ABSTRACT

Alzheimer's disease (AD) is a leading cause of dementia in the elderly. Mitogen-activated protein kinase phosphatase 1 (MKP-1) plays a neuroprotective role in AD. However, the molecular mechanisms underlying the effects of MKP-1 on AD have not been extensively studied. MicroRNAs (miRNAs) regulate gene expression at the post-transcriptional level, thereby repressing mRNA translation. Here, we reported that the microRNA-429-3p (miR-429-3p) was significantly increased in the brain of APP23/PS45 AD model mice and N2AAPP AD model cells. We further found that miR-429-3p could downregulate MKP-1 expression by directly binding to its 3'-untranslated region (3' UTR). Inhibition of miR-429-3p by its antagomir (A-miR-429) restored the expression of MKP-1 to a control level and consequently reduced the amyloidogenic processing of APP and Aβ accumulation. More importantly, intranasal administration of A-miR-429 successfully ameliorated the deficits of hippocampal CA1 long-term potentiation and spatial learning and memory in AD model mice by suppressing extracellular signal-regulated kinase (ERK1/2)-mediated GluA1 hyperphosphorylation at Ser831 site, thereby increasing the surface expression of GluA1-containing α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs). Together, these results demonstrate that inhibiting miR-429-3p to upregulate MKP-1 effectively improves cognitive and synaptic functions in AD model mice, suggesting that miR-429/MKP-1 pathway may be a novel therapeutic target for AD treatment.

ABSTRACT

Objective: To investigate the clinicopathological characteristics, diagnosis and differential diagnosis of intravascular large B-cell lymphoma (IVLBCL) and its collision tumors. Methods: Five cases of IVLBCL were collected, including 2 cases of collision tumors, and 1 case complicated with liver cirrhosis. The morphology and immunophenotype were analyzed. The related literature was reviewed. Results: There were 2 females and 3 males, aged from 53 to 73 years, with a median age of 65 years. The tumors were located in the lower extremities, right cerebellar hemisphere, left kidney, bilateral nasal cavity, and liver, respectively. Cases 2 and 3 were incidentally found in meningioma and renal cell carcinoma tissues, respectively. Case 5 had a background of liver cirrhosis. Morphologically, atypical large lymphoid cells were located in small blood vessels and capillary lumen, with little cytoplasm, hyperchromasia, prominent nucleoli, and obvious mitotic figures. Immunohistochemically, the IVLBCL tumor cells expressed CD20 and PAX5; 2 cases were CD5 positive. One of the 5 cases was GCB phenotype, and 4 cases were non-GCB phenotype. All cases expressed C-MYC (positive rate was 10%-40%). PD-L1 was positive in 4 cases (positive rate was 60%-90%). Ki-67 proliferation index was 70%-90%. CKpan, CD3, TDT, and CD34 were negative. In case 2, meningioma cells were positive for PR, EMA, and vimentin, but negative for CKpan and PD-L1. In case 3, renal carcinoma cells were positive for CKpan, PAX8, EMA, vimentin, CAⅨ and CD10, while PD-L1 was negative. No EBER expression (by in situ hybridization) or C-MYC gene translocation (FISH, break-apart probe) was detected in any of the 5 cases. Three patients were followed up, and all died within 1-13 months. Conclusions: IVLBCL is a highly aggressive lymphoma, with occult clinical manifestations and poor prognosis. Collision tumors of IVLBCL are extremely rare. A better understanding of IVLBCL would help pathologists avoid misdiagnoses.

