Health-Related Quality of Life in Chinese Patients with Mild and Moderately Active Ulcerative Colitis

Background

Ulcerative colitis (UC) impairs the health-related quality of life (HRQOL). The difference in HRQOL between patients with mild and moderately active UC is not well-defined. Few studies have been conducted to explore the factors that influence HRQOL in Chinese patients. Our study aims were to (1) compare HRQOL of mildly active UC patients with moderate patients; (2) explore the factors that influence HRQOL in Chinese patients with UC; and (3) analyze demographic and disease characteristics of UC in China.

Methods

A total of 110 mild and 114 moderate patients with UC were enrolled. The demographic and disease characteristics were recorded. HRQOL was measured by the Chinese version of the inflammatory bowel disease questionnaire (IBDQ) between mild and moderate patients, male and female patients, and different disease distributions. Stepwise regression analysis was used to assess factors influencing the IBDQ score.

Results

Patients with moderate UC had significantly lower IBDQ total scores compared to patients with mild UC (P=0.001). The IBDQ total score had a negative correlation with the Mayo score (r=–0.263, P<0.001). Stepwise regression analysis showed that the disease activity index and gender had an influence on the IBDQ total score (P<0.05). The female patients had a lower score than the male patients (P<0.05), especially in the emotional function domain (P=0.002). Different disease distributions were not statistically significant in the IBDQ total score (P=0.183).

Conclusions

UC has a negative influence on HRQOL. HRQOL in patients with moderate UC was lower than HRQOL in patients with mild UC, as measured by the IBDQ. UC disease activity has a negative correlation with HRQOL. Gender and the disease activity index are important factors involved in the impairment of HRQOL in Chinese patients with UC. Chinese females may benefit from increased psychological care as part of UC therapy.     

肝癌术后患者心理弹性水平调查及与生存质量、应对方式和创伤后成长的相关性分析

摘要 目的：调查肝癌术后患者心理弹性水平现状,并探讨其与生存质量、应对方式和创伤后成长的相关性。方法：选取2018年11月-2021年3月我院收治的120例原发性肝癌术后住院患者,采用中文版Conner-Davidson心理弹性量表（CD-RICS）对患者心理弹性水平进行调查,另分别采用肝癌患者生活质量测定量表（QOL-LC）、医学应对方式问卷（MCMQ）、创伤后成长评定量表（PTGI）对患者进行问卷调查。采用Spearman法分析原发性肝癌术后患者心理弹性水平与生存质量、应对方式和创伤后成长的相关性。结果：肝癌术后患者心理弹性总分、乐观、自强、坚韧各维度评分均明显低于中国常模得分（P<0.05）;肝癌术后患者各生存质量维度评分均明显低于中国常模得分（P<0.05）;肝癌术后患者面对应对方式得分较中国常模得分低,回避和屈服应对方式得分较中国常模得分高（P<0.05）;肝癌术后患者创伤后成长总分、各维度评分均明显低于中国常模得分（P<0.05）。肝癌术后患者心理弹性总分与各生存质量维度得分呈正相关（P<0.05）。肝癌术后患者心理弹性总分与回避、屈服应对方式呈负相关,与面对应对方式得分呈正相关（P<0.05）。肝癌术后患者心理弹性总分与创伤后成长总分、各维度得分均呈正相关（P<0.05）。结论：肝癌术后患者具有较低的心理弹性水平,心理弹性水平与积极应对方式、生存质量和创伤后成长呈正相关,应采取针对性措施提高肝癌术后患者心理弹性水平,促进患者术后康复。     

The Association Between Effective Dose of Magnesium and Mild Compulsive Exercise on Spatial Learning,Memory, and Motor Activity of Adult Male Rats

The relationship of minerals and trace elements with inflammatory bowel disease (IBD) is complex. Alterations in their metabolism can be induced by the diseases and their complications. To study the role of trace elements in IBD patients’ serum zinc and copper and their related enzymes, including superoxide dismutase (SOD), activity were measured in patients with IBD patients as well as in healthy subjects. In addition, the correlation between serum trace element levels, albumin, total protein, urea level, copper/zinc ratio, and disease activity (DA) was determined in these subjects. Serum samples were obtained from 35 patients (19 ulcerative colitis (UC) and 16 Crohn’s disease (CD)) in the active phase of the disease and 30 healthy control subjects. Serum levels of zinc, copper, SOD activity, albumin, total protein, and urea were measured. The results were compared between the two groups using independent Student’s t test in statistical analysis. Serum levels of zinc, SOD activity, albumin, and total protein were significantly lower (P < 0.05) in patients than controls, while serum urea level was significantly higher in patients compared to controls. Copper concentrations did not differ between patients with IBD (mean ± SD, 58.8 ± 20.7 μg/d) and controls (55.57 ± 12.6 μg/d). Decreased levels of zinc and SOD activity are associated with increased inflammatory processes indicating inappropriate antioxidant system in patients with IBD. Additionally, lower levels of albumin and total protein with higher level of urea reflect metabolic problems in liver system.     

