1.Recent advances in diabetic cataract advanced glycation end products and its inhibitors
Chinese Journal of Experimental Ophthalmology 2011;29(8):760-763
Diabetic cataract is an metabolic-type cataract. Its pathogenesis mechanism is not completely clear. Researches demonstrated that glycosylation plays an increasingly important role in the formation of diabetic cataract,and increased blood glucose level promote the pathogenesis and progression of diabetic disease by accelerate the glycosylation response. Therefore, more researches on advanced glycation end products(AGEs) and its inhibitors is being concerned. The advance in the study of AGEs concept, its effect on diabetic cataract formation, the influence of AGEs inhibitor on diabetic cataract are summarized in this article.

Vascular endothelial growth factor (VEGF) plays essential roles in embryonic development and angiogenesis of a variety of diseases.In recent years,the neuroprotective effect of VEGF is increasingly receiving attention.The expression of VEGF is upregulated during hemorrhagic cerebrovascular disease.It plays a protective role in cerebral hemorrhage,but its role is controversial in subarachnoid hemorrhage.The relationship between VEGF and hemorrhagic cerebrovascular disease is both close and complex.More research is needed to clarify the relationship between them and to provide new clinical ideas for the prevention and treatment of this kind of disease.

Objective To evaluate the effects of epidural capsaicin on pain threshold and nerve tissue structure in adult rats. Methods Twenty-four adult male Wistar rats weighing 250-300 g were used in this study. A catheter was inserted into epidural space at L5,6 according to the method of Philippe. 0.4 ml of capsaicin 0.1% (group A), 0.25% (group B) or 0.5% (group C) or 10% Tween 80 (control group) was injected via the epidural catheter. Pain threshold was measured by thermal stimulation of the tail before (baseline) and on the 3rd, 7th and 14th day after epidural capsaicin. The animals were then killed. The lumbar segment (L4-6) of the spinal cord and spinal nerve roots were removed immediately for light and electron microscopic examination. Results Pain threshold was significantly higher in group A, B and C than in control group (P

Objective To explore the impact of overweight and obesity on flow mediated dilation (FMD) in adult people.Methods Intact clinical data of 183 healthy people, aged 30~65 in our hosipital were analyzed.According to BMI, all people were divided into obesity group (48 cases), overweight group(75 cases) and normal group (60 cases).FMD was detected by E tracing of ultrasonic.Weight, WC, BFP, baPWV, BP,FPG,CHO,HDL-C,LDL-C,TG and UC were observed at the same time.FMD of three groups were compared and the risk factors of FMD were analyzed.Results The level of FMD in the obesity group and overweight group was significantly higher than that in the normal group[(5.63±2.76)%,(6.45±2.54)% vs.(8.31±3.04)%](F=13.77,P<0.001);there was no statistically significant difference between the obesity group and overweight group (t=1.68,P>0.05).Age(β=0.078,95%CI: 1.004,1.164),BMI(β=0.465,95%CI 1.148,2.208),LDL-C(β=2.294,95%CI: 9.918,1.612) and UC(β=0.007,95%CI 0.986,1.000) were independent risk factors of decreased FMD(P<0.05).Conclusion Age, BMI, LDL-C and UC are independent risk factors of decreased FMD.

Aquaporin4(AQP4),a member of the aquaporin family,is mainly expressed inastrocytes end-feet in the central nervous system. A large number of experimental studies have show n that AQP4 expression plays an important role in the occurrence, development, and regression of brain edema after different types of stroke. In addition, the AQP4 expression can affect the development process of cerebrovascular disease through the mechanisms such as affecting the integrity of the blood-brain barrier and promoting astrocyte migration, nerve regeneration, and neuroinflammatory response. Investigation of regulation mechanisms of AQP4 in transmembrane transport of substance in brain and intracel ular and extracel ular environmental balance and its expression in model of cerebrovascular disease have an important significance for understanding the occurrence, development, protection, and treatment of clinical cerebrovascular disease.

The distribution of glycogen, polysaccharide, mucopolysaccharide, lipid and nucleic acid has been studied in Echinorhynchus gadi(Acanthocephala). The results were summarized as follows: Glycogen and polysaccharide was demonstrated by Bauer PAS reaction technique and was found in fertilization membrane in ovum, central nuclear mass in acanthor and lemnisci, hypodermis in cystacanth. Mucopolysaccharide was demonstrated by Mowry alcian blue staining technique and was found in outer membrane, fibrillar coat, fertilization membrane and inner membrane in acanthocephalan ova. Lipid was demonstrated by Smith Nile blue stain and Lison Sudan black B staining technique and was found roughly parallel to that of polysaccharide. Nucleic acid was demonstrated by Rosenbeck Feulgen reaction, Taft methylgreen-pyronin stain and Diengdoh acridine orange staining technique and found in central nuclear mass in acanthor, also, was found in lemnisci, proboscis and hypodermis in cystacanth.

We compared the efficacy of each modality of treatment group in reducing the frequency of coronary artery abnormalities and change of clinical courses in children with Kawasaki disease in the children of 81 cases who were admitted in pediatric department of Yeungnam University Hospital from September 1985 to August 1990. Group A (37 cases)-aspirin alone, Group B (44 cases)-intravenous gammaglobulin (400 mmg/kg/day) for 5 consecutive days, plus aspirin. We studied the frequency of echocardiographic abnormalities, the duration of fever, and changes in the total white blood cell counts, platelet counts, ESR and CRP value at 1, 2 and 3 weeks of the illness and compared the results between the two groups. The results were as follows. 1) There was no significant intergroup difference in age and sex ratio. 2)The duration of the febrile period after the initiation of the therapy was significant shorter in group B (2.5±1.2days) than in group A: (5.2±3.5 days) (p<0.01). 3) No significant difference was noticed in the WBC and platelet counts in two groups as measured at admission day, 1 and 2 weeks of the illness, however, at 3weeks of illness significant difference was noted. 4) The CRP values measured at 1,2 and 3 weeks after treatment were significantly lower in group B (2.42±1.8, 2.00±1.2, 1.16±1.0) than in group A (7.22±5.3, 5.25±3.9, 1.85±1.2) respectively (p<0.01). 5) In 2D-Echocardiogram, coronary artery dilatation was more frequent in Group A than in Group B at 6month of illness (p<0.01). In conclusion, intravenous gammaglobulin therapy was effective in the shortening of the duration of fever and in the anti-inflammatory action and somewhat effective in prevention of coronary artery aneurysm.
