Background: Obesity, especially central obesity, is a risk factor for non-communicable chronic diseases such as dyslipidemia, type 2 diabetes mellitus (T2DM), cardiovascular diseases (CVD), and metabolic syndrome (MetS). Aim: Study the association between the subcutaneous fat area (SFA) and visceral fat area (VFA) with lipid metabolism parameters in adults with MetS. Materials and Methods: Data from 1511 participants who visited the ‘NURA Mongolia’ Ai Health screening center between September 2023 and February 2024, including general information, DEXA (Dual X-ray Absorptiometry), and biochemical analysis results, were used. Metabolic syndrome (MeS) was assessed based on the harmonizing criteria 2009 (≥3 criteria). VFA and SFA were categorized into four groups using quartiles (Q1-Q4). Statistical analysis was performed using SPSS v26, including T-tests, multiple logistic regression (OR, 95% CI), and ROC (AUC) analysis. Results: The average age of the participants was 30.5±3.9 years, with a BMI of 25.1 kg/m², and 49.5% were male. The group with MetS (n=531) had significantly higher levels of VFA and SFA compared to the group that rated their health as relatively healthy and had no clinical diagnosis (n=979) (control group) (p<0.0001), with males showing higher VFA and females showing higher SFA (p<0.0001). The Q4 group for VFA had a significant association with MetS in males (4.611, 95% CI=2.394–9.591) and females (2.253, 95% CI=1.097-3.912) (p<0.001). Logistic regression analysis showed that increased VFA was more strongly associated with MetS in males (β=0.325, p<0.0001) and females (β=0.338, p<0.003) than BMI. The AUC for predicting MetS was 0.790 (95% CI=0.750-0.831) for VFA and 0.401 (95% CI=0.351-0.451) for SFA, with all results being statistically significant (p<0.001). VFA had a higher predictive value compared to other markers. Conclusion In healthy men with metabolic syndrome, VFA is more prominently defined, while SFA is higher in healthy women. Since VFA is a better predictor of metabolic syndrome than SFA, it increases the risk of diseases such as cardiovascular diseases and type 2 diabetes in men, whereas SFA in women serves as a protective factor.

Background: In 2022, the World Health Organization (WHO) reported that globally, 2.5 billion (43%) of adults aged 18 and older were overweight, with 890 million (16%) of these individuals classified as living with obesity. Some genes such as the FTO gene are strongly associated with obesity and overweigh. The FTO protein is crucial in regulating food consumption, appetite, energy equilibrium, and expenditure. Aim: The identify single nucleotide polymorphisms rs9939609 and rs17817449 of the FTO gene, which are associated with obesity, and to study their correlation with antropometric measurements and some laboratory test parameters. Materials and Methods: According to the inclusion and exclusion criteria, 50 obese (BMI >30 kg/m²) were included in the case group, and 50 relatively healthy and normal weight (BMI 18.5-24.9 kg/m²) were enrolled in the control group, for a total of 100 people matched for age and gender (1:1). We took physical measurements and collected peripheral blood samples after obtaining informed consent from each participant. Laboratory analyses assessed some parameters of lipid and glucose metabolism. We used the PCR-RFLP technique on two genotype SNPs. A p-value below 0.05 was considered a statistically significant result. Results: In this study, including 100 people aged 23 to 75, the mean age was 46.81±11.54 years, with 60% being female. In terms of antropometric measurements, body mass index, waist circumference, and arterial pressure were markedly elevated in the case group compared to the control group (p<0.001). In laboratory measures, fasting blood glucose, cholesterol, and mean LDL mean levels were statistically significantly higher in the case group compared to the control group. On the other hand, HDL cholesterol levels were lower in the case group compared to the control group. The FTO gene rs9939609 single nucleotide polymorphism was identified in 62% of the total study individuals as TT, 35% as AT, and 3% as AA genotypes. Also, FTO gene rs17817449 single nucleotide polymorphism was identified in 62% of the total study individuals as TT, 33% as AT, and 5% as AA genotypes. Conclusion The rs9939609 AT/AA genotype of the FTO gene elevates the risk of obesity and is associated with increased body weight, waist circumference, and BMI.

