RESUMEN
BACKGROUND:microRNA-26b(miR-26b)plays an important regulatory role in a variety of stem cell functions,but its effects on the biological properties of stem cells from human exfoliated deciduous teeth and human umbilical cord mesenchymal stem cells are unknown. OBJECTIVE:To investigate the effects of miR-26b on the proliferation,migration and osteogenic differentiation of stem cells from human exfoliated deciduous teeth and human umbilical cord mesenchymal stem cells. METHODS:Stem cells from human exfoliated deciduous teeth and human umbilical cord mesenchymal stem cells were cultured and identified.miR-26 mimics(experimental group)and miRNAs mimics control(control group)were used to transfect above mentioned two kinds of cells and construct overexpressed models for subsequent experiments.CCK-8 assay was applied to detect the proliferation ability of overexpressed miR-26b cells.Transwell and scratch assay were employed to analyze the migration ability of overexpressed miR-26b cells.RT-qPCR was utilized to examine the expression of osteogenic markers after osteogenic induction of overexpressed miR-26b cells. RESULTS AND CONCLUSION:(1)Transfection of miR-26b mimics increased miR-26b expression in the two kinds of cells and promoted the proliferation of stem cells from human exfoliated deciduous teeth,with no significant effect on the amplification of human umbilical cord mesenchymal stem cells.(2)Compared with the control group,the migration ability was enhanced after two types of cells overexpressing miR-26b.(3)miR-26b expression decreased during osteogenic differentiation of the two kinds of cells.(4)Compared with the control group,the levels of osteogenesis-related genes osteocalcin,osteopontin,alkaline phosphatase,and human type I collagen mRNA were downregulated after overexpression of miR-26b in the two kinds of cells.The results showed that overexpression of miR-26b promoted the proliferation and migration of stem cells from human exfoliated deciduous teeth and inhibited their osteogenic differentiation;it promoted the migration of human umbilical cord mesenchymal stem cells and inhibited their osteogenic differentiation,but had no significant effects on their proliferation.
RESUMEN
Objective:To evaluate and compare the efficacy and safety of ultra-rapid lispro insulin (URLi) and humalog lispro (HL) in the treatment of type 2 diabetes mellitus.Methods:This was an international multicenter, double-blind, randomized controlled study. From May 2019 to January 2021, a total of 481 patients with type 2 diabetes mellitus, who had been using insulin for at least 90 days and had poor glycemic control, were included. These patients were recruited from 34 research centers in China, including Shanghai Jiao Tong University School of Medicine Affiliated Sixth People′s Hospital. They were assigned to either the URLi group (319 patients) or the HL group (162 patients) using stratified blocked randomization. The primary endpoint was the change in hemoglobin A 1c (HbA 1c) relative to baseline after 26 weeks of treatment. Secondary endpoints included the proportion of patients who achieved HbA 1c<7.0% and ≤6.5% after 26 weeks of treatment, 1-h postprandial glucose (1hPG) or 2-h postprandial glucose (2hPG) excursions during a mixed meal tolerance test at week 26, as well as safety parameters. Continuous variables were compared using mixed model repeated measures or analysis of covariance, and categorical variables were compared using logistic regression or Fisher′s exact test. Results:Data based on the Chinese subgroup showed that there were no statistically significant differences between the URLi and HL groups in terms of male percentage [56.1% (179/319) vs. 56.2% (91/162); P=0.990], age [(59.5±8.4) vs. (59.6±9.3) years; P=0.839] and other baseline characteristics. Regarding the change in HbA 1c relative to baseline, the URLi group was non-inferior to the HL group (-0.59%±0.05% vs. -0.66%±0.06%; P=0.312). There were no statistically significant differences between the URLi and HL groups in proportion of patients who achieved HbA 1c<7.0% [47.3% (138/292) vs. 45.2% (70/155); P=0.907] and≤6.5% [27.7% (81/292) vs. 27.7% (43/155); P=0.816]. The excursions in 1hPG [(6.20±0.21) vs. (6.90±0.25) mmol/L; P=0.001] and 2hPG [(8.10±0.27) vs. (9.30±0.31) mmol/L; P<0.001] were lower in the URLi group than the HL group, with statistically significant differences. In terms of safety, there were no statistically significant differences in the percentage of subjects who reported treatment-emergent adverse events between the URLi and HL groups [49.8% (159/319) vs. 50.0% (81/162); P=1.000]. The event rate of nocturnal hypoglycemia was lower in the URLi group than the HL group, with statistically significant differences [(0.53±0.10) vs. (0.89±0.16) events per patient -year; P=0.040]. Conclusions:With good glycemic control, URLi showed non-inferiority for HbA 1c improvement versus HL and was superior to HL for postprandial glucose excursion control. Meanwhile the rate and incidence of nocturnal hypoglycemia were lower in the URLi group than the HL group.
