OBJECTIVE: To observe the clinical efficacy of acupuncture based on the "head qijie" theory combined with endovascular intervention in the treatment of ischemic stroke (IS). METHODS: Sixty-six IS patients were randomly divided into an experimental group (33 cases, 3 cases dropped out) and a control group (33 cases, 3 cases dropped out). The control group received endovascular intervention. On the basis of the treatment in the control group, the experimental group received acupuncture based on the "head qijie" theory starting from the second day after surgery, Baihui (GV20) and bilateral Fengchi (GB20), Tianzhu (BL10), etc. were selected, once a day, 6 times a week for 2 weeks. Before and after treatment, the scores of National Institutes of Health stroke scale (NIHSS), modified Barthel index (MBI) and modified Rankin scale (mRS) were observed in the two groups, the clinical efficacy and safety were evaluated. RESULTS: After treatment, the NIHSS and mRS scores were decreased compared with those before treatment in both groups (P<0.01), the NIHSS and mRS scores in the experimental group were lower than those in the control group (P<0.05). After treatment, the MBI scores were increased compared with those before treatment in both groups (P<0.01), the MBI score in the experimental group was higher than that in the control group (P<0.05). The total effective rate in the experimental group was 86.7% (26/30), which was higher than 66.7% (20/30) in the control group (P<0.05). The incidence of adverse events in the experimental group was 6.7% (2/30), which was lower than 13.3% (4/30) in the control group (P<0.05). CONCLUSION Acupuncture based on the "head qijie" theory combined with endovascular intervention in treating IS has good efficacy, improves neurological function, and enhances daily living ability.

The aging microenvironment, as a key driver of tumorigenesis and progression, plays a critical role in tumor immune regulation through one of its core features-the senescence-associated secretory phenotype (SASP). SASP consists of a variety of interleukins, chemokines, proteases, and growth factors. It initially induces surrounding cells to enter a state of senescence through paracrine mechanisms, thereby creating a sustained inflammatory stimulus and signal amplification effect within the tissue microenvironment. Furthermore, these secreted factors activate key signaling pathways such as NF-κB, cGAS-STING, and mTOR, which regulate the expression of immune-related molecules (such as PD-L1) and promote the recruitment of immunosuppressive cells, including regulatory T cells and myeloid-derived suppressor cells. This process ultimately contributes to the formation of an immunosuppressive tumor microenvironment. Furthermore, the article explores potential anti-tumor immunotherapy strategies targeting SASP and its associated molecular mechanisms, including approaches to inhibit SASP secretion or eliminate senescent cells. Although these strategies have shown promise in certain tumor models, the high heterogeneity among tumor types may result in varied responses to SASP-targeted therapies. This highlights the need for further research into adaptive stratification and personalized treatment approaches. Targeting immune regulatory mechanisms in the aging microenvironment-particularly SASP-holds great potential for advancing future anti-tumor therapies.

Anxiety disorder is a major symptom of autism spectrum disorder (ASD) with a comorbidity rate of ~40%. However, the neural mechanisms of the emergence of anxiety in ASD remain unclear. In our study, we found that hyperactivity of basolateral amygdala (BLA) pyramidal neurons (PNs) in Shank3 InsG3680 knock-in (InsG3680^+/+) mice is involved in the development of anxiety. Electrophysiological results also showed increased excitatory input and decreased inhibitory input in BLA PNs. Chemogenetic inhibition of the excitability of PNs in the BLA rescued the anxiety phenotype of InsG3680^+/+ mice. Further study found that the diminished control of the BLA by medial prefrontal cortex (mPFC) and optogenetic activation of the mPFC-BLA pathway also had a rescue effect, which increased the feedforward inhibition of the BLA. Taken together, our results suggest that hyperactivity of the BLA and alteration of the mPFC-BLA circuitry are involved in anxiety in InsG3680^+/+ mice.

