Colorectal cancer(CRC) is a common malignant tumor worldwide. Due to the treatment intolerance and side effects, CRC rank the top among various cancers regarding the incidence and mortality rates. Therefore, exploring new therapies is of great significance for the treatment of CRC. Aerobic glycolysis(AEG) plays an important role in the microenvironment formation, proliferation, metastasis, and recurrence of CRC and other tumor cells. It has been confirmed that intervening in the AEG pathway can effectively curb CRC. The active ingredients and compound prescriptions of traditional Chinese medicine(TCM) can effectively inhibit the proliferation, metastasis, and drug resistance and regulate the apoptosis of tumor cells by modulating AEG-associated transport proteins [eg, glucose transporters(GLUT)], key enzymes [hexokinase(HK) and phosphofructokinase(PFK)], key genes [hypoxia-inducible factor 1(HIF-1) and oncogene(c-Myc)], and signaling pathways(MET/PI3K/Akt/mTOR). Accordingly, they can treat CRC, reduce the recurrence, and improve the prognosis of CRC. Although AEG plays a key role in the development and progression of CRC, the specific mechanisms are not yet fully understood. Therefore, this article delves into the intrinsic connection of the targets and mechanisms of the AEG pathway with CRC from the perspective of tumor cell glycolysis and explores how active ingredients(oxymatrine, kaempferol, and dioscin) and compound prescriptions(Quxie Capsules, Jiedu Sangen Decoction, and Xianlian Jiedu Prescription) of TCM treat CRC by intervening in the AEG pathway. Additionally, this article explores the shortcomings in the current research, aiming to provide reliable targets and a theoretical basis for treating CRC with TCM.

OBJECTIVE: To investigate the short-term clinical effect of closed reduction single arm external fixator combined with percutaneous needle fixation in the treatment of C1 distal radius fracture in elderly patients. METHODS: Between December 2022 and December 2023, a total of 60 elderly patients diagnosed with type C1 distal radius fractures were treated, comprising 9 males and 51 females. The age ranged from 65 to 84 years old, with an average of (72.69±8.14) years old. Among them, there were 18 cases on the left side and 42 cases on the right side. There were 55 cases of falling injury and 5 cases of traffic accident injury. According to the different surgical methods, the patients were divided into observation group and control group, with 30 cases in each group. The control group underwent manual reduction and unilateral external fixator fixation, consisting of 4 males and 26 females. The mean age was (72.54±8.67) years old. The body mass index (BMI) was (20.61±2.17) kg·m^-2. There were 10 cases on the left side and 20 cases on the right side. Among them, there were 27 cases of falling injury and 3 cases of traffic accident injury. The observation group was treated with manual reduction and unilateral external fixator combined with percutaneous Kirschner wire fixation, including 5 males and 25 females. The mean age was (72.76±7.23) years old. BMI (20.82±2.03) kg·m^-2. The left side was involved in 8 cases and the right side in 22 cases. There were 28 cases of falling injury and 2 cases of traffic accident injury. The changes in radial height, ulnar declination, palmar inclination angle parameters and patient-rated wrist evaluation (PRWE) were assessed on X-ray films before surgery, 2 days after surgery, and 12 weeks after surgery between the two groups. RESULTS: All surgical procedures were successfully completed in both groups without any significant complications. All patients were followed up for a duration from 12 to 20 weeks with an average of(14.50±2.78) weeks. The two groups exhibited significant differences in radial height, palmar inclination angle, and ulnar deviation angle at 2 days and 12 weeks post-operation (P<0.05). However, there was no statistically significant difference observed in radial height, palmar inclination, and ulnar deviation between the two groups at 2 days after the operation (P>0.05). There were significant differences in radial height, palmar inclination angle, and ulnar deviation between the two groups at 12 weeks after operation (P<0.05). At 2 days and 12 weeks after the operation, there were significant differences in PRWE scores of the two groups compared with preoperative scores(P<0.05). At 2 days after the operation, there was no significant difference in PRWE score between the two groups (P>0.05). The PRWE score showed a significant difference between the two groups at 12 weeks post-operation(P<0.05). CONCLUSION The combination of closed reduction and unilateral external fixator, along with percutaneous pin fixation provides move stable fixation for type C1 distal radius fractures. Gradual removal of external fixator further facilitatse the recovery of wrist joint function.

