Objective To analyze the causal relationship between obesity and central retinal artery occlusion(CRAO)based on body mass index(BMI),which is commonly used to measure obesity,and Mendelian randomization(MR)method.Methods Two-sample MR analysis was performed using summary statistics from genome-wide associa-tion studies.Exposed genetic tools were divided into the men group(n=60 586,SNP=2 736 876,European men)and women group(n=171 977,SNP=2 494 613,European women);CRAO was selected as the outcome.The instrumental variable for BMI came from the Integrative Epidemiology Unit(IEU)publicly available data;the outcome CRAO data came from the FinnGen database.Inverse variance weighting(IVW)and weighted median(WM)were used to analyze the poten-tial relationship between BMI and CRAO.Results IVW showed that the increased BMI level significantly increased the risk of CRAO in men[OR=4.57,95％CI:1.32-15.82,P=0.016]and the risk of CRAO in women[OR=3.48,95％CI:1.40-8.63,P=0.007].Meanwhile,the WM and MR-Egger analysis results supported the above conclusions.In addition,there was no heterogeneity or pleiotropy in the results of this study.Conclusion The increase in BMI is positively corre-lated with the occurrence of CRAO.This study provides an effective CRAO prevention strategy for asymptomatic patients with elevated BMI levels.

Analysis of refractive prediction errors after flanged intrascleral intraocular lens implantation / 眼科新进展

Flanged intrascleral intraocular lens implantation has become one of the mainstream treatment solutions for aphakia in clinical practice due to its ability to avoid dislocation of the intraocular lens,or subluxation caused by suture degradation or breakage,as well as the ability to eliminate complications such as inflammation or infection caused by su-tures,and the significant improvement in postoperative vision for patients.However,there has been no systematic analysis of the factors that may lead to postoperative refractive prediction errors in China.This article analyzes the possible prob-lems of flanged intrascleral intraocular lens implantation and the reasons for postoperative refractive prediction errors,in order to provide reference for clinical work.

Elevated blood pressure increases risk of proliferative diabetic retinopathy: a Mendelian randomization study / 中华眼底病杂志

Objective:Mendelian randomization (MR) was used to analyze the potential relationship between blood pressure and proliferative diabetic retinopathy (PDR).Methods:Two-sample MR analysis was performed using summary statistics from genome-wide association studies. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were selected as the exposure, PDR as the outcome. The instrumental variable of SBP and DBP came from the publicly available data of the the UK Medical Research Council Comprehensive Epidemiology Unit and Neale Laboratory; the outcome data (8 681 cases in the case group, 204 208 cases in the control group, European population) are from the FinnGen database. Inverse variance weighting (IVW) and weighted median (WM) were used to analyze the potential relationships between SBP, DBP and PDR.Results:MR analysis showed that IVW [SBP: odds ratio ( OR)=1.36, 95% confidence interval ( CI) 1.17-1.57, P= 4.22E-05; DBP: OR=1.29, 95% CI 1.11-1.51, P=8.6E-04], WM (SBP: OR=1.33, 95% CI 1.07-1.66, P=0.009; DBP: OR=1.28, 95% CI=1.03-1.59, P=0.002). The results showed that elevated SBP and DBP increased the risk of PDR. Conclusion:Blood pressure (SBP, DBP) change is positively correlated with the risk of PDR.

A multicenter retrospective cohort study on the attributable risk of patients with Acinetobacter baumannii sterile body fluid infection / 中国感染控制杂志

Objective To investigate the attributable risk(AR)of Acinetobacter baumannii(AB)infection in criti-cally ill patients.Methods A multicenter retrospective cohort study was conducted among adult patients in inten-sive care unit(ICU).Patients with AB isolated from sterile body fluid and confirmed with AB infection in each cen-ter were selected as the infected group.According to the matching criteria that patients should be from the same pe-riod,in the same ICU,as well as with similar APACHE Ⅱ score(±5 points)and primary diagnosis,patients who did not infect with AB were selected as the non-infected group in a 1:2 ratio.The AR was calculated.Results The in-hospital mortality of patients with AB infection in sterile body fluid was 33.3％,and that of non-infected group was 23.1％,with no statistically significant difference between the two groups(P=0.069).The AR was 10.2％(95％CI:-2.3％-22.8％).There is no statistically significant difference in mortality between non-infected pa-tients and infected patients from whose blood,cerebrospinal fluid and other specimen sources AB were isolated(P＞0.05).After infected with AB,critically ill patients with the major diagnosis of pulmonary infection had the high-est AR.There was no statistically significant difference in mortality between patients in the infected and non-infec-ted groups(P＞0.05),or between other diagnostic classifications.Conclusion The prognosis of AB infection in critically ill patients is highly overestimated,but active healthcare-associated infection control for AB in the ICU should still be carried out.

