1.引言尼泊尔是一个位于印度和中国之间的内陆高山小国,面积为14.7181万(公里)~2。它拥有多样的地质生态环境,目前人口为1760万,1988年时人口年增长率为2.66％。人口增长正在向森林储量施加日益增大的压力,尤其是在丘陵地区和山区,薪柴林的日渐短缺和相关的土壤侵蚀已成为严重的问题,急需寻求迅速的对策,以维持森林和农业的生产力,以及丘陵、山区和特赖平原人民的生活质量。环境退化问题是复杂的,有时可按范围和时间这两方面分类。退化可能会集中于一个点源上,如在城市地区,或分散在广大区域之间,如毁林那种情况。在时间上。

Atypical Olfactory Neuroblastoma Presenting as Sinonasal Polyposis with Nasopharyngeal Extension: A Case Report

引用

International Journal of Otolaryngology and Head & Neck Surgery 2015年第5期4卷 394-400页

作者： Jagdish Prasad Purohit chandra Bhan Bhoopendra Singh Ajay Pratap Singh Siva Selvaraj Manish Pandey Vijay Krishna sharma Department of ENT Head and Neck Surgery MLB Medical College Jhansi India

Background: Olfactory neuroblastoma also known as Esthesioneuroblastoma (ENB) is a tumor arising from the basal layer of olfactory epithelium in the superior recess of the nasal cavity in the region of cribriform plate. Incidence peaks once in 11 - 20 years of age and again in 50 - 60 years of age. It is equally found in men and women. Aim: The main aim of this case report is to characterize the clinical features of ENB showing nasopharyngeal involvement and its importance in the differential diagnosis of sinonasal neuroendocrine malignancies. Case presentation: Two cases are reported. The first case was a 21-year-old male with symptoms of nasal obstruction, recurrent epistaxis, nasal discharge, headache and paresthesia over the face with an evolution of 1 year with no previous history of trauma. Diagnostic nasal endoscopy revealed reddish gray mass filling bilateral nasal cavities. Posterior rhinoscopy revealed mass coming through choanae and filling the nasopharynx. Endoscopic resection of tumor was done and postoperatively all the symptoms of the patient resolved. The second case was a 62-year-old male with complaints of nasal obstruction, nasal discharge, recurrent epistaxis, anosmia and difficulty in swallowing. On computed tomography, anteriorly, the mass was extending up to external nares and posteriorly up to the nasopharynx, superiorly up to nasal roof and inferiorly up to hard palate. No obvious erosion of floor of anterior cranial fossa was seen. No intracranial extension was seen. Surgery was advised but patient refused to undergo any treatment. Conclusion: This study highlights the characteristics and clinical features of ENB showing nasopharyngeal involvement and their importance in the differential diagnosis of sinonasal neuroendocrine malignancies.

Homocysteine is sulfur containing intermediary amino acid formed by the demethylation of dietary methionine to cysteine. The raised serum homocysteine level is one of the important risk factors associated with coronary artery disease. We present a 23-year-old male with no other risk factors of coronary artery disease presented to us with acute anterior wall myocardial infarction and was treated with primary percutaneous coronary intervention. During the routine work up post percutaneous coronary intervention significant elevation of serum homocysteine level was seen with markedly low serum vitamin B12 level and was treated for it along with standard therapy for acute myocardial infarction. The case illustrates the need to incorporate a plasma homocysteine level during work up of coronary artery disease especially in young patients, more importantly in those without any conventional risk factors.

Rural Institute of Medical Sciences and Research Saifai India Department of Community Medicine R. D. Gardi Medical College Ujjain India District Hospital Etawah India

Purpose: To study the prevalence of dry eye in a hospital based population of rural setup and to evaluate its association with various risk factors. Material and Methods: In this cross sectional study, patients above 20 years of age were screened randomly for dry eye. An 8 points questionnaires, slit lamp examination of meibomian glands, tear film breakup time, fluorescein staining of cornea, schirmer test were used to diagnose dry eye. The diagnosis was made when three of the five parameters were positive. The role of various occupations as well as role of different exposure factors like sunlight, excessive wind, smoking, drugs, and air pollution as dry eye risk factors was accessed. Result: Out of 445, 45.39% patients had dry eye. Dry eye prevalence was higher in those above 70 years of age (74%). It was higher in male population (51.82%) compare to female population (37.37%), nearly equal in rural (46.04%) and urban population (44.31%) and highest among factory workers (90%). Correlation of dry eye with drugs (P = 0.0002), sunlight/high temperature (P = 0.0003) and smoking (P = 0.03) were significant. Conclusion: This is a hospital based study which provides prevalence of dry eye in rural region of western Uttar Pradesh. It is more common in old age male population and significantly higher in factory workers. Out of different modifiable risk factors most important are drugs, sunlight/high temperature and smoking.

On Thermodynamic Analysis of Substances with Negative Coefficient of Thermal Expansion

引用

Engineering（科研） 2013年第11期5卷 844-849页

作者： Kal Renganathan sharma Lone Star College-North Harris Houston USA

There are reports in the literature on the discovery of novel materials that were observed to shrink upon heating. Treatment of these materials in the same manner as the materials with positive coefficient of thermal expansion can lead to the misinterpretation of the laws of thermodynamics. This is because volume expansivity is usually defined at constant pressure. Negative values for volume expansivity can be shown using Maxwell’s reciprocity relations to lead to negative values for absolute temperature for ideal gas. For real systems, using Helmholz free energy analysis at equilibrium an expression for the volume expansivity was derived. It can be seen that this expression would be always positive for real physical changes, either heating or cooling. Isentropic volume expansivity is proposed as better suited for analysis of materials with negative thermal expansion, NTE and composites used in space such as Hubble telescope and chandra telescope with zero coefficient of thermal expansion. This kind of a switch from isobaric to isentropic has precedence in the history of development of speed of sound.
