ObjectiveTo investigate the therapeutic effect of wall-broken ganoderma lucidum spore powder （GLS） on a mouse model of hepatocellular carcinoma and to explore its underlying mechanism. MethodsFifty 2-week-old C57BL/6J mice were divided into a control group， a model group and low， medium and high-dose GLS groups（0.25， 0.5， 1.0 g/kg ）， with 10 mice in each group. A DEN/CCL₄ mouse hepatocellular carcinoma model was established， and GLS was administered by gavage starting from the 8th week， once a day for 14 weeks. At the end of the final administration， the number of liver nodules was observed ， and the serum alpha-fetoprotein （AFP） was detected using enzyme-linked immunosorbent assay. The content of catalase （CAT） in serum and liver tissue was determined by ammonium molybdate method. The content of reduced glutathione （GSH） in serum and liver tissue was measured by microplate assay. The content of glutathione peroxidase （GSH-PX） in serum and liver tissue was detected by colorimetric method. Immunohistochemistry （IHC-P） was employed to detect the protein expression of proliferating cell nuclear antigen （PCNA）. R eal-time fluorescence quantitative polymerase chain reaction was utilized to detect the relative expression of nuclear factor E2-related factor 2 （Nrf2）， Kelch-like epichlorohydrin-associated protein 1 （Keap1）， NAD（P）H quinone oxidoreductase 1 （Nqo1）， heme oxygenase-1 （Ho-1） and glutamate cysteine ligase catalytic subunit （Gclc） mRNA. ResultsCompared with the control group， the content of serum AFP were significantly higher in the model group （P<0.01）， while the contents of CAT， GSH and GSH-PX in liver and serum were significantly lower in the model group （P<0.01）. The relative expression of Keap1 and Nqo1 mRNA was significantly higher （P<0.01）， the relative expression of Nrf2， Ho-1， Gclc mRNA relative expression was significantly lower （P<0.01）， and the positive expression rate of PCNA was significantly higher （P<0.01）. Compared with the model group， the total number of liver nodules and content of serum AFP in the administered group were significantly lower （P<0.01）， and the contents of CAT， GSH， and GSH-PX in the liver and serum of mice significantly increased （P<0.05 or P<0.01）. The expression of Keap1 and Nqo1 mRNA significantly decreased （P<0.05）. The expression of Nrf2， Ho-1 and Gclc mRNA significantly increased （P<0.05）， and positive expression rate of PCNA significantly decreased （P<0.01）. ConclusionGLS has a significant protective effect on DEN/CCL4 -induced mouse hepatocellular carcinoma model， and the mechanism of action is related to the regulation of oxidative stress in mouse liver.

There is an interation and synergistic effect between DM and Hs-CRP to promote the incidence of digestive system malignancy.

AIM:To investigate the effects of ethylisopropylamiloride(EIPA),an inhibitor of Na+/H+ex-changer 1(NHE1),on the proliferation,migration,invasion,cell cycle and apoptosis of hepatocellular carcinoma cells,and to explore its mechanisms.METHODS:The human hepatocellular carcinoma cell line Huh7 was cultured in vitro,and treated with different concentrations of EIPA.The mRNA and protein expression of NHE1 in Huh7 cells was assessed by RT-qPCR and Western blot.The proliferation of Huh7 cells was examined by kFluor488-EdU staining.The migration and invasion of Huh7 cells were assessed by Transwell assays.The cell cycle distribution and apoptosis of these cells were detected by flow cytometry.Moreover,the intracellular pH was measured via the PTI high-speed ion imaging system.RE-SULTS:Treatment with EIPA significantly suppressed the mRNA and protein expression of NHE1(P＜0.01).It signifi-cantly inhibited the proliferation,migration and invasion of Huh7 cells(P＜0.05 or P＜0.01),promoted their apoptosis(P＜0.01),and caused significant S-phase arrest(P＜0.01).It also significantly reduced the intracellular pH of Huh7 cells.CONCLUSION:The NHE1 inhibitor EIPA regulates the intracellular pH by inhibiting the expression and function of NHE1,which consequently affects the proliferation,migration,invasion,cell cycle,and apoptosis of Huh7 cells.There-fore,NHE1 may be a potential target for the treatment of hepatocellular carcinoma.

