People frequently struggle to juggle their work, family, and social life in today’s fast-paced environment, which can leave them exhausted and worn out. The development of technologies for detecting fatigue while driving is an important field of research since driving when fatigued poses concerns to road safety. In order to throw light on the most recent advancements in this field of research, this paper provides an extensive review of fatigue driving detection approaches based on electroencephalography (EEG) data. The process of fatigue driving detection based on EEG signals encompasses signal acquisition, preprocessing, feature extraction, and classification. Each step plays a crucial role in accurately identifying driver fatigue. In this review, we delve into the signal acquisition techniques, including the use of portable EEG devices worn on the scalp that capture brain signals in real-time. Preprocessing techniques, such as artifact removal, filtering, and segmentation, are explored to ensure that the extracted EEG signals are of high quality and suitable for subsequent analysis. A crucial stage in the fatigue driving detection process is feature extraction, which entails taking pertinent data out of the EEG signals and using it to distinguish between tired and non-fatigued states. We give a thorough rundown of several feature extraction techniques, such as topology features, frequency-domain analysis, and time-domain analysis. Techniques for frequency-domain analysis, such wavelet transform and power spectral density, allow the identification of particular frequency bands linked to weariness. Temporal patterns in the EEG signals are captured by time-domain features such autoregressive modeling and statistical moments. Furthermore, topological characteristics like brain area connection and synchronization provide light on how the brain’s functional network alters with weariness. Furthermore, the review includes an analysis of different classifiers used in fatigue driving detection, such as support vector machine (SVM), artificial neural network (ANN), and Bayesian classifier. We discuss the advantages and limitations of each classifier, along with their applications in EEG-based fatigue driving detection. Evaluation metrics and performance assessment are crucial aspects of any detection system. We discuss the commonly used evaluation criteria, including accuracy, sensitivity, specificity, and receiver operating characteristic (ROC) curves. Comparative analyses of existing models are conducted, highlighting their strengths and weaknesses. Additionally, we emphasize the need for a standardized data marking protocol and an increased number of test subjects to enhance the robustness and generalizability of fatigue driving detection models. The review also discusses the challenges and potential solutions in EEG-based fatigue driving detection. These challenges include variability in EEG signals across individuals, environmental factors, and the influence of different driving scenarios. To address these challenges, we propose solutions such as personalized models, multi-modal data fusion, and real-time implementation strategies. In conclusion, this comprehensive review provides an extensive overview of the current state of fatigue driving detection based on EEG signals. It covers various aspects, including signal acquisition, preprocessing, feature extraction, classification, performance evaluation, and challenges. The review aims to serve as a valuable resource for researchers, engineers, and practitioners in the field of driving safety, facilitating further advancements in fatigue detection technologies and ultimately enhancing road safety.

Neuropathic pain(NP) has similar phenotypes but different sequential neuroinflammatory mechanisms in the pathological process. It is of great significance to inhibit the initiation of neuroinflammation, which has become a new direction of NP treatment and drug development in recent years. Mongolian drug Naru-3 is clinically effective in the treatment of trigeminal neuralgia, sciatica, and other NPs in a short time, but its pharmacodynamic characteristics and mechanism of analgesia are still unclear. In this study, a spinal nerve ligation(SNL) model simulating clinical peripheral nerve injury was established and the efficacy and mechanism of Naru-3 in the treatment of NPs was discussed by means of behavioral detection, side effect evaluation, network analysis, and experimental verification. Pharmacodynamic results showed that Naru-3 increased the basic pain sensitivity threshold(mechanical hyperalgesia and thermal radiation hyperalgesia) in the initiation of SNL in animals and relieved spontaneous pain, however, there was no significant effect on the basic pain sensitivity threshold and motor coordination function of normal animals under physiological and pathological conditions. Meanwhile, the results of primary screening of target tissues showed that Naru-3 inhibited the second phase of injury-induced nociceptive response of formalin test in mice and reduced the expression of inflammatory factors in the spinal cord. Network analysis discovered that Naru-3 had synergy in the treatment of NP, and its mechanism was associated with core targets such as matrix metalloproteinase-9(MMP9) and interleukin-1β(IL-1β). The experiment further took the dorsal root ganglion(DRG) and the stage of patho-logical spinal cord as the research objects, focusing on the core targets of inducing microglial neuroinflammation. By means of Western blot, immunofluorescence, agonists, antagonists, behavior, etc., the mechanism of Naru-3 in exerting NP analgesia may be related to the negative regulation of the MMP9/IL-1β signaling pathway-mediated microglia p38/IL-1β inflammatory loop in the activation phase. The relevant research enriches the biological connotation of Naru-3 in the treatment of NP and provides references for clinical rational drug use.

