Objective To prepare celastrol ethosomes and to observe the permeability characteristics of the ethosomes which act as the transdermal delivery carriers of celastrol in vitro. Methods Celastrol ethosomes were prepared by ethanol injection method, and then the encapsulation efficiency, particle size, polydispersity index ( PDI) and zeta potential of the ethosomes were analyzed. TP2A intelligent percutaneous penetration instrument was used to compare the skin penetration properties of celastrol ethosomes, celastrol solution and the mixture of blank ethosomes with celastrol solution. Results The prepared celastrol ethosomes were spherical, and the average particle size was (401.3 ± 5.5) nm, PDI was 0.21± 0.02, steady zeta potential was (-2.75 ± 0.1) mV, and average encapsulation efficiency was ( 80.6 ± 0.7) %. The amount of accumulative penetration of celastrol ethosomes at 48 h was 76.86 μg·cm -2 and the permeation rate was 1.640 9 μg·cm -2·h -1, which were significantly higher than the celastrol solution and the mixture of blank ethosomes with celastrol solution. Conclusion The prepared ethosomes have high encapsulation efficiency, uniform particle size and stable quality, and are beneficial to the transdermal absorption of celastrol.

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.

Purpose:To study the efficiency and the safety of recombinant human erythropoietin (rHuEPO) in the treatment of chemotherapy-induced anemia.Methods:41 tumor patients were randomized into two groups:EPO-treatment group and control group,in order to observe the changes of the haemoglobin level,transfusion requirement and quality of life for the two groups respectively.Results:①the increase of haemoglobin level and the quality of life in the EPO-treat- ment group compared with that in the control group was statistically significant.②the reduction of transfusion requirement in the EPO-treatment group compared with that in the control group was not statistically significant.③treatment of EPO has few side-effects and a good tolerance.Conclusions:rHuEPO in the treatment of chemotherapy-induced anemia is effec- tive and safe.Not only can it increase the haemoglobin level but also improve the quality of life for the patients,so it should be used widely.

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.

Objective To investigate the chest HRCT characteristics of pediatric perinuclear anti-neutrophil cytoplasmic antibody (p-ANCA) associated systemic vasculitis. Methods Retrospectively analysis of the clinical and HRCT data of 15 pediatric cases diagnosed as p-ANCA related pneumonia according to the classification and diagnostic criteria of Chapel Hill meeting of 1994 in our hospital were retrospectively analyzed. They were 13 girls and 2 boys. The age range was 1—17 years and the median was about 10 years old, In the 15 patients, 12 were diagnosed as primary MPA, 2 were secondary MPA, 1 was CSS. Two radiologists with 10 years of radiological experience read the CT imaging together. Results 1 of 12 primary MPA were found large opacities and ground glass shades in both sides of lung,especially the posterior parts on CT images with bilateral pleural effusion; 1 case had focal opacities in left lower lobe, around with thickened interlobular septa and pleural effusion; Another 1 case only had focal thickened interstitial in right middle lobe; The other 9 cases showed scattered or diffused ground glass opacity, with thickened pulmonary interstitial and (or) pleura. 1 of the 2 secondary MPA who had hemoptysis showed ground glass opacity on CT images with no thickened septal nodules or pleural effusion. The other one who had renal anomalies and no respiratory symptoms showed subpleural nodules with halo sign in right low lobe. The CSS showed diffused patchy ground glass opacity, consolidation of both lingular lobes, nodules of centri-and peri-lobular, thickened septa near the pleura, obviously thickened bronchial wall, slightly widened bronchial lumen and thickened pleura. Conclusion The classic imaging features of p-ANCA pneumonia on HRCT is the non-specific small pulmonary vessel hemorrhage.

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.

Objective To evaluate the effect of home-made immobilization device with KV-CBCT in lung-SBRT and investigate its clinical use value.Methods Choosing 10 lung tumor patients (half centre type tumor;half peripheral type) random analysis the interfractional and intrafractional setup errors in the SBRT process by this fixed device with KV-CBCT.The concrete method is using Varian's KV-CBCT scans the patients before and after the SBRT each time,then make the registration between the reconstructed 3 d image and the planned CT image (both based on bone landmark),we then obtain the average setup errors in LR,AP and SI directions.Simultaneously,this research make contrastive analysis of setup errors among this fixed device and other fixed devices such as vacuum pad,phantom in body IMRT.All data make one-factor analysis of variance by SSPS 17.0.Results All the setup errors data was gaussian distribution,the centre type interfraction was at (0.01 ±0.32) cm (LR),(-0.08 ±0.38) cm (AP),(0.14 ±0.36) cm (SI) of the cross section,peripheral type interfraction was at (0.01 ± 0.32) cm (LR),(-0.08 ± 0.38) cm (AP),(0.14 ± 0.36) cm (SI) of the cross section (P =0.001).We found out that the average of lung tumor's setup error at all three directions have no significant difference-the largest was the AP directions (P =0.003),the second was the SI direction (P =0.003) and the smallest was the LR direction (P =0.001).The central type has no significant difference at three directions.Compare to the other fixed device,the average setup errors of our device are (0.09 ± 0.33) cm (LR),(-0.10 ± 0.44) cm (SI),(0.17 ±0.35) cm (AP) better than the report at present paper.As the interfraction setup error was small enough by using this fixed device while it has beyond the system algorithm,the registration software of system shows (0.0 ± 0.0 cm).Conclusions The range of lung tumor motion can be cut down obviously and enhance each placement accuracy,repeatability,on SBRT with home-made immobilization device.

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.
