Gliomas are the most common central nervous system tumours; they are highly aggressive and have a poor prognosis. RGS16 belongs to the regulator of G-protein signalling (RGS) protein family, which plays an important role in promoting various cancers, such as breast cancer, pancreatic cancer, and colorectal cancer. Moreover, previous studies confirmed that let-7c-5p, a well-known microRNA, can act as a tumour suppressor to regulate the progression of various tumours by inhibiting the expression of its target genes. However, whether RGS16 can promote the progression of glioma and whether it is regulated by miR let-7c-5p are still unknown. Here, we confirmed that RGS16 is upregulated in glioma tissues and that high expression of RGS16 is associated with poor survival. Ectopic deletion of RGS16 significantly suppressed glioma cell proliferation and migration both in vitro and in vivo. Moreover, RGS16 was validated as a direct target gene of miR let-7c-5p. The overexpression of miR let-7c-5p obviously downregulated the expression of RGS16, and knocking down miR let-7c-5p had the opposite effect. Thus, we suggest that the suppression of RGS16 by miR let-7c-5p can promote glioma progression and may serve as a potential prognostic biomarker and therapeutic target in glioma.

Objective To explore the diagnostic value of artificial intelligence (AI) cytology combined with DNA-image cytometry (DNA-ICM) auxiliary diagnostic system for the identification of benign and malignant pleural effusion and ascites. Methods Liquid-based cytology technology (LCT), DNA-ICM, AI, and AI combined with DNA-ICM were used to identify benign and malignant pleural effusion and ascites specimens in 360 cases, and their sensitivity, specificity, accuracy, Kappa value, Youden index and AUC were statistically analyzed. Results The sensitivity, specificity, and accuracy of AI combined with DNA-ICM in detecting benign and malignant pleural effusion and ascites were 95.23%, 94.12%, and 94.44%, respectively, which were higher than those of the three other separate detection methods (all P < 0.05). The kappa values of LCT, DNA-ICM, and AI were 0.646, 0.642, and 0.586; their Youden index values were 0.693, 0.687, and 0.676, and their AUC values were 0.846, 0.843, and 0.838, respectively. The Kappa value of AI combined with DNA-ICM was 0.869, the Youden index was 0.893, and AUC was 0.947, which were all higher than those of the three detection methods alone. Conclusion Among the three separate detection methods, LCT has the highest reliability, authenticity, and diagnostic value, and it can be used as a common method for the clinical identification of benign and malignant pleural effusion and ascites. The diagnostic performance of AI combined with DNA-ICM auxiliary diagnosis system in identifying benign and malignant pleural effusion and ascites is better than those of the three separate detection methods and can be used as a reliable method for the clinical identification of benign and malignant pleural effusion and ascites.

The clinical features, examination findings and genetic testing results of a newborn with neurobehavioral developmental abnormality caused by the PAK3 gene mutation in the Department of Neonatology, Anhui Provincial Children′s Hospital were retrospectively analyzed in November 11, 2021.The male 9-day-old newborn presented with the difficult-to-wean for 9 days after birth.The child had repeated startle reflexes, decreased muscle tension in the extremities, and partial primitive reflexes.Amplitude-integrated electroencephalogram (aEEG) showed the lower and upper boundary voltage of 10 μV and 40 μV, respectively.Obvious mature sleep-wake cycles were not found, and 2 electric seizures were recorded.The aEEG suggested the moderate-to-severe abnormal aEEG.Magnetic resonance imaging showed that the corpus callosum was slightly thinner.The family-centered diagnostic exosome sequencing showed a missense mutation of the PAK3 gene[c.1327 (exon18) G>A, p.G443R], which has not been previously reported at home and abroad.This case enriched the clinical phenotype of the PAK3 gene mutation and suggested the potential value of whole genome sequencing in clinical diagnosis and genetic guidance.

