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.

Objective To investigate the clinical efficacy of imipenem and cilastatin sodium on the clinical efficacy of elderly patients with severe bacterial infection, and to observe the clearance rate to different floras.MethodsA total of 206 elderly patients with severe bacterial infection as the research object in our hospital outpatient treatment, were divided into control group and observation group, the patients were collected with sputum, blood and urine samples sent for bacterial culture.All patients were given positive treatment and nursing care, the observation group was given imipenem and cilastatin sodium treatment,the control group was given cefotaxime sodium treatment.The clinical efficacy, bacterial clearance and adverse reactions of the two groups were recorded and compared.ResultsThe total efficiency rate was 91.26% in the observation group, and 79.61% in the control group.The number of effective cases was significantly higher in the observation group than in the control group (P<0.05), the number of ineffective cases was significantly lower than that of the control group (P<0.05);The bacterial clearance rate was 85.71% in the observation group, and 43.33% in the control group, the clearance rate of Bauman Acinetobacter, Klebsiella pneumoniae, Pseudomonas aeruginosa and Staphylococcus aureus was significantly higher in the observation group than in the control group (P<0.05).Through the detection of adverse reactions showed that the observation group and the control group after treatment, few patients mild symptoms of nausea and vomiting and itching rash, on the occurrence of adverse reactions of the two groups of patients were compared, the difference was not statistically significant.ConclusionFor elderly patients with severe bacterial infection with imipenem and cilastatin sodium for treatment, the effective rate is high and can timely remove a variety of pathogenic bacteria, and rare adverse reactions, high safety, worthy of clinical application.
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.

6.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.

The emergence of drug resistance mutations in human immunodeficiency virus (HIV) genome is the major reason for antiviral treatments failure.To investigate the drug-resistance viral quasispecies in HIV-infected individuals and to find out the new drug resistance mutations have significant effects on directing effective clinical treatment and developing novel antiviral drugs.HIV drug resistance tests mainly include genotypic drug susceptibility assay and phenotypic drug susceptibility assay.We reviewed in this article some novel development in the field.
9. The value of CT and MRI in the detection of cerebral arachnoid granulations
Chinese Journal of Cerebrovascular Diseases 2006;3(1):27-30
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.
