RESUMO

BACKGROUND: Fecal incontinence has a devastating impact on quality of life and imposes a substantial socioeconomic burden. Best medical therapy including biofeedback therapy improves mild symptoms, with minimal impact on moderate to severe symptoms. Surgical management for incontinence carries a degree of morbidity resulting in low uptake and acceptability. While acupuncture is common practice in Singapore for numerous medical conditions, its role in fecal incontinence is relatively novel. In our local context, however, acupuncture is accessible, inexpensive, and potentially well-accepted as a treatment strategy. OBJECTIVE: To determine the effectiveness of Traditional Chinese Medicine acupuncture, compared to biofeedback therapy in the treatment of fecal incontinence. The secondary aim is to investigate the differences in quality of life following treatment. DESIGN: Randomized controlled trial. SETTING: Prospective, single institution study. PATIENTS: Patients with ≥2 episodes of fecal incontinence/week, or St Mark's incontinence score of ≥5 were recruited. Patients were randomized into biofeedback therapy which included 3 sessions over 10 weeks, or 30 sessions of acupuncture over 10 weeks. MAIN OUTCOME MEASURES: Incontinence episodes, St. Mark's Score and Fecal Incontinence Quality of Life scale. RESULTS: Eighty-five patients were randomized into biofeedback therapy (n=46) or acupuncture (n = 39). Demographics and baseline clinical characteristics were not different (p > 0.05). Overall median incontinence episodes were reduced in both, with the acupuncture arm reporting significantly fewer at week 15 (p < 0.001). Acupuncture also improved quality of life, with improvement in lifestyle, coping, depression, and embarrassment at week 15 (p < 0.05). While the St. Mark's score was significantly reduced in both arms at week 15 (p < 0.001), the acupuncture arm's score was significantly lower (p = 0.002). LIMITATIONS: Longer follow-up required. CONCLUSIONS: Acupuncture is clinically effective and improves quality of life in patients with fecal incontinence. See Video Abstract. CLINICAL TRIAL REGISTRATION: Clinicaltrials.gov: NCT04276350.

RESUMO

Porcine epidemic diarrhea virus (PEDV) is one of the most devastating diseases affecting the pig industry globally. Due to the emergence of novel strains, no effective vaccines are available for prevention and control. Investigating the pathogenic mechanisms of PEDV may provide insights for creating clinical interventions. This study constructed and expressed eukaryotic expression vectors containing PEDV proteins (except NSP11) with a 3' HA tag in Vero cells. The subcellular localization of PEDV proteins was examined using endogenous protein antibodies to investigate their involvement in the viral life cycle, including endocytosis, intracellular trafficking, genome replication, energy metabolism, budding, and release. We systematically analyzed the potential roles of all PEDV viral proteins in the virus life cycle. We found that the endosome sorting complex required for transport (ESCRT) machinery may be involved in the replication and budding processes of PEDV. Our study provides insight into the molecular mechanisms underlying PEDV infection. IMPORTANCE: The global swine industry has suffered immense losses due to the spread of PEDV. Currently, there are no effective vaccines available for clinical protection. Exploring the pathogenic mechanisms of PEDV may provide valuable insights for clinical interventions. This study investigated the involvement of viral proteins in various stages of the PEDV lifecycle in the state of viral infection and identified several previously unreported interactions between viral and host proteins. These findings contribute to a better understanding of the pathogenic mechanisms underlying PEDV infection and may serve as a basis for further research and development of therapeutic strategies.

RESUMO

Estuarine wetlands exhibit significant interaction between fresh and salt water, with long-term carbon sequestration capability. We set up 60 sampling sites in the reed wetlands of the fresh-salt water interaction zone of the Yellow River Estuary, covering four different zones of the weak-intensity fresh-salt water interaction zone (WIZ), medium-intensity fresh-salt water interaction zone (MIZ), high-intensity interaction fresh-salt water zone (HIZ) and strong-intensity fresh-salt water interaction zone (SIZ). We investigated how fresh-salt water interaction affected the spatial variation of soil organic carbon (SOC) storage. The results showed that the area of reed wetland accounted for 17.8% of the total area of the fresh-salt water interaction zone the Yellow River Estuary, which mainly distributed in the WIZ and MIZ. The SOC content of reed wetland in the fresh-salt water interaction zone ranged from 1.09 to 3.65 g·kg-1, the SOC density was between 1.85-5.84 kg·m-2, and the SOC storage was (17.32±3.64)×104 t. The SOC content and SOC density decreased with increasing fresh-salt water interaction. There were significant differences in surface SOC content between different subzones of the fresh-salt water interaction zone. The surface SOC content decreased significantly with the increases of fresh-salt water interaction intensity. SOC density was positively correlated with SOC, TN, NH4+-N, and biomass, but negatively correlated with salt ions, soil bulk density, pH, and EC. SOC storage in the 0-30 cm soil layer accounted for 50.9%-64.2% of that in the 0-60 cm soil layer, while SOC storage in the 0-60 cm soil layer occupied 19.1%-37.7% of that in the 0-400 cm soil layer. The results could provide a scientific basis for accurately evaluating SOC storage of estuarine wetlands, improving carbon sink function and wetland management.

