Objective To observe clinicopathological features and prognosis of suptypes in breast cancers. Methods SP method was applied on 509 operated breast cancer patients to examine ER,PR and Her-2 status which determined subtypes.Subtype definitions were as follows:Her-2-,ER+ and/or PR+ as Luminal A,Her-2+,ER+ and/or PR+ as Luminal B,Her-2-,ER-PR-as Triple-negative,Her-2+,ER-,PR-as ERBB2+. χ~2 test was applied to determine their association with clinicopathological features.Kaplan-Meier method was used to analyze disease free survival (DFS).Univariate regression and COX multivariate regression were preformed to analyze association between metastasis or recurrence and cliniopathological features. Results 40.5%of all cases (206/509) were identified as Luminal A,18.5%(94/509) as Luminal B,21.4%(109/509)as Triple-negative,19.6%(100/509)as ERBB2+.The rate of medulary type in triple negative breast cancer was higher than that in other subtypes(P<0.05).Significant difference in the rate of recurrence or metastasis was found among four subtypes(P=0.029).Cox regression analysis suggested that lymph node status and TNM stage were independent factors affecting the prognosis(P=0.000).DFS of ERBB2+and Triple-negative was 81.0% and 78.9% respectively,which was lower than that of Luminal A and Luminal B(88.8%、90.4%)(P=0.025).Conclusion Luminal A occurred at the highest prevalence.Triple-negative and ERBB2+ have a hiigher incidence of relapse or metastasis and poorer prognosis than Lurninal A and Luminal B.

This article conducted a study on the foreign postgraduate students in Chongqing Medical University from the development scope,resources of students,major distribution,finical supporting from the year of 2006 to 2012.Based on the former analysis,it is found that students are of poor quality.There are very less Chinese learning channels.It is very urgent to optimize enrollment and improve the quality of students.There should be multi-channel expansion of Chinese learning and training refined Chinese expert.

Erectile dysfunction (ED), as a common male disease, seriously affects the patients' sexual life quality. Most ED patients benefit from phosphodiesterase type 5 (PDE5) inhibitors, but some refractory ED sufferers fail to respond to them. With the rapid development of molecular biology, the relevant molecular signaling pathways of penile erection and molecular pathogenesis of ED have been gradually clarified, and attempts have been made at a better management or a complete cure of ED with advanced molecular biological methods such as the gene therapy. This article presents an overview on the research progress in the molecular signaling pathways, molecular pathogenesis, and gene therapy of ED.

Object:To find out college students' perceptions about counseling.Methods:By using a questionnaire about college students' view of counseling,875 college students of Zhejiang University from grade 1 to grade 4 were tested.Results:Most students acknowledged that counseling deals with mental issues and disorders. They were willing to help clients,and prefer counselors who are like their friends and family members.They agreed that counseling is helpful and,prefer one-hour sessions,which are free of charge.

[Aim] Discuss Chen's treatment effect of infants viral myocarditis ayyhythmia. [Methods] He made suit medicine on two cases and analysed the disease'classification and main clinical manifestation and relevant therapy and his empirical formula, according to some factors ,such as the etiology and pathogens, course of disease and so on. [Results] (1)For viral myocarditis early disease caused by tachyarrhythmia, Mr. Chen advocated using the methods to treat which is clearing away heat and toxin and calming the pulse, the prescription used is Qingxinjiedu Decoction;however, those ones with il ness are offered a way of suppiementing qi and nourishing yin and warming the heart yang in order to remove pulse frequency, Chen used the modified YiQiShengMai Decoction for treatment.(2) The professor Chen paid attention to clearing hot and humid and supplementing qi and warming yang to cure slow arrhythmia due to acute viral myocarditis,the modified Huolian Decoction is used for this disease; For the people with a long il ness delayed healing, Chen worked a Decoction by himself which is Wenyangfumai Decoction,so that it could supplement qi and warm yang and invigorate the circulation of blood through pulse; For the slow arrhythmia appeared to sequela period, Chen thought that treatment should be insisted on promoting blood circulation to remove blood stasis and warming and activating the heart yang, the prescription used is Tongmai oyal liquid.[Conclusion]Professor Chen had gained a satisfied effect to treat infants viral myocarditis arrhythmia with the methods of clearing away heat and toxin, supplementing qi and nourishing yin and warming the heart yang and removing pulse frequency from the different stages and types.

Objective To evaluate the efficacy of remifentanil combined with propofol in children of different age undergoing short-term ophthalmologic operation.Methods Forty-eight children aged 4-12 yr undergoing elective short-term ophthalmologic operation were divided into 4 groups(n=12 each)according to age and anesthetics:group ⅠPK aged 4-7 yr and group ⅡPK aged 8-12 yr received ketamine and propofol combined anesthesia;group ⅠPR aged 4-7 yr and group ⅡPR aged 8-12 yr received remifentanil and propefol combined anesthesia.In group ⅠPK and ⅡPK the anesthesia was induced with intravenous bolus of ketamine 2 ms/kg and ketamine 1-2 ms/kg.In group ⅠPR and ⅡPR the anesthesia was induced with intravenous remifentanil 1 μg/kg and respiratory rate(RR),cerebral state index(CSI)and SpO2 were recorded before anesthesia induction(baseline),2 min after induction,at the initiation of the operation,15 min after the initiation of operation and at emergence from anesthesia.Adverse effects during and after the operation,induction time,analepsia time,conscious recovery time and total sedation time were recorded.The mean infusion rate of remifentanil was calculated.Results Compared with the baesline,SP,DP,HR,RR and CSI were significantly decreased in 4 groups(P＜0.05).RR,CSI and incidence rates of adverse effects were significantly lower,and the emergence time and the recovery time of consciousness were significantly shorter in group ⅠPR and ⅡPR than in group ⅠPK and ⅡPK(P＜0.05).The average infusion rate of remifentanil was lower in group ⅡPR than in group ⅠPR(P＜0.05).Conclusion Remifentanil combined with propofol can produce good anesthetic effect in children undergoing short-term ophthalmologic operation,with less adverse effects,stable hemodynamics and rapid emergence from anesthesia.The dosage of remifentanil is difierent in children at different ages.

With the increasing incidence and prevalence of male sexual dysfunction, andrologists are more and more in need of accurate and efficient tools to assess therapeutic efficacy and patients' satisfaction and to help patients achieve satisfactory treatment results.
