OBJECTIVE To prepare the β -cyclodextrin （ β -CD） inclusion complex with volatile oil from Qianghuo qushi qingwen granules， and to characterize and quantitatively analyze the inclusion complex. METHODS The comprehensive scores calculated by inclusion rate and inclusion compound yield were used as indicators for screening the inclusion method. The single-factor experiments and Box-Behnken response surface experiments were used to op timize the inclusion conditions， with the above comprehensive score as response value， and taking the ratio of β -CD to volatile oil， inclusion temperature and inclusion time as indexes. The volatile oil inclusion complex of Qianghuo qushi qingwen granules was prepared according to the determined optimal process， followed by validation. Ultraviolet （UV）-visible spectroscopy， thin-layer chromatography （TLC）， and microscopic imaging were also performed. Ultra-high performance liquid chromatography was used to determine the contents of perillaldehyde， pogostone and atractylodin. RESULTS The saturation aqueous solution method was adopted. The optimal inclusion process conditions were as follows： the ratio of β -CD to volatile oil was 7.5∶1， the inclusion temperature was 40 ℃， and the inclusion time was 2.2 h. In three verification experiments， the average inclusion rate was 72.32%， the average yield of inclusion compound was 74.45%， the average comprehensive score was 72.96 points， and the relative error with the predicted value （74.15 points） of the model was 1.61%. UV-visible spectroscopy， TLC and microscopic imaging showed that β -CD and volatile oil successfully formed a new inclusion complex. The average contents of perillaldehyde， pogostone and atractylodin were 4.498 2， 0.814 9， 0.905 7 mg/g， respectively， with RSDs of 0.31%， 0.56% and 0.63% （ n ＝3）. CONCLUSIONS A stable and feasible preparation process of the volatile oil inclusion complex of Qianghuo qushi qingwen granules is successfully established.

ObjectiveTo evaluate the efficacy and safety of Janus kinase （JAK） inhibitors combined with Chinese herbal medicine （CHM） in treating rheumatoid arthritis （RA）. MethodsClinical data from 169 RA patients were retrospectively collected. Among them， 71 cases received JAK inhibitors as the control group， while 98 cases received JAK inhibitors plus CHM as the observation group， both treated for 24 weeks. The rheumatoid factor （RF）， cyclic citic peptide antibody （anti-CCP）， erythrocyte sedimentation rate （ESR）， C-reactive protein （CRP）， and white blood cell count （WBC） were recorded before and after treatment. Databases including CNKI， Wanfang， VIP， PubMed and Web of Science were searched from inception till August 31st， 2025 for randomized controlled trials （RCTs） on the combined use of JAK inhibitors and CHM for RA. The methodological quality of the included studies was evaluated using the risk of bias assessment tool. Meta-analyses were performed for RF， anti-CCP， ESR， CRP， 28-joint disease activity score （DAS28）， overall clinical effective rate， and incidence of adverse events. Sensitivity analysis were also performed. ResultsThe retrospective study demonstrated that after treatment， ESR， CRP， and anti-CCP levels decreased in the observation group， while ESR and CRP levels decreased in the control group （P＜0.05）. Moreover， ESR and RF levels in the observation group were lower than those in the control group （P＜0.05）. A total of 9 RCTs involving 770 patients were included in the meta-analysis. The results indicated that the JAK inhibitors plus CHM group was superior to the JAK inhibitors group in reducing RF （MD=-8.97， 95%CI -15.01 to -2.94， P=0.004）， CRP （MD=-3.34， 95%CI -3.82 to -2.86， P＜0.001）， ESR （MD=-5.33， 95%CI -7.98 to -2.69， P＜0.001）， and DAS28 score （MD=-0.54， 95%CI -0.74 to -0.34， P＜0.001）， as well as in improving the overall clinical effective rate （OR=4.53， 95%CI 2.55 to 8.03， P＜0.001）. No statistically significant differences were observed between groups in anti-CCP levels （SMD=-2.08， 95%CI -4.41 to 0.24， P=0.080） or incidence of adverse events （OR=0.93， 95%CI 0.55 to 1.57， P=0.790）. ConclusionThe combination of JAK inhibitors and CHM demonstrates remarkable efficacy in treating RA， contributing to improved disease activity and reduced inflammatory markers with a favorable safety profile.

