ObjectiveRetinal vein occlusion （RVO） is the second most common vascular disease leading to vision loss. Since its pathogenesis remains unclear， current Western medical treatments primarily target complications such as macular edema and neovascularization. The main therapeutic approaches include intravitreal injections of anti-vascular endothelial growth factor （VEGF） agents or corticosteroids， laser photocoagulation， and pars plana vitrectomy. However， these treatments cannot fully reverse disease progression or structural damage. Traditional Chinese medicine （TCM） has unique advantages in the clinical diagnosis and treatment of RVO， and integrated Chinese and Western medicine approaches may offer better clinical outcomes. This study， based on the clinical manifestations of RVO， systematically reviews the existing literature and evaluates the alignment of current RVO animal models with clinical manifestations. The aim is to identify the characteristics and limitations of existing models and provide recommendations and prospects for developing RVO animal models featuring the combination of disease and syndrome. MethodsDatabases including CNKI， Wanfang Data， PubMed， and Web of Science were searched with the keywords of "retinal vein occlusion" and "animal model". Model characteristics were assessed based on the diagnostic criteria for diseases and syndromes in both TCM and Western medicine. The alignment of each model with clinical manifestations was analyzed and evaluated. ResultsThe available RVO models were primarily established via methods such as laser photocoagulation， photodynamic therapy， diathermy， intravitreal drug injection， and mechanical modeling. These models demonstrated moderate overall alignment with clinical manifestations， mainly reflecting disease characteristics. However， they generally lack representation of TCM syndrome features. ConclusionExisting RVO models are predominantly based on Western medicine and lack TCM syndrome features. Western medical treatments for RVO have certain limitations， while syndrome differentiation and treatment in TCM offer potential advantages. Future research should focus on developing disease-syndrome integrated animal models that incorporate both pathological features and TCM syndrome characteristics. This approach will enhance the design of RVO models and facilitate both basic and clinical research， which make it a scientifically valuable and necessary endeavor.

Perineural invasion (PNI) by tumor cells is a key phenotype of highly-invasive oral squamous cell carcinoma (OSCC). Since Schwann cells (SCs) and fibroblasts maintain the physiological homeostasis of the peripheral nervous system, and we have focused on cancer-associated fibroblasts (CAFs) for decades, it's imperative to elucidate the impact of CAFs on SCs in PNI⁺ OSCCs. We describe a disease progression-driven shift of PNI^- towards PNI⁺ during the progression of early-stage OSCC (31%, n = 125) to late-stage OSCC (53%, n = 97), characterized by abundant CAFs and nerve demyelination. CAFs inhibited SC proliferation/migration and reduced neurotrophic factors and myelin in vitro, and this involved up-regulated ER stress and decreased MAPK signals. Moreover, CAFs also aggravated the paralysis of the hind limb and PNI in vivo. Unexpectedly, leukemia inhibitory factor (LIF) was exclusively expressed on CAFs and up-regulated in metastatic OSCC. The LIF inhibitor EC330 restored CAF-induced SC inactivation. Thus, OSCC-derived CAFs inactivate SCs to aggravate nerve injury and PNI development.

Objective: To utilize machine learning(ML) algorithms to develop accurate and effective prediction models for TAC dose/weight-adjusted trough concentration(C0/D). Methods: Data were collected on 264 TAC blood concentration monitoring data from 72 patients undergoing kidney transplantation. The effects of population statistical data, clinical features, combined medication, and ultrasound feature parameters on TAC C0/D were analyzed. Features with a significance level less than 0.05 in the univariate analysis of TAC C0/D were selected for inclusion in the random forest(RF) algorithm to identify significant features. These features were interpreted using partial dependency plots. Five ML algorithms, including RF, support vector regression(SVR), extreme gradient boosting(XGBoost), decision trees(DT) and artificial neural networks(ANN), were employed to establish the TAC C0/D prediction model. Hyper-parameter tuning was performed on the RF model that performed the best. Results : Ten characteristic variables with importance scores>5 were retained and included in the ML model: transglutaminase, red blood cell count, blood urea nitrogen, weight, serum creatinine, renal segmental arterial resistance index, renal aortic resistance index, hematocrit, renal pelvic Young′s modulus value, and time after transplantation. The partial dependence plots showed that all 10 important variables screened were positively correlated with TAC C0/D. The tuned RF model outperformed the other models with aR2of 0.81, aRMSEof 43.93, and aMAEof 29.97. Conclusion The ML models demonstrate good performance in predicting TAC C0/D and provide innovative interpretations using partial dependence plot. The optimized RF model shows optimal performance and offers a novel tool for individualized medication adjustment for TAC in renal transplant patients.

