ObjectiveTo observe the effects of Jiangtang No. 3 prescription on inflammatory pathways and insulin resistance-related indicators in rats with type 2 diabetes mellitus （T2DM）， and to elucidate its molecular mechanism in combating diabetes. MethodsA T2DM rat model was established using a high-fat diet combined with intraperitoneal injection of streptozotocin （STZ）. Successfully modeled rats were randomly assigned to the model group， metformin group， and low-， medium-， and high-dose Jiangtang No. 3 prescription groups， and a normal group was also set. Daily gavage was administered for 8 weeks as follows： metformin at 0.1 g·kg^-1·d^-1， Jiangtang No. 3 prescription granules at 1.62， 3.24， 6.48 g·kg^-1·d^-1 for the respective dose groups， and sterile water for the normal and model groups. Rat body weight， fasting blood glucose （FBG）， oral glucose tolerance test （OGTT）， and insulin tolerance test （ITT） were measured. After drug intervention， enzyme-linked immunosorbent assay （ELISA） was used to determine serum levels of total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein cholesterol （LDL）， high-density lipoprotein cholesterol （HDL）， non-esterified fatty acids （NEFA）， interleukin （IL）-1β， IL-18， and insulin （INS）. Hematoxylin-eosin （HE） staining was used to observe morphological changes in adipose tissue. Real-time quantitative PCR was used to detect the mRNA expression of Toll-like receptor 4 （TLR4）， nuclear factor-κB （NF-κB）， NOD-like receptor protein 3 （NLRP3）， Caspase-1， IL-1β， IL-18， and gasdermin D （GSDMD） in adipose tissue. Western blot was used to measure the corresponding protein expression levels. ResultsCompared with the model group， Jiangtang No. 3 prescription groups exhibited significantly increased body weight （P<0.05， P<0.01）， significantly reduced FBG （P<0.05， P<0.01）， significant reductions in TC， TG， NEFA， and LDL （P<0.05， P<0.01）， and a significant increase in HDL （P<0.01）. Serum levels of inflammatory mediators IL-1β and IL-18 were significantly decreased （P<0.01）， the homeostatic model assessment of insulin resistance （HOMA-IR） index was significantly reduced （P<0.05， P<0.01）， and adipose tissue pathology was improved. The protein expression levels of TLR4， NF-κB， NLRP3， Caspase-1， IL-1β， IL-18， and GSDMD were markedly decreased （P<0.05， P<0.01）， and the mRNA expression levels of these indicators were also significantly downregulated （P<0.05， P<0.01）. Some effects were superior to those of the positive control drug metformin， and certain indicators exhibited dose-dependent improvements. ConclusionT2DM rats display significant inflammatory responses， disordered glucose and lipid metabolism， and insulin resistance. Jiangtang No. 3 prescription effectively suppresses inflammatory mediators， improves glucose and lipid metabolism and insulin resistance， and ameliorates pathological changes in adipose tissue. Its mechanism may be related to the regulation of the TLR4/NF-κB/NLRP3 signaling pathway in visceral adipose tissue， thereby influencing downstream inflammatory mediators.

