Objective To explore the clinical characteristics and effects of thrombolytic and anti coagulation treatment in over 70 year old patients with pulmonary thromb embolism(PTE). Methods The clinical findings, diagnostic techniques, effects of thrombolytic therapy and anti coagulation in 58 over 70 year old patients with PTE were analyzed retrospectively. Results Deep venous thrombosis (DVT) in lower limbs (74 1%) was the most common thrombolism prone factors in our study. Limitation of movement and long term stay in bed due to a variety of causes were in the next place. The clinical findings were atypical, associated with a false diagnostic ratio of 46 5% in elderly patients with PTE. Undefined causal and different degree of dyspnea along with sudden and persistent hypoxemia were the main characteristics. Spiral CT and radioactive nuclear ventilation perfusion scan were important methods for diagnosis of PTE with positive finding of 95 7% and 62 5%, respectively. The effective and cure rate of thrombolytic therapy combined with anti coagulation, anti coagulation and anti platelet therapy was 91 3%, 75 8%, 0 and 47 8%, 17 2%, 0, respectively. Conclusions The most common risk factors of PTE in the elderly was DVT and the long term stay in bed or stay without active moving. The clinical symptoms were not only atypical but also variable. Thrombolytic with anti coagulation therapy is safe and effective, but anti platelet coagulation alone is not benefit.

To analysis the reason of the arguments of “Sexual hallucinations” or “Sexual harassment”between clinicians and patients,and find out how to prevent its happening.Methods:Base on clinical case about patients complaints that clinicians sexually assault,review and analysis the prtinent literatures.Results:Sexual hallucinations is a complication following anesthesia with psychotropic drugs,it 's easy to be misunderstand as Sexual harassment and result in allegations of sexual misconduct between patient and clinician.Conclusion:Clinicians need to be aware that sexual hallucinations to occur during sedation or after anesthesia,to protect themselves against the accusations of sexual harassment,the practitioner should never be unchaperoned with a patient of the opposite sex during sedation or anesthesia.

BACKGROUND:It is wel known that long-term aerobic exercise aleviates renal dysfunction in spontaneously hypertensive rats. However, the underlying molecular mechanism remains unclear.
OBJECTIVE:To investigate the effect of long-term aerobic exercise on endogenous formation of hydrogensulfide in the kidney of spontaneously hypertensive rats.
METHODS:Rat models of long-term aerobic exercise were established and randomly assigned to four groups: Wistar-Kyoto (WKY) rat static group, WKY rat exercise group, spontaneously hypertensive rat static group and spontaneously hypertensive rat exercise group. Moderate-intensity exercise on treadmil was given for 12 weeks. At 24 hours after model establishment, weight was weighted. Blood pressure was detected in the caudal artery. Blood and urine were colected for measuring biochemical indicators related to kidney functions. The degree of glomerular sclerosis was observed. Hydrogen sulfide production activity was detected in the kidney. RT-PCR was used to detect mRNA expression levels of hydrogen sulfide production-related enzymes. Simultaneously, oxidative stress of the kidney was observed.
RESULTS AND CONCLUSION:(1) Long-term aerobic exercise obviously reduced body mass, systolic blood pressure and diastolic blood pressure, increased glomerular filtration rate and renal blood flow, decreased serum creatinine and urea nitrogen levels, urinary albumin levels, significantly reduced glomerular sclerosis score, increased hydrogen sulfide content in plasma and the rate of hydrogen sulfide formation in renal tissue, up-regulated cystathionine γ-lyase expression, obviously diminished malondialdehyde content in serum and kidney, and remarkably increasedthereduced glutathione and oxidized glutathione ratio in spontaneously hypertensive rats. (2) Results indicated that long-term aerobic exercise could increase the generation of endogenous hydrogen sulfide in kidney, lessen oxidative stress in the kidney, and amelioraterenal dysfunction in spontaneously hypertensive rats.

Objective To investigate the clinical and skeletal muscular pathological features of chronic progressive external ophthalmoplegia(CPEO).Methods The clinical and skeletal muscular pathological data of 6 patients with CPEO were analyzed retrospectively.Results All of the 6 patients onset were 4 to 18 years old.The first symptom was blepharoptosis.The clinical mainly manifestations were limited activity of eyeball,accompanied with limbs muscle fatigue,weakness and level elevatation of serum creatine kinase(CK).5 cases had myogenic changes in electromyography(EMG).The skeletal muscular pathological examination showed that the ragged red fibers(RRF)were scattered among the muscle fibers,and the deficient or absent of COX activity in many fibers.A few degenerating and necrotic fibers were observed in 4 cases.Lipid-drops were increased by oil red "O" stain in 3 cases.Electromicroscope showed that abnormal mitochondria increased in number and aggregated under sarcolemma or in cytoplasm.Crystalloid inclusion body could be observed.Conclusions The clinical mainly features of CPEO are external ophthalmoplegia and accompanied with limbs weakness.RRF and COX activity deficiency or absence according to skeletal muscle pathology can be suggest and support the diagnosis of CPEO.Gene sequencing based on skeletal muscle biopsy is necessary to make the final diagnosis of CPEO.

The main clinical symptoms of the patients are upper gastrointestinal tract haematemesis,hypersplenotrophy and hypersplenia.Most cases can be detected by ultrasonography,digital subtraction angiography(DSA),multislice CT(MSCT) or magnetic resonance angiography(MRA).Rex surgery,Hassab surgery or combination the shunt and disconnection combined operation et al are the preferred operation,therapy for children's cavernous transformation of portal vein will be further developed.The relevant literatures were collected in recent years to review the advancement of surgical therapy for children's cavernous transformation of portal vein.

BACKGROUND:Presently used pulmonary vein antrum location methods mainly performed by three-dimensional electroanatomy combined with X-ray image or CT image fusion.These methods conducted vein antrum location and ablation by anatomy instructions.It is still poorly understood whether the ablation hit the key part of atrial fibrillation.OBJECTIVE:To explore the feasibility of catheter ablation guided by three-dimensional electroanatomic mapping system in conjunct with pulmonary vein antrum potential in patients with atrial fibrillation.DESIGN,TIME AND SETTING:The verification clinical study was performed at the Department of Cardiology of Jinan Fourth People's Hospital and Hebei People's Hospital from March 2007 to June 2009.PARTICIPANTS:Fifty-one patients with drugs refractory,paroxysmal atrial fibrillation were included.METHODS:All patients underwent circumferential pulmonary vein antrum ablation guided by three-dimensional electroanatomic mapping system (CARTO) in conjunct with pulmonary vein antrum potential with the endpoint of electrical isolation.Relevant parameters and ablation success rate were observed.MAIN OUTCOME MEASURES:Procedure-related parameters,such as procedure duration,fluoroscopy duration,cumulative success rate and complication were observed.RESULTS:Pulmonary veins were isolated in all 51 patients.The mean procedure duration,fluoroscopy time and radiofrequency ablation duration are respectively (207±36.7) minutes,(38.2±14.3) minutes,(56.4±15.7) minutes.After (17.5±3.8)-months follow-up,forty (78.4%) patients did not have recurrence of atrial fibrillation,atrial flutter or atrial tachycardia.No severe procedure-related complication had happened.CONCLUSION:Pulmonary vein antrum potential can be used as a landmark to define pulmonary vein antrum,that combined with CARTO system to guide pulmonary vein antrum ablation is effective,safety and feasible for catheter ablation of atrial fibrillation.
