Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

Objective To explore the effect of the long non-coding RNA,Opa interacting protein 5-antisense RNA 1(OIP5-AS1),on colorectal cancer metastasis and elucidate the underlying mechanisms.Methods OIP5-AS1 expression levels were analyzed in various colorectal cancer cell lines(SW480,HCT116,HT-29,and Caco-2)via real-time polymerase chain reaction.Cell lines with high OIP5-AS1 expression levels were selected and randomly transfected with the control sequence(NC group),interference sequence 1(OIP5-AS1 siRNAl group),or interference sequence 2(OIP5-AS1 siRNA2 group).Transwell assay was used to assess cell migration.Additionally,the effects of OIP5-AS1 on the expression levels of epithelial-mesenchymal transition-related proteins,including E-cadherin,N-cadherin,and Vimentin,were examined via Western blotting.Immunofluorescence assay was used to evaluate the effects of OIP5-AS1 on the pro-tein expression levels and cellular localization of E-cadherin and N-cadherin.Results Expression levels of OIP5-AS1 were significantly higher in the SW480 and HCT116 highly invasive cell lines than in the HT-29 and Caco-2 low invasive cell lines(P＜0.05).OIP5-AS1 silencing decreased cell migration,increased E-cadherin levels,and decreased N-cadherin and Vimentin levels in SW480 and HCT116 cells.Conclusion Our findings suggest that OIP5-AS1 promotes metastasis by inducing epithelial-mesenchymal transition and migration of colorectal cancer cells.

Objective:To compare the effects of intensive and standard blood pressure control on the outcomes of patients with acute ischemic stroke in the anterior circulation who have successfully recanalized after endovascular therapy (EVT).Methods:A multicenter, open-label, blinded-endpoint, randomized controlled design was used. Patients with anterior circulation stroke received EVT and successfully recanalized in Nanjing First Hospital, Nanjing Medical University and several branch hospitals from July 2020 to October 2022 were prospectively included. They were randomly divided into the intensive blood pressure control group (target systolic blood pressure [SBP] 100-120 mmHg) or the standard blood pressure control group (target SBP 121-140 mmHg). The blood pressure of both groups needs to achieve the target within 1 h and maintain for 72 h. The primary outcome endpoint was outcome at 90 d, and the good outcome was defined as a score of 0-2 on the modified Rankin Scale. Secondary outcome endpoints included early neurological improvement, symptomatic intracranial hemorrhage (sICH) within 24 h, and death and serious adverse events within 90 d.Results:A total of 120 patients were included, including 63 in the intensive blood pressure control group and 57 in the standard blood pressure control group. There was no statistically significant difference in baseline characteristics between the two groups. The SBP at 72 h after procedure was 122.7±8.1 mmHg in the intensive blood pressure control group and 130.2±7.4 mmHg in the standard blood pressure control group, respectively. There were no significantly differences in the good outcome rate (54.0% vs. 54.4%; χ2=0.002, P=0.963), the early neurological improvement rate (45.2% vs. 34.5%; χ2=1.367, P=0.242), the incidence of sICH (6.3% vs. 3.5%; P=0.682), mortality (7.9% vs. 14.0%; χ2=1.152, P=0.283) and the incidence of serious adverse events (12.7% vs. 15.8%; χ2=0.235, P=0.628) at 90 d between the intensive blood pressure control group and the standard blood pressure control group. Conclusion:In patients with anterior circulation stroke and successful revascularization of EVT, early intensive blood pressure control don’t improve clinical outcomes and reduce the incidence of sICH.

Objective:To investigate the unqualified hepatitis C virus (HCV) detection result of blood donors from the served area of blood institutions.Methods:The data related to HCV markers detected of the first and repeat blood donors were collected from the system of practice comparison for the Chinese mainland blood institutions from 2017 to 2021. The anti-HCV reactive rate and the rates of anti-HCV negative but HCV-RNA reaction and all the relationship between rates and the annual, regional and different blood donors were statistically analyzed.Results:During 2017-2021, the number of anti-HCV reactive per 100 000 blood donors decreased from 444.3 to 250.44 in the served area of 22 blood institutions ( χ2=49.677, P<0.05). The number of HCV RNA detected positive per 100 000 anti-HCV negative increased from 0.69 to 2.05 year by year, but there was no statistical significance ( χ2=0.643, P>0.05). The anti-HCV unqualified rate was significantly different among regions ( χ2=3 260.283, P<0.05). The anti-HCV unqualified rate of the first blood donors was significantly higher than that of the repeated blood donors ( F=130.993, P < 0.05). The annual number of HCV RNA detected positive per 100 000 anti-HCV negative blood samples from donors ranged from 0 to 17.28. Conclusions:The anti-HCV unqualified rate of blood donors in the served area of 22 blood institutions decreased year by year. Compared with repeated blood donors, HCV infection should be emphasized in first-time blood donors. The implementation of HCV RNA test can detect out much more HCV infections and reduce the risk of transfusion transmitted infectious HCV.

