Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Septic shock is the primary cause of mortality in sepsis, with its core pathophysiological mechanism being severe ischemia and hypoxia in critical units—composed of microcirculation and the mitochondria of functional cells—resulting from disruptions in blood flow and oxygen flow following a dysregulated host response. Due to the systemically convergent yet clinically heterogeneous nature of the host response, current understanding and management strategies for hemodynamics remain inconsistent, often leading to inadequate resuscitation or overtreatment. To improve the quality of care, based on a systematic review of the "blood flow-oxygen flow" theory, an expert panel emphasizes reevaluating septic shock from an integrated perspective of blood flow and oxygen flow, and has formulated the Expert Consensus on Blood Flow and Oxygen Delivery Phenotyping and Clinical Management of Septic Shock (2025). The consensus proposes that clinical typing of blood flow-oxygen flow should comprehensively consider cardiac function, vascular tone, oxygen flow utilization status in critical units, and disease trajectory, while optimizing subtype identification by integrating host response phenotypes and artificial intelligence technologies. It advocates establishing a continuous assessment system through multi-site oxygen flow monitoring for organ perfusion, peripheral perfusion monitoring, and critical care ultrasound. Under the framework of the "critical care triangle", the consensus promotes the implementation of individualized, bundled management strategies, providing guidance for multiple management points to restore blood flow-oxygen flow matching, reduce the risk of organ failure, and decrease patient mortality.

Transdermal drug delivery offers advantages such as safety, convenience, and high patient compliance. However, the complex structure of the skin and significant individual variability, particularly the barrier function of the stratum corneum, result in generally low bioavailability for topical formulations. The formulation of topical drug products is complex, with numerous factors influencing quality, which requires strict control of product quality. Raman spectroscopy, as a non-destructive vibrational technique, combined with chemometric methods, imaging technology, and other spectroscopic techniques, can be applied to study the key quality attributes of topical drug formulations. The applications of Raman spectroscopy in studies of the crystal form, particle size distribution, excipient research, and in vitro transdermal experiments of topical drug formulations were summarized. In particular, it focused on the use of Raman spectroscopy in the selection of skin samples for in vitro permeation tests, the study of drug spatial distribution in the skin, and the interactions between drugs and the skin.

Heart failure （HF） is the end stage of various cardiovascular diseases， manifested as ventricular filling or impaired left ventricular ejection fraction （LVEF）. Type 2 diabetes mellitus （T2DM） is a metabolic disorder， mainly caused by insufficient insulin secretion and insulin resistance. The incidence rates of the two common clinical diseases are increasing year by year. HF and T2DM are mutually causal chronic diseases， and their mutual deterioration can form a HF-T2DM comorbidity. The comorbidity status significantly increases the mortality and readmission risk of patients， and seriously affects the quality of life of patients. At present， western medicine treatment mainly involves the use of anti HF drugs and hypoglycemic drugs， which can significantly alleviate the clinical symptoms of patients. However， these two categories of drugs are numerous in variety and differ in their mechanisms， and blind combination may produce adverse reactions. With its unique theoretical system， traditional Chinese medicine exhibits the advantages of multiple components， multiple targets， and high safety through traditional Chinese medicine monomers， Chinese patent medicine， traditional Chinese medicine compounds， and acupuncture， which significantly delays the development of HF-T2DM and shows great potential in clinical treatment. A large number of clinical studies have shown that the integrated traditional Chinese and western medicine in the treatment of HF-T2DM has a significant effect in improving cardiac function， controlling blood glucose levels， and improving the quality of life of patients. Based on relevant research at home and abroad， this paper reviewed the HF-T2DM pathogenesis， pharmacological effects， research status of traditional Chinese and western medicine， and early prevention strategies， and discussed current problems and future research directions， in order to provide new ideas and useful references for clinical prevention and treatment of HF-T2DM.

