Relationship between hemoglobin and serum uric acid in adults with various glucose metabolism status / 中华预防医学杂志

Objective: To investigate the relationship between hemoglobin and serum uric acid in adults with various glucose metabolism status. Methods: The demographic data and biochemical indicators of the adult population who had received physical examination in the Second Medical Center of the PLA General Hospital from January 2018 to December 2021 were collected. The subjects were divided into two groups according to the level of serum uric acid: the normal uric acid group and the hyperuricemia group. The relationship between hemoglobin (stratified into four levels of Q1 to Q4 by the quartile) and serum uric acid was quantified by using Pearson correlation and logistic regression analysis. The effects of age and glucose metabolism status on the relationship between hemoglobin and serum uric acid were analyzed. Results: A total of 33 183 adults were enrolled with age (50.6±10.0) years. The level of hemoglobin in the normal uric acid group (142.61±14.24) g/L was significantly lower than that in the hyperuricemia group [(151.79±11.24) g/L, P<0.001]. Univariate Pearson correlation analysis showed that hemoglobin was positively associated with serum uric acid (r=0.444, P<0.001). After adjusting for related confounding factors, multivariate logistic regression analysis showed that hemoglobin was associated with serum uric acid, and the OR values (95%CI) of hemoglobin Q2 to Q4 group were 1.29 (1.13-1.48), 1.42 (1.24-1.62) and 1.51 (1.32-1.72), respectively (Ptrend<0.001) when compared with hemoglobin Q1 group. Subgroup analysis and hierarchical interaction analysis suggested that with the increase of hemoglobin, the serum uric acid in the age<60 years subgroup, normal glucose subgroup and prediabetes subgroup increased gradually (Ptrend<0.05 and Pinteraction<0.001). Conclusion: The association between hemoglobin and serum uric acid in adults is affected by age and glucose metabolism status.

Clinical study of double plate system in the treatment of complex proximal humeral fractures in the elderly / 中国骨伤

OBJECTIVE@#To explore the clinical outcomes of anteromedial combined with lateral locking plate for complex proximal humeral fractures in the eldery.@*METHODS@#From June 2018 to October 2020, 30 patients who underwent surgical treatment for Neer grade 3 to 4 proximal humeral fractures, including 8 males and 22 females, aged from 51 to 78 years old with an average of (61.5±7.5) years old. Of them, 15 patients had fractures fixed with anteromedial combined with lateral locking plate(ALLP group), whereas 15 received internal fixation with proximal humerus locking plate only(PHLP group). The clinical data, simple shoulder test (SST), humeral head height loss, varus angle and shoulder range of motion were compared between the two groups.@*RESULTS@#All fractures were healed. The follow-up time ranged from 12 to 24 months, with an average of(14.3±2.9) months. The operation time of ALLP group was longer than that of PHLP group (P<0.05). There was no significant difference in intraoperative blood loss between the two groups (P>0.05). There was no significant difference in SST score between the two groups at 1, 3 and 12 months after operation (P>0.05). In terms of radiographic measurement, there was no significant difference in humeral head height loss and varus angle between the two groups at 1 and 3 months after operation (P>0.05). At 12 months after operation, the height loss and varus angle of humeral head in ALLP group were lower than those in PHLP group (P<0.05). In shoulder range of motion, the range of forward elevation in ALLP group was larger than that in PHLP group 1 year after operation(P<0.05). There was no significant difference in external rotation between the two groups.@*CONCLUSION@#Anteromedial combined with lateral locking plate in the treatment of complex proximal humeral fractures in the elderly can increase the stability of the medial column and obtain a good fracture prognosis. But there are also disadvantages such as longer operation time, so it should be individualized according to the fracture type of the patient.

Application of LASSO and its extended method in variable selection of regression analysis / 中华预防医学杂志

Multicollinearity is an important issue affecting the results of regression analysis. LASSO developed in recent years has great advantages in selecting explanatory variables, processing high-dimensional data, and solving multicollinearity problems. This method adds a penalty term to the model estimation, which can compress the regression coefficients of some unnecessary variables to zero and then remove them from the model to achieve the purpose of variable screening. This paper focuses on the LASSO method and compares it with optimal subsets, ridge regression, adaptive LASSO, and elastic net results. It is found that both LASSO and adaptive LASSO have good performance in solving independent variable multicollinearity problems and enhancing model interpretation and prediction accuracy.

