  • 自然愈合与玻璃体切割手术治疗的外伤性黄斑裂孔患者临床特征及治疗方式选择研究现状

    外伤性黄斑裂孔是指眼球在受到直接或者间接、闭合或者开放的外力创伤下立即或者延迟发生的黄斑部位裂孔。治疗主要有玻璃体切割手术和非手术观察治疗两种方式。根据其临床特征不同, 选择玻璃体切割手术或非手术观察治疗的主要考虑因素为患者年龄、黄斑裂孔大小、合并眼底损伤情况、患者身体基础疾病等。裂孔直径为0.2个视盘直径(DD)左右的患者, 裂孔自行闭合可能性大。观察1~6个月裂孔扩大、视力下降应及时终止观察改行手术治疗。裂孔直径在0.3 DD左右, 未合并眼底出血、视网膜脱离的年轻患者, 可优先考虑手术治疗, 争取获得较好的视力恢复。裂孔直径>0.3 DD或者裂孔<0.3 DD但合并眼底其他损伤的患者, 也可优先考虑手术治疗, 以其获得良好的裂孔闭合。

  • Clinical efficacy of vitrectomy combined with modified inverted internal limiting membrane flap covering technique for complicated macular hole

    ObjectiveTo observe the clinical efficacy of vitrectomy combined with modified inverted internal limiting membrane (ILM) flap covering technique for complicated macular hole (MH).MethodsThis is a retrospective case series. Twenty-one eyes of 20 patients who underwent vitrectomy combined with modified inverted ILM flap covering technique were enrolled in this study. Among these eyes, 9 eyes were idiopathic MH (IMH), with the mean basal diameter of (1 188.3±155.1) μm, minimum diameter of (626.9±86.2) μm, logarithm of the minimum angle of resolution (logMAR) best corrected visual acuity (BCVA) of 1.1±0.3; 2 eyes were MH with high myopia, with the mean basal diameter of (696.5±232.6) μm, minimum diameter of (259.0±69.3) μm, logMAR BCVA of 1.3; 5 eyes were high myopia MH with retinal detachment (RD), with the mean BCVA of 1.5±0.1; 3 eyes were rhegmatogenous RD (RRD) with MH, with the mean logMAR BCVA of 1.6; 2 eyes were MH after vitrectomy for RRD, with the mean basal diameter of (1 606.0±69.3) μm, minimum diameter of (909.0±387.5) μm, logMAR BCVA of 1.6. All patients received 23G or 25G vitrectomy after removal of posterior vitreous cortex intraoperatively. Indocyanine green staining assisted circle-wise ILM peeling was performed. ILM of diameter 1.5 disc-diameters around fovea was residual and loosened; perfluoronoctane assisted inverting superior or temporal residual ILM covering on macular hole. C3F8, gas or silicone oil tamponade was performed at the end. BCVA and hole closure were followed up for 1-4 months. C3F8, gas or silicone oil was tamponaded at the end. BCVA and hole closure were followed up for 1-4 months.ResultsMH of 21 eyes were closed after surgery. Nine IMH were closed at typeⅠ, with U shape closure in 7 eyes, V shape closure in 2 eyes. Two eyes of MH with high myopia, 3 eyes of RRD with MH, 2 eyes of MH after vitrectomy for RRD were closed at typeⅠ of U shape. Five eyes of high myopia MHRD including MH closure at typeⅠof U shape 3 eyes, typeⅡ of W shape 2 eyes. The mean logMAR BCVA of IMH, MH with high myopia, high myopia MHRD, RRD with MH, MH after vitrectomy for RRD eyes were 0.8±0.3, 0.9±0.2, 1.4±0.1, 0.7±0.3, 0.9±0.2, respectively. The mean postoperative logMAR BCVA in IMH eyes was improved compared preoperative one (P=0.02). There was no obvious change of pre-and postoperative logMAR BCVA in MH with high myopia, high myopia MHRD, RRD with MH, MH after vitrectomy for RRD eyes (P=0.18, 0.10, 0.11, 0.18).ConclusionVitrectomy combined with inverted ILM flap covering technique for complicated MH is an effective method to improve the success rate of MH closure and the visual function.

  • The choroidal thickness and blood flow in the subfoveal area with idiopathic macular hole by spectral-domain optical coherence tomography

    ObjectiveTo observe the subfoveal choroidal thickness (SFCT) and choriocapillary blood flow area (CBFA) in the patients with idiopathic macular hole (IMH).MethodsThis is a prospective clinical study. Thirty-two patients with unilateral IMH (4 in stage 2, 17 in stage 3, 11 in stage 4) and 32 age- and sex-matched normal controls were enrolled in this study. All eyes were divided into three groups, including group A (32 affected eyes), group B (32 fellow eyes) and group C (32 normal eyes of controls). There was no significant difference in age (t=0.865) and gender (χ2=0.000) in IMH patients versus normal control subjects (P>0.05). There was no significant difference in refraction (F=0.957) and ocular axial length (F=0.562) between group A, B and C. The SFCT was detected by enhanced depth imaging of spectral-domain optical coherence tomography (OCT). The CBFA was detected by OCT angiography. The differences of SFCT and CBFA in three groups were analyzed by Kruskal-Wallis and non-parametric test.ResultsThe mean SFCT was (182.53±64.52) μm in group A, (199.21±73.07) μm in group B and (254.21±56.85) μm in group C respectively. The SFCT was thinner in group A and B than that in group C (Z=−4.362, −3.190; P<0.05), but was the same in group A and B (Z=−1.171, P>0.05). The mean CBFA was (5.09±0.31) mm2 in group A, (5.41±0.20) mm2 in group B and (5.39±0.15) mm2 in group C respectively. The CBFA was reduced in group A than that in group B and C (Z=−4.467, −4.048; P<0.05), but was same in group B and C (Z=0.420, P>0.05).ConclusionSFCT and CBFA are both reduced in IMH eyes.

