Stroke is one of the most important causes of disability throughout the world.Epide- miological and clinical studies have demonstrated that statins significantly decrease the incidence of ischemic stroke.In addition to lipid-lowering effect,statins may also have a number of other acting mechanisms that are not dependent on reducing cholesterol levels.Moreover,statins inhibit cerebral vasospasm caused by subarachnoid hemorrhage.For most of the individuals,the safety and tolerability of statins are well.

Objective To discuss the quantitative diagnosis of stagnation of Qi and blood stasis syndrome in chronic prostatitis. To make diagnosis chart and ensure diagnosis threshold level which provide statistics evidence for syndrome differentiation of TCM. Methods By the statistical ways, 168 cases of chronic prostatitis belong to stagnation of Qi blood and stasis syndrome and 198 cases of non-stagnation of Qi and blood stasis syndrome were investigated. To make a diagnosis chart and ensure diagnosis threshold level by applying the method of the maximum likelihood discriminatory analysis. Results The quantitative diagnosis chart was made and diagnosis threshold level was 26. According to the retrospective and prospective test, its sensitivity, especially degree, coincidence rate, error rate and positive likelihood ratio were 94.64%, 88.89%, 91.53%, 8.47%, 8.52 and 94.28%, 90.32%, 92.42%, 7.58%, 9.74. Conclusion The indexes of the quantitative diagnosis have good objectivity. According to the retrospective and prospective test, the diagnosis chart was proved to be practical.

Objective:To investigate the characteristics and significance of insulin-like growth factor 1(IGF- 1) and insulin-like growth factor binding protein 2 (IGFBP2) expressions in ankle cartilage of patients with Kashin-Beck disease (KBD).Methods:In this case-control study, 10 KBD patients who were hospitalized in the Department of Orthopedics of Shaanxi Provincial People's Hospital from January 2010 to December 2016 were selected as KBD group, and 10 patients with ankle fracture caused by trauma but without talus injury during the same period were selected as control group, the cartilage tissues of the two groups were collected. IGF-1, IGFBP2 positive cells, the mRNA and protein expressions of IGF-1, IGFBP2 in the cartilage tissues were detected by immunohistochemistry, real-time fluorescent quantitative PCR and Western blotting, respectively. According to the expressions of IGF-1 and IGFBP2 in ankle cartilage of KBD patients, a patient with amputation caused by trauma was selected in Shaanxi Provincial People's Hospital, and ankle joint cartilage was taken to prepare chondrocytes for in vitro cell verification experiments. The chondrocyte were divided into control group (0 ng/ml T-2 toxin), T-2 treatment group (20 ng/ml T-2 toxin) and T-2+ IGFBP2 silenced group (20 ng/ml T-2 toxin+ 50 nmol/L IGFBP2 siRNA), the MTT method and dimethyl methylene blue staining were used to detect the activity of chondrocyte and the secretion of sulfated glycosaminoglycan (sGAG). Results:In the control group and the KBD group, the number of IGF-1[(47.26 ± 8.97), (68.15 ± 7.42) cells] and IGFBP2 positive cells [(27.56 ± 5.40), (71.85 ± 7.62) cells] in the cartilage tissues were significantly different ( t = 4.487, 9.402, P < 0.01). Compared with the control group, the IGF-1, IGFBP2 mRNA and protein expression levels in KBD group were significantly higher, the differences were significantly different ( t = 3.340, 20.700, 4.684, 8.699, P < 0.05 or < 0.01). In cell experiment, the chondrocyte activitives and sGAG contents of the control group, T-2 treatment group, and T-2+ IGFBP2 silenced group were significantly different ( F = 226.70, 80.66, P < 0.01); among them, the cell activitives and sGAG contents of the T-2 treatment group and T-2+ IGFBP2 silenced group were lower than those of control group ( P < 0.05), and the T-2+ IGFBP2 silenced group were higher than those of the T-2 treatment group ( P < 0.05). Conclusions:The expressions of IGF-1 and IGFBP2 in the ankle cartilage of KBD patients are significantly higher. Silencing IGFBP2 gene can reduce the inhibitory effect of T-2 toxin on chondrocyte activity and the secretion of sGAG.

Objective To analyze the relation between ~(99)Tc~m-DTPA renal dynamic imaging and pathological changes in patients with lupus nephritis (LN).Methods Ten normal control and 29 patients with LN underwent ~(99)Tc~m-DTPA renal dynamic imaging.The LN patients were divided into two groups:silent LN (SLN) group,18 patients;and obvious LN (OLN) group,11 patients.For each case,glomerular filtration rate (GFR),peak time (t_p),half excretion time (t_(1/2)) and the excretion rate at 20 min (R_(20)) were calculated.Assessment of renal function on the scintigraphic images was evaluated by nuclear medicine physicians.The t-test,Fisher'exact probability and R×C association were used for data analysis.Results There were significant differences between normal people and two goups of LN in tp(t=5.3,9.3,both P＜0.05),t_(1/2)(t=6.9,12.0,both P＜0.05)and R_(20)(t=10.1,12.1,both P＜0.05).As to GFR,there was significant decrease in OLN patients(t=4.1,P＜0.05),but not in SLN patients(t=1.7,P＞0.05).Diagnoses of renal function by renal dynamic imaging were compared with the renal pathological changes (r=0.2273,P＜0.05).Conclusions ~(99)Tc~m-DTPA renal dynamic imaging is useful for evaluation of the early stage renal function for LN patients and to diagnose LN patients with no symptom of renal impairment.It may help to assess the degree of renal parenchymal damage while obviating the need for renal biopsy in these patients.

Poly ?-glutamate is a biopolymer material that has a good application prospect.The Vitreoscilla hemoglobin(VHb) gene was integrated into the chromosome of Bacillus licheniformis WX-02 by integrative vector pDG1730-vgb.The expression of VHb was confirmed by CO-difference spectra analysis.It was shown by the results of batch cultures in a 3 L bioreactor that biomass and ?-PGA obtained in the recombinant M2 were 25.5 % and 20% higher than those of the control respectively.

This paper is discussed about course system construction of Microbiology, teaching method, in- struction means and experimental teaching mode. Teaching practice indicated that reform the pattern of Mi- crobiology educational mode can stimulate students’ interest in studying the course, cultivate their inde- pendent ability to solve questions, develop their creative thinking. It is an important way to train high-caliber talents.

AIM:To study the feasibility of recombinant adeno-associated virus(rAAV)as a vector to transfer the green fluorescent protein(GFP)gene as a target gene into rabbit retina.METHODS:Intravitreal injection of rAAV-gfp was performed in either eye for each rabbit with the other eye taken as control.At the 3rd,7th,and 14th day after injection,the eyeballs were removed,and the retinas were flat-mounted on glass slides to inspect the retinal fluorescence,respectively.RESULTS:After intravitreal injection of rAAV-gfp,the presence of fluorescent spots in the cytoplasm of retinal cells indicated that GFP gene was efficiently transferred and expressed in the rabbit retina.CONCLUSION:Recombinant adeno-associated virus is a reliable and simple vector for transferring target gene,e.g.,GFP gene,to the retina.
