Purpose To investigate the effects of intervention with Tanakan on anterior ocular segment in diabetic retinopathy (DR) after retinal photocoagulation. Methods Prospective random controlled study was performed on 72 patients (72 eyes) with ultrasound biomicroscopy (UBM),by obtaining and quantitatively analyzing the changes of anterior ocular segment including anterior chamber, anterior chamber angle, ciliary body and choroids before and the 3rd day and the 7th day after retinal photocoagulation. Results Three days after photocoagulation, significant elevated IOP and narrowed chamber angle were observed in control group and 4 eyes (11.11%) in Tanakan group (P

ObjectiveTo investigate the diagnosis and trea tment of ankle impin gement syndrome (AIS). MethodsThirty-six cases of AIS encoun tered between March 1995 and May 2001 entered the study. Hereinto, open removals of involved soft tissue were performed in 14 cases after MRI examinations, and arthroscopic exam inations and removals were accomplished in 22 cases. Results Follow-up for 6 mo nths～7 years (mean, 22 months) in all the 36 cases revealed “excellent” outco mes in 9 cases, “good” in 19 cases, “fair” in 7 cases, and “poor” in 1 cas e, showing “good” or “excellent” results in 77 8% of the patients (28/36). ConclusionsArthroscopic examination and operation for AIS is effective.

Objective To explore the effects of transplantation of endothelial progenitor cells(EPC)from autologous bone marrow for hindlimb ischemia in diabetic rabbit model,and the difference between diabetes and nondiabetes.Methods Rabbits were randomly allocated into three groups for transplantation therapy,PBS control group(n=8,A group),EPC transplantation with diabetes group(n=14,B group),EPC transplantation without diabetes group(n=8,C group).Diabetic rabbit model was established by injecting alloxan,and hindlimb ischemia was induced by complete excision of femoral artery.Diabetic rabbits with hindlimb ischemia were therapied by transplanted ex vivo expanded EPC,and then effects were assessed by capillary density and capillary to muscle fiber ratio,and VEGF in muscle was also determined.Results Capillary density,capillary to muscle fiber ratio,and VEGF in muscle increased significantly in EPC transplantation group with or without diabetes after transplanting 14 days(P

To study time and dose related changes after gamma knife radiosurgery (GKR) in rat brain, right caudate nucleuses of rats were irradiated by OUR XGD gamma units. The maximum dosages of 20,50,75 and 160Gy were given using a 4 mm collimator. HE, Nissl, Luxol fast blue staining and immunohistochemistry were utilized to observe histological changes.Histological changes in the right caudate nucleuses such as microvessel injury, which appeared as telangiectasia, vasodilatation, vessel wall thickening and edema, and astrocyte changes, which appeared as hypertrophy and proliferation, were observed at various time points after GKR. These findings demonstrate time dependent and dosage dependent changes are found in normal cerebral tissue after GKR. These results provide an explanation of the process taking place during the latent period before delayed radiation necrosis develops.

Objective To develop the Chinese version of the 35-item Medical Outcomes Study HIV Health Survey (MOS-HIV) and to assess the reliability and validity of MOS-HIV among HIV-infected individuals.Methods Between April and July of 2007,a croas-sectional survey of 758 HIV-infected individuals was conducted.Responses to the MOS- HIV were analyzed for its reliability and validity.Results Pearson's correlation coefficients of items for test-retest relia- bility ranged from 0.46-0.92,all internal consistency reliability coefficients exceeded 0.69,and all items were more strongly correlated with hypothesized scale than any other scale.Eight scales of MOS-HIV were significantly associated with CD_4 cell counts.Conclusions The Chinese version of MOS-HIV offers good reliability and validity and can be used as a tool to assess the quality of life of HIV infected individuals in China,thus providing evidence for further studying AIDS related quality of life in this country.

OSCE is an examination of objective evaluation of the clinical skills.This article introduced the development of OSCE at home and aboard,and compared the difference of the exam setting in America,England,Canada and China Medical University.The advantages and disadvantages of SP in OSCE were also analyzed.It was discussed that OSCE would be widely applied in China.

