Objective To investigate the Shenmai injection for the inhibition of hepatic and renal toxicity and leukocyte disorder during chemoradiotherapy in the women with advanced breast cancer. Methods 58 cases of female breast cancer patients with stage Ⅳ were selected and randomly divided into 2 groups, 29 cases of each group, and patients were treated with 5-hydroxytryptamine (5-HT3) receptor antagonists and white blood cell growth hormone and other conventional therapy, the control group received gemcitabine plus cisplatin chemotherapy, 28d for 1 cycles, the treatment group received more with Shenmai injection, interval was 15d, 2 groups were treated for 3 cycles. Levels of peripheral blood T lymphocyte subsets, cytokine levels and liver and kidney function, quality of life and clinical efficacy were compared. Results Compared with before treatment, levels of CD3+, CD4+ and CD4+/CD8+ in control group decreased (P<0.05), levels of CD3+, CD4+ and CD4+/CD8+ in treatment group increased (P<0.05), levels of CD8+ decreased(P<0.05), levels of IFN-γ, IL-2 and TNF-α increased(P<0.05), levels of IL-6 decreased(P<0.05), scores of KPS increased(P<0.05), scores of FACT-B decreased(P<0.05), levels of ALT, AST, BUN increased(P<0.05), and levels of CCr, WBC counts decreased(P<0.05), and compared with the control group, levels of CD3+ , CD4+ and CD4+/CD8+ in the treatment group were higher(P<0.05), levels of CD8+ were lower(P<0.05), levels of IFN-γ, IL-2 and TNF-α were higher(P<0.05), levels of IL-6 were lower(P<0.05), and the total efficiency was higher(P<0.05), levels of ALT, AST, BUN were lower (P<0.05), and levels of CCr, WBC counts were higher (P<0.05). After treatment, the efficacy of treatment group was higher than that of control group(Z=-2.142,P=0.032<0.05). Conclusion Shenmai injection can improve the efficacy of radiotherapy and chemotherapy in patients with advanced breast cancer, and it can effectively inhibit the liver and kidney damage and leukocyte disorder.

Purpose To investigate the effect of resveratrol on acute lung injury induced by lipopolysaccharide (LPS) in mice.Methods Acute lung injury (ALI) was induced by LPS in mice. The changes of lung airway inspiratory resistance (Ri), expiratory resistance (Re), and dynamic lung compliance (Cdyn) were observed with pulmonary function test apparatus. Brochoalveolar lavage fluid (BALF) was collected, and the concentrations of interleukin 1β (IL-1β)、interleukin 6 (IL-6) and tumor necrosis factory α (TNF-α) were measured by ELISA. The ratio of wet to dry weight was calculated to assess lung edema. Pulmonary vascular permeability was examined with injection Evans blue to judge the destructive extent of alveolar epithelial cell and endothelial. Pathological section was made, and the histopathological change was observed with light microscope.Results Resveratrol can inhibit the elevation of Ri and Re, and the descent of Cdyn. Simultaneously, resveratrol reduced the concentration of IL-1β, IL-6 and TNF-α,as well as the wet to dry weight ratio and the pulmonary vascular permeability significantly. Furthermore, it also could attenuate the lung injury on histopathology.Conclusion The results show that pretreatment with resveratrol has a protective effect on ALI induced by LPS. The ultimate inhibiting and release of inflammatory factors were involved in the mechanism of the effects.

