Retinal artery occlusion (RAO) is an ocular emergency.Inappropriate therapy results in visual loss.Visual loss caused by RAO occurs as a result of loss of blood supply with the inner retinal layers.We reviewed a number of therapies that have been used in the treatment of RAO,including vasodilators,reducing intraocular pressure,neuro regulation,ocular fundus laser,surgery,etc.Thrombolytic therapy may result in an increased risk of intracranial and systemic hemorrhage,while the intravenous use of thrombolytic therapy should be within a window of time.At the same time,it is noticed that patients with RAO may have a risk of cerebral stroke and other vascular conditions.The risk factors for RAO are same as to atherosclerotic risk factors in stroke and heart disease,and these tactors must be actively evaluated to prevent further medical comorbidities.

This paper reports the technique to develop a disposable screen-printing base carbon electrode for the utilization in the study of enzyme electrode. The silk fibroin was applied to immobilize the mushroom extracted protein, which contained abundant polyphenol oxidase, on the surface of base electrode when it was chemically moldified by ferrocene. The voltammetric current of this enzyme electrode responded to the concentration of substrate such as catechol or dopamine. The linear range is from 2.0× 10-8 mol/L to 2.0× 10-2 mol/L, it reaches to a 95%steady value of current within less than 30 seconds, and the RSD equals to 2.7%. The service life of this enzyme electrode is at least 10 days and it will be preserved for a longer period at a humid and cool condition. All of these performances of the enzyme electrode make clear that its commercial development would be very possible.

Objective:To investigate the effect of oxaliplatin inhibit the growth in glioma U 87 cells by regulating PI3K/Akt sig-nal pathway.Methods:The glioma U87 cells were cultivated in vitro ,using 0,20,40,80 μg/ml oxaliplatin treated U87 cells 24,36, 48,72 h respectively,MTT was used to detect cell proliferation.Using 40 μg/ml oxaliplatin treated U87 cells 48 h,flow cytometry was used to detect cell cycle and apoptosis .Cells apoptosis protein and PI 3K/Akt pathway protein expression after 40 μg/ml oxaliplatin treated U87 cells 48 h was detected by Western blot .Results:MTT assay showed that compared with the 0μg/ml treatment ,oxaliplatin treatment could significantly inhibited U 87 cell survival ( P<0.01 ) ,40μg/ml oxaliplatin treatment 48 h ,the survival inhibitory was the most obvious.U87 cell cycle was arrested in S phase after 40 μg/ml oxaliplatin treatment 48 h.After 40μg/ml oxaliplatin treatment 48 h,compared with the 0 μg/ml treatment,U87 cell apoptosis rate significantly increased (P<0.01).Western blot showed that after 40μg/ml oxaliplatin treatment , anti-apoptotic factor Bcl-2 expression had significant decreased , pro-apoptotic factors Bax , Cleaved-caspase3 protein expression had significantly increased (P<0.01).PI3K,p-Akt expression was significantly decreased (P<0.01),and Akt expression had no significant change in Akt pathway (P>0.05).Conclusion:Oxaliplatin may suppress U87 cell proliferation,ar-rest cell cycle,and promote apoptosis by inhibit PI3K/Akt signaling pathway.

OBJECTIVE:To prepare solid dispersion for increasing solubility of quercetin METHODS:Using polyvinyl pyrrolidone(PVP) as the carrier,solid dispersion of quercetin was prepared by solvent -volatilization method The solubility of the solid dispersion was detected IR spectrometer and UV spectrometer were used to investigate the physical and chemical properties of the solid dispersion RESULTS:The solubility of solid dispersion was significantly increased compared with quercetin and the physical mixture Quercetin existed as ultrafine crystalline or molecular form in solid dispersion,so there was no chemical reaction between quercetin and PVP CONCLUSION:PVP could be used as the carrier of solid dispersion to increase the solubility of quercetin in water

OBJECTIVE:To establish a method for determination of the content of quercetin in quercetin-PVP solid dis?persions.METHODS:The detection wavelength for dertermination of quercetin content was set at374nm.RESULTS:The caliberation curve was linear in the range of5.0～25.0?g/ml(r=0.9998).The average recovery was99.12%,RSD=0.70%(n=6).CONCLUSION:This method is stable,quick,accurate and simple,and is suitable for quality control of quercetin in quercetin-PVP solid dispersions.

1 cm. Postoperative pathological findings showed negative cut surface. No hemorrhage or bile leakage were seen after operation. The abdominal drainage tube was indwelled for 3~4 d. The postoperative hospital stay was 3~5 d. Follow-up checkups for 1~20 months (mean, 12.5 months) revealed no tumor recurrence or incision implantation. All the patients survived. Conclusions Laparoscopic regular hepatic left lateral lobectomy can be carried out safely and effectively in clinically selected patients.

Objective To investigate the effect of prevention and treatment of venous injury caused by intravenous infusion of Delisheng with anisodamine gel.Methods 100 patients with intravenous infusion of Delisheng were randomly divided into the experimental group and the control group,50 patients in each group,and the skin at the top of transfusion puncture points of the patients of the experimental group were evenly embrocated with 2% anisodamine gel along the vein before 3 to 5 minutes of intravenous infusion of Delisheng,while the control group received no treatment.After observing the situation of venous injury,the skin at the top of transfusion puncture points of the positive patients was embrocated with 2% anisodamine gel,and the effect on venous injury was observed.Results The incidence rate of intravenous pain of the experimental group was 4%,there wasn't any occurrence of poor intravenous infusion or swelling of the infusion position.The incidence rate of poor intravenous infusion of the control group was 34% and phlebitis incidence rate was 42%,and intravenous pain incidence rate was 68%.All the venous injury symptoms of 39 patients of the control group and 2 patients of the experimental group disappeared after treatment.Conclusions The embrocating of 2% anisodamine gel can effectively prevent and treat the venous injury caused by intravenous infusion of Delisheng.

Objective To investigate the prevention and cure effect of anisodamine gel on phlebitis caused by intravenous infusion of KLT. Methods 96 patients with intravenous infusion of KLT were divided into the experimental group and the control group, 48 patients in each group, and the skin at the top of transfusion puncture points of the patients of the experimental group was evenly embrocated with 2% anisodamine gel along the vein before 3 to 5 minutes of intravenous infusion of KLT, while the control group was without any treatment. After observing the situation of venous injury, the skin at the top of transfusion puncture points of the positive patients would be embrocated with 2% anisodamine gel. The incidence, degree of phlebitis and treatment effect were compared between the two groups. Results The incidence rate of phlebitis of the control group was 68.7%, of which grade II, III occupied 60.4%, while the incidence rateof phlebitis of the experimental group was 10.4%, in which there was no occurrence of grade II, III phlebitis. All the venous injury symptoms of 33 patients of the control group and 5 patients of the experi -mental group disappeared after treatment, and after statistical processing, the incidence rate of phlebitis in the experimental group and the control group showed significant differences. Conclusions The embrocating of 2% anisodamine gel can effectively avoid the occurrence of the phlebitis caused by intravenous infusion of KLT.
