RESUMO

Objective To analyze the burden of disease attributable to coronary heart disease in adult patients in 2020, to compare the disease burden of patients with coronary heart disease among different sociodemographic indexes (SDI) , and to explore the correlation between the two to provide theoretical guidance for coronary heart disease prevention. Methods The data of 881 adult patients with coronary heart disease in our Hospital in 2020 were collected, and the data, such as illness, morbidity, mortality and disability-adjusted life years (DALY) of adult patients with coronary heart disease were analyzed. Pearson correlation was used to analyze the association between disease burden and sociodemographic index in adult patients with coronary heart disease. Results The prevalence and incidence of adult patients with coronary heart disease were higher in women than in men, while the mortality rate and DALY rate were mainly higher in men than in women. The prevalence, morbidity and mortality rates increased in different age groups, and increased rapidly in the age group of 45 years and beyond. The prevalence of DALY in adult patients with coronary heart disease in different age groups also showed an upward trend, and increased rapidly in the age group of 35 years and beyond. The SDI value of adult patients with coronary heart disease was (0.52±0.16), of which the low SDI value was (0.13±0.05), the medium and low SDI value was (0.34±0.17), the medium SDI value was (0.50±0.14), the medium and high SDI value was (0.82±0.25), and the high SDI value was (0.93±0.13). The chi-square results showed that there were differences in mortality (χ2=12.358, P=0.020) and DALY rate (χ2 =14.557, P=0.011) of adult patients with coronary heart disease between different grades of SDI groups, and the differences were statistically significant. Pearson-related results showed that SDI and DALY rate were negatively correlated in adult patients with coronary heart disease (r=-0.374, P=0.022), and there were gender differences. SDI was negatively correlated with DALY rate in male patients with coronary heart disease (r=-0.489, P=0.017), and SDI was negatively correlated with mortality (r=-0.290, P=0.040) and DALY rate in female patients with coronary heart disease (r=-0.392, P=0.006). Conclusion Burden of disease attributed to coronary heart disease in adult patients varies by sex and it has a negative correlation with SDI, and the improvement of national welfare and education level, that is, the increase of SDI may have a certain effect on reducing the burden of coronary heart disease.

RESUMO

ObjectiveTo investigate the effect of galvanic vestibular stimulation on stroke patients with lateropulsion. MethodsFrom February to October, 2023, 30 stroke patients with lateropulsion in the First Affiliated Hospital of Nanjing Medical University were divided into control group (n = 15) and experimental group (n = 15) randomly. The control group received routine rehabilitation and sham galvanic vestibular stimulation, and the experimental group received routine rehabilitation and true galvanic vestibular stimulation, for two weeks. They were assessed with Scale for Contraversive Pushing (SCP), subjective visual vertical (SVV), Line Cancellation Test (LCT), Star Cancellation Test (SCT), Berg Balance Scale (BBS), Holden Functional Ambulation Category (FAC) and Barthel Index (BI) before and after treatment. ResultsAll the indexes improved in both groups after intervention (|t| > 2.461, Z > 3.000, P < 0.05), except the SVV orientation, SVV certainty and SCT in the control group; while the SCP, SVV certainty, LCT and FAC were better in the experimental group than in the control group (|t| > 2.189, Z = -2.862, P < 0.05), and the differences before and after intervention were better in the experimental group than in the control group (|t| > 2.382, P < 0.05), except LCT. SCP was correlated with SVV orientation, SVV certainty, SCT, BBS, BI and FAC (|r| > 0.381, P < 0.05). ConclusionGalvanic vestibular stimulation can improve the lateropulsion, balance, walking function and activities of daily living in stroke patients, which may be related to improvement for spatial cognitive function, especially vertical perception.

RESUMO

ObjectiveTo investigate the effect of modified Baduanjin exercise, as an rehabilitation exercise, on cardiopulmonary function, motor function and activities of daily living in patients with stroke. MethodsFrom January to September, 2023, 42 stroke patients in the Nanjing Qixia District Hospital were randomly divided into control group (n = 21) and experimental group (n = 21). The control group received routine rehabilitation, and the experimental group received modified Baduanjin exercise in addition, for four weeks. They were assessed with peak oxygen uptake (VO2peak), anaerobic threshold (AT), peak oxygen pulse (VO2peak/HR), forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), peak expiratory flow (PEF), Fugl-Meyer Assessment-upper extremities (FMA-UE), Berg Balance Scale (BBS) and modified Barthel Index (MBI) before and after intervention. ResultsVO2peak, AT, and the scores of FMA-UE, BBS and MBI improved in the control group after intervention (|t| > 2.256, |Z| > 2.936, P < 0.05); while VO2peak, AT, VO2peak/HR, FVC, FEV1, PEF, and the scores of FMA-UE, BBS and MBI improved in the experimental group (|t| > 4.390, |Z| > 3.451, P < 0.001); and all the indexes were better in the experimental group than in the control group (|t| > 4.136,|Z| > 2.751,P < 0.01), except the scores of BBS and MBI. ConclusionModified Baduanjin exercise can improve the cardiopulmonary function and upper limb motor function for stroke patients.

