Objective To evaluate the therapeutic efficacy of retrobulbar injection with triamcinolone acetonide (TA) for macular edema caused by retinal vein occlusion (RVO). Design Retrospective case series. Participants 21 eyes of 21 patients with macular edema caused by RVO. Methods Retrobulbar injection with TA 40 mg was performed on 21 eyes. The visual acuity, intraocular pres-sure, fundus fluorescein angiography (FFA) and macular central thickness under the optical coherence tomography (OCT) were recorded and analyzed before and after treatment. The follow-up duration was 6-11 months. Main Outcome Measures The visual acuity and the macular central thickness of OCT. Result Visual acuity was improved at the end of follow-up in 16 eyes (76.2%) and unchanged in 5 eyes (23.8%). Macular central thickness was (287.55±121.70) μm at the end of follow-up and (617.23±185.58) μm before treatment. The difference was statistically significant(P=0.000). After treatment, the comparison of visual acuity and macular central thickness be-tween CRVO patients and BRVO patients, as well as between ischemic RVO patients and non-ischemic RVO patients had no significant difference (P>0.05). In patients of course less than 6 months, the visual prognosis after treatment is better than that of before treatment (P=0.011, 0.01), while in patients of course more than 6 months, no difference of vision could be detected before and after treatment (P= 0.583). The result of FFA showed decrease of fluorescein leakage. During follow-up, intraocular pressure of all patients was in the nor-real range. Recurrence of macular edema was found in 8 eyes 2 to 6 months after treatment. Conclusions Retrobulbar injection with TA is a safe, effective, and easy method to treat macular edema caused by RVO. Early treatment can get better efficacy. (Ophthalmal CHN, 2009, 18: 254-256)

Objective To investigate the effect of outpatient nursing intervention in patients with chronic rhinosinusitis(CRS)on the aspects of clinical efficacy, quality of life and nursing satisfaction after medical therapy. Methods The clinical efficacy according to the judgment standard for clinical effect was valued. Medical outcome study short-form 36-items health survey (SF-36) was used to assess the quali?ty of life of the subjects. Satisfaction Questionnaire was used to evaluate the satisfaction scale of patients. Eighty subjects with CRS were randomly divided into the control group (40 cases) and the trial group (40 cases). The trial group was given nursing intervention on basis of usual nursing. In three months after treat?ment, the data and statistics analysis was purely descriptive by SPSS 20.0. Results Clinical efficacy:in the group, nineteen subjects were cured,fourteen subjects were improved and inefficacy occurred in seven subjects. The effective rate was 77.5%(31/40). In the trial group, twenty-six subjects were cured,twelve subjects were improved and inefficacy occurred in two subjects. The effective rate was 95.0%(38/40). There were differences in general data between the two groups (χ2=5.165,P=0.023). Quality of life:the average score of the control group was 58.10±5.04, while the average score of the trial group was 72.22±5.63, the average score of quality of life in the trial group was significantly higher than that in the control group(t=3.08,P=0.025). Nursing satisfaction:there were significant differences in nursing satisfaction between the control group and the trial group (u=-7.048,P=0.000). Conclusions Outpatient nursing intervention can improve the effect of patients with chronic nasal sinusitis after medical therapy, improve the quality of life and improve nursing satisfaction.

