Abstract
Objective: To construct an epigenetic clock model for assessing and calibrating human biological age. Methods: Convenience sampling was used to select 186 subjects from the longevity cohort of Guangxi Zhuang Antonornous Region from July 1 to November 30, 2019, and 124 subjects from the physical examination population of the Seventh Medical Center of the PLA General Hospital from October 1 to December 31, 2020. Self-designed questionnaire was applied to collect demographic characteristics and family history of disease. Physical examination was applied to determine heart rate and blood pressure. Fasting peripheral venous blood was drawn for determination of fasting plasma glucose, plasma total cholesterol, triglyceride, plasma high-density lipoprotein cholesterol, plasma low-density lipoprotein cholesterol and telomere length. Methylation levels of EDARADD cg09809672, IPO8 cg19722847, NHLRC1 cg22736354, P2RX6 cg05442902 and SCGN cg06493994 were detected by targeted methylation site sequencing. A total of 54 subjects with unqualified quality control of DNA methylation and telomere length were excluded, and 256 subjects' data were finally analyzed. Trend test was used for the change of methylation level among different ages groups, multiple linear regression method was used to build prediction models of biological age. Kendal rank correlation analysis was used to evaluate the correlation of age gap (Gregorian calendar age minus biological age) with telomere length. Independent sample t-test was used to compare the health-related indicators between subjects with different age gap within different age groups. Results: The M(Q1, Q3)of age of subjects were 67 (51, 91) years old, including 166 females (64.84%). With increase of age, the methylation levels of gene loci were decreased (EDARADD cg09809672, IPO8 cg19722847 and P2RX6 cg05442902) and increased (NHLRC1 cg22736354 and SCGN cg06493994) (all P values<0.05). The established biological age prediction model was as follows: Y=-53.121×EDARADD cg09809672-137.564×IPO8 cg19722847+141.040×NHLRC1 cg22736354-67.893×P2RX6 cg05442902+149.547×SCGNcg06493994+4.592×sex+64.185 (R2=0.86, P<0.001), where Y was the biological age, and the items in the equation were methylation level, sex (male =1, female =2) and intercept in sequence. The Kendall rank correlation coefficient between age gap and telomere length was 0.731 (P<0.001). Compared with the subjects whose age gaP<0, the subjects with age gaP≥0 had higher systolic blood pressure in adolescence [(88.50±8.89) and (109.83±9.48) mmHg, respectively, 1 mmHg=0.133 kPa]; lower TC [(5.48±0.23) and (3.98±0.54) mmol/L, respectively, ] and TG [(3.51±0.32) and (3.41±0.20) mmol/L] in young adults; lower fasting blood glucose in middle age [(6.17±0.67) and (5.37±0.79) mmol/L, respectively, ] and higher diastolic blood pressure in nonagenarian age [(76.99±6.78) and (83.97±9.36) mmHg, respectively, ] (all P values<0.05). Conclusion: The constructed epigenetic clock model can be used to evaluate and calibrate human biological age.

Abstract
PURPOSE The magnetic compression technique (MCT) is a new surgical method that has been used for gastrointestinal anastomosis, choledochojejunostomy, and intestinal anastomosis, but there are no reports on its use for esophagogastric anastomosis. This study aimed to investigate the feasibility of using MCT to fashion esophagogastric anastomoses in rabbits. METHODS Twenty rabbits were randomized into an MCT group (study group, n = 10) and a hand-sewn group (control group, n = 10). The magnetic compression anastomosis device used in this study was made of neodymium iron boron (NdFeB) and possessed parent (PMR) and daughter (DMR) magnetic rings. To fashion the anastomosis, the PMR and DMR were inserted into the lower esophagus and gastric fundus, respectively. The coupled magnets automatically compressed the sandwiched tissues and were expelled once the anastomosis was installed. The two groups were further compared in terms of the anastomosis construction time, survival rate, and postoperative complications. One month after the anastomosis was installed, the burst pressure and gross appearance of the anastomoses were evaluated. RESULTS The anastomosis construction time in the study group was significantly shorter than that in the control group (10.50 ± 1.58 min vs. 18.60 ± 2.22 min; P < 0.05), and the magnetic rings were defecated out in 10.70 ± 3.49 days. The incidence of anastomotic blockage in both the study and control groups did not differ significantly (0%, 0/10 vs. 20%, 2/10; P > 0.05). Anastomotic leakage was not found in either of the groups, and the anastomoses burst pressures were similar in the two groups. However, the magnetically compressed anastomoses in the study group had a relatively smoother gross appearance than the hand-sewn anastomoses. CONCLUSION The magnetic compression anastomosis device is a safe and feasible tool for fashioning esophagogastric anastomoses in this animal model.

