BACKGROUND:Physiotherapy is very important for the recovery after anterior cruciate ligament reconstruction.In recent years,many doctors are optimizing the physical rehabilitation program after anterior cruciate ligament reconstruction.However,there is still a lack of efficient rehabilitation training after anterior cruciate ligament reconstruction. OBJECTIVE:To investigate the effect of vibration therapy combined with suspension training on movement and knee joint function after anterior cruciate ligament reconstruction. METHODS:A total of 80 patients undergoing first unilateral anterior cruciate ligament reconstruction at the Affiliated Sport Hospital,Shanghai University of Sport were randomly divided into vibration therapy group(n=40)and vibration therapy+suspension training group(n=40).In the vibration therapy group,vibration therapy(10 minutes each,once a day,6 times per week)was performed at the 13th week after anterior cruciate ligament reconstruction.Patients in the vibration therapy+suspension training group were treated with vibration therapy(10 minutes each,once a day,6 times per week)and suspension training(twice a week)at the 13th week after anterior cruciate ligament reconstruction.Training in each group was performed for 8 weeks.Knee joint function was evaluated by knee joint Lysholm score before and 8 weeks after training.The symmetry index was evaluated by the isokinetic muscle strength evaluation training system.The balance test system was used to evaluate the average trace error difference of the bilateral multi-axes. RESULTS AND CONCLUSION:Compared with those before training,the knee Lysholm score and the knee extension and flexion symmetry indexes increased(P<0.05),and the average trace error difference decreased after training(P<0.05).Compared with the vibration therapy group,the knee Lysholm score in the vibration therapy+suspension training group increased(P<0.05),the knee extension and knee flexion symmetry index increased(P<0.05),and the average trace error difference decreased(P<0.05).To conclude,compared with vibration therapy training alone,vibration therapy combined with suspension training can significantly improve knee joint function,increase muscle strength and symmetry,and improve balance stability in patients undergoing anterior cruciate ligament reconstruction.

As a new type of model organism, zebrafish is gradually gaining prominence in the field of scientific research. The unique biological characteristics and advantages of zebrafish make them play an increasingly important role in the quality evaluation of traditional Chinese medicine. Compared with other common experimental animals, zebrafish have a fast reproductive and growth speed and high embryo transparency, making them an ideal model for evaluating the quality of traditional Chinese medicine. This provides a new perspective and method for research on traditional Chinese medicine. With the growing global interest in traditional Chinese medicine, it has become crucial to find scientific and accurate methods to evaluate the quality and effectiveness of traditional Chinese medicine. The introduction of the zebrafish model has brought new breakthroughs in the quality evaluation of traditional Chinese medicine. To further promote the application of zebrafish in evaluating the quality of traditional Chinese medicine, this article systematically searched and sorted out the previous studies related to the application of zebrafish for this purpose since 2023. The commonly used disease models and indicators of zebrafish in evaluating the effectiveness of traditional Chinese medicine, as well as the mechanism of zebrafish in exploring the active ingredients of traditional Chinese medicine, were primarily reviewed. The application of zebrafish in evaluating the safety of traditional Chinese medicine and the typical examples in ensuring the quality of traditional Chinese medicine were demonstrated. The limitations encountered by zebrafish models in evaluating the quality of traditional Chinese medicine were highlighted. The resolution of these problems will help further improve the accuracy and reliability of zebrafish in evaluating the quality of traditional Chinese medicine. The article discussed the evaluation of effectiveness, safety, and quality control of zebrafish applied in traditional Chinese medicine, so as to provide a reference for establishing standards for traditional Chinese medicine and promoting its modernization in the future.

ObjectiveBased on the zebrafish model, the hepatotoxicity and anti-osteoporotic activity of evodiamine (EVO) were studied. The mechanism of EVO in treating osteoporosis was explored by using network pharmacology and real-time polymerase chain reaction(Real-time PCR). MethodsThree days after fertilization (3 dpf), zebrafish were randomly selected and exposed to different concentrations of EVO solution for 96 hours. The mortality rate of zebrafish at different concentrations was calculated at the exposure endpoint, and a "dose-toxicity" curve was drawn. The 10% lethal concentration (LC10) was calculated. Liver phenotype, acridine orange staining, and pathological tissue sections of liver-transgenic zebrafish [CZ16 (gz15Tg.Tg (fabp 10a: ds Red; ela31: EGFP))] were used to confirm hepatotoxicity of EVO. On this basis, prednisolone was used to create a model of osteoporosis in zebrafish. The skull development, area of the skull stained by alizarin red, and cumulative optical density were used as indicators to evaluate the anti-osteoporotic activity of EVO in a safe dose. Based on network pharmacology, the mechanism of action of EVO in the treatment of osteoporosis was predicted and verified through Real-time PCR. ResultsThe LC10 of EVO on zebrafish (7 dpf) was determined to be 0.4 mg·L-1. Compared with the control group, sublethal concentrations (