Dynamic thiol/disulphide homeostasis before and after radical prostatectomy in patients with prostate cancer

Abstract

Thiol groups are important anti-oxidants and essential molecules protecting organism against the harmful effects of reactive oxygen species (ROS). The aim of our study is to evaluate thiol–disulphide homeostasis with a novel recent automated method in patients with localized prostate cancer (PC) before and six months after radical prostatectomy (RP). 18 patients with PC and 17 healthy control subjects were enrolled into the study. Blood samples were collected from the controls subjects and patients before and six months after RP. Thiol–disulphide homeostasis was determined using a recently developed novel method. Prostate-specific antigen (PSA), albumin, total protein, total thiol, native thiol, disulphide and total antioxidant status (TAS) were measured and compared between the groups. Native thiol, total thiol and TAS levels were significantly higher in the control group than the patients before RP (p?<?.001). There was a non-significant increase in the native thiol, total thiol and TAS levels in the patients six months after RP in comparison to the levels before RP (p values .3, .3 and .09, respectively). We found a significant negative correlation between PSA and thiol levels. Our study demonstrated that the decreased thiol and TAS levels weakened anti-oxidant defence mechanism in the patients with PC as indicated. Increased oxidative stress in prostate cancer patients may cause metabolic disturbance and have a role in the aetiopathogenesis of prostate cancer.     

耐多药肺结核患者心理健康状况调查及与应对方式、社会支持的相关性研究

摘要 目的：探讨耐多药肺结核患者心理健康状况的影响因素,分析其及与应对方式、社会支持的相关性。方法：选择2018年4月至2020年5月我院诊治的101例耐多药肺结核患者作为观察组,选择同期99例敏感肺结核患者作为对照组。两组均测评症状自评量表-90(SCL-90)评分、医学应对问卷(MCMQ)评分以及社会支持评定量表(SSRS)评分,分析SCL-90总评分与MCMQ各因子评分、SSRS总评分的相关性,采用Logistic回归模型分析心理健康状况的影响因素。结果：与对照组相比,观察组的躯体化、人际关系、抑郁、焦虑、敌对性、恐怖和精神病性评分以及总评分明显提高（P<0.05）。与对照组相比,观察组的面对评分、客观支持、主观支持、支持利用度评分以及总评分均降低（P<0.05）。Pearson相关性分析显示,SCL-90总评分与MCMQ评分中的回避和屈服评分呈正相关性（r=0.386、0.311,均P<0.05）,SCL-90总评分与SSRS总评分呈负相关（r=-0.332,P<0.05）。多因素Logistic回归分析显示,经济状况差、躯体健康状况差、病情严重、睡眠质量差和生活满意度低是耐多药肺结核患者心理健康不良的独立危险因素（P<0.05）。结论：耐多药肺结核患者心理健康状况差,应对方式选择面对较少,总体社会支持水平较低,患者的心理健康状况与应对方式、社会支持存在一定的相关性。在提供躯体性治疗的基础上,应结合患者的心理健康状况及相关危险因素给予适当干预。     

T-cell subsets in peripheral blood of patients with newly diagnosed and posttreatment Hodgkin's and non-Hodgkin's lymphomas. Analysis by monoclonal antibody staining and flow cytometry

T-cell subsets in the peripheral blood of patients with Hodgkin's disease (HD) and non-Hodgkin's lymphomas (NHLs) were determined using anti T-cell monoclonal antibodies and flow cytometry. Forty HD patients and 30 NHL patients were evaluated; 76 normal blood donors served as controls. Newly diagnosed (untreated) HD and NHL patients had relatively normal values for percentages of total T-cells, helper cells and suppressor cells; their helper/suppressor ratios were also normal. The total lymphocyte count was normal for pretreatment HD, but lower than normal for NHL. Following treatment, both HD and NHL patients showed significantly decreased helper/suppressor ratios, caused by a significant decrease in the percentage of helper cells in HD patients and a significant increase in the percentage of suppressor cells in the small number of NHL patients studied. A small number of NHL patients, followed without specific treatment (passive follow-up), had relatively normal values for percentages of helper and suppressor cells and total T-cells. For both groups of patients off treatment, it is concluded that the lower helper/suppressor ratios are due to the prolonged effects of treatment (predominantly irradiation).

