ObjectiveTo explore the effects of Yimei Baijiang formula （YMBJF） on colitis-associated colorectal cancer （CAC） and the nuclear factor kappaB （NF-κB） signaling pathway in mice. MethodsSixty male Balb/c mice of 4-6 weeks old were randomized into 6 groups： Normal， model， capecitabine （0.83 g·kg^-1）， and low-， medium-， and high-dose （4.63， 9.25， 18.50 g·kg^-1， respectively） YMBJF. The mouse model of CAC was established by combining azoxymethane （AOM， 10 mg·kg^-1） and dextran sulfate sodium （DSS， 2%）. At the 5^th week after the start of modeling， the capecitabine group and the YMBJF groups were respectively administrated with the corresponding doses of drugs by gavage once a day for a total of 6 weeks. The body weights and general conditions of mice were measured and observed， and the disease activity index （DAI） was scored. The tumors in the colorectal tissue were counted， and the colorectal length was measured. The histological features of the colorectal tissue in each group of mice were observed by hematoxylin-eosin （HE） staining. The levels of inflammatory cytokines including interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α） in the serum were determined by enzyme-linked immunosorbent assay （ELISA）. The expression and localization of proliferating cell nuclear antigen-67 （Ki67）， proliferating cell nuclear antigen （PCNA）， and phosphorylated nuclear transcription factor-κB p65 （p-NF-κB p65） proteins were observed by immunohistochemistry （IHC）. The apoptosis of tumor cells was observed by the TUNEL assay. The mRNA levels of IL-6，IL-1β， TNF-α， nuclear transcription factor-κB p65 （NF-κB p65）， NF-κB inhibitor alpha （IκBα）， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax） in the colorectal tissue were quantified by Real-time polymerase chain reaction（Real-time PCR）. The protein levels of NF-κB p65， phosphorylated （p）-NF-κB p65， IκBα， p-IκBα， Bcl-2， and Bax in the colorectal tissue were determined by Western blot. ResultsCompared with the model group， each YMBJF group showed decreases in DAI and tumor number （P0.01）， and the medium-dose and high-dose YMBJF groups showed increases in colorectal length （P0.05）. In addition， each YMBJF group showed alleviated colorectal mucosal pathological injury， declined levels of IL-6， IL-1β， and TNF-α in the serum （P0.05）， reduced expression of Ki67 and PCNA （P0.01）， and down-regulated expression of p-NF-κB p65 （P0.05）. The apoptosis in the medium-dose and high-dose YMBJF groups increased （P0.01）. Each YMBJF group and the capecitabine group showed down-regulated mRNA levels of IL-1β， TNF-α， IL-6， NF-κB p65， and Bcl-2 （P0.05） and up-regulated mRNA levels of IκBα and Bax （P0.05）. The mRNA level of IκBα was up-regulated， and that of Bcl-2 was down-regulated （P0.05） in the high-dose YMBJF group. The protein levels of p-IκBα and Bcl-2 were down-regulated （P0.05） in each YMBJF group. The protein levels of IκBα and Bax were up-regulated in the medium-dose and high-dose YMBJF groups （P0.01）， while those of NF-κB p65 and p-NF-κB p65 were down-regulated （P0.05）. ConclusionYMBJF can reduce the number of tumors， reduce the levels of inflammatory factors， promote tumor cell apoptosis， and inhibit tumor cell proliferation by regulating the direct effector molecules of the NF-κB signaling pathway in the mouse model of CRC.

Myocardial infarction （MI） and osteoporosis （OP）， as two prevalent metabolic diseases with high morbidity and mortality rates， are respectively characterized by cardiovascular system dysfunction and bone homeostasis imbalance， collectively posing significant global public health challenges. While clinically often considered as independent diseases， recent studies have revealed shared pathological mechanisms between the two. This study initiated its exploration from the traditional Chinese medicine concept of the "heart-bone" axis， systematically analyzing the correlation between MI and OP from perspectives including hemodynamics， neuroendocrinology， calcium homeostasis， inflammation and vascular injury， as well as hormone levels. By discussing the pathological mechanisms of "heart disease affecting the bones and bone disease affecting the heart"， the study also elucidated advancements in both Western and traditional Chinese medicine treatments. The goal is to provide novel insights and methodologies for the prevention and treatment of "heart-bone comorbidities"， thereby facilitating comprehensive management of cardiovascular and skeletal diseases.