Objective:To investigate the predictive value of different obesity indicators for colorectal cancer (CRC) risk in different gender populations.Methods:This observational study was conducted within the Kailuan Study (Registration Number: ChiCTR-TNC-11001489). From July 2006 to October 2007, a total of 101,510 employed and retired individuals underwent health examinations, including gastrointestinal disease screening, hematological tests, and questionnaires, at Kailuan General Hospital and its 10 affiliated hospitals. After excluding those with incomplete data, 93,606 participants were included in this study and divided into male (74 852) and female (18 754) groups. CRC incidence was collected through physical examinations and questionnaires every two years. Each participant's follow-up period began at the time of the questionnaire and ended upon CRC diagnosis, death, or December 31, 2021. Body Mass Index (BMI), waist circumference, waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR) were quartiled (Q1, Q2, Q3, Q4), with Q1 serving as the control group. After adjusting for traditional risk factors such as age, total cholesterol, triglycerides, diabetes, hypertension, smoking status, alcohol consumption, and physical exercise, Cox regression models were used to calculate the correlations between BMI, waist circumference, WHR, WHtR, and CRC incidence in both male and female populations.Results:The age of all patients was (51±12) years, BMI was (25.06±3.49) kg/m 2, waist circumference was (86.94±9.97) cm, hip circumference was (97.30±8.81) cm, WHR was 0.89±0.07, and WHtR was 0.52±0.06.Female participants had significantly lower BMI, waist circumference, WHR, and WHtR compared to males, with statistically significant differences (all P<0.05). The mean follow-up duration for all participants was 15.01 (14.10±2.66) years, during which 718 CRC cases were identified, including 626 males (0.83%) and 92 females (0.49%). Cox proportional hazards models for males showed that CRC risk increased with waist circumference from Q3 (HR=1.43, 95%CI: 1.13-1.79, P=0.003) to Q4 (HR=1.45,95%CI: 1.14-1.82, P=0.002). Similarly, CRC risk increased with WHR from Q3 (HR=1.22, 95%CI: 1.01-1.53, P=0.007) to Q4 (HR=1.43, 95%CI: 1.14-1.79, P=0.002) and with WHtR from Q3 (HR=1.37, 95%CI: 1.08-1.74, P=0.009) to Q4 (HR=1.68, 95%CI: 1.33-2.12, P<0.001). For females, CRC risk increased with waist circumference from Q2 (HR=2.37, 95%CI: 1.20-4.67, P=0.012) to Q3 (HR=2.42, 95%CI: 1.21-4.84, P=0.013) but decreased in Q4 ( HR=2.08, 95%CI: 1.02-4.25, P=0.043). CRC risk increased significantly with WHR from Q2 (HR=2.20, 95%CI: 1.11-4.39, P=0.024) to Q3 (HR=2.89, 95%CI: 1.48-5.67, P=0.002) in females but was not statistically significant in Q4 ( P=0.074). Among females, CRC risk also increased significantly with WHtR in Q2 (HR=2.30, 95% CI: 1.16-4.56, P=0.017) and Q4 (HR=2.64, 95%CI: 1.32-5.29, P=0.006). There were no statistically significant differences in CRC risk associated with BMI in either male or female populations (both P>0.05). Conclusion:Waist circumference, WHR, and WHtR were better predictors of CRC risk than BMI in both male and female populations.

