Aim To explore the mechanism by which the compound Chaijin Jieyu formula(CCJJY)regulates the TLR4/NLRP3 signaling pathway to inhibit central oxidative stress and improve hippocampal synaptic plasticity damage in depression.Methods SD rats were randomly divided into the control group,chronic unpredictable mild stress group,sleep deprivation group,chronic unpredictable mild stress combined with sleep deprivation group,positive drug group(venlafax-ine+melatonin),low-dose group of CCJJY,medium dose group of CCJJY,and high-dose group of CCJJY,with nine rats in each group.Except for the control group,a rat model of depression complicated with in-somnia was established using chronic unpredictable mild stress combined with sleep deprivation.Depres-sion-like and sleep behaviors in rats were evaluated through weight,food intake,water maze,and pento-barbital sodium tests.ELisa was used to detect ROS,AANAT,and HPLC-EC was used to detect 5-HT con-tent,while Western blot/RT-PCR was used to detect the expression of IL-1β,TLR4,NLRP3,PSD-95,and SYN related proteins and mRNA.HE and Golgic stai-ning were used to observe the pathological changes in the third ventricle,hippocampus,and neuronal synap-ses.Results Compared with the control group,the depression-like behaviors of the model group rats were significant.The expression of IL-1β,TLR4,and NL-RP3 in the hippocampus increased,while the expres-sion of PSD-95 and SYN decreased.Activation of NL-RP3 inflammasomes led to "sleeve like" pathological changes in the third ventricle,with hippocampal neu-rons undergoing apoptosis and significant damage to neuronal synaptic plasticity.Compared with the model group,after intervention with CCJJY,the expression of ROS,IL-1β,TLR4,and NLRP3 decreased,while the expression of AANAT,5-HT,PSD-95,and SYN in-creased.Pathological damage to the third ventricle and hippocampal neurons was repaired.Conclusion The CCJJY improves hippocampal synaptic plasticity dam-age in depression by regulating the TLR4/NLRP3 sig-naling pathway to inhibit central oxidative stress.

Objective:We aimed to develop a novel visualized model based on nomogram to predict postoperative overall survival.Methods:This was a multicenter, retrospective, observational cohort study, including participants with histologically confirmed gastric and colorectal cancer who underwent radical surgery from 11 medical centers in China from August 1, 2015 to June 30, 2018. Baseline characteristics, histopathological data and nutritional status, as assessed using Nutrition Risk Screening 2002 (NRS 2002) score and the scored Patient-Generated Subjective Global Assessment, were collected. The least absolute shrinkage and selection operator regression and Cox regression were used to identify variables to be included in the predictive model. Internal and external validations were performed.Results:There were 681 and 127 patients in the training and validation cohorts, respectively. A total of 188 deaths were observed over a median follow-up period of 59 (range: 58 to 60) months. Two independent predictors of NRS 2002 and Tumor-Node-Metastasis (TNM) stage were identified and incorporated into the prediction nomogram model together with the factor of age. The model's concordance index for 1-, 3- and 5-year overall survival was 0.696, 0.724, and 0.738 in the training cohort and 0.801, 0.812, and 0.793 in the validation cohort, respectively.Conclusions:In this study, a new nomogram prediction model based on NRS 2002 score was developed and validated for predicting the overall postoperative survival of patients with gastric colorectal cancer. This model has good differentiation, calibration and clinical practicability in predicting the long-term survival rate of patients with gastrointestinal cancer after radical surgery.

The modernization and development of traditional Chinese medicine has led to higher standards for the quality of traditional Chinese medicine products. The extraction process is a crucial component of traditional Chinese medicine production, and it directly impacts the final quality of the product. However, the currently relied upon methods for quality assurance of the extraction process, such as simple wet chemical analysis, have several limitations, including time consumption and labor intensity, and do not offer precise control of the extraction process. As a result, there is significant value in incorporating near-infrared spectroscopy (NIRS) in the production process of traditional Chinese medicine to improve the quality control of the final products. In this study, we focused on the extraction process of Xiao'er Xiaoji Zhike oral liquid (XXZOL), using near-infrared spectra collected by both a Fourier transform near-infrared spectrometer and a portable near-infrared spectrometer. We used the concentration of synephrine, a quality control index component specified by the pharmacopoeia, to achieve rapid and accurate detection in the extraction process. Moreover, we developed a model transfer method to facilitate the transfer of models between the two types of near-infrared spectrometers (analytical grade and portable), thus resolving the low resolution, poor performance, and insufficient prediction accuracy issues of portable instruments. Our findings enable the rapid screening and quality analysis of XXZOL onsite, which is significant for quality monitoring during the traditional Chinese medicine production process.

