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.

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.

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.

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.

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.
