Implementation strategies are targeted interventions aimed at promoting the adoption, implementation, and sustainment of research findings or evidence-based practices in routine healthcare. If implementation strategies can precisely match implementation barriers and facilitators, the likelihood of successful implementation will increase. The CFIR-ERIC matching tool, which can match corresponding ERIC implementation strategies based on CFIR barriers, is a convenient and direct tool for developing implementation strategies. This paper provides a detailed overview of the origins and development of the CFIR-ERIC matching tool, outlines its contents and usage, and illustrates how to apply the tool to develop implementation strategies by using a brief smoking cessation intervention project as an example. The paper also discusses the advantages and limitations of using this tool for developing implementation strategies, with the aim of providing methodological reference for other researchers.

Objective To investigate the potential mechanism of Jianpi Shenshi Formula for the treatment of hyperuricemia(HUA)by using network pharmacology and molecular docking techniques.Methods The active ingredients of Jianpi Shenshi Formula were searched and screened by combining TCMSP,BATMAN,and TCM-ID database with literature,and then SwissTargetPrediction was used to obtain the corresponding targets of the ingredients.Cytoscape 3.8.0 was used to construct a"drug-ingredients"network to analyze and obtain the main active ingredients of Jianpi Shenshi Formula.The GeneCards,OMIM,and disgenet databases were used to obtain the relevant targets of hyperuricemia.The intersection targets of Jianpi Shenshi Formula and hyperuricemia were imported into the STRING database for protein-protein interaction(PPI)network analysis,and hub targets for network were screened by CytoHubba plug-in.Meanwhile,the GO function and KEGG pathway enrichment analysis of the intersection targets were carried out using R4.2.2 software.Molecular docking of hub targets and key ingredients was performed using CB-DOCK 2.Results A total of 90 active ingredients of Jianpi Shenshi Formula were screened,among which quercetin,kaempferol,luteolin,stigmasterol,and ethyl linoleate were the main active ingredients,and 837 targets corresponding to the ingredients were obtained,with a total of 64 intersecting targets.CASP3,IL1B,IL6,PPARG,SIRT1,MAPK3,TNF,STAT3,TGFβ1,PTGS2,and XDH were the hub targets.The potential targets of action are mainly enriched in signaling pathways such as inflammation,metabolism,environment,cellular processes,biological systems,and hyperuricemia-related pathways.Conclusion Jianpi Shenshi Formula may exert effects on inhibition of uric acid production,and/or enhancement of uric acid excretion,anti-inflammation,and amelioration of related complications through the modulation of hyperuricemia-related signaling pathways(including neoplastic,infectious,metabolic,and cardiovascular diseases),as well as metabolic,immune,inflammatory,and other biological pathways by a variety of active ingredients such as quercetin,kaempferol,luteolin,stigmasterol,and ethyl linoleate.

ObjectiveTo analyze the epidemic characteristics and trend of mosquito vectors related to Japanese encephalitis （JE） in Mengla County， and to provide scientific evidence for JE prevention and control. MethodsThe JE related mosquito vector monitoring data in Mengla County from 2016 to 2020 were collected and subjected to further statistical analysis. ResultsA total of 1 689 mosquitoes were captured at the JE mosquito vector monitoring sites in Mengla County， 36.3% of which were captured in 2020 and 13.3% in 2017. The density of Culex tritaeniorhynchus was the highest （3.04 per lamp per day）， and that of Anopheles sinensis was the lowest （1.03 per lamp per day）. The distribution of mosquito species showed significant difference in the same year. The mosquito density in pig house was 12.93 per lamp∙day， and that in human house was 4.67 per lamp∙day. The mosquito density of different mosquito species in pig house was higher than that in human house. There was no significant difference in the site distribution of Anopheles sinensis， but there were significant differences in the site distribution of Culex tritaeniorhynchus， Culex pipiens quinquefasciatus and other mosquito species. The mosquito density peaked in May （12.78 per lamp per day） and July （10.28 per lamp per day）. The temporal distribution showed that the vector density decreased gradually from May to October， however， the species population structure also varied significantly， and the trends of each mosquito species also varied greatly. In Mengla， Culex tritaeniorhynchus peaked in May. ConclusionThe JE epidemic situation in Mengla County is still severe. It is recommended to strengthen prevention and control in the peak season of mosquito activities， such as actively carrying out patriotic health campaigns， and effective public education. At the same time， we should also strengthen the JE vaccination for school-age children and the training of medical personnel.

