ObjectiveTo systematically evaluate the application of narrative education in undergraduate nursing teaching， to understand the current application status of narrative education， and to provide a theoretical basis for the subsequent establishment of a sound narrative education system. MethodsA systematic search was conducted for studies published in Chinese and English databases on applying narrative education to undergraduate nursing teaching， with the search period ranging from database inception to February 23， 2025. Literature was screened， and relevant information was extracted. A rigorous quality evaluation was conducted on the included studies， and a descriptive analysis was performed on their content. ResultsA total of 20 papers were included， involving 3，180 research subjects， all of whom were undergraduate nursing students. The results of descriptive analysis showed that the teaching model of narrative education primarily encompassed reading narrative works， watching films and videos， performing narrative scenarios， and writing reflective journals. The course setting and content covered pre-teaching preparation and in-teaching implementation. The evaluation of teaching effectiveness included the evaluation of teachers’ teaching methods （student evaluation/self-evaluation） and the evaluation of students’ learning effectiveness （course grade evaluation/humanistic care scale/empathy scale assessment， and others）. ConclusionNarrative education combines abstract concepts with concrete clinical situations， which not only enriches students’ learning experiences but also enhances their humanistic literacy. Meanwhile， it provides teachers with opportunities to develop their narrative teaching skills， which requires them to possess profound professional knowledge and employ narrative techniques to guide students in reflection and critical thinking， thereby improving teaching quality and learning outcomes. Future efforts should consistently deepen the connotation research of narrative education and build a systematic nursing education system.

To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

Triptolide （TP）， the core active component of the traditional Chinese medicine Tripterygium wilfordii ， exhibits remarkable pharmacological activities including anti-inflammatory， immunosuppressive and anti-tumor effects， and holds broad application prospects in the treatment of major diseases such as autoimmune diseases and malignant tumors. However， TP has a narrow therapeutic window and causes multi-organ toxicities including liver， kidney and reproductive toxicities， which severely restrict its safe clinical application and new drug development. Therefore， toxicity reduction and efficacy enhancement has become a core scientific problem urgently to be solved in this field. This paper systematically reviews the four core strategies for TP toxicity reduction and efficacy enhancement， including structural modification， dosage form improvement， herbal compatibility， and external therapies of traditional Chinese medicine. Among them， structural modification optimizes the toxic and efficacy characteristics of TP from the molecular structure level， with typica l derivatives including （5 R ）-5-hydroxy triptolide， ZT01， PG490-88， etc. Dosage form modification achieves toxicity reduction and efficacy enhancement via targeted and sustained-controlled drug release of diverse delivery systems. It includes triptolide preparations such as nanoparticles， liposomes， microemulsion gels and liquid crystals， possessing favorable clinical transformation potential. The herbal compatibility and external therapies of traditional Chinese medicine conform to the holistic view of traditional Chinese medicine and have a profound clinical application foundation， but their mechanisms of action are insufficiently elucidated， and they lack unified standardized specifications and high-quality evidence-based proof. In the future， we should rely on multi-omics technology to elucidate the toxic and efficacy mechanisms， integrate technologies to optimize preparations， improve the evaluation system and promote clinical transformation.

ObjectiveTo evaluate the clinical efficacy and safety of Xiaozhen Formula （消疹方） in preventing skin toxicity induced by epidermal growth factor receptor inhibitors （EGFRIs） in patients with EGFR-mutant non-small cell lung cancer （NSCLC）. MethodsA randomized， double-blind， placebo-controlled， multicenter clinical study was conducted. A total of 120 patients with EGFR-mutant NSCLC from seven centers were enrolled and randomly assigned to a treatment group （60 cases） or a control group （60 cases）. On the basis of EGFRI-targeted therapy， patients in the treatment group received Xiaozhen Formula granules， whereas those in the control group received Xiaozhen Formula placebo granules， both at 10 g twice daily for 4 consecutive weeks. The primary outcomes were the grading of skin toxicity evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events （NCI-CTCAE） version 5.0 and the incidence of rash. Secondary outcomes included the time to onset and time to resolution of the highest-grade rash， the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 （EORTC QLQ-C30） scores， the Hospital Anxiety and Depression Scale （HADS） scores， and disease control rate， together with safety assessments. ResultsBased on the full analysis set （FAS）， the incidence of skin toxicity in the treatment group was 18.33% （11/60）， significantly lower than 45.00% （27/60） in the control group （P＜0.01）， with the highest severity of skin toxicity in both groups was grade 2. Among patients who developed rash， the resolution rate in the treatment group was 90.91% （10/11）， higher than that 33.33% （9/27） in the control group. The median time to resolution was 15 days （95%CI： 8-17 days） in the treatment group and it was not reached in the control group； the distribution of time to resolution differed significantly between groups （P＜0.001）. After treatment， the treatment group had higher EORTC QLQ-C30 functional scale and global health status/quality-of-life scores， and lower symptom scale， single-item scores， as well as HADS-A， and HADS-D scores than the control group （P＜0.05）. In the FAS analysis， the disease control rate （DCR） was 85.0% （51/60） in the treatment group， lower than 100.0% （60/60） in the control group （P=0.003）， whereas no significant between-group difference was observed in the per-protocol set （PPS） analysis （P=0.464）. The incidence of adverse events did not differ significantly between the two groups （P＞0.05）， and no definite safety signals related to the investigational drug were observed. ConclusionXiaozhen Formula can reduce the incidence of EGFRI-induced skin toxicity， and improve the outcome of rash regression， the patients' quality of life and psychological status in EGFR-mutant NSCLC patients.

Objectives:The ORION-18 study has demonstrated that inclisiran can significantly reduce low-density lipoprotein cholesterol(LDL-C)and has good safety in Asian atherosclerotic cardiovascular disease(ASCVD)patients or ASCVD high-risk population.This subgroup analysis aims to further evaluate the efficacy and safety of inclisiran in Chinese mainland population.Methods:ORION-18 study is a multi-center,randomized,double-blind,placebo-controlled,phase Ⅲ clinical trial among Asian subjects,Chinese mainland subgroup included 232 ASCVD patients or ASCVD high-risk subjects who had already been treated with diet control and maximum tolerated doses of statins treatment(with or without other lipid-lowering treatments)but still had elevated LDL-C levels.Subjects were randomized in a 1:1 ratio to the inclisiran group and the placebo group(n=116 each),and received 300 mg of inclisiran or placebo respectively on day 0,90 and 270.The primary endpoint was the percentage change in LDL-C from baseline to day 330.The secondary endpoints included the time-adjusted percentage change and absolute change in LDL-C from baseline after day 90 and up to day 360,the absolute change in LDL-C from baseline to day 330,and the percentage changes from baseline to day 330 in proprotein convertase subtilisin/kexin type 9(PCSK9),total cholesterol,apolipoprotein B(ApoB),non-high-density lipoprotein cholesterol(non-HDL-C).Other secondary endpoints included the proportion of participants reaching LDL-C levels of<1.8 mmol/L at day 330,the proportion of participants with≥50%LDL-C reduction from baseline to day 330 and the proportion of participants who attained global lipid targets(the LDL-C target was<1.4 mmol/L for ASCVD patients and<1.8 mmol/L for ASCVD high-risk subjects)at day 330.Safety endpoints included adverse events during treatment,aboratory test abnormalities during treatment,serious adverse events,and assessed their severity and relation to treatment.Results:The inclisiran group showed a placebo-corrected percentage change in LDL-C from baseline to day 330 of-61.16%,and an absolute change of-1.73 mmol/L(both P<0.0001).Compared to the placebo group,the inclisiran group's time-adjusted percentage change in LDL-C from baseline between day 90 and day 360 was-58.51%,and an absolute change of was-1.64 mmol/L(both P<0.0001).At day 330,reductions from baseline were observed in the inclisiran group for PCSK9,total cholesterol,ApoB,non-HDL-C,with placebo-corrected percentage changes of-77.44%,-35.65%,-43.43%,-50.90%(all P<0.0001),respectively.At day 330,79.6%(74/93)of patients in the inclisiran group and 7.8%(6/77)in the placebo group achieved LDL-C levels<1.8 mmol/L,69.9%(65/93)of patients in the inclisiran group and 0%(0/77)in the placebo group achieved≥50%LDL-C reduction from baseline,66.7%(62/93)of patients in the inclisiran group and 2.6%(2/77)in the placebo group achieved their global LDL-C targets.The safety profile of inclisiran treatment over 12 months was comparable to that of the placebo,with no occurrence of treatment-related serious adverse events.Conclusions:In ASCVD patients or ASCVD high-risk subjects in Chinese mainland who have received diet control and maximum tolerable dose statins treatment(with or without other lipid-lowering treatments)and still have elevated LDL-C,inclisiran has a definite efficacy and good safety in reducing LDL-C.The efficacy and safety results of inclisiran assessed in Chinese mainland population are consistent with those of the general Asia population.

Objective To observe the origin and course of the obturator artery(OA),so as to provide anatomical reference for reducing hemorrhage during pelvic surgery and pubic fracture fixation.Methods A total of 65 human hemi-pelvises specimens with intact structure were dissected to observe the origin,course and other variations of OA.Measure the length of the inner section of OA basin and the outer diameter at the origin,etc.Results OA originated from the internal iliac artery in 57 cases(87.7%),including 3 cases(4.6%)of the superior gluteal artery,5 cases(7.7%)of the inferior gluteal artery,3 cases(4.6%)of the external iliac artery and 5 cases(7.7%)of the inferior epigastric artery.OA participated in the formation of the arterial trunk in 3 cases(4.6%).The length of the pelvic segment of the OA in male and female was(50.87±15.41)mm and(51.71±14.19)mm,respectively,with no statistically significant difference between them(P>0.05).The outer diameters at the origin of the OA in male and female were(2.79±1.05)mm and(2.35±0.86)mm,and there was no statistically significant difference between them(P>0.05).Conclusion OA mainly originated from the anterior trunk of the internal iliac artery,with a few OA originated from the branches of the posterior trunk or the inferior epigastric artery,or participated in the formation of the arterial trunk.In pelvic surgery involving OA area,attention should be paid to the length of its pelvic segment and the outer diameter at the origin of OA,so as to better locate and protect blood vessels during surgery.

Objective To investigate the comparative efficacy of different frequencies of pelvic floor electrical stimulation(PFES)on stress urinary incontinence(SUI)in rats.Methods Twenty female Sprague-Dawley rats were randomly divided into 6,15,30 and 50 Hz group by random number table method.All rats underwent vaginal dilatation(VD)to simulate postpartum SUI.One week after VD,the sneeze test was conducted to determine whether the modeling was successful.If the sneeze test was positive,the modeling was successful.The miniature and wireless electric pelvic floor stimulator were implanted into the pelvic floor muscle of the modeled rats,and PFES were treated for 2 weeks in each group at the rates of 6,15,30 and 50 Hz,respectively.The Leak point pressure(LPP)of all rats before VD,1 week after VD and 2 weeks after stimulation were measured by cystometrograms(CMGs)for comparison.Results LPP was significantly reduced in all groups of rats after VD 1 week(P<0.001).Compared with after VD 1 week,after two consecutive weeks of PFES at four different frequencies of 6,15,30 and 50 Hz,LPP was again significantly increased(P<0.001)and reached the baseline level(P>0.05)in all groups of rats.In the between-group comparison of the rats in each group,there was no significant difference in their LPP at baseline value,after VD 1 week and after stimulation 2 weeks(P>0.05).Conclusion The present study suggests that of the several stimulation frequencies explored so far,6 Hz may be a more appropriate choice for PFES.Further studies are still needed to evaluate more frequencies and the long-term efficacy of PFES.

