OBJECTIVE To systematically evaluate the quality of the Heat-clearing and symptom-relieving formula and screen potential marker components that influence the quality of the formula. METHODS The contents of 11 components （calycosin-7- O - β -D-glucoside， ononin， hyperoside， isoquercitrin， baicalin， baicalein， cryptotanshinone， tanshinone Ⅱ A ， tanshinone Ⅰ， senkyunolide A， ferulic acid） in the Heat-clearing and symptom-relieving formula were determined by high-performance liquid chromatography-tandem mass spectrometry （HPLC-MS/MS）. Using the contents of the aforementioned components as variables， cluster analysis （CA）， principal component analysis （PCA）， and orthogonal partial least squares-discriminant analysis （OPLS-DA） were conducted using OriginPro 2024 software and SIMCA 14.1 software； marker components affecting the quality of the Heat-clearing and symptom-relieving formula were then screened based on the criteria of variable importance in the projection （VIP） value＞1 and P ＜0.05. The comprehensive evaluation of 20 batches of samples was carried out using the entropy weight-technique for order preference by similarity to ideal solution（TOPSIS） and grey correlation analysis （GCA） methods. RESULTS The contents of the above 11 components were 7.993-72.866， 4.542-31.228， 727.666-1 901.884， 496.846-1 293.279， 1 995.501-6 779.150， 54.500-241.280， 150.302-304.339， 79.698-189.206， 257.118-682.418， 5.498-21.687， 7.524-26.935 μg/g. CA， PCA and OPLS-DA results showed that 20 batches of samples were grouped into 2 categories. Q1， Q3， Q4， Q7-Q9， Q12， Q15， Q16 were grouped into one category， and the rest were grouped into another category； VIP values of ferulic acid， tanshinone Ⅱ A ， baicalin， cryptotanshinone， calycosin-7- O - β -D-glucoside and ononin were all greater than 1 （ P ＜0.05）. Both the entropy weight-TOPSIS and GCA methods showed that the samples ranked in the top 11 according to the euclidean distance and relative correlation degree were Q2， Q5， Q6， Q10， Q11， Q13， Q14， Q17-Q20. CONCLUSIONS The established HPLC-MS/MS method is rapid， accurate and highly sens itive. Combined with chemical pattern recognition analysis， entropy weight-TOPSIS and GCA methods， this method can be used to evaluate the quality of the Heat-clearing and symptom-relieving formula. Ferulic acid， tanshinone Ⅱ A ， baicalin， cryptotanshinone， calycosin-7- O - β -D-glucoside and ononin may be the marker components that affect the quality of this formula. The overall quality of 11 batches of the Heat-clearing and symptom-relieving formula， including Q17， is relatively superior.

Background/Aims: Non-pharmacological treatments are crucial for managing irritable bowel syndrome (IBS), yet patient engagement remains a challenge. Understanding patients' knowledge, attitudes, and practices regarding these treatments is essential for improving care. Methods: A cross-sectional study was conducted across 5 hospitals, from October 2023 to February 2024. A self-designed knowledge, attitudes, and practices questionnaire along with the IBS quality of life and IBS severity scoring system was administered, and 496 valid responses were analyzed. Statistical analyses included correlation tests, multivariate linear regression, and mediation effect analysis. Results: The median scores for knowledge, attitude, and practice were 28, 25.5, and 21, respectively. Significant positive correlations were found between knowledge-attitude (r = 0.195), knowledge-practice (r = 0.364), and attitude-practice (r = 0.151). The multivariate linear regression analysis further indicated that knowledge (β = 0.399, P < 0.001) and attitude (β = 0.219, P = 0.022) positively correlated with the practical performance. SEM revealed that knowledge had a significant direct effect on both attitude (β = 0.186, P = 0.013) and practice (β = 0.356, P = 0.006). However, the direct effect of attitude on practice was not significant, and attitude did not mediate the relationship between knowledge and practice. Conclusions IBS patients exhibit a significant gap between their positive attitudes and their actual practices concerning non-pharmacological treatments. Knowledge is a direct driver of practice, but positive attitudes alone are insufficient to translate into behavior. Healthcare providers must move beyond simply fostering positive attitudes and focus on targeted educational interventions that provide actionable knowledge and skills to improve patient outcomes.

