OBJECTIVE To establish a pharmaceutical management model for infusion safety in hospitalized inpatients and ensure the safety of drug use. METHODS Our hospital established the standardized management process for infusion scheme， formulated rules for compatibility contraindications in drug combinations. In the form of embedded hospital official account, the infusion scheme and medication guidance WeChat developed by pharmacists are pushed to the mobile phone of inpatients, providing electronic medication guidance services for patients, and forming a pharmaceutical management model for infusion safety of inpatients. RESULTS Our hospital provided a total of 45 291 inpatients with pharmaceutical services including the formulation of individualized infusion scheme and WeChat push infusion scheme and medication guidance as of December 2023. After the implementation of the management model， the intervention rate of pharmacists on the compatibility contraindications in drug combination of long-term medical orders for inpatients increased from 18.25% before implementation to 90.58% （P＜0.01）， and the satisfaction rate of inpatients increased from 87.50% to 94.50% （P＜0.05）. CONCLUSIONS The pharmaceutical management model for infusion safety of hospitalized patients integrates pharmaceutical services throughout the entire process of intravenous medication treatment. Pharmacists can participate in the management of infusion usage while providing qualified finished infusion products, achieving closed-loop management of pharmaceutical services, improving the hospital’s pharmaceutical service capabilities and patient satisfaction, and providing guarantees for the safety and effectiveness of patient medication.

OBJECTIVE To analyze the traditional Chinese medicine （TCM） emergency management policy texts in China， reveal the characteristics， problems and improvement directions of Chinese medicine emergency management policies in China， and provide references and lessons for improving the level of Chinese medicine emergency management. METHODS Twenty-four TCM emergency management policy texts issued at the central level from 2016 to 2023 were coded and analyzed using Nvivo11 software to construct a three-dimensional analysis framework based on policy tools， stakeholders and policy strength. RESULTS In the policy tools dimension， the environmental type was the most （46.74%）， the supply type was the second （31.80%）， and the demand type was the least （21.46%）； in the stakeholder dimension， there were more healthcare institutions （40.63%） and government departments （31.25%）， and fewer healthcare workers （14.84%） and residents （13.28%）； in the policy strength dimension， the overall policy strength was poor， and the differences in effectiveness across policy instruments and stakeholders were more significant. The cross-cutting results showed that there was a certain degree of mismatch in policy instruments， stakeholders and policy strength. CONCLUSIONS The use of supply-oriented policy tools is slightly lacking， and the use of policy tools should be optimized in a coordinated manner； the distribution of stakeholders is relatively unbalanced， and synergies among stakeholders should be enhanced； the overall strength of policies is poor， and the top-level design of relevant policies should be improved.

Background and objective Pembrolizumab(PEM)has been shown to be effective in clinical trials for the treatment of advanced non-small cell lung cancer(NSCLC),but clinical trials were based on cohorts of patients selected on specific criteria,and whether the findings are consistent with real-world patients is debatable.The aim of this study is to evaluate the efficacy and safety of PEM in the treatment of advanced NSCLC based on real-world data.Methods A retro-spective collection of real-world data from patients with advanced NSCLC receiving PEM was conducted.Propensity score matching was used to eliminate inter-group differences and assess the efficacy and safety of PEM compared to chemotherapy.Results Among 450 matched patients,the incidence rates of any-grade adverse events were 79.87％in the PEM group and86.71％inthe chemotherapy group,while the incidence rates of grade＞3 adverse events were 4.03％and 7.31％,respectively.The objective response rates were 48.63％for PEM and 36.00％for chemotherapy(P=0.011).The median progression-free survival was 15.5 months for PEM and 8.8 months for chemotherapy(P＜0.001),and the median overall survival was not reached for PEM and 26.2 months for chemotherapy(P＜0.001).Conclusion PEM treatment for advanced NSCLC demonstrates favorable survival outcomes and acceptable safety in real-world clinical practice.

