ABSTRACT

Objective To investigate the predictive value of serum interleukin(IL)-34 and soluble uroki-nase-type plasminogen activator receptor(suPAR)for poor prognosis in children with asthma.Methods A total of 184 children with asthma admitted to the hospital from January 2020 to December 2021 were enrolled in the study as the asthma group,and 184 healthy children who underwent physical examination in the hospital during the same period were enrolled as the healthy group.Enzyme-linked immunosorbent assay(ELISA)was used to measure the serum levels of IL-34 and suPAR in the two groups.The children in the asthma group were followed up for 1 year,and the prognosis was evaluated using the Asthma Control Test(ACT)score ta-ble.Logistic regression was used to analyze the influencing factors of poor prognosis in children with asthma.The receiver operating characteristic(ROC)curve was used to analyze the predictive value of serum IL-34 and suPAR levels for the prognosis of children with asthma.Results The asthma group had significantly higher serum levels of IL-34 and suPAR than the healthy group(P<0.05).The incidence of poor prognosis was 22.65%(40/181).Compared with the good prognosis group,the poor prognosis group had significantly high-er proportion of children with preterm birth,passive smoking,a family history of asthma,a history of respira-tory infection,pet rearing,severe disease and serum levels of IL-34 and suPAR(P<0.05),and a significantly lower proportion of children with breast feeding(P<0.05).The multivariate Logistic regression analysis showed that preterm birth,family history of asthma,severe disease,and high levels of IL-34 and suPAR were risk factors for poor prognosis in children with asthma(P<0.05),while breastfeeding was a protective factor(P<0.05).The area under the ROC curve(AUC)of the combination of serum IL-34 and suPAR for predic-ting poor prognosis in children with asthma was 0.896(95%CI:0.842-0.936),which was greater than the AUC of IL-34 alone(Z=2.636,P=0.008)and the AUC of suPAR alone(Z=2.430,P=0.015).Conclusion Children with asthma have elevated serum levels of IL-34 and suPAR,both of which are risk fac-tors for poor prognosis in children with asthma.Both of them have a good predictive value for the prognosis of children with asthma,and the combination of the two has higher predictive efficiency.

ABSTRACT

BACKGROUND:Fibronectin type Ⅲ domain-containing protein 5(FNDC5)is a muscle factor that can regulate glucose and lipid metabolism,and exert anti-inflammatory,anti-oxidative effects and improvement in insulin resistance.Moreover,FNDC5 could control various cell pyroptosis. OBJECTIVE:To explore the effect and potential mechanism of FNDC5 on macrophage pyroptosis. METHODS:(1)After completing the construction of the lentivirus virus overexpressing FNDC5 or silencing FNDC5,the THP-1 cells were transfected with the lentivirus vector.The result of transfection was detected by the expression of green fluorescence,qPCR,and western blot assay.(2)Phorbol ester induced THP-1 cells to differentiate into macrophages.Oxidized low-density lipoprotein(ox-LDL)was added to induce the cell pyroptosis model.There were six groups,i.e.,NC group,ox-LDL group,ox-LDL+MOCK1 group,ox-LDL+Ov-FNDC5 group,ox-LDL+MOCK2 group,and ox-LDL+shFNDC5 group.(3)The level of cell pyroptosis was evaluated by Hoechst 33342/propidium iodide fluorescence double staining and lactate dehydrogenase release assay.The expression levels of related molecules in THP-1 cells were analyzed by qPCR and western blot assay.The interleukin-18 and interleukin-1β in cell supernatant were detected by ELISA. RESULTS AND CONCLUSION:Compared with the ox-LDL+MOCK1 group,overexpression of FNDC5 significantly reduced the pyroptosis rate of macrophages and the release levels of lactate dehydrogenase,interleukin-1β and interleukin-18,significantly inhibited the mRNA expression of NF-κB p65,NF-κB p50,NLRP3,ASC,Caspase-1,and GSDMD,and significantly inhibited the protein expression of NF-κB p65,NF-κB p50,NLRP3,ASC,cleaved Caspase-1 and GSDMD-N.Compared with the ox-LDL+MOCK2 group,the silence of FNDC5 showed the opposite result.These findings suggest that FNDC5 attenuates pyroptosis in macrophages by inhibiting the NF-κB/NLRP3 pathway.

