OBJECTIVE To develope a predictive model for medication deviation risks during the hospital-to-home transition period in coronary heart disease （CHD） patients with initial treatment， aiming to assist medical staff in rapidly identifying high-risk groups for medication deviation. METHODS A total of 462 CHD patients with initial treatment from the Affiliated Hospital of North China University of Science and Technology （hereinafter referred to as “our hospital”） between January and July 2024 were enrolled. The patients were randomly divided into a modeling group and an internal validation group. The modeling group was further categorized into a medication deviation group and a non-medication deviation group based on whether medication deviations occurred. Similarly， 57 CHD patients with initial treatment from the cardiology department of our hospital between June and September 2025 were collected as an external validation group. Univariate analysis was used to screen predictive factors， followed by multivariate Logistic regression to construct the predictive model. Internal validation methods were employed to evaluate model performance， while external validation methods were used to test the model’s generalizability. RESULTS The 462 patients were divided into a modeling group （319 cases） and an internal validation group （143 cases）. In the modeling group， the medication deviation group （192 cases， 60.19%） and the non-medication deviation group （127 cases， 39.81%） were identified. Multivariate Logistic regression analysis revealed that age， medication type， medication adherence， and self-efficacy in rational medication use were predictive factors for medication deviations in CHD patients with initial treatment （ P ＜0.05）. The predictive model equation was logit P ＝ln[ P /（1－ P ） ] ＝1.321+1.732×age+4.091×medication type －4.360×medication adherence －3.081×self-efficacy in rational medication use. The model demonstrated good discrimination， with a Hosmer-Lemeshow goodness-of-fit test P -value of 0.439， an area under the receiver operating characteristic curve （AUC） of 0.870， sensitivity of 0.970， and specificity of 0.607. A risk nomogram with a total score of 350 points and a cutoff value of 110 points was plotted. The internal validation group showed an AUC o f 0.787 and a prediction accuracy of 77.6%， while the external validation group exhibited an AUC of 0.802 and a prediction accuracy of 73.7%. CONCLUSIONS This study successfully developed a predictive model for medication deviation risks during the hospital-to-home transition period in CHD patients with initial treatment. The model demonstrates excellent discrimination and predictive accuracy， effectively identifying high-risk populations for medication deviations. Age （＞70 years）， number of drug types≥5， poor medication adherence， and poor self-efficacy in rational medication use are independent risk factors for medication deviations.

OBJECTIVES: To investigate the effect of orexin-A-mediated regulation of ionotropic glutamate receptors for promoting motor function recovery in rats with spinal cord injury (SCI). METHODS: Thirty-six newborn SD rats (aged 7-14 days) were randomized into 6 groups (n=6), including a normal control group, a sham-operated group, and 4 SCI groups with daily intrathecal injection of saline, DNQX, orexin-A, or orexin-A+DNQX for 3 consecutive days after PCI. Motor function of the rats were evaluated using blood-brain barrier (BBB) score and inclined plane test 1 day before and at 1, 3, and 7 days after SCI. For patch-clamp experiment, spinal cord slices from newborn rats in the control, sham-operated, SCI, and SCI+orexin groups were prepared, and ventral horn neurons were acutely isolated to determine the reversal potential and dynamic indicators of glutamate receptor-mediated currents under glutamate perfusion. RESULTS: At 3 and 7 days after SCI, the orexin-A-treated rats showed significantly higher BBB scores and grip tilt angles than those with other interventions. Compared with those treated with DNQX alone, the rats receiving the combined treatment with orexin and DNQX had significantly higher BBB scores and grip tilt angles on day 7 after PCI. In the patch-clamp experiment, the ventral horn neurons from SCI rat models exhibited obviously higher reversal potential and greater rise slope of glutamate current with shorter decay time than those from sham-operated and orexin-treated rats. CONCLUSIONS Orexin-A promotes motor function recovery in rats after SCI possibly by improving the function of the ionotropic glutamate receptors.

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.