Objective:To explore the role of interleukin-18 (IL-18) in the pathogenesis of dermatomyositis (DM) associated with positive anti-melanoma differentiation-associated gene 5 antibodies(MDA5-DM).Methods:Twenty-eight cases of MDA5-DM in the department of rheumatology and immunology, the first hospital of Nanjing medical university and the first affiliated hospital od Wannan medical colledge from August 2018 to December 2011 were included in this study, comprising 15 cases with combined rapidly progressive interstitial pneumonia (RPILD) and 13 cases without RPILD (nonRPILD). Additionally, 28 cases of antisynthetase syndrome (ASS) and 28 healthy volunteers (HC) were included for comparison. Clinical, laboratory, and imaging data were collected for both the DM and ASS groups. Serum IL-18 levels were measured using ELISA. Independent t test, Mann-whitney U test, χ2 test and Fisher′s exact probability method were used for analysis. Results:Significant differences were observed in LDH, hydroxybutyrate dehydrogenase (HBDH), ESR, CRP, serum ferritin (SFE), and IL-18 levels between the MDA5-DM group, the ASS group and the HC group ( F=46.65, 43.19, 31.28, 23.94, 30.94, 49.44, all P<0.001). Additionally, lymphocyte counts and hemoglobin levels differed significantly among the three groups( F=35.26, P<0.001; F=18.59, P<0.001). MDA5-DM patients exhibited higher incidences of Gottron′s sign, helitrope rash, periungual erythema, skin ulcers, and RPILD compared to ASS patients ( χ2=20.96, P<0.001; χ2=5.85, P=0.016; χ2=13.69, P<0.001; χ2=9.16, P=0.002; χ2=4.79, P=0.029). However, the incidence of mechanic′s hand was lower in MDA5-DM patients ( χ2=3.90, P=0.048). The level of IL-18 significantly decreased in MDA5-DM after treatment[(104.28(71.96,151.10)pg/ml vs. 78.30(56.20, 94.80)pg/ml, =2.27, P=0.023)]. Similar reductions were observed in the ASS group[(72.30(61.39, 95.94)pg/ml vs. 45.30(29.00,84.10)pg/ml, Z=2.691, P=0.007]. The IL-18 level changes in the MDA5-DM combined with RPILD group were not statistically significant [99.49 (77.65, 130.87)pg/ml vs. 89.40(54.80, 120.20)pg/ml, Z=0.65, P=0.515]. In the MDA5-DM survival group, IL-18 levels decreased significantly after treatment [59.45(53.58, 81.63)pg/ml vs. 106.37(83.62, 152.07)pg/ml, Z=2.80, P=0.005], while the changes in the IL-18 levels of patients in the MDA5-DM death group were not statistically significant [99.49(56.70, 140.15)pg/ml vs. 94.80(71.40, 155.45)pg/ml, Z=1.75, P=0.080]. Conclusion:MDA5-DM patients are different from the ASS patients in clinical manifestations and indicators involved in laboratory tests. The expression level of IL-18 tends to increase during the active phase of MDA5-DM and ASS, and decrease with remission of the disease. MDA5-DM may play an important role in the pathogenesis, and persistent high level of IL-18 is responsible for RPILD and death of MDA5-DM. Sustained high level of IL-18 can be used as a potential biomarker for the estimating development of MDA5-DM into RPILD.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective:To compare the value of Caprini, Padua and Autar risk assessment models in the risk assessment of venous thromboembolism in hospitalized stroke patients.Methods:A retrospective case-control study were used to collect hospitalized stroke patients in the neurology department of Xiangya Hospital from January 1, 2018 to June 30, 2020. 75 patients with venous thromboembolism (VTE) were VTE group and 75 patients without VTE were control group. The risk of thrombosis was assessed by Caprini risk assessment model, Padua risk assessment model and Autar risk assessment model respectively. The predictive value of each model on the risk of VTE formation in stroke patients was analyzed by receiver operating characteristic (ROC) curve and area under the curve (AUC).Results:The areas under the curve of Caprini, Padua and Autar risk assessment models for predicting the risk of VTE formation in stroke patients were 0.768±0.039, 0.746±0.040 and 0.710±0.042 respectively. The sensitivity, specificity and accuracy were 81.3%, 61.3%, 71.3%(Caprini), 72.0%, 72.0%, 72.0%(Padua), 66.7%, 68.0% and 67.3%(Autar) respectively. There was no significant difference in the prediction value of the three models on the formation risk of stroke VTE (all P>0.05). The technique for order preference by similarity to ideal solution (TOPSIS) method was used to comprehensively evaluate the AUC, sensitivity, specificity and accuracy of the three risk assessment models. Padua risk assessment model was the best, followed by Caprini risk assessment model and Autar risk assessment model. Conclusions:The Caprini, Padua, and Autar risk assessment scales can well predict the risk of VTE in stroke patients. The Caprini scale has the highest sensitivity and the Padua scale has the highest specificity. There is no significant difference in the predictive value of the three scales. Comprehensive evaluation of predictive value: Padua risk assessment scale is the best.

