ObjectiveTo investigate the potential mechanism of Danggui Buxuetang (DBT) in the treatment of vascular dementia (VAD). MethodsSixty male SD rats were randomly assigned to the sham-operated group, model group, DBT low-, medium-, and high-dose groups, and the donepezil group. Except for the sham-operated group, rats in all other groups underwent bilateral common carotid artery ligation. After successful modeling, DBT was administered at doses of 9.2, 18.4, 36.8 g·kg-1 for the low-, medium-, and high-dose groups, respectively, while the donepezil group received 3 mg·kg-1 donepezil solution by gavage once daily. After 4 consecutive weeks of drug treatment, rats underwent the Morris water maze test, novel object recognition test, Nissl staining to observe hippocampal neurons, and immunofluorescence staining to detect the expression of neuronal nuclear protein (NeuN) in the hippocampus. Western blot was used to assess the expression of PTEN-induced kinase 1 (PINK1), Parkin, microtubule-associated protein 1 light chain 3Ⅱ (LC3Ⅱ), B-cell lymphoma-2 (Bcl-2), and Bcl-2-associated X protein (Bax). Transmission electron microscopy was used to observe hippocampal neuronal ultrastructure. Real-time PCR was used to detect the expression of NADPH oxidase subunits p22phox and p47phox in hippocampal tissues. The levels of malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), and total antioxidant capacity were measured to evaluate oxidative stress levels. ResultsIn the Morris water maze test, escape latency changed significantly over time in all groups except the model group. Compared with the sham-operated group, the model group showed significantly prolonged escape latency (P<0.01). Compared with the model group, rats in the DBT groups and the donepezil group exhibited significantly shorter escape latency (P<0.05, P<0.01). The number of crossings over the original platform was significantly reduced in the model group compared with the sham-operated group (P<0.01), whereas rats in the DBT and donepezil groups showed significantly increased platform crossings compared with the model group (P<0.05, P<0.01). Compared with the sham-operated group, exploration time of new objects was significantly reduced in the model group (P<0.01). Compared with the model group, exploration time of new objects increased significantly in the medium- and high-dose DBT groups and the donepezil group (P<0.05, P<0.01), while no significant change was observed in the low-dose DBT group. Compared with the high-dose DBT group, rats in the donepezil group had significantly prolonged escape latency and reduced platform crossings and new-object exploration time (P<0.05). Nissl staining showed decreased density of healthy neurons in the CA1 and CA3 regions of the hippocampus in the model group, with loss of Nissl bodies and nuclear atrophy or disappearance. In the high-dose DBT group, neuronal density in CA1 and CA3 increased, with neurons arranged closely and displaying normal morphology. Immunofluorescence showed that compared with the sham-operated group, the hippocampal NeuN⁺ cell count in the VAD model group was significantly decreased(P<0.01), compared with the VAD model group, the hippocampal NeuN⁺ cell count in the high-dose DBT group was significantly increased(P<0.01). Compared with the sham-operated group, the expression of PINK1, Parkin, LC3Ⅱ, and Bax proteins was significantly increased(P<0.01), while the expression of Bcl-2 was significantly decreased in the VAD model group(P<0.01). Compared with the VAD model group, the high-dose DBT group showed significantly decreased expression of PINK1, Parkin, LC3Ⅱ, and Bax proteins(P<0.01)and significantly upregulated Bcl-2 expression(P<0.01). The medium-dose DBT group exhibited significantly reduced expression of Parkin, LC3Ⅱ, and Bax proteins(P<0.05,P<0.01) and significantly increased Bcl-2 expression(P<0.01), while no statistically significant differences were observed in the low-dose DBT group. Transmission electron microscopy showed mitochondrial pyknosis, thickened cristae, increased electron density, and the presence of mitochondrial autophagy in the model group. In contrast, hippocampal neurons in the high-dose DBT group contained abundant mitochondria with intact morphology, clear cristae, and uniform matrix. Compared with the sham-operated group, total antioxidant capacity, SOD activity, and GSH levels were significantly decreased, while MDA levels were significantly increased in the model group (P<0.01). Compared with the model group, total antioxidant capacity and antioxidant levels (SOD, GSH) increased significantly, and MDA decreased significantly in the medium- and high-dose DBT groups (P<0.01), while no significant changes were observed in the low-dose DBT group. Compared with the sham-operated group, mRNA expression of p22phox and p47phox was significantly increased in the model group (P<0.01). Compared with the model group, expression of p22phox and p47phox was significantly decreased in the DBT groups (P<0.05, P<0.01). ConclusionDBT may exert neuroprotective effects by regulating PINK1/Parkin-mediated mitochondrial autophagy, thereby improving learning and memory abilities and treating VAD.

