Background and purpose: One of the main mechanism of chemotherapy is inducing tuomr apoptosis. Molecular imaging can allow noninvasively and dynamically monitor tumor apoptosis in vivo, and help to drug screening and therapeutic evaluation. The purpose of this study was to evaluate the feasibility of 18F-SFB-Annexin B1 in detecting apoptosis at an early phase after chemotheraphy. Methods:Annexin B1 was labeled with 18F using SFB as a chelating agent. Tissue distribution of 18F-SFB-Annexin B1 was studied in healthy mice by the dissection method. W256 tumor-bearing rats were injected with 18F-SFB-Annexin B1 intravenously at 24 h after the treatment of cyclophosphamide (CTX 200 mg/kg) or saline. Then imaging was acquired at 1, 2, 3, and 4 h postinjection on a PET/CT, and the tumor-to-muscle ratio of SUVmax (T/M) and the AI from TUNEL testing were compared. Results: 18F-SFB-Annexin B1 had a radiochemical pruity (RCP)>95%. Biodistribution of this probe showed a predominant uptake in the kidney, then was liver, spleen, and myocardium, rapid clearance from blood and urinary was observed. The radios of T/M were 4.38±0.56, 6.75±1.16, 6.44±1.12, 4.81±0.17, respectively at 1, 2, 3, 4 h post injection of the chemotherapy group, much higher than that of the saline group (2.35±0.14, 2.99±0.55, 3.04±0.41, 2.33±0.47, respectively). The differences between the two groups were significant (F=23.790, 16.913, 14.046, 77.517, respectively, all P<0.05). TUNEL staining revealed that chemotherapy treatment significantly increased the percentage of apoptosis cells with an AI of (21.00±0.04)%in the chemotherapy group, higher than that in the saline group (8.58±0.01)%, the difference was significant (F=21.539, P<0.05). The radios of T/M were significantly correlated with the values of AI (r=0.91, P<0.05). Conclusion: 18F-SFB-Annexin B1 can be used to apoptosis imaging and early therapeutic evaluation in vivo because it can reflect apoptosis at an early stage after chemotheraphy.

Objective To study epidemiology, clinical findings, diagnosis and treatment of sepsis caused by Vibrio vulnificus. Method Patientss with Vibrio vulnificus sepsis were collected from 1995 to 2008. The medical records including epidemiological and clinical data were analyzed. Results The male-to-female ratio of 34cases was 4.7:1 and 76. 5% of these patients suffered from chronic liver disease. Most patients occurred from April to October with signs of abrupt fever, characteristic cutaneous lesions, hypotension and progressive multiple organ disfunction syndrome (MODS). The mortality was over 47.1% . The criteria proposed for early diagnosis of Vibrio vulnificus sepsis were abrupt onset with fever during the period from April to November, characteristic cutaneous lesions, such as the most commonly occurred haemorrhagic bullae on the extremities or even extensive necrosis of skin and muscular tissue, progressive hypotension or shock accompanied by MODS, pre-existing liver disease or chronic abuse of alcohol, and consumption of raw seafood or exposure to seawater within 12 week. Early administration of the third-generation cephalosporins with the quinolones in full dosage, aggressive wound debridement,appropriate dermoplasty and supportive care contribute to a better outcome. Conclusions Vibrio vulnificus sepsis progresses rapidly with high mortality. Early diagnosis, rapid treatment with prompt antibiotics and aggressive surgery treatment are very important to improve the outcome.

Objective To study the factors influenceing patients' family members to make own relative fac-tors patients' families making decision on refusal of cardiopulmonary resuscitation (CPR) to the critical patients. Method Data were registered based on Utstein Style of 522 patients aged over 15 years, who subjected to in-hos-pital cardiac arrest(CA) in Department of Emergency of The First Affiliated Hospital of Wenzhou Medical College from January 2005 to December 2008. A total of 157 patients' family made refusal decision among the 522 pa-tients, who belonged to the refusal group, and others belonged to the attempt resuscitation group. The associated factors included age, sex, marriage, household register, cause of CA, underlying diseases, capability of activity before CA, life supported with mechanical ventilation, and administration of pressor agents. The refusal decisions were evaluated by using univariate Logistical regression analysis, and then the statistical significant variables were analyzed by using muhivanate Logistical regression analysis. Results Age, household register, cause of CA(car-diac or traumatic),stroke, sudden death, cancer, capability of activity before CA, life supported with mechanical ventilation,and administration of pressor agents were the important factors of making refusal decision (P < 0.01), but sexes or marriage was insignificant related to the refusal decision (P > 0. O5). The independent risk factors re-lated to refusal decision were age (P = 0.034),cancer (P = 0.006),stroke (P = 0.003), and life supported with mechanical ventilation (P = 0.000) in multivariate Logistical regression analysis, but the protective factors were sudden death (P =0.000),cardiac CA (P =0.020) and traumatic CA(P =0.000). Conclusions Age over 60 years, cancer, stroke, and life suppoted with assisted ventilation before CA were factors associated with re-fusal decision making, yet sudden death, cardiac CA and traumatic CA were factors of accepting CPR.

