Objective To investigate the effect of sodium arsenite combined with cigarette smoke solution on NF-?B in rat lymphocytes. Methods Rat lymphocytes were divided into 4 groups: the arsenite treatment group, the CSS treatment group, the arsenite and CSS treatment group, and the control group. Electrophoretic mobility shift assays was used to detect levels of NF-?B DNA binding. Western blot was used to detect protein expression of I?B?. Results Levels of NF-?B DNA binding in the CSS treatment group and the arsenite treatment group were significantly increased (P

Ginseng is a typical adaptogen which has resistance to various stresses. This effect is related to the hypothalamic-pituitary-adrenal (HPA) axis. As the main active ingredients, saponin has the similar structure to steroids. The regulation characteristics of ginseng saponin on the HPA axis are narrated from the aspects of total saponin and saponin monomers in this paper after the introduction of adaptation definition and HPA axis regulation mechanisms. Pharmacological effects of ginseng saponin and the regulation effect of HPA axis are summarized finally.

Objective To investigate the impact of hepatic steatosis on the outcome of adefovir therapy in chronic hepatitis B patients with HBeAg positive. Methods The medical records of 154 patients who were diagnosed with CHB positive for hepatitis B e antigen (HBeAg) and received adefovir therapy for 24 weeks between January, 2011 and December, 2013 were analyzed retrospectively. Baseline status and virologic response, biochemical response and serology response between patient with (n = 68) and without (n = 86) steatosis who were proven by ultrasound. Both groups were given oral adefovir dipivoxil 10 mg/d for 24 weeks , recovery rate in ALT/AST, negative conversion rate of HBV DNA and HBeAg were recorded and compared. Results Recovery rate in ALT/AST in observation group was 67.7%, which is lower than control group (83.7%), and the difference is significant(P < 0.05). Negative conversion rate of HBV DNA and HBeAg in control group is 81.4%and 83.7%, which is significantly higher than observation group (whose values are 58.8% and 44.1%, P < 0.05). Conclusion Hepatic steatosis has significant impact on the outcome of adefovir treatment.

Objective To explore the psychological behavior features between different sexual children with oppositional defiant disorder(ODD).Methods The subjects were sampled from grade 1 to 5 in a primary school in Ji-nan,Shandong Province.According to the diagnosed criteria,42 pupils were diagnosed ODD,which was the study group,and 556 pupils without ODD became the control group.The pupils and their families were investigated and as-sessed by using Achenbach Child Behavior Checklist (CBCL).Results According to CBCL,there was extremely sig-nificantly higher score of depression,obsessive -compulsive,hyperactive,aggressive,interpersonal behaviors in ODD boys [(5.00 ±3.73)scores,(4.88 ±3.65)scores,(5.21 ±3.49)scores,(1 0.1 0 ±6.85)scores,(2.88 ±1 .99) scores]than those in healthy control group [(1 .65 ±2.61 )scores,(1 .91 ±2.65)scores,(2.46 ±2.63)scores, (3.95 ±4.52)scores,(1 .34 ±1 .61 )scores](t =4.31 ,3.90,4.76,4.33,4.40;P =0.000,0.000,0.001 ,0.000, 0.000).There was significantly higher score of symptoms of somatization,indiscipline,schizoid -like behaviors in ODD boys with [(2.38 ±2.50)scores,(2.63 ±2.70)scores,(3.1 7 ±2.35)scores]than those in healthy control group [(0.85 ±1 .63)scores,(0.1 3 ±1 .76)scores,(1 .51 ±1 .72)scores](t =2.94,2.85,3.37;P =0.007,0.009, 0.002).There was extremely significantly higher score of depression,communication disorder behaviors in ODD girls [(5.44 ±4.1 2)scores,(3.1 1 ±2.93)scores]than those in healthy control group with [(2.50 ±3.34)scores, (1 .36 ±2.08)scores](t =3.57,3.38;P =0.000,0.001 ).A significantly higher score of hyperactive,aggression, cruelty behaviors in ODD girls [(4.67 ±4.41 )scores,(9.33 ±7.82)scores,(1 .1 7 ±1 .79)scores]than those in healthy control group [(1 .87 ±2.38)scores,(3.1 9 ±4.08)scores,(0.24 ±0.66)scores](t =2.67,3.30,2.1 8;P =0.01 6,0.004,0.043).Conclusions According to CBCL,there were more psychological behavior problems in ODD children than healthy children.A significantly higher difference was found in different gender.

