Objective:To clarify the content on exercise training in patients with connective tissue disease-associated pulmonary arterial hypertension through a scoping review.Methods:Using the scoping review methodological framework proposed by Arksey and O'Malley as a guide, Chinese and English databases such as PubMed, Embase, Wanfang Data, and China National Knowledge Infrastructure were searched to screen the literature on exercise training for patients with connective tissue disease-associated pulmonary arterial hypertension. The search period was from database establishment to April 30, 2024. Two researchers extracted basic information of the included literature, content of the pre-exercise training assessment, exercise training program, and outcome indicators.Results:A total of 13 articles were included. The content of the pre-exercise training assessment in patients with connective tissue disease-associated pulmonary arterial hypertension was not standardized. The type of exercise training was based on aerobic, resistance and respiratory training, with a focus on home exercise. The main outcome indicators included the 6-minute walk distance, cardiopulmonary function, quality of life, and muscle strength.Conclusions:There are various types of exercise training for patients with connective tissue disease-associated pulmonary arterial hypertension, which are safe and feasible. Future research should focus on conducting home-based exercise training programs and constructing core outcome indicators to assess the effectiveness of exercise training.

Objective:To compare bowel preparation quality between 2.0 L and 1.5 L polyethylene glycol (PEG) regimens with optimized dietary restrictions.Methods:This study was a randomized controlled trial conducted in three hospitals: the First Affiliated Hospital of Naval Medical University ( n=57), Huadong Hospital Affiliated to Fudan University ( n=30), and General Hospital of Northern Theater Command ( n=30) from May 5th to 30th, 2024. Participants consumed food for special medical purpose one day before examination or therapeutic colonoscopy and were randomized to receive either 2.0 L PEG (group A) or 1.5 L PEG (group B). Outcomes included the completion rate of bowel preparation, the adequate/excellent bowel preparation rate, Boston bowel preparation scale scores, the subject/endoscopist satisfaction, the willingness to repeat the preparation regimen, and incidence of adverse events. Results:A total of 60 subjects in group A and 57 in group B were included. There was no significant difference in baseline characteristics between the two groups ( P>0.05). The adequate bowel preparation rate [81.7% (49/60) VS 64.9% (37/57), χ2=4.21, P=0.040] and endoscopist satisfaction [88.3% (53/60) VS 70.2% (40/57), χ2=5.91, P=0.015] in group A were significantly higher than those in group B. There were no significant differences in bowel preparation completion rates, the excellent bowel preparation rate, the bowel preparation score, subject satisfaction, willingness to repeat the preparation regimen, or incidence of adverse events ( P>0.05). Conclusion:When combined with optimized dietary restrictions, 2.0 L PEG provides superior bowel preparation quality compared with 1.5 L PEG.

Objective To explore the evaluation value of serum follistatin like protein 1(FSTL1)and glu-cose regulatory protein 78(GRP78)on disease severity and readmission in elderly patients with chronic ob-structive pulmonary disease(COPD).Methods A total of 100 elderly COPD patients(COPD group)treated in this hospital from March 2020 to May 2023 were selected as COPD group,and were divided into grade Ⅰ(35 cases),grade Ⅱ(46 cases)and grade Ⅲ(19 cases)according to the severity of the disease.Another 100 elderly volunteers who underwent physical examination during the same period were selected as the control group.Serum FSTL1 and GRP78 levels were detected by enzyme-linked immunosorbent assay(ELISA).Spearman and Pearson correlation were used to analyze the correlation between serum FSTL1 and GRP78 lev-els and general data.The evaluation value of serum FSTL1 and GRP78 levels in COPD patients on disease se-verity and readmission was analyzed by receiver operating characteristics(ROC)curve.Results Compared with the control group,serum levels of FSTL1 and GRP78 in COPD group were significantly increased(P＜0.05).Serum levels of FSTL1 and GRP78 in COPD patients increased with the severity of the disease(P＜0.05).Compared with non-readmission group,the serum levels of FSTL1 and GRP78 in readmission group were significantly increased(P＜0.05).Spearman correlation analysis showed that serum FSTL1 and GRP78 levels were positively correlated with smoking history,hypertension history and disease severity(P＜0.05).Pearson correlation analysis showed that serum FSTL1 and GRP78 levels were negatively correlated with arte-rial oxygen pressure(PaO2),the ratio of forced expiratory volume in the first second to forced vital capacity(FEV1/FVC),and the percentage of forced expiratory volume in the first second to expected value(FEV1％pred),with significance(P＜0.05),while it was positively correlated with the partial pressure of carbon diox-ide(PaCO2),with significance(P＜0.05).ROC curve analysis showed that serum FSTL1,GRP78 and their combined assessment of disease severity and readmitted area under the curve(AUC)were higher in COPD pa-tients,and the combination was significantly better than the single assessment(P＜0.05).Conclusion Serum levels of FSTL1 and GRP78 are significantly increased in COPD patients,which are correlated with the severi-ty of the disease and have a high value in evaluating the severity of the disease and readmission.

