RESUMEN
Objective:Of all spontaneous bleeding complications in patients with acute ST-elevation myocardial infarction (STEMI), upper gastrointestinal bleeding (UGIB) is the most common and of specific interest, because it can be prevented by several prophylactic measures. The purpose of this study was to investigate the in-hospital incidence, associated outcomes, and predictors of UGIB after STEMI.Methods:In this retrospective study, we analyzed the records of 2 791 patients with acute STEMI admitted to Beijing Anzhen Hospital Affiliated to Capital Medical University between January 2018 and January 2022. The patients were divided into the UGIB group ( n=61) and non-UGIB group ( n=2 730) according to the presence or absence of upper gastrointestinal hemorrhage, respectively. Baseline clinical conditions, coronary lesions, in-hospital deaths, and in-hospital adverse events were compared between the two groups. Logistic regression analysis was also performed for risk factors that could lead to UGIB. Results:The in-hospital incidence of UGIB after STEMI was 2.2% (61/2 791). Hospital stay was significantly longer in the UGIB group [8(6, 12) days vs. 5 (4, 7) days, Z=3.28, P<0.001] and in-hospital mortality was significantly higher in the UGIB group than in the non-UGIB group (9.8% vs. 0.8%, χ2=0.63, P=0.001). Patients with UGIB were significantly older than those without UGIB (63±11 years vs. 58±11 years, t=-3.75, P<0.001). The serum creatinine level of UGIB patients was significantly higher than that of non-UGIB patients [(80(62, 98) mmol/L vs. 73(64, 84) mmol/L, Z=1.68, P=0.007], the red blood cell count of UGIB patients was significantly lower than that of non-UGIB patients [4.1(3.8, 4.6)×10 12/L vs. 4.6(4.2, 4.9)×10 12/L, Z=2.61, P<0.001], and the hemoglobin concentration of UGIB patients was significantly lower than that of non-UGIB patients [129(109, 141) g/L vs. 141(130, 152) g/L, Z=2.52, P<0.001]. Brain natriuretic peptide levels were significantly higher in UGIB patients than in non-UGIB patients [331(165, 644) ng/L vs. 181(89, 333) ng/L, Z=2.42, P<0.001]. Logistic regression analysis showed that age ( OR=1.045, 95% CI 1.009-1.082, P=0.013); hemoglobin ( OR=1.594, 95% CI 1.150-2.210, P=0.005); hematocrit ( OR=0.181, 95% CI 0.060-0.546, P=0.002); and mean hemoglobin concentration ( OR=0.845, 95% CI 0.752-0.951, P=0.005) were independent risk factors for UGIB in patients with STEMI. Logistic regression analysis of risk factors for in-hospital death revealed that concurrent UGIB was an independent risk factor for in-hospital death in patients with STEMI ( OR=2.954, 95% CI 0.635-13.751, P=0.024). Conclusions:The incidence of in-hospital UGIB in STEMI patients was 2.2%, and the in-hospital mortality rate of STEMI complicated with UGIB increased to 9.8%. Concurrent UGIB was an independent risk factor for in-hospital death in patients with STEMI. The most important predictors of in-hospital UGIB in patients with STEMI were age, hemoglobin, hematocrit, and mean hemoglobin concentration.
