Chinese Journal of Tissue Engineering Research 2013;(52):9089-9094
BACKGROUND:Cannulated screw tension band combined with wire fixation is most commonly used for treatment of patel a fractures.
OBJECTIVE:To evaluate the clinical outcomes of combination of cannulated screw tension band and wire fixation in the treatment of patel a fractures.
METHODS:A literature search method was employed to retrieve relevant articles addressing cannulated screw tension band and wire fixation of patel a fractures. In-depth analysis of literatures meeting the study criteria was carried out. Patients with patel a fractures who received cannulated screw tension band and wire fixation were fol owed up to evaluate the postoperative fracture healing, complications and functional recovery of the knee joint at the injury side. Then, the clinical efficacy of cannulated screw tension band combined with wire fixation was analyzed.
RESULTS AND CONCLUSION:After treatment with cannulated screw tension band and wire fixation, patients with patel a fractures exhibited good fracture healing and low probability of complications, including screw or wire loosening, broken, and shedding. Functional recovery of the affected knee was up to 90%. Clinical case analysis showed that cannulated screw tension band combined with wire fixation achieved good outcomes in the treatment of patel a fracture, with over 90%functional recovery of the affected knee, which is consistent with the reported results. It indicates that the cannulated screw tension band combined with wire fixation is one of the ideal and reliable methods in use for internal fixation of patel a fractures.

China Pharmacist 2015;18(12):2110-2111
Objective:To investigate the thoughts and the methods of clinical pharmacists in the individual continuous renal re-placement therapy ( CRRT) anticoagulation treatment for severe patients. Methods:Clinical pharmacists participated in the CRRT anti-coagulation treatment for one patient with severe thrombocytopenia after aortic dissection surgery. Clinical pharmacists analyzed the cau-ses of thrombocytopenia and the coagulation function of the patient to exclude heparin-induced thrombocytopenia, and developed the treatment of supplementing platelets and regional citrate anticoagulation as the way of CRRT. Results:Three days after the treatment, the patient was changed to the general ward with normal renal function. Conclusion:Clinical pharmacists should participate in clinical treatment comprehensively and perform individual treatment for patients in order to ensure the effect and safety of medication.

Objective To investigate the effect of exogenous apelin-13 on oxidative stress, myocardial inflammatory cytokines and apoptosis in diabetic model rats.Methods A total of 40 male Wistar rats were randomly divided into 2 groups: normal control group (NC, n=8) and experimental group (EX, n=32).Diabetes was induced by feeding with high-sugary and high-fat diet for 8 weeks and a single intraperitoneal injection of streptozotocin (STZ) (30 mg/kg).The wellestablished 28 diabetic model rats were then randomly divided into 2 subgroups: model group (DM, n =14) and apelin-13 administration group (AP, n =14).The rats in AP group were given intraperitoneal administration of apelin-13 at a single dose of 0.1 μtmol · kg-1 · d-1 for 10 weeks, while NC group and DM group were given 0.9% NaCl in the same way.All rats were sacrificed at the end of the week 10.Blood hydrogen peroxide (H2O2), nitric oxide (NO) and malonaldehyde (MDA) were measured by colorimetry, and superoxide dismutase (SOD) was measured by enzyme-linked immunosorbent assay (ELISA).The expressions of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in rat myocardium were detected by immunohistochemistry.Masson staining was used to observe the myocardial fibrosis in rats of different groups.Cardiomyocyte apoptosis was determined by TUNEL.Results (1) Compared with NC groups, DM group showed that MDA, H2O2 and NO were significantly increased, while SOD was significantly decreased (F=22.400, 6.230, 4.267 and 8.901, all P<0.0167).There was a statistically significant difference in the levels of MDA, H2O2,SOD between DM group and AP group.(2) The expression of TNF-α and IL-6 was significantly higher inDMgroup than inNCgroup (0.0599±0.0208 vs.0.0076±0.0031, F=35.139;0.0503±0.0243 vs.0.0071± 0.0024, F=15.946, both P<0.0167).After 10 weeks of apelin-13 administration, the levels of inflammatory cytokines were significantly decreased in AP group than in DM group.(3) The myocardial apoptosis and fibrosis were significantly increased in DM group than in NCgroup [0.0293±0.0061 vs.0.0030-t-0.0013 and 0.0708±0.0420 vs.0.0013±0.0003, F=84.930 and 19.420, both P<0.0167].The myocardial apoptosis and fibrosis were significantly decreased in AP group than in DM group (both P<0.0167).Conclusions To some extent, apelin13 reduces the levels of oxidative stress and myocardial inflammation reaction in type 2 diabetes.Moreover, it may play a vital role in the improvement of myocardial apoptosis and fibrosis.

A high performance liquid chromatography-electrospray ionization mass spectrometry- charged aerosol detection ( HPLC-MS-CAD) method was established for the simultaneous quantitative analysis of four Lignans in Magnoliae Flos extract. The components were separated on a YMC-Pack ODS-A column (250 mm× 4. 6 mm, 5 μm) by gradient elution with methanol and water as the mobile phase at aflow rate of 1. 0 mL/min. Then the elution solution was routed into MS equipment at a flow rate of 0. 3 mL/min and CAD detector at a flow rate of 0. 7 mL/min by a split ratio of 3:7 for the further detection. The column temperature was 25 ℃ and the detection wavelength was 278 nm. A method was developed for the quantitative analysis of muti-components by single maker ( QAMS) to determine pinoresinol dimethylether, magnoli, 1irioresinol B dimethylethe and epi-magnoli A . Magnoli was selected as internal standard and the relative correction factors ( RCF) of the four Lignans were calculated. The contents of the four Lignans in Magnoliae Flos extract were determined by both external standard method and QAMS. The QAMS method was evaluated by comparison of its assay result and that of external standard method. Under the selected chromatographic condition, the limits of detection of pinoresinol dimethylether, magnoli, lirioresinol B dimethylethe and epi-magnoli A were 0. 34, 0. 55, 0. 50 and 0. 58 mg/L, respectively, while the linear range were within 6. 8-270 mg/L, 11-546 mg/L, 2. 0-101 mg/L and 2. 3-116 mg/L. The recoveries ( n=9 ) were 98. 2%-99. 5%, and the correlation coefficient were 0 . 9995-0 . 9998 . No significant differences were found between the quantitative results of external standard method and QAMS method. The developed method is accurate, feasible, and can be used for quality evaluation of Magnoliae Flos .