OBJECTIVE To preliminarily assess the horizontal sound localization and its influencing factors in patients with unilateral sudden sensorineural hearing loss during the acute phase.METHODS The azimuth discrimination test and azimuth identification test were completed,with the speech sound(65 dB SPL)as the stimulus.The minimum audible angle(MAA)and root-mean-square error(RMSE)were obtained,and the RMSE of the affected side and the healthy side were calculated respectively.According to the WHO(2021)hearing loss classification criteria,the data were analyzed based on the pure-tone average(PTA)of the affected ear.And the best resident hearing at each frequency of the affected ear was recorded.RESULTS The performance of the unilateral sudden sensorineural hearing loss patients in the sound localization varied greatly.Some performed close to the normal level,while others completely lost the ability to localize sound.The RMSE of the moderate hearing loss group(≥35 dB HL)was significantly higher than that of the normal hearing group(P<0.01),the MAA of the moderate to severe hearing loss group(≥50 dB HL)showed statistically significant differencescompared with normal hearing group(P<0.001).The RMSE of the affected side of patients in the severe and above hearing loss group was significantly larger than that of the healthy side.Regression analysis showed that the best resident hearing at each frequency of the affected ear was the most significant factor affecting MAA(R2=0.572,P<0.001)and RMSE(R2=0.768,P<0.001).CONCLUSION The horizontal sound localization of unilateral sudden sensorineural hearing loss patients in the acute phase varies greatly.When the PTA of the affected side reaches moderate hearing loss,the localization ability is significantly lower than that of normal-hearing individuals.The best resident hearing at each frequency of the affected ear is the key factor affecting the localization ability.

Cancer is a highly deadly disease, with breast cancer, cervical cancer, endometrial cancer, and ovarian cancer being the most prevalent in women. However, traditional cancer treatments present challenges due to their strong toxic side effects and adverse reactions. Numerous studies have demonstrated that natural products derived from various plants possess therapeutic and preventive properties against cancer. These phytochemicals have been extensively investigated as a potential alternative to conventional chemotherapy drugs, owing to their safety and efficacy. This article provides a comprehensive review of the recent advances in the chemoprevention and mechanisms of phytochemicals against the four major female cancers. The focus will be on how these phytochemicals regulate cancer cell proliferation, apoptosis, invasion, and metastasis to impede cancer progression. Given their extensive clinical applications, phytochemicals hold great promise in the field of cancer treatment. It hopes that this review will inspire more researchers to explore the potential of these natural compounds in combating female cancers.

Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

Background Kurtosis reflecting noise's temporal structure is an effective metric for evaluating noise-induced hearing loss (NIHL), and its threshold is still unclear. Objective To explore the energy range of kurtosis and the threshold of NIHL induced by kurtosis in this energy rangeMethods Using cross-sectional design, 4631 noise-exposed workers in manufacturing industry were selected. The hearing loss and noise exposure data of each worker were collected. Logistic regression model was used to establish the dose-response relationship between noise exposure and hearing loss and estimate the range of energy effects. Restricted cubic spline model was utilized to analyze the dose-response relationship curves of kurtosis to noise-induced hearing loss (NIHI) and high-frequency noise-induced hearing loss (HFNIHL) under different 8 h equivalent sound levels (L_{EX,8 h}), as well as to estimate the kurtosis effect threshold. Results The logistic regression model analysis showed that the prevalence of NIHI and HFNIHL increased significantly with increase of L_{EX,8 h} for steady noise; when L_{EX,8 h} of non-steady noise was 80-100 dB(A), the risk of hearing loss increased with an increase in kurtosis (P<0.05). The restricted cubic spline model showed that when L_{EX,8 h} of non-steady noise was 0-80 dB(A) or >100 dB(A), there was no significant relationship between kurtosis and NIHI or HFNIHL. When L_{EX,8 h} was 80-100 dB(A), there was a significant nonlinear dose-response relationship between kurtosis and NIHL or HFNIHL (P <0.001), and kurtosis > 28.08 exerted effect in elevating NIHI or HFNIHL. Conclusion The effect threshold of kurtosis on NIHL is 28.08 when non-steady noise levels are in the range of 80-100 dB(A). The effect threshold of kurtosis needs further verification.
