OBJECTIVE To explore the characteristics and influential factors of pharmaceutical clinic service demands， providing evidence for optimizing pharmaceutical service models and facilitating pharmaceutical service models of pharmacist role transformation. METHODS A cross-sectional survey design was adopted， and 410 outpatient participants were selected from Fudan University Shanghai Cancer Center through convenience sampling for questionnaire administration from February to May 2025. Kano model was applied to analyze the demand attributes of 25 pharmaceutical services， while questionnaires were used to assess patients’ awareness and demand status. Subgroup analyses were conducted based on key demographic variables such as gender， age， educational attainment， and economic burdens， to SACA- systematically examine the differences in Kano attribute classification among patients in each subgroup. RESULTS The awareness rate of pharmaceutical outpatient services among patients was only 14.63%， yet those who were aware demonstrated a significantly higher demand rate for such services compared to those who were unaware （P＜0.001）. The demand for pharmaceutical clinic services exhibited a hierarchical characteristic： twelve items were identified as attractive attributes （e. g.， providing suggestions for more affordable treatment options， offering online consultation services， etc.）， five items as expected attributes （e.g.， having a good attitude and being able to patiently answer your questions， etc.）， three items as must-have attributes （e.g.， providing guidance on medication dosage and usage， providing guidance on medication precautions， etc.）， five items as indifferent attributes （e.g.， providing treatment plan recommendations based on the patient’s condition）. There were zero items classified as reverse attribute. Subgroup analysis revealed that female patients showed greater concern for “neat and clean attire of medical staff” than male patients （P＜0.001）； patients under 60 years of age demonstrated stronger demand for “providing treatment plan recommendations based on patients’ conditions” compared to patients aged 60 or above （P＝0.016）； those with below high school education placed greater emphasis on “providing guidance on medication precautions” compared to those with a high school education or above （P＝0.011）； patients with lower economic burdens exhibited stronger preferences for “neat and clean attire of medical staff ” （P＝0.002）. CONCLUSIONS The public awareness rate of pharmaceutical clinic services is considerably low； however， those who are aware of such services demonstrate significantly higher demand. The medication safety-related services and convenience-oriented demands should be prioritized in the development of pharmaceutical clinics. Moreover， the study also revealed that factors such as gender， age， educational level， and economic burdens exert significant influences on patients’ service demands.

Objective:To evaluate the effect of urethral stent tube irrigation in preventing postoperative complications in adolescents with hypospadias.Methods:A retrospective analysis was conducted using the clinical data of adolescents with hypospadias treated at the Department of Urology, Children’s Hospital of Chongqing Medical University, from April 2016 to July 2023. Patients were divided into control group and study group according to whether urethral stent tube was inserted in urethra during operation. All surgeries were performed by the same surgeon. For two days before surgery, patients were instructed to cleanse the surgical site daily with body wash and a 5% povidone-iodine solution. In the control group, patients received postoperative care with an indwelling urinary catheter. In the study group, in addition to the urinary catheter, a urethral stent tube was placed in the posterior urethra, and postoperative urethral irrigation with saline was performed. Postoperative complications, including wound infection, urethral fistula, urethral stricture, and urethral diverticulum, were monitored. Categorical data were expressed as frequencies and percentages and were analyzed using the χ2 test or Monte Carlo-based χ2 test. Continuous data with normal distribution are presented as Mean±SD and were analyzed using the t-test. Non-normally distributed continuous data were expressed as M ( Q1, Q3) and were analyzed using the Wilcoxon rank-sum test. P<0.05 was considered statistically significant. Results:A total of 76 patients were enrolled in the study, with 43 patients in the control group [median age 12.9(12.2, 13.7) years, reconstructed urethral length (3.88±1.86) cm] and 33 patients in the study group [median age 12.5(11.3, 14.1) years, reconstructed urethral length (3.30±1.45)cm]. Postoperatively, 32 patients (74.4%) in the control group experienced complications, including 24 cases (55.8%) of wound infection, 16 cases (37.2%) of urethral fistula, 6 cases (14.0%) of urethral stricture, and 2 cases (4.7%) of diverticulum. In the study group, only 1 patient (3.0%) developed both wound infection and urethral fistula. The incidence of wound infection, urethral fistula, and overall complications was significantly lower in the study group than in the control group (all P<0.01). Conclusion:Postoperative urethral stent irrigation in adolescents with hypospadias significantly reduces the incidence of wound infection and urethral fistula.

