ObjectiveTo evaluate the clinical efficacy and safety of Tengshen Granules in the treatment of grade 1 hypertension with the syndrome of severe liver heat and hyperactive Yang combined with mild kidney Yin deficiency. MethodsA total of 120 patients with grade 1 hypertension presenting with severe liver heat and hyperactive Yang combined with mild kidney Yin deficiency were enrolled in a randomized， double-blind， placebo-controlled， parallel-group clinical trial. Patients were randomly assigned to the observation group （Tengshen granules） and the control group （placebo）， with 60 cases in each group. On the basis of lifestyle intervention， treatment was administered for 8 weeks followed by a 2-month follow-up. During the study period， traditional Chinese medicine （TCM） syndrome scores， blood pressure， antihypertensive efficacy， blood pressure control rate， and other indicators were recorded and analyzed， and safety was evaluated. ResultsA total of 114 patients completed the trial， including 57 in the control group and 57 in the observation group. Compared with baseline， TCM syndrome scores， systolic blood pressure， and diastolic blood pressure in the observation group were significantly reduced after treatment （P<0.01）. Compared with the control group after treatment， systolic blood pressure in the observation group was lower from week 4 of medication （P<0.05）， and this difference persisted until 2 months after drug discontinuation. For diastolic blood pressure， the observation group was superior to the control group at week 8 （P<0.01）， with no statistically significant differences at other time points. Regarding syndrome improvement， the TCM syndrome scores for severe liver heat and hyperactive Yang combined with mild kidney Yin deficiency showed significant improvement at weeks 6 and 8 of treatment， with the observation group superior to the control group （P<0.05）. During the 1-month follow-up after drug discontinuation， the syndrome scores in the observation group remained lower than those in the control group （P<0.01）. The total effective rate of antihypertensive efficacy in the observation group was higher than that in the control group （χ²=11.389， P<0.05）. In addition， the level of urinary microalbumin in the observation group was lower after treatment than before treatment （P<0.05）. ConclusionTengshen granules demonstrate significant clinical efficacy and good safety in the treatment of grade 1 hypertension with severe liver heat and hyperactive Yang combined with mild kidney Yin deficiency. They can effectively reduce blood pressure and improve related TCM syndrome manifestations.

Objective To explore the predictive value of automated breast ultrasound(ABUS)features combined with Ki-67 in predicting pathological complete response(pCR)after neoadjuvant chemotherapy(NAC)in triple-negative breast cancer(TNBC).Methods A retrospective analysis was conducted on 127 female TNBC patients treated at Xijing Hospital,Air Force Medical University from March 2019 to December 2023.All patients underwent NAC and surgical treatment after ABUS examination.Based on postoperative pathological results,patients were divided into pCR group(n=60)and non-pathological complete response(npCR)group(n=67).Differences in various parameters before NAC were compared between the two groups.LASSO regression was used to identify independent factors influencing pCR after NAC in TNBC patients,and a predictive model was constructed using multivariate logistic regression.The prediction model was internally validated using the Bootstrap method(1000 resamples).The discriminative ability of the model was evaluated using receiver operating characteristic(ROC)curves,and the area under the curves(AUCs)of different prediction models were compared using De-long's test.The accuracy of the model was assessed using calibration curves,and the clinical benefit of the model was evaluated using clinical decision curve analysis(DCA).Results Significant differences were observed between two groups in terms of age,Ki-67,menopausal status,tumor type,posterior echo,coronal plane convergence sign,coronal plane skip sign,and coronal plane white wall sign before NAC(P<0.05).LASSO regression analysis showed that Ki-67,coronal plane convergence sign,and coronal plane white wall sign were independent influencing factors of pCR after NAC in TNBC patients(P<0.05).The AUC of the multivariate logistic regression model based on Ki-67 was 0.733(95%CI 0.646-0.819),the AUC of ABUS model was 0.777(95%CI 0.695-0.858),and the AUC of ABUS combined with Ki-67 model was 0.816(95%CI 0.741-0.890).De-long's test showed that the AUC of the combined model was higher than those of ABUS feature model and Ki-67 model,with statistically significant differences(P<0.05).There was no significant difference in the AUC between ABUS feature model and Ki-67 model(P=0.40).Hosmer-Lemeshow test indicated that the combined model had a good fit(P=0.304).Internal validation results showed that the combined model had a good stability with a consistency index(C-index)of 0.820(95%CI 0.726-0.879).The calibration curve demonstrated good consistency between the predicted and actual probabilities of the combined prediction model,and the DCA curve indicated that the model had favorable clinical benefit.Conclusion The combined ABUS feature and Ki-67 model can be used to predict the probability of pCR after NAC in TNBC patients,providing a reference for the formulation of clinical treatment plans in TNBC patients.

