Implementation Science is an interdisciplinary field dedicated to systematically studying how to effectively translate evidence-based research findings into practical application and implementation. In the health-related context, it focuses on enhancing the efficiency and quality of healthcare services, thereby facilitating the transition from scientific evidence to real-world practice. This article elaborates on Theories, Models, and Frameworks (TMF) within health-related Implementation Science, clarifying their basic concepts and classifications, and discussing their roles in guiding implementation processes. Furthermore, it reviews and prospects current research from three aspects: the constituent elements of TMF, their practical applications, and future directions. Five representative frameworks are emphasized, including the Consolidated Framework for Implementation Research (CFIR), the Practical Robust Implementation and Sustainability Model (PRISM), the Exploration, Preparation, Implementation, Sustainment (EPIS)framework, the Behavior Change Wheel (BCW), and the Normalization Process Theory (NPT). Additionally, resources such as the Dissemination & Implementation Models Webtool and the T-CaST tool are introduced to assist researchers in selecting appropriate TMFs based on project-specific needs.

Objective:To explore the mechanism of Huangqi Jiedu Decoction (HQJD) in the treatment of breast cancer with the syndrome of Zheng deficiency and toxic incandescence by network pharmacology and molecular docking technology.Methods:The main active ingredients and targets of HQJD were screened through the traditional Chinese medicine (TCM) systematic pharmacology database and analysis platform. The relevant targets of breast cancer with the syndrome of Zheng-deficiency, toxic-incandescence were obtained using OMIM, GeneGards and Drugbank databases, and the relevant targets of HQJD for the treatment of breast cancer with the syndrome of Zheng-deficiency and toxic incandescence were obtained by intersection; The Cytoscape 3.9.1 software was used to build the protein protein interaction (PPI) network and the " drug active component target disease" network on the basis of String 11.0 database, and the core active components and core targets of HQJD in treating breast cancer with the syndrome of Zheng-deficiency and toxic-incandescence were inferred according to the topological parameters. gene ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis were performed on core targets using R language; and molecular docking verification on the main active ingredients and core targets were conducted.Results:230 effective targets of active ingredients of HQJD were screened, and 15 467 active ingredients of breast cancer with syndrome of Zheng-deficiency/toxic-incandescence were obtained; 217 intersection targets; GO function enrichment analysis showed that the treatment of HQJD for breast cancer with the syndrome of Zheng-deficiency and toxic-incandescence mainly involved oxidative stress and cytochemical stress; The enrichment analysis of KEGG pathway showed that HQJD treatment of breast cancer with the syndrome of Zheng-deficiency and toxic-incandescence was mainly related to phosphatidylinositol 3-protein kinase B (PI3K-Akt), interleukin-17 (IL-17) and other signal pathways. The molecular docking results showed that the main active ingredients such as β-sitosterol, stigmasterol, luteolin had good binding ability with core targets.Conclusions:HQJD has the characteristics of multi-component, multi target and multi pathway in the treatment of breast cancer with syndrome of Zheng-deficiency and toxic-incandescence, and its main mechanism may be related to PI3K-Akt, IL-17, P53 and other signal pathways.

