Ischemic stroke is the most common type of cerebrovascular disease, which has the characteristics of high morbidity, high disability, and high mortality. Sleep disorder is a common complication after ischemic stroke, which can increase the risk of stroke recurrence and seriously affect the outcome of patients. This article reviews the classification and mechanism of post-stroke sleep disorders, the impact on the outcome of patients, the changes in sleep structure of patients with stroke, and the diagnosis and treatment of post-stroke sleep disorders, in order to improve clinicians' understanding of post-stroke sleep disorders.

Sixty two patients with low anal fistula were treated by anal fistulectomy (fistula group) and 82 patients with mixed hemorrhoids were treated by automatic ligation of hemorrhoids (RPH group) and 38 patients with anal fistula plus mixed hemorrhoids were treated by the RPH and anal fistulectomy (fistula plus RPH group),the clinical data of patients were retrospectively analyzed.The complication rate,the degree of pain and,the urination disorders,the postoperative recurrent rate,scar area and the anal functions were observed and compared.There were no differences in pain degree at d1 and d3 among three groups(P ＞ 0.05).There was significant difference in urination disorders between the fistula group and anal fistula plus RPH group (8％ vs.32％,P ＜ 0.05),but no differences between the RPH group and anal fistula plus RPH group (11％ vs.32％,P ＞ 0.05).There were significant differences in scar area and the anal functions between anal fistula group and anal fistula plus RPH group(P ＜ 0.05).There were no postoperative massive hemorrhage,proctenclisis and infection in all three groups.

Objective: To observe the safety and clinical efficacy of tumor antigen-pulsed dendritic cell(DC) vaccine in treatment of advanced malignant tumor.Methods: Ninety-one patients with non-small cell lung cancer,colon and rectal cancer,melanoma,renal carcinoma,breast cancer and other malignant tumors were enrolled in this study.All patients met the selecting standard and signed informed consent.Human dendritic cells were obtained from peripheral blood monocytes by culturing them with granulocyte macrophage-colony stimulating factor and interleukin-4.DC vaccine was prepared from tumor antigen pulsed immature dendritic cells in vitro.Patients received the vaccine therapy once every week and one cycle was defined as once every week for 3 weeks.Results: All the patients received 96 cycles of DC vaccine treatment.Symptoms of toxicity included fever,shivering,aching pain of muscle,asthenia,itching,stifle and transient fatigue;most of the symptoms automatically recovered.Clinical efficacy of the treatment was evaluated in 76 patients.Thirty-one of the 76 patients were stable after treatment and 45 were in progressive situation,with the clinical benefiting rate being 40.8%.Eighty-five patients were followed up.The median time for progression was 2.6 months;the overall survival time was 0.9-30.6 months;and the median survival period was 4.5 months,with the one year survival rate being 9.2%.Conclusion: The results suggest that the DC vaccine therapy is well tolerated in treating patients with advanced malignant tumors and has satisfactory clinical benefit;the clinical value of DC vaccine therapy needs to be further observed.

Objective To investigate the ATP binding cassette transporter A1 (ABCA1) expression in perihematomal tissue of mouse cerebral hemorrhage model induced by collagenase. Methods Stereotactic injection of type Ⅳ collagenase was used to induce a model of caudate putamen intracerebral hemorrhage in mice. The behavioral scores were use to assess neurological deficits at 24 h, 48 h and 72 h after model making. Neisserian staining was used to detect the morphology of neurons around hematomas.Immunohistochemical staining and Western blot analysis were used to detect the expression of ABCA1 around hematomas. Results Nissl bodies reduction, atrophy, necrosis of perihematomal neurons were observed and aggravated over time. Immunohistochemical staining and Western blot analysis showed that the expression level of ABCA1 in the perihematomal tissue was significantly higher than that in the sham operation group (all P < 0. 05), and the expression level increased significantly with time (all P < 0. 05 ).Conclusion ABCA1 was up-regulated after cerebral hemorrhage, suggesting that it might be involved in the pathological process of cerebral hemorrhage.