目的:探讨D-二聚体和纤维蛋白原水平预测支气管动脉栓塞术治疗支气管扩张大咯血的临床疗效及预后的临床价值。方法:选取50例2011年11月至2016年11月期间于我院治疗的支气管扩张大咯血患者进行研究,所有患者均进行支气管动脉栓塞术治疗,根据临床疗效评价标准结果分为总有效组(n=40)和无效组(n=10),随访1年,根据预后的复发情况分为预后好组(n=38)和预后差组(n=12),分别比较总有效组和无效组、预后好组和预后差组D-二聚体和纤维蛋白原水平,采用受试者工作特征(ROC)曲线分析D-二聚体和纤维蛋白原对支气管扩张大咯血患者的预测价值。结果:手术后总有效组和无效组患者D-二聚体、纤维蛋白原水平均高于手术前,且总有效组高于无效组(P0.05)。手术后预后好组和预后差组患者D-二聚体、纤维蛋白原水平均高于手术前,且预后好组高于预后差组(P0.05)。ROC曲线分析显示,D-二聚体和纤维蛋白原对支气管扩张大咯血患者均具有较高的敏感度和特异度,曲线下面积分别为0.725和0.806。结论:采用支气管动脉栓塞术治疗支气管扩张大咯血,疗效及预后比较好的患者D-二聚体和纤维蛋白原水平均较高,并且其敏感度和特异度较高,具有一定的临床预测价值。     

Total and high molecular weight adiponectin and hepatocellular carcinoma with HCV infection

Background

Adiponectin is shown to be inversely associated with development and progression of various cancers. We evaluated whether adiponectin level was associated with the prevalence and histological grade of hepatocellular carcinoma (HCC), and liver fibrosis in patients with hepatitis C virus (HCV) infection.

Methods

A case-control study was conducted on 97 HCC patients (cases) and 97 patients (controls) matched for sex, Child-Pugh grade and platelet count in patients with HCV infection. The serum total and high molecular weight (HMW) adiponectin levels were measured by enzyme-linked immunosorbent assays and examined in their association with the prevalence of HCC. In addition, the relationship between these adiponectin levels and body mass index (BMI), progression of liver fibrosis, and histological grade of HCC was also evaluated. Liver fibrosis was assessed using the aspartate aminotransferase to platelet ratio index (APRI).

Results

There were no significant differences in the serum total and HMW adiponectin levels between cases and controls. Moreover, there were no inverse associations between serum total and HMW adiponectin levels and BMI in both cases and controls. On the other hand, serum total and HMW adiponectin levels are positively correlated with APRI in both cases (r = 0.491, P<0.001 and r = 0.485, P<0.001, respectively) and controls (r = 0.482, P<0.001 and r = 0.476, P<0.001, respectively). Interestingly, lower serum total (OR 11.76, 95% CI: 2.97–46.66 [P<0.001]) and HMW (OR 10.24, CI: 2.80–37.40 [P<0.001] adiponectin levels were independent risk factors of worse histological grade of HCC.

Conclusions

Our results suggested that serum total and HMW adiponectin levels were predictors of liver fibrosis, but not prevalence of HCC in patients with HCV infection. Moreover, low these adiponectin levels were significantly associated with worse histological grades.     

Cancer chemotherapy reduces plasma total polyphenols and total antioxidants capacity in colorectal cancer patients

Our aim was to investigate the effect of chemotherapy on plasma total antioxidant capacity and polyphenols in patients with colon cancer. Plasma samples were collected from 70 CRC patients under chemotherapy treatment, and 15 non-treated patients. The control group included 71 healthy individuals. Plasma ABTS and FRAP were measured as biomarkers of antioxidant total capacity and the total phenols as an indicator to determine the polyphenols levels in plasma. Treatment with chemotherapy protocols resulted in a significant decrease of ABTS (-24?%, p?相似文献   

MFN2 gene analysis in patients with hereditary motor and sensory neuropathy from Bashkortostan Republic

