NK cell function was tested in 60 patients randomly selected with ad- vanced primary liver cancer(PLC)during interventional treatment.The patients were di- vided into three groups and treated with different regimens.In group 1(n=20),routinally using HAI(5-Fu 1000mg,CDDP 30mg)and HAE(Lipiodel 10～20ml,EAMC 50mg)in group 2,the treatment project is same as in group 1,but after the treatment,total 8g Natrii thiosulfas was administrated intravenously within 48 hours;in group 3,one week after treatment as in group 1,the patients received a-2b IFN injected subcutaneously at a dose of 10?10~6 IU,B.i.w,for more than 2 months.The results showed that:1.NK function in the patients with advanced PLC was 17.45?4.5% ,significantly lower than that in the nor- mal ones(21.39?3.58%);2.After the interventional treatment,the NK function of the patients were obviously decreased in group 1(13.58?3.14%),and in group 2(15.45?2. 69%),but increased in group 3(19.20?3.27%).The results suggested that conventional interventional treatment will affect NK cell function of patients with advanced PLC in some degree,and the effect can be reduced by injecting Natrii Thiosulfas i.v.,and administering IFN.

Objective To evaluate a new animal model of venous stenosis induced by local mechanical injury with the presence of surgical arteriovenous fistula (AVF).Methods Twelve arteriovenous (AV) fistulae were surgically formed between the carotid artery and internal jugular vein in six adult pigs, one on each side of the neck. Direct mechanical injury was made by crush injury with fingers or forceps to the jugular vein at the sites 1-2cm above and below the AV anastomosis. Angiographic follow up was performed at 3 and 6 weeks, and the animals were sacrificed. Fistulae and injured veins were harvested for histopathology. Results At angiography six AV anastomoses were patent without stenosis, five were stenosed and one had occluded. Eleven of twelve venous injury sites with open AV anastomosis and six of ten venous injury sites with AV anastomotic stenoses developed greater than 50% diameter stenosis. Dilation was found in the non injury segment of eight jugular veins. Stenoses were caused by neointimal hyperplasia as seen on histologic examination.Conclusions Neointimal venous stenosis can be induced by creation of a surgical AV fistula and local venous mechanical injury. This model may be used to study methods to reduce or inhibit neointimal hyperplasia, with particular reference to venous stenoses that occur in arteriovenous shunts created for dialysis access.

Objective To evaluate the safety and feasibility of portal CO 2-DSA with fine needle splenic puncture. Methods The splenic tails of seven adult white rabbits were exteriorized by laparotomy, and followed by a 25 gauge fine needle inserting about 1.0 cm into the splenic parenchyma. Portal CO 2-DSA was performed (2.0 ml/s, 10ml) and the images were evaluated. After removal of the needle, the puncture site was observed for bleeding till coagulation occurred. The spleen were taken for gross and histological examination. Results All the CO 2-DSA clearly showed the portal trunk with intrahepatic branches above 3～4 orders, the main splenic vein, and the main mesenteric veins with parts of its branches. CO 2 disappeared from the intrahepatic portal vein over 2～3 minutes. In one animal, the left renal vein and the inferior vena cava were also displayed by CO 2 through communication between splenic vein and renal vein. After removal of the needle, there was small amount of bleeding at the puncture site which ceased spontaneously over 3～5 minutes. In all animals, no extravasation of CO 2 at the puncture site, no subcapsular dissection or intrasplenic hematoma was observed. Microscopically, the splenic capsule appeared intact and there was no evidence of subcapsular hematoma formation.Conclusions Portal CO 2-DSA with fine needle splenic puncture is feasible, safe and efficient. In normal adult rabbit, CO 2 may help to visualize the left renal vein and inferior vena cava through communication between splenic and renal vein.

