As a kind of breast cancer surgery choice,the nipple-sparing mastectomy (NSM)saves the patients′nipple-areola complex (NAC)which has significant meaning for patients′cosmetic results and posto-peration reconstruction.However,the clinical application of NSMis still in controversial.Some hot topics about oncological safety of NSM have appeared in recent years,such as the screening criterion of the enrolled patients,the situation of NAC involvement and the complications after NSM and handing methods.

Objective To investigate the effect of lycopene (Lyc) on H9c2 cell apoptosis induced by angiotensin Ⅱ (Ang Ⅱ).Methods Using Ang Ⅱ (10 μmol/L) to stimulate H9c2 cells,we observed the protective effect of Lyc on H9c2 cells apoptosis.The H9c2 cells viability induced by different consideration of Lyc or Ang Ⅱ or both was detected by CCK8 assay.The expression levels of Bax and Bcl-2 in H9c2 cells were determined by real-time quantitative reverse transcription polymerase chain reaction (RT-PCR).Western blot was conducted to detect the protein expressions of Bax,Caspase 3,Caspase 9 and Bcl-2 in H9c2 cells.The apoptotic ratio of H9c2 cells was observed by TUNEL assay.Results Compared with control group,Ang Ⅱ could decrease the viability of H9c2 cells to (92.87±4.37)％.The result of RT-PCR showed that Ang Ⅱ decreased the expression level of Bcl-2,and Bax level was increased under the stimulation of Ang Ⅱ (P＜0.05),while the expression level of Bcl-2 was increased and Bax level was decreased under the co-stimulation of Ang Ⅱ and Lyc in a concentration dependent manner,which indicated that Lyc ameliorated the apoptosis of H9c2 cells.The result of western blot showed that the protein expressions of Bax,Caspase 3 and Caspase 9 were increased,but Bcl-2 was decreased after the stimulation of Ang Ⅱ (P＜0.05).While these phenomenon reversed apparently under the co stimulation of Ang Ⅱ and Lyc.A large number of apoptotic cells were observed under the stimulation of Ang Ⅱ through TUNEL assay.But the number of apoptotic cells reduced significantly under the co-stimulation of Lyc and Ang Ⅱ (P ＜0.05).Conclusions Lyc ameliorates the H9c2 cell apoptosis induced by Ang Ⅱ,which indicates that Lyc may have an important role in the treatment of various cardiovascular diseases.

TheStandardized Manipulations of Acupuncture and Moxibustion has been published and gradually standardized the clinical practice. It provided a solid foundation for the standardization of acupuncture and moxibustion therapeutic effects. It also provided powerful convictable effects on the accuracy and scientificity of acupuncture and moxibustion clinical practice, which gained well-acceptance from patients. In the treatment of certain diseases, acupuncture and moxibustion have become irreplaceable so that acupuncture and moxibustion can be strongly promoted both at home and abroad. There were some common problems occurred during the establishment of the national standardization onStandardized Manipulations of Oral and Lip Acupuncture. This article reviewed, analyzed and discussed questions occurred during the standardization establishment. The results showed that according to the principle of standardized production, a rigorous, scientific and reasonable text standard can be established. Advices or opinions gained during the process can be used as references for future standardization establishment. It was concluded that the standardization of acupuncture had great guidance in the acupuncture clinical application. It is an arduous and long-term mission to achieve and strengthen the position of international standardization of acupuncture and moxibustion. The government should increase the effort on investment and promotion of acupuncture and moxibustion standardization. Conversation and cooperation should also be strengthened with international communities to promote the standardization implementation.

