Chronic heart failure （CHF） is a complex clinical syndrome that the cardiac output is not enough to meet the metabolic needs of the body， or depends on the increase of filling pressure to compensate. Its high morbidity and mortality pose a serious threat to human health， necessitating attention and active intervention. At present， western medicine treatment of CHF is mainly based on diuretics， intravenous vasodilators， intravenous positive inotropic drugs， etc.， which， however， have problems such as long medication cycles， serious side effects， and limited applicable population. Recent studies have shown that traditional Chinese medicine can act in a multi-pathway， multi-component， and multi-target manner， showing unique advantages in the prevention and treatment of CHF. Buyang Huanwutang has the effects of tonifying Qi， activating blood， and dredging collaterals. Clinical and mechanism studies have confirmed that this prescription is effective in treating CHF and its syndromes. The clinical studies can be classified into two categories. Studies of the first category use simple modern medical diagnostic criteria as the inclusion criteria for CHF patients， which can improve the scientificity and objectivity. Studies of the second category uses modern medicine combined with traditional Chinese medicine disease diagnostic criteria for the screening of CHF patients， which helps to improve the accuracy of efficacy evaluation. However， there are problems such as the lack of unified research standards and the insufficiency of mechanism research. In addition， the available studies remain to be classified or summarized. This study systematically sorted out the clinical and mechanism studies of Buyang Huanwutang in the treatment of CHF in recent years to review the research status. In clinical treatment， Buyang Huanwutang can be used alone， or modified， or combined with other prescriptions or Western medicine. The mechanism studies predict that Buyang Huanwutang can ameliorate CHF by regulating the calcium balance， protecting the mitochondrial structure and function， and regulating intestinal flora. This review aims to provide a theoretical basis and practical guidance for the clinical application and optimization and subsequent in-depth study of Buyang Huanwutang in the treatment of CHF.

Chronic subdural hematoma (CSDH) is a collection of blood, blood clots and their degradation products, encapsulated by membrane and located within dural border cell layer. Pathophysiological processes such as inflammatory responses within hematoma cavity, coagulation abnormalities, and abnormalities in neovascularization play significant roles in CSDH development. High mobility group box 1 (HMGB1) can mediate processes such as inflammation, angiogenesis, and hemostasis, while thrombomodulin (TM) can bind with HMGB1 and rely on thrombin to degrade HMGB1. Current research has confirmed that the expressions of TM, HMGB1, and their downstream related factors are abnormally increased in the hematoma fluid of CSDH; however, the role of TM-thrombin-HMGB1 pathway in CSDH development is not fully clear. This article reviews the role of TM-thrombin-HMGB1 pathway in CSDH development, aiming to provide some references for pathogenesis and new therapeutic targets of CSDH.

As a new clinical trial mode,decentralized & digitalized clinical trial(DCT)is based on digital health equipment and uses internet and artificial intelligence technologies to complete the screening,registration,randomization,intervention,evaluation and follow-up of subjects,which is helpful to improve efficiency and reduce trial costs.The DCT mode has been applied to evaluate the treatment and management effects of cardiovascular diseases such as atrial fibrilla-tion,heart failure,coronary heart disease,and hypertension,showing broad development prospects and application space.This article will provide a brief introduction to representative DCT in the global cardiovascular disease field,and look for-ward to the application prospects of this model,providing reference and guidance for accelerating the development of cardio-vascular DCT in China.

