Objective To explore the effect of prospective nursing on preventing constipation for patients with acute myocardial infarction(AMI). Methods 43 AMI patients during July 2008 and June 2010 in our hospital were classified as the observation group, besides the nursing routine of the acute myocardial infarction plus routine therapy to prevent constipation, prospective nursing was implemented.Through the retrospective analysis of medical record, 41 of AMI in our hospital during March 2006 and June 2008 were classified as the control group, they were given the nursing routine of the acute myocardial infarction plus routine therapy to prevent constipation and the nursing intervention after occurrence of constipation. The defecation condition was assessed for the two groups of patients on admission and the defecation and mortality rate was compared on the eighth day of hospitalization. Results There was significant difference in constipation and mortality rate between the two groups of patients during hospitalization. Conclusions The prospective nursing for AMI patients to prevent constipation can obviously reduce the incidence of constipation, thus to avoid serious complications caused by constipation and reduce mortality.

Objective To explore the influence on college students' contrast sensitivity how dual N-back working memory training task based on Gabor,and to provide new training method for improving the contrast sensitivity.Methods 42 college students were randomly divided into three groups:a control group (17 students) ; a working memory training group (13 students) ; and a Gabor orientation training group (12 students).The control group received no training,while the working memory training group and the Gabor orientation training group received N-back working memory training and Gabor training,respectively,over three weeks (5 days a week,approx.half an hour per day).The above-mentioned two training methods performed with the same visual stimulus,i.e.,the Gabor patch with a fixed spatial frequency and contrast.The contrast sensitivity of the 42 students was measured and recorded using OPTEC6500 before and after training.Results In the working memory training group,a salient gain in contrast sensitivity was observed after the training (before:(1.48 ± 0.26) log,after:(1.87 ± 0.13)log),with a statistically significant difference (t =-6.20,P ＜ 0.05),while both the Gabor orientation training group (before:(1.75 ± 0.19) log,after:(1.68 ± 0.30) log) and the control group (before:(1.67 ±0.25) log,after:(1.61 ± 0.26) log)) showed no statistically significant difference (P ＞ 0.05) in terms of contrast sensitivity.Conclusion N-back working memory training shows a positive effect on improving contrast sensitivity in Gabor identification training,and can be used as a means to improve contrast sensitivity.

Objective To observe the growth inhibition effect of sustained-release fluorouracil implantation in nude mice with human colorectal carcinoma and to discuss its influence on caspase-3 expression .Methods The colorectal carcinoma subcutaneous transplanted model with LoVo cell in BALB/c nude mice was established and divided into 4 groups randomly :the tail intravenous injection of PBS (A group) ,the tail intravenous injection of 5-FU group (B group) ,the intratumor injection of 5-FU group (C group);and the implant of sustained-release fluorouracil group(D group) .After 15 d of medication ,the tumor weight and tumor volume were recorded ,the tumor inhibiting rates were calculated .The tumor tissues were observed by HE staining and detected the expression of caspase-3 by immunohistochemistry (IHC) .Results Sustained-release fluorouracil could suppress the transplantation tumor growth significantly ,the tumor weight and tumor volume in the D group had statistical differences compared with the A ,B and C groups(P<0 .05) ,which could up-regulated the expression of caspase-3 ,the differences between the D group with the A ,B and C groups (P<0 .05) .Conclusion Sustained-release fluorouracil can inhibit the grow th of colorectal carcinoma transplantation tumor more effectively than conventional fluorouracil and up-regulate the expression of caspase-3 ,which prompts that sustained-re-lease fluorouracil may play the anti-tumor role by inducing the tumor cell apoptosis via apoptosis pathway .Its definite tumor-inhibi-ting effect deserves to be promoted in clinical chemotherapy .

OBJECTIVE:To evaluate the utilization and tendency of calcium products and calcium absorption enhancers in our hospital.METHODS:The calcium products and calcium absorption enhancers used in our hospital from 2005 to 2007 were analyzed statistically in respect of drug variety,consumption quantity,consumption sum and DDDs.RESULTS:Compound Calcium Amino Acid Chelate Capsules and Calcium Carbonate Chewable Tablets took the lead in clinical application.Leading the list of DDDs were Compound Calcium Amino Acid Chelate Capsules(Osteoform Capsules),Calcium Carbonate Chewable Tablets and Oyster Shell Tablets Calcium,however,the old generation calcium products had gradually become out of date.CONCLUSION:The use of calcium products and calcium absorption enhancers in our hospital was rational on the whole,but there are some problems which call for attention.

Teaching in classroom is an essential pattern of clinical theoretic education. Evaluation, which is one of the most available methods to monitor and manage the teaching quality is simultaneously an effective way to build up a teaching group and train the teacher. The evaluating system should include students' opinions, companion's advice and experts' instruction. It is very important for making the evaluating more scientific, more significant and more accurate.

Objective To analyze the clinical features of pure red cell aplasia (PRCA),and to improve the recognition of its pathogenesis and treatment.Methods Among 35 PRCA patients from 1990-01 to 2003-04 in our hospital,17 patients(group Ⅰ) had immunologic abnormality,and the other 18 patients (group Ⅱ)were normal at every immunologic index.Removed the primary affection,all patients were given the combine treatment with drugs:androgen,immunosuppressive agent or/ and glucocorticoid.Results Nine patients in group Ⅰ appeared T subgroup ratio inversion in peripheral blood,eleven patients had higher level than normal with TNF?,and six patients' IL-2 level was higher.The response was 70.6%.Some patients shifted to normal in immunologic index.The response was 86.7% in group Ⅱ.But 11 cases relapsed of the 25 cured and remission patients.They responded again to the initial therapy.Conclusion Dysimmunity is the most important pathogenesis in PRCA patients.Most patients respond to immunosuppression therapy.The relapse patients also respond to initial therapy.

Objective To investigate the risk factors of the intraocular pressure (IOP) elevation after pars plana vitrectomy (PPV). Methods Eighty eight patients (88 eyes) of postoperative ocular hypertension in a series of 339 patients who had undergone PPV with normal ocular pressure before operation were retrospectively studied. The ocular pressures in both preoperative and postoperative periods were detected by NCT examination, and the ocular hypertension was decided on the level of ≥25 mm Hg. The relationships of occurence of the time of onset and duration of persistence of postoperative ocular hypertension with the different kinds of primary diseases, the techniques of operation, and the condition whether or not the affected eyes had formerly accepted surgical intervention, were analyzed. Results The IOP elevation occures mostly within 1 to 2 weeks postoperatively (77 eyes, 87.5%). In 65 cases (65 eyes) IOP returned to normal in 1 week, and in another 14 cases (14 eyes) in 1 month after treatments. Six patients' (6 eyes ) IOP was under 25 to 30 mm Hg with the medicine. With sustained elevation of IOP over 4 to 6 months, 3 cases (3 eyes ) lost or almost lost their vision finally. The probability of postoperative IOP elevation in the patients suffered from the retinal detachment with proliferative vitreoretinopathy (PVR) ≥grade C 2 was the highest in all the patients in our study (38.2%, P
