Objective To investigate the expression and clinical pathological significance of PIWI-interacting RNA-47851 (piR-47851) in gastric adenocarcinoma and its influence on proliferation. Methods The expression of piR-47851 was detected in 79 gastric adenocarcinoma tissues by real time fluorescence quantitative polymerase chain reaction (qRT-PCR), and the correlation of piR-47851 expression level and clinical features with survival and prognosis were analyzed. The effect of piR-47851 on proliferation activity of gastric cancer cells was observed by cell proliferation experiments. Informatics websites were used to predict the downstream target genes of piR-47851. The wild-type and mutant plasmids for the 3'untranslated region (UTR) of MAPK1 gene were established, and a dual luciferase reporting system was used to verify that piR-47851 binded to the 3'UTR of MAPK1 gene, thereby inhibiting MAPK1 protein synthesis. The effect of overexpression/silencing of piR-47851 on MAPK1 expression level was examined through qRT-PCR experiment. Rescue experiment was used to confirm the direct regulatory effect of piR-47851 on MAPK1 and explore the effect of piR-47851/MAPK1 on the proliferation of gastric cancer cells. The effect of reduced piR-47851 expression on the volume and weight of transplanted tumors was observed in nude mice by xenograft tumor experiments; the effect of reduced piR-47851 expression on the cell proliferation activity of xenograft tumors was observed by Ki-67 staining. Results The qRT-PCR experiment result showed that the expression level of piR-47851 in 79 gastric adenocarcinoma tissues was significantly higher than that in normal gastric tissues adjacent to the cancer (P < 0.05). The expression level of piR-47851 was significantly correlated with tumor size, degree of differentiation, and survival prognosis (P < 0.05). Bioinformatics suggested that there was a complementary binding site between piR-47851 and MAPK1 gene 3'UTR. The dual luciferase reporter gene experiment showed that piR-47851 was able to significantly inhibit fluorescence enzyme activity in the MAPK1 wild-type transfection group, while this inhibitory effect was not observed in the MAPK1 mutant group. The CCK-8 proliferation activity experiment showed that overexpression of piR-47851 was able to significantly increase the proliferation activity of gastric cancer cells; after reducing piR-47851, the proliferation activity of cells decreased significantly (P < 0.05). Rescue experiment indicated that after changing the expression of piR-47851 and (or) MAPK1 and then detecting the expression level of MAPK1 by qRT-PCR, the MAPK1 could be regulated by piR-47851. Overexpression of MAPK1 could functionally reduce the proliferation promoting effect of piR-47851 on gastric cancer cells, while reducing MAPK1 expression could further enhance the proliferation activity of gastric cancer cells. In xenograft tumor experiments, reducing the expression of piR-47851 significantly resulted in smaller tumor growth volume and weight (P < 0.05). The proliferation index Ki-67 staining showed that the number of proliferative active cells in the reduced piR-47851 expression group was significantly lower than that in the control group (P < 0.05), which further validated the promotional effect of piR-47851 on cell proliferation. Conclusion The expression level of piR-47851 is increased in gastric adenocarcinoma tissues, which is closely related with tumor size and survival prognosis. The piR-47851 downregulates MAPK1 protein expression by binding to the 3'UTR of MAPK1, thereby promoting the proliferation of gastric cancer cells.

Objective: To investigate the potential relationship between sensory characteristics and gray matter volumes in children with autism spectrum disorders (ASD), to provide a basis for the diagnosis and treatment of children with ASD. Methods: A total of 40 ASD children who were treated or recovered in Xi an medical institutions and 16 typically developing (TD) children who were from several kindergatens in Xi an were invited for participation. Sensory characteristics were evaluated by the sensory processing and self regulation checklist, 3D structural brain images were obtained with TIWI, and gray matter volumes were analyzed by voxel based morphometry. Sensory characteristics and gray matter volumes were compared between groups and the relationship between sensory characteristics and different gray matter volumes were analyzed. Results: The scores of auditory, visual, tactile, sensory processing ability and sensory under responsivity in the ASD group were lower than those in the TD group ( Z/t =-2.63, -2.57 , -3.11, -2.19, -3.83, P <0.05). Gray matter volumes in nine brain regions increased in the ASD group compared to the TD group, including the left and right posterior inferior lobe, right parahippocamal gyrus, left insula, left media frontal gyrus, left superion occipital gyrus, right superion occipital gyrus, right superion parietal lobe, and right posterion central gyrus ( t =3.53, 3.69 , 3.37, 3.86, 3.61, 3.37, 4.04, 3.38, 3.16, P <0.01). In the ASD group, the scores of visual, vestibular, proprioceptive, sensory processing ability, sensory seeking behavior and sensory over responsivity were negatively correlated with gray matter volumes of left superior occipital gyrus ( r =-0.36, -0.40, -0.39, -0.36, -0.40, -0.36), and the scores of visual, vestibular, and sensory over responsivity were negatively correlated with gray matter volumes of the right superior parietal lobule ( r =-0.36, -0.50, -0.42)( P <0.05). Conclusion The presence of paresthesia in children with ASD is associated with gray matter volumes of the left superior occipital gyrus and right superior parietal lobule.

