By systematically combing ancient and modern literature， this paper examined Tribuli Fructus and Astragali Complanati Semen（ACS） used in the famous classical formulas from the aspects of name， origin， production area， harvesting and processing， clinical efficacy， so as to provide a basis for the development of famous classical formulas containing such medicinal materials. The results showed that the names of Tribuli Fructus in the past dynasties were mostly derived from its morphology， and there were nicknames such as Baijili， Cijili and Dujili. The name of ACS in the past dynasties were mostly originated from its production areas， and there were nicknames such as Baijili， Shayuan Jili and Tongjili. Because both of them had the name of Baijili， confusion began to appear in the Song dynasty. In ancient and modern times， the main origin of Tribuli Fructus were Tribulus terrestris， and ancient literature recorded the genuine producing areas of Tribuli Fructus was Dali in Shaanxi and Tianshui in Gansu， but today it is mainly cultivated in Anhui and Shandong. The fruit is the medicinal part， harvested in autumn throughout history. There is no description of the quality of Tribuli Fructus in ancient times， and the plump， firm texture， grayish-white color is the best in modern times. Traditional processing methods for Tribuli Fructus included stir-frying and wine processing， while modern commonly used is purified， fried and salt-processed. The ancient records of Tribuli Fructus were spicy， bitter， and warm in nature， with modern research adding that it is slightly toxic. The main effects of ancient and modern times include treating wind disorders， improving vision， promoting muscle growth， and treating vitiligo. The mainstream base of ACS used throughout history is Astragalus complanatus. Ancient texts indicated ACS primarily originated from Shaanxi province. Today， the finest varieties come from Tongguan and Dali in Shaanxi. The medicinal part is the seed， traditionally harvested in autumn. Modern harvesting occurs in late autumn or early winter， followed by sun-drying. Ancient texts valued seeds with a fragrant aroma as superior， while modern standards prioritize plump， uniform and free of impurities. Traditional processing methods for ACS included frying until blackened and wine-frying， while modern practice commonly employs purification methods. In terms of medicinal properties， the ancient and modern records are sweet and warm in nature. Due to originally classified under Tribuli Fructus， its effects were thus regarded as equivalent to those of Tribuli Fructus， serving as the medicine for treating wind disorders， additional functions included tonifying the kidneys and treating vitiligo. The present record of its efficacy is to tonify the kidney and promote Yang， solidify sperm and reduce urine， nourish the liver and brighten the eye， etc. Based on the textual research results， it is suggested that when developing the famous classical formulas of Tribuli Fructus medicinal materials， we should pay attention to the specific reference object of Baijili， T. terrestris and A. complanatus should be identified and selected， and the processing method should be in accordance with the requirements of the formulas.

Objective To explore the predictive value of CT radiomics and morphological features for the prognosis and survival in non-small cell lung cancer(NSCLC)patients.Methods The clinic data of 300 NSCLC patients(300 lesions)were downloaded from the Cancer Imaging Archive,with 210 randomly selected as the training set and 90 as the test set.According to the prognosis and survival,the patients were divided into two groups with survival period≤3 and＞3 years.3D Slicer software was used to delineate the regions of interest layer by layer in CT images,and the radiomics features were extracted from each region of interest.Both t-test and least absolute shrinkage and selection operator were utilized for radiomics feature screening.Three types of prediction models,namely radiomics model,morphological model and combined model,were constructed with Logistic regression,whose performances were evaluated using the receiver operating characteristic(ROC)curve.Results The differences in radiomics labels and mediastinal lymph node metastasis between the training set and the test set were statistically significant.For radiomics model,morphological model and combined model,the area under the ROC curve was 0.784(95%CI:0.722-0.847),0.734(95%CI:0.664-0.804)and 0.748(95%CI:0.680-0.815)in the training set,and 0.737(95%CI:0.630-0.844),0.665(95%CI:0.554-0.777)and 0.687(95%CI:0.578-0.797)in the test set,which demonstrated that radiomics model had the best diagnostic performance.Conclusion The CT radiomics model can effectively predict the prognosis and survival in NSCLC patients.

