[Objective]To explore the clinical indication and effectiveness of anterolateral mini-incision for the total hip replacement (THR).[Method]A retrospective analysis of the 34 cases of anterolateral mini-incision was conducted from May 2002 to March 2005,among the patients 23 suffered from displaced femoral neck fractures and 11 suffered from femoral head aseptic necrosis.[Result]All the patients were followed up for 12～36 months with an average of 18 months.The obvious advantages of anterolateral mini-incision for the total hip replacement were as following:less blood loss in operation,less post-operative pain and complications,and early rehabilitation training,without cinch and subsidence in X-ray.Harris score was 92.1 point.[Conclusion]Anterolateral mini-incision for the total hip replacement can be used as an effective method to treat the patients who were extenuation,without abnormalities of hip joint,deossification and osteoporis.Appropriate incision combined with precise procedure can reduce the operative trauma and speed up functional recovery.

Objective: To demonstrate the influence of HMGB34367,a subfamily member of the high-mobility group protein B1(HMGB1),as a transcriptional factor of the ?-SMA gene expression.Methods: We cloned HMGB34367 cDNA from the fibrotic lung tissue of the Balb/C mouse treated with BLM by RT-PCR,sub-cloned it into a eukaryotic expression vector pcDNA 3.0 or pEGF-N2,and constructed a report plasmid,pDsRed-SMA,encoding red fluorescence(RFP) driven by ?-SMA promoter.Following the co-transfection of pDsRed-SMA and HMGB34367-pcDNA3.0/ pEGF-N2-HMGB34367 in the cultured 16HBE cells,we tested the expression of the RFP in the absence and presence of TGF?1 by fluorescence microscopy.After the transfection of HMGB34367-pcDNA3.0,the nucleus extracts from the transfected cells were subjected to electrophoretic mobility shift assay(EMSA) for the detection of the binding activity of HMGB34367 with ?-SMA promoter CarGB motif.RT-PCR was performed for the evaluation of the ?-SMA gene expression in the cells.Results: The over expression of HMGB34367 activated the ?-SMA promoter and enhances the expression of the ?-SMA gene.An increased binding activity of HMGB34367 with CarGB motif was detected by EMSA in the transfected cells.Conclusion:HMGB34367,a member of HMGB1 family,could act as a transcription factor for the transcriptional activation of the ?-SMA gene,which may play an important role in the development of lung fibrosis.

BACKGROUND:In resent year,as the biological materials improving,all kinds of sutures are used widely in clinic. It is an important problem how to select the exact one for surgeon. OBJECTIVE:To compare the effect of antibacterial and poly (p-dioxanone) absorbable sutures (PDS) in abdominal wall incision. DESIGN,TIME AND SETTING:A contrast observation was performed at the Department of General Surgery,the Second Affiliated Hospital of Shantou University Medical College between January 2005 and August 2007. PARTICIPANTS:A total of 450 laparotomy patients,including 230 males and 220 females aging 18-78 years with the mean age of (40?9) years were collected in this study. METHODS:The 450 patients were randomly divided into three groups,including the antibacterial absorbable suture (AAS; abdominal wall incision except the skin was successively sutured with triclosan-coated antibacterial absorbable suture),PDS group (abdominal wall incision except the skin was successively sutured with PDS suture),and control group (abdominal wall incision was treated with common suture),with 150 cases in each group. All patients were followed up for 12-24 months. MAIN OUTCOME MEASURES:The visual analogue scale (VAS; point 0:indolence; point 10:severe pain),the incision heal classification and complications including incisional infection,rejection reaction,scar formation,incisional disruption and incisional hernia. RESULTS:A total of 450 cases were included in the final analysis. The VAS in the AAS group and the PDS group were significantly lower than control group (P

Reversed phase high performance liquid chromatography with diode array detector was employed for simultaneous determination of five main index components and specific chromatograms analysis in Xiaochaihu granules with a linear gradient elution of acetonitrile-water (containing 0.1% phosphoric acid) as mobile phase. The results showed that five main index components (baicalin, baicalein, wogonoside, wogonin, enoxolone) were separated well under the analytical condition. The linear ranges of five components were 0.518 - 16.576, 0.069 - 2.197, 0.167 - 5.333, 0.009 - 0.297 and 0.006 - 0.270 mg x g(-1), respectively. The correlation coefficients were 0.999 9, and the average recoveries ranged from 95% to 105%. Twelve common peaks were selected as the specific chromatograms of Xiaochaihu granules with baicalin as the reference peak. There were good similarities between the reference and the ten batches of samples. The similarity coefficients were no less than 0.9. The analytical method established is highly sensitive with strong specificity and it can be used efficiently in the quality control of Xiaochaihu granules.

