[Objective] To determine the correlation between traditional Chinese medicine (TCM) inspection of spirit classification and the severity grade of depression based on facial features, offering insights for intelligent intergrated TCM and western medicine diagnosis of depression. [Methods] Using the Audio-Visual Emotion Challenge and Workshop (AVEC 2014) public dataset on depression, which conclude 150 interview videos, the samples were classified according to the TCM inspection of spirit classification: Deshen (得神, presence of spirit), Shaoshen (少神, insufficiency of spirit), and Shenluan (神乱, confusion of spirit). Meanwhile, based on Beck Depression Inventory-II (BDI-II) score for the severity grade of depression, the samples were divided into minimal (0 – 13, Q1), mild (14 – 19, Q2), moderate (20 – 28, Q3), and severe (29 – 63, Q4). Sixty-eight landmarks were extracted with a ResNet-50 network, and the feature extracion mode was stadardized. Random forest and support vectior machine (SVM) classifiers were used to predict TCM inspection of spirit classification and the severity grade of depression, respectively. A Chi-square test and Apriori association rule mining were then applied to quantify and explore the relationships. [Results] The analysis revealed a statistically significant and moderately strong association between TCM spirit classification and the severity grade of depression, as confirmed by a Chi-square test (χ2 = 14.04, P = 0.029) with a Cramer’s V effect size of 0.243. Further exploration using association rule mining identified the most compelling rule: “moderate depression (Q3) → Shenluan”. This rule demonstrated a support level of 5%, indicating this specific co-occurrence was present in 5% of the cohort. Crucially, it achieved a high Confidence of 86%, meaning that among patients diagnosed with Q3, 86% exhibited the Shenluan pattern according to TCM assessment. The substantial Lift of 2.37 signifies that the observed likelihood of Shenluan manifesting in Q3 patients is 2.37 times higher than would be expected by chance if these states were independent—compelling evidence of a highly non-random association. Consequently, Shenluan emerges as a distinct and core TCM diagnostic manifestation strongly linked to Q3, forming a clinically significant phenotype within this patient subgroup. [Conclusion] Automated facial analysis can serve as a common lens for TCM and western psychological assessments align in the diagnosis of depression. The inspection of spirit decline trajectory parallels worsening depression, supporting early screening and stratified intervention, and providing a reference for the intelligent assistance of integrated TCM and western medicine in the diagnosis of depression.

OBJECTIVES: To investigate the ethnic origin of Chuanqing people, one of the largest unidentified ethnic groups in Guizhou, China, and analyze its genetic relationships with surrounding populations. METHODS: Based on a self-developed microhaplotype system, we conducted genotyping and analyzed the genetic distribution of microhaplotype loci and their forensic applicability in Chuanqing population in Guizhou Province. Using the microhaplotype data from different intercontinental populations and previously reported data from Han population living in Guizhou Province, we systematically investigated the genetic background of Chuanqing people through population genetic approaches, including genetic distance estimation, principal component analysis, and phylogenetic tree construction. RESULTS: Among the studied population, the number of haplotype per microhaplotype ranged from 6 to 25. The average expected heterozygosity (He), observed heterozygosity (Ho), power of discrimination (PD), and probability of exclusion (PE) were 0.8291, 0.8301, 0.9387, and 0.6593, respectively. The cumulative power of discrimination (CPD) and cumulative probability of exclusion (CPE) for these 33 loci were 1-2.62×10^-41 and 1-7.64×10^-17, respectively. Population genetic analyses revealed that the Chuanqing population had close genetic relationships with the East Asian populations, especially the local Guizhou Han population, Beijing Han population and the Han populations living in southern China. CONCLUSIONS The 33 microhaplotypes exhibit high levels of genetic diversity in the Guizhou Chuanqing population, highlighting their potentials for both forensic identification and parentage testing. The Han populations might have contributed a significant amount of genetic material to the Chuanqing population during the formation and development of the latter.