Introduction: Since 1993, the Inula helenium L. plant has been planted in the production area (Bulgan Province, Dashinchilen Sum) of the Traditional Hatchery Science and Production Corporation’s medicinal plant introduction and cultivation experience. At the Drug Research Institute, there is also a botanical institute for medicinal plants where it is grown. In traditional Mongolian medicine, the roots and rhizomes of Inula helenium L. are used to reduce inflammation, boost immunity, enhance hunger, and improve intestinal motility. Inula helenium L. roots and rhizomes contain biologically active compounds such as monoterpenes, sesquiterpenes, phenols, flavonoids, and polysaccharides. Methods: The roots and rhizomes of Inula helenium L. were extracted with water and 70% ethanol at the following ratios 1:10 (2% of WAC), 1:8, and 1:6 by partial maceration at 700C for 2 hours each, extracted and concentrated. The dry extract was obtained by the spray drying procedure. High-performance liquid chromatography for determining the content of alantolactone, thin-layer chromatography for qualitative analysis. Spectrophotometer for determining the content of polyphenolic compounds, colored compounds with Folin-Ciocalteu reagent for qualitative analysis. Spectrophotometer for determining the content of inulin, and colored compounds with phenol and sulfuric acid solutions for qualitative analysis. Conclusion In determining the content of polyphenolic compounds, inulin, and alantolactone in the dry extract taken from the roots and rhizomes of cultivated Inula helenium L., the content of polyphenolic compound in dry extract A was 2.50±0.08%, and alantolactone was 1.39±0.11% in the raw material of the plant, while B dry the extract had a high concentration of inulin of 58.51±0.66%.

Introduction: The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) has increased significantly over the last three decades worldwide, from 17.6% in 1990 to 23.4% in 2019. The development of this disease depends on many risk factors, including genetics, lifestyle, and environment. The PNPLA3 (patatin-like phospholipase domain-containing protein 3) gene is the most relevant genetic factor influencing the risk of metabolic dysfunction-associated steatotic liver disease. The PNPLA3 rs738409 GG genotype impairs adiponutrin function, accumulating triglyceride in liver cells and forming small fat droplets within the liver. Aim: To determine rs738409 and rs2896019 single nucleotide polymorphisms of the PNPLA3 gene in metabolic dysfunction-associated steatotic liver disease and their correlation with some parameters of anthropometric and laboratory tests. Materials and Methods: This study was conducted with a case-control design in 2023–2024. There were 150 participants in the study, 50 in the control group without MASLD, and 100 in the case group with MASLD. The PNPLA3 (rs738409, rs2896019) gene’s single nucleotide polymorphism was identified by the RFLP-PCR technique. All statistical analysis was performed using SPSS 23 software. Categorical variables were described by numbers and percentages, and the numerical variables were characterized by the median (min and max) for the normal distribution, and mean± standard deviation for the non-normal distribution. The statistical tests utilized were the Chi-square test, Fisher’s exact test, student t-test, and Mann–Whitney test. Ethical approval for the survey was obtained from the Medical Ethics Committee under the Ministry of Health Of Mongolia in January 2023. Results: The participants’ average age was 46.73±11.45, with 60% being women (90) and 40% being men (60). Among all patients, the PNPLA3 gene’s single nucleotide polymorphism rs738409 revealed 44.7% (67) CC, 54.7% (82) GC, and 0.7% (1) GG (OR-CG+GG genotype- 2.9, p=0.003). In addition, as a result of determining the PNPLA3 gene rs2896019 single nucleotide polymorphism, the frequency of the TT genotype was significantly higher in the control group than in the case group (48%, 31%, p = 0.042). Conclusion The frequency of CG/GG genotypes rs738409, and rs2896019 of the PNPLA3 gene is higher in the case group, suggesting that they may be more susceptible to MASLD.

