Objective To explore the consistency of time-of-flight (TOF) technology of PET/MRI and PET/CT for max standardized uptake value (SUVmax) of body malignant tumors.Methods A retrospective analysis of TOF-PET/CT and TOF-PET/MR imaging data about twenty patients with body malignant tumors was performed.Patients were divided into two groups (each n=10),including PET/CT first and sequentially PET/MR group and PET/MR first and sequentially PET/CT group.Bland-Altman figure was used to evaluate consistency of SUVmax of malignant lesions between TOF-PET/CT and TOF-PET/MR.Multi-way ANOVA was used to analysis effect of machine type and exam order on SUVmaxof malignant lesions in TOF-PET/CT and TOF-PET/MR.Results SUVmax of malignant lesions in TOF-PET/CT and TOF-PET/MR had good consistency in two groups (PET/CT first and sequentially PET/MR group:Mean difference was 3.06,95％CI was [-7.5,13.6];PET/MR first and sequentially PET/CT group:Mean difference was 3.0,95％CI was [-2.4,8.3]).SUVmax was not influenced by machine type (F=0.005,P=0.95),but exam order (F=46.00,P＜0.001).Conclusion PET/MR and PET/CT with TOF technology have comparative diagnostic value in SUVmaxof body malignant lesions.SUVmax of body malignant lesions increases in delay time,which is not related to machine type,but exam time.

OBJECTIVETo investigate the clinical effects of close reduction and minimally invasive percutaneous plate osteosynthesis in treating proximal humerus fractures in the aged.

METHODSFrom February 2012 to December 2013,39 patients with proximal humerus fractures were treated with minimally invasive percutaneous plate osteosynthesis (MIPPO group, 21 cases) and open reduction internal fixation (ORIF group, 18 cases). Including 17 males and 22 females in the study, and aged from 67 to 88 years old with an average of (71.8 ± 5.2) years old. In MIPPO group, there were 11 males and 10 females with an average age of (70.0 ± 5.3) years old;and in ORIF group, there were 10 males and 8 females with an average age of (72.0 ± 4.2) years old. Operation time, blood loss during operation, fracture healing time and postoperative complications were recorded. The functions of the shoulder joints were assessed according to Constant-Murley score at final follow-up.

RESULTSAll the patients were followed up from 11 to 27 months with an average of 18.1 months. The mean blood loss of the MIPPO group was (176.0 ± 57.4) ml,while the ORIF group was (356.0 ± 66.9) ml (t = 7.22,P = 0.01). The operation time of the MIPPO group was (47.4 ± 14.9) min, while the ORIF group was (92.7 ± 15.8) min (t = 0.79, P = 0.03). Fracture healing time in the MIPPO group and ORIF group was (17.6 ± 5.8), ( 21.7 ± 4.9) weeks, respectively (P < 0.05). The mean Constant-Murley score at final follow-up was 89.7 ± 14.5 in MIPPO group, and 81.8 ± 13.2 in ORIF group (P < 0.05).

CONCLUSIONMIPPO has advantages of little trauma, less blood loss, rapid recovery, less vascular damage and so on and can effectively treat the proximal humerus fracture in the aged.

[ ABSTRACT] AIM:To prove the purinergic signaling mechanism of the neuroprotective action of hydrogen sulfide by observing the effects of sodium hydrosulfide ( NaHS) , a donor of hydrogen sulfide, on the cell viability, intracellular Ca2+concentration ( [ Ca2+] i ) and the change of membrane permeability in the PC12 cells injured by adenosine triphos-phate ( ATP) .METHODS: PC12 cells in logarithmic growth phase were randomly divided into 4 groups.In control group, the cells were cultured without ATP treatment.In ATP group, the cells were treated with ATP after cultured for 24 h.In NaHS+ATP group, the cells were incubated with NaHS for 30 min before treated with ATP, and NaHS always exis-ted in the reaction system.In KN-62+ATP group, the cells were pretreated with KN-62 for 30 min, and the other treat-ments were as the same as those in NaHS+ATP group.The cell viability was assessed by MTT assay.The [ Ca2+] i was detected by Fura-2/AM staining.The membrane permeability was observed by staining with fluorescent dye YO-PRO-1. RESULTS:ATP at concentration of 0.3 mmol/L showed no injury effect on the cells.However, the cell viability was dropped gradually in a dose-dependent manner as the ATP at doses of 1, 3, 5 and 10 mmol/L.The decline of cell viability by ATP was obviously reversed by 200 μmol/L of NaHS in the PC12 cells (P<0.05), but exasperated by 800μmol/L of NaHS (P<0.05).At the same time, ATP evoked the increase in [Ca2+]i in a dose-dependent manner, which was inhib-ited by NaHS ( P<0.05) .Furthermore, the YO-PRO-1 uptake induced by ATP in a dose-dependent and time-dependent manner was also reduced by NaHS ( P<0.05) .CONCLUSION:Hydrogen sulfide has protective effect on the PC12 cells injured by ATP.The mechanism may be related to the reverse of the increased [ Ca2+] i and YO-PRO-1 uptake.

Objective To study the compatibility of TCM prescriptions of TCM practitioners of all dynasties of Alzheimer disease (AD). Methods Amnesia, forgetting, dementia, and idiot were set as search words to retrieve relevant literature in Encyclopadia of Traditional Chinese Medicine. Prescription information was screened and standardized to build database. Frequency analysis and association rules were used to mine TCM prescriptions and compatibility rules. Results Totally 449 AD related prescriptions were selected, involving 682 Chinese medicinal herbs. The individual herb with the highest frequency was Ginseng Radix Rhizoma (192);the herbal pair with the highest frequency was Ginseng Radix Rhizoma-Polyhalae Radix (182);the herbal combination with 3 Chinese medicinal herbs with the highest frequency was Poria with Hostwood-Ginseng Radix Rhizoma-Polyhalae Radix (79);the herbal combination with 4 Chinese medicinal herbs with the highest frequency was Polyhalae Radix-Ginseng Radix Rhizoma-Poria with Hostwood-Glycyrrhizae Radix et Rhizoma (37). The results of association rules showed that Ginseng Radix Rhizoma-Polyhalae Radix, Ginseng Radix Rhizoma-Glycyrrhizae Radix et Rhizoma, and Ginseng Radix Rhizoma-Poria with Hostwood were commonly used compatibilities in AD related prescriptions. Conclusion Treatment of TCM practitioners in all dynasties for AD mainly chooses Chinese medicinal herbs with the efficacy of tonifying qi and soothing nerves. The compatibilities and combinations are reasonable and with certain representativeness.