Abstract
Based on the principle of magnetic anastomosis technique, the design of magnetic anastomosis system for endoscopic tissue clamping is proposed. The system includes a semi-ring magnet, a special structure transparent cap and a detachable push rod. With the help of the existing digestive endoscopy and endoscopic tissue gripper, the endoscopic close clamping and anastomosis of the bleeding or perforated tissue can be completed. After the anastomosis, the magnet falls off and is discharged through the digestive tract. Animal experiments showed that the system was easy to use, the fistula was clamped firmly, the magnet was discharged for 7~21 days, and there was no magnet retention and digestive tract obstruction. Further safety verification, optimization of endoscopic operation, the system can be used in clinical trial.

Abstract
Objective: To conduct a randomized controlled clinical trial to evaluate the clinical efficacy and prognostic value of Jinhua Qinggan granules in patients with confirmed and suspected coronavirus disease 2019 (COVID-19). Methods: A total of 123 suspected and confirmed COVID-19 patients participated in this clinical trial and were randomly divided into Jinhua and Western medicine groups. For 14 days, the Jinhua group was treated with Jinhua Qinggan granules and antiviral drugs, and the Western medicine group was treated with antiviral drugs alone. We collected information on clinical symptoms, disease aggravation rates, and negative conversion rates of nucleic acids in patients, and observed the effects of anti-infective drugs. Results: There was no significant difference in symptom improvement rates between the two groups, both confirmed and suspected patients (P > 0.05). Both treatments relieved symptoms such as fever, fatigue, and diarrhea. However, the Jinhua treatment was superior in relieving fever and poor appetite. Anti-infective drug use rates were significantly lower in the Jinhua group than in the control group. Conclusion: Jinhua Qinggan granules combined with Western medicine could relieve the clinical symptoms of fever and poor appetite in COVID-19 patients, reduce the use of antibiotics to a certain extent. Clinical Trial Registration: The registration number at China Clinical Trial Registry is ChiCTR2000029601.

Abstract
Purpose Percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) are two revascularization strategies for patients with coronary artery disease (CAD) and left ventricular dysfunction. However, the comparisons of effectiveness between the two strategies are insufficient. This study is aimed to compare the effectiveness between PCI and CABG among patients with moderate left ventricular dysfunction. Patients and Methods A total of 1487 CAD patients with moderate reduced ejection fraction (36%≤EF≤40%), who underwent either PCI or CABG, were enrolled in a real-world cohort study (No. ChiCTR2100044378). Clinical outcomes included short- and long-term all-cause mortality, rates of heart failure (HF) hospitalization and repeat revascularization. Propensity score matching was used to balance the two cohorts. Results PCI was associated with lower 30-day mortality rate (hazard ratio [HR] [95% CI], 0.35 [0.15–0.83]; P=0.02). At a mean follow-up of 4.5 years, PCI and CABG had similar all-cause death (HR [95% CI], 0.82 [0.56–1.20]; P=0.30) and heart failure (HF) hospitalization (HR [95% CI], 0.93 [0.54–1.60]; P=0.79), but PCI had higher risk of repeat revascularization (HR [95% CI], 8.62 [3.67–20.23]; P<0.001). Improvement in EF measured at 3 months later after revascularization was also similar between PCI and CABG (P for interaction=0.87). Conclusion CAD patients with moderate reduced EF who had PCI had lower short-term mortality rate but higher risk of repeat revascularization during follow-up than patients who had CABG. PCI showed comparable long-term survival, HF hospitalization risk, and EF improvement.

