Abstract
Diabetic kidney disease (DKD) can lead to end-stage kidney disease (ESKD) and mortality; however, few mechanistic biomarkers are available for high-risk patients, especially those without macroalbuminuria. Urine from participants with diabetes from the Chronic Renal Insufficiency Cohort (CRIC) study, the Singapore Study of Macro-angiopathy and Micro-vascular Reactivity in Type 2 Diabetes (SMART2D), and the American Indian Study determined whether urine adenine/creatinine ratio (UAdCR) could be a mechanistic biomarker for ESKD. ESKD and mortality were associated with the highest UAdCR tertile in the CRIC study and SMART2D. ESKD was associated with the highest UAdCR tertile in patients without macroalbuminuria in the CRIC study, SMART2D, and the American Indian study. Empagliflozin lowered UAdCR in nonmacroalbuminuric participants. Spatial metabolomics localized adenine to kidney pathology, and single-cell transcriptomics identified ribonucleoprotein biogenesis as a top pathway in proximal tubules of patients without macroalbuminuria, implicating mTOR. Adenine stimulated matrix in tubular cells via mTOR and stimulated mTOR in mouse kidneys. A specific inhibitor of adenine production was found to reduce kidney hypertrophy and kidney injury in diabetic mice. We propose that endogenous adenine may be a causative factor in DKD.

Abstract
Objective: To study the infection status and epidemiological characteristics of parainfluenza virus (PIV) in acute respiratory tract infection adult cases in Shanghai from 2015 to 2021, and to provide a scientific basis for preventing and controlling PIV. Methods: Acute respiratory tract infections were collected from 13 hospitals in Shanghai from 2015 to 2021. Relevant information was registered, and respiratory specimens were sampled to detect respiratory pathogens by multiplex PCR. Results: A total of 5 104 adult acute respiratory tract infection cases were included; the overall positive rate of the respiratory pathogens was 29.37% (1 499/5 104). The positive rate of PIV was 2.61% (133/5 104), compared with 2.32% (55/2 369) and 2.85% (78/2 735) in influenza-like cases (ILI) and severe acute respiratory infection (SARI) cases, respectively. Among them, PIV3 accounted for the highest proportion (62.41%, 83/133), followed by PIV1 (18.80%, 25/133), PIV2 (9.77%, 13/133), and PIV4 (9.02%, 12/133). The incidence of PIV-positive cases was mainly distributed in the first and second quarters, accounting for 62.41% (83/133). The difference in the incidence in each quarter was significant (χ2=24.78, P<0.001). Mixed infection accounted for 18.80% (25/133) of 133 PIV-positive cases, the mixed infection rates of ILI and SARI were 18.18% (10/55) and 19.23% (15/78), respectively, and the main mixed pathogen of PIV was coronavirus 229E. Conclusions: There are a certain proportion of PIV-positive acute respiratory tract infection cases in Shanghai. It is necessary to strengthen the etiological surveillance in acute respiratory tract infection cases, especially the mixed infection of PIV and other pathogens.

Abstract
To investigate the relationship between male semen parameters and sperm DNA fragment index with age. Adopt cross-sectional sampling survey design, 3 203 male patients who visited the Department of Reproductive Andrology in the Third Affiliated Hospital of Zhengzhou University from January 2019 to June 2021 were selected as subjects. Age range is 18-57 years, with the median age of 30 years. Through quartile regression analysis, the correlation between age and different male semen parameters and DNA fragment index (DFI) was presented. The study population was divided into ≤30 years old group and >30 years old group, and the correlation between age and semen volume, sperm concentration, total sperm count, progressive motility, total motility, percentage of normal sperm and DFI level were compared and analyzed. The results showed that there were significant differences in progressive motility, total motility and DFI level among different age groups (χ2=-4.608, -4.604, -7.719,P all <0.05), but there was no significant difference in semen volume, sperm concentration, total sperm count and percentage of normal sperm (χ2=-1.712, -1.203, -0.149, -0.175,P all >0.05). In the>30 years old age group, there was a very weak negative correlation between male age and semen volume, progressive motility and total motility (r=-0.137, -0.101 and -0.056, P all <0.05). There was a very weak positive correlation between male age and sperm concentration and sperm DFI level (r=0.061, 0.190, P all <0.05), while there was no correlation between male age and total sperm count and percentage of normal sperm (r=-0.018, -0.016,P all >0.05). In conclusion, with the increase of age, especially after the age of 30, semen volume, progressive motility and total motility decreased, while sperm concentration and DFI level increased, and semen quality decreased.