Objective:To observe the feelings of listening to music and the importance of music in the daily life of post-lingual deaf adults with cochlear implants, and to explore the relevant influencing factors.Methods:This was a cross-sectional survey study. From January 2021 to August 2021,the Music-Related Quality of Life Scale was used to evaluate the music needs and music experiences of 63 post-lingual deaf adults who met the inclusion criteria, including 27 males and 36 females, aged (40.7±12.3) years, at the time of surgery (36.8±13.1) years, and with a preoperative hearing aid ineffective time of (3.9±5.8) years. Indicators analyzed included age, duration of ineffective preoperative hearing aid wear, preoperative music preference, duration of postoperative cochlear implant use, current hearing aid modality, and auditory rehabilitation outcomes. Whether the six factors mentioned above constituted an influence on the subjects′ music listening was investigated using SPSS 25.0 statistical software.Results:All of the observations in the scale were correlated with a single factor. The two sub-dimensions of music experience section were related to the effect of auditory rehabilitation. In the importance section, the effect of auditory rehabilitation was the influential factor of the dimension of "participation importance", and the preoperative enjoyment of music was the relevant influential factor of the dimension of "perceived importance". There was a significant difference between the groups when they were grouped by the above factors ( P value<0.05), while there was no statistically significance between the groups when they were grouped by other factors ( P value>0.05). Conclusions:Post-lingual deaf adults show the need and attempt to listen to music after cochlear implantation. The effectiveness of auditory rehabilitation and the degree of music preference preoperatively are two important factors that influence music listening in implant recipients. Once the level of auditory communication has been restored to a certain degree, it is important to pay more attention to the needs of music for implant recipients and train them in time, especially for those with music preferences preoperatively.

