ObjectiveTo evaluate the efficacy and safety of Xiaoji Hufei Formula in protecting children with close contact exposure to influenza， and to provide reference and evidence-based support for better clinical prevention and treatment of influenza in children. MethodsA multicenter， prospective， non-randomized， parallel， controlled trial was conducted from October 2021 to May 2022 in five hospitals， including Dongfang Hospital of Beijing University of Chinese Medicine. Confirmed influenza cases and influenza-like illness （ILI） cases were collected， and eligible children with close contact exposure to these cases were recruited in the outpatient clinics. According to whether the enrolled close contacts were willing to take Xiaoji Hufei formula for influenza prevention， they were assigned to the observation group （108 cases） or the control group （108 cases）. Follow-up visits were conducted on days 7 and 14 after enrollment. The primary outcomes were the incidence of ILI and the rate of laboratory-confirmed influenza. Secondary outcomes included traditional Chinese medicine （TCM） symptom score scale for influenza， influenza-related emergency （outpatient） visit rate， influenza hospitalization rate， and time to onset after exposure to influenza cases. ResultsA total of 216 participants were enrolled， with 108 in the observation group and 108 in the control group. Primary outcomes： （1） Incidence of ILI： The incidence was 12.0% （13/108） in the observation group and 23.1% （25/108） in the control group， with the observation group showing a significantly lower incidence （χ²=4.6， P<0.05）. （2） Influenza confirmation rate： 3.7% （4/108） in the observation group and 4.6% （5/108） in the control group， with no statistically significant difference. Secondary outcomes： （1） TCM symptom score scale： after onset， nasal congestion and runny nose scores differed significantly between the two groups （P<0.05）， while other symptoms such as fever， sore throat， and cough showed no significant differences. （2） Influenza-related emergency （outpatient） visit rate： 84.6% （11 cases） in the observation group and 96.0% （24 cases） in the control group， with no significant difference. （3） Time to onset after exposure： The median onset time after exposure to index patients was 7 days in the observation group and 4 days in the control group， with a statistically significant difference （P<0.05）. ConclusionIn previously healthy children exposed to infectious influenza cases under unprotected conditions， Xiaoji Hufei formula prophylaxis significantly reduced the incidence of ILI. Xiaoji Hufei Formula can be recommended as a specific preventive prescription for influenza in children.

OBJECTIVE: To observe the clinical efficacy of auricular electroacupuncture for post-stroke dysphagia in the pharyngeal phase. METHODS: Eighty-two patients with post-stroke dysphagia in the pharyngeal phase were randomized into an auricular electroacupuncture group (41 cases) and a swallowing electrical stimulation group (41 cases, 1 case dropped out). In the auricular electroacupuncture group, electroacupuncture was applied at auricular points, i.e. Xin (CO₁₅) and Yanhou (TG₃), using disperse-dense wave, in frequency of 2 Hz/10 Hz, 30 min a time. In the swallowing electrical stimulation group, swallowing electrical stimulation was delivered for 30 min a time. Both groups were treated once daily for 4 weeks. The functional oral intake scale (FOIS) grade, as well as the hyolaryngeal complex displacement, the pharyngeal constriction rate (PCR) and the pharyngeal delay time (PDT) under video fluoroscopic study of swallowing (VFSS) were observed before and after treatment, and the clinical efficacy was evaluated in the two groups. RESULTS: Compared before treatment, the FOIS grade was improved (P<0.01), the forward and upward displacement amplitude of hyoid bone and thyroid cartilage was increased (P<0.05), and the PCR and PDT were decreased (P<0.05) after treatment in the two groups. After treatment, compared with the swallowing electrical stimulation group, the FOIS grade was superior (P<0.01), the upward displacement amplitude of hyoid bone and thyroid cartilage was larger (P<0.05) and the PCR and PDT were lower (P<0.05) in the auricular electroacupuncture group. The total effective rate was 85.4% (35/41) in the auricular electroacupuncture group, which was higher than 62.5% (25/40) in the swallowing electrical stimulation group (P<0.05). CONCLUSION Auricular electroacupuncture can effectively trigger pharyngeal initiation and improve post-stroke dysphagia in the pharyngeal phase.

