It is to difficult to diagnose and treat hepatobiliary surgical diseases since its diverse clinical manifestations,which increases the difficulty of clinical internship.Taking clinical cases as teaching material,case-based learning was combined with teaching theme and was conducted by means of discussion and question and answer between teachers and students.Students can know about concepts or theories related to teaching theme.Case-based learning in internship can consolidate basic knowledge of hepatobiliary surgery,cultivate clinical scientific thinking and is helpful in analyzing and resolving problems of hepatobiliary surgical diseases.

Background Excimer laser corneal refractive surgery is one of the major methods to correct refractive error.Centration of the ablation zone is an important factor that affects visual quality after surgery.The pupil center and its shift is a major factor to determine the ablation center.Therefore further study on pupil centroid shift with illumination level alteration is needed.Objective This study aimed to study the characteristics of the pupillary centroid shift along with the change of pupil size under the different illumination conditions and the possible clinical application of the curve of pupillary centroid shift in exeimer laser corneal refractive surgery.MethodsThe variation of pupil size induced by illumination and the changes of pupil center were measured on 114 moderate myopia eyes of 57 subjects with Astra MaxTM Corneal Topographer.Illumination of placido target and image snap model of the topographer was customized to provide 5 illumination levels as follows:0.8,4.4,18.9,82.3,355.0 Lx.Vectorial analysis was used to graph the change of pupil center related to the Coaxially Sighted Corneal Reflex (CSCR).Raw data is converted to relative value to analyze the pupiilary centroid shift.The mean relative change of the pupil size(△P)and the mean of relative pupillary centroid shift(△C)in the form of percentage were used to attenuate the variation among subjects.The original value of illumination(darkest)is defined as 0％ and maximum value(lightest)was as 100％.Results With the increase of illumination,the shift of the pupil center towards nasal side when pupil constrict was found.The mean change of pupil size under the 5 illumination levels were 0,(1.28 +0.40)mm,(2.34 ±0.53)mm,(3.34+0.54)mm,(4.03 ±0.56)mm respectively,and the △P values was 0％,32％,58％,83％,100％ respectively.The mean of pupil centroid shift under the 5 illumination levels were 0,(78±33)μm,(116±60)μm,(143 ±66)μm,(170±71)μm respectively,and the △C was 0％,46％,68％,84％,100％respectively.There was a linear relation between the relative pupil centroid shift and the relative change of pupil size (r=0.980,P=0.025).The amount of pupil centroid shift has a positive correlation with amplitude of the change of pupil size(r=0.480,P＜0.01).Conclusion Pupil center shifts with the change of pupil size.The linear relation between relative pupil centroid shift and the relative change of pupil size can be applied in eximer laser corneal refractive surgery to improve the visual quality with customized ablation center location.

OBJECTIVE:To observe the efficacy and safety of olanzapine combined with ziprasidone in the treatment of refrac-tory schizophrenia in elderly patients. METHODS:120 elderly patients with schizophrenia were randomly divided into control group and study group. Control group was orally treated with Olanzapine tablet 10-20 mg,once a day;study group was orally treat-ed with Ziprasidone hydrochloride capsule 80-120 mg,twice a day+Olanzapine tablet(the usage was the same as control group). The clinical efficacy in 2 groups was evaluated after 2 weeks,PANSS score,FPG,2 h PG,TC,TG,HDL-C,LDL-C,body weight, BMI before and after treatment and incidence of adverse reactions were observed. RESULTS:There were no significant difference in the total efficacy and incidence of adverse reactions between 2 groups(P>0.05). After treatment,the PANSS scores at different time point in 2 groups were significantly lower than before,and 12 weeks<8 weeks<4 weeks<2 weeks,the differences were sta-tistically significant(P<0.05),however,there was no significant difference between 2 groups(P>0.05). There were not signifi-cant differences in the indexes of blood glucose and lipid,body mass and BMI in study group before and after treatment (P>0.05);after treatment,the blood glucose after 8 and 12 weeks and LDL-C,TG,TC,body mass and BMI after 4,8 and 12 weeks in control group were significantly higher than before and study group same time,the HDL-C was significantly lower than before and research group,the differences were statistically significant(P<0.05). CONCLUSIONS:The efficacy and safety of both olan-zapine combined with ziprasidone and olanzapine alone in the treatment of refractory schizophrenia in elderly patients is similar, however,it is better than olanzapine alone in terms of controlling blood glucose and lipid.

Objective To study the MRI findings of HE and the pathological mechanism and to improve the diagnosis and differential diagnosis of HE. Methods Five patients of HE diagnosed by clinical and laboratory examination were examined with conventional MRI scan. Additional DWI, MRA and enhancement MRI scan were performed on 3 patients in which abnormal findings was detected on the conventional MRI. The distribution of lesions and signal characteristics were analyzed. The ADC values of the lesions and of the contralateral non-lesion area were measured. Moreover, the possible pathological mechanisms of HE were discussed on the basis of changes of clinical and imaging manifestations in the two cases with serial clinical and MRI data. Results Of 5 patients, brain abnormalities were found in 3 cases,which showed scattered spotted supratentorial white matter lesions of isointensity on T1 WI and DWI, and high signal intensity on T2WI and fluid-attenuated inversion recovery (FLAIR). Meanwhile, multiple plaque-like lesions involving both white matter and gray matter were found, mainly located at the basal ganglia nuclei, hippocampus and cingulate cortex. The lesions demonstrated iso-or hypo-intensity on T1 WI,and iso-or hyper-intensity on T2 WI, FIAIR and DWI at the initial stage. No enhancement was found in these lesions and MRA disclosed no remarkable findings. The ADC value of the lesions [ (0. 449 ± 0. 092) ×10-3 mm2/s] was decreased significantly compared with the contralateral noninvolved area [ (0. 838 ±0. 062) × 10-3 mm2/s] at the early onset. In 2 cases with glucocorticoid therapy, together with symptom relief, MRI follow-up scan demonstrated the reduction of lesion volume, the signal change to hyperintensity on T1 WI and hypo-intensity on DWL The ADC of the lesions increased significantly. Conclusion The MRI could be one of the effective tools for diagnosis, differential diagnosis, and judging the prognosis and therapeutic results of HE. Meanwhile, it may be a non-invasive method to study the pathological mechanism of HE.
