AIM: To evaluate the neutrophil-to-lymphocyte ratio(NLR)in patients with retinitis pigmentosa(RP)complicated with cataract, and to explore its correlation with the clinical characteristics of RP patients complicated with cataract.METHODS: The retrospective study included 79 RP patients(125 eyes)complicated with cataract who received cataract surgery at our hospital from January 2008 to December 2018, among which 63 cases(63 eyes)were finally enrolled in the RP complicated with cataract group after the exclusion of patients with early age of onset. Another 63 age- and sex-matched patients(63 eyes)with age-related cataract(ARC)who had cataract surgery during the same period in our hospital were enrolled in the ARC group. The clinical data and NLR were collected, and the correlation of clinical manifestations with NLR in RP patients complicated with cataract was analyzed.RESULTS: The NLR in RP patients complicated with cataract was significantly higher than that in the ARC group [1.79(1.32, 2.27)vs 1.58(1.32, 1.98), P=0.032]. NLR was associated with the severity of posterior subcapsular cataract(PSC), zonular deficiency, and preoperative best-corrected visual acuity(>1 LogMAR). Receiver operating curve showed that NLR ≥1.36 could predict higher degrees(>P1)of RP complicated PSC(AUC=0.803, 95%CI 0.672-0.934, P=0.002), NLR ≥2.12 could predict zonular weakness in RP patients complicated with cataract(AUC=0.796, 95%CI 0.665-0.928, P=0.002), while NLR ≥1.51 could predict RP patients with worse preoperative BCVA(AUC=0.667, 95%CI 0.540-0.793, P=0.015).CONCLUSION: NLR in RP patients complicated with cataract is significantly higher than that in ARC patients, and it is correlated with the clinical manifestations of RP patients with cataract. NLR can be used as a potential predictor to evaluate the severity of clinical manifestations of RP complicated with cataract.

AIM:To observe the clinical efficacy of 3% diquafosol sodium eye drops combined with sodium hyaluronate eye drops in the treatment of dry eyes after pterygium surgery with lacrimal insufficiency.METHODS: A total of 64 cases(64 eyes)of pterygium patients with lacrimal insufficiency were treated with pterygium resection combined with limbal stem cell transplantation, and they were given routine anti-inflammatory and infection prevention treatment postoperatively. In terms of postoperative dry eye treatment, all patients were randomly divided into two groups. The observation group was treated with 3% diquafosol sodium eye drops combined with sodium hyaluronate eye drops, and the control group was treated with sodium hyaluronate eye drops. The break-up time of tear film(BUT), fluorescein(FL), Schirmer's Ⅰ test(SⅠt), ocular surface disease index(OSDI)score, central corneal thickness(CCT)changes, adverse reactions and complications were observed and compared between the two groups at different times postoperatively.RESULTS: Both groups of pterygium patients were accompanied with mild to moderate dry eyes with insufficient tear secretion preoperatively. At 2 wk after operation, both groups showed shorter BUT and higher FL score compared with those preoperatively(P<0.05). There was no significant difference between the two groups(P>0.05). At 4 wk after operation, BUT in the observation group was prolonged, OSDI score was decreased(both P<0.05), and FL score in both groups was decreased compared with those at with 2 wk after operation(P<0.05). The observation group was better than the control group(P<0.05). At the first day after operation, the CCT of the two groups was thicker than that preoperatively(P<0.05), and there was no significant difference in SⅠt between the two groups before and after operation(P>0.05).CONCLUSION: In the treatment of dry eye after pterygium surgery with lacrimal insufficiency, 3% diquafosol sodium eye drops combined with sodium hyaluronate eye drops can effectively reduce the postoperative dry eye symptoms, and its clinical effect is better than that of sodium hyaluronate eye drops alone.

Since the approval of gemtuzumab ozogamicin, an antibody–drug conjugate (ADC) targeting CD33 in 2000, 13 ADC drugs have been approved by the FDA. Although these drugs have clearly improved the survival of patients with various types of advanced cancers, their significant toxicity has compromised their therapeutic benefits. The adverse reactions of ADC drugs are complex and include on-target and off-target toxicities, where the payload drug is a determining factor. Antibody and linker may also affect the degree of toxicity. Combination therapy becomes an important strategy in anticancer treatment because of its increased efficiency, but treatment-related adverse reactions also increase accordingly. This review comprehensively analyzes the toxicity mechanisms of current ADC drugs and proposes various optimization strategies, including but not limited to optimizing linker molecules, upgrading antibody design, and changing drug administration strategies, to improve the overall safety profile of ADC drugs.

