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 study the antitumor effect of toremifene on MCF7 cell lines,and investigate the role of mitogen-activated protein kinase pathway. Methods Inhibitory effect of toremifene alone or combined with MEK inhibitor PD98059 on MCF7 cells was measured by SRB test,and that on phosphorylated ERK was detected by Western blotting.Results Toremifene exhibited a concentration-dependent inhibitory effect on the activity of MCF7 cells.Phosphorylated ERK was significantly inhibited by 5,10 and 20 mmol/L toremifene.Combined with PD98059,toremifene had a significantly enhanced cytotoxity effect,which exceeded that of application alone. Conclusion Mitogen-activated protein kinase pathway may play an important role in the antitumor effect of toremifene which is independent of estrogens.Combined with PD98059,the antitumor effect of toremifene can be reinforced,indicating a synergistic effect of these two drugs.

A safe and effective anesthesia technique is necessary in ensuring a successful surgical operation in rabbit experiments.A variety of anesthesiamethod have been reported, yet, no one matured and widely accepted anesthesiamethod is available so far.This article aims to provide an information basis for further research on general anesthesia in rabbits by reviewing the literature on single and combined anesthesia techniques in rabbits reported in the last decade.

Objective To evaluate the efficacy and safety of infliximab plus methotrexate combination therpy in Chinese with rheumatoid arthritis patients.Methods This was a double-blind placebo-controlled phaseⅢclinical trial,173 patients who had active rheumatoid arthritis were randomised to placebo(n=86)or infliximab(n=87)group on a background of a stable dosage of methotrexate.Patients were assessed at weeks 0,2,6,14 and 18.Results At week 2,the American College of Rheumatology(20)response criteria,which represent a 20% improvement from baseline,the same results with swollen joint count,tender joint count,du- ration of morning stiffness,VAS score,CRP,ESR were achieved in 52.9% of patients,compared with 14.0% of patients receiving placebo plus methotrexate.A 20% improvement was achieved in 75.9% of infliximab plus methotrexate at week 18,compared with 48.8% of patients on placebo plus methotrexate(P=0.0003).A 50% improvement was achieved in 43.7% of infliximab plus methotrexate at week 18,compared with 25.6% of pa- tients on placebo plus methotrexate(P=0.011).Infliximab was well-tolerated;withdrawals for adverse events as well as the occurrence of serious adverse events or serious infections were similar to those in the placebo group.There was only one case of tuberculosis in the treatment group.Conclusion Treatment with infliximab plus methotrexate is more effective than methotrexate alone in patients with active rheumatoid arthritis.It has rapid onset of effect and the efficacy is persistent.

OBJECTIVETo discuss the clinical effects and superiority of applying external fixation and bone transport to treat osteomyelitis and bone defect of femoral bone.

METHODSFrom August 2008 to December 2013,16 patients with osteomyelitis and bone defect of femoral bone were treated including 11 males and 5 females with an average age of 42 years old ranging from 13 to 62 years old. The average course of disease was 18 months ranging from 2 months to 4.5 years, and the average length of bone defect was 7.8 cm ranging from 4.5 to 15 cm. The bone defect of all cases were treated by external fixation and bone transport, the bone transport began at 1 week after operation, 1 mm per day and 4 times per day.

RESULTSAll patients were followed up for 10 to 36 months (means 22.5 months). One patient did not cooperate with treatment leads to the failure, then took the amputation. The remaining 15 cases of osteomyelitis were under control, including 12 cases of bone transport achieved one stage bone union, 3 cases achieved bone union via bone graft from iliac bone. The bone union time was 5 to 13 months(means 7.9 months). Thirteen patients almost obtained the same length of two lower extremities,2 patients had shortening of 1.5 to 2 cm. The time of moving the external fixation was from 6 to 16 months (means 9.3 months).

CONCLUSIONApplication of external fixation and bone transport is an effective method in treating the osteomyelitis and bone defect that can control the infection, eradicate wounds, and be the equalization of limb length.

AIM: To identify the non-steroid transcription factors upregulating the expression of L-plastin in hormone-independent prostate cancer, and partly elucidate the mechanism of hormone-refractory prostate cancer. METHODS: TF SEARCH software was used to analysis the possible binding sites of transcription factors in the 3’ end of L-plastin promoter that had been identified as important part of regulation response elements. Gel shift assay and supershift assay were used to confirm the transcription factors binding the speculated response elements. PCR site-mutagenesis technique was performed to delete the binding site of transcription factor and luciferase activity assay was carried out after deletion of the binding site. RESULTS: SP-1 respond element GGTGGGGCGGGGA located at -54- -41 of L-plastin promoter was identified with the TF SEARCH software. Gel shift assay and supershift assay confirmed that SP-1 was the transcription factor binding to GGTGGGGCGGGGA. Mutant deleted the SP-1 binding-site had low-luciferase activity than that of the naive. CONCLUSION: SP-1 plays an important role in the up-regulation of L-plastin expression in hormone-independent prostate cancer.
