RESUMO
ObjectiveTo evaluate the efficacy and safety of first-line transcatheter arterial chemoembolization （TACE） combined with targeted therapy and immunotherapy in the treatment of patients with stage Ⅱb/Ⅲa hepatocellular carcinoma （HCC） based on China Liver Cancer Staging （CNLC）. MethodsA total of 198 patients who received first-line TACE combined with targeted therapy and immunotherapy or received TACE alone from January 2015 to December 2022 in the First Affiliated Hospital of Soochow University were enrolled in this study， and after propensity score matching， there were 50 patients in combination group and 50 patients in TACE group. The Kaplan-Meier method was used to calculate median overall survival （mOS） and median progression-free survival （mPFS）. Modified Response Evaluation Criteria in Solid Tumors was used to evaluate objective response rate （ORR） and disease control rate （DCR）， and Common Terminology Criteria for Adverse Events v5.0 was used to evaluate adverse events. The chi-square test was used for comparison of categorical data between two groups； the t-test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups. The Kaplan-Meier method was used to estimate survival time and calculate 95% confidence interval （CI）， and the Log-rank test was used for comparison of mOS and mPFS between two groups. ResultsThe combination group had an mOS of 30.1 months （95%CI： 21.9 — 38.3）， and the TACE group had an mOS of 14.5 months （95%CI： 11.0 — 18.0）， with a significant difference between the two groups （χ2=17.8， P<0.001）； the combination group had an mPFS of 10.3 months （95%CI： 8.8 — 11.8）， and the TACE group had an mPFS of 7.1 months （95%CI： 5.8 — 8.4）， with a significant difference between the two groups （χ2=10.4， P<0.001）. There were significant differences between the combination group and the TACE group in ORR （84% vs 58%， P<0.05） and DCR （94% vs 80%， P<0.05）. There was no significant difference between the combination group and the TACE group in the incidence rate of adverse events （24% vs 16%， P=0.317）， and no adverse event-related deaths were observed in either group. ConclusionCompared with TACE alone， TACE combined with targeted therapy and immunotherapy has a better efficacy in the treatment of patients with CNLC stage Ⅱb/Ⅲa HCC， without increasing the incidence rate of severe adverse events.
RESUMO
Objective:To observe and analyze the clinical features, treatment methods and efficacy of patients with retinopathy associated with incontinentia pigmenti (IP).Methods:A retrospective case study. Twelve clinical confirmed IP patients (24 eyes) in Zhongshan Ophthalmic Center of Sun Yat-sen University from January 2015 to December 2018 were included in this study. The best corrected visual acuity and intraocular pressure examination were performed in patients (>4 years old). All patients were examined on the anterior segment, vitreous body, and fundus under topical anesthesia or general anesthesia. Eight cases underwent genetic testing. Patients with active disease should be given anti-vascular endothelial growth factor (VEGF) drug treatment, retinal laser photocoagulation or vitrectomy, those without active disease should be observed. All patients were followed up for 1 to 3 months, with an average follow-up time of 18.7 months.Results:All patients were all female, with an average age of 6.3±9.8 years old at the first ophthalmology visit. According to the recommendations of the pediatrician, 3 cases were actively screened for ophthalmology (referrals), with an average age of 0.4±0.5 years (median age: 2 months). A total of 9 cases were not recommended for referrals (non-referrals), including 3 cases of ophthalmology who were diagnosed for the first time due to visual impairment, and 6 cases of undiagnosed IP before the ophthalmology visit, the average age of their first visit was 8.2±10.8 years (medium age: 3 years old). The age of the first visit for non-referred patients was larger than that of referrals, and the difference was statistically significant ( Z=-2.141, P=0.036). Among the 24 eyes of 12 cases, there were no obvious fundus abnormalities in 1 case or 2 eyes, 11 cases of IP-related retinopathy in 22 eyes (91.7%, 22/24), 8 cases of binocular asymmetry (66.7%, 8/12). There were active lesions on the fundus in 7 eyes (29.2%, 7/24). Patients underwent simple retinal laser photocoagulation and/or anti-VEGF drug therapy. During the follow-up, retinal neovascularization recurred in 1 eye. Among the 8 cases that underwent genetic testing, 3 cases (37.5%, 3/8) were deleted in exons 4-10 of the IKBKG gene. Conclusions:IP is more common in women. IP-associated retinopathy is noted with early-onset, asymmetrical retinopathy, which is identified with retinal neovascularization and vitreous proliferation. Early detection and timely treatment are essential.
RESUMO
Neutrophils are the most abundant leukocytes in the peripheral blood and play an important role in the immune response. However, there is growing evidence indicating that in addition to the immune response, neutrophils also have a crucial role in tumor development, especially in the process of invasion and metastasis. According to current research, depending on their phenotype, neu-trophils appear to be either anti-metastasis (N1) or pro-metastasis (N2). However, the role of tumor-associated neutrophils (TANs) in the metastasis of tumors is relatively complex and lacks a systematic introduction. This review mainly introduces TANs and focuses on the mechanism of TANs in promoting tumor invasion and metastasis. Finally, the possibility of TANs as an anti-tumor treatment strate-gy is discussed.
