Objective To mine and analyze the routine blood test data of children with allergic rhinitis (AR), identify routine blood parameters related to childhood allergic rhinitis, establish an effective diagnostic model, and evaluate the performance of the model. Methods This study was a retrospective study of clinical cases. The experimental group comprised a total of 1110 children diagnosed with AR at the First Affiliated Hospital of Air Force Medical University during the period from December 12, 2020 to December 12, 2021, while the control group included 1109 children without a history of allergic rhinitis or other allergic diseases who underwent routine physical examinations during the same period. Information such as age, sex and routine blood test results was collected for all subjects. The levels of routine blood test indicators were compared between AR children and healthy children using comprehensive intelligent baseline analysis, with indicators of P≥0.05 excluded; variables were screened by Lasso regression. Binary Logistic regression was used to further evaluate the influence of multiple routine blood indexes on the results. Five kinds of machine model algorithms were used, namely extreme value gradient lift (XGBoost), logistic regression (LR), gradient lift decision tree (LGBMC), Random forest (RF) and adaptive lift algorithm (AdaBoost), to establish the diagnostic models. The receiver operating characteristic (ROC) curve was used to screen the optimal model. The best LightGBM algorithm was used to build an online patient risk assessment tool for clinical application. Results Statistically significant differences were observed between the AR group and the control group in the following routine blood test indicators: mean cellular hemoglobin concentration (MCHC), hemoglobin (HGB), absolute value of basophils (BASO), absolute value of eosinophils (EOS), large platelet ratio (P-LCR), mean platelet volume (MPV), platelet distribution width (PDW), platelet count (PLT), absolute values of leukocyte neutrophil (W-LCC), leukocyte monocyte (W-MCC), leukocyte lymphocyte (W-SCC), and age. Lasso regression identified these variables as important predictors, and binary Logistic regression further analyzed the significant influence of these variables on the results. The optimal machine learning algorithm LightGBM was used to establish a multi-index joint detection model. The model showed robust prediction performance in the training set, with AUC values of 0.8512 and 0.8103 in the internal validation set. Conclusion The identified routine blood parameters can be used as potential biomarkers for early diagnosis and risk assessment of AR, which can improve the accuracy and efficiency of diagnosis. The established model provides scientific basis for more accurate diagnostic tools and personalized prevention strategies. Future studies should prospectively validate these findings and explore their applicability in other related diseases.

Objective To search for and verify the genetic factors that lead to familial thoracic aortic aneurysm and dissection.Methods Patients with a family history were screened from clinical cases of thoracic aortic aneurysm and dissection,and their relevant clinical data were collected.After extracting the whole-genome DNA from the proband's blood samples,gene panel testing was carried out,and first-generation sequencing was used to verify the blood samples of the proband's immediate and collateral relatives.Meanwhile,relevant cell experiments were designed.First,the ACTA2-Leu195 * point mutation plasmid was constructed,and then the mutant plasmid and wild-type ACTA 2 were transfected into cells through expression plasmids respectively.After 48 hours,RNA and total protein were extracted,and the expression levels were detected by qPCR and Western blotting,respectively.Results Through high-throughput sequencing,the mutation site of c.583delC in the ACTA2 gene was found,and it was also confirmed that the heterozygous mutation at this site in the family was closely related to familial thoracic aortic aneurysm and dissection.The results of cell experiments showed that the mRNA and protein expression levels in the group transfected with the ACTA2-Leu195 * mutant plasmid were significantly decreased compared with those of the wild type,suggesting that the mutant could not express proteins normally.Conclusion Through clinical family studies and cell-level experiments,a new mutation site in ACTA2 leading to familial thoracic aortic aneurysm and dissection has been discovered,which provides a new approach for the screening,detection and clinical treatment of familial thoracic aortic aneurysm and dissection.

