ObjectiveTo explore the mechanism through which Gantou Fumu decoction （GDFMT）-containing serum inhibits the activation of hepatic stellate cells. MethodsSerum pharmacology techniques were employed to prepare GDFMT-containing serum samples. Rat hepatic stellate cells （HSCT6） were randomly allocated into three groups： Control， penicillamine （90 mg·kg^-1）， and GDFMT （6.8 g·kg^-1）. Cell viability was assessed by the cell counting kti-8 （CCK-8） assay， intracellular ROS levels were determined by flow cytometry using the DCFH‑DA fluorescent probe and while extracellular collagen Ⅰ （ColⅠ） levels were quantified via enzyme linked immunosorbent assay （ELISA）. Intracellular α-smooth muscle actin （α-SMA） expression was visualized through immunofluorescence staining. Real-time polymerase chain reaction（Real-time PCR） and Western blot were performed to evaluate alterations in the expression of nuclear factor-erythroid 2-related factor 2 （Nrf2）， glutamate cysteine ligase， catalytic （GCLC）， glutamate-cysteine ligase， modifier subunit （GCLM）， Kelch-like ECH-associated protein 1 （Keap1）， NAD（P）H：Quinone oxidoreductase 1 （NQO1）， and heme oxygenase-1 （HO-1）. Genetic knockdown of Nrf2 was achieved through small interfering （siRNA） transfection to validate pathway specificity. ResultsCCK-8 data indicated that under the selected experimental conditions， culturing HSCT6 cells with 10% （volume fraction） GDFMT-containing serum for 48 h demonstrated equivalent effect in inhibiting HSCT6 cell proliferation compared with culturing HSCT6 cells with 10% （volume fraction） penicillamine-containing serum for 36 h， with no statistically significant difference between the two groups. After treatment of HSCT6 cells with siRNA-mediated Nrf2 gene transfection technique， the inhibitory effect of GDFMT on the activation process of HSCT6 cells was significantly weakened. After HSCT6 cells were cultured with GDFMT-containing serum for 48 h， the flow cytometry with a fluorescence probe showed that the content of reactive oxygen species （ROS） in the cells was significantly reduced. After the expression level of the Nrf2 gene in HSCT6 cells was knocked down by siRNA transfection， the content of ROS increased （P<0.01）， indicating that GDFMT significantly reduced the ROS level in activated HSCT6 cells， and this effect strictly depended on the integrity of the Nrf2 pathway. Quantitative analysis by ELISA showed that the synthesis of ColⅠ in the HSCT6 cell culture system treated with GDFMT-containing serum for 48 h was lower than that in the control group （P<0.01）. After the Nrf2 gene level of HSCT6 cells was knocked down by siRNA transfection， the ColⅠ concentration in the culture supernatant increased （P<0.01）. The results of α-SMA detection by IF method showed that compared with the normal group， GDFMT-containing serum reduced the expression of α-SMA （P<0.01） and the protein level of α-SMA in HSCT6 cells was increased （P<0.01） after siRNA-mediated Nrf2 silencing， suggesting that Nrf2 signaling pathway may be involved in regulating the phenotypic transformation process of the cells. Real-time PCR and Western blot results showed that GDFMT-containing serum reduced the protein level of α-SMA （P<0.01） and enhanced the gene and protein levels of Nrf2 in the nucleus and GCLC， HO-1， Keap1， GCLM， and NQO1 in the cytoplasm of HSCT6 cells （P<0.05， P<0.01）. After the Nrf2 gene level of HSCT6 cells was knocked down by siRNA transfection， the protein level of α-SMA was increased （P<0.01）， and the levels of GCLC， GCLM， Keap1， NQO1， and HO-1 were decreased （P<0.05， P<0.01）. These results indicated that GDFMT-containing serum successfully triggered the Nrf2 signaling pathway of HSCT6 cells. ConclusionThe anti-hepatic fibrosis effect of 10%GDFMT was equivalent to that of penicillamine. In addition， GDFMT can inhibit HSC activation and reduce oxidative stress damage by activating the Nrf2/antioxidant response element （ARE） pathway， as manifested by the up-regulated expression of Nrf2 and downstream antioxidant genes （GCLC， GCLM， HO-1， Keap1， and NQO1） and reduced secretion of ROS， α-SMA， and ColⅠ.

