[Objective]To explore the therapeutic effect of three surgical procedures(anterior approach,posterior approach and posterior-anterior approach) for cervical spondylotic myelopathy(CSM). [Methods]A total of 111 patients with cervical spondylotic myelopathy treated with three surgical procedures from June 2002 to December 2007 were retrospectively analyzed.Group A(anterior approach) comprised 54 patients with a mean age of 57.1 years(ranged,44~75 years).Group B(posterior approach,Laminoplasty) comprised 33 patients with a mean age of 61 years(ranged,41~73 years).Group C(posterior-anterior approach) comprised 24 patients with a mean age of 62 years(ranged,48-78 years).All patients were followed-up,neural function and cervical sagittal alignment were recorded.According to JOA score,preoperative and postoperative follow-up scores were compared,improvement rates were calculated,respectively.[Results]Patients were followed up for 3 months to 5 years with an average of 2 years.JOA scores of the three groups at 3,6,12 months and at the last follow-up after operation were compared with those of preoperation(P0.05).Cervical sagittal alignment(D numerical value) had no statistical difference at the postoperative and the final follow-up between group A and group C(P=0.434,P=0.492,P=0.569).There was significant difference between group B and group A/C(P

Objective To investigate the role of miR‐26a in ox‐LDL‐mediated apoptosis of HAECs in endothelial cells and its mechanism .Methods Various concentrations of ox‐LDL were added in HAECs culture .Cell cytotoxicity and apoptosis were moni‐tored by MTT and TUNEL assay ,and expression level of miR‐26a examined by qRT‐PCR .Overexpression of miR‐26a mimic in HAECs ,MTT and TUNEL staining were used to detect the activity and apoptosis of ox‐LDL .The 3′UTR of luciferase reporter vector pMIR‐PTEN was constructed and the predicted target gene of miR‐26a was identified by luciferase activity assay .QRT‐PCR and Western blot were used to detect the mRNA and protein expression of PTEN .Results ox‐LDL could mediate the toxic death and apoptosis of HAECs cells ,and decrease the expression level of miR‐26a in HAECs cells .Overexpression of miR‐26a mimic could inhibit the cytotoxicity and apoptosis of ox‐LDL cells after HAECs .Transfection of miR‐26a mimics significantly inhibited lu‐ciferase activity (P<0 .05) .The expression of mRNA and protein in HAECs cells was significantly down regulated by transfection of miR‐26a analog (P<0 .05) .Conclusion MiR‐26a can inhibit the cytotoxicity and apoptosis of ox‐LDL cells after HAECs inhibi‐tion ,and the possible mechanism of action is to down regulate the expression of PTEN .The study suggests that miR‐26a may be a potential target for the treatment of atherosclerosis related to apoptosis .

[Objective]To evaluate the curative effects of the posterior or anterior lumbar interbody fusion for the treatment of superior position intervertebral disc herniation. [Method] Forty-seven patients with superior position intervertebral disc herniation were followed up.There were 29 males and 18 females with mean age of 53.3 years(from 35 to 67 years).Twewty-five patients were treated with posterior lumbar interbody fusion(PLIF)using facet joint autograft and cage additional of pedicle screw internal fixation(posterior way group),and 22 patients were treated with anterior disckectomy,bone graft and plates internal fixation(anterior way group).The mean follow-up time was 53.5?5 months(from 24 to 78 months).The clinical results were compared between two groups.Clinical functional assessment standard was used to evaluate the clinical curative effect.The changes of the therapeutic effects,the radiographic findings and complications were evaluated.[Result]In regard to the operation time and bleeding,the posterior way group was superior to anterior way group.There was no difference between the two groups in clinical recovery rates and nerve root injury rates.Complications included dural tear(n=3),and pedicle screw deviating(n=1) in the posterior way group;and dural tear(n=2),unilateral transient lower extremity paresthesia(n=3),and hard controlled singultation(n=1) in the anterior way group.The rates of bone fusion were 96.00% and 95.45% in the posterior and anterior way groups. [Conclusion] Operation for the superior position intervertebral disc herniation is effective.The posterior lumbar interbody fusion using facet joint autograft and cage additional of pedicle screw internal fixation to shorten the operation time and decrease bleeding is recommend for the treatment of superior position intervertebral disc herniation.

Objective To study the alternation of coagulation and fibrinolysis in patients with gastric cancer(GC) . Method Platelet aggregation test(PAGT), prothrombin time (PT), activated partial thromboplastin time(APTT), tissue factor pathway inhibitor(TFPI), D-dimer and tissue plasminogen activator(t-PA: a)were detected in 48 GC patients(GC group) at two weeks pre- and post-operation respectively;and compared with non-tumor patients(control group). Results Compared with control group, in GC group,especially in GC patients with lymphatic metastasis,the PAGT increased (P

Objective To study the effect of magnesium citrate combined with compound polyethylene glycol electrolyte powder in bowel preparation before colonoscopy.Methods One hundred and six colonoscopy patients with lower digestive tract symptom were divided into study group (54 cases) and control group (52 cases) by random digits table method,the bowel preparation in study group was magnesium citrate combined with compound polyethylene glycol electrolyte powder,in control group was compound polyethylene glycol electrolyte powder.The lesions detection rate,bowel preparation quality,time of first defecation,number of defecation,time of colonoscopy,results of the electrolyte level and liver and kidney function after medication and adverse reaction were compared between two groups.Results There were no statistical differences in lesions detection rate,time of colonoscopy,results of the electrolyte level and liver and kidney function after medication between two groups (P ＞ 0.05).The total effective rate of bowel preparation quality in study group was significantly higher than that in control group [96.3％(52/54) vs.82.7％ (43/52)],the time of first defecation was significantly shorter than that in control group [(32.5 ± 26.1) rmin vs.(47.2 ± 22.4) min],the number of defecation was significantly much than that in control group [(8.2 ± 2.9) times vs.(6.2 ± 2.6) times],there were statistical differences (P ＜ 0.05).The incidence of nausea in study group was significantly lower than that in control group [22.2％ (12/54) vs.48.1％ (25/52)],there was statistical difference (P ＜ 0.05).There were no statistical differences in the incidences of vomiting,abdominal distention and abdominal pain between two groups (P ＞ 0.05).Conclusion Magnesium citrate combined with compound polyethylene glycol electrolyte powder used in preoperative bowel preparation for colonoscopy has better clinical application value.
