OBJECTIVE To systematically evaluate the effects of oral non-peptidic thrombopoietin receptor agonists （TPO-RAs） on hepatic enzyme in adult patients with immune thrombocytopenia. METHODS A comprehensive literature search was conducted in PubMed， Web of Science， CNKI， Wanfang database and the Chinese Medical Association Journal Full-Text Database to collect randomized controlled trials （RCTs） comparing oral non-peptidic TPO-RAs （intervention group） with placebo or conventional therapy （control group）. All databases were searched from their inception to June 2025. After literature screening， data extraction and quality assessment of the included studies， meta-analysis was conducted using RevMan 5.4.1 software. RESULTS Twelve RCTs comprising 1 388 patients were included， with 971 in the intervention group and 417 in the control group. Meta-analysis results showed that there were no significant differences between the two groups in terms of the incidence of hepatic enzyme elevation[OR＝1.24， 95%CI （0.77， 1.99）， P ＝0.37 ] ， the incidence of hepatic enzyme elevation in patients treated for ≥6 weeks[OR＝1.21， 95%CI （0.73， 1.99）， P ＝0.46 ] ， and the incidence of severe hepatic enzyme elevation[OR＝1.39， 95%CI（0.46， 4.20）， P ＝0.55 ] . Subgroup analysis showed that there were no significant differences in the incidence of hepatic enzyme elevation between the intervention group and control group among patients using eltrombopag[OR＝1.57，95%CI（0.85，2.87）， P ＝0.15 ] ， avatrombopag[OR＝0.88，95%CI （0.09，8.46）， P ＝0.91 ] ， and hetrombopag[OR＝1.04，95%CI（0.30，3.65）， P ＝0.95 ] ， respectively. CONCLUSIONS Oral non-peptidic TPO-RAs do not significantly increase the risk of hepatic enzyme elevation in adult patients with immune thrombocytopenia， and show an overall favorable hepatic safety profile.

Medical humanities consistently run through the entire process of medical development and educational reform. However， with the increasingly prominent dominance of evidence-based medicine in clinical practice， the medical humanities have gradually been weakened in both medical education and clinical practice. Narrative medicine， through telling and listening to patients’ stories， enhances healthcare professionals’ empathy， fosters doctor–patient communication， and facilitates a return to the humanistic essence of medical education and clinical practice. By sorting out and reviewing related literature and developmental trends both at home and abroad， this paper pointed out the existing structural problem of an imbalance between technological priority and humanistic care in medical education， focusing on how to achieve an effective integration of medical humanities and narrative medicine in medical education. This paper also systematically analyzed the significance of both medical humanities and narrative medicine in the medical education system and proposed promoting the deep embedding of narrative medicine in medical education from three entry points， namely， curriculum integration， interdisciplinary collaboration， and the construction of teaching evaluation systems. The aim was to provide theoretical support and practical experience for medical education reform， foster the coordinated development of professional competence and humanistic spirit among medical talents， and truly achieve the goal of cultivating well-rounded medical talents.

Objective To evaluate the radiation dose levels induced by secondary neutrons at different locations inside proton therapy treatment rooms, and analyze the distribution characteristics of neutron energy spectra by combining experimental measurements with simulations, and to provide a theoretical basis and technical support for radiation protection design and management in proton therapy. Methods Multiple representative measurement points were established in the treatment rooms of two hospital-based proton therapy centers. The DIAMON neutron spectrometer was employed to perform in-situ measurements of secondary neutron doses and energy spectra. Three-dimensional simulation models of treatment rooms were constructed using the FLUKA code to simulate the generation and transport of secondary neutrons. Results Measurements showed that the neutron dose was highest near the target region, reaching up to 4293.750 µSv/h. The doses at the maze entrance were the next highest, ranging from 422.091 to 489.268 µSv/h, while the doses in the middle section of the maze ranged from 2.860 to 6.727 µSv/h. The neutron energy spectra exhibited a triple-peak pattern. Conclusion Significant accumulation of secondary neutrons was observed near the target and in the maze regions during proton therapy, with intermediate-energy neutrons being the dominant dose contributor. The consistency between measurements and simulations validated the reliability of the model, which can provide a basis for optimizing treatment room shielding and controlling occupational exposure for staff.

