Mechanism of Zishen Qinggan Prescription in Improving Glucose and Lipid Metabolism in Type 2 Diabetes Based on Transcriptomics / 中国实验方剂学杂志

ObjectiveBased on network pharmacology and transcriptomics， the mechanism of Zishen Qinggan prescription （ZSQGF） in improving glucose and lipid metabolism in type 2 diabetes （T2DM） model rats was explored. MethodBased on network pharmacology analysis of the differential genes between ZSQGF and T2DM， gene ontology（GO）analysis and Kyoto encyclopedia of genes and genomes（KEGG） analysis were conducted， and molecular docking analysis was used to verify the binding between components and targets. A T2DM rat model was established by high-fat feeding and injection of streptozotocin （STZ）. The rats were randomly divided into the control group， model group， metformin （Met， 72 mg·kg-1） group， and ZSQGF high-， medium-， and low-dose groups （ZSQGF-H， ZSQGF-M， and ZSQGF-L， with 4.8， 2.4， and 1.2 g·kg-1 raw drug in the solution）. The living status of rats was monitored and the levels of total cholesterol （TC）， total triglycerides （TG）， high density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， aspartate aminotransferase （AST）， and alanine aminotransferase （ALT） in rat serum were detected. The liver tissues were subjected to Hematoxylin eosin（HE） staining and oil red O staining. The differential genes were analyzed through transcriptomics， GO and KEGG analysis， and the protein-protein interaction（PPI） network was obtained to screen key targets. With network pharmacology and transcriptomics analysis results， the protein pathways were identified. The expression levels of nuclear factor-κB （NF-κB）， matrix metalloproteinase（MMP）-1 and MMP-9 proteins in liver tissues were detected by Western blot. The mRNA expression of B-cell lymphoma-2（Bcl-2） modifying factor（BMF）， nicotinamide adenine dinucleotide phosphate （NADPH） oxidase 4 （NOX4）， and fatty acid synthase（FASN） was detected by real-time polymerase chain reaction（Real-time PCR）. The expression of MMP-1 and MMP-9 in the liver was detected by immunofluorescence staining. ResultTranscriptomics and network pharmacology analysis suggested that ZSQGF may protect the liver through the glucose and lipid metabolism pathway and the inflammation pathway. Experiments showed that after 8 weeks of administration， the body weight， blood sugar， serum indicators， and pathological staining results of rats were improved. Western blot results indicated a decrease in the relative expression levels of NF-κB， MMP-1 and MMP-9 proteins in the liver. Real-time PCR results showed a decrease in the transcriptional expression of BMF， NOX4， and FASN in the ZSQGF-H group， while immunofluorescence staining results present decreased expression of MMP-1 and MMP-9 in the ZSQGF groups. ConclusionZSQGF can improve the glucose and lipid metabolism by inhibiting the expression of FASN， reducing lipid synthesis， and regulating the NF-κB signaling pathway.

Research Progress of GABA Receptors in Alzheimer’s Disease / 中国生物化学与分子生物学报

Alzheimer’s disease (AD) is a progressive neurodegenerative disease with the early symptom of A β plaque, tau hyperphosphorylation neuronal tangle formation in cells. At present, accumulated evidence shows that the changes of GABA receptors are closely related to AD. Some studies have shown that the expression level of each subunit of the GABA receptor changes in AD patients. Therefore, it is speculated that the changes of GABA subunits may be related to the pathogenesis of AD, but there is no better methods to improve AD by targeting GABA receptors. In order to further understand the relationship between the changes of GABA receptors and AD, this paper first reviewed the changes of GABA receptors in AD patients and animal models’ brains and found that there was differential expression in GABA(A) receptor subunits in AD patients. Then we summarized the changes of GABA receptor subunits in Alzheimer database. Based on the data, we found that a few GABA subunits had significant changes. The evidence shows that the change of GABA receptors alters the neural activity in the brain. Other studies have found that the treatment of mice with GABA receptor agonists and antagonists can improve the cognitive ability of mice. We hope that understanding the differential expression of GABA receptors in AD will provide a more accurate target for the treatment of AD.

