Inflammation is the body’s response to damage， infection or other stimuli， but its excessive or continuous development can lead to a variety of diseases. Although modern medical anti-inflammatory therapies were widely used， it is often accompanied by limitations such as more adverse reactions. Based on the “holistic view” and “differential treatment”， traditional Chinese medicine （TCM） regards inflammation as a manifestation of the imbalance of yin and yang in the body and the conflict between good and evil. The application of anti-inflammatory TCM is not only aimed at the pathological state of “inflammation”， but also based on the overall consideration of “syndrome”. According to different types of syndrome， anti-inflammatory TCM can be divided into heat-clearing and detoxifying agents （such as Lonicera japonica and Isatis indigotica ）， heat-clearing and drying dampness agents （such as Coptidis Rhizoma）， blood-activating and stasis-dissolving agents （such as Salvia miltiorrhiza ） and vital qi-strengthening and pathogenic factor-expelling agents （such as Panax ginseng ）. Four types of anti-inflammatory TCM restore the body’s immune balance through the systematic regulation of multi-component， multi-target and multi-pathway， exhibiting a good anti-inflammatory effect. Future research should focus on integrating systematic biology， applying artificial intelligence， carrying out high-quality evidence-based research， and combining traditional Chinese medicine and Western medicine， so as to reveal the overall regulatory law of anti-inf lammatory effects of TCM and promote clinical rational use.

Objective:To explore the efficacy and safety of vagus nerve stimulation (VNS) combined with rehabilitation training in recovery of upper limb function in patients with ischemic stroke (IS) through Meta-analysis.Methods:Randomized controlled trials on upper limb motor dysfunction in IS patients accepted VNS published in PubMed, Web of Science, Embase, CNKI, Wanfang and VIP databases, and Chinese Biomedical Literature Database were retrieved. The retrieval period was from establishment of the databases to April 2025. Quality of the trials was assessed according to Cochrane handbook for systematic reviews of interventions (version 5.1). Two researchers independently screened the literature, extracted the data and evaluated the risk of bias of the included articles; and then, Meta-analysis was conducted by RevMan 5.4 software.Results:Eleven articles of randomized controlled trails were chosen, including 495 patients. Three articles were rated as A-level in terms of quality, and 8 were rated as B-level. Overall bias risk of the included studies was low. Results of Meta-analysis showed that compared with the control group (rehabilitation training alone), the intervention group (VNS combined with rehabilitation training) had significantly improved upper limb motor function (Fugl-Meyer assessment of upper limb motor function: standardized mean difference [ SMD]=0.77, 95% CI: 0.24-1.30, P<0.001) and activities of daily living (modified Barthel index: SMD=0.86, 95% CI: 0.56-1.16, P<0.001). Meanwhile, compared with those in the control group, incidence of adverse events ( RR=1.12, 95% CI: 0.95-1.33, P=0.170) and incidence of severe adverse events ( RR=1.67, 95% CI: 0.51-5.50, P=0.400) in the intervention group did not significantly increase. Results of subgroup analysis showed that compared with that in the control group, more significantly improved upper limb motor function was noted in patients from the non-invasive VNS intervention sub-group ( SMD=1.09, 95% CI: 0.46-1.72, P<0.001), intervention sub-group with a frequency of 5 times per week ( SMD=1.73, 95% CI: 0.58-2.87, P<0.001), and intervention sub-group with a duration of 4 weeks ( SMD=1.09, 95%CI: 0.72-1.47, P<0.001). Conclusion:VNS combined with rehabilitation training has good safety and efficacy in upper limb motor dysfunction after IS.

Objective:To investigate the therapeutic effect of combined extracranial-intracranial revascularization on elderly patients with symptomatic chronic internal carotid artery occlusion, and to evaluate its safety and efficacy in the elderly population.Methods:A retrospective analysis was conducted on 35 elderly patients(aged ≥60 years)who underwent combined extracranial-intracranial revascularization for symptomatic chronic internal carotid artery occlusion in the Department of Neurosurgery, Renmin Hospital of Wuhan University from January 2017 to June 2022.The clinical data during hospitalization, as well as the follow-up data within 2 years after operation, were collected and analyzed.Results:A total of 35 cases of combined extracranial-intracranial revascularization were performed on 35 patients.The age at surgery ranged from 60 to 74 years(mean age 65.5 ± 4.2 years). The incidence of reversible neurological deficits within 2 weeks postoperation was 34.3%, and the incidence of focal cerebral infarction within 30 days postoperation was 5.7%.The patency rate of the bridging vessel was 97.1% at 3 months postoperation., and the incidence of focal cerebral infarction during the follow-up period of 30 days to 2 years postoperation was 2.9%.At 3 months after surgery, computed tomography perfusion imaging showed that regional cerebral blood flow(rCBF), regional cerebral blood volume(rCBV), regional mean transit time(rMTT), and regional time to peak(rTTP)were improved compared with those before surgery.The modified Rankin scale score decreased compared to preoperative values, while the Montreal Cognitive Assessment showed improvement in cognitive function compared to preoperative levels(all P<0.05). From 6 months to 1-year postoperation, cerebral angiography showed that 38.7% of the patients had neovascularization of Matsushima grade A or grade B. No cases of cerebral hemorrhage or death was observed during the treatment and follow-up. Conclusions:Combined extracranial-intracranial revascularization is safe and effective for elderly patients with symptomatic chronic internal carotid artery occlusion, which can improve the patient′s hemodynamic disorders, prevent infarction events, and improve the patients′ neurological function and cognitive ability.

