To study the correlation within psychological and social suffering in palliative care cancer patientsWe provide study within 100 palliative care patients with cancer stage 3-4. Depression was evaluated by San Diego hospice screening method with 3 questions. Anxiety was assessed by Spielberg -Hanin anxiety scale. Spiritual pain was assessed by San Diego hospice questionnaire, which includes main 4 factors of spiritual suffering, like cooperation, meaning of life, hope, forgiveness. Results of study was statistically evaluated by SPSS20 program.19% of patients had depression, 40% had anxiety, 46% patients had insomnia. 18% of patients with depression had spiritual suffering. 33% of patients with anxiety had spiritual pain. 31% of patients with insomnia had spiritual pain. Depression and spiritual suffering had mild correlation (R-0.318), anxiety and spiritual suffering had mild correlation (R-0.330), insomnia and spiritual suffering had very strong correlation (R-0.84). Psychological suffering of palliative care cancer patients increased with spiritual suffering and correlated with spiritual suffering. Especially insomnia had very strong correlation with spiritual suffering (R-0.84).

INTRODUCTION:In connection with request and financial assistance of Swiss Development Agency ‘’Mercury exposureand health impact assessment study among small scale miners in mercury free technology, wasconducted by researchers of Toxicology division of NCPH.GOAL:To determine mercury exposure level in biological samples of local small scale miners from mercury freetechnology introduced area. To reveal chronic mercury intoxicated patients,MATERIALS AND METHODS:Totally 147 artisanal miners from 33 cooperatives for small scale mining from Bayan-Îvoo soum ofBayankhongor, Bornuur sum of Tuv, Bayangol, Mandal and Tunkhel sum of Selenge province areparticipated in this study and the study was performed by cross sectional study methods during April toDecember, 2014.Over all 147 participants were in the first part of study, 60.5% out of 147 (89 participants) were in secondparts, and another 35.4% (52 people) were participated to the third parts of study. The participants wereundergone in to toxicological, dermatological and neurological examinations and the WHO guidance formercury exposure determination was followed in this study.RESULTS:On the results of all testing we revealed that there were 2 cases of chronic mercury intoxicated patientsfrom each Bayangol Bornuur soum, 2 from Mandal soum, and 3 from Bayanovoo soum.Overall 7 patientswere diagnosed as chronic mercury intoxicated and it comprised 4.7%of (n=147) all involved participants.We have observed that average height of total medical examination number was (2.9) in Bornuur soum.It indicated that there will have higher number of patients would exist in Bornuur soum than others.Ourstudy result has shown that neurological symptoms like tremor and imbalance were more diagnosedamong participants from Mandal and Bayngol soums. It implies that the health of the small scale minersfrom this soum more affected and needed to be investigating further.CONCLUSIONS:Mercury is still being used among artisanal gold miners even thoughit is still illegal. Further medicalevaluation and assistance needed to be taken for newly diagnosed 7 patients.

Sleep and wakefulness are physiological processes in our lives that are regulated by circadian rhythms. The level of melatonin, the "sleep hormone", increases with the onset of darkness, and its production slows down in the morning. Exposure to artificial light at night disrupts our circadian rhythm and the processes it controls. Shift work is when an individual works from 9 am to 5 pm. But the night shift refers to the time when a group of workers who work at night in factories and enterprises work in the evening or at night, especially from 4 p.m. to 8 a.m. according to a regular schedule. One in five people in industrialized countries work night shifts, and studies in America and Europe show that between 15 and 30% of adult workers have some form of shift work. Between 10% and 30% of shift workers meet the diagnosis of shift work disorder (SWD). 5-10% of shift workers experience severe shift insomnia and sleepiness. At least ¾ of shift workers suffer from insomnia. Excessive sleepiness usually occurs during shifts (mainly at night) and is associated with impaired cognitive ability due to the need for sleep and reduced alertness, and decreased alertness reduces performance. Job performance is influenced by many workplace environmental factors, including workload, coworker relationships, stress levels, and extended hours. A nurse specialist provides nursing care by monitoring and evaluating 24 hours a day, and by working night shifts, the circadian system of sleep is disturbed, causing sleep problems and insomnia. When examining how night shift work affects nurses' ability to concentrate, the decline in concentration (33.3%) was twice as high as that of day shift nurses (16.7%). found that shift nurses who worked the night shift had higher rates of insomnia and chronic fatigue compared to nurses who stopped working the night shift. Lack of sleep manifests as a decline in cognitive functions such as attention, decision making, and reaction time. These cognitive and functional declines can negatively affect quality of life and lead to impaired job performance. An Australian study by Winwood et al found that fatigue associated with night shifts increases the risk of human error and injury, and negatively affects the quality of patient care. Lack of sleep significantly affects nurses' alertness, concentration, and job performance. This review article discusses the relation between shift work-related sleep and job performance based on international research findings.

