Tumor angiogenesis plays a crucial role in tumor proliferation, invasion and metastasis, representing one of the hallmarks of cancer. Cancer-associated fibroblasts (CAF), as the core component of tumor microenvironment, have a decisive impact on tumor angiogenesis. On the one hand, CAF can secrete various cytokines such as vascular endothelial growth factor and hepatocyte growth factor, which activate the related signaling pathways to promote angiogenesis; on the other hand, CAF-derived exosomes carry pro-angiogenic factors and specific microRNA that drive this process through multiple signaling cascades. In addition, CAF can also modify the extracellular matrix, create favorable conditions for angiogenesis, and interact with immune cells to promote angiogenesis by regulating macrophage polarization. Based on these mechanisms, anti-angiogenic therapy targeting CAF has become a new research hotspot, ProAgio protein, eicosapentaenoic acid and other formulations have shown potential therapeutic effects, and various biophysical therapies for CAF have also shown great potential, which are expected to bring new breakthroughs to tumor treatment in the future.

Objective:To examine the efficacy of uniportal video-assisted thoracoscopic surgery in the treatment of tuberculous destroyed lung.Methods:This is a retrospective case series study. The clinical data of 33 patients with tuberculous destroyed lung who had received uniportal video-assisted thoracoscopic pulmonary resection from June 2020 to May 2022 in Department of Surgery, Wuhan Pulmonary Hospital were retrospectively analyzed. There were 13 males and 20 females, aged (47.5±16.2) years (range: 19 to 68 years). The course of the disease was from 15 days to 8 years. All 33 cases had pleural adhesions, including 30 cases with total pleural adhesions and atresia. There were 21 cases of calcification of the thoracic lymph node, 17 cases of aspergillus infection, 4 cases of drug-resistant tuberculosis. The surgical incision was located at the midline of the fifth intercostal axilla, length 4 to 5 cm. The principle of separating pleural adhesions was easy first and difficult later, and then appropriate procedures were selected to resect the diseased lung based on the exploration situation. There were 12 cases that underwent superior lobectomy, 11 cases that underwent superior lobectomy and dorsal segmentectomy, 3 cases that underwent inferior lobectomy, 3 cases that underwent pneumonectomy, 2 cases that underwent middle and inferior lobectomy, and 1 case that underwent superior lobectomy, dorsal segmentectomy and basal segment wedgectomy. The surgical techniques, perioperative evaluation and treatment, management of complications, and the outcome were summarized.Results:Six cases were converted to thoracoscope assisted small incision or thoracotomy. For 27 cases who successfully underwent uniportal VATS, the operation time was (238.7±76.8) minutes (range: 60 to 420 minutes), the intraoperative bleeding was (400.4±315.9) ml (range: 50 to 1 200 ml). The duration of postoperative drainage was (12.7±8.3) days (range: 3 to 42 days). The postoperative hospital stay was (15.2±7.9) days (range: 6 to 43 days). Persistent postoperative pulmonary leakage occurred in 12 cases. There were 2 cases of active thoracic bleeding, one of which was cured with conservative treatment. The other case underwent secondary operation. One case of bronchopleural fistula was cured after continuous thoracic drainage to control infection and implantation of one-way bronchial valve through a fiberoptic bronchoscope.Conclusion:For selected patients with tuberculous destroyed lung, choosing the reasonable surgical procedures and techniques, the uniportal VATS could reduce surgical trauma.

AIM: To investigate the effects of 0.01% atropine eye drops on macular blood flow density and retinal thickness in children with different degrees of myopia. METHODS: This was a prospective case-control study. Sixty-four patients (112 eyes) diagnosed with myopia for the first time with 0.01% atropine eye drops before and 6 months after medication were investigated with the uncorrected distance visual acuity (UCVA), axial length (AL), spherical equivalent (SE), macular ganglion cell-inner plexiform layer thicknes (mGCIPL) using slit lamp examination and optical coherence tomography (OCT), vascular density in the macular area and the area of the avascular in the fovea using optical coherence tomography angiography (OCTA) . Changes in various indicators before and after medication were compared. RESULTS: Compared with before medication, the AL of the three groups of myopia patients increased significantly (P<0.01), the difference in low to moderate myopia group was significantly smaller than that in high myopia group. Compared with before medication, SE increased in all three groups of myopia patients, yet there was no statistically significant difference in the low - grade myopia group (P>0.05). The difference was statistically significant between the moderate myopia group and the high myopia group (P< 0.01). Compared with before medication, there was no change in intraocular pressure (IOP) among the three groups of myopic patients (P>0.05). After 6 months of medication, the central circle macular vessel density (cCVD) increased in the low myopia group and moderate myopia group (P<0.01), there was no statistically significant difference in the high myopia group (P>0.05). Before and after medication, there was no significant difference in outer circle macular vessel density (oCVD), inner circle macular vessel density (iCVD), and whole circle macular vessel density (wCVD) among the three myopia groups (P>0.05). The increase in mGCIPL was statistically significant in the low myopia group (P<0.01), but there was no statistically significant difference in the moderate myopia and high myopia groups (P>0.05). There was no significant difference in foveal avascular zone (FAZ) among the three myopia groups before and after medication (P>0.05). There was no correlation between CVD, AL, and SE in the three myopia groups (P>0.01). There was a low correlation between CVD and mGCIPL in the low myopia group (r=0.442, P<0.05), there was no correlation between CVD and mGCIPL in the moderate myopia and high myopia groups (P >0.01). CONCLUSION: 0.01% atropine can significantly reduce the rate of axial and refractive growth in children with low to moderate myopia, increase the density of central macular vessels, and increase the thickness of mGCIPL in children with low to moderate myopia.

Lung cancer is one of the most common malignancies and has the highest number of deaths among all cancers. Despite continuous advances in medical strategies, the overall survival of lung cancer patients is still low, probably due to disease progression or drug resistance. Ferroptosis is an iron-dependent form of regulated cell death triggered by the lethal accumulation of lipid peroxides, and its dysregulation is implicated in cancer development. Preclinical evidence has shown that targeting the ferroptosis pathway could be a potential strategy for improving lung cancer treatment outcomes. In this review, we summarize the underlying mechanisms and regulatory networks of ferroptosis in lung cancer and highlight ferroptosis-targeting preclinical attempts to provide new insights for lung cancer treatment.
