Objective To explore the association between green space and the risk of dyslipidemia. Methods ^“Dyslipidemia^” and ^“ Normalized Difference Vegetation Index (NDVI)^” were used as search terms to search PubMed, Embase, and Web of Science databases for studies up to September 2023. ARHQ statistical assessment and review tool and NOS scale were employed to evaluate the quality of the studies. R 4.3.1 software was used for meta-analysis. Results A total of 11 studies were included, of which 5 cross-sectional studies and 5 cohort studies were rated as ^“high quality^”. The results of meta-analysis showed that an increase in NDVI in some buffer zones was associated with reduced risks of hypercholesterolemia, hypertriglyceridemia, low HDL-C, and high LDL-C, while an increase in NDVI in 100m buffer zone was significantly associated with reduced risks of all these four diseases, with hypercholesterolemia (OR=0.87, P<0.05), hypertriglyceridemia (OR=0.94, P<0.05), low HDL-C (OR=0.95, P<0.05), and high LDL-C (OR=0.87, P<0.05). Sensitivity analysis suggested that the results of most meta-analyses were robust. Conclusion With the increase in green space near residential areas, the risk of dyslipidemia may decrease.

Objective: To examine the associations of sleep with overweight/obesity and central obesity in adults, so as to provide insights into improving sleep quality and preventing obesity in adults. Methods: Demographics, height, body weight, waist circumstance and sleep status were collected from the Hubei Provincial Surveillance Program for Adult Chronic Diseases and Their Risk Factors in 2020. Subjects' sleep condiction, overweight/obesity and central obesity were descriptively analyzed. The associations of sleep with overweight/obesity and central obesity were examined using a multivariable logistic regression model. Results: A total of 17 789 participants were recruited, with an average age of (56.21±13.05) years, 61.50% women, and mean duration of (7.18±1.56) h/d. There were 7 019 participants with snoring/asphyxia/suffocation (39.46%), 6 108 participants with sleep difficulty (34.34%), 8 064 participants with night waking at least twice (45.33%), 268 participants taking hypnotics (1.51%), and 6 267 participants with early morning awakening and difficulty in sleep again (35.23%), and there were 8 960 participants with overweight/obesity (50.37%) and 6 148 participants with central obesity (34.56%). Multivariable logistic regression analysis showed that sleep duration of <7 h/d (OR=1.081, 95%CI: 1.007-1.159), snoring/asphyxia/suffocation (OR=2.367, 95%CI: 2.222-2.521), and night waking at least twice (OR=1.106, 95%CI: 1.028-1.191) significantly correlated with overweight/obesity, and sleep duration of >8 h/d (OR=0.834, 95%CI: 0.761-0.913), snoring/asphyxia/suffocation (OR=2.153, 95%CI: 2.019-2.297), and night waking at least twice (OR=1.193, 95%CI: 1.105-1.288) were statistically associated with central obesity. Conclusion Sleep duration, snoring/asphyxia/suffocation and night waking are associated with overweight/obesity and central obesity.

Objective: To analyze the clinical and molecular diagnostic status of Fanconi anemia (FA) in China. Methods: The General situation, clinical manifestations and chromosome breakage test and genetic test results of 107 pediatric FA cases registered in the Chinese Blood and Marrow Transplantation Registry Group (CBMTRG) and the Chinese Children Blood and Marrow Transplantation Registry Group (CCBMTRG) from August 2009 to January 2022 were analyzed retrospectively. Children with FANCA gene variants were divided into mild and severe groups based on the type of variant, and Wilcoxon-test was used to compare the phenotypic differences between groups. Results: Of the 176 registered FA patients, 69 (39.2%) cases were excluded due to lack of definitive genetic diagnosis results, and the remaining 107 children from 15 hospitals were included in the study, including 70 males and 37 females. The age at transplantation treatment were 6 (4, 9) years. The enrolled children were involved in 10 pathogenic genes, including 89 cases of FANCA gene, 7 cases of FANCG gene, 3 cases of FANCB gene, 2 cases of FANCE gene and 1 case each of FANCC, FANCD1, FANCD2, FANCF, FANCJ, and FANCN gene. Compound heterozygous or homozygous of loss-of-function variants account for 69.2% (72/104). Loss-of-function variants account for 79.2% (141/178) in FANCA gene variants, and 20.8% (37/178) were large exon deletions. Fifty-five children (51.4%) had chromosome breakage test records, with a positive rate of 81.8% (45/55). There were 172 congenital malformations in 80 children.Café-au-Lait spots (16.3%, 28/172), thumb deformities (16.3%,28/172), polydactyly (13.9%, 24/172), and short stature (12.2%, 21/172) were the most common congenital malformations in Chinese children with FA. No significant difference was found in the number of congenital malformations between children with severe (50 cases) and mild FANCA variants (26 cases) (Z=-1.33, P=0.185). Conclusions: FANCA gene is the main pathogenic gene in children with FA, where the detection of its exon deletion should be strengthened clinically. There were no phenotypic differences among children with different types of FANCA variants. Chromosome break test is helpful to determine the pathogenicity of variants, but its accuracy needs to be improved.

