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.

To assess the effect of prostaglandin E_1(PGE_1)on renal blood flow and serum endothelin of liver recipients.Methods PGE_1 was administered in 38 liver recipients at the dose of 0.6?g?kg~(-1)?h~(-1)during liver transplantation and every day after operation.The effects of PGE_1 on serum endothelin concentration and creatinine(Cr)were observed and these indexes were compared with those in the control group(n=18).The renal blood flow resistance indexes(RI)were measured by Doppler ultrasound.Results Cr and RI were significantly lower in PGE1=treated group than those in the control group.PGE_1-treated group also showed a significantly lower serum endothelin concen- tration.Conclusion Administration of PGE_1 in liver recipients can significantly improve the early re- nal function by reducing serum endothelin concentration and dilating renal blood vessels.

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.

?AIM: To retrospectively analyze the surgical strategies and outcome of traumatic lens dislocation.?METHODS: Retrospective study. Clinical data of 105 cases ( 105 eyes ) diagnosed with traumatic lens dislocation from April to June 2014 in our hospital were recruited. According to position of dislocated lens and complicated situations, different surgical approaches were performed, including intracapsular lens extraction, phacoemulsification, vitrectomy through pars plana and lensectomy. Meanwhile, vitreo-retinal or anti-glaucoma surgeries were performed in complicated cases. Preoperative and postoperative LogMar ( Logarithm of the Minimum Angle of Resolution ) visual acuity were compared by paired t-test. Perioperative complications including expulsive choroidal hemorrhages and recurrent retinal detachment were recorded and assessed.?RESULTS: All 105 dislocated lenses were removed completely. Visual acuity of 91 eyes ( 86. 7%) were significantly improved postoperatively. The visual acuity of most patients was 0. 1-0. 3 ( 42 eyes, 40. 0%) and 1 patient’s visual acuity with lens subluxation reached more than 0. 8 postoperatively. Expulsive choroidal hemorrhages occurred in 1 eye intraoperatively and 1 eye postoperatively. Recurrent retinal detachment was observed in 2 eyes postoperatively.? CONCLUSION: According to position of the lens dislocation, personalized surgery strategy is critical for therapy of traumatic lens dislocation. Expulsive choroidal hemorrhage is one of most several complications and should be managed properly.

Objective To quantitatively analyze and compare the texture features of thermal and chemical lesions on the porcine striated muscle, in vitro extracted from high-frequency ultrasonograms using computer-assisted image analysis technique, and to investigate the application values. Methods The thermal lesion and chemical lesion were induced in vitro in porcine striated muscle by microwave ablation and anhydrous acetic acid injection, respectively. The two dimension (2D) ultrasonographic ifndings were qualitatively compared between the groups of thermal and chemical lesion models, in which eight textural features in geometric mathematics extracted from 2D ultrasonograms were quantitatively analyzed by a technique of computer-assisted image analysis named multiscale decomposition method of echo intensity of interface relfections. Results As expected, microwave ablation and anhydrous acetic acid caused signiifcant changes of several texture features extracted from ultrasonograms. There were significant differences between the normal group and microwave ablation group in grayscale mean (Mean), irregularity (IRGL) and periodicity of distribution (POD) as follows (Mean: 1.9143±0.2914 vs 1.2334±0.3357, t=-5.306, P=0.000; IRGL: 0.5577±0.0334 vs 0.5092±0.0459, t=-2.957, P=0.007; POD: 0.000 27±0.000 005 vs 0.000 29±0.000 008, t=4.782, P=0.000). There were signiifcant differences between the normal group and anhydrous acetic acid injection group in number of blobs (NOB), size of blobs (SOB) and periodicity of distribution (POD) as follows (NOB: 51.0324±13.6998 vs 31.6042±4.8315, t=4.633, P=0.000; SOB:16.4843±3.9349 vs 25.6230±2.3555, t=6.903, P=0.000;POD:0.000 26±0.000 015 vs 0.000 29±0.000 008, t=-4.459, P=0.000). For each group of injured regions, there were significant differences between the microwave ablation group and anhydrous acetic acid injection group in Mean, IRGL, NOB and SOB as follows (Mean: 1.2664±0.2688 vs 1.9143±0.2914, t=-5.661, P=0.000; IRGL: 0.5220±0.0422 vs 0.5577±0.0334, t=-2.295, P=0.032;NOB:51.0324±13.6998 vs 34.5856±2.6362, t=4.048, P=0.000;SOB:16.4843±3.9349 vs 25.3176±2.3501, t=-6.676, P=0.000). Conclusion Technique of computer-assisted image analysis named multiscale decomposition method of echo intensity of interface relfections, based on multiscale blob features extraction, was useful to differentiate ultrasonic texture features between the groups injured in our study, which established quantitative muscle ultrasound as a practical and reliable tool for the muscle injury diagnosis to distinguish the structural changes induced by different physiochemical factors.
