RESUMEN
BACKGROUND: Moxibustion has been recognized as an effective approach for ulcerative colitis, yet its mechanism is not clear. The research aimed to investigate the influence of moxibustion on the activation of NLRP3 inflammasome and its mechanism in treating ulcerative colitis by observing miR7/RNF183 inducing IκB α ubiquitination to regulate NF-κB signaling pathway in an ulcerative colitis rat model. METHODS: An ulcerative colitis rat model was established by unlimited access to self-administration of 3.5% (w/v) dextran sulfate sodium solution. Mild moxibustion was applied to bilateral Tianshu points (ST25) in the moxa-stick moxibustion group; rats in the control group were intervened by intraperitoneal injection of ubiquitination inhibitor, MG132. The disease activity index was determined at the end of the intervention; colon injury was observed and scored after hematoxylin-eosin staining; the immunohistochemical method was adopted to detect the expressions of colonic IL-1ß and NLRP3 proteins; Western blot determined the expressions of RNF183, IκB α, and NF-κB p65 proteins in the colon; the immunofluorescence test was used to observe the coexpression of IκB α/ubiquitin and IκB α/RNF183 proteins in the colon; immunoprecipitation assay was adopted to observe the interaction between IκB α and RNF183 proteins; and quantitative real-time polymerase chain reaction determined the expression of colonic miR7. RESULTS: Moxibustion lowered the disease activity index, manifesting as restored colonic tissue and reduced inflammatory reaction, and decreased expression levels of NLRP3 and IL-1ß proteins, compared with the model group. It also reduced colonic expression of NF-κB p65 protein, together with the increased level of IκB α protein and weaker expression levels of ubiquitin and RNF183 proteins and mRNAs and stronger expression of miR7. There were no significant differences between the moxa-stick moxibustion group and the control group except the expressions of RNF183 protein and mRNA and miR7. CONCLUSION: Moxibustion encourages the recovery of colon injury probably by regulating the expression of NLRP3 protein in ulcerative colitis rats through miR7/RNF183/NF-κB signaling pathway.
RESUMEN
Crohn's disease is a chronic inflammatory bowel disease and the NLRP3 inflammasome plays an important role in Crohn's disease. Previous studies have shown that Herb-partitioned moxibustion treating (at Qihai (CV 6) and Tianshu (ST 25)) prevented the excessive activation of the NLRP3 inflammasome and repaired damaged colonic mucosa in Crohn's disease. However, the mechanism by which Herb-partitioned moxibustion (at CV 6 and ST 25) regulates NLRP3 remains unclear. In this study, we treated Crohn's disease rats with herb-partitioned moxibustion (at CV 6 and ST 25) to investigate the mechanism by which Herb-partitioned moxibustion regulates the colonic NLRP3 inflammasome by observing colon length, the colon macroscopic damage indexes, and the expression of ATP, P2X7R, Pannexin-1, NF-κBp65, NLRP3, ASC, caspase-1, IL-1ß and IL-18 in the colon in Crohn's disease. Here, this study shows that herb-partitioned moxibustion (at CV 6 and ST 25) can reduce colon macroscopic damage indexes and colon histopathological scores, alleviate colon shortening and block the abnormal activation of the NLRP3 inflammasome by inhibiting the ATP content and the expression of P2X7R, Pannexin-1 and NF-κBp65, thereby reducing the release of the downstream inflammatory cytokine IL-1ß and ultimately suppressing colonic inflammation in Crohn's disease rats. This study for the first time identifies the mechanism by which herb-partitioned moxibustion (at CV 6 and ST 25) may inhibit the abnormal activation of the NLRP3 inflammasome by inhibiting the P2X7R-Pannexin-1 signaling pathway in Crohn's disease rats.

