1.Applications of ultra-wide-field fluorescein angiography in the diagnosis and treatment of retinal diseases
Chinese Journal of Ocular Fundus Diseases 2017;33(1):90-92
Ultra-wide-field fluorescein angiography (UWFA) is a novel breakthrough in ocular fundus imaging technology, which can capture a single, high-resolution, 200° wide image of the ocular fundus that traditional fluorescein angiography cannot reach. This technology has important impacts on the screening, diagnosis, staging, treatment and follow-up of vascular diseases involving peripheral retina (such as diabetic retinopathy, age-related macular degeneration, retinal vein occlusion, uveitis and so on).

Objective To evaluate the effects of single long stent and multiple contiguous stents for the therapy of the long coronary lesion. Methods According to the different means of stent implantation,64 cases of patients are divided into two groups:Group A for the single long stent,and Group B for the multiple contiguous stents. All of patient received coronary artery angiography in order to evaluate the rate of restenosis after 6~10 months. Results In hospital period, no acute or subacute thrombosis, no myocardial infarction and death occured. There was no difference for the restenosis rate of the stents between two groups. Conclusion The effects of both the single long stent and the multiple contiguous stents is similarity.

Objective To study the relationship between endothel in-1 in plasma and TCD in patients with brain injury.Methods We measured dynamically the level of ET-1 in plasma on 33 adult brain injured patients. Cerebral vasospasm was detected by transcranal Doppler sonography (TCD).Results 1.During 6-8 days, 13-15 days after injury,there was a significantly positive correlation between the level of ET-1 in plasma and cerebral vasospasm (r=0.533,P=0.002;r=0.423,P=0.02),especially during 6-8 days after injury. The increase of the level of ET-1 in plasma paralleled paroled with the time of cerebral vasospasm developed. 2.During 6-8 days after injury, the level of ET-1 in plasma of patients with cerebral vasospasm was obviously higher than those without cerebral vasospasm obviously (P

Objective To evaluate the advantage of laparoscopic total mesorectal excision (TME) and the clinical value of pull-through anastomosis in the treatment of rectal carcinoma. Methods From November 2005 to December 2006, laparoscopic TME combined with pull-through anastomosis was carried out on 8 patients with rectal cancer. Results In all of the 8 patients, TME was completed under a laparoscope without additional incision, and the pull-through anastomosis was performed by hand.The mean operation time was 220 minutes (range, 180 to 300). The patients were followed up for 8-18 months (mean, 13 months), during which none of them developed implantation at puncture sites or local recurrence. Conclusions Laparoscopy provides a direct, magnified and reliable view for TME. Pull-though anastomosis is a convenient and low-cost method.

Objective To observe the effectiveness of treating essential thrombocytosis(ET) with Buyang Huanwu Decoction plus hydroxyurea. Methods 120 patients with ET were randomly divided into observation group(OG) and control group(CG). Patients from OG were treated with Buyang huanwu decoction plus hydroxyurea, while those from CG were given hydroxyurea. After 6 months, the treatment effectiveness indexes including symptoms in a sense of chinese medicine, cell counts and saffy were observed. Results Total effective rate of OG was higher than that of CG(P<0.05). TCM symptoms remission in OG group was better than that of CG(P<0.05). After treatment, blood platelet count and megakaryocyte count were decreased in two groups(P<0.05), and the difference between two groups was signiifcan(P<0.05). Conclusion The therapy combined Chinese and western medicine deals with ET is better than simple western medicine treatment.

Objective To investigate if the cell death in hippocampus can occur after single and kindled audiogenic seizure,and the pertinent mechanisms involved. Methods HE staining was used to show the distribution of the dead cells and the immunocytochemistry was used to show the expression of the apoptosis\|related proteins Bcl\|2 and Bax. Results After single audiogenic seizure,there were a few dead cells in hippocampus.After kindled seizure a lots of pyknotic,acidophilic cells were found in hippocampal CA\-1,CA\-2,CA\-4 subregions and the granular layer of dentate gyrus.The CA (corrected optic density) values of Bax immunoreactivities in CA\-2 and CA\-4 subregions were increased significantly in kindled rats, in contrast with that in control rats.Conclusions\ Audiogenic kindling can induce marked cell death in hippocampus.Apoptosis may be one of the mechanisms underling this kind of cell death.

Objective To investigate the biological function of NS5ABP37 and to look for proteins interacting with NS5ABP37 protein in hepatocytes. Methods We constructed bait plasmid expressing NS5ABP37 protein of hepatitis C virus (HCV) by cloning the gene of NS5ABP37 protein into pGBKT7, then the recombinant plasmid DNA was transformed into yeast AH109 (α type). The transformed yeast AH109 was mated with yeast Y187 (α type) containing liver cDNA library plasmid in 2×YPDA medium. Diploid yeast was plated on synthetic dropout nutrient medium (SD/-Trp-Leu-His-Ade) containing X-α-gal for selection and screening. After extracting and sequencing of plasmids from positive (blue) colonies, we made a sequence analysis by bioinformatics. Results We screened twenty-five proteins binding to NS5ABP37, including Homo sapiens cyclin Ⅰ (CCNI) gene, Homo sapiens matrix metallopeptidase 25 (MMP25) and Homo sapiens talin 1. Conclusion The yeast-two hybrid system is an effective method for identifying hepatocyte proteins interacting with NS5ABP37 of HCV. And the biological function of NS5ABP37 may be associated with glycometabolism, lipid metabolism and apoptosis.

Objective:To study the face profile difference between the Han and Kazak normal youths.Methods:College students of Han and Kazak aged 18-22 years,including 152 Han subjects(58 males and 94 females)and 155 Kazak subjects(62 males and 93 fe-males)in Urumqi were randomly selected.Profile photos were taken for every subject in accordance with same standards respectively. The data were import into computer.Photoshop software was used for measuring the profiles.Independent sample T test was applied for data analysis by SPSS 19.0.Results:Lip protrusion of the males was larger than that of the females and tip of nose was more upward in the females than that in the males in both Han and Kazak subjects.However,the Han subjects have more protruding lips,smaller chin and more upward nose tip compared with the Kazak subjects.Conclusion:This study suggests that there were significant differences of face profile between the two nationalities and sexes in Xinjiang.