ABSTRACT

OBJECTIVE To evaluate the effects of ABCB1 genotypes on the efficacy and safety of taxanes in the treatment of breast cancer. METHODS By searching Embase,the Cochrane Library, PubMed, CNKI, and Wanfang databases, cohort studies and case-control studies about taxanes in the treatment of breast cancer were collected from the establishment of the database to July 2023. After screeningliterature, extracting data and evaluating quality, meta-analysis was performed by using RevMan 5.3 software. RESULTS A total of 11 studies were included, involving 1 321 patients. There was no correlation between the three genotypes and effective rate, the incidence of myelosuppression, the incidence of neurotoxicity (except for the allele and recessive model of ABCB1 C1236T), and the incidence of hypersensitivity reactions (P>0.05). The subgroup analysis showed that there was a correlation between ABCB1 C1236T dominant model and effective rate when using anthracyclines+5-fluorouracil+cyclophosphamide+taxanes (P<0.05), there was a correlation between ABCB1 C3435T recessive model and effective rate when using taxanes+trastuzumab (P<0.05). ABCB1 C1236T allele model and recessive model were correlated with sample size ≥100 and using cyclophosphamide+epirubicin+5- fluorouracil+paclitaxel or cyclophosphamide+epirubicin+paclitaxel+trastuzumab or cyclophosphamide+epirubicin+5-fluorouracil+ trastuzumab+paclitaxel regimens; recessive model with sample size <100 and the African region were correlated with the incidence of peripheral neuropathy; recessive model was correlated with cutaneous adverse reactions (P<0.05). ABCB1 C3435T recessive model was correlated with the incidence of reduced neutrophil count with sample size ≥100; the incidence of white blood cell count reduction with sample size <100 and using docetaxel+epirubicin+cyclophosphamide was correlated with both the allele model and the dominant model; the incidence of infections was correlated with the dominant model (P<0.05). The incidence of neutrophil count reduction with the sample size <100 was correlated with allele model of ABCB1 G2677T/A; the incidence of edema with sample size ≥100 was correlated with allele model and recessive model; the incidence of infection was correlated with allele model and dominant model, especially in patients with neutrophil count complicated with fever (P<0.05). CONCLUSIONS ABCB1 genotypes are not correlated with effective rate of taxanes in the treatment of breast cancer, but ABCB1 C3435T genotype is associated with decreased neutrophil counts, decreased white blood cell counts and infections; ABCB1 C1236T genotype is associated with neurotoxicity and cutaneous adverse reactions; ABCB1 G2677T/A genotype is associated with decreased neutrophil counts, infections, and edema.

The Questionnaire of Quality Monitoring Indicators for Blood Collection and Supply Process was distributed to 17 blood banks in Shandong, which clarified the definition and calculation formula of indicators. The quality monitoring indicator data from January to December 2022 in each blood bank were collected, and 20 quality control indicators data were analyzed by SPSS25.0 software. 【Results】 The average pass rate of key equipment monitoring, environment monitoring, key material monitoring, and blood testing item monitoring of 17 blood banks were 99.47%, 99.51%, 99.95% and 98.99%, respectively. Significant difference was noticed in the pass rate of environment monitoring among blood banks of varied scales(P<0.05), and the Pearson correlation coefficient (r) between the total number of blood quality testing items and the total amount of blood component preparation was 0.645 (P<0.05). The average discarding rates of blood testing or non-blood testing were 1.14% and 3.36% respectively, showing significant difference among blood banks of varied scales (P<0.05). The average discarding rate of lipemic blood was 3.07%, which had a positive correlation with the discarding rate of non testing (r=0.981 3, P<0.05). There was a statistically significant difference in the discarding rate of lipemic blood between blood banks with lipemic blood control measures and those without (P<0.05). The average discarding rate of abnormal color, non-standard volume, blood bag damage, hemolysis, blood protein precipitation and blood clotting were 0.20%, 0.14%, 0.06%, 0.06%, 0.02% and 0.02% respectively, showing statistically significant differences among large, medium and small blood banks(P<0.05).The average discarding rates of expired blood, other factors, confidential unit exclusion and unqualified samples were 0.02%, 0.05%, 0.003% and 0.004%, respectively. The discarding rate of blood with air bubbles was 0.015%, while that of blood with foreign body and unqualified label were 0. 【Conclusion】 The quality control indicator system of blood banks in Shandong can monitor weak points in process management, with good applicability, feasibility, and effectiveness.

