Journal of Interventional Radiology 1994;0(04):-
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.
2.Venous stenosis model induced by local mechanical injury with the presence of surgical arteriovenous fistula in swine
Journal of Interventional Radiology 1994;0(04):-
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 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.

Aim To analyze THANK gene expression in peripheral blood mononuclear cells(PBMC) stimulated with different stimulators and to clone whole length human THANK gene. Methods PBMC were conventionally isolated and cultured in RPMI1640 containing 10% FCS. After stimulated with LPS,TNF α ,IL 2,IFN γ ,PHA or PMA,the THANK gene expression in PBMCs was analyzed by RT PCR and THANK cDNA was cloned. Result RT PCR detection showed that THNAK gene expressed in PBMCs after stimulated with interferon γ for 3 days, whereas THANK'expression could not be detected after stimulated with LPS,TNF α ,IL 2,IFN γ ,PHA or PMA respectively. Then THANK gene was cloned by cloning PCR product and sequenced. Conclusion Human THANK gene is cloned successfully, thus providing the possibility for further research of THANK'function.

A CdTe/ZnSe quantum-dot submicrobead ( QBs ) , which exhibited fluorescence intensity approximately 2800-fold stronger than that of single quantum dots, was conjugated with the anti-histidine rich protein( HRP )-Ⅱ mAbs using N-( 3-( Dimethylamino ) propyl )-N'-ethylcarbodiimide hydrochloride ( EDC ) method as fluorescence probe. The goat anti-HRP-Ⅱ polyclonal antibodies and donkey anti-mouse polyclonal antibodies were sprayed onto the nitrocellulose membrane as test line and control line, respectively. The resultant fluorescence probes were introduced to the immunochromatographic strip for the quantitative determination of Plasmodium falciparum. For determination of Plasmodium falciparum in serum, the QBs based immunochromatographic strips exhibited a good dynamic linear range from 5 . 8 Parasite/μL to 8010 Parasite/μL with a limit of detection of 5. 8 Parasite/μL. The detection time of the proposed QBs based immunochromatographic strips for each sample was only 15 min. Moreover, the recovery rates of the intra-and inter-assay ranged from 93. 0% to 111. 9%, and 98. 3% to 115. 1% respectively, while the relative standard deviations ( RSDs) of intra-and inter-assay were below 5%.

Objective: To prepare highly purified THANK protein. Methods: THANK was efficiently expressed in E.coli as inclusion bodies. After bacteria were lysed under ultrasonication, TE buffer,1% TritonX and 2 mol /L urea was used to efficiently extract inclusion bodies. After denaturation with 8 mol/L urea,THANK was partially purified by Sephacryl S-200 chromatography, and then subsequent refolding step was optimized for a maximal recovery of biological active protein. The renatured THANK was purified to homogeneity with Q Sephadex Fast Flow gel filtration and then desalted by Sephadex G-25 chromatography. Results: The purity of biologically active THANK was above 97% in SDS-PAGE densitometric studies. Conclusion: An effective method of denaturation, renaturation and purification of recombinant THANK is established.
