ObjectiveTo establish a high-performance liquid chromatography（HPLC） for the quantitative analysis of multiple components in Gegen Qinlian tablets， and to comprehensively evaluate the quality of samples from different manufacturers by integrating chemical pattern recognition and technique for order preference by similarity to ideal solution（TOPSIS）， in order to provide a reference basis for quality evaluation and control of Gegen Qinlian tablets. MethodsHPLC was employed to determine the contents of 10 components in 28 batches of Gegen Qinlian tablets collected from 6 manufacturers， and taking the detection results as variables， SIMCA 14.1 and SPSS 26.0 were employed for cluster analysis（CA）， principal component analysis（PCA）， and orthogonal partial least squares-discriminant analysis（OPLS-DA） to identify key components affecting the quality. Then， TOPSIS analysis was employed to rank the quality of Gegen Qinlian tablets from the 6 manufacturers and establish a comprehensive quality evaluation method. ResultsA quantitative method for Gegen Qinlian tablets was established. After methodological validation， the method was found to be stable and reliable， and could be used for the quantitative analysis of this preparation. The contents of 3′-hydroxy puerarin， puerarin， 3′-methoxy puerarin， daidzein， coptisine hydrochloride， epiberberine， jatrorrhizine hydrochloride， berberine hydrochloride， palmatine hydrochloride and baicalin in 28 batches of samples were 3.58-7.35， 24.88-42.32， 4.20-9.36， 4.33-7.60， 2.52-6.44， 0.93-4.10， 0.58-3.05， 10.68-22.92， 0.82-4.82， 11.73-60.16 mg·g^-1， respectively. Among them， puerarin， berberine hydrochloride and baicalin all met the limit requirements for this preparation specified in the 2025 edition of the Pharmacopoeia of the People's Republic of China. CA and PCA clustered the 28 batches of samples into 5 categories， PCA extracted 2 principal components with a cumulative variance contribution rate of 90.588%， and OPLS-DA screened out 4 differential markers with variable importance in the projection（VIP） values>1.0， namely baicalin， 3′-hydroxy puerarin， coptisine hydrochloride and palmatine hydrochloride， which might be the main components affecting the quality of Gegen Qinlian tablets. TOPSIS analysis showed that the comprehensive score of each evaluation index（C_i） values of different manufacturers were different. Among them， the C_i of manufacturer B was ranked higher， indicating potentially superior quality， while the C_i of manufacturer A was ranked lower， suggesting potentially inferior quality. ConclusionThis study establishes a quantitative method for Gegen Qinlian tablets， and the content uniformity of the same manufacturer is good， while there are differences in the contents of active components among different manufacturers. Through the chemical pattern recognition analysis， it is found that the content differences of Gegen Qinlian tablets may be related to baicalin， 3′-hydroxy puerarin， coptisine hydrochloride and palmatine hydrochloride.

Objective To analyze the overall characteristics, research hotspots, and development trends of immune cell-related studies in radiotherapy for rectal cancer. Methods A systematic search was conducted by using Web of Science Core Collection to retrieve articles related to radiation therapy and immune cells in rectal cancer published from 1991 to 2024. Advanced bibliometric tools, such as VOSviewer and CiteSpace, were utilized to facilitate analysis and describe publication trends, geographic contributions, institutional affiliations, journal prominence, author collaboration, and prominent keywords. Results The annual number of relevant publications has increased steadily, showing remarkable growth over the past five years. Studies focusing on adaptive immune cells (T and B cells) account for the largest proportion of works and form the most extensive collaboration networks, reflecting the central role of T cell–mediated antitumor immunity in radiotherapy. Meanwhile, innate immune cells, including myeloid-derived suppressor cells, macrophages, monocytes, and neutrophils, are increasingly investigated for their regulatory roles in shaping the tumor immune microenvironment and influencing therapeutic responses. Among countries, China and the United States have contributed the highest number of publications and demonstrated strong academic influence. While several stable research groups have been formed, intergroup collaboration remains limited. Keyword analysis revealed that radiotherapy-induced immune modulation, tumor immune microenvironment remodeling, and treatment response have emerged as major research hotspots. Conclusion Research on immune cells in rectal cancer radiotherapy has progressed rapidly in recent years. The emphasis of this field has gradually shifted from single-treatment approaches to mechanistic studies investigating the interaction between radiotherapy and the tumor immune microenvironment. The field still demonstrates considerable potential for future research and clinical translational applications.