Background Hexavalent chromium [Cr(VI)] exposure can cause structural disruption of intestinal flora and functional impairment. Vitamin C (VC) is one of the essential micronutrients, which plays an important role in promoting the growth of intestinal probiotics, improving the intestinal barrier, and maintaining the homeostasis of intestinal flora. However, the regulatory effect of VC on the intestinal flora disorders caused by Cr(VI) exposure remains to be investigated. Objective To investigate the effect of VC on intestinal flora disruption in mice due to Cr(VI) exposure. Methods Thirty-two SPF-grade C57BL/6 mice were acclimatized and fed for 3 d and randomly divided into control (Con), VC, potassium dichromate [K2Cr2O7, Cr(VI)], and VC+K2Cr2O7 [VC+Cr(VI)] groups. At 8:00 a.m. on day 4, the Con group (double-distilled water given by gavage and injected intraperitoneally), the VC group (VC given by gavage and double-distilled water injected intraperitoneally), the Cr(VI) group (double-distilled water given by gavage and K2Cr2O7 solution injected intraperitoneally), and the VC+Cr(VI) group (VC given by gavage and K2Cr2O7 solution injected intraperitoneally) were treated. The dose of VC was 200 mg·kg−1, and the dose of K2Cr2O7 was 1.25 mg·kg−1. The mice were treated for 45 consecutive days and then executed, the contents of the colon were sampled in sterile freezing tubes, and three replicates were collected from each group. After labeling, the samples were immediately put into liquid nitrogen for rapid freezing. After all the samples were collected, they were transferred to a -80 ℃ ultra-low temperature refrigerator for storage. Samples of colon contents were analyzed for intestinal flora structure by high-throughput sequencing and bioinformatics software. Results The Cr(VI) exposure resulted in reduced body weight gain values in mice compared to the Con group. Pathological changes occurred in the ileal tissue of mice, with significant inflammatory cell infiltration in the Cr(VI) group and reduced inflammatory cell infiltration in the VC+Cr(VI) group. The number of operational taxonomic units (OTUs) of intestinal flora was altered in the Cr(VI) group of mice. In the α diversity analysis, the mean Sobs index in the Cr(VI) group was 240.333±67.796, the Chao index was 258.173±64.813, and the Ace index was 259.481±66.891, which were significantly lower than those in the Con group (P<0.05), the PD whole tree index in the Cr(VI) group was 27.863±2.399, which was significantly higher than that in the Con group (P<0.05), and the VC intervention significantly reversed the changes of the above indexes due to Cr(VI) exposure (P<0.05). In the β diversity analysis, the principal coordinates analysis (PCoA) results showed a significant separation between the Cr(VI) group and the Con group, and after the VC intervention, there was a retraction of the separation trend and the difference was reduced. The multi-sample similarity dendrogram results showed that the control and the VC groups clustered together first, then with the VC+Cr(VI) group, and finally with the Cr(VI) group. The abundances of Bacteroidetes, Saccharibacteria, and Tenericutes in the intestine of mice in the Cr(VI) group were decreased, and the abundance of Firmicutes was increased; the abundances of Lactobacillus, Alistipes, Bacteroides, and Ruminiclostridium were also increased. Included among these, Bacteroides showed a significantly higher abundance compared to the control mice (P<0.05). Changes in the abundances of phyla and genera of the above mentioned gut microorganisms were reversed after the VC intervention. Conclusion Cr(VI) exposure can lead to intestinal damage and disorganization of the intestinal flora structure in mice, while VC intervention can ameliorate the above changes to a certain extent and normalize the intestinal flora structure.

