Objective:To explore and study the clinical values of CT and MRI in the diagnosis of spinal trauma. Methods: One hundred patients with spinal trauma in our hospital were selected as the study objects and randomly divided them into 2 groups, 50 cases in each group. The control group was diagnosed by CT, the experimental group was diagnosed by MRI. Results: The efficacy of CT(control group) on fracture line and fracture flat shift was better than experimental group, but in the aspect of spinal cord injury, ligamentous injury and soft tissue injury, experimental group(MRI) was more sensitive than control group(x2=4.0, P<0.05), differences between 2 groups were statistically significant. Conclusion:Every coin has 2 sides, so as to applying CT and MRI in the diagnosis of spinal trauma, but the accuracy to overall spinal trauma of experimental group is higher. Furthermore, it can avoid misdiagnosing with spinal trauma that applying combined CT and MRI, it is worthy of being widely recommended in clinic.

Objective To investigate the causes and prevetion of urethral stricture after transurethral resection of the prostate(TURP). Methods A retrospective analysis was carried out in 945 cases,who were treated by TURP in our hospital during February 2002-February 2008.Among the cases,21 patients(aged 62 to 84 years with a mean of 72.4 years) developed urethral stricture in 3 weeks to 24 months after the operation.In the cases,anterior urethral stricture was detected in 13 patients(61.9%),posterior urethral stricture was found in 5(23.8%),and bladder neck contracture was diagnosed in 3(14.3%).Results The pateints were cured by simple urethral dilation(13,61.9%),urethroplasty(2,9.5%),urethroplasty plus urethral dilation(2,9.5%),transurethral resection(1,4.8%),or electroresection of the bladder neck(3,14.3%).The patients were followed up for 6 to 36 months(mean,13 months),during which,all the 21 cases recovered without recurrence.The rate of urethral stricture after TURP was 3.7%(18/483) during February 2002 to August 2005,which was significantly higher than that between September 2005 and February 2008(0.6%,3/462;?2=10.292,P=0.001).Conclusions Unskilled operation and short indwelling time of urethral catheter after the surgery are the major reasons for urethral stricture after TURP.Regular follow-up and early treatment are the keys to cure of the disease.

Objective To compare knowledge about hypertension between elderly Chinese urban patients with preferences for either traditional Chinese medicine (TCM) or Western medicine (WM).Methods Elderly (≥ 65 years old) patients with hypertension who prefer TCM treatment (n=112) or WM (n=126) were questioned about hypertension.Their answers were compared.Results Only 32.6% of participants correctly identified hypertension as a main risk factor of coronary heart disease and stroke,22.3% of patients answered that the main purpose of hypertension control was preventing cardiovascular disease.Other major reasons for these patients to seek medical treatment for their hypertension included:persuasion by physicians or their family members (21.6%),alleviating symptoms such as headache and dizziness (16.8%),lowering blood pressure without knowing specific reason (12.4%).The predictors for poor knowledge of hypertension were similar irrespective of preference for WM or TCM treatment,and included those with lower levels of education and older age.Television and newspaper (46.8%) were the most frequent sources of hypertension information for both groups.Among those who preferred TCM treatment,TCM has fewer side effects than WM and TCM cures disease while WM only alleviates symptoms were common beliefs held.Conclusion This study shows that knowledge of hypertension is similar among Chinese urban patients with preferences for either WM or TCM treatment and that misunderstandings about hypertension are common among the elderly patients.In order to control hypertension effectively,public health education is necessary.This should target those with a lower level of education and older age.

BACKGROUND:Basic fibroblast growth factor(bFGF)can promote production of collagen,fibronectin and matrix enzyme in healing wounds.However,dysregulation of this process,such as the abnormal coordination of cell proliferation,extracellular.matrix and neovasculadzation formation,or remodeling of the wound matrix will lead to excess accumulation of scar tissues.OBJECTIVE:To investigate effects of bFGF on normal skin wound healing and hypertrophic scar formation.METHODS:Normal and hypertrophic scar fibroblasts from tissue biopsies from 5 patients who underwent plastic surgery for repairing hypertrophic scars were isolated and cultured.The expressions of collagen,fibronectin and protein synthesis were detected by RT-PCR and ELISA.The mitochonddal membrane potential changes were measured using JC-1 staining and flow cytometry.Simultaneously,adenosine tdphosphate(ATP)levels were determined by chemiluminescence method.The effects of bFGF on these indexes of normal and hypertrophic scar fibroblasts were observed.RESULTS AND CONCLUSION:Hypertrophic scar fibroblasts become slower after being exposed to bFGF,which selectively inhibited type Ⅰ collagen production in hypertrophic scar fibroblasts(P<0.05).Although bFGF inhibited type]collagen production,it had no effect on type Ⅲ collagen expression in both normal and hypertrophic scar fibroblasts.However,fibronectin expression in the normal fibroblasts was up-reguleted after bFGF treatment(P<0.05).In addition,the mitochonddal membrane potential tended to depolarization,although no statistical difference,in hypertrophic scar fibroblasts treated with bFGF(10 or 100 μg/L).bFGF treatment increased the cellular ATP levels in the normal fibroblasts,while there were no significant alterations in the hypertrophic scar fibroblasts over a treatment of bFGF(10 or 100 μg/L,P<0.05).The results suggest that there are differential effects and mechanisms on the skin fibroblasts with bFGF treatment in normal wound healing and hypertrophic scar formation.

