Objective To evaluate the test-retest reliability of the ballistic push-up(BPU)test and establish predictive models for upper-limb strength and explosive power in young males.Methods A total of 71 male college students performed assessments of upper-limb bench press 1 repetition maximum(1RM)strength,bench press explosive power,and two BPU tests with a 48-hour interval.BPU test data were recorded using a three-dimensional(3D)force platform and motion capture system to calculate concentric metrics such as peak force(PF)and mean velocity(MV).The intraclass correlation coefficient(ICC)was used to examine the retest reliability of the BPU test.The Pearson correlation coefficient was used to evaluate the correlation of the BPU metrics with upper-limb strength and explosive power.Predictive models for upper-limb strength and explosive power were created using stepwise regression analysis.Results BPU metrics showed a good test-retest reliability(ICC=0.764-0.935).PF and MV,along with body weight(BW),were effective predictors of bench press 1RM in young males:bench press 1RM=0.129PF-16.772[R2=0.790,standard error of the estimate(SEE)=8.17 kg];bench press 1RM=1.511BW+87.15 MV-110.136(R2=0.767,SEE=8.60 kg).PF and BW were also predictors of bench press explosive power:bench press explosive power=2.755BW+0.287PF-17.351(R2=0.620,SEE=46.1 W).Conclusions The BPU test demonstrates a good test-retest reliability,and PF and MV from the BPU test can be used to predict upper-limb strength and explosive power in young males.

Medical staff can develop scientific and effective follow-up management based on patients and clinical conditions to improve the quality of care for ICU transferred patients.

Palliative care is the final link in the whole lifecycle health management and is an important part of promoting a healthy China. In order to further improve service efficiency and the quality of end-of-life care, Shanghai Jiading Yingyuan Hospital has constructed a new interdisciplinary team collaboration model for palliative care from the perspective of integrated medical theory, and applied this model to clinical practice. By elaborating on the theory of team integration, member composition and division of labor, implementation process and preliminary effects, this study aims to provide a theoretical basis and reference for other regions to carry out the integration path and collaborative model of interdisciplinary services in palliative care.

Objective:To construct follow-up index system of ICU patients with acute kidney injury based on the Omaha nursing outcome classification system, and to provide a reference for the clinical care quality and the follow-up work of ICU patients after discharge.Methods:Based on the Omaha nursing outcome classification system, the Delphi method was used to establish the content of the follow-up index system for ICU patients with acute kidney injury, and determine the weight of all levels of indicators.Results:After two rounds of expert consultation, questionnaire response rates were 95.00%and 100.00%, expert authority coefficients were 0.861 and 0.892 (both P<0.01), coordination coefficients ranged from 0.296 to 0.667 and 0.240 to 0.804, the difference were statistically significant ( χ2 values were 60.77-288.17, and P<0.01). The final index system consisted of 4 first-level indicators, 16 second-level indicators, and 52 third-level indicators. The analytic hierarchy process was used to determine the weights of all indexes, and the consistency test (consistency ratio<0.1) was performed. Conclusions:The follow-up index system of ICU patients with acute kidney injury was constructed to provide a reference for the clinical care quality and the follow-up work of ICU patients after discharge, and to provide a theoretical basis for the follow-up mode after ICU.

ObjectiveTo explore the classification, limb salvage strategy and treatmental results following resection of malignant bone tumors around the shoulder girdle. Methods28 patients with malignant bone tumors of the shoulder girdle underwent a limb-sparing resection according to Malawer's surgical classification system of shoulder girdle. Various limb-salvage procedures were performed for all patients. They were evaluated with survival, recrudesce, and metastasis. The function outcome was assesssed with Enneking Function Evaluation System. Results25 patients were followed-up with a mean time of 54 months (ranged 9～96 months)．6 patients recrudesced, 11 patients died．According to Enneking Function Evaluation System, the mean score of the upper extremity was 23 in reimplantation of tumor-bearing bone after alcohol devitalization group, 24 in osteoarticular allograft group, 24 in free periosteum vascularized clavicle group, 26 point in endoprosthesis group, 25 in the total scapulectomies and the head of humerus slinging group, 28.5 in the partial scapulectomies group respectively. ConclusionThe malignant bone tumors around the shoulder girdle can be resected completely. There were a variety of limb-salvage procedures following tumors resection, with which hand function can be preserved in the majority of patients with relieved pain and good function shoulder.

Objective To investigate the venous drainage of lesser saphenous aural neurov enofasciocutaneous distally based flap through fluorescence tracing technique and discuss the pattern of venous drainage.Methods Venous blood for 0.1 ml was collected from every rabbit ear vein of 20 rabbits respectively for separation of the erythrocytes and labeling with FITC.The lesser saphenous sural neurovenofasciocutaneous distally based flaps were successfully established in hind limbs of 20 rabbits that were then allocated into four groups according to different inspection time points at 30 minutes ( Croup A) ,24 hours (Group B) ,72 hours (Group C) and 7 days (Group D) after operation.The labeled erythrocytes (5 μl) were injected into the flaps via lesser saphenous vein (in Groups A and B)or hypoderma (in Groups C and D).Then,the flaps were removed five seconds (in Groups A and B) or 10 seconds (in Groups C and D) after injection,immediately frozen and sectioned (5-7 μm in thickness) for microscopic analysis of fluorescent distribution in the pedicle.Results FITC-labeled red blood cells showed steady green fluorescence under inversion fluorescence microscope.Fluorescence was mainly distributed in the wall of lesser saphenous vein and peripheral vessels,as well as inner and outer membrane of perforator artery.There was only faint fluorescence around sural nerve in Groups B,C and D.HE staining showed that the lumina of lesser saphenous vein in Groups C and D were fully filled with thrombosis.Conclusions Vein of the lesser saphenous sural neurovenofasciocutaneous distally based flaps is refluxed mainly through wall of lesser saphenous vein and peripheral vessels as well as through inner and outer membrane of perforator artery in the pedicle.Thrombosis occurs in the lumina of lesser saphenous but there is no venous blood reflux through the valve of lesser saphenous vein.

Objective To evaluate the stability of the pelvic ring reconstruction using fibular autograft for periacetabular tumor type Ⅱ resection. Methods 6 adult cadaveric specimens were tested. The periacetabular tumor resection models were established according to Ennecking's type Ⅱ resection. The resected pelvic rings were reconstructed with double-fibular graft fixed by four internal fixation techniques including plates, pedicle-rods (PR), lateral-rods (LR) or sacral-iliac rods (SIR). Axial loading from the proximal L3 vertebral body was applied by MTS load cell in the gradient of 0～500 N in the double feet standing state. Images in front view were obtained using CCD camera. Based on Image J software, displacement of the first sacral vertebrae （S1） of the reconstructed pelvis and intact pelvis were calculated using digital maker tracing method with center-of-mass algorithm. Results The rotational movements and vertical displacement of S1 around the normal side femoral head of the reconstructed pelvis in coronary plane were found in simulated bilateral leg standing position. The average vertical load-displacement and load-angular rotation curve of S1 in coronary plane were approximately linear behavior under the vertical load 500 N. The average vertical displacement and angle of S1 in coronary plane had not overacted. The stability of axial direction and rotation had not changed significantly when reconstructed by LR or Plates compared with the intact pelvis, but the SIR did. Conclusion Plates and LR fixation were more stabile for periacetabular tumor type Ⅱ resection.
