ABSTRACT

Objective To explore the effect of ropivacaine combined with dexmedetomidine in transversus abdominis plane block(TAPB)on postoperative stress hormones and cognitive function in patients undergoing laparoscopic radical gastrectomy.Methods A total of 80 patients undergoing laparoscopic radical gastrectomy at the First Affiliated Hospital of Xinxiang Medical University from April to October 2023 were selected as the research subjects.According to different anesthesia methods,the patients were divided into the observation group and the control group,with 40 patients in each group.Patients in the observation group were injected bilaterally with 2.5 g·L-1 ropivacaine and 0.5 μg·kg-1 dexmedetomidine for TAPB,with 20 mL injection on each side.Patients in the control group were injected bilaterally with 2.5 g·L-1 ropivacaine for TAPB,with 20 mL injection on each side.Mean arterial pressure(MAP)and heart rate(HR)were recorded at the time of admission to the operating room(T1),immediately after endotracheal intubation(T2),40 minutes after pneumoperitoneum(T3),and 15 minutes after extubation(T4).Radioimmunoprecipitation was used to detect serum cortisol(COR)level,and enzyme-linked immunosorbent assay was used to measure serum norepinephrine(NE)and epinephrine(E)levels at 1,6,12,and 24 hours after surgery.Visual analog scale(VAS)was used to assess pain at rest,and Ramsay sedation scale(RSS)was used to evaluate sedation depth.The doses of propofol and sufentanil were compared between the two groups.Serum β-amyloid(Aβ)and S100β protein levels at 1 day before surgery,1 and 3 days after surgery were detected by using the enzyme-linked immunosorbent assay,and cognitive function was assessed at the same time points by using the mini-mental state examination(MMSE).Results At T,and T2,there was no significant difference in MAP and HR between the control group and the observation group(P>0.05).At T3 and T4,MAP and HR in the observation group were significantly lower than those in the control group(P<0.05).At 1,6,and 12 hours postoperatively,VAS score in the observation group was significantly lower than that in the control group(P<0.05).At 24 hours postoperatively,there was no significant difference in VAS score between the control group and observation group(P>0.05).At 1 and 6 hours postoperatively,RSS score in the observation group was significantly higher than that in the control group(P<0.05).At 12 and 24 hours postoperatively,there was no significant difference in RSS score between the control group and observation group(P>0.05).At 1,6,and 12 hours postoperatively,COR,NE,and E levels in the observation group were significantly lower than those in the control group(P<0.05).At 24 hours postoperatively,there was no significant difference in COR,NE,and E levels between the control group and observation group(P>0.05).The doses of propofol and sufentanil in the observation group were significantly lower than those in the control group(P<0.05).One day before surgery,there was no significant difference in MMSE score between the control group and observation group(P>0.05).At 1 and 3 days postoperatively,MMSE score in the observation group was significantly higher than that in the control group(P<0.05).One day before surgery,there was no significant difference in serum Aβ and S100β protein levels between the control group and observation group(P>0.05).At 1 and 3 days postoperatively,serum Aβ and S100β protein levels in the observation group were significantly lower than those in the control group(P<0.05).Conclusion Ropivacaine combined with dexmedetomidine in TAPB in radical gastrectomy can significantly reduce postoperative pain,increase sedative effect,prolong the duration of TAPB,and benefit patients'postoperative recovery with reduced cognitive impairment.

