AIM:To observe the image features of Vogt-Koyanagi-Harada disease (VKH) and multiple central serous chorioretinopathy (CSC) by fundus fluorescein angiography (FFA) and optical coherence tomography (OCT).METHODS:Thirty-two eyes of 17 patients with VKH and thirty-five eyes of 30 patients with multiple CSC were collected from 2009 to 2016 in my hospital.RESULTS:All the eyes with VKH were found small and dense fluorescein leakage in the early stage.The 17 eyes (53%) with VKH were found fluorescein accumulation in the final stage;24 eyes (75%) with VKH were found high fluorescence of optic disc.All of eyes with multiple CSC were found multifocal leakage in the early stage.And 2 eyes (6%) with multiple CSC were found high fluorescence of optic disc.There were 28 eyes (14 patients) with VKH and 25 eyes (22 patients) with multiple CSC had been done OCT in my hospital.Retinal pigment epithelial fold was only found in VKH.Fluctuation of internal limiting membrane (ILM) and membrane structure had higher sensitivity to diagnostic VKH from to multiple CSC, with sensitivity of 54% and 68% respectively.CONCLUSION:There are some similarities as well as differences between FFA and OCT in diagnosis of VKH and multiple CSC.A combination usage of FFA and OCT can be more effective in distinguishing VKH from multiple CSC.

Objective To evaluate the clinical efficacy of 5-aminolevulinic acid-induced photodynamic therapy (ALA-PDT) in the treatment of condyloma acuminatum. Methods Thirty-six cases of condyloma acuminatum were treated with ALA-PDT. Results After the treatment, 33 (91.67%) patients were cured, 35 (97.22%) improved. Relapse occurred in 3 (8.33%) patients. Side effects were noted in 2 (5.56%) patients. Conclusions ALA-PDT is a relatively simple, effective and safe treatment with a lower recurrence rate for condyloma acuminatum, especially for small skin lesions or lesions at specific area. However, the high expense required for multiple treatments with ALA-PDT may restrict its application.

Objective To compare and explore impact of subclinical hypothyroidism on metabolic risk factors of type 2 diabetes mellitus.Methods A total of 204 inpatients with type 2 diabetes mellitus.The patients were divide into two groups according to whether complicated with subclinical hypothyroidism:combination of simple type 2 diabetes mellitus (150 cases) and type 2 diabetes mellitus with SCH group(54 cases),two groups of age,gender,duration were no statistical difference.and collecting the clinical data of two groups of patients by Professional people,detection of blood lipids,glycated hemoglobin (HbA1c),uric acid (UA),Oral glucose tolerance test (OGTT),insulin and C peptide releasing test were taken in all groups.The improvement of insulin,C peptide index [HOMR-islet(CP)] and whole body insulin sensitivity index (ISIcomp) were used to estimate insuhn sensitivity,and improvement of insulin,C peptide secretion index [HOMR-isle (CP)] was used to evaluate the function of pancreatic islet β cell.T test was used for statistic alanalysis.Risk factors of type 2 diabetes mellitus with microvascular Complication by using Logistic regression analysis.Results (1) Compared with type 2 diabetes mellitus group,blood pressure,body mass index (BMI),triglycerides(TC),Low density lipoprotein cholesterol (LDL-C),UA,fasting C peptide(C-P0),postprandial 120 min C peptide(C-Pm),HOMA-IR(CP) were increased (P ＜ 0.05),while fasting blood glucose(FPG),bloods glucose in postprandial 120 min (G120),HbA1c,ISI-comp were decreased (P ＜ 0.05).(2) The incidence of diabetic nephropathy was higher in diabetic patents with subclinical hypothyroidism than those without subchnical hypothyroidism,the difference was statistically significant (P ＜ 0.05).(3) Logistic analysis showed that duration,SBP,TSH were the major risk factors of type 2 diabetes mellitus with nephropathy (P ＜ 0.05).Conclusions Type 2 diabetes mellitus patients with subclinical hypothyroidism compared to pure insulin resistance is more obvious,the degree of lipid metabolism disorders more severe.Elevated TSH can predict the occurrence of diabetic nephropathy in type 2 diabetes mellitus.

