MethodsOne hundred and fourteen patients with heart failure with reduced ejection fraction (HFrEF) and heart failure with mildly reduced ejection fraction (HFmrEF) were randomly allocated into a control group and an observation group. The control group was treated with dapagliflozin tablets, sacubitril-valsartan sodium tablets, metoprolol succinate, and spironolactone, and the observation group was treated with Ershen Zhenwu Decoction on the basis of the therapy in the control group. The course of treatment was 8 weeks in both groups. The 6-min walking distance, New York Heart Association (NYHA) heart function grade, Minnesota Living with Heart Failure Questionnaire (MLHFQ) score, N-terminal pro-B-type natriuretic peptide (NT-proBNP), angiotensin Ⅱ (Ang Ⅱ), left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVIDd), left ventricular end-systolic diameter (LVIDs), interventricular septum thickness at diastole (IVSd), left ventricular end-diastolic posterior wall thickness (LVPWd), left ventricular shortening fraction (FS), miR-423-5p, Smad7, Smad2, Smad3, Smad4, TGF-β1, Ang Ⅱ, type Ⅰ collagen (Col Ⅰ), type Ⅲ collagen (Col Ⅲ), mRNA levels of fibronectin (Fn) and α-smooth muscle actin (α-SMA) in the myocardial tissue were observed before and after treatment in both groups to evaluate the efficacy of cardiac function and drug safety. ResultsAfter treatment, both groups showed declined levels of NT-proBNP, Ang Ⅱ, miR-423-5p, Smad2, Smad3, Smad4, TGF-β1, Col Ⅰ, Col Ⅲ, and mRNA levels of Fn and α-SMA (P0.05), and the levels of the indicators above were lower in the observation group than in the control group (P0.05). After treatment, the Smad7 level increased obviously in both groups (P0.05) and was higher in the observation group than in the control group (P0.05). After treatment, both groups showed decreased MLHFQ scores and increased 6-min walking distance (P0.05), and the observation group had lower MLHFQ score and longer 6-min walking distance than the control group (P0.05). After treatment, the control group showed increased LVEF and FS (P0.05) and the observation group showcased decreased LVIDd and LVIDs and increased LVEF and FS (P0.05). Moreover, the observation group had lower LVIDd and LVIDs (P0.05) and higher LVEF and FS (P0.05) than the control group. The total response rate of cardiac function in the observation group was 90.38% (47/52), which was higher than that (70.59%, 36/51) in the control group (P0.05). No adverse reactions associated with Ershen Zhenwu Decoction were observed during the study period. ConclusionErshen Zhenwu Decoction can improve the cardiac function, exercise tolerance, and quality of life, regulate neuroendocrine factors, and slow down/reverse myocardial remodeling in the patients with HFrEF and HFmrEF (syndrome of heart-kidney Yang deficiency and blood stasis by regulating the miR-423-5p/Smad7/TGF-β1/Smads axis, inhibiting α-SMA and Fn expression, and alleviating myocardial fibrosis.

ObjectiveQi deficiency and phlegm dampness syndrome is a common type of clinical traditional Chinese medicine(TCM) syndrome. However, there is no standard, scientific, and accurate report on the construction of animal models of Qi deficiency and phlegm dampness syndrome. This study aims to construct a mouse model of Qi deficiency and phlegm dampness syndrome by using a multi-factor composite modeling method and to evaluate the model. MethodsTwenty-one C57BL/6 mice were randomly divided into three groups with seven mice in each group, which were the normal group, model group, and Shenling Baizhusan (SLBZ) group. The control group was fed with ordinary diet and kept in a normal environment. The model group and SLBZ group were fed with a high-fat diet in a high-humidity environment. Swimming with heavy weights until exhaustion and gavage with cold water or lard were used to establish the mouse model of Qi deficiency and phlegm dampness syndrome. In order to test the syndrome by prescription, mice in the SLBZ group were treated with SLBZ for 14 days after model construction. The exhaustive swimming time, body weight, serum lipid levels, tongue changes, "Qi deficiency and phlegm dampness" assessment scale score, and cecal index of mice in each group were measured. The feces of each group of mice were sent for metagenomics and metabolome sequencing, and the changes in intestinal flora and metabolites were analyzed. ResultsAfter the modeling of Qi deficiency and phlegm dampness syndrome, the exhaustive swimming time of mice was obviously shortened (P<0.01). The serum total cholesterol, low density lipoprotein cholesterol, and non-high density lipoprotein cholesterol of mice were significantly increased (all P<0.01). The tongue of mice was significantly different from that of the normal group, and the score of the assessment scale was significantly higher than that of the control group (P<0.01). Cecal index decreased significantly (P<0.01). The serum lipid level, tongue image, assessment scale score, and cecal index were reversed in the SLBZ group. Metagenomic and metabolome sequencing results showed that intestinal flora and fecal metabolites were significantly changed in mice with Qi deficiency and phlegm dampness syndrome. Akkermansia_muciniphila, Faecalibaculum_rodentium, Eubacterium_plexicaudatum, Eubacterium sp 14_2, Candida glabrata, Romboutsia_ilealis, Turicibacter sp TS3, and other bacteria had significant changes, and the expressions of intestinal metabolites such as chenodeoxycholic acid, choline, L-phenylalanine betaine, and 2-phenylbutyric acid were significantly changed. Related metabolic pathways such as linoleic acid metabolism, primary bile acid biosynthesis, lysine degradation, arginine biosynthesis, and alpha-linolenic acid metabolism were affected. ConclusionThe Qi deficiency and phlegm dampness model of mice can be constructed by the multi-factor composite modeling method of high-fat diet feeding, high-humidity environment feeding, exhaustive swimming with heavy weight, and intragastric administration with cold water or lard. The blood lipid level, tongue change, score of "Qi deficiency and phlegm dampness assessment scale", cecal index, and changes in related intestinal flora and metabolites of mice can be used as key indicators for model evaluation.

