Objective:To investigate the effect of metformin on the microRNA (miRNA) expression and screen potential target with network pharmacology analysis in patients with type 2 diabetes.Methods:Fifteen patients with new diagnosed type 2 diabetes admitted to our hospital were selected, who received metformin during hospitalization and after discharge. The expression of serum matrix metalloproteinase (MMP)-9, transforming growth factor (TGF)-β1, and myocardial fibrosis related miRNAs were compared before and 6 month after metformin treatment. In addition, gene ontology (GO) and KEGG pathway enrichment analysis were applied to analyze differential expression miRNAs showing statistical significance. Meanwhile, the network figure was established to reflect the target gene messenger RNA (mRNA) corresponding to differentially expressed miRNA.Results:Compared with pre-medication, the serum level of MMP-9 was significantly decreased after treatment ( P<0.05). Besides, the expression of homo sapiens microRNA (hsa-miR)29a-3p, hsa-miR133a-5p, hsa-miR21-5p, hsa-miR30c-5p, and hsa-miR1-3p in patients with type 2 diabetes were dramatically down-regulated by metformin ( P<0.05 or P<0.01). Results of GO analysis and KEGG pathway enrichment analysis showed that differentially expressed miRNAs were mainly concentrated in endoplasmic reticulum lumen, synapse, basement membrane and other cell components. The molecular functions such as Rho GTPase binding and participation in extracellular matrix structural constituent were exerted through biological processes such as collagen catabolic process, regulation of short-term neuronal synaptic plasticity, and axon extension, which were mainly enriched in advanced glycation end products-receptor for advanced glycation end products (AGE-RAGE) signaling pathway in diabetic complications, tumor necrosis factor (TNF) signaling pathway, and Wnt signaling pathway, etc. The outcome of miRNA-mRNA network analysis demonstrated that there were 230 target genes mRNAs corresponding to differentially expressed miRNA. Conclusion:Metformin could play its role in the treatment of type 2 diabetes by down regulating the expression of miRNA, participating in the transduction of related cellular signaling pathways, regulating chromatin, nucleic acid binding, and enzyme activities.

Objective:To explore the efficacy and safety of sivelestat, a neutrophil elastase (NE) inhibitor, in the treatment of acute lung injury (ALI) in the intensive care unit (ICU).Methods:A retrospective analysis was performed on 171 patients with ALI in the ICU of the First Affiliated Hospital of Zhengzhou University from June 2020 to June 2021, including 77 patients in the sivelestat group and 94 patients in the conventional treatment group. Acute physiology and chronic health evaluation (APACHE) Ⅱ score, Murray lung injury score, oxygenation index (PaO 2/FiO 2 ratio), inflammatory cytokines (IL-6, IL-10, TNF-α), ventilator-free days (VFD), the length of ICU stay, and the 28-day mortality were collected to assess the efficacy of sivelestat. At the same time, adverse reactions and laboratory test results within 30 days after the use of sivelestat were recorded to assess the safety. Results:Compared with conventional treatment, oxygenation index, Murray lung injury scores, IL-6, IL-10, and TNF-α were significantly improved after 7 days of sivelestat treatment. Compared with the conventional treatment group, the VFD was significantly longer ( P = 0.0119) and the length of ICU stay was significantly shorter ( P = 0.0269) in the sivelestat group. The mortality was 14.29% in the sivelestat group and 22.34% in the conventional treatment group and, with no statistically significant. In the meantime, sivelestat did not increase adverse reactions within 30 days after treatment. Conclusions:Sivelestat treatment is safe and more effective than conventional treatment for ALI patients in the ICU.

