OBJECTIVE To evaluate the influence of pharmaceutical quality control on the efficiency and outcomes of standardized medication therapy management （MTM） services for patients with coronary heart disease by using Economic， Clinical and Humanistic Outcomes （ECHO） model. METHODS This study collected case data of coronary heart disease patients who received MTM services during January-March 2023 （pre-quality control implementation group， n＝96） and June-August 2023 （post-quality control implementation group， n＝164）. Using propensity score matching analysis， 80 patients were selected from each group. The study subsequently compared the economic， clinical， and humanistic outcome indicators of pharmaceutical services between the two matched groups. RESULTS There were no statistically significant differences in baseline data between the two groups after matching （P＞0.05）. Compared with pre-quality control implementation group， the daily treatment cost （16.26 yuan vs. 24.40 yuan， P＜0.001）， cost-effectiveness ratio [23.12 yuan/quality-adjusted life year （QALY） vs. 32.32 yuan/QALY， P＜0.001]， and the incidence of general adverse drug reactions （2.50% vs. 10.00%， P＝0.049） of post-quality control implementation group were decreased significantly； the utility value of the EuroQol Five-Dimensional Questionnaire （0.74± 0.06 vs. 0.71±0.07， P＝0.003）， the reduction in the number of medication related problems （1.0 vs. 0.5， P＜0.001）， the medication adherence score （[ 6.32±0.48） points vs. （6.10±0.37） points， P＝0.001]， and the satisfaction score （[ 92.56±1.52） points vs. （91.95±1.56） points， P＝0.013] all showed significant improvements. Neither group experienced serious adverse drug reactions. There was no statistically significant difference in the incidence of new adverse reactions between the two groups （1.25% vs. 3.75%， P＝0.310）. CONCLUSIONS Pharmaceutical quality control can improve the quality of pharmaceutical care， and the ECHO model can quantitatively evaluate the effect of MTM services， making pharmaceutical care better priced and more adaptable to social needs， thus being worthy of promotion.

Objective To investigate the incidence, severity and longitudinal trajectories of symptoms at various time points in the perioperative period of lung cancer patients, and to provide scientific basis for clinical staff to implement predictive nursing and dynamic management of symptom clusters. Methods A prospective longitudinal investigation was conducted. The patients with lung cancer who underwent thoracoscopic lung surgery in four wards of the Department of Thoracic Surgery in our hospital were investigated by face-to-face and telephone follow-up before surgery, 1-2 days after surgery, on the day of discharge and 2 weeks after discharge. The investigation tool was the revised Chinese version of MD Anderson Symptom Inventory lung cancer specific module. Results A total of 192 patients with lung cancer were included in this study, including 59 males and 133 females, with an average age of (55.68±11.01) years. There were two symptom clusters (respiratory-gastrointestinal and emotional/psychological-disturbed sleep symptom clusters) before surgery, three symptom clusters (respiratory, gastrointestinal, and emotional/psychological-disturbed sleep symptom clusters) 1-2 days after surgery, three symptom clusters (pain-fatigue-emotional/psychological, respiratory, and gastrointestinal symptom clusters) on the day of discharge, and two symptom clusters (pain-fatigue-respiratory and respiratory symptom clusters) 2 weeks after discharge. The composition of symptoms was different in each time point during perioperative period. Conclusion There are four symptom clusters in patients with lung cancer during perioperative period, which are pain-fatigue-disturbed sleep symptoms, gastrointestinal symptoms, respiratory symptoms and emotional/psychological symptoms. The symptom clusters of lung cancer patients at different time points are relatively stable, but the symptoms within the symptom clusters show dynamic changes. Medical staff should attach great importance to and continuously monitor the dynamic changes of perioperative symptom groups of lung cancer patients, do relevant education and nursing in advance, and timely adjust the management plan according to the symptom group evaluation results.

Abstract: This study aims to find out the causes for the dissolution of unqualified samples found during evaluation sampling of lansoprazole enteric-coated preparations by the laser infrared imaging system and orbitrap high resolution mass spectrometry, with suggestions for improvement. Lansoprazole enteric-coated preparations were tested by current standard, the dissolution of a batch of samples was below the limit and other items were in line with the standard. Considering that this product is unstable to acid and alkali, the following exploratory experiments were designed from different dimensions, based on the conclusion of the unannounced inspection of the company, to explore the reasons for the unqualified batch, including the influence of high-temperature and high-humidity storage environment on the key quality properties of the sample, the influence of 2-hour acid resistance test on dissolution result, the imaging of the core and the measure of coating layer thickness, the optimization of chromatographic conditions of related substances, and the analysis of the source of impurities. It was found that improper storage in circulation and poor coating process caused the low dissolution of this batch: the high-temperature and high-humidity storage environment possible in the circulation process led to the decreasing efficacy of disintegrating agent in the samples and thus the difficulty to release the active pharmaceutical ingredient fully; the coating solution could not be uniformly sprayed on the core, resulting in thin isolation layer and different thickness, which then affected the protection of the main drug against acid degradation. The above two reasons together resulted in unqualified dissolution of this batch. The overall quality of lansoprazole enteric-soluble preparation is good, but the formulation and process in some companies need to be optimized; and the temperature and humidity in the circulation process need to be controlled in strict accordance with the regulations.

