On the basis of the analysis, suggesled are some improving measures, which are as follows: studying advanced educational theories and modern educational techniques; making courseware on carefully selected teaching content; setting up a scientific and effective estimating system.

The etiology and pathogen of diabetic cystopathy is mainly due to qi deficiency of spleen and kidney, which leads to bladder and Sanjiao hypo-function of vital energy, losing opening and closing. In addition to blood stasis injury essence, it blocks the urinary tract. The main pathogen is qi deficiency and blood stasis. The qi deficiency of spleen and kidney is the fundamental aspect, while the blood stasis is the surface aspect. Excess resulted from deficiency, intermingled deficiency and excess, belong to asthenia in origin and asthenia in superficiality. Clinical application of method of invigorating qi, removing blood stasis and eliminating stagnation for diabetic cystopathy has a good clinical efficacy.

Objective To evaluate the safety of myomectomy by extrusion in cesarean section , in comparison with routine cesarean delivery. Methods From January 2008 to December 2010, a total of 128 operations of myomectomy by extrusion in cesarean section were performed (Myoma Group), while another group of 128 cases undergoing caesarean section , which respectively followed every cases of the Myoma Group but had no hysteromyoma , was selected as the control group .The amount and rate of postpartum hemorrhage , the level of postpartum fever , and postoperative hospital stay between the two groups were compared , respectively. Results In the two groups:the amount of postpartum hemorrhage was (233.6 ±58.9) ml vs.(228.5 ±90.9) ml (t=0.530, P=0.597); the rate of postpartum hemorrhage was 0% (0/128) vs.0.8% (1/128) (P=1.000); the decrease of haemoglobin was (6.17 ±2.83) g/L vs.(6.89 ±3.09) g/L (t=-1.944, P=0.053); the decrease of hematocrit was 2.22%± 0.98%vs.2.27%±1.02% (t=-0.400, P=0.690); the rate of postpartum fever was 2.3% (3/128) vs.5.5% (7/128) (χ2 =1.665, P=0.197);the length of postoperative hospital stay was (4.2 ±0.8) d vs.(4.1 ±1.2) d (t=0.706, P=0.481). There were no significant differences between the two groups in the abovementioned parameters . Conclusions The myomectomy by extrusion in cesarean section does not increase the level of postpartum hemorrhage and the rate of postpartum infections .It is a simple, minimally invasive , safe and feasible surgical method , being worthy of clinical application .

Objective To analyze and summarize the MR findings of intraspinal primary melanocytie neoplasms.Methods Five cases of intraspinal primary melanocytic neoplasms were retrospectively analyzed with emphasis on the location,growth pattern and MR signal intensity features of the tumors.Results A total of six tumors were found in five cases (one case had two tumors).The tumors were located in the cercival spine (2),thoracic spine (2),thoracolumbar junction (2) respectively.One tumor was located in the intramedullary space and 5 tumors in the extrumedullary-intradural space.Growth of the tumors were limited in the intradural space without evidence of extradural extension.The intramedullary tumor exhibited hyperintensity on both T2WI and T1 WI.The intradural tumors showed hyperintensity on T1WI and hypointensity or isointensity on T2WI of various degree.Three of these tumors were predominantly hyperintense on T1 WI and homogeneously hypointense on T2WI.Conclusion The intraspinal primary melanocytic neoplasms could be diagnosed pre-operatively due to their unique signal intensity features on imaging.

Objective To study the changes in parameters of blood flow and frequency-spectrum appearance in superior mesenteric artery (SMA)and inferior mesenteric artery(IMA) in the patients with ulcerative colitis(UC). Methods The parameters of blood flow and frequency-spectrum of SMA and IMA in 16 cases of patients with UC were observed before and after treatment, and 10 healthy volunteers served as control. Results The parameters of blood flow of IMA in patients with left half colon UC (9 cases) and all colon UC (7 cases) significantly changed after treatment(P

Objective To study the expression of E-cadherin and ?-catenin in endometrial and endometriotic tissues of patients with endometriosis (EM) and to compare their expression in endometriosis at different stages. Methods Twenty-four EM patients were enrolled and the expression of E-cadherin and ?-catenin in endometrial and endometriotic tissues were determined by immunohistochemistry method. Normal endometrial tissue from 21 individuals was included as the control group. Results Compared with the control group, in E-cadherin and ?-catenin expression was shown in no difference between the secretory and the proliferative phase of endometrial tissue from EM patients. Furthermore, the expressions of E-cadherin and ?-catenin in normal endometrial tissue were stronger than that of EM patients(P

Objective Study the differential diagnosis value of the axis of "no man's land" in wide QRS complex tachycardia.Methods Retrospectively analyse the axis of "no man's land" in 137 patients with wide complex tachycardia who had undergone intracardiac electrophysiologic studies,use the algebraic sum of the deflections in leads I and III to plot the QRS axis,to observe the rule of arrhythmia of "no man's land" appearance.Results Eighteen of 137 patients who had wide complex tachycardia had the axis of "no man's land",among which 16 patients had left idiopathic ventricular tachycardia,and 2 patients had wide complex supraventricular tachycardia they had accessory pathway conduct anterogradely.Conclusion The axis of "no man's land" is helpful in differential diagnosis of ventricular and supraventricular tachycardias with abberency or bundle branch block.
