Objective To explore the application value of popaverine combined with stage rehabilitation for patients after free flap grafting for hand trauma.Methods Data of postoperative patients who underwent hand trauma from January 2021 to January 2022 in The 903rd Hospital of the Joint Logistics Support Force of the People's Liberation Army of Chinawere retrospectively collected,and they were divided into the combined rehabilitation group(poppadine combined with stage rehabilitation care)and the stage rehabilitation group(only stage rehabilitation care was applied)according to the treatment methods.Visual analog scale(VAS)scores,rehabilitation exercise adherence scores,postoperative rates of excellent cutaneous sensory function of the hand,total active mobility(TAM)of the fingers,Jamar grip strength,upper extremity functional assessment(DASH)scale scores,and the incidence of vascular crises were compared between the two groups.Results A total of 120 cases were included in the study,with 57 cases in the combined rehabilitation group and 63 cases in the stage rehabilitation group.There was no statistically significant difference in VAS scores,Jamar grip strength and DASH scores between the two groups before surgery(P＞0.05);at 14 days and 3 months of intervention,VAS scores of the two groups decreased compared with the pre-intervention period(P＜0.05),and VAS scores of the patients in the combined rehabilitation group were significantly lower than those in the stage rehabilitation group(P＜0.05).After 3 months of intervention,the rehabilitation exercise adherence score,the rate of excellent hand skin sensory function,and finger TAM of the patients in the combined rehabilitation group were higher than those in the stage rehabilitation group(P＜0.05);Jamar grip strength were elevated in both groups compared with the pre-intervention period,but the combined rehabilitation group were higher than those in the stage rehabilitation group(P＜0.05);DSAH scores were lower in both groups compared to pre-intervention,and were lower in the combined rehabilitation group than in the stage rehabilitation group;and during the 3 months of intervention,the incidence of vascular crisis was significantly lower in patients in the combined rehabilitation group than in the stage rehabilitation group(P＜0.05).Conclusion Opium poppy alkaloids combined with stage rehabilitation can effectively reduce patients'postoperative pain,enhance patients'adherence to rehabilitation exercises,effectively improve postoperative hand function and upper limb motor function,and reduce the incidence of vascular crisis.

Objective:To investigate the change of chemical exchange saturation transfer (CEST) imaging in the bilateral substantia nigra (SN) and red nucleus (RN) of Parkinson disease (PD), and to explore the value of CEST-MRI for the clinical application of PD.Methods:This was a cross-sectional study. A total of 45 PD patients (PD group) and 21 sex-, age-, and cognitive-function matched normal control subjects (NC group) were retrospectively enrolled from December 2012 to July 2015 in Beijing Hospital. All subjects underwent brain CEST-MRI and routine MRI. Based on the MATLAB software package, the 4-pool Lorentz fitting model was applied to analyze the signal change of CEST imaging, which could acquire the mean amplitudes of the 4-pool parameters including Amide, nuclear overhauser enhancement (NOE), direct water saturation (DS) and magnetization transfer (MT) in the bilateral SN and RN. Independent samples t test and Mann-Whitney U test were used to compare CEST parameters between the PD group and the NC group and controlled by Bonferroni correction. The combined model was constructed based on parameters with inter-group differences after correction. The receiver operating characteristic curve and area under the curve (AUC) were used to evaluate the diagnostic efficiency of the CEST parameters and the combined model. Results:Compared with the NC group, the left SN Amide value, left RN Amide value, and right SN NOE value were reduced in the PD group, and the difference was statistically significant ( t=-3.59, corrected P=0.026; t=-3.77, corrected P=0.016; Z=-3.27, corrected P=0.017). The left SN Amide value, the left RN Amide value, the right SN NOE value, and the combined model all had good diagnostic efficacy in the differentiation of the PD group from the HC group (AUCs of 0.78, 0.79, 0.75, and 0.81, respectively). The combined model had the highest AUC value (0.81) and specificity (97.78%), the Amide value of left SN had the highest sensitivity (93.33%). Conclusions:Quantitative analysis of CEST-MRI based on the 4-pool Lorentz fitting model shows significant differences in the CEST quantitative indicators of the SN and RN between the PD group and the NC group, demonstrating good potential for clinical application in the diagnosis of PD.

