Objective:To explore the clinical regularities in acupuncture-moxibustion treatment of cancer pain by reviewing the relevant studies published between 1985 and 2017.Methods:Based on the Chinese Medicine Acupuncture-moxibustion Information Database,quantitative analysis,correlation analysis and Chi-square test were applied to analyze the commonly used acupoints,meridian affiliations and body region distributions,commonly used methods and acupoint correlations,treatment method correlations,the efficacy of acupuncture-moxibustion plus the three-step analgesic ladder for cancer pain,and indicators.Results:Zusanli (ST 36),Ashi point and Sanyinjiao (SP 6) ranked the top on the list of frequency;points from Bladder Meridian of Foot Taiyang and Stomach Meridian of Foot Yangming were often used;points from the lower limbs and back had high frequencies.The most commonly used treatment method was acupuncture-moxibustion plus medication.Acupuncture-moxibustion plus the three-step analgesic ladder showed certain advantage compared with the two methods used separately,and among the integrated methods,acupoint application plus the three-step analgesic ladder produced the most significant efficacy.It took (44.77±55.54) min for the analgesic effect to act and the effect lasted for (12.81±14.59) h.Numerical rating scale (NRS),visual analog scale (VAS) and Karnofsky performance status (KPS) scores all showed significant changes after interventions (all P＜0.01);there was no significant change in the score of quality of life (QOL) after interventions (P＞0.05).Conclusion:Zusanli (ST 36),Ashi point and Sanyinjiao (SP 6) are commonly selected in acupuncture-moxibustion treatment of cancer pain;acupuncture and acupoint application are often used;acupuncture-moxibustion plus the three-step analgesic ladder can boost the treatment efficacy.

Objective To investigate the mechanism of IL-17, the signature cytokine produced by Th17 cells, in OLP lesion. Methods 24 patients with reticular OLP, 19 patients with atrophic-erosive OLP and 13 healthy volunteers were enrolled in this study . Real-time quantitative PCR ( real-time qPCR ) was performed to analyze the expressions of the production of IL-17 and CCL20 mRNA. Results The expressions of IL-17 mRNA in reticular OLP and atrophic-erosive OLP were significant higher than that in healthy oral mucosa (P = 0.0095, P <0.0001, respectively), meanwhile, remarkable increased IL-17 expression in atrophic-erosive OLP group was found compared with reticular OLP group (P = 0.0012). Additionally, the expressions of CCL20 mRNA in reticular OLP and atrophic-erosive OLP were significant higher than that in control group (P=0.0357, P<0.0001, respectively), meanwhile, CCL20 expression in atrophic-erosive OLP was higher than that in reticular OLP. The expressions of CCL20 mRNA rises with the increased expression of IL-17, and were positive correlated with IL-17 expressions in OLP lesions (P=0.003). Conclusions IL-17 production can induce chemokine CCL20 expression in OLP lesion. The signal pathway may promote the migration and infiltration of inflammatory cells in OLP lesions.

The total positive percentage of CK-20 mRNA is 43 8% in 32 colorectal cancer patients; The positive percentage of CK-20 mRNA in patients at Dukes A and B is 23 5% and 6 7% in Dukes C, D patients CONCLUSION: It is a specific, sensitive and no damage method to detect the CK-20 target gene in patients with colorectal cancer. It is helpful for early diagnosis of tumor micrometastasis and for direction of chemotherapy.

Objective To determine the molecular mechanism of berberine (BBR) inhibiting the metastasis and invasion of nasopharyngeal carcinoma 5-8F cells, and identify whether berberine suppresses the tumor-invasive action through inhibiting Ezrin or phosphate-Ezrin. Methods The non-cytotoxic concentration of berberine was detected by MTT assay. Filopodia formation of 5-8F cells was observed by electron microscope. The invasion and motility of 5-8F cells with berberine treatment were measured with Trans-well assay. Western blot was used to investigate the Ezrin and phos-Ezrin expression in 5-8F cells treated by berberine. pcDNA3.1-Ezrin and pcDNA3.1-Ezrin M were transfected into 6-10B cells. The inhibitory effect of berberine on the motility and invasion of 6-10B-pcDNA3.1-Ezrin and 6-10B-pcDNA3.1-Ezrin M was detected, respectively. Results Berberine non-cytotoxic concentration was 0-40 μmol/L. After being treated by berberine, filopodia of 5-8F cells obviously reduced, and the permeating artificial basement membrane cells largely decreased in both time- and concentration-dependent manner. There was significant difference compared with the control group (P<0.05). Berberine suppressed the phos-Ezrin expression of 5-8F cells in both time- and concentration-dependent manner (P<0.05), but the effect of berberine was weaker on 6-10B-pcDNA3.1-Ezrin M than on 6-10B-pcDNA3.1-Ezrin. Conclusion Berberine inhibits nasopharyngeal carcinoma cell invasion through inhibiting phos-Ezrin expression and filopodia formation.

Objective To investigate the effects of dietary consumption of monounsaturated fatty acid (MUFA) on the control of type 2 diabetes mellitus. Methods One hundred and eighty-five patients with type 2 diabetes mellitus from a community in Shanghai were randomly divided into MUFA intervention group (MUFA group,n=125) and control group (n=60). The patients in MUFA group consumed tea oil enriched in MUFA for 3 months,while those in control group consumed normal oil. The serum glucose (fasting plasma glucose and 2-hour postprandial glucose),fasting insulin and blood lipid were examined before intervention and three months after intervention,and the parameters were compared within groups and between groups. Results The serum fasting glucose,fasting insulin,total cholesterol and low density lipoprotein-cholesterol 3 months after intervention were significantly lower than those before intervention in MUFA group (P0.05),while the serum fasting glucose,total cholesterol and low density lipoprotein-cholesterol in MUFA group were significantly lower than those in control group 3 months after intervention (P0.05). Conclusion Dietary consumption of MUFA can improve the glucose and lipid metabolism in patients with type 2 diabetes mellitus.

The role of serum and glucocorticoid-induced kinase 1 (SGK1) pathway in the connective tissue growth factor (CTGF) expression was investigated in cultured human mesangial cells (HMCs) under high glucose. By using RT-PCR and Western blot, the effect of SGK1 on the CTGF expression in HMCs under high glucose was examined. Overexpression of active SGK1 in HMCs transfected with pIRES2-EGFP-S422D hSGK1 (SD) could increase the expression of phosphorylated SGK1 and CTGF as compared with HMCs groups transfected with pIRES2-EGFP (FP) under high glucose or normal glucose. Overexpression of inactive SGK1 in HMCs transfected with pIRES2-EGFP-K127N hSGK1 (KN) could decrease phosphorylated SGK1 and CTGF expression as compared with HMCs groups transfected with FP under high glucose. In conclusion, these results suggest that high glucose-induced CTGF expression is mediated through the active SGK1 in HMCs.