Causality between type 2 diabetes mellitus and age-related macular degeneration: a Mendelian randomization study / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To analyze the causality between type 2 diabetes mellitus(T2DM)and age-related macular degeneration(ARMD)based on two-sample Mendelian randomization(MR).METHODS: T2DM and ARMD samples were extracted from the FinnGen database. Inverse variance weighted(IVW)was used as the main analysis method, MR-Egger and weighted median(WM)as supplementary methods to analyze the potential relationship between them. In addition, Cochran Q test and MR-Egger intercept were also used to analyze the sensitivity, and the P-value was used as the index of research results.RESULTS: IVW showed that T2DM was associated with the incidence of exudative ARMD(OR=1.14, 95%CI 1.01～1.28, P=0.021), but it was not significantly associated with the incidence of atrophic ARMD(OR=0.96, 95%CI 0.86～1.07, P=0.554). The results of sensitivity analysis confirmed that there was no heterogeneity and pleiotropy in this study, and the results were reliable.CONCLUSION: There is a causal relationship between T2DM and exudative ARMD. Considering the high rate of blindness caused by ARMD, it is of great significance to recognize and control the risk factors of ARMD to reduce its prevalence rate and early diagnosis and treatment.

Research on classification method of multimodal magnetic resonance images of Alzheimer's disease based on generalized convolutional neural networks / 生物医学工程学杂志

Alzheimer's disease (AD) is a progressive and irreversible neurodegenerative disease. Neuroimaging based on magnetic resonance imaging (MRI) is one of the most intuitive and reliable methods to perform AD screening and diagnosis. Clinical head MRI detection generates multimodal image data, and to solve the problem of multimodal MRI processing and information fusion, this paper proposes a structural and functional MRI feature extraction and fusion method based on generalized convolutional neural networks (gCNN). The method includes a three-dimensional residual U-shaped network based on hybrid attention mechanism (3D HA-ResUNet) for feature representation and classification for structural MRI, and a U-shaped graph convolutional neural network (U-GCN) for node feature representation and classification of brain functional networks for functional MRI. Based on the fusion of the two types of image features, the optimal feature subset is selected based on discrete binary particle swarm optimization, and the prediction results are output by a machine learning classifier. The validation results of multimodal dataset from the AD Neuroimaging Initiative (ADNI) open-source database show that the proposed models have superior performance in their respective data domains. The gCNN framework combines the advantages of these two models and further improves the performance of the methods using single-modal MRI, improving the classification accuracy and sensitivity by 5.56% and 11.11%, respectively. In conclusion, the gCNN-based multimodal MRI classification method proposed in this paper can provide a technical basis for the auxiliary diagnosis of Alzheimer's disease.

Exploration of the Compensation Mechanism for Public Hospitals Participating in Chronic Disease Management from the Perspective of Medical Prevention Integration / 中国医院管理

Research status and progress of endoplasmic reticulum stress in scleral remodeling / 中华眼底病杂志

The occurrence and development of myopia is closely related to scleral remodeling. Therefore, in order to effectively prevent and cure myopia, it is very important to clarify the mechanism of scleral remodeling. In recent years, Chinese scholars have found that endoplasmic reticulum stress can regulate the expression of apoptotic proteins through the inositol demand protein-1/X box binding protein-1 pathway in the unfolded protein response, thus it is involved in regulating the state of scleral fibroblasts under hypoxia and regulating the occurrence and development of scleral remodeling. At the same time, some studies have found that inhibiting and knocking out protein kinase RNA-like endoplasmic reticulum kinase and activated transcription factor 6 in endoplasmic reticulum stress can effectively inhibit the growth of ocular axis. This proves that endoplasmic reticulum stress plays an important role in the occurrence and development of scleral remodeling. However, the comprehensive analysis of endoplasmic reticulum stress and scleral remodeling has not been reported at home and abroad. In-depth analysis of the relationship between endoplasmic reticulum and scleral remodeling is of great significance for the follow-up analysis and study of the mechanism of scleral remodeling.

