ObjectiveWith the development of society and the increasing demand for pregnancy at an advanced age, diminished ovarian reserve (DOR) has attracted wider attention. This disease affects the normal menstruation of women and poses a threat to their mental health. Current research on DOR is still in the initial stage, and advancing research progress in DOR necessitates the construction of effective and clinically relevant animal models. Building on existing literature and integrating the diagnosis criteria of DOR in traditional Chinese medicine (TCM) and Western medicine, this study summarized, analyzed, and evaluated existing models, providing a reference for optimizing DOR animal models. MethodsA retrospective analysis of literature on DOR-related animal models was conducted, and the diagnostic criteria of DOR in TCM and Western medicine were sorted out. By means of evaluation methods of animal models, the clinical relevance of each model to TCM and Western medicine was assessed. ResultsDOR animal models included those based on natural factors, iatrogenic factors, immune factors, metabolic factors, and environmental factors. Among them, the model based on iatrogenic factors, especially models induced by Tripterygium wilfordii preparations, cyclophosphamide, and cisplatin, had a high degree of relevance to both Western medical diseases and TCM syndromes and was confirmed as the optimal modeling method for studying DOR at present. ConclusionThe existing DOR modeling methods mostly have a high degree of clinical relevance to Western medical diseases, while the number of DOR animal models with clear TCM syndromes is very limited. TCM plays an indispensable role in exploring DOR treatment methods. Therefore, the development of DOR animal models related to TCM syndromes should be strengthened, further exploring the potential of TCM and providing strong theoretical support for the application of TCM in DOR treatment.

ObjectiveTo construct a rat model of psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type), and evaluate the macroscopic manifestations and microscopic indicators of the model. MethodsTwenty-two SD rats were divided into normal group (n=3), common psoriasis group (n=5), spleen deficiency and dampness obstruction syndrome (external dampness type) group (n=7), and psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type) group (n=7). The spleen deficiency and dampness obstruction syndrome (external dampness type) rat model was established through 32-week exposure to an artificially simulated high-humidity environment, while the common psoriasis model was developed via 7-day topical application of imiquimod cream, and these two approaches were combined to construct a composite model of psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type). Rats in the normal group were housed under normal humidity conditions. The general state, tongue manifestation of rats were observed to evaluate the macroscopic syndrome manifestations; the microscopic syndrome manifestations of rats were evaluated through adipose tissue and liver tissue changes; the severity of psoriasis in rats was evaluated through skin pathological changes, psoriasis area and severity index (PASI), proliferating cell nuclear antigen (PCNA) expression and spleen tissue changes; changes in rat CD4+ interferon-γ+ cells (CD4+IFN-γ+ cells), CD4+ tumour necrosis factor-α+ cells (CD4+ TNF-α+ cells), and forkhead framing protein P3+ regulatory T cells (CD3+CD4+FoxP3+ Treg cells) were detected by flow cytometry. ResultsMacroscopically, both the spleen deficiency and dampness obstruction syndrome (external dampness type) group and psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type) group exhibited manifestations of spleen deficiency and dampness obstruction, including lethargy, huddling behavior, dull and disheveled fur, as well as soft or loose stools and perianal soiling in some individuals; both these two groups displayed enlarged tongue, swollen, and moist tongue texture, accompanied by slippery tongue surface. Microscopically, compared to the common psoriasis group, the psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type) group showed increased epididymal fat index (P<0.05); compared to the normal group and spleen deficiency and dampness obstruction syndrome (external dampness type) group, the psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type) group demonstrated significantly elevated spleen mass (P<0.05), while hepatic gross morphology and HE staining revealed no significant histopathological changes across all groups. Dorsal skin lesions were markedly exacerbated in the psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type) group when compared to those in common psoriasis group. Both the common psoriasis group and psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type) group exhibited significantly higher erythema scores, scaling scores, infiltration scores, PASI total scores, and proportions of CD3+CD4+FoxP3+Treg cells compared to the normal group and spleen deficiency and dampness obstruction syndrome (external dampness type) group (P<0.05), with pronounced PCNA-positive expression observed in the epidermal basal layer and dermis; the psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type) group displayed significantly increased proportions of CD4+TNF-α+cells compared to the spleen deficiency and dampness obstruction syndrome (external dampness type) group (P<0.05); whereas no significant differences were detected in CD4+IFN-γ+cell proportions among groups (P>0.05). ConclusionThe rat model of psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type) can be successfully constructed by artificially simulating a high-humidity environment combined with imiquimod induction.