Background and purpose:Traditional Chinese medicine with notable effect and little adverse reaction is increasingly concerned about the medical profession because of its great potential and advantage in treating pancreatic carcinoma. In this experiment, we studied the effects of oridonin on apoptosis and cytoskeletal protein F-actin in human pancreatic carcinoma SW1990 cells. Methods:SW1990 cells in culture medium were treated with different concentrations of oridonin. The inhibitory rate of the cells was measured by MTT assay. Morphology of cell apoptosis was observed by DAPI stain and cell apoptotic rate was detected by lfow cytometry (FCM). The morphological changes of F-actin were observed by laser confocal microscopy. Results:The growth of human pancreatic carcinoma SW1990 cells was signiifcantly inhibited by oridonin. Apoptosis morphological changes including condensation of chromatin and nuclear fragmentation were observed clearly by DAPI stain. The early apoptotic rate of SW1990 cells treated with 25, 50μmol/L oridonin was signiifcantly higher than that of the control group (3.78±0.46, 9.51±0.63 vs 0.73±0.06, P<0.05), and the late apoptotic rate and cell necrosis rate were also signiifcantly higher than that of the control group (14.40±1.78, 20.53±2.54 vs 4.16±0.31, P<0.05). F-actin was showed from polymerization to depolymerization after oridonin treatment. Conclusion:Oridonin can obviously inhibit the proliferation and induce apoptosis of SW1990 cells. The mechanisms may involve the depolymerization of F-actin after treatment with oridonin.

Objective To evaluate the safety and efficacy of endoscopic ultrasonography(EUS) guided ethanol ablation in patients with insulinoma. Methods The data of 10 patients with insulinoma trea-ted at the First Affiliated Hospital of Guangxi Medical University from December 2013 to January 2015 were prospectively analyzed. Results The patients were given EUS-guided ethanol ablation with dose of 0. 10 to 2. 00 ml(average 0. 70 ± 0. 62 ml)in pancreatic lesions for 15 times. No complications were observed dur-ing and after the procedure. The blood glucose improved after the procedure[4. 8(3. 9-5. 5)mmol/ L VS 2. 4 (1. 9-2. 5)mmol/ L,P < 0. 05]and the serum insulin level significantly decreased[83. 7(40. 1-143. 5) pmol/ L VS 177. 3(66. 5-200. 6)pmol/ L,P<0. 05]. The average hospital stay was(4. 3±1. 5)days. The patients were followed up for 6-12 months. EUS indicated that the echo of pancreatic lesions changed from high to low. CE-EUS revealed low enhancement and lack of blood supply. Conclusion EUS-guided ethanol ablation may become a promising minimally invasive treatment for insulinoma because of its safety,efficacy and low price.

Splenic flexure volvulus is the least common form of colonic volvulus. Preoperative radiological diagnosis is usually made presumptively, based on plain radiographs and/or barium contrast enema study in patients presenting with acute large bowel obstruction. We report a case in which multidetector computer tomography (CT) findings were diagnostic of this condition, thus highlighting the usefulness of multiplanar reformatting.

Objective To explore the differences of bone age of radius,ulna,metacarpophalangeal and carpal bones in children with different physiques.Methods Radiographs of children's wrists aged between 4 and 12 years were collected.The bone age of radius,ulna,metacarpophalangeal,and carpal bones were assessed using the Chinese Children's Bone Age Score,and the difference between the two bone ages(the former minus the latter)was recorded.According to gender,age,and physical grouping,the physical group was divided into normal and abnormal groups.The abnormal group was further divided into thin,overweight,and obese groups.A comparative analysis was conducted to determine the differences in bone age between normal and abnormal groups for both males and females at all ages.Results A total of 3 028 children were included,and the differences between the two bone age results for normal boys aged 7-12 years and normal girls aged 5-12 years were not statistically significant(P＞0.05).In boys,there was no significant difference in bone age between the normal group and the thin group(P＞0.05),the difference in bone age between the normal and thin groups at the age of 5-6 years was greater than that between the overweight and obese groups,and the difference was statistically significant(P＜0.05),the difference in bone age between the normal group at 11-12 years and the thin group at 11 years was smaller than that between the overweight and obese groups(P＜0.05).The difference in bone age was smaller in the normal group than in the thin group at 6 years of age for girls(P＜0.05),and larger in the thin group than in the overweight and obese groups at 5 to 6 years old(P＜0.05).Conclusion The difference in bone age between the TW-C RUS series and TW-C C series bone age values is influenced by the child's gender,physique,and age.The difference in bone age between the majority of normal children and the thin group is not statistically significant,but differed from the overweight and obese groups at some ages,most are the overweight and obese boys.