ABSTRACT

Objective:To explore the correlation between attempted suicide and childhood trauma as well as inflammatory cytokines levels in adolescents with depressive disorder.Methods:From January to December 2021, a total of 164 adolescents with depressive disorder were included and categorized into attempted suicide group ( n=108) and non-attempted suicide group ( n=56) according to whether they accompanied attempted suicide or not. The Chinese version of the suicide module of MINI 5.0, the childhood trauma questionnaire(CTQ), and the center for epidemiological studies depression scale (CES-D) were used to assess suicidal behavior, childhood trauma and depressive symptoms, while the plasma inflammatory cytokines levels were measured by electrochemiluminescence technology. The data were statistically analyzed by SPSS 23.0 software. Logistic regression was applied to analyze the independent influencing factors of attempted suicide and the predictive value of each independent risk factor for attempted suicide was assessed by receiver operating characteristic curve(ROC) curves. Results:The prevalence of attempted suicide was 65.9%(108/164) in adolescents with depressive disorder.The univariate analyses showed that the total CTQ score ((55.19±12.44), (45.50±12.11)) ( t=-4.771, P<0.001), CES-D total score ((40.75±10.26), (32.98±13.39)) ( t=-4.131, P<0.001), IL-6 level(1.87 (1.32, 2.69) pg/mL, 1.56 (1.05, 1.87) pg/mL)( Z=-3.102, P=0.002), IL-10 level (0.53 (0.38, 0.83) pg/mL, 0.47 (0.31, 0.69) pg/mL) ( Z=-2.100, P=0.036) and IL-17A level (2.20 (1.52, 3.65) pg/mL, 1.67 (1.25, 2.97) pg/mL) ( Z=-2.254, P=0.024) in plasma of patients in the attempted suicide group were significantly higher than those in non-attempted suicide group. Logistic stepwise regression analyses showed that CTQ total score, IL-6, IL-10, and IL-17A were risk factors for attempted suicide in adolescents with depressive disorder.The ROC showed that the total score of CTQ combined with IL-6 (AUC=0.782, 95% CI=0.709-0.855, P<0.001), the total score of CTQ combined with IL-10 (AUC=0.765, 95% CI=0.688-0.841, P<0.001), and the total score of CTQ combined with IL-17A (AUC=0.762, 95% CI=0.684-0.840, P<0.001) had a larger area under the curve, indicating better recognition and prediction ability for attempted suicide, with high sensitivity and specificity. Conclusion:The incidence of attempted suicide in adolescents with depressive disorder is high, and which is closely related to childhood trauma and the levels of inflammatory cytokines.

ABSTRACT

Liver is a common site for distant metastasis of colorectal cancer and a large proportion of patients with colorectal liver metastasis cannot receive the radical hepatectomy. Liver transplantation has been proven to bring a survival benefit in highly selected unresectable colorectal liver metastasis (u-CRLM) patients, but the shortage of donor liver severely restricts its application. Resection and partial liver transplantation with delayed total hepatectomy (RAPID) is a newly deve-loped liver transplantation procedure, which innovatively combined auxiliary liver transplantation and associating liver partition and portal vein ligation for staged hepatectomy. With the small and partial liver graft, RAPID can cure u-CRLM safely and effectively. In RAPID, the reconstruction of portal vein and hepatic vein is the key point, while the control of portal vein pressure and flow is the difficulty and also the key for success. Thereafter, living donor-RAPID is created by combing RAPID with living donor liver transplantation. Besides, the application of RAPID also extends to other primary liver diseases, including liver cirrhosis and liver cancer. RAPID is difficult, complex and under an exploratory stage at present. In this paper, based on the developing process of RAPID, the authors give a comprehensive overview of its surgical procedures and key points, and discuss its potential application area.

ABSTRACT

Objective:To analyze the distribution of ages at the interhospital transfer of outborn very preterm infants in China and to compare their perinatal characteristics and outcomes at discharge and neonatal intensive care unit (NICU) treatment.Methods:A total of 3 405 outborn very premature infants with a gestational age of 24-31 +6 weeks who were transferred to the NICUs of the Chinese Neonatal Network (CHNN) in 2019 were included in this retrospective study. According to the age at transfer, they were divided into three groups: early transfer (≤1 d), delayed transfer (>1-7 d) and late transfer (>7 d) groups. Analysis of variance, t-test, Chi-square test (Bonferroni correction), Kruskal-Wallis test and Wilcoxon rank-sum test were used to compare the general clinical condition, treatment, and outcomes at discharge among the three groups. Results:The median gestational age was 29.7 weeks (28.3-31.0 weeks) and the average birth weight was (1 321.0 ± 316.5) g for these 3 405 infants. There were 2 031 patients (59.6%) in the early transfer group, 406 (11.9%) in the delayed transfer group and 968 (28.4%) in the late transfer group. Infants who received continuous positive airway pressure ventilation and tracheal intubation in the delivery room accounted for 8.4% (237/2 806) and 32.9% (924/2 805), respectively. A total of 62.7% (1 569/2 504) of the mothers received antenatal glucocorticoid therapy and the ratio in the early transfer group was 68.7% (1 121/1 631), which was higher than that in the delayed transfer group [56.1% (152/271), χ2=16.78, P<0.017] and the late transfer group [49.2% (296/602), χ2=72.56, P<0.017]. The total mortality rate of very premature infants was 12.7% (431/3 405), and the mortality rates in the early, delayed and late transfer groups were 12.4% (252/2 031), 16.3% (66/406) and 11.7% (113/968), respectively ( χ2=5.72, P=0.057). The incidences of severe intraventricular hemorrhage, late-onset sepsis, necrotizing enterocolitis, and bronchopulmonary dysplasia at the corrected gestational age of 36 weeks or discharge were all higher in the delayed and late transfer groups than in the early transfer group, respectively. The incidences of retinopathy of prematurity, retinopathy of prematurity requiring treatment and bronchopulmonary dysplasia at the corrected gestational age of 36 weeks or discharge in the late transfer group were significantly higher than that in the delayed transfer group (Bonferroni correction, all P<0.017). In the late transfer group, the median age of very premature infants at discharge was 66.0 d (51.0-86.0 d), and the corrected gestational age at discharge was 38.9 weeks (37.1-41.2 weeks), and both were greater than those in the early transfer [48.0 d (37.0-64.0 d), Z=260.83; 36.9 weeks (35.7-38.3 weeks), Z=294.32] and delayed transfer groups [52.0 d (41.0-64.0 d), Z=81.49; 37.4 weeks (36.1-38.7 weeks), Z=75.97] (all P<0.017). Conclusions:Many very premature infants need to be transferred to higher-level hospitals after birth. The later the very premature infants are transferred, the higher the incidence of complications will be. It is suggested that intrauterine or early postnatal transport may improve the prognosis of very premature infants.

