RESUMEN
Objective To explore the diagnostic value of contrast-enhanced ultrasonic intravenous imaging and cholangiography in the diagnosis of malignant jaundice obstructive. Methods Forty three patients who were diagnosed with malignant obstructive jaundice by contrast-enhanced computed tomography and contrast-enhanced computed magnetic resonance imaging were enrolled in this study. All of them underwent conventional ultrasound, IV-CEUS and IC-CEUS. According to the results of operation, the diagnosis accuracies were compared among conventional ultrasound, IV-CEUS, IC-CEUS and IV- CEUS combined with IC-CEUS. Results Diagnostic accuracy by the conventional ultrasound , IV-CEUS , IC-CEUS and IV- CEUS combined with IC-CEUS were 72.1%(31/43), 83.7%(36/43), 81.4%(35/43) and 93.0%(40/43), respectively. IV- CEUS combined with IC-CEUS was superior to the conventional ultrasound (P = 0.021). There were no significant differences when the conventional ultrasound was compared with IV-CEUS or IC-CEUS alone (P = 0.194 and 0.307). Conclusions Preoperative evaluation by IV- CEUS combined with IC-CEUS can elaborate the intra-cavitary and extra-cavitary changes of malignant obstructive jaundice. The diagnostic accuracy rate could be effectively improved by IV-CEUS combined with IC-CEUS, which can bring favorable clinical benefit.
RESUMEN
Objective To evaluate the treatment of acute cholecystitis patients through laparoscopic cholecystectomy (LC). Methods 387 cases of acute cholecystitis patients who underwent LC were studied retrospectively . Results Of the 387 cases, there were 359 cases of calculus incarcerated cholecystitis , 152 cases of cholecystitis with acute inflammatory symptoms for 72 h or more, 10 cases were converted to Laparotomy (2.6%).The operations lasted for 30~200 min(63.09 ±26.62 min on average),with blood loss about 10~500 mL(51.41 ±32.41 mL on average),and drainage was adopted in 183 cases.No complications developed fol-lowing the surgeries in 3 to 24 months, indicating a 100% cure rate. Conclusion If with good command of rules and techniques during LC operations , It is both safe and feasible to treat acute cholecystitis patients through LC operations .
RESUMEN
AIM:To set up a determination of tanshinone Ⅱ_A and cryptotanshinone in Compound Danshen Tablet(Radix Salviae Miltiorrhizae, Radix Notoginseng, Borneolum Syntheticum) by RP-HPLC. METHODS:Two components could be separated through YWG-C_~18 column with methanol-water (75∶25 by volume) as a mobile phase. The flow rate was 1.0 mL?min~-1 , and the detection wavelength was at 270 nm. RESULTS: The linear range of tanshinone Ⅱ_A and cryptotanshinone were 2.5-50.0 ?g?mL~-1 and 0.625-12.5 ?g?mL~-1 , respectively. The average recovery was 99.76% with RSD 0.92% for tanshinone Ⅱ_A and 98.34% with RSD 0.71% for cryptotanshinone, respectively. CONCLUSION: The method is simple, accurate and rapid with good reproducibility. It can be used for the quality control of Compound Danshen Tablet.
RESUMEN
AIM: To set up identification of Flos Lonicerae and determination of chlorogenic acid in Yingqiao jiedu Pills (Flos Lonicerae, Fructus Forsythiae, Radix Glycyrrhizae, Herba Menthae, etc.) by HPLC. METHODS: A YWG C 18 column was used with the mobile phase consisted of CH 3OH 10%Na 2HPO 4 (adjusting pH to 2.7 with HAc) as gradient elution. The flow rate was 1.0mL?min -1 , and the detection wavelength was at 326nm. RESULTS: Flos Lonicerae in Yinqiaojiedu Pills was identified by HPLC UV. The linear range of chlorogenic acid was 5.0～60?g?mL -1 ( r =0.9999). The average recovery was 98.71% with RSD of 1.55% ( n =5). CONCLUSION: The method is simple, accurate and rapid with good reproducibility. It can be used for the quality control of Flos Lonicerae in Yinqiaojiedu Pills.
