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 observe the effect of daidzein on intima proliferation of rat common carotid artery injured by balloon. Methods 24 male Wistar rats were randomly assigned to 3 groups, 8 rats per group: high dose daidzein group (100 mg/kg?d), low dose daidzein group (50 mg/kg?d) and dissolvent control group. Duplicate the rat common carotid arteries injured by balloon models. Five weeks after operation, serum biochemical indicator such as TC, TG, BUN, ALT and MDA were measured using routine biochemical methods. And pathological sections of common carotid arteries were observed and the changes of vascular histomorphology were estimated by computer analysis of photomicrograms. Results Compared with control group, the intima areas was significant decreased in high dose group and low dose group (86 893?83 452 ?m2 vs 199 419?103 352 ?m2 vs 222 324?56 154 ?m2,P0.05). Conclusion Daidzein can inhibit the intima proliferation of Wistar rat common carotid arteries injured by balloon.

ObjectiveTo explore clinical characteristics of fatality cases of hand foot and mouth disease caused by enterovirus 71 (EV71),and to improve the diagnosis and treatment of the disease.Methods Sixteen children infected with EV71 were retrospectively reviewed.Clinical manifestation,laboratory data and death causes were analyzed.ResultsAll cases were younger than four years,and the mean age was 18.9 months.Seasonal variations in incidence were observed,with a peak in incidence during the summer season.These cases typically presented with a brief duration of febrile illness,nonspecific neurological signs including headache,vomiting,limb tremor and convulsions.After two to four days,they all got sudden deterioration,manifested with tachycardia,poor peripheral perfusion,tachypnea and transient hypertension.After intubation,they all had pink frothy or blood from the endotracheal.Tweleve of them died from pulmonary edema or pulmonary hemorrhage,and acute refractory cardiac dysfunction.The other four of cases died from brain stem encephalitis.Atypical presentation such as absence of skin rash should alert the physician.Total white cell count,blood glucose and cardiac troponin I were raised significantly.The protein raised in cerebrospinal fluid.ConclusionHand foot and mouth disease caused by EV71 progresses rapidly.The primary site of attack is the central nervous system,particularly the brainstem,and the cause of death are neurogenic pulmonary edema and/or hemorrhage,acute refractory cardiac dysfunction.

AIM: To improve on the acute cumulative death rates method in animal by intravenous (iv) administration. METHODS: A mathematic model was established to simulate the pharmacodynamic and pharmacokinetic process by the program written by Visual Basic.net. This program evaluated the acute cumulative death rates (ACD method) for use of pharmacokinetics of traditional Chinese medicine (TCM). RESULTS: The ACD method related on its first dosage, and an unsuitable dosage could lead to a wrong results. It also had been proved that, by adjusting the 2nd dosage it was a more suitable to wider range of dosage. CONCLUSION: By suitable 2nd dosage and enough animal number, ACD method can be used in the pharmacokinetics of TCM.
