MicroRNAs ( miRNAs ) play important roles in the processes of the occurrence and development of cancers , through regulating tumor related gene expression at post-transcription.It has shown that the expression of miR-214 is aberrant in cervi-cal cancer.Also,miR-214 could affect the proliferation, migration, invasion and apoptosis of tumor cells by targeting various genes . This article focuses on the studies of miR-214 function in cervical cancer , and will provide a novel approach for the clinical diagnosis and the treatment of cervical cancer .

Objective:To investigate the efficacy of ticagrelor combined with atorvastatin in the treatment of unstable angina pectoris and its effects on cardiac function, brain natriuretic peptide (BNP) level, lipoprotein-associated phospholipase A2 (Lp-PLA2) activity, and glycosylated hemoglobin (HbAlc) level in patients with unstable angina pectoris.Methods:A total of 200 patients with unstable angina pectoris who received treatment in the Sahzu International Medical Center from January 2017 to January 2019 were included in this study. These patients were randomly assigned to receive either clopidogrel combined with atorvastatin (control group, n = 100) or ticagrelor combined with atorvastatin (observation group, n = 100) for 1 month. The clinical efficacy,BNP level, Lp-PLA2 activity, HbAlc level, clinical symptom, cardiac function, and adverse reactions were compared between control and observation groups. Results:Effective rate was significantly higher in the observation group than in the control group [95% (95/100) vs. 75% (75/100), χ2 = 15.69, P < 0.001]. After treatment, BNP level and Lp-PLA2 activity in the observation group were (101.21 ± 40.13) ng/L and (105.56 ± 12.56) pg/L, respectively, which were significantly lower than those in the control group [(151.57 ± 37.29) ng/L, (137.52 ± 16.88) pg/L, t = 9.19, 15.19, P < 0.001]. After treatment, the duration and frequency of angina pectoris in the observation group were (1.84 ± 0.49) minutes/time and (1.32 ± 0.21) times/week, respectively, which were significantly lower than those in the control group [(5.23 ± 1.72) minutes/time and (3.58 ± 0.71) times/week, t = 18.95, 30.52, both P < 0.001]. After treatment, the left ventricular end-diastolic diameter and left ventricular end-systolic diameter in the observation group were (33.28 ± 1.21) mm and (47.89 ± 5.61) mm respectively, which were significantly lower than those in the control group [(37.56 ± 2.14) mm, (53.25 ± 5.07) mm, t = 17.41, 7.09, both P < 0.001]. Left ventricular ejection fraction was significantly higher in the observation group than in the control group [(48.59 ± 5.81)% vs. (41.16 ± 5.83)%, t = 9.03, P < 0.001]. The incidence of adverse reactions was significantly higher in the observation group than in the control group [1% (1/100) vs. 12% (12/100), χ2 = 9.96, P = 0.002]. Conclusion:Ticagrelor combined with atorvastatin is highly effective for unstable angina pectoris in coronary heart disease because it greatly decreases BNP level and Lp-PLA2 activity. Therefore, the combined therapy deserves clinical promotion.

Objective:To explore the clinical features and risk factors of in-hospital mortality in idiopathic inflammatory myopathies (IIM) patients.Results:We retrospectively analyzed clinical records of polymyositis (PM), classic dermatomyositis (CDM) and clinically amyopathic dermatomyositis (CADM) patients admitted to the First Affiliated Hospital of Zhejiang University from February 2011 to February 2019. The deceased group was defined as the patients who died in hospital or within 2 weeks after hospital discharge, while the survival group was defined as the survival patients. The clinical features were described. Risk factors for deceased patients were identified by logistic regression analysis.Results:The in-hospital mortality rate of IIM patients ( n=424) was 9.4%. The hospitalization time was longer in deceased group ( n=40) [0.9(0.5, 1.0) m vs 0.6(0.4, 1.0) m, Z=-2.159, P<0.05]. Ferritin [1170.8(757.6, 3 759.9) μg/L vs 374.9(182.1, 993.4) μg/L, Z=-4.665], red blood cell distribution width (RDW) [15.2(14.5, 16.3)% vs 14.4(13.5, 15.2)%, Z=-3.066], CRP con-centrations [11.3(4.4, 36.9) mg/L vs 5.1(1.8, 17.2) mg/L, Z=-2.667] and neutrophil-to-lymphocyte ratio (NLR) [10.1(5.5, 18.9) vs 4.2(2.6, 6.5), Z=-5.108] were higher in deceased group ( P<0.05). Proportion of patients with high levels of CEA (45.0% vs 12.5%, χ2=15.745), glutamyl transpeptidase (γ-GT) (55.0% vs 23.8%, χ2=11.578), fucosidase (AFU) (35.0% vs 10.0%, χ2=10.902) and with complications [including pro-gressive in-terstitial lung disease (ILD) (60.0% vs 16.3%, χ2=23.934), pulmonary infection (72.5% vs 20.0%, χ2=31.360), hemophagocytic lymphohistiocytosis (35.0% vs 1.3%, χ2=27.771) and low T3 syndrome (50.0% vs 17.5%, χ2=16.644) were higher in deceased group ( P<0.05). Steroid pulse therapy and intravenous immuno-globulin therapy were more common in deceased group. Higher on-admission disease activity [ OR=1.593, 95% CI(1.255, 2.022), P<0.001], progressive ILD [ OR=5.600, 95% CI(1.510, 20.772), P=0.010] and pulmonary infection [ OR=6.771, 95% CI(2.031, 22.574), P=0.002] were independent risk factors for death in IIM patients. In su-bsection analysis, pulmonary infection and respiratory failure were short-term adverse prognostic factors for IIM patients with progressive ILD, while heliotrope rash, progressive ILD and increased steroid dose therapy were short-term adverse prognostic factors for IIM patients with pulmonary infection. Conclusion:High disease activity at admission, progressive ILD and pulmonary infection are the independent risk factors for death in IIM patients. Therefore, it is necessary to closely monitor above indicators during hospitalization.

OBJECTIVETo assess the association of four single nucleotide polymorphisms (SNPs) (rs12190359C>T, rs562047C>G, rs1008438G>T, and rs1043618G>C) of HSPA1A gene with the development of cervical cancer among ethnic Han Chinese from Yunnan.

METHODSOne hundred and thirty patients with CIN III, 444 patients with cervical cancer, and 548 healthy individuals were recruited, and the genotypes of the above SNPs were determined with a Taqman assay. Haplotypes were constructed, and their association with the development of cervical cancer was analyzed.

RESULTSThe frequencies of G and T alleles of rs1008438G>T were significant different between the CIN III and control groups, as well as between the cancer and control groups (P=0.022 and P=0.030, respectively). There was a significant difference in genotypic frequency of rs1008438G>T between the CIN III and control groups (P=0.047). The allelic and genotypic frequencies of rs12190359C>T, rs562047C>G, and rs1043618G>C did not significantly differ between the CIN III, cervical cancer and control groups (P> 0.05). The frequencies of haplotypes formed by rs562047C>G, rs1008438G>T and rs1043618G>C also did not significantly differ between the CIN III, cancer and control groups (P> 0.05).

CONCLUSIONThe G allele of rs1008438G>T may be a protective factor for cervical cancer among ethnic Han Chinese from Yunnan.
