Objective To evaluate the urine cytology silver staining combined with ultrasonography（USG）in the detection of bladder transitional cell carcinoma （TCC） recurrence after transurethral resection of bladder tumor（TURBT）in terms of sensitivity and specificity. Methods Cystoscopy was used as “gold standard”. Urine cytology combined with USG or cystoscopy was measured separately and blindly. AgNORs protein stained by silver were used in cytology with Kappa of inter-observers 0.81. For the USG, the patients were scanned with trans-rectal probe with Kappa of inter-observers 0.76. The results of urine cytology combined with USG （Positive when urine cytology and/or USG positive. Negative when both urine cytology and USG negative） were compared with “gold standard”. Results The 148 consecutive superficial TCC patients with TURBT one year previously were included in this study. Fifty seven recurrenced cases were detected. Recurrence rate was 38.51%. The sensitivity and specificity of urine cytology silver stain were 89.47% （95% CI 0.82 to 0.98） and 87.91% （95% CI 0.81 to 0.95）. Area under ROC curve was 82.22%. The sensitivity and specificity of USG were 57.90% （95% CI 0.45 to 0.71 ） and 90. 11% （ 95% CI 0.84 to 0.96）. Area under ROC curve was 73.13% . The sensitivity was improved to 94. 74% （95% CI 0.89 to 1.00） when cytology combined with USG. But specificity decreased to 84. 62% （95% CI 0.77 to 0.92 ）. Area under ROC curve was improved to 98.28%. Conclusions Urine cytology silver stain combined with USG improves the high sensitivity for follow-up TCC patients after TURBT. The non-invasive protocol is suggested.

目的:探讨B超检查对急腹症的临床应用价值。方法:回顾性分析326例急腹症的超声表现并与手术后、病理诊断以及随访结果进行对照。结果:326例急腹症中以急性胆囊炎、输尿管结石、急性阑尾炎以及妇科急症常见,共289例,占88％,其他急腹症37例,占12％。经手术和病理证实217例,109例临床随访证实。超声符台率89.9％。结论:B超检查对急腹症的早期诊断以及鉴别诊断具有重要临床意义,是急腹症首选的诊断方法。
目的 评价B超引导下核心针活检术（CNB）对不可触及的乳腺病变（NPBL）的诊断价值。方法 采用18G Tru-cut针结合活检枪对88例患者的96个NPBL行B超引导下CNB，并与切除活检病理结果比较。结果 NPBL大小4～23mm（平均13.1mm）。在CNB中，86个为良性，2个为可疑恶性，6个为恶性，2个取材不良。在切除活检中9个为恶性，87个为良性。CNB可疑恶变的2个NPBL均为恶性，1个恶性NPBL误诊为乳腺腺病，取材不良的2个NPBL均为良性。本组NPBL中恶性病变占9.38%（9/96），B超引导下CNB对NPBL的良恶性诊断正确率为98.94%（93/94），诊断乳腺癌的敏感性为88.89%（8/9），特异性为100%（8/8），良性病变的病理诊断符合率为97.70%（85/87），取材不良为2.08%（2/96）。结论 B超引导下CNB对NPBL的诊断具有较高的敏感性和特异性，结果准确可靠。
Objective To investigate the significance of urinary trypsinogen-2 dipstick test and the ratio of urinary amylase to urinary creatinine for the diagnosis of acute pancreatitis(AP).Methods A total of 57 consecutive patients who were suspected as AP presenting with abdominal pain at the emergency department experienced the test of serum and urinary amylase, urinary creatinine assay, urinary trypsinogen-2 dipstick and ultrasonography. Results There were 18 patients diagnosed as acute pancreatitis, the serum amylase assay had a sensitivity of 88.9 percent (cutoff value, 300 U per liter) and a specificity of 87.2 percent, the sensitivity and specificity of the urinary amylase assay and the ratio of urinary amylase to urinary creatinine were 88.9 (cutoff value, 2000 U per liter), 94.4 (cutoff value, 120 U per mmol Cr), 84.6 and 89.7 percent, respectively. The sensitivity and specificity of the urinary trypsinogen-2 test strip were 94.4 and 92.3 percent. The sensitivity of the ultrasonography were 88.9 percent. Conclusion Urinary trypsinogen-2 dipstick test is a good index for the diagnosis of AP. The ratio of urinary amylase to urinary creatinine is also a useful index and may be better than urinary amylase for the diagnosis of AP.

ObjectiveTo investigate the therapeutic effect of B ultrasound-guided percutaneous catheter drainage combined with veno-venous hemofiltration at different time points and multi-site in treatment of hyperlipidemic severe acute pancreatitis (HL-SAP). MethodsThe clinical data of 34 patients with HL-SAP initially underwent B ultrasound-guided percutaneous catheter drainage combined with veno-venous hemofiltration at different time points and multi-site from January 2010 to June 2014 were retrospectively analyzed. According to the different of the onset to treatment time, 34 cases were divided into the≤24 h group and > 24 h group. The serum platelet activating factor (PAF) and triglyceride (TG) at the time of admission and after admission 1, 3, 5, 7, and 10 days were detected, and the hospitalization time, mortality, and the rate of conversion to open surgery were observed. ResultsThe levels of PAF and TG in the both groups tended to gradually decrease with different degrees, were significantly lower than that the before treatment (P < 0.05), and the decline of PAF and TG in≤24 h group were more significant than > 24 h group. The hospitalization time, mortality, and the rate of conversion to open surgery in the≤24 h group were significantly lower than those of the > 24 h group (P < 0.05). ConclusionThe early using of B ultrasound-guided percutaneous catheter drainage combined with veno-venous hemofiltration at different time points and multi-site would have a beneficial impact on the management of HL-SAP and complications.