Objective:Exploratory study on the relationship between TCM syndrome types, TCM constitution and clinical symptoms of idiopathic central precocious puberty children and rapidly progressive early development children in Shanghai, so as to provide a basis for early intervention and syndrome differentiation and treatment.Methods:A cross-sectional study and retrospectively enrolled. Through questionnaire survey, the basic information, clinical symptoms and TCM constitution of children diagnosed with idiopathic central precocious puberty and rapidly progressive early development were collected from the Pediatric Endocrinology Clinic of Affiliated Shuguang Hospital of Shanghai University of Traditional Chinese Medicine from July to August 2022, and the correlation between the distribution, differentiation and clinical symptoms of TCM constitution in children with idiopathic central precocious puberty and children with rapidly progressive precocious puberty in Shanghai were explored through data analysis.Results:① Fast progressive early development children with higher BMI and age than idiopathic central precocious puberty were statistically significant ( P<0.05), and no significant difference in the sex composition ratio between the two groups. ② Among children with idiopathic central precocious puberty and children with rapid progressive early development, the proportion of liver depression fire syndrome was the highest, 59.15% (42/71) and 46.51% (60/129) respectively, and the proportion of Qi depression was the highest, 35.21% (25/71) and 36.43% (47/129) respectively. However, there was no significant difference in the TCM syndrome types and physical distribution of the two groups. ③ The TCM syndrome types of 200 precocious children weres correlated with physical distribution, among which Yin deficiency fire flourishing syndrome was significantly associated with Yin deficiency, liver stagnation fire syndrome was significantly correlated with qi depression, and phlegm dampness obstruction syndrome was significantly correlated with phlegm dampness and Yang deficiency ( P<0.01). ④ A total of 200 children with precocious puberty were more female than male, male BMI was higher than female, and the BMI of children with precocious puberty was higher than other syndrome types, and the differences were statistically significant ( P<0.01). Liver stasis fire syndrome was the highest proportion between boys and girls, but there was no obvious difference in TCM syndrome types between different genders. The highest proportion of breast pain in clinical symptoms was 22.19% (69/311). Conclusion:Children with idiopathic central precocious puberty and rapidly progressive early development children have differences in age and BMI, with no obvious difference in gender composition, TCM syndrome type and physical distribution, but there is a correlation between TCM syndrome type and physical constitution of precocious puberty children.

Objective To explore the value of blood inflammatory load in predicting overall survival of elderly patients with epithelial ovarian cancer(EOC).Methods Elderly patients with EOC were selected,and their clinical data and peripheral blood parameters were collected.We constructed an inflammation-related blood scoring system using univariate and multivariate Cox regression analysis.The Kaplan-Meier method was used for survival analysis.We used Cox proportional hazards analysis to identify the independent prognostic factors.A nomogram model was constructed based on independent prognostic factors,and the receiver operating characteristic curve,C-index,and calibration curve were used to evaluate the model.Results Patients with high blood inflammatory load had worse prognosis(P=0.002).Compared with the low inflammatory load group,patients with high inflammatory load had later clinical stages and larger ascites volume(P<0.05).Cox regression analysis showed that ACCI,CA125,residual lesions,and blood score were independent factors affecting overall survival(P<0.05).Conclusion The blood inflammatory load is the biomarker for the prognosis of elderly patients with EOC.Scoring the inflammatory load in the blood can assist in efficacy monitoring and treatment intervention of ovarian cancer patients.

