ObjectiveThis study aims to explore the mechanism and targets of Shenfu Injection in regulating glycolysis to intervene in myocardial fibrosis in chronic heart failure based on the hypoxia-inducible factor-1α （HIF-1α）/ 6-phosphofructo-2-kinase/fructose-2，6-bisphosphatase 3 （PFKFB3） signaling pathway. MethodsA rat model of chronic heart failure was established by subcutaneous injection of isoproterenol （ISO）. After successful modeling， the rats were randomly divided into the Sham group， Model group， Shenfu injection （SFI， 6 mL·kg^-1） group， and inhibitor （3PO， 35 mg·kg^-1） group， according to a random number table， and they were treated for 15 days. Cardiac function was evaluated by echocardiography， and serum N-terminal pro-brain natriuretic peptide （NT-proBNP） levels were detected by enzyme-linked immunosorbent assay （ELISA）. Fasting body weight and heart weight were measured， and the heart index （HI） was calculated. Pathological changes in myocardial tissue were observed by hematoxylin-eosin （HE） and Masson staining， and the fibrosis rate was calculated. Biochemical assays were used to determine serum levels of glucose （GLU）， lactic acid （LA）， and pyruvic acid （PA）. Western blot was used to analyze the expression of proteins related to the HIF-1α/PFKFB3 signaling pathway （HIF-1α and PFKFB3）， glycolysis-related proteins （HK1， HK2， PKM2， and LDHA）， and fibrosis-related proteins ［transforming growth factor （TGF）-β₁， α-smooth muscle actin （α-SMA）， and Collagen type Ⅰ α1 （ColⅠA1）］. Real-time PCR was used to detect the mRNA expression of HIF-1α and PFKFB3 in myocardial tissue. ResultsCompared with the Sham group， the Model group showed significantly decreased left ventricular ejection fraction （LVEF）， left ventricular shortening fraction （LVFS）， interventricular septal thickness （IVSd）， and interventricular septal strain （IVSs） （P<0.05）， while left ventricular internal dimension at end-diastole （LVDd） and end-systole （LVIDs） were increased （P<0.05）. Serum NT-proBNP levels were significantly increased （P<0.01）， and body weight was decreased. Heart weight was increased， and the HIT index was increased （P<0.05）. Myocardial tissue exhibited inflammatory cell infiltration and collagen fiber deposition， and the fibrosis rate was significantly increased （P<0.05）. Serum GLU was decreased （P<0.05）， while LA and PA levels were increased （P<0.05）. Protein expressions of HIF-1α， PFKFB3， HK1， HK2， PKM2， LDHA， TGF-β₁， α-SMA， and ColⅠA1， as well as the mRNA expression of HIF-1α and PFKFB3 were increased （P<0.05）. Compared with the Model group， both the SFI group and 3PO groups showed significant improvements in LVEF， LVFS， IVSd， and IVSs （P<0.05） and decreases in LVDd， LVIDs， and NT-proBNP levels （P<0.05）. Body weight was significantly increased. Heart weight was significantly decreased， and the HIT index was significantly decreased （P<0.05）. Inflammatory cell infiltration， collagen fiber deposition， and the fibrosis rate were significantly decreased （P<0.05）. Serum GLU levels were significantly increased （P<0.05）， while LA and PA levels were decreased （P<0.05）. Expressions of glycolysis-related proteins， fibrosis-related proteins， and HIF-1α/PFKFB3 pathway-related proteins and mRNAs were significantly suppressed （P<0.05）. ConclusionSFI improves cardiac function in chronic heart failure by downregulating the expression of HIF-1α/PFKFB3 signaling pathway-related proteins， regulating glycolysis， and inhibiting myocardial fibrosis.

