RESUMO

There has been no research on applying gene detection to differential diagnosis of adrenocortical carcinoma (ACC). We attempted to explore a novel auxiliary method for differential diagnosis between ACC with benign adrenocortical adenoma (ACA), based on mutations of target genes in tissues. Nine genes were chosen as target genes, including TP53, CTNNB1, ARMC5, PRKAR1A, ZNRF3, RB1, APC, MEN1, and RPL22. Exons sequencing of target genes were performed in 98 cases of tissue samples by FastTarget technology, including 41 ACC tissues, 32 ACA tissues, and 25 normal adrenal gland tissues. Significant mutations were detected and identified, and the clinical information was collected, for further comparative analysis and application to assist differential diagnosis of ACC. We identified 132 significant gene mutations and 227 significant mutation sites in 37 ACC tissues, much more than ACA and normal adrenal gland tissues. Mutation rates of 6 genes in ACC tissues were obviously higher than ACA tissues, including ZNRF3, ARMC5, TP53, APC, RB1, and PRKAR1A, regarded as high-risk genes. The sum of mutated high-risk genes detected in each sample was denominated sum of high-risk gene mutation (SHGM), and the rates of SHGM > 0 and SHGM > 1 in ACC tissues were 73.0% and 62.2%, respectively, both obviously higher than those in ACA tissues, with significant statistic differences. Especially for 8 cases of ACC with diameter < 5 cm, SHGM > 0 and SHGM > 1 were found in 6 samples (75%) and 4 samples (50%), respectively. However, no relevance was found between SHGM and clinical characteristics of ACC. We identified 6 high-risk genes in ACC tissues, with significantly higher mutation rates than ACA or normal adrenal gland tissues. The sum of mutated high-risk genes detected in ACC tissues was denominated SHGM, which was potential to assist the differential diagnosis of ACC with ACA, especially for the small-size ACC.

RESUMO

OBJECTIVE: To explore the procedure of selective internal pudendal arteriography (IPA) and its application in the diagnosis of arteriogenic erectile dysfunction (AED). METHODS: We performed selective IPA for 62 patients highly suspected of AED with abnormal nocturnal penile tumescence (NPT) and peak systolic velocity (PSV) of the penile cavernosal artery < 25 ml/s. Using digital subtraction angiography, we assessed the stenosis of the main internal pudendal artery and measured the lengths of the dorsal penile arteries and cavernosal arteries. RESULTS: Of the total number of patients, 21 were found with normal internal pudendal arteries, dorsal penile arteries and cavernosal arteries, 7 with abnormal pudendal arteries and atherosclerotic lesions, 37 with inadequately visualized dorsal penile arteries and/or cavernosal arteries, and 3 with both abnormal pundendal and dorsal penile arteries or inadequately visualized cavernosal arteries. No complications were observed except for 3 cases of subcutaneous hematoma at the puncture site. CONCLUSIONS: Selective IPA can display the morphological features of internal pudendal, dorsal penile and cavernosal arteries and help to localize arterial lesions and evaluate blood supply in the penile artery. Therefore, it is a safe and reliable method for the diagnosis of AED.

