Abstract:
ObjectiveTo study the effects of leng noncoding RAN small nucleolar RNA host gene 15(LncRNA SNHG15) and microRNA-451a(miRNA-451a) on the biological activity of breast cancer cells.MethodsThe expression levels of SNHG15, miRNA-451a and chemokine receptor 4(CXCR4) in drug-resistant breast cancer SKBR3-PR cells were detected using qRT-PCR.The effects of the SNHG15 and miRNA-451a inhibitors on SKBR3-PR cells migration were determined by cell scratch assay.Flow cytometry was used to detect the apoptosis, and the protein expression levels of CXCR4, epithelial mesenchymal transformation(EMT)-related proteins Vimentin and Snail were detected by Western blotting.ResultsCompared with the parent cells, the expression level of miRNA-451a decreased(P<0.05), the expression level of CXCR4 was up-regulated in drug-resistant breast cancer cell lines(P<0.01).The results of cell scratch assay showed that the SNHG15 promoted cell migration(P<0.01), and the miRNA-451a inhibited cell migration(P<0.01).The results of apoptosis assay showed that the SNHG15 inhibited apoptosis(P<0.01) and the miRNA-451a promoted apoptosis(P<0.01).After interfering SNHG15, the results of Western blotting showed that the expression levels of EMT-related proteins Snail and CXCR4 decreased, the expression levels of Snail and CXCR4 increased in miRNA-451a inhibitor group(P<0.01), and the differences of the Vimentin expression level was not statistically significant(P>0.05).ConclusionsLncRNA SNHG15 may promote the migration and apoptosis of breast cancer cells by regulating miRNA-451a, and potentially regulate CXCR4 to induce EMT of breast cancer cells.

Abstract:
ObjectiveTo investigate the inhibitory effect and mechanism of novel recombinant myricetin on 4T1 cells.MethodsA new myricetin derivative was synthesized by modifying the chemical formula of myricetin.CCK-8 cell proliferation inhibition assay, and half inhibitory concentration(IC50) was calculated.The effects of novel myricetin on the migration and invasion of 4T1 cells were observed by scratch and Transwell assay.Flow cytometry was used to observe the changes of the cycle and apoptosis of 4T1 cells after the intervention of synthetic myricetin.The inhibitory effect of the novel myricetin on triple negative breast cancer(TNBC) was evaluated in the mouse tumor transplantation model in vivo.HE and TUNEL staining were used to observe the cell necrosis and apoptosis in transplanted tumor tissue sections of mice.Finally, the expression of related proteins(P53, Bcl2, Bax, Caspase 3) in 4T1 cells after intervention was detected by Western bloting.ResultsThe IC50 was 5.5 μmol/mL.Compared with DMSO group, the cell count and migration rate of 4T1 cells were decreased after treated with 5.5 μmol/mL novel myricetin for 24 h(P<0.01).Flow cytometry and TUNEL staining of tumor tissue sections showed that compared with DMSO group, the number of apoptotic cells was increased, the proportion of G1 phase cells was lower, the proportion of G2 phase cells was higher, the tumor growth volume and tumor weight were smaller, p53 and Bcl2 proteins were down-regulated, Caspase 3 was up-regulated in 5.5 μmol/mL recombinant myricetin group(P<0.05 to P<0.01).ConclusionsThe novel recombinant myricetin can induce the apoptosis and inhibit proliferation of 4T1 cells in vitro and in vivo, which may inhibit the proliferation of 4T1 cells by down-regulating p53 and induce the apoptosis of 4T1 cells through the Bcl2 mitochondrial apoptosis pathway.

Abstract:
ObjectiveTo observe the inflammatory cytokines expression of lung tissue and the changes of miR126a-5p and miR155-5p in septic mice after vitamin C(Vit C) intervention, and to analyze the potential protective mechanism of Vit C in the acute lung injury in sepsis.MethodsA total of 18 male mice(4 to 6 weeks) were selected and randomly divided into the control group(CON), sepsis+NS group(SEP) and sepsis+Vit C intervention group(SEP+IR), before the injection of Vit C 1 000 mg/kg by tail vein for three consecutive days in the cecum puncture ligation model.Wet weight/dry weight(W/D) of lung tissue was measured 12 h after operation.HE staining was used to observe the pathological appearance of lung and the diameter of alveoli was measured.The changes of miR126a-5p and miR155-5p were detected by RT-qPCR, the protein expressions of Caspase 1 and Caspase 3 were detected by Western blot, and the expressions of IL-6 and TNF-α were detected by ELISA.ResultsCompared with CON group, the W/D of lung in SEP group was increased and the alveolar aperture was decreased significantly in SEP group.The expressions of miR126a-5p, miR155-5p, Caspase 1 and Caspase 3 were increased in SEP group.Meanwhile, the inflammatory cytokines IL-6 and TNF-α were further increased(P<0.05).Compared with SEP group, SEP+IR group had lower W/D, higher alveolar pore size, lower expression in miR126a-5p, miR155-5p, Caspase 1 and Caspase 3.Vit C further inhibited the increase of inflammatory cytokines IL-6 and TNF-α(P<0.05).ConclusionsVit C can reduce pulmonary edema and stabilize alveolar volume, which may be related to the decreased expressions of Caspase 1 and Caspase 3 induced by miR126a-5p and miR155-5p.

