The effect of the Ankle Pump Exercise (APE) counter system assisted ankle pump motion in patients after femoral neck fracture.

OBJECTIVE: To explore the effect of the Ankle Pump Exercise (APE) counter system on moderate to high-risk Venous thromboembolism (VTE) after femoral neck fracture surgery. METHODS: From June 2021 to June 2022, a total of 140 patients with moderate and high-risk VTE after femoral neck fracture surgery treated at the Department of Orthopedics of a tertiary hospital in Zhejiang were included and divided into observation (70 cases) and control (70 cases) groups according to whether APE counter system was used or not. The control group was given routine oral propaganda, and the observation group was given a comprehensive nursing intervention with APE counter system on the basis of the control group's treatment. The compliance rates of the two groups on the postoperative 3st, 5rd, and 7th days were compared. Moreover, the General self-efficacy scale (GSES) was used to evaluate self-efficacy before and after exercise. RESULTS: The compliance rates of the control group and the observation group on the postoperative 3st, 5rd, and 7th days were 74.3% vs. 85.7%, 67.1% vs. 85.7%, and 61.4% vs. 82.9%. On the 5rd and 7th days, the compliance of the observation group was obviously higher than that of the control group. Moreover, the mean postoperative GSES score was also significantly higher than that in the control group (23.20 ± 3.516 vs. 25.31 ± 4.583, P < 0.05, values are expressed in mean ± standard). CONCLUSION: APE counter system can significantly improve the compliance and self-efficacy of patients with moderate and high-risk VTE after lower limb fracture surgery.

Meta-analysis of the effects of CYP3A5*3 gene polymorphisms on tacrolimus blood concentration and effectiveness in Chinese patients with membranous nephropathy.

Objective: The study aimed to systematically evaluate the relationship between CYP3A5*3 gene polymorphisms and the blood concentration and effectiveness of tacrolimus (TAC) in patients with membranous nephropathy (MN). Methods: PubMed, Cochrane Library, Embase, Web of Science, China Biomedical, China National Knowledge Infrastructure, Wanfang, Vipshop, ReadShow, Clinical Trials Registry, and other databases were searched. Studies on the relationship between CYP3A5*3 gene polymorphism and TAC blood concentration in MN patients were collected, and meta-analysis was performed using Stata 16 software. Results: A total of eight publications were included in the study, including 498 MN patients. CYP3A5*3 gene polymorphisms are associated with tacrolimus blood levels in patients with MN. The results of the relationship between CYP3A5*3 genotype polymorphisms and tacrolimus blood trough concentrations of the AA + AG genotype were lower than those of the GG genotype at ≤1 month [WMD = -2.08, 95% CI (-2.57, -1.59), p < 0.001] and 1-6 months [WMD = -0.63, 95% CI (-0.98, -0.27), p < 0.001]; however, they were not statistically significant at ≥6 months (p = 0.211). Furthermore, the subgroup analysis revealed that the dose-adjusted concentration of tacrolimus (C0/D) of the AA + AG genotype was lower than that of the GG genotype at ≤1 month [SMD = -1.93, 95% CI (-2.79, -1.08), p < 0.001], 1-6 months [SMD = -2.25, 95% CI (-2.71, -1.79), p < 0.001], and ≥6 months [SMD = -2.36, 95% CI (-2.86, -1.86), p < 0.001]. In addition, there was no statistically significant difference in effectiveness between the two groups at 3, 6, and 12 months of TAC administration (p > 0.05). Conclusion: Serum TAC concentrations in MN patients were correlated with CYP3A5*3 genotype polymorphisms. Detection of the CYP3A5*3 genotype before the administration of TAC may provide some clinical value for optimizing the treatment of MN patients.

MicroRNA-322 Attenuates Cartilage Matrix Degradation in Osteoarthritis via Direct Suppression of TRAF3.

OBJECTIVE: Osteoarthritis (OA) is a degenerative joint disease. A growing number of studies have shown that microRNAs (miRNAs) play an important role in the pathogenesis of OA. However, the specific function of miR-322 in OA is unknown. This study was aimed to explore the ability of miR-322 in the cartilage matrix degradation and the mechanism in OA. METHODS: Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was performed to detect miR-322 expression in cartilage and OA-associated gene expression in chondrocytes treated with miR-322 mimics/inhibitors or interleukin (IL)-1ß, respectively. The targets of miR-322 were analyzed using software and the luciferase reporter experiment. In vivo, intra-articular injection of miR-322 mimics was administered at the knee of DMM mice. After 12 weeks, the knee joints of mice were collected for histological analysis. RESULTS: The expression of miR-322 was decreased in knee cartilage of DMM mice and was significantly reduced by IL-1ß. miR-322 mimics inhibited IL-1ß-induced extracellular matrix degradation, as evidenced by higher expression of Col2α1 and Aggrecan, and lower expression of Adamts5, MMP3, and MMP13. In contrast, miR-322 inhibitor promoted extracellular matrix degradation of chondrocytes. TRAF3 was the predicted target of miR-322 from databases. Luciferase reporter assay verified the targeting relationship between miR-322 and TRAF3. The effect of miR-322 on extracellular matrix degradation was partially reversed by overexpression of TRAF3. In addition, H&E and Safranin-O fast green staining assays in OA mouse models showed that miR-322 mimics attenuated the progression of OA in vivo. CONCLUSIONS: miR-322 suppressed chondrocytes matrix degradation and alleviated OA cartilage injury via inhibition of the TRAF3.

Characterization of exosomes derived from IPEC-J2 treated with probiotic Bacillus amyloliquefaciens SC06 and its regulation of macrophage functions.

