Diabetic cognitive impairment （DCI） has an insidious onset and progressive and irreversible development. There is currently no first-line treatment for DCI. Early intervention of diabetes with traditional Chinese medicine （TCM） can effectively control blood sugar and improve cognitive impairment， which has significant advantages. As a representative of bitter and cold heat-clearing medicines， Coptidis Rhizoma， known for its abilities to clear heat and dampness and remove turbidity and toxins， has been widely used in the clinical prevention and treatment of diabetes， Alzheimer's disease， vascular dementia， and other cognitive impairments. This article systematically summarized relevant literature and observed that Coptidis Rhizoma has shown good potential in the prevention and treatment of DCI with its active ingredients such as berberine and quercetin， drug pairs such as Coptidis Rhizoma-Scutellariae Radix， Coptidis Rhizoma-Acorus Tatarinowii Rhizoma， Coptidis Rhizoma-Pinelliae Rhizoma， Coptidis Rhizoma-Zingiberis Rhizoma， and prescriptions such as Gegen Qinliantang， Huanglian Jiedutang， Banxia Xiexintang， Huanglian Wendantang， Jiaotai Wan， Danggui liuhuangtang， and related Chinese patent medicines. Its mechanism may be related to regulating glucose metabolism， improving insulin resistance， improving amyloid β-protein （Aβ） deposition and tau protein phosphorylation， inhibiting neuroinflammation and oxidative stress， and regulating the "microbe-gut-brain axis". The article systematically reviewed the research progress of Coptidis Rhizoma and its prescriptions in the prevention and treatment of DCI， aiming to preliminarily explain the scientific connotation of Coptidis Rhizoma and provide a basis for its clinical application in the prevention and treatment of DCI.

convalescents, and to screen for broad-spectrum neutralizing antibodies against the SARS-CoV-2 RBD. Methods Using biotinylated RBD as a molecular probe, flow cytometry was employed to perform single-cell sorting of B cells from peripheral blood mononuclear cells (PBMCs) of convalescents. The obtained B cells were lysed and subjected to reverse transcription, followed by nested PCR amplification of the heavy and light chains of antibodies was conducted using random primers. The amplified products were cloned into corresponding expression vectors, and the respective matched heavy-light chain plasmids were co-transfected into 293F cells for expression. Monoclonal antibodies were then purified using Protein A column chromatography. Neutralization experiments were conducted with the wild-type (WT) pseudovirus, and antibodies with IC50<0.1 μg/mL were selected for further testing of neutralizing breadth and potency against the wild-type (WT), Beta variant (B.1.351), Delta variant (B.1.617.2), and currently prevalent pseudovirus strains (XBB, BA.5, BF.7). Results A total of 21 RBD-specific monoclonal B cells were obtained from two recovered patients, resulting in the isolation of 13 pairs of antibody light/heavy chains. Nine antibodies were successfully expressed, with P1-A1, P1-B6, and P1-B9 exhibiting IC50 values below 0.1 μg/mL against the pseudovirus of the wild-type strain (WT). Specifically, P1-B6 effectively neutralized the wild-type strain (WT), Beta variant (B.1.351), and Delta variant (B.1.617.2), with IC50 values reaching 0.01 μg/mL. P1-B9 demonstrated effective neutralization against the wild-type strain (WT), Beta variant (B.1.351), Delta variant (B.1.617.2), and Gamma variant (P.1) pseudoviruses, with IC50 values of 0.42 μg/mL, 0.63 μg/mL, 0.28 μg/mL, and 2.50 μg/mL, respectively. Additionally, P1-B6 exhibited good neutralization against BA.5 and BF.7 pseudoviruses, with IC50 values of 0.06 μg/mL and 0.09 μg/mL, respectively. Conclusions Infection with the SARS-CoV-2 WT strain can induce the generation of neutralizing antibodies with broad-spectrum activity. Generating these broadly neutralizing antibodies does not require an excessively high somatic hypermutation. The obtained antibodies can be used as candidates for SARS-CoV-2 diagnosis and prevention.

