Objective: To investigate the inhibitory effect of survivin antisense oligonucleotide (ASODN) on the expression of survivin gene and proliferation of human hepatocellular carcinoma cell line SMMC-7721. Methods: The 20 mer antisense oligonucleotide (ASODN) targeted to the promoter region of survivin mRNA was designed and synthesized. The expression of survivin gene in hepatocellular carcinoma cell line SMMC-7721 was blocked by means of ASODN transfection mediated by DOTAP liposomal reagent. The changes of survivin protein and mRNA expression after transfection were as-sessd by Western blot and in situ hybridization, respectively. The apoptotic rate was detected by flow cytometer. The changes of cell adherent rate, cell growth activity, and the inhibitory rate of cell growth were also studied. Results: The expression of survivin protein and mRNA were decreased markedly after survivin ASODN transfection. Meanwhile, the cell adherent rate also decreased markedly while the apoptotic rate increased markedly. Conclusions: Transfection of ASODN targeted to the promotor region of survivin mRNA by DOTAP liposomal transfection reagent could down-regulated the expression of survivin protein and mRNA significantly in 7721 cell line and inhibit the proliferation of cancer cells. Survivin could be an important target in the therapy of hepatocellular carcinoma.

OBJECTIVE: To observe effects of three-dimensional EH composite template on repairing cranial bone defect. METHODS: A total of 53 inpatients were analyzed retrospectively at the Department of Neurosurgery, Taixing People's Hospital from July 2004 to May 2007, comprising 31 males and 22 females, aged 19-68 years. They were in accordance with cranial repairing indication. Reasons for skull defect: traumatic brain injury (41 cases), hypertension (7 cases), intracranial cancer (3 cases), intracranial aneurysm (2 cases). Thirteen patients developed bilateral cranial defect. The defect region: frontal (5 slices, comprising 2 with severe orbital part defect), temporal (9 slices), frontotemporal (42 slices), temporoparietal (3 slices), parietoocipital (4 slices),frontoparietal (3 slices). The smallest single-chip defect size was 4 cm × 6 cm, and the largest one was 12 cm×18 cm. All the patients were mended by three-dimensional EH composite template using spiral CT (≤5 mm thickness) scanning, CAD three dimensional reconstruction, quickly modeling technique. Infection of incisional wound, rejection and complications were observed. RESULTS: A total of 53 patients were followed up, with an average follow-up period of 18 months, and all of them were satisfied with the shapes (100%). Mild collection of the fluid under the scalp was found in 2 cases 4 days and 1 week following surgery, and disappeared after suction and pressure dressing. No other frequent complications were observed after cranioplasty. CONCLUSION: Three-dimensional EH composite template is an ideal material for cranial bone defect, because of its good biocompatibility, easy operation, good postoperative shape and less complications.

Objective To explore the therapeutic effects of peroxisome proliferator activating receptor γagonist-rosiglitazone on HMGB1 expression in liver tissue of rats with SAP. Method A hundred and twenty Wistar rats were randomly (random number) divided into the sham operation group(SO group, n = 20) ,SAP group ( n=80) and ROSI treatment group (n =20). SAP group were randomly further divided into the 3 h, 6h, 12 h and 24h subgroups with 20 rats in each group. SAP model was made by retrograde injection of 5 % sodium deoxycholate into the biliopancreatic duct. The serum amylase, AST and ALT, and pathological scores of pancreas and liver tissue were observed. The expression of NF-κB mRNA and the level of HMGB1 protein were investigated respectively by Reverse transcription polymerase chain reaction (RT-PCR) and Westem blot method, respectively. SPSS 16.0software was used to make one-way ANOVA, q -test and correlation analysis. Results Serum amylase, AST and ALT, and pathological scores of pancreas and liver tissue, and the level of HMGB1 protein were markedly increased in each subgroup of SAP compared with SO group ( P ＜ 0.01). The level of HMGB1 protein was positively correlated with the changes of AST, ALT and pathological scores of pancreas and liver tissue. Correlation was not found between HMGB1 and amylase. Treatment with ROSI could significantly reduce the expression of NF-κB mR-NA and the levels of HMGB1 protein, serum AMY, AST and ALT, and pathological scores of pancreas and liver tissue in comparison with 24 h subgroup of SAP (P ＜0.01). Conclusions As a late-acting mediator of inflammation, HMGB1 was involved in the pathophysiological process of SAP-related liver injury. ROSI can reduce the liver injury by inhibition of the expression of the HMGB1.