Objective To study the levels of serum Periostin and interleukin(I1-)-18 in preterm infants with bronchopulmonary dysplasia(BPD),and to analyze their correlation with the severity of the disease and their predictive value for BPD.Methods A total of 62 preterm infants with BPD diagnosed and treated in the hospital from January 2019 to January 2022 were retrospectively selected as the BPD group,and 80 preterm in-fants without BPD during the same period were selected as the non-BPD group.According to the severity of BPD,the infants with BPD were divided into mild subgroup(22 cases),moderate subgroup(24 cases)and se-vere subgroup(16 cases).The serum levels of Periostin and IL-18 were detected by enzyme-linked immu-nosorbent assay.Pearson correlation analysis was used to analyze the correlation between the clinical parameters.Multivariate Logistic regression was used to analyze the influencing factors of BPD,and receiver operating characteristic(ROC)curve was used to analyze the predictive value of each indicator for BPD.Results Compared with the non-BPD group,the BPD group had a significantly higher proportion of infants with pulmonary surfactant(PS)use,neonatal respiratory distress syndrome,apnea,patent ductus arteriosus,and serum levels of Periostin and IL-18,as well as a significantly longer duration of mechanical ventilation,noninvasive respiratory support,and length of hospital stay.The lung function parameters[tidal volume per kilogram(VT/kg),ratio of time to peak tidal expiratory flow to time(TPTEF/TE),ratio of volume to peak tidal expiratory flow to volume(VPEF/VE),expiratory flow at 50％tidal volume(50％TEF),expiratory flow at 75％tidal volume(75％TEF)]and 1,5 min Apgar score of BPD group were lower than that of non-BPD group,and the differences were statistically significant(P＜0.05).The serum levels of Periostin and IL-18 in mild subgroup,moderate subgroup and severe subgroup were increased in turn.The levels of serum Periostin and IL-18 were negatively correlated with pulmonary function indexes(VT/kg,50％TEF,75％TEF,TPTEF/TE,VPEF/VE,P＜0.05).Serum Periostin,IL-18 and neonatal respiratory distress syndrome were independent risk factors for BPD(P＜0.05),and PS was a protective factor(P＜0.05).Serum Periostin,IL-18 and neonatal respiratory distress syndrome were independent risk factors for the severity of BPD(P＜0.05).The area under the curve(95％CI)of serum Periostin and IL-18 alone and in combination for predicting BPD were 0.841(0.814-0.899),0.863(0.820-0.897),0.922(0.878-0.949),respectively.The sensitivity and specificity of combined prediction were 0.902 and 0.825,respectively.The area under the curve of the combination of the two indica-tors for predicting BPD was greater than that of each index alone,and the difference was statistically signifi-cant(Z=5.357,4.894,P＜0.001).Conclusion The levels of serum Periostin and IL-18 are increased in in-fants with BPD,which are related to the severity of BPD and lung function.The combination of serum Perios-tin and IL-18 has a high predictive value for BPD.