Abstract
BACKGROUND Gastric cancer (GC) is one of the most common malignant tumors with poor prognosis in terms of advanced stage. However, the survival-associated biomarkers for GC remains unclear. AIM To investigate the potential biomarkers of the prognosis of patients with GC, so as to provide new methods and strategies for the treatment of GC. METHODS RNA sequencing data from The Cancer Genome Atlas (TCGA) database of STAD tumors, and microarray data from Gene Expression Omnibus (GEO) database (GSE19826, GSE79973 and GSE29998) were obtained. The differentially expressed genes (DEGs) between GC patients and health people were picked out using R software (x64 4.1.3). The intersections were underwent between the above obtained co-expression of differential genes (co-DEGs) and the DEGs of GC from Gene Expression Profiling Interactive Analysis database, and Gene Ontology (GO) analysis, Kyoto Encyclopedia of Gene and Genome (KEGG) pathway analysis, Gene Set Enrichment Analysis (GSEA), Protein-protein Interaction (PPI) analysis and Kaplan-Meier Plotter survival analysis were performed on these DEGs. Using Immunohistochemistry (IHC) database of Human Protein Atlas (HPA), we verified the candidate Hub genes. RESULTS With DEGs analysis, there were 334 co-DEGs, including 133 up-regulated genes and 201 down-regulated genes. GO enrichment analysis showed that the co-DEGs were involved in biological process, cell composition and molecular function pathways. KEGG enrichment analysis suggested the co-DEGs pathways were mainly enriched in ECM-receptor interaction, protein digestion and absorption pathways, etc. GSEA pathway analysis showed that co-DEGs mainly concentrated in cell cycle progression, mitotic cell cycle and cell cycle pathways, etc. PPI analysis showed 84 nodes and 654 edges for the co-DEGs. The survival analysis illustrated 11 Hub genes with notable significance for prognosis of patients were screened. Furtherly, using IHC database of HPA, we confirmed the above candidate Hub genes, and 10 Hub genes that associated with prognosis of GC were identified, namely BGN, CEP55, COL1A2, COL4A1, FZD2, MAOA, PDGFRB, SPARC, TIMP1 and VCAN. CONCLUSION The 10 Hub genes may be the potential biomarkers for predicting the prognosis of GC, which can provide new strategies and methods for the diagnosis and treatment of GC.

ESKD and mortality were associated with the highest UAdCR tertile in CRIC (HR 1.57, 1.18, 2.10) and SMART2D (HR 1.77, 1.00, 3.12). ESKD was associated with the highest UAdCR tertile in patients without macroalbuminuria in CRIC (HR 2.36, 1.26, 4.39), SMART2D (HR 2.39, 1.08, 5.29), and Pima Indian study (HR 4.57, CI 1.37-13.34). Empagliflozin lowered UAdCR in non-macroalbuminuric participants. Spatial metabolomics localized adenine to kidney pathology and transcriptomics identified ribonucleoprotein biogenesis as a top pathway in proximal tubules of patients without macroalbuminuria, implicating mammalian target of rapamycin (mTOR). Adenine stimulated matrix in tubular cells via mTOR and stimulated mTOR in mouse kidneys.

Physical exercise attenuates age-related muscle atrophy and exhibits anti-ageing effects via the adiponectin receptor 1 signalling. J Cachexia Sarcopenia Muscle 2023.

Abstract
BACKGROUND Although the adiponectin signalling exerts exercise-mimicking effects, whether this pathway contributes to the anti-ageing benefits of physical exercise has not been established yet. METHODS Swim exercise training and wheel running were used to measure lifespan in the nematode Caenorhabditis elegans and skeletal muscle quality in mice, respectively. Muscle weight, muscle fibre cross-sectional area (CSA) and myonuclei number were used to evaluate muscle mass. RNA sequencing (RNA-Seq) analysis of skeletal muscle in exercised mice was used to study the underlying mechanisms. Western blot and immunofluorescence were performed to explore autophagy- and senescence-related markers. RESULTS The C. elegans adiponectin receptor PAQR-1/AdipoR1, but not PAQR-2/AdipoR2, was activated (3.55-fold and 3.48-fold increases in p-AMPK on Days 1 and 6, respectively, P < 0.001), which was involved in lifespan extension in exercised worms. Exercise training increased skeletal muscle mass index (1.29-fold, P < 0.01), muscle weight (1.75-fold, P < 0.001), myonuclei number (1.33-fold, P < 0.05), muscle fibre CSA (1.39-fold, P < 0.05) and capillary abundance (2.19-fold, P < 0.001 for capillary density; 1.58-fold, P < 0.01 for capillary number) in aged mice. Physical exercise reduced protein (2.94-fold, P < 0.001) and mRNA levels (1.70-fold, P < 0.001) of p16INK4a , a marker for cellular senescence, in skeletal muscle of aged mice. These beneficial effects of exercise on skeletal muscle of mice were dependent on AdipoR1. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis for differentially expressed genes in skeletal muscle between exercised mice with and without AdipoR1 knockdown by RNA-Seq analysis revealed that several KEGG pathways, such as 'AMPK signalling pathway' (P < 0.001), 'FOXO signalling pathway' (P < 0.001) and 'autophagy' (P < 0.001) were overrepresented. Knockdown of FoxO3a inhibited exercise-mediated beneficial effects on skeletal muscle quality of mice by inhibiting autophagy/mitophagy (3.81-fold reduction in LC3-II protein, P < 0.001; 1.53-fold reduction in BNIP3 protein, P < 0.05). Knockdown of daf-16, the FoxO homologue in C. elegans, reduced autophagy (2.77-fold and 2.06-fold reduction in GFP::LGG-1 puncta in seam cells and the intestine, respectively, P < 0.05) and blocked lifespan extension by exercise in worms. CONCLUSIONS Our findings provide insights into how the AdipoR1 pathway has an impact on the anti-ageing benefits of exercise and implicate that activation of the AdipoR1 signalling may represent a potential therapeutic strategy for reducing age-related loss of skeletal muscle.

