Background: Sarcopenia is a multifactorial geriatric syndrome characterized by age-related loss of muscle mass, muscle strength, and physical performance. In recent years, neurotrophic and neuromuscular biomarkers have been investigated as potential diagnostic indicators of sarcopenia; however, evidence regarding their sex-specific differences remains limited. Aim: To evaluate the sex-specific associations of serum BDNF, GDNF, and CAF22 levels with sarcopenia and muscle-related parameters among older adults. Materials and Methods: This analytical cross-sectional study included adults aged 60 years and older. Sarcopenia was defined according to the Asian Working Group for Sarcopenia (AWGS 2019) criteria. Serum BDNF, GDNF, and CAF22 levels were measured using ELISA. Group differences were analyzed using independent t-tests, correlations were assessed using Pearson correlation analysis, and diagnostic performance for sarcopenia was evaluated using receiver operating characteristic (ROC) analysis. Multivariable logistic regression analysis was also performed. Results: No statistically significant differences were observed in serum BDNF, GDNF, and CAF22 levels between sarcopenic and non-sarcopenic participants in either the male or female groups (all p>0.05). ROC analysis demonstrated AUC values ranging from 0.540 to 0.542 in males and from 0.508 to 0.530 in females for BDNF, GDNF, and CAF22. Multivariable logistic regression analysis revealed that age (OR=1.12, 95% CI: 1.04–1.21, p=0.003) and lower fat-free mass index (OR=0.78, 95% CI: 0.66–0.91, p=0.001) were significantly associated with sarcopenia, whereas BDNF, GDNF, and CAF22 showed no independent association with sarcopenia. Conclusions 1. No statistically significant sex-specific differences were observed in serum BDNF, GDNF, and CAF22 levels between sarcopenic and non-sarcopenic older adults (all p>0.05). 2. CAF22 levels were weakly negatively correlated with muscle mass and fat-free mass index in males (p<0.05), whereas BDNF levels showed weak positive correlations with handgrip strength and fat-free mass index in females (p<0.05). CAF22 levels also demonstrated a weak positive correlation with age (p<0.05). 3. ROC and multivariable logistic regression analyses indicated limited diagnostic utility of BDNF, GDNF, and CAF22 for sarcopenia (AUC=0.508–0.542), and none of these biomarkers showed an independent association with sarcopenia (all p>0.05). In contrast, older age (OR=1.12, p=0.003) and lower fat-free mass index (OR=0.78, p=0.001) were significantly associated with sarcopenia.

Background: The average age at menarche (AAM) among girls is influenced by various factors, including the socioeconomic status of the country, geographical location, and anthropometric characteristics. In Mongolia, limited research has been conducted on this topic Aim: This study aimed to compare the mean age at menarche among girls living in Bayanzürkh District of Ulaanbaatar and those in Uvs Province. Materials and Methods: A cross-sectional study was conducted between April and June 2025. The study participants included schoolgirls aged 8 years and older from general education schools located in Bayanzürkh District and Uvs Province. Statistical analyses were performed using R version 4.5.1 (RStudio 2025.05.1-513) Results: A total of 486 girls participated in the study. The mean age at menarche among the participants was 12.23±1.29 years. The mean age at menarche among girls aged 8–18 years in Bayanzürkh District was 11.84±1.19 years, while that among girls aged 8–18 years in Uvs Province was 12.97±1.15 years. Thus, girls in Bayanzürkh District experienced menarche 1.13 years earlier on average than those in Uvs Province. The difference in mean AAM between urban (Ulaanbaatar) and rural (Uvs Province) girls was statistically significant (p<0.0001). Conclusion The mean age at menarche among girls residing in Bayanzürkh District was significantly lower than that of girls living in Uvs Province, indicating a tendency toward earlier onset of menarche in urban areas.