ABSTRACT

Objective:To evaluate the effect of superior cervical ganglion block (SCGB) on cardiac function and nucleotide like receptor protein 3 (NLRP3) signaling pathway in a rat model of myocardial ischemia-reperfusion (I/R).Methods:Sixty healthy SPF male Sprague-Dawley rats, weighing 250-300 g, aged 2-3 months, were divided into 4 groups ( n=15 each) using a random number table method: sham operation group (sham group), myocardial I/R group (IR group), myocardial I/R + normal saline group (IR+ NS group), and myocardial I/R + SCGB group (IR+ SCGB group). Myocardial I/R model was developed by ligation of the left anterior descending branch of the coronary artery for 45 min followed by restoration of blood flow in anesthetized aninals. IR+ SCGB group received SCGB (0.25% ropivacaine 0.1 ml) at 10 min before reperfusion once a day for 2 consecutive weeks, while 0.9% sodium chloride was given instead of ropivacaine in IR+ NS group. Blood samples were collected at 24 h and 14 days of reperfusion for determination of serum concentrations of norepinephrine (NE), troponin T (TnT), tumor necrosis factor-alpha (TNF-α), interleukin-18 (IL-18) and IL-1β by enzyme-linked immunosorbent assay. Echocardiography was performed before ischemia and at 14 days of reperfusion, and left ventricular short axis shortening rate (FS), ejection fraction (EF), and cardiac output (CO) were measured. The rats were sacrificed at 14 days of reperfusion and the hearts were taken for determination of the contents of norepinephrine (NE) in myocardial tissues in the infarction area (by enzyme-linked immunosorbent assay), percentage of myocardial fibrosis area (by Masson staining), M1 macrophage marker CD68 + cell count in the infarction area (by immunohistochemical method), and expression of NLRP3 and gasdermin D (GSDMD) in myocardial tissues (by Western blot). Results:Compared with Sham group, the serum concentrations of TnT, TNF-α, IL-18 and IL-1β, percentage of myocardial fibrosis area, and NE levels in serum and myocardial tissues were significantly increased, the expression of NLRP3 and GSDMD in myocardial tissues was up-regulated, CD68 + cell count was increased, and EF, CO and FS were decreased in IR group ( P<0.05). Compared with IR group, the serum concentrations of TnT, TNF-α, IL-18 and IL-1β, percentage of myocardial fibrosis area, and NE levels in serum and myocardial tissues were significantly decreased, the expression of NLRP3 and GSDMD in myocardial tissues was down-regulated, CD68 + cell count was decreased, and EF, CO and FS were increased in IR+ SCGB group ( P<0.05), and no statistically significant changes were found in the parameters mentioned above in IR+ NS group ( P>0.05). Conclusions:SCGB can improve the cardiac function in a rat model of myocardial I/R, and the mechanism may be related to the inhibition of NLRP3 signaling pathway.

ABSTRACT

The skin is the largest organ of the human body, and many visceral diseases will be directly reflected on the skin, so it is of great clinical significance to accurately segment the skin lesion images. To address the characteristics of complex color, blurred boundaries, and uneven scale information, a skin lesion image segmentation method based on dense atrous spatial pyramid pooling (DenseASPP) and attention mechanism is proposed. The method is based on the U-shaped network (U-Net). Firstly, a new encoder is redesigned to replace the ordinary convolutional stacking with a large number of residual connections, which can effectively retain key features even after expanding the network depth. Secondly, channel attention is fused with spatial attention, and residual connections are added so that the network can adaptively learn channel and spatial features of images. Finally, the DenseASPP module is introduced and redesigned to expand the perceptual field size and obtain multi-scale feature information. The algorithm proposed in this paper has obtained satisfactory results in the official public dataset of the International Skin Imaging Collaboration (ISIC 2016). The mean Intersection over Union (mIOU), sensitivity (SE), precision (PC), accuracy (ACC), and Dice coefficient (Dice) are 0.901 8, 0.945 9, 0.948 7, 0.968 1, 0.947 3, respectively. The experimental results demonstrate that the method in this paper can improve the segmentation effect of skin lesion images, and is expected to provide an auxiliary diagnosis for professional dermatologists.