Objective To investigate the correlation between tibial plateau varus and osteoporosis(OP)in postmenopausal women with knee osteoarthritis(KOA).Methods A retrospective analysis was conducted on 194 postmenopausal women with KOA who underwent unicompartmental knee arthroplasty.Various risk factors associated with tibial plateau varus[medial tibial plateau angle(MTPA)＜85°],including age,body mass index(BMI),Kellgren-Lawrence(K-L)grade,hip-knee-ankle angle(HKAA),lateral distal femur angle(LDFA),bone mineral density(BMD)were collected and analyzed.Multiple regression was employed to analyze the relationship of these factors with tibial plateau varus.Pearson's correlation coefficient was used to assess the association between MTPA and BMD.Results Multiple linear regression analysis revealed that BMD(β=0.381,P＜0.001)and HKAA(β=0.460,P＜0.001)were independent risk factors for tibial plateau varus.LDFA,age,BMI,K-L grade were not significantly associated with tibial plateau varus.A statistically significant association between BMD and tibial plateau varus was noted(r=0.817,P＜0.001).Further data stratification showed a significant association between BMD and tibial plateau varus in patients with knee varus(HKAA＜175°)(r=0.781,P＜0.001).There was no statistical significance association between BMD and tibial plateau varus in patients with normal lower extremity alignment(HKAA≥175°)(r=-0.035,P=0.063).Conclusion OP and knee varus emerge as the primary risk factors for tibial plateau varus in the knee in postmenopausal women with KOA.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Interleukin (IL)-17A, a pro-inflammatory cytokine, is a fundamental function in the onset and advancement of multiple immune diseases. To uncover the primary compounds with IL-17A inhibitory activity, a large-scale screening of the library of traditional Chinese medicine constituents and microbial secondary metabolites was conducted using splenic cells from IL-17A-GFP reporter mice cultured under Th17-priming conditions. Our results indicated that some aureane-type sesquiterpene tetraketides isolated from a wetland mud-derived fungus, Myrothecium gramineum, showed remarkable IL-17A inhibitory activity. Nine new aureane-type sesquiterpene tetraketides, myrogramins A-I ( 1, 4- 11), and two known ones ( 2 and 3) were isolated and identified from the strain. Compounds 1, 3, 4, 10, and 11 exhibited significant IL-17A inhibitory activity. Among them, compound 3, with a high fermentation yield dose-dependently inhibited the generation of IL-17A and suppressed glycolysis in splenic cells under Th17-priming conditions. Strikingly, compound 3 suppressed immunopathology in both IL-17A-mediated animal models of experimental autoimmune encephalomyelitis and pulmonary hypertension. Our results revealed that aureane-type sesquiterpene tetraketides are a novel class of immunomodulators with IL-17A inhibitory activity, and hold great promise applications in treating IL-17A-mediated immune diseases.

Objective:To analyze the correlation between sleep midpoint and sleep quality in insomnia patients with type 2 diabetes mellitus (T2DM).Methods:By adopting current situation investigation research, total of 150 T2DM patients hospitalized in the Department of Endocrinology, the First Affiliated Hospital of Guizhou University of Traditional Chinese Medicine from November 2021 to July 2022 were selected as the research objects. The general information questionnaire, Pittsburgh Sleep Quality Index (PSQI), anxiety scale (SAS) and Depression Scale (SDS) were used to investigate, and then analysis the datum.Results:Among 150 T2DM insomnia patients, 41 cases (27.33%) were in the early midpoint sleep group, 37 cases (24.67%) were in the middle midpoint sleep group, and 72 cases (48.00%) were in the late midpoint sleep group. There were significant differences in the distribution of sex, age and BMI level among different sleep midpoint groups ( χ2=7.24, 13.36, 15.93, all P<0.05). The scores of time to fall asleep at the midpoint of sleep in the 3 groups were (2.12 ± 1.25), (2.65 ± 0.79), (2.33 ± 1.02), the difference was significant ( F=2.14, P<0.05); the daytime disability scores in the 3 groups were (1.39 ± 1.36), (2.16 ± 1.12), (1.85 ± 1.32), the difference was significant ( F=3.17, P<0.05). Logistic regression analysis of disorder showed that the time to fall asleep ( OR=4.922, P<0.05) and daytime disability ( OR=4.043, P<0.05) had significant influence to the middle midpoint of sleep group when the early midpoint of sleep group as the control, while the male ( OR=2.182, P<0.05), 50 - 70 years old ( OR=5.005, P<0.05) and BMI over fat side ( OR=3.488, P<0.05) had significant influence to the late midpoint of sleep group. Conclusions:Medical staff should pay attention to the sleep quality of T2DM patients, pay attention to the sleep midpoint of patients, and improve patients′cognition of healthy sleep patterns.