RESUMO

BACKGROUND: It is usually difficult to identify stroke pathogenesis for single lenticulostriate infarction with nonstenotic middle cerebral artery (MCA). Our aim is to differentiate the two pathogeneses, non-branch atheromatous small vessel disease and branch atheromatous disease (BAD) by high-resolution magnetic resonance imaging (HR-MRI). METHODS: Thirty-two single lenticulostriate infarction patients with nonstenotic MCA admitted to the China-Japan Friendship Hospital from December 2014 to August 2017 were enrolled for retrospective analysis. National Institutes of Health Stroke Scale (NIHSS), modified Rankin Scale (mRS), atherosclerotic risk factors, imaging features, and the characteristic of MCA vessel wall in HR-MRI were evaluated. RESULTS: MCA plaques were detected in 15(46.9%) patients which implied BAD and 8 of 15 (53.3%) patients had plaques location in upper dorsal side of the vessel wall. Patients with HR-MRI identified plaques had a significantly larger infarction lesion length (1.95 ± 0.86 cm versus 1.38 ± 0.55 cm; P = 0.031) and larger lesion volume (2.95 ± 3.94 cm3 versus 0.90 ± 0.94 cm3; P = 0.027) than patients without plaques. Patients with HR-MRI identified plaques had a significant higher percentage of proximal lesions than patients without plaques (P = 0.055). However, according to the location of MCA plaques, there were no significant differences in terms of imaging features, NIHSS and mRS. CONCLUSION: We demonstrated high frequency of MCA atheromatous plaques visualized in single lenticulostriate infarction patients with nonstenotic MCA by using HR-MRI. Patients with HR-MRI identified plaque presented larger infarction lesions and more proximal lesions than patients without plaque, which were consistent with imaging features of BAD. HR-MRI is an important and effective tool for identifying stroke etiology in patients with nonstenotic MCA.

RESUMO

This study aims to explore the effects of shRNA-mediated silencing on Pyruvate kinase type M2 (PKM2) gene during aerobic glycolysis in colorectal cancer (CRC) cells. CRC tissues and adjacent normal tissues were obtained from 136 patients diagnosed with qRT-PCR, Western blotting, and immunohistochemistry (IHC) were performed to detect mRNA and protein expressions of PKM2. CRC cells were divided into a blank, vector, and PKM2-shRNA groups. Hexokinase (HK) and PKM2 activity were both determined by glucose-6-phosphate dehydrogenase (G-6-PD) coupled colorimetric assay and enzyme coupling rate method. The extracellular lactate concentration was measured by ultraviolet spectrophotometer and caspase activity was measured using spectrophotometry. The proliferation, cell cycle, apoptosis, invasion, and migration of CRC cells were detected by cell counting kit-8 (CCK-8) assay, flow cytometry, transwell assay, and scratch test. Three groups of nude mice were injected with 0.2 mL single-cell suspension from the blank, vector, and PKM2-shRNA groups, respectively. PKM2 protein content in CRC tissues was higher than that in adjacent normal tissues. Results showed that the PKM2-shRNA group exhibited significantly lower mRNA and protein expressions of PKM2, decreased PKM2 activity, reduced lactate metabolism level, increased cell apoptosis rate, elevated caspase-3 and caspase-9 activity, weakened proliferation, and a reduction in cell invasion and migration ability compared to the vector and blank groups. The optical density (OD) value was lower in the PKM2-shRNA group than in the blank and vector groups. These findings indicate that shRNA-mediated silencing of PKM2 gene promotes apoptosis and inhibits aerobic glycolysis, proliferation, migration, and invasion in CRC cells. J. Cell.

RESUMO

To verify the hypothesis that upregulation of microRNA-31 (miR-31) targeting integrin α5 (ITGA5) suppresses tumor cell invasion and metastasis by indirectly regulating phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway in human SGC7901 gastric cancer (GC) cells. The miRTarBase was used to predict whether ITGA5 is the target gene of miR-31, which was further confirmed by luciferase reporter gene assay. The SGC7901 GC cells were divided into five groups including the blank, miR-31 mimic, miR-31 mimic control, miR-31 inhibitor, and miR-31 inhibitor control groups. Reverse transcriptase-polymerase chain reaction (RT-PCR), western blotting, cell scratch test, and transwell assays were respectively performed in our study. TGA5 was found as the target gene of miR-31. The RT-PCR detection revealed that, compared with the blank group, ITGA5 messenger RNA (mRNA) expression decreased in the miR-31 mimic group, but increased in the miR-31 inhibitor group. The western blotting examination suggested that the expressions of ITGA5, PI3K, and AKT proteins reduced in the miR-31 mimic group, but enhanced in the miR-31 inhibitor group when compared to the blank group, respectively. The cell scratch and transwell assays indicated that the miR-31 expressions were negatively associated with GC cell migration and invasion. Besides, RT-PCR combined with western blotting demonstrated that the miR-31 expressions were higher in the normal tissues than those in the GC tissues, while the ITGA5 mRNA and protein showed lower expression in the normal tissues than they did in the GC tissues. Our study concluded that upregulation of miR-31 targeting ITGA5 may suppress tumor cell invasion and metastasis by indirectly regulating PI3K/AKT signaling pathway in human SGC7901 GC cells.