Discovery of the mechanisms of acupuncture in the treatment of migraine based on functional magnetic resonance imaging and omics / 医学前沿

Migraine is one of the most prevalent and disabling neurological disease, but the current pharmacotherapies show limited efficacy and often accompanied by adverse effects. Acupuncture is a promising complementary therapy, but further clinical evidence is needed. The influence of acupuncture on migraine is not an immediate effect, and its mechanism remains unclear. This study aims to provide further clinical evidence for the anti-migraine effects of acupuncture and explore the mechanism involved. A randomized controlled trial was performed among 10 normal controls and 38 migraineurs. The migraineurs were divided into blank control, sham acupuncture, and acupuncture groups. Patients were subjected to two courses of treatment, and each treatment lasted for 5 days, with an interval of 1 day between the two courses. The effectiveness of treatment was evaluated using pain questionnaire. The functional magnetic resonance imaging (fMRI) data were analyzed for investigating brain changes induced by treatments. Blood plasma was collected for metabolomics and proteomics studies. Correlation and mediation analyses were performed to investigate the interaction between clinical, fMRI and omics changes. Results showed that acupuncture effectively relieved migraine symptoms in a way different from sham acupuncture in terms of curative effect, affected brain regions, and signaling pathways. The anti-migraine mechanism involves a complex network related to the regulation of the response to hypoxic stress, reversal of brain energy imbalance, and regulation of inflammation. The brain regions of migraineurs affected by acupuncture include the lingual gyrus, default mode network, and cerebellum. The effect of acupuncture on patients' metabolites/proteins may precede that of the brain.

Relationship between nutrient-related dietary pattern and mild cognitive impairment in middle-aged and elderly people in 15 provinces of China / 中华流行病学杂志

Objective: To explore the relationship between nutrient-related dietary pattern and mild cognitive impairment (MCI) in middle-aged and elderly people. Methods: A total of 6 444 middle-aged and elderly people aged ≥55 years were selected in 2018 China Health and Nutrition Survey. MCI was evaluated by Mini-Mental State Examination, and the intakes of various foods were obtained by consecutive 3-day 24-hour dietary survey and weighing method. The intakes of various nutrients and total dietary energy were calculated based on the food composition table. Demographic and social information, lifestyle and health status of the respondents were obtained through questionnaire survey and physical measurements. In this study, vitamin C, vitamin E, zinc, iron, copper and selenium were selected as dependent variables. Nutrient-related dietary patterns were extracted by reduced rank regression method, and the relationship between dietary patterns and MCI was analyzed by multivariate logistic regression model. Results: Six dietary patterns were extracted in this study, and dietary pattern 1 with the highest explanatory degree was selected for subsequent analysis. Dietary pattern 1 was characterized by higher intakes of legume products, vegetables, fruits, nuts, pork, aquatic products and plant oil. Multivariate logistic regression analysis showed that the risk of MCI was lower in Q4 dietary score group than in Q1 dietary score group (OR=0.69, 95%CI: 0.49-0.98) in the 55-64 age group. In people with sleep duration of 8 hours per day, the risk of MCI was reduced in Q2, Q3 and Q4 dietary score groups compared with the Q1 dietary score group, with OR values of 0.68 (95%CI: 0.51-0.92), 0.67 (95%CI: 0.49-0.92) and 0.65 (95%CI: 0.45-0.92), respectively. Interaction analysis showed that the risk for MCI increased in those aged 65-74 years and ≥75 years compared with those aged 55-64 years in Q1 dietary score group. However, the risk for MCI decreased in both age groups as dietary pattern scores increased. Compared with those with sleep duration less or more than 8 hours per day in Q1 dietary score group, those with sleep duration of 8 hours per day in Q2 and Q3 dietary score groups had a reduced risk for MCI. Conclusion: Dietary patterns with higher intakes of legume products, vegetables, fruits, nuts, pork, aquatic products, and plant oil are negatively associated with MCI in people aged 55-64 years and those who slept 8 hours per day, and may reduce the risk of MCI with aging.

Enzyme production mechanism of anaerobic fungus Orpinomyces sp. YF3 in yak rumen induced by different carbon source / 生物工程学报

