Objective To investigate the clinical characteristics of lower respiratory tract infections oc-currence and respiratory system prognosis in infantile stage of children patients with bronchopulmonary dys-plasia(BPD).Methods Fifty premature infants with lower respiratory tract infection and BPD treated in this hospital from March 2017 to December 2020 were selected as the BPD group and 50 preterm infants with low-er respiratory tract infection without BPD during the same period were selected as the non-BPD group.The clinical data and occurrence situation of respiratory system diseases within 3 years after birth in the two groups were collected and analyzed.Results Compared with the non-BPD group,the incidence rates of tachy-pnoea(48.0%vs.12.0%),wheeze(44.0%vs.10.0%),wheezing rale(44.0%vs.10.0%),three concave sign(28.0%vs.8.0%),cyanosis(20.0%vs.4.0%),severe pneumonia(48.0%vs.12.0%)and respirato-ry failure(20.0%vs.4.0%)in the BPD group were higher,the hospitalization duration[7.5(7.0,10.0)d vs.7.0(6.0,7.0)d]was longer,the reaching peak time ratio[18.20%(14.65%,22.25%)vs.24.85%(19.55%,32.78%)],the reaching peak volume ratio[22.15%(19.43%,23.83%)vs.25.65%(22.40%,34.90%)]and the inspiratory/expiratory ratio(0.70±0.12 vs.0.76±0.11)were lower,the 3-year total lower respiratory tract infection times[5.0(4.0,10.0)times vs.3.0(2.0,5.0)times],wheeze times[2.0(1.0,4.0)times vs.0.5(0,1.0)times],the hospitalization times[3.00(2.00,5.00)times vs.2.00(1.00,2.00)times],severe pneumonia times[2.0(1.0,2.0)times vs.1.0(0,1.0)times]and wheeze times in differ-ent ages were more,total hospitalization duration[29.50(19.50,38.25)d vs.13.00(7.00,17.75)d]was lon-ger,the differences were statistically significant(P<0.05).Conclusion The children patients with BPD are prone to lower respiratory tract infections,especially 0-<1 years old,the proportion of severe pneumonia af-ter infection is higher and wheezing is easily to develop.

Objective:To quickly identify the causes of morphological abnormalities of microcytic hypochromic erythrocytes that are detected during health checkups for recruitment of flying cadets, and to explore its role in medical selection.Methods:Students with hemoglobin (Hb)≥110 g/L and morphological abnormalities of microcytic hypochromic erythrocytes detected during the 2023 medical selection of flying cadets by Guangzhou Selection Center were selected. Their medical history was collected, and iron metabolism, Hb electrophoresis and hemoglobin H (HbH) inclusion bodies were examined to screen for thalassemia and iron deficiency. The diagnosis of thalassemia was confirmed by thalassemia gene testing. Those with iron deficiency received iron supplementation therapy and the recovery of Hb was observed.Results:Ninety-one students were diagnosed with Hb≥110 g/L and morphological abnormalities of microcytic hypochromic erythrocytes, accounting for 4.35% of the total. Among these cases, 85 with abnormal Hb electrophoresis and/or positive HbH inclusion body detection were confirmed as thalassemia minor via thalassemia genetic testing, and 3 cases with normal iron metabolism, Hb electrophoresis, and negative HbH inclusion body detection. A total of 88 cases of thalassemia minor were diagnosed, accounting for 96.70% of the total. Among them, 2 cases were complicated with iron deficiency while 3 were diagnosed with iron deficiency erythropoiesis. Out of the 91 students with Hb≥110 g/L and morphological abnormalities of microcytic hypochromic erythrocytes, 9 were recruited, including 7 cases with thalassemia minor (Hb≥130 g/L), 1 case with thalassemia minor combined with iron deficiency erythropoiesis (Hb≥130 g/L after iron supplementation), and 1 case with iron deficiency erythropoiesis (Hb≥130 g/L after iron supplementation). Among the 9 recruits, 8 were followed up for over one year and the results of their military physical fitness tests all reached or exceeded the standards, but the remaining one dropped out and lost contact.Conclusions:Among physical examinees during medical selection of flying cadets in South China, thalassemia is the leading cause of morphological abnormalities of microcytic hypochromic erythrocytes. Results of iron metabolism, Hb electrophoresis, and HbH inclusion body detection can help identify thalassemia and iron deficiency quickly. Cases of morphological abnormalities of microcytic hypochromic erythrocytes caused by iron deficiency can be considered eligible for selection after Hb levels return to normal following iron supplementation therapy. Students who are diagnosed with thalassemia with Hb<130 g/L can be determined as ineligible. Such rapid identification can facilitate the medical selection of the above 2 types of students.

