Objective To observe the security and efficacy of sevoflurane inhalation in combination with remifentanil controlled hypotension in patients undergoing functional endoscopic sinus surgery.Methods Forty pa tients undergoing elective functional endoscopic sinus surgery were randomly divided into propofol group (group P)and sevoflurane group(group S).In group P,patients received remifentanil 0.2μg · kg-1 · min-1 and propofol 4 ～6mg · kg-1 · min-1 intravenously,those in group S received remifentanil 0.2pg · kg-1 · min-1 and continuous inhalation of sevoflurane 2 ～ 3％,the end-tidal concentration was 1.1 ～ 1.7MAC.MAP was retained at 65 ～ 75 mmHg in the two groups.MAP and HR were recorded before controlled hypotension (T1),5min after controlled hypotension (T2),30min after controlled hypotension(T3),the termination of surgery(T4) and 5min after the termination of surgery(T5).Record the patient opening eyes time,wake extubation time,duration of surgery,blood loss.Also observed with or without respiratory depression,drowsiness,restlessness,nausea,vomiting and other adverse reactions.The same surgery fell surgical field quality rating according to Fromme operative field score table.Results Compared with T1,MAP(F =73.68) and HR(F =24.60) decreased significantly(P ＜ 0.05) at the other time points.There was no statistically significant difference in MAP(t =0.90) and HR(t =1.00) at the same time points between the two groups (P ＞ 0.05).Extubation time (t =0.44),duration of operation (t =1.23),operative field score (t =0:43) and blood loss (t =0.58) has no significant differences (P ＞ 0.05).Conclusion Inhalation hypotension by sevoflurane is feasible and safe in the functional endoscopic sinus surgery.It shows good quality of surgical field and less adverse reactions.

Background and purpose: Human epidermal growth factor receptor 2 (HER-2) is the member of tyrosine kinase receptor family. Its differential expression plays the key role in choosing targeted drug for breast cancer. This study focused on screening the breast cancer cell clones of different HER-2 expression levels, and studying the bi-ological characteristics of these cells. Methods: Breast cancer SK-BR-3 cells were clonally purified, and the expression level of soluble HER-2 (sHER-2) from the culture supernatant was detected by the ECLIA on ADVIA Centaur CP System. Cell clones with high expression (>50.0 ng/mL), medium expression (15.8-50.0 ng/mL) and low expression (<15.8 ng/mL) of sHER-2 were identified, respectively. This study observed the morphological changes of cell strains with differential expression levels of sHER-2 by cell culture. Besides, biological characteristics were compared by a series of experiments in vitro, such as clone formation, scratch assay, and transwell detection. Results: Compared with normal breast cells, sHER-2 was overexpressed significantly in SK-BR-3 breast cancer cells. Furthermore, the abilities of clone formation, mobility and invasion of sHER-2 high expression cell strain [(51.3±3.4)%, (50.0±0.6)% and (53.5±4.2)%] were signifi-cantly higher than those of sHER-2 medium expression [(42.0±3.7)%, (19.5±3.4)% and (33.2±3.9)%] or sHER-2 low expression [(26.7±2.9)%, (13.6±1.0)% and (28.9±5.4)%], and the differences were all statistically significant (P<0.05). Conclusion: Breast cancer cell strain with high expression level of sHER-2 can enhance cell proliferation, promote cell motility and other biological effects, which may lay the foundation for clinical screening of targeted drug therapies for breast cancer.

ObjectiveTo compare the performance of color Doppler utrasonography (CDUS) alone,magnetic resonance imagine (MRI) alone, and the combination of the two in the diagnosis of thyroid carcinona (TC). MethodsCDUS and MRI results of 54 focuses of carcinoma in 45 cases diagnosed as TC by postoperative pathological results were reviewed. The sensitivity of CDUS, MRI, and the combination of the two in the diagnosis of TC was compared. ResultsThe sensitivity of CDUS and MRI was 77.78％ (42/54)and 81.48％(44/54) respectively. The difference had no statistical significance (P ＞ 0.05 ). The specificity of CDUS and MRI was 88.17％ and 92.47％ respectively, the positive predictive value was 79.25％ and 86.27％ respectively,and the negative predictive value was 87.23％ and 89.58％ respectively. The sensitivity of the combination of CDUS and MRI was 94.44％ (51/54). The difference between the combination and CDUS or MRI alone had statistical significance( P ＜0.05). ConclusionsCDUS has higher detection rate than MRI in microcalcification of TC focus. However, MRI can show more clearly of the peripheral invasion and cervical lymph node metastasis.The combination of the two can improve the accuracy of TC diagnosis.