RESUMO

PURPOSE: To prospectively determine the feasibility of flat-detector (FD) computed tomography (CT) perfusion to measure hepatic blood volume (BV) in the angiography suite in patients with hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Twenty patients with HCC were investigated with conventional multislice and FD CT perfusion. CT perfusion was carried out on a multislice CT scanner, and FD CT perfusion was performed on a C-arm angiographic system, before transarterial chemoembolization procedures. BV values of conventional and FD CT perfusion were measured within tumors and liver parenchyma. The arterial perfusion portion of CT perfusion BV was extracted from CT perfusion BV by multiplying it by a hepatic perfusion index. Relative values (RVs) for CT perfusion arterial BV and FD CT perfusion BV (FD BV) were defined by dividing BV of tumor by BV of parenchyma. Relationships between BV and RV values of these two techniques were analyzed. RESULTS: In all patients, both perfusion procedures were technically successful, and all 33 HCCs larger than 10 mm were identified with both imaging methods. There were strong correlations between the absolute values of FD BV and CT perfusion arterial BV (tumor, r = 0.903; parenchyma, r = 0.920; both P < .001). Bland-Altman analysis showed a mean difference of -0.15 ± 0.24 between RVs for CT perfusion arterial BV and FD BV. CONCLUSIONS: The feasibility of FD CT perfusion to assess BV values of liver tumor and surrounding parenchyma in the angiographic suite was demonstrated.

RESUMO

Intravenous thrombolysis with recombinant tissue plasminogen activator (rtPA) is the primary treatment for ischemic stroke. However, rtPA treatment can substantially increase blood-brain barrier (BBB) permeability and susceptibility to hemorrhagic transformation. Herein, the mechanism underlying the side effects of rtPA treatment is investigated and demonstrated that ferroptosis plays an important role. The ferroptosis inhibitor, liproxstatin-1 (Lip) is proposed to alleviate the side effects. A well-designed macrocyclic carrier, glucose-modified azocalix[4]arene (GluAC4A), is prepared to deliver Lip to the ischemic site. GluAC4A bound tightly to Lip and markedly improved its solubility. Glucose, modified at the upper rim of GluAC4A, imparts BBB targeting to the drug delivery system owing to the presence of glucose transporter 1 on the BBB surface. The responsiveness of GluAC4A to hypoxia due to the presence of azo groups enabled the targeted release of Lip at the ischemic site. GluAC4A successfully improved drug accumulation in the brain, and Lip@GluAC4A significantly reduced ferroptosis, BBB leakage, and neurological deficits induced by rtPA in vivo. These findings deepen the understanding of the side effects of rtPA treatment and provide a novel strategy for their effective mitigation, which is of great significance for the treatment and prognosis of patients with ischemic stroke.

