Ketamine is mighty and short effective antalgic, advantaged in shock, asthma, etc. but it is restricted clinically because of serious side-effect. Today, low-dose ketamine(≤1 mg/kg) combined with opiates can enhance the efficacy of the opiates so that the dose of the opiates decrease relatively. The ketamine-opiates solution has enough stability and respiratory problems don't appear. So it is feasible that the combination of the two medicines can be used for patients with cervical spinal cord injury, who are susceptive to the respiratory distress and especially for the patients with depression.

Objective To study the growth inhibitory and apoptosis inducting effect of paclitaxel on human osteoblastic cell line U-2 OS. Methods U-2 OS cells were treated with various concentrations of paclitaxel. Proliferation was determined by cell count in a Neubauer cytometer chamber. Viability was assessed by trypanblau dye exclusion. Paclitaxel induced morphologic alterations were visualized, using light and transmission electron microscopy. The extent of paclitaxel induced apoptosis was determined by flow cytometry and immunohistochemical detection (TdT mediated dUTP nick end labeling technique, TUNEL). Results Paclitaxel had a growth inhibitory and apoptosis inducting effect on U-2 OS cell. The cell treated with paclitaxel initially show G2/M arrest; follow by apoptosis. A characteristic apoptosis change including nuclear disintegration and chromatin agglomerate were displayed. Lots of multinucleate cells appeared, which was not seen on the cell treated with other chemotherapeutic agents such as cisplatin and adriamycin. Also, extensive DNA cleavage was detected by immunohistochemical technique. Conclusion Paclitaxel has an obvious growth inhibitory and apoptosis inducting effect on osteosarcoma cell line by induce a G2/M arrest and inhibit the mitosis. The effect of paclitaxel displays a time dependent and dose dependent manner.

Objective To investigate a potential role for ORF50 promoter of human herpesvirus 8(HHV 8)in reactivation of HHV 8 in primary effusion lymphoma(PEL)BC 3 cells by HIV 1 related inflammatory cytokine,hepatocyte growth factor/scatter factor(HGF/SF). Methods The persistent stimulation of BC 3 was performed by recombinant HGF/SF and treated BC 3 cells were collected at the 3 rd and 7 th day after persistent stimulation respectively. Northern blot, quantitative PCR(real time PCR), and electron microscopy(EM)were carried out to detect the expression of mRNA of minor capsid protein ORF26 and the presence of viral particles of HHV 8 from treated BC 3 cells. Co transfection of BC 3 and human umbilical veil endothelial cells (HUVECs) with HHV 8 ORF50 promoter driven luciferase construct built previously by us and recombinant expression plasmid named pEV containing HIV 1 Tat coding gene was performed and stimulation of co transfected cells with recombinant HGF/SF and/or HIV 1 recombinant gp120 was conducted at 24 hours after transfection to induce luciferase gene expression. Then relative luciferase activity unit(RLU) was calculated at 24 hours after stimulation. In the meantime, stimulation of co transfected cells with 12 O tetradecanoylphorbol 13 acetate(TPA) was performed to be used as positive control. Results It was found that HGF/SF induced an 4.1 folds increase in mRNA expression of ORF26 when it was added individually to BC 3 cells at the 7 th day after persistent stimulation. Viral particles of HHV 8 were readily identified in BC 3 cells stimulated with HGF/SF at the 7 th day with EM analysis. Recombinant HGF/SF could upregulate promoter activity of HHV 8 ORF50 promoter in BC 3 and HUVECs cells and however, HIV 1 Tat and gp120 failed to act synergistically with HGF/SF to enhance ORF50 promoter activity in HUVECs. Conclusions The results show that HIV 1 related inflammatory cytokine HGF/SF is responsible for the induction of HHV 8 lytic cycle replication and the induction may be, at least partly mediated by ORF50 promoter of HHV 8.

