Background: The purpose of this study is to evaluate serum creatinine as a marker of estimated glomerular filtration rate (eGFR) in alcohol use disorder people, and to determine correlation between mean arterial pressure (MAP) and eGFR in chronic kidney disease classification level. Methods: In this study, 118 people were examined 2024. We measured serum creatinine based GFR using the Cockroft Gault formula. Biochemical analysis and serum creatinine were evaluated using a fully automatic analyzer (GOLSITE, China). Statistical results were analyzed SPSS. Result: The mean subject age was 48.6±10.3, BMI 25.3±3.7 and male: female ratio was 5:1. Mean arterial pressure was 104±12.8 mmHg, eGFR 94±28 ml/ min/1.73m2, and mean arterial pressure was significantly correlated with estimated glomerular filtration rate (P<0.05) and no difference between male and female recipients. Mean eGFR was calculated into 4 groups of 10-year intervals, that eGFR was decreased significantly with age groups. For the alcohol dependence stages of the Michigan Test, the mean eGFR was stage 1 is 112 ml/min/1.73m2, stage 2 is 89 ml/min/1.73m2, stage 3 is 97 ml/min/1.73m2 and there is not statistically significant correlation between Michigan test scores and eGFR. Conclusion According to our research, one of the optimal methods for assessing kidney function is the creatinine-based CKD calculation method, and long-term excessive alcohol consumption is a risk factor for CKD, as well as one of the main causes of death due to hypertension and cardiovascular disease.

Background: To evaluate changes in liver function in patients with alcohol use disorder and propose preventive measures. Methods: In this study, 118 people were examined between January 2024 to December 2024. Results were analyzed SPSS. Result: The mean subject age was 48.6± 10.3 years, male: female ratio was 5:1. Mean arterial pressure was 104±12.8 mmHg, ALT 86.7 ± 93.8 (U/L), AST 89.3±82.8 (U/L), GGT 213.8±252.3 (U/L). A statistically significant correlation was found between AST and ALT levels (R² = 0.562). However, no significant correlation was observed between body mass index (BMI) and blood glucose levels (R² = 0.002). The AST/ALT ratio was also statistically significant (p = 0.0001). Conclusion Excessive alcohol consumption increases the levels of liver enzymes AST 89.3 ± 82.8 (U/L), ALT 86.7 ± 93.8 (U/L), and GGT 213.8 ± 252.3 (U/L), leading to increased liver cell damage. Therefore, it is necessary to reduce alcohol consumption and implement preventive measures.

Background: Globally, gastric cancer accounts for 1,089,000 new cases and 769,000 deaths annually, ranking fifth in overall cancer incidence and third in cancer-related mortality. The aim to determine HER2 expression in patients with gastric cancer and to evaluate its correlation with clinical and immunological biomarkers, as well as the need for further laboratory diagnostics. Aim: To determine HER2 expression in patients with gastric cancer and to evaluate its association with clinical and immunological biomarkers, as well as the potential need for further laboratory diagnostics. Materials and Methods: A retrospective study was conducted using archived materials from patients with gastric cancer at the Clinical Pathology, Molecular Genetics, and Pathology Laboratories of the National Cancer Center of Mongolia, covering the period from 2019 to June 2025. HER2 protein expression in tumor tissue was assessed using immunohistochemistry (IHC), and chromogenic in situ hybridization (CISH-HER2) was employed to confirm gene amplification. Statistical analysis was performed using the Prisma-10 software. Results: In our study, among 210 cases of gastric cancer evaluated by IHC for HER2, 46 (21.9%) were HER2-positive and 164 (78.1%) were HER2-negative. When comparing patients with gastric cancer stratified into HER2 1+ (negative) and HER2 3+ (positive) groups, no statistically significant differences (p < 0.05) were observed in age, sex, tumor location (surgically resected tissue), morphology, or disease stage. However, a higher proportion of males was noted in the HER2 3+ group (80.9%), though this did not reach statistical significance (p = 0.0879). Significant associations were found with tumor markers. Elevated serum CA-72-4 (>5 ng/mL) was more frequent in the HER2 3+ group (58.8%; p = 0.0069). In contrast, elevated CA-19-9 (>35 U/mL) was more common in the HER2 1+ group (93.5%; p = 0.0117), and elevated CEA (>6.9 U/mL) was also predominant in the HER2 1+ group (90.6%; p = 0.002). These findings suggest that HER2 3+ status predominates in cases with elevated CA-72-4, which may influence diagnostic strategies and HER2-targeted therapies (e.g., trastuzumab). Conversely, elevated CA-19-9 and CEA were more associated with HER2 1+ status, indicating a need for further detailed investigation of these markers in relation to HER2 expression. In patients evaluated by CISH for HER2 expression, stratification into HER2-positive and HER2-negative groups revealed no statistically significant differences (p < 0.05) in age, sex, tumor location, morphology, stage, or serum tumor markers (CA-72-4, CA-19-9, CEA). This suggests that HER2 status (positive/negative) may be independent of these variables. Although HER2 positivity was higher in poorly differentiated tumors (48% vs. 30.6% negative; p=0.1414) and in stage IV disease (50% vs. 39.3% negative; p=0.2607), these differences were not statistically significant. Elevated serum markers (CA-72-4, CA-19-9, CEA) were observed but showed no significant correlation with HER2 status. Conclusion Determining the molecular profile of gastric cancer patients can significantly contribute to refining clinical diagnosis, developing treatment strategies, enhancing therapeutic outcomes, and improving patients’ quality of life.

