OBJECTIVE
To study the anti-ulcerative colitis(UC) effect of Sargentodoxae Caulis and explore its mechanism.
METHODS
The UC mice model induced by dextran sodium sulfate was used to evaluate the anti-UC effect of Sargentodoxae Caulis. The ingredients of Sargentodoxae Caulis were obtained according to the CNKI and PubMed website, component targets were screened by SwissTargetPrediction database, GEO gene chip was used to extract UC differential genes, then a network of "ingredients-targets-disease" of the Sargentodoxae Caulis was constructed. After screening the core targets, protein interaction and cluster analysis, biological process and pathway enrichment analysis were performed, and the reliability of network analysis was preliminarily verified by molecular docking and literatures.
RESULTS
Sargentodoxae Caulis could significantly improve the disease activity index score, colon shortening and colonic histopathological changes of UC mice, and had a good anti-UC effect. The network analysis found that the core components of the anti-UC of Sargentodoxae Caulis include (+)-Dihydroxyurearetic acid, Isorhaponigenin and Pinosylvin, and 63 core targets, such as EGFR, STAT1 and LCK, regulating PI3K-Akt signal pathway and cancer proteoglycan and other related signal pathways of immune anti-inflammatory and anti-cancer, and it could affect the biological processes such as amino acid modification, kinase activity regulation, cell reaction and oxidative stress to treat UC. Molecular docking and literature showed that the constructed network had high reliability.
CONCLUSION
Sargentodoxae Caulis has a good anti-UC effect, and its mechanism may be closely related to the regulation of intestinal immune inflammation and cell proliferation, differentiation and migration. It has the characteristics of multi-component, multi-target and multi-way.

Objective:To explore the effect of combining hand-brain perception training with hand-brain motor training based on mirror neuron theory on the recovery of upper limb function after a stroke.Methods:A group of 105 stroke survivors with upper limb dysfunction were randomly divided into a hand-brain perception (HP) group, a hand-brain motor (HM) group, and a combination (C) group, each of 35. In addition to conventional rehabilitation treatment (including exercise therapy, occupational therapy and physical factor therapy), the HP and HM groups were given hand-brain perception training and hand-brain motor training respectively, while group C was provided with both. Before the intervention and after 4 weeks, the upper limb motor functioning of all of the participants was assessed using the simplified version of the Fugl-Meyer upper limb motor function scale (FMA-UE). Sensory functioning was quantified using the tactile Semmes Weinstein monofilament examination (SWME), and the modified Barthel index (MBI) was used to quantify the participants′ ability in the activities of daily living.Results:After the intervention the average FMA-UE, MBI and SWME scores of all three groups had improved significantly, with group C′s average FMA-UE and MBI scores significantly better than the other two groups′ averages. The average SWME score of group C was then significantly better than that of group HM.Conclusions:Hand-brain perception combined with hand-brain motor training based on mirror neuron theory can further promote the recovery of upper limb sensory and motor functioning of stroke survivors., Such therapy is worthy of clinical promotion and application.

BACKGROUND:
The switch/sucrose nonfermentable chromatin-remodeling (SWI/SNF) complex is a pivotal chromatin remodeling complex, and the genomic alterations (GAs) of the SWI/SNF complex are observed in several cancer types, correlating with multiple biological features of tumor cells. However, their role in liver metastasis of non-small cell lung cancer (NSCLC) remains unclear. Our study aims to investigate the role and potential mechanisms underlying NSCLC liver metastasis induced by the GAs of SWI/SNF complex.
METHODS:
The GAs of SWI/SNF complex in NSCLC cell lines (H1299, H23 and H460) were identified by whole-exome sequencing (WES). ARID1A knockout H1299 cell was constructed with the CRISPR/Cas9 technology. The mouse model of liver metastasis from NSCLC was established to simulate lung cancer liver metastasis and observe the metastasis rate under different gene mutation conditions. RNA sequencing and Western blot were conducted for differential gene expression analysis. Immunohistochemistry (IHC) analysis was used to assess protein expression levels of SWI/SNF-regulated target molecules in mouse liver metastases.
RESULTS:
WES analysis revealed intracellular gene mutations. The animal experiments demonstrated a correlation between the GAs of SWI/SNF complex and a higher liver metastasis rate in immunodeficient mice. Transcriptome sequencing and Western blot analysis showed upregulated expression of ALDH1A1 and APOBEC3B in SWI/SNF-mut cells, particularly in ARID1A-deficient H460 and H1299 sgARID1A cells. IHC staining of mouse liver metastases further demonstrated elevated expression of ALDH1A1 in the H460 and H1299 sgARID1A group.
CONCLUSIONS
This study underscores the critical role of the GAs of SWI/SNF complex, such as ARID1A and SMARCA4, in promoting liver metastasis of lung cancer cells. The GAs of SWI/SNF complex may promote liver-specific metastasis by upregulating ALDH1A1 and APOBEC3B expression, providing novel insights into the molecular mechanisms underlying lung cancer liver metastasis.

