The c-Jun N-terminal kinase （JNK） signaling pathway， a key member of the mitogen-activated protein kinase （MAPK） family， plays a central role in the pathogenesis and progression of central nervous system （CNS） diseases by regulating core biological processes such as apoptosis， inflammatory responses， synaptic plasticity， and autophagy. This article sorts out and analyzes relevant literature published domestically and internationally in recent years， summarizing the mechanisms of action of the JNK signaling pathway in common CNS diseases and the research progress in traditional Chinese medicine （TCM） interventions in CNS diseases through the regulation of the JNK signaling pathway. Studies have shown that active components of TCM， such as berberine， paeoniflorin， and astragaloside Ⅳ， as well as compound formulations like Heixiaoyao san， Ditan tang， and Buyang huanwu tang， can exert neuroprotective effects in various CNS disorders， including Alzheimer’s disease， Parkinson’s disease， cerebral ischemia-reperfusion injury， and epilepsy， by inhibiting the aberrant activation of the JNK signaling pathway， thereby alleviating neuroinflammation， oxidative stress， and neuronal apoptosis， while improving synaptic function and cognitive behavioral deficits， regulating autophagy， and maintaining blood-brain barrier integrity.

The Pharmacovigilance Guidelines for Clinical Application of Oral Chinese Patent Medicines （hereinafter referred to as the Guidelines） is first specialized in the field of drug safety for oral Chinese patent medicines （OCPMs） in China. Rooted in China's healthcare context， the Guidelines address the unique usage patterns and risk characteristics of OCPMs， filling a regulatory gap in the pharmacovigilance framework specific to this category. To facilitate accurate understanding and effective implementation of the Guidelines， and to promote the standardized development of pharmacovigilance practices for OCPMs， this study offered a systematic interpretation based on its three core components. In the domain of risk monitoring and reporting， the paper analyzed the rationale for multi-source information integration and clarified the criteria for identifying key products and target populations for intensive monitoring. Regarding risk assessment， the Guidelines were examined from three dimensions of formulation components， medication behaviors， and population to address complex safety issues arising from medicinal constituents， irrational use， and individual susceptibility. In the area of risk control， the analysis focused on context-based interventions and dynamic closed-loop management strategies， exploring practical pathways to shift from passive response to proactive risk mitigation. Furthermore， this paper evaluated the applied value of the Guidelines and identified implementation challenges， such as insufficient capacity at the primary-care level and limited digital infrastructure. In response， the study proposed optimization strategies including establishing a dynamic updating mechanism， strengthening training at the grassroots level， and incorporating artificial intelligence to enhance pharmacovigilance capacity. This interpretation aims to provide actionable insights for marketing authorization holders （including manufacturers）， pharmaceutical distributors， healthcare institutions， and research organizations， ultimately supporting the establishment and refinement of a full lifecycle pharmacovigilance system for OCPMs.

Alzheimer’s disease （AD） is an age-related neurodegenerative disorder. Marrow-sea insufficiency serves as the fundamental basis for the onset of AD. Early syndrome differentiation-based intervention helps to delay disease progression， and improve patients’ cognitive function. Qifu yin is a representative specialized prescription for AD with marrow-sea insufficiency syndrome. Studies demonstrate that Qifu yin exerts neuroprotective effects through multiple pathways， including inhibiting the abnormal deposition of amyloid β -protein and hyperphosphorylation of tau protein， alleviating neuroinflammation， regulating oxidative stress and mitochondrial dysfunction， modulating the cholinergic system， and improving synaptic plasticity. Qifu yin combined with Western medicine such as donepezil， memantine， and butylphthalide， or combined with external therapies such as acupuncture， can effectively improve cognitive function and activities of daily living in AD patients with favorable safety. Future research should focus on the core pathogenesis and key targets of AD with marrow-sea insufficiency syndrome， provide in-depth elucidation of the scientific connotation of Qifu yin’s “tonifying the kidney to produce marrow”， and further conduct high-quality clinical studies to provide scientific evidence for the prevention and treatment of AD with marrow-sea insufficiency syndrome.