RESUMO

ObjectiveTo explore the impact of subjective vertical perception impairment after stroke on visuospatial cognition, balance, walking and activities of daily living, to investigate the mediating role of visuospatial cognition and lateropulsion. MethodsFrom February to December, 2023, 96 stroke patients were selected from the Rehabilitation Medicine Center of the First Affiliated Hospital of Nanjing Medical University. They were divided into vertical perception impairment group (n = 53) and non-vertical perception impairment group (n = 43). They were assessed with National Institutes of Health Stroke Scale (NIHSS), the Scale for Contraversive Pushing (SCP), Burke Lateropulsion Scale (BLS), Line Bisection Test (LBT), Line Cancellation Test (LCT), Star Cancellation Test (SCT), Subjective Visual Vertical (SVV), Berg Balance Scale (BBS), Holden Functional Ambulation Categories (FAC) and Barthel Index (BI). ResultsScores of SVV orientation, SVV uncertainty, NIHSS, SCT, SCP, BLS, BBS, FAC and BI were worse in the vertical perception impairment group than in the non-vertical perception impairment group (|t| > 2.414, Z = -3.481, P < 0.05). Scores of SVV were correlated with SCT, BLS and BBS (|r| ≥ 0.273, P < 0.05). After controlling for age and gender, SVV orientation score did not directly impact BBS score (β = -0.011, P = 0.920). However, it exerted a partial mediating effect through BLS (effect = -0.173, 95%CI -0.278 to -0.076) and a chain-mediated effect through SCT and BLS (effect = -0.073, 95%CI -0.137 to -0.027), impacting BBS score. ConclusionSubjective vertical perception impairment results in poorer visuospatial cognition, balance, walking and activities of daily living in stroke patients. This influence on balance function is mediated through the mediating effects of visuospatial cognition and lateropulsion.

RESUMO

OBJECTIVE@#To investigate the safety and the short-term efficacy of venetoclax combined with azacitidine followed by cladribine (VAC regimen) in children with refractory/ relapsed acute myeloid leukemia (AML).@*METHODS@#The clinical data, treatment outcomes, complications, and blood product consumption of 6 children with refractory/relapsed AML treated with VAC regimen in the Children's Hospital of Soochow University from August 2021 to December 2021 were retrospectively analyzed.@*RESULTS@#Among the 6 children, there were 1 male and 5 females. 5 cases were refractory AML, and 1 case was relapsed AML, which recurred again 16 months after allogeneic hematopoietic stem cell transplantation. 4 children were accompanied by chromosomes or genes that predicted poor prognosis, such as RUNX1, FLT3-ITD, KMT2A exon 2-exon 8 dup, MLL-AF6, 7q-, KMT2A exon 2-exon 10 dup, etc. After received VAC regimen, 4 cases achieved CR+CRi, 1 case achieved PR (only MRD did not relieve, MRD was 0.59%), and 1 case was NR (but the proportion of bone marrow blasts decreased). All 6 patients had grade Ⅳ neutropenia, and 4 patients had grade Ⅳ thrombocytopenia. During the period of neutropenia, none of the 6 children developed symptoms of infection such as fever, cough, and diarrhea. No treatment-related death occurred.@*CONCLUSION@#Venetoclax combined with azacitidine followed by cladribine provides a new treatment option for patients with relapsed/refractory AML who have poor efficacy in early induction remission theragy, showing good efficacy and safety.

RESUMO

OBJECTIVE@#To investigate the correlation between plasmacytoid dendritic cell (pDC) dose in grafts and the occurrence of cytomegalovirus (CMV) infection after allogeneic hematopoietic stem cell transplantation (allo-HSCT).@*METHODS@#The clinical data of 80 children who received allo-HSCT in Children's Hospital of Soochow University from August 20, 2020 to June 11, 2021 were retrospectively analyzed. Proportions of DC subsets and T-cell subsets in grafts were detected by flow cytometry in order to calculate infused cell dose of each cell. Weekly monitoring of CMV-DNA copies in peripheral blood for each child were performed after transplantation. The last follow-up date was December 31, 2021.@*RESULTS@#All the children gained hematopoietic reconstitution. CMV infection was observed in 51 children (63.8%±5.4%) within the first 100 days after transplantation, including 2 cases developing CMV disease. Univariate analysis indicated that infused doses of DC and pDC were significantly associated with CMV infection within 100 days after allo-HSCT (P <0.05). Multivariate analysis indicated that a high dose infusion of pDC was an independent protective factor for CMV infection within 100 days after allo-HSCT (P <0.05). By the end of follow-up, 7 children died of transplantation-related complications, including 2 deaths from CMV disease, 2 deaths from extensive chronic graft-versus-host disease, and 3 deaths from capillary leak syndrome. The overall survival rate was 91.2%.@*CONCLUSION@#The pDC in grafts may be associated with early infection of CMV after allo-HSCT, while a high infused pDC dose may serve as a protective factor for CMV infection after transplantation.

