OBJECTIVETo observe the clinical effect of Chinese medical (CM) syndrome differentiation based Chinese herbs and recombinant human tumor necrosis factor receptor II-antibody fusion protein (etanercept) for treating ankylosing spondylitis (AS) patients.

METHODSTotally 35 AS patients were treated with syndrome differentiation based Chinese herbs and etanercept. Reinforcing Shen and strengthening Du channel, activating meridians to stop pain was principle used in syndrome differentiation based treatment. Etanercept was subcutaneously injected, 25 mg each time; twice per week for the first three months and once a week for the latter three months. The clinical efficacy was evaluated after 3 and 6 months of treatment. Meanwhile, ASAS20 and ASAS50 standards arriving rates were also observed. Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), visual analog score (VAS) for spine pain, VAS for night pain, patient global assessment (PGA), VAS for physician global assessment, CM syndrome score, finger-ground distance, thoracic activity, tragus-wall distance, lumbar scoliosis, cervical rotation, Schober improved test, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were observed before treatment, 3 and 6 months after treatment.

RESULTSCompared with before treatment, BASDAI, BASFI, VAS for spine pain, night pain, physician global assessment, PGA, CM syndrome score, finger-ground distance, thoracic activity, tragus-wall distance, lumbar scoliosis, Schober improved test, ESR, and CRP all decreased after 3 and 6 months of treatment, with statistical difference (P < 0.05). Cervical rotation also decreased after 6 months of treatment, with statistical difference (P < 0.05). Compared with 3 months of treatment, total effective rate of CM syndrome, ASAS20 and ASAS50 standards arriving rates increased after 6 months of treatment, with statistical difference (P < 0.05). There were statistical differences in all indices mentioned above between after 3 months of treatment and after 6 months of treatment (P < 0.05).

CONCLUSIONSyndrome differentiation based Chinese herbs combined etanercept could alleviate inflammatory reaction favorably, control the progression of active AS, and improve joint functions.

Study on the effects of Astragali Radix main active flavone calycosin-7-O-β-D-glucoside on Saposhnikoviae Radix main active ingredients prim-O-glucosylcimifugin and cimifugin, a UPLC-MS/MS method for simultaneous determination of prim-O-glucosylcimifugin and cimifugin in rat plasma was established, and the comparative pharmacokinetics of prim-O-glucosylcimifugin and cimifugin after oral administration of prim-O-glucosylcimifugin and calycosin-7-O-β-D-glucoside-prim-O-glucosylcimifugin to rats were carried out, which might be conductive in exploring the rationality of Astragali Radix - Saposhnikoviae Radix herb couple. Twelve male SD rats were divided into two groups. Prim-O-glucosylcimifugin and cimifugin in rat plasma of different time points after oral administration of prim-O-glucosylcimifugin and calycosin-7-O-β-D-glucoside - prim-O-glucosylcimifugin to rats were determinated. And the main pharmacokinetic parameters were investigated using DAS 3. 2. 4. The established method was rapid, accurate and sensitive for simultaneous determination of prim-O-glucosylcimifugin and cimifugin in rat plasma. The analysis was performed on a Waters Acquity BEH C18 column (2.1 mm x 100 mm, 1.7 μm) with the mixture of acetonitrile and 0.1% formic acid/water as mobile phase, and the gradient elution at a flow rate of 0.3 mL x min(-1). The analytes were detected by tandem mass spectrometry with the electrospray ionization (ESI) source and in the multiple reaction monitoring (MRM) mode. Compared with prim-O-glucosylcimifugin group, the AUC(0-t)., and AUC(0-∞) of p-O-glucosylcimifugin as well as the C(max) of cimifugin significantly increased (P < 0.05) in calycosin-7-O-β-D-glucoside-prim-O-glucosylcimifugin group. Calycosin-7-O-β-D-glucoside could enhance the absorption of prim-O-glucosylcimifugin and cimifugin and improve the bioavailability, explaining preliminarily the rationality of Astragali Radix-Saposhnikoviae Radix herb couple.

