Among gynecologic malignancies, ovarian cancer is the most lethal, primarily due to its insidious early symptoms, lack of effective screening methods, and high risk of recurrence. It poses substantial challenges to clinical diagnosis and treatment. In recent years, the clinical application of poly ADP-ribose polymerase inhibitors has promoted a comprehensive management model that integrates targeted therapy with conventional treatments. This review, aiming to provide new perspectives and approaches for future research, summarizes the high-risk factors and first-line treatment strategies for ovarian cancer. Further studies should focus on optimizing personalized treatment strategies and exploring novel targeted therapies to improve patient survival outcomes.

ObjectiveTo explore the mechanism of Jiawei Wendantang in preventing and treating diabetic atherosclerosis by observing the effect of this prescription on the nuclear factor-κB / NOD-like receptor protein 3（NF-κB/NLRP3） pathway and related inflammatory cytokines in rat model of diabetic atherosclerosis. MethodFifty-four SPF-grade rats were randomized into blank， model， atorvastatin （0.9 mg·kg^-1·d^-1）， and high-， medium-， low-dose （18.2， 9.1， 4.55 g·kg^-1·d^-1， respectively） Jiawei Wendantang groups. The rats in other groups except the blank group were modeled for diabetic atherosclerosis by intraperitoneal injection of streptozotocin and feeding with a high-sugar high-fat diet， and those in the blank group were injected with an equal dose of citric acid buffer and fed with a regular diet. The drug administration lasted for 4 weeks， and the blood glucose level in the tail vein was measured every 6 days. After the last administration， the rats were anesthetized for sample collection. Enzyme-linked immunosorbent assay was employed to measure the serum levels of interleukin-18 （IL-18）， C-reactive protein （CRP）， tumor necrosis factor-α （TNF-α）， and intercellular adhesion molecule-1 （ICAM-1）. Western blot was employed to determine the relative protein levels of NF-κB p65， NLRP3， and ICAM-1 in the abdominal aorta. Real-time quantitative polymerase chain reaction was employed to determine the mRNA levels of NLRP3 and interleukin-1β （IL-1β） in the abdominal aorta. The pathological changes in the thoracic aorta were observed by hematoxylin-eosin staining. ResultCompared with the blank group， the model group showed elevated levels of IL-18， CRP， TNF-α， and ICAM-1 in the serum and blood glucose （P<0.05， P<0.01）， up-regulated protein levels of NF-κB p65， NLRP3， and ICAM-1 （P<0.01）， and up-regulated mRNA levels of NLRP3 and IL-1β （P<0.05）.

Moreover， Jiawei Wendantang alleviated the pathological injuries in the thoracic aorta. ConclusionJiawei Wendantang may modulate the NF-κB/NLRP3 signaling pathway to reduce the release and adhesion of inflammatory cytokines and regulate the blood glucose level to treat diabetic atherosclerosis.

ObjectiveTo explore the possible mechanism of the treatment of dry eye with liver-meridian constraint-heat syndrome by Runmu Xiaoyao Powder （润目逍遥散） by miR-146a-5p and interleukin-1 receptor-associated kinase 1/tumour necrosis factor receptor associated factor 6/nuclear factor-κB （IRAK1/TRAF6/NF-κB） signalling pathway. MethodsEighty C57BL/6J mice were randomly divided into normal group， model group， agonist group， inhibitor group， sodium hyaluronate group， and Runmu Xiaoyao Powder high-， medium-， and low-dose groups， with 10 mice in each group. Except for the normal group， the mice of dry eye with liver-meridian constraint-heat syndrome were modeled by using benzalkonium chloride solution eye drops combined with chronic pain stimulation. Beginning on the 30th day of modelling， mice in Runmu Xiaoyao Powder high-， medium-， and low-dose groups were given 29， 14.5， and 7.25 g/kg of Runmu Xiaoyao Powder respectively twice daily by gavage； mice in sodium hyaluronate group were given 5 μl of sodium hyaluronate drops twice daily； mice in the agonist group were given 2 nmol of agomir-146a-5p drops in each eye at a time， and those in the inhibitor group were given 5 nmol of antagomir-146a-5p drops in each eye， with every other day， 3 times per week； mice in the normal and model groups were gavaged with deionised water at 1 ml/（100 g·d）. The intervention was continued for 14 days in each group， and mice in each group were examined for tear secretion， tear film rupture time， corneal fluorescein staining， and irritability scores on the day following the last intervention； HE staining was used to observe the pathological conditions of the cornea and lacrimal glands in each group； corneal and lacrimal gland inflammatory factors， such as interleukin 1β （IL-1β）， tumour necrosis factor α （TNF-α）， miR-146a-5p expression， were examined； matrix metalloproteinase 3 （MMP-3） and matrix metalloproteinase 9 （MMP-9） expression in cornea， IRAK1， TRAF6， nuclear factor κB p65 （NF-κB p65） protein and mRNA expression in cornea and lacrimal gland， and phosphorylated nuclear factor κB p65 （p-NF-κB p65） protein expression were detected. ResultsCompared with the normal group， mice in the model group showed reduced tear secretion， shorter tear film rupture time， higher irritability score （P＜0.05）， and pathological examination showed staining in the centre of the cornea， obvious corneal damage， increased volume of lacrimal gland follicular cells， disordered arrangement， a large number of inflammatory cell infiltration， and increased neovascularisation； corneal and lacrimal gland tissues showed elevated expression of IL-1β and TNF-α， decreased expression of miR -146a-5p， elevated expression of IRAK1， TRAF6， NF-κB p65， p-NF-κB p65 protein and IRAK1， TRAF6， NF-κB p65 mRNA， and elevated expression of MMP-3， MMP-9 protein in the cornea （P＜0.05）. Compared with the model group， all of the above indexes were significantly improved in high-dose group of Runmu Xiaoyao Powder， while some indexes were improved in the sodium hyaluronate group and the middle- and low-dose Runmu Xiaoyao Powder groups （P＜0.05）. Compared with the model group， corneal and lacrimal IRAK1 and TRAF6 mRNA and IRAK1， TRAF6 and p-NF-κB p65 protein expression decreased in the agonist group； compared with the inhibitor group， IRAK1， TRAF6， NF-κB p65 mRNA and protein expression in the cornea and lacrimal gland in the Runmu Xiaoyao Powder groups decreased （P＜0.05）. ConclusionRunmu Xiaoyao Powder can negatively regulate the IRAK1/TRAF6/NF-κB signalling pathway in the cornea and lacrimal gland of mice with dry eye of liver-meridian constraint-heat syndrome by up-regulation of miR-146a-5p， so as to inhibit inflammatory response and reduce the damage of the ocular surface tissues， and the high doses group showed the best effect.