Background: The Shimshin-6 formulation, composed of Rheum undulatum L., Hippophae rhamnoides L., Zingiber officinale Roscoe, Saussurea lappa C.B. Clarke, Sal ammoniacum, and Tronae veneni, has traditionally been used in the management of gynecological disorders such as amenorrhea, abnormal blood clot formation, and pelvic pain. It has also been widely applied in postpartum care to promote uterine contractility and to prevent complications, including hemorrhage and inflammation. However, its therapeutic potential in postpartum uterine involution has not been scientifically validated. Aim: To investigate the effects of the Shimshin-6 herbal formulation on postpartum uterine involution in rats Materials and Methods: This experimental study was conducted at the Research Center of the Institute of Traditional Medicine and Technology, following the methodology described by Zheng ZH et al. (2019). Postpartum rats were randomly assigned to four groups and received daily treatments for five consecutive days with either Shimshin-6 tablets at doses of 180 mg/kg and 90 mg/kg, Shimshin-6 decoction at 163 mg/kg, or physiological saline as a control. Serum concentrations of estrogen, progesterone, TNF-α, TGF-β1, and TGF-β3 were measured using commercially available ELISA kits (Shanghai MLBIO Biotechnology Co. Ltd, China). Following ethical euthanasia, uterine tissues were collected for histological examination, which included evaluation of uterine weight, endometrial thickness, myometrial structure, and glandular morphology. Results: Shimshin-6 treatment significantly reduced the uterine index and serum estrogen levels compared with the control group, while no significant difference was observed in progesterone concentration. The treatment also decreased tumor necrosis factor-α (TNF-α) levels and modulated growth factors in postpartum rats. Histological analysis further revealed that Shimshin-6 promoted uterine recovery, despite the presence of inflammatory cell infiltration and hemorrhagic changes in the uterine wall. Conclusion Shimshin-6 preparation exerts a promotive effect on postpartum uterine involution in rats.

Introduction: According to the World Health Organization (WHO) data from 2022, 19.9 million people were diagnosed with cancer globally, and 9.7 million people died from the disease. In recent years, the incidence of colorectal cancer (CRC) has been rapidly increasing, ranking 4th among all cancers with 18.4 cases and 8.1 deaths per 100,000 population. In Mongolia, 826 new cases of CRC have been registered over the past six years, with an incidence rate of 8.2 cases and a mortality rate of 5.03 per 100,000 population. It is projected that by 2030, the incidence will reach 13.28 cases and the mortality rate will rise to 8.72 per 100,000 population. We aimed to comprehensively examine the risk factors for colorectal cancer among the population of Mongolia, establish a scientific basis for early detection and prevention, and strengthen preventive measures. Materials and Methods: A case-control study was conducted from 2022 to 2024. The study enrolled a total of 305 subjects, including 98 patients with colorectal cancer, 101 patients with colon polyps, and 106 healthy subjects. The risk. questionnaire consisted of 50 questions divided into 10 sections. All statistical analysis was performed with SPSS version 23.0 software (SPSS Inc., Chicago, IL, USA) and P value <0.05 was considered statistically significant. categorical data was represented as numbers and percentages. Pearson’s chi-squared and Fisher’s exact test were used to compare categorical variables. Multivariate logistic regression was used to identify the risk factor associated with recurrence. The study protocol was approved by Ethics Review Committee of Ministry of Health of Mongolia on 17 March 2023 (approval number: 23/012). Results: The average age of the participants was 57.1±12.8 years. Among all study participants, 37.6% (115) were male and 62.4% (188) were female. Comparison of colorectal cancer incidence by age and gender revealed no statistically significant differences (p=0.021; p=0.422). Regular physical exercise was found to have a protective effect against colorectal cancer (p=0.076; OR 0.341 95% Cl 0.118-.0986). The frequency of fruit consumption, 4 to 6 times per week (p=0.008, OR 0.08, 95% Cl 0.01-0.45), frequency of vegetable consumption 4 to 6 times per week (p<0.00; OR 0.07, 95% Cl 0.02-0.19), no dining out (0.007, OR 0.3, 95% Cl 0.18-0.68), and meat consumption (p=0.001) are decreased risk of colorectal cancer. Conclusion The patient's age and the presence of colon polyps are risk factors for colorectal cancer, while regular physical activity and a diet rich in fruits and vegetables are protective factors that help reduce the risk of developing colorectal cancer.

