OBJECTIVETo observe preliminary efficacy of decompressive unilateral improved transforaminal lumbar interbody fusion (TLIF) for the treatment of lumbar degenerative diseases.

METHODSFrom August 2009 to December 2011, 28 patients with lumbar degenerative diseases were treated by decompressive unilateral improved TLIF,including 16 males and 12 females with an average of 61 (aged 46 to 71) years old,the courses of disease ranged from 6 months to 6 years. Among them, 20 cases suffered from lumbar spinal stenosis, 8 cases were lumbar disc herniation. Decompressive range included single segment in 24 cases,and double segments in 4 cases; 15 cases were performed operation on the left side, 13 cases on the right side. JOA lower back pain scoring system (29 points) were applied for evaluate preoperative and postoperative symptoms, physical signs and sphincteral functions;Visual analogue scale (VAS) were used to evaluate preoperative and postoperative low back pain.

RESULTSAll patients were followed up 6 to 28 (mean 14) months. Postoperative JOA score and VAS score were 17.9 +/- 2.2, 2.8 +/- 0.7 respectively,and preoperative JOA score and VAS score were 8.5 +/- 1.7, 8.6 +/- 1.2, respectively. There were significant meaning in JOA and VAS scores before and after operation (P < 0.05). Twenty-eight patients were all obtained intervertebral synostosis.

CONCLUSIONDecompressive unilateral improved TLIF for treatment of unilateral radicular lumbar spinal stenosis and lumbar disc herniation,which has advantages of minimally invasive,curative effects,decrease medical costs,is worthy spreading in clinical.

Objective To determine the effects of EGCG on lipopolysaccharide ( LPS)-induced neuroinflamma-tion and investigate the role of neuroprotection mediated by EGCG .Methods Primary cultures of rat gliacyte were used as an in vitro model to examine the effects of EGCG on LPS-induced neuronal damage .The intracellu-lar Glu andγ-GABA were quantified via HPLC .Then the protein level of TNF-α,IL-1βand IL-8 was determined by ELISA and Western blot assay .Results Compared with the control group , LPS apparently induced the pro-duction of intracellular ROS ( P<0.05 ) and released the TNF-α, IL-1βand IL-8 in the primary cultures super-natant (P<0.05).Compared with the LPS group,EGCG significantly attenuated the release of TNF-α, IL-1βand IL-8 ( P<0.05 ) and the level of iNOS protein ( P<0.05 ) .LPS apparently induced the production of intra-cellular ROS( P<0.05 ) and released the TNF-α, IL-1βand IL-8 in the primary cultures supernatant ( P <0.05 ) .EGCG significantly attenuated the release of TNF-α, IL-1βand IL-8 ( P<0.05 ) and the level of iNOS protein(P<0.05), and rugulated the concentration of Glu/γ-GABA(P<0.05).Conclusions EGCG is effective in protecting hosts against LPS-induced neuroinflammation through anti-inflammatory effects and regulating extracel-lular Amino acid levels .

OBJECTIVETo reconstruct a penis with sensation and erectile function maintained by corpora cavernosa lengthening and skin flap transferring in the penis defect cases.

METHODSThe procedure was based on the use of releasing the suspensory ligaments and part of crus, various flaps were designed as coverage material. Penis residual stump was advanced to anterior portion of the newly reconstruction penile body as "glans".

RESULTS40 patients with penis defect have been operated by the above methods. In the cases, length of the penis varied from 0.5-4.0 cm in the flaccid, 1.5-5.0 cm in erect state before operation. And after operation, it turned to 5.0-8.5 cm in the flaccid, 7.0-12.5 cm in erect state. Most of the patients recovered gross tactile sensation and had satisfactory erectile function.

CONCLUSIONWith this method, the reconstructed penis tends to have a better appearance and function. It's a more optimal method compared with the conventional operation.

Objective: To investigate the relation between ser um hyaluronic acid (HA) concentration and cryopreservation-reperfusion injury. Methods: The animals were randomly assigned to 3 groups: (1 ) group A: the control; (2) group B: liver allografts were stored in lactated R inger's solution (0℃) for 2 h before implantation; (3) group C:liver allografts were stored in lactated Ringer's solution (0℃) for 4 h before implantation. Th e serum sample and liver specimen were taken up at 2 h and 4 h after transplanta tion to detect the concentration of HA, AST and LDH, and to get pathologic obser vation. Results: Serum HA increased earlier and decreased more s hortly than AST and LDH after transplantation in group A. Serum HA increased sig nificantly in group B and C, much higher than that in group A(P<0.01). The i njury of vascular endothelium and the disorder of hepatic sinuses and hepatic lo b ules were observed in group B and C. In the specimen of 4 h in group C, evident infiltration of inflammatory cell was present. Conclusion: Cryopreservation leads to injury of endothelial cell and reperfusion aggravat es this injury. The serum HA concentration indicates the degree of cold ischemia -reperfusion injury.

OBJECTIVETo investigate of the value of monitoring of saturation of blood oxygen of the injured extremity on prevention of osteofascial compartmental syndrome.

METHODSTwenty patients of osteofascial compartmental syndrome included 13 male and 7 female with an average age of 32 years ranging from 13 to 60. There were 13 cases of tibial and fibual fractures, 3 cases of tibial plateau fractures, 4 cases of femoral shaft fractures. SpO2 on the end of injured extremities were dynamic monitored and osteofascial compartmental pressure was measured by modified Whiteside method. The data of two group were compared.

RESULTSAmong 20 cases, it's negative correlation between the data of pulse blood oxygen saturation and osteofascial compartmental pressure.

CONCLUSIONThe method of dynamic monitor extremity SpO2 can reflect indirectly the ischemia in muscle and nerve and report the early diagnosis and management of osteofascial compartmental syndrome.

Objective To study the exact function of human gene 5 transactivated by pre-S1 protein of hepatitis B virus(PS1TP5)by investigating the gene expression of PS1TP5 in yeast cells. Methods Reverse transcription-polymerase chain reaction(RT-PCR)was performed to amplify the gene of PS1TP5 using the mRNA of HepG2 cells as template and the gene was cloned into pGEM-T vector.The gene of PS1TP5 was cut from pGEM-T-PS1TP5 vector and cloned into yeast expressive plasmid pGBKT7,then pGBKT7-PS1TP5 was transformed into yeast cell AH109.The yeast protein was isolated and analyzed with sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE) and Western hybridization.Results PS1TP5 gene was successfully amplified and identified by DNA sequencing.The digested fragment was cloned into pGBKT7 vector and transformed into yeast cell AH109.The results of SDS-PAGE and Western assay showed that the relative molecular weight of the expressed product was about 36 950,and PS1TP5 protein existed in yeast cells.Conclusion The findings suggest that PS1TP5 can be successfully expressed in yeast cell.
