ObjectiveTo investigate the effect of Zishen Huoxue Formula （ZSXHF） on molecular-targeted therapy-associated proteinuria in patients with primary liver cancer （PLC）， to assess the efficacy of ZSXHF in the treatment of molecular-targeted therapy-associated proteinuria， and to provide a basis for clinical medication. MethodsA retrospective cohort study was conducted among the PLC patients with molecular-targeted therapy-associated proteinuria who were diagnosed and treated in The Department of Hepatology of Chinese PLA General Hospital， from January 1， 2022 to July 1， 2025. With ZSXHF treatment as the exposure factor， the patients with a cumulative treatment duration of ≥9 weeks were enrolled as traditional Chinese medicine （TCM） group， while those without TCM treatment were enrolled as control group. Propensity score matching was performed for the two groups at a ratio of 1∶1 based on sex， age， 24-hour urinary protein， blood urea nitrogen， and serum creatinine. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test was used for comparison of categorical data between groups. Univariate and multivariate Logistic regression analyses were used to investigate the influencing factors for promoting the improvement of targeted-therapy-associated proteinuria. ResultsA total of 137 PLC patients with targeted-therapy-associated proteinuria were enrolled， with 34 patients in the TCM group and 103 in the control group. After follow-up for 6 months， the TCM group had a significant improvement in urinary protein grade compared with the control group （χ²=9.261， P=0.016）. There were 25 patients in each group after propensity score matching， and after follow-up for 6 months， there were significant differences between the two groups in urinary protein grade （χ²=15.689， P<0.001） and 24-hour urinary protein （Z=-3.075， P=0.002）. After cumulative treatment with ZSXHF for ≥9 weeks， the TCM group had a significantly greater change in 24-hour urinary protein from baseline compared with the control group （t=-2.514， P=0.016）， while there were no significant differences in the changes in liver and renal function after ZSXHF intervention between the two groups （all P>0.05）. The multivariate Logistic regression analysis showed that ZSXHF treatment （odds ratio=2.901， 95% confidence interval： 1.135 — 7.417， P=0.026） was an independent influencing factor for improvement in molecular-targeted therapy-associated proteinuria. ConclusionZSHXF can effectively alleviate molecular-targeted therapy-associated proteinuria in PLC patients with a favorable safety profile， which provides a new reference for TCM prevention and treatment of molecular-targeted therapy-associated adverse reactions in PLC patients.