Abstract
Hexane is a widely used organic solvent in industry, and chronic hexane poisoning is the main occupational toxic lesion in China. In particular, axonal and myelin lesions in the distal thick fibers of the peripheral nervous system may be caused by 2, 5-hexanedione (2, 5-HD), an intermediate metabolite of n-hexane in humans. Hexane has toxic effects not only on the nervous system but also on the liver, kidneys, and reproductive organs. In this paper, we review the progress of research on the mechanism of n-hexane toxic neuropathy.

Abstract
Background Spontaneous hemorrhage of gastro-omental hemangioma is a rare disease. The treatment strategy for this disease changes as it develops. In the acute stage, surgery is the first priority, among which laparoscopic treatment should be the most frequently considered option in large general hospitals. Due to the rarity of this disease, such cases have rarely been reported. Case description We present the first report of two eldely cases with gastro-omental hemangioma with hemorrhage by laparoscopic treatment. Both cases were initially admitted with upper abdominal pain, and abdominal computed tomography (CT) scan revealed masses alongside the greater curvature of the stomach. Laparoscopic surgery was conducted immediately in both patients. The two cases recovered well after surgery, and no obvious abnormalities were observed in the follow-up period. Conclusion Gastro-omental hemangioma rupture remains an uncommon cause of intraperitoneal hemorrhage. Timely diagnosis and surgery are paramount for treatment. Medical institutions with the correct technology and equipment should perform laparoscopic treatment to minimize surgical trauma and promote rapid recovery of patients with abdominal apoplexy.

Abstract
Objective: To analyze the residents' sense of acquisition (recognition, perceptibility and satisfaction) and influencing factors in China's Sanitary City Initiative. Methods: A cross-sectional survey was conducted from December 2020 to February 2021. The data about the residents' sense of acquisition were collected by using questionnaire from 2 465 residents who were aged ≥18 years and had lived in local communities for at least one year in 31, 14 and 16 cities with national sanitary city title in eastern, central and western China the influencing factors of residents' sense of acquisition in China's Sanitary City Initiative were analyzed by using multivariate multilevel model. Results: The total score of residents' sense of acquisition in China's Sanitary City Initiative was 231.15±32.45. After converting the scores according to the 100-score standardized method, the results showed that the recognition score, perception score and the satisfaction score were 85.02, 59.08 and 61.42, respectively. The results of influencing factors analysis showed that education level, gender, marital status, age, prevalence of physical exercise and self-assessment of health status were correlated with the scores of residents' recognition (β:1.24-2.54,all P<0.05); the concentration of inhalable fine particles , the green coverage of built-up area, the level of GDP per capita and the type of residential community, prevalence of physical exercise and self-assessment of health status were correlated with the score of residents' perception (β:1.76-8.86,all P<0.05); the concentration of inhalable fine particles , the green coverage of built-up area, the level of GDP per capita and the type of residential community, education level, prevalence of physical exercise and self-assessment of health status were correlated with the score of residents' satisfaction (β:1.34-6.26,all P<0.05). Conclusions: The total score of residents' sense of acquisition in China's Sanitary City Initiative was relatively high, indicating that the policy has been widely recognized. The detailed management of policy implementation should be strengthened in the future, and more attention needs to be paid to actual needs of the residents to further improve the residents' sense of acquisition in China's Sanitary City Initiative.

Abstract
OBJECTIVE The purpose of this study was to explore the effect of night-shift work on the risk of hypertension for improving workers' health. METHODS A total of 10,038 Chinese participants were constituted in the cross-sectional study. Logistic regression and restricted cubic spline were used to estimate the effect of night shift on hypertension. RESULTS There were higher odds of having hypertension in any night-shift workers (odds ratio [OR], 1.16 [95% confidence interval, 1.03-1.30]) when compared with day workers. Having 5 to 10 night shifts per month were significantly more likely to be hypertensive (OR, 1.19 [95% confidence interval, 1.03-1.38]). The OR for hypertension increased as the number of night shifts increased as the result of the restricted cubic spline. CONCLUSIONS Our results support the hypothesis that night shift is associated with an elevated risk of hypertension.

