Background
Ischemic stroke or cerebral infarction in young adults (20-50 years) is relatively frequent, accounting for
more than 10%-26% of all first strokes and its incidence rises steeply with age. Causes of “Young stroke”
are heterogeneous and while it generally has a good prognosis, it has a significant socioeconomic
impact, including functional deficits and financial costs. The most frequent causes of cerebral infarction
in young adults are cardio-embolism, hypertension, premature atherosclerosis, migraine, smoking and
hypercoagulable states.
Objective
The aim of this study was to compare characteristics of cerebral infarction between young (20-49 years)
and old (50-89 years) patients undergoing investigations and treatment according to one common
protocol in the tertiary hospital.
Methods
This Descriptive case series study was conducted in Department of Neurology of First State Central
Hospital from October 2014 to July 2016. During this study, we observed 220 patients with first-onset
of cerebral infarction from which 90 young patients (under 50 years) and 130 old one (above 50
years), based on prospective study. Data regarding the etiology and risk factors of the stroke, clinical
manifestations, and diagnostic test results of patients were examined during their hospital treatment as
well as a NIHSS, modified Rankin Scale scores, and Barthel Index at admission and discharge, also
at 21 day. Stroke subtyping was conducted in accordance with the Trial of Org 10172 in Acute Stroke
Treatment (TOAST) criteria.
Results
In total, 220 patients with cerebral infarction were included, from which 90 (40.9%) were 20-50 years
and 130 (59.1%) were 50-89 years. The proportion of males was higher among both groups: 61.1% vs.
70.0%. Common causes for cerebral infarction in the young patients were current smoking (53.3.1% vs.
37.8%), long-term alcohol consumption (51.1 vs. 12.3), cardiac embolism (36.0% vs. 16.2%), migraine
with aura (25.5% vs. 12.2%), infective diseases (15.6% vs. 0.8%), and oral contraceptive use (14.4
vs. 0%). Leading causes for ischemic stroke in old patients were the conventional risk factors such as
hypertension (75.4% vs. 38.9%), atherosclerosis (66.9% vs. 31.1), coronary artery disease (24.3% vs.
12%), and diabetes mellitus (26.9% vs. 6.7%). Most of the young stroke patients demonstrated good
functional outcomes, at the time of discharge (71.1% vs. 60%) and three weeks (86.6% vs. 66.2%)
patients had Rankin Scale scores in the range of 0-2.
Conclusions
There are significant differences between young and old patients with cerebral infarction regarding to risk
factors, etiological subtypes and improvement of functional deficits associated with the stroke. However,
severity of stroke on admittance is similar but three weeks outcome is different among young and old
patients with relatively rapid improvement of functional deficit in young stroke patients than old one.

The Mongolian plants considered to possess medicinal properties may contain novel compounds since they are exposed to severe conditions; such plants could become good candidates for modern drug discovery programs. Daurian Thermopsis (Thermopsis lanceolata R.Br.= Th.dahurica Czefr.), Gobian Thyme (Thymus gobicus Tschern.) and Mogilev Mallow (Malva mohileviensis Downer) are separately used as mucolytic and anti-inflammatory treatment in non-conventional medicine. Therefore, weprepared extract of these herbals compound called as a Tetima and to evaluate it’s acute toxicity. It isimportant to produce mucolytic effective new pharmaceutical preparation used for upper and lowerrespiratory tract inflammatory disease.Tetima herbal compound extract was prepared in ethanol, the ratio of herbals to ethanol was 1:10. Healthy 25 white albino mice (male weighing between 17-30 gram) used in this study. They were kept in large airy cages in groups of 5 animals per cage with free access to food and water. Five doses (8-20 g/kg) were then chosen for the determination of intraperitoneal LD50 in mice and given to five groups of albino mice. The animals were observed for first 2 hours and then at 6th and 24th hour for any toxicsymptoms. After 24 hours, the number of deceased mice was counted in each group. The percentage of animals that died at each dose level was transformed and then LD50 determined by the methods of Karber and Pershin.G.N.The LD50 of Tetima herbal compound in mice was determined to be 14.3 g/kg after intraperitonealinjection. There was no difference occurred between Karber and Pershin methods to evaluate acute toxicity. In the animals receiving intraperitoneal injection, the abdominal muscle contractions and ataxia was observed, which persisted for few hours. At the 6th hour they were drowsy and less responsive. The severity of these effects was related to the level of dose. However, at 24th hour most of the survivors had recovered from these symptoms.Tetima herbal compound extract is a relatively safe, particularly when given intraperitoneal inject toexperimental animals.