Objective To investigate the association between dietary patterns and adolescent development in girls in Pudong New Area，Shanghai. Methods Using a stratified cluster sampling method, a total of 998 girls were selected from the cohort of growth, development, and health of children and adolescents in Pudong New Area of Shanghai. Physical development examinations and dietary surveys were conducted on these girls. Principal component analysis was used to determine girls' dietary patterns, and their relationship with adolescent development was analyzed using logistic regression. Results Among the 998 participants, 770 (77.15%) were pubertal girls. The factor analysis identified three dietary patterns, fungi and algae~nuts~legumes pattern, meat-vegetables and fruits-cereals pattern, and milk-eggs pattern. Logistic regression analysis revealed that after adjusting for age, waist circumference, residential district, mother's education level, and father's education level, the Q2 level (OR=0.54, 95% CI: 0.30-0.99), Q3 level (OR=0.50, 95% CI: 0.27-0.91), and Q4 level (OR=0.49, 95% CI: 0.26-0.90) of the fungi and algae-nuts-legumes pattern were negatively correlated with adolescent development. The Q2 level (OR=0.48, 95% CI: 0.27-0.87) and Q3 level (OR=0.49, 95% CI: 0.27-0.88) of the milk-eggs pattern were also negatively correlated with adolescent development. Conclusion The fungi and algae~nuts~legumes pattern and milk-eggs patterns are inversely related to pubertal development.

Objective:To investigate the effect of bed board of carbon fiber for treatment combined with fixed bottom board on verification results of Portal Dosimetry(PD)dose of intensity-modulated radiation therapy(IMRT)plan of fixed field for cervical cancer.Methods:A total of 15 patients with cervical cancer who admitted to Nanjing First Hospital from January 2019 to January 2020 were retrospectively selected,and the IMRT plans of fixed field for all patients were designed.The radiation field with 180° gantry angle was selected for each case to make the corresponding PD dose verification plan,and each verification plan included two subfields:AA180_0 and AA180_1.Three types of materials were placed between the accelerator head and the electronic portal imaging device(EPID),which included material without carbon fiber,bed board with carbon fiber for treatment,and the combination of the bed board with carbon fiber for treatment and the fixed bottom board with carbon fiber,when the Clinac iX accelerator was used to conduct verification plan for each case.The γ passing rates of the subfields(AA180_0 and AA180_1)and the total field(AA180)among three kinds of conditions,which included material without carbon fiber,bed board with carbon fiber for treatment,and the combination of the bed board with carbon fiber for treatment and the fixed bottom board with carbon fiber,were compared and analyzed.Results:For the subfield AA180_0,the γ passing rates under three different material conditions were respectively(96.09±1.38)%,(90.48±2.24)%and(81.85±2.46)%.For the subfield AA180_1,the γ passing rates under the above conditions were respectively(96.05±1.06)%,(91.86±2.22)%and(86.26±2.74)%.For the total field AA180,the γ passing rates were respectively(90.78±1.40)%,(84.82±2.56)%and(78.49±3.18)%.The γ passing rates of the subfield AA180_0,subfield AA180_1,and the total field AA180 showed statistically significant differences among the three different material conditions(F=177.80,80.00,91.42,P<0.01).Compared with materials without carbon fiber,the γ passing rate of the total field AA180 of the combination of the bed board with carbon fiber for treatment and the fixed bottom board with carbon fiber significantly decreased by 12.29%.Conclusion:In the PD dose verification of IMRT for cervical cancer,the bed board with carbon fiber for treatment combined with the fixed bottom board will produce adverse effect for the verification results.The effect of the single use of bed board for treatment is relatively small.The combined use of the bed board with carbon fiber for treatment and the fixed bottom board will lead to a significant deterioration in the verification result of PD dose.