ABSTRACT

Objective:To investigate the effect of tripartite motif-containing 23 (Trim23) on the differentiation and maturation of dendritic cells and the possible mechanism.Methods:Mouse bone marrow-derived dendritic cells (BMDCs) were prepared from bone marrow cells of C57BL/6 mice with the presence of Flt3L. Real-time quantitative PCR and Western blot were used to detect the expression of Trim23 in BMDCs after LPS stimulation. An overexpression vector for full-length Trim23 (Trim23 OE) was constructed and transfected into BMDCs, and the pcDNA3.1 empty vector was used as control. Flow cytometry was used to detect the expression of CD80, CD86, CD40 and MHCⅡ on the surface of vector-transfected BMDCs after LPS stimulation and ELISA was used to detect the secretion of IL-12p40, TNF-α, IL-6 and IL-10 by these cells. CD8 + and CD4 + T cells were isolated from spleen and lymph nodes of OT-Ⅰ and OT-Ⅱ mice by magnetic beads and co-cultured with LPS-treated BMDCs in the presence of ovalbumin (OVA). Flow cytometry was used to detect the proliferation and differentiation of CD8 + and CD4 + T cells. Western blot was performed to analyze the phosphorylation of p38, ERK1/2 and AKT in BMDCs. Two overexpression vectors for Trim23 mutants lacking RING or ARF domain (Trim23 ΔRING and Trim23 ΔARF) were constructed and transfected into BMDCs. Then flow cytometry and ELISA were used to detect the expression of surface molecules and cytokines. Results:The expression of Trim23 in BMDCs was significantly down-regulated after LPS stimulation. The expression of MHCⅡ, CD86 and CD80 and the secretion of TNF-α and IL-6 decreased significantly in BMDCs overexpressing Trim23. Furthermore, overexpression of Trim23 inhibited the ability of BMDCs to induce the proliferation and differentiation of CD4 + T cells and the proliferation of CD8 + T cells. Western blot showed that the phosphorylation of p38 and ERK1/2 decreased significantly in Trim23-overexpressing BMDCs. Compared with wildtype Trim23, overexpression of Trim23 ΔRING had no significant influence on the expression of surface molecules (MHCⅡ and CD86) and the secretion of cytokines (TNF-α and IL-6) in BMDCs stimulated by LPS. Conclusions:Trim23 overexpression inhibited the maturation and immune activation of BMDCs via MAPK signal pathway and its RING domain. This study provided reference for targeting Trim23 to improve the immune response of dendritic cell-based tumor vaccines.