This paper systematically reviews the current status of integrated traditional Chinese and western medicine in the treatment of Helicobacter pylori （Hp） infection， as well as recent progress in clinical and basic research both in China and internationally. It summarizes the advantages of traditional Chinese medicine （TCM） in Hp infection management， including improving Hp eradication rates， enhancing antibiotic sensitivity， reducing antimicrobial resistance， decreasing drug-related adverse effects， and ameliorating gastric mucosal lesions. These advantages are particularly evident in patients who are intolerant to bismuth-containing regimens， those with refractory Hp infection， and individuals with precancerous gastric lesions. An integrated， whole-process management approach and individualized， staged comprehensive treatment strategies combining TCM and western medicine are proposed for Hp infection. Future prevention and control of Hp infection should adopt an integrative Chinese-western medical strategy， emphasizing prevention， strengthening primary care， implementing proactive long-term monitoring， optimizing screening strategies， and advancing the development of novel technologies and mechanistic studies of Chinese herbal interventions. These efforts aim to provide a theoretical basis and practical pathways for the establishment and improvement of Hp infection prevention and control systems.

Objective To evaluate the adaptability of the “Sen Zhang” master seed strain of tick-borne encephalitis virus(TBEV) during serial passaging in primary hamster kidney cells(PHKCs), screen tick-borne encephalitis(TBE) vaccine candidate strains, and perform serological identification and morphological observation of the virus.Methods The mouse brain-adapted “Sen Zhang” master TBEV strain was serially passaged 10 times in PHKCs. Plaque purification was conducted based on viral titration, and clones with E protein amino acid sequences identical to the parental strain were selected to undergo an additional 10 passages in PHKCs. The virus titers were monitored across generations, and the E protein amino acid sequences from the 1 st and 10 th passages were compared. Experimental vaccines were prepared by 2% formaldehyde inactivation. After 35 female Kunming mice were immunized three times, the mouse brain-derived virus was injected intraperitoneally, and the immunoprotective index was calculated based on the number of mouse deaths within 21 days.Serological identification was performed on the vaccine candidate strains, and the viral morphology was analyzed via transmission electron microscopy(TEM).Results The PHKC-adapted TBEV achieved a maximum titer of 8. 90 lgLD50/mL,stabilizing at(8. 85 ± 0. 059 6) lgLD_(50)/mL. Plaque assays demonstrated uniform visible circular plaques with sharp boundaries. Among 27 purified clones, #7, #14, and #17 retained E protein sequences identical to the parental strain. The virus titers remained 8. 60-8. 90 lgLD_(50)/mL stably during passaging. Clone #7 exhibited minimal E protein mutations and the highest immunoprotective index 2. 3 × 10~6. The serological neutralization index reached 3 162, and TEM revealed spherical enveloped particles with a diameter of about 50 nm, consistent with the vaccine strain.Conclusion A PHKCadapted TBEV strain with high genetic stability was successfully isolated, which meets the critical criteria of vaccine candidate strains and can elicit robust immune responses.

Objective To screen for potential targets of the anti-tuberculosis lead compound M6 using antibody microarray,express Mycobacterium smegmatis(Ms) target protein 2-C-methy1-D-erythriol 4-phosphate cytidylyl-transferase(IspD) in E.coli, and prepare its polyclonal antibodies, in order to provide experimental basis for in-depth study of the protein function and the development of new anti-tuberculosis drugs.Methods The minimum inhibitory concentration(MIC) of M6 against Ms and Corynebacterium glutamicum(Cg) was determined. The protein samples of Cg treated with M6 were captured and analyzed by antibody microarray, and the differential targets were identified and screened by mass spectrometry. The ispD gene of Ms was amplified by PCR and cloned into vector pET28a(+) to construct recombinant plasmid pET28a-ispD. The recombinant plasmid was transformed into E.coli BL21(DE3), and the optimal conditions for protein expression were determined by optimizing the induction temperature(16, 25, 33, 37 ℃) and IPTG concentration(0-1. 5 mmol/L). The recombinant IspD protein was purified by nickel column affinity chromatography. The purified recombinant IspD protein was used as immunogen combined with Freund's incomplete adjuvant to immunize 11 female BALB/c mice to prepare polyclonal antibodies. The titer of antiserum was determined by indirect ELISA, and the antibody specificity was detected by Western blot.Using the prepared polyclonal antibodies, the effect of M6 treatment on the expression level of Ms IspD protein was analyzed by Western blot.Results The MIC of M6 against Cg and Ms was 0. 5 and 32 μg/mL, respectively. IspD protein was one of the primary target proteins of M6. The recombinant expression plasmid pET28a-ispD was constructed correctly as identified by double enzyme digestion, and the IspD protein was expressed in E.coli. The optimal induction conditions were determined to be 1. 0 mmol/L IPTG, 16 ℃ for 14 h. After purification, the purity of recombinant IspD protein reached, and it could specifically bind to mouse anti-His tag monoclonal antibodies. The polyclonal antibodies against IspD protein achieved a high titer of 1∶102 400, which could specifically recognize IspD protein in recombinant bacterial lysate. The expression level of Ms IspD protein did not change significantly after M6 treatment.Conclusion In this study, the potential target IspD protein of M6 was successfully screened by antibody microarray screening, and Ms IspD protein was expressed in E.coli. The polyclonal antibodies against IspD were prepared by immunizing mice, providing essential experimental basic for further functional studies of this protein and the development of novel anti-tuberculosis drugs.