Objective:To discuss the clinical features and prognostic factors of adrenal metastases.Methods:The clinical data of 37 patients with adrenal metastases admitted to the First Affiliated Hospital of Guangxi Medical University from May 2015 to August 2022 were retrospectively analyzed. There were 30 males and 7 females. The median age was 54 (43, 62) years old, including 13 cases aged ≥60 years old and 24 cases aged < 60 years old. There were 22 cases of right metastasis, 12 cases of left metastasis and 3 cases of bilateral metastasis. The maximum diameter of metastatic carcinoma was <3 cm in 10 cases, 3-6 cm in 18 cases, and >6 cm in 9 cases. There were 20 cases of synchronous metastasis (diagnosed with adrenal metastasis at the same time as the primary tumor) and 17 cases of metachronous metastasis (found after the diagnosis of primary tumor). There were 20 cases of adrenal metastasis alone and 17 cases of adrenal metastasis combined with other distant metastasis. 16 cases underwent adrenalectomy, 15 cases underwent adrenalectomy combined with other organ resection, and 6 cases underwent ultrasound-guided needle biopsy. 18 patients were treated with surgery alone, and 19 patients were treated with combined treatment (surgery, chemotherapy, radiotherapy, immunotherapy, targeted therapy, interventional therapy and seed implantation). There were 12 cases of hepatocellular carcinoma, 8 cases of renal clear cell carcinoma, 5 cases of lung adenocarcinoma, 2 cases of colon adenocarcinoma, 2 cases of neuroblastoma, 1 case of renal pelvis carcinoma, 1 case of gastric adenocarcinoma, 1 case of cholangiocarcinoma, 1 case of renal papillary cell carcinoma, 1 case of colon adenosquamous carcinoma, 1 case of thymic small cell carcinoma, 1 case of endometrial carcinoma, and 1 case of diffuse large B-cell lymphoma. The Kaplan-Meier method was used to draw the survival curve, the log-rank test was used to analyze the relationship between the clinical characteristics of patients and overall survival (OS) and progression-free survival (PFS), and the Cox proportional hazards regression model was used to analyze the factors affecting OS.Results:The median follow-up time of the 37 patients was 10 (4, 18.5) months.The overall survival rates at 6 months, 1 year and 2 years were 59.5% (22/37), 43.2% (16/37) and 32.4% (12/37), respectively. The 6-month, 1-year and 2-year overall survival rates of 18 patients who underwent surgery alone were 66.7% (12/18), 44.4% (8/18) and 27.8% (5/18), respectively. The 6 months, 1 year and 2 years overall survival rates of 19 patients with comprehensive treatment were 52.6% (10/19), 42.1% (8/19) and 36.8% (7/19), respectively. There was no significant difference in overall survival rate between the two groups ( P=0.773). Kaplan-Meier survival curve analysis showed that the side of metastatic cancer was a risk factor for OS ( P=0.012) and PFS ( P=0.013), and the time of diagnosis of metastatic cancer was a risk factor for OS ( P=0.021). Univariate Cox regression analysis showed that, time to diagnosis of metastases ( HR=2.5, 95% CI 1.1-5.4, P=0.021), side of metastases ( HR=3.6, 95% CI 1.5-8.5, P=0.004), pulmonary metastases ( HR=3.6, 95% CI 1.1-11.0, P=0.032) and adenocarcinoma of the primary tumor ( HR=3.2, 95% CI 1.2-8.8, P=0.025) were risk factors for OS. Multivariate Cox regression analysis showed that simultaneous presence of metastases ( HR=2.6, 95% CI 1.1-6.2, P=0.033) and metastases located on the left side ( HR=3.6, 95% CI 1.5-8.6, P=0.005) were independent risk factors for OS. Conclusions:Hepatocellular carcinoma is the most common pathological type of adrenal metastases in this study. Patients may benefit from combined therapy based on surgery. The time of diagnosis, side, tumor origin and pathological type of primary tumor are the prognostic factors of adrenal metastases. Simultaneous presence of metastases and left-sided metastases are independent risk factors for OS in patients with adrenal metastases.

