OBJECTIVE To investigate the actual construction and operation status of established and under-construction centralized （cloud） prescription review centers （shortened for “prescription review center”） of close-knit county-level medical consortium in a certain city， so as to provide reference for improving the construction quality of the prescription review center. METHODS An online questionnaire survey was conducted to collect the data from 51 established and under-construction prescription review center in the city， covering basic information， funding sources， talent management， system construction， review rule maintenance， prescription review practices， prescription evaluation， data utilization， and current challenges. The collected data were summarized and analyzed. RESULTS A total of 51 valid questionnaires were retrieved， covering 32 established and 19 under-construction prescription review center. Among the 32 established prescription review centers， the main funding sources for their construction came from government financial allocations， accounting for 56.25%. Only 25.00% of prescription review center had review pharmacists who fully met national qualification requirements， and just 55.00% updated more than 10 review rule entries per month on average. Outpatient prescription verification realized full coverage， but 37.50% of prescription review centers only supported rationality verification of single prescriptions， and 50.00% could not retrieve laboratory and examination results to assist in prescription review. Additionally， 40.62% of prescription review center had not regularly conducted prescription evaluations for primary care institutions. The data from prescription review center was mainly used to support medication monitoring. Among the 19 prescription review centers currently in the planning stage， 63.16% had no identified funding sources. CONCLUSIONS The operation and construction of prescription review center in the city face challenges， such as funding shortages， absence of collaborative incentive mechanisms， and insufficient manpower.It is suggested that the state should issue a unified standard for the construction of the prescription review center as soon as possible， and local health administrative departments should formulate supporting policies and clarify assessment indicators in combination with the actual situation of the region.

This paper explores the differentiation and treatment strategies for pediatric IgA vasculitis based on the correlation between blood trubidity theory and oxidative stress. It is proposed that pediatric IgA vasculitis follows an evolution of pathogenesis characterized by "deficiency of healthy qi leading to turbidity generation， accumulation of turbid toxin， and toxin damage to the collateral vessels"， which corresponds to the pathological process of oxidative stress， namely decreased antioxidant capacity with accumulation of reactive oxygen species， metabolite deposition， and endothelial cell injury. A staged treatment strategy is proposed. In the acute stage， wind-toxin invading the colla-terals and reckless movement of heat in the blood are the main manifestations， for which the treatment should focus on dispelling wind and venting pathogens， resolving toxins and unblocking the collaterals， with a modified Yinqiao Powder （银翘散） and Xijiao Dihuang Decoction （犀角地黄汤） to regulate oxidative stress burst. In the prolonged stage， intermingling of turbidity and stasis with collateral obstruction is emphasized； treatment should focus on resolving turbidity and dispelling stasis， harmonizing the blood and stabilizing the collaterals， and a modified Simiao Powder （四妙散） and Taohong Siwu Decoction （桃红四物汤） can be used to improve microcirculatory dysfunction. In the remission stage， when healthy qi remains insufficient and residual pathogens persist， treatment should focus on strengthening the root and clearing the source， reinforcing healthy qi and nourishing the collaterals， for which modified Zhibai Dihuang Pill （知柏地黄丸） and Yupingfeng Powder （玉屏风散） is suggested to rebuild the antioxidant defense system.

OBJECTIVE This study aims to establish a prompt engineering system for large language models in pharmaceutical popularization， and provide references for pharmacists to carry out efficient and standardized science popularization work. METHODS This study systematically expounded the principles and classifications of prompt engineering， as well as its effect on alleviating problems including model output hallucinations and poor interpretability. The design and optimization strategies of prompt engineering were defined for two core scenarios， namely text-to-text and text-to-image. Typical examples were adopted to compare the output effects before and after application. In addition， the limitations of prompt engineering applied in pharmaceutical popularization at the current stage were summarized. RESULTS In the two major scenarios of pharmaceutical popularization， well-designed prompt engineering improved the accuracy， readability and efficiency of outputs generated by large language models， and produced personalized popularization content adapted to clinical practice. CONCLUSIONS Prompt engineering can effectively improve the output quality of pharmaceutical popularization. The formulated standardized prompt engineering templates tailored for pharmaceutical popularization， can help pharmacists improve the efficiency and quality of popularization content creation.

