Objective To investigate the streptomycin(SM)-resistance of Mycobacterium tuberculosis (MTB) in urine and to examine their relationships with the mutation of rspL gene. Methods 47 strains of MTB were isolated from the urine of patients with renal tuberculosis.The mutation of rspL gene were analyzed by PCR-SSCP with silver-staining,and the strains were tested for the sensitivity to streptomycin. Results All the 47 strains had positive expression of rspL gene of MTB,with 28 SM-resistant and 19 SM-sensitive.Among the 28 SM-resistence strains 19(68%) had rspL gene mutation by SSCP testing.The 19 strains of SM-sensitive had no mutation. Conclusions Detecting mutation of MTB rspL gene in urine by PCR-SSCP can rapidly and exactly identify the MTB's sensitivity to streptomycin,which is significantly important in clinical treatment of anti-tuberculosis.

Objective To evaluate the effect of remifentanil on mean arterial pressure (MAP), heart rate (HR) and QTc interval during tracheal intubation of general anesthesia patients. Methods Seventy-five ASA Ⅰ -Ⅱ grade patients were selected and allocated to receive either saline (group C), remifentanil 0.50 μg/kg (group R1) or remifentanil 0.75 μg/kg(group R2) by random digits table with 25 cases in each, they were administrated as a bolus intravenous, followed by a continuous infusion at 0.10 μg/ (kg·min), 1 min before laryngoscopy. All patients received fentanyl 3 μg/kg,propofol 1.0 - 1.5 mg/kg and vecuronium 0.1 mg/kg. The ECG.MAP and HR were recorded prior to induction of anesthesia (T0), 2 min following the start of drug intravenous of fentanyl and propofol with vecuronium (T1), 1 min following remifentanil or saline (T2), before laryngoscopy(T3), 30 s (T4), 2 min (T5) and 4 min (T6) after intubation. Results The QTc interval was significantly prolonged immediately following intubation in group C and group R1, but it remained stable in group R2, compared with the QTc interval just before laryngoscopy. In group R2, QTc interval was significantly shorter at T4-T6 compared to group C(P＜ 0.05 or ＜ 0.01). QTc interval significantly increased from baseline at T4 in group R1 and T4-T6 in group C (P＜ 0.05 or ＜ 0.01). The number of patients with QTc interval ＞ 440 ms were significantly greater immediately following tracheal intubation in group C than that in group R2 [44% (11/25) vs. 12% (3/25)] (P ＜ 0.05). Conclusions QTc interval increases following tracheal intubation during induction of anesthesia using fentanyl and propofol. Intravenous of remifentanil attenuates the QTc interval prolongation associated with tracheal intubation. In addition, remifentanil decreases the hemodynamic responses to tracheal intubation.

Objective To explore the value of biomechanics parameter of rabbit abdominal aortic atheroma using velocity vector imaging(VVI).Methods Ten of 45 male New Zealand rabbits were chosen as normal control group randomly,the rest experimental rabbits were made atheromatous plaque model.The rabbits were examined by two-dimensional ultrasound and VVI respectively.The intima-media thickness(IMT) or thickness of plaques of abdominal aorta 1 cm from right renal artery branch were recorded.Maximum tangential velocity,strain and strain rate of IMT or plaques were measured using VVI.Then the rabbits were killed for pathological and immuno-histochemical examination.Results Based on pathology,the rabbites were divided into 4 groups:control group(group A,n=10),group of pathological endometrial thickening(group B,n=9),group of thick fibrous cap atheromatous plaques (group C,n=15) and group of thin fibrous cap atheromatous plaques (group D,n=11).The difference of plaques thickness and biochemical indicators had no statistically significant between group B and C(P>0.05),both bigger than group A and B (P<0.05).The difference of Vmax,Smax and SRmax had statistically significant each group(P<0.05).With Vmax>0.46×10-2 cm/s,Smax>0.37%,SRmax>1.415×10-2 s-1 to find the vulnerable plaques,the sensitivity were 75.0%,84.4%,84.4% respectively,specificity were 70.8%,91.7%,83.3% respectively.Conclusions VVI can identify plaque biomechanics parameter of different progression periods,which is expected to be a reliable method to find vulnerable plaques earlier in clinic.
