Objective To evaluate the short-term effects of comprehensive health management interventions for stroke high-risk population screening on the prevention and treatment of ischemic stroke, and to provide reference and basis for improving and exploring health management and prevention strategies for stroke high-risk population. Methods From 2018 to 2022, 13 community health service centers in Jiading District, Shanghai were selected in the present study. Based on information push platform, stroke risk assessment and health intervention follow-up were conducted for community residents through convenience sampling. The residents were divided into a full course intervention group (intervention group) and a routine intervention group (control group) according to different health intervention measures and forms. The incidence of ischemic stroke in the two groups of survey subjects was tracked within 36 months. Results A total of 52144 subjects were included in the study. The total number of patients in the full course intervention group was 14227, with an incidence density of 577.32/100 000 (556.49/100 000-598.12/100 000), which was lower than that of the conventional intervention group (37 917), with an incidence density of 1 485.47/100 000 (1 464.99/100 000-1 505.94/100 000) (χ²=2490.212, P<0.001). The relative risk of the full course intervention group was 0.39, and the relative risk of stroke risk factors in the full course intervention group from low to high was 0.33, 0.43, 0.45, and 0.49, respectively. The incidence density of males in the full course intervention group was 660.76 (627.46/100 000 - 694.05/100 000), with a relative risk of 0.43, and the incidence density of female patients was 509.71/100 000 (483.37/100 000 - 536.05/100 000), with a relative risk of 0.35. The overall incidence density of the population under 62 years old gourp, 62-75 years old group and over 75 years old group was 197.45/100 000 (173.09/100 000 -221.80/100 000), 608.36/100 000 (580.19/100 000-636.54/100 000), and 1 025.06/100 000 (958.51/100 000-1 091.61/100 000), with relative risks of 0.51, 0.44, and 0.38, respectively. Conclusion Comprehensive health management measures can effectively reduce the short-term risk of ischemic stroke, and should be further promoted and improved to enhance the effectiveness of stroke prevention and control.

ObjectiveTo compare colonoscopy compliance rates under different screening strategies, to explore ways to enhance colonoscopy compliance among residents with colorectal carcinoma. MethodsResidents aged between 50‒80 years were recruited through extensive community outreach and voluntary participation. A total of 210 630 residents who participated in the colorectal carcinoma screening program in Jiading District, Shanghai, between 2013 and 2019 were selected as the research subjects. All subjects underwent a colorectal carcinoma risk assessment questionnaire survey and two fecal occult blood tests (FOBT). Positive results in the initial screening were defined as a positive questionnaire survey or a positive result in at least one FOBT. Participants with positive initial screening results were advised to undergo colonoscopy screening in a hospital. Colonoscopy results were collected from hospital reports and physician follow-ups. Compliance with colonoscopy was analyzed under different screening strategies to identify possible factors influencing residents’ willingness to undergo the procedure. ResultsA total of 21 403 individuals (10.16%) were identified as positive with the questionnaire survey, 31 595 individuals (15.00%) tested positive with at least one FOBT. Combined questionnaire and FOBT positivity was observed in 3 501 individuals (1.66%). Among the 48 453 individuals with positive initial screening results, 17 230 (35.56%) underwent colonoscopy, and a total of 315 cases of colorectal cancer were detected. The sensitivity, specificity value of FOBT initial screening were 83.81% and 84.66%, respectively. According to the combined risk assessment and FOBT initial screening preliminary screening, the lowest colonoscopy compliance rate (25.63%) was observed among individuals with only a positive questionnaire, and the highest compliance rate (52.55%) was among those with both positive questionnaire survey and two positive FOBT results. Multivariate analysis revealed that FOBT positivity had the greatest impact on colonoscopy compliance. Those with one positive FOBT test result were 2.64 times more likely to undergo colonoscopy screening than those with negative FOBT results, while individuals with two positive FOBT results were 3.18 times more likely to do so. After adjusting for FOBT results, individuals with positive questionnaire survey results were 1.43 times more likely to undergo colonoscopy screening than those with negative results (95%CI: 1.34‒1.52). Compared to questionnaire-based risk assessment, FOBT results were more influential in determining compliance with colonoscopy. ConclusionThe choice of initial screening method significantly impacts residents’ compliance with colonoscopy. While implementing colorectal carcinoma screening programs, it is necessary to strictly adhere to screening protocols, including risk assessment and FOBT. Additionally, efforts should be made to raise public awareness, encouraging residents to actively participate in risk assessments and FOBT, thereby improving their compliance with colonoscopy.

