3.Research advance of PDSS2 gene on carcinoma
Chinese Journal of Pathophysiology 2016;32(9):1713-1717
[ ABSTRACT] Prenyl diphosphate synthase subunit 2 ( PDSS2), which encodes the second subunit of prenyl diphosphate synthase, an essential enzyme involved in the biosynthesis of coenzyme Q10 (CoQ10), is almost expressed in all tissues and organs at different developmental stages of human beings.The abnormal expression of PDSS2 may result in many diseases through impacting the biosynthesis of CoQ10.Recent studies show that PDSS2 gene has decreased in mela-noma, gastric cancer, lung cancer and hepatocellular carcinoma, and the degree of reduced level is closely related to the clinical features, which enlighten us that PDSS2 maybe a tumor suppressor gene involves in the development and progres-sion of carcinoma.This review aims to introduce the recent research progress about PDSS2 gene on carcinoma, discuss its roles and value on cancer research.

The concentration of 5 nucleosides, uracil, uridine, guanidine, adenine and adenosine in culture of Paecilomyces hepialid was determined by the developed method of HPLC. The HPLC method was performed on a Waters SunFire C18 (4.6 mm x 250 mm, 5 μm) column with methanol-water gradient elution as the mobile phase. The detection wavelength was 260 nm and the colunmn temperature was controlled at 30 °C. The linear range was 10.00-200.00 mg · L(-1) (r = 0.9994) for uracil, 10.10-202.00 mg · L(-1) (r = 0.9992) for uridine, 10.00-200.00 mg · L(-1) (r = 0.9991) for guanidine, 10.30-206.00 mg · L(-1) (r = 0.9992) for adenine and 10.45-209.00 mg · L(-1) (r = 0.9991) for adenosine, respectively. The RSD of precision was 0.032%, 0.035%, 0.039%, 0.049%, 0.00080%, respectively. The average recoveries of uracil, guanidine, adenine, and adenosine were 97.34%, 99.10%, 101.6%, 98.61% and 100.2% with RSD of 1.3%, 2.1%, 0.96%, 0.95%, and 1.3% respectively. The method showed high sensitivity, good selectivity, linearity and repeatability, which was suitable for the content analysis of 5 nucleosides components in P. hepialid and its extracts.

OBJECTIVE:
To study the application of isokinetic muscle testing in identification of the faked paralysis to provide scientific data for establishing a standard system of muscle strength in forensic medicine identification.
METHODS:
Fifty-seven patients with bone fracture or nerve damage as damaged group and 128 normal subjects pretended paralysis as faked paralyzed group were included in this study. Isokinetic muscle testing was performed on bilateral knees of all subjects in the two groups. The peak torque (PT) and peak torque angle (PTA) were compared between both sides in each group. The features of torque-time graph of two groups were classified.
RESULTS:
In the damaged group, the differences of PT between two sides of flexors and extensors were statistically significant (P<0.05), while the dif- ferences of PTA were not statistically significant (P>0.05). In faked paralyzed group, the differences of PT and PTA between two sides of flexors and extensors were both statistically significant (P<0.05). The torque-time graph of damaged knee presented mostly as single lead peak, while torque-time graph of the faked paralyzed knee presented mostly as multiple peaks.
CONCLUSION
The feature of torque-time graph could be useful to identify the faked paralyzed extremities in forensic authentication.

Objective:To evaluate the clinical performance of low-count platelet(PLT) samples for Mindray BC-6800 automatic hematology analyzer and compare the detection results between two sampling mode(automatic injection, manual injection).Methods: To evaluate the repeatability and contamination rate of low-count platelet samples depend on ICHC, CLSI and other standards; to choose 108 blood samples with thrombocytopenia and detect them in two kinds of detection mode (automatic and manual operation), and then evaluate the consistency of low-count PLT samples between the two modes.Results: The results of two detection modes for low-count platelet samples showed there were well repeatability between them. The CV% of those samples which PLT were upon 20×109/L can be assurance within 5% in two modes. The value and fluctuation of SD and range of those samples which PLT were under 20×109/L were smaller; the SD of two modes were 0.5 and 0.8, respectively; and the Range were 1 and 2, respectively. Both of the two modes were less than 1% in carryover rates, high PLT accounts has no influence on low accounts. The correlation coefficient was up to 0.9910 between the two modes by analyzing the 108 blood samples. The results demonstrate there were low deviation and well consistency between the two modes by analyzing medical decision level concentration point for them.Conclusion: Mindray BC-6800 has good clinical performance to detect low-count PLT samples and there are well consistency between automatic and manual operation. Clinical Laboratory chooses which suitable mode to detect samples may depend on self-situation.

Objective:To establish the industry standard for growth hormone quantitative labelling immunoassay kit, and to validate it by chemiluminescence labeling and time-resolved fluorescence labeling method which are suitable for the standard.Methods: Different assay method kits, including magnetic particle chemiluminescent assay, electrochemiluminescence assay, chemiluminescence assay and time-resolved fluorescent assay, were used to verified the blank limitation, linearity, accuracy, precision, specificity and stability in accordance with protocol industry standard.Results: Other verification results could meet requirements of the protocol industry standard besides accuracy in part of kits couldn't achieve to anticipative remand (relative deviation couldn't be more than ±10%).Conclusion: According to the verification results, the accuracy requirements was adjusted to ±15%. The other items of industry standard were maintained. The industry standard for growth hormone quantitative labeling immunoassay kit is ultimately established. The standard would contribute to unity quality standard of growth hormone quantitative labeling immunoassay kit, and provide the basis for the supervision and administration of its production, examination, circulation, clinical application and other areas.
