OBJECTIVETo study FANCA protein expression in Fanconi anemia patient's (FA) cells and explore its function.

METHODSFANCA protein expression was analyzed in 3 lymphoblast cell lines derived from 3 cases of type A FA (FA-A) patients using Western blot. Nucleus and cytoplasm localization of FANCA protein was analyzed in one case of FA-A which contained a truncated FANCA (exon 5 deletion). The FANCA mutant was constructed from the same patient and its interaction with FANCG was evaluated by mammalian two-hybrid (M2H) assay.

RESULTSFANCA protein was not detected in the 3 FA-A patients by rabbit anti-human MoAb, but a truncated FANCA protein was detected in 1 of them by mouse anti-human MoAb. The truncated FANCA could not transport from cytoplasm into nucleus. The disease-associated FANCA mutant was defective in binding to FANCG in M2H system.

CONCLUSIONSFANCA proteins are defective in the 3 FA-A patients. Disfunction of disease-associated FANCA mutant proved to be the pathogenic mutations in FANCA gene. Exon 5 of FANCA gene was involved in the interaction between FANCA and FANCG.

To analyze specific content of Za Liao of Qian Jin Yi Fang, this essay compares its content with related content of Xin Xiu Ben Cao, finding that Za Liao of Qian Jin Yi Fang is derived from the part of Jin An of Xin Xiu Ben Cao, which complements with herbal chapters from volume II to IV of Qian Jin Yi Fang. The texts in Za Liao can verify and collate part of Jin An, and thereby showing important literature value and great help for further studies on traditional Chinese medicines of Tang dynasty.

Geo-authentic herbs lay stress on their producing areas. The producing areas of most geo-authentic herbs have never changed since the ancient times. However, many other geo-authentic herbs have experienced significant changes in the long history. There are two main causes for the change in producing areas of herbs-change of natural environment and development of human society, which are restricted by each other and play a great role throughout the development process of geo-authentic herbs.

Highly active antiretroviral therapy (HAART) for the treatment of HIV infection had a revolutionary impact, with the universal application of the anti-retroviral drugs, HAART-related adverse reactions have attracted more and more attention. HAART-related hyperlipidemia is one of the common adverse reactions with more and more scholars study the pathogenesis and therapy of hyperlipidemia in recent years. This article elaborated the latest research of Chinese medicine treatment of HAART-related hyperlipidemia.

Objective To analyse the characteristics of orbital benign and malignant masses on diffusion weighted imaging in combination with conventional MR imaging and evaluate the diagnostic value of apparent diffusion coefficient in distinguishing benign and malignant orbital lesions.Methods Seventy- seven cases with orbital masses,including fifty-five benign lesions and twenty-two malignant tumors,who underwent conventional MRI and diffusion imaging scanning were studied with use of a 1.5 T magnetic resonance system.Quantitative ADC measurements of masses(ADC_M)and of the white matter of eontralateral temporal lobe(ADC_W)were made with two different b-values of 0 and 1000 s/mm~2.The ADC ratio(ADCR)of the lesion to the control was calculated.The receiver operating characteristic curves(ROC) were constructed using various cut points of ADC_M and ADCR for different parameters to differentiate between benign and malignant masses.The area under the ROC curve for each parameter was also calculated. Results All cases were proved by histopathology.The mean ADC_M and ADCR of benign orbital masses were(1.56?0.75)?10~(-3)mm~2/s and 1.85?0.91,respectively.The mean ADC_M and ADCR of malignant orbital masses were(1.09?0.42)?10~(-3)mm~2/s and 1.28?0.53,respectively.There were significant difference both between ADC_M and ADCR of benign and malignant masses(t=2.803,2.735,P

Highly active antiretroviral combination therapy significantly reduced the mortality, but in the high-speed copying, high genetic variation and drug selection pressure under the effect of the increasingly serious problem of drug resistance greatly weakened the role of HAART inhibit viral replication and reduce antiviral treatment. This paper reports the latest trends in HIV drug-resistance in order to develop anti-HIV drugs in clinical programs, research and development of new guidance anti-HIV-1 strategy to bring guidance.

OBJECTIVE: To investigate the relationship between estrogen receptor (ER) gene polymorphisms and HBV-induced cirrhosis. METHODS: Xba I and Pvu II polymorphisms of ER gene were analyzed in 98 patients with HBV-induced cirrhosis, 72 patients with chronic hepatitis B, and 84 healthy controls by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. RESULTS: The frequencies of Pp genotype and P allele of ER gene in patients with HBV-induced cirrhosis were higher than those in patients with chronic hepatitis B and controls, while the frequencies of pp genotype and p allele of ER gene in patients with HBV-induced cirrhosis were lower than those in patients with chronic hepatitis B and controls (P < 0.05). The risk of HBV-induced cirrhosis occurrence in carriers with Pp and pp genotype was 2.23 folds than that in carriers with pp genotype. There was no significant difference in frequencies of allele and genotype in Xba I polymorphism among the HBV-induced cirrhosis group, the chronic hepatitis B group, and the control group (P > 0.05). CONCLUSION Pp genotype and P allele might be the susceptibility gene for HBV-induced cirrhosis while pp genotype and p allele might be the protective gene.

Through systemically sorting and studying literature of Chinese medicine, this article pointed out that leech used by the traditional Chinese medicine in ancient time has the features of small, living in water, able to suck blood of animal and people. The species of leeches having these features were Hirudo nipponia Whitman, H. pulchra Song, Poecilobdella nanjingensis sp. Nov. , P. manillensis (Lesson) and P. hubeiensis Yang, which were not fully coincidence with the species recorded in Chinese Pharmacopeia of 2010 edition. We suggests that species of leech in Chinese Pharmacopeia be revised: H. nipponica Whitman should be kept, P. manillensis (Lesson) should be added in, Whitmania pigra Whitman and W. acranulata Whitma should be temporarily reserved, and H. pulchra Song, P. nanjingensis sp. Nov. , and P. hubeiensis Yang should be considered.