RESUMO

OBJECTIVE@#To explore prevalence, risk factors and treatment of ankle sprain of young college student , in order to obtain accurate epidemiological data.@*METHODS@#From March 2019 to May 2019, 552 college students(1 104 sides of anke joints) from Xi'an Physical Education university were enrolled in study according to inclusion and excludion standard, including 309 males and 243 females aged from 16 to 24 years old with an average of (20.9±3.7) years old. Age, gender, and body mass indes(BMI) etc were recorded. Morbidity of acute and chronic ankle sprains of physical students, treatment after the first sprain (cold compress, cast or plaster bracing and medicine), visual analogue scale (VAS) during walking were assessed through ankle sprain questionnaire;Cumberland ankle instability tool (CAIT), Maryland foot score were applied to assess ankle function. Lateral ankle ligament injury was objectively assessed by musculoskeletal ultrasonography.@*RESULTS@#The prevalence of acute ankle sprain(AAS) was 96.20% (531/552), and the incidence of AAS was 59.96% (622/1 104). The prevalence of chronic ankle joint instability(CAI) was 16.85% (93/552), and the incidence of CAI was 8.97% (99/1 104). In the four categories of sports, college student suffered from multiple sprains in performance majors group was 22.20% (14/63), including of aerobicsand dance performance. The incidence of AAS of ball sports was 8.60%(14/163). After the first sprain, most college students(94.4%) were received cold compression, about 60% of them went to hospital;however, only 44.7% students were received standard treatmens(cast or plaster), only 35.3% of them were received hard ankle orthosis. In 552 college students, 44 students were suffered from more than 4 times of ankle sprain, and the total incidence was 7.97% (44/552). Cumberland score was 26.6±2.4, Cumberland score of students sprained ankle joint more than 4 times was (29.2±1.1), suggested it was a risk factor for ankle joint instability. VAS of students sprained ankle joint more than 4 times was higher than that of less than 4 times(P<0.05), Maryland foot score was significantly lower than that of that of <4 times(P<0.05). Musculoskeletal ultrasonography measured the thickness of anterior tibiofibular ligament(ATFL) was (2.41±0.41) mm, and the thickness of calcaneofibular ligament(CFL) was (1.92±0.21) mm, and had no statistical difference(P>0.05).@*CONCLUSION@#Ninty-four percent college students had at least once ankle sprain, ankle sprains were more common in erobics and ball sports. After the first sprain, the proportion of cast or plaster treatment was less than 50%. Sprained ankle joint more than 4 times is a risk factor, and musculoskeletal ultrasonography showed thickening of both ATFL and CFL, while no statstical difference.

RESUMO

Pentaxin 3 (PTX3), as a multifunctional glycoprotein, plays an important role in regulating inflammatory response, promoting tissue repair, inducing ectopic calcification and maintaining bone homeostasis. The effect of PTX3 on bone mineral density (BMD) may be affected by many factors. In PTX3 knockout mice and osteoporosis (OP) patients, the deletion of PTX3 will lead to decrease of BMD. In Korean community "Dong-gu study", it was found that plasma PTX3 was negatively correlated with BMD of femoral neck in male elderly patients. In terms of bone related cells, PTX3 plays an important role in maintaining the phenotype and function of osteoblasts (OB) in OP state;for osteoclast (OC), PTX3 in inflammatory state could stimulate nuclear factor κ receptor activator of nuclear factor-κB ligand (RANKL) production and its combination with TNF-stimulated gene 6(TSG-6) could improve activity of osteoclasts and promote bone resorption;for mesenchymal stem cells (MSCs), PTX3 could promote osteogenic differentiation of MSCs through PI3K/Akt signaling pathway. In recent years, the role of PTX3 as a new bone metabolism regulator in OP and fracture healing has been gradually concerned by scholars. In OP patients, PTX3 regulates bone mass mainly by promoting bone regeneration. In the process of fracture healing, PTX3 promotes fracture healing by coordinating bone regeneration and bone resorption to maintain bone homeostasis. In view of the above biological characteristics, PTX3 is expected to become a new target for the diagnosis and treatment of OP and other age-related bone diseases and fracture healing.