To summarize the distribution characteristics of human papillomavirus(HPV) infection types in patients with cervical squamous intraepithelial lesion(SIL) and cervical cancer(CC), and to explore the impact of HPV vaccination, HPV infection types, and general clinical data on different grades of cervical lesions. Clinical data of women attending the gynecological colposcopy clinic of Shenzhen People's Hospital from January 2020 to December 2023 were retrospectively collected. Patients with HPV genotyping records and histopathologically diagnosed SIL or CC were included and divided into three groups based on pathological results: low-grade squamous intraepithelial lesion(LSIL) group, high-grade squamous intraepithelial lesion(HSIL) group, and CC group. The distribution of high-risk HPV subtypes was analyzed among the three groups, and multivariate Logistic regression was used to identify influencing factors for high-grade cervical lesions. A total of 4162 patients were included, comprising 4057 cervical SIL patients(3317 LSIL and 740 HSIL) and 105 CC patients. The overall mean age was(39.9±11.2) years. The HPV infection rate was 95.1%(3959/4162), and 25.0%(1040/4162) of patients had received HPV vaccination. Among high-risk HPV infections, HPV 52, HPV 16, HPV 58, and HPV 18 were the most common subtypes. HPV 52 had the highest infection rate in the LSIL group(27.6%), while HPV 16 was the most prevalent in the HSIL group(45.3%) and CC group(64.9%). Multivariate Logistic regression analysis showed that HPV vaccination( HPV infection is common in patients with SIL and CC, but the distribution of high-risk HPV subtypes varies among different grades of cervical lesions. It is recommended to strengthen cervical cancer screening and monitoring of key high-risk HPV infections in older and multiparous women in Shenzhen, and to continue promoting HPV vaccination.

BackgroundSocial support can help alleviate depressive symptoms in patients with major depressive disorder (MDD) and improve individual levels of empathy. The higher the level of empathy, the lower the probability of depressive symptoms. At present, the relationship between social support, empathy and depressive symptoms in MDD patients is unclear. ObjectiveTo explore the pathway of empathy in the relationship between social support and depressive symptoms in patients with MDD, so as to provide references for clinical treatment of MDD patients. MethodsA total of 126 patients who visited the outpatient clinic of Tianjin Anding hospital from July 2020 to September 2022 and met the diagnostic criteria for Major Depressive Disorder (MDD) according to the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) were selected as the study subjects. Hamilton Depression Scale-17 item (HAMD-17), Interpersonal Reactivity Index (IRI) and Social Support Rating Scale (SSRS) were used for assessment. Pearson correlation analysis was conducted to examine the correlations among the scale scores. Path analysis was performed using Model 4 of the Process 3.4.1. Bootstrap method was used to test the path effects. ResultsAmong MDD patients, HAMD-17 total score was positively correlated with IRI total score and its subscales of fantasy and personal distress (r=0.225, 0.213, 0.220, P<0.05). HAMD-17 total score was negatively correlated with SSRS total score and its subscales of subjective support and support utilization (r=-0.211, -0.181, -0.208, P<0.05). The score of support utilization subscale of SSRS was positively correlated with IRI total score and its subscale of perspective taking and empathic concern (r=0.257, 0.261, 0.331, P<0.01). Empathy served as a pathway between support utilization and depressive symptoms, with an indirect effect of 0.217 (95% CI: 0.060~0.426), and the effect size was 36.90%. ConclusionEmpathy may serve as a pathway between support utilization and depressive symptoms in patients with MDD.