BackgroundChildhood represents a critical stage for cognitive development. Accurate assessment of children's cognitive abilities and understanding their developmental characteristics are essential for promoting healthy growth. However， traditional cognitive assessment methods typically rely on manual administration， presenting limitations such as low efficiency and insufficient engagement. These methods struggle to meet the assessment needs of children and are difficult to scale up for large-scale applications. ObjectiveTo develop a digital cognitive assessment tool for children， so as to provide a more convenient approach for evaluating children's cognitive functions. MethodsBased on classic psychological paradigms （Stroop Task， N-back， digit span， spatial orientation， and face-name matching）， a digital cognitive assessment tool was developed. This tool includes five tasks including color matching， shape matching， greening the home， great collector， and face-name matching， designed to assess core cognitive functions such as inhibitory control， working memory， short-term memory， spatial orientation， and semantic processing， respectively. From August 2024 to March 2025， a total of 750 students aged 9–12 yeas old from a primary school in Chengdu were enrolled and assessed using the digital cognitive assessment tool. Three months later， 40 children were randomly selected for retesting using both the digital tool and its corresponding standardized psychological paradigms. Pearson correlation analysis was conducted to examine the correlation between the pre-test and retest scores of the digital cognitive assessment tool， as well as the correlation between the digital cognitive task scores and the corresponding psychological paradigm assessment results， in order to evaluate the reliability and validity of the digital cognitive assessment tool. Additionally， differences in scores across the cognitive tasks were compared among children of different age groups and genders. ResultsA total of 699 valid samples were included. The younger age group consisted of children aged 9–10 years old （n=460）， while the older age group comprised those aged 11–12 years old （n=239）. There were 356 boys （50.93%） and 343 girls （49.07%）. In the reliability analysis， the Pearson correlation coefficients between the pre-test and retest scores of each assessment task ranged from 0.732 to 0.970 （P<0.01）， indicating statistically significant results. In the validity analysis， the Pearson correlation coefficients between each task and its corresponding standard cognitive test ranged from 0.679 to 0.988 （P<0.01）. In the color-matching task， both the main effects of age and gender were statistically significant （F=31.071， 21.198， P<0.01）. In the shape-matching task， the main effects of age， gender， and their interaction were all statistically significant （F=20.933， 5.926， 4.318， P<0.05 or 0.01）. In the greening the home task， the main effect of age was significant （F=5.243， P=0.023）. In the great collector task， the main effect of age was significant （F=33.697， P<0.01）. In the face-name matching task， only the main effect of gender was significant （F=27.016， P<0.01）. Further analysis showed that within the female group， older group scored significantly higher than younger group in five tasks（P<0.05 or 0.01）. Within the male group， younger group scored lower than older group in both the color-matching and great collector tasks （P<0.05 or 0.01）. Within the younger group， boys scored significantly higher than girls in color-matching and shape-matching tasks （P<0.01）. In the older group， girls scored significantly higher than boys in face-name matching task （P<0.01）. ConclusionThe digital cognitive assessment tool developed in this study demonstrates good reliability and validity. The development of cognitive functions in children aged 9–12 years old showed significant differences in age and gender， with specific developmental trajectories across different cognitive dimensions. At younger ages， boys outperformed girls in inhibitory control and working memory tasks， though this advantage diminished with age. At older ages， girls exhibited superior performance in semantic processing compared with boys.

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.

Objective To investigate the effect of polymyxin B(PMB)combined with tigecycline(TGC)on delaying Klebsiella pneumoniae(KP)resistance to PMB,and to analyze the possible mechanisms involved in the induction and delay of resistance.Methods Six clinical isolates of KP strains from the Intensive Care Unit of First Affiliated Hospital of Army Medical University were subjected and then induced with PMB at 1/2 minimal inhibitory concentration(MIC)alone or combined with TGC at 1/2 and 1/4 MIC,respectively.The MIC changes of PMB in these strains were monitored over 14 consecutive passages.The strain 686K,which showed the most significant delay in resistance,was selected for further analysis.Differences in gene and protein expression were examined among the wild-type strain 686K,PMB-induced resistant strain(686K·R),and PMB combined with TGC delayed resistant strain(686K·DR)using transcriptome sequencing,qRT-PCR,and proteomics.Relevant target genes during the delay of resistance were analyzed through literature and bioinformatics analyses.Additionally,cpxR gene knockout strain 686K/ΔcpxR∷Apr and its complementation strain 686K/ΔcpxR∷Apr/pRK415-cpxR were constructed using homologous recombination technology to assess the expression levels of resistance-related genes and changes in MIC after induction in vitro.Results Under sub-MIC(1/2)PMB alone,resistance developed in all 6 KP strains within 2 d,while,the combination with TGC significantly delayed the development of resistance.Transcriptomic and proteomic analyses indicated that in strain 686K·R,the expression levels of the PhoP/Q two-component system,lipopolysaccharide(LPS)modification enzymes,and efflux pump systems were significantly up-regulated(|Log2FC|≥2,P<0.0001),while TGC co-administration markedly inhibited these expression changes.The cpxR deletion and complementation strains were successfully constructed.The expression levels of resistance-related genes phoP,pmrD,and acrA were decreased in the cpxR deletion strain(P<0.001),and the resistance was delayed until day 6 under PMB monotherapy,whereas the complementation strain restored the resistance phenotype by day 2.In the absence of cpxR,the effect of PMB when combined with TGC on delaying resistance did not differ from that observed with PMB monotherapy.Conclusion The combination of PMB and TGC can delay KP resistance to PMB.cpxR,as a critical regulatory factor,can impact PMB resistance by modulating LPS modifications and the expression of the AcrAB-TolC efflux pump,and plays an important regulatory role in the process of resistance induction.

