Objective To explore current status and potential subtypes of elderly stroke patients' medication literacy among,and to analyze related influencing factors of different subtypes.Methods A total of 285 elderly stroke patients admitted in the First Affiliated Hospital of Zhengzhou University from November 2023 to June 2024 were selected as subjects.General Information questionnaire,medication literacy scale for elderly patients with chronic diseases,and perceived social support scale were conducted.Latent profile analysis(LPA)of elderly stroke patients' medication literacy was conducted,and Logistic regression analysis was used to explore influencing factors of different profiles.Results Score of medication literacy scale for elderly stroke patients was(48.26±12.51)points.Medication literacy among elderly stroke patients can be divided into 3 profiles,namely proactive-high literacy type(51.9％),balanced-medium literacy type(34.0％),and dependent-low literacy type(14.1％).Logistic regression analysis showed that recent medication types,current place of residence,educational level,diabetes,and social support were the influencing factors of elderly stroke patients' medication literacy(P＜0.05).Conclusion The level of medication literacy among elderly stroke patients is medium,which is characterized by 3 categories.Medical staffs targeted intervention should be adopted according to different category characteristics,so as to accurately meet their nursing needs,finally improve the level of elderly stroke patients' medication literacy.

Background: Condyloma acuminatum (CA) is a common sexually transmitted disease caused by human papillomavirus (HPV). In recent years, research on anal CA has primarily focused on treatment rather than underlying mechanisms. The mechanism of HPV persistence and recurrence in CA require further exploration. It needs multiple researches in mechanisms to focalize treatment targets. Objective: To investigate the relationship between intestinal mucosal immunity and the relapse of anal CA and persistent infection. Methods: Levels of interferon gamma (IFN-γ) and secretory immunoglobulin A (sIgA) were measured using enzyme-linked immunosorbnent assay in anal mucosal cells obtained from patients treated at Tianjin Union Medical Center from September 2022 to December 2024. All the participants signed Informed Consent and the whole plan was approved by Institutional Review Board in Tianjin Union Medical Center (No. B155). Results: The levels of IFN-γ and sIgA significantly decreased after infection, and persistent infection exhibited even lower levels. These two factors increased following treatment, reaching peak concentrations at 4 weeks before decreasing again. Conclusion These findings demonstrate a significant association between persistent anal CA infection and dysregulation of intestinal mucosal immunity.

【Objective】 To evaluate the efficacy and safety of intravaginal fractional superpulse CO2 laser in the treatment of mild to moderate female stress urinary incontinence (SUI), so as to provide reference for the treatment options for female SUI. 【Methods】 A total of 41 female mild-to-moderate SUI patients confirmed at the Department of Urology, The First Affiliated Hospital, Air Force Medical University, during Aug.2019 and Nov.2020 were involved.All patients received 3 intravaginal fractional superpulse CO2 laser treatments (1/month).The improvement of urinary incontinence symptoms after treatment was evaluated with International Consultation on Incontinent Questionnaire Short Form (ICI-Q-SF).The motion of bladder neck and rotation angle of bladder and urethra were measured with pelvic ultrasound before and after treatment.The therapeutic effects, pain and patients’ satisfaction were evaluated, and adverse reactions such as bleeding, infection and scar were observed. 【Results】 Three months after treatment, urinary incontinence symptoms improved to varying degrees, the ICI-Q-SF score decreased, the motion of bladder neck [ (28.70±3.11) mm vs.(19.10±4.54) mm] and the vesicourethral rotation angle [(52.78°±15.79°) vs.(41.56°±13.24°)] significantly decreased (P<0.05).The total effective rate was 100.0%.No patients complained severe pain during treatment.All patients were satisfied with the treatment.No adverse reactions such as bleeding, infection or scar occurred. 【Conclusion】 Intravaginal fractional superpulse CO2 laser is effective and safe in the treatment of mild to moderate female SUI, but the long-term efficacy still needs further observation.

