Objective To evaluate the impact of different ages, different gender, with or without exercise and different fracture sites on the nutritional status using mini nutritional assessment (MNA-SF) in hospitalized elderly fracture patients. Methods A total of 1 353 hospitalized elderly patients with fracture were included. The MNA-SF investigations were completed within 3 days after admission. The diet, body weight, physical activity, psychological trauma or stress, psychological problems, body mass index (BMI), calf circumference (CC), history of aerobic exercise and the fracture sites were recorded three days after admission. The nutritional status were evaluated including normal nutrition, risk of malnutrition and malnutritional status. The relationships of nutritional status were analyzed between different ages, different gender, with or without exercise, different fracture sites. Results There were significant differences in the incidence of normal nutrition, risk of malnutrition malnutrition and non-normal nutritional status between different ages, different gender, with or without exercise, femoral intertrochanteric fracture and upper limb fracture. There were also significant differences in the incidence of normal nutrition, risk of malnutrition and malnutrition between femoral neck fracture and upper limb fracture. Conclusion There is a higher incidence of non-normal nutritional status in patients older than 80 years, female, with no regular exercise and with femoral intertrochanteric fracture.

Objective Establishing a fingerprint method to identify the characteristic chemicals in the roots of Gentiana macrophylla and evaluate their quality.Methods RP-HPLC was developed for fingerprint analysis and determination of four ingredients in G macrophylla roots from different sources.LC-ESI-TOF-MS was employed to identify the chromatographic peaks of the fingerprint.Results Five common peaks were identified by comparing their retention time with reference secoiridoid glucosides.Eight major peaks in chromatographic fingerprint were analyzed by on-line LC-ESI-TOF-MS.Four secoiridoid glucosides were identified based on their MS data.Conclusion The method is specific and could be served for the quality identification and comprehensive evaluation of G macrophylla.

PURPOSE: To separate and evaluate the low frequency spontaneous fluctuation BOLD signals from the functional magnetic resonance imaging data using sensorimotor active task. MATERIALS AND METHODS: Twenty female archery players and twenty three control subjects were included in this study. Finger-tapping task consisted of three cycles of right finger tapping, with a subsequent 30 second rest. Blood oxygenation level-dependent (BOLD) data were collected using T2*-weighted echo planar imaging at a 3.0 T scanner. A 3-D FSPGR T1-weighted images were used for structural reference. Image processing and statistical analyses were performed using SPM5 for active finger-tapping task and GIFT program was used for statistical analyses of low frequency spontaneous fluctuation BOLD signal. RESULTS: Both groups showed the activation in the left primary motor cortex and supplemental motor area and in the right cerebellum for right finger-tapping task. ICA analysis using GIFT revealed independent components corresponding to contralateral and ipsilateral sensorimotor network and cognitive-related neural network. CONCLUSION: The current study demonstrated that the low frequency spontaneous fluctuation BOLD signals can be separated from the fMRI data using finger tapping paradigm. Also, it was found that these independent components correspond to spontaneous and coherent neural activity in the primary sensorimotor network and in the motor-cognitive network.

PURPOSE: Laparoscopic surgery is associated with lower surgical site infection (SSI) rates due to minimal skin incision and non-exposure of visceral organs. Most previous studies have analyzed the efficacy of prophylactic antibiotic use in open surgery. Here, we investigated the feasibility of total laparoscopic distal gastrectomy (TLDG) for gastric carcinoma without prophylactic antibiotic use.MATERIALS AND METHODS: Seventy-one patients who underwent TLDG without prophylactic antibiotic use were 1:1 propensity score matched with 393 patients who underwent TLDG with antibiotic prophylaxis. The short-term surgical outcomes, including SSI rates, were compared between the groups.RESULTS: After matching, 65 patients were selected in each group. The baseline clinicopathological characteristics were well balanced in the matched sample. In the matched group, there was no significant increase in postoperative morbidity in the non-prophylactic group compared with the prophylactic group (18.5% vs. 15.4%, P=0.640), and there were no grade 3≤ complications (1.4% vs. 0%, respectively; P=1.000). The SSI rates in the non-prophylactic and prophylactic groups were 3.1% and 1.5%, respectively (P=0.559). The time to gas passage, diet initiation, and mean hospital stay were not significantly different between the 2 groups. The SSI rate did not increase in the non-prophylactic group in the different subgroups based on different clinicopathological characteristics.CONCLUSIONS: Postoperative morbidity, including SSI rates, did not significantly increase in patients undergoing TLDG without prophylactic antibiotic use. A large prospective randomized trial is warranted to reappraise the efficacy of prophylactic antibiotic use in patients undergoing TLDG.

OBJECTIVE: To investigate the global functional reorganization of the brain following spinal cord injury with graph theory based approach by creating whole brain functional connectivity networks from resting state-functional magnetic resonance imaging (rs-fMRI), characterizing the reorganization of these networks using graph theoretical metrics and to compare these metrics between patients with spinal cord injury (SCI) and age-matched controls. METHODS: Twenty patients with incomplete cervical SCI (14 males, 6 females; age, 55+/-14.1 years) and 20 healthy subjects (10 males, 10 females; age, 52.9+/-13.6 years) participated in this study. To analyze the characteristics of the whole brain network constructed with functional connectivity using rs-fMRI, graph theoretical measures were calculated including clustering coefficient, characteristic path length, global efficiency and small-worldness. RESULTS: Clustering coefficient, global efficiency and small-worldness did not show any difference between controls and SCIs in all density ranges. The normalized characteristic path length to random network was higher in SCI patients than in controls and reached statistical significance at 12%-13% of density (p<0.05, uncorrected). CONCLUSION: The graph theoretical approach in brain functional connectivity might be helpful to reveal the information processing after SCI. These findings imply that patients with SCI can build on preserved competent brain control. Further analyses, such as topological rearrangement and hub region identification, will be needed for better understanding of neuroplasticity in patients with SCI.