Background: To prevent and combat the spread of the COVID-19 pandemic, the Government of Mongolia has implemented measures such as movement and time restrictions, social distancing and isolation, closure of schools, kindergartens and public places, immunization, and others. It has caused adverse consequences for people, social relations, and the economy, causing health, social, economic, and humanitarian crises. Not only does this situation, medical students, as frontline healthcare workers, are more susceptible to virus infection. Vaccines against COVID-19 have been researched quickly due to the pandemic and are being used under emergency use authorization. In our country the approach of mixing vaccine doses from different manufacturers was used (fractional doses). Therefore, there is no study on the exposure of medical students to the COVID-19 infection and the adverse effects after receiving a dose of a heterologous vaccine. Objective: To study the exposure to the COVID-19 infection and vaccination status of medical students. Methods: The survey was conducted from November 2023 to December 2023 using a cross-sectional study design, and 170 students who study at ASUSU and live in the dormitory were included. Results: A total of 170 students participated in the study. 55.9% (n=95) of them were in the first year, 22.4% (n=38) were in the second year, 10% (n=17) were in the third year, 7.6% (n=13) were in the fourth year, 2.4% (n=4) were from the 5th year and 1.8% (n=3) were from the 6th year students. 88.2% (n=150) of students were female and 11.8% (n=20) were male. In this study, 37.1% of the students were infected by COVID-19 infection previously. Among them, 50% of the students were infected from family members, 16.7% from the school environment, and 15.2% did not know about the source of infection. 76.2% of the respondents were diagnosed with COVID-19 in a medical institution, and forty-one students answered that they were treated at the hospital. 83% of the cases were treated at home and were cured within 14 days. In contrast, 93.8% of the hospitalized students were treated within four months to 1 year. The current study demonstrates neurological, respiratory, sensory, cardiovascular, psychiatric, digestive, and dermatological symptoms were in 37.6%, 24.1%, 27.6%, 17.6%, 11.8%, 11.2%, and 10% of the students who participated in the study, respectively. For a year or more, symptoms of all organ systems were present, but neurological symptoms appeared to be the highest. 55.9% (n=115) of the enrolled students received 3 or 4 doses of the vaccine, 3.5% (n=6) did not receive the vaccine. In total, 35% (n=60) of the enrolled students experienced side effects and 65% (n=106) had no side effects. Conclusion In this study, 37.1% of the students were infected by COVID-19 infection previously. According to the current study, symptoms related to the nervous system was the most prevalent and 55.9% (n=115) of the enrolled students received 3 or 4 doses of the vaccine. In total, 35% (n=60) of the enrolled students experienced side effects.

Abstract: Burn injury causes considerable incidence of disability, increase of hospitalization and rehabilitation. It is a crucial factor of morbidity and mortality, throughout the world, especially in the developing countries. Burn wound healing is a complex process including inflammation, granulation, and regeneration of the skin tissue. There are many animal and mineral derived agents applied for burn wounds treatment. For example, minerals and animal yellow marrow are applied as standard topical therapy in healing of burn wounds in the history. Specially, Mongolian camel’s (Camelus Bactrianus) yellow marrow and cinders have been used the healing effect standard topical antimicrobial for burn wounds for several centuries. The present study aimed to determine the healing effect of “CIBO” ointment with animal and mineral raw materials on third -degree burn wound in rats. Introduction: In our study, we selected an ointment containing a combination of yellow marrow and cinder. In ancient times, Mongolians used camel yellow marrow to relieve joint pain, spread people who had been bedridden for a long time due to the disease, and to prevent caries, and to use it on open wounds. In traditional medicine, cinder has been used as a mineral raw material and has been used to treat frostbite and burns. Material and methods: In the Vivar Department of the Pharmacology Sector of the Drug research institute, 18 Wistar white rats weighing 182-220 g fed in one environment for (12 hours a day/12 hour a night) were randomly selected and divided into the following groups. These are: negative control, Group 1 “Yellow marrow + Uvs black cinder”, Group 2 “Yellow marrow + Uvs brown red cinder”, Group 3 “Yellow marrow + Chinese red cinder”, Group 4 “Yellow marrow + Chinese white cinder”, Standard “Mebo” wound ointment. The wound area was prepared by scraping the hair 5 cm from the back of the test animal’s skull. The prepared area was sterilized with 70% ethanol and 10% iodine solution, resulting in a third-degree burn wound of 2.4 cm2. Wound experiential’s ointments were applied once daily for a total of 28 days, and wound healing was evaluated at 0, 3, 7, 14, 21, and 28 days after pathogenesis, with 16.1-pixel accuracy. Photo confirmed using a SONY brand camera. Result: “CIBO” ointment contains four deferent cinders which are from collected from deferent area and that have been shown to good affect burn wounds, and is more compatible with yellow marrow than Group 4 (Yellow marrow+Chinese white cinder).