Objective:To investigate the role and molecular mechanisms of signal transducer and activator of tran-scription 3(STAT3)in the paraventricular nucleus(PVN)of the hypothalamus in regulating body weight and energy metabolism in mice.Methods:AAV2/9-hSyn-Cre-EGFP virus was stereotactically injected into the PVN of STAT3Flox/Flox mice to conditionally knock out(CKO)STAT3 in the PVN.STAT3 expression was verified via immunoflu-orescence staining and Western blot.Body weight and temperature were monitored,glucose tolerance was assessed using glucose tolerance tests in mice,and morphological changes in the liver,interscapular brown adipose tissue(IBAT),in-guinal white adipose tissue(IWAT),and quadriceps muscle were evaluated via hematoxylin-eosin(HE)staining.RT-qPCR was used to measure mRNA levels of platelet-derived growth factor receptor α(PDGFRα),peroxisome prolifera-tor-activated receptor γ(PPARγ),hormone-sensitive lipase(HSL),and adipose triglyceride lipase(ATGL)in these tissues.Results:STAT3 protein expression in the PVN of CKO mice was significantly reduced,and the number of STAT3-positive neurons was also decreased.Compared to wild-type(WT)mice,CKO mice exhibited increased body weight,impaired thermogenesis in IBAT,and reduced glucose tolerance.HE staining revealed lipid droplet accumula-tion in hepatocytes of the liver,enlarged adipocytes with hypertrophic lipid droplets and leukocyte infiltration in adipose tissues,and intermuscular fat deposition in the quadriceps muscle.RT-qPCR analysis showed decreased mRNA levels of PDGFRα,HSL,and ATGL in the liver;upregulated PPARγ mRNA but downregulated HSL and ATGL mRNA in IBAT and IWAT;and reduced PPARγ and HSL mRNA levels in the quadriceps muscle of CKO mice.Conclusion:The STAT3 signaling pathway in the PVN is critical for maintaining systemic energy balance and serves as a key node in met-abolic regulation.

Objectives:To explore the relationship between epicardial adipose tissue(EAT),left atrium and left atrial appendage(LAA)structures and LAA thrombosis in patients with non-valvular atrial fibrillation.Methods:Clinical data from non-valvular atrial fibrillation patients who underwent cardiac computed tomography angiography(CTA)and transesophageal echocardiography(TEE)at the Second Hospital of Hebei Medical University between November 2019 and October 2024,were retrospectively collected.Twenty-eight patients diagnosed with LAA thrombus by both CTA and TEE were enrolled as the LAA thrombus group(20 males,8 females,average age[65±9]years).Using an individual matching method,56 non-valvular atrial fibrillation patients without LAA thrombus,matched for gender and age(±3 years),were sequentially enrolled at a ratio of 1:2 as the no-thrombus group(40 males,16 females,average age[65±8]years).CTA was used to measure the epicardial adipose tissue volume(EATV),left atrial epicardial adipose tissue volume(LA-EATV),and structural parameters of the left atrium and LAA in both groups.The correlation between EAT,structural parameters of the left atrium/LAA and LAA thrombosis was evaluated.Results:In the LAA thrombus group,the proportions of patients with persistent atrial fibrillation and atrial fibrillation rhythm were significantly higher than in the no-thrombus group(both P<0.001).There were no statistically significant differences between the two groups in terms of age,gender composition,body mass index,duration of atrial fibrillation,and the proportions of patients with hypertension,diabetes,dyslipidemia,coronary heart disease,ischemic stroke,heart failure,vascular disease,and CHA2DS2-VASc scores(all P>0.05).Compared to the no-thrombus group,the EATV,LA-EATV,left atrial volume(LAV),LAA volume(LAAV),and LAA orifice area were significantly higher in the LAA thrombus group(all P<0.05).There was no significant difference between the two groups in the LAA depth(P=0.076).Conditional logistic regression analysis showed that LA-EATV(OR=1.092,95%CI:1.004-1.187,P=0.040)and LAV(OR=1.022,95%CI:1.003-1.041,P=0.025)were independent predictors of LAA thrombosis in non-valvular atrial fibrillation patients.The LA-EATV threshold for predicting LAA thrombosis was 27.16 cm3,with an area under the receiver operating characteristic curve(AUC)of 0.843(sensitivity 85.7%,specificity 76.8%);the LAV predictive threshold was 118.45 ml(AUC=0.853,sensitivity 82.1%,specificity 80.4%).Conclusions:LA-EATV and LAV measured by cardiac CTA are independent predictors of LAA thrombosis in patients with non-valvular atrial fibrillation.

