=2.96, 95% CI: 1.41～6.24, P=0.005; cirrhosis subgroup, aHR=2.74, 95% CI:1.26～5.95, P=0.011). Conclusions:LSM<10 kPa before antiviral treatment had a lower risk of liver-related endpoint events following two years of treatment among CHB patients with liver fibrosis. LSM ≥10 kPa before antiviral treatment and LSM persisted ≥10 kPa two years following treatment had a significantly higher occurrence risk of liver-related endpoints than LSM<10 kPa following treatment among CHB patients with liver fibrosis.

Objective:To evaluate the diagnostic value of multimodal Nomogram model combining 18F-FDG PET/CT and ultrasound for triple negative breast cancer (TNBC) . Methods:A total of 61 breast cancer patients admitted at Nanjing Drum Tower Hospital, Affiliated Hospital of Nanjing University Medical School from November 2016 to May 2024 were selected as the study subjects, including 12 cases of TNBC and 49 cases of non-TNBC. 18F-FDG PET/CT metabolic parameters maximum standardized uptake value (SUV max), mean standardized uptake value (SUV mean), minimum standardized uptake value (SUV min), tumor metabolic volume (MTV), and total lesion glycolysis (TLG), as well as the ultrasound parameters long diameter, short diameter, echogenicity, morphology, boundaries, posterior echogenicity, aspect ratio, microcalcifications, blood flow grading and Breast Imaging Reporting and Data System (BI-RADS) grading were compared between patients with and without TNBC. Least absolute shrinkage and selection operator (LASSO) regression was used for feature screening, and binary multivariate logistic regression analysis was conducted on the screened variables to obtain the independent influencing factors for diagnosing TNBC. The independent factors influencing the diagnosis of TNBC were established as Nomogram model and visualized. Receiver operator characteristic (ROC) curve, calibration curve and decision curve analysis (DCA) were used to evaluate the diagnostic efficacy, accuracy and clinical practicability of the model, respectively. Results:There were statistically significant differences in SUV max ( Z=-2.43, P=0.015), SUV mean ( Z=-2.54, P=0.011), morphology ( P=0.004), boundaries ( χ2=4.86, P=0.028), posterior echogenicity ( P=0.027), and blood flow grading ( χ2=4.52, P=0.034) between TNBC and non-TNBC patients. LASSO regression screened out three variables: SUV max, morphology and blood flow grading. Multivariate analysis showed that, SUV max ( OR=1.20, 95% CI: 1.04-1.38, P=0.012), morphology ( OR=0.02, 95% CI: 0.01-0.49, P=0.016), and blood flow grading ( OR=0.06, 95% CI: 0.01-0.74, P=0.028) were the independent influencing factors for diagnosing TNBC. A Nomogram model was established based on the above independent influencing factors. ROC curve showed that, area under the curve (AUC) of SUV max, morphology, blood flow grading, and the Nomogram model were 0.73 (95% CI: 0.60-0.83), 0.66 (95% CI: 0.52-0.77), 0.67 (95% CI: 0.54-0.79), 0.90 (95% CI: 0.79-0.96), respectively, and the diagnostic value of the Nomogram model was higher than that of SUV max ( Z=2.71, P=0.007), morphology ( Z=3.61, P<0.001), and blood flow grading ( Z=2.51, P=0.012) alone. Calibration curve and DCA showed better accuracy and clinical practicability of the Nomogram model. Conclusions:Nomogram model constructed by combining the SUV max of 18F-FDG PET/CT with the morphology and blood flow grading of ultrasound has a promising potential for diagnosing TNBC.