[Objective] To investigate the correlation between human leukocyte antigen (HLA) gene polymorphism and hepatitis B virus (HBV) infection. [Methods] Venous blood samples were collected from 501 healthy individuals undergoing physical examinations at Yan’an Hospital in Kunming, Yunnan Province. Enzyme linked immunosorbent assay (ELISA) was used to detect HBV halves. Based on the results of HBV half detection, the patients were divided into three groups: HBV carrier group, previous infection group, and healthy control group. The HLA-A antigen genotype was detected using polymerase chain reaction with sequence specific primers (PCR-SSP) genotyping technology, and the distribution frequency of HLA-A gene polymorphism was compared between HBV carrier group and healthy control group, as well as between previous infection group and healthy control group. SPSS17.0 software was used for data statistical analysis. [Results] In the healthy control group, the HLA-A2 positivity rate was 47.49%, and the allele frequency was 31.29%.The overall frequency of gene distribution in the healthy control group was consistent with the HLA-A allele table commonly and confirmed in China published by the Chinese Bone Marrow Bank. The HLA-A2 positivity rate and allele frequency in the HBV carrier group were 63.04% and 42.23%, respectively; The difference in HLA-A2 positivity rate and allele frequency among carriers was statistically significant (P<0.05). the HLA-A2 positivity rate and allele frequency in the HBV previous infection group were 56.14% and 35.97%, respectively, which did not significantly differ from those in the healthy control group (P>0.05). [Conclusion] HLA-A2 gene may be a susceptibility gene for chronic hepatitis B HBV carriers.

Objective To explore the correlation of serum level of reduced NOX2 with cerebral blood supply and prognosis in elderly patients with TBI.Methods A total of 86 elderly TBI pa-tients admitted to our department from January 2019 to December 2022 were recruited and served as the TBI group,and another 80 age-and gender-matched elderly individuals who took physical examinees in our hospital during the same period were enrolled and served as the control group.According to the GCS score at admission,the TBI group was divided into mild,moderate and se-vere subgroups(22,35 and 29 cases).The patients were also assigned into good prognosis sub-group(54 cases)and poor prognosis subgroup(32 cases)based on GOS score in 6 months after treatment.The dynamic changes in serum NOX2 level and cerebral blood flow indicators among different groups and subgroups were compared,and their correlation with the prognostic GOS score was analyzed.Results The average blood flow Vm,rCBF,and rCBV of TBI patients at 1,3,5,7,and 10 d after injury were significantly reduced,and the serum NOX2 level was obviously in-creased when compared to the control group(P＜0.01).Statistical difference was seen in serum NOX2 level among the patients with different degrees of TBI at 1,3,5,7 and 10 d after injury(P＜0.05,P＜0.01).The serum NOX2 level at 1,3,5,7,10 and 14 d after injury in the TBI group was negatively correlated with GCS score(r=-0.413,-0.427,-0.515,-0.592,-0.566,-0.338;P＜0.01),and the Vm CBV,and rCBF values at 1,3,5,7,and 10 d after injury were posi-tively correlated with GCS score(r=0.392,0.379,0.407,0.418,0.420,P＜0.01;r=0.404,0.414,0.429,0.419,0.428,P＜0.01;r=0.412,0.427,0.432,0.428,0.393,P＜0.01).The serum NOX2 level at 1,3,5,7 and 10 d after injury in the TBI group was negatively correlated with Vm,rCBV and rCBF values(P＜0.01).The serum NOX2 level of the patients in the poor prognosis subgroup were significantly higher than those in the good prognosis subgroup at 1,3,5,7,10,and 14 d after injury,while,the rCBV and rCBF values were obviously lower than those in the good prognosis subgroup(P＜0.05,P＜0.01).The serum NOX2 level in the TBI patients at 1,3,5,7,10,and 14 d after injury were negatively,while Vm,rCBV and rCBF values were positively correlated with GOS scores at 6 months after treatment(P＜0.01).Conclusion Elevated serum NOX2 level is closely correlated with insufficient cerebral blood supply and poor prognosis in elderly TBI pa-tients.Dynamic monitoring of serum NOX2 level and changes in cerebral blood flow indicators are of great clinical significance in evaluation of TBI prognosis.