OBJECTIVE To investigate the mechanism of Yifei xuanfei jiangzhuo formula （YFXF） against vascular dementia （VD）. METHODS The differentially expressed genes of YFXF （YDEGs） were obtained by network pharmacology. High-risk genes were screened from YDEGs by using the nomogram model. The optimal machine learning models in generalized linear， support vector machine， extreme gradient boosting and random forest models were screened based on high-risk genes. VD model rats were established by bilateral common carotid artery occlusion， and were randomly divided into model group and YFXF group （12.18 g/kg， by the total amount of crude drugs）， and sham operation group was established additionally， with 6 rats in each group. The effects of YFXF on behavior （using escape latency and times of crossing platform as indexes）， histopathologic changes of cerebral cortex， and the expression of proteins related to the secreted phosphoprotein 1 （SPP1）/phosphoinositide 3-kinase （PI3K）/protein kinase B （aka Akt） signaling pathway and the mRNA expression of SPP1 in cerebral cortex of VD rats were evaluated. RESULTS A total of 6 YDEGs were obtained， among which SPP1， CCL2， HMOX1 and HSPB1 may be high-risk genes of VD. The generalized linear model based on high-risk genes had the highest prediction accuracy （area under the curve of 0.954）. Compared with the model group， YFXF could significantly shorten the escape latency of VD rats， significantly increase the times of crossing platform （P＜0.05）； improve the pathological damage of cerebral cortex， such as neuronal shrinkage and neuronal necrosis； significantly reduce the expressions of SPP1 protein and mRNA （P＜0.05）， while significantly increase the phosphorylation levels of PI3K and Akt （P＜0.05）. CONCLUSIONS VD high-risk genes SPP1， CCL2， HMOX1 and HSPB1 may be the important targets of YFXF. YFXF may play an anti-VD role by down-regulating the protein and mRNA expressions of SPP1 and activating PI3K/Akt signaling pathway.

Objective: To establish aNBR1-knockout lung cancer mouse model through CRISPR-Cas9 technology by using adeno-associated virus(AAV) as a vector to specifically inhibitNBR1expression and to investigate the impact ofNBR1knockout on tumor growth and immune cell infiltration and regulation. Methods: sgRNAs targeting mouseNBR1(Gene ID: 17966) was designed using the online tool CRISPOR(http://crispor.tefor.net/crispor.py). AAV6 was utilized as the vector for sgRNA delivery, and the efficiency of gene knockout was confirmed using PCR and DNA sequencing methods. To determine the best AAV infection approach in mice, 6 C57BL/6J mice were randomly divided into intranasal and endotracheal groups. After 28 days, lung tissue sections were assessed for enhanced green fluorescent protein expression to identify the more efficient infection method for subsequent experiments. Lung tumor growth, as well as immune cell infiltration and activation status in tumor tissues, were detected using methods including HE staining, immunohistochemistry, immunofluorescence, and flow cytometry. Results: DNA sequencing and immunofluorescence results indicated successful construction of the AAV6-U6-sgNBR1-CAG-Cre-GFP vector with stable knockout efficiency. Fluorescence microscopy showed higher efficiency of lung infection in mice through intratracheal administration(P<0.05). HE staining revealed reduced tumor area in mouse lungs after targetedNBR1knockout compared to the control group(P<0.01). Immunofluorescence and flow cytometry results demonstrated enhanced functional activity of CD8+T lymphocytes in lung cancer tissues of mice with targetedNBR1knockout, characterized by increased effector T lymphocytes and decreased exhausted T lymphocytes(P<0.01). Conclusion Using CRISPR/Cas9 technology, we construct a lung cancer mouse model with targetedNBR1knockout. We verify that targeted inhibition of NBR1 expression significantly enhances the functional activity of CD8+T lymphocytes in lung tissues, resulting in suppressed tumor growth, reduced tumor burden, and extended survival in lung cancer mice. This study lays an experimental foundation for investigations into the mechanisms and functions ofNBR1and other genes in lung adenocarcinoma cells.