Objective: To analyze the influencing factors for hospitalization costs among stroke patients with different subtypes, so as to provide the reference for reducing the economic burden of patients. Methods: Data of patients with hemorrhagic or ischemic stroke who were discharged from hospitals in Nanshan District, Shenzhen City from January 1, 2016 to December 31, 2021 were collected through Hospital Information System. Hospitalization costs were analyzed between hemorrhagic and ischemic stroke patients, and factors affecting hospitalization costs among stroke patients with different subtypes were identified using a structural equation model. Results: A total of 10 298 patients with stroke were recruited, including 2 820 patients with hemorrhagic stroke (27.38%) and 7 478 patients with ischemic stroke (72.62%). The patients with hemorrhagic stroke had a median duration of hospital stay of 19.00 (interquartile range, 18.00) d, and a median hospitalization cost of 26 759.48 (interquartile range, 51 000.87) Yuan. The patients with ischemic stroke had a median duration of hospital stay of 12.00 (interquartile range, 10.00) d, and a median hospitalization cost of 12 199.87 (interquartile range, 13 290.20) Yuan. Structural equation model analysis showed that department of hospitalization, discharge status, ways of leaving hospital, surgery and hypertension had direct effects on hospitalization costs and indirect effects on hospitalization costs through duration of hospital stay among hemorrhagic stroke patients, and duration of hospital stay had the highest total effect (0.684), followed by surgery (0.632). Employment status, admission route, department of hospitalization, ways of leaving hospital, payment mode, surgery and dyslipidemia had direct effects on hospitalization costs and indirect effects on hospitalization costs through duration of hospital stay among ischemic stroke patients, and duration of hospital stay (0.746), surgery (0.424) and department of hospitalization (0.151) ranked the top three in total effects. Conclusion The hospitalization cost is relatively high among stroke patients in Nanshan District, and duration of hospital stay and surgery have great influence on hospitalization costs among stroke patients with different subtypes.

Objective:To investigate the effects of repetitive transcranial magnetic stimulation (rTMS) on learning-memory and the expression of synaptic plasticity proteins in hippocampus of rats with post-stroke sleep deprivation.Methods:A total of 28 SPF grade healthy male Wistar rats with 8-week old were randomly divided into four groups (control group, sham operation group, model group and rTMS group) according to random number table method, with 7 rats in each group. The rats in the model group and the rTMS group were treated with middle cerebral artery occlusion and p-chlorophenylalanine intraperitoneal injection to establish the post-stroke sleep deprivation model. The rats in the rTMS group were treated with rTMS intervention for consecutive 14 days after modeling. The rats in the sham operation group were only separated arteries but not ligated and inserted. The rats in control group were fed normally. The open field test (OFT) was used to observe the autonomous behavior of rats.The water maze test(WMT) was used to observe the spatial learning and memory ability of rats.The content of tyrosine kinase receptor type B(TrkB) in hippocampus was detected by Western blot.The expressions of brain-derived neurotrophic factor(BDNF) and immediate early gene c-fos in hippocampus were detected by immunofluorescence.The morphology and structure of neurons in hippocampus were observed by optical microscopy and transmission electron microscopy. SPSS 21.0 software was used for statistical analysis, and repeated measurement ANOVA was used for the escape latency data, one-way ANOVA was used for the comparison of other data among multiple groups, and LSD test was used for further pairwise comparison.Results:(1) The OFT results showed that there were statistical differences in the numbers of crossing squares, upright times and total points of rats in the four groups after intervention ( F=27.638, 10.425, 30.690, all P<0.001). The numbers of crossing squares ((72.71±10.10)), upright times ((6.57±0.87)times) and total points ((79.29±10.03) points) of rats in rTMS group were all higher than those in model group after intervention ((43.71±6.96), (3.43±0.65)times, (47.14±6.82)points) (all P<0.05). As for the escape latency of WMT among the four groups of rats, the interaction effect was not significant( F=1.108, P=0.37), and the time main effect( Ftime=27.295, Ptime<0.01) and group main effect ( Fgroup=8.691, Pgroup<0.01) were significant after rTMS intervention.On the 3rd and 4th day, the escape latency of rTMS group rats was lower than that of the model group (both P<0.01). There were statistically significant differences in the numbers of crossing platform, swimming distance and residence time in target quadrant of rats in the four groups after intervention( F=8.569, 3.308, 3.547, all P<0.05). The numbers of crossing platform ((2.00±0.31)times), swimming distance in target quadrant ((196.95±24.57) cm) and residence time ((17.72±1.36)s) of rats in rTMS group were all higher than those in model group after intervention ((1.57±0.30)times, (146.61±4.79) cm, (13.58±0.98)s)(all P<0.05). (2)Optical microscopy and transmission electron microscopy showed that the hippocampal cells arranged irregularly, the organelles' integrity was destroyed in the model group compared with the normal control group. In rTMS group the arrangement and structure of nerve cells in the hippocampus were improved after rTMS intervention. (3) The immunofluorescence results showed that c-fos (1.49±0.09) and BDNF (0.84±0.06) in the hippocampus of rats in rTMS group were both higher than those in model group ((1.24±0.12), (0.48±0.08))(both P<0.05). The Western blot results showed that the expression level of TrkB (1.81±0.03) in the hippocampus of rats in rTMS group was higher than that in model group (0.96±0.02) ( P<0.05). Conclusion:The rTMS can improve the learning-memory ability and autonomous capacity of rats with post-stroke sleep deprivation, which may be related to promoting the expression of c-fos, BDNF and TrkB in hippocampus tissue.

Objective:To explore the possible effects of Bushen Huoxue Formula (the kidney tonifying and blood activating prescription) on the proliferation and extracellular matrix synthesis of nucleus pulposus cells by regulating the circ_0036763/miR-583 axis.Methods:Real time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression levels of circ0036763 and miR-583 in normal and intervertebral disc degeneration (IDD) nucleus pulposus cells; IDD nucleus pulposus cells were divided into pcDNA group, pcDNA circ_0036763 group, pcDNA circ_0036763+ mimic NC group, and pcDNA circ_0036763+ miR-583 mimic group. qRT-PCR was used to detect the expression levels of circ_0036763 and miR-583 in nucleus pulposus cells in each group, methyl thiazolyl tetrazolium (MTT) was used to detect cell proliferation (A value), and Western blot was used to detect the expression of proliferating cell nuclear antigen (PCNA), collagen Ⅰ, and collagen Ⅱ proteins in nucleus pulposus cells, The dual luciferase assay reported experimental validation of the targeting relationship between circ_0036763 and miR-583. 27 mice were divided into sham surgery group, IDD group, and kidney tonifying and blood activating formula group. IDD models were established in all groups except for the sham surgery group. After successful modeling, the sham surgery group and IDD group were given physiological saline by gavage, while the kidney tonifying and blood activating formula group was given 1.5 g/ml of kidney tonifying and blood activating formula by gavage for 3 consecutive weeks. QRT-PCR was used to detect the expression levels of circ0036763 and miR-583 in the nucleus pulposus cells of mice in each group, MTT was used to detect cell proliferation, and Western blot was used to detect the expression of PCNA, collagen Ⅰ, and collagen Ⅱ proteins.Results:The expression level of circ_0036763 in IDD nucleus pulposus cells decreased, while the expression level of miR-583 increased (all P<0.05); Overexpression of circ_0036763 can promote proliferation and extracellular matrix synthesis of nucleus pulposus cells (all P<0.05); Circ_0036763 targets miR-583 and upregulates miR-583 reversible overexpression. Circ_0036763 enhances the proliferation and extracellular matrix synthesis ability of IDD nucleus pulposus cells. Compared with the sham surgery group, the IDD group showed an increase in collagen Ⅰ protein expression and miR-583 expression levels (all P<0.05), while the cell A value, PCNA and collagen Ⅱ protein expression, and circ_0036763 expression levels decreased (all P<0.05); Compared with the IDD group, the Kidney Tonifying and Blood Activating Formula group showed a decrease in collagen Ⅰ protein expression and miR-583 expression levels (all P<0.05), while the cell A value, PCNA and collagen Ⅱ protein expression, and circ_0036763 expression levels increased (all P<0.05). Conclusions:The kidney tonifying and blood activating formula (Bushen Huoxue) may induce proliferation and extracellular matrix synthesis of nucleus pulposus cells by regulating the circ_0036763/miR-583 axis.

