ABSTRACT
OBJECTIVE@#To observe the effect of moxibustion on skin lesions and immune inflammatory response in psoriasis mice, and to explore the possible mechanism of moxibustion for psoriasis.@*METHODS@#A total of 32 male BALB/c mice were randomly divided into a normal group, a model group, a moxibustion group and a medication group, 8 mice in each group. Psoriasis model was induced by applying 5% imiquimod cream on the back for 7 days in the model group, the moxibustion group and the medication group. At the same time of model establishment, the moxibustion group was treated with suspension moxibustion on skin lesions on the back, 20 min each time, once a day; the medication group was treated with 1 mg/kg methotrexate tablet solution by gavage, once a day. Both groups were intervened for 7 days. The daily changes of skin lesions were observed, and the psoriasis area and severity index (PASI) score was evaluated; the histopathological changes of skin lesions were observed by HE staining; the positive expression of proliferating cell nuclear antigen (PCNA) and T lymphocyte surface marker CD3 were detected by immunohistochemistry; the expression level of serum interleukin (IL) -17A was detected by ELISA, and the relative expressions of tumor necrosis factor-α (TNF-α), IL-1β and IL-6 mRNA in skin lesions were detected by real-time PCR.@*RESULTS@#The increased and hypertrophy scale, dry skin, red and swollen epidermis and obvious infiltration were observed in the model group, and each score and total score of PASI were higher than those in the normal group (P<0.01). The scale score, infiltration score, and total score of PASI in the moxibustion group were lower than those in the model group (P<0.01); the infiltration score and total score of PASI in the medication group were lower than those in the model group (P<0.01, P<0.05). The inflammatory cell infiltration in the model group was obvious, and the thickness of epidermal layer was increased compared with that in the normal group (P<0.01); the inflammatory cell infiltration and Munro micro abscess were decreased in the moxibustion group and the medication group, and the thickness of epidermal layer was decreased compared with that in the model group (P<0.01). Compared with the normal group, the positive cell number of PCNA and T was increased (P<0.01), and the body mass was decreased, and the spleen index was increased (P<0.01), and the expression of serum IL-17A and the relative expression of TNF-α, IL-1β and IL-6 mRNA in the skin lesions was increased in the model group (P<0.01). Compared with the model group, the positive cell number of PCNA and T was reduced (P<0.01), and the spleen index and the relative expression of TNF-α, IL-1β and IL-6 mRNA were reduced (P<0.01) in the moxibustion group and the medication group; the body mass of mice in the moxibustion group was higher than that in the model group (P<0.01); the content of serum IL-17A in the medication group was lower than that in the model group (P<0.01); the relative expression of TNF-α, IL-1β mRNA in the moxibustion group was higher than that in the medication group (P<0.01).@*CONCLUSION@#Moxibustion could effectively improve the scale and infiltration of skin lesions in psoriasis mice. Its mechanism may be related to inhibiting inflammatory response and regulating immunity.