Klotho gene was originally discovered as an anti-aging gene, Klotho protein encoded by Klotho gene is expressed in multiple human tissues, and its most prominent function is the regulation of phosphate homeostasis. Klotho protein possesses various activities, including inhibition of multiple signaling pathways, reducing oxidative stress and suppressing inflammation, and these activities are associated with cancer. Klotho protein is discovered as a universal tumor suppressor, and its expression is associated with tumorigenesis and prognosis of patients. Lung cancer is the most common malignancy tumor, and it is the leading cause of cancer deaths worldwide because of its high incidence and mortality. This article summarizes the research progress of the role of Klotho on pathogenesis, therapeutic effect and prognosis in lung cancer, in order to provide new biomarker and target for diagnosis, treatment and prognosis of lung cancer.

BACKGROUND:
The fetal growth charts in widest use in China were published by Hadlock >35 years ago and were established on data from several hundred of American pregnant women. After that, >100 fetal growth charts were published around the world. We attempted to assess the impact of applying the long-standing Hadlock charts and other charts in a Chinese population and to compare their ability to predict newborn small for gestational age (SGA).
METHODS:
For this retrospective observational study, we reviewed all pregnant women ( n = 106,455) who booked prenatal care with ultrasound measurements for fetal biometry at the Shenzhen Maternity and Child Healthcare Hospital between 2012 and 2019. A fractional polynomial regression model was applied to generate Shenzhen fetal growth chart ranges for head circumference (HC), biparietal diameter (BPD), abdominal circumference (AC), and femur length (FL). The differences between Shenzhen charts and published charts were quantified by calculating the Z -score. The impact of applying these published charts was quantified by calculating the proportions of fetuses with biometric measurements below the 3rd centile of these charts. The sensitivity and area under the receiver operating characteristic curves of published charts to predict neonatal SGA (birthweight <10th centile) were assessed.
RESULTS:
Following selection, 169,980 scans of fetal biometry contributed by 41,032 pregnancies with reliable gestational age were analyzed. When using Hadlock references (<3rd centile), the proportions of small heads and short femurs were as high as 8.9% and 6.6% in late gestation, respectively. The INTERGROWTH-21st standards matched those of our observed curves better than other charts, in particular for fat-free biometry (HC and FL). When using AC<10th centile, all of these references were poor at predicting neonatal SGA.
CONCLUSIONS
Applying long-standing Hadlock references could misclassify a large proportion of fetuses as SGA. INTERGROWTH-21st standard appears to be a safe option in China. For fat-based biometry, AC, a reference based on the Chinese population is needed. In addition, when applying published charts, particular care should be taken due to the discrepancy of measurement methods.

Parthenogenetic embryos, created by activation and diploidization of oocytes, arrest at mid-gestation for defective paternal imprints, which impair placental development. Also, viable offspring has not been obtained without genetic manipulation from parthenogenetic embryonic stem cells (pESCs) derived from parthenogenetic embryos, presumably attributable to their aberrant imprinting. We show that an unlimited number of oocytes can be derived from pESCs and produce healthy offspring. Moreover, normal expression of imprinted genes is found in the germ cells and the mice. pESCs exhibited imprinting consistent with exclusively maternal lineage, and higher X-chromosome activation compared to female ESCs derived from the same mouse genetic background. pESCs differentiated into primordial germ cell-like cells (PGCLCs) and formed oocytes following in vivo transplantation into kidney capsule that produced fertile pups and reconstituted ovarian endocrine function. The transcriptome and methylation of imprinted and X-linked genes in pESC-PGCLCs closely resembled those of in vivo produced PGCs, consistent with efficient reprogramming of methylation and genomic imprinting. These results demonstrate that amplification of germ cells through parthenogenesis faithfully maintains maternal imprinting, offering a promising route for deriving functional oocytes and having potential in rebuilding ovarian endocrine function.
