Objective To explore the clinical and imaging characteristics of traumatic carotid cavernous fistula(TCCF) with hemorrhage.Methods There were thirteen cases of TCCF underwent car accidents combined with epistaxis or intracranial hemorrhage between 1990 and 2000.Their clinical symptoms,CT,MR,and digital substract angiogram(DSA) were retrospectively analysed.Results There were special clinical and imaging characteristics in TCCF.Small amount of epistaxis and isolateral loss of sight might be found in cases with epistaxis at early stage,but delayed fatal and massive epistaxis occured at various time after trauma.Cranial base fracture and pseudoaneurysm were special imaging signs.In the TCCF cases with intracranial hemorrhage,prominent and tortuose cortical drainage veins might be found.And pseudoaneurysm at posterio-lateral wall of cavernous sinus might be another special imaging sign.Conclusion Small amount of epistaxis at early stage,cranial base fracture,pseudoaneurysm,prominence and tortuosity of cortical veins are characteristic diagnostic references for TCCF with hemorrhage.Emergent DSA examination at early stage should be regarded as a key step for diagnosis and treatment.

In the experimental study on the electrophysiology and functions of heart in the animal, the thorax should be opened to expose the heart, at the same time natural breathing is maintained instead of artificial breathing. The key procedure of this new method is to avoid injuring the pleural cavity, so pneumothorax can be prevented. By means of this new method some subject studies have been finished.

OBJECTIVE: To determine the vaginal flora distribution in cervical cancer patients and the common pathogenic bacteria as well as drug resistance, and to explore the correlation of vaginal bacterial infection and high-risk human papillomavirus (HR-HPV) infection with cervical cancer.
 METHODS: A total of 216 patients with cervical cancer served as an experimental group, and 53 patients with chronic cervicitis served as a control group. The patients' vaginal fluid in two groups was collected before the treatment for regular bacterial culture and HPV testing. The distribution and drug resistance of bacteria in two groups of vaginal secretion were observed, and the correlation of the bacterial infection and HPV infection with the cervical cancer was analyzed.
 RESULTS: The gram-negative and gram-positive bacteria accounted for 74.38% and 21.49% in the experimental group, respectively. They were mainly resistant to ampicillin and piperacillin or penicillin and erythromycin. The gram-negative and gram-positive bacteria accounted for 42.31% and 23.08% in the control group, respectively. They were mainly resistant to ampicillin and piperacillin or penicillin. HPV-positive rates in the experiment group and the control group were 60.65% and 41.51%, respectively. There were 70 patients (32.41%) and 12 patients (22.64%) with both bacterial infection and HPV-positive infection in the experiment group and the control group, respectively. However, there was no statistical difference between the 2 groups (P>0.05). 
 CONCLUSION Escherichia coli are the main pathogen in cervical cancer and they are highly resistant to antibiotics. Bacterial infection in genital tract is not an efficient cofactor for HPV to cause the cervical cancer.
