Objective To study the similarities and differences of personality in patients with body-dysmorphic disorder(BDD),obsessive-compulsive disorder(OCD) and ordinary person.As well as to provide information for clinical therapy. Methods All BDD patients( n =29),OCD controls( n =30) and normal controls( n =30) completed Self Rating Scale of Body Image (SRSBI) and Minnesota Multiphasic Personality Inventory (MMPI). Results Ten clinical scales score of MMPI in BDD were found significant higher than normal controls which including hypochondriasis,depression,hysteria, psychopathic deviate, masculinity-femininity, paranoia,psychasthenia,schizophrenia,and social introversion.Four clinical scales[(68.18±8.70),(65.44±8.73),(61.39±9.37),(60.70±12.88)] were significant higher than OCD controls[(61.09±13.29),(58.82±10.26 ),(56.23±9.58),(50.03±12.63)] which including psychopathic deviate,psychasthenia,schiaophrenia and social introversion( P ＜0.05). But hysteria scale was significant lower than OCD controls( P ＜0.01). Conclusion BDD patients have abnormal personality which is more significant than OCD patients. Significant abnormal personality are likely the psychopathology of BDD from which the clinic symptom produced.

Objective:To investigate the feasibility,moderate-and short-term efficacies of laparoscopic surgery in the resection of the gastric gastrointestinal stromal tumors(GIST)with the tumor diameter more than 5 cm.Methods:The clinicopathological data of 26 gastric GIST patients with the diameter more than 5 cm underwent laparoscopic complete resection were retrospectively analyzed.The postoperative recovery,complications and moderate-and short-term prognosis of the patients were observed.Results:All the patients underwent laparoscopic surgery resection without open operation.According to the location and growth types of tumors,the total gastrectomy was performed in 1 case,the approximal gastrectomy was performed in 2 cases,the distal gastrectomy was performed in 2 cases,and the gastric local resection was performed in the rest 20 cases.The mean diameter of tumors was (5.94±1.28) cm,the mean operational time was (84.23±27.02) min,and the mean blood loss was (72.38±34.24) mL.The postoperative recovery time of bowel function was (2.77±0.65)d and the mean length of postoperative hospitalization time was (7.04±2.24) d.There was 1 case of intraperitoneal hemorrhage and 1 case of anastomotic stenosis;they recovered after conservative therapy.The postoperative pathology results(according to the modified NIH standard) indicated the number of moderate-risk patients was 18(69.23%),and the number of high-risk patients was 8(30.77%).A total of 12 cases accepted the adjuvant therapy with imatinib.There was 1 case of hepatic multimetastasis,and there was no local recurrence or death in the other patients.Conclusion:The moderate-and short-term efficacies of laparoscopic surgery in the gastric GIST patients with the tumor diameter more than 5 cm is safe and feasible.

AIM: To investigate the role of p38 protein kinase in the activation of rat alveolar macrophages(AMs) induced by lipopolysaccharide(LPS). METHODS: Nuclear protein was extracted, p38 protein kinase in nuclear extracts was analyzed by Western blot. The concentrations of TNF-? and IL-8 in supernatant were measured by radioimmunoassay. RESULTS: The concentrations of TNF-?, IL-8 in supernatant and p38 protein kinase in nuclear extracts were increased significantly induced by LPS and blocked by SB203580, a selective inhibitor of p38 protein kinase. CONCLUSION: The inductoin of TNF-? and IL-8 in alveolar macrophages by LPS may be mediated through the activation of p38 protein kinase.

Objective:To investigate the efficacy and safety of three-dimensional navigation template assisted osteotomy for fracture malunion of lateral condyle of humerus in children.Methods:Eighteen children with ma-lunion of fracture of lateral condyle of humerus were treated in Southern Medical University Third Affiliated Hospital from August 2012 to December 2019 and analyzed retrospectively.Among them, 12 cases were treated with routine ope-ration: according to CT reconstruction and empirical osteotomy during the operation, the location of deformity was analyzed.Six cases were treated with navigation template assisted osteotomy: according to the CT data of bilateral elbow joints, a three-dimensional bone model was established, and the coronal and sagittal deformities of the distal humerus were evaluated by comparing the images of the distal humerus of the affected side with the distal humerus of the healthy side, so as to determine the best plane of osteotomy and the target position of reduction.The preoperative simulation was carried out on the computer, and the osteotomy navigation template and reduction navigation template were designed.The navigation template was printed out with a 3D printer.During the operation, the osteotomy was corrected with the assistance of navigation template, and the broken end of osteotomy was fixed with hollow screw and fixed with 80 degree flexion plaster.The X-ray films of the two groups were reexamined regularly after operation.The amount of intraoperative blood loss, operation time, incidence of postoperative complications (necrosis of humeral head and trochlea, delayed ulnar nerve paralysis, and bone nonunion) and the recovery of flexion and the extension function of elbow joint were observed in the 2 groups.Results:The elbow joint activity of all children basically returned to normal, the orthopedic site of osteotomy achieved bony healing, and the orthopedic effects were satisfactory.All the 18 cases were followed up for 6-24 months (mean 15 months). According to the postoperative Dhillon score, the navigation template group was excellent in 1 case and better in 5 cases, while in the routine group, 11 cases were batter and 1 case was fair.There were no significant differences in Dhillon score between the 2 groups after operation ( P>0.05). There were no significant differences in the range of the motion of elbow joint between the 2 groups ( P>0.05). In the comparison of operation time and intraoperative blood loss, the navigation template group [(200.0±24.2) min, (85.0±10.9) mL]was better than the routine group[(232.0±20.1) min, (139.1±18.3) mL](all P<0.001). Conclusions:The application of three-dimensional humerus reconstruction and mirror image contrast to evaluate the distal humerus deformity of the affected side, and the design of osteotomy and reduction navigation template auxiliary operation can restore the normal anatomical structure of elbow joint to the greatest extent.Accurate correction, and the function of elbow joint recover well after operation, which optimizes the operation procedure, improves the safety and effectiveness of the operation.
