Objective To observe and analysis the features of images of fundus fluorescein angriography (FFA) in low-perfused retinopathy caused by cephalo-cervical peripheral vascular stenosis or occlusion. Methods The results of FFA of 27 patients diagnosed with carotid artery stenosis or occlusion by digital subtraction angiography (DSA) and examination of Doppler and vascular-pulsation were retrospectively analyzed. Result All of the patients had a delayed arm-retinal circulation duration from 20.0 to 81.08 seconds with the mean of 32.1 seconds; a delayed retinal arteriovenous filling duration from 6 to 64.0 seconds with the mean of 24.2 seconds. Delayed arm-retinal circulation duration and retinal arteriovenous filling duration in 10 cases (37.0%); microangioma, vascular wall staining, nonperfused capillary area in 11 (40.7%); and anterior ischemic syndrome in 6 (22.2%) were found. In the 6 patients with anterior ischemic syndrome, 4 cases had narrow retinal artery, segmental changes of blood stream, vascular atresia, and abnormal arterio-venous anastomosis, and 2 cases had bold vascular loops. Conclusions The main manifestations of FFA in patients with low-perfused retinopathy are malperfusion and retinal ischemia, whose degrees relate to the extend of carotid artery stenosis or atresia, and the process of the disease.Serious retinal ischemia may combined with anterior ischemic syndrome.

Their dyspnea and fatigue were evaluated with Borgrating scales, lung function were tested, 6-minute walking performance and quality of life were rated before and after the rehabilitation. ResultsThe dyspnea and fatigue decreased, 6-minute walking distance increased, and scores of quality of life improved (P<0.01) after rehabilitation,but lung function was not improved significantly (p0.05). Conclusion Health guidance from clinic nurses is able to improve the endurancecapacity and quality of life in old patients with chronic obstructive pulmonary disease.

objective To explore the correlation of single nucleotide polymorphism (SNP) frequency of adiponectin(APN)in patients with type Ⅱ diabetes(T2DM)and its complications,investigate whether the SNP is a risk factor of inheritance of T2DM,and to set up a highly efficient.accurate, economical and practical screening assay to detect the mutation of APN in clinical practice.Methods According to the diagnostic criteria of T2DM,patients with coronary heart disease(CHD),hypertension (HP),and diabetic nephropathy(NE)were recruited into this study.In simple,12DM group,T2DM-HP, T2DM-CHD.T2DM-NE and the control group.serum biochemistry items are measured.The technique of denaturing high-performance liquid chromatography(DHPLC)was used to detect SNPs of ANP gene.Results After all fragments amplified in the reglen of promoter of APN gene were compared with APN GeneID:9370 sequence recorded in GenBank,point mutation has been identified(-11377G/C).The frequency of genotypes of GG,GC,and CC are 5.16%,42.25%,52.58%and 3.4%.32.75%,63.85%,respectively in the groups of T2DM and control.The frequency of G allele was related to the incidence of T2DM,and is a risk factor of T2DM.The relative risk of GC to CC in developing T2DM is much high than that in the control group (OR=0.55).By comparing the clinical data of different groups of genotype in T2DM,it was observed that the genotype affected systolic blood pressure,BMI,abdominal circumference, and waist-buttock ratio(P=0.015).After optimizing the experimental conditions.it was found column temperature 6 0℃ was the best when using DHPLC technology to estimate SNP of APN gene.Conclusion SNP (-11377G/C) of APN gene G allele has a definite correlation with complications of hypertension in T2DM patients,and may contribute to the genetic risk for type 2 diabetes.

AIM To investigate the changes of biochemical index of osteoporosis in rats induced by given total flavonoids of herba epimedii (HEF) . METHODS The rat osteoporosis was induced by given retinoic acid intragastrically, the biochemical index in serum (T, E 2, ALP, PTH, BGP, Osteocalcin ) and in urine (Ca, P, DPD and Cr) were determined after the rats were given HEF by low, middle and high dosages respectively, and were compared with the model group. The normal control and the positive control. RESULTS The E 2, T and BGP level in all three dosage groups were obviously higher than that of the model group. The Ca/Cr, DPD and PTH level were obviously lower than the model group. The content of Ca and P and the bone density in femur were similar with the normal control, and there was significant difference compared with the model group. CONCLUSION HEF prevents the rats treated by retinoic acid from becoming osteoporosis. The changes of biochemical index were consistent with the variation of bone density, indicating the great significance of biochemical index in diagnosis and treatment of osteoporosis.

Objective To examine whether microinjectlon of morphine into the rat thaiamle nucleus submedlus (Sin) could depress the bee venom (BV)-induced nociceptive behaviours. Methods In inflammatory pain model induced by BV subcutaneous injection into rat unilateral hind paw, the inhibitory effects of morphine microinjection into thalamic nucleus suhmedius (Sin) on the spontaneous nociecptlve behavior, heat hyperalgesia and tactile ailodynia, and the influence of naioxone on the morphine effects were observed in the rat. Results A single dose of morphine (5.0 μg, 0. 5μL) applied into the Sm ipsilaterni to the BV injected paw significantly depressed the spontaneous paw flinching response. Morphine also significantly increased the heat paw withdrawal iateneies in the bilateral hind paw and the tactile paw withdrawal threshold in the ipsilnteral hind paw 2 hours after BV injection. All these depressive effects could be effectively antagonized by pre-treatment with the opiuld receptor antagonist naloxone (1.0μg, 0. 5μL) in the Sm 5rain prior to morphine administration. Naloxone alone injected to the Sm had no effect on the BV-induecd nociceptive behavior. Conclusion These results suggest that Sm is involved in opioid receptor-mediated antt-nociception in the rat with the BV-induced inflammatory pain. Together with results from previous studies, it is likely that this effect is produced by activation of the Sm-ventrolateral orbital cortex-periaqueductal gray pathway, leading to activation of the brainstem descending inhibitory system and depression of the nodceptive inputs at the spinal cord level.