Objective:To explore the effect and molecular mechanism of circ_0000263 on HeLa cell activity, apoptosis, telomerase activity, and radiosensitivity.Methods:The Hela cells were divided into si-NC, si-circ, vector, circ_0000263, anti-NC, anti-miR-338-3p, miR-NC, miR-338-3p, si-circ+anti-NC, si-circ+ anti-miR-338-3p, si-circ+vector, si-circ+TERT, sh-NC, sh-circ groups. Reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR) was used to detect the expressions of circ_0000263 and miR-338-3p. Cell clone formation array was used to detect cell survival; cell counting kit-8 (CCK-8) to detect cell proliferation; flow cytometry to detect apoptosis; western blot method to detect the expressions of proliferating cell nuclear antigen (PCNA), Cleaved-casp3, telomerase reverse transcriptase (TERT) proteins; double luciferase assay to detect the targeting relationships of circ_0000263 and miR-338-3p, miR-338-3p and TERT; telomere repeat amplification enzyme linked immunosorbent assay (TRAR-ELISA) to detect telomerase activity.Results:Circ_0000263 was highly expressed in Hela cells, miR-338-3p was low expressed, and TERT was highly expressed; circ_0000263 was also highly expressed in Hela cells treated with radiation ( P＜0.05). Knockdown of circ_0000263 inhibited the clone formation and cell proliferation ability of HeLa cells, and enhanced the radiosensitivity and apoptosis of HeLa cells. In contrast, knockdown of circ_0000263 decreased PCNA protein expression level and enhanced Cleaved-casp3 protein expression level in HeLa cells ( P＜0.05). The apoptosis rate in the si-circ group was (13.19±1.12)%, which was higher than (6.80±0.62)% of si-NC group ( P＜0.05). The apoptosis rate in the si-circ+4 Gy group was (24.82±1.57)%, which was higher than (17.00±0.96)% of si-NC+4 Gy group ( P＜0.05). Circ_0000263 targeted regulated miR-338-3p, and miR-338-3p targeted regulated TERT. MiR-338-3p was lowly expressed in HeLa cells, and knockdown of circ_0000263 elevated miR-338-3p expression level in HeLa cells. Circ_0000263 regulated TERT expression and inhibited telomerase activity through miR-338-3p. MiR-338-3p/TERT can restore the effect of circ_0000263 on the radiosensitivity of Hela cells. The apoptosis rate in the si-circ+anti-NC group was (27.37±0.89)%, which was higher than (18.22±1.18)% of the si-circ+anti-miR-338-3p group ( P＜0.05). The apoptosis rate in the si-circ+vector group was (27.55±0.48)%, which was higher than (20.10±0.68)% of si-circ+TERT group ( P＜0.05). After 72 hours of radiation by 4 Gy, the cell survival fraction of si-circ+anti-NC group was 0.41±0.02, which was lower than 0.66±0.03 of the si-circ+anti-miR-338-3p group ( P＜0.05); the cell survival fraction of si-circ+vector group was 0.42±0.05, which was lower than 0.70±0.03 of si-circ+TERT group ( P＜0.05). Conclusion:Inhibiting the expression of circ_0000263 supresses the proliferation of Hela cells by regulating miR-338-3p/TERT, promotes apoptosis, inhibits telomerase activity, increases the radiosensitivity of cancer cells, and provides a theoretical basis for improving the radiosensitivity of Hela cells.
