ADAM9, a member of ADAM family, plays an important role in development of many human diseases especially neoplasms as its metaUoproteinases activity and the ability of combining with integrins. This might help us find new therapeutic targetpoints and therefore offer new therapeutic approaches.

Objective To evaluate the diagnostic value of myocardial enzymes on the cardiac muscle injury for the children with acute mycoplasma pneumonia(MP).Method The levels of phosphocreatine kinase-MB(CK-MB),lactate dehydrogenase(LDH),aspartate aminotransferase(AST)in 48children with MP(MP group)were measured,48 normal children served as control group.Results The levels of AST,LDH,CK-MB were(37.18±6.15),(294.10±46.20),(84.50±13.70)U/L in acute stage in MP group,they were higher than those in control group[(25.14±10.50),(140.50±76.21),(19.50±4.10)U/L](P＜0.01).All the values above was descended in recovery phase in MP group,but the values of CK-MB[(27.80±8.40)U/L]and LDH[(189.50±69.73)U/L]were still higher than those in control group(P＜0.01 or＜0.05).Conclusions Children with MP may combine myocardial injuries and CK-MB isa parameter to diagnose the damage.Protection therapy for cardiac muscle should be performed on the children with MP.

B7H1 is a recently described B7 family member.Ligation of PD-1 receptors with B7hl on the surface of activated T cell inhibits T cell proliferation and cytokine production. B7H1 plays a negative regulatory role in peripheral tolerance, autoimmune diseases and chronic infections.B7H1 also has been found to be largely expressed on a broad range of cancers and is thought to contribute to immune evasion by cancers. Blockade of B7H1/PD-1 pathway may contribute to the treatment of autoimmune diseases and maligant tumors.

Objectives To evaluate the application of systemic octreotide radioactive imaging in diagnosis and follow-up for children with neruoblastoma (NB). Methods Clinical data of 14 children with NB applied systemic octreotide radioac-tive imaging from April 2006 to March 2011 were collected and analyzed. For the ifrst-visit patients, they were applied with systemic octreotide radioactive imaging at the ifrst follow-up appointment after routine treatment. And for recurrent or sus-pected recurrent cases, systemic octreotide radioactive imaging was applied before the treatment and after 2-3 weeks chemo-therapy. Results Nine of 14 patients were male and 5 were female with a median age of 4.8 years (1-10 years). According to In-ternational Neuroblastoma Staging System (INSS), 4 cases were categorized as stage 3 and 10 cases were categorized as stage 4. The uptake rate of systemic octreotide radioactive imaging in primary site or metastasis sites of 8 cases were higher than nor-mal site with positive rate of 57.14%(8/14). One case was conifrmed as false positive by treatment and imaging examination. Six cases were negative in primary site or metastasis sites with negative rate of 42.86%(6/14). One case was conifrmed as false negative via treatment and imaging examination. Therefore, the sensitivity of systemic octreotide radioactive imaging reached 85.71%(12/14). Conclusion Systemic octreotide radioactive imaging could be one of the effective methods for NB in diagno-sis, follow-up and evaluation of prognosis.

AIM To investigate the mechanism of anti-tumor effects of curcumin on human SPC-A1 cells. METHODS Cell culture、fluorescence microscope、TUNEL method and irradiation immunity techniques were used. RESULTS ①By the action of curcumin, SPC-A1 cells grew against the wall and then peeled off gradually;fluorescence microscope showed the nucleus broke into pieces, and cell split into apoptosis bodies in different sizes; The TUNEL method further certified that apoptotic cells reached 42 67% at the concentration of 20 ?mol?L -1 curcumin at 24 h. ②The level of intracellular cAMP concentration in the SPC-A1 cells,treated with curcumin, was significantly higher than that of the control group. ③Treated with 20 ?mol?L -1 curcumin for 24 h, the expression of Caspase-8 mRNA of human SPC-A1 cells was up-regulated. CONCLUSION Curcumin can induce the apoptosis of SPC-A1 cells, and one of its molecular mechanism may be associated with the rising of the level of intracellular cAMP concentration, and up-regulating expression of Caspase-8.

0.05). However,the accuracy in placement pedicle screws and derotation rate of apical vertebrae were much higher in the individually treated group than those in the standard group (P=0.001,0.02).[Conclusion]The accuracy in placement pedicle screws and correction effects on transverse plane of patients with Lenke Ⅰ AIS can be improved significantly by individual selection of entrance point.

Objective:To review the application of antihypertensive drugs in Wuhan Xiehe Hospital in the period of 1996 to 1998.Methods:Statistically analyze the application of antihypertensive drugs during the period in terms of their types,sales income,DDDs*d-1 as well as the changes of daily expense on drugs.Results:During the period analyzed,the newly applied drugs are mainly ACEI drugs.The DDDs*d-1 of metoprotol,benazepril,nifedipine and nimodipine had been among the highest.The increase of DDDs*d-1 was rapid.The newly prescribed drugs were mainly oral and retard preparations.Conclusion:The Prescription of antihypertensive drugs in Wuhan Xiehe Hospital was rational and in accordance to the principles of convenience and cost-effectiveness.

20?10 9/L) were 12 (8-20), 17(10-28) and 21 days (7-78), respectively. The average follow-up period was 7 3 years(ranged from 1 month to 14 years). The overall survival (OS) and death rates after transplantation were 70%(18/26) and 30%(8/26) respectively. Transplant-related mortality was 7 7%(2/26). Conclusion The combination of chemotherapy and G-CSF is an effective and low toxicity protocol for the mobilization of peripheral blood stem cells. APBSCT can be safely performed in children with malignant tumors.

Objective To analyze the causes, prevention and treatment measures for nerve palsy complications in artificial hip replacement. Methods A total of 413 consecutive hip replacements performed from January 1991 to December 2001 were retrospectively studied. There were three cases of nerve palsy with a prevalence of 0.73%. Among them, there were two cases of sciatic nerve palsy and one femoral nerve palsy. Results The causes for nerve palsy in these three cases were hypotension shock due to excessive anticoagulation against deep venous thrombosis, hematoma compression and unknown causes respectively. The neuronal function of three cases of nerve palsy was recovered at different degrees through correction of shock, clearance of hematoma and rehabilitation therapy. Conclusions The causes for nerve palsy complication during artificial hip replacement are direct or indirect traction, compression and ischemia. Understanding the etiology of nerve palsy to avoid the nerve injury, immediate and correct management play an important role in prevention and treatment of nerve palsy during artificial hip replacement.

Central image server and ultrasound information system server we re connected together with all workstations by computer Ethernet network, thus, using switch, and connecting to hospital internet WWW server to distribut the image and report. Results Ultrasound DICOM digital images and high quality video image successfully acquired, displayed, processed and network communicated, seamless integrated with hospital information system, functions such as image central storage, computer-aided report and sharing printing were implemented. Conclusions Application of ultrasound image management system improves the administration and increases work efficiency in imaging diagnosis, promotes the reform of working pattern of doctors and provides more convenience for work, research and study.
