Objective To describe the diagnosis and preoperation evaluation of pancreatic carcinoma with spiral CT three-phase contrastenhanced scan and post-processing.Methods Three-phase helical CT enhanced scan and post-processing images of 41 patients with pancreatic carcinoma were retrospectively analyzed,including the location,size,characteristic of tumor and peripancreatic blood vessels,the results were compared with that of surgery.Results Low degree of enhancement of pancreatic carcinoma in pancreatic phase was showed compared with parenchymal phase.There was significant difference in density between focus and normal pancreas,the lesions were showed clearly.In comparison with surgical results,the diagnostic accuracy of CT was 80.7% and the accurate rate in evaluating the metastasis was 75.8%.Conclusion Three-phase helical CT enhanced scan and postprocessing are of great value in diagnosis of pancreatic carcinoma and it is helpful in choosing the treatment program preoperatively and assessing the respectability of tumors.

OBJECTIVE:To establish an HPLC method for the content determination of oxaliplatin in Oxaliplatin liposome. METHODS:The separation was performed on Hypersil C18(250 mm?4.6 mm,5 ?m) column with methanol-water(5 ∶ 95,V/V) as mobile phase at flow rate of 1.0 mL?min-1. The detection wavelength was set at 250 nm and column temperature was 30 ℃. RESULTS:The linear range of oxaliplatin was 12.2～122.0 ?g.mL-1(n=5,r=0.999 9) with an average recovery of 98.58%(RSD=1.83%). The limit of detection(LOD) was 97.6 ng?mL-1. CONCLUSION:The method is simple,sensitive and accurate for the content determination of oxaliplatin in Oxaliplatin liposome.

Objective:To compare the effect of laparoscopic uterine isthmus cerclage and transvaginal uterine isthmus cerclage in the treatment of cervical incompetence at non pregnant condition.Methods:A total of 63 patients with cervical incompetence from May 2013 to May 2015 in our hospital were enrolled in the retrospective analysis,all the enrolled patients had naturally conceived single birth with complete data after laparoscopic uterine isthmus cerclage or transvaginal uterine isthmus cerclage and were divided into two groups according to two different surgical methods for uterine isthmus cerclage to compare the clinical effect.30 patients treated with laparoscopic uterine isthmus cerclage were,in the research group and the other 33 patients treated with transvaginal uterine isthmus cerclage were in the control group.Results:The treatment success rate of research group (96.67％) was significantly higher than that of the control group(51.52％) (P ＜ 0.05).The research group had got a longer average pregnancy period than control group (P ＜ 0.05).Postoperative abortion rate (3.33％) and preterm birth rate(10.00％) of research group were obviously lower than the control group (48.48％,30.30％)(P＜0.05).The term infant rate of research group (86.67％) was higher than control group (21.21％) (P ＜0.05).The operation time((37.27 ± 1.93 min) and hospital stay(5.17 ±0.38 d) of the research group were less than the control group(P＜0.05).The bleeding amount in surgery of research group(13.13 ±1.57ml) was significantly lower than the control group(31.61 ± 1.87 ml) (P ＜ 0.05).The complication rate of observation group was 0,and the control group was 18.18％.The difference was significant(P ＜ 0.05).Conclusions:Laparoscopic uterine isthmus cerclage in treatment of cervical imcompetence at non pregnant condition has better clinical effect than transvaginal uterine isthmus cerclage.It has higher security and feasibility.It is worth clinically promoting.

