OBJECTIVETo investigate the association between p53 Arg72Pro polymorphism and cervical carcinomas HPV-associated cervical carcinoma in Uigur and Han women.

METHODSThe distribution and frequencies of p53 Arg72Pro genotypes were determined by PCR-RFLP in 152 cases of cervical carcinoma in ethnic Uigur women with 110 cases of normal control and 120 cases of cervical carcinoma in Han women with 122 cases of normal control.

RESULTSThe omni-constituent ratio of p53 genotype was statistically different between cervical carcinoma and normal control groups in the Uigur (chi(2) = 7.196, P < 0.05) group. The proportion of Arg/Arg was higher in cervical carcinomas than that in control. The omni-constituent ratio of p53 genotype was statistically different between cervical carcinoma and normal control groups in Han (chi(2) = 8.231, P < 0.025). The proportion of Pro/Pro was higher in cervical carcinoma than that in normal control. The omni-constituent ratio was statistically different between HPV 16 positive and negative groups of cervical carcinoma in the Uigur group (chi(2) = 7.177, P < 0.05). The proportion of Arg/Arg was higher in HPV 16 positive group than that in HPV 16 negative group.

CONCLUSIONSp53 Arg72Pro polymorphism may be associated with the development of cervical carcinoma in Uigur and Han women in Xinjiang. p53 Arg/Arg genotype may be a genetically susceptible factor to HPV-associated cervical carcinoma in Uigur. p53 Pro/Pro genotype may be a genetically susceptible factor to cervical carcinoma in Han. There may be different susceptibilities to cervical cancer between Uigur and Han women in Xinjiang.

OBJECTIVETo detect and study the types of Borrelia burgdorferi sensu lato in ticks and rodents from Da Xing-An Mountains Forest areas of China.

METHODSNested PCR was performed to amplify 5S-23S rRNA intergenic spacer of B. burgdorferi. Positive products were analysed by restriction fragment length polymorphism (RFLP) and single strand conformation polymorphism (SSCP), specimens showing unique RFLP profile were sequenced and analysed.

RESULTS1336 Ixodes persulcatus, 144 Dermacento silvarum, 144 Haemaphysalis concinna and 145 rodents of 9 species were collected from 16 sections of Da Xing-An Mountains Forest areas of China. Specific fragments were amplified from 293 I. persulcatus and 6 D. silvarum and 5 rodents of 4 species. B. burgdorferi was not detected in H. concinna. Among the positively tested I. persulcatus, 209 contained B. garinii genospecies and 45 contained B.afzelii genospecies based on RFLP. Moreover, B.garinii genospecies consisted of B. garinii 20047 and B. garinii NT29. 17 adult I. persulcatus were simultaneously infected with B. garinii 20047 and B. garinii NT29. Nine adult I. persulcatus were simultaneously infected with B. garinii 20047 and B. afzelii. Four adult I. persulcatus were simultaneously infected with B. garinii 20047 and B. garinii NT29 and B. afzelii. Two D. silvarum were infected with B. garinii 20047, 1 D. silvarum with B. garinii 20047, 2 D. silvarum with B. afzelii. 3 rodents were infected with B. garinii 20047 while 2 rodents were infected with B. garinii NT29. Mixed infection was not found in D. silvarum and rodents. In addition, nine I. persulcatus and one D. silvarum specimens showed unique RFLP pattern. Data from sequential analysis showed that they all belonged to B. garinii. PCR-SSCP profiles of 5S-23S rRNA intergenic spacer of B. burgdorferi in the positive specimens exceeded 36 types; B. garinii 20047 showed 16 types while B. garinii NT29 showing 11 types, B. afzelii showing 9 types. SSCP profiles of the specimens coinfected with multiple B. burgdorferi was relatively complex.

CONCLUSIONThe infection of B. burgdorferi was found in the ticks and rodents in Da Xing-An Mountains Forests areas. The infection rate of I. persulcatus was high. B. garinii was predominant genospecies, and the population of B. burgdorferi was heterogeneous in the area. Mixed infections of different B. burgdorferi genospecies in ticks were found. I. persulcatus and Clethrionomys rufocanus were possibly served as major vector and major host for B. burgdorferi, respectively, suggesting that further study is needed to confirm the coinfection in humans and animals in this region.