Calcium-based biomaterials have been intensively studied in the field of drug delivery owing to their excellent biocompatibility and biodegradability. Calcium-based materials can also deliver contrast agents, which can enhance real-time imaging and exert a Ca²⁺-interfering therapeutic effect. Based on these characteristics, amorphous calcium carbonate (ACC), as a brunch of calcium-based biomaterials, has the potential to become a widely used biomaterial. Highly functional ACC can be either discovered in natural organisms or obtained by chemical synthesis However, the standalone presence of ACC is unstable in vivo. Additives are required to be used as stabilizers or core-shell structures formed by permeable layers or lipids with modified molecules constructed to maintain the stability of ACC until the ACC carrier reaches its destination. ACC has high chemical instability and can produce biocompatible products when exposed to an acidic condition in vivo, such as Ca²⁺ with an immune-regulating ability and CO₂ with an imaging-enhancing ability. Owing to these characteristics, ACC has been studied for self-sacrificing templates of carrier construction, targeted delivery of oncology drugs, immunomodulation, tumor imaging, tissue engineering, and calcium supplementation. Emphasis in this paper has been placed on the origin, structural features, and multiple applications of ACC. Meanwhile, ACC faces many challenges in clinical translation, and long-term basic research is required to overcome these challenges. We hope that this study will contribute to future innovative research on ACC.

Objective: The research was aimed at exploring the effects of mandelic acid on the proliferation , apoptosis and migration of H1299 lung adenocarcinoma (LUAD) cells and the related molecular mechanisms. Methods: CCK⁃8 was used to detect changes in the proliferation ability of H1299 cells;Hoechst 33258/PI double⁃staining assay was used to analyze the apoptosis of H1299 cells;Transwell and migration assays were used to analyze changes in the invasive and migration ability of H1299 cells;Western blot was used to detect the expression of proliferation ,apoptosis and migration⁃related pathway proteins. Results : Different concentrations of mandelic acid inhibited the proliferation viability and invasion and migration ability of H1299 cells (P < 0. 05) . Mandelic acid induced high expression of bax and cl⁃caspase⁃3 and low expression of p ⁃stat3 in proliferation and apoptosis pathways (P < 0. 05) .In addition , it inhibited the expression of MMP⁃9 and Vimentin proteins ,which were related to invasion and migration (P < 0. 01) . Conclusion Mandelic acid inhibited the proliferation of H1299 LUAD cells and elevated the level of apoptosis , and molecular biological mechanism might be closely related to the decreased activation of stat3 and activation of bax/caspase⁃3 signaling axis. The inhibition of invasive and migrational ability of H1299 cells induced by mandelic acid was associated with the decreased expression of MMP⁃9 and Vimentin proteins.

Dual target therapy of dabrafenib combined with trametinib (DabTram) plays an important role in the treatment of malignancies. Ocular toxicities are adverse reactions which are relatively uncommon but potentially serious in DabTram treatment. At present, there is a lack of systematic research on ocular toxicities caused by DabTram, leading to insufficient understanding of this problem. In this paper, the literature on DabTram-related ocular toxicities are systematically reviewed, especially focusing on the incidence, clinical characteristics, mechanisms of occurrence, therapeutic measures and so on, and the corresponding management pathways in clinical medication were proposed to provide references for safe use of DabTram in clinic.