MethodsWe collected the case information of dengue fever in Mengla County reported by the infectious disease reporting information system of China Center for Disease Control and prevention from January 1 to December 31， 2019 and the case field investigation records. The case data were analyzed by descriptive epidemiological method. ResultsIn 2019， Mengla County reported 369 cases of dengue fever， all of which were unclassified， including 354 clinically diagnosed cases， 15 confirmed cases， 6 severe cases， and there was no deaths. The annual incidence rate was 120.98/10⁵. Mengla Town had the most cases （145 cases， 39.30%） followed by 63 cases （17.07%） in Mengpeng Town. The reported cases were mainly local cases （65.85%）. The ratio of male to female was 1.25∶1. The age distribution was mainly in the group of 21‒60 years old （82.38%）. Farmers （112 cases， 30.35%） and business service providers （85 cases， 23.04%） were the majority. The annual cases were distributed from May to November， of which the most were reported in September， and the number of cases reported from July to October accounts for 93.22% of all cases. ConclusionMengla County is still a high incidence area of dengue fever in Yunnan Province， and the vector Aedes is widespread. It is suggested to strengthen mosquito prevention and control in the epidemic season， actively carry out patriotic health campaign， carry out special rectification of the environment in rural areas， and conduct effective public education.

Objective:To compare the clinical efficacy, adverse reactions and prognosis of different radiotherapy schemes in the treatment of advanced esophageal squamous cell carcinoma.Methods:The clinical data of 60 patients with stage ⅣB esophageal squamous cell carcinoma who received radiotherapy in Rugao People′s Hospital of Jiangsu Province from January 2015 to January 2020 were retrospectively analyzed. According to the radiation doses, the patients were divided into standard dose group (total radiation dose <50.4 Gy) and high dose group (total radiation dose ≥50.4 Gy), with 30 patients in each group. The scores of dysphagia before and after treatment were analyzed by Wilcoxon signed-rank test. The radiotherapy effective rate, remission rate of dysphagia and incidence of adverse reactions were analyzed by χ2 test. Survival analysis was carried out by Kaplan-Meier and log-rank test was used to compare the prognosis of the two groups. Results:There were no significant differences in dysphagia scores between standard dose group and high dose group before and after radiotherapy ( Z=1.232, P=0.876; Z=1.506, P=0.278). The dysphagia symptoms were relieved after radiotherapy in all patients, and the dysphagia score was significantly higher than that before radiotherapy ( Z=6.347, P<0.001). The radiotherapy effective rates in the standard dose group and high dose group were 76.7% (23/30) and 83.3% (25/30) respectively, with no statistically significant difference ( χ2=0.417, P=0.519). The remission rates of dysphagia in the two groups were 80.0% (24/30) and 90.0% (27/30) respectively, with no statistically significant difference ( χ2=0.523, P=0.470). The incidences of adverse reactions in the two groups were 43.3% (13/30) and 83.3% (25/30) respectively, with a statistically significant difference ( χ2=10.335, P=0.001). The median overall survival in the standard dose group and high dose group were 11 months and 9 months respectively, with no statistically significant difference ( χ2=1.490, P=0.256). Conclusion:There are no statistical differences in short-time efficacy, symptom remission and long-term prognosis between the standard dose group and the high dose group in patients with advanced esophageal squamous cell carcinoma. However, the incidence of adverse reactions in patients receiving standard dose radiotherapy is low, which is worthy of clinical application.

