Objective:To investigate the effect of celastrol on painful and the emotional of anxiety and depression comorbidity on neuropathic pain model animal and to explore its possible mechanism．Method:Mice were randomly divided into sham group， model group， pregabalin group(25 mg·kg-1)， low， medium and high-dose celastrol groups (5，10，20 mg·kg-1). The mice model of neuropathic pain were established by the L5 spinal nerve ligation (SNL). After successful modeling， the treatment groups were given intragastric administration， the sham group and the model group were given the same volume of warm water.Mechanical pain were detected by Von Frey tests， anxiety and depression behaviors were separately detected by the open field and the tail tailing experiments， the pathological changes of microglial cells in hippocampus of mice in each group were observed by immunohistochemical staining (IHC). The inflammation of BV2 microglial cell made by 1 mg·L-1 lipopolysaccharide (LPS). Real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression levels of tumor necrosis factor-α (TNF-α). The expression levels of TNF-α protein were detected by immunofluorescence（IF） staining.Result:Compared with sham group， significant change of mechanical pain thresholds， anxiety and depression were detected in the SNL mice (P<0.05，P<0.01)， the significant decreases of the body size of hippocampal microglia (P<0.05). Compared with SNL model group， 20 mg·kg-1 celastrol significantly increased the 50% paw withdraw threshold and the time of the open feld tests (P<0.05，P<0.01)，and decreased the time of the tail tailing experiments in the SNL mice (P<0.05)， and the cell body area of hippocampal microglia in SNL mice was reduced (P<0.05). Experiment in vitro show， compared with control group， the expression of TNF-α mRNA and protein expression in LPS-induced BV2 microglia increased significantly from 2-4 h (P<0.05，P<0.01). Compared with the LPS group， after 100 nmol·L-1 celastrol administration， LPS-induced microglia inflammatory factor TNF-α mRNA and TNF-α protein expression were significantly decreased (P<0.01).Conclusion:Celastrol can relieve pain-emotion comorbidity on neuropathic pain model mice， and its mechanism may be related to the anti-inflammation in the central nerves system.

Analgesic effect of Fengshi Qutong Capsules on mice with chronic inflammatory pain caused by complete Freund's adjuvant / 中国中药杂志

The aim was to observe the analgesic effect of Fengshi Qutong Capsules(FSQTC) on chronic inflammatory pain in mice, and investigate its effect on p-ERK/COX-2 signal molecular activity. A model of chronic inflammatory pain was induced in mice by complete Freund's adjuvant(CFA). The mice were divided into normal control group, model group, model+FSQTC 0.3, 0.6 and 1.2 g·kg~(-1 )groups, model+positive control drug ibuprofen(IBP, 0.34 mg·kg~(-1)·d~(-1)) group, and normal control+ FSQTC 1.2 g·kg~(-1)group. FSQTC or IBP was given once a day by oral administration. Standard Von Frey fiber was used to evaluate the mechanical pain threshold, and the acetone stimulation was used to induce inflammatory plantar and observe the cold pain reaction scores. The mechanical pain threshold and cold pain reaction scores were observed before administration and 1, 2, 3, 4, 6 h after administration on the first day, as well as 3 h after administration on the 3 rd to 7 th day. The protein levels of PGE_2, COXs-1,2 and p-ERK in the spinal cord of the inflammatory foot and lumbar 4-5 were detected by enzyme-linked immunosorbent assay, Western blot, immunohistochemistry and immunofluorescence. The results showed that the mechanical pain threshold of the model group decreased and the cold pain reaction score increased as compared with the normal group. FSQTC application could dose-dependently increase the mechanical pain threshold and decrease the cold pain reaction score. The effect lasted for 6 h, most significant at 3 h. The effect of ibuprofen was similar to that of the 0.6 g·kg~(-1) dose group. In addition, FSQTC could reduce the abnormally increased protein content of PGE_2, COX-2 and p-ERK in the inflammatory foot and/or spinal cord of the model group, and the effect was most significant in middle and high dose groups. However, it had no effect on COX-1 in the inflammatory foot and spinal cord of mice. The results suggest that FSQTC has ob-vious analgesic effect on chronic inflammatory pain in mice, which may be related to inhibition of p-ERK/COX-2 signaling pathway.