Objective:To investigate the current situation of developmental coordination disorder in preschool children in Taiyuan, providing evidence for developing health strategies for preschool children in this city.Methods:We selected 11 126 preschool children aged 3-5 years from 24 kindergartens in Taiyuan using the cluster random sampling method during November-December 2018. Each preschool child was tested with the developmental coordination disorder questionnaire for young children.Results:The incidence of developmental coordination disorder was 3.4%, and the incidence of suspected developmental coordination disorder was 5.4%, and the incidences of which were higher in boys than in girls ( χ2 = 9.46, P < 0.01). The incidence of developmental coordination disorder decreased with aging ( r = -0.06, P < 0.01). The incidence of developmental coordination disorder was negatively correlated with parents' education level and maternal passive smoking during pregnancy ( r = -0.11, P < 0.01; r = -0.12, P < 0.01; r = -0.03, P < 0.01). Lower parents' education level and maternal passive smoking during pregnancy led to a higher incidence of developmental coordination disorder in children. Conclusion:Preschool children from Taiyuan had a lower incidence of developmental coordination disorder than those from economically developed south areas. The higher the gross domestic product in the areas where the kindergartens locate, the lower the incidence of developmental coordination disorder ( r = 0.03, P < 0.01). Environmental factors have a certain impact on developmental coordination disorders in preschool children. Parents, kindergarten teachers, and child health workers should take active intervention measures against the adverse factors in the early development environment of children.

Objective:To evaluate the effect of blunt separation method on peripherally inserted central venous catheters.Methods:The randomized controlled trials regard to the effect of blunt separation method on peripheral central venous catheters were retrieved from CNKI, Wan fang Data Knowledge Service Platform, CQVIP, CBM, Cochrane, PubMed, EMBASE and Web of science from January 2010 to March 2021, two researchers performed quality assessments and extracted data according to Cochrane evaluation manual standards. RevMan 5. 4 software was used for statistical analysis.Results:A total of 11 randomized controlled trials were analyzed, including 1379 participants. The meta-analysis results showed that there was no statistical difference in the successful rate of one-time sheath delivery ( OR=1.62, 95% CI 0.92-2.86, P>0.05). However, patients in blunt separation group showed lower blood loss ( OR=0.24, 95% CI 0.11-0.50, P<0.05), lower the incidence of seepage at puncture site ( OR=0.18, 95% CI 0.09-0.37, P<0.05) than those in traditional skin expansion group at 24h after catheterization, and less the time of maintenance within 7 days after catheterization ( MD=-0.95, 95% CI-1.78--0.11, respectively, P<0.05). Conclusions:Blunt separation method can significantly reduce the incidence of complications and the time of catheter maintenance. Due to the limited quality of included studies, more high quality studies are needed to verify the conclusions.

Objective:To explore sex and rural-urban differences in the associations of different blood pressure levels with the risk of prediabetes.Methods:We used a multi-stage stratified cluster random sampling method to investigate 21 637 residents aged ≥18 years from 10 survey areas in Hubei province in 2020. The data on questionnaire, physical measurements, and laboratory indicators of the participants were collected. The associations of different blood pressure levels with risk of prediabetes by sex and regions were analyzed using multivariate logistic regressions after complex weighting.Results:A total of 16 111 subjects were included. The prevalence (95% CI) of prediabetes, impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and IFG complicated with IGT were 25.1% (14.4%-35.9%), 12.7% (3.2%-22.1%), 8.1% (6.3%-9.8%), and 4.4% (2.3%-6.5%), respectively. After multivariate adjustment, the risk of prediabetes, IFG, IGT, and IFG complicated with IGT increased with the increment of blood pressure (both P for trend <0.05). The positive dose-response relationships between blood pressure levels and risk of prediabetes were also significant among male, urban, and rural residents (both P for trend <0.05), and the interactions between sex and blood pressure showed significant associations for risk of prediabetes and IGT (both P for interaction <0.05). Conclusions:Higher blood pressure levels were associated with an increased risk of prediabetes. The association with prediabetes was stronger in males, but no significant difference was found between urban and rural residents. More distinctive and effective prevention and control strategies should be developed for different populations.