Background::The combination of high-frequency oscillations (HFOs) with single-mode imaging methods has been proved useful in identifying epileptogenic zones, whereas few studies have examined HFOs combined with multimodal imaging methods. The aim of this study was to evaluate the prognostic value of ripples, an HFO subtype with a frequency of 80 to 200 Hz is combined with multimodal imaging methods in predicting epilepsy surgery outcome.Methods::HFOs were analyzed in 21 consecutive medically refractory epilepsy patients who underwent epilepsy surgery. All patients underwent positron emission tomography (PET) and deep electrode implantation for stereo-electroencephalography (SEEG); 11 patients underwent magnetoencephalography (MEG). Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in predicting surgical outcome were calculated for ripples combined with PET, MEG, both PET and MEG, and PET combined with MEG. Kaplan-Meier survival analyses were conducted in each group to estimate prognostic value.Results::The study included 13 men and 8 women. Accuracy for ripples, PET, and MEG alone in predicting surgical outcome was 42.9%, 42.9%, and 81.8%, respectively. Accuracy for ripples combined with PET and MEG was the highest. Resection of regions identified by ripples, MEG dipoles, and combined PET findings was significantly associated with better surgical outcome (P < 0.05). Conclusions::Intracranial electrodes are essential to detect regions which generate ripples and to remove these areas which indicate good surgical outcome for medically intractable epilepsy. With the assistance of presurgical noninvasive imaging examinations, PET and MEG, for example, the SEEG electrodes would identify epileptogenic regions more effectively.

The emergence of coronavirus disease 2019 (COVID-19) not only poses a serious threat to the health of people worldwide but also affects the global economy. The outbreak of COVID-19 began in December 2019, at the same time as the influenza season. However, as the treatments and prognoses of COVID-19 and influenza are different, it is important to accurately differentiate these two different respiratory tract infections on the basis of their respective early-stage characteristics. We reviewed official documents and news released by the National Health Commission of the People's Republic of China, the Chinese Center for Disease Control and Prevention (China CDC), the United States CDC, and the World Health Organization (WHO), and we also searched the PubMed, Web of Science, Excerpta Medica database (Embase), China National Knowledge Infrastructure (CNKI), Wanfang, preprinted bioRxiv and medRxiv databases for documents and guidelines from earliest available date up until October 3rd, 2020. We obtained the latest information about COVID-19 and influenza and summarized and compared their biological characteristics, epidemiology, clinical manifestations, pathological mechanisms, treatments, and prognostic factors. We show that although COVID-19 and influenza are different in many ways, there are numerous similarities; thus, in addition to using nucleic acid-based polymerase chain reaction (PCR) and antibody-based approaches, clinicians and epidemiologists should distinguish between the two using their respective characteristics in early stages. We should utilize experiences from other epidemics to provide additional guidance for the treatment and prevention of COVID-19.

Objective:To examine the prospective association of pubertal timing and tempo with depressive symptoms in adolescents.Methods:Since 2013, 2 084 students in grade 1-3 were selected from two primary schools in Bengbu, Anhui Province were selected by using convenience sampling method to establish the adolescence pubertal development cohort. Followed up for 6 years, physical examination, secondary sexual development evaluation (testicular volume for boys and breast development for girls) and depressive symptoms were evaluated biennially. Non-linear growth model was used to estimate pubertal timing and tempo for boys and girls respectively. Depressive symptoms were interviewed by using the Short Mood & Feeling Questionnaire (SMFQ) at baseline and Mood & Feeling Questionnaire (MFQ) during follow-up for students in grade 1-2. Children Depression Inventory (CDI) was used for students in grade 3 at baseline and during follow-up. Depressive symptom scores were standardized by using the Z-score method. Multivariate linear regression model was used to analyze the predictive effects of modeling pubertal timing and tempo on depressive symptoms of adolescence boys and girls. Results:There were 1 909 students with complete questionnaire and puberty development information, including 1 052 boys (59.19%) and 857 girls (43.81%), with average age about (13.94±0.87) years and 91.60 percent follow-up rate. The average modeling pubertal timing of girls (11.25 years) was earlier than that of boys (12.70 years), and the average pubertal tempo of girls about 1.47 Tanner stage/year was faster than that of boys about 1.28 Tanner stage/year. After controlling for depressive symptoms, maternal education and adverse childhood experiences at baseline and age, body mass index (BMI) classification and sleep time during follow-up, this predictive effect of pubertal timing and tempo on depressive symptoms was only significant among girls. Compared with girls with on time pubertal timing, girls in the delay timing group had a lower level of depressive symptoms (β=-0.19, 95% CI:-0.34,-0.01). Compared with girls in average pubertal tempo group, the fast tempo group associated with an increasing risk of depressive symptoms (β =0.23, 95% CI: 0.05, 0.40), while the slow tempo group associated with an decreasing risk of depressive symptoms (β =-0.21, 95％ CI:-0.39,-0.03). Insignificant effects were found in puberty timing and tempo on depressive symptoms of boys ( P>0.05). Conclusion:Fast pubertal tempo increases the risk of development of depressive symptoms of adolescent girls. There is no predictive effect of pubertal timing and tempo on depression symptoms of adolescent boys.