Objective To compare the clinical value of uterine submucosal myoma classification by two dimensional and three-dimensional contrast-enhanced ultrasonography and surgical pathologic results.Methods The imaging data of ultrasonographic hysterography including 2D and 3D of 124 patients with uterine submucosal myoma were retrospectively analyzed,and the results were compared with the surgical pathologic results.The diagnostic accuracy of uterine submucosal myoma classification and the operation success rate of uterine submucosal myoma for Ⅰ grade by ultrasonographic hysterography including 2D and 3D were compared.Results The patients were diagnosed pathologically with 0,Ⅰ and Ⅱ grade of uterine submucosal myoma in 26 cases,52 cases,68 cases,respectively.The patients were diagnosed by 2D ultrasonic sonohysterography with 0 grade,Ⅰ grade and Ⅱ grade of uterine submucosal myoma in 26 cases,62 cases,58 cases,respectively.The patients were diagnosed by 3D ultrasonic sonohysterography with 0,Ⅰ and Ⅱ grade of uterine submucous myoma in 26 cases,52 cases,68 cases,respectively.For pathological results as thegold standard,the diagnostic sensitivity,specificity and accuracy of uterine submucosal myoma for 0 grade by 2D and 3D ultrasonic sonohysterography were all 100.00％.The diagnostic sensitivity,specificity and accuracy of uterine submucosal myoma for Ⅰ and Ⅱ grade by 2D ultrasonic sonohysterography were 92.32％,79.46％,85.00％,respectively.The diagnostic sensitivity,specificity and accuracy of uterine submucosal myoma for Ⅰ and Ⅱ grade by 3D ultrasonic sonohysterography were 96.24％,88.24％,91.76％,respectively.There were significant differences in the diagnostic sensitivity,specificity and accuracy of submucosal myoma of uterus for Ⅰ and Ⅱ grade by 2 D and 3 D ultrasonic sonohysterography (x2 =3.21,2.78,2.17,2.33,all P ＜ 0.05).The patients diagnosed as uterine submucous myoma for 0 grade all underwent the hysteroscopic surgery for successful resection,while the patients with uterine submucous myoma for Ⅱ grade underwent laparoscopic surgery or open surgery.The operation success rates of uterine submucous myoma for Ⅰ grade by hysteroscopic surgery diagnosed by 2D and 3D ultrasonic sonohysterography were 75.81％,98.07％,respectively.The operation success rate of uterine submucous myoma for Ⅰ grade by hysteroscopic surgery diagnosed by 3D ultrasonic sonohysterography was significantly higher than that diagnosed by 2D ultrasonic sonohysterography (x2 =7.15,P ＜ 0.05).Conclusion The accuracy of uterine submucosal myoma classification by 3D ultrasonographic hysterography is better than 2D ultrasonographic hysterography.

Objective To evaluate the outcome of dorsal double locking compression plate (LCP) in treatment of stretched unstable distal radial fractures.Methods Fourteen cases of stretched unstable distal radial fractures were treated by reduction and internal fixation using straight or L-shaped anatomic LCP via dorsal approach.Wrist functional exercise was conducted immediately after operation.Follow up was made after operation to assess motion pain,functional score of wrist,and complication incidence at postoperative 12 weeks,24 weeks,and 1 year.Results Follow-up was lasted for 5-24 months.At postoperative 12 weeks,24 weeks and 1 year,mean visual analogue scale (VAS) was (1.88 ±0.26) points,(0.87 ± 0.14) points and (0.37 ± 0.06) points respectively and wrist functional score (Gartland-Werley score) was (6.45 ± 1.72) points,(2.73 ± 0.52) points and (2.10 ± 0.31) points respectively.According to Garfland-Werley score in the latest follow-up,the results were excellent in 10 cases,good in two,and fair in two.Besides,one case was combined with myotenositis of extensor pollicis longus muscle tendon and another case with myotenositis of extensor tendon.Conclusion Dorsal double LCP is one of the effective methods for stretched unstable distal radial fractures that can reconstruct anatomical structure of the wrist efficiently and attain satisfactory functional recovery,with no obvious pain.

