OBJECTIVE To investigate the effects and potential mechanism of persimmon leaf (PL) extract against ferroptosis induced by H2O2 in IEC-6 cells. METHODS Using IEC-6 cells as object, the effects of ferroptosis inhibitor ferrostatin-1 on IEC-6 cell viability induced by H2O2 were investigated; IEC-6 cells were divided into control group, H2O2 group, H2O2+PL 25 μg/mL group and H2O2+PL 50 μg/mL group. The levels of oxidant stress indexes [content of malondialdehyde (MDA), activity of superoxide dismutase (SOD), and levels of reactive oxygen species (ROS)], mitochondrial membrane potential (MMP) as well as mRNA and protein expressions of nuclear factor-erythroid-2 related factor 2 (Nrf2), heme oxygenase-1 (HO-1), NADPH/quinone oxidoreductase-1 (NQO-1), cystine/glutamate anti-porter (xCT), glutathione peroxidase 4 (GPX4) and ferritin heavy chain (FTH) were detected. RESULTS Ferroptosis inhibitor ferrostatin-1 could significantly increase the survival rate of H2O2-induced cells (P< 0.01). Compared with the control group, MDA content, ROS level, mRNA expressions of Nrf2 and NQO-1 as well as protein expressions of Nrf2 and HO-1 were increased or up-regulated significantly, while SOD activity, MMP, mRNA expressions of xCT, GPX4 and FTH as well as protein expressions of GPX4 and FTH were decreased or down-regulated significantly (P<0.01 or P<0.05). Compared with the H2O2 group, oxidative stress Δ indexes of H2O2+PL 25, 50 μg/mL groups were reversed to different extents, MMP level was increased significantly, as well as mRNA and protein expressions of Nrf2, HO-1, NQO-1,xCT, GPX4 and FTH were up-regulated to different extents;there were statistical significances in some indexes between groups (P<0.01 or P<0.05). CONCLUSIONS PL extract can alleviate mitochondrial membrane damage and abnormal accumulation of ROS caused by H2O2, which may be related to the inhibition of ferroptosis by activating the Nrf2/HO-1 signaling pathway.

OBJECTIVE To study the mechanism of Xinnao shutong capsule alleviating cerebral ischemia reperfusion injury (CIRI) in rats by regulating the ferroptosis pathway. METHODS SD rats were randomly divided into sham operation group, model group, Xinnao shutong low-dose, high-dose group (220, 440 mg/kg), Ginkgo biloba leaves extract group (positive control, 150 mg/kg). Each group of rats was orally administered with the corresponding medication/normal saline for 7 consecutive days. Transient occlusion of the middle cerebral artery was adopted to induce the CIRI model; the samples were taken 24 h after the operation; the cerebral infarction area of rats was detected, and the cerebral infarction rate was calculated. The pathological changes of brain tissues were observed, and the levels of lipid peroxide (LPO), malondialdehyde (MDA) and glutathione (GSH) in cerebral tissue were detected; mRNA and protein expressions of nuclear factor-erythroid 2-related factor 2 (Nrf2), heme oxygenase 1(HO-1) and glutathione peroxidase 4 (GPX4) were all detected in cerebral tissue of rats. RESULTS Compared with model group, the cerebral infarction rate, the content of total iron in cerebral tissue and serum level of LPO (except for Ginkgo biloba leaves extract group and Xinnao shutong low-dose group) were all decreased significantly in G. biloba leaves extract group and Xinnao shutong groups (P<0.05 or P<0.01); the serum level of GSH, the protein and mRNA expressions of Nrf2, HO-1 and GPX4 were all increased significantly (P<0.05 or P<0.01). The pathological damage to brain tissue was reduced, the number of nerve cells increased, the edema was alleviated, and the nuclear membrane was flattened. CONCLUSIONS Xinnao shutong capsule can inhibit ferroptosis and reduce CIRI, the mechanism of which may be associated with the activation of the Nrf2/HO-1/GPX4 signaling pathway.