To compare the difference of total phenol of magnolia solid dispersion prepared by different methods. Hot melt extrusion, solvent evaporation method, and fusion-cooling method were used to prepare total phenol of Magnolia accessory solid dispersion, Plastone S-630 and HPC. The drug dispersion state in the prepared solid dispersion was evaluated with DSC and X-ray diffraction; FT-IR method was used to analyze the possible connections between drug and accessories. Finally, accelerated stability-in vivo dissolution test was use to compare the stability differences between these three processes. The results of DSC and X-ray diffraction showed that all of the drug in solid dispersion processed by three processes can exist in amorphous form; FT-IR results also could not distinguish the difference between the three processes; accelerated stability-in vivo dissolution test showed the stability of solid dispersion prepared by HPC was better than Plastone S-630, and the same kinds of materials solid dispersion prepared by hot melt extrusion showed a better stability than the other two processes.

Endoscopic ultrasonography has been widely used in the diagnosis of digestive system disease,and has great important diagnostic significance in the differential diagnosis of the upper gastrointestinal mucosa or submucosal lesions,as well as to distinguish the gastrointestinal intracavitary and extracavitary lesions.At the same time,EUS can more accurately judge the depth of tumor invasion and the surrounding lymph node metastasis,which has great value in the preoperative TNM staging of esophageal cancer and gastriccancer,the judgment of resectability and the prognosis.We summarized the result of EUS in the upper gastrointestinal disease in our hospital.

ObjectiveTo examine the protective effects of 17-β estradiol on the experimental model of spinal cord injury (SCI) rats. Methods One hundred and eighty male Sprague Dawley (SD) rats, after Allen' s model, SD rats were divided into three groups: the sham group, the acute spinal cord injury (control groups) and the acute spinal cord injury supplying with 17-β estradiol treatment group. SCI was made by Allen's weight dropping, impacting on the posteriors of spinal cord T10. The content of malonyldialdehyed (MDA), glutathione (GSH), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) were determined by chromatometry. The expressions of Caspase-3 and Bcl-2 family in the injured spinal cord were detected by immunohistochemical staining. Results The BBB scores at each time point in 17-β estradiol treatment group were significantly higher than that in SCI group (P<0.05). The contents of GSH, SOD, GSH-Px and the expression of Bcl-2 protein at the majority of time point in 17-β estradiol treatment group were significantly higher than that in SCI group(P<0.05), however, the MDA, Caspase-3 and Bax were markedly decreased (P<0.05). Conclusions This study suggests that 17-β estradiol administration might prevent the cells from SCI-induced apoptosis by triggering to reduce the oxidative stress.

ObjectiveTo investigate the CT number linearity of the cone-beam CT (CBCT) images at the different spatial locations in the scanning area.MethodsThe CatphanS04 phantom at the different locations are scanned repeatcdly using the CBCT on the Varian 23EX linear accelerator.The phantom is located the isocenter point,eccentric 3 cm,eccentric 6 cm,and different points on the z-axis successively on the accelerator.The scanned mode is the standard head mode.The reconstructive thickness is 2.5 cm.The different densities inserts of CTP404 module on the different locations are measured via Eclips treatment planning system (TPS) and computed by Matlab 7.0 and the CT linear fitting are then processed.In order to understand better the linear distribution along with the value of CT in the spatial distribution the results are compared with the fan-beam CT.ResultsPhantom studies show that:CBCT has good linearity performance not only under the standard header (body) of the scanning conditions,but also on such locations including the cross-sectional,the sagittal,the coronal plane and the eccentric position ( R2 ＞ 0.953 ).Bowtie filtration device does not change the CT finearity but changes the value of CT.ConclusionsThe linearity of X-ray CBCT on the Varian linear accelerator is favorable.CBCT will be used in the TPS dose calculation via further correction of the CT value.