ABSTRACT

Objective:To evaluate the effects of stellate ganglion block (SGB) on the activation of M1 microglia during cerebral ischemia-reperfusion (I/R) in rats.Methods:Fifty-four SPF healthy male Sprague-Dawley rats, aged 8-10 weeks, weighing 240-270 g, were divided into 3 groups ( n=18 each) using a random number table method: sham operation group (group Sham), cerebral I/R group (group IR) and SGB group.Blood vessels were only exposed, without occlusion in group Sham.Cerebral I/R was induced by occlusion of the middle cerebral artery for 90 min followed by reperfusion in group IR.Cervical sympathetic trunk transaction was performed to induce left SGB immediately after onset of reperfusion in group SGB.Blood samples were collected from the apex of the heart at 6, 12 and 24 h of reperfusion for determination of the concentrations of tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β in the serum (using enzyme-linked immunosorbent assay). The animals were sacrificed after the neurological function was evaluated at 24 of reperfusion, and brain tissues were removed for microscopic examination of the pathological changes in cortex, for determination of percentage of cerebral infarct size (by TTC staining), for assessment of cell apoptosis and apoptosis rate in cortex (by TUNEL), and for determination of the expression of microglial biomarker Iba-1 and activated M1 microglia biomarker CD68 (by Western blot). Results:Compared with group Sham, the neurological function score, percentage cerebral infarct size, apoptosis rate in cortex, concentrations of TNF-α, IL-6 and IL-1β in the serum, and the expression of Iba-1 and CD68 were significantly increased in IR and SGB groups ( P<0.05). Compared with group IR, the neurological function score, percentage cerebral infarct size, apoptosis rate in cortex, concentrations of TNF-α, IL-6 and IL-1β in the serum, and the expression of Iba-1 and CD68 were significantly decreased in group SGB ( P<0.05), and the pathological changes of brain tissues were significantly attenuated in group SGB. Conclusion:The mechanism by which SGB reduces cerebral I/R injury is related to inhibiting activation of M1 microglia in rats.

ABSTRACT

Objective:To investigate the relationship between TP53 gene mutation and overall survival (OS) time of myelodysplastic syndrome (MDS).Methods:Databases, including PubMed, Cochrane Library and Embase were searched for relevant studies published up to 20 October, 2019. The corresponding hazard ratio ( HR) and their 95% confidence interval ( CI) for OS from multivariate Cox proportional hazard models were extracted. The combined HR with their 95% CI was calculated by using fixed or random effect models. Meta-analysis was performed by using Revman 5.3 software. Results:A total of 1 033 patients from 6 studies were enrolled. Meta-analysis results showed that OS time in TP53 gene mutation group was shorter than that in wild type group for patients with MDS ( HR = 2.16, 95% CI 1.52-3.07, P < 0.01). The prognostic risk for post-transplantation patients with MDS ( HR = 2.69, 95% CI 1.63-4.43, P < 0.01) was lower compared with that for patients treated by azacitidine( HR = 2.89, 95% CI 1.37-6.08, P = 0.005). Conclusion:TP53 gene mutation is a risk factor affecting OS of MDS patients.

ABSTRACT

OBJECTIVE@#To analyze the overall survival (OS) of elderly acute myeloid leukemia (AML) patients treated with oral arsenic-containing Qinghuang Powder (, QHP) or low-intensity chemotherapy (LIC).@*METHODS@#Forty-two elderly AML patients treated with intravenous or subcutaneous LIC (1 month for each course, at least 3 courses) or oral QHP (3 months for each course, at least 2 courses) were retrospectively analyzed from January 2015 to December 2017. The main endpoints of analysis were OS and 1-, 2-, 3-year OS rates of patients, respectively. And the adverse reactions induding bone marrow suppression, digestive tract discomfort and myocardia injury were observed.@*RESULTS@#Out of 42 elderly AML patients, 22 received LIC treatment and 20 received QHP treatment, according to patients' preference. There was no significant difference on OS between LIC and QHP patients (13.0 months vs. 13.5 months, >0.05). There was no significant difference on OS rates between LIC and QHP groups at 1 year (59.1% vs. 70.0%), 2 years (13.6% vs. 15%), and 3 years (4.6% vs. 5.0%, all >0.05). Furthermore, there was no significant difference of OS on prognosis stratification of performance status > 2 (12 months vs. 12 months), age> 75 year-old (12.0 months vs. 12.5 months), hematopoietic stem cell transplant comorbidity index >2 (12 months vs. 13 months), poor cytogenetics (12 months vs. 8 months), and diagnosis of secondary AML (10 months vs. 14 months) between LIC and QHP patients (>0.05).@*CONCLUSION@#QHP may be an alternative treatment for elderly AML patients refusing LIC therapy.

