Diagnosis 2024;110(3):25-29
Homework plays a crucial role in enhancing academic performance, in especially language acquisition. For medical students, English proficiency is essential for accessing global knowledge and succeeding in their field. This study aims to examine the relationship between English homework completion timing and academic performance among medical students. A total of 48 students (70% female, 30% male) from different proficiency levels (beginner to upper-intermediate) participated. Data were gathered through an online survey, including sections on homework timing, average exam scores, and reasons for homework timing. Statistical analysis revealed a moderate negative correlation (-0.267) between homework timing and academic performance, suggesting that students who delay homework completion tend to perform slightly lower. Results showed that most students prefer to complete homework the day before a class (54%), while others favor completing it 2-3 days later (40%), valuing retention over time. Students’ reasons for their timing choices varied, with 42% citing other coursework as a barrier to earlier completion. The findings underscore the importance of time management and self-regulation in optimizing homework habits to improve English proficiency and academic outcomes. This study provides insights for educators to guide medical students in developing effective homework strategies that enhance both language learning and academic performance.

To evaluate the efficacy and safety of bevacizumab monotherapy or combined with laser versus laser monotherapy in Mongolian patients with visual impairment due to diabetic macular edema.Prospective, randomized, single-center, a 12 month, laser-controlled, clinical trial. Participants: One hundred twelve eligible patients, aged ≥18 years, with type 1 or 2 diabetes mellitus and best corrected visual acuity (BCVA) in the study eye of 35 to 69 Early Treatment Diabetic Retinopathy Study (ETDRS)letters at 4 m (Snellen equivalent: ≥6/60 or ≤6/12), with visual impairment due to center-involved diabetic macular edema (DME). Methods: Patients were randomized into three treatment groups:(I) intravitreal bevacizumab monotherapy (n=42), (II) intravitreal bevacizumab combined with laser (n=35), (III) laser monotherapy (n=35). Bevacizumab injections were given for 3 initial monthly doses and then pro re nata (PRN) thereafter based on BCVA stability and DME progression. The primary efficacy endpoints were the mean change in BCVA and central retinal subfield thickness (CRST) from baseline to month 12.Bevacizumab monotherapy or combined with laser were superior to laser monotherapy in improving mean change in BCVA letter score from baseline to month 12 (+8.3 and +11.3 vs +1.1 letters; both p<0.0001). There were significant difference detected between the bevacizumab and bevacizumab combined with laser treatment groups (p=0.004). At month 12, greater proportion of patients gained ≥10 and ≥15 letters and with BCVA letter score >73 (Snellen equivalent: >6/12) with bevacizumab monotherapy (23.8% and 7.1% and 4.8%, respectively) and bevacizumab + laser (57.1% and 28.6% and 14.3%, respectively) versus laser monotherapy. The mean central retinal subfield thickness was significantly reduced from baseline to month 12 with bevacizumab (−124.4 μm) and bevacizumab + laser (−129.0 μm) versus laser (−62.0 μm; both p<0.0001). Conjunctival hemorrhage was the most common ocular events. No endophthalmitis cases occurred.Bevacizumab monotherapy or combined with laser showed superior BCVA improvements over macular laser treatment alone in Mongolian patients with visual impairment due to diabetic macular edema.