Down-regulation of the Smad signaling by circZBTB46 via the Smad2-PDLIM5 axis to inhibit type I collagen expression / 老年心脏病学杂志（英文版）

BACKGROUND@#Abnormal type I collagen (COL1) expression is associated with the development of many cardiovascular diseases. The TGF-beta/Smad signaling pathway and circRNAs have been shown to regulate COL1 gene expression, but the underlying molecular mechanisms are still not fully understood.@*METHODS@#Gain- and loss-of-function experiments were prformed to study the effect of circZBTB46 on the expression of alpha 2 chain of type I collagen (COL1A2). Co-immunoprecipitation assay was performed to observe the interaction between two proteins. RNA immunoprecipitation assay and biotin pull-down assay were performed to observe the interaction of circZBTB46 with PDLIM5.@*RESULTS@#In this study, we investigated the role of circZBTB46 in regulating COL1A2 expression in human vascular smooth muscle cells (VSMCs). We found that circZBTB46 is expressed in VSMCs and that TGF-beta inhibits circZBTB46 formation by downregulating KLF4 expression through activation of the Smad signaling pathway. CircZBTB46 inhibits the expression of COL1A2 induced by TGF-beta. Mechanistically, circZBTB46 mediates the interaction between Smad2 and PDLIM5, resulting in the inhibition of Smad signaling and the subsequent downregulation of COL1A2 expression. Furthermore, we found that the expression of TGF-beta and COL1A2 is decreased, while circZBTB46 expression is increased in human abdominal aortic aneurysm tissues, indicating that circZBTB46-mediated regulation of TGF-beta/Smad signaling and COL1A2 synthesis in VSMCs plays a crucial role in vascular homeostasis and aneurysm development.@*CONCLUSIONS@#CircZBTB46 was identified as a novel inhibitor of COL1 synthesis in VSMCs, highlighting the importance of circZBTB46 and PDLIM5 in regulating TGF-beta/Smad signaling and COL1A2 expression.

OBJECTIVE@#To explore the therapeutic effect and safety of acupoint thread embedding therapy in treatment of simple obesity of stomach heat and damp obstruction.@*METHODS@#A total of 144 patients with simple obesity of stomach heat and damp obstruction were randomized into an acupoint thread embedding group (72 cases, 3 cases dropped off and 1 case removed) and a sham-embedding group (72 cases, 6 cases dropped off and 3 cases removed). On the base of the lifestyle adjustment, the acupoint thread embedding therapy with PGLA thread was applied to Tianshu (ST 25), Zhongwan (CV 12), Ganshu (BL 18), Shuidao (ST 28), etc. in the acupoint thread embedding group, while in the sham-embedding group, the acupoint selection and operation were all same as the acupoint thread embedding group, but without PGLA thread embedded. In either group, the treatment was given once every 2 weeks, consecutively for 12 weeks and the follow-up was conducted for 3 months after treatment. Separately, before and after treatment as well as in follow-up, the obesity indices (body mass index [BMI], waist circumference [WC], waist-to-hip ratio [WHR] and fat percentage [F%]) were observed in the two groups. Before and after treatment, the indices of blood glucose and insulin (fasting blood glucose [FBG], fasting insulin [FINS] and insulin resistance index [HOMA-IR]), adipocyte factor indices (adiponectin, leptin [LP] and serine protease inhibitor [Vaspin]) and inflammatory factor indices (tumor nercosis factor [TNF-α], interleukin-1β [IL-1β] and interleukin-6 [IL-6]) were observed separately in the two groups. The therapeutic effect and safety were compared between the two groups.@*RESULTS@#After treatment and in follow-up, except WC and WHR in the sham-embedding group, BMI, WC, WHR and F% were all reduced as compared with those before treatment in the two groups (P<0.01, P<0.05), and the values in the acupoint thread embedding group were lower than the sham-embedding group (P<0.01). After treatment, except FBG, LP and Vaspin in the sham-embedding group, FBG, FINS, HOMA-IR, LP and Vaspin were all reduced as compared with those before treatment in the two groups (P<0.01, P<0.05), and adiponectin was increased as compared with that before treatment (P<0.01, P<0.05); the improvements in the acupoint thread embedding group were more significant than the sham-embedding group (P<0.01). After treatment, the levels of serum TNF-α, IL-1β and IL-6 in the acupoint thread embedding group were reduced as compared with the values before treatment and those in the sham-embedding group separately (P<0.01). The total effective rate was 89.7% (61/68) in the acupoint thread embedding group, higher than 19.0% (12/63) in the sham-embedding group (P<0.01). There was no severe adverse reaction reported in the two groups.@*CONCLUSION@#Acupoint thread embedding therapy with PGLA thread can alleviate obesity, regulate glucose metabolism and adipocyte factors activity, improve insulin resistance and inhibit the expression of pro-inflammatory factors in the patients with simple obesity with stomach heat and damp obstruction, and this therapy presents a satisfactory safety in treatment.