Nucleotide-binding oligomerization domain 1 (NOD1), a cytosolic pattern recognition receptor protein, plays a crucial role in innate immune responses. However, the functional expression of NOD1 in mesenchymal stem cells (MSCs) derived from endometriosis remains unclear. The aim of this study was to explore the functions of NOD1 in ectopic endometrial lesions. Tissues and MSCs were isolated from both normal endometrium and endometriosis.Immunohistochemistry and real time quantitative polymerase chain reaction (RT-qPCR) were used to determine the expression of NOD1 in the tissues/MSCs. Quantification of various cytokines was performed using RT-qPCR and enzyme-linked immunosorbent assay. To confirm the proliferation, invasion/migration, and apoptotic viabilities of the samples, Cell Counting Kit-8, clonogenic formation, transwell assays, and apoptotic experiments were conducted.Higher levels of NOD1 expression were detected in the ectopic-MSCs obtained from endometriosis compared to those from the endometrium. The expression of interleukin-8 was higher in the ectopic-MSCs than in the eutopic-MSCs.Pretreatment with NOD1 agonist significantly enhanced the proliferation and invasion/migration of eutopic-MSCs.Additionally, the NOD1 inhibitor ML-130 significantly reduced the proliferation, clone formation, invasion, and migration abilities of the ectopic-MSCs, having no effect on their apoptosis capacity. Our findings suggest that the expression of NOD1 in ectopic-MSCs may contribute to the progression of ectopic endometrial lesions.

Objective:To investigate the safety and efficacy of Belintoumab on the treatment of children with acute B-lymphoblastic leukemia (B-ALL).Methods:The clinical data of 10 children with CD 19+ B-ALL who were admitted to the Department of Pediatrics, the First Affiliated Hospital of Zhengzhou University from September 2021 to May 2022 and treated with Belintoumab were analyzed retrospectively. Results:Among the 10 cases, there were 6 recurrent cases, 3 cases with persistent minimal residual disease (MRD) positive after an initial treatment, and 1 case complicated with invasive candidiasis.Before treatment, bone marrow blasts ≥0.25, and that ranged 0.05-<0.25 were detected in 2 cases and 1 case, respectively.Seven cases had a complete remission (CR) of bone marrow, 6 of which were MRD positive and 1 case was MRD negative.After treatment with Belintoumab, the CR rate was 66.7% (2/3). The overall MRD negative rate was 88.9% (8/9), and the negative rate in previously MRD positive children was 100% (6/6). The median follow-up time was 4.1 (1.6-10.0) months after the application of Belintoumab.The overall survival (OS) rate was 70.0% (7/10). Eight MRD negative children received hematopoietic stem cell transplantation, and the OS rate was 75% (6/8). Survived children did not relapse until the last follow-up visit.Fever (90%, 9/10) was the most common adverse events, followed by neutropenia (90%, 9/10). One case (10%, 1/10) of neurotoxicity was seizures (grade 2) and one case (10%, 1/10) suffered cytokine release syndrome (grade 2), which did not influence the therapeutic efficacy of Belintoumab after symptomatic treatment.Conclusions:Belintoumab is safe and effective on the treatment of children with recurrent/refractory CD 19+ B-ALL, and those with MRD positive who have achieved CR in bone marrow have a higher rate of turning negative.Belintoumab can also be used as a bridge scheme for CD 19+ B-ALL children who cannot tolerate chemotherapy.

