ObjectiveTo investigate the protective effect and mechanism of Wendan Ningxin granules （WNG） on susceptibility to atrial fibrillation （AF） in mice with inflammatory injury. Methods100 C57BL/6 mice were divided into a blank control group， a model group， a low-dose WNG group （2.34 g·kg^-1·d^-1）， a high-dose WNG group （4.68 g·kg^-1·d^-1）， and an amiodarone positive control group （0.091 g·kg^-1·d^-1）， with 20 mice in each group. Except for the blank control group， mice in other groups received intraperitoneal injections of lipopolysaccharide （LPS） to establish an inflammatory injury model. Treatment groups received continuous intragastric administration of their respective interventions for four weeks. During the fourth week， the treatment groups received LPS injections concurrently with their treatments. The blank control and model groups received distilled water （10 mL·kg^-1·d^-1） by gavage， with a gavage volume of 10 mL·kg^-1 for all groups， once daily. Hematoxylin-eosin （HE） staining and Sirius red staining were used to observe atrial tissue morphology and fibrosis degree. Immunohistochemistry was used to assess the expression of α-smooth muscle actin （α-SMA） in mouse atrial tissue. Electrophysiological detection was performed using a multi-channel electrophysiology mapping system to measure AF inducibility， AF duration， and atrial effective refractory period （AERP）. High-resolution optical mapping was used to measure action potential duration （APD） dispersion， conduction heterogeneity index， and calcium transient （CaT） dispersion. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect mRNA expression of proteins related to diastolic calcium leakage in mouse atria： Ca²⁺/calmodulin-dependent protein kinase Ⅱ（CaMKⅡ）， ryanodine receptor 2（RyR2）， sarco/endoplasmic reticulum Ca²⁺-ATPase （SERCA）， and sodium-calcium exchanger （NCX）. Western blot analysis was performed to detect the expression of CaMKII， RyR2， SERCA， and NCX proteins in myocardial tissue from each group. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum levels of inflammatory factors interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α）. ResultsPathological staining results showed that compared with the blank control group， the model group exhibited disrupted atrial tissue structure， inflammatory cell infiltration， atrial fibrosis， and diffuse infiltration of numerous brown α-SMA positive cells in the atrial interstitium （P<0.01）. AF could be induced by electrical stimulation with a longer duration. AERP was shortened， while APD dispersion， conduction heterogeneity index， and CaT dispersion were increased （P<0.01）. The expression of proteins associated with diastolic calcium leakage， including CaMKⅡ， RyR2， and NCX1， showed elevated mRNA and protein levels， whereas SERCA2a mRNA and protein expression decreased （P<0.05）. Serum levels of inflammatory factors IL-1β and TNF-α were elevated （P<0.01）. Compared with the model group， intervention with WNG alleviated cardiac structural damage， reduced inflammatory cell infiltration， improved atrial fibrosis， and reduced the diffuse infiltration of α-SMA positive cells （P<0.01）. AF inducibility and AF duration upon electrical stimulation were significantly reduced （P<0.05）， AERP was prolonged （P<0.05）， mRNA and protein expression of CaMKⅡ， RyR2， and NCX1-proteins associated with diastolic calcium leakage-were reduced， whilst mRNA and protein expression of SERCA2a increased （P<0.05）， and serum levels of IL-1β and TNF-α were decreased （P<0.01）. ConclusionBoth low‑ and high‑dose WNG can effectively reduce susceptibility to inflammation-related AF. The mechanism by which WNG reduce AF susceptibility may be related to regulating proteins involved in sarcoplasmic reticulum diastolic calcium leak， thereby improving cardiac electrical remodeling， and alleviating inflammation-induced myocardial fibrosis， thus improving cardiac structural remodeling.

