BACKGROUND: Chronic kidney disease (CKD) poses a major global health challenge, often foreshadowing poor patient outcomes. The C-reactive protein to albumin ratio (CAR) serves as a pivotal biomarker, demonstrating a strong correlation with adverse outcomes in cardiovascular disease (CVD). This study sought to examine the correlation between CAR and the risk of all-cause and cardiovascular mortality in patients with CKD stages 3-5. METHODS: This study utilized data of CKD patients from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2010, with follow-up to December 31, 2019. The optimal CAR cutoff value was identified utilizing the method of maximally selected rank statistics. Multivariable Cox proportional hazards regression model, restricted cubic splines (RCS) model, and subgroup analysis were employed to assess the association between CAR and mortality among CKD patients. RESULTS: During a median (with interquartile range) follow-up period of 115 (112,117) months among 2,841 CKD individuals, 1,893 deaths were observed, including 692 deaths due to CVD events. Based on the RCS analysis, a non-linear correlation was observed between CAR and mortality. Using 0.3 as the optimal CAR cutoff value, the cohort was divided into high and low groups. In the fully adjusted model, CKD patients with high CAR values exhibited an elevated risk of all-cause mortality (hazard ratio [HR] 1.53, 95% confidence interval [CI] 1.28-1.83, P < 0.001) and cardiovascular mortality (HR 1.48, 95% CI 1.08-2.02, P = 0.014). Compared to the population aged >65 years (HR 1.32, 95% CI 0.99-1.76, P = 0.064), the risk of cardiovascular mortality was significantly higher in those aged ≤65 years (HR 2.19, 95% CI 1.18-4.09, P = 0.014) with elevated CAR levels. CONCLUSIONS A notable correlation exists between the elevation of CAR and increased all-cause and cardiovascular mortality, suggesting its potential as an independent indicator for evaluating the prognosis of patients with CKD stages 3-5.

Objective To investigate the effects of lncRNA SBF2-AS1 on the proliferation and invasion of hepatoma cells by regulating the miR-372-3p/CDK6 pathway. Methods Bel7402 and SK-hep1 cells were selected as research objects. The expression levels of SBF2-AS1, miR-372-3p, and CDK6 were up- or down-regulated according to different experimental stages, while the expression levels of miR-372-3p and CDK6 in cells were detected by real-time fluorescence quantitative PCR and Western blot. Dual luciferase reporter assay verified the targeting relationships between SBF2-AS1 and miR-372-3p as well as miR-372-3p and CDK6, respectively. CCK-8, colony formation assay, Transwell, cell cycle assay, and flow cytometry were used to analyze cell proliferation, colony formation, migration/invasion ability, cell cycle activity, and apoptosis. Results SBF2-AS1 was highly expressed in hepatocellular carcinoma cells (P<0.05). SBF2-AS1 knockdown resulted in decreased proliferation and invasion of Bel7402 and SK-hep1 cells (P<0.05). After miR-372-3p knockdown, the proliferation capacity and invasion number of Bel7402 cells were significantly increased. However, the above results were reversed after SBF2-AS1 knockdown (P<0.05). In addition, miR-372-3p targeted CDK6 and inhibited its expression, although over-expressing SFB2-AS1 could reverse the above results (P<0.05). Over-expressing CDK6 could reverse the inhibition of over-expressing miR-372-3p on the proliferation and invasion of Bel7402 cells. Conclusion LncRNA SBF2-AS1 can positively regulate the expression of CDK6 through miR-372-3p. It can also influence the distribution of cell cycle and affect the proliferation and invasion abilities of hepatocellular carcinoma cells.

Acute kidney injury(AKI),a clinical syndrome caused by various factors,is characterized by a rapid decline in kidney function in a short period of time.AKI affects the short-term prognosis of patients and may also induce chronic kidney disease(CKD).However,the current treatment options for AKI mainly focus on symptom management.Specific therapeutic measures available for the prevention of transition from AKI to CKD are very limited in number.Histones are basic proteins that intricately bind the DNA in chromosomes.After translation,histones undergo various modifications on their amino-terminal tails,such as methylation,acetylation,phosphorylation,ubiquitination,and lactylation,collectively forming the"histone code",which affects the expression of genes mainly by regulating the elastic structure of chromatin or recruiting specific proteins.Extensive research conducted in recent years on histone post-translational modifications(PTMs)has also sparked continuous interest in their association with the AKI-to-CKD transition.Therefore,this paper highlights the significant role of PTMs in the process of AKI developing and progressing to CKD,with a view to finding new approaches to preventing the progression of AKI to CKD.

Objective To investigate the effect of uric acid on the clinicopathological characteristics and prognosis of immunoglobulin A nephropathy(IgAN)in patients with stage 3-4 chronic kidney disease(CKD).Methods The clinical and pathological data of 263 IgAN patients who had stage 3-4 CKD and who had confrimed diagosis through renal biopsy at the First Affiliated Hospital of Air Force Medical University between December 2008 and January 2020 were retrospectively collected.According to the levels of uric acid,the patients were divided into a hyperuricemia group(n=102)and a normal uric acid group(n=161),and the clinicopathological characteristics of the two groups were compared accordingly.With progression to end-stage renal disease or death as the endpoint event,the renal survival rate of the two groups was compared by the Kaplan-Meier method and the relationship between uric acid and the prognosis was analyzed by Cox regression and LASSO regression.Results Compared with the normal uric acid group,the hyperuricemia group had a significantly higher proportion of male patients and patients with a history of hypertension,a significantly higher level of blood urea nitrogen,and lower levels of estimated glomerular filtration rate and high-density lipoprotein.In terms of pathology,patients in the hyperuricemia group had significantly higher proportion of glomerulosclerosis,higher mesangial hypercellularity,and higher tubular atrophy/interstitial fibrosis(P＜0.05).Kaplan-Meier curve showed that there was a significant difference in renal survival rate between the two groups(P＜0.000 1).LASSO regression showed that high uric acid was a risk factor for the prognosis of IgAN patients with stage 3-4 CKD.Further multivariate Cox analysis showed that,compared with the normal uric acid group,the hyperuricemia group had a higher risk of incurring composite outcomes(hazard ratio[HR]=1.61,95％confidence interval[CI]:1.10-2.34).When uric acid was used as a continuous variable,the increase of 1 mg/dL in uric acid concentration was associated with an increased HR of 1.18(95％CI:1.08-1.29)for the composite outcome.Conclusion High uric acid is a risk factor for poor renal prognosis in IgAN patients with stage 3-4 CKD and reducing uric acid levels may effectively improve the prognosis of high-risk IgAN patients.