Serotonin syndrome (SS), also known as serotonin toxicity, is a rare but life-threatening drug reaction syndrome. This case involves a 17-year-old female patient who developed tremors, fatigue, and tachycardia after taking fluoxetine combined with bupropion and tandospirone for five days. SS was highly suspected, and her symptoms improved following treatment targeted at serotonin syndrome. This case is reported to raise awareness among clinicians about the potential adverse reactions of drug combinations, the importance of early identification of SS symptoms, and precautions when prescribing combined medications to avoid serious consequences.

Objective To investigate the clinical efficacy of oblique lumbar interbody fusion(OLIF)combined with lateral plate fixation in the treatment of single-level adjacent segment disease(ASDis)following lumbar fusion surgery so as to evaluate the safety and effectiveness of this surgical approach.Methods A retrospective analysis was conducted on 46 patients with single-level ASDis after lumbar fusion surgery from August 2022 to October 2024.Twenty-three patients underwent OLIF combined with lateral plate fixation(OLIF group),while 23 patients received posterior lumbar interbody fusion(PLIF)(PLIF group).The following parameters were compared between the two groups:operative time,intraoperative blood loss,visual analogue scale(VAS)for pain,Oswestry disability index(ODI),disc height(DH),intervertebral foramen height(IFH),and interbody fusion status.Results All the 46 patients successfully completed surgery for single-level ASDis and were followed up for(13.7±1.1)months.The OLIF group had significantly shorter operative time[(70.7±4.6)min vs.(128.6±12.0)min]and less intraoperative blood loss[(58.6±5.7)mL vs.(313.3±47.5)mL]compared to the PLIF group(all P＜0.05).Both groups showed significant improvements in postoperative lumbar VAS and ODI scores at all follow-up time points compared to preoperative values(P＜0.05).The OLIF group exhibited significantly lower lumbar VAS scores at 3 days and 3 months postoperatively than those of the PLIF group(P＜0.05),and there was no statistical difference in VAS scores at the other follow-up time points(P＞0.05).There was no significant difference in postoperative ODI between OLIF group and PLIF group at each time point(P＞0.05).Postoperative DH and IFH were significantly improved in both groups compared to preoperative measurements(P＜0.05).In OLIF group,1 case of transient left thigh numbness resolved with conservative treatment within 2 weeks;1 case of cage subsidence was observed at 1 month postoperatively,achieving fusion without further displacement by 13 months.All the OLIF cases achieved complete fusion(fusion rate:100％).In PLIF group,2 cases of cerebrospinal fluid leakage healed with bed rest,1 case of wound exudation resolved with intensive dressing changes,and 1 case failed to achieve fusion(fusion rate:96％).Conclusion OLIF combined with lateral plate fixation demonstrates satisfactory early clinical outcomes for single-level ASDis after lumbar fusion,with significant advantages in operative efficiency(shorter time plus reduced blood loss)and short-term pain relief.Therefore,it is a safe and effective surgical approach.

OBJECTIVE To establish HPLC fingerprints of three drying processes(Atmospheric pressure drying,Decompression drying,Freeze-drying)of Danggui Buxue granules,and combine them with antioxidant tests to determine the optimal drying process and main active components of Danggui Buxue granules.METHODS The fingerprints of multiple batches of Danggui Buxue granules were established by HPLC;the"Fingerprint Similarity Evaluation System of Traditional Chinese Medicine Chromatogram"was used to evaluate the similarity;Hierarchical Cluster Analysis(HCA)and Principal Component Analysis(PCA)were used to characterize the different drying processes of Danggui Buxue granules;evaluate the antioxidant activity of Danggui Buxue granules in different drying processes using 1,1-diphenyl-2-picrylhydrazy(DPPH)and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)diammonium salt(ABTS)free radical scavenging method;the spectrum-effect relationship between Danggui Buxue granules fingerprint and antioxi-dant activity was analyzed by grey correlation degree and Pearson,Spearman,Kendall's tau-b correlation analysis methods.RE-SULTS The results of fingerprint showed that there were 16 common peaks in 30 batches of Danggui Buxue granules,and 6 of them were identified by comparison.The results of Cluster Analysis and Principal Component Analysis showed that 30 batches of Danggui buxue granules were divided into 3 categories,and the difference between the groups of atmospheric pressure drying was the least.The results of oxidation test showed that different drying processes of Danggui Buxue granules had good antioxidant activity,and the atmos-pheric pressure drying had the lowest IC50 and the strongest antioxidant activity.Finally,combining the results of gray correlation anal-ysis and correlation analysis,the compounds F2,F10,F13(calycosin),F15(formononetin),F16 might be important characteristic peaks reflecting the antioxidant activity of Danggui Buxue granules.CONCLUSION Compared with other drying processes,atmos-pheric pressure drying has higher batch consistency and stronger antioxidant activity,and can be used as the preferred drying process for Danggui Buxue granules,and components 2,10,13,15 and 16 are the main active ingredients for Danggui Buxue granules to exert antioxidant effects.
