The LVdP/dtmax, LVSP, AP and Vmax of the rat hearts in vivo were increased by Sophoridine ( 2 mg/kg, given to rats iv ) by 19.5, 13.1, 14.8 and 28.2% respectively. Such a positive inotropic effect lasted for more than 5 min and was statistically significant. Adrenaline (0.16 ?g/kg, iv ) could also increase the LVdP/dtmax and Vmax of the heart obviously and this action was not stronger than Sri after uses of drugs except at 0.5 min and vanished more quickly. There was an increment of MVO2I because of the increased arterial pressure within 3 min after use of Sri, which was much less than adrenaline. The present results show Sri strengthened the cardial force for longer time and affected the arterial pressure and MVO2I less than adrenaline in the rat hearts in vivo.

Objective To observe the fundus imaging characteristics of different stages of syphilitic posterior uveitis. Methods Retrospective cases series. Forty-six eyes of 32 patients with syphilitic posterior uveitis were included. There were 14 patients (16 eyes) and 18 patients (30 eyes) were assigned to acute stage group (with the course<2 months) and chronic stage group (with the course≥2 months) respectively. All eyes received the examination of indirect ophthalmoscopy, color fundus photography, fundus fluorescein angiography (FFA) and optical coherence tomography (OCT). All patients received regular anti-syphilitic treatment. Color fundus photography and OCT were followed after treatment. The fundus imaging characteristics of different stages of syphilitic posterior uveitis were observed. Results Indirect ophthalmoscopy and fundus color photography showed that in the acute stage group, there were 3/16 eyes with optic disc edema;4/16 eyes with a yellowish, placoid lesion involving the macular. There were only some pigment alterations on the fundus after treatment. In the chronic stage group, there were 4/30 eyes with optic disc hyperemia, 3/30 eyes with cystoid macular edema. After treatment, the optic hyperemia vanished gradually, but there were still some pigment alterations. The FFA images of two groups showed various vascular leakages. In the chronic stage group, patients also showed hyper-fluorescence with cystoid macular edema. The patients with course 2–3 years have more transmitted fluorescence on FFA. OCT showed that all eyes in the acute stage group had lost the ellipsoid zone, with irregular granular reflectivity of the retinal pigment epithelium (RPE) layer, 6 eyes with subretinal fluid in the macular. After treatment, the ellipsoid zone and RPE layer structure recovered gradually. In the chronic stage group, all eyes showed widespread loss of the ellipsoid zone, pigment migration and (or) cystoid macular edema. After treatment, the ellipsoid zone showed partial recovery. The outer ellipsoid zone was still discontinuous in patients with long duration. Conclusions Syphilitic posterior uveitis patients generally had normal fundus, but some cases had a yellowish, placoid lesion involving the macular. FFA showed various vascular leakages, and the chronic stage group showed more transmitted fluorescence. The major OCT change was loss of the ellipsoid zone or with subretinal fluid. After treatment, fundus showed no abnormal manifestations except some pigment alterations;the ellipsoid zone structure recovered gradually in acute stage eyes, partially recovered in chronic stage eyes.

Objective To observe the imaging features of ultra-wide field short wave fundus autofluorescence (SW-FAF) in eyes with multiple evanescent white dot syndrome (MEWDS),and analysis the correspondence to conventional images.Methods It was a retrospective case series study.Thirteen patients (14 eyes) diagnosed with MEWDS were enrolled.There were 12 females and 1 male,aged from 22 to 57 years,mean age was 34.5 years.All the eyes underwent fundus color photography,optical coherence tomography (OCT) and ultra-wide field autofluorescence (FAF).Simultaneous fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were performed in 6 eyes.The characteristic changes of SW-FAF in studied eyes were observed and compared with the images of FFA and ICGA.All the eyes were followed up every 1 to 2 weeks,with an average of 16.7 weeks.The characteristic images of SW-FAF and corresponding OCT were studied during follow up.Results MEWDS presented with numerous multiple hyper-autofluorescent spots,sized from 50-500 μm,with a vague boundary in ultra-wide field SW-FAF.These spots located mainly at the peripapillary area and the posterior pole with a confluent pattern.The lesions extended to the mid-peripheral retina as well and became more scattered.The distribution of the hyper-autofluorescent lesions in SW-FAF corresponded roughly to that of the greyish-white spots seen in color photograph and the hyper-fluorescent spots detected by FFA.It was consistent with the distribution of hypo-fluorescent spots in late-phase ICGA as well.But the number of the spot showed in FAF is much more than that in FFA,and slightly less than that in ICGA.The OCT scans through the hyper-autofluorescent lesions in SW-FAF showed impairment of outer retina.After the recovery,the hyper-autofluorescent spots disappeared with the outer retina structure repaired completely.Conclusions MEWDS presented with numerous multiple hyper-autofluorescent spots which located mainly at the peripapillary area in ultra-wide field SW-FAF.The distribution of the hyper-autofluorescent lesions in SW-FAF corresponded roughly to color photograph,FFA and ICGA in late-phase.The OCT scans through the hyper-autofluorescent lesions in SW-FAF showed impairment of outer retina.

Objective To develop a new method of immune isolation for transplanting pig islets to rat to observe the effects on diabetic rats.Method Diabetes of rat was induced by streptozotocin.Pancreas of pig was digested with type V collagenase.The pig islets were purified by density gradient centrifugation.Insulin stimulation index of the purified pig islets was evaluated.Liver of the 18 diabetic rats and 6 normal rats was exposed by operation.Capsule at one edge of the liver lobe was cut apart and separated from liver parenchyma on both sides of the lobe.An artificial cyst was constructed by a cellulose ester (CE) dialysis bag with a ball of hollow fibers in the bag,and each end of the bag was closed by a thread.Each end of the bag was stuffed into the subcapsule of each side of the liver lobe.The thread at each end of the bag was passed through a hole of the capsule at other edge of the lobe and linked to each other around the lobe to hold the artificial cyst on the liver parenchyma.Middle part of the cyst (with the ball of hollow fibers in) was put between the cuts of capsule and under the skin.The collagen solution (pH 7.4) with pig islets (4000 IEQ) was injected into the subcapsule artificial cyst of 12 diabetic rats as experiment group.The collagen solution without pig islets was injected into the subcapsule artificial cyst of 6 diabetic rats and 6 normal rats as diabetes control group and normal control group respectively.The cut was sutured.The collagen solution became a collagen gel in the artificial cysts.At 8th week of the initial transplantation,the solution with pig islets (2000 IEQ) was injected percutaneously again into the subcapsule artificial cyst of each rat of the experiment group.Rats of the three groups were raised as usual,and the levels of fasting blood glucose were measured regularly.Result The insulin stimulation index of the purified pig islets was 2.2 ± 0.2.At 1st to 8th week of the initial transplantation,the levels of fasting blood glucose in the experiment group at every time point were lower significantly than those in the diabetes control group (P＜0.01).At 13th week of the initial transplantation,there was no significant fibroplasia around the subcasule artificial cysts in the rats by visual observation.Conclusion CE dialysis bag in the liver capsule at 13th week did not show significant stimulation to the surrounding tissues.Pig islets isolated in the subcapsule artificial cyst of rats might live normally and perform hypoglycemic action.Pig islets could be percutaneously injected into the subcapsule artificial cyst.
