Colorectal cancer is a common and malignant tumor in the digestive tract. Invasion and metastasis of cancer cells are key factors leading to the high mortality rate and postoperative recurrence of colorectal cancer. Chemotherapy is the main treatment method for preventing recurrence of this disease. However， there are many toxic side effects in clinical application， which seriously hinder the treatment process. Therefore， it is imperative to search for efficient and low-toxicity drugs. Traditional Chinese medicine （TCM） has a long history of treating colorectal cancer and offers advantages such as safety， effectiveness， multiple targets， multiple pathways and minimal toxic side effects， which have made it increasingly popular worldwide. According to TCM， the pathogenesis of colorectal cancer is rooted in both deficiency and excess. TCM formulas mainly focus on tonifying the body to address the invasion and metastasis of colorectal cancer， such as Jianpi compound， Jianpi Xiaoai decoction， and Bushen Jiedu Sanjie decoction. TCM monomers， such as emodin， berberine， and tanshinone， mainly focus on clearing heat and removing toxin， circulating blood and transforming stasis， and resolving swelling and dispersing nodules. Signaling pathways play a crucial role for analyzing invasion and metastasis， and research has shown that pathways such as Wnt/β-catenin， phosphatidylinositol-3 kinase/protein kinase （PI3K/Akt）， Janus kinase 2/signal transduction and transcription activating factor 3 （JAK2/STAT3）， nuclear factors-κB （NF-κB）， vascular endothelial growth factor （VEGF） play important roles in the invasion and metastasis of colorectal cancer. The invasion and metastasis of colorectal cancer can be inhibited via regulating the key proteins and related factors in these pathways. In this review， we searched various literature databases， such as PubMed， China National Knowledge Infrastructure （CNKI）， and VIP， using keywords such as "colorectal cancer"， "signaling pathway"， "invasion and metastasis"， and "traditional Chinese medicine"， to summarize and analyze the relevant pathways of TCM compounds and monomers against invasion and metastasis of colorectal cancer published in the past five years. The review aims to provide new insights and references for in-depth research on the therapy for invasion and metastasis of colorectal cancer and new drug development.

Abstract: To investigate the in vitro release, in vivo pharmacokinetics, and the in vitro-in vivo correlation of progesterone suspension injection, self-made progesterone suspension injection was taken as an example. The in vitro release curves of three different particle sizes of progesterone suspension injections were measured using paddle method and dialysis bag method. The in vivo pharmacokinetic characteristics of self-made progesterone suspension injection was studied on SD rats. The plasma concentration of self-made progesterone preparation was detected after intramuscular injection, and correlated with the in vitro release profiles obtained by the dialysis bag method after processing by Wagner-Nelson method. The results showed that when the in vitro release of three different particle sizes of progesterone suspension injections was measured by the paddle method, more than 85% was rapidly released within 20 min, while 85% cumulative release was reached at 40 h, 84 h and 120 h by dialysis bag method, respectively. The release rate obtained by the dialysis bag method was basically consistent with the in vivo release trend, with a correlation coefficient of >0.95, indicating a strong in vivo and in vitro correlation. This study provides some reference for the establishment of the in vitro and in vivo correlation of long-acting suspension injection.