Objective:In general, patients with seropositive rheumatoid arthritis (RA) are considered to show an aggressive disease course. However, the relationship between the two subgroups in disease severity is controversial. Our study is aimed to compare the clinical characteristics and prognosis of double-seropositive and seronegative RA in China through a real-world large scale study.Methods:RA patients who met the 1987 American College of Rheumatology (ACR) classification criteria or the 2010 ACR/European Anti-Rheumatism Alliance RA classification criteria, and who attended the 10 hospitals across the country from September 2015 to January 2020, were enrolled. According to the serological status, patients were divided into 4 subgroups [rheumatoid factor (RF)(-) anti-cyclic citrullinated peptide (CCP) antibody (-), RF(+), RF(+) anti-CCP antibody(+), anti-CCP antibody(+)] and compared the disease characteristics and treatment response. One-way analysis of variance was used for measurement data that conformed to normal distribution, Kruskal-Wallis H test was used for measurement data that did not conform to normal distribution; paired t test was used for comparison before and after treatment within the group if the data was normally distributed else paired rank sum test was used; χ2 test was used for count data. Results:① A total of 2 461 patients were included, including 1 813 RF(+) anti-CCP antibody(+) patients (73.67%), 129 RF(+) patients (5.24%), 245 RF(-) anti-CCP antibody(-) patients (9.96%), 74 anti-CCP antibody(+) patients (11.13%). ② Regardless of the CCP status, RF(+) patients had an early age of onset [RF(-) anti-CCP antibody(-) (51±14) years old, anti-CCP antibody(+) (50±15) years old, RF(+) anti-CCP antibody(+) (48±14) years old, RF(+)(48±13) years old, F=3.003, P=0.029], longer disease duration [RF(-) anti-CCP antibody(-) 50 (20, 126) months, anti-CCP antibody(+) 60(24, 150) months, RF(+) anti-CCP antibody(+) 89(35, 179) months, RF(+) 83(25, 160) months, H=22.001, P<0.01], more joint swelling counts (SJC) [RF(-) anti-CCP antibody(-) 2(0, 6), Anti-CCP antibody(+) 2(0, 5), RF(+) anti-CCP antibody(+) 2(0, 7), RF(+) 2(0, 6), H=8.939, P=0.03] and tender joint counts (TJC) [RF(-) anti-CCP antibody(-) 3(0, 8), anti-CCP antibody(+) 2(0, 6), RF(+) anti-CCP antibody(+) 3(1, 9), RF(+) 2(0, 8), H=11.341, P=0.01] and the morning stiff time was longer [RF(-) anti-CCP antibody(-) 30(0, 60) min, anti-CCP antibody(+) 20(0, 60) min, RF(+) anti-CCP antibody(+) 30(10, 60) min, RF(+) 30(10, 60) min, H=13.32, P<0.01]; ESR [RF(-) anti-CCP antibody(-) 17(9, 38) mm/1 h, anti-CCP antibody(+) 20(10, 35) mm/1 h, RF(+) anti-CCP antibody(+) 26(14, 45) mm/1 h, RF(+) 28(14, 50) mm/1 h, H=37.084, P<0.01] and CRP [RF(-) anti-CCP antibody(-) 2.3 (0.8, 15.9) mm/L, Anti-CCP antibody(+) 2.7(0.7, 12.1) mm/L, RF(+) anti-CCP antibody(+) 5.2(1.3, 17.2) mm/L, RF (+) 5.2(0.9, 16.2) mm/L, H=22.141, P<0.01] of the RF(+)patients were significantly higher than RF(-) patients, and RF(+) patients had higher disease severity(DAS28-ESR) [RF(-) anti-CCP antibody(-) (4.0±1.8), anti-CCP antibody(+) (3.8±1.6), RF(+) anti-CCP antibody(+) (4.3±1.8), RF(+) (4.1±1.7), F=7.269, P<0.01]. ③ The RF(+) anti-CCP antibody(+) patients were divided into 4 subgroups, and it was found that RF-H anti-CCP antibody-L patients had higher disease severity [RF-H anti-CCP antibody-H 4.3(2.9, 5.6), RF-L anti-CCP antibody-L 4.5(3.0, 5.7), RF-H anti-CCP antibody-L 4.9(3.1, 6.2), RF-L anti-CCP antibody-H 2.8(1.8, 3.9), H=20.374, P<0.01]. ④ After 3-month follow up, the clinical characteristics of the four groups were improved, but there was no significant difference in the improvement of the four groups, indicating that the RF and anti-CCP antibody status did not affect the remission within 3 months. Conclusion:Among RA patients, the disease activity of RA patients is closely related to RF and the RF(+) patients have more severe disease than RF(-) patients. Patients with higher RF titer also have more severe disease than that of patients with low RF titer. After 3 months of medication treatment, the antibody status does not affect the disease remission rate.