Objective To investigate the effects of electroacupuncture of different stimulation waveforms on the 5-hydroxytryptamine (5-HT), glutamic acid (Glu) and gamma-aminobutyric acid (CABA) contents of the hypothalamus in rats with para-chlorophenylalanine (PCPA)-induced insomnia and explore the difference in the effects and the mechanism of its action. Methods Fifty SD rats were randomly allocated to a normal group of 10 rats, a model group of 10 rats and an electroacupuncture group of 30 rats. The electroacupuncture group was then randomly divided to electroacupuncture groups 1, 2 and 3, 10 rats each. A rat model of insomnia was made using PCPA in all groups of rats except the normal group. All the electroacupuncture groups received electroacupuncture treatment. Of them, electroacupuncture group 1 received sparse wave treatment; electroacupuncture group 2, dense wave treatment;electroacupuncture group 3, sparse-dense wave treatment. After 6 days of treatment, every group of rats was sacrificed by cervical dislocation. The 5-HT, Glu and CABA contents of the hypothalamus were measured by enzyme-linked immunosorbent assay. Results The 5-HT content of the brain decreased significantly in the model group of rats compared with the blank group (P<0.01) and increased significantly in electroacupuncture group 3 of rats compared with the model group (P<0.01). There was a statistically significant difference in brain 5-HT content between electroacupuncture group 2 or 3 of rats and electroacupuncture group 1 (P<0.05,P<0.01) and between electroacupuncture groups 3 and 2 of rats (P<0.01). The Glu and CABA contents of the cerebral cortex and the ratio of Glu/CABA increased significantly in the model group of rats compared with the blank group (both P<0.01) and decreased significantly in electroacupuncture group 3 of rats compared with the model group (both P<0.01). There were statistically significant differences in the Glu and CABA contents of the cerebral cortex between electroacupuncture group 2 or 3 of rats and electroacupuncture group 1 ((P<0.05,P<0.01) and between electroacupuncture groups 3 and 2 of rats (P<0.01). Conclusions Electroacupuncture can regulate hypothalamic monoamine neurotransmitter 5-HT content and amino acid neurotransmitters Glu and CABA contents and reduce intracerebral amino acid toxicity to produce a therapeutic effect on insomnia in insomnia rats. The therapeutic effect of sparse wave electroacupuncture is superior to that of dense wave or sparse-dense wave electroacupuncture.

Objective To explore the clinical value of 18F-FDG PET/CT in the diagnosis of cardiac neoplasm.Methods Between January 2007 and December 2011,18F-FDG PET/CT was performed in 8649 patients in our hospital,and 14 (0.16％ ; 11 males,3 females,average age 46.9 (35-68) years) patients were diagnosed with cardiac neoplasm.18F-FDG PET/CT data of those 14 patients were retrospectively analyzed.Final diagnoses were confirmed by either histopathology (n =5) or follow-up (n =9).Results Accurate tumor localization and diagnoses were made by 18 F-FDG PET/CT in all 14 patients.Among them,13 were malignant (2(14.3％,2/14) primary and 11(78.6％,11/14) metastatic tumors (8 HCC,2 lung cancer,1 esophageal cancer) ; SUVmax 3.2-10.7) and 1 (7.1％,1/14) was benign (myxoma).Conclusion 18F-FDG PET/CT is useful for the detection and staging of primary malignant and metastatic cardiac neoplasms.

0.05). Conclusion Enough high-purified LECs can be isolated by collagenase digestion procedure followed by immunomagnetic beads sorting. Post-thawed endothelial cells are proved to have high vitality and growth potential in vitro without significant morphological changes. Cryopreserved LECs may serve as a cell choice for research of lymphangiogenesis and lymphatic patterning.

AIM: To explore the skills and characteristics of corneal neovascular model in rat induced by micropocket assay. ·METHODS: Nine eyes of nine Sprague-Dawley rats were studied. Pellets made of vascular endothelial growth factor (VEGF), poly-2-hydroxylethylmethacrylate and sucralfate were implanted into the corneal stroma nocloser than 1mm from the limbus. Biomicroscopic features of corneal neovascular were observed on 1,3, 5, 7th day after the implantation. ·RESULTS: On day 1 after operation, the limbal vessels were dilated, with no angiogenesis appeared. On day 3, angiogenesis began to invade peri-cornea with a brush shape, the area of CNV was (2.23±0.59) mm2. On day 5, new vessels reached the lower margin of pellet densely, the area of CNVwas (6.81±1.35)mm2. On day 7, new vessels continued to elongate, parts of them extended as loops toward the pellet, the area of CNV was (8.92± 1.79)mm2. Neither hyphema or other complications occurred.·CONCLUSION: Corneal neovascular induced by micropocket assay in rat grows steadily, with no complication, and is suitable for quantitative researches.