ObjectiveTo investigate the effect of folic acid-modified crebanine polyethylene glycol-polylactic acid hydroxyacetic acid copolymer(PEG-PLGA) nanoparticles(FA-Cre@PEG-PLGA NPs, hereinafter referred to as NPs) combined with ultrasonic irradiation on subcutaneous tumor of liver cancer in Kunming(KM) mice. MethodsEighty-four healthy male KM mice were utilized to establish a subcutaneous tumor model of mouse hepatocellular carcinoma with H22 cells, then mice were randomly divided into model group, placebo group, hydroxycamptothecin group(8 mg∙kg-1), low, medium and high dose crebanine raw material groups(2, 2.5, 3 mg∙kg-1, hereinafter referred to as the low, medium and high dose crebanine groups, respectively), low, medium and high dose NPs groups(2, 2.5, 3 mg∙kg-1), and low, medium and high dose NPs combined with ultrasonic irradiation groups(2, 2.5, 3 mg∙kg-1, hereinafter referred to as the low, medium and high dose combination groups, respectively). The corresponding doses of drugs were administered via tail vein injection, the model group received no treatment, while the placebo group was injected with an equivalent amount of normal saline. Dosing was conducted for a total of 10 times on alternate days. The body mass of the mice was monitored, and parameters such as body mass change rate, thymus index, spleen index, tumor volume, tumor weight, relative tumor growth rate(T/C), and tumor inhibition rate(TGI) were calculated. Pathological changes in liver and kidney tissues as well as the tumor were observed by hematoxylin-eosin(HE) staining. Additionally, the levels of aspartate aminotransferase(AST), alanine aminotransferase(ALT), blood urea nitrogen(BUN) and creatinine(CREA) in serum of mice were detected by biochemical method. Furthermore, the effect of ultrasound on the distribution of NPs in subcutaneous tumors of mouse hepatocellular carcinoma was observed by in vivo imaging technique. ResultsAmong different treatment methods, the combination of NPs and ultrasound irradiation had the best therapeutic effect. Compared with the model group, the body mass growth rates of mice in the medium and high combination groups decreased, while the thymus index and spleen index increased, but there was no statistically significant difference in serum AST, ALT, BUN and CREA levels, indicating that NPs combined with ultrasound irradiation had little effect on the normal physiological state of the body, oth groups had TGI>40% and T/C<60%, indicating a clear anti-tumor effect. Pathological analysis showed that compared with the NPs groups, the combination groups exhibited varying degrees of necrosis in tumor cells, accompanied by less damage to the liver and kidneys. In vivo imaging of small animals showed that compared with the high dose NPs group, the high dose combination group had stronger tumor targeting ability(P<0.01). ConclusionNPs combined with ultrasonic irradiation can not only effectively targeted the drug to the tumor site, inhibit the subcutaneous tumor growth of mouse liver cancer, but also decrease damage to liver and kidney tissues.