BACKGROUND:Osteoblasts are the main cell types responsible for bone formation and remodeling,and the normal performance of their function is precisely regulated by various signaling pathways.Among them,the bone morphogenetic protein and Wnt signaling pathways play a key role in osteogenesis. OBJECTIVE:To review the role of bone morphogenetic protein/Wnt signaling pathway in the regulation of osteoblast function and analyze its changes in different physiological and pathological conditions in order to further reveal the molecular mechanism of bone formation and remodeling. METHODS:The Chinese and English search terms"BMP signaling pathway,Wnt signaling pathway,and osteogenesis"were searched in CNKI,Wanfang,and PubMed databases for original researches published from the inception to June 2023.Totally 61 articles were finally selected for analysis and summary.Using the method of the literature review,the studies of the bone morphogenetic protein/Wnt signaling pathway in regulating osteogenesis were sorted out and analyzed. RESULTS AND CONCLUSION:(1)Bone morphogenetic protein and Wnt signaling pathways play important roles in the differentiation,proliferation,and maturation of osteoblasts.Bone morphogenetic protein signaling pathway mainly regulates the expression of osteogenesis-related genes through the activation of Smad protein.Smad protein enters the nucleus and regulates the expression of genes related to osteogenesis.Different Wnt signaling pathway from bone morphogenetic protein mainly depends on the activation of β-catenin to exert its biological effects.(2)The regulatory effect of bone morphogenetic protein/Wnt signaling pathway will be affected by many factors in different physiological and pathological states.Growth factors,hormones,and mechanical stress can affect the activity of bone morphogenetic protein/Wnt signaling pathway to some extent.(3)Bone morphogenetic protein/Wnt signaling pathway interacts with other signaling pathways in the regulation of osteogenesis,and they together constitute a complex regulatory network.(4)Chinese medicine and natural compounds can promote bone health by regulating signaling pathways,providing new possibilities for treating bone diseases.(5)Future studies can further explore the interaction of bone morphogenetic protein/Wnt signaling pathway and other signaling pathways and its changes in different physiological and pathological conditions,resolve the key nodes and regulation mechanism in the complex network,to provide more precise targets for the treatment of bone-related diseases,and also provide new ideas to reveal the molecular mechanism of bone formation and remodeling.

Objective To investigate the clinical characteristics of patients with chronic abacterial pros-tafitis(CAP),the CAP related factors were analyzed,and a risk prediction model for CAP were constructed and validated.Methods The clinical dataes of 252 suspected CAP patients admitted to the hospital from June 2022 to December 2024 were collected,the patients were divided into modeling set(ni=177)and validation set(n=75)by 7∶3 ratio.Based on the modeling set dataes,the Lasso was used to screen CAP related predictive factors,a logistic multiple factor model was used to analyze the independent influence factors of CAP and a risk prediction model was constructed.The validation set patient dataes were used to plot ROC and DCA and validate the predic-tion model.Results There were 86 cases of CAP in the modeling set,accounting for 48.59％;32 cases of CAP in the validation set,accounting for 42.67％.The Logistic multiple regression analysis showed that BMI,waist to hip ratio,abnormal elevation of IL-8,COX-2,and PGE2 in prostate fluid were independent influence factors of CAP(P＜0.05),a Nomogram column chart based on this was established.The ROC analysis showed that the sensitivity of the model for detecting CAP in the modeling and validation sets were 0.814 and 0.802,respectively,and the specificity were 0.673 and 0.703,respectively.The DCA analysis showed that the net benefit thresholds for model-ing and validation sets by column charts are 0.1～0.9 and 0.2～1.0,respectively.Conclusions The occurrence of CAP is related to the patient's BMI,waist to hip ratio,the levels of IL-8,COX-2,and PGE2 in prostate fluid.The predictive model established based on this is highly accurate and it can help for CAP screening.

