RESUMEN

Objective:To explore the etiology and treatment of craniopharyngioma with aneurysm.Methods:Seven cases of craniopharyngioma with aneurysm from March 2014 to October 2019 treated in Sanbo Brain Hospital, Capital Medical University were retrospectively analyzed. Among the 7 patients, there were 5 males and 2 females. There were 4 cases of recurrent craniopharyngiomas, 1 case of primary tumor and 2 cases of non-recurrence tumor. Three patients with blood blister-like aneurysms were treated with microsurgical suture after craniopharyngioma resection. Among the three cases with internal carotid artery fusiform aneurysm, 1 case underwent craniopharyngioma resection after internal maxillary artery-radial artery-middle cerebral artery bypass and isolation of the aneurysm; 1 case only underwent internal maxillary artery-radial artery-middle cerebral artery bypass and isolation of the aneurysm for non-recurrence tumor; 1 case underwent craniopharyngioma resection and dynamic observation of aneurysm. One case with a cystic aneurysm of the middle cerebral artery was clipped and the craniopharyngioma did not relapse.Results:All patients had no serious postoperative complications. During the follow-up period, there was no recurrence of craniopharyngioma, no recurrence of treated aneurysms, and the stability of aneurysms was observed.Conclusions:Inflammatory stimulation of craniopharyngioma cystic fluid and operation itself are the important reasons for the occurrence of aneurysms after craniopharyngioma surgery. Choosing appropriate surgical methods can complete the removal of craniopharyngioma and the treatment of aneurysms at one time.

RESUMEN

Objective:To retrospectively summarize the imaging and clinical features of craniopharyngioma in order to improve the preoperative diagnosis level.Methods:One hundred and twenty-seven patients with craniopharyngioma diagnosed by pathology in Sanbo Brain Hospital, Capital Medical University from March 2019 to June 2021 were selected and the pathological coincidence rate of imaging diagnosis were analyzed.Results:The coincidence rate of MRI diagnosis was 89.3%. The coincidence rate of CT diagnosis was 71.5%. On T 2WI and T 1WI enhanced sequences, the solid portion of the tumor may showed uneven hyperintensity, diffuse striation and spotty hyperintensity. MRI sagittal view was helpful in showing small tumors, but less sensitive to calcification than CT. MRI enhancement was very important, especially for patients with solid lesions. Conclusions:The imaging findings of craniopharyngioma are diverse. Some characteristic manifestations provide important information for the diagnosis and differential diagnosis of craniopharyngioma, which can improve the diagnostic accuracy combined with clinical data.

RESUMEN

OBJECTIVE@#To explain the clinicobiological heterogeneity of NPM1 mutated (NPM1mut) acute myeloid leukemia (AML) by analyzing the association between next-generation sequencing (NGS) profiles and MICM characteristics in patients with this AML subtype.@*METHODS@#Data of 238 NPM1mut patients with available NGS information on 112 genes related to blood disease was collected, and χ2 test and nonparametric test were used to analyze the distribution association between NGS-detecting mutations and conventional MICM parameters.@*RESULTS@#In entire NPM1mut cohort, totaling 240 NPM1 mutation events were identified, of whom 10 (10/240, 4.2%) were missense mutations, which did not involve any W288 or W290 locus and were found exclusively in NPM1mut/FLT3-ITD- group. All but one of these missense mutations (9/10, 90%) were accompanied by AML subtype-defining recurrent cytogenetic or molecular abnormalities, of which 7 cases were in the low risk and 2 in the high risk. NPM1mut occurred solely as an insertion/deletion (indel) type in the NPM1mut/FLT3-ITD+ group. The incidence of favorable plus unfavorable karyotypes in NPM1mut/FLT3-ITD- group was higher than in NPM1mut/FLT3-ITD+ group (6.4% vs. 0, P=0.031). The positive rates of CD34 and CD7 in NPM1mut/FLT3-ITD+ group were significantly higher than in NPM1mut/FLT3-ITD- group (CD34: 47.9% vs. 20.6%, P<0.001; CD7: 61.5% vs. 29.9%, P<0.001). Logistic analysis showed that FLT3-ITD independently predicted for CD34+ and CD7+ [odds ratio (OR)=5.29, 95%CI: 2.64-10.60, P<0.001; OR=3.47, 95%CI: 1.79-6.73, P<0.001; respectively]. Ras-pathway mutations independently predicted for HLA-DR+ (OR=4.05, 95%CI: 1.70-9.63, P=0.002), and KRAS mutation for MPO- (OR=0.18, 95%CI: 0.05-0.62, P=0.007). TET2/IDH1 mutations independently predicted for CD34- and CD7- (OR=0.26, 95%CI: 0.11-0.62, P=0.002; OR=0.30, 95%CI: 0.14-0.62, P=0.001; respectively), and MPO+ (OR=3.52, 95%CI: 1.48-8.38, P=0.004). DNMT3A-R882 independently predicted for CD7+ and HLA-DR+ (OR=3.59, 95%CI: 1.80-7.16, P<0.001; OR=13.41, 95%CI: 4.56-39.45, P<0.001; respectively), and DNMT3A mutation for MPO-(OR=0.35, 95%CI: 1.48-8.38, P=0.004).@*CONCLUSION@#Co-existing FLT3-ITD in NPM1mut AML independently predicts for CD34+ and CD7+, co-existing Ras-pathway mutation for HLA-DR+ and MPO-, co-existing TET2/IDH1 mutation for CD34-, CD7-, and MPO+, and co-existing DNMT3A mutation for HLA-DR+, CD7+, and MPO-, thereby providing a new mechanism explanation for the immunophenotypic heterogeneity of these AML patients.