Objective To observe the level of homocysteine(Hcy),high sensitive C-reactive protein(hs-CRP)and D-Dimer(D-D) in peripheral blood of patients with coronary heart disease,and to explore their values in clinical diagnosis of the coronary heart dis-ease(CHD).Methods Total of 95 patients with coronary heart disease were selected including 27 patients with AMI,42 patients with UAP and 26 patients with SAP.50 health examination volunteers were served as contro1.The levels of Hcy,hs-CRP and D-D were measured.Results The levels of Hcy in AMI group,UAP group and SAP group were significantly higher than those in con-trol group(P <0.05).The levels of hs-CRP and D-D in AMI group and UAP group were significant higher than control group and SAP group(P <0.05).The level of hs-CRP in SAP group was much higher than the control group(P <0.05),whereas the level of D-D in SAP group was not significantly different from control group(P <0.05).Conclusion The changes of serum levels of Hcy, hs-CRP and D-D are related with the occurrence and development of CHD.The joint detection of Hcy,hs-CRP and D-D can better reflect the severe degree of CHD,and could be helpful for early diagnosis,therapy and prognosis of CHD.

Objective To evaluate graft isometry after anatomic single bundle reconstruction of anterior cruciate ligament (ACL) using dynamic computed tomography (CT).Methods A retrospective study was conducted of the 14 patients who had undergone single bundle ACL reconstruction from June to August 2015.They were all men,with an average age of 28.6 years (range,from 18 to 39 years).At 6 months after operation,they received dynamic CT scanning during a cycle of knee extension to flexion.3D bone models representing the knee at different flexion positions (0°,30°,60°,90°,and 120°) in each patient were reconstructed from the CT images.The grid method was used to locate the positions of the central footprints of the tibial and femoral tunnels.The lengths between the entries of the femoral and tibial tunnels were measured from each tunnel entry to reflect the graft length change.Furthermore,we measured the isometry at the over-the-top position of the femur and at the anatomic tibial position.Results All the tunnel entries were located at the central area of the ACL anatomic attachment.The reconstructed ACL was the longest when the knee was in full extension.The length was gradually shortened between the femoral and tibial tunnels during flexion of the knee from 0° to 90°.The anatomic position showed an average of 4.82 mm shortening and the over-the-top position an average of 3.28 mm shortening.The length excursion increased in early flexion from 0° to 30° (2.91 ±0.91 mm on average) and reduced in later flexion from 90° to 120° (2.98 ± 1.41 mm on average).Conclusions None of the reconstructed ACL was isometric.A graft length may be the longest when the knee is in full extension and decrease gradually during the flexion from 0° to 90° and increase gradually during the flexion of 90° to 120°.The graft should be fixed when the knee is in the flexion of 30°.

Objective To investigate the change of the content of suppressor of cytokine signaling (SOCS-1) in the liver of septic mice and its working mechanism.Methods Adopted Cecalligation and puncture (CLP) to create models of sepsis and divided randomly adult male BALB/c mice into 8 groups,including normal controlled group,sham-operated group,and the killed groups 2 hours,6 hours,12 hours,24 hours and 48 hours after operation.After extracting the RNA and protein from the liver tissue of the mouse groups,reverse transcription polymerase chain reaction (RT-PCR) was adopted to determine the relative content of SOCS-1 mRNA in the tissue,Western blot was adopted to determine the relative content of protein and the SPSS statistics software was adopted to calculate the correlation.Then observed the pathological change of liver tissues,and detected SOCS-1 protein expression by immunohistochemistry.Results After CLP suergery,the expression of SOCS-1 on gene degree in the liver and the expression of SOCS1 on protein degree in the liver increased rapidly at the 6th hour ( P ＜ 0.05 ),with the former reaching peak ( P ＜ 0.05 ) at the 24th hour and the latter remaining high all the time.There were pathological changes such as fatty degeneration and necrosis in the septic liver tissue,hepatic SOCS-1 protein expression could be detected by immunohistochemistry.Conclusions CLP induced sepsis could lead to the increase of the expression of SOCS1 in the liver.

