OBJECTIVE To investigate the current status of pharmaceutical care in medical institutions in China， and provide experience and suggestions for better development of pharmaceutical care. METHODS Questionnaire survey was used to investigate the development of pharmaceutical care in medical institutions in 31 provinces （autonomous regions and municipalities directly） in March 2023， and descriptive analysis and binary logistic regression analysis on the influencing factors of pharmaceutical care were conducted. RESULTS A total of 1 368 questionnaires were sent out， and 1 304 valid questionnaires were collected with the effective recovery rate of 95.32%. Pharmaceutical care was carried out in 671 medical institutions （51.46%）， and the rates of pharmaceutical care in tertiary， secondary， primary and other medical institutions were 74.79%， 27.97% and 7.35%， respectively. The average number of patients receiving pharmaceutical care was 2 638.96 per year， and there were 8.33 pharmacists in each medical institution to carry out pharmaceutical care， among which 93.68% were clinical pharmacists. The main departments covered by pharmaceutical care services included respiratory and critical care medicine， cardiology， intensive care unit， endocrinology， oncology， gastroenterology， obstetrics and gynecology and other departments. There were only 48 medical institutions （7.15%） with additional compensation for pharmaceutical care services. The main experiences of developing pharmaceutical care were to pay attention to talent cultivation and discipline construction， but the main difficulties were serious shortage of staff and qualified talents， low compensation level and low enthusiasm. Grade of medical institutions， the number of pharmacists engaged in clinical pharmacy， the number of qualified clinical pharmacists and the degree of information in the pharmacy department were the main influencing factors for carrying out pharmaceutical care （P＜0.05）. CONCLUSIONS In recent years， pharmaceutical care in Chinese medical institutions has made certain progress， while that of primary medical institutions， secondary medical institutions and other medical institutions should be improved. In the future， it is still necessary to further enhance the implementation of pharmaceutical care， promote personnel training， and attach importance to demonstrating the value of pharmaceutical care， thereby promoting the sustainable and high- quality development of pharmaceutical care.

BACKGROUND: G protein-coupled receptor kinase 2 (GRK2) could participate in the regulation of diverse cells via interacting with non-G-protein-coupled receptors. In the present work, we explored how paroxetine, a GRK2 inhibitor, modulates the differentiation and activation of immune cells in rheumatoid arthritis (RA). METHODS: The blood samples of healthy individuals and RA patients were collected between July 2021 and March 2022 from the First Affiliated Hospital of Anhui Medical University. C57BL/6 mice were used to induce the collagen-induced arthritis (CIA) model. Flow cytometry analysis was used to characterize the differentiation and function of dendritic cells (DCs)/T cells. Co-immunoprecipitation was used to explore the specific molecular mechanism. RESULTS: In patients with RA, high expression of GRK2 in peripheral blood lymphocytes, accompanied by the increases of phosphatidylinositol 3 kinase (PI3K), protein kinase B (AKT), and mammalian target of rapamycin (mTOR). In animal model, a decrease in regulatory T cells (T regs ), an increase in the cluster of differentiation 8 positive (CD8 + ) T cells, and maturation of DCs were observed. Paroxetine, when used in vitro and in CIA mice, restrained the maturation of DCs and the differentiation of CD8 + T cells, and induced the proportion of T regs . Paroxetine inhibited the secretion of pro-inflammatory cytokines, the expression of C-C motif chemokine receptor 7 in DCs and T cells. Simultaneously, paroxetine upregulated the expression of programmed death ligand 1, and anti-inflammatory cytokines. Additionally, paroxetine inhibited the PI3K-AKT-mTOR metabolic pathway in both DCs and T cells. This was associated with a reduction in mitochondrial membrane potential and changes in the utilization of glucose and lipids, particularly in DCs. Paroxetine reversed PI3K-AKT pathway activation induced by 740 Y-P (a PI3K agonist) through inhibiting the interaction between GRK2 and PI3K in DCs and T cells. CONCLUSION Paroxetine exerts an immunosuppressive effect by targeting GRK2, which subsequently inhibits the metabolism-related PI3K-AKT-mTOR pathway of DCs and T cells in RA.