RESUMEN
Objective:To study the structural damage of cerebral white matter in patients with chronic migraine (CM) using magnetic resonance diffusion tensor imaging (DTI), and analyze its correlation with clinical data.Methods:Sixty CM patients, enrolled from Outpatient of Departments of Neurosurgery and Neurology, Affiliated Hospital of Chengdu University of Traditional Chinese Medicine from September 2020 to December 2022, were chosen; and from October 2020 to June 2022, 60 healthy controls matched with age and gender were recruited socially. All subjects accepted whole brain DTI. DTI data were automatically processed by PANDA and FSL softwares, differences of whole brain DTI data between CM patients and healthy controls were compared by atlas-based analysis (ABA) and tract-based spatial statistics (TBSS), and correlations of clinical features with ABA results were analyzed by Pearson correlation in CM patients.Results:In ABA, compared with the healthy control group, the CM group had significantly decreased FA values in the bilateral cerebral peduncles, left inferior cerebellar peduncles, right superior cerebellar peduncles, bilateral medial thalamic tracts, bilateral tapetum (the inner sagittal layer of the corpus callosum), bilateral hook bundles, and right posterior limb of the internal capsule ( P<0.05); compared with the healthy control group, the CM group had significantly increased mean diffusivity (MD) in the right cingulate gyrus and posterior part of the internal lenticular nucleus, statistically decreased axial diffusivity (AD) in the bilateral cerebral peduncles, bilateral medial thalamic tracts, and right cingulate gyrus ( P<0.05); compared with the healthy control group, the CM group had significantly increased radial diffusivity (RD) in the left tapetum, left inferior cerebellar peduncles, and cerebral peduncles ( P<0.05). In TBSS, no differences in FA, MD, RD and AD in the white matter fiber skeleton were noted between the 2 groups ( P>0.05). In CM patients, visual analogue scale (VAS) scores were negatively correlated with FA in the left subiculum, left medial colliculus and right cerebral peduncle, AD in the right cerebral peduncle, and RD in the left tapetum ( P<0.05); disease duration was negatively correlated with FA in the left subiculum peduncle and positively correlated with RD in the left subiculum peduncle ( P<0.05). Conclusions:Notwithstanding the structural damage of cerebral white matter in CM patients, the white matter fiber skeleton remains unaltered from normal subjects, without pathological damage of the fiber skeleton. Structural changes in the brainstem, cerebellum and corpus callosum are associated with VAS scores and disease duration, and may be important factors for CM pathogenesis.
RESUMEN
Objective:To explore the effect of minimally invasive hematoma puncture and drainage in the treatment of elderly patients with cerebral hemorrhage by using 3D slicer and Sina software to conduct 3D reconstruction and preoperative localization of intracerebral hematoma.Methods:A total of 74 elderly patients with a first-onset intracerebral hematoma aged ≥75 years, having surgical indications and stable vital signs were grouped into 3D slicer plus Sina software localization group(as group A, n=40)or CT localization group(as group B, n=34). Based on the localization, hematoma puncture and drainage were performed after local anesthesia.Preoperative preparation time, hematoma location, puncture success rate, postoperative hematoma clearance rate, postoperative re-bleeding rate and GCS score were statistically analyzed.Glasgow coma scale(GCS)scores were used in predicting the mortality.Results:The preoperative preparation time was significantly shorter in group A than in group B[(5.5±3.4)min vs.(8.5±2.7)min, t=3.337, P=0.001]. The success rate of hematoma puncture and drainage(90.0% and 70.6%, χ2=4.51, P=0.034)and postoperative hematoma clearance rate[(87.5±3.4)% and(80.3±2.7)%, t=10.10, P=0.000]were higher in group A than in group B. There were no significant differences in operative time, the accuracy of hematoma localization, re-bleeding rate and GCS score between the two groups( P>0.05). Conclusions:3D slicer plus Sina software can precisely locate the intracerebral hematoma, and minimally invasive hematoma puncture and drainage of intracerebral hematoma under local anesthesia were safe and effective in the treatment of elderly patients with intracerebral hemorrhage.

