Ilioinguinal (II) and iliohypogastric (IH) nerve blocks are often performed to provide intra- andpostoperative analgesia for hernia repair in children and adults. Several techniques are describedin the literature. Recently an ultrasound guided technique for II and IH nerve blocks were describedin the international journals. The block success rates are variable specially for using anatomicallandmark blind techniques. In the present study, the anatomical variations in course of the II andIH nerves are described. Knowledge of the course of these nerves in the inguinal region, and anunderstanding of variations seen in their topography, can decrease the incidence of postoperativecomplications and adverse effects. Ultrasound guidance of block performance will shorten the time,reduce the number of needle passes and shorten the block onset time. Blocks may be performedusing lower local anesthetic doses.

Background: The aging of the world’s population will determine global health trends. According to the 2021 report of the Capital City Health Department, the average life expectancy of the Mongolian population is 71.3 years (male 67.3, female 76.7), the difference between male and female life expectancy is 9.4 years, and elderly people aged 60 and over account for 8.1% of the total population. The report also shows that 6.5% of all outpatient visits are for people aged 60-64, and 9% are for people aged 65 and over, which means that they do not receive adequate health care services. Therefore, it is im portant to increase the access to and quality of health care services provided to the elderly in order to improve their health and quality of life. Comorbidities that are common among the elderly are one of the pressing issues in the health sector. Aim: We aimed to study the prevalence and risk factors of multi-morbidities among older adults (aged sixty years and over) in urban and rural areas. Materials and Methods: To accomplish our aim, we conducted 156 lifestyle related questionnaires and 18 health related questionnaires among 720 older people in Ulaanbaatar city and rural areas, and created the database. Pearson correlation coefficient was used to determine the relationship between the quantitative influence of factors using single and multi-fac tor linear (β-coefficient) and binary logistic regression (odds ratio, CI 95%) methods, and p value less than 0.05 was con sidered statistically significant. The Apriori algorithm in SPSS was used to determine the relationship between multiple chronic diseases in the elderly people. Results: The prevalence of comorbidity was higher in urban areas (48.1%) and rural areas (51.9%), and ageing (urban areas OR: 2.45, 95% CI: 0.9-6.2; rural areas OR: 6.35, 95% CI: 1.47-27.4, P<0.01) was a risk factor of multi-morbidi ties. Multimorbidity is defined as the presence of 2 or more chronic conditions, and 3, 4, and 5 chronic conditions were co-occurred to older adults with chronic conditions, 28.7% (165). 11 common patterns of relationships in urban areas and 18 common patterns of relationships in rural areas (support (A→B)>3%, confidence (A→B)>30%, lift (A→B)>1) were determined. Conclusion Multimorbidity was different in urban and rural areas, 11 common patterns in urban areas and 18 common patterns in rural areas were determined. It has shown that the prevalence of multimorbidity was different in urban and rural areas.

Background: Development and progression of cancer is accompanied by different morphological and functional changes of cells. One of the most important changes is the expression and activity of enzymes in the cellular fatty acids metabolism that reflects in cell membrane lipid composition and increases fluidity of cancer cell membrane. The Ellipin, prepared from bovine liver, is a newly developed anticancer agent containing several important fatty acids.Goal: To investigate effects of Ellipin on hepatic cancer cell function such as proliferation, migration and adherent activity and apoptosis of cancer cell lines in vitro.Materials and Methods: This study was conducted in the Laboratory of Molecular Biology, Institute of Biology, MAS. The Ellipin was developed in the Drug Research Institute of Monos group. HepG2, HCC, 23132/87, MDCK cells lines and the primary liver cancer cells (PCC) were used for proliferation assay. Only HepG2 cell line was used for MTT, Migration, Spreading and Apoptosis assays.Results: The results of proliferation assay showed that the ellipin decreased the proliferation activity of HepG2 and PCC cells depending on concentrations; in 50μg/ml 2-3 times, 250μg/ml fully stopped cells divisions. The Ellipin reduced mitochondrial reeducates enzyme activity of HepG2 cells depending on its concentrations. For example, in 50μg/ml ellipin concentration case, the number of alive cells decreased 2 times. The migration of HepG2 cells treated with 100μg/ml ellipin was decreased by 22.3% compared to the control cells. Also the number of adhered cells was reduced by Ellipin treatment. After 50μg/ml, 100μg/ml, 250μg/ml ellipin treatment, the number of apoptic cells were 14,6%, 45,6%, 100% of initial culture cells, respectively.Conclusions: Our results showed that the Ellipin suppresses HepG2 cancer cell proliferation and decreases migration and spreading activities and also inducts the cell apoptosis.

Postoperative pain score was higher in control group and the first analgesic requirement time was 2h. In the study group had mild to moderate pain and the the firstanalgesic requirement time was 4h.Transversus abdomines plane block under ultrasound guidance was easy, safe, reliable and effective analgesic in children undergoing open appendectomy surgery.