AIM:To analyze the association between mobile phone addiction and high myopia among college students.METHODS:We conducted a cross-sectional questionnaire survey in December 2022 on all students of a university in Shaanxi Province, and the questionnaire included socio-demographic characteristics, mobile phone addiction, high myopia, and lifestyle. Binary Logistic regression model was used to analyze the association between mobile phone addiction and high myopia among college students.RESULTS:A total of 19 952 college students were included. The prevalence of high myopia was 7.31%. The rate of mobile phone addiction was 25.68%, and the mobile phone addiction score was 37.59±13.38. The incidence of high myopia among college students with mobile phone addiction was higher than non-mobile phone addiction(P<0.001). After adjusting for socio-demographic characteristics and lifestyle, the risk of high myopia among college students with mobile phone addiction was 1.274 times(95%CI:1.131-1.434)higher than non-mobile phone addiction. For each point increase of total mobile phone addiction score, withdrawal symptoms score, salience score, social comfort score, and mood changes score, the risk of high myopia among college students increased by 0.9%(95%CI:1.005-1.013), 2.0%(95%CI:1.010-1.030), 2.6%(95%CI:1.010-1.043), 4.8%(95%CI:1.030-1.066), and 3.3%(95%CI:1.014-1.052), respectively.CONCLUSION:Mobile phone addiction is significantly associated with the increased risk of high myopia among college students, and early intervention of mobile phone use may reduce the risk of high myopia among college students.

Post-orgasmic illness syndrome (POIS) is a rare condition characterized by the rapid onset of extreme fatigue, flu-like symptoms, difficulty concentrating, depression, nasal congestion, rhinorrhea, itchy eyes, and other physical and psychological discomforts following ejaculation. This report presents the outcomes of two patients with POIS who underwent a two-year course of autologous seminal plasma subcutaneous cluster immunotherapy. Treatment efficacy was assessed using methods such as the symptom Visual Analogue Scale (VAS), the Union Physio-Psycho-Social Assessment Questionnaire (UPPSAQ)-70, and the Short Form 36 Health Survey (SF-36). The results suggest that autologous seminal plasma subcutaneous cluster immunother-apy may be a safe and effective therapeutic approach for POIS.

Objective:To compare the effects of manual acupuncture(MA),electroacupuncture(EA),and moxibustion on knee joint cartilage morphology,serum inflammatory factors interleukin(IL)-6 and IL-10,matrix metalloproteinase 13(MMP13),and intestinal flora composition in knee osteoarthritis(KOA)model rats.Methods:Forty male specific-pathogen-free Sprague-Dawley rats aged seven weeks were randomly divided into a normal group(n=8)and a KOA modeling group(n=32).The KOA model was established using sodium iodoacetate induction.The KOA modeling rats were further randomly divided into a model group,an MA group,an EA group,and a moxibustion group,with 8 rats in each group.In the MA,EA,and moxibustion groups,interventions targeting the right Futu(ST32)and Zusanli(ST36)were performed for 15 min,once every other day,for 14 sessions.The normal and model groups were bundled on the self-made fixation frame for 15 min.The rat knee joint diameter was measured on the 8th day of adaptive feeding,after successful modeling,and after the 14th intervention.Lequesne behavioral scoring was performed after successful modeling and after the 14th intervention.After the 14th intervention,hematoxylin-eosin(HE)staining and Masson staining were performed with the cartilage sections of the right knee joint.The pathomorphological changes of the rat joint cartilage were observed and quantified by Mankin's score.Enzyme-linked immunosorbent assay was used to detect the rat serum levels of IL-6,IL-10,and MMP13.Additionally,16S rDNA sequencing was used to detect the composition of rat fecal flora.Results:Compared to the normal group,the right knee joint diameter and the Lequesne score were significantly increased in the model group(P<0.01).Compared to the model group,the right knee joint diameter and the Lequesne score of rats in the MA,EA,and moxibustion groups were significantly reduced(P<0.01),with no significant differences among the three intervention groups(P>0.05).HE staining and Masson staining revealed disordered cartilage structure in the model group,which was improved following interventions in the MA group,EA group,and moxibustion group.Mankin's score was significantly higher in the model group versus the normal group(P<0.05)while significantly lower in the MA,EA,and moxibustion groups versus the model group(P<0.05).Serum analysis showed elevated IL-6 and MMP13 levels and reduced IL-10 level in the model group versus the normal group(P<0.05).Compared to the model group,the serum IL-6 level was significantly reduced(P<0.05),and the IL-10 level was significantly increased(P<0.05)in the MA,EA,and moxibustion groups,but without statistical differences among the three intervention groups(P>0.05);moreover,the MMP13 level in the moxibustion group was significantly lower than that in the model group(P<0.05).The alpha diversity analysis of intestinal flora showed no statistical difference in the number of operational taxonomic units(OTUs)and alpha diversity index among groups(P>0.05).Intestinal flora beta diversity analysis revealed significant differences among groups(P<0.05).Intestinal flora composition analysis showed significantly increased relative abundance of Lactobacillus(P<0.05)and significantly decreased relative abundance of Eubacterium_coprostanoligenes(P<0.05)in the model group compared to the normal group;compared to the model group,the relative abundances of Firmicutes,Lactobacillus,and Romboutsia in the MA,EA,and moxibustion groups were significantly reduced(P<0.05);the relative abundance of Bacteroidetes and Lachnospiraceae_NK4A136 in the MA group increased significantly(P<0.05);Bacteroidetes and Ruminococcaceaae_UGC-005 increased significantly in the moxibustion group(P<0.05).Conclusion:MA,EA,and moxibustion effectively reduced knee joint swelling,improved cartilage tissue morphology,optimized intestinal flora composition,down-regulated expression levels of serum pro-inflammatory factors IL-6 and MMP13,and increased expression level of anti-inflammatory factor IL-10 in KOA rats.Among them,moxibustion exhibited the most obvious regulatory effect on inflammatory factors.