RESUMO

BACKGROUND: Uncomplicated urinary tract infections (uUTIs) are one of the most common community-acquired infections, particularly among women. Common symptoms of UTI include dysuria, urinary urgency and increased frequency, and lower abdominal pain. With appropriate treatment, symptoms may resolve in a few days. However, there is a lack of research on the emotional impact of this disease. We conducted a qualitative, interview-based study to gain a greater understanding of the emotional impact of uUTIs in women in China and Japan. METHODS: A qualitative, exploratory, in-depth, interview-based study was conducted between 19 November 2020 and 25 February 2021. Women aged ≥ 18 years who experienced ≥ 1 uUTI and received antibiotic treatment in the past year were eligible for inclusion. Participants must have experienced ≥ 1 of the following symptoms during a uUTI episode: urinary urgency, frequency, dysuria, or lower abdominal/suprapubic pain. Participants who reported back pain or fever (indicative of complicated UTI) were excluded. Participants with recurrent or sporadic UTIs were included, with specific screening criteria used to ensure capture of both groups. Following a screening call, a structured, in-depth telephone interview (~ 30 min in duration) was conducted by three female external moderators trained in qualitative interviewing, assisted by an interview guide. Interviews were analysed individually and thematically, with the results presented within the identified themes. RESULTS: A total of 65 women with uUTI completed the in-depth telephone interview: 40 (62%) from China and 25 (38%) from Japan. Participants reported that the symptoms of uUTI affected multiple aspects of their lives, and described feelings of embarrassment, frustration, guilt, dread, and loneliness associated with symptoms that interfered with relationships, work and daily activities, and sleep. Participants reported seeking healthcare from several different points of contact, from local pharmacies to hospitals. CONCLUSIONS: Our analysis highlights the profound emotional impact of uUTIs in women in China and Japan, and the journey these participants take before their initial interaction with a healthcare professional. These insights emphasise the need to better understand the full impact of uUTI, and the role of healthcare professionals in improved patient education and support.

RESUMO

OBJECTIVE: The aims of the study were first to explore the adaptive leisure activities of classified nursing model from the perspective of nurse-patient interactive care, and to explore its impact on the physical and mental health of patients with colon cancer. METHODS: From September 2017 to March 2022 as the observation time node, 82 patients with colon cancer who met the established inclusion and exclusion criteria were regarded as the research objects through the random number table as the grouping tool. The two groups of patients were named as the research group and the control group, with 41 patients in each group. The control group implemented routine nursing measures, and the research group implemented classified nursing mode and adaptive leisure activity mode. The two groups of patients received 4 weeks of nursing intervention. With the help of self-rating anxiety scale, self-rating depression scale, self-care ability evaluation scale and health status survey brief form, the two groups of patients were compared before intervention and at the end of the 4th week after intervention. RESULTS: After the intervention, the anxiety score (t = 6.656, p < 0.001) and depression score (t = 4.851, p < 0.001) of the research group were lower than those of the control group, and the difference was statistically significant. After the intervention, the self-concept (t = 4.845, p < 0.001), self-responsibility (t = 6.071, p < 0.001), self-care skills (t = 3.341, p < 0.001), health knowledge (t = 3.698, p < 0.001) and total score (t = 9.246, p < 0.001) of the research group were higher than those of the control group, and the difference was statistically significant. After the intervention, physical functioning (t = 8.141, p < 0.001), bodily pain (t = 6.083, p < 0.001), general health (t = 9.424, p < 0.001), role-physical (t = 8.057, p < 0.001), role-emotional (t = 13.252, p < 0.001), mental health (t = 12.565, p < 0.001), social functioning (t = 10.813, p < 0.001) and vitality score (t = 12.890, p < 0.001) of the research group were higher than those of the control group, with significant differences. CONCLUSION: Interactive care through adaptive leisure nursing improves mental well-being, self-management, and psychosocial functioning in elderly colon cancer patients, promoting overall health.