Objective:To discuss the characteristics of pulmonary function changes in the pediatric patients with Mycoplasma pneumoniae pneumonia(MPP),the effect of inhaled corticosteroids during the recovery phase on pulmonary function,and the improvement effects of different aerosolized medications on pulmonary function,and to clarify the significance of inhaled corticosteroids in the treatment of MPP pediatric patients during the recovery phase.Methods:A retrospective study was conducted.Sixty-nine MPP children who received inhaled corticosteroids after discharge were selected as treatment group.According to the different medications used after discharge,they were divided into steroid group(receiving inhaled corticosteroids alone,n=42)and combination group(receiving inhaled corticosteroids combined with inhaled long-acting bronchodilators,n=27).Additionally,30 children who did not receive aerosol therapy after discharge during the same period were selected as control group.The general data of the pediatric patients in various groups were collected.The pulmonary function parameters,including forced vital capacity(FVC),forced expiratory volume in the first second(FEV1),ratio of forced expiratory volume in 1 second to forced vital capacity(FEV1/FVC),peak expiratory flow(PEF),and maximal mid-expiratory flow(MMEF),were detected using pulmonary function equipment at the time of entering the recovery phase and 1 month after entering the recovery phase.The changes in pulmonary function of the pediatric patients between control group and treatment group were analyzed.Results:The pulmonary ventilation dysfunction in the MPP pediatric patients was mainly restrictive,followed by mixed.The pulmonary function could be normal or only show small airway dysfunction in some children.In both teatment and control groups,the second pulmonary function parameters including FVC,FEV1,PEF,maximal expiratory flow at 25%of forced vital capacity(MEF25),maximal expiratory flow at 50%of forced vital capacity(MEF50),maximal expiratory flow at 75%of forced vital capacity(MEF75),and MMEF of the pediatric patients were significantly increased compared with the first measurement(P<0.05).Compared with control group,the increase in FEV1/VC at the second measurement of the pediatric patients in treatment group was not significant(P>0.05).The differences in pulmonary function parameters showed an increasing trend in treatment group and control group.The differences in MEF25 and MMEF of the pediatric patients in the treatment group were higher than those in control group(P<0.05).The differences in pulmonary function parameters of the pediatic patients in both steroid group and the combination group showed an overall increasing trend.The differences in FVC,FEV1,FEV1/VC,MEF25,MEF50,and MMEF of the pediatric patients in steroid group were slightly higher than those in combination group.Compared with steroid group,the differences in PEF and MEF75 of the pediatric patients in combination group were slightly higher,but the differences were not statistically significant(P>0.05).The differences in MEF25,MEF50,and MMEF of the pediatric patients in steroid group were higher than those in control group(P<0.05).Conclusion:Both large and small airway functions can be affected in the pediatric patients with MPP,with restrictive ventilation dysfunction being predominant.Airway function can improve during the disease recovery phase.Inhaled corticosteroids during the recovery phase may have a positive therapeutic significance in promoting the recovery of pulmonary function,especially small airway function.The bronchodilators showed no significant effect on improving the pulmonary function during the recovery phase.Therefore,inhaled corticosteroids alone during the recovery phase may promote the recovery of pulmonary function in children with MPP.

As a typical "double heart" disease, the incidence rate of coronary heart disease with anxiety and depression is increasing year by year, which affects the long-term prognosis of the disease and the quality of life of patients. Based on the holistic concept of TCM, the theory of "heart-gallbladder connection" holds that there is a physiological and pathological relationship between the heart and gallbladder. At the same time, the theory of "heart-gallbladder connection" combined with modern medicine points out that disturbances in bile acid metabolism, gallbladder heart reflex, and brain gut bile acid axis are the three key nodes in the development of anxiety and depression in coronary heart disease. Starting from the theory of "heart-gallbladder connection", coronary heart disease combined with anxiety and depression is divided into three syndromes: heart deficiency and timidity, heart gallbladder stagnation, and heart gallbladder fire hyperactivity. Taking the principle of heart gallbladder harmony, the treatment of nourishing the heart and warming the gallbladder, regulating the heart and clearing the gallbladder, and clearing the heart and promoting bile flow is applied to provide a new clinical diagnosis and treatment approach for coronary heart disease combined with anxiety and depression.

Background::B-cell maturation antigen (BCMA)-directed chimeric antigen receptor T (CAR-T) therapy yield remarkable responses in patients with relapsed/refractory multiple myeloma (R/RMM). Circulating tumor DNA (ctDNA) reportedly exhibits distinct advantages in addressing the challenges posed by tumor heterogeneity in the distribution and genetic variations in R/RMM.Methods::Herein, the ctDNA of 108 peripheral blood plasma samples from patients with R/RMM at the First Affiliated Hospital, School of Medicine, Zhejiang University was thoroughly investigated before administration of anti-BCMA CAR-T therapy to establish its predictive potential. Flow cytometry is used primarily to detect subgroups of T cells or CAR-T cells.Results::In this study, several tumor and T cell effector-mediated factors were considered to be related to treatment failure by an integrat analysis, including higher percentages of multiple myeloma (MM) cells in the bone marrow ( P = 0.0125), lower percentages of CAR-T cells in the peripheral blood at peak ( P = 0.0375), and higher percentages of CD8 + T cells ( P = 0.0340). Furthermore, there is a substantial correlation between high ctDNA level (>143 ng/mL) and shorter progression-free survival (PFS) ( P = 0.007). Multivariate Cox regression analysis showed that high levels of ctDNA (>143 ng/mL), MM-driven high-risk mutations (including IGLL5 [ P = 0.004], IRF4 [ P = 0.024], and CREBBP [ P = 0.041]), number of multisite mutations, and resistance-related mutation ( ERBB4, P = 0.040) were independent risk factors for PFS. Conclusion::Finally, a ctDNA-based risk model was built based on the above independent risk factors, which serves as an adjunct non-invasive measure of substantial tumor burden and a prognostic genetic feature that can assist in predicting the response to anti-BCMA CAR-T therapy.

Cervical chylous leakage is rare after central lymph node dissection for thyroid cancer, and the coexistence of chylothorax is even more uncommon. This article reports a case of a 39-year-old female patient who underwent total thyroidectomy and left central lymph node dissection for papillary thyroid carcinoma complicated by follicular adenoma. On the second postoperative day, the patient developed white, milky drainage from the neck, suggesting chylous leakage, and experienced mild chest tightness, cough, and low-grade fever. Chest CT revealed bilateral pleural effusion, with the left side being more severe. On the third day, ultrasound-guided left-sided pleural puncture and drainage were performed and hydrothorax triglycerides and total cholesterol levels were measured, chylothorax were diagnosed as a result.After conservative treatment including a low-fat diet, fasting, nutritional support, neck pressure dressing and negative pressure suctionand closed chest drainage, the patient's condition improved rapidly. The patient was discharged on the 8th postoperative day with full recovery. No recurrence has been observed during follow-up to date.
