The molecular mechanisms underlying the develop-ment and metastasis of prostate cancer remain elusive.This comprehensive review delves into the intricate role of cofilin,an actin-binding protein,in the pathogenesis and progression of prostate cancer.Cofilin is a significant protein in cytoskeletal dynamics,and any dysregulation may result in the morphological changes in normal cells and the invasion and metastasis of tumor cells.Research has revealed that the activity of cofilin is regula-ted by various mechanisms,including phosphorylation/dephos-phorylation and interactions with other molecules.Moreover,this review discusses promising therapeutic interventions,such as co-filin inhibitors and gene therapy,which have demonstrated effica-cy in preclinical models.The challenge of clinically preventing the transition to castration-resistant prostate cancer and tumor metastasis is widely recognized,necessitating the development of precise drug treatments and biomarker identification.As a key regulatory protein,cofilin provides a more comprehensive refer-ence for the prevention and treatment of prostate diseases.

Trimethylamine N-oxide(TMAO), a metabolite of gut microbiota, is closely associated with chronic kidney disease(CKD). It can aggravate the kidney injury and promote the occurrence of complications of CKD mainly by inducing renal fibroblast activation, vascular endothelial inflammation, macrophage foaming, platelet hyperreactivity, and inhibition of reverse cholesterol transport. Thus it is of great significance for clinical treatment of CKD to regulate circulating TMAO and alleviate its induced body damage. Currently, therapeutic strategies for TMAO regulation include dietary structure adjustment, lifestyle intervention, intestinal microflora regulation, and inhibition of intestinal trimethylamine synthesis and liver trimethylamine oxidation. Chinese medicinal herbs have the clinical advantage of multi-component and multi-target effects, and application of traditional Chinese medicine(TCM) to synergistically regulating TMAO and improving CKD via multiple pathways has broad prospects. This study systematically reviewed the clinical relevance and mechanism of TMAO in aggravating CKD renal function deterioration and complication progression. In addition, the effect and mechanism of TCM in improving TMAO-induced kidney injury, cardiovascular disease, hyperlipidemia, thrombosis and osteoporosis were summarized. The results provided a theoretical basis for TCM in attenuating gut microbiota-derived metabolite TMAO and improving CKD, as well as a basis and direction for in-depth clinical development and mechanism research in the future.

Objective To investigate the relationship between exon 11 CAG triplet nucleotide repeats ([CAG]n) of myocyte enhancer binding factor-2A (MEF2A ) polymorphisms and ischemic stroke caused by large artery atherosclerosis (LAA). Methods Two hundred and five patients with first onset ischemic stroke caused by LAA, admitted to our hospital from June 2010 to December 2014, and 192 healthy controls were chosen in our study. The polymorphisms of exons 11 of MEF2A gene were genotyped by polymerase chain reaction-sequence-based typing (PCR-SBT). The relation of ischemic stroke caused by LAA with polymorphisms of (CAG)n was analyzed. Results Different (CAG)n alleles could be detected, with repeated sequences of 9-11. Frequencies for the different (CAG)n alleles in exon 11 CAG of MEF2A gene were not the same between the ischemic stroke patients and the controls (χ2=8.547, P=0.036). The distribution frequency of the (CAG)9 allele in the ischemic stroke group was significantly higher than that in the control group (χ2=6.650, P=0.010). Logistic regression analysis indicated that systolic pressure and (CAG)9 (OR=1.401, P=0.017, 95％CI: 1.063-1.847) were the independent risk factors of acute ischemic stroke caused by LAA. Conclusion The (CAG)n polymorphisms may be associated with ischemic stroke caused by LAA and the (CAG)9 allele may be one of the genetic susceptibility factors for this subtype of stroke.

Dietary pattern has been revealed to be associated with metabolic syndrome. However, the association was not well documented in Chinese due to the complexity of Chinese foods. We mainly assessed the dietary patterns and examined their effects on metabolic syndrome among Chinese adults. Four dietary patterns including 'Refined Grains & Vegetables' Pattern, 'Dairy & Eggs' Pattern, 'Organ Meat & Poultry' Pattern, and 'Coarse Grains & Beans' Pattern were extracted. 'Dairy & Eggs' Pattern was associated with a decreased odds of metabolic syndrome in women, and 'Coarse Grains & Beans' Pattern was associated with a decreased odds of hypertension in men. These results provided a scientific basis for future research and dietary guideline perfection.