ObjectiveBased on non-targeted metabolomics， to analyze the regulation of endogenous differential metabolites in serum of type 2 diabetes mellitus（T2DM） rats by Fuling Yunhua granules， and to clarify the metabolic pathways through which this granules exerted its effect on improving T2DM. MethodSeventy SD rats， half male and half female， were randomly divided into the control group， model group， and high， medium， low dose groups of Fuling Yunhua granules（20.70， 10.35， 5.18 g·kg^-1 in raw drug amount） and the positive drug group（pioglitazone hydrochloride tablets， 8.1 mg·kg^-1）. Except for the control group， other groups were fed with high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin（STZ） to establish a T2DM rat model. After successful modeling， the treatment groups were administered the corresponding drugs by gavage， and the control group and model group were treated with an equal volume of saline by gavage， once/d， for 28 d. Fasting blood glucose（FBG） and glycosylated hemoglobin A1c（GHbA1c） levels were measured in all groups of rats during the administration period， and hematoxylin-eosin（HE） staining was used to observe the pathomorphological changes in the pancreatic tissues of rats at the end of the administration period. The endogenous metabolite levels in rat serum were detected by ultra-performance liquid chromatography-linear ion trap-electrostatic field orbitrap high-resolution mass spectrometry（UPLC-LTQ-Orbitrap MS）， and the data were processed using principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA）. Differential metabolites were identified by the Human Metabolome Database（HMDB） and the Kyoto Encyclopedia of Genes and Genomes（KEGG）， and screened for differential metabolites with variable importance in the projection（VIP） value>1， P<0.05， and fold change（FC）<0.6 or FC>1. And the metabolic pathway enrichment analysis of the screened differential metabolites was performed by MetaboAnalyst 5.0， then the screened differential metabolites were diagnosed and evaluated by the receiver operating characteristic（ROC） curves. ResultCompared with the control group， the FBG level of rats in the model group increased significantly（P<0.01）， the GHbA1c content tended to increase， but the difference was not statistically significant， and the pancreatic tissue of rats was obviously damaged， the number of pancreatic islets decreased， and the pancreatic β-cells were obviously reduced， atrophied and enlarged. Compared with the model group， the FBG levels of rats in the high dose group of Fuling Yunhua granules and the positive drug group were significantly reduced after 2 weeks of administration（P<0.05， P<0.01）， the GHbA1c content of rats in the high dose group of Fuling Yunhua granules was significantly reduced（P<0.05）， and the pancreatic tissue lesions of rats in the different dose groups of Fuling Yunhua granules were reduced. The results of non-targeted metabolomics showed that 46 differential metabolites were significantly changed in the model group compared with the blank group. Pathway enrichment analysis found that T2DM mainly affected biological processes including biosynthesis of primary bile acid， D-amino acid metabolism， steroid hormone biosynthesis， and glycerophospholipid metabolism in rats. Compared with the model group， the levels of 8 differential metabolites in the high dose group of Fuling Yunhua granules were significantly adjusted， and the pathway enrichment analysis found that D-amino acid metabolism， retinol metabolism， glycine， serine and threonine metabolism， tryptophan metabolism and other metabolic pathways were mainly involved. ROC curves further analysis revealed that the four characteristic differential markers of 11-cis-retinol， D-piperidinic acid， D-serine， and p-cresol sulfate had high diagnostic value for the treatment of T2DM with Fuling Yunhua granules. ConclusionFuling Yunhua granules can improve the symptoms of T2DM rats by regulating the amino acid metabolic and retinol metabolic pathways through the modulation of endogenous differential metabolites.