RESUMO

OBJECTIVE@#To compare clinical efficacy of platelet-rich plasma (PRP) and extracorporeal shock wave in treating chronic insertional Achilles tendinopathy.@*METHODS@#From February 2019 to August 2021, 42 patients with chronic insertional Achilles tendinopathy were selected and divided into PRP group(20 patients, 28 feet) and shock wave group (22 patients, 29 feet). In PRP group, there were 12 males and 8 females, aged 47.00(28.00, 50.75) years old, and the courses of disease ranged 7.00(6.00, 7.00) months;PRP injection was performed in the Achilles tendon stop area of the affected side. In shock wave group, there were 16 males and 6 females, aged 42.00(35.75, 47.25) years old;and the courses of disease was 7.00(6.00, 8.00) months;shock wave was performed in Achilles tendon stop area of the affected side and triceps surae area. Visual analogue scale (VAS) and Victorian Institute of Sport Assessment-Achilles (VISA-A) were applied to evaluate clnical effect before treatment, 1, 3 and 6 months after treatment, and satisfaction of patients was investigated.@*RESULTS@#VAS and VISA-A score in both groups were significantly improved at 1, 3 and 6 months after treatment than before treatment (P<0.05), VAS and VISA-A score in PRP group at 6 months after treatment were significantly higher than those at 1 and 3 months after treatment, and VAS and VISA-A score in shock wave group were lower than those at 1 and 3 months after treatment (P<0.05). There was no significant difference in VAS and VISA-A score between two groups before treatment, 1 and 3 months after treatment(P>0.05), while VAS and VISA-A score in PRP group were better than those in shock wave group at 6 months after treatment(P<0.05), and the satisfaction survey in PRP group was better than that in shock wave group(P<0.05).@*CONCLUSION@#PRP injection has a good clinical effect on chronic insertional Achilles tendinopathy with high patient satisfaction, and medium-and long-term effect of PRP injection for the treatment of chronic insertional Achilles tendinopathy is better than that of extracorporeal divergent shock wave.

RESUMO

The aim of this study is to explore the mechanism of ligustilide, the main active constituent of essential oils of traditional Chinese medicine Angelicae Sinensis Radix, on alleviating oxygen-glucose deprivation/reperfusion(OGD/R) injury in PC12 cells from the perspective of ferroptosis. OGD/R was induced in vitro, and 12 h after ligustilide addition during reperfusion, cell viability was detected by cell counting kit-8(CCK-8) assay. DCFH-DA staining was used to detect the level of intracellular reactive oxygen species(ROS). Western blot was employed to detect the expression of ferroptosis-related proteins, glutathione peroxidase 4(GPX4), transferrin receptor 1(TFR1), and solute carrier family 7 member 11(SLC7A11), and ferritinophagy-related proteins, nuclear receptor coactivator 4(NCOA4), ferritin heavy chain 1(FTH1), and microtubule-associated protein 1 light chain 3(LC3). The fluorescence intensity of LC3 protein was analyzed by immunofluorescence staining. The content of glutathione(GSH), malondialdehyde(MDA), and Fe was detected by chemiluminescent immunoassay. The effect of ligustilide on ferroptosis was observed by overexpression of NCOA4 gene. The results showed that ligustilide increased the viability of PC12 cells damaged by OGD/R, inhibited the release of ROS, reduced the content of Fe and MDA and the expression of TFR1, NCOA4, and LC3, and improved the content of GSH and the expression of GPX4, SLC7A11, and FTH1 compared with OGD/R group. After overexpression of the key protein NCOA4 in ferritinophagy, the inhibitory effect of ligustilide on ferroptosis was partially reversed, indicating that ligustilide may alleviate OGD/R injury of PC12 cells by blocking ferritinophagy and then inhibiting ferroptosis. The mechanism by which ligustilide reduced OGD/R injury in PC12 cells is that it suppressed the ferroptosis involved in ferritinophagy.