Objective:To investigate the association between hepatic echinococcus granulosus infection and necrosis with gene polymorphism of interleukin-10 (IL-10) and tumor necrosis factor-α (TNF-α), and to identify the related factors at the gene level.Methods:A total of 106 patients with hepatic echinococcosis who underwent surgical treatment in the department of hepatobiliary surgery, People′s Hospital of Xinjiang Uygur Autonomous Region from January 2018 to December 2020 were selected. Patients with necrosis caused by hepatic echinococcus granulosus infection were selected as the observation group, and patients without necrosis caused by hepatic echinococcus granulosus infection were selected as the control group, with 53 cases in each group. The serum levels of IL-10 and TNF-α were detected by enzyme-linked immunosorbent assay (ELISA). The polymorphisms of IL-10 (-592, -1082) and TNF-α (rsl800630) were detected by polymerase chain reaction (PCR). The levels of IL-10 and TNF-α and their gene polymorphisms were analyzed.Results:The levels of serum IL-10 and TNF-α in the observation group were significantly higher than those in the control group (all P<0.05); There was significant difference in genotype and allele frequency of IL-10 (-592, -1082) and TNF-α (rsl800630) (all P<0.05). The serum IL-10 level of CC genotype patients with IL-10 gene -592C/A locus in the observation group was higher than that of CA+ AA genotype patients, with statistically significant difference ( P<0.05). The serum IL-10 level in patients with TT genotype at -1082T>A of IL-10 gene in the observation group was higher than that in patients with TA+ AA genotype, with statistically significant difference ( P<0.05). The serum TNF-α level in patients with CC genotype at rsl800630C/A locus of TNF-α gene in the observation group was higher than that in patients with CA+ AA genotype, with statistically significant difference ( P<0.05). Conclusions:The changes of IL-10 (-592, -1082) and TNF-α (rsl800630) gene polymorphisms may be associated with hepatic echinococcus granulosus infection and necrosis.

Objective To evaluate the significance of contrast medium (CM) volume and estimated glomerular filtration rate (CM/eGFR) in predicting contrast-induced nephropathy (CIN) after PCI. Methods A total of 307 patients after PCI were enrolled from Nanfang Hospital from May 2014 to October 2015. The patients were divided into the CIN group(n = 29) and the non-CIN group(n = 278) according to whether CIN within 72 hours after PCI. The baseline renal function was assessed by the sCr and CyC, respectively. Results Twenty-nine patients (9.4%, 29/307) developed CIN. There were significant differences in Age, CM、NTpro-BNP、IABP、 Periprocedural Hypotension、Preprocedural sCr/CyC between two groups (P < 0.05, respectively). The result of multivariate logistic regression analysis showed that Age, Cardiac function ≥Ⅲ level, IABP, use CCB, CM/eGFRMDRD, CM/eGFRCyC were independent risk predictors for CIN, respectively. Receiver Operating Characteristic (ROC) curve analysis showed that the area under the curve of CM/eGFRMDRD(AUC = 0.838) was superior to CM/eGFRCyC (AUC = 0.805) without significant difference. The sensitivity and specificity were 79.3%and 76.3%(Cut-off Point = 2.094), respectively. Conclusion Both the CM/eGFRMDRD and CM/eGFRCyC may be good methods to determine maximum CM before PCI and to predict CIN after PCI currently, without significant differences between these two predictors.

OBJECTIVETo evaluate the application of small intestine double stoma and succus entericus reinfusion in the patients with severe intra-abdominal infection.

METHODSTen patients with high intestinal perforation from February 2005 to November 2014 were enrolled in the study. All the cases received emergency operation. Small bowel with intestinal perforation was resected, and double stoma was applied in the proximal and distal small intestine. When abdominal infection under control, total enteral nutrition was successfully administered from nasogastric tube. The succus entericus from the proximal intestine was collected and transfused back to the distal intestine. Stool was collected and fecal nitrogen, fat and carbohydrate contents were determined. Related serum protein levels were measured.

RESULTSAs compared to pre-reinfusion, the absorption rate of carbohydrate [(90.9±7.8)% vs. (82.7±15.2)%], fat [(87.6±6.4)% vs. (59.1±10.8)%], and nitrogen [(82.4±9.8)% vs. (67.2±15.4)%] increased after succus entericus reinfusion (P<0.05). The serum protein levels increased significantly as well[fibronectin: (285.6±3.6) vs. (157.0±22.6) mg/L, P<0.01; transferrin: (4.86±0.21) vs. (3.60±0.25) g/L, P<0.05; pre-albumin: (291.3±112.5) vs. (199.1±53.3) mg/L, P<0.05].

CONCLUSIONSmall intestine double stoma and succus entericus reinfusion are effective in improving the absorption of carbohydrate, fat and nitrogen in the patients with severe intra-abdominal infection.
