Microscopic Interface and Multiscale Failure Analysis of Proposed Molecular Chain Polymers Based on Aifantis Strain Gradient Theory.

A study on the microscopic morphology of real-world polymer blends and its mechanism of change showed that the microscopic morphology of equiproportional mixtures gradually changed from a dense body structure to a network structure with the addition of the total polymer concentration up to 20%; the microscopic morphology of mixtures with different proportions was characterized by the most uniform network structure of equiproportional mixtures when the total polymer concentration was 20%. The polymer acts as a defoamer in the mixed system. In this paper, the relationship between the microscopic morphology of each mixture and the physicochemical behavior of the two polymer chains in the mixed system was investigated on the basis of the Aifantis strain gradient theory.

[Medicated plaster at Dazhui (GV 14) for preventing perioperative hypothermia in patients undergoing PKRP and ureteroscopic laser lithotripsy].

Objective: To observe the preventive effect of medicated plaster at Dazhui (GV 14) on preventing perioperative hypothermia in patients undergoing plasmakinetic resection of prostate (PKRP) and ureteroscopic laser lithotripsy.

Methods: A total of 300 patients with ASA gradeⅠorⅡreceiving ureteroscopic laser lithotripsy or PKRP under total intravenous anesthesia (TIVA) were randomly divided into an observation group and a control group, 150 cases in each group. The patients in the control group received routine heat preservation measures, while on the basis of the control group, the patients in the observation group were treated with medicated plaster at Dazhui (GV 14) 30 min before operation.

[Efficacy on analgesia with electric stimulation of long-term retaining needle after laparoscopic cholecystectomy].

Objective: To observe the clinical effect of electric stimulation of long-term retaining needle on analgesia after laparoscopic cholecystectomy (LC) and the impacts on the post-surgical flatus time.

Methods: Under static absorptive composite general anesthesia, 90 cases of LC were randomized into three groups, 30 cases in each one. In the control group, the analgesia was not applied after LC.
