BACKGROUND: Studies showed that both anterior cervical disc replacement and anterior cervical decompression and fusion can achieve good clinical result in cervical spondylosis. However, it is not conclusive about which kind of surgical method has an advantage in avoiding the adjacent segment degeneration. OBJECTIVE: To compare the effect on adjacent segment degeneration of single segment cervical disc herniation treated with anterior cervical decompression and fusion and anterior cervical disc replacement. METHODS: We col ected clinical data of 178 patients with cervical disc herniation and receiving anterior cervical disc replacement or anterior cervical decompression and fusion from January 2009 to December 2012. A retrospective analysis was performed. There were 116 cases in the anterior cervical decompression and fusion group and 62 cases in the anterior cervical disc replacement group. RESULTS AND CONCLUSION: (1) Evaluation: visual analogue scale score, Japanese Orthopaedic Association Scores and neck disability index were improved significantly in both groups during final fol ow-up compared with that pre-treatment (P < 0.05). (2) No significant difference in range of motion of operation segment, adjacent upper segment and adjacent lower segment was detected between final fol ow-up and pre-operation in the anterior cervical disc replacement group (P > 0.05). At 3 months after surgery, in the anterior cervical decompression and fusion group, surgical segment was confluent, and range of motion lost. During final fol ow-up, range of motion of adjacent upper segment and adjacent lower segment was significantly increased, and the increased range of motion in the upper segment was bigger than that of the lower segment (P < 0.05). (3) During final fol ow-up, X-ray films and MRI images revealed the number of degenerated adjacent segment was more in the anterior cervical decompression and fusion group than in the anterior cervical disc replacement group (P <0.05). The number of degenerated middle and upper segments was more than that of the lower segment in both groups (P < 0.05). (4) The findings confirmed that anterior cervical disc replacement or anterior cervical decompression and fusion for treating cervical disc herniation could effectively relieve nerve symptoms of patients. However, compared with the anterior cervical disc replacement, adjacent segment degeneration occurs more commonly after anterior cervical decompression and fusion.

A patient was treated by multiple dental implants,the implanted 6 was adjucent to impacted 8 .Immediately after implanta-tion,4 month and 3 year after implantation the distace between 8 and 6 implant central line was 4.4,3.2 and 2.5 mm,the angle between 8 long axis and 6 implant central line was 42.3°,45.5°and 50.3°.Then 8 was extracted.

Objective:To observe the changes of lung index,lung function,regulatory T cells and Foxp3,TGF-β1,Smad3,Smad7 protein expression in adjuvant arthritis(AA) rats,and to investigate the possible mechanism of Foxp3 and TGF-β/Smads signal transduction pathway in reducing lung function.Methods: 24 Wistar rats were randomly divided into normal control group and model group,12 rats in each group.The rats were injected with 0.1 ml Freunds'complete adjuvant to induce inflammation at the part of their rightback foot in model group.On the 48~(th) day post-inflammatory,the swelling degree of toe and arthritis index(AI) were observed.Lung index of the rats was calculated,and pulmonary function of the rats was detected.The percentage of regulatory T cells was determined,and pathological changes of the lungs was observed by HE staining.Foxp3,TGF-β1,Smad3,Smad7 protein expression in the lungs of the two groups of rats was examined by immunohistochemistry.Results:①Compared with those of the normal,the swelling degree of toes,AI,and the lung index were increased.The average peak expiratory flow in 1 second (FEV1/FVC),alveolitis points,TGF-β1 and Smad3 protein expression was significantly higher in the AA model group rats(P＜0.01).Forced vital capacity (FVC),25% of vital capacity of the peak expiratory flow (FEF25),50% of vital capacity of the peak expiratory flow (FEF50),75% of vital capacity of the peak expiratory flow (FEF75),maximum mid-expiratory flow (MMF),forced maximal expiratory flow (PEF),pulmonary dynamic compliance (Cldyn),the percentage of CD4~+ T cell,CD25~+ T cell,CD4~+ CD25+~ T cell,Foxp3 and Smad7 protein expression was obviously lower in the AA model group rats(P＜0.01).②FEF50,Cldyn and MMF were negative correlated with the swelling degree of toes,pulmonary coefficient and TGF-β1.FEF50,FEF75,MMF and FEV1/FVC were positiyely correlated with the arthritis index,pulmonary coefficient and Foxp3(P＜0.05 or P＜0.01).Conclusion:The decline in lung function in AA rats.Tip-induced may be sustained after the inflammation,and the development of cause inflammation,to chronic inflammatory response leading to lung injury.Simultaneously,the decline in lung function and Foxp3.Smad3,Smad7,TGF-β1 protein expression was associated.Description transcription factor Foxp3 and TGF-β1/Smads signal transducation pathway may participate in the mechanism.