Myocardial infarction (Ml) is necrosis and death of heart muscle secondary to ischemia and acute coronary artery thrombosis. Ml, commonly known as a heart attack, happens when the oxygen rich blood flow to a part of the heart muscle is blocked for a prolonged period, causing damage or death to the heart tissue. This blockage is most often caused by a buildup of fat, cholesterol, and other substances, which form a plaque in the coronary arteries. Furthermore, patients with cancer constitute a high-risk population for cardiovascular disease and as of the last 5 years, 50% of patients with cardiovascular disease have been diagnosed with cancer, according to World Health Organization. The provision of complete insight into Ml complications along with designing ajpreventive program against Ml seems necessary. The use of medications has been practiced over the years for the prevention of HF. However, some of these medications produce adverse effects and due to high cost are not easily available to every patient. Over the past decades, there has been a significant rise in the use of herbal supplements based on traditional medicine to prevent, avoid, and/or treat different conditions, including cardiovascular disease; this rise results from a natural source, efficiency with few or no adverse effects and low cost. In vivo models of heart failure (HF) and myocardial infarction (Ml) are essential for understanding the pathophysiology of these conditions and for developing new treatments.
These models typically involve inducing heart failure or myocardial infarction in animals, such as rodents to study disease mechanisms and evaluate potential therapies.
In this review, we discuss the most common preclinical models of Ml currently employed in cardiovascular research. Among them, Ml induced heart failure is a method of ligation of the left anterior descending artery of coronary an experimental animal. Its physiological relevance, cost-effective, uncomplicated, and suitable method for evaluating research results. The rat model of myocardial infarction offers numerous advantages that make it a valuable tool for cardiovascular research.

Background: USA implemented a national Biomonitoring program and as result found that 88% of the population is affected by secondhand smoking and then started a monitoring program to control smoking. In Mongolia, due to the capacity of the biomonitoring tests, only children’s lead level was determined. The study showed that blood lead level in children aged 0.5-14 years was 0.4-16.5 μg/dl in average. However, there is no reference level and therefore reference level from other countries are used. Objectives: To study the correlation between the environmental effect and toxic metal level in children’s’ blood Methods and materials: 103 children aged 0-5 years, consisting of 10 male and female children of each age. 6 kindergartens and 14 households were chosen for their internal air quality monitoring; measured the level of toxic metals and dust by cross-sectional study based on laboratory analysis. Results: 41.7% (44) are male and 58.3% (59) are female of the total participants. 16.5% (17) are 1 year old, 18.4 (19) are 2 years old, 23.3% (24) are 3 years old, 19.4% (20) are 4 years old, 22.3% (23) are 5 years old. The result showed the children’s’ blood level was 4.12±1.35 μg/dl. The lead level in the internal air of households close to steam boilers were measured and it was 0.000095 mg/m2. Conclusion 60.1% of the children had blood lead levels 3 times higher than the reference level. However, the lead level of internal air was lower than the reference level. No effect of Internal air quality on blood lead level was observed and weight and height were inversely correlated.

