Different types of noncoding RNAs (ncRNAs) are pervasively expressed in genomes of complex organisms.Current evidence suggests that long noncoding RNAs (lncRNAs) have significant roles at almost every stage of gene expression.It is an important regulatory factor involving in ischemic heart diseases,participating in the development of ischemic heart disease,expecting to predict early myocardial remodeling after myocardial infartion and heart failure,and attracting more and more attention.This review introduces the definition,classification,function and characteristics of lncRNA,and focuses on its diagnostic and predictive value in ischemic heart disease.

Objective To investigate if the relative ratio between C1q and C3a, C5a had a relationship with the extent of coronary artery disease ( CAD) which had never been evaluated in humans.Methods Fifty-three patients scheduled for elective percutaneous coronary intervention ( PCI ) from February, 2016 to April, 2016 at Fuwai hospital were prospectively enrolled.According to the clinical and angiographic characters patients were divided into two groups:acute coronary syndrome ( ACS) group ( n=24), and control group (n=29, 19 patients with stable angina and 10 patients without CAD confirmed by angiography).In all individuals, fasting venous blood was collected by EDTA tubes after admission and strictly before PCI.The plasma level of C1q was measured by immune turbidimetric analysis, C3a and C5a were measured by ELISA tests.Differences between groups were assessed using t test, Mann-Whitney Utests, chi-squared test or Fisher exact test depending on the type of data respectively.Multivariate logistic regression analyses were conducted to evaluate the adjusted effect of C1q, C3a, C5a, C1q/C3a and C1q/C5a on ACS.Results Compared with control group, ACS group has an elevated circulation level of C3a (4 531.14 μg/L vs.4 179.95 μg/L, t=1.381,P=0.173) and C5a (6.44 μg/L vs.4.42 μg/L, t=0.133, P=0.108) but a decreased level of C1q (176.98 μg/ml vs.200.60 μg/ml, t=-2.022, P=0.048).The relative ratio of C1q/C3a was significantly decreased in ACS patients(4.05 ×10 -2 vs.4.97 × 10 -2 , t=-2.484, P=0.016).According to the multiple logistic regression analysis, lower relative ratio of C1q/C3a level proved to be independently associated with ACS ( OR=0.937, P=0.047, 95% CI:0.879-0.998).Conclusions The decreased relative ratio of C1q/C3a level proved to be independently associated with ACS.C1q/C3a ratio could be used as an important index reflecting the complement system homeostasis status which might have potential clinical value in evaluating the prognosis of patients with CAD.

Aim To investigate the effect of p38 MAPK AS-ODNs on the expression of GLT-1 during the induction of brain ischemic tolerance induced by cerebral ischemic preconditioning (CIP).Methods Eighty healthy male Wistar rats with permanent occlusion of the bilateral vertebral arteries were randomly divided into 6 groups: ①Sham group (n=10);②CIP group (n=10);③ischemic insult (Ⅱ) group (n=10);④CIP+Ⅱ group (n=10);⑤p38 MAPK AS-ODNs+CIP+Ⅱ group (n=30);⑥p38 MAPK S-ODNs+CIP+Ⅱ group (n=10).Group ⑤ was divided into 5 nmol, 10 nmol and 15 nmol subgroups according to the dose of p38 MAPK AS-ODNs (n=10).The dose of p38 MAPK S-ODNs was 15 nmol.All the rats were sacrificed 6 h and 2 d after the sham operation or the last time of global brain ischemia reperfusion.Western blot and immunohistochemistry analysis were used for detecting the expression of p-p38 MAPK and GLT-1 protein.Results CIP moderately up-regulated the expression of p-p38 MAPK and significantly up-regulated the expression of GLT-1 protein, inhibited the excessively up-regulation of p-p38 MAPK and the down-regulation of GLT-1 induced by ischemic insult.p38 MAPK AS-ODNs significantly inhibited the up-regulation of p-p38 MAPK and GLT-1 protein in a dose-dependent manner during the induction of brain ischemic tolerance by CIP.Conclusion p38 MAPK AS-ODNs inhibit the up-regulation of GLT-1 during the induction of brain ischemic tolerance induced by CIP.

