Objective This study applies Roy adaptation theory to deeply explore the experience of food avoid-ance behavior in patients with inflammatory bowel disease(IBD),offering insights for developing dietary management strategies.Methods A descriptive qualitative research method was employed.By purposive sampling,24 IBD pa-tients hospitalized in the gastroenterology department of a tertiary hospital in Nanjing from July 2022 to December 2024 were selected for semi-structured interviews.Data were analyzed using a directed content analysis approach.Results This study identified 4 main themes and 11 sub-themes,encompassing overattribution leading to inappro-priate avoidance(recurrent symptoms triggering overattribution,disease staging triggering inappropriate avoidance),negative self-perception leading management struggles(illness fear diminishing self-efficacy,disease trauma eroding self-identity,knowledge deficiency constraining self-determination),functional impairment intensifying role challenges(role internalization undermining social function,social roles relinquishing dietary management),and external con-straints amplifying practical difficulties(family and friend oversight heightening dietary stress,healthcare gaps foster-ing practical helplessness,traditional beliefs restricting dietary exploration,economic hardship limiting balanced nu-trition).Conclusion The interplay of overattribution,negative self-perception,functional impairment,and external constraints in IBD patients hinders their ability to adapt to disease fluctuations,ensnaring them in the adaptive predicament of food avoidance behavior.Healthcare professionals should comprehensively address these factors by fostering accurate perceptions,enhancing psychological support,guiding effective coping strategies,and optimizing ex-ternal resources,thereby improving patients' overall adaptive capacity and promoting their recovery.

Objective To establish a method for the simultaneous determination of peimine,peiminine,and hupehenine in Juhong pills,to investigate the raw material usage of Fritillaria thunbergii Miq.,and to preliminarily develop a detection approach for identifying adulteration with Fritillaria hupehensis Hsiao et K.C.Hsia.Methods The high-performance liquid chromatography-triple quadruple mass spectrometry(HPLC-MS/MS)was performed on an Agilent Poroshell 120 SB C18 column(2.1 mm×100 mm,2.7 μm)with a mobile phase consisting of acetonitrile-methanol(1∶1)and 0.1%formic acid under gradient elution.The flow rate was set at 0.3 mL·min-1.The column temperature was maintained at 35℃,and the injection volume was 2 μL.Electrospray ionization(ESI)in positive ion mode and multiple reaction monitoring were employed to quantify the three components in 170 batches of Juhong pills.Simulated positive samples with varying adulteration ratios of Fritillaria hupehensis Hsiao et K.C.Hsia were prepared to establish a simple yet efficient detection limit for adulteration.Results Three components showed good linear correlation within their ranges(r≥0.997 5),and the averaged recoveries ranged from 92.0%-106.2%.A total of 61 batches were suspected of Fritillaria thunbergii Miq.adulteration with Fritillaria hupehensis Hsiao et K.C.Hsia in raw material inputs,with the peimine to peiminine ratio below 1.15.Among these samples,27 batches were large honey-bound pills with hupehenine levels of 2.636-9.939 μg·g-1;34 batches were water-honeyed pills showing significantly higher hupehenine contamination at 6.752-48.137 μg·g-1.Conclusion The established method is simple,reliable,and accurate for the quality control of Fritillaria thunbergii Miq.adulteration in Juhong pills without imposing significant additional costs.

Objective:To translate the Vascular Quality of Life Questionnaire-6 (VQ6) into a Chinese version and to test its reliability and validity in patients with peripheral arterial disease.Methods:The English version of VQ6 scale was sinicized following the Brislin translation guidelines, and the Delphi consultation was used for cultural debugging to form the Chinese version of the VQ6. Convenience sampling was used to select 146 patients with peripheral arterial disease who attended the Department of Interventional and Vascular Surgery and the Department of Endocrinology of Affiliated Hospital of Nantong University from May to June 2024 for the survey. Data were analyzed using SPSS 26.0 and Amos 26.0. Correlation analysis and critical ratio method were used for item analysis and content validity index was used to evaluate content validity. The Chinese version of the Patient-Reported Outcomes Measurement Information System 29 Profile V2.1 (PROMIS-29 Profile v2.1) was selected as a validity scale to evaluate the criterion-related validity. Exploratory factor analysis and confirmatory factor analysis were used to evaluate the structural validity of the scale, and transgender test was used for measurement equivalence. Reliability of the scale was evaluated with the Cronbach's α coefficient and retest reliability index.Results:The Chinese version of the VQ6 scale had six items. The scale-level content validity index was 0.972, and the item-level content validity index ranged from 0.833 to 1.000. One common factor was extracted with a cumulative variance contribution of 83.526%. Criterion-related validity showed that the correlation coefficient between the Chinese version of the VQ6 and the PROMIS-29 Profile v2.1 was 0.688 ( P<0.01) . The scale essentially satisfied Δ RMSEA < 0.015 and Δ CFI < 0.01 in the transgender equivalence test. The Cronbach's α coefficient for the scale was 0.968 and the retest reliability was 0.978. Conclusions:The Chinese version of the VQ6 has good reliability and validity and is suitable as an assessment tool for quality of life in patients with peripheral arterial disease in our cultural context.