Abstract
BACKGROUND Graft-versus-host disease (GVHD) following liver transplantation (LT) is an unpredictable complication with poor outcome. However, consensus regarding the diagnosis and therapeutic regimen for the disease is yet lacking. The present study summarized the clinical experience on the diagnosis and treatment of acute GVHD (aGVHD) following LT and reviewed the pertinent literature.
CASE SUMMARY Between January 1st, 2000 and December 31st, 2020, a total of 1053 LT were performed in the First Affiliated Hospital of Xi’an Jiaotong University. Six recipients developed aGVHD with clinical symptoms of fever, rash, diarrhea, and pancytopenia. The incidence of aGVHD was 0.57%. The median time from LT to the clinical presentation of aGVHD was 22.17 d. The median time from the beginning of the clinical symptom to histopathological diagnosis was 7.5 d. All six cases underwent treatment of immunosuppressant adjustment, corticosteroids, human normal immunoglobulin, and antithymocyte globulin/IL-2 antagonists. Despite intensive treatment strategies, 4 patients were deceased due to sepsis, multiple organ failure, and cerebral hemorrhage. The remaining two cases were discharged as treatment successfully. However, one died because of tuberculosis infection on the 6th month of follow-up, the other one was alive healthy during 30 mo of follow-up.
CONCLUSION The rapid diagnosis of aGVHD is mainly based on the time from the first symptom, histopathological features, and the donor T-lymphocyte chimerism. Our cases report highlights massive corticosteroid therapy and age difference between donors and recipients could accelerate to aGVHD. Moreover, gut microbial interventions and donor-targeted serotherapy may provide novel therapeutics.

Abstract
Objectives: To investigate the association between diabetes mellitus (DM) and ejection fraction (EF) improvement following revascularization in patients with coronary artery disease (CAD) and left ventricular (LV) dysfunction. Background: Revascularization may improve outcomes of patients with LV dysfunction by improvement of EF. However, the determinants of EF improvement have not yet been investigated comprehensively. Method: A cohort study (No. ChiCTR2100044378) of patient with repeated EF measurements after revascularization was performed. All patients had baseline EF ≤40%. Patients who had EF reassessment 3 months after revascularization were enrolled. Patients were categorized into EF unimproved (absolute increase in EF ≤5%) and improved group (absolute increase in EF >5%). Results: A total of 974 patients were identified. 573 (58.8%) had EF improved. Patients with DM had greater odds of being in the improved group (odds ratio [OR], 1.42; 95% CI, 1.07–1.89; P = 0.014). 333 (34.2%) patients with DM had a greater extent of EF improvement after revascularization (10.5 ± 10.4 vs. 8.1 ± 11.2%; P = 0.002) compared with non-diabetic patients. The median follow-up time was 3.5 years. DM was associated with higher risk of overall mortality (hazard ratio [HR], 1.46; 95% CI, 1.02–2.08; P = 0.037). However, in EF improved group, the risk was similar between diabetic and non-diabetic patients (HR, 1.36; 95% CI, 0.80–2.32; P = 0.257). Conclusions: Among patients with reduced EF, DM was associated with greater EF improvement after revascularization. Revascularization in diabetic patients might partially attenuate the impact of DM on adverse outcomes. Our findings imply the indication for revascularization in patients with LV dysfunction who present with DM.

Co-exposure to fluoride and arsenic disrupts intestinal flora balance and induces testicular autophagy in offspring rats. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2021; 222:112506.

Abstract
While numerous studies have shown that fluoride or arsenic exposure may damage the reproductive system, there are few reports of co-exposure to fluoride and arsenic. In addition, the literature on autophagy and intestinal flora composition in reproductive toxicity studies of co-exposure to fluoride and arsenic is insufficient. In this study, we developed a rat model of fluoride and arsenic exposure via drinking water from pre-pregnancy to 90 days postnatal. Sprague-Dawley rats were randomly divided into sterile water control group, fluoride group (100 mg/L NaF), arsenic group (50 mg/L NaAsO2) and combined exposure group (100 mg/L NaF+50 mg/L NaAsO2). Our results showed that fluoride and arsenic exposure caused a reduction in testicular weight and significant pathological damage to tissue. We found that the levels of follicle-stimulating hormone, luteinizing hormone, and testosterone were reduced to varying degrees. Meanwhile experiments showed that fluoride and arsenic exposure can modulate autophagic flux, causing increased levels of Beclin1 and LC3 expression and decreased p62 expression. Analogously, by performing 16S sequencing of rat feces, we found 24 enterobacterial genera that differed significantly among the groups. Furthermore, the flora associated with testicular injury were identified by correlation analysis of hormonal indices and autophagy alterations with intestinal flora composition at the genus level, respectively. In summary, our study shows that fluoride and arsenic co-exposure alters autophagic flux in the testis, causes testicular injury, and reveals an association between altered intestinal flora composition and testicular injury.

