Sperm associated antigen 9(SPAG9),a new member of the c-Jun NH2-terminal kinase (JNK)interacting protein(JIP)family. plays a role in sperm-egg fusion and mitogen-activated protein kinase (MAPK)signaling pathway.Researches have shown that SPAG9 is closely related to the biological behavior of human malignant tumors, and plays an important role in the development of tumor.

Objective To study the X-ray signs of lung injury in acute ammonia poisoning.Methods The X-ray features of lung in ammonia poisoning in 37 cases were analysed and all patients were followed up for one year.Results The X-ray signs of lung in early of ammonia poisoning in 35 cases included increase of lung markings,lobular pneumonia,pulmonary interstitial emphysema and pneumonedema.In advanced stage in 15 cases,chronic bronchitis,pulmonary interstitial fibrosis and pulmonary bullae.Conclusion It's irreversible of injury that caused by acute ammonia poisoning in lung.

Objective To study the expressions of epithelial symbol factors including E-cadherin,?-catenin,and ?-catenin related to epithelial-mesenchymal transition(EMT) in C57 mice Lewis lung cancer and its mRNA expression affected by Feiyanning Decoction(Decoction for lung cancer).Methods The Real-Time PCR method was adopted to observe the E-cadherin,?-catenin,?-catenin mRNA expression of C57 mice with transplanted tumor in the right armpit and distal metastases and the affection of Feiyanning Decoction on the expression.Results The lung transplanted rate in the Feiyanning group was clearly lower than that in the model group(P

Coronary artery disease remains a major cause of mortality. Presence of atherosclerotic plaques in the coronary artery is responsible for lu-men stenosis which is often used as an indicator for determining the severity of coronary artery disease. However, the degree of coronary lumen stenosis is not often related to compromising myocardial blood flow, as most of the cardiac events that are caused by atherosclerotic plaques are the result of vulnerable plaques which are prone to rupture. Thus, identification of vulnerable plaques in coronary arteries has become increas-ingly important to assist identify patients with high cardiovascular risks. Molecular imaging with use of positron emission tomography (PET) and single photon emission computed tomography (SPECT) has fulfilled this goal by providing functional information about plaque activity which enables accurate assessment of plaque stability. This review article provides an overview of diagnostic applications of molecular imaging tech-niques in the detection of plaques in coronary arteries with PET and SPECT. New radiopharmaceuticals used in the molecular imaging of coro-nary plaques and diagnostic applications of integrated PET/CT and PET/MRI in coronary plaques are also discussed.

It is found that gambogic acid can play anti-tumor effects through different mechanisms in a variety of tumor cells,including induce apoptosis,inhibit telomerase and topoisomerase activity,inhibit the expression of heat shock protein and channel protein,inhibit tumor angiogenesis and metastasis and reverse multidrug resistance.Gambogic acid is expected to become a new anti-tumor drug,still need to be further explored its value in the field of anti-tumor.

Objective: To study the treatment of complicated and giant carotid body tumor. Methods: A giant carotid body tumor was dissected 2 years ago. The external carotid artery was embolized by means of catheterization before surgical intervention, and techniques of internal shunting and autogenous blood transfusion was used during the operation. Results: The tumor was resected completely without cerebral vessel disorders and major cephalic nerve injuries. Conclusion: The application of radial intervention of external carotid artery, shunting of internal carotid artery and autogenous blood transfusion are helpful to the treatment of giant and re operative carotid body tumor.

Objective To analyze the clinical pathologic features and prognosis of triple negative breast cancer. Method A total of 570 cases of breast cancer between January 2005 and June 2007 were analyzed,113 cases were negative for estrogen receptor(ER), progesterone receptor(PR) and HER-2 as the triple negative group, 48 cases were negative for ER, PR and positive for HER-2 as the control group. The clinical pathologic features, recurrence and survival of the patients were compared. Results The median age was 46 years old, 15 cases (13.3%) had a breast cancer family history or oophoroma family history,86.7%(98/113) of pathological types were invasive ductal carcinoma,lymph node metastases were detected in 31.0%(35/113 ) in the triple negative group. No significant difference was found for p53 staining between the triple negative group[58.4%(66/113)positive] and the control group [41.7%(20/48) positive] (P＞0.05).The median time of follow-up was 24 months,the loss was 5 cases, 10 cases (9.3%, 10/108) had local recurrence and metastasis,and 8 cases (7.4%,8/108) died from breast cancer metastases,2-year survival rate was 96.2% in the triple negative group.There was no significant difference in local recurrence and survival time between the triple negative group and the control group (P＞0.05). Conclusions The incidence of triple negative breast cancer is higher than other data reported. Triple negative breast cancer exhibits the same clinical pathological features compared with ER-/PR-/HER-2 + subtypes,and the prognosis is similar to the controls.

Objective To explore the relative factors of aggressive behaviors in inpatients with schizophrenic.Methods 178 cases of continuously admitted schizophrenic patients were divided into attack group and non aggressive group according to the aggressive behavior of preadmission.Single factor analysis and multi factor regression analysis was applied to two groups in situation(such as age,gender,education level,course of disease,past aggressive behaviors and so on),Brief Psychiatric Rating Scale (BPRS) and Eysenck Personality Questionnaire (EPQ).Results By single factor analysis,attack group had significantly longer course of disease(7.73±6.67) than non aggressive group (5.22 ± 5.47,t =2.631,P＜ 0.01).The score of hostile suspicious factor in BPRS (13.73 ± 3.098) in attack group was significantly higher than that in nonaggressive group(11.47±3.93) (t=4.063,P＜ 0.01),but anxiety factor (7.18± 3.583) was significantly lower than that in nonaggressive group (8.70 ± 3.89) (t=2.679,P＜0.01).The score of E scale of EPQ(11.99±4.340) in attack group was significantly higher than that in nonaggressive group(10.67±4.293) (t=1.990,P＜0.01).Attack group's proportion of patients of previous attacks (71.1％) was significantly higher than that in non aggressive group (16.0％),(x2 =39.082,P＜ 0.01).(2) Logistic analysis showed that hostile suspicious factor in BPRS and past aggressive behaviors entered the regression equation.Condusions Aggressive behavior in schizophrenic patients occurs mainly with psychiatric symptoms and the past history of aggressive behavior.The patients should be treated actively to control the symptoms and prevent the disease recurrence.

Objective To prospectively study the relation between transforming growth factor beta-1 (TGF-?_1), V_(20) and lung function (PFTs) and radiation pneumonia (RP), as well as to set up a prediction model of RP. Methods From Jan 2004 to Dec 2005, 121 valid patients with esophageal carcinoma or lung cancer were treated with conventional thorax radiotherapy(RT) by 15 MV X-ray beams to a total D_T 60-68 Gy over 30-34 fractions in 42-46 days. All patients received chest CT scanning before RT. Dose volume his- togram(DVH) and V_(20) were obtained through 3-dimensional TPS. Serum TGF-?_1 and PFTs of the patients were measured both before and after RT as well as on the 20th day after the beginning of RT. RP was diag- nosed basing on contrasted CT and clinical symptoms. Results RP was diagnosed in 32 of all 121 pa- tients. The results of Logistic Regression Statistic showed that V_(20) and TGF-?_1 ratio (after RT/before RT) significantly influenced the incidence of RP. Patients with V_(20)≥30% had more RP than patients with V_(20)