RESUMEN
Objective To investigate the awareness of malaria-related knowledge, the use of mosquito nets and their influencing factors among residents in Banlao Township, Cangyuan County, Yunnan Province.. Methods In August 2020, 19 settlement sites in Banlao Township, Cangyuan County, Lincang City, Yunnan Province were selected as study areas, and permanent residents at ages of 10 years and older were enrolled for a questionnaire survey, including residents’ demographics, family economic status, malaria control knowledge and use of mosquito nets. In addition, the factors affecting the use of mosquito nets in the night prior to the survey were identified using multivariate logistic regression analysis. Results A total of 320 questionnaires were allocated, and all were recovered (a 100% recovery rate). There were 316 valid questionnaires, with an effective recovery rate of 98.75%. The 316 respondents included 152 men and 164 women and 250 Chinese respondents and 66 foreign respondents. The awareness of clinical syndromes of malaria was significantly higher among Chinese residents (71.60%) than among foreign residents (50.00%) (χ2 = 11.03, P < 0.01), and the proportions of Chinese and foreign residents sleeping under mosquito nets were 46.00% and 69.70% on the night prior to the survey, respectively (χ2 = 11.73, P < 0.01). Multivariate logistic regression analysis identified ethnicity group and type of residence as factors affecting the use of mosquito nets in the night prior to the survey. Conclusions The awareness of malaria control knowledge, the coverage and the use of mosquito nets were low among residents in Banlao Township, Cangyuan County, Yunnan Province. Targeted health education is recommended to improve the awareness of malaria control knowledge and self-protection ability. In addition, improving the allocation of long-lasting mosquito nets and health education pertaining to their uses and increasing the proportion of using mosquito nets correctly is needed to prevent re-establishment of imported malaria.

RESUMEN
Objective:To investigate the clinical, genetic, and pathological features of nemaline myopathy type 8 (NEM8) caused by KLHL40 gene variation. Methods:The clinical data, gene sequencing results, and musculoskeletal pathophysiology of two cases (a pair of twins) with NEM8 admitted to our hospital in July 2022 were collected. CNKI, VIP, Wanfang, Yiigle, PubMed, Embase, and Web of Science Database were searched with the English and Chinese terms "nemaline myopathy type 8", "nemaline body myopathy type 8", and " KLHL40" from January 2007 to February 2023. The clinical, genetic, and musculoskeletal characteristics of the NEM8 cases were summarized using the descriptive statistical analysis method. Results:(1) Case report: The mother (G2P2) of the twins (Ⅳ-2 and Ⅳ-3) was conceived by IVF-embryo transfer and delivered at 37 +1 gestational weeks. The two cases were dizygotic twins whose maternal grandmother had lip and palate cleft. The first baby (Ⅳ-1) of the woman exhibited absent left pinna, contracture at the end of both fingers, talipes equinovarus in both feet and died of respiratory failure two hours after birth. Fetal edema and fetal movement delay in the twins and varus right foot in one twin were found during pregnancy. Both cases developed intrapartum asphyxia with the clinical manifestations of generalized muscle weakness, respiratory failure, dysphagia, multiple joint contractures, and fractures. The families withdrew the treatment and the twins died after maintaining life with ventilators for 53 days after birth. Whole exome sequencing of the pedigree found c.1779G>T (p.W593C) homozygous variants of the KLHL40 gene in the twins and c.1779G>T (p.W593C) heterozygous variants of the KLHL40 gene in the parents, both were de novo. Musculoskeletal pathophysiology indicated that muscle fibers are thin and round with a fetal shape and absent rod. (2) Literature review: Among the 29 cases of NEM8, including two current cases and 27 cases retrieved from 15 papers, eight cases terminated the pregnancies, and 21 were live births; seven cases (24.1%) with positive family history; 19 cases (65.5%) were found with abnormalities during pregnancy, including abnormal fetal movements, polyhydramnios, joint contracture, and fetal edema. Of the 21 live births, 20 cases had intrapartum asphyxia, 21 had postnatal respiratory failure, 20 had generalized muscle weakness, and 19 had dysphagia. Among the 29 cases, 17 cases (58.6%) were homozygous variants of the KLHL40 gene, and 12 cases (41.4%) were compound heterozygous variants. The detection rate of c.1516A>C(p.Thr506Pro) was the highest [72.4% (21/29)], followed by c.602G>A(p.Trp201*) [17.2% (5/29)]. Out of the 15 cases who underwent musculoskeletal pathological examination, all had abnormal muscle fiber size and morphology; 10 cases had rods. Conclusions:NEM8 should be considered for those with abnormal fetal movements, polyhydramnios, joint malformation, fetal edema during the fetal period and failure to establish respiration at birth as well as postnatal generalized muscle weakness, respiratory failure, dysphagia, multiple joint contractures, and fracture. Moreover, genetic detection should be performed as soon as possible. NEM8 can be diagnosed in ones with KLHL40 gene homozygous or compound heterozygous variants and musculoskeletal pathological results of abnormal size and shape of muscle fibers, regardless of the presence of rods.