ABSTRACT

Non-syndromic oral cleft (NSOC), a common birth defect, remains to be a critical public health problem in China. In the context of adjustment of childbearing policy for two times in China and the increase of pregnancy at older childbearing age, NSOC risk prediction will provide evidence for high-risk population identification and prenatal counseling. Genome-wide association study and second generation sequencing have identified multiple loci associated with NSOC, facilitating the development of genetic risk prediction of NSOC. Despite the marked progress, risk prediction models of NSOC still faces multiple challenges. This paper summarizes the recent progress in research of NSOC risk prediction models based on the results of extensive literature retrieval to provide some insights for the model development regarding research design, variable selection, model-build strategy and evaluation methods.

ABSTRACT

Objective: To investigate the safety and efficacy of embedding the stump of gastroduodenal artery between the left lateral lobe of the liver and the left caudate lobe to prevent bleeding after laparoscopic pancreaticoduodenectomy. Methods: The clinical data of 41 patients who underwent laparoscopic pancreaticoduodenectomy at the second Hospital of Hebei Medical University from October 2021 to April 2022 were analyzed retrospectively.There were 27 males and 14 females, aged (63.0±9.2)years (range: 48 to 78 years), and the body mass index was (24.1±3.2)kg/m2 (range: 15.4 to 31.6 kg/m2). After routine laparoscopic pancreaticoduodenectomy, the stump of gastroduodenal artery was embedded between the left lateral lobe and the left caudate lobe of the liver, and the hepatic parenchyma of the left lateral lobe and the left caudate lobe were sutured with absorbable sutures.The occurrence and recovery of postoperative complications (pancreatic fistula, biliary fistula, postoperative abdominal bleeding, abdominal infection, liver abscess) were observed. Results: All the operations of 41 patients were completed successfully.The operation time was (277.5±52.0) minutes (range: 192 to 360 minutes). The entrapment time of gastroduodenal artery stump was (3.1±0.6) minutes (range: 2.3 to 4.2 minutes), and the intraoperative blood loss (M(IQR)) was 300 (200) ml (range: 50 to 800 ml).The results of ultrasound examination of hepatic artery on the first day after operation showed that the blood flows of hepatic artery were unobstructed.Postoperative pancreatic fistula occurred in 3 cases, including grade B pancreatic fistula in 2 cases (1 case with abdominal infection) and biochemical leakage in 1 case. Three patients with pancreatic fistula were discharged successfully after continuous abdominal drainage. There was no biliary fistula, abdominal bleeding, abdominal infection, liver abscess or postoperative liver dysfunction. Conclusion: The encasement of the gastroduodenal artery stump by the left outer and left caudate lobes of the liver may be an effective way to prevent bleeding from the rupture of the gastroduodenal artery stump after laparoscopic pancreatoduodenectomy, which is easy and safe to perform.