Objective: To investigate the attention cognitive function and symptom correlations of school aged children with attention deficit hyperactivity disorder (ADHD)using event related potential (ERP) technology, so as to provide references for the early diagnosis of children with ADHD. Methods: A total of 52 school aged children diagnosed with ADHD at the outpatient department of the Third Affiliated Hospital of Zhengzhou University from September 2022 to September 2024 and 50 age /sex matched healthy controls were selected. The ERP experiment adopted the auditory Oddball task to conduct comparative analyses of the amplitude and latency of the mismatch negative(MMN) at the Fz, Cz, and Pz points of the scalp electrode and the P3a component respectively. The symptom assessment scales adopted the Swanson,Nolan,and Pelham-Ⅳ Rating Scale (SNAP-Ⅳ) and the Parent Symptom Questionnaire (PSQ), which were filled out by the parents. Spearman correlation analysis was used to analyze the correlation between ERP components and symptoms in schoolaged children with ADHD. Results: The latency of MMN components in the healthy control group on the Fz lead was (188.30±2.06)ms, and the amplitude was (-15.54±1.35)μV; the latency of the P3a component on the Pz lead was (312.82±7.80)ms, and the amplitude was (3.80±0.18)μV. The latency of MMN components in the ADHD group on the Fz lead was (188.94±1.39)ms, and the amplitude was (-14.78±1.40)μV; the latency of the P3a component on the Pz lead was (317.21±5.65)ms, and the amplitude was (3.70±0.13)μV. Compared with normal children, the MMN of children with ADHD had smaller amplitudes in the Fz and Cz leads, and the P3a had greater latency and smaller amplitudes in the Cz and Pz leads ( t =2.79,2.20；-2.04，-3.25；2.35,3.21， P <0.05). Correlation analysis showed that the latency of MMN in children with ADHD was positively correlated with the inattention score in the SNAP-Ⅳ( r =0.22), and the amplitude of MMN was negatively correlated with the inattention score in the SNAP-Ⅳ and the learning problem score in PSQ ( r = -0.26 , -0.34)( P <0.05). The latency of P3a was positively correlated with the scores of inattention in the SNAP-Ⅳ and the score of learning problems in the PSQ ( r =0.26 ,0.24); the amplitude of P3a was negatively correlated with the scores of attention deficit and hyperactivity/impulsivity in the SNAP-Ⅳ and the scores of learning problems and impulsivity/hyperactivity in the PSQ( r = -0.26 , -0.22, -0.25,-0.32)( P <0.05). Conclusions School aged ADHD children exhibit abnormal MMN/P3a components, indicating attention related cognitive dysfunction. Symptoms such as inattention, learning problems and hyperactivity/impulsivity in children with ADHD are related to abnormal components of MMN and P3a.

Objective: To investigate the clinical efficacy and safety of pudendal nerve modulation (PNM) in the treatment of female pudendal neuralgia (PN)，so as to promote the clinical application of this technique. Methods: A retrospective analysis was conducted on 20 female PN patients who failed conservative treatment at Gongli Hospital during Nov.2020 and Oct.2023.All patients underwent simultaneous PNM and sacral nerve modulation (SNM) with the assistance of 3D printing navigation.Dual-stage test electrodes for PNM and SNM were implanted，followed by alternate therapeutic trial for each modality.Secondary conversion rates and longitudinal outcomes，including visual analogue score (VAS)，patient health questionnaire-9 (PHQ-9)，and quality of life (QoL) scores were compared preoperatively，post-stage Ⅰ，and at 3，6，and 12 months post-stage Ⅱ. Results: All operations were successful.After the trial phase，the secondary conversion rate for PNM was significantly higher than that for SNM; 16 patients (16/20，80%) chose the second-phase PNM implantation surgery，3 (3/20，15%) chose second-phase SNM implantation，and 1 (1/20，5%) had electrodes removed due to ineffective results from both trials.Further assessment revealed that the improvements in VAS，PHQ-9，and QoL scores for PNM patients were significantly better than those for SNM patients after the first phase of surgery and at 3，6 and 12 months after the second-phase conversion (P<0.05).No complications such as electrode migration or infection were observed during the follow-up of 12-15 months. Conclusion: PNM provides more effective relief of pain symptoms and improvements in depressive states for female PN patients compared to SNM.With the assistance of 3D printing navigation，the operation is simple and safe，and offers stable therapeutic effects.It is worthy of clinical promotion and application.