Objectives:This study aimed to investigate the impact of quantitative flow ratio(QFR)-guided revascularization on outcome of elderly patients with coronary artery disease(CAD)undergoing valve surgery.Methods:We retrospectively analyzed 750 consecutive patients with angiographically confirmed CAD(≥50%stenosis)who underwent valve surgery at Zhongshan Hospital,Fudan University,between January 2016 and December 2021.According to the patients'ages,they were divided into the younger group(age<70 years old,n=532)and the elderly group(age≥70 years old,n=218).Revascularization strategies were evaluated using anatomical(angiography-based)and functional(QFR-based)criteria.Anatomical complete revascularization(CR)was defined as bypass grafting for all lesions with≥70%diameter stenosis in major coronary arteries or≥50%stenosis in the left main coronary artery.Functional CR referred bypass grafting for all lesions with QFR≤0.80.Incomplete revascularization(ICR)was defined as failure to meet CR criteria.According to the anatomical and functional definitions,the younger group and the elderly group were further divided into the incomplete revascularization subgroup and the complete revascularization subgroup respectively.Major adverse cardiovascular events(MACE),including death,myocardial infarction,repeat revascularization,and stroke,were assessed as the composite endpoint.Results:Over a follow-up of(3.7±1.8)years,the overall MACE rate was 13.3%.The younger group exhibited significantly lower MACE rates than the elderly group(10.7%vs.19.7%,P=0.001).In the younger group,anatomical ICR did not increase MACE risk(HR=1.46,95%CI:0.81-2.62,P=0.164),whereas functional ICR significantly increased MACE risk(HR=2.27,95%CI:1.24-4.15,P=0.001).In the elderly group,neither anatomical ICR(HR=1.22,95%CI:0.62-2.41,P=0.540)nor functional ICR(HR=1.52,95%CI:0.78-2.96,P=0.172)was associated with increased MACE risk.Conclusions:In patients undergoing valve surgery with CAD,functional ICR correlated with adverse outcomes in the younger group,whereas neither anatomical nor functional ICR significantly affected prognosis in elderly patients.These findings suggest that a moderately conservative revascularization strategy may be more appropriate for elderly populations.

Objective To construct an intelligent recognition,prevention,and control system for infectious disea-ses and multidrug-resistant organism infections,aiming at improving the efficacy of full-process management,and to evaluate its application effects.Methods Based on personalized logic parsing rules that accurately reflect the infec-tion status and transmission risks in real-time,an intelligent recognition,prevention,and control system with func-tions of automatic recognition,dynamic labeling,real-time sharing,early warning,and visual guidance was estab-lished.Patients undergoing invasive diagnostic and therapeutic procedures in two departments of a tertiary first-class hospital from October 2023 to May 2024 were selected as the research subjects.The differences in recognition,pre-vention,and control efficacy before and after the application of the system were compared using a self-controlled method,with traditional manual management as the control group and intelligent system management as the experi-mental group.Results A total of 2 146 patients were included in the analysis.The recognition,prevention,and control rate and the accuracy rate of recognizing infected individuals using the intelligent system were enhanced sig-nificantly compared with those using manual mode(improved from 5.3％and 72.4％to 100％,respectively),with statistical significance(both P＜0.001).The median early warning time for infection information reached 85.20 days,with 100％early warning achieved.The average time spent by medical staff on infection information recogni-tion and management was reduced by 4.71 hours per day.Conclusion The intelligent system constructed in this study significantly improves the effectiveness of full-process management in recognition,prevention,and control of infectious diseases and multidrug-resistant organism infection,effectively reduces the risk of cross-infection,and en-hances the efficiency of diagnostic and therapeutic services.

