The marine biological source of mineral drugs recorded in Chinese Pharmacopoeia (2010 version) mainly including pearl, nacre, clam shell, common oyster shell, ark shell, cuttle bone, and sea-ear shell are widely used in clinical. Calcium carbonate and a small amount of protein are the main components in this type of drugs. In this paper, a systematical and comparable study were carried out by determination of calcium carbonate by EDTA titration method, the crystal of calcium carbonate by X-Ray powder diffraction and the total amino acids (TAAs) of the hydrolyzed samples by ultraviolet spectrophotometry method. As a result, the crystal structure is calcite for common oyster shell, mixture of calcite and aragonite for nacre and sea-ear shell, aragonite for the other drugs. The content of calcium carbonate ranged from 86% to 96%. Cuttle bone has the highest amount of TAAs among the seven drugs which reached 1.7% while clam shell has the lowest content of 0.16% on average. In conclusion, an effective method was developed for the quality control of marine mineral drugs by comprehensive analysis of calcium carbonate and TAAs in the seven marine mineral drugs.

Objective To explore the biological activities and the MR imaging signal intensities (SIs) characteristics of differentiations of neural-like cells induced by superparamagnetic iron oxide (SPIO)
and green fluorescent protein (GFP) double-labeled bone marrow-derived mesenchymal stem cells (BMSCs) in vitro. Methods GFP-BMSCs were labeled with different concentrations of SPIO in vitro (the concentration of the A, B, C and D group was 25, 50, 75 and 100 ug/ml, respectively;the E group without labels of SPIO served as the control group). The Prussian blue stainings were used to detect the labeling rates of SPIO. The iron contents of cells were measured by atomic absorption spectrometer. The CCK8 experiments were used to detect the cell proliferation rates. The cell cycles were detect by PCR. Each of the A-E groups had a test tube with 1 × 108 cells. All test tubes underwent T2* weighted imaging (T2*WI) and susceptibility weighted imaging (SWI) in a MR imaging scanner. The optimal group was defined by comparing the measurements of SIs between T2*WI and SWI. The optimal group and the E group together induced the differentiations of osteogenesis and neural-like cells. The stainings of alizarin red, osteocalcin and Nissl, NeuN, and NF-200 were performed at 72 hours. Real-time quantitative PCR was used to detect the expression levels of RNA in tub3, nestin, NSE, MAP-2 and Syt1. The positive staining rates and the expression levels of RNA were compared between the two groups. Finally, SWI was used to analyse the changes of SIs. One-way analysis of variance (ANOVA) was used to the multi-group comparison. Using least significant difference (LSD) test to analyse the comparisons between the multi-groups. Results The labeling rates of the A-D groups were 100%. The iron contents of cells in the A-E groups were (14.36 ± 7.61), (21.73±3.42), (30.54±8.73), (33.65±9.62), and (2.31±0.32) pg/cell, respectively. The iron contents of cells in the A-D groups were significantly higher than those in the E group ( F=3.852, P=0.003). There was no significant difference between the C and D groups (P=0.267). In all groups, the D group had the lowest OD value in the CCK-8 experiments (3.18 ± 0.46). In the A-E groups, the changes of SIs in SWI were significantly lower than those in T*2 WI. There was no significant difference in SIs of SWI between the C group (145.89±14.31) and the D group (127.37±12.21). Except the comparison between the group C and D, the comparisons between all the groups had significant differences (P<0.001). The percentages of SI attenuations in SWI and T*2 WI were 48.15% and 69.34%, respectively. The proportions of non-neurons cells and the positive rates of Nissl's stainings in group C and E had no significant differences (P>0.05). The expression levels of tub3, nestin and NSE were significantly higher before than after induced differentiations (P<0.01). SIs of SWI had no significant difference between before and after induced differentiations in the C group (t=1.26, P=0.236). Conclusions SPIO and GFP double-labeled BMSCs can induce neural-like cells without influencing biologic activities. MR SIs are decreased by the increase of SPIO concentrations in cells. SWI was the most sensitive sequence. The SIs of SWI has no differnce between before and after induced differentiations.

OBJECTIVETo explore the surgical method and its clinical effects of minimally invasive osteosynthesis on the treatment of complex ankle fractures.

METHODSFrom January 2007 to December 2011, 53 patients with complex ankle fractures were treated with minimally invasive osteosynthesis. There were 31 males and 22 females, with an average age of 38.2 years old (ranged, 18 to 65). According to the system of Lauge-Hansen, 32 fractures were supination external rotation injury (grade WV), 13 fractures were pronation external rotation (grade III or IV), 5 fractures were pronation abduction (grade III); and 3 fractures can not be classified due to serious comminution fracture of fibula. According to the system of Denis-Weber, there were 4 cases with type A, 34 cases with type B and 15 cases with type C. Seven cases were open fractures. The duration from injuries to operation ranged from 2 hours to 14 days with an average of 5 days. The sequence of reduction and fixation of ankle fractures was firstly posterior malleolus, then medial malleolus and lateral malleolus, and inferior tibiofibular syndesmosis lastly. The fractures of posterior malleolus were reduced and fixed through anterior ankle approaches; the fractures of medial and lateral malleolus were percutaneously fixed with bolts or blade plate or tensile force band; and inferior tibiofibular syndesmosis were firmly fixed if necessary. Baird-Jackson scoring system was used to evaluate clinical effects.

RESULTSForty-eight patients were followed up from 10 to 36 months with an average of 13 months. The fractures got healing with an average time of 12 weeks (ranged, 10 to 18). According to the Baird-Jackson scoring system, the mean score of ankle function was 94.7 +/- 4.2, and 28 cases obtained excellent results, 15 good, 3 fair and 2 poor. One case experienced superficial infections and was cured by changing dressings, 2 cases experienced fixed syndesmosis screw breakage.

CONCLUSIONThe surgical method of minimally invasive osteosynthesis can ensure the anatomical join restoration, protect the blood supply of fracture end, rebuild the function of ankle joint, obtain satisfactory clinical results in treating complex ankle fractures.