Combined with elastic network model (ENM), the perturbation response scanning (PRS) has emerged as a robust technique for pinpointing allosteric interactions within proteins. Here, we proposed the PRS analysis of drug-target networks (DTNs), which could provide a promising avenue in network medicine. We demonstrated the utility of the method by introducing a deep learning and network perturbation-based framework, for drug repurposing of multiple sclerosis (MS). First, the MS comorbidity network was constructed by performing a random walk with restart algorithm based on shared genes between MS and other diseases as seed nodes. Then, based on topological analysis and functional annotation, the neurotransmission module was identified as the "therapeutic module" of MS. Further, perturbation scores of drugs on the module were calculated by constructing the DTN and introducing the PRS analysis, giving a list of repurposable drugs for MS. Mechanism of action analysis both at pathway and structural levels screened dihydroergocristine as a candidate drug of MS by targeting a serotonin receptor of serotonin 2B receptor (HTR2B). Finally, we established a cuprizone-induced chronic mouse model to evaluate the alteration of HTR2B in mouse brain regions and observed that HTR2B was significantly reduced in the cuprizone-induced mouse cortex. These findings proved that the network perturbation modeling is a promising avenue for drug repurposing of MS. As a useful systematic method, our approach can also be used to discover the new molecular mechanism and provide effective candidate drugs for other complex diseases.

Damarane-type triterpene saponins are the main active ingredients in Gynostemma pentaphyllum (Thunb.) Makino. By using D101 macroporous adsorption resin and silica gel open-columns, C18 medium-pressure column chromatography, and preparative high performance liquid chromatography, we isolated four compounds from the leaves of G. pentaphyllum planted in Guangxi Zhuang Autonomous Region. Their structures were determined by comprehensive analyses of MS, NMR data and circular dichroism spectroscopy and identified as (3β,12β)-dihydroxy-25-peroxyhydrohydrodammarane-20,23-diene-3-O-[β-D-glucopyranosyl(1→2)]-β-D-glucopyranoside (1), (3β,12β,24S)-trihydroxydammarane-20,25-diene-3-O-[β-D-glucopyranosyl(1→2)]-β-D-glucopyranoside (2), (3β,20α)-dihydroxy-24-en-12β,22S-epoxydammarane-3-O-[β-D-glucopyranosyl(1→2)]-β-D-glucopyranoside (3), (3β,12β,20S)-trihydroxydammarane-24-en-3-O-[6-O-acetyl-β-D-glucopyranosyl(1→2)-β-D-glucopyranosyl]-20-O-β-D-xylopyranosyl(1→3)-α-L-rhamnopyranosyl (1→6)-β-D-glucopyranoside (4). Compounds 1-4 are new dammarane-type triterpene saponins.

NLRP3 can recruit proteins such as ASC and pro-caspase1 to form NLRP3 inflammasomes after being stimulated by pathogen and danger signals in vivo,and then induce pyropto-sis and promote the inflammatory reactions to maintain the home-ostasis.However,the overactivation of NLRP3 inflammasomes is closely related to many inflammatory and autoimmune diseases in humans.Targeted inhibition of NLRP3 inflammasomes can sig-nificantly inhibit inflammation and alleviate the relative symp-toms.Therefore,it is an important research direction for treating diseases of NLRP3 inflammasome that searching for effective in-hibitors targeting NLRP3 inflammasome activation and achieving clinical transformation.This review summarizes the latest re-search progress based on the sources of NLRP3 inflammasome inhibitors.