Chronic heart failure is the terminal stage of various cardiovascular diseases， and cardiomyocyte apoptosis is the turning point of decompensation. Studies have shown that traditional Chinese medicine （TCM） could regulate apoptosis-related signaling pathways and factors and inhibit or up-regulate the expression of apoptosis-related proteins. Thus， TCM can reduce cardiomyocyte apoptosis， protect the myocardial tissue and improve the cardiac function， demonstrating remarkable clinical effects. In recent years， the research on the treatment of chronic heart failure based on the inhibition of cardiomyocyte apoptosis is increasing and becomes the current research hotspot. On the basis of literature review， this paper discovers that TCM regulates apoptosis factors and multiple signaling pathways to inhibit apoptosis and inflammation and delay the progression of chronic heart failure through classical pathways such as the death receptor pathway， the mitochondrial pathway， and the endoplasmic reticulum pathway. At the same time， the studies in this field have the following problems： Repeated studies with shallow， simple， and fragmented contents， treating animal models with TCM prescriptions without syndrome differentiation， treating diseases with drugs at only one concentration which is insufficient to indicate efficacy， and lacking comprehensive， holistic， and systematic studies on the relationships of apoptosis with inflammatory responses， pyroptosis， ferroptosis， and autophagy. In the future， more scientific， reasonable， comprehensive， and feasible experimental schemes should be designed on the basis of comprehensively mastering the research progress in this field， and the communication and cooperation between researchers in different disciplines should be strengthened. The specific pathological mechanism of cardiomyocyte apoptosis in chronic heart failure and the signaling pathways， active components， and action targets of TCM in inhibiting cardiomyocyte apoptosis in chronic heart failure should be elucidated. Such efforts are expected to provide sufficient reference for the clinical treatment of chronic heart failure.

Objective To explore the risk factors for bile leakage after laparoscopic common bile duct exploration(LCBDE)with primary closure.Methods The clinical data of 560 patients with choledocholithiasis who underwent LCBDE with primary closure in Tianjin Hospital of Integrated Traditional Chinese and Western Medicine from September 2021 to September 2023 were retrospectively analyzed,and the patients were divided into the bile leak group and the non-bile leak group according to the occurrence of postoperative bile leakage.The risk factors affecting the occurrence of postoperative bile leakage were analyzed by multivariate analysis.Results A total of 64 cases(11.4% )experienced varying degrees of bile leakage,including 55 cases of grade A bile leakage,7 cases of grade B,and 2 cases of grade C.The thin common bile duct(OR=0.07,P<0.001),history of hypertension(OR=4.56,P<0.001),and high BMI(OR=1.17,P=0.002)were the risk factors for postoperative bile leakage in patients with choledocholithiasis.Conclusion Patients with thin common bile duct,hypertension and obesity are more likely to occur postoperative bile leakage.Patients with choledocholithiasis who have the above high-risk factors should be cautious in choosing LCBDE with primary closure.

A 28-year-old woman presented with a 4-year history of fatigue and sleepiness and was found to have central hypothyroidism and mood disorder. The patient had normal thyroid volume and did not show any other pituitary axis involvement. Over the course of the disease, her symptom improvement matched with the free thyroxine (FT 4) rebound and the adjustment of antipsychotic medication. The patient′s grandmother had central hypothyroidism, and her mother and uncle had lowered or inappropriately normal thyroid stimulating hormone. Hence, genetic involvement was highly suspected, but whole exon sequencing did not reveal a pathogenic variant. Levothyroxine tablets were prescribed to maintain a normal median level of FT 4, and mood disorder medications were adjusted by specialists. Isolated central hypothyroidism is extremely rare, and we report this case aiming to raise awareness of this condition.

Objective:To explore the influence of multidisciplinary treatment (MDT) on clinical staging and diagnosis and treatment strategies for rectal cancer.Methods:A retrospective case series study was conducted. The clinical data of 142 rectal cancer patients who underwent surgical treatment in Shanxi Provincial People's Hospital from March 2021 to December 2021 were retrospectively analyzed. According to whether to implement MDT or not, all patients were divided into MDT group (68 cases) and non-MDT group (74 cases). Relevant clinical data including patients' basic information (gender, age, etc.), TNM staging, whether to receive neoadjuvant radiotherapy and chemotherapy or not, surgical methods, R0 resection rate of both groups were compared. The implementation methods and the effects of MDT for patients were summarized.Results:There were statistically significant differences in the proportion of clinical N staging at initial diagnosis, whether to receive neoadjuvant radiotherapy and chemotherapy or not of both groups (all P < 0.05). The overall agreement rate of clinical T staging at initial diagnosis and pathological T staging was 67.6% (46/68), 50.0% (37/74), respectively in the MDT group and the non-MDT group, and the difference was statistically significant ( χ2 = 4.54, P = 0.033). The overall agreement rate of N staging at initial diagnosis and pathological N staging was 50.0% (34/68), 54.1% (40/74), respectively in the MDT group and the non-MDT group, and the difference was not statistically significant ( χ2 = 0.23, P = 0.629). The treatment rate of neoadjuvant radiotherapy and chemotherapy was 57.4% (39/68) and 4.1% (3/74), respectively in the MDT group and the non-MDT group, and the difference was statistically significant ( χ2 = 48.33, P < 0.001). The R0 resection rate in both the MDT group and non-MDT group was 100.0%, and no tumor tissue was found at the upper, lower, and circumferential margins. Conclusions:MDT could provide more accurate clinical staging and more effective diagnosis and treatment opinions for patients, and provide reliable guidance for the treatment selections.