Objective To evaluate the diagnostic value of shear wave dispersion(SWD)in preoperative assessment of liver fibrosis in patients with hepatocellular carcinoma(HCC).Methods A total of 62 patients with HCC who were admitted to the hospital between January 2022 and January 2024 were included in this study.All patients underwent shear wave elastography(SWE)examination prior to hepatectomy.The extent of liver fibrosis was assessed based on surgical and pathological findings.Patients were categorized into two groups:a low-grade fibrosis group(stages S0-S2)and a high-grade fibrosis group(stages S3-S4).Baseline characteristics and liver parenchymal SWE values were compared between the two groups.Multivariate logistic regression analysis was conducted to identify factors influencing the degree of liver fibrosis in HCC patients.The diagnostic performance of SWE in preoperative evaluation of liver fibrosis was assessed using receiver operating characteristic(ROC)curve analysis.Results Among the 62 patients with HCC,pathological results indicated that there were 11,13,20,and 18 cases in fibrosis stages S1,S2,S3,and S4,respectively.The SWD values of liver parenchyma significantly differed among patients with varying degrees of liver fibrosis.As the severity of liver fibrosis increased,the SWD of liver parenchyma also increased(P<0.05).Spearman correlation analysis revealed a positive correlation between the SWD value of liver parenchyma and the degree of liver fibrosis in preoperative HCC patients(r=0.608,P<0.05).Platelet count(PLT)was lower in the high-grade fibrosis group compared to the low-grade fibrosis group(P<0.05).Additionally,both the S index and SWD value of liver parenchyma were higher in the high-grade fibrosis group than in the low-grade fibrosis group(P<0.05).Multivariate logistic regression analysis demonstrated that the S index and SWD value were independent influencing factors for the degree of liver fibrosis in preoperative HCC patients(P<0.05).ROC curves showed that the area under the curve(AUC)of the SWD value was greater than that of the S index for assessing the degree of liver fibrosis in preoperative HCC patients(P<0.05).The cutoff value,sensitivity,and specificity of the SWD value for assessing the degree of liver fibrosis were 16.25 m/s·kHz-1,65.79%,and 95.83%,respectively.Conclusion The SWD value of liver parenchyma is closely associated with the extent of liver fibrosis in patients with HCC and provides a highly valuable assessment of the degree of liver fibrosis.