To systematically evaluate the effects of Tripterygium Glycosides Tablets alone or in combination with methotrexate(MTX) and leflunomide(LEF) on the levels of pro-inflammatory cytokines in patients or animal models with rheumatoid arthritis(RA), and to provide reference for clinical application and related basic research, this study systematically searched databases of CNKI, VIP, WanFang, PubMed, Embase and Cochrane Library, collected relevant clinical or animal experimental studies, used risk assessment tools to evaluate the quality of research, and used Revman 5.3 software to conduct Meta-analysis or descriptive analysis of the outcome indicators included in the literatures. Of the 1 709 papers retrieved, 3 clinical studies and 12 animal experiments were included. The results showed that compared with MTX alone, Tripterygium Glycosides Tablets combined with MTX could further reduce the expression levels of peripheral blood TNF-α(SMD=-8.88,95%CI[-10.77,-6.99],P<0.000 01),IL-1β(P<0.000 01) and IL-6(SMD=-8.63, 95%CI[-10.57,-6.69], P<0.000 01) in RA patients. Compared with LEF alone, the combination of Tripterygium Glycosides Tablets and LEF could not further reduce the expression levels of TNF-α(P=0.20), IL-1β(P=0.17), IL-6(P=0.31). In RA animal model, compared with model group, Tripterygium Glycosides Tablets could reduce the expression levels of peripheral blood IL-1β(SMD=-6.29,95%CI[-9.64,-2.93],P<0.000 2)in peripheral blood(SMD=-1.39,95%CI[-1.77,-1.02],P<0.000 01), joint fluid(P<0.000 01) and paw plasma(P=0.02), and also reduce the expression levels of TNF-α in RA animal model group. Compared with MTX alone, Tripterygium Glycosides Tablets alone reduced the same levels of TNF-α(P=0.42) and IL-6(P=0.08) in joint fluid, while Tripterygium Glycosides Tablets combined with MTX could further reduce the levels of IL-6(P=0.000 1) in joint fluid; compared with LEF alone, Tripterygium Glycosides Tablets have the similar effects on reducing the expression levels of peripheral blood TNF-α(P=0.16), IL-1β(P=0.32), IL-6(P=0.12), while Tripterygium Glycosides Tablets combined with LEF could further reduce the expression levels of TNF-α(P=0.008), IL-1β(P=0.02), IL-6(P<0.000 1) in peripheral blood. Therefore, Tripterygium Glycosides Tablets combined with MTX could further reduce the expression levels of pro-inflammatory cytokines in peripheral blood of RA patients. Tripterygium Glycosides Tablets alone could reduce the expression levels of pro-inflammatory cytokines in peripheral blood and local joint of RA animal models. Tripterygium Glycosides Tablets combined with MTX or LEF could further reduce the express levels of pro-inflammatory cytokines in peripheral blood of RA animal models. Due to the limitation of literature, this conclusion needs to be further validated.

Successful cure of a patient with urosepsis using a combination of extracorporeal membrane oxygenation and continuous renal replacement therapy: A case report and literature review / 中华创伤杂志(英文版)

Holmium laser lithotripsy (HLL) is one of the common surgical methods for urolithiasis. It causes minor surgical trauma, but complications are not rare. Extracorporeal membrane oxygenation (ECMO) treatment of sepsis is common, but venoarterial (VA)-ECMO treatment of urosepsis has not been reported yet. In this article, we reported a 67-year-old female patient with refractory septic shock caused by HLL under percutaneous nephroscope, involving breathing, heart, kidney and other organs, and organs support treatment was ineffective for the patient. Finally, we successfully treated the patient under VA-ECMO with continuous renal replacement therapy (CRRT). Combined ECMO and CRRT may provide a solution for addressing refractory sepsis. Here we present the case and review relevant literature, so as to provide a treatment strategy for patients with refractory urogenic sepsis and to reduce the mortality rate.