RESUMO

Ulcerative colitis(UC) is a recurrent, intractable inflammatory bowel disease. Coptidis Rhizoma and Bovis Calculus, serving as heat-clearing and toxin-removing drugs, have long been used in the treatment of UC. Berberine(BBR) and ursodeoxycholic acid(UDCA), the main active components of Coptidis Rhizoma and Bovis Calculus, respectively, were employed to obtain UDCA-BBR supramolecular nanoparticles by stimulated co-decocting process for enhancing the therapeutic effect on UC. As revealed by the characterization of supramolecular nanoparticles by field emission scanning electron microscopy(FE-SEM) and dynamic light scattering(DLS), the supramolecular nanoparticles were tetrahedral nanoparticles with an average particle size of 180 nm. The molecular structure was described by ultraviolet spectroscopy, fluorescence spectroscopy, infrared spectroscopy, high-resolution mass spectrometry, and hydrogen-nuclear magnetic resonance(H-NMR) spectroscopy. The results showed that the formation of the supramolecular nano-particle was attributed to the mutual electrostatic attraction and hydrophobic interaction between BBR and UDCA. Additionally, supramolecular nanoparticles were also characterized by sustained release and pH sensitivity. The acute UC model was induced by dextran sulfate sodium(DSS) in mice. It was found that supramolecular nanoparticles could effectively improve body mass reduction and colon shortening in mice with UC(P<0.001) and decrease disease activity index(DAI)(P<0.01). There were statistically significant differences between the supramolecular nanoparticles group and the mechanical mixture group(P<0.001, P<0.05). Enzyme-linked immunosorbent assay(ELISA) was used to detect the serum levels of tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6), and the results showed that supramolecular nanoparticles could reduce serum TNF-α and IL-6 levels(P<0.001) and exhibited an obvious difference with the mechanical mixture group(P<0.01, P<0.05). Flow cytometry indicated that supramolecular nanoparticles could reduce the recruitment of neutrophils in the lamina propria of the colon(P<0.05), which was significantly different from the mechanical mixture group(P<0.05). These findings suggested that as compared with the mechanical mixture, the supramolecular nanoparticles could effectively improve the symptoms of acute UC in mice. The study provides a new research idea for the poor absorption of small molecules and the unsatisfactory therapeutic effect of traditional Chinese medicine and lays a foundation for the research on the nano-drug delivery system of traditional Chinese medicine.

RESUMO

Objective To investigate the clinicopathological features,immunohistochemical features,diagnosis,and relationship with sporadic prostate cancer in primary small cell neuroendocrine carcinoma of the bladder. Methods We retrospectively analyzed the clinical characteristics of 12 patients with primary small cell neuroendocrine carcinoma of the bladder diagnosed at Beijing Chao-Yang Hospital affiliated to Capital Medical University from January 2013 to September 2022.The histological features of primary small cell neuroendocrine carcinoma of the bladder were re-evaluated by two pathologists according to the 2022 revision of the World Health Organization Classification of Tumors of the Urinary System and Male Genital Organs.Electronic medical records were retrieved,and telephone follow-up was conducted from the time of histopathological diagnosis to the death or the end of the last follow-up until January 31,2023. Results The 12 patients include 7 patients in pT3 stage and 1 patient in pT4 stage.Eight patients were complicated with other types of tumors,such as high-grade urothelial carcinoma of the bladder and squamous cell carcinoma.Five patients had sporadic prostate cancer.Immunohistochemical staining showed that 12 (100.0%),10 (83.3%),and 8 (66.7%) patients were tested positive for CD56,Syn,and CgA,respectively.The Ki67 proliferation index ranged from 80% to 90%.Five patients with urothelial carcinoma were tested positive for CK20,GATA3,and CK7.P504S was positive in all the 5 patients with prostate cancer,while P63 and 34βE12 were negative.The follow-up of the 12 patients lasted for 3-60 months.Eight of these patients died during follow-up,with the median survival of 15.5 months.Four patients survived. Conclusions Primary small cell neuroendocrine carcinoma of the bladder is a rare urological tumor with high aggressiveness and poor prognosis.In male patients with bladder prostatectomy,all prostate tissue should be sampled.If prostate cancer is detected,the prostate-specific antigen level should be monitored.

RESUMO

Alcoholic liver disease(ALD), with its increasing morbidity and mortality, has seriously and extensively affected the health of people worldwide. Methyl ferulic acid(MFA) has been proven to significantly inhibit alcohol-induced lipid production in L02 cells through the AMP-activated protein kinase(AMPK) pathway, but its in-depth mechanism remains unclear. This study aimed to further clarify the mechanism of MFA in improving lipid accumulation in L02 cells through the microRNA-378b(miR-378b)-mediated calcium/calmodulin-dependent protein kinase kinase 2(CaMKK2)-AMPK signaling pathway based on existing researches. L02 cells were induced by 100 mmol·L~(-1) ethanol for 48 h to establish the model of ALD in vitro, and 100, 50, and 25 μmol·L~(-1) concentration of MFA was treated. MiR-378b plasmids(containing the overexpression plasmid-miR-378b mimics, silence plasmid-miR-378b inhibitor, and their respective negative control-miR-378b NCs) were transfected into L02 cells by electroporation to up-regulate or down-regulate the levels of miR-378b in L02 cells. The levels of total cholesterol(TC) and triglyceride(TG) in cells were detected by commercial diagnostic kits and automatic biochemical analyzers. The expression levels of miR-378b in L02 cells were detected by real-time quantitative polymerase chain reaction(qRT-PCR). CaMKK2 mRNA levels were detected by PCR, and protein expressions of related factors involved in lipid synthesis, decomposition, and transport in lipid metabolism were detected by Western blot. The results displayed that ethanol significantly increased TG and TC levels in L02 cells, while MFA decreased TG and TC levels. Ethanol up-regulated the miR-378b level, while MFA effectively inhibited the miR-378b level. The overexpression of miR-378b led to lipid accumulation in ethanol-induced L02 cells, while the silence of miR-378b improved the lipid deposition induced by ethanol. MFA activated the CaMKK2-AMPK signaling pathway by lowering miR-378b, thus improving lipid synthesis, decomposition, and transport, which improved lipid deposition in L02 cells. This study shows that MFA improves lipid deposition in L02 cells by regulating the CaMKK2-AMPK pathway through miR-378b.

