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.

Objective To survey the relationship between myocardial damage of chronic and latent Keshan disease with A360P missense mutation in desmin gene exon6. Methods By clinical epidemiology method,30 cases had been collected randomly among chronic Keshan disease patients and 30 cases equally among healthy adults (inner control groups) in Diantou town,Huangling county,Shaanxi province,a Keshan disease area,and 30 cases among health adults(outer control group) in Chang'an district,Xian city,a normal area. Genome DNA had been extracted from 90 blood samples. Different restriction sites had been analyzed by the methods of PCR,digested by restriction endonuclease and electrophoresis. By virtue of Bsp1286 Ⅰ enzyme,122 bp and 60 bp strap could be found in control group from exnn4,showing that Bsp1286 Ⅰ enzyme was active. By virtue of Bsp1286 Ⅰ enzyme,desmin gene exon6 was digested to 184 bp and 66 bp strip when A360P missense mutation site exited in exon6. Results One hundred and twenty two bp and 60 bp strap could be found in control group from exon4 digested by Bsp1286 Ⅰ ,which showed Bsp1286 Ⅰ enzyme was active. Two hundred and fifty bp strips can only be found in digest products of exon6. One hundred and eighty-four and 66 bp strips which were the products of DNA digested by Bsp1286 Ⅰ could not be found. A360P missense mutation site of desmin gene exon6 had not been found among chronic and latent Keshan disease patients and tow control groups in Keshan disease area and in normal area. Conclusions A360P missense mutation site of desmin gene exon6 has not been found among chronic and latent Keshan disease patients. A360P missense mutation of desmin gene exon6 probably is not predisposing genes of chronic Keshan disease.

Triamcinolone acetonide is one of adrenocorticotropic hormones. Its anti-inflammatory and anti-allergic effects are strong and lasting. However, due to its poor water solubility and systemic side effects, researchers try to transform and create its new formula constantly. The paper reviewed the research progress in new formula of triamcinolone acetonide at home and abroad in recent years, including solid dosage forms, emulsion, particle dispersion system and the other new formula which have been researched in or-der to provide information for the improvement of bioavailability and safety.

Objective To evaluate the mitochondrial function of chondrocytes in Kashin-Beck disease (KBD) patients and its correlation with age.Methods Mitochondrial function was evaluated by analyzing the activities of respiratory chain enzyme complexes and citrate synthase (CS),intracellular adenosine triphosphate (ATP)contents, changes in mitochondrial membrane potential (ΔΨm),as well as the intracellular reactive oxygen species (ROS) contents.Correlation of mitodhondrial function and age was analyzed with linear regression.Results Activities of complexes Ⅱ (P = 0.001 ),Ⅲ (P = 0.005 )and Ⅳ (P = 0.005 )were reduced in KBD articular chondrocytes compared with cells from normal controls.However,the mitochondrial mass was increased in KBD samples. Cultured KBD chondrocytes had reduced cellular ATP level (P = 0.001 )and mitochondrial membrane potential (P =0.001),but increased citrate synthase activity (P =0.04)and intracellular ROS level (P <0.001).We found no correlation between mitochondrial function and donor age either in normal or in KBD chondrocytes. Conclusion Mitochondrial function is altered in articular chondrocytes of KBD,and no correlation was found between mitochondrial function and donor age.

Objective To investigate the effects of pyrroloquinoline quinone(PQQ) on the hippocampal neurons of aged rats induced by D-galactose(D-gal).Methods D-gal was used to induce the model of aging rat,PQQ was administered into rat lateral intracerebroventricle.After 50 days the metamorphosis of hippocampal neurons was observed by H-E and Nissl's staining.The apoptosis rate of hippocampus was tested by flow cytometry.The contents of free radical and C-FOS protern were measured.Results Compared with the control group,the size of the neurosoma was slightly changed,the optical density of Nissl's was decreased,the content of free radical and the apoptosis rate increased markedly in D-gal group.After PQQ injection with D-gal,the size of neurosoma and the optical density of Nissl's were markedly increased,the content of free radical and the apoptosis rate of hippocampus did not change.PQQ improved the expression of C-FOS protern.Conclusion PQQ can slow down the aging progress of hippocamal neurons induced by D-gal.

In order to save the expense for hospitals,a simple bomu light treating instrument is developed by ourselves.It consists of bomu light,12V/24V transformer,5/50W variable potentiometer,silicon,capacitor,plugs and the worn ATX box.Although the structure is simpler and cost is lower,it can accomplish every treating function for gynecology.
