OBJECTIVETo investigate the blood supply of the pedicle fat grafts with the third lumbar segmental artery and its clinical effects on reoperation for lumbar disc herniation.

METHODSTwelve sides of 6 adult cadaver examples were contributed to investigate the courser of lumbar segmental vessels and the distribution of hypodermic capillary net of the dorsal branch of the third lumbar segmental artery. From January 2000 to January 2007,49 patients needed reoperation to treat lumbar disc herniation,including 26 males and 23 females with an average age of 55.6 years (ranged from 39 to 70 years). Duration between two operations ranged from 8 months to 15 years with an average of 6.9 years. Reoperative reasons included recurrent lumbar disc protrusion(30 cases)postoperative epidural scar formation (17 cases), postoperative epidural cyst formation (2 cases). Of them,9 patients underwent posterior lumbar interbody fusion at the second operation. The pedicle fat grafts with the third lumbar segmental artery were covered on the sites of the laminectomy in these patients. After negative pressure drainage tube were pulled out, 2 ml Chitsan were injected to the sites of the laminectomy and around epidural nerve root through epidural catheter. VAS score and the Oswestry Disability Index (ODI) were used to assess clinical outcomes before and after operation.

RESULTSThe courser of third lumbar segmental vessels were invariant at the lateral face of the lumbar vertebral body. The dorsal branch of the third lumbar segmental artery penetrated thoracolumbar fascia and formed rich hypodermic capillary net in the region. All patients were followed up from 5 to 8 years with an average of 5.6 years. VAS score of low back pain and leg pain decreased respectively from preoperative 7.6 +/- 1.2, 8.9 +/- 0.9 to 3.6 +/- 0.5, 3.0 +/- 0.4 at final follow-up (P < 0.01); and ODI score decreased from preoperative 44.1 +/- 6.2 to 13.9 +/- 3.6 at final follow-up (P < 0.01). According to ODI score to evaluate the clinical outcomes, 29 cases got excellent results, 11 good, 7 fair, 2 poor.

CONCLUSIONThe pedicle fat grafts with the third lumbar segmental artery and Chitsan can reduce epidural scar formation and prevent peridural fibrosis and adhesion and improve clinical effects of reoperation for lumbar disc herniation.

Objective When pathologists from hospitals at various levels encounters pathological sections diffcult to make clear diagosis, it is necessary to invite pathologists from higher hosiptals or special hospitals for pathologic consultation.In the study, we compared the pathological diagnosis of cases sent to other hospitals for pathological consultation with the original diagnostic result to analyze the differences by the evaluation on the impact of these differences on the treatment and prognosis of these patients, which would provide an effective evidence for the quality control of pathological diagnosis. Methods Cases initially diagnosed at the de-partment of Nanjing General Hospital and later sent to other hospitals for pathological consultation from 2010 to 2014 were collected. All the diagnostic results were examined by at least 3 senior pathologists to find exact diffrences between consultation results and origi-nal diagnostic results. Results Among 2055 cases, it was found that there were 1813 cases (88.2%) without diagnostic discrepan-cy, while 218 cases (10.6%) with minor diagnostic discrepancy and 24 cases (1.2%) with completely distinct diagnostic results. Conclusion The diagnostic results of the vast majority of consultation cases are in accordance with the original results, despite of di-agnostic discrepancies in some cases due to the complexity of disease. Expert consultation has reference for the pathological diagnosis of complicated cases, which also plays a potent supervisory role on the quality control of original pathologic results.

Objective In order to play the role of pathological network management system better in pathological examination, this study explore the present status of new pathology network management system, give an objective evaluation for the operation condition, reveal the effectiveness and the existing problems of this system, and provide reference for its development and improvement.Methods The software of pathological network management system was applied to the pathological specimen reception, patient information and examination status query, pathological diagnosis and technology process, as well as the paraffin block archive, statistical analysis, data recording, and so on.At last, we recorded all the information and made a classification and arrangement.Results Pathological network management system was running normally through the whole process of pathologic examination, including specimen receiving, all examinations, print of pathological applications and spontaneous print of pathological reports in ward, which really achieve one-stop services.But the system has unstable phenomenon occasionally.Conclusion Pathological network management system links each examination process closely, which can improve the work efficiency, and provide scientific basis for pathology quality control.

OBJECTIVETo evaluate the efficacy of Kirschner wires and tension-band fixation through posterolateral minimal incision for the treatment of displaced supracondylar humeral fractures in children.

METHODSFrom January 2005 to December 2010, there were 62 children (38 males and 24 females, ranging in age from 2 to 14 years, averaged 6.8 years) with Gartland type III supracondylar humeral fractures. All the injuries were caused by falling, and all the fractures were fresh injuries. The duration from injury to surgery ranged from 5 to 20 hours. All the children were treated with open reduction through a posterolateral minimal approach, Kirschnere wires and tension-band fixation were fixed with plaster at 90 degrees of elbow flexion, forearm supination, and palms facing upwards. The kirschner pins and wires were removed after fractures healing. The Flynn's criterion was used to evaluate therapeutic effects.

RESULTSThe operation time ranged from 30 to 50 min (averaged 45 min). All the patients achieved solid union. Sixty patients were followed up, and the mean follow-up time was 15 months (ranged from 6 to 24 months). At the 6th month after operation, 48 patients got an excellent result, 9 good, 3 bad (light cubitus varus with varus angle about 6 degree, without infection on function) according to Flynn's criteria. There were no complications such as procedure-related pin tract infection, iatrogenic nerve and vascular injuries and myositis ossificans.

CONCLUSIONThe Kirschner wires and tension-band fixation through posterolateral minimal incision approach can obtain clearer surgical field, simple in operation, and few wound complications. Therefore, this modified treatment is an effective and reliable method for pediatric displaced Gartland type III supracondylar humeral fractures.

This study is to offer a clinical pain-depression dyad therapy of ferulic acid, the pain-depression dyad induced by reserpine was established and the dose-effect relationship of ferulic acid on ameliorating pain-depression dyad was explored. Mice were randomly divided into control group, reserpine + vechile and reserpine + ferulic acid (5, 10, 20, 40 and 80 mg x kg(-1)) groups. The reserpine treated mice were tested with thermal hyperalgesia, mechanicial allodynia and forced swimming tests, and the SOD and NO levels of hippocampus and frontal cortex were measured. Moreover, the HPLC-ECD was used to detect the changes of central monoamines concentrations. Compared with control group, reserpine can induce a significant decrease in the nociceptive threshold and increase in the immobility time of the forced swimming test. The results suggested that reserpine significantly increased the level of nitrite in hippocampus and frontal cortex and reduced the levels of SOD, 5-HT and NE in these two brain regions. However, these indexes can be a dose-dependently reversed by ferulic acid (5, 10, 20, 40 and 80 mg x kg(-1)). Ferulic acid can reverse pain-depression dyad, especially at the dose of 80 mg x kg(-1). In addition, it can influence oxidative stress and monoamine level.