OBJECTIVE@#To observe the effect of fire needling on psoriasis-like lesion and the signal transducer and activator of transcription 3 (STAT3) pathway in mice and compare the therapeutic effect between different interventions of fire needling therapy (surrounding technique of fire needling, fire needling at "Dazhui" [GV 14] and "Zusanli" [ST 36]).@*METHODS@#Thirty male BALB/c mice were randomized into a blank group, a model group, a dexamthasone group, a surrounding technique group and an acupoint group, 6 mice in each one. Except the blank group, the mice in the rest groups were established as psoriasis-like lesion model by topical application with imiquimod cream, once daily, consecutively for 8 days. From day 4 to day 8, in the dexamthasone group, gastric infusion with 0.2 mL dexamthasone was administered, once daily. On day 4, 6 and 8, in the surrounding technique group, fire needling was exerted around the skin lesion; and fire needling was applied to "Dazhui" (GV 14) and "Zusanli" (ST 36) in the acupoint group, once a day. The changes in skin lesion on the dorsal parts of mice were observed in each group to score the psoriasis area and severity index (PASI). Using HE staining, the dermal morphological changes and epidermal thickness were observed in the mice of each group. The positive expression of proliferating cell-associated antigen Ki-67 was determined by immunofluorescence. Immunohistochemistry method was used to determine the expressions of , and T cells of skin tissue in each group. Using real-time PCR, the expressions of interleukin (IL)-17, IL-22, tumor necrosis factor α(TNF-α) mRNA were determined. Western blot method was adopted to determine the protein expressions of STAT3 and p-STAT3 in skin tissue in each group.@*RESULTS@#Compared with the blank group, the scores of each item and the total scores of PASI, as well as the epidermal thickness were all increased in the mice of the model group (P<0.01). Except for the erythema scores of the dexamethasone group and the surrounding technique group, the scores of each item and the total scores of PASI, as well as the epidermal thickness were all decreased in each intervention group as compared with the model group (P<0.01). The infiltration scores and the total scores in the dexamethasone group and the acupoint group were lower than those in the surrounding technique group respectively (P<0.01, P<0.05). In comparison with the blank group, Ki-67 positive cell numbers and the numbers of , and T cells in skin tissue were increased in the mice of the model group (P<0.01). Ki-67 positive cell numbers and the numbers of , and T cells were reduced in each intervention group as compared with the model group (P<0.01), and the numbers of and T cells in the acupoint group were less than the surrounding technique group (P<0.01). Compared with the blank group, the mRNA expressions of IL-17, IL-22 and TNF-α and the ratio of p-STAT3 to STAT3 were all increased in the model group (P<0.01). The mRNA expressions of IL-17, IL-22 and TNF-α and the ratio of p-STAT3 to STAT3 were all decreased in each intervention group as compared with the model group (P<0.01, P<0.05). The mRNA expressions of IL-17, IL-22 and TNF-α in the acupoint group, as well as mRNA expression of IL-17 in the surrounding technique group were all lower than the dexamethasone group (P<0.01), while, the mRNA expression of IL-22 in the acupoint group was lower than the surrounding technique group (P<0.01).@*CONCLUSION@#Fire needling therapy improves skin lesion severity in imiquimod induced psoriasis-like lesion of the mice, which is probably related to the inhibition of STAT3 pathway activation and the decrease of Th17 inflammatory factors expression. The systemic regulation of fire needling at "Dazhui" (GV 14) and "Zusanli" (ST 36) is superior to the local treatment.

RING finger protein 13 (RNF13) is a novel E3 ubiquitin ligase whose expression is associated with cancer development. However, its specific role in cancer progression and metastasis remains unclear. Here, a B16F10/LLC experimental pulmonary metastatic model was developed to examine the formation of metastatic foci in the lung. A greater number of tumor colonies were observed in the lungs of RNF13-knockout (KO) mice than in their wild-type (WT) littermates, whereas no significant differences in tumor size were observed between the two groups. In short-term experiments, the number of fluorescently-labeled B16F10 cells increased remarkably in RNF13-KO lungs at early time points, whereas clearance of tumor cells from the blood was not affected. These results indicated that RNF13 may inhibit the colonization of B16F10 cells in the lung. Assessment of the concentration of various cytokines in tumor bearing lungs and blood did not detect significant differences between the blood of RNF13-KO and WT mice; however the levels of GM-CSF were significantly reduced in RNF13-KO tumor bearing lungs, which may have guided more B16F10 cells to migrate to the lungs. This was confirmed by lower GM-CSF concentrations in conditioned media from the culture of RNF13-KO lung slices. Collectively, our results suggest that host RNF13 affects the concentration of GM-CSF in tumor-bearing lungs, leading to a reduction in the colonization of metastatic tumor cells in the lung.

RING finger protein 13 (RNF13) is a newly identified E3 ligase reported to be functionally significant in the regulation of cancer development, muscle cell growth, and neuronal development. In this study, the function of RNF13 in cardiotoxin-induced skeletal muscle regeneration was investigated using RNF13-knockout mice. RNF13(-/-) mice exhibited enhanced muscle regeneration-characterized by accelerated satellite cell proliferation-compared with wild-type mice. The expression of RNF13 was remarkably induced in macrophages rather than in the satellite cells of wild-type mice at the very early stage of muscle damage. This result indicated that inflammatory cells are important in RNF13-mediated satellite cell functions. The cytokine levels in skeletal muscles were further analyzed and showed that RNF13(-/-) mice produced greater amounts of various cytokines than wild-type mice. Among these, IL-4 and IL-6 levels significantly increased in RNF13(-/-) mice. The accelerated muscle regeneration phenotype was abrogated by inhibiting IL-4/IL-6 action in RNF13(-/-) mice with blocking antibodies. These results indicate that RNF13 deficiency promotes skeletal muscle regeneration via the effects on satellite cell niche mediated by IL-4 and IL-6.

