OBJECTIVE To systematically review the status on pharmacist competency assessment tools both domestically and internationally， providing a theoretical basis for constructing scientific and applicable pharmacist competency assessment tools in China. METHODS Through literature review and comparative analysis， 15 representative domestic and international pharmacist competency assessment tools were systematically summarized， and their theoretical foundations， core dimensions， methodological characteristics and practical applications were compared and implications were given. RESULTS &CONCLUSIONS International research has established relatively mature evaluation systems. Represented by those developed from the United Kingdom， the United States， and the International Pharmaceutical Federation， these assessment tools demonstrate scientific structure， wide application， and dynamic and international applicability. While domestic research has progressed in sub-specialties such as clinical pharmacists， licensed pharmacists and pediatric pharmacists， it still faces challenges including insufficient standardization， inadequate validation， delayed updates， and limitations in practical application. The reasons for the disparities in assessment tools between China and other countries include differences in pharmaceutical care models， varying pharmacist training systems， cultural and social background factors， as well as differences in industry management and international influence. Based on this， the author suggests promoting the development and research of assessment tools for pharmacist job competency in China from four aspects： mechanism construction， system refinement， standardization development， and practical implementation.

Bruch's membrane opening(BMO)is the true anatomical border of the optic nerve head and provides higher anatomical accuracy, structural stability and measurement repeatability than traditional assessments based on the clinically visible optic disc margin. Optical coherence tomography(OCT)serves as a key technical tool for quantitative assessment of BMO-associated structural parameters. With the development of spectral-domain OCT(SD-OCT)and swept-source OCT(SS-OCT), parameters such as BMO-minimum rim width(BMO-MRW), BMO-minimum rim area(BMO-MRA), BMO area, offset, tilt, and torsion have emerged as important imaging biomarkers for evaluating optic nerve head morphology and for assisting in the diagnosis, staging, and longitudinal monitoring of glaucoma, myopia, and pathological myopia. Traditionally, the acquisition of these parameters has relied heavily on manual segmentation, which is limited by low efficiency, strong subjectivity, and considerable inter-observer variability. In recent years, artificial intelligence has been increasingly applied to OCT image segmentation, quality control, cross-device calibration, and automated quantitative analysis, thereby improving efficiency, objectivity, and reproducibility, particularly in eyes with complex optic disc morphology. This review summarizes recent advances in the BMO-related terminology standardization, imaging and quantitative methodologies, quality control,artificial intelligence-assisted analysis, as well as clinical evidence of its application in glaucoma, myopia and pathological myopia. Particular emphasis is placed on their potential value in the differential diagnosis and follow-up evaluation of highly myopic eyes with glaucoma, aiming to provide a reference for the standardized clinical application and future translational use of BMO-related parameters.

The blood-brain barrier(BBB)plays a crucial role in maintaining the special microenvironment of brain tissue,which promotes the exchange of substances while separating the peripheral circulatory system from the brain parenchyma.However,normal aging and neurodegenerative diseases can alter and disrupt the physiological properties of the BBB.This review provides a brief introduction to the interrelationship and pathogenic mechanisms between Alzheimer's disease(AD)and BBB dysfunction,and explores current research status and BBB-targeted pharmacotherapy for AD,providing new ideas for the prevention and treatment of AD.

Hepatocellular carcinoma is one of the malignant tumors with a high mortality rate in China.Most of them were found in the middle and late stage,and missed the opportunity of surgery.Early diagnosis and treatment can significantly improve the prognosis of patients.With the development of ultrasound molecular imaging technology,targeted contrast-enhanced ultrasound provides a new technical means for the diagnosis and treatment of hepatocellular carcinoma.The application progresses of targeted ultrasound contrast imaging in diagnosis and treatment of hepatocellular carcinoma are reviewed in this article.