PURPOSE: The purpose of this study was to explore the central analgesia mechanism of moxibustion for chronic inflammatory visceral pain (CIVP). METHODS: A CIVP rat model was established by 2,4,6-trinitrobenzene sulfonic acid (TNBS) plus 50% ethanol via enema. The analgesic effect of moxibustion was evaluated using the abdominal withdrawal reflex (AWR), mechanical withdrawal threshold (MWT), and thermal withdrawal latency (TWL). The expression profile of phosphorylated proteins of the mitogen-activated protein kinase (MAPK) signaling pathway in the spinal cord was assayed by protein microarray. The differentially expressed proteins were examined by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) for functional clusters and corresponding signaling pathways. RESULTS: Moxibustion exerted a significant analgesic effect for CIVP rats, mainly presenting as a decrease in the AWR score (all P<0.01) under different levels of distending pressure and an increase in MWT and TWL thresholds (all P<0.05). Compared with the normal group, 76 proteins were upregulated while 15 were downregulated, and MAPK signaling pathway was activated in the model group. Compared with the model group, there were 53 downregulated and 38 upregulated proteins in the moxibustion group, and MAPK signaling pathway was inhibited. Fold change (FC)>1.3 or <0.77 was taken as the screening standard to define the differentially expressed proteins. Fifteen differentially expressed proteins upregulated in the model group were downregulated in the moxibustion group. GO analysis showed that the differentially expressed proteins mainly controlled cellular metabolism regulation, transportation, and stress reactions. KEGG analysis revealed that these differentially expressed proteins were mostly involved in the ERK, JNK, and p38 pathways, and the ERK pathway was predominant. CONCLUSION: Moxibustion mitigates CIVP in rats and inhibits the phosphorylation of proteins in the spinal MAPK signaling pathway. The analgesic effect of moxibustion may be associated with the regulation of the spinal MAPK signaling pathway.
RESUMEN
OBJECTIVE: To design a blood ordering schedule and explore the influencing factors of blood utilizing and ordering for tumor surgical patients. METHODS: For a total of 58 306 tumor surgical patients, 22 643 applications of blood ordering and 7430 person-times of blood utilization from October 2002 to May 2012 were retrospectively analyzed at Cancer Hospital of Chinese Academy of Medical Sciences. Their clinical profiles and test results were analyzed. RESULTS: The operative transfusion rate was 32.81%. According to the operation position and the blood transfusion and preparation data, the surgical blood ordering schedule of tumor patients was established. Patient gender, hemoglobin, hematocrit, platelet, total protein and albumin level test results had significant effect on the transfusion of red blood cells (OR = 0.797, 9.614, 1.949, 0.437,0.444, 2.038, all P < 0.05). Patient gender, hemoglobin, hematocrit, activated partial thromboplastin time, prothrombin time, albumin and total protein level test results had significant effect on the transfusion of plasma (OR = 0.851, 1.367, 1.801, 1.652, 2.922, 2.224, 1.362, all P < 0.05) . CONCLUSION: For surgical tumor patients, blood ordering should be based upon the test results of routine blood, blood coagulation and protein level test results to ensure that blood transfusion is both rational and safe.

RESUMEN
OBJECTIVE: To explore the influencing factors of platelet transfusion effects in cancer patients. METHODS: A total of 363 cases of cancer patients undergoing platelet transfusion at our hospital from January 1, 2010 to June 30, 2011 were enrolled. Only one transfusion was randomly selected for each patient for single-factor analysis. Then a binary Logistic regression analysis was performed with transfusion effects as a dependent variable and the variables with P ≤ 0.2 as covariates in single-factor analysis. RESULTS: Among them, there were 280 effective and 83 ineffective transfusions with an overall effective rate of 77.1%. The single-factor analysis revealed that the P values were < 0.05 for age, platelet transfusion history, fever and antibiotic. Logistic analysis of multiple variables showed that platelet transfusion history (1-4 times compared to none, OR = 1.969,95%CI: 1.135 - 3.417; ≥ 5 times compared to none, OR = 5.260,95% CI:2.344 - 11.806), antibiotic (OR = 2.020,95%CI: 1.139 - 3.583), fever(OR = 1.789,95%CI: 1.015 - 3.153) and storage days of platelets (OR = 1.559,95%CI: 1.112 - 2.186) were independent risk factors. CONCLUSIONS: Influenced by multiple factors, the effects of platelet transfusion may be improved through reducing unreasonable transfusions, using fewer storage days of platelets and avoiding transfusions during fever and antibiotic uses.

OBJECTIVE: To detect the changes of biochemical markers in the semen of premature ejaculation patients and investigate the correlation of the markers with premature ejaculation. METHODS: Fifty-six premature ejaculation patients and 60 males with normal sexual behavior were enrolled in this experiment. Acid phosphatase, alpha- glucosidase and fructose were assayed by the methods of glucose oxidase, disodium phenyl phosphate and disodium phenyl phosphate respectively. RESULTS: The contents of acid phosphatase, alpha-glucosidase and fructose were (36.37 +/- 31.33) U/ml, (39.97 +/- 22. 09) U/ml and (3.40 +/- 1.92) mg/ml in the premature ejaculation patients and (54. 27 +/- 20. 96) U/ml, (55.71 +/- 16.19) U/ml and (2.55 +/- 1.12) mg/ml in the normal control, respectively, with significant differences in the former two markers between the two groups. The rate of the abnormal content of both acid phosphatase and alpha- glucosidase was 31% and 13% (P < 0.05) , while that of the normal content of the three markers was 10% and 33% in premature ejaculation group and the control, respectively (P < 0. 05 ). CONCLUSION: The abnormality of both acid phosphatase and alpha-glucosidase is one of the causes of premature ejaculation. Because acid phosphatase and alpha- glucosidase reflect the functions of the prostate and epididymis, we should pay attention to the status of these two organs in the treatment of premature ejaculation.
