Background: Data from the National Health and Morbidity Survey 2011 showed that 20.8% of
Malaysians above 30 years have diabetes. 10.1%of them are undiagnosed. Mobile blood drives could
complement the public health department efforts in diabetes screening for early detection of the
illness. Aims: This study aims to determine the necessity of diabetes screening as a routine screening
program during blood donation campaign. Methods and Material: Blood donation campaigns which
involved the public community between January 2013 and June 2013 were included in this study.
Donors above 30-years-old, not known to have diabetes, consented for diabetes screening. Diabetes
screening was done by checking random capillary blood sugar (RCBS) levels while performing a
Hemoglobin test and ABO grouping. Donors with RCBS of ≥7.8 mmol/L were given appointments
for oral glucose tolerance test (OGTT) to confirm the diagnosis of diabetes. Results: A total of 211
diabetes screenings were performed. Mean RCBS was 6mmol/L. 43(20.4%) donors had RCBS≥
7.8mmol/L. 10 donors were later diagnosed to have diabetes (5.0%) and 5 donors were prediabetes
(2.5%). 9 donors (4.3%) did not turn up for further investigation. Conclusions: Blood donors are
expected to be healthy volunteers. The diabetes prevalence among blood donors (5.0%) is considered
low if compared with the prevalence in the whole population (20.8%). However, the number is largely
comparable to the prevalence of undiagnosed diabetes in the country (10.1%). Routine diabetes
screening during blood donation campaign should be implemented to safeguard donors’ health and
serve as a public health initiative to improve community health.

A reasonable method for the quality control of tablets of Ginkgo biloba leaves was established in this paper. The total flavonol glycosides and terpene lactones of G. biloba tablets were quantified by HPLC. Totally, 16 batches of the commercially available tablets of G. biloba leaves were determined. Among of them, 2 batches were unqualified in the content of total flavonol glycosides, and 3 batches were unqualified in the content of terpene lactones. A validated HPLC fingerprint method was established to evaluate the commercially available tablets of G. biloba leaves with the assistance of LC-MS. Sixteen batches showed the similarity of 0.763-0.989. There were 31 fingerprint chromatogram peaks were identified as flavonoids compositions by LC-MS. This provides a research idea for the quality control of tablets of G. biloba leaves.

OBJECTIVETo explore the effect of Shugan Jianpi Recipe (SJR) on LXRα/FAS signaling pathway mediated hepatocyte fatty deposits in nonalcoholic fatty liver disease (NAFLD) rats.
METHODSTotally 75 SPF grade male SD rats were randomly divided into 5 groups, i.e., the normal control group, the model group, the Shugan Recipe (SR) treatment groups, the Jianpi Recipe (JR) treatment group, and the SJR group. Except rats in the normal control group, the NAFLD rat model was duplicated using high fat diet (HFD). SR (Chaihu Shugan Powder) was administered to rats in the SR group. JR (Shenlin Baizhu Powder) was administered to rats in the JR group. SJR (Chaihu Shugan Powder plus Shenlin Baizhu Powder) was administered to rats in the SJR group. Changes of liver fat were analyzed using automatic biochemical analyzer. Liver cells were separated by low-speed centrifugation. Their activities and purities were identify using Typan blue and flow cytometry (FCM). Expression levels of LXRα and FAS mRNA in hepatocytes detected by Real-time quantitative PCR. Expression levels of LXRα and FAS protein were detected by Western blot.
RESULTS(1) Pathological results showed in the model group, hepatocytes were swollen with nucleus locating at the cell edge after oil red O staining; unequal sized small vacuoles could be seen inside cytoplasm. Some small vacuoles merged big vacuoles. All these indi- cated a NAFLD rat model was successfully established by high fat diet. Pathological structural changes could be impaired to some degree in all medicated groups, especially in the SR group. (2) Compared with the normal control group, expression levels of LXRα and FAS genes and proteins obviously increased in the model group (P < 0.01). Compared with the model group, their expression levels were obviously down-regulated in the JR group and the SR group (P < 0.01, P < 0.05).
CONCLUSIONSLXRα/FAS signaling pathway was an important signaling pathway for mediating lipid metabolism disorders of NAFLD rats. SJR could make hepatocyte fatty deposits tend to repair by adjusting the LXRα/FAS signaling pathway in NAFLD rats, which might be one of important mechanisms for SJR to prevent and cure NAFLD.

A new ultrasonic-assisted extraction (UANE) method coupled with solid phase extraction (SPE) using ultrasonic fountain was established for the extraction of eight common ginsenosides from leaves of Panax quinquefolium L. The extraction system has been designed and several experimental parameters,including the type and volume of extraction solvent,pH value and salt concentration of extraction solvent,type and volume of elution solvent,and amount of C18, extraction time were examined and optimized. Under the optimal conditions,the recoveries of ginsenosides were in the range of 96. 3% -110. 6%, the relative standard deviations (RSDs) were in the range of 2.8%-4.3%,indicating that the method has a good performance for the extraction of these ginsenosides. Compared with traditional UANE-SPE method, the modified method simplified the extraction device,shortened the extraction time and improved the extraction efficiency.
