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.

Objective:To compare the effects of three root canal sealers with respect to time on biocom-patibility of human periodontal ligament cells (hPDLCs).The sealers included zinc oxide and eugenol based sealers (ZOE),epoxy resin sealers (ERS)and silicone based sealers (SBS).Methods:hPDLCs were primarily cultured,with the method combining of tissue explant and enzymatic digestion.The cells were then exposed to different extract fluids:(1)ZOE extracted for 24 h group ;(2)ZOE extracted for 1 week group;(3)ZOE extracted for 2 weeks group;(4)ERS extracted after 24 h group;(5)ERS extracted after 1 week group;(6)ERS extracted after 2 weeks group;(7)SBS extracted after 24 h group;(8)SBS extracted after 1 week group;(9)SBS extracted after 2 weeks group;(10)Dulbecco modified Eagle’s me-dium/F12(DMEM/F12)as negative control group.Cell morphology was observed under an inverted mi-croscope.Cell proliferation was measured by methyl-thiazol-diphenyltetrazolium (MTT)assay.ALP assay kit was used for measuring alkaline phosphatase (ALP)activity.Sealers of 2 weeks’setting time were then immersed in an osteogenic medium for examination of mineral nodules and calcium deposits.Re-sults:Considering the relative growth rate (RGR),ZOE was severely to moderately cytotoxic (RGR:13.6% -39.9%),while ERS was slightly or not cytotoxic (RGR:87.6% -95.3%).Only SBS did not show any cytotoxicity after setting (RGR:91.8% -106.7%).The setting time influenced the cytotoxic-ity of ERS which decreased after 1 week.Considering the ALP activity,there was no difference between SBS group and control group(F =3.397,P =0.053).According to the results of calcium deposits, ZOE:D562 nm =0.180 ±0.050,ERS:D562 nm =2.968 ±0.201,SBS:D562 nm =3.623 ±0.039,Control:D562 nm =3.477 ±0.102,the ranking of ALP activity and calcium deposits was as follows:ZOE

OBJECTIVE:To provide reference for vancomycin-induced neutropenia adverse reactions/adverse events in clinical diagnosis. METHODS:With a case of children with neutropenia treated by long-course and large-dose vancomycin,PubMed and CNKI were retrieved to collect related literature and the literature was analyzed. RESULTS:Neutropenia may be associated with vancomycin,based on causality criterion of adverse reaction in China. CONCLUSIONS:Vancomycin-induced neutropenia in chil-dren is most likely associated with prolonged exposure induced by infusion,vancomycin dosage should be reduced or stopped,and routine blood and plasma concentration should be closely monitored.

Objective To explore an optimal method of producing STZ-induced type 1 diabetic KM mice model by investigating the molded rate of single high dose and multiple low dose of STZ injection.Methods Sixty KM mice were randomly divided into 4 groups(n=15), two control groups and two model groups.In the two control groups, one was blank control and the other was negative control.Mice in the blank control group treated with no injection, but mice in the negative control group were treated with injection of citric acid salt buffer.For the two model groups, one was single high-dose group, 150 mg/kg STZ was injected only once.The other was multiple low-dose group, 50 mg/kg STZ was injected for 5 consecutive days.After the last injection, daily food and water intake were tested, blood glucose level and body weight were examined once a week for 4 consecutive weeks. Results Mice in the two model groups showed typical features of diabetes.The blood glucose levels in the two model groups were significantly higher than in the two control groups ( P <0.05 ) .For the two model groups, the molded rate of 150 mg/kg and 50 mg/kg group were 60% and 53.33%respectively at 1st week, but at the 4th week, they were 60% and 80% respectively.The mortality of these two groups at the 4th week was 33.33% and 20% respectively.Moreover, the blood glucose level in multiple low-dose group increased stably from the 2nd week to the 4th week.Conclusion The multiple low-dose STZ injection (50 mg/kg for 5 consecutive days) is an optimal method for producing KM mice model of type 1 diabetes mellitus.
