Objective:To investigate disease characteristics of patients with psoriatic arthritis (PsA) based on the PsA cohort in West China Hospital, so as to provide a reference for clinicians in its diagnosis, treatment, and evaluation strategy formulation.Methods:A cross-sectional study was carried out, and a descriptive analysis was conducted on clinical data from PsA patients who were treated at the Department of Dermatology, West China Hospital, Sichuan University between April 2, 2020, and January 21, 2025. Demographic characteristics, clinical manifestations, laboratory and imaging findings, and treatment modalities were analyzed.Results:A total of 530 PsA patients were included, of whom 332 (62.6%) were males and 198 (37.4%) were females, with ages of 44.1 ± 12.4 years. Skin lesions preceded joint symptoms in 452 patients (85.3%), with time intervals ( M [ Q1, Q3]) of 8.0 (3.0, 15.0) years. Overweight or obesity was observed in 319 patients (60.2%), and 188 (35.5%) had comorbid fatty liver. Peripheral joint involvement was common (485 cases, 91.5%), with the proximal interphalangeal joints being most frequently affected by tenderness (172 cases, 35.5%) and swelling (119 cases, 24.5%) ; the number of enthesitis cases identified by ultrasonography (116 cases, 23.9%) was significantly higher than that by clinical examination (82 cases, 15.5%) ; axial joint involvement was observed in 258 patients (48.7%), with the sacroiliac joints most commonly affected (201 cases, 77.9%). Regarding treatment, conventional systemic drugs were predominant in the treatment of psoriasis prior to the diagnosis of PsA; after the diagnosis of PsA, the number of patients receiving targeted therapies increased to 334 (63.0%), with interleukin-17 inhibitors being the most common (140 cases, 26.4%), followed by tumor necrosis factor-α inhibitors (106 cases, 20.0%) and Janus kinase inhibitors (39 cases, 7.4%) . Conclusions:PsA predominantly affects males over 40 years old and is characterized by preceding skin lesions, delayed diagnosis, and multiple comorbidities. High-frequency ultrasound has advantages in the early detection of peripheral enthesitis. Further attention is needed for managing comorbidities such as fatty liver and obesity-related metabolic conditions.

Objective:To explore the clinical efficacy, safety and possible neuroimaging mechanism of deep transcranial magnetic stimulation (dTMS) and repetitive transcranial magnetic stimulation (rTMS) in the treatment of refractory migraine.Methods:Thirty patients with refractory migraine were selected from the Department of Neurology, Affiliated Hospital of North Sichuan Medical College from October 2022 to August 2023. The patients were randomly divided into dTMS group ( n=10), rTMS group ( n=10) and sham stimulation group ( n=10). The dTMS group was treated with H7 coil and the rTMS group with "8" coil, and the sham stimulation group was treated with sham stimulation rTMS with the frequency of 10 Hz. The stimulation site was the contralateral primary motor cortex (M1) of headache, which was treated for 2 weeks (3 600 pulses per time, 5 times per week, 10 times in total). Visual Analogue Scale (VAS) and Headache Impact Test-6 (HIT-6) evaluations were performed before treatment, on the first day after treatment, and 1, 3 and 6 months after treatment. The resting-state functional magnetic resonance images of the 3 groups of patients before and after treatment were collected and analyzed by MATLAB2018b, SPM12 and RESTPLUS softwares, and the brain regions with different regional homogeneity (ReHo) before and after treatment were obtained. The general clinical data and scale scoring data were analyzed and processed by SPSS 26.0 version software. Results:There were significant differences in VAS scores among the dTMS group (before treatment 6.70±0.68, the first day after treatment 5.60±0.70, 1 month after treatment 5.00±0.82, 3 months after treatment 3.50±0.85, 6 months after treatment 3.90±1.45), the rTMS group (before treatment 6.90±0.74, the first day after treatment 5.90±0.74, 1 month after treatment 5.30±0.82, 3 months after treatment 5.30±0.82, 6 months after treatment 6.80±0.63) and the sham stimulation group (before treatment 6.60±0.97, the first day after treatment 6.70±0.95, 1 month after treatment 6.90±1.10, 3 months after treatment 6.70±0.68, 6 months after treatment 7.10±0.88; F=16.054, P<0.001), VAS scores among different time points ( F=34.292, P<0.001), and the interaction between groups and time ( F=24.136, P<0.001). Compared with those before treatment, VAS scores in the dTMS group and the rTMS group decreased on the first day after treatment, 1 month and 3 months after treatment (all P<0.05); VAS scores decreased in the dTMS group 6 months after treatment ( P<0.05). Compared with the sham stimulation group, the VAS scores of the dTMS group were lower at the same time points after treatment (all P<0.05), and the VAS scores of the rTMS group were lower on the first day after treatment, 1 month and 3 months after treatment (all P<0.05). Compared with the rTMS group, VAS scores were lower at 3 and 6 months after dTMS treatment (both P<0.05). There were significant differences in HIT-6 scores among groups ( F=13.173, P<0.001), HIT-6 scores among different time points ( F=60.788, P<0.001), and interaction between groups and time ( F=35.576, P<0.001). Compared with those before treatment, the HIT-6 scores in the dTMS group decreased on the first day after treatment ( P<0.05); the HIT-6 scores in the dTMS group and the rTMS group decreased 1 month and 3 months after treatment (both P<0.05); the HIT-6 scores decreased in the dTMS group 6 months after treatment ( P<0.05). Compared with the sham stimulation group, the HIT-6 scores were lower in the dTMS group at the same time points after treatment (all P<0.05), and the HIT-6 scores were lower in the rTMS group at 1 and 3 months after treatment (both P<0.05). Compared with the rTMS group, HIT-6 scores were lower at 3 and 6 months after dTMS treatment (both P<0.05). Analysis of ReHo results: compared with those before treatment, the ReHo values of the right cerebellar angle area 1 increased in the dTMS group and the sham stimulation group, decreased in the rTMS group. The ReHo values of the right middle occipital gyrus, left dorsolateral superior frontal gyrus and right cerebellar area 8 increased in the dTMS group, but decreased in the rTMS group and the sham stimulation group. The ReHo values of the left precentral gyrus and left superior temporal gyrus decreased in the dTMS group, while those in the rTMS group and the sham stimulation group increased. There were no obvious adverse reactions in the 3 groups during the treatment and follow-up period. Conclusions:dTMS and rTMS may help to improve the headache degree and quality of life of patients with refractory migraine, and they are safe, which may be related to the changes of brain network in the right cerebellar angle area 1, right middle occipital gyrus, left dorsolateral superior frontal gyrus, left precentral gyrus, left superior temporal gyrus and right cerebellar area 8.

This paper analyzes the characteristics of highly cited papers published in Chinese Clinical Pharmacology and Therapeutics in the past ten years,in order to explore the influence and re-search value of these papers.Highly cited papers are an important index to evaluate the scientific re-search level of scholars and research institutions,so this study focuses on the characteristics of their number,citation frequency,number of co-authors and regional distribution.The paper uses bibliomet-rics to analyze the publication trend and citations of highly cited papers.The results show that during the observation period,the number of highly cited papers decreases year by year,and there is a signifi-cant correlation between cited frequency and publi-cation time.In addition,the number of co-authors presents a normal distribution,among which the number of co-authors is the largest,indicating that moderate cooperation has a positive effect on the influence of papers.From the perspective of geo-graphical distribution,the author group of the mag-azine is relatively dispersed,covering many regions of the country,among which Anhui,Hunan and Zhejiang have become the main sources of high-quality manuscripts.The finding reflects the maga-zine's wide reach across the country.The results of this study provide empirical support for under-standing the characteristics of highly cited papers and emphasize the importance of research collabo-ration and geographical factors in research publica-tion.Through the analysis of highly cited papers,this paper provides references for subsequent re-searchers in selecting research topics and coopera-tion methods,and also provides beneficial sugges-tions for improving the research level and influence of clinical pharmacology in China.