AIM:To evaluate the safety and toler-ability of single dose oral BTK inhibitor YZJ-3058 tablets under fasting conditions in healthy adults,as well as the pharmacokinetic and pharmacologi-cal characteristics of YZJ-3058 and its metabolites.METHODS:A total of 22 healthy subjects were en-rolled in this experiment and administered a single dose orally.They were divided into three groups:50 mg,100 mg,and 200 mg.Among them,2 sub-jects were enrolled in the 50 mg dose group,and 10 subjects were enrolled in the 100 mg and 200 mg dose groups,respectively.RESULTS:In healthy subjects,YZJ-3058 tablets were administered orally on an empty stomach at doses of 50,100,and 200 mg,with a median Tmax of 1.25 to 2.00 hours and an average Cmax of 62.85,89.44,and 99.20 ng/mL,re-spectively.The average AUC0-t was 183.87,297.72,and 453.98 h·ng-1·mL,respectively.The average AUC0-∞ was 189.30,321.33,and 551.44 h·ng-1·mL,and the median t1/2 was 1.16,5.06,and 7.97 hours,respectively.After a single oral administration of 50,100,and 200 mg YZJ-3058 tablets,the highest target occupancy rate was achieved at 4 hours.The average BTK occupancy rates at 24 hours after ad-ministration were 88.95％,96.73％,and 99.24％,re-spectively.The average BTK occupancy rates at 48 hours after administration were 75.65％,89.80％,and 96.68％,respectively.No serious adverse events or adverse events leading to withdrawal oc-curred,and all subjects had good tolerability.CON-CLUSION:YZJ-3058 tablets have good safety and tolerability for single oral administration on an empty stomach in healthy subjects within the dose range of 50-200 mg.Cmax and AUC increase with dose,with fast absorption and saturation.The ter-minal elimination rate gradually slows down with dose increase,and it has a significant and sus-tained occupying effect on BTK targets.

Objective:To compare the safety, number of lymph nodes removed, rate of lymph node metastasis, and prognosis between proximal gastrectomy (PG) and total gastrectomy (TG) in patients with Siewert types II and III adenocarcinoma of the esophagogastric junction.Methods:In this retrospective cohort study, clinical data of patients diagnosed with adenocarcinoma of the esophagogastric junction at Changzhi People's Hospital, affiliated with Changzhi Medical College, between December 2019 and November 2022, were collected. Patients who had received neoadjuvant therapy, had multiple malignant lesions in the stomach, had concomitant malignancies in other organs, had incomplete clinical data, or had been lost to follow-up were excluded. The study cohort comprised 308 patients, 99 in the PG group and 209 in the TG group. To reduce confounding bias, propensity score matching was performed, matching patients for age, sex, body mass index, tumor diameter, and pathological stage in a 1:1 ratio, resulting in 73 patients in each group. The primary outcomes assessed were operative details, number of lymph nodes dissected, rate of lymph node metastasis, postoperative complications, duration of hospital stay, and follow-up and survival outcomes.Results:The PG group had a significantly shorter median operative time than did the TG group (250 vs. 280 minutes, Z = -4.970, P<0.001), with fewer cases of intraoperative blood loss >100 mL (30.1%[22/73] vs. 46.6%[34/73], χ2=4.171, P=0.041), and a smaller number of lymph nodes removed (median 33 vs. 46, Z =-4.774, P<0.001); all of these differences are statistically significant (all P<0.05). Differences between the two groups in postoperative hospital stay and postoperative complications were not statistically significant (both P>0.05). Furthermore, no statistically significant differences were found between the PG and TG groups in the number of lymph nodes dissected or the lymph node metastasis rates at stations No. 1, No. 2, No. 3, No. 4sa, No. 4sb, and No. 7 (all P> 0.05). Among the 209 patients in the TG group, analysis of risk factors for metastasis to distal perigastric lymph nodes (No.4d, No.5, and No.6) showed that patients with tumor diameters ≤4 cm and T1–T3 stage disease had significantly lower rates of metastasis to these lymph nodes than did patients with tumor diameters >4 cm and/or T4 stage disease (0/78 vs. 12/131 [9.2%]); these differences are statistically significant ( P=0.014). The median duration of follow-up for the entire cohort was 26 months. The 3-year overall survival rates for the PG and TG groups were 62.5% and 63.3%, respectively; this difference is not statistically significant (χ 2=0.330, P = 0.565). Multivariate analysis showed that older age ( P = 0.035) and advanced pathological stage ( P = 0.018) were significant independent risk factors that affected overall survival in patients with Siewert type II and III adenocarcinoma of the esophagogastric junction. Conclusions:PG is safe and feasible for patients with Siewert types II and III adenocarcinoma of the esophagogastric junction. The number of lymph nodes dissected and metastasis status were similar in the TG and PG groups.

