Objective To investigate the features of intravertebral vacuum phenomenon (IVP)in vertebral compression fractures (VCFs). Methods Two hundred and nine patients with VCFs underwent percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP). The biopsies and the images of X-ray, CT, MRI of VCFs were obtained. The consistency between IVP and osteonecrosis on histology and the positive predictive value (PPV), negative predictive value (NPV), sensitivity, specificity and Youden index of IVP for diagnosing local osteonecrosis in VCFs were analyzed. Fisher exact probability test was used to analyze the coherence between IVP and osteonecrosis. Results Histological examination revealed 146(69.9%) osteoporoses, 10 (4.8%) osteonecroses with osteoporoses, 53 (25.4%) neoplasms. Prior to surgery,10 cases of IVP were found. Plain radiograph showed horizontally oriented lucent cleft in the vertebral body;CT further confirmed the location of gas;T_1-weighted MR image appeared hypointensity,while the signal intensity of T_2-weighted MR image differed, depending on the duration of recumbency. Nine of 10 patients with IVP showed osteonecrosis on histology, while 9 of 10 patients with osteonecrosis contained IVP. The association of osteonecrosis on histology and the IVP was statistically significant(P <0.01). The PPV, NPV, sensitivity, specificity, and Youden index for diagnosing local osteonecrosis was 90% (9/10), 99.5% (198/199), 90.0% (9/10), 99.5% (198/199), and 0.9, respectively. Conclusion The IVP is stongly suggestive of local osteonecrosis in vertebral compression fracture.

BACKGROUND: Compared to other preparation method, chemical extraction can almost removed all cellular components,reduce the possibility of immunological rejection, and remain the integrality of nerve graft. However, there are still problems need to be explored.OBJECTIVE: To investigate the optimal condition of acellular nerve graft using Trito X-100 and sodium deoxycholate as extracting agent.DESIGN, TIME AND SETTING: Randomized grouping, controlled cytology observation. The experiment was performed at the Department of Stomatology, Affiliated Hospital of Binzhou Medical University, from February to June 2009.MATERIALS: Fifteen New Zealand white rabbits, aged 3-4 months, weighing 2.5-3.0 kg. Triton X-100 and sodium deoxycholate were provided by Sigma Company, USA.METHODS: The bilateral facial nerve were obtained from rabbits, and removed the adipose tissue and epineurium of the nerve surface under the surgery microscope, then divided these nerves into 66 segments, with each length of 10 mm. The 66 neurons were randomly divided into 11 groups, with 6 neurons in each group. Except the control group, all neurons were placed into Petri dish for 12 hours bathing using distilled water at room temperature, then 5 groups of which were cultured with Triton X-100 for 12,24, 36, 48, and 60 hours, oscillation at room temperature; the remained 5 groups were cultured with 3% Triton X-100 for 12 hours,followed by 4% sodium deoxycholate for 12 hours, repeated for 1-5 cycles.MAIN OUTCOME MEASURES: Haematoxylin-eosin staining; degrees of decellularization and integrality of fiber pipe.RESULTS: Only use Triton X-100 to deal with the nerve of New Zealand white rabbits, even if 60 hours, could not to remove all the cellular components, and the basement membrane of Schwann cells were greatly destroyed. After 2 cycles treatment of Trito X-100 combined with sodium deoxycholate, cellular components and myelin sheath of nerve fibers and axons were removed effectively, and basement membrane of Schwann cell was remained, with epineurium and perineurium could be seen.CONCLUSION: Oscillation accompanied by 2 cycles treatment of Trito X-100 and sodium deoxycholate can obtain acellular nerve graft by removing cellular components completely, and reserving integrated basement membrane of Schwann cells.

An improved everted gut sac method was applied to the study of prescription compatibility effect on the major components in Danshen extracts. With the separation and detection by HPLC-ECD, 5 major peaks could be detected in intestinal absorbed solution after prescription administration. Following the identification by HPLC-MS/MS, peak 2, 3, 4, and 5 were rosmaric acid, lithospermic acid, salvianolic acid B, and salvianolic acid A, respectively, which also confirmed with reference standards of those components. Through paralleling substance identification, peak 2, 3, 4, and 5 could be found as the major components in Danshen extracts, except Salvianolic acid E which is undetectable in intestinal solution. The contents of peak 2, 3, and 4 did not show difference before and after compatible prescription administrated, where the peak 5 had a significant increase in the same process. Those results revealed that peak 5, salvianolic acid A, might lead to an increasing pharmacological effect after prescription compatibility.

OBJECTIVETo observe the effects of tetrahydropalmatine, dehydrocorydaline, berberine and palmatine on anoxia and peroxidation injuries in cardiomyocytes, and study the marterial basis of the anti-ischemia effect on myocardium of Rhizoma Corydalis.

