Background. Persistent inflammation has been recognized as an important comorbid condition in patients with chronic kidney disease (CKD) and is associated with many complications, mortality, and progression of CKD. Previous studies have not drawn a clear conclusion about the anti-inflammatory effects of statins in CKD. This meta-analysis is aimed at assessing the anti-inflammatory effects of statins therapy in patients with CKD. Methods. A comprehensive literature search was conducted in these databases (Medline, Embase, Cochrane library, and clinical trials) to identify the randomized controlled trials that assess the anti-inflammatory effects of statins. Subgroup, sensitivity, and trim-and-fill analysis were conducted to determine the robustness of pooled results of the primary outcome. Results. 25 eligible studies with 7921 participants were included in this meta-analysis. The present study showed that statins therapy was associated with a decreased C-reactive protein (CRP) (-2.06 mg/L; 95% CI: -2.85 to -1.27, p < 0.01). Subgroup, sensitivity, and trim-and-fill analysis showed that the pooled results of CPR were stable. Conclusion. This meta-analysis demonstrates that statins supplementation has anti-inflammatory effects in patients with CKD. Statins exert an anti-inflammatory effect that is clinically important in improving complications, reducing mortality, and slowing progression in CKD. We believe that the benefits of statins to CKD are partly due to their anti-inflammatory effects. However, stains usually are prescribed in the CKD patients with dyslipidemia, whether statins can reduce inflammation in CKD patients with normal serum lipid needed to explore in the future. Therefore, we suggest that randomized clinical trials need to assess the effect of statins in CKD patients with normal serum lipid. Whether statins can be prescribed for aiming to inhibit inflammation in CKD also needed further study. Trial Registration. The study protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO); registration number: CRD42022310334. [ABSTRACT FROM AUTHOR]

Background. Mongolian medicine is a systematic theoretical system, which is based on the balance among Heyi, Xila, and Badagan. However, the underlying mechanisms remain unclear. This study aimed to explore the characteristics of intestinal microbiota and metabolites in different rat models of Mongolian medicine. Methods. After establishing rat models of Heyi, Xila, and Badagan, we integrated 16S rRNA gene sequencing and metabolomics. Results. Heyi, Xila, and Badagan rats had significantly altered intestinal microbial composition compared with rats in the MCK group. They showed 11, 18, and 8 significantly differential bacterial biomarkers and 22, 11, and 15 differential metabolites, respectively. The glucosinolate biosynthesis pathway was enriched only in Heyi rats; the biosynthesis of phenylpropanoids pathway and phenylpropanoid biosynthesis pathway were enriched only in Xila rats; the isoflavonoid biosynthesis pathway, the glycine, serine, and threonine metabolism pathway, and the arginine and proline metabolism pathway were enriched only in Badagan rats. Conclusions. The intestinal microbiota, metabolites, and metabolic pathways significantly differed among Heyi, Xila, and Badagan rats compared with control group rats. [ABSTRACT FROM AUTHOR]

It is aimed at investigating the changes of serum soluble programmed death-ligand 1 (sPD-L1) expression level in nonsmall cell lung cancer (NSCLC) before and after radiotherapy, the correlation of PD-L1, PD-1, and proteins of Akt (protein kinase B), mTOR, and HIF-1α, and the molecular mechanism of the PD-1/PD-L1 pathway in the development of NSCLS. A total of 126 NSCLC patients receiving radiotherapy in Liaoning Cancer Hospital from September 2018 to September 2019 were selected as the observation group, and another 58 healthy volunteers were selected as the control group. NSCLC patients were divided into group A (stage I-II, stereotactic radiotherapy) and group B (stage III, intensity-modulated radiation therapy) according to the cancer stage. The efficacy of radiotherapy was evaluated, and sPD-L1 expression was detected by ELISA. The immunohistochemical staining was adopted to detect protein expressions of Akt, mTOR, and HIF-1α in NSCLC tissues. The correlation between their expression and expression of PD-L1 and PD-1 was analyzed. The results showed that the overall response rate (ORR) of group A was 89.29%, the clinical benefit response (CBR) was 96.43%, the median survival time (MST) was 25 months, and the survival rate within three years was 72.56%. In group B, the ORR was 70.41%, the CBR was 97.96%, the MST was 18 months, and the survival rate within three years was 34.67%. Comparison of overall serum sPD-L1 expression in the control group, group A, and group B and between groups before radiotherapy was statistically significant (P < 0.01). After radiotherapy, serum sPD-L1 expression in group A and group B decreased compared with that before radiotherapy (P < 0.01). Among NSCLC patients, the positive expression rate of Akt, mTOR, and HIF-1α was 71.32%, 41.26%, and 80.65%, respectively. PD-L1 expression and Akt, mTOR, and HIF-1α expression showed a significant correlation. PD1 expression and Akt, mTOR, and HIF-1α expression also showed a significant correlation. It indicated that the expression level of sPD-L1 in NSCLC patients was higher than that in normal subjects, but the expression level of sPD-L1 was decreased after radiotherapy. PD-1/PD-L1 may play important roles in NSCLC procession through the Akt/mTOR and HIF-1α pathway. [ABSTRACT FROM AUTHOR]

