0.05) from that of the cryoprecipitate, but was shorter than that in the FFP and frozen platelet. Conclusion The clinical use of the platelet cryoprecipitate suspension is superior to that of common blood components, because it includes platelets and coagulable factors.
3.More are awaiting for craniofacial intervention
Journal of Interventional Radiology 2001;0(06):-
The scale of craniofacial intervention lies between the fields of neuro-intervention and peripheral intervention for the main purpose to investigate,diagnose and treat the disease entities originating from or supplied by the external carotid arterial system. Patients are usually refered to the oral and maxillofacial surgery,plastic surgery and otolaryngeal surgery. Craniofacial intervention includes mainly the diagnosis and treatment with adjuvant embolization of high-flow vascular diseases,intra-arterial chemotherapy of malignant tumors,embolization of epistaxis,etc. At present,there is no consensus with regard to the diagnosis and treatment of some craniofacial diseases,therefore further investigation and discussion are needed.(J Intervent Radiol,2006,15: 321-322)

Multidrug resistance (MDR) is widely thought to be a major cause of the failure in cancer chemotherapy. The detection of MDR marker is therefore valuabe in studying the mechanisms of MDR and to predict response to chemotherapy in patient with carcinoma. Previous studies have examined MDR marker in gastric cancer, but the major part of the investigation in patients have focused on a single parameter. The purposes of this study were to detect the expression of glutathione S transferase pi(GST ?), multidrug resistance associated protein(MRP), lung resistance protein(LRP) and multidrug resistance gen 1 (MDR1) in the patients with primary gastric cancer, who had not received prior chemotherapy, and evaluate the correlation between GST ?, MRP, LRP and MDR1. The expression of GST ?, MRP, LRP and MDR1 mRNA in carcinoma tissue and the adjacent non cancerous tissue from 50 patients was examined by semiquantitative reverse transcription polymerase chain reaction (RT PCR). The positive rate of GST ? mRNA, MRP mRNA, LRP mRNA and MDR1 mRNA in gastric cancer tissue were 36.00%, 12.00%, 10.00%, and 10.00% respectively. Their expression in gastric cancer tissue was significantly higher than that in the adjacent non cancerous tissue. The overall positive rate of their expression in gastric tissue was 48.00%. The results indicated that GST ? mRNA, MRP mRNA, LRP mRNA and MDR1 mRNA are overexpressed in various degrees and no co expression exists among the studied genes in gastric cancer,and perhaps intrinsic MDR exists in 46% patients with primary gastric cancer .

Objective To investigate the influence of Norcantharidin(NCTD)on apoptosis-related gene expression of gastric cancer cell line SGC-7901.Methods The experiment was divided into control group,5-Fu group,NCTD group and 5-Fu+NCTD group.The inhibitory rate,apoptosis rate and expression of survivin,bcl-2,and caspase-3 were detected by MTT assay,flow cytometry and SABC immunohistochemical method,respectively.Results NCTD showed that the inhibitory effect on growth of SGC-7901 cells with a dose-and time-effective dependent manner.The apoptotic rate increased from(8.30?1.49)% to(20.56? 1.32)%.The expressions of survivin decreased from(86.57?4.39)% to(26.11?2.27)% and bcl-2 from(85.35? 3.25)% to(30.26?1.83)%,while caspase-3 increased from(54.49?3.07)% to(92.78?2.47)%,5-Fu had the synergistic effects with NCTD.Conclusion NCTD can inhibit the growth of SGC-7901 cell lines.5-Fu had the synergistic effects with NCTD.The mechanism might correlate with induction of cell apoptosis via effect of the expression of apoptotic-related genes such as survivin,bcl-2 and caspase-3.

BACKGROUND: It has been reported that magnesium sulfate(Mg2SO4)treatment has a satisfactory effect on brain ischemia-reperfusion injury, but its effect on spinal cord ischemic injury remains unclear.OBJECTIVE: To evaluate the effects of intravenous administration of Mg2SO4 on spinal cord ischemia-reperfusion injury and further probe into its mechanism.DESIGN: Randomized controlled repeatedly measuring design based on the experimental animals.SETTING: Central research laboratory of a university hospital.MATERIALS: The experiment was conducted in the Central Research Laboratory, Medical College of Xi' an Jiaotong University from April 2003 to June 2004. Twenty-seven New Zealand white rabbits with body mass of 1.9to 2. 5 kg were included. The rabbits were randomly divided into Mg2SO4group, normal saline group and sham-operation group with 9 rabbits in each group.METHODS: The lower segment of the kidney under abdominal aorta was occluded for 30 minutes and 48-hour reperfusion was performed to establish ischemia-reperfusion model of lumbosacral segment of spinal cord. Mg2SO4group (Group A, n = 9) received Mg2SO4 at the dose of 0. 25 mL/kg per hour throughout this procedure; the same volume of saline solution was used in normal saline group(Group B, n=9) . Animals of sham-operation group (Group C, n = 9) were anesthetized and received laparotomy without aortic occlusion. The somatosensory evoked potential(SEP) was detected before ischemia, 30 minutes after ischemia, and 1, 2, 8, 16 and 24 hours after reperfusion. Motor function score was assessed in Mg2SO4 and saline groups 24 and 48 hours after reperfusion. After reperfusion for 48 hours, the animals were killed and histopathological test was performed on the spinal cord.MAIN OUTCOM MEASURES: Motor function score, SEP monitoring and spinal histopathological test.RESULTS: The latency of SEP(Nt) was markedly longer 30 minutes after ischemia in Mg2SO4 group. It was obviously recovered during the first two hours after reperfusion compared with during ischemia, but was obviously prolonged after that. Waveform disappeared 30 minutes after ischemia in normal saline group. SEP amplitudes and latencies in sham-operation group did not change remarkably during the procedures and all the animals recovered without neurological deficits. At each reperfusion time point, the recovery of SEP(N1) latency was better in Group A than that in Group B( P < 0.05). The average motor function score at 24 hours and 48 hours after reperfusion was significantly higher in Group A[ (3.7 ±0.5) and(3.4 ±0.7) points] than that in GroupB [(3.0±0.7) and (2.6±0.9) points](P <0.05). The normal nerve cell counting of spinal cord 48 hours after reperfusion in Mg2SO4 group(23. 4 ± 3. 4) was significantly higher than that in saline group (12.3 ±3.2)(P < 0.01).CONCLUSION: Intravenous Mg2SO4 administration may reduce spinal cord injury and preserve neurological function in transient spinal cord ischemia in rabbits.