RESUMEN

@#Non-alcoholic steatohepatitis(NASH)is the most common chronic liver disease. However, the treatment of NASH remains challenging. Apoptosis signal regulating kinases-1(ASK-1)is a member of mitogen-activated protein kinase kinase kinases(MAPKKKs). When the body is stimulated by reactive oxygen species, endoplasmic reticulum stress, calcium influx and extracellular inflammatory signals, c-Jun amino terminal kinases(JNK)and p38 MAPK wiube activated, which then promotes cell proliferation, differentiation, apoptosis and production of inflammatory factors, and causes NASH, fibrosis and other diseases. Therefore, ASK-1 inhibitors can be used to treat NASH. This paper reviews the current treatment methods of NASH, the structure and mechanism of ASK-1, and the research progress of ASK-1 inhibitors in the treatment of NASH in recent years, which aims to explore the guiding significance for the design and development of ASK-1 inhibitors.

RESUMEN

Objective To explore the surgical treatment of spindle aneurysms in V4 segment of vertebral artery. Methods The clinical data, surgical methods and prognosis of 6 patients with V4 spindle aneurysms of vertebral artery admitted from 2011 to November 2018 in Sanbo Brain Hospital were retrospectively analyzed,Results There were 4 males and 2 females aged from 45 to 65 years. Aneurysm rupture and bleeding occurred in 3 cases. Far lateral approach was used in all patients. One case was clipped with window aneurysms, 2 cases were treated with occipital artery (OA)- posterior inferior cerebellar artery (PICA) bypass, and 3 cases were treated with vertebral artery occlusion. Postoperative patients were generally in good condition. Postoperative CT arteriography confirmed that the bypass vessels were unobstructed in 2 cases. All vertebral aneurysms were treated satisfactorily and PICA arteries were preserved. Tracheotomy was performed in 5 patients (1 case was incised before operation). Three patients were removed 3 months after operation. The Glasgow Prognosis Score (GOS) was 4 points. Long-term tracheotomy was performed in 1 case, and GOS score was 3 points. Two patients died 4 months and 3 years after operation. Conclusions Craniotomy is an important method for the treatment of spindle aneurysm of V4 segment of vertebral artery. Different surgical methods should be selected according to the size of the aneurysm, the relationship between the location of the aneurysm and PICA, and the compensation of the vertebral artery.