Purpose: In non-metastatic prostate cancer (nmPCa) setting, it is important to early identify the patients at risk of biochemical recurrence (BCR) for immediate postoperative intervention. Our study aimed to evaluate the potential clinical utility of circulating tumor DNA (ctDNA) for predicting disease recurrence. Materials and Methods: This real-world observational study evaluated 161 cases of nmPCa undergoing next-generation sequencing at our institution. A total of 139 ctDNA samples and 31 biopsied tumor tissue underwent genomic profiling. The study endpoint was BCR after radical prostatectomy. Relationships between the ctDNA status and the biochemical progression-free survival (bPFS) were analyzed by log-rank test and multivariate Cox regression. Results: Of 161 enrolled patients, 19 (11.8%) harbored deleterious alterations in NCOR2, followed by BRCA2 (3.7%), ATR (2.5%), and CDK12 (2.5%). Of available pre-operative blood samples (n=139), ctDNA was detectable in 91 (65.5%). Until last follow-up, 56 of 68 patients (85.3%) with detectable ctDNA had achieved BCR, whereas only eight of 39 patients (20.5%) with undetectable ctDNA had achieved BCR. Patients who had undetectable ctDNA experienced significantly longer bPFS compared with those who had detectable ctDNA (not available vs. 8.2 months; hazard ratio, 0.14; p < 0.01). Pre-operative ctDNA status was a significant prognostic factor of disease recurrence. Conclusion Pre-operative ctDNA detection could identify patients at high risk of recurrence and has the potential to inform immediate postoperative interventions, but these approaches remain to be validated in prospective studies. ctDNA studies can provide insights into accurate monitoring and precise treatment rather than simply following routine clinical care.

  Objective  To understand the current status of surgical treatment for hemophilia osteoarthropathy (HO) in China.  Methods  Using an online questionnaire, select domestic hospitals that partici-pated in the compilation of the 'Guideline for perioperative management of hemophilia patients undergoing orthopaedic surgery in China ', in addition to members of the National Joint Surgery Group, and the Orthopedic Branch of the Chinese Medical Association for targeted investigation and analysis.  Results  A total of 17 domestic hospitals were included, all of which were general hospitals. Hospitals that started HO surgery treatment before 2000 accounted for 35.29%. A total of 3057 surgical cases of HO were reported by those hospitals. The most commonly performed surgical procedures were hip and knee joint replacement. The most commonly used coagulation factor replacement regimen was recombinant coagulation factor preparation. Ten hospitals reported finding patients with transfusion-related infectious diseases. Bleeding and hematoma formation were the most frequently reported surgical complications. Excessive length of hospital stay and high economic costs were the most frequently reported problems.  Conclusions  Surgical treatment for HO in 17 hospitals is mainly carried out in some large comprehensive medical centers in the eastern region. Compared with the patient base, the popularity and number of surgeries are still relatively insufficient. It is necessary to further standardize the treatment system by standardizing factor replacement and strengthening rehabilitation to improve surgical treatment outcomes.