A comparative study of sagittal spinal-pelvic parameters between patients with adolescent idiopathic scoliosis and healthy controls / Un estudio comparativo de los parámetros sagitales de la columna vertebral-pélvic entre pacientes adolescentes con escoliosis idiopática y controles sanos

This study aimed to investigate the sagittal spinal-pelvic morphological changes, as well as the relationship between pelvic anatomical changes and the spinal-pelvic plane in patients with adolescent idiopathic scoliosis (AIS), in order to provide guidelines for orthopedic surgery in AIS. X-ray data were collected for retrospective analysis from 30 patients diagnosed as AIS in the Departments of Radiology at the Second Affiliated Hospital of Inner Mongolia Medical University and the Inner Mongolia International Mongolian Medical Hospital from April 2014 to November 2018, along with 30 normal adolescents as control. Pelvic parameters, including pelvic incidence (PI), pelvic tilt (PT), and sacral slope (SS), a spinal parameter, lumbar lordosis (LL), and anatomical parameters, including sacral width (SW) and femoral head- sacrum distance (FH-S), were measured. The spinal-pelvic parameters were compared between AIS patients and normal controls and also between male and female AIS patients. Pearson correlation was performed to analyze correlation between spinal-pelvic parameters and between spinal-pelvic parameters and anatomical parameters in both AIS patients and normal controls. PT was significantly lower in AIS patients than in normal controls (P < 0.05), whereas no significant difference was found in the other spinal-pelvic parameters, i. e. , LL, PI, and SS. There was a significant difference in PT between sexes in AIS patients. SS was significantly correlated with LL in EIA patients (P < 0.05, r > 0.5). SS was significantly correlated with LL and PI, and PT with LL, PI, and SS in normal controls (all P < 0.05), and there was no significant correlation between the other sagittal spinal-pelvic parameters (P > 0.05). FH-S was significantly correlated with LL, PI, SS, and PT in AIS patients (all P < 0.05). AIS affects some of the sagittal spinalpelvic parameters and anatomical parameters. In AIS, there is a significant correlation between the spinal-pelvic parameters, and the anatomical parameter is significantly correlated with multiple spinal-pelvic parameters.

Hubo una diferencia significativa en PT en pacientes de ambos sexos con EIA. SS se correlacionó significativamente con LL en pacientes con EIA (P <0,05, r> 0,5). SS se correlacionó significativamente con LL y PI, y PT con LL, PI y SS en controles normales (todos P <0,05), y no hubo correlación significativa entre los otros parámetros sagitales de la columna vertebral-pélvica (P> 0,05) FH-S se correlacionó significativamente con LL, PI, SS y PT en pacientes con EIA (todos P <0,05). EIA afecta algunos de los parámetros sagitales de la columna vertebral-pélvica y los parámetros anatómicos. En EIA, existe una correlación significativa entre los parámetros espinal-pélvicos, y el parámetro anatómico se correlaciona significativamente con múltiples parámetros espinales-pélvicos.

Widespread use of anti-retroviral therapy elevated the prevalence of dyslipidemia in HIV-infected Chinese patients

With the widespread use of high-efficiency antiretroviral therapy (HAART), the life expectancy of HIV-infected patients has been significantly extended. However, the metabolic complications among HIV-infected patients treated with HAART have become the most common problem in the world. It is very important to explore the incidence of dyslipidaemia and studies on the role of potential risk factors in HIV-infected Chinese patients treated with HAART are sparse. Therefore, we designed current study, to investigate the effects of therapeutic intervention and continuous information support on the lifestyle of HIV/AIDS patients with dyslipidaemia. Three hundred and six HIV/AIDS patients admitted to the AIDS clinic in Beijing from January 2016 to January 2017 were recruited and assigned into two groups: the treatment group (n=64) and the control group (n=64). The median age of the participants was 38.8±11.0 years (range 20-75 years). The prevalence of dyslipidemia in control and treatment group was (59/64) 92.2% and (53/64) 82.8%, respectively. In this study, low HDL-cholesterol (HDLC) led to abnormalities 47/64 (73.3%) in the control group and 35/64 (54.7%) in HAART-treatment group. Additionally, HAART group showed higher triglyceride, total cholesterol, and low-density lipoprotein (246.1±171.8, 1.73±1.61 mmol/L, 4.46±1.1 mmol/L, 2.54±0.74 mmol/L). In multivariate analysis, gender, marital status, high BMI, dietary habits and physical activity were potential risk factors for dyslipidemia in HIV-infected Chinese patients. In this study, we reported high prevalence dyslipidemiain two HIV infected groups. We suggest that the appropriate diagnosis should be performed for analyzing the metabolic complications in HIV-infected Chinese patients. Further studies are very important to understand the role of potential risk factors in metabolic complications.