Objective To investigate the correlation between serum miR-320b and carotid atherosclerosis in patients with acute ischemic stroke.Methods From January 2017 to December 2017,patients with acute ischemic stroke visited the Department of Neurology,the Affiliated Hospital of Yangzhou University were enrolled.According to the findings of carotid artery ultrasonography,they were divided into plaque group and plaque-free group.The baseline clinical data such as demographic data,vascular risk factors,and blood biochemical indicators were collected.Reverse transcription quantitative polymerase chain reaction was used to detect the expression level of serum miR-320b.Multivariatelogistic regression analysis was used to determine the independent risk factors for carotid atherosclerosis.Results A total of 135 patients with acute ischemic stroke were enrolled in this study,including 58 females and 77 males,aged 58.4 ± 10.6 years.There were 85 patients in the plaque group and 50 in the plaque-free group.The total cholesterol (t =5.523,P =0.023) and low-density lipoprotein cholesterol (t =4.415,P =0.044) in the plaque group were significantly higher than those in the plaque-free group,while high-density lipoprotein cholesterol (t =5.849,P=0.017) and serum miR-320b (t =4.331,P=0.039) were significantly lower than those in the plaque-free group.Multivariate logistic regression analysis showed that referring to the highest quartile group,the low serum miR-320b level might be an independent risk factor for carotid atherosclerosis (the first quartile group:odds ratio 2.701,95％ confidence interval 1.154-6.321,P =0.022;the second quartile group:odds ratio 2.521,95％ confidence interval 1.249-5.091,P =0.010;and the third quartile group:odds ratio 1.849,95％ confidence interval 1.041-3.283,P=0.036).Conclusion The low serum miR-320b level might be an independent risk factor for carotid atherosclerosis in patients with acute ischemic stroke.

Objective:To investigate the clinical effect of rectangular scar flap combined with autologous thinning split-thickness skin graft for repairing type Ⅳ axillary scar contracture deformity after extensive burns.Methods:From January 2015 to January 2019, patients with type Ⅳ axillary scar contracture deformity after extensive burns were admitted to the Department of Skin Wound Repair Center of Wuhan Third Hospital. Rectangular scar flaps were used to reconstruct the axillary area, Y-shaped incision was made on the short side to release the scar, the resulting defects after flap formation were repaired with autologous split-thickness skin grafts. The hyperplasia and contracture of the grafted skin, the size of rectangular scar flap, the appearance of axilla, the growth of residual axillary hair, and the range of motion of shoulder joint were observed during the follow-up of 18 months to 3 years.Results:A total of 6 cases were selected, including 2 males and 4 females, aged from 18 to 58 years, with the duration of scar contracture deformity ranging from 1 to 23 years. The rectangular scar flaps of all 6 patients survived. At the follow-up of 18 months to 3 years, the axillary scar hyperplasia and the skin graft contracture were mild. At 18 months after operation, the function of shoulder joint was restored with 180° shoulder abduction and lifting. Axillary appearance and residual axillary hair growth were satisfactory, the self-care ability and the quality of life of patients improved.Conclusions:Rectangular scar flap combined with autologous thinning split-thickness skin graft is a good method for repairing type Ⅳ axillary scar contracture in patients with lack of autologous skin sources for extensive burns.

Objective:To investigate the value of number of negative lymph nodes (NLNs) in predicting the prognosis of patients with esophageal cancer after neoadjuvant therapy and the construction of nomogram prodiction model.Methods:The retrospective cohort study was conducted. The clinicopathological data of 1 924 patients with esophageal cancer after neoadjuvant therapy uploaded to the Surveillance, Epidemiology, and End Results Database of the National Cancer Institute from 2004 to 2015 were collected. There were 1 624 males and 300 females, aged 63 (range, 23?85)years. All 1 924 patients were randomly divided into the training dataset of 1 348 cases and the validation dataset of 576 cases with a ratio of 7:3 based on random number method in the R software (3.6.2 version). The training dataset was used to constructed the nomogram predic-tion model, and the validation dataset was used to validate the performance of the nomogrram prediction model. The optimal cutoff values of number of NLNs and number of examined lymph nodes (ELNs) were 8, 14 and 10, 14, respectively, determined by the X-tile software (3.6.1 version), and then data of NLNs and ELNs were converted into classification variables. Observation indicators: (1) clinicopathological characteristics of patients in the training dataset and the validation dataset; (2) survival of patients in the training dataset and the validation dataset; (3) prognostic factors analysis of patients in the training dataset; (4) survival of patients in subgroup of the training dataset; (5) prognostic factors analysis in subgroup of the training dataset; (6) construction of nomogram prediction model and calibration curve. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. The Kaplan-Meier method was used to draw survival curve and Log-Rank test was used for survival analysis. The COX proportional hazard model was used for univariate and multivariate analyses. Based on the results of multivariate analysis, the nomogram prediction model was constructed. The prediction efficacy of nomogram prediction model was evaluated using the area under curve (AUC) of the receiver operating characteristic curve and the Harrell′s c index. Errors of the nomogram prediction model in predicting survival of patients for the training dataset and the validation dataset were evaluated using the calibration curve. Results:(1) Clinicopathological characteristics of patients in the training dataset and the validation dataset. There was no significant difference in clinicopatholo-gical characteristics between the 1 348 patients of the training dataset and the 576 patients of the validation dataset ( P>0.05).