Probiotics can maintain or improve health by modulating the response of immune cells in the gastrointestinal tract. However, the mechanisms by which probiotics promote macrophage (Mφ) activity are poorly understood. Here, we evaluated exosomes derived from intestinal epithelial cells treated with Bacillus amyloliquefaciens SC06 (Ba) and investigated the regulation of Mφ phagocytosis, apoptosis, and polarization. We isolated two exosomes from intestinal porcine epithelial cell lines (IPEC-J2) with or without Ba-treatment, named Ba-Exo and Exo, respectively. They had typical sizes and a cup-shaped morphology, and their surfaces presented typical exosomes-associated proteins, including CD63, ALIX, and TSG101. Ba-Exo and Exo could entrer Mφ (3D4/21 cells) effectively. Moreover, an in vitro phagocytosis assay demonstrated that Ba-Exo can promote phagocytosis of Mφ. Similar to Exo, Ba-Exo had no effect on Mφ apoptosis. Furthermore, Ba-Exo significantly increased inducible nitric oxide synthase (iNOS), declined the expression of arginase 1 (Arg1) in Mφ, and stimulated Mφ polarization to M1. To explore the differences in the regulation of Mφ polarization between Ba-Exo and Exo, we performed reverse transcription quantitative polymerase chain reaction analysis of the small RNAs and found that miR-222 increased in the Ba-Exo group compared to that in the Exo group. These results provide a new perspective on the relationship between probiotics and intestinal immunity.

Potential Association Between Changes in Microbiota Level and Lung Diseases: A Meta-Analysis.

OBJECTIVE: Lung microbiota is increasingly implicated in multiple types of respiratory diseases. However, no study has drawn a consistent conclusion regarding the relationship between changes in the microbial community and lung diseases. This study verifies the association between microbiota level and lung diseases by performing a meta-analysis. METHODS: Literature databases, including PubMed, ISI Web of Science, Embase, Google Scholar, PMC, and CNKI, were used to collect related articles published before March 20, 2021. The standard mean deviation (SMD) and related 95% confidence intervals (CIs) were calculated using a random-effects model. Subgroup, sensitivity, and publication bias analyses were also conducted. RESULTS: Six studies, comprising 695 patients with lung diseases and 176 healthy individuals, were included in this meta-analysis. The results indicated that the microbiota level was higher in patients with lung diseases than in healthy individuals (SMD = 0.39, 95% CI = 0.22-0.55, I 2 = 91.5%, P < 0.01). Subgroup analysis based on country demonstrated that the microbiota level was significantly higher in Chinese (SMD = 1.90, 95% CI = 0.87-2.93, I 2 = 62.3%, P < 0.01) and Korean (SMD = 0.24, 95% CI = 0.13-0.35, I 2 = 78.7%, P < 0.01) patients with lung diseases. The microbiota level of patients with idiopathic pulmonary fibrosis (IPF) (SMD = 1.40, 95% CI = 0.42-2.38, I 2 = 97.3%, P = 0.005), chronic obstructive pulmonary disease (COPD) (SMD = 0.30, 95% CI = 0.09-0.50, I 2 = 83.9%, P = 0.004), and asthma (SMD = 0.19, 95% CI = 0.06-0.32, I 2 = 69.4%, P = 0.004) were significantly higher than those of the healthy group, whereas a lower microbiota level was found in patients with chronic hypersensitivity pneumonitis (CHP). The microbiota level significantly increased when the disease sample size was >50. Subgroup analysis based on different microbiota genera, indicated that Acinetobacter baumannii and Pseudomonas aeruginosa were significantly increased in COPD and asthma diseases. CONCLUSION: We observed that patients with IPF, COPD, and asthma had a higher microbiota level, whereas patients with CHP had a lower microbiota level compared to the healthy individuals. The level of A. baumannii and P. aeruginosa were significantly higher in patients with COPD and asthma, and thus represented as potential microbiota markers in the diagnosis and treatment of lung diseases.

Bis[(E)-4-bromo-2-(methoxy-imino-meth-yl)phenolato-κN,O]copper(II).

In the title centrosymmetric mononuclear copper(II) complex, [Cu(C(8)H(7)BrNO(2))(2)], the Cu(II) atom, lying on an inversion centre, is four-coordinated in a trans-CuN(2)O(2) square-planar geometry by two phenolate O atoms and two oxime N atoms from two symmetry-related N,O-bidentate oxime-type ligands. Inter-molecular C-H⋯O hydrogen bonds link neighbouring mol-ecules into a one-dimensional supra-molecular structure with an R(2) (2)(14) ring motif. This structure is further stabilized by π-π stacking inter-actions between adjacent benzene rings [centroid-centroid distance = 3.862 (1) Å].

3,3'-Bis(4-nitro-phen-yl)-1,1'-(p-phenyl-ene)dithio-urea dimethyl sulfoxide disolvate.

The asymmetric unit of the title compound, C(22)H(16)N(6)O(6)S(2)·2C(2)H(6)OS, consists of one half-mol-ecule of the centrosymmetric thiourea derivative and one molecule of dimethyl sulfoxide (DMSO). The carbonyl group forms an intra-molecular hydrogen bond with the NH group, creating a six-membered (C-N-C-N-H⋯O) ring. Two other N-H⋯O hydro-gen bonds link one mol-ecule of the thio-urea to two mol-ecules of DMSO.

N-(2-Chloro-benzo-yl)-N'-(3-pyrid-yl)thio-urea.

In the mol-ecule of the title compound, C(13)H(10)ClN(3)OS, the dihedral angles between the plane through the thio-urea group and the pyridine and benzene rings are 53.08 (3) and 87.12 (3)°, respectively. The mol-ecules are linked by inter-molecular N-H⋯N hydrogen-bonding inter-actions to form a supra-molecular chain structure along the a axis. An intra-mol-ecular N-H⋯O hydrogen bond is also present.