Objective To compare the safety and efficacy of direct thrombectomy versus bridging thrombectomy in the treatment of acute anterior circulation large vessel occlusion stroke under different collateral circulation statuses.Methods Totally 93 patients with acute anterior circulation ischemic stroke admitted to the First Affiliated Hospital of Xinxiang Medical University from September 2020 to March 2023 were selected as the research subjects.Patients were divided into direct throm-bectomy group(n=47)and bridging thrombectomy group(n=46)based on the type of thrombectomy.Patients in the direct thrombectomy group received direct intravascular thrombectomy,while patients in the bridging thrombectomy group received intravenous thrombolysis with alteplase combined with mechanical thrombectomy.According computed tomography angiography,the collateral circulation Tan classification was applied to divide the patients into good collateral circulation sub-group and poor collateral circulation sub-group.The modified thrombolysis in cerebral infarction grading(mTICI)was used to evaluate vessel recanalization.Head computed tomography plain scan was performed at 24-48 hours postoperatively to assess if there was hemorrhagic transformation,and modified Rankin Scale score was performed at 90 days postoperatively.Information such as imaging examination time,femoral artery puncture time,vessel recanalization time after thrombectomy,prognosis and spontaneous non-traumatic symptomatic intracerebral hemorrhage(SICH)were collected.Results The age,gender,baseline Alberta stroke program early computed tomography score,baseline national institutes of health stroke scale score,proportions of hypertension,diabetes and atrial fibrillation,baseline systolic pressure,creatinine,baseline blood glucose,platelet count,occlusion site,stroke etiologies and collateral circulation status of patients in the two groups were not statistically significantly different(P＞0.05).There were no significant differences in the post-admission imaging examination time,femoral artery puncture time,vessel recanalization time after thrombectomy,successful vascular reperfusion rate,good prognosis rate,mortality rate,and SICH incidence between the two groups(P＞0.05).The hemorrhagic transformation rate of patients in the direct thrombectomy group was significantly lower than that in the bridging thrombectomy group(P＜0.05).There were no significant differences in the post-admission imaging examination time,femoral artery puncture time,vessel recanalization time after thrombectomy,successful vascular reperfusion rate,good prognosis rate,mortality rate,and SICH incidence between patients with good collateral circulation and patients with poor collateral circulation in the two groups(P＞0.05).The hemorrhagic transformation rate of patients with good and poor collateral circulation in the direct thrombectomy group was significantly lower than that in the bridging thrombectomy group(P＜0.05).Conclusion Under different collateral circulation conditions,the safety and efficacy of direct thrombectomy and bridging thrombectomy in the treatment of acute anterior circulation large vessel occlusion stroke are similar,but bridging thrombectomy is more likely to result in cerebral hemorrhage transformation compared with direct thrombectomy.

Vaccination is a main measure for protecting chickens against Marek's disease,while it is not able to suppress the infection,proliferation,transmission,and virulence enhancement on Marek's disease virus.Inhibiting the proliferation of Marek's disease virus in chicken is therefore an im-portant option for enhancing defense effectiveness.In this study,a compound,DUBs-IN-1,was found to inhibit the activity of MDV049,a protease encoded by Marek's disease virus,via screening a protease inhibitor library using MDV049 as target and ubiquitin probe.Molecular docking re-vealed that DUBs-IN-1 can interact with the residues which formed the catalytic pocket of MDV049,blocking the interaction between Ub substrate and the catalytic center of MDV049,then suppress the activity of MDV049 with competitive inhibition.Using the CPE model,it was found that DUBs-IN-1 at the concentration of 0.35 and 0.70 μmol/L significantly inhibited the CPE in-duced by Marek's disease virus in CEF cells.Quantitative analysis revealed that DUBs-IN-1 inhibi-ted the proliferation of Marek's disease virus in CEF cells(P＜0.01).Furthermore,it was found that the administration of 80 and 150 pg/(kg·d)of DUBs-IN-1 in chicken infected by Marek's disease virus significantly inhibited the proliferation of MDV in T cells(P＜0.01).In summary,this study demonstrated that the compound DUBs-IN-1 is able to inhibit the proliferation of Marek's disease virus in chicken cells,laying a theoretical and practical foundation for further de-velopment of the drugs against Marek's disease virus.