RESUMO

PURPOSE: To explore the significance of quantitative digital subtraction angiography (DSA; Q-DSA) in the assessment of chemoembolization endpoints. MATERIALS AND METHODS: Twenty patients with hepatocellular carcinoma treated with chemoembolization were included in the study. All DSA series before and after chemoembolization were postprocessed with Q-DSA. The maximal enhancement and time to peak (TTP) were measured for several homologous anatomic landmarks, including the origin and embolized site of the tumor-feeding artery, parenchyma of the tumor, and ostia of the pre- and postprocedure catheter. The TTP, tumor blood supply time, and maximal enhancement of the time density curve (TDC) were analyzed. RESULTS: Of the 20 DSA series collected, 18 were successfully postprocessed. The TTPs of the landmarks before and after treatment were 3.60 seconds±1.02 and 3.57 seconds±0.78 at the ostia of the catheter, 3.91 seconds±1.01 and 4.09 seconds±1.14 at the origin site of the tumor-feeding artery, and 4.07 seconds±1.02 and 5.60 seconds±1.56 s the embolized site of the main tumor-feeding artery, respectively. Statistical differences were detected between pre- and postprocedural TTP of the embolized site of the feeding artery (P<.01), as well as between pre- and postprocedural tumor blood supply time (P<.01). The mean maximal TDC enhancements of selected tumor spots were 3.01 units±1.04 and 0.81 units±0.35 before and after the procedure (P<.01), respectively. CONCLUSIONS: Q-DSA may provide a feasible quantitative measurement in the assessment of chemoembolization endpoints.

RESUMO

To investigate the clinicopathological characteristics of metanephric adenoma (MA), we analyzed the clinical and pathological data of metanephric adenoma. A 39-year old woman with asymptomatic right kidney tumor for 4 years was admitted to the hospital. A tumor with the largest diameter of 28 mm in the right kidney was homogeneously enhanced on CT. The tumor was distinctly increased as compared with 4 years before. The diagnosis was right kidney tumor. Nephron-sparing surgery was given after general anaesthesia. And the relative literature was reviewed. The tumor was homogeneous, with integrity tegument, and a grey cutting surface. Histopathologically, the tumor cells formed an adenoid or papillary pattern and contained psammoma bodies. Immunohistologically, they were positive for AE1/AE3, vimentin and WT1, negative for CK7, EMA and RCC. Pathological diagnosis was metanephric adenoma. The follow-up data of 24 months were available and without recurrence. MA is peculiar. It is difficult to get the final diagnosis of MA only by imaging characters. Nephron-sparing surgery is eligible for the treatment of MA. Considering the uncertainty of the biological behavior and cellular origin of MA, a long-term active surveillance is necessary.

RESUMO

OBJECTIVE: To discuss perioperative treatment and cardiac function changes after medicine and surgical treatment of pheochromocytoma patients with severe catecholamine cardiomyopathy. METHODS: Five pheochromocytoma patients with severe catecholamine cardiomyopathy in our hospital for the past 5 years were studied, their general characteristics, clinical manifestations, diagnosis tests summarized and the cardiac function changes before and after the treatment evaluated. RESULTS: All the 5 patients were diagnosed definitely before operation. After medication, left ventricular ejection fraction (LVEF) of the 5 patients improved and 4 patients' LVEF increased 7-10 days after operation compared with after medication, and one patient's LVEF improved after 3 months. CONCLUSION: Pheochromocytoma patients with severe catecholamine cardiomyopathy should have adequate medication, and their abnormal cardiac function would be reversed after surgical treatment.

