ABSTRACT

Carotid artery stenosis is an important cause of ischemic stroke. Carotid endarterectomy and carotid artery stenting are the effective methods for treating carotid artery stenosis, but postoperative restenosis remains a challenge. The pathogenesis of postoperative restenosis is currently not fully understood. However, multiple factors, including biomarkers, imaging features, and surgical related factors, have been proven to be associated with postoperative restenosis and can predict the occurrence of postoperative restenosis. This article reviews the predictors of restenosis after carotid endarterectomy and carotid artery stenting.

ABSTRACT

Objective:To investigate the effect and mechanism of NACK knockdown on the proliferation and apoptosis of T-cell acute lymphoblastic leukemia (T-ALL) Jurkat cells. Methods:Lentivirus transfection technology was used to transfect Jurkat cells and knock down NACK gene.Real time fluorescent quantitative PCR and Western blot were used to detect the silencing efficiency of NACK gene.CCK-8 method and flow cytometry were used to detect the effects of NACK knockdown on the proliferation and apoptosis of Jurkat cells.The expressions of protein related with Notch1 pathway, such as Hes1 and c-Myc, were detected by Western blot. Results:After NACK-shRNA was successfully transfected into Jurkat cells by lentiviral vector, the expression of NACK mRNA and protein was reduced signi-ficantly ( P<0.05). Compared with the negative control group and the blank control group, the CCK-8 method showed that the cell proliferation in the experimental group was significantly inhibited [The inhibition rates of cell proliferation in the experimental group, negative control group and blank control group were (37.27±4.48)%, (4.25±2.10)% and (2.43±1.40)%, respectively]( F=132.640, P<0.05), and the flow cytometry test showed that the apoptosis in the experimental group increased significantly [The apoptosis rates of experimental group, negative control group and blank control group were (26.38±3.03)%, (6.07±2.61)% and (3.40±1.98)%, respectively]( F=90.534, P<0.05). Western blot results confirmed that the expression of Notch1 pathway-related proteins Hes1 and c-Myc was down-regulated compared with the negative control group and the blank control group, and the difference was statistically significant ( P<0.05). Conclusions:Targeting silent NACK can down-regulate the expression of Notch1 pathway-related proteins, which leads to the inhibition of Jurkat cell proliferation and increased apoptosis, thereby exerting its anti-T-ALL effect.

ABSTRACT

The clinical application of immune checkpoint inhibitors (ICIs) has significantly improved the prognosis of hepatocellular carcinoma (HCC) patients. With the widespread applica-tion of ICIs in HCC, the management of immune-related adverse events (irAE) gained more and more attention. However, the complicated disease characteristics and various combination therapies in HCC throw out challenges to irAE management. Therefore, the editorial board of the 'Chinese expert consensus on the management of immune-related adverse events of hepatocellular carcinoma treated with immune checkpoint inhibitors (2021 edition)' organizes multidisciplinary experts to discuss and formulate this consensus. The consensus focuses on issues related to HCC irAE manage-ment, and puts forward suggestions, in order to improve standardized and safety clinical medication, so as to maximize the benefits of immunotherapy for patients.

ABSTRACT

Biological denitrification is the most widely used technology for nitrate removal in wastewater treatment. Conventional denitrification requires long hydraulic retention time, and the nitrate removal efficiency in winter is low due to the low temperature. Therefore, it is expected to develop new approaches to enhance the denitrification process. In this paper, the effect of adding different concentrations of Fe₃O₄ nanoparticles on the denitrification catalyzed by Pseudomonas stutzeri was investigated. The maximum specific degradation rate of nitrate nitrogen improved from 18.0 h⁻¹ to 23.7 h⁻¹ when the concentration of Fe₃O₄ increased from 0 mg/L to 4 000 mg/L. Total proteins and intracellular iron content also increased along with increasing the concentration of Fe₃O₄. RT-qPCR and label-free proteomics analyses showed that the relative expression level of denitrifying genes napA, narJ, nirB, norR, nosZ of P. stutzeri increased by 55.7%, 24.9%, 24.5%, 36.5%, 120% upon addition of Fe₃O₄, and that of denitrifying reductase Nap, Nar, Nir, Nor, Nos increased by 85.0%, 147%, 16.5%, 47.1%, 95.9%, respectively. No significant difference was observed on the relative expression level of denitrifying genes and denitrifying reductases between the bacteria suspended and the bacteria adhered to Fe₃O₄. Interestingly, the relative expression level of electron transfer proteins of bacteria adhered to Fe₃O₄ was higher than that of the bacteria suspended. The results indicated that Fe₃O₄ promoted cell growth and metabolism through direct contact with bacteria, thereby improving the denitrification. These findings may provide theoretical support for the development of enhanced denitrification.