ABSTRACT

Abstract@#Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

ABSTRACT

Objective: To investigate the factors influencing total bilirubin elevation and its correlation with UGT1A1 gene polymorphism in the early postoperative period of transjugular intrahepatic portosystemic shunt (TIPS). Methods: 104 cases with portal hypertension and esophageal variceal hemorrhage (EVB) treated with elective TIPS treatment were selected as the study subjects and were divided into a bilirubin-elevated group and a normal bilirubin group according to the total bilirubin elevation level during the early postoperative period. Univariate analysis and logistic regression were used to analyze the factors influencing total bilirubin elevation in the early postoperative period. PCR amplification and first-generation sequencing technology were used to detect the polymorphic loci of the UGT1A1 gene promoter TATA box, enhancer c.-3279 T > G, c.211G > A, and c.686C > A. Logistic regression was used to analyze the correlation of four locus alleles and genotypes with elevated total bilirubin in the early postoperative period. Results: Among the 104 cases, 47 patients were in the bilirubin elevated group, including 35 males (74.5%) and 12 females (25.5%), aged (50.72 ± 12.56) years. There were 57 cases in the normal bilirubin group, including 42 males (73.7%) and 15 females (26.3%), aged (51.63 ± 11.10) years. There was no statistically significant difference in age (t = -0.391, P = 0.697) and gender (χ(2) = 0.008, P = 0.928) between the two groups of patients. Univariate analysis revealed that preoperative alanine transaminase (ALT) level (χ(2) = 5.954, P = 0.015), total bilirubin level (χ(2) = 16.638, P < 0.001), MELD score (χ(2) = 10.054, P = 0.018), Child-Pugh score (χ(2) = 6.844, P = 0.022), and postoperative portal vein branch development (χ(2) = 6.738, P = 0.034) were statistically significantly different between the two groups. Logistic regression analysis showed that preoperative ALT level, total bilirubin level, and portal vein branch development after TIPS were correlated with the elevated total bilirubin in the early postoperative period. The polymorphism of the c.211G > A locus of the UGT1A1 gene correlation had elevated total bilirubin in the early postoperative period of TIPS. The risk of elevated total bilirubin was increased in the population carrying allele A (P = 0.001, OR = 4.049) in the early postoperative period. Allelic polymorphisms in the TATA box promoter region and enhancer c.-3279 T > G and c.686C > A had no statistically significant difference between the bilirubin-elevated group and the normal bilirubin group. Conclusion: The preoperative ALT level, total bilirubin level, and portal vein branch development are correlated with the elevated total bilirubin in early postoperative patients. The polymorphisms of the UGT1A1 gene and enhancer c.211G > A are correlated with the occurrence of elevated total bilirubin in the early postoperative period of TIPS. Allele A carrier may have a higher risk of elevated total bilirubin in the early postoperative period.

ABSTRACT

Objective:The evidence-based and Delphi methods were used to construct the exercise program for hospitalized patients with diabetes foot to provide guidance for clinical practice.Methods:Evidence on exercise management of diabetic foot patients was systematically searched from BMJ Best Practice, UpToDate, Registered Nurses′ Association of Ontario and other domestic and foreign databases and professional association websites. The retrieval period was from the establishment of the database to April 2021. The quality of the included literature was independently evaluated, and the evidence of the literature meeting the quality standards was extracted and summarized to form the first draft of exercise program for inpatients with diabetic foot. After two rounds of Delphi expert letter consultation, the program items were revised, and the final draft of the exercise program for inpatients with diabetic foot suitable for clinical practice was formed.Results:The effective recovery rate of the two rounds of expert correspondence questionnaire both were15/15. The expert authority coefficient was 0.865 and 0.895 respectively. And the Kendall coordination coefficient was 0.232 and 0.291 (both P<0.01). An exercise program for inpatients with diabetic foot had been formed, including 5 modules(exercise evaluation, exercise prescription, exercise monitoring, post-exercise evaluation and exercise management), 12 items and 40 operational items. Conclusions:The exercise program for inpatients with diabetic foot constructed in this study is scientific and clinically applicable, which provide scientific guidance for clinical medical staff to carry out exercise practice.

ABSTRACT

Objective@#Excessive daytime sleepiness (EDS) and insomnia symptoms are common in patients with major depressive disorder (MDD), which might lead to a poor prognosis and an increased risk of depression relapse. The current study aimed to investigate the prevalence, and sociodemographic and clinical correlates of EDS and insomnia symptoms among adolescents with MDD. @*Methods@#The sample of this cross-sectional study included 297 adolescents (mean age=15.26 years; range=12–18 years; 218 females) with MDD recruited from three general and four psychiatric hospitals in five cities (Hefei, Bengbu, Fuyang, Suzhou, and Ma’anshan) in Anhui Province, China between January and August, 2021. EDS and insomnia symptoms, and clinical severity of depressive symptoms were assessed using Epworth sleepiness scale, Insomnia Severity Index, and Clinical Global Impression-Severity. @*Results@#The prevalence of EDS and insomnia symptoms in adolescents with MDD was 39.7% and 38.0%, respectively. Binary logistic regression analyses showed that EDS symptoms were significantly associated with higher body mass index (odds ratio [OR]=1.097, 95% confidence interval [CI]=1.027–1.172), more severe depressive symptoms (OR=1.313, 95% CI=1.028–1.679), and selective serotonin reuptake inhibitors use (OR=2.078, 95% CI=1.199–3.601). And insomnia symptoms were positively associated with female sex (OR=1.955, 95% CI=1.052–3.633), suicide attempts (OR=1.765, 95% CI=1.037–3.005), more severe depressive symptoms (OR=2.031, 95% CI=1.523–2.709), and negatively associated with antipsychotics use (OR=0.433, 95% CI=0.196–0.952). @*Conclusion@#EDS and insomnia symptoms are common among adolescents with MDD. Considering their negative effects on the clinical prognosis, regular screening and clinical managements should be developed for this patient population.