<p><b>OBJECTIVE</b>To study the MRI-based characteristics of acute carbon monoxide poisoning (ACOP) and delayed encephalopathy after acute carbon monoxide poisoning (DECAMP), and to compare the degree of brain damage.</p><p><b>METHODS</b>A retrospective analysis was performed on the clinical and MRI data of 27 patients diagnosed with ACOP and 35 patients diagnosed with DECAMP. Ten healthy volunteers were recruited in the normal control group. All subjects received both routine MRI and diffusion-weighted MRI. Apparent diffusion coefficient (ADC) was determined with symmetric measurement of region of interest in the bilateral globus pallidus, white matter around lateral ventricle, and centrum semiovale. ADC values were compared afterwards.</p><p><b>RESULTS</b>Thirteen of the 27 ACOP cases were found of symmetrical abnormal signal in the bilateral globus pallidus, among whom 8 patients only showed pallidum region involvement, while the other 5 patients showed involvement of other regions. Eight ACOP patients showed cortical and subcortical white matter involvement, and 4 cases showed diffused abnormal signal around the bilateral ventricles and in the bilateral centrum semiovale. Two cases of ACOP presented with multiple region involvement. Thirty-five DECAMP patients showed diffused swelling and symmetric demyelination in multiple regions of the brain parenchyma. The periventricular white matter and centrum semiovale were involved in 33 cases, the deep brain nuclei were involved in 23 cases, and the cerebral cortex was involved in 3 cases. The ACOP and DECAMP groups had significantly lower ADC values in the periventricular white matter and bilateral centrum semiovale than the normal control group (P < 0.05), and the ADC values were significantly lower in the DECAMP group than in the ACOP group (P < 0.05). The ACOP group had a significantly lower ADC value in the globus pallidus than the DECAMP group and normal control group (P < 0.05); the DECAMP group had a significantly higher ADC value in the globus pallidus than the ACOP group and normal control group (P < 0.05).</p><p><b>CONCLUSION</b>Routine MRI and ADC value can evaluate the degree of brain damage in ACOP and DECAMP patients based on lesion involvement on a more microscopic scale. It can provide valuable information for therapy selection and prognostic evaluation.</p>

ABSTRACT
Purpose To analyze the relevance between magnetic susceptibility weighted imaging intratumoral susceptibility signal intensity (ITSS) and diffusion weighted imaging apparent diffusion coefficient (ADC) with different grade gliomas, and to explore the value of ITSS and ADC in the preoperative grading of gliomas. Materials and Methods Fifty-two cases of glioma patients underwent magnetic susceptibility weighted imaging and diffusion weighted imaging scans, all subjects were divided into low-grade glioma group (18 cases) and high-grade glioma group (34 cases) according to brain tumor grading standard, correlation between ITSS grade and ADC values with tumor grade was analyzed, and ROC curve was used to evaluate the diagnostic efficacy of ITSS and ADC values in the grading of brain glioma. Results Difference of ITSS grading was statistically significant (χ2=27.458, P<0.01) among different grade gliomas;difference of ADC values between different grade gliomas was also statistically significant (U=689.000, P<0.01); there was a significant positive correlation (r=0.727, P<0.001) between ITSS grading and pathological grading, ADC values were significantly negatively correlated (r=-0.622, P<0.001) with tumor grading, and ITSS grading was significantly negatively correlated (r=-0.617, P<0.001) with ADC values among different grade brain gliomas. With pathological grading as reference standard, the diagnostic sensitivity, specificity, accuracy, positive predictive value and negative predictive value of ITSS for preoperative glioma grading was 85.29%, 77.78%, 82.69%, 87.88%and 73.68%, respectively, while the diagnostic sensitivity, specificity, accuracy, positive predictive value and negative predictive value of ADC values for preoperative glioma grading was 97.06%, 88.89%, 94.23%, 94.29%and 94.12%, respectively. Conclusion There is a significant correlation between ITSS grading, ADC values and pathological grading of gliomas, the combination use of ITSS and ADC values can significantly improve the preoperative grading accuracy of brain glioma.
ABSTRACT
Single modality treatment of advanced gastrointestinal cancer has been associated with unfavorable outcomes. Radiotherapy as an important component of the combined modality therapy of gastrointestinal tract tumors may achieve down-staging, increase resection rate while preserving sphincter function, decrease local recurrence rate, and improve survival rate. Precision radiotherapy has better conformity, accuracy, and lower toxicity. Precision radiotherapy will become more and more important in the combined modality therapy of gastrointestinal tract cancer.