Abstract
Objective: To identify whether splenectomy for treatment of hypersplenism has any impact on development of hepatocellular carcinoma(HCC) among patients with liver cirrhosis and hepatitis. Methods: Patients who underwent splenectomy for hypersplenism secondary to liver cirrhosis and portal hypertension between January 2008 and December 2012 were included from seven hospitals in China, whereas patients receiving medication treatments for liver cirrhosis and portal hypertension (non-splenectomy) at the same time period among the seven hospitals were included as control groups. In the splenectomy group, all the patients received open or laparoscopic splenectomy with or without pericardial devascularization. In contrast, patients in the control group were treated conservatively for liver cirrhosis and portal hypertension with medicines (non-splenectomy) with no invasive treatments, such as transjugular intrahepatic portosystemic shunt, splenectomy or liver transplantation before HCC development. All the patients were routinely screened for HCC development with abdominal ultrasound, liver function and alpha-fetoprotein every 3 to 6 months. To minimize the selection bias, propensity score matching (PSM) was used to match the baseline data of patients among splenectomy versus non-splenectomy groups. The Kaplan-Meier method was used to calculate the overall survival and cumulative incidence of HCC development, and the Log-rank test was used to compare the survival or disease rates between the two groups. Univariate and Cox proportional hazard regression models were used to analyze the potential risk factors associated with development of HCC. Results: A total of 871 patients with liver cirrhosis and hypertension were included synchronously from 7 tertiary hospitals. Among them, 407 patients had a history of splenectomy for hypersplenism (splenectomy group), whereas 464 patients who received medical treatment but not splenectomy (non-splenectomy group). After PSM,233 pairs of patients were matched in adjusted cohorts. The cumulative incidence of HCC diagnosis at 1,3,5 and 7 years were 1%,6%,7% and 15% in the splenectomy group, which was significantly lower than 1%,6%,15% and 23% in the non-splenectomy group (HR=0.53,95%CI:0.31 to 0.91,P=0.028). On multivariable analysis, splenectomy was independently associated with decreased risk of HCC development (HR=0.55,95%CI:0.32 to 0.95,P=0.031). The cumulative survival rates of all the patients at 1,3,5,and 7 years were 100%,97%,91%,86% in the splenectomy group,which was similar with that of 100%,97%,92%,84% in the non-splenectomy group (P=0.899). In total,49 patients (12.0%) among splenectomy group and 75 patients (16.2%) in non-splenectomy group developed HCC during the study period, respectively. Compared to patients in non-splenectomy group, patients who developed HCC after splenectomy were unlikely to receive curative resection for HCC (12.2% vs. 33.3%,χ²=7.029, P=0.008). Conclusion: Splenectomy for treatment of hypersplenism may decrease the risk of HCC development among patients with liver cirrhosis and portal hypertension.