ABSTRACT

Objective:To study the neurodevelopmental prognosis and risk factors for adverse outcomes of neonatal seizure.Methods:From December 2019 to November 2020, infants with neonatal seizure diagnosed in our hospital were enrolled in this retrospective study. Based on survival or not, mental development index (MDI), psychomotor development index (PDI) and seizure episodes at the age of 12 months, the infants were assigned into adverse outcome group and normal outcome group. The risk factors for adverse outcomes were statistically analyzed.Results:A total of 75 infants were enrolled,including 39 cases in adverse outcome group and 36 in normal outcome group. 69 cases showed abnormal amplitude-integrated electroencephalogram(aEEG), including 38 mildly abnormal cases,23 moderately abnormal cases and 8 severely abnormal cases, The incidences of adverse outcomes and mortality rates were significantly different ( P<0.05) among infants with different severity levels of aEEG abnormalities and the severity levels of aEEG abnormalities were positively correlated with adverse outcomes ( r=0.367, 0.471, P<0.05).Univariate analysis showed that adverse outcome group had significantly higher incidences of chorioamnionitis, seizure onset age ≤3 d, 5 min Apgar score ≤3, cranial ultrasound abnormalities, brain MR abnormalities and aEEG abnormalities than normal outcome group ( P<0.05).Logistic regression analysis showed that seizure onset age ≤3 d ( OR=3.988, 95% CI 1.376-11.674), abnormal brain MR ( OR=3.296, 95% CI 2.383-17.377) and bilirubin encephalopathy ( OR=3.792,95% CI 2.110-13.216) were independent risk factors for adverse outcomes of neonatal seizure. Conclusions:For neonatal seizure, the infants with more severe abnormal aEEG will have higher incidences of adverse outcomes and mortality. Seizure onset age ≤3 d, brain MR abnormalities and bilirubin encephalopathy were independent risk factors for adverse outcomes of neonatal seizure.

ABSTRACT

Objective:To study the clinical characteristics and risk factors of intrauterine Ureaplasma urealyticum (UU) infection in very low birth weight preterm infants.Methods:From March 2019 to February 2022, very low birth weight preterm infants with gestational age 28~32 weeks admitted to our hospital were enrolled in this single-center retrospective study. According to the UU test results of respiratory tract samples obtained within 24 h after admission, the infants were assigned into the UU group (UU-PCR positive) and the non-UU group (UU-PCR negative). SPSS 26.0 statistical software was used to compare the clinical characteristics, laboratory indices, and complications between the two groups. Risk factors of UU infection were calculated.Results:A total of 327 preterm infants were included: 45 in the UU group and 282 in the non-UU group. No significant differences existed in gender, gestational age, birth weight and delivery pattern between the two groups ( P>0.05). Compared with the non-UU group, the UU group had significantly higher incidences of premature rupture of membranes (PROM) and chorioamnionitis, elevated white blood cell and platelet counts, procalcitonin and C-reactive protein levels, total duration of oxygen use and ventilation, bronchopulmonary dysplasia, necrotizing enterocolitis and metabolic osteopathy ( P<0.05). Multivariate logistic regression analysis showed that PROM ( OR=5.444, 95% CI 2.749-10.781, P<0.001) and chorioamnionitis ( OR=2.161, 95% CI 1.048-4.454, P=0.037) were independent risk factors for UU infection. Conclusions:PROM and chorioamnionitis are risk factors for UU infection in very low birth weight preterm infants. For high-risk premature infants, the UU test should be completed as soon as possible after birth.

ABSTRACT

Objective:To study the complications and prognosis of extremely premature infants(EPIs) with gestational age (GA) <28 w.Methods:From January 2016 to December 2020, EPIs with GA <28 w admitted to NICU of our hospital were retrospectively studied. Clinical data of the infants and their mothers during pregnancy were reviewed. According to the prognosis, the infants were assigned into the survival group, the death group and the withdrawal group. According to GA, the infants were assigned into <26 w goup, 26~26 +6 w group, ≥27 w group. According to birth weight (BW), the infants were assigned in to ≤750 g group, 750~999 g group and ≥1 000 g group. SPSS 26.0 was used for data analysis. Results:A total of 265 EPIs were included, 122 (46.0%) in the survival group, 47 (17.7%) in the death group and 96 (36.2%) in the withdrawal group. GA and BW of the survival group were significantly higher than the death group and the withdrawal group ( P<0.05). The incidences of tracheal intubation (92.2%) and pulmonary hemorrhage (42.2%) in the death group were the highest among the three groups. The survival group had the highest application of prenatal glucocorticoids (80.3%) and pulmonary surfactants (99.2%) ( P<0.05). In the survival group, the top 3 common complications were bronchopulmonary dysplasia (BPD) (68.0%), pulmonary infections (65.6%) and neonatal sepsis (34.4%). The survival rate increased with GA and BW. Conclusions:The survival rate of EPIs is closely correlated with GA and BW. EPIs with pulmonary hemorrhage and tracheal intubation have poor prognosis. Prenatal glucocorticoids and pulmonary surfactant may improve clinical outcome. BPD and pulmonary infections are common complications of surviving EPIs.

