Objective To evaluate the value of transvaginal ultrasonography in diagnosis of ovarian pregnancy. Methods Ultrasound features of 21 cases of ovarian pregnancy were retrospectively studied in comparison with those of surgery and pathology. Results All the cases were diagnosed extrauterine pregnancy and suggested 3 cases with the lesion localizing inside the ovary,3 cases superficial to the ovary, 1 case unclear localization and 2 cases misdiagnosed as tubal ectopic pregnancy, the correct localization was made in 66.7 % of 9 unruptured cases by endovaginal sonography. Twelve ruptured cases were unclear localization by endovaginal sonography. The sonographical appearance of ovarian pregnancies showed normal or little bigger uterus, empty uterine cavity, a gestational sac or inhomogenous strong echoes interior or superior to the ovary, or complex mass in the adnexal area with abundant free fluid in the pelvic. Conclusions Transvaginal sonography is of diagnostic value in ovarian unruptured pregnancy.

To understand molecular modules related to polyunsaturated fatty acids (PUFA) synthesis and eventually produce PUFA at high efficiency, we developed a protein complex analysis technology in Synechocystis sp. PCC 6803, and applied it to identify possible partner proteins interacting with the key enzymes that catalyze PUFA biosynthesis. We first constructed a recombinant expression of protein of slr1609 encoding the fatty acid activation enzyme, by fusing 3xFLAG tag with the target protein. Then we verified its expression by Western blotting targeting 3xFLAG tag. To maximize purification of Slr1609 protein complex, we optimized the protein expression conditions of Slr1609 in Synechocystis in a 5 L fermenter by monitoring its gene expression using RT-qPCR. The purification of the Slr1609 protein complexes was demonstrated by a Native-PAGE analysis. Finally, LC-MS/MS proteomic analysis allowed identification of the possible partner proteins interacting with Slr1609.

Objective To study and evaluate the therapeutic safety and effect of frequency-doubled-double-pulse laser(FREDDY)lithotripsy for treating upper urinary calculi combined with acute renal failure.Methods The clinical data of 32 cases treated by frequency-doubled-double-pulse laser(FREDDY)lithotripsy were retrospectively analyzed.Results After the operation the serum BUN and Cr levels in the patients got close or returned to normal and the free rate of the stones was up to 90.6%(29/32).Conclusions The ureteroscopic frequency-doubled-double-pulse laser(FREDDY)lithotripsy has the advantage of safety,high efficiency and less trauma for treating the upper urinary tract obstruction combined with acute renal failure.It can also deal with the bilateral ureteral stones at one time.It can be the first choice when the condition is proper.

AIM: To study the basic mechanism of transcriptional regulation,NKX3.1 gene promoter was cloned and its promoter activities in prostate cancer cell lines and other cancer cell lines were tested.METHODS:(1.04 kb)-promoter fragment of NKX3.1 gene was obtained by PCR and cloned into pGL_3-basic and pEGFP-1 that are promoter-less reporter vectors to examine its promoter activity driving the reporter gene transcription.The promoter activity was determined by dual-luciferase reporter assay and the expression of GFP reporter observed under fluorescence microscope.RESULTS: The sequence of the cloned(1.04 kb) promoter proved to be correct by DNA sequencing.The dual-luciferase reporter assay(M1/M2) showed that the promoter activity in LNCaP cell transfected with pGL_3-(1.04 kb) promoter was about 1.5-fold higher than that of pGL_3-control transfection and 50-fold higher than that of pGL_3-basic transfection.To investigate the 1.04 kb-promoter activity in different tumor cell lines,the constructed pGL_3-(1.04 kb) promoter and pEGFP-1.04 kb promoter were transfected into several cell lines,respectively.The results showed that the activity of(1.04 kb) promoter in LNCaP was highest among the tested cell lines.Multiple consensus sequence elements have been identified within the(1.04 kb) fragment using TRANSFAC database.Further experiments will be done to determine their founctions.CONCLUSION: Cloned 1.04 kb fragment upstream of NKX3.1 gene presented a strong promoter activity and its activity was highest in LNCaP cell among the tested tumor cell lines.

AIM: To observe the effect of curcumin on the proliferation and apoptosis of prostate cancer cell line LNCap.METHODS: LNCap cells were treated with different doses(10 ?mol/L,20 ?mol/L,30 ?mol/L,40 ?mol/L) of curcumin and its effects were analyzed in cell growth and apoptosis by microscope,MTT colorimetric assay and flow cytometry.The expression of prostate specific antigen(PSA) was measured by AXSYM~(TM) system-chemical luciferase methods and expression of androgen receptor (AR) was detected by Western blotting.RESULTS: The results showed that curcumin inhibited the proliferation of LNCap cells.The cell growth was inhibited by curcumin in a dose dependent manner and the optimal dose and time was 40 ?mol/L,24 h.Curcumin induced apoptosis in LNCap cells,the most dramatic dose was 40(?mol/L) curcumin,at this dose the apoptosis rate was 9.23%. Curcumin inhibited the expression of PSA in LNCap cells and the most dramatic dose and time was 40 ?mol/L,24 h.The PSA in this group was 20% of the control group.Curcumin inhibited the expression of AR on prostate cancer cells.CONCLUSION: Curcumin decreases proliferation and induces apoptosis in LNCap cells in a dose-dependent manner.Curcumin also inhibites the expression of PSA and AR on LNCap cells.
