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: The contraction behaviors of cardiomyocytes (CMs), especially contraction synchrony, are crucial factors reflecting their maturity and response to drugs. A wider field of view helps to observe more pronounced synchrony differences, but the accompanied greater computational load, requiring more computing power or longer computational time. METHODS: We proposed a method that directly correlates variations in optical field brightness with cardiac tissue contraction status (CVB method), based on principles from physics and photometry, for rapid video analysis in wide field of view to obtain contraction parameters, such as period and contraction propagation direction and speed. RESULTS: Through video analysis of human induced pluripotent stem cell (hiPSC)-derived CMs labeled with green fluorescent protein (GFP) cultured on aligned and random nanofiber scaffolds, the CVB method was demonstrated to obtain contraction parameters and quantify the direction and speed of contraction within regions of interest (ROIs) in wide field of view. The CVB method required less computation time compared to one of the contour tracking methods, the LucasKanade (LK) optical flow method, and provided better stability and accuracy in the results. CONCLUSION This method has a smaller computational load, is less affected by motion blur and out-of-focus conditions, and provides a potential tool for accurate and rapid analysis of cardiac tissue contraction synchrony in wide field of view without the need for more powerful hardware.

ObjectiveTo investigate the effect and mechanism of Bukan Yilidan on perimenopausal psycho-cardiac disease by mitochondrial autophagy mediated by dynamin-related protein 1（Drp1）/phosphatase and tensin homolog（PTEN） induced putative kinase 1（PINK1）/Parkin pathway. MethodsSixty rats were randomly divided into the blank group， model group， western medicine group（isosorbide mononitrate 7.2 mg·kg^-1+sertraline hydrochloride tablets 18 mg·kg^-1）， Bukan Yilidan low， medium and high dose groups（2.59， 5.18， 10.35 g·kg^-1）， with 10 rats in each group. Except for the blank group， the rat model of perimenopausal psycho-cardiac disease was prepared by ovariectomy（OVX） combined with high-fat feeding， chronic unpredictable mild stress（CUMS） and subcutaneous multi-point injection of isoproterenol hydrochloride. After successful modeling， the general state and tongue image of rats were observed. The depression status of rats in vivo was evaluated by open field test， sucrose preference test， forced swimming immobility time and grip strength value， and the cardiac function of rats was evaluated by electrocardiogram and echocardiography. The levels of serum norepinephrine（NE）， dopamine（DA） and 5-hydroxytryptamine（5-HT） were detected by enzyme-linked immunosorbent assay（ELISA）， and biochemical detection was used to assess myocardial injury by measuring serum levels of high-density lipoprotein cholesterol（HDL-C）， low-density lipoprotein cholesterol（LDL-C）， triglyceride（TG）， total cholesterol（TC）， aspartate aminotransferase（AST）， alanine aminotransferase（ALT）， lactate dehydrogenase（LDH） and creatine kinase isoenzyme（CK-MB）. Hematoxylin-eosin（HE） and Nissl staining were used to observe the pathological status of hippocampus and myocardial tissue in rats， the status of mitophagosomes in hippocampus and myocardium was observed by transmission electron microscope（TEM）， and Western blot was used to detect the contents of Drp1， mitochondrial fusion protein 2（Mfn2）， optic atrophy protein 1（OPA1）， PINK1， Parkin， p62 and microtubule-associated protein light chain 3B（LC3B） in hippocampus and myocardium. ResultsCompared with the blank group， the food intake and water intake of rats in the model group decreased， the hair was dark yellow， the gloss and smoothness decreased， the spirit was depressed， the tongue was light purple or dark purple， accompanied by petechiae or ecchymosis， the sublingual collaterals were purple and black， and the tongue coating was white and smooth. The indexes of open field test， grip strength and sucrose preference of rats decreased significantly， and the immobility time of forced swimming increased significantly（P<0.01）. Electrocardiogram and echocardiography showed that ST segment was significantly depressed， and left ventricular fractional shortening（LVFS） and left ventricular ejection fraction（LVEF） were significantly decreased（P<0.05， P<0.01）. Pathological observation showed that the number of hippocampal neurons and myocardial cells decreased， and the structural damage was obvious. The levels of serum TC， TG， LDL-C， CK-MB， LDH， AST and ALT increased， while the levels of HDL-C， 5-HT， DA and NE decreased（P<0.05， P<0.01）. TEM showed obvious mitochondrial damage in hippocampus and myocardial tissue. The protein expressions of Drp1， PINK1， Parkin