ABSTRACT

Objective:To observe the effect of Yuxuebi tablets on hyperalgesia and foot swelling in mice with chronic inflammatory pain, and to explore the preliminary mechanism of action. Method:A mouse model of chronic inflammatory pain was established with left plantar injection of complete Freund's adjuvant (CFA). The mice were divided into model group, positive drug ibuprofen group (91 mg·kg<sup>-1</sup>), Yuxuebi tablets low, medium and high dose groups (55, 110, 220 mg·kg<sup>-1</sup>),with the sham operation group as the control. After successful modeling, the daily dose was divided into two doses in the morning and evening by gavage to give Yuxuebi tablets or ibuprofen to the stomach for a total of 19 days. On the 18<sup>th</sup> day after the administration, the thermal pain threshold was detected by the hot plate method. On the 19<sup>th</sup> day, the standard Von Frey fiber needle was used to detect the mechanical pain threshold of the mice, and the degree of foot swelling was scored and photographed. The liquid-phase suspension chip technology was used to quantitatively analyze 36 classic broad-spectrum inflammation-related factors like inflammatory factors and receptors. Bioinformatics were used to screen core targets and perform enzymelinked immunosorbent assay (ELISA) detection. Result:Compared with the sham operation group, the mechanical pain threshold and foot swelling score of the model froup significantly increased (<italic>P</italic><0.01), the latent time of heat sensitivity significantly decreased(<italic>P</italic><0.01), the expressions of 30 inflammatory factors in the foot increased(<italic>P</italic><0.05). Compared with the model group, the high dose of Yuxuebi tablets significantly reduced the mechanical pain threshold and foot swelling score of mice with chronic inflammatory pain(<italic>P</italic><0.01), significantly increased the latent time of heat sensitivity(<italic>P</italic><0.05), and reduced the expressions of 30 inflammatory factors in the foot(<italic>P</italic><0.05), among which tumor necrosis factor-<italic>α</italic> (TNF-<italic>α</italic>), interleukin-6 (IL-6), interleukin-17A (IL-17A), and C-C chemokine ligand 2 (CCL2) were the core targets screened out, and the expressions of TNF-<italic>α</italic>, IL-17A, and CCL2 significantly decreased (<italic>P</italic><0.01). Conclusion:Yuxuebi tablets can relieve hyperalgesia and foot swelling in mice with chronic inflammatory pain, and its mechanism may be related to the inhibition of the expressions of peripheral inflammatory factors such as TNF-<italic>α</italic>, IL-17A, and CCL2 .

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

In this study, on aspects of the nociceptive, anxiety and depressive syndromes in neuropathic pain (NP), the effects of dihydroartemisinine (DHA), artesunate (ART) and artemether (ARTN) (40 mg·kg⁻¹) were analyzed in the spinal cord ligation (SNL) mice. Clinical equivalent dose of the first-line drug for NP, pregabalin (PGB, 25 mg·kg⁻¹) and amitriptyline (ARP, 20 mg·kg⁻¹), were used as positive controls. General, from day 7 to 14, significant remissions of the nociceptive, anxiety and depressive behaviors were achieved by DHA, ART and ARTN separately. Moreover, on day 14, on aspects of the nociceptive behaviors, analyzed 1.5 h after the gavage administration, no significant difference between the shamed mice and mice administrated with DHA, ART and ARTN was detected; analyzed 3 h after the gavage, significant decreases of pain thresholds in ARTN, but not in DHA nor ART group, were detected as compared with thresholds measured 1.5 h; analyzed 24 h after gavage, pain thresholds in DHA, ART and ARTN were still higher than PGB, in spite of the significant decreases as compared to Sham group. On aspects of the anxiety and depressive behaviors, no significant difference was detected between the shamed mice and mice administrated with DHA nor ART. However, differences still remained between the shamed ones and ones administrated with ARTN. Preliminarily, the effects of DHA, ART and ARTN were consolidated in SNL mice. On aspects of the duration of analgesic effects and the control of negative emotion, ART and ARTN were proven more favorable than ARTN.

ABSTRACT

The present study was designed to prepare and compare bio-adhesive pellets of panax notoginseng saponins (PNS) with hydroxy propyl methyl cellulose (HPMC), chitosan, and chitosan : carbomer, explore the influence of different bio-adhesive materials on pharmacokinetics behaviors of PNSbio-adhesive pellets, and evaluate the correlation between in vivo absorption and in vitro release (IVIVC). In order to predict the in vivo concentration-time profile by the in vitro release data of bio-adhesive pellets, the release experiment was performed using the rotating basket method in pH 6.8 phosphate buffer. The PNS concentrations in rat plasma were analyzed by HPLC-MS-MS method and the relative bioavailability and other pharmacokinetic parameters were estimated using Kinetica4.4 pharmacokinetic software. Numerical deconvolution method was used to evaluate IVIVC. Our results indicated that, compared with ordinary pellets, PNS bio-adhesive pellets showed increased oral bioavailability by 1.45 to 3.20 times, increased C, and extended MRT. What's more, the release behavior of drug in HPMC pellets was shown to follow a Fickian diffusion mechanism, a synergetic function of diffusion and skeleton corrosion. The in vitro release and the in vivo biological activity had a good correlation, demonstrating that the PNS bio-adhesive pellets had a better sustained release. Numerical deconvolution technique showed the advantage in evaluation of IVIVC for self-designed bio-adhesive pellets with HPMC. In conclusion, the in vitro release data of bio-adhesive pellets with HPMC can predict its concentration-time profile in vivo.

ABSTRACT

Objective To explore the effect of Internet addiction on adolescent's attention.Methods Neuropsychological evaluations of attention function were done separately in 18 adolescents who met the diagnostic criterion for Internet addiction and in other 18 ones without Intemet addition tendency as a control group. With auditory and visual oddball paradigms, and stimulated by standard,target and novel stimuli, EEG was recorded and analyzed to get the event-related potential P300 and compare the latency and amplitude of P3a and P3b between the 2 groups. Results Compared with the controls, the attention of Internet addiction group was decreased significantly in neuropsychological evaluations. The latency of P3a potentials induced by novel stimulus was much shorter and the amplitude of it was higher in addiction group than in control group, but the latency of P3b potentials generated by target stimulus was prolonged and the amplitude decreased obviously.
