Purpose To study the radioactive purity and activity of 131I labeled human single chain variable fragments antibodies (scFv) against anaplastic thyroid carcinoma (ATC),and to explore its distribution and radioimmunoimaging characteristics in tumor bearing nude mice model in vivo so as to provide a new method for anaplastic thyroid carcinoma diagnosis and treatment.Materials and Methods The nude mice model bearing human anaplastic thyroid carcinoma was constructed.The chloramine T method was used to label scFv with 131I and the Sephadex G25M was used for purification of labeled scFv.Labeling rate was determined by trichloroacetic acid method;radiochemical purity,room temperature stability and serum stability were examined using paper chromatography.131I-scFv was injected via tail vein in mice,and the distribution of 131I-scFv in body tissues and organs was analyzed at 12,24,48,72 h after injection.Static SPECT imaging was performed at 12,24,48,72 h after injection to observe the intratumoral accumulation of radioactivity.The SPECT/CT image fusion was performed when the tumor tissues were clearly visible.Results 131I-scFv was purified,and the labeling rate was 91.64％;the radiochemical purity was (93.3 ±0.3)％.The radiochemical purity of 131l-scFv placed at room temperature and the serum for 1,6,12,24 h were all ＞90％.The radioactive distribution of 131I-scFv in tumor,liver,kidney,intestine and blood was high.SPECT imaging showed 131I-scFv was selectively concentrated in tumor tissue;the target/non-target ratio was the highest at 48 h,and the imaging was most satisfactory.Conclusion 131I-scFv can be successfully prepared.SPECT imaging of 131I-scFv in nude mice model is satisfactory,which lays the foundation for further research in ATC diagnosis and treatment.

Objectives To observe the genetic characteristics of chromosomes and the rates of implantation and pregnancy in couples of translocation carriers who undergo preimplantation genetic diagnosis (PGD) and to evaluate the significance of PGD in the treatment of translocation carriers. Methods Fluorescence in situ hybridization (FISH) was performed to analyze the embryos of 12 carriers of reciprocal translocation and 22 carriers of Robertsonian translocation. The results of diagnosis and the implantation and pregnancy rates were analyzed. Results A total of 253 embryos from 36 couples were retrieved and FISH was applied for the examination. The characteristics of chromosomes were diagnosed in 225 embryos and the rate of successful PGD was 88.9%. Fifty-eight embryos were found to have normal chromosome or balanced translocation and were transferred into the uterus. The rate of implantation was 36% (5/14) and 14% (6/44) and the rate of pregnancy was 4/9 and 26% (5/19) for carriers of Robertsonian translocation and reciprocal translocation, respectively. Conclusions The FISH-based PGD is effective in the diagnosis of Robertsonian translocation and reciprocal translocation of embryos. It provides the possibility of a high rate of implantation and pregnancy, and avoids recurrent abortion and unwilling termination of pregnancy.

Coronary artery disease (CAD) is one of the leading causes of death. Safflower attracts great attention owing to its anti-ischemia/reperfusion injury effect. Ninety-three patients with CAD were included and randomized into safflower treatment group, PCI group and control group. Low-dose dobutamine stress echocardiography (DSE) was performed to measure end-systolic volume (ESV), end-diastolic volume (EDV), left ventricular ejection fraction (LVEF) and wall motion score index (WMSI) to determine the recovery of hibernating myocardium and cardiac function in all patients before treatment and after 3-month follow-up. The study was to investigate the effects of safflower on hibernating myocardial revascularization and cardiac function. It was found that LVEF was significantly improved, while the ESV and WMSI were significantly reduced after 2-week treatment in safflower and PCI treatment groups. No significant differences were found between safflower and PCI treatment groups in ESV, EDV, WMSI and LVEF after treatment Safflower injection effectively improved hibernating myocardial function.

OBJECTIVETo investigate the effects of mouse preimplantation embryos on the expressions of DNA methyltransferase 1(Dnmt1) of mouse oviduct epithelial cells.

METHODSThe histological location of Dnmt1 protein was detected by immunohistochemical staining and the expression levels of Dnmt1 mRNA and protein in mouse oviduct were assayed by real-time reverse transcription-PCR(RT-PCR) and Western blotting in both pregnant and pseudopregnant mice at the 2-cell, 4-cell and 8-cell stages.

