Objective To study the clinical, histological and immunohistochemical features of breast hamartomas. Methods The specimens were fixed in 10% formalin and embedded in paraffin. The sections were stained with hematoxylin and eosin for histological diagnosis. SP technique was used in the immunohistochemical study.Results We have 8 cases of breast hamartomas with well defined borders microscopically, histologically composed of ducts, lobules, fibrous stroma, adipose tissue. None of the epithelial elements showed any evidence of atypia. Immunohistochemical analysis showed that there was a variable number of epithelial cells showing a nuclear staining for estrogen receptor(ER) in all cases.Conclution Mammary hamartomas are benign tumor like lesions, histologically dissimillar from other breast tumors. It is affected by hormonal factors. The diagnosis is achieved by combining clinical, radiological and pathologic results.

Objective To evaluate the rate and types of human papillomavirus (HPV) in vulvar intraepithelial neoplasia (VIN).Methods We detected HPV DNA in 67 lesion tissues collected from 40 VIN patients with PCR based reverse line blot hybridization and DNA sequencing. The PCR using GP5/GP6 primers in HPV L1 region resulted in a 150-bp fragment. When the PCR did not amplify the target DNA,another PCR using SPF1/SPF2 primers was performed to amplify the 65-bp fragment.Results HPV DNA amplified with primers GP5/GP6 was positive in 52.2% (35/67) of the lesions. Of the 32 negative lesions,26 (81.2%) were positive for HPV DNA amplified with SPF1/SPF2 primers. The total positive rate was 91.0% (61/67). Ninety percent of the HPV belonged to high risk types. Sequencing data showed that the genotypes of 31 mono-infection lesions were the same as those of the reverse line blot results,yet the sequences in 4 multi-infection samples could not be determined. Of the 26 SPF PCR products,24 could be sequenced. 80.6% (25/31) patients with multiple lesions displayed the same genotype,suggesting HPV in the different lesions from the same patient was monoclonal.Conclusion The high risk type of HPV is associated with vulvar intraepithelial neoplasia and may play an important role in the development of invasive vulvar carcinoma.

RESULTS:The varieties and amount of TCM injections for blood-activating and stasis-resolving both occupied the first place. 22% inpatients used two or more TCM injections at the same time. The proportion of overdose use of TCM injections reached 54.55%. The type of unreasonable drug use mainly included drug use against differentiation of syndromes,super indications drugs and solvent error. Combined use of TCM injections with same ef-fect accounted for 20.45% of combined use of TCM injections. CONCLUSIONS:It is effective means to improve rational drug use that great impertance paid for clinical use of TCM injections.

Background and purpose:Drug resistance is a major cause of failure in lung cancer chemotherapy. This study aimed to investigate the effect of YAP on doxorubicin resistance in lung cancer and its underlying mechanism. Methods:Doxorubicin resistant lung cancer cell clones were established from parental sensitive cancer PC9 cell line via in vitroinduction, and the expression of YAP was analyzed. YAP was down-regulated via shRNA to different levels. MTS assay was employed to determine cell proliferation and drug sensitivity. Flow cytometry was used to determine cell cycle distribution, apoptosis and uptake of Rh-123. Western blot and quantitative real-time polymerase chain reaction (QRT-PCR) assay were used to determine the expression of ABCB1, ABCC1, p53, Runx2, ITGB2 and ErbB4. The phosphory-lation of serine/threonine kinase (AKT) was determined as well.Results:Doxorubicin resistant PC9/Adr cell clone was obtained with over-expressed YAP. Expression of YAP in PC9/Adr cells was down-regulated to different levels via shR-NA. After YAP silencing, cell proliferation was reduced, while sensitivity to doxorubicin was increased. The cell cycle was significantly halted by G0/G1 phase. Doxorubicin induced-apoptotic rate and cellular uptake of Rh-123 were increased,with positive correlation to YAP silencing level. Western blot and QRT-PCR results showed that after YAP silencing, ABCB1, ABCC1, Runx2, ITGB2, and ErbB4 proteins were down-regulated, while the expression of p53 was up-regulated. Phosphorylation of AKT was inhibited as well.Conclusion:Over-expression of YAP is involved in doxorubicin resistance in PC9/Adr cell line. Silencing of YAP could restore doxorubicin sensitivity. The mechanism involves regulation of drug resistance-related genes and promotion of apoptosis.

Batifiban, a synthetic cyclic peptide, is a potent platelet glycoprotein GPIIb/IIIa antagonist which may be useful in the treatment and prevention of acute coronary syndromes. The pharmacokinetics and pharmacodymanic (inhibition of platelet aggregation) effects, and tolerability of batifiban were investigated in healthy subjects following single bolus injection with doses of 55, 110, or 220 microg/kg, or multiple doses of an bolus followed intravenous infusion for 24 h (180 microg/kg plus 2.0 microg/min.kg, and 220 microg/kg plus 2.5 microg/min.kg) in this phase I clinical trial. Plasma levels of batifiban and areas under the curve were found to be proportional to doses. Batifiban was rapidly eliminated with a half-life of approximately 2.5 h. Significant differences were noted for plasma levels of batifiban and areas under the curve between males and females. No significant differences in the terminal half-life were found between males and females. Batifiban reversibly inhibited ex vivo platelet aggregation in a dose- and concentration-dependent manner, consistent with its mechanism as a GPIIb/IIIa antagonist. Single and multiple intravenous doses of batifiban were found to be safe and well tolerated in healthy subjects. These results support a bolus injection plus intravenous infusion regimen of batifiban for the treatment and prevention of acute coronary syndromes.