Objectives:To report the sexual functional outcomes of vaginal dilation therapy in Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome patients.Methods:From March 2020 to February 2023, 97 MRKH syndrome patients performed vaginal dilation therapy with guidance from Peking Union Medical College Hospital, and 45 of them engaged in penetrative intercourse and were included in this prospective cohort study. The Chinese version of female sexual function index (FSFI) was used to assess sexual function. Functional success was defined as FSFI>23.45. Forty age-matched healthy women were selected as controls. Kaplan-Meier survival analysis was used to calculate the median time to success. Pearson correlation analysis was used to explore the relationship between neovagina length and sexual function. Complications were collected using follow-up questionnaires.Results:The functional success rate of vaginal dilation therapy was 89% (40/45) with a median time to success of 4.3 months (95% CI: 3.0-6.1 months). Compared to controls, MRKH syndrome patients had significantly lower scores in the orgasm domain (4.72±1.01 vs 4.09±1.20; P=0.013) and pain domain (5.03±0.96 vs 4.26±0.83; P<0.001). However, there were no significant differences in the FSFI total score (26.77±2.70 vs 26.70±2.33; P=0.912), arousal domain (4.43±0.77 vs 4.56±0.63; P=0.422) and satisfaction domain (4.88±0.98 vs 4.65±0.86; P=0.269) between MRKH syndrome patients and controls. MRKH syndrome patients had significantly higher scores in the desire domain (3.33±0.85 vs 3.95±0.73; P<0.001) and lubrication domain (4.37±0.56 vs 5.20±0.67; P<0.001). The prevalence of sexual dysfunction in MRKH patients was non-inferior to controls: low desire [3% (1/40) vs 23% (9/40); P=0.007], arousal disorder [3% (1/40) vs 3% (1/40); P>0.999], lubrication disorder [5% (2/40) vs 25% (10/40); P=0.012], orgasm disorder [40% (16/40) vs 20% (8/40); P=0.051], sexual pain [30% (12/40) vs 15% (6/40); P=0.108]. Conclusions:MRKH syndrome patients undergoing non-invasive vaginal dilation therapy could achieve satisfactory sexual life. Given its high functional success rate and slight complication, vaginal dilation therapy should be recommended as the first-line option, reducing the need for unnecessary surgeries.

In the backdrop of the new era,enhancing Party building in public hospitals,particularly the united front work,holds great significance for elevating medical service standards,fostering harmonious doctor-patient relationships,consoli-dating mechanisms of unity,and promoting the high-quality development of hospitals.In this case study with the First Affiliated Hospital of Soochow University,the authors explored how public hospitals can effectively conduct united front work in the context of strengthening Party construction and leveraging this work to promote comprehensive development in all aspects of the hospital.

Recent progress in targeted metabolic therapy of cancer has been limited by the considerable toxicity associated with such drugs. To address this challenge, we developed a smart theranostic prodrug system that combines a fluorophore and an anticancer drug, specifically 6-diazo-5-oxo-l-norleucine (DON), using a thioketal linkage (TK). This system enables imaging, chemotherapy, photodynamic therapy, and on-demand drug release upon radiation exposure. The optimized prodrug, DON-TK-BM3, incorporating cyanine dyes as the fluorophore, displayed potent reactive oxygen species release and efficient tumor cell killing. Unlike the parent drug DON, DON-TK-BM3 exhibited no toxicity toward normal cells. Moreover, DON-TK-BM3 demonstrated high tumor accumulation and reduced side effects, including gastrointestinal toxicity, in mice. This study provides a practical strategy for designing prodrugs of metabolic inhibitors with significant toxicity stemming from their lack of tissue selectivity.

OBJECTIVE To investigate the effect of polymorphisms of solute carrier organic anion transporter family, member 1B3(SLCO1B3) gene on the pharmacodynamics of mycophenolate mofetil(MMF) in patients with lupus nephritis. METHODS Patients with lupus nephritis who were treated in Jieyang People’s Hospital from September 2019 to April 2021 were selected. All subjects were treated with MMF for at least 12 months, or discontinued due to poor efficacy. The efficacy of MMF was evaluated. The SLCO1B3 334T>G/699G>A(rs4149117/rs7311358) genotype was detected using Agena MassARRAY®, and the correlation between gene polymorphisms and MMF pharmacodynamics was analyzed using SPSS 25.0 software. RESULTS The genotype frequencies of SLCO1B3 334T>G/699G>A were in Hardy-Weinberg equilibrium. The probability of poor MMF treatment effect of 334GG/699AA carriers was significantly higher than that of 334TT/699AA and 334TG/699GA carriers(P<0.001); Logistic regression showed that both 334GG/699AA and urine protein>2.5 g·(24 h)−1 were the risk factors for poor MMF treatment[OR=4.038(1.731, 9.420), P<0.001; OR=4.157(1.705, 10.137), P=0.002]. Combined analysis showed that patients with both 334GG/699AA genotype and urine protein>2.5 g·(24 h)−1 were at higher risk for poor efficacy[OR=8.563(3.301, 22.216), P<0.001]. CONCLUSION SLCO1B3 334T>G/699G>A is related to the efficacy of MMF treating lupus nephritis, and 334GG/699AA carriers are more likely to result in poor efficacy.
