The teaching material library of nutrition and food hygiene was established based on the concept of integrable ware.This paper discussed on the methods and the experiences.The establishing principle must be clear,knowledge points should be separated into parts accurately,courseware and other computerized teaching materials should be made into full use and convenient and efficient retrieval method must be established.In the future,teaching material library and platform construction should be improved and study of educational technology should be strengthened to improve teaching quality and adapt to modern teaching requirements.

Radioimmunotherapy (RIT) is one kind of targeted immunotherapy. It is a better therapy of tumour treatment for its distinct advantages. Nowadays, it has been widely used to treat lymphoma, and part of solid tumors. In this review,basic research and clinical application related to solid tumor are summarized.

Purpose To detect and isolate cancer stem cells ( CSC) in fresh specimens of primary and metastatic carcinoma tissues from 10 cases of colorectal cancer to study the biological functions and mechanisms of migrating cancer stem cells. Methods Suspen-sions of primary and metastatic colorectal cancer cells were labeled with antibodies CD133-PE and CD44-FITC, and then flow cytometry was used to detect and isolate the CD133-PE-positive and CD44-FITC-positive cells. Results There were certain percentages of CD133-positive and CD44-positive cells present in primary and metastatic colorectal cancer and the proportion of CSC in metastatic colorectal cancer was higher than that in primary cancer tissue (P<0.05). Conclusions There are CSC in both primary and meta-static colorectal cancer and the proportion of CSC in metastatic colorectal cancer is significantly higher than that in primary cancer tis-sue, suggesting that CSC play an important role in the metastasis of colorectal cancer.

Neoplastic stem cell (NSC),cells with stem cell properties,which out of control of proliferation properties can be formed cancer.It plays an important role in the neoplasm metastasis,and its mechanism throughout the tumorigenesis,development and prognosis.

The plasma arginine vasopressin (AVP) level was measured by RIA in 19 patients with polyuria and polydipsia, and the AVP measurement was compared with indirect tests. The AVP levels were very low in 13 patients with central diabetes insipidus and normal in 6 patients with primary polydipsia. The direct assay was correspondent to the indirect criteria in 89% of the patients. We concluded that the use of AVP assay improves accuracy in the differential diagnosis of polyuria, and is important in the diagnosis of these diseases.

The rodipicolinate synthase gene was cloned from Nicotiana tabacum L.cv,which encodes the key enzyme in the synthesis of lysine,and then a vitro molecular reform reliefing feedback suppression was made. Some resistant seedlings were acquired using the mutated gene as selectable marker and analog of lysine as selectable reagent,and the detection results were positive by means of PCR and Real-Time PCR,however the phenotype is somewhat abnormal.

Objective To compare the effect and safety of propofol with intranasal dexmedetomidine in analgesic enteroscopy for children.Methods Ninety children undergoing analgesic enteroscopy were ran-domly assigned to 3 groups.Intranasal dexmedetomidine followed by propofol was administered in the observ-ing group;sufentanil and followed by propofol was intravenously given to the control group A;propofol was given to the control group B.The scale of anesthetic effect,HR,RR,MAP and SpO2 30 min after intranasal administration were monitored.The intranasal sedation satisfaction rate,the dose of propofol,wake-up time, hospitalization,hemodynamics,adverse reaction and complication after anesthesia were recorded.Results Intranasal sedation satisfaction rate of the observing group was 83.3%(25 /30).The anesthetic effect in ob-serving group(excellent/good /bad:24 /6 /0)showed no significant difference from that in the control group A (excellent/good /bad:25 /5 /0),but better than that in the control group B(excellent/good /bad:12 /14 /4) (P <0.05).The amount of propofol in the observing group(96.2 ±5.3)mg showed no significant difference from that of group A(93.7 ±4.6)mg,but less than group B[(121.1 ±4.9)mg,P <0.05].The time of re-covery of infants in the control group A[(14.2 ±5.5)min]and the control group B[(13.7 ±3.9)min] were longer than that in observing group[(7.9 ±4.1)min,P <0.05].The hospitalization time of observing group[(14.3 ±5.4)min]was shorter than those of group A[(27.5 ±3.7)min,P <0.05]and group B [(26.3 ±6.6)min,P <0.05].The incidences of breath suppression,glossoptosis,nausea and dizziness were the lowest in the observing group,compared with the two others (all P <0.05).Conclusion In-tranasal dexmedetomidine combined with propofol,increasing children compliance,decreasing the adverse reaction,is satisfactory and safe for children anesthesia.