Wound healing variables of control group compared with group 4 (Yellow marrow + Chinese white cinder) increased by 11.1% on the 3th day, 4% on the 7th day, 44.8% on the 14th day, and 54.5% on the 21st day. On the 28th day, healing and regeneration were accelerated by 50%. Conclusion The group 4 (Yellow marrow + Chinese white cinder) has been shown to have a pharmacological action of rapid healing and regeneration of burn wounds caused by experimental rats. It has also been shown to have pharmacological action to regenerate skin tissue and suppress inflammation caused by burns. Inclusion of Chinese white cinder in “CIBO” ointment promotes regeneration and healing of “CIBO” ointment.

Introduction: In Mongolia, there is opportunity to replace importing products by using raw materials based on the animal and minerals. Those products can be used for medical purposes.
In traditional medicine, yellow marrow has been widely used to treat burns and mechanical wounds, as well as frozen and open wounds. The purpose of this study was to determine the pharmacological action of “CIBO” ointment. We created a model of mechanical wound to evaluate the healing of wounds and its index after applying the ointment contains the above mentioned raw materials. Material and methods: Four different groups of “CIBO” ointment was prepared in the technology sector of the Drug Research Institute. Mebo wound ointment was used for comparison as control. The study was con- ducted in the Pharmacology Sector of the Drug Research Institute on white rats of the WISTAR breed under one feeding regime and one condition (12h / 12h). Mechanical wound injury and exposure to open wounds in experimental rats and its size were measured on the 3^rd, 7^th, 14^th, 21^st, and 28^th days of treatment. Wound healing, morphology, structure, size, and its index was quan- tified based on the defects. The ointment were applied once a day during the treatment period of 28 days to cover the wound. Result: Mechanical wound showed that study treatment group healed 0-6.2% on the 3^rd day, 21.4-35.7% on the 7^th day, 50-60% on the 14^th day, and 33.3-50% on the 21^st day separately compared with the untreated group. On the 28^th day, all the groups were decreased by 66.6%. The wound index was between from 0.002 to 0.0005 in the all experimental groups. Among experimented groups, the group consists of yellow marrow and Chinese white cinder was showed better performance than other groups. Conclusion The study group 4 (Yellow marrow + Chinese white cinder) has been showed to have a pharmacological action of rapid healing and regeneration of burn wounds caused by experimental rats. It has also been shown to have pharmacological action to regenerate skin tissue and suppress caused by mechanicals. Inclusion of Chinese white cinder in “CIBO” ointment promotes regener ation and healing of “CIBO” ointment.

