Objective:To test the periodontal regeneration potential after tooth root replantation combined with in vitro cultured periodontal ligament cells (PDLCs).Methods:The third and fourth mandibular premolars of two mongrel dogs were extracted and the dog PDLCs were in vitro cultured.The autologous roots combined with PDLCs were replanted into the created cavities in the right mandibular edentulous area one month after premolar extraction.Roots replanted without PDLCs on the left mandible served as the controls. The dogs were sacrificed 2 months after the replantation. Paraffin sections were made and stained with hematoxylin & eosin, then examined histologically.Results:In the samples of root combined with PDLCs implantation, some fiber bundles vertical to the surface of bone were embedded in some inner walls of the alveolar socket opposite to the apical root.Conclusion:Cultured PDLCs in vitro retain the capacity of PDL-like tissue formation even in the artificial alveolar socket.

OBJECTIVE: To investigate the cause, genetics, clinical features, pathological mechanism, diagonosis and treatment of the Giant pleomorphic adenoma of the parotid gland (GPA). METHOD: A case of GPA was reported and relevant literatures were reviewed. RESULT: GPAs were more commonly found in elderly patients, duration of more than 10 years, with a possible malignant degeneration. CT scan shows uneven density, different degrees of enhancement and clear boundary. Pathological examination shows that the composition of tumor tissue are epitheli al cells, myoepithelial cells and mucus. CONCLUSION GPA is an uncommon disease and is associated with human factors. The diagnosis of GPA is oriented by medical history, physical examination and imaging tests. The total resection of the tumor and preservation of the facial nerve is an effective way for the treatment of GPA.

Objective To assess the predictive value of coronary angiography TIMI myocardial perfusion grade (TMPG), electrocardiogram (ECG) single-lend ST segment resolution (STR), ECG Max-ST-segment deviation (MaxSTE) on judging myocardial reperfusion after primary angioplasty in the patients with acute myocardial infarction (AMI). Methods Primary percutaneous coronary intervention(PCI) was performed in 42 patients within 12 hours after AMI onset. Coronary angiography and ECG was done before and after angioplasty. TMPG, ECG single-leed STR and MaxSTE were used to assess myocardial reperfusion immediately after PCI. Myocardial perfusion scan was examined in all the patients using99mTc-MIBI SPECT on day 7±2. Results Compared with the level of myocardial perfusion demonstrated in myocardial scan of 99mTc-MIBI SPECT, the sensitivity, specificity and accuracy of TMPG, single-lead STR and MaxSTE was calculated. The sensitivity of TMPG, single-lead STR and MaxSTE was 93.75%, 87.50% and 81.25%, respectively, the specificity of them was 20.00%, 80.00% and 80.00%, respectively, and the accuracy was 76.19%, 85.71% and 80.95%, respectively. The findings in single-lead STR and MaxSTE matched well with the results of myocardial scan of 99mTc-MIBI SPECT. Conclusion In the patients suffering from AMI treated with PCI, ECG is an effective method to assess myocardial tissue reperfusion.

Objective To investigate the effect of malignant tumor on neuromuscular block of cisatracurium. Methods Sixty ASA Ⅰ or Ⅱ patients with head and neck neoplasms (15 cases with benign tumor, 45 with malignant tumor), aged 18-64 yr, were randomly divided into 4 groups ( n = 15 each): Ⅰ benign tumor group (group B,3 × ED95 ); Ⅱ -Ⅳ different dose cisatracurium group (group C1 (2 × ED95 ), C2 (3 × ED95 ) and C3 (4 ×ED95)). Neuromuscular block was assessed with accelerograph F (TOF-watch SX). Single stimulation of ulnar nerve was used. Anesthesia was induced with TCI of propofol (target plasma concentration 3 μg/ml) and remifentanil (target effect-site concentration 3 ng/ml). Tracheal intubation was facilitated with cisatracurium 0.15 mg/kg in group B, and with cisatracurium 0.10, 0.15 and 0.20 mg/kg in group C1, C2 and C3 respectively. The onset time, clinical duration, time for recovery of T/Tc to 75 % and recovery index were recorded. Results The clinical duration, time for recovery of T/Tc to 75 % and recovery index were significantly longer in group C2 than in group B (P ＜ 0.05). The onset time was significantly shorter, while the clinical duration and time for recovery of T/Tc to 75% were significantly longer in group C2 and C3 than in group C1 , and in group C3 than in group C2 ( P ＜0.05) .Conclusion The duration of action and recovery times of cisatracurium were prolonged in patients with malignant tumor.

Objective To investigate the protective effect of taurine on primary cultured neonatal rat myocardial cells and the inhibitory effect on cardiac fibroblast proliferation.Methods The myocardial cells were divided into six groups:control group,H_2O_2 damage group,H_2O_2 damage group treated with ligustrazine and H_2O_2 damage group treated with taurine with different doses(80,40 and 20 mmol?L~(-1)).Morpholoical changes of myocardial cells damaged for 6 h by 0.5 mmol?L ~(-1) H_2O_2 under the inverted microscope were observed.Meanwhile,cell survival ability and the contents of LDH,SOD and MDA were measured.Cardiac fibroblasts were randomly divided into(7 groups) and co-cultured for 72 h with taurine with doses of 0,10,20,40,80,160 and 320 mmol?L~(-1) and proliferation ability was assessed by MTT method.Results Absorption values in H_2O_2 damage groups treated with taurine(80,40 and 20 mmol?L~(-1)) were 0.479?0.055,0.437?0.052 and 0.421?0.062,respectively.They were higer than that in H_2O_2 damage group(0.304?0.050)(P