Background: A drug related problem is defined by the Pharmaceutical Care Network Europe Association as an an event or circumstance involving drug therapy that actually or potentially interferes with desired health outcomes. One critical aspect of preventing such errors is proper dose adjustment, which plays a vital role in the diagnosis and treatment of disease. For instance, adjusting the dose of warfarin based on the patient’s INR level is essential. In a 1995 study conducted in England, clinical pharmacists recommended target doses of angiotensin-converting enzyme (ACE) inhibitors for patients with chronic heart failure. As a result, patients experienced a significant reduction in pulmonary and peripheral edema, along with improved exercise test outcomes. At the Mongolian-Japanese Hospital of the Mongolian Medical University of Science and Technology, it is important to analyze dosage-related issues identified by clinical pharmacists and inform healthcare professionals about common dosage selection errors and associated risks. Aim: We analyzed issues related to medication dosage. Materials and Methods: A retrospective study was conducted to examine problem related to dosage detected through prescription monitoring at the Mongolian Japanese Hospital of the Mongolian National University of Health Sciences from 2023 to 2024. Results: Out of a total of 2340 drug-related problem identified across five inpatient wards during this period, 581 (100%) were related to dosage. Clinical pharmacists performed prescription review on approximately 67% of all inpatients, which was consistent between years. However, medication-related problems tended to decrease from 41.1% (n=1499) in 2023 to 22.3% (n=841) in 2024 (p=0.05). The majority of dose-related problems, 75.6% (n=440), were overdoses. Medication-related problems were most common in the surgical department, with 59.5% (n=346) (p=0.001). The most frequent dosage-related errors involved exceeding the daily dose of diclofenac, administering higher- than-recommended doses of ceftriaxone, failing to adjust cefotaxime for renal function, and using inappropriate doses of metronidazole in patients with impaired liver function. The leading cause of these errors was failure to adhere to guideline-recommended dosing, which accounted for 71.3% (n=415) of cases (p=0.001). When dosage-related recommendations were provided to physicians before of treatment, acceptance rates increased by 14% (p=0.001). These interventions resulted in an estimated cost saving of 1.267.219₮ and a reduction of 363 injections. Conclusion Therefore, clinical pharmacist-led prescription review can help reduce the risk of dosage errors, lower associated healthcare costs, and alleviate the burden on medical staff.

Background: From the perspective of traditional medicine, researchers believe that the individual’s innate quality has a reciprocal effect on the physiological level. The study of body-specific quality differences is important for improving disease risk prediction, diagnosis, and treatment approaches. Therefore, explaining the features of traditional medicine with some physiological parameters and establishing the relationship between them is clinically significant and important for predicting disease risk and developing individualized treatment methods, which is the basis of this research. Aim: To establish the correlation between an individual’s innate unique constitution and specific biochemical indicators. Materials and Methods: The innate unique constitution of individuals was determined using electronic data, and the relationships between their characteristics and levels of uric acid, creatinine, urea, and glucose in the blood were analyzed. Results: A total of 102 participants were included in the study. Among them, the Shar-Khi constitution was the most prevalent, with 28 cases (27.45%), while the Khi-Badgan constitution was the least common, with 13 cases (12.75%). Individuals with the Khi-Shar constitution exhibited the highest urea level at 4.47 ммоль/л, whereas those with the Badgan-Shar constitution had the lowest at 4.15 ммоль/л. The uric acid level was highest in individuals with the Shar-Khi constitution at 316.15 µmol/L and lowest in those with the Badgan-Shar constitution at 261.36 µmol/L (p<0.001). Furthermore, individuals with the Badgan-Khi constitution had the highest creatinine level at 73.51 µmol/L, while those with the Badgan-Shar constitution had the lowest at 63.97 µmol/L (p<0.001). The blood glucose level was highest in individuals with the Khi-Badgan constitution at 4.59 ммоль/л and lowest in those with the Khi-Shar constitution at 4.21 ммоль/л. Kidney function indicators, particularly creatinine, significantly correlated with blood glucose levels (r=0.67, p<0.01). Higher uric acid and creatinine levels were associated with elevated blood glucose levels. These findings suggest that variations in urea, uric acid, and creatinine levels among different unique constitutions could be utilized to predict the risk of kidney disease or diabetes. Conclusion Depending on the individual characteristics of traditional medicine, kidney and blood sugar parameters are different and related to each other, and can assess the state of diabetes and kidney disease. Determining the inherent characteristics of an individual is considered important for improving the diagnosis, treatment, and prevention of diabetes and kidney disease.