Objective:To investigate the risk factors for bleeding and thrombosis during extracorporeal membrane oxygenation (ECMO) therapy in critically ill patients and determine the best predictors of coagulation-related complications.Methods:A retrospective analysis was performed on patients who received ECMO for respiratory or circulatory failure at Xiangya Hospital of Central South University from January 2020 to December 2022. The outcome was whether bleeding or thrombosis occurred from 24 h after ECMO insertion to before weaning. The differences in demographic characteristics, weaning conditions, prognosis, routine blood tests, organ function, coagulation and blood product transfusion of each group were compared. Logistic regression analysis was used to evaluate the risk factors for bleeding and thrombosis, and ROC curve evaluation was used to assess their capacity to predict complications.Results:A total of 61 patients with ECMO were enrolled, with 21 cases of bleeding and 14 cases of thrombosis during ECMO. Compared with the nonbleeding group, the activated partial thromboplastin time, thromboplastin time (TT), and transfusions of frozen plasma and red blood cells were higher in the bleeding group (all P<0.05). Compared with the nonthrombotic group, the increase in body weight, D-dimer (DD), fibrinogen degradation product (FDP), and improvement of arterial oxygen partial pressure (ΔPO 2) within 24 h were significantly higher in the thrombotic group (all P<0.05). Logistic regression analysis revealed that TT ( OR=1.039, 95% CI: 1.006~1.072, P=0.018) and frozen plasma transfusion volume ( OR=1.046, 95% CI: 1.010-1.083, P=0.012) were risk factors for bleeding events. FDP ( OR=1.030, 95% CI: 1.009-1.051, P=0.005), DD ( OR=1.181, 95% CI: 1.044-1.336, P=0.008), and ΔPO 2 ( OR=1.007, 95% CI: 1.002-1.012, P=0.006) were risk factors for thrombosis. According to ROC curve analysis, the AUCs of TT, frozen plasma transfusion, and combined indexes for predicting bleeding were 0.712, 0.690, and 0.816, respectively. The combined indices had a cut-off value of 0.273, a sensitivity of 75.61%, and a specificity of 80.00%. The AUCs of FDP, DD, ΔPO 2, and combined FDP with ΔPO 2 for predicting thrombosis were 0.778, 0.748, 0.786, and 0.868, respectively. The cut-off value of the combined index was 0.157, the sensitivity was 68.09%, and the specificity was 92.86%. Conclusions:TT combined with frozen plasma transfusion volume predicted bleeding optimally, while FDP plus ΔPO 2 predicted thrombotic events better during ECMO treatment in critically ill patients.

Objective:To establish a three-dimensional model of locking plate fixation for 42A2 type oblique tibial fractures with different fracture line directions and different angles between the fracture line and the long axis of the tibia. Finite element analysis was used to calculate and analyze the biomechanics of locking plate, screw, and tibia, providing theoretical basis for clinical application.Methods:A healthy adult volunteer, 25 years old, male, with a height of 173 cm and a weight of 69.5 kg, was selected to perform computed tomography (CT) scans on the left tibia. Relevant data were obtained to establish a locking steel plate fixation model for 42A2 type tibia with different oblique fracture line directions and different angles between the fracture line and the long axis of the tibia. Eight hole pure titanium plates were used for fixation, respectively. We compared the Mises stress changes of locking plates, screws, and tibia in different angle fracture models.Results:In the case of a 42A2 type fracture in the left oblique direction with a fracture line from outside to inside, the maximum Mises stress in the tibia was 114 MPa, the maximum Mises stress in the screw was 279.8 MPa, and the maximum Mises stress in the locking steel plate was 302.4 MPa; In the case of a 42A2 type fracture in the right oblique fracture with a fracture line from the bottom to the top, the maximum Mises stress of the tibia was 93.41MPa, the maximum Mises stress of the screw was 353.4 MPa, and the maximum Mises stress of the locking steel plate was 411.8 MPa.Conclusions:Regardless of the oblique fractures in both left and right directions, the maximum stress values are: locking plate>screw>tibia; When the position of the locking steel plate is fixed, the maximum stress values of the locking steel plate and screw are both right oblique fracture>left oblique fracture; And the maximum stress values all increase with the increase of angle.

