Purpose: To explore the clinical value of 99mTc-MIBI imaging in differentiating malignancies from benign breast masses. Methods: 195 patients underwent the examination for 99m Tc-MIBI. Comparative diagnosis was done by postoperative pathology in all cases. Results: 69 of the 84 cases of breast cancer were preoperatively diagnosed by 99mTc-MIBI, the causes of false-negative results were small size of the mass and the higher degree of malignancy. 102 of the 111 patients with benign lesions were scintimammographically negative, the cause of false-positive results was large fibroadenomas with surplus blood supply. The sensitivity was 82. 1%, specificity was 92.0%, and the diagnostic accuracy was 89.2%. Conclusions: 99mTc-MIBI examination is an effective, simple and noninvasive diagnostic method for primary breast cancer.

Objective To evaluate the efficacy and safety of repeated endoscopic sclerotherapy injection(ESI) and endoscopic variceal ligation(EVL) in eradication of esophageal varices among patients who survive an episode of first variceal hemorrhage with a high risk of rehaemorrhagia and death. Methods The correlated literatures were identified from Medline,Embsae,the Library Cochrance,PubMed and CNKI.RevMan 4.2 Software provided by the Library Cochrance was used for data analysis. Results A total of 4 randomized controlled trials were included.It was demonstrated that there was no significant difference in the esophageal varices eradication rate between repeated ESI and EVL(OR=0.75,95%CI: 0.48-1.15;P=0.19).However,the rehaemorrhagia rate of EVL after emergency hemostasis was significantly lower than that of ESI(OR=2.19,95%CI:1.44-3.31;P=0.000 2).Meanwhile,there was no significant difference in mortality between ESI and EVL(OR=1.34,95%CI:0.82-2.17;P=0.24).Little publication bias was found with funnel plot analysis. Conclusion EVL outperforms ESL in prevention of rehaemorrhagia in treatment of esophageal varices,while does no better than ESL in eradication of esophageal varices and mortality.

Acupuncture clinical trials are designed to provide reliable evidence of clinical efficacy, and SCI papers is one of the high-quality clinical efficacy of acupuncture research. To analyze these papers published in high impact factor journals on acupuncture clinical trials, we can study clinical trials from design to implementation, the efficacy of prevention and cure, combined with international standard practices to evaluate the effectiveness and safety of acupuncture. That is the core of acupuncture clinical trials, as well as a prerequisite for outstanding academic output. A scientific and complete acupuncture clinical trial should be topically novel, designed innovative, logically clear, linguistically refining, and the most important point lies in a great discovery and solving the pragmatic problem. All of these are critical points of papers to be published in high impact factor journal, and directly affect international evaluation and promotion of acupuncture.

OBJECTIVETo observe the effects of electroacupuncture (EA) with branch-foundation acupoint combination on the indices regarding pituitary-target gland axis in aging rats with yang deficiency, so as to explore its regulating mechanism on aging rats with yang deficiency.

METHODSForty healthy Sprague-Dawley female rats were randomly divided into a normal control group, a model group, an EA group and an EA control group, 10 rats in each group. Except the normal control group, the rats in the rest 3 groups were all treated with subcutaneous injection of D-galactose for 40 d, followed by intramuscular injection of hydrocortisone for 7 d to establish aging model with yang deficiency. After the successful establishment of model, the EA group was treated with EA at "Guanyuan" (CV 4), "Housanli" (ST 36) and "Baihui "(GV 20) while the EA control group was treated with EA at "Zhongji" (CV 3) "Yinlingquan" (SP 9) and "Yintang" (GV 29); the rats in the normal control group and model group were immobilized and fixed during the same time period. The treatments were given 6 times per week totally for 4 weeks. With radiation immunity analysis method, the 8 biological indices of pituitary-target gland axis, including thyroid-stimulating hormone (TSH), triiodothyronine (T3), tetraiodothyronine-4 (T4), adrenocorticotropic hormone (ACTH), corticosterone (CORT), estradiol (E2), luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were detected to observe the changes of their content.

RESULTSCompared with the normal control group, the serum level of TSH, T3, T4 and E2 were reduced in the model group (P<0.05, P< 0.01) while those of ACTH, CORT, FSH and LH were increased (P<0.05, P<0.01). Compared with the model group, the serum level of TSH, T3, T4 and E2 were increased in the EA group (P<0.05, P<0.01) while those of ACTH, CORT, FSH and LH were significantly reduced (P<0.05, P<0.01). Compared with the EA control group, the content of TSH was increased in the EA group without statistical significance (P>0.05), that of T3, T4 and E2 was increased (all P<0.05) and that of ACTH, CORT, FSH and LH was significantly reduced (all P<0.05).

CONCLUSIONThe electroacupuncture with branch-foundation acupoint combination has benign regulating effects on the key hormones of pituitary-target gland axis, which could effectively improve the dysfunction of pituitary-target gland axis that is caused by aging with yang deficiency; the efficacy of electroacupuncture with branch-foundation acupoint combination is superior to that of adjacent control acupoint combination.
