ABSTRACT

OBJECTIVE To study the correlation of novel organic cation transporter 2 (OCTN2) with the chemosensitivity of prostate cancer cells to oxaliplatin. METHODS Tumor samples of patients receiving radical prostatectomy were collected, and OCTN2 protein was detected with immunohistochemistry; the primary cells of the specimen were cultivated to obtain prostate cancer cell line. Inductively coupled plasma mass spectrometry was used to detect the uptake of low concentration (0.1 μmol/L) of oxaliplatin by cancer cells. Real-time PCR and Western blot were used to detect the mRNA and protein expressions of OCTN2 in cancer cells; the prostate cancer cells with the highest and lowest expression of OCTN2 protein were selected, and IC50 of oxaliplatin to prostate cancer cells was analyzed by ATP-TCA method. The inhibitory rate of plasma peak concentration of oxaliplatin (50 μmol/L) to prostate cancer cells was detected by MTT assay. Spearman method was used to analyze the relationship of the uptake of oxaliplatin by prostate cancer cells with inhibitory rate of oxaliplatin to prostate cancer cells and 505916443@qq.com mRNA expressions of OCTN2. RESULTS OCTN2 was located on the membrane of cancer cells, and the uptake of zjdtztougao@163.com oxaliplatin by cancer cells was 0.283±0.264 (n=12)mRNA and protein expression of OCTN2 varied significantly among different cancer cells. The sensitivity of cancer cells with high expression of OCTN2 to oxaliplatin (IC50 of 4.61 μmol/L) was higher than that of cancer cells with lower expression of OCTN2 (IC50 of 26.23 μmol/L). The inhibitory rate of oxaliplatin to cancer cells was (25.4±10.8)% (n=12). There was a correlation between the uptake of oxaliplatin by prostate cancer cells and the inhibition rate of oxaliplatin to prostate cancer cells and mRNA expression of OCTN2 (P<0.05). CONCLUSIONS High-expressed OCTN2 may promote the uptake of oxaliplatin by prostate cancer cells, and its expression can serve as a reference for predicting the sensitivity of prostate cancer cells to oxaliplatin chemotherapy.

ABSTRACT

Objective To evaluate the efficacy and adverse reactions of preoperative intensity-modulated radiotherapy (IMRT) combined with mFOLFOX6 chemotherapy regimen for locally advanced rectal cancer (LARC). Methods A total of 86 patients with LARC who received preoperative IMRT combined with chemotherapy in Shanxi Provincial Cancer Hospital from June 2010 to December 2012 were enrolled. The patients were randomly divided into 2 groups according to the random number table method. Forty-six patients were treated with mFOLFOX6 regimen (mFOLFOX6 group) and 40 patients were treated with fluorouracil (5-Fu) single drug injection (5-Fu group). The total dose of IMRT target region was 45-54 Gy, 25 times in total. Short-term efficacy, adverse reactions, survival and metastasis were evaluated respectively. χ 2test or Fisher test were used to compare the count variable. Kaplan-Meier method was used to calculate the survival rates and Log-rank was used to detect. Results The total follow-up rate was 97.67 % (84/86). There were no statistical differences in the rate of resection (93.5 % vs. 80.0 %), pathological complete remission (pCR) rate (6.5 % vs. 0) and 3-year overall survival (OS) rate (87.0 % vs. 70.0 %) in the mFOLFOX6 group and 5-Fu group respectively (all P > 0.05). Down-staging rate, 3-year disease free survival (DFS) rate and distant metastasis free survival (DMFS) rate in the mFOLFOX6 group were significantly higher than those in 5-Fu group (58.7 % vs. 32.5 %, 79.1 % vs. 50.0 %, 89.1 % vs. 72.5 %, all P <0.05). Conclusions Preoperative IMRT combined with mFOLFOX6 regimen can decrease the preoperative staging of LARC patients, improve 3-year DFS rate and DMFS rate. The adverse reactions may increase, but it is tolerant.