and p62 in hippocampus and myocardium were increased， while the protein expressions of OPA1， Mfn2 and LC3BⅡ/Ⅰ were decreased（P<0.05， P<0.01）. Compared with the model group， the mental state， body curling up， fear of cold and other symptoms of rats in each administration group were improved， and the degree of pale purple or dark purple tongue was reduced. The scores of open field test， grip strength， sucrose preference， LVFS and LVEF were increased， and the immobility time of forced swimming was shortened（P<0.05， P<0.01）. The ST segment of electrocardiogram had a significant recovery（P<0.01）， pathological observation showed that the damage of nerve cells and myocardial tissue was improved. The levels of serum TC， TG， LDL-C， CK-MB， LDH， AST and ALT decreased， while the levels of HDL-C， 5-HT， DA and NE increased（P<0.05， P<0.01）. TEM showed that mitochondrial damage was reduced in hippocampal neurons and cardiomyocytes with visible mitochondrial autophagosomes. The protein expressions of Drp1， PINK1， Parkin and p62 in hippocampus and myocardium were decreased， while the protein expressions of OPA1， Mfn2 and LC3BⅡ/Ⅰ were increased（P<0.05， P<0.01）. ConclusionBukan Yilidan can alleviate depression， lipid metabolism disorder and myocardial ischemia injury in rats with perimenopausal psycho-cardiac disease， and its mechanism may be related to inhibiting Drp1/PINK1/Parkin signaling pathway and enhancing mitochondrial autophagy.

ObjectiveTo analyze the influencing factors of pulmonary dysfunction among community-based population at high-risk for chronic obstructive pulmonary disease (COPD), and to establish a risk assessment model to provide a reference basis for accelerating the beforehand prevention and control of COPD and promoting the respiratory health of community-based residents. MethodsIndividuals aged >35 years old, with at least one risk factor except age illustrated in the Guidelines for Primary Diagnosis and Treatment of Chronic Obstructive Lung Disease (2018), and participated in the early screening for COPD from July 2022 to December 2023 were selected as the research subjects, and their lung function was assessed by the forceful expiratory volume in the first second after inhalation of bronchodilator (FEV₁)/ forced vital capacity (FVC) <70% and/or the ratio of FEV₁ to predicted value (FEV₁%Pred) <80% as the diagnostic criteria. In addition, risk factors related to pulmonary dysfunction were analyzed for the establishment of risk assessment model. ResultsA total of 823 individuals aged between 35‒76 years were included, among which 298 (36.21%) were diagnosed with pulmonary dysfunction, 167 (20.29%) with COPD, and 131 (15.92%) with preserved ratio but impaired spirometry. Logistic regression analysis revealed that male gender, increasing age, more frequent smoking, insufficient physical activity, recurrent wheezing, the presence of post-exercise wheezing or coughing, insensitive to airborne allergens, and history of chronic bronchitis or bronchial asthma were correlated with pulmonary dysfunction. The incidence rate of pulmonary dysfunction was 1.99 times higher in males than that in females, 1.81 times more common in those aged between 70‒76 years than those aged <60 years, 2.42 times more common in those who smoked 50‒200 pack-years than in those who smoked 0‒14 pack-years, 1.78 times higher in those who underwent physical activity <600 MET‑min·week^-1 than in those who underwent physical activity ≥600 MET‑min·week^-1, 2.61 times higher in those suffered recurrent wheezing than in those did not, 1.53 times higher in those with symptoms of post-exercise wheezing or coughing than in those without, 1.61 times higher in those insensitive to airborne allergens than those sensitive, 2.02 times higher in patients with chronic bronchitis than in those without, and 2.41 times higher in patients with bronchial asthma than in those without. The risk assessment model for pulmonary dysfunction constructed on this basis had a total score of 28 points, and the area under the subject operating characteristic (ROC) curve was 0.72, reaching the cut-off point of ROC curve while taking scores ≥10 points as the cut-off value for pulmonary dysfunction. ConclusionIn community-based high-risk COPD population, the incidence rate of pulmonary dysfunction is higher in males than that in females, in addition, which increases with the advancement of age. Smoking,insufficient physical activity,recurrent wheezing,post-exercise wheezing or coughing,insensitive to airborne allergens,and history of chronic bronchitis or bronchial asthma are high risk factors for pulmonary dysfunction. The risk assessment model constructed based on these factors has a good predictive effect in screening high-risk population of COPD, but its effectiveness in screening people at general risk needs to be further validated.