BACKGROUND:Due to the mismatch between the design of the proximal femoral nail antirotation Asian version(PFNA-Ⅱ)and Asian population,extrusion of the proximal femoral intertrochanteric nail may occur in the treatment of femoral intertrochanteric fractures.The influence of the protruding length on the curative effect of the operation needs to be further discussed. OBJECTIVE:To quantitatively measure the protruding length of the proximal trochanter of the femur with intramedullary nail after PFNA-Ⅱ,and to analyze the effect of protruding length on the efficacy of PFNA-Ⅱ in the treatment of femoral intertrochanteric fractures. METHODS:Totally 68 patients with femoral intertrochanteric fractures treated with PFNA-Ⅱ internal fixation in the First Affiliated Hospital of Anhui Medical University were selected.The extramedullary process of the proximal trochanter of the femur was quantitatively measured on the anterior and posterior X-ray films of the hip joint within 6 months after operation.According to the existence of extrusion of the proximal trochanter intramedullary nail,the patients were divided into protruding group and non-protruding group.The data of sex,height,fracture type,length and diameter of the intramedullary nail,the position of screw blade in the femoral neck and protruding length of proximal greater trochanter were collected.The postoperative curative effect was judged by visual analog scale pain score and hip joint Harris score at 6 months after operation.The influence of protruding proximal trochanter of the PFNA-Ⅱ intramedullary nail on the operative effect was observed. RESULTS AND CONCLUSION:(1)There were significant differences in sexual characteristics between the protruding group and the non-protruding group(P=0.001).(2)According to AO/OTA classification,there were no significant differences in fracture type between the protruding group and the non-protruding group(P=0.289).(3)There was no significant difference in the length and diameter of the intramedullary nail between the two groups(P=0.067,P=1.000).(4)There was no significant correlation between the height of all patients and the length of the intramedullary nail(P=0.510),but there was a significant correlation between height and protruding length(P=0.034).There was no significant correlation between screw blade position and protruding length(P=0.968).(5)Six months after operation,there was no significant difference in the hip Harris score(P=0.373),but the visual analog scale pain score was significantly higher in the protruding group than that in the non-protruding group(P=0.000).(6)The results suggest that nail extrusion often occurs in the proximal greater trochanter when PFNA-Ⅱ is used in the treatment of intertrochanteric fractures in Asians.When the nail extended into the proximal soft tissue of the greater trochanter,patients complained of proximal greater trochanteric pain and the visual analog scale score of proximal greater trochanter pain in the patient was significantly higher than that in the non-protruding group.To be more suitable for the Asian population,we suggest that the PFNA-Ⅱ should be improved to further shorten the proximal nail end to obtain better clinical results of femoral intertrochanteric fracture fixation.

@#Objective To explore the reliability and safety of continuous monitoring of vital signs in patients using wireless wearable monitoring devices after video-assisted thoracoscopic surgery (VATS) for lung cancer. Methods The patients undergoing VATS for lung cancer in West China Hospital, Sichuan University from May to August 2023 were prospectively enrolled. Both wireless wearable and traditional wired devices were used to monitor the vital signs of patients after surgery. Spearman correlation analysis, paired sample t test and ratio Bland-Altman method were used to test the correlation, difference and consistency of monitoring data measured by the two devices. The effective monitoring rate of the wireless wearable device within 12 hours was calculated to test the reliability of its continuous monitoring. Results A total of 20 patients were enrolled, including 15 females and 5 males with an average age of 46.20±11.52 years. Data collected by the two monitoring devices were significantly correlated (P<0.001). Respiratory rate and blood oxygen saturation data collected by the two devices showed no statistical difference (P>0.05), while heart rate measured by wireless wearable device was slightly lower (=−0.307±1.073, P<0.001), and the blood pressure (=1.259±5.354, P<0.001) and body temperature(=0.115±0.231, P<0.001) were slightly higher. The mean ratios of heart rate, respiratory rate, blood oxygen saturation, blood pressure and body temperature collected by the two devices were 0.996, 1.004, 1.000, 1.014, and 1.003, respectively. The 95% limits of agreement (LoA) and 95% confidence interval of 95%LoA of each indicator were within the clinically acceptable limit. The effective monitoring rate of each vital signs within 12 hours was above 98%. Conclusion The wireless wearable device has a high accuracy and reliability for continuous monitoring vital signs of patients after VATS for lung cancer, which provides a security guarantee for subsequent large-scale clinical application and further research.

