Introduction: Orthopedic surgery is a highrisk of surgical formation of thromboemboliccomplications.Many researchers are exploringprevent surgical complications.Anticoagulanttreatment is the first choice to preventthromboembolic complications.Artificial jointreplacement surgery has been made in 2008,in National First Central Hospitals (NFCH).Wehave not guideline of anticoagulant treatmentafter surgery and have not principle of choisefollow-drug treatment and unclear testingschedule to monitor anticoagulant treatment,that has become the basis for this study. Westudied by comparing a comparative benefitfor anticoagulant treatment of unfractionatedand low molecular weight heparin results.And studied thromboembolic complications,monitoring test of anticoagulant treatment,fatal bleeding, changes hemostasis ofanticoagulant therapy in both groups. Thesurvey results in practice is doing researchaims to introduce and review the results of thelong-term results.Materials and Methods: Included in thesurvey about 1,400 patients, who had kneeand hip replacement surgery in 2008-2016, inJoint Center of NFCH. All patients are dividedin three group. The first group is control group,do not use anticoagulation treatment, in thesecond group used unfractionated heparin andin the third group used low-molecular-weightheparin.Each group studied comparativewhether thromboembolic complications anddeath caused by thromboembolic, fatalbleeding.Between surgical complication andanticoagulant therapy relationship to investigatethe relationship the correlation is likely trueof 95%. Caused by other thromboemboliccomplications detected cases were removedfrom the study.Results: Control groups has not hospitalmortality, but has 3 cases of sudden death ina after discharge.Hemostasis is longer (INR1,3-1,5) in the second group. There hospitalmortality occurred in 1 (cardiac infarction),and thromboembolic complications 1 (arterialthrombosis in the jugular) in the third group.Low molecular weight heparin are no changeshemostasis, it is strongly dependent (r=0,8).Also in this group there is no fatal bleeding.Conclusions: Orthopedic surgery isnecessary for prevention of thromboemboliccomplications are showing from in controlgroup has sudden death.2 groups have not fatalbleeding when used heparin in normal doses.Other countries researchers conclude lowmolecular-weight-heparin is more effectivethan unfractionated heparin, our study is notvisible correlation reliability.When used lowmolecularweight heparin, hemostasis is notchanged is showing a strong dependence.

Introduction: We performed more than1200 arthroplasty surgeries at National FirstCentral Hospitalfrom 2008, so we haveour surgical technique and experiences.Thepurpose of this study is to assess our surgicalresults and complications after surgery forfemoral neck fracture made in Joint Center,National First Central Hospital, and tocomparingsimilar studies in other countries,and to develop the best optionsurgicaltherapy.Materials and Methods: Between 2008-2015, hip replacement surgery accountedatotal of 168 cases, that was 13.9% allof replacement surgery. A retrospectiveanalysis of patient database based onhospital discharge data and medical recordswas performed. The medical records ofthese patients were reviewed to confirmthe presence of a surgical site infection asdescribed by the Centers for Disease Control(CDC)/NNIS guidelines.Results: Between 2008-2015, in theJoint Center,National First Central Hospital,are seeing increasing number of patientswith hip replacement surgery each year.The cause for hip replacement surgery isaseptic necrosis (42%), at second is femoralneck fractures (22%). Joint Center,NationalFirst Central Hospital currently not providedemergency trauma care center. Therefore,younger patient with femoral neck fracturewas not to happen duringresearch. Olderthan 60 year patients with osteoporosis and,in some cases with nonunion, was doneforhip replacement surgery. The averageage of 75.7 (61-87).Bipolar hip arthroplastywas 14 cases all of 36 patients with femoralneck fracture.9 (5,31%), complications ariseall of hip replacement surgery (168 cases).Including: Infection - 1 (0.59%), sliding - 1(0.59%), dislocation - 2 (1.78%), fracture- 2 (1,18%), nerve injury - 2 (1,18%) andpostoperative mortality - 1 (0.59%).Conclusion: Internal Fixation- for patientage under 60 andgood bone quality. Thatoperation complication is femoral headnecrosis, not healing /nonunion/ delivery ofa lot of research that shows focus. Further,most surgery for femoral neck fracture is hipreplacement that is expected to be widelyavailable.

Introduction: Artificial joint replacementsurgery started in 2008, in Joint centerof National First Central Hospital. Hasexperienced a variety of post-surgicalcomplications.Postoperative infectiouscomplications, prevent and investigate thecauses of the research is carried out todetermine whether the opportunity.Materials and Methods: Facilitiesrandomly selected cases difficult patientswith postoperative septic, and analyzedby descriptive method. In all cases,Bacteriological analysis of the clinicallaboratory department of joint fluidsamples received. We determined artificialjoints causes of postoperative infectiouscomplications and artificial joints determinethe factors of postoperative infectiouscomplications. Calculate the treatment ofinfectious complications.Results: Since 2008, done a total1200 with an artificial joint replacementsurgery. Each year, a surgical number isincreasing. 82% of all cases were kneeartificial joint replacement surgery and18% were hip artificial joint replacementsurgery. There are 20 cases of postoperativeinfectious complications.Most suppurativecomplications (14 cases, 70%) are earlycomplications, that directly related to thesurgery and hospital infections are likelyto be. Pathogenic bacterial samples weredetected 10 cases. An assay blanks dependon laboratory capacity and the number ofsamples. Open surgery is 83,3% effective,when early infectious period. No mortalitydue to infectious complications in our center.Conclusion: The main reason of thepostoperative infectious complications ofartificial joint surgery is S. Aureus (99%).14 cases (70%) of all postoperativecomplications are early complications, thatdirectly related to the surgery and hospitalinfections are likely to be. The main factorsaffecting disinfection of the surgical roomand trauma.