The child, male,11 years old, Han nationality, student of Qiandongnan Miao Autonomous Prefecture, Guizhou Province, visited the General Hospital of Hunan Medical University on October 1,2024 due to“cough, chest tightness for 10 days and pericardial effusion was found for 8 days.”The child has a history of eating raw crabs. Admission examination: shortness of breath, slightly cyanotic lips, mild trifoveal symptoms, low heart sound, and routine blood showed significant eosinophil elevation. Serological examination showed that pulmonary fluke antibody IgG was positive, chest and abdomen CT and cardiac ultrasound showed a large amount of pericardial effusion, medium pleural effusion on the right side with lower right lung insufficiency, small pleural effusion on the left side, small effusion on the abdominal cavity, three-point Slight reflux of the valve. Considering that it is a clinical diagnosis case of complication flukesomyces disease, the child was given a praziquantel tablet,25 mg/kg,3 times a day, for 3 consecutive days. The treatment was treated at the above dose for 1 week interval for 1 course of treatment, and 3 courses were given. After three months, the child recovered well after the follow-up visit. The child did not complain of special discomfort, and the CT showed a small amount of effusion.

Objective: To improve the efficiency of patient treatment in routine, emergency, and mass casualty scenarios (both peacetime and wartime), eliminate reliance on blood type compatibility, and promote the productization of platelet-rich plasma (PRP), this study investigated the optimal mixing ratio for developing a universal PRP formulation. Methods: PRP was prepared from donors with blood types O, A, B, and AB. Samples were mixed in varying proportions, and the optimal ratio was determined based on the trend of anti-A and anti-B antibody titers in the mixed PRP. Concentrations of the growth factors PDGF-AA, PDGF-BB, EGF, TGF-β1, and VEGF were measured by enzyme-linked immunosorbent assay (ELISA) before and after mixing. Results: A mixing ratio of A∶B∶AB=6∶2.5∶24 resulted in no detectable agglutination with either A or B cells in the microcolumn gel system, indicating the absence of immunological reactivity and confirming universal compatibility. Importantly, the levels of all measured growth factors remained unchanged following mixing, suggesting preservation of biological activity. Conclusion: These findings suggest that universal PRP can be prepared by neutralizing blood type antibodies through antigen-antibody reactions.

Objective: To investigate the associations of screen time (ST) and dietary behavior with sleep quality among first-year junior high school students, and further analyze the joint exposure effect of weekend ST and dietary usage, so as to provide scientific evidence for improving adolescent sleep quality and developing related health intervention measures. Methods: From September 19 to October 18, 2023, a combination of cluster sampling and convenience sampling method was used to select 733 first-year junior high school students from 4 public junior high schools in Jinshan District, Shanghai. ST on weekdays and weekends of students was investigated. The Chinese Diet Quality Questionnaire and the Pittsburgh Sleep Quality Index were applied to assess dietary behaviors and sleep quality. Binary Logistic regression was used to analyze the associations of ST and dietary behavior with sleep quality during weekdays and weekends. Results: The proportion of students with high level ST was 31.8% on weekdays and 65.3% on weekends. Students with poor dietary quality accounted for 45.3%, and the detection rate of poor sleep quality was 14.6 %. Binary Logistic regression analysis showed that, compared with students with low level ST on weekend and good dietary quality, those with high level ST on weekend and those with poor dietary quality had increased risks of poor sleep quality [ OR (95% CI )=1.89(1.10-3.26), 2.30(1.47-3.58), both P <0.05]. Combined exposure showed that compared to students with good diet quality and low level ST on weekend, students with good dietary quality and high level ST on weekend, those with poor dietary quality and low level ST on weekend, and those with poor dietary quality and high level ST on weekend also had increased risks of poor sleep quality [ OR (95% CI )=3.00(1.25-7.25), 4.07(1.60-10.33), 5.72(2.37-13.81), all P <0.05]. Conclusion Excessive weekend ST and poor dietary quality are associated with poor sleep quality among first-year junior high school students, and their co-occurrence further increases the risk.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by persistent inflammation and joint damage, accompanied by the accumulation of plasma cells, which contributes to its pathogenesis. Understanding the genetic alterations occurring during plasma cell differentiation in RA can deepen our comprehension of its pathogenesis and guide the development of targeted therapeutic interventions. Here, our study elucidates the intricate molecular mechanisms underlying plasma cell differentiation by demonstrating that PRDX1 interacts with DOK3 and modulates its degradation by the autophagy-lysosome pathway. This interaction results in the inhibition of plasma cell differentiation, thereby alleviating the progression of collagen-induced arthritis. Additionally, our investigation identifies Salvianolic acid B (SAB) as a potent small molecular glue-like compound that enhances the interaction between PRDX1 and DOK3, consequently impeding the progression of collagen-induced arthritis by inhibiting plasma cell differentiation. Collectively, these findings underscore the therapeutic potential of developing chemical stabilizers for the PRDX1-DOK3 complex in suppressing plasma cell differentiation for RA treatment and establish a theoretical basis for targeting PRDX1-protein interactions as specific therapeutic targets in various diseases.

