Pan-colonic motility was studied under normal conditions with a novel capsule-style system. A single use telemetry capsule embedded with one pressure sensor was ingested by subjects. It is capable of transmitting colonic pressure wirelessly greater than 130 h. Time of capsule entering segmental colon was determined by ultrasonic detection for tracing the batteries in capsule. The ultrasonic electrodes were mounted on the surface of subjects' ileocecum, navel as well as the junction of left colon and rectosigmoid colon in sequence. They were identified by abdominal X-rays with radiopaque markers. The confirming X-rays showed all telemetry capsules were detected successfully when passing through the key points in colon. A total of 613 h of colorectal recording was obtained from 20 healthy subjects. When compared with the parameters in the time of waking, the number of contractions and the area under contractions were significantly (P<0.05) decreased during sleep (21 +/- 5 vs 15 +/- 4 h(-1); 463 +/- 54 vs 342 +/- 45 mmHg x s x min(-1)). The colonic motility exhibited significant regional variation in the circadian behavior, as well as in its response to waking and meal. The clinical study proved the reliability and non-invasiveness of the system. It may represent a useful tool for the study on physiology and pathology of colonic motor disorders.

Objective: To explore the effects of Buyang Huanwu decoction (BYHWD) on vascular neogenesis and hemorheological parameters following cervical spinal cord injury (SCI). Methods: An acute cervical SCI model was established using 84 female Sprague–Dawley rats. Functional recovery of the rats was evaluated using the forelimb locomotor scale score, forelimb grip strength test, and Basso-Beattie-Bresnahan score. The animals were subsequently euthanized at days 7 and 28 postoperatively. The gross morphology, neuronal survival, and myelin sheath in the injured area were evaluated using hematoxylin and eosin (HE), Nissl, and luxol fast blue (LFB) staining, respectively. Immunofluorescence staining was used to observe CD31 expression 7 days post-injury. Furthermore, the expression of CD31, neuronal nuclear protein (NeuN), and myelin basic protein (MBP) were evaluated 28 days post-injury. Additionally, vascular endothelial growth factor A (VEGFA) and VEGF receptor-2 (VEGFR-2) expression was evaluated using western blotting. Whole-blood viscosity, plasma viscosity, and red blood cell aggregation were measured using a hemorheometer. Results: From postoperative days 3–28, motor function in the BYHWD group began to recover considerably compared to the SCI group. BYHWD effectively restored spinal cord histopathology. In addition, the number of NeuN-positive cells, and fluorescence intensity of CD31at 7 and 28 days and MBP significantly increased in the BYHWD group compared with the SCI group (all P < .05). Moreover, this decoction significantly upregulated the expression of VEGFA and VEGFR-2 (all P < .05). BYHWD improved the hemorheology results (i.e., except erythrocyte aggregation index in the low-dose group), revealing statistically significant differences compared with the SCI group (all P < .05). Conclusion BYHWD effectively promoted angiogenesis, improved hemorheological parameters, and protected neurons and myelin sheaths, ultimately promoting the recovery of neurological function after cervical SCI in rats. These findings suggest that BYHWD promotes vascular neogenesis through the VEGFA/VEGFR-2 pathway.

Objective To systematically assess the diagnostic efficacy of circRNA in detecting CRC. Methods Eligible studies were obtained by searching the databases, such as PubMed, EMBASE, CNKI, etc. in line with the inclusion and exclusion criteria. Study quality and bias were judged by QUADAS-2 tool. The overall effect size, including pooled diagnostic parameters, was combined based on STATA 12.0 software. The causes of heterogeneity were investigated by conducting the subgroup, sensitivity and meta-regression analyses. Results We included 17 eligible studies which contained 1873 CRC cases and 1573 paired controls. For CRC detection, circRNA expression harbored a pooled sensitivity, specificity and AUC of 0.79 (95%CI: 0.76-0.81), 0.69 (95%CI: 0.64-0.73) and 0.81, respectively. Subgroup analysis showed that serum-derived circRNA testing (AUC=0.89, DOR=16.79) harbored higher diagnostic efficacy than plasma (AUC=0.79, DOR=7.08) and tissue (AUC=0.76, DOR=6.87); oncogenic circRNAs achieved higher diagnostic capacity in detecting CRC than the anti-cancer circRNAs (AUC: 0.81 vs. 0.76; DOR: 8.54 vs. 6.21); however, circRNA testing quantified based on GAPDH showed comparable diagnostic capacity with the overall pooled effect. Conclusion Abnormally-expressed circRNAs have relatively high diagnostic efficacy in diagnosing CRC and may be rated as auxiliary biomarkers for CRC detection.