BACKGROUND. Since the implementation of Pre-medical curriculum the first students have successfully finished their courses. However, formative and summative evaluation of the curriculum hasn’t been done. The purpose of this study is to analyze the correlation between satisfaction level and knowledge acquisition of the students.
MATERIAL AND METHODS. The study was completed at School of Bio-medicine of MNUMS and Division of Education and Policy. We have studied correlation of grade point average (GPA), integrated final exam score, and general admission test/entrance examination test scores (Chemistry and Biology test scores) of total of 395 students’.
RESULTS. A total of 395 students’ 4 types of test scores have been used in this study. Out of 395 students, 68 (17%) male, 327 (83%) female and 317 (80%) medical and 78 (20%) health sciences pre-medical students. Results have shown that, both general admission test score and university pre-medical GPA had a direct, average line correlation. In other words, students who have had a higher general admission test score; have scored higher GPA scores at university. The comparison of GPA with the integrated final exam score has shown a direct, average line correlation, which proves the validity of the GPA.The highest factor among was the teacher methodology skills scoring 4.0. The lowest factor was teaching facilities and student lesson load scoring 3.7.
CONCLUSION. The satisfaction level is higher the average. The student GPA, general admission test score, both have a direct or average line correlation.

Abstract
Malaria is an ancient disease caused by parasites of the genus Plasmodium and transmitted by several species of female anopheline mosquitoes. The term „malaria‟ originates from mal’aria (Italian) –signifying „bad air‟ or miasmas arising from marshes.
Cognizant of the burden of the disease in antiquity, several efforts have been made to understand the disease notably, the detection of the Plasmodium parasite in the blood of infected humans in 1880, as well as proof of the complete life cycle of malaria parasites in mosquitoes in 1897.
Among 200 Plasmodium species identified P. falciparum, P. vivax, P. ovale, P. malariae and P. knowlesi are known to be responsible for human malaria, while mortality due to malaria is mostly attributed to infections with P. falciparum.
The Anopheles mosquito bites a human and injects sporozoite forms. These move to the liver and invade hepatocytes, in which they develop to produce exoerythrocytic merozoite forms that are released into the blood stream. Merozoites invade erythrocytes and grow into trophozoites and
mature schizonts. Merozoites are released that reinvade new erythrocytes.
Gametocytes, formed from the asexual blood stage, are taken up by a feeding mosquito into the gut where they mature to form male and female gametes. The fertilized zygote develops to an ookinete and an oocyst and finally sporozoites that migrate to the salivary glands.
Malaria transmission exits in 99 countries throughout world, and the greater burden of the disease is carried by African countries. According to the World Health Organization (WHO), the estimated cases
of and deaths due to malaria in 2016 were 219 million and 660,000, respectively with malaria deaths steadily decreasing since 1980. Despite the decline in the burden of malaria with the scaling-up of interventions the fact that the estimated (uncertainty exists) number of malaria deaths in 2016 exceeded that of 1980 calls for more efforts in the prevention and control of the disease.
Mongolian troops have been participating at UN mission since 2003. They work very complicated condition. One of the simple risks is Malaria. We had approximately 80 cases who had been
infected by malaria at the mission area.
Mongolia is land without malaria infection. But our tourists can visit all of the world and troops works on mission area in Africa. They have a risk of malaria and our doctors have to be diagnosis and treat to
malaria cases. This article provides an overview of malaria laboratory diagnosis and epidemiological data that will lead to the development of strategies to diagnose and reduce infection.

Proteomic tools were used to identify the key proteins that might be associated with bronchial asthma(BA). Firstly, the serum samples from healthy adults and asthmatic patients were collected. Tandem Mass Tag~(TM)(TMT), which removes high-abundance structures and nonspecific proteins, was employed to identify the differentially expressed proteins between asthmatic patients and healthy adults. Gene Ontology(GO) annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were carried out for the differentially expressed proteins. The core proteins in the asthma group were screened out by protein-protein interaction(PPI) analysis. Then the core proteins were verified by Western blot for 3 patients with bronchial asthma and 3 healthy adults. A total of 778 differentially expressed proteins were screened out, among which 32 proteins contained quantitative information, including 18 up-regulated proteins and 14 down-regulated proteins. The differentially expressed proteins were enriched in 28 KEGG signaling pathways. The PPI analysis showed that 10 proteins(GDN, 1433 Z, VWF, HEMO, CERU, A1 AT, TSP1, G3 P, IBP7, and KPYM) might be involved in the pathogenesis of bronchial asthma. Compared with those in healthy adults, the expression levels of SLC25 A4, SVEP1, and KRT25 in the sera of asthmatic patients were up-regulated(P<0.05). Therefore, it is hypothesized that a variety of immune signaling pathways and differentially expressed proteins play a role in the pathogenesis of BA, which provides potential target information for the treatment of BA.