ObjectiveTo validate the efficacy of Yunpi Huatan Tongqiao prescription （YHTP） in down-regulating glycolysis to modulate microglia phenotype and improve inflammation and cognitive memory deficits in obstructive sleep apnea （OSA） mice. MethodForty-eight male Balb/C mice were randomly divided into a normal group， a model group， a montelukast sodium group （30 mg·kg^-1）， and low， medium， and high dose groups of YHTP （8.28， 16.56， and 33.12 g·kg^-1）， with 8 mice in each group. All groups， except the normal group， received intraperitoneal injections of lipopolysaccharide （LPS） and underwent chronic intermittent hypoxia （CIH） modeling for 4 weeks. Subsequently， the mice were treated with medications for 4 weeks and then sampled. Animal behavioral tests assessed memory impairment due to hypoxia. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to measure mRNA expression levels of M1-associated inflammatory factors interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， and markers such as T lymphocyte activation antigen （CD86） and inducible nitric oxide synthase （iNOS）， as well as M2-associated inflammatory factors interleukin-10 （IL-10）， transforming growth factor-β （TGF-β）， and the marker mannose receptor （CD206） in hippocampal tissue. Western blot was employed to detect differences in the expression of M1 and M2 microglia phenotypic markers （CD86， CD206） and glycolysis-related proteins glucose transporter type 1 （GLUT1）， hexokinase 2 （HK2）， phosphofructokinase （PFKM）， pyruvate kinase 2 （PKM2）， and monocarboxylic acid transporter 1 （MCT1）. ResultBehavioral tests showed that compared to the results in the normal group， the Y-maze autonomous alternation rate was significantly reduced in the model group （P<0.01）. The latency time for the target hole in the Barnes' maze during the training period （days 2， 3， 4） and testing period （days 5， 12） was significantly increased （P<0.05， P<0.01）. M1 glial cell markers CD86 and iNOS， as well as inflammatory factors IL-1β and TNF-α mRNA， were significantly elevated （P<0.01）. In contrast， the mRNA expression of M2 glial cell markers IL-10， CD206， and TGF-β was significantly reduced （P<0.01）. The protein expression of glycolytic proteins HK2， PFKM， PKM2， MCT1， and the M1 marker CD86 was significantly increased （P<0.05， P<0.01）， while M2 marker CD206 protein expression was significantly decreased （P<0.01）. Compared to the results in the model group， the Y-maze autonomous alternation rate was significantly increased in the medium and high dose groups of YHTP （P<0.05， P<0.01）. The latency time for the target hole during the training （day 4） and testing periods （days 5， 12） was significantly reduced （P<0.01）. Real-time PCR results indicated that mRNA expression levels of M1-related pro-inflammatory factors in the hippocampal tissue were significantly reduced in the low， medium， and high dose groups of YHTP （P<0.01）， while M2-related inflammatory factors' mRNA expression was significantly increased （P<0.01）. Western blot results showed that in the medium and high dose groups of YHTP， the expression of the M1 marker CD86 in the hippocampus was reduced， whereas the expression of the M2 marker CD206 was significantly increased （P<0.01）， with a significant decrease in the expression of glycolysis-related proteins （P<0.01）. ConclusionYHTP can improve inflammation and cognitive impairment induced by hypoxia in OSA model mice. This is achieved by downregulating glycolysis in brain microglia， inhibiting M1 activation， reducing pro-inflammatory factor release， and promoting M2 activation， thereby exerting a therapeutic effect on inflammation and cognitive impairment caused by OSA.

Objective To explore the relationship between preoperative coronary angiography and postoperative acute kidney injury (AKI) in cardiac surgery. Methods The clinical data of patients who underwent coronary angiography within 30 days before cardiac surgery in the First Affiliated Hospital of Xi’an Jiaotong University from January 2015 to April 2019 were retrospectively analyzed. Univariate analysis and multivariate logistic regression analyses were used to explore the relationship between the interval from preoperative coronary angiography to cardiac surgery and postoperative AKI. Results Finally 1 112 patients were collected, including 700 males and 412 females, with a median age of 61 (55, 66) years. The incidence of postoperative AKI was 40.8% (454/1 112), of which grade 2-3 AKI accounted for 11.9%. Multivariate analysis showed that age (OR=1.049, 95%CI 1.022-1.077, P<0.001), body mass index (OR=1.065, 95%CI 1.010-1.123, P=0.020) and time interval between preoperative coronary angiography and cardiac surgery within 24 hours (OR=1.625, 95%CI 1.116-2.364, P=0.011) were independent predictors of postoperative AKI. Patients who underwent coronary angiography within 24 hours before surgery had a 10.6% higher incidence of postoperative AKI compared to those who underwent angiography ≥24 hours before surgery (P=0.004). Patients who underwent valve surgery with or without coronary artery bypass grafting (CABG) had a higher risk of AKI than those who only underwent CABG. The in-hospital stay of patients who developed AKI was 2 days longer than those without AKI. However, undergoing coronary angiography within 24 hours before cardiac surgery did not prolong the length of ICU stay or hospital stay, nor did it increase the risk of death or renal failure after the operation. Conclusion Undergoing coronary angiography within 24 hours before cardiac surgery increases the risk of postoperative AKI.

