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 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 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 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 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 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 establish the method for determination of methyl acrylate, methybenzene, o dimethylb, m dimethy, p dimethy and phenylethene in Kechuanning Capsules(Papaver nudicaule) by chromatography. Methods: The GC system consisted of stainless steel column, 3.5% organic bentonite and 2.5% DNP as the solid phase, nitrogen as the carrier gas, and FID as the detector. Results: The contents of all the determined substances in Kechuanning Capsules are lower than 20mg?g -1 . Conclusion: The method is sensitive, accurate and reproducible, and it can be used to control the quality of the preparation.

Objective To discuss the intervention effects and mechanisms for Rapamycin on renal interstitial fibrosis in rats.Methods A total of 72 Wistar male rats were randomly divided into 3 groups,normal group(n =24) ,model group(n =24), treatment group (n =24).The model group and treatment group received adenine 200 mg/kg daily,and the treatment group was also given Rapamycin 5 mg/(kg·d) at the 8th day,the normal group was just given the same amount of normal saline for 6 weeks.In the end of the 2nd,4th and 6th week,8 rats in each group were sacrificed respectively.The expression of hepatocyte growth factor(HGF), transforming growth factor-β (TGF-β) and neutrophils gelatinases related apolipoprotein (NGAL) in each group were observed.The software of image analysis system was used for semi-quantitative analysis.Results HE and Masson staining results showed that the renal tubular were progressive swelling, and changed with interstitial fibrosis,atrophy and even necrosis in model group from 2 weeks to 6 weeks.The pathological changes of kidney were more ease in the treatment group compared with those in model group.Immunohistochemical staining results showed that HGF expression levels of renal interstitial tissue in model group and treatment group at the 2nd week were significantly higher than those of normal group(P ＜0.05), and were significantly decreased at the 4th week and 6th week (P ＜ 0.05);HGF expression levels of renal interstitial tissue in treatment group were significantly higher than those in model group (P ＜ 0.05).NGAL expression levels of renal interstitial tissue in model group and treatment group at the 2nd week were significantly higher than those in normal group(P ＜0.05) ,and were significantly decreased at the 4th week and 6th week(P ＜ 0.05);NGAL expression levels of renal interstitial tissue in treatment group were significantly higher than those in model group (P ＜ 0.05).TGF-β expression levels of renal interstitial tissue in model group and treatment group at the 2nd,4th,and 6th week were significantly higher than those in normal group (P ＜0.05) ,while TGF-β expression levels of renal interstitial tissue in treatment group were significantly lower than those in model group (P ＜ 0.05).Conclusion Rapamycin could improve the rat kidney tissue pathology, relieve renal tubular expansion, and slow progression of renal interstitial fibrosis, and has certain protective effect to the kidney.

Objective:To study the vertical and horizontal proportions in facial area and the difference between Han and Kazak normal adults in Xinjiang area.Methods:According to certain standards,the adult Han and Kazak college students in Urumqi were randomly selected.Frontal photographs were taken for the subjects in accordance with the same standards.The data were imported into computer, and 20 standard anthropometric marks were determined,then 1 5 measurements were performed by photoshop soft ware,1 9 proportion i-tems of the mesurements was established.Independent sample t-test was applied for statistic analysis by SPSS1 9.0.Results:The face of the males was shorter and wider than that of the females.The males have smaller fissure width and bigger alar width than the females. However,the Han subjects have smaller fissure width and mouth width,bigger alar width and intercanthal width than the Kazak.Con-clusion:This study suggests that facial proportions were significantly different between the two nationalities and between sexes in Xin-jiang.