RESUMO

The merger of electrochemistry and transition metal catalysis has emerged as a powerful tool to join two electrophiles in an enantioselective manner. However, the development of enantioselective electroreductive cross-couplings of olefins remains a challenge. Inspired by the advantages of the synergistic use of electrochemistry with nickel catalysis, we present here a Ni-catalyzed enantioselective electroreductive cross-coupling of acrylates with aryl halides and alkyl bromides, which affords chiral α-aryl carbonyls in good to excellent enantioselectivity. Additionally, this catalytic reaction can be applied to (hetero)aryl chlorides, which is difficult to achieve by other methods. The combination of cyclic voltammetry analysis with electrode potential studies suggests that the NiI species activates aryl halides by oxidative addition and alkyl bromides by single-electron transfer.

RESUMO

BACKGROUND: Although previous findings with small samples indicated that sugar-sweetened beverages (SSB) consumption was associated with depressive symptoms in adolescents, the mediating effect of physical sub-health in the association is unknown. METHODS: A survey was conducted among freshmen from 11 provinces in China. A food frequency questionnaire was used to collect dietary behavior, and patient health questionnaire-9 items was used to assess depressive symptoms. A generalized linear model was used to analyze the association between SSB consumption, physical sub-health and depressive symptoms. The structural equation model was used to analyze the mediating effect of physical sub-health. RESULTS: Of the 31,856 participants, 36.5 % had positive depressive symptoms. After adjusting for variables, carbonate beverages (ß = 0.11; 95%CI: 0.07-0.15; P = 0.000) and milk tea (ß = 0.07; 95%CI: 0.01-0.13; P = 0.021) consumption was associated with depressive symptoms in boys. Carbonate beverages (ß = 0.09; 95%CI: 0.05-0.13; P = 0.000), tea beverages (ß = 0.09; 95%CI: 0.04-0.13; P = 0.000), and milk tea (ß = 0.08; 95%CI: 0.04-0.11; P = 0.000) consumption was associated with depressive symptoms in girls. The mediating effect of physical sub-health accounted for 81.3 % of the total effect in the mediating model of SSB associated with depressive symptoms. LIMITATIONS: Retrospective survey has certain information bias. Association observed in the cross-sectional study is uncertain. CONCLUSIONS: The present study suggests that the consumption of SSB associated with depressive symptoms in Chinese college students, and physical sub-health plays a complete mediating role in the association.

RESUMO

Carbon (C), nitrogen (N), and phosphorus (P) are important nutrients, and their ecological stoichiometric characteristics can reflect the quality and fertility capacity of soil, which is critical to understanding the stable mechanisms of estuarine wetland ecosystems. Under global changes, the increase in salinity and flooding caused by sea level rise will lead to changes in biogeochemical processes in estuarine wetlands, which is expected to affect the ecological stoichiometric characteristics of soil C, N, and P and ultimately interfere with the stability of wetland ecosystems. However, it remains unclear how the C, N, and P ecological stoichiometric characteristics respond to the water-salt environment in estuarine wetlands. We differentiated changes in the C, N, and P ecological stoichiometric characteristics through an ex-situ culture experiment for 23 months in the Yellow River Estuary Wetland. The five sites with distinct tidal hydrology were selected to manipulate translocation of soil cores from the freshwater marsh to high-, middle-, and low-tidal flats in June 2019. The results showed that soil water content (SWC); electrical conductivity (EC); and C, N, and P ecological stoichiometric characteristics of freshwater marsh soil significantly changed after translocation for 23 months. SWC decreased on the high- and middle-tidal flats (P<0.05) and increased on the low-tidal flat (P<0.05). EC increased to different degrees on all three tidal flats (P<0.05). Soil total organic carbon (TOC) and total nitrogen (TN) were significantly lower on the high-tidal flat (P<0.05), whereas total phosphorus (TP) was significantly lower on the middle- and high-tidal flats (P<0.05). C:N was decreased on the high- and middle-tidal flats (P<0.05); C:P and N:P were lower on the high-tidal flat; and all C, N, and P ecological stoichiometric characteristics showed no change on the low-tidal flat (P>0.05). Pearson's analysis showed that the ecological stoichiometric characteristics of C, N, and P were related to some properties of soil over the culture sites. The PLS-SEM model showed that the water-salt environment had different effects on soil C:N, C:P, and N:P through the main pathways of negative effects on soil TOC and TP. The results suggest that sea level rise may impact the C, N, and P ecological stoichiometric characteristics in freshwater marsh soil, resulting in some possible changes in the nutrient cycles of estuarine wetlands.