Objective:To investigate the incidences of metachronous advanced adenoma (MAA) in patients with simultaneous multiple primary colorectal cancer (CRC) and patients with sporadic CRC.Methods:From January 1, 2008 to September 30, 2022, at Beijing Shijitan Hospital, Capital Medical University, CRC patients who underwent surgery and 3 years follow-up with endoscopy were enrolled. The patients completed colonoscopy at least 2 times during follow-up in 6 to 36 months after surgery, and the interval between the 2 times colonoscopies was over 6 months. Clinical data including age, gender, and tumor location, stage, pathological features, combined underlying diseases, preoperative carcinoembryonic antigen, hemoglobin and other laboratory results, baseline colonoscopy results, and detection of MAA were collected. According to age (±2 years old), gender, location of primary lesion and stage of tumor, patients with simultaneous CRC or sporadic CRC were matched at 1∶1 ratio by propensity score matching. The cumulative risks of MAA in patients with simultaneous multiple primary CRC and patients with sporadic CRC were calculated. Cox proportional hazard regression was used to analyze the influencing factors in the occurrence of MAA.Results:A total of 814 CRC patients were enrolled and matched. After paired matching, there were 36 cases of simultaneous multiple primary CRC (78 lesions) and 78 cases of sporadic CRC (78 lesions). The cumulative incidences of MAA at 1, 2 and 3 years of simultaneous CRC group were 11.1%(4/36), 22.2%(8/36) and 33.3%(12/36), respectively. The cumulative incidences of MAA at 1-, 2- and 3-year of sporadic CRC group were 3.8%(3/78), 12.8%(10/78) and 20.5%(16/78), respectively.Simultaneous CRC was correlated with an increase in the 3-year cumulative incidence of MAA ( HR=4.163, 95% confidence interval(95% CI) 1.032 to 4.721, P=0.047). Especially in left-sided CRC, the risk of MAA in simultaneous CRC increased ( HR=7.186, 95% CI 1.602 to 20.787, P=0.010). The results of multivariate cox-regression analysis indicated that detection of simultaneous advanced adenoma at baseline endoscopy was an independent risk factor of MAA ( HR=3.175, 95% CI 1.411 to 7.142, P=0.005). Conclusion:Colouoscopy follow-up should be strengthened in patients with simultaneous multiple primary CRC and simultaneous advanced adenomas.

Objective To investigate the value of Baveno Ⅶ criteria versus Expanded Baveno Ⅶ criteria in screening for high-risk varices (HRV) in patients with compensated advanced chronic liver disease (cACLD). Methods A total of 146 patients with cACLD who were admitted to Beijing Shijitan Hospital, Capital Medical University, from January 2016 to December 2018 were enrolled, and according to the absence or presence of HRV based on gastroscopy, they were divided into HRV group with 68 patients and control group with 78 patients. Clinical data, liver stiffness measurement (LSM), and gastroscopy findings were analyzed, and different Baveno Ⅶ criteria were analyzed in terms of their sensitivity and specificity in the diagnosis of HRV. The Mann-Whitney U test and the McNemar test were used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. A univariate logistic regression analysis was performed for the variables used to predict HRV, and a multivariate analysis was performed for the variables with P < 0.1. The two sets of Baveno Ⅶ criteria were compared in terms of their sensitivity and specificity in the diagnosis of HRV. Results A total of 146 patients were enrolled in the study, among whom 68 (46.6%) were found to have HRV. The median age was 54 years (range 29-84 years), male patients accounted for 65.8%, and hepatitis B virus was the main etiology observed in 115 patients (78.8%). The univariate logistic regression analysis showed that LSM and platelet count (PLT) were associated with HRV (both P < 0.05). The multivariate analysis showed that based on Baveno Ⅶ criteria, LSM > 20 kPa or PLT < 150×10 9 /L was associated with HRV (both P < 0.05), and based on Expanded Baveno Ⅶ criteria, LSM > 25 kPa or PLT < 110×10 9 /L was associated with HRV (both P < 0.05). LSM and PLT had an area under the ROC curve of 0.797 (95% confidence interval [ CI ]: 0.723-0.859) and 0.789 (95% CI : 0.714-0.852), respectively, in the diagnosis of HRV. There were significant differences in the prevalence rates of esophageal and gastric varices and HRV between the patients who met Baveno Ⅶ criteria and those who did not meet such criteria ( χ 2 =23.14 and 23.14, both P < 0.001), as well as between the patients who met Expanded Baveno Ⅶ criteria and those who did not meet such criteria ( χ 2 =43.51 and 25.71, both P < 0.001). Although a higher proportion of patients were exempted from gastroscopy based on Expanded Baveno Ⅶ criteria (32.9% vs 13.7%), Baveno Ⅶ criteria had higher sensitivity (0.98 vs 0.88) and negative predictive value (0.95 vs 0.83) and could better avoid the missed diagnosis of HRV (1.0% vs 9.3%). Conclusion Baveno Ⅶ criteria are more suitable for the screening for HRV in cACLD patients in China.