Objective:To investigate the characteristics of neointimal hyperplasia (NIH) in patients with in-stent restenosis (ISR) over 5 years post-drug-eluting stent (DES) implantation based on optical coherence tomography (OCT).Methods:In this cross-sectional study, patients with DES-ISR who underwent OCT examination at PLA General Hospital between March 2010 and March 2022 were retrospectively included. All patients were divided into≤5 years DES-ISR group and>5 years DES-ISR group according to the time interval after DES implantation. Quantitative and qualitative analyses were conducted on OCT images to compare the clinical data and lesion characteristics of two patient groups. Furthermore, the independent clinical predictive factors of in-stent neoatherosclerosis (ISNA) were analyzed by multivariable logistic regression.Results:A total of 230 DES-ISR patients with 249 lesions were included, with an age of (63.1±10.4) years and 188 males (81.7%). The median interval after DES implantation was 6 (2, 9) years. There were 117 patients (122 ISR lesions) in the≤5 years DES-ISR group, and 113 patients (127 ISR lesions) in the>5 years DES-ISR group. Compared with≤5 years DES-ISR,>5 years DES-ISR showed more heterogeneous patterns (65.4% (83/127) vs. 48.4% (59/122), P=0.007), diffuse patterns (46.5% (59/127) vs. 31.2% (38/122), P=0.013), macrophage accumulations (44.1% (56/127) vs. 31.2% (38/122), P=0.035) in NIH and higher prevalence of ISNA (83.5% (106/127) vs. 72.1% (88/122), P=0.031). According to multivariable logistic regression, the independent predictive factor for ISNA was female ( OR=0.44, 95% CI 0.21-0.90, P=0.026). Female ( OR=0.48, 95% CI 0.23-0.99, P=0.046) and low-density lipoprotein cholesterol level ( OR=1.62, 95% CI 1.01-2.59, P=0.046) were independent predictive factors, respectively, for lipid ISNA. Calcified ISNA was independently associated with time interval of post-DES implantation ( OR=1.18, 95% CI 1.07-1.29, P=0.001). Conclusion:DES-ISR patients with a time interval of>5 years after stent implantation have a higher prevalence of ISNA and more complex lesions. Gender, the level of low-density lipoprotein cholesterol, and the time interval post-DES implantation are independently correlated with ISNA, lipid ISNA, and calcified ISNA.

Objective To investigate the mechanism of retinal injury in rats caused by light-emitting diodes(LEDs)with different color rendering indexes(CRIs).Methods Totally 20 Sprague-Dawley rats were randomly divided into nor-mal control(NC)group(sunlight),low CRI(CRI-L)group(blue light),medium CRI(CRI-M)group(conventional LED),and high CRI(CRI-H)group(full-spectrum LED),with 5 rats in each group,exposed to light for 12 hours daily for 4 consecutive weeks.Hematoxylin & eosin staining was used to assess morphological changes in the retina.Dihydroethidi-um staining was employed to detect the levels of reactive oxygen species(ROS)in retinal tissues.The messenger ribonu-cleic acid(mRNA)expressions of NOD-like receptor family pyrin domain containing protein 3(NLRP3),Gasdermin D(GSDMD)and Caspase-1 were analyzed by real-time quantitative polymerase chain reaction(RT-qPCR),and their protein expressions were measured through immunohistochemical staining.Environmental light spectra were measured using a spectroradiometer.Results Rats in the CRI-L group showed the thinnest retina,followed by the CRI-M group and CRI-H group.The fluorescence intensity of ROS in the NC group,CRI-L group,CRI-M group and CRI-H group was 1.000±0.046,25.060±1.732,14.530±3.776 and 1.821±0.587,respectively.The ROS level in the CRI-H group was significantly lower than that in the CRI-L group and CRI-M group(both P＜0.05).RT-qPCR showed that the relative mRNA expression of NL-RP3 in the NC group,CRI-L group,CRI-M group and CRI-H group was 1.004±0.005,4.004±0.716,2.027±0.303 and 0.741±0.069,respectively;the relative mRNA expression of Caspase-1 was 1.010±0.006,4.337±0.345,2.268±0.058 and 0.713±0.021,respectively;the relative mRNA expression of GSDMD was 1.000±0.000,2.938±0.559,1.955±0.166 and 1.213±0.051,respectively.Compared with the NC group,the relative expressions of NLRP3,Caspase-1 and GSDMD in the CRI-L group and CRI-M group significantly increased(all P＜0.05).The immunohistochemical staining results showed that the fluorescence intensity of NLRP3 in the retina of rats in the NC group,CRI-L group,CRI-M group and CRI-H group was 0.379 4±0.002 2,0.400 7±0.011 4,0.379 0±0.006 9 and 0.377 0±0.007 5,respectively;the fluorescence intensity of Caspase-1 was 0.367 2±0.005 8,0.442 6±0.041 1,0.382 4±0.011 9 and 0.380 6±0.006 5,respectively;the fluorescence intensity of GSDMD was 0.159 5±0.013 4,0.167 5±0.011 9,0.397 6±0.014 3 and 0.377 2±0.022 8,respec-tively.Compared with the NC group,rats in the CRI-L group showed increased fluorescence intensity of NLRP3 and Caspase-1,and rats in the CRI-M and CRI-H showed increased fluorescence intensity of GSDMD(all P＜0.05).The spec-tral comparison revealed that the CRI-H group had a broader spectral coverage and a distribution closer to natural light spectra.Conclusion Conventional LED exposure can induce a decrease in retinal thickness,upregulate the ROS expres-sion in retinal tissues,and increase the expression levels of NLRP3,Caspase-1 and GSDMD.High CRI full-spectrum LEDs can mitigate pyroptosis through the ROS/NLRP3 pathway by optimizing their spectral distribution,offering better biosafety.