Recent studies have shown that shorter periods of ejaculatory abstinence may enhance certain sperm parameters, but the molecular mechanisms underlying these improvements are still unclear. This study explored whether reduced abstinence periods could improve semen quality, particularly for use in assisted reproductive technologies (ART). We analyzed semen samples from men with normal sperm counts ( n = 101) and those with low sperm motility or concentration ( n = 53) after 3-7 days of abstinence and then after 1-3 h of abstinence, obtained from the Reproductive & Genetic Hospital of CITIC-Xiangya (Changsha, China). Physiological and biochemical sperm parameters were evaluated, and the dynamics of transfer RNA (tRNA)-derived fragments (tRFs) were analyzed using deep RNA sequencing in five consecutive samples from men with normal sperm counts. Our results revealed significant improvement in sperm motility and a decrease in the DNA fragmentation index after the 1- to 3-h abstinence period. Additionally, we identified 245 differentially expressed tRFs, and the mitogen-activated protein kinase (MAPK) signaling pathway was the most enriched. Further investigations showed significant changes in tRF-Lys-TTT and its target gene mitogen-activated protein kinase kinase 2 ( MAP2K2 ), which indicates a role of tRFs in improving sperm function. These findings provide new insights into how shorter abstinence periods influence sperm quality and suggest that tRFs may serve as biomarkers for male fertility. This research highlights the potential for optimizing ART protocols and improving reproductive outcomes through molecular approaches that target sperm function.

OBJECTIVES:
To investigate the medium- and long-term efficacy of percutaneous mechanical thrombectomy (PMT) combined with stent implantation for treatment of iliac vein stenosis with lower extremity deep venous thrombosis (LEDVT).
METHODS:
Clinical and follow-up data of 125 patients with iliac vein stenosis and LEDVT who underwent PMT and stent implantation at five hospitals in northern Zhejiang province from January 2017 to June 2021 were collected. The thrombus clearance rate, thrombus recurrence rate, patency rate of iliac vein stents and post-thrombotic syndrome (PTS) occurrence rate were documented, and safety indicators such as bleeding, death, pulmonary embolism, stent fracture and displacement were assessed.
RESULTS:
Among 125 patients, for clearance of limb thrombosis, there were 8 cases of grade I (6.4%), 10 cases of grade II (8.0%), and 107 cases of grade III (85.6%). Patients were followed up for a median period of 74 months. According to the Villalta score, the recurrence rates of limb thrombosis at 12, 24 and 36 months were 8.48%, 8.93% and 10.91%; the iliac vein patency rates were 91.52%, 91.07%, and 89.09%; and the incidences of PTS were 5.08%, 5.36% and 6.36%, respectively. There were no major adverse events such as death, massive pulmonary embolism or severe hepatic and renal insufficiency, and no readmission intervention events due to stent fracture or other incidence were found.
CONCLUSIONS
PMT combined with iliac vein stent implantation is effective for patients with iliac vein stenosis complicated by LEDVT with good medium- and long-term efficacy and safety, which is worthy of clinical application.

OBJECTIVE To observe the clinical efficacy of donafenib combined with programmed death-1 (PD-1) inhibitors and vascular intervention therapy in the treatment of unresectable hepatocellular carcinoma (HCC). METHODS This retrospective study included 165 patients with unresectable HCC who were treated at the Fourth and First Affiliated Hospitals of Soochow University between June 2022 and March 2023. Among them, 89 patients received PD-1 inhibitors (tislelizumab or sintilimab, similarly hereinafter) plus vascular intervention (control group) and 76 patients received donafenib in combination with PD-1 inhibitors and vascular intervention (observation group). Short-term efficacy (3 months after treatment), long-term efficacy (2 years after treatment), the levels of liver function indexes [serum alanine amino-transferase (ALT), aspartate transferase (AST), and total bilirubin (TBil)] and tumor biomarkers [alpha fetoprotein (AFP), carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), and des-gamma-carboxy prothrombin (DCP)] before treatment and after 3 months of treatment, as well as the occurrence of adverse drug reaction (ADR) during treatment, were compared between the two groups. In addition, overall response rate (ORR) stratified by PD-1 inhibitor type was analyzed. RESULTS After treatment, the ORR was significantly higher in the observation group than in the control group (P<0.05); although the disease control rate was higher in the observation group compared to the control group, the difference was not statistically significant (P>0.05). The median overall survival of patients in the observation group was 16.9 months [95% confidence interval (CI): 14.2 to 19.1 months], which was significantly longer than that in the control group (12.4 months, 95%CI: 10.1 to 15.3 months) (P<0.05). Subgroup analysis result indicated that therapeutic advantage was consistent across both sintilimab and tislelizumab subgroups, with no significant heterogeneity (P>0.1, I 2<0.001%). Before treatment, there were no significant differences in liver function indexes or tumor marker levels between 2 groups (P>0.05). After treatment, both groups showed significant declines in these indicators compared with baseline (P<0.05), with greater reductions observed in the observation group (P<0.05). There were no statistically significant differences in overall incidence of ADR and grade ≥3 ADRs between the two groups (P>0.05). CONCLUSIONS For patients with unresectable HCC, the combination of donafenib, PD-1 inhibitors and vascular intervention therapy may achieve superior clinical outcomes without increasing the risk of treatment-related ADR.

