Objective To investigate the expressions of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER-2) and relationships of these expressions with the clinicopathology in breast cancer patients aged 70 years old and over. Methods The expressions of ER, PR and HER-2 were detected by immunohistochemical staining from 124 elderly breast cancer patients, and the relationships of these expressions with pathological classification, tumor size, lymph node metastasis and TNM stage were analyzed. Results Among 124 patients, the positive expression rate of ER and PR was 75.0% (93/124) and 71.0% (88/124),respectively. They were not associated with pathological classification, tumor size, lymph node metastasis or TNM stage (all P＞0. 05). The positive expression rate of Her-2(+++) and Her-2 (++) was 11.3% (14/124) and 24.2% (30/124), respectively. And the expression of Her-2 was significantly associated with tumor size, lymph node metastasis and TNM stage (P＜0. 05) but not with pathological classification (P＞0. 05). Conclusions The positive expressions of ER and PR are not correlated with the clinicopathology in elderly breast cancer patients. Her-2 overexpression is positively associated with tumor size, lymph node metastasis and TNM stage.

BACKGROUND: Coronary angiography is called "the golden standard" for the diagnosis of coronary heart disease (CAD). Foreshortening of vessel segments in angiographic projection images usually caused by the inappropriate projection angles or positions may lead to misdiagnosis or missed diagnosis.OBJECTIVE: To investigate the optimal angiographic views of main coronary artery and its branches in different somatotype or heart type patients and to investigate the specific relationships between the optimal angiographic views and the different somatotypes and heart types with computer-assisted techniques.DESIGN: A controlled observation.SETTING: Department of Cardiology, the Second Affiliated Hospital of Nanchang University.PARTICIPANTS: Altogether 1 369 patients were admitted to the Second Affiliated Hospital of Nanchang University to undergo coronary angiography from January 2001 to December 2006 and recruited for this study. Written informed consents of coronary angiography were obtained from all the patients. The protocol was approved by the Medical Ethics Committee of Medical College of Nanchang University.METHODS: All 1 369 inpatients were assigned into 3 groups by body mass index (BMI): fat somatotype group (n =489, BMI: 26-31 kg/m2, transverse heart type), general somatotype group (n =502, BMI: 23-25 kg/m2, general heart type), and thin somatotype group (n =378, BMI: 17-22 kg/m2 vertical heart type). In each group, all arteries including left main coronary artery (LM), proximal segment of the anterior descending coronary artery (LAD), distal-mid segment of LAD, proximal segment of circumflex branch (LCX), distal-mid segment of LCX, proximal-mid and distal segments of right coronary artery (RCA) were properly and carefully analyzed using Compart software, and then we got its optimal angiographic viewing angle. Finally, we arranged these data and induced whether different somatotype group patients have different optimal angiographic viewing angles specifically for some coronary artery or not.MAIN OUTCOME MEASURES: Optimal angiographic viewing angles.RESULTS: All 1369 patients participated in the final analysis. Optimal angiographic viewing angle for LM: left anterior oblique (LAO)(40±5)°/ caudal (CAU)(25±5)° or right left anterior oblique (RAO) 25°/CAU35°. In the fat somatotype group, the angle should be added 10° to its optimal angle, and in the thin somatotype group, the angle should be decreased by 10°, and the differences between the general somatotype group and the fat somatotype group or the thin somatotype group were statistically significant (all P < 0.05). Optimal angiographic viewing angle for proximal segment of LAD: RAO (50±8)°/ cranial (CRA)(23±8)°. In the fat somatotype group, the optimal angle should be added 10°, but in the thin somatotype group, it should be decreased by 10°. The differences between the general somatotype group and the fat somatotype group or the thin somatotype group were statistically significant (all P < 0.05). Optimal angiographic viewing angle for distal-mid segment of LAD: RAO (40±5)°/CRA (45±5)° or LAO (11±5)°/CRA (45±5)°. Optimal angiographic viewing angle for proximal segment of LCX: LAO (45±5)°/CAU (35±5)° or anteroposterior (AP)/CAU36°. Optimal angiographic viewing angle for distal-mid segmental of LCX: LAO (45±5)°/CAU (35±5)° or RAO (6±4)°/CAU (30±5)°. Optimal angiographic viewing angle for proximal-mid segment of RCA: LAO (35±5)°/CAU (14±5)° or LAO (48±5)°/CRA (15±5)°. For the thin or fat somatotype group, the optimal LAO angle should be increased by 15°, the optimal RAO angle should be decreased by10° for fat somatotype group and should be increased by 10° for thin somatotype group, and the differences between the general somatotype group and the fat somatotype group or the thin somatotype group were statistically significantly (P < 0.05). Optimal angiographic viewing angle for distal segment of RCA: LAO (53±5)°/CAU (17±5)°.CONCLUSION: The message can be got clearly about the whole coronary artery and the accuracy percentage of stenosis by changing angiographic viewing angle regularly to its own optimal angle in different somatotype or heart type patients. It's very important for making the choice of diagnosis and therapy

OBJECTIVE:To analysis the volatile components in wild strains of Rabdosia rubescensin in Jiyuan area. METH-ODS:Headspace solid phase microextraction (HS-SPME) was conducted to extract the volatile components in 43 wild species of R. rubescens,GC-MS was conducted to identify the components,and peak area normalization method was conducted to calculate the relative content of the components. RESULTS:The variety and relative contents of the volatility components in 43 wild species had obvious differences and the ranges of species number and relative content was from 0 to 11 and from 0 to 84.03% respectively. Caryophyllene,caryophyllene oxide,dihydroactinidiolide,phytone and patchouli alcohol were main components which existed in a variety of different strains of volatile components of R. rubescens,and were mainly composed of terpenes,ketones,alcohols and es-ters. In addition,fatty acids such as palmitic acid,oleic acid and linoleic acid were contained in a few individual varieties. CON-CLUSIONS:The internal quality in 43 wild species of R. rubescens has certain differences.
