Objective To investigate the feasibility of amplitude of intraoperative nerve action potentials (NAP) for early quantitative diagnosis of peripheral nerve injury. Methods The sciatic nerve injury model were established in 16 rabbits. Intraoperative NAP were recorded after 4 weeks. According to amplitude of NAP, the injuried nerve were divided into 3 groups: NAP < 100 μV in A group, 100 μV ≤NAP < 500 μV in B group, NAP ≥ 500 μV in C group. Nerve specimen 1cm distal to injuried point were resected that received glycine silver stain and image analysis including number, diameter and cross section area of regenerative axons. Footprint parameter and ulcer area were measured and contrasted between each two groups. Results The number, diameter and cross section area of A group regenerative axons have significant difference with B and C group, no significant difference between B and C group; Footprint parameter and ulcer area have significant difference in each two groups. Conclusion Amplitude of intraoperative NAP can be a quantitative criteria to diagnose the degree of peripheral nerve injury that provides experiment evidence for guide intraoperative decision-making in clinical practice.

Primary liver cancer has various potential causes and insidious onset, and its progression is affected by many factors. Immunotherapy and targeted drug therapy have been used as non-radical treatment methods for primary liver cancer, but they cannot achieve a satisfactory effect and may lead to drug resistance. In recent years, the wide application of 16s high-throughput sequencing and the in-depth studies of microbiology have revealed the key role of microorganisms in the development and progression of liver cancer. The association of the liver with oral and intestinal flora is gradually clarified, and the regulation of oral and intestinal flora has brought new treatment methods for the disease. This article reviews the microbial theory of the oral-gut-liver axis and its application and development in the treatment of primary liver cancer.

ObjectiveTo investigate the effectiveness and safety of Bushen Yugu Formula (补肾愈骨方) promoting postoperative functional rehabilitation of patients with chronic lateral ankle instability (CLAI) with syndrome of liver-kidney insufficiency and sinews-vessels deprived of nourishment. MethodsClinical data were retrospectively collected from 40 patients with CLAI with syndrome of liver-kidney insufficiency and sinews-vessels deprived of nou-rishment who underwent external ankle ligament repair surgery. They were divided into 20 cases each in the treatment group and control group according to whether or not they took Bushen Yugu Formula; patients in the control group underwent postoperative functional rehabilitation, while patients in the treatment group took Bushen Yugu Formula in the 3rd and 4th postoperative weeks combined with the rehabilitation. The American Orthopaedic Foot and Ankle Society (AOFAS) scores, the flexion/extension and internal/external rotation, the imaging scores of the ankle joint on the operated side and the traditional Chinese medicine (TCM) syndrome scores were recorded in the preoperative and 3-month postoperative, respectively. The patients' liver and kidney functions were tested in the preoperative and 4-month postoperative, and adverse events during treatment were recorded. ResultsCompared with the preoperative period, the AOFAS scores were higher and the TCM syndrome scores were lower in both groups 3 months after surgery (P<0.01), and the ankle internal and external rotation mobility and imaging scores were higher in the treatment group (P<0.05 or P<0.01), and ankle flexion/extension mobility was lower in the control group (P<0.05). At 3 months after surgery, the AOFAS score was higher in the treatment group than in the control group, and the TCM syndrome score was lower than in the control group (P<0.05 or P<0.01). Two cases of gastrointestinal reactions were reported in the treatment group, which relieved on their own after stopping the formula, and no abnormality was observed in liver and kidney function indexes. ConclusionBushen Yugu Formula can promote functional rehabilitation of ankle joint and improve clinical symptoms in CLAI patients with syndrome of liver-kidney insufficiency and sinews-vessels deprived of nourishment, and it shows a good safety.
