OBJECTIVE: Peritoneal fibrosis (PF) is an adverse event that occurs during long-term peritoneal dialysis, significantly impairing treatment efficiency and adversely affecting patient outcomes. Astragaloside IV (AS-IV), a principal active component derived from Astragalus membranaceus (Fisch.) Bunge, has exhibited anti-inflammatory and antifibrotic effects in various settings. This study aims to investigate the potential therapeutic efficacy and mechanism of AS-IV in the treatment of PF. METHODS: The PF mouse model was established by intraperitoneal injection of 4.25% peritoneal dialysis fluid (100 mL/kg). The epithelial-mesenchymal transition (EMT) of HMrSV5 cells was induced by the addition of 10 ng/mL transforming growth factor β (TGF-β). The differentially expressed genes in HMrSV5 cells treated with AS-IV were screened using transcriptome sequencing analysis. The potential targets of AS-IV were screened using network pharmacology and analyzed using molecular docking and molecular dynamics simulations. RESULTS: Administration of AS-IV at doses of 20, 40, or 80 mg/kg effectively mitigated the increase in peritoneal thickness and the development of fibrosis in mice with PF. The expression of the fibrosis marker α-smooth muscle actin in the peritoneum was significantly decreased in AS-IV-treated mice. The treatment of AS-IV (10, 20, and 40 μmol/L) significantly delayed the EMT of HMrSV5 cells induced by TGF-β, as demonstrated by the decreased number of 5-ethynyl-2'-deoxyuridine-positive cells, reduced migrated area, and decreased expression of fibrosis markers. A total of 460 differentially expressed genes were detected in AS-IV-treated HMrSV5 cells through transcriptome sequencing, with notable enrichment in the phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K)-AKT serine/threonine kinase 1 (AKT) signaling pathway. The reduced levels of phosphorylated PI3K (p-PI3K) and p-AKT were detected in HMrSV5 cells with AS-IV treatment. Epidermal growth factor receptor (EGFR) was predicted as a direct target of AS-IV, exhibiting strong hydrogen bond interactions. The activation of the PI3K-AKT pathway by the compound 740Y-P, and the activation of the EGFR pathway by NSC 228155 each partially counteracted the inhibitory effect of AS-IV on the EMT of HMrSV5 cells. CONCLUSION AS-IV delayed the EMT process in peritoneal mesothelial cells and slowed the progression of PF, potentially serving as a therapeutic agent for the early prevention and treatment of PF.

OBJECTIVE: To observe the clinical effect of acupuncture for glaucoma-induced optic atrophy. METHODS: A total of 70 patients (89 affected eyes) with glaucoma-induced optic atrophy were randomized into an observation group and a control group, 35 cases in each group. The control group was given basic western medicine treatment. In the observation group, on the basis of the treatment in the control group, acupuncture was applied at main acupoints i.e. Baihui (GV 20), Shangjingming (Extra), Chengqi (ST 1), Fengchi (GB 20), Zusanli (ST 36), combined with supplementary acupoints based on syndrome differentiation, once every three days, twice a week. The treatment for 3 months was required in both groups. Before treatment, after treatment and in follow-up of 6 months after treatment, the best corrected visual acuity (BCVA), intraocular pressure (IOP), indexes of visual field (visual field index [VFI], mean deviation [MD], pattern standard deviation [PSD]) and mean thickness of retinal nerve fiber layer (RNFL) were observed in the two groups. RESULTS: Compared before treatment, BCVA was decreased after treatment and in follow-up in the control group (P<0.05); in the follow-up, BCVA in the observation group was higher than that in the control group (P<0.05). On each time point before and after treatment, there was no significant difference within or between the two groups (P>0.05). After treatment and in the follow-up, the mean thickness of RNFL was larger than the control group (P<0.05). CONCLUSION On the basis of the basic western medicine treatment, acupuncture can delay the decline of vision and the thinning of retinal nerve fiber layer in patients with glaucoma-induced optic atrophy.