In recent years,with the increase of social pressure,the incidence of"psycho-cardiological disease"increases.Western medicine mainly uses conventional cardiovascular drugs combined with antidepressant or anxiety drugs.TCM has the characteristics of multi-pathway,multi-target,multi-mechanism,integration and low toxicity.It has unique advantages in the intervention of"psycho-cardiological disease"and has significant clinical efficacy.However,the pathogenesis,clinical diagnosis,syndrome differentiation and treatment of this disease are not the same.This article summarized relevant literature and reviewed the etiology,pathogenesis,experience in syndrome differentiation and treatment,and clinical research of this disease from the perspective of TCM,in order to provide reference for diagnosis of disease,precision treatment and improvement of curative efficacy of"psycho-cardiological disease".

Chronic heart failure is the final stage of various cardiovascular diseases,and mitochondrial energy metabolism disorders have been proved to play an important role in the development of chronic heart failure.TCM believes that heart yin is the material basis of heart yang(qi),and deficiency of heart yang(qi)is the core pathogenesis of chronic heart failure.Based on mitochondrial energy metabolism,this article expounded the scientific connotation of"reinforcing yang from yin"in the treatment of chronic heart failure from the aspects of theoretical connotation,pathogenesis,pathophysiological relationship and modern research.In-depth study at the microscopic level demonstrated that the application of"reinforcing yang from yin"method can effectively improve the reconstruction of heart energy substrate(yin),enhance mitochondrial function,and finally provide energy support(yang),which could offer ideas for theoretical research and clinical prevention and treatment of chronic heart failure.

BackgroundThe existing tools in China for assessing psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint do not sufficiently consider the specialty in psychiatric practice， and the scale items are somewhat cumbersome to use， which together restrict their further promotion and application. Accordingly， there is an urgent need for developing a more scientific assessment tool. ObjectiveTo construct a scale for assessing psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint and to verify its reliability and validity， so as to provide a generic tool for the assessment. MethodsBased on the theoretical framework of the knowledge-attitude-practice model， the preliminary scale was formed through systematic literature review， qualitative interview and Delphi method. From July to December 2021， a stratified sampling was utilized to select 729 psychiatric nurses from tertiary， secondary and primary （including unclassified medical institutions and grassroots hospitals） psychiatric hospitals in Guangdong Province. The formal scale was developed through item analysis， exploratory factor analysis and confirmatory factor analysis. The validity of the scale was evaluated by content validity and structure validity， and the reliability was verified by procedures including Cronbach's α coefficient， test-retest reliability， and split-half reliability. ResultsA total of 12 items of three dimensions （knowledge， attitude， practice） were included in the scale for assessing psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint. The scale-level content validity index （S-CVI） was 0.941， and the item-level content validity index （I-CVI） ranged from 0.812 to 1.000. Exploratory factor analysis extracted three common factors， and the cumulative variance contribution rate was 62.948%. The confirmatory factor yielded adequate fit. Cronbach's α coefficient was found to be 0.887 for the scale， 0.819 for knowledge dimension， 0.842 for attitude dimension， and 0.831 for practice dimension. The split-half reliability and test-retest reliability for the scale were 0.712 and 0.922， respectively. ConclusionThe scale shows satisfactory reliability and validity， which can be used to assess psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint. ［Funded by Guangdong Clinical Teaching Base Teaching Reform Research Project （number， 2021JD119）］

The expression level of NOD-like receptors(NLRP3)inflammasome is significantly elevated in breast cancer tissues,and a high level of NLRP3 inflammasomes is closely associated with breast cancer metastasis.Activation of NLRP3 inflammasome can induce the release of inflammatory factors into the tumor microenvironment(TME).These inflammatory factors,by signaling to cancer cells,reshape the TME to promote tumor growth and invasion,ultimately facilitating the process of epithelial-mesenchymal transition.This equips cancer cells with the ability to establish distant metastases and increase the formation of metastatic lesions.This review addresses the current research status and prospects of NLRP3 inflammasomes in the breast cancer TME and their role in breast cancer metastasis.The goal is to provide new insights for the study of breast cancer metastasis mechanisms and treatment strategies.
