RESUMEN
ObjectiveThe traditional Chinese medicine Strychnos nux-vomica L. (SN) has the clinical effect of reducing swelling and relieving pain; however, SN is toxic due to its alkaloid components. Little is known about the endogenous metabolic changes induced by SN toxicity in rats and their potential effects on the metabolic dysregulation of intestinal microbiota. Therefore, toxicological investigation of SN is of great significance to its safety assessment. In this study, the toxic mechanisms of SN were explored using a combination of metabonomics and 16S rRNA gene sequencing. MethodsThe toxic dose, intensity, and target organ of SN were determined in rats using acute, cumulative, and subacute toxicity tests. UHPLC-MS was used to analyze the serum, liver, and renal samples of rats after intragastric SN administration. The decision tree and K Nearest Neighbor (KNN) model were established based on the bootstrap aggregation (bagging) algorithm to classify the omics data. After samples were extracted from rat feces, the high-throughput sequencing platform was used to analyze the 16S rRNA V3-V4 region of bacteria. ResultsThe bagging algorithm improved the accuracy of sample classification. Twelve biomarkers were identified, where their metabolic dysregulation may be responsible for SN toxicity in vivo. Several types of bacteria such as Bacteroidetes, Anaerostipes, Oscillospira and Bilophila, were demonstrated to be closely related to physiological indices of renal and liver function, indicating that SN-induced liver and kidney damage may be related to the disturbance of these intestinal bacteria. ConclusionThe toxicity mechanism of SN was revealed in vivo, which provides a scientific basis for the safe and rational clinical use of SN.
RESUMEN
OBJECTIVE To evaluate the medication adherence of patients with hypertension in medication consultation clinics, and to analyze its influencing factors. METHODS The data of 389 patients who visited the medication consultation clinics of our hospital from June 2021 to June 2023 were collected. Univariate and multivariate Logistic regression analysis were used to analyze the related factors affecting medication adherence of hypertensive patients or those receiving different types of drugs. RESULTS Among 389 patients with hypertension, 302 cases (77.63%) had good adherence. Multivariate Logistic analysis showed that higher education level [corrected OR=2.25, 95%CI (1.29, 3.93), P=0.004] was positively correlated with medication adherence, average blood pressure level [corrected OR=0.19, 95%CI (0.10, 0.37), P<0.001], without complication [corrected OR=0.47, 95%CI(0.26,0.84),P=0.010] and antihypertensive drug regimen being free dose combination [corrected OR=0.27,95%CI(0.15, 0.47), P<0.001] were negatively correlated with adherence. Results of univariate Logistic regression analysis showed that patients who used β-receptor blocking agents [OR=1.65,95%CI(1.06,2.57),P=0.027], calcium channel blockers [OR=2.13,95%CI(1.33, 3.42),P=0.002] and agents acting on the renin-angiotensin system [OR=2.04,95%CI(1.29,3.22),P=0.002] had good medication adherence. CONCLUSIONS The medication adherence of hypertension patients needs to be improved. Hypertension patients with higher education level, lower average blood pressure level, complications and fixed-dose combination regimen and those who use agents acting on the renin-angiotensin system, calcium channel blockers and β-receptor blocking agents may have better medication adherence.

RESUMEN
ObjectiveTo investigate the association between ZJU index and the onset of nonalcoholic fatty liver disease (NAFLD) in the Uygur population and the value of ZJU index in predicting the risk of NAFLD. MethodsThe Uighur community of The 51st Regiment of The Third Division of Xinjiang Kashgar Corps was selected as the investigation site, and the Uygur residents who lived in this area and had an age of >18 years were selected as subjects. Follow-up studies were conducted in 2019, 2020, and 2021, and the investigation of outcomes was completed in June to August of 2021. Finally 10 597 subjects were enrolled for analysis. The Kruskal-Wallis H test was used for comparison of continuous variables between groups, and the chi-square test was used for comparison of categorical variables between groups. The subjects were divided into Q1-Q4 groups according to the level of ZJU index. The Kaplan-Meier curve was used to predict the incidence rate of NAFLD, and the Cox regression model was used to analyze the association between ZJU index and the risk of NAFLD; the area under the ROC curve (AUC) was used to evaluate the value of ZJU index in predicting the risk of NAFLD. ResultsDuring the median follow-up time of 4.92 years, the incidence rate of NAFLD was 9.4% (992/10 597) among the study population. After adjustment for multiple factors, there was a significant increase in the risk of NAFLD with the increase in ZJU index, with a hazard ratio of 2.55 (95% confidence interval [CI]: 1.60 — 4.06), 7.32 (95%CI: 4.78 — 11.20), and 21.74 (95%CI: 14.32 — 33.00), respectively (all Ptrend<0.001). The ROC curve showed that ZJU index had a higher value in predicting NAFLD (AUC=0.816), and the male subgroup had a significantly higher predictive accuracy of ZJU index than the female subgroup (AUC: 0.829 vs 0.809). ConclusionZJU index is a predictive factor for the onset of NAFLD in the Uygur population in rural areas of Xinjiang and has a good value in predicting the risk of NAFLD.