Surgery is the mainstay of lung cancer treatment options.Traditionally,lobectomy has held its place as the gold standard for treating localized lung cancer,while sublobar resection,including wedge resection and segmentectomy,was primarily considered as an alternative,often reserved for patient ineligible to sustain a radical intervention.However,with the widespread application of computed tomography(CT)to clinical practice,the increasing detection rate of pulmonary ground glass nodules(GGNs)has reshaped this landscape.Ground glass opacity(GGO)in persistent lung nodules is an indicative factor of a favorable prognosis,typically corresponding to pathological changes such as atypical adenomatous hyperplasia(AAH),adenocarcinoma in situ(AIS),or adenocarcinomas predominantly featuring a lepidic growth pattern.A large number of retrospective studies have shown that sublobar resection can achieve satisfactory therapeutic outcomes for such lesions.A series of prospective studies from Japan have confirmed that for early-stage lung cancers dominated by GGOs,sublobar resection is also a viable curative surgical option.The follow-up data showed that there was no statistical difference in the survival status of these patients compared with that of pulmonary lobectomy.This article aims to delve into the role of limited lung resection in the context of lung adenocarcinoma presenting with GGO features.

Objective:To investigate the clinical outcome of endovascular treatment vs. drug treatment in patients with symptomatic non-acute long-segment occlusion of the internal carotid artery. Methods:Based on prospective cohort registration research data, patients with symptomatic non-acute long-segment occlusion of internal carotid artery were retrospectively included. They were divided into a drug treatment group and an endovascular treatment group according to the actual treatment received. The latter was further divided into a successful recanalization group and an unsuccessful recanalization group. The endpoint events included ipsilateral ischemic stroke, any stroke, and all-cause death. Multivariate logistic regression analysis was used to compare the endpoint events between groups during the perioprocedural period (within 30 days), and multivariate Cox proportional hazards model was use to compare the endpoint events between the groups during the long-term follow-up. Results:A total of 684 patients were included, of which 570 (83.33%) were male, median aged 63 years (interquartile range, 56-70 years). Three hundred and fifty-three patients (51.6%) received drug treatment; 331 (48.4%) received endovascular treatment, of which 161 (48.6%) had successful recanalization. The median follow-up time was 1 223 days (interquartile range, 646.5-2 082 days), with 109 patients (15.9%) experiencing stroke recurrence events (including 87 ipsilateral ischemic stroke) and 78 (11.4%) experiencing all-cause mortality. The risk of any stroke during the perioprocedural period in the successful recanalization group was significantly higher than that in the drug treatment group (odds ratio 3.679, 95% confidence interval 1.038-13.036; P=0.044), but the risk of ipsilateral ischemic stroke recurrence (risk ratio 0.347, 95% confidence interval 0.152-0.791; P=0.012) and all-cause mortality (risk ratio 0.239, 95% confidence interval 0.093-0.618; P=0.003) during the long-term follow-up were significantly lower than those in the drug treatment group. Conclusions:In patients with symptomatic non-acute long-segment occlusion of the internal carotid artery, endovascular treatment can increase the risk of stroke recurrence within 30 days, but successful recanalization can reduce the risks of long-term ipsilateral ischemic stroke recurrence and all-cause mortality.

