Objective To investigate the values of combined determination of pleural effusion and serum carcinoembryonic antigen (CEA), cytokeratin 19 fragment (CYFRA21-1), neuron-specific enolase (NSE), and squamous cell carcinoma antigen (SCC-Ag) in diagnosis of lung cancer. Methods 101 patients with pleural effusion were reviewed retrospectively. Expressions of CEA, CYFRA21-1, NSE and SCC-Ag in pleural fluid and serum were detected; the optimum cut-off points resulting from the best sensitivity-specificity balance in the receiver operator characteristic (ROC) curves were constructed. The expressions of the tumor markers were compared among different pathological types of lung cancer. Results The levels of tumor markers in both pleural effusion and serum were significantly higher in patients with lung cancer than the benign group (P < 0.05). The expression levels and positive rate of CEA for lung adenocarcinoma, NSE for small cell lung cancer, and CYFRA21-1and SCC-Ag for pulmonary squamous cell carcinoma were higher than any other single detection (P < 0.05). Combined detection of the tumor markers in pleural fluid and serum improved the detection rate of lung cancer. Conclusions Combined detection of pleural effusion and serum tumor markers has important reference value in the detection of lung cancer and in pathological typing.

Objective: To study the cytocompatibility of nanophase alumina ceramics with osteoblasts. Methods: Alumina ceramics were prepared via wet chemistry techniques. The grain size of alumina of interest in the present study was determined by scanning electron microscopy and atomic force microscopy with image analysis software. Primary osteoblast culture was established from rat calvaria. Protein content, synthesis of alkaline phosphatase(ALP) and deposition of calcium-containing mineral by osteoblasts cultured on nanophase alumina ceramics and conventional alumina ceramics for 7, 14, 21 and 28 d were respectively examined. Results: The average surface grain size of the nanophase and conventional alumina compact formulations was 60 nm and 1.80 ?m respectively.Synthesis of ALP and deposition of calcium-containing mineral were significantly greater by osteoblasts cultured on nanophase than those on conventional ceramics after 21- and 28- day culture. Conclusions: Nanophase alumina may stimulate ALP synthesis and calcium deposition of osteoblasts.

0.05) between two groups in the above results.Disc agar diffusion test showed the sensitivity rates of overall clinical isolates to gatifloxacin and levofloxacin were 97.56% and 92.68%,respectively.The incidence of adverse drug reactions(ADR) of two groups were 23.91% and 43.75%,respectively.In 5 cases severe ADR were found. CONCLUSIONS Sequential therapy of gatifloxacin may get satisfactory results in lower respiratory tract infections of elder people.The irrational use of drugs is an important factor to increase ADR(including collateral damage).So we should pay attention to the ADR and grasp the indications strictly and use the drugs appropriately,especially for the elder patients.

Objective To investigate the efficacy of uterine artery chemoembolization in the treatment of locally advanced cervical cancer.Methods A total of 268 patients with locally advanced cervical cancer were treated with uterine artery chemoembolization in our department.The stage distribution among the patients included 132 stage Ⅰ B2,85 stage Ⅱ A1 and 51 stage Ⅱ A2.There were 223 patients of squamous cell carcinoma,24 patients of adenocarcinoma,9 patients of adenosquamous carcinoma,small cell carcinoma of the 7 patients,5 patients of neuroendocrine carcinoma.Transcatheter uterine artery infusion of paclitaxel and nedaplatin,gelatin sponge particles was applied for uterine artery embolization.The clinicopathological parameters were analyzed,and their impacts on tumor response were investigated.RECIST criteria were used to evaluate the response in solid tumors.Student t test was used to compare cervical tumor diameter before and after treatment,and Chi-square test was used for comparison of categorical data.Follow up examinations included pelvic ultrasound,gynecology,vaginal stump cell smears.Results Of the 268 patients,74 (27.6％) patients showed a complete response,160 (59.7％) patients had a partial response to uterine artery chemoembolization,and the overall response rate was 87.3％.A total of 258 (96.3 ％) patients underwent surgery,and pathological complete response were identified in 46 (17.2％).Forty (14.9％) patients were found to have lymph node metastasis after surgery.Response rates of stage Ⅰ B2 and Ⅱ A cases were 94.7％ and 80.1％,respectively,P ＜ 0.05.Patients with squamous cell carcinoma showed a better response rate than patents with other pathological types (94.2％ vs.53.3％),P ＜ 0.05.Initial tumor volume and cycles of preoperative uterine artery chemoembolization had no effect onthe response rate.Conclusions Uterine artery chemoembolization can increase the rate of surgical resectionof patients with locally advanced cervical cancer and can improve the reaction rate with tolerable side effect.It is an applicable option of treatment for patients with locally advanced cervical cancer in the neoadjuvanttreatment.