OBJECTIVES: To investigate the risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture and establish a nomogram model for predicting the risk of neonatal asphyxia. METHODS: A retrospective study was conducted with 613 cases of neonatal asphyxia treated in 20 cooperative hospitals in Enshi Tujia and Miao Autonomous Prefecture from January to December 2019 as the asphyxia group, and 988 randomly selected non-asphyxia neonates born and admitted to the neonatology department of these hospitals during the same period as the control group. Univariate and multivariate analyses were used to identify risk factors for neonatal asphyxia. R software (4.2.2) was used to establish a nomogram model. Receiver operator characteristic curve, calibration curve, and decision curve analysis were used to assess the discrimination, calibration, and clinical usefulness of the model for predicting the risk of neonatal asphyxia, respectively. RESULTS: Multivariate logistic regression analysis showed that minority (Tujia), male sex, premature birth, congenital malformations, abnormal fetal position, intrauterine distress, maternal occupation as a farmer, education level below high school, fewer than 9 prenatal check-ups, threatened abortion, abnormal umbilical cord, abnormal amniotic fluid, placenta previa, abruptio placentae, emergency caesarean section, and assisted delivery were independent risk factors for neonatal asphyxia (P<0.05). The area under the curve of the model for predicting the risk of neonatal asphyxia based on these risk factors was 0.748 (95%CI: 0.723-0.772). The calibration curve indicated high accuracy of the model for predicting the risk of neonatal asphyxia. The decision curve analysis showed that the model could provide a higher net benefit for neonates at risk of asphyxia. CONCLUSIONS The risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture are multifactorial, and the nomogram model based on these factors has good value in predicting the risk of neonatal asphyxia, which can help clinicians identify neonates at high risk of asphyxia early, and reduce the incidence of neonatal asphyxia.

OBJECTIVES: To investigate the value of CCKBR^fl/fl villin-Cre mice as a mouse model of salt-sensitive hypertension (SSH). METHODS: In the first part, 2-month-old CCKBR^fl/fl villin-Cre mice (CKO) and control CCKBR^fl/fl mice (WT) were fed with normal diet (0.4% NaCl) or high salt diet (4% NaCl), separately for 6 weeks. In the rescue study, one week of hydrochlorothiazide or saline injection were treated with the CKO mice fed high salt diet. The blood pressure, biochemical indexes, and the expression of small intestinal sodium transporters (NHE3, NKCC1, eNaC) was detected. The organ injury markers (MMP2/MMP9) and the histopathological changes of kidneys were observed, whereas the changes of duodenal sodium absorption were detected by small intestinal perfusion in vivo. RESULTS: The CCKBR^fl/fl villin-Cre mice with high salt intake exhibited high blood pressure, increased duodenal sodium absorption and urinary sodium excretion, and with renal injury. The protein expression of NHE3, NKCC1 and eNaC were also significant increase in the intestine of CKO-HS mice. Treatment with hydrochlorothiazide remarkably attenuated the elevated blood pressure by high salt absorption in the CCKBR^fl/fl villin-Cre mice, but no significant histopathological changes were observed. CONCLUSIONS These results support a crucial role of intestinal Cckbr deficiency on SSH development and the diuretic antihypertension effect in CCKBR^fl/fl villin-Cre mice. The CCKBR^fl/fl villin-Cre mice with the high salt intake may serve as a stable model of salt-sensitive hypertensive induced by sodium overloading.