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T NANC), time to symptom improvement (T SI), and time of hospital stay (T HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Objective:To investigate the clinicopathologic features and prognostic factors of breast cancer patients with tumor deposits in the ipsilateral axillary region.Methods:We retrospectively analyzed the clinicopathologic data and follow-up results of 155 patients with breast cancer diagnosed for the first time and complicated with tumor deposits in the ipsilateral axillary region in the Department of Thyroid-Breast-Vascular Surgery of Xijing Hospital from January 2008 to September 2018. Kaplan-Meier method was used for survival analysis. Log rank test was used for the univariate analysis of prognostic factors, and Cox regression was used for multivariate analysis.Results:The median disease free survival (DFS), median distant metastasis free survival (DMFS), and median overall survival (OS) of the 155 patients were 52.0 months, 66.6 months, and 102.2 months, respectively. The 5-year and 10-year DFS rates were 45.7% and 23.1%, the 5-year and 10-year DMFS rates were 56.9% and 28.9%, and the 5-year and 10-year OS rates were 79.3% and 46.0%, respectively. Multivariate Cox regression analysis showed that family tumor history ( HR=0.362, 95% CI: 0.140-0.937), clinical T stage (T3: HR=3.508, 95% CI: 1.380-8.918; T4: HR=2.220, 95% CI: 1.076-4.580), estrogen/progesterone receptor status ( HR=0.476, 95% CI: 0.261-0.866), number of tumor deposits ( HR=1.965, 95% CI:1.104-3.500) and neoadjuvant chemotherapy ( HR=1.961, 95% CI: 1.032-3.725) were independent influencing factors for DFS. Molecular subtype [human epidermal growth factor receptor-2(HER-2) positive and hormone receptor negative: HR=7.862, 95% CI: 3.189-19.379], number of tumor deposits ( HR=2.155, 95% CI: 1.103-4.212), neoadjuvant chemotherapy ( HR=5.002, 95% CI: 2.300-10.880) and radiotherapy ( HR=2.316, 95% CI: 1.005-5.341) were independent influencing factors of DMFS. Histological grade ( HR=4.362, 95% CI: 1.932-9.849), estrogen/progesterone receptor expression ( HR=0.399, 95% CI: 0.168-0.945), HER-2 expression ( HR=2.535, 95% CI: 1.114-5.768) and neoadjuvant chemotherapy ( HR=4.080, 95% CI: 1.679-9.913) were independent influencing factors of OS. Conclusions:The presence of tumor deposits weakens the influence of axillary lymph node status and distant metastases on the prognosis of breast cancer patients. Therefore, a clinicopathological staging system taking into account tumor deposits should be developed. Since the number of tumor deposits affects the risk of recurrence and metastasis of breast cancer patients, we recommend that the number of tumor deposits should be reported in detail in the pathological report after breast cancer surgery.

Objective:To investigate the predictive value of controlling nutritional status (CONUT) score in the prognosis of patients with advanced diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective case series study was performed. The clinical data of 654 patients newly diagnosed with advanced DLBCL diagnosed in 7 medical centers in Huaihai Lymphoma Working Group from October 2009 to January 2022 were retrospectively collected. All the patients received rituximab-based immune chemotherapy regimens. The patients were randomly assigned to the training set (458 cases) and the validation set (196 cases) in a 7:3 ratio. The clinicopathological data of patients were collected, and the CONUT score was calculated based on albumin, lymphocyte count, and total cholesterol. The optimal critical value of CONUT scote was determined by using MaxStat method. Kaplan-Meier method was used to draw survival curves; Cox proportional hazards model was used to make univariate analysis and multivariate analysis on the factors influencing overall survival (OS). The efficacy of CONUT score in combination with the International prognostic index (IPI) and an enhanced IPI (NCCN-IPI) in predicting OS was evaluated by using receiver operating characteristic (ROC) curves.Results:The median follow-up time of 654 patients was 38.1 months (95% CI: 35.3 months- 40.9 months), and the 5-year OS rate was 49.2%. According to the MaxStat method, the optimal critical value for CONUT score was determined to be 6 points. All the patients were classified into the normal nutritional status group (CONUT score ≤ 6 points, 489 cases) and the poor nutritional status group (CONUT score > 6 points, 165 cases). The results of the multivariate analysis showed that CONUT score > 6 points, male, lactate dehydrogenase >240 U/L, high white blood cell count, low hemoglobin level and age > 60 years were independent risk factors for OS of patients with advanced DLBCL (all P < 0.05). Patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group in the overall cohort of advanced DLBCL. Subgroup analysis revealed that among patients with Eastern Cooperative Oncology Group-performance status (ECOG PS) score < 2 points, IPI low-intermediate risk, IPI intermediate-high risk, NCCN-IPI low-intermediate risk, and NCCN-IPI intermediate-high risk, the patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group (CONUT score ≤ 6 points) (all P < 0.05). Conclusions:CONUT score has a certain value in the assessment of the prognosis of patients with advanced DLBCL, and its predictive efficacy is further improved when combined with IPI and NCCN-IPI.