RESUMO

This study explores the effect of total flavonoids of Rhododendra simsii(TFR) on middle cerebral artery occlusion(MCAO)-induced cerebral injury in rats and oxygen-glucose deprivation/reoxygenation(OGD/R) injury in PC12 cells and the underlying mechanism. The MCAO method was used to induce focal ischemic cerebral injury in rats. Male SD rats were randomized into sham group, model group, and TFR group. After MCAO, TFR(60 mg·kg~(-1)) was administered for 3 days. The content of tumor necrosis factor-α(TNF-α), interleukin-1(IL-1), and interleukin-6(IL-6) in serum was detected by enzyme-linked immunosorbent assay(ELISA). The pathological changes of brain tissue and cerebral infarction were observed based on hematoxylin and eosin(HE) staining and 2,3,5-triphenyltetrazolium chloride(TTC) staining. RT-qPCR and Western blot were used to detect the mRNA and protein levels of calcium release-activated calcium channel modulator 1(ORAI1), stromal interaction molecule 1(STIM1), stromal intera-ction molecule 2(STIM2), protein kinase B(PKB), and cysteinyl aspartate specific proteinase 3(caspase-3) in brain tissues. The OGD/R method was employed to induce injury in PC12 cells. Cells were randomized into the normal group, model group, gene silencing group, TFR(30 μg·mL~(-1)) group, and TFR(30 μg·mL~(-1))+gene overexpression plasmid group. Intracellular Ca~(2+) concentration and apoptosis rate of PC12 cells were measured by laser scanning confocal microscopy and flow cytometry. The effect of STIM-ORAI-regulated store-operated calcium entry(SOCE) pathway on TFR was explored based on gene silencing and gene overexpression techniques. The results showed that TFR significantly alleviated the histopathological damage of brains in MCAO rats after 3 days of admini-stration, reduced the contents of TNF-α, IL-1, and IL-6 in the serum, down-regulated the expression of ORAI1, STIM1, STIM2, and caspase-3 genes, and up-regulated the expression of PKB gene in brain tissues of MCAO rats. TFR significantly decreased OGD/R induced Ca~(2+) overload and apoptosis in PC12 cells. However, it induced TFR-like effect by ORAI1, STIM1 and STIM2 genes silencing. However, overexpression of these genes significantly blocked the effect of TFR in reducing Ca~(2+) overload and apoptosis in PC12 cells. In summary, in the early stage of focal cerebral ischemia-reperfusion injury and OGD/R-induced injury in PC12 cells TFR attenuates ischemic brain injury by inhibiting the STIM-ORAI-regulated SOCE pathway and reducing Ca~(2+) overload and inflammatory factor expression, and apoptosis.

RESUMO

Limb length discrepancy(LLD) is a common complication after total hip arthroplasty (THA). Good positioning of the prosthesis and suitable soft tissue tension are essential to ensure hip joint stability. Patients will be more satisfied if almost the same length of both lower extremities is achieved. Preoperative comprehensive evaluation of patients is helpful to prevent the occurrence of LLD after surgery. Therefore, the pelvic spine conditions, as well as type and cause of LLD should be analyzed in detail before surgery. During operation, limb length should be adjusted by touching the position of patella, Kirschner's wires positioning and referring to the relationship between the center of femoral head and the tip of greater trochanter. After surgery, it is necessary to clearly distinguish true LLD from functional LLD, and make a reasonable therapeutic plan according to patient's symptoms and the range of differences in limb length. This article reviews the latest literatures based on clinical practice experience and summarizes the research status of LLD after THA, which helps joint surgeons to have an in-depth understanding of this postoperative complication.