RESUMEN

@#Insulin as well as glucagon-like peptide 1(GLP-1)and its analogs are commonly used in treating type II diabetes. Both insulin and GLP-1 are endogenous peptides, and have advantages such as high efficiency and selectivity. However, there are some disadvantages to using regular insulin with slow effect, short-time effect and risk of hypoglycemia. Due to the elimination of kidneys and the metabolism of enzymes, the half-life of GLP-1 is so short that neither of them can stabilize glucose. Therefore, it is of great significance to study the long-acting strategy of insulin and GLP-1. Based on the long-acting strategy and pharmacological assessment of peptide drugs, this paper reviewed the latest progress of the related drugs that already on the market and under research to provide references for the design of novel long-acting insulin and GLP-1 analogs.

RESUMEN

@#Glucokinase(GK), which plays a pivotal role in maintaining glucose equilibrium in the human body, emerged as one of the most promising targets for the treatment of diabetes mellitus type 2. Pharmacophore models of glucokinase agonist inhibitors have been generated with a training set of 25 glucokinase agonists(EC50 values from 2 to 78 000 nmol/L)using Discovery studio 2. 5. The best hypothesis contained three hydrogen bond acceptors, one hydrophobic center, and three excluded volumes with a correlation coefficient of 0. 955, cost difference of 60. 5, RMSD of 0. 714. This model was validated by test set, Fischer randomization test and decoy set methods. Pharmacophore model was also utilized as a three dimentional query to screen in-house andrographolide derivative database. New potential GK agonist was obtained therewith, and the hit compound is capable for further screening assay studies. Preliminary biological evaluation suggests that this new pharmacophore model fuctions superiorly in virtual screening.

RESUMEN

AIM@#To identify the glucose lowering ability and chronic treatment effects of a novel coumarin-glucagon-like peptide-1 (GLP-1) conjugate HJ07.@*METHOD@#A receptor activation experiment was performed in HEK 293 cells and the glucose lowering ability was evaluated with hypoglycemic duration and glucose stabilizing tests. Chronic treatment was performed by daily injection of exendin-4, saline, and HJ07. Body weight and HbA1c were measured every week, and an intraperitoneal glucose tolerance test was performed before treatment and after treatment.@*RESULTS@#HJ07 showed well-preserved receptor activation efficacy. The hypoglycemic duration test showed that HJ07 possessed a long-acting, glucose-lowering effect and the glucose stabilizing test showed that the antihyperglycemic activity of HJ07 was still evident at a predetermined time (12 h) prior to the glucose challenge (0 h). The long time glucose-lowering effect of HJ07 was better than native GLP-1 and exendin-4. Furthermore, once daily injection of HJ07 to db/db mice achieved long-term beneficial effects on HbA1c lowering and glucose tolerance.@*CONCLUSION@#The biological activity results of HJ07 suggest that HJ07 is a potential long-acting agent for the treatment of type 2 diabetes.

RESUMEN

<p><b>BACKGROUND</b>Gingerol is the generic term for pungent constituents in ginger, which has been reported to be effective for inhibiting vomiting. We attempted to investigate the antiemetic effect of gingerol and its effective mechanism on substance P and NK(1) receptors in minks.</p><p><b>METHODS</b>The antiemetic effect of gingerol was investigated during a 6-hour observation on a vomiting model in minks induced by cisplatin, (7.5 mg/kg, intraperitoneal). The distribution of substance P and NK(1) receptors in the area postrema and ileum were measured by immunohistochemistry, and the expression of NK(1) receptor in the area postrema and ileum were measured by Western blotting.</p><p><b>RESULTS</b>The frequency of cisplatin induced retching and vomiting was significantly reduced by pretreatment with gingerol in a dose-dependent manner (P < 0.05). Substance P-immunoreactive was mainly situated in the mucosa and submucosa of the ileum as well as in the neurons of the area postrema. The immunoreactive production of NK(1) receptor was mainly situated in the muscular and submucosa of ileum and the neurons of area postrema, gingerol markedly suppressed the increased immunoreactivity of substance P and NK(1)1 receptor induced by cisplatin in a dose-dependent manner (P < 0.05), and exhibited effective inhibition on the increased expression levels of NK(1) receptor in both the ileum and area postrema dose-dependently (P < 0.05).</p><p><b>CONCLUSIONS</b>Gingerol has good activity against cisplatin-induced emesis in minks possibly by inhibiting central or peripheral increase of substance P and NK(1) receptors.</p>
