AIM: To investigate the efficacy of Yangyin Yiqi Decoction combined with polyethylene glycol eye drops on dry eye disease after cataract surgery and its effect on inflammatory factors in tears.METHODS:Prospective study. A total of 104 patients(104 eyes)with dry eye disease after cataract surgery admitted to our hospital from April 2022 to March 2024 were selected and randomly divided into two groups: 52 cases(52 eyes)in the control group were treated with polyethylene glycol eye drops; 52 cases(52 eyes)in the combined group were treated with Yangyin Yiqi Decoction combined with polyethylene glycol eye drops. The dry eye symptom score, tear film stability index, tear inflammatory factor level, ocular surface disease index score(OSDI)and clinical efficacy of the two groups were compared before and after treatment.RESULTS:There were 6 cases(6 eyes)lost to follow-up, and 3 cases(3 eyes)were lost to follow-up in each group, with a loss to follow-up rate of 5.8%. The total effective rate of treatment in the combination group was significantly higher than that in the control group(94% vs 80%, P=0.037), and the Schirmer I test(SIt)and tear film break-up time(BUT)were higher than those in the control group(all P<0.05), and the dry eye symptom score, corneal fluorescein staining(FL)score, IL-1β, TNF-α, hs-CRP levels in tears and OSDI score were lower than those in the control group(all P<0.05).CONCLUSION:The combination of Yangyin Yiqi Decoction and polyethylene glycol eye drops provides an effective treatment plan for patients with dry eye disease after cataract surgery. It can effectively alleviate dry eye symptoms, reduce eye discomfort, improve tear film stability and ocular surface status, and reduce inflammatory factors in tears.

Objective:To investigate the risk of falls in patients with Parkinson's disease and establish and validate a prediction model.Methods:We selected 372 patients with Parkinson's disease at Sichuan Nanchong Mental Health Centre from January 2022 to Septem-ber 2023.The patients were divided in a 7:3 ratio into model group(260 cases)and validation group(112 cases).According to previ-ous literature and suspected factors found in clinical practice,we collected general information(sex,age,etc.)and disease-related factors(the duration of Parkinson's disease,the type of medications taken,etc.)that may be associated with falls in patients with Parkinson's disease.In the model group,between patients with and those without falls within 1 year as reported by the patients or their family members,potential predictors for falls were determined through comparison of general information and disease-related factors,least absolute shrinkage and selection operator(LASSO)regression,and multivariable logistic regression.Based on the significant factors,a nomogram model was established and validated.Results:In the model group,81(31.15%)of the 260 patients experienced falls.According to the LASSO regression and multivariable logistic regression results,alcohol consumption,the type of medications,the score of the Unified Parkinson's Disease Rating Scale part Ⅲ(UPDRS-Ⅲ),the Berg Balance Scale score,the presence of arthritis,and the presence of osteoporosis were independent factors influenc-ing falls in patients with Parkinson's disease.The area under curve(AUC)of the receiver operator characteristic curve(ROC)for pre-dicting the risk of falls in patients with Parkinson's disease was 0.896(95%CI=0.856-0.935)in the model group and 0.883(95%CI=0.840-0.926)in the validation group.The calibration curve analysis results showed that the prediction curves of the model and valida-tion groups closely fitted the standard curves.The decision curve analysis results indicated that when the probability threshold for pre-dicting the fall risk in Parkinson's disease using the nomogram was 0.10-0.90,the net benefit rate of the patients was greater than 0.Conclusion:The risk of falls in patients with Parkinson's disease are mainly influenced by factors such as alcohol consumption and the type of medications.The nomogram model established in this study can be used to predict the fall risk in patients with Parkinson's disease.