RESUMO

OBJECTIVE: To analyze the complications of laparoscopic surgery for the past 11 years in the Urology Department of Peking Union Medical College Hospital. METHODS: The laparoscopic surgery of 5 386 cases from Jan. 2002 to Dec. 2012 was statistically analyzed. The patient's gender, age, surgery mode, blood loss, complications, total length of hospital stay, postoperative hospital stay and other data were analyzed. RESULTS: There were 5 386 cases in this group aged 8-86 years (the mean age: 49.0 years; 2 651 cases were male and 2 735 female). Of all the cases, 2 411 were of adrenal surgery, accounting for 44.7%, 167 of retroperitoneal tumor resection , accounting for 3.1%, 763 of radical nephrectomy surgery, accounting for 14.2%, 441 of partial nephrectomy surgery, accounting for 8.2%, 784 of renal cyst surgery, accounting for 14.6%; 279 of semi-urinary tract resection, accounting for 5.2%; 74 of renal pelvis and ureter plasty, accounting for 1.4%; 141 of radical prostatectomy surgery, accounting for 2.6%, 71 of cystectomy surgery, accounting for 1.3% and 255 of other surgery, accounting for 4.7%. The blood loss was 10-3 000 mL (average: 97.5 mL ) and the surgery requiring blood transfusion treatment involved 270 patients. The total hospital stay was 3-133 days (average: 18 days) and postoperative hospital stay was 2-35 days (average: 6.3 days). All kinds of complications occured in 346 cases (6.42%), of which 198 were of peritoneal injury, 12 of pleural injury; 72 of subcutaneous emphysema, 24 of urinary fistula, 15 of inferior vena cava injury, 6 of pancreatic fistula 10,of lymphatic fistula, 8 of wound delayed healing and 1 of, intestinal fistula. The incidence of the complications and blood transfusion showed a downward trend according to stratified analysis each year. CONCLUSION: The laparoscopic surgery coveres almost all treatment of urological diseases. The complications are different in different types of surgery at different times, but generally no serious complications occurr. The incidence of complications is in a downward trend as the laparoscopic technique level improves.

RESUMO

OBJECTIVE: To explore the diagnosis and treatment of tuberous sclerosis complex complicated with renal angiomyolipoma. METHODS: The clinical data of 22 patients with tuberous sclerosis complex complicated with renal angiomyolipoma were analyzed retrospectively. RESULTS: There were 12 males and 10 females with a mean age of 23 (1-46) years. All of them had bilateral multiple renal angiomyolipomas. The mean tumor size was 8.5 (0.7-18.0) cm in diameter. The presence or absence of clinical symptoms showed a significant correlation with tumor size.Eight patients with angiomyolipoma under 4 cm in diameter were continuously monitored at an outpatient clinic. There were 8 patients with lesions of 4-10 cm.Five of them underwent nephron-sparing surgeries and another 3 monitored at an outpatient clinic. There were 6 patients with tumor over 10 cm. Three of them underwent transcatheter arterial embolization and one case took rapamycin after embolization.One patient with concurrent renal cell carcinoma underwent partial nephrectomy. Chronic renal failure occurred in one case dying of pulmonary lymphangiomyomatosis with serious hemoptysis. During a mean follow-up of 25 months, neither severe renal hemorrhage nor symptomatic aggravation was found.In the case of rapamycin, there was 10% reduction in the size of angiomyolipoma. CONCLUSIONS: Most cases of tuberous sclerosis complex are complicated with bilateral multiple renal angiomyolipoma. The small lesions under 4 cm in diameter may be monitored at an outpatient clinic.For those larger (>4 cm) or symptomatic ones, medication, embolization or surgery is necessary.

