Objective To investigate the diagnostic value and clinical implications of low hemoglobin density(LHD%)in the pa-tients with cervical carcinoma complicating iron deficiency anemia(IDA).Methods The iron metabolism indexes and whole blood cell parameters were detected in 148 patients with cervical carcinomas.LHD% was calculated.The results were compared with that in the healthy group and the hysteromyoma complicating IDA group.Results LHD% was(63 ±30)% in the cervical carcinoma complicating IDA group and(32±15)% in the cervical carcinoma complicating iron deficient erythropoiesis(IDE)group,which were higher than(7±6)% in the healthy group,(22 ±21)% in the cervical carcinoma non-iron deficiency group and(16 ±10)% in the cervical carcinoma non-anemia group(P <0.05 ).And which had no statistical difference between the hysteromyoma complicating IDA group and the cervical carcinoma complicating IDA group(P >0.05 ).Conclusion The new RBC parameter LHD% has the reference value in the diagnosis of cervical carcinoma complicating IDA.The LHD% increase may prompt cervical carcinoma com-plicating IDA.

A 35-year-old woman patient,complained of intermittent pain in the left flank for a week.Abdominal ultrasound and computed tomography scan revealed a left renal mass.Nephrectomy was performed,and a final diagnosis of adult Wilms' tumor was made based on histopathology and immunohistology.Chemotherapy was conducted for 4 times with dactinomycin D,vincristine and doxorubicin after surgery.At the time of the last recheck,the patient was alive with no evidence of disease.Adult Wilms' tumor is the exceptional malignant renal tumor.Only 1%-2% of Wilms' tumor is diagnosed in adult patients.Because of unspecific tumor symptoms in adults,the diagnosis is frequently made by histology.The diagnosis of adult Wilms' tumor is difficult to make preoperatively because diagnostic imaging only confirms the presence of a renal mass.Stage and histology are the clinical factors guiding the selection of postsurgical treatment and prognosis.Having retrospected 6 cases of adult Wilms' tumor between 1950 and 2007 and reviewed related reports,we conclude that the proper strategies of adjuvant treatment as applied to childhood Wilms' tumor patients after surgery can conspicuously improve the outcome in adult patients.

Objective To investigate the effect of mycobacterium tuberculosis heat shock protein 70(TB .HSP70) as an adjuvant carrier on stimulating hepatitis B virus (HBV) core antigen(HBcAg)specific immune response to an accompanying cytotoxic T lym-phocytes epitope peptide from HBV core antigen in vitro .Methods Recombinant proteins HSP70(P1)、HSP70-HBcAg(18-27) (P2)、HSP70-PreS2B (18-24)-PreS2Th(37-53)-HBcAg(18-27)(P3) were expressed in methylotropic yeast Pichia pastoris GS115 . The expression of recombinant proteins was identified by SDS-PAGE and Western blot .The effect of recombinant proteins on den-dritic cell and lymphocytes of chronic HBV infection volunteers was investigated in vitro .The maturation of dendritic cell was meas-ured by flow cytometry ;the secretion of Th1 cytokines such as IL-12p70 ,IL-1β,TNF-αand IFN-γ was measured by ELISA ;the proliferation of lymphocytes was measured by TdR-3H ;the HBV-spesific cytotoxic activity was measured by the classic 51 Cr .Re-sults The recombinant proteins (P1 ,P2 ,P3) were constructed successfully .P1 ,P2 ,P3 could activate dendritic cell from chronic HBV infection volunteers by upregulation CD1a ,CD40 ,CD86 and production Th1 cytokines such as IL-12p70 ,IL-1β and TNF-α. Especially P3 could better induce autologous T cells to generate HBV specific cytotoxic T lymphocytes response ,activate the prolif-eration of lymphocytes and release IFN-γeffectively .However ,the recombinant HSP70 showed no target cell killing and could not induce immune response effectively .Conclusion TB .HSP70 can be used as an adjuvant carrier to stimulate HBV specific immune response to an accompanying cytotoxic T lymphocytes epitope peptide from HBV core antigen ,and enhance immunogenicity of the cytotoxic T lymphocytes epitope peptide .The P3 with B-and T-epitope can activate the HBV specific immune response effectively .

Objective:To prepare sirolimus ( SRL) dropping pills to improve SRL solubility and dissolution. Methods:The base of SRL dropping pills was screened. The optimal formula and preparation process were also optimized by orthogonal design. The equi-librium solubility, hygroscopicity and drug release in vitro of SRL dropping pills were studied. Results: PEG6000 was chosen as the base. The optimal preparation conditions of SRL dropping pills were as follows: the ratio of SRL and base was 1∶10, the dropping speed was 65 drops/min, the dropping temperature was 95℃ and the temperature of cooling solvent was 5℃. The equilibrium solubili-ty of SRL dropping pills in different solvents was increased significantly compared with that of SRL. The hygroscopicity of the dropping pills was notable. The drug release in vitro of SRL dropping pills was similar to that of the marketed tablets with quick and complete re-lease. Conclusion:SRL dropping pills exhibit increased solubility and improved dissolution, which are valuable to be studied further.

To obtain active hFKBP52 protein for screening novel neu rotrophic drugs. Semi-nested and overlap PCR and affinity chromatography were u sed. hFKBP52 gene was cloned successfully from human fetal brain cDNA library, a nd then highly expressed (about 30%) as fusion protein in pET28a(+) vector syste m. The recombinant protein was purified as one band on SDS-PAGE. The purified h FKBP52 showed peptidyl-prolyl cis-trans isomerase (PPIase) activity, simil ar to the wild type.

Objective To validate the Partin table 1997,2001 and 2007 for their accuracy in predicting pathologic stage in Chinese prostate cancer patients.Methods From January 1997 to June 2007,109 consecutive patients with clinically localized prostate carcinoma underwent open retropubic or laparoscopic radical prostatectomies and met all inclusion criteria well enrolled.Receiver operating characteristic(ROC)analysis was performed tO test the predictive accuracy of organ confined disease (0CD),extraprostatic extension(EPE),seminal vesicle involvement(SVI)and lymph node involvement(LNI). Results OCD,EPE,SVl and LNl were noted in 70%,17%,13%and 0%of cases respectively.The area under curve(AUC)of ROC for Partin table 1997 was 0.727,0.654 and 0.811for 0CD.EPE and SVl respectively,and was 0.693,0.633 and 0.835 for Partin table 2001 and 0.669.0.611 and 0.778 for Partin table 2007.Conclusions Partin tables 1997,2001 and 2007 are able to accurately predict the pathologic feature of seminal vesicle involvement.However,only Partin table 1997 can more accurately predict organ confined disease in this external validation for Chinese patients.
