Objective To analyze the allele frequencies of 5 short tandem repeat(STR)loci(D12S313,D12S304,D12S1640,D12S1708 and D12S1583)on chromosome 12 among Kashin-Beck disease(KBD)patients and the control population living in the area suffered from KBD.Methods Fifty KBD patient8 and 50 non-KBD patients were chosen in endemic afea of Shaanxi Province,5 STR loci on chromosome 12 were genotyped by the technology of polymerase chain reacfion(PCR)and capillary electmphoresis.The pelymorphisms of STR in these popIllations were analyzed.The allele and genotype frequencies of each STR in the corresponding groups were caleulated and compared. Results In KBD group,the 5 STR loci had 8,6,7,5 and 11 types ofalleles and 17,11,15,8 and 28 genotypes, respectively;while in the control group,the number of aUele types of 5 STR loci were 6,8,6,4 and 10,the number of genotype of those loci were 13,21,14,8 and 23,respectively The allele frequence of D12S304 locus was statiBtically significant between KBD patients and controls(P<0.05),especially for the 319 bp allele(P<0.006 25). Conclusion There is an association between D12S304 locus and KBD.The 319 bp allele might play the key role.

AIM: Using functional magnetic resonance imaging, to inspect v sual cortex physical reactions stimulated by rotating grating, and to its components. METHODS: On 1.5T MR scanner, GRE-EPI imaging sequence was carried on 9 h discover ealthy volunteers, the visual cortex response data were processed after delinearation by SPM99.RESULTS: Different components of rotating grating excited different areas of the visual cortex. Dramatic response in the central part of the occipital lobe, which was related to white light stimuli, located at primary visual cortex. Response area in bilateral Broadaman 19 areas was related to vision-motion function. And weak response area in the central part of the occipital lobe was related to shape perception.CONCLUSION: Rotating grating conclude plenty of visual information, and it excites different areas of the optic center as a stimuli. fMRI is a valuable equipment to study the physiology of visual cortex.

Poly(ADP-ribose) polymerase-1 (PARP-1) has emerged as a promising anticancer drug target due to its key role in the DNA repair process. It can polymerize ADP-ribose units on its substrate proteins which are involved in the regulation of DNA repair. In this work, a novel series of para-substituted 1-benzyl-quinazoline-2, 4 (1H, 3H)-diones was designed and synthesized, and the inhibitory activities against PARP-1 of compounds 7a-7e, 8a-8f, 9a-9c and 10a-10c were evaluated. Of all the tested compounds, nine compounds displayed inhibitory activities with IC50 values ranging from 4.6 to 39.2 micromol x L(-1). In order to predict the binding modes of the potent molecules, molecular docking was performed using CDOCKER algorithm, and that will facilitate to further develop more potent PARP-1 inhibitors with a quinazolinedione scaffold.

OBJECTIVETo approach the central nervous mechanism of abdominal acupuncture by using resting-state functional magnetic resonance imaging (fMRI).
METHODSTwelve old healthy volunteers were treated by standardized abdominal acupuncture with invigorating the kidney and nourishing marrow method and Zhongwan (CV 12), Xiawan (CV 10), Qihai (CV 6), Guanyuan (CV 4), Qixue (KI 13), Shangqu (KI 17) and Huaroumen (ST 24) were selected. They were examined by using resting-state fMRI before and after treatment of abdominal acupuncture and the brain functional connectivities were analyzed based on bilateral hippocampus chosen as seed points.
RESULTS(1) Before acupuncture, functional connectivities were found in the bilateral middle frontal gyrus, bilateral superior temporal gyrus, bilateral middle temporal gyrus, bilateral thalamus, bilateral subiculum hippocampi, bilateral insula, the cupula and declivis of right cerebellum, left superior frontal gyrus, left head of caudate nucleus, left posterior cingulate gyrus and left inferior parietal lobule (all P < 0.05). (2) After acupuncture, functional connectivities were found in the bilateral superior frontal gyrus, bilateral superior temporal gyrus, bilateral middle temporal gyrus, bilateral thalamus, bilateral insula, bilateral subiculum hippocampi, bilateral inferior parietal lobule, bilateral postcentral gyrus, bilateral cingulate gyrus, right head of caudate nucleus, right middle occipital gyrus and right posterior cingulate gyrus (all P < 0.05). (3) After acupuncture, there were intensity functional connectivities greater than before acupuncture in the bilateral superior frontal gyrus, bilateral middle frontal gyrus, bilateral superior temporal gyrus, bilateral superior parietal lobule, right inferior frontal gyrus, right anterior cingulate gyrus, right fusiform gyrus, right precuneus and right postcentral gyrus, while the intensity of functional connectivities of left middle temporal gyrus, right lingual gyrus, left cuneus/precuneus and left inferior parietal lobule were attenuated.

OBJECTIVESTo introduce the method and experience of three-piece inflatable penile prosthesis for treatment of erectile dysfunction (ED).
METHODSBoth AMS700CX/CXM and MENTOR ALPHA I three-piece inflatable prosthesis were used for 48 cases of ED.
RESULTSThere were no rejection, mechanical problems, urethral injury and penile skin necrosis after surgery. All patients had satisfaction of sexual life. Only one case had trauma of tunica albuginea (2.08%) and the implantation had to be cancelled. There were 2 cases of post-operative infection (4.17%), 10 cases of prepuce edema(20.8%), 8 cases of penile pain(16.67%). The effective rate was 97.9% and satisfaction rate was almost 100%.
CONCLUSIONSThree-piece inflatable penile prosthesis was more compatible to human physiology. It is natural, easy to hide and use, and it caused little trauma in surgery with high rate of successful implantation and patient satisfaction. It was indicated for all kinds of ED, especially suitable for refractory and drug incurable ED patients.

OBJECTIVETo study the expressions of MMP-2 and TIMP-2 mRNA on cultured rat mesangial cells (MsC) and in human diseased glomeruli, and to explore their significance in the development of glomerulosclerosis.
METHODSThe expressions of MMP-2, TIMP-2, and Col IV mRNA on cultured rat MsC stimulated by IL-1 or/and TGF-beta1 were investigated through Northern blot analysis. The levels of MMP-2 and TIMP-2 mRNA expressions and immunoreactivity of PCNA and Col IV in human diseased glomeruli from renal biopsies of lupus nephritis (LN) patients were examined by in situ hybridization and immunohistochemistry, respectively.
RESULTSThe levels of MMP-2, TIMP-2, and Col IV mRNA expressions were markedly increased on cultured rat MsC stimulated by IL-1 or/and TGF-beta1. Meanwhile, upregulation of MMP-2 and TIMP-2 mRNA expressions was confirmed in diseased glomeruli from patients with various subtypes of LN, and was closely related to the positive cell number of PCNA presentation and deposition of Col IV in glomeruli.
CONCLUSIONThe results suggest that the over-expressions of MMP-2 and TIMP-2 mRNA on glomerular cells might play a critical role in the development of glomerulosclerosis.
