Objective To investigate the effect of general nursing intervention on the mental state of the patients with breast cancer undergoing chemotherapy.Methods Forty-eight breast cancer patients undergoing postoperative chemotherapy received nursing general interventions including healthy education,psychological nursing care,pantosomatous,relaxation therapy and rehabilitative exercise. All patients were evaluated by self-rating depression scale (SDS) and depression status inventory (DSI) before and after the general intervention.Result The scores of SDS and DSI after intervention were significantly lower than those before intervention (bothP<0.05).Conclusion The general nursing intervention could significantly improve patients’ psychological state and life quality,promote rehabilitation and improve their quality of life.

Objective To explore the relationship between galactose-induced apoptosis of lens epithelial cells and cataractogenesis.Methods Galactose was injected retrobulbarly into Wistar rats.The opacity of lens was examined by slit lamp.The expression of C-MYC was measured by flow cytometer.The apoptosis of lens epithelial cells was observed by TUNEL techniques.Results More than 50 percent of lenses were in the Ⅱ stage of cataractogenesis on the(7 d) after galactose induction;Eighty-seven percent of lenses were in the Ⅳ-Ⅴ stage on the(14 d),and 100 percent of lenses were in the Ⅳ-Ⅴ stage on the(24 d).The rate of apoptotic cell on the(7 d) and on the(14 d) after galactose induction was respectively 5.6%～8.4% and 30.2%～41.8%,and 60% apoptotic cells were observed on the(24 d).The levels of C-MYC expression in lens epithelial cells induced by galactose on the(7 d) and(14 d) were higher than that of normal lenses,but the level of C-MYC expression backed to normal level on the(24 d).Conclusion It was suggested that there are some apoptosis of the lens epithelial cells during galactose-induced cataractogenesis and that the apoptosis of the lens epithelial cells might be caused by higher expression of C-MYC.

Background Various studies demonstrated that the apoptosis of lens epithelial cells(LECs) is associated with the overexpression of the c-myc gene in LECs induced by galactose.Inhibiting the abnormal expression of the c-myc gene in LECs is an effective approach to mitigate the pathogenesis and development of cataract.Objective The goal of this study is to investigate the inhibitory effects of c-myc antisense oligodeoxynucleotide(c-myc ASODN) on the apoptosis of LECs in the eye with galactose-induced cataract.Methods Galactose-induced cataract models were established by the retrobulbar injection of 0.2 mL of 20% galactose once per day.Lipo-antisense oligodeoxynucleotide(Lipo-ASODN,0.2 mL) was retrobulbarly injected 4 hours after the injection of galactose at one-day intervals.The animals were sacrificed and lenses were obtained to evaluate the apoptosis of LECs and the effect of c-myc ASODN on LECs apoptosis induced by galactose was examined by TUNEL assay after 7,14 and 24 days.The ultrastructural changes of LECs were examined under the transmission electron microscopy(TEM).Results A significant difference in the apoptotic rate of LECs was found among the 7 day,14 day and 24 day groups(F_(7 days)=3 418.495,P＜0.01;F_(14 days)=1137.555,P＜0.01;F_(24 days)=2198.871,P＜0.01).The apoptotic rate of LECs in the galactose group was markedly higher than that in the normal saline solution group 7 days,14 days and 24 days after the experiment(P＜0.01).The apoptotic rate of LECs in the galactose+lipo+ ASODN group significantly declined in comparison to the galactose group after 7 days,14 days and 24 days(P＜0.05).TUNEL assay showed the condensation,breakage and irregularity of the nuclei of apoptotic cells in the galactose group.The destruction of the ultrastructure of the cells and organelles were observed under the transmission electron microscope.Conclusion Galactose induces apoptosis of LECs in cataractogenesis.C-myc ASODN inhibits apoptosis of LECs induced by galactose.