BACKGROUND: Runx2 plays a central role in osteogenic differentiation, which is of important significance in new bone formation.OBJECTIVE: To observe the effect of Runx2 over-expression on osteogenic differentiation of human umbilical cordblood mesenchymal stem cells.METHODS: Runx2 was generated by RT-PCR and the recombinant adenovirus (pAd-Runx2) was constructed. The viraltiter was determined by air dilution method. After being transfected into human umbilical cord blood mesenchymal stemcells, the green fluorescence was observed under fluorescence microscope. Real-time fluorescent quantitative PCR andwestern blot were used to detect mRNA expression changes of osteogenesis related genes, Runx2, OCN, BMP-2, ALP,in human umbilical cord blood mesenchymal stem cells at 1, 3, 7 and 14 days after transfection.RESULTS AND CONCLUSION: The recombinant adenovirus was successfully constructed and the titer was1.7×1010 pfu/L. After infection by pAd-Runx2, human umbilical cord blood mesenchymal stem cells expressed greenfluorescence protein clearly under the fluorescence microscope. Cells in the transfected group differentiated intoosteoblast-like cells, and those in the control group stayed the same as pre-infected. The expression of Runx2, OCN,BMP-2 and ALP in the transfected group increased over time to some extent, but these changes were not detected in thecontrol group. These findings indicate that Runx2 over-expression can promote the osteogenic differentiation of humanumbilical cord blood mesenchymal stem cells.

ObjectiveTo investigate the effect of anisodamine on the expression of connexin 43 (Cx43) in swine ventricular myocardium after resuscitation from cardiac arrest.Methods The experiment was conducted on healthy pigs, and they were randomly divided into three groups, namely sham group, epinephrine group (control group) and anisodamine group (experimental group, animals were resuscitated combined with injection of 0.4 mg/kg of anisodamine), with 5 pigs in each group. Model of ventricular fibrillation was reproduced by alternating current challenge, and cardiopulmonary resuscitation (CPR) was performed 8 minutes after cardiac arrest. Left ventricular myocardium was harvested at 24 hours after restoration of spontaneous circulation. The expression and distribution of Cx43 were observed by immunofluorescence, Cx43 mRNA expression was assessed with reverse transcription-polymerase chain reaction (RT-PCR), and the protein expressions of Cx43 and phosphorylation of Cx43 (p-Cx43) were analyzed by Western Blot.Results The positive expression of Cx43 in ventricular muscle was distributed uniformly, mostly at the end-to-end linkage of myocardial cells, with a few side-to-side linkage in sham group. The positive expression of Cx43 in control group was significantly weaker than that in the sham group, and the signal intensity was significantly declined (4.35±2.10 vs. 10.02±3.66,P< 0.01). The positive expression of Cx43 at the end-to-end linkage and side-to-side linkage was irregular in experimental group, and the signal intensity was obviously higher than that in the control group (7.91±2.54 vs. 4.35±2.10,P< 0.05), but it was significantly weaker than that in the sham group (7.91±2.54 vs. 10.02±3.66,P< 0.05). For control group and experimental group, the Cx43 mRNA and protein expressions were significantly lower than those of the sham group [Cx43 mRNA (A value): 0.32±0.05, 0.32±0.03 vs. 0.48±0.07; Cx43 protein (A value): 0.43±0.03, 0.50±0.07 vs. 0.65±0.04, allP< 0.01], and there were no significant differences between experimental group and control group (allP> 0.05). The p-Cx43 protein expression of control group was significantly lower than that of the sham group (A value: 0.22±0.03 vs. 0.37±0.06,P< 0.01), and it was significantly higher in the experiment group than that in the control group (A value: 0.29±0.07 vs. 0.22±0.03, P< 0.01), but there was no significant difference with the sham group (P> 0.05). No significant difference in p-Cx43/Cx43 was found among sham, control, and experiment groups (0.57±0.09, 0.51±0.05, 0.58±0.06, all P> 0.05).ConclusionAnisodamine can improve the abnormal expression of Cx43 in ventricular muscle of pigs with cardiac arrest, which may be related to the protection effect of anisodamine on cardiac conduction.