Background: One of the confronted problems of doctors and medical personnels is sexually transmitted disease has not been decreased in our country up to now. By last 5 years propagation of trichomoniasis was 16.7-9.5% per 10000 population and infected T.vaginalis. In the practice of parasitology of our country metilen is revealed by gram method hasn’t been introduced which is used in up to date histological analyse. This became the background of our research work. Aim of our research is to diagnose trichomoniasis which infects sexually by cytological analyse and to define its specific and sensibility.Materials and Methods: A total 99 smears of 33 females aged 19-39, used cross sectional descriptive method. Finding T.vaginalis on specimens (1) Vaginal wet mount, (2) Gram staining and (3) Pap stain. Result: In our research T.vaginalis leaked out in wet mount smear was 33%, in Gram stain was (21.2%). The sensibility quality of T.vaginalis on Gram stain is 63%, specific quality is 90%, value of kappa coefficient (К=0.58 Р<0.002). In Pap stain T.vaginalis diagnosed 27,2% and sensibility quality of T.vaginalis is 81%, specific quality is 100%, value of kappa coefficient (К=0.87 Р<0.005). In the case when 3 analysis were positive case was 5 or 15.2%, in the case where 2 analysis were positive case was 6 or 18.2%. Conclusions: The Pap stain sensibility quality of T.vaginalis is 81%, specific quality is 100%, value of kappa coefficient (К=0.87 Р<0.005), that shows should be to give effect on diagnosing of sexually transmitted infectious disease.

Background: Hepatocellular carcinoma (HCC) is a primary liver cancer originating from liver cells, classified as a chronic liver disease. This cancer ranks third in the world in terms of mortality rate. The MELD (Model for End-Stage Liver Disease) and Child-Pugh scoring systems are utilized to assess the prognosis of chronic liver diseases. Based on studies suggesting that certain blood test indicators, particularly red cell distribution width (RDW), could be used to predict the prognosis of liver cancer and other cancers, as well as serve as diagnostic markers, this topic was chosen to evaluate the clinical significance of RDW in hepatocellular carcinoma. Aim: The aim is to study some blood test indicators and compare them with the MELD score and Child-Pugh score systems in order to determine the prognosis of chronic liver diseases. Materials and Methods: A retrospective, single-center, cross-sectional study was conducted at Mongolia-Japan Hospital. Among 322 patients diagnosed with HCC, 24 patients were selected for the case group, and 37 patients with liver cirrhosis were included in the control group. Results: According to the research criteria, 61 patients were selected and divided into 3 groups, and statistical analysis was performed. In the detailed blood test, platelet count and WBC count showed statistically significant differences among the 3 groups (p< 0.024). In the biochemical tests, C-reactive protein (CRP) was p< 0.018, total bilirubin p< 0.001, and the mean albumin level p< 0.015, all showing statistically significant differences among the 3 groups. A statistically significant inverse correlation was observed between RDW-CV and the clinical MELD score (r=-0.356). Conclusion Platelet count, RDW, CRP, total bilirubin, and average albumin levels are significantly different across the studied groups. RDW-CV shows a moderate inverse correlation with MELD scores, suggesting its potential as a prognostic marker in chronic liver diseases. Further research with larger sample sizes is recommended to confirm these findings.

BACKGROUND OF STUDY: Not only in developed countries but also in Mongolia it is vital problem to decide how to improve human life’s quality, to make clear the measurement to take, discover human body’s change, aging mechanism and predict from these diseases. The research on herders’ biological aging which is connected to the geography, nature, environment, climate, inhabitant, culture and labor’s specialty hasn’t been done yet. So it causes the basis to write this research. AIMS: Defining the nomadic herder’s biological aging MATERIAL AND METHODOLOGY: All the herders in Gobi-Altai were included in this research. They wereclassified into ages such as 30-39, 40-49, 50-59 and 60-69, and 202 female and 212 male herders were chosen accidentally. The model types of research “Cross-Sectional” method is used for this, the equipment called “Tanita” which is used for measuring body is used for collecting information and also SPSS-22programmis used for producing result. RESULT OF STUDY: 1. 49% of all research participants are male, 51% are female. 2. Herder’s biological aging is 50,4+9,4 and it shows that 6,3 older than calendar ages. 3. Herders’ aging was different for male and female herders. 81,8 percent of the male herders get older very fast whereas 69,4 of female herders get older slowly. CONCLUSION: • Male herder’s aging is 14 years older than womenThe older female and male herders get, the less their difference in their biological age becomes. • The percentage of the herders whose aging is getting fast is 21-26 % older than biological aging of the UB city’s people. • Biological age and sex’s connection (r=0,0001 p=0,00488) between biological age and weight’s index is (r=0,00488, p=0,001) is different and statistical significant.