AIM:To investigate the mechanism of curcumin inhibiting the choroidal neovascularization(CNV)of brown Norway(BN)rats.METHODS: CNV model of 36 BN rats was established through laser photocoagulation induction, and they were divided into 6 groups with 6 rats in each group. Normal group was fed normally with no intervention, while 532nm laser photocoagulation was used to establish a experimental CNV model in BN rats. Rats after modeling were respectively intervened for 14d and divided into model group, ranibizumab group, curcumin low [100mg/(kg·d)], medium [200mg/(kg·d)], and high [400mg/(kg·d)] dose group. The model group was given intragastric administration of saline for 14d, ranibizumab(10mg/mL, 0.2mL/dose)was injected at 2d after photocoagulation with 5μL once for rats in ranibizumab group, and different concentrations of curcumin were intragastrically administrated to the rats in low, medium and high groups for 14d. Fundus photography, fundus fluorescein angiography(FFA)and indocyanine green angiography(ICGA)examination were performed at 14d after photocoagulation. Ocular histopathological specimens of rats with CNV were made, and the central thickness of CNV were observed by HE staining. Ocular histopathological specimens were made, and the expressions of AKT/p-AKT/HIF-1α/VEGF signaling pathway-related proteins were observed by immunohistochemistry. The mRNA relative expressions of AKT/HIF-1α/VEGF factor in CNV tissues were detected by RT-qPCR, and the protein expressions of AKT/p-AKT/HIF-1α/VEGF factor in CNV tissues were detected by Western-blot.RESULTS: CNV generation rates in the model group, the ranibizumab group, and the low, medium and high-dose curcumin groups were 78.18%, 73.21%, 77.19%, 75.86%, 74.55%, respectively, which were higher than 70%. The average absorbance were 182.12±6.59, 119.22±8.03, 166.45±8.33, 164.34±5.69, 149.22±6.45, respectively; the ranibizumab group was significantly lower than the model group(P<0.05); the low-dose, medium-dose and high-dose groups were significantly higher than the ranibizumab group(P<0.05), and the curcumin high-dose group was significantly lower than the model group(P<0.05). HE staining showed that the retinal tissue structure of BN rats in normal group was clear and neatly arranged. The central thickness of CNV in the ranibizumab group was significantly reduced at 14d after photocoagulation compared with the model group(P<0.05); While the curcumin high-dose group was significantly reduced compared with the model group(P<0.05), but increased when compared with ranibizumab group(P<0.05). Immunohistochemistry results showed that AKT, p-AKT, HIF-1α, and VEGF factors were negatively expressed in the retinal tissue structure of BN rats in the normal group, and no brown-yellow reactants were found. The expression of AKT, p-AKT, HIF-1α, and VEGF factors in the model group were higher than that in the normal group at 14d after photocoagulation(P<0.05); the ranibizumab group was lower than the model group(P<0.05). While the expression of the curcumin high-dose group was significantly decreased compared with the model group(P<0.05), but significantly increased when compared with ranibizumab group(P<0.05). The mRNA results showed that the relative expression levels of AKT, HIF-1α and VEGF mRNA in the model group at 14d after photocoagulation were higher than those of the normal group(P<0.05); the ranibizumab group was lower than the model group(P<0.05). While curcumin high-dose group was significantly decreased compared with the model group(P<0.05), but significantly increased when compared with ranibizumab group(P<0.05). Western-blot results showed that there was no significant difference in the relative expression of AKT protein among each experimental groups at 14d after photocoagulation. The relative expression of p-AKT protein in the model group was significantly higher than that in the normal group(P<0.05); the ranibizumab group was significantly lower than the model group(P<0.05); the curcumin high-dose group was significantly lower than the model group(P<0.05). The relative expression levels of HIF-1α protein were significantly higher in the model group than in the normal group(P<0.05), and the ranibizumab group was lower than in the model group(P<0.05). The relative expression levels of HIF-1α protein was lower in the curcumin high-dose group than in the model group(P<0.05)but higher than ranibizumab group(P<0.05). The relative expression level of VEGF protein was significantly lower in the curcumin medium/high-dose group than in the model group(P<0.05).CONCLUSION: Curcumin at 400mg/(kg·d)has an inhibitory effect on CNV in BN rats. The mechanism may be closely related to inhibiting the activation of AKT/p-AKT/HIF-1α/VEGF signaling pathways.