Results of multivariate analysis showed that gender, neoadjuvant pathological (yp) T staging, ypN staging (stage N1, stage N2, stage N3) and number of NLNs (8?14, >14) were independent influencing factors for the prognosis of patients with esophageal cancer after neoadjuvant therapy ( hazard ratio=0.65, 1.44, 1.96, 2.41, 4.12, 0.69, 0.56, 95% confidence interval as 0.49?0.87, 1.17?1.78, 1.59?2.42, 1.84?3.14, 2.89?5.88, 0.56?0.86, 0.45?0.70, P<0.05). (4) Survival of patients in subgroup of the training dataset. Of the patients with NLNs in the training dataset, the 3-year cumulative survival rate of patients with number of NLNs as <8, 8?14 and >14 was 61.1%, 71.6% and 76.8%, respectively, and the 5-year cumulative survival rate was 50.7%, 59.9% and 70.1%, respectively. There was a significant difference in the survival of these patients in the training dataset ( χ2=12.66, P<0.05). Of the patients with positive lymph nodes in the training dataset, the 3-year cumulative survival rate of patients with number of NLNs as <8, 8?14 and >14 was 26.1%, 42.9% and 44.7%, respectively, and the 5-year cumulative survival rate was 20.0%, 36.5% and 39.3%, respectively. There was a significant difference in the survival of these patients in the training dataset ( χ2=20.39, P<0.05). (5) Prognostic factors analysis in subgroup of the training dataset. Results of multivariate analysis in patients with NLNs in the training dataset showed that gender, ypT staging and number of NLNs (>14) were independent influencing factors for the prognosis of patients with esophageal cancer after neoadju-vant therapy ( hazard ratio=0.67, 1.44, 0.56, 95% confidence interval as 0.47?0.96, 1.09?1.90, 0.41?0.77, P<0.05). Results of multi-variate analysis in patients with positive lymph nodes in the training dataset showed that race as others, histological grade as G2, ypN staging as stage N3 and number of NLNs (8?14, >14) were independent influencing factors for the prognosis of patients with esophageal cancer after neoadjuvant therapy ( hazard ratio=2.73, 0.70, 2.08, 0.63, 0.59, 95% confidence interval as 1.43?5.21, 0.54?0.91, 1.44?3.02, 0.46?0.87, 0.44?0.78, P<0.05). (6) Construction of nomogram prediction model and calibration curve. Based on the multivariate analysis of prognosis in patients of the training dataset ,the nomogram prediction model for the prognosis of patients with esophageal cancer after neoadju-vant treatment was constructed based on the indicators of gender, ypT staging, ypN staging and number of NLNs. The AUC of nomogram prediction model in predicting the 3-, 5-year cumulative survival rate of patients in the training dataset and the validation dataset was 0.70, 0. 70 and 0.71, 0.71, respectively. The Harrell′s c index of nomogram prediction model of patients in the training dataset and the validation dataset was 0.66 and 0.63, respectively. Results of calibration curve showed that the predicted value of the nomogram prediction model of patients in the training dataset and the validation dataset was in good agreement with the actual observed value. Conclusion:The number of NLNs is an independent influencing factor for the prognosis of esophageal cancer patients after neoadjuvant therapy, and the nomogram prediction model based on number of NLNs can predict the prognosis of esophageal cancer patients after neoadjuvant therapy.

Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.