Abstract
OBJECTIVE Leucine-rich α-2 glycoprotein 1 (LRG1) was recently identified as an amplifier of transforming growth factor-β (TGF-β)-induced kidney fibrosis in animal models. We aimed to study whether urine LRG1 is associated with risk of progression to end-stage kidney disease (ESKD) in individuals with type 2 diabetes. RESEARCH DESIGN AND METHODS A total of 1,837 participants with type 2 diabetes and estimated glomerular filtration rate (eGFR) >30 mL/min/1.73 m2 were recruited from a regional hospital and a primary care facility. Association of urine LRG1 with risk of ESKD (progression to sustained eGFR <15 mL/min/1.73 m2, dialysis, or death resulting from renal causes) was assessed by survival analyses. RESULTS During a median follow-up of 8.6 (interquartile range 5.8-9.6) years, 134 incident ESKD events were identified. Compared with those in the lowest tertile, participants with baseline urine LRG1 in the highest tertile had a 1.91-fold (95% CI 1.04-3.50) increased risk of progression to ESKD, after adjustment for cardiorenal risk factors, including eGFR and albuminuria. As a continuous variable, 1 SD increment in urine LRG1 was associated with a 1.53-fold (95% CI 1.19-1.98) adjusted risk of ESKD. Of note, the association of urine LRG1 with ESKD was independent of plasma LRG1. Moreover, urine LRG1 was associated with rapid kidney function decline and progression to macroalbuminuria, two common pathways leading to ESKD. CONCLUSIONS Urine LRG1, a TGF-β signaling modulator, predicts risk of progression to ESKD independently of clinical risk factors in patients with type 2 diabetes, suggesting that it may be a novel factor involved in the pathophysiological pathway leading to kidney disease progression.

Background
Heart failure (HF) is a common but often unrecognized complication of type 2 diabetes (T2D). Both low eGFR and high albuminuria are strong risk factors for development of HF in diabetic population. However, data on the role of HF in long-term kidney disease outcome are sparse.
Aim
We sought to study the risk for progression to end stage kidney disease (ESKD) after incident HF in multi-ethnic South East Asian people with type 2 diabetes.
Participants and Methods
A total of 1,756 individuals with type 2 diabetes recruited from a regional hospital were followed for a median of 7.3 (interquartile range 6.8-7.8) years. Incident HF was identified according to European Society of Cardiology 2016 criteria. HF was subtyped into preserved ejection fraction (HFpEF) and reduced ejection fraction (HFrEF) with ventricular ejection fraction (LVEF) cut-off at ≥50% and <50% respectively. Progression to ESKD was defined as patients with sustained eGFR <15ml/min per 1.73m2 with confirmation measurement 3 months apart, or on sustained dialysis for at least 3 months or death attributable to renal cause, whichever occurred first. The risk of progression to ESKD after HF was assessed using Cox proportional hazard models.
Results
Average age of participants was 57±11 years with diabetes duration of 11 (IQR 4-15) years. There were 52% Chinese, 22% Malay and 26% Asian Indian in the study participants. We identified 113 incident HF events (65 HFpEF and 48 HFrEF) during 11,869 patient-years (crude incidence rate 9.5 per 1000 patient-years). Individuals with HF occurrence were older, had a longer diabetes duration, higher body mass index, HbA1c and systolic blood pressure, and prevalent diabetic kidney disease (DKD). We identified 75 ESKD events in the follow-up (incidence rate 6.0 per 1000 patient-years) and 22 occurred after incident HF.
Cox regression model showed that incident HF was associated with 7.4-fold (95% CI 4.5-12.2) unadjusted risk for progression to ESKD. The association of HF with subsequent risk for ESKD remained statistically significant (adjusted hazard ratio, HR 2.3, 95% CI 1.3-4.2) after adjustment for multiple clinical risk factors including baseline eGFR and albuminuria. Similar outcome was obtained when death attributable to non-renal cause was taken as a competing risk for ESKD. In a fully adjusted model, both HFpEF and HFrEF patients had a higher risk for progression to ESKD (adjusted HR 2.8, 95%CI 1.4-5.9, and 2.2, 95%CI 1.0-4.7, respectively), as compared to those with no HF events. The incidence rate of ESKD in patients with incident HF was 5.6 per 100 patient-years whilst in propensity score-matched patients without HF event, the rate was 2.1 per 100 patient-years.
Conclusion
Incident HF is a strong independent risk factor for progression to ESKD in individuals with T2D. Our data highlight the importance for prevention, early diagnosis and treatment of HF to improve the renal outcomes in individuals with type 2 diabetes.