Introduction:
Urinary tract infections (UTI) are at the second place in the frequency of all causes of infection after respiratory ones. The UTI requires appropriate antibiotic treatment. 85% of UTI predictive antibiotic treatment without confirmation by bacteriological analysis. This is one of the major causes of drug resistance, especially in K.coli. Urine bacteriological tests do not show bacterial culture in all cases where the number of bacteria in the urine exceeds the reference level. Therefore, there was a need to establish criteria for urine bacteriology test based on the results of urine sediment analysis.
In 20I7, a new fully automated Sysmex UF-5000 urine sediment analyzer was installed in the laboratory department of Medipas Hospital. The features of this analyzer include counting the number of bacteria in the urine, distinguishing between gram-positive and negative, homogeneous and mixed forms, and counting the formed elements in the urine. This feature made it possible to compare the number of bacteria and leukocytes in the urine with the results of urine bacteriology tests.
Goal:
Determine the relationship between the number of white blood cells and bacteria in the urine measured by the Sysmex UF-5000 urine sediment analyzer and the results of the urinary bacteriological test.
Objectives:
Compare the number of urine bacteriaand leukocyte measured by using the Sysmex UF-5000 urine sediment analyzer with the urine bacterial culture, and calculate the correlation.
Materials and methods:
The study is analytic cross-sectional study, analyzed the results of a total of 159 people who analyzed a urinalysis and urine bacteriological test at the Medipas Hospital Laboratory in 2017-2019 years.Urine samples were collected in a 100 ml, disposable sterile container in accordance with the instructions for taking urine midstream.Urine analysis was performed within 2 hours of sampling with a fully automatic urine sediment analyzer Sysmex UF-5000 Japan. Urine bacteriological analysis was performed on a lul sterile loop of urine specimens, inoculated into 5% blood agar from Hungary's BioLab, Sabouraud agar, and Chromogen agar from Biomerieux France, and incubated for 24 hours in an incubator at 37°C. Bacterial identification and antibiotic susceptibility tests were analyzed using the "Vitek-2" analyzer from the manufacturer Biomerieux France. Bacterial and leukocyte counts data measured by the Sysmex UF-5000 analyzer and urinary bacteriological analysis data were performed using SPSS23 software.
Results:
A total of 159 urine samples were tested for bacteriological analysis, of which 81 (50.9%) were bacteria over 105 CFU/ml or urine positive culture UTIs, 78 (49.1%) were nonsignificant bactcruria and urine negative culture.The average number of bacteria measured in the urine of 81 samples with urine positive culture above 105 CFU/ ml was 46491/ul (1168-100000 BACT/ul).
The average number of bacteria measured by the urine sediment analyzer of 78 samples with urine negative culture was 2645 BACT/ ul (2-57280 BACT/ul). To calculate more accurately estimate the average number of bacteria in 81 urine specimens with positive culture, the average number of bacteria in 17 (21%) samples was 4753 BACT/ul, measured in relatively low bacteria numbers of 1168-9450BACT/ul. The average leukocyte number in the urine of 81 samples with positive culture was 472.2 WBC/ul, and the average leukocyte number in the urine of 78 samples with negative culture was 87.7 WBC/ul.There is a strong correlation between the number of bacteria measured by the urine sediment analyzer and urine bacterial positive culture, which is 0.8 or statistically significant (p<0.001).The correlation coefficient of the number leukocytes measured by the urine sediment analyzer with in the urine positive cultureof bacteriological tests was 0.6 or moderately of statistically significant (p=0.005).There is a statistically significant relationship (p=0.001) between the number of bacteria in the bacterial positive culture population and the number of leukocytes.
Discussion:
Of the 81 cases of urine bacterial positive culture, 78 (96%) were female, indicating a high prevalence of UTI among women. According to the results of the Fabio Manon's study, the number of leukocytes in the urine is 160-340 WBC/uL and the number of bacteria is 15000-30000 BACT/u,L in the case of UTI, which is approximate results compared to the our study results.Based on the results of the urine sediment analysis, indications for a urine bacteriological test should be made.
Based on the results of urinary bacteriological tests, the choice of antibiotic treatment is the best treatment for urinary tract infections and a way to prevent of antibiotic resistance to UTI.
Conclusions
The number of bacteria measured by a Sysmex UF-5000 urine sediment analyzer is directly related to the bacterial culture urine bacteriological test. If the number of bacteria in the urine is measured above 4753 BACT/ul, it can be considered as an indication for urine bacteriological analysis. Although the number of leukocytes in the urine measured by the Sysmex UF-5000 urine analyzer is moderately correlated with bacterial culture in urine bactcriologucal tests, it is a key indicator of the degree of inflammation of the urinary tract.

Excipients are important in the composition of drugs and are the most important requirements for maintaining
the stability of drug form, dosage, and physicochemical parameters. Excipients act as protective agents,
bulking agents and can also be used to improve bioavailability of drugs in some instances Auxiliary
substances included in the composition of medicines are classified as natural, animal, synthetic and
semisynthetic. Excipients can become inactive due to chemical, microbiological and physiological effects.
Commonly used pharmaceutical excipients are fillers, stabilizers, preservatives, flavor and aroma modifiers,
binders, disintegrants, lubricants, lubricants, solvents, and coating agents. Excipients can be considered as
indispensible component of medicinal products and in most of the formulations they are present in greater
proportion with regards to active pharmaceutical ingredient, as it forms the bulk of the formulation it is
always necessary to select an excipient which satisfies the ideal properties for a particular excipient. In this
review, materials about coating agents widely used in pharmaceutical practice were compiled from electronic
databases such as Pubmed, Google Scholar, and other scientific web pages, using keywords such as Drug
excipient interaction, Stability in Oral Solid, and Excipient. .

