BACKGROUND: To highlight from the varies researches, made by global scientists, about principle for students’ studying procedure, that students get enough information from the environment, habitation, media of communication before they run into school. It’s very important that students’ occupied knowledge and practice should be based on their daily life, associated with their future job, real requirement, and interest. The learner should be not only a knowledge owner, but also a knowledge creator to have a self-educated skill based on an activity. Most medical students encounter with high pressure in their first school year, and it has a high risk to drop their school at their first year, such as in Scotland 9.9% (Scotsman, 2010), in Australia 33% (Hinde, 2008) in Southern Africa 40% (Macgregor, 2007). We chose this article in our research to study the psychology of the premedical training students and to determine if it has the relevance with educational achievement. METHODS: The research has done with instant analytical research paper sample, and got a standard survey about adaptation and psychological changes in the 1st course of premedical training of medical school. After identifying the normal distribution of variables, we considered the differences between indexes with percent variables with Chi-Square distribution method, and differences between averages with T-Test methods, and also it could have true probability statistic if the meaning of “p” reaches less than 0.05. We have sum up the quality research data by their content groups. RESULT: The overall number of students, who has been involved in our survey, has reached 106 and from the ratio of genders and 1st, 2nd term’s GPA, we can analyze that without gender differences the students’ GPA has been improved in the 2nd term. The highest value of the students’ GPA was 1.47 and increased from C (2.49) mark to A (3.22) mark. The comparison of the 106 students’ valuation of their social adaptation by themselves in the first and second term, who has been involved in our survey, has shown that the highest value of the first term was 18.85, which the question was “How many times have you missed your class in last 2 weeks?” and the answer of the same question in the end of the second term has decreased to 1.11 average meaning, which shows that the students’ attitude for missing classes has decreased. The ratio of total number of students’ evaluation of social adaptation and 1st, 2nd term’s GPA, has been shown positive ratio of the GPA to the social adaptation, which was counted by Correlation formula. CONCLUSION: According to the students, who has involved in our study, have elevated their 2nd term GPA than 1st term, The adaptation of the students, who is studying in premedical training of the medical school, have been improving in the end of the school term, It’s giving a positive relevance between social adaptation and GPА of the students, who is studying in premedical training of the medical school.

Background: Complete blood count (CBC) is one of the most widely used clinical tests, offering a high-quality, inexpensive, and routine diagnostic tool for various diseases and for monitoring treatment outcomes. Due to modern technological advancements, blood cells are now measured in greater detail, with 36 parameters being evaluated. The prevalence of diabetes mellitus (DM) is rapidly increasing, not only globally but also in our country. This rise in prevalence leads to numerous adverse consequences, including delayed diagnosis, poor control, an increase in chronic complications, and treatment failure. Hyperglycemia is a predisposing factor for chronic inflammation, and a relatively new inflammatory marker, the neutrophil-to-lymphocyte ratio (NLR), may be useful for assessing diabetes control. In recent years, NLR has been studied as a composite biomarker that more effectively reflects systemic inflammation and is easier to detect compared to other inflammatory markers. An increase in neutrophil count and percentage indicates chronic, low-grade, toxic, and non-specific inflammation, while a decrease in lymphocyte count suggests insufficient immune regulation. Thus, an elevated NLR not only reflects the immune system’s functional state in chronic inflammation, but it is also studied as a reliable and selective marker of systemic inflammation in chronic diseases. NLR is considered more stable than the total leukocyte count, is less affected by physiological and pathological factors, is inexpensive, and can be incorporated into daily clinical practice. Aim: To study the relationship between the neutrophil-to-lymphocyte ratio in a complete blood count and diabetes control and complications Materials and Methods: A cross-sectional study was conducted involving 145 patients with type 2 diabetes mellitus, who were treated at the Endocrine Clinic of the Mongolian-Japanese Hospital, Mongolian National University of Medical Sciences. Data on the neutrophil-to-lymphocyte ratio (NLR), glycated hemoglobin (HbA1c), and diabetic complications, including retinopathy, neuropathy, and foot complications, were collected from the Carte-Hospital Management System. Based on the frequency distribution of the NLR parameter, the values were classified into three groups: low, medium, and high. These groups were subsequently compared with glycemic control and complications using correlation and linear regression analyses, with statistical significance set at p<0.05. Results: The mean age of the study participants (n=145) was 57.3±12.9 years, with 46.8% (n=131) being male. The mean duration of diabetes was 9.6 years (range: 1-31 years), and the mean HbA1c level was 8.6±2.47%. Among the participants, 59.3% (n=86) exhibited poor glycemic control. Regarding complications, 52.3% of participants experienced at least one diabetes-related complication. Of these, 25.2% had one complication, 13.3% had two, and 7.1% had three or more. The most common complications were retinopathy (25.7%), nephropathy (18.6%), and macrovascular complications (11.9%). A statistically significant increase in the mean HbA1c level was observed across groups stratified by NLR levels (p=0.003). Linear correlation analysis revealed a statistically significant positive correlation between HbA1c levels (r=0.194, p=0.001) and the number of chronic diabetes complications (r=0.162, p=0.002). Conclusion The NLR level is positively correlated with both diabetes control and the occurrence of chronic complications. As an inexpensive and easily accessible test, it can be used for daily monitoring and early detection of complications.