Background
Although a low insulin sensitivity (insulin resistance) has been considered as one of the drivers for heart failure, data on the role of insulin resistance in incident HF in diabetic population are still scarce. Estimated glucose disposal rate (eGDR), a novel biomarker for insulin sensitivity derived from three clinically available variables, was developed in type 1 diabetes and recently validated in type 2 diabetes by the gold standard euglycaemic hyperinsulinaemic clamp. We hypothesize that a high level of eGDR is associated with a low risk for incident HF in patients with type 2 diabetes.
Objective
In this prospective cohort study, we aim to examine whether eGDR, the novel biomarker for insulin sensitivity in diabetic population, predicts risk for incident HF in individuals with type 2 diabetes.
Methods
1685 outpatients with type 2 diabetes were recruited from a regional hospital and a primary care centre from January 2011 to March 2014. Incident HF was defined by European Society of Cardiology 2016 criteria (NT-proBNP > 125 pg/ml with echocardiographic evidence). eGDR (mg/kg/min) was calculated as: 21.158 - (0.09 × waist circumference in cm)- (3.407 × hypertension, 1=yes 0=no) - (0.551 × HbA1c%). A higher eGDR indicates a high insulin sensitivity. The association of baseline eGDR with risk for incident HF was examined by survival analysis.
Results
The average age of participants was 57 (SD 11) years old, diabetes duration 11 (SD 9) years, Chinese 52.4%, Malay 21.2% and Asian Indian 26.4. During 6.6 (SD 1.5) years follow-up (11092 patient-years), 155 incident HF events (88 HFpEF with LVEF > 50%, 67 HFrEF with LVEF <= 50%) were identified (crude incident rate 1.4, 95% CI 1.2-1.6, per 100 patient-years). Cox regression model suggested that, as compared to the lowest tertile, participants with eGDR in the highest tertile had 88% lower risk (unadjusted HR 0.12, 95% CI 0.06-0.22) for development of incident HF. The association was only moderately attenuated (adjusted HR 0.32, 95% CI 0.16-0.63) after adjustment for demographic (age, sex, ethnicity) and cardio-renal variables (smoking, body mass index, diabetes duration, resting heart rate, lipid profile, kidney filtration function and albuminuria). As a continuous variable, one SD increment in eGDR was associated with 57% lower risk for HF after adjustment for multiple clinical risk factors (adjusted HR 0.43, 95% CI 0.31-0.59). In the fully adjusted model, a higher level of eGDR was significantly associated with a lower risk for both HFrEF and HFpEF (adjusted HR 0.40, 95% CI 0.23-0.67, and 0.40, 95% CI 0.26-0.63, respectively).
Conclusion
A higher level of eGDR is strongly associated with a lower risk for incident HF in patients with type 2 diabetes, suggesting that insulin resistance may play an important role in pathogenesis of HF. This simple novel biomarker may be explored to stratify risk for incident HF in individuals with type 2 diabetes.

Abstract
Novel monometallic (μ-LL')Ru, Ru(μ-LL'), homobimetallic Ru(μ-LL')Ru, and heterodimetallic Ru(μ-LL')Os and Os(μ-LL')Ru complexes based on two asymmetrical ligands LL' (where LL' = L1L1', L2L2') have been synthesized and characterized. Spectroscopic analysis indicates that all complexes exhibit intense spin-allowed ligand-centered (LC) transitions at 288 nm and Ru-based moderate spin-allowed MLCT absorption between 440-450 nm. The Ru(μ-LL')Os and Os(μ-LL')Ru dinuclear complexes show Os-based unit absorption in the range of 565-583 nm. The Ru-based units of the complexes present different emission intensities due to differing steric hindrance at the coordination sites of the two bridging ligands. The Os(μ-LL')Ru dinuclear complexes present weaker emission intensity than their parent monometallic complexes (μ-LL')Ru. These results indicate that the emission of Os(μ-LL')Ru dinuclear complexes is quenched by the Os(II)-based units.

Abstract
Active and passive exposure to tobacco smoke may increase risk of cognitive decline. However, effects of enhanced the aging process on the association of urinary nicotine metabolites with cognitive impairment remain unclear. In this study, 6657 Chinese older adults completed the physical examinations and cognitive tests. We measured urinary nicotine metabolite levels, mitochondrial DNA copy number (mtDNA-CN), and relative telomere length (RTL) and analyzed effects of urinary nicotine metabolites and their interaction with mtDNA-CN or RTL on cognitive impairment by generalized linear models and qg-computation, respectively. Each 1-unit increase in urinary 3-OHCot, 3-OHCotGluc, CotGluc, or NicGluc levels corresponded to a 1.05-, 1.09-, 1.04-, and 0.90-fold increased risk of cognitive impairment. Each 1-quantile increment in the mixture level of 8 nicotine metabolites corresponded to an increment of 1.40- and 1.34-fold risk of cognitive impairment in individuals with longer RTL or low mtDNA-CN. Urinary 3-OHCotGluc and RTL or mtDNA-CN exhibited an additive effect on cognitive impairment in addition to the mixture of 8 nicotine metabolites and mtDNA-CN. The findings suggested that aging process may increase the risk of tobacco-related cognitive impairment.

