To examine the effects of heterologous expression of ZrGPD1 (encoding glycerol 3-phosphate dehydrogenase ) cloned from osmotolerant yeast Zygosacharomyces rouxii on glycerol production in wild Pichia farinosa,the URA3 gene was amplified from P. farinosa as the homology integrative region. A recombinant plasmid (pUR-ZG) was constructed then transformed into P. farinosa by electroporation. The transformant pfa-gu was obtained by the selectable marker Zeocin TM . Primary results showed that the biomass of pfa-gu was higher than the wild type in the flask and after 72h fermentation the concentration of glycerol of pfa-gu was 37g/L enhanced 30% in comparison with the wild type. It is concluded that heterologous expression of ZrGPD1 is useful for increasing glycerol production and the ability of osmoregulation in P. farinosa.

Objective To establish a specific fluorescence quantitative method for determining the mRNA expression of Toll-like receptor3(TLR3)in peripheral blood mononuclear cells(PBMCs).Methods Using the Beacon Designer 2.1 software,specific primers and Taqman-MGB probe were designed.The plasmid pMD18-T-TLR3 was constructed as calibrator and the amplified fragment was obtained by reverse- transcript-PCR(RT-PCR).RNA quantification based on cycle threshold values(Ct)was used to establish the standard curve.According to which,the TLR3 mRNA levels in 30 normal individuals,20 patients with primary biliary cirrhosis(PBC)and 20 ones with chronic liver cirrhosis induced by HBV were calculated automatically by software after the fluorescence of PCR product was detected continuously during amplification.Results The linear detection range of the assay for TLR3 gene and ?-actin was 10~2-10~8(r= -0.9974)and 10~3～10~8(r=-0.9984),respectively.The coefficient of variation of both intra-and inter- assay reproducibility for high concentration sample were 6.7% and 8.7%,respectively,and those for low concentration sample were 12.3% and 14.0%.The TLR3 mRNA expression level ranges from 3.46?10~2- 4.51?10~3 copies/?g RNA,4.92?10~2-1.42?10~4 copies/?g RNA and 2.58?10~2-7.17?10~3 copies/?g RNA for 30 healthy individuals,20 PBC patients and 20 ones with chronic liver cirrhosis induced by HBV, respectively.Conclusion We have successfully set up a FQ-RT-PCR method for detecting TLR3 mRNA, which may be used as an excellent tool for the clinic and basic study on the expression of TLR3 gene.

Objective To observe the effect of atorvastatin on mixed dyslipidemia in type 2 diabetic patients. Methods 39 patients of type 2 diabetic with mixed dyslipidemia were taken with atorvastatin for 6 months,and the change of total cholesterel(TC),triglyceride(TG),low-debsity-lipoprotein-cholesteral(LDL-C),high-debsity-lipopro- tein-cholesteral(HDL-C)were observed.The incidence of side-effect was recorded.Results TC,TG,LDL-C were obviously reduced and their extent of reduction were 26.17 %,54.97 %,38.92 %.HDL-C was obviously increased and it's extent of increase was 14.81%(P

Adult male Kunming mice were divided into normal control group,propylthiouracil(PTU) treated group and PTU+T_4 treated group.Neurogranin(Ng)protein expression in the hippocampus after 8 weeks was assayed by Western blotting and immunohistochemical method.Results showed that Ng protein was decreased in the hippocampus of male mice with adult-onset hypothyroidism,suggesting that decreased Ng,which is correctable by T_4,is involved in cognitive dysfunction in adult-onset hypothyroid male mice.

Objective To evaluate the value of 3.0T susceptibility-weighted magnetic resonance imaging (SWI) in the diagnosis of cerebrovascular malformations. Methods Forty-six patients with cerebrovascular malformations, admitted to our hospital fiom May 2008 to December 2010, were examined with a 3.0T MR scanner. All patients were examined with MRI conventional sequences T1WI,T2WI, 3DTOF, and their results were compared with SWI sequence so as to evaluate the value of SWI in the diagnosis of cerebrovascular malformations.Results Twenty-five patients had arteriovenous malformation (AVM), 10 with cavernous hemangioma, 8 with venous malformations, and 3 with telangiectasis in the 46 patients with cerebrovascular malformations. SWI could delineate all the cerebrovascular malformation lesions, especially small lesions, but could not display all supplying artery in AVM. 3DTOF was a better technique in delineating large AVM lesions. Conclusion SWI is much more sensitive in showing small cerebrovascular malformations; and combined with other MR sequences,clear diagnosis of cerebral vascular malformations can be made by SWI.

