Objective:To investigate the effect of sorafenib on the proliferation of human oral cancer TCA8113 cells and to explore the underlying mechanisms.Methods:Mter treated with sorafenib at 2.5,5,10,20 μg/ml respectively for48 h,TCA8113 cell proliferation was examined by MTT and colony formation assay.Western blotting was employed to examine the p38MAPK expression in the cells.TCA8113 cells were pretreated with 10 μmol/L of SB203580 (a specific inhibitor of p38MAPK) for 30 min,and then by different concentrations of sorafenib for 48 h,cell proliferation was tested by MTT assay.Results:Sorafenib significantly inhibited the proliferation of TCA8113 cells in a concentration dependent fashion.Sorafenib also remarkably promoted the activation of p38MAPK of the cells.SB203580 significantly alleviated soiafenib induced TCA8113 cell viability decrease.Conclusion:Sorafenib can inhibit the proliferation of TCA8113 cells,which may be related to the activation of p38MAPK.

AIM:To investigate the effect of genistein on the proliferation of human oral cancer TCA 8113 cells and to explore the underlying mechanisms .METHODS:The cell proliferation was examined by MTT assay , cell counting and colony formation assay .Western blotting was employed to examine the protein levels of vascular endothelial growth fac -tor (VEGF), extracellular signal-regulated kinase (ERK) and p-ERK.RESULTS: Genistein significantly inhibited the proliferation of TCA8113 cells in a concentration-dependent fashion .Moreover , genistein dose-dependently decreased the protein levels of VEGF, ERK and p-ERK.The expression of VEGF was also blunted by U 0126, a specific inhibitor of ERK.U0126 and axitinib, a VEGF receptor antagonist , both significantly inhibited the proliferation of TCA 8113 cells. CONCLUSION:Genistein inhibits the proliferation of TCA8113 cells, which may be related to its inhibitory effect on ERK expression and activation , thus subsequently decreasing the expression of VEGF .

Objective To analyze Candida species causing vulvovaginal candidiasis in Qingdao and surrounding areas.Methods Vaginal discharge specimens were collected from 362 patients with suspected vulvovaginal candidiasis in the Affiliated Hospital of Qingdao University Medical College from May 2011 to November 2011,and subjected to routine fungal culture.The Candida isolates were identified by using Sabouraud dextrose agar,CHROMagar medium,germ tube test with serum,and API 20C AUX Clinical Yeast System.Results Totally,313 (86.46％) Candida strains were isolated from the specimens of 362 patients.Of these Candida strains,275 were identified as Candida albicans,38 as non-albicans Candida species,including 13 Candida glabrata strains,8 Candida parapsilosis strains,7 Candida tropicalis strains,5 Candida krusei strains,1 Candida lusitaniae strain,1 Candida dubliniensis strain,1 Rhodotorula mucilaginosa strain,1 Pichia ohmeri strain and 1 Trichosporon mucoides strain.Conclusions As far as vulvovaginal candidiasis is concerned,Candida albicans is still the most prevalent pathogen,and Candida glabrata appears to be the predominant species in pathogenic non-albicans Candida species.

Objective To observe the effect of electroacupuncture on early enteral nutrition (EEN) support in patients with severe craniocerebral injury.Methods A prospective, randomized, controlled study was conducted, 50 patients with severe craniocerebral injury admitted to the the Department of Intensive Care Unit of Traditional Chinese Medicine Hospital of Ningbo from January 2014 to October 2016 were enrolled, and they were randomly divided into electroacupuncture experimental group (26 cases) and conventional treatment control group (24 cases) by randome number table. Enteral nutrition (EN) support was implemented in 24 - 48 hours after admission for all the patients, additionally, the electroacupuncture experimental group was treated by electroacupuncture stimulating acupoint from the 1st day after admission, once 30 minutes daily for consecutive 10 days. The levels of EN calorie reaching standard situation and the parenteral nutrition (PN) necessary for addition were recorded on 3 days and 5 days after admission; the nasal feeding amount of the two groups was recorded on the 1, 4, 7 days; the incidences of complications during EN support period were observed in both groups.Results The proportion of EN calorie reaching the standard in electroacupuncture experimental group was significantly higher than that in the conventional treatment control group in 5 days of treatment [92.3% (24/26) vs. 70.8% (17/24),P < 0.05]. The proportions necessary for addition of PN support were lower in electroacupuncture experimental group than those in the conventional treatment control group on 3 days and 5 days of treatment [3 days: 19.2% (5/26) vs. 25.0% (6/24), 5 days: 7.7% (2/26) vs. 16.7% (4/24)], but there were no significant statistical differences between the two groups (bothP > 0.05). The nasal feeding amounts in electroacupuncture experimental group were significantly higher than those in the conventional treatment control group on 4 days and 7 days of treatment [4 days (mL): 1292.31±123.04 vs.1204.17±139.81,7 days (mL):1342.31±113.75 vs.1275.00±103.21, bothP < 0.05]. The incidence of complications of the electroacupuncture experimental group was significantly lower than that of the conventional treatment control group in 10 days of treatment [26.92% (7/26) vs. 41.67% (10/24),P < 0.05].Conclusions Application of electroacupuncture has a certain clinical value during implementing EN support for treatment of patients with severe craniocerebral injury, early intervention of electroacupuncture can effectively improve the patients' gastrointestinal function and elevate the successful rate of EN, and the therapy is simple, effective and safe without any obvious adverse reactions.