Hereditary motor and sensory neuropathy (HMSN) type IIA is caused by mutations in the mitofusin type-2 (MFN2) gene and represents one of the most common axonal forms of HMSN. We determined the spectrum and frequency of MFN2 gene mutations in patients from the Bashkortostan Republic (BR). Four different mutations were revealed in 5 out of 170 unrelated patients, i.e., c.2113G>A (p.Val705Ile) (1.2% among all types of HMSN in the total sample of patients and 2% among patients of Tatar ethnicity). This mutation was described previously; c.775C>T (p.Arg259Cys) (0.6%, in the total sample of patients and 2% among the patients of Tatar ethnicity); c.776G>A (p.Arg259His) (0.6% in the total sample of patients and 1.5% among the patients of Russians ethnicity); and c.2171T>C (p.Leu724Pro) (1.2% in the total sample of patients and 7.4% among the patients of Bashkirs ethnicity). These are new mutations that were not observed among healthy family members and in control samples of healthy subjects. Five identified nucleotide substitutions represent single nucleotide polymorphisms of the gene, including c.892G>A (p.Gly298Arg), c.957C>T (Gly319Gly), and c1039-222t>c, which were described previously, while c.175+28c>t and c.2204+15t>c represent new nucleotide substitutions in the intron regions of the gene.     

Lipid peroxidation and antioxidant status in blood and tissue of malignant breast tumor and benign breast disease

Changes in the levels of malondialdehyde (MDA), nitrate and nitrite (as an index of nitric oxide production), lipid hydroperoxide (LOH), total antioxidant capacity (TAC), lipids (total cholesterol and triglycerides) and lipoproteins (HDL- and LDL-cholesterol) were estimated in breast cancer patients (n = 15) and benign breast disease (n = 15). Serum and tissue MDA levels were found to be decreased in breast cancer patients compared to the benign group (p < 0.05). In contrast, nitrate and nitrite levels were increased in serum and tissue of the cancer group compared to benign breast disease patients (p < 0.05). Compared to the benign group, tissue TAC levels were elevated in the breast cancer patient group (p < 0.05). Total cholesterol and HDL-cholesterol were elevated in the benign group compared with cancer patients (p < 0.05). These findings support the hypothesis that lipid peroxidation in serum and tissue of benign breast disease is greater than in breast cancer. However, the enhanced levels of nitric oxide may be in response to inflammation in patients with breast cancer. Total antioxidant status is lower in benign tissue than in cancerous tissue, probably to compensate for this elevated free radical production.     

The Prevalence of Euthyroid Hypertriiodothyroninemia in Newly Diagnosed Multiple Myeloma and its Clinical Characteristics

ObjectiveTo evaluate the prevalence of euthyroid hypertriiodothyroninemia and/or hyperthyroxinemia and its clinical characteristics in multiple myeloma (MM) patients.MethodsPreviously untreated, newly diagnosed patients with MM were enrolled at the Beijing Chao-yang Hospital between January 2016 and December 2019. Thyroid function and clinical characteristics were analyzed.ResultsA total of 105 patients were enrolled in this study. Thirteen (12.38%) patients exhibited euthyroid hypertriiodothyroninemia with strikingly elevated total triiodothyronine (TT3) levels (>8 ng/mL). Among these 13 patients, 12 patients were immunoglobulin (Ig) G type (92.31%), and 1 patient was light-chain κ type (7.69%). Compared with other patients with MM, patients with hypertriiodothyroninemia were more likely to be IgG type and had higher serum globulin and lower albumin levels and more advanced International Staging System stage (all P < .05). Among the 13 euthyroid hypertriiodothyroninemia patients, 8 patients have been followed up and checked for thyroid function. The TT3 levels in all 8 patients were normalized to the reference range after antimyeloma chemotherapy.ConclusionAbout 12% of patients with MM had euthyroid hypertriiodothyroninemia. Their strikingly elevated TT3 was normalized after chemotherapy. Clinicians should be aware of the possibility of high TT3 levels in euthyroid patients with MM and the potential risk of MM in patients with strikingly elevated TT3.     