RESUMO

BACKGROUND: Diabetic cardiomyopathy (DCM) causes the myocardium to rely on fatty acid ß-oxidation for energy. The accumulation of intracellular lipids and fatty acids in the myocardium usually results in lipotoxicity, which impairs myocardial function. Adipsin may play an important protective role in the pathogenesis of DCM. The aim of this study is to investigate the regulatory effect of Adipsin on DCM lipotoxicity and its molecular mechanism. METHODS: A high-fat diet (HFD)-induced type 2 diabetes mellitus model was constructed in mice with adipose tissue-specific overexpression of Adipsin (Adipsin-Tg). Liquid chromatography-tandem mass spectrometry (LC-MS/MS), glutathione-S-transferase (GST) pull-down technique, Co-immunoprecipitation (Co-IP) and immunofluorescence colocalization analyses were used to investigate the molecules which can directly interact with Adipsin. The immunocolloidal gold method was also used to detect the interaction between Adipsin and its downstream modulator. RESULTS: The expression of Adipsin was significantly downregulated in the HFD-induced DCM model (P < 0.05). Adipose tissue-specific overexpression of Adipsin significantly improved cardiac function and alleviated cardiac remodeling in DCM (P < 0.05). Adipsin overexpression also alleviated mitochondrial oxidative phosphorylation function in diabetic stress (P < 0.05). LC-MS/MS analysis, GST pull-down technique and Co-IP studies revealed that interleukin-1 receptor-associated kinase-like 2 (Irak2) was a downstream regulator of Adipsin. Immunofluorescence analysis also revealed that Adipsin was co-localized with Irak2 in cardiomyocytes. Immunocolloidal gold electron microscopy and Western blotting analysis indicated that Adipsin inhibited the mitochondrial translocation of Irak2 in DCM, thus dampening the interaction between Irak2 and prohibitin (Phb)-optic atrophy protein 1 (Opa1) on mitochondria and improving the structural integrity and function of mitochondria (P < 0.05). Interestingly, in the presence of Irak2 knockdown, Adipsin overexpression did not further alleviate myocardial mitochondrial destruction and cardiac dysfunction, suggesting a downstream role of Irak2 in Adipsin-induced responses (P < 0.05). Consistent with these findings, overexpression of Adipsin after Irak2 knockdown did not further reduce the accumulation of lipids and their metabolites in the cardiac myocardium, nor did it enhance the oxidation capacity of cardiomyocytes expose to palmitate (PA) (P < 0.05). These results indicated that Irak2 may be a downstream regulator of Adipsin. CONCLUSIONS: Adipsin improves fatty acid ß-oxidation and alleviates mitochondrial injury in DCM. The mechanism is related to Irak2 interaction and inhibition of Irak2 mitochondrial translocation.

RESUMO

OBJECTIVE: To derive the Chinese medicine (CM) syndrome classification and subgroup syndrome characteristics of ischemic stroke patients. METHODS: By extracting the CM clinical electronic medical records (EMRs) of 7,170 hospitalized patients with ischemic stroke from 2016 to 2018 at Weifang Hospital of Traditional Chinese Medicine, Shandong Province, China, a patient similarity network (PSN) was constructed based on the symptomatic phenotype of the patients. Thereafter the efficient community detection method BGLL was used to identify subgroups of patients. Finally, subgroups with a large number of cases were selected to analyze the specific manifestations of clinical symptoms and CM syndromes in each subgroup. RESULTS: Seven main subgroups of patients with specific symptom characteristics were identified, including M3, M2, M1, M5, M0, M29 and M4. M3 and M0 subgroups had prominent posterior circulatory symptoms, while M3 was associated with autonomic disorders, and M4 manifested as anxiety; M2 and M4 had motor and motor coordination disorders; M1 had sensory disorders; M5 had more obvious lung infections; M29 had a disorder of consciousness. The specificity of CM syndromes of each subgroup was as follows. M3, M2, M1, M0, M29 and M4 all had the same syndrome as wind phlegm pattern; M3 and M0 both showed hyperactivity of Gan (Liver) yang pattern; M2 and M29 had similar syndromes, which corresponded to intertwined phlegm and blood stasis pattern and phlegm-stasis obstructing meridians pattern, respectively. The manifestations of CM syndromes often appeared in a combination of 2 or more syndrome elements. The most common combination of these 7 subgroups was wind-phlegm. The 7 subgroups of CM syndrome elements were specifically manifested as pathogenic wind, pathogenic phlegm, and deficiency pathogens. CONCLUSIONS: There were 7 main symptom similarity-based subgroups in ischemic stroke patients, and their specific characteristics were obvious. The main syndromes were wind phlegm pattern and hyperactivity of Gan yang pattern.

