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.

A previous study showed that the length of the foreskin plays a role in the risk of sexually transmitted infections and chronic prostatitis, which can lead to poor quality of sexual life. Here, the association between foreskin length and sexual dysfunction was evaluated. A total of 5700 participants were recruited from the andrology clinic at The First Affiliated Hospital of University of Science and Technology of China (Hefei, China). Clinical characteristics, including foreskin length, were collected, and sexual function was assessed by the International Index of Erectile Function-5 (IIEF-5) and Premature Ejaculation Diagnostic Tool (PEDT) questionnaires. Men with sexual dysfunction were more likely to have redundant foreskin than men without sexual dysfunction. Among the 2721 erectile dysfunction (ED) patients and 1064 premature ejaculation (PE) patients, 301 (11.1%) ED patients and 135 (12.7%) PE patients had redundant foreskin, respectively. Men in the PE group were more likely to have redundant foreskin than men in the non-PE group ( P = 0.004). Logistic regression analyses revealed that the presence of redundant foreskin was associated with increased odds of moderate/severe ED (adjusted odds ratio [aOR] = 1.31, adjusted P = 0.04), moderate PE (aOR = 1.38, adjusted P = 0.02), and probable PE (aOR = 1.37, adjusted P = 0.03) after adjusting for confounding variables. Our study revealed a positive correlation between the presence of redundant foreskin and the risk of sexual dysfunction, especially in PE patients. Assessment of the length of the foreskin during routine clinical diagnosis may provide information for patients with sexual dysfunction.

The presence of 4-aminophenol(4-AP)in wastewater from the pharmaceutical industry is a common occurrence due to its role as a byproduct or intermediate during the hydrolysis process of paracetamol metabolism,resulting in significant water pollution.Therefore,it is crucial to employ a straightforward and reliable analytical approach for detecting 4-AP in the environment.In this study,a specific type of metal-organic framework(MOF)material called[Cd4(ABTC)2(H2O)12]n(SXNU-4-Cd,H4ABTC=3,3′,5,5′-azobenzene tetracarboxylic acid)was successfully synthesized,which exhibited a unique two-dimensional layered structure consisting of three intertwined spiral chains forming a distinctive″twist braid″.These layers underwent π-π stacking,creating three-dimensional channels with azo bonds decorating the channel walls.This p-π interaction significantly enhanced the adsorption capacity of SXNU-4-Cd towards 4-AP,thereby improving its recognition sensitivity.The fabricated SXNU-4-Cd/GCE sensor showed high sensitivity towards 4-AP in the linear concentration range of 0.1-130 μmol/L,with a detection limit of 8.6 nmol/L,and also exhibited good anti-interference capability,reproducibility and stability.The SXNU-4-Cd/GCE sensor was successfully used for detecting 4-AP in lake water sample,with spiked recoveries of 95.9%-102.8%.This study introduced a novel technique that utilized pure Cd-MOFs to develop electrochemical sensor capable of effectively detecting 4-AP in water samples.

Objective To explore the predictive value of inflammatory markers for stroke-associated pneumonia(SAP)in patients with acute ischemic stroke(AIS)based on the nomogram model.Methods According to whether pneumonia occurred,259 AIS patients were divided into SAP group(81 cases)and non-SAP group(178 cases).The clinical data of the two groups were compared.The systemic inflammatory response index(SIRI),systemic immunoinflammatory index(SII)and neutrophil to lymphocyte ratio(NLR)were calculated according to the formula.The variables with statistically significant differences were included in the multivariate binary Logistic regression model to screen out the independent risk factors for SAP in AIS patients.The independent risk factors were used to construct a predictive model,and the predictive ability of the two models,which only included traditional factors and included inflammatory indicators at the same time,was further compared from the aspects of discrimination,calibration,clinical practicability and so on.Reclassification analysis was used to evaluate the extent to which the nomogram model improved the predictive value of SAP risk in AIS patients.Results Compared with those in the non-SAP group,the rates of smoking,diabetes,dysphagia,leukocytes,neutrophils,lymphocytes,triglyceride level,NIHSS score on admission,SIRI,SII and NLR were significantly increased in the SAP group,and the rate of hypertension was decreased(all P＜0.05).Diabetes mellitus(OR =2.505,95%CI:1.070-5.850,P =0.034),dysphagia(OR =3.492,95%CI:1.501-8.119,P =0.004),NIHSS score on admission(OR = 1.310,95%CI:1.188-1.446,P＜0.001),SIRI(OR =2.417,95%CI:1.327-4.401,P =0.008),NLR(OR =1.434,95%CI:1.101-1.860,P =0.007)were independent risk factors for SAP in AIS patients.The area under the curve was 0.788(95%CI:0.725-0.852,P＜0.001)for the prediction model without inflammatory factors and 0.884(95%CI:0.838-0.930,P＜0.001)for the prediction model with independent risk factors.The calibration curve showed a good consistency between the predicted risk and the observed results.The decision curve showed that the model had a significant net benefit for predicting SAP.In addition,by calculating the net reclassification index(NRI)and the comprehensive discriminant improvement index(IDI),it was found that the nomogram model had a significant improvement in predicting the risk of SAP in AIS patients.Internal verification also proves the reliability of the nomogram model.Conclusions SIRI and NLR are independent predictors of SAP in AIS patients on admission.Adding SIRI and NLR to the traditional model can significantly improve the ability to identify the risk of SAP occurrence in AIS patients.

