Objective:
To fabricate a hydrogel loaded with inositol hexaphosphate-zinc and preliminarily evaluate its performance in self-mineralization and osteoinduction, thereby providing a theoretical basis for the development of bone regeneration materials.
Methods:
The hydrogel framework (designated DF0) was formed by copolymerizing methacryloyloxyethyltrimethylammonium chloride and four-armed poly(ethylene glycol) acrylate, followed by sequentially loading inositol hexaphosphate anions via electrostatic interaction and zinc ions via chelation. The hydrogel loaded only with inositol hexaphosphate anions was named DF1, while the co-loaded hydrogel was named DF2. The self-mineralization efficacy of the DF0 , DF1 and DF2 hydrogels was characterized using scanning electron microscopy, transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), and selected area electron diffraction (SAED). The biocompatibility was assessed via live/dead cell staining and a CCK-8 assay. The osteoinductive capacity of the DF0 , DF1 and DF2 hydrogels on MC3T3-E1 cells was assessed via alkaline phosphatase (ALP) and Alizarin Red S (ARS) staining. In the aforementioned cell experiments, cells cultured in standard medium served as the control group
Results:
The DF0, DF1, and DF2 hydrogels were successfully synthesized. Notably, DF1 and DF2 exhibited distinct self-mineralization within 6 days. Results from TEM, EDS, and SAED confirmed that the mineralization products were amorphous calcium phosphate in group DF1, and amorphous calciumzinc phosphate in group DF2. Biocompatibility tests revealed that none of the hydrogels (DF0, DF1, and DF2) adversely affected cell viability or proliferation. In osteogenic induction experiments, both ALP and ARS staining were intensified in the DF1 and DF2 groups, with the most profound staining observed in the DF2 group.
Conclusion
The developed inositol hexaphosphate-zinc hydrogel (DF2) demonstrates the dual capacity to generate calcium-phosphate compounds through self-mineralization while exhibiting excellent osteoinductive properties. This biocompatible, dual-promoting osteogenic hydrogel presents a novel strategy for bone regeneration.

Objective:
To develop a depression recognition model by integrating the spirit-expression diagnostic framework of traditional Chinese medicine (TCM) with machine learning algorithms. The proposed model seeks to establish a TCM-informed tool for early depression screening, thereby bridging traditional diagnostic principles with modern computational approaches.
Methods:
The study included patients with depression who visited the Shanghai Pudong New Area Mental Health Center from October 1, 2022 to October 1, 2023, as well as students and teachers from Shanghai University of Traditional Chinese Medicine during the same period as the healthy control group. Videos of 3 – 10 s were captured using a Xiaomi Pad 5, and the TCM spirit and expressions were determined by TCM experts (at least 3 out of 5 experts agreed to determine the category of TCM spirit and expressions). Basic information, facial images, and interview information were collected through a portable TCM intelligent analysis and diagnosis device, and facial diagnosis features were extracted using the Open CV computer vision library technology. Statistical analysis methods such as parametric and non-parametric tests were used to analyze the baseline data, TCM spirit and expression features, and facial diagnosis feature parameters of the two groups, to compare the differences in TCM spirit and expression and facial features. Five machine learning algorithms, including extreme gradient boosting (XGBoost), decision tree (DT), Bernoulli naive Bayes (BernoulliNB), support vector machine (SVM), and k-nearest neighbor (KNN) classification, were used to construct a depression recognition model based on the fusion of TCM spirit and expression features. The performance of the model was evaluated using metrics such as accuracy, precision, and the area under the receiver operating characteristic (ROC) curve (AUC). The model results were explained using the Shapley Additive exPlanations (SHAP).
Results:
A total of 93 depression patients and 87 healthy individuals were ultimately included in this study. There was no statistically significant difference in the baseline characteristics between the two groups (P > 0.05). The differences in the characteristics of the spirit and expressions in TCM and facial features between the two groups were shown as follows. (i) Quantispirit facial analysis revealed that depression patients exhibited significantly reduced facial spirit and luminance compared with healthy controls (P < 0.05), with characteristic features such as sad expressions, facial erythema, and changes in the lip color ranging from erythematous to cyanotic. (ii) Depressed patients exhibited significantly lower values in facial complexion L, lip L, and a values, and gloss index, but higher values in facial complexion a and b, lip b, low gloss index, and matte index (all P < 0.05). (iii) The results of multiple models show that the XGBoost-based depression recognition model, integrating the TCM “spirit-expression” diagnostic framework, achieved an accuracy of 98.61% and significantly outperformed four benchmark algorithms—DT, BernoulliNB, SVM, and KNN (P < 0.01). (iv) The SHAP visualization results show that in the recognition model constructed by the XGBoost algorithm, the complexion b value, categories of facial spirit, high gloss index, low gloss index, categories of facial expression and texture features have significant contribution to the model.
Conclusion
This study demonstrates that integrating TCM spirit-expression diagnostic features with machine learning enables the construction of a high-precision depression detection model, offering a novel paradigm for objective depression diagnosis.

