BackgroundMental health issues have become increasingly prominent amid rising societal pressure. Depressive disorders， characterized as chronic and recurrent conditions， adversely affect patients' physical and mental well-being while imposing a significant economic burden. Previous studies on depressive disorders in China have relied on cross-sectional surveys， capturing prevalence at specific time points， but lacking systematic analyses across age， period， and cohort dimensions. ObjectiveTo analyze long-term trends in the disease burden of depressive disorder in the Chinese population from 1990 to 2021， and to provide references to inform prevention and treatment strategies. MethodsData on the disease burden of depressive disorders in China were obtained from the Global Burden of Disease Study 2021 （GBD 2021） database. A joinpoint regression model was used to analyze trends in the disease burden. An age-period-cohort model， implemented in Stata 17.0， was applied to assess variations in incidence and disease burden attributable to age， period and cohort effects. ResultsFrom 1990 to 2021， the disability-adjusted life year （DALY） rate for depressive disorders in China decreased by an average of 0.27% annually， while the incidence rate decreased by an average of 0.24% annually. Females had higher incidence and DALY rates than those of males. The age-period-cohort model analysis revealed that age effects on incidence and disease burden steadily increased， period effects declined over time， and cohort effects initially increased and then declined. ConclusionFrom 1990 to 2021， both the incidence and DALY rates of depressive disorders in China showed a declining trend. Females experienced a higher burden compare to males. Additionally， incidence and DALY rates increased with age but declined over time.

The results of methodological investigation for the determination of seven active components in fifteen batches of samples all met the requirements. Conclusion The established characteristic atlas of Shexiang Jiegu Capsules had high specificity and good repeatability, which could provide scientific basis for quality control of Shexiang Jiegu Capsules.

ObjectiveTo evaluate the clinical efficacy of Huayu Tongluo Formula （化瘀通络方， HTF） in patients with mid-stage diabetic kidney disease of blood stasis syndrome and explore its potential mechanisms. MethodsA multi-center， randomized， double-blind， placebo-controlled clinical trial was conducted. Ninety patients of mid-stage diabetic kidney disease of blood stasis syndrome were divided into a control group of 46 cases and a treatment group of 44 cases. Both groups received conventional western medicine treatment， the treatment group additionally taking HTF， while the control group taking a placebo of the formula. The treatment was administered once daily for 24 weeks. The primary outcomes included 24-hour urine total protein （24 h-UTP）， serum albumin （Alb）， glycated hemoglobin （HbA1c）， and serum creatinine （Scr）.The secondary outcomes included changes in levels of endothelin-1 （ET-1）， nitric oxide （NO）， vascular endothelial growth factor （VEGF）， and traditional Chinese medicine （TCM） syndrome scores before and after treatment. Clinical efficacy was evaluated based on TCM syndrome scores and overall disease outcomes. Adverse reactions and endpoint events were recorded. ResultsIn the treatment group after treatment， 24 h-UTP， ET-1， and VEGF levels significantly decreased （P＜0.05）， Alb and NO levels significantly increased （P＜0.05）； while the TCM syndrome scores for edema， lumbar pain， numbness of limbs， dark purple lips， dark purple tongue or purpura， and thin， rough pulse all significantly decreased （P＜0.05）. In the control group， no significant changes were observed in any of the indicators after treatment （P＞0.05）.Compared with the control group， the treatment group showed significant reductions in 24 h-UTP， ET-1， and VEGF levels， and increases in Alb and NO levels （P＜0.05）. The TCM syndrome scores for edema， lumbar pain， dark purple tongue or purpura， and thin， rough pulse were all lower in the treatment group than in the control group （P＜0.05）. The total effective rate of TCM syndrome in the treatment group was 59.09% （26/44）， and the overall clinical effective rate was 45.45% （20/44）. In the control group， these rates were 15.22% （7/46） and 8.7% （4/46）， respectively， with the treatment group showing significantly better outcomes （P＜0.05）. A total of 7 adverse events occurred across both groups， with no significant difference （P＞0.05）. No endpoint events occurred during the study. ConclusionOn the basis of conventional treatment of Western medicine， HTF can further reduce urinary protein levels and improve clinical symptoms in patients with mid-stage diabetic kidney disease of blood stasis syndrome. The mechanism may be related to its effects on endothelial function.