The Baimai Ointment with the effect of relaxing sinew and activating collaterals demonstrates a definite effect on Baimai disease with pain, spasm, stiffness and other symptoms, while the pharmacodynamic characteristics and mechanism of this agent remain unclear. In this study, a rat model of chronic compression of L4 dorsal root ganglion(CCD) was established by lumbar disc herniation, and the efficacy and mechanism of Baimai Ointment in the treatment of CCD were preliminarily explored by behavioral tests, side effect evaluation, network analysis, antagonist and molecular biology verification. The pharmacodynamic experiment indicated that Baimai Ointment significantly improved the pain thresholds(mechanical pain, thermal pain, and cold pain) and gait behavior of CCD model rats without causing tolerance or obvious toxic and side effects. Baimai Ointment inhibited the second-phase nociceptive response of mice in the formalin test, increased the hot plate threshold of normal mice, and down-regulated the expression of inflammatory cytokines in the spinal cord. Network analysis showed that Baimai Ointment had synergistic effect in the treatment of CCD and was related to descending inhibition/facilitation system and neuroinflammation. Furthermore, behavioral tests, Western blot, and immunofluorescence assay revealed that the pain-relieving effect of Baimai Ointment on CCD may be related to the regulation of the interaction between neuroactive ligand and receptors(neuroligands) such as CHRNA7, ADRA2A, and ADRB2, and the down-regulation of the expression of NOS2/pERK/PI3K, the core regulatory element of HIF-1 signaling pathway in spinal microglia. The findings preliminarily reveal the mechanism of relaxing sinew and activating collaterals of Baimai Ointment in the treatment of Baimai disease, providing a reference for the rational drug use and further research of this agent.

Objective:To investigate the expression of long non-coding RNA (Lnc RNA) RP5-919F19 in gastric cancer tissues and its correlation with gastric cancer invasion and metastasis.Methods:Non-tumor gastric mucosa (more than 3cm away from the cancer tissue) and gastric adenocarcinoma tissues were collected from Jan. 2020 to Jan. 2022 in our hospital. TRIzol kit was used to extract total RNA from cells and tissues, and reverse transcription kit was used to reverse transcribed RNA into cDNA. Quantitative real-time PCR kit was used for quantitative analysis. SGC-7901 and AGS human gastric cancer cells were used to construct RP5-919F19 knockdown and overexpression models. CCK-8 assay was used to confirm cell proliferation, and Transwell invasion assay was used to confirm the invasion ability of gastric cancer cells.Results:The expression of RP5-919F19 was detected in 79 cases of gastric cancer tissues and adjacent normal tissues, and it was found that the relative expression of RP5-919F19 in gastric cancer tissues was 1.51±0.05 significantly higher than that of 0.82±0.04 in adjacent normal tissues ( P<0.05) . The levels of RP5-919F19 in patients with different pathological conditions were compared and analyzed. The results showed that there were statistically significant differences in RP5-919F19 expression in patients with different TNM stages, distant metastasis, lymph node metastasis and different depth of invasion ( P<0.05) . There was no significant difference in RP5-919F19 expression among patients with different tumor sizes, ages and genders ( P>0.05) . AGS gastric cancer cells were transfected with RP5-919F19 overexpression plasmid and control plasmid, and the efficiency of RP5-919F19 was detected. The results showed that the expression level of RP5-919F19 in the overexpression group was 1.83±0.14 higher than that of 0.82±0.05 in the control group ( P<0.05) . SGC-7901 gastric cancer cells were transfected with RP5-919F19 knockout vector and control vector, and the efficiency of RP5-919F19 was detected. The results showed that the expression level of RP5-919F19 in the knockout group was 0.42±0.07 lower than that of 0.89±0.08 in the control group ( P<0.05) . CCK-8 was used to detect the proliferation ability of gastric cancer cells. The results showed that the proliferation ability of AGS cells in RP5-919F19 overexpression group was significantly increased compared with that of the control group at 24 and 48h after culture ( P<0.05) . However, the proliferation ability of SGC-7901 cells in RP5-919F19 knockdown group was lower than that in the control group at 24 h and 48 h ( P<0.05) . Transwell invasion assay showed that the invasion and migration abilities of AGS cells in RP5-919F19 overexpression group were higher than those in the control group ( P<0.05) , and the invasion and migration abilities of SGC-7901 cells in RP5-919F19 knockout group were lower than those in the control group ( P<0.05) . Western blot showed that compared with control cells, the expression of MMP-2 and MMP-9COPS7A proteins in down-regulated Lnc RNA RP5-919F19 SGC-7901 cells was decreased. Conclusion:The expression of LncRNA RP5-919F19 is abnormally increased in gastric cancer tissues, and the increased expression of RP5-919F19 can promote the proliferation and metastasis of gastric cancer cells.