BACKGROUND:Traumatic brain injury is a condition in which the normal function of the brain is disrupted by a bump or impact to the head.It is necessary to find effective treatments and objective targets that can help doctors diagnose the injury status and restore the brain function of patients. OBJECTIVE:To explore the effect of electroacupuncture combined with low-frequency transcranial ultrasound stimulation on the electroencephalographic signals of rats with traumatic brain injury. METHODS:Forty 6-week-old SPF male Sprague-Dawley rats were randomly divided into five groups:sham group,model group,electroacupuncture group,low-frequency transcranial ultrasound stimulation group and combined group(electroacupuncture+low-frequency transcranial ultrasound stimulation),with eight rats in each group.Feeney weight-drop method was used to establish the animal model of traumatic brain injury.In the sham group,the bone window was only opened without impact.Interventions were started at 1 day after modeling.Electroacupuncture in the electroacupuncture group,low-frequency transcranial ultrasound stimulation in the low-frequency transcranial ultrasound stimulation group,and electroacupuncture+low-frequency transcranial ultrasound stimulation in the combined group were performed for days in total.The modified neurological severity scale score for assessing rats'neurological deficits was performed at 8 hours after modeling.The percentage of spontaneous alternation behavior in the Y-maze was measured at 7 days after modeling.Then,the electroencephalographic signals were collected and electroencephalographic data of α,β,θ,and δ waves were extracted by fast Fourier transform,and the value of oscillation amplitude and energy ratio were calculated in α,β,θ,and δ waves,as well as the Lempel-Ziv complexity and sample entropy. RESULTS AND CONCLUSION:Compared with the sham group,the modified neurological severity scale scores in the model group,electroacupuncture group,low-frequency transcranial ultrasound stimulation group and combined group were significantly increased at 8 hours after modeling(P<0.05).Compared with the sham group,the value of oscillation amplitude in δ wave and the value of δ energy ratio were significantly increased in the model group at 7 days after modeling,meanwhile the percentage of spontaneous alternation behavior in Y-maze,and the value of α/β energy ratio,Lempel-Ziv complexity,and sample entropy were significantly decreased(P<0.05).Compared with the model group,the value of oscillation amplitude in α and δ waves was significantly decreased in the combined group(P<0.05),while the value of α/β energy ratio was significantly increased(P<0.05)and the value of δ energy ratio was significantly decreased(P<0.05)in the electroacupuncture group,low-frequency transcranial ultrasound stimulation group and combined group.Compared with the electroacupuncture group and low-frequency transcranial ultrasound stimulation group,the value of δ energy ratio was significantly decreased in the combined group(P<0.05),while the percentage of spontaneous alternation behavior,the value of α/β energy ratio,the Lempel-Ziv complexity,and the sample entropy were significantly increased(P<0.05).To conclude,abnormal electroencephalographic signals can appear in rats with traumatic brain injury,while the electroacupuncture combined with low-frequency transcranial ultrasound stimulation can alleviate the abnormal electroencephalographic signals in rats,which suggests the electroencephalographic frequency domain value and nonlinear features can be used to assess the severity of traumatic brain injury.

Objective:To investigate the additional value of 99Tc m-hydrazinonicotinamide (HYNIC)-Tyr3-octreotide (TOC) SPECT/CT imaging in the diagnosis and treatment of gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Methods:A total of 54 patients (28 males and 26 females, age: (52.6±11.7) years) who underwent enhanced CT (MR) and 99Tc m-HYNIC-TOC SPECT/CT in People′s Hospital of Zhengzhou University between December 2017 and June 2023 were analyzed retrospectively. Surgical pathology or biopsy was the gold standard of patients′ diagnosis (primary tumors), and comprehensive evaluation based on pathology, imaging and follow-up results was used as the diagnostic criteria of lesions. McNemar χ2 test was used to compare the diagnostic efficacy of different imaging methods. Results:Pathological results showed that 43 of the 54 patients were with GEP-NETs and 11 were with non-neuroendocrine tumors (NETs). The sensitivities of enhanced CT and enhanced MR in the diagnosis of patients with GEP-NETs were 65.1%(28/43) and 60.0%(15/25) respectively, which increased to 93.0%(40/43) and 92.0%(23/25) with the addition of 99Tc m-HYNIC-TOC imaging ( χ2 values: 8.64, 4.90, P values: 0.002, 0.021). There were 22 and 15 patients showing atypical enhancement on enhanced CT and enhanced MR respectively. The sensitivities of these two methods for GEP-NETs in patients with atypical enhancement were 54.5%(12/22) and 8/15 respectively, which increased to 95.5%(21/22) and 14/15 with the addition of 99Tc m-HYNIC-TOC imaging ( χ2 values: 5.82, 4.17, P values: 0.012, 0.031). Compared with enhanced CT, the detection rates of liver and bone metastatic lesions were improved significantly from 90.8%(158/174) and 55.2%(32/58) to 96.6%(168/174) and 87.9%(51/58) with the addition of 99Tc m-HYNIC-TOC imaging ( χ2 values: 5.79, 9.82, P values: 0.013, 0.001). Compared with enhanced MR, the detection rate of bone metastases was improved significantly from 56.0%(14/25) to 88.0%(22/25) with the addition of 99Tc m-HYNIC-TOC imaging ( χ2=4.08, P=0.039). After 99Tc m-HYNIC-TOC imaging, stages were changed in 7.0%(3/43) of patients and a greater number or extent of metastases were detected in 11.6%(5/43) of patients. 99Tc m-HYNIC-TOC imaging detected additional recurrent or metastatic lesions in 40.0%(8/20) of patients during follow-up compared to enhanced CT. Conclusion:99Tc m-HYNIC-TOC imaging can provide an added value for diagnosing GEP-NETs with atypically enhanced CT(MR), and in the detection of liver metastasis and early bone metastasis, thus helping the optimization of clinical treatment strategies.