Background Previous research on chlorinated paraffins (CPs) in fine particulate matter (PM_2.5) has predominantly focused on short- and medium-chain chlorinated paraffins (SCCPs and MCCPs), and few studies could simultaneously determine short-, medium-, and long-chain chlorinated paraffins (LCCPs). Simultaneous extraction and determination of SCCPs, MCCPs, and LCCPs in PM_2.5 could provide technical support for their environmental monitoring and human health risk assessment. Objective To establish a method based on QUEChERS pretreatment method in conjunction with ultra-performance liquid chromatography-quadrupole/orbitrap high resolution mass spectrometry for simultaneously determining the levels of SCCPs, MCCPs, and LCCPs in PM_2.5. Methods The extraction solvents, extraction salts, and extraction steps of a QuEChERS method were optimized. The extraction efficiencies of the target substances were compared under 4 extraction solvents [acetonitrile, dichloromethane, and n-hexane solvents in sequence; acetonitrile: dichloromethane: n-hexane = 1: 1: 2 (v/v/v) mixed solvent; 1% acetic acid-acetonitrile: dichloromethane: n-hexane = 1: 1: 1 (v/v/v) mixed solvent; acetonitrile: dichloromethane: n-hexane = 1: 1: 1 (v/v/v) mixed solvent], 2 dehydrated salts (anhydrous MgSO₄+NaCl and anhydrous Na₂SO₄+NaCl), 2 purification salts (C18 and PSA), and 4 vortex time (5, 7.5, 10, and 12.5 min) conditions. Then internal standard was utilized to estimate linear range and detection limit of the refined QuEChERS approach. Results The linearities of SCCPs, MCCPs, and LCCPs were good in the range of 10~1000 ng·mL⁻¹ with the correlation coefficients all greater than 0.96. The method detection limits (MDLs) ranged from 0.01 to 0.29 ng·m⁻³. The spiked recoveries of SCCPs, MCCPs, and LCCPs at the low, medium, and high concentrations were 77.38%-81.64%, 93.11%-99.78%, and 87.41%-101.39%, respectively, and the relative standard deviations (RSDs) were 2.90%-12.84%. This method was used to determine the CPs levels in 11 PM_2.5 samples from Shijiazhuang. The positive rates of ∑SCCPs, ∑MCCPs, and ∑LCCPs were all 100%, the concentration ranges were 0.24-2.18 ng·m⁻³ (mean 0.84 ng·m⁻³), 0.17-1.67 ng·m⁻³ (mean 0.70 ng·m⁻³), and 0.01-0.16 ng·m⁻³ (mean 0.04 ng·m⁻³), respectively, and the percentages to ΣCPs were 52.95%, 44.39%, and 2.66%, respectively. Conclusion The method established in this study is simple, time-saving, solvent saving, and can simultaneously detect SCCPs, MCCPs, and LCCPs in PM_2.5, which is suitable for the determination of PM_2.5 samples in large quantities, and can also provide a reference for the detection methods of other halogenated organic compounds in PM_2.5.