BACKGROUND: Meningeal metastasis (MM) is a form of malignant metastasis where tumor cells spread from the primary site to the pia mater, dura mater, arachnoid, subarachnoid space, and other cerebrospinal fluid compartments. Lung cancer is one of the most common malignant tumor types with MM. MM not only signifies that the lung cancer has progressed to an advanced stage but also leads to a range of severe clinical symptoms due to meningeal involvement. Currently, the risk factors associated with the development of MM are not fully elucidated. The aim of this study was to investigate the risk factors for MM in patients with lung adenocarcinoma (LUAD) who underwent non-surgical interventions, in order to identify LUAD patients at high risk for MM. METHODS: This retrospective study analyzed the clinical data of patients diagnosed with LUAD at the First Affiliated Hospital of Zhengzhou University from January 2020 to July 2024. Missing data were imputed using multiple imputation methods, and risk factors were identified through LASSO, univariate, and multivariate Logistic regression analyses. RESULTS: A total of 170 patients with LUAD were included in this study and divided into two groups: 87 patients with MM and 83 patients without MM. Univariate and multivariate Logistic regression analyses revealed that younger age at diagnosis (P=0.004), presence of the epidermal growth factor receptor (EGFR) L858R gene mutation (P=0.008), and concurrent liver metastasis at baseline (P=0.004) were independent risk factors for developing MM in LUAD patients who did not undergo surgical intervention. Conversely, higher baseline globulin levels (P=0.039) and the presence of the anaplastic lymphoma kinase (ALK) gene mutation (P=0.040) were associated with a reduced risk of MM development. CONCLUSIONS Age at diagnosis, EGFR L858R mutation status, ALK gene mutation status, concurrent liver metastasis, globulin levels at baseline were significantly associated with the risk of developing MM in patients with LUAD patients who did not undergo surgical intervention. For patients diagnosed at a younger age, carrying the EGFR L858R mutation, or presenting with baseline liver metastasis, early implementation of tertiary prevention strategies for MM is crucial. Regular monitoring of MM status should be conducted in these high-risk groups.

Objective:To explore the genetic and clinical characteristics of Guizhou patients with enlarged vestibular aqueduct（EVA） syndrome through combined SLC26A4 variant analysis and clinical phenotype analysis. Methods:Seventy-two EVA patients underwent comprehensive genetic testing using a multiplex PCR-based deafness gene panel and next-generation sequencing（NGS）. The audiological and temporal bone imaging characteristics were compared across mutation subtypes. Results:A total of 27 pathogenic loci of SLC26A4 were detected in 72 patients, including c.919-2A>G in 79.2%（57/72）. A novel deletion（c.1703_1707+6del） was discovered. Among 65 cases, truncated mutations were 89.2%（58/65）, 52.3%（34/65）, 28（43.1%） and 7（10.8%）. No significant differences were observed in the midpoint diameter of the vestibular aqueduct and the incidence of incomplete partitioning typeⅡ（IP-Ⅱ） of the cochlea among the three groups of patients. Moreover, there was no difference in the midpoint diameter of different vestibular pipes or the combination with IP-Ⅱ. Conclusion:The most common mutation site of SLC26A4 in EVA patients in Guizhou is c.919-2A>G, though genotype-phenotype correlations remain elusive. The detection of 27 mutation sites and the discovery of new mutation sites suggested the precise diagnostic significance of NGS technology in EVA patients in Guizhou.