Objective: Uterine cancer (UC) is a major cause of cancer-related deaths among women. This study assesses the global burden of UC from 1990 to 2021. Methods: Data from the Global Burden of Disease 2021 study were used to analyze UC incidence, mortality, and disability-adjusted life years (DALYs) across 204 countries.Age-standardized rates were evaluated by age and Socio-Demographic Index (SDI), with trends forecasted to 2036 using Bayesian models. Results: In 2021, the global incidence of UC reached 473,614 cases (95% uncertainty interval [UI]=4,29916–5,13667), with an age-standardized incidence rate of 5.41 per 100,000 (95% UI=4.90–5.87), showing an upward trend since 1990, particularly in high-SDI regions. However, the mortality rate in high SDI regions exhibited a declining trend, with an estimated annual percentage change (EAPC) of −0.25 (95% confidence interval=−0.42 to −0.08). Although the number of deaths globally has increased, the age-standardized mortality rate has decreased compared to 1990 (EAPC: −0.85). The global age-standardized DALYs also show a downward trend, except in high SDI and low-middle SDI regions. The highest incidence was observed among individuals aged 70–74 in 2021. By 2036, new cases are projected to rise, though incidence, mortality, and DALYs are expected to decline. Conclusion Regional disparities in the global UC burden highlight the need for tailored strategies, especially in low-income countries, to reduce its impact.

Cervical cancer (CC) is a significant cause of cancer-related deaths in women and ranks as the fourth most common malignant tumor worldwide. Cervical histopathology is currently the primary diagnostic method for confirming the presence of CC. Tumor markers and imaging techniques play crucial roles in monitoring treatment effectiveness and prognostic follow-up. Unfortunately, these traditional examination methods are invasive and often lack sensitivity and accuracy. Therefore, there is a need for a less invasive and more sensitive test to facilitate early diagnosis, efficacy evaluation, and prognostic monitoring of CC. In recent years, liquid biopsy has been developed as a new detection method. It involves analyzing tumor components released into the peripheral circulation, such as cell-free RNA, circulating tumor DNA, circulating tumor cells, tumor-educated platelets, and exosomes. Liquid biopsy offers advantages such as being less invasive, highly reproducible, and capable of real-time monitoring. Moreover, liquid biopsy can play a crucial role in the early diagnosis of CC, guiding targeted therapy, assessing prognosis, and evaluating treatment effectiveness.This review focuses on the value of liquid biopsy application in CC, detection markers, and detection methods. It also explores how liquid biopsy can be used in the detection, prognosis, and monitoring the progression of CC. The advantages and limitations of liquid biopsy in CC are analyzed to promote its application and improve the diagnosis and treatment of the disease.

