Objective:To observe the effects of moxibustion on serum levels of interleukin (IL)-6, IL-8 and tumor necrosis factor-α (TNF-α), and to explore the effects of moxibustion on inflammatory damaging factors in experimental rheumatoid arthritis (RA) model rats; the relationship between the therapeutic effect of moxibustion on RA and the change in the Toll-like receptor (TLR) signaling pathway was analyzed using Toll-like receptor 4 (TLR4) antagonists and agonists. Methods:Fifty Sprague-Dawley (SD) rats were divided into a normal group, a model group, a moxibustion group, a moxibustion plus TLR4 agonist group (agonist group) and a moxibustion plus TLR4 antagonist group (antagonist group) according to the random number table, with 10 rats in each group. Except the normal group, rats in the other four groups were subjected to model preparation with the wind, cold and wet environmental factors plus Freund's complete adjuvant (FCA). Rats in the normal and model groups were not treated; rats in the moxibustion, agonist and antagonist groups started to be treated with the moxibustion (cigarette-type moxa) at bilateral Shenshu (BL 23) and Zusanli (ST 36) from the 4th day after the successful modeling, for 20 min each time with a total of 10 d. Rats in the agonist and the antagonist groups were injected with TLR4 agonist or antagonist [0.1 mg/(kg·bw)] via the tail vein 30 min before moxibustion. The concentrations of serum IL-6, IL-8 and TNF-α in each group were determined by enzyme-linked immunosorbent assay (ELISA). Results:Compared with the normal group, in the model group, the rat's right hind paw swelling was significantly obvious (P<0.01), there was a lot of inflammatory infiltration in the synovial tissues, the surface of the synovial membrane was unsmooth, the synovial membrane was hyperplasia and thicker, and the serum IL-6, IL-8 and TNF-α concentrations increased significantly (P<0.05). Compared with the model group, the paw swelling degrees of the rats in the moxibustion, the agonist and the antagonist groups reduced significantly (allP<0.01); the swelling degree in the antagonist group was milder than that in the agonist group, but the between-group difference was not statistically significant (P>0.05); inflammatory infiltration and synovial membrane hyperplasia in the synovial tissues of the moxibustion group and the antagonist group were all relieved differently; the decrease of synovial layer number in the moxibustion group was more obvious, and there were no obvious improvements in inflammatory infiltration and synovial thickness in the agonist group; the concentrations of IL-6, IL-8 and TNF-α in the moxibustion group were decreased, and the differences in the IL-6 and TNF-α concentrations were statistically significant (allP<0.01); there was no significant between-group difference in the IL-8 concentration (P>0.05); the concentrations of serum IL-8 and TNF-α in the agonist group increased significantly (both P<0.01), while the IL-6 concentration decreased without significant difference (P>0.05); the concentrations of IL-6 and IL-8 in the antagonist group decreased but the between-group differences were statistically insignificant (bothP>0.05), and the TNF-α concentration significantly increased (P<0.05). Compared with the moxibustion group, IL-6, IL-8 and TNF-α concentrations increased in the agonist group, and the differences in the IL-8 and TNF-α concentrations were statistically significant (both P<0.01); the concentrations of IL-6, IL-8 and TNF-α increased in the antagonist group, and the differences in the IL-6 and TNF-α concentrations were statistically significant (bothP<0.01); there was no significant difference in the IL-8 concentration between the groups (P>0.05). The serum levels of IL-6, IL-8 and TNF-α in the antagonist group were lower than those in the agonist group (allP<0.05). Conclusion:Moxibustion at Shenshu (BL 23) and Zusanli (ST 36) can reduce the joint swelling degree and inflammation in synovial tissue of RA model rats, decrease the serum levels of IL-6, IL-8 and TNF-α in RA model rats; the decreases of IL-6 and TNF-α are more significant than the decrease of IL-8; TLR4 agonist and antagonist can significantly attenuate the effect of moxibustion in inhibiting releases of IL-6, IL-8 and TNF-α, so that the change in TLR signaling pathway affects the effect of moxibustion in inhibiting the releases of IL-6, IL-8 and TNF-α.

Short tandem repeats (STRs) have been widely used in forensic sciences such as stain analysis and paternity testing. Although most of STR typing could give the reliable and clear results, some unusual typing have been observed in forensic practice. The anomalous typing could result from a lot of causes, including DNA genetic variation, poor quality or quantity of DNA template, different typing system or method, nonspecific reaction in PCR or anomalous electrophoresis migration. The unusual results may disturb the right interpretation of STR typing.

Objective To evaluate the applied value of percutaneous oxygen-ozone injection in the treatment of lumbar disc herniation under open 0.23 T MRI guidance.Methods Mounted with ipath 200 optical tracking system,MR-guided injection of oxygen-ozone were performed via a medial border of the articular processes approach in 73 patients with clinically diagnosed LDH.MR compatible 19.5G or 21.0 G biopsy needle was used. Discography was performed in order to select indication before injection oxygen- ozone into nucleus pulposus in 26 patients.Sixty-four patients were injected to three sites:(1)Six to 10 ml oxygen-ozone was injected into discs centers,injected and suctioned alternately in order to make nucleus pulposus oxidation thoroughly.(2)The needle was withdrawn according to the scale of biopsy needle and optical tracking.Then,10 ml oxygen-ozone was injected into disc herniation. (3)After that,needle was withdrawn further about 1.0—1.5 cm to outside of annulus fibrosus.Fifteen to 20 ml oxygen-ozone was injected into intervertebral foramina around nerve roots.The oxygen-ozone concentration was 35—45?g/ml. Nine patients were only performed injection of oxygen-ozone into around nerve root,while not injection oxygen-ozone to nucleus pulposus for considering bad curative effect after discography.Results All of 73 patients were successfully local targeted and treated under MRI guidance without serious complications, such as nerve root injury.After 3—6 months follow-up,total overall efficacy was 91.3% with the excellent in 28,good in 39,and poor in 6,respectively.Conclusion Open MR-guided injection of oxygen-ozone, mounted with optical tracking system,is a safe and effective minimally invasive therapy for treating LDH.