In recent years, the discovery of thousands of long non-coding RNAs ( lncRNAs) has certainly changed human′s view of the complexity of mammalian genomes and transcriptome, as they play an important role in the regulation of transcription, post-transcription as well as epigenetic level, widely involved in various physiological process and diseases.Here this review summarized the lncRNAs associated with cancers, discussed the established methods used to detect and quantify lncRNAs, and evaluated the clinical application of lncRNAs as biomarker.

Objective To study the serum levels of progastrin-releasing peptide (pro-GRP) and neuron-specific enolase (NSE) for the clinical diagnosis,therapy monitoring and survival time analysis of small cell lung cancer (SCLC).Methods All 41 SCLC samples (30 males,11 females,age range from 46 to 78 years),95 NSCLC samples (55 males,40 females,age range from 42 to 88 years),and 127 normal individuals samples (80 males,47 females,age range from 35 to 78 years) which were diagnosed by People's Hospital of Zhengzhou from May 1,2008 to April 30,2011 were collected.Serum levels of pro-GRP,NSE and their changes in SCLC patients before and after therapy were evaluated.ANOVA analysis,randomized block design analysis of variance and the log-rank test were collected SPSS 16.0 to evaluate the survival time.Results The serum levels of pro-GRP (median 357.8 ng/L) and NSE (median 89.5 μg/L) in SCLC group were significantly higher than those in the NSCLC group (pro-GRP:39.9 ng/L;NSE:11.43 μg/L) and normal individuals group (pro-GRP:12.7 ng/L;NSE:10.03 μg/L) (P=0.000).The sensitivity of pro-GRP and NSE for the diagnosis of SCLC were 80.4％ and 78.0％,while the specificity were 92％ and 87％,respectively.There is a poor correlation between pro-GRP and NSE serum levels,but when combined the sensitivity can be 95％ and specificity can be 85％.Significantly statistical difference of pro-GRP levels was observed in the different stages of treatment (before and after therapy) in SCLC-LD patients (F =3.53,P =0.038),and significant statistical difference of NSE levels was also observed in SCLC-ED patients in different stages (F =16.049,P =0.000).In partied response SCLC patients,the group with NSE level lower than cut-off value had longer survival time than the other group with NSE level higher than cut-off value (P =0.001).Conclusions The sensitivity of the combined analysis of pro-GRP and NSE is better than single marker for the diagnosis of SCLC.The serum level of pro-GRP has better correlation with therapeutic effect of SCLC-LD patient than NSE.The serum level of NSE are well correlated with therapeutic effect in SCLC-ED patients.There are some certain value of NSE level for evaluation the survival time of SCLC patients who were in partial response.

Objective: To build up rabbit models of hepatic cirrhosis in through common bile duct partial ligation (CBDPL). Methods: Male New Zealand rabbits were subjected to CBDPL to induce hepatic cirrhosis. The liver biopsies were performed during the surgery and after sacrifice to evaluate hepatic fibrosis. The serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), total protein (TP) and albumin (ALB) were determined at week 0, 1, 2, 4 and 11 following the occlusion. Results: There were two kinds of morphological and histological manifestations after CBDPL, the one was inconspicuous hepatic fibrosis coexisted with sacculation-like bile ductal dilation and muddy stone; the other is remarkable hepatic fibrosis and cirrhosis along with uneven bile ductal dilation. The serum levels of ALT, AST, TBIL and DBIL were significantly higher after one week of operation. The levels of ALT, AST, TP and ALB decreased after two-week of operation, and the levels of TBIL and DBIL were returned to the normal level after two-week of operation. Conclusion: The animal models of hepatic cirrhosis can be built up through CBDPL in rabbits.