Objective To evaluate the roles of Toll-like receptor 2 (TLR2),TLR4 and myeloid differentiation factor 88 (MyD88) in immune recognition and immune mediation in sporotrichosis by detecting their expressions in skin lesions of sporotrichosis.Methods Biopsy specimens were obtained from the skin lesions of 19 patients with sporotrichosis and normal skin of 12 healthy human controls.Immunohistochemistry was performed to observe the expressions of TLR4 and MyD88,and real-time fluorescence-based quantitative PCR to quantify the expressions of TLR2 and MyD88 mRNAs.Data were expressed as mean ± standard error.Statistical analysis was done with the SPSS17.0 software.Independent samples t-test was conducted to compare the parameters between the lesional and control specimens.A p-value of less than 0.05 was considered to be statistically significant.Results TLR4 and MyD88 were mainly observed in the whole epidermis except the stratum corneum as well as plasma cells and lymphocytes in the dermis and subcutaneous tissue in lesional skin.However,TLR4 was nearly absent and MyD88 was weakly expressed in the dermis and subcutaneous tissue in normal skin.The expression levels of TLR4 and MyD88 were significantly higher in the lesional skin than in the control skin (TLR4,63.767 ± 3.829 vs.5.167 ± 3.246,t =4.82,P ＜ 0.05; MyD88,57.236 ± 4.744 vs.10.588 ± 1.640,t =3.30,P ＜ 0.05).Similarly,the lesional skin showed significantly stronger expressions of TLR2 and MyD88 mRNAs compared with the normal skin (TLR2,1.974 ± 1.452 vs.1.430 ± 1.073,P ＜ 0.05; MyD88,2.028 ± 2.061 vs.0.688 ± 0.422,P ＜ 0.05).Conclusion Sporothrix may induce the development of sporotrichosis by interacting with host immune system via TLR signaling pathways.

Objective To investigate the therapeutic effect of Pingyangmycin combined with Triamcinolone Acetonide on the huge faciocervical lymphatic malformations (LMs) in infants.Methods Sixty-seven infants with LMs located in head and neck from January 2009 to June 2014 were retrospectively analyzed in Kunming Children's Hospital.Thirty-five males and 32 females were enrolled,aged from 1 month to 4 years,with a median age of 1.3 years.Computed tomography and ultrasonography were used to evaluate the location,size and extent of LMs before treatment in all the patients.The size of lesion varied from 5.2 cm ×7.5 cm to 9.2 cm × 10.5 cm.All patients were given local injection of Pingyangmycin combined with Triamcinolone Acetonide after puncturing fluid with uhrasonography guiding under general anesthesia.The injection was repeated every 30 d when necessary.Results The number of injections varied from 2 to 5 times,with a median number of 3.9 times.All cases were followed up for 5 to 36 months.Thirty-two cases (62.68％) were cured,improvement in 19 cases (28.36％) and no effect in 6 cases (8.96％).The total effective rate was 91.04％.There was no severe allergic reaction or pulmonary fibrosis.Secondary operation was performed after 6 months in 12 cases.Two post-operative complications were found,1 was minor paralyses of mandibular branch of facial nerve,with mouth askew,the other was trachyphonia,who were both improved after rehabilitation treatment.Conclusions In order to avoid serious complications,the huge LMs may be given local injection of Pingyangmycin combined with Triamcinolone Acetonide after puncturing fluid with ultrasonography guiding.Graded sclerotherapy provides for a less invasive and shorter course of treatment.The complications and risk of secondary resection increase slightly if sclerotherapy has no curative effect.

The distribution frequency of MICB?00502/00502 in patients with ureaplasma urealyticum was higher,but the difference was not statistically significant(Pc>0. 05). Conclusion:MIC allele gene polymorphism may be associated with ureaplasma urealyticum infection.

AIMTo establish a solid phase extraction-high performance liquid chromatographic (SPE-HPLC) method for determining plasma scutellarin concentration, and study its pharmacokinetics after i.v. breviscapine in rabbits.

METHODSMethanol-water-phosphoric acid (50:50:0.5) mixture was used as mobile phase, Nucleosil C18 column (250 mm x 4.6 mm ID) was selected. The wavelength of UV detection was 335 nm. Fifteen rabbits, randomized into 3 groups, were given breviscapine i.v. at the dose of 10, 20 and 40 mg.kg-1. Scutellarin in plasma was determined by SPE-HPLC method.

RESULTSLinearity was obtained over the range of 0.02-10.0 mg.L-1 of scutellarin. The method recovery was 96.15%-99.31%; the within-day and between-day RSDs were all below 10%. After i.v. 10, 20 and 40 mg.kg-1 of breviscapine to rabbits, the concentration-time curve of scutellarin fitted to a three compartment model. The main pharmacokinetic parameters showed no significant difference between low and medium doses, but the difference was significant between high dose and other doses.

CONCLUSIONThis assay method was accurate, sensitive, simple and suitable for the measurement of plasma scutellarin concentration. The pharmacokinetic characteristics were found to fit a three-compartment model following i.v. injection of breviscapine to rabbits. The changes of drug concentration in vivo exhibited linear kinetics ove the dosage range of 10-20 mg.kg-1, but when the dosage was 40 mg.kg-1, the linear kinetic properties disappeared.
