ObjectiveTo study the effects of different priming dose of muscle relaxant at the onset and endotracheal intubation conditions.Methods120 ASA Ⅰ～Ⅱ grade patients were randomly divided into 6 groups (n=6),vecuronium group (V 1,V2,V3) and cis-atrscurium group (C1,C2,C3).All patients were induced with propofol plasma (TCI)3 μg/ml,fentanil3 μg/kg.The V1 and C1 group were not given priming dose,and the V2,V3,C2,C3 groups were given priming dose of 10 μg/kg,20 μg/kg vecuronium and 15 μg/kg,30 μg/kg cis-atracurium.Intubating conditions were evaluated,and the onset time was monitored with train-of-four (TOF) technique.ResultsIntubating conditions were excellent in all patients.The onset time of priming groups of the four different doses was significantly shorter than that of the nonpriming group [(80.5±7.2) vs (146±10.7);(79.8±6.5) vs (146±10.7);(138.5±7.2) vs (218±10.7) ; (127.1±6.5) vs (218±10.7),P ＜ 0.05 ].ConclusionsThe taking-effect time of priming dose of muscle relaxant was significantly shorter than that of the nonpriming dose group.Increasing the priming dose not decrease onset time more than the smaller dose.

Objective To discuss the clinical value of D-dimer(DD) testing in diagnosis of patients with deep vein thrombosis(DVT) of the lower extremity.Methods An analysis retrospectively was made on the changes of DD testing in 106 cases of DVT at different periods after onset and different clinical stages of DVT,and DD testing in 99 patients with primary deep venous insufficiency(PDVI) as control group.(Results) DD was higher in the acute stage of DVT,and gradually decreased with time in chronic DVT,and was negative in the patients with PDVI;the positive rate was up to 85.7% in the distal DVT.Conclusions The DD testing can be used as one of the methods for diagnosis,prediction and prognosis of acute DVT,especially for diagnosis of distal DVT.

Objective To compare HER-2 state in breast cancer tissue deteced by fluorescent in situ hybridization (FISH) and immunohistochemistry (IHC) and analyze their correlation. Methods HER-2/neu protein expression and gene amplification were detected by FISH and IHC in 56 newly-diagnosed cases of female breast cancer from July 2008 to July 2009. Results Of the 56 patients, HER-2 protein expression (-), (+), (++), (+++) was 9 cases (16.1%), 29 cases (51.8%), 11 cases (19.6%) and 7cases (12.5%) respectively; 26 cases (46.4%) had HER-2 gene amplification while 30 cases (53.6%) didnt have. Type of HER-2 gene amplification was mainly HER-2(++) and HER-2(+++), and according gene amplification rate was 72 7% and 100%. HER-2 (+) gene amplification rate was 37.9 %(11cases) and no gene amplification was found in HER-2(-) tissue. The HER-2 positive rate using two methods had significant difference(χ2=19.778,P<0.01). HER-2(-) and HER-2(+++) had good consistency with the FISH results(Kappa=0.969),but HER-2(+) and HER-2(+ +) were poorly consistent with the FISH results(Kappa=0.271). Conclusions IHC is the preliminary screening method for detection of HER-2 expression. HER-2(-) and HER-2(+++) have good consistency with the gene amplification, and can guide clinical treatment. Some patients with HER-2(+) and HER-2(++) have HER-2 gene amplification. FISH is needed for targeted therapy.

Objective:We aimed to investigate the clinical efficacy of neoadjuvant chemotherapy combined with cytoreductive surgery and intraperitoneal hyperthermic chemoperfusion (IHCP) after the operation of patients with advanced ovarian cancer. Meth-ods:Analysis of 60 patients with advanced ovarian cancer was performed at the Zhengzhou People's Hospital from April 2009 to July 2012. The patients were divided into two groups, namely, the research and control groups. The research group was treated with neoadju-vant chemotherapy combined with cytoreductive surgery and IHCP twice (cisplatin at 80 mg), and subsequently, with chemotherapy (TC/TP). The control group underwent primary cytoreductive surgery and chemotherapy (TC/TP). We compared the differences be-tween the two groups in terms of the following parameters:operation time, bleeding volume, volume of ascites, and postoperative che-motherapy. Results:The treatments in the research group were more efficient than those performed on the control group in terms of all the intraoperative indicators, and the difference between the two groups was statistically significant (P<0.05). Conclusion:Compared with conventional methods, the neoadjuvant chemotherapy combined with cytoreductive surgery and IHCP after operation was more ef-fective for patients with advanced ovarian cancer. Thus, neoadjuvant chemotherapy combined with cytoreductive surgery and IHCP af-ter operation can be applied in clinical settings.