Objective:To investigate the association between different types of lung nodules and the risk of lung cancer in a population at high risk of lung cancer and to provide an epidemiologic basis for the comprehensive management of lung nodules.Methods:Using the free lung cancer screening program of low-dose CT (LDCT) in Wenling, Zhejiang Province, we collected baseline and imaging information of high-risk groups for lung cancer who underwent LDCT screening from April 2019 to October 2021 and patients with previous history of lung cancer, tuberculosis, pneumoconiosis, and silicosis were excluded. A total of 28 539 study subjects were included in the analysis, and the follow-up ended on 31 December 2023. Based on the characteristics of the detected pulmonary nodules, the study subjects were classified with no nodules, with solid nodules, with pure ground glass nodules, and with part solid nodules groups. The association between different characteristics of lung nodules and the risk of lung cancer development was analyzed using the Cox proportional hazard regression model with a new diagnosis of lung cancer during the follow-up period as the outcome.Results:The overall detection rate of lung nodules with a mean diameter of ≥3 mm was 76.5%, of which 53.7%, 18.2%, and 4.6% were detected in the solid nodule, pure ground glass nodule, and partially solid nodule groups, respectively. There were statistically significant differences between the different nodule groups in terms of age, gender, BMI, history of toxic exposure education level, smoking status, history of lung disease, and family history of lung cancer (all P<0.05). The median follow-up time of the study population was 3.4 years, and 485 new lung cancer cases were diagnosed during the follow-up period. After adjusting for covariates, the results of multifactorial Cox proportional hazard regression model analysis showed that the risk of lung cancer was higher in pure ground glass nodules and part solid nodules compared with solid nodules, with HR values (95% CI) of 1.89 (1.52-2.35) and 6.49 (5.18-8.14), respectively. The results of subgroup analysis showed that patients in the group of part solid nodules had the highest risk of lung cancer in all strata of the population, followed by patients with pure ground glass nodules. Patients in the solid nodule group who were older or had previous lung disease had a higher risk of lung cancer, and the risk of lung cancer in the part solid nodule group differed between genders. Conclusions:The proportion of lung nodules detected is high in the high-risk group of lung cancer, and among them, patients with pure ground glass and part solid nodules have a higher risk of developing lung cancer. Attention should be paid to the annual follow-up management for patients with solid nodules who are older or who have had lung diseases, as well as for female patients with part solid nodules.

Objective:To investigate the life expectancy of antiretroviral treatment (ART) HIV-infected patients and its trends in Taizhou City, Zhejiang Province from 2014 to 2023.Methods:The data were obtained from the China Information System for Disease Control and Prevention , and the study subjects were HIV-infected patients received ART in Taizhou City. An abbreviated life expectancy table was prepared based on Chiang's method to analyze the differences in life expectancy of HIV-infected patients receiving ART in Taizhou City with different characteristics in 2023 and to compare the trends in life expectancy of patients with different CD4 +T lymphocytes (CD4) counts at the time of initiation of ART from 2014 to 2023. Results:A total of 4 825 patients were enrolled in this study, with a cumulative follow-up of 276 648.56 person-years, and a case-fatality rate of 18.07 (95% CI: 16.48-19.65) /1 000 person-years. In 2023, male patients had lower life expectancy than females in all age groups, and those who were married had higher life expectancy than those who were unmarried and those who were divorced or widowed; patients who had been transmitted heterosexually had lower life expectancy than those who had been transmitted through homosexual transmission. Patients with different CD4 counts at the time of initiating ART had different life expectancies in all age groups. The life expectancy of patients with CD4 counts ≥350 cells/μl when initiating the treatment was higher than that of patients with CD4 counts <200 cells/μl in all age groups. The life expectancy of HIV-infected patients on ART at age 20 and 50 increased from 39.0 years and 19.1 years in 2014 to 46.0 years and 24.1 years in 2023, respectively, with an average annual percentage change of 2.43% (95% CI: 0.81%-4.07%) and 3.34% (95% CI: 1.17%-5.56%). The change in life expectancy was similar for patients with CD4 counts ≥350 cells/μl and 200-349 cells/μl at the time of initiating treatment in 2016-2023, and was higher than that for patients with CD4 counts <200 cells/μl. The rate of increase in life expectancy for patients at age 50 was higher than that at age 20 for all CD4 counts. Conclusions:The rising trend of life expectancy among HIV-infected patients on ART in Taizhou City is obvious. But the disparity between patients with different characteristics is obvious, especially among patients with baseline CD4 counts <200 cells/μl, suggesting the importance of expanded testing, early diagnosis and timely initiation of ART to improve the life expectancy of HIV-infected patients.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective:To evaluate the treatment strategies and outcomes for contracted nasal deformity.Methods:A retrospective review was conducted of the patients with contracted noses who underwent surgery at the Department of Plastic and Aesthetic Surgery, the Second Xiangya Hospital of Central South University, between January 2021 and January 2024. Based on the pathologic-anatomic features and severity of the deformity, patients were categorized as having mild, moderate or severe contraction. Mild cases received extensive subcutaneous dissection and framework reconstruction with various grafts. Moderate cases underwent preoperative nasal-skin distraction and intra-operative reconstruction with lower lateral or septal cartilage. Severe cases, in addition to reconstruction of the lower lateral cartilage and nasal septum, underwent individualized repair, including mucosal or cutaneous defect resurfacing. Postoperative follow-up assessed nasal appearance, complications and recurrence of contraction. Nasal aesthetics were quantified with visual analogue scale (VAS, 0-10 points; higher scores = less deformity), and patient satisfaction with the rhinoplasty outcome evaluation (ROE) questionnaire (0 = very dissatisfied, 100 = very satisfied) before surgery and at final follow-up. Paired t-test was used for VAS and ROE comparisons; categorical variables were analyzed with the χ2 test. A P-value < 0.05 denoted statistical significance. Results:A total of 96 patients were included, comprising 7 males and 89 females, aged (27.4 ± 8.0) years (19-58 years). There were 64 cases of mild, 19 cases of moderate, and 13 cases of severe contracted nose deformities. Postoperative follow-up(14.0 ± 4.6) months (6-19 months). No cases of abnormal nasal appearance, infection, necrosis, scar hyperplasia, or recurrence of contracted nose were observed during follow-up. Significant improvements in nasal aesthetic outcomes were observed. The VAS scores for mild, moderate, and severe contracted noses increased significantly from preoperative values of 4.7 ± 1.0, 3.0 ± 1.2, and 2.2± 1.1 to postoperative values of 8.6 ± 0.7, 8.9 ± 0.7, and 8.2 ± 0.9, respectively (all P < 0.01). Similarly, the ROE scores improved significantly from 59.1 ± 10.0, 34.2 ± 12.1, and 28.5± 6.3 preoperatively to 90.2 ± 9.5, 91.5 ± 7.5, and 93.3 ± 5.8 postoperatively (all P < 0.01). Conclusion:Selecting appropriate surgical methods based on the pathological and anatomical characteristics and severity of contracted nose deformities can achieve favorable outcomes. Postoperative nasal aesthetic appearance is significantly improved, and patient satisfaction is high.