OBJECTIVE To explore the antidepressant mechanism of Wenyang jieyu granules （WYJYG） via the NOD-like receptor thermal protein domain associated protein 3 （NLRP3）/apoptosis-associated speck-like protein containing a CARD （ASC）/Caspase-1 pathway. METHODS A rat model of depression was established by chronic unpredictable mild stress combined with single-housing for 42 consecutive days.The experiment set up blank group， model group， MCC950 （NLRP3 inflammasome inhibitor） group （10 mg/kg）， fluoxetine group （positive control，2.08 mg/kg），low-dose WYJYG（3.78 g/kg） and high-dose WYJYG group （7.56 g/kg），with 10 rats in each group. From the 22nd day of the experiment， rats in the fluoxetine group， low-dose and high-dose WYJYG groups were intragastrically administered with the corresponding drugs and intraperitoneally injected with an equal volume of normal saline. Rats in the MCC950 group were intraperitoneally injected with MCC950 at the corresponding concentration and intragastrically administered with an equal volume of distilled water. Rats in the blank group and model group were given an equal volume of distilled water by gavage and an equal volume of normal saline by intraperitoneal injection. All interventions were performed once a day for 21 consecutive days. Behavioral tests were conducted once a week. After the last administration， the contents of ASC， ionized calcium binding adaptor molecule 1 （Iba1）， interleukin-1β （IL-1β）， and IL-18 in hippocampal tissues were detected. The protein expressions of NLRP3， cluster of differentiation 68 （CD68）， Caspase-1， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein were determined， and neuronal apoptosis was observed. RESULTS After the last administration， compared with the model group， the open-field activity time was significantly prolonged （ P ＜0.05）， and the latency to feed in a novel environment was significantly shortened （ P ＜0.05） in rats of the high-dose WYJYG group. In hippocampal tissue， the contents of ASC， Iba1， IL-1β， and IL-18， as well as the protein expression levels of NLRP3， Caspase-1， and CD68， and the positive rate of neuronal apoptosis were all significantly decreased/downregulated （ P ＜0.05）. Bcl-2 protein expression was significantly upregulated （ P ＜0.05）， and the density of neuronal apoptosis-positive cells was significantly reduced （ P ＜0.05）. CONCLUSIONS WYJYG play on antidepressant role by inhibiting the NLRP3/ASC/Caspase-1 pathway， reducing microglia-mediated neuroinflammation， and inhibiting hippocampal neurons apoptosis.

As people’s attention to health continues to increase, the market demand for traditional Chinese medicine (TCM) is growing steadily. The quality and safety of Chinese medicinal materials have attracted unprecedented social attention. In particular, the issue of exogenous harmful residue pollution in TCM has become a hot topic of concern for both regulatory authorities and society. The Chinese Pharmacopoeia 2025 Edition further refines the detection methods and limit standards for exogenous harmful residues in TCM. This not only reflects China’s high-level emphasis on the quality and safety of TCM but also demonstrates the continuous progress made by China in the field of TCM safety supervision. Basis on this study, by systematically reviewing the development history of the detection standards for exogenous harmful residues in TCM and analyzing the revisions and updates of these detection standards in the Chinese Pharmacopoeia 2025 Edition, deeply explores the key points of the changes in the monitoring standards for exogenous harmful residues in TCM in the Chinese Pharmacopoeia 2025 Edition. Moreover, it interprets the future development directions of the detection of exogenous residues in TCM, aiming to provide a reference for the formulation of TCM safety supervision policies.

Objective To establish an individualized nomogram model and evaluate its efficacy to provide a possible evaluation basis for the prognosis of lower third and abdominal part of oesophageal adenocarcinoma (EAC). Methods Lower third and abdominal part of EAC patients from 2010 to 2015 were chosen from the SEER Research Plus Database (17 Regs, 2022nov sub). The patients were randomly allocated to the training cohort and the internal validation cohort with a ratio of 7∶3 using bootstrap resampling. The Cox proportional hazards regression analysis was used to determine significant contributors to overall survival (OS) in EAC patients, which would be elected to construct the nomogram prediction model. C-index, calibration curve and receiver operating characteristic (ROC) curve were performed to evaluate its efficacy. Finally, the efficacy to evaluate the OS of EAC patients was compared between the nomogram prediction model and TNM staging system. Results In total, 3945 patients with lower third and abdominal part of EAC were enrolled, including 3475 males and 470 females with a median age of 65 (57-72) years. The 2761 patients were allocated to the training cohort and the remaining 1184 patients to the internal validation cohort. In the training and the internal validation cohorts, the C-index of the nomogram model was 0.705 and 0.713, respectively. Meanwhile, the calibration curve also suggested that the nomogram model had a strong capability of predicting 1-, 3-, and 5-year OS rates of EAC patients. The nomogram also had a higher efficacy than the TNM staging system in predicting 1-, 3-, and 5-year OS rates of EAC patients. Conclusion This nomogram prediction model has a high efficiency for predicting OS in the patients with lower third and abdominal part of EAC, which is higher than that of the current TNM staging system.