ABSTRACT

Objective:To study the current status of critical neonatal care centers (CNCC) construction and treatment of critically-ill neonates at city- and county-level in Henan Province.Methods:A questionnaire survey was conducted in January 2022 to city- and county-level CNCC in Henan Province. The basic information of CNCC, ward settings, neonatal management in the Department of Obstetrics and the treatment of critically-ill neonates in 2019-2021 were analyzed.Results:A total of 188 questionnaires were sent and 183 (97.3%) eligible questionnaires were analyzed, including 30 from city centers and 153 from county centers. The bed occupancy rate in county centers was significantly lower than city centers (67.3%±24.1% vs. 86.1%±23.2%), and the doctor/bed ratio, doctor/rescue bed ratio and nurse/rescue bed ratio were significantly higher than city centers ( P<0.05). All city centers had set up independent Department of Neonatology and the number is 92.8% (142/153) in county center. For 80.9% (148/183) centers, neonates were managed in the Department of Obstetrics with consultations and referrals to the Department of Pediatrics and 19.1% (35/183) were managed in the Department of Pediatrics/Neonatology. The average number of deliveries and admissions to the Department of Neonatology in both city and county centers decreased year on year during 2019-2021, but the proportion of premature and low/very low birth weight infants treated in these centers increased year on year. During 2019-2021, the top three diseases treated at the city centers were neonatal respiratory distress syndrome, neonatal asphyxia and acute respiratory distress syndrome, while the top three diseases treated at the county centers were neonatal asphyxia, neonatal respiratory distress syndrome and meconium aspiration syndrome. The incidence of sudden infant death syndrome in city and county centers was (10~30)/100,000. Conclusions:The construction of CNCC in Henan Province is facing challenges such as decreased hospital admissions, increased critically-ill neonates, insufficient cooperation between Obstetrics and Pediatrics and waste of resources. Rationally allocated and optimised use of resources to improve the ability to treat critically-ill neonates is warranted.

ABSTRACT

Objective:The included angle of the outermost edge of the pedicle and the front edge of the central line of T12, L1, and L12 in the axial projection was compared before surgery (the incidence angle of the pedicle was set as α). A horizontal line passing through point C was made to cross the inner edge of the pedicle in the axial projection and the intersection point was designated as point D. The distance between point C and point D was compared among T12, L1, and L2. The advantages and feasibility of the measurement of these parameters for guiding puncture and bone cement injection in L1 percutaneous vertebroplasty were investigated.Methods:The clinical data of 91 patients with L1 osteoporotic vertebral compression fracture who underwent percutaneous vertebroplasty in The First People's Hospital of Chu Zhou from January 2018 to November 2021 were retrospectively analyzed. Axial α and CD of the L1 vertebral body and its adjacent vertebral bodies were measured. The amount of bone cement injected during the surgery, bone cement leakage rate, and pre- and post-surgery Visual Analogue Scale score were determined.Results:The α and CD of L1 in the axial projection were (20.43 ± 1.61)° and (5.37 ± 1.08) mm, respectively. Bone cement leakage rates of unilateral and bilateral approaches of L1 vertebral body were 35% and 12%, respectively, and there was a significant difference between the two approaches ( χ2 = 6.08, P < 0.05). There was no significant difference in the amount of bone cement injected during the surgery between unilateral and bilateral approaches of L1 ( P > 0.05). There was no significant difference in pre- and post-surgery Visual Analogue Scale scores between unilateral and bilateral approaches of L1 ( P > 0.05). Conclusion:The α and CD of L1 in the axial projection are smaller than those of other adjacent vertebral bodies, which is of great significance for selecting a puncture path and reducing bone cement leakage.

ABSTRACT

The occurrence and development of malignant tumors seriously affect the survival time and quality of life of people all over the world, and finding proper treatment methods has been a focus for doctors. Especially in recent years, traditional Chinese medicine (TCM) has developed and attracted the attention of doctors and patients. From the perspective of TCM syndrome differentiation and treatment, deficiency and stasis are the most fundamental causes of malignant tumors, and supplementing deficiency and removing stasis can be regarded as the basic criteria of TCM treatment of malignant tumors. TCM prescriptions can treat diseases by means of multiple components and multiple targets, with the characteristics of slight side effect and high efficacy, safety and cost performance, as well as easiness to be accepted and taken. As a classic recipe for invigorating Qi and generating blood, Danggui Buxuetang consists of Astragali Radix -Angelicae Sinensis Radix 5∶1. It has excellent effects in anti-tumor, bone marrow suppression after chemotherapy, immune function decline, anemia, heart and cerebral vessels protection, blood deficiency-led fever, diabetes, anti-atherosclerosis, anti-fatigue, anti-radiation, myocardial ischemia alleviation, inhibition of platelet aggregation, liver damage, etc. In addition, with many active anti-tumor ingredients, Danggui Buxuetang can exert anti-tumor effects via acting on multiple targets in different binding sites. However, there has been a lack of reviews on the role of Danggui Buxuetang in malignant tumors so far. Therefore, in this paper, the functions of Danggui Buxuetang in malignant tumors were reviewed. Besides, molecular docking technology was used to analyze the main active anti-tumor ingredients and action targets of Danggui Buxuetang.

