Injury of peripheral nerve is a so common complication in trauma, that it is important to improve regeneration to recover the function of peripheral nerve. This paper has reviewed the pathology after injury of peripheral nerve, condition of successful regeneration of peripheral nerve, experiment and clinical study of electrical stimulation promoting regeneration of peripheral nerve and the possible mechanism. The effect of electrical stimulation on promoting regeneration of peripheral nerve has been gradually accredited. However, further study is still needed to discover the many unknown field.

Objective To investigate the expression of CD158b in NK cells after allogeneic kidney transplantation.Methods In 62 patients with allogeneic kidney transplantation, blood samples were collected on the day before operation, first, 7th day after operation, the moment the graft (reco)-(vered) and the acute rejection occurred. The expression of CD158b was detected in peripheral blood NK cells. The ratio of CD3~-CD16/56~+CD158b~+ was measured.Results There were 38 patients without acute rejection during the whole transplantation period. The ratio of CD3~-CD16/56~+ cells and CD3~-CD16/56~+CD158b~+ cells were stable before and after the transplantation. Twenty-four patients experienced acute rejection post-transplantation. The ratio of CD3~-CD16/56~+ cells was increased significantly after acute rejection, the ratio of CD3~-CD16/56~+CD158b~+ cells decreased significantly, and the percentage of CD3~-CD16/56~+CD158b~+ cells of total NK cells decreased significantly.Conclusion There are not too much factors interfering with the expression of CD158b in NK cells, and the ratio of CD3~-CD16/56~+CD158b~+ cells had already decreased significantly before the clinical diagnosis of (acute) rejection. Monitoring of CD158b in NK cells is more accurate and sensitive for the evaluation of immune state.

This study was designed to investigate the application of multi-slice spiral CT(MSCT)and airway reconstruction in the patients with obstructive sleep apnea syndrome(OSAS).Using GE Lightspeed16 scanner,MSCT and airway three-dimensional reconstruction were performed on 33 patients with OSAS,who were admitted in the Chinese PLA General Hospital between 2004 and 2005.The sagittal diameter,coronal diameter and the section area of upper airway were measured.The results showed that the narrowest place of the airway in OSAS patients was the posterior soft palate region,in which the sagittal diameter,coronal diameter and the section area were 8.96 mm,16.64 mm and 164.62 mm2 respectively,and then was palatine uvula region.With MSCT scanning and post-processing,a precise measurement of airway can be gotten,and stenosis locus and scope are easy to be localized,which will provide reliable evidences for treatment scheme and surgical mode.

To compare the postobturation pain and therapeutic effects in root canal therapy between two root canal filling materials: AH Plus and zinc oxide eugonol. Four hundred and twenty four teeth requiring root canal therapy were randomly divided into 2 groups: AH Plus ( trial group ) or zinc oxide eugonol ( control group) were used in treatment respectively. The pain intensity after treatment was evaluated by visual analogue scale. The therapeutic effects were evaluated by follow-up for 6 and 12 months. The pain intensity of trial group was significantly lower than that of the control group in 3rd and 7th day[8. 5% ( 18/212) vs. 15.6% (33/212),5.2% (11/212) vs. 14.6% (31/212),both P ＜0.05]. There were no significant differences in effictive rate between two groups after follow-up for 6 and 12 months[92. 5% ( 196/212) vs. 89. 6% ( 190/212 ) ,91.5% ( 194/212 ) vs. 88.7% ( 188/212 ), both P ＞ 0. 05]. AH Plus root canal filling paste used in root canal therapy can significantly decrease postoperative pain.

Objective:To investigate and analyze the current status of multimodality therapy for resectable gastric cancer, aiming to provide reference for optimizing the multimodality treatment strategy for gastric cancer.Methods:Clinical data of patients diagnosed with gastric adenocarcinoma undergoing radical gastrectomy in the Second Affiliated Hospital of Soochow University were retrospectively analyzed. Clinical characteristics, preoperative medical comorbidities, pathological features, surgical and perioperative status and clinical efficacy were recorded. The gap between the diagnosis and treatment procedures and the standard guidelines was analyzed. The changes in the multimodality treatment patterns for gastric cancer were understood.Results:A total of 265 patients were included in this study. All patients were divided into two cohorts: early[2008] and late[2013] cohorts. In the early cohort, 127 patients were assigned, and 138 cases in the late cohort. In the early cohort, 67 patients (52.8%) underwent D 2 lymph node dissection, significantly less than 83 patients (60.1%) in the late cohort ( P<0.01). In the early and late cohorts, the proportion of patients with the number of lymph node dissection of ≥15 was 5.5% and 52.8%( P<0.01). The median number of lymph node dissection was increased from 6 to 16. The proportion of patients receiving neoadjuvant chemotherapy in the early and late cohorts was 2.4% and 3.6%( P=0.55). In the early cohort, the proportion of patients treated with postoperative chemotherapy and postoperative adjuvant chemoradiotherapy was 62.6% and 2.4%, significantly higher compared with 58.0% and 8.0% in the late cohort ( P=0.04). In addition, the proportion of patients receiving postoperative chemotherapy in the early cohort was 62.2%( n=79) and 58.0%( n=80) in the late cohort ( P=0.48). Conclusions:Although the level of radical gastrectomy has been continuously improved and standardized in China, which still lags behind the standard D 2 radical gastrectomy in Japan and South Korea. Adjuvant therapies including postoperative adjuvant radiotherapy can bring clinical benefits. However, the proportion of patients receiving adjuvant therapy is still low, and the multimodality therapy of gastric cancer should be widely applied.