The high performance liquid chromatography-fluorescence micelle assay (HPLC-FMA) method for the content determination of polysorbate 80 in monoclonal antibody drugs was validated to study its applicability and transferability between various laboratories, and the feasibility to be included in the Chinese Pharmacopoeia. Both J.T. Baker and Nanjing Well-sourced polysorbate 80 was used in the collaborative validation of polysorbate 80 content analysis in seven different laboratories. The results show that when the protein concentration was no more than 20 mg·mL^-1 and the concentration of polysorbate 80 ranged from 0.05 to 0.5 mg·mL^-1, the method had good specificity. The recovery rates of the spiked samples ranged from 92.20% to 117.70% for J.T.Baker and from 93.90% to 117.20% for Nanjing Well. The intra-laboratory precision (%RSD) was less than 4.30% for J.T. Baker, and less than 2.60% for Nanjing Well, while the overall precision was less than 5.45% for J.T. Baker, and less than 6.70% for Nanjing Well. The linear correlation coefficient was more than 0.98 for J.T. Baker and more than 0.99 for Nanjing Well. The results of the collaborative validation prove that the HPLC-FMA method has good accuracy, precision, linearity, and specificity, and could be used for release control analysis of polysorbate 80 content in monoclonal antibodies across different laboratories.

Psoriasis is an immune-abnormal, chronic, proliferative skin disease determined by polygenic inheritance and induced by a number of environmental factors. It causes worldwide concern because of its high-prevalence, harmful and incurable characteristics. Over the years, Chinese medicine (CM) treatment of psoriasis has accumulated a wealth of clinical experience. Disease-syndrome combination, which achieves more satisfactory clinical effect, is the basis to highlight the special CM advantages in treating psoriasis. In this paper, we review the advantages of treating psoriasis with the combination of disease and syndrome, analyze the prospects of research on treating psoriasis combining disease with syndrome. We also make a point that there are several key points for the clinical research of combination of disease and syndrome. It can be expected that carrying out clinical research on the combination of disease and syndrome will help improve the clinical efficacy of medical treatment of psoriasis, which will be the main direction of research in the future.

In this study, we evaluated the difference ot biological characteristics in the MERS-CoV infected mice model in prior to transduction with different dosage of human DPP4. Firstly, we transduced different dosage of DPP4 (high or low) into mice, and then challenged them with MERS-CoV in order to establish the model. After establishment of mice model, we observed the clinical signs of disease, virus replication, immunopathogenesis and antibody response. The results indicated that the infected mice showed typical pneumonia, virus replication, histological lesions, and neutralizing antibody production. Moreover, the high dosage group was superior to the low dosage group. Fourteen days after infection, the specific antibody to virus structural protein and neutralizing antibody were analyzed, the high dosage group induced higher level antibody. In summary, the MERS-CoV infected mice model were established prior transduction with DPP4, and the level of DPP4 influenced the clinical signs of disease, virus replication and antibody response in this model.

To determine whether Smac/DIABLO (second mitochondrial activator of caspases/direct inhibitor of apoptosis protein-binding protein of low isoelectric point [PI]) and XIAP (X-chromosome-linked inhibitor of apoptosis protein) serve to regulate neuronal apoptosis following seizures, we investigated seizure-induced changes in caspase-9, Smac/DIABLO and XIAP protein expression and the in vivo effect of caspase-9 inhibition. Animals received unilateral intra-amygdaloid injection of kainic acid (0.5 microg) to induce seizures for 1 h. The seizures were then terminated by diazepam (30 mg/kg). Animals were killed 0, 2, 4, 8, 24 or 72 h following diazepam administration. The apoptotic and surviving neurons in hippocampus were observed by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) and cresyl violet staining, the expression of Smac/DIABLO, XIAP and caspase-9 was detected with immunofluorescence and western blot. The results showed that the levels of XIAP and the 46-kDa proenzyme form of caspase-9 were unaffected by the seizures. The expression of Smac increased at 2 h and the 37-kD cleaved fragment of caspase-9 was detected at 4 h, TUNEL-positive neurons appeared at 8 h and reached maximal at 24 h following seizure cessation within the ipsilateral (the same side as the intra-amygdaloid injection of kainic acid) CA3 subfield of the hippocampus. Intracerebroventricular infusion of caspase-9 inhibitor z-LEHD-fluoromethyl ketone (z-LEHD-fmk) significantly decreased TUNEL-positive neurons and increased the number of surviving cells. Caspase-9 immunoreactivity increased and Smac/DIABLO, XIAP immunoreactivity became extensive within the ipsilateral CA3 neurons. TUNEL-positive neurons and the alterations of the expression of Smac/DIABLO and XIAP within the ipsilateral CA3 were not detected within the contralateral hippocampus. These results suggest that seizures lead the translocation of Smac/DIABLO into the cytosol, the activation of caspase-9 and the change of subcellular locoalization of XIAP. These changes may play a role in the brain damage induced by seizures. Caspase-9 is possibly a potential therapeutic target in the treatment of brain injury associated with seizures.