Abstract:
ObjectiveTo explore the correlation between the level of high density lipoprotein(HDL-C) in peripheral blood and inflammatory index, renal function and insulin resistance in diabetic nephropathy.MethodsAccording to the 24-hour urinary microalbuminuria excretion rate(UAER), 246 patients with type 2 diabetes mellitus were divided into the normal albuminuria group(98 cases with UAER < 30 mg/24 h), microalbuminuria group(60 cases with UAER < 300 mg/24 h) and massive albuminuria group(88 cases with UAER≥300 mg/24 h), and 92 healthy subjects were set as the control group.The differences of the expression levels of inflammatory factors, renal function index and insulin resistance index were compared among four groups, and the correlation between HDL-C and each index was analyzed.ResultsThere was no statistical significance in the levels of cholesterol among four groups(P>0.05).The levels of the fasting blood glucose(FBG), triglyceride(TG), glycosylated hemoglobin(HbA1c), interleukin-6(IL-6), tumor necrosis factor α(TNF-α), hypersensitive C-reactive protein(hs-CRP), blood urea nitrogen(BUN), blood creatinine(Scr), fasting insulin(FINS) and insulin resistance index(HOM) in control group were lower than those in other three groups, while the levels of HDL-C, glomerular filtration rate(eGFR), insulin sensitivity index(ISI) and insulin secretion index(HOMA-β) in control group were significantly higher than those in other three groups(P < 0.05 to P < 0.01).In the normoalbuminuria group, microalbuminuria group and macroalbuminuria group, the levels of the FBG, TG, HbA1c, IL-6, TNF-α, hs-CRP, BUN, Scr, FINS, HOMA-IR showed an increasing trend, and the levels of HDL-C, eGFR, ISI and HOMA-β showed a decreasing trend(P < 0.05 to P < 0.01).The levels of HDL-C in diabetic nephropathy patients were negatively correlated with the course of disease, FBG, IL-6, hs-CRP, Scr and FINS, but positively correlated with eGFR and HOMA-β(P < 0.05 to P < 0.01).ConclusionsThe HDL-C is correlated with the inflammatory response, renal function and islet function in diabetic nephropathy patients, which has high clinical guiding significance.

Abstract:
ObjectiveTo investigate the effects of fibroblast growth factor-21(FGF-21) and bone morphogenetic protein-2(BMP-2) on vascular calcification of autologous arteriovenous fistula(AVF) in maintenance hemodialysis patients.MethodsTwenty maintenance hemodialysis patients treated with internal fistula repair and 20 patients treated with primary internal fistula operation at stage 4-5 of chronic kidney disease in the Department of Nephrology of The First Affiliated Hospital of Bengbu Medical College were selected as the observation group, and 20 healthy people matched with age and gender in the health examination center were selected as the control group.The internal fistula blood vessels from establishing autogenous arteriovenous fistula operation(cephalic vein tissue of early fistula patients or arterialized venous cephalic vein of repairing fistula patients) were stained with alizarin red S to detect the presence of calcification, and calculate the calcification score for calcified stage(including severe calcification group, light and moderate calcification group and noncalcification group).The clinical data, serum biochemical parameters, and brachial and ankle pulse wave conduction velocity(baPWV) in all cases were collected.The serum concentrations of FGF-21 and BMP-2 in all cases were determined by ELISA, the immunohistochemistry was used to detect the expression levels of FGF-21 and BMP-2 in the vascular wall of internal fistula in the observation group.ResultsThe serum levels of FGF-21 and BMP-2 in observation group were significantly higher than those in control group(P < 0.01).With the aggravation of vascular calcification, the serum levels of FGF-21 and BMP-2 increased, and the expression levels of FGF-21 and BMP-2 in the immune tissue of the vascular wall with higher calcification degree also increased(P < 0.05).The levels of FGF-21, BMP-2, serum phosphorus, creatinine, parathyroid hormone and baPWV in the observation group were positively correlated with the vascular calcification of internal fistula(rs=0.850, 0.769, 0.718, 0.433, 0.441 and 0.457, respectively)(P < 0.01).ConclusionsThe levels of FGF-21 and BMP-2 are correlated with the vascular calcification of autologous arteriovenous fistula in patients with maintenance hemodialysis, which can be used as the reference for monitoring the vascular calcification of internal fistula.

Abstract:
ObjectiveTo investigate the medication compliance of elderly hypertension patients in the community and put forward feasible suggestions for the health management of hypertension patients.MethodsA total of 120 elderly hypertension patients over 60 years old in Yijishan community from July to September 2020 were selected.Information was collected through questionnaires and interviews.One hundred and nineteen cases were effectively surveyed, but 1case was invalid.The Morisky scale questionnaire was used to evaluate patients' medication compliance, and the influencing factors of medication compliance were analyzed.ResultsAmong the 119 patients, 52 patients(43.7%) had good medication compliance, 67 patients(56.3%) had poor medication compliance, among which 23 cases(34.33%)had poor compliance due to forgetting to take medication, followed by 21 cases(31.34%)who stopped medication without taking medication because of symptom improvement, and 23 cases(34.33%)who stopped medication and did not pay attention to taking medication because of conscious symptom worse.Age, times of medication, residence status and blood pressure monitoring were the main influencing factors for low compliance(P < 0.05).Logistic regression analysis showed that living alone and having no blood pressure monitoring increased the risk of decreased medication compliance by 16.9% and 10.4%.ConclusionsMedical staffs and pharmacists should strengthen the publicity of the relevant knowledge of hypertension patients, carry out systematic health education for patients, improve their compliance, and improve the standardization of hypertension treatment and blood pressure control level.