ABSTRACT

Objective:To evaluate the effectiveness of multi-disciplinary treatment (MDT) for reducing carbapenem-resistant Enterobacteriaceae (CRE) infections in intensive care unit(ICU).Methods:Patients admitted in the emergency ICU (EICU) and neurosurgical ICU (NICU) of the First People’s Hospital of Lianyungang during January 2018 to December 2019 were enrolled in the study, which was analyzed by historical control study. For patients admitted in 2018, the conventional method was adopted for prevention and control of drug-resistant bacteria (control group, n=1, 076), and for patients admitted in 2019, the MDT was adopted for the prevention and control of CRE (intervention group, n=1, 237). Chi-square test was used to compare the incidence rate of CRE infection, CRE detection rate, rate of rational antibiotic use and compliance with implementation of prevention and control measures between two groups. Results:Compared to control group, the incidence rate of CRE infection in EICU and NICU decreased from 3.45% (14/406) and 3.58% (24/670) to 1.65% (9/547) and 2.32% (16/690) in intervention group, respectively; while the detection rate of CRE decreased from 66.21% (96/145) and 57.72% (86/149) to 41.11% (51/124) and 33.06% (40/121), the pathogens were mainly carbapenem-resistant Klebsiella pneumoniae (CRKP). The rational medication rate of carbapenem antibiotics was significantly increased from 65.00%(78/120) in 2018 to 92.73%(319/344) in 2019 ( χ2=55.382, P<0.05). In addition, the single room isolation rate, the rate of specialized nursing care, the cleaning and disinfection quality of bench surface and the special use rate of articles were also significantly improved( χ2=21.646, 18.116, 39.869 and 19.713, P<0.01). Conclusion:The establishment of multi-department collaborative management based on MDT can effectively improve the prevention and control effect of CRE in ICU and significantly reduce the prevalence of CRE infection.

ABSTRACT

Hypothyroidism is a common adverse reaction in clinical multi-target tyrosine kinase inhibitor (TKI) and may be used as a predictor of efficacy of TKI drugs.Studies show that hypothyroidism is significantly associated with good prognosis in patients with renal cell carcinoma treated with multi-target TKI,which may be related to inhibition of vascular endothelial growth factor receptor pathway,potential off-target effects and inhibition of cell proliferation.Whereas in the patients with hepatocellular carcinoma who received multi-target TKI therapy,hypothyroidism is an indicator of poor prognosis,which is related to the T3/TR pathway regulating liver cancer growth and invasion.The predictive function and mechanism of thyroid hormone levels in different tumor patients receiving multi-target TKI drugs are different,and further research is still needed.

