ABSTRACT

Abstract@#Excessive intake of sugar-sweetened beverages among children and adolescents could increase the risks of adverse health outcomes, including dental caries and obesity. This study reviewed the consumption of sugar-sweetened beverages among children and adolescents in China and the international strategies to reduce the consumption of sugar-sweetened beverage. The aim of the study was to provide a reference for the introduction of relevant policies to control the intake of sugar-sweetened beverages in children and adolescents in China. In summary, measures including a tax on sugar-sweetened beverages, implementing front-of-pack labelling system, restricting marketing and publicity and education have been adopted to control the consumption of sugar-sweetened beverages in some countries, while public publicity and education have been adopted in China. It is suggested that comprehensive policies and measures should be adopted to control the intake of sugar-sweetened beverage among Chinese children.

ABSTRACT

Objective To investigate the effects of upadacitinib on the polarization and inflammation of BV2 microglia after oxygen glucose deprivation/recovery (OGD/R) and to explore its mechanism of action. Methods The experiment was divided into 3 groups: control group, OGD group and upadacitinib treatment group. After BV2 cells were treated with OGD/R, MTT was used to detect cell survival rate. Wound scratch assay was used to detect the cell migration ability. qPCR was used to detect mRNA levels of M1-type polarization markers (CD11b, CD32, iNOS) and M2-type polarization markers (Arg-1, IL-10, CD206) of BV2 cells. ELISA was used to detect the levels of IL-1β, IL-6, and TNF-α in the culture medium. Western blot was used to detect the expression levels of JAK1/STAT6 pathway-related proteins. Results Upadacitinib increased the survival of BV2 cells after OGD/R (P<0.05), reduced the polarization of BV2 cells to M1 type (P<0.05). Upadacitinib significantly decreased the migration ability of BV2 cells induced by OGD/R (P<0.05), reduced the inflammatory factors secreted by BV2 cells induced by OGD/R: IL-1β, IL-6, TNF-α (P<0.05). Upadacitinib increased the survival rate of co-cultured PC12 cells (P<0.05). Upadacitinib significantly inhibited the expression levels of p-JAK1 and p-STAT6 proteins in BV2 cells activated by OGD/R induction (P<0.05). Conclusion Upadacitinib decreases polarization of BV2 induced by OGD/R to M1 type and reduces inflammation, which is related to JAK1/STAT6 pathway.

ABSTRACT

Diabetic peripheral neuropathy(DPN),a chronic diabetic microvascular complication with a high incidence among diabetic patients,increases the risk of diabetic foot and amputation.Many methods are available for screening and evaluating DPN,including traditional 10 g monofilament,tuning fork and vibration perception,and tendon reflex tests,which should be combined with some nerve function score systems to improve the detection rate and accuracy for DPN.In recent years,a number of noninvasive new techniques have been developed for the evaluation of nerve injury,such as corneal confocal microscopy,quantitative sensory testing,current perception threshold test,sympathetic sudomotor function evaluation,and quantitative detection of skin advanced glycation end products.This paper reviews these noninvasive methods for screening and evaluating DPN to help clinicians detect and focus on DPN early.

ABSTRACT

Objective To compare the differentially expressed proteins between cypermethrin-resistant and -sensitive Culex pipiens pallens, so as to unravel the mechanism underlying the resistance to cypermethrin in Cx. p. pallens. Methods A quantitative proteomic analysis was performed among cypermethrin-sensitive and -resistant isolates of Cx. p. pallens using isobaric tags for relative and absolute quantification (iTRAQ) labeling coupled with liquid chromatography with tandem mass spectrometry (LC-MS/MS). Results A total of 164 differentially expressed proteins were identified between cypermethrin-sensitive and -resistant isolates of Cx. p. pallens, including 54 up-regulated proteins and 110 down-regulated proteins. A large number of cuticular proteins, larval cuticular proteins, pupal cuticular proteins and cuticular structural constituent proteins, which are associated with cytoskeletal structure and components, were differentially expressed between cypermethrin-sensitive and -resistant isolates of Cx. p. pallens. Thirteen proteins, which were involved in energy production and conversion, translation, ribosomal structure and biogenesis, lipid transport and metabolism, post-translational modification, protein turnover, chaperones, cytoskeleton and intracellular transportation, were validated to be differentially expressed between cypermethrin-sensitive and -resistant isolates of Cx. p. pallens, which may serve as potential markers of cypermethrin resistance. Conclusion Multiple insecticide resistance mechanisms contribute to the resistance to cypermethrin in Cx. p. pallens, including cuticular resistance and metabolic resistance, and the cuticular protein genes and cytochrome P450 enzymes may play an important role in the resistance of Cx. p. pallens to cypermethrin.