BACKGROUND. Regular blood donation can lead to pre-clinical iron deficiency as well as iron deficiency anemia. With Each donation donors lose 220-250 mg of iron. Early detection of iron deficiency is important for the blood donors and even useful for blood and blood product safety and supply. The research work we studied present Ret-HE to be used to detect the occurrence of iron deficiency eritrony level. Purpose: The aim of this study was to determine Ret-He to have sensitivity and specificity for diagnosing iron deficiency than traditional iron measurements. Materials and methods: We performed a cross sectional and case control study of 156 blood donors who served National Center for Transfusion Medicine. Ret-He, hemoglobin, plasma iron and ferritin were measured using XN2000 Sysmex, and CobasE600 Roche. The statistical analysis was done using One way Anova, Rock curve, Kruskal Wallis test. Results: We examined 64(41.02%) male donors, 92(58.9%) female donors by measurements of Ret-He,hemoglobin, serum, iron and ferritin. Survey participants were 8.33%(n=13) with anemia, 91.67% (n=143) without anemia. In donors with anemia the results were: RBC 4.9*106 u/l, HGB 10.8 g/dl (10;11), serum ferritin 5.2 (4.3; 6.3) mmol, serum iron 4.5 (3.7; 5.8) mmol and Ret-He 25.5 (22; 26) pg. Donors were divided into 3 age groups: group I age was up to 25years, group II was between 26-35 years, group III age criteria was above 35. Group I had serum iron 13.5 (10.; 18.), serum ferritin 41.8 (14; 78), Ret-He 32.2 (30; 33.) RBC 5×106 u/l (4.6;5), HGB14.2g/dl (13.3;14. 2). Group II had serum iron 14.6 (11; 19), serum ferritin 54.1 μg/l (29; 138), Ret-He 32.2pg (31; 33), RBC 5.1×106 u/l(4.7;5.1), HGB14.8 g/dl (13.5;14.8),Group III had serum iron 15.1 umol/l (9; 20), serum ferritin 95.7 μg/l (39; 141), Ret-He 32.7pg (31; 34) , RBC4.9×106 u/l(4.6;4.9), HGB 14.5g/dl(13.8;14.5), respectively. According to a curve (Roc) analysis, AUC of serum iron was 0.0963, serum ferritin 0.909, Ret-He 0.975. The mean Ret-He was 32.3pg (31.3;33.4). The optimal cut off value for the Ret-He was 29,25pg by ROC analysis and are presented along with sensitivity 92.3% and specificity 95.1%. Conclusion: 1. Determining the amount of Ret-He has a better sensitivity and specificity for diagnosing iron deficiency compared to traditional iron measurements. 2. Ret-He has diagnostic indicators that are able to detect the depletion of iron reserves, erythron level. And it need to be used in further clinical practices, as well as doctors should be required to use it for diagnosis and treatment.

Introduction: Base excision repair (BER) is mainly responsible for the correction of small base changes of DNA damage. BER pathway involved many enzymes including OGG1 and XRCC1. The defective DNA repair is associated with an increased risk of various cancers including hematologic malignancies-leukemia and myelodysplastic syndrome (MDS). However, it is deniably these polymorphisms alter the susceptibility and clinical outcome of MDS patients. The aim: This study was to evaluate the impact of polymorphisms in gene encoding one protein of BER system: XRCC1 Arg399Gln in MDS and healthy population. Methods: In this study, we recruited 60 health control group [median 47.9 years, 9 MDS subjects [median 56.6 years] were included in this study. Genotyping was carried out by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. Allele and genotype frequencies were calculated by direct counting. Result: The frequencies of genotypes of XRCC1 Arg399Gln were as follows: Arg /Arg 1 (11%), Arg/Gln 6 (66%), Gln/Gln 2 (22%) in MDS and Arg /Arg 18.4%, Arg/Gln40%, Gln/Gln41.6% in health control for XRCC1 Arg399Gln. The result revealed that genotypes Arg399Gln increased the risk of MDS In conclusion this study is the first to analyze XRCC1 SNPs and their associated risk of MDS in Mongolian samples. To fully understand the role of DNA damage and DNA repair in the MDS, prospective studies are needed and other genes (OGG1 Ser326Cys, MUTYH Gln324His, APE Asp148Glu) of base excision repair pathway should be analyzed.

BACKGROUND. Previous retrospective study from our team showed that RDW significantly increased in chronic heart failure (CHF). OBJECTIVE. The aim of the study was to compare the value of RDW-CV with NT-pro BNP and evaluate sensitivity and specificity of RDW for diagnose of heart failure. MATEREALS AND METHOD. Here, we analyzed 20 patients who were suffering from heart failure and were treated in the department of Cardiology, First Clinical Hospital between in June 2017. All patients in the study group were underwent a complete blood count, immunoassay for NT-proBNP. The ejection fraction was analyzed by ECHO cardiograpy. RESULTS. 85.0% of patients were male and remained was female. RBC and RDW was significantly differentially measured in between CHF groups (р= 0.028 p=0.0001). In control groups without heart failure NT-proBNP was estimated up to 100 pg/ml, whereas it was definitelly increased in patient with CHF (р=0.0001). There was strong correlation between RDW and NT-proBNP (r =0.846, p=0.0001). sensitivity and specificity of RDW was 89%, and 74.3 % respectively in CHF. CONCLUSION. According to the our results there was direct correlation between RDW-CV and heart failure (p=0.035). RDW-CV migh be cost effective and routine laboratoty marker to evaulate CHF.