Objective:To validate the Chinese Version of Depletion Sensitivity Scale (DSS) and test its validity and reliability.Methods:A sample of 499 postgraduates coming from a university in Beijing was investigated with preliminary questionnaire,249 of them were assessed for exploratory factor analysis(EFA) and 250 of them were assessed for confirmatory factor analysis (CFA) and testing of validity and reliability.The criterion validity was tested with the Self-Regulatory Fatigue Scale (SRF-S),Dual-Mode of Self-Control Scale (DMSC-S) and Adolescent Self-rating Life Events Check-list (ASLEC).Totally 280 students were retested for test-retest reliability with 2 week interval.Results:DSS was composed of 8 items in two factors,which were cognitive factor and behavioral factor.The two factors explained 60.7％ of the variances.The confirmatory factor analysis identified a two factor model (x2/df=4.18,RMSEA =0.09,NFI =0.95,NNFI =0.94,CFI =0.96,IFI =0.96,GFI =0.96,SRMR =0.05).The scores of depletion sensitivity were positively correlated with the scores of cognitive fatigue,behavioral fatigue,emotional fatigue poor control,punished,loss,relationship pressure and adaption problem (r =0.13-0.55,Ps ＜0.001).The Cronbach α coefficients were 0.80 for the total questionnaire and 0.79 and 0.73 for the two factors.The test-retest reliability were 0.52 for the total questionnaire and 0.46 and 0.58 for the two factors.Conclusion:It suggests that the Chinese version of Depletion Sensitivity Scale (DSS) is reliable and valid enough to be applicable to measure the depletion sensitivity of Chinese graduate students.

Objective To observe the effect of ligustrazine injection combined with chemotherapy on common immunological parameters in patients with advanced hepatocellular carcinoma.Methods Eighty cases diagnosed with advanced hepatocellular carcinoma from January 2013 to January 2015 in the hospital were randomly divided into observation group and control group, 40 patients in each group.The control group received only conventional treatment of chemotherapy and observation group received ligustrazine injection on the basis of control group.The levels of interleukin-1 (IL-1), IL-4 and transforming growth factor beta ( TGF-β) wwere compared based on the record between two groups pre-and post-treatment.Results There were no significant differences between two groups in IL-1,IL-4 and TGF-βlevels pre-treatment.After treatment, the IL-1, IL-4 and TGF-βlevels in observation group were lower than those in control group [(41.4 ±11.8)vs (76.0 ±12.2)ng/L,(118.5 ±39.9)vs(223.0 ±47.3)ng/L,(6.7 ±3.2)vs(11.7 ± 2.6)ng/mL, respectively, all P<0.05].Conclusion Ligustrazine injection combined with chemotherapy has an exact effect on improving the immunological parameters associated with advanced hepatocellular carcinoma without significantly increasing side effects, it is worthy of further research and application.

Objective To explore the improving way to repair the lower one-third of leg soft tissue defect transferred the adjacent flap with non-main vessel pedicle. Methods Analyzing 42 cases.using 4 kinds flaps with nonmain vessel pedicle.If it is fine the skin around soft tissue defect of the lower one-third shank,choosing adjacent adversed sural neurotaneous vascular flap or sapheenous nerve vascular flap.If the skin damaged,chosing gastrocnemius flap.If the soft tissue defect was large,combined adversed sural neurotaneous vascular flap with gastrocnemius flap.Osteomyelitis and peroneus previs musculocutaneous flaps were choosed for small soft tissue defect. Results All case observed 6 to 12 months,37 cases were survived completely,5 cases distal part necrsis partly,among them,2 cases transferred flap repaired;1 case musculocutaneous flap transferred, 2 cases after granulation tissue grown,skin grafted. Conclusion The flap transferred adjacent non-main vessel pedicle is the best way to repaire soft tissue defect of one-third lower leg.Different flap can fit with kinds of soft tissue defect.

Objective To study the effect of parenting styles on the children' s self-control,and distinguish the influence between father and mother.Methods The present study selected 1 531 children (766 girls) between 3-10 years old.Data on parenting style were collected by parenting style questionnaire,while data on children' s self-control were measured by dual-system of self-control scale.Principal component analysis was conducted to examine common method bias.Results (1) No common method bias was found in this study.(2) Boys scored (31.66±5.95) on control system lower than girls (32.91±5.49),t=4.071,P＜ 0.01,but they had higher scores (43.19±8.32) on impulsive system than girls (41.96±8.32),t=2.226,P=0.027.(3)The associations of children's self-control scores with parents' spoiling,neglectful,authoritarian,inconsistent style were significant (r=-0.054～-0.174,P＜0.05),while it correlated positively with parents' democratic style (r=0.231,r=0.243,P＜0.05).The correlation between children's impulsive system scores and parents' spoiling,neglectful,authoritarian,inconsistent style were significantly positive (r=0.116-0.195,P＜0.05),while its associations with parents' democratic style were significant (r=-0.107,r=-0.108,P＜0.05).(4) As controlling children's age and sex,father democracy (β=0.120),inconsistency (β=-0.159),and mother democracy (β=0.188) were significantly correlated with children' s self-control (R 2adj =0.107,P＜0.05).Father despotism (β=0.070),inconsistency (β=0.136),mother's democracy (β=-0.063),despotism (β=0.099) and inconsistency (β=0.061) significantly predicted children's impulsive system (R 2adj =0.082,P＜0.05).Conclusion Each dimension of self-control and parenting style is high correlation.Father and mother's different rearing traits and the combination of different rearing traits contributed variously to children' s self-control system.