Objective To investigate the microbial disinfection and sterilization effectiveness of an electron linear accelerator on the surface and interior of postal packages, and to design and conduct a penetrating radiation disinfection and sterilization experiment. Methods This experiment selected Bacillus pumilus E601 (ATCC 27142) as the indicator microbial strain for radiation. An experimental model of postal package was subjected to penetrating radiation with different dose gradients using high-energy electron beams generated by an S-band 10 MeV electron linear accelerator. The disinfection and sterilization effectiveness was assessed by culturing and counting B. pumilus after high-energy electron beam radiation treatment. A control group was established to analyze the influence of actual absorbed doses at different gradients on the disinfection and sterilization effectiveness of the electron linear accelerator. Results The actual absorbed doses of high-energy electron-beam radiation required to achieve 1-, 3-, and 6-log reductions of B. pumilus were 1.63, 5.07, and 10.22 kGy, respectively. Complete inactivation was achieved at an absorbed dose of 10.92 kGy, which met the processing requirements specified in the technical standard for ionizing-radiation disinfection. Conclusion The experimental data indicated that the actual absorbed dose for B. pumilus is linearly positively correlated with the log reduction of bacterial colonies killed by electron beam radiation. For disinfection and sterilization requirements in different scenarios, the required actual absorbed dose can be achieved by dynamically adjusting the operating speed of the under-beam transmission system.

OBJECTIVE To investigate the actual construction and operation status of established and under-construction centralized （cloud） prescription review centers （shortened for “prescription review center”） of close-knit county-level medical consortium in a certain city， so as to provide reference for improving the construction quality of the prescription review center. METHODS An online questionnaire survey was conducted to collect the data from 51 established and under-construction prescription review center in the city， covering basic information， funding sources， talent management， system construction， review rule maintenance， prescription review practices， prescription evaluation， data utilization， and current challenges. The collected data were summarized and analyzed. RESULTS A total of 51 valid questionnaires were retrieved， covering 32 established and 19 under-construction prescription review center. Among the 32 established prescription review centers， the main funding sources for their construction came from government financial allocations， accounting for 56.25%. Only 25.00% of prescription review center had review pharmacists who fully met national qualification requirements， and just 55.00% updated more than 10 review rule entries per month on average. Outpatient prescription verification realized full coverage， but 37.50% of prescription review centers only supported rationality verification of single prescriptions， and 50.00% could not retrieve laboratory and examination results to assist in prescription review. Additionally， 40.62% of prescription review center had not regularly conducted prescription evaluations for primary care institutions. The data from prescription review center was mainly used to support medication monitoring. Among the 19 prescription review centers currently in the planning stage， 63.16% had no identified funding sources. CONCLUSIONS The operation and construction of prescription review center in the city face challenges， such as funding shortages， absence of collaborative incentive mechanisms， and insufficient manpower.It is suggested that the state should issue a unified standard for the construction of the prescription review center as soon as possible， and local health administrative departments should formulate supporting policies and clarify assessment indicators in combination with the actual situation of the region.