Objective To investigate the distribution and antimicrobial resistance profiles of common pathogens isolated from cerebrospinal fluid(CSF)in CHINET program from 2015 to 2021.Methods The bacterial strains isolated from CSF were identified in accordance with clinical microbiology practice standards.Antimicrobial susceptibility test was conducted using Kirby-Bauer method and automated systems per the unified CHINET protocol.Results A total of 14 014 bacterial strains were isolated from CSF samples from 2015 to 2021,including the strains isolated from inpatients(95.3％)and from outpatient and emergency care patients(4.7％).Overall,19.6％of the isolates were from children and 80.4％were from adults.Gram-positive and Gram-negative bacteria accounted for 68.0％and 32.0％,respectively.Coagulase negative Staphylococcus accounted for 73.0％of the total Gram-positive bacterial isolates.The prevalence of MRSA was 38.2％in children and 45.6％in adults.The prevalence of MRCNS was 67.6％in adults and 69.5％in children.A small number of vancomycin-resistant Enterococcus faecium(2.2％)and linezolid-resistant Enterococcus faecalis(3.1％)were isolated from adult patients.The resistance rates of Escherichia coli and Klebsiella pneumoniae to ceftriaxone were 52.2％and 76.4％in children,70.5％and 63.5％in adults.The prevalence of carbapenem-resistant E.coli and K.pneumoniae(CRKP)was 1.3％and 47.7％in children,6.4％and 47.9％in adults.The prevalence of carbapenem-resistant Acinetobacter baumannii(CRAB)and Pseudomonas aeruginosa(CRPA)was 74.0％and 37.1％in children,81.7％and 39.9％in adults.Conclusions The data derived from antimicrobial resistance surveillance are crucial for clinicians to make evidence-based decisions regarding antibiotic therapy.Attention should be paid to the Gram-negative bacteria,especially CRKP and CRAB in central nervous system(CNS)infections.Ongoing antimicrobial resistance surveillance is helpful for optimizing antibiotic use in CNS infections.

Objective To investigate the antimicrobial resistance of clinical isolates from elderly patients(≥65 years)in major medical institutions across China.Methods Bacterial strains were isolated from elderly patients in 52 hospitals participating in the CHINET Antimicrobial Resistance Surveillance Program during the period from 2015 to 2021.Antimicrobial susceptibility test was carried out by disk diffusion method and automated systems according to the same CHINET protocol.The data were interpreted in accordance with the breakpoints recommended by the Clinical and Laboratory Standards Institute(CLSI)in 2021.Results A total of 514 715 nonduplicate clinical isolates were collected from elderly patients in 52 hospitals from January 1,2015 to December 31,2021.The number of isolates accounted for 34.3％of the total number of clinical isolates from all patients.Overall,21.8％of the 514 715 strains were gram-positive bacteria,and 78.2％were gram-negative bacteria.Majority(90.9％)of the strains were isolated from inpatients.About 42.9％of the strains were isolated from respiratory specimens,and 22.9％were isolated from urine.More than half(60.7％)of the strains were isolated from male patients,and 39.3％isolated from females.About 51.1％of the strains were isolated from patients aged 65-＜75 years.The prevalence of methicillin-resistant strains(MRSA)was 38.8％in 32 190 strains of Staphylococcus aureus.No vancomycin-or linezolid-resistant strains were found.The resistance rate of E.faecalis to most antibiotics was significantly lower than that of Enterococcus faecium,but a few vancomycin-resistant strains(0.2％,1.5％)and linezolid-resistant strains(3.4％,0.3％)were found in E.faecalis and E.faecium.The prevalence of penicillin-susceptible S.pneumoniae(PSSP),penicillin-intermediate S.pneumoniae(PISP),and penicillin-resistant S.pneumoniae(PRSP)was 94.3％,4.0％,and 1.7％in nonmeningitis S.pneumoniae isolates.The resistance rates of Klebsiella spp.(Klebsiella pneumoniae 93.2％)to imipenem and meropenem were 20.9％and 22.3％,respectively.Other Enterobacterales species were highly sensitive to carbapenem antibiotics.Only 1.7％-7.8％of other Enterobacterales strains were resistant to carbapenems.The resistance rates of Acinetobacter spp.(Acinetobacter baumannii 90.6％)to imipenem and meropenem were 68.4％and 70.6％respectively,while 28.5％and 24.3％of P.aeruginosa strains were resistant to imipenem and meropenem,respectively.Conclusions The number of clinical isolates from elderly patients is increasing year by year,especially in the 65-＜75 age group.Respiratory tract isolates were more prevalent in male elderly patients,and urinary tract isolates were more prevalent in female elderly patients.Klebsiella isolates were increasingly resistant to multiple antimicrobial agents,especially carbapenems.Antimicrobial resistance surveillance is helpful for accurate empirical antimicrobial therapy in elderly patients.

Objective To examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.
