Objective: To observe the clinical efficacy and safety of Yiqi Tongluo Decoction in the intervention of early traditional Chinese medicine (TCM) syndromes after ischemic cerebrovascular disease (ICVD) intervention. Methods: From October 2020 to July 2023, a randomized, double-blind, placebo-controlled study was conducted to include 60 patients with qi deficiency, blood stasis, and phlegm obstruction syndrome after ICVD interventional therapy. They were assigned to the Yiqi Tongluo Decoction treatment group (30 cases) and the TCM placebo routine treatment control group (30 cases) according to the randomized block design. Both groups received routine standardized treatment of Western medicine, including dual antiplatelet, lipid regulation, and control of risk factors for cerebrovascular disease. The treatment group was treated with Yiqi Tongluo Decoction based on the control group. The course of treatment was 60 days and follow-up was carried out 2 and 6 months after the operation. The improvement of qi deficiency syndrome, blood stasis syndrome, phlegm syndrome score and TCM syndrome score, modified Rankin score (mRS), Barthel index (BI) score, Fatty acid-binding protein 4 (FABP4) level, incidence of transient ischemic attack (TIA) and ischemic stroke (IS) and incidence of adverse reactions, Head and neck CT angiography (CTA) or digital subtraction angiography (DSA) examination were collected. The clinical efficacy of the patients 2 months after the operation was taken as the main outcome index to preliminarily evaluate the early and long-term efficacy of Yiqi Tongluo Decoction after the ICVD intervention. The early and long-term clinical efficacy and safety of Western medicine standardized treatment combined with TCM Yiqi Tongluo Decoction on patients with qi deficiency, blood stasis and phlegm obstruction syndrome after ICVD intervention were evaluated. The safety of Yiqi Tongluo Decoction in the treatment of patients after ICVD intervention with white blood cell (WBC), C-reactive protein (CRP), fibrinogen (FIB), plasminogen time (PT), recurrence of cerebral ischaemia and restenosis in patients at 2 and 6 months after treatment were evaluated. Results: Compared to the control group, the TCM syndrome scores for qi deficiency, blood stasis and phlegm syndrome in the treatment group reduced significantly, the clinical efficacy improved significantly, the mRS score and FABP4 were reduced, and the BI score was increased. Adverse events such as cerebral ischaemia were fewer in the treatment group than in the control group, but the difference was not statistically significant; levels of CRP, WBC and PT were reduced, and levels of FIB were reduced at 6 months post-treatment, all P<0.01, and images were intuitively compared. The treatment group was superior to the control group. Conclusion Yiqi Tongluo Decoction combined with Western medicine standard treatment can improve the early clinical efficacy of ICVD patients with qi deficiency, blood stasis and phlegm obstruction syndrome after interventional surgery, improve neurological impairment and daily living ability, reduce the state of qi deficiency syndrome, blood stasis syndrome and phlegm syndrome after interventional surgery, and improve the clinical efficacy of TCM. At the same time, it can reduce the level of FABP4, the target of atherosclerosis and restenosis after interventional surgery, reduce the level of inflammation after interventional surgery in patients with ICVD, regulate coagulation function, and reduce the incidence of long-term recurrence of cerebral ischemia after interventional surgery, with good safety.

Dry eye(DE)is a multifactorial ocular surface disorder arising from numerous pathologies. The pathogenesis of DE includes immune inflammation, oxidative stress, changes in tear film composition, corneal nerve abnormalities, and meibomian gland dysfunction. Among them, the immune inflammatory response is the most crucial in the pathogenesis of DE, which is regulated by both innate and acquired immune responses on the ocular surface. Multiple environmental stresses trigger the ocular surface innate immune response leading to corneal epithelial cell damage and inflammation and activate acquired immunity to participate in the ocular surface immune inflammatory response. Currently, multiple immune cells and inflammatory factors have been shown to be involved in the occurrence and development of DE. This article reviewed the immune progress and focused on the initiation and maintenance of acquired immunity in DE. Through the analysis of the latest viewpoints and research hot spots, we systematically introduced the immunomodulating mechanism underlying the mechanisms of the pathogenesis of DE and provided references for the prevention and treatment of DE.

The findings suggest technical rationality and operability of relevant standard should be considered when under revision, and standard training and supervision management should be strengthened, with the aim of teaching environment improvement.

