Multi-omics analysis of regulating effects of hyperoside on lipid metabolism in high-fat diet mice / 生理学报

The aim of this study was to explore the regulating effects of hyperoside (Hyp) on lipid metabolism in high-fat diet mice. The high-fat diet mouse model was established by high-fat diet induction. After 5 weeks of Hyp intragastric administration in high-fat diet mice, the serum lipid levels before and after Hyp administration were measured by the corresponding kits. The tissue structure of mouse liver was observed by HE staining before and after Hyp administration. The changes of intestinal flora and transcriptome were measured by Illumina platforms. Liquid chromatography-mass spectrometry (LC-MS) was used to determine non-targeted metabolites. The results showed that Hyp significantly reduced lipid levels in the high-fat diet mice and effectively restored the external morphology and internal structure of liver tissue. Hyp changed the species composition of the intestinal flora in high-fat diet mice, increased the abundance of beneficial flora such as Ruminococcus, and decreased the abundance of harmful flora such as Sutterella. Combined multi-omics analysis revealed that the effect of retinoic acid on lipid metabolism was significant in the high-fat diet mice treated with Hyp, while the increase of retinoic acid content was significantly negatively correlated with the expression of genes such as cyp1a2 and ugt1a6b, positively correlated with AF12 abundance, and significantly negatively correlated with unidentified_Desulfovibrionaceae abundance. These results suggest that Hyp may modulate the abundance of AF12, unidentified_Desulfovibrionaceae and inhibit the expression of genes such as cyp1a2 and ugt1a6b, thus increasing the content of retinoic acid and regulating lipid metabolism in the high-fat diet mice.

Clinical Observation of Ordinary Acupuncture plus Zhigou (TE6) and Zhaohai (KI6) for Constipation Due to Yin Deficiency in Parkinson's Disease / 上海针灸杂志

Objective To observe the clinical efficacy of ordinary acupuncture plus Zhigou (TE6) and Zhaohai (KI6) in treating constipation due to yin deficiency in Parkinson's disease. Method Sixty eligible patients were randomized into a control group and a treatment group, 30 cases each. The control group was intervened by ordinary acupuncture by selecting the Dance-tremor Control Zone, Baihui (GV20), Fengchi (GB20), Fengfu (GV16), Quchi (LI11), Yanglingquan (GB34), Taixi (KI3) and Taichong (LR3). Based on the ordinary acupuncture, Zhigou (TE6) and Zhaohai (KI6) were added in the treatment group. The treatment was given three times a week, 12 sessions as a course, and the therapeutic efficacy was evaluated after 2 successive treatment courses by using Patient Assessment of Constipation Quality of Life Scale (PAC-QOL), Bristol Stool Scale (BSS), Cleveland Clinic Score (CCS) and Unified Parkinson's Disease Rating Scale (UPDRS) as the observation indexes. Result Before the intervention, there were no significant differences in comparing the PAC-QOL, Bristol, CCS and UPDRS scores between the two groups (P>0.05);after the treatment, the scores of PAC-QOL, Bristol, CCS, and motor function and activities of daily living in UPDRS dropped significantly in the two groups (P<0.05); the PAC-QOL, Bristol and CCS scores in the treatment group were significantly lower than those in the control group after the treatment (P<0.05); the treatment group had a significantly higher effective rate in improving constipation symptoms than the control group (P<0.05); there was no significant difference in comparing the UPDRS score between the two groups after the intervention (P>0.05). Conclusion Ordinary acupuncture plus Zhigou and Zhaohai can significantly improve the quality of life, stool form and difficulty in defecation in constipation of yin-deficiency type in Parkinson's disease, and the therapeutic efficacy is superior to that of ordinary acupuncture.

Study on clinicopathologic grading system and prognosis of primary hepatic neuroendocrine neoplasms / 中华病理学杂志

<p><b>OBJECTIVE</b>To study the clinicopathologic features, criteria for grading and prognostic factors of primary hepatic neuroendocrine neoplasms.</p><p><b>METHODS</b>Thirty-five cases of primary hepatic neuroendocrine neoplasm were retrieved from the archival files over a period of 11 years (with 32 cases having integrated data). According to the 2010 WHO classification of tumors of the digestive system, the cases were categorized into three groups: neuroendocrine tumor grade 1 (NET G1), neuroendocrine tumor grade 2 (NET G2) and neuroendocrine carcinoma (NEC). Statistical correlation between various histologic parameters and survival data was analyzed.</p><p><b>RESULTS</b>Statistical analysis showed significant difference between NET [G1 (1 case)/G2 (14 cases)] and NEC (17 cases) groups in terms of tumor differentiation, necrosis, nuclear atypia, mitotic count and Ki-67 proliferative index (P < 0.05). There was no statistically significant difference in tumor size, growth pattern and presence of vascular tumor emboli (P > 0.05). The survival rate of patients correlated with tumor differentiation, growth pattern, necrosis, nuclear atypia, mitotic count and proliferative index (P < 0.05). There was no statistically significant difference between patient survival and tumor size or presence of vascular tumor emboli (P > 0.05).</p><p><b>CONCLUSIONS</b>The subdivision of primary hepatic neuroendocrine neoplasm according to the 2010 WHO classification of tumors of the digestive system helps to evaluate the malignant potential and prognosis of the tumors. Prognostically useful histologic parameters include tumor differentiation, growth pattern, necrosis, nuclear atypia, mitotic count and proliferative index.</p>