ABSTRACT

Objective To explore the application of limbs and fingers movement combined with moxibustion in patients with PICC catheterization. Methods A total of 346 PICC catheterized patients treated from August 2014 to July 2017 were randomly divided into control group (173 cases) and observation group (173 cases) according to random number table method. The control group was given local hot-wet compression at 3-4 cm of puncture point after 24 h of catheterization, and the observation group was given preventive moxibustion with the direction of the punctured vein at the same site in the control group, and then was given limbs and fingers movement. The levels of serum monocyte chemoattractant protein- 1 (MCP- 1), tumor necrosis factor- α (TNF- α) and interleukin- 8 (IL- 8), hemorheological parameters [rate of high and low shear whole blood viscosity (RBV), rate of plasma specific viscosity (RPV), hematocrit (HCT)] and the incidence rates of mechanical phlebitis and venous thrombosis were compared between the two groups after intervention. Results The levels of MCP-1, TNF-αand IL-8 were (53.03±7.86), (85.93±10.72), (54.65±9.23) ng/L in the observation group, (60.27± 8.45), (94.74±11.36), (63.08±10.07) ng/L in the control group, and there were significant differences (t=8.252, 7.419, 8.117, all P<0.05). The levels of high shear RBV, low shear RBV, RPV and HCT were (3.94 ± 0.85) mPa · s, (6.55 ± 1.22) mPa · s, (1.70 ± 0.54) mPa · s and (43.71 ± 4.82)% respectively in the observation group, (4.18±0.74) mPa·s, (6.97±1.25) mPa·s, (1.92±0.59) mPa·s and (45.13±4.65)%in the control group, and there were significant differences (t=2.789-3.618, P<0.05). The incidence rates of venous thrombosis and phlebitis were 1.16%(2/173) and 5.78%(10/173) respectively in the observation group, 5.78%(10/173) and 13.29%(23/173) in the control group, there were significant differences (χ2=4.230, 5.661, P<0.05).

ABSTRACT

Objective To study the effect of Tamibarotene on the SH-SY5Y cell proliferation inhibition ability and the mRNA and protein expressions of tyrosine kinase receptor a (TrkA) and N-myc (MYCN) in order to provide some experimental bases for the treatment of neuroblastoma.Methods The SH-SY5Y cells were treated with different concentrations of Am80 (0,10,20,40,80,160 μmol/L) for 48 h,then Cell Counting Kit-8 (CCK-8) was used to test the cell proliferation.Reverse transcription PCR(RT-PCR) and Western blot were used to test the mRNA and protein expressions of TrkA and MYCN at 48 hours.Results When the concentration was 10 μmol/L,Am80 had no significant inhibitory effect on SH-SY5Y cells [(3.51 ± 1.68)%,inhibition ratio < 5 %];but when the concentration was 20 μmol/L,it showed weak inhibition [(9.60 ± 1.97) %,inhibition ratio < 10%].The inhibition rate of SH-SY5Y cell proliferation[(57.43 ± 4.95)%] was significantly enhanced at Am80 with a concentration of 80 μmol/L.The concentrations of Am80 could effectively inhibit SH-SY5Y cell proliferation in a dose-dependent manner(P <0.05).The expression of TrkA increased with the increase of Am80 concentration.Am80 significantly decreased the expression of MYCN in SH-SY5Y cells(10 μmol/L:0.65 ±0.05 vs.20 μmol/L:0.36 ±0.06),and the difference was statistically significant(P < 0.05).Conclusions It is suggested that Am80 can effectively inhibit SH-SY5Y cell proliferation in a concentration-dependent manner.The underlying mechanism involves increasing the expression of TrkA by down-regulation of MYCN.

ABSTRACT

Objective To explore the dynamic changes and significance of costimulatory molecules CD40 and lymphocyte subsets in peripheral blood of children with eosinophilic gastroenteritis (EG). Methods The CD40 expression and lymphocyte subsets in peripheral blood were detected by flow cytometry (FCM) in 15 children with EG (acute stage and remission stage) and 15 healthy controls. The level of serum interleukin (IL) -4 was detected by enzyme-linked immunosorbent assay (ELISA). The eosinophil (EOS) was count by blood cell analyzer. Results In acute stage, the children with EG had significantly higher expression of CD40, CD3+, CD4+, CD4+/CD8+, and CD19+CD23+ in peripheral blood, higher serum IL-4 level, higher EOS count and lower CD8+ than in remission stage and control group (P all<0.05). There were no differences between remission stage and control group (P>0.05). In acute stage, the expression of CD40 in peripheral blood in children with EG was positively correlated with the expression of CD4+ and IL-4 (P all<0.05). Conclusions CD40 may be involved in the pathogenesis of EG. That the increase of IL-4 secreted by CD4+ T cells that were induced by CD40 results in abnormal increase of EOS may be one of mechanisms of the pathogenesis of EG.