Background: The incidence of gastric cancer has been declining worldwide in recent years; on the contrary, it has increased in the last decade in Mongolia. In Mongolia, over 80% of gastric cancer cases are diagnosed in the late stage. We performed a gastroduodenoscopy for screening and histological evaluation to diagnose gastric cancer. These methods are an effective diagnostic modality for gastric diseases; however, invasive and cause discomfort, making it an undesirable procedure for patients. Aims: To determine serum PGs and H.pylori IgG in atrophic gastritis and gastric cancer patients and evaluate the risk by ABC(D) classification. Materials and Methods: We selected 40 atrophic gastritis and 36 newly diagnosed gastric cancer patients from National Cancer Center of Mongolia, before surgery and other therapies. Besides, we enrolled population-based 38 healthy controls. Subjects of three groups were matched by age (±1) and sex. Written informed consents were obtained from all subjects. The fasting blood samples were collected and tested PGI, PGII, and H.Pylori IgG levels by enzyme-linked immunosorbent assay. Also, PGI to PGII ratio (PGI/II ratio) was calculated. We classified subjects into four groups based on ABC(D) classification. All statistical analyses were performed by SPSS (version 26.0, Chicago, IL, USA) software. Results: Median age of the subjects was 62, 52.6% (n=60) were male. Proportions of family history of gastric cancer and previous history of gastric disease were significantly higher in the gastric cancer group compared with atrophic gastritis and healthy control groups (p<0.05, p<0.05). H.pylori was positive in 67 (58.8%) subjects according to H.pylori IgG assay and there was no difference between study groups. The serum PGI level and was significantly decreased in gastric cancer and atrophic gastritis groups as compared to the healthy control (p<0.05, p<0.05). The PGI/II ratio was significantly lower in the gastric cancer group compared with the healthy control (p<0.01). The optimal cut off value of PGI was ≤35.25 ng/ml (AUC 64.3, 95% CI 51.3-77.2, p<0.05) for gastric cancer and PGI was ≤75.07 ng/ml (AUC 65.2, 95% CI 53.0-77.3, p<0.05) for atrophic gastritis. Also, the optimal cut off value of PGI/II ratio was ≤5.27 (AUC 71.6, 95% CI 69.6-82.8, p<0.01) for gastric cancer and PGI/II ratio was ≤6.25 (AUC 62.7, 95% CI 50.1-75.3, p<0.05) for atrophic gastritis. According to classification of atrophic gastritis patients and healthy control, group D had higher proportion of atrophic gastritis cases than group A, B and C (OR 5.04, 95% CI 1.13-22.50, p<0.05). According to classification of gastric cancer patients and healthy control, groups C had higher proportion of gastric cancer cases than group A, B and D (OR 6.19, 95% CI 1.04-36.78, p<0.05). Conclusion Our findings suggest that PGs level and H.pylori IgG may predict development of gastric cancer and could identifying individuals at high risk of gastric cancer and precancerous lesions who may need endoscopy.

Introduction: Cancer is a major public health issue both in Asia and in Mongolia. The most prevalent cancer related deaths in Mongolia are registered for the stomach, esophagus and liver. Purpose: We aimed to investigate the incidence of stomach and esophageal cancer in Mongolian population. Materials and Methods: Epidemiologic data were collected from 2009 to 2018 through the oncology cabinet of all hospitals and medical centers from all provinces, soums (the smallest unit of provinces) and major districts of the capital city. The incidence of stomach and esophageal cancer was calculated by appropriate methods and it was presented by ArcGIS Pro 9.2 software. A P-value of less than 0.05 was considered to be statistically significant and based on two side hypotheses. All calculations were performed in the IBM SPSS Statistics software. The study design in concordance with ethical guidelines was approved by the Ethics Committee of Ministry of Health Mongolia. All clinical investigations were conducted according to the principles laid down in the Declaration of Helsinki. Results: The incidence of esophageal cancer in last ten years (2009-2018) was 10.09 in 100000 populations and the highest incidence were registered in Uvs (38.13), Bayan-Ulgii (24.15) and Zavkhan (18.18) provinces, respectively. The incidence of stomach cancer was 20.33 in 100000 populations and the highest incidences were registered in Uvs (53.01), Khovd (46.02) and Darkhan-Uul (40.50) provinces, respectively. Conclusion
1. Incidence rates for esophageal and stomach cancer are high among the Mongolian population. In the last decade, the incidence of esophageal cancer had not decreased significantly, but it’s constant.
