Objective:
To observe the changes of retinal microstructure in lamellar macular hole (LMH) after vitrectomy.
Methods:
A retrospective clinical observational study. Forty patients (41 eyes) with LMH and received vitrectomy in Ophthalmology Department of Peking University People’s Hospital from January 2014 to September 2018 were included in this study. Among them, 14 patients (15 eyes) were males and 26 patients (26 eyes) were females, with an average age of 67.8±8.6 years. There were 37 eyes with a lens and 4 eyes with an IOL. There were 29 eyes with LMH of tractional type, 7 eyes of degenerative type, and 5 eyes of mixed type. All patients underwent BCVA and OCT examinations. The BCVA examination was performed using the international standard visual acuity chart, which was converted into logMAR visual acuity. The average logMAR BCVA was 0.57±0.27; the mean macular retinal thickness (CRT) was 192.3±108.9 μm, the mean macular thickness (MRT) was 427.5±110.2 μm. Among the 29 eyes of tractional type, there were 17 eyes with retinal cavity, 8 eyes with macular retinoschisis, and 3 eyes with incomplete ellipsoid zone. Among the 7 eyes of degenerative type, there were 5 eyes with lamellar hole-associated epiretinal proliferation (LHEP), 5 eyes with retinal cavity, and 5 eyes with incomplete ellipsoid zone. Among the 5 eyes of mixed type, 2 eyes with LHEP, 1 eye with macular epiretinal membrane, and 4 eyes with incomplete ellipsoid zone. The average follow-up time after surgery was 12.8±5.2 months. Among them, 10 eyes were followed up for equal or greater than 24 months. After the surgery, the same equipment and method before the surgery were used for relevant examination. The changes of BCVA, CRT, and MRT before and after surgery were observed. Continuous variables were compared by

Objective:To investigate the associations between small diffusion-weighted imaging (DWI) hyperintensities lesions and total cerebral small vessel disease (cSVD) burden and the influence on prognosis in patients with acute intracerebral hemorrhage (ICH).Methods:Consecutive patients with acute spontaneous ICH from January 2018 to June 2021 were recruited in the Stroke Center of Zhengzhou People′s Hospital. Magnetic resonance imaging was performed to quantify DWI hyperintensities lesions and cSVD imaging markers, including white matter hyperintensities, enlarged perivascular spaces, lacunes and cerebral microbleeds, which were calculated for the total cSVD burden (0-4 points). The prognosis was assessed with the modified Rankin Scale (mRS) at discharge and 90-day. Multivariable Logistic regression models were adopted to explore the associations between DWI lesions and total cSVD burden and clinical outcome.Results:Of 283 included patients, 59 (20.8%) had small DWI lesions, 32 (11.3%) had multiple lesions. They were mostly punctate, mainly located in the cortical and subcortical regions, and scattered in multiple vascular territories. With the increase of cSVD burden, the number of DWI lesions gradually increased. Spearman correlation analysis showed that the total cSVD burden was positively correlated with the number of DWI lesions ( r=0.21, P<0.001). In multivariable regression analyses, the total cSVD burden was independently associated with DWI lesions ( OR=1.63, 95% CI 1.23-2.15, P=0.001). The 90-day poor outcome (mRS scores≥4) in patients with DWI lesions was significantly higher than those without DWI lesions (39.3% vs 16.3%, χ 2=14.38, P<0.001), while there was no statistically significant difference in the poor outcome of discharge between the two groups (26.5% vs 17.7%, χ 2=3.06, P=0.080). With the increase in the number of DWI lesions, the 90-day poor outcome increased significantly (trend chi-squared test χ 2=11.50, P=0.001). Multivariable analyses showed that DWI lesions ( OR=4.39, 95% CI 1.92-10.03, P<0.001) and their number ( OR=1.42, 95% CI 1.06-1.90, P=0.018) were independently associated with the 90-day poor outcome. Conclusions:Higher total cSVD burden is an independent risk factor for small DWI lesions in patients with ICH. Small DWI lesions were independently associated with the 90-day poor outcome, but not with the discharge outcome.

Objective:To investigate the value of a nomogram predicting the outcome of intracerebral hemorrhage (ICH) based on clinical characteristics and diffusion-weighted imaging (DWI) of hyperintense lesions.Methods:A case-control study. Consecutive patients, aged 30-88(59±13) years old, with ICH were recruited at the Stroke Center of Zhengzhou People′s Hospital from January 2018 to August 2021. Patients were divided into a group with DWI lesions and a group without DWI lesions depending on whether there were DWI hyperintense lesions distant from the hematoma. Prognosis was evaluated at 90 days via the modified Rankin Scale (mRS). Univariate and multivariable logistic regression models were used to identify independent predictors of a poor ICH outcome (mRS score≥4), and a nomogram model was developed. The performance of the nomogram was validated via the area under the receiver operating characteristic curve (AUC) and a calibration chart.Results:Of the 303 patients included in the study, 24.8% presented with DWI lesions; 17.5% with asymptomatic DWI lesions and 7.3% with symptomatic DWI lesions. Poor outcomes were significantly more frequent in the group with DWI lesions than in the group without DWI lesions ( χ2=21.32, P<0.001). In multivariable regression analysis, age [odds ratio ( OR)=1.032, 95% confidence interval ( CI) 1.002-1.063, P=0.035], hematoma volume ( OR=1.050, 95% CI 1.011-1.090, P=0.012), hematoma location ( OR=3.839, 95% CI 1.248-11.805, P=0.019), DWI lesions ( OR=3.955, 95% CI 1.906-8.206, P<0.001), and baseline NIHSS scores ( OR=1.102, 95% CI 1.038-1.170, P=0.001) were independent predictors of a poor outcome. In subgroup analysis patients with asymptomatic DWI lesions had a 3-fold greater risk of a poor outcome compared to those without DWI lesions ( OR=3.135, 95% CI 1.382-7.112, P=0.006), and patients with symptomatic DWI lesions had a 7-fold greater risk of a poor outcome compared to those without DWI lesions ( OR=7.126, 95% CI 2.279-22.277, P=0.001). A nomogram model was established based on the independent predictors for a poor outcome. The AUC of the nomogram was 0.846 (95% CI 0.795-0.898), and a calibration chart indicated good consistency between values predicted by the nomogram and actual observed values. Conclusions:DWI lesions are an independent risk factor for a poor outcome in patients with ICH-particularly symptomatic DWI lesions. A nomogram model based on clinical characteristics and DWI lesions exhibited good efficacy when predicting the outcome of ICH.