ObjectiveTo investigate the therapeutic effects of modified Baoyuantang combined with Linggui Zhugantang on post-myocardial infarction heart failure in rats and its influence on NOD-like receptor pyrin domain-containing protein 3 （NLRP3）/gasdermin D （GSDMD）-mediated pyroptosis. MethodsSixty male SD rats were randomized into sham， model， low-， medium-， and high-dose （2.52， 5.04， 10.08 g·kg^-1， respectively） modified Baoyuantang combined with Linggui Zhugantang， and sacubitril/valsartan sodium （0.021 g·kg^-1） groups， with 10 rats in each group. Except the sham group， the other groups underwent left anterior descending coronary artery ligation for the modeling of myocardial infarction. The treatment groups were administrated with corresponding drugs by gavage， and the sham and model groups received an equal volume of normal saline. Administration began on the first day after successful modeling， once daily， for 4 weeks. Echocardiography was used to measure left ventricular ejection fraction （LVEF）， left ventricular fractional shortening （LVFS）， left ventricular end-diastolic and end-systolic diameters （LVIDd and LVIDs）， left ventricular posterior wall thicknesses at end-diastole and end-systole （LVPWd， LVPWs）， and left ventricular volumes at end-diastole and end-systole （LV Vold and LV Vols）. Cardiac mass index and heart weight-to-tibia length ratio were calculated. Hematoxylin-eosin （HE） staining and Sirius Red staining were performed to observe myocardial morphology and collagen deposition. Immunohistochemistry was employed to detect the expression of type I collagen （Collagen Ⅰ）， NLRP3， GSDMD， and interleukin-1β （IL-1β）. Transmission electron microscopy was used to observe the mitochondrial ultrastructure. Tetramethylrhodamine methyl ester （TMRM） staining was conducted to assess mitochondrial membrane potential （MMP） in cardiomyocytes. Real-time PCR was used to quantify the mRNA levels of NLRP3， cysteinyl aspartate-specific proteinase-1 （Caspase-1）， IL-1β， GSDMD， and interleukin-18 （IL-18） in the myocardial tissue. Western blotting was employed to determine the protein levels of NLRP3， Caspase-1， GSDMD， IL-1β， IL-18， nuclear factor kappa-B （NF-κB） p50， and NF-κB p65 in the myocardial tissue. Enzyme-linked immunosorbent assay （ELISA） was adopted to measure the serum levels of tumor necrosis factor-α （TNF-α）， IL-1β， and IL-6. ResultsCompared with the sham group， the model group showed increased LVIDd， LVIDs， LV Vold， LV Vols， cardiac mass index， and heart weight-to-tibia length ratio （P<0.05）， decreased LVPWs， LVEF， LVFS， and MMP （P<0.05）， evident myocardial inflammation， fibrosis， and mitochondrial damage， upregulated expression of NLRP3， Caspase-1， GSDMD， IL-1β， IL-18， NF-κB p50， and NF-κB p65， and elevated serum levels of TNF-α， IL-1β， and IL-6 （P<0.05）. Compared with the model group， modified Baoyuantang combined with Linggui Zhugantang reduced the LVIDd， LVIDs， LV Vols， cardiac mass index， and heart weight-to-tibia length ratio （P<0.05）， increased the LVPWs， LVEF， LVFS， and MMP （P<0.05）， alleviated myocardial inflammation and fibrosis， improved the mitochondrial structure and function， downregulated the expression of NLRP3， Caspase-1， GSDMD， IL-1β， IL-18， NF-κB p50， and NF-κB p65 （P<0.05）， and reduced the serum levels of TNF-α， IL-1β， and IL-6 （P<0.05）. ConclusionModified Baoyuantang combined with Linggui Zhugantang can ameliorate post-myocardial infarction ventricular remodeling and improve the cardiac function by reducing mitochondrial damage and inhibiting NLRP3/GSDMD-mediated pyroptosis.