Objective:To explore the effect of remote motor imagery therapy on rehabilitation of patients with severe coronary heart disease(CHD)after percutaneous coronary intervention(PCI).Methods:This randomized con-trolled study enrolled 164 patients with severe CHD undergoing PCI who admitted in the First Affiliated Hospital of Hebei North University between January 2022 and January 2024.Patients were divided into control group(n=82)and intervention group(n=82).Patients in the control group was given conventional home nursing intervention comparing to those in the intervention group receiving additional remote motor imagery therapy.Both groups were intervened for 8 weeks.Indexes of pain,psychological emotion,ability of daily living,motor function and fall were compared between two groups.Results:Compared to those in control group after intervention,patients in interven-tion group had significant lower scores of visual analogue scale(VAS)[(2.03±0.81)points vs.(5.14±0.84)points],the Hospital anxiety and depression scale(HADS)anxiety subscale(HADS-A)[(4.89±0.84)points vs.(9.05±0.78)points],HADS depression subscale(H ADS-D)[(5.31±1.10)points vs.(10.13±0.82)points],HADS total score[(10.20±1.39)points vs.(19.18±1.18)points](P＜0.001 all),and significant higher 6-min walking distance(6MWD)[(439.31±16.51)m vs.(364.94±12.76)m],peak oxygen uptake(VO2 peak)[(20.28±2.40)ml·kg-1·min-1 vs.(17.26±1.35)ml·kg-1·min-1],anaerobic threshold oxygen consumption(VO2AT)[(17.04±1.18)ml·kg-1·min-1 vs.(13.62±1.16)ml·kg-1·min-1],scores of Chinese modified Fall Efficacy Scale(MFES)[(107.28±4.84)points vs.(87.41±4.73)points],ability of daily living(ADL)scale[(78.95±3.92)points vs.(68.00±4.10)points]and Barthel index[(85.83±2.50)points vs.(69.79±3.42)points](P＜0.001 all).We detected significant lower incidence of falling(7.50％vs.21.25％)in the intervention group compared to control group(P=0.013).Conclusion:Remote motor imagery therapy may strengthen motor function and ability of daily living,and relieve pain and negative emotions in patients with severe CHD after PCI.

This study explores whether the current external quality assessment (EQA) level and acceptable bias for basic semen analysis in China are clinically useful. We collected data of semen EQA from Andrology laboratories in the Hunan Province (China) in 2022 and searched for data in the published literature from January 2000 to December 2023 in China. On the basis of these data, we analyzed the coefficients of variation and acceptable biases of different quality control materials for basic semen analysis through robust statistics. We compared these findings with quality specifications based on biological variation from optimal, desirable, and minimum levels of bias to seek a unified and more suitable semen EQA bias evaluation standard for China's national conditions. Different sources of semen quality control material exhibited considerable variation in acceptable biases among laboratories, ranging from 8.2% to 56.9%. A total of 50.0% of the laboratories met the minimum quality specifications for progressive motility (PR), whereas 100.0% and 75.0% of laboratories met only the minimum quality specifications for sperm concentration and total motility (nonprogressive [NP] + PR), respectively. The Z value for sperm concentration and PR+NP was equivalent to the desirable performance specification, whereas the Z value for PR was equivalent only to the minimum performance specification. This study highlights the feasibility of operating external quality assessment schemes for basic semen analysis using quality specifications based on biological variation. These specifications should be unified among external quality control (EQC) centers based on biological variation.

Chronic hepatitis B（CHB）is one of the major challenges in the global public health field. As of 2022，approximately 254 million people worldwide were infected with the hepatitis B virus（HBV）. CHB is one of the main causes of liver cirrhosis and hepatocellular carcinoma（HCC）. Nucleos（t）ide analogs（NAs）and interferon therapy can delay the progression of liver fibrosis by inhibiting viral replication，but they cannot completely avoid the problem of heterogeneous treatment responses. Some patients are in a state of low-level viremia（LLV）during treatment. The persistent LLV state can induce chronic inflammation and the progression of liver fibrosis，ultimately increase the risk of HCC. In patients with poor treatment responses，the continuous active viral replication can induce immune disorders，accelerate the evolution of fibrosis to the decompensated stage of liver cirrhosis，and increase the risk of patient death. This article aims to review the definition，mechanisms，and impact on treatment outcomes of LLV and suboptimal response based on the latest research，provide a basis for optimizing antiviral therapy for CHB.