ABSTRACT

Objective:To analyze the composition differences of intestinal microbiota in patients with colon cancer and rectal cancer.Methods:The fecal samples of 72 patients in the Second Affiliated Hospital of Harbin Medical University from July 2018 to January 2019 were collected, and they were divided into colon cancer group and rectal cancer group, 36 cases in each group. DNA from fecal samples was extracted, and then high-throughput sequencing was performed on DNA. Bioinformatics was used to analyze the diversity and composition differences of intestinal microbiota between the two groups, and the potential cancer-promoting mechanisms of the differential flora were also discussed.Results:From high-throughput sequencing, 2 356 560 original sequences and 32 730 high-quality sequences were obtained from 72 samples. The average length of the sample sequence was mainly in the interval of 401-460 bp. And 1 409 operational taxonomic units (OTU) were acquired after OTU species taxonomy annotation of all the sequences. Alpha diversity analysis showed that Shannon index of the rectal cancer group and the colon cancer group was 2.61±0.56 and 2.43±0.67, respectively, and the difference was statistically significant ( t = 1.229, P = 0.223); Simpson index of the rectal cancer group and the colon cancer group was 0.17±0.09 and 0.21±0.16, respectively, and the difference was statistically significant ( t = 1.449, P = 0.151). Differences analysis of both groups and linear discriminant analysis (LDA) showed at the phylum level, Firmicutes were more abundant in the intestine of patients with rectal cancer (LDA = 4.67, P = 0.014), while Proteobacteria were more abundant in the gut of colon cancer patients (LDA = 4.49, P = 0.042). From the perspective of class level, the abundance of Gammaproteobacteria was higher in the intestine of patients with colon cancer (LDA = 4.50, P = 0.033), while the abundance of Erysipelotrichia was higher in the intestine of patients with rectal cancer (LDA = 3.50, P = 0.035). At the order level, the abundance of Erysipelotrichales was higher in the intestine of patients with rectal cancer (LDA = 3.50, P = 0.035); at the family level, the abundance of Porphyromonadaceae was higher in the intestine of patients with rectal cancer (LDA = 3.97, P = 0.033). Conclusion:The compositions of intestinal microbiota in patients with colon cancer and rectal cancer are significantly different, indicating that the different floras may contribute to the progression of colon cancer and rectal cancer.