Objective:To investigate the relationship between the severity of pharyngolaryngeal sensory impairment and swallowing biomechanics as well as the risk of penetration-aspiration in patients with dysphagia following infratentorial stroke.Methods:This retrospective cross-sectional study enrolled 51 patients with dysphagia following infratentorial stroke hospitalized in the Department of Rehabilitation Medicine of The Third Affiliated Hospital of Sun Yat-sen University between January 2022 and December 2023. Participants were categorized into three groups: normal sensation group [15 males, 2 females; age range 29-76 (56.0±13.3)years], diminished sensation group[16 males, 3 females; age range 38-80(62.0±11.8)years], and absent sensation group [14 males, 1 female; age range 44-75 (60.0±9.7)years]. All patients underwent laryngoscopy and videofluoroscopic swallowing study, which included pharyngolaryngeal sensory testing and Penetration-Aspiration Scale assessment. Swallowing temporal parameters were quantitatively analyzed. Group comparisons for different variable types were conducted using the Chi-square test, one-way ANOVA, and the Kruskal-Wallis test. The correlation between sensory groups and Penetration-Aspiration Scale scores was assessed using Spearman′s correlation analysis. Logistic regression was employed to analyze the impact of pharyngolaryngeal sensory function on penetration-aspiration events.Results:Among the 51 patients, 33.33% (17/51) had normal pharyngolaryngeal sensation, while, 66.67% (34/51) exhibited sensory impairment. The normal sensation group exhibited a significantly longer laryngeal vestibule closure (LVC) time [792 (643, 1 205) ms] compared to the diminished [528 (380, 776) ms] and absent sensation groups [380 (322, 404) ms] ( H=6.502, P=0.039). Additionally, the upper esophageal sphincter opening time was longer in the normal sensation group than in the absent sensation group [528 (371, 710) ms vs 182 (0, 710) ms, H=6.003, P=0.049]. Correlation analysis indicated a significant negative correlation between the severity of sensory impairment and Penetration-Aspiration Scale scores ( r=-0.366, P=0.008). Logistic regression analysis demonstrated that greater sensory impairment was an independent risk factor for penetration-aspiration ( OR=9.29, 95%CI=1.57-54.77, P=0.014). Conclusion:Pharyngolaryngeal sensory deficits are common after infratentorial stroke dysphagia and are significantly associated with impaired swallowing biomechanics and increased aspiration risk. The severity of sensory deficit is a key determinant of penetration-aspiration risk, highlighting its value in risk stratification and therapeutic decision-making for dysphagia.