Aim To investigate and compare the phar-macokinetics of doxapram injection in healthy subjects of different Chinese nationalities including Han, Mon-golian, Korean, Hui and Uigur, and the influence of gender,in order to provide instruction and help for the usage of doxapram for both clinic and remedy of battle wound. Methods An HPLC-UV method was used to determine the plasma concentration of doxapram. Fifty healthy subjects ( five males and five females of each nationality) were recruited for the study. A single dose of 50 mg doxapram was administered intravenously to the healthy subjects, and blood samples were collected at various predetermined time points. The pharmacoki-netic parameters were calculated by DAS software and were compared by SPSS 13. 0 software, in order to as-sess the influence of nationality or gender on pharmaco-kinetics of doxapram. Results The results indicated that the pharmacokinetic profile of doxapram in vivo could be described as two-compartment model. The main pharmacokinetic parameters for Han, Mongolian, Korean, Hui and Uygur were as follows: Cl ( 0. 25 ± 0. 11 ) , ( 0. 33 ± 0. 11 ) , ( 0. 27 ± 0. 07 ) , ( 0. 26 ± 0. 06) and (0. 39 ± 0. 25) L·h-1 ·kg-1 , while Cmax (1. 55 ± 0. 52 ) , ( 1. 02 ± 0. 30 ) , ( 1. 31 ± 0. 47 ) , (1. 48 ± 0. 46 ) and ( 0. 99 ± 0. 35 ) mg · L-1 . The AUC0-12. 5 , AUC0-∞ and Cmax of Chinese Han were sig-nificantly higher than those of Uigur and Mongolian ( P<0. 05 ) , while there was no significant difference in other parameters ( P>0. 05 ) . There were statistically significant differences in Vc , Vd and CL between young males and females ( P < 0. 05 ) . Conclusion The large inter-individual variation in the main pharmacoki-netics suggests the dosage of doxapram should be ad-justed for different nationalities for both clinic and rem-edy of battle wound.

Objective To investigate the clinical significance of flow cytometry (FCM) assay in following up of the minimal residual disease (MRD) used for predicting relapse and guiding chemotherapy. Methods The clinical data of 43 acute leukemia patients diagnosed by MIC were collected in our hospital from 2005 July to 2008 June.Bone marrow aspirates were collected from 43 patients with newly diagnosed acute leukemia after induction therapy and during constimulation therapy. The cells with leukemia associated with immunophenotype were investigated using FCM, as immunologic target of MRD. Results MRD were detected earlier in predicting the relapse than those of the traditional bone marrow cells morphology assay by an average of 4-6 months. The results of the MRD following up: MRD was negative at CR in 26 cases, 6 cases relapse, 20 cases of them were kept negative during following up. MRD was positive in 17 cases at CR, 9 cases of them were relapse. 4 cases after intensified chemotherapy the MRD became negative and kept egative for more than one year. The MRD of the 43 cases at CR were divided into 3 groups, MRD less than 1×10-4 group (A group) MRD between 5×10-3 and 1×10-4 group (B group) and MRD above 5×10-3 group(C group). By chi square test. There was no statistical significance between A group and B group, but there was tatistical significance between B group and C group (P=0.02). Conclusion The application of FCM in detecting MRD has important clinical significance in predicting relapse and guiding chemotherapy.

