Sentinel lymph node biopsy has been the standard axillary intervention for breast cancer patients with clinical negative axillary lymph nodes.Complete axillary dissection could be omitted for patients with negative sentinel lymph nodes.While, the optimal axillary intervention for patients with 1-2 positive sentinel lymph nodes remained controversial.This review introduced the latest research results of the axillary management for early stage breast cancer patients with 1-2 positive sentinel lymph nodes.

Objective:To investigate cerebral angiography Features of patients with ischemic cerebrovascular disease.Methods:One hundred and twenty seven patients with ischemic cerebrovascular disease were selected in our hospital from March 2013 to April 2015, statistical analysis of their cerebral angiography differences at different ages, different types of ischemic cerebrovascular disease.Results: One hundred and twenty seven patients were found 97 patients(76.4%) had cerebral artery occlusion or stenosis, simple intracranial stenosis 40 cases, 31 cases of simple extracranial stenosis, 26 intracranial and extracranial stenosis cases; on the view of age, young patients with simple intracranial stenosis (69.2%), while the proportion of elderly patients in intracranial and extracranial stenosis was 40.5%, significantly higher than the proportion of old and middle-aged patients; patients with ischemic cerebrovascular disease at different types of stenosis and stenosis had no significant difference.Conclusion: Patients with ischemic cerebrovascular disease in different age have different distribution and different stenosis, especially in the largest proportion of young patients with occlusion, while parts of the brain in patients with vascular stenosis and stenosis and ischemic cerebrovascular disease the type was no significant association.

BACKGROUND: Cardiac reserve indicators obtained under quiescent condition are used as evaluating index for cardiac reserve functions. However, most important aspect of cardiac dysfunction in heart failure is not the depressed cardiac performance noted at basal resting states, but rather the loss of cardiac reserve. OBJECTIVE: To develop a data processing and information management system for detecting cardiac reserve indicator with the widely used B mode ultrasound instrument in the ultrasonography field, and to provide guidance for B mode ultrasound instrument perfection. METHODS: General B mode ultrasound instrument as peripherals was connected with the pc by image acquisition card; ultrasound heart image diagnosis and management system including professional heart image acquisition and process and perfect data bank was develop. RESULTS AND CONCLUSION: An efficient and flexible mini picture archiving and communication system system was achieved, which realized image enhancement, geometric parameter measuring, convenient diagnosis report output, archive management and print function. Results demonstrated that with the powerful data process ability of PC, the system could improve the performance of the traditional ultrasound instrument in detecting cardiac reserve, which provide a powerful support for the further study.

Objective:To evaluate the security, efficacy and side effects of E_2 transdermal patch (Fem-7) in the treatment of menopausal syndrome. Methods:A total of 60 cases with menopausal syndrome (blood serum FSH >30 U/L,E_2 <109.8 pmol/L) were randomly divided into treatment group ( Fem-7 group) and control group (estrodiol valerate (E_2V) group) for 12 weeks treatment. Fem-7 group changed patch every 7 days and took the 2 mg medroxyprogesterone (MPA) every day. While the E_2V group took the 2 mg MPA and 1.5 mg E_2 V every day. Serum E_2, FSH, lipoprotein and coagulation function were evaluated at baseline and at the 12th week of the treatment. In addition, menopausal symptoms and some other index of security and side effects were also observed. Results:Kupperman indix in both groups was decreased and the mean value of E_2 was increased obviously. Hepatic function, renal function, coagulation function and blood glucose were no obvious change. Lipoproteina was descended markedly in Fem-7 group. Other index of security in both groups was no obvious change. Conclusions:Fem-7 patch is secure and valid for relieving symptom of menopause, especially for the women who is not sutable for oral medication.

Objective:To compare the effects of different anesthesia methods on stress hormones and hemodynamic changes in the patients with gynecological laparoscopic surgery. Methods:Retrospective analysis was carried out. Totally 145 patients with gynecolog-ical laparoscopic surgery were divided into two groups according to the anesthesia method, the control group with 72 cases was given routine remifentanyl propofol intravenous anesthesia, and the observation group with 73 cases was given routine propofol isoflurane com-posite anesthesia. Such hemodynamic indices as SBP, DBP and HR, and plasma NE, E, cort and AT II levels at different time points in the two groups were studied and compared, and adverse drug reactions were also observed in the two groups. Results:The BP and HR at T2 and T3 time point in the two groups were significantly lower than those at T0 time point (P<0. 05), and those in the obser-vation group were lower than those in the control group at the same time point(P<0. 05). The levels of NE, E, cort and ATⅡat T2 and T3 time point in the two groups were significantly higher than those at T0 time point (P<0. 05), while the increase in the observa-tion group was lower than that in the control group (P<0. 05). The incidence of adverse drug reactions (ADR), such as respiratory depression, hypertension, bradycardia and so on, and the total incidence of ADR in the observation group were both lower than those in the control group (P<0. 05). Conclusion:Compared with remifentanyl propofol intravenous anesthesia, propofol isoflurane composite anesthesia can keep the hemodynamic stability more effectively and reduce the stress reaction with fewer ADR and promising safety, which is worthy of wider application in clinics.

Subjective: To observe apoptosis of the cells in oral sq uamous cell carcinoma(SCC) induced by cerulenin. Methods: SCC TCA-83 cells and fresh tissue of SCC of tongue from 5 patients were expos ed to cerulenin (10 mg/ml) for 24 hours, then the genosome DNA of the cells was extracted and electrophoresed; the fresh tissue of SCC was assessed by TUNEL labeling. Results: DNA gel electrophoresis showed typical apoptic DNA ladders from TCA-83 cells. The rate (%) of TUNEL-positive cells in cerulenin treated tissue of SCC was 29.0?2.6～40.6?16.2,that in the control 2 . 0?1.7～14.7?0.6 (P

OBJECTIVE:To establish a method for the content determination of total flavonoids in onion extracts.METH_ ODS:UV spectrophotometry was adopted in the determination with the detection wavelength set at270nm.RESULTS:Good linear relationship with the absorbability was achieved when the detection concentration of eldrin was within a range of0.002～0.01mg/ml(r=0.9978),the average recovery was99.15%(RSD=1.52%).CONCLUSION:This method was simple,rapid and accurate.

OBJECTIVE:To observe the clinical efficacy and transdermal absorption of Suhong bone-penetrating massage drug for rheumatic arthralgia. METHODS:Suhong bone-penetrating massage drug(Chinese medicine) was applied in 300 cases with rheumatic arthralgia characterized by various symptoms such as bone spur, injury, scapulohumeral periarthritis, acute injury or chronic strain of articular surrounding soft tissue; Suhongtougu powder was used as control to treat another 120 cases with the same disease. The curative efficacies in two groups were compared. The effects of the effective components such as Muskone,Borneo Camphor,Menthol in Suhong bone-penetrating massage drug on the transdermal absorption of this preparation was investigated by transdermal test on mice. RESULTS:The total effective rate in the treatment group was 93.24% as compared with 80.00% in the control group, showing significant difference between two groups(P