Objective:This investigation sought to delineate the associations among colorectal adenomatous polyps, diabetes, and biomolecules involved in glucose metabolism.Method:Data were collected from 40 patients who underwent endoscopic polypectomy at the Endoscopy Department of Shandong Cancer Hospital between June 2019 and September 2021. This cohort included 27 patients with inflammatory polyps and 13 with adenomatous polyps. We assessed fasting insulin (Fins), fasting blood glucose (FBG), and the mRNA expressions of fibroblast growth factor 19 (FGF-19) and insulin-like growth factor 1 (IGF-1) in the polyp tissues. Both univariate and multivariate logistic regression analyses were employed to ascertain the determinants influencing the emergence of adenomatous polyps. From these analyses, a predictive nomogram was constructed to forecast the occurrence of adenomatous polyps, and evaluations on the discriminative capacity, calibration, and clinical utility of the model were conducted.Results:The adenomatous polyp group exhibited markedly elevated levels of glucose, insulin, FGF-19, and IGF-1, with respective concentrations of (8.67±2.70) mmol/L, (12.72±7.69) μU/L, 2.20±1.88, and 1.36±0.69. These figures were significantly higher compared to the inflammatory polyp group, which showed levels of (5.51±0.72) mmol/L, (5.49±2.68) μU/L, 0.53±0.97, and 0.41±0.46, respectively, P=0.001. Multivariate logistic regression revealed that the relative expression of IGF-1 served as an independent risk factor for the development of colorectal adenomatous polyps ( OR=5.622, 95% CI:1.085-29.126). The nomogram displayed a C-index of 0.849, indicating substantial discriminative capability. The calibration curve affirmed the model's accuracy in aligning predicted probabilities with actual outcomes, and the clinical decision curve demonstrated thepractical clinical applicability of the model. Conclusions:There was a significant correlation between the occurrence of colorectal adenomatous polyps and glucose metabolic pathways. Individuals with diabetes showed a higher propensity to develop such polyps.

According to the course of disease < 180 d and ≥180 d, these patients were divided into acute brucellosis group and chronic brucellosis group, and the clinical data of the two groups of patients were compared and analyzed.Results:A total of 153 patients with brucellosis were included, including 119 in the acute brucellosis group and 34 in the chronic brucellosis group. The age was (46.2 ± 13.8) years old, with 115 males (75.2%) and 38 females (24.8%), and 85 patients (55.6%) were occupational exposed. Complications occurred in 90 patients (58.8%), and the incidence of complications in the acute brucellosis group was lower than that in the chronic brucellosis group [76.5% (26/34) vs 53.8% (64/119), χ 2 = 5.62, P = 0.018]. The most common clinical manifestations were fever and arthralgia, with 128 cases (83.7%) and 124 cases (81.0%), respectively. The incidence of fever in the acute brucellosis group was higher than that in the chronic brucellosis group [87.4% (104/119) vs 70.6% (24/34), χ 2 = 5.46, P = 0.019], while the incidence of arthralgia was lower than that in the chronic brucellosis group [77.3% (92/119) vs 94.1% (32/34), χ 2 = 4.83, P = 0.027]. In laboratory tests, the positive rate of blood culture was 59.5% (91/153), and it was higher in the acute brucellosis group than that in the chronic brucellosis group [67.2% (80/119) vs 32.4% (11/34), P < 0.05]. The incidence of elevated procalcitonin [PCT, 58.6% (58/99) vs 24.1% (7/29), χ 2 = 10.65, P = 0.001] and the incidence of liver dysfunction [33.9% (40/118) vs 15.2% (5/33), χ 2 = 4.33, P = 0.037] in the acute brucellosis group were higher than those in the chronic brucellosis group. In the imaging examination, 61 patients (39.9%) experienced bone destruction, and the incidence of bone destruction in the chronic brucellosis group was higher than that in the acute brucellosis group [55.9% (19/34) vs 35.3% (42/119), χ 2 = 4.68, P = 0.031].

Conclusions:The main clinical manifestations of brucellosis patients are fever and arthralgia, with a high incidence of complications. All patients are treated with combined antibiotics therapy. Patients in acute brucellosis group have a higher incidence of fever, positive blood culture, elevated PCT and abnormal liver function, while patients in chronic brucellosis group have a higher incidence of complications, arthralgia and bone destruction.

Objective:To evaluate the practical value of the up-converting phosphor technology (UPT) in the field fast detection of plague, and to provide scientific basis for its promotion and application in the field work of plague monitoring.Methods:In September 2020, a total of 116 samples (including 4 samples for epidemic determination) were collected at the plague epidemic site in Menghai County, Yunnan Province, including 24 human blood and lymphatic fluid samples, 83 rat liver and muscle samples, and 9 rat blood samples. In March 2023, a total of 12 rat liver and muscle samples were collected from Lijiang City for on-site monitoring of plague outbreak (all of them were outbreak determination samples). All of the above samples were tested for Yersinia pestis antibody and antigen using the up-converting phosphor technology. At the same time, haemagglutination test, real-time fluorescence quantitative PCR and bacterial culture were conducted to compare the detection process and results of different experimental methods, the advantages and disadvantages of the up-converting phosphor technology for detecting Yersinia pestis were analyzed, and the feasibility of using this detection method in the field of plague epidemic monitoring was judged. Results:The plague epidemic samples site in Menghai County, Yunnan Province were tested by up-converting phosphor technology, and 19 samples were found to be positive for Yersinia pestis (1 antibody-positive and 18 antigen-positive). Among the samples determined, 4 samples with positive results of Yersinia pestis were detected by up-converting phosphor technology, and the results of their haemagglutination test, real-time fluorescence quantitative PCR and bacterial culture were all positive. All samples from Lijiang City were tested by up-converting luminescence technology, two samples were positive for Yersinia pestis(antigen-positive). The results of haemagglutination test and real-time fluorescence quantitative PCR were positive, and one sample was positive for bacterial culture. The time required for up-converting phosphor technology, haemagglutination test, real-time fluorescence quantitative PCR, and bacterial culture were 0.5, 4.0, 2.5 and 72.0 h, respectively. Conclusions:The results of Yersinia pestis detection by up-converting phosphor technology are basically consistent with the results of haemagglutination test, real-time fluorescence quantitative PCR and bacterial culture, but the time used is relatively short. When the number of samples is large, this method can be used preferentially in the field work of plague outbreak monitoring, which can quickly complete the preliminary judgement of plague outbreak, and save a lot of time and economic resources for the next step of plague prevention and control work.