Objective To investigate the characteristics of coronary vessel re-endothelialization after placement of drug-eluting stents (DES), and to provide clinical evidence for the double anti-platelet treatment. Methods Optical coherence tomography (OCT) was performed in 43 patients in 1 year after DES implantation. Characteristics of re-endothelialization and percentage of neointimal coverage of stent struts were evaluated by OCT. Results The rate of stent struts intimal coverage was 90.70%, and the remain was lack of endothelial coverage; The ratio of neointimal thickness (NIT) between 0-99, 100-199 and above 200 microns was 19.92%, 37.55% and 42.53%, respectively. The rate of neointimal coverage was higher and the degree of neointimal hy-perplasia was more extensive in patients with DM and in patients with ACS than those of patients without DM and of patients with stable angina pectoris. Conclusion One year after stent placement, most of the stent struts were covered with neointima and few struts obtained poor coverage of endothelial. DM and ACS may be impact factors for the progress of re-endothelialization after DES placement.

ObjectiveTo investigate the role of Notch1 gene in xenografted human cutaneous squamous cell (SCL-1) carcinoma. MethodsFifteen nude mice were divided into three groups, including untreated group(inoculated with SCL-1 cells treated with phosphate buffered saline), empty vector group (inoculated with SCL-1 cells transfected with empty vector) and Notch1 group(inoculated with SCL-1 cells transfected with Notch1 expression vector). All the mice were inoculated with SCL-1 cells(1 x 108/ml) of0.2 ml. Then, the growth of xenografted tumor was observed every other day. Fifteen days later, the mice were sacrificed, tumor tissue was dissected and subjected to terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay for the detection of cell apoptosis, reverse-transcription(RT)-PCR and Western blot for the examination of mRNA and protein expressions of Notch1, bcl-2 and bax, respectively. ResultsThe proliferation of xenografted tumor in Notch1 group was obviously inhibited compared with the untreated group. The weight of xenografted tumor in Notch1 group was significantly lower than that in the untreated group and empty vector group (0.574 ± 0.219 g vs. 2.642 ± 0.404 g and 2.606 ± 0.512 g, F= 26.642, P＜ 0.01). TUNEL assay demonstrated that the number of apoptotic cells per 500 cells in tumor tissue specimens was(87 ± 9) in Notch1 group, evidently higher than that in the untreated group(8 ± 2) and empty vector group(10 ± 3) (F = 194.266, P ＜ 0.05 ). Further, RT-PCR and Western blot revealed that the mRNA and protein expressions of Notch1 and bax were significantly upregulated, but those of bcl-2 were markedly downregulated in the Notch 1 group, with significant difference among the three groups(all P ＜ 0.05). ConclusionsNotch 1 gene can inhibit the growth of xenogra ffted human cutaneous squamous cell(SCL-1) carcinoma and induce SCL-1 cell apoptosis likely by upregulating bax expression and downregulating bcl-2 expression.

Objective To evaluate the clinical application of serum CYFRA21-1 detection during the diagnosis of lung cancer. Methods Serum level of CYFRA21-1 in 196 patients with lung cancer and 39 healthy controls were determined by the Elctro-chemiluminescence Immuno-assay ( ECLIA) , respectively. Results Serum level of CYFRA21 -1 ( range from 0. 30 μgg/L to 500.00 μg/L) in patients with lung cancer were significantly higher than those in the healthy control ( range from 0. 27 μg/L to 3. 29 μg/L,Z = -4. 65,P < 0.01). ROC analysis of diagnosis efficiency showed that the area under curve ( AUC) was 0. 735 (P < 0. 001 ). The confidence interval of 95% was from 0. 663 to 0. 807. Positive detection rate of CYFRA21-1 was 48. 8% (39/80) in squamous,31.7% (20/63) in adenocarcinoma and 22. 6% (12/53) in small cell lung cancer (SCLC) respectively, as well as total positive rate was 36. 2% (71/196). Stepwise regression analysis showed that serum level of CYFRA21-1 had a linear correlation with the squamous and the metastasis to liver or bone (r =0. 505 ,P <0. 05). Conclusions Serum level of CYFRA21-1 increases the diagnostic sensitivity, which is helpful for determining histological types, monitoring the metastasis of liver and bone, and evaluating the treatment response in patients with lung cancer.