Objective:To compare the clinical efficacy of transjugular intrahepatic portosystemic shunt (TIPS) with expanded polytetrafluoroethylene (ePTFE)-covered stent and drug combined with gastroscopy as the secondary prevention of esophageal-gastric variceal bleeding in portal hypertension.Methods:Patients with esophageal-gastric variceal bleeding who received TIPS treatment (ePTFE covered stent) or gastroscopy for the first time as the secondary prevention for portal hypertension at Nanfang Hospital of Southern Medical University through March to July 2017 were selected. One year after the operation, liver function changes, ascites remission rates, incidence of hepatic encephalopathy, re-bleeding rate, average hospitalization frequency and expenses, survival time, as well as the TIPS patency conditions were analyzed in the two groups of patients. 2 test, Kaplan-Meier method and Mann-Whitney U test were used to analyze the data.Results:There were 74 and 66 cases in the TIPS and the drug combined gastroscopy group and the follow-up duration (14.57 ± 0.79) was 12-16 months. One year after surgery, the remission rate of ascites in the TIPS group was higher 57.1% (32/56) than that of the drug combined gastroscopy group (0), and the difference was statistically significant (χ 2 = 2 = 36.73, P < 0.01). The cumulative incidence of hepatic encephalopathy at 1, 3, 6, and 12 months after surgery in the TIPS group was 32.4% (24/74), 37.8% (28/74), 40.5% (30/74), and 40.5% (30/74), respectively. The cumulative incidence of hepatic encephalopathy in the drug combined gastroscopy group was 3.0% (2/66), 3.0% (2/66), 3.0% (2/66), and 6.1% (4/66), respectively. Kaplan-Meier analysis showed that the cumulative incidence of hepatic encephalopathy in the TIPS group was higher than that of the drug combined gastroscopy group (χ 2 = 11.29, P < 0.01). The incidence of severe hepatic encephalopathy ( grade III to IV) at 1, 3, 6, and 12 months after surgery in the TIPS group was 2.7% (2/74), 0, 0, and 0, respectively. The incidence of severe hepatic encephalopathy in drug combined gastroscopy group was 0, and there was no statistically significant difference in development of hepatic encephalopathy between the two groups ( P > 0.05). The re-bleeding rates of TIPS group and drug combined gastroscopy group were 0 and 27.3% (18/66), respectively, and the difference was statistically significant (χ 2 = 22.42, P < 0.01). There was no death reported during the follow-up period between both groups. The hospitalization frequency times (1.45 ± 0.80) in TIPS group was lower than that of the drug combined gastroscopy group times (3.24 ± 1.80), and the difference was statistically significant ( U = -4.52, P < 0.01). Conclusion:In the prevention of esophageal-gastric variceal bleeding, TIPS (ePTFE-covered stent) treatment has the advantages of reducing re-bleeding rate, high ascites remission rate and hospitalizations frequency. In addition, patients treated with TIPS have a higher incidence of hepatic encephalopathy than that of drugs combined with gastroscopy. However, TIPS did not exacerbate the incidence of hepatic encephalopathy, and there was no significant difference in the 1-year survival rate after TIPS and drugs combined with gastroscopy treatment.

Objective: To learn the job experience and cognition of the staff working in elderly-healthcare institutions by means of the psychological contract theory and the questionnaire so developed, for probing into the factors affecting the work recognition. Methods: The psychological contract questionnaire was used to conduct on-site questionnaires on 232 staff of such institutions in Hubei province between July 2018 and February 2019. The study covered their job experience and organizational contract, responsibility cognition. The data collected were analyzed statistically by methods such as variance analysis, descriptive statistics and related analysis. Results: It was found that personal responsibility scoring(76.0±11.8) was generally higher than organizational responsibility scoring(60.9±10.0). 46.1%(107/232) of the employees had the intention of resignation. The respondents′ resignation intention was correlated with the performance of the organization, and there was a strong correlation between employees′ career development and their resignation intention(Gamma coefficient G≥0.5). Conclusions Organizational performance needs further enhancement, and institutions should better the income distribution and incentive mechanism, and raise the income level of the staff. At the same time, the managers should optimize the institutional environment, improve the social status of the staff, strengthen career planning, training, and provide them with a more promising career development path.