Objective:To analyze the intervention effect of rehabilitation platform-based online psycho-education on patients with bipolar disorder (BD) in remission stage.Methods:In this randomized controlled study, 91 patients with BD in remission stage who attended the community health center in Xicheng District, Beijing from July to August 2021 were randomly divided into a test group (46 cases) and a control group (45 cases) according to a 1∶1 ratio using the random number table. Baseline data were collected from both groups, and the control group received conventional medication and community telephone follow-up, while the test group was given online mental health education in the form of a WeChat subscription number on this basis, including BD mental health education course push (twice a week) and disease self-management (daily recording of mood, sleep, medication, exercise and gratitude diary), and the intervention period was 6 months in both groups. During the intervention, one patient in the test group was admitted to hospital due to exacerbation of mental illness and the trial was terminated. A total of 90 cases were included in the study. The scores of Medication Adherence Rating Scale (MARS), Hamilton Depression Scale (HAMD), Young Mania Rating Scale (YMRS) and Perceived Devaluation-Discrimination Scale (PDD) were assessed at baseline, after 3 months and 6 months of intervention in both groups, respectively. And the differences in baseline data between the two groups were compared using two independent samples t test and χ2 test, and the repeated-measures ANOVA was used to compare the differences in MARS, HAMD, YMRS, and PDD scores between the two groups before and after the intervention, and to analyze the intervention effects of network mental health education based on the rehabilitation platform on patients in remission stage of BD. Results:After 6 months of intervention, MARS scores in the test group was significantly higher than that in the control group [(8.47±1.75) vs (7.47±1.85)], and was significantly higher than that at baseline (7.36±2.13) and after 3 months of intervention (8.04±1.68) (all P<0.05). YMRS and PDD scores in the test group were significantly lower than those at baseline after 3 and 6 months of intervention [YMRS, 2.0(1.0,4.0),2.0(0,3.0) vs 3.0(1.0,5.5); PDD, (31.18±4.65), (30.13±4.76) vs (32.51±4.51)] (all P<0.05); the differences in YMRS and PDD scores in the control group were not statistically significant (all P>0.05). There was no statistically significant difference in HAMD scores between the two groups before and after the intervention (all P>0.05). Conclusion:Combining mental health education based on rehabilitation platform with conventional medication and community management can significantly improve the medication compliance of patients with BD in remission stage, and improve their manic symptoms and reduce the stigma of the disease.

Objective:To explore the ability of sequential immunization regimen inducing neutralizing antibodies against severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) Wuhan-Hu1 and Omicron variants in mice.Methods:Groups of 6-8-week-old BALB/c mice were primed with two doses of Wuhan-Hu-1 inactivated vaccine, and then boosted with Omicron or Wuhan-Hu-1 inactivated vaccine, respectively. Binding antibodies were tested by enzyme linked immunosorbent assay; and neutralizing antibodies against Wuhan-Hu1 and Omicron variants were analyzed by vesicular stomatitis virus pseudovirus assay system; SARS-CoV-2 specific cellular immune responses were quantified by enzyme-linked immunosorbent spot assay.Results:IgG antibodies against Wuhan-Hu1, Delta and Omicron RBD were enhanced after the second dose of Wuhan-Hu1 inactivated vaccine. Compared with Wuhan-Hu1 inactivated vaccine, the group boosted with Omicron inactivated vaccine improved Wu-RBD and Omic-RBD specific IgG antibodies 1.41 and 1.26 times, and serum neutralizing antibodies against BA.1, BA.2, BA.4/5 and BF.7 were elevated 4.5, 3.4, 12.1 and 6.5 folds, respectively, by sequential immunization. After booster immunization with inactivated Wuhan-Hu1 or Omicron vaccines, Wu-RBD IgA titer was significantly higher than that of one dose inactivated Wuhan-Hu1 vaccine ( P=0.005 7, P=0.006 1). Conclusions:Neutralizing antibodies against Omicron variants were enhanced by sequential immunization with Omicron inactivated vaccine. Specific IgA was significantly enhanced after the third dose of inactivated vaccine.