Objective To investigate the risk factors of femoral head necrosis after internal fixation of fem-oral neck fracture,and to clarify the predictive role of serological index plasminogen activator inhibitors-1(PAI-1)on femoral head necrosis.Methods A total of 95 patients undergoing internal fixation for femoral neck fracture were included in the study.Relevant clinical information of patients was obtained and the serum PAI-1 levels of the patients before surgery,1,2,and 3 days after surgery were detected.After 1-year follow-up,patients were divided into necrosis group and non-necrosis group according to the occurrence of femoral head necrosis.Visual Analog Scale(VAS),Western Ontario McMaster University Osteoarthritis Index(WOMAC),and Harris Hip Score(HHS)were conducted in all patients one year after the surgery.The differences of basic clinical information and serum PAI-1 levels before and after the surgery between necrosis group and non-necrosis group were compared,and Logistic regression analysis was performed to identify the relevant risk factors for femoral head necrosis.The relationships between the PAI-1 level after operation and the VAS,WOMAC,and HHS scores of patients were figured out.The receiver operating characteristic(ROC)curve of serum PAI-1 as a predictive indicator for femoral head necrosis was drawn to clarify its predictive val-ue.Results Garden classification and reduction quality between the necrosis group and the non-necrosis group were risk factors for femoral head necrosis(P＜0.05).The serum PAI-1 at 1 day and 2 days after surgery in the necrosis group were significantly higher than that in the non-necrosis group(P＜0.05).The level of PAI-1 at 1 day and 2 days after surgery was positively correlated with VAS and WOMAC(P＜0.05),and negative-ly correlated with HHS(P＜0.05).Logistic regression analysis showed that the increase of serum PAI-1 level at 1 day and 2 days after surgery were risk factors for femoral head necrosis(P＜0.05).The ROC curve showed that serum PAI-1 level at 2 days after surgery had higher predictive value than that at 1 day after sur-gery,and the cut-off value was 44.8 ng/L,the sensitivity was 68.49％,the specificity was 86.36％,and the ar-ea under the curve(AUC)was 0.807.Conclusion The serum PAI-1 level at 1 day and 2 days after internal fixation of femoral neck fracture could be used to predict the occurrence of femoral head necrosis,especially the serum PAI-1 levels at 2 days after surgery.

Objective To investigate the significance of intratumoral and peritumoral radiomics models in predicting occult lymph node metastasis in stage T1 non-small cell lung cancer(NSCLC)and to compare the predictive accuracy in different peritumoral radiomics models.Methods The CT images and clinical data of 211 patients without lymph node metastasis on preoperative CT examination and pathologically confirmed NSCLC after surgery were collected.The radiomics features were derived from the three-dimensional volume of interest(VOI)of the intratumoral and peritumoral at 3-,5-,and 10-mm following lesion segmentation on CT images of each patient.The feature data of all nidus were radomly divide into training set and validation set with a ratio of 7︰3.The Pearson or Spearman correlation test was performed to remove redundancy.Dimensionality was reduced by the least absolute shrinkage and selection operator(LASSO)regression analysis.The linear combination of selected features and corresponding coefficients were used to construct the Radiomics score(Radscore).The clinical model and comprehensive model were constructed by logistic regression analysis.The conprehensive model was visualized with the nomogram,and its performance was evaluated.Results Among the peritumoral radiomics models,the peritumoral 5-mm model showed the best predictive efficacy[validation set,area under the curve(AUC)0.771].The comprehensive model containing Radscore,CT image features and CEA exhibited the best performance(validation set,AUC 0.850).Conclusion Intratumoral and peritumoral radiomics models perform efficiently in predicting occult lymph node metastasis in stage T1 NSCLC,and nomogram can effectively and noninvasively predict occult lymph node metastasis in NSCLC.