Background: In traditional medicine, the Shimshin-6 formulation, which consists of Rheum undulatum L., Hippophae rhamnoides L., Zingiber officinalie Roscoe, Saussurea Lappa C.B.Clark, Sal ammoniacum, Tronae veneni, is recommended for women experiencing menstrual retention disorders. In recent years, Shimshin-6 has been widely used to promote postpartum uterine involution for women and our study aimed to evaluate and determine the acute and chronic toxicity effects of Shimshin-6. Aim: To evaluate and substantiate the acute and chronic toxicity effects of Shimshin-6. Materials and Methods: The acute toxicity of Shimshin-6 was evaluated using the rapid method described by V.B. Prozorovsky (1978) by administering intraperitoneal injections of the medicinal extract in white mice to determine the lethal dose. The active dose was determined following the methodology of I.P. Zapadnyuk (1983). Chronic toxicity was evaluated in Wistar rats according to the OECD 407 (2008) guidelines. The test animals were administered Shimshin-6 in tablet form (90 mg/kg and 180 mg/kg) and decoction form (tang) (162 mg/kg) daily for 60 days. At the end of the experiment, biochemical and complete blood analyses were conducted, along with histopathological examination of major organs. The study was conducted with ethical approval granted by the Ethics Committee of the Mongolian National University of Medical Sciences (MNUMS) on October 25, 2024. Results: The LD50 for Shimshin-6 tablets was 4.47 (3.39–5.1) g/kg, indicating low acute toxicity based on the K.K. Sidorov classification. The LD50 for the decoction form was 8.1 (7.1–9.4) g/kg, suggesting it is non-toxic. Regarding chronic toxicity, platelet count was significantly reduced compared to the healthy control group: Shimshin-6 tablet group: 46% reduction at 90 mg/kg and 29.7% reduction at 180 mg/kg. Shimshin-6 decoction group: 60.5% reduction at 162 mg/ kg. Additionally, hemoglobin levels in the decoction group (162 mg/kg) decreased by 15.7% (p<0.05). Biochemical analysis showed a 36.3% reduction in total cholesterol (LDL-C) levels in the tablet group (180 mg/kg) and decoction group (162 mg/kg) compared to the control (p<0.05). Conclusion Shimshin-6 tablets showed low acute toxicity in experimental mice. However, long-term administration may lead to a reduction in platelet count.

Background: The first confirmed case of COVID-19 in Mongolia was reported on November 11, 2020. In response, the government imposed a nationwide lockdown, which significantly impacted the population’s mental health. Heightened levels of stress, anxiety, loneliness, and depression during the pandemic altered individuals’ psychological stability and behavior. Personality traits—defined as relatively stable patterns of emotion, cognition, and behavior—play a key role in stress responses and emotional regulation under pressure. Emerging evidence suggests that these psychological factors may influence the immune system’s responsiveness, including vaccine-induced antibody production. Aim: To evaluate the association between post-vaccination antibody responses and personality types following two doses of COVID-19 vaccines. Materials and Methods: A total of 738 participants who received two doses of COVID-19 vaccines (AstraZeneca ChAdOx1, n=29; Pfizer-BioNTech, n=119; Sinopharm BBIBP, n=590) and had no prior SARS-CoV-2 infection were enrolled. Serum samples were collected 21–28 days after the second dose, and SARS-CoV-2 RBD (S) IgG antibodies were measured using ELISA (Proteintech Inc., USA). Personality types were assessed using a 56-item temperament questionnaire developed by A. Belov, categorizing individuals into classical temperament types (choleric, phlegmatic, sanguine, melancholic). Logistic regression and ROC analysis were used to examine associations between personality types and antibody response. Results: The presence of an antibody response was significantly higher among individuals with a melancholic temperament, and significantly lower among those with a phlegmatic temperament. Furthermore, antibody titers were higher in participants with melancholic and sanguine temperaments and lower in those with a phlegmatic type. Conclusions 1. During the early period following the second dose of COVID-19 vaccination, the antibody response was higher in individuals with a pure melancholic temperament, while it was lower in those with a phlegmatic temperament. 2. After the second dose of the Sinopharm BBIBP COVID-19 vaccine, antibody titers were higher in individuals with pure melancholic and sanguine temperaments, and lower in those with a phlegmatic temperament.

