It is proposed that cold pathogen plays an important promoting role in the onset and progression of hyperlipidemia. External exposure to cold， the gradual generation of internal cold， and the covert consumption of yang qi caused by modern lifestyle factors may all provide a pathological basis for the development of hyperlipidemia. Based on the pathogenic characteristics of cold， namely its tendency to damage yang， induce stagnation， and cause contraction， this paper suggests that the treatment of hyperlipidemia should focus on warming and tonifying， warming and resolving， and warming and unblocking， respectively. This provides a theoretical reference for the diagnosis and treatment of hyperlipidemia with traditional Chinese medicine.

OBJECTIVE To provide a reference for anticoagulant therapy and vaginal bleeding management during medical abortion in patients with missed abortion after aortic mechanical valve replacement surgery. METHODS Clinical pharmacists conducted pharmaceutical monitoring on a patient with missed abortion after aortic mechanical valve replacement surgery， and analyzed the correlation between warfarin use and abortion. In response to gingival bleeding and an increase in the international normalized ratio （INR） after taking mifepristone， clinical pharmacists recommended discontinuing warfarin based on bleeding risk and INR changes； for the selection of sex hormones after missed abortion， clinical pharmacists suggested that estradiol gel combined with progesterone should be used in sequential treatment， supplemented by Xian yimucao capsules， to accelerate the elimination of residual tissue and congestion in uterine cavity. RESULTS The physician followed the advice of the clinical pharmacist and did not prolong the patient’s hospital stay due to excessive vaginal bleeding during treatment. Warfarin treatment was restarted on the day of discharge， and INR remained stable within the target anticoagulation range after discharge without any adverse events such as thromboembolism. CONCLUSIONS In patients with missed abortion after aortic valve replacement surgery， mifepristone may enhance the anticoagulant effect of warfarin and increase the risk of bleeding during medical abortion. It is recommended to discontinue warfarin before medication. Clinical pharmacists play a crucial role in the development of anticoagulation plans， identification of drug-drug interactions， assessment of bleeding risks， and selection of postoperative sex hormones. Through full pharmaceutical monitoring， they ensure the safety of patients’ medication.

ObjectiveTo explore the potential mechanism by which Huoxue Wentong prescription （HXWT） ameliorates post-myocardial infarction （MI） ventricular remodeling by regulating endothelial-to-mesenchymal transition （EndMT） via the hypoxia-inducible factor-1α （HIF-1α）/transforming growth factor-β₁ （TGF-β₁）/periostin （POSTN） signaling pathway. MethodsEighty SPF-grade male Sprague-Dawley rats were randomly assigned to a sham-operated group （n=10） and a modeling group （n=70）. The MI model was established by left anterior descending coronary artery ligation. Successfully modeled rats were further randomized into a model group， a sacubitril/valsartan （Entresto， 0.021 g·kg^-1） group， and low， medium， and high-dose （4.15， 8.30， and 16.60 g·kg^-1， respectively） HXWTF groups （n=10 per group）. From postoperative day 2， rats received HXWTF or sacubitril/valsartan by gavage once daily for 4 weeks， and those in sham and model groups received an equal volume of normal saline. After intervention， general conditions were assessed. Echocardiography was performed to measure the left ventricular ejection fraction （LVEF）， left ventricular fractional shortening （LVFS）， left ventricular end diastolic diameter （LVEDD）， and left ventricular end systolic diameter （LVESD）. Hematoxylin and eosin （HE） staining was employed to evaluate myocardial histopathology， and Masson's trichrome staining to assess myocardial fibrosis. Serum levels of B-type natriuretic peptide （BNP）， interleukin （IL）-6， IL-10， and matrix metalloproteinase-9 （MMP-9） were determined by enzyme-linked immunosorbent assay （ELISA）. Collagen type Ⅰ （ColⅠ） expression was assessed by immunohistochemistry. Immunofluorescence double staining was adopted to detect the expression of platelet endothelial cell adhesion molecule-1 （CD31） and α-smooth muscle actin （α-SMA）. Western blot was performed to quantify the expression of collagen type Ⅰ α2 （Col1A2）， VE-cadherin， CD31， α-SMA， HIF-1α， TGF-β₁， and POSTN. ResultsCompared with the sham group， the model group exhibited thinning and collapse of the left ventricular wall， decreased LVEF and LVFS and increased LVEDD and LVESD （P<0.01）， disrupted myocardial fibers with marked inflammatory cell infiltration， increased collagen deposition， enhanced ColⅠ immunoreactivity， elevate serum BNP， IL-6， and MMP-9 levels， a reduced IL-10 level （P<0.01）， downregulated expression of CD31 and VE-cadherin， and upregulated expression of α-SMA， Col1A2， HIF-1α， TGF-β₁， and POSTN （P<0.05，P<0.01）， accompanied by increased CD31/α-SMA co-localization. Compared with the model group， the sacubitril/valsartan group and all HXWTF groups showed improved ventricular wall structure， increased LVEF and LVFS， decreased LVEDD and LVESD， attenuated myocardial injury with reduced inflammatory infiltration and collagen deposition， declined serum BNP， IL-6， and MMP-9 levels， an elevated serum IL-10 level， upregulated expression of CD31 and VE-cadherin， downregulated expression of α-SMA， Col1A2， HIF-1α， TGF-β₁， and POSTN， and reduced CD31/α-SMA co-localization （P<0.05，P<0.01）. No significant differences were observed between the sacubitril/valsartan group and the medium- and high-dose HXWTF groups. ConclusionHXWTF may regulate the HIF-1α/TGF-β₁/POSTN pathway to inhibit EndMT， thereby ameliorating post-MI ventricular remodeling.