OBJECTIVE:
To investigate the efficacy, prognosis and safety of decitabine combined with modified EIAG regimen in the treatment of patients with relapsed/refractory acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (MDS).
METHODS:
The clinical data of 44 patients with relapsed/refractory AML and high-risk MDS admitted to our hospital from January 2017 to December 2020 were analyzed retrospectively. The patients were equally divided into D-EIAG group (decitabine combined with EIAG regimen) and D-CAG group (decitabine combined with CAG regimen) according to clinical treatment regimen. The complete response (CR), CR with incomplete hematologic recover (CRi), morphologic leukemia-free state (MLFS), partial response (PR), overall response rate (ORR), modified composite complete response (mCRc), overall survival (OS) time, 1-year OS rate, myelosuppression and adverse reactions between the two groups were compared.
RESULTS:
In D-EIAG group, 16 patients (72.7%) achieved mCRc (CR+CRi+MLFS), 3 patients (13.6%) achieved PR, and ORR (mCRc+PR) was 86.4%. In D-CAG group, 9 patients (40.9%) achieved mCRc, 6 patients (27.3%) achieved PR, and ORR was 68.2%. Difference was observed in mCRc rate between the two groups (P=0.035), but not in ORR (P>0.05). The median OS time of D-EIAG group and D-CAG group was 20 (2-38) months and 16 (3-32) months, and 1-year OS rate was 72.7% and 59.1%, respectively. There was no significant difference in 1-year OS rate between the two groups (P>0.05). After induction chemotherapy, the median time for absolute neutrophil count recovery to 0.5×109/L in D-EIAG group and D-CAG group was 14 (10-27) d and 12 (10-26) d, for platelet count recovery to 20×109/L was 15 (11-28) d and 14 (11-24)d, the median red blood cell suspension transfusion volume was 8 (6-12) U and 6 (6-12) U, and the median apheresis platelet transfusion volume was 4 (2-8) U and 3 (2-6) U, respectively. There were no statistically significant differences in comparison of the above indicators between the two groups (P>0.05). The hematological adverse reactions of patients were mainly myelosuppression. Grade III-IV hematological adverse events occurred in both groups (100%), with no increase in the incidence of non-hematological toxicities such as gastrointestinal reactions or liver function damage.
CONCLUSION
Decitabine combined with EIAG regimen in the treatment of relapsed/refractory AML and high-risk MDS can improve remission rate, provide an opportunity for subsequent therapies, and have no increase in adverse reactions compared with D-CAG regimen.

ObjectiveTo investigate the effects of gene polymorphism on the pharmacokinetics of sufentanil (SUF) in children with congenital heart disease undergoing interventional cardiac surgery. MethodsA total of 168 ASA grade Ⅱ patients aged 6~72 months and scheduled for interventional cardiac surgery were enrolled into the study. Anesthesia was induced by using propofol 2 mg·kg-1, SUF 0.3 μg·kg-1 and cisatracurium besilate 0.2 mg·kg-1. Propofol 8 mg·kg-1·h-1 was administered to maintain anesthesia. Blood samples were collected at 5, 10, 20, 30, 45, 60, 75, 90 min after administration of SUF by dilution sampling method. Plasma concentration of sufentanil was determined by UHPLC-MS/MS method and pharmacokinetic parameters were calculated by Phoenix WinnonlintmTM software. The genotypes were detected by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). The genotypes and pharmacokinetic data were analyzed by SNPStats software and the model with the smallest value of Akaike information criterion was chosen as the best model. ResultsThirty single nucleotide polymorphisms (SNPs) in 9 genes possibly involved in pharmacokinetics, pharmacodynamics related targets, metabolic enzymes, transporters and pathways of SUF were examined. ABCG2 rs2054576 and OPRM1 rs4870266 were found to be related to area under the curve (AUC) (P<0.05). OPRM1 rs2236257 was correlated with the apparent volume of distribution (Vd) (P<0.05). CYP3A4 rs2246709, OPRM1 rs2236257 and rs4870266 were associated with the drug clearance rate (CL) (P<0.05). ConclusionGene polymorphisms of ABCG2 rs2054576,CYP3A4 rs2246709 and OPRM1 rs2236257, rs4870266 could significantly affect the pharmacokinetics of SUF in children undergoing interventional cardiac surgery.