ABSTRACT

Objective:To analyze phylogenetic structure and molecular characteristics of H5N6 avian influenza virus (AIVs) isolated from live poultry market (LPM).Methods:Oropharyngeal and cloacal swabs from poultry, and environmental samples were collected from LPM in Urumqi in December 2018, AIVs were isolated and identified by inoculation of chicken embryo, hemagglutination test and RT-PCR, the viral whole genome was amplified with the universal primers of influenza A virus, and then sequenced, pairwise sequence alignments, phylogenetic and molecular characteristics analysis were performed by BLAST, Clustal W, MEGA-X and DNAStar software.Results:Six strains of H5N6 AIVs were isolated from poultry samples, the identity between the viral genes was high (99.4%-100.0%), so the isolates were the same source. BLAST analysis revealed that the viral NP sequence had the highest identity (99.7%) with H5N6 AIVs isolated from poultry in Suzhou, while the sequence of the remaining 7 viral genes had the highest identity (99.0%-100.0%) with H5N6 AIVs isolated from environment in Guangdong during 2017 to 2018. Phylogenetic analysis showed that the viral HA belonged to Clade 2.3.4.4C, and the viral HA, NA, PB1, PA, NP, and MP were all clustered together with H5N6 AIVs isolated from mink in Eastern China in 2018, while the PB2 and NS were clustered together with H5N6 AIVs isolated from environment in Guangdong from 2017 to 2018. The HA cleavage site contained multiple basic amino acid residues, which was highly pathogenic AIVs (HPAIVs). S137A and T160A mutations of HA could increase binding to human-type receptor SAα2, 6-Gal. Additionally, the viral multiple mutations, including 59-69 deletion in NA, the L89V, G309D, R477G, I495V, I504V, D391E, and A661E in PB2, as well as the P42S, D92E, and 80-84 deletion in NS1, could enhance the viral virulence and pathogenicity to mammals. Conclusions:The 6 strains of H5N6 HPAIVs isolated from LPM have relatively close genetic relationship with H5N6 AIVs isolated from mink in Eastern China and environment in Guangdong during 2017 to 2018, the viral multiple mutations could increase its pathogenicity to mammals, which could pose a potential risk to public health.

ABSTRACT

Objective:To investigate the effect of hemoglobin (Hb) volatility on cardiovascular prognosis in peritoneal dialysis (PD) patients.Methods:Retrospective cohort study was designed. Patients undergoing stable PD for more than 3 months and followed up regularly for at least 1 year were enrolled from May 1, 2013 to October 31, 2014 in the General Hospital of Ningxia Medical University. According to the Hb variation based on the mean changes in Hb standard deviation at 1 month, 3 months, 6 months, 12 months over baseline Hb, all patients were divided into low volatility group (≤10 g/L), moderate volatility group (>10-20 g/L) and high volatility group (>20 g/L), and baseline information were compared among these groups. Kaplan-Meier survival analysis and Cox regression equation were used to analyze the relationship between Hb variation and cardiovascular mortality and all-cause mortality. Besides, the patients were divided into qualified group (Hb≥110 g/L) and substandard group (Hb<110 g/L) by the Hb level at the study endpoint (cardiovascular death and all-cause death) according to KDIGO guidelines and relevant literature. Cox regression analysis was used to analyze the relationship between Hb variation and cardiovascular death in qualified group or substandard group. Multivariate linear regression analysis was used to analyze the related factors of Hb fluctuation in PD patients.Results:A total of 267 patients were enrolled. There were 160 males (59.93%) in this study. The age was (52.66±13.72) years old, and the median dialysis age was 37(21, 61) months. The patients' baseline Hb (before dialysis) was (80.16±14.89) g/L and at the end of the study Hb was (105.34±22.08) g/L. Body mass index and baseline Hb levels in the high volatility group were lower than those in low volatility group and moderate volatility group (all P<0.05). Both moderate and high volatility groups had lower estimated glomerular filtration rate than that in low volatility group, and high volatility group had higher urea nitrogen level than that in low volatility group (all P<0.05). The amount of erythropoietin usage in the high volatility group was higher than that in moderate volatility group ( P<0.05). The Kaplan-Meier survival analysis results showed that there was no significant difference in survival rate for all-cause death (Log-rank χ2=0.735, P=0.693) and cardiovascular death (Log-rank χ2=2.961, P=0.228) in different Hb volatility groups. Cox regression analysis showed that after adjusting for age, sex, serum creatinine, and blood albumin, higher Hb volatility was associated with a lower risk of cardiovascular death ( HR=0.972, 95% CI 0.947-0.999, P=0.040). After adjusting for related confounding factors, higher Hb volatility was still a protective factor for cardiovascular death in the substandard group ( HR=0.946, 95% CI 0.903-0.992, P=0.022), but there was no significant correlation between Hb fluctuation and all-cause death. Multivariate linear regression analysis results showed that the fluctuation level of Hb was positively correlated with Kt/V ( B=4.682, 95% CI 2.480-6.884, P<0.001) and erythropoietin dosages ( B=0.001, 95% CI 0-0.001, P=0.003), and negatively correlated with baseline Hb ( B=-0.554, 95% CI -0.651--0.457, P<0.001). Conclusions:High Hb variability is a protective factor for cardiovascular death in PD patients with lower Hb level (substandard Hb). Adopting a reasonable program to correct anemia timely to reach the standard level has a greater impact on reducing risk of cardiovascular death in PD patients than Hb variation in anemia treatment.

