Objective:To observe the effect of electroacupuncture at the Shuigou point on systolic phenotype-related factors and on the JAK1/STAT3 signaling pathway of the middle cerebral artery smooth muscle cells in rats modeling cerebral infarction; and to explore the molecular mechanism of treating cerebral infarction with electroacupuncture.Methods:A total of 108 healthy male Wistar rats were randomly divided into a blank group ( n=6), a sham operation group ( n=6), a model group ( n=48) and an electroacupuncture group ( n=48). The model and electroacupuncture groups were randomly divided into eight phase subgroups at 1h, 3h, 6h, 12h, 24h, 72h, 7d and 14d after the modeling of middle cerebral artery occlusion (MCAO), with six rats in each group. The electroacupuncture groups received electric acupuncture at the Shuigou acupoint for 20min after successful modeling. Neurological Severity scoring (NSS) was used to evaluate the neurological impairment. PLN protein expression in the middle cerebral artery and the expression of JAK1 and STAT3 proteins in the rats′ brain tissue were detected using western blotting. PDGF-AA content in the middle cerebral artery was measured using enzyme-linked immunosorbent assays. Results:Compared with the blank and sham operation groups, the average NSS score and PDGF-AA protein expression had increased significantly in the model and electroacupuncture groups. PLN protein expression had decreased significantly at 12h-14d in the model group, but decreased significantly at 12h-7d in the electroacupuncture group. Compared with those two groups, there was a significant increase in JAK1 protein expression at 1h-72h, 3h-6h, 24h-72h, and14d in the model group. In the electroacupuncture group the corresponding significant increases were over 1h-14d, 1h-6h, 24h, 72h, and 14d. STAT3 protein expression had increased significantly in the model group over 6h-14d and 3h-14d. In the electroacupuncture group those increases were over 6h-14d. Compared to the model group, a significant increase was observed in the expression of PLN protein at 14d, with a significant decrease in NSS at 72h, 7d and 14d. PDGF-AA protein had increased significantly at 6h-7d. For JAK1 protein that was at 12h and 14d, and for STAT3 protein it was over 12h-72h and at 14d.Conclusion:Electroacupuncture at the Shuigou point may regulate the expression of PDGF-AA and the JAK/STAT signaling pathway so as to regulate the normal expression of PLN, and thus smooth muscle contraction to maintain the normal functioning of the middle cerebral artery. This may be one of the molecular mechanisms by which electroacupuncture at the Shuohui point improves nerve functioning in treating cerebral infarction.

BACKGROUND:Patients with lumbar disc herniation have different physical deformities due to nucleus pulposus compression and mechanical imbalance. On this basis,Professor Feng Tianyou proposed the "four-step waist type." Professor Feng Wei proposed the objective quantification of three-dimensional scoliosis angle "four-step waist type."OBJECTIVE:To explore the application value of three-dimensional scoliosis angle in evaluating the efficacy of Feng's spinal manipulation in the treatment of patients with lumbar disc herniation.METHODS:A total of 149 hospitalized patients with lumbar disc herniation were enrolled sequentially,including 96 cases of type-Ⅰ/Ⅱ and 55 cases of type-Ⅲ/Ⅳ. The patients were treated with manual therapy for 2 weeks,and 10 healthy volunteers were included as healthy controls. The three-dimensional scoliosis angle was measured using surface topography technology. The difference of three scoliosis angles between patients with type-Ⅰ/Ⅱ and type-Ⅲ/Ⅳ was compared before and after treatment. The difference between patients after treatment and healthy subjects was compered. The difference of three-dimensional scoliosis angles between type-Ⅰ/Ⅱ and type-Ⅲ/Ⅳ after treatment was compared. The intrinsic correlation of each projection plane of three-dimensional scoliosis angle and its correlation with commonly used clinical efficacy scores were explored.RESULTS AND CONCLUSION:(1) The three-dimensional scoliosis angle was significantly different in patients with type-Ⅰ/Ⅱ and type-Ⅲ/Ⅳ before and after treatment (P<0.05). (2) There were significant differences in coronal curve angle and transverse curve angle between patients with type-Ⅰ/Ⅱ,type-Ⅲ/Ⅳ and healthy subjects (P<0.05),but there was no significant difference in sagittal curve angle (P>0.05). (3) There was a correlation between the angles of each section of the three-dimensional angle,and there was a correlation between the three-dimensional angle and the subjective scale. (4) It is indicated that the three-dimensional scoliosis angle can quantitatively evaluate the changes of body deformity before and after treatment. Quantitative indicators can reveal the changes in the patient's condition before and after treatment. The three-dimensional scoliosis angle can reflect the severity of the impact on the patient's living conditions,but the evaluation of scoliosis by a single plane parameter has certain limitations.

Tripterygium glycosides tablet(TGT),the classical commercial drug of Tripterygium wilfordii Hook.F.has been effectively used in the treatment of rheumatoid arthritis,nephrotic syndrome,leprosy,Behcet's syndrome,leprosy reaction and autoimmune hepatitis.However,due to its narrow and limited treatment window,TGT-induced organ toxicity(among which liver injury accounts for about 40％of clinical reports)has gained increasing attention.The present study aimed to clarify the cellular and molecular events underlying TGT-induced acute liver injury using single-cell RNA sequencing(scRNA-seq)technology.The TGT-induced acute liver injury mouse model was constructed through short-term TGT exposure and further verified by hematoxylin-eosin staining and liver function-related serum indicators,including alanine aminotransferase,aspartate aminotransferase,alkaline phosphatase and total bilirubin.Using the mouse model,we identified 15 specific subtypes of cells in the liver tissue,including endothelial cells,hepatocytes,cholangiocytes,and hepatic stellate cells.Further analysis indicated that TGT caused a significant inflammatory response in liver endothelial cells at different spatial locations;led to marked inflammatory response,apoptosis and fatty acid metabolism dysfunction in hepatocytes;activated he-patic stellate cells;brought about the activation,inflammation,and phagocytosis of liver capsular macrophages cells;resulted in immune dysfunction of liver lymphocytes;disturbed the intercellular crosstalk in liver microenvironment by regulating various signaling pathways.Thus,these findings elaborate the mechanism underlying TGT-induced acute liver injury,provide new insights into the safe and rational applications in the clinic,and complement the identification of new biomarkers and ther-apeutic targets for liver protection.

As a newly epidemic, 2019 coronavirus disease (COVID-19) with a concentrated outbreak poses a great challenge to medical treatment. The severe and critical patients are complex complicatied with the psychological problems, and the medical staff are overworked and under tremendous psychological pressure. The surgeon participated in emergency medical rescue could provide professional treatment for the patients combined with surgical diseases, as well as specialized training for the non-surgeon crew, to reduce surgical-related mortality. With the advantages of good team consciousness, strong aseptic concept and good psychological quality, the surgeons can quickly adapt to and carry out rescue work under the premise of good self-protection. Surgeons need to develop critical care management concepts and focus on the critical care support equipment. Some suggestions are put forward for the standardized training of resident surgeons to cultivate compound talents. It is hoped that this article can lead to the thinking of how to participate in the emergency medical rescue of infectious diseases among surgeons and provide some enlightenment for future surgical education.