RESUMO

OBJECTIVE: To compare the efficacies of portal vein stenting and transcatheter arterial chemoembolization (TACE) combined therapy performed with or without endovascular implantation of iodine-125 (125I) seeds strand in patients with hepatocellular carcinoma (HCC) and main portal vein tumor thrombus (MPVTT). METHODS: One-hundred-and-six patients with HCC complicated by MPVTT who were treated with portal vein stents and TACE, either with (Group A, n=56) or without (Group B, n=50) endovascular implantation of 125I seeds strand, between July 2005 and April 2011, were retrospectively analyzed. Overall survival, stent patency, and procedure-related adverse events were compared between the two groups. RESULTS: The technical success rate was 100% for placement of 125I seeds strands and stents in the obstructed main portal vein. No serious procedure-related adverse events were recorded. Group A had significantly higher median survival (335 days vs. group B: 146 days; P=0.001, hazard ratio (HR)=2.244). Additionally, group A had significantly higher median stent patency (400 days vs. group B: 190 days; P=0.005, HR=2.479). CONCLUSION: The combination therapeutic strategy of portal vein stenting and TACE with endovascular implantation of 125I seeds strands improves the survival of HCC patients with MPVTT complication.

RESUMO

Background: Glioblastoma (GBM) is widely known as a classical kind of malignant tumor originating in the brain with high morbidity and mortality. Targeted therapy has shown great promise in treating glioblastoma, but more promising targets, including effective therapeutic targets, remain to be identified. 18A (KIF18A) is a microtubule-based motor protein that is dysregulated and involved in the progression of multiple human cancers. However, the possible effects of KIF18A on GBM progression are still unclear. Methods: We performed DEG analysis, medical data analysis, and network analysis to identify critical genes affecting glioma progression. We also performed immunohistochemical analysis of the KIF18A levels in 94 patients with glioblastoma and the associated surrounding tissues. Patients were divided into two groups according to the high and low expression. Using a clinical analysis, we showed the potential associations between KIF18A expression and clinical characteristics of 94 GBM patients. We then investigated the effects of KIF18A on GBM cell proliferation by colony establishment, MTT, and immune blogging. The possible effect of KIF18A on GBM tumor growth was determined in mice. Results: We identified KIF18A as a potential gene affecting GBM progression. We further demonstrated that GBM tissues expressed KIF18A much higher, and its presentation was associated with recurrence in glioblastoma patients. We believe KIF18A promotes GBM cell proliferation. Conclusion: We demonstrated that KIF18A could be a promising target in treating GBM.

RESUMO

BACKGROUND: Intracranial tuberculoma is a rare and serious type of tuberculosis, which mostly occurs in the frontoparietal and cerebellar hemispheres, with predominance in the gray-white matter junction area, while tuberculomas only in the cistern are extremely rare with only a few reported cases in the literature. We describe a unique case of isolated tuberculoma in the suprasellar cistern, with only right ocular motility disorder and upper eyelid ptosis. CASE SUMMARY: A 5-year-old boy without any medical history presented with right ocular motility disorder and upper eyelid ptosis one month ago. He had no history of fever, headache, vomiting, convulsions, or limb weakness. Neurological examination showed right third cranial nerve palsy with restrictions of eye movements and ptosis, pupil dilation and negative light reflex. Imaging suggested a space-occupying lesion in the suprasellar cistern with calcification and ring-enhancement. Moreover, no Mycobacterium tuberculosis was found in cerebrospinal fluid by polymerase chain reaction (PCR). The lesion was initially diagnosed as a tumor, while postoperative pathology combined with PCR indicated tuberculoma. The patient continued postoperative anti-tuberculosis treatment. At present, the patient's condition is stable and the symptoms are partially relieved compared with those before surgery. CONCLUSION: This case confirmed that isolated intracranial tuberculoma can occur in the suprasellar cistern. Therefore, for space-occupying lesions in the suprasellar cistern, tuberculoma should be included in the differential diagnosis even if there is no history or indication of tuberculosis infection.