ABSTRACT

Objective: To investigate the association between screen exposure and language skills in children aged 2-5 years. Methods: There were 299 children aged 2-5 years, recruited by convenience sampling from those who visited the Center of Children's Healthcare, Children's Hospital, Capital Institute of Pediatrics for routine physical examination from November 2020 to November 2021. Their development status were evaluated by the children neuropsychological and behavioral scale (revision 2016). A self-designed questionnaire for parents was conducted to collect demographic and socioeconomic information and screen exposure characteristics (time and quality). One-way ANOVA and independent sample t test were applied to compare the differences in language development quotient of children with different screen exposure time and quality. Multiple linear regression was used to analyze the correlation between screen exposure time and quality with language developmental quotient. Multivariate Logistic regression was used to analyze the risk of language underdevelopment in children with different screen exposure time and quality. Results: Among 299 children, 184 (61.5%) were boys and 115 (38.5%) were girls, with the age of (3.9±1.1) years. The number of children with daily screen time <60, 60-120 and>120 min was 163 children (54.5%), 86 children (28.8%) and 50 children (16.7%), respectively, with the language development quotients of 94±13, 90±13, 84±14, respectively, demonstrating a statistically significant difference (F=8.92, P<0.001). Logistic regression analysis revealed that screen exposure time of 60-120 and >120 min per day were both risk factors for children's language developmental quotients (OR=2.28, 95%CI 1.00-5.17, P=0.043; OR=3.96, 95%CI 1.86-9.17, P<0.001), and co-viewing and exposure to educational programs were both protective factors for children's language developmental quotients (OR=0.48, 95%CI 0.25-0.91, P=0.024, OR=0.36, 95%CI 0.19-0.70, P=0.003). Conclusions: Excessive exposure screen time and inappropriate screen exposure habits are associated with children's poorer language development. Screen exposure time should be limited and screen use should be rational to promote children's language skills.

ABSTRACT

Objective: To report the perioperative management and robot-assisted minimally invasive surgery results of one case with malignant tumor of anal canal combined with severe abdominal distention. Methods: A 66-year-old male suffer from adenocarcinoma of anal canal (T3N0M0) with megacolon, megabladder and scoliosis. The extreme distention of the colon and bladder result in severe abdominal distention. The left diaphragm moved up markedly and the heart was moved to the right side of the thoracic cavity. Moreover, there was also anal stenosis with incomplete intestinal obstruction. Preoperative preparation: fluid diet, intravenous nutrition and repeated enema to void feces and gas in the large intestine 1 week before operation. Foley catheter was placed three days before surgery and irrigated with saline. After relief of abdominal distention, robotic-assisted abdominoperineal resection+ subtotal colectomy+colostomy was performed. Results: Water intake within 6 hours post-operatively; ambulance on Day 1; anal passage of gas on Day 2; semi-fluid diet on Day 3; safely discharged on Day 6. Conclusion: Robotic-assisted minimally invasive surgery is safe and feasible for patients with malignant tumor of anal canal combined with severe abdominal distention after appropriate and effective preoperative preparation to relieve abdominal distention.

ABSTRACT

OBJECTIVE@#To describe the secular trends of age at menarche and age at natural menopause of women from a county of Shandong Province.@*METHODS@#Based on the data of the Premarital Medical Examination and the Cervical Cancer and Breast Cancer Screening of the county, the secular trends of age at menarche in women born in 1951 to 1998 and age at menopause in women born in 1951 to 1975 were studied. Joinpoint regression was used to identify potential inflection points regarding the trend of age at menarche. Average hazard ratios (AHR) of early menopause among women born in different generations were estimated by performing multivariate weighted Cox regression.@*RESULTS@#The average age at menarche was (16.43±1.89) years for women born in 1951 and (13.99±1.22) years for women born in 1998. The average age at menarche was lower for urban women than that for rural women, and the higher the education level, the lower the average age at menarche. Joinpoint regression analysis identified three inflection points: 1959, 1973 and 1993. The average age at menarche decreased annually by 0.03 (P < 0.001), 0.08 (P < 0.001), and 0.03 (P < 0.001) years respectively for women born during 1951-1959, 1960-1973, and 1974-1993, while it remained stable for those born during 1994-1998 (P=0.968). As for age at menopause, compared with women born during 1951-1960, those born during 1961-1965, 1966-1970 and 1971-1975 showed a gradual decrease in the risk of early menopause and a tendency to delay the age at menopause. The stratified analysis presented that the risk of early menopause gradually decreased and the age of menopause showed a significant delay among those with education level of junior high school and below, but this trend was not obvious among those with education level of senior high school and above, where the risk of early menopause decreased and then increased among those with education level of college and above, and the corresponding AHRs were 0.90 (0.66-1.22), 1.07 (0.79-1.44) and 1.14 (0.79-1.66).@*CONCLUSION@#The age at menarche for women born since 1951 gradually declined until 1994 and leveled off, with a decrease of nearly 2.5 years in these years. The age at menopause for women born between 1951 and 1975 was generally delayed over time, but the trend of first increase and then decrease was observed among those with relatively higher education levels. In the context of the increasing delay in age at marriage and childbearing and the decline of fertility, this study highlights the necessity of the assessment and monitoring of women' s basic reproductive health status, especially the risk of early menopause.