RESUMO

Metal-catalyzed asymmetric electro-reductive couplings have emerged as a powerful tool for organic synthesis, wherein a sacrificial anode is typically required. Herein, a parallel paired electrolysis (PPE)-enabled asymmetric catalysis has been developed, and the alcohols and ketones could be simultaneously converted to the corresponding aldehydes and chiral tertiary alcohols with high yields and enantioselectivity in an undivided cell. Additionally, this Ni-catalyzed asymmetric reductive coupling can well match the anodic oxidative C-H bond bromination of (hetero)arenes. This protocol opens an alternative avenue for organic synthesis.

RESUMO

Colletotrichum gloeosporioides, a significant fungal pathogen of crops and trees, causes large economic losses worldwide. However, its pathogenic mechanism remains totally unclear. In this study, four Ena ATPases (Exitus natru-type adenosine triphosphatases), homology of yeast Ena proteins, were identified in C. gloeosporioides. Gene deletion mutants of ΔCgena1, ΔCgena2, ΔCgena3, and ΔCgena4 were obtained through the method of gene replacement. First, a subcellular localization pattern indicated that CgEna1 and CgEna4 were localized in the plasma membrane, while the CgEna2 and CgEna3 were distributed in the endoparasitic reticulum. Next, it was found that CgEna1 and CgEna4 were required for sodium accumulation in C. gloeosporioides. CgEna3 was required for extracellular ion stress of sodium and potassium. CgEna1 and CgEna3 were involved in conidial germination, appressorium formation, invasive hyphal development, and full virulence. The mutant of ΔCgena4 was more sensitive to the conditions of high concentrations of ion and the alkaline. Together, these results indicated that CgEna ATPase proteins have distinct roles in sodium accumulation, stress resistance, and full virulence in C. gloeosporioides.

RESUMO

Acne vulgaris is a common skin condition that affects a large proportion of teenagers and young adults. Despite the availability of various treatment options, many patients experience inadequate relief or intolerable side effects. Photodynamic therapy (PDT) is a growing interest in the treatment of acne vulgaris, with 5-Aminolaevulinic acid (ALA) being one of the most commonly used photosensitizers. Adalimumab is a biologic medication used to treat inflammatory skin conditions such as Psoriasis and Hidradenitis suppurativa (HS), which targets TNF-α. Combining different therapies, such as ALA-PDT and adalimumab, can often provide more effective and longer-lasting results. This report presents the case of a patient with severe and refractory acne vulgaris who was treated with a combination of ALA-PDT and adalimumab, resulting in significant improvement in the condition. The literature review highlights the significant comorbidity associated with acne, emphasizing the need for potential of TNF-α inhibitors for its effective treatments that address physical symptoms and ALA-PDT is known to treat scar hyperplasia, and to prevent or minimize the formation of post-acne hypertrophic scars. The combination of TNF inhibitors and ALA-PDT or adalimumab has shown promising results in treating inflammatory skin conditions, including severe and refractory acne vulgaris, as per recent studies.

RESUMO

Here, we report an asymmetric electrochemical organonickel-catalyzed reductive cross-coupling of aryl aziridines with aryl iodides in an undivided cell, affording ß-phenethylamines in good to excellent enantioselectivity with broad functional group tolerance. The combination of cyclic voltammetry analysis of the catalyst reduction potential as well as an electrode potential study provides a convenient route for reaction optimization. Overall, the high efficiency of this method is credited to the electroreduction-mediated turnover of the nickel catalyst instead of a metal reductant-mediated turnover. Mechanistic studies suggest a radical pathway is involved in the ring opening of aziridines. The statistical analysis serves to compare the different design requirements for photochemically and electrochemically mediated reactions under this type of mechanistic manifold.

RESUMO

We report high-power multi-junction vertical-cavity surface-emitting lasers (VCSELs) with a significantly suppressed carrier leakage issue under high injection current and temperature. By carefully optimizing the energy band structure of quaternary AlGaAsSb, we obtained a 12-nm-thick AlGaAsSb electron-blocking layer (EBL) with a high effective barrier height (∼122 meV), a low compressive strain (∼0.99%), and a reduced electronic leakage current. The resulting three-junction (3J) 905 nm VCSEL with the proposed EBL exhibits an improved maximum output power (∼46.4 mW) and power conversion efficiency (PCE; ∼55.4%) during room-temperature operation. Also, it was found from thermal simulation that the optimized device shows more advantages over the original device during high-temperature operation. The type-II AlGaAsSb EBL provided an excellent electron-blocking effect and would be a promising strategy for multi-junction VCSELs to realize high-power applications.