In order to investigate the enzyme production mechanism of yak rumen-derived anaerobic fungus Orpinomyces sp. YF3 under the induction of different carbon sources, anaerobic culture tubes were used for in vitro fermentation. 8 g/L of glucose (Glu), filter paper (Flp) and avicel (Avi) were respectively added to 10 mL of basic culture medium as the sole carbon source. The activity of fiber-degrading enzyme and the concentration of volatile fatty acid in the fermentation liquid were detected, and the enzyme producing mechanism of Orpinomyces sp. YF3 was explored by transcriptomics. It was found that, in glucose-induced fermentation solution, the activities of carboxymethyl cellulase, microcrystalline cellulase, filter paper enzyme, xylanase and the proportion of acetate were significantly increased (P < 0.05), the proportion of propionate, butyrate, isobutyrate were significantly decreased (P < 0.05). The results of transcriptome analysis showed that there were 5 949 differentially expressed genes (DEGs) between the Glu group and the Flp group, 10 970 DEGs between the Glu group and the Avi group, and 6 057 DEGs between the Flp group and the Avi group. It was found that the DEGs associated with fiber degrading enzymes were significantly up-regulated in the Glu group. Gene ontology (GO) function enrichment analysis identified that DEGs were mainly associated with the xylan catabolic process, hemicellulose metabolic process, β-glucan metabolic process, cellulase activity, endo-1,4-β-xylanase activity, cell wall polysaccharide metabolic process, carbohydrate catabolic process, glucan catabolic process and carbohydrate metabolic process. Moreover, the differentially expressed pathways associated with fiber degrading enzymes enriched by Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were mainly starch and sucrose metabolic pathways and other glycan degradation pathways. In conclusion, Orpinomyces sp. YF3 with glucose as carbon source substrate significantly increased the activity of cellulose degrading enzyme and the proportion of acetate, decreased the proportion of propionate, butyrate and isobutyrate. Furthermore, the degradation ability and energy utilization efficiency of fungus in the presence of glucose were improved by means of regulating the expression of cellulose degrading enzyme gene and participating in starch and sucrose metabolism pathway, and other glycan degradation pathways, which provides a theoretical basis for the application of Orpinomyces sp. YF3 in practical production and facilitates the application of Orpinomyces sp. YF3 in the future.

The results of the nested case-control study showed that the trial group and the control group belonged to the same background baseline， and the occurrence of adverse drug events was more closely related to Ilaprazole sodium for injection. CONCLUSIONS The overall safety of Ilaprazole sodium for injection is relatively high， and the occurrence of adverse events is more related to it.

Pathogenesis and surgical outcomes of different types of myopic traction maculopathy / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To explore the pathogenesis and surgical outcomes of different types of myopic traction maculopathy(MTM)using optical coherence tomography(OCT).METHODS: A total of 193 patients(210 eyes)with MTM were retrospectively included, of which 74 eyes(35.2%)underwent vitrectomy combined with internal limiting membrane(ILM)peeling. The patients were categorized into three groups: foveal detachment(FD), foveoschisis(FS)and lamellar macular hole(LMH). Based on the central foveal thickness(CFT)at baseline(M0), eyes with FD were classified into two subgroups: extensive FD and limited FD. Outcomes included best-corrected visual acuity(BCVA), CFT, posterior staphyloma height(PSH), the presence of epiretinal membrane(ERM)and ILM detachment. Risk factors for BCVA at 6mo after vitrectomy(M6)were analyzed using linear regression.RESULTS: At M0, ERM was highly present in eyes with LMH(rs=0.28, P&#x003C;0.001). Eyes with FD and FS were characterized by higher incidence of ILM detachment(rs=-0.25, P&#x003C;0.001). After vitrectomy, CFT and BCVA significantly improved in all eyes(P&#x003C;0.001). Eyes with extensive FD were characterized by a thicker CFT(rs=0.56, P&#x003C;0.001), a lower incidence of ILM detachment(rs=-0.25, P=0.034)and a thicker nasal PSH(rs=0.27, P=0.024)than eyes with limited FD. Eyes with extensive FD were associated with a worse BCVA at M0(P=0.013)and M6(P=0.030)than eyes with limited FD. Extensive FD(β=-0.295, P=0.042)and BCVA at M0(β=0.669, P&#x003C;0.001)were risk factors for a worse BCVA at M6.CONCLUSION: There are several pathogenetic mechanisms in MTM. ILM detachment may exert a dominant role in the development of FD and FS, while ERM may have a role in LMH. Vitrectomy combined with ILM peeling improved functional and anatomical outcomes in MTM patients. Eyes with extensive FD may carry a poor prognosis.

Compared with the EA group, in the agonist group and the agonist+EA group, ST segment displacement and LF/HF ratio were increased (P<0.01), HRV frequency domain analysis showed enhanced sympathetic nerve excitability, the serum levels of NE, CK-MB and cTnI were increased (P<0.01), the percentage of myocardial infarction area was increased (P<0.01), myocardial fiber breakage and interstitial edema were aggravated, the positive expression and mRNA expression of GABAA receptor in fastigial nucleus were increased (P<0.01).@*CONCLUSION@#EA pretreatment can improve the myocardial injury in MIRI rats, and its mechanism may be related to the inhibition of GABAA receptor expression in fastigial nucleus, thereby down-regulating the excitability of sympathetic nerve.