Abstract
Objective: To analyze the clinical characteristics of chronic total coronary occlusion (CTO) combined with bifurcation lesions and the features of coronary intervention and perioperative complications. Methods: This study adopted retrospective cross-sectional research methods and included 673 patients who underwent interventional therapy for chronic total occlusion in Beijing Anzhen Hospital. According to whether there were side branches (diameter ≥2 mm) within 5 mm before and after the CTO occlusion segment, patients were divided into bifurcation group (337 cases) and non-bifurcation group (336 cases). The measurement data did not conform to the normal distribution and were represented as M (Q1, Q3). The clinical risk factors, coronary angiography characteristics, interventional treatment strategies and perioperative complications were compared between the two groups. Results: The patients in the bifurcation group were 60 (51, 65) years old, and 86.6% (292 cases) were male; the patients in the non-bifurcation group were 60 (52, 66) years old, and 83.0% (279 cases) were male.Coronary artery disease in all patients was mainly multivessel disease, of which three-vessel disease accounted for 59.9% (403 cases) and double-vessel disease accounted for 25.4% (171 cases).The target vessel in the bifurcation group was predominantly left anterior descending artery (62.3%, 210 cases), and the target vessel in the non-bifurcation group was more common in the right coronary artery (56%, 188 cases). The target vessel diameter was larger in the bifurcation group (2.91(2.71, 3.24) mm vs 2.80(2.55, 3.13) mm, P<0.001). Most patients used the antegrade technique (88%, 592 cases), and the use of antegrade technique in the bifurcation group (91.9%, 307 cases) was higher than that in the non-bifurcation group (84.8%, 285 cases) (P=0.012). After CTO-PCI, 72.8% (490 cases) of patients achieved successful angiography. A total of 73 patients (10.8%) had perioperative complications, and there was no statistical difference between the two groups. However, the incidence of perioperative myocardial infarction was higher in the bifurcation group (5.9%, 20 cases) than non-bifurcation group (2.7%, 9 cases) (P=0.038). Conclusions: CTO complicated with bifurcation lesions are very common in clinical practice. Most patients with CTO have multiple coronary artery disease at the same time. The target vessel is more common in the left anterior descending artery, and the diameter of the vessel is larger. It is more common to use antergrade technique, accompanied by more perioperative myocardial infarctions.

Abstract
Objective: To determine the potential risk factors of delayed hemorrhage after endoscopic submucosal dissection (ESD) in patients with early gastric carcinomas or precancerous lesions. Methods: The clinical data of 637 patients with early gastric carcinomas (EGC) who treated with ESD in Department of Endoscopy at Cancer Hospital, Chinese Academy of Medical Sciences, from August 2013 to August 2019, were retrospectively analyzed. Univariate analysis and multivariate logistic analysis were conducted to evaluate the risk factors associated with delayed bleeding. Results: A total of 699 lesions in 637 patients, of which 696 lesions were resected enbloc, the curative resection rate was 92.1% (644/699). The pathological diagnosis after ESD showed that 46 cases were low-grade intraepithelial neoplasia, 71 were high-grade intraepithelial neoplasia, and 582 were cancer. Delayed bleeding occurred in 74 lesions, while other 625 lesions without postoperative bleeding. The incidence was 10.6%. Compared with the non-bleeding group, there were statistically significant differences in the maximum length of the lesion, the gross shape of the lesion, the control of intra operative bleeding, and the operation time in the delayed bleeding group (P<0.05). Multivariate logistic regression analysis showed that the maximum length of the lesion and the gross shape of the lesion were independent factors of delayed bleeding after ESD. Delayed bleeding was inclined to occur in patients with lesion size ≥3.0 cm (OR=1.958, 95% CI: 1.162-3.299) and the superficial and flat lesion (OR=10.598, 95% CI: 1.313-85.532) after ESD. Conclusions: The maximum length of the lesion and the gross shape of the lesion are independent impact factors of delayed bleeding occurring in patients with EGC and precancerous lesions after ESD. Patients with lesion size≥3 cm, or superficial flat lesion should be paid attention after ESD operation. It needs to take timely measures to prevent the very likely bleeding in order to ensure postoperative recovery and improve the quality of life for postoperative patients.

Abstract
Objectives: To explore the short and long term outcomes of coronary artery disease(CAD) patients with heart failure with reduced ejection fraction (HFrEF) after two different revascularization strategies. Methods: The CAD patients with HFrEF who had undegone successful revascularization from January 1, 2005 to December 31, 2014 in Anzhen Hospital were analyzed based on registries. The baseline characteristics, changes of left heart function and the MACCE after a mean follow-up of 3.1 years were compared. Results: A total of 1 813 CAD patients with HFrEF who had undergone successful PCI (n=687) or CABG (n=1 126) satisfied the inclusion criteria were included. The age of all patients included was (59.6±10.0) years and male patients accounted for 83.1%. For the coronary angiographic features, the CABG group showed higher SYNTAX score (27.3±10.2 vs 31.1±10.4, P<0.01) and greater left ventricular end diastolic diameter (LVEDD) [(59.8±7.2) vs (57.9±7.7)mm, P<0.001]. The LVEF before revascularization was similar in PCI and CABG group [(35.8±5.1)% vs (35.9±4.6)%, P>0.05]. At three-month, one-year or three-year follow-up after revascularization, the improvement of LVEF was similar in the two groups (P>0.05). After multivariable adjustment, three-year outcomes revealed that the risks of all-cause mortality and cardiac death were not statistically significant between CABG and PCI group (16.3% vs 14.3%, HR=1.5, 95%CI: 1.2-2.1, P=0.07; 8.5% vs 8.2%, HR=1.3, 95%CI: 1.1-1.4, P=0.20). With regards to other endpoints, CABG group had a higher rate of stroke (6.2% vs 2.9%, HR=2.9, 95%CI:2.3-3.6, P<0.01) but a lower rate of repeat revascularization (6.5% vs 15.1%, HR=0.5, 95%CI:0.3-0.7, P<0.01) compared to PCI group. And for patients with SYNTAX score≥33, PCI group showed a comparable risk of all-cause mortality or cardiac death (HR=0.8, 95%CI: 0.4-1.3, P=0.06; HR=0.7, 95%CI:0.4-1.0, P=0.90). Conclusions: In CAD patients with HFrEF who had undergone successful revascularization, PCI is not inferior to CABG for long-term survival. PCI should be taken into consideration to become an alternative strategy in patients with left ventricular dysfunction.

