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.

Objective To explore the sonographic characteristics and to evaluate its diagnostic value of hepatic lymphoma (HL). Methods The clinical data and abdominal sonographic ifndings of 18 consecutive patients with histological proven diagnosis of lymphoma with liver involvement were reviewed, including contrast-enhanced ultrasound (CEUS) images. Results The liver sonographic features of 18 HL were differentiated as three types including nodular, diffuse and mixed type. Nodular type showed well-deifned hypoecho lesions in 6 cases with penetrating vascular lfow signals in 2 cases and no vascular lfow signals in 6 cases by color Doppler imaging. In 3 cases by CEUS, all the hepatic focal nodulars showed variable arterial enhancement but wash-out in the portal venous and late phases. For diffuse type cases, hepatomegaly without nodule was showed in 11 cases. Vasular in liver showed normal in 8 cases and abnormal in 3 cases. For mixed type cases, hepatomegaly and multiple ill-deifned hypoechoic lesions with normal vascular in liver were showed in 1 case. Hepatosplenomegaly and abdominal lymphoadenopathies were identiifed in 11 cases. Conclusions The characteristics and the types of sonographic ifndings may be helpful in differentiating HL from other liver lesions.

Background Efficient and lowcost way to isolate keratocytes is helpful for research on cornea.Either relatively expensive or inefficient is the shortage of those means now applied,while raising the keratocytes through passage will change the phenotype of them quickly.Our aim is to approach the way getting keratocytes effectively utilizing modified two step enzymatic digestion by type I collagenase. Objective To evaluate the effect of isolating the bovine keratocytes utilizing two step enzymatic digestion and observe the morphological changes of the keratocytes during cultivation in vitro. Methods Keratocytes were isolated from bovine corneas using 0.5 mg/mL and 1 mg/mL type I collagenase digestion.The harvesting rate and viability rate of the primary keratocytes were evaluated.During the primary cultivation in vitro,the morphological changes of the keratocytes and their F-action distribution were observed.Results(1)The extracellular matrix of the bovine corneas were almost dissolved by the two step enzymatic digestion,followed the keratocytes completely isolated from the solid matrix.The amount of the harvested keratocytes from each cornea was(2.11±0.15)X106 on average while the viability rate was(91.69±3.73)% and the inoculation rate Was(81.20±1.25)%.(2)The primary keratocytes attached and spreaded out with dendritic and stellate morphology.After 3 days cultured,the branches of the keratocytes were contacting and formed networks.The F-actin detected by phalloidin binding showed a limited cortical localization. Conclusion (1)The method of two step enzymatic digestion can make the extracellular matrix of bovine cornea stroma completely degraded with the advantages in high efficiency of harvesting keratocytes and high cell viability and relatively simple manipulation. (2) The primary bovine keratocytes have dendritic morphology and with limited F-action distribute in cellular cortex.

Objective To investigate the trend of early neural development in premature infants. Methods At the age of 12 months and 24 months, Bayley Scales of Infant Development were used to assess the mental development index (MDI) and the psychomotor development index (PDI) in preterm (corrected age) and full-term infants. Results At 12 months, there was no significant difference in corrected age PDI scores among different gestational age groups (<32 , 32–33+6 and 34–36+6 weeks) (P=0.820). The actual age MDI and PDI scores of full-term infants and premature infants in 34~36+6 weeks group were significantly higher than those of premature infants in <32 and 32-33+6 weeks groups, and the PDI score of full-term infants was significantly higher than that of premature infants in 34-36+6 weeks group (P<0.05). There was no significant difference in actual age PDI scores among different birth weight groups (P=0.166). The actual age MDI and PDI of full-term infants and premature infants in birth weight≥2500 g group were significantly higher than those of premature infants in <1500 g, 1500~1999 g and 2000~2499 g groups (P<0.05). At 24 months, the actual age MDI scores of full-term infants were significantly higher than those of premature infants in different gestational age and birth weight groups (P<0.05). The actual age MDI curve of premature infants in birth weight <1500g group showed a downward trend, while the actual age PDI curve showed a significant upward trend. Conclusion The neurodevelopment of preterm infants at the corrected age of 12 and 24 months reaches the level of full-term infants.

AIM: To study the effects of Sodium Hyaluronate (HA) and Bion Tears on corneal thickness in adult myopic patients.METHODS: A total of 38 cases (76 eyes) were involved in this study. Three consecutive corneal measurements (the thinnest point of the cornea,THN) were evaluated before and half an hour after the instillation of one drop of HA in one eye and Bion Tears in the other at random with the Orbscan Corneal Topography System II (Orbscan,Inc,Salt Lake City,UT,USA,Version 3.00E).RESULTS: There were no significant between-group differences in baseline variable (t=0.264). Thirty minutes after the instillation of HA and Bion tears,THN were significantly increased by 5.57±7.00μm (t=4.906,P<0.01) and 7.89±7.64μm (t=6.369,P<0.01) respectively. However,there were no between-group differences in THN changes(t=1.381,P>0.05).Increase in the corneal thickness were found in 32 eyes (84%) and 33 eyes (87%) for the HA and Bion tears group,respectively.CONCLUSION: Artificial tears including HA and Bion Tears can significantly increase the corneal thickness in a short period of time. Corneal thickness can be used as one of the objective indices for evaluating the quality and therapeutic role of artificial tears.

Objective:To compare the patient-centered doctor-patient communication skills in anesthesiologists with different working experience and genders.Methods:The second and third year residents who had been trained as residents in the Department of Anesthesiology in our hospital from September 2017 and September 2018 and senior physicians who had worked for 10-15 yr in our hospital, were recruited to perform a preoperative interview in a standardized patient counter.Consultation and Relational Empathy (CARE) measure was used to assess the communication skills among senior physicians, residents, and anesthesiologists of different genders.The residents also took the objective structured clinical examination (OSCE) and theory examination.Results:Thirty-six residents and 20 senior physicians were included.There was no significant difference in the CARE measure score between residents and senior physicians and in the total CARE measure score between residents who received doctor-patient communication training at the stage of medical students and those who did not ( P>0.05). Compared with the residents in the second year, the listening ability score and decision-making ability score were significantly decreased ( P<0.05), and no significant change was found in the scores for the other items in the residents in the third year ( P>0.05). Compared with residents, the listening ability scores were significantly increased, and the caring ability scores were decreased ( P<0.05), and no significant change was found in the scores for the other items in senior physicians ( P>0.05). There was no difference in CARE measure scores between the male and female anesthesiologists.The resident′s CARE measure score was positively correlated with the annual OSCE score ( r=0.486, P<0.05), and there was no correlation between the resident′s CARE measure score and annual theoretical examination grade ( r=0.308, P>0.05). Conclusion:Senior anesthesiologists with more clinical experience are not superior to the junior residents in patient-centered communication skills, and the doctor-patient communication skills of residents are not related to their medical theoretical grade.Moreover, there is no significant difference between male and female anesthesiologists in terms of doctor-patient communication skills before surgery.Therefore, training of patient-centered doctor-patient communication skills should be strengthened at all levels of anesthesiologists.
