A multiple closed-loops robotic calibration for accurate surgical puncture.

Background: Robotic puncture system increasingly demands stringent standard in target location accuracy. The positional and orientational transformation relationships among all components of the system are supposed to be calibrated and identified preoperatively.

Aims: The target location performance is directly determined by the calibration result.

Therapeutic targets for the anemia of predialysis chronic kidney disease: a meta-analysis of randomized, controlled trials.

Anemia is one of the major complications in predialysis patients with chronic kidney disease (CKD). A clearer cognition of the prognostic impact of hemoglobin (Hb) or hematocrit (Hct) target on the outcomes of predialysis patients with CKD is significant. This article aims to establish the suitable hemoglobin target to provide clinical guidance.

Hemoglobin targets for the anemia in patients with dialysis-dependent chronic kidney disease: a meta-analysis of randomized, controlled trials.

Background: Anemia is extremely common among dialysis patients and underlies some of the symptoms associated with reduced kidney function, including fatigue, depression, reduced exercise tolerance, and dyspnea.

Objectives: A clearer cognition of the prognosistic impact of hemoglobin (Hb) or hematocrit (Hct) target for the outcomes of dialysis patients is urgent. This article aims to establish the suitable hemoglobin in order to provide clinical guidance.

[Automatic Robotic Puncture System for Accurate Liver Cancer Ablation Based on Optical Surgical Navigation].

This paper designed an automatic robotic puncture system for accurate liver cancer ablation based on optical surgical navigation. The near-infrared optical surgical navigation system we constructed for liver ablation was applied to carry out surgical planning and simulation, the near-infrared cameras dynamically tracked the current position of puncture needle relative to the location of the patient's anatomy, then guided the surgery robot to position precisely in three-dimensional space and performed the surgery.