In recent years， hyperuricemia （HUA） has shown a rapidly increasing incidence and tends to occur in increasingly young people， with a wide range of cardiac， renal， joint， and cancerous hazards and all-cause mortality associations. Western medicine treatment has limitations such as large liver and kidney damage， medication restriction， and easy recurrence. The intestine is the major extra-renal excretion pathway for uric acid （UA）， and the intestinal microecology can be regulated to promote UA degradation. It offers great potential to develop UA-lowering strategies that target the intestinal microecology， which are promising to provide safer and more effective therapeutic approaches. Traditional Chinese medicine （TCM） can treat HUA via multiple targets and multiple pathways from a holistic view， with low toxicity and side effects. Studies have shown that intestinal microecology is a crucial target for TCM in the treatment of HUA. However， its specific mechanism of action has not been fully elucidated. Focusing on the key role of intestinal microecology in HUA， this review explores the relationship between intestinal microecology and HUA in terms of intestinal flora， intestinal metabolites， intestinal UA transporters， and intestinal barriers. Furthermore， we summarize the research progress in TCM treatment of HUA by targeting the intestinal microecology， with the aim of providing references for the development of TCM intervention strategies for HUA and the direction of future research.

Background: and Purpose Guillain–Barré syndrome (GBS) is an autoimmune-mediated disorder characterized by demyelinating or axonal injury of the peripheral nerve. Our aim is to determine whether serum amyloid A (SAA) is a biomarker of demyelinating injury and disease severity in patients with GBS. Methods: This study retrospectively enrolled 40 patients with either the demyelinating or axonal GBS and sex- and age-matched controls with other neurological diseases as well as healthy subjects. The demographic and clinical features at entry were collected. The serum levels of the SAA isoforms SAA1, SAA2, and SAA4 were determined in the patients with GBS and the controls using the enzyme-linked immunosorbent assay and analyzed for the associations between levels of different SAA isoforms and the clinical features of the patients. Results: The levels of SAA2 and SAA4 were significantly higher in patients with GBS than in both the other neurological disease controls and the healthy subjects (p<0.05 for all). The level of SAA1 did not differ between patients with GBS and the controls. The level of SAA2 was considerably higher in GBS patients with antecedent infection than in those without infection (p=0.020). The levels of different SAA isoforms were not associated with the disease severity or other clinical features of patients with GBS (p>0.05 for all). Conclusions Increased levels of SAA2 and SAA4 may only represent the acute inflammatory status and so cannot be utilized as biomarkers of the disease severity or demyelinating injury in patients with GBS.

Objective To explore the effects of physical activity(PA)on carotid intima-media thickness(CIMT)thickening in patients with type 2 diabetes mellitus(T2DM)with poor HbA1c control.Methods A total of 2505 T2DM inpatients with poor HbA1c control who visited the Endocrinology Department of the Integrated Traditional Chinese and Western Medicine Hospital Affiliated with Nanjing University of Traditional Chinese Medicine and Changzhou Second People's Hospital Affiliated with Nanjing Medical University from January 2019 to February 2022 were enrolled in this study.The patients were categorized into the mild-intensity PA(1～599 MET-min/w,n=795),moderate-intensity PA(600～1499 MET-min/w,n=1107)and high-intensity PA(≥1500 MET-min/w,n=603)based on the metabolic equivalence level(MET).Logistic regression was performed to analyze the relationship between PA and CIMT thickening.Statified analysis was used to investigate the effects of blood pressure(BP)and low-density lipoprotein cholesterol(LDL-C)target status on CIMT thickness in different PA groups.Results Restricted cubic spline plots showed a nonlinear relationship between PA levels and the risk of CIMT thickening(P<0.05).Logistic regression showed that with moderate-intensity PA as the control,while high-intensity PA was the influence factor of CIMT thickening(OR 1.581,95%CI 1.244～2.010,P<0.05).Statified analyses showed that under mild-intensity PA,using neither BP nor LDL-C on target as reference,achievement of either index and both were the influence factor of CIMT thickening.Using BP on target as reference,achievements of both indexes,achievements of neither of both indexes,and achievement of LDL-C only were the influence factor of CIMT thickening.Using LDL-C on target as reference,achievement of neither of them and achievement of BP only were the influence factor of CIMT thickening.Under high-intensity PA,achievement of both indexes was negatively associated with CIMT thickening.Conclusions Moderate-intensity PA is the recommended scheme to prevent CIMT thickening in T2DM patients whose HbA1c is not up to standard.Mild-intensity PA is not related to the risk of CIMT thickening,while high-intensity PA is positively related to the risk of CIMT thickening,and focusing on LDL-C compliance is particularly important to avoid CIMT thickening.

Autoimmunity and the activation of immune cells are closely related to the occurrence of chronic spontaneous urticaria, while the gut microbiota participates in multiple physiological activities including the regulation of the host's immunity. Gut microbiota in patients with chronic spontaneous urticaria has unique structural composition and metabolic features. Gut microbiota imbalance and secondary short-chain fatty acid deficiency may be important causes for the occurrence of the disease and aggravation of inflammation. Studies have shown that probiotics can improve the clinical manifestations of patients with urticaria. This review summarizes the research progress in the correlations of gut microbiota and short-chain fatty acids with chronic spontaneous urticaria.