The incorporation of botanical elements such as Inula helenium L., Astragalus mongolicus Bge.,
Iris tenuifolia Pall., Ribes diacanthum Pall., and Oxytropis pseudoglandulosa Grubov plays a pivotal role in the formulation of immune-enhancing and kidney-protective Mongolian traditional medicines. These herbal constituents bear rich historical significance in traditional remedies. Ensuring the purity of these herbs is a vital stride in the production of efficacious supplements and medications. Thus, meticulous decontamination of microorganisms assumes paramount importance. The selection of an appropriate sterilization method is important for manufacturers. Sterilization methods divide within three main categories: thermal, chemical, and radiation. This spectrum encompasses many techniques, ranging from moist heat and dry heat to gamma irradiation, ethylene oxide, ozone, and UV treatment. This comprehensive review discusses the efficacy of gamma irradiation, dry heat, moist heat, and chemical treatments, presenting a comparative analysis of their merits. Practically, heat sterilization emerges as a simple and cost-efficient choice. The utilization of an autoclave, subjecting powdered spice paprika to temperatures between 108-125°C for 120 seconds, yielded a substantial reduction in microbial load without compromising the integral bioactive compounds. Gamma
irradiation, a common practice in the healthcare and pharmaceutical sectors, stands as another choice in the area of sterilization techniques. Beyond sterilization, upholding rigorous standards of sanitation and hygiene remains a key in the preparations of medicinal plants.

Introduction:
Over 800,000 people in the world contract HCC each year and approximately 700,000 die from the disease. HCC is the 6th most common cancer in the world. HCC is the 3rd leading cause of cancer deaths in the world. 2/3 of liver cancer deaths are caused by hepatitis. In the U.S, HCV infection is the more common cause of HCC, while in Asia and Africa, HBV is more common. Mongolia ranks first in the world in mortality from liver cancer, indicating the need for early detection and treatment of cirrhosis. Sysmex Corporation has introduced for HISCL series analyser, a new cirrhosis marker M2BPGi of non-invasive, blood-testing. In 2016, the test was introduced
at Medipas Hospital in Orkhon province. It is possible to study the advantages and significance of the marker for use in clinical practice.
Materials and methods:
From a total of 385 patients who underwent M2BPGi marker testing in 2016-2017Medipas hospital laboratory, data from a total of 283 patients tested for hepatitis B and C virus and M2BRGi markers were selected. A comparison of age, sex, and test parameters of a total of HCVab and HBsAg positive 172 patients tested for Total bilirubin, GPT, GOT, GGT, AFP and M2BPGi. HCV Ab, HBsAg, AFP, M2BPGi markers were analyzed by SysmexHISCL-5000 fully automated immunological analyzer, Liver function tests were performed with a fully automatic biochemical analyzer JEOL Biomajesty BM6010/C.
Results:
Of the M2BPGi marker tested 283 patients 94 (33%) were infected with the C virus, 78 (28%) were with the B virus,11 (4%) were co-infected with B and C viruses, 100 (35%) no any viral infection. Of the 172 patients diagnosed with hepatitis B and C virus infection, 97 (56%) were male, 75 (44%) were female. In terms of age, 72% of the population is over 45 years old.
Of the 172 patients, 115 (67%) had M2BPGi marker abnormal or > 1.0 COI. Of the M2BPGi marker abnormal patients, 47 (41%) were infected with the B virus and 68 (59%) with the C virus. In terms of age, 27.7% of hepatitis B patients and 10.3% of hepatitis C patients were under 45 years of age, 72.3% of hepatitis B patients and 89.7% of hepatitis C virus patients were over 45 years of age.
Hepatitis B and C viruses are slightly more common in men than in women. The majority of patients infected with the hepatitis virus over the age of 45. The majority of patients with hepatitis virus have abnormal liver function. Increased M2BPGi markers in people under the age of 45 with hepatitis B virus infection are relatively higher for hepatitis B virus infection than for C virus infection.
Conclusions
The M2BPGi marker was abnormal in 67% of hepatitis virus infected patients. It has been observed that the probability of an increase in M2BPGi marker is slightly higher in hepatitis C virus infection than in hepatitis B virus infection.