Objective:To explore the strategy of prostate biopsy in patients with prostate specific antigen(PSA)gray zone based on prostate imaging reporting and data system (PI-RADS).Methods:The clinical data of 427 patients who underwent transperineal prostate biopsy in the First Affiliated Hospital of Nanjing Medical University from January 2020 to December 2022 were retrospectively analyzed. The median age was 66 (61, 72) years old. The median PSA was 6.62 (5.46, 8.19) ng/ml. The median PSA density (PSAD) was 0.15 (0.11, 0.21) ng/ml 2. The median prostate volume (PV) was 43.68 (31.12, 56.82) ml. PSA velocity (PSAV) data were available in 65 patients with negative MRI examination(PI-RADS <3), and the median PSAV was 1.40 (0.69, 2.89) ng/(ml· year). Among the patients with positive MRI(PI-RADS≥3), there were 174 patients with only 1 lesion and 83 patients with ≥2 lesions. A total of 170 patients with negative MRI underwent systematic biopsy, and 257 patients with positive MRI underwent systematic combined targeted biopsy. The PI-RADS score, regions of interest(ROI), PSAD, f/tPSA and PSAV were analyzed to explore the biopsy strategy for patients with PSA gray area based on bpMRI imaging. Results:Of the 427 patients included in the study, 194 were positive and 233 were negative. Among the patients with positive biopsy pathology, 140 cases were clinically significant prostate cancer (CsPCa). Among the MRI-negative patients, there were 33 cases with PSAV ≥1.4 ng/(ml·year), and 10 cases of prostate cancer and 6 cases of CsPCa were detected by systematic biopsy.In 32 cases with PSAV <1.4 ng/(ml·year), 3 cases of prostate cancer and 0 case of CsPCa were detected by systematic biopsy. The sensitivity of systematic biopsy for the diagnosis of prostate cancer and CsPCa in patients with PSAV≥1.4 ng/(ml·year) were 76.9% (10/13) and 100.0% (6/6) respectively, the specificity were 55.8% (29/52) and 54.2% (32/59) respectively, the negative predictive value were 90.6% (29/32) and 100.0% (32/32) respectively, and the positive predictive value were 30.3% (10/33) and 18.2% (6/33) respectively. In MRI-positive patients with PI-RADS 3, the prostate cancer detection rates of targeted biopsy combined with systematic biopsy, systematic biopsy and targeted biopsy were 41.7% (45/108), 32.4% (35/108) and 35.2% (38/108), respectively ( P=0.349). The detection rates of CsPCa were 27.8% (30/108), 21.3% (23/108) and 25.0% (27/108), respectively ( P=0.541). In patients with PI-RADS 4-5 and PSAD > 0.15 ng/ml 2, the detection rates of CsPCa in targeted biopsy combined with systematic biopsy, systematic biopsy and targeted biopsy were 67.8% (61/90), 58.9% (53/90) and 67.8% (61/90), respectively ( P=0.354). Conclusions:For MRI-negative patients, all CsPCa could be detected by perineal systematic biopsy when PSAV ≥1.4 ng/(ml·year), and active observation could be performed when PSAV <1.4 ng/(ml·year). For MRI-positive patients, targeted combined systemic biopsy was required when PI-RADS score was 3, and targeted biopsy only could be performed when PI-RADS score ≥4 and PSAD >0.15 ng/ml 2, otherwise targeted combined systemic biopsy was required.

OBJECTIVE To evaluate the mode of pharmacists’ participation in multi-disciplinary diagnosis and treatment （MDT）， as well as the effects of pharmacists’ participation. METHODS Retrieved from Cochrane Library， PubMed， Embase， CNKI， CBM and Wanfang database， experimental studies and observational studies on the effects of MDT with pharmacists on clinical outcomes of patients were collected. After data extraction and quality evaluation， the results of included studies were analyzed descriptively. RESULTS A total of 10 studies were included， among which 3 were randomized controlled trials （RCT）， 2 were non-RCT， 4 were cohort and 1 was case-control study； there were 2 422 patients in total. In terms of effectiveness， tumor progression-free survival， glycosylated hemoglobin， re-admission rate and length of stay and other indexes were all improved significantly after pharmacists participated in MDT. In terms of safety， the incidence of major bleeding events was significantly decreased after pharmacists participated in MDT. In terms of economy， hospitalization costs and total outpatient expenses were improved significantly after pharmacists participated in MDT， but medical cost was not improved significantly. In terms of humanistic outcomes， there was controversy over the conclusion of patient compliance after pharmacists participated in MDT. CONCLUSIONS Pharmacists， based on their own pharmaceutical care skills and methods， actively participate in MDT throughout the process， improving the clinical outcomes of patients and enhancing the safety of medication. There are still controversies regarding economic and humanistic outcomes.