Objective To explore the mechanism of Lidan Huatan Huoxue Decoction improving cognitive impairment caused by obesity based on metabolomics.Methods Twenty-four 6-week-old male SD rats were randomly divided into a normal group fed with regular diet(Con,n=6)and a modeling group fed with high-fat and high-sugar diet(n=18).Rats with a body mass that is 20%higher than the standard body mass of their age-matched peers fed with ordinary diet were considered to have a successful obese model established.The presence of cognitive impairment was assessed by Morris water maze and Barnes maze tests.After the obese-induced cognitive impairment(OICI)model was established,the modeling rats were randomly divided into a model group(Model,n=6),a donepezil group(Donepezil,n=6),and a Lidan Huatan Huoxue Decoction group(LHH,n=6).Drugs were administered to the donepezil and LHH groups by gastric intubation.The donepezil group was administered with a dose of 0.45 mg·(kg·d)-1,while the LHH group was administered with a dose of 25 g·(kg·d)-1.The normal and model groups were given the same volume of normal saline by gastric intubation for 8 weeks.Before the rats were sacrificed,water maze and Barnes maze experiments were conducted to assess cognitive function.After sacrifice,specimens were collected for biochemical and histological examination of liver tissue and brain tissue.Non-targeted metabolomic analysis using liquid chromatography-mass spectrometry(LC-MS)was performed on feces,serum,and brain tissue to analyze changes in differential metabolites in rats.Results Compared with the model group,the intervention of Donepezil and LHH effectively improved the learning and memory ability of OICI rats(P<0.05 or P<0.01),inhibited the overactivation of hippocampal microglia,and increased the number of hippocampal synaptic proteins.LHH improved metabolic-related indicators in OICI rats(P<0.05 or P<0.01).Metabolomic analysis showed significant differences in metabolites in feces,serum,and brain tissue between the model group and the normal group.The main affected pathways in fecal metabolites included steroid biosynthesis,caffeine metabolism,lysosome,vitamin B6 metabolism,phenylalanine,tyrosine,and tryptophan biosynthesis.The main affected pathways in serum metabolites included central carbon metabolism in cancer,pentose phosphate pathway,mineral absorption,protein digestion and absorption,and aminoacyl-tRNA biosynthesis.The main affected pathways in brain tissue metabolites included glycerophospholipid metabolism,β-alanine metabolism,propionic acid metabolism,niacin and nicotinamide metabolism,and caffeine metabolism.After LHH intervention,fecal metabolites showed the most significant changes,mainly involving vitamin B6 metabolism,vitamin digestion and absorption,histidine metabolism,fructose and mannose metabolism,and steroid biosynthesis.Conclusion LHH can improve cognitive impairment in obese rats mainly by regulating fecal metabolites.The main pathways involved include vitamin B6 metabolism,vitamin digestion and absorption,histidine metabolism,fructose and mannose metabolism,and steroid biosynthesis.Among them,vitamin B6 metabolism and vitamin digestion and absorption may be the most important pathways.