RESUMO

Objective: To evaluate the efficacy of decitabine combined with low dose chemotherapy (LDC) in the treatment of high-risk, refractory and relapsed pediatric acute myeloid leukemia (AML). Methods: Clinical data of 19 AML children treated with decitabine combined with LDC in the Department of Hematology, Children's Hospital of Soochow University from April 2017 to November 2019 were analyzed retrospectively. The therapeutic response, adverse effects and survival status were analyzed,and the outcomes of patients were followed up. Results: Among 19 AML cases, there were 10 males and 9 females. Five cases were high-risk AML, 7 cases were refractory AML, and 7 cases were relapsed AML. After one course of decitabine+LDC treatment, 15 cases achieved complete remission, 3 cases got partial remission, and only 1 case didn't get remission. All patients received allogeneic hematopoietic stem cell transplantation as consolidation therapy. The follow-up time of all cases was 46 (37, 58) months, 14 children had survived. The cumulative three-year overall survival rate was (79±9) %, events free survival rates was (68±11) %, and recurrence free survival rate was (81±10) %. The most common adverse effects related to the induction treatment were cytopenia (19 cases) and infection (16 cases).There were no treatment-related death during the therapy. Conclusion: Decitabine combined with LDC is a safe and effective option for high-risk, refractory and relapsed AML children, which provides an opportunity for HSCT.

RESUMO

Objective:To analyze the clinical characteristics of patients with spontaneous low intracranial pressure (SIH).Methods:The study is a retrospective series. The clinical data of patients with SIH who visited Beijing Hospital from May 2017 to March 2022, including gender, age, symptoms, signs, imaging findings, treatment and outcome, were collected and their clinical characteristics were analyzed.Results:Finally, 8 patients with SIH, 6 females and 2 males, aged (33.5±7.3) years, were included. There were 6 cases of acute onset, 1 case of subacute onset, and 1 case of chronic onset. Four cases had pre-onset triggers, 3 cases were exertional and 1 case was exercise. All 8 cases had orthostatic headache. Three cases were accompanied by neck pain. Six cases were accompanied by autonomic dysfunction, 1 case with blurred vision and neck resistance, and 1 case with tinnitus in both ears. There were no obvious abnormalities in blood routine, liver and kidney function, electrolytes, and coagulation function in 8 cases. The results of the lumbar puncture showed that the cerebrospinal fluid pressure was≤60 mmH 2O(1 mmH 2O=0.009 8 kPa) in 7 cases, and 2 cases were so low that they were undetectable. One patient had normal cerebrospinal fluid pressure (90 mmH 2O). The routine results of cerebrospinal fluid showed 4 cases of an increased number of red blood cells and 2 cases of leukocytosis. The biochemical results of cerebrospinal fluid in all 8 cases were normal. All 8 patients underwent non-contrast MRI scan of the head, and 6 cases found abnormalities, including 2 cases of subdural hematoma, 1 case of subarachnoid hemorrhage, 1 case of brain tissue sinking, and 3 cases of intracranial venous sinus dilation (including 1 case with subdural hematoma). All 8 patients underwent MRI enhancement scan of the head, and 5 patients showed diffuse dural enhancement. Three patients underwent digital subtraction angiography myelogram and computed tomography myelogram, and 2 cases found dural cerebrospinal fluid leakage. One patient underwent magnetic resonance water imaging and no cerebrospinal fluid leakage was found. Eight patients were followed up for 38.5 (10.3, 63.0) months, after conservative treatment, 6 cases of headache relief or disappearance, 1 case relapsed and was admitted 1 week after discharge, non-targeted epidural blood patching (EBP) did not relapse, 1 case underwent non-targeted EBP after conservative treatment failure, headache relief, recurrence after 2 months, thoracic spine 3-4 space targeted EBP, headache disappeared, did not recur. Conclusions:The present study indicate that SIH prevalence in young age is common, the main symptom is orthostatic headache, accommodated with multiple clinical symptoms with various imaging abnormalities. Most patients with SIH can be treated conservatively, if the effect is not good, non-targeted or targeted EBP is feasible.