Objective:To observe the changes of pelvic floor structure and function in female vaginal laxity after CO 2 fractional laser transvaginal treatment. Methods:This study reviewed the improvement of pelvic floor structure and function after CO 2 fractional laser transvaginal treatment in 28 female patients [aged 26-59 (37.5±8.3) years] with vaginal laxity syndrome seen at the Department of Dermatology, the First Affiliated Hospital of Air Force Medical University from March 2020 to November 2021. A total of 28 female patients with vaginal laxity syndrome underwent intravaginal treatment by CO 2 fractional laser instrument once/month for 3 times. The clinical efficacy and safety were evaluated according to the pre- and post-treatment transverse vaginal diameter, FSFI score of female sexual function, VHIS score of vaginal environment, vaginal tactile imaging system (VTI), pelvic ultrasound and MRI, tissue biopsy, patient satisfaction, pain score, and postoperative adverse effects. Results:Twenty-one of the twenty-eight female patients with vaginal laxity syndrome showed significant improvement in symptoms related to vaginal laxity syndrome after intravaginal treatment with CO 2 fractional laser therapy. All patients showed improvement in all indexes before and 1 month after treatments the mean vaginal transverse diameter decreased from (3.00±0.39) fingers to (2.71±0.40) fingers ( P<0.05), VHIS increased from (17.12±3.97) to (21.69±3.61) ( P<0.05), FSFI score improved from (23.11±3.70) to (27.43±5.33) ( P<0.05), and VTI examination showed that vaginal muscle strength and elasticity were improved to different degrees, and there was a statistical difference compared with that before treatment (total contractility of the anterior vaginal wall: t=26.23, P<0.001; total contractility of posterior vaginal wall: t=39.02, P<0.001; the mean contractility of the anterior vaginal wall: t=17.92, P<0.001; the mean contractility of the posterior vaginal wall: t=22.57, P<0.001). At the same time, questionnaire score of international consultation on incontinent questionnaire short form (ICI-Q-SF scale) of 13 patients with combined mild to moderate stress urinary incontinence showed a statistically significant decrease compared with those before treatment (8.97±2.99 before treatment and (7.18±1.79) one month after treatment; t=2.792, P<0.01). Pelvic ultrasound and magnetic resonance examination indicated a tightening of the vaginal wall structure, and pelvic ultrasound observed a significant decrease in bladder neck mobility and a significant decrease in vesicourethral rotation angle. Vaginal tissue biopsy indicated an increase in the thickness of the vaginal mucosa and an increase in the number and more regular arrangement of collagen fibers after treatment. All patients had high treatment satisfaction and there were no adverse effects such as infection and bleeding during the treatment. Conclusions:Transvaginal CO 2 fractional laser treatment can improve the pelvic floor structure and function around the vagina, treat female vaginal laxity syndrome, stress urinary incontinence and female sexual dysfunction, with significant clinical efficacy and good safety.

OBJECTIVE To study the inhibitory effect and mechanism of total flavonoids from Melicope pteleifolia （TF-MPL） on transplanted tumor of colorectal cancer in nude mice. METHODS The transplanted tumor model of colorectal cancer was induced by injecting 0.2 mL colorectal cancer cell LoVo subcutaneously via the right armpit of nude mice. After successful modeling， nude mice were randomly divided into model group， 5-fluorouracil group （positive control， 10 mg/kg）， TF-MPL high- dose and low-dose groups （25， 12.5 mg/kg）； a normal group （normal saline containing 0.3% carboxymethyl cellulose sodium） without modeling was additionally set up， with 6 mice in each group. Each group was intraperitoneally injected with the corresponding drug solution/solvent for 21 consecutive days. The inhibitory rate of the transplanted tumor， liver and spleen index， and the levels of tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6） in serum were detected after the last medication； the morphological changes of tumor tissue were observed； immunohistochemical staining was used to detect protein expressions of Toll- like receptor 4 （TLR4） and nuclear factor-κB subunit p65 （NF-κB p65） in tumor tissue of nude mice. Western blot assay was used to detect protein expressions of TLR4， myeloid differentiation factor 88 （MyD88）， TNF receptor-associated factor 6 （TRAF6）， interleukin-1 receptor-associated kinase 1 （IRAK-1）， NF-κB p65 and caspase-3 in tumor tissue of nude mice. RESULTS Compared with the model group， TF-MPL high-dose group showed a significant decrease in tumor weight （inhibitory rate of 36.91%）， liver and spleen index， serum levels of TNF-α and IL-6 and protein expressions of TLR4， MyD88， TRAF6，IRAK-1 and NF- κB p65 （P＜0.05 or P＜0.01）； the expression of caspase-3 protein was increased significantly （P＜0.05）， and more tumor cell shrinkage and deformation， nuclear pyknosis and fragmentation were observed. CONCLUSIONS TF-MPL can significantly inhibit the growth of transplanted tumor of colorectal cancer in nude mice， the mechanism of which may be associated with reducing inflammatory response， inhibiting TLR4/MyD88/NF-κB signaling pathway， and promoting apoptosis in colorectal cancer cells.