Objective: To evaluate the effectiveness of "Internet plus" continuous intervention on psychological status and nursing satisfaction of patients with depression after hospital discharge, so as to provide the reference for reducing the recurrence risk of patients with depression and improving the quality of life. Methods: From January to December 2024, patients with mild to moderate depression who were hospitalized in a tertiary grade-a mental health specialized hospital in Wenzhou City and met the discharge criteria were selected as the research objects. The patients were divided into the control group and the intervention group according to a ratio of 1∶1 by the random number table method. Hamilton Depression Scale, Hamilton Anxiety Scale, and Nursing Satisfaction Questionnaire were used to evaluate depressive symptoms, anxiety symptoms, and nursing satisfaction before and after intervention. Covariance analysis was used to compare the differences between the two groups before and after the intervention. Results: A total of 62 patients with mild to moderate depression were enrolled, with 31 patients in the intervention group and 31 patients in the control group. Before the intervention, there were no statistically significant differences in gender, age, course of disease, educational level, marital status, depression symptoms score, anxiety symptoms score, and nursing satisfaction score between the two groups (all P>0.05). After the intervention, the scores of depression and anxiety symptoms in the intervention group decreased by 8.87 and 5.01 points, respectively, compared with those before the intervention, and the scores of depression and anxiety symptoms in the control group decreased by 2.52 and 1.16 points, respectively (all P<0.05). After the intervention, the scores of depression and anxiety symptoms in the intervention group decreased more than those in the control group (both P<0.05). The nursing satisfaction score of the intervention group increased by 6.57 points on average compared with that before the intervention, and that of the control group increased by 4.23 points on average (both P<0.05). There was no statistically significant difference in the increase of nursing satisfaction scores between the two groups before and after intervention (P>0.05). Conclusion The "Internet plus" continuous intervention has a good effect on improving the depressive symptoms and anxiety symptoms of patients with depression after haspital discharge, which can consolidate the treatment effect and improve nursing satisfaction.

Objective:To investigate the predictive value of serum signal lymphocyte activation molecule family member 8(SLAMF8)levels for post-stroke cognitive impairment(PSCI).Methods:The GSE122063 dataset was selected from the Gene Expression Omnibus(GEO), and key genes associated with vascular dementia were identified using STRING network and Cytoscape software.This prospective cohort study involved 123 patients with acute cerebral infarction(ACI)who were admitted to the Department of Neurology at Jiangsu University Affiliated Hospital from January to December 2023.Patients were followed up for six months and categorized into PSCI and post-stroke non-cognitive impairment(PSNCI)groups based on the occurrence of PSCI.General data from both groups at baseline, as well as the Mini-Mental State Examination(MMSE)and Montreal Cognitive Assessment Scale(MoCA)scores at the six-month follow-up, were collected.Baseline serum levels of SLAMF8 and stabilin-1(STAB1), along with serum levels of interleukin-1β(IL-1β)and interleukin-6(IL-6)at the six-month follow-up, were measured.Pearson correlation analysis was used to assess the correlation between variables, while logistic regression analysis was employed to determine baseline factors influencing the occurrence of PSCI.Receiver Operating Characteristic(ROC)curves were plotted to analyze the predictive value of variables for PSCI occurrence.Results:The Cytoscape software identified SLAMF8 and STAB1 as key genes associated with vascular dementia, utilizing maximum neighborhood component density(DNMC)and eccentricity algorithms on the GSE122063 dataset.In the cohort study, patients in the PSCI group exhibited higher baseline NIHSS scores and serum SLAMF8 levels compared to the PSNCI group( t=3.033, 5.422; P<0.01). Additionally, they demonstrated significantly lower MMSE and MoCA scores( t=16.340, 18.634; P<0.001)and higher serum levels of IL-1β and IL-6( t=2.633, 2.632; P<0.05)at the 6-month follow-up.No significant difference was observed in baseline STAB1 levels between the two groups( t=1.280, P>0.05). In the PSCI group, there was no significant correlation between baseline serum SLAMF8 levels and admission NIHSS scores( r=0.257, P=0.082); however, SLAMF8 showed a negative correlation with both MMSE scores( r=-0.711, P<0.001)and MoCA scores( r=-0.686, P<0.001)at the 6-month follow-up.Logistic regression analysis indicated that baseline serum SLAMF8 levels( OR=1.142, P=0.001)and NIHSS scores( OR=1.094, P=0.007)were risk factors for the development of PSCI in patients with acute cerebral infarction(ACI). ROC curve analysis revealed that the area under the ROC curve(AUC)for baseline serum SLAMF8 levels in predicting PSCI occurrence in ACI patients was 0.776, while the AUC for the combined prediction using both SLAMF8 and NIHSS scores was 0.796.Furthermore, baseline serum SLAMF8 levels were positively correlated with serum IL-1β levels( r=0.652, P<0.001)and IL-6 levels( r=0.710, P<0.001)at the 6-month follow-up. Conclusions:The serum SLAMF8 level, exhibiting early high expression in ACI patients, may serve as a potential biological marker for predicting the occurrence of PSCI.