OBJECTIVE:
To investigate the effect of hyperbaric oxygen (HBO) on paroxysmal sympathetic hyperexcitation (PSH) after brain injury.
METHODS:
A multicenter retrospective study was conducted. Fifty-six patients with PSH who received HBO treatment from four hospitals in Henan Province from January 2021 to September 2023 were selected as the HBO group, and 36 patients with PSH who did not receive HBO treatment from Zhengzhou People's Hospital from May 2018 to December 2020 were selected as the control group. PSH assessment measure (PSH-AM) score [clinical feature scale (CFS) score+diagnostic likelihood tool (DLT) score] and Glasgow coma scale (GCS) were compared before and after HBO treatment, and between HBO group and control group to evaluate the effect of HBO treatment on prognosis of PSH patients.
RESULTS:
There were no statistically significant differences in age, gender, PSH etiology, GCS score, time from onset to occurrence of PSH, CFS score, CFS+DLT score and frequency of PSH episodes between the two groups, indicating comparability. The duration of HBO treatment ranged from 3 to 11 days for 56 patients receiving HBO treatment, and the duration of HBO treatment ranged from 3 to 5 courses. Compared with before treatment, after HBO treatment, PSH symptoms in HBO patients were significantly relieved (body temperature increase: 14.29% vs. 64.29%, heart rate increase: 25.00% vs. 98.21%, shortness of breath: 14.29% vs. 76.79%, blood pressure increase: 8.93% vs. 85.71%, sweating: 10.71% vs. 85.71%, muscle tone increased: 19.64% vs. 75.00%, all P < 0.05), CFS+DLT score decreased significantly (16.90±4.81 vs. 22.12±3.12, P < 0.01), GCS score improved (12.31±5.34 vs. 5.95±2.18, P < 0.01). After 30 days of hospitalization, compared with the control group, PSH symptoms in the HBO group were improved (body temperature increase: 14.29% vs. 19.44%, heart rate increase: 19.64% vs. 25.00%, shortness of breath: 10.71% vs. 27.78%, blood pressure increase: 7.14% vs. 22.22%, sweating: 8.93% vs. 25.00%, muscle tone increased: 19.64% vs. 38.89%, all P < 0.05 except body temperature increase), CFS+DLT score decreased (16.90±3.81 vs. 19.98±4.89, P < 0.05), GCS score increased (14.12±4.12 vs. 12.31±4.14, P < 0.01), the length of intensive care unit (ICU) stay was shortened (days: 18.01±5.67 vs. 24.93±8.33, P < 0.01).
CONCLUSIONS
HBO treatment can significantly relieve the symptoms of patients with PSH after brain injury and provide a new idea for the treatment of PSH patients.

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.

Tuina (Chinese massage) is an important part of Traditional Chinese Medicine. It is a simple and inexpensive technique, and has shown effectiveness for muscle and bone diseases, visceral diseases, gynecological diseases, and common diseases in children. This paper aims to analyze the factors influencing the effects of Tuina. The factors included the aspects of diagnosis, treatment, prognosis, patient factors and doctor-patient communication. During the treatment of Tuina, doctors should carry out good doctor-patient communication, properly evaluate and exam patients, and clarify diagnosis, take appropriate Tuina techniques according to the patients' constitution, health condition, and comorbidity. Only in such way, could Tuina achieve effectiveness and safety.

Objective:To summarize the characteristics of the participants (P), interventions (I), control measures (C), outcomes (O) and study design (S) of the clinical study of chronic back pain (CBP) in recent years; To further systematically organize the outcomes of the clinical study of CBP and their corresponding measurement tools.Methods:Clinical studies of CBP were retrieved from various databases including CNKI, Wanfang Database, VIP, SinoMed, Cochrane Library, Pubmed, Embase, Web of Science, etc. The search period was from January 1, 2015 to December 31, 2019. The retrieved literature was extracted and analyzed.The retrieved literatures will be extracted and analyzed. The retrieved literature was subjected to data extraction and analysis, and the quality of outcome indicators was evaluated according to 6 items. The Newcastle-Ottawa Scale ( NOS ) was used to evaluate the quality of cohort studies and case-control studies. Analyze the relationship between outcome indicators and interventions.Results:A total of 3 028 articles were finally included after examination and screening. The top 7 diagnoses of CBP were low back pain, lumbar disc protrusion, lumbar vertebral stenosis, lumbar vertebral slip, lumbar disc degression, non-specific chronic low back pain and post-operative pain syndrome. The top 7 intervention measures in clinical studies of CBP were surgery, acupuncture, physiotherapy, Tuina, exercise therapy, Western medicine painkillers and oral Chinese patent medicines. A total of 47 outcomes and 348 outcome measurement tools were reported in the literature included.Conclusion:In the clinical study of CBP in the recent years, there are problems such as incomplete and low quality of reporting, a wide variety of outcome measurement tools and lack of uniform reporting standards. The characteristics of patients determine the common characteristics of outcomes selection and it is also necessary to consider the specific outcomes related to interventions.

Pediatric Tuina is an important part of traditional Chinese medicine, but the operation technical standard is less developed. It is favored by TCM practitioners in China and abroad, due to its simple operation and clinical effects. The specific acupoint of pediatric tuina is the core of its therapy, but due to the numerous schools of pediatric tuina in China, the consensus of location and operation on some specific acupoints have not been reached. To meet the clinical practice needs of pediatric tuina practitioners and follow the evidence-based principles, we determined to develop International Pediatric Tuina Specific Acupoints and Operation Technical standaeds, considering the diversity of pediatric tuina schools. We hope to lay a foundation for evidence-based practice, trials design and guidelines development of pediatric tuina.