Objective:To comprehensively understand the disease burden of liver cirrhosis and other chronic liver diseases caused by alcohol use in China from 1990 to 2019, as well as to predict the trends in disease burden from 2020 to 2030.Methods:The analysis utilized data from the Global Burden of Disease study in 2019 (GBD2019). Key indicators such as incidence rate, mortality rate, disability-adjusted life years (DALY), years of life lost due to premature mortality, and years lived with disability were selected to describe the disease burden of alcohol-related liver cirrhosis and other chronic liver diseases in China from 1990 to 2019. The estimated annual percentage change (EAPC) was used to depict the temporal trends in disease burden. Furthermore, a Bayesian age-period-cohort (BAPC) model was constructed using R software to predict the age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) of alcohol-related liver cirrhosis and other chronic liver diseases in China from 2020 to 2030.Results:From 1990 to 2019, the incidence of alcohol-related liver cirrhosis and other chronic liver diseases in China showed an upward trend, with an EAPC of 0.31% (95% CI: 0.10%-0.52%). However, the DALY declined, with an EAPC of -2.81% (95% CI: -2.92% - -2.70%). The ASMR showed a downward trend, with an EAPC of -2.55% (95% CI: -2.66% - -2.45%). The highest incidence of cirrhosis of liver caused by alcohol and other chronic liver diseases was reported in the age group of 35-49 years, while the ASMR increased gradually with age, with a significant rise after the age of 30. The age-standardized DALY rate peaked between the ages of 55 and 64. The disease burden indicators for males were consistently higher than those for females during the same period. According to the predictions of the BAPC model, from 2020 to 2030, the ASIR for cirrhosis of liver caused by alcohol and other chronic liver diseases in the entire population of China was projected to increase from 3.45/100 000 in 2020 to 3.78/100 000 in 2030, a growth of 9.57%. Conversely, the ASMR was expected to decrease from 1.45/100 000 in 2020 to 1.24/100 000 in 2030, a reduction of 14.48%. Conclusions:The disease burden of cirrhosis of liver caused by alcohol and other chronic liver diseases remained serious in China, especially in men and the middle-aged to elderly population. There is a pressing need to prioritize attention and resources towards these groups. Despite the projected decrease in ASMR, the ASIR continued to rise and is expected to persist in its upward trend until 2030.

Objective:To examine the burden and trends of acute viral hepatitis in Guangdong Province from 1990 to 2019, and provide reference evidences for hepatitis prevention and control in the province.Methods:Data on acute viral hepatitis (hepatitis A, B, C, and E) in Guangdong from 1990 to 2019 were extracted from the Global Burden of Disease Study 2019 database. The incidence, prevalence, mortality, and disability-adjusted life years (DALY) data were analyzed by age and gender, and the estimated annual percentage change (EAPC) was calculated to describe the changing trends in disease burden.Results:From 1999 to 2019, the standardized incidence, prevalence, mortality, and DALY of acute viral hepatitis in Guangdong were higher than the national averages. In 2019, 51.43% (2 245 087/4 365 221) of acute viral hepatitis cases in Guangdong Province were mainly attributed to hepatitis B, and 77.18% (106/138) of deaths were due to acute hepatitis B. In different age groups, except for acute hepatitis B, which was more common in adults, the incidence rates of other types of viral hepatitis such as hepatitis A, B, and E showed an overall decreasing trend with age. The mortality rates of different types of acute viral hepatitis, except for the <5 age group, increased with age. The overall incidence and mortality rates of acute viral hepatitis were higher in men than in women.Conclusions:The overall burden of acute viral hepatitis in Guangdong declined in 2019, but remained higher than the national level. Further efforts are needed to strengthen hepatitis prevention and screening in different population in Guangdong Province, especially in children and the elderly.
