Retinal angiomatous proliferation(RAP) is a special type of age-related macular degeneration (AMD) with a pathological process of neovascularization.Different with several types of neovascular AMD,the new blood vessel in RAP is believed to originate from the inner retinal circulation.Because of inadequate knowledge,there still exist some limited understanding for this disease,such as its clinical diagnosis,therapy effectiveness and its poor prognosis.The newest interpretation about RAP was based on the findings of indocyanine green angiography(ICGA) and the first generation of optical coherence tomography (OCT) imaging system.The stage,histogenesis,histopathology,nature process,fundus findings,differentiating diagnosis and treatrnent of RAP were reviewed.

In this experiment, the crude Fructus Crataegi, its baked product, the products baked to dark brown and baked to charcoal were compared regarding the gastrointestinal promote function of rat, the content of free acids in stomach, total acids, pepsin and nitrite as indices. As a result, the crude and the fried product possessed greater effects on the digestive ability of rats, but their nitrite content was lower. It was preliminary suggested that adding the crude and the fried product into digestant be an optimum selection

Objective: To study and discuss the experience veteran TCM doctor KONG Si-bo in treating optical disease. Methods: To analyze the academic thoughts of KONG Si-Bo from four aspects: theory, method, formula and herbs. Results: According to differentiation of syndrome, KONG Si-bo emphasized on the entirety and treating according to three categories of disease causes. He thought that on the base of traditional eight principle differentiation, yin and yang played a more important role in differentiation. In treatment aspect, he prefered to eliminating stagnation, especially eliminating liver stagnation. As for herbs, he liked using Shigao to clear heat, and had lots of gains from learning about herbs of expelling wind, regulating qi, dissipating stasis, invigoration. Conclusions: The experience of expert KONG Si-bo in treating optical disease deserved researching and learning by other doctors.

The recombinant protein drug usually has a short half-life after intravenous (IV) or subcutaneous (SC) administration. The methods of prolonging the half-life of recombinant protein drug in common use are mainly based on three principles: 1 Amplifying the molecule weight of protein drug; 2 Making use of drug balance in the blood; 3 Reducing Immunogenicity. Three methods were focused on: Analog construction, PEGylation and Albumin fusion technology. The characteristics, half-life and immunogenicity problem of their products in the market and under development are summarized.

Objective To design the mushroom covered stent and study the primary application for gastroesophageal anastomosis thoracic cavity fistula.Methods On the base of the peculiar anatomic structure and the pathological changes of gastroesophageal anastomosis thoracic cavity fistula, we designed the mushroom covered stent. Under the fluoroscopic guidance, 6 mushroom covered stents were placed in 5 patients.Results The fistula oral of the patients with post operative perforation were closed with the mushroom covered stent, the food intake ability and nutriture of all patients were improved.Conclusions The structure of the mushroom covered stents is reasonable, which is effective and safe for treating the patient with gastroesophageal anastomosis thoracic cavity fistula.

Objective To investigate the relationship between the mutation of the exon 4 of leptin receptor gene(4Lys 109 Arg)and left ventricular function and renal hemodynamics in patients with hypertension.Methods From December 2005 to December 2006,digoxin marked primer enzyme coloration technique was used to detect the 4Lys 109 Arg polymorphism.The color Doppler echocardiography was used to detect the left ventricular function and the renal hemodynamics.The study covered 90 patients with hypertension (hypertension group)and 52 controls (control group).Results The frequencies of 4Lys109Arg in hypertension group and control group had no significant difference.The hypertension with GG genotype was significant difference in left ventrieular ejection fraction(LVEF),E/A,left ventrieular fractional shortening(LVFS),resistance index(BI),pulsatility index(PI)(P<0.05).The hypertension with GA genotype had significant difference in LVEF,E/A,LVFS(P<0.05).In hypertension group,LVEF,E/A,LVFS.RI and PI had significant difference between GG and AA genotype(P<0.05).In control goup,RI had significant difference between GG and AA genotype(0.65 ±0.02 vs 0.63±0.02,P<0.05).Conclusion The renal hemodynamics and the left ventricular function are associated with 4Lys109Arg polymorphism.

ObjectiveTo study the effects of angiogenesis on the development of endometrial carcinoma. Methods Hysterectomy specimens were stained immunohistochemically by the marker of factor Ⅷ-related antigen for endothelium vessels in normal controls, patients with endometrial hyperplasia and with endometrial carcinoma. Results The microvascular density(MVD) in tumour increased gradually from normal endometrium to endometrial hyperplasia and to endometrial carcinoma(P<0.01). MVD correlated with the mvometrial invasion, histologic grades and the stages.ConclusionMYD in endometrial hyperplasia increases. MVD can be used as a prognostic factor.

Objective To investigate the effects of Hui-hui Gan-song Yin(HGY) on the accumulation of extracellular matrix of rat glomerular mesangial cells(MCs) induced by high glucose.Methods The 40 SD rats were randomly divided into normal control group(distilled water), glurenorm group(10 mg/kg), HGY high-dose group(10 g/kg) and HGY low-dose group(5 g/kg), 10 rats in each group.The rats in each group were treated with corresponding drugs, twice a day.After 3 days, the serum containing each drug were prepared to culture rat MCs in vitro.The MCs were divided into the normal control group( 10% serum of rats in normal control group ) , high glucose group ( 30 mmol/L glucose +10% serum of rats in normal control group), glurenorm group(30 mmol/L glucose+10% serum of rats in glurenorm group), HGY high-dose group(30 mmol/L glucose+10% serum of rats in HGY high-dose group) and HGY low-dose group(30 mmol/L glucose+10% serum of rats in HGY low-dose group).The fibronectin(FN), ColⅠand ColⅣ levels were detected by Western blot.Results Compared with normal control group, the expression of FN, ColⅠand ColⅣ in high glucose group increased(P<0.01).The HCY suppressed the protein expression of FN, ColⅠand ColⅣ significantly(P<0.05).Conclusion The serum containing HGY could suppressed protein expression of FN , ColⅠand ColⅣ and inhibit the accumulation of extracellular matrix of MCs induced by high glucose, which could protect glomerulus and delay the development of diabetic nephropathy.

Objective To observe Effect of baicalin on BV2 cell activation damage caused by rotenone.Methods Rotenone infected BV2 cell viability were detected by MTT assay, and OX42 expression by ICC method assay, the inner cell Ca2 + content by fluorescence spectrophotometry, intracellular iron content by ICP-AES when low concentrations iron of load without damage in cells and extracellular H2 O2 and intracellular content of MDA, NO, NOS with related kits.ResuIts Rotenone exposure BV2 cell reduced cell viability, the expression of cell marker protein OX42 and intracellular Ca2 +content and intracellular iron content were all significantly increased(P<0.05), resulting in oxidative damage to cells.Baicalin reduced OX42 expression of rotenone exposure BV2 cell, increased cells survival, reduced intracellular iron content and H2 O2 release and oxidative damage of BV2(P<0.05).ConcIusion Baicalin inhibits BV2 activation and damage by rotenone-induced, and it has neuroprotective effects.The protection mechanism may relate to reduce iron into cells .