Objective:To investigate the mechanism of levosimendan on acute kidney injury after cardiopulmonary resuscitation (CPR) in rats.Methods:Twenty-five healthy adult male SD rats were randomly divided into three groups: control group ( n=5), levosimendan group ( n=10) and experimental group ( n=10). A cardiac arrest-cardiopulmonary resuscitation model was established using smothering method in the experimental group and levosimendan group. The levosimendan group was treated with levosimandan during and after resuscitation, while the experimental group was given equivalent volume of saline solution during and after resuscitation, and the control group was only given equivalent volume of saline without performance of CPR. The rats in the three groups were sacrificed at 6 h after resuscitation. The serum and kidney tissue samples were collected. Serum biochemical indicators [serum creatinine (Scr), blood urea nitrogen (Bun), interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α)] were measured. HE staining and Paller score were used to identify the degree of kidney damage. Apoptosis was estimated by TUNEL staining. Western blot was used to detect the expression levels of phosphorylation of extracellular regulated protein kinases (p-ERK). One-way analysis of variance was used to compare the mean values of normally distributed measurement data between groups. Comparisons between groups were performed using the least significant difference t-test. Results:Scr (85.02±1.31) μmol/L, Bun (7.36±0.13) mmol/L, Paller score (7.3±0.2), IL-1β (302.20±17.35) pg/mL, IL-6 (564.60±23.24) pg/mL and TNF-α (1346±83.73) pg/mL in the experimental group were significantly higher than those of the control group [(15.94±0.96) μmol/L, (2.95±0.18) mmol/L, (0.7±0.2), (7.27±0.44) pg/mL, (51.30±2.87) pg/mL, and (10.39±0.52) pg/mL] (all P<0.01). Compared with the experimental group, Scr (63.88±2.01) μmol/L, Bun (5.45±0.47) mmol/L, paller score (4.8±0.2), IL-1β (78.61±3.66) pg/mL, IL-6 (297.90±13.64) pg/mL and TNF-α (276.2±20.18) pg/mL were significantly decreased in the levosimendan group (all P<0.01). TUNEL staining showed that levosimendan could improve the apoptosis of renal cells ( P<0.01). The expression of p-ERK protein in the levosimendan group was significantly higher than that in the experimental group ( P<0.01). Conclusions:Lovosimendan could attenuate acute kidney injury following cardiac arrest and cardiopulmonary resuscitation via suppression apoptosis. The mechanism of levosimendan protective effect might be associated with activation of ERK signaling pathway.

Objective:To analyze the prognostic factors of Krukenberg tumors derived from the gastric cancer and colorectal cancer, so as to guide comprehensive treatment; looking for objective and sensitive indicators of ovarian metastasis during the follow-up after the surgery for gastric and colorectal cancer, which provides a basis for early diagnosis.Methods:Retrospectively analyzed the clinical data of 75 patients diagnosed with Krukenberg tumor admitted to Beijing Friendship Hospital, Capital Medical University from June 2007 to February 2020. Log-rank method and COX regression analysis were used to find independent prognostic factors. Wilcoxon rank sum test was used to compare the dynamic changes of ovarian imaging and tumor markers and to find the more sensitive indicators in the follow-up of patients with metachronous metastasis.Results:In the 75 cases, the univariate analysis suggested that CA19-9≥123.5 U/mL ( P=0.001), CA12-5≥37.9 U/mL ( P=0.018), Krukenberg tumor of stomach origin ( P=0.037), extra-ovary metastasis ( P=0.014), and without cytoreductive surgery (CRS) ( P<0.001)were poor prognostic factors. Among them, cytoreductive surgery could significantly improve the prognosis, even if with visible residual lesions, the overall survival was still significantly longer than those who have not undergone cytoreductive surgery ( P=0.004). Multivariate analysis results showed that CA19-9 and cytoreductive surgery ( P=0.001) were independent prognostic factors for patients with Krukenberg tumor; during the postoperative follow-up, ultrasound and CT imaging changes were more sensitive to ovarian metastasis ( P=0.006). Conclusions:CRS can prolong significantly the overall survival (OS) of patients with krukenberg tumor. Patients with simultaneous metastases should not give up the opportunity for surgery, and patients with metachronous metastases should also receive ovary resection procedure, even if with visible residual lesions, the patients can still benefit from the procedure. In the follow-up for gastric and colorectal cancer, attention should be paid to the ovarian ultrasound and CT imaging changes to facilitate early detection of ovarian metastases.