Objective:To summarize the relationship between the clinicopathological features and prognosis of immunoglobulin A nephropathy (IgAN) after renal transplantation.Methods:A total of 34 patients with IgAN after renal transplantation confirmed by renal biopsy were enrolled. And another 34 patients with primary IgAN confirmed by initial renal biopsy were adopted as controls. Clinical and pathological features of two groups were compared to explore the relationship between clinicopathological features and prognosis of allograft IgAN.Results:As compared with primary IgAN group, renal function in allograft IgAN group included serum creatinine [(158.5±75.9) vs (84.8±26.8) umol/L], urea nitrogen [(9.7±6.1) vs (5.2±1.4) mmol/L], uric acid [(406.7±87.8) vs (359.0±92.6) umol/L], estimated glomerular filtration rate {(57.4±25.4) vs (91.2±28.6) [ml/(min·1.73m 2)]}. All were statistically significantly higher ( P<0.05) while other parameters showed no differences. Pathologically, the proportion of T1 type (50.0% vs 17.6%) of renal tubular atrophy/interstitial fibrosis was significantly higher in allograft IgAN group than control group ( P<0.05). Furthermore, univariate and multivariate Logistic regression analyses were performed between various pathological parameters and prognosis in allograft IgAN patients. It indicated that the degree of mesangial hyperplasia of patients with transplanted IgAN had a significantly negative impact on the prognosis. Conclusions:The clinicopathological features of patients with allograft IgAN show no difference from those of patients with primary IgAN. And among patients with allograft IgAN, those with severe mesangial hyperplasia often have a worse prognosis.

A 25-year-old man with extensive burn due to industrial dust explosion was admitted to the First Affiliated Hospital of Naval Medical University on 16th October, 2018. Four days after the first skin grafting and vacuum sealing drainage surgery, the patient developed signs of uncontrolled severe inflammation and shock. However, several atypical manifestations interfered the diagnosis of septic shock. After giving emergency treatment including fluid resuscitation, broad-spectrum antibiotics, and administration of vasopressor agents, the patient′s condition was alleviated, but quickly relapsed and deteriorated, with acute pulmonary edema appeared in the evening of the same day. Finally, the condition was reversed by completely removing the negative pressure devices on upper limbs and thorough dressing change. This case suggests that the diagnosis and treatment of infection in patients with extensive burn need comprehensive analysis. Timely intervention of the wound is the key to control the exacerbation of sepsis. In addition, the possibility of pulmonary edema in patients with sepsis should be on high alert.

OBJECTIVETo investigate the therapeutic efficacy of allogeneic peripheral blood hematopoietic stem cell transpdantation (allo-HSCT) for T lymphoblastic lymphoma (T-LBL).

METHODSThe clinical data of 14 adult patients with T-LBL treated with allo-HSCT were collected, the hematopoietic reconstruction, survival and relapse, as well as overall survival (OS) rate, event-free survival (EFS) rate of 1, 3 and 5 years were analysed retrospectively.

RESULTSAll the patients were engrafted with neutrophil successfully, the median time of absolute neutrophil count >0.5 × 10(9)/L was 13 (10-19) d; 13 patients were engrafted with platelets successfully, the median time of Plt count >20 × 10(9)/L was 17 (12-62) days. The acute GVHD occurred in 6 patients, but among them only 1 case with 3 grade of aGVHD; out of 14 patients, 5 developed chronic GVHD. The transplant-related mortality at 100 days was 7.1% (1/14), mainly from coronary heart disease and pulmonary infection. The median follow-up time was 26.5 months, the estimated 1, 3 and 5 year OS rate was 85.7%, 47.6% and 38.1%, respectively, and estimated 1, 3 year EFS rate was 85.7%, 34.4% and 34.1%, respectively. The relapse rate was 42.8% (6/14) and the median relapse time was 22.5% months after transplantation. Up to now, 7 patients still survive, 1 patient out of them have survived for 103 months.

CONCLUSIONThe allo-HSCT is a safe and effective method for treatment of T-LBL.

This study was aimed to investigate the effect of intercellular adhesion molecule-1 (ICAM-1) on the migration in vitro of the murine mesenchymal stem cells (MSC) and its related mechanisms. The migration ability of murine MSC (C3H10T1/2), ICAM-1 transfected MSC (C3H10T1/2-MIGR1-ICAM-1) and empty vector-transfected MSC (C3H10T 1/2-MIGR1) were assayed in vitro by using the transwell system. Briefly, the cells were seeded on the membrane with 8 µm aperture and the fetal bovine serum was used as the chemotactic agent to induce MSC migration. The transmigrated cells were stained by crystal purple as well as DAPI for 8 h and 12 h respectively. The absolute cell numbers were counted and the migration rates of MSC were evaluated in each group. To explore the potential mechanisms which control the migration of MSC, the specific chemical inhibitors of MAPK pathway (SB203580, PD98059 and JNK inhibitor II) were added to the transwell system and the alteration of the MSC migration ability were evaluated at 12 h. The results showed that the migration ability at 8 h and 12 h of the ICAM-1-transfected MSC increased. Both absolute cell number and migration rate of MSC were significantly up-regulated by ICAM-1. Furthermore, the promoting effect of ICAM-1 on migration was partially suppressed by the inhibition of JNK/SAPK pathway. The transmigrated cell numbers and the migration rate decreased with the addition of JNK inhibitor II. However, the ICAM-1 promoting migration of MSC was not suppressed by the inhibitors for ERK/MAPK and p38/MAPK pathway did not work in the present study. It is concluded that ICAM-1 can induce mouse MSC migration in vitro, and the promoting effect is partially dependent on the activation of JNK/SAPK pathway.