BACKGROUND:Spiral acetabular prosthesis has good stability during total hip arthroplasty.
OBJECTIVE:To observe the early therapeutic effect of Zweymüler spiral acetabular prosthesis in total hip arthroplasty for patients with developmental dysplasia of the hip.
METHODS:Totaly 38 patients (48 hips) with developmental dysplasia of the hip received total hip arthroplasty with Zweymüler spiral acetabular prosthesis from January 2011 to June 2013 were selected. The clinical effect was observed after the operation.
RESULTS AND CONCLUSION: A total of 38 patients were folowed up for 21-46 months (averagely 42.3 months). One case suffered from deep venous thrombosis. Harris scores and Charnely scores apparently increased after surgery compared with that before surgery. The mean length of the osteotomy was 2.42±0.48 cm, and the mean extended length of the affected limb was 4.58±1.15 cm. X-ray films showed that there was no disunion of the osteotomy, no subsidence and loosening of prosthesis. The position of the acetabulum was suitable. The healing time of bone graft was 3-11 months (averagely 5.3 months). The coverage of the acetabular component was 92.5%, with a good initial stability, and the excelent rate of the operation was 90%. The satisfaction rate of patients was 84%. These results indicate that the Zweymüler spiral acetabular prosthesis has the advantages of reasonable design, good initial stability, low loosening rate and high satisfaction degree. However, the number of cases of this study was relatively smal, the folow-up time was short, and only the short-term effect was evaluated. Thus, the midterm and long-term effects need to be observed by the folow-up evaluation.

Objective To evaluate the clinical results of expansive cervical laminoplasty by anterior and posterior cervical decompression in the treatment of Cervical Spondylosis Myelopathy with developmental cervical stenosis.Methods Retrospective analyze 32 patients of cervical spondylosis myelopathy treated with expansive cervical laminoplasty by anterior and posterior cervical decompression from Mar 1995 to Aug 2000 years, there were 21 males and 11 females, developmental cervical stenosis (DCS) with cervical intervertebral disc protrusion in 25 cases, with the ossification of cervical posterior longitudinal ligament (OPLL) in 7 cases. Neural functionality (JOA Scoring System), cervical axial symptoms, and pre-and post-surgery dynamic cervical spine lateral x-ray films and cervical vertebra MRI were evaluated. Results 32 cases had been followed up for an average of 24.3 months, with an average age 58.9 years (range 38-72). The average rate of improvement of the third and sixth in month postoperative,the first and third postoperative year was 58.1%,65.9%,69.1% and 68.4% respectively;the excellent and good was 71.9%,81.3%,78.1%,77.3% respectivery. Cervical axial symptoms were reduced. Instability of the cervical spine were not found and decompression was confirmed on MRI. Conclusion Expansive cervical laminoplasty by anterior and posterior cervical decompression in the treatement of cervical spondylosis myelopathy with developmental cervical stenosis have good efficacy and it is a stable operative method.

Objective: To investigate the influence of repeated infiltrating on the microstucture of In-Ceram alumina substrate. Methods:6 disks of aluminum oxide with the height of 3 mm and diameter of 12 mm were perpared and infiltrated with infiltrating glass for 0～5 times for each disk respectively.The fractured surfaces of the samples were observed by scanning elctron microscope. Results:After sintering,a net -shaped porous coping of alumina was formed. The glass infiltration resulted in a dense ceramic mass. The porous coping matrix was infiltrated with low-viscosity glass in void.3-time-infiltration resulted in the best results. Conclusion: With repeated infiltrating firing,the micro-stucture of In-Ceram alumina substrate may become a dense mass.