OBJECTIVE@#To evaluate the clinical characteristics, genetic abnormalities, treatment efficacy and prognostic factors in patients with plasma cell leukemia(PCL).@*METHODS@#30 patients diagnosed as PCL in our hospital from January 1993 to December 2019 were enrolled, and the clinical characteristics, laboratory findings, therapeutic regimes, and survival data of the patients were retrospectively analyzed.@*RESULTS@#The median age of the 30 patients was 56.5 (28-80) years old, among them, 25 patients were primary plasma cell leukemia, and 5 patients were secondary plasma cell leukemia. Complex karyotypes and subdiploids were most common in cytogenetic abnormalities. Among the 20 cases of chromosome G banding, 11 (55%) cases were complex karyotypes and 8 (40%) cases were hypodiploid. Fluorescent in situ hybridization (FISH) test showed that among 11 cases, 6 cases showed 17p13 deletion, 8 cases showed at least two kinds of abnormalities, which including t (14; 16), t (8; 14), t (11;14), 17p13 deletion, and 13q14 deletion. The median overall survival (OS) time was 10.5 months for all patients. The median OS time of the patients in ECOG score ≤ 2 group was 21.5 months, which was significantly longer than those in the ECOG score>2 group(1.2 months) (P=0.017). The median OS time of the patients treated with novel agents (including proteasome inhibitor and/or immunomodulator) was 24.9 months, which was significantly longer than the patients treated with traditional chemotherapy group(10.5 months) (P＜0.001). For the patients treated with novel agents, the median OS time of patients accepted two novel agents combination was 30.9 months, which was longer than those of single novel agent(11.5 months) (P=0.021). The effect of genetic abnormolity to the OS of the patients showed no statistical difference. Multivariate statistical analysis showed that ECOG score>2 was the independent prognostic factor of plasma cell leukemia patients. There were two patients underwent allogeneic hematopoietic stem cell transplantation in the study,but died due to the pulmonary infection within 6 months after transplantation.@*CONCLUSION@#In the era of novel agents, ECOG score is an independent prognostic factor of plasma cell leukemia. Multiple novel agents treatment should be underwent as soon as possible to improve the prognosis of the patients. Pulmonary infection is a common factor that cause the death of the patients after allogeneic hematopoietic stem cell transplantation.

Expression of transcription factor FOXP4 in laryngeal squamous cell carcinoma tissues and its effects on biological characteristics of laryngeal squamous cell carcinoma TU177 cells / 中国肿瘤生物治疗杂志

@#[Abstract] Objective:To detect the expression of transcription factor FOXP4 (Forkhead box P4) in laryngeal squamous cell carcinoma (LSCC) tissues and cell lines, and to investigate its effects on the proliferation, migration, invasion, cell cycle, and apoptosis of LSCC TU177 cells in vitro as well as to explore its relationship with epithelial-mesenchymal transition (EMT) process. Methods: A total of 40 pairs of tumor tissues and adjacent tissues that resected from LSCC patients were collected from the biological specimen bank of the Forth Hospital of Hebei Medical University between 2013 and 2015. The expression of FOXP4 in LSCC tissues and corresponding adjacent tissues was detected by qPCR. qPCR and Western blotting were used to detect the FOXP4 expression level in human LSCC cell lines (AMC-HN-8, TU177, TU686, and TU212). Small interfering RNA (si-RNA) was used to knock down FOXP4 expression in TU177 cells. The effects of FOXP4 knockdown on the proliferation, migration, invasion, cell cycle and apoptosis of TU177 cells were measured by MTS assay, clone formation assay, Transwell chamber migration and invasion assay, and flow cytometry, respectively. The mRNA levels of EMT markers N-cadherin, β-catenin, Vimentin, Twist, Snail and zine finger E box binding homeobox 1 (ZEB1) after transfection of si-FOXP4 in TU177 cells were detected by qPCR. The changes of protein levels of N-cadherin, β-catenin, Vimentin and Twist after FOXP4 knockdown were measured by Western blotting. Results: The expression of FOXP4 in LSCC tissues was significantly higher than that in adjacent tissues (P<0.05), and it was related to the TNM stage of tumors and lymph node metastasis (all P<0.05). The expression of FOXP4 in LSCC cells was higher than that in the adjacent tissues (P<0.05 or P<0.01). The expression of FOXP4 in TU177 cells transfected with si-FOXP4 was significantly lower than that in the control group (P<0.01). Compared with the control group, knocking down FOXP4 could inhibit the proliferation, migration and invasion but promote the apoptosis of TU177 cells in vitro (all P<0.01), block the cell cycle at G0/G1 phase (P<0.01), and reduce cell replication in S phase (P<0.01); in addition, knocking down FOXP4 could reduce the mRNA levels of N-cadherin, β-catenin, Vimentin, Twist, Snail, ZEB1 (P<0.05 or P<0.01) and the protein levels of N-cadherin, β-catenin, Vimentin, Twist in TU177 cells. Conclusion: The high expression of FOXP4 may be related to the occurrence and development of LSCC. FOXP4 knockdown can inhibit the proliferation, migration and invasion of laryngeal cancer cells in vitro, block cell cycle at G0/G1 phase, promote apoptosis, and may participate in the EMT process.