Objective:To explore the promoting effects of slit guidance ligand 2 (Slit2) on the repair of corneal epithelium and nerve damage in diabetic mice and possible molecular mechanism.Methods:Sixty SPF C57BL/6 mice aged 5-6 weeks were divided into normal control group, diabetes model group and Slit2 injection group according to the random number table method, 20 for each group.Diabectic model was prepared by intraperitoneal injection of streptozotocin in the diabetes model group and Slit2 injection group.A mouse corneal epithelial injury repair model was established using electric epithelial scraper, and Slit2 recombinant protein was subconjunctivally injected immediately following modeling in the Slit2 injection group.The equal volume of phosphate buffer saline (PBS) was used in a same way in the diabetes model group.No intervention was performed in the normal control group.Corneal epithelial healing were examined at 24, 48 and 72 hours after corneal epithelial defect by corneal fluorescin staining.Real-time fluorescent quantitative PCR was used to detect the expression of Slit2 and its related receptors in the corneal epithelium of normal and diabetic model mice.Fluorescence staining of corneal wholemount with β-tubulin Ⅲ was used to observe the changes in corneal nerve morphology.Immunofluorescence staining was performed to detect the expression and distribution of Slit2 in mouse corneal epithelium in normal control group and diabetes model group, as well as the expression and distribution of Slit2, epidermal growth factor receptor (EGFR), extracellular-signal-regulated kinase (ERK), threonine protein kinase (AKT), β-catenin and Ki67 in the healing corneal epithelium of mice after corneal epithelium damage in different groups.The mouse corneal epithelial stem/progenitor cell line (TKE2) was divided into normal control group, high-glucose group and Slit2 treatment group.Western blot was performed to detect the expression of p-EGFR/EGFR and p-AKT/AKT in the TKE2 of the three groups.The expression of p-EGFR/EGFR and p-AKT/AKT in high glucose-cultured TKE2 with 0.01, 0.1 and 0.5 μg/ml Slit2 treatment for 10 minutes, and before and 10, 20, 30, 60, 120 minutes after 0.5 μg/ml Slit2 treatment was detected by Western blot.The effects of Slit2 on the axon regeneration of mouse trigeminal ganglion cells (TGs) were observed by immunofluorescence staining.The use and care of animals complied with the ARVO statement.This study protocol was approved by an Ethics Committee of Qingdao Eye Hospital of Shandong First Medical University (No.[2020]57).Results:At 48 and 72 hours after corneal epithelial scraping, the speed of corneal epithelial repair was significantly slowed down in diabetes model group in comparison with the normal control group and Slit2 injection group.The relative expression levels of Slit2 and its receptors Robo1, Robo2 and Robo4 mRNA in the normal corneal epithelium in the diabetes model group were significantly higher than those of the normal control group (all at P<0.05). The fluorescence intensity of Slit2 in normal corneal epithelium in diabetes model group was similar to the normal control group, and the fluorescence intensity of Slit2 in damaged corneal epithelium in diabetic mice was significantly weaker than that in normal control group.Corneal nerve plexus was denser at 7 days after corneal epithelial injury and the nerve fibers were increased with more branches in Slit2 injection group compared with diabetic group.The fluorescence intensity of p-EGFR, p-ERK, β-catenin and Ki67 in damaged corneal epithelium in normal control group and Slit2 injection group was stronger than that of the diabetes model group.The relative expression levels of p-EGFR/EGFR, p-AKT/AKT, and β-catenin in TKE2 in high-glucose group were significantly lower than those in normal control group and Slit2 treatment group (all at P<0.05). The relative expression levels of p-EGFR/EGFR and p-AKT/AKT in high glucose-cultured TKE2 after Slit2 treatment were significantly increased in comparison with before Slit2 treatment (both at P<0.05), and the relative expression levels of p-EGFR/EGFR and p-AKT/AKT in TKE2 were elevated as the increase of Slit2 concentration.The activation effect of 0.5 μg/ml Slit2 on EGFR and AKT pathways was most obvious.The synapse length of TGs cultured by high glucose was (40.52±5.44) μm, which was significantly shortened than (72.14±9.48) μm in normal control group and (73.04±4.66) μm in Slit2 injection group (both at P<0.05). Conclusions:Slit2 can protect the corneal epithelium by activating EGFR signaling pathway and play a protective role to neurons by increasing the density of corneal subepithelial plexus and promoting the growth of TGs axons in diabetic mice.