ABSTRACT

Objective To compare lateral orbital keyhole approach(LOK) with conventional keyhole approach including supraorbital keyhole approach (SOK) and pterional approach(PTK) for exposuring the sellar region and oper-ation ability, to provide theoretical and practical basis for the clinic. Methods From January, 2017 to Feburary, 2018, 15 cadaver head specimens of Chinese (30 sides) fixed by formalin were randomly divided into 3 groups, simu-lating SOK, LOK and PTK, application of frameless neuronavigation system, intersection of the posterior margin of the optic chiasma and the lamina terminalis served as the base point. Six different reference points were selected to radi-ate into the parasellar region of the skull base. The direction of the 2 adjacent reference points were connected to the base point to form a triangle. Six triangles constituted the sellar region to represent the total area. The supratentorial area, ipsilateral area, inferior area and contralateral area were calculated by stacking triangle. The comparison was made between groups. The Salma operation exposure scale was used to simulate the aneurysms of the common parts in the brain and the quantitative scores were performed. Results The total parasellar regions by SOK, LOK and PTK respectively were:(1641.6±295.6)mm2, (1782.3±294.6)mm2 and (1552.5±307.4)mm2. There was no statistical differ-ence(P>0.05); To compare the supratentorial region, SOK and LOK were both bigger than PTK ( P<0.05); To compare the ipsilateral and infratentorial area, LOK and PTK were both bigger than SOK respectively ( P<0.05);To compare the contralateral area, SOK, LOK and PTK were increased in turn (P<0.05). Salma operation exposure scale was used to get the scores:the score of SOK was 29.7 (39.08%), LOK was 37.0 (48.68%), and PTK was 36.1 (47.50%). Conclusion Anatomical analysis displayed that the 3 keyhole approaches showed different exposure of each part the parasellar re-gions, the LOK had a good exposure to the parasellar region and so as the higher maneuverability. But the clinical appli-cation should be comprehensive analysis, pay attention to specific lesions and make an appropriate choice. It has impor-tant clinical significance to improve the prognosis of patients.

ABSTRACT

Objective: To evaluate the safety and effectiveness using adult flexible bronchoscopy via laryngeal mask airway [LMA] under general anesthesia in children aged 2 - 5 years


Design: Retrospective study


Setting: Yuhuangding Hospital, Yantai, China


Subjects: The procedures of bronchoscopy were performed with an adult flexible bronchoscope via LMA under general anaesthesia. Indications and complications were analyzed, retrospectively


Intervention[s]: Expanding the wide use of pediatric flexible bronchoscopy to diagnostic and interventional bronchoscopy


Main outcome measure[s]: Performed using SPSS17.0


Results: The indications for bronchoscopy included tracheal mucous plugs removal in 108 cases with pneumonia, tracheobronchial foreign bodies removal in 82 cases, endobronchial biopsy in 66 cases, bronchoscopic cryosurgery in 23 cases with tracheal granulation tissue formation after long-term endotracheal intubation, balloon dilatation in 11 cases with lobar bronchial stenosis and bronchoscopic management in 12 cases with traumatic tracheobronchial injuries. Complications were reported for 193 cases, with an overall complication rate of 63.9%. The incidence rate was highest in children aged 2 - 3 years, and decreased with age. Hypoxia and post bronchoscopy cough were the most complication in all patients. Acute hypoxia during bronchoscopy happened in 5 [1.6%] cases and was relieved quickly by intermittent withdrawal of the bronchoscope. Most post bronchoscopy cough without respiratory distress or hypoxia could be seen in 188 [62.3%] cases and resolved within four hours after inhalation of budesonide


Conclusion: An adult flexible bronchoscope via LMA could be safely and effectively used for interventional bronchoscopy in 2 - 5 years old children with different kinds of the proximal airway diseases
