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 research progress, research hotspot and development trend of tigecycline resistance based on the quantitative analysis and visualization function of CiteSpace. Methods The data were collected from 4,263 Chinese and English articles on tigecycline resistance in CNKI, Wanfang, VIP and Web of Science (WOS) databases from 2012 to 2022. CiteSpace 5.8.R3 software was used to analyze the cooperative network of authors, the cooperative network of countries and institutions, the total citation times of journals, and keywords included in the literature, to reveal the hotspots and trends of tigecycline resistance research. Results The number of articles published in English literature was higher than that in Chinese literature. China had the largest number of published documents, showing a significant international academic influence in this research field. Countries all over the world were concerned about the resistance of tigecycline, but Chinese literatures focused more on the clinical infection and prevention of tigecycline resistance, while English literatures placed special emphasis on the research about the drug resistance mechanism of tigecycline. Conclusion The research direction at home and abroad is basically the same, but the research focus has gradually shifted from the clinical treatment and monitoring of tigecycline to the molecular level of drug resistance mechanism.

Objective:To evaluate the value of 18F-FDG PET/CT for preoperative localization of epileptogenic foci in refractory epilepsy patients with negative MRI. Methods:Clinical data (550 lobes) of 55 epilepsy patients (38 males, 17 females, age (20.0±8.1) years) with negative MRI who underwent preoperative 18F-FDG PET/CT-MRI between January 2014 and June 2020 at the First Affiliated Hospital of Jinan University were retrospectively analyzed. The sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of 18F-FDG PET/CT, video electroencephalogram (VEEG), PET/CT+ VEEG and PET/CT-VEEG for localizing epileptogenic foci were calculated using stereoelectroencephalography (SEEG) and the outcomes of at least 1 year of postoperative follow-up as reference standards. χ2 test was used to compare the efficiencies of different examination modalities for unilobar, multilobar and all patients. Results:The correct lateralization rate of epileptogenic foci was 92.6%(25/27) using PET/CT. The sensitivity, specificity, accuracy, PPV and NPV of PET/CT for localization of epileptogenic foci were 65.1%(54/83), 77.9%(364/467), 76.0%(418/550), 34.4%(54/157) and 92.6%(364/393), respectively. The sensitivities of PET/CT-VEEG for localization of epileptogenic foci in all patients and patients with multilobar epilepsy were higher than those of VEEG alone (75.9%(63/83) vs 45.8%(38/83), 68.6%(35/51) vs 31.4%(16/51); χ2 values: 15.80, 14.16, both P<0.001). The specificities of PET/CT+ VEEG for localization of epileptogenic foci in all patients and patients with unilobar epilepsy were higher than those of VEEG alone (97.6%(456/467) vs 94.6%(442/467), 97.9%(282/288) vs 94.1%(271/288); χ2 values: 5.66, 5.48; P values: 0.017, 0.019). The sensitivity of PET/CT-VEEG (PET/CT and VEEG concordance) for localization of epileptogenic foci was higher than that of PET/CT+ VEEG (PET/CT and VEEG discordance) (8/9 vs 28.4%(21/74); χ2=10.40, P=0.001), and its specificity and accuracy were higher than those of PET/CT-VEEG (PET/CT and VEEG discordance) (93.4%(57/61) vs 71.7%(291/406), 92.9%(65/70) vs 72.1%(346/480); χ2 values: 13.23, 13.96; both P<0.001). Conclusions:18F-FDG PET/CT can localize and lateralize epileptogenic foci in patients with negative MRI. The combination of 18F-FDG PET/CT and VEEG improves the sensitivity, specificity, and accuracy for epileptogenic foci detection. 18F-FDG PET/CT is more accurate in detecting epileptogenic foci when it is concordant with VEEG.