RESUMEN
Objective:To explore the epidemiology, clinical features and prognosis of pseudorabies virus (PRV) infection in human.Methods:A case of human PRV encephalitis combined with acute retinal necrosis (ARN) in the First Affiliated Hospital of Zhengzhou University in May 2020 was reported. The epidemiology, clinical features, neuroimaging, cerebrospinal fluid (CSF), next-generation sequencing (NGS), treatment and prognosis of human PRV infection were summarized and analyzed with the previous published data.Results:The present case was a 38-year-old man who developed high fever, headache, cognitive decline, recurrent epileptic seizures after butchering a pig. Brain magnetic resonance imaging showed lesions in the insular lobes, temporal lobes, cingulate gyrus, frontal lobes, basal ganglia and hippocampus, with more significant signals on the left side. Afterwards, bilateral ARN occurred and resulted in his blindness. PRV DNA was detected from the aqueous humor. By literature review, a total of 20 cases (including this case) were analyzed. Most patients (95%, 19/20) had the history of direct contact with swine. The median incubation period was 7 days. The infection normally caused encephalitis (95%, 19/20), some cases with endophthalmitis (60%, 12/20). Based on the neuroimaging of the 19 patients, the lesions in neuroimaging were mainly in limbic system, especially in insular (17/19) and temporal lobes (17/19). The basal ganglia was often involved (9/19).The PRV-DNA was detected by NGS in CSF or intraocular fluid. Antiviral drugs and adjuvant treatment, including immunoglobulin and/or corticoid therapy, were effective to only few cases. Most patients (90%, 18/20) had the sequelae of severe impairment of daily living (modified Rankin Scale scores≥3).Conclusions:The cardinal clinical characteristics of human PRV infection are progressive panencephalitis and endophthalmitis, with an unfavorable outcome. The history of exposure to sick swine and typical neuroimaging suggest PRV infection. NGS of CSF and/or intraocular fluid is the dependable diagnostic method.
RESUMEN
AIM: To investigate the effect of nasolacrimal duct packing combined with sodium hyaluronate gel injection in locating the nasal broken end in lacrimal canaliculus anastomosis which is difficult to find the broken end.METHODS:A total of 13 patients(13 eyes)with traumatic single lacrimal canaliculus rupture were treated in our hospital. RS lacrimal duct drainage tube was inserted into the lacrimal duct from intact lacrimal canaliculus to fill the nasolacrimal duct, then sodium hyaluronate gel was injected to make sodium hyaluronate gel overflow from the nasal broken end of fractured lacrimal canaliculus, which was used to locate the nasal broken end which was difficult to find and completed the lacrimal anastomosis operation.RESULTS: Among the patients with 13 eyes who were difficult to find the broken end, the nasolacrimal duct was filled with RS lacrimal duct drainage tube. After injection of sodium hyaluronate gel, the gel overflowed from the nasal broken end under direct vision of the microscope, and the lacrimal duct drainage tube was successfully inserted, and the success rate of finding the broken end was 100%. Thirteen eyes were extubated after being placed for 3mo, and then were followed up for 6mo. Among them, 9 eyes were cured, 3 eyes were markedly effective and 1 eye was ineffective. The cure rate was 69%, and the total effective rate was 92%.CONCLUSION: A new technique for rapid location of nasal broken end is proposed for patients in which are difficult to find the broken end. This method is simple to operate and requires a relatively low clinical experience. It is suitable for patients with different degrees of single lacrimal canaliculus rupture and can complete complex lacrimal canaliculus rupture anastomosis in a short time.