Objective·To measure the parameters of the uterine artery,umbilical artery and middle cerebral artery in a rat model of preeclampsia(PE)by Doppler ultrasound,and compare the pathological changes in placental blood vessels and pregnancy outcomes,in order to provide an effective method and reference for evaluating placental function in PE animal models.Methods·PE(n=8)and normal pregnancy(NP,n=8)groups in Sprague-Dawley(SD)rat models were established by intraperitoneal injections of N'-nitro-L-arginine methylesterhydrochloride(L-NAME)and 0.9%sodium chloride solution.Blood pressure and proteinuria indexes were detected to evaluate whether the model was successfully established.On gestational day 19(GD19),Doppler ultrasound was utilized to measure the parameters of the uterine artery,umbilical artery and the fetal middle cerebral artery in both the PE and NP groups.After termination of the pregnancies,placental function was evaluated through the pathology of placental blood vessels and the quality of the fetuses and placentas.Results·In the PE group,both blood pressure(GD15:P=0.001;GD19:P=0.001)and proteinuria(GD15:P=0.001;GD19:P=0.001)were significantly higher than those in the NP group.The pulsatility index(PI)of the umbilical artery and uterine artery was notably elevated in the PE group compared to the NP group(both P=0.000).Furthermore,the resistance index(RI)of the fetal middle cerebral artery was significantly lower than that in the PE group(P=0.000).While the number of fetal rats did not differ significantly,the quality of placental and fetal rats was notably lower in the PE group(P=0.006 and P=0.000,respectively).Immunohistochemical staining of placental tissue revealed that the number of placental micro vessel densities in the PE group was less than that in the NP group(P=0.001).Correlation analysis revealed that placental micro vessel density,fetal quality and placental quality were inversely related with the RI of the umbilical artery and the PI and RI of the uterine artery,and positively correlated with the S/D,PI and RI of the fetal middle cerebral artery(all P<0.05).Conculsion·Doppler ultrasound assessment of the uterine artery,umbilical artery and middle cerebral artery indices in L-NAME-induced PE rat models effectively reflects pregnancy outcomes and placental vascular pathology.This method is valuable for evaluating placental vascular perfusion in PE rat models,offering practicality and convenience for research involving animal models.

Detailed characterizations of genomic alterations have not identified subtype-specific vulnerabilities in adult gliomas. Mapping gliomas into developmental programs may uncover new vulnerabilities that are not strictly related to genomic alterations. After identifying conserved gene modules co-expressed with EGFR or PDGFRA (EM or PM), we recently proposed an EM/PM classification scheme for adult gliomas in a histological subtype- and grade-independent manner. By using cohorts of bulk samples, paired primary and recurrent samples, multi-region samples from the same glioma, single-cell RNA-seq samples, and clinical samples, we here demonstrate the temporal and spatial stability of the EM and PM subtypes. The EM and PM subtypes, which progress in a subtype-specific mode, are robustly maintained in paired longitudinal samples. Elevated activities of cell proliferation, genomic instability and microenvironment, rather than subtype switching, mark recurrent gliomas. Within individual gliomas, the EM/PM subtype was preserved across regions and single cells. Malignant cells in the EM and PM gliomas were correlated to neural stem cell and oligodendrocyte progenitor cell compartment, respectively. Thus, while genetic makeup may change during progression and/or within different tumor areas, adult gliomas evolve within a neurodevelopmental framework of the EM and PM molecular subtypes. The dysregulated developmental pathways embedded in these molecular subtypes may contain subtype-specific vulnerabilities.

Objective:To investigate the clinical effects of Tongdu Qishen acupuncture combined with traditional Chinese medicine decoction on post-stroke depression in patients. Methods:Sixty-two patients with post-stroke depression who received treatment in Zhongda Hospital of Southeast University from October 2020 to April 2022 were included in this study. They were randomly treated either with traditional Chinese medicine decoction (control group, n = 31) or Tongdu Qishen acupuncture combined with traditional Chinese medicine decoction (combined group, n = 31) based on routine medication. All patients were treated for 4 weeks. Depressive state, neurological function, and activities of daily living were compared between the two groups. Results:Before treatment, there were no significant differences in the Hamilton Depression Scale (HAMD) score, National Institutes of Health Stroke Scale (NIHSS) score, and Barthel index between the two groups (all P > 0.05). After 4 weeks of treatment, the HAMD and NIHSS scores in the control group were (13.88 ± 3.92) points and (8.56 ± 1.82) points, respectively, and they were (8.72 ± 2.48) points and (6.67 ± 1.14) points in the combined group. There were significant differences in HAMD and NIHSS scores between the two groups ( t = 2.14, 2.43, both P < 0.05). The Barthel index in the combined group was (69.53 ± 13.29) points, which was significantly higher than (62.34 ± 15.67) points in the control group ( t = 2.23, P < 0.05). Conclusion:Tongdu Qishen acupuncture combined with traditional Chinese medicine decoction can reduce depressive symptoms and improve neurological function and activities of daily living in patients with post-stroke depression. The combined therapy has obvious efficacy in the treatment of post-stroke depression.

Traumatic brain injury(TBI)is a multifaceted disease with a complex pathogenesis for which there are currently no effective therapeutic interventions.Research has shown that bone marrow mesenchymal stem cell-derived extracellular vesicles(BMSC-EVs)may play a therapeutic role in TBI.They attenuate neuroinflammatory responses at the site of the lesion and promote neurovascular regeneration.However,the exact mechanisms underlying their actions are not fully understood.This article aims to review the current state of research on the therapeutic mechanisms of BMSC-EVs in TBI.It also aims to discuss possible future research directions and potential clinical applications of BMSC-EVs.