Peripheral nerve injury refers to the impairment that occurs when the sens-ory nerves and motor nerves are damaged.Professor Zhang Hong has unique insights into the treatment of neurologically diseases in children.Based on the different manifestations of the disease,it is categorized under the traditional Chinese medicine concepts of"atro-phy syndrome","muscle injury"and"Bi syndrome".Professor Zhang believes that the disease is fundamentally rooted in the liver and kidneys,and that treatment should notonly address the acquired symptoms but also nurture the innate foundation.This article a-nalyze and summarize professor Zhang's clinical experience in using acupuncture,electroa-cupuncture,moving cupping,and moxibustion in the comprehensive treatment of peripheral nerve injury,providing a reference for clinical treatment of peripheral neuropathy in chil-dren.

Objective:To explore age-related variations in the angle of the cochlear basal turn using temporal bone CT, providing a reference for selecting the optimal Stenvers position radiographic projection angle in children and adults.Methods:The retrospective study included children and adults who underwent temporal bone CT scans at Beijing Tongren Hospital from November 2014 to April 2023. A total of 620 participants were included, including 368 males and 252 females. Patients were divided into 20 age-ralated groups: infants under one year old (3 to 11 months) were divided into monthly subgroups (9 groups); children and adolescents aged 1 to 18 years were grouped biennially (9 groups); adults were divided into two groups: 19 to 29 years and 30 to 40 years. Using multiplanar reconstruction (MPR) techniques, the CT images of the temporal bone were reformatted into oblique transverse sections to maximize the visibility of the cochlear basal turn.The cochlear basal turn angle was defined as the angle between the vertical axis of the cochlear basal turn and the mid-sagittal plane of the skull. Statistical analysis was performed to compare age-related differences in cochlear basal turn angles. Two additional patients were included to compare Stenvers position X-ray images with corresponding temporal bone CT scans, assessing the visibility of cochlear implant electrodes post-implantation.Results:Among infants aged 3 to 11 months, the cochlear basal turn angle was 29.4°±4.5°, with no significant differences observed between subgroups ( P>0.05). However, significant differences were found between infants (<1 year old) and the 1-2-year-old group compared to each age group from 3 to 40 years ( P<0.05). Additionally, the angles differed significantly between the 3-14-year-old groups and the 19-40-year-old groups ( P<0.05), whereas no significant differences were found among the remaining groups ( P>0.05). The visibility of the cochlear implant electrodes, appearing round in shape on standard Stenvers position X-ray images, closely resembled that observed in temporal bone CT scans. Conclusion:Age-related variations in the cochlear basal turn angle provide a valuable reference for optimizing Stenvers position radiography angles after cochlear implantation, improving the accuracy and quality of post-implantation imaging.

There exist risks of ionizing radiation in radiodiagnosis examinations. Implementing shielding protection following the optimization and as low as reasonably achievable (ALARA) principles represents a measure to reduce radiation doses to patients. The implementation of shielding protection in clinical practices should meet high requirements due to variations in the modalities and items in radiodiagnosis examinations, the characteristics and irradiation method of X-ray beams, the method of automatic selection of image quality and radiation dose-related parameters by imaging equipment, the radiation sensitivity of human tissues and organs. This review introduced the shielding products, methods and effects in various radiodiagnosis examinations, as well as the current status and challenges in their applications, aiming to provide a reference for future related research and clinical practices.