Objective To review the experience of perioperative management and effect of coronary artery bypass grafting (CABG) for patients of aged＞80 years.Methods We studied 118 cases with CABG for patients of age＞80 years from January 2002 to December 2012.The other 1034 cases with CABG for patients aged 60-80 years were enrolled as control group.Logistic regression analysis was used to assess the effect of age on operative mortality and morbidity.Results The recent mortality was higher in group aged＞80 years [6.8％(8 cases) vs.3.1％(32 cases)].Through multivariate logistic regression,the patients aged＞80 years versus control were concerned about some postoperative adverse events as follows:higher mortality (OR =3.45,95 ％ CI:2.86-4.23),dialysis (OR=3.56,95％CI:3.01-4.32) and re-intubation(OR=3.87,95％CI:3.45-4.87),delayed healing of incision(OR=4.05,95 ％ CI:3.47 5.74),prolonged mechanical ventilation(OR=3.76,95 ％ CI:3.435.01),prolonged ICU stay (OR =2.98,95 ％ CI:2.67 4.12),prolonged hospital stay (OR =2.87,95％CI:2.36-3.96).Conclusions Age＞80 years is an important factor of postoperative mortality and morbidity for CABG.We need pay more attention to perioperative management.

Objective To observe the clinical curative effect of thoracic dorsal root ganglion pulse radio frequency stimulation combined with pregabalin in treatment of postherpetic neuralgia (PHN).Methods Sixty-two PHN patients were randomly divided into the single drug group and combination group (n=31).The pre-and post-treatment VAS values and pittsburgh sleep quality in-dex (PSQI),decreased dosage of tramadol after treatment,adverse reaction during treatment,and long-term therapeutic effects were observed.Results VAS values,PSQI and tramadol dosage de-creased significantly post-treatment in both groups,especially in the combination group (P < 0.05). In addition,the incidence of dizziness,somnolence and ataxia was less,but puncture pain was more in combination group (P < 0.05 ).Long-term therapeutic effects of patients in the combination group were significantly improved.Conclusion Thoracic dorsal root ganglion pulsed radio frequence com-bined with pregabalin is effective in the treatment of PHN.

Objective To review the experience of perioperative management and effect of valve replacement combined with renal dysfunction.Methods 536 cases of valve replacement.According to preoperative glomerular filtration rate(GFR),renal dysfunction was classified as normal in 322 cases,mild in 162,moderate in 40 and severe in 12.Logistic regression analysis was used to assess the effect of preoperative renal dysfunction on operative mortality and morbidity.Results Patients with a lower GFR were older and more likely to have hypertention.They also tended to have larger left ventricular end-diastolic diameter and worse left ventricular ejection factor.Operative mortality rose inversely with declining renal function,from 2％ for those with normal renal function to 17％ for patients with severe renal dysfunction.Renal dysfunction was significantly associated with a large blood transfusions,re-intubation,longer mechanical ventilation,intensive care unit stay and hospital stay.Conclusion Preoperative renal dysfunction is an important factor of postoperative mortality and morbidity for valve replacement.We must pay more attention to perioperative management.