Conversion to thoracotomy during minimally invasive esophagectomy: Retrospective analysis in a single center / 中国胸心血管外科临床杂志

@#Objective     To explore the causes of conversion to thoracotomy in patients with minimally invasive esophagectomy (MIE) in a surgical team, and to obtain a deeper understanding of the timing of conversion in MIE. Methods     The clinical data of patients who underwent MIE between September 9, 2011 and February 12, 2022 by a single surgical team in the Department of Thoracic Surgery of the Fourth Hospital of Hebei Medical University were retrospectively analyzed. The main influencing factors and perioperative mortality of patients who converted to thoracotomy in this group were analyzed. Results     In the cohort of 791 consecutive patients with MIE, there were 520 males and 271 females, including 29 patients of multiple esophageal cancer, 156 patients of upper thoracic cancer, 524 patients of middle thoracic cancer, and 82 patients of lower thoracic cancer. And 46 patients were converted to thoracotomy for different causes. The main causes for thoracotomy were advanced stage tumor (26 patients), anesthesia-related factors (5 patients), extensive thoracic adhesions (6 patients), and accidental injury of important structures (8 patients). There was a statistical difference in the distribution of tumor locations between patients who converted to thoracotomy and the MIE patients (P<0.05). The proportion of multiple and upper thoracic cancer in patients who converted to thoracotomy was higher than that in the MIE patients, while the proportion of lower thoracic cancer was lower than that in the MIE patients. The perioperative mortality of the thoracotomy patients was not significantly different from that of the MIE patients (P=1.000). Conclusion     In MIE, advanced-stage tumor, anesthesia-related factors,extensive thoracic adhesions, and accidental injury of important structures are the main causes of conversion to thoracotomy. The rate varies at different tumor locations. Intraoperative conversion to thoracotomy does not affect the perioperative mortality of MIE.

Metabolic profile changes of kidney aging and protective effects of Polygonatum sibiricum polysaccharides on D-galactose-induced aging mice / 数字中医药（英文）

Objective@#To investigate the metabolic trajectory of kidney aging and the effects of Polygonatum sibiricum polysaccharides (PSP) against kidney aging in D-galactose (D-gal)-induced aging mice, based on ultra-performance liquid chromatography/Q-Exactive Orbitrap mass spectrometry (UPLC-Q-Exactive MS/MS). @*Methods@#A total of 36 C57 BL/6J mice were randomly allocated to six groups: control (CON), model (MOD), PSP low-dose (PSP-L), PSP medium-dose (PSP-M), PSP high-dose (PSP-H), and positive drug ascorbic acid (VC) groups. To create models of aging mice, D-gal was intraperitoneally administered to all other groups of mice except the CON group. After modeling, the appropriate Chinese medicine [PSP-L: 150 mg/(kg·d), PSP-M: 300 mg/(kg·d), PSP-H: 600 mg/(kg·d)] or positive drug [ascorbic acid, 300 mg/(kg·d)] was administered for intervention. Key markers of renal function in urine and serum of mice in each group, such as creatinine (Crea), urea nitrogen (BUN), and uric acid (UA) levels, as well as key indicators of oxidative stress in serum and kidney, including superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and glutathione peroxidase (GSH-Px) were determined to validate the successful establishment of kidney aging models and to estimate the effects of PSP. Hematoxylin and eosin (HE), periodic acid Schiff (PAS), and β-galactosidase staining were used to assess the renal pathological changes. The metabolic profiles of serum, kidney, and urine samples from CON, MOD, and PSP-H groups were analyzed by UPLC-Q-Exactive MS/MS, and pattern recognition methods were used to outline the metabolic trajectory of kidney aging and to identify the characteristic metabolites. @*Results@#Age-related alterations in renal histopathology and impaired renal function in mice were also associated with oxidative stress indicators. Following the injection of PSP [PSP-H: 600 mg/(kg·d)], the pathological indices associated with aging were adjusted to normal levels, renal function and oxidative stress were improved in aging mice, and renal pathological damage was markedly improved. Meanwhile, the potential biomarkers were identified by UPLC-Q-Exactive MS/MS analysis and were further analyzed to form related metabolic pathways, with P < 0.05 as a threshold. The results showed that purine, sphingolipid, glycerophospholipid, tryptophan, and riboflavin metabolisms were the main metabolic pathways associated with aging. After administration of PSP, these pathological indices returned to normal levels, and biomarkers related to the aging process, such as adenosine monophosphate (AMP), tryptophan, and 5-hydroxytryptophan, also demonstrated, to some degree, reverse regulation (promoting synthesis). @*Conclusion@#Metabolomics methods based on UPLC-Q-Exactive MS/MS and multivariate statistical analysis can be adopted to establish metabolic profiles in aging mice. PSP has been shown to protect against kidney aging by interfering with the purine, sphingolipid, glycerophospholipid, tryptophan, and riboflavin metabolisms in the kidney.