ABSTRACT

Hederin is a natural active component of triterpenoid saponins extracted from many medicinal herbs, such as Lithospermum erythrorhizon, Pulsatilla chinensis, and Clematis florida. It has attracted much attention from doctors for its anti-inflammatory, anti-convulsive, anti-oxidation and anti-leishmaniasis activities. Hederin has significant anti-tumor bioactivity and is expected to be a potential drug for the treatment of malignant tumors. The available studies have demonstrated that hederin can promote the apoptosis, inhibit the proliferation, metastasis, and invasion, and induce the autophagy of tumor cells, exhibiting a promising prospect in the treatment of breast cancer, lung cancer, liver cancer, and pancreatic cancer. Specifically, hederin can regulate the phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) pathway, reactive oxygen species (ROS), and microRNA (miRNA) to trigger tumor cell apoptosis. Its anti-proliferation activity is mainly reflected in the regulation of cyclin and cyclin-dependent kinase (CDK). Hederin inhibits the metastasis and invasion of tumor cells by blocking epithelial-mesenchymal transformation (EMT). In addition, hederin can influence metabolic reprogramming to induce tumor cell autophagy. Hederin is involved in a variety of pathways to exert its anti-tumor activity and may become a novel anti-tumor drug in the future, which give new sights into the study of hederin in the anti-tumor field. There are few studies about hederin and no systematic review of its anti-tumor mechanisms. Therefore, this study reviewed the studies about the anti-tumor mechanism of hederin, aiming to provide reference and information for researchers and clinical staff.

ABSTRACT

Radiotherapy uses high-energy X-rays or other particles to destroy cancer cells and medical practitioners have used this approach extensively for cancer treatment (Hachadorian et al., 2020). However, it is accompanied by risks because it seriously harms normal cells while killing cancer cells. The side effects can lower cancer patients' quality of life and are very unpredictable due to individual differences (Bentzen, 2006). Therefore, it is essential to assess a patient's body damage after radiotherapy to formulate an individualized recovery treatment plan. Exhaled volatile organic compounds (VOCs) can be changed by radiotherapy and thus used for medical diagnosis (Vaks et al., 2012). During treatment, high-energy X-rays can induce apoptosis; meanwhile, cell membranes are damaged due to lipid peroxidation, converting unsaturated fatty acids into volatile metabolites (Losada-Barreiro and Bravo-Díaz, 2017). At the same time, radiotherapy oxidizes water, resulting in reactive oxygen species (ROS) that can increase the epithelial permeability of pulmonary alveoli, enabling the respiratory system to exhale volatile metabolites (Davidovich et al., 2013; Popa et al., 2020). These exhaled VOCs can be used to monitor body damage caused by radiotherapy.

ABSTRACT

Objective:To study the pathogen profile and clinical characteristics of catheter-related bloodstream infection (CRBSI) in very low birth weight infants (VLBWI) receiving peripherally inserted central venous catheter (PICC).Methods:From November 2018 to October 2021, VLBWI with CRBSI after PICC admitted to neonatal intensive care unit (NICU) of our hospital were retrospectively studied. The pathogen profile and drug resistance characteristics were analyze. The infants with bacterial infection were assigned into gram-negative (G -) group and gram-positive (G +) group. Their general status, PICC duration and the site of PICC, body weight at infection, use of lipid emulsion and prophylactic antibiotics, clinical manifestations and laboratory results were compared between the two groups. Results:A total of 70 infants with CRBSI were included and 70 strains of pathogenic bacteria were detected. 50.0% (35/70) were G - bacteria with klebsiella pneumoniae (34.3%, 12/35) and serratia marcescens (34.3%, 12/35) as the most common bacteria. Klebsiella pneumoniae showed more severe drug resistance. 47.1% (33/70) were G + bacteria and the most common strain was staphylococcus epidermidis (45.5%, 15/33) with a majority of methicillin-resistant (86.7%, 13/15). 2 cases (6.1%, 2/33) had bacillus cereus infection and both suffered quick death. 2.9% (2/70) were fungi infection. The main clinical manifestation of CRBSI in VLBWI was apnea and shock was the most common complication. G + group showed significantly higher gestational age and lipid emulsion usage but lower body weight than G - bacteria group. No significant differences existed in clinical manifestations, laboratory results and prognosis between the two groups. Conclusions:Most pathogens causing CRBSI in VLBWI with PICC are opportunistic pathogens. It is difficult to differentiate G + and G - bacterial infection based on clinical manifestations and laboratory results. However, VLBWI with higher gestational age and lipid emulsion usage but lower body weight are more susceptible to G + bacterial infection.