OBJECTIVE To investigate the ameliorative effect and mechanism of short-acting exenatide on diabetic cognitive dysfunction. METHODS Spontaneously diabetic db / db mice were randomly divided into model group （normal saline） and exenatide group （50 μg/kg）， with db / m mice as the normal control group （normal saline）， with 8 mice in each group. Mice in each group were subcutaneously injected with corresponding drugs or normal saline twice daily for 8 consecutive weeks. Body weight and fasting blood glucose were measured at a fixed time every week. Cognitive function was evaluated by Morris water maze test. The levels of oxidative st ress indicators [malondialdehyde （MDA）， superoxide dismutase （SOD）， glutathione （GSH） ] ， cyclic adenosine monophosphate （cAMP） and protein kinase A （PKA） were detected in hippocampus tissue of mice. The hippocampal neuronal HT22 cells of mice were divided into control group （25 mmol/L glucose）， high glucose group （125 mmol/L glucose）， high glucose+exenatide group （125 mmol/L glucose+20 nmol/L exenatide）， high glucose+exenatide+H89 （PKA inhibitor） group （125 mmol/L glucose+20 nmol/L exenatide+10 μmol/L H89）， and high glucose+H89 group （125 mmol/L glucose+10 μmol/L H89）. After 48 h of intervention with corresponding solutions/culture medium， the levels of oxidative stress indicators， cAMP and PKA， the activities of mitochondrial respiratory enzymes Ⅱ and Ⅳ， and the phosphorylation level of dynamin-related protein 1 （Drp1） were measured. RESULTS Animal experiments showed that compared with the normal control group， the model group exhibited significantly increased body weight， fasting blood glucose and MDA level in the hippocampus （ P ＜0.05）， as well as significantly prolonged escape latency （ P ＜0.05）； swimming speed significantly slowed down， the time spent in the target quadrant， the number of platform crossings， and the levels of SOD， GSH， cAMP and PKA in the hippocampus were significantly decreased （ P ＜0.05）. Compared with model group， all the above indicators （except for swimming speed） in the exenatide group were significantly reversed （ P ＜0.05）. Cell experiments showed that compared with high glucose group， the high glucose+exenatide group had significantly decreased MDA level （ P ＜0.05）， and significantly increased levels of SOD， GSH， cAMP and PKA， the activities of mitochondrial respiratory enzymes Ⅱ and Ⅳ， and phosphorylation level of Drp1 （ P ＜0.05）. Compared with high glucose+exenatide group， the above indicators in the high glucose+exenatide+H89 group were significantly reversed （ P ＜0.05）. CONCLUSIONS Short-acting exenatide can activate the cAMP/PKA pathway， promote Drp1 phosphorylation， and increase the activities of mitochondrial respiratory enzymes， thereby maintaining mitochondrial stability， reducing oxidative stress injury， and ultimately improving diabetic cognitive dysfunction.

OBJECTIVE To prepare an intelligent responsive liposome-hydrogel nanopreparation co-loaded with gambogic acid （GA）， and characterize its antitumor activity in vitro . METHODS GA-ICG-Lip-gel was prepared by ethanol injection and cold dissolution， incorporating GA and the photosensitizer indocyanine green （ICG）. The appearance and microscopic morphology of GA-ICG-Lip-gel were observed， its encapsulation efficiency and drug loading capacity were measured， and its photothermal conversion performance， photothermal stability， and infrared imaging properties were investigated， along with the determination of its in vitro release profile. Human breast cancer MCF-7 cells were used as objects to investigate the effects of GA-ICG-Lip-gel （or with near-infrared light irradiation） on cell viability， migration ability， and the cellular uptake capacity of GA-ICG-Lip-gel. RESULTS GA-ICG-Lip-gel existed in a solution state at room temperature and transformed into a gel state at 37 ℃. Its microstructure was dense with small pores， and its encapsulation efficiency and drug loading were （96.07±0.86） % and （6.28±1.16） %， respectively. After exposure to near-infrared light， the temperature of GA-ICG-Lip-gel rose above 42 ℃， with no significant attenuation observed in the heating curve. The heating efficiency was dependent on both the irradiation time and drug concentration. Compared to media without gelatinase， the cumulative release rate of GA-ICG-Lip-gel increased in media containing gelatinase. In vitro studies showed that GA-ICG-Lip-gel could be efficiently taken up by MCF-7 cells； GA-ICG-Lip-gel significantly inhibited the viability and migration ability of MCF-7 cells （ P ＜0.05）， and this inhibitory effect was further enhanced under near-infrared light irradiation. CONCLUSIONS This study successfully prepares GA-ICG-Lip-gel， which exhibits favorable photothermal conversion properties and temperature/enzyme dual-responsive drug release characteristics， and demonstrates significant inhibitory effects on the proliferation and migration of breast cancer cells.