Colorectal cancer is a common and malignant tumor in the digestive tract. Invasion and metastasis of cancer cells are key factors leading to the high mortality rate and postoperative recurrence of colorectal cancer. Chemotherapy is the main treatment method for preventing recurrence of this disease. However， there are many toxic side effects in clinical application， which seriously hinder the treatment process. Therefore， it is imperative to search for efficient and low-toxicity drugs. Traditional Chinese medicine （TCM） has a long history of treating colorectal cancer and offers advantages such as safety， effectiveness， multiple targets， multiple pathways and minimal toxic side effects， which have made it increasingly popular worldwide. According to TCM， the pathogenesis of colorectal cancer is rooted in both deficiency and excess. TCM formulas mainly focus on tonifying the body to address the invasion and metastasis of colorectal cancer， such as Jianpi compound， Jianpi Xiaoai decoction， and Bushen Jiedu Sanjie decoction. TCM monomers， such as emodin， berberine， and tanshinone， mainly focus on clearing heat and removing toxin， circulating blood and transforming stasis， and resolving swelling and dispersing nodules. Signaling pathways play a crucial role for analyzing invasion and metastasis， and research has shown that pathways such as Wnt/β-catenin， phosphatidylinositol-3 kinase/protein kinase （PI3K/Akt）， Janus kinase 2/signal transduction and transcription activating factor 3 （JAK2/STAT3）， nuclear factors-κB （NF-κB）， vascular endothelial growth factor （VEGF） play important roles in the invasion and metastasis of colorectal cancer. The invasion and metastasis of colorectal cancer can be inhibited via regulating the key proteins and related factors in these pathways. In this review， we searched various literature databases， such as PubMed， China National Knowledge Infrastructure （CNKI）， and VIP， using keywords such as "colorectal cancer"， "signaling pathway"， "invasion and metastasis"， and "traditional Chinese medicine"， to summarize and analyze the relevant pathways of TCM compounds and monomers against invasion and metastasis of colorectal cancer published in the past five years. The review aims to provide new insights and references for in-depth research on the therapy for invasion and metastasis of colorectal cancer and new drug development.

The human oral microbiota includes over 700 microorganisms such as fungi, bacteria, archaebacteria, and viruses. The interaction between fungi and bacteria, as well as their impact on the host immune system, is currently a popular topic in the field of oral disease research. Porphyromonas gingivalis (P.g) is the key pathogenic bacterium of chronic periodontitis, while Candida albicans (C.a) is a common opportunistic pathogen. P.g and C.a are associated with various oral diseases. A review of the literature suggests that P.g and C.a synergistically increase the amount of biofilm. They adhere to each other, promoting the formation of mixed biofilms. At the same time, C.a can utilize its dense hyphae and metabolic activities to consume oxygen, providing a low-oxygen microenvironment for P.g, thereby enhancing its vitality and virulence. C.a and P.g can also enhance their virulence through heme competition mechanisms and maintain the normal morphology of P.g by extracellular polysaccharides. In addition, P.g and C.a can synergistically invade the host and escape from the host’s immune system, ultimately leading to a state of chronic infection in the host. Based on the interactions of P.g and C.a, numerous studies on prevention and treatment strategies have been conducted, including those of various composite materials and natural plants. However, such drugs are mostly limited to phenotypes and suffer from poor selectivity, thus resulting in a lack of specific drugs and research on their mechanisms. This review aims to explore the latest advances in the bacterial-fungal interactions, highlighting the roles of P.g and C.a in oral diseases, emphasizing the importance of developing treatment strategies for co-infection of P.g and C.a, and providing new ideas for the prevention and treatment of related diseases.