AIM: To explore the intervention effect of Dahuangtang pellets (DHT) on diabetic nephropathy (DN) based on the AMP-activated protein kinase/mammalian target of rapamycin/unc-51-like kinase 1 (AMPK/mTOR/ULK1) signaling pathway. METHODS: Eight mice were randomly assigned to the model group, the dapagliflozin group, and the DHT (high, medium, and low dosage) group out of a total of 40 C57BL/KSJ-db/db (hereafter referred to as db/db) mice; another 10 C57BL/KSJ-db/dm mice were used as the normal group, saline was provided to the normal and model groups, and the mice in the treatment group received the appropriate medications. The medications were given for 10 consecutive weeks, once per day, to the mice in the treatment group. At weeks 0, 4, 8, and 10 of administration, fasting blood glucose (FBG) was assessed by drawing blood at a predetermined time from the tail vein; Urine samples were taken at 0, 5, and 10 weeks after treatment to evaluate the levels of albumin and creatinine, and the urinary albumin-creatinine ratio (ACR) was computed. After 10 weeks, mice in each group were assayed for 24 h total urine protein, serum creatinine (Scr), urea nitrogen (BUN) levels; Western blotting analysis was conducted to detect the expression of p-AMPK, p-mTOR, and p-ULK1, as well as the expression of autophagy related proteins homolog of yeast Atg6 (Beclin-1), autophagy-related proteins microtubule-associated protein 1 light chain 3 (LC3), P62 in renal tissue; Immunohistochemistry was used to measure the expression of podocyte lacunar membrane proteins (Nephrin, Podocin) in renal tissues; The pathological morphology of renal tissue was observed by light microscopy and transmission electron microscopy. RESULTS: Compared with the model group, FBG, ACR, and 24 h total urine protein were reduced in the dapagliflozin group and DHT groups of mice, and there was no statistically significant difference in Scr and BUN; In renal tissues, there is increased expression of p-AMPK and p-ULK1, decreased expression of p-mTOR, increased expression of LC3II / LC3I and Beclin-1, and decreased expression of P62 (P<0.01, P< 0.05); differentially upregulated in glomeruli are the podocyte lacunar membrane proteins Nephrin and Podocin (P<0.01, P<0.05); renal pathologic damage was reduced to varying degrees; transmission electron microscopy showed an increase in the number of autophagic vesicles and autophagic lysosomes. CONCLUSION: DHT can delay the development of DN by regulating the AMPK / mTOR / ULK1 signaling pathway, enhancing podocyte autophagy, and protecting glomeruli.

Autoimmune hepatitis （AIH） is an autoimmune disease characterized by chronic liver inflammation， with a gradually increasing incidence rate， and its social and medical burdens cannot be neglected. Intestinal microecology is becoming a research hotspot in the field of autoimmune disease. In recent years， it has been believed that changes in intestinal microecology can cause changes in autoimmune state， microbial metabolites， and intestinal barrier， which is one of the driving factors for the onset of AIH. Early diagnosis and correct treatment can help to improve the prognosis of AIH patients. This article introduces the characteristics of gut microbiota in AIH patients， elaborates on the impact of intestinal microflora imbalance on the pathogenesis of AIH， and briefly describes related treatment regimens from the perspective of intestinal microecology， so as to comprehensively understand and explain the role of intestinal microecology in AIH and the impact of intestinal microecology balance on the pathogenesis， diagnosis， and treatment of AIH.

Objective:To assess the value of serum tumor specific protein 70 (SP70) for prognostic stratification in acute myeloid leukemia (AML).Methods:A cohort study design was adopted. 129 newly diagnosed AML patients from September 2022 to January 2024 at the Hematology Department of the First Affiliated Hospital of Nanjing Medical University were included, as well as a control group consisted of 120 healthy individuals and 7 cases with benign hematologic diseases during the same period (total 127 cases). Clinical data were collected from Electronic Medical Records. According to the 2023 edition of the Chinese Leukemia Diagnosis and Treatment Guidelines, AML patients with good or moderate prognosis were categorized as low-to-intermediate risk, while those with poor prognosis were high-risk group. Univariate and multivariate logistic regression analyses were used to identify variables significantly associated with AML prognostic risk. ROC analysis was used to evaluate diagnostic performance. A nomogram for predicting patient prognostic risk was constructed by R 4.0.2 software, and the internal validation was performed using bootstrapping.Results:Among 129 AML patients, there were 71 males (55.0%) and 58 females (45.0%), with 42 (32.6%) classified as high-risk and 87 (67.4%) as low-intermediate risk. The high-risk group had a significantly higher median age [62 (48, 67) years] compared to the low-intermediate risk group [50 (35, 63) years, Z=-2.381, P=0.017], and a significantly higher proportion of males (30 patients, 71.4%) compared to the low-intermediate risk group (41 patients, 47.1%, χ 2=6.760, P=0.009). Multivariate logistic regression analysis indicated that serum SP70 ( OR=2.54, 95% CI: 1.68-3.84, P<0.001), hemoglobin (HB) ( OR=0.96, 95% CI: 0.93-0.99, P<0.05), and bone marrow blast (BM blast) ( OR=1.07, 95% CI: 1.02-1.13, P<0.05) were independent risk factors for high-risk prognosis in AML patients. ROC analysis showed that the area under the curve (AUC) for SP70 predicting high-risk patients was 0.908 (cut-off value of 5.74 ng/ml, 95% CI: 0.845-0.952, sensitivity 90.5%, specificity 82.8%). The combined model of serum SP70, HB, and BM blasts had an AUC of 0.931 (95% CI: 0.890-0.973); C-index=0.925 (95% CI: 0.876-0.963),with no statistically significant difference compared to serum SP70 alone ( Z=1.693, P>0.05). Conclusion:Serum SP70 may be a promising non-invasive molecular biomarker for prognostic stratification in AML.