The purpose of this study was to explore the effect and mechanism of dihydromyricetin (DHM) on Parkinson's disease (PD)-like lesions in type 2 diabetes mellitus (T2DM) rats. The T2DM model was established by feeding Sprague Dawley (SD) rats with high-fat diet and intraperitoneal injection of streptozocin (STZ). The rats were intragastrically administered with DHM (125 or 250 mg/kg per day) for 24 weeks. The motor ability of the rats was measured by balance beam experiment, the changes of dopaminergic (DA) neurons and the expression of autophagy initiation related protein ULK1 in the midbrains of the rats were detected by immunohistochemistry, and the protein expression levels of α-synuclein (α-syn), tyrosine hydroxylase (TH), as well as AMPK activation level, in the midbrains of the rats were detected by Western blot. The results showed that, compared with normal control, the rats with long-term T2DM exhibited motor dysfunction, increased α-syn aggregation, down-regulated TH protein expression, decreased number of DA neurons, declined activation level of AMPK, and significantly down-regulated ULK1 expression in the midbrain. DHM (250 mg/kg per day) treatment for 24 weeks significantly improved the above PD-like lesions, increased AMPK activity, and up-regulated ULK1 protein expression in T2DM rats. These results suggest that DHM may improve PD-like lesions in T2DM rats by activating AMPK/ULK1 pathway.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Objective: To evaluate the effect of postoperative radiotherapy and high-risk pathological factors on the prognosis of early-stage neuroendocrine carcinoma of cervix (NECC). Methods: A single-center retrospective cohort study of early-stage NECC in Peking Union Medical College Hospital from January 2011 to April 2022 were enrolled. The patients were treated with radical hysterectomy±adjuvant treatment. They were divided into postoperative non-radiation group and postoperative radiation group. The possible postoperative recurrence risk factors identified by univariate analysis were assessed using multivariate logistic regression. The Kaplan-Meier method was used to analyze the progression free survival (PFS), overall survival (OS), recurrence rate, and mortality rate. Results: (1) Sixty-two cases were included in the study, including 33 cases in postoperative non-radiation group and 29 cases in postoperative radiation group. (2) The median follow-up time was 37 months (ranged 12-116 months), with 23 cases (37%) experienced recurrences. There were 7 cases (11%) pelvic recurrences and 20 cases (32%) distant recurrences, in which including 4 cases (6%) both pelvic and distant recurrences. Compared with postoperative non-radiation group, the postoperative radiation group had a lower pelvic recurrence rate (18% vs 3%; P=0.074) but without statistic difference, a slightly elevated distant recurrence rate (24% vs 41%; P=0.150) and overall recurrence rate (33% vs 41%; P=0.513) without statistically significances. Univariate analysis showed that lymph-vascular space invasion and the depth of cervical stromal invasion≥1/2 were risk factors for postoperative recurrence (all P<0.05). Multivariate analysis showed lymph-vascular space invasion was an independent predictor for postoperative recurrence (OR=23.03, 95%CI: 3.55-149.39, P=0.001). (3) During the follow-up period, 18 cases (29%, 18/62) died with tumor, with 10 cases (30%, 10/33) in postoperative non-radiation group and 8 cases (28%, 8/29) in postoperative radiation group, without significant difference (P=0.814). The postoperative 3-year and 5-year survival rate was 79.2%, 60.8%. The depth of cervical stromal invasion≥1/2 was more common in postoperative radiation group (27% vs 64%; P=0.011), and postoperative radiation in such patients showed an extended trend in PFS (32.3 vs 53.9 months) and OS (39.4 vs 73.4 months) but without statistic differences (P=0.704, P=0.371). Compared with postoperative non-radiation group, the postoperative radiation did not improve PFS (54.5 vs 37.3 months; P=0.860) and OS (56.2 vs 62.4 months; P=0.550) in patients with lymph-vascular space invasion. Conclusions: Postoperative radiation in early-stage NECC patients has a trend to reduce pelvic recurrence but not appear to decrease distant recurrence and overall recurrence, and has not improved mortality. For patients with the depth of cervical stromal invasion≥1/2, postoperative radiation has a trend of prolonging OS and PFS but without statistic difference. Lymph-vascular space invasion is an independent predictor for postoperative recurrence, but postoperative radiation in such patients does not seem to have any survival benefits.

