3.Efficacy of oxcarbazepine monotherapy on adult patients with temporal lobe epilepsy
Chinese Journal of Postgraduates of Medicine 2016;39(11):992-994
Objective To observe the efficacy of oxcarbazepine monotherapy on adult patients with temporal lobe epilepsy (TLE). Methods Eighty-nine patients with TLE who were admitted to hospital from July 2011 to December 2014 were enrolled in this study. They had underwent surgery. Depending on the postoperative treatment they were divided into oxcarbazepine group (46 patients) and carbamazepine group (43 patients) group. They were treated by oxcarbazepine and carbamazepine after operation. The efficacy and complication were compared. Results The patients in two groups were followed up for 1.5 years. According to Engel grade, the number ofⅠ, Ⅱ, Ⅲand Ⅳ grade in oxcarbazepine group was 29, 10, 5 and 2 patients, in carbamazepine group was 26, 9, 5 and 3 patients, and there was no significant difference (P>0.05). The rate of adverse effect in oxcarbazepine group was 6.5%(3/46), in carbamazepine group was 20.9%(9/43), and there was significant difference (P<0.05). At the end of follow-up, the scores of generic quality of life inventory (GQOLI-74) in oxcarbazepine group was (74.6 ± 2.9) scores, in carbamazepine group was (65.1 ± 3.2) scores, and there was significant difference (t=9.838, P=0.000). Conclusions The efficacy of oxcarbazepine and carbamazepine shows no significant difference in adult TLE.But oxcarbazepine monotherapy has fewer adverse effects and more security.
4.Role of new emergency mode "Green track" in treatment of traffic injuries
Chinese Journal of Trauma 2010;26(7):617-619
Objective To explore the role of new emergency mode "Green track" in treatment on traffic injuries. Methods The data of 2 947 patients with traffic injuries rescued by prehospital emergency "green track" and inhospital emergency treatment from March 1998 to January 2009 were retrospectively studied in aspects of prehospital and inhospital treatment methods and their results. Results Of all patients, 2 089 patients were treated surgically and 858 patients treated conservatively, in which 2 736 patients (92.8%) were cured but 211 (7.2%) died, with mortality rate of 7.2%. Head, face and limbs were the main injury parts. Of all, 1 874 patients (63.6% ) were admitted into the hospital within one hour after injury. Conclusions The new emergency mode "Green track" , either prehospital or inhospital, can markedly improve success rate of treatment for traffic injuries, increase survival rate and is of importance to be clinically applied.
5.Effects of thermal and mechanical cycling on the metal-ceramic bond strength of machine-milled Ti2448 alloy and pure titanium.
West China Journal of Stomatology 2016;34(1):54-58
OBJECTIVETo evaluate the effects of thermal and mechanical cycling on the metal-ceramic bond strength of machine-milled Ti2448 alloy and commercial pure titanium (cp Ti).
METHODSCeramic-cp Ti (n = 30) specimens and ceramic-Ti2448 combinations (n = 30) were prepared in accordance with ISO 9693. The specimens from each metal-ceramic combination were randomly divided into three subgroups. In group A or the control group, the specimens were only stored in distilled water for 24 h at 37 °C; in groups B and C, the specimens were subjected to 3,000 cycles of thermal cycling between 5 and 55 °C for a dwell time of 60 s and to mechanical cycling of 20,000 or 40,000 cycles with 50 N load and 4 Hz in distilled water at 37 °C. A crack initiation test was performed using a universal testing machine in accordance with ISO 9693. Failure types at the metal-ceramic interface and the morphological and elemental composition of this interface were analyzed using a scanning electron microscope and an energy dispersive spectrometer. Statistical analysis was performed via two-way ANOVA and Tukey's adjustment test (α = 0.05).