Objective: To investigate the preventive and reparative mechanisms of platelet-rich plasma-biodegradable quick setting spray (PRP-BQSS) on solar dermatitis, thereby providing a safe and effective novel therapeutic approach for clinical application. Methods: PRP-BQSS was prepared. A ultraviolet B (UVB)-induced solar dermatitismodel was established in SPF-grade male SD rats. The rats were divided into the prevention experiment (treated with PRP-BQSS, L' Oréal SPF 50+sunscreen, Nature's Hall SPF 50+sunscreen, or saline) and the treatment experiment (treated with PRP-BQSS, Jingwanhong ointment, Green ointment, or saline). The effects were evaluated by measuring epidermal thickness (HE staining) and quantifying the integrated optical density (IOD) of inflammatory cells (CD11b staining). One-way ANOVA and Tukey's HSD test were performed using GraphPad Prism 9.4.0. Results: The PRP-BQSS exhibited significant efficacy in both prevention and repair. In the prevention experiment, the PRP-BQSS prevention group (Group A) showed only mild pale red erythema on the dorsal skin of rats, without significant swelling or desquamation. Histological analysis revealed that epidermal thickness in Group A (36.55±6.58 μm) was comparable to Groups B (L' Oréal, 34.84±6.59 μm) and C (Natural Hall, 34.59±8.20 μm)(P>0.05), but significantly lower than that in Group D (control group, 47.82±11.69 μm). Skin sections from Group A demonstrated intact epidermal structure with clear stratification and no significant inflammatory cell infiltration. The CD11b-positive cell count (24.30±7.43) was significantly lower than that in Group D (33.65±8.47, P<0.05). In the treatment experiment, HE staining of Group A (PRP-BQSS treatment group) showed intact epidermal structure with orderly arrangement of the basal layer, spinous layer, and granular layer, thin and uniform stratum corneum, and regular collagen fiber arrangement. The epidermal thickness of Group A (37.10±6.41 μm) showed no significant difference from Groups B (Jingwanhong ointment group, 38.66±9.07 μm) or C (Green ointment group, 35.72±4.98 μm)(P>0.05), but was significantly lower than that in Group D (control group, 48.35±8.99 μm)(P<0.05). The integral optical density value of CD11b-positive cells in Group A (32.82±11.01) was significantly lower than that in Group D (47.25±13.52, P>0.05). Moreover, the degree of inflammatory infiltration in Group A was relatively lower compared to Group B (37.14±9.20) and Group C (34.32±16.87), suggesting a superior repair capacity. However, the intergroup differences were not statistically significant (P>0.05). Conclusion: PRP-BQSS hydrogel dressing possesses dual preventive and reparative functions. It exerts its effects by reducing CD11b-positive cell infiltration (inflammation suppression) and promoting the orderly arrangement of the basal layer-epidermal layer-granular layer (epidermal reconstruction). This material holds promise as a novel and effective therapeutic approach for the prevention and treatment of solar dermatitis, particularly suitable for high-risk populations such as children, individuals with sensitive skin, and those engaged in outdoor activities.

Objective: To characterize the serological profile, RHD genetic spectrum, and their frequencies among pregnant women preliminary screened as RhD-negative and weak positive in Qingdao and surrounding areas, and correlate these findings with unexpected antibody detection results, thereby providing testing recommendations and suggestions for such individuals. Methods: Blood samples of pregnant women who were initially identified as RhD negative and weak positive in hospitals in Qingdao and surrounding areas over the past five years were collected. Different cloned IgG anti-D antibodies were used for RhD negative confirmation experiments. RHD genotyping was performed by combining PCR-SSP and Sanger sequencing. Unexpected antibody screening and identification were carried out using test tube method and microcolumn gel card. The immunologic status of newborns delivered by anti-D pregnant women was also tracked. Results: A total of 602 blood samples were collected from pregnant women initially identified as RhD-negative and weak positive. Among them, 569 (94.5%) were confirmed as RhD-negative in the RhD confirmation test, and 33 (5.5%) were D variant phenotype. Except for 4 cases where no definite mutations were found, gene analysis revealed 474 (78.7%) D-negative cases with 5 genotypes (RHD 01N.01, RHD 01N.03, RHD 01N.16, RHD 01N.05, and 1 new allele), 90 (15.0%) Del cases with 2 genotypes (RHD 01EL.01, and RHD 01EL.18), 23 (3.8%) weak D cases with 2 genotypes (RHD 15 and 1 new allele), and 11 (1.8%) partial D cases with 2 genotypes (RHD 06.03.01 and RHD 05.04). Anti-D and complex antibodies containing anti-D were detected in 96 RhD-negative and partial D pregnant women (15.9%). After injection of anti-D immunoglobulin, One O-type RhD-negative pregnant woman delivered a newborn with hyperbilirubinemia. The newborn was typed to be B Del, and anti-D was detected in both serum and eluate. Conclusion: The serological profiles, RHD gene types and frequencies among RhD negative pregnant women in Qingdao and surrounding areas are basically consistent with domestic published data. Pregnancy can stimulate anti-D production in D-negative and partial D individuals. However, anti-D antibody has not been detected in Del type pregnant women. Since anti-D immunoglobulin can binds to Del type red blood cells, its administration is not recommended for Del type pregnant women.

