Objective To review the causes of exudative retinal detachment(ERD),indications of vitrectomy for ERD and its outcomes.Design Retrospective case series.Participants 57 patients with ERD received vitrectomy in EENT Hospital,Fudan Uni- versity.Methods A retrospective analysis of clinical records were conducted.Main Outcome Measures Etiology,vitrectomy indica- tions and its outcomes.Results 57 cases(62 eyes)with ERD received vitrectomy.The disease distribution of vitrectomy were Coats dis- ease in 23 cases(45.2%),familial exudative vitreoretinopathy in 8 cases(12.9%),uveitis in 7 cases(11.3%),retinal hemangioma in 7 cases(11.3%),bullous retinal detachment in 6 cases(9.7%),endophthalmitis in 4 cases(6.5%)and pit of optic nerve in 2 cases(3.2%). Severe ERD and proliferative change were major indication for treatment with vitrectomy.During follow-up period,most patients gained useful vision in early stage.Follow up rate of 6 months or more was 64.9%.The recurrence of ERD was 5.4% and most patients also gained useful vision.Condusion Coats disease is the prominent cause of being treated with vitrectomy in ERD.When proliferation or vitreous hemorrhage happens or macula is involved,vitrectomy should be performed.Most patients can gain useful vision after vitrecto- my.(Ophthalmol CHN,2008,17:52-55)

Objective To find out nutrient support drug utilization in cancer patients in our hospital. Methods An analysis was made by means of drug utilization research into the structure and rationality of nutrient support drug utilization in our hospital through an investigation into the detailed records of the dispensary from 1999 to 2002 and into 1 014 medical records from 2002. Results The variety, quantity, and cost of nutrient support drug utilization in the four years rose respectively by 58.82%, 71.66% and 28.16%. 49.30% of the cancer patients whose medical records were surveyed used such drugs. The quantity and person time ratio of PN and EN drug utilization was respectively 14∶1 and 13∶1, with malnourished patients accounting for 19.80%. Of the PN drugs whose DDD value could be determined, most had a DUI value that was greater than 1 whereas most of the EN drugs had a DUI value which was smaller than 1. Conclusion The variety, quantity, and cost of nutrient support drug utilization in the four years rose rapidly. The quantity and person time of PN drug utilization were much higher than those of EN drug utilization. Doubts could be cast in the handling of indications for nutrient support drug utilization in some patients and the doses of some nutrient support drugs prescribed were not so rational. Further explorations need to be made into the rational application of nutrient support treatment.

At present, China’s OTC market is developing fast and would become the largest medicine market of the world. Medicine production enterprises explored China’s market one after another. Facing up such fierce competition, it’s an arduous task for inland OTC medicine production enterprises to get market share. It analyzes the necessities and misunderstandings of China’s OTC medicine production enterprises, studies the countermeasures for China’s OTC medicine production enterprises to conduct CIS strategy by analyzing characteristics of OTC medicine and market situation.

AIM: To observe the clinical efficacy of adjunctive intravitreous injection with Lucentis for the treatment of neovascular glaucoma ( NVG) .
METHODS:The retrospective case series study included 25 eyes of 25 patients who underwentintravitreous injection with Lucentis. Patients firstly received an intravitreous injection with Lucentis (0. 5mg/0. 05mL), after the regression of neovascularization of the iris, patients accepted different surgical treatments according to different etiopathogenesis condition. Iris, chamber angle neovascularization condition, intraocular pressure, and visual acuity were observed postoperatively. The follow-up duration was 3mo.
RESULTS:After 3-7d of intravitreous Lucentis injecting, iris and chamber angle neovascularization was totally faded in 20 cases (20 eyes) and was not completely faded in 5 cases ( 5 eyes ) . Additional treatments were compound trabeculectomy ( 14 cases, 14 eyes ) , vitrectomy ( 4 cases, 4 eyes ) . The patients' mean intraocular pressure was 43. 42 ± 10. 99mmHg before treatment, which decreased rapidly when they came out of the hospital (14. 26±7. 64mmHg, P<0. 05) and stabilized during the follow-up 3mo (18. 76±5. 96mmHg, P<0. 05). Follow-up at 3mo, visual acuity improved or remained in 20 cases ( 20 eyes ) and decreased in 5 cases ( 5 eyes ) . The complete success, qualified success and failure were 21 eyes, 3 eyes and 1 eye, respectively.
CONCLUSION:Intravitreous injection with Lucentis can be used as an assisted treatment of NVG. According to different etiopathogenesis condition, it is an effective treatment to combine with other treatment methods for NVG.