Objective To evaluate the application of “OmniView”, a new three-dimensional ultrasound technology, in displaying the fetal palate. Methods The three-dimensional volume data was acquired from 100 normal fetuses, analysed by OmniView technology with the facial midsagittal plane as the starting plane. The imaging of fetal palate was obtained in axial plane (through maxilla, oral cleft), coronal plane, oblique coronal plane (through piriform aperture, oral cleft, submental triangle), and the palate′s curved plane tiled imaging by drawing the anatomical lines on referenced sagittal plane (facial midsagittal plane). The volumes of ifve fetuses with cleft lip and palate were obtained and analysed by the same technology. Results The volume dataset of 91 (91.0%, 91/100) normal fetuses were acquired successfully, and analyzed by OmniView technology, the results of 91 normal fetal palate in different plane were: (1) In axial plane through maxilla, the visualization of alveolar process bow was 91 (100%, 91/91). It was shown as“C”shaped arcuate structure, the anechoic structure of alveolar socket could be seen on the bow, and the ifrst 6 alveolar sockets were displayed clearly. The visualization number of hard palate was 91 (100%, 91/91), it was shown as hyperechoic lfake between two sides of alveolar bones. In axial plane through oral cleft, the visualization number of soft palate was 81 (89.0%, 81/91), it was shown as a strip of soft tissue echo band. (2) In coronal plane, the visualization number of hard palate was 91 (100%, 91/91), it was shown as a strip of hyperechoic band and separated the oral and nasal cavity. (3) In oblique coronal plane through piriform aperture, the visualization number of hard palate was 91 (100%, 91/91), it was shown as a short strip of hyperechoic band. In oblique coronal plane through oral cleft, the visualization number of hard palate was 91 (100%, 91/91). In oblique coronal plane through submental triangle, the visualization number of hard palate was 91 (100%, 91/91). In the above two planes, the hard palate was shown as a strip of hyperechoic band, due to acoustic shadow behind the hard palate, the nasal cavity and nasal septum above the hard palate couldn’t be displayed. (4) In oblique coronal plane through piriform aperture, the visualization number of soft palate was 81 (89.0%, 81/91). The visualization number of uvula was 25 (27.5%, 25/91). The soft palate was shown as a lfake of soft tissue echo behind the hard palate, and the uvula was shown as papillary protrusions on the edge of the soft palate in the midline. In oblique coronal plane through oral cleft, the visualization number of soft palate was 81 (89.0%, 81/91). In oblique coronal plane through submental triangle, the visualization number of soft palate was 81 (89.0%, 81/91). In the above two planes, the soft palate was shown as a strip of soft tissue echo band, the soft tissue echo of fetal tongue was in the lower front of soft palate, and the anechoic region of nasopharynx was superior behind the soft palate. (5) In the curved plane tiled imaging of palate, the visualization number of alveolar process bow (primary palate) was 91 (100%, 91/91). The visualization number of hard palate was 91 (100%, 91/91). The visualization number of soft palate was 81 (89.0%, 81/91). the visualization number of uvula was 25 (27.5%, 25/91), the planar panorama of alveolar process bow, hard palate and soft palate could be visualized intuitively, the alveolar arch and hard palate were shown as bone-like hyperecho, and the soft palate was shown as soft tissue hypoecho. In iffteen cases′volume involved cleft lip and palate, all five cases of malformations were detected through three-dimensional data analysis, the position and range of the cleft palate could also be conifrm. Abnormal fetuses were all veriifed after induction of labor. Conclusions By three-dimensional ultrasound technology-“OmniView”, the axial and coronal plane of fetal palate could be obtained easily which was dififcult by two-dimensional ultrasound, and the special oblique coronal plane of secondary palate could be displayed easily. The panorama of the palate could be visualized intuitively though curved plane tiled imaging by drawing a line tracking the structure of the palate. This technology could simplify the ultrasound examination procedure of the fetal palate, reduce the operators′skill-dependence, and quickly evaluated the integrity of the fetal primary palate and secondary palate. For the cleft lip fetus, this technology can determine whether the cleft palate exist or not, together with their position and range.