Objective: To explore the clinical and genetic characteristics of children with dopa-responsive dystonia (DRD) caused by tyrosine hydroxylase (TH) gene variations. Methods: Clinical data of 9 children with DRD caused by TH gene variations diagnosed in the Department of Children Rehabilitation, the Third Affiliated Hospital of Zhengzhou University from January 2017 to August 2022 were retrospectively collected and analyzed, including the general conditions, clinical manifestations, laboratory tests, gene variations and follow-up data. Results: Of the 9 children with DRD caused by TH gene variations, 3 were males and 6 were females. The age at diagnosis was 12.0 (8.0, 15.0) months. The initial symptoms of the 8 severe patients were motor delay or degression. Clinical symptoms of the severe patients included motor delay (8 cases), truncal hypotonia (8 cases), limb muscle hypotonia (7 cases), hypokinesia (6 cases), decreased facial expression (4 cases), tremor (3 cases), limb dystonia (3 cases), diurnal fluctuation (2 cases), ptosis (2 cases), limb muscle hypertonia (1 case) and drooling (1 case). The initial symptom of the very severe patient was motor delay. Clinical symptoms of the very severe patient included motor delay, truncal hypotonia, oculogyric crises, status dystonicus, hypokinesia, decreased facial expression, and decreased sleep. Eleven TH gene variants were found, including 5 missense variants, 3 splice site variants, 2 nonsense variants, and 1 insertion variant, as well as 2 novel variants (c.941C>A (p.T314K), c.316_317insCGT (p.F106delinsSF)). Nine patients were followed up for 40 (29, 43) months, and no one was lost to follow-up. Seven of the 8 severe patients were treated by levodopa and benserazide hydrochloride tablets and 1 severe patient was treated by levodopa tablets. All the severe patients responded well to levodopa and benserazide hydrochloride tablets or levodopa tablets. Although the weight of the patients increased and the drug dosage was not increased, the curative effect remained stable and there was no obvious adverse reaction. One severe patient developed dyskinesia in the early stage of treatment with levodopa and benserazide hydrochloride tablets and it disappeared after oral administration of benzhexol hydrochloride tablets. Until the last follow-up, motor development of 7 severe patients returned to normal and 1 severe patient still had motor delay due to receiving levodopa and benserazide hydrochloride tablets for only 2 months. The very severe patient was extremely sensitive to levodopa and benserazide hydrochloride tablets and no improvement was observed in this patient. Conclusions: Most of the DRD caused by TH gene variations are severe form. The clinical manifestations are varied and easily misdiagnosed. Patients of the severe patients responded well to levodopa and benserazide hydrochloride tablets or levodopa tablets, and it takes a long time before full effects of treatment become established. Long-term effect is stable without increasing the drug dosage, and no obvious side effect is observed.

This study assessed and explored the pharmacological effects and mechanisms of action of IMMH002 {2-amino-2-(2-(4ʹ-(2-ethyloxazol-4-yl)-[1,1ʹ-biphenyl]-4-yl)ethyl)propane-1,3-dio}, a selective sphingosine-1-phosphate receptor subtype 1 (S1P1) modulator, in a concanavalin A (ConA)-induced autoimmune hepatitis (AIH) mouse model. The experimental protocol strictly adhered to the guidelines of the Ethics Committee for Animal Research of the Institute of Materia Medica, Chinese Academy of Medical Sciences and Peking Union Medical College (Approval No.: 00004046). Male ICR mice were pre-treated with the drug for four days, followed by induction of AIH through tail vein injection of ConA protein. Liver function, hepatic tissue pathology, peripheral blood parameters, as well as immunoglobulin G (IgG), inflammatory cytokines, T cell distribution, and inflammatory pathways were evaluated in mice. Results demonstrated that IMMH002 significantly reduced liver function indicators such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST), alleviated hepatic tissue inflammation and necrotic damage, decreased serum IgG levels, and lowered the expression of inflammatory mediators including interleukin 6 (IL-6), tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), and interferon γ (IFN-γ). Additionally, it facilitated T lymphocyte homing, downregulated the phosphorylation of nuclear factor kappa-B (NF-κB), IκB kinase β (IKKβ) and nuclear factor inhibitor protein-α (IκBα) proteins in hepatic tissue and cellular inflammation models. Collectively, IMMH002 effectively ameliorated ConA-induced autoimmune hepatitis in mice, exhibiting extensive anti-inflammatory and anti-necrotic effects, thereby laying a theoretical foundation for AIH clinical treatment.