Purpose: Kidney function assessment method is improving gradually. New biomarkers are studied and started using in clinical practice, such as beta 2 microglobulin. Beta 2 microglobulin is improving diagnostic and prognosis in CKD patients. We aimed to assess convenience usage of B2MG alone and B2MG based eGFR in Mongolian patients. Materials and method: We included 116 patients diagnosed with CKD and 55 donors whom with normal kidney function. We collected participant's blood sample by venipuncture in plain vacutainer. Creatinine, urea, cystatin C, B2MG were tested by Roche Cobas C311 equipment in serum. eGFR was calculated by online calculation from NKF. B2MG based eGFR was calculated by eGFR=133*B2M^-0.852 Result: Assessment of kidney biomarkers and eGFR was significantly correlated in both groups. Measured serum creatinine was 3.37 mg/dl in CKD patients and 0.87 mg/dl in donors. Serum urea was 97.6 mg/dl, 31.1 mg/dl, cystatin C 3.05 mg/L, 1.49mg/L and beta 2 microglobulin 10.65 mg/L, 2.43 mg/L respectively. Estimated GFR was 21.5-28.4 ml/min/1.73m2 in CKD patients and 47.7-103.9 ml/min/1.73m2 in donors. Assessing kidney function by biomarkers (r=0.720-0.918, p<0.05), and eGFR (r=0.495-0.996, p<0.05) were significantly correlated in both groups. Conclusion B2MG can be used in clinical practice in Mongolia. B2MG is optional with creatinine, urea, cystatin C for assessing and improving kidney function.

In this study, we aimed to evaluate kidney function using biomarkers and biomarker based eGFR in kidney donors within 5 years of organ transplantation. Materials and method: 91 donors enrolled in our study. We measured body weight and blood and urine samples for laboratory tests. eGFR was calculated using 6 estimations. Result: The mean serum creatinine in participants was 0.81±0.22 mg/dL, cystatin C was 1.11±0.19 mg/dL, urea was 31.44±8.02 mg/L. Systolic hypertension in subjects was 130.0±16.5 mmHg while diastolic hypertension was 78.4±10.8 mmHg. In all donors, 15.9% (n=14) had hematuria, 23.6% (n=21) had proteinuria, 24.7% (n=19) had albuminuria. Body weight, creatinine, cystatin C and urea measurements had gradually increased over the years. The average eGFR was 72.9±17.9 to 112.8±34.0 ml/min/1.73m² showing 0.15%-35.22% before donation. Follow – up rate was 28.3-59.2% of total donors.Having health insurance and living far from Ulaanbaatar city influenced follow – up rate. Donor registration data should be updated regularly. Conclusion
1. Serum creatinine, cystatin C, urea was increasing in living kidney donors. Hypertension and microalbuminuria was greater than other donor study results.
2. eGFR decreased 0.15-35.22% in donor. CKD EPI combined equation was best for donor.
3. Health insurance and living far from Ulaanbaatar city were the influencing follow – up rate. Registration data is missing in 25.5%-82.4% of total donors suggesting enhancement in data collection.

Research of function of vitamin D on immune system has been studying since the study revealed that vitamin D receptor is expressed on the surface of the immune cells. 1,2-dihydroxyvitamin D3 [1,25(OH)2D], physiologically active form, can be generated through hydroxylation of 25-hydroxyvitamin D3 [25(OH)D], inactive form of vitamin D, in a liver, connecting with specific VDR make biological action. Vitamin D make different biological actions depends on connecting with different immunological cells. Some studies indicated that Vitamin D plays pivotal role in antibacterial innate immune responses through regulating reaction of the main cells as macrophages and dendritic cells. Moreover, calcitriol, the active form of vitamin D, is connected with VDRE, modulates the innate immune response through directly inducing expression of catelicithin and β-defensin as antimicrobial peptides, reducing secretion of IL-1b, IL-6, TNF-a, RANKL, COX-2 as proinflammatory cytokines and increasing production of IL-10, an anti-inflammatory cytokine. Vitamin D plays in proliferation and differentiation of T and B cells and regulates the activities of over 500 genes. Vitamin D differently impacts on per se stages of T cells’ proliferation. Vitamin D indirectly mitigates the differentiation from immature B cells to plasma B cells while it directly impacts on regulation of overloaded production of antibodies in plasma B cells. In conclusion, vitamin D modulates the innate- and adaptive immune response through regulation on activation of APCells, proliferation and differentiation of immune cells, secretion of some antibacterial peptides.