ObjectiveTo explore the listed varieties and prescription characteristics of Chinese patent medicines for stroke in China, explore the medication rules of Chinese medicine for stroke, and provide guidance for further clinical research and development of Chinese patent medicines. MethodsExcel 2021 and the Ancient and Modern Medical Record Cloud Platform (V2.3.5) were used to systematically mine and analyze the varieties and prescriptions of Chinese patent medicines for stroke in China. ResultsA total of 244 Chinese patent medicines (two for different dosage forms of the same prescription), 1 736 approval documents for Chinese patent medicines, 792 manufacturers, and 83 varieties of protected Chinese patent medicines were finally included in the database. The top three dosage forms were capsules (75), pills (53), and tablets (42). There were 28 Chinese patent medicines for stroke in the National Essential Drug Catalogue (2018), 129 in the National Essential Medical Insurance, Industrial Injury Insurance and Maternity Insurance Drug Catalogue (2023), and 4 in the National Non-prescription Drug Catalogue. Among the 138 prescriptions screened out, Chinese patent medicines mainly treated stroke patients with the syndrome of Qi deficiency and blood stasis. The top three most frequent medicinal herbs were Chuanxiong Rhizoma (63), Pheretima (47), and Salviae Miltiorrhizae Radix et Rhizoma (47). The medicinal herbs used were mainly warm, pungent, with the meridian tropism to the liver meridian. The correlation analysis showed that the herb pair with the highest support was Astragali Radix-Chuanxiong Rhizoma, and that with the highest confidence was Carthami Flos-Chuanxiong Rhizoma. Five herb combinations were identified based on the cluster analysis. ConclusionThe Chinese patent medicines for stroke mainly treat patients with the syndrome of Qi deficiency and blood stasis. The medicinal herbs used in the prescriptions mainly have the functions of activating blood and resolving stasis, extinguishing wind and stopping convulsions. Drug compatibility usually focuses on activating blood and resolving stasis, as well as expelling phlegm and opening orifices. This review of the varieties and prescription characteristics of Chinese patent medicines for stroke helps optimize clinical decision-making, guide drug research and development, promote medical research and scientific progress, and provide more effective support and guarantee for the treatment of stroke patients.

Objective To explore the technical process and clinical application of laparoscopic combined upper midline incision minimally invasive liver transplantation. Methods A retrospective analysis was conducted on 30 cases of laparoscopic combined upper midline incision minimally invasive liver transplantation. The cases were divided into cirrhosis group (15 cases) and liver failure group (15 cases) based on the primary disease. The surgical and postoperative conditions of the two groups were compared. Results All patients successfully underwent laparoscopic "clockwise" liver resection, with no cases of passive conversion to open surgery or intolerance to pneumoperitoneum. In 6 cases, the right lobe was relatively large, and the right hepatic ligaments could not be completely mobilized. One case required an additional reverse "L" incision during open surgery. All patients successfully completed the liver transplantation, with no major intraoperative bleeding, cardiovascular events, or other occurrences in the 30 patients. The model for end-stage liver disease (MELD) score in the cirrhosis group was lower than that in the liver failure group (P<0.001). There were no statistically significant differences between the two groups in terms of age, surgical time, blood loss, anhepatic phase, or cold ischemia time (all P>0.05). During the perioperative period, there was 1 case of hepatic artery embolism, 1 case of portal vein anastomotic stenosis, no complications of hepatic vein and inferior vena cava, and 3 cases of biliary anastomotic stenosis, all of which occurred in the liver failure group. Conclusions In strictly selected cases, the minimally invasive liver transplantation technique combining laparoscopic hepatectomy with upper midline incision for graft implantation has the advantages of smaller incisions, less bleeding, relatively easier operation, and faster postoperative recovery, which is worthy of clinical promotion and application.

