[Objective]To study the effect of improved universal pedicle screw systems which combined locking pedicle screws with sliding pedicle screws to correct the spinal deformities in growth period through posterior incision.[Method]From June 2000 to June 2006,209 spinal deformities in growth period were treated(106 males and 103 females),including 92 idiopathic scoliosis,72 congenital scoliosis,26 Scheuermanns diseases and 19 other kinds of spinal deformities.The age of patients ranged from 8 to 16 years(average 13.22 years).Locking pedicle screws were placed into pedicles of apical vertebra and the 3 to 5 adjacent vertebrae.Sliding pedicle screws were putted into pedicles of cephalic and caudal vertebrae.Double cross-links and rods were fixed and locked tightly.Sliding cross-links themselves could cannula prolonged to fit for the transverse development of vertebrae.[Result]Totally 209 cases with preoperative Cobbs angle 45 degree to 110 degree(average 68 degree)were instrumented with improved USS systems and 96 cases were followed up for 26～60 month.The length of spines were prolonged 4 cm to 15 cm with average 7 cm.With 26 months to 60 months follow-up,the whole spine growth was 230.4 cm with average 2.4 cm respectively.Rods broken were found in 6 patients and no other cmplication was detected.[Conclusion]Improved USS system which combined locking pedicle screws with sliding pedicle screws had the three dimensional power and intensity of traditional 3D instrumentations.Sliding pedicle screws and cross-links permitted longitudinal growth of the vertebrae and transverse development pedicles.

Hepatolenticular degeneration,namely Wilson's disease,an autosomal recessive disorder of copper metabolism.The author of this article gave a definition to toxin-pathogen,discussed the basic concept of collaterals disease briefly.And pointed out that hepatolenticular degeneration is a disease due to toxin-pathogen invading collaterals,which was caused by disorder of copper metabolism.This can result in toxin stagnating in collaterals and stagnation of blood stasis in collaterals in the initial stage,and collaterals injured at last.To improve QI-blood circulation and regulate the function of zang fu is important in order to accelerate elimination of toxin and prevent copper from stagnating. Specific therapy vary according to different clinical symptoms,such as promoting blood circulation for removing obstruction in collaterals and clearing toxin, clearing heat-fire and clearing toxin and dispersing stagnated liver-qi for promoting bile flow et al.

Objective To improve the diagnosis and treatment of eosinophilic lung disease.Methods Patients who were diagnosed with eosinophilic lung disease and hospitalized in the First Affiliated Hospital of Guangxi Medical University Hospital were retrospectively analyzed from January 2004 to August 2012.Data of etiology,clinical manifestation,imaging and pathological features,diagnosis and treatment were recorded.Results A total of 25 patients were diagnosed with eosinophilic lung disease including 9 chronic eosinophilic pneumonia,6 churg-strauss syndrome,and 10 cases of parasitic infection of which two patients were the simple pulmonary eosinophilia (L(o)ffler syndrome).Eosinophil counts in peripheral blood and bronchoalveolar lavage fluid (BALF) were increased.Arterial gas analysis showed varying degree of hypoxemia,which pulmonary function tests showed restrictive,obstructive,mixed ventilatory dysfunction.Chest CT showed bilateral flaky,streak or flake diffuse ground-glass infiltrates and reticular opacities.Results of pulmonary biopsy or skin biopsy identified diffuse eosinophil infiltration.Corticoidsteroid therapy alone or combined with immunosuppressive agents were both effective.Conclusion (1) Liver fluke and other food-borne parasites are the most common causes in eosinophilic lung disease; followed by unexplained chronic acidophilic granulocyte pneumonia; (2) In addition to histopathological evidence,the diagnosis of eosinophilic lung disease was made comprehensively based on clinical features,laboratory test,the BALF analysis,and imaging data.