Introduction: When human body encounters external pathogens primary/innate immunity cells are activated by recognizing them and secondary/adaptive immunity is activated consecutively. Immune cell surface receptors, called Toll-like receptors (TLRs) recognize and bind pathogens. In our previous study, we revealed that there is a synergistic action between TLR9 and IFN-γ signaling in the endothelial cells. Purpose: To determine the role of negative and positive regulatory proteins on the IFN-γ/TLR9 synergistic signaling pathway Materials and Methods: This study was held in the Core Laboratory, Science Technology Center, Mongolian National University of Medical Sciences (MNUMS). In this study, murine endothelial cell (END-D) culture was used. The negative and positive regulator protein expression was detected by Western blotting. Result: Result of immunoblotting assay indicated that CpG DNA enhanced IFN-γ positive regulator protein p38 phosphorylation in the endothelial cells. Treatment by TLR9 ligand CpG DNA and IFN-γ increased p38 activation in 0.5 hour and 1 hour. CpG DNA inhibited IFN-γ negative regulator SOCS1 protein expression in 4 hr and 8 hr. Therefore, TLR9 ligand CpG DNA increased IFN-γ signal transduction in the endothelial cell line. Conclusion TLR9 ligand CpG DNA has decreased IFN-γ negative regulator protein SOCS1 expression. CpG DNA has increased IFN-γ positive regulator protein p38 phosphorylation.

Introduction: Toll like receptors (TLRs) are a class of proteins that key role in the innate immune system. The SOCS1 and SHP2 proteins are negative-feed loop inhibitors of signaling of JAK/STAT and TLRs pathways. Purpose: To determine negative regulator protein activation which is activated through TLR7 ligand/IFN-γ signal transduction in endothelial cells. Methods: We used mouse aortic linear endothelial cell (END-D); protein expressio was detected by western blotting Results: We analyzed a time dependent stimulation effects of negative regulator proteins stimulated by TLR7 ligand/IFN-γ in endothelial cell cultures. Imiquimod of 10 μg/ml treatment of 1 hr was followed by 100 ng/ml IFN-γ stimulation for 1-8hr to analysis of negative regulator SOCS1 and SHP2 protein expression.
In untreated cells, there was low activations of negative regulator SOCS1 and SHP2 proteins. IFN-γ stimulation alone had increased SOCS1 and SHP2 protein expressions, also imiquimod treatment highly elevated SOCS1 and SHP2 expressions. However imiquimod and IFN-γ doubled treatment have decreased activation of negative regulator SOCS1 and SHP2 proteins. These findings suggest SOCS1 and SHP2 proteins are inhibitors in the TLR7 ligand/IFN-γ signaling. Conclusion Negative regulators, SOCS1 and SHP2 strongly suppressed activations of TLR7 ligand/IFN-γ signaling

Introduction: Air pollution has become one of the major problems in socio-economic and health issues in Mongolia. Among the various hazards of particulate matter (PM) pollutants, microorganisms in PM2.5 and PM10 are thought to be responsible for various allergies and for the spread of respiratory diseases. Recent studies have shown that PM2.5 particles can cause chronic heart failure, heart arrhythmias, and strokes, as well as lung damage, cirrhosis, inflammation, cancer, cardiovascular disease, and metabolic disorders. Furthermore, some studies have concluded that PM2.5 particles in the environment are a risk factor for gastrointestinal, liver, colon, and lung cancer as well as it affects the growth and metastasis of various cancer cells caused by other factors. In our country, the health effects of air pollution and the relationship between the pathogenesis of cancer research are scarce. Therefore, the study of the effects of PM2.5 particles on cancer cell proliferation, migration (metastasis) can provide a significant role for cancer treatment, diagnosis, and prevention. Purpose: Determining the effects of PM2.5 particles on cancer cell proliferation, migration (metastasis) in in-vitro Material and Methods: A human liver cancer cell line (HepG2), human gastric cancer cell line (AGS) were obtained from the central scientific research laboratory in the Institute of medical sciences. HepG2, AGS cells were seeded at a concentration of 1*105 cells/mL in a culture flask and cultured in RPMI-1640 medium supplemented with 10% FBS, 1% antibiotic mix (penicillin, streptomycin) in a humidified atmosphere of 5% CO2 at 37 °C. The cytotoxic effect of PM 2.5 in AGS, HepG2 cells were evaluated by MTT, CCK8 assays. AGS, HepG2 cells were incubated in 96 well plates for 24h then treated with different concentrations (0, 5, 10, 25, 50 and 100 μg ) of Bayankhoshuu, Buhiin urguu, and Zaisan samples for 24h, respectively. Results: Concentrations of 10, 25, and 50 μg/ml of samples collected from the Bukhiin urguu and Zaisan in March increased HepG2 cell growth, while doses of 25, 50 μg/ml of samples collected from Bayankhoshuu in March and December increased HepG2 cell growth. Therefore, concentrations of 25 and 50 μg/ml of samples collected from Bayankhoshuu in March increased AGS cell growth, while concentrations of 25, 100 and μg/ml of samples collected in December increased AGS cell growth. However, no cytotoxic effect was observed in the sample collected from Zaisan in March, whereas the PM2.5 sample enhanced AGS cell growth in dose dependent manner in December.(p <0.05) Conclusion High levels of heavy metals were detected in samples collected in December from Bayankhoshuu, Bukhiin urguu and Zaisan of Ulaanbaatar. Concentration of 25 μg/ml of samples collected from the Bukhiin urguu and Zaisan in March increased HepG2 cell growth. Concentrations of 25 μg/ml of PM2.5 collected from three regions around Ulaanbaatar increased HepG2 and AGS cell migration.