BACKGROUND: A new composite scaffold for cartilage tissue engineer ing has been employed to culture chondrocytes and overcome many limits related to traditional scaffolds, such as poor biocompatibility, inferior mechanical property, inappropriate biodegradability, and simplex structure which can not match layered structure of articular cartilage, etc. The new composite scaffolds provided a new approach for the research of cartilage tissue engineering.OBJECTIVE: To evaluate the feasibility and value of layered cylindrical collagen/hydroxyapatite (HA) composite for cartilage tissue engineering by observing how it absorbs chondrocytes and affects its cellular characteristics.DESIGN: Completely randomized design and controlled experimental study.SETTING: Department of Orthopaedics, Third Hospital Affiliated to Sun Yat-sen University, and College of Material Science, South China University of Technology.MATERIALS: The experiment was conducted at the central experimental laboratory of the Third Hospital Affiliated to Sun Yat-sen University from June to November 2004. One two-week-old male healthy New Zealand rabbit,which was bred in 20 ℃ and 40% humidity, was used in this experiment.METHODS: ①Right amount of deionized water was added into HA, collagen I solution was added to disperse HA, then carbodiimide was added in the mixture at a proportion for getting the collagen/HA composite at different ratios. Pour to the certain mould in successive layers. The upper layer was pure collagen and the bottom was pure HA. The prepared layered cylindrical collagen/HA composite was put into the ultra low temperature freezer, lyophilized, and sterilized by ethylene oxide for the following procedures. ② Chondrocytes of juvenal rabbit were isolated and multiplied in vitro, then chondrocytes were seeded onto porous collagen/HA composite scaffold and cultured. The effects of composite scaffold on chondrocytes'morphological changes, proliferation, and function were evaluated through a series of examinations such as inverted phase-contrast microscopy, histological, scanning electron microscopy and immunohistochemistry.MAIN OUTCOME MEASURES: ①Morphology of collagen/HA porousscaffold. ②The characteristics of chondrocytes cultured in vitro. ③ The chondrocytes' compatibility with the collagen/HA porous scaffold.RESULTS: ①Morphology of collagen/HA porous scaffold: Collagen/ HA was a cylindrical three-dimensional porous scaffold in layer structure with certain mechanical strength. The top layer was pure collagen, the bottom was pure HA, and the intermediate layer was collagen and HA composite.Under scanning electron microscope, the scaffold had irregular blowhole structure, the apertures were even and pores were communicated each other. The average pore diameter was about 147 μm. ②The characteristics of chondrocytes cultured in vitro: The chodrocytes that had just been isolated were spherical; rate of living cells was 95%. 24 hours later, the cells were going to attach to the wall, extend to be triangle or polygon. The cytoplasms were abundant with secretary granules inside. The cells kept on growing in monolayer and the multiply rate accelerated after passage, and chondrocytes overspreaded the culture flask in 4 days. After passaged for several times, the multiply rate decreased. In passage Ⅵ, the ability of cell division was decreased obviously, the cytomorphosis was clear. Cellular sizes were larger. Most of cells were shuttle-shape, less refracted with blur edges, which trended to age and dedifferentiate to fibroblast. ③The chondrocytes' compatibility with the collagen/HA porous scaffold: Cylindrical collagen/ HA composite scaffold in layer structure had good hydrophilicity. The chondrocytes adhered to the surface of the scaffold, proliferated and migrated toward the scaffold through the pore. Chondrocytes attached to wall of microholes of the scaffold had largely maintained a rounded morphology and could secrete the extracellular matrix on the porous scaffold.CONCLUSION: Cylindrical collagen/ HA composite scaffold in layer structure has good cellular compatibility.It is stronger in mechanical property than pure collagen, is anideal scaffold for cartilage tissue engineering.