RESUMEN
Background@#Enteritis is one of the most frequently reported symptoms in piglets infected with porcine circovirus type 2 (PCV2), but the immunopathogenesis has not been reported. @*Objectives@#This study examined the effect of a PCV2 infection on the intestinal mucosal immune function through morphological observations and immune-related molecular detection. @*Methods@#Morphological changes within the ileum of piglets during a PCV2 infection were observed. The expression of the related-molecules was analyzed using a gene chip. The immunocyte subsets were analyzed by flow cytometry. The secretory immunoglobulin A (SIgA) content was analyzed by enzyme-linked immunosorbent assay. @*Results@#The PCV2 infection caused ileal villus damage, intestinal epithelial cells exfoliation, and an increase in lymphocytes in the lamina propria at 21 days post-infection.Differentially expressed genes occurred in the defense response, inflammatory response, and the complement and coagulation cascade reactions. Most of them were downregulated significantly at the induction site and upregulated at the effector site. The genes associated with SIgA production were downregulated significantly at the induction site. In contrast, the expression of the Toll-like receptor-related genes was upregulated significantly at the effector site. The frequencies of dendritic cells, B cells, and CD8 + T cells were upregulated at the 2 sites. The SIgA content decreased significantly in the ileal mucosa. @*Conclusions@#PCV2 infections can cause damage to the ileum that is associated with changes in immune-related gene expression, immune-related cell subsets, and SIgA production.These findings elucidated the molecular changes in the ileum after a PCV2 infection from the perspective of intestinal mucosal immunity, which provides insights into a further study for PCV2-induced enteritis.
RESUMEN
BACKGROUND: Mesenchymal stem cell transplantation has been proved to be effective for ulcerative colitis, while the effect of endothelial progenitor cells in ulcerative colitis treatment is still unknown. They are both promising cells for tissue engineering, which can be used for cell transplantation. OBJECTIVE: To explore whether co-transplantation of endothelial progenitor cells and adipose mesenchymal stem cells can relieve ulcerative colitis in a mouse model. METHODS: C57BL/6J mice were randomly divided into six groups (n=24 per group): co-transplantation group, mesenchymal stem cell transplantation group, endothelial progenitor cell transplantation group, glucocorticoid treatment group, transplantation control group and normal control group. Murine ulcerative colitis model was established in all groups except for the normal control group. At 7 and 10 days after modeling, transplantation groups were respectively injected via tail vein with adipose mesenchymal stem cells and/or endothelial progenitor cells, glucocorticoid or PBS. Mice were sacrificed at 12 days after modeling. Colon length, disease activity index, histological score and the serum level of tumor necrosis factor-α were compared between groups. RESULTS AND CONCLUSION: Treatment with glucocorticoid was significantly effective for ulcerative colitis relative to the transplantation control group (P 0.05). Co-transplantation of adipose mesenchymal stem cells and endothelial progenitor cells was better than the other treatments, which significantly improved the shortening of the colon, disease activity index, histological score, and serum level of tumor necrosis factor-α.
RESUMEN
OBJECTIVE@#To explore the effect of mild hypothermia on inflammatory response and angiogenesis in brain tissues of rats with intracerebral hemorrhage (ICH) and its possible mechanism for improving behavioral deficits of the rats After ICH.@*METHODS@#A total of 120 healthy male SD rats were randomly divided into sham operation group, ICH group and mild hypothermia group. Rat models of ICH were established in the latter two groups by stereotactic injection of autogenous blood in the brain, and the rats in the sham operation group received injection of normal saline in the same manner. At 15 min after modeling, the rats in hypothermia group were subjected to mild hypothermia (30-32 ℃) for 8 h followed by rewarming (37-38 ℃); the body temperature was maintained at 37-38 ℃ in the other two groups. At 2, 4, 7, 14 and 21 days after the treatment, Longa scoring, balance beam scoring and Berderson scoring were used to evaluate the behavioral deficits of the rats. Immunohistochemical staining was used to detect the protein expressions of tumor necrosis factor-α (TNF-α) and nuclear factor-κB (NF-κB) in the brain tissue of the rats, and the mRNA expressions of α subunit of hypoxia-inducible factor 1 (HIF1-α) and vascular endothelial growth factor (VEGF) were detected using RT- PCR.@*RESULTS@#At 2, 4, 7, 14 and 21 days after the treatment, the behavioral scores of the rats were significantly higher in ICH group and mild induced hypothermia group than in the sham operation group ( < 0.05 or 0.01). The protein expressions of TNF-α and NF-κB and mRNA expressions of HIF1-α and VEGF were significantly higher in ICH group and mild hypothermia group than in the sham operation group ( < 0.01). The behavioral scores were significantly lower in mild hypothermia group than in ICH group ( < 0.05), and the protein expressions of TNF-α and NF-κB were lower and the mRNA expressions of HIF1- α and VEGF were higher in mild hypothermia group than in ICH group ( < 0.05 or 0.01).@*CONCLUSIONS@#Mild hypothermia can improve behavioral deficits in rats with ICH possibly by antagonizing brain inflammation and promoting angiogenesis.
