Objective:This study aimed to investigate the clinical significance of hormone receptor status detection in simultane-ous axillary metastasis for hormone receptor-negative primary breast cancer patients. Methods:Using immunohistochemical methods, hormone receptor status detection in axillary lymph node metastasis was performed among breast cancer patients with simultaneous ax-illary metastasis in the First Affiliated Hospital of Chongqing Medical University. The subjects comprised patients who visited the clin-ic for follow up or those who were hospitalized from July 2012 to January 2013. Endocrine therapy was given for patients diagnosed with positive hormone receptor in their simultaneous axillary metastasis. Results:Out of 56 patients with hormone receptor-negative primary breast cancer, 14.3%gained estrogen receptor (ER), 3.6%gained progesterone receptor (PR), and 5.4%gained ER and PR in their simultaneous axillary metastasis, and then underwent endocrine therapy. The discordance rate of hormone receptor expression be-tween primary tumor and axillary metastasis was 23.3%. Conclusion:Some discordance rates of hormone receptor status between pri-mary tumor and simultaneous axillary metastasis were observed. Through hormone receptor status detection in simultaneous axillary metastasis, we may possibly distinguish patients with negative ER and PR, among whom endocrine therapy may be active.

Objective To study the effects of matrine (MAT) on the apoptosis and the expression of PEG10 in human hepatocarcinoma cell line HepG2. Methods MTT assay was used to determine the proliferation-inhibition activity by MAT to HepG2 cell. JC-1 staining was prepared to detect the change of mitochondrial membrane potential in HepG2 cells after MAT was given. RT-PCR and immunocytochemical method for detecting the PEG10 gene and protein expression levels were used. Results MAT could inhibit the HepG2 cell proliferation above the concentration of 0.125 mg/mL (different from above-->MAT ≥ 0.1 g/L) and in a concentration-dependent and time-dependent manner(P<0.01). JC-1 staining and flow cytometry detection showed that MAT can significantly decrease the mitochondrial membrane potential of HepG2 cells (P < 0.01). The RT-PCR and immunocytochemical staining results showed that 0.5 and 2.0 mg/ml (different from Chinese) MAT could reduce PEG10 gene and protein expression obviously. Conclusion MAT could decrease the expression level of PEG10 gene and inhibited cell proliferation,change the mitochondrial membrane potential and induce HepG2 cell apoptosis.

Objective To investigate the relationship between the anti-earthquake military rescuers' psychosomatic health and social support, and observe the effect of intervention to the army men who suffered troubles.Methods By cluster random sampling, 152 military rescuers and 139 army men not taking part in the rescues were investigated by Facility Psychosomatic Health Scale and Social Support Rating Scale. Mental intervention or medication was performed to those produced psychosomatic health. Results The scores of somatic symptoms,mental status,psychosomatic health and social support of military rescuers and the control group were (4.09±4.70) ,(2.18 ±3.16) ,(6.27 ±7.08) ,(6.14 ±4.20) and (2.11 ±4.16) ,(1.37 ±3.09),(3.47 ±6.55),(4.57 ± 4.17 )respectively, the difference was significant(P＜0.05). The somatic symptoms had significantly positive correlation with mental status in military rescuers (r=0.17～0.52, P＜ 0.05 or 0.01 ). Failure of social support had positive correlation with mental disorders (r=0.18～0.40, P＜0.05 or 0.01). The degree of social support was the main factor which had affected on the psychosomatic health of military rescuers. The somatic symptoms of military rescuers were apparently higher than their mental symptoms. Mental and pharmaceutical intervention showed good effect on them. Conclusion There is an apparent effect for military rescuers injured seriously psychosomatic health through medication or mental intervention.

Objective To evaluate the effects between video endoscopic inguinal lymphadenectomy (VEIL ) and open inguinal lymphadenectomy(OIL) to provide the evidence-based basis for the selection of the clinical therapy schemes .Methods The related clinical controlled trial literature on the effective comparison of VEIL and OIL were retrieved from the databases of PubMed ,Co-chrane library ,Elsevier ,CNKI and Wanfang database .The screening was independently performed by 2 reviewers according to the including and excluding criteria .The related data were extracted and performed the meta analysis by the RevMan 5 .2 software .Re-sults A total of 4 trials were included .There were 146 cases of inguinal lymphadenectomies ,in which 61 cases were VEIL and 85 cases were OIL .The meta-analysis results showed that there were no statistical differences between the two operation modes in terms of the operative time(WMD=32 .33 ,95% CI -25 .70-90 .36 ,P=0 .27) ,intraoperative blood loss(WMD=9 .10 ,95% CI -76 .03-94 .23 ,P=0 .83) ,number of removed lymph nodes(WMD=0 .77 ,95% CI -1 .66-3 .20 ,P=0 .53) ,number of positive re-moved lymph nodes(WMD=0 .08 ,95% CI -0 .23-0 .40 ,P=0 .61) ,postoperative drainage time(WMD= -1 .30 ,95% CI -6 .40 -3 .80 ,P=0 .62) ,postoperative hospital stay (WMD= -4 .02 ,95% CI -10 .19-2 .15 ,P=0 .20) ,but the difference between VEIL and OIL in term of surgical complications had statistical significance (OR=0 .08 ,95% CI 0 .03-0 .26 ,P<0 .01) .Conclusion VEIL has equivalent efficacy to OIL ,but has less surgical complications .