Objective To explore the expression level,clinical significance of protein disulfide isomerase A3(PDIA3)in endome-trial cancer(EC)tissues,and its effects on Ishikawa cells.Methods Using the TCGA database to analyze the differential expression levels of PDIA3 in different endometrial tissues and explore its relationship with clinical pathological parameters and prognosis of EC pa-tients;Using immunohistochemistry(IHC)to detect the expression level of PDIA3 in clinical endometrial tissue,analyze the clinical pathological parameters,prognosis,and risk factors affecting the prognosis of EC patients with different expression levels;Using Transwell assay,scratch assay,and CCK-8 assay to detect the proliferation,invasion,and migration ability of Ishikawa cells with knockdown PDIA3 expression.Results The expression level of PDIA3 in EC tissue was higher than that in normal endometrial tissue in the TCGA database and clinical specimens(P＜0.05).The expression level of PDIA3 in EC tissue in the G3 grade group was higher than that in the G1 and G2 grade groups in the TCGA database(P＜0.05).The expression level of PDIA3 in EC tissue in FIGO stage Ⅱ-Ⅳ group was higher than that in the stage Ⅰ group,the group with lymph node metastasis was higher than that without lymph node metastasis,and the highly differentiated group was higher than the poorly differentiated group in clinical specimens(P＜0.05);COX regression analysis showed that Federation International of Gynecology and Obstetrics(FIGO)staging and PDIA3 expression level were the independent risk factors of prognosis in EC patients;the survival time of EC patients with high expression of PDIA3 in the TCGA database was shorter than that of the low expression group(P＜0.05),and the survival rate of clinical patients with positive PDIA3 was shorter than that of the neg-ative group(P＜0.05);Transwell assay,scratch assay,and CCK-8 assay showed that the invasion and migration ability of cells in the PDIA3 inhibition group was significantly reduced compared to the normal group and negative control group(P＜0.05).Conclusion PDIA3 is highly expressed in EC tissues and is associated with the malignancy of tumors and poor prognosis of patients;targeted inhibition of PDIA3 expression can reduce the proliferation,invasion,and migration ability of Ishikawa cells.

BACKGROUND: Biomarkers-based prediction of long-term risk of acute coronary syndrome (ACS) is scarce. We aim to develop a risk score integrating clinical routine information (C) and plasma biomarkers (B) for predicting long-term risk of ACS patients. METHODS: We included 2729 ACS patients from the OCEA (Observation of cardiovascular events in ACS patients). The earlier admitted 1910 patients were enrolled as development cohort; and the subsequently admitted 819 subjects were treated as validation cohort. We investigated 10-year risk of cardiovascular (CV) death, myocardial infarction (MI) and all cause death in these patients. Potential variables contributing to risk of clinical events were assessed using Cox regression models and a score was derived using main part of these variables. RESULTS: During 16,110 person-years of follow-up, there were 238 CV death/MI in the development cohort. The 7 most important predictors including in the final model were NT-proBNP, D-dimer, GDF-15, peripheral artery disease (PAD), Fibrinogen, ST-segment elevated MI (STEMI), left ventricular ejection fraction (LVEF), termed as CB-ACS score. C-index of the score for predication of cardiovascular events was 0.79 (95% CI: 0.76-0.82) in development cohort and 0.77 (95% CI: 0.76-0.78) in the validation cohort (5832 person-years of follow-up), which outperformed GRACE 2.0 and ABC-ACS risk score. The CB-ACS score was also well calibrated in development and validation cohort (Greenwood-Nam-D'Agostino: P = 0.70 and P = 0.07, respectively). CONCLUSIONS CB-ACS risk score provides a useful tool for long-term prediction of CV events in patients with ACS. This model outperforms GRACE 2.0 and ABC-ACS ischemic risk score.

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).

Immunotherapy has emerged as a revolutionary approach to treat immune-related diseases. Dendritic cells (DCs) play a pivotal role in orchestrating immune responses, making them an attractive target for immunotherapeutic interventions. Modulation of gene expression in DCs using genome editing techniques, such as the CRISPR-Cas system, is important for regulating DC functions. However, the precise delivery of CRISPR-based therapies to DCs has posed a significant challenge. While lipid nanoparticles (LNPs) have been extensively studied for gene editing in tumor cells, their potential application in DCs has remained relatively unexplored. This study investigates the important role of cholesterol in regulating the efficiency of BAMEA-O16B lipid-assisted nanoparticles (BLANs) as carriers of CRISPR/Cas9 for gene editing in DCs. Remarkably, BLANs with low cholesterol density exhibit exceptional mRNA uptake, improved endosomal escape, and efficient single-guide RNA release capabilities. Administration of BLAN_mCas9/gPD-L1 results in substantial PD-L1 gene knockout in conventional dendritic cells (cDCs), accompanied by heightened cDC1 activation, T cell stimulation, and significant suppression of tumor growth. The study underscores the pivotal role of cholesterol density within LNPs, revealing potent influence on gene editing efficacy within DCs. This strategy holds immense promise for the field of cancer immunotherapy, offering a novel avenue for treating immune-related diseases.