The anterior cruciate ligament (ACL) injury is a common sports injury that has a significant impact on knee function and patients′ mobility. With the popularity of national fitness campaign in China, the incidence of ACL injury is increasing year by year. Currently, there still lacks clinical standards or guidelines on how to choose appropriate treatment methods, surgical plans and rehabilitation protocols for ACL injury. In order to timely reflect the new treatment concept of ACL injury, standardize its diagnosis and treatment and improve the curative effect, the Sports Medicine Society of Chinese Research Hospital Association and the Editorial Board of Chinese Journal of Trauma organized domestic orthopedic and sports medicine experts to formulate the "clinical evidence-based guideline for the diagnosis and treatment of anterior cruciate ligament injury (2022 version)" based on the level of evidence-based medicine and in compliance with the principle of scientificity, practicability and advancement. The present guideline includes 12 recommendations for the diagnosis, treatment and rehabilitation of ACL injury in order to provide guidance and assistance for the clinical diagnosis and treatment of ACL injury in China.

Objective:To evaluate the skin development and repair process of X-ray radiation damage in rat with non-invasive two-photon excitation fluorescence (TPEF) imaging technology in vivo. Methods:Totally 24 SD rats were randomly divided into four groups including X-ray irradiated group (25, 35 and 45 Gy) and non-irradiation control group. At different times after irradiation, the degree of skin injury was evaluated, and the pathological changes of nicotinamide adenine dinucleotide (phosphate) [NAD(P)H] and collagen fiber fluorescence signals in epidermal cells were detected in vivo by TPEF imaging technology. Results:At 10 d post-irradiation, the skin of irradiation groups showed erythema and desquamation. At 15-20 d post-irradiation, the skin of radiation groups developed progressive exudation, edema and ulcers with increasing radiation dose. On day 25, the skin began to repair in the 25 Gy group, however, the skin of other groups still had exudation and ulcers. On day 10, NAD(P)H fluorescence signal in epidermal cells of irradiation groups decreased and the fluorescence signal of collagen fibers in papillary layer and reticular layer of irradiation groups reduced, which were significantly lower than that of normal control group ( t=24.145, 28.303, 26.989, 6.654, 7.510, 7.997, P<0.05). On day 30, fluorescence signal of NAD(P)H and collagen fibers in epidermal cells and dermis began to repair, the cell from stratum granulosum, stratum spinosum, and stratum basale in the 25 Gy group showed fluorescence signal, the other groups did not show. The fluorescence signal of collagen fibers in the 25 Gy group were gradually increased in papillary layer and reticular layer, however, they were significantly lower than normal control group ( t=115.133, 17.431, P<0.05), the skin of 45 Gy group did not show fluorescence signal of collagen fibers. Conclusions:The damage and repair process of epidermal cells and dermal collagen fiber can be detected noninvasively by TPEF imaging technology after X-ray irradiation in vivo.