Objective To evaluate the cardiopulmonary exercise capacity in patients with essential hypertension (EH) complicating with or without left ventricular hypertrophy (LVH). Methods Graded maximal exercise test on the bicycle ergometer with respiratory gas analysis were performed in 30 gender and age matched normotensive controls, 40 EH patients without LVH and 30 EH patients with LVH (LVMI 125 g/m2 in males and 120 g/m2 in females). Metabolic equivalents (METs), oxygen uptake(VO2), oxygen uptake to body mass ratio (VO2/kg) and oxygen uptake to heart beat ratio (VO2/HR) at time of reaching anaerobic threshold (AT) and at maximal oxygen uptake (VO2max) were measured and compared. Results METs and VO2/kg were significantly reduced in EH patients with or without LVH compared with controls [ at AT, METs: 3.57±0. 8 and 4. 34±1.47 vs. 5.21±1.45 ; VO2/kg: 12. 38± 2. 85 and 14. 42±4. 33 vs. 18.48±4. 52, all P < 0. 01 ;at VO2max, METs:4.94±1.24 and 5. 90±1.51 vs. 6.96±1.85;VO2/kg:(17.20±4.34) ml·min-1·kg-1and (20.41±4.59 )ml · min-1·kg-1 vs. (24. 04±5.21) ml·min-1·kg-1, all P < 0. 01 ]. METs and VO2/kg at both time points were also significantly reduced in EH patients with LVH compared EH patients without LVH ( all P < 0. 05). The lower VO2/kg in hypertensive patients was significantly correlated to higher LVMI ( P < 0. 05 ). Conclusions Cardiopulmonary exercise capacity was reduced in hypertensive patients, especially in hypertensive patients with LVH.

OBJECTIVETo observe the effect of Yiqi Huoxue Qingre Huashi Recipe (YHQHR, a recipe capable of supplementing qi, activating blood, clearing heat, and dissipating dampness) on ulcer healing and Helicobacter pylori (Hp) eradication rate in Hp positive peptic ulcer patients, and to explore coccoid Hp occurrence in the eradication.

METHODSTotally 80 Hp positive peptic ulcer patients were assigned to the treatment group and the control groups by random digit table, 40 in each group. All patients received standard triple therapy of Western medicine for 2 successive weeks. Those in the control group additionally took omeprazole enteric coated tablet, 20 mg each time, once per day for 4 successive weeks. Those in the treatment group additionally took YHQHR, twice per day for 6 successive weeks. The ulcer healing was observed and recorded by gastroscope after discontinued medication of 14 days. The effective rate of ulcer healing under endoscope was statistically calculated. Rapid urease test (RUT) was performed in one small piece of tissue from corpora ventriculi and sinuses ventriculi using 14C breathe test (UBT). Gastric juice was collected from the stomach. Hp urease gene amplification test (urea A-PCR) was performed in living tissue from gastric antrum. Results obtained from the above three test methods were recorded and assessed to decide the final eradiation rate. Gastric mucosa tissue was observed under electron microscope,attempting to find non-eradicated Hp, which was further observed.

RESULTSThe total curative effect under gastroscope was 97.5% (39/40 cases) in the treatment group, obviously higher than that in the control group (80.0%, 32/40 cases) (P < 0.05). The eradication rate of Hp was 75.0% (30/40 cases), obviously better than that of the control group (52.5%, 21/40 cases) (P < 0.05). The total positive Hp numbers after treatment was 14C UBT (12), RUT (8), and urea A-PCR (27), respectively. The Hp positive rate detected by 14C UBT and RUT was lower than the Hp positive rate detected by urea A-PCR (P < 0.05). Rod-like and coccoid Hp bacteria could be observed under electron microscope.

CONCLUSIONYHQHR combined standard triple therapy was more effective than standard triple therapy alone in promoting ulcer healing and elevating the eradication rate of Hp.