Objective: To clone Fd and light chain genes of monoclonal antibody HAb18 against human hepatoma and verify their accuracy and liability. Methods: Total RNA was extracted from hybridoma cell line secreting MAb HAb18, and Fd and light chain genes were amplified by RT-PCR. After PCR products were ligated into pMD18T vector, positive clones were screened and DNA sequences were tested and analysed by relative softwares. Then, light chain and Fd genes were sequential cloned into phage display vector pComb3. After recombinant vector was transformed into E.coli XL1-blue, recombinant vector was rescued by helper phage M13K07 and the specificity of phages to antigen was detected by indirect ELISA. Results: The size of amplified Fd and light chain genes was separately 665 bp and 668 bp. The results of sequence analysis showed that both VL and VH contained 2 characteristic cystines and CH1 was IgG1 classes and CL was ?. ELISA result identified that expressed Fab antibody could specially bind to corresponding antigen. Conclusion: Fd and light chain genes of MAb HAb18 were successfully cloned, which lay a good foundation for constructing a diversity of engineering antibody.

Objective: To select anti-HAb18G (hepatoma associated antigen) human Fd fragments with guided selection of L chain of chimeric Fab-HAb18. Methods: The human Fd repertories genes were amplified by RT-PCR from PBMC of hepatoma patients, and cloned into the vector pComb3X with chimeric L chain to construct the human-mouse hybrid Fab phage library. HAblSGE, extracellular region of HAblSG, was used as antigen to screen. The positive clones was obtained by ELISA and FCM with p Ⅲ-fusion Fab antibody. The DNA sequences were analyzed. Results: A human-mouse Fab antibody library were constructed with 2?107 PFU. After 6 rounds panning, 7 positive clones were obtained with ELISA and FCM. And sequences of 2 clones with better affinity were same. The CHI belonged to the IgG2 class as the parent Fd, and the variable region belonged to VH3 family. Conclusions: Through the construction of the HuMFab phage antibody library and chemeric L chain-guided selection, we get the available human Fd fragments for subsequent research.

Asialogycoprotein receptor (ASGPR) is a specific receptor of mammalian hepatocytes,exclusively up-take the glycoprotein in the blood.The number of ASGPR correlates significantly with liver function,and the reduction of the number of ASGPR suggest liver dysfunction.Decreased ASGPR in patients with liver cirrhosis or portal hypertension or hepatocellar carcinoma,lead to varying degrees of liver dysfunction,which made it more susceptible to post operative complications.liver ASGPR scintigraphy with Technetium-99 m DTPA-galactosyl human serum albumin (99m Tc-GSA),combinating with single photon emission computed tomography (SPECT) technology can assess the functional reserve of remnant liver and predict incidence of postoperative complications,then assist to evaluate the use fulness for clinically surgical decisions.Current situation and progress of 99mTc-GSA SPECT imaging in hepatic surgery were reviewed in the paper.

Objective To investigate the relation between serum asymmetric dimethylarginine (ADMA) level and endothelial function before and after living donor kidney transplantation in uremic patients.Methods A total of 38 renal transplant patients (21males and 17 females) and 36 healthy controls (20 males and 16 females) were enrolled. Plasma ADMA, symmetric dimethylarginine (SDMA), malondialdehyde (MDA), glutathione peroxidase (SeGSHPx), C-reactive protein (CRP) were mea-sured before transplantation and on Days 1, 3, 7, 14, and 28 posttransplantation. The brachial artery flow mediated dilatation (FMD) was studied before transplantation and on the 28th day after the transplantation. Results Serum levels of ADMA,SDMA,MDA and CRP were significantly increased, and the activities of nitric oxide (NO) and SeGSHPx were decreased in uremic patients compared with age matched healthy subjects (all P＜0.01). Serum levels of ADMA,SDMA,MDA and CRP decreased while the activities of NO and SeGSHPx increased significantly at the first day after the transplantation (all P＜0.01). The decrement of plasma SDMA normalized on the 28th day (P＞0.05). The FMD was lower in the patients than the control group (P＜0.01) and improved significantly on the 28th day of posttransplantation (P＜0.05). Serum levels of ADMA were positively correlated with MDA (r=0.412, P＜0.01;r=0.342,P＜0.01) and negatively correlated with the values of SeGSHPx (r=-0.345, P＜0.01;r=-0.315, P＜0.01) and FMD (r=-0.452,P＜0.01;r=-0.416,P＜0.01) both before and after kidney transplantation. Conclusion The level of serum ADMA is associated with endothelial function improvement in uremic patients both before and after kidney transplantation.
