OBJECTIVETo explore the clinical effects of Dynesys system for the treatment of multiple segment lumbar degenerative disease.

METHODSA total of 28 patients with lumbar degenerative disc disease treated with Dynesys system from December 2008 to May 2011 were retrospectively reviewed. There were 16 males and 12 females, aged from 27 to 75 years old with an average of 49.1 years. Thirteen patients with multiple segmental lumbar intervertebral disc protrusion, including L3-L5 in 7 cases, L2-L4 in 1 case and L4-S1 in 5 cases. Fifteen patients with multiple segmental lumbar spinal stenosis, including L3-L5 in 10 cases, L4-L5 in 4 cases and L2-S1 in 1 case. The symptoms of lumbago and (or) intermittent claudication in all patients were treated with conservative treatments for more than 6 months and these methods did not work. Visual analogue scale (VAS) was used to analyze the lumbar and leg pain, imaging data were used to measure the intervertebral space height and intervertebral motion of fixed segment and upper adjacent segment, Oswestry Disability Index (ODI) was used to evaluate the clinical effect.

RESULTSAll operations were successful and the patients were followed up from 38 to 65 months with an average 50.6 months. At final follow-up, ODI and VAS of the low back pain and leg pain were (25.10±6.52)%, (1.25±0.70) points and (1.29±0.89) points, respectively and were decreased compared with preoperative (P<0.05). Postoperative intervertebral space heights were increased and intervertebral motions were decreased in fixed segment compared with preoperative (P<0.05). There were no significant differences in intervertebral space heights and intervertebral motions of upper adjacent segment between preoperative and postoperative (P>0.05).

CONCLUSIONDynesys system may obtain long-term clinical curative effect in treating multiple lumbar degenerative disease. It can partially preserve the intervertebral motions of the fixed segments, have little effect on adjacent segments. The long-term clinical effect of Dynesys still need longer time follow-up observation.

Objective To investigate the diagnosis and treatment of idiopathicgranulomatous mastitis.MethodsThis study was to retrospectively review the clinical presentation,radiological investigation,histopathological features,treatment and outcome of idiopatbic granulomatoos mastitis of women presenting to Xuanwu Hospital between January 2002 and June 2010.ResultsTwenty-four patients with a mean age of 34.5 years presented with a diagnosis of idiopathic granulomatous mastitis.Patients presented with a palpable breast lump,breast abscess,fistula formation in different periods of the disease; the role of radiological imagings was found to be limited in differentiating idiopathic granulomatous mastitis from other inflammatory and maliguant conditions of the breast.All patients underwent a surgical procedure as the main treatment; in the form of excision or incision and drainage of the breast lesions. Mean follow-up was 47.38 ( range 6-96 ) months with recurrence in 3(12.5％) patients.ConclusionsIdiopathic granulomatous mastitis presents clinically with a palpable breast lump.The diagnosis is often only made histopathologically after surgical excision or core biopsy.Wide excision of the lesions or incision and drainage of the lesion are the main treatment modalities.

In the study, the effects of Panax notoginseng saponins (PNS) on alveolar epithelial to mesenchymal transition (EMT) and extracellular matrix degradation were observed in a type of human alveolar epithelial cell, A549 cells, stimulated by TGF-beta1. Firstly, MTT method was applied to evaluation of cellular proliferation and found that PNS from 12.5 mg x L(-1) to 200 mg x L(-1) dosage could not inhibit significantly cellular proliferation. Then, cells were divided into five groups, normal group, TGF-beta1 group, TGF-beta1 + 50 mg x L(-1) PNS group, TGF-beta1 + 100 mg x L(-1) PNS group and TGF-beta1 + 200 mg x L(-1) PNS group. Normal cells were not stimulatec by TGF-beta1; TGF-beta1 cells were only stimulated by TGF-beta1 and the other cells were stimulated by TGF-beta1 with different doses of PNS, respectively. After stimulation, cells and supernatants were collected for assays. Cellular roundness was applied to quantitative evaluation of morphological change. Immunocytochemistry was applied to examine E-cadherion, a-SMA and FN proteins expression in the cells. Enzyme linked-immunosorbent assay was applied to MMP-9 and TIMP-1 levels. The results showed that EMT of A549 cells was induced by TGF-beta1, showing significant change of roundness, E-cadherion, alpha-SMA and FN (P < 0.05, P < 0.01). Compared to TGF-beta1, PNS significantly inhibited the changes of roundness (P < 0.05), FN and alpha-SMA (P < 0.05, P < 0.01) and not significantly inhibited the change of E-cadherion. Furthermore, MMP-9 levels were significantly increased by TGFbeta1 stimulation (P < 0.05), without significant change of TIMP-1. Compared with TGF-beta1, PNS could significantly increase MMP-9 level (P < 0.05) and decrease TIMP-1 levels (P < 0.05, P < 0.01). In conclusion, PNS could inhibit alveolar epithelial cell EMT induced by TGF-beta1, with increase of extracellular matrix degradation ability, which showed anti-fibrosis of lung ability.

OBJECTIVETo investigate the clinical significance of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) in the treatment of spinal tuberculosis.

METHODSSixty-seven patients (41 males and 26 females, ranging in age from 23 to 61 years) with active spinal tuberculosis in our hospital (from Mar. 2004 to Mar. 2007) were included in this study. The tuberculosis focus were located either in cervical spine, thoracic spine or in lumbar spine. After 4 to 6 weeks anti-tuberculosis chemotherapy, all the patients underwent one-stage operation (focus debridment) and auto-bone graft combined with internal fixation. Blood test for ESR and CRP were carried out at different times before and after operation.