Objective To assess the clinical value of multimodal ultrasound score for assessment of endometrial receptivity among patients with polycystic ovary syndrome (PCOS), and to provide guidance for improving pregnancy outcomes among PCOS patients. Methods A total of 48 PCOS patients admitted to Jiangning Hospital Affiliated to Nanjing Medical University between January and December 2023 were enrolled as the case group, while 50 healthy women of childbearing age received ovulation monitoring at the same hospital during the same period served as the control group. Subjects received two-dimensional grayscale ultrasound during the implantation window (19 to 23 days of the menstrual cycle) for measurement of endometrial thickness, Gonen classification, and endometrial peristalsis. Two-dimensional color Doppler ultrasound was used for assessment of endometrial blood flow and three-dimensional ultrasound was used for assessment of endometrial volume and vascularization flow index (VFI). The endometrium multimodal ultrasound scores were estimated, and various parameters were compared between the two groups. The diagnostic performance of these parameters for PCOS was evaluated with receiver operating characteristic (ROC) curves. Results The age of subjects in the case group ranged from 20 to 38 years, with a mean age of (28.20 ± 2.82) years, and their body mass index (BMI) ranged from 21.23 to 29.11 kg/m², with a mean BMI of (26.25 ± 1.60) kg/m². The age of subjects in the control group ranged from 22 to 38 years, with a mean age of (28.10 ± 1.99) years, and their BMI ranged from 21.33 to 29.03 kg/m², with a mean BMI of (26.10 ± 1.78) kg/m². There were no significant differences between the case and control groups in terms of mean age, BMI, estradiol, and testosterone (t = 0.218, 0.422, 0.010, and 0.221; all P > 0.05). The endometrial thickness, endometrial volume, and VFI were significantly higher in the control group than in the case group (t = 4.838, 4.978, and 7.115; all P < 0.05). There were significant differences between the two groups in terms of endometrial classification, endometrial peristalsis pattern, and endometrial and sub-endometrial blood flow (Z = −4.136, −4.048, and −3.884; all P < 0.05). The scores of endometrial classification, endometrial peristalsis, endometrial and sub-endometrial blood flow, endometrial volume, VFI, and multimodal ultrasound were significantly lower in the case group than in the control group (t = 4.539, 4.449, 4.205, 3.209, 5.206, and 4.495; all P < 0.05). No significant difference was detected in the endometrial thickness score between the two groups (t = -0.149, P = 0.882). The areas under the ROC curves for endometrial thickness, endometrial volume, VFI, and multimodal ultrasound scores in diagnosis of PCOS were 0.753, 0.747, 0.809, and 0.858, respectively. Conclusion Multimodal ultrasound score provides a comprehensive assessment of the endometrium, and is effective in the assessment of endometrial receptivity, which may provide a reference for guiding pregnancy planning in PCOS patients.

ObjectiveTo explore the relationship between self-assessed health and age-adjusted Charlson comorbidity index （AICC） in older adults， and to further analyze the differences in this relationship across gender groups. MethodsBased on the China health and retirement longitudinal study （CHARLS） database， this study selected data on basic characteristics， chronic disease status， depressive symptoms， and self-assessed health of older adults aged ≥60 years. Chi-square tests were used to perform a preliminary analysis of the association between these factors and AICC scores. A multifactorial ordered logistic regression model was constructed to assess the effects of each influencing factor on AICC， while multiple linear regression analysis was used to explore the linear relationship between self-rated health and AICC scores. Additionally. Stratified analysis by gender was performed to evaluate gender differences. ResultsA total of 10 911 participants were included， with a mean age of 67.40±5.94 years； 6 249 （57.3%） were male and 4 662（42.7%） were female. The distribution of AICC scores was categorized into low-risk， moderate-risk， higher-risk， and high-risk groups， accounting for 23.5%， 50.2%， 20.6%， and 5.7%， respectively. Multifactorial logistic regression analysis revealed that self-rated health was negatively associated with AICC in the total population and in the male geriatric group （OR=0.843， 95% CI： 0.776， 0.917， P=0.001）， （OR=0.886， 95% CI： 0.796 ， 0.987， P=0.028）， but did not reach statistical significance in the female geriatric group . Linear regression analysis further indicated a significant negative linear relationship between self-rated health and AICC （b=-0.485， 95% CI： -0.516，-0.455， P＜0.001）.This relationship was consistent in both male （b=-0.356， 95% CI： -0.406，-0.305， P＜0.001） and female （b=-0.373， 95% CI： -0.435，-0.310， P＜0.001） subgroups， with a stronger negative association in females. ConclusionSelf-rated health is significantly negatively associated with AICC， and attention should be given to self-rated health in the female geriatric population. Self-rated health can serve as an important tool for identifying elderly group at high risk of comorbidities providing a valuable basis for precise intervention.