BACKGROUND: Retinal ganglion cell (RGC) death caused by acute ocular hypertension is an important characteristic of acute glaucoma. Receptor-interacting protein kinase 3 (RIPK3) that mediates necroptosis is a potential therapeutic target for RGC death. However, the current understanding of the targeting agents and mechanisms of RIPK3 in the treatment of glaucoma remains limited. Notably, artificial intelligence (AI) technologies have significantly advanced drug discovery. This study aimed to discover RIPK3 inhibitor with AI assistance. METHODS: An acute ocular hypertension model was used to simulate pathological ocular hypertension in vivo . We employed a series of AI methods, including large language and graph neural network models, to identify the target compounds of RIPK3. Subsequently, these target candidates were validated using molecular simulations (molecular docking, absorption, distribution, metabolism, excretion, and toxicity [ADMET] prediction, and molecular dynamics simulations) and biological experiments (Western blotting and fluorescence staining) in vitro and in vivo . RESULTS: AI-driven drug screening techniques have the potential to greatly accelerate drug development. A compound called HG9-91-01, identified using AI methods, exerted neuroprotective effects in acute glaucoma. Our research indicates that all five candidates recommended by AI were able to protect the morphological integrity of RGC cells when exposed to hypoxia and glucose deficiency, and HG9-91-01 showed a higher cell survival rate compared to the other candidates. Furthermore, HG9-91-01 was found to protect the retinal structure and reduce the loss of retinal layers in an acute glaucoma model. It was also observed that the neuroprotective effects of HG9-91-01 were highly correlated with the inhibition of PANoptosis (apoptosis, pyroptosis, and necroptosis). Finally, we found that HG9-91-01 can regulate key proteins related to PANoptosis, indicating that this compound exerts neuroprotective effects in the retina by inhibiting the expression of proteins related to apoptosis, pyroptosis, and necroptosis. CONCLUSION AI-enabled drug discovery revealed that HG9-91-01 could serve as a potential treatment for acute glaucoma.

Objective:To investigate the value of 99Tc m-hydrazinonicotinamide (HYNIC)-prostate specific membrane antigen(PSMA) SPECT/CT imaging in biochemical recurrence of prostate cancer (PCa). Methods:From January 2018 to March 2023, 112 patients with biochemical recurrence of PCa (age (72.6±6.1) years) who underwent 99Tc m-HYNIC-PSMA SPECT/CT imaging in Henan Provincial People′s Hospital were retrospectively analyzed. According to the level of prostate specific antigen (PSA), patients were divided into 0.2 μg/L2 μg/L group. According to the Gleason score, patients were divided into Gleason score≥8 group and Gleason score <8 group. The detection rate between groups was analyzed by χ2 test, and the difference of the PSA level between groups was compared by Mann-Whitney U test. Results:PSMA imaging was positive in 77 cases and negative in 35 cases, with the detection rate of 68.8%(77/112). The detection rates of local recurrence, lymph node metastasis, bone metastasis and lung metastasis were 8.9%(10/112), 43.8%(49/112), 28.6%(32/112) and 0.9%(1/112), respectively. The detection rates of 0.2 μg/L2 μg/L groups were 44.7%(21/47), 8/12 and 90.6%(48/53), respectively ( χ2=24.44, P<0.001). The detection rates of Gleason score ≥8 group and <8 group were 76.4%(55/72) and 55.0%(22/40) ( χ2=5.47, P=0.032); the PSA level between the two groups was statistically different (3.11(0.75, 5.91) and 0.84(0.44, 2.92) μg/L; z=-2.99, P=0.003). Of the patients with PSMA positive imaging, 84.4%(65/77) changed their treatment regimen and 15.6%(12/77) continued to observe or maintain the original treatment plan. Of the patients with PSMA negative imaging, 40.0%(14/35) changed the treatment plan, 51.4%(18/35) continued to observe or maintain the original treatment plan, and 8.6%(3/35) discontinued the original treatment because no tumor metastasis was found. Conclusion:99Tc m-HYNIC-PSMA SPECT/CT imaging can provide reference for the lesion detection, treatment decision-making and follow-up observation of biochemical recurrence of PCa.