RESUMEN
Objective To investigate the comorbidity of hepatic cystic echinococcosis with HBV/HCV infection, liver cirrhosis, and hepatocellular carcinoma, and to lay a foundation for further research on the influence of hepatic cystic echinococcosis on HBV/HCV infection, liver cirrhosis, and hepatocellular carcinoma. Methods A retrospective analysis was performed for the data of 401 patients with hepatic cystic echinococcosis who were admitted to The First Affiliated Hospital of Shihezi University from 2003 to 2019, and the state of comorbidity of hepatic cystic echinococcosis with HBV/HCV infection, liver cirrhosis, and hepatocellular carcinoma was clarified. The patients with hepatic cystic echinococcosis and chronic HBV/HCV infection were selected as comorbidity group, and the patients with HBV/HCV infection alone were matched as control group. The chi-square test and the Fisher's exact test were used to analyze the state of viral infection and the disease composition of liver cirrhosis and hepatocellular carcinoma. Results Of all 401 patients, 38(9.5%) were included in the comorbidity group and 2(0.5%) had liver cirrhosis after HBV/HCV infection, while no patient had hepatocellular carcinoma after HBV/HCV infection. Among the patients with chronic hepatitis B virus infection in the comorbidity group, non-active HBsAg carriers accounted for 81%, HBeAg-positive chronic hepatitis B patients accounted for 9.5%, and HBeAg-negative chronic hepatitis B patients accounted for 9.5%; among the patients with hepatitis B virus infection in the control group, non-active HBsAg carriers accounted for 43%, HBeAg-positive chronic hepatitis B patients accounted for 33%, and HBeAg-negative chronic hepatitis B patients accounted for 19%, with a significant difference between the two groups ( P =0.033). There was a significant difference in the HBV RNA clearance rate of the patients with HCV infection between the comorbidity group and the control group ( χ 2 =4.447, P =0.035). In the comorbidity group, the patients with liver cirrhosis accounted for 5.2% and there were no patients with hepatocellular carcinoma, while in the control group, the patients with liver cirrhosis accounted for 18.4% and those with hepatocellular carcinoma accounted for 5.2%; the comorbidity group had significantly lower proportions than the control group ( P =0.048). Conclusion The proportion of liver cirrhosis patients with hepatic cystic echinococcosis and HBV/HCV infection is lower than that of liver cirrhosis patients with viral hepatitis alone, and there are no cases of hepatocellular carcinoma after HBV/HCV infection. Further multicenter studies are needed to investigate the influence of hepatic cystic echinococcosis on chronic HBV/HCV infection, liver cirrhosis, and hepatocellular carcinoma.
RESUMEN
To evaluate the efficacy and safety of left atrial appendage occlusion (LAAO) in patients with atrial fibrillation (AF) over 75 years. A total of 82 patients with AF who underwent LAAO successfully in Beijing Anzhen Hospital from March 2014 to March 2019 were divided into two groups according to age: the elderly group (aged>75 years) and the young group (aged ≤75 years). Risk of perioperative complications and incidence of ischemic stroke and major bleeding during follow-up were retrospectively analyzed. The results showed that there were no significant differences in procedure-related ischemic stroke(0 vs.1.6%, P=0.768) and major bleeding (0 vs.1.6%, P=0.768) during perioperative period between the two groups. No complications as death or pericardial tamponade occurred in the two group. During a (25.9±15.9) months period of followed up, ischemic stroke event rate was 3.6/100 person-years in the elderly group and 4.9/100 person-years in the young group, respectively. Major bleeding event rate was 2.5/100 person-years in the elderly group and 0/100 person-years in the young group, respectively. Compared with the expected ones, the relative risk reduction (RRR) of stroke in the elderly group was more profound than that in the young group (32.0% vs. 25.0%), while the risk of major bleeding in the young group was significantly lower than that in the elderly group (RRR 100% vs. 56.9%). Therefore, LAAO might be suitable for stroke prevention in the elderly AF patients.