ObjectiveTo analyze and summarize the feasibility and characteristics of the posterior spinal canal reduction and fixation in treating mid-upper thoracic spine facture.MethodsA retrospective study was made on 17 patients with mid-upper thoracic spine facture to record the complication, compare the functions of the patients with complete and incomplete spinal cord injuries before and after surgery and examine the iatrogenic injury in patients without spinal cord injuries.ResultsNo complication happened after surgery.Incomplete injury was found in six patients, whose ASIA scales were found to be increased for 1-3 levels during the follow-up.While the complete injury was found in eight patients,whose ASIA scale remained unchanged during the follow-up.The sensory scores of both the incomplete injury group and complete injury group were processed with variance analysis and the results showed a significant difference between pre-operation and post-operation (F = 476.47, P = 0.000).The mean value between complete injury group and incomplete group was with high statistical difference (F = 31.46, P =0.000).The variance analysis of the motor scores showed a significant difference between before and after operation (F=46.75, P =0.000) and the mean value between complete and incomplete injury groups was with statistical difference (F = 158.59, P = 0.000).There were three patients with normal spinal cord function, with no decrease of ASIA scale or no change of the sensory and motor scores.ConclusionsFor patients with mid-upper thoracic spine fracture, posterior spinal surgery is conducive to the recovery of spinal function, for it can safely and effectively avoid worsening the thoracic and other combined injuries and release spinal pressure including the pressure in front part of the spinal cannal.

Objective To investigate the effect of aurora kinase inhibitor VX-680 on cell apoptosis and Bcl-2 expressions in human bladder cancer T24 cells. Methods T24 cells were cultured and treated with VX-680 at various concentrations and time points in vitro. VX-680-induced apoptosis of T24 cells was calculated by flow cytometry. The morphological change of treated cells was observed by microscopy;Bcl-2 mRNA and protein expression in T24 cells was detected by RT-PCR and Western blot assay , respectively. Results The apoptosis rate of VX-680-induced T24 cells increased in a dose-and time-dependent manner. The increase of apoptosis rate and decrease of Bcl-2 mRNA and protein expression in VX-680-induced T24 cells were in a dose-dependent manner. Conclusion VX-680 can significantly induce the apoptosis of T24 cells by down-regulating Bcl-2expression in a dose-dependent manner.

Objective To analyze the rationality of 16 or more multi-slice helical CT (MSCT) utilization for solitary pulmonary nodule (SPN) (<3 cm). Methods One hundred and fifty consultant cases with SPN from 133 different hospitals, examined with 16 or more MSCT, were selected in this study. The reconstructed slice thickness of routine CT scan, thin slice reconstruction thickness, 2D or 3D reconstruction, window wide and level setting, contrast enhancement effect were recorded from consultant films. Thoracic CT scan criteria for SPN were proposed according to the scan guidelines at Stanford University and PubMed articles. The rationality of 16 or more MSCT utilization in other hospitals for SPN was analyzed by two radiologists compared with scan criteria. The diagnostic accuracy in other hospitals was evaluated according to the pathologic and treatment results in our hospital. Results Sixteen-MSCT was performed in 92 cases, 64-MSCT in 54 cases and 40-MSCT in 4 cases. In routine thoracic CT scan, 9--10 mm reconstructed slice thickness was selected in 59 cases, 7--8 mm thickness in 12 cases and 5 mmthickness in 79 cases. Consecutive thin slice thickness (<3 mm) was used for SPN only in 46 cases. OnlyMPR and VR were filmed in 9 cases without thin slice reconstructed axial images. :53 cases (35.3%) were rescanned in our hospital due to the unsatisfied image quality. Of 150 cases, 78 cases had pathologic or treatment results in our hospital and 22 cases (14.7%) were proved to be misdiagnosed in other hospitals, and only 2 cases were misdiagnosed in our hospital. Conclusion There are many irrationalities of 16 or more MSCT utilization in our country which influence the diagnostic accuracy of SPN, Unified thoracic CT scan criteria in our country are needed.