Objective: To investigate the application value of computed tomography (CT) examination of lymph node short diameter in evaluating cardia-left gastric lymph node metastasis in thoracic esophageal squamous cell carcinoma (ESCC). Methods: A total of 477 patients with primary thoracic ESCC who underwent surgical treatment in the Affiliated Cancer Hospital of Zhengzhou University from January 2013 to December 2017 were collected. All of them underwent McKeown esophagectomy plus complete two-field or three-field lymph node dissection. Picture archiving and communication system were used to measure the largest cardia-left gastric lymph node short diameter in preoperative CT images. The postoperative pathological diagnosis results of cardia-left gastric lymph node were used as the gold standard. Receiver operating characteristic (ROC) curve was used to evaluate the efficacy of CT lymph node short diameter in detecting the metastasis of cardia-left gastric lymph node in thoracic ESCC, and determine the optimal cut-off value. Results: The median short diameter of the largest cardia-left gastric lymph node was 4.1 mm in 477 patients, and the largest cardia-left gastric lymph node short diameter was less than 3 mm in 155 cases (32.5%). Sixty-eight patients had cardia-left gastric lymph node metastases, of which 38 had paracardial node metastases and 41 had left gastric node metastases. The lymph node ratios of paracardial node and left gastric node were 4.0% (60/1 511) and 3.3% (62/1 887), respectively. ROC curve analysis showed that the area under the curve of CT lymph node short diameter for evaluating cardia-left gastric lymph node metastasis was 0.941 (95% CI: 0.904-0.977; P<0.05). The optimal cut-off value of CT examination of the cardia-left gastric lymph node short diameter was 6 mm, and the corresponding sensitivity, specificity and accuracy were 85.3%, 91.7%, and 90.8%, respectively. Conclusion: CT examination of lymph node short diameter can be a good evaluation of cardia-left gastric lymph node metastasis in thoracic ESCC, and the optimal cut-off value is 6 mm.

The vagina contains at least a billion microbial cells,dominated by lactobacilli.Here we perform metagenomic shotgun sequencing on cervical and fecal samples from a cohort of 516 Chinese women of reproductive age,as well as cervical,fecal,and salivary samples from a second cohort of 632 women.Factors such as pregnancy history,delivery history,cesarean section,and breastfeeding were all more important than menstrual cycle in shaping the microbiome,and such information would be necessary before trying to interpret differences between vagino-cervical micro-biome data.Greater proportion of Bifidobacterium breve was seen with older age at sexual debut.The relative abundance of lactobacilli especially Lactobacillus crispatus was negatively associated with pregnancy history.Potential markers for lack of menstrual regularity,heavy flow,dysmenor-rhea,and contraceptives were also identified.Lactobacilli were rare during breastfeeding or post-menopause.Other features such as mood fluctuations and facial speckles could potentially be predicted from the vagino-cervical microbiome.Gut and salivary microbiomes,plasma vitamins,metals,amino acids,and hormones showed associations with the vagino-cervical microbiome.Our results offer an unprecedented glimpse into the microbiota of the female reproductive tract and call for international collaborations to better understand its long-term health impact other than in the settings of infection or pre-term birth.