OBJECTIVE To evaluate the efficacy and safety of intranasal corticosteroids （INCS） combined with oral H1- antihistamine （AH） in the treatment of allergic rhinitis. METHODS A comprehensive literature search was conducted in PubMed， Embase， CNKI， and VIP database to collect randomized controlled trial （RCT） that INCS combined with AH （experimental group） versus INCS （control group） in the treatment of allergic rhinitis from the inception to December 31， 2024. After study selection， data extraction， and quality assessment， a meta-analysis was performed by using RevMan 5.3 software. RESULTS A total of 12 RCTs were included in the meta-analysis， with a total of 1 842 patients. Results of meta-analysis showed that， compared with the control group， patients in the experimental group had a greater reduction in sneezing scores， rhinorrhea scores， nasal congestion scores， nasal itching scores， total nasal symptom scores， total ocular symptom scores， and rhinoconjunctivitis quality of life questionnaire scores （P＜0.05）. The incidence of headache was lower in the experimental group （P＜0.05）； whereas there were no significant differences between the two groups in the incidence of nosebleed， dryness of the mouth and nose， drowsiness， fatigue， and total adverse events （P＞0.05）. CONCLUSIONS Compared with INCS monotherapy， the combination of INCS and oral AH provides superior efficacy and safety in the treatment of allergic rhinitis.

Objective: To investigate the distribution characteristics and related factors of weight loss behavior among middle school students in Shanghai, so as to provide a reference for guiding scientific weight loss among middle school students. Methods: From May to June 2021, a stratified cluster random sampling method was used to select 16 758 junior and high school students in 16 districts of Shanghai. Youth Risk Behavior Surveillance System was administered to assess the basic condition and weight loss behaviors of the students. An unordered multinomial Logistic regression model was employed to analyze the factors associated with weight loss behaviors. Results: A total of 5 881 (35.09%) reported engaging in exercise for weight loss, 6 344 (37.86%) reported dieting for weight loss, and 461 (2.75%) engaged in unhealthy weight loss behaviors. The unordered multinomial Logistic regression analysis indicated that compared with the no weight loss behavior group, students from urban areas( OR =1.35,95% CI =1.10-1.66), those with Internet addiction ( OR =1.71,95% CI =1.23-2.38), those with victims of bullying ( OR =2.09, 95% CI =1.68-2.61), those experiencing insomnia ( OR =2.33,95% CI = 1.74-3.11), those feelings of sadness or despair ( OR =3.10, 95% CI =2.42- 3.97 ), and those who perceived their body weight as slightly heavy ( OR =2.77, 95% CI = 2.17-3.55) or very heavy ( OR =3.41, 95% CI =2.44-4.75) were more likely to engage in unhealthy weight loss behaviors ( P <0.05). Conclusions There are significant differences in weight loss behaviors among middle school students with varying characteristics in Shanghai. Negative emotions such as insomnia and feelings of sadness or despair, Internet addiction, cognitive bias in weight and experiences of bullying are identified as related factors for unhealthy weight loss behaviors. Targeted intervention measures should be implemented to guide students towards scientific approaches to weight management.