Objective:To explore the reproductive concerns of male thyroid cancer patients of childbearing age and analyze their influencing factors.Methods:From May 2022 to August 2023, convenience sampling was used to select 298 male thyroid cancer patients of childbearing age who visited two ClassⅢ Grade A hospitals in Wuhan as research subjects. General Information Questionnaire, Reproductive Concerns after Cancer Scale-Male, Distress Disclosure Index, and 14-Item Resilience Scale were used for the survey. Single factor analysis and multiple linear hierarchical regression were used to analyze the influencing factors of reproductive concerns.Results:A total of 275 male thyroid cancer patients of childbearing age were included. The total scores of reproductive concerns, self-disclosure, and psychological resilience were (47.66±11.44), (37.22±5.80), and (62.45±8.73), respectively. The score of reproductive concerns was negatively correlated with the scores of self-disclosure and psychological resilience, and the difference was statistically significant ( r=-0.636, -0.656; P<0.01). Hierarchical regression analysis showed that educational level, monthly family income, number of children, fertility intention, 131I treatment, self-disclosure, and psychological resilience were the influencing factors of reproductive concerns in male thyroid cancer patients of childbearing age ( P<0.05). After controlling for demographic and sociological data, self-disclosure and psychological resilience explained 8.6% of reproductive concerns among male thyroid cancer patients of childbearing age. Conclusions:Male thyroid cancer patients of childbearing age have a moderate to high level of reproductive concerns. Medical and nursing staff should develop systematic and effective intervention strategies based on influencing factors to reduce reproductive concerns among male thyroid cancer patients of childbearing age.

Objective To investigate the clinical value of left ventricular global longitudinal strain (LVGLS) combined with the global register of acute coronary events (GRACE) score in predicting coronary microcirculation disorder (CMD) in patients with acute myocardial infarction (AMI) after emergency percutaneous coronary intervention (PCI). Methods A total of 90 patients with AMI were selected as the study objects (10 cases were lost in follow-up, 4 cases were screened for poor image quality), and 76 cases were finally included. Left ventricular myocardial contrast echocardiography (MCE) was performed in patients at 48 h after surgery. Patients were divided into non-CMD group (n=53) and CMD group (n=23) according to coronary microcirculation perfusion. Clinical data and echocardiographic data of the two groups were analyzed and compared. Multivariate Logistic regression analysis was used to screen the influencing factors of CMD occurrence, and receiver operating characteristic (ROC) curve was drawn to analyze its clinical predictive value. Results Of the 76 patients, 23(30.3%) cases had CMD. LVGLS and GRACE scores in the CMD group were higher than those in the non-CMD group, and the differences were statistically significant (P < 0.05). Multivariate Logistic regression analysis showed that LVGLS and GRACE score were independent predictors of CMD in AMI patients after emergency PCI. The area under the curve of CMD predicted by LVGLS was 0.858 (95%CI, 0.769 to 0.948). LVGLS combined with GRACE predicted that the area under the curve for CMD was 0.891 (95%CI, 0.815 to 0.967). Conclusion LVGLS is an independent predictor for early assessment of CMD occurrence in AMI patients after emergency PCI, and its combination with GRACE score can improve the accuracy of predicting CMD occurrence.

Objective:To investigate the effect of histone deacetylase inhibitor trichostatin A(TSA) on the lipopolysaccharide(LPS)-induced injury and apoptosis of human microvascular endothelial cell(HMEC).Methods:HMECs were used as research cells to establish LPS-induced septic cell model, which were divided into three groups according to different treatments: control group (150 μL of phosphate buffer), LPS group (150 μL of 5 μg/mL LPS), LPS+ TSA group (150 μL of 5 μg/mL LPS and 500 μg/L TSA). After cells of each group were cultured for 24 h and 48 h, the concentration of lactate dehydrogenase(LDH)in the culture supernatant was detected by enzyme-linked immunosorbent assay and the apoptosis rate of HMECs was detected by Annexin V-FTTC/PI staining, then comparison between different groups were made.Results:Compared with the control group, LDH concentration in LPS group increased significantly at 24 h[(4.67±1.27) ng/L vs. (11.57±0.83) ng/L ] and 48 h[(7.93±0.80) ng/L vs. (12.72±0.89) ng/L ]; Compared with LPS group, LDH concentration in LPS + TSA group decreased significantly at 24 h[(6.01±0.29) ng/L ] and 48 h[(5.96±0.27) ng/L ], and the differences were statistically significant ( P<0.05). Compared with the control group, the apoptosis rates of HMEC cells in LPS group were significantly higher at 24 h[(0.92±0.89)% vs. (1.66±0.09)% ] and 48 h[(1.09±0.14)% vs. (5.01±0.16)%]; Compared with LPS group, the apoptosis rate of HMEC cells in LPS + TSA group significantly decreased at 24 h[(1.36±0.01)% ] and 48 h[(4.19±0.23)% ], the differences were statistically significant ( P<0.05). Conclusion:TSA has the protective effect of reducing cell injury and apoptosis in sepsis.