Hyperhomocysteinemia is an independent risk factor for arterial and venous obstructive vascular di-seases. Raised plasma homocysteine concentrations are caused by genetic and non-genetic factors. The pathogenic mechanism is not clear. It may be associated with endothelium dysfunction, abnormal lipid metabolism, hypertrophy of intima media, increased platelet aggregation and several clotting factors interfered, etc. The metabolism and pathogenic mechanism of homocysteine are reviewed in this article, which provides theoretical foundation for the treatement of hyperhomocysteinemia.

Objective To evaluate the clinical application of GlideScope~ video laryngoscope in anesthetic endotracheal intubation.Methods Two hundred patients who received surgery under general anesthesia with ASA I or II were involved in this study.One hundred patients were assigned to be intubated with GlideScope~(GS group) and the other 100 with size 3 Macintosh laryngoscope(ML group).The following data were recorded and analyzed: noninvasive blood pressure(NBP),heart rate(HR) at the different time points of intubation process,glottic exposure time,CormarkLehane grade,tracheal intubation time and total intubation attempts. Results The rise of NBP and HR in ML group were significantly higher than those in GS group(P

To investigate the inhibitory effects of siRNA expression vector on proto-oncogene Pokemon expression in SW480 cells and to provide experimental basis for further research about the biological function of Pokemon.siRNA expression vectors were constructed to express a short hairpin RNA against Pokemon.The recombinants were transfected into SW480 cells with liposome.Cellular morphology and transfection efficiency were observed.The expression of Pokemon were checked by real-time fluorescence quantitative PCR and Western blot.MTT assay was used to detect the effect of siRNA on the growth of SW480 cells and Fluorescence Activated Cell Sorter was applied to study cell apoptosis of SW480 cells.The transfection efficiency was about 36% and the cellular morphology changed greatly at 48h after transfection.siRNA expression vectors could specifically reduce the expression of Pokemon mRNA and protein in SW480 cells.Compared with negative control,the inhibition ratio of Pokemon mRNA expression was 34.2% and 67.7%,in 24th hour and 48th hour,the inhibition ratio of Pokemon protein was 48.3% and 73.6%,in 48th and 72th hour,respectively.Transfection with Pokemon siRNA expression vectors could inhibit cell growth and induce cell apoptosis of SW480 cells.siRNA expression vectors were successfully established that could effectively inhibit the expression of Pokemon in SW480 cells.Pokemon gene silencing could decrease growth and increase apoptosis of SW480 cells.

With the deterioration of environment, and the excessive collection of wild resources, the wild populations of Myla- bris phalerata Pallas are less and less, almost extincted in many traditional distribution areas. It is necessary to breed M. phalerata artificially for sustainable utilization. Food preference of adult M. phalerata is the key to its provenance screening and domestication in the artificial breeding. In this paper, the food preference of 3 geographical populations of M. phalerata was studied. The results showed that the food preferences of adult M. phalerata in different geographical populations were different. The adult M. phalerata in Wuming preferred cucumber flowers, gourd flowers and melon flowers. The adult M. phalerata in Tianlin preferred cowpea flowers. And the adult M. phalerata in Guangzhou preferred cowpea flowers and gourd flowers. Gourd flowers were the most attractive food for the adult M. phalerata of 3 geographical populations of M. phalerata.