Objective:To investigate the relationship between serum procollagen Ⅲ amino terminal peptide (PIIINP), collagen I carboxyl terminal cross-linking peptide (CTXI), high-sensitivity C-reactive protein (hs-CRP) and cardiac magnetic resonance (CMR) T 1 mapping value in patients with lone atrial fibrillation (AF). Methods:Fifty-five patients with lone AF in Beijing Anzhen Hospital from July 2017 to June 2018 were prospectively enrolled. Another 20 healthy volunteers were examined at the same time to provide normal reference range. All patients completed PIIINP, CTXI, hs-CRP and CMR examination within one week. CMR examination including cine, pre-contrast T 1 mapping, and late gadolinium enhancement sequences. We used t test, Mann-Whitney U test or chi square test to compare the difference of the above indexes between AF patients and the control group. Spearman correlation analysis was used to determine the associations between left ventricular native T 1 value and blood biomarker in AF patients. Results:All the patients were paroxysmal AF with an average age of (48±10) years, of which 46 (83.6%) were male. The PIIINP, CTXI, hs-CRP, left ventricular native T 1 value of AF patients were 5.83 (3.52, 12.40) ng/ml, 4.63 (3.31, 6.82) μg/ml, 3.41 (1.72, 6.61) mg/L and (1 261±23) ms, respectively, which all significant higher than those in healthy subjects (all P<0.05). The native T 1 value of left ventricular myocardium was positively correlated with PIIINP ( r=0.492, P<0.05) and hs-CRP ( r=0.516, P<0.05), but not with CTXI ( r=0.021, P>0.05). Conclusions:The PIIINP, CTXI and hs-CRP increased in patients with lone AF, PIIINP and hs-CRP were correlated with elevated native T 1 value of left ventricular myocardium.
RESUMEN
Objective: To evaluate the safety and efficacy of catheter ablation in patients with new-onset atrial arrhythmia after surgical excision of left atrial myxoma. Methods: Nine patients with new onset atrial arrhythmia and a prior history of left atrial myxoma, who received surgical myxoma excision and catheter ablation between September 2014 and November 2019, were included in the present study. Baseline characteristics, procedural parameters during catheter ablation, severe perioperative adverse events, recurrence rate of arrhythmia and clinical prognosis were analyzed. Kaplan Meier survival analysis was used to define the maintenance rate of sinus rhythm after catheter ablation in this patient cohort. Results: Nine patients were included. The average age was (55.8 ± 9.1) years old (3 male), there were 3 patients (3/9) with paroxysmal atrial fibrillation (PAF) and 6 patients (6/9) with atrial flutter or atrial tachycardia (AFL or AT). Ablation was successful in all patients, there were no perioperative complications such as stroke, pericardial effusion, cardiac tamponade, vascular complications or massive hemorrhage. During a mean follow-up time of 40.0 (27.5, 55.5) months, sinus rhythm was maintained in six patients (6/9) after the initial catheter ablation. The overall sinus rhythm maintenance rate was 2/3. In addition, 1 out of the 3 AF patients (1/3) developed recurrence of AF at 3 month after ablation, and 2 out of the 6 AFL or AT patients (2/6) developed late recurrence of AF or AFL (19 months and 29 months after ablation), two out of three patients with recurrent AFs or AFL received repeated catheter ablation and one patient remained sinus rhythm post repeat ablation. Meanwhile, there was no recurrence of atrial myxoma, no death, stroke, acute myocardial infarction and other events during the entire follow-up period. Conclusions: Catheter ablation is a safe and feasible therapeutic option for patients with new-onset atrial arrhythmia after surgical excision of left atrial myxoma.
