Acupuncture and Tuina are the main non-drug therapies for low back pain, which are recommended by the guidelines. Acupuncture and Tuina can alleviate pain, which is regarded as conditional specific outcome, and improve mental, emotional problems, as non-conditional specific outcomes. There are some problems of the outcome assessment of acupuncture and Tuina treatment for pain such as insufficient evaluation of specific effect and unclear evaluation of characteristic outcome. Therefore, the key to above problems is to construct a Specific ouTcomE Assessment Modal of acupuncture and Tuina treatment for pain (STEAM-A&T) based on the qualitive and quantitative methods. By describing the experience, narrative expression, feelings and needs of patients who receiving acupuncture and Tuina treatment, the item banks of acupuncture and Tuina treatment effect are constructed, and the characteristic outcome of acupuncture and Tuina for pain will be screened, and then the relationship model among outcomes is constructed and optimized, which reflected the characteristics of acupuncture and Tuina for pain from multiple dimensions, multiple levels and multiple views. We reveal the relationship between the outcome of acupuncture and Tuina for pain. It will provide a new theory and methods for the construction of specific outcome assessment modal of Traditional Chinese Medicine.

The discovery of regulatory cell death has led to new breakthroughs in the field of disease treatment. As a novel discovered regulatory cell death in the past decade, ferroptosis is characterized by abnormal increase of intracellular iron ions and peroxidative damage of cell membrane lipids, morphological features of mitochondrial volume reduction, increased mitochondrial membrane density, as well as mitochondria decrease or disappear. The mechanism of ferroptosis is mainly associated with factors such as iron metabolism disorder, lipid metabolism abnormality, amino acid antioxidant system imbalance and oxidative stress. Since the liver is the main organ of human body for storing iron ions, it is necessary to deeply investigate the mechanism of ferroptosis in liver diseases. Relevant studies have shown that ferroptosis plays different roles in various liver diseases and is closely related to the process of liver diseases, including drug-induced liver injury, alcoholic fatty liver disease, non-alcoholic fatty liver diseases, viral hepatitis, liver fibrosis and hepatocellular carcinoma. The aim of this review is to link ferroptosis and liver diseases, concentrating on the iron metabolism disorder, accumulation of lipid peroxides in cell membranes, imbalance of amino acid antioxidant system, hyperpolarization of mitochondrial membrane potential and its accumulation of lipid peroxides, oxidative stress-related transcription factors and other aspects. This review summarizes the regulatory mechanism, current situation and the roles of ferroptosis in liver diseases, in order to provide a new theoretical basis and ideas for the in-depth study of ferroptosis and the treatment of liver diseases.

UPLC-Q-TOF-MS combined with network pharmacology and experimental verification was used to explore the mechanism of acupoint sticking therapy(AST) in the intervention of bronchial asthma(BA). The chemical components of Sinapis Semen, Cory-dalis Rhizoma, Kansui Radix, Asari Radix et Rhizoma, and Zingiberis Rhizoma Recens were retrieved from TCMSP as self-built database. The active components in AST drugs were analyzed by UPLC-Q-TOF-MS, and the targets were screened out in TCMSP and Swiss-TargetPrediction. Targets of BA were collected from GeneCards, and the intersection of active components and targets was obtained by Venny 2.1.0. The potential targets were imported into STRING and DAVID for PPI, GO, and KEGG analyses. The asthma model induced by house dust mite(HDM) was established in mice. The mechanism of AST on asthmatic mice was explored by pulmonary function, Western blot, and flow cytometry. The results indicated that 54 active components were obtained by UPLC-Q-TOF-MS and 162 potential targets were obtained from the intersection. The first 53 targets were selected as key targets. PPI, GO, and KEGG analyses showed that AST presumedly acted on SRC, PIK3 CA, and other targets through active components such as sinoacutine, sinapic acid, dihydrocapsaicin, and 6-gingerol and regulated PI3 K-AKT, ErbB, chemokine, sphingolipid, and other signaling pathways to intervene in the pathological mechanism of BA. AST can improve lung function, down-regulate the expression of PI3 K and p-AKT proteins in lung tissues, enhance the expression of PETN protein, and reduce the level of type Ⅱ innate immune cells(ILC2 s) in lung tissues of asthmatic mice. In conclusion, AST may inhibit ILC2 s by down-regulating the PI3 K-AKT pathway to relieve asthmatic airway inflammation and reduce airway hyperresponsiveness.