Objective To investigate the early influences of laser photocoagulation on macular retinal thickness in diabetic retinopathy(DR). Methods Optic coherence tomography examination was performed in 30 eyes with DR(phase Ⅲ~Ⅳ) before, and on the 3rd day and the 7th day after photocoagulation respectively. The thickness of neuroretina and pigment epithelium were measured in the areas of fovea macula and 750 ?m from fovea macula. Results Three days after photocoagulation, significant thickening of neuroretina was observed in the fovea macula, which is positively related with age, fasting blood sugar and duration of DR. There was no significant changes in the thickness of pigment epithelium in macula and in the thickness of neuroretina 750 ?m from fovea macula. Conclusion Significant thickening of neuroretina in fovea macula in DR early after photocoagulation reveals progressed macular edema induced by photocoagulation which is positively related with age, fasting blood sugar and duration of DR.

Case based learning ( CBL ) teaching method was applied to the experiment group in radiology internship teaching,and conventional teaching in control group.Two mentors would evaluate and score their radiological case analysis.The aim of this research was to explore the application and effect of case-based learning ( CBL ) teaching method in radiology internship teaching.

Objective Discussion transurethral holmium laser treatment of ureteral orifice cyst and stones efficacy and safety . Methods A retrospective analysis of 23 cases of transurethral holmium laser treatment in patients with ureteral orifice cysts and stones (minimally invasive group) and 11 cases of open surgical excision of the cyst and stone -treated patients (open group), two groups were compared operative time, blood loss , catheterization time, hospital stay, postoperative complication rate .Results Minimally invasive surgery patients time (20.0 ±5.6)min, blood loss (15.0 ±2.3)ml, ambulation time (10.0 ±2.5)h, catheterization time (2.3 ± 0.2)d, length of hospital stay (5.0 ±0.6)d; open group of patients were (90.0 ±10.3)min, (80.0 ±12.7)ml, (48.0 ±5.3)h, (7.0 ±1.1)d, (11.0 ±1.7)d, two groups of indicators differences were statistically significant ( P <0.05).Postoperative complica-tions occurred in patients with minimally invasive group was 8.6%, down from 45.4% in the control group, the difference was statisti-cally significant ( P <0.05).Conclusions Transurethral holmium laser treatment of ureteral orifice cysts and stones with less trau -ma, less bleeding, shorter operative time, rapid recovery, the advantages of the low rate of complications , treatment of ureteral orifice cysts and stones safe and effective method .

PurposeTo explore and compare subtracted and unsubtracted volume rendering process on DSA apparatus in the diagnosis and treatment of intracranial aneurysms, and to provide a better reconstruction in clinic.Materials and Methods Twenty-seven patients with subarachnoid hemorrhage (SAH) underwent rotational cerebral angiography and 19 cases with embolization treatment underwent rotational cerebral angiography follow-up. 3D volume unsubtracted reconstruction and subtracted reconstructions were used respectively. Two sets of 3D volume reconstruction images were observed and analyzed by two neuroradiologists to compare the detection rate, image quality and post-embolization follow up.Results Thirty-three intracranial aneurysms were identiifed in 27 cases with SAH underwent three-dimensional digital angiography (3D-DA). False positives were found in 2 cases. 3D-DSA detected 33 intracranial aneurysms with no false positive case. There was no statistical signiifcance in intracranial aneurysms detection rate (χ2=1.943,P>0.05). There was no statistical significance in image quality of two reconstruction methods (Z=-1.445,P>0.05). In 19 cases with embolization treatment underwent the follow-up of rotational cerebral angiography, 3D-DA detected 3 cases with aneurysm remnants, while 3D-DSA detected 10. There was statistical signiifcance between 3D-DA and 3D-DSA when detecting aneurysm remnant (χ2=5.729,P<0.05).Conclusion Aneurysms can be well detected with better image quality by 3D-DSA and 3D-DA in the diagnosis and treatment of intracranial aneurysms. 3D-DSA can display more information on tiny vessels, and is better in detecting aneurysm remnants.