RESUMEN
OBJECTIVE: To establish the method for the content determination of gentiopicrin and loganic acid in Gentiana scabra, and to investigate the correlation of their contents with appearance traits and quality gradation criterion. METHODS: HPLC method was adopted. The determination was performed on Ascentis Express C18 column with mobile phase consisted of 0.1% phosphoric acid-acetonitrile (gradient elution) at the flow rate of 0.4 mL/min. The column temperature was 30 ℃, and detection wavelength was set at 240 nm. The sample size was 1 μL. Taking the length, number and diameter of fibrous roots as indexes, the appearance and morphological characteristics of G. scabra were studied. The relationship of gentiopicrin and loganic acid content with the appearance property of medicinal material was analyzed by SPSS 21.0 software. k-mean clustering analysis was carried out by using SPSS 21.0 software, and gradation standard for G. scabra was established preliminarily. RESULTS: The linear range of gentiopicrin and loganic acid were 0.5-3.0 μg/mL (r=0.999 9) and 0.05-0.50 μg/mL (r=0.999 9). The limit of quantification of gentiopicrin and loganic acid were 0.295, 0.289 μg/mL; the detection limit were 0.082, 0.081 μg/mL; RSDs of precision, stability, repeatability tests were all lower than 2%; the recovery rates were 97.56%- 102.23% (RSD=1.56%, n=6) and 97.58%-102.67% (RSD=1.86%, n=6). Correlation results showed that there was a significant positive correlation of the length of G. scabra, the number of roots, root diameter, with the contents of gentiopicrin and loganic acid. The order of affecting content was the number of roots >length >root diameter. k-means clustering analysis showed that 54 batches of G. scabra was divided into two categories; S4-S6,S13,S17-S23,S25,S28,S31-S34 were clustered into a category; S1-S3, S7-S12, S14-S16, S24, S26,S27,S29, S30,S35-S54 were clustered into the other category. The results of gradation showed that 54 batches of G. scabra could be divided into two grades, and the results were consistent with the cluster analysis. CONCLUSIONS: Established method is simple and stable, and can be used for simultaneous determination of gentiopicrin and loganic acid in G. scabra. The more fibrous roots, the longer the length, the thicker the root, the higher the content of gentiopicroside and loganic acid, the better the quality of G. scabra.