Objective:To explore the efficacy of single-plane bi-parameter magnetic resonance imaging (bpMRI) in the diagnosis of prostate cancer.Methods:The clinical data of 343 patients who underwent transperineal template prostate magnetic resonance-transrectal ultrasound (MRI-TRUS) cognitive fusion biopsy at the First Affiliated Hospital of Nanjing Medical University from January 2020 to July 2021 were retrospectively analyzed, with median age of [65.0(59.0, 72.0)] years, median body mass index (BMI) of [24.1(22.2, 25.6)]kg/m 2, median prostate volume (PV) of [41.7(29.1, 53.3)]ml, median PSA[6.9 (5.5, 8.4) ng/ml], median PSAD of[0.17(0.12, 0.22) ng/ml 2], and abnormal rate of digital rectal examination (DRE) [6.4%(22/343)]. All patients underwent initial biopsy and bi-parameter magnetic resonance imaging (bpMRI) examination before biopsy, and the images were interpreted using prostate image reporting and data system version 2.1 (PI-RADS v2.1). The detection rates of prostate cancer and clinically significant prostate cancer (csPCa) were compared between single-plane bpMRI and bpMRI. When PI-RADS≥3 score, MRI results were positive; when PI-RADS ≤2 score, MRI results were negative. Results:In the single-plane bpMRI group, 121 MRI results were negative and 222 were positive. Positive patients included 95 with PI-RADS 3 score, 94 with PI-RADS 4 score, and 33 with PI-RADS 5 score. In bpMRI group, 141 MRI results were negative and 202 were positive. Among the positive patients, 67 patients with PI-RADS 3 score, 102 patients with PI-RADS 4 score, and 33 patients with PI-RADS 5 score. The detection rates of single-plane bpMRI and bpMRI for prostate cancer were 22.3% (27/121) and 15.6% (22/141) in MRI negative cases[22.3% (27/121) and 15.6% (22/141), P=0.17], and PI-RADS scores with 3 points [35.8% (34/95) vs. 44.8% (30/67), P=0.25], 4 points [89.4% (84/94)vs. 90.2% (92/102), P=0.85] and 5 points [90.9% (30/33) vs. 93.9% (31/33), P=1.00] showed no significant difference in stratification. The detection rate of csPCa in the single-plane bpMRI group and bpMRI group was significantly different in the MRI negative cases [7.4% (9/121) and 2.1% (3/141), P=0.04]. PI-RADS scores with 3 points [22.1% (21/95) vs. 29.9% (20/67), P=0.27], 4 points [80.9% (76/94) vs. 79.4% (81/102), P=0.80] and 5 points [84.9% (28/33) vs. 90.9% (30/33), P=0.71] showed no significant difference in stratification. Conclusions:For those suspected of prostate cancer patients with PSA 4-10 ng/ml and PI-RADS score ≥3, single-plane bpMRI or bpMRI examination has the same efficacy in term of the detection rate of prostate cancer and csPCa.

Objective:To explore the prevalence and influencing factors of allergic conjunctivitis in Baotou area at different times.Methods:A cross-sectional study was conducted in January 2021, 111 patients with allergic conjunctivitis who were admitted to the Department of Ophthalmology, the Second Affiliated Hospital of Baotou Medical College, Inner Mongolia University of Science and Technology in 2020 were selected as the research subjects. The basic information, allergic conditions, living habits and other information of the patients were obtained by self-made questionnaire. The pollen concentration and allergy related indicators(allergic duration and frequency, eye itching score, eye burn score, eye foreign body sensation score, tears score and the total scores) of 2019 and 2020 were analyzed by paired sample t-test. The pollen concentration of 2019 and 2020 were analyzed by Wilcoxon signed rank test. The allergy related indicators of different genders were analyzed by independent sample t-test. The allergy related indicators of different ages were analyzed by one-way analysis of variance. The relationship between the length of wearing masks and the allergy related indicators were analyzed by Spearman correlation analysis. Results:Among the 111 patients with allergic conjunctivitis, 54 were males and 57 were females, ranging in age from 8 to 69 years old, with a median age of 35 years old and an average age of (36.77±13.18) years old. The average pollen concentration in Baotou in 2019 was (125.35±222.64) grains/1 000 square millimeter, and the average pollen concentration in Baotou in 2020 was (107.38±137.29) grains/1 000 square millimeter. There was no significant difference in pollen concentration between the two years( Z=-0.178, P=0.859). The severity of allergic indicators in all patients in 2020 is significantly lower than in 2019( t values were 4.701,3.587,2.582,3.661,4.444,2.784,2.555,3.886,respectively, with P<0.05). The severity of allergic indicators in male patients is lower than that of female patients ( t values were -1.558, -1.257, -3.41, -3.085, -2.335, -2.897, -2.652, -4.124, respectively). The prevalence of allergic conjunctivitis dose not vary significant with age ( P values were 0.504, 0.095, 0.499, 0.265, 0.284, 0.655, 0.421, 0.976, respectively). In 2020, the average time that patients wear masks is (6.55±3.28) h/d, and there is a correlation with the difference in allergy duration ( r=0.191, P=0.045). Conclusion:The severity of allergic conjunctivitis in Baotou in 2020 was significantly improved compared with that in 2019, which may be related to masks wearing.