AIM: To investigate the effect and mechanism of curcumin on inhibiting choroidal neovascularization(CNV)in vitro. METHODS: Human retinal pigment epithelial(ARPE-19)cells chemical hypoxia model was established by cobalt chloride(CoCl2). CCK-8 method was used to detect the effect of curcumin on the activity of ARPE-19 cells induced by CoCl2. RT-qPCR and Western blot were used to detect the expression of AKT, HIF-1α, VEGF mRNA and protein in ARPE-19 cells hypoxia model induced by CoCl2. Cell scratch test, transwell chamber migration test, transwell chamber invasion test and matrigel matrix hose lumen formation test were used to observe the effects of conditioned medium of curcumin in ARPE-19 cells on the proliferation, migration, invasion and lumen formation of human umbilical vein endothelial cells(HUVEC)in non-contact condition. RESULTS:Chemical hypoxia model of ARPE-19 cells can successfully establish by CoCl2 at 100μmol/L. CoCl2 at the final concentration of 100μmol/L can promote the expression of AKT, HIF-1α and VEGF mRNA and p-AKT, HIF-1α and VEGF protein in ARPE-19 cells. Curcumin at the final concentration of 100μmol/L can reduce the expression of AKT, HIF-1α and VEGF mRNA in ARPE-19 hypoxia model. Curcumin at the final concentration of 100μmol/L can reduce the expression of AKT, HIF -1α and VEGF proteins in ARPE-19 hypoxia model. The conditioned medium of low(6.25μmol/L), medium(25μmol/L)and high dose(100μmol/L)curcumin in ARPE-19 cells can significantly inhibit the level migration of HUVEC. The conditioned medium in high dose group can significantly inhibit the vertical migration and cell invasion of HUVEC. The conditioned medium of middle and high dose curcumin in ARPE-19 cells can inhibit the lumen formation of HUVEC. CONCLUSION:Curcumin at 100μmol/L can protect ARPE-19 cells from hypoxia induced by CoCl2. Curcumin can inhibit the formation of blood vessels at the cellular level.

Objective: To explore the association between chronic hepatitis B virus infection and diabetes among adults. Methods: The baseline data of China Kadoorie Biobank ( CKB ) study from Tongxiang of Zhejiang Province was used for analysis. Community residents were investigated in the study from August 2004 to May 2008, including questionnaire survey, physical measurement and biological sample test. Univariate and multivariate logistic regression models were used to estimate the association of chronic hepatitis B virus infection with diabetes. Results: Totally 52 888 participants were included in the final analysis. The overall prevalence of HBsAg-positive was 3.55% ( N=1 877 ). The overall prevalence of diabetes was 5.17% ( N=2 733 ). The prevalence of HBsAg-positive in diabetic patients was 3.51% ( N=96 ). Both univariate and multivariate logistic regression models indicated that there was no association between chronic hepatitis B virus infection and diabetes（ P>0.05 ）. Conclusion No significant association has been found between chronic hepatitis B virus infection and diabetes among adults.

OBJECTIVE: To investigate the effects of different routes in placental mesenchymal stem cells (PMSC) on serum expression levels of IL-4, IL-17, TNF-α and IFN-γ in aplastic anemia (AA) rats. METHODS: The rat model of aplastic anemia (AA rats) was established by 5-fluorouracil combined with busulfan. The rats was divided into four groups: control, experimental, PMSC-injected into the tail vein, and PMSC-injected into the medullary cavity. The general state of rats in each group was observed in detail before and after treatment. The serum levels of interleukin-4 (IL-4) , interleukin-17 (IL-17), tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ) were measured by enzyme-linked immunosorbent assay (ELISA) at week 1, 3 and 5 after treatment. RESULTS: The serum levels of TNF-α, IFN-γ and IL-17 in the experimental group were significantly higher than those in the control group, while the level of IL-4 was significantly decreased (P＜0.05). The levels of TNF-α, IFN-γ and IL-17 gradually decreased after treatment while the level of IL-4 increased. By the fifth week, the above indexes were closed to the control group (P＞0.05), and the levels of TNF-α, IFN-γ and IL-17 in the group with PMSCs injected via the medullary cavity decrease more significantly than those group with PMSC injected via the tail vein, but level of IL-4 was not significantly different between two groups. CONCLUSION The level of serum hematopoietic negative regulators increase significantly, and the level of hematopoietic promoting factors decreases significantly in aplastic anemia rats. PMSC can down-regulate the level of hematopoietic negative regulators and up-regulate the level of hematopoietic promoting factors in the rats with aplastic anemia, and the inhibition of hematopoietic negative regulators by intramedullary injection is more significant than that by caudal vein injection.