Objective: To evaluate the effect of community comprehensive management model intervention among patients with dyslipidemia, so as to provide the reference for optimizing community management strategies and improving the target achievement rate for blood lipids among this population. Methods: From May to June 2023, a multi-stage stratified random sampling method was employed to select patients with dyslipidemia from primary healthcare institutions in Jiaxing City, Zhejiang Province. Eligible participants were randomly assigned to either a control group or an intervention group. The control group received routine management, while the intervention group was subjected to a community comprehensive management model in addition to the routine care. Both groups were followed up for 24 months. Data on demographic characteristics, lifestyle behaviors, physical examination indices, and blood biochemical indicators were collected at baseline and after the intervention through questionnaires, physical examinations, and laboratory tests. Changes in obesity rate, central obesity rate, target achievement rates for blood lipids, blood pressure, and blood glucose, as well as lifestyle modifications, were analyzed. Differences between the two groups before and after the intervention were assessed using generalized estimating equations (GEE). Results: The control group consisted of 560 patients, including 303 females (54.11%) and 430 individuals aged ≥65 years (76.79%). The intervention group also included 560 patients, with 300 females (53.57%) and 431 individuals aged ≥65 years (76.96%). Before the intervention, no statistically significant differences were observed between the two groups in terms of gender, age, educational level, history of chronic diseases, and atherosclerotic cardiovascular disease risk stratification (all P>0.05). After 24 months of intervention, interaction effects between group and time were observed for obesity rate, central obesity rate, target achievement rate for blood lipids, target achievement rate for blood glucose, composite target achievement rate, physical activity rate, and medication adherence (all P<0.05). Specifically, the intervention group demonstrated lower rates of obesity and central obesity, and higher target achievement rate of blood lipids, target achievement rate of blood glucose, composite target achievement rate, physical activity rate, and medication adherence compared to the control group. Conclusion The community comprehensive management model contributed to improvements in multiple metabolic parameters (including body weight, waist circumference, blood lipids, and blood glucose) among patients with dyslipidemia, and was associated with increased physical activity rate and medication adherence.

Conclusions Varicella cases in Changchun City were mainly males and students aged 0-<20 years from 2020 to 2024. The peak incidence was mainly in winter. Chaoyang District was a high-risk area, with obvious spatial-temporal clustering.

Objective: To understand the prevalence of dental caries and its influencing factors among primary and middle school students in the Xinjiang Production and Construction Corps (hereinafter referred to as "the Corps"), so as to provide a reference for formulating targeted prevention strategies and promoting oral health of primary and middle school students. Methods: Primary and middle school students in the Corps were selected as survey subjects by a multi-stage stratified random cluster sampling method in September 2023. Basic information and dietary behaviors were collected through questionnaire surveys, and dental caries status was examined by oral health technicians. Multivariable logistic regression model was used to analyze the influencing factors of dental caries among primary and middle school students. Results: A total of 80 370 primary and middle school students were investigated, including 40 582 males (50.49%) and 39 788 females (49.51%). There were 37 608 primary school students (46.79%), 34 612 junior high school students (43.07%), and 8 150 senior high school students (10.14%). There were 26 669 students with dental caries, with a prevalence rate of 33.18%. Multivariable logistic regression analysis showed that the risk of dental caries was higher among female students (OR=1.170, 95%CI: 1.136-1.206), students in suburban counties (OR=1.212, 95%CI: 1.166-1.258), boarding students (OR=1.306, 95%CI: 1.257-1.357), and those with a frequency of fried food intake ≥1 time per day (OR=1.175, 95%CI: 1.084-1.273). Conversely, the risk of dental caries was lower among middle school students (OR=0.542, 95%CI: 0.524-0.560), high school students (OR=0.661, 95%CI: 0.620-0.705), and those with a frequency of vegetable intake ≥1 time per day (1 time per day, OR=0.900, 95%CI: 0.838-0.967), (≥2 time per day, OR=0.879, 95%CI: 0.819-0.944), and those who sometimes ate breakfast (OR=0.907, 95%CI: 0.874-0.942). Conclusions The prevalence of dental caries among primary and middle school students in the Corps is relatively high, and is influenced by various factors such as gender, school stage, area, boarding status, and dietary behaviors. It is suggested to strengthen oral health knowledge education among students, conduct regular oral health examinations, and improve the overall level of oral health.