ABSTRACT

Objective:To assess the value of CD4 + and CD8 + T-lymphocyte counts for the diagnostic classification and prognosis of coronavirus disease 2019 (COVID-19). Methods:A total of 95 COVID-19 adult patients admitted to Shanghai Public Health Clinical Center, Fudan University from January to March 2020 were recruited. The CD4 + and CD8 + T-lymphocyte counts among ordinary, severe and critical patients, as well among the cured, improved, unimproved and death patients were compared. The area under receiver operating characteristic curve (AUROC) was used to evaluate the value of CD4 + and CD8 + T-lymphocyte counts for the clinical diagnosis and prognosis of COVID-19. The comparison among groups was performed by Mann-Whitney U test. Results:A total of 95 COVID-19 cases including 68 common, 11 severe and 16 critical cases were enrolled. The counts of CD4 + and CD8 + T-lymphocyte of patients in common, severe and critical groups were 419 (309, 612), 267 (212, 540), 141 (77, 201)/μL, and 238 (153, 375), 128 (96, 172), 92 (51, 144)/μL, respectively, with significant differences ( Z=24.322 and 15.956, respectively, both P<0.01). The counts of CD4 + and CD8 + T-lymphocyte of the death, unimproved, improved, and cured patients were 149 (143, 349), 315 (116, 414), 344 (294, 426), 745 (611, 966)/μL, and 106 (43, 501), 176(67, 279), 194(188, 432), 429(276, 564)/μL, respectively, with significant differences ( Z=36.083 and 16.658, respectively, both P<0.01). The optimal cut-off point of CD4 + T-lymphocyte counts was 237/μL for critical COVID-19 with AUROC 0.911 (95% confidence interval ( CI) 0.833-0.989, P<0.01), with the sensitivity of 86.1% and specificity of 87.5%. For predicting severe and critical cases, the optimal cut-off point of CD4 + T-lymphocyte counts was 405/μL with AUROC 0.863 (95% CI 0.727-0.999, P=0.001), with the sensitivity of 78.6% and specificity of 74.6%. Conclusions:The conditions of patients with COVID-19 are aggravated with CD4 + and CD8 + T-lymphocyte counts decreasing. CD4 + T-lymphocyte counts may be an indicator for diagnostic classification of COVID-19 and prognostic indicator for severe and critical patients.