RESUMO

BACKGROUND: Non-specific low back pain (NS-LBP) is a serious public health problem. Tai Chi is promising in reducing the risk of falls and alleviating symptoms in this population. OBJECTIVE: To investigate the effect of Tai Chi on gait and dynamic balance in elderly women with NS-LBP. METHODS: 20 women (age > 65 yr.) with NS-LBP were randomly assigned to a Tai Chi group (n= 10) or a control group (n= 10). The Tai Chi group practiced Tai Chi exercise 3 times a week for 6 weeks. Each session lasted 60 minutes. Pain, spatiotemporal gait features and dynamic balancing capacity were assessed at 0 and 6 weeks. RESULTS: Compared to the control group at 6 weeks, the Tai Chi group had a significant decrease in VAS (p= 0.027) and stride width (p= 0.019), significant improvement in gait velocity, stride length (p< 0.001). Regarding dynamic balance capacity, the Tai Chi group had significant improvements in anterior (Left: p= 0.001; Right: p= 0.038), postero-lateral (Left: p< 0.001; Right: p= 0.038), and postero-medial (Left: p= 0.015; Right: p= 0.018). CONCLUSION: 6-week Tai Chi can relieve pain and improve gait and dynamic balance in elderly women with NS-LBP, which suggests Tai Chi could be a promising rehabilitation intervention to reduce the risk of falls in this population.

RESUMO

We explored the mechanisms and molecular targets of Ejiao Siwu Decoction (EJSW) for treating primary immune thrombocytopenia (ITP) using network pharmacology and molecular docking. Active compounds of EJSW were identified by high-performance liquid chromatography-diode array detector (HPLC-DAD) and high-performance liquid chromatography-mass spectrometry (HPLC-MS) and their targets were obtained from HERB and SwissTargetPrediction, and ITP targets were obtained from Comparative Toxicogenomics Database (CTD) and GeneCards. STRING and Cytoscape were used for protein-protein interaction (PPI) network analysis. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses by WebGestalt yielded a gene-pathway network, Autodock molecular docking was applied to screen targets and active compounds, and cytokines were detected using a cytometric bead array (CBA) human inflammation kit. We identified 14 compounds and 129 targets, and 1,726 ITP targets. RAC-alpha serine/threonine-protein kinase (AKT1), tumour necrosis factor (TNF), interleukin-6 (IL6), caspase-3 (CASP3) and tumour suppressor protein (TP53) were core targets (nodes and edges). Functional annotation identified cofactor binding and coenzyme binding, and 20 significantly enriched pathways. Active compounds of EJSW were successfully docked with ITP targets. Tumour necrosis factor alpha (TNF-α) and interleukin-1 beta (IL-1ß) were upregulated in ITP patients, vascular endothelial growth factor A (VEGF-A) and vascular endothelial growth factor D (VEGF-D) were downregulated, and EJSW treatment reversed these trends. EJSW may regulate key ITP targets based on the in silico analyses, and protect vascular integrity through AGE-RAGE signalling, complement and coagulation cascades, and VEGF signalling by downregulating TNF-α, IL-1ß and other inflammatory factors.

RESUMO

Using the four periods of land use data and socio-economic statistics of Lanzhou City in 1995, 2005, 2015 and 2018, we examined the evolution characteristics and driving forces of urban land use in Lanzhou, with expansion intensity index, Logistic regression, and principal component analysis method. Based on the multi-agent model, the expansion of urban land use in Lanzhou under multiple scenarios in 2025 was simulated using Netlogo software. The results showed that the intensity and scale of urban land expansion in Lanzhou City from 1995 to 2018 showed an increasing trend, with a total of 307 km2 of cultivated land and water area. The expansion of urban land in Lanzhou City was significantly related to regional GDP, social fixed asset investment, population density, population, policy, and terrain. The multi-agent model on the Netlogo software could simulate the expansion trend of urban land in Lanzhou, which provided a reliable simulation method for the expansion of valley-type cities. From 2020 to 2025, urban land use under the comprehensive development scenario, natural expansion development scenario, ecological and farmland protection development scenario all showed an increasing trend. The scale of expansion would range between 42.6-134.3 km2. The expansion mode would mainly be infilled expansion. Our results could provide decision support for the land space planning and ecological environment layout optimization for Lanzhou City.
