Objective: The extract technologies for the components of Fuzhuang Capsules were optimized. Methods: Four methods: the semi bionic extraction (SBE), the water extraction (WE), the semi bionic extraction by precipitation with alcohol (SBAE) and the water extraction by precipitation with alcohol (WAE) were used to extract Fuzhuang Capsules, with panaxadiol, panaxatriol, ? sitosterol, icariine, betaine, total sugar and dried extractive taken as the marker, under the same conditions of drug granularity, solvent amount, decocting temperature, filtration, concentration, etc., and then four methods were compared and studied. Results: Through the comprehensive evaluation of seven markers, their comprehensive values Y decreased in the order of SBE, WE, SBAE and WAE. Conclusion: SBE is better than the other three methods in the extraction of the components of Fuzhuang Capsules, which is showed by the fact that the pH values of the water for the 1st, 2nd and 3rd decoctions are 3.4, 7.5 and 8.4, and the extraction times are 2.0h, 1.5h, and 1.5h respectively.

Objective To identify antimicrobial susceptibilities of community-acquired Staphylococcus aureus infections and the risk factors of severe infections.Methods Clinical data of 184 cases of community-acquired Staphylococcus aureus infections collected from 4 hospitals in Ningbo during May 2008 and May 2013 were reviewed.Microbial sensitivity test and virulence genes ( pvl and tst) detection were performed in clinical isolates, and SCCmec genotyping was performed in methicillin-resistant Staphylococcus aureus ( MRSA) strains.Binary logistic regression analysis was used to identify the risk factors for severe infections.Results Among 184 cases of community-acquired Staphylococcus aureus infections, 39 ( 21.20%) were severe cases. Staphylococcus aureus strains were highly resistant to penicillin, erythromycin and clindamycin, but more than 75% strains were sensitive to oxacillin, aminoglycosides, quinolones, rifampicin and vancomycin.Logistic regression analysis showed that advanced age (OR=1.024, 95%CI:1.005-1.043, P<0.05), malignant tumor (OR=15.288, 95%CI:1.609-145.229, P<0.05) , autoimmune diseases or long-term hormone therapy ( OR=12.102, 95%CI:2.082-70.338, P <0.01 ) were risk factors for severe community-acquired Staphylococcus aureus infections. Conclusions Strains isolated from the patients with community-acquired Staphylococcus aureus infections in Ningbo are usually sensitive to oxacillin, aminoglycosides, quinolones, rifampicin and vancomycin, which may be recommended for clinical use.Elder patients and those with malignant tumor, autoimmune diseases or long-term hormone therapy are more likely to develop severe Staphylococcus aureus infections.

BacKground:The deveIopment of acute pancreatitis( AP ) is often accompanied by pancreatic microcircuIation disturbance and aIterations in bIood coaguIation and fibrinoIytic systems, which resuIts in abnormaIities of pIateIet parameters. Aims:To investigate the changes of pIateIet parameters in eIderIy AP patients and the effect of uIinastatin ( UTI)on pIateIet parameters and disease status. Methods:Two hundred and seventeen eIderIy AP patients(≥60 years) were enroIIed retrospectiveIy from Aug. 2009 to Dec. 2013 at the First AffiIiated HospitaI of Nanjing MedicaI University. According to the severity of the disease,patients were divided into three groups:miId AP( MAP),moderateIy severe AP ( MSAP),and severe AP( SAP). The pIateIet parameters,incIuding PLT,MPV and PDW before and after treatment,as weII as the differences in pIateIet parameters and cIinicaI efficacy between conventionaI therapy and UTI therapy were compared and anaIyzed. Results:In MSAP and SAP groups,PLT at admission was significantIy Iower(P<0. 01),whiIe MPV and PDW were significantIy higher(P<0. 05)than those in MAP group. After 1-week treatment,PLT increased significantIy(P<0. 01)and MPV and PDW decreased significantIy(P<0. 05)in MSAP and SAP groups. UTI therapy was superior to conventionaI therapy in increasing PLT( P <0. 01 ),decreasing MPV and PDW( P <0. 01 ),and improving the overaII efficacy in MSAP and SAP groups( MSAP:92. 3% vs. 81. 2%,P <0. 01;SAP:90. 0% vs. 80. 8%,P<0. 01). Conclusions:Changes of pIateIet parameters in eIderIy MSAP and SAP patients are different from those in MAP patients,which might refIect the disease severity. UTI is effective in reducing the activity of pIateIet and can be used in the treatment and prevention of disease progression in eIderIy AP patients.

Objective: To explore and evaluate the biomechanic relationships between different depth of pedicle screw penetration with the sagittal plane reconstruction in thoracolumbar fracture. Methods:Six fresh cadaveric specimens of lumbar spine from L_1 to L_3 were used to make the model of thoracolumbar fracture. The system of universal spine system( USS )pedicle screw was adopted with the 6 mm diameter of screw. Each of two Schanz screws was implanted into the pedicles of L_1 and L_3 A canulated screw was fixed into the former of vertebral body in L_1 and L_3, and the distance of the two canulated screws was taken as the normal height. The axial loads were given while the pedicle screws were implanted at the depth of D1, D2 and D3, and the distance of the two canulated screw was measured as well as the distance was reduced to the normal height by axial load. The index measured included of the depth of pedicle screw penetration, the height of fractured vertebral body and afterload. Results: Along with the increasing of afterload, the height of injured vertebral body was increased accordingly, but the extent was different at three depth of pedicle screw penetration (D1, D2, and D3). While the injured vertebral body was reduced totally (reduced distance 0.00 mm), there was (2 630±13) g of afterload needed in Dl depth, and (2 339±61) g and(2 221± 164) g of afterload in D2 and D3 depth respectively. There was significant difference in distance between D1, D2 and D3 (P< 0.01), however, no significant difference between D2 and D3 (P> 0.05). Conclusion: There is a relationship in the depth of pedicle screw penetration, the capacity of reduction and sagittal plane reconstruction. The depth of pedicle screw had a significant effect on the capacity of reduction for the injured vertebral body, which would be the best option in biomechanics when the pedicle screw was implanted more than 1/2 pedicle or all of it.

Objective To detect the proliferation inhibition and apoptosis of HL-60 cell induced by APS-1 and APS-2 isolated from Polyporus sp. M05 and to investigate its mechanism. Methods The proliferation inhibition was detected by living cells count method,and chosed proper concentration.Flow cytometry with propidium iodide staining was used to detect cell apoptosis. Semi-quantitative RT-PCR was used to detect the expression of apoptosis related gene. Results APS-1 and APS-2 could significantly inhibit the proliferation of HL-60 cells on a time and dose dependent manner. Apoptosis ratio increased to 47. 9% and 26. 8% after HL-60 cells were exposed to APS-1 and APS-2 respectively for 48 h,and the differences had statistical significance (P <0.01). After being induced by APS-1,mRNA of Bax,Fas,Caspase-3 was upregulated. And after being induced by APS-2,mRNA of Bax,Caspase-3 was upregulated,while Fas mRNA did not change. Conclusion APS-1 and APS-2 can inhibit the proliferation and induce apoptosis of HL-60 cells. Mechanism of HL-60 cell apoptosis induced by APS-1 is related to both mitochondrial pathway and Fas signaling pathway,while apoptosis induced by APS-2 is only related to mitochondrial pathway.
