Aim To explore the effects of Lycium berry seed oil on Nrf2/ARE pathway and oxidative damage in testis of subacute aging rats. Methods Fifty out of 60 male SD rats, aged 8 weeks, were subcutaneously injected with 125 mg • kg"D-galactosidase in the neck for 8 weeks to establish a subacute senescent rat model. The presence of senescent cells was observed using P-galactosidase ((3-gal), while testicular morphology was examined using HE staining. Serum levels of testosterone (testosterone, T), follicle-stimulating hormone ( follicle stimulating hormone, FSH ) , luteinizing hormone ( luteinizing hormone, LH ) , superoxide dis-mutase ( superoxide dismutase, SOD ) , glutathione ( glutathione, GSH) and malondialdehyde ( malondial-dehyde, MDA) were measured through ELISA, and the expressions of factors related to aging, oxidative damage, and the Nrf2/ARE pathway were assessed via immunohistochemical analysis and Western blotting. Results After successfully identifying the model, the morphology of the testis was improved and the intervention of Lycium seed oil led to a down-regulation in the expression of [3-gal and -yH2AX. The serum levels of SOD, GSH, T, and FSH increased while MDA and LH decreased (P 0. 05) . Additionally, there was an up-regulated expression of Nrf2, GCLC, NQOl, and SOD2 proteins in testicular tissue ( P 0. 05 ) and nuclear expression of Nrf2 in sertoli cells. Conclusion Lycium barbarum seed oil may reduce oxidative damage in testes of subacute senescent rats by activating the Nrf2/ARE signaling pathway.

Hydroxysafflor Yellow A Promotes HaCaT Cell Proliferation and Migration by Regulating HBEGF/EGFR and PI3K/AKT Pathways and Circ_0084443 / 中国结合医学杂志

OBJECTIVE@#To investigate the effect and possible mechanism of hydroxysafflor yellow A (HSYA) on human immortalized keratinocyte cell proliferation and migration.@*METHODS@#HaCaT cells were treated with HSYA. Cell proliferation was detected by the cell counting kit-8 assay, and cell migration was measured using wound healing assay and Transwell migration assay. The mRNA and protein expression levels of heparin-binding epidermal growth factor (EGF)-like growth factor (HBEGF), EGF receptor (EGFR), phosphatidylinositol 3-kinase (PI3K), protein kinase B (AKT), mammalian target of rapamycin (mTOR), and hypoxia-inducible factor-1α (HIF-1α) were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot, respectively. Circ_0084443-overexpressing HaCaT cells and empty plasmid HaCaT cells were constructed using the lentiviral stable transfection and treated with HSYA. The expression of circ_0084443 was detected by qRT-PCR.@*RESULTS@#HSYA (800 µmol/L) significantly promoted HaCaT cell proliferation and migration (P<0.05 or P<0.01). It also increased the mRNA and protein expression levels of HBEGF, EGFR, PI3K, AKT, mTOR and HIF-1α, and increased the phosphorylation levels of PI3K and AKT (P<0.05 or P<0.01). Furthermore, HSYA promoted HaCaT cell proliferation and migration via the HBEGF/EGFR and PI3K/AKT/mTOR signaling pathways (P<0.01). Circ_0084443 attenuated the mRNA expression levels of HBEGF, EGFR, PI3K, AKT, mTOR and HIF-1α (P<0.05). HSYA inhibited the circ_0084443 expression, further antagonized the inhibition of circ_0084443 on HBEGF, EGFR, PI3K, AKT, mTOR and HIF-1α, and promoted the proliferation of circ_0084443-overexpressing HaCaT cells (P<0.05 or P<0.01). However, HSYA could not influence the inhibitory effect of circ_0084443 on HaCaT cell migration (P>0.05).@*CONCLUSION@#HSYA played an accelerative role in HaCaT cell proliferation and migration, which may be attributable to activating HBEGF/EGFR and PI3K/AKT signaling pathways, and had a particular inhibitory effect on the keratinocyte negative regulator circ_0084443.

Application and Challenges of EEG Signals in Fatigue Driving Detection / 生物化学与生物物理进展

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.

The total effective rate was 92.5% (37/40) in the governor vessel moxibustion group, which was higher than 75.6% (31/41) in the western medication group and 80.5% (33/41) in the placebo moxibustion group (P<0.05).@*CONCLUSION@#Governor vessel moxibustion combined with fluoxetine hydrochloride capsule can improve the degree of depression and relieve the clinical symptoms in mild to moderate depression patients with kidney-yang deficiency, the efficacy is superior to simple fluoxetine hydrochloride capsule, and can reduce the fluoxetine hydrochloride capsule-induced adverse effect to a certain extent.

Reclassification of flat type sudden deafness / 中华耳鼻咽喉头颈外科杂志

Objective: To reclassify the flat type sudden deafness according to the types of audiogram shape, and to explore the correlation between different pattern of hearing loss and prognosis. Methods: All of 1 024 patients with unilateral sudden deafness (492 males and 532 females, aged from 19 to 65 years, with an average age of 41.2 years old) admitted to 33 hospitals nationwide from August 2007 to October 2011 were divided into four types according to Chinese Guideline of Sudden Deafness(2015): low-frequency, high-frequency, flat and total deafness. Then, 402 patients with flat type sudden deafness were further divided into ascending type, descending type and consistent type according to the audiogram shapes. First, we compared the clinical characteristics and prognosis among these three subtypes of flat deafness, then compared the clinical characteