ABSTRACT
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.
ABSTRACT
One hundred and eighty three patients with esophageal cancer admitted from September 2015 to September 2016 were randomly divided into two groups:91 patients received clinician-involving pre-discharge and postoperative follow-up health education (study group) and 92 patients received traditional health education (control group).The quality of life and the compliance rate of comprehensive treatment within 3 months after discharge were evaluated and compared between two groups.The overall scores of quality of life in study group was significantly better than those of the control group (P＜ 0.05),and the compliance rate of comprehensive treatment after discharge in study group was significantly higher than that of control group [82.4％(75/91) vs.67.4％(62/92),x2=5.49,P=0.02].It is suggested that clinician participating in the pre-discharge and follow-up health education can improve the quality of life of patients,and improve the compliance of comprehensive treatment after discharge.

Additionally, Dmax of the intestine (21.17 ± 2.90 vs 20.63 ± 3.13), D10cc of the stomach (12.78 ± 2.57 vs 13.11 ± 2.43), D5ccof the duodenum (11.01 ± 3.45 vs 11.50 ± 3.25), D10ccof the duodenum (9.30 ± 3.31 vs 9.78 ± 3.07) and D0.35ccof the spinal cord (6.09 ± 0.98 vs 6.59 ± 0.92) were all significantly decreased (P<0.05). No significant differences were found on other parameters. Conclusions Better dose distributions are accessible by one-step optimization with 7 shells in CyberKnife treatment plans for pancreatic cancer.
ABSTRACT
BACKGROUND: It remains poorly understood whether anterior column quadrilateral wing plate exists to solve intraoperative multiple plastic and quadrilateral in vivo shift for treating acetabular anterior column and acetabular quadrilateral body fractures.OBJECTIVE: To figure out the promising application on measurement of anatomical character parameters when designing acetabular anterior column and acetabular quadrilateral body using Mimics software. METHODS: 60 pelvic CT scan data were collected and three-dimensionally reconstructed by Mimics software. The following anatomical character parameters were measured, including the angle between plane of arcuate line of true pelvis and plane of quadrilateral surface, the four boundary lines of quadrilateral body, and the thickness of substance of bone in quadrilateral region. The projection curve on quadrilateral surface of acetabular margin and dangerous zone for screw placement were both drew. Above all, the study attempted to find out the proper safe entry point of quadrilateral screw and to measure their leaning inside angles.RESULTS AND CONCLUSION: (1) The angle between plane of arcuate line of true pelvis and plane of quadrilateral surface was not significantly different between males and females. (2) The minimum thickness of quadrilateral body in males was larger than that in females. (3) The maximum leaning angle flapper plate screw P1 and P2 for quadrilateral body was significantly smaller in males than in females, but that of screw P3 was not significantly different between males and females. (4) The application of Mimics software made it easier, more intuitive and more practical for the design or development of new plate for acetabular anterior column and acetabular quadrilateral body. The common points and difference between acetabular anterior column and acetabular quadrilateral body could be specifically described by the new anatomical character parameters, which are defined by bone surface features of pelvis.

ABSTRACT
Objective To investigate the effect of all-in-one nursing intervention on esophageal carcinoma patients with bad emotion and immune function. Methods From the October, 2012 to the October, 2013, 102 patients with radical operation of esophageal carcinoma were divided into all-in-one nursing intervention group (research group, 52cases) and routine nursing group (control group, 50 cases) according to the random number table method.Two groups of patients were evaluated before and after operation of anxiety and depression emotion scores, with the Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) .At the same time, two groups of patients were detected the stress and immune index before and after the operation. Results Before operation, two groups of patients with anxiety, depression, stress reaction and immune index were not significantly different (P>0.05).After operation, the study group patients with anxiety and depression scores were significantly lower than those in the control group [(34.6+6.7) points vs. (44.8+7.5) points, (33.7+6.9) points vs. (40.6+7.3) points], the difference was statistically significant (t values were 7.234, 4.902, P<0.05). Eighth days after operation, patients in the control group FBG, CRP and Cor levels were significantly higher in the study group [(6.98±1.12)mmol/L vs.(6.09±0.85)mmol/L,(18.11±5.93) mg/L vs.(9.24±3.22)mg/L,(293.98±69.09)nmol/L vs.(221.97±67.94)nmol/L],the difference was statistically significant (t values were 4.532, 9.336, 5.307, P<0.05). Eighth days after operation, two groups of patients with IgA, IgM were higher than first days after operation [(2.41±0.46)g/L vs.(1.89±0.56)g/L,(2.51±0.58) g/L vs.(1.35±0.67)g/L and (2.36±0.53)g/L vs.(1.82±0.46)g/L, (2.34±0.62)g/L vs. (1.37±0.64) g/L], the difference was statistically significant (t values were 5.174, 9.439, 5.549, 7.850, P<0.05).The total number of patients blood lymphocytes (LYM) and cytokines (CD3, CD4, CD8, CD4/CD8) were significantly higher than the control group [(2.87±0.65)×109/L vs.(1.98±0.58)×109/L, 0.62±0.10 vs. 0.57±0.07, 0.41±0.08 vs. 0.35 ±0.08, 0.24 ±0.04 vs. 0.26 ±0.05, 2.06 ±0.44 vs. 1.65 ±0.46], the difference was statistically significant (t values were 7.286, 2.915, 6.942, 2.225, 4.601, P<0.05).

ABSTRACT
BACKGROUND:Thoracolumbar fracture becomes more in the clinic. The fixation manner of thoracolumbar fracture is controversial. Injured vertebra pedicle screw fixation or traditional cross-segment pedicle screw fixation are controversial and lack the support of evidence-based medicine. OBJECTIVE: To evaluate the outcomes of injured vertebra pedicle screw and cross-segment pedicle screw fixation for thoracolumbar fractures. METHODS: According to Cochrane system evaluation, the folowing databases were retrieved: National Library of Medicine database, China National Knowledge Infrastructure, Wanfang database and VIP database. Conference proceedings were searched by hand. The retrieval time ranged from 2005 to March 2015. Randomized controled trials were colected. Meta-analysis was performed by using Cochrane Colaboration Revman 4.2. RESULTS AND CONCLUSION: By screening, a total of 14 clinical controled trials were selected, including 956 patients. Meta-analysis results showed that postoperative Cobb angle was improved significantly in the vertebral pedicle screw group than in the cross-segment pedicle screw fixation group (OR=-2.72, 95%CI:-3.08--2.35,P < 0.01). Correction rate of the vertebral height was higher in the vertebral pedicle screw group than in the cross-segment pedicle screw fixation group (OR=7.45, 95%CI:6.94-7.97,P < 0.01). The failure rate was lower in the vertebral pedicle screw group than in the cross-segment pedicle screw fixation group (OR=0.12, 95%CI: 0.05- 0.27,P < 0.01). Results verify that postoperative Cobb angle improved significantly after the injured vertebrae pedicle screw and cross-segment pedicle screw fixation for thoracolumbar fractures. The height was obviously corrected and fewer complications were caused such as implant failure. The fixation effect was good.
ABSTRACT
Objective To systematically compare the operative and non-operative treatments of acute injury to the lateral ankle ligaments in terms of efficacy and complications.Methods The databases of MEDLINE (From January 1966 to October 2011 ),EMBASE (From January 1988 to October 2011 ),CBMdisc (From January 1978 to October 2011) and CNKI (From January 1980 to October 2011 ) were researched for eligible randomized-controlled trials (RCTs),controlled clinical trials,quasi randomized controlled trials and cohort study which compared operative and non-operative treatments for acute injury to the lateral ankle ligaments.The methodological quality of the eligible studies collected was evaluated.The data of the studies included were extracted for a Meta analysis to compare the motional recovery,functional stability,re-injury,residual pain and post-treatment complications of the ankle between operative and non-operative treatments.RevMan 5.0 software was used for statistical analysis.Results In all the eligible 13 studies included,713 patients were treated operatively and 817 patients non-operatively.The functional stability of the ankle was significantly better in the operative treatment group than in the non-operative treatment group [ OR =0.72,95％ CI,(0.52,0.99),P ＜ 0.05].The incidence of ankle arthrocleisis in the operative treatment group was significantly higher than in the non-operative treatment group [ OR =3.41,95％ CI (1.56,7.44),P =0.002].There were no statistical differences in the motional recovery [ OR =1.14,95％ CI (0.58,2.21),P＞ 0.05],incidence ofre-injury [OR=0.68,95％ CI (0.35,1.31),P＞0.05],residual pain [ OR =0.81,95％ CI(0.56,1.16),P＞ 0.05],or ankle dyskinesia [ OR =2.38,95％ CI (0.91,6.25),P＞ 0.05]between the 2 groups.The incidences,scar tenderness [01R=7.46,95％CI(1.32,42.08),P ＜0.05]and sensory nerve loss [OR=12.16,95％ CI(2.24,66.02),P ＜0.05]were significantly higher in the operative treatment group than in the non-operative treatment group.The total rate of complications was significantly higher in the operative treatment group than in the non-operative treatment group [0R=6.20,95％ CI (2.67,14.41),P ＜0.05].Conclusions Compared with non-operative treatments,operative treatments for acute injury to the lateral ankle ligaments can significantly improve the functional stability of the ankle,but make no significant differences in the motional restoration,re-injury or the residual pain of the ankle.In addition,operative treatments may increase the risk of complications.