Objective:To explore the correlation between sleep duration and incident diabetes among residents of different ages in Xinjiang region.Methods:A total of 9 541 residents, aged 40 and over in Karamay, Xinjiang were identified by a cluster sampling method. Physical examinations and biochemical test were performed, and the data on sleep duration and lifestyle were obtained using standardized questionnaires. The population was divided into three categories according to sleep duration: insufficient sleep(<6 h), ideal sleep(6-8 h), and long sleep duration(>8 h). They were further divided into 2 subgroups based on age at survey. Those who were younger than 60 years old were defined as the middle-aged group, and the rest as the elderly. Multivariate logistic regression analysis was used to explore the correlation between sleep duration and the risk of diabetes in different age groups.Results:There existed an approximate U-shaped relationship between total sleep duration and fasting blood glucose as well as HbA 1C. Fasting blood glucose and HbA 1C were relatively lower among those with ideal sleep duration. After multivariable adjustment, residents with insufficient sleep revealed a 35% increased risk of diabetes( OR=1.35, 95% CI 1.06-1.71) compared with those with ideal sleep duration. However, the risk of diabetes was not significantly increased in those with long sleep duration( OR=1.04, 95% CI 0.94-1.14). Furthermore, the additive risk of insufficient sleep was only significant in the middle-aged group( OR=1.37, 95% CI 1.02-1.84). Conclusions:Among residents of different ages in Xinjiang region, insufficient sleep is associated with an increased risk of diabetes, which is only significant in the middle-aged group.

Objective:To investigate the effect and mechanism of isorhynchophylline (IRN) on angiotensin Ⅱ(Ang Ⅱ)-induced cardiac hypertrophy.Methods:H9c2 cells were co-cultured with Ang Ⅱ and different concentrations of IRN (0, 5, 10, 25, 50 μmol/L). The cell surface area and mRNA levels of cardiac hypertrophy markers atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP) and β-myosin heavy chain (β-MHC) were detected to elucidate the effect of IRN on myocardial hypertrophy and the most effective concentration. H9c2 cells were co-cultured with Ang Ⅱ and IRN (25 μmol/L) at different times (0, 6, 12, 24 h) to elucidate the most effective time of inhibition. The phosphorylation levels of the signaling pathway were detected, and the effects of IRN and Akt inhibitor MK2206 on the phosphorylation levels of the signaling pathway were further explored to elucidate the underlying mechanisms.Results:Compared with the control group, the surface area of H9c2 cells, and the mRNA expression of myocardial hypertrophy markers ANP, BNP and β-MHC were significantly increased (all P<0.05). Pretreated with different concentrations of IRN (5, 10, 25, 50 μmol/L) could inhibit the increase in cell surface area induced by AngⅡ (all P<0.05), especially at the concentration of 25 μmol/ L ( P<0.01). IRN could time-dependently inhibit AngⅡ-induced activation of ANP, BNP, β-MHC mRNA (all P<0.05). AngⅡ caused increased phosphorylation levels of Akt, GSK3β, mTOR and FOXO3a. IRN could block AngⅡ-induced phosphorylation of the Akt signaling pathway. Conclusion:IRN attenuates AngⅡ-induced cardiomyocyte hypertrophy by inhibiting the Akt signaling pathway.

Objective:To assess the efficacy and safety of programmed death-1 (PD-1) inhibitor combined with radiotherapy in advanced and relapsed / refractory extranodal NK/T cell lymphoma (ENKTL).Methods:Clinical data of 26 patients with advanced and recurrent / refractory ENKTL admitted to Sun Yat-sen University Cancer Center from January 2019 to December 2021 were retrospectively analyzed. All patients were treated with the PD-1 inhibitor combined with radiotherapy. The treatment responses, survival rate and and adverse reactions of the regimen were analyzed. The Kaplan-Meier method was used to estimate the 1- and 2-year progression-free survival (PFS) rate and overall survival (OS) rate, and the Cox proportional risk model was used for univariate prognostic factorial analysis for PFS and OS.Results:The median follow-up time of 26 patients was 29 months (10-49 months). The objective response rate (ORR) was 85%. The complete and partial remission rates were 77% and 8%. The median PFS time was 25 months. The 1- and 2- year PFS rates were 73.1% and 53.3%. The 1- and 2- year OS rates were 88.5% and 75.3%. The main adverse reaction was acute mucositis with an incidence rate of 31% (8/26), followed by hematological toxicity. The incidence of immune-related adverse events in lung, liver and thyroid were low. Only 1 patient developed grade 3 acute mucositis, 1 patient developed grade 4 immune pneumonitis, and the remaining patients had grade 1-2 toxicities. All patients showed good tolerance. The univariate analysis showed that elevated lactate dehydrogenase, Epstein-Barr virus DNA positive after treatment, and less than 6 cycles of anti-PD-1 immunotherapy were prognostic factors for poor OS.Conclusion:The regimen of PD-1 inhibitor combined with radiotherapy demonstrates promising efficacy and well tolerance in patients with advanced and relapsed / refractory ENKTL.