Objectives:To investigate the effects of sarcopenia on the clinical efficacy of percutaneous ver-tebral augmentation(PVA)in the treatment of osteoporotic thoracolumbar vertebral compression fracture(OTLVCF).Methods:We retrospectively analyzed the clinical data of 270 patients with OTLVCF who under-went PVA in the Second Affiliated Hospital,Air Force Military Medical University and Honghui Hospital Af-filiated to Xi'an Jiaotong University from January 2020 to December 2022.There were 109 males and 161 females;T10 vertebral fracture in 37 cases,T11 fracture in 52 cases,T12 fracture in 68 cases,L1 fracture in 72 cases,and L2 fracture in 41 cases.The patients were divided into sarcopenia group(52 cases)and non-sarcopenia group(218 cases)according to the diagnostic criteria of the European Working Group on Sar-copenia in Older People(EWGSOP),and using the dominant hand grip strength(＜28.0kg)and the skeletal mus-cle index(SMI)at L3 level(＜45.4cm2/m2)in male and the dominant hand grip strength(＜18.0kg)and SMI at L3 level(＜34.4cm2/m2)in female as the diagnostic thresholds.The general data(gender,age,height,weight,body mass fraction,fracture segment,strength of grasp and skeletal muscle index),operative data(surgical method,operative time,intraoperative blood loss,bone cement injection volume and intraoperative fluoroscopy times),and complications(cement leakage,refracture of injured vertebra,refracture of the adjacent vertebra and distal vertebral refracture)after operation of both groups of patients were collected.The visual analogue scale(VAS)and Oswestry disability index(ODI)were collected before operation and on postoperative 1d,at 1 month,6 months and 1 year postoperatively and compared between the two groups.Results:There was no statistical difference in gender,height,weight,operative method,operative time,blood loss,bone cement injection vol-ume,intraoperative fluoroscopy times,and preoperative VAS score and ODI between the two groups(P＞0.05).The patients in the sarcopenia group were older(80.3±7.9 years vs 75.7±6.8 years,P＜0.05)and had a smaller BMI(24.4±2.2kg/m2 vs 26.2±2.4kg/m2,P＜0.05).The VAS score and ODI of the two groups on ld and,at 1 month,6 months and 1 year after operation were significantly improved compared with those before operation(P＜0.05).At the same time,the VAS score and ODI in the sarcopenia group were significantly higher than those in the non-sarcopenia group on ld and,at 1 month,6 months and 1 year after operation(P＜0.05).In terms of complications,there was no significant difference in the incidence of bone cement leakage between the two groups(9.65％vs 7.34％,P＜0.05).The incidence of re-fracture of injured vertebrae,adjacent vertebrae and distal vertebrae and the total incidence of re-fracture within 1 year after operation in the sarcopenia group were significantly higher than those in the non-sarcopenia group(9.62％vs 2.75％,13.46％vs 5.05％,11.54％vs 4.13％and 33.61％vs 11.93％,P＜0.05).Conclusions:The clinical effects of vertebral augmenta-tion(PVA)in patients with sarcopenia are poorer than in non-sarcopenia OTLVCF patients,with higher verte-bral re-fracture rates within 1 year after operation.

Objective:To construct an indicator system for the development of nursing disciplines in ClassⅢ Grade A general hospitals.Methods:An initial draft of the indicator system was established through literature research and expert meetings. The Delphi method and purposive sampling were used from January to April 2023 to conduct two rounds of expert consultations with 17 nursing experts from four medical units nationwide and three nursing colleges. The indicators were revised and refined, resulting in the establishment of a nursing discipline construction indicator system for ClassⅢ Grade A general hospitals. The level of expert engagement was represented by the questionnaire recovery rate, expert authority by the expert authority coefficient ( Cr), and the degree of expert opinion coordination by Kendall 's harmony coefficient (Kendall 's W) . Results:The recovery rates for both rounds of expert consultation questionnaires were 100.00% (17/17), with expert Cr of 0.87. The CV values ranged from 0.049 to 0.260 and 0 to 0.140, respectively, while Kendall 's W were 0.221 and 0.257 ( P< 0.01). The final indicator system for the construction of nursing disciplines in ClassⅢ Grade A general hospitals included six primary indicators, 18 secondary indicators, and 63 tertiary indicators. Conclusions:The nursing discipline construction indicator system developed for ClassⅢ Grade A general hospitals in this study is scientific, reliable, and comprehensive. It can provide a reference for the construction of nursing disciplines in Class Ⅲ Grade A general hospitals.