RESUMEN
Objectives To conduct grading comparison for the damage degree of pyramidal tracts after procedure in patients with unilateral hypertensive putamen hemorrhage via transsylvian-transinsular (TS-TI) approach and transcortical transtemporal (TC-TF) approach using magnetic resonance diffusion tensor imaging (DTI) and to evaluate the postoperative recovery of the patients according to the quality criteria of the activities of daily living (ADL),and to identify the advantages and disadvantages of both surgical approaches.Methods Sixty-three consecutive patients with first onset of unilateral hypertensive basal ganglia putamen hemorrhage admitted to Department of Neumlsurgery in Affiliated Hospital of Southwest Medical University of Traditional Chinese Medicine were enrolled prospectively.The volume of hematoma at admission was 26-45 ml.They were randomly divided into group A and group B by random number table.The patients in group A (n =31) were treated via the TS-TI approach,and those of group B (n =32) were treated via the TC-TT approach.The operator was the same surgeon.The patients of rebleeding were excluded (4 in group A,7 in group B),and 52 patients were actually included,including 27 in group A and 25 in group B.The DTI examinations were perforrned 5 to 8 d after procedure.The image data were processed by PHILIPS Extended MR Workspace 2.6.3.4 (EMW 2.6.3.4) software.The bilateral pyramidal tracts were reconstructed,the damage degree of pyramidal tract and its relationship with hematoma and surgical approach were observe respectively.The ADL quality criteria were used to evaluate the recovery at 3 months after procedure.The SPSS 17.0 software was used to conduct rank sum test for the pyramidal tract injury grade after procedure in both groups.The number of rebleeding in the operation areas and the ADL quality criteria evaluation were tested by Chi-squared test.Results There was no significant difference in the postoperative rebleeding rate between group A (12.9%,4/31) and group B (21.9%,7/32) (x2 =0.367,P =0.545).The postoperative pyramidal tract damage degree of group A was better than that of group B.There was significant difference (U =180.00,P =0.004).The comparison of ADL quality evaluation in both groups after procedure showed that the good prognosis rate (81.5%,22/27) of group A after procedure was better than that of group B (56.0%,14/25).There was significant difference (x2 =3.957,P =0.047).Conclusions The three-dimensional relationship between the hematoma lesions and the pyramidal tracts was observed by DTI,the damage degree of the pyramidal tracts were identified.The TS-TI approach was superior to the TC-TF approach in the postoperative damage degree of pyramidal tract and the quality of ADL for the treatment of hypertensive putamen hemorrhage.
RESUMEN
Objective We attempted to investigate optic radiation (OR) injury and visual field mean defect (MD) in patients with hypertensive putaminal hemorrhage by using diffusion tensor imaging (DTI). Methods Thirty-three first onset of patients with hypertensive putaminal hemorrhage and 30 normal healthy control subjects were recruited. DTI data were acquired between 3 and 5 days as well as 3 months after onset. DTI-Studio software was used to reconstruct the OR and examine the degree of OR injury (typeⅠ, Ⅱ, and type Ⅲ). Fractional anisotropies (FA) and apparent diffusion coefficient (ADC)values of the ORs were measured. Statistical analysis was performed to calculate hematoma volume, MD,OR-FA and ADC values by using SPSS 17.0 software. Results FA and ADC values of ORs were not significantly different between the two hemispheres in normal control groups (student t-test, P>0.05). Compared with MD values in control group, the visual field was significantly impaired in patients group (P<0.01). FA and ADC values of ORs were significantly different between two hemispheres in patient group (student t-test, P<0.01). There was no correlation of hematoma volume with OR-FA nor with ADC values nor with MD values (P>0.05). The MD values were correlated with OR-FA and ADC values after onset(P<0.05). MD, FA and ADC values of ORs in the affected hemisphere of the patient group were significantly different for the three OR types between 3 and 5 days as well as 3 months after onset (P<0.01). Conclusion DTI can examine the three-dimensional relationship between hematoma and OR, reflect the changes of OR morphology and predict the degree of visual-field defects.

