Objective To evaluate the potential relationship between isoforms of BRCA1 associated RING domain 1 ( BARD1 ) and the pathophysiologic markers of sporadic breast carcinoma of female Han ethnic group. Methods The expression of BARD1 isoforms in 39 breast carcinomatous tissue, 12paracancerous-normal breast tissue and 7 controlled normal breast tissue was detected by reverse transcription polymerase chain reaction (RT-PCR) and then cloned and sequenced.The difference of isoforms expression and their clinical significance were analyzed. Results There were four transcriptive products of BARD1 found in all these candidates,named full lenth,isoform γ,isoform δ and isoform e.The positive rate of isoform γ and δ was higher in carcinomatous tissues than in paracancerous-normal tissues and normal breast tissue in healthy women ( P < 0.05 ). Carcinomatous tissue expressed more kinds of isoforms.There was significant difference between carcinomatous tissue and paranormal/nomal tissue ( P =0.0075 ).There was significant correlation between isoform ε positive and poor prognosis factors such as poorly differentiation,HER2 positive,poor pathologic type and larger breast cancer lumps(P < 0.05 ). Conclusions There are significant differences in the expression of BARD1 isoforms among different kinds breast tissues in the female Han ethnic group.Positive isoform ε may predict poor prognosis of breast carcinoma in the female Han ethnic group.

OBJECTIVETo develop a mouse model to mimic the behavioral and neurochemical changes of Tourette syndrome (TS) by 1-(2, 5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI) induction and to investigate the effects of fluoxetine and haloperidol on head twitch response (HTR) induced by DOI.
METHODS1) Preparation of mouse model of TS: Forty mice were randomly divided into experimental and control groups (n=20 each). DOI (1 mg/kg) was administered by peritoneal injection in the experimental group. The control group was injected with normal saline. The levels of dopamine (DA) and homovanillic acid (HVA), the metabolite of DA, in both groups were measured by high performance liquid chromatography and electrochemical detection. 2) Effects of fluoxetine and haloperidol on HTR: Eighty mice were randomly administered with either fluoxetine (2 mg/kg), haloperidol (0.8 mg/kg), fluoxetine + haloperidol or normal saline. DOI (1 mg/kg) was peritoneally injected 20 minutes later (acute trial) or 18-20 hrs after a 21 days injection of fluoxetine or haloperidol (chronic trial). The frequency of DOI induced HTR was observed immediately after DOI injection.
RESULTSThe levels of DA and HVA in the experimental group were significantly lower than those in the control group (DA: 45.00 +/-11.24 ng/mg vs 58.16 +/-14.51 ng/mg; HVA:10.54 +/-1.86 ng/mg vs 12.82 +/-2.66 ng/mg). In both acute and chronic trials, the frequency of DOI-induced HTR decreased significantly in mice administered with haloperidol alone or together with fluoxetine (P < 0.05), but it did not change significantly in mice administered with fluoxetine alone compared with the normal saline group.
CONCLUSIONSThe levels of DA and HVA are reduced in mice with DOI-induced HTR. DOI-induced mouse mode of HTR can mimic the neurochemical and behavioral changes of TS paritially. Haloperidol can inhibit DOI-induced HTR in mice, but fluoxetine can not.

OBJECTIVEIn the present study, using paeonol as model drug, a new sealed-control temperature method of preparing inclusion complex was developed, the effects of heating temperature, heating time, and crystallinity of beta-cyclodextrin (beta-CD) on formation of inclusion complex and release of the drug were investigated.
METHODA physical mixture of paeonol and beta-CD was sealed in a container, and heated at the desired temperature for the specified time. The inclusion complex of paeonol and beta-CD was confirmed by IR spectrum and powder X-ray diffraction.
RESULTThe results indicated that the inclusion complex formation of paeonol beta-CD by sealed-control temperature method was affected by heating temperature, heating time, and crystallinity of beta-CD. The inclusion complex was able to inhibit sublimation of paeonol, and dissolution rate of paeonol was increased when the paeonol was included by beta-CD.
CONCLUSIONPreparation of inclusion complex was simple and quick by sealed-control temperature method.

Objective To characterize the immunogenicity in gene immunization of the conserved regions of hepatitis C virus(HCV) based on different delivery strategies. Methods We first constructed a novel DNA vaccine encoding a fusion gene(from partial NS3 and Core) of HCV. Then we compared different protocols based on naked DNA injection twice or DNA injection with gene electrotransfer(GET) in BALB/c mice. The immune response was measured by antibody ELISA and by IFN-gamma ELISPOT. Results Our data showed that a protocol based on intradermally injection of DNA with optimal GET induced the strongest humoral and cellular immunity, and DNA with GET induced a substantially higher anti-NS3/Core T cell re-spoase than naked DNA injection. Conclusion Our data suggest that DNA vaccines encoding NS3/Core fu-sion protein of HCV immunized by the present strategy could merit further study in the context of future prophylactic and therapeutic HCV T cell based vaccines.