Chinese Journal of School Health 2025;46(1):53-57
Objective:
To explore the current status and influencing factors of eating behaviors in adolescents, so as to provide a theoretical foundation for health promotion education among adolescents.
Methods:
Based on the database from Survey of Chinese Family Health Index (2021), by a random number table method, 1 065 teenagers were selected from the provincial capitals of 22 provinces and 5 autonomous regions in China, as well as 4 municipalities directly under the central government. A general characteristic questionnaire, Patient Health Questionnaire-9 (PHQ-9), Short Form of the Family Health Scale (FHS-SF), 10-item Short Version of the Big Five Personality(BFP-10), Content-based Media Exposure Scale (CM-E) and Sakata Eating Behavior Scale Short Form(EBS-SF) were used to collect information. Multivariate stepwise linear regression analysis was employed to identify and analyze related factors of eating behaviors among adolescents. Receiver operating characteristic was used to validate the predictive ability of the EBS-SF score for overweight and obesity among adolescents.
Results:
The average scores of BFI-10,C-ME, FHS-SF, PHQ-9 and EBS-SF were (33.08±4.64)(19.20±4.55)(38.48±6.65)(6.09±5.63)(16.75±4.36), respectively. Multivariate linear regression showed that family type (other types), agreeableness, conscientiousness, family health and depression were the main related factors of EBS-SF scores among adolescents( B =2.61,-0.42,0.20,-0.11,0.23, P <0.05).The analysis of receiver operating characteristic curve showed that the EBS-SF scores had a good ability in predicting obesity among male adolescents ( AUC= 0.73, P <0.01).
Conclusions
Family type, big five personality, family health,depression are the related factors of eating behaviors among adolescents. EBS-SF scores are predictive of obesity in adolescents, which would provide a new perspective for promoting healthy eating habits among adolescents.

ObjectiveTo explore the effects of different dosage forms of Kaixinsan (KXS) on the morphology and function of mitochondria in rat models of Alzheimer's disease (AD) and potential mechanisms of action. MethodsMale SD rats were randomly assigned to a sham group, model group, treatment groups receiving KXS decoction, powders, and granules (3.08 g·kg-1), as well as donepezil group (0.51×10-3 g·kg-1), with 10 rats in each group. AD model was created using intracerebroventricular injection of streptozocin (STZ). After 30 days of administration, behavioral assessments were conducted, and mitochondrial morphology was observed using transmission electron microscopy. Mitochondrial respiratory chain complex content was measured via enzyme-linked immunosorbent assay (ELISA). Changes in mitochondrial membrane potential were measured via JC-1 staining, and superoxide dismutase (SOD) activity and reactive oxygen species (ROS) levels were measured via biochemical assays. The mRNA expression of adenosine 5'-monophosphate-activated protein kinase (AMPK), peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α), and silent information regulator 3 (SIRT3) was detected by real-time fluorescent quantitative polymerase chain reaction (Real-time PCR), and Western blot was used to examine the protein expression levels of optic atrophy protein1 (OPA1), mitochondrial fission protein 1 (FIS1), AMPK, p-AMPK, PGC-1α, and SIRT3. ResultsCompared with the sham group, rats in the model group had significantly lower recognition index, spontaneous alternation rate, escape latency, number of platform crossings, time spent in the target quadrant, and percentage of distance traveled in the target quadrant distance (P<0.05, P<0.01). Significant mitochondrial damage was observed in the hippocampal tissue, with a marked decrease in mitochondrial respiratory chain complex content (P<0.01) and reduced mitochondrial membrane potential (P<0.05). Additionally, the SOD activity was reduced, while ROS levels were elevated (P<0.01). The mRNA expression of PGC-1α and SIRT3 was significantly downregulated (P<0.01), along with decreased protein expression levels of OPA1, p-AMPK/AMPK, PGC-1α, and SIRT3, whereas FIS1 protein expression was significantly upregulated (P<0.05, P<0.01). Compared with the model group, rats in KXS-treated groups (various dosage forms) showed significant improvement in behavioral indexes (P<0.05, P<0.01), reduced hippocampal mitochondrial damage, and more organized mitochondrial cristae. Mitochondrial respiratory chain complex content was significantly increased (P<0.05, P<0.01), and mitochondrial membrane potentials were elevated (P<0.05). SOD activity was elevated, and ROS levels were significantly reduced (P<0.05, P<0.01). Furthermore, the mRNA expression of PGC-1α and SIRT3 was upregulated, with increased protein levels of OPA1, p-AMPK/AMPK, PGC-1α, and SIRT3, while FIS1 protein expression levels were significantly reduced (P<0.05, P<0.01). Across the KXS-treated groups, the granule group showed a higher spontaneous alternation rate than the decoction and powder groups (P<0.05). ConclusionKXS decoction, powders, and granules can improve the learning and memory ability of rats, with granules being the most effective. The mechanism of action may involve activation of the AMPK/PGC-1α/SIRT3 signaling pathway, improvement of the mitochondrial function, and subsequent amelioration of the brain energy metabolism disorders.