RESULTSThe average ESR was (79.4 +/- 35.6) mm/h, and the average CRP was (44.3 +/- 17.5) mg/L before chemotherapy, indicating active tuberculosis focus. After 4 to 6 weeks chemotherapy, the average ESR was (45.3 +/- 21.0) mm/h,and the average CRP was (26.7 +/- 11.8) mg/L, the differences were statistically (P < 0.05), and the clinical symptoms of spinal tuberculosis relieved in all patients. Four weeks after operation, the average ESR dropped to (42.8 +/- 16.5)mm/h, the average CRP dropped to (23.8 +/- 10.0) mg/L statistically (P < 0.05). Eight weeks after operation, the average value of ESR and CRP were at normal level in 47 cases, indicating inactive tuberculosis focus. Focus healing was achieved in 65 patients after short-term chemotherapy.

CONCLUSIONThe level of ESR and CRP are high in active spinal tuberculosis and low when focus controlled. ESR and CRP are reliable parameters in evaluation the treatment and prognosis of spinal tuberculosis.

OBJECTIVETo investigate the combined treatment with areola approach for capsular contracture after breast augmentation with implants.

METHODSFrom Feb. 2005 to Jun. 2011, 94 cases (168 sides) with Baker III and IV capsular contracture after breast augmentation with implants were treated with areola approach. The implants cavity was recreated, with or without removal of capsule. The implants were reimplanted behind pectoralis major or breast at the second stage in some patients.

RESULTS46 cases were followed up by clinic visit and the others were followed up by telephone for 6-37 months, with an average of 9.9 months. The capsular contracture was relapsed in 2 cases as Baker III and 1 case as Baker IV. All the other breasts got a good appearance with good soft texture and feeling. No hematoma, infection, implants rupture, breast ptosis or implant displacement happened.

CONCLUSIONSCombined treatment with areola approach has a good therapeutic effect for capsular contracture after breast augmentation with implants. The breast appearance is satisfactory with low occurrence of capsular contracture.

AIM: To investigate antioxidant activities and life span prolonging effects of the extracts from the roots of Incarvillea younghusbandii Sprague, and to study the correlations between these activities and the polar intensity of the extracts. METHOD: Five extracts (IYS1, IYS2, IYS3, IYS4 and YS5) with different polar intensity were prepared. Antioxidant activities in vitro were determined by LPO inhibitory and free radicals scavenging experiments. Life span prolonging effects in vivo were evaluated by feeding Drosophila melanogaster. RESULT: Total phenolic content in extracts were solvent-dependent and decreased in the order of IYS4 > IYS1 > IYS3 > IYS5 > IYS2. Organic extracts (IYS1 and IYS4) showed excellent LPO inhibitory activity, O(2)(· -) and ·OH scavenging activity compared to ascorbic acid (or benzoic acid, or BHT), while aqueous extracts (IYS2, IYS3 and IYS5) did not. The antioxidant activities (in vitro) were solvent dependent and decreased in the order of IYS4 > IYS1 > IYS3 > IYS5 ≥ IYS2. Drosophila melanogaster was fed with organic extracts (IYS1 or IYS4) at 5.0 mg mL(-1). The mean life span were increased by 24.4% (IYS1) or 23.0% (IYS4) in female and 15.3% (IYS1) or 16.9% (IYS4) in male; the maximum life span were increased by 8.4% (IYS1) or 11.2% (IYS4) in female and 9.7% (IYS1) or 15.8% (IYS4) in male, and the survival curves were significantly shifted to the right after fifteen days in both sexes survival period. Feeding aqueous extracts (IYS2, IYS3 or IYS5) at 5.0 mg·mL(-1), the significant life span prolonging effects were not achieved. The life span prolonging effects of the extracts were solvent-dependent and decreased in the order of IYS4 ≥ IYS1 > IYS3 > IYS2 > IYS5. CONCLUSION Extracts from the roots of Incarvillea younghusbandii Sprague showed excellent antioxidant activities and significant life span prolonging effects in Drosophila melanogaster. Positive correlations existed between the antioxidant activities and total phenolic content. Life span prolonging effect was positively correlated with the total phenolic content or antioxidant activities. The extracts possess better life span prolonging effect in females than in males.

OBJECTIVE: To explore the effect of Twist gene on the migration and invasion of human gastric carcinoma cells. METHODS: MKN28 cells, a human gastric carcinoma cell line, were transfected with PcDNA3.1-Twist plasmid by lipofectamine transfecting technique. The transfected cells were selected with geneticin. Expressions of Twist,ecadherin and vimentin protein were detected by Western blot in cells transfected Twist gene. Matrigel invision chambers were performed to analyse the cell migration and invasion. RESULTS: MKN28 cells transfected with PcDNA3.1-Twist plasmid showed stronger intracellular expression of Twist protein than MKN28 cells transfected with PcDNA3.1 and MKN28 cells without transfection. The expression of ecadherin protein in MKN28 cells transfected with PcDNA3.1-Twist plasmid was significantly decreased compared with that in MKN28 cells transfected with PcDNA3.1 and MKN28 cells without the transfection. However, The expression of vimentin protein in MKN28 cells transfected with PcDNA3.1-Twist plasmid was significantly increased compared with that in MKN28 cells transfected with PcDNA3.1 and MKN28 cells without transfection. The migration and invasion ability of Twist+ - MKN28 cells were stronger than that of MKN28 cells transfected with PcDNA3.1 and MKN28 cells without transfection. CONCLUSION Twist gene may promote the migration and invasion ability of gastric carcinoma cells through epithelial mesenchymal transition.