Objective To investigate the effect of nitric oxide synthase(NOS) inhibitors and L-arginine(L-Arg) on the prognosis of traumatic shock in rats. Methods Traumatic shock models of Sprague-Daulay rats were made and randomly devided into control group (n=24),L-NAME treatment group (n=24),AG treatment group (n=24) and L-Arg treatment group (n=24). Serum nitric oxide(NO) levels and oxygen partial pressure in tissues include skeletal muscles,liver and small intestine were detected at 1h,3h,5h after resuscitation. Meanwhile, hemodynamic data of the rats and their survival rates of 12h and 24h were monitored and recorded. Results Serum NO concentration was statistically lower after resuscitation in L-NAME group than that in control group, while there were no statistical significance of tissues oxygen partial pressure and survival rate in 12、24h between the two groups. AG could decrease serum NO levels only at late stage of traumatic shock,but no effect on the synthesis and relase of NO at early stage of traumati shock.AG could improve tissues oxygen partial pressure of the liver and small intestine, and prolonged the mean survival time. L-Arg could increase serum NO levels, and improve oxygen partial pressure of intestine and significantly increase the survival rate at 12h and 24h in rats with traumatic shock. Conclusions Treatment with AG and L-Arg can improve the prognosis of traumatic shock rats much better than that with L-NAME.

Objective To determine the clinical value of cytological diagnosis of the impressed specimens in the radical gastrectomy for patients with gastric cancer. Methods During radical gastrectomies for 52 patients with gastric cancer, 232 impressed specimens were taken from the tumor tissues,paratumor tissues, proximal and distal incision margin,and partial lymph nodes respectively, to detect if there was tumor cells by cytological examination and compared with the pathology. Results In the tumor tissues,there were no pseudo positive specimen,and the pseudo negative specimen occurred in 1.In the incision margin,there was no pseudo negative specimen,while 12 pseudo positive specimens were found.In the paratumor tissues,there were 3 pseudo negative and 10 pseudo positive specimens.In all specimens,the sensibility was 92.8%; specificity was 85.8%; accuracy rate was 87.9%. Conclusions Cytological examination of the impressed specimens in radical gastrectomy is helpful in detecting residue tumor tissue in the incision margin, especially in hospitals without rapid pathologic examination.If cytological examination is combined with rapid pathological examination,the results will be better.

Epidermal growth factor receptor (EGFR) is found to express at high levels in a variety of solid tumors including gliomas. This study was to examine the effect of an EGFR-tyrosine kinase inhibitor (AG1478) alone or in combination with cisplatin (CDDP) on the growth of glioma cells (U87). U87 glioma cells were treated with AG1478 (10 μmol/L) or CDDP (25 μmol/L) as a single agent or in combination for 24 or 48 h. The expression of EGFR and the components in its downstream signaling pathway [extracellular signal-regulated kinase (ERK), protein kinase B (AKT)] in U87 glioma cells was detected by Western blotting. Cell growth, cell cycle distribution and cell apoptosis were determined by MTT method and flow cytometry, respectively. The results showed that CDDP could induce the activation of EGFR and the components in its downstream signaling pathways in a concentration-dependent manner. The combined treatment of AG1478 with CDDP could inhibit the proliferation of U87 glioma cells, arrest the cell cycle and promote cell apoptosis. In the EGFR signaling pathway, AG1478 decreased the phosphorylation of ERK, AKT and EGFR in U87 glioma cells. It was concluded that the combined treatment of AG1478 and CDDP may exert synergistic inhibitory effects on the growth of glioma cells by suppressing the activities of EGFR, AKT and ERK.

Objective To explore the pattern of cervical nodal metastasis and the clinical significance of total thyroidectomy plus functional neck lymphadenectomy in papillary thyroid carcinoma patients. Methods Clinical and pathological data of 172 patients with papillary thyroid cancer who underwent total thyroidectomy plus functional neck lymph node dissection at Jinan Military General Hospital were retrospectively reviewed, including patient demographics, extent of surgery, parathyroid hormone level,recurrence, tumor pathology, such as tumor size, multifocality, capsular invasion, vascular invasion,extrathyroidal extension, and lymph node status. Results Of the 172 functional neck dissection patients (47 ambilateral), the incidence of lymphonodus metastasis in regions Ⅵ, Ⅳ and Ⅲ was 96. 3% ,78. 5%and 62.1% respectively. Rate of nodal metastasis was higher in patients with extracapsular invasion than in patients with no invasion ( P ＜ 0. 05 ). Serum parathyroid hormone levels significantly decreased immediately postoperatively in total thyroidectomy plus functional neck dissection and remained low for several weeks thereafter ( P ＜ 0. 01 ). The 5-, 10- and 15-year survival rate was ( 98. 83 ± 0. 82) %, (98. 23 ± 1.02 ) % and (96. 42 ± 1.43 )%, respectively. Conclusions Therapeutic neck lymph node dissection for papillary thyroid cancer is recommended for cervical nodal metastasis patients. Total thyroidectomy plus functional neck dissection is important in the treatment of papillary thyroid cancer.