ObjectiveTo explore the mechanism of Wutou Chishizhi Wan in regulating autophagy and phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/glycogen synthase kinase-3β (GSK-3β) signaling pathway in rats with myocardial ischemia-reperfusion injury (MIRI). MethodSixty male SD rats were randomly assigned into the normal group (normal saline), model group (normal saline), positive control (trimetazidine, 5.4 mg·kg-1) group, and low-, medium-, and high-dose (1.63, 4.9, 14.7 g·kg-1, respectively) Wutou Chishizhi Wan groups, with 10 rats in each group. The rats in other groups except the normal group underwent left anterior descending coronary artery ligation for modeling. Electrocardiogram was employed to detect the ST-segment elevation to evaluate the modeling. Hematoxylin-eosin (HE) staining was performed to reveal the damage of myocardial tissue. The levels of aspartate aminotransferase (AST) and creatine kinase (CK) were determined by colorimetry, and those of cardiac troponin T (cTnT) and myoglobin (MYO) by enzyme-linked immunosorbent assay (ELISA). Western blot was carried out to determine the protein levels of microtubule-associated proteins 1 light chain 3 (LC3), autophagy-related gene Beclin-1, PI3K, Akt, GSK-3β, p-GSK-3β, and p-Akt. ResultCompared with the normal group, the modeling elevated the serum levels of AST, CK, cTnT, and MYO (P<0.01), destroyed the arrangement of myocardial cells abd nucle, twisted and broken myocardial fibers, up-regulated the protein levels of LC3Ⅱ/Ⅰ and Beclin-1 (P<0.01), and down-regulated the protein levels of PI3K, p-Akt, and p-GSK-3β (P<0.01). Compared with the model group, trimetazidine and Wutou Chishizhi Wan (all the doses) lowered the levels of AST, CK, cTnT, and MYO in serum (P<0.01), restored the arrangement of myocardial cells and muscle fibers, reduced necrosis, down-regulated the protein level of Beclin-1 (P<0.01), and up-regulated the protein levels of PI3K, p-Akt, and p-GSK-3β (P<0.01). Additionally, Wutou Chishizhi Wan (all the doses) down-regulated the protein level of LC3Ⅱ/Ⅰ (P<0.05, P<0.01). Compared with those in the trimetazidine group, the serum AST level rose in the low-dose Wutou Chishizhi Wan group (P<0.05) and declined in the high-dose group (P<0.01), and the protein level of Beclin-1 was down-regulated in the medium-dose group (P<0.01). Additionally, the trimetazidine group had higher protein level of LC3Ⅱ/Ⅰ than medium- and high-dose Wutou Chishizhi Wan groups (P<0.05, P<0.01), higher protein level of PI3K than low-, medium-, and high-dose groups (P<0.01), lower protein level of p-Akt than low- and medium-dose groups (P<0.01), and higher p-GSK-3β protein level than the medium-dose group (P<0.01). ConclusionDifferent doses of Wutou Chishizhi Wan can ameliorate MIRI, and the high dose has the best effect. Wutou Chishizhi Wan can reduce the activity of myocardial injury markers AST, CK, cTnT, and MYO, and alleviate the pathological damage of myocardial tissue. It can down-regulate the protein levels of beclin-1, LC3Ⅱ/Ⅰ, and up-regulate those of PI3K, p-Akt, and p-GSK-3β. In summary, Wutou Chishizhi Wan may inhibit excessive autophagy and regulate the PI3K/Akt/GSK-3β signaling pathway to exert protective effect on MIRI rats.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ2=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.