RESUMO

Porcine enteric alphacoronavirus (PEAV) is a new bat HKU2-like porcine coronavirus, and its endemic outbreak has caused severe economic losses to the pig industry. Its broad cellular tropism suggests a potential risk of cross-species transmission. A limited understanding of PEAV entry mechanisms may hinder a rapid response to potential outbreaks. This study analyzed PEAV entry events using chemical inhibitors, RNA interference, and dominant-negative mutants. PEAV entry into Vero cells depended on three endocytic pathways: caveolae, clathrin, and macropinocytosis. Endocytosis requires dynamin, cholesterol, and a low pH. Rab5, Rab7, and Rab9 GTPases (but not Rab11) regulate PEAV endocytosis. PEAV particles colocalize with EEA1, Rab5, Rab7, Rab9, and Lamp-1, suggesting that PEAV translocates into early endosomes after internalization, and Rab5, Rab7, and Rab9 regulate trafficking to lysosomes before viral genome release. PEAV enters porcine intestinal cells (IPI-2I) through the same endocytic pathway, suggesting that PEAV may enter various cells through multiple endocytic pathways. This study provides new insights into the PEAV life cycle. IMPORTANCE Emerging and reemerging coronaviruses cause severe human and animal epidemics worldwide. PEAV is the first bat-like coronavirus to cause infection in domestic animals. However, the PEAV entry mechanism into host cells remains unknown. This study demonstrates that PEAV enters into Vero or IPI-2I cells through caveola/clathrin-mediated endocytosis and macropinocytosis, which does not require a specific receptor. Subsequently, Rab5, Rab7, and Rab9 regulate PEAV trafficking from early endosomes to lysosomes, which is pH dependent. The results advance our understanding of the disease and help to develop potential new drug targets against PEAV.

RESUMO

PURPOSE: Endoplasmic reticulum stress (ERS) plays a crucial role in myocardial ischemia-reperfusion injury (MIRI). Cellular FLICE-inhibitory protein (cFLIP) is an essential regulator of apoptosis and plays a major role in regulating ERS. The present study aimed to investigate the effects of long isoform cFLIP (cFLIPL) on endogenous apoptosis and the mechanism of ERS in MIRI. METHODS: The cFLIPL recombinant adenovirus vector was used to infect H9c2 cells and Sprague-Dawley (SD) rats. After infection for 72 h, ischemia was induced for 30 min, and reperfusion was then performed for 2 h to establish the MIRI model in SD rats. H9c2 cells were hypoxic for 4 h and then reoxygenated for 12 h to simulate ischemia/reperfusion (I/R) injury. Model parameters were evaluated by assessing cardiomyocyte viability, cell death (apoptosis), and ERS-related protein expression. In addition, tunicamycin (TM), an ERS agonist, was also added to the medium for pretreatment. Coimmunoprecipitation (Co-IP) of cFLIPL and p38 MAPK protein was performed. RESULTS: cFLIPL expression was decreased in I/R injury and hypoxia/reoxygenation (H/R) injury, and cFLIPL overexpression reduced myocardial infarction in vivo and increased the viability of H9c2 cells in vitro. I/R and H/R upregulated the protein expression of GRP78, IRE-1, and PERK to induce ERS and apoptosis. Interestingly, overexpression of cFLIPL significantly inhibited ERS and subsequent apoptosis, which was reversed by an agonist of ERS. Moreover, Co-IP showed that cFLIPL attenuated ERS and was associated with inhibiting the activation of p38 protein. CONCLUSION: The expression of cFLIPL is significantly downregulated in MIRI, and it is accompanied by excessive ERS and apoptosis. Upregulated cFLIPL suppresses ERS to reduce myocardial apoptosis, which is associated with inhibiting the activity of p38 MAPK. Therefore, cFLIPL may be a potential intervention target for MIRI.

