作为新办地方性本科院校,和其他本科院校相比,新乡学院在办学经验、师资力量等方面还存在着一定的差距.只有认清自己的优势和劣势,不断探索新的办学路子,总结实践经验,并以质量工程建设为主要任务,学校的办学质量才能得到有效的提高.本文以新乡学院机械类专业的质量工程建设为例,在如何利用质量工程建设促进办学质量方面进行了积极的探索. 相似文献

To evaluate the therapeutic effects of Rong Shuan Jiao Nang (RSJN) on treatment of acute mountain sickness (AMS) and high altitude myocardial ischemic syndrome in workers in Yushu,three groups were studied: group A (60 patients with AMS,given RSJN),group B (15 patients with altitude myocardial ischemic syndrome, given RSJN),and group C (control,without drugs). All studied subjects were lowland workers who were first time entry to Yushu for work at an altitude of 4 250 m. During the course of treatment,a routing physical examination was performed,AMS Lake Louise Scores were estimated,arterial oxygen saturation (SaO2),electrocardiography and hemoglobin concentration were measured before and after using RSJN for 10 days. In group A,the effective rate was 68 %,symptomatic improvement in 54 cases (90 %) within 5 days. In group B,the effective rate was 93 %,episodes of angina pectoris stopped in 12 patients within 3 ~ 7 days,one lasted 8 days. After treatment, the level of SaO2 increased 15.5 %,21.8 % and 5.6 % in group A,group B and group C,respectively. RSJN taken at the start of the arrival at Yushu can decrease AMS scores and facilitate cure. If taken after the illness has begun,RSJN may help lessen symptoms,especially effectively improved angina pectoris of the high altitude myocardial ischemic syndrome. Symptoms usually subside after 3 ~ 8 days. RSJN should be continually used for at least 7 days after ascent. 相似文献

A new type of dendritic polymer, named dendronized hyperbranched polymer (DHP), was prepared successfully by the macro-monomer approach. Thanks to the perfect 3D isolation effects, DHPG1 exhibited good NLO property with d 33 value of 133 pm/V, higher than its analogues of dendronized polymer and dendrimer, and its stability of NLO effect was also enhanced. 相似文献

N-cadherin is related to the progression and metastases of several solid carcinomas. However, it was still unclear whether N-cadherin is overexpressed in colorectal malignant tumors that have stronger malignant tendency. In this study, we used immunohistochemistry to detect the expression patterns of N-cadherin in both the primary tumors and their normal mucosa tissues of 120 patients with colorectal cancer. We revealed that N-cadherin was expressed in 78.3% (94/120) of colorectal tumor tissues and in only 9.2% (11/120) of paired distant normal mucosa tissues with a significant difference (P=0.000). The low, moderate, and high expression of N-cadherin protein was 42.5%, 30.8%, and 26.7%, respectively. N-cadherin overexpression was associated with advanced TNM stage, lymph nodes metastasis and distant metastasis (P<0.05). Patients with N-cadherin overexpressed showed the obvious lower overall survival rate than those with moderate and low expression, and patients with low expression had a better survival rate than those with moderate and high expression (P<0.05). In conclusion, high N-cadherin expression may lead to tumor aggressiveness and metastatic potential in colorectal cancer, and may prove to be a possible prognostic factor. 相似文献

This paper presents a novel method that integrates the Algebraic Connectivity Strength of Point(ACSP) and Scoring Criteria to identify genes associated with tumor type.First,for each gene,the ACSP is used to identify reliable expression levels of the gene in all the samples.The informative genes are then selected using Scoring Criteria based on these reliable expression levels.Finally,the Support Vector Machine(SVM) classifier is used to classify the two datasets of gene expression profiling.The results show that the informative genes selected by the proposed method have higher credibility than those selected by Scoring Criteria alone. 相似文献