ABSTRACT

Objective To observe and compare in vivo segmental lumbar motion between symptomatic L4 isthmic spondy?lolisthesis (IS) patients and L4 degenerative spondylolisthesis (DS) patients during functional weight?bearing activities. Methods Fifteen symptomatic L4 IS patients and fifteen symptomatic L4 DS patients were recruited. Fifteen asymptomatic volunteers were en?rolled as the control group. The L4,5 vertebral segment motion of each subject was reconstructed using three?dimensional computed tomography and a solid modeling software. In vivo, lumbar vertebral motion during functional postures (flexion?extension, left?right twisting and left?right bending) was observed using a dual fluoroscopic imaging technique. The spinal function unit was divided in?to anterior and posterior segments by the isthmic cleft. Local coordinate systems were established at the vertebral body, to obtain the 6 degree?of?freedom (DOF) intervertebral range of motion (ROM) at L4,5 and the ROM between the anterior and the posterior segments of L4 IS. Results The motion of IS at L4,5 was found to be increased. The migrations along both sagittal and vertical axis were significantly larger than control group (P<0.05). During left?right twisting, the migration along sagittal axis was significantly larger than control group (P<0.05);the rotation along vertical axis was significantly larger than DS and control group (P<0.05). During left?right bending, the migration along frontal axis was significantly larger than DS and control group ( P<0.05). The inter?vertebral ROM at L4,5 showed no significant difference between DS and control group. The migration between anterior and posteri?or segments of IS L4 was larger in standing than supine (P<0.05). The relative migration along sagittal axis between anterior and posterior segments of IS L4 was significantly larger in flexion than standing (P<0.05). Conclusion A spondylolytic defect does lead to detectable instability or hypermobility in the lumbar spine compared with degenerative spondylolisthesis and normal group. From supine to standing posture, migration at isthmic cleft along sagittal and coronal axis are identified in IS spondylolithesis.

ABSTRACT

Objective:To explore the relationship between periodontitis and coronary heart disease (CHD)by meas-uring changes of serum inflammatory cytokine levels.Methods:A total of 197 patients from our hospital were en-rolled,including CHD + periodontitis group (123 cases),pure CHD group (CHD group,39 cases)and pure peri-odontitis group (periodontitis group,35 cases).Another 45 healthy subjects were enrolled as healthy control group. Concentrations of tumor necrosis factor-α(TNF-α),interleukin-6 (IL-6),serum amyloid-a (SAA),high sensitive C reactive protein (hsCRP)and plasma fibrinogen (Fg)were measured in all groups,and levels of above inflammatory cytokines were compared among four groups.Results:Compared with healthy control group,there were significant rise in levels of above inflammatory cytokines in CHD + periodontitis group (P0.05 all).Conclusion:Serum inflammatory cytokine levels significant rise in palients with periodontitis,it is related with coronary heart disease.

ABSTRACT

BACKGROUND:Gait deviations are the important diagnosis criteria and surgical indications of cervical myelopathy. Conventional three-dimensional gait laboratory failed to apply in clinics due to complex operations and time consuming. In recent years, a portable gait analyzer based on the micro-sensors is emerging and developing, it has been verified by clinical practice, al owing gait analysis in the ward. OBJECTIVE:To quantitatively analyze gait characteristics of patients with cervical spondylotic myelopathy (CSM) by a portable gait analyzer. METHODS:From March 2013 to November 2013, 15 CSM patients and 30 healthy subjects were enrol ed in the study. The involved patients were accompanied by gait abnormalities. A portable gait analyzer was used for gait analysis. Subjects walked on a 30-meter corridor back and forth for 120 meters. Total y 12 gait parameters were involved in this study, including seven common parameters (single limb support, double limb support, gait cycle, speed, cadence, step length and stride length) and five new parameters (pul ing acceleration, swing power, ground impact, foot fal , and pre-swing angle). Three patients underwent cervical decompression surgery. The gait characteristics were re-evaluated one week later, carrying neck support. RESULTS AND CONCLUSION:The double limb support and gait cycle duration of CSM group were significantly longer than control group (P0.05). after cervical decompression surgery, the mean remission rate of Japanese Orthopedics Association scores was 32.5%and lower limb acceleration was improved obviously in the graph one week after surgery. Varying degree of correlation was seen between Japanese Orthopedics Association scores and the detected 12 gait parameters in CSM patients. The portable gait analyzer can effective measure the pathological gait deviation in CSM patients with abnormal gaits, and assists to evaluate the lower limb functions.