Objective:To develop PixelSIFT-UNet, a novel semantic segmentation model that integrates deep learning with scale-invariant feature transform (SIFT) algorithm to improve the segmentation accuracy of oral mucosal lesions.Methods:This investigation utilized 838 standard clinical white light images of oral mucosal diseases acquired from January 2020 to December 2022 at the Stomatology Hospital Zhejiang University School of Medicine. Randomization was achieved through Python′s random.seed function implementation. The random sample function was subsequently applied for sampling distribution. The dataset was stratified into three subsets with a 6∶2∶2 ratio: training ( n=506), validation ( n=166), and testing ( n=166). Lesion boundaries were annotated using Labelme software, and a PixelSIFT-UNet-based deep learning model was developed with VGG-16 and ResNet-50 backbone networks. Model parameters were optimized using the validation set, and performance metrics [including Dice coefficient, mean intersection over union (mIoU), mean pixel accuracy (mPA), and Precision] were assessed on the test set. The model′s performance was benchmarked against conventional semantic segmentation frameworks (U-Net and PSPNet). Results:The developed PixelSIFT-UNet model could achieve precise segmentation of three common oral mucosal lesions: oral lichen planus, oral leukoplakia, and oral submucous fibrosis. Utilizing VGG-16 as the backbone network, the model achieved Dice coefficient, mIoU, mPA, and Precision values of 0.642, 0.699, 0.836, and 0.792, respectively. Implementation with ResNet-50 backbone network yielded metrics of 0.668, 0.733, 0.872 and 0.817, demonstrating significant improvements across all performance indicators compared to conventional U-Net model (relevant metrics: 0.662, 0.717, 0.861 and 0.809) and PSPNet model (relevant metrics: 0.671, 0.721, 0.858 and 0.813).Conclusions:The proposed PixelSIFT-UNet architecture demonstrates superior performance in oral mucosal lesion segmentation tasks, surpassing conventional semantic segmentation models and providing robust quantitative improvements in segmentation accuracy.

Objective To investigate the early dynamic changes of biomarkers associated with capillary leak syndrome(CLS)in patients with severe acute pancreatitis(SAP)and their correlation with multiple organ failure(MOF).Methods A total of 171 SAP patients admitted to the West China Centre of Excellence for Pancreatitis,West China Hospital,Sichuan University between September 1,2019 and December 31,2020 were enrolled for this study.The patients were divided into MOF and non-MOF groups based on the occurrence of MOF in the first 5 days of hospitalization,and were further divided into subgroups based on the presence of moderate-to-severe intra-abdominal hypertension(IAH).We performed dynamic monitoring of the blood biomarkers(hematocrit[HCT].blood urea nitrogen[BUN].and creatinine[Cr]),plasma proteins(albumin[Alb].total protein[TP].and non-albumin plasma proteins[NAPP]),and intra-abdominal pressure.Trends in these indicators across groups were analyzed comprehensively.Results No significant differences in baseline data between the two groups were observed.The baseline data of the 2 groups were comparable.The MOF group had significantly higher rates of persistent systemic inflammatory response syndrome(SIRS)lasting 48 hours(91.3％vs.71.8％),ICU admission(70.4％vs.17.6％),and length-of-stay([32±17.7]days vs.[19.0±12.2]days)compared to those of the non-MOF group(P＜0.05).The incidences of respiratory,circulatory,and renal failures were higher in the MOF group than those in the non-MOF group,showing significant differences in circulatory failure(69％vs.3.5％)and renal failure(65.5％vs.3.5％)(P＜0.05).In the first 5 days of hospitalization,the MOF group showed significantly elevated BUN and Cr levels,while Alb and TP levels dropped rapidly upon admission and then gradually recovered.The NAPP level of the MOF group continued to decrease after admission,and on the third day after admission,the NAPP level was lower than that of the Non-MOF group,showing statistically significant difference(P＜0.001).The Alb/NAPP ratio of the MOF group decreased significantly on day 1 and then rapidly increased,showing significant differences between the groups on days 3 and 4(P=0.001).Subgroup analysis of MOF patients with moderate-to-severe IAH revealed similar trends in the dynamic changes and the overall changes in the indicators,and the difference was even more pronounced.The mixed linear model showed that the average levels of HCT,BUN,Alb/NAPP,and Alb/TP were higher and increased over time in the MOF combined with IAP subgroup(P＜0.001).Conclusion The CLS model of SAP patients is validated,confirming that CLS is a key factor in the progression from SIRS to MOF.The loss of NAPP is an early and important indicator of CLS persistence and progression to MOF.Additionally,moderate-to-severe IAH accelerates the deterioration of MOF.These findings provide valuable insights into the potential mechanisms of MOF and warrant further validation through large-scale prospective studies.