RESUMO

Objective:To observe the effect of horse-riding squat exercise plus Governor Vessel-regulating Tuina(Chinese therapeutic massage)therapy on static balance function in patients with stroke.Methods:A total of 176 stroke patients were enrolled as the study subjects and divided into four groups by the random number table method,namely horse-riding squat+Tuina group,horse-riding squat group,Tuina group,and control group,with 44 cases in each group.The control group was treated with rehabilitation balance training.The horse-riding squat+Tuina group,horse-riding squat group,and Tuina group were treated with additional horse-riding squat exercise plus Tuina,horse-riding squat exercise,and Tuina treatment,respectively.Four weeks of treatment was regarded as one treatment course.After 1 treatment course,the balance function of the four groups was compared.Results:After treatment,the ellipse area of motion and the length of motion in all four groups were reduced,and the intra-group differences were all statistically significant(P<0.05).The difference in the ellipse area of motion before and after treatment in the horse-riding squat+Tuina group and the horse-riding squat group was larger than that in the control group,and the differences were statistically significant(P<0.05).The difference in the ellipse area of motion before and after treatment in the horse-riding squat+Tuina group was larger than that in the Tuina group,and the difference was statistically significant(P<0.05).The difference in the length of motion before and after treatment in the horse-riding squat+Tuina group,the horse-riding squat group,and the Tuina group was greater than that in the control group,and the differences were statistically significant(P<0.05).There was no statistically significant difference in the pairwise comparison between the horse-riding squat+Tuina group,the horse-riding squat group,and the Tuina group(P>0.05).Conclusion:Horse-riding squat exercise plus Governor Vessel-regulating Tuina therapy can effectively improve the static balance function in patients with stroke.Training the affected lower limb weight-bearing exercise,adjusting the center of gravity distribution,and promoting the mutual balance and coordination between muscle groups may be the mechanism of improving the static balance function.

RESUMO

AIM: To analyze the clinical and histopathological composition of orbital tumors and tumor-like lesions.METHODS: Retrospective case-series study. The clinical histopathological data of 699 cases(707 eyes)with orbital tumor and tumor-like lesions who treated in the orbital disease and ophthalmic plastic department of Tianjin Eye Hospital between January 2010 and December 2020 were collected. All the pathology diagnosis results were divided into three categories which were benign tumor, borderline tumor and malignant tumor according to the eighth edition of the American Joint Committee on Cancer staging system and the 2018 World Health Organization Classification of tumors of the eye. All cases were divided into four groups according to age, including 0~17 years old, 18~39 years old, 40~59 years old, 60 years and above. The histological composition of each group was analyzed.RESULTS: Among the 699 cases(707 eyes), 311 patients(316 eyes)were male and 388 patients(391 eyes)were female. The patient's age at diagnosis ranged from 1 to 84 years(mean 39.9±2.2)years. The right orbit was involved in 307 patients, the left orbit in 384 patients, and 8 patients in bilateral orbit. There were 598 patients(604 eyes, 85.6%)with benign tumor and tumor-like lesions, 7 patients(7 eyes, 1.0%)with borderline tumor, and 94 patients(96 eyes, 13.4%)with malignant tumors. The top 5 benign tumor and tumor-like lesions were cavernous hemangioma(110 cases, 15.7%), dermoid cysts(96 cases, 13.7%), pleomorphic adenomas(54 cases, 7.7%), inflammatory pseudotumors(38 cases, 5.4%), and schwannomas(29 cases, 4.1%)respectively. The top 5 borderline and malignant tumors were non-Hodgkin lymphomas(42 cases, 41.6%), solitary fibrous tumors(12 cases, 11.9%), adenoid cystic carcinomas(11 cases, 10.9%), metastatic tumor(9 cases, 8.9%), and rhabdomyosarcoma(8 cases, 7.9%), respectively. Among the common orbital benign tumors and tumor-like lesions, cavernous hemangioma and pleomorphic adenoma showed a female predominance. Among the common borderline and malignant tumors, non-Hodgkin lymphoma and mesenchymal chondrosarcoma showed a male predominance. The most common benign and malignant tumors were dermoid cysts, rhabdomyosarcomas respectively in group under 18 years old. And dermoid cysts and solitary fibrous tumors were the most common benign and malignant tumors respectively in patients between 18 and 39 years old. Cavernous hemangioma and non-Hodgkin lymphomas were the most common benign and malignant tumors respectively in patients between 40 and 59 years old. While cavernous hemangioma and non-Hodgkin lymphomas were the most common benign and malignant tumors respectively in cases over 60 years old.CONCLUSION: Most orbital tumors and tumor-like lesions are benign. The most common benign orbital tumor is cavernous hemangioma, followed by dermoid cyst. Non-Hodgkin lymphoma is the most common malignant orbital tumor.