ABSTRACT

Objective:To investigate the characteristics of the sleep quality and health-related quality of life (HRQoL), and analyze the different effects of sleep quality on HRQoL among young and middle-aged people.Methods:A cross-sectional study recruited 1 976 participants.All participants completed a self-designed questionnaire for the adults' general condition, the Pittsburgh sleep quality index (PSQI) and Short-Form health survey (SF-36). All participants were divided into 3 age groups: 18-29-year-old group( n=1 148), 30-44-year-old group( n=586) and 45-59-year-old group ( n=242). SPSS 23.0 software was used for statistical analysis.Chi-square test was used to analyze the general characteristics of the three age groups.Non-parametric test was used to analyze the scores of the three age groups in different dimensions of sleep quality. One-way ANOVA was used to analyze the mean scores of the three age groups in different dimensions of HRQoL. Stepwise regression analysis was used to analyze the effect of sleep quality on HRQoL among the three groups after control the confounding factors such as marital status, education, smoking, drinking and exercise habits and past medical history. Results:In terms of sleep quality, the total PSQI scores of 18-29-year-old, 30-44-year-old and 45-59-year-old groups(4(2, 6), 4(2, 6), 4(2, 6)) showed statistically significant differences ( Z=10.951, P=0.004). In terms of HRQoL, there were statistically significant differences in physical component summary scores (18-29-year-old: 82.51±12.62, 30-44-year-old: 80.72±13.63, 45-59-year-old: 82.04±13.07, F=3.667, P=0.026) and mental component summary scores(18-29-year-old: 76.09±15.46, 30-44-year-old: 77.20±16.14, 45-59-year-old: 81.82±14.14, F=13.649, P<0.001) among young and middle-aged people in different age groups.Regression analysis found that daytime dysfunction was an independent influencing factor for HRQoL in young and middle-aged population ( β=-0.308--0.425, all P<0.01). Sleep disorders significantly decreased Physical Component Summary of HRQoL in young-aged people ( β=-0.127--0.215, all P<0.01). The use of hypnotic drugs significantly reduced the scores in the physiological field in the young adults aged 30-44 ( β=-0.076, P<0.05). The duration of sleep significantly decreased the scores in the mental domain of young adults aged 30-44 ( β=-0.112, P<0.01). Subjective sleep quality was an independent factor that significantly decreased HRQoL in young adults aged 18-29 and 30-44 years ( β=-0.089--0.169, all P<0.01). Conclusion:Sleep quality and HRQoL of young and middle-aged people in different age groups show different characteristics.The effect of sleep quality on HRQoL is different among people in different ages.Taking targeted interventions for people of different ages to improve the sleep quality may be an effective way to improve their HRQoL.

ABSTRACT

Objective:To explore the feasibility and precautions of laparoscopic pyeloplasty for children with hydronephrosis combined with renal trauma.Methods:The clinical data of 6 cases with hydronephrosis and renal trauma admitted to the Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from August 2016 to August 2019, aged from 5 to 11 years old (average age 7 years old) were reviewed.These patients had suffered renal trauma for 1 to 4 days.All patients had the symptoms of pain in the affected kidney, and 4 patients had hematuria.The renal pelvis diameter of all patients was more than 25 mm.The patients underwent laparoscopic pyeloplasty and renal rupture repairment, with the ureteral stent, perirenal drainage tube and catheter placed inside the body during the operation.Results:All operations were completed successfully without any blood transfusion and open surgery.Intrao-perative time was from 2.5 to 3.5 hours.Two cases had renal parenchymal contusion in the front lower pole of kidneys and 4 cases in the lateral lower pole.Five cases had renal cortex and pelvis rupture, and 1 case had renal cortical fracture and subcapsular hematoncus.After the operation, the perinephric drainage tube was pulled out in 3 to 5 days, the catheter was pulled out in 7 to 10 days, and the ureteral stent was removed in 6 to 8 weeks.All children recovered well and hydronephrosis was ameliorated.The glomerular filtration rates and fractional renal function were all improved.Conclusions:One stage laparoscopic pyeloplasty is safe and effective for the treatment of hydronephrosis with renal trauma in children.Renal trauma in children usually occurs at the lower pole of the kidney.Early operation is needed if hydronephrosis is aggravated and symptoms are not relieved after the trauma.Intraoperative impairment of renal parenchymal rupture can be conducted.For intraoperative bleeding in grade 3 renal injury, renal parenchyma suturation and removal of necrotic renal tissue should be adopted to arrest bleeding.

ABSTRACT

Objective: To research the effect of matrine on the proliferation and migration of HepG2 cells through extracellular signal-regulated kinase 1/2 (ERK1/2) signaling pathway. Methods: HepG2 cell was selected and divided into blank control group, experimental group (matrine 1, 2, and 4 mg/mL), and positive control group (PD98059, ERK1/2 inhibitor). MTT measure was used to detect the effective time and concentration which matrine inhibits HepG2 cells. After 24 h, the effect of effective concentration of matrine on the of morphological changing HepG2 cells was observed. The invasion ability was assayed by transwell method, the expression of ERK1/2 and pERK1/2 were detected through Western blot, and reverse transcription polymerase chain reaction was used to test the expression level of ERK1/2 mRNA. Results: With the increase of matrine concentration, the number of adherent HepG2 cells gradually decreased, the morphologic changes gradually became spherical, some cell morphology was incomplete, and even cell fragments appeared. The proliferation and invasion ability of HepG2 cells decreased. The expression of ERK1/2, pERK1/2, and ERK1/2 mRNA downregulated with the increase of matrine concentration (P < 0.05). Conclusion: Matrine inhibits the proliferation and migration of HepG2 cells by downregulating the ERK1/2 signaling pathway.