In our study, the esophageal cancer incidence was 10.09 per 100’000 people, which includes one of the high incidence rate countries according to the WHO classification. More than 10 aimags incidence rate of esophageal cancer was higher than the National average. Most of them have occurred in the western region of the country. Most of the Western, some of Khangai and Eastern soums have had the highest incidence of esophageal cancer what we have shown on the mapping.
2. The incidence rates of stomach cancer were registered as 20.33 per 100’000 people in the last 10 years at the national level. It has shown that according to the WHO classification, our country is also one of the countries with the highest incidence of stomach cancer. The stomach cancer incidence trend was increased in the last 10 decades. Therefore, some of aimag’s soums has included the highest rate classification. In addition, some soums in the Western, Khangai, and Eastern aimags had have a very high incidence of stomach cancer.
According to results in the above, the nationwide targeted prevention program is needed especially where the highest incidence rates. Also there is a lack of cooperation between national organizations to accurate registration of gastrointestinal cancer and to fight against these harmful cancers.

Introduction: In 2018, a total of 901 new cases of gastric cancer were recorded, of which 64.8% in males and 34.2% in females. The incidence rate of gastric cancer was 28.5 per 100 000 population, which 38.2 for males and 19.2 for females. Goal: We aimed to investigate the associations between some risk factors and gastric cancer among the Mongolian population. Materials and Methods: A case-control study was conducted between November 2017 and September 2019. We selected 120 cases from National cancer center of Mongolia who newly diagnosed gastric cancer. And 120 controls were selected by matching by sex, age and the place of residence. Informed consents were obtained from all subjects. All subjects were personally interviewed with researchers used by a structured questionnaire consisting of 86 questions. The SPSS 21 (version 16.0, SPSS Inc., Chicago, IL, USA) software was used for all analyses. Results: The mean age was 59.2±11.4 (26-85) years. Habits of having dinner after 6.00 pm (OR 1.42, 95%CI 1.11-1.83, p=0.008), having leftover meals (OR 2.22, 95%CI 1.27-3.86, p=0.008), daily consumption of tea with salt (OR 1.97, 95%CI 1.18-3.30, p=0.01), smoking on an empty stomach (OR 2.44, 95%CI 1.11-5.37, p=0.033), weekly consumption of ham and smoked meat (OR 1.5, 95%CI 1.17- 2.13, p=0.02), and consumption of fat grease (OR 2.09, 95%CI .03-4.24, p=0.038) were significantly increased gastric cancer risk. In contrast, habit of eating at regular times (OR 0.43, 95%CI 0.25-0.73, p=0.002), chewing thoroughly (OR 0.39, 95%CI 0.23-0.67, p=0.001), cooking meat thoroughly until it’s tender (OR 0.48, 95%CI 0.25-0.97, p=0.047), daily consumption of vegetables (OR 0.45, 95%CI 0.27-0.76, p=0.003), and daily consumption of fruit juice (OR 0.36, 95%CI 0.15-0.85, p=0.026) were significantly reduced gastric cancer risk. Furthermore, having first-degree relatives diagnosed with gastric cancer had 2-3 fold higher increased risk of gastric cancer (parents OR 2.88, 95%CI 1.07- 7.78, p=0.038, sibling (OR 3.09, 95%CI 1.09-8.81, p=0.036). Also, previous records of the digestive disease increased risk of gastric cancer (OR 3.65, 95%CI 2.10-6.35, p<0.0001). Conclusion Dietary habits, family history of gastric cancer and previous records of digestive disease were associated with risk of gastric cancer. Thus, prevention effort could be focused on the population with a family history of gastric cancer, changing bad dietary habit and screening precancerous disease of gastric cancer.