Objective: To analyze the thromboelastography (TEG) outcomes in patients with stable angina pectoris (SAP) combining diabetes mellitus (DM).
Methods: A total of 360 SAP patients treated in our hospital by percutaneous coronary intervention (PCI) from 2012-01 to 2013-06 were randomized into 2 groups:SAP+DM group, n=109 and SAP-DM group, n=251. Routine clinical examination and TEG test were performed and compared between 2 groups.
Results: Compared with SAP-DM group, SAP+DM group showed the higher ratios of male gender, history of hypertension, hyperlipidemia and higher level of hs-CRP, all P<0.05. Single regression analysis indicated that DM was related to adenosine diphosphate (ADP) inhibition rate (r=0.977, P=0.0001), not related to arachidonic acid (AA) inhibition rate (r=0.245, P=0.069). Multi regression analysis presented that with controlled relevant factors, DM was still related to ADP inhibition rate (r=0.862, P=0.0001). The major TEG parameters as R value, K value,α-angle and MA value were obviously different between 2 groups, P<0.05, while the AA inhibition rate was similar, P=0.057. ADP inhibition rate was different between 2 groups, P=0.0001. The incidence of clopidogrel resistance was higher in SAP+DM group than that in SAP-DM group (34.7%vs 16.2%, P=0.001).
Conclusion: The SAP patients combining DM were at hyper-coagulation status with higher incidence of clopidogrel resistance, who needed intensive post-operative anti-platelet therapy.

Objective To investigate the effect of low oxygen tension (7.5% O2) on human embryo development in vitro and outcome of women undergoing IVF-ET. Methods The data of 280 routine IVF cycles with fresh embryo transfer on day3 conducted in the 2nd People's Hospital of Yunnan Province from February 2012 to August 2013 were retrospectively analyzed. Two groups, 7.5%O2 low oxygen tension (n=120) and 20%O2 high oxygen tension (n=160),were setup for early embryo (D1-D3) development in vitro. Results Good quality embryo on day 3 in low oxygen tension group showed morphologically appearance of blastomere mutually clinging to each other,a characteristic of slight compaction. Higher rate of good quality embryo (66.22%V. 47.54%) and of clinical pregnancy (53.33%v. 39.22%) were found in the low oxygen tension group. There were no significantly differences in rates of fertilization,cleavage and embryo utilization respectively between the two groups ( all>0. 05) . Conclusion High quality early stage human embryos can be developed in vitro in low oxygen tension, and may improve clinic outcome of IVF.

Objective To investigate the relationships and types between pulmonary subsolid nodules and bronchi and vessels,and their diagnostic values in differentiating subsolid nodules.Methods MSCT images of 40 subsolid nodules were retrospectively reviewed.The relationships between subsolid nodules and bronchi were divided into five types.Type Ⅰ:the bronchi were “cutoff”in the solid part of nodules.Type Ⅱ:the bronchi were distortion and extension in the solid parts of nodules.Type Ⅲ:the bronchi were distortion and extension in the GGO parts of nodules.Type Ⅳ:the bronchi were normal course in the GGO parts of nodules.Type Ⅴ:the bronchi were circumvent nodule lesions.The relationships between subsolid nodules and vessels were categorized into four types.Type Ⅰ:vessels passing by SSNs;Type Ⅱ:intact vessels passing through SSNs;Type Ⅲ:distorted,dilated or tortuous vessels seen within SSNs;Type Ⅳ:more complicated vessels other than described above.The relationship types were correlated to pathologic and/or clinical findings of subsolid nodules.Results Of 40 subsolid nodules,4 were preinvasive nodules,6 micro infiltrating adeocarcinomas and 30 invasive ones that were pathologically proven.Types Ⅰ,Ⅱ,Ⅲ and Ⅳ vascular relationships were observed in 0,8,21 and 11 subsolid nodules,respectively.Type Ⅲ relationship was the dominating one.All 11 subsolid nodules were invasive adenocarcinomas,when the relationship between subsolid nodules and vessle was type Ⅳ.There were 17 invasive adenocarcinomas,2 preinvasive ones,and 2 infiltrating ones when the relationship between subsolid nodules and vessel was type Ⅲ.Correlation analysis showed strong correlation between invasive adenocarcinoma and type Ⅲ and Ⅳ relationships.There was significantly statistical significance among 3 groups of relationships between subsolid nodule and vessels(χ2 =1 5.1 90,P =0.004).Types Ⅰ,Ⅱ,Ⅲ,Ⅳ and V brochi relationships were observed in 20,5,6,9 and 0 subsolid nodules,respectively.Type I relationship was the dominating relationship.There were 1 7 invasive adenocarcinomas, 1 preinvasive one,2 micro invasive ones when the relationship between subsolid nodules and bronchi were typeⅠ.There was significantly statistical significance among 3 groups of relationships between subsolid nodule and bronchi (χ2 =23.81 1,P =0.001 ).Conclusion Different subsolid nodules have different relationships with bronchi and vessels.Understanding and recognizing the characteristic subsolid nodule-bronchi and subsolid nodule-vessel relationships may help to identify which nodules are more likely to be malignant.