Introduction : Water is a vital resource for human existence and is essential for daily food processing, preparation, washing, hygiene, and sanitation. Furthermore, providing the population with safe drinking water is one of the pressing problems of the world and some regions.
In recent years, population density and the scale of commercial and industrial activities, as well as clean and dirty water consumption were increased in the capital city. As a result of these, ground and surface water resources are becoming scarce and polluted.
Therefore, assessment of daily drinking and residential water consumption of Ulaanbaatar should be determined to use drinking water properly in daily life and water loss. This study assessed the actual amount of households’ daily water consumption. Goal: The purpose of this study is to determine the daily consumption of drinking water for households in ger areas and apartments in Ulaanbaatar. Materials and Method: This study covers 30 households in ger areas and 15 apartment households, in Ulaanbaatar. Household members performed 6-10 types of measurements every day, within 7 days. As a result of these measurements, actual consumption of water quantity used for drinking and household purposes was calculated. Statistical analysis was done by SPSS Version 21 to calculate the true probability of difference between parameters. Result: 67.9% of the households in the ger areas were 4-5 family members. The average daily household consumption of drinking and domestic water were 68.3 ± 3.57 L (95% 61.3-75.3), the minimum consumption was 12 L, and the maximum was 227 L. Average of the household water consumption water was 97.6-108.9 liters during the weekends, and water consumption was statistically higher than weekdays (p=0.001; p=0.01).
The water consumption of residential households with 3 family members accounted for the majority (30.8%) in this study. The average daily consumption of drinking and domestic water was 297.67±19.7 liters. There was no statistically significant difference (p=0.96) in week. The average daily water consumption including drinking and residential was 270.3-335.97 L.
The total daily drinking and residential water consumption per person was 15.57 L for households in ger areas and 90 L for apartment households. Calculating the daily water consumption of households in ger areas, 60.3% of it is used for laundry, washing dishes, food preparation, washing face and hands, and clothes, 31% for drinking, and 8.7% for outdoor water use. While apartment households, approximately 94.1%, were used for household and 5.9% for drinking purposes. Research ethics approval : This study was discussed at the meeting of the Academic Council of the National Center for Public Health. In addition, this study was carried out according to the methods and methods discussed and approved at the meeting of the Medical Ethics Control Committee of the Ministry of Health (Resolution No. 08). Conclusion The total daily consumption of drinking and residential water per person were 15.57 litres for the households in the ger areas and 90 litres for the apartment households. It implies that it does not exceed the WHO recommendations

