ObjectiveTo evaluate the effects of intense pulse light (OPT) on the facial pore widening of different parts.MethodsThirty six women with widened pores were enrolled,and treated by OPT for 6 times.All the cases were taken photos before and after treatment.The pores of cheek,nasal ala and nasal tip were graded by using the photographic scale,and the improvement after treatment compared with that before.ResultsThe cheek,nasal ala and nasal tip pores evidently diminished (P＜0.01).The improvement rate of cheek pores was higher than that of nasal ala and nasal tip (P＜0.01),but that between the latter two was not different (P＞0.05)).ConclusionsThe cheek pore widening diminishes more significantly than nasal ala and nasal tip treated with OPT.

Objective To explore a suitable method to estimate the quantity of removing skin in double-fold eyelid operation.Methods Upper eyelid skin gently pulled towards eyebrows was flattened with the eyelash being slightly curved,the double-fold eyelid line that was parallelled to blepharitis was marked at 6-7 mm far from blepharitis.Then opening eyelid and looking upwards,the suprapalpebral fold was formed,and several dots were marked on the fold margin. After slightly closing eyelid the suprapalpebral fold margin line was formed through connecting the dots.The skin between the two line was the quantity to remove in operation.If the two line overlaped,removing skin did not need.Results A total of 89 cases were enrolled in this study.The patients were followed up from three months to one year,and the results showed that 67 cases were satisfactory,22 cases were basically satisfatory,and no one was not satisfactory.Conclusions The designing method for removing skin according to double-fold eyelid line and suprapalpebral fold margin line is a good method to estimate the quantity of removing skin in double-fold eyelid operation.

Objective To compare the improvement of peri-orbita rhytides and the patients' satisfaction treated by intense pulse light, Elos and activeFXTM fractional CO2 laser. Methods Two groups of the study were conducted. In first group, 42 volunteers in the hospital were enrolled. All were took photos to evaluate the peri-orbita rhytides by the physician before and one month after activeFX? treatment. Doctors and volunteers evaluated the improvement of peri-orbita rhytides and satisfaction together. In second group, a retrospective study was conducted, in which 40 patients were treated with intense pulse light, and other 40 patients treated with Elos in 2006-2007. Their improvements were analyzed through comparison of their photos before and one month after treatment, and the satisfaction was also evaluated. All data were analysed by SPSS10. 0. Results ActiveFXTM fractional CO2 laser is better than other two techniques for improving peri-orbita rhytides, and patients were more satisfied with this technology. Conclusion The improvement of peri-orbita rhytides and satisfaction treated by activeFXTM is higher than intense pulse light and Elos techniques.

OBJECTIVETo explore the reasonable therapeutic strategy for different types of epicanthus.

METHODSPatients with epicanthus were classificated according to the shape, extent and inner canthal distance and treated with different methods appropriately. Modified asymmetric Z plasty with two curve method was used in lower eyelid type epicanthus, inner canthus type epicanthus and severe upper eyelid type epicanthus. Moderate upper epicanthus underwent '-' shape method. Mild Upper epicanthus in two conditions which underwent nasal augumentation and double eyelid formation with normal inner canthal distance need no correction surgery. The other mild epicanthus underwent '-' shape method.

RESULTSA total of 66 cases underwent the classification and the appropriate treatment. All wounds healed well. During 3 to 12 months follow-up period, all epicanthus were corrected completely with natural contour and unconspicuous scars. All patients were satisfied with the results.

CONCLUSIONSClassification of epicanthus hosed on the shape, extent and inner canthal distance and correction with appropriate methods is a reasonable therapeutic strategy.

Objective To investigate the effect of taking medical students as standardized patients(SSP) on problem based leaming(PBL) teaching in clerkship.Methods Totally 161 students (grade 2008) selected from clinical medical department was divided into PBL group(n=81) and lecture-based learning(LBL) group(n=80).SSP was introduced into PBL teaching and LBL group was taught by LBL.After the clerkship,theory test was conducted in two groups and questionnaire was given to LBL group.Statistical analyses were conducted by SPSS 13.0,measurement data were analyzed by t test and enumeration data were described by frequency and constituent ratio.Results Theory test results showed that the average score of medical record analysis was (37.35 ± 5.95) in PBL group,much higher than (33.25 ± 4.89) in LBL group(P=0.001) ;the total score was (71.20 ± 8.67) in PBL group,much higher than that of (67.79 ± 9.87) in LBL group(P=0.018) as well.The average scores of choice question in 2 groups were (33.85 ± 5.05) and (34.24 ± 6.87),without significant differences(P=0.658).The constituent ratio of answer ‘OK' regarding 10 entries in questionnaire was more than 75％.The constituent ratio of answer ‘OK' regarding 3 entries(SSP matching degree,SSP without implied language or action,stimulating the learning interest) was more than 90％.Conclusions Introducing SSP PBL teaching can improve students' ability of clinical analysis and problem solving but not so effective for the basic theoretical knowledge grasp.SSP could replace standardized patients in PBL teaching.

Objective To explore the clinical characteristics and diagnostic methods of cerebral schistosomiasis.Methods The data of CT,MRI and the cerebral spine fluid(CSF) immunoassay in 42 patients with cerebral schistosomiasis were analyzed retrospectively.Results Forty cerebral schistosomiasis patients were diagnosed by the iconography and immunoassay,1 by the postoperative pathological examination and 1 by diagnostic treatment with praziquantel.Conclusions CT and MRI are of great value to determination of the position and nature of the cerebral schistosomiasis.The sensitivity and accuracy of MRI are better for indicating the main pathological changes of the disease than those of CT.The CSF immunoassay plays an important role in the differential diagnosis of cerebral schistosomiasis.