Objective:To investigate the effects of a single intravenous injection of low-dose esketamine during cesarean section on postpartum depression in primiparas.Methods:This study is a prospective randomized controlled trial involving 106 primiparas who underwent scheduled intrathecal anesthesia for cesarean section at Xi'an International Medical Center Hospital from January 2021 to December 2023. The participants were randomly assigned to either the control group or the observation group, with 53 women in each group, using a random number table method. Both groups received the same type and method of anesthesia. In the observation group, 5 minutes after the delivery of the fetus and the clamping of the umbilical cord, a low dose of esketamine (0.2 mg/kg, dissolved in 10 mL of 0.9% sodium chloride injection) was administered intravenously. The control group received an equivalent volume of 0.9% sodium chloride injection as a placebo. The score of the Edinburgh Postnatal Depression Scale at various postpartum time intervals (3, 7, 14, 30, and 42 days), the incidence of postpartum depression, and any adverse drug reactions occurring within 3 days postoperatively were compared between the two groups. Additionally, the score of the Visual Analog Scale (VAS) for contraction pain was assessed.Results:The scores of the Edinburgh Postnatal Depression Scale in the observation group at 3, 7, 14, 30, and 42 days postpartum were (6.23 ± 1.21), (5.82 ± 1.77), (6.14 ± 1.20), (5.33 ± 1.19), and (6.01 ± 1.23), respectively. These scores were significantly lower than those in the control group [(8.99 ± 1.28), (8.91 ± 2.11), (9.03 ± 1.94), (10.40 ± 2.68), (9.28 ± 1.84), t = 11.40, 8.16, 9.22, 12.58, 10.75, all P < 0.001]. The incidence of postpartum depression in the observation group at 7 and 14 days postpartum was significantly lower than that in the control group [3.77% (2/53) vs. 16.98% (9/53), 3.77% (2/53) vs. 15.09% (8/53), χ2 = 4.97, 3.97, P = 0.026, 0.046]. There was no statistically significant difference in the incidence of adverse drug reactions within 3 days postoperatively between the two groups of women who underwent scheduled intrathecal anesthesia for cesarean section [15.09% (8/53) vs. 11.32% (6/53), χ2 = 0.32, P = 0.566]. The scores of the Visual Analog Scale for contraction pain in the observation group at 3, 6, 12, and 24 hours postoperatively were (2.13 ± 0.28), (2.55 ± 0.33), (2.73 ± 0.35), and (3.06 ± 0.37), respectively. These scores were significantly lower than those in the control group [(4.35 ± 0.46), (5.43 ± 0.36), (5.68 ± 0.35), (5.26 ± 0.43), t = 30.01, 42.93, 43.38, 28.23, all P < 0.001]. Conclusions:A single intravenous injection of low-dose esketamine during cesarean section can effectively alleviate emotional distress in primiparas in the short term after surgery, which has significant clinical implications for reducing the incidence of postpartum depression.

AIM:To display the distribution of evi-dence in the field of Yiqifumai injection treatment for heart failure.METHODS:To retrieve relevant da-tabases such as CBM,CNKI,Wanfang,VIP,Co-chrane Library,PubMed,Embase,and Web of Sci-ence,and search for the China Clinical Trial Regis-try,ClinicalTrials.gov and collect clinical studies,sys-tematic evaluations,and guideline studies on the treatment of heart failure with Yiqifumai injection.The evidence map research method use a table to display the proportion of literature,sample size,co-morbidities,and quality evaluations of systematic evaluations.Use a pie chart to display the propor-tion distribution of research types,a line chart to describe publication trends,and a bubble chart to display the distribution of evidence.RESULTS:The overall number of articles on the treatment of heart failure with Yiqifumai injection is in a steady development stage.Clinical studies are mainly small sample,single center,short-term randomized controlled trials,with a sample size of 60-100 cases and an intervention duration of mostly 14 days.The underlying disease is mainly coronary heart dis-ease.Clinical research evidence tends to support the therapeutic effect of Yiqifumai injection com-bined with conventional Western medicine in im-proving heart failure patients'heart function and quality of life.However,there are also issues such as low overall quality of research,unreasonable clinical trial design,small sample size,incomplete selection of outcome indicators,low international recognition of certain outcome indicators,and lack of reporting on long-term outcomes The overall quality of randomized controlled trials andsystem-atic evaluation methodology is low.CONCLUSION:In the future,more large sample,multicenter clini-cal randomized controlled trials should be conduct-ed to obtain higher-level evidence-based medicine evidence to fully demonstrate the advantages of traditional Chinese medicine treatment,and pro-mote the common development of traditional Chi-nese medicine cardiology and evidence-based med-icine.