Objective:
To investigate the attention cognitive function and symptom correlations of school aged children with attention deficit hyperactivity disorder (ADHD)using event related potential (ERP) technology, so as to provide references for the early diagnosis of children with ADHD.
Methods:
A total of 52 school aged children diagnosed with ADHD at the outpatient department of the Third Affiliated Hospital of Zhengzhou University from September 2022 to September 2024 and 50 age /sex matched healthy controls were selected. The ERP experiment adopted the auditory Oddball task to conduct comparative analyses of the amplitude and latency of the mismatch negative(MMN) at the Fz, Cz, and Pz points of the scalp electrode and the P3a component respectively. The symptom assessment scales adopted the Swanson,Nolan,and Pelham-Ⅳ Rating Scale (SNAP-Ⅳ) and the Parent Symptom Questionnaire (PSQ), which were filled out by the parents. Spearman correlation analysis was used to analyze the correlation between ERP components and symptoms in schoolaged children with ADHD.
Results:
The latency of MMN components in the healthy control group on the Fz lead was (188.30±2.06)ms, and the amplitude was (-15.54±1.35)μV; the latency of the P3a component on the Pz lead was (312.82±7.80)ms, and the amplitude was (3.80±0.18)μV. The latency of MMN components in the ADHD group on the Fz lead was (188.94±1.39)ms, and the amplitude was (-14.78±1.40)μV; the latency of the P3a component on the Pz lead was (317.21±5.65)ms, and the amplitude was (3.70±0.13)μV. Compared with normal children, the MMN of children with ADHD had smaller amplitudes in the Fz and Cz leads, and the P3a had greater latency and smaller amplitudes in the Cz and Pz leads ( t =2.79,2.20;-2.04,-3.25;2.35,3.21, P <0.05). Correlation analysis showed that the latency of MMN in children with ADHD was positively correlated with the inattention score in the SNAP-Ⅳ( r =0.22), and the amplitude of MMN was negatively correlated with the inattention score in the SNAP-Ⅳ and the learning problem score in PSQ ( r = -0.26 , -0.34)( P <0.05). The latency of P3a was positively correlated with the scores of inattention in the SNAP-Ⅳ and the score of learning problems in the PSQ ( r =0.26 ,0.24); the amplitude of P3a was negatively correlated with the scores of attention deficit and hyperactivity/impulsivity in the SNAP-Ⅳ and the scores of learning problems and impulsivity/hyperactivity in the PSQ( r = -0.26 , -0.22, -0.25,-0.32)( P <0.05).
Conclusions
School aged ADHD children exhibit abnormal MMN/P3a components, indicating attention related cognitive dysfunction. Symptoms such as inattention, learning problems and hyperactivity/impulsivity in children with ADHD are related to abnormal components of MMN and P3a.

OBJECTIVE To investigate the targeting effect of folic acid-modified crebanine nanoparticles (FA-Cre@PEG- PLGA NPs, hereinafter referred to as “NPs”) combined with ultrasound irradiation on M109 cells in vitro and in vivo after administration, and explore the anti-tumor mechanism. METHODS CCK-8 assay was used to detect the inhibitory effect of NPs combined with ultrasound irradiation on the proliferation of M109 cells, and the best ultrasound time was selected. Using human lung cancer A549 cells as a control, the targeting of NPs combined with ultrasound irradiation to M109 cells was evaluated by free folic acid blocking assay and cell uptake assay. The effects of NPs combined with ultrasound irradiation on the migration, invasion, apoptosis, cell cycle and reactive oxygen species (ROS) levels of M109 cells were detected by cell scratch test, Transwell chamber test and flow cytometry at 1 h after 958401536@qq.com administration; the changes of mitochondrial membrane potential (MMP) were observed by fluorescence inverted microscope. A mouse subcutaneous tumor model of M109 cells was constructed, and the in vivo tumor targeting of NPs combined with ultrasound irradiation was investigated by small animal in vivo imaging technology. RESULTS NPs combined with ultrasound irradiation could significantly inhibit the proliferation of M109 cells, and the optimal ultrasound time was 1 h after administration. The free folic acid could antagonize the inhibitory effect of NPs on the proliferation of M109 cells, and combined with ultrasound irradiation could partially reverse this antagonism. Compared with A549 cells, the uptake rate of NPs in M109 cells was significantly higher (P<0.01), and ultrasound irradiation could promote cellular uptake. NPs combined with ultrasound irradiation could inhibit the migration and invasion of M109 cells and block the cell cycle in the G0/G1 and G2/M phases. Compared with control group, the apoptosis rate of M109 cells and ROS level were increased significantly (P<0.01), while the MMP decreased significantly (P<0.01) in the different concentration (100, 200, 300 μg/mL) groups of M109 cells. Compared with the mice in non-ultrasound group, the fluorescence intensity and tumor-targeting index of the tumor site in the 0 h ultrasound group were significantly enhanced (P<0.05 or P<0.01). CONCLUSIONS NPs combined with ultrasound irradiation have a strong targeting effect on M109 cells in vitro and in vivo, the anti-tumor mechanism includes inhibiting cell migration and invasion, blocking cell cycle, and inducing apoptosis.