ABSTRACT

Objective:To observe the clinical and fundus imaging features of acute macular neuroretinopathy (AMN) associated with COVID-19.Methods:A retrospective case study. A total of 32 eyes of 18 patients diagnosed of AMN associated with COVID-19 at Chengdu Aidi Eye Hospital from December 2022 to February 2023 were included. All patients had a history of fever 1 to 5 days prior to ocular onset and tested positive for SARS CoV-2 antigen. All patients were examined by best-corrected visual acuity (BCVA), color fundus photography, scanning laser ophthalmoscope (SLO), infrared fundus photography (IR), and optical coherence tomography (OCT); OCT angiography, visual field and multifocal electroretinogram (mf-ERG) were performed in 6 patients (11 eyes), 3 patients (6 eyes) and 1 patient (2 eyes), respectively. Follow-up time was 8-10 weeks. The clinical and fundus imaging features were observed and analyzed.Results:There were 6 males (12 eyes) and 12 females (20 eyes), aged from 15 to 36 years, with the mean age of (28.00±5.86) years. Fourteen patients were bilateral and 4 patients were unilateral. The time from the onset of eye symptoms to seeing a doctor was ranged from 1 day to 8 weeks. Among them, 6 patients (10 eyes) visited the doctor within 3 days of onset, while 12 patients (22 eyes) visited the doctor after 3 days of onset. The BCVA was 0.80±0.29. Fundus color photography and SLO examination showed that only 2 patients (4 eyes) showed sheet or petal-like dark red lesions in the macular area, and no obvious abnormal changes were observed in other patients. No obvious abnormalities were found in AF examination of all patients. IR examination showed no significant abnormality in 6 cases which came to hospital within 3 days after the onset, but irregular hyporeflective dark shadow lesions in the macular region of patients with more than 3-day course of disease was observed. OCT examinations of all eyes showed hyperreflective band or patchy lesion on the outer plexiform layer (OPL) and outer nuclear layer (ONL) and affect the ellipsoid zone (EZ) and interdigitation zone (IZ). In 11 eyes of 6 patients undergoing OCTA examination, the blood flow density of the choroidal capillary layer in the focal area decreased. In 6 eyes of 3 patients who underwent visual field examination, the physiologic scotoma was slightly enlarged. One patient (2 eyes) receiving mf-ERG showed a concave reduction in macular center amplitude. The hyperreflective band lesion on OPL and ONL disappear rapidly within 2 weeks, while the continuity of EZ recovered slowly, and the disruption of IZ kept existing for more than 10 weeks.Conclusions:Most AMN associated with COVID-19 are young women; IR showed irregular weak reflex in the lesion area. OCT showed strong OPL and ONL reflection. OCTA was characterized by decreased blood flow density in the choroidal capillary layer of the focal area.

ABSTRACT

Antibacterial therapy is a global health issue. The antibiotic resistance is becoming an increasingly serious threat, which caused by misuse and overuse of antibacterial agents combined with the emergence of new resistance mechanism. The resulting infection treatment risk and incidence of the spread of disease, severe cases and deaths are increased in different degrees. With the extensive application of biomaterials and nanotechnology to biomedicine, extensive research has been conducted on antibacterial infection. With the specific physicochemical properties like optical, electric and magnetic and high penetration, inorganic nanomaterials can produce natural antibacterial effect. Nanomedicine can be designed to allow controlled drug release and targeting effect, thus demonstrated better antibacterial efficiency. In this review, the mechanism of antibacterial resistance is described, and the antibacterial infection research on inorganic nanomaterials, as well as nano-drug delivery system including liposomes, nanoparticles, dendrimers and biomimetic nanocarriers are summarized. Nanomaterials and nanotechnology offer promising strategies for the development of new agents that can improve efficacy on antibacterial infections and overcome antibiotic resistance potentially.