Objective To investigate the effect of ultrasound-guided bilateral superior laryngeal nerve internal branch block combined with endotracheal surface anesthesia in patients with hypertensive cerebral hemorrhage for the duration of postoperative tube insertion.Methods A total of 100 emergency hypertensive intracerebral hemor-rhage surgical patients who visited our hospital from October 2021 to April 2023 were included as the research subjects.They were randomly divided into four groups,25 patients in each group.After surgery,group U received bilateral superior laryngeal nerve internal branch block under guidance of ultrasound combined with endotracheal surface anesthesia,group C1 received bilateral superior laryngeal nerve internal branch block under guidance of ultrasound,group C2 received endotracheal surface anesthesia,and group C3 did not undergo any procedure after surgery.Hemodynamic changes(HR,MAP,and SpO2)at different time points during the postoperative tube insertion in four groups of patients were recorded.The frequency of restlessness within 10 hours after surgery,the dosage of dexmedetomidine and urapidil,the volume of wound drainage,and the satisfaction of bed nurses were also recorded.Results There was no statistically significant difference in general conditions among the four groups(P>0.05).There was no statistically significant difference in HR and MAP at different time points in Group U(P>0.05),while the differences among the other three groups were statistically significant(P<0.05).At the same time point,the MAP and HR of group U and C1 were significantly lower than those of group C3(P<0.05),and the MAP of group U was significantly lower than that of group C2(P<0.05).There was no statistical difference in SPO2 among the four groups of patients at the same time point(P>0.05);The frequency of restlessness,dosage of dexmedetomidine and urapidil,and volume of wound drainage in the U and C1 groups were significantly lower than those in the C2 and C3 groups(P<0.05).Except for the difference in restlessness frequency(P<0.05),there was no statistical difference in other indicators between group U and C1;There was a statistical difference in satisfaction among the four groups of nurses(P<0.05,C3>C2>C1>U group).No nerve block related complications were observed in the U and C1 group.Conclusion Ultrasound-guided bilateral superior laryngeal nerve branch block combined with endotracheal surface anesthesia can maintain hemodynamics steadily of the postoperative patients in the NICU to varying degrees and reduce the frequency of postoperative restlessness,the dosage of sedative and anti-hypertensive drugs,while reducing the flow of wound drainage,and improve the satisfaction of bed nurses.

