Aim To study the inhibitory effects of gambogenic acid in combination with miR-218 on cervical cancer HeLa cells and its mechanisms.Methods Eukaryotic expression vector of miR-218(pmi8-218) was transfected into HeLa cells.Transcript levels of miR-218 were quantified by real-time quantitative PCR.HeLa cells were incubated with different concentrations of gambogenic acid alone or in combination with pmiR-218.The cell growth inhibiting ratio of HeLa cells was assessed by MTT assay.Cell apoptosis was measured by fluorescence activated cell sorting.The expression levels of Bcl-2, Bax and E-cadherin were measured by Western blot and qRT-PCR.Results Levels of miR-218 transcript significantly increased in pmiR-218 transfected HeLa cells.Overexpression of miR-218 may enhance the sensitivity of HeLa cells to gambogenic acid.Over expression of miR-218 could enhance the effect of gambogenic acid on inhibition cell proliferation, promoting apoptosis of HeLa cells.pmiR-218 could enhance the regulation of Bax expression and decrease the expression of Bcl-2 in HeLa cells.Conclusions Over expression of miR-218 may enhance the sensitivity of HeLa cells to gambogenic acid;miR-218 can enhance the effect of gambogenic acid on inhibition cell proliferation and promote the apoptosis of HeLa cells, and the mechanism may be related to down-regulation of Bcl-2/Bax expression.

Objective To summarize key points of nursing patients with cosmetic dermatitis during patch test.Method One hundred and forty one patients with contact dermatitis induced by cosmetics underwent patch test and the nursing care was performed. Results The top five allergens based on the positive rate ranked in descending order were potassium dichromate(43?97%),nickel sulfate (43?26%),cobalt chloride(36?17%),mixture of hydroxy benzoic acid(23?40%)and fragrance mix(20?57%).The positive suspicious cosmetics ranked in ascending order included body spray(80?00%),freckle cream(56?00%),liquid products(38?89%),cleaning supplies (31?58%)and skin care cream(25?62%).Conclusion During the cosmetic patch test for the patients with contact dermatitis,the nurses should conduct mental care,carefully observe the patients and make instructions to them on cosmetic health knowledge.

Objective To explore the curative effect of 308 nm excimer laser on child vitiligo and nursing measures. Method Fourty-eight children with vitiligo were treated with 308 nm excimer laser and nursed with targeted psychological treatment, skin and diet nursing.Result After treatment,6 of them got recovered(12.5%),24 remarkably improved(50%),15 slightly improved(31.2%)and 3 ineffectively treated(6.2%).Conclusions 308 nm excimer laser is effective for the treatment of child vitiligo.High quality nursing can ensure and improve the efficiency of the 308 nm excimer laser.

Objective To summarize the experience in nursing patients undergoing skin biopsy on head and face . Method One hundred and twenty patients with head facial dermatosis undergoing skin tissue biopsy were nursed from August 2012 to October 2013. Result All operation for biopsy were completed smoothly, with the cure rate at the first phase 100.0%, healing time 5~7 days, averaged (7.0 ± 3.0)d and no complications. Conclusion For those patients having undergone facial skin tissue biopsy, the nursing measures like psychological nursing, health education before operation, preoperative relief of mental disorder, postoperative wound nursing and health education, prevention of complications are critical for their recovery.

OBJECTIVETo explore the effect of mitochondrial DNA (mtDNA) deletion on the growth and invasiveness of human lymphoma Namalwa cells.

METHODSρ(0)-Namalwa cells with mtDNA deletion were generated by treating Namalwa cells with ethidium bromide and confirmed by selective ρ(0) test medium analysis, PCR and Western blotting. The growth of ρ(0)-Namalwa cells was evaluated by MTT assay and cell cycle analysis, and the cell migration and invasiveness were assessed with Transwell assay. Reactive oxygen species (ROS) production and cytosolic Ca(2+) were detected by flow cytometry.

RESULTSρ(0)-Namalwa cells could grow and divide normally in selective medium supplemented with uridine and pyruvate but not in nonselective medium. PCR did not yield the products of mtDNA, nor was COXII expression detected in ρ(0)-Namalwa cells. ρ(0)-Namalwa cells showed an obvious attenuation of cell proliferation and migration abilities with significantly lowered ROS production and cytosolic Ca(2+).

CONCLUSIONThe suppressed growth and migration of ρ(0)-Namalwa cells may be the result of decreased ROS production and cytosolic Ca(2+).

Objective To investigate the therapeutic effect of oral viaminate(a vitamine A acid derivative)on acne and its effect on the expression of androgen receptor.Methods Two hundred and eigh-teen patients with acne were allocated to treatment group and control group at random:treatment group was treated by oral viaminate;control group was treated by oral minocycline.The treatment lasted for four weeks.The effect of viaminate on the expression of androgen receptor was studied in COLO-16cells in vitro by using Northern blot or Western blot.Results The therapeutic effect of oral viaminate in treatment group was higher than that in control group(P

Objective To evaluate the effect of isokinetic muscle training combined with semiconductor laser on acute knee osteoarthritis (KOA). Methods Ninety-eight KOA patients were randomly divided into 4 groups. All patients were treated with conventional rehabilitation treatment and nursing. Based on that treatment, the group 1 received semiconductor laser irradiation, the group 2 received isokinetic muscle training, and the group 3 received laser irradiation combined with isokinetic muscle training. All patients were assessed with WOMAC osteoarthritis rating scale and affected knee extensor and flexor muscles strength measurement including peak torque, peak work, average power, average work and flex/extend before and 4 weeks after the treatment. Results All of the four treatments can significantly alleviate the condition of acute KOA patients and improve the muscle condition around the ipsilateral knee joint. The isokinetic muscle training improves the knee function of KOA patients better than the laser irradiation treatment. Isokinetic strength training combined with laser irradiation can get the most significant improvement of knee joint pain, stiffness, dysfunction, muscle strength of flexors and extensors in KOA patients. Conclusions The combination of isokinetic muscle training and semiconductor laser irradiation has a significant effect on relieving pain, reducing the stiffness, improving the function of knee of the patients with KOA in the acute phase and improving the muscle strength of the affected lower extremities. That methad is superior to drug therapy, physical therapy, or exercise alone, and is better to solve the problem of relieving symptoms and enhancing function simultaneously.