Objective To explore the effects of different CO2 pneumoperitoneum pressures during surgery on overweight or obese patients with laparoscopic panhysterectomy in Trendelenburg position.Methods A total of 88 overweight or obese patients who underwent laparoscopic panhysterectomy were selected and randomly divided into the low-pressure group and the high-pressure group according to random number table method,with 44 patients in each group.All patients used CO2 as the pneumoperitoneum medium during surgery,with 10 mmHg of CO2 pneumoperitoneum pressure in the low-pressure group and 15 mmHg of CO2 pneumoperitoneum pressure in the high-pressure group.The operation-related indexes,respiratory indicators,nasopharyngeal temperature and adverse reactions of patients were compared between the two groups.Results There was no significant difference in the surgical time,blood loss,intraoperative infusion volume,incidence of organ injury,and laparotomy rate between the two groups(P>0.05).The recovery time of anesthesia of patients in the low-pressure group was shorter than that in the high-pressure group(P<0.05).At 30 minutes after the establishment of pneumoperitoneum,the peak airway pressure(Ppeak)and plateau pressure(Pplat)of patients in the high-pressure group were significantly higher than those in the low-pressure group(P<0.05),while the dynamic lung compliance(Cdyn)of patients in the high-pressure group was significantly lower than that in the low-pressure group(P<0.05).At 60 minutes after the establishment of pneumoperitoneum and the end of pneumoperitoneum,the nasopharyngeal temperature of patients in the high-pressure group were significantly lower than those in the low-pressure group(P<0.05).The incidences of intraoperative hypothermia and shivering in the high-pressure group were significantly higher than those in the low-pressure group(P<0.05).Conclusion Compared with 15 mmHg of CO2 pneumoperitoneum pressure,10 mmHg of CO2 pneumoperitoneum pressure on overweight or obese patients with laparoscopic panhysterectomy in Trendelenburg position does not increase surgical difficulty,and the patients has lower airway pressure,better lung compliance,fewer adverse reactions,and faster recovery,which can also avoid intraoperative hypothermia.

Background: Diabetes-induced testicular damage (DITD) is a common complication of diabetes. We investigated underlying mechanism of retinoblastoma-binding protein 6 (Rbbp6)-mediated brain and muscle ARNT-like 1 (Bmal1) ubiquitination in modulating ferroptosis in DITD. Methods: Spermatogenic cell apoptosis and viability were measured by flow cytometry and cell counting kit 8 (CCK-8), respectively. The impact of Rbbp6 and Bmal1 on ferroptosis was assessed by determining expression of ferroptosis markers glutathione peroxidase 4 (GPX4) and solute carrier family 7 member 11 (SLC7A11), and levels of malondialdehyde (MDA), glutathione (GSH), iron, and lipid peroxidation. Co-immunoprecipitation was performed to determine the interaction between Rbbp6 and Bmal1, as well as the ubiquitination level of Bmal1. The expression levels of Rbbp6, Bmal1, Yes-associated protein 1 (YAP1), ferroptosis markers, and testicular steroidogenic enzymes were tested by Western blot. Results: Bmal1 protein expression was significantly downregulated, while Rbbp6 was upregulated in DITD mouse model and high glucose (HG)-induced GC-1 spg cells. Overexpression of Bmal1 improved testicular injury in diabetic mice, reduced 4-hydroxynonenal (4-HNE), MDA, iron levels, and increased expression levels of GPX4, SLC7A11, GSH, as well as testicular steroidogenic enzymes. Rbbp6 decreased Bmal1 level through promoting its ubiquitination. Meanwhile, Rbbp6 knockdown inhibited the ferroptosis of HG-induced GC-1 spg cells, which were abolished by silencing Bmal1. In addition, knockdown of YAP1 or treatment with ferroptosis inducer erastin blocked the above effects caused by Bmal1 overexpression. Conclusion Rbbp6-mediated Bmal1 ubiquitination suppressed YAP1 pathway, promoting ferroptosis in DITD. This study highlighted Rbbp6/Bmal1/YAP1 axis as a potential therapeutic target for mitigating DITD.

Objective To investigate the anatomical and microscopic structures of interstitial fluid flow channels in the skin tissue of hand dorsum in human cadavers.Methods Totally 7 fresh cadavers within 12 hours post-mortem were included.MRI was used to observe the distribution of interstitial fluid flow from the first phalanx of the fingers to the wrist,precisely locating the flow channels.Based on imaging results,histological analyses were conducted to determine the histological characteristics of the flow channels.Furthermore,multi-immunofluorescence and microcomputed tomography(Micro-CT)techniques were employed to analyze the channels,and image post-processing was used to elucidate their anatomical structures at the microscopic level.Results After injecting a contrast agent into the first phalanx of ten finger specimens and applying repeated pressure,MRI image revealed centripetal long-range interstitial fluid flow along channels distinct from blood vessels and lymphatic vessels.Histological analysis and Micro-CT further confirmed that the flow primarily occurred within the fibrous connective tissue and adventitia of the skin.Conclusion The orderly fibrous connective tissue and adventitia in the skin form the interstitial fluid flow channels in the human hand dorsum skin,named as"stromal membrane channels"in the skin.