Traditional Chinese patent medicines are widely used to treat stroke because it has good efficacy in the clinical environment.However,because of the lack of knowledge on traditional Chinese patent medicines,many Western physicians,who are accountable for the majority of clinical prescriptions for such medicine,are confused with the use of traditional Chinese patent medicines.Therefore,the aid-decision method is critical and necessary to help Western physicians rationally use traditional Chinese patent medicines.In this paper,Manifold Ranking is employed to develop the aid-decision model of traditional Chinese patent medicines for stroke treatment.First,115 stroke patients from three hospitals are recruited in the cross-sectional survey.Simultaneously,traditional Chinese physicians determine the traditional Chinese patent medicines appropriate for each patient.Second,particular indicators are explored to characterize the population feature of traditional Chinese patent medicines for stroke treatment.Moreover,these particular indicators can be easily obtained by Western physicians and are feasible for widespread clinical application in the future.Third,the aid-decision model of traditional Chinese patent medicines for stroke treatment is constructed based on Manifold Ranking.Experimental results reveal that traditional Chinese patent medicines can be differentiated.Moreover,the proposed model can obtain high accuracy of aid decision.

BACKGROUND:Heterotopic ossification is a dynamic growth process.Diverse heterotopic ossification subtypes have diverse etiologies or induction factors,but they exhibit a similar clinical process in the intermediate and later phases of the disease.Acquired heterotopic ossification produced by trauma and other circumstances has a high incidence. OBJECTIVE:To summarize the molecular biological mechanisms linked to the occurrence and progression of acquired heterotopic ossification in recent years. METHODS:The keywords"molecular biology,heterotopic ossification,mechanisms"were searched in CNKI,Wanfang,PubMed,Embase,Web of Science,and Google Scholar databases for articles published from January 2016 to August 2022.Supplementary searches were conducted based on the obtained articles.After the collected literature was screened,131 articles were finally included and summarized. RESULTS AND CONCLUSION:(1)The occurrence and development of acquired heterotopic ossification is a dynamic process with certain concealment,making diagnosis and treatment of the disease difficult.(2)By reviewing relevant literature,it was found that acquired heterotopic ossification involves signaling pathways such as bone morphogenetic protein,transforming growth factor-β,Hedgehog,Wnt,and mTOR,as well as core factors such as Runx-2,vascular endothelial growth factor,hypoxia-inducing factor,fibroblast growth factor,and Sox9.The core mechanism may be the interaction between different signaling pathways,affecting the body's osteoblast precursor cells,osteoblast microenvironment,and related cytokines,thereby affecting the body's bone metabolism and leading to the occurrence of acquired heterotopic ossification.(3)In the future,it is possible to take the heterotopic ossification-related single-cell osteogenic homeostasis as the research direction,take the osteoblast precursor cells-osteogenic microenvironment-signaling pathways and cytokines as the research elements,explore the characteristics of each element under different temporal and spatial conditions,compare the similarities and differences of the osteogenic homeostasis of different types and individuals,observe the regulatory mechanism of the molecular signaling network of heterotopic ossification from a holistic perspective.It is beneficial to the exploration of new methods for the future clinical prevention and treatment of heterotopic ossification.(4)Meanwhile,the treatment methods represented by traditional Chinese medicine and targeted therapy have become research hotspots in recent years.How to link traditional Chinese medicine with the osteogenic homeostasis in the body and combine it with targeted therapy is also one of the future research directions.(5)At present,the research on acquired heterotopic ossification is still limited to basic experimental research and the clinical prevention and treatment methods still have defects such as uncertain efficacy and obvious side effects.The safety and effectiveness of relevant targeted prevention and treatment drugs in clinical application still need to be verified.Future research should focus on clinical prevention and treatment based on basic experimental research combined with the mechanism of occurrence and development.

OBJECTIVETo investigate the protective effect of monoside against triptolide-induced liver injury and explore its molecular mechanism.

METHODSBALB/C mice treated with gastric lavage with triptolide and monoside, either alone or in combination, were examined for changes of hepatic biochemical parameters using the serological method. The growth inhibition rate of HepG2 cells treated with triptolide or monoside or both was assessed with MTT assay, and the cell morphological changes were observed using laser confocal microscopy; the expressions of the target proteins in the antioxidative stress pathway were detected using flow cytometry and Western blotting.

RESULTSIn BALB/C mice, gastric lavage of triptolide induced obvious hepatic damage. In HepG2 cells, treatment with triptolide significantly inhibited the cell growth, resulting in a cell viability as low as 72.83% at 24 h; triptolide also induced obvious cell apoptosis and cell nucleus deformation, causing an apoptosis rate of 43.1% in the cells at 24 h. Triptolide significantly reduced the expressions of Nrf2 and HO-1 proteins related with the oxidative stress pathway. Combined treatment with morroniside obviously reversed these changes, resulting in significantly decreased hepatic biochemical parameters and the liver index in BALB/C mice and in significantly lowered cell apoptosis rate, improved cell morphology, and increased Nrf2 and HO-1 protein expressions in HepG2 cells.

CONCLUSIONSMonoside protects against triptolide-induced liver injury possibly by relieving oxidative stress.