AIM: To evaluate the safety and efficacy of intravitreal bevacizumab ( avastin ) injection in patients with exudative age related macular degeneration ( AMD) .
METHODS: The records of patients treated with intravitreal injection of 1. 75mg bevacizumab for AMD were retrospectively reviewed. All patients were evaluated by complete ophthalmic examination, optical coherence tomography and fundus fluorescein and/or indocyanine green angiography. Observation was made on the best corrected visual acuity ( BCVA) , intraocular pressure, and the changes of lens, vitreous, central retinal thickness (CFT) and total macular volume (TMV), at 1d, 3d, 7d, 1mo and 6mo after the treatment and then compared with those of pre - operation. Repeated treatment with intravitreous bevacizumab occurred if there were signs of persistent or recurrent exudation. And all cases were followed up at least 6mo. An intravitreal injection of bevacizumab (1. 75mg) was given once every 6wk.
RESULTS:All 50 eyes of 48 patients with the average of 58±20. 46 years old were included. The mean baseline of BCVA and CFT were 0. 82±0. 53, and 364. 97±151. 83μm respectively. Although there was no significant decrease in mean CFT and TMV one week after the injection, the mean BCVA had significant improvement. At the last visit of 9. 7mo follow - up, BCVA, CRT and TMV showed significant improvements over baseline values. BCVA was improved by at least two lines in 32 eyes (64%),remained stabilization in 18 eyes (36%) at the last visit. A total of 98 injections were performed and the average number of injections was 1. 98 for each eye in the group. About 50%of re - injections gained at least two lines of vision improvement one week postoperatively. There were no serious adverse events during the treatment.
CONCLUSION: Intravitreal bevacizumab ( avastin ) injection for managing CNV due to age-related macular degeneration is safe and few side effects. Intravitreal avastin associated with improvement in visual acuity ( VA ) , which can reduce macular edema and choroidal neovascularization leakage. But a prolonged treatment effect needs further observation.

To evaluate the safety and efficacy of intravitreal bevacizumab injection in patients with macular edema (ME) induced by retinal vein occlusion (RVO).
● METHODS: The records of patients treated with intravitreal injection of 1. 75mg bevacizumab for ME induced by RVO were retrospectively reviewed. All patients were evaluated by complete ophthalmic examination, optical coherence tomography ( OCT) and fundus fluorescein angiography ( FFA ), etc. Best corrected visual acuity (BCVA), intraocular pressure, the change of lens and vitreous, central foveal thickness (CFT) were observed at 1, 2, 3, 6mo after treatment and compared with before treatment. Repeated treatment with intravitreous bevacizumab occurred if there were signs of persistent or recurrent exudation. All the cases were followed up at least 6mo. An intravitreal injection of bevacizumab (1. 75mg) was given at 6wk intervals.
●RESULTS: Fifty patients (56 eyes) with the average of (57±18. 56) years old were included. The mean baseline of BCVA, CFT were (logMAR0. 82±0. 63), (626. 5±178. 0)μm respectively. Although there was no significant decrease in mean CFT at 1wk after injection, the mean BCVA had significant improvement. Followed up at mean 10. 26 ± 5. 87mo, BCVA, CFT showed significant improvements over baseline values. The statistics of CFT at 1, 2, 3mo after injection were significant differences compared with before injection in each of the three groups. CFT at 1, 3, 12mo after injection were (365. 11±23. 212) μ m, (333. 42± 35. 526) μ m, (267. 6 ± 116. 8) μ m, which had a significant difference ( P < 0. 001), namely macular retinal thickness was thinner obviously that before treatment, ME was improved obviously. CFT was no significant difference at each time point after injection in the group of BRVO-ME and CRVO- ME (P> 0. 05). OCT image showed that after injection macular retinal thickness was becoming thinner. FFA showed that after injection macular fluorescein leakage decreased. BCVA was improved by at least two lines in 48 eyes (86%),remained stable in 8 eyes (14%) at the last visit. A total of 112 injections were performed and the average number of injections was 1. 96 in the group. About 50% of reinjections gained at least two lines of vision improvement at 1wk following the retreatment. There was no serious complications during the treatment.
●CONCLUSlON: lntravitreal injection of bevacizumab can improve visual acuity (VA) of RVO (CRVO and BRVO) in patients with ME, relieve ME, reduce the leakage of CNV, and repeated treatment is better. But a prolonged treatment effect needs further observation. There are no serious ocular and systemic complications occurred in our study.