Objective To investigate the effect of locking plate combined with cortical screw internal fixation on ankle function and quality of life in patients with ankle fracture with tibiofibular separation.Methods A total of 120 patients with ankle fracture and distal tibiofibular separation treated in our hospital from May 2020 to December 2021 were selected and divided into control group and observation group according to random number table method,with 60 patients/group.The control group was treated with cortical screw fixation alone,and the observation group was treated with locking plate combined with cortical screw internal fixation.Before surgery and 6 months after surgery,the recovery function of the two groups was compared.X-ray,operation duration,healing time,intraoperative blood loss,postoperative complications were compared,and the living ability of the two groups of patients was evaluated.Results Before treatment,there was no difference in joint function between the two groups(P＞0.05).After treatment,the longest walking of the control group(15.89±0.85),foot alignment(15.06±0.71),pain response(29.03±4.48)and ground walking(15.65±0.59).The longest walking distance(16.19±0.87),foot alignment(15.29±0.76),pain response(31.24±4.55)and ground walking(15.96±0.68)in the observation group,which were higher than those in control group(P＜0.05).Compared with the control group,the intraoperative blood loss and healing time in the observation group were lower(P＜0.05).BI index of the two groups before treatment had no difference(P＞0.05);After treatment,BI index of observation group was higher than that of control group(P＜0.05).There was no difference in the total complication rate between the two groups(P＞0.05).Conclusion Locking plate combined with cortical screw internal fixation has a good therapeutic effect on improving ankle function,reducing intraoperative blood loss,promoting healing and improving behavioral ability in the treatment of ankle fracture combined with hypotibiofibular syndesmosis injury.

A 27-year-old male was admitted to the Xijing Hospital in August 2018 due to unprovoked severe thoracodynia with palpitations, shortness of breath and chest tightness. Computed tomography angiography showed a type A aortic dissection. Genetic testing based on next-generation sequencing for 15 genes associated with hereditary aortic diseases and Sanger sequencing validation revealed a heterozygous missense mutation c.998G>T (p.Gly333Val) in the COL3A1 gene. Sanger sequencing verification of family members confirmed that the mutation c.998G>T co-segregated with the patient′s phenotype in this family. That mutation was classified as "likely pathogenic" according to American College of Medical Genetics and Genomics standards and guidelines for genetic variant classification. Carriers of this mutation can be definitively diagnosed with "vascular Ehlers-Danlos syndrome". After the diagnosis was clarified, symptomatic treatment was given to the patient, but the disease progressed rapidly. The patient discontinued treatment and died shortly after being discharged. In this study, we found a new variant in the COL3A1 gene, expanding the mutation spectrum of this gene.

OBJECTIVE: To analyze the outcome indexes of randomized controlled trials (RCTs) of acupuncture and moxibustion for mild cognitive impairment (MCI) so as to provide a reference for the protocol design and the construction of a core outcome set in relevant clinical trials of acupuncture and moxibustion for MCI. METHODS: From CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, EMbase, and Web of Science, RCTs of acupuncture and moxibustion for MCI were searched, and the time duration was ranged from January 1st, 2018 to October 31th, 2023. The general information and outcome indexes of the included studies were collected and analyzed through literature screening and data extraction. RESULTS: A total of 46 studies were eligible, with 2 072 samples and 18 diagnostic criteria involved. The outcome indexes were categorized into 7 domains according to functional attributes, including clinical symptoms/signs, TCM symptoms/syndromes, physical and chemical examination, quality of life, psychiatric and mental health, safety assessment, and patient satisfaction. Eighty-four outcome indexes were reported, with the use frequency of 237. Currently, RCTs of acupuncture and moxibustion for MCI were limited in the big difference in neuropsychological assessment tool, the inadequate reports on educational degree/educational years, the diversity of physical and chemical detection indexes, the inconsistency of the time points for outcome evaluation, the insufficient application of primary and secondary outcomes, the lack of the application of TCM diagnosis, pattern/syndrome differentiation and outcomes, and the shortage in long-term prognosis and economic assessment. CONCLUSION It is recommended to specify and develop the core outcome set of acupuncture and moxibustion for MCI to advance the standardization of related research design, the rational selection of outcome indexes, and the reliability of the research results.