Objective To investigate the changes of tissue factor(TF)and tissue factor pathway inhibitor(TFPI)at different time points after in-hospital eardiopulmonary resuscitation(CPR).and to explore the role of TF and TFPI in CPR.Method From September 2005 to September 2007,24 patients,who suffered from cardiac arrest,were selected from the of emergency medicine department,The First Affiliated Hospital,Wenzhou Medical College.The selected patients were older than 16 years old and had identified cardial :arrest time.All patients were randomly classified into two groups:those who had retum of spontaneous circulation(ROSC)(n:12)and those mthom ROSC(n=12).Ten normal healthy volunteers served as control subjects(n=10).Etiology of the car.diac arrest and clinical characteristics during eardiopulmomry resuscitation were emestered.Serial levels of"IF and TFPI at different time points of 30 min,60 min,6 h,24 h,48 h after CPR were measured by enzyme linked immunosorbent assay(ELISA)after eardarrest and CPR.Data Were expressed as mean±standard deviation twotailed t test and ANOVA and four flod table chi-square test were used for eomparisoll in SPSS 11.5 software,and chaangs were considered as statistically significant if P value was less than 0.05.Results Inpatients with ROSC.TF obviously increased at 30 min after CPR.reached peak at 6 h.1F levels in patients without ROSC wer higher compared to those of the control group and ROSC at the same time point.The levels of TPFI had no significantly differentce at 50 min after CPR,and TFPI,obviously elevated at 60 min after CPR in ROSC group compared to those ofthe control group and without-ROSC group.In comparison with control group,the ratio of TF/FPI at 30 min after CPR in without-ROSC group and ROSC group were marked elevated.The ratio of in without-ROSC group showed marked devations eompare,t to that of ROSC group.In R()sC group.the ratio of THFI peaked at 6 h after CPR and descended a after CPR.Conclusions'11le 1F and TFPI level8 after CPR in patients with in-hospital cardiac obviously increase.The levels of TF and TF/TFPI at 30 min after CPR can be used for predicting the prognosis of patients with in-hospital cardiac arrest.

AIM To study the effects of nalox-one on plasma endothelin-1 and nitric oxide during myocardiac ischemia-reperfusion ( I/R ) injury. METHODS Using myocardiac ischemia models and myocardiac ischemia -reperfusion injury models that was made by means of ligating sinistra corona-ria arteria,to investigate the change of plasma ET-1 and NO during I/R injury, and after the protection and treatment with naloxone,an antagonist of opoid receptor. 40 New Zealand rabbits were randomly assigned to 4 groupsCischemia group, nalox-one protection group, naloxone treatment group and ischemia-reperfusion group, 10 in each group). The blood was phlebotomized at different time in each group. The concentration of ET-1 was detected with radioimmunology method and NO with nitrate reductase method. RESULTS The levels of ET-1 had the trend of improvement after ischemia and were at its peak at the end of 4 h, but the levels of NO were significantly decreased. The ET-1 levels were significantly improved after 0. 5-1 h of injury compared with that before ischemia (P 0. 05). The levels of NO decreased after injury , whereas its levels in naloxone protection group increased significantly compared with that before ischemia ( P 0.05). CONCLUSION Naloxone may effectively reduce the level of ET-1 and enhance the level of NO after myocardiac ischemia and during I/R injury; whereby it decreases the injury to vascular and myocardium.

AIM: To observe the effects of Salvia miltiorrhiza Bge (SMB) on left ventricular hypertrophy(LVH)in spontaneously hypertensive rats (SHR) and the expression of c-fos. METHODS: 18 SHRs in 8 weeks old were divided into three groups at random. SMB or distilled water(1 g?kg -1?d -1)was injected intraperitoneally to two groups for 10 weeks. Systolic blood pressure (SBP) and left ventricular mass index(LVMI)were measured. HE,VG and immunohistochemical staining combined with computed morphometry were used to evaluated the cardiomyocyte size and diameter, the collagen volume fraction(CVF), perivascular circumferential area (PVCA) and c-fos expression in the left ventricular tissue. RESULTS: Compared with 8-week-old rats, the SBP, LVMI, cardiomyocyte size and diameter, CVF, PCVA, c-fos expression increased markedly in the 18th week of SHRs. The LVH stopped and c-fos expression decreased whereas SBP changed slightly in animals treated with SMB. CONCLUSION: Chronic treatment with SMB can inhibit the development of LVH in SHR, which is probably related to the decease of cardiac c-fos.

Objective To survey cervical myoelectric signals during craniocervical flexion, neutral and extension postures, and to explore the evidence that proper head position can alleviate cervical muscle fatigue in a lateral recumbent position. Methods Surface electromyography (sEMG) signals were detected from the sternocleidomastoid, upper trapezius and erector spinae muscles of 30 young subjects bilaterally during craniocervical flexion,neutral and extension postures in the left lateral recumbent position. The integrated trace area (IEMG) and median frequency (MF) were estimated. Results The average IEMG of the sternocleidomastoid muscles was significantly lower in flexion than in extension bilaterally. The average IEMG of the erector spinae muscles was lower in extension than in flexion bilaterally, and the difference was again significant. The IEMGs of the upper trapezius muscle showed no significant difference on average in the three postures bilaterally. There was no significant MF difference in any of the muscles. Conclusions The muscles in the cervical back were less activated during craniocervical extension in a lateral recumbent position. A little cranicocervical extension is optimal while resting in a lateral recumbent position.
