Chinese Journal of Trauma 1993;0(06):-
Objective To investigate the effect of nuclear factor-?B (NF-?B), NF-?B-inducing kinase (NIK) and I-?B in basic fibroblast growth factor (bFGF) promoting gene expression and signal transduction of tenocyte NF-?B. Methods Tenocytes isolated from rabbits were divided into 3 groups with 8 dishes: no bFGF (Group A), 2 ng/ml bFGF (Group B) and 10 ng/ml bFGF (Group C). Cells in all dishes were cultured for 5 days. The effect of bFGF on tenocytes proliferation was examined by means of growth curve analysis. The mRNA was isolated after 5 days and the gene expressions of NIK,IKK? and IKK? induced by NF-?B investigated by reverse transcription-polymerase chain reaction (RT-PCR). Results The growth curve moved forward with the dosage increase of bFGF. Gene expressions of NF-?B,NIK, I?B kinase (IKK)? and IKK? were 0.4? 0.2 , 0.4 ? 0.1 , 0.3 ?0.1 and 0.2?0.1 respectively in the Group B and 1.8?0.5,1.0?0.3, 0.8 ? 0.2 and 1.5 ? 0.4 in the Group C. Gene expressions were all up-regulated in the Groups B and C posterior to adding of bFGF. Conclusions bFGF stimulates tenocyte proliferation and up-regulates gene expression of NF-?B,NIK,IKK? and IKK?, as indicates that the signal transduction of promoting tenocyte proliferation by bFGF may be through NF-?B pathway.

BACKGROUND:For the treatment of Achil es tendon rupture, peripheral ankle autologous tendon displacement is the traditional method in clinic, while the source of autologous tendon is limited, has damage to the donor site and has to pay with the normal power and stable structure. Al ogenic tendon has the advantages of rich sources, easy to obtain, no damage to the normal structure of the host, and can maintain its original biological structure. OBJECTIVE:To evaluate the clinical effect of tendon al ograft transplantation on the repair of Achil es tendon rupture. METHODS:Thirty cases of acute and old Achil es tendon rupture and four cases of chronic rupture with 2-5 cm deficiency were treated from August 2008 to June 2011. The cases were treated with tendon al ograft transplantation, and short leg cast was used to fix the limb after transplantation. Functional exercises were commenced at 4 weeks after cast removal. The clinical treatment results were evaluated by Arner-lindholm criteria. RESULTS AND CONCLUSION:The mean hospital stay was about 12.5 days. Twenty-five cases were fol owed-up for 1-3 years after transplantation and no rupture recurred. According to Arner-lindholm criteria, excel ent was in 25 cases, good in 3 cases, fair in 2 cases, and the excel ent and good rate was 92%. Ankle joint function was recovered to the normal level. Three cases had adhesion between Achil es tendon and adjacent tissue that had impact on the ankle dorsiflexion, and there was no significance decrease in foot pedal force. Two cases had rejection that healed after symptomatic treatment. One case had less flap margin necrosis and incision infection that healed after dressing and adjacent flap coverage. Incisions of al patients were healed at discharge. The results show that tendon al ograft transplantation has satisfactory effect for reaping the Achil es tendon rupture which is a recommended treatment option. But the long-term effect needs further observation.

ObjecfiveTo compare the sensitivity of diffusion weighted imaging(DWI)with dynamic contrast enhanced(DeE)MRI for the detection of small breast caJlcers and to evaluate the clinical value of DWI.MethodsForty-eight patients with benign(n=25)and malignant(n=45)small breast lesions(≤2 cm)proved by pathology underwent DWI and DCE MRI.The DCE MRI was performed using FLASH sequence and the time-signal intensity chive was drawn.The DWl was performed using GRAPPAEPI sequence with different b values(800,1000 s/mm2) and the ADC values of lesions were measured.The sensitivity and specificity of DWI for the detection of small breast cancers were compared with DCE MRI. ResultsForty of 45 small breast cancers and 19 of 25 small benign breast lesions were corrlectly diagnosed using DCE MRI.The sensitivity and positive predictive value of TIC were 88.9%(40/45)and 87.0%(40/46).With b values of 800 s/mm2 and 1000 s/mm2,the avemge ADC values of small breast cancers were(1.153±0.192)× 10-3 and(1.079±0.186)× 10-3 mm2/s,while those of benign ones were (1.473±0.252)×10-3 and(1.419±0.255)×10-3 mm2/s,respeetively. There was no significant difference for the ADC values with different b values in the same group(P>0.05),while there was a signiticant difference between the malignant and the benign lesions(P<0.05)Thirty-nine of 45 small breast cancers and 19 of 25 small benign breast lesions were correctly diagnosed using DWI with b value of 1000see/mm2.Both the sensitivity and positive predictive value of diagnosis were 86.7%(39/45).The abilities of DWI and DCE MRI for the diagnosis of small breast cancers werle the same. The sensitivity(93.3%)and positive predictive value(91.3%)were improved with the combination of DCE MRI and DWI. Conclusion DWI has a high sensitivity for the detection of small breast cancers,the ADC value can provide valuable information in the differential diagnosis.

To explore the protective effect of adenovirus mediated IGF-Ⅰgene(Ad-IGF-Ⅰ)transfer on non-obese diabetic(NOD)mice. The results showed that the incidence of diabetes and degree of insulitis were significantly reduced in mice receiving Ad-IGF- Ⅰ . Treatment with Ad-IGF- Ⅰ significantly decreased apoptosis rate,expression of Fas and caspase-3, and increased expression of Bcl-xl. This study indicates the potential of IGF- Ⅰ gene therapy in protecting NOD mice from insulitis and apoptosis.

Objective To analyze the levels of T helper(Th)17-related cytokines interleukin(IL)-17,IL-22,IL-23 and IL-27 in plasma of patients with systemic lupus erythematosus(SLE).Methods Plasma IL-17,IL-22,IL-23 and IL-27 levels were measured by enzyme-linked immunosorbent assay in 45SLE patients and 32 healthy controls and their associations with each other,disease activity and clinical features were evaluated.Results Plasma levels of IL-17 and IL-23 were significantly higher in SLE patients than in controls[77.8(25.4~487.6)pg/ml vs 36.4(15.7~338.2)pg/ml;14.7(<7.8~247.5) pg/ml vs <7.8(<7.8~81.7)pg/ml.both P<0.01].with no difference between active and inactive disease.In contrast,IL-22 levels were markedly decreased in SLE patients compared with the controls[77.4(<15.6~559.7)pg/ml vs 378.8(21.8~1154.2)pg/ml,P<0.01]and were lower in active disease than in inactive disease(P<0.01).IL-27 levels tended to be higher in SLE patients compared with controls,but the difference was not significant (P>0.05).A strong and positive correlation was found between IL-17 and IL-23 levels(P<0.01)in SLE patients.IL-22 levels were negatively correlated with SLEDAI score,erythrocyte sedimentation rate and antidsDNA antibody titers(all P<0.01),and positively correlated with C3 levels (P<0.05).Each cytokine levels were not related to specific manifestations and treatments.Conclusion Th17 cytokine response in peripheral blood of patients with SLE is abnormal.and IL-17 and IL-22 appear to play different roles in SLE pathophysiology.IL-23/IL-27 imbalance may contribute to the development of Th17-mediated inflammation in SLE.