Objective To evaluate the efficacy of combined anterior and posterior approaches in treatment of severely unstable lower lumbar burst fractures.Methods A retrospective case series study was made on clinical data of 14 patients with lower lumbar burst fractures collected from August 2009 to August 2014.There were 12 males and 2 females,with a mean age of 39 years.Seven fractures occurred at L3,five at L4,and two at L5.Nine patients were associated with injury to the posterior ligament complex (PLC).According to the American Spinal Injury Association (ASIA) classification,the spinal injuries were rated as grade B in two patients,grade C in four,grade D in five and grade E in three.All patients underwent posterior pedicle screw fixation combined with anterior spinal canal decompression and titanium mesh or iliac bone grafting.Lumbar lordosis angle,vertebral height,spinal canal decompression,ASIA grade and complications were evaluated after operation.Results Two patients experienced cerebrospinal fluid leakage postoperatively,which were healed after 2 weeks' local pressure treatment.Three patients experienced recurrent lumbar pain postoperatively,which were relieved after the removal of internal fixation 18 months after operation.All patients were followed up for 12-36 months (mean,18 months).Compared to the detection before operation,final follow-up showed improved lumbar lordosis [(30.2 ± 7.3) ° vs.(41.3 ± 6.5) °],decreased loss of the anterior vertebral height [(62.3 ± 21.5) ％ vs.(11.8 ± 7.8) ％] and reduced canal compromise [(65.7 ± 30.5) ％ vs.(21.9 ± 12.7)％] (all P ＜ 0.05).ASIA grade was significantly improved at the final follow-up,including grade C in one patient,grade D in three and grade E in ten (P ＜ 0.05).Follow-up showed no apparent graft loosening,pseudarthrosis,implant breakage and severe kyphosis.Conclusion Combined anterior and posterior approaches to treat severely unstable lower lumbar burst fractures can effectively reconstruct the height and stability of the vertebral body,restore the spinal canal volume,and attain satisfactory clinical outcome.

Objective To evaluate the left ventricular (LV) systolic dyssynchrony after the acute myocardial infarction (AMI) with two-dimensional speckle tracking echocardiography (STE). Methods STE were performed in 65 patients within 72 h of AMI and compared with 60 age- and sex-matched healthy volunteers. The peak longitudinal strain (LS_(peak)) was measured at LV myocardium. LV dyssynchrony was defined as an interval ≥130 ms for the absolute difference in time to peak radial strain for the anteroseptal wall versus the posterior wall (TAS-POST). Size of myocardial infarction (MIS)was confirmed by wall-motion score index (WMSI). Results The LS_(peak) and LV ejection fraction (LVEF) were lower, and WMSI and TAS-POST were larger in AMI patients compared with controls. Forty-two patients had developed LV dyssynchrony (64.62%), and there were strong correlation between LV dyssynchrony (TAS-POST) and LS_(peak), LVEF, and WMSI (MIS). MIS was the most independent predictor for systolic dyssynchrony. Conclusion AMI with normal QRS can induce LV dyssynchrony, which is mainly determined by MIS. STE is a reliable technique for accurate evaluation of LV synchrony.

Objective To investigate the effects of sufentanil,remifentanil and fentanyl oH cellular immune function in patients undergoing radical resection of esophageal cancer.Methods Forty-five ASA Ⅰ or Ⅱpatients aged 45-64 yr undergoing radical resection of esophageal cancer were randomly divided into 3 groups(n=15 each):sufentanil group(SF);remifentanil group(RF)and fentanyl group(F).The patients were premedicated with iv atropine 0.5 mg.Anesthesia was induced with midazolam 0.04 mg/kg,propofol TCI(CT=3μg/ml)and TCI of sufentanil,remifentanil or fentanyl(CT=0.5,5 and 5 ng,ml respectively in the 3 groups).Endobronchial intubation was facilitated with vecuronium 0.1 mg/kg.The patients were mechanically ventilated.PETCO2 was maintained at 30-40 mm Hg.Anesthesia was maintained with inhalation of sevoflurane(0.7-1.5 MAC)and TCI of sufentanil,remifentanil or fentanyl(CT=0.5,5 and 5 ng/ml respectively).Venous blood samples were taken from peripheral vein before anesthesia(T0,baseline),60 min after skin incision(T1),immediately(T2),24 h(T3)and 72 h(T4)after the end of operation for determination of the expression of CD3+,CIM+,CD8+on T cells and CD3-CD16+CD56+on natural killer cells by flow cytometry,CD4+/CD8+ratio,serum concentrations of IL-2 and IL-10 by ELISA.Results Compared with the baseline values,the CD4+T-lymphocytes and CIM+/CD8+ratio were significantly decreased at T2,while the CD3-CD16+CD56+NK cells were significantly increased in all 3 groups.The CD3+T-lymphocytes were significantly decreased at T2 as compared to the baseline value at T0 in SF and RF groups.The CIM+and CD3+T-lymphocytes were significantly decreased at T3 as compared with the baseline value in all 3 groups.Serum IL-2 concentration was significantly higher at T3 in SF group than in RF group.Serum IL-10 concentration was sismficantly higher at T4 in RF group than in SF group.Conclusion Sufentanil,remifentanil and fentanyl can depress cenular immune function to some extent in patients undergoing radical resection of esophageal cancer.