Objective:To explore Lijin Zhenggu Therapy combined with heat supplementing needles on cartilage damage, immune balance, and liver X receptor NF-κB in knee osteoarthritis of New Zealand white rabbits.Methods:Totally　60 New Zealand white rabbits were divided into normal group, model group, Lijin Zhenggu Therapy group, heat supplementing needles group, and a combination group using random number table method, with 12 rabbits in each group. Except for the normal group, all other groups were established with knee osteoarthritis models. The Lijin Zhenggu Therapy group was treated with Lijin Zhenggu Therapy, the heat supplementing needles group was treated with heat supplementing needles, the combination group was treated with Lijin Zhenggu Therapy combined with heat supplementing needles. The pain threshold of each group of white rabbits was observed using a pain meter; HE staining was used to observe the morphology of cartilage damage in each group of white rabbits; ELISA was used to detect PGE 2, IL-1β and β-EP in the articular cartilage tissue of white rabbits in each group; PCR was used to detect the levels of LXRα and NF-κB mRNA. Western blot was used to detect toll like receptor 4 (TLR4), myeloid differentiation factor (MyD88), interferon regulatory factor-7 (IRF-7) in synovial tissue of rabbits in each group. Results:Compared with model group, the pain threshold of rabbits in heat supplementing needles group, Lijin Zhenggu Therapy group and combination group increased ( P<0.05); the levels of PGE 2 and IL-1β decreased ( P<0.05), while the level of β-EP increased ( P<0.05). LXRα mRNA level increased ( P<0.05), and NF-κB mRNA level decreased ( P<0.05); the expressions of TLR4, MyD88, IRF-7 and NF-κB P65 in synovial tissue decreased ( P<0.05). Conclusions:Lijin Zhenggu Therapy combined with heat supplementing needles can reduce the levels of PGE 2 and IL-1β, increase β-EP level, improve pain and cartilage tissue morphology. The mechanism may be related to the regulation of liver X receptor nuclear factor NF-κB pathway, reduction of inflammatory reactions and immunity maintaining.

Background::The association and its population heterogeneities between low-density lipoprotein cholesterol (LDL-C) and all-cause and cardiovascular mortality remain unknown. We aimed to examine the dose-dependent associations of LDL-C levels with specific types of cardiovascular disease (CVD) mortality and heterogeneities in the associations among different population subgroups.Methods::A total of 2,968,462 participants aged 35-75 years from China Health Evaluation And risk Reduction through nationwide Teamwork (ChinaHEART) (2014-2019) were included. Cox proportional hazard models and Fine-Gray subdistribution hazard models were used to estimate associations between LDL-C categories (<70.0, 70.0-99.9, 100.0-129.9 [reference group], 130.0-159.9, 160.0-189.9, and ≥190.0 mg/dL) and all-cause and cause-specific mortality.Results::During a median follow-up of 3.7 years, 57,391 and 23,241 deaths from all-cause and overall CVD were documented. We observed J-shaped associations between LDL-C and death from all-cause, overall CVD, coronary heart disease (CHD), and ischemic stroke, and an L-shaped association between LDL-C and hemorrhagic stroke (HS) mortality ( P for non-linearity <0.001). Compared with the reference group (100.0-129.9 mg/dL), very low LDL-C levels (<70.0 mg/dL) were significantly associated with increased risk of overall CVD (hazard ratio [HR]: 1.10, 95% confidence interval [CI]: 1.06-1.14) and HS mortality (HR: 1.37, 95% CI: 1.29-1.45). Very high LDL-C levels (≥190.0 mg/dL) were associated with increased risk of overall CVD (HR: 1.51, 95% CI: 1.40-1.62) and CHD mortality (HR: 2.08, 95% CI: 1.92-2.24). The stronger associations of very low LDL-C with risk of CVD mortality were observed in individuals with older age, low or normal body mass index, low or moderate 10-year atherosclerotic CVD risk, and those without diagnosed CVD or taking statins. Stronger associations between very high LDL-C levels and all-cause and CVD mortality were observed in younger people. Conclusions::People with very low LDL-C had a higher risk of all-cause, CVD, and HS mortality; those with very high LDL-C had a higher risk of all-cause, CVD, and CHD mortality. On the basis of our findings, comprehensive health assessment is needed to evaluate cardiovascular risk and implement appropriate lipid-lowering therapy for people with very low LDL-C.