Improved durable pulmonary vein isolation with shorter procedure times and lower energy levels using RF ablation with ablation index and a stringent lesion contiguity

BackgroundThe single procedure success rates of durable pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (PAF) varies between 80 and 90%. Ablation index, incorporating contact force, stability, time and power is a more profound parameter of significant lesion size and has been established. Equally important is a stringent contiguity of the lesion set.Methods and resultsA total number of 100 consecutive patients undergoing de-novo catheter ablation for paroxysmal atrial fibrillation (PAF) were analyzed between 2016 and 2019. In the first 50 patients (group A) PVI was performed using a surround flow, contact force catheter (Biosense Webster Thermocool STSF, Biosense Webster, USA) with a drag-and-ablate technique to encircle the PVs. In the following 50 patients (group B), PVI was performed using ablation index and a stringent lesion contiguity with an interlesion distance (ILD) of <5 mm. The baseline characteristics showed no significant differences between both groups. During a mean follow-up of 18 ± 3 months after a single procedure, 36 (72%) patients of group A were free of arrhythmia recurrence versus 43 (86%) patients in group B (p = 0.047). A total of 14 patients (group A: 10 (20%), group B: 4 (8%); underwent a redo-procedure. 7 patients of group A (14%) and 2 patients of group B (4%) showed recovered veins. In 3 patients of group A and 2 patients of group B the PVs were durably isolated. In these patients persistent AF recurrence was caused by extra-PV AF sources. Four patients of group A and three patients of group B had continued paroxysmal or persistent AF but did not undergo redo-procedure. With regard to the procedural data, the procedure time, the total energy and the fluoroscopy time were significantly lower in group B (AI and ILD <5 mm) (128.86 ± 18.19 versus 115.35 ± 15.38; p < 0.05; 1619.16 ± 988.56 versus 1186.26 ± 756.34; p < 0.05; 11.49 ± 3.20 versus 9.66 ± 3.86; p = 0.04). Both procedures were performed with a low number of complications, no pericardial effusion was seen in either group.ConclusionsPVI using ablation index in combination with a stringent lesion contiguity improves clinical outcome after first-time PVI with lower PVI recovery, shorter procedure times, lower total energy and shorter fluoroscopy times and therefore, is more efficient.     

Oxidative stress and ischemia-modified albumin in chronic ischemic heart failure

Abstract

Objectives

Knowledge about the role of oxidative stress in human diseases, including cardiovascular system disorders, emphasizes the need for reliable markers of oxidative stress. Here, we evaluated the levels of the novel marker ischemia-modified albumin (IMA), albumin-adjusted IMA (adj-IMA), and the IMA/serum albumin ratio (IMAR) in patients with chronic ischemic heart failure (CIHF).

Methods

A total of 55 patients with CIHF and 40 age- and sex-matched healthy individuals were included in the study. Serum levels of IMA, total antioxidant status, and total oxidant status were analyzed, and the adj-IMA level, IMAR, and oxidative stress index were calculated.

Results

Serum IMA, IMAR, total oxidant status levels, and oxidative stress index were significantly higher in patients with CIHF than in the controls (all P < 0.0001), whereas albumin and total antioxidant status levels were significantly lower in the CIHF patients (P < 0.0001 and P = 0.0004, respectively). However, there was no significant difference in serum adj-IMA levels between the groups (P = 0.8).

Discussion

We observed impaired oxidant/antioxidant status in favor of oxidative stress in CIHF patients. Oxidative stress may be a key factor in the development of hypoalbuminemia in CIHF. Further studies are needed to establish the relationships among IMA, albumin, and redox balance in CIHF.     

Vitamin d status and its relationship with bone mineral density and parathyroid hormone in southeast asian adults with low bone density

ObjectiveTo investigate the vitamin D sufficiency status and the relationships among serum 25-hydroxyvitamin D [25(OH)D] levels, intact parathyroid hormone (iPTH) levels, and bone mineral density (BMD) in patients attending an osteoporosis clinic in Singapore.MethodsIn total, 193 adults with or without prevalent fragility fractures and with low BMD at the femoral neck, total hip, or lumbar spine underwent assessment. Multivariate regression models were used to investigate the relationships among serum 25(OH)D, iPTH, and BMD.ResultsThe mean values (standard deviation) for age of the patients and serum 25(OH)D level were 61 (14) years and 26.05 (7.97) ng/mL, respectively. In 72% of patients, serum 25(OH)D levels were below 30 ng/mL. There was no association between 25(OH)D levels and BMD at the femoral neck, total hip, or lumbar spine(P = .568, .461, and .312, respectively). Serum iPTH levels were negatively associated with BMD at the total hip(P = .035) and the lumbar spine (P = .019). At levels < 30 ng/mL, 25(OH)D was negatively associated with iPTH (P = .036).ConclusionAmong this Southeast Asian population of patients with low BMD, no direct relationship between serum 25(OH)D levels and BMD was observed. A negative correlation existed, however, between iPTH and 25(OH)D at serum 25(OH)D concentrations < 30 ng/mL, and serum iPTH levels showed a significant negative association with BMD at the total hip and lumbar spine. These significant negative associations between iPTH levels and BMD at the total hip and lumbar spine underscore the critical role of this hormone in bone metabolism and health.