Objective:To explore the effect of short-term training on pressure injury prevention cognition and nursing behavior of nurses in Operating Room.Methods:From July 2018 to September 2019, 36 nurses working in the Operating Room of the Affiliated Hospital of Hangzhou Normal University were selected as the research object by convenience sampling. The questionnaire was used to find out how they acquired knowledge about pressure injury before training. Then, the short-term training in pressure injury prevention lasting for 3 months was conducted. The nurses' mastery of knowledge and nursing skills on pressure injury prevention before and after training were compared. Using the convenience sampling method, 80 surgical patients who received treatment in the hospital from July to December 2018 were selected as the control group (before training) , and 80 surgical patients from April to September 2019 were selected as the observation group (after training) . The incidence of surgery-related pressure injury was compared between the two groups.Results:Before the training, the number of nurses who acquired knowledge about pressure injury through in-hospital learning accounted for 80.56% (29/36) , followed by the Internet, related books and nursing journals, accounting for 52.78% (19/36) and 44.44% (16 /36) and 44.44% (16/36) respectively. After short-term training, 36 nurses' mastery of pressure injury-related knowledge, pressure injury nursing behavior scores and total scores were higher than those before training, and the differences were statistically significant ( P<0.01) . The incidence of pressure injury in the observation group was lower than that in the control group, and the difference was statistically significant ( P<0.05) . Conclusions:Short-term training for nurses in Operating Room can effectively improve their awareness of pressure injury and nursing behavior, and reduce the incidence of pressure injury in surgical patients.

OBJECTIVE: To summarize the experience in the application of muscle relaxants in the perioperative period in neonates with congenital esophageal atresia-tracheoesophageal fistula (EA-TEF). METHODS: A retrospective analysis was performed on the medical data of 58 previously untreated neonates with EA-TEF who were treated in the Neonatal Center of Beijing Children's Hospital, Capital Medical University from 2017 to 2019. The incidence rate of anastomotic leak was compared between the neonates receiving muscle relaxants for different durations after surgery (≤ 5 days and > 5 days). The correlation between the duration of postoperative use of muscle relaxants and the duration of mechanical ventilation was evaluated. RESULTS: Among the 58 neonates with EA-TEF, 44 underwent surgery, among whom 35 with type III EA-TEF underwent thoracoscopic surgery. Among these 35 neonates, 30 (86%) received muscle relaxants after surgery, with a median duration of 4.75 days, and 6 (18%) experienced anastomotic leak. There was no significant difference in the incidence rate of anastomosis leak between the ≤ 5 days and > 5 days groups ( CONCLUSIONS Prolonged use of muscle relaxants after surgery cannot significantly reduce the incidence of anastomotic leak, but can prolong the duration of invasive mechanical ventilation in neonates with EA-TEF. Therefore, prolonged use of muscle relaxants is not recommended after surgery.

Irreducible dislocation of the elbow is an uncommon event. We present the case of a posterolateral elbow dislocation after a fall injury in a 67-year-old woman. A closed reduction performed in the emergency department was unsuccessful since the limited passive range of motion resulted in difficulty to perform longitudinal traction and flexion. Computed tomography images showed that the posterolateral aspect of the capitellum was impacted by the tip of the coronoid process, thus appearing similar to the Hill-Sachs lesion in the humeral head. Subsequent open reduction of the elbow revealed the dislocation to be irreducible since the tip of the coronoid process had wedged into a triangular Hill-Sachs-like lesion in the capitellum. The joint was reduced by providing distal traction on the forearm, and main fragments were disengaged using digital pressure. At the 3-month follow-up, the patient reported no dislocations, and had an acceptable range of motion. Thus, we propose that to avoid iatrogenic injury to the joint or other nearby structures, irreducible dislocations should not be subjected to repeated manipulation.