Introduction: Mongolia’s capital hosts about half the country’s total population, and its air pollution ranks among the highest in the world during winter. Air pollution is linked to reduced fetal growth, preterm birth, low birth weight, impaired cognitive intra-uterine development, impaired cognitive development, and even spontaneous abortion. Antenatal care includes fetal development monitoring, prevention of anemia, immunization against infectious diseases, prevention of sexually transmitted diseases, and any health risk factors such as environmental pollution.
Health care measures for pregnant women and children under one year of age have the potential to be highly effective because they are directly aimed at reducing pneumonia in children. As such, we need to conduct this survey to determine whether pregnant women were satisfied with the information and advice on air pollution prevention provided by health facilities and to take evidence-based measures. Materials and Methods : The survey data were collected using quantitative and qualitative research methods. In this study, a total of 958 pregnant women participated from Songinokhairkhan district, Bayanzurkh district, and Bayankhongor province center. The overall satisfaction of health services is calculated using the three dimensions namely: satisfaction with health service, operation, and environment of the Health Organization. Satisfaction scores were assessed using an even-point scale. These are “Very Dissatisfied-1 point”, “Dissatisfied-2 point”, “Satisfied-3 point”, “Very satisfied-4 point”. The results were calculated after entering the survey data into SPSS-23, creating a database, and performing error control. The research methodology was discussed at the meeting of the Academic Council of the National Center for Public Health on December 25, 2019, and the methodology was approved by the Medical Ethics Committee of the MOH (Stagnant №2). Results : The survey covered 958 pregnant women aged 16-45 in Bayanzurkh district Songinokhairkhan district, and Bayankhongor province. During antenatal care visits, the majority of pregnant women (BZD- 56.9%, SKHD- 68.3%, BKH province - 86.7%) were advised by their health specialists to go outside for fresh air, while women in Ulaanbaatar (BZD- 18.9%, SKHD- 24.7%) received the information and advice at the lowest percentage. Pregnant women in Ulaanbaatar were less involved in air pollution training than in Bayankhongor. Participants in the air pollution prevention training rated it as “satisfied” regardless of location. 37.2% of pregnant women obtained information on protecting their health from air pollution from the board of Family Health Center and 34% from their district health centers. 86.1% of the participants were able to obtain information on air pollution on their own, while 86% of them got information from their family and friends. Conclusion The percentage of pregnant women getting medical advice, training, and information on air pollution prevention from hospitals during their antenatal care visits was the highest in rural areas. Moreover, their level of satisfaction with counseling had been rated as “satisfied”. Pregnant women often seek information on air pollution prevention from non-professional sources, such as their family and friends.

Abstract Saposhnikovia divaricata, a perennial herb belonging to the family Umbelliferae, is widely distributed in many provinces of Mongolia. The dried root of Saposhnikovia divaricata has been used for the treatment of arthritis and as a painkiller in Mongolian folk medicine. Moreover, its dried root (Radix Saposhnikoviae) is used as a Chinese herbal medicine for the therapy of immune system, nervous system, and respiratory diseases. According to phytochemical and pharmacological studies, the main ingredients of Saposhnikovia divaricata are chromones, coumarins, acid esters, and polyacetylenes. These compounds indicate anti-inflammatory, antioxidant, analgesic, antiproliferative, and immunoregulatory activities. Cimifugin is an active ketone ingredient from Saposhnikovia divaricate, Rhizoma cimicifugae. Cimifugin has been reported to have bacteriostatic and antiviral effects. Studies have reported that cimifugin inhibits allergic inflammation by reducing the levels of cytokines. The aim of this review is to provide extensive information on the traditional use, ethnopharmacology, phytochemistry, pharmacology mechanism of action, and health products from Saposhnikovia divaricata .

Relationship between quality of life, depression and burden of mothers with child withсerebral palsy Background: Regular care and treatment of children diagnosed with cerebral palsy can be time-consuming and costly, increasing the risk of burden and depression, and adversely affecting quality of life. So there are many reasons why mothers' quality of life is poor socio-economic status and support related to the family, cerebral palsy from child care techniques and understanding of the disease the quality of life of mothers with sick children depends. There are few studies in Mongolia that assess the quality of life and other factors of mothers with cerebral palsy. We aimed assessing the relationship between quality of life, stress and depression in mothers with children with cerebral palsy. Materials and methods: The survey was conducted to the cross-sectional design of the analytical study based on the NCMCH. The study included 70 mothers with children with cerebral palsy. The survey data were collected using a general demographic questionnaire and three groups of questionnaires (WHOQOL-BREF, Stephen Zarit, Beck’s ). Quality of life and burden were measured as minimum <5, maximum 95 and minimum >20, maximum <88 respectively. Depression score measured as minimum >10, maximum <40. Results: The average quality of life of all mothers was 52.43 ± 11.95, environment was 44.8 ± 15.8. Maternal depression rates were 21 (30%), 90.0% of mothers had burden, and quality of life was statistically likely to be inversely related to depression and stress. Conclusion: The poor quality of life of mothers with children with cerebral palsy, high levels of depression and stress indicate the need for policies to reduce the quality of life.