A 57-year-old male patient was referred to our department with complaints of his right adrenal gland occupancy and hypertension about 6 months. When admitted to the hospital, the blood pressure was about 160/100 mmHg, and the heart rate was 110 beats/min. He was no obvious obesity, acne, abnormal mood, without weakness of limbs, acral numbness, palpitation and headache. He presented with type 2 diabetes for more than 3 years, with oral administration of metformin enteric coated tablets and subcutaneous injection of insulin glargine to control blood glucose, and satisfied with blood glucose control. Enhanced CT showed that: the right adrenal gland showed a kind of oval isodense, slightly hypodense shadow, the edge was clear, lobular change, the size was about 5.8 cm×5.4 cm, uneven density, there were nodular and strip calcification, round lipid containing area and strip low density area, and the CT value of solid part was about 34 HU. Enhanced scan showed heterogeneous nodular enhancement in the solid part of the right adrenal gland, nodular enhancement could be seen inside. The CT values of solid part in arterial phase, venous phase and delayed phase were 45 HU, 50 HU and 81 HU, respectively. Considering from the right adrenal gland, cortical cancer was more likely. No obvious abnormality was found in his endocrine examination. After adequate preoperative preparation, retroperitoneal laparoscopic adrenalectomy was performed under general anesthesia. During the operation, the 6 cm adrenal tumor was closely related to the inferior vena cava and liver, and after careful separation, the tumor was completely removed and normal adrenal tissue was preserved. The operation lasted 180 min and the blood loss was 100 mL, and the blood pressure was stable during and after the operation. There was no obvious complication. The results of pathological examinations were as follows: the size of the tumor was 7.5 cm×6.0 cm×3.5 cm, soft, with intact capsule and grayish-red cystic in section. Pathological diagnosis: (right adrenal gland) cavernous hemangioma, secondary intravascular thrombosis, old hemorrhagic infarction with calcification and ossification. After 6 months of observation, no obvious complications and tumor recurrence were found. In summary, cavernous hemangioma of adrenal gland is a rare histopathological change. Its essence is a malformed vascular mass. Blood retention is the cause of thrombosis and calcification in malformed vessels. The imaging findings were inhomogeneous enhancement of soft tissue masses, and the adrenal function examination showed no obvious abnormalities. Retroperitoneal laparoscopic surgery is feasible after adequate preoperative preparation. It is difficult to diagnose the disease preoperatively and needs to be confirmed by postoperative pathology.

Salvia miltiorrhiza(Sm) and Salvia castanea f. tomentosa(Sc) hairy roots were used as experimental materials to study the effects of six different carbon sources, galactose, fructose, lactose, glucose, arabinose and sucrose(control), on fresh weight, dry weight, contents and yields of salvianolic acids and tanshinones. The results showed that galactose was most beneficial to the growth of two kinds of hairy roots, while lactose and arabinose were not conducive to their growth. As for Sm hairy roots, fructose significantly promoted the accumulation of salvianolic acid B, and the content increased by 5.801 times and 10.151 times compared with the control group, respectively. Glucose significantly promoted the accumulation of salvianolic acids. The content and yield of rosmarinic acid were 7.674 times and 9.260 times of that of the control group, and the content and yield of salvianolic acid B were 5.532 times and 6.675 times of the control group. For the hairy roots of Sc, galactose significantly increased the content and yield of rosmarinic acid, reaching 7.820 times and 9.944 times of the control group, respectively. Fructose promoted the increase of the content and yield of cryptotanshinone, reaching 9.242 times and 6.609 times of the control group, respectively. The study confirmed the optimal carbon source for the hairy root culture of Sm and Sc, and provided theoretical guidance for large-scale production of Sm drug-derived components and the utilization of Sc.