Objective:To investigate the relationship between the expressions of checkpoint with forkhead-associated and ring finger(CHFR)and metastasis-associated protein 1(MACC1)and the sensitivity of patients with rectal cancer for neoadjuvant concurrent chemoradiotherapy(nCRT).Methods:The medical documents of 166 patients with rectal cancer admitted to First Hospital of Qinhuangdao from March 2017 to February 2022 were collected.All patients only received nCRT before surgery,and the radiotherapy adopted three-dimensional conformal intensity modulated radiotherapy,and chemotherapy adopted Capeox scheme.All patients successfully completed total mesorectal excision after 4-6 weeks of nCRT treatment.Immunohistochemical SP staining method was used to detect the protein expressions of CHFR and MACC1 in rectal cancer and its adjacent tissues.According to the tumor regressive grading(TRG)standard of the Joint Committee on Cancer Staging in the United States,75 patients who were grade 0-2 as TRG after nCRT were included in the nCRT insensitive group,and 91 patients who were grade 3-4 as TRG were included in the nCRT sensitive group.The expression levels of CHFR and MACC1 proteins in cancer tissues before and after treatment between the two groups were compared.And then,the relationship between clinically pathological characteristics of patients and nCRT sensitivity was analyzed,and the influencing factors of nCRT sensitivity were analyzed.The receiver operating characteristic(ROC)curves of them were drawn,and area under curve(AUC)values were calculated,and the predictive values of CHFR and MACC1 for the sensitivity of patients with rectal cancer to nCRT were further analyzed.Results:The CHFR positive expression rate in rectal cancer tissue was significantly lower than that in adjacent tissues of rectal cancer,and the MACC1 positive expression rate in rectal cancer tissue was significantly higher than that in adjacent tissues of rectal cancer(x2=81.373,87.150,P＜0.05),respectively.After 166 patients completed the nCRT treatment,there were 6 cases of TRG grade 0,8 cases of TRG grade 1,61 cases of TRG grade 2,59 cases of TRG grade 3 and 32 cases of TRG grade 4.The sensitivity rate of nCRT was 54.82%(91/166).The CHFR positive expression rate in the nCRT sensitive group was significantly higher than that in the nCRT insensitive group,and the MACC1 positive expression rate in the nCRT sensitive group was significantly lower than that in the nCRT insensitive group(x2=4.613,37.509,P＜0.05).The proportions of T4 stage and N+stage in the nCRT sensitive group were higher than those in the nCRT insensitive group,and the differences were statistically significant(x2=54.432,28.912,P＜0.05),respectively.The expressions of CHFR and MACC1 were respectively independent risk factor affected the sensitivity of patients with rectal cancer to nCRT[OR=2.456(95% CI:1.294-4.563),OR=3.281(95% CI:1.472-6.479),P＜0.05].The sensitivity and specificity of the combined detection of CHFR and MACC1 were respectively 65.89% and 69.46% in predicting the nCRT sensitivity for rectal cancer.The predictive value of the combined detection was higher than that of single CHFR detection and single MACC1 detection(AUC values of them were respectively 0.713,0.564,0.589,P＜0.05),respectively.Conclusion:CHFR and MACC1 are related to the sensitivity of patients with rectal cancer to nCRT,which means patients with high expression of CHFR and low expression of MACC1 are more sensitive to nCRT.Therefore,both of them may be indicators that predict the sensitivity of patients with rectal cancer to nCRT.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective To explore the efficacy of Krackow locking loop technique combined with the modified Kessler suture technique in the treatment of acute closed Achilles tendon rupture.Methods From January 2020 to January 2022,162 cases of acute closed Achilles tendon rupture were treated with Krackow locking loop technique combined with the modified Kessler suture technique.The patients were treated with the same postoperative rehabilitation plans.The American Orthopaedic Foot and Ankle Society(AOFAS)hindfoot score and Achilles Tendon Total Rupture Score(ATRS)were collected to evaluate the functions.Results The operation time was 24-40 min(mean,31.9±4.6 min).All incisions healed in one stage without infection or sural nerve injury.Complications occurred in 2 patients,including 1 case of deep venous thrombosis and 1 case of trauma-related re-rupture.The recovery time of ankle flexion and extension motion was4-12 weeks(mean,7.6±1.9 weeks),the recovery time of single-legged heel rise height on the affected side was 10-18 weeks(mean,13.3±1.8 weeks),and the recovery time of fast walking or jogging was 14-26 weeks(mean,19.1±1.8 weeks).The 162 patients was followed up for 14-25 months(mean,19.0 months).The AOFAS hindfoot score increased from(54.4±4.4)points preoperatively to(98.0±4.0)points at the last follow-up(t =-104.402,P =0.000).The ATRS score increased from(52.0±8.3)points preoperatively to(91.2±2.4)points at the last follow-up(t =-62.823,P = 0.000).Conclusions For young and middle-aged patients with acute closed Achilles tendon rupture,Krackow locking loop technique combined with the modified Kessler suture technique can achieve good clinical outcomes.Early functional exercise is required to return to work and life.

Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease with unclear etiology and limited treatment options. The median survival time for IPF patients is approximately 2-3 years and there is no effective intervention to treat IPF other than lung transplantation. As important components of lung tissue, endothelial cells (ECs) are associated with pulmonary diseases. However, the role of endothelial dysfunction in pulmonary fibrosis (PF) is incompletely understood. Sphingosine-1-phosphate receptor 1 (S1PR1) is a G protein-coupled receptor highly expressed in lung ECs. Its expression is markedly reduced in patients with IPF. Herein, we generated an endothelial-conditional S1pr1 knockout mouse model which exhibited inflammation and fibrosis with or without bleomycin (BLM) challenge. Selective activation of S1PR1 with an S1PR1 agonist, IMMH002, exerted a potent therapeutic effect in mice with bleomycin-induced fibrosis by protecting the integrity of the endothelial barrier. These results suggest that S1PR1 might be a promising drug target for IPF therapy.