Objective To develop the ego depletion aftereffects scale (EDA-S) and test its validity and reliability.Methods Based on literature analysis and the open questionnaire survey this study compiled the preliminary questionnaire.A sample of 801 subjects coming from a university in Beijing was investigated with preliminary questionnaire and 406 students were retested for test-retest reliability with 2 week interval.Results The EDA-S was composed of 38 items in nine factors,which were emotional regulation difficulty,social withdrawal,low efficacy,working memory impairment,low processing fluency,work burnout,fatigue,somatic distress and low adherence.The eleven factors explained 72.09％ of the variances.Furthermore,the result of CFA indicated that the model fitted the data with well construct validity(x2 =1744.62,df=629,x2/df =2.77,RMSEA =0.06,NFI =0.98,NNFI =0.98,CFI =0.98,IFI =0.98,GFI =0.85,SRMR =0.05) and its factors scores were positively correlated with the SFR-S scores(r=0.31-0.59,P＜0.001).The Cronbach α coefficients were 0.95 for the total questionnaire and 0.73-0.91 for the eleven factors.The test-retest reliabilities were 0.60 for the total questionnaire and 0.26-0.57 for the nine factors.Conclusion It suggests that the EDA-S is reliable and valid enough to be applicable to measure the depletion degree of adolescents.

Objective To analyze the cause of acute brain swelling,brain encephalocele in brain traumatic injury craniotomy,and the reason,diagnosis and treatment methods of progressive epidural hematoma.Methods The clinical data of 381 patients with brain traumatic injury craniotomy were retrospetively analyzed.Of 318 patients,27cases had progressive epidural hematoma during operation.Results 9 cases died because of functional failure of brain stem,the other 18 cases were all clinically cured.Conclusion If acute brain swelling and encephalocele occured during operation,the cause should be found quickly,especially when there was skull fracture or epidural hematoma on the contralateral brain,the head CT and operation should be taken immediately,and the bulging brain tissue should not be removed blindly,and the skull should not be forced to close,otherwise the prognosis maybe poor.

Objective To learn how the process of self-regulatory fatigue (SRF) mediates the effect of leadership styles on job satisfaction of young workers.Methods 723 young workers recruited from a business enterprise were required to response to questionnaire survey, including leader behavior description, self-regulatory fatigue and job satisfaction questionnaire.Results All young workers' job satisfaction was 3.78±0.69,31 years old and above were higher than 30 years old and under(t=-3.246, P＜0.01) ,and there was no significant difference in gender and education.Job satisfaction was significantly positively correlated with leadership style (r initiating structure =0.210, r ideration =0.272), and was significantly negatively correlated with self-regulatory fatigue (r=-0.333).Two dimensions of leadership styles,initiating structure (β=0.227, t=2.659, P＜0.01) and consideration (β=0.270, t=5.035, P＜0.01), had the predicted effects of job satisfaction (R 2 =0.098).Consideration dimension of leadership style had more influence on job satisfaction at the high level of self-regulatory fatigue (β=0.266, t=4.929, P＜0.01);the effect of initiating structure dimention on job satisfaction was influenced by gender (t=-5.154, P＜0.01);self-regulatory fatigue was mediator between leadership styles and job satisfaction, and the consideration dimension of leadership style had more mediation effect on job satisfaction than that of initiating structure dimention of leadership style (mediationconsideration=0.317,mediationinitiating structure=0.268).Conclusion Two dimensions of leadership style can affect job satisfaction, and are mediated by self-regulatory fatigue.The intervention of self-regulatory fatigue can help to improve the job satisfaction of young workers.