Objective To investigate the effect of pantoprazole (proton pump inhibitor, PPI) and gefarnate (gastric mucosa protectant) on the prevention of upper gastrointestinal bleeding in patients undergoing post-percutaneous coronary intervention (PCI) dual anti-platelet therapy.Methods This research included 1263 patients taking enteric aspirin and clopidogrel after PCI.The cases were divided into 4 groups: routine treatment group (n=332), PPI group (n=318), gastric mucosa protectant group (n=299), and PPI+gastric mucosa protectant group (n=314).A follow-up for 6 months was observed including gastrointestinal symptoms, upper gastrointestinal bleeding, major adverse cardiac events (MACE), and adverse reactions.Results There were 52 cases of upper gastrointestinal bleeding within 6 months, including 21 cases from routine treatment group, 9 from PPI group, 15 from gastric mucosa protectant group, and 7 from PPI+gastric mucosa protectant group.The incidence of upper gastrointestinal bleeding among the 4 groups within 6 months was statistically different (X2=8.883, P=0.031).The routine treatment group had significant higher rate than the PPI group and the gastric mucosa protectant group (P<0.05), while among other groups there was no significant difference (P>0.05).The upper gastrointestinal bleeding occurred within 3 postoperative months in 34 out of 52 cases (65.4%).There was no statistical significance among the four groups in regard to bleeding occurrence time (X2=4.212,P=0.648).Conclusions Patients undergoing post-PCI dual anti-platelet treatment can reduce the incidence of gastrointestinal bleeding by taking pantoprazole or combined with gefarnate.Intervention against upper gastrointestinal bleeding should start on the first day after PCI and last for a minimum of 3-6 months.

Objective The objective was to look for cocaineand amphetamine-regulated transcript peptide(CART) receptors or proteins interacted with CART.Methods A cDNA library from rat brain was constructed.Then the BacterioMatch two-hybrid system was used to screening for proteins interacted with CART by using CART41-102 as bait.Results The cDNA library and bait pBT-CART41-102 were constructed successfully.The library harvested 3.37?106 individuals,and the reconstruction rate was 98.5%.5.01?106 cotransformed clones were screened,93 clones were conformtively identified to interacting with CART and were DNA sequenced.By bioinformation analysis,6 known proteins interacted to CART were identified.Other unknown interaction proteins with short exactly similiar motif to 22 membraneproteins or receptors were also identified.Conclusion CART might interact to proteins for energy balance,cell proliferation and enzymes related to protein processing and degrading.

AIM:To investigate the mechanism responsible for albumin microbubbles adherence to activated leukocytes. METHODS: In vitro studies were performed in which activated or nonactivated leukocytes were incubated with albumin microbubbles and observed under microscopy. The suspensions of leukocytes and microbubbles which contained or absented of integrins were analyzed with flow cytometry.RESULTS: A minimum of 50 cells were identified under transillumination. 5 min after microbubbles were incubated with leukocytes, the number of cells interacting with microbubbles was greater for activated cells than for nonactivated cells(20 30?2 67 vs 4 50?1 43, P

To investigate a key strategy of the total synthesis of salacinol. Methods: A simplified analogue of salacinol (1),1-(3-sulfooxypropyl)tetrahydrothiophenium inner salt (2) was designed and synthesized by a coupling reaction between tetrahydrothiophene (THT) and 3-iodopropanol (3-IPA) followed by the esterification of the resulting sulfonium with sulfur trioxide pyridine complex (SO3*Py). Replacement of the alkylating reagent (3-IPA) of THT led to the predominate formation of a undesirable cyclic compound,2,2-dioxo-1,3,2-dioxathiane (7). Resutls:This model experiments indicated that the tandem synthetic process leading to the sulfonium sulfate 2 could be applied for the total synthesis of salacinol (1) as an alternative method.

Objective To explore the higher dangerous factors,the early clinical performances and its contents of neonatal pulmonary hemorrhage(NPH).Methods The clinical performances,chest radiograms and autoptical pathological materials of 66 cases of newborns who died of NPH at our neonatal department during 1993 to 2003 were reviewed and analyzed.Results The higher dangerous factors of NPH were premature delivery/low birth weight,serious diseases lead to hypoxia and severe infections.The early clinical performances of NPH were the suddenly aggravation of dyspnea and the increasing of moist sounds.The early X-ray performances were lower penetrance of lung fields extensively and well-distributly with path clouds,the intercostals space usually increased.According to the autoptical(patho)-logy,this X-ray perfomance indicated the edema of the pulmonary with small amount of hemorrhage.Conclusion The patients with the higher dangerous factors and the early clinical performances of NPH,must be diagnosed and interfered it as early as possible to reduce the mortality of NPH.
