Objective: To investigate the root canal configuration and the incidence and location of the isthmus in extracted maxillary second premolar with single root. Methods: 60 maxillary second premolars were included in the study. 1 mm root was cut from the apical end of root. The transverse section was stained with methylene blue dye and viewed with a surgical operating microscope. 1 mm increment sections were made and stained and observed by the same way from apex to 6 mm. The number of canals as well as the type of canal isthmuses were recorded. Results: 41.67% maxillary second premolar with single root had two canals. Canal isthmus happened more frequently in the apical 4 mm levels. Conclusion: The incidence of isthmus in the maxillary second premolar was highest in the apical 3-to 5-mm level. Canal morphology in the apical 1-to 6-mm is complicated.

[Objective] To discuss effective way for Prominent Lumbar Intervertebral Disc.[Method] Apply shinbone tube seal and dimensional traction on 118 cases of the said patients.[Result] After following up for 3~18 months,62 cases were very good,occupying 52%;43 good,36%;10 bad,8%;no effect 3,2%,the effective rate 88%.[Conclusion] It is safe and one of good therapies presently to treat Prominent Lumbar Intervertebral Disc with shinbone tube seal and dimensional traction.

A total of 446 hyperuricemic patients were divided randomly by community-based cluster sampling into study (n =228) and comparison (n =218) groups.After 12-month health interventions,the Knowledge-Attitude-Performance (KAP) questionnaire [(19.0±4.7) points],lifestyle (balanced diet,modest physical exercises & regular monitoring) self-report questionnaire [attitudes prevention awareness:(8.3 ± 6.1) points,disease self-management behaviors:(13.2 ± 9.8) points],uricacid index [(395 ± 46)mmol/L] and body mass index (BMI) [(23.1 ± 2.3)kg/m2] were better than those at pre-intervention in study group [(9.3 ± 2.7),(4.6 ± 3.9),(7.4 ± 6.4)],[(420 ± 44)mmol/L,(24.9 ± 1.6) kg/m2] (P ＜ 0.05).Also the inter-group difference had statistical significance (P ＜ 0.05).It suggests that health intervention management is both feasible and effective in improving the KAP of patients,modulating lifestyles and lowering the levels of uric acid index and BMI.

AIM: To observe the clinical effect of Ex - press glaucoma filtration device implantation under scleral flap for traumatic glaucoma.
METHODS: Totally 19 eyes of 19 patients with traumatic glaucoma were implanted with Ex - press glaucoma filtration device under the scleral flap from December 2012 to May 2013. The postoperative visual acuity, anterior chamber depth and hyphema,intraocular pressure(IOP), filtering bleb and other complications were observed and summarized.
RESULTS: Ex - press glaucoma filtration device were implanted successfully in 19 patients. At 1d postoperatively shallow anterior chamber was occurred in 2 eyes and hyphema was occurred in 3 eyes. At 3mo postoperatively increased vision was occurred in 9 eyes (47%),functional filtering bleb was occurred in 18 eyes ( 95%), and IOP was 12. 1 ± 6. 1mmHg. At 6mo postoperatively increased vision was occurred in 11 eyes (58%),functional filtering bleb was occurred in 18 eyes (95%),and IOP was 13. 3±6. 9mmHg. Compared with the preoperative IOP ( 29. 8 ± 6. 7mmHg), the difference was significant(P<0. 05).
CONCLUSION: Ex - press glaucoma filtration device implantationfor traumatic glaucoma can improve the postoperative vision and control the postoperative IOP stably with fewer complications and high safety.

Objective To study the clinical effect of cervical loop electrosurgical excision procedure (LEEP) in diagnosis and treatment of cervical diseases (including cervical intraepithelial neoplasia of different grade, cervical erosion of moderate and severe degree, cervical with human papillomavims (HPV) infection and cervi-cal polyp) . Method The data of 136 cases with cervical disease treated by LEEP were analyzed retrospectively. Re-sult The postoperative diagnosis were upgraded in 18 cases (13.2%) ,and downgraded in 38cases (27.9 %) . The preoperative diagnosis of 80 cases (58.8 %) were in accordance with the postoperative ones. The difference was sig-nificant(P<0.05). The mean operative time was 11minutes, the mean bleeding volume was 15 ml. Postoperative bleeding of LEEP occurred in 2.2 % (3/136) patients. Postoperative cervical conglutination of LEEP occurred in 1. 5 % (2/136) patients. The cure rate of CIN was 96 % after LEEP. The residual CIN occurred in 4 patient (4 %). Recurrence CIN occurred in 2 patient (2 %). At 12th months after LEEP,the negative rate of HPV detection was 86. 7% and the persistent positive rate was 13.3%. The HPV clearance rate was increased gradually after LEEP. Conclu-sion LEEP was safe and effective for the treatment of the cervical disease and was a kind of good method to clear HPV infection in cervical.

Continuing medical education is one of major parts in medical education system of minimal invasive surgeon. Based on the characteristics of net continuing medical education such as freedom of learning, no regional restriction and abundant resource, combined with visualized teaching of minimal invasive surgery education, the novel training model of e-learning based on internet was applied to establish minimal invasive surgery continuing education system.