Objective To observe the expression of CD166 in advanced non-small cell lung cancer (NSCLC),and to explore the relationship between expression of CD166 and clinical characteristics,platinum-based chemotherapy effect of NSCLC patients.Methods A total of 64 cases of NSCLC patients at stage of Ⅲ,Ⅳ were enrolled.Tumor tissue samples were obtained before chemotherapy by bronchoscopy or lung biopsy,and immunohistochemical was used to detect the expression of CD166.All patients received platinum-based chemotherapy(NP/TC/ GP) for 2-4 cycles as the first line treatment.RECIST criterion was used for therapeutic evaluation.Results 46.9% (3 0 cases) of the patients with CD 1 6 6 was positive.The CD 1 6 6 expression was related with smoking (smoking 62.1%,no-smoking 34.3%,x2 =4.916,P =0.027) and degree of differentiation (moderately,low grade 68.2%,high grade 35.7%,x2 =6.112,P =0.013).The effectiveness rate of chemotherapy in CD166 positive patients was 23.3% (7 cases),was significantly lower than 61.8% in CD166 negative patients(21 cases,x2 =9.565,P =0.002).Conclusion NSCLC had CD166 expression,and the expression positive rate was increased in patients with smoking,and low differentiation cancer.The effectiveness rate of platinum-based was decreased in patients with CD166 positive expression,and detection of CD166 can predict the late NSCLC platinum-based chemotherapy effect.

Objective To investigate the clinical application and manifestation of dynamic contrastenhanced MRI (DCE-MRI) in differentiating true progession from pseudoprogression in patients with gliobastomas.Methods Twenty five glioma patients were treated with postoperative concurrent chemoradiotherapy and enrolled in this study.All patients were underwent DCE-MRI using a 1.5T scanner.Fifteen patients were confimmed by secondary pathology or clinical and imaging follow-up of patients with gliomas true progession (TP),10 patients were pseudoprogress (PP).Nonparametric Mann-Whitney test was used to compare perfusion parameters between two groups (TP and PP),were used for receiver operating characteristic (ROC) curve analysis to clear if these parameters can be the indicators to differentiate true progession from pseudoprogression.Results Ktrans (volume transfer constant),Ve (fractional volume of extravascular extracellular) values between TP and PP glioma groups were statistically significant,K and Ve values were significantly higher in the TP group than in the PP group (P ＜ 0.05).The areas under the ROC curve are 0.990 and 0.847,respectively.Kep (efflux rate constant) value,Vp (fractional volume of plasma) value in the identification of glioma TP group and PP group was not statistically significant (P ＞ 0.05).Conclusions DCE-MRI can be used to identify glioma TP and PP,Ktrans value and Ve value have clinical significance.

Objective To investigate the risk factors and preventive strategies of patients with diffuse axonal injury(DAI) with deep veins thrombosis in lower limbs (LDVT).Methods One hundred and thirty cases of diffuse axonal injury patients with lower limb vascular were divided into LDVT group(22 cases) and non LDVT group(108 cases) based on ultrasound.The information including long-term bed,plasma fibrinogen level,varicose veins,hypertention,sex,age,smoking,alcohol drinking,diabetes,obesity,Glasgow Coma Scale (GCS) were collected.Results There were significant different between LDVT and non-LDVT group in terms of longterm bed time,hypertension,smoking,diabetes,high plasma fibrinogen,age,low GCS score correlated with LDVT (x2 =7.08,5.99,5.17,4.70,3.55,12.72,t =27.80,P ＜ 0.05).Gender,drinking,obesity,varicose vein factors had no correlation with LDVT(P ＞ 0.05).Conclusion Diffuse axonal injury in patients with LDVT is more common in patients with older age,hypertension,low GCS score,the higher the plasma fibrinogen.

