ABSTRACT
Introduction@#Air pollution has become one of the major problems in socio-economic and health issues in Mongolia. Among the various hazards of particulate matter (PM) pollutants, microorganisms in PM2.5 and PM10 are thought to be responsible for various allergies and for the spread of respiratory diseases. Recent studies have shown that PM2.5 particles can cause chronic heart failure, heart arrhythmias, and strokes, as well as lung damage, cirrhosis, inflammation, cancer, cardiovascular disease, and metabolic disorders. Furthermore, some studies have concluded that PM2.5 particles in the environment are a risk factor for gastrointestinal, liver, colon, and lung cancer as well as it affects the growth and metastasis of various cancer cells caused by other factors. In our country, the health effects of air pollution and the relationship between the pathogenesis of cancer research are scarce. Therefore, the study of the effects of PM2.5 particles on cancer cell proliferation, migration (metastasis) can provide a significant role for cancer treatment, diagnosis, and prevention.@*Purpose@#Determining the effects of PM2.5 particles on cancer cell proliferation, migration (metastasis) in in-vitro@*Material and Methods@#A human liver cancer cell line (HepG2), human gastric cancer cell line (AGS) were obtained from the central scientific research laboratory in the Institute of medical sciences. HepG2, AGS cells were seeded at a concentration of 1*105 cells/mL in a culture flask and cultured in RPMI-1640 medium supplemented with 10% FBS, 1% antibiotic mix (penicillin, streptomycin) in a humidified atmosphere of 5% CO2 at 37 °C. The cytotoxic effect of PM 2.5 in AGS, HepG2 cells were evaluated by MTT, CCK8 assays. AGS, HepG2 cells were incubated in 96 well plates for 24h then treated with different concentrations (0, 5, 10, 25, 50 and 100 μg ) of Bayankhoshuu, Buhiin urguu, and Zaisan samples for 24h, respectively.@*Results@#Concentrations of 10, 25, and 50 μg/ml of samples collected from the Bukhiin urguu and Zaisan in March increased HepG2 cell growth, while doses of 25, 50 μg/ml of samples collected from Bayankhoshuu in March and December increased HepG2 cell growth. Therefore, concentrations of 25 and 50 μg/ml of samples collected from Bayankhoshuu in March increased AGS cell growth, while concentrations of 25, 100 and μg/ml of samples collected in December increased AGS cell growth. However, no cytotoxic effect was observed in the sample collected from Zaisan in March, whereas the PM2.5 sample enhanced AGS cell growth in dose dependent manner in December.(p <0.05) @*Conclusion@#High levels of heavy metals were detected in samples collected in December from Bayankhoshuu, Bukhiin urguu and Zaisan of Ulaanbaatar. Concentration of 25 μg/ml of samples collected from the Bukhiin urguu and Zaisan in March increased HepG2 cell growth. Concentrations of 25 μg/ml of PM2.5 collected from three regions around Ulaanbaatar increased HepG2 and AGS cell migration.
ABSTRACT
Background and Aims@#Hepatocellular carcinoma (HCC) is a common cause of cancer related death in Mongolia. Early diagnosis is the very important management to increase successful treatment and survival rate. Glypican-3 (GPC3) protein is highly expressed in hepatocellular carcinoma (HCC) tissue and in serum of HCC patients. Recent studies have been conducted and suggested as a diagnostic biomarker for detecting HCC in the early stage. Therefore, we investigated the diagnostic value of the serum GPC3 level and compared it to the alpha-fetoprotein (AFP) level as a diagnostic biomarker of HCC.@*Methods@#We enrolled a total of 90 participants and divided into 3 groups with HCC (30), with liver cirrhosis (LC/30) and healthy (30) as the control group (30). GPC3 and AFP serum (sGPC-3, sAFP) levels were measured using commercially available enzyme-linked immunosorbent assay kits. The diagnostic accuracy was analyzed using the receiver operating characteristics (ROC) curve and estimated sensitivity and specificity of each biomarker. @*Results@#sGPC3 was significantly elevated in the HCC group as compared to liver cirrhosis and healthy subjects (658±138.2 pg/ml, 378±25.5 pg/ml, 356.3±29 pg/ml) respectively. sGPC-3 sensitivity was 96.6% and specificity was 100%. The area under the ROC curve (AUC) for GPC3 was 0.999 (0.996- 1.0).</br> In comparison, the mean of AFP was significantly higher in HCC (16.9±11.7 ng/ml) than in LC (6.7±7.6 ng/ml) and in healthy subject (3.3±2.1 ng/ml) and AFP sensitivity was 43,3 %, specificity was 95 % with an AUC of 0.808 (0.696- 0.921). </br> The combination of GPC-3 with AFP achieved the highest sensitivity (97.1%) and specificity (97%).@*Conclusion@#Serum GPC3 has a higher sensitivity than AFP for the early diagnosis of HCC. Combination of two markers showed greatest diagnostic accuracy.