BACKGROUND:There is less report about mitigating sustained bone grinding injuries during craniotomy based on a model of traumatic brain injury established using the modified Feeney's free-fall method. OBJECTIVE:To modify a modified traumatic brain injury model by altering the opening of the skull window. METHODS:Thirty-six Sprague-Dawley rats were equally randomized into sham group,model group and modified model group.The modified procedure of opening the bone window was used in the modified model group.Six to eight small holes of 0.3-0.5 mm in diameter were punched at the edge of the impact area and the drill was immediately withdrawn without touching the cortex.In the modified model group,the skull window was opened by using the modified method,while the skull window in the model group was opened using the conventional method.The modified model group and model group were established using the Feeney's free-fall method.In the sham group,only the skull window was opened without impact.The modified neurological severity scoring was performed at 1 day after modeling.T2 weighted imaging was performed and T2 values were measured at 1 and 7 days after modeling.Hematoxylin-eosin staining of the brain section was made for histopathological observation at 7 days after modeling.The level of blood viscosity,interleukin-6,interleukin-1β,and tumor necrosis factor-α were determined at 7 days after modeling. RESULTS AND CONCLUSION:Compared with the sham group,the modified neurological severity scores in the model group and modified model group were significantly increased at 1 day after modeling(P＜0.000 1).Meanwhile,the modified neurological severity scores in the modified model group were lower than those in the model group(P＜0.000 1).Compared with the sham group,the T2 values were significantly increased in the model group and modified model group at 1 and 7 days after modeling(P＜0.05),while the T2 values in the modified model group were lower than those in the model group(P＜0.05).Compared with the sham group,the level of blood viscosity,interleukin-6,interleukin-1β and tumor necrosis factor-α were increased in the model group and modified model group at 7 days after modeling(P＜0.05),while the level of interleukin-6 in the modified model group was lower than that in the model group(P＜0.05).To conclude,establishing a modified traumatic brain injury model based on the Feeney's free-fall method provides better controls of injury factors during cranial opening.

Traditional Chinese Medicine (TCM) shows unique advantages in the field of adjuvant treatment of gastric cancer. The main mechanism of TCM in improving gastric cancer includes regulating cell proliferation and apoptosis, reversing cell resistance, reducing the ability of invasion and metastasis and epithelial-mesenchymal transformation, regulating immune function, inhibiting neovascularization, regulating autophagy exosome, and ferroptosis.

Patients in intensive care unit were more critically ill, and often accompanied by dottiness and restless. In order to avoid the adverse events and self-injury, body constraints were often used on the patients. Therefore, this paper would discuss the ethics of body constraints and give the suggestions. According to the literature review and the analysis of the clinical nursing experience of relevant ethical principles, data was collected. The principle of informed consent, respect, and harmless was hard to decide on the issue of body constraints for patients in ICU. Nurses might pay attention to the application of ethical principles, and strengthen the humanistic care. On the issue of body constraints for ICU patients, nurses might pay special attention to the application of possible ethics principles in nursing process and reduce the application of the body constraints, and promote the physical and mental comfort of patients. It reflected the progress of the humanistic solicitude in the current clinical nursing and important value.