Intentional tooth replantation (ITR) is an advanced treatment modality and the procedure of last resort for preserving teeth with inaccessible endodontic or resorptive lesions. ITR is defined as the deliberate extraction of a tooth; evaluation of the root surface, endodontic manipulation, and repair; and placement of the tooth back into its original socket. Case reports, case series, cohort studies, and randomized controlled trials have demonstrated the efficacy of ITR in the retention of natural teeth that are untreatable or difficult to manage with root canal treatment or endodontic microsurgery. However, variations in clinical protocols for ITR exist due to the empirical nature of the original protocols and rapid advancements in the field of oral biology and dental materials. This heterogeneity in protocols may cause confusion among dental practitioners; therefore, guidelines and considerations for ITR should be explicated. This expert consensus discusses the biological foundation of ITR, the available clinical protocols and current status of ITR in treating teeth with refractory apical periodontitis or anatomical aberration, and the main complications of this treatment, aiming to refine the clinical management of ITR in accordance with the progress of basic research and clinical studies; the findings suggest that ITR may become a more consistent evidence-based option in dental treatment.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Objective:To evaluate the effects of electroacupuncture (EA) on the learning and memory function of offspring rats exposed to sevoflurane in late-pregnancy.Methods:Thirty-two SPF healthy Sprague-Dawley pregnant rats at gestational day 18, weighing 260-280 g, were assigned to 4 groups ( n=8 each) using a random number table method: control group (C group), sevoflurane group (Sev group), EA group and sham EA group (SEA group). Sev, SEA and EA groups inhaled 2.5% sevoflurane in 50% oxygen for 6 h. In EA group, Shenting, Baihui, bilateral Quchi, and bilateral Zusanli points were stimulated with an electric stimulator (disperse-dense waves, frequency 2/6 Hz, intensity 1 mA, 20 min per day for 7 consecutive days) starting on postnatal day 21, EA was performed again for 7 days after an interval of 1 day, and the EA treatment lasted for a total of 14 days. Moriss water maze test was performed at 36 days of age to detect the spatial learning and memory function. The offspring rats were sacrificed on postnatal day 42, and the hippocampal tissues were removed for calculation of the dendritic spine density of neurons (after Golgi staining) and for determination of the apoptosis rate (using flow cytometry) and the expression of the two primary forms of brain-derived neurotrophic factor (BDNF), mature (mBDNF) and pro (proBDNF), mBDNF/proBDNF ratio, tropomyosin receptor kinase B (TrkB) and p75 neurotrophin receptor (p75NTR) (by Western blot). The mBDNF/proBDNF ratio was calculated. Results:Compared with C group, the escape latency was significantly prolonged, the time of staying at the target platform quadrant was shortened, the frequency of crossing the original platform was reduced, the dendritic spine density of hippocampal neurons and mBDNF/proBDNF ratio were decreased, the expression of TrkB was down-regulated, and the expression of p75NTR was up-regulated in Sev groups ( P<0.05). Compared with the offspring rats of Sev and SEA groups, the escape latency was significantly shortened, the time of staying at the target platform quadrant was prolonged, the frequency of crossing the original platform was increased, the dendritic spine density of hippocampal neurons and mBDNF/proBDNF ratio were increased, the expression of TrkB was up-regulated, and the expression of p75NTR was down-regulated in the offspring rats of EA group ( P<0.05), and no significant change was found in the aforementioned parameters in the offspring rats of SEA group ( P>0.05). There was no significant difference in the apoptosis rate of hippocampal neurons among the offspring rats of the four groups ( P>0.05). Conclusions:EA can improve the learning and memory function of offspring rats exposed to sevoflurane in late-pregnancy, and the mechanism may be related to promoting the conversion of proBDNF to mBDNF and improving neuronal development.

Objective To investigate the correlation between the level of N-terminal pro-Brain natriuretic peptide(NT-proBNP)and cardiorespiratory fitness following acute exposure to high altitude.Methods Forty-six subjects were recruited from the Second Affiliated Hospital of Army Medical University in June 2022,including 19 males and 27 females.After completing cardiopulmonary exercise test(CPET),serological detection of myocardial cell-related markers,and multiple metabolites at a plain altitude(300 meters above sea level),all subjects flew to a high-altitude location(3900 meters above sea level).Biomarker testing and CPET were repeated on the second and third days after arrival at high altitude.Changes in serum biomarker and key CPET indicators before and after rapid ascent to high altitude were compared,and the correlation between serum levels of various myocardial cell-related markers and metabolites and high altitude cardiorespiratory fitness was analyzed.Results Compared with the plain altitude,there was a significant decrease in maximal oxygen uptake after rapid ascent to high altitude[(25.41±6.20)ml/(kg.min)vs.(30.17±5.01)ml/(kg.min),P<0.001].Serum levels of NT-proBNP,Epinephrine(E),plasma renin activity(PRA),angiotensin Ⅱ(Ang Ⅱ),angiotensin-converting enzyme 2(ACE2)and leptin(LEP)significantly increased,with all differences being statistically significant(P<0.05)after acute high altitude exposure.In contrast,no statistically significant differences were observed for creatine kinase MB(CK-MB),cardiac troponin I(cTnI),myoglobin(Myo)and norepinephrine(NE)(P>0.05).Correlation analysis showed a significant negative correlation between NT-proBNP at plain altitude(r=-0.768,P<0.001)and at high altitude(r=-0.791,P<0.001)with maximal oxygen uptake at high altitude.Multivariate linear regression analysis indicated that maximal oxygen uptake at plain altitude(t=2.069,P=0.045),NT-proBNP at plain altitude(t=-2.436,P=0.020)and at high altitude(t=-3.578,P=0.001)were independent influencing factors of cardiorespiratory fitness at high altitude.Conclusion Cardiorespiratory fitness significantly decreases after rapid ascent to high altitude,and the baseline NT-proBNP level at plain altitude is closely related to cardiorespiratory fitness at high altitude,making it a potential predictor indicator for high altitude cardiorespiratory fitness.