Background The serious air pollution of highway toll booths poses a high occupational exposure risk to toll collectors. It is urgent to develop purification methods suitable for airborne particles and microbial pathogens in highway toll booths. Objective To verify the purification effect of low temperature plasma air purifiers on airborne particles and microbes in highway toll booths. Methods Based on controlled-intervention design, we selected three toll booths in an expressway toll station as on-site experimental locations for 6 d (no-intervention period: the low-temperature plasma purifier was turned off in the first three days; intervention period: the purifier was turned on from 9:00 to 17:00 in the following three days). The indoor and outdoor PM_2.5 and PM₁₀ concentrations were continuously monitored during the study. At 9:00, 12:00, and 17:00 of every day during the experiment, indoor and outdoor air samples were collected to analyze the concentration of airborne culturable colonies with a plankton sampler. Airborne particle samples were collected in the outermost exit continuously from 9:00 to 17:00 every day during the experiment using a medium flow particulate sampler, and the species and relative abundance of fungi and bacteria contained in the samples were analyzed by gene sequencing. Independent-sample t test was used to compare the concentration of indoor PM_2.5, PM₁₀, and culturable colonies between the intervention period and the non-intervention period. α diversity analysis, β diversity analysis, and t test were used to compare the diversity and relative abundance of specific species of bacteria and fungi, as well as typical pathogenic bacteria and fungi in the samples between the non-intervention period and the intervention period to reflect the purification effect of low temperature plasma air purifier on airborne PM_2.5, PM₁₀, and microorganisms. Results During the intervention period, the mean indoor concentrations of PM_2.5, PM₁₀, and culturable colonies were lower than those of the no-intervention period (P<0.01 or P<0.001). The ratios of indoor to outdoor concentration (I/O) of PM_2.5 and PM₁₀ during the intervention period were significantly lower than those of the no-intervention period (P<0.001), except the I/O of culturable colonies. Compared with the average concentration at 9:00, the average cleaning rates at 12:00 and 17:00 for PM_2.5 were 49.0% and 46.1%, for PM₁₀ were 49.7% and 45.4%, for airborne culturable colonies were 50.8% and 49.9%, respectively. The β diversity analysis showed that there were significant differences in composition at the level of species of bacteria, and at the levels of genus and species of fungi between the intervention and the no-intervention periods. The relative abundances of 10 species of bacteria such as Lactobacillus and 7 species of fungi such as Torula in the intervention period were significantly lower than those in the non-intervention period, but the relative abundances of fungi such as unclassified_f_cladosporiaceae, trichomerium, and cercospora were higher (P<0.05). For typical pathogenic bacteria, the relative abundances of Lactobacillus and Clostridium_sensu_stricto_1 during the intervention period were 73.5% and 86.9% lower than those in the no-intervention period, and the relative abundance of Talaromyces was 53.5% lower (P<0.05). Conclusion Low temperature plasma air purifier has a good purification effect on indoor PM_2.5, PM₁₀, and culturable colonies in highway toll booths, and likely a limited effect on some fungi.

Postoperative pulmonary complications and anastomotic leakage are unfavorable prognostic factors in patients with esophageal carcinoma.However,the prognostic importance of pulmonary complications and anastomotic leakage after neoadjuvant treatment in these patients remains unclear.This study aimed to determine the effect of postoperative pulmonary complications and anastomotic leakage on long-term survival after neoadjuvant therapy for esophageal cancer.Our study were recruited 441 consecutive patients who had curative resection following neoadjuvant treatment for esophageal cancer in our institution from 2011-2021.The clinicopathological characteristics and prognosis of these patients were studied in terms of postoperative pulmonary complications and anastomotic leaking.Survival was analyzed using the log-rank test and multivariable Cox regression analysis.Postoperative pulmonary complications and anastomotic leakage were present in 23.8％(n=105)and 5.2％(n=23)of esophageal cancer after neoadjuvant therapy,respectively.In the univariate analyses,pulmonary complications were associated with shorter disease-free survival,while anastomotic leakage was associated with shorter overall survival.Multivariable analysis revealed that pulmonary complications after neoadjuvant therapy were independent adverse prognostic factors for disease-free survival.Taken together,postoperative pulmonary complications and anastomotic leakage ware significantly negatively correlated with disease-free and overall survival,respectively.And the postoperative pulmonary complication is an independent poor prognostic factor of disease-free survival for esophageal cancer following neoadjuvant treatment.

Background and objective With further understanding and research into non-small cell lung cancer with tumours ≤2 cm in maximum diameter,segmental lung resection is able to achieve the same long-term prognosis as lobec-tomy.However,there are few studies on the prognostic effect of wedge resection on small volume invasive lung adenocarci-noma with an invasion depth of 0.5 to 1.0 cm.Therefore,this study focuses on the clinical efficacy and prognosis of wedge re-section in patients with small-volume invasive lung adenocarcinoma.Methods A retrospective analysis of the medical records of 208 patients who underwent surgery in the Department of Thoracic Surgery of the Affiliated Provincial Hospital of Anhui Medical University from February 2016 to December 2017 was made,and the postoperative pathological results confirmed small volume invasive lung adenocarcinoma.According to their surgical methods,they were divided into lobectomy group(n=115),segmentectomy group(n=48)and wedge resection group(n=45).Kaplan-Meier survival curve estimation and Cox proportional risk regression model were used to explore the influence of different surgical methods on the prognosis of patients with small volume invasive lung adenocarcinoma.Results The wedge resection group had better perioperative outcomes compared with the segmentectomy group and lobectomy group,with statistically significant differences in intraoperative bleed-ing(P=0.036),postoperative drainage(P＜0.001),operative time(P=0.018),postoperative time with tubes(P=0.001),and postoperative complication rate(P=0.006).There were no significant differences when comparing the three groups in terms of survival rate(lobectomy group vs segmentectomy group,P=0.303;lobectomy group vs wedge resection group,P=0.742;and segmentectomy group vs wedge resection group,P=0.278)and recurrence-free survival rate(lobectomy group vs segmentec-tomy group,P=0.495;lobectomy group vs wedge resection group,P=0.362;segmentectomy group vs wedge resection group,P=0.775).Univariate and multivariate survival analyses showed that consolidation tumor ratio(CTR)was the prognostic factor of overall survival and revurrence-free survival for patients with small-volume invasive lung adenocarcinoma(P＜0.05).Conclusion Wedge resection in patients with small volume invasive lung adenocarcinoma can achieve long-term outcomes similar to segmentectomy and lobectomy.When the CTR≤0.5,wedge resection is preferred in such patients.