ABSTRACT

Ischemic stroke is one of the leading causes of death worldwide. In the post-stroke stage, cardiac dysfunction is common and is known as the brain-heart interaction. Diabetes mellitus worsens the post-stroke outcome. Stroke-induced systemic inflammation is the major causative factor for the sequential complications, but the mechanism underlying the brain-heart interaction in diabetes has not been clarified. The NLRP3 (NLR pyrin domain-containing 3) inflammasome, an important component of the inflammation after stroke, is mainly activated in M1-polarized macrophages. In this study, we found that the cardiac dysfunction induced by ischemic stroke is more severe in a mouse model of type 2 diabetes. Meanwhile, M1-polarized macrophage infiltration and NLRP3 inflammasome activation increased in the cardiac ventricle after diabetic stroke. Importantly, the NLRP3 inflammasome inhibitor CY-09 restored cardiac function, indicating that the M1-polarized macrophage-NLRP3 inflammasome activation is a pathway underlying the brain-heart interaction after diabetic stroke.

OBJECTIVE@#To explore the genetic basis for a child with supravalvular aortic stenosis.@*METHODS@#The child and his parents were subjected to conventional G-banding karyotyping, array comparative genomic hybridization (aCGH) and multiplex ligation-dependent probe amplification (MLPA) analysis.@*RESULTS@#No karyotypic abnormality was detected in the child and his parents. aCGH has identified a de novo 278 kb deletion encompassing the ELN gene in 7q11.23, which overlapped with the critical region of Williams-Beuren syndrome (WBS). MLPA has confirmed above findings.@*CONCLUSION@#The proband was diagnosed with atypical WBS. Deletion of the ELN gene may predispose to supravalvular aortic stenosis in the proband.

ABSTRACT

Nuclear protein of the testis midline carcinoma (NMC) is a rare malignant tumor that is mostly located in the upper trachea,mediastinal midline,and paravertebral midline,and few literature has described the imaging features of NMC in the nasal cavity and paranasal sinuses. In this article we summarize the clinical,radiologic,and pathologic data of one case of pathologically confirmed NMC in the nasal cavity and paranasal sinus by focusing on its CT and magnetic resonance imaging features.

ABSTRACT

BACKGROUND@#Transcranial alternating current stimulation (tACS) offers a new approach for adult patients with major depressive disorder (MDD). The study is to evaluate the efficacy and safety of tACS treating MDD.@*METHODS@#This is an 8-week, double-blind, randomized, placebo-controlled study. Ninety-two drug-naive patients with MDD aged 18 to 65 years will receive 20 daily 40-min, 77.5-Hz, 15-mA sessions of active or sham tACS targeting the forehead and both mastoid areas on weekdays for 4 consecutive weeks (week 4), following a 4-week observation period (week 8). The primary outcome is the remission rate defined as the 17-item Hamilton depression rating scale (HDRS-17) score ≤7 at week 8. Secondary outcomes are the rates of response at weeks 4 and 8 and rate of remission at week 4 based on HDRS-17, the proportion of participants having improvement in the clinical global impression-improvement, the change in HDRS-17 score (range, 0-52, with higher scores indicating more depression) over the study, and variations of brain imaging and neurocognition from baseline to week 4. Safety will be assessed by vital signs at weeks 4 and 8, and adverse events will be collected during the entire study.@*DISCUSSION@#The tACS applied in this trial may have treatment effects on MDD with minimal side effects.@*TRIAL REGISTRATION@#Chinese Clinical Trial Registry, ChiCTR1800016479; http://www.chictr.org.cn/showproj.aspx?proj=22048.
