Objective To investigate the effect of antisense oligodeoxynudeotides(ODN)targeting nuclear factor ?B(NF-?B)on the expressions of Caspase-3 and NF-?B in glomerulosclerosis.Methods Male SD rats were divided into 3 groups:sham operation(group A,n=6),glomerulosclerosis(group B,n=6),intervention(group C,n=9).Group C was divided into 3 groups:sense ODN(group C1,n=3),non-sense ODN(group C2,n=3),antisense ODN(group C3,n=3).Glomerulosclerosis models were made for SD rats by unilateral nephrectomy and being injected with adriamycin into caudal vein.After 8 weeks,various ODN applied to corresponding group for intervention.At the end of the 9th week,kidneys were taken out from all rats for the measurement of expressions of NF-?B p65 and Caspase-3 by immunohistochemistry staining.Results After intervention,on the d7,the rats urine protein,glomerular sclerosis index(GI)and expressions of Caspase-3,NF-?B p65 in group C3 were significantly lower than those in group B,C1,C2(Pa0.05).Conclusion Antisense ODN targeting NF-?B can inhibit the activities of NF-?B,Caspase-3 in rats kidneys and retard glomerulosclerosis and glomerular intrinsic cell apoptosis.

[Objective]To investigate and compare the effects of standard gamma nail (SGN) and proximal femoral nail anti-rotation (PFNA) in the treatment of osteoporotic intertrochanteric fractures in the elderly.[Method]From May 2002 to September 2005,55 patients with intertrochanteric fractures were treated with SGN.Sixty-eight patients were treated with PFNA from November 2005 to June 2008.The effects of the two implants about perioperative complications,bone healing and the function of the operated hip joint were compared.[Result]No statistically significant difference was found between the two groups in blood loss,blood transfusion,infection,deep venous thrombosis and hospital stay.One patient developed femoral head avascular necrosis postoperatively in Gamma nail group.The incidence of postoperative hip pain in Gamma nail group was higher than that in the PFNA group,but there was no significant difference in the Harris score.[Conclusion]Gamma nail and PFNA nail are reliable methods to treat geriatric intertrochanteric fractures,with advantages of minimal iatrogenic injury,stable fixation and few complications.

In this research, mononuclear cells from cord blood were modified with 3mg/ml, 6mg/ml and 12mg/ml methoxy polyethylene glycol (mPEG) respectively. The cell surface antigens and the ability of CFU GM proliferation of mPEG modified cord blood lymphocytes were analyzed. Flow cytometric analysis demonstrated that mPEG modified lymphocytes attenuated CD3, CD4 and CD8 antibodies binding to antigens on lymphocyte surface ( P

Objective To observe the clinical efficacy of triple needling at myofascial trigger points plus warm needling in treating periarthritis of shoulder. Method Eighty patients with periarthritis of shoulder were randomized into a treatment group of 44 cases and a control group of 40 cases. The treatment group was intervened by triple needling at myofascial trigger points plus warm needling, while the control group was by warm needling alone. The two groups were treated once a day, 10 times as a treatment course. The Pain Rating Index (PRI), Visual Analogue Scale (VAS), Present Pain Intensity (PPI), and motion of shoulder joint were observed before the treatment and after 2 treatment courses, and the clinical efficacies were compared between the two groups.Result In the treatment group, the PRI, VAS, and PPI scores respectively after 1 and 2 treatment courses were significantly different from those before the treatment (P<0.05,P<0.01). In the control group, the scores after 2 treatment courses were significantly different from those before the treatment (P<0.05). After 2 treatment courses, the scores in the treatment group were significantly different from those in the control group (P<0.01). In both groups, the motions of shoulder joint respectively after 1 and 2 treatment courses were significantly changed compared with those before the treatment (P<0.01). The motions of shoulder joint in the treatment group were significantly different from those in the control group respectively after 1 and 2 treatment courses (P<0.05,P<0.01). The recovery plus markedly-effective rate and total effective rate were respectively 70.5% and 95.5% in the treatment group, versus 52.5% and 90.0% in the control group, and the between-group differences were statistically significant (P<0.01,P<0.05).Conclusion Triple needling at myofascial trigger points plus warm needling is an effective approach in treating periarthritis of shoulder.