ObjectiveTo investigate the prevalence rate of chronic non-communicable diseases (NCDs) and the association with quality of life in middle-aged and elderly patients with HIV/AIDS. MethodsThis cross-sectional study surveyed 432 patients with HIV/AIDS (aged≥45 years) in the Infectious Disease Center in Guangzhou Eighth People’s Hospital of Guangzhou Medical University, and 366 participants were included in the analysis after quality control. A questionnaire and the EuroQol 5-Dimensional 3-level version (EQ-5D-3L) were used to investigate NCDs and quality of life and Tobit regression model was used to estimate the association between chronic diseases and quality of life. ResultsAmong the 366 participants, 29(7.9%) had cardiovascular disease, 45(12.3%) had hypertension, 122(33.3%) had hyperglycemia, 151(41.3%)had hyperlipidemia,7(1.9%) had cancer, 17 (4.6%) had chronic kidney disease, 38 (10.4%) had chronic liver disease, 21(5.7%) had musculoskeletal disorders, and 253(69.1%) suffered from at least one type of chronic diseases. The median (lower and upper quartiles) of EQ-5D utility index was 1.000(0.964~1.000). Multivariate Tobit regression results of the total population showed that cancer [ba=-0.08,95%CI (-0.15,-0.01),P=0.036], chronic kidney disease [ba=-0.07, 95%CI (-0.12,-0.02),P=0.006], musculoskeletal disease [ba=-0.09, 95%CI (-0.13, -0.05),P<0.001], and ≥3 types of chronic diseases[ba=-0.05, 95%CI(-0.08,-0.01),P=0.013] were negatively correlated with EQ-5D utility index. The stratified analysis results of different CD4+T cell levels showed that hypertension [ba=-0.07, 95%CI (-0.12, -0.02), P=0.007], chronic kidney disease [ba=-0.10,95%CI (-0.18,-0.03), P=0.006], musculoskeletal disease [ba=-0.15, 95%CI (-0.22,-0.07), P<0.001] and ≥3 types of chronic diseases [ba=-0.09, 95%CI (-0.09, -0.01), P<0.001] were negatively correlated with EQ-5D utility index in the group with CD4≤500 (cells/μL), whereas cancer[ba=-0.11, 95%CI (-0.20,-0.01), P=0.031] was negatively correlated with EQ-5D utility index in the group with CD4>500(cells/μL). ConclusionsThe prevalence rate of chronic non-communicable diseases in middle-aged and elderly patients with HIV/AIDS is relatively high. The classification of NCDs such as cancer or chronic kidney disease or other chronic diseases and the numbers of NCDs categories are negatively correlated with quality of life. However,this association varies among patients with HIV/AIDS of different CD4+T cell levels. It is suggested that we should try to prevent and identify NCDs at an early stage, strengthen linkages and integration of health services for AIDS and chronic NCDs, and jointly manage and control AIDS with chronic diseases to improve the quality of life among people living with HIV/AIDS.

The study explores the traditional Chinese medicine (TCM) diagnostic and treatment approach to coronary microvascular disease (CMVD) from the perspective of "disharmony of blood collaterals and dysfunction of qi transformation". It is proposed that the core pathogenesis of CMVD lies in these two mechanisms. From an integrative medicine perspective, different CMVD types are analyzed based on their specific pathogenesis. Through clinical practice, four targeted treatment methods, i.e. warming, unblocking, tonifying, and activating, are formulated. CMVD caused by atherosclerosis is primarily associated with myocardial ischemia, myocardial infarction, and coronary revascularization, with corresponding pathological mechanisms of latent pathogenic obstruction, toxic accumulation in the collaterals, and deficiency with collateral stasis. The disease progression exhibits characteristics of correlation, staging, and transformation. Accordingly, treatment principles include warming to assist qi transformation, unblocking obstruction and dispelling turbidity, activating to disperse toxic stasis and invigorate collaterals, and tonifying to eliminate stasis and nourish collaterals. For CMVD unrelated to atherosclerosis, attention should be paid to the underlying disease, analyzing the main syndromes of blood and collateral disharmony. An approach combining disease-syndrome differentiation with blood and collateral regulation is emphasized for precise treatment.
