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 evaluate the value of upright standing myelography in the diagnosis of lumbar disc herniation (LDH). Methods One hundred and ninety six patients with LDH diagnosed by CT or MRI were examined by upright standing myelography before surgery. Results The most diagnosis of myelography were accorded with CT or MRI, but 7 patients of myelography with LDH at L4-5 showed compression of nerve roots, while the images of these on CT or MRI only showed disc bulge or protrusion without nerve root compression. Conclusions Myelography in the upright standing position is perhaps superior to CT or MRI for the diagnosis of LDH, especially LDH at L4-5 with nerve root compression.

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 explore the relationship between DRD2 - 141C Ins/Del polymorphism and heroin craving. Methods:380 heroin addicts who were under abstinence were given the cue- elicited heroin craving experiment. And then we detected the polymorphism of DRD2- 141CIns/Del for them by using PCR- RFLP. We compared the relationship between genotypes of DRD2- 141CIns/Del and heroin craving before and after cue exposure. Results:No significant differ- ence has been found between heroin craving before and after cue- exposure in three genotypes of DRD2- 141CIns/Del. Conclusion:D2 receptor gene - 141CIns/Del polymorphisms may have no association with the susceptibility of heroin crav- ing.

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.

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.