BACKGROUND:The diagnosis of osteoporosis depends upon the bone mineral density T-score of ≤ -2.5 standard deviation or brittle fractures. Bone mineral density measurement combined with vertebral fracture assessment might prevent the missed diagnosis of osteoporosis due to bone mineral density evaluation alone, and improve the diagnosis rate of osteoporosis.
OBJECTIVE:To evaluate the effect of bone mineral density measurements combined with vertebral fracture assessment for the diagnosis of osteoporosis.
METHODS:Bone mineral density measurements of proximal femur and vertebral fracture assessment for lateral thoraco-lumbar images were consecutively done for 217 postmenopausal women who aged ≥ 50 years. The rate of osteoporosis diagnosed with bone mineral density T score was compared with that diagnosed with bone mineral density combined with vertebral fracture assessment. The effects of bone mineral density on the vertebral fracture were analyzed.
RESULTS AND CONCLUSION:92 (42.4%) patients had bone mineral density T score ≤ -2.5, which met the threshold for diagnosis of osteoporosis. 102 (47.0%) patients had osteopanic (-1>T>-2.5) and 23 (10.6%) had normal range of bone mineral density. 158 patients had no vertebral fractures and 59 (27.2%) patients had 101 vertebral fractures. The vertebral fracture rate was 21.6%in the patients with bone mineral density T> -2.5 and 34.8%in the patients with bone mineral density T ≤ -2.5, with significant differences (P<0.05). Bone mineral density in combination with vertebral fracture assessment for the diagnosis rate of osteoporosis was up to 54.8%, which was significantly higher than the rate diagnosed with only bone mineral density (12.4%;P=0.01). Bone mineral density measurement combined with vertebral fracture assessment improves the diagnosis of osteoporosis for postmenopausal women.

Objective To observe any therapeutic effect of proprioception training and intra-articular injection of sodium hyaluronate on knee osteoarthritis (KOA) in the elderly.Methods Forty-five patients with KOA were randomly divided into a treatment group (23 cases) and a control group (22 cases).The arthritic knees of both groups were treated with sodium hyaluronate injections,but the patients in the treatment group also received proprioception training.Before treatment,and after 5 weeks and 3 months of treatment,knee function was assessed against Lysholm's assessment standard.Results There was no significant difference in the average Lysholm scores of the two groups before treatment.After 5 weeks and 3 months the patients in each group scored significantly higher than before treatment.After 3 months the average score of the treatment group was significantly higher than that of the control group.Conclusion Proprioception training and sodium hyaluronate injections together constitute a useful method to treat KOA in elderly patients.

Objective To explore the therapeutic effect and application value of the self-made spinal positioning equipment and percutaneous pedicle screw fixation system in the treatment of thoracic and lumbar fracture. Methods To determine the fractured vertebra and pedicle screws entrance point with spinal positioning equipment, 67 patients with thoracic and lumbar fractures were performed percutaneous pedicle screw fixation by using self-made percutaneous pedicle screw fixation system. By contrasting the perioperative indicators, and imaging indicators, to evaluate the therapeutic effect and application value of the system. Results For the spinal positioning equipment, the location time were (15.85±2.45) min and the location accuracy were 95.03%±3.27%. But for the open reduction internal fixation, the location time were (35.46±5.39) min and the location accuracy were 94.02%±2.95%. There was no significant difference in location accuracy, but were significant differences in location time (P＜0.05). Percutaneous pedicle screw fixation had the same effect on three sides with open reduction internal fixation in vertebral height restore,kyphosis deformity and correction and lumbar spinal stenosis's correction. The perioperative indicators of the preoperative and postoperative grope had significant difference (P＜0.05). There were significant differences in all perioperative indicators between the percutaneous pedicle screw fixation and the open reduction internal fixation (P＜0.05). Conclusion The spinal positioning equipment is helpful to determine the fractured vertebra and pedicle screws entrance point accurately and reduce the radiation. The percutaneous pedicle screw fixation system has the advantage of convenient manipulation and accurate implantation. The system can not only reduce surgical damage and post-operation reaction but also make patients recover quickly and face less complications.