RESUMO
Acute respiratory distress syndrome (ARDS) can cause pulmonary vascular dysfunction, increase right ventricular afterload and lead to right ventricular failure,also known as acute cor pulmonale. Mechanical ventilation to maintain oxygenation and ventilation has a negative impact on right ventricular function,which may lead to lung-right ventricular interaction and aggravate the deterioration of right ventricu-lar failure,which may be one of the causes of right ventricular failure. Therefore,in the treatment of mechani-cal ventilation for ARDS,attention must be paid to the right ventricular function of patients.
RESUMO
Age-related macular degeneration (AMD) is one of the leading causes to blindness worldwide in elderly population.Innate immune system elements, such as macrophages and cytokines, play an important role in AM D pathology and pathogenesis.In AMD,macrophages can be functionally polarized into M1 (classically activated) and M2 (alternatively activated), as well as regulatory cells, in response to systems biology approaches.Imbalances in the M1 and M2 populations together with activation of retinal microglia are observed and potentially contribute to tissue degeneration.In this review, the phenomenon of macrophage polarization in AMD study was summarized, and the relationship between macrophage polarization and dry AMD,wet AMD,AMD related risk factors were discussed.
RESUMO
Objective To evaluate the efficacy and safety of photodynamic therapy(PDT)combined with intravitreaIinjection of bevacizumab for choroidal neovascularization(CNV)caused by agerelated macular degeneration(AMD). Methods A total of 21 eyes of 21 patients with AMD,which was diagnosed by examination of visual acuity,intraocular pressure,ocular fundus,fundus color photography,fundus fluoreseein angiography(FFA),indocyanine green angiography(ICGA)and optic coherence tomography(OCT),were underwent PDT combined with intravitreal injection of Bevacizumab.The patients,15 males(15 eyes)and 6 females(6 eyes),aged from 56 to 78 years,with the average of 68.6years.The best corrected visual acuity:counting fingers/10cm-0.9,logMAR was 1.04±0.41.CNV located in below or side central fovea of macula.There was obvious leakage of fluorescein which examined by FFA and ICGA.The average of retinal thickness of macular foveal was(258.91±78.66)μm.The treatment method of PDT has to according to the way of PDT for TAP and Verteporfin PDT for VIP.Intravitreal infeetion with 1.5mg bevacizumab was performed after three days under surface anesthesia.Follow-up time was 1,3,6,12 months after the treatment. Resuits At last visit,the best corrected visual acuity:counting fingers/10 cm-1.5,logMAR was 1.04±0.41,and the differences are statistically significant compared with before.The BCVA improved four or more lines in 6 eyes(28.57%),improved two to four lines in 9 eyes(42.86%),stabilized(±1 line or no change)in 6 eyes(28.57%)and decreased in none.The average intraocular pressure was(15.20±2.41)mmHg after surgery,and the differences was not statistically significant compared with before(P＞0.05).FFA and lCGA showed CNV complete closure in 13 eyes(61.90%).partial closure in 8 eyes(38.10%).The average of retinal thickness of macular foveal was(127.38±20.14)μm(P＜0.01). Conclusion Combining treatment with PDT and intravitreal injection of Bevacizumab is safe and effective for CNV which caused by AMD.It has significant improvement in BCVA.1eakage of CNV and retinal edema.
RESUMO
Objective To evaluate the indications, effectiveness and complications of vitreoretinal surgery using the 25G transconjunctival sutureless vitrectomy system (TSV25G) under the topical anesthesia. Methods The clinical and follow-up data of 22 eyes of 22 patients undergone vitreo-retinal surgery using TSV25G under the topical anesthesia were retrospectively analyzed. All of the patients were monocular sickened, including idiopathic macular hole in 10 eyes, idiopathic macular pucker in 6, vitreoretinal traction syndrome in 4, and vitreous hemorrhage associated with branch retinal vein occlusion in 2. Peeling of epiretinal membrane and/or internal limiting membrane, intraocular laser coagulation, air-fluid exchange and tamponiding of C 3F 8 were performed according to the condition of diseases. The postoperative follow-up was 1-11 months, with the mean duration of 6.4 months. The effect of analgesia, cooperation with the patients, operative effect and complications in and after the surgery were observed. Results The operations finished successfully in all of the eyes under the topical anesthesia. The operation duration ranged from 20 to 25 minutes with average of 22 minutes. The patients cooperated with the doctor well without any discomfort. Two days after the surgery, edema of the wounded conjunctiva was found, and recovered 7 days later. A light pigment dot on the surface of the sclera could be seen at the first month. The complications included transient increasing of intraocular pressure in 2 eyes, feather-like opacity of lens in 5 eyes, vitreous hemorrhage in 1 eye, and air-bleb under conjunctiva in 2 eyes. No other complications related with the cut were found. The macular hole closed in 9 eyes with idiopathic macular hole, and the other 1 had the smaller but not closed hole. Idiopathic macular pucker, vitreoretinal traction syndrome, and vitreous hemorrhage associated with branch retinal vein occlusion were cured successfully. Conclusions Vitreoretinal surgery using the TSV25G under the topical anesthesia has many advantages such as simple procedure, short operation time, micro-invasion, less complications and rapid revovery, and mainly serves simple manipulation in some simple diseases such as idiopathic macular hole, vitreo-retinal traction syndrome, and simple hemorrhage.