ABSTRACT

OBJECTIVE@#To analyze the consistency of gene mutation sites between bone marrow DNA (BM-tDNA) and perepheral plasma circulating tumor DNA (PP-ctDNA) in patients with myelodysplastic syndrome (MDS).@*METHODS@#The simultaneous sampled BM and PP from 19 patients (SBPP) was detected by NGS-127 gene panel, and the consistency of VAF between BM-tDNA and PP-ctDNA was analyzed. The peripheral blood cell tumor DNA (PC-tDNA) of 5 out of 19 patients was detected randomly, the consistency of VAF among PC-tDNA,BM-tDNA and PP-ctDNA was analyzed. The non simultaneous sampled BM and PP from 13 patients (NBPP) was detected, and the difference value of VAF between BM-tDNA and PP-ctDNA in SBPP and NBPP was analyzed.@*RESULTS@#The average concentration of PP-ctDNA in SBPP was 0.59 ng/µl and 0.604 ng/µl in NBPP. The median concentration of PP-ctDNA in SBPP and NBPP was 0.330 ng/µl and 0.338 ng/µl, respectively. The study showed a good consistency of VAF between BM-tDNA and PP-ctDNA in the SBPP (R=0.9693, P<0.05), and the consistency of VAF between BM-tDNA and PP-ctDNA in single base replacement (SNP) sites (R=0.9712) was better than that in insertion deletion (Indel) sites (R=0.6813). The results showed a good consistency of VAF between BM-tDNA and PP-ctDNA both in 12 patients before treatment (R=0.9325, P<0.05) and 5 patients (R=0.9875, P<0.05) after treatment. The results also showed that the VAF of PC-tDNA had a good consistency with the VAF of BM-tDNA (R=0.8783) and PP-ctDNA (R=0.8783) (P<0.05). The difference value of VAF between BM-tDNA and PP-ctDNA in SBPP was significantly lower than that in NBPP (P<0.05).@*CONCLUSION@#PP can replace BM as a biological sample for genes mutation detection in patients with MDS due to its stable concentration, high degree of consistency with bone marrow in clinical significant mutation sites and easy collection.

ABSTRACT

<p><b>BACKGROUND</b>People have more and more concerned about allitridum as studies have shown that taking more raw garlic associated with a lower risk for cancers of the alimentary system. In the present study, we tried to examine whether a large dose of allitridum and a microdose of selenium prevent gastric cancer.</p><p><b>METHODS</b>A double-blind intervention study was performed on the participants aged (35 - 74) years, who had matched at least one of the following criteria: (1) a medical history of stomach disorder, (2) a family history of tumour, or (3) smoking and/or alcohol consumption. A total of 2,526 and 2,507 persons were randomly enrolled into intervention group and control group respectively from 288 natural villages of seven communities in Qixia County, Shandong Province, China. Each person of the intervention group orally took 200 mg synthetic allitridum every day and 100 microg selenium every other day for one month of each year during November 1989 to December 1991. At the same time, people in control group were given 2 placebo capsules containing corn oid with the identical appearance to that in the intervention group.</p><p><b>RESULTS</b>For all subjects the large dose of allitridum was accepted and no harmful side effects were found during the study. In the first follow-up five years (1992 - 1997) after stopping the intervention, the morbidity rates of malignant tumours in the intervention group declined by 22%, in contrast to the control group, declined by 47.3%. After adjusting for age, gender, and other potential confounders, relative risks (RRs) for all tumours and gastric cancer of the whole population were 0.67 (95% CL: 0.43 - 1.03) and 0.48 (95% CL: 0.21 - 1.06), respectively, and for male group they were 0.51 (95% CL: 0.30 - 0.85) and 0.36 (95% CL: 0.14 - 0.92), respectively. No signigicantly protective effect was found for the female subgroup.</p><p><b>CONCLUSION</b>The present study proves that large doses of allitridum and microdorse of selenium may effectively prevent gastric cancer, especially in men.</p>