Objective To investigate the efficacy of the enhancement treatment on osteoporotic vertebral compression fracture and its complications in the elderly.Methods From September 2007 to February 2012,183 patients with osteoporotic vertebral compression fracture underwent percutaneous kyphoplasty (PKP) or percutaneous vertebroplasty (PVP) in our department.157 of them were completely followed up (PKP group,n=96; PVP group,n=61) and totally 182 vertebral bodies were fractured (PKP group,n=107; PVP group,n=75).Visual analogue scale (VAS) score and Oswestry disability index (ODI) score were evaluated before and 3 days and 3 months after the surgery.Plain film radiography was taken to evaluate the vertebral body height.ODI score was evaluated at the end of the follow-up.The leakage of polymethylmethacrylate (PMMA) during the operation and the refracture were recorded.Results The mean height of the vertebral body before operation had no difference between PVP and PKP group [(1.31±0.18) cm vs.(1.32±0.16) cm,t =0.72,P＞0.05].After the operation,the mean height of the vertebral body was lower in PVP group than in PKP group [(1.50±0.20) cm vs.(1.66±0.17) cm,t=2.28,P＜0.05].The mean amount of the PMMA injected into the vertebral bodies was less in PVP group than in PKP group [(2.93±0.34) ml vs.(3.34±0.49) ml,t=2.39,P＜0.05].In the PVP group,the VAS scores were (7.5±0.79),(3.0±0.6) and (1.9±0.9) before,3 days and 3 months after operation respectively,and there was a significant difference in VAS score before versus 3 days after operation (t =15.59,P＜0.05).In thePKPgroup,the VAS scores were (7.3±1.0),(3.0±0.8) and (2.2± 0.9)before,3 days and 3 months after operation respectively,and there was a significant difference in VAS score before versus 3 days after operation (t=10.69,P＜0.05).In the PVP group,the ODI scores were (78.9±7.3),(30.0±3.7) and (25.5±3.5) before and 3 months after operation and at the end of follow-up respectively,and there were significant differences in ODI score before operation versus 3 months after operation (t=20.83,P＜0.01) and 3 months after operation versus at the end of follow-up (t=4.03,P＜0.05).In the PKP group,the ODI scores were (78.8±6.8),(29.8±4.43) and (23.8 ± 2.7) before operation,3 months after operation and at the end of follow-up respectively,and there were significant differences in ODI score before operation versus 3 months after operation (t=21.52,P＜0.01) and 3 months after operation versus at the end of follow-up (t=3.14,P＜0.05).There were no significant differences in VAS and ODI scores between the two groups before versus after operation (t=0.34,P＞0.05).The incidence of refracture was 8.2％ in PVP group and 9.4％ in PKP group,which had no statistical difference between the two groups(x2 =0.06,P＞0.05).All the leakage was asymptomatic.The incidence of PMMA leakage was 20.0％ (15 cases) in PVP group and 9.3％ (10 cases) in PKP group,which had a statistical difference between the two groups (x2 =4.22,P ＜ 0.05).Conclusions Enhancement treatment for osteoporotic vertebral compression fracture can quickly relieve the pain and improve the quality of life.PKP and PVP show no differences in the effect of analgesia and the improvement of life quality,but PKP has the advantages in recovering vertebral height and reducing PMMA leakage.

Objective To investigate the treatment effect of the proximal humeral internal locking system (PHIL()S) on the elderly patients with displaced proximal humeral fractures.MethodsFrom Feb 2004 to Mar 2007, 36 patients (mean age: 72.2 years) with proximal humeral fractures were treated with PHILOS plate fixation which included 14 cases with 2-part, 17 cases with three-part and 5 cases with four-part fractures according to Neer classification.Operation time,intraoperative blood loss, blood transfusion, perioperative complications and function evaluation of the operated shoulder joint were calculated with 14.5 months follow-up at average.Results The average operation time and blood loss were (61.5± 11.6) min and ( 165.2±91.2) ml, respectively. 1 case with accidents of blood vessel and 1 case with pneumonia were found without neurovascular injuries. All fractures were radiographically healed in an average of 3-5 months.No necrosis of humeral head appeared and 30 (83.3％) cases were excellent or good according to Neer scoring system. Two part fracture and early operation ( within 3 days after operation) might improve the postoperative function of shoulder joint, but the patient's age, gender and ASA score were not statistically with Neer score.Conclusions PHILOS plate fixation is a suitable procedure for displaced proximal humeral fractures via stable fixation and early rehabilitation, especially for elderly patients combined with osteoporosis.

Objective: To evaluate the eruption of mandible third molar in orthodontic patients with non-extraction or extraction of the lower premolars. Methods: We selected 3 group of the orthodontic patients. One group consisted of 23 subjects (12 males, 11 females, average age 13.5 years) with non-extraction. One group consisted of 23 subjects (12 males, 11 females, average age 13 years) with lower first premolar extraction. One group consisted of 21 subjects (11 males, 10 females, average age 14.07 years) with lower second premolar extraction. The panoramic radiography was taken. The lower third molar angulation and eruption space were measured before and after the orthodontic treatment. The comparison of treatment changes in 3 groups were performed by means of a paired-sample t test using SPSS 17.0 software package. Results: The RS, LS, Rratio and Lratio increased significantly after treatment in patients with lower first premolar extraction(P<0.01). The RM3 and LM3 increased(P<0.05) and RS, LS, Rratio and Lratio increased significantly(P<0.01) after treatment in patients with lower second premolar extraction(P<0.05). Conclusion: The mandibular third molars show improvement in eruption space and inclination in the orthodontic patients with lower premolar extraction.
