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.

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.

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.

Aim To elucidate the molecular mechanism of Sophora tonkinensis Gagnep in improving acute pharyngitis based on network pharmacology, animal experiments and quantitative real-time PCR.Methods The active components and targets of Sophora tonkinensis Gagnep were collected from the database of traditional Chinese medicinal systems databases and analysis platform(TCMSP). Targets related to acute pharyngitis were acquired through GeneCards, OMIM, DrugBank and Disgenet databases. After the common targets of the two were screened, the STRING database was used to construct the protein interaction network, and the Metascape platform was used for pathway analysis. At the same time, Cytoscape software was used to construct a network of "herbal-disease-component-target" and "herbal-disease-component-target-pathway" network. The acute pharyngitis models in rats were established to study the effect of water extract of Sophora tonkinensis Gagnep on acute pharyngitis in rats. Quantitative real-time PCR technology was used to study the effect of Sophora tonkinensis Gagnep on key gene targets in key pathways of pharyngeal tissues in rats with acute pharyngitis. Results In this experiment, 509 related targets of 21 active components of Sophora tonkinensis Gagnep were obtained, 2 167 related targets of acute pharyngitis were obtained, and 194 common targets of Sophora tonkinensis Gagnep and acute pharyngitis were obtained. KEGG pathway analysis screened 344 related signaling pathways, indicating that IL-17 signaling pathway, NF-kappa B signaling pathway and leukocyte transendothelial migration pathway might play a key role in the improvement of acute pharyngitis by Sophorae tonkinensis Gagnep. Animal experiments showed that the low dose group of Sophora tonkinensis Gagnep water extract had better therapeutic effect on acute pharyngitis. The results of quantitative real-time PCR showed that the low-dose group of Sophora tonkinensis Gagnep significantly down-regulated the expression levels of ITGB2, PIK3CA, PIK3CD and PTPN11 genes in leukocyte transendothelial migration pathway(P<0.05). Conclusions The above results show that Sophora tonkinensis Gagnep has the characteristics of multi-component, multi-target and multi-pathway synergy in improving acute pharyngitis, which provides a theoretical basis for further study on the complex mechanism of Sophora tonkinensis Gagnep in improving acute pharyngitis.

@#Abstract: Cell death is a fundamental biological phenomenon that is essential for the survival and development of organisms. Cell death can be either a spontaneous programmed process by the host or an accidentally triggered process. According to the different signaling pathway activated by various stimulates, programmed cell death exhibits the lytic or non-lytic morphology. For example, apoptosis, a typical non-lytic form of cell death, exhibits cell shrinkage and induces the formation of apoptotic bodies. Pyroptosis mediated by cysteine-containing aspartate-specific protease-1/11 (caspase-1/11) and necroptosis can induce inflammatory reactions and promote cell lysis to release inflammatory cytokines via triggering the pore-forming mechanism of the cell membrane, representing a typical modes of lytic cell death. In addition, the release of reactive oxygen species caused by the damaged mitochondria may further trigger ferroptosis during the pathogen infection. Programmed cell death can play an immune defensive role by eliminating infected cells and intracellular pathogens and stimulating the innate immune response through the resulting cell corpses. Here, we discuss the molecular mechanisms of five programmed cell death pathways: apoptosis, pyroptosis, ferroptosis, necroptosis and PANoptosis. We describe their roles in the innate immune defense against bacterial infections and give a brief statement of the interactions between the different programmed cell death, hoping to provide new insights for in-depth study of the pathogenic mechanisms of infectious diseases.

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.

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.

Ischemic dysfunction is an important global health problem. Vascular endothelial cells(VECs) play a key role in angiogenesis, and insufficient vascular remodeling may lead to chronic nonhealing wounds. Therefore, effective VEC generation strategies of exploration help improve angiogenesisin damaged tissues. Embryonic stem cells (ESCs) are widely used in the study of tissueendothelialization, and endothelial progenitor cells (EPCs) are indispensable parts of the development ofVECs. The aims of this study were to find a rapid, easily screened and reproducible method for thederivation of EPCs from mouse embryonic stem cells (mESCs), and obtain VECs with high survival ratesand strong functions from the directed differentiation of the EPCs. The results showed that mESCs weredifferentiated into " stepping stone" -like progenitor cells with active proliferative ability by 10 ng / mLVEGF and 5 ng / mL bFGF. At the same time, the method of differential adherence was helpful for theselection of EPCs, and EPCs induced high expression of CD133 and CD34 (The relative expressionlevels were 0. 88 ± 0. 04 and 2. 12 ± 0. 02, respectively) for 3 days. Then EPCs were digested withacctuse enzymes, and induced to differentiate into vascular endothelial-like cells by 50 ng / mL VEGF and25 ng / mL bFGF for 7 days. The endothelial cells not only expressed endothelial marker genes (CD31, CD144, LAMA5, Tek, KDR and vWF),and marker proteins CD31, CD144 and LAMA5 (The relativeexpression levels were 1. 07 ± 0. 03, 0. 60 ± 0. 02 and 0. 70 ± 0. 02, respectively), but also had thegood ability of migration, tubulogenesis and formation of W-P bodies. Moreover, PBS, EPC and VECwere used to treat wounds of the same size. Both EPC and VEC could accelerate the degree of tissuehealing (The relative healing rates were 78. 93 ± 75. 35%, 95. 57 ± 83. 73% and 100. 00 ± 0. 00%, respectively), and VEC significantly enhanced the ability of wound angiogenesis and inflammatoryresponses. In consequence, this study preliminarily confirmed that mESC-derived EPCs coulddifferentiate into VECs after directional induction for 7 days, which had good function of tissue repair. The physiological pathway on stem cells by stimulating angiogenesis is expected to become a new target fortissue remodeling.