Objective: To summarize the clinical manifestations of IgG4-related diseases in the head and neck, explore treatment methods. Methods : The clinical data of 21 patients diagnosed with IgG4-related diseases were retrospectively analyzed. The clinical data and the results of glucocorticoid and immunosuppressive therapy were studied retrospectively. Results: All patients had swollen sclerotic masses, and CT showed irregular high-density masses with uniform enhancement in the enlarged glands. Some patients had mucosal thickening and mass-like changes in theoral cavity, nose, sinuses, throat and other tissues, and most of the patients had cervical lymphadenopathy and elevated serum IgG4 levels (≥ 1.35 g/L). Histopathological examination of affected exosine glands and affected mucosa and lymph nodes in all patients showed infiltration of lymphocytes, plasma cells and IgG4+ plasma cells. In 21 patients, the mass in the affected glands and mucosa (including head, neck and other tissues) disappeared, and the clinical symptoms were relieved after the application of glucocorticoids. However, with a reduction in glucocorticoids, the mass recurred or even worsened. Conclusion For patients with a single mass in the submandibular gland, parotid gland and other salivary glands, as well as lymph node enlargement, CT is the first choice to identify the nature of gland neoplasms. Combined with pathological examination, related auxiliary examination and peripheral blood examination are also needed to obtain a definitive diagnosis. Glucocorticoid therapy is used to achieve a good prognosis, and long-term follow-up and timely adjustment of medication regimens are required.

Objective:To retrieve relevant evidence for early enteral nutrition support in patients after gastric cancer surgery and summarize the best evidence, so as to provide evidence-based evidence for clinical implementation of postoperative enteral nutrition management for gastric cancer.Methods:Evidence-based questions were established according to PIPOST principles, UpToDate, Cochrane Library, Joanna Briggs Institute Library, BMJ Best Practice, Agency for Healthcare Research and Quality website, Medlive, European Society for Clinical Nutrition and Metabolism website, American Society for Parenteral and Enteral Nutrition website, Embase, Medline, PubMed, SinoMed, Wanfang Database, China National Knowledge Infrastructure were searched according to the "6S" evidence model. The retrieval period of every database was from January 1, 2016 to May 31, 2021. The Evidence Pre-Grading and Evidence Recommendation Grading System (2014) of Australian Joanna Briggs Institute Evidence-Based Health Care Center was used to extract evidence from the literature that met the quality standards, determine the evidence grading and recommendation level and form the best evidence.Results:A total of 317 literatures were retrieved, and 10 literatures were included, including 1 guideline, 4 expert consensus and 5 systematic reviews. The 10 evidences were summarized from 4 aspects, including indication evaluation, timing management, route and preparation management and risk management.Conclusions:Current evidence shows that early enteral nutrition is safe and feasible in patients after gastric cancer surgery. In the process of implementing enteral nutrition, medical staff should fully evaluate the indications and needs of patients and make clear and prudent choices for nutritional support channels and preparations of patients, so as to form the best evidence and clinical management programs for early enteral nutrition support for patients after gastric cancer surgery and accelerate postoperative recovery of patients.

Objective:To survey the status of illness and consultation within two weeks among residents in a community in Chengdu.Methods:A multi-stage stratified random sampling was used to carry out a questionnaire survey among the residents in a community in Chengdu during March to April 2019. The disease status, disease severity and consultation within two weeks were surveyed, and influencing factors of two-week illness were analyzed with logistic regression.Results:Among 2 714 participants, 715 had illness (900 times) within two weeks, with a two-week prevalence rate of 26.3%. The main symptoms were dizziness (6.4%, 58/900), cough (6.2%, 56/900), lumbago and leg pain (4.9%, 44/900), palpitations (3.3%, 30/900) and headache (3.1%, 28/900). The three most common diseases were hypertension (38.3%, 345/900), diabetes (19.3%, 174/900) and common cold (6.4%, 58/900). In this survey, the rate of two-week in bed was 20.6‰(56/2 714), and the rate of two-week off work was 4.8‰(13/2 714). Age, gender, education level and work status were the influencing factors of the illness in two weeks ( P<0.05). The choice of medical institution was also different among residents. Conclusion:The survey suggest that primary care should focus on the key groups of residents in the community such as elderly, women, low education level, retirement and unemployed; and it is necessary to strengthen the primary care institutions and two-way referral system of health care.