Abstract
Objective: Total mesorectal resection (TME) is difficult to perform for rectal cancer patients with anatomical confines of the pelvis or thick mesorectal fat. This study aimed to evaluate the ability of pelvic dimensions to predict the difficulty of TME, and establish a nomogram for predicting its difficulty. Methods: The inclusion criteria for this retrospective study were as follows: (1) tumor within 15 cm of the anal verge; (2) rectal cancer confirmed by preoperative pathological examination; (3) adequate preoperative MRI data; (4) depth of tumor invasion T1-4a; and (5) grade of surgical difficulty available. Patients who had undergone non-TME surgery were excluded. A total of 88 patients with rectal cancer who underwent TME between March 2019 and November 2021 were eligible for this study. The system for scaling difficulty was as follows: Grade I, easy procedure, no difficulties; Grade II, difficult procedure, but no impact on specimen quality (complete TME); Grade III, difficult procedure, with a slight impact on specimen quality (near-complete TME); Grade IV: very difficult procedure, with remarkable impact on specimen quality (incomplete TME). We classified Grades I-II as no surgical difficulty and grades III-IV as surgical difficulty. Pelvic parameters included pelvic inlet length, anteroposterior length of the mid-pelvis, pelvic outlet length, pubic tubercle height, sacral length, sacral depth, distance from the pubis to the pelvic floor, anterior pelvic depth, interspinous distance, and inter-tuberosity distance. Univariate and multivariate logistic regression analyses were performed to identify the factors associated with the difficulty of TME, and a nomogram predicting the difficulty of the procedure was established. Results: The study cohort comprised 88 patients, 30 (34.1%) of whom were classified as having undergone difficult procedures and 58 (65.9%) non-difficult procedures. The median age was 64 years (56-70), 51 patients were male and 64 received neoadjuvant therapy. The median pelvic inlet length, anteroposterior length of the mid-pelvis, pelvic outlet length, pubic tubercle height, sacral length, sacral depth, distance from the pubis to the pelvic floor, anterior pelvic depth, interspinous distance, and inter-tuberosity distance were 12.0 cm, 11.0 cm, 8.6 cm, 4.9 cm, 12.6 cm, 3.7 cm, 3.0 cm, 13.3 cm, 10.2 cm, and 12.2 cm, respectively. Multivariable analyses showed that preoperative chemoradiotherapy (OR=4.97,95% CI: 1.25-19.71, P=0.023), distance between the tumor and the anal verge (OR=1.31, 95% CI: 1.02-1.67, P=0.035) and pubic tubercle height (OR=3.36, 95% CI: 1.56-7.25, P=0.002) were associated with surgical difficulty. We then built and validated a predictive nomogram based on the above three variables (AUC = 0.795, 95%CI: 0.696-0.895). Conclusion: Our research demonstrated that our system for scaling surgical difficulty of TME is useful and practical. Preoperative chemoradiotherapy, distance between tumor and anal verge, and pubic tubercle height are risk factors for surgical difficulty. These data may aid surgeons in planning appropriate surgical procedures.