OBJECTIVETo investigate rodents' natural infection of Orientia tsutsugamushi (Ot) in some areas of Inner Mongolia and Xinjiang, China.

METHODSDNAs were extracted from spleens of the captured mice and nested-polymerase chain reaction (nPCR) technique was used to detect the Ot-Sta56 gene. Six positive samples were sequenced and analyzed by Clustal X (5.0) and DNA Club software.

RESULTSA total of 90 rodents were captured in Inner Mongolia, and the overall prevalence of Ot was 6.67%. There was no significant difference in infection rates among the positive rodents species. 20 rodents were captured in Xinjiang, and the prevalence of Ot was 5.00%. The geographical difference in infection rates was not statistically significant between Inner Mongolia and Xinjiang. 9 rodents were captured in farmlands of Inner Mongolia and Xinjiang but there was no positive samples found. 101 rodents were captured in grasslands, and the prevalence of Ot was 6.93%. The Sta56 gene nucleotide sequence homology to Karp strain of N59 (from Microtus maximowiczii), N69 (from Cricetulus barabensis) and X33(from Cricetus cricetus) was 99%. The sequence homology to Taitung-2 strain and TW461 strain of N65 (from C. barabensis) was 94%, and the sequence homology to Taitung-2 strain and TW461 strain of N88(from Apodemus agrarius) was also 94%. The sequence homology to Oishi strain of N90 (from A. agrarius) was 96.00%.

CONCLUSIONOur findings indicated that infections of Ot did exist in rodents captured from Inner Mongolia and Xinjiang. The genotypes of Ot in Inner Mongolia and Xinjiang were quite complex, with some of them belonged to Karp type, and the others belonged to Taitung-2, TW461 and Oishi types which providing evidence for further investigation on the scrub typhus fuci in the two areas.

In order to evaluate the incidence of chromosomal abnormalities in patients with polycythemia vera (PV) accurately and to investigate the value of fluorescence in situ hybridization (FISH) technique in the detection of trisomies 8 and 9, conventional cytogenetics (CC) technique was used to detect karyotype and interphase FISH was used to detect trisomies 8 and 9 in 50 newly diagnosed PV and 8 normal individuals. The results showed that out of 50 cases, the 3 cases had chromosome karyotype abnormality, including trisomy 8, deletion of chromosome Y and inversion of chromosome 11 by CC technique. FISH method detected two cases of trisomy 8, including one case confirmed by CC technique, and one case of trisomy 9 neglected by CC technique. It is concluded that the incidence of chromosomal abnormalities in patients with PV is rare, and the incidence of trisomy 8 and trisomy 9 found in this study are relatively lower than that have been reported which may be related to the limited number of samples. Interphase FISH, as an important complement to CC, is a useful method for the detection of trisomies 8 and 9.

OBJECTIVETo investigate the outcome of orthotopic heart transplantation for patient with end-stage hypertrophic cardiomyopathy.

METHODSThis retrospective review analyzed the clinical data of nine patients (7 males) undergoing orthotopic heart transplantation for end-stage hypertrophic cardiomyopathy in our center. All patients received induced therapy protocols peri-operative and standard triple maintenance immunosuppressive therapy postoperative.

RESULTSOne recipients developed acute renal failure due to renal artery embolism and allograft rejection in the early posttransplantive course, symptoms and signs were improved under continuous renal replacement therapy and steroid-pulse therapy, this patient died of sudden cardiac arrest at 32 months post transplantation. Another recipient developed demyelinating disease in frontal and parietal lobe and finally recovered with medical therapy. Eight patients survived the operation with good quality of life and there was no episode of rejection or infection or chronic graft arteriosclerosis during follow-up time. Three recipients developed left ventricular hypertrophy and there were no signs of grapg-vessel diseases in the survivals.

CONCLUSIONHeart transplantation is the best therapeutic option for selected patients with end-stage hypertrophic cardiomyopathy.