ABSTRACT
@#Research of function of vitamin D on immune system has been studying since the study revealed that vitamin D receptor is expressed on the surface of the immune cells. 1,2-dihydroxyvitamin D3 [1,25(OH)2D], physiologically active form, can be generated through hydroxylation of 25-hydroxyvitamin D3 [25(OH)D], inactive form of vitamin D, in a liver, connecting with specific VDR make biological action. Vitamin D make different biological actions depends on connecting with different immunological cells. Some studies indicated that Vitamin D plays pivotal role in antibacterial innate immune responses through regulating reaction of the main cells as macrophages and dendritic cells. Moreover, calcitriol, the active form of vitamin D, is connected with VDRE, modulates the innate immune response through directly inducing expression of catelicithin and β-defensin as antimicrobial peptides, reducing secretion of IL-1b, IL-6, TNF-a, RANKL, COX-2 as proinflammatory cytokines and increasing production of IL-10, an anti-inflammatory cytokine. Vitamin D plays in proliferation and differentiation of T and B cells and regulates the activities of over 500 genes. Vitamin D differently impacts on per se stages of T cells’ proliferation. Vitamin D indirectly mitigates the differentiation from immature B cells to plasma B cells while it directly impacts on regulation of overloaded production of antibodies in plasma B cells. In conclusion, vitamin D modulates the innate- and adaptive immune response through regulation on activation of APCells, proliferation and differentiation of immune cells, secretion of some antibacterial peptides.
ABSTRACT
@#BACKGROUND. Annular elastolytic giant cell granuloma (AEGCG) is a rare skin disease, characterized by loss of elastic tissue due to elastophagocytosis by multinucleated giant cells in the upper part of dermis, which clinically presents as multiple annular plaques with raised erythematous border and central atrophy. We report a first case of AEGCG in dermatology practice in Mongolia. Its clinical and histological features, differential diagnosis and treatment modalities are described and discussed in detail.
ABSTRACT
@#BACKGROUND. Hemophilia B is X-linked recessive genetic disorder, caused by missing or defective factor IX that results in bleeding longer after an injury or surgery, easy bruising, and an increased risk of bleeding inside joints or the brain. The disorder affects approximately one in 30 000 males worldwide and 18 cases were registered in Mongolia according to statistics of Hemophillia Federation of Mongolia. The annual cost of episodic treatment of an adult with severe hemophilia estimated at ≈53000 USD owing to high cost of treatment developing countries has been adopted to prevent and to forecast the risk of inhibitor. Materials and Methods: The objective of this research is to determine F9 mutations in patients with Hemophillia B in Mongolian population and to assess correlation between genotype and phenotype of disease. Characterization of mutations was performed by direct sequencing of genomic DNA using a Sanger sequencing method. Briefly, the exon or part of the exon deletion was checked and amplified by polymerase chain reaction (PCR). Results: We identified four point mutations and one deletion. No large exon deletion was found in PCR amplification result. As expected, the most common mutations responsible for the disease were point mutations. In general, this study revealed 5 different mutations in unrelated 7 proband and there is good correlation between the type of mutation (location in the amino acid position and domain in the protein) and their functional outcome, yielding a predictable clinical severity.
