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.

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.

Objective: To evaluate shaping ability of nickel-titanium rotary instruments (Hero 642) in curved root canals. Methods:The computer assistant measure system of simulated root canal was used for quantitative analysis of root shape in eight simulated root canals during nickel-titanium rotary instruments (Hero 642) shaping process. Results:Nickel-titanium rotary instruments (Hero 642) could keep the curved angles in simulated canals very well. The cutting of Hero 642 in curved root canals was balanced and there was almost no transportation of canals central lines when the simulated canals were prepared to 0.02 taper 25~# and 30~# files. Conclusion:Nickel-titanium rotary instruments (Hero 642) has good shaping ability. In preparation of highly curved canals, the master apical file (MAF) may be Hero 642 0.02 taper 30# files.

According to the relative data of the patents awarded in the field of Chinese materia medica (CMM) announced by State Intellectual Property Office of P. R. China during 1998-2003, the amounts of CMM patents awarded with different types, compounds and active constituents, and service and non-service patents of CMM were compared and analysed. The amounts of inventive CMM patents have been more than that of the patents of utility model and design, the patents of CMM compound have greatly exceeded the patents of active constituent of CMM. Non-service patents of CMM has absolute predominance compared with the service patents. However, percentage of patents of active constituents and service patents of CMM are important targets to measure the creativity of CMM patents. This difference has reflected the present situation of CMM in China-lack of creativity. Based on the authentication of CMM creative patent, the cause of the above-mentioned situation has been analysized, and that our Patent Law should perfect the criterions of the CMM creative patent has been proposed so as to encourage the individuals and enterprises to advance the creativity of CMM in skills furtherly and strengthen the ability of protecting Intellectual Property Right and power of international competition for CMM.

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.

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.

Objective: To evaluate the diagnostic utility of CT and MRI in the detection of arachnoid granulations located in cerebral venous sinuses. Methods: MRI were applied in 8 patients for detection of arachnoid granulations, 7 of them also underwent CT scan. All of the images were analyzed retrospectively. Results: There were 9 arachnoid granulations found in the 8 patients. 6 of them were located in transverse sinus while 3 in superior sagittal sinus. 7 arachnoid granulations were manifested low density in CT, 3 of them with calcification. All of 9 arachnoid granulations showed low signal in T1WI and high signal in T2WI of MRI. 7 of them showed low signal in Flair sequence, 4 showed mild or moderate enhancement and filling defect sign. Filling defect was seen in cerebral MRV in 4 cases. Conclusion: Both CT and MRI are reliable methods to verify arachnoid granulations, but MRI is more useful in identifying their relation with venous sinuses.
