Objective:To examine the associations of BMI and waist circumference (WC) with the risk of chronic kidney disease (CKD) and its subtypes in adults in China.Methods:The data from the China Kadoorie Biobank were used. After excluding those with cancer, coronary heart disease, stroke, or CKD at baseline survey, 480 430 participants were included in this study. Their body height and weight, and WC were measured at baseline survey. Total CKD was defined as diabetic kidney disease (DKD), hypertensive nephropathy (HTN), glomerulonephritis (GN), chronic tubulointerstitial nephritis (CTIN), obstructive nephropathy (ON), CKD due to other causes, and chronic kidney failure. Cox proportional hazards regression model was used to estimate the associations between exposure factors and risks of outcomes.Results:During a follow-up period of (11.8±2.2) years, 5 486 cases of total CKD were identified, including 1 147 cases of DKD, 340 cases of HTN, 1 458 cases of GN, 460 cases of CTIN, 598 cases of ON, 418 cases of CKD due to other causes, and 1 065 cases of chronic kidney failure. After adjusting for socio-demographic factors, lifestyle factors, baseline prevalence of hypertension and diabetes, and WC and compared to participants with normal BMI (18.5-23.9 kg/m 2), the hazard ratios ( HRs) of total CKD for underweight (<18.5 kg/m 2), overweight (24.0-27.9 kg/m 2), and obese (≥28.0 kg/m 2) were 1.42 (95% CI: 1.23-1.63), 1.00 (95% CI: 0.93-1.08) and 0.98 (95% CI: 0.87-1.10), respectively. Stratification analysis by WC showed that BMI was negatively associated with risk for total CKD in non-central obese participants (WC: <85.0 cm in men and <80.0 cm in women) ( HR=0.97, 95% CI: 0.96-0.99), while the association was positive in central obese participants (≥90.0 cm in men and ≥85.0 cm in women) ( HR=1.03, 95% CI: 1.01-1.05). The association between BMI and GN was similar to that of total CKD. BMI was associated with an increased risk for HTN, with a HR of 1.12 (95% CI: 1.06-1.18) per 1.0 kg/m 2 higher BMI. After adjusting for potential confounders and BMI, compared to participants with non-central obesity, the HRs for pre-central obesity (WC: 85.0-89.9 cm in men and 80.0-84.9 in women) and central obesity were 1.26 (95% CI: 1.16-1.36) and 1.32 (95% CI: 1.20-1.45), respectively. With the exception of HTN and CTIN, WC was positively associated with risks for all CKD subtypes. Conclusions:BMI-defined underweight and central obesity were independent risk factors for total CKD, and BMI and WC had different associations with risks for disease subtypes.

By applying "homeostasis" to the study of the meridian and collateral system， the concept of meridian and collateral homeostasis has been proposed which refers to a balanced and stable state of meridian and collateral system， and plays an important role in maintaining body health and can provide a reference for the diagnosis and treatment of diseases. Phenomics realizes the cross-scale correlation from micro-phenotypic data， such as genome， proteome， and metabolome， to macro-phenotypic data， such as physiological state， behavioral activities， and external manifestations. From the perspective of phenomics， this paper proposes a meridian and collateral homeostasis dynamic mapping model of "macroscopic signs and microscopic expression". This model combines macro signs such as the four examinations of traditional Chinese medicine （TCM）， biophysical indicators of acupoints， and micro expression information such as genes， proteins， and metabolism， and systematically investigates the relationship between meridian and collateral homeostasis and health and disease， thereby providing ideas and references for the identification of pre-disease states as well as precise diagnosis and treatment in TCM.

Objective:To retrieve, summarize, evaluate and integrate the best evidence for the prevention and management of center venous catheter dysfunction in hemodialysis patients.Methods:The relevant literature on prevention of center venous catheter dysfunction in hemodialysis patients was systematically searched in UpToDate, BMJ Best Practice, Cochrane Library, National Guideline Clearinghouse, Guidelines International Network, National Kidney Foundation, PubMed, CNKI and other databases, including guidelines, clinical decision-making, evidence summary, systematic evaluation and expert consensus. The search period was from January 1st, 2013 to March 1st, 2023. Two researchers independently evaluated the quality of the literature, evaluated the quality of the included literature and extracted evidence.Results:A total of 15 articles were included, including three guidelines, three clinical decision-making, five expert consensus, two systematic evaluations, one evidence summary and one government document. Ultimately, seven themes and 32 best evidence were formed, including personnel training and management, evaluation and monitoring, catheter insertion, catheter maintenance, drug prevention, catheter dysfunction management and health education.Conclusions:This study summarizes the best evidence for the prevention and management of center venous catheter dysfunction in hemodialysis patients. Medical staff can choose and apply this evidence-based basis based on clinical situations and patient preferences, thereby reducing the incidence of catheter dysfunction.