OBJECTIVE:
To observe the effects of moxibustion at "Xinshu" (BL15) and "Feishu" (BL13) on myocardial transferrin receptor 1 (TfR1), ferroptosis suppressor protein 1 (FSP1), atrial natriuretic peptide (ANP), and typeⅠcollagen myocardial collagen fibers (CollagenⅠ) in rats with chronic heart failure (CHF), and to explore the mechanism of moxibustion for ameliorating myocardial fibrosis and improving cardiac function in CHF.
METHODS:
Fifty SD rats were randomly divided into a normal group (n=10) and a modeling group (n=40). The CHF model was established in the modeling group by ligating the left anterior descending coronary artery. After successful modeling, the rats were randomly divided into a model group (n=9), a moxibustion group (n=8), a rapamycin (RAPA) group (n=9), and a moxibustion+RAPA group (n=9). In the moxibustion group, moxibustion was delivered at bilateral "Feishu"(BL13) and "Xinshu" (BL15), 15 min at each point in each intervention, once daily, for 4 consecutive weeks. In the RAPA group, RAPA solution was administered intraperitoneally at a dose of 1 mg/kg, once daily for 4 consecutive weeks. In the moxibustion+RAPA group, RAPA solution was administered intraperitoneally after moxibustion. Ejection fraction (EF) and left ventricular fractional shortening (FS) were measured after modeling and intervention. After intervention, morphology of cardiac muscle was observed using HE staining and Masson's trichrome staining. Total iron content in myocardial tissue was detected using a colorimetric method. Western blot and qPCR were adopted to detect the protein and mRNA expression of TfR1, FSP1, ANP, and CollagenⅠ in myocardial tissue.
RESULTS:
Compared with the normal group, the EF and FS values decreased (P<0.01); necrosis, edema, degeneration, and arrangement disorder were presented in cardiomyocytes; inflammatory cells were obviously infiltrated, the structure of myocardial fibers was disarranged, the collagen fibers were obviously deposited and fibrosis increased (P<0.01); the total iron content and the protein and mRNA expression of TfR1, ANP, and CollagenⅠ in myocardial tissue were elevated (P<0.01), while the protein and mRNA expression of FSP1 were reduced (P<0.01) in the model group. Compared with the model group, the moxibustion group showed that EF and FS increased (P<0.01); myocardial cell morphology was improved, and myocardial fibrosis was alleviated (P<0.01); the total iron content and the protein and mRNA expression of TfR1, ANP, and CollagenⅠ in myocardial tissue decreased (P<0.01), while the protein and mRNA expression of FSP1 increased (P<0.01, P<0.05). Compared with the model group, the myocardial fibrosis was increased (P<0.05); the total iron content and the protein and mRNA expression of TfR1, ANP, CollagenⅠ in myocardial tissue were increased (P<0.01), while protein and mRNA expression of FSP1 decreased (P<0.01) in the RAPA group. When compared with the RAPA group and the moxibustion + RAPA group, EF and FS were elevated (P<0.01, P<0.05); myocardial cells were improved in morphology, the total iron content and the protein and mRNA expression of TfR1, ANP, and CollagenⅠ in myocardial tissue decreased (P<0.01), while protein and mRNA expression of FSP1 increased (P<0.01) in the moxibustion group. In comparison with the moxibustion + RAPA group, the RAPA group showed the decrease in EF and FS (P<0.01), the worsened myocardial fibrosis (P<0.01), the increase in the total iron content and the protein and mRNA expression of TfR1, ANP, and CollagenⅠ in myocardial tissue (P<0.01), and the decrease in the protein and mRNA expression of FSP1 (P<0.01).
CONCLUSION
Moxibustion at "Feishu" (BL13) and "Xinshu" (BL15) can slow down the process of myocardial fibrosis and improve cardiac function in CHF rats. The mechanism of moxibustion may be related to inhibiting ferroptosis through regulating autophagy.
