The liver is the most common site of colorectal cancer metastasis(CRLM). The importance of how to treat CRLM has attracted attention from doctors world wide and specific academic organization and expect consensus has been established. Relative principals of treatment of CRLM also developed in China, for example, guideline of diagnosis and treatment of colorectal cancer liver metastasis(draft) and standard for diagnosis and treatment of colorectal cancer, which were established in 2008 and 2010, respectively. However, we found that the Chinese doctors still understand these treatment policies inadequately, and easily produce deviation on the treatment progress. Based on the problems of current CRLM treatment, we have some thoughts or suggestions as follows: (1)Promoting the core conception of CRLM treatment actively: surgery is the only method to achieve possible cure of the CRLM. (2) Evaluating the status of new adjuvant chemotherapy for CRLM dialectically. (3)Paying attention to multi-disciplinary team(MDT): MDT is the scientific treatment foundation of CRLM. (4)Changing the treatment conception of primary tumor of CRLM: radical resection of primary tumor is essential for the resectable CRLM.(5)Emphasizing the surgical treatment of CRLM combined with lung metastasis. (6)Do not neglect the safety of patients, when we emphasize the surgery is the optimal treatment of CRLM. These guides of treatment of CRLM will improve the outcomes of CRLM around the world, but we still need pay attention to above mentioned points in order to insure the standardization and scientification of CRLM therapy.

Thereinto Diaporthe, Fusarium, Nigrospora, Alternaria, Phoma, Corynespora, Epicoccum, and Cladosporium were common genera to S. ningpoensis from six localities, but the dominant genus was different: Fusarium was the dominant genus from Anhui, Hubei, Hunan, and Shaanxi; Alternaria was the dominant genus from Sichuan; Diaporthe was the dominant genus from Zhejiang. According to the similarity coefficient, the composition of the endophytic fungi was distinctly different between six localities. The Shannon-wiener diversity index and Simpson index of endophytic fungi in S. ningpoensis from Zhejiang were found higher than others. The diversity of endophytic fungi in S. ningpoensis from Sichuan was lower than others. Conclusion: Systematic studying the diversity and community structure of endophytic fungi in S. ningpoensis and clarifying their distribution regularity in plant tissues can offer basic data and scientific basis for their development and utilization.

Objective To verify the synergistic effect of transferrin modified β-elemene and celastrol co-loaded microemulsion (Tf-EC-MEs) on anti-colorectal cancer treatment. Methods The optimal mass ratio of β-elemene and celastrol to growth inhibition of Lovo and HT-29 colorectal cancer cells was optimized by MTT staining method in vitro. Tf-EC-MEs was prepared by “mixing-dripping” method, and the preparation and physicochemical properties of the particles were characterized by high performance liquid chromatography (HPLC), laser particle analyzer, and transmission electron microscope. The MTT staining, HPLC-BCA combined method, and Annexin V-PE/7-Aminoactinomycin D (Annexin V-PE/7-AAD) kit were used to investigate the antitumor activity of Tf-EC-MEs in vitro, and its effect on cell uptake, and apoptosis of tumor cells. The tumor-bearing nude mice model was established by subcutaneous injection of Lovo cells, and the tumor growth, weight, and survival time were observed after intravenous injection of β-elemene + celastrol, β-elemene-celastrol co-loaded microemulsion (EC-MEs), and Tf-EC-MEs. Results The combined administration of β-elemene and celastrol (40:1) had significant synergistic effect on the anti-colorectal cancer of Lovo and HT-29 cells. IC50 of β-elemene + celastrol in Lovo and HT-29 cells were (17.5 ± 2.9) and (36.4 ± 3.6) μg/mL, with the CI as 0.89 and 0.96, respectively. IC50 of Tf-EC-MEs in Lovo and HT-29 cells were (11.7 ± 0.6) and (27.4 ± 1.2) μg/mL, with the CI as 0.61 and 0.72 respectively. The 4 h of Lovo uptake of Tf-EC-MEs was 7.2 μg/mg, which was 3.3 times higher than that of β-elemene + celastrol. Tf-EC-MEs induced apoptosis in 59.2% of Lovo cells, which was significantly higher than that in beta-elemene + celastrol and EC-MEs groups. Tf-EC-MEs showed the overwhelming inhibition of growth of Lovo tumor-bearing tumors. The survival rate of Tf-EC-MEs-treated mice was 37.5% at day 60. In Tf-EC-MEs treated group, HE staining sections of tumor tissues showed substantial cell necrosis and the Ki-67 immunohistochemical sections displayed the significant inhibition of proliferation of tumor cells. Conclusion Compared with the combination group (beta-elemene and celastrol) and EC-MEs groups, Tf-EC-MEs has a promising potential in the synergistic anti-colorectal cancer treatment.

ObjectiveTo compare the efficacies between heat-sensitive moxibustion and warm needling in treating cervical spondylosis of vertebroarterial type.MethodTotally 120 patients with cervical spondylosis of vertebroarterial type were randomized into a heat-sensitive moxibustion group and a warm needling group, 60 in each group. In addition to acupuncture at bilateral Fengchi (GB20), Wangu (GB12), Tianzhu (BL10), Dazhui (GV14) and Baihui (GV20), the heat-sensitive moxibustion group was given mild moxibustion to the heat-sensitive points in cervical and scapular regions, while the warm needling group was given regular moxibustion.ResultGenerally, after 20 treatment sessions, efficacy wasfound in both groups, and there were significant differences in both groups after intervention (P<0.05), while the improvements of integral score, dizziness, cervical and shoulder pain, and the recovery and markedly-effective rate in the heat-sensitive moxibustion group were significantlysuperiorto that in the warm needling group (P<0.05).ConclusionCompared to warm needling treatment, heat-sensitive moxibustion can more significantly improve dizziness and pain in patients with cervical spondylosis of vertebroarterial type, and thus enhance the therapeutic efficacy.