Abstract
Abstract
Objectives
Zeaxanthin, an oxygenized carotenoid, exerts antioxidant properties in human nutrition and metabolism. Likely other carotenoids, zeaxanthin is poorly absorbed in the small intestine. The large portion of zeaxanthin reaches the colon and is not fully recovered in the colon. In this study, we aimed to investigate the association of zeaxanthin intake with the gut microbiome homeostasis and metabolomic responses in mice.
Methods
Six-week-old male and female C57BL/6J wild type (WT), beta-carotene oxygenase 2 (BCO2) knockout mice were fed with AIN93M chow diets supplemented with or without zeaxanthin (0.02% w/w) for 10 weeks. At the termination of the study, mice were fasted for 3 hrs prior to euthanization. Cecal contents, colon, serum, feces, and other tissues were collected for laboratory assessments.16S rRNA sequencing and LC-MS/MS were performed for gut microbiota profiling and serum and fecal metabolomics analysis, respectively.
Results
Significant zeaxanthin accumulation occurred in BCO2 KO, but not WT mice. Zeaxanthin accumulation was associated with the alteration of colonic gut microbiota composition, for example, zeaxanthin-increased abundance in Lachnospiraceae, Proteobacteria, and Parabacteroides, indicating enhanced short-chain production, improved intestinal integrity, and anaerobic bacterial colonization. The results of fecal and serum metabolomics revealed that zeaxanthin significantly altered tyrosine metabolism, branched-chain fatty acid oxidation, fatty acid biosynthesis, and phospholipid biosynthesis, and suppressed levels of kynurenine and trimethylamine N-oxide (TMAO).
Conclusions
The results suggested that zeaxanthin accumulation promotes gut microbiome homeostasis and alters the gut microbial metabolites as signals in stimulating the host-gut microbe interplay.

Abstract
AIMS To compare the risk of phlebitis between midline catheters and peripherally inserted central catheters in infusion therapy with a meta-analysis. DESIGN This was a systematic literature review and meta-analysis. DATA SOURCES Web of Science, PubMed, Scopus, Embase, Cochrane Library, ProQuest, CNKI, WanFang, VIP and SinoMed were searched from inception to May 2020. REVIEW METHODS All studies comparing the risk of phlebitis between midline catheters and peripherally inserted central catheters were included. According to the inclusion and exclusion criteria, two authors independently assessed the literature and extracted the data. Meta-analyses were conducted to generate estimates of phlebitis risk in patients with midline catheters verse peripherally inserted central catheters, and publication bias was evaluated with RevMan 5.3. RESULTS A total of seven studies were collected, involving 1377 participants. The incidence of phlebitis with midline catheters and peripherally inserted central catheters was 1.52% and 3.41%. Meta-analysis showed that the incidence of phlebitis has no significant difference between midline catheters and peripherally inserted central catheters. The sensitivity analysis shows that the results from this meta-analysis are fair in overall studies. All studies have no significant publication bias. CONCLUSION This study provides the first systematic assessment of the risk of phlebitis between midline catheters and peripherally inserted central catheters. The incidence of phlebitis has no significant difference between them. There are many factors to consider when choosing vascular access devices.