Objective To explore the correlation of baseline CCL19+dendritic cell(CCL19+DC)infiltration in lung adenocarcinoma microenvironment with immunotherapy efficacy and CD8+T cell infiltration.Methods We retrospectively analyzed the data of patients with lung adenocarcinoma hospitalized at First Affiliated Hospital of Henan University of Science and Technology from January,2020 to December,2023,and collected tissue samples from 96 patients undergoing immunotherapy for assessing CCL19+DC and CD8+T cell infiltration using immunofluorescence assay.We evaluated the predictive value of baseline CCL19+DCs for patient responses to immunotherapy using receiver-operating characteristics(ROC)curves and analyzed the correlations of baseline CCL19+DC expression with immunotherapy efficacy and CD8+T cell and cytotoxic T lymphocyte(CTL)infiltrations.In co-culture systems of lung adenocarcinoma PC9 cells,CD8+T cells and DCs(overexpressing CCL19 with or without anti PD-1 antibody treatment),the expressions of granzyme B,perforin,IFN-γ,and Ki-67 in T cells were analyzed using flow cytometry.Results The patients with partial or complete remission following immunotherapy had a significantly higher baseline CCL19+DC infiltration level in lung adenocarcinoma tissues than those with poor responses.CCL19+DC infiltration had an area under ROC curve of 0.785,a sensitivity of 75.6%,and a specificity of 62.8%for predicting immunotherapy efficacy.The expression of CD8+T cell surface molecules Granzyme B(P<0.01),Perforin(P<0.01),IFN-γ(P<0.01)and Ki-67(P<0.001)in patients with high expression of CCL19+DC were higher than those in patients with low expression of CCL19+DC.The baseline CCL19+DC infiltration level was positively correlated with immunotherapy efficacy(P=0.003),CTL infiltration of(r=0.6657,P<0.001)and CD8+T cell infiltration(P=0.007).In the co-cultured cells,CCL19 overexpression combined with anti-PD1 treatment of the DCs more strongly enhanced cytotoxicity and proliferation of CD8+T lymphocytes than either of the single treatments(P<0.01 or 0.001).Conclusion The baseline CCL19+DC infiltration level in lung adenocarcinoma microenvironment is positively correlated with immunotherapy efficacy and CTL infiltration and can thus predict the response to immunotherapy.

This paper summarized Professor PENG Peichu's experience in the differentiation and treatment of prostate cancer in three phases and four stages. It is considered that prostatic cancer is categorized into root deficiency and branch excess， with depletion of healthy qi as the root， and the accumulation of cancer toxin as the minifestation. Clinical diagnosis and treatment of prostatic cancer can be divided into three phases and four stages according to the exuberance and decline of pathogenic and healthy qi and the changes of deficiency and excess of yin and yang. In the initial accumulation phase of cancer toxin （yang excess stage）， the key pathogenesis is the accumulation of dampness， heat and static blood， and internal generation of cancer toxin， and the treatment should be resolving toxins， fighting cancer and dispelling yang excess. In the phase of healthy qi deficiency and toxin accumulation （yin deficiency stage）， with the lung and kidney yin deficiency， dampness， heat and static toxin accumulation as the key pathogenesis， the treatment should be centered on mutual generation between metal and water to nourish kidney yin， supplemented with the method of clearing heat and draining dampness， activating blood and resolving toxins， for which self-made Nanbei Formula（南北方）is usually used. In the phase of yang deficiency and cold stagnation （yang deficiency stage and yin excess stage）， with the spleen and kidney yang deficiency， cold dampness stagnation， static heat and toxin accumulation as the key pathogenesis， the treatment should be warming and tonifying spleen and kidney to dissipate cold accumulation； for deficiency of both yin and yang， and excess pathogen obstruction， modified Yanghe Decoction（阳和汤） is recommended， while for yang deficiency， cold congealing and blood stasis， self-made Wenshen Sanjie Formula（温肾散结方） can be used， and for cold dampness binding with cancer toxin， and cold complex with heat， self-made Quanan Formula （泉安方） is advised.