We tracked the motor skill development of young children aged 3–6 years and investigated the influence of middle-income home environment on the development of motor skill. 268 children were selected from kindergartens in Beijing. The Test of Gross Motor Development (TGMD) tool was used to test the development of locomotor and object-control skills (LS and OS), and a survey of children's behaviour and home environment was conducted. During the follow-up, the LS and OS of children aged 3–6 years continued to grow, with an annual growth rate of 20% and 30%. Five LS indicators and two OS indicators were significantly higher in the 3–4-year group than in the 4–5 and 5–6-year groups (p < 0.01). The age-sex trend model showed that girls' locomotor skill developed at a significantly higher rate than that of boys (β = 6.3004 and 4.6782, p < 0.001). Three-year-old boys performed significantly better than girls on object-control motor skill (p < 0.05). Factors affecting the rate of children's motor skill development in middle-income families included the frequency of playing with friends (β = 0.133 , p = 0.032) and the frequency of bicycling, skateboarding, dancing, running, and jumping (β = 0.041 , p = 0.042). Family income, parents' education level, and family activity area did not significantly affect the growth rate of motor skills. For middle-income families, the improvement of material environment at home like more playing spaces and toys did not speed up the motor development, while more opportunities to play with friends and engage in a variety of sports activities could promote children's motor skill development.

Activation of blood coagulation contributes to cancer progression. Tissue factor pathway inhibitor-1 (TFPI-1) is the main inhibitor of extrinsic coagulation pathway. The aim of this study is to assess the predicting significance of TFPI-1 for thrombotic complication and metastasis in lung cancer patients. Total of 188 non-small cell lung cancer (NSCLC) patients were included in this study. Plasma TFPI-1, D-dimer (D-D), antithrombin (AT), Fibrinogen (Fbg), and coagulating factor VIII activity (FVIII:C) were measured. In NSCLC patients, significantly decreased TFPI-1 and AT and increased D-D, Fbg, and FVIII:C levels were observed, and there was a significant correlation between TFPI-1 and other hemostatic parameters (P<0.001, resp.). NSCLC patients with deep venous thrombosis (DVT) or metastasis had significantly lower TFPI-1 levels than those without DVT or metastasis (P<0.01, resp.). Multivariate regression revealed that TFPI-1 acted as a predictor for DVT or tumor metastasis in NSCLC patients [OR: 4.15 or 3.28, P<0.05, resp.]. The area under ROC curve of TFPI-1 was 0.905 (95% CI, 0.842~0.967) or 0.828 (95% CI, 0.742~0.915) for predicting DVT or metastasis (P<0.001, resp.). The optimal point of TFPI-1 was 57.7 or 54.3 ng/mL for predicting DVT or metastasis, respectively. Combination of TFPI-1 and D-D measurements can improve the predicting power for DVT or metastasis in NSCLC patients. Our findings suggested that TFPI-1 was a valuable predictor of DVT and tumor metastasis in NSCLC patients. [ABSTRACT FROM AUTHOR]