Objective: To investigate whether grain-sized moxibustion at Xinshu (BL15) and Shenshu (BL23) can alleviate cognitive decline and other pathologic features in early-stage Alzheimer disease (AD) using transgenic mice with 5 familial AD mutations (5XFAD). Methods: The genotype of transgenic mice was detected by polymerase chain reaction. A total of 40 transgenic mice (1.5 months old) were randomly and equally allocated to an AD model group (5XFAD group) or a grain-sized moxibustion group (5XFAD + GM group), with 20 wild-type (WT) mice (C57BL/6J) serving as the normal control group (WT group). Mice in the 5XFAD + GM group were treated by grain-sized moxibustion at bilateral Xinshu (BL15) and Shenshu (BL23). Mice in the WT group and 5XFAD group received no treatment but were restrained to ensure exposure to a similar experimental condition. Cognitive function and memory were assessed with the Morris water maze and Y-maze tests. The amyloid β 40 (Aβ40) and amyloid β 42 (Aβ42) levels in the brain were evaluated by enzyme-linked immunosorbent assay; amyloid plaque deposition in brain tissue sections was detected by thioflavin-S staining; the expression of glial fibrillary acidic protein (GFAP), cluster of differentiation 11b (CD11b), brain-derived neurotrophic factor (BDNF), and choline acetyltransferase (ChAT) in the hippocampus and prefrontal cortex was analyzed by immunohistochemistry. Results: In the Morris water maze test, compared with the 5XFAD group, mice in the 5XFAD + GM group had a shorter escape latency and more target area crossings and spent more time in the target quadrant (P<0.05). In the Y-maze test, compared with the 5XFAD group, the number of training times of the 5XFAD + GM group was significantly decreased (P<0.05), together with more correct responses (P<0.05). Compared with the 5XFAD group, the levels of Aβ40 and Aβ42 in the brain tissue of the 5XFAD + GM group were significantly lower (P<0.05); in the hippocampus and prefrontal cortex, the total number of amyloid β plaque deposition were significantly lower (P<0.05); the expression levels of GFAP and CD11b were significantly reduced (P<0.05); and the expression levels of ChAT and BDNF were significantly increased (P<0.05).Conclusion: Grain-sized moxibustion at Xinshu (BL15) and Shenshu (BL23) greatly improves learning and memory functions, decreases the levels of Aβ40 and Aβ42, inhibits amyloid β plaque deposition, decreases the expression of GFAP and CD11b, and increases the expression of ChAT and BDNF in AD mice to inhibit the progression of AD.

Objective To explore the value of dynamic nomogram constructed by multi spiral computed tomography(MSCT)features combined with inflammatory indicators in predicting the status of microvascular invasion(MVI)of hepatocellular carcinoma(HCC)before surgery.Methods The clinical and imaging data of 137 patients with postoperative pathologically confirmed HCC were analyzed retrospectively.According to the status of the MVI,they were divided into positive group(44 cases)and negative group(93 cases).Multivariate logistic regression analysis was used to screen independent risk factors for predicting the MVI status of HCC patients,and a joint prediction model was constructed,which was displayed in the form of a dynamic nomogram.The receiver operating characteristic(ROC)curve,calibration curve and Hosmer-Lemeshow test were used to evaluate the diagnostic efficiency,calibration and goodness of fit of the model,Akaike information criterion(AIC)and Bayesian information criterion(BIC)were used for comparison between the models,and a 5-fold cross-validation and decision curve analysis(DCA)were also used to evaluate the stability and clinical applicability of the model.Results Multivariate logistic regression analysis showed that necrosis and delayed-phase enhancement(DEd),and alkaline phosphatase to lymphocyte ratio(ALR)were independent risk factors for predicting MVI status in HCC patients.The area under the curve(AUC)of the dynamic nomogram was 0.721,with the sensitivity of 0.705 and the specificity of 0.656.The AIC and BIC values were 152.372 and 158.212,respectively.The calibration curve and the Hosmer-Lemeshow test showed that the model had a high degree of calibration and goodness of fit(χ2=2.372,P=0.967),the average AUC of the 5-fold cross-validation was 0.787,and the DCA showed that the nomogram model had a good clinical applicability.Conclusion The dynamic nomogram model constructed by MSCT features combined with inflammatory indicators is feasible to predict the MVI status of HCC patients before surgery,and the dynamic nomogram can directly generate the prediction results of different individuals.