Objective To explore the relationship between collateral circulation and the prognosis of acute ischemic stroke(AIS)patients with successful recanalization after mechanical thrombectomy.Methods A total of 75 AIS patients who received mechanical thrombectomy at the First Affiliated Hospital of Xinxiang Medical University from September 2020 to May 2022 were selected as the research subjects.The clinical data of the patients were collected.According to the modified Rankin scale(mRS)score at 90 days after operation,the patients were divided into the good prognosis group(mRS score≤2)and the poor prognosis group(mRS score ≥3).Univariate and multivariate logistic regression were used to analyze the factors affecting the prognosis of AIS patients with successful recanalization after mechanical thrombectomy.There were three types of collateral circulation:symmetrical collateral circulation,malignant collateral circulation,and other collateral circulation.The National Institutes of Health Stroke Scale(NIHSS)score at admission,the NIHSS score at discharge and changes of the NIHSS score of patients with different collateral circulations were compared.Results Among the 75 patients,43 had a good prognosis,and 32 had a poor prognosis.The incidence of poor prognosis was 42.67％.Univariate analysis showed that history of diabetes,time from onset to puncture(OPT),collateral circulation and NIHSS score were the factors effecting the prognosis of AIS patients with successful recanalization after mechanical thrombectomy(P＜0.05).Age,sex,history of atrial fibrillation,history of hypertension,history of smoking,history of stroke,thrombolytic therapy and modified thrombolysis in cerebral infarction grade were not related to the prognosis of AIS patients with successful recanalization after mechanical thrombectomy(P＞0.05).Multivariate logistic regression analysis showed that symmetrical collateral circulation,malignant collateral circulation,history of diabetes and OPT were independent influencing factors for the prognosis of AIS patients with successful recanalization after mechanical thrombectomy(P＜0.05).There was no significant difference in the admission NIHSS score among the patients with different collateral circulations(P＞0.05).The discharge NIHSS score of patients with symmetrical collateral circulation was significantly lower than that of patients with malignant collateral circulation,and the change in the NIHSS score was more significant than that of patients with malignant collateral circulation(P＜0.05).There was no significant difference in the discharge NIHSS score and change in the NIHSS score between patients with symmetrical collateral circulation and patients with other collateral circulation(P＞0.05),and between patients with malignant collateral circulation and patients with other collateral circulation(P＞0.05).Conclusion Symmetrical collateral circulation,malignant collateral circulation are independent factor affecting the prognosis of AIS patients with successful recanalization after mechanical thrombectomy.Symmetrical collateral circulation may help improve the neurological function of patients after mechanical thrombectomy,and malignant collateral circulation may lead to deterioration of neurological function in patients undergoing mechanical thrombectomy.

Objective:To investigate the changes in total radioactivity in patient body with differentiated thyroid carcinoma (DTC) after 131I treatment and the factors influencing its metabolism. Methods:The clinical data from 218 patients after DTC treatment in the Department of Nuclear Medicine, the Second Affiliated Hospital of Air Force Medical University from September 2021 to April 2022 were retrospectively analyzed. Based on administrated 131I dose, 171 patients were divided into low-dose group (≤ 3.7 GBq) and 47 into high-dose group (>3.7 GBq) . A whole body dynamic radiation monitoring system was used to measure the in vivo residual activity of 131I 24, 48 and 72 h after 131I administration and to explore their influencing factors. Results:24, 48 and 72 h after adimination of 131I, the residual activity of 131I in the low-dose group patients was significantly lower than in the high-dose group patients ( t= -7.46, -3.31, -2.01, P<0.05) . The discharge compliance rate at 24 and 48 h in the low-dose group was significantly higher than that in the high-dose group (21.0% vs. 4.3%, 98.2% vs. 89.4%, χ2 = 7.23, 5.91, P<0.05) , and all patients could meet the discharge criteria at 72 h. Univariate analysis showed that the residual 131I activity at 24 and 48 h was dependent on age, body mass index (BMI) , basal metabolism rate (BMR) and thyroid stimulating hormone (TSH) . As have been shown by multiple linear regression analysis, in the low-dose group, the older age, the higher BMR and the higher TSH level at 24 h tended to the higher 131I residual activity in the body. At 48 h, the higher BMI and the higher TSH level lead to the higher 131I residual activity in patient body. Meanwhile, in the high-dose group, the higher age and BMR at 24 h, tended to the higher in vivo131I residual activity. The influencing factors were analyzed in terms that 131I residual activity reaching 400 MBq in patient body at 24 and 36 h. The result showed that at 24 h the lower TSH level leaded to the lower 131I residual activity in patient body. At 36 h, the younger age, the lower TSH level, and the smaller 131I treatment dose tended to the lower in vivo131I residual activity. Conclusions:Age, BMI, BMR and TSH levels are the influencing factors for the change in total activity in patient body after 131I treatment of DTC. Radiation dose assessment based on the above indicators can provide a reference for adjusting the length of hospitalization time.