ObjectiveTo evaluate the methodological and reporting quality of clinical practice guidelines for Chinese patent medicine (CPM) with internationally recognized tools the appraisal of guidelines for research and evaluation (AGEREE) Ⅱ and reporting items for practice guidelines in healthcare (RIGHT), thereby providing refe-rence for the clinical application and future development of CPM guidelines. MethodsDatabases including CNKI, VIP, Wanfang and Sinomed were searched for CPM guidelines, as well as medlive.cn, websites of China Association of Chinese Medicine and Chinese Medical Association, and reference lists of the included papers. The quality of the guidelines was evaluated using the AGREE Ⅱand RIGHT tools, and consistency tests were performed using Interclass Correlation Coefficient, and descriptive analysis and chi-square test were used to analyze the reporting rate for each domain and the average score for each item. ResultsFinally, 140 CPM guidelines were included, of which 51 were disease-oriented and 89 were drug-oriented, all of which were issued by China. For 51 disease-oriented CPM guidelines, the highest average score of all six AGREE Ⅱ domains was 73.32% for clarity, and the lowest was 26.80% for application; for 89 drug-oriented CPM guidelines, the highest average score was 55.62% for scope and purpose, and the lowest was 31.32% for rigour of development. In terms of the seven domains of the RIGHT checklist, the highest reporting rate was 68.26% for background, and lowest was 27.45% for other areas regarding the disease-oriented CPM guidelines; the highest reporting rate was 61.31% for background, and the lowest was 4.49% for other areas regarding drug-oriented CPM guidelines. The average reporting rate was higher for disease-oriented than drug-oriented CPM guidelines in three domains of AGREE Ⅱ (rigour of development, clarity of presentation, editorial independence), as well as four domains of RIGHT checklist (basic information, evidence, funding and declaration and management of interests, and other areas). ConclusionThe overall methodology and reporting quality of the current CPM guidelines still need to be improved. It is recommended that future guideline development teams should strictly refer to the AGREE Ⅱ and RIGHT checklist, and take into account of the characteristics of CPM guidelines and relevant methodo-logical suggestions in the development and reporting of CPM guidelines, thereby guiding the clinical use of CPM in a better way.

Genome editing tools such as the clustered regularly interspaced short palindromic repeat (CRISPR)-associated system (Cas) have been widely used to modify genes in model systems including animal zygotes and human cells, and hold tremendous promise for both basic research and clinical applications. To date, a serious knowledge gap remains in our understanding of DNA repair mechanisms in human early embryos, and in the efficiency and potential off-target effects of using technologies such as CRISPR/Cas9 in human pre-implantation embryos. In this report, we used tripronuclear (3PN) zygotes to further investigate CRISPR/Cas9-mediated gene editing in human cells. We found that CRISPR/Cas9 could effectively cleave the endogenous β-globin gene (HBB). However, the efficiency of homologous recombination directed repair (HDR) of HBB was low and the edited embryos were mosaic. Off-target cleavage was also apparent in these 3PN zygotes as revealed by the T7E1 assay and whole-exome sequencing. Furthermore, the endogenous delta-globin gene (HBD), which is homologous to HBB, competed with exogenous donor oligos to act as the repair template, leading to untoward mutations. Our data also indicated that repair of the HBB locus in these embryos occurred preferentially through the non-crossover HDR pathway. Taken together, our work highlights the pressing need to further improve the fidelity and specificity of the CRISPR/Cas9 platform, a prerequisite for any clinical applications of CRSIPR/Cas9-mediated editing.