Objective:To investigate the grey matter alterations of Parkinson′s disease (PD) patients with and without sleep disorders, and to explore the relationship between different sleep-related problems and clinical variables as well as grey matter volume (GMV) in PD.Methods:Forty-six PD patients and 38 healthy controls (HCs) were recruited from January 2018 to December 2021 in the Department of Neurology, Beijing Hospital. PD patients were divided into PD with sleep disorders (PD-S, n=26) and PD without sleep disorders (PD-nS, n=20) subgroups (cutoff points of 82 for Parkinson′s Disease Sleep Scale or less than 5 for each item was considered as an indicator of substantial sleep disorder). The Mini-Mental State Examination (MMSE), the third part of the Unified Parkinson′s Disease Rating Scale (UPDRS-Ⅲ), Hamilton Rating Scale for Anxiety (HAMA), Hamilton Rating Scale for Depression (HAMD), Non-Motor Symptoms Questionnaire (NMSQ), and Parkinson′s Disease Questionnaire-39 (PDQ-39) were used to evaluate cognitive function, motor symptoms, anxious and depressive symptoms, non-motor symptoms, and the quality of life of the patients. Optimized voxel-based morphometry was applied to the magnetic resonance imaging brain images in all participants,and multiple linear regression analysis was used to test the correlation between GMV and sleep quality in patients with PD. Results:Compared with the HCs, PD-nS patients showed decreased GMV in bilateral limbic lobe, parahippocampal gyrus, amygdala, cingulate gyrus, hippocampus, right cerebellum, bilateral frontotemporal lobe, bilateral occipital lobe and the left parietal lobe. PD-S group exhibited reduced GMV in bilateral limbic lobe, parahippocampal gyrus, amygdala, right cerebellum, bilateral frontotemporal lobe and bilateral parietal-occipital lobe, compared to the HCs. Compared with PD-nS, PD-S patients revealed higher depressive (HAMD score: 12.19±5.59 vs 6.95±3.19, t=-4.01, P<0.001), anxious (HAMA score: 12.04±5.32 vs 7.25±4.68, t=-3.18, P=0.003), and non-motor symptoms scores (NMSQ score: 12.92±5.18 vs 9.90±4.10, t=-2.14, P=0.038), poorer quality of life (PDQ-39 score: 35.31±22.01 vs 22.40±9.00, t=-2.71, P=0.010), and reduced GMV in the left insula, frontal, and parietal lobe ( P<0.001, uncorrected, cluster>100). There was a marked relationship between sleep quality and the reduced GMV of the right medial temporal gyrus (β=0.006, 95% CI 0.002-0.010, P=0.003), left middle frontal gyrus (β=0.006, 95% CI 0.002-0.010, P=0.002), the right cerebellum (β=0.014, 95% CI 0.005-0.023, P=0.003), and the right medial occipital gyrus (β=0.017, 95% CI 0.011-0.024, P<0.001). Significant grey matter changes were associated with nocturnal restlessness, mainly within the left limbic lobe, bilateral occipital lobe, the right cerebellum, and parietal lobe (β=0.008, 95% CI 0.006-0.010, P<0.001). Furthermore, nocturia in PD was related to certain grey matter atrophy, including bilateral limbic lobe, the right inferior parietal gyrus, and bilateral frontal lobe (β=0.010, 95% CI 0.008-0.013, P<0.001). The symptom of daytime dozing was correlated with GMV reduction in the right occipital lobe, the left temporal lobe (β=0.014, 95% CI 0.010-0.019, P<0.001). There were also several compensatory brain regions, including bilateral frontal lobe, the left limbic lobe and cingulate ( P<0.001, uncorrected, cluster>60). Conclusions:Sleep disturbance is common in PD, which is related to the anxious and depressive symptoms, non-motor symptoms, and the quality of life. PD patients with different sleep disorders show grey matter alterations in severeal brain regions, which are associated with sleep quality, nocturnal restlessness, psychosis, and daytime dozing.