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective:To investigate the effectiveness of gastric-soleal turndown flap and knotless anchor bridging fixation via a modified incision in the treatment of chronic Achilles tendon rupture of Myerson type Ⅲ.Methods:A retrospective case series study was conducted to analyze the clinical data of the 18 patients who had been treated at Department of Minimally Invasive Orthopedics, Zhengzhou Orthopaedic Hospital from February 2020 to July 2023 for chronic Achilles tendon rupture of Myerson type Ⅲ by means of gastric-soleal turndown flap and knotless anchor bridging fixation via a modified incision. There were 15 males and 3 females, with an age of (37.2±6.8) years. All patients suffered from unilateral injury, involving 13 left sides and 5 right sides. Their body mass index was (22.6±2.5) kg/m 2. The operation time, blood loss, incision length, wound healing and complications were documented. The ankle dorsiflexion and plantar flexion at the last follow-up were compared between the affected side and the healthy side. The American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and Achilles tendon total rupture score (ATRS) before operation were compared with those at the last follow-up. Results:All the 18 patients were followed up for (18.0±5.5) months. Their operation time was (69.1±5.2) minutes, blood loss (71.6±9.2) mL, incision at the broken end of the Achilles tendon (12.4±2.6) cm and incision at the proximal end (2.5±0.4) cm. At the last follow-up, the ankle dorsiflexion was 12.7°±1.9° and the ankle plantar flexion 35.2°±2.0° at the affected side, showing no significant difference from those at the healthy side (13.0°±2.1° and 34.7°±1.8°) ( P>0.05). The AOFAS ankle-hindfoot score was (89.4±3.4) points and the ATRS (85.3±3.2) points for the affected side at the last follow-up, showing significant improvements compared with the preoperative values [(54.2±4.2) points and (51.1±4.6) points] ( P<0.05). All the incisions healed at one stage after operation, with no such complications as incision infection or re-rupture of the Achilles tendon. One patient experienced mild pain at the anchor insertion site, but the pain disappeared 6 months after operation without any treatment. One patient had the symptoms of sural nerve injury which responded to 3 months of oral neurotrophic medication. Conclusion:In the treatment of chronic Achilles tendon rupture of Myerson type Ⅲ, gastric-soleal turndown flap and knotless anchor bridging fixation via a modified incision can result in limited invasion, a low incidence of complications, and definite effectiveness.

Objective To investigate the predictive value of pan-immune-inflammation value(PIV),blood urea nitrogen to albumin ratio(BAR),collateral circulation and National Institutes of Health stroke scale(NIHSS)score for disease progression and short-term prognosis in patients with acute perforating artery cerebral infarction(APACI).Methods Patients with APACI admitted to the Neurology Department of Anhui NO.2 Provincial People's Hospital from January 2019 to October 2024 were retrospectively enrolled in this study.General and clinical data,including age,gender,previous history(hypertension,diabetes,hyperlipidemia,coronary heart disease,atrial fibrillation),smoking history,drinking history,NIHSS scores at admission were collected.Fasting venous blood samples were collected from the patients within 24 h after admission to detect levels of neutrophils,lymphocytes,monocytes,platelets,blood urea nitrogen,and serum albumin.PIV(PIV=neutrophils × platelets × monocytes/lymphocytes)and BAR were calculated.The location of lesions and Fazekas classification of white matter lesions were evaluated using head MRI and MR angiography at admission.Collateral circulation status was assessed based on CT angiography upon admission.Disease progression was defined through comparing the NIHSS score at 72-hour after admission to the score at admission(an increase of 2 or more points in NIHSS score indicating disease progression).The patients were divided into a progression group and a non-progression group based on the increase in NIHSS score,as aforementioned.Patients follow-up was conducted through phone call or outpatient visits at 90 d after discharge.The modified Rankin scale(mRS)was