Objective:To report construction of Evidence-Based Guidelines for the Diagnosis and Treatment of Distal Radius Fractures in Adults (2024) using the Delphi method.Methods:Literature related to the study of adult distal radius fractures was fully searched for and evaluated. An expert group was established from representative experts from all over the nation. The related clinical issues were established by consulting the experts in the form of electronic questionnaires, strictly following the Delphi research method. After the first draft of Evidence-Based Guidelines for the Diagnosis and Treatment of Distal Radius Fractures in Adults (2024) was written, an expert consultation questionnaire was designed for the recommendation opinions to determine the recommendation strength.Results:The clinical issues were determined by 2 rounds of correspondence based on the Delphi method. For the both rounds of correspondence, the questionnaire recovery rates were respectively 88.68% (47/53) and 98.11% (52/53), and the expert authority coefficients >0.7. According to the screening criteria based on the importance of clinical issues (mean importance score <3.5 points or a coefficient of variation ≥0.25 points and a full score ratio <30%) and expert opinions, a total of 40 clinical issues were deleted in the first round of determination of clinical issues, and a total of 5 clinical issues deleted in the second round of determination of clinical issues. The reliability analysis of the results of the 2 rounds of questionnaires showed that the Cronbach α coefficient was >0.9. In the questionnaire to determine the recommendation strength, according to the screening criteria for the consistency of recommendation strength (consistency ≥ 70%) and expert opinions, a total of 26 recommendations were screened in the first round. In the second round when the remaining 4 recommendations were investigated, one recommendation reached the consistency of recommendation strength ≥ 70%. Eventually, 27 recommendations were formed.Conclusion:The Evidence-Based Guidelines for the Diagnosis and Treatment of Distal Radius Fractures in Adults (2024) constructed using the Delphi method shows good scientific validity, authority, and reliability, providing methodological references for guideline development and research.

Objective To apply a multidimensional neonatal nutritional risk screening scale for hospitalized premature infants to explore its predictive value for extrauterine growth restriction(EUGR)at the time of discharge.Methods A total of 104 premature infants hospitalized in the Neonatal Department of the Second Affiliated Hospital of Kunming Medical University from January 2023 to September 2023 were selected as research subjects.Nutritional risk screening was conducted within 24 hours of admission and weekly thereafter using the multidimensional neonatal nutritional risk screening scale.Scoring was based on four dimensions(birth status,weight changes,nutritional intake methods,and disease diagnosis),with a total score of ≥ 8 indicating high risk;≥4 and＜8 indicating moderate risk;and＜4 indicating low risk.EUGR at the time of discharge was the primary clinical outcome indicator.Receiver operating characteristic(ROC)curves were constructed to explore the predictive value of neonatal nutritional risk screening for EUGR in premature infants.Results At discharge,40 premature infants(38.5％)experienced EUGR.The nutritional risk screening scores of the EUGR group on day 7 of hospitalization were higher than those of the non-EUGR group(P＜0.05).The rate of high nutritional risk on day 7 of hospitalization was highest(7.9％in the non-EUGR group,22％in the EUGR group,and 13.5％overall).On both day 1 and day 7 of hospitalization,the rate of high nutritional risk in the EUGR group was higher than that in the non-EUGR group(P＜0.05).There were significant differences in the nutritional risk screening scores on day 7,birth weight Z-scores,discharge corrected gestational age weight Z-scores,and serum albumin levels between the EUGR and non-EUGR groups(P＜0.05).ROC curves were plotted,yielding AUCs of 0.625(95％CI 0.514,0.736),0.652(95％CI 0.544,0.760),0.674(95％CI 0.561,0.786),and 0.641(95％CI 0.531,0.750),indicating certain predictive value.A combined predictive ROC model yielded an AUC of 0.786(95％CI 0.692,0.880)for EUGR,which was higher than the AUCs for individual indicators(P＜0.001).Conclusion The occurrence of EUGR is relatively common among hospitalized premature infants.The nutritional risk is highest during the first week of hospitalization.The multidimensional neonatal nutritional risk screening scale can dynamically assess nutritional risk during hospitalization and may serve as one of the early warning indicators for EUGR in premature infants.The predictive efficacy for EUGR is enhanced when combined with birth weight Z-scores,discharge weight Z-scores,and serum albumin,providing a basis for individualized nutritional management of premature infants.

Objective To systematically evaluate the risk factors for new-onset atrial fibrillation (NOAF) after off-pump coronary bypass grafting (OPCABG). Methods PubMed, EMbase, Web of Science, The Cochrane Library, Wanfang data, CBM, VIP, and CNKI databases were systematically searched by computer to collect studies related to the risk factors for NOAF after OPCABG from the establishment of the database to July 2023. Literature screening and quality evaluation were conducted independently by two researchers. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the literature. RevMan 5.3 and Stata15.0 were used for meta-analysis. Results Finally, 19 case-control studies related to the risk factors for NOAF after OPCABG were included, all of which were high-quality literature with NOS score≥6 points, with a total of 7019 subjects. The results of meta-analysis showed that the following factors were associated with NOAF after OPCABG: (1) the patient’s own factors: age (MD=3.51, 95%CI 2.39 to 4.63, P<0.01); (2) preoperative factors: history of hypertension (OR=1.17, 95%CI 1.04 to 1.32, P=0.01), history of myocardial infarction (OR=1.21, 95%CI 1.06 to 1.38, P<0.01), history of percutaneous coronary intervention (OR=2.22, 95%CI 1.03 to 4.77, P=0.04), EuroSCOREⅡ score (MD=0.59, 95%CI 0.25 to 0.94, P<0.01), low-density lipoprotein (MD=0.11, 95%CI 0.02 to 0.20, P=0.02), left atrial diameter (MD=1.64, 95%CI 0.24 to 3.04, P=0.02); (3) postoperative and treatment factors: left ventricular end-diastolic diameter (MD=1.16, 95%CI 0.33 to 1.99, P<0.01), left ventricular ejection fraction (MD=0.90, 95%CI 0.07 to 1.73, P=0.03), mechanical ventilation time (MD=2.78, 95%CI 1.65 to 3.90, P<0.01), B-type natriuretic peptide (MD=219.67, 95%CI 27.46 to 411.88, P=0.03), ICU retention time (MD=7.07, 95%CI 5.64 to 8.50, P<0.01). Conclusion The existing evidence shows that age, history of hypertension, history of myocardial infarction, history of percutaneous coronary intervention, preoperative EuroSCOREⅡscore, preoperative low-density lipoprotein, preoperative left atrial diameter, postoperative left ventricular end-diastolic diameter, postoperative left ventricular ejection fraction, postoperative mechanical ventilation time, postoperative B-type natriuretic peptide, and postoperative ICU retention time are risk factors for NOAF after OPCABG. Clinical attention should be paid to the above factors to achieve early identification, thereby reducing the incidence of NOAF after OPCABG and improving the clinical prognosis of patients.

Drug repurposing offers a promising alternative to traditional drug development and significantly re-duces costs and timelines by identifying new therapeutic uses for existing drugs.However,the current approaches often rely on limited data sources and simplistic hypotheses,which restrict their ability to capture the multi-faceted nature of biological systems.This study introduces adaptive multi-view learning(AMVL),a novel methodology that integrates chemical-induced transcriptional profiles(CTPs),knowledge graph(KG)embeddings,and large language model(LLM)representations,to enhance drug repurposing predictions.AMVL incorporates an innovative similarity matrix expansion strategy and leverages multi-view learning(MVL),matrix factorization,and ensemble optimization techniques to integrate heterogeneous multi-source data.Comprehensive evaluations on benchmark datasets(Fdata-set,Cdataset,and Ydataset)and the large-scale iDrug dataset demonstrate that AMVL outperforms state-of-the-art(SOTA)methods,achieving superior accuracy in predicting drug-disease associations across multiple metrics.Literature-based validation further confirmed the model's predictive capabilities,with seven out of the top ten predictions corroborated by post-2011 evidence.To promote transparency and reproducibility,all data and codes used in this study were open-sourced,providing resources for pro-cessing CTPs,KG,and LLM-based similarity calculations,along with the complete AMVL algorithm and benchmarking procedures.By unifying diverse data modalities,AMVL offers a robust and scalable so-lution for accelerating drug discovery,fostering advancements in translational medicine and integrating multi-omics data.We aim to inspire further innovations in multi-source data integration and support the development of more precise and efficient strategies for advancing drug discovery and translational medicine.