Objective To explore the efficacy of retropubic midurethral synthetic sling(RMUS)in relieving urgency and urge urinary incontinence(UUI)symptoms in patients with mixed urinary incontinence(MUI).Methods Clinical data of 44 female MUI patients treated with RMUS during Jan.2018 and Dec.2020 in Shanghai Renji Hospital were retrospectively analyzed.All patients had positive results in stress test and Marshall-Marchetti test before operation,and 27 of them completed ICIQ-FLUTS-LF questionnaire.Urodynamic(UDS)tests suggested that 9 patients(20.5％)presented detrusor overactivity(DO).During RMUS procedure,the tension of the sling was adjusted based on the anatomical landmarks.The postoperative efficacy and improvement of urinary incontinence were analyzed.Results The patients aged(58.59±9.08)years,with a body mass index of 24.71±2.77.Among the 40 patients who completed telephone interview 2 years after surgery,the subjective cure rate was 85.0％(34/40).Among the 27 patients with records of questionnaires before and after surgery,there were significant differences in the incidence of urine leakage[100％(27/27)vs.18.5％(5/27)],stress urinary incontinence(SUI)[100％(27/27)vs.18.5％(5/27)]and UUI[70.4％(19/27)vs.29.6％(8/27)](P＜0.05).However,no statistical differences were found regarding nocturia voiding episode(≥1 times),urgency,dysuria,hesitancy,strain to void,intermittent stream and enuresis(P＞0.05).Based on preoperative UDS test,there were significant differences regarding the subjective cure rate in patients with or without preoperative DO[55.6％(5/9)vs.93.5％(29/31)],incidence of SUI[66.7％(4/6)vs.4.8％(1/21)],and UUI[66.7％(4/6)vs.19.0％(4/21)](P＜0.05),while there was no statistical difference regarding urgency[66.7％(4/6)vs.33.3％(7/21)](P＞0.05).Conclusion RMUS is effective in treating MUI patients with positive stress test and Marshall-Marchetti test results,which can relieve SUI and UUI symptoms,but has no effects on urgency symptoms.DO on preoperative urodynamics results in poorer subjective outcomes.

[Objective] To explore the application of pelvic floor ultrasonography in the treatment of mixed urinary incontinence (MUI) by transvaginal retropubic midurethral synthetic sling (RMUS), in order to understand the relationship between the morphological changes of pelvic floor structures and the efficacy of RMUS. [Methods] Clinical data of 44 female MUI patients undergoing RMUS during Jan.2018 and Dec.2020 were retrospectively analyzed.Urodynamics detected detrusor overactivity (DO) in 9 cases (20.5%). During RMUS procedure, the tension of the sling was adjusted based on the anatomical landmarks. The changes of ultrasonic parameters before and after operation, the relationship between the ultrasonic results, surgical efficacy and urodynamic results were analyzed. [Results] The patients averaged (58.59±9.08) years, with the body mass index being 24.71±2.77.The subjective cure rate was 91.3% (21/23) 3 months after surgery, and 85.0% (34/40) 2 years after surgery.Pelvic floor ultrasonography showed significant differences in posterior urethravesical angel at rest and during Valsalva, bladder neck descent distance and the rate of urethral funneling during Valsalva (P<0.05). According to the group analysis of the preoperative ultrasonic results, there was no statistical significance in the subjective cure rate between the funneling group and the non-funneling group during Valsalva, and the bladder neck non downward group/mild downward group/moderate downward group/severe downward group during Valsalva 3 months and 2 years after surgery (P>0.05). At 3-month follow-up, all pre-RMUS urethral funneling during Valsalva disappeared in patients without preoperative DO.Comparatively, 50.0% (3/6) urethral funneling still presented in DO patients, who had a lower cure rate (55.6%, 5/9) at the 2-year follow-up. [Conclusion] RMUS can reduce the posterior urethravesical angel at rest and during Valsalva, reduce bladder neck descent distance and the rate of urethral funneling during Valsalva in MUI patients, which can enhance urinary continence.There seems to be a correlation between DO and urethral funneling during Valsalva, while RMUS may potentially reverse the two markers.

As the main product of anaerobic or aerobic glycolysis,lactic acid has long been considered to be only the metabolic waste of this process,but now researches have are gradually revealing that lactic acid,as an important signaling molecule,plays a key immune regulatory role by acting on lactic acid transporters,lactate receptors and intracellular direct sensors in immune cells.In chronic inflammatory diseases,lactic acid helps maintain a pro-inflammatory environment that encourages immune cells to remain at the site of inflammation.In the event of infection,lactic acid impairs host immunity.In the tumor microenvironment(TME),the increase in lactic acid production and the resulting TME acidification promote tumor growth and invasion,and inhibit the body's immune response to tumor antigens.This review focuses on the recent research progress on the role of lactic acid in immune regulation.