AIM:To explore the potential mecha-nism of arecoline in promoting oral submucous fi-brosis based on key factors of phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR)pathway.METHODS:SD rats were randomly divided into arecoline low-dose group,arecoline medium-dose group,and are-coline high-dose group(5,10,and 15 mg/mL).The oral buccal mucosa was injected with the corre-sponding concentration of arecoline(ANE)solution to induce the establishment of oral submucous fi-brosis(OSF)models,with 8 rats in each group.An-other 8 unmodeled rats were selected as the blank group,and the changes in mouth opening of the rats were detected after 8 weeks of grouping and intervention.HE and Masson staining were used to observe the pathological changes of oral buccal mucosa,measure the length of epithelial staple process and calculate collagen volume fraction.Western blot and qRT-PCR were used to detect the expression of collagen-Ⅰ(COL-Ⅰ),E-cadherin,fibro-nectin(FN)and PI3K/Akt/mTOR signaling pathway-related proteins and mRNA in rat oral buccal muco-sa.The levels of tumor necrosis factor(TNF)-α,in-terleukin(IL)-1β and transforming growth factor(TGF)-β1 in rat serum were detected by ELISA.Hu-man immortalized keratinocytes(HaCaT cell line)were cultured in vitro,and the effects of different concentrations of arecoline,PI3K activator,and PI3K inhibitor on the survival rate of HaCaT cells were investigated by CCK-8 method.According to the results of CCK-8,the concentration of arecoline 75 μg/mL,the concentration of PI3K activator 10μmol/L,and the concentration of PI3K inhibitor 2μmol/L were selected as the subsequent experi-mental concentrations.The cells were set as blank group,arecoline group,PI3K activator group,PI3K inhibitor group,and arecoline+PI3K inhibitor group.The mRNA expression levels of COL-Ⅰ,E-cad-herin,FN,PI3K,Akt,and mTOR in each group of cells were detected by qRT-PCR.The levels of TNF-α,IL-1β and TGF-β1 in each group of cells were de-tected by ELISA.RESULTS:Compared with the blank group,the arecoline low-dose group,the are-coline medium-dose group,and the arecoline high-dose group significantly reduced the mouth open-ing,significantly shortened the length of the epi-thelial staple process,significantly increased the collagen volume fraction,inflammatory cell infiltra-tion,and severe pathological damage.The protein expression levels of COL-Ⅰ,FN,p-PI3K,p-Akt,and p-mTOR were up-regulated,and the protein expres-sion levels of E-cadherin were down-regulated.The mRNA expressions of COL-Ⅰ,FN,PI3K,Akt,and mTOR were significantly increased.The mRNA ex-pression of E-cadherin was significantly reduced,and the levels of TNF-α,IL-1β,and TGF-β1 were sig-nificantly increased(all P＜0.05 or P＜0.01).Com-pared with the blank group,the mRNA expression levels of COL-Ⅰ,FN,PI3K,Akt,and mTOR in the cells of the arecoline group and the PI3K activator group were up-regulated,and the mRNA expression lev-els of E-cadherin were down-regulated.Compared with the blank group,the mRNA expression levels of COL-Ⅰ,FN,PI3K,Akt,and mTOR in the cells of the PI3K inhibitor group were down-regulated,and the mRNA expression levels of E-cadherin were up-regulated.Compared with the PI3K inhibitor group,the mRNA expression levels of COL-Ⅰ,FN,PI3K,Akt,and mTOR in the cells of the arecoline+PI3K inhibi-tor group were up-regulated,the mRNA expression levels of E-cadherin were down-regulated,and the levels of TNF-α,IL-1β,and TGF-β1 were significant-ly increased(all P＜0.05 or P＜0.01).CONCLUSION:Arecoline can significantly promote oral submucous fibrosis,which may play a pro-fibrotic role by up-regulating the PI3K/Akt/mTOR signaling pathway.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.
