Objective To investigate etiology and clinical features of acute pancreatitis (AP) in young patients. Methods In total, 423 patients with AP admitted to Renmin Hospital of Wuhan University, Wuhan, Hubei province during January 2006 to December 2009 were retrospectively analyzed, 55 cases aged 34 years or less as young group and another 55 cases aged more than 34 years as middle- and elderly-age group. Their etiology, clinical features and illness scores based on some standard criteria were assessed. Results Proportion of varied etiologies of AP in young group was different from that in middle- and elderly-age one (x2 = 17. 107, P = 0. 009) , mainly as biliary and idiopathic pancreatitis in young group and as biliary and alcoholic pancreatitis in middle- and elderly-age one. Incidence of diet-related and idiopathic pancreatitis were higher in young group than that in middle- and elderly-age one ( x2 =4. 853, P = 0. 028 and x2=4. 274, P = 0. 039 ). Scores of the acute physiology and chronic health evaluation II ( APACHE II ) , Ranson criteria and the bedside index for severity in acute pancreatitis ( BISAP) were all lower in young group than those in middle- and elderly-age one (t = 5. 381 , P = 0. 000; t = 4. 388 , P = 0. 000 and t=3. 083, P = 0. 003 ) . There was no statistically significant difference in scores of computed tomography severity index ( CTSI) between young group and middle- and elderly-age one (t = ±0. 750, P > 0. 05 ) . Recurrence rate of AP was lower in young group than that in middle- and elderly-age one ( x2 =4. 251, P = 0. 039). Cholecystitis was more complicated in young group, pregnancy was more complicated in young group (x2 =4. 151 , P =0. 042) , and elevated blood glucose was more complicated in middle- and elderly-age one (x2 = 13. 285 , P = 0. 000 ) . Conclusions Etiology of AP varies in young patients with more dietary factors, occurrence of systemic complications and risks for death are lower in young group than those in middle- and elderly-age one, and there was no statistically significant difference in local complications and severity of illness between the two groups.

AlM:To determine the changes of regional macular retinal thickness ( RT ) with spectral domain optical coherence tomography ( SD-OCT ) after successful pars plana vitrectomy ( PPV ) surgery with inner limiting membrane ( lLM ) peeling in patients with idiopathic macular hole.
METHODS:A non-randomized retrospective case study on 17 patients ( 17 eyes ) who were hospitalized between March 1, 2011 and June 30, 2013. All 17 eyes had been diagnosed with idiopathic macular hole and thereafter underwent 25G-PPV surgeries performed by the same surgeon with lLM peeling and short - term gas tamponade. ln the 6mo-plus follow-up after surgery, these eyes were found to have successful closure in the macular hole. The macular RT of the nine areas in the Early Treatment Diabetic Retinopathy Study was measured by SD-OCT. All patients were applied by SD-OCT with linear scan of the macular. At least four examinations on the operated eye were conducted in contrast to the other normal eye: before the surgery, 3~5wk after the surgery (stage A), 2~3mo after the surgery (stage B), and >6mo after the surgery (stage C).
RESULTS:ln stage A, the macular RT of operated eyes in the areas of C, lS, ll, lN, OS, Ol, ON (263. 00±39. 48, 313. 92±18. 35, 311. 00±18. 02, 335. 67±19. 91, 280. 83±33. 74, 269. 92 ± 23. 32, 307. 00 ± 28. 40 ) were significantly thicker than the corresponding areas of the normal fellow eyes (220. 51 ± 23. 94, 292. 08 ± 21. 93, 282. 50 ± 20. 30, 288. 33 ± 20. 76, 251. 25±17. 60, 247. 75±21. 48, 265. 17±24. 76ü m) (P<0. 01) with the exception of the lT (291. 58±18. 97, 280. 33± 20.82üm) and OT (250.83±21.21, 242.08±24.02üm) (P>0. 01). ln Stage B, the macular RT in the areas of ll, lN, OS (335.67±19.20,319.75±19.20, 273.50±16.89üm) were significantly thicker than the corresponding areas of the normal fellow eyes (286. 33±20. 46, 293. 42±17. 64, 252. 50± 16.32üm) (P<0. 01). However, the macular RT of the operated eyes in the areas of C, lS, lT, Ol and OT had no statistically significant difference compared with the corresponding areas of the normal fellow eyes (P> 0. 01). ln Stage C, the macular RT of operated eyes with the areas of lN (321. 17 ± 19. 71ü m) were significantly thicker than the corresponding areas of the normal fellow eyes (296.25±19.57üm) (P<0.01). Meanwhile the other areas of the operated eyes were not significantly different from the normal fellow eyes (P>0. 01). Moreover, the macular RT of operated eyes in the areas of ON, lT (307. 00±28. 40, 291. 58 ± 18. 97ü m ) in stage A significantly decreased compared to that of the corresponding areas in stage C (276. 08±32. 39, 278. 75±10. 19ü m) (P<0. 01).
CONCLUSlON: SD-OCT is a convenient tool for the observation of macular regional changes after macular hole surgery. Macular RT had persistent changes after vitrectomy on eyes with macular hole by SD-OCT. lLM peeling may have caused microstructural changes in wide areas of the macular region after PPV surgery. More support and evidence were provided to the further study of the long - term observation for the structural and function of macular after macular hole surgery.

Objective To observe the effect of PaCO_2 modulating during operation on post-operative cognitive function of patients undergoing off-pump coronary artery(OPCAB). Methods Thirty patients undergoing OPCAB were randomly divided into traditional group (G_ 1 , n=15) and modulated group (G_ 2 , n=15). During operation, PaCO_ 2 in G_ 1 maintained 35 mmHg to 39 mmHg with relatively fixed ventilation parameters setting, and PaCO_ 2 in G_ 2 ranged from 40 mmHg to 45 mmHg by adjusting ventilation parameters. Continuous cardiac output index (CCI), SvO_ 2 , regional cerebral O_ 2 saturation (rSO_ 2 ) and PaCO_ 2 were recorded before distal anastomosis(T_ 1 ), at 5 min of the first distal vessel anastomosis(T_ 2 ), second distal vessel anastomosis(T_ 3 ) and third distal vessel anastomosis(T_ 4 ), and 20 min after the completion of coronary artery anastomoses. HDS-R and ADL were used to examine the patients' cognitive function. Results There were no significant differences in pre- and post-operative HDS-R and pre-operative ADL scores between groups. The score of post-HDS-R in G_ 1 was obviously lower than that of pre-HDS-R (P

Objective To study the related factors of recurrence after myomectomy. Methods The clinical data of 441 cases with myomectomy were collected. The age at the time of operation, body mass index(BMI), preoperative parity, and the location, size and number of myomas were recorded, and the postoperative recurrence rate was calculated. Univariate and multivariate analysis were performed for possible factors related to recurrence. Results The average time of follow-up was(37.79?18.64) months. Recurrence was found in 125 cases, and 5-year cumulative rate of recurrence was 38.9%. The age at the time of operation, BMI, number of myomas and preoperative parity were related factors of recurrence(P

To assess the impact of the operational simulation training system on the cultivation of ophthalmic students.
●METHODS: Four hundred and eighty ophthalmic students in China Medical University from 2009 to 2011 were chosen as objects and divided into two groups at random. The students in the experimental group used operation simulation training system combined with traditional teaching methods, while the students in the control group only used traditional teaching methods. We examined the operation skills and the confidence of all the students half a year later.
●RESULTS: The improvement of the operation skills during the suture technique examination, and the confidence for operation technology were significantly different in two groups. The basic skills of the students in the examination groups improved apparently during the operational simulation training and they were full of confidence to their operational technique.
●CONCLUSlON: The operational simulation training is useful for promoting the clinical ability for ophthalmic students and should be widely popularized.