RESUMEN
Objective: To investigate the impact of iron deficiency (ID) on prognosis in heart failure patients with preserved ejection fraction (HFpEF). Methods: A total of 215 consecutive patients with HFpEF, who visited the cardiovascular outpatient department of Beijing Anzhen Hospital, were enrolled in this prospective study. The plasma ferritin level and transferin saturation were measured. Patients were divided into two groups: ID group and non-ID group. ID patients were further divided into absolute ID subgroup and functional ID subgroup. Patients were followed up to 1 year. The endpoints of the study were all-cause mortality and rehospitalization for heart failure (HF). The independent predictors of outcome were determined by Cox regression model. The quality of life of patients was evaluated at the end of the follow-up. Results: The age of this patient cohort was (67±8) years, 39.1% patients were male. The prevalence of ID was 54.4%. Within one year of follow-up, 37 patients (17.2%) died and 70 patients (32.6%) were rehospitalized for HF. Compared to non-ID group, patients in ID group were older, had higher heart rate, lower plasma hemoglobin level and estimated glomerular filtration rate (eGFR) value, had a higher prevalence of anemia and chronic kidney disease (P all<0.05). Kaplan-Meier curves showed that all-cause mortality and rehospitalization for HF in HFpEF patients with ID were higher than patients without ID, and prognosis was similar between patients with absolute ID and functional ID. Multivariable regression analysis showed that ID was an independent predictor for all-cause mortality and rehospitalization for HF in HFpEF patients. The of 6 minutes walking distance was shorter ((356.0±98.3)m vs. (389.2±94.3)m, P=0.023), and the value in Kansas city cardiomyopathy questionnaire was lower ((58.06±10.43) m vs. (61.51±11.64) m, P = 0.039) in patients with ID than patients without ID. Conclusion: In patients with chronic HFpEF, ID is an independent predictor for all-cause mortality and rehospitalization for HF at one year of follow-up, independent of the types of ID.

Objective: This study explored the thromboembolism risk of low-risk atrial fibrillation (AF) patients (CHA2DS2-VASc score of 0 or 1 for male and 1 or 2 for female) with different clinical characteristics to provide the basis for anticoagulation decision-making in these patients. Methods: We prospectively enrolled consecutive 2 862 nonvalvular low-risk AF patients between August 2011 to December 2018 in China-AF (China Atrial Fibrillation Registry) Study, their CHA2DS2-VASc score was 0 or 1 for male and 1 or 2 for female. According to their age, sex, presence or absence of hypertension, diabetes mellitus, congestive heart failure, and vascular disease at the time of enrolling, patients were divided into CHA2DS2-VASc score 0 score group, 1 score group, and 2 score group. Patients were followed up every 6 months by outpatient clinic visit or telephone interview. The outcome was a thromboembolic event, including ischemic stroke and systemic embolism. Univariate Cox regression analysis was used to compare the thromboembolism risk between the patients with different risk factors and CHA2DS2-VASc score 0 group. Results: A total of 2 862 low-risk atrial fibrillation patients were enrolled in this study. 915 patients (32.0%) were female, and age was (55.0±10.7) years old. There were 933 patients (32.6%) in CHA2DS2-VASc score 0 group, 1 401 patients (49.0%) in score 1 group and 528 patients (18.5%) in score 2 group. During follow-up (median 1.5 years, 5 811.82 person-years), 33 cases of thromboembolic events were recorded, the annual rate of thromboembolism was 0.57% (95%CI 0.40%~0.80%). The number of thromboembolic events in patients with CHA2DS2-VASc score 0, 1 and 2 were 8, 11 and 14, respectively, and the annual thromboembolism event rates were 0.40% (95%CI 0.20%-0.81%), 0.39% (95%CI 0.22%-0.71%) and 1.34% (95%CI 0.80%-2.27%), respectively. The risk of thromboembolism of CHA2DS2-VASc score 2 group (HR=3.53, 95%CI 1.48-8.44; P=0.005), especially female patients aged 65-74 years in CHA2DS2-VASc score 2 group (HR=2.67, 95%CI 1.63-4.38; P<0.000) was significantly higher than that in patients of CHA2DS2-VASc score 0 group. Conclusion: Low-Risk Atrial Fibrillation patients with CHA2DS2-VASc score 2, especially female patients aged 65-74 years old with CHA2DS2-VASc score 2 are at higher risk of thromboembolism in low-risk AF patients. For such patients, intensified oral anticoagulant therapy might be helpful to reduce the risk of thrombolism.