OBJECTIVE@#To explore the feasibility and effectiveness of a foldable pedicled latissimus dorsi myocutaneous flap to repair soft tissue defects in the shoulder and back.@*METHODS@#Between August 2018 and January 2023, the foldable pedicled latissimus dorsi myocutaneous flaps were used to repair soft tissue defects in the shoulder and back of 8 patients. There were 5 males and 3 females with the age ranged from 21 to 56 years (mean, 35.4 years). Wounds were located in the shoulder in 2 cases and in the shoulder and back in 6 cases. The causes of injury were chronic infection of skin and bone exposure in 2 cases, secondary wound after extensive resection of skin and soft tissue tumor in 4 cases, and wound formation caused by traffic accident in 2 cases. Skin defect areas ranged from 14 cm×13 cm to 20 cm×16 cm. The disease duration ranged from 12 days to 1 year (median, 6.6 months). A pedicled latissimus dorsi myocutaneous flap was designed and harvested. The flap was divided into A/B flap and then were folded to repair the wound, with the donor area of the flap being pulled and sutured in one stage.@*RESULTS@#All 7 flaps survived, with primary wound healing. One patient suffered from distal flap necrosis and delayed healing was achieved after dressing change. The incisions of all donor sites healed by first intention. All patients were followed up 6 months to 4 years (mean, 24.7 months). The skin flap has a good appearance with no swelling in the pedicle. At last follow-up, 6 patients had no significant difference in bilateral shoulder joint motion, and 2 patients had a slight decrease in abduction range of motion compared with the healthy side. The patients' daily life were not affected, and linear scar was left in the donor site.@*CONCLUSION@#The foldable pedicled latissimus dorsi myocutaneous flap is an ideal method to repair the soft tissue defect of shoulder and back with simple operation, less damage to the donor site, and quick recovery after operation.

AIM: To compare the efficacy of Jensen and augmented Hummelsheim procedures in the treatment of complete paralytic esotropia.METHOD: A total of 35 patients(44 eyes)who were diagnosed with complete paralytic esotropia from October 2016 to October 2020 were retrospectively analyzed, of which 15 cases(21 eyes)underwent Jensen procedure combined with recession of antagonist muscle(Jensen procedure group), and 20 cases(23 eyes)received augmented Hummelsheim procedure combined with recession of antagonist muscle(Hummelsheim procedure group). The operation time, preoperative and postoperative esotropia deviation, degree of abduction paralysis, recession of medial rectus muscle and cure rate were observed.RESULTS: Clinical data and operation time of the patients in two groups were not statistically significant(P &#x003E;0.05). During the last follow-up, the esotropia deviation of Jensen procedure group decreased from 102.33±41.70PD to 3.93±4.82PD(P&#x003C;0.001), and it decreased from 94.75±33.03PD to 2.85±5.96PD in Hummelsheim procedure group(P&#x003C;0.001), while the degree of abduction paralysis were significantly improved from -4.81±0.40 to -1.57±0.51 in the Jensen procedure group(P&#x003C;0.001)and from -4.91±0.29 to -1.22±0.42 in Hummelsheim procedure group(P&#x003C;0.001). Besides, there was no statistical difference in postoperative esotropia deviation between the two groups(P&#x003E;0.05), but the degree of postoperative abduction paralysis in the Hummelsheim procedure group was significantly better than that of Jensen procedure group(P&#x003C;0.05). The recession of medial rectus muscle of the two groups were 7.16±2.07 and 6.37±2.34 mm, respectively(P&#x003E;0.05). During the last follow-up, in the Jensen procedure group, 2 patients were undercorrection(+10PD and +12PD respectively)and 13 cases(87%)were cured. In the Hummelsheim procedure group, 1 patient was undercorrection(+25PD)and 19 patients were cured(95%), and there was no statistical significance in cure rates of the two groups(P=0.565).CONCLUSIONS: Both Jensen procedure and augmented Hummelsheim procedure can effectively treat complete paralytic esotropia, and the latter is more effective in improving the abduction paralysis.

