Objective To explore the prognostic value of albumin/globulin(AGR)in patients with stage Ⅲ-Ⅳ non-small cell lung cancer(NSCLC)treated with first-line chemotherapy.Methods From January 2016 to December 2020,288 patients with ad-vanced NSCLC initially diagnosed in the Affiliated Hospital of Xuzhou Medical University were selected.AGR critical value was deter-mined by receiver operating characteristic(ROC)curve,patients were divided into high AGR group(n=104)and low AGR group(n=184).Survival curve was plotted using Kaplan-Meier method,overall survival(OS)and progression-free survival(PFS)were com-pared between the two groups.COX proportional risk regression model was used to analyze the factors affecting prognosis of NSCLC pa-tients.Results The critical value of AGR was 1.5,the area under the curve of AGR was 0.693,the sensitivity was 76.8％,and the specificity was 58.3％.AGR was correlated with age,pathological type and curative effect(P＜0.05).The high AGR group had longer PFS and OS than the low AGR group(9 months vs 5months,25months vs 19months).Multivariate COX regression analysis showed that low level of AGR was an independent risk factor for NSCLC patients(P＜0.05).Conclusion AGR can be used as an effective prognos-tic indicator for patients with stage Ⅲ-Ⅳ NSCLC treated with first-line chemotherapy,and low levels of AGR suggest poor prognosis.

Objective To investigate the impact of matrine(Mat)on renal injury in rats with chronic glomerulonephritis by regulating the monocyte chemotactic protein-1(MCP-1)/chemokine C-C-motif receptor 2(CCR2)signaling pathway.Methods The rat model of chronic glomerulonephritis was established by subcutaneous injection of bovine serum albumin,the rats were randomly grouped into control group,model group,low and high dose matrine groups(Mat-L group,Mat-H group),and matrine+CCR2 group(Mat+CCR2 group),with 10 rats in each group.After continuous gavage for 4 weeks,24-hour urine protein excretion was measured;spleen and thymus were removed and organ index was calculated;The levels of blood urea nitrogen(BUN)and serum creatinine(Scr)in the serum of each group were detected,the pathological changes of renal tissue were observed by HE staining;the levels of tumor necrosis factor α(TNF-α)and interleukin(IL)-6 in renal tissue were detected by ELISA;Flow cytometry was applied to detect the proportion of T lymphocyte subsets in peripheral blood of rats in each group;Western blotting was applied to determine the expression of MCP-1 and CCR2 proteins.Results The spleen index and thymus index of rats in the model group rats were obviously reduced,and there were a large number of inflammatory cell infiltration in the renal tissue,the 24-hour urine protein,BUN,Scr,TNF-α,IL-6,and the expression of MCP-1 and CCR2 obviously increased,the peripheral blood T cell subpopulations CD3+,CD4+,and CD4+/CD8+ratio obviously reduced,the proportion of CD8+obviously increased(P＜0.05);The spleen index and thymus index of rats in the Mat-L and Mat-H groups of rats increased,and the phenomenon of renal tissue inflammation and infiltration improved,the 24-hour urine protein,BUN,Scr,TNF-α,IL-6,and the expression of MCP-1 and CCR2 obviously decreased,the peripheral blood T cell subpopulations CD3+,CD4+,and CD4+/CD8+ratio obviously increased,the proportion of CD8+obviously decreased(P＜0.05);CCR2 attenuated the effect of Mat-H on immune function in rats with chronic glomerulonephritis.Conclusion Matrine can alleviate the inflammatory damage and improve the peripheral immune function of rats with chronic glomerulonephritis,and its mechanism may be related to the inhibition of MCP-1/CCR2 signaling pathway.

Autism spectrum disorder (ASD) is a group of neurodevelopmental behavioral disorders, with the annually increased incidence in recent years.As one of the core symptoms of ASD, sensory abnormality not only affects the skill acquisition of affected children, but also brings great pain to caregivers and families.It is shown that early intervention of sensory abnormality can significantly improve the prognosis of ASD.However, early intervention depends on the early identification and diagnosis of sensory abnormality by clinicians.This study aims to review the clinical features, assessment tools, and intervention methods of sensory abnormalities in ASD children in recent years, thus contribu-ting to the accurate and effective diagnosis, and timely intervention of ASD.

Objective: To compare the application effect of the colonoscopy, fecal immunochemical test (FIT) and novel risk-adapted screening approach in colorectal cancer screening in Xuzhou population. Methods: From May 2018 to April 2019, 4 280 subjects aged 50-74 were recruited from Gulou district, Yunlong district and Quanshan district of Xuzhou. They were randomly assigned to the colonoscopy group (n=863), FIT group (n=1 723) and novel risk-adapted screening approach group (n=1 694) according to the ratio of 1∶2∶2. For the novel risk-adapted screening approach group, after the risk assessment, high-risk subjects were invited to undergo colonoscopy and low-risk subjects were invited to undergo FIT examination. All FIT positive subjects were invited to undergo colonoscopy. Colonoscopy participation rate [(the number of colonoscopies completed/the number of colonoscopies invited to participate)×100%], detection rate of colorectal lesions [(the number of diagnosed patients/the number of colonoscopies completed)×100%], colonoscopy resource load (the number of colonoscopies completed/the number of diagnosed advanced tumors) and FIT resource load in each group were calculated and compared. Results: The age of all subjects was (61±6) years old, including 1 816 males (42.43%). There was no statistically significant difference in the socio-demographic characteristics of the subjects in different screening groups. The colonoscopy participation rate was 22.60% (195/863) in the colonoscopy group, 57.04% (77/135) in the FIT group, and 33.94% (149/439) in the novel risk-adapted screening approach group, respectively. The colonoscopy participation rate was higher in the FIT group than in the colonoscopy group and the novel risk-adapted screening approach group (P<0.001). The colonoscopy participation rate of novel risk-adapted screening group was significantly higher than the colonoscopy group (P<0.001). The detection rates of advanced tumors were 6.67% (13/195), 9.09% (7/77) and 8.72% (13/149), respectively, and the difference was not statistically significant (P>0.05). The colonoscopy resource load (95%CI) was 15 (13-17) in the colonoscopy group, 11 (9-14) in the FIT group and 11 (10-13) in the novel risk-adapted screening approach group, respectively. Among them, the colonoscopy resource load of high-risk individuals in the novel risk-adapted screening approach group was 12 (9-15). FIT resource loads (95%CI) were 207 (196-218) and 88 (83-94) in the FIT group and the novel risk-adapted screening approach group. Conclusion: The combined application of risk-adapted screening approach and FIT may have a good application effect in colorectal cancer screening.