Objective To evaluate the impact of customized rehabilitation exercise plans based on the results of cardiopulmonary exercise test(CPET)on cardiac function and prognosis in patients with chronic heart failure(CHF).Methods A total of 52 CHF patients admitted to Chengde Central Hospital from February 2020 to September 2021 were selected as the study subjects,and the patients were divided into observation group and control group according to the principle of randomized controlled study,with 26 cases in each group.The control group received rehabilitation treatment excluding exercise.The observation group was given routine rehabilitation treatment and high-intensity rehabilitation exercise plans based on CPET guidance.Above anaerobic threshold Δ50%power was exercise intensity,exercise time was 30 minutes/day,4 days/week,and intervention period was 12 weeks.Before and 12 weeks after intervention,CPET functional indicators,serum brain natriuretic peptide(BNP),left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVEDD),and 6-minute walking distance(6MWD)were measured.The Minnesota CHF quality of life questionnaire(LiHFe)was used to evaluate patient's quality of life,readmission rate and cardiogenic mortality within 1 year of follow-up,and univariate and multivariate Logistic regression analysis was used to analyze factors affecting readmission of CHF patients.Results ① Cardiopulmonary function indicators:there was no statistically significant difference in the anaerobic threshold,peak oxygen uptake,and peak oxygen pulse of CPET functional indicators before and after intervention in the control group,after intervention,the CPET functional indicators in the observation group were significantly higher than those before intervention,and the above indexes in the observation group were significantly higher than those of the control group[anaerobic threshold(mL·min-1·kg-1):10.77±1.40 vs.9.59±1.11,anaerobic threshold(%ped):78.95±11.39 vs.70.09±6.48,peak oxygen uptake(mL·min-1·kg-1):15.63±1.36 vs.14.27±1.72,peak oxygen uptake(%ped):72.42±6.91 vs.63.41±7.31,peak oxygen pulse(mL/order):11.38±1.29 vs.9.05±1.64,peak oxygen pulse(%ped):90.23±10.16 vs.80.53±6.73,all P＜0.05].②Serum indicators,cardiac function indicators,exercise ability indicators,and quality of life evaluation:there was no statistically significant difference in serum indicators BNP,cardiac function indicators LVEDD,LVEF,exercise ability indicators 6MWD,and quality of life LiHFe scores between the two groups before intervention.After intervention,BNP and LiHFe scores were significantly reduced compared with before intervention,while LVEF and 6MWD were both increased compared with before intervention,and the changes of the above indexes in the observation group were more significant than those in the control group[BNP(ng/L):313.25±77.91 vs.445.89±110.67,LVEF:0.41±0.08 vs.0.37±0.06,6MWD(m):495.62±91.35 vs.416.04±65.29,LiHFe score:23.27±6.02 vs.29.50±4.61,all P＜0.05].③ Prognostic follow-up:the readmission rate within 1 year in the observation group was significantly lower than that in the control group(23.08%vs.53.85%),and there was no statistically significant difference in the mortality rate of cardiogenic diseases between the two groups.④Logistic univariate analysis showed that hyperlipidemia,New York Heart Association(NYHA)grading,BNP,and rehabilitation exercise were factors that affect the prognosis of CHF patients[odds ratio(OR)and 95%confidence interval(95%CI)were 0.098(0.019-0.494),0.069(0.016-0.294),1.018(1.007-1.029),and 3.889(1.178-12.841),respectively,all P＜0.05].Multivariate analysis showed that after adjusting for other factors,hyperlipidemia,NYHA grading,and BNP were risk factors affecting the prognosis of CHF patients(OR and 95%CI were 0.068(0.007-0.687),0.048(0.005-0.415),1.016(1.002-1.030),respectively,with P＜0.05],the use of rehabilitation exercise therapy was a protective factor affecting the prognosis of CHF patients[OR and 95%CI were 11.179(1.135-10.124),P＜0.05].Receiver operator characteristic curve(ROC curve)analysis showed that hyperlipidemia,NYHA grading,BNP,rehabilitation exercise therapy,and combined testing all had predictive value for the patient's prognosis(all P＜0.05),and the prediction value of joint detection was the highest,with the area under the ROC curve(AUC)=0.984 and P = 0.000.Conclusion Developing a high-intensity individualized cardiac exercise rehabilitation plan under the guidance of CPET can help improve the cardiopulmonary function,cardiac function,and quality of life of CHF patients,which is of great benefit for improving the long-term prognosis of CHF patients and has high safety.

Discipline evaluation is an important measure to promote the virtuous circle of discipline construction, and is an indispensable link in the process of discipline development in public hospitals. After becoming a directly affiliated hospital of a " double first-class" university, in order to improve the comprehensive strength and influence, a hospital built and applied a disciplinary evaluation system in four directions: talent construction, clinical medicine, scientific research ability, and teaching work. According to the evaluation results, the hospital′s disciplines were divided into three categories, namely, advantageous disciplines, cultivating disciplines and potential disciplines, and development strategies were established at different levels, providing policy support and financial support, especially in the field of scientific research and teaching, to accelerate to make up for shortcomings. Through exploration and practice, the talent team, scientific research and teaching level, discipline reputation, and comprehensive strength of the hospital had been significantly improved, providing effective support for the high-quality development of the hospital.

Objective:To explore the effects of Bailing capsules combined with salvianolate on inflammatory cytokines, renal vas-cular endothelia and renal function in diabetic nephropathy inⅣphase. Methods:Totally 60 patients with diabetic nephropathy in IV phase were randomly divided into the control group (30 cases) and the treatment group (30 cases). The control group was given the conventional and salvianolate therapy, and the treatment group was treated with Bailing capsules additionally. The treatment course was 3 months. The changes of serum creatine(SCr), urean itrogen (BUN), creatinine clearance rate (Ccr), ethelin (ET-1), interleukin-6 (IL-6), tumor necrosis factor (TNF-a) and C-reactive protein (CRP) were detected before and after the treatment. Results:After the 3-month treatment, SCr, BUN, IL-6, TNF-a, CRP and ET-1 were significantly decreased in the two groups with statistical signifi-cance, and Ccr was significantly increased in the treatment group (P<0. 05), and the changes in the treatment group were significant-ly better than those in the control group (P<0. 05). After the treatment, the blood glucose, blood lipids, glycosylated hemoglobin and the other indicators had no significant changes in the two groups (P>0. 05). There was no significant difference in the incidence of adverse drug reactions between the two groups (P>0. 05). Conclusion:The combination of Bailing capsules and salvianolate can re-duce the inflammatory reaction and improve renal vascular endothelial function and renal function in the patients with diabetic nephrop-athy in Ⅳ phase with promising safety and few adverse reactions.