used to evaluate the prognosis,with a mRS score of 0-2 indicates good prognosis,and a 3-6 indicates poor prognosis.Factors with statistically significant differences in univariate analysis were included in a multivariate Logistic regression analysis to explore the influencing factors of disease progression and poor prognosis in patients with APACI.The receiver operating characteristic(ROC)curve was used to evaluate the predictive value of each indicator for disease progression and poor prognosis in patients with APACI.Results A total of 165 patients with APACI were enrolled in this study,including 121 males and 44 females,aged 27-86 years,with an average of(61±11)years.Among all patients enrolled,56 patients were included in the progression group and 109 patients in the non-progression group,124 patients showed good prognosis and 41 patients had poor prognosis.No statistically significant differences were found in age,gender,smoking history,drinking history,hypertension,diabetes,hyperlipidemia,coronary heart disease,atrial fibrillation,lesion location,and Fazekas classification of white matter lesions between the progression group and the non-progression group(all P＞0.05).While the NIHSS score at admission,proportion of poor collateral circulation,PIV and BAR in the progression group were significantly higher than those in the non-progression group(all P＜0.05).Multivariate Logistic regression analysis showed that high NIHSS score at admission(OR,1.177,95％CI 1.001-1.384,P=0.049),poor collateral circulation(OR,3.107,95％CI 1.216-7.939,P=0.018),high PIV(OR,1.006,95％CI 1.003-1.009,P=0.001),and high BAR(OR,1.610 × 109,95％CI 5.769 × 104-4.494 × 1013,P＜0.01)were independent risk factors of disease progression in patients with APACI.ROC curve analysis results showed that the area under the curve(AUC)of combination of PIV,BAR,collateral circulation and NIHSS score at admission for predicting disease progression in patients with APACI was 0.914(95％ CI0.861-0.952,P＜0.01),which was greater than that of each indicator(all P＜0.05).No statistically significant differences were found in smoking,drinking,hypertension,hyperlipidemia,coronary heart disease,atrial fibrillation,lesion location,and BAR between the poor prognosis and the good prognosis group(all P＞0.05).Compared with the good prognosis group,the poor prognosis group had significantly older age and higher proportion of patients with diabetes,NIHSS score at admission,proportion of patients with poor collateral circulation,and PIV(all P＜0.05).Moreover,the proportion of men in the poor prognosis group was lower than that in the good prognosis group(P=0.039).There was a statistically significant difference between the good prognosis group and the poor prognosis group in the Fazekas classification of white matter lesions(P＜0.01).Multivariate Logistic regression analysis showed that high NIHSS score at admission(OR,1.345,95％CI 1.081-1.674,P=0.008),poor collateral circulation(OR,3.903,95％CI 1.061-14.355,P=0.040),and high PIV(OR,1.011,95％CI 1.005-1.017,P＜0.01)were independent risk factors of poor prognosis in patients with APACI.The AUC for predicting poor prognosis in patients with APACI through combining PIV,collateral circulation and NIHSS score at admission was 0.911(95％CI 0.857-0.950,P＜0.01),which is greater than using poor collateral circulation or NIHSS score at admission alone(both P＜0.05).However,there was no statistically significant difference in AUC between the PIV,collateral circulation and NIHSS score combined predictive model and the PIV(alone)predictive model(P＞0.05).Conclusions High PIV,high BAR,poor collateral circulation,and high NIHSS score at admission were independent risk factors of disease progression in patients with APACI.Combination of these four indices demonstrates relatively high predictive value for disease progression.In addition,high PIV,poor collateral circulation,and high NIHSS score at admission are independent risk factors of poor prognosis in patients with APACI.Joint detection of the three indices may assist in short-term prognosis evaluation of patients with APACI.

model(P＞0.05).Conclusions High PIV,high BAR,poor collateral circulation,and high NIHSS score at admission were independent risk factors of disease progression in patients with APACI.Combination of these four indices demonstrates relatively high predictive value for disease progression.In addition,high PIV,poor collateral circulation,and high NIHSS score at admission are independent risk factors of poor prognosis in patients with APACI.Joint detection of the three indices may assist in short-term prognosis evaluation of patients with APACI.