Brown adipose tissue (BAT) increases energy consumption by directly dissipating stored energy in the form of heat through the role of uncoupling protein (UCP1). Recent studies have found that brown adipocytes may also regulate metabolism through autocrine, paracrine, and endocrine mechanisms. A growing body of evidences have shown that the BAT has a close relationship with bone metabolism, in which BAT secretes a variety of factors to regulate bone metabolism, while bone also secretes a variety of bioactive substances to control BAT function. In addition, BAT may indirectly participate in bone metabolism through muscle-mediated regulation or SNS activity and improvement of body metabolism, thus forming a BAT-skeletal axis. In this paper, we try to explain the relationship between brown adipose tissue and bone, and to discuss their interactive mechanisms.

Objective To analyze the clinical characteristics and prognosis of patients with rectal gastrointestinal stromal tumor ( GIST) . Methods We collected the data of 31 rectal GIST patients definitely demonstrated by pathology and immunohistochemistry in the First Affiliated Hospital of Soochow University, the Second Affiliated Hospital of Soochow University, and Suzhou Wuzhong People′s Hospital from January 2008 to December 2016. The clinical characteristics, therapeutic modalities, and prognoses were retrospectively analyzed. Results Among the 31 rectal GIST patients, 16 underwent local resection and 15 underwent radical surgery. There was no significant difference on the three-year survival rate between the two groups [ 93. 8％ ( 15/16 ) VS 73. 3％ ( 11/15 ) , P=0. 135 ] . There was no significant difference on the survival rate between the oral imatinib patients and non-oral imatinib patients in the local resection group [ 75. 0％ ( 3/4) VS 100. 0％ ( 12/12) , P=0. 083] and the radical surgery group[ 77. 8％ ( 7/9) VS 66. 7％(4/6), P=0. 579]. The postoperative recurrence and metastasis rate of the two groups was no significantly different[31. 3％ (5/16) VS 53. 3％ (8/15), P=0. 213]. Conclusion The choice of surgical procedure has no significant effects on the survival rate and postoperative recurrence for rectal GIST patients, and whether oral imatinib or not has no significant effects on the survival of patients.

Objective To explore the effective measures to reduce the incidence of nosocomial infection through the implementation of continuous quality improvement measures in the neonatal intensive care unit (NICU). Methods One hundred and twenty-two premature infants hospitalized in NICU of the Affiliated Hospital of Inner Mongolia Medical University after continuous quality improvement from January 2018 to November 2018 were selected prospectively as the experimental group, and 125 premature infants using routine nursing management mode from March 2017 to December 2017 were selected as the control group. The occurrence of bloodstream infection in two groups was observed. Results The incidence of bloodstream infection in the experimental group [7.4%(9/122)] was significantly lower than that in the control group [17.6%(22/125)], and the difference was statistically significant (P＝0.015). Compared with the control group, the experimental group had statistically significant differences in implementation rate of hand hygiene, average days of peripherally insterted central catheter indwelling, and antibiotic use rate and average days (P < 0.01). Conclusions The incidence of bloodstream infections in NICU can be effectively controlled through strict continuous quality improvement measures.