Objective:To investigate the safety of the use of the intermediate catheter in the endovascular treatment (EVT) of patients with acute anterior circulation large vessel occlusive stroke and its impact on the outcomes.Methods:From May 2015 to September 2018, patients with anterior circulation large vessel occlusive stroke received EVT in Nanjing First Hospital, Nanjing Medical University were enrolled retrospectively. According to whether intermediate catheter was used during the procedure, they were divided into intermediate catheter group and non-intermediate catheter group. The demographics, clinical data and procedure related information were collected. The outcome evaluation indicators included secondary embolization, symptomatic intracranial hemorrhage, clinical outcome and death at 90 d after onset. A good outcome was defined as the modified Rankin Scale score of 0-2. Multivariate logistic regression analysis was used to determine the independent predictor of clinical outcome. Results:A total of 195 patients with anterior circulation large artery occlusive stroke received EVT were enrolled, including 161 in the intermediate catheter group and 34 in the non-intermediate catheter group. There were no significant differences in demographics and clinical characteristics between the intermediate catheter group and the non-intermediate catheter group. In terms of procedure related information, the number of mechanical thrombectomy passes in the intermediate catheter group was significantly decreased (2 [1-3] times vs. 2.5 [1.75-4] times; Z=2.218, P=0.017), the recanalization rate of one-pass thrombectomy was significantly higher (38.5% vs. 20.6%; χ2=3.943, P=0.047), and the rate of thrombus escape and secondary embolism was significantly lower (19.3% vs. 35.3%; χ2=4.202, P=0.041). In terms of clinical outcome, there were no significant differences in the incidence of symptomatic intracranial hemorrhage, mortality and good outcome at 90 d between the intermediate catheter group and the non-intermediate catheter group. Multivariate logistic regression analysis showed that the use of intermediate catheter was an independent predictor of good outcome at 90 d (odds ratio 0.430, 95% confidence interval 0.196-0.947; P=0.036). Conclusion:In EVT of patients with acute anterior circulation large vessel occlusive stroke, the use of intermediate catheter can reduce the number of mechanical thrombectomy passes, improve recanalization rate of one-pass thrombectomy, reduce the rate of thrombus escape and second embolization, and then improve the outcome of patients.

Community health institutions have entered a new development stage of featured specialty construction. After 12 years of development, rehabilitation medicine now is the featured specialty of Fenglin Community Health Service Center. This article presents the train of thought and key points of specialty construction in primary care institutions based on the Fenglin′s experience. The positioning of featured specialty should be based on the community. The construction process should include 7 elements, namely, the standard operation procedure(SOP)of service system construction, the detailed publicity and implementation of the collaboration of specialists, prevention and control knowledge promotion for general practitioners, prevention and control knowledge education for community residents, service list, clinical efficacy evaluation, and clinical database. In the later iterations, the head of the department should always focus on the service system construction SOP and clinical database construction, and the rest parts can be assigned to the relevant team members.

The construction of featured specialties is the current development strategy of community health service institutions to improve the service scope and to meet the health needs of residents. The rehabilitation medicine has undergone 12 years of development and become a relatively mature featured specialty in Fenglin Community Health Service Center. Based on the Fenglin′s experience, this article discusses the development status and restriction bottlenecks of general practice, and the development status and trend of rehabilitation medicine in the community; and also explores the integrated development model of community-featured specialty with general practice.

Objective: To compare the effects of modified Thrombolysis in Cerebral Infarction score (mTICI) 2b and mTICI 3 reperfusion on lesions′ changes and prognosis in patients who underwent endovascular therapy within six hours after onset. Methods: A retrospective analysis was conducted on 94 patients with acute large intracranial artery occlusion of the anterior circulation who achieved reperfusion sucesssfully by endovascular therapy within 6 hours after onset in the Department of Neurology, Nanjing First Hospital from October 2016 to March 2019. The effects of mTICI 2b and mTICI 3 reperfusion on lesions′ changes and prognosis of patients were compared. The primary endpoint was the modified Rankin Scale (mRS) score at 90 days; the secondary endpoints were the early neurological deficit score, the mortality at 90 days, the volume of infarction at 24 hours, the changes in infarct volume for 24 hours and the rate of symptomatic intracerebral hemorrhage (sICH) , reocclusion and hemorrhagic transformation. Results: In all patients, 35 cases received mTICI 2b reperfusion and 59 cases received mTICI 3 reperfusion. Compared with mTICI 2b group (10.00 (3.00, 16.00)), the early neurological deficit score at seven days of mTICI 3 group (6.00 (1.00,11.50)) was lower (Z=-2.004, P=0.045) . However, there were no statistically significant differences in mRS score at 90 days, early neurological deficit score at 24 hours and 3 days, mortality at 90 days, volume of infarction at 24 hours, the changes in infarct volume for 24 hours, and the rate of sICH, reocclusion, and hemorrhagic transformation between the two groups. Conclusion For patients with large intracranial artery occlusion of the anterior circulation within six hours after onset, achieving mTICI 3 reperfusion after endovascular therapy can improve the early neurological function more effectively, but the effects on 90-day functional outcome are similar to that of mTICI 2b reperfusion.

