Introduction:There is an increasing trend of obesity in children and adolescent globally. The objectives of this study were to identify the prevalence of overweight and obesity among students from secondary schools and to determine the mean random blood sugar (RBS) for the overweight and obese students.Methods:This was a cross sectional study. Two secondary schools that were scheduled for visit by the School Health Team, Taiping in July 2016 were included. A standardized data collection sheet was used to collect the data. Overweight and obesity were defined based on WHO 2007 reference for BMI-for-age criteria. Random blood glucose was checked for overweight and obese students.Results:A total of 184 school students consented and participated. 128 (69.6%) were female and 90 (48.9%) were Malays. The mean weight and height were 56.21 kg and 1.61 m respectively with BMI of 21.49 kg/m2. Overall, the prevalence of obese and overweight were 12.5% and 10.9% respectively. Among the 4 BMI groups, there were no significant difference found in sex (p=0.849) and races (p=0.536). However, there was significant difference (p=0.042) in mean RBS for obese and overweight students between races. RBS readings among overweight and obese students were within normal range with mean of 5.95 (0.67) mmol/l (range between 4.60 – 7.70 mmol/l).Conclusions:The overall prevalence of overweight and obesity were comparable with other studies done in Malaysia. Nevertheless, there was no prevalence of Type II diabetes mellitus among them.

OBJECTIVETo study the expression of Toll-like receptor 4 (TLR-4) and caspase-3 in the intestine of neonatal rats with necrotizing enterocolitis (NEC), and explore the protective effects and possible regulatory mechanisms of glutamine (Gln) in NEC.
METHODSSixty premature rats were randomly divided into three groups (n=20 each): control, NEC model and Gln intervention group. NEC model was prepared by formula feeding, hypoxia and cold stress. The Gln intervention group was also subjected to hypoxia and cold stress but was fed with formula containing Gln (0.3 g/kg). Two days later, the rats were sacrificed and the intestine tissues were obtained. The histological changes of ileal tissues were observed by hemetoxylin and eosin staining. The expression of caspase-3 and TLR-4 protein in the jejunum, ileum and colon were detected by inmunohistochemistry. The expression of TLR-4 mRNA in the jejunum, ileum and colon were detected by RT-PCR.
RESULTSCompared with the control group, the histological score of ileal tissues, and the expression of caspase-3, TLR-4 protein and TLR-4 mRNA in the NEC model group increased significantly (P<0.01). Gln intervention decreased significantly the histological score of ileal tissues, and the expression of caspase-3, TLR-4 protein and TLR-4 mRNA compared with the NEC model group (P<0.05).
CONCLUSIONSTLR-4 might be involved in the pathogenesis of NEC. Gln may provide protective effects on intestine possibly through reducing the TLR-4 expression and then decreasing the apoptosis of intestinal epithelial cells.

Background: Simvastatin is usually taken in the evening due
to the circadian rhythm of hepatic cholesterol biosynthesis.
The degree of reduction of low-density lipoprotein
cholesterol (LDL-C) and the level of adherence to different
administration time remained unknown in the Malaysian
population. This study aims to investigate the effect of
simvastatin on the percentage changes of lipid profile and
the level of adherence to when simvastatin was instructed to
be taken at different timing.
Methods: Nine primary care health clinics across Malaysia
participated in this study. 147 statin-naive subjects were
selected through convenient sampling and randomised into
one of the three arms (after breakfast, after dinner or before
bedtime). Differences on percentage reduction of LDL-C
from baseline and level of adherence among the three
groups at week-16 were compared. The main outcomes
measured in this study were the percentage change of lipid
parameters and the percentage of high-adherence
(MMAS=8) at week-16.
Results: 59.2% of the patients were male. The mean age of
the study population was 53.93± 10.85 years. Most of the
patients were Malays (69.4%); followed by Indians (22.4%)
and Chinese (8.2%). LDL-C decreased from 4.26 (Standard
Deviation, SD1.01) to 2.36 (SD0.69)mmol/L at week-16 for
patients taking simvastatin before bedtime; an absolute
reduction of 44.95%.The differences of LDL-C percentage
reduction between three arms were significantly different
(p<0.001). The greatest LDL-C reduction was observed when
simvastatin was taken before bedtime and revealed 56.2%
patients with high-adherence at week-16.
Conclusion: Simvastatin showed superior LDL-reduction
and higher level of adherence when being instructed to be
taken before bedtime

OBJECTIVETo determine the clinical results of selected CD34(+) cell autologous transplantation in advanced malignant tumors.
METHODSAfter pretreatment, fifteen patients aged 12 - 70 (49.5) years with various Stage III or IV malignant tumors were given the sorted CD34(+) cells collected by magnetic-activated cell sorting (Clini MACS, Milteny Biotech, Germany).
RESULTSPeripheral blood progenitor cells (PBPC) from the patients were mobilized by chemotherapy and G-CSF 5 micro g/kg per day. CD34(+) cells gave 2.0 - 5 log depletion after cell sorting, with a median yield of CD34(+) selected cells of 2.4 (0.15 - 12.03) x 10(6)/kg. It gave a median recovery of 64 (52 - 81.4)% and median purity of 98.2 (83.2 - 99.7)%. The median time of neutrophil recovery > 1.0 x 10(9)/L and platelet recovery > 20 x 10(9)/L post-transplantation were 14 (8 - 26) days and 13 (11 - 35) days, respectively. On follow-up of 2 - 33 (11) months, the event-free survival rate was 53.3% (8/15) and the overall survival rate was 66.7% (10/15).
CONCLUSIONTransplantation of autologous selected PBPC CD34(+) cells gives prompt and stable engraftment. Selected CD34(+) cell transplantation, being a safe approach, may improve the clinical outcome even in patients with advanced malignant tumors.
