Objective To compare the anthelmintic effect of albendazole with that of triclabendazole against Fasciola giganti-ca. Methods Two patients infected with Fasciola gigantica were investigated,and one was administered with albendazole orally (200 mg,twice per day for 5 days)and another was administered with triclabendazole[10 mg/(kg?d)for 2 days]. Their total fe-ces were collected daily during the period of whole therapy,and the eggs of the parasite were collected by using the nylon bag method,and incubated at 28℃. Results The parasite eggs were detected from the first patient’s dejecta on the 1st,2nd and 5th day after the end of the treatment,and no miracidiums hatched out as well as no eggs developed during the period of 25 days of the incubation. Meanwhile,her body temperature fluctuated between 37.4℃and 38.3℃,and she still complained bellyache. For the other invalid,the eggs were not detected on the 2nd and 5th day after the end of the treatment. However,the eggs before and dur-ing the treatment developed the miracidiums of Fasciola gigantica on the 13th day after the incubation,but the eggs collected from the 1st day after the termination of the therapy did not develop and no miracidiums hatched out. At the same time,the signs and symptoms of the patient vanished after the 4th day of the end of the therapy. Conclusions Albendazole has no obvious insecticid-al activity on adult Fasciola gigantica in the short term,but may affect the development of eggs. Triclabendazole has the anthelmin-tic effect on the adults as well as eggs of Fasciola gigantica. In addition,triclabendazole has the characteristics of well curative ef-fect,short course of treatment,and no obvious side effects.

Objective To explore the application and significance of multiple clinical pathway training oriented teaching model in clinical teaching of laboratory diagnostic. Methods Totally 50 medical students enrolled in the Second Military Medical University from September to December in 2015 were divided into experimental group and control group. The course consists of theoretical teaching and experi-mental operation. The pathway group (n=25) were introduced into multiple clinical pathway training oriented teaching method. The theoretical teaching was carried out bysimulation examination application, simulation interpretation and simulation diagnosis and treatment, while the experimental course was carried out by using video teaching combined with actual operation. The control group was taught by traditional teaching method using slide teaching and operation display. The theoretical test including case study and operational skill tests were performed among students in both groups after 10 class hours training . The satisfaction questionnaires were conducted to evaluate the effectiveness and satisfaction of teaching guided by clinical pathway. Differences were compared with independent sample t testing using GraphPad Prism 5.0 statistical software. Results The medical records about professional theoretical test including case study and opera-tional skill test in the pathway group were superior to those in the control group with significant statistical difference (both P<0.05). The records of medical students were (81.84±7.21), (42.00±2.79) in the pathway group and (76.24 ±6.98), (37.00 ±3.71) in the control group. The questionnaire result showed that the pathway group's satisfaction was high, especially with the theoretical knowledge andsceneteaching (higher than 80％). The pathway group believed that multiple clinical pathway training helped to improve learning interest and clinical thinking ability . Conclusions Multiple clinical pathway training oriented teaching model is helpful for the medical students to achieve the basic idea of clinical pathway, improve the profes-sional ability, enhance the interest of learning and the quality of teaching, standardize teaching and promote teaching and learning.

This paper is to study the clinical characteristics of Brugada syndrome (BrS) in Chinese by analyzing clinical and ECG data of BrS patients. Data were included by computerized and manual research, and was analyzed by 2 doctors alone. The data of repetition and of non-Chinese were rejected. Forty-nine BrS patients were included (45 males and 4 females). Main manifestations included sudden death in 29 and syncope in 27 patients. Malignant ventricular arrhythmia (MVA) occurred in 14 of 17 patients with family history of sudden death or syncope and in 15 out of 32 ones without family history. Occurrence of MVA in 11 of 14 patients was within the period from 7pm to 7am. ECG revealed that sloped ST segment elevation appeared mainly in V1, V2 leads and coved ST segment elevation appeared mainly in V3 lead. BrS is not rare in Chinese people,and its clinical characteristics is similar to that overseas data.

Objective To explore the clinical value of nodal metastatic characteristics in predicting the distant metastasis of papillary thyroid carcinoma (PTC).Methods A total of 1 408 PTC patients who met the inclusion criteria and received initial thyroidectomy at our department from January 2006 to December 2011 were enrolled in this study.Results After a median follow-up time of 7.8 years,distant metastases developed in 46 patients.Patients with lateral neck lymph node metastasis ≥7,individual size of lateral neck lymph node metastasis ≥ 1.15 cm and the total number of cervical lymph node metastasis ≥9 were prone to higher risk of distant metastasis;the high risk group had a lower 10-year distant metastasisfree survival (78.7％ vs.98％,x2 =122.941,P ＜0.01) and a shorter distant metastasis-free survival time (99.2 M vs.122.5 M,x2 =122.941,P ＜ 0.01).Conclusions Lateral lymph node metastasis is an independent risk factor for distant metastasis in PTC patients.

Endodontic microsurgery is a vital treatment modality for teeth with persistent periradicular pathoses that have not responded to nonsurgical retreatment. The principle is to determine the reason for failure, completely eliminate the infection and promote periapical healing. Within recent years, endodontic microsurgery has evolved to become standardized and presents with a high success rate. However, its outcome is still influenced by many factors, including anatomy, periodontal condition, crown-to-root ratio, occlusion, the type of periradicular lesion, and prosthesis. Moreover, endodontists always concentrate on “the apex”, paying little attention to the general preoperative evaluation, accurate diagnosis, and comprehensive treatment plan. This article reviews the latest literature on these issues and the clinical experience of our research group and discusses the correlation between endodontic microsurgery and other oral disciplines, including periodontology, prosthodontics, oral implantology, oral and maxillofacial surgery and orthodontics. The oral interdisciplinary assessment should be made with comprehensive consideration of the root canal system, periradicular lesion, adjacent anatomical relationships, periodontal condition, occlusion, and esthetic rehabilitation. Based on these findings, the continuity of treatment will be optimized, and the best treatment plan will be proposed to provide clinical strategies for the diagnosis and treatment of complex periradicular diseases.