ABSTRACT

Objective:To explore the effect of step-by-step fusion sandplay therapy on clinical symptoms, emotional cognition and quality of life in children with autism spectrum disorder(ASD).Methods:Eighty children with ASD who were admitted in Zhumadian Central Hospital and the Third Affiliated Hospital of Zhengzhou University from January 2019 to January 2021 were selected as the research objects, and they were divided into the study group( n=45) and the control group ( n=35) according to the random number table method.The children in control group were given structured education combined with auditory system training intervention, while the children in study group were given step-by-step fusion sandplay therapy combined with pretend play training on the basis of the control group.Children in the two groups were intervened for 6 months.Autism behavior checklist (ABC), childhood autism rating scale (CARS), social responsiveness scale (SRS), emotion recognition tools and pediatric quality of life (PedsQL) were applied before and after 6 months of intervention.The scores of ABC, SRS, CARS, emotion recognition and PedsQL were compared between the two groups, and Pearson correlation analysis was used to analyze the relationships between the scores of ABC, SRS, CARS, emotion cognition and PedsQL. Results:Compared with pre-intervention, the two groups of children after 6 months of intervention, the sensation, social interaction, body movement, language, self, ABC total score, social perception, social cognition, social communication, social motivation, autistic behavior, SRS total score and CARS scores decreased ( tstudy group= 5.182, 7.200, 6.778, 7.302, 5.140, 36.178, 3.955, 15.294, 9.014, 11.063, 9.723, 45.354, 25.827, all P<0.05, tcontrol group= 1.971, 2.612, 1.665, 2.294, 2.129, 10.809, 2.305, 5.544, 2.650, 2.955, 2.849, 16.485, 5.910, all P<0.05), upright, inverted, upper half face, lower half face emotion discrimination rate, physiological function, emotional function, social function, school function and PedsQL total scores all increased ( tstudy group= 16.723, 31.037, 10.951, 7.234, 7.572, 7.393, 9.036, 7.236, 6.223, all P<0.05. tcontrol group= 5.458, 14.008, 4.196, 2.653, 3.260, 3.566, 3.298, 2.766, 3.876, all P<0.05). After 6 months of intervention, the ABC total score and the scores of sensation, social interaction, body movement, language, and self-care of children in the study group were all lower than those in the control group (ABC total score difference: the study group (21.9±2.8) points, the control group (7.5±2.6) points), t=23.537, P<0.05). The scores of social perception, social cognition, social communication, social motivation, autistic behavior and SRS total score were all lower than those in the control group (SRS total score difference: study group (18.7±0.7) points, control group (8.1±0.6) points, t=71.448, P<0.05). The CARS score of study group was lower than that in control group (CARS score difference: study group (7.7±1.1) points, control group (2.2±0.8) points, t=24.887, P<0.05), while the scores of upright, inverted, upper and lower face emotion discrimination rate, physiological function, emotional function, social function, school function and the PedsQL total score were all higher than those in the control group (PedsQL total score difference: study group (8.4±1.2) points, control group (0.7±0.9) points, t=31.648, P<0.05). Correlation analysis showed that the ABC total score, SRS total score, and CARS score of children with ASD were negatively correlated with physiological function, emotional function, social function, school function and PedsQL total score ( rABC total score=-0.387, -0.334, -0.324, -0.289, -0.349, all P<0.05. rSRS total score = -0.390, -0.343, -0.299, -0.283, -0.378, all P<0.05. rCARS score = -0.321, -0.298, -0.293, -0.235, -0.319, all P<0.05). Upright, inverted, upper and lower faces were positively correlated with physiological function, emotional function, social function, school function and PedsQL total score ( rupright=0.837, 0.650, 0.669, 0.710, 0.680, all P<0.05. rinversion=0.688, 0.611, 0.615, 0.602, 0.647, all P<0.05. rupper half face=0.755, 0.669, 0.638, 0.740, 0.629, all P<0.05. rlower half face=0.738, 0.724, 0.553, 0.568, 0.560, all P<0.05). Conclusion:The step-by-step fusion sandplay therapy can effectively alleviate the clinical symptoms of children with ASD, improve their social responsiveness, and improve their emotional cognitive function and quality of life.