ObjectiveThe glycosidic linkage structural characteristics of polysaccharides from Pinelliae Rhizoma（PR） and its processed products were analyzed by sugar spectrum， high performance thin layer chromatography（HPTLC）， fluorescence-assisted carbohydrate gel electrophoresis（PACE） based on partial acid hydrolysis and specific glycosidase hydrolysis， and the antioxidant activities of polysaccharides before and after hydrolysis（enzymolysis） were compared. MethodPolysaccharides from PR and its processed products were extracted by ultrasound extraction， starch was hydrolyzed by α-amylase， and small molecules below 3 kDa were removed by ultrafiltration. The purified polysaccharides were prepared by hydrolysis of acid and five different specific glycosidases， and the hydrolysates were analyzed by HPTLC and PACE. The antioxidant capacity of polysaccharides was analyzed by 2，2′-azino-bis（3-ethylbenzthiazoline-6-sulfonic acid）（ABTS） and 2，2-diphenyl-1-picrylhydrazyl（DPPH） free radical scavenging experiment before and after different hydrolysis. ResultThrough HPTLC and PACE analysis， it was found that polysaccharides from PR and its processed products could be hydrolyzed by β-galactosidase， β-mannase， cellulase and pectinase， but hardly hydrolyzed by glucanase， indicating that the polysaccharides contained β-galactopyranoside bond， β-1，4-mannoside bond， β-1，4-glucoside bond and α-1，4-galacturonic acid glycosidic bond. In vitro antioxidant experiments showed that the ABTS radical scavenging capacity of the polysaccharides from PR and its processed products was weakened after acid hydrolysis and pectinase enzymatic hydrolysis， while the ABTS radical scavenging capacity was enhanced after enzymatic hydrolysis with cellulase， β-galactosidase， and β-mannase. And after different hydrolysis， the DPPH free radical scavenging capacity of polysaccharides from PR and its processed products was all significantly enhanced. ConclusionThe glycosidic linkage structural characteristics of polysaccharides from PR and its processed products was analyzed by sugar spectrum in this paper， and the relationship between glycosidic bond types and their antioxidant activity was clarified through in vitro antioxidant experiments， which is beneficial for further elucidating the material basis of the related efficacy of PR and its processed products， and providing new ideas and methods for analyzing the structural characteristics of polysaccharides in Chinese medicines.

ObjectiveTo explore the prevalence difference between northwest dryness syndrome and blood stasis syndrome of coronary heart disease （CAD） and their correlations with major adverse cardiovascular events （MACE）. MethodsThe medical records including general information and risk factors for vascular diseases （gender， age， smoking history， diabetes history， hypertension history， chronic kidney disease history and body mass index）， laboratory indicators （fasting blood glucose， triglyceride， high density lipoprotein cholesterol， etc.） of 499 CAD patients in the Department of Cardiology of the Affiliated Hospital of Traditional Chinese Medicine of Xinjiang Medical University from November 1st， 2015 to September 30th，2020 were collected， and whether they suffered from northwest dryness syndrome or blood stasis syndrome was judged. The incidence of MACE was followed up for one year. The differences of cardiovascular risk factors between the northwest dryness syndrome and blood stasis syndrome of CAD were compared， and the correlation with MACE was analyzed. ResultsAmong the 499 CAD patients， there were 128 cases （25.65%） of simple blood stasis syndrome， 33 cases （6.61%） of simple northwest dryness syndrome， 209 cases （41.88%） of northwest dryness syndrome plus blood stasis syndrome， and 129 （25.85%） cases of not blood statis syndrom either northwest dryness syndrome. Univariate regression analysis showed that smoking history， diabetes history， fasting blood glucose abnormality， triglyceride abnormality， and high density lipoprotein cholesterol abnormality were positively correlated with northwest dryness syndrome in CAD patients （OR＞1， P＜0.05）， while smoking history， abnormal triglyceride and abnormal high density lipoprotein cholesterol were positively correlated with blood stasis syndrome in CAD patients （OR＞1， P＜0.05）. Multivariate regression analysis showed that the history of diabetes， abnormal triglyceride and abnormal high density lipoprotein cholesterol were positively correlated with northwest dryness syndrome of CAD （P＜0.05）. Smoking history， abnormal triglycerides and abnormal high density lipoprotein cholesterol were positively correlated with blood stasis syndrome （P＜0.05）. Association rule analysis showed that the confidence of CAD patients with northwest dryness syndrome complicated with blood stasis syndrome was 86.36%， and that of patients with blood stasis syndrome complicated with northwest dryness syndrome was 62.02%. Among the 499 patients， 96 had MACE in one year， accounting for 19.24% of the total. Logistics regression analysis showed that the correlation with incidence of MACE in CAD patients within one year from strong to weak was northwest dryness syndrome plus blood stasis syndrome ［OR = 5.113， 95%CI （3.118， 8.387）， P＜0.001）］， blood stasis syndrome［OR = 4.630， 95%CI （2.394， 8.955）， P＜0.001］， northwest dryness syndrome ［OR = 4.395， 95%CI （2.642， 7.309）， P＜0.001］. ConclusionBlood stasis syndrome is the main syndrome type of CAD in Xinjiang Uygur Autonomous Region. CAD patients with northwest dryness syndrome are more likely to have blood stasis syndrome， and most suffer from both northwest dryness syndrome and blood stasis syndrome simultaneously. There is the strongest correlation between northwest dryness syndrome plus blood stasis syndrome and 1-year occurrence of MACE in CAD.