Objective:To explore the risk factors for central venous catheter (CVC) dysfunction in hemodialysis patients, construct a risk prediction model, and verify the model's predictive performance.Methods:The retrospective research method was adopted. From January 2021 to August 2023, convenience sampling was used to select 442 patients who underwent hemodialysis by CVC at the First Hospital of Shanxi Medical University, Shanxi Provincial People's Hospital, and Shanxi Bethune Hospital as the study subjects. Patients were divided into a modeling group ( n=309) and a validation group ( n=133) according to the order of time of CVC. The modeling group was divided into groups based on whether patients experienced catheter dysfunction. Multivariate Logistic regression was used to analyze the influencing factors of hemodialysis catheter dysfunction and construct a nomogram model. The model's predictive performance was evaluated using the calibration curve, area under the receiver operating characteristic curve ( AUC), and the Hosmer Lemeshow goodness of fit test. Results:Multivariate Logistic regression analysis showed that history of thrombosis, blood hypercoagulability, catheterization site, catheter-related infection, and catheterization duration were influencing factors for catheter dysfunction in hemodialysis ( OR=5.119, 5.174, 6.362, 2.913, and 5.353; all P<0.05). The above five factors were used as independent variables to construct a nomogram. Internal validation of the model showed that the Hosmer Lemeshow test was χ 2=10.828, P=0.212, and AUC was 0.837 [95% confidence interval (0.781, 0.893) ], and the calibration curve fitted well with the ideal curve. External validation of the model indicated that the Hosmer Lemeshow test was χ 2=1.944, P=0.925, and AUC was 0.825 [95% confidence interval (0.744, 0.906) ], and the calibration curve almost coincided with the ideal curve. Conclusions:The constructed nomogram can predict the risk of catheter dysfunction in hemodialysis patients and provide a reference for nursing staff to develop corresponding interventions.

OBJECTIVE To investigate the effect and mechanism of dihydroartemisinin(DHA)on lipo-polysaccharide(LPS)-induced acute lung injury(ALI)in mice using whole-genome sequencing.METHODS An ALI mouse model was established via intraperitoneal injection of 10 mg·kg-1 lipopolysaccharide.The mice were divided into normal control group(n=10),model group(n=10)and model+DHA group(n=10).The mice in the model+DHA group were injected intraperitoneally with 20 mg·kg-1 DHA,while those in the normal control group and LPS group were injected intraperitoneally with solvent of DHA,saline containing 1%Tween 80 and 10%Macrogol 400.The mice were executed 24 h after drug administration.The wet and dry weight ratio(W/D)of lung tissue was calculated.Hematoxylin-eosin(HE)staining was used to observe histopathological damage in the lung.Classified counts of inflamma-tory cells in alveolar lavage fluid were performed.Enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of interleukin-1β(IL-1β),IL-6,and tumor necrosis factor-α(TNF-α)in alveolar lavage fluid.Real-time quantitative PCR(RT-qPCR)was used to detect mRNA levels of placenta-specific 8(Plac8),Toll-like receptor 7(TLR7),IL-1β,IL-6 and TNF-αin lung tissue.The whole gene transcriptome was sequenced by RNA transcriptome sequencing(RNA-seq)using the Illumina HiSeq high-throughput sequencing platform before the function and signal pathway of differentially expressed gene mRNA between the groups were enriched and analyzed using GO and KEGG enrichment analysis methods.RESULTS Compared with the model group,the lung W/D values of mice,the pathological damage,inflammatory cells in alveolar lavage fluid,expression levels of IL-1β,IL-6 and TNF-α in alveolar lavage fluid(P<0.01,P<0.01,P<0.01),and the mRNA expression levels of IL-1β,IL-6 and TNF-α were significantly reduced in lung tissues in the model+DHA group(P<0.01,P<0.05,P<0.05).Whole gene transcriptome sequencing revealed that immune-related Plac8 and TLR7 genes were significantly upregu-lated(P<0.01)in mouse lung tissue of the model group but significantly downregulated(P<0.05)in mouse lung tissue of the model+DHA group.The results of RT-qPCR of Plac8 and TLR7 verified the results of whole gene transcriptome sequencing.GO and KEGG analysis showed that Plac8 and TLR7 were mainly related to the regulation of cytokine production,T/B cell activation and signal transduction,chemo-kine signal transduction and NF-κB signal transduction.CONCLUSION DHA might reduce LPS-induced lung damage and ameliorate the inflammatory condition in lungs of ALI mice.The mechanism of action may be that DHA negatively regulates the signaling pathways involved in TLR7 and Plac8 by decreasing the expressions of TLR7 and Plac8 mRNA before regulating a series of immune responses such as secretion of inflammation-related cytokines and activation of immune cells,thereby reducing inflam-matory damage in lungs.

Consecutively hospitalized patients with confirmed coronavirus disease 2019 (COVID-19) in Wuhan, China were retrospectively enrolled from January 2020 to March 2020 to investigate the association between the use of renin-angiotensin system inhibitor (RAS-I) and the outcome of this disease. Associations between the use of RAS-I (angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB)), ACEI, and ARB and in-hospital mortality were analyzed using multivariate Cox proportional hazards regression models in overall and subgroup of hypertension status. A total of 2771 patients with COVID-19 were included, with moderate and severe cases accounting for 45.0% and 36.5%, respectively. A total of 195 (7.0%) patients died. RAS-I (hazard ratio (HR)= 0.499, 95% confidence interval (CI) 0.325-0.767) and ARB (HR = 0.410, 95% CI 0.240-0.700) use was associated with a reduced risk of all-cause mortality among patients with COVID-19. For patients with hypertension, RAS-I and ARB applications were also associated with a reduced risk of mortality with HR of 0.352 (95% CI 0.162-0.764) and 0.279 (95% CI 0.115-0.677), respectively. RAS-I exhibited protective effects on the survival outcome of COVID-19. ARB use was associated with a reduced risk of all-cause mortality among patients with COVID-19.