Objective:To evaluate the consistency of the Chinese three-dimensional anterior visual field analysis system (Scansys), the anterior segment analyzer (Pentacam), the frequency-domain anterior segment optical coherence tomography system (CASIA SS-1000), and a new ultra-high frequency digital ultrasound scanning system (Arcscan Insight100) to measure central vault after implantable collamer lens (ICL) implantation in myopic eyes with crystalline lenses.Methods:A diagnostic test study was conducted.Fifty-six myopic patients (56 eyes) who underwent ICL V4c implantation from June to December 2019 were included.Scansys, Pentacam, CASIA and Arcscan were used to measure the central vault after surgery.The vault measurements were compared.Correlations between the measurements of the four instruments were analyzed using Pearson correlation analysis, and consistency comparisons were analyzed using the Bland-Altman method.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2021[13]). Written informed consent was obtained from each subject.Results:The central vault measurements by Scansys, Pentacam, CASIA and Arcscan were (481.8±191.6), (476.4±190.6), (619.3±207.5) and (534.0±221.2)μm, respectively, with a statistically significant overall difference ( F=143.301, P<0.001). The vault measurements by Scansys and Pentacam were significantly lower than CASIA and Arcscan, and Arcscan was lower than CASIA, with statistically significant differences (all at P<0.001). There were strong positive correlations in vault measurements between Arcscan and CASIA, Arcscan and Pentacam, Arcscan and Scansys, CASIA and Pentacam, CASIA and Scansys, Pentacam and Scansys ( r=0.982, 0.933, 0.931, 0.942, 0.941, 0.989; all at P<0.001). Intraclass correlation coefficients of vault measurements by Scansys, Pentacam, CASIA and Arcscan were 0.985, 0.975, 0.998, 0.992, respectively.The 95% limits of agreement of vault measurements differences were -170 to 0, 0 to 280, 0 to 280, -110 to 210, -100 to 220 μm, between CASIA and Arcscan, CASIA and Scansys, CASIA and Pentacam, Arcscan and Scansys, Arcscan and Pentacam, respectively, and the maximum absolute value of the difference was beyond the clinically acceptable range, showing poor agreement.The 95% limits of agreement of vault measurement difference was -60 to 50 μm between Scansys and Pentacam, showing a good agreement. Conclusions:The repeatability of the vault after ICL V4c implantation in myopic eyes measured by the four instruments is good.Among them, the vault measurements of Scansys and Pentacam are smaller, showing good consistency, and their results could be substituted for each other.The measurement of CASIA is the largest, followed by Arcscan, which have a large difference from each other, and their results can not be substituted for each other, which should be comprehensively analyzed with the actual situation in clinical work.

Objective:To investigate the impact of the interval period between biopsy and MR examination on tumor detection and extraprostatic extension (EPE) assessment for prostate cancer (PCa) using multi-parametric MRI (mpMRI).Methods:The study was cross-sectional and retrospectively included 130 patients with PCa who underwent RP and preoperative systematic biopsies followed by mpMRI between January 2021 and December 2022 in the First Medical Center of Chinese PLA General Hospital. Patients were divided into 3 groups according to interval following biopsy (group A,<3 weeks, 31 cases; group B, 3-6 weeks, 67 cases; group C,>6 weeks, 32 cases). The percentages of hemorrhage volume in the total prostate were drawn on T 1WI and calculated. The junior, senior and expert radiologists independently localized the index lesions and calculated the accuracy for tumor detection, in addition to assessing the probabilities of EPE according to EPE grade. The correlation between the hemorrhage extent and interval was analyzed using the Spearman correlation coefficient. The accuracy for tumor detection was compared using χ2 test among groups. The diagnostic performance of the radiologists for EPE prediction was assessed using the receiver operating characteristic curve, and the differences between the corresponding area under the curve (AUC) were compared using the DeLong test. Results:The percentage of hemorrhage was correlated with the interval between biopsy and MR examination ( r=-0.325, P<0.001). The detection accuracy of junior radiologist was 83.9% (26/31), 76.1% (51/67), and 78.1% (25/32) in group A, B and C, respectively; no differences were observed in the detection accuracy among three groups ( χ2=0.76, P=0.685). The detection accuracy of senior radiologist was 83.9% (26/31), 80.6% (54/67), and 71.9% (23/32) in 3 groups with no differences ( χ2=1.53, P=0.464). The detection accuracy of expert radiologist was 80.6% (25/31), 77.6% (52/67), and 93.8% (30/32) with no differences ( χ2=3.95, P=0.139). The AUC (95% CI) for predicting EPE were 0.830 (0.652-0.940), 0.704 (0.580-0.809), 0.800 (0.621-0.920) in the group A, B and C for junior radiologist; 0.876 (0.708-0.966), 0.768 (0.659-0.863), 0.896 (0.736-0.975) for senior radiologist; and 0.866 (0.695-0.961), 0.813 (0.699-0.895), 0.852 (0.682-0.952) for expert radiologist, respectively. No differences were observed among the subgroups in each radiologist ( P>0.05). Conclusion:The interval period does not significantly affect the detection accuracy and EPE assessment of PCa using mpMRI. There is probably no necessity for prolonged intervals following systematic biopsy to preserve the clarity of MRI interpretation for PCa.