Objective:To investigate the effect and molecular mechanism of tumor necrosis factor-α-inducible protein 8-like 2(TIPE2)on lipopolysaccharide(LPS)or interleukin-4(IL-4)-induced phenotypic switch of adipose tissue macrophages(ATM).Methods:The expression levels of TIPE2, inducible nitric oxide synthase(iNOS), monocyte chemoattractant protein 1(MCP-1), CD206, and arginase 1(Arg-1)in the visceral adipose tissue of obese mice, TIPE2-knockout(KO)mice, and control mice were detected by immunohistochemistry, Western blotting, and real-time PCR(RT-qPCR). Peritoneal macrophages isolated from KO and wild-type mice and RAW 264.7 mouse macrophage cell line were cultured, and then stimulated with LPS(100 ng/mL)or IL-4(20 ng/mL)for 6 hours. The expression levels of TIPE2, iNOS, MCP-1, CD206, and Arg-1 were detected by Western blotting and RT-qPCR.Results:Obese mice showed down-regulated TIPE2 expression, up-regulated pro-inflammatory markers iNOS and MCP-1 expressions, and down-regulated anti-inflammatory markers CD206 and Arg-1 expressions. LPS decreased the expression of TIPE2 in RAW 264.7 cells and peritoneal macrophages from mice, increased the expression of the classically activated macrophages(M1 phenotype)markers iNOS and MCP-1, and decreased the expression of the substituting activated macrophages(M2 phenotype)markers CD206 and Arg-1. IL-4 increased the expression of TIPE2 in RAW 264.7 cells and peritoneal macrophages, decreased the expression of iNOS and MCP-1, and increased the expression of CD206 and Arg-1. During the M1 polarization of macrophages, LPS increased toll-like receptor(TLR4)expression as well as nuclear transcription factor κBα suppressor protein(IκBα) and NF-κB phosphorylations in macrophages. Knockout of TIPE2 further increased the expression of the TLR4/IκBα/NF-κB signaling pathway and M1 macrophage markers, and further reduced the expression of the M2 macrophage markers.Conclusion:TIPE2 regulates ATM phenotypic transformation through inhibition of the TLR4/IκBα/NF-κB signaling pathway, which ameliorates adipose tissue inflammation in obese states.

Objective:To evaluate the efficacy and safety of quadruple therapy involving radiotherapy (RT), lenvatinib, anti-PD-1 antibody and GEMOX (oxaliplatin and gemcitabine) chemotherapy (quadruple therapy) in treatment cohort of patients with unresectable intrahepatic cholangiocarcinoma (ICC).Methods:The patients with recurrent, metastatic, or unresectable ICC underwent quadruple therapy at Zhongshan Hospital, Fudan University between September 2018 and May 2022 were selected. The data about efficacy and safety of quadruple therapy were collected in the hospital electronic medical record system. All patients were followed up regularly to obtain the long-term prognostic data until December 31, 2022. The efficacy, prognosis, and toxicity data were collected and analyzed.Results:A total of 41 patients were included in the analysis. After a median follow-up period of 15 months, disease progression was diagnosed in 36 patients (18 patients died), while 3 patients were lost to follow-up. The causes of death included liver failure induced by intrahepatic tumor progression ( n=6), distant metastases (lungs or brain, n=6), abdominal lymph node metastases ( n=3), cancer cachexia ( n=2), and unknown cause ( n=1). The median progression-free survival (PFS) was 11 months (95% CI: 9.2-12.8), and the median overall survival (OS) was 35 months (95% CI: 17.0-52.0). All patients experienced treatment-related adverse events (AEs) during the study treatment period. Of the 41 patients, 13 patients experienced at least once grade 3 or worse treatment-related AE, but all were manageable with symptomatic treatment. No treatment-related deaths were reported during the follow-up period. Conclusions:Radiotherapy (RT), lenvatinib, anti-PD-1 antibody and GEMOX in the treatment of unresectable ICC shows significant efficacy and good safety, which is worthy of clinical application.