Oligoasthenospermia is the primary cause of infertility. However, there are still enormous challenges in the screening of critical candidates and targets of oligoasthenospermia owing to its complex mechanism. In this study, stem cell factor (SCF), c-kit, and transient receptor potential vanilloid 1 (TRPV1) biosensors were successfully established and applied to studying apoptosis and autophagy mechanisms. Interestingly, the detection limit reached 2.787 × 10^-15 g/L, and the quantitative limit reached 1.0 × 10^-13 g/L. Furthermore, biosensors were used to investigate the interplay between autophagy and apoptosis. Schisandrin A is an excellent candidate to form a system with c-kit similar to SCF/c-kit with a detection constant (K_D) of 5.701 × 10^-11 mol/L, whereas it had no affinity for SCF. In addition, it also inhibited autophagy in oligoasthenospermia through antagonizing TRPV1 with a K_D of up to 4.181 × 10^-10 mol/L. In addition, in vivo and in vitro experiments were highly consistent with the biosensor. In summary, high-potency schisandrin A and two potential targets were identified, through which schisandrin A could reverse the apoptosis caused by excessive autophagy during oligoasthenospermia. Our study provides promising insights into the discovery of effective compounds and potential targets via a well-established in vitro-in vivo strategy.

Objective:To investigate the iodine nutritional status of adults and pregnant women in Jianshui County and Zhenxiong County, Yunnan Province.Methods:From May to August 2021, one urban area and one rural area in Jianshui County and Zhenxiong County, Yunnan Province were selected as investigation sites. At least 100 adults (half male and half female) and 100 pregnant women were selected as survey subjects in each investigation site. Random urine samples were collected from all survey subjects once to detect urine iodine, creatinine and sodium contents. Venous blood samples of all pregnant women were collected to detect the serum iodine content, and the 95% medical reference range of serum iodine was established using the percentile method.Results:The medians urinary iodine, creatinine and sodium of adults in Jianshui County and Zhenxiong County were 184.7 μg/L ( n = 432), 12 355.0 μmol/L ( n = 431) and 156.5 mmol/L ( n = 420), respectively. The median urinary iodine of adults in Jianshui County was higher than that in Zhenxiong County (197.3 vs 170.2 μg/L), the difference was statistically significant ( Z = - 2.90, P = 0.003). The median serum iodine of pregnant women in Jianshui County and Zhenxiong County was 92.1 μg/L ( n = 412), with a 95% medical reference value ranged from 45.3 to 183.5 μg/L; the medians urinary iodine, creatinine and sodium of pregnant women were 138.6 μg/L ( n = 413), 12 173.0 μmol/L ( n = 408) and 152.2 mmol/L ( n = 409), respectively. The urinary iodine (154.1 vs 115.8 μg/L), urinary creatinine (13 216.0 vs 11 376.0 μmol/L) and urinary sodium (161.8 vs 141.8 mmol/L) of pregnant women in Jianshui County were higher than those in Zhenxiong County, with statistical differences ( Z = - 5.12, - 2.29, - 4.30, P < 0.05). Conclusion:Adults in Jianshui County and Zhenxiong County are at an appropriate level of iodine, but pregnant women in Zhenxiong County are at an iodine deficiency level.

After treatment, there was no significant difference in the clearance rate of escherichia coli, klebsiella pneumoniae, bacteroides fragile and staphylococcus aureus in the observation group ( P>0.05), but there was significant difference in the overall bacterial clearance rate compared with the control group ( P<0.05). The incidence of adverse reactions in the observation group was significantly lower than that in the control group ( P<0.05). Conclusions:The use of morpholinidazole in patients with perianal abscess is effective and safe.

Multidrug resistance (MDR) mediated by ATP binding cassette subfamily B member 1 (ABCB1) is significantly hindering effective cancer chemotherapy. However, currently, no ABCB1-inhibitory drugs have been approved to treat MDR cancer clinically, mainly due to the inhibitor specificity, toxicity, and drug interactions. Here, we reported that three polyoxypregnanes (POPs) as the most abundant constituents of
