Cardiovascular diseases are closely related to proliferation , injury and apoptosis of the cells in the cardiovascular system .For instance , endothelial cells play an important role in the pathogenic process of hypertension and atherosclerosis , and smooth muscle cells and monocytes/macrophages involve in the formation of atherosclerotic plaque . Recently, it has been confirmed that long noncoding RNA (lncRNA) regulates proliferation, apoptosis, injury, autophagy and differentiation of the cells by a series of regulatory mechanisms , thus participating in the development and progression of cardiovascular diseases .This article is to review the recent research progress on the function of lncRNAs and their regu -latory roles in the cardiovascular diseases at cellular and molecular levels .

Background Immediately ocular rinsing is a key step for the prevention of eye tissue damage after acute chemical bums.A good ophthalmic rinsing solution can neutralize chemical substance and improve the prognosis of patients.Objective This study attempted to evaluate the therapeutic effect of self-made citric aciddisodium hydrogen phosphate buffer and citric acid-disodium hydrogen phosphate-potassium chloride buffer on corneal chemical burns in mice.Methods Citric acid-disodium hydrogen phosphate buffer solution (solution 1) and citric acid-disodium hydrogen phosphate-potassium chloride buffer solution (solution2) with the pH 7.4 were prepared.One hundred and twenty clean male C57 mice aged 6-8 weeks were randomized to two groups,and filter papers containing 1 mol/L H2SO4 or 0.15 mol/L NaOH were attached to the central corneas of the right eyes to create the acid or alkali burning models.Then the eyes were immediately rinsed by 40 ml solution 1,tap water or solution 2 according to the grouping and the model eyes without rinsing served as the control group.The corneal opacity was examined by slit lamp microscope and scored in 3,7 and 14 days after modeling.The percentages of corneal fluorescein staining,corneal neovascularization and corneal ulcer were analyzed.The study protocol was approved by Experimental Animal Ethic Commission of Second Military Medical University.Results In the corneal acid burning models,the number of eye with corneal opacity scored 1 in the solution 1 group,tap water group and solution 2 group was significantly more than that in the non-rinsing group in 3,7 and 14 days after modeling (all at P＜0.01);In 3 days after modeling,the numbers of eye scored 1 were more in the solution 1 group than those in the tap water group and solution 2 group (x2 =11.000,P =0.001;x2 =4.000,P =0.046).There were no differences in the eye number of different corneal opacity scores in 14 days after acid burning (all at P＞0.05).In 3,7 and 14 days after corneal alkali burning,the number of eyes with corneal opacity scored 1-2 was significantly increased in the solution 1 group,tap water group and solution 2 group compared with non-rinsing group (all at P＜0.01).The percentage of corneal ulcer in the solution 1 group,tap water group and solution 2 group was 7％,27％ and 13％,respectively,which was significantly lower than 73％ in the non-rinsing group (P =0.000,0.027,0.003),and no significant differences were seen in various time points after corneal alkali burning (all at P＞O.05).Corneal neovascularization occurred in 50％ mice in non-rinsing group in 14 days after acid burning.However,no neovascularization was seen in the mice of the solution 1 group,tap water group and solution 2 group in both acid and alkali burning mice.Conclusions Citric aciddisodium hydrogen phosphate buffer (pH 7.4) appears to be an effective emergency rinsing solution for corneal chemical burns and the rinsing solution with or without potassium chloride is not obviously affected to the prognosis of corneal chemical burns in the mice.

ObjectiveTo assess the clinical application of endoscopic submucosal dissection(ESD) for early esophageal carcinomas and pre-malignant lesions. MethodsESD was performed for early esophageal carcinomas and intraepithelial neoplasms without submucosal infiltration. First, normal saline was injected into the submucosa to elevate the lesion from the muscle layer. Then, the surrounding mucosa of the lesion were cut, and the lesion was dissected along the connective tissue of the submucosa. ResultsOf 15 early esophageal carcinomas and intraepithelial neoplasms, ranging from 2.5 to 4.5 cm (mean size 3.2 cm) , 14 (93.3%) underwent ESD successfully . All 14 lesions were confirmed pathologically, and no basal or dissected margin was involved. The mean ESD procedure time (from fluid injection to complete dissection) was 75 min ( ranging from 45 to 150 min). Minor bleeding (mean volume 30 ml) occurred in all lesions, which was stopped by electric coagulation, argon plasma coagulation and clamps. No delayed bleeding occurred. The perforation rate of ESD was 0(0/15). Fourteen patients were followed up after ESD for 6 to 18 months (mean=11.5), and healed with no residue or recurrence. ConclusionESD is a novel endoscopic procedure to reseet early esophageal carcinomas and pre-malignant lesions, with which large lesions can be resected and pathological information can be provided.

Objective To evaluate clinical efficacy and safety of endoscopic radial incision( ERI) for benign stricture of esophageal anastomosis. Methods Clinical data of 17 patients with benign stricture of e?sophageal anastomosis undergoing ERI from October 2013 to September 2014 were retrospectively studied. Im?provement of clinical symptom and treatment?related complication or discomfort were intensively analysed. Re?sults All 17 patients successfully received ERI procedures, and the mean operating time was 10 minutes with a mean of 4 incisions. Obvious bleeding and mis?cut of normal mucosa occurred in 1 case, and this patient was cured by endoscopic hemostasis, gastrointestinal decompression and administration of antibiotics. Heartburn oc?curred in 5 patients and disappeared spontaneously without other complications or discomfort. Dysphagia score decreased from 3?11 to 0?90 in the second day after ERI(P<0?01).The mean follow?up time was 15?5 months ( range 9?20 months) . The dysphagia score showed no significant difference between the follow?up period and the second day after ERI ( P>0?05 ) . Conclusion ERI is simple, safe and effective for treating benign stricture of esophageal anastomosis.