Objective:To compare the differences of brain activation in patients with neuromyelitis optica spectrum disorders (NMOSD) and multiple sclerosis (MS) under contact heat stimulation (CHS), and to explore the characteristics of pain-related brain networks in NMOSD and MS patients.Methods:Fourteen NMOSD patients (NMOSD group) and 12 MS patients (MS group) admitted to Affiliated Hospital of North Sichuan Medical College from September 2022 to December 2022 who met the diagnostic criteria were collected. Twelve healthy individuals (HC group) matched with gender and age were recruited during the same period. Visual Analogue Scale (VAS) score was used to evaluate the pain of the subjects, CHS painful stimuli were given, and task-state functional magnetic resonance imaging (fMRI) scans were performed at the same time, and the differences in brain activation among the 3 groups were analyzed and compared.Results:(1) Compared with the HC group, the NMOSD group had a stronger activation degree than the HC group in the brain regions including the cortex around the left distance fissure, bilateral medial superior frontal gyrus; the activation degree of the NMOSD group was weaker than that of the HC group in the brain areas including the left medial and paracingulate gyrus, right superior parietal gyrus, left postcentral gyrus, and right supplementary motor area (all P<0.05). (2) Compared with the HC group, the brain regions whose activation degree was weaker in the MS group included the left caudate nucleus, left medial and paracingulate gyrus, left paracentral lobule, right superior parietal gyrus, left postcentral gyrus, left precuneus, right supplementary motor area, right superior temporal gyrus and right thalamus, and there was no brain area in the MS group whose activation degree was stronger than that of the HC group (all P<0.05). (3) Compared with the MS group, the brain regions with stronger activation degree in the NMOSD group included the left perifissure cortex and right thalamus, but no brain regions with weaker activation degree were found in the NMOSD group (all P<0.05). (4) There was a correlation between somatic pain VAS scores and activation of the medial superior frontal gyrus in the NMOSD group ( r=0.66, P<0.05). Conclusions:The results of CHS-fMRI in the NMOSD group, MS group and HC group showed that multiple brain regions were activated, indicating that multiple brain regions were involved in the generation and processing of pain, and there was a pain-related brain network. Pain-related brain networks were altered in NMOSD patients and MS patients, and there were differences in pain-related brain networks between the two diseases.

Aim To investigate the effect of Ajuga decumbens(HBG), Poria cocos(FL) and their combination on the metastasis of invasive breast cancer cells and the related mechanisms.Methods We conducted several assays including cell adhesion assay, scratch assay and transwell invasion assay.Western blot analysis was employed to detect the expression of associated proteins of EMT and MAPK signaling pathway.Results FL,HBG and their combination could significantly inhibit the adhesion, migration and invasion of MDA-MB-231 and SK-BR-3 cells.HBG and FL had markedly synergistic effect, and the best compatibility ratio was 10 ∶1.HBG, FL and their combination could reverse EMT of breast cancer cells, which increased the levels of epithelial biomarkers, such as β-catenin, E-cadherin and ZO-1, and reduced the levels of mesenchymal biomarkers, such as vimentin.Moreover, treatment of the cells with HBG, FL and their combination resulted in marked inhibition of phosphorylation of ERK1/2, JNK and p38.Conclusions The combination of HBG and FL have the ability to inhibit breast cancer cell invasion by targeting the expression of MAPK pathway as well as suppressing the epithelial-to-mesenchymal transition.