Ophiopogonin D upregulates CYP2J3/EETs to activate PI3K/Akt-eNOS pathway and rescue H2O2-induced H9c2 cell injury / 中国药理学与毒理学杂志

OBJECTIVE To explore the protective effect and mechanism of ophiopogonin D (OP-D) on oxidative stress injury of H9c2 cells induced by H2O2. METHODS An oxidative damage model of H9c2 cells was established by H2O2 induction. The cells were divided into control group (cultured in serum-free medium for 28 h), H2O2 injury model group (treated with H2O2400μmol·L-1 for 3 h), OP-D 5, 10 and 20 μmol · L-1 pretreatment groups (treated with H2O2400 μmol · L-1 for 3 h after OP-D pretreat?ment for 24 h), and an inhibitor of CYP2J3, 6-(2-proparglyloxyphenyl) hexanoic acid (PPOH) group (OP-D 20μmol·L-1+PPOH 10μmol·L-1, PPOH was added to the cells 1 h before OP-D treatment). Cell activity was measured by MTT method, levels of dihydroxyeicosatrienoic acid (11,12-DHET and 14,15-DHET respectively) were detected by enzyme-linked immunosorbent assay (ELISA), while levels of malondialdehyde (MDA), nitric oxide (NO) and activity of lactate dehydrogenase (LDH), superoxide dismutase (SOD) were detected by assay kits. Flow cytometry (FCM) was used to detect reactive oxygen species (ROS) and apoptosis. Western blotting was used to detect the expressions of CYP2J3, Akt phos?phorylation (p-Akt) protein and endothelial nitric oxide synthase phosphorylation (p-eNOS) protein in cells, and the possible mechanism by which OP-D reduces oxidative stress was further verified with PPOH. RESULTS H2O2400μmol · L-1 significantly inhibited H9c2 cell viability (P<0.01), and OP-D signifi?cantly increased the cell survival rate after H2O2 injury (P<0.01). Different concentrations of OP-D increased the level of 11,12- DHET and 14,15-DHET (P<0.05, P<0.01). OP-D increased the level of NO in cells after H2O2-induced injury (P<0.05, P<0.01), enhanced the activity of SOD (P<0.05), and decreased the level of MDA and LDH (P<0.05, P<0.01). OP-D significantly reduced oxidative stress and apoptosis after H2O2 injury (P<0.05, P<0.01). OP-D pretreatment increased the protein and mRNA expression of CYP2J3 (P<0.05, P<0.01) and the phosphorylation of PI3K/Akt-eNOS pathway after H2O2 injury (P<0.05, P<0.01). After PPOH was given in advance, the protective effect of OP-D was inhibited (P<0.05, P<0.01). CONCLUSION OP-D can reduce H2O2-induced H9c2 cell damage, which may be related to the activation of PI3K pathway and the phosphorylation of its downstream factors Akt and eNOS by inducing CYP2J3 expression and increasing the contents of 11,12-DHET and 14,15-DHET.

Perioperative management of new-onset atrial fibrillation after cardiac surgery / 中国胸心血管外科临床杂志

@#New-onset atrial fibrillation (NOAF) is the most common complication after cardiac surgery. Postoperative atrial fibrillation is traditionally believed to a benign arrhythmia secondary to inflammation or surgical stimulation. However, a number of studies showed that patients with NOAF had a substantially increased adverse cardiovascular events. Therefore, effective treatment is of great significance. This study aims to review recent research of the perioperative management of NOAF.
