[ 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.

0.05).Conclusion There may be no significant difference in sensory block,motor block and prevalence of adverse effects between injection rates of 0.27 mL/s and 0.04 mL/s in spinal anesthesia with 20 mg isobaric ropivacaine.

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 explore a brief regimen to treat and manage asthmatic patients.Methods 122 asthmatic patients(including 12 inpatients) treated and managed at respiratory clinic were followed up for 1～10 years.The data of these patients were collected and analysed Results On the base of asthma education patients were received inhaled glucocorticoid combined with ? 2 agonist and/or theophylline for two to five years Of 122 patients,20(16 4%) patients remised and remained good control without any medication,90(73 8%) patients relapsed within 1 to 2 years after drug withdrawal Conclusions Asthmatic patients must be treated and managed regularly according to GINA It was especially emphasized that inhaled glucocorticoid is the mainstay of ling term threapy Most patients can remise for quite a long time with agreeable quality of life while a few patients can be cured

Objective To investigate the prevalence of depression and its influencing factors in type 2 diabetes mellitus (T2DM)patients with long-term treatment of insulin pumps.Methods A total of 120 T2DM patients receiving long-term insulin pump treatment were enrolled,and 180 T2DM patients who received intensive insulin injection without pump in the same period were enrolled as controls.We assessed the depression in the two groups using Zung’s self rating scale.Results The depression scores of 32 patients with insulin pump were more than 0.50,and the depression prevalence of these patients was 26.67%,which was significantly lower than 48.89% in the control group (P < 0.05 ). The prevalence of moderate or severe depression was 3.33% and 1.67%, respectively,in the insulin pump group,which were considerably lower than the prevalence of 1 5.56% and 9.44%in the control group (P <0.05).Duration of DM and the number of complications might be independent risk factors of depression in DM patients with insulin pump.Conclusion Long-term use of insulin pump may effectively improve depressive state in T2DM patients through its optimal effect on maintaining blood glucose levels.