  • High-intensity intermittent aerobic exercise on exercise capacity and quality of life in patients with heart failure: a meta-analysis

    ObjectivesTo systematically review the efficacy of high-intensity intermittent exercise (HIIE) on cardiac function, exercise capacity, quality of life and depression in patients with heart failure.MethodsPubMed, Web of Science, The Cochrane Library, EBSCOhost, EMbase, CBM, CNKI, WanFang Data and VIP databases were electronically searched to collect randomized controlled trials (RCTs) on HIIE on cardiac function, exercise capacity, quality of life and depression in patients with heart failure from inception to April, 2019. Two reviewers independently screened literature, extracted data, and assessed risk of bias of included studies. Then, RevMan 5.3 software and Stata 15.1 software were used for meta-analysis.ResultsA total of 16 RCTs involving 549 patients were included. The results of meta-analysis showed that, compared with the control group, HIIE could increase peak oxygen consumption (MD=2.04, 95%CI 0.74 to 3.33, P=0.002), peak work rate (MD=12.85, 95%CI 1.17 to 24.52, P=0.03), left ventricular ejection fraction (MD=4.24, 95% CI 1.40 to 7.07, P=0.003), quality of life (MD=7.32, 95%CI 1.41 to 13.22, P=0.02), and the six minute walk distance (MD=42.46, 95%CI 20.40 to 64.52, P=0.000 2). However, there was no significant difference between two groups in the depression score (SMD=0.39, 95%CI −0.52 to 1.31, P=0.40) and VE/VCO2 Slope (MD=0.12, 95%CI −1.02 to 1.26, P=0.84).ConclusionsCurrent evidence shows that compared with routine exercise or moderate intensity exercise, HIIE can improve exercise capacity, quality of life and cardiac function in patients with heart failure, but there is no significant difference in improving depression. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusion.

  • The Effectiveness of Comfeel Hydrocolloid Dressings in Preventing Peripheral Phlebitis Caused by Intravenous Infusions

    ObjectiveTo investigate the effectiveness of hydrocolloid dressing in preventing peripheral phlebitis due to intravenous infusions. MethodsFrom April 1st to October 30th, 2014, 320 patients admitted in the Biliary Department of West China Hospital for parenteral nutrition were collected along with their clinical data and were randomly divided into control group and intervention group. A total of 160 patients who were allocated in the control group accepted simple dressing with 3M adhesive tape (6 cm×7 cm) at the intravenous catheter site. In contrast, hydrocolloid dressing (5 cm×7 cm) was applied at the intravenous catheter site and then covered with 3M adhesive tape (6 cm×7 cm) for the patients in the intervention group. ResultsPhlebitis rate was significantly higher in the control group (115 patients) than that in the interventions group (64 patients) (χ2=32.978, P<0.001). In addition, the severity of phlebitis was higher in the control group than that in the intervention group (Z=-4.466, P<0.001). Statistically significant difference was noted. ConclusionHydrocolloid dressing is effective in preventing and delaying the occurrence of peripheral phlebitis due to intravenous infusions.

  • Exploring predictive factors for extubation in mechanically ventilated patients with moderate to severe traumatic brain injury

    ObjectiveTo explore the predictive factors for extubation in mechanically ventilated patients with moderate to severe traumatic brain injury (TBI). MethodsMechanically ventilated adult patients with moderate to severe brain injuries admitted to the People’s Hospital of Hunan province were selected between April 2020 and March 2022. The general data, neurological function and airway protective ability of the patients were collected. The patients were divided into successful extubation and failed extubation groups based on extubation outcomes. The differences in various indicators between the two groups were compared. Univariate and multivariate logistic regression analyses were conducted to determine the influencing factors for tracheal tube extubation in patients with moderate to severe TBI. Receiver operating characteristic (ROC) curves were plotted to analyze the predictive value of each indicator for extubation in TBI patients. ResultsA total of 263 patients with moderate to severe TBI were included in the analysis, with 183 patients in the successful extubation group and 80 patients in the failed extubation group. The successful extubation group had higher Glasgow coma scale (GCS) and cough peak flow (CPF) compared to the failed extubation group. The incidence of ventilator-associated pneumonia (VAP), duration of mechanical ventilation, length of ICU stay, and length of hospital stay were all lower in the successful extubation group. Univariate and multivariate logistic regression analyses showed that the predictive factors for tracheal tube extubation in patients with moderate to severe TBI were CPF and GCS at the time of extubation. Adjusting for confounding factors, every 1 L/min increase in CPF at the time of extubation reduced the risk of extubation failure by 2% [odds ratio (OR) = 0.98, 95% confidence interval (CI) 0.97 - 0.99], and every 1-point increase in GCS reduced the risk of extubation failure by 12% (OR = 0.88, 95%CI 0.79 - 0.98). ROC curve analysis showed that CPF, GCS, GCS eye, and GCS motor had predictive value for tracheal tube extubation in patients with moderate to severe TBI. When patients simultaneously met the criteria of GCS≥8 (GCS motor≥5, GCS eye≥3) and CPF ≥68.5 L/min, the diagnostic value for predicting successful extubation was highest, with an area under the ROC curve of 0.946 (95%CI 0.917 - 0.975), sensitivity of 0.850, and specificity of 0.907. ConclusionCPF ≥ 68.5 L/min and GCS ≥ 8 have clinical guiding value for successful extubation in mechanically ventilated patients with moderate to severe traumatic brain injury.