RESULTSThe expressions of Dnmt1 protein were mainly located in the epithelial cells of mouse oviduct. It was found that during all three stages, the expression levels of Dnmt1 mRNA in the epithelial cells of the pregnant mice were significantly lower than those in the pseudopregnant mice (P< 0.05), and the level of Dnmt1 protein expression in the pregnant mice was significantly decreased as compared with that in pseudopregnant mice at the 4-cell stage.

CONCLUSIONExpressions of both Dnmt1 mRNA and protein in the epithelial cells of mouse oviduct could be regulated by mouse preimplantation embryos, which might play an important role in the expression changes of some genes in oviduct epithelial cells during the preimplantation period.

BACKGROUND: Long-term complications of cesarean section include placenta praevia, placenta accreta, cesarean scar pregnancy and uterine rupture. These life-threatening complications in pregnant women maybe result from the defects of endometrium and uterine smooth muscle as well as poorly formed decidua in the scar of cesarean section. Mesenchymal stem cells have the function of repairing tissue injuries, and the amount of cells homing to the site of injury may affect the effect of tissue repair. OBJECTIVE: To explore the distribution and homing of bone marrow mesenchymal stem cells from male rats into rat models of cesarean section. METHODS: Bone marrow mesenchymal stem cells isolated from male rats in vitro were cultured and identified. Female Wistar rats were randomized into two groups: cesarean section group and control group. Rats in the cesarean section group were given intravenous administration of bone marrow mesenchymal stem cells from male rats via the tail vein on day 21 after cesarean section, and non-operative rats in the control groups were given the same amount of bone marrow mesenchymal stem cells from male rats after natural delivery. Rats in the two groups were sacrificed on days 7 and 28 after cell injection. The distribution of bone marrow mesenchymal stem cells from male rats in tissues (including heart, lungs, livers, kidneys, and uterine scar) was detected by measurement of the SRY mRNA level using SPY-PCR. RESULTS AND CONCLUSION: In the cesarean section group, the SRY gene was most abundant in the lung, followed by the liver and the kidney on day 7 after injection, although the distribution of SRY gene in the heart and uterine scar was low; on day 28 after injection, the levels of SRY gene in the lung, liver and kidney decreased (P < 0.05), but had no significant changes in the heart and uterine scar (P > 0.05). In the control group, the distribution of SRY gene was similar to that in the cesarean section group on both days 7 and 28 after injection, and the levels of SRY gene in the heart and uterus were low. These findings reveal that allogeneic bone marrow mesenchymal stem cells implanted mainly distribute in tissues with abundant blood flow, including lungs, livers and kidneys. And the cell number decreases gradually over time. Since the amount of implanted cells in the heart and uterus is very low, the change with time is not obvious. Cesarean section injury has no impact on the distribution of bone marrow mesenchymal stem cells in pregnant rats and there is of course no increase in the homing and colonization of bone marrow mesenchymal stem cells in a cesarean scar.

AIM:To explore the effect of sitagliptin (SLT) on cardiomyocyte pyroptosis induced by type 2 dia-betes mellitus (T2DM) and the underlying mechanism. METHODS:The T2DM rat model was established by high-fat diet and intraperitoneal injection of streptozotocin (35 mg/kg). The model rats were treated with SLT at 3, 10 and 30 mg/kg and nicotinamide [NAM; an non-specific inhibitor of sirtuin (SIRT) family] at 500 mg/kg for 4 weeks. Fasting blood glu-cose was measured, and the tissue proteins were determined by the methods of Western blot and immunochemistry. RE-SULTS:Compared with control group, the pyroptosis of cardiomyocytes and NLRP3 expression were significantly induced, while the protein level of SIRT3 was downregulated by T2DM (P<0.05). SLT inhibited the pyrpotosis of diabetic rat car-diomyocytes, downregulated the expression of NLRP3, and upregulated the expression of SIRT3 in a dose-dependent man-ner (P<0.05). All the function of SLT (30 mg/kg) was reversed by the treatment with NAM (500 mg/kg). Compared with control group, the pyroptosis of cardiomyocytes and NLRP3 expression were significantly induced, while the protein level of SIRT3 was not regulated by NAM (500 mg/kg). CONCLUSION:SLT exerts the inhibitory effect on the pyropto-sis of cardiomyocytes induced by diabetes, and the mechanism is related to the SIRT3/NLRP3 signaling pathway.