Objective:To understand the changes in the practice environment from the perspective of doctors in 136 tertiary public hospitals, and to provide evidence for formulating strategies and measures to improve the practice environment of doctors.Methods:The data was collected from five rounds of China Healthcare Improvement Evaluation Survey from December 2015 to March 2021. The sample size was 17 945, 19 774, 20 786, 23 289, and 22 836, with a total of 104 630. The self-designed questionnaire on four dimensions of doctor-patient relationship, workload, administrative logistics support and professional identity was performed.Results:From the 1st to the 5th survey, the approval ratio of " the administrative and logistics department of this hospital is highly efficient" showed the characteristics of " U-shaped distribution" , and the approval ratio of " approve or encourage children to continue to engage in medical work" increased from 13.38% to 23.91%.From the 2nd to the 5th survey, the percentage of doctors who experienced doctor-patient disputes dropped from 28.96% to 23.20%, and the percentage of doctors agreeing that the relationship between doctors and patients in this hospital was improving continued to increase from 33.20% to 60.45%.From the 3rd to the 5th survey, the proportion of doctors experiencing medical troubles dropped from 15.10% to 14.19%, and the recognition rate of " the cafeteria of this hospital provided medical staff with nutritious and delicious meals" increased from 36.25% to 47.52%, and the approval proportion of " my current work load is heavy" dropped from 61.55% to 45.24%. The results of the 5th survey showed that there were significant differences in the approval ratios of each dimension in different genders, job titles and hospital types( P<0.001). Conclusions:From the perspective of doctor-patient relationship, workload, administrative logistics support, and professional identity, the improvement of doctors′ practice environment is still insufficient. Hospital administrators should continue to focus on the improvement of the doctor-patient relationship, and take necessary measures to reduce doctors′ workload and improve doctors′ professional identity.

Objective To observe the effects of tracer methodology when used to trace and manage emergency intravenous thrombolysis processes in patients with acute ischemic stroke (AIS). Methods The patients' attendance process was traced, improved and constantly optimized according to the theoretical basis of tracer methodology. A total of 112 AIS patients who received thrombolysis from September 2015 to August 2016 (before tracer methodology was implemented) were divided into the control group, while another 160 AIS patients who received thrombolysis between September 2016 and August 2017 (after tracer methodology was implemented). The time between arrival and thrombolysis administration and hospital treatment were compared between the two groups. Results After tracer methodology was carried out, the time used between arrival and admission by our stroke treatment team in the observation group was (4.1±1.2)min; the time between arrival and imaging examination was (18.8±11.2)min; the time between imaging examination and thrombolysis administration was (22.5±10.2)min; and the time between arrival and thrombolysis administration was (44.6±12.5)min, all shorter than that of the control group (P＜0.05). Conclusions The application of tracer methodology effectively reduces door to needle time, improves the efficiency of intravenous thrombolysis in AIS patients.

Objective To investigate and explore the awareness and willingness of breast cancer screening between Han and Mongolian women in Ordos, Inner Mongolia Autonomous Region, and to analyze the influence factors. Methods The patients answered investigation questionnaires face to face, and the content of questionnaire included demographic information, breast cancer awareness and relevant affecting factors on the awareness and willingness. Results 11162 (88.2 %) Han women and 1495 (11.8 %) Mongolian women were enrolled in the survey, with the average age of (45.4 ±7.1) years old and (45.4 ±6.8) years old. The education level (high school and above) of Han women was lower than that of Mongolian women [4456 women (40.0%) vs. 750 women (50.2%), χ2= 57.041, P< 0.001]. The Main way to delivery information on breast cancer screening in Han and Mongolian women was from their family members or friends [5002 women (44.9%) vs. 688 women (46.1%),χ2=40.699, P<0.001]. The proportions of never attending screening in the Han and Mongolian women were 41.7 % (4640 women) and 45.9 % (683 women), respectively (χ2=14.075, P=0.001). The breast self-examination rate of Han women were higher than that of Mongolian [71.1 % (7926 women) vs. 58.5 % (872 women), χ2= 98.466, P< 0.001]. According to logistics regression analysis, the cognitive level of women with high education level and breast disease history was higher (all P<0.001). Conclusions The cognitive level of breast cancer screening in Han women is better than that in the Mongolian, however, the overall level are low. It is necessary to strengthen the propaganda and education, and to encourage women to actively participate in breast cancer screening.