Objective To observe the macular morphology and circumpapillary retinal nerve fiber layer thickness (RNFL) in Parkinson's disease (PD) evaluated by spectral-domain optical coherence tomography (SD-OCT). Methods A total of 37 patients (74 eyes) with PD were in the PD group, 32 age-and sex-matched healthy subjects (64 eyes) in the control group. All subjects underwent SD-OCT examination with 5 line scanning, macular cube 512×128 scanning and optic disc volume 200×200 scanning. The retinal thickness, central foveal thickness (CFT), macular volume and thickness of circumpapillary, superior, inferior, nasal, and temporal of RNFL between two groups were comparatively analyzed. The relationship between SD-OCT parameters and age, disease duration, scores of Hoehn-Yahr and unified PD rating scale (UPDRS) in PD patients was analyzed by Pearson correlation analysis. Results Both of the retinal thickness and macular volume in PD group were significantly reduced than those in control group (t=?2.546,?3.410;P=0.012, 0.001). There was no difference of CFT (t=?0.463, P=0.644) and the thickness of circumpapillary (t=?1.645, P=0.102), superior (t=?0.775, P=0.439), inferior (t=?1.844, P=0.067), nasal (t=?0.344, P=0.732) and temporal (t=?0.541, P=0.590) of RNFL between two groups. The retinal thickness, macular volume, CFT and the thickness of circumpapillary, superior, inferior, nasal, temporal of RNFL had no relationship with age, disease duration and scores of Hoehn-Yahr and UPDRS in PD patients (P>0.05). Conclusions In PD patients, the retinal thickness and macular volume are decreased, however, the circumpapillary RNFL have no obvious alterations.

Objective To investigate the changes of multifocal electroretinogram ( mf-ERG ) in patients with Parkinson′s disease.Methods Forty-five Parkinson′s disease patients ( 70 eyes ) and 35 normal controls (60 eyes) enrolled in the Second Affiliated Hospital of Soochow University from February 2015 to February 2016 received mf-ERG examination and general ophthalmology examinations including best corrected vision acuity, slit-lamp test, fundus examination, intraocular pressure and vision field test. Results The amplitude density of P 1 wave in Parkinson′s disease patients was dramatically decreased in ring 1, ring 2 and ring 5 compared with the normal controls (amplitude density of P1 in ring 1:(100.58 ± 41.19) nV/deg2 vs (138.10 ±17.16) nV/deg2,t=5.086,P<0.01; amplitude density of P1 in ring 2:(21.93 ±7.46) nV/deg2 vs (37.56 ±9.39) nV/deg2, t=9.844, P<0.01; amplitude density of P1 in ring 5:(7.07 ±3.04) nV/deg2 vs (10.22 ±3.68) nV/deg2 ,t=4.924, P<0.01).The latency of P1 wave in ring 1, ring 3 in Parkinson′s disease patients was significantly higher than the control group (latency of P1 wave in ring 1:(42.72 ±8.09) ms vs (37.90 ±5.95) ms, t=-3.155, P<0.01;latency of P1 wave in ring 3:(41.20 ±7.63) ms vs (37.80 ±4.59) ms, t=-2.995, P<0.01).The implicit time of N1 wave in ring 1 in Parkinson′s disease patients was delayed , which had statistically significant difference compared with the normal controls ((21.92 ±7.87) ms vs (19.04 ±4.19) ms, t=-2.012, P=0.046).However, in the amplitude of N1 wave, there was no statistically significant difference between the two groups . Conclusions The vision function has already decreased in Parkinson′s disease patients , even before the vision acuity is normal .The mf-ERG test can find the changes of vision function in Parkinson′s disease patients, which are the decrease of amplitude density of P 1 , the latency of implicit times of P 1 wave and N1 wave in some regions of the retina .

Objective To determine the efficacy and safety of endoscopic submucosal dissection(ESD) for local residual and recurrent lesions in digestive tract after endoscopic mucosal resection (EMR).Methods From June 2006 to November 2007, 15 patients with local residual and recurrent lesions of digestive tract after EMR underwent ESD. The procedures of ESD were as follows: normal saline was injected into the sub-to elevate the lesions from the muscle layer, and the mucosa around the lesions were pre-cut, then the connective tissue of the submucosa beneath the lesions was dissected, and the scar beneath the lesion was re-sected along the plane of the submucosa with a Hook-knife. Results The mean diameter of 15 residual and re-current lesions after EMR were 2. 3 era(0.8 ～ 3. 5 cm), of which 6 lesions were located in stomach, 3 in colon and 6 in rectunm. All cases showed negative lifting sign due to scar formation. Fourteen lesions were completely re-sected and the overall resection rate was 93.3%(14/15). It was pathologically confirmed that 13 cases showed no tumor involvement in lateral and basal resection margins, and the complete resection rate was 86.7% (13/15).The mean operation time was 87 min(ranging from 60 to 155 min). Minor bleeding occurred during ESD in all ca-ses, but there was no postoperative bleeding. Two cases had free air in abdominal cavity due to deep dissection,but recovered with conservative treatment after ESD without surgical involvement. The perforation rate was 13.3%(2/15). The mean follow-up period was 13 months and no recurrence was recorded. Conclusion ESD proves to be a novel, safe and effective procedure for local residual and recurrent lesions after previous EMR, which makes it possible to resect the lesions completely and provide precise pathological information.