Cases dead during the postoperative 90 days was 3 in the 31 patients who were admitted from April 2004 to March 2014, versus 0 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( P<0.05). (3) Post-operative pathological examinations. Of the 91 patients, cases with Bismuth type as type Ⅰ?Ⅱ, type Ⅲ, type Ⅳ, cases with T staging as Tis stage, T1 stage, T2a?2b stage, T3 stage, T4 stage, cases with N staging as N0 stage, N1 stage, N2 stage, cases with M staging as M0 stage, M1 stage, cases with TNM staging as 0 stage, Ⅰ stage, Ⅱ stage, Ⅲ stage, ⅣA stage, ⅣB stage, cases with R 0 radical resection, cases with R 1 or R 2 resection were 15, 46, 30, 1, 9, 25, 30, 26, 49, 36, 6, 85, 6, 1, 7, 13, 58, 6, 6, 63, 28. Cases with R 0 radical resection, cases with R 1 or R 2 resection were 15, 16 in the 31 patients who were admitted from April 2004 to March 2014, versus 48, 12 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=9.59, P<0.05). (4) Postoperative prognosis analysis. Of the 91 patients, 3 cases who died within 90 days after surgery were excluded, and the 5-year overall survival rate and median overall survival time of the rest of 88 cases were 44.7% and 55 months. The 5-year overall survival rate was 33.5% in the 28 patients who were admitted from April 2004 to March 2014, versus 50.4% in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=5.31, P<0.05). Results of further analysis showed that the corresponding 5-year overall survival rate of cases without lymph node metastasis was 43.8% in the 16 patients who were admitted from April 2004 to March 2014, versus 61.6% in the 31 patients who were admitted from April 2014 to April 2021. There was a significant difference in the 5-year overall survival rate between these patients without lymph node metastasis ( χ2=3.98, P<0.05). The corresponding 5-year overall survival rate of cases with lymph node metastasis was 18.5% in the 12 patients who were admitted from April 2004 to March 2014, versus 37.7% in the 29 patients who were admitted from April 2014 to April 2021. There was no significant difference in the 5-year overall survival rate between these patients with lymph node metastasis ( χ2=2.25, P>0.05). (5) Influencing factors of postoperative prognosis. Results of multivariate analysis showed that poorly differentiated tumor and R 1 or R 2 resection were inde-pendent risk factors influencing prognosis after surgical treatment of hilar cholangiocarcinoma ( hazard ratio=2.62, 2.71, 95% confidence interval as 1.30?5.29, 1.30?5.69, P<0.05). Conclusions:Compared with traditional surgical diagnosis and treatment, treatment of hilar cholangiocarcinoma based on multidisciplinary diagnosis and treatment can expand surgical indications, reduce proportion of dead patients within 90 days after surgery, improve proportation of radical resection and long-term survival rate. Poorly differentiated tumor and R 1 or R 2 resection are independent risk factors influencing prognosis after surgical treatment of hilar cholangiocarcinoma.

