OBJECTIVETo analyze the clinical effects of short-segment posterior pedicle screw combined with transpedicle vertebral bone grafting in treating thoracolumbar burst fractures.

METHODSFrom March 2008 to March 2013, 62 patients with thoracolumbar burst fractures were treated with short-segment posterior pedicle screw combined with transpedicle vertebral bone grafting. Including 40 males and 22 females, the age from 17 to 65 years old with an average of 38 years. According to AO classification, 34 cases were type A3.1, 7 cases were type A3.2 and 21 cases were type A3.3. Load-sharing scores were from 4 to 6 points with an average of 5.4 points. According to ASIA grade, 2 cases were grade C, 5 cases were grade D and 55 cases were grade E. Preoperative, postoperative at 3 d and final follow-up, the Cobb angle, the relative height of anterior vertebral body and the encroachment rate of spinal canal were measured by X-ray films and computed tomography (CT) scan, meanwhile, the information of bone healing and spinal nerves recovery were observed.

RESULTSAll patients were followed up from 11 to 14 months with an average of 12.2 months. The duration of removing internal fixation were from 9 to 13 months (averaged, 11.5 months). One suffered from infection and was cured by debridement. Two cases had mild pain of back. At 6 months after operation, according to ASIA grade to evaluate never function, 1 case was grade C, 3 cases were grade D and 58 cases were grade E. X-ray and CT showed the fractures obtained good union at final follow-up. The Cobb angle, the relative height of anterior vertebral body and the encroachment rate of spinal canal had obviously improved at 3 days after operation (P<0.05); but there was no significant differences between postoperative at 3 d and final follow-up (P>0.05).

CONCLUSIONShort-segment posterior pedicle screw combined with transpedicle vertebral bone grafting is an effective method to treat thoracolumbar burst fractures. It can reduce the loss of postoperative correction and prevent the internal fixation failure.

Objective To observe and scale knee joint space of the patients who suffered adults' Kaschin-Beck disease (KBD) in Shangzhi City of Heilongjiang Province in order to acquire basic knowledge for upcoming intervention trial. Methods Clinical test was proceeded in adults aged above 40 in Guanghui Village of Shangzhi City in 2007. In typical patients, bilateral knee X-ray was taken and knee joint space was scaled. Three points were chosen on inner and outer epicondyle of each knee and results were recorded. Results There were 307 peoples over the age of 40 in the village. Two hundred eighty-two accepted clinical test, in a rate of 91.9%. Eighty out of 282 suffered KBD, accounting for 28.4%. When the patients' condition became more serious, measurements from flank, middle, inside points on outer epicondyle of joint space presented a narrowing trend [degree Ⅰ: (5.85±0.17), (4.84±0.17), (4.36±0.18)mm; degree Ⅱ: (5.11±0.43), (4.24±0.34), (3.48±0.28)nun; degree Ⅲ: (3.59± 0.78), (3.10±0.56), (2.14±0.62)mm; Fflank,middle,inside= 6.547,5.372,10.302, all P < 0.05], but those on inner epicondyle of joint space did not[degree Ⅰ:(3.66±0.17), (3.47±0.17), (3.73±0.18)mm; degree Ⅱ:(3.55± 0.34), (3.54±0.29), (4.35±0.35)mm; degree Ⅲ: (3.19±0.72), (3.92±0.66), (4.51±0.72)ram; Finside,middle,flank= 0.351,0.356,1.883, all P > 0.05]. Joint space < 5.00 mm were found in 618, among which 363 were measured on inner epieondyle, obviously greater than those measured on outer epicondyle of joint space(255), the difference being statistically signifieant(χ2=9.59, P<0.05). Conclusions Adult cases of KBD occur in Guanghui Village. Knee joint space of adult patients narrows obviously, the more serious, the narrower, especially occurring more obviously on outer epicondyle, but frequently on inner epicondyle.

Objective · To compare the prevalence of tobacco advertisement before and after implementation of the new edition of Advertising Law of the People's Republic of China and evaluate the effects of implementation of the new Advertising Law. Methods · Tobacco sales places, public places, and streets in Shanghai were randomly selected to observe tobacco advertisement and complete the survey. The survey was carried out in 10 districts of Shanghai in June 2015 with 10 tobacco sales places selected in each district, and in 4 districts of Shanghai in June 2016 with 25 tobacco sales places selected in each district. Sales places included convenient stores, tobacco stores, supermarkets, and kiosks. In addition, public transport waiting points, public transport vehicles, hospitals, shopping centers, restaurants, bars, and Internet cafes were selected into survey in 2016. Results · In 2016, the proportion of tobacco sales places having tobacco advertisement was lower than that in 2015, but the proportion of tobacco promotion behaviors was higher. In 2016, 128 public places and streets were investigated and only 1 had outdoor tobacco advertisement. Conclusion · The new edition of Advertising Law has significant effect on controlling tobacco advertisement, but tobacco sales places still have tobacco advertisement with various disguised promotion forms. Tobacco sales places have diversified business styles and minors often enter these places. It is recommended that a clear definition of disguised forms of tobacco advertisement should be made, tobacco advertisement at tobacco sales places needs to be supervised, the release of tobacco advertisement should be strictly reviewed, and existing tobacco advertisement should be severely punished, so as to prevent minors from exposing to tobacco advertisement and information luring smoking.