RESUMEN
BACKGROUND:Adipose-derived mesenchymal stem cels have gained more and more attention due to their high safety, less invasiveness, easy purification and rapid proliferation. OBJECTIVE:To isolate and culture adipose-derived mesenchymal stem cels efficiently and rapidly with high purity and then to explore the cel homing to the intestinal tract after fluorescence labeling. METHODS: Mouse adipose tissue obtained from the groin and epididymis was asepticaly isolated and digested with 0.1% colagenase I. Then the digested cels and undigested adipose tissue were cultured together in the dish to harvest adipose-derived mesenchymal stem cels. The cels were identified by morphology, surface markers, growth kinetics, osteogenic and adipogenic differentiation potential, and then labeled by PKH67 before injected into ulcerative colitis mouse models through the tail vein to observe their homing to the intestinal tract. RESULTS AND CONCLUSION:In vitro, adipose-derived mesenchymal stem cels isolated by this method exhibited spindle-like appearance, grew intensively and arranged in a swirling shape. Adipose-derived mesenchymal stem cels expressed CD29, CD44 and CD90, but not expressed CD45. After osteogenic induction, alkaline phosphatase staining showed black particles and alizarin red S staining showed red mineralized nodules. After adipogenic induction, oil red O staining showed many lipid droplets were dyed red. Cel growth curve showed cels at 3-5 days were in logarithmic growth phase and they were active. Under fluorescence microscopy, frozen sections of the colon were found green fluorescence points that were increased with time. Results suggest that adipose-derived mesenchymal stem cels isolated and culturedin vitro can proliferate rapidly, purify easily and can be induced to osteoblasts and adipocytes; in vivo, PKH67-labeled cels can home to and proliferate in the colon.
RESUMEN
OBJECTIVE: To determine the differences between tracheal foreign body aspiration and bronchial foreign body aspiration. METHODS: This retrospective study includes 1007 patients with the diagnosis of foreign body aspiration according to rigid bronchoscopy. Patients were divided into two groups: tracheal and bronchial foreign body groups. Age, sex, clinical presentation, pre-operative radiographic findings, rigid bronchoscopy findings, types of foreign body, and the complications of each group were observed and analyzed. RESULTS: Out of 989 study patients, there were 146 patients (14.5%) in the tracheal foreign body group and 843 patients (83.7%) in the bronchial foreign body group. Eighteen patients with FBs located in the larynx and presenting with multiple FBs located in the tracheal and bronchial regions were excluded from this study. The majority of the patients were under the age of three for both groups. The male to female ratio was significantly higher in the bronchial foreign body group (P<0.001). More patients in the bronchial foreign body group were misdiagnosed upon first clinical visit (P=0.001), referred from another hospital (P<0.05), or had delayed diagnosis (P<0.05). The most prominent symptom in both groups was cough, followed by decreased breath sounds, wheezing, and dyspnea. More patients in the bronchial foreign body group experienced decreased breath sounds (P<0.001), while more patients in the tracheal foreign body group experienced dyspnea (P<0.05). Chest fluoroscopy abnormalities were observed at a higher frequency in the bronchial foreign body group (P<0.001). Lateral neck X-ray results showed higher frequencies of abnormalities in the tracheal foreign body patients. Out of 30 patients in the tracheal foreign body group received a CT scan, 27 had abnormal scan results, while all 253 patients in the bronchial foreign body subgroup had abnormal results. The majority of foreign bodies were organic materials and were removed by rigid bronchoscopy at the first clinical session in 96.6% of tracheal foreign body cases and 96.0% of bronchial foreign body cases (P=0.727). Major complications, including one death, were observed only in the bronchial foreign body group. CONCLUSIONS: The nature of tracheal foreign body aspiration is different from bronchial aspiration. Clinical presentation and pre-operative radiographic findings are helpful for diagnosis. The clinician should understand the differences between tracheal and bronchial FB cases and provide the appropriate management when either is presented.

Objective To investigate the association between morning blood pressure surge(MBPS)and the ambulatory blood pressure monitoring parameters on carotid artery intima-media thickness(IMT)in hypertensive patients.Methods Based on the occurrence of MBPS two hundred twenty six hypertensive patients were allocated as MBPS(n=51)or non-MBPS(n=175).However,based on the IMT,226 patients were stratified as IMT increased(n=94)or group normal IMT(n=132).Plasma lipids,24 h ambulatory blood pressure monitoring(ABPM)and ultrasound examinations of the IMT of carotid arteries were determined.Results 1)The value of MBPS,mean arterial pressure(MAP),morning pulse pressure(MPP),carotid artery IMT,carotid artery crouse score in MBPS group were significantly higher than that in no MBPS groups(P