ABSTRACT

Objective: Exploring the neuropsychological developmental characteristics and influencing factors of children with speech disorder. Methods: A case-control study was conducted. A total of 395 children diagnosed with speech disorders were selected as speech sound disorder (SSD) group from January 2019 to September 2021 in the speech-speech outpatient department of the Children's Hospital Affiliated to Capital Institute of Pediatrics, and 1 179 healthy children who underwent physical examination in the health department during the same period were selected as the control group. All the children were examined by the "Children's Neuropsychological Behavior Scale 2016 Edition" (Children's Mind Scale 2016 edition). Independent sample t test was used to compare the developmental levels of the two groups of children, including total developmental quotient, gross motor, fine motor, adaptive ability, language and social behavior ability. The influential factors of children's speech disorders were analyzed by univariate Chi-square analysis and multivariate logistic regression. Results: There were 395 SSD children, including 296 males and 99 females, 4≤ age ≤6, (4.71±0.76) years. There were 1 179 children in the control group, including 864 males and 315 females, 4≤ age ≤6, (4.64±0.78) years. The mean value of total developmental factors in SSD group was lower than that in control group [(86.45±11.57)/(91.24±8.0), t=-7.78, P<0.01], and the mean values of total developmental markers in both boys and girls in SSD group were lower than those in control group [(86.00±11.40)/(90.78±7.86), t=-6.70, P<0.01; (87.82±12.03)/(92.87±8.49), t=-3.88, P<0.01]. The mean values of gross motor, fine motor, adaptive ability, language ability and social behavior in SSD group were lower than those in control group [(89.76±12.47)/(92.01±10.69), t=-3.21, P<0.01; (80.62±13.64)/(84.49±11.55), t=-5.06, P<0.01; (87.92±15.25)/(92.98±12.06), t=-6.00, P<0.01; (86.48±16.30)/(94.55±12.08), t=-9.04, P<0.01; (87.02±15.18)/(92.63±12.57), t=-6.62, P<0.01]; The mean value of fine motor in boys was lower than that in girls in SSD group [(79.80±13.42)/(83.08±14.05), t=-2.08, P<0.05]. Independent mealtimes. 2 years old (OR=1.527, 95%CI: 1.180-1.977, P=0.001), delay in adding supplemental food (OR=1.510, 95%CI: 1.123-2.029, P=0.006), dialect in the home language environment (OR=1.351, 95%CI: 1.060-1.723, P=0.015) were risk factors for children with speech disorders. Conclusion: Children with speech disorders are more common in boys. The overall development level of SSD children is lower than that of normal children, and the fine motor of SSD boys is lower than that of girls. The incidence of children's speech disorders is related to the addition time of supplementary food, independent meal time and family language environment.

ABSTRACT

Alzheimer's disease (AD) is associated with the impairment of white matter (WM) tracts. The current study aimed to verify the utility of WM as the neuroimaging marker of AD with multisite diffusion tensor imaging datasets [321 patients with AD, 265 patients with mild cognitive impairment (MCI), 279 normal controls (NC)], a unified pipeline, and independent site cross-validation. Automated fiber quantification was used to extract diffusion profiles along tracts. Random-effects meta-analyses showed a reproducible degeneration pattern in which fractional anisotropy significantly decreased in the AD and MCI groups compared with NC. Machine learning models using tract-based features showed good generalizability among independent site cross-validation. The diffusion metrics of the altered regions and the AD probability predicted by the models were highly correlated with cognitive ability in the AD and MCI groups. We highlighted the reproducibility and generalizability of the degeneration pattern of WM tracts in AD.