Objective To study the influence of ANGPTL8 in lipopolysaccharide(LPS)-induced hepatic lipid deposition.Methods Male wild-type(WT)and ANGPTL8 knockout mice at 6-8 weeks were used to induce sepsis models by intrabitoneal injection of LPS(10 mg/kg).qPCR and immunofluorescence were used to detected the mRNA and protein expression of ANGPTL8 in liver tissue and HepG2 cells respectively;The contents of alanine aminotransferase(ALT),aspartate aminotransferase(AST)in serum and the triglyceride(TG)and malondialdehyde(MDA)in liver homogenate were detected by kits;the histopathological changes of liver tissue were analyzed through HE staining.Lipids accumulation in liver were detected by oil red O staining.The apoptosis of liver was determinated by TUNEL staining.RNA-seq was used to analyzing the differentially expressed genes in the liver tissue of WT and ANGPTL8 KO mice,and the qPCR and Western Blot were used to verify the differential expressed genes.Results The expression of ANGPTL8 in the liver was significantly upregulated at 48 hours after LPS stimulation.Compared with WT mice,the hepatic lipid deposition,steatosis,and apoptosis were significantly alleviated in liver of ANGPTL8 KO mice,the ALT and AST levels in serum and the TG and MDA content in liver homogenate of ANGPTL8 KO mice were also reduced significantly.The expression of caveolin-1(CAV1)in liver of ANGPTL8 KO mice was significantly higher than that of WT mice.Conclusions LPS promoted the expression and secretion of ANGPTL8 in liver tissue,and ANGPTL8 increased hepatic lipid deposition and peroxidation by inhibiting the expression of CAV1.

Risk perception in patients with cardiovascular disease (CVD) can predict their adoption of health behaviors. A significant discrepancy between perceived risk and objective risk estimates can adversely affect individuals' risk response behaviors. This paper introduces the status quo of risk perception bias among CVD patients and analyzes the influencing factors from demographic factors, disease risk factors, individual psychological factors, socio-cultural factors, risk communication, and risk characteristics. It summarizes intervention strategies to reduce risk perception bias, aiming to enhance healthcare professionals' understanding of this issue in CVD patients and provide a reference for developing reasonable intervention measures in the future.

Lipids have been found to modulate tumor biology, including proliferation, survival, and metastasis. With the new understanding of tumor immune escape that has developed in recent years, the influence of lipids on the cancer-immunity cycle has also been gradually discovered. First, regarding antigen presentation, cholesterol prevents tumor antigens from being identified by antigen presenting cells. Fatty acids reduce the expression of major histocompatibility complex class I and costimulatory factors in dendritic cells, impairing antigen presentation to T cells. Prostaglandin E2 (PGE2) reduce the accumulation of tumor-infiltrating dendritic cells. Regarding T-cell priming and activation, cholesterol destroys the structure of the T-cell receptor and reduces immunodetection. In contrast, cholesterol also promotes T-cell receptor clustering and relative signal transduction. PGE2 represses T-cell proliferation. Finally, regarding T-cell killing of cancer cells, PGE2 and cholesterol weaken granule-dependent cytotoxicity. Moreover, fatty acids, cholesterol, and PGE2 can improve the activity of immunosuppressive cells, increase the expression of immune checkpoints and promote the secretion of immunosuppressive cytokines. Given the regulatory role of lipids in the cancer-immunity cycle, drugs that modulate fatty acids, cholesterol and PGE2 have been envisioned as effective way in restoring antitumor immunity and synergizing with immunotherapy. These strategies have been studied in both preclinical and clinical studies.

Both cholinergic dysfunction and protein citrullination are the hallmarks of rheumatoid arthritis (RA), but the relationship between the two phenomena remains unclear. We explored whether and how cholinergic dysfunction accelerates protein citrullination and consequently drives the development of RA. Cholinergic function and protein citrullination levels in patients with RA and collagen-induced arthritis (CIA) mice were collected. In both neuron-macrophage coculture system and CIA mice, the effect of cholinergic dysfunction on protein citrullination and expression of peptidylarginine deiminases (PADs) was assessed by immunofluorescence. The key transcription factors for PAD4 expression were predicted and validated. Cholinergic dysfunction in the patients with RA and CIA mice negatively correlated with the degree of protein citrullination in synovial tissues. The cholinergic or alpha7 nicotinic acetylcholine receptor (α7nAChR) deactivation and activation resulted in the promotion and reduction of protein citrullination in vitro and in vivo, respectively. Especially, the activation deficiency of α7nAChR induced the earlier onset and aggravation of CIA. Furthermore, deactivation of α7nAChR increased the expression of PAD4 and specificity protein-3 (SP3) in vitro and in vivo. Our results suggest that cholinergic dysfunction-induced deficient α7nAChR activation, which induces the expression of SP3 and its downstream molecule PAD4, accelerating protein citrullination and the development of RA.
