Osteocalcin is a bone matrix noncollagen protein which is one of the most abundant secretory products of osteoblasts. Resent studies have demonstrated that osteocalcin is not only a specific biochemical marker of bone turnover, but also involved in the regulation of energy metabolism. Further studies in the pathophysiological functions of osteocalcin might contribute to the treatment of obesity, diabetes, and metabolic syndrome.

The genes for TEM and aminoglycoside-modifying enzymes (AMEs) in Acinetobacter baumannii were studied to provide molecular biological support for monitoring their drug resistance.MethodsTwenty strains of Acinetobacter baumannii were clinically isolated from the period of August, 2002 to Feburary, 2004. The drug resistance of these strains to thirteen kinds of antimicrobial agents was tested by microdilute test. The TEM and AMEs genotypes of these strains were analyzed by polymerase chain reaction and verificated by DNA sequencing .Results All twenty strains were sensitive to Imipenam and Meropenem. The resistant rates of the twenty strains to Piperacillin/ Tazobactam, cefepime and ceftazidime were 45.0%, 65.0% and 70.0%, respectively. The resistant rate to aminoglycosides antibiotics was 75.0%. The resistant rates to other antimicrobial agents were greater than 65.0%. The positive rate of genotype TEM, aac(3)-Ⅰ, aac(3)-Ⅱ aac(6”)-1 and ant(3”)-Ⅰ were 45.0%, 55.0%, 15.0%, 35.0%, and 60.0%, respectively. The genotypes of SHV, AmpC DHA and AmpC MIR were all tested negative.Conlusions The multiple-drug-resistance of Acinetobacter baumannii isolated from Tongde Hospital was a serious issue.There were high percentages of TEM and AMEs genotypes. Because of the imperfection frame of the primer,some familiar genes just like OXA,VER and PER were not experimented. We shall further discuss the drug resistance of the third/fourth generations cephalosporin.

Objective To analyze a large number of Cumulative Paternity Index (CPI) data in Single-parentage identification with stochastic simulation method. Methods Using the software in Identifiler, PP18D, AGCU EX20, PP21, AGCU 21+1 system, 1 million groups of STR genotyping of parent-child were analyzed. The average rate of very low CPI (RVLCPI), the median of PI in every loci (MPI), and the average PI of 39 STR loci (PIsolo) were counted out. And calculation formula of the number of STR loci that need more testing (N) was derived. Results RVLCPI in Identiifler, PP18D, AGCU EX20, PP21, AGCU 21+1 system were 24.9%, 6.5%, 1.4%, 0.7%, 0.000 1%. On the premise of inclusion relations between every kits, the number of autosome STR loci is inversely proportional to RVLCPI. PIsolo was 1.843 2. There was a signiifcant positive correlation between MPI and PEduo (r=0.956, P<0.001). The formula of the number of STR loci that need more testing was N=?log1.843 2(10 000/P)?. Conclusion The result and the formula in this paper are effcient in single-parentage identiifcation.

Objective To investigate the outcomes of arthroscopically lateral retinaculum patellae release and medial patellofemoral ligament reconstruction using the semitendinosus tendon autograft for the treatment of habitual or recurrent dislocation of the patella. Methods 18 cases of recurrent dislocation of the patella were included in this group, among which there were 6 males and 12 females. The average age was 20 years old(range from 17 to 24 years). Arthroscopic investigation found tensed lateral retinaculum patellae and damaged cartilage at patellar medial margin and femoral lateral condyle. There were 6 cases of Ⅱdegree cartilage injuries, 5 cases of Ⅲ degrees injuries, and 7 cases of Ⅳ degree injuries caused by patellofemoral joint impact. For cases of Ⅳ degree injuries, the damaged cartilage was shaved and microfractured. For cases of Ⅱ or Ⅲ degree injuries, radiofrequency system was used for debridement. After the lateral retinaculum patellae was extensively released, semitendinosus tendon autograft was used to reconstruct the medial patellofemoral ligament. The knee joint was flexed and extended. Patella's dynamic motion, the tension of the tendon and relationship between the femoral trochlea and patellar bone were arthroscopically observed. Interface screw was used to fix the tendon ends within the bone tunnel on condylus medialis femoris. Results All patients were followed up for 9 to 19 months averaging 13 months. No patellar dislocation occurred postoperatively. Apprehensive test, patella tilt test were negative; and Apley test were negative in 16 patients and positive in 2 patients. One case of inferior pole of patella fractured. Axial view of X-ray and MR images of patella showed 15 cases regained normal anatomical relation of patellofemoral joint. 3 cases had mild semi-dislocation. Lysholm's score averaging (78.0?4.5) points preoperatively and (94.0?3.5) points postoperatively. Conclusion Lateral retinaculum patellae solution and medial part reconstruction under arthroscope can effectively cure recurrent subluxation of the patella and improve knee joint function.