Objective:To evaluate and compare the efficacy and safety of ultra-rapid lispro insulin (URLi) and humalog lispro (HL) in the treatment of type 2 diabetes mellitus.Methods:This was an international multicenter, double-blind, randomized controlled study. From May 2019 to January 2021, a total of 481 patients with type 2 diabetes mellitus, who had been using insulin for at least 90 days and had poor glycemic control, were included. These patients were recruited from 34 research centers in China, including Shanghai Jiao Tong University School of Medicine Affiliated Sixth People′s Hospital. They were assigned to either the URLi group (319 patients) or the HL group (162 patients) using stratified blocked randomization. The primary endpoint was the change in hemoglobin A 1c (HbA 1c) relative to baseline after 26 weeks of treatment. Secondary endpoints included the proportion of patients who achieved HbA 1c<7.0% and ≤6.5% after 26 weeks of treatment, 1-h postprandial glucose (1hPG) or 2-h postprandial glucose (2hPG) excursions during a mixed meal tolerance test at week 26, as well as safety parameters. Continuous variables were compared using mixed model repeated measures or analysis of covariance, and categorical variables were compared using logistic regression or Fisher′s exact test. Results:Data based on the Chinese subgroup showed that there were no statistically significant differences between the URLi and HL groups in terms of male percentage [56.1% (179/319) vs. 56.2% (91/162); P=0.990], age [(59.5±8.4) vs. (59.6±9.3) years; P=0.839] and other baseline characteristics. Regarding the change in HbA 1c relative to baseline, the URLi group was non-inferior to the HL group (-0.59%±0.05% vs. -0.66%±0.06%; P=0.312). There were no statistically significant differences between the URLi and HL groups in proportion of patients who achieved HbA 1c<7.0% [47.3% (138/292) vs. 45.2% (70/155); P=0.907] and≤6.5% [27.7% (81/292) vs. 27.7% (43/155); P=0.816]. The excursions in 1hPG [(6.20±0.21) vs. (6.90±0.25) mmol/L; P=0.001] and 2hPG [(8.10±0.27) vs. (9.30±0.31) mmol/L; P<0.001] were lower in the URLi group than the HL group, with statistically significant differences. In terms of safety, there were no statistically significant differences in the percentage of subjects who reported treatment-emergent adverse events between the URLi and HL groups [49.8% (159/319) vs. 50.0% (81/162); P=1.000]. The event rate of nocturnal hypoglycemia was lower in the URLi group than the HL group, with statistically significant differences [(0.53±0.10) vs. (0.89±0.16) events per patient -year; P=0.040]. Conclusions:With good glycemic control, URLi showed non-inferiority for HbA 1c improvement versus HL and was superior to HL for postprandial glucose excursion control. Meanwhile the rate and incidence of nocturnal hypoglycemia were lower in the URLi group than the HL group.

Objective:To evaluate clinical efficacy and safety of secukinumab in the treatment of patients with localized pustular psoriasis irresponsive or intolerant to conventional treatment.Methods:Clinical data were collected from 13 patients with refractory localized pustular psoriasis, who received secukinumab treatment in Department of Dermatology, Xijing Hospital from December 2019 to April 2022. Efficacy was evaluated by comparing palmoplantar pustulosis (PPP) area and severity index (PPPASI) score and physician global assessment (PGA) score in PPP patients before and after the treatment, and by comparing clinical global impression (CGI) score in patients with acrodermatitis continua of Hallopeau (ACH). Adverse events were recorded during the treatment.Results:Among the 13 patients with refractory localized pustular psoriasis, 6 were diagnosed with PPP, 3 with ACH, and 4 with PPP complicated by ACH. There were 3 males and 10 females, and their age was 33.2 ± 14.6 years. After 12-week treatment, the PPPASI score decreased from 13.88 ± 3.62 points at baseline to 6.81 ± 2.31 points in 10 patients presenting with PPP lesions, 4 achieved 75% improvement in the PPPASI score (PPPASI75), and 5 achieved PGA0/1; at the same time, 6 of the 7 patients presenting with ACH lesions achieved moderate or marked improvement in the CGI score, and 4 of the 6 patients achieved marked improvement. Two patients with PPP discontinued the treatment after 3- and 5-week treatment respectively due to poor response, and 1 patient with ACH achieved mild improvement in the CGI score after 12-week treatment. No severe adverse events were reported during the treatment. However, inflammatory follicular papules occurred in 1 patient, and eczematoid lesions occurred in another 1 patient, which both regressed after symptomatic treatment.Conclusion:Secukinumab was effective and safe in the treatment of refractory localized pustular psoriasis, and may serve as a new treatment option for refractory PPP and ACH.

@#Aortic dissection is one of the most devastating cardiovascular diseases. One of the most important pathological features of aortic dissection is local inflammatory response, including the infiltration of inflammatory cells, extracellular matrix degradation, and smooth muscle cell phenotype switch. Macrophages which are the core of the inflammatory response play an extremely pivotal role in the progression of inflammation and tissue remodeling. Macrophages can be artificially divided into M1 and M2 types, of which the M1-type promotes inflammation while the M2-type is associated with the regression of inflammation and tissue healing. Mastering the switch of phenotypic transformation of macrophages may be of great help in inhibiting the inflammation of aortic tissue and facilitating tissue healing, as well as the treatment of aortic dissection. In this paper, we focus on the polarization of macrophages and discuss the role of macrophages in aortic dissection, the polarization pathway and the effect of related polarizing agents on the treatment of aortic dissection.