Objective: To investigate the effect of the time from onset to recanalization on the outcomes after endovascular treatment (EVT) in patients with acute stroke due to posterior circulation large vessel occlusion. Methods: From May 2015 to May 2019, patients with acute ischemic stroke due to posterior circulation large vessel occlusion receiving EVT in the Department of Neurology, Nanjing First Hospital, Nanjing Medical University were enrolled retrospectively. According to the modified Rankin Scale (mRS) score at 90 d after procedure, they were divided into good outcome group (≤2) and poor outcome group (>2). Demographic and clinical data were compared between the two groups. Multivariate logistic regression analysis was used to determine the independent correlation between the time from onset to recanalization and the outcomes. Results: A total of 64 patients with acute ischemic stroke due to posterior circulation large vessel occlusion treated by EVT were enrolled in this study. There were 50 males (78.0%) and 14 females (22.0%). The age was 67.52±10.30 years. The National Institutes of Health Stroke Scale (NIHSS) score was 22.04±4.17, and the time from onset to recanalization was 370.53±78.59 min. Thirty-one patients (48.0%) were in the good outcome group and 33 (52.0%) were in the poor outcome group. There were significant differences in baseline NIHSS score, systolic blood pressure, time from onset to revascularization, and the proportions of patients with tandem lesion and symptomatic intracranial hemorrhage between the two groups (all P<0.05). Multivariate logistic regression analysis showed that the longer time from onset to recanalization (odds ratio [OR] 1.317, 95% confidence interval [CI] 1.001-3.034; P=0.041) and symptomatic intracranial hemorrhage (OR 4.207, 95% CI 1.931-10.761; P=0.004) were the independent predictors of poor outcomes, while the lower baseline NIHSS score (OR 0.302, 95% CI 0.056-0.743; P=0.047) was the independent protective factor of poor outcomes. Conclusions The longer time from onset to recanalization is an independent risk factor for poor outcomes after EVT in patients with acute ischemic stroke caused by posterior circulation large vessel occlusion.

Objective To investigate the effect and safety of intravenous thrombolytic therapy in the endovascular treatment of acute anterior circulation vascular occlusive stroke.Methods The clinical data of 226 patients with acute anterior circulation vascular occlusive stroke who underwent endovascular treatment in Nanjing First Hospital,Nanjing Medical University from May 2015 to May 2018 were retrospectively collected.According to whether or not intravenous thrombolysis was performed,the patients were classified into simple thrombectomy group (n=112) and bridging treatment group (n=114).The modified Thrombolysis in Cerebral Infarction Score (mTICI) was used to evaluate the vascular opening effect,and the blood vessel recanalization time,mTICI,the symptomatic intracranial hemorrhage rate,and the modified Rankin Scale (mRS) score at 90 days after surgery were evaluated.Results There were no statistically significant differences in gender,age,past history and National Institute of Health Stroke Scale score between the two groups (P＞0.05).There was no statistically significant difference in door-to-recanalization time between the two groups (P＞0.05).Excluding the patients with post-wake stroke and unexplained onset time,the simple thrombectomy group (n=63) and the bridging treatment group (n=1 11) showed statistically significant differences in onset-to-door time ((235.04± 182.64) min vs (102.48±60.51) min,t=7.01,P＜0.01)and onset-to-recanalization time ((405.31 ± 148.89) min vs (337.31 ± 117.65) min,t=3.32,P=0.01).The difference in number of thrombectomy between the simple thrombolysis group (2.55± 1.52) and the bridging treatment group (2.11± 1.48) was statistically significant (t=2.246,P=0.026).The total reperfusion (mTICI 2b/3) rate was 89.8％ (203/226),88.4％ (99/112) in the simple thrombectomy group and 91.2％ (104/114) in the bridging treatment group,with no statistically significant difference between the two groups (P＞0.05).The differences in symptomatic intracranial hemorrhage rate (8.93％ (10/112) vs 11.4％ (13/114)),mortality rate (12.5％ (12/112) vs 16.7％ (19/114)) and 90-day good functional outcome (mRS score 0-2;54.5％ (61/112) vs 55.8％ (63/114)) between the two groups were not statistically significant (P＞0.05).Conclusions In patients with acute anterior circulation vascular occlusive stroke undergoing endovascular treatment,intravenous thrombolysis can reduce the number of thrombectomy,not increase the door-to-recanalization time,the risk of symptomatic intracranial hemorrhage and mortality,and has similar good functional outcome as the simple thrombeetomy group.Therefore,intravenous thrombolysis is safe and effective for endovascular treatment of acute anterior circulation large vessel occlusive stroke.