RESULTSThe bond strength of the ceramic-Ti2448 combination was significantly higher than that of the ceramic-cp Ti combination regardless of fatigue conditions (44.86 MPa ± 1.75 MPa and 29.21 MPa ± 2.20 MPa for Ti2448 and cp Ti, respectively; P < 0.01). The mean bond strengths of ceramic-cp Ti and ceramic-Ti2448 combinations in group C were significantly lower than that of group A (P < 0.01). Although ceramic-cp Ti combination failed adhesively at the metal-ceramic interface without the ceramic on the substrate surface, Ti2448 frameworks exhibited cohesive failure; as a result, large amounts of residual porcelain were retained on the specimens.
CONCLUSIONThe metal-ceramic bond strength of cp Ti and Ti2448 is decreased by thermal and mechanical cycling.

7.Application value of serum tumor markers in diagnosis of pancreatic adenocarcinoma in the elderly
Chinese Journal of Geriatrics 2013;32(8):840-842
Objective To explore the clinical value of serum tumor markers including CEA,AFP,CA199,CA125,CK19,CA242 and CA724 in diagnosis of pancreatic adenocarcinoma in the elderly.Methods Totally 158 elderly and 102 middle-aged patients with pancreatic adenocarcinoma were selected.Pancreatic adenocarcinoma in all patients were confirmed by pathological examination,cytological examination and CT.100 elderly and 100 middle-aged patients with benign diseases were selected as control groups.The levels of serum tumor markers were detected and their sensitivities and specificities were calculated and compared between groups.Results The levels of serum CEA,CA199,CA125,CK19,CA242 and CA724 were higher in elderly patients with pancreatic adenocarcinoma than in the elderly control group [(70.9±11.4) g/L vs.(1.6±0.4) g/L,(158.9±19.1)U/mlvs.(12.6±3.2)U/ml,(53.9±15.4)U/mlvs.(11.6±1.1)U/ml,(70.2±16.3)U/ml vs.(1.4±0.2)U/ml,(96.4±18.5)U/ml vs.(7.9±2.2)U/ml,(57.6±13.6)U/ml vs.(4.4± 0.6)U/ml,t=26.13,31.63,17.57,19.03,20.95,15.59,respectively,all P<0.05].The sensitivities of serum CEA,AFP,CA199,CA125,and CA242 were higher in the elderly patients than in the middle aged patients (61.72% vs.48.69%,19.56% vs.4.13%,80.31% vs.69.55%,70.21% vs.46.77%,75.24% vs.59.44%,x2=4.28,12.63,3.94,14.32,7.23,respectively,all P<0.05).The specificities of serum CEA,AFP,CA199,CA125,and CA242 had no significant differences between the elderly and middle aged patients (all P>0.05).Conclusions Serum tumor markers may provide effective reference for the clinical diagnosis of pancreatic adenocarcinoma in the elderly,which has important value for pancreatic adenocarcinoma control and reversal.
8.Initial study of ultrasonography 5-grade system in the diagnosis of nasopharyngeal carcinoma
Chinese Journal of Ultrasonography 2013;22(11):950-953
Objective To explore the application of ultrasonography (US) 5-grade system in the diagnosis of nasopharyngeal carcinoma(NPC).Methods A total of 150 patients suspected of having NPC underwent ukrasonography and MR imaging.All the lesions were scored according to the two different methods.Pathological results were made the golden criteria.The diagnosis accuracy of ultrasonography and MR imaging for NPC was evaluated using receiver-operating curve (ROC) analysis by Medcalc software.Results Both ultrasonography and MR imaging exhibited a good diagnostic performance for NPC with area under the curve (AUC) values of 0.958 and 0.987,respectively.The AUC difference of the two methods were statistically significant(Z =2.827,P =0.005).Conclusions Ultrasonography 5-grade system was an initial quantitative criterion for nasopharyngeal carcinoma diagnosis.The diagnosis accuracy was high although lower than MRI.But it could provide an overall economical and convenient complementary technique for clinical diagnosis.
