Objective To explore the relation between changes in apurinic/apyrimidinic endonuclease (APE1) gene expression and effects of melphalan on multiple myeloma (MM) cells. Methods Expression of APE1 protein was detected in MM cell line KM3 using immunocytochemical staining and Western blot assay after 0~15?mol/L melphalan treatment for 1~2d. Integral optical density was determined by means of image analysis system. Results There was positive relationship between levels of APE1 protein in KM3 cells and the treatment time and dose of melphalan. Conclusion Expression of APE1 protein could be induced by melphalan treatment. The result suggests that a high expression of APE1 protein may play a certain role in the resistance of multiple myeloma to melphalan.

Objective To explore the clinical indication and operative methods for different upper eyelid aging through perieyebrow incision.Methods We collected totally one hundred fifty-two cases in this study,including six males and 146 females,and aged from 26 to 80 years (average 47).There were 29 cases with only ptosis of upper eyelid,and the rest 123 cases were ptosis of upper eyelid with ptosis of eyebrow,sunken upper eyelid,bloated upper eyelid,or over-wide between eyebrow and eye region (compensatory eyebrow elevation).Through the incision of upper or lower margin of eyebrow,we treated these five types of upper eyelid aging by excision of redundant skin,orbicularis oculi muscle,frontal muscle,ROOF,or orbital fat,or ROOF elevation for upper eyelid rejuvenation.Results Patients were followed up for 3 to 120 months,with average 14.4 months.All ptosis of upper eyelid and over-wide between eyebrow and eye region patients were improved obviously.In 36 ptosis of upper eyelid with ptosis of eyebrow,seven of them treated with upper eyebrow margin incision got the best results;and the rest 29 patients treated with lower eyebrow margin incision,fifteen patients were lifted slightly,and the rest fourteen patients got no improvement.All scars of inferior eyebrow margin incision were invisible.Faded and applanate one millimeter wide scars were seen on two patients with superior eyebrow margin incision.In all patients with ptosis of upper eyelid,80％ patients with sunken upper eyelid were improved obviously,and 85 ％ with bloated upper eyelid were improved significantly.Conclusions Upper eyelid aging is divided into five categories.Upper eyelid aging could be corrected by perieyebrow approach.Our methods are simple,safe,fewer complications,and with short convalescence,which is the minimally invasive procedure recommended for Chinese patients with upper eyelid aging.

Objective To analyze the impact and quality of life of minimally invasive surgery combined with catheter attract surgery on patients with cerebral hemorrhage.Methods A total of 90 patients with cerebral hemorrhage in our department from February 2013 to De-cember 2014 were randomly divided into invasive group and the control group.Minimally invasive surgery group were given to cerebral hemor-rhage minimally invasive surgery combined with catheter attract surgery,the control group received traditional craniotomy.The postoperative recovery,nerve function scores,quality of life and morbidity between two groups were compared.Results The operation time and edema vol-ume of tissue postoperative 7 days in minimally invasive surgery group was significantly lower than those of the control group.The hematoma clearance rate 1 day after surgery was higher than that of control group,with statistically significant difference(P <0.05).NIHSS scores of two groups were gradually decreased 7 d,15 d,30 d after surgery(P <0.05).NIHSS scores of the minimally invasive surgery group 7 d,15 d, 30 d after surgery were lower than that of control group,with statistically significant difference(P <0.05).The scores of vitality,physiological function,physical function,general health,bodily pain,emotional function,social function,mental health after 6 months of the surgery in the min-imally invasive group was higher than those of control group,with statistically significant difference(P <0.05).The rate of postoperative pulmo-nary infection,electrolyte imbalance,gastrointestinal bleeding in MIS group were lower than those in the control group,with statistically signifi-cant difference(χ2 =5.400 0,4.405 7,4.615 4,P <0.05).Conclusion Minimally invasive surgery combined with catheter attract surgery can improve neurological function and quality of life for patients with intracerebral hemorrhage, and reduce the incidence of complications.

A thiosulfate-oxidizing bacterium TX was isolated from polysulfide wastewater treatment system.It was preliminarily identified as Halothiobacillus sp.according to its morphological,physiological proper-ties and similarity analysis of 16S rRNA gene sequence(GenBank accession No.EU871645).This bacte-rium was an obligate chemolithoautotrophic sulfur-oxidizing bacterium since it could utilize thiosulfate,elemental sulfur,tetrathionate,sulfide or sulfite as sole energy source but did not show growth on the me-dium with glucose,sucrose,fructose,lactose,mannose or yeast extract as sole carbon source.The optimal growth condition for thiosulfate oxidation was 30?C~35?C and pH 3.0~5.0 respectively.Significant reduc-tion in medium pH from 4.0 to 1.2 was observed due to oxidation of thiosulfate to sulfate during the batch culture incubation period.During the course of thiosulfate oxidation accumulation of tetrathionate was ob-served either in synthetic medium or in the mixed liquor from aeration tank of the polysulfide wastewater treatment system.This indicates that the "S4 intermediate(S4I)" pathway was responsible for thiosulfate oxidation in this bacterium.