Objective: To investigate the association of moderate to vigorous intensity physical activity (MVPA) and screen time (ST) with emotional and behavioral problems in middle school students, so as to provide a basis for improving the mental health level of adolescents. Methods: Four public junior high schools in Jinshan District, Shanghai were selected by random cluster method from September 19 to October 18, 2023, with 779 first grade students included. Strengths and Difficulties Questionnaire (SDQ), as well as physical activity and screen time were collected. Binary Logistic regression analysis was used to investigate the association between MVPA, ST and different dimensions of emotional and behavioral problems. Results: Students with MVPA<60 min/d accounted for 82.4%, and with ST>2 h/d accounted for 29.5%. The abnormal rate of SDQ dimensions among students ranged from 6.8 % to 19.3%, with the highest abnormal rate observed in behavioral problems. The results of binary Logistic regression analysis showed that, compared with high level of MVPA, students with low level of MVPA had a significantly increased risk of developing problems in prosocial behavior [ OR (95% CI )=2.16(1.37-3.41), P <0.05]. Compared with low level ST, students with high level had an increased risk of experiencing emotional symptoms, behavioral problems and peer interaction problems [ OR (95% CI )=2.00(1.25-3.22), 2.00(1.41-2.84), and 1.69(1.22-2.33), P <0.05]. Compared with high MVPA and low ST, students with low MVPA and high ST had an increased risk of developing problems in the dimensions of conduct problems, prosocial behavior, and overall difficulty score [ OR (95% CI )=1.92(1.13-3.23), 2.73(1.56-4.77), and 2.07(1.19-3.60), P <0.05]. Conclusions Physical activity and screen time are related to emotional and behavioral problems in middle school students. Insufficient physical activity time and excessive screen time might increase the risk of emotional and behavioral problems. Interventions can be administered on physical activity and screen time among adolescents to promote their mental health.

Objective To investigate the correlation of peripheral blood follicle suppressor-like protein L(FSTL-1)and chitosanidase 1(CHIT-1)levels with cardiovascular diseases(CVD)in hemodialysis patients and their clinical value.Methods A total of 150 hemodialysis patients treated in Chongqing Liangjiang New Area People's Hospital from January 2021 to June 2023(case group)and 60 healthy people who underwent medical checkups(control group)were selected.The case group consisted of 62 patients who had CVD(CVD group)and 88 patients who did not have CVD(non-CVD group).Enzyme-linked immunosorbent assay was used to detect the levels of FSTL-1 and CHIT-1 in peripheral blood.The levels of FSTL-1 and CHIT-1 among the groups were compared,and the correlation between the levels of FSTL-1 and CHIT-1 with the Gensini scores,high-sensitivity C-reactive protein(hs-CRP),troponin T(cTnT),and left ventricular ejection fraction(LVEF)were analyzed by Pearson's correlation test.Multivariate Logistic regression was used to analyze the influencing factors affecting the occurrence of CVD.Receiver operating characteristic(ROC)curve was used to assess the predictive efficacy of FSTL-1 and CHIT-1 for the occurrence of CVD.Results The levels of FSTL-1 and CHIT-1 were higher in the CVD group and non-CVD group than those in the control group(F=229.200,273.200,P＜0.05),and the levels of FSTL-1 and CHIT-1 in the CVD group were higher than those in the non-CVD group(P＜0.05).The peripheral blood FSTL-1 and CHIT-1 levels in hemodialysis patients were positively correlated with Gensini score,cTnT,hs-CRP(r=0.662,0.724,0.712,r=0.679,0.502,0.341,P＜0.05)and negatively correlated with LVEF(r=-0.463,-0.581,P＜0.05).Compared with the non-CVD group,CVD group had longer chronic kidney disease duration,higher hs-CRP,cTnT,Gensini score,FSTL-1,CHIT-1(P＜0.05),and lower LVEF(P＜0.05).High levels of cTnT,FSTL-1,and CHIT-1 were independent risk factors for CVD in hemodialysis patients(P＜0.05).The area under the curve of the com-bined detection of peripheral blood FSTL-1 and CHIT-1 levels for predicting the occurrence of CVD in hemo-dialysis patients was 0.852(95％CI:0.789-0.915),which was significantly larger than those of the single index of FSTL-1 and CHIT-1(Z=-2.084,-3.112,P=0.038,0.002).Conclusion The increased levels of peripheral blood FSTL-1 and CHIT-1 levels in CVD patients are correlated with cardiovascular injury,cardiac function,and inflammatory indexes in hemodialysis patients,which are independent risk factors affecting the occurrence of CVD in hemodialysis patients,and the combined detection of the two could improve the predic-tive efficacy for the occurrence of CVD in hemodialysis patients.