Background: Vaginal candidiasis is a highly prevalent infectious disease among women caused by a wide range of pathogenic organisms. Although it can be treated with standard pharmacological methods, it has detrimental effects on women’s reproductive health. The absence of research to date on the anti-vaginal inflammatory effects of Jirug-6 suppositories - a traditional formulation derived from ancient medicinal recipes and long-used in traditional mongolian medicine has provided the rationale for conducting this study. Aim: Study of the effects of Jirug-6 suppositories on the vaginal inflammatory lesion model induced by Candida albicans. Materials and Methods: To establish the vaginal inflammatory lesion model in experimental animals, the inoculum was prepared according to the McFarland standard method, and 10 µL of the inoculum was intravaginally administered daily for 4 consecutive days. Fifty-six mice with induced vaginal candidiasis were divided into 7 groups. On treatment days 1, 3, 5, 7, and 10, the vaginal cavity of the mice was washed with 100 µL of phosphate buffer. From the lavage fluid, 20 µL was collected, mixed with 480 µL of phosphate buffer, and thoroughly homogenized. Using a 20 µL micropipette, three aliquots were inoculated onto Sabouraud Dextrose Agar (SDA) medium and incubated at 37°C for 48 hours. Colonies were counted, and at the end of the experiment, serum was isolated from blood samples, and IFN-γ and IL-10 levels in the samples were quantified using ELISA. Histopathological analysis was performed on vaginal tissues from the experimental animals. Results: In the experimental animals, Jirug-6 suppositories 0.4 mg/kg dose exhibited the mildest clinical signs of hyperemia, swelling, hemorrhage, infiltration, or fluid loss into soft tissues in the vaginal and cervical regions (p<0.01). For cervical inflammation, Jirug-6 suppositories 0.4 mg/kg demonstrated a strong anti-inflammatory effect with a score of 1.99±0.78, which was comparable to the positive control group (p<0.01). In serum, the concentrations of IFN-γ and IL-10 in Jirug-6 suppositories 0.4 mg/kg were determined to be 8.18±0.61 and 7.91±1.30, respectively, showing reduced levels similar to those of the positive control group (p<0.01). Conclusions 1. Jirug-6 suppositories reduce inflammatory symptoms and suppresses fungal dissemination during the vaginal lesion model induced by C. albicans. 2. At a Jirug-6 suppositories 0.4 mg/kg demonstrates anti-inflammatory effects by increasing IFN-γ concentration and decreasing IL-10 concentration in the C. albicans-induced vaginal lesion model. Furthermore, it enhances immunity and reduces swelling during inflammation, exhibiting positive therapeutic effects against clinical symptoms.

Background: Specifically, stomach cancer ranks as the fifth leading cause of cancer morbidity and mortality worldwide. Early-stage detection significantly improves survival rates, with over 90% of patients diagnosed at stages I and II living beyond five years. To improve the early detection of gastric cancer, it is necessary to complement the conventional method of endoscopic examination with biomarker analysis. We aimed to compare biomarkers such as pepsinogen C (PGC), matrix metalloproteinase 2 (MMP2), matrix metalloproteinase 9 (MMP9), and the cell proliferation marker Ki-67 with immunohistochemical analysis. Purpose: A comparative study and evaluation of biomarkers for the early detection of gastric cancer. Materials and Methods: The study was conducted using a retrospective cohort design. Research ethics issues were discussed at the meeting of the Medical Ethics Control Committee of the Ministry of Health on October 13, 2023, and permission to start the research was obtained (Resolution No. 23/051). The information was gathered based on the criteria for K29.3, K29.4, K31, and C1 diagnoses according to the international ICD 10 classification, and participants were selected accordingly. Proteins such as PGC, MMP2, MMP9, and Ki-67 were examined using a tissue microarray kit and evaluated through immunohistochemical analysis. Results: Negative gastric tumor markers PGC, Ki-67, MMP2 and MMP9 were evaluated by immunohistochemical analysis. The mean PGC protein staining values were 6.20±2.61 for chronic superficial gastritis, 5.45±2.47 for atrophic gastritis, 3.61±2.0 for metaplasia, and 3.31±1.75 for gastric cancer, with statistically significant differences between the groups (P<0.001). The mean Ki-67 protein staining values were 0.1 ± 0.4 for chronic superficial gastritis, 0.33 ± 0.55 for atrophic gastritis, 0.09 ± 0.39 for metaplasia, and 2.62 ± 0.78 for gastric cancer, also showing statistically significant differences (P<0.001). The mean MMP2 and MMP9 protein staining values were 0.2±0.76 and 1.2±2.04, respectively, for chronic superficial gastritis; 0.28±0.52 and 3.28±2.82 for atrophic gastritis; 0.35±1.04 and 1.12±1.45 for metaplasia; and 1.38±2.11 and 5.29±2.51 for gastric cancer, with all differences being statistically significant (P<0.001). Conclusion PGC protein, a negative tumor marker, decreases during the transition from a gastric cancer precursor to cancer. MMP2 protein, a marker of cell migration and metastasis, has little diagnostic value, while the expression of MMP9 and the Ki 67 are highly effective in gastric cancer. Immunohistochemical analysis of endoscopic biopsy tissue to detect the negative tumor marker PGC, the positive marker Ki-67, and MMP9 can be used for early detection of gastric cancer.