METHODNeonatal rat cardiomyocytes were cultured in vitro, and subjected to an anoxia-reoxia and the hydrogen peroxide injury models. The four compounds were added into the culture medium. The cell viability was measured by MTT method to determine the safe concentrations and the anti-hydrogen peroxide injury effects of the compounds. The LDH activity in culture mediums was measured with the enzyme reaction dynamics-monitoring method to value the anti-anoxia injury effects of the compounds.

RESULTAt most up to 500 mg x L(-1), tetrahydropalmatine showed no sinificant effect on the cell viability, while dehydrocorydaline, berberine and palmatine significantly decreased the cell viability, exceeding 6.3, 0.6 and 6.3 mg x L(-1), respectively (P < 0.05 or P < 0.01). Tetrahydropalmatine, dehydrocorydaline, berberine and palmatine significantly inhibited LDH leakage induced by anoxia-reoxia injury, at concentrations of 50-100, 1.25-5, 4 and 30 mg x L(-1), respectively (P < 0.05 or P < 0.01). None of the four compounds showed significant effect on the hydrogen peroxide injury.

CONCLUSIONThe anti-ischemia effect in myocardium of Rhizoma Corydalis is related to the direct protective effects on cardiomyocytes of its components, tetrahydropalmatine, dehydrocorydaline, berberine and palmatine, amomg which tetrahydropalmatine and dehydrocorydaline are the most important, the former with high safety and low efficacy, while the latter with low safety and high efficacy. And the direct protective effects on cardiomyocytes of these four components may be attained through mechanisms other than anti-peroxidation.

OBJECTIVETo investigate the effects of lung protective ventilation strategy combined with lung recruitment maneuver on ARDS complicating patients with severe burn.

METHODSClinical data of 15 severely burned patients with ARDS admitted to our burn ICU from September 2011 to September 2013 and conforming to the study criteria were analyzed. Right after the diagnosis of acute lung injury/ARDS, patients received mechanical ventilation with lung protective ventilation strategy. When the oxygenation index (OI) was below or equal to 200 mmHg (1 mmHg = 0. 133 kPa), lung recruitment maneuver was performed combining incremental positive end-expiratory pressure. When OI was above 200 mmHg, lung recruitment maneuver was stopped and ventilation with lung protective ventilation strategy was continued. When OI was above 300 mmHg, mechanical ventilation was stopped. Before combining lung recruitment maneuver, 24 h after combining lung recruitment maneuver, and at the end of combining lung recruitment maneuver, variables of blood gas analysis (pH, PaO2, and PaCO2) were obtained by blood gas analyzer, and the OI values were calculated; hemodynamic parameters including heart rate, mean arterial pressure (MAP), central venous pressure (CVP) of all patients and the cardiac output (CO), extravascular lung water index (EVLWI) of 4 patients who received pulse contour cardiac output (PiCCO) monitoring were monitored. Treatment measures and outcome of patients were recorded. Data were processed with analysis of variance of repeated measurement of a single group and LSD test.

RESULTS(1) Before combining lung recruitment maneuver, 24 h after combining lung recruitment maneuver, and at the end of combining lung recruitment maneuver, the levels of PaO2 and OI of patients were respectively (77 ± 8), (113 ± 5), (142 ± 6) mmHg, and (128 ± 12), (188 ± 8), (237 ± 10) mmHg. As a whole, levels of PaO2 and OI changed significantly at different time points (with F values respectively 860. 96 and 842. 09, P values below 0. 01); levels of pH and PaCO2 showed no obvious changes (with F values respectively 0.35 and 3.13, P values above 0.05). (2) Levels of heart rate, MAP, CVP of all patients and CO of 4 patients who received PiCCO monitoring showed no significant changes at different time points (with F values from 0. 13 to 4. 26, P values above 0.05). Before combining lung recruitment maneuver, 24 h after combining lung recruitment maneuver, and at the end of combining lung recruitment maneuver, the EVLWI values of 4 patients who received PiCCO monitoring were respectively (13.5 ± 1.3), (10.2 ± 1.0), (7.0 ± 0.8) mL/kg ( F =117.00, P <0.01). (3) The patients received mechanical ventilation at 2 to 72 h after burn, lasting for 14-32 (21 ± 13) d. At post injury day 3-14 (7 ± 5) d, lung recruitment maneuver was applied for 2-5 (3.0 ± 2.0) d. All 15 patients recovered without other complications.

CONCLUSIONSLung protective ventilation strategy combining lung recruitment maneuver can significantly improve the oxygenation in patients with severe burn complicated with ARDS and may therefore improve the prognosis.