Objective:To explore the influence and its mechanism of allogeneic dermal papilla cells (DPCs) on the wound healing of full-thickness skin defects in mice.Methods:This study was an experimental study. DPCs were isolated from the whisker follicles of five 6-week-old male C57BL/6J mice by combining microdissection with collagenase digestion and were successfully identified. Eighteen 8-week-old male C57BL/6J mice were divided into phosphate buffer solution (PBS) group and DPC group according to the random number table, with 9 mice in each group, and the full-thickness skin defect wound model was created on the back of all mice. On day 2, 4, and 6 after injury, the mice in DPC group were administered 100 μL of cell suspension containing 1×10 6 DPCs of the 4 th passage by subcutaneous injection around the wound, and the mice in PBS group was administered an equal volume of PBS. On day 3, 7, 10, and 14 after injury, the wound healing and hair growth of mice in two groups were observed, and the residual wound area was measured, and the hair coverage area on the wound of mice in two groups was measured on day 14 after injury. On day 14 after injury, the wound tissue samples of mice in two groups were collected. Hematoxylin-eosin staining was performed to observe the condition of newborn hair follicles and the number was counted, Masson staining was performed to observe the collagen deposition in the dermis and the collagen deposition area was measured, the immunofluorescence method was used to detect the protein expressions of Wnt/β-catenin signaling pathway related molecules β-catenin and lymphoid enhancer binding factor 1 (Lef1), and Western blotting and real-time fluorescence quantitative reverse transcription polymerase chain reaction were used to detect the protein and mRNA expressions of β-catenin and Lef1, respectively. The number of samples in each experiment was 3. Results:Compared with those in PBS group, the mice in DPC group had accelerated wound re-epithelialization at each time point after injury, and more hair growth on day 10 and 14 after injury. On day 7, 10, and 14 after injury, the residual wound areas of mice in DPC group were (13.92±2.90), (3.69±1.78), and (1.09±0.14) mm 2, respectively, which were significantly smaller than (26.19±2.06), (10.84±3.59), and (6.75±2.11) mm 2 in PBS group, respectively (with t values of 5.85, 3.09, and 4.63, respectively, P values all <0.05). On day 14 after injury, the hair coverage area on the wound of mice in DPC group was (62±7) mm 2, which was significantly larger than (35±6) mm 2 in PBS group ( t=2.89, P<0.05). On day 14 after injury, compared with those in PBS group, the number of newborn hair follicles in the wound tissue of mice in DPC group was significantly increased ( t=5.43, P<0.05), and the dermal collagen deposition area was significantly reduced ( t=3.56, P<0.05). On day 14 after injury, both the immunofluorescence method and the Western blotting detection showed that the protein expressions of β-catenin (with t values of 5.49 and 4.25, respectively, P values all <0.05) and Lef1 (with t values of 7.50 and 11.54, respectively, P values all <0.05) in the wound tissue of mice in DPC group were significantly higher than those in PBS group; the mRNA expressions of β-catenin and Lef1 in the wound tissue of mice in DPC group were significantly higher than those in PBS group (with t values of 7.68 and 9.67, respectively, P<0.05). Conclusions:DPCs can accelerate the re-epithelialization of full-thickness skin defect wounds in mice by activating Wnt/β-catenin signaling pathway and promote hair follicle regeneration during the process of wound healing.

Objective:To understand the clinical application status of the best evidence for airway clearance in Intensive Care Unit (ICU) patients, analyze the barriers and enablers in the process of evidence application, so as to provide reference for formulating transformation strategies.Methods:The literature on airway clearance in ICU patients was systematically searched in domestic and foreign databases and association websites. The best evidences were summarized based on the included literature, and corresponding review indicators were constructed based on the best evidence for clinical baseline review. From July to August 2022, convenience sampling was used to select 30 nurses and 30 patients from ICU of Union Hospital, Tongji Medical College, Huazhong University of Science and Technology. We conducted barriers and transformation strategy analysis based on the review results.Results:A total of 33 review indicators were formulated. The clinical execution rate of the review indicators was 0 to 100%, with 60.6% (20/33) of the review indicators having a clinical execution rate of <60%. The main barriers were that the specialized team for airway clearance involved great personnel and was difficult to organize, nurses had insufficient awareness and importance of airway clearance knowledge, the department lacked corresponding evaluation tools and equipment, the implementation standards for airway clearance treatment within the department were not sound, and the health education materials for airway clearance were incomplete. The transformation strategy mainly included strengthening leadership support, conducting knowledge training on airway clearance, introducing tools and equipment related to airway clearance, improving the implementation standards of airway clearance and health education materials for airway clearance.Conclusions:There is a significant gap between the best evidence for airway clearance in ICU patients and clinical practice. Timely improvement should be made on relevant barriers to promote the conversion of best evidence into clinical practice and improve patient clinical outcomes.