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.

<b>Objective::To explore the effect of Weichang' an (WCA) on the autophagy of human gastric cancer MKN45 cells and its possible anti-cancer mechanism. <b>Method::MKN45 cells were cultured <italic>in vitro</italic> and incubated with different concentrations (250, 500, 1 000, 2 000 mg·L<sup>-1</sup>) of WCA for 24, 48, 72 h. Cell counting kit-8 (CCK-8) assay was used to detect the cell proliferation. AO/EB Dyeing (AO) staining and monodansylcadaverin (MDC) staining were used to observe the changes of the effect of WCA on autophagosome and autophagic vesicles in gastric cancer MKN45 cells at 48 h. Real-time polymerase chain reaction (Real-time PCR) and Western blot were used to detect microtubule-associated protein 1 light chain 3 (LC3), Beclin1, sequestosome 1 (p62), human autophagy-related gene 5 (ATG5), human autophagy-related gene 7 (ATG7) mRNA and protein expression levels. <b>Result::WCA showed a dose-and-time-dependent growth inhibition at the concentration above 1 000 mg·L<sup>-1</sup>. Compared with the blank group, WCA (500, 1 000, 2 000 mg·L<sup>-1</sup>) significantly inhibited the proliferation of MKN45 cells (<italic>P</italic><0.05, <italic>P</italic><0.01). AO staining and MDC staining showed that autophagosomes and autophagic sacs increased with the rise of WCA concentration compared with the blank group. Real-time PCR and Western blot showed that the expressions of autophagy-related proteins LC3-Ⅱ, Beclin1, ATG5, ATG7, mRNA and protein increased gradually after WCA (1 000 mg·L<sup>-1</sup>) intervention, while p62 expression decreased (<italic>P</italic><0.05, <italic>P</italic><0.01). <b>Conclusion::WCA induces the autophagy of human gastric cancer MKN45 cells in a time-and dose-dependent manner <italic>in vitro</italic>, which may be related to the up-regulation of LC3-Ⅱ, Beclin1, ATG5 and ATG7 as well as the down-regulation of p62 and LC3-Ⅰ.

Objective@#To understand the characteristics of injury deaths of children and adolescents aged 0 to 19 years in Kunming during 2010-2019,and to provide injury prevention and control basis.@*Methods@#Injury mortality data in 2010-2019 were from Kunming population based mortality surveillance system. The characteristics of injury death of children and adolescents were analyzed by descriptive statistical analysis, including mortality rate, composition ratio, the annual percent change,etc.@*Results@#Child and adolescent injury mortality was 23.18/10 5,decreasing by year(t=7.13,P<0.05). Male mortality(31.59/10 5) was higher than female(14.27/10 5)(χ2=376.24,P<0.05),the APC of male was -8.82% and -7.48% in female.The injury mortality of male was higher than that of female at all age group. The injury mortality rate of rural children and adolescents(28.65/10 5) was higher than that of urban children(12.37/10 5)(χ2=297.30,P<0.05),the APC was -8.53% in urban areas and -7.78% in rural areas.The top five causes of injury death of children and adolescents were traffic accident drowning, accidental fall, suicide and accidental mechanical suffocation, accounting for 80.88% of the total injury deaths of children and adolescents.In urban and rural areas,injury death by traffic accident, drowning and rural unintentional falls decreased significantly(t urban=3.17,3.20,t rural=5.66,3.12,4.42,P<0.05). The leading cause of death varied by different age groups.@*Conclusion@#The injury mortality rate of children and adolescents in Kunming city is on the decline. Rural children and adolescents, as vulnerable population to injury death, should receive protective strategies according to their specific characteristics of injuries and deaths in different age groups.