Objective To investigate the correlation between serum levels of microRNA(miR)-489-3p and miR-214-3p in patients with Psoriasis and the severity of disease.Methods From March 2022 to January 2024,138 Psoriasis patients who visited Zhangjiakou First Hospital were regarded as the study subjects(disease group).According to the psoriasis area and severity index(PASI)score,the 138 Psoriasis patients were separated into mild group(n=46),moderate group(n=54)and severe group(n=38).112 healthy individuals who underwent physical examinations in Zhangjiakou First Hospital during the same period were included in the control group.Real-time fluorescence quantitative PCR(RT-qPCR)method was applied to determine the serum levels of miR-489-3p and miR-214-3p in the subjects.The serum levels of miR-489-3p and miR-214-3p were compared between the disease group and the control group,and among patients with different degrees of disease.Spearman correlation analysis was applied to explore the relationship between serum miR-489-3p,miR-214-3p levels and disease severity in Psoriasis patients.Logistic regression analysis was performed to analyze the related factors affecting the severity of Psoriasis.Receiver operating characteristic(ROC)curve was applied to investigate the diagnostic value of serum miR-489-3p and miR-214-3p levels for severe Psoriasis.Results The serum levels of miR-489-3p(0.81±0.23)and miR-214-3p(0.79±0.22)in the disease group were lower than those in the control group(1.05±0.28,1.02±0.25),and the differences were statistically significant(t=7.441,7.732,all P<0.05).Serum miR-489-3p in mild,moderate and severe Psoriasis groups(0.93±0.24,0.80±0.23,0.69±0.22),miR-214-3p levels(0.91±0.24,0.77±0.22,0.66±0.21)decreased gradually,and the differences were statistically significant(F=12.423,13.168,all P<0.05).Spearman's results showed that serum levels of miR-489-3p and miR-214-3p were negatively correlated with the severity of Psoriasis in patients(r=-0.490,-0.463,all P<0.05).Serum miR-489-3p and miR-214-3p were independent protective factors for the severity of Psoriasis patients(Wald χ2=5.751,8.753,all P<0.05).ROC curve results showed that the area under the curve(AUC)of serum miR-489-3p and miR-214-3p for diagnosing severe Psoriasis alone was 0.785 and 0.792,with sensitivity of 78.9%and 73.7%,specificity of 49.9%and 54.7%,respectively.The AUC of the combined diagnosis for severe Psoriasis was 0.931,the sensitivity and specificity were 71.7%,71.1%,respectively,and the combined diagnostic efficacy of the two was better than that of miR-489-3p and miR-214-3p alone,and the differences were statistically significant(Z=3.018,2.773,all P<0.05).Conclusion The serum levels of miR-489-3p and miR-214-3p in patients with Psoriasis are both reduced,and both are negatively correlated with the severity of the disease in Psoriasis patients.The combined determination of the two has high efficacy in the diagnosis of severe Psoriasis.