Objective To explore the risk factors and prognoses of new-onset atrial fibrillation (NOAF) in patients with acute myocardial infarction (AMI).Methods A total of 468 patients with AMI were admitted into Beijing Anzhen Hospital for emergency pereutaneous coronary intervention (PCI).According to the NOAF occurred during hospitalization,the patients were divided into two groups:the NOAF (n=37) group and the non-NOAF (n=431) group.Parameters including general clinical conditions,coronary lesions,echocardiography,biochemical markers,C-reactive protein (CRP),N-terminal pro-brain natriuretic peptide (NT-pro-BNP),and myocardial markers were collected.In-hospital mortality and incidence of in-hospital main adverse cardiovascular and cerebrovascular events (MACCE) were compared between the two groups.Logistic multivariate regression analyses were performed for the association between the risk factors and NOAF.Results The incidence of NOAF was 7.9% in AMI patients undergoing emergency PCI.There were no significant differences in door-to-balloon time,weight,platelet counts,baseline serum creatinine (SCr),postoperative SCr,triglyceride,total cholesterol,low density lipoprotein cholesterol,high density lipoprotein cholesterol,uric acid,glycosylated hemoglobin A1c,preoperative medication,number of lesions,thrombus aspiration,location of myocardial infarction,and history of hypertension,diabetes,peripheral vascular disease and old myocardial infarction between the two groups.The percentage of women was in the NOAF group (32.4% vs.16.7%,P<0.05) and subjects in this group were significantly elder than those in the non-NOAF groups [(66±10) years vs.(571±11) years,P<0.001].Moreover,the levels of no-reflow rate (40.5% vs.12.6%,P<0.001),CRP [25.2 (15.43,29.97)mg/L vs.5.21 (2.33,16.98) mg/L,P<0.001],white blood cell counts [(11.19±3.44)× 109 vs.(9.91 ±3.23)× 109,p=0.022],NT-pro-BNP [(652.6± 108.8) ng/L vs.(258.3±105.9) ng/L,P<0.001],and troponin I (TnI) [20.41(1.78,87.89) μg/L vs.7.72(1.29,36.39) μg/L,P=0.006] were significantly higher in the NOAF group than in the non-NOAF group,while left ventricular ejection fraction [(47.70± 7.34)% vs.(53.35 ± 8.05)%,P<0.001],and hemoglobin [137.0(125.5,146.0) g/L vs.144.0(133.0,156.0) g/L,P=0.042] were significantly lower in the NOAF group than the non-NOAF group.Patients in the NOAF group had significantly longer hospital stay than those in the non-NOAF group [(8.7± 5.6) d vs.(6.0± 2.3) d,P=0.007].The in-hospital mortality (8.1% vs 1.4% P=0.004) and the incidence of in-hospital MACCE (37.8% vs.7.7%,P<0.001) in the NOAF group were significantly higher than those in the non-NOAF group.Logistic multivariate regression analyses showed that age (HR 1.083,95%CI 1.028-1.141,P=0.003),CRP (HR 1.116,95%CI 1.049-1.187,P=0.001),NT-pro-BNP (HR 1.463,95%CI 1.001-4.064,P=0.001) and no-reflow (HR 4.388,95%CI 1.006-19.144,P=0.049) were independent predictors of NOAF after AMI.Conclusions Age,elevated levels of CRP,NT-pro-BNP,and the absence of no-reflow are risk factors for incident NOAF in patients with AMI in hospital.
RESUMEN
Objective To establish an artificial intelligence deep learning model using clinical colonoscopy images and video to assist the diagnosis by colonoscopy. Methods More than 600000 colonoscopy images were collected in endoscopic center of the Second Affiliated Hospital of Zhejiang University School of Medicine from 2014 to 2018, and endoscopic experts recorded a large number of high-quality operation video of colonoscopy as analysis data. After repeated discussion by six experts, the classified intestinal sites and pathological features were determined, and fuzzy and confusable images were deleted. The final selection result was approximately 1 out of 4. And then the features of images were marked using an independently developed software. The deep learning algorithm was developed using TensorFlow platform of Google. Results After repeated comparison and analysis of the results of machine training and judgment results combined with pathology from endoscopic experts, the sensitivity of the model for some diseases ( such as colon polyps) was 99% under laboratory conditions. In the clinical colonoscopy test, the sensitivity, specificity, and overall accuracy of this model for diagnosis of colon polyps were 98. 30%(4187/4259), 88. 10% (17620/20000), and 92. 92% [2×98. 30%×88. 10%/(98. 30%+88. 10%)], respectively. The sensitivity and specificity for ulcerative colitis were 78. 32% ( 2671/3410) , and 67. 06%(13412/20000), respectively. The diagnosis time spent on a single image was 0. 5±0. 03 s, and it was the real time for application, including system recognition, text prompt in video image, background record and storage. Conclusion The artificial intelligence assisted diagnosis model developed by our team can identify colonic polyps, colorectal cancer, colorectal eminence, colonic diverticulum, ulcerative colitis, etc. The auxiliary diagnosis model of colon disease can guide beginners to carry out colonoscopy, and can improve lesion detection rate, reduce misdiagnosis rate, and improve the overall operating efficiency of endoscopic center, which is conducive to the quality control of colonoscopy.
