Saliva and samples containing saliva were regarded as a kind of potential biological trace evidencefor individual identification in forensic science practice. In this paper, the authors have studied theDNA analysis of saliva and saliva containing samples. The results demonstrated that DNA can be extracted from saliva and saliva-containing samples. RFLPs analysis by DNA fingerprinting and PCRbased typing can be performed according to the amount of DNA extracted from these samples.

Nursing management is an important part of hospital management,the head nurses,as leaders and organizers of first-line clinical nursing work of the hospital,play a decisive role in hospital nursing management.As the first-line managers and organizers,the head nurse management level and ability is directly related to the hospital nursing quality and the overall quality of nurses.The implementation of the performance appraisal and management by objectives in current nursing management has been more and more used in the hospital.This article aimed to review the management by objective and quantitative assessment home for head nurse at home and abroad,in order to help nursing managers to learn and master performance appraisal of head nurses,comprehensively improve quality of head nurses,promote the improvement of nursing quality,and push the development of nursing course.

The improvement of electrophoresis for DNA fingerprinting has been carried out. The time of electrophoresis was shortened,and 1/3-1/2 of reagents were saved. The minimal amount of DNA samples for DNA analysis was 0.8?g. It is worthy to popularize and apply in practice.

Teaching of Critical Care Medicine faces several challenging issues includingcomprehensive intensive or specialist intensive, approach of curriculum, tralning of team working ability, building of teaching platform and teaching staff. Critical care medical education requires the concept of viewing the discipline as a whole. Under its guidance and with the opportunity of critical care medical subspecialties building, critical care medical education should focus on bothcompre-hensive critical care and specialist critical care, and have rational planning of Critical Care Medicine course. Through the construction and integration of ICU, we should create a comprehen-sive clinical practice platform of critical care medicine to carry out clinical practice and team work tralning. Meanwhile, construction of quality critical care medicine faculty should be based on its pro-fessional features.

Objective To evaluate the clinical feature of malignant ameloblastoma. Methods A review of 25 cases of malignant ameloblastoma was presented with respect to age, sex, primary site and times of recurrence, site and time of metastasis, results of follow up, pathological type. Results Male patients outnumbered female patients by 1.5 to1. The median age at which the primary tumor was first treated was 30.5 years. The primary sites were mandible(17), maxilla(5), tibia(1), rib(1), ulna(1). The most metastases were found in lung(80%), with cervical lymph nodes and liver each representing 24% and 12% of the metastatic sites. Other sites of metastasis included brain(1), femur(1), thoracic spine(1), spleen(1), myocardial(1), mediastinum(1). The median times of primary recurrence was 2.5 times. The median survival time after metastasis was 2 years. There were four pathological types which were follicular type(4), plexiform type(2), acanthomatous type(1), granular type(1). Conclusins Multiple recurrences developed in most of the 25 patients. The time between diagnosis of primary tumor and appearance of metastasis in 25 patients was long. The most frequent sites of metastasis was lung and cervical lymph nodes. Early adequate resection of the primary tumor to avoid repeated surgical intervention is advocated to prevent tumor spread.

Background The diseases of neuro-ophthalmology are common,which can influence the quality of patients' life seriously.The 39-item National Eye Institute Visual Function Questionnaire (NEI VFQ-39) is an instrument to assess self-reported visual impairment in studies of vision.However,until now,no studies have been performed to specifically assess the vision-related quality of life in persons with diseases of neuro-ophthalmology.Objective To evaluate vision-related quality of life for neuro-ophthalmology inpatients through the NEI VFQ-39,for the better treatment and nursing for them.Methods Ninety-seven neuro-ophthalmology inpatients were scheduled in research from June 1 to September 30,2012,and we collected all the clinical datas and the Chinese version NEI VFQ-39.The NEI VFQ-39 subscale item scores were compared among subgroups divided by monocular or binocular incidence,diseases and best corrected visual acuity(BCVA),and correlation analysis of the NEI VFQ-39 scores and BCVA for better-seeing and worse-seeing eyes was performed.Results The mean age of scheduled patients was (36.6±14.4)years,with no difference in gender.The mean composite score of VFQ-39 was 57.36(46.50,73.38),mental health subscale score was lowest [45.00 (35.00,60.00)].In the four eye diseases groups,except for eye pains,degree of dependence,periphery vision,anterior ischemic optic neuropathy (AION) group had lower scores compared with the other three groups,but there were no statistical significances among the four groups (all at P＞0.05).Except for eye pains,patients with monocular incidence had better scores than those with binocular incidence,with statistical significant significances between them(all at P＜0.05).Patients with BCVA in the better-seeing eye ＞ 20/32 had better scores than the other two groups,compared with the BCVA in the better-seeing eye ＜20/200 group,except for overall health and eye pains,cornpared with the 20/200 ≤ BCVA in the better-seeing eye ＜20/23 group,except for eye pains,social activity and color vision,and the rest subscale scores had significant differences among the three groups(all at P＜0.05).NEI VFQ-39 scores had positive correlations with the BCVA for better-seeing and worse-seeing eyes,and had strong correlations with the BCVA for better-seeing.Conclusions Neuro-ophthalmology diseases have serious influences on patients' visual function and quality of life.The quality of life has direct correlation with BCVA,so improving their visual function is helpful to their quality of life.

With the rapid development of cell biology and biological materials, the dentine-pulp complex regeneration research has gone further. Scaffolds play important roles in the construction of tissue engineered dentine-pulp complex. At present, scaffolds used in dentine-pulp complex regeneration include not only natural biological materials and synthetic biomaterials, but also various composite materials and cell- or body-based carrier materials. In this paper, the latest research status of various scaffolds for dentine-pulp complex regeneration were reviewed. The advantages and problems of these scaffolds were analyzed. The future development direction was predicted.
