Résumé
Objective To study the metastasis rule and influence factors of cervical central group (Ⅵ region) lymph node in patients with papillary thyroid microcarcinoma.Methods The clinical data of 195 patients with papillary thyroid microcarcinoma were analyzed retrospectively.All patients received bilateral thyroidectomy and bilateral cervical central group lymph node dissection.Results All patients died without surgery and hospitalization,the incidence of postoperative complications was 2.1％ (4/195).The total incidence of cervical central group lymph node metastasis was 35.4％ (69/195).Factors relating to cervical central group lymph node metastasis rate were:age (OR =0.924),gender (OR =0.213),the number of foci (OR =2.208) and the sum of the tumor diameters (OR =2.106).Conclusions Patients with papillary thyroid microcarcinoma may suffer from lymph node metastasis of the cervical central group,and lymph node metastasis rate increases significantly in young or male patients,and when the lesions are multifocal or the sum of the tumor diameter ＞ 0.5 cm.
Résumé
ObjectiveTo discuss the clinical value of ultrasonically activated scalpel(UAS) in breast cancer patients who underwent 2-3 cycles of neo-adjuvant chemotherapy by comparing UAS and electric knives (EI) in modified radical mastectomy. MethodsFrom Jun.2009 to Aug.2011, 52 breast cancer patients taking 2-3 cycles of neo-adjuvant chemotherapy underwent modified radical mastectomy in our hospital. Among them, UAS group included 23 patients, and EI group included 29 patients.The 2 groups were compared in terms of the operation time, intraoperative blood loss, postoperative drainage tube duration, postoperative hospital stay, the number of lymph nodes retrieved, and the volume of subcutaneous hydrops.ResultsBetween the 2 groups, the difference of intraoperative blood loss and postoperative drainage tube duration had statistical significance(P ＜0.01 ).The difference of operation time, hospital stay, and subcutaneous hydrops had statistical significance ( P ＜ 0.05 ).The difference of the number of lymph nodes retrieved had no statistical significance ( P ＞ 0.05 ).ConclusionThere are good curative effects for breast cancer patients undergoing modified radical mastectomy by UAS and axillary lymph node dissection after neo-adjuvant chemotherapy, which is consistent with the conception of fast track surgery.
Résumé
A method of using Fourer transform infrared spectroscopy (FTIR) to detect 36 Ganoderma lucidun products rapidly and undamaged is reported. As the result, each of the samples has its characteristic infrared spectrum. By the difference of the relative intensity of those absorption peaks, different kinds of Ganoderma lucidums products can be detected. It is very fast, simple, reliable and has no solution effects.
Résumé
Three species of borneol from different origins, namely Borneol Camphor (extracted fromDryobalanops aromatica Gaerth. f. ), Balsamiferous Blumea Borneol (extracted from Blumeabalsamifera DC. ) and synthetic borneol, were studied by macroscopic and microscopic iden .tification and GC method. Their differences were revealed. The amount of borne0l and isob-orneol in the samples were determined.