Objective To investigate the clinical therapeutic effect of comprehensive treatment in young women with cervical car-cinoma.Methods A total of 52 young women with cervical carcinoma were treated with uterine artery chemoembolization.50 cases underwent radical hysterectomy and pelvic lymphadenectomy after interventional therapy.The patients with pathological risk factors were given supplementary radiotherapy.Results The clinical overall response rate was 88.5%.96.2% of patients underwent sur-gery and lymph node metastasis rate was 26.9%.The 2,5 year overall survival rates of patients were 91.5%,71.2% respectively. Conclusion The comprehensive treatment can improve overall survival rate and quality of life for young woman with cervical carci-noma.Postoperative patients with pathologically related risk factors should be treated with supplement chemoradiotherapy.

Objective To compare the efficacy and side-effects of preoperative neoadjuvant uterine arterial chemoembolization and venous chemotherapy in treating cervical cancer in young female patients. Methods A total of 241 young females(≤35 years old) with cervical cancer were enrolled in this study. The clinical data were retrospectively analyzed. The patients were divided into group A (n=63) and group B (n=57). Patients in group A received preoperative neoadjuvant uterine arterial chemoembolization with subsequent surgery, while patients in group B were treated with preoperative neoadjuvant intravenous chemotherapy followed by surgery. The chemotherapy scheme included carboplatin (50 mg/m2) and gemcitabine (1 000 mg/m2). The short-term effect, the amount of blood loss during the surgery, pathological findings and the side-effects of the two groups were compared. The Kaplan-Meier method was used to calculate survival rate, and the log-rank test was used for survival difference analysis. Results The short-term response rate of group A was 90.5%, which was significantly higher than that of group B (71.9%), the difference between the two groups was statistically significant (χ2=7.5, P<0.05). The resection rate of group A was 95.2%, which was higher than that of group B (84.2%). The amount of intra-operative blood loss of group A and group B was (443±263) ml and (695±312) ml respectively, the difference was statistically significant (t=4.802, P<0.05). The pathological complete remission of group A and group B was 9.5%(6/63) and 5.3%(3/57)respectively; the differences in postoperative pathological results between the two groups were statistically significant (χ2=12.3, P<0.05). The side effect of group A was milder than that of group B (P<0.05). The 5-year progression-free survival (PFS) rate of group A and group B was 73.0% and 54.4% respectively (χ2=4.471, P<0.05);and the overall survival (OS) rate of group A and group B was 77.8%and 63.2%respectively (χ2=3.022, P>0.05). In both groups, the clinical stage, the pathological grade and the size (≥ 4 cm) of the tumor were the main factors that could influence the prognosis in young females with cervical cancer (P<0.05). Conclusion The short-term efficacy of preoperative uterine artery chemoembolization is better than that of preoperative intravenous chemotherapy for the treatment of cervical cancer in young female patients. Besides, this therapy carries mild side effect, and it can improve the 5-year progression-free survival rate, although the long-term survival rate has not been obviously improved.

Objective To develop a quantitative immunohistochemistry assay for duck hepatitis B virus core antigen (DHB-cAg)in duck liver tissue.Methods By comparison with no repair antigen and repair antigen with high pressure,microwave and trypsin,the best solution of antigen retrieval was determined.By optimizing the parameter of image acquisition and de-ducting blank area,mean density of yellow areas was calculated using Image-Pro Plus 6.0 software.Using the assay devel-oped to determine the level of DHBcAg in liver tissue from duck infected by DHBV,anti-DHBV activity of DHBcMAb-TAT PTD conj ugate was examined.Results SABC method with no repair antigen was selected,which was better than other methods.DHBcAg expression in duck liver tissue could be objectively and accurately quantified by setting Image-Pro Plus 6.0 software parameters and calculating mean density of yellow areas.By comparison with the differences between mean densityat baseline of treatment and end of treatment,it was showed that DHBcMAb-TATPTD conjugate treatment dose-de-pendently reduced the levels of DHBcAg in liver tissue,which show that the assay developed could effectively evaluate the anti-DHBV activity of agent.Conclusion The immunohistochemistry assay developed in this study can objectively and accu-rately evaluate the level of DHBcAg in duck liver tissue.