Objective:To explore the effect of Bian-stone warming and ironing therapy on gastrointestinal blood flow in patients with severe cerebrovascular disease undergoing therapeutic hypothermia.Methods:From January 2023 to October 2024, 92 patients with severe cerebrovascular disease in the Neurosurgical Intensive Care Unit of Xuanwu Hospital of Capital Medical University were selected for the study using convenience sampling method. The patients were divided into a control group and an experimental group of 46 cases each according to the randomized numerical table method. Control group was given routine nursing, and experimental group carried out Bian-stone warming and ironing therapy on the basis of control group. Peak systolic velocity (PSV), end-diastolic velocity (EDV), and time-averaged mean velocity (TAMV) of the superior mesenteric artery of the two groups of patients were monitored before and after five days of intervention, respectively, and the situation of gastric retention and bowel sounds were recorded and compared between the groups.Results:PSV was higher in experimental group than in control group after intervention, and the difference was statistically significant ( P<0.05). The difference in EDV between the two groups was not statistically significant ( P>0.05). TAMV of experimental group was higher than that of control group after intervention, and the difference in TAVM before and after intervention of experimental group was smaller than that of control group, and the differences were all statistically significant ( P<0.05). The number of cases of gastric retention and weakened or disappeared bowel sounds in experimental group was less than that in control group after intervention, and the differences were all statistically significant ( P<0.05) . Conclusions:Bian-stone warming and ironing therapy improves gastrointestinal blood flow rate and reduces feeding intolerance in patients with severe cerebrovascular disease undergoing therapeutic hypothermia.

ObjectiveBased on the theory of "gut-prostate" axis， this study explored the effects and mechanisms of Zishen Tongguan formula and Cinnamomi Cortex in the formula in treating rats with chronic non-bacterial prostatitis（CNP） by detecting the levels of inflammatory factors， and the composition and structure of intestinal flora in CNP rats. MethodsEight out of 42 SD rats were randomly selected as the normal group， and the remaining rats were injected with carrageenan to prepare the CNP model. After successful modeling， 32 rats were randomly divided into the model group， Ningmitai capsule group（0.50 g·kg^-1）， Zishen Tongguan formula group（2.00 g·kg^-1）， and the Phellodendri Chinensis Cortex-Anemarrhenae Rhizoma pair group（PCC-AR group， 2.00 g·kg^-1）， with 8 rats in each group. The administered groups were given the corresponding medicinal solution by gavage， and the normal and model groups were intragastrically administered with an equal volume of normal saline， once a day for 14 consecutive days. The prostate tissues of rats were collected and subjected to hematoxylin-eosin（HE） staining and Masson staining to observe the pathological changes of the tissues in each group. Enzyme-linked immunosorbent assay（ELISA） was used to detect the levels of related inflammatory factors in rat serum， and 16S rDNA sequencing was used to analyze the abundance and diversity changes of gut microbiota before and after administration， and species difference analysis was performed. ResultsAll the administered groups could alleviate the inflammatory symptoms of CNP rats， increase the expression levels of anti-inflammatory factors and decrease the expression levels of pro-inflammatory factors， with the most sIgnificant effect observed in the Zishen Tongguan formula group. Compared with the normal group， the expression levels of interleukin（IL）-8， hypersensitive C-reactive protein（hs-CRP）， immunoglobulin（Ig）M， secretory IgA （sIgA）， and inducible nitric oxide synthase（iNOS） were sIgnificantly increased in the model group（P<0.01）. Compared with the model group， the expression levels of the above inflammatory factors in all administered groups were significantly reduced（P<0.01）. When compared with the PCC-AR group， the Zishen Tongguan formula group showed a significant decrease in transforming growth factor（TGF）-β₁ expression level（P<0.05） and a significant increase in IgM expression level（P<0.01）. The results of gut microbiota analysis showed that， compared with the PCC-AR group， at the order level， the Zishen Tongguan formula group significantly reduced the relative abundance of conditional pathogens such as Bacteroidales， Acidaminococcales， Rhodospirillales， Clostridiales， and Elusimicrobiales（P<0.01）. And at the genus level， the Zishen Tongguan formula group significantly decreased the relative abundance of pathogenic microbiota such as Lachnospira and Bacteroides（P<0.01） and significantly increased the relative abundances of beneficial microbiota such as Ruminococcus and Lactobacillus（P<0.01）. ConclusionZishen Tongguan formula can reduce the level of harmful intestinal bacteria， increase the level of beneficial intestinal bacteria， down-regulate the expression of serum inflammatory factors， and the small amount of Cinnamomi Cortex in the formula may play a key role in the treatment of CNP with this formula.