ObjectiveTo investigate the effects of Tongxinluo capsules on traditional Chinese medicine （TCM） syndrome elements and major adverse cardiovascular events （MACEs） in patients with chronic coronary syndrome of Qi deficiency and blood stasis type. MethodsA multicenter and prospective cohort study was conducted. The intervention of Tongxinluo Capsules was used as the exposure factor， and the patients were divided into an exposure group （integrated traditional Chinese and western medicine treatment group） and a non-exposure group （western medicine treatment group）. The patients were followed up for one year. The TCM syndrome element scores were assessed by using a syndrome element diagnosis scale on the day of enrollment and in the third， sixth， and twelfth months， and the incidence of MACE within one year was recorded. ResultsA total of 186 patients were included， with 128 patients in the exposure group and 58 patients in the non-exposure group. There was no significant difference in baseline data between the two groups. Compared with those in the pretreatment period for each group， the Qi deficiency and blood stasis syndrome scores in the treatment and follow-up period were significantly improved （P<0.05）. Compared with the non-exposure group， the exposure group exhibited significantly decreased Qi deficiency syndrome scores in the treatment and follow-up period （P<0.01） and significantly reduced blood stasis syndrome scores in the sixth month （P<0.05）. In the remaining follow-up period， there was no statistically significant difference between the two groups. Compared with that of the non-exposure group， during the treatment period （the third month）， the difference in Qi deficiency and blood stasis syndrome scores of the exposure group was statistically significant （P<0.05， P<0.01）. At the end of the follow-up period， patients in the non-exposure group had a MACE probability of 6.90% （4/58）， higher than 3.13% in the exposure group （4/58）. Compared with patients with angina pectoris who used conventional medicine， patients administered with Tongxinluo Capsules had a relative risk（RR） of 0.45 ［95%confidence interval（95%CI） 0.12-1.75， P=0.26］. There was no significant difference in the incidence of MACE within one year between the two groups. ConclusionTongxinluo capsules can improve the degree of Qi deficiency in patients with chronic coronary syndrome in the short term， and the improvement effect of blood stasis syndrome appears in the medium and long term. They can better improve the Qi deficiency syndrome in the long term. Within one year， the incidence of MACE in the exposure group was lower than that in the non-exposure group.

Objective:To systematically analyze the incidence and influencing factors of frailty in elderly patients with hematologic malignancies.Methods:Research on frailty in elderly patients with hematologic malignancies was retrieved from Chinese and English databases such as China National Knowledge Infrastructure, Wanfang Data, PubMed, and Web of Science. The search period was from database establishment to August 23, 2024. Two researchers screened the included studies, conducted quality assessment, and extracted data. Meta-analysis was conducted using Stata 18 and RevMan 5.4.Results:A total of seven studies were included, encompassing 19 076 elderly hematologic malignancy patients, with a frailty incidence of 59% [95% CI (0.48, 0.69) ]. Meta-analysis revealed that age [ MD=4.31, 95% CI (3.67, 4.96) ], gender [ OR=0.88, 95% CI (0.83, 0.93) ], alcohol consumption [ OR=1.67, 95% CI (1.15, 2.44) ], self-care ability [ MD=-1.79, 95% CI (-3.17, -0.41) ], anemia [ OR=6.67, 95% CI (2.94, 15.14) ], infection [ OR=1.81, 95% CI (1.16, 2.84) ], and neuropathy [ OR=2.52, 95% CI (1.38, 4.61) ] were the influencing factors of frailty in elderly patients with hematologic malignancies. Conclusions:The incidence of frailty is high in elderly patients with hematologic malignancies. Elderly patients with hematologic malignancies who are older, female, consume alcohol, have low self-care ability, anemia, infections, and neuropathy are prone to frailty. Healthcare providers can conduct early screening and intervention for high-risk populations of frailty based on risk factors to improve the quality of life for elderly hematologic malignancy patients.