Objective:To investigate the epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) in Weinan City, Shaanxi Province, and study the predictive effect of the seasonal autoregressive integrated moving average (SARIMA) model.Methods:Relevant information on HFRS cases reported by the China Disease Prevention and Control Information System from January 2010 to August 2024 in Weinan City, as well as the epidemiological investigation data on clinical diagnosis and confirmed HFRS cases in Weinan City were collected. Epidemiological characteristics of HFRS were analyzed by descriptive epidemiological methods. At the same time, a SARIMA model was constructed based on the monthly incidence of HFRS from 2010 to 2023, the incidence of HFRS from January to August 2024 was used to test the simulation prediction effect, and the optimal model was used to predict the incidence of HFRS from September to December 2024.Results:A total of 4 373 HFRS cases were reported in Weinan City from 2010 to 2023, with an average annual incidence of 6.39/100 000. The incidence rate showed a cyclical fluctuation trend, reaching two peaks in 2012 (10.25/100 000) and 2021 (12.26/100 000), respectively. The incidence of HFRS presented a seasonal bimodal distribution, with the peak predominantly in autumn and winter (from October to January of the following year), accounting for 67.83% (2 966/4 373), and the peak in spring and summer (form May to July) accounting for 17.27% (755/4 373). HFRS cases were reported in all counties (cities and districts) of Weinan City, and the top 3 annual incidence rates were Huazhou District (17.84/100 000), Linwei District (16.10/100 000) and Huayin City (9.15/100 000). The age of onset was mainly concentrated in the age group of 15 - 59 years old, accounting for 68.31% (2 987/4 373). The male to female ratio was 2.96∶1.00 (3 268∶1 105). The main occupation was farmers, accounting for 82.07% (3 589/4 373). SARIMA (1, 0, 1) (2, 1, 1) 12 model was the optimal model for short-term prediction of HFRS incidence rate in Weinan City, and the residual difference was listed as white noise ( Q = 7.45, P = 0.878), the model could be used for disease prediction. The model was used to predict the incidence of HFRS from September to December 2024, and the predicted values of each month were 0.17/100 000, 0.59/100 000, 1.85/100 000 and 1.61/100 000, respectively. Conclusions:The epidemic range of HFRS in Weinan City is wide, and the incidence has obvious seasonality. The population are mainly males, young and middle-aged adults and farmers. The SARIMA (1, 0, 1) (2, 1, 1) 12 model constructed can be used for predicting the short-term incidence trend of HFRS in Weinan City.

Objective:To investigate the anticipatory grief and to explore its correlates among family caregiv-ers of patients with advanced gastrointestinal cancer.Methods:A total of 283 family caregivers of patients with ad-vanced digestive cancer in the gastroenterology ward of a hospital were assessed using the Perceptive Social Support Scale(PSSS),Simplified Coping Style Questionnaire(SCSQ),Mishel Illness Uncertainty Scale for Family Member(MULS-FM)and Anticipatory Grief Scale(AGS).Results:The median AGS score was 91.00(80.00,98.00).Multiple linear regression analysis revealed that the AGS scores were negatively correlated with PSSS scores(β=-0.21),positive coping scores(β=-0.43),education level(β=-4.99)and age(β=-4.23),but positively correlated with MULS-FM scores(β=0.24).Conclusion:Family caregivers exhibited moderate-to-high anticipato-ry grief,which significantly influenced by age,perceived social support,positive coping style,illness uncertainty and education level.

To explore the in vitro and in vivo synergistic effect of paclitaxel in combination with co-listin against MDREscherichia coli(E.coli)and the corresponding mechanism of synergism,we measured the MICs of PTX alone and combination of PTX+antimicrobial drugs on E.coli and Staphylococcus aureus(S.aureus)by broth microdilution method.Then,checkerboard method was used to determine the FICI of PTX+COL combination,and the antibacterial synergies of PTX and COL was further explored through analyzing the membrane permeability and efflux pump ac-tivity.The MICs results showed that the MIC values of PTX alone against E.coli(G5,E25)and S.aureus S238 were＞1 024 mg/L and 512 mg/L,respectively.Meanwhile,we found that the anti-bacterial activity of COL against E.coli could be significantly enhanced(MIC decreased by 4 to 8 times)when used in combination with PTX.The checkerboard test showed that the FICI values of PTX combined with COL for E.coli(G5,E25)were 0.31 and 0.29,respectively,indicating a synergistic antibacterial effect on these strains.The FICI values of PTX combined with COL for E.coli G21,S.aureus(S237 and S238)were 0.51,0.75 and 0.53,respectively,indicating additive effects on these strains.In the mouse abdominal infection model,the combination group could ex-tremely significantly reduce the bacterial burden of E.coli in abdominal compared to the COL or PTX alone group(P＜0.001).The analysis of membrane permeability and efflux pump activity showed that PTX combined with COL significantly increased the inner and outer membrane per-meability of E.coli(G5 and E25),and markedly inhibited the efflux pumping activity of E.coli,when compared that of PTX and COL alone(P＜0.01).The above results indicated that the com-bination of PTX and COL could exert a synergistic in vivo and in vitro antibacterial effect on COL-resistant E.coli through increasing bacterial membrane permeability and inhibiting efflux pump activity.This study provides the theoretical foundation for the development of a novel combi-nation regimen for the treatment of MDR E.coli infection.