Objective To explore the correlation between serum circularRNA-HOMER1(circHOMER1),microRNA(miR)-23a-3p levels with clinical stages and oxidative stress in patients with diabetic retinopathy(DR).Methods From January 2023 to July 2024,75 DR patients treated in Handan Central Hospital were included as the DR group.According to the clinical staging of DR,they were divided into non proliferative DR(NPDR group,n=43)and proliferative DR(PDR group,n=32).In addition,75 patients with simple type 2 diabetes who came to Handan Central Hospital were included as non DR group.The levels of serum circHOMER1,miR-23a-3p,malondialdehyde(MDA),superoxide dismutase(SOD),and reduced glutathione(GSH)were detect-ed.Clinical data of the subjects were collected.The TargetScan website was used to predict the targeting relationship between circHOMER1 and miR-23a-3p.Pearson method was used to analyze the correlation between serum circHOMER1,miR-23a-3p and MDA,SOD,GSH.Univariate and multivariate Logistic regression were used to analyze the influencing factors of progression of DR in type 2 diabetes patients.Receiver operating characteristic(ROC)carve was used to analyze the predictive value of serum circHOMER1 and miR-23a-3p in the progression of DR in patients with type 2 diabetes.Results There was a targeted relationship between circHOMER1 and miR-23a-3p.The serum MDA(28.66±4.52ng/ml)and circHOMER1(1.24±0.16)levels in the DR group were higher than those in the non DR group(16.95±3.27ng/ml,1.02±0.11),while SOD(45.39±7.84U/L),GSH(135.82±21.23μg/mL)and miR-23a-3p(0.88±0.07)levels were lower than those in the non DR group(81.65±11.47U/L,207.44±25.95μg/mL,1.01±0.09),and differences were statistically significant(t=9.813～22.602,all P<0.001).The serum MDA(33.28±4.96ng/ml)and circHOMER1(1.36±0.20)levels in the PDR group were higher than those in the NPDR group(25.23±3.58ng/ml,1.15±0.17),while SOD(34.39±7.15U/L),GSH(113.50±20.17μg/ml)and miR-23a-3p(0.79±0.07)levels were lower than those in the NPDR group(53.27±8.44U/L,152.43±23.99μg/ml,0.94±0.08),and the differences were statistically significant(t=4.906～10.376,all P<0.001).Spearman analysis showed that serum MDA and circHOMER1 were positively correlated with the severity of DR(r=0.533,0.473,all P<0.001),while SOD,GSH,miR-23a-3p were negatively correlated with the severity of DR(r=-0.552,-0.515,-0.529,all P<0.001).Pearson analysis showed that serum circHOMER1 was negatively correlated with miR-23a-3p,SOD,GSH,and positively correlated with MDA(r=-0.475,-0.460,-0.455,0.462,all P<0.001).Serum miR-23a-3p was positively correlated with SOD and GSH,and negatively correlated with MDA(r=0.428,0.437,-0.439,all P<0.001).Logistic regression analysis showed that high MDA,low SOD,low GSH,high circHOMER1,low miR-23a-3p,high FPG and high HbA1c were the risk factors of progression of DR in type 2 diabetes patients(OR=0.214～3.556,all P<0.05).The area under curve(AUC)of serum circHOMER1 and miR-23a-3p alone and jointhy predicting the progression of DR in type 2 diabetes patients were 0.751,0.797 and 0.903 respectively.The combined prediction was higher than that of serum circHOMER1 and miR-23a-3p alone(Z=3.179,2.335,P=0.002,0.020).Conclusion Serum MDA and circHOMER1 levels are higher in DR patients,while serum SOD,GSH and miR-23a-3p levels are lower.Abnormal expression of circHOMER1 and miR-23a-3p in serum is associated with progression of DR and oxidative stress.Combined detection of circHOMER1 and miR-23a-3p in serum can predict the progression of DR in patients with type 2 diabetes.

Objective:To compare the types and contents of trace elements in compound trace element preparations used in parenteral nutrition in Beijing against the doses recommended by the guidelines, so as to facilitate optimal choice of preparations for different populations in clinical practice.Methods:The available compound trace element preparations were determined according to the drug list from the Medical Insurance Recruitment and Procurement System of Beijing and the recommended doses of trace elements in the guidelines released by Chinese domestic and foreign nutrition societies were collected and compared.Results:The compound trace element preparations used in Beijing comprised 4 varieties and 6 specifications, with the daily cost ranging from 11.32 to 471 Chinese Yuan. There were 3 varieties of trace element preparations for adults, including multi-trace elements injection (Ⅱ), multi-trace elements injection (Ⅲ), and multi-trace elements injection. Among those, multi-trace elements injection (Ⅲ) met the guideline recommendations best and the price was moderate. For pediatric populations, multi-trace elements injections (Ⅰ) satisfied better the trace element requirements for preterm infants and infants from term to 3 months, while multi-trace elements injections (Ⅲ) outperformed in meeting the trace element requirements for 3-to-12-month infants and children. However, there were still some differences in the trace element contents between the two preparations and the guideline recommendations.Conclusion:The currently available varieties and specifications of trace element preparations basically meet the recommendations of evidence-based guidelines, but there is still the need to improve the instructions for and evidence on the pediatric application of certain preparations.
