M. mulatta, M. thibetana and M. assamensis have a part of sympatry in distribution areas and closed relationships in phylogeny, but there also exist certain differences among them in the morphology and function of skeleton. In recent years, on their locomotion and adaptive behaviors, the different viewpoints were suggested by many authors. The comparison of distal articular surface of humerus in these species were carried out in this paper. The major results based on 24 humerus including 48 sides are as follows:1. The results of the discriminant analysis suggest that the features and structures of humeral distal articulation of M. thibetana is similar to that of M. assamensis than that of M. mulatta.2. The relative width of articulation (AFT), olecranon fossa (OFW) and internal epicondyle (MEW), and the relative length of trochlea (THL) play more important rule to distinguish the three species of macaques. The. first discriminate function is: F1=13.64MEW-15.57ATF+23.500FW+14.09THL-9.63.3. The characters on distal articulation of humerus of the three species of monkeys differ evidently from the apes.4. The results of principal component analysis show that the locomotion of M. mulatta is similar to Presbytes obscurus, Hylobates and M. nemestrina, and it seems that they are more adaptive to arboreal movement than that in M. thibetana and M. assamensis based on the osteological features and functional morphology of the distal articular surface of humerus.

PURPOSE: Long non-coding RNA (lncRNA) nuclear paraspeckle assembly transcript 1 (NEAT1) has been implicated as an oncogene in the development and progression of osteosarcoma. This study aims to explore the mechanism of NEAT1 in osteosarcoma. MATERIALS AND METHODS: Expressions of NEAT1 and miR-194 in osteosarcoma tissues and cells were detected by quantitative real-time PCR. The effects of NEAT1 knockdown or miR-194 overexpression on cell proliferation, invasion, and apoptosis were determined by 3-[4, 5-dimethylthiazol-2-yl]-2, 5 diphenyl tetrazolium bromide (MTT) assay, transwell invasive assay, and flow cytometry analysis, respectively. Luciferase reporter assay was performed to observe the possible interaction between NEAT1 and miR-194. RESULTS: NEAT1 was upregulated and miR-194 was downregulated in osteosarcoma tissues and cells. Knockdown of NEAT1 or overexpression of miR-194 suppressed proliferation and invasion and induced apoptosis of osteosarcoma cells in vitro. Luciferase reporter assay validated that NEAT1 could interact with miR-194 and negatively modulated its expression. Furthermore, inhibition of miR-194 reversed the suppression of proliferation and invasion and the promotion of apoptosis induced by NEAT1 depletion in osteosarcoma cells. CONCLUSION: Knockdown of NEAT1 suppressed proliferation and invasion and induced apoptosis in osteosarcoma cells by inhibiting miR-194 expression.