BACKGROUND Individualized positive end-expiratory pressure (PEEP) titration is a crucial technique in mechanical ventilation therapy for acute respiratory distress syndrome (ARDS) patients with intra-abdominal hypertension (IAH). This study aimed to evaluate the effectiveness of electrical impedance tomography (EIT)-guided PEEP titration in this population. METHODS: This prospective study enrolled 36 ARDS patients, including 22 patients with IAH and 14 without IAH. All the patients underwent EIT-guided PEEP titration at the intersection point between alveolar overdistension and collapse during a decremental PEEP trial. The changes in pulmonary ventilation distribution, respiratory mechanics and hemodynamics during the titration process were observed. RESULTS: After EIT-guided PEEP titration was performed, the PEEP, peak inspiratory pressure and plateau pressure increased significantly (P<0.05). Furthermore, no significant differences were observed in respiratory system compliance, tidal volume, driving pressure, or the 4*DP+RR index between the two groups (P>0.05). The mechanical power increased in the non-IAH (NIAH) group after PEEP titration (P<0.05). Ventilation in gravity-dependent lung regions significantly increased (P<0.05), and the oxygenation index (PaO2/FiO2) improved significantly (P<0.05) in both groups. However, blood pressure, heart rate, respiratory rate, central venous pressure, and lactate levels did not significantly change. In the IAH group, the PaO2/FiO2 ratio improved less than that in the NIAH group did (P<0.05). CONCLUSION: In our study, individualized PEEP titration guided by EIT improved oxygenation in ARDS patients with concomitant IAH without significantly affecting hemodynamics. The presence of IAH may limit the improvement of oxygenation during EIT-guided PEEP titration.

ObjectiveThis study aims to explore the mechanism by which Yishen Huoxue Tongqiao Formula improves metabolism-neuroplasticity and treats unilateral vestibular labyrinth destruction by regulating the metabolic balance of glutamate （Glu）/γ-aminobutyric acid （GABA）. Methods48 Sprague-Dawley （SD） adult rats were randomly divided into the sham operation group， model group， Yishen Huoxue Tongqiao Formula groups with low， medium， and high doses （9.20， 18.39， 36.78 g·kg^-1）， and betahistine group （1.62 mg·kg^-1）. A unilateral vestibular labyrinth destruction （vestibular dysfunction） model was established by intratympanic injection of chloroform into the right ear， while the control group received intratympanic injection of normal saline. Drugs were administered once daily for seven consecutive days. During the period， behavioral tests were performed to evaluate the behaviors of rats after unilateral vestibular labyrinth destruction. Hematoxylin-eosin （HE） staining and Nissl staining were used to observe the neuronal morphology in the medial vestibular nucleus. Golgi staining was employed to assess the number of dendritic spines of neurons in the medial vestibular nucleus. Ultra-performance liquid chromatography-tandem mass spectrometry （LC-ESI-MS/MS） was utilized to detect Glu/GABA. Immunofluorescence and immunohistochemistry were used to detect the expressions of neuronal nuclei （NeuN）， growth-associated protein 43 （GAP-43）， and glial fibrillary acidic protein （GFAP）. Western blot and real-time fluorescent quantitative polymerase chain reaction （Real-time PCR） were applied to determine the expressions of glutamate-immunoreactive （Glu-IR）， GABA， GFAP， postsynaptic density protein 95 （PSD-95）， and GAP-43. ResultsCompared with the sham operation group， the model group presented with head deviation， balance disorder， increased tail suspension score， nuclear consolidation of medial vestibular nerve neurons， and decreased Nissl bodies （P<0.01）. The number of dendritic spines in neurons and NeuN-positive cells decreased. The content of Glu decreased. The content of GABA increased （Glu/GABA decreased）. The expression of GAP-43 was down-regulated， and GFAP was up-regulated （P<0.05， P<0.01）. The expressions of Glu-IR， PSD-95， and GAP-43 proteins， as well as Glu-IR mRNA decreased， while the expressions of GABA and GFAP proteins and mRNA increased （P<0.05， P<0.01）. Compared with those in the model group， the head deviation， imbalanced behavior， and tail suspension scores in each treatment group decreased， with alleviated neuronal injury and recovered Nissl bodies （P<0.01）. The number of dendritic spines of neurons increased， and the number of NeuN-positive cells rebounded. The content of Glu increased， and the content of GABA decreased （Glu/GABA increased）. GFAP was down-regulated， and GAP-43 was up-regulated （P<0.05， P<0.01）. The expressions of Glu-IR， PMD-95， and GAP-43 proteins， as well as Glu-IR mRNA increased， while the expressions of GABA and GFAP proteins and mRNA decreased. The effect was more significant in the high-dose group （P<0.01）. ConclusionThe Yishen Huoxue Tongqiao Formula can alleviate vestibular dysfunction， and its mechanism may be associated with regulating the metabolic balance of Glu/GABA， mitigating neural damage， improving synaptic plasticity （promoting GAP-43 expression and inhibiting GFAP expression）， and facilitating vestibular compensation.
