Background. Cerebral palsy (CP), which is the most commonly encountered neuromuscular disorder of childhood, causes permanent physical deficits and sometimes intellectual deficits. Despite advances in the diagnosis and treatment of CP, the incidence of that disorder has not declined; it parallels the increased survival rates of premature infants. The children with CP may not have trunk control because they have spasticity and weakness in their trunk control. Goal. This study aimed to investigate the efficiency of functional electrical stimulation (FES) application on the abdomen-posterior back muscles in children with Cerebral palsy (CP).
Materials and Methods. However 40 children with spastic CP, being treated in physical therapy, were selected by the way of random-sampling in the study, some of children were excluded by exclusion criteria and then 30 children have completed the study. The participants were randomly divided into two groups FES (n=15) and control groups (n=15). The control group received physical therapy 3 days a week in 45 minute for 6 weeks. The children in the FES group received physical therapy in addition to function electrical stimulation. FES was applied 5 days a week for 6 weeks to abdomen-posterior back muscles in 30 minute-long sessions. To evaluate the score of gross motor function measurement (GMFM) and to evaluate the trunk asymmetry in sitting, radiographic measurements were used.
Result. The comparisons of the measurements of the two groups before and after the treatment showed that the GMFM standing score were statistical significantly (p<0.001) increased, and Cobb angles were decreased both groups, but the decrease in the control group was not statistically significant (p=0.128), and FES group was statistically significant (p=0.033). The comparison between groups GMFM standing score increased higher in the FES group than in the control group. Cobb angles after the treatment were statistically significant higher in the FES group than in the control group.
Conclusion: To improve gross motor developing for children with CP, FES applied on abdomenposterior back muscles along with physical therapy is more effective than physical therapy alone.

BACKGROUND
The role of epacl, an exchange protein activated by cAMP. in melanoma migration is largely unknown. Heparan sulfate (HS), a major ECM, and syndecan2, a HS-binding protein on the cell surface, play important roles in regulating such migration. Synde- can2, when activated, translocates to lipid-rich plasma microdomains, known as lipid rafts. We thus examined the role of epacl in HS production and syndecan2 transloca¬tion in melanoma migration.
METHODS
SK-MF.L-2, a human melanoma cell line, and migration assays with Boyden cham¬bers were employed.
RESULTS
Activation of Epacl adenoviral Epacl overexprcssiotl or HpMeOPT, at) Epac-specif- ic cAMP analog, significantly increased cell migration in a time- and dose-dependent manner. Epacl also increased HS production by 2-fold, and the removal of HS abol¬ished Epacl-induced migration. Epacl also increased expression of N-deacetylase/N- sulfotransferase-1 (NDST-1), a key synthetic enzyme for HS. Sucrose gradient frac¬tionation showed that Epacl increased syndecan2 translocation to rafts. In addition, disruption of rafts with lipid depletion abolished Epacl-induced migration.
SUMMARY
Epacl increased migration in malignant melanoma through HS production and syn- decan2 translocation to rafts.

Purpose:
Due to the shortage in the healthcare workforce, insufficient qualifications, a lack of infrastructure and limited resources in Mongolia, it is not always possible for healthcare workers in rural areas who wish to attend continuous training and retraining courses to do so. However, in order to provide high-quality care, the demand for distance learning and the upgrading of knowledge and practice of many medical topics (especially related to morbidity and mortality) are necessary for the rural population. This study aimed to assess the needs of e-learning medical education, of graduates in Mongolia.
Methods:
A cross-sectional research design was implemented. We collected data from 1,221 healthcare professionals (nursing professionals, physicians, midwives, and feldshers) who were randomly selected from 69 government hospitals in Mongolia. Data were collected using self-assessment questionnaires which captured the needs assessment in a survey for online continuous medical education in Mongolia. Data were analyzed using descriptive statistics and Kruskal-Wallis statistical test.
Results:
Ninety percent of the respondents reported that they plan on attending online continuous medical education with the most preferred specialty area being emergency medicine. Results using the Kruskal-Wallis statistical technique suggested the preferred specialty area, educational content, appropriate time schedule, available devices, and tools were statistically significant and were different between the nursing professionals, physicians, midwives, and feldshers (p<0.05).
Conclusion
Findings provide important evidence for the implementation of measures and strategies which can assist healthcare professionals in low and middle-income areas/countries to constructively address their need for enhanced knowledge and practice through distance learning.

Background and Aims:
Hepatocellular carcinoma (HCC) is a common cause of cancer related death
in Mongolia. Early diagnosis is the very important management to increase successful treatment
and survival rate. Glypican-3 (GPC3) protein is highly expressed in hepatocellular carcinoma (HCC)
tissue and in serum of HCC patients. Recent studies have been conducted and suggested as a
diagnostic biomarker for detecting HCC in the early stage. Therefore, we investigated the diagnostic
value of the serum GPC3 level and compared it to the alpha-fetoprotein (AFP) level as a diagnostic
biomarker of HCC.
Methods:
We enrolled a total of 90 participants and divided into 3 groups with HCC (30), with liver
cirrhosis (LC/30) and healthy (30) as the control group (30). GPC3 and AFP serum (sGPC-3, sAFP)
levels were measured using commercially available enzyme-linked immunosorbent assay kits. The
diagnostic accuracy was analyzed using the receiver operating characteristics (ROC) curve and
estimated sensitivity and specificity of each biomarker.
Results:
sGPC3 was significantly elevated in the HCC group as compared to liver cirrhosis and
healthy subjects (658±138.2 pg/ml, 378±25.5 pg/ml, 356.3±29 pg/ml) respectively. sGPC-3 sensitivity
was 96.6% and specificity was 100%. The area under the ROC curve (AUC) for GPC3 was 0.999
(0.996- 1.0).
In comparison, the mean of AFP was significantly higher in HCC (16.9±11.7 ng/ml) than in LC (6.7±7.6
ng/ml) and in healthy subject (3.3±2.1 ng/ml) and AFP sensitivity was 43,3 %, specificity was 95 %
with an AUC of 0.808 (0.696- 0.921).
The combination of GPC-3 with AFP achieved the highest sensitivity (97.1%) and specificity (97%).
Conclusion
Serum GPC3 has a higher sensitivity than AFP for the early diagnosis of HCC.
Combination of two markers showed greatest diagnostic accuracy.