OBJECTIVE To study the effects of Ro 64-6198,a selective nociceptin/orphanin FQ receptor(NOPR)agonist,on heroin self-administration and drug-seeking behavior in rats.METHODS Rats were trained to self-administer heroin intravenously at a dose of 0.05 mg·kg-1 under a fixed ratio 1(FR1)reinforcement schedule.Heroin motivation was assessed using a progressive ratio(PR)schedule.Firstly,a stable heroin self-administered rat model was established before the effects of Ro 64-6198 on heroin rewarding under the FR1 schedule were observed.After three days of self-administration recovery training,the effects of Ro 64-6198 on heroin reward motivation were observed under the PR3-4 schedule.Following extinction,the reinstatement of heroin seeking induced by either conditioned cues or heroin priming was evaluated in rats withdrawn from self-administration.The expressions of cAMP response element-binding protein(CREB)and brain-derived neurotrophic factor(BDNF)in the ventral tegmental area(VTA)were analyzed using Western blotting,while the expression of the NOPR in neurons in the VTA was examined through immunofluorescence staining.RESULTS Pretreatment with 3 mg·kg-1 Ro 64-6198 significantly reduced active responses and heroin infusions during FR1 testing,as well as decreased breakpoints,indicating reduced motivation under the PR schedule.At a dose of 1 mg·kg-1,Ro 64-6198 markedly attenuated the reinstatement of heroin-seeking behavior induced by conditioned cues or heroin priming.Furthermore,the administration of SB-612111,an NOPR antagonist,blocked the inhibitory effects of Ro 64-6198 on cue-induced heroin-seeking,although SB-612111 alone had no effect on heroin-seeking behavior.Ro 64-6198 treatment also suppressed the reduction of both phos-phorylated CREB(p-CREB)and BDNF levels in the VTA and the decreased expression of NOPR and p-CREB in dopaminergic neurons of the VTA.CONCLUSION These results demonstrate that Ro 64-6198 can mitigate heroin-seeking behavior through NOPR activation and CREB/BDNF pathway in the VTA.This study is expected to offer evidence for its potential as a clinical treatment for heroin addiction and relapse.

Pharmacoepidemiology is an interdisciplinary field that applies epidemiological methods to study drug use,effectiveness,and associated risk in populations.Standardizing research methods in this field is crucial for ensuring research quality and promote the development of the discipline.Based on the Guide on Methodological Standards in Pharmacoepidemiology in China(2nd edition),this article interprets the relevant contents about classic research types and their derivative designs.It aims to clarify the types of study methodological designs in pharmacoepidemiology,systematically describe the characteristics and applications classical derivative designs,and compare these with research design frameworks outlined in international pharmacoepidemiological guidelines.Compared to the first edition,the second edition of the guideline has updated and detailed the types of research,updating the research design to original research(interventional research and non-interventional research),secondary research(systematic review,Meta-analysis,economic analysis,etc.),and tertiary research(umbrella review,etc.).Additionally,a variety of derivative designs have been added,including target trial emulation,nested case-control and case-cohort studies,case-crossover designs,self-controlled case series and self-controlled risk interval designs,case-population studies,interrupted time-series analysis,and case-coverage(ecological)designs for vaccine surveillance.This article strengthens the operability of the theoretical guidance of pharmacoepidemiological research methods in practice and provides a reference for conducting high-quality pharmacoepidemiological research.

Objective:To evaluate the efficacy and safety of IBUCy(idarubicin,busulfan,and cyclophosphamide)and FABC(fludarabine,cyta-rabine,busulfan,and cyclophosphamide)conditioning regimens followed by allogeneic hematopoietic stem cell transplantation(allo-HSCT)for the treatment of medium-to-high risk acute myelocytic leukemia(AML).Methods:We retrospectively analyzed data of 49 patients with medium-to-high risk AML who received IBUCy(n=17)or FABC(n=32)conditioning regimens followed by allo-HSCT between January 2015 and December 2021 at The First Affiliated Hospital of Chongqing Medical University.Hematopoietic reconstruction time,adverse events,and survival outcomes were compared between the two groups to assess the efficacy and safety of the two regimens.Additionally,we analyzed factors that may be associated with prognosis.Results:Hematopoietic reconstruction was successful in all 49 patients.No significant differ-ences were observed between the two groups in terms of hematopoietic reconstruction time.Similarly,no significant differences were ob-served in the 5-year progression-free survival(PFS)and overall survival(OS)rates between the two groups.The incidence rates of oral mu-cositis,nausea and vomiting,diarrhea(≥grade 3 based on CTCAE v5.0),and chronic graft-versus-host disease(GVHD)were significantly high-er in the IBUCy group than that in the FABC group.However,the incidence rate of hemorrhagic cystitis in the FABC group was significantly higher than that in the IBUCy group.The time from diagnosis to allo-HSCT>6 months and being minimal residual disease(MRD)-positive be-fore transplantation were identified as the risk factors for PFS(P=0.019 and P=0.048,respectively).Patients who were MRD-negative before transplantation had significantly longer PFS when treated with the IBUCy conditioning regimen(P=0.039).Conclusions:Both IBUCy and FABC conditioning regimens prior to allo-HSCT are safe and effective for treating medium-to-high risk AML.Allo-HSCT should be performed as soon as possible when patients achieve their first complete remission.Patients with an MRD-negative status before transplantation tend to have longer PFS.Compared with the FABC regimen,the IBUCy regimen has some advantages;however,attention should be given to the prevention and management of gastrointestinal adverse events and chronic GVHD.
