OBJECTIVE:
To investigate the genetic polymorphisms of 21 autosomal STR loci of Fujian Han population and evaluate the forensic application value of GlobalFiler Express kit.
METHODS:
Amplified with GlobalFiler Express kit, DNA samples were obtained from 741 unrelated individuals of Fujian Han population. The population genetics parameters of 21 autosomal STR loci were calculated.
RESULTS:
The 21 autosomal STR loci were found to be no deviation from Hardy-Weinberg equilibration (P > 0.05) and relatively abundant in high polymorphism. Heterozygosity ranged from 0.589 to 0.914, power of discrimination ranged from 0.754 to 0.992, polymorphic information content ranged from 0.520 to 0.940, and power of exclusion ranged from 0.278 to 0.825. The SE33 locus was the highest degree in polymorphism.
CONCLUSION
The 21 STR loci of GlobalFiler Express kit have high value in discrimination power and can be useful in personal identification and paternity test in Fujian Han population.

Objective To investigate the etiological factors, clinical features and prognosis of non- traumatic rhabdomyolysis(RML). Methods The medical records of 13 non-traumatic RML patients hospital- ized between 1995-2006 were reviewed. The etiological, clinical, laboratory and therapeutic data were anal- ysed. Results Among 13 patients with non-traumatic RML, multiple factors were responsible for rhabdomyol- ysis in eight patients and single etiologic factor in 5 patients. Different etiological factors were identified, in- cluding 6 with excessive exercise, 3 with hyperpyrexia, 3 with drugs(including illicit drugs, fenofibrate, cy- closporine), 3 complicated with inflammatory myopathy and 2 with limbs compression. Nine patients had myal- gia and muscle weakness, 6 patients had abnormality in nervous system, 4 patients had hyperpyrexia, 3 pa- tients had digestive symptoms. Nine patients were complicated by coagulation disorders and 6 with acute renal failure(ARF). The serum levels of creatine kinase(CK)were decreased to normal within one month in 6 patients, the patient whose rhabdomyolysis was induced by fenofibrate with diabetes and chronic renal failure showed to inadequate decrease within 60 days. Three patients whose problem was induced by inflammatory myopathy, CK levels decreased within 4 months and 6 months in 2 patients, respectively, but CK level was not returned to normal level in one patient during the 80 follow-up days. Three patients died from multiple causes, such as ARF, coagulation disorders,electrolyte and metabolic disturbances. Conclusion Excessive exercise is the most common cause of non-traumatic RML, followed by drugs and inflammatory myopathy. The prognosis is poor in patients with multiple etiological factors and ARF.

OBJECTIVETo constitute a model of B immunoblastic lymphomas in the Hu-PBL-SCID mice.
METHODSThe SCID mice were reconstituted by intraperitoneal injection (i.p.) of 5 x 10(7) human lymphocytes from Epstein-Barr virus (EBV) seronegative individuals. After one week, the SCID mice were inoculated with EBV by i.p. injection, and subjected to the investigation of whether there was any tumor in the abdomen of such SCID mice four weeks later. The characteristics of the found tumor was observed by the methods of Hematoxylin-eosin (HE) stain, immunohistochemical staining and polymerase chain reaction (PCR).
RESULTSCompared with the control groups, all the EBV-infected Hu-PBL-SCID mice had abdominal solid tumors [(32 +/- 12.5) mm3] developed, often located in the liver. HE staining and immunohistochemical staining showed the tumors were human B cell lymphomas. EBV DNA could be detected in the tumors by the PCR.
CONCLUSIONSThe model of B immunoblastic lymphomas in the Hu-PBL-SCID mice is successfully constituted, and may well be useful to the human tumor immunological study.

OBJECTIVETo study the expression of VEGF, KDR, MMP-1, and its transcription factor Ets-1 on the interstitial neovasculogenesis in human cervical carcinoma on molecular level, which may provide further theoretic bases on judgement of prognosis and explain interregularity between neovasculagenetic factors.
METHODSVEGF, KDR, MMP-1, and Ets-1 were detected in 87 cervical carcinomas by in situ hybridization and immunohistochemistry. The survival curves for patients with detected tumors were compared with the curves for those without tumors. Multivariate analyses were performed with Pearson analysis.
RESULTSVEGF mRNA and its protein were mainly expressed in cytoplasms of tumor cells, positive rate was 78.6% (68/87) and 70.4% (61/87) respectively. KDR mRNA and its protein were mainly expressed in vascular endothelial cells, as correlation coefficient between KDR and VEGF was 0.892. Over expression of MMP-1 was seen in both endothelial cells and tumor cells, especially in hyperplasia of endothelial cells. Ets-1 was mainly expressed in both endothelial cells and tumor cells, correlation coefficient between Ets-1 and KDR, MMP-1, was 0.900 and 0.873, respectively. Four factors of above were highly related with tumor differentiation, lymph nodes metastasis as well as 5 years survival rate.
CONCLUSIONSVEGF, KDR, MMP-1, and Ets-1 are important factors on neovasculogenesis in cervical carcinoma, which may be considered to be reference indicator for determining biology behavior of cervical carcinoma, and may provide further theoretic bases on antineovasculagenetic therapy.