Objective:To study the feasibility, safety and effectiveness of single-port laparoscopic retroperitoneal debridement for infectious necrotizing pancreatitis.Methods:The clinical data of 63 patients with residual infectious stage of infectious necrotizing pancreatitis treated at the Qilu Hospital of Shandong University from October 2012 to August 2017 were retrospectively analyzed. A total of 33 patients who underwent single-port laparoscopic retroperitoneal debridement were classified as the study group, while the remaining 30 patients who underwent traditional open surgery served as the control group.Results:One patient in the study group died 20 days after surgery, while three patients in the control group died after surgery. The operation time, intraoperative blood loss, hospitalization cost, surgical site infection rate, postoperative hospital stay and other parameters in the study group were significantly lower than those in the control group (all P<0.05). There were no significant differences in the incidences of postoperative colon fistula, incisional hernia and gastroparesis between the two groups (all P>0.05). After a follow-up which ranged from 6.0 to 48.0 months, there was no newly diagnosed diabetic patients in the study group, but 2 in the control group. The difference was not significantly different ( P>0.05). Conclusion:Single-port laparoscopic retroperitoneal debridement had the advantages of safety, feasibility and fast postoperative recovery with significant curative effects.
RESUMEN
BACKGROUND@#Mesenchymal stem cell (MSC)-based cell transplantation is an effective means of treating chronic liver injury, fibrosis and end-stage liver disease. However, extensive studies have found that only a small number of transplanted cells migrate to the site of injury or lesion, and repair efficacy is very limited. @*METHODS@#Bone marrow-derived MSCs (BM-MSCs) were generated that overexpressed the erythropoietin (EPO) gene using a lentivirus. Cell Counting Kit-8 was used to detect the viability of BM-MSCs after overexpressing EPO. Cell migration and apoptosis were verified using Boyden chamber and flow cytometry, respectively. Finally, the anti-fibrosis efficacy of EPO-MSCs was evaluated in vivo using immunohistochemical analysis. @*RESULTS@#EPO overexpression promoted cell viability and migration of BM-MSCs without inducing apoptosis, and EPO-MSC treatment significantly alleviated liver fibrosis in a carbon tetrachloride (CCl4 ) induced mouse liver fibrosis model. @*CONCLUSION@#EPO-MSCs enhance anti-fibrotic efficacy, with higher cell viability and stronger migration ability compared with treatment with BM-MSCs only. These findings support improving the efficiency of MSCs transplantation as a potential therapeutic strategy for liver fibrosis.

Participants were divided into four groups according to the quartile of 24 h urinary sodium to potassium ratio.</p><p><b>RESULTS</b>Of the 1 906 Chinese adults eligible for final data analysis, 471 (24.7%) were with MS. After completion of multivariate logistic regression analysis, when compared to the participants with 24 h urinary sodium to potassium ratio < 4.3, the OR (95% CI) of participants with 24 h urinary sodium to potassium ratio during 4.3-5.6, 5.7-8.1, and ≥ 8.1 were 1.27 (0.93-1.71), 1.06 (0.78-1.46), and 1.45 (1.06-1.97), respectively (P values for linear trend < 0.05). As for the components of MS, the odds of central obesity and elevated blood pressure but not the odds of elevated triglycerides, low high density lipoprotein cholesterol and elevated fasting glucose, had significantly increases with successive 24 h urinary sodium to potassium ratio quartiles (P values for linear trends < 0.05).</p><p><b>CONCLUSION</b>The 24 h urinary sodium to potassium ratio appeared significantly associated with the odds of MS.</p>

Obesity is a risk factor for chronic kidney disease, and its prevalence among the elderly is increasing. We investigated the effects of changes in body fat percentage (BFP) on the longitudinal changes in the estimated glomerular filtration rate (eGFR) in the elderly. This prospective cohort study included 390 participants aged >65 years who underwent bioelectrical impedance analysis at baseline and follow-up as a part of the Korean Longitudinal Study on Health and Aging. After a median follow-up period of 5.3 years, BFP was significantly higher than that at the start point (P<0.05). Participants who had the largest increase in BFP had the highest BMI and waist circumference (WC) (P<0.001). The highest tertile had the highest white blood cell count and erythrocyte sedimentation rate, incidence of rapid progression, and decline in eGFR >25% (P≤0.017, Pâ=â0.025, Pâ=â0.005, respectively). The lowest tertile had the lowest triglyceride and highest high-density lipoprotein levels (P<0.05). The adjusted decline rate in eGFR was correlated with a change in BFP (Pâ=â0.039), but not with that in BMI or WC. The highest tertile had a 4.875-fold increase in the risk for rapid progression to a decline in eGFR (95% CI: 1.366-17.397) and a 4.931-fold decrease in the risk to a decline in eGFR>25% (95% CI: 1.617-15.037), when compared with the lowest tertile. In subgroup analysis, the incidence of renal outcomes was significantly increased according to the increase in BFP in patients with lower eGFR (P≤0.010). A change in BFP may be associated with inflammation and dyslipidemia development, and longitudinal changes in body fat are related to a decrease in eGFR in the elderly.
