4 weeks of arrested embryos.The AAH expression was found to have the similar result as HIF-1?'s.Conclusions The expression level of HIF-1? and AAH in villi of missed abortion patients is much lower than that of normal early pregnant women.HIF-1? and AAH have a function of supporting normal pregnancy,so their low expression may be an important cause of missed abortion.

Objective To explore the treatment of hemangioma associated with thrombopenia(Kasabach-Merritte syndrome,KMS) in infant.Methods The clinical manifestation and the therapy of 14 cases patients with KMS in hospital from 2003 to 2006 were collected ang analyzed,the 400 g/L urea(manufactured by ourself)combined with methylprednisolone local injection were used and followed 0.5 to 1.0 year.Results Two in 14 cases were emergency exairesis,7 cases were recurred for several times,12 cases were cured,1 case was improved,1 case was loss the connection.Conclusions It is an ideal therapy method to use the urea combined with glucocorticoid to treat infancy KMS,little trauma,definite effective,low side effect,high cure rate.

OBJECTIVETo research the effects of Guizhi Fuling capsule on sex hormones levels in blood serum and breast issue morphology of hyperplasia of mammary glands model rats.

METHODThe unpregnancy SD rat models of hyperplasia of mammary glands were established by injecting 0.5 mg x kg(-1) benzoate estradiol. After five weeks doses,the effects of Guizhi Fuling capsule 2.0, 1.0, 0.5 g x kg(-1) and Rupixiao tablet 0.5 g x kg(-1) on the changes of papilla diameter, height and breast issue morphology of the naimal models were explored, and sex hormones levels in blood serum were measured.

RESULTGuizhi Fuling capsule can inhibitnipple swell, improve breast tissue morphology pathological profiles of the animal models, and decrease oestradiol (E2) level and increase progesterone (P) level in blood serum.

CONCLUSIONThese results suggested that Guizhi Fuling capsule could, improve mammary gland pathological profiles. Regulating sex hormone levels may be its important mechanism for treatment of hyperplasia of mammary glands.

Traditional Chinese medicine (TCM) reference standards plays an important role in the quality control of Chinese herbal pieces. This paper overviewed the development of TCM reference standards. By analyzing the 2010 edition of Chinese pharmacopoeia, the application of TCM reference standards in the quality control of Chinese herbal pieces was summarized, and the problems exiting in the system were put forward. In the process of improving the quality control level of Chinese herbal pieces, various kinds of advanced methods and technology should be used to research the characteristic reference standards of Chinese herbal pieces, more and more reasonable reference standards should be introduced in the quality control system of Chinese herbal pieces. This article discussed the solutions in the aspect of TCM reference standards, and future development of quality control on Chinese herbal pieces is prospected.

Objective To investigate the dynamic distribution changes of fungi responsible for the deep infection and antifungal susceptibility to provide a basis for the empirical antifungal treatment.Methods Medical records were reviewed from cases suspectedof deep fungal infection at our hospital from January 1998 to December 2004.3122 isolates of 13 species were analyzed with SPSSll.0.Etest was used for the antifungal susceptibility test.Results Candida albicans was the most commonly isolated organism,while the prevalence of Candida albicans decreased(76.3% vs 66.8%,x~2=34.33,P

Essential hypertension (EH) is a complex multifactorial disorder with genetic and environmental factors contributing to its prevalence. The genetic features have been revealed from the significant familial aggregation and the consistency among twins. Therefore, identification of EH susceptibility genes will be helpful to understand the pathophysiology of the disease, identify populations with potential risks of developing the disease, and select antihypertensive drugs. The present article introduces the search strategies of EH susceptibility genes and some genetic variants related to EH; meanwhile, it tries to analyze the difficulties and the role for samples in identifying susceptibility genes to EH.

OBJECTIVETo investigate the influence of pyrrolidine dithiocarbamate (PDTC) on the expression of transforming growth factor beta(1) (TGF-beta(1)), matrix metalloproteinase-2 (MMP-2) and tissue inhibitor-1 of metalloproteinase (TIMP-1) in rats with pulmonary damage induced by paraquat (PQ).

METHODSFifty-four healthy male SD rats were randomly assigned into the control group (normal saline), the PQ-treatment groups (4 groups) and the PDTC treatment groups (4 groups). Except the rats in the control group, the rats in the PQ group were gavaged only with 40 mg/kg PQ, and PDTC group with 40 mg/kg PQ plus immediate injection 120 mg/kg PDTC (i.p). On the 3rd, the 7th, the 14th and 28th day after treatments, one group rats of each treatments were sacrificed and lung and blood samples were collected. The level of TGF-beta(1) protein in the plasma, the mRNA expression of TGF-beta(1), MMP-2 and TIMP-1 were evaluated using RT-PCR and real-time quantitative PCR, while pathological changes of lung were examined under optical microscope and electrical microscope.

RESULTSThe TGF-beta(1) protein, TGF-beta(1) and MMP-2 mRNA expression were increased significantly in the earlier stage and then decreased after PQ administration (P < 0.05 or P < 0.01), while the mRNA level of TIMP-1 was augmented continuously (P < 0.01) throughout the study compared to the control group. In comparison with the PQ group, in the PDTC treatment group, the TGF-beta(1) mRNA expression on the 3rd and the 14th day, 0.54 +/- 0.08 and 0.72 +/- 0.04 respectively, the MMP-2 mRNA expression on the 7th and 14th day, 1.62 +/- 0.50 and 1.97 +/- 0.34 respective-ly, and the TIMP-1 mRNA on the 7th and 21st day, 1.79 +/- 0.21 and 2.00 +/- 0.34 respectively, were significantly decreased (P < 0.05 or P < 0.01).

CONCLUSIONPDTC could attenuate paraquat-induced up-regulation of TGF-beta(1) and its mRNA expression, MMP-2 and TIMP-1 mRNA levels, which indicates that PDTC may exert its protective effects on paraquat-induced pulmonary damage by alleviating the earlier inflammation damage and adjust-ing the balance between MMPs and TIMPs. However, further studies are still warranted to investigate and clarify the underlying mechanisms involved in this complicated process.

OBJECTIVE: To explore the diagnostic value of 2-dimentional ultrasonography and color Doppler flow imaging (CDFI) in primary bone tumor. METHODS: The hemodynamic parameters such as systolic maximum velocity (Vmax), diastolic minimum velocity (Vmin), resistance index (RI), and pulsatility index (PI) of intratumoral folw in 93 patients with primary bone tumors proved by histopathology were studied using 2-dimentional ultrasonography and CDFI techniques. RESULTS: The bone destruction periosteum response and soft tissue mass were essentially revealed with 2-dimentional ultrasonography techniques. The intratumoral flow features were clearly shown by CDFI. The Vmax and Vmin in malignant bone tumor were significantly higher than those in benign one (P < 0.01). RI and PI in malignant bone tumor were lower than those in benign one (P < 0.01). CONCLUSION Observing the features of bone tumor and hemodynamic parameters by 2-dimentional ultrasonography and CDFI has a great clinical value in diagnosing primary bone tumor and distinguishing the malignant and benign bone tumors.
