ABSTRACT
@# Objective To evaluate the effect of contrast-enhanced transcranial Doppler (c-TCD) for detection of patent foramen ovale (PFO) comparing to transesophageal echocardiography (TEE). Methods 28 ischemic stroke patients with PFO detected with TEE were evaluated with TCD bubble study at rest and under Valsalva maneuver (VM). Results PFO was identified in 20 cases (71.43%) at rest by TCD bubble study. When VM was performed, PFO was detected in 24 cases (85.71%). There was no relevant in sensitivity of c-TCD with PFO size (P>0.05). Conclusion c-TCD is an excellent method for PFO identification with high sensibility while under VM. C-TCD can be used as a screening method for suspected PFO in patients with stroke test before TEE.
ABSTRACT
@#ObjectiveTo investigate the related factors of ischemic cerebrovascular diseases in patients with patent foramen ovale (PFO). Methods42 patients with PFO，aged ≤55 years old, with cerebral infarction or transient ischemic attack and treated with aspirin were involved. All patients were examined with transesophageal echocardiography. 6 cases relapsed and 36 cases did not. The size of PFO, serum fibrinogen level, and combination of atrial septal aneurysm (ASA) were compared. ResultsThey were followed up for (512.51±127.38) d. The serum fibrinogen level was (3.33±1.11) g/L in no relapse group, and was (4.40±1.49) g/L in relapse group （P=0.032）. There was not significant difference in the size of PFO (P=0.618) and combination ASA (P=0.554) between these groups. Logistic regression showed that patients with ischemic cerebrovascular diseases history involved in relapse (OR=46.913,95%CI:2.371～928.254), but the serum fibrinogen level did not （OR=2.656,95%CI:0.977～7.219）. ConclusionThe PFO patients with history of ischemic cerebrovascular diseases incline to relapse. It is not sure the influence of the serum fibrinogen level on it.

ABSTRACT
OBJECTIVE To discuss the risk of tuberculosis infection in a general hospital workers.METHODS In a cross-sectional survey,we studied purified protein derivative(PPD) test in exposure group and control group.(RESULTS) The positive rate of PPD test in the hospital workers was 84.1%,significantly higher than that in(controls)(52.1%,P0.05).The positive PPD in workers of respiratory(department) was 2.95 times higher than in those of other departments.CONCLUSIONS The(environment) of(hospital) is special.Tuberculosis infection threatens the health of hospital workers.So we suggest that hospital workers(improve) self-protective consciousness and actively prevent tuberculosis infection,especially for(internes) and(physicians) with negative PPD.