RESUMO

Objective:To analyze risk factors for unfavorable outcomes after recanalization of large vessel occlusion (LVO) in patients with acute ischemic stroke (AIS).Methods:Patients with AIS-LVO who underwent recanalization treatment (including intravenous thrombolysis and endovascular intervention) at the Stroke Unit of Beijing Hospital from August 2018 to January 2022 were consecutively enrolled. According to the modified Rankin Scale (mRS) at 90-day follow-up after recanalization treatment, participants were classified as unfavorable outcomes (mRS>2) and favorable outcomes (mRS≤2). Baseline clinical data of enrolled patients was collected, and step-wise multivariate logistic regression analysis was used to identify independent risk factors for unfavorable outcomes after recanalization in AIS-LVO patients.Results:A total of 212 AIS-LVO patients were enrolled, including 86 females (41.35%), with an average age of 72.9 years. There were 75 patients in the favorable outcome group and 137 patients in the unfavorable outcome group. Compared with the favorable outcome group, the unfavorable outcome group had a higher average age, a higher proportion of females and patients with atrial fibrillation, higher baseline NIHSS, higher systolic blood pressure, and higher blood creatinine and D-dimer levels (all P<0.05). After adjusting for age and atrial fibrillation as confounding factors, multivariate logistic regression analysis showed that female ( OR=2.859, 95% CI: 1.202-6.799, P=0.018), higher baseline NIHSS ( OR=14.417, 95% CI: 6.269-33.158, P<0.001), higher pre-treatment systolic blood pressure ( OR=1.034, 95% CI: 1.015-1.054, P=0.001), higher emergency blood creatinine level ( OR=1.378, 95% CI: 1.105-1.719, P=0.005), and higher D-dimer level ( OR=3.594, 95% CI: 1.290-10.014, P=0.014) were independent risk factors for unfavorable outcomes after recanalization treatment in patients with AIS-LVO. Conclusion:Female, higher NIHSS, higher systolic blood pressure, higher blood creatinine level and D-dimer level are independent risk factors for unfavorable functional outcomes at 90 days after recanalization treatment of large vessel occlusion in patients with acute ischemic stroke.

RESUMO

One case of knee infection after anterior cruciate ligament reconstruction caused by the gram-positive anaerobic bacterium Finegoldia magna was reported. The patient was admitted to hospital due to fever and knee joint swelling and pain after anterior cruciate ligament reconstruction. Through medical history, physical examination, imaging examination and next-generation sequencing, it was confirmed that the infection was caused by Finegoldia magna. Through literature review, 37 literatures on infectious diseases caused by Finegoldia magna was retrieved and analyzed, and the identification points of anaerobic bacteria, the application of second-generation sequencing technology and the treatment status of infection after anterior cruciate ligament reconstruction were reviewed. The incidence of infection after arthroscopic anterior cruciate ligament reconstruction is low, while anaerobic infection is even more rare and difficult to culture. The next-generation sequencing can be used to assist the diagnosis. On the basis of giving priority to the preservation of the reconstructed ligament, the combined use of arthroscopic debridement, irrigation and sensitive antibiotics is the main treatment method.

RESUMO

Objective:To investigate the value of radiomics based on three-dimensional high resolution MR vessel wall imaging (3D HRMR-VWI) for identifying culprit plaques in symptomatic patients with middle cerebral atherosclerosis.Methods:The clinical and imaging features of 117 patients (139 middle cerebral artery plaques) with cerebrovascular diseases in Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from October 2018 to October 2020 were respectively reviewed. Stratified random sampling was used to divide 139 plaques into training set (97 plaques) and validation set (42 plaque) at the ratio of 7∶3. The plaques were divided into 69 culprit plaques and 70 non-culprit plaques based on plaque MR features and clinical symptoms. The clinical and imaging characteristics of culprit plaques and non-culprit plaques were compared by independent sample t-test, Mann-Whitney U test and χ 2 test, and factors with significant difference between two groups in univariate analysis were further analyzed by multivariate logistic regression to find out the independent predictors of culprit plaques. Radiomics features were extracted, screened and radiomics model was constructed using pre-and post-contrast 3D HRMR-VWI based on the training set. The combined model was constructed by combining the independent predictors and radiomics model. Receiver operating characteristic curve and area under curve (AUC) were used to evaluate the efficacy of each model, and DeLong test was used to compare the efficacy of different models. Results:Significant difference was found in intraplaque hemorrhage, lumen area of stenosis, stenosis diameter, stenosis rate, plaque burden and enhancement rate between culprit and non-culprit plaques (all P<0.05). Multivariate logistic regression analysis confirmed that only intraplaque hemorrhage was the independent predictor for culprit plaques (OR=7.045,95%CI 1.402-35.397, P=0.018). In the validation set, the AUC of the pre-contrast 3D HRMR-VWI model was lower than that of the post-contrast 3D HRMR-VWI model ( Z=-2.01, P=0.044). The AUC of pre+post-contrast 3D HRMR-VWI model was not significantly different from that of post-contrast 3D HRMR-VWI model ( Z=0.79, P=0.427). The AUC showed no significant difference between combined model and pre+post-contrast 3D HRMR-VWI model ( Z=-0.59, P>0.05). The combined model showed the best performance in predicting culprit plaques of middle cerebral artery (AUC=0.939), with the sensitivity, specificity and accuracy of 95.24%, 76.19% and 85.71%. Conclusion:Radiomics based on 3D HRMR-VWI has potential values in identifying culprit plaques in symptomatic patients with middle cerebral atherosclerosis.