Objective:To develop the Body Image Flexibility Questionnaire for Middle School Students(BIFQ-MS)and test its validity and reliability.Methods:Firstly,the initial questionnaire was developed based on the hexaflex model of psychological flexibility.Secondly,701 middle school students were selected to complete the initial questionnaire for item analysis and exploratory factor analysis.Thirdly,899 middle school students were ex-amined to conduct confirmatory factor analysis,criterion-related validity and internal consistency tests on the formal questionnaire.The Body Image-Acceptance and Action Questionnaire(BI-AAQ),Avoidance and Fusion Question-naire for Youth(AFQ-Y8),Body Areas Satisfaction Scale(BASS),and General Appearance subscale of the Nega-tive Physical Self Scale(NPSS-GA)were used to test criterion validity.In addition,88 middle school students were retested 4 weeks later.Results:The BIFQ-MS consisted of 26 items,including 4 factors(openness to experience,self-as-context,contact with the present moment,and valued action),which explained 65.55％of the total vari-ance.Confirmatory factor analysis showed that the four-factor structural model fitted well(x2/df=2.26,CFI=0.97,TLI=0.97,RMSEA=0.04,SRMR=0.03).The BIFQ-MS total scores and the scores of each factor were positively correlated with the scores of the BI-AAQ and the BASS(r=0.41-0.50,Ps＜0.01),whereas they were negatively correlated with the scores of the NPSS-GA and the AFQ-Y8(r=-0.28--0.58,Ps＜0.01).The Cronbach's α coefficients of the total questionnaire and the 4 factors ranged from 0.91 to 0.97,and the test-retest reliabilities(ICC)ranged from 0.70 to 0.86.Conclusion:The Body Image Flexibility Questionnaire for Middle School Students is a reliable tool for understanding body image flexibility in adolescents.

Objective This study aimed to evaluate the clinical effect of hyaluronic acid(HA)scaffold combined with adipose-derived stem cells(ADSCs)in chronic wound healing of lower limbs and explore its applica-tion potential in promoting chronic wound healing.Methods A total of 50 patients were included in this study.They were divided into study and control groups according to the random number table method.There were 25 cases in each of the two groups of patients.HA and ADSCs were mixed in a 1:1 ratio and evenly injected into the wound base and the subcutaneous tissue around the wound at a rate of 0.1 ml/cm3.In the control group,ADSCs were only injected into the wound base and subcutaneous tissue around the wound.The infection rate,treatment satisfaction,wound healing rate,visual analogue score(VAS),and wound quantitative score were compared between the two groups at 7 days,14 days,and 28 days.Results The infection rate in the study group was lower than that in the control group,and the difference was statistically significant(P<0.05).Moreover,at 14 days and 28 days after treatment,the wound healing rate in the study group was higher than that in the control group,and the difference was statistically significant(P<0.05).On the 7th,14th,and 28th days after treatment,the VAS scores and the wound quantitative scores were lower than those in the control group,and the difference was statisti-cally significant(P<0.05).Furthermore,the treatment satisfaction rate in the research group(92％)was higher than that in the control group(80％).Conclusion HA scaffold combined with ADSCs could promote the healing of chronic wounds in lower limbs,reduce infection rate,and relieve wound pain,which provides a new idea for the treatment of chronic wounds.

Objective:To explore the spatial correlation between gray matter volume (GMV) changes and neurotransmitter receptors/transporters in patients with first-episode schizophrenia (FES) .Methods:Fifty-four FES patients(FES group) and fifty-nine healthy controls (HC group) were selected from June 2014 to May 2020 in the Psychiatry Department of Renmin Hospital of Wuhan University. Structural magnetic resonance imaging (sMRI) was conducted on all subjects. Differences of GMV were compared across 400 cortical regions and 32 subcortical regions. Based on the positron emission tomography(PET) data from Neuromaps, which provides the density of 19 different neurotransmitter receptors and transporters, Spearman correlation analysis was performed to evaluate the spatial correlation between GMV changes and neurotransmitter systems.Results:Compared to the HC group, FES group exhibited significant GMV reductions in widespread cortical (90/400) and subcortical (6/32) regions (all FDR-corrected P<0.05). The effect size of GMV reduction (Cohen’s d) showed significant positive correlations with the density of 5-hydroxytryptamine 1a(5HT1a) ( r=0.400, Pspin=0.002), γ-aminobutyric acid type A receptor(GABA A)( r=0.307, Pspin=0.002), and metabotropic glutamate receptor 5(mGluR5) ( r=0.275, Pspin=0.020) receptors (all FDR-corrected P<0.05). Conclusion:GMV reductions in a wide range of brain regions existed in patients with FES. There are significant correlations between 5HT1a, GABA A and mGluR5 receptors and gray matter reduction in patients with FES. The disorder of these neurotransmitter receptors may be the potential neurobiological mechanism of gray matter structural abnormalities in the early stage of schizophrenia.
