ObjectiveTo evaluate the applicection value of ultrasonically guided percutaneous puncture and drainage of gallbladder (PPDG) in treating elderly patients with acute cholecystitis.MethodsThe clinical data of 59 elderly patients with acute cholecystitis treated by ultrasonically guided PPDG were retrospectively analyzed and compared with 37 patients treated by cholecystectomy or 13 cases by cholecystostomy.ResultsThe rates of complication and fatality and average hospital days were 32.4 ％ (12/37),5.4 ％ (2/37) and (25.4 ± 16.5 ) d in patients by cholecystectomy and 7.7％(1/13),7.7％(1/13) and (32.0± 12.5) d in patients by cholecystostomy,respectively,while the complication and mortality were not found in patients by ultrasonic ally guided PPDG with average hospitalization of(19.5 ±9.8)d. The rates of the complication and average hospital days were significantly higher in patients by cholecystectomy and cholecystostomy than in patients by ultrasonically guided PPDG (P＜0.05).ConclusionsUltrasonically guided PPDG is effective,safe and convenient for the treatment of acute cholecystitis in elderly patients.

Objective To evaluate the function and synchronization of left atrial in patients with chronic heart failure(CHF) by real-time three dimensional echocardiography (RT-3DE).MethodsThirty healthy controls and thirty-two patients with CHF were studied.The CHF were divided into group CHF1 with the normal of left ventricular filling pressure and group CHF2 with the elevated of that.From the volume-time curve of RT-3DE workstation,the maximum volume (LAVmax),the minimum volume (LAVmin),the volume before contraction (LAVp) of left atrial were acquired.Accordingly,the total,passive and active ejection fraction could be calculated.The synchronization parameters derived from RT3DE were the dispersion and maximum difference of time to minimum volume for left atrial segments (Tmsv- 16-SD,Tmsv 12-SD,Tmsv-6-SD,Tmsv- 16-Dif,Tmsv 12-Dif,Tmsv-6 Dif).The index of volume and time were corrected by the body surface area and interval of R-R,respectively.The correlation were analysed in them.Results ① All the index of volume before and after correction were gradually increasing from control to CHF2 group,but the LATEF,LAPEF and LAAEF were just the reverse,with all parameters had significant difference among total groups( P ＜0.01 ).②The synchronization parameters were significantly higher from control to CHF2 group( P ＜0.01 ).Comparing between two groups,no significant difference of the synchronization parameters were found between CHF1 group and CHF2 group ( P ＞ 0.05),except Tmsv-16-SD％ and Tmsv-16-Dif％ ( P ＜0.01 ).③The Tmsv-16-SD％ and Tmsv-16-Dif％ had a positive correlation with the index of volume and a negative correlation with the ejection fraction.The most significantly correlation parameters was LAVmaxI,with r =0.75 and P ＜0.01.ConclusionsThe function of left atrium are reduced in patients of CHF,there are dyssynchronization.The higher of the filling pressure of left ventricle,the lager of the dyssynchronization of left atrium.RT-3DE may paly important roles in the evaluation of function and synchronization of left atrium.

OBJECTIVETo observe the effect of Zhibai Dihuang Decoction (ZDD) on mRNA and protein expressions of transient receptor potential family vanilloid subtype 1 (TRPV1) and transient receptor potential family vanilloid subtype 5 (TRPV5) in Ureaplasma urealyticum (UU)-infected rat semens and spermatogenic cells, and to explore the pathomechanism of UU-infected infertility and the intervention of ZDD.

METHODSTotally 45 were randomly selected from 60 4-5 months old SD rats. UU testicular infected animal models were set up after bladder inoculation of UU suspension. The remaining 15 rats were simultaneously injected with normal saline as a normal control group. After a successful modeling, UU infected model rats were randomly divided into the model group, the azithromycin group, and the ZDD group, 15 in each group. Rats in the ZDD group were administered with ZDD at the daily dose of 1 g/kg by gastrogavage. Rats in the azithromycin group were administered with azithromycin suspension at the daily dose of 0. 105 mg/kg by gastrogavage. Equal volume of normal saline was administered to rats in the normal control group and the model group. All medication was performed once daily for 21 successive days. Testes and epididymis were extracted after rats were killed and UU positive rates were compared among all groups. Sperm cells were separated using a mechanical separation technique. Sperm motility parameters were detected using color sperm motion detection system. mRNA and protein expressions of TRPV1 and TRPV5 in spermatogenic cells were determined by real-time quantitative PCR and Western blot.

RESULTSThe UU positive rate was obviously higher in the model group than in the normal control group [(86.7% (13/15 cases) vs. 0] P < 0.05). It was lower in the ZDD group [33.3% (5/15 cases)] and the azithromycin group [26.7% (4/15 cases)] than in the model group (P < 0.05). Compared with the normal control group, class A and B sperms were reduced, the linear velocity and the average velocity were significantly lowered, mRNA and protein expressions of TRPV1 and TRPV5 in spermated genic cells significantly decreased in the model group (P < 0.05). Compared with the model group, class A and B sperms were increased, linear and curve velocities and the average velocity were significantly elevated, mRNA and protein expressions of TRPV1 and TRPV5 significantly increased in the ZDD group and the azithromycin group (P < 0.05, P < 0.01). Compared with azithromycin group, class A and B sperms were increased, the linear velocity and the average velocity were significantly elevated, mRNA and protein expressions of TRPV1 and TRPV5 significantly increased in the ZDD group (P < 0.05, P < 0.01).

CONCLUSIONZDD could fight against UU infection and elevate semen quality, which might be associated with up-regulating mRNA and protein expressions of TRPV1 and TRPV5 in spermatogenic cells.

Objective To discuss the value of 16-slice spiral CT urography in clinical diagnosis.Methods To compare the images between CR excretory urography,CT and MPR,which are the results of 26 cases who were examined by both CR and 16-slice spiral CT urography.Results From the comparison,it is found that the spiral CT urography images are better than that of the CR excertory urography,and at the same time,the relationship between the parenchyma of the renal,renal pelvis,ureter,bladder and the urinary organs and adjacent structures can be demonstrated clearly.Conclusion The scanning time of the spiral CT is shorter.The machine can not only reconstruct powerfully but also work out better images,and the result is better than CR excretory urography which can not detect some details in its images.Therefore CR excretory urogaphy can be replaced by 16-slice spiral CT urography regardless of its cost.

Objective：To study the toxicity mechanism(s) of ifosfamide(Ifo) in suspending cultured rat hepatocytes.Methods：Hepatocytes of adult rat were isolated using two-step perfusion method and cultured suspendingly. Cell viability,intracellular enzyme leakage, contents of sulfhydryl groups and MDA contents of hepatocytes were examined 3 hours after ifosfamide was administered at 5,10,20 mmol/L. Surface and ultrastructure of hepatocytes were also observed. Results：Cell viability and TSH,NPSH,PSH contents of hepatocytes significantly declined, and LDH,AST activities in media increased due to the leakage of intracellular enzymes. The decrease in PSH content was ascribed to depletion of TSH. The higher the dose was, the more serious these changes became. However, MDA contents of the hepatocytes were not found increased at any ifo dose groups. In pathological examination, “bulla" formation was found on the surface of the hepatocytes, deformation，swelling even vacuolation of mitochondria and dilation of rough，smooth endoplasmic reticulum were also observed. Conclusions：Ifo has toxic effect on suspending cultured rat hepatocytes. The decrease in sulfhydryl groups contributes to the hepatotoxicity induced by Ifo.