Objective:To explore whether the regular feedback system in opportunistic screening of colorectal cancer can improve the adenoma detection rate (ADR) of endoscopists.Methods:This study was an observational study, divided into three stages: the baseline stage before intervention (the pre-intervention period), the regular feedback stage (the intervention period) and the post-intervention stage (the post-intervention period). In the pre-intervention period, all patients who underwent opportunistic screening of colorectal cancer in Department of Gastroenterology in Beijing Shijitan Hospital Affiliated to Capital Medical University from June 2017 to May 2018 were reviewed, and the ADR of each endoscopist was calculated. In the intervention period from June 2018 to November 2018, colonoscopies were performed on patients for opportunistic screening of colorectal cancer by endoscopists who participated in the feedback. The ADR of each endoscopist during the previous month was calculated at the beginning of each month and feedback was provided in the form of a report. In the post-intervention period from December 2018 to January 2019, colonoscopies were performed on patients for opportunistic screening of colorectal cancer by endoscopists who participated in the feedback. The ADR of each endoscopist was calculated after the feedback stopped. ADR and polyp detection rate (PDR) of three stages were compared.Results:A total of 1 768, 1 308 and 344 patients were enrolled for opportunistic screening of colorectal cancer during the pre-intervention, the intervention and the post-intervention period respectively. Eight endoscopists participated in the whole process of this study. The total ADR increased from 23.70% (419/1 768) in the pre-intervention period to 33.72% (441/1 308) in the intervention period ( χ2=37.449, P<0.05). Two months after intervention, ADR decreased slightly to 33.14% (114/344), but was still higher compared with before ( χ2=13.602, P<0.05). The total PDR increased from 47.17% (834/1 768) in the pre-intervention period to 52.68% (689/1 308) in the intervention period ( χ2=9.111, P<0.05). Two months after the intervention, PDR increased slightly to 53.78% (185/344), and still higher compared with before ( χ2=5.035, P<0.05). Conclusion:Regular feedback to endoscopists can improve ADR in opportunistic screening of colorectal cancer.

Objective:To investigate the characteristics of white matter lesions(WML)found by magnetic resonance imaging(MRI)and the relationship with clinical features in patients with Parkinson's disease(PD).Methods:This was a retrospective study by using a method of MRI T2WI-FLAIR.The WML in 87 PD patients were evaluated by using the Fazekas scale and Scheltens scale.Patients were divided into the early PD group[n=47, Hoehn-Yahr(H-Y)stage 1.0-2.0] vs.the middle-advanced PD group(n=40, H-Y stage 2.5-4.0), the non-depressed PD group(n=71) vs. the depressed PD group(n=16), the non-anxions PD group(n=62) vs.the anxions PD group(n=25). An ordinal regression model was used to investigate the correlations of WML with gender, age, Mini-Mental State Examination(MMSE)score, Unified Parkinson's disease Rating Scale-Ⅲ score(UPDRS-Ⅲ), Hamilton Rating Scale for Depression score(HAMD)and Hamilton Rating Scale for Anxiety score(HAMA). Results:Compared with the early PD group, the middle-advanced PD group showed that the WML were increased in lobe of brain(5.30±4.85 vs. 3.43±3.13, P<0.05), especially in the occipital lobe(0.48±0.99 vs. 0.11±0.31, P<0.05). There was no significant difference in the WML between the non-depressed/anxions and the depressed/anxions PD group.After being evaluated by the Scheltens scale, WML in periventricular hyperintensities(PVH)regions( OR=1.13, P<0.01), in brain lobe( OR=1.10, P<0.01)and in basal ganglia regions( OR=1.15, P<0.01)were correlated with age.WML in the brain besides the PV region were correlated with MMSE score( OR=0.68, P<0.01), especially in posterior horns( OR=0.60, P<0.01)and lateral ventricles( OR=0.68, P<0.05). WML in temporal lobe was correlated with MMSE score( OR=0.68, P<0.05). WML in brain lobe was correlated with H-Y stages( OR=2.10, P<0.05), especially in the occipital lobe( OR=3.33, P<0.05). WML in parietal lobe was associated with HAMD score( OR=1.13, P<0.05). WML in basal ganglia regions was related to diabetes( OR=6.34, P<0.05), especially in the putamen( OR=6.86, P<0.01). After being evaluated by the Fazekas scale, WML in PVH region( OR=1.16, P<0.01)and deep white matter hyperintensities( OR=1.13, P<0.01)were correlated with age.WML in PVH region were associated with MMSE score( OR=0.65, P<0.01). WML scores in PD patients had no correlation with gender, hypertension, coronary heart disease, hyperlipemia, UPDRS-Ⅲ score and HAMA score. Conclusions:The WML is present in PD patients, and it is correlated with age, diabetes, severity of disease, depression and cognitive function.