In recent years, with the extensive application of traditional Chinese medicine (TCM) both domestically and internationally, safety concerns associated with TCM have been frequently reported. Notably, some TCM substances traditionally regarded as ''non-toxic'' have exhibited significant adverse reactions during clinical use, drawing substantial attention to TCM safety. This study first analyzed the risk factors contributing to the potential toxicity of TCM from perspectives such as drug properties, individual constitution, and clinical medication practices. Subsequently, it proposed research strategies and methodologies for investigating potential TCM toxicity: ① conduct studies under the guidance of TCM theory, adhering to the principle of diversity and unity. ② adopt an integrated research paradigm of ''originating from clinical practice-syndrome-based foundation-returning to clinical practice-serving supervision''. ③ implement a three-tier technical system of ''Mathematical modeling-high-throughput screening via liquid chromatography-mass spectrometry (LC-MS)-systems biology'' to systematically elucidate the causes, material basis, and mechanisms of toxicity. Finally, scientific regulatory recommendations for potential TCM toxicity are proposed: ① establish a multidimensional prevention and control system addressing drug properties, physical constitution factors, and clinical medication practices. ② address the impact of modern processing techniques on the safety of new TCM drugs. ③ strengthen the revision of standards for Chinese medicinal materials to ensure their safety. ④ account for disease-syndrome combination animal models and interspecies differences in safety assessment outcomes. This study aims to overcome critical challenges in TCM regulation by advancing evaluation through research and driving research through evaluation. By establishing a high-level scientific regulatory framework, it seeks to not only safeguard clinical medication safety but also propel the high-quality development of the TCM industry, thereby providing scientific support for the inheritance and innovative evolution of TCM.

OBJECTIVE To investigate the effects of subanesthetic dose of esketamine on postoperative anxiety and recovery in patients undergoing laparoscopic cholecystectomy. METHODS A total of 200 patients scheduled for laparoscopic cholecystectomy at Suzhou Ninth Hospital Affiliated to Soochow University from January 2023 to December 2024 were randomly assigned to control group (n=100) and observation group (n=100). One minute before the initiation of anesthesia, patients in the control group received intravenous injections of Propofol emulsion injection, Sufentanil citrate injection, and Succinylcholine chloride injection. On this basis, patients in the observation group received an intravenous injection of Esketamine hydrochloride injection. The anxiety status of patients in both groups was compared, along with their general intraoperative conditions (including sufentanil dosage, duration of pneumoperitoneum, operative time, anesthesia time, and extubation time), postoperative recovery, incidence of adverse reactions, and the need for dezocine rescue analgesia. Heart rate and mean arterial pressure, entropy index (state entropy and response entropy), inflammatory marker levels [interleukin-6 (IL-6) and C-reactive protein (CRP)], numerical rating scale (NRS) for pain intensity were compared between the two groups at different time points. RESULTS No significant differences were found between the two groups in pneumoperitoneum duration, operative time, anesthesia time,extubation time, incidence of postoperative dry mouth, entropy index or length of stay in the post-anesthesia care unit (P>0.05). Compared with the control group, the observation group showed significantly lower postoperative STAI-S scores, reduced intraoperative sufentanil consumption, decreased incidence of postoperative nausea, vomiting, and shivering, the need for dezocine rescue analgesia, as well as lower plasma IL-6 and CRP levels at 24 h after surgery, and NRS (P<0.05). The heart rate and mean arterial pressure of patients in the observation group at the start of surgery, end of surgery, and during extubation were all significantly higher than those in the control group (P<0.05). CONCLUSIONS Subanesthetic dose of esketamine can effectively alleviate postoperative anxiety, reduce intraoperative opioid consumption, suppress postoperative inflammatory response, relieve postoperative pain, and promote recovery in patients undergoing laparoscopic cholecystectomy.

At present, the treatment of sepsis depends largely on non-specific methods, highlighting an urgent need for novel therapeutic strategies. Stem cells have garnered significant attention in the treatment of various diseases due to their unique biological properties. Stem cells enhance sepsis survival through mechanisms such as reducing bacterial burden, modulating inflammation, and ameliorating organ dysfunction. Recent studies have shown that stem cells can increase the survival rate of sepsis patients through multiple pathways such as reducing the bacterial load of the host, regulating inflammatory homeostasis, and improving multi-organ dysfunction. Their derivatives, exosomes, can also alleviate the imbalanced immune response in sepsis patients. Recent advances in stem cell-based therapies for sepsis were summarized in this paper.

Innovation entities bear primary responsibility for the management of scientific and technological ethics. Understanding the current construction status of the scientific and technological ethical governance capacity among Chinese innovation entities is conducive to grasping effectiveness and shortcomings of scientific and technological ethical governance of innovation entities, providing a scientific basis and practical guidance for innovation entities to fulfill their primary responsibilities better. Based on a questionnaire survey targeting 313 innovation entities, this paper investigated and analyzed the current status and existing challenges of scientific and technological ethical governance capacity among Chinese innovation entities from five aspects. It was found that China has made certain achievements in scientific and technological ethical governance, yet there were still issues such as incomplete construction of regulatory systems, low efficiency of ethical review, unestablished regular education and training systems, and imperfect dynamic monitoring systems for ethical risks. Among these issues, the scientific and technological ethical governance capacity of enterprises was identified as requiring urgent improvement. Additionally, strengthening multi-stakeholder collaboration remained a key challenge in building a collaborative and co-governance system for scientific and technological ethics. Based on these issues identified in the survey, countermeasures and suggestions were proposed from five perspectives, that is, enhancing the capacity in institutional construction, ethical review, value transmission, risk early warning, and collaborative governance of innovation entities on scientific and technological ethical governance. The aim was to provide references for accelerating the construction of the scientific and technological ethical governance system and improving the scientific and technological ethical governance capacity of innovation entities.