Objective:To investigate the effects of blood glucose target management combined with early hemoperfusion on inflammatory reaction and stress in patients with hyperlipidemic acute pancreatitis (HL-AP).Methods:A prospective cohort study was used. One hundred and fifty-nine patients with HL-AP from September 2019 to September 2022 in Zhoukou Central Hospital Affiliated to Xinxiang Medical University were selected. The patients were divided into group A, B and C by random number table method with 53 cases in each group. All patients were given routine treatment. On this basis, the patients in group A were given blood glucose target management, the patients in group B were given early hemoperfusion, and the patients in group C were given blood glucose target management combined with early hemoperfusion. Before treatment and 7 d after treatment, the inflammatory factors (including interleukin-10, IL-10; interleukin-18, IL-18; tumor necrosis factor-α, TNF-α; soluble intercellular adhesion molecule-1, sICAM-1; procalcitonin, PCT; high mobility group protein B1, HMGB1; nuclear factor-κB p65, NF-κB p65), stress indexes (including lipid hydrogen peroxide, LHP; advanced protein oxidation products, AOPPs; catalase, CAT; glutathione peroxidase, GSH-Px; epinephrine, E and cortisol), intestinal mucosal barrier indexes (including D-lactate; diamine oxidase, DAO; endotoxin) and hemorheological indexes (including platelet adhesion rate, plasma specific viscosity, whole blood specific viscosity high shear and thrombus length) were detected. The recovery indexes (urinary amylase recovery time, bowel sound recovery time, exhaust recovery time, abdominal pain relief time and hospitalization time), adverse reactions and curative effect were recorded.Results:There were no statistical differences in the detection indexes before treatment among three groups ( P>0.05). Seven days after treatment, the IL-10, CAT and GSH-Px in group C were significantly higher than those in group A and group B. The IL-18, NF-κB p65, TNF-α, sICAM-1, PCT, HMGB1, LHP, AOPPs, E, cortisol, D-lactic acid, DAO and endotoxin were significantly lower than those in group A and group B with statistical differences ( P<0.05), but no statistical differences in the indexes between group A and group B ( P>0.05). Seven days after treatment, the platelet adhesion rate, plasma specific viscosity, whole blood specific viscosity high shear and thrombus length in group C were significantly lower than those in group A and group B, while the indexes in group B were significantly lower than those in group A, with statistical differences ( P<0.05). The urinary amylase recovery time, bowel sound recovery time, exhaust recovery time, abdominal pain relief time and hospitalization time in group C were significantly shorter than those in group A and group B: (5.73 ± 0.64) d vs. (7.49 ± 0.89) and (7.26 ± 0.85) d, (2.45 ± 0.31) d vs. (5.76 ± 0.73) and (5.83 ± 0.79) d, (2.69 ± 0.42) d vs. (6.04 ± 0.81) and (6.07 ± 0.82) d, (1.87 ± 0.29) d vs. (3.58 ± 0.45) and (3.65 ± 0.46) d, (15.24 ± 1.76) d vs. (18.61 ± 2.29) and (18.78 ± 2.34) d, with statistical differences ( P<0.05), but no statistical differences in the indexes between group A and group B ( P>0.05). The total effective rate in group C was significantly higher than that in group A and group B: 90.57% (48/53) vs. 67.92% (36/53) and 60.38% (32/53), with statistical difference ( P<0.05), but no statistical difference in the total effective rate between group A and group B ( P>0.05). There was no statistical difference in the incidence of adverse reactions among three groups ( P>0.05). Conclusions:The blood glucose target management combined with early hemoperfusion in the treatment of HL-AP can effectively reduce inflammatory reaction and stress state, protect intestinal mucosal barrier function, improve blood rheology, and promote recovery.

Objective:To explore the psychometric characteristics of the Chinese version of the health-related social capital scale.Methods:From March to May 2020, after the original scale was translated into Chinese following the Brislin improved translation model, 251 community-dwelling senior citizens aged 65 and above were selected by convenient sampling method. Data analysis was conducted using SPSS 22.0 and AMOS 22.0, including tests of significance, correlation analysis, exploratory factor analysis, and confirmatory factor analysis.Results:Exploratory factor analysis extracted three factors: social participation, social cohesion, and reciprocity, which accounted for a cumulative contribution rate of 61.72%. Confirmatory factor analysis showed that the three-factor model fitted well(χ 2/ df=1.22, RMSEA=0.04, CFI=0.98, GFI=0.93, IFI=0.98, TLI=0.97). Social capital was significantly correlated with perceived social support positively ( r=0.36, P<0.01), and with loneliness negatively ( r=-0.30, P<0.01). The three factors were significantly correlated with the total scale ( r=0.85, 0.50 and 0.52, respectively, all P<0.01). And correlations between the items of each factor were 0.24-0.55, 0.30-0.59, 0.44-0.70, respectively(all P<0.01). The Cronbach's α coefficients of the total scale and three factors were 0.74, 0.72, 0.65 and 0.62, respectively(all P<0.01), and their retest reliability were 0. 92, 0. 87, 0. 82 and 0. 96, respectively(all P<0.01). Conclusion:The Chinese version of health-related social capital scale conforms to the three-factor model with good reliability and validity, which can be used to assess the social capital status of community-dwelling older adults in China.
