Abstract

Laparoscopic lateral pelvic lymph node dissection (LPND) is limited by complex neurovascular bundles in the narrow pelvic sidewall and various post-operative complications. Indocyanine green (ICG) has been applied to increase the number of harvested lymph nodes and reduce the injury of irrelevant vessels in patients with rectal cancer. However, few studies on the recurrence rate of ICG fluorescence imaging-guided laparoscopic LPND were reported. This retrospective study enrolled 50 middle- low rectal cancer patients who were treated by LPND. After propensity score matching, 20 patients were matched in each of the indocyanine green (ICG) guided imaging group (ICG group) and non-ICG guided imaging group (non-ICG group). The average follow-up time was 13.5 months (12–15 months). Our results showed that the total number of harvested lymph nodes in the ICG group was significantly higher than that in the non-ICG group (P < 0.05), and intraoperative blood loss and post-operative hospital stay times in the ICG group were less than those in the non-ICG group (P < 0.05). After 12 months of follow-up, no residual lymph node and local tumor recurrence were found for patients in the ICG group. Four patients in the non-ICG group detected residual lymph nodes at the 3-month visit. Our findings highlighted the importance of ICG fluorescence-guided imaging in LPND because it has unique advantages in improving the number of lymph node dissections, surgical accuracy, and decreasing the residual lymph nodes and local tumor recurrence. In addition, ICG fluorescence guidance technology can effectively shorten the operation time, and it is simple to operate, which is worth popularizing.

3. [Spatial Temporal Characteristics and Cluster Analysis of Chemical Components for Ambient PM

Author

Hui-Tao, Zhang, Ying-Ze, Tian, Bao-Shuang, Liu, Jia-Mei, Yang, Jia, Yu, Pan, Gong, Jian-Hui, Wu, and Yu-Fen, Zhang

Abstract

The characteristics of chemical components of particulate matter are good indicators for analyzing sources and causes of pollution. The spatial and temporal distribution characteristics of particulate matter can reflect regional pollution problems in urban development, providing a basic dataset to support effective control of particulate matter sources. We collected PM

Abstract

A set of on-line test equipment for drilling fluid rheological parameters is developed, which can realize real-time on-line monitoring. Design method: first of all let the drilling fluid to flow through the same shape and dimension of the section, in turn, change, will produce different velocity of different section, between all the pipe sections using pressure sensor real-time acquisition of differential pressure value, and the differential pressure and flow rate signals to the data acquisition system for transformation, such as display and processing, and then according to the rheology model to calculate the rheological parameters of drilling fluid to be measured. The final measurement results will be compared with the results of rotary viscometer measurement, shows the practicability and feasibility of the device have zero since the calibration function, measuring range is 5-150 mpa’s, measurement accuracy can satisfy the requirement of 5%.

Abstract

A straight pipe viscometer is proposed, which consists of the measuring sub-system and the data-acquisition and signal processing sub-system. The measuring sub-system include straight pipe, pressure transmitter, Coriolis flow-meter and slurry bump, and the data-acquisition and signal processing sub-system include single-chip processor, A/D converter, digital display, serial output port, drive circuit and so on. The measuring principle and working process of the straight pipe viscometer are analyzed. The measurement data and results are given and compared with test results of rotary viscometer in the same test conditions. The measuring accuracy is 3% at 5-150mPas, and the online measurement of viscosity is implemented.
