Objective To evaluate the value of carcino embryonic antigen(CEA),carbohydrate antigen 19,cytokeratin(CYFRA21-1),squamous cell cancer antigen(SCC) and neuron specific enolase(NSE) for the evaluation of chemotherapy response in the patients with advanced lung cancer.Methods One hundred and thirty-six patients with advanced lung cancer(lung cancer group) and 40 patients with lung benign disease(control group) were collected.The lung cancer group was treated with at least two courses of chemotherapy.The CYFRA21-1,SCC,CEA and NSE levels before chemotherapy were compared among the lung cancer group,control group and the patients with different pathological types.The above mentioned tumor markers levels before and after chemotherapy were compared among the patients with different curative effects in the lung cancer group.Results The levels of serum NSE,CYFRA21-1,CEA and SCC before treatment in the lung cancer group were higher than those in the control group(P<0.01);the serum CEA level of the squamous carcinoma group was higher than that of the adenocarcinoma group and the small cell carcinoma group(P<0.01),and the serum NSE level of the small cell carcinoma group was higher than that of the adenocarcinoma and squamous cell carcinoma group(P<0.01),and the levels of CYFRA21-1 and SCC of the squamouscarcinoma group were higher than those of the adenocarcinoma and small cell groups(P<0.01).The serum CEA level of patial remission(PR) patients in adenocarcinoma group was significantly decreased(P<0.01),the serum SCC level of PR patients in the squamous cell carcinoma group was significantly decreased(P<0.05),and the serum NSE level of PR patients in small cell carcinoma group was significantly decreased after chemotherapy(P<0.01).The difference of serum NSE,CYFRA21-1 and SCC after chemotherapy in stnble and prosgoressive patients of various groups were not statistically significant(P>0.05).Conclusion CEA,CYFRA21-1,SCC and NSE can be used as the effective evaluation indexes of chemotherapy in lung adenocarcinoma,lung squamous cell carcinoma and small cell carcinoma,but which has little significance in the patients without effect of chemotherapy.

OBJECTIVETo survey the current situation of hypertension among "three minority ethnic groups" in Inner Mongolia Autonomous Region.

METHODSHypertension epidemiological survey among Three Minority Ethnic Groups and Han nationality aged ≥ 18 years was performed from June to December 2010.

RESULTSThe prevalence rate of hypertension among the surveyed population was 29. 4% (630/2 146) ( standardized prevalence was 34.6%). The prevalence rate of hypertension in male was 33. 8% (359/1 062) ( standardized prevalence was 39.9%), and the prevalence rate in female was 25.0% (271/1 084) (standardized prevalence was 26.6%) and the prevalence rate in male was higher than in female (P < 0.01). The prevalence rate of hypertension for the Oroqen nationality, Ewenki nationality and Daur nationality was 33.8% (92/272), 32.4% (170/524), and 30.2% (174/576) respectively (standardized prevalence was 33.7%, 33.1%, and 31.3%), and which was significantly higher than in the Han nationality (25.1% (194/774), P < 0.01) (standardized prevalence was 25.8%). The awareness, treatment and control rate of hypertension in the Oroqen nationality residents was 64.1% (59/92), 56.5% (52/92), 27.2% (25/92) (standardized rate was 63.5%, 56.8% and 27.4%), and 60.0% (102/170), 53.5% (91/170), 24.1% (41/170) ( standardized rate was 62.9%, 56.7%, 26.6%) in the Ewenki nationality residents, and 59.2% (103/174), 54.0% (94/174), 20.7% (36/174) (standardized rate was 50.3%, 54.7%, 21.4%) in the Daur nationality residents, and 65.0% (126/194), 57.7% (112/194), 27.3% (53/194) (standardized rate was 63.3%, 56.5%, 27.1%) in the Han nationality residents. Awareness rate, treatment rate and control rate were similar among different nationalities (all P > 0.05).

CONCLUSIONThe prevalence rate of hypertension among " three minority ethnic groups" residents in Inner Mongolia Autonomous Region is high and comprehensive prevention and therapy strategies are warranted to reduce the hypertension burden in these residents.

Objective To investigate the effectiveness of radio gu ided surgery (RGS) in lung carcinoma by using ~18F-FDG. Methods Forty mice bearing lung adenocarcinoma were divided randomly into two gro ups according to presence or absence of the lung metastasis. A dose of 200?l (1 00?Ci) of ~18F-FDG was injected via the tail vein. The external radioimmu nography was performed after injection. All viscerae and tumor were detected i n vivo by means of a hand-held gammaray-detecting probe (GDP), and the radio active distribution was analyzed with the well-gammaray detector. Resul ts The tumor images in mice were clear, and the images were best at two hours after injection. The values of %ID/g of tumor and heart obtained by well -gammaray detector were higher than those of other organs. Ratios of tumor/norm al tissue (T/NT) except cardiac muscle being detected by GDP ranged from 3.71 t o 13.57. There was a significant difference between the radioactivity of lung t issues in lung metastasis group and that of control group (P

To prepare salvianolic acid phospholipid compound. With the compound of salvianolic acids and soybean phospholipid as the index, mono-factor experiment and orthogonal design experiment were conducted to screen its technical parameters. According to the results, the optimal preparation conditions of salvianolic acid phospholipid compound were that THF were taken as the reaction solvent, the concentration time was 3 h, the reactant concentration was 5 g x L(-1), the mass ratio of salvianolic acids and phospholipid was 1: 1.5, and the reaction temperature was 40 degrees C. The oil/water partition coefficient of the prepared salvianolic acid phospholipid compound significant increased in water and buffers with different pH values. The results of phase analysis such as DSC, XRD and FTIR indicated that salvianolic acids existed in phospholipid in an amorphous state.

Implant-related infection is a commonly occurred complication in orthopaedics. The surface modification methods frequently used for anti-infection of implant surface were minimizing bacteria adhesion,grafting antibacterial agents and improving osteointegration. The pathogenesis and characteristics of orthopaedic implant-related infection and the research advances in the surface modification of orthopaedic implants for anti-infection are described in this paper,providing a reference for the research of novel implants with anti-infection characteristics.

Objective To evaluate the effects of diagnosis and treatment of acute pancreatitis com- plicating pseudoaneurysm by CT scan and transcatheter embolization.Methods Eighteen cases of acute panereatitis complicating pseudoaneurysm were performed abdominal angiography and transcatheter em- bolization.The CT and digital substraction angiography(DSA)findings and clinical data were retrospec- tively analyzed.The location of pseudoaneurysm and hemostasis were observed.Results CT scan re- vealed regional or diffuse slight high density fluid collections in abdominal cavity of all patients.En- hanced CT showed contained extravasation of contrast which indictated ruptured the pseudoaneurysm. DSA revealed 22 pseudoaneurysm,and 20 had evidence of bleeding.All pseudoaneurysms were success- fully embolized with coils,and hemostasis was achieyed in 18 pseudoaneurysm immediately.Conclusions The acute pancreatitis complicating pseudoaneurysm can be examined with CT scan and transcatheter embolization is safe and effective therapeutic method.
