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.

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.

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

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.

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 compare pharmacodynamics of vecuronium administered according to body surface area and body weight during general anesthesia.Methods Forty ASA Ⅰ or Ⅱ patients,aged 18-64 yr,weighing 40-85 kg,undergoing general anesthesia,were randomly divided into 2 group ( n =20 each ).The patients received vecuronium 2× ED95 based on body weight (group W) or based on body surface area (group S).Anesthesia was induced with propofol 2 mg/kg,fentanyl 3 μg/kg and vecuronium 0.1 mg/kg ( group W) or 2.824 mg/m2 (group S).The patients was tracheal intubated and mechanically ventilated when the maximal depression of T1 was achieved.PET CO2 was maintained at 35-45 mm Hg and BIS value was maintained at 40-50.The intubation condition was evaluated using Cooper's score.The onset time,maximal depression of T1,duration of clinical action,recovery index,duration of pharmacological action and amount of vecuronium consumed were recorded.The coefficient of variation for all the indexes mentioned above was calculated.Results There was no significant difference in the coefficient of variation for intubation condition,onset time,duration of clinical action,recovery index,and duration of pharmacological action between the two groups ( P ＞ 0.05).Compared with group W,the coefficient of variation for the maximal depression of T1 and amount of vecuronium consumed were significantly decreased in group S ( P ＜ 0.05).Conclusion Vecuronium 2 × ED95 administered according to body surface area can reduce the individual variation in pharmacodynamics during general anesthesia.

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 observe the intervention with electroacupuncture(EA) through regulating protein kinase(MAPK/ERK) pathway for cerebral ischemia rats.Methods SD rats were randomized into pseudo-operation group,model group and EA group.And the three groups were divided into 2-hour,one-day and 3-day subgroups according to the observation time.Focal cerebral ischemia(FCI) rat models were established by middle cerebral artery occlusion(MCAO) with heat-coagulation method.EA group received EA on Baihui(GV20) and Dazhui(GV14),qd,for 2 hours,one day and 3 days respectively.The learning and memory abilities of the rats in Y maze test and their neuroethological score were observed.Immunohistochemical method was used to observe the expression of phosphorylated extracellular signal-regulated kinase(p-ERK) after ischemia in CA1 area and CA3 area.Results In the model group,the neuroethological score was markedly increased,time for arriving the safe area in Y maze was prolonged(P
