Objective To study the genetic polymorphism and frequencies of 15 STR loci in 10071 unrelated individuals of Han nationality, which are compared with the data reported previously. Methods 15 STR loci were amplified in DNA samples from 10071 unrelated individuals in Guangdong Han population using PowerPlex~(TM) 16 system, which were genotyped with ABI 377 or 3100 Genetic Analyzer. Frequencies for 15 STR loci were obtained. Results Except D8S1179 locus, rare alleles were found in the other 14 STR loci. The number of rare alleles ranged froml to 7 in the 14 STR loci ,which increased up to 34 rare alleles, including D21 S11 (32.1 and 36.2), D18S51 (15.2 and 17.2), Penta E (15.2, 17.4, 18.4, 19.4, 26 and 27), D7S820 (9.2, 10.1, 11.1 and 15), Penta D (18, 19 and 20), TPOX (14) and FGA (13) which were detected the first time and D21S11 (30.3), D7S820(9.1 and 9.2) which were frequently seen in the population although infrequent in European population. Conclusion More rare alleles can be detected with genetic polymorphism data from a lager number of individuals and more credible frequencies of alleles be obtained.

Objective: To investigate the therapeutic effect and safety of Jian Shen Li Shui No. 1 for treatment of acute cerebral hemorrhage. Methods: The patients enrolled were randomly devided into 3 groups. The group A were treated with Jian Shen Li Shui No. 1, the group B with Xing Nao Xiao Zhong Capsules and the group C with 20% mannitol. Symptoms and signs, changes of urine volume, quality of life, routine examination of blood, urine and feces, function of liver and kidney, electrocardiogram, blood lipid, sugar, electrolytes, reological changes were observed. Results: The total effective rate in the group A was superior to that in the group B(P0. 05) ; while the cured and markedly effective rate in the group A was better than that in the group C (P

Objective To discuss the probability of siblings identification by autosomal short tandem repeat (STR). Methods 150 pairs of full siblings and 150 pairs of unrelated individuals were genotyped by the 15 STR loci of Power Plex?6 system. Paternity index of full siblings (Pips) and paternity probability of full siblings (WFS) were calculated with the method of ITO. WFS and allelic matching of the two groups were compared, and three sorts of allelic matching in each pair were tested by chi-square test. Results Wps of 100 pairs of siblings (66.67%) were more than 0.9995; WFS of unrelated individuals were less than 0.8, and that of 100 pairs (66.67%) were less than 0.27. The locus number of the entire-same ranged from 1 to 10, averaged 5.49 in siblings, while in unrelated individuals ranged from 0 to 5 and averaged 1.33; that of the entire-different ranged from 0 to 6, averaged 1.66 in siblings but ranged from 2 to 11 and averaged 6.57 in unrelated individuals; that of the half-same ranged from 3 to 13, averaged 7.85 in siblings, and ranged from 1 to 13, averaged 7.11 in unrelated individuals. By chi-square test, there was significant difference (P0.05) in the half-same between the two groups. Conclusion It is effective to identify siblings by Power-Plex?6 system. Testing of 15 STR loci of PowerPlex?6 system, it suggested that the pair were unrelated individuals when the locus number of the entirely-different is not less than 6 or that of the entirely-same is zero, and that the pair were siblings when the locus number of entirely-different is not more than 1 or that of the entirely-same is not less than 6.

ObjectiveTo explore the development and mechanism of hepatic cell apoptosis, and the effect of anti-apoptosis apoptosis of Se in the liver in obstructive jaundice rats. Methods(GPx) activity and (ROS) level were measured by biochemical methods,terminal-deoxynucleotidyl medicated nick end labeling (TUNEL)in different groups at different time points, and analysed by multivariate regression. Results Apoptosis cells appeared on day 3 after common bile duct(CBD) ligation ,significantly increased on day 7,reached the peak level on day 11, and began to decrease on day 14. The longer the time of obstructive jaundice in rats, the higher the level of ROS and apotosis index(AI), while the level of GPx decreased progressively. AI reached the peak 11-day after CBD ligation. Less hepatic apoptosis appeared after the rats treated with Se at every time point (P

Objective To report the clinical outcome and prognostic factors for locally recurrent nasopharyngeal carcinoma(NPC)treated with intensity modulated radiotherapy(IMRT).Methods From January 2001 to August 2004,the data of 132 such NPC patients were analyzed retrospectively;104 male and 28 female with a median of 44.5 years(range 21-73 years).Ninety-eight patients(74.2%)were confirmed by biopsy as having NPC:9 with WHO TypeⅡand 89 WHO TypeⅢ.The other 34 patients were only diagnosed by MRI scan because of the extension/invasion was in the base of skull and/or cavernous sinus.Median interval time were 24 months(range 6-184 months).According to the 1992 Chinese Fuzhou Staging System:stageⅠ3.8 %,Ⅱ10.6 %,Ⅲ22.0% andⅣa 63.6%;T1 5.3%,T2 10.6%,T3 22.7% and T4 55.3%.Twenty-two patients had recurrence in the neck lymph nodes.IMRT was given with the sequential tomotherapy system(NOMOS Peacock systems)of 6 MV X-rays.Prescription dose was 60-70 Gy in GTV,with the fractional dose of 1.94-2.8 Gy.Sixty patients were also supplemented with two to six courses of cisplatin-based chemotherapy.Results The median volume of GTV was 39.5 cm~3(range 0.8-158.9 cm~3).The D95,V95,mean dose and fractionation dose of GTV was 66.9 Gy,98.3%,69.8 Gy and 2.32 Gy,respectively.The median follow-up time was 12 months(range,2-47 months).The 1-,2-and 3-year local progression-free rate was 96.4%,88.4% and 85.3%,respectively.The overall 1-,2-and 3-year survival rate was 6.5.9%,49.6% and 41.6%,respectively.Eleven patients developed distant metastases.Forty-seven patients were observed to devdop mucosa necrosis and/or massive hemorrhage in the nasopharynx.On univariate and multivariate analysis,fractional dose and vohane of GTV were significant prognostic factors for overall survival(P=0.016,0.009).Conclusions The local control and survival rate can be improved for patients with locally recurrent nasopharygeal carcinoma after treatment of intensity modulated radiotherapy.The fractional dose and volume of GTV are independent prognostic factors for the overall survival. The main death reasons are mucosa necrosis and/or massive hemorrhage in the nasopharynx.