Background/Aims: Previous studies have shown that diet and physical activity can influence constipation. However, the combined effect of diet and physical activity on constipation remains unclear. Methods: Constipation was defined based on stool consistency and frequency, while overall diet quality was assessed using Healthy Eating Index (HEI)-2015 scores. Participants were categorized into low (metabolic equivalent [MET]-min/wk < 500) and high physical activitygroups (MET-min/wk ≥ 500). The association between diet and constipation across physical activity groups was analyzed using surveylogistic regression and restricted cubic splines. Results: Higher HEI-2015 scores were associated with reduced constipation risk in the high physical activity group when constipation was defined by stool consistency (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.97-0.99). However, in the low physical activity group, increased HEI-2015 scores did not significantly affect constipation risk (OR, 1.01; 95% CI, 0.97-1.05). Similar results were found when constipation was defined based on stool frequency. In the high physical activity group, increased HEI-2015 scores were significantly associated with a reduced constipation risk (OR, 0.96; 95% CI, 0.94-0.98). Conversely, in the low physical activity group, increased HEI-2015 scores did not affect the risk of constipation (OR, 0.96; 95% CI, 0.90-1.03). Conclusions Our findings suggest that a higher HEI-2015 score is negatively associated with constipation among individuals with high physical activity levels but not among those with low physical activity levels. This association was consistent when different definitions of constipation were used. These results highlight the importance of combining healthy diet with regular physical activity to alleviate constipation.

Objective:To explore the application effect of massive open online course (MOOC) combined with peer mutual assistance in cardiopulmonary resuscitation teaching.Methods:A total of 140 students in the same class of Batch 2015 were divided into the experimental group and the control group. In the teaching of cardiopulmonary resuscitation, the experimental group was based on the MOOC teaching platform, watched videos and topic tests before class, and used the peer mutual assistance in class. While the control group adopted traditional classroom teaching mode. The teaching effect of the two groups were evaluated by comparing the operation assessment scores and questionnaire survey of students' satisfaction with teaching. SPSS 22.0 was used for t-test and Chi-square test. Results:The operating assessment score of the experimental group was (82.20±2.31), and the operating assessment score of the control group was (75.80±1.72). The difference was statistically significant ( t=3.27, P<0.05). The questionnaire survey showed that the course satisfaction and learning motivation of the experimental group were better than those of the control group. In learning burden, the two groups had similar results ( P=0.739). Conclusion:MOOC combined with peer mutual assistance in cardiopulmonary resuscitation teaching can help students better master skills, improve students' course satisfaction and learning motivation, without increasing their learning burden.

Objective:To develop and examine the reliability and validity of the adolescent health literacy evaluation scale under public health emergencies (AHLES-PHE) in junior middle school students.Methods:The initial version of AHLES-PHE was formed by combining the characteristics of public health emergencies and adolescent health literacy.The expert version of AHLES-PHE was formed by two rounds of Delphi expert consultation.Totally 1 729 adolescent students from three junior middle schools in Changzhou City were tested.The formal version of AHLES-PHE was formed through item analysis and factor analysis (structural validity). The content validity of the formal version of AHLES-PHE was evaluated by specialist analysis and sensibility analysis, and its correlation validity with the everyday health information literacy (EHIL) was tested.The internal consistency reliability, parity split-half coefficient and test-retest reliability were calculated.Results:(1)Item analysis: the correlation coefficient between the scores of each item and the total score of AHLES-PHE expert version was 0.420 to 0.722 ( P<0.01), and the CR of decision value was 10.140 to 66.980 ( P<0.01). (2)Validity analysis: the formal version of AHLES-PHE with 45 items and 8 factors was obtained by exploratory factor analysis.The 8 factors could explain 61.30% of the total variation.The fitting indexes of the confirmatory factor analysis model were χ2/ df=3.325, RMSEA=0.052, GFI=0.853, CFI=0.912, TLI=0.904, NFI=0.880.Sensibility analysis of the formal version of AHLES-PHE showed the Cronbach's α ranged from 0.957 to 0.958.The correlation coefficient between the total score of AHLES-PHE formal version and the total score of EHIL was 0.340 ( P<0.01). (3)Reliability analysis: the Cronbach's α coefficient and parity split-half coefficient of the formal version of AHLES-PHE were 0.958 and 0.975, respectively.The test-retest reliability of the formal version of AHLES-PHE was 0.753 ( P<0.01). Conclusion:The formal version of AHLES-PHE developed in this study has good reliability, structural validity and content validity, and the correlation validity with EHIL is common.This scale has a certain degree of applicability to the assessment of health literacy for junior middle school students under public health emergencies.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.