ABSTRACT

Objective To employ intraoperative discography to determine the injured intervertebral disc segments that can not be identified on the preoperative MRI in patients with cervical spinal cord injury without fracture and dislocation for confirming the responsible segments needing surgical decompression and fusion.Methods The study involved 85 patients with cervical spinal cord injury without fracture and dislocation treated from January 2007 to December 2011,among which sixteen patients had not been identified with the responsible segments by preoperative MRI.The average preoperative Japanese Orthopedic Association (JOA) score was (9.1 ± 1.8) points.There was no obvious fracture or dislocation of the cervical spine on preoperative X-ray film,CT and MRI,but all patients displayed high intense signal in cervical spinal cord on MRI T2 weighted imaging.Besides,MRI revealed hemorrhagic swelling of anterior cervical soft tissue in nine patients and cervical intervertebral disk hernia in all patients.Annulus fibrosus rupture of cervical intervertebral disc with contrast leakage in intraoperative discography of suspected injury segments in all patients under direction of C-arm X-ray machine was set as the injury criterion.The patients with pure ruptured discs received cervical discectomy,interbody fusion and titanium plate fixation.The patients associated with multilevel cervical intervertebral disc hernia or ossification of posterior longitudinal ligament underwent anterior cervical corpectomy,bone graft with titanium cageand titanium plate fixation of ruptured discs.Results Nineteen injured discs were identified eventually by discography,including 2 discs at C3/4,4 at C4/5,8 at C5/6 and 5 at C6/7.Moreover,anterior annulus fibrosus rupture with intact anterior longitudinal ligament was found in 11 patients.The follow-up lasted for (24.4 ± 10.0) months.JOA scores were (13.3 ± 1.5) points and (14.5 ± 1.6) points at two weeks and three months after operation,and (15.1 ± 1.5) points at the last follow-up,indicating a relevant improvement rate of 53%,68% and 76% respectively.Mean operation time was 110 minutes and blood loss was 120 ml.Three patients had pain on shoulder and back and one patient had hoarse voice,but all the patients were relieved in two weeks after conservative treatments.No serious complications,such as deep infection,deterioration of neurological dysfunction,vertebral artery injury or internal fixation failure were noticed intra-or post-operatively.Conclusion For the intradiscal rupture that is hard to be determined by the conventional imaging methods,intraoperative discography can be used as an auxiliary method of imaging diagnosis in early surgical determination of responsible segments for cervical spinal cord injury without fracture and dislocation.

ABSTRACT

Objective To evaluate the effect of en bloc open-door laminectomy and pedicle screw fixation for extremely severe cervical ossification of posterior longitudinal ligament (OPLL).Methods From January 2007 to December 2011,16 cases of serious cervical OPLL were treated,in which there were 13 males and 3 females,aged from 45 to 74 years (average,56.5 years).Spinal cord functional deterioration was related to minor activities of the neck,such as sneeze,cough or hyperextension of the neck,in 15 cases.One case suffered from aggravating neurological symptoms without a definite precipitating factor.The average preoperative Japanese Orthopaedic Score (JOA) was 7.1 ±1.8.Preoperative CT scans displayed the average stenotic rate (thickness of OPLL/sagittal diameter of the spinal canal) was 83.7%.All the patients received en bloc laminectomy and pedicle screw fixation of the cervical spine.Results All the patients were followed up for 3 months to 4 years (average,24.4±10 months).The JOA scores at 2 weeks,3 months,and the last follow-up postoperatively were 13.2±1.7,13.5 ±1.6 and 14.1 ±1.5,respectively; the improvement rates were 61.6%,64.6% and 70.7%,respectively.The operative time ranged from 80 to 150 minutes (average,130 minutes),and blood loss ranged from 150 to 600 ml (range,300 ml).One case of postoperative wound hematoma,1 case of cerebrospinal fluid leakage and 3 cases of trapezius muscle pain occurred in this group.No serious complications,such as deep infection,deterioration of neurological dysfunction,vertebral artery injury and internal fixation failure,were noticed.Conclusion Owing to the minimum interference to the cervical spinal cord,stabilization of the decompressed segments and maintenance of cervical lordosis,en bloc open-door laminectomy and pedicle screw fixation is suitable for extremely severe cervical OPLL.