ObjectiveTo investigate the mechanism of Zuogui Wan （ZGW） in improving ovarian inflammatory microenvironment and stemness of ovarian germline stem cells （OSCs） for treating ovarian aging via the cyclic guanosine monophosphate/adenosine monophosphate synthase （cGAS）/stimulator of interferon genes （STING） signaling pathway. MethodsForty C57BL/6 female mice were randomly divided into a blank group， a model group， a low-dose ZGW group （2.7 g·kg^-1）， a high-dose ZGW group （5.4 g·kg^-1）， and an estradiol valerate group （0.15 mg·kg^-1）， with 8 mice in each group. Except the blank group， all other groups received a single intraperitoneal injection of cyclophosphamide at 120 mg·kg^-1 to establish an ovarian aging mouse model. After successful modeling， each group was continuously administered for 4 weeks， once daily. The physiological status of the mice was observed， and the ovarian index was calculated. The estrus cycle of the mice was monitored. Hematoxylin-eosin （HE） staining was used to observe pathological changes in ovarian tissue. Enzyme-linked immunosorbent assay （ELISA） was used to detect serum sex hormone levels. Serum inflammatory factors interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， and mouse interleukin-6 （IL-6） levels were detected using kits. Western blot was used to detect the protein expression of ovarian cGAS， STING， p-STING， TANK-binding kinase 1 （TBK1）， p-TBK1， interferon-induced transmembrane protein 3 （Fragilis）， and Vasa homolog protein （MVH）. Quantitative real-time polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of inflammatory factors in ovarian tissue. Immunofluorescence double labeling was performed to locate OSCs in ovarian tissues， and fluorescence intensities of OSCs markers MVH and octamer binding transcription factor 4 （Oct4） were calculated. ResultsCompared with the blank group， the model group showed reduced body weight， ovarian wet weight， and ovarian index （P<0.01） and a disordered estrus cycle （P<0.01）. In addition， the levels of serum follicle-stimulating hormone （FSH）， TNF-α， IL-6， and IL-1β were increased （P<0.01）， while anti-Müllerian hormone （AMH） and estradiol （E₂） levels were decreased （P<0.01）. The protein expression of cGAS， p-STING/STING， and p-TBK1/TBK1 in ovarian tissue was increased （P<0.05， P<0.01）， while that of OSCs stemness factors MVH and Fragilis was reduced （P<0.01）. Immunofluorescence indicated a reduction in MVH and Oct4 expression in OSCs （P<0.01）. The mRNA expression of inflammatory factors TNF-α， IL-6， and IL-1β in ovarian tissue was increased （P<0.05， P<0.01）. Compared with the model group， the treatment groups exhibited improved body weight， ovarian wet weight， and ovarian index （P<0.05） and a reduced rate of estrus cycle disorder （P<0.05， P<0.01）. The levels of serum FSH， TNF-α， IL-6， and IL-1β were decreased （P<0.05， P<0.01）， while AMH and E₂ levels were increased （P<0.01）. The protein expression levels of cGAS， p-STING/STING， and p-TBK1/TBK1 in ovarian tissue were decreased （P<0.05）， while the protein expression of MVH and Fragilis was increased （P<0.05）， and the fluorescence intensities of MVH and Oct4 were increased （P<0.05， P<0.01）. The mRNA expression of inflammatory factors in ovarian tissue was decreased （P<0.05）. ConclusionZGW alleviate ovarian inflammatory response， regulate ovarian microenvironment homeostasis， and maintain stemness of OSCs in ovarian aging mice probably by modulating the cGAS-STING signaling pathway， thereby improving ovarian function and delaying ovarian aging.