Thyroid diseases are common clinical endocrine disorders, and their pathogenesis is generally considered to be closely related to genetic predisposition factors, immune system disorders, hormone levels, etc. Xiaoyaosan is widely used in the treatment of various thyroid diseases with excellent effects. This study summarized the relevant literature on the treatment of thyroid diseases with modified Xiaoyaosan prescriptions and their active ingredients from aspects such as theoretical analysis, clinical research, and mechanism research. Theoretical analysis revealed that Xiaoyaosan could not only disperse stagnated liver qi but also replenish deficient spleen Qi, which was consistent with the etiology and pathogenesis of thyroid diseases. Clinical studies found that Xiaoyaosan and its modified prescriptions could be widely used in the treatment of multiple thyroid diseases, such as hyperthyroidism, Hashimoto's thyroiditis, and thyroid nodules. Both the use of modified Xiaoyaosan alone and in combination with medications such as methimazole, propylthiouracil, and euthyrox could effectively improve patients' clinical symptoms. In the mechanism research, this study discovered that the whole formula of Xiaoyaosan and its modified prescriptions could inhibit inflammatory reactions, regulate immune balance, and delay liver damage during the treatment of thyroid diseases. The research on Xiaoyaosan for treating thyroid diseases mainly focused on thyroid cancer, autoimmune thyroiditis, hyperthyroidism, and hypothyroidism. The mechanisms of action mainly involved promoting cell apoptosis, inhibiting cell proliferation and migration, arresting the cell cycle, and regulating thyroid hormone levels. In conclusion, this study systematically combs and summarizes the research status of Xiaoyaosan in treating thyroid diseases through literature retrieval, aiming to provide new perspectives and new ideas for the prevention and treatment of thyroid diseases with traditional Chinese medicine.

AIM: To observe the influence of different intraocular lens implantation methods on visual quality in patients with cataract.METHODS: Retrospective study. Totally 85 patients(113 eyes)with cataract who received phacoemulsification combined with intraocular lens implantation in the hospital June 2020 to December 2023 were selected. According to the different implanted lenses, they were divided into monofocal group(42 cases, 55 eyes)and bifocal group(43 cases, 58 eyes). The uncorrected near visual acuity(UNVA), uncorrected intermediate visual acuity(UIVA), uncorrected distance visual acuity(UDVA), best corrected near visual acuity(BCNVA), best corrected intermediate visual acuity(BCIVA), best corrected distance visual acuity(BCDVA), contrast sensitivity(CS), objective visual quality, National Eye Institute 25-item Visual Function Questionnaire(NEI-VFQ-25)scores and complications were compared between both groups of patients at 3 mo after surgery.RESULTS:At 3 mo after surgery, the UNVA(LogMAR)of the bifocal group was significantly better than that of the monofocal group(0.24±0.06 vs 0.53±0.13, P<0.001), but there were no statistical differences in UIVA, UDVA, BCNVA, BCIVA and BCDVA between the two groups(all P>0.05). The 18 c/d spatial frequency scotopic CS in the bifocal group at 3 mo after surgery was significantly lower than that in the monofocal group(0.84±0.17 vs 0.92±0.22, P<0.05), while the CS in other frequency was not statistically significant(all P>0.05); the objective scatter index(OSI)was higher in the bifocal group than that in the monofocal group(P<0.05), while OV 20% and OV 9% were lower than those in monofocal group(all P<0.05), but there were no statistically significant differences in modulation transfer function cut off(MTFcut off), Strehl ratio(SR)and OV 100% between the two groups(all P>0.05). The scores of overall visual acuity and near visual activity in the bifocal group at 3 mo after surgery were higher than those in the monofocal group(all P<0.001), but there were no statistical differences in the scores of dimensions of overall health, distance visual activity, peripheral visual acuity, color vision, dependence degree, social function, social role and mental health between the two groups(all P>0.05). Furthermore, there were no statistical significance in the incidence of complications in the two groups(P>0.05).CONCLUSION: Phacoemulsification combined with bifocal intraocular lens implantation can provide more ideal near visual acuity and visual-related quality of life for patients with cataract, but its objective visual quality is worse, The two types of intraocular lenses have their own advantages and disadvantages, and it is still necessary to choose the appropriate intraocular lens according to the actual needs of patients.
