Objective To investigate the radiographic characteristics of degenerative lumbar scoliosis (DLS) and its relationship to osteoporosis. Methods 229 cases (83 males, 146 females) of DLS from January 1998 to June 2005 were reviewed. The mean age was 56.8 years (ranged from 40 to 74 years). The Cobb angle and vertebral stability in coronal plane were measured in anteroposterior radiographs and the changes of lordosis in sagittal plane were observed in lateral radiographs. The bone mineral density(BMD) and T-Score of lumbar spine (L2-L4) were measured using Dual Energy X-ray Absorptiometry. Results The mean Cobb angle is 9.45??4.79?, 151 cases(66%) with the angle less than 10?, 60 cases (26%) with 10?-20?, and 18 cases (8%) with more than 20?. Right side scoliosis were found in 52% (120 cases), left side in 48% (109 cases). 159 cases (69%) companied with gradeⅠ(Nash-Moe) vertebra rotation, 54 cases (24%) with grade Ⅱ. And the vertebra rotation was most evident on scoliosis apex. There were 20 cases (9%) with more than 4 mm lateral translation between the lumbar vertebrae which were usually the apex vertebrae with the most degenerative changes. The physical lordosis decreased in most cases in which 16 cases (7%) developed lumbar or thoracolumbar kyphosis. And the kyphosis degree was not relevant to scoliosis Cobb angle. The mean T-Score of BMD measurement was -1.88?0.17, which was -1.49?0.14, -2.56?0.24, -2.89?0.50 for the groups of with Cobb angle 20? respectively. There were 153 cases (67%) with T10?), and 98 cases (43%) with T

The purpose of this study was to observe whether HBV can infect HSC in vitro. LX-2 cells, the human activated HSC cell line, were incubated with human serum containing HBVDNA at final concen-trations from 0.01 to 10 copies/cell and harvested after 24,48 and 72 hours. Hepatitis B surface antigen (HBsAg) and hepatitis B core antigen(HBcAg) were detected by lmmunohistochemistry dyed by DAB. By Immunohistochemistry, no positive particles in LX-2 cells, a few of dark brown particles (HBsAg and HB-cAg) were found in cytoplasm and nucleoli of HepG2.2. 15 cells,a lot of clark brown particles were found in liver biopsies of patients with chronic hepatitis B. In vitro, there was no evidence that HBV can infect and express antigens in LX-2 cells.

Objective To evaluate the nighttime blood pressure(BP) control status of hypertensive Chinese chronic kidney disease (CKD) patients and related risk factors.Methods This cross-sectional study enrolled 337 hypertensive CKD in-patients.The clinical and ambulatory BP monitoring (ABPM) data were retrieved from the electronic database of the hospital.High ambulatory BP were defined as ＞130/80 mmHg (average 24-hour BP) and ＞135/85 mmHg (daytime)/＞120/70 mmHg (nighttime),respectively.Multivariable analysis was used to evaluate the risk factors for lack of nighttime BP control and circadian rhythm.Results There were 38.6％ of the whole population had average 24-hour BP controlled.But only 22.8％ of them achieved nighttime BP control,which was far less than the 50.7％ of daytime BP control (P ＜ 0.01).Even among those patients who achieved average 24-hour BP control shown by ABPM,there were still 44.6％ of them with uncontrolled nighttime BP.Multiple analyses showed urinary protein excretion (OR:1.151,95％CI:1.035-1.279) was independent risk factor for lack of nighttime BP control.About 80％ of patients presented with nondipping BP pattern,among whom 37.3％ were presented with reverse-dipper pattern.Lack of nighttime BP control was independent risk factor for lack of normal circadian rhythm (both P＜0.001).Conclusions Lack of nighttime BP control was common in hypertensive CKD patients and contributed to the abnormal circadian rhythm.ABPM should be performed more commonly in clinical practice to help nighttime BP control in the future.

OBJECTIVE: To investigate the classification and distribution of external nasal fracture, and its influence to the nasal septum. METHOD: We randomly chose 60 patients who received nasal CT scan because of nasal trauma and diagnosed as external nasal fracture. We reviewed their CT data in PACS system with computer. RESULT: Of the 60 cases of nasal trauma, 90 sides got external nasal fracture, among which 58 sides (64.4%) had only nasal bone fracture, 16 sides (17.8%) had only maxillary frontal process fracture, and 16 sides (17.8%) had both. Half of these 60 patients got unilateral external nasal fracture, among whom 14 patients (46.7%) had traumatic nasal septum deviation meanwhile. The other 30 patients suffered from bilateral external nasal fracture, among whom 26 patients (86.7%) had traumatic nasal septum deviation. The difference between these two groups was statistically significant (P < 0.01). Moreover, 24 patients got fracture of either nasal bone or maxillary frontal process, 11 of whom (45.8%) got traumatic nasal septum deviation at the same time. The other 36 patients suffered fracture of both these two bones, 29 of whom (80.6%) had traumatic nasal septum deviation. The difference between these two groups was statistically significant (P < 0.01). We classified the nasal bone fracture as below: 16 patients with only unilateral external nasal fracture belonged to Type I, of whom 15 patients (25.0%) were type Ia with nasal bone or maxillary frontal process fracture and 1 patient (1.7%) fell into type Ib with fracture occurred on both of these two bones at the same side. Four patients suffered bilateral external nasal fracture belonged to type II, among whom 2 patients (3.3%) belonged to type IIa with nasal bone or maxillary frontal process fracture and 2 patients fell into type IIb with fracture of both of these two bones at different sides. The other 40 patients (66.7%) belonged to Tpye III, who suffered external nasal fracture accompanied with traumatic nasal septum deviation. CONCLUSION Traumatic nasal septum deviation was extremely concomitant in patients with external nasal fracture. It will be better to perform external nasal reconstructive surgery and plasty of nasal septum deviation by using the endoscope within 1 month for the patients whose symptom were serious or who cared a lot about the appearance.

Objective:To investigate the inhibitory effect and mechanism of different doses of Xiao Chai Hu Tang on C6 glioma cells cultured in vitro. Methods:C6 glioma cells were inoculated in 96 holes,24 holes and 6 holes,each culture plate was divided into 4 groups:control group, low dose group, middle dose group and high dose group, when the cells covered the bottom of culture plate 80%-90%,began adding,cultured for 24 hours after the ter mination of training. Cell proliferation activity,cell viability,protein content and protein positive expression intensity of VEGF and ESM-1,cell apoptosis in early and late stage were detected by CCK-8,in vivo staining,ELISA, immunocytochemistry and flow cytometry. Results: CCK-8 assay showed that the growth of C6 glioma cells was inhibited by low,medium and high dose group;ELISA and immunocytochemistry showed that the expression of VEGF and ESM-1 was lower in the lower, middle and high dose groups, and the levels of protein expression and protein levels were decreased. The flow cytometry showed that the low dose of small radix,middle and high dose group could promote the cell apoptosis. Inverted microscope ob-servation showed that with the increase of dose,the number of cells increased gradually,and the number of dead cells increased,and all kinds of detection methods showed that the inhibition effect increased with dose and dose dependence. The difference between the two groups was statistically significant(P<0. 01). Conclusion:The growth of C6 glioma cells was significantly inhibited by Xiao Chai Hu Tang. It may play a role in inhibiting tumor growth by down regulating ESM-1 and VEGF protein level and promoting cell apoptosis.