Body Fat Patterning,Hepatic Fat and Pancreatic Volume of Non-Obese Asian Indians with Type 2 Diabetes in North India: A Case-Control Study

ObjectiveTo evaluate body fat patterning and phenotype including hepatic fat and pancreatic volume of non-obese (BMI: < 25 kg/m²) Asian Indians with type 2 diabetes residing in North India.MethodsNon-obese patients with type 2 diabetes (n = 93) and non-obese, normo-glycemic subjects (n = 40) were recruited. BMI, waist & hip circumferences, skinfold thickness at 8 sites, body fat, lean mass and detailed abdominal fat evaluation [total abdominal fat, total subcutaneous fat (superficial, deep, anterior, and posterior), total intra-abdominal fat (intra-peritoneal, retroperitoneal)], liver span, grades of fatty liver and pancreatic volume were compared.ResultsWaist circumference, subscapular skinfolds and total truncal fat (on DEXA) were higher whereas calf, total peripheral skinfolds and total leg fat (on DEXA) lower in patients. Specifically, the following volumes were higher in cases as compared to controls; total abdominal fat (19.4%), total intra-abdominal fat (49.7%), intra-peritoneal fat (47.7%), retroperitoneal fat (70.7%), pancreatic volume (26.6%), pancreatic volume index (21.3%) and liver span (10.8%). In cases, significant positive correlations were observed for pancreatic volume with BMI, waist and hip circumferences, W-HR, subscapular, abdominal and total truncal skinfolds, truncal, total subcutaneous, total intra-abdominal, intra-peritoneal, retroperitoneal fat depots, liver span and fatty liver.ConclusionsIn non-obese Asian Indians with type 2 diabetes, subcutaneous and intra-abdominal obesity, including fatty liver, and pancreatic volume were higher and peripheral subcutaneous adiposity was lower than BMI matched non-diabetic subjects.

口腔颌面部肿瘤患者术后缺损的外侧皮瓣修复术与前臂皮瓣修复术对比研究

摘要 目的：探讨口腔颌面部肿瘤患者术后缺损的外侧皮瓣修复术与前臂皮瓣修复术对比。方法：选取遂宁市中心医院（我院）2015年8月到2020年8月共收治的120例口腔颌面部肿瘤患者,所有患者通过肿瘤切除术后均出现组织缺损现象,对所有组织缺损的患者依照不同的皮瓣修复方式分为两组,其中应用外侧皮瓣修复术的68例患者分为外侧皮瓣修复组,应用前臂皮瓣修复术的52例患者分为前臂皮瓣修复组,对比两组的皮瓣修复效果,治疗后的口腔功能恢复情况,瓣成活率、术后皮瓣危象率以及血管吻合时间,并发症情况。结果：外侧皮瓣修复组的总有效率为95.59 %,前臂皮瓣修复组的总有效率为84.62 %,外侧皮瓣修复组明显高于前臂皮瓣修复组（P＜0.05）;外侧皮瓣修复组患者的外形修复、语言功能、咀嚼功能、吞咽功能以及口腔闭合评分明显高于前臂皮瓣修复组（P＜0.05）;两组的皮瓣成功率均比较高对比无明显差异（P＞0.05）,两组的术后皮瓣危象率比较低,对比无明显差异（P＞0.05）,血管吻合时间对比无明显差异（P＞0.05）;对比两组并发症发生情况发现,外侧皮瓣修复组的总并发症发生率为2.94 %,前臂皮瓣修复组并发症发生率为17.31 %,外侧皮瓣修复组明显低于前臂皮瓣修复组（P＜0.05）。结论：对口腔颌面部肿瘤患者术后缺损患者应用外侧皮瓣修复术能够提升患者的皮瓣修复效果,提升患者的口腔功能恢复情况,减少并发症的发生,安全性好,值得临床应用推广。
