Objective To investigate the diagnosis method of intervertebral disc low back pain and the best treatment clinical efficacy. Methods The imaging data of 132 cases with intervertebral disc low back pain diagnosed by discography for disc imaging was retrospectively analyzed from October 2001 to October 2008. Randomly divided into three groups: group A of pereutaneous laser disc decompression in 63 cases of gasification, group B extraperitoneal anterior disectomy, Cage fusion 21 cases, group C posterior fusion after disectomy arch root 48 cases of screw fixation. Observed in patients with postoperative visual analogue scale (VAS) and Oswestry disability index (ODI) score improvement. Results MRI of lumbar intervertebral disc on T_2-weightod lesions as low signal was important. VAS after treatment in three groups followed by lower values to reduce, group A was (9.7 ± 0.9) points, group B was (7.4 ± 1.2) points, group C was (6.9 ± 1.4) points. There were statistically significance between group A and group B, C (P< 0.05). ODI in order to reduce the value of reducing, group A was (19.4 ± 1.4) points, group B was (18.8 ± 2.9) points, group C was (16.5 ± 2.1) points. There were statistically significance between group A and group B, C (P< 0.05). Conclusions Discography is a reliable method to diagnose intervertebral disc low back pain. Percutaneens laser disc decompression compared with posterior or anterior disectomy and fusion combined with internal fixation has good results in improving pain and function of patients.

With the increasing incidence of pelvic fractures, the concept of damage control was applied to the treatment of severe pelvic fractures, and the principle of phased treatment and indications were put for-ward. Meanwhile, the development of damage control surgery, which improves the survival rate and reduces the disability rate of patients, brings the treatments of pelvic fractures to a new stage.

Conclusion The lateral leg flap is an optimal method for the repair of postoperative skin necrosis and nickelclad expo-sure of calcaneal fractures, which can get satisfactory clinical effects.

PurposeTo investigate the accuracy of18F-FDG PET/CT in diagnosing mediastinal and hilar lymph node metastasis of lung cancer and in guiding surgery. Materials and Methods Seventy-eight pathology-proven lung cancer patients underwent 18F-FDG PET/CT scanning and surgery. Histology was used as gold standard to evaluate the diagnosis of mediastinal and hilar lymph node metastasis.18F-FDG PET/CT was also compared to chest CT.Results The pathological examination confirmed metastasis lymph nodes in 105 out of 231 excised lymph nodes in 18 patients. No lymph node metastasis was found in mediastinum in the other 60 patients with lymph node staging of pN0. Lymph node staging was pN1 in 5 patients, pN2 in 11 patients, and pN3 in 2 patients. In all 78 cases, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of18F-FDG PET/CT were 80.9%, 94.7%, 91.0%, 85.0%, 93.1%; while 61.1%, 71.7%, 69.2%, 39.2%, 86.0% on chest CT. These were statistically different (χ2=4.325,P<0.05).Conclusion PET/CT is superior to plain chest CT examination as an accurate and efficient method in evaluating lymph nodes staging of lung cancer.

Objective To observe the multi-segmental cervical spondylotic myelopathy with simple anterior or posterior joint pre-and post-operative prognosis of spinal cord function improved and the status, explore co-operation after the clinical efficacy and complications. Methods The clinical data of 298 cases of multi-segmental cervical spondylotic myelopathy with anterior or posterior of the simple pre-and post-joint surgery from January 2001 to January 2008 were retrospectively analyzed. The clinical efficacy, titanium anterior cervical decompression and fusion surgery net implanted titanium plate fixation 121 cases, posterior open-door laminoplasty 112 cases, 65 cases of combined surgery before and after. JOA score line of spinal cord function and somatosensory evoked potential, as compared 3 groups after surgical efficacy. Results All patients were followed-up 1- 7 years, averaged (4.7±1.4) years. The anterior cervical decompression and fusion surgery titanium mesh implanted titanium plate fixation to improve the rate was 78.1%, excellent and good rate was 72.7%(88/121). Posterior open-door laminoplasty to improve the rate was 70.6%, excellent and good rate was 66.1% (74/112), there was statistically significant between them (P < 0.05). After anterior surgery, improving rate was 86.7%, excellent and good rate was 83.1% (54/65). Anterior and posterior combined surgery before and after comparison was significant (P < 0.05), regardless of near-term results, long-term effects were better than that of anterior or posterior surgery. Conclusions The spinal cord in the treatment of multi-segmental operation of cervical spondylosis after anterior surgery is obviously superior to the efficacy of anterior or posterior surgery alone. Spinal stability anterior, posterior, after a joint operation before the lower one by one.

AIM: To explore the treatment of subclinical hepatic encephalopathy(SHE) by traditional Chinese medicine. METHODS: Sixty patients with SHE were randomized into two groups: treatment group with 30 cases treated by Qingkai Granule and control group with another 30 cases treated by lactulose.They were all treated for two weeks.The evoked potentials(Eps) were measured,moreover,number connection test(NCT) and digit symbol test(DST) were conducted. RESULTS: In treatment group,the period for NCT was shorter and the DST also improved apparently;peak latency(PL) and interpeak latency(IPL) of SEP and AEPs were shorter to different degrees,with significant differences among groups. CONCLUSION: Qingkai Granule acts to effectively increase the learning,memory and space cognitive capacities in patients,and improves the nerve electrophysiology in patients.