Impacts of nicotine metabolite rate and acupuncture frequency on smoking cessation: a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the efficacy of different acupuncture frequencies in tobacco-dependent patients and explore the impact of nicotine metabolite rate (NMR) on smoking cessation in the intervention with acupuncture.@*METHODS@#A total of 120 cases of tobacco-dependent patients were randomly divided into a high-frequency group (60 cases, 12 cases dropped off) and a low-frequency group (60 cases, 6 cases dropped off). In the two groups, smoking cessation counseling was provided prior to acupuncture. Acupuncture was applied to Baihui (GV 20), Lieque (LU 7), Zusanli (ST 36), etc. Additionally, electric stimulation was added at Lieque (LU 7) and Zusanli (ST 36), with continuous wave, 15 Hz in frequency. The duration of treatment was 8 weeks in either group. In the high-frequency group, the treatment was given 5 times weekly from week 1 to week 4, and was 3 times weekly from week 5 to week 8. In the low-frequency group, the treatment was given 3 times weekly from week 1 to week 4, and was twice a week from week 5 to week 8. The immediate withdrawal rate, persistent withdrawal rate, the score of Fagerstrőm test for nicotine dependence (FTND) before and after treatment, as well as the score of Minnesota nicotine withdrawal scale (MNWS) in 1 and 8 weeks of treatment were compared among the patients with high and low NMR between the two groups separately. The Logistic regression analysis was used to screen the influencing factors of smoking cessation in the intervention with acupuncture.@*RESULTS@#After treatment, there was no statistical significance of the differences in the immediate withdrawal rate (35.4% [17/48] vs 29.6% [16/54]) and the persistent withdrawal rate (33.3% [16/48] vs 25.9% [14/54]) between the high-frequency group and the low-frequency group (P>0.05). The difference in withdrawal rate had no statistical significance between high and low NMR patients (P>0.05). FTND scores after treatment were lower than those before treatment (P<0.01) and MNWS scores were lower than those in 1 week of treatment (P<0.01) in the two groups. However, the differences had no statistical significance between the two groups and between the patients with high NMR and low NMR (P>0.05). Age, education level and NMR were the influencing factors of smoking cessation in the intervention with acupuncture (P<0.05).@*CONCLUSION@#Acupuncture with different frequencies has no obvious impact on the efficacy in tobacco-dependent patients. The lower nicotine metabolite rate in individuals, the better efficacy of acupuncture. The smokers with high nicotine metabolite rate may obtain a better effect of cessation in the high-frequency intervention with acupuncture.

Clinicopathological characteristics and prognostic factors analysis of patients with esopha-geal cancer / 中华消化外科杂志

Objective:To investigate the clinicopathological characteristics and prognostic factors of patients with esophageal cancer.Methods:The retrospective case-control study was conducted. The clinicopathological data of 447 patients with esophageal cancer who were admitted to the Fourth Hospital of Hebei Medical University from January 1, 2017 to December 31, 2020 were collected. There were 312 males and 135 females, aged 60(range, 37?82)years. Observation indica-tors: (1) clinicopathological characteristics; (2) treatment; (3) follow-up; (4) analysis of prognostic factors for esophageal cancer. Follow-up using telephone interview or outpatient examination was conducted to detect survival of patients up to December 2021. The total survival time was from the surgery date to death or the last follow-up. Patients with duration of follow-up more than 2 years were included for survival and prognostic analysis. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were represented as absolute numbers. Kaplan-Meier method was used to draw survival curves and calculate survival rates. Log-Rank test was used for survival analysis. Univariate analysis was conducted using the Log-rank test. Multivariate analysis was conducted using the COX hazard regression model. Results:(1) Clinicopathological characteristics. Of the 447 patients, 69.80%(312/447) were males and 30.20%(135/447) were females, and there were 3, 18, 101, 229, 93, 3 cases aged 30?39 years, 40?49 years, 50?59 years, 60?69 years, 70?79 years, 80?89 years, respectively. About the pathological type, there were 424 cases with squamous carcinoma, 11 cases with small cell carcinoma, 4 cases with adenosquamous carcinoma, 3 cases with sarco-matoid carcinoma, 2 cases with adenocarcinoma, 1 case with neuroendocrine carcinoma, 1 case with undifferentiated carcinoma, and 1 case with adenoid cystic carcinoma. There were 2 cases with tumor located at cervicothoracic segment, 49 cases with tumor located at upper thoracic segment, 273 cases with tumor located at mid-thoracic segment, and 123 cases with tumor located at lower thoracic segment. There were 6, 24, 74, 59, 192, 80, 12 cases in stage pT0, pT1a, pT1b, pT2, pT3, pT4a, pT4b of pathological T staging, respectively. There were 207, 63, 142, 28, 7 cases in stage pN0, pN1, pN2, pN3, pN4 of pathological N staging by Japan Esophagus Society (JES), respectively. There were 207, 128, 76, 36 cases in stage pN0, pN1, pN2, pN3 of pathological N staging by Union for International Cancer Control (UICC), respectively. About TNM staging, there were 25, 53, 127, 174, 68 cases in stage 0, Ⅰ, Ⅱ, Ⅲ, Ⅳa of JES staging, and 16, 9, 53, 35, 108, 96, 45, 85 cases in stage 0, Ⅰa, Ⅰb,Ⅱa, Ⅱb, Ⅲa, Ⅲb, Ⅲc of UICC staging, respectively. (2) Treatment. Of the 447 patients, 63 cases underwent neoadjuvant therapy(12 cases combined with immunotherapy), 384 cases underwent no neoadjuvant therapy. There were 347, 97, 2, 1 cases with surgical approach as right thoracic approach, left thoracotomy approach, cervical abdominal approach, left thoracoabdominal approach, respectively. There were 316, 5, 126 cases with surgical platform as totally endoscopic esophagec-tomy, Hybrid surgery, open surgery, respectively. There were 350 and 97 cases with digestive recons-truction as posterior mediastinal approach and intrathoracic approach, respectively. Surgical margin as R 0, R 1, R 2 resection was detected in 323, 116, 8 cases, respectively. Six of 447 patients died during the hospital stay. (3) Follow-up. All the 447 patients were followed up for 25(range, 2?48)months, including 233 cases with the follow-up more than 2 years. The median survival time of 233 patients was unreached, and the postoperative 2-year survival rate was 76.8%. (4) Analysis of prognostic factors for esophageal cancer. Results of univariate analysis showed that gender, neoadjuvant therapy, surgical margin, pT staging, pN staging by JES, pN staging by UICC, TNM staging by JES, TNM staging by UICC were related factors influencing prognosis of 233 patients with esophageal cancer ( χ2=6.62, 17.81, 32.95, 37.93, 27.06, 35.56, 45.24, 37.84, P<0.05). Results of multivariate analysis showed that gender, surgical margin, TNM staging by JES were independent factors influencing prognosis of 233 patients with esophageal cancer ( hazard ratio=0.48, 1.94, 1.46, 95% confidence intervals as 0.25?0.91, 1.07?3.52, 1.16?1.84, P<0.05). Conclusions:The incidence of esophageal cancer is relatively high in males, with the onset age mainly distribute in 60?69 years and the mainly pathological type as squamous carcinoma. Patients with esophageal cancer have advanced tumor staging, low proportion of neoadjuvant therapy, high R 0 resection rate of surgical treatment. Gender, surgical margin, TNM staging by JES are independent factors influencing prognosis of patients with esophageal cancer.