OBJECTIVETo investigate the impact of omeprazole on platelet response to clopidogrel and the effect of polymorphisms of CYP2C19 on the antiplatelet effect of clopidogrel.
METHODSPlatelet aggregation (PA) was assessed before 300 mg aspirin plus 300 mg loading dose of clopidogrel and after 300 mg aspirin plus 75 mg maintenance dose of clopidogrel 7 days later in 414 patients with acute coronary syndrome who have undergone percutaneous coronary intervention (PCI). Thereafter, gastric mucosal protective drugs were given (omeprazolem 20 mg, n=224 or cimetidine 800 mg, n=190). Fourteen days later, PA was measured again. Genotypes of CYP2C19*2 were analyzed with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).
RESULTSAfter taken aspirin and clopidogrel, PA has decreased significantly in both groups. Compared with cimetidine, omeprazole had no significant impact on PA on 7 and 21 days post PCI. Compared with homozygotes or heterozygotes for the wild-type CYP2C19*2, patients with CYP2C19*2 AA genotype had significantly higher PA on 7 and 21 days post PCI (P<0.05).
CONCLUSIONNo attenuating effect on platelet response to clopidogrel has been observed for Omeprazole. The variant of CYP2C19*2 AA genotype is significantly associated with attenuated response to clopidogrel.

OBJECTIVETo investigate the trend of total cancer mortality in Linqu County Shandong Province from 1980 to 2002.
METHODSA retrospective survey on all causes of death in 1980 - 1982, 1990 - 1992 and 2000 - 2002 was conducted in Linqu County, a high risk area of gastric cancer in Northeast of China, respectively.
RESULTSThe cancer death, was found the third leading cause of death in 1980 - 1982 in Linqu County, and the second to that of vascular disease in 2000 - 2002. The cancer mortality (standardized mortality) was 108.97/100,000 (111.48/100,000), 132.38/100,000 (127.94/100,000) and 148.48/100,000 (105.53/100,000) in 1980 - 1982, 1990 - 1992 and 2000 - 2002, respectively. The trend of cancer mortality was significantly increased (Z = 13.42, P < 0.0001). The added cancer-eliminated life expectancy in three periods was 2.46 years, 3.29 years and 3.76 years in male (F = 13.99, P < 0.0001), and 1.67 years, 2.30 and 2.33 years in female (F = 13.61, P < 0.0001), respectively. The standardized mortality of gastric cancer (percentage in all cancer death) was 44.93/100,000 (40.29%), 41.37/100,000 (32.34%) and 27.73/100,000 (26.90%) in 1980 - 1982, 1990 - 1992 and 2000 - 2002, respectively. The trend of gastric cancer standardized mortality was significantly reduced (Z = 6.35, P < 0.01).
CONCLUSIONThe mortality of cancer in Linqu County has been increased from 1980 to 2002, but no such trend was found after adjusting ages. However, there was a decreased trend on standardized mortality of gastric cancer in the past 20 years.

OBJECTIVETo develop a novel scaffolding method for the copolymers poly lactide-co-glycolide acid (PLGA) to construct a three-dimensional (3-D) scaffold and explore its biocompatibility through culturing Schwann cells (SCs) on it.
METHODSThe 3-D scaffolds were made by means of melt spinning, extension and weaving. The queueing discipline of the micro-channels were observed under a scanning electronic microscope (SEM).The sizes of the micropores and the factors of porosity were also measured. Sciatic nerves were harvested from 3-day-old Sprague Dawley (SD) rats for culture of SCs. SCs were separated, purified, and then implanted on PLGA scaffolds, gelatin sponge and poly-L-lysine (PLL)-coated tissue culture polystyrene (TCPS) were used as biomaterial and cell-supportive controls, respectively. The effect of PLGA on the adherence, proliferation and apoptosis of SCs were examined in vitro in comparison with gelatin sponge and TCPS.
RESULTSThe micro-channels arrayed in parallel manners, and the pore sizes of the channels were uniform. No significant difference was found in the activity of Schwann cells cultured on PLGA and those on TCPS (P larger than 0.05), and the DNA of PLGA scaffolds was not damaged.
CONCLUSIONThe 3-D scaffolds developed in this study have excellent structure and biocompatibility, which may be taken as a novel scaffold candidate for nerve-tissue engineering.