BACKGROUNDCurrently, there are still divergent opinions about the mechanisms of the impaired neovascularization in diabetic subjects. Due to the remarkable therapeutic effect of angiotensin-converting enzyme inhibititors (ACEIs) on the reduction of blood pressure and the protection of target organs, the clinical application of this kind of drugs is very widespread. However, it is still not clear about the role and related molecular pathway of this kind of drugs in the limbs' postischemic revascularization. It is of major therapeutic importance to resolve these questions. This study aimed to investigate the reasons of the impaired angiogenesis in the hind limbs of rats with diabetic ischemia, the role and related molecular mechanisms of ACEI in postischemic revascularization.

METHODSHind limbs ischemia was induced in diabetic rats by right femoral artery excision. Diabetic rats were randomly allocated to one of the following treatments for 4 weeks: ACEI by perindopril; perindopril in combination with a nitric oxide synthase (NOS) inhibitor; perindopril in combination with bradykinin (BK)-B1 receptor (B1R) antagonist or saline. The differences of angiogenesis, the mRNA and protein expression of endothelial nitric oxide synthase (eNOS), vascular endothelial growth factor (VEGF) and basic fibroblast (bFGF), constitutive nitric oxide synthase (cNOS) activity and nitric oxide (NO) content were observed after treatment.

RESULTSIn non-ischemic hind limbs, no significant changes in capillary density, or the mRNA and protein expression of eNOS, VEGF and bFGF, or the NO content and the cNOS activity were observed among all groups. On the contrary, in ischemic hind limbs, the capillary density in diabetic rats decreased by 27% when compared with the control rats, so did the mRNA and protein expression of eNOS, VEGF and bFGF, or the NO content and the cNOS activity (P < 0.05). The capillary density was increased by 1.65-fold in the perindopril treatment group in reference to untreated diabetic rats. Moreover, administration of perindopril enhanced the mRNA expression of eNOS, VEGF, and bFGF by 1.45-, 1.44-, and 1.33-fold, increased the protein content of the above indices by 1.55-, 1.30- and 1.50-fold compared with the untreated diabetic rats respectively. Perindopril also increased NO content and cNOS activity to 1.33- and 1.38-fold of that in untreated diabetic rats. The combination of BK-B1R antagonist significantly decreased the above indices (P < 0.05). In contrast, the combination of NOS inhibitor decreased the expression of eNOS and bFGF, the NO content and the cNOS activity, while the expression of VEGF did not change.

CONCLUSIONSDiabetes mellitus reduces the neovascularization, related growth factors expression and activity in the diabetic rat ischemic legs model. Treatment of perindopril improves postischemic revascularization. This effect is mediated, at least in part, by the BK-B1R-related pathway, and the activation of VEGF/eNOS/bFGF signals may be involved in the pro-angiogenic effect.

OBJECTIVETo investigate the expression of FSCN1 in human epithelial tumors and their clinical significance.

METHODSFSCN1 expression was examined immunohistochemically in specimens of human epithelial tumors, including 26 cases of lung cancer, 33 cervical cancer, 22 ovarian cancer, 38 esophageal cancer, 24 pancreatic cancer, 23 gastric cancer, 29 laryngocarcinoma, 17 primary hepatocellular carcinoma, 34 colorectal cancer, 33 breast cancer, 24 nasopharyngeal carcinoma and their corresponding normal tissues.

RESULTSThe positivity rates of FSCN1 expression in epithelial tissues and epithelial tumors were 6.3% (5/80) and 58.7% (178/303), respectively. FSCN1 showed higher expressions in cervical cancer, ovarian cancer, esophageal cancer, pancreatic cancer, gastric cancer, laryngocarcinoma, colorectal cancer, breast cancer and nasopharyngeal carcinoma, but lower or no expression in the corresponding normal tissues (P<0.05). In gastric cancer and nasopharyngeal carcinoma, the edges of the tumors were more strongly stained for FSCN1 than the interior of the tumor.

CONCLUSIONFSCN1 expression is significantly upregulated in human epithelial tumors in close correlation with tumor occurrence and progression.
