Background: In recent years, kidney complication of diabetes became the basic cause of the end stage of renal disease in many countries around the world and then primary kidney disease goes on the 2-3 places. Due to the fact that diabetes mellitus turns more and more into non-communicable worldwide epidemic, we faced the increase in kidney complication which is one of form of micro vascular complications. So, illness of every 1-2 in three patients to undergo a renal replacement therapy has been diagnosed as diabetic nephropathy and of course nephrologists could not leave this fact without their attention. Goal: To study a change in the kidney structure with type 2 diabetic patients. Materials and Methods: Within the scope of the research 35 autopsied passed way because of the type 2 diabetes in clinical hospitals. According to Tervaert classification of diabetic kidney pathology issued by American Society of Nephrology in 2006, changes in glomerular structure were divided into 4 classes. Ordinary staining methods as hemotoxilin eosin, Van Gizonestaning connective tissue, Periodic Acid- Schiff standing have been used.Results: 35 autopsied in total, including 23 male (65.7%) and 12 female (34.3%) were covered by this research. And glomerular basement membrane thickening discovered in 51.4%, mesangial matrix expansion in 34.2%, Kimmelstiel-Wilson nodule in 20% and advanced glomerulosclerosis in 8.5% of total cases, respectively.Conclusions:1. It is found that diabetic kidney can be classified by Tervaert classification using ordinary standing and PAS reaction on the light microscope.2. However, we faced an essential necessity to be armed with immunofluorescence and electron microscope for the purpose to improve diagnostic examination and establish classes more accurately.3. Today when the medical science develops as evidence-based medicine, a starting the kidney biopsy samples assaying become the vital issue in comparative studying the clinical stage of diabetic kidney pathology.

Introduction: Last Decades, Date by date medical developments providing friendly, high-efficiency treatment equipment and services in developed countries are working toward an advanced, as our country medical services are trying to that country’s technology has been introduced. In our country every day there is only surgical care necessary to endocrine gland disorders, including most common thyroid surgery. It is open and robotic assistant endoscopic surgery in the world. But robotic assistant endoscopic surgery is too expensive and impossible in our country. Thus we chose Thunderbeat for open thyroid surgery in especially huge enlarged goiter and vascularized goiter to try prevent bleeding, recurrent laryngeal nerve palsy and post operation hematoma and other complications Thunderbeat is new generation instrument combines an advanced bipolar clamp to the existing ultrasonic cutter. Materials and Methods: M 51-years-oldwoman was admitted to Mongol Hyundae hospital because of front of neck pain, multi nodular goiter, tachycardia, sweaty and not controlling emotion. Anamnesis: She diagnosed to Thyrotoxicosis in 2005 and she took medicine last ten years but not controlling that poisoning. Status locals: Huge enlarged goiter in front of her neck Treatment plan: 1. Preoperative Preparation 2. Operation: Open total thyroidectomy 3. Medicine 4. Wound dressing 5. Observation We did operation after day of admission day, Patient is placed in a Semi erect position with a folded sheet underneath the shoulders so that the head is sharply angulated backward on the multifunctional surgical table under general anesthesia. We used thunderbeat from muscular to all procedures, dissection both thyroid gland and isthmus after Kocher skin incision and sub skin tissue dissected. There is no complication while procedure and post operation days Result: Nodular hyperplasia of thyroid gland with focci of micro adenomatous change Conclusion: Thunderbeat in use open thyroid surgery first outcomes blood loss than 30ml, no injury of recurrent laryngeal nerve and no penetration ligament of Berry while procedure, second outcomes no hematoma, painless, wound healing process faster and short time hospitalization.

BackgroundIgA nephropathy and MPGN are common glomerulonephritis in the world that progresses slowly andrenal function can even remain unchanged for decades. Clinically, it presents by isolated hematuria,proteinuria. Histologically, IgA nephropathy presents with acute glomerular damage, mesangial cellproliferation, endocapillary leucocyte infiltration, and crescent formations, these lesions can undergoresolution with sclerotic healing. Since 2013, renal biopsy has been done at the First Central Hospitalof Mongolia a few times. However, the confirmative diagnosis of IgA nephropathy and MPGN remainunknown in Mongolia by renal biopsy. Therefore, we intended to test renal biopsy techniques andconfirm its diagnosis by renal biopsy at the Second Central Hospital of Mongolia.MethodsUltrasound guided renal biopsy had been done for four patients by nephrologist at the Departmentof Nephrology of the Second Central Hospital of Mongolia. All four specimens were evaluated assatisfactory which show more than 8 glomerulus under the light microscopy. Each renal cortical tissuewas divided into two tips: one piece for routine H&E stain and special stains, including Masson’strichrome, and PAS stain; another piece for immunofluorescence by frozen section, which werestained with IgG, IgM, IgA and complement component 3 (C3). Each case was screened by threepathologists.Results:The case which shows mesengial widening, mesengial hypercellularity under the light microscopyor mesangial granular deposition of IgA and C3 by immunofluorescence was diagnosed as IgAnephropathy. We obtained crescent formation with glomerular adhesion in most cases. In addition, weobserved secondary MPGN in one case, which is caused by hepatitis C virus infection.Conclusion: Probably, it is a new step for developing pathologic diagnosis for nephrology in Mongolia.We needs further study for improving renal biopsy technique and confirming the diagnosis of IgAnephropathy and MPGN using electron microscopy and pathological report by oxford classification forIgA nephropathy.

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.