Abstract
Objective: To explore the relationship between left ventricular artery coupling and left ventricular work in patients with septic shock, and further clarified their predictive value for the prognosis of septic shock. Methods: In total, 56 patients with septic shock admitted in the Department of Critical Care Medicine of Peking Union Medical College Hospital were retrospectively enrolled between January 2016 and July 2021. The hemodynamic indexes and clinical data monitored by pulse indicator continuous cardiac output (PICCO) at different time points were collected. To reveal alterations of arterial elastance index (EaI), end-systolic elastance index (EesI), EaI/EesI, stroke work (SW), total cardiac function (PVA), and left ventricular ejection efficiency (LVEf) in patients with septic shock at different time points. The patients were divided into the death group (n=20) and survival group (n=36) according to the outcome of the ICU. The relationship between left ventricular work and left ventricular arterial coupling and its prognostic value were statistically analyzed. Results: A total of 56 patients were enrolled, 32 males and 24 females, aged (61±15) years. There was a significantly difference in EaI/EesI and LVEf between survivors and non-survivors with septic shock at 6 h (P<0.05). Further analysis showed that the correlation between EaI/EesI and LVEf was most evident at 6 h after intervention. EaI/EesI was negatively correlated with SW (rs=-0.500, P<0.001), and highly negative with LVEf (rs=-0.959, P<0.001). Both univariate logistic regression and multivariate regression analysis showed that EaI/EesI (adjusted OR=42.783, 95%CI: 2.725-671.819, P=0.008) and LVEf (adjusted OR=2.293, 95%CI:1.222-4.301, P=0.010) were risk factors for ICU prognosis of patients with septic shock. The receiver operating characteristic (ROC) curve analysis showed that EaI/EesI [area under the curve (AUC)=0.742±0.083, P=0.004; cut-off value 6.10, sensitivity 88.9%, specificity 65.0%] and LVEf (AUC=0.733±0.084, P=0.006; cut-off value 0.24, sensitivity 88.8%, specificity 60.0%) were both effective indicators for predicting the prognosis of patients with septic shock in the ICU. Moreover, EaI/EesI had a better prognosis value than LVEf (ΔAUC=0.120, Z=6.528, P=0.036). Conclusion: It's indicated that EaI/EesI was significantly correlated with SW and LVEf after 6 h of septic shock intervention; EaI/EesI and LVEf are risk factors and effective predictors of ICU prognosis in patients with septic shock. The predictive efficacy of EaI/EesI is greater than LVEF.

Abstract
β decay of proton-rich nuclei plays an important role in exploring isospin mixing. The β decay of ^{26}P at the proton drip line is studied using double-sided silicon strip detectors operating in conjunction with high-purity germanium detectors. The T=2 isobaric analog state (IAS) at 13 055 keV and two new high-lying states at 13 380 and 11 912 keV in ^{26}Si are unambiguously identified through β-delayed two-proton emission (β2p). Angular correlations of two protons emitted from ^{26}Si excited states populated by ^{26}P β decay are measured, which suggests that the two protons are emitted mainly sequentially. We report the first observation of a strongly isospin-mixed doublet that deexcites mainly via two-proton decay. The isospin mixing matrix element between the ^{26}Si IAS and the nearby 13 380-keV state is determined to be 130(21) keV, and this result represents the strongest mixing, highest excitation energy, and largest level spacing of a doublet ever observed in β-decay experiments.

Abstract
AIMS/HYPOTHESIS We sought to subtype South East Asian patients with type 2 diabetes by de novo cluster analysis on clinical variables, and to determine whether the novel subgroups carry distinct genetic and lipidomic features as well as differential cardio-renal risks. METHODS Analysis by k-means algorithm was performed in 687 participants with recent-onset diabetes in Singapore. Genetic risk for beta cell dysfunction was assessed by polygenic risk score. We used a discovery-validation approach for the lipidomics study. Risks for cardio-renal complications were studied by survival analysis. RESULTS Cluster analysis identified three novel diabetic subgroups, i.e. mild obesity-related diabetes (MOD, 45%), mild age-related diabetes with insulin insufficiency (MARD-II, 36%) and severe insulin-resistant diabetes with relative insulin insufficiency (SIRD-RII, 19%). Compared with the MOD subgroup, MARD-II had a higher polygenic risk score for beta cell dysfunction. The SIRD-RII subgroup had higher levels of sphingolipids (ceramides and sphingomyelins) and glycerophospholipids (phosphatidylethanolamine and phosphatidylcholine), whereas the MARD-II subgroup had lower levels of sphingolipids and glycerophospholipids but higher levels of lysophosphatidylcholines. Over a median of 7.3 years follow-up, the SIRD-RII subgroup had the highest risks for incident heart failure and progressive kidney disease, while the MARD-II subgroup had moderately elevated risk for kidney disease progression. CONCLUSIONS/INTERPRETATION Cluster analysis on clinical variables identified novel subgroups with distinct genetic, lipidomic signatures and varying cardio-renal risks in South East Asian participants with type 2 diabetes. Our study suggests that this easily actionable approach may be adapted in other ethnic populations to stratify the heterogeneous type 2 diabetes population for precision medicine.

Abstract
BACKGROUND Observational studies have shown promising therapeutic effects of long-pulsed neodymium-doped yttrium-aluminum-garnet (LP-Nd:YAG) laser on warts. OBJECTIVE To evaluate whether LP-Nd:YAG laser was superior to cryotherapy for cutaneous warts. METHODS In this study, 150 adult patients with warts were randomized equally to receive laser or cryotherapy every 3 to 4 weeks, for a maximum of 4 sessions. The primary outcomes were the cure rates at 16 weeks and 6 months; secondary outcomes included time to clearance of warts and treatment-related adverse effects. RESULTS There was no difference in the cure rate for laser versus cryotherapy at 16 weeks (54.1% vs 46.7%, respectively) and 6 months (59.5% vs 57.3%, respectively). However, time to clearance of warts, up to 16 weeks and 6 months, tended to be shorter for laser versus cryotherapy (P = .04 and .08, respectively). Post hoc analyses showed a significantly higher cure rate for laser versus cryotherapy in 3 subgroups of human papillomavirus 2/27/57-induced recalcitrant warts but not in their counterpart subgroups. Laser had more mild adverse effects. LIMITATIONS Single center. CONCLUSIONS The overall therapeutic effects of LP-Nd:YAG laser were similar to cryotherapy, but laser may be more effective to relatively recalcitrant warts and may be associated with shorter time to clearance of warts.