Clinical analysis of Rotarex percutaneous mechanical thrombectomy for treatment of lower extremity artificial bypass occlusion / 国际外科学杂志

Objective:To evaluate the clinical efficacy of Rotarex percutaneous mechanical thrombectomy(PMT) for treatment of lower extremity arterial graft occlusion.Methods:The clinical data of 19 patients with lower extremity arterial bypass occlusion admitted to our hospital from January 2016 to December 2020 were retrospectively analyzed. All patients were treated with Rotarex-based endovascular therapy. After 12 months follow-up, the clinical features, surgical outcomes and follow-up data were analyzed to identify effectiveness and safety of the therapy. Independent sample t test was used to analyze the measurement data of continuous normal distribution which were expressed as mean±standard deviation( ± s), enumeration data were expressed as number and percentage, and the comparison between groups were analyzed by chi-square test. Results:A technical success rate of 100% was demonstrated. Rotarex combined with catheter directed thrombolysis was performed in 2 cases, Rotarex combined with percutaneous transluminal angioplasty (PTA) was performed in 9 cases. Rotarex combined with stent implantation was performed in 8 patients. The Ankle brachial index significantly increased (0.82±0.14 vs 0.47±0.11, P<0.05). Critical limb ischemia (Rutherford class 4 or higher) improved significantly (0 case vs 9 cases, P<0.05). Distal embolism occurred in 1 patient and acute myocardial infarction occurred in 1 patient. There was no vascular rupture, haemorrhage, infection, pseudoaneurysm, death and amputation. Kaplan-Meier survival analysis revealed 12-month primary patency rate and freedom from clinically driven target lesion revascularization was 78.9% and 89.5% respectively. Conclusion:Rotarex-based endovascular therapy is a safe and effective treatment for graft occlusion after lower extremity arterial prosthesis bypass with high patency rate and few complications.

Type 2 inflammatory responses in atopic dermatitis / 中华皮肤科杂志

Studies have shown that the type 2 inflammatory response and related cytokines such as interleukin-4 and -13, play a key role in atopic dermatitis (AD) . Th2 cells and type 2 cytokines are the core factors in the type 2 inflammatory response, which is mainly involved in the pathogenesis of AD through 3 pathways: aggravating skin barrier defects; activating and strengthening the itching response; pathologically reprograming regulatory T cells into Th2-like regulatory T cells to amplify the type 2 inflammatory response. This review explores the relationship between the type 2 inflammatory response and AD, aiming to help optimize treatment regimens and provide new treatment options for patients with AD.