Objective:To investigate the characteristics of executive function of preschool children with high functioning autism spectrum disorder (HFA) and with global developmental delay (GDD), and the differences among HFA, GDD and typically developmental (TD) children.Methods:From January 2020 to January 2021, 20 male HFA, 20 male GDD and 20 male TD children aged 4-6 years who visited the Psychological Behavior Clinic of the Child Health Department of Guiyang Maternal and Child Health Hospital and the Developmental Behavior Clinic of the Children Health Department of the Ninth People's Hospital in Chongqing were selected for comparative study.The executive function of HFA, GDD and TD children was assessed with the behavior rating scale of executive function-preschool version(BRIEF-P) and the executive function task program (EF-TOUCH). SPSS 26.0 software was used for statistical analysis, including variance test, independent sample t-test, χ2 test, Kruskal Wallis test and Mann-Whitney U test. Results:In the EF-TOUCH program task, the accuracy of the three groups of children's performance in the pig task (Pig), the silly sounds game (SSG), the working memory task (pick the picture, PTP) and the task of cognitive flexibility (something's the same, STS) were statistically different(Pig: HFA group: 0.87(0.76, 0.99), GDD group: 0.97(0.85, 0.99), TD group: 1.00(0.98, 1.00), χ2=15.646, P<0.001; SSG: HFA group: 0.76(0.53, 0.91), GDD group: 0.76(0.65, 0.99), TD group: 0.94(0.76, 1.00), χ2=6.448, P=0.040; PTP: HFA group: 0.66±0.18, GDD group: 0.66±0.19, TD group: 0.78±0.11; F=3.221, P=0.048; STS: HFA group: 0.67(0.63, 0.70), GDD group: 0.72(0.46, 0.78), TD group: 0.87(0.83, 0.90), χ2=26.898, P<0.001). The accuracies of Pig, SSG, PTP and STS in HFA group were significantly lower than those in TD group(all P<0.05), and the accuracies of Pig and STS in GDD group were significantly lower than those in TD group(both P<0.05). In inhibition control, there were statistically differences in response time of Pig and SSG among the three groups (Pig: HFA group: (1 694.36±222.83)ms, GDD group: (1 513.46±244.91)ms, TD group: (1 444.84±197.95)ms, F=5.810, P=0.005; SSG: HFA group: (2 202.42±195.58)ms, GDD group: (2 116.52±323.27)ms, TD group: (1 937.17±252.74)ms, Z=4.610, P=0.014). There were no significant differences in the reaction time of Arrows task ( P>0.05). There were significant differences in BRIEF-P inhibition control, organizational planning, inhibition self-regulation, cognitive flexibility and total scores among the three groups ( P<0.05), while there were no significant differences in the scores of other factors and dimensions ( P>0.05). Conclusion:The executive function of pre-school children with high functioning autism spectrum disorder and children with global developmental delay is impaired.The executive function of children with high functioning autism spectrum disorder and children with global developmental delay is significantly different from that of typically developmental children of the same age.Moreover, the executive function of children with HFA is more severely damaged from all components than that of children with GDD.

OBJECTIVES: Congenital birth defects are the main source of disease burden among children under 5 years old in China. This study aims to compare the trends in disease burden of different congenital birth defects among Chinese children under 5 years old from 1990 to 2019, and to provide a scientific basis for strengthening the comprehensive prevention and control of birth defects. METHODS: Based on data from the Global Burden Disease (GBD) in 2019, the incidence mortality rate, and disability-adjusted life years (DALYs) rate of congenital birth defects among Chinese children under 5 years old from 1990 to 2019 were selected as evaluation indicators. The Joinpoint regression model was used to analyze the trends in disease burden of different types with congenital birth defects over three decades. The study also compared the differences in disease burden of congenital birth defects among children under 5 years old by gender. RESULTS: Compared to 1990, the DALYs rates of congenital heart anomalies (1 931.91/100 000), digestive congenital anomalies (364.63/100 000), neural tube defects (277.20/100 000), congenital musculoskeletal and limb anomalies (133.33/100 000), and Down syndrome (128.22/100 000) in children under 5 years old in China in 2019 were decreased 70.78%, 71.61%, 86.21%, 36.84% and 73.65%, respectively. From 1990 to 2019, the mortality rates and DALYs rates of different congenital birth defects showed an overall downward trend, but the incidence of digestive congenital anomalies and Down syndrome showed an upward trend after 2005 and 2001, respectively. Except for congenital musculoskeletal and limb anomalies, incidence of the remaining categories of birth defects were higher in boys than that in girls. CONCLUSIONS The disease burden of congenital birth defects in children under 5 years old in China is decreased substantially from 1990 to 2019, but the burden of congenital heart anomalies is still serious and the incidence of some birth defect diseases is on the rise, and it is still crucial to strengthen the prevention and treatment for birth defects in children and propose targeted measures according to their gender characteristics.
