Objective To evaluate the value of ultrasonography scoring system in differential diagnosis of well-differentiated liposarcomas (WDLPS) and benign lipoma (LP), and to provide evidence for the differential diagnosis and treatment choice. Methods Fourteen WDLPS cases (total of 15 masses) and 37 LP cases (total of 40 masses) were diagnosed by surgical histopathology, which clinical data and the ultrasound images were analyzed retrospectively. The parameters including age, gender, region, mass length, length/width ratio, shape, margin, envelope echoes, echogenicity, texture, location, blood flow were compared between the groups above. A scoring system was established by analyzing the parameters with statistical differences, and the ROC curve was plotted to calculate the best cut-off value and evaluate the diagnostic efficiency of the scoring system. Results There were statistically significant differences between two groups in the following six parameters: age, mass length, length/width ratio, envelope echoes, location, blood flow(P＜0.05). The scoring system was established by assigning 0 or 1 point to each factor, and the total score was 0～6 points. The highest diagnostic efficiency of WDLPS was observed at the cut-off value ≥ 3. The sensitivity, specificity, accuracy, the positive predictive value and the negative predictive value was 86.7%, 77.5%, 80%, 59.1%, 93.9% respectively. Conclusions The ultrasonography-based scoring system has a better diagnostic efficacy in differentiating WDLPS and LP, which can provide an important reference basis for the selection of clinical treatment, and is worthy of promotion and application.

Objective To compare the efficacy and safety of remimazolam tosilate and propofol in painless ultrasonic gastroscopy. Methods In a randomized, single-blind controlled study, 60 patients undergoing ultrasonic gastroscopy were selected and divided into observation group (31 cases) and control group (29 cases). Observation group was anesthetized with remimazolam tosilate, while control group was anesthetized with propofol. Two groups' hemodynamic index, perioperative adverse events, changes of MOAA/S score, awakening and departure time were observed at different time points during anesthesia. Results The observation group had less changes on hemodynamics. The observation group had enough depth of sedation, while the control group had a deeper degree of sedation. The onset time of the two groups was similar and both awoke quickly and left, but the awakening time and leaving time in the observation group were slightly shorter. Adverse events in the control group were more than those in the observation group. Conclusions Remimazolam tosilate for painless ultrasonic gastroscopy had little effect on hemodynamics, which can generate enough depth of sedation, and make patients wake up quickly. In addition, the incidence of its adverse events was low, and the overall effectiveness and safety were superior to those of propofol.