Abstract
Inorganic-organic donor-acceptor hybrid compounds are an emerging class of multifunctional crystalline materials with well-defined structures built from semiconductive inorganic and organic components. Perylenediimides (PDIs) are a prominent class of electron-deficient organic dyes, which can undergo consecutive photoinduced electron transfers to generate doublet excited-state radical anions for photoredox-inert chemical bonds. Thus, this is an excellent organic component for building hybrid materials to study the structure-property relationships in organic synthesis. In this context, three molecular structure modified PDI-based hybrid materials, (Me4-PDI)2·SiW12O40 (1), (Me4-Cl4-PDI)2·SiW12O40 (2), and (Me4-Br2-PDI)1.5·HSiW12O40 (3), were studied. By the introduction of different substituent groups at the bay positions, these three hybrid materials were successfully fabricated to investigate the impact of substituent groups on the photocatalytic activity. As expected, all PDI-based hybrid materials easily underwent consecutive photoexcitation to obtain their excited-state radical anions. However, experimental and theoretical analyses showed that these obtained excited-state radical anions displayed unusual bay-substituent-group-dependent photocatalytic conversion activities for the iodoperfluoroalkylation of alkenes and oxidative coupling of amines. Higher conversion yields were obtained for complexes 1 and 3 (bay-unsubstituted and Br-substituted PDI hybrid materials, respectively), and lower conversion was observed for complex 2 (Cl-substituted PDI hybrid material), which is attributed to the excited-state SOMO-1 energies of the PDI radical anions. The structure-property relationship established in this work provides insights for the further exploration of bay-substituted PDI hybrid materials in other small-molecule photocatalytic transformations.

Abstract
BackgroundHeavy metal(loid)s are frequently detected in vegetables posing potential human health risks, especially for those grown around mining areas. However, the oral bioaccessibility and gingival cytotoxicity of heavy metals in wild vegetables remain unclear.MethodsIn this study, we assessed the total and bioaccessible Cr, As, Cd, Pb, and Ni in four wild vegetables from mining areas in Southwest China. In addition, the cytotoxicity and underlying mechanisms of vegetable saliva extracts on human gingival epithelial cells (HGEC) were studied.ResultsThe Plantago asiatica L. (PAL) showed the highest bioaccessible Cr, As, Cd, and Pb, while the greatest bioaccessible Ni was in Taraxacum mongolicum (TMM). The Pteridium aquilinum (PAM), Chenopodium album L. (CAL), and TMM extracts decreased cell viability, induced apoptosis, caused DNA damage, and disrupted associated gene expressions. However, PAL extracts which have the highest bioaccessible heavy metals did not present adverse effects on HGEC, which may be due to its inhibition of apoptosis by upregulating p53 and Bcl-2.ConclusionOur results indicated that polluted vegetable intake caused toxic effects on human gingiva. The heavy metals in vegetables were not positively related to human health risks. Collectively, both bioaccessibility and toxic data should be considered for accurate risk assessment.

Despite continuous artificial tears and bandage mirror treatment, the corneal ulcer perforation in both eyes still occurred successively. After several penetrating keratografts and drug therapy, the ulcer and dissolution could not be prevented. He was admitted to our hospital due to corneal perforation in both eyes.Ophthalmic examination: visual acuity manual/15 cm in the right eye, intraocular pressure T-2, conjunctival sac stenosis, extensive corneal opacity and edema, ulcer about 8 mm, corneal perforation near the corneal limbus about 2 mm×5 mm below.The left eye had no light perception, a central corneal ulcer of about 8 mm, bulge of the posterior elastic layer, no anterior chamber, and atrophy of the eyeball.B-ultrasound showed choroidal detachment of the right eye.On the second day, the patient received right eye intraocular exploration, vitrectomy, ecotopic keratoscleral carrier Boston Ⅱ artificial keratoplasty, glaucoma valve implantation, autogenous ear cartilage implantation, conjunctival occlusion, and left eye lamellar keratoplasty, conjunctival occlusion.Postoperative visual acuity of right eye was -6.50 DS=0.12, intraocular pressure TN, ocular surface was stable.The left eye has no light perception and the ocular surface is stable.
