As one of the first resident standardized training bases, department of ophthalmology of Shanghai Ruijin Hospital participated in this reform process from 2010. Relevant rules and regulations (training management system , training scheme implementation system and evaluation system ) were strictly obeyed. When new problems emerged, under the guidance of department in charge, a series of regimens were formulated and improved gradually by Ophthalmology Professional Committee of Shanghai Resident Standardized Training Department. Based on reviewing and summarizing the work in the last 3 years, some thoughts and suggestions on the resident standardized training in future were put forward ,in-cluding how to better solve the“heavily used, lightly cultured” problem, the“disregarding medical ethics establishment”problem, the“disregarding assessment of teachers”problem and the“disregard-ing obtaining employment”problem.

Objective To evaluate the CT features and the role of CT in the diagnosis of Crohn′s disease. Methods CT manifestations of 18 patients with pathology confirmed Crohn′s disease were retrospectively analyzed. The majority of the patients were scanned with spiral CT or multidetector row CT.Results All 18 patients, segmental thickening of the bowel wall was detected. There were two different appearances in contrast-enhanced CT scans: (1) mural thickening without enhancement or mural stratification, and homogeneous attenuation in the thickened wall were observed in 7 patients; (2) mural thickening and stratification, resulting in the target or double-halo appearance, were detected in 11 patients, and the bowel wall thickening ranged from 5 to 10 mm. Nine patients had perienteric abnormalities including fibrofatty proliferation, phlegmon and mesenteric hypervascularity. According to the CT manifestations, 5 patients were initially diagnosed as other diseases including intestinal obstruction (1 case), tuberculosis (1 case), cancer (2 cases), and abscess (1 case), respectively. Conclusion CT has the unparalleled ability to depict the abnormalities in the bowel wall, mesentery, abdominal and pelvic viscera, and contrast-enhanced CT can distinguish active Crohn′s disease from quiescent Crohn′s disease. These features make CT particularly valuable in the management of Crohn′s disease.

Objective To evaluate the effect of curcumin on diabetic neuropathic pain (DNP) in rats. Methods Forty-eight male SD rats weighing 200-230 g were randomly divided into 6 groups ( n = 8 each) : group Ⅰ normal control (group C); group Ⅱ DNP (group D) ; group Ⅲ DNP+ DMSO (solvent of curcumin) (group DD) and group Ⅳ , Ⅴ , Ⅵ DNP + curcumin 50, 100 or 200 mg/kg ( group DC50, 100, 200 ). Diabetes was induced with intraperitoneal (IP) streptozocin 75 mg/kg in group Ⅱ -Ⅵ. Curcumin 50, 100 and 200 mg/kg were given IP once a day for 14 consecutive days starting from 14 d after streptozocin in group Ⅳ , Ⅴ and Ⅵ respectively. Venous blood samples were taken before and 72 h after IP streptosocin for determination of blood glucose level. Successful induction of diabetes was defined as blood glucose > 14.6 mmol/L. Mechanical paw withdrawal threshold to yon Frey stimuli (MWT) and paw withdrawal latency to thermal nociceptive stimulus (TWL) were measured 2 d before and 14 d after IP streptesocin and on the 1, 3, 7, 14 d of curcumin administration. Animals with pain threshold measured at 14 d after IP streptozocin decreasing by less than 15% of the baseline were excluded from the study. The animals were sacrificed after the last pain threshold measurement and the lumbar segment of the spinal cord and p65 was significantly higher in group D than in group C ( P < 0.05). Curcumin administration significantly reduced thermal and mechanical hyperalgesia induced by diabetes and down-regulated the expression of p-JNK and horn and DRG.

Objective To study the effect of Xuebijing injection on the change of intestinal tract mucosa barriers and the expression of macrophage antihody in rats with sepsis. Method Totally 150 Wistar rats were ran-domly divided into three groups: sham group, sepsis group, and Xuebijing group. Sepsis models were estabhshed in rats by cecal ligation and puncture. The success standards of sepsis included fever, the increase of respiration rate,increased heart rate and change in leukocyte count. At 12 hours before operation, and after operation the rats in the Xuebijing group were injected with 4 mL/kg Xuebijing (once every 12 hours for 3 days), and the rats in the others two groups were injected with the same volume of saline, the image analytical system were used to detect the pathological change of intestinal tract mucosa harriers and the expression of macrophage antibody in three groups. All the data were analyzed by rank-sum test and variance analysis(F test). Results Almost all the mucous mem-brahe of small intestine in sham groups were normal. The mucous membrane lesions of small intestine developed in sepsis and Xuebijing groups after 12,24,48,72 hours, and the lesion was severer in sepsis group than that in the Xuebijing group (H=19.732, P<0.01). There were no significant differences on the expression of macrophage antibody in mucous membrane of small intestine between three groups at 3 hours. But at 12, 24, 48 and 72 hours, the expression of macmphage antibody of sepsis and Xnebijing groups increased with time (F=560.13, P< 0.05). Conclusions At the early period of sepsis, intestinal tract mucosa barriers develops varying degrees of damage, and Xnebijing can partly protect intestinal tract mucosa barriers.

Objective: To study the effects of CTGF on the periodontal tissue remolding during orthodontic tooth movement. Methods: A mouse model of orthodontic tooth movement was established. The CTGF and NS were injected into the periodontal tissue of the first molar. HE staining, immunohistochemical staining and automatic image analysis system were used to detect the changes of periodontal tissue and the expression of VEGF. Results: The periodontal tissue remolding accompanied the over expression of VEGF during the orthodontic tooth movement. At day 7, the remolding was most active and the expression of VEGF was the highest. CTGF injection induced acceleration of periodontal remolding and up-regulating the expression of VEGF during orthodontic tooth movement, especially at day 7 and day 15 after the orthodontic force were applied. Conclusion: In the mouse model of orthodontic tooth movement, periodontal CTGF injection induces over expression of VEGF and accelerates the periodontal remodeling during orthodontic tooth movement.