Cornus officinalis,a medicinal and edible plant known for its liver-nourishing properties,has shown promise in inhibiting the activation of hepatic stellate cells(HSCs),crucial indicators of hepatic fibrosis,especially when processed by high pressure wine steaming(HPWS).Herein,this study aims to investigate the regulatory effects of cornus officinalis,both in its raw and HPWS forms,on inflammation and apoptosis in liver fibrosis and their underlying mechanisms.In vivo liver fibrosis models were established by subcutaneous injection of CCl4,while in vitro HSCs were exposed to transforming growth factor-β(TGF-β).These findings demonstrated that cornus officinalis with HPWS conspicuously ameliorated his-topathological injury,reduced the release of proinflammatory factors,and decreased collagen deposition in CCl4-induced rats compared to its raw form.Utilizing ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometer(UHPLC-QTOF-MS)combined with network analysis,we identified that the pharmacological effects of the changed components of cornus officinalis before and after HPWS,primarily centered on the adenosine phosphate(AMP)-activated protein kinase(AMPK)pathway.Of note,cornus officinalis activated AMPK and sirtuin 3(SIRT3),promoting the apoptosis of activated HSCs through the caspase cascade by regulating caspase3,caspase6 and caspase9.small interfering RNA(siRNA)experiments showed that cornus officinalis could regulate AMPK activity and its mediated-apoptosis through SIRT3.In conclusion,cornus officinalis exhibited the ability to reduce inflammation and apoptosis,with the SIRT3-AMPK signaling pathway identified as a potential mecha-nism underlying the synergistic effect of cornus officinalis with HPWS on anti-liver fibrosis.

Objective:To investigate an accurate and quantitative method to measure the eyeball morphological parameters of guinea pigs through a method that combines programmed digital techniques and mathematical geometric principles.Methods:Twenty-two three-week-old clean-grade male tricolor guinea pigs were selected and sacrificed by anesthesia overdose.Eyeballs were enucleated.The horizontal and sagittal images of the eyeball were taken with the high-speed photographic model of 13 million pixels macro meter, and the pictures were imported into pycharm programming software.Using the pre-written analysis program of Python 3.9, the conversion coefficient between the photo pixel and the actual length was obtained by a scale, and then the corneal surface was fitted by arc fitting and conic curve fitting.The results of arc fitting were converted to calculate the corneal radius of curvature.The corneal eccentricity was calculated according to the general conic equation (Ax 2+ Bxy+ Cy 2+ Dx+ Ey+ F=0). The corneal asphericity was evaluated by curve fitting between the central 3-mm and the whole cornea.The use and care of the animals complied with Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.The study protocol was approved by the Ethics Committee of Shanghai Public Health Clinical Center (No.2022-A009-01). Results:The digital method of Python programming can show the corneal contour of guinea pigs completely and clearly.In the transverse plane, there was no significant difference in the corneal curvature measurements among the digital fitting in central 3-mm cornea, digital fitting in whole cornea and curvature meter ( F=1.693, P=0.190). In the sagittal plane, there was a significant difference in the corneal curvature measurements among the three methods ( F=3.500, P=0.030), and the corneal curvature measurements of the whole cornea measured by the curvature meter were significantly greater than those measured by the digital fitting ( P<0.05). There was no statistical significance in the measurements of corneal curvature radius among the three methods in the transverse plane and the sagittal plane ( F=1.817, P=0.170; F=2.050, P=0.133). The horizontal and sagittal corneal eccentricity measured by digital fitting in central 3-mm cornea were 0.55±0.15 and 0.53±0.17, which were lower than 0.66±0.10 and 0.64±0.14 measured by digital fitting in whole cornea, and the differences were statistically significant ( t=-4.860, -5.210; both at P<0.01). Conclusions:It is feasible to use Python programming digital method to measure the corneal curvature and eccentricity of guinea pigs.