Objective To compare the short-term efficacy of high-intensity ultraviolet B (UVB) versus 308-nm excimer laser for the treatment of vitiligo.Methods Eighty patients with vitiligo were equally divided into two groups to be treated with high-intensity UVB twice a week or 308-nm excimer laser once a week for eight weeks.Repigmentation was evaluated at the end of the treatment.Results After eight weeks of treatment,repigmentation of different degrees was observed in 83.6％ and 86.1％,and marked repigmentation in 42.1％ and 50％,of the UVB-and excimer laser-treated lesions,respectively.The response rate was significantly lower in facial lesions receiving high-intensity UVB radiation than in those receiving excimer laser radiation (49.1％ vs.68.4％,x2 =4.32,P ＜ 0.05),but similar at the other body sites between the two treatment (all P ＞ 0.05).The cumulative dosage required for initial repigmentation was similar between high-intensity UVB and 308-nm excimer laser (t =0.89,P ＞ 0.05),while the treatment sessions and cumulative dosage required for marked or better repigmentation were significantly increased in UVB-compared with excimer laser-treated lesions (both P ＜ 0.01).In addition,both high-intensity UVB and 308-nm excimer laser were suitable for childhood and active vitiligo.Conclusions Both high-intensity UVB and 308-nm excimer laser are safe and effective in the treatment of vitiligo with rapid onset of action,and the latter appears to be superior to the former in efficacy.

Objective To explore the operation timing and technique selection of floating knee injury in children.Methods According to Letts types,36 cases were divided into 5 types.The function outcome in every group was compared by Karlstrorm criterion according operation timing or technique selection respectively.Results Thirty-six cases were followed up for an average of 25 months(19 to 84 months).The rate of excellent and good results accounted for 94.12%(16/17) in one stage operation,78.95%(15/19)in stages,60%(6/10)in 2 stages,respectively.Conclusions It may be recommended to treat children with floating knee injury with open reduction intenal fixation or external fixation.The best operation time shall be urgent treatment of both femur and tibia fracture.

Objective To explore the changes of plasma brain natriuretic peptide(BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP)of sepsis combined with myocardial injury in newborns.Methods According to neonatal sepsis treatment program,45 cases of sepsis newborns in NICU of the Second Hospital in Lanzhou University from Jul.2007 to Jun.2008 were collected.According to the myocardial injury diagnostic criteria,45 cases neonatal sepsis were divided into myocardial injury group(n=22) and non-myocardial injury group(n=23).Myocardial injury group was also divided into congenital heart disease group and non-congenital heart disease group accor-ding to echocardiography.At the same time,30 healthy newborns were collected as healthy control group.Every newborns were tested the level of plasma BNP,NT-proBNP,creatine kinase-MB(CK-MB) and cardiac-troponin I (cTnI).Results There were significant difference between myocardial injury group,non-myocardial injury group and healthy control group in the levels of plasma BNP,NT-proBNP,CK-MB and cTnI,those in congenital heart disease group were higher than those in non-myocardial injury group and the healthy control group(Pa0.05).Conclusions BNP and NT-proBNP can be early used to diagnose myocardial injury and heart failure of neonatal sepsis associated with CK-MB and cTnI.In NICU,infants with sepsis should normally test BNP and NT-proBNP in order to early diagnose myocardial injury of neonatal sepsis.

Objective To investigate the roles of theaflavins(TFs) in airway mucus hypersecretion induced by human neutrophil elastase(HNE). Methods Human lung adenocarcinoma cell A549 was stimulated by HNE for mucus hypersecretion,and TF monomers(TF1,TF2 and TF3) were used for intervention.The effects of TF monomers on viability of A549 cells were examined by MTT method.After the effective doses of TFs were determined,A549 cells were divided into 4 groups for experiment.In control group,A549 cells were cultured with serum-free medium.In HNE treatment group,A549 cells were treated with HNE(50 nmol/L) for 24 h.In TF monomer intervention groups,A549 cells were pre-treated with TF1,TF2 or TF3(50,100 or 200 ?g/mL) for 24 h,and were then treated with HNE for another 24 h.In AG1478 intervention group,A549 cells were pre-treated with AG1478(5 ?mol/L),an epidermal growth factor receptor blocker for 30 min,and were then treated with HNE for another 24 h.The changes in mucin(MUC) after treatment by different doses of TF1,TF2 and TF3,and by TF3(200 ?g/mL) for different time(12 h,24 h and 36 h) were detected.The changes in MUC5AC mRNA expression and MUC5AC protein expression were detected by RT-PCR and ELISA,respectively. Results The MUC5AC mRNA expression and protein expression in HNE treatment group were significantly higher than those in control group(P