RESUMEN
Objectives@#This study explored the relationship between weight control and atrial fibrillation (AF) recurrence after catheter ablation in overweight and obese patients.@*Methods@#We prospectively enrolled consecutive 333 overweight and obese patients aged 28 to 87 years old, who underwent catheter ablation for AF in Beijing Anzhen Hospital between October 2015 and February 2016. Data of patients′ characteristics, laboratory examination and treatment were collected at baseline. Each patient was followed up at 3, 6 and 12 months after ablation to collect information on weight, AF recurrence, stroke, major bleeding, hospitalization for cardiovascular reasons and death, etc. Patients were divided into weight controlled group (ΔBMI<-1 kg/m2) and weight uncontrolled group (ΔBMI≥-1 kg/m2), according to the changes in the most recent exposure BMI before AF recurrence in patients with recurrence or the BMI at 12 months′ follow-up in patients without recurrence and the BMI at baseline. Multivariate logistic regression was performed to adjust other known risk factors of AF recurrence and to explore the association between weight control and AF recurrence after catheter ablation.@*Results@#There were 54 patients in weight controlled group and 279 patients in weight uncontrolled group. There were no significant differences in age, gender, education level, left atrial size and history of hypertension between the two groups (all P>0.05). The proportion of patients using angiotensin-converting enzyme inhibitors/angiotensin receptor blockers was higher in the weight controlled group (50.0%(27/54) vs. 34.8%(97/279), P=0.034). However, there was no significant difference in the proportion of patients with obesity (33.3% (18/54) vs. 29.7% (83/279)), paroxysmal AF (59.3% (32/54) vs. 56.6% (158/279)) and AF duration less than 5 years (76.9% (40/52) vs. 65.4% (178/272)) between the weight controlled group and the uncontrolled group. During 1-year follow-up after ablation, the recurrence rate of AF was significantly lower in the weight controlled group than that in the weight uncontrolled group (14.8% (8/54) vs. 32.6%(91/279), P=0.009). Multivariable logistic regression analysis shows that weight control is independently associated with a lower postoperative AF recurrence rate (OR=0.40, 95%CI 0.18-0.90, P=0.026).@*Conclusion@#Weight control is strongly associated with a lower AF recurrence rate after catheter ablation in overweight and obese patients.

RESUMEN
Objective To investigate the influence of body mass index(BMI) on the prognosis of patients who had received elective PCI.Methods The study population consisted of 2964 consecutive patients with electivePCIs performed between July 2009 and September 2011. The patients were divided into three groups based on their preoperative BMI levels:the normal group( BMI<24.0 kg/m2,n=810); the overweight group( 24.0 kg/m2≤BMI<28.0 kg/m2,n=1454) and the obese group(BMI≥28.0 kg/m2,n=700). We examined the association between baseline BMI levels and postoperative mortality through a mean(571.5±130.8)days of follow up.Results Patients with high BMI had a higher percentage of comorbidities compared with the normal BMI group. The results of multivariate Cox regression analysis revealed that preoperative BMI was inversely associated with mortality after adjustment for other factors (HR 0.896,95% CI 0.821-0.977,P=0.031). Compared with the obese group, the hazard ratios for risk of mortality in the overweight and the normal groups were 1.908(95%CI 0.689-5.291,P=0.213) and 2.241(95%CI 1.154-4.350,P=0.017).Conclusions For patients undergoing elective PCI, individuals with obesity and overweight had the better prognosis than those with normal BMI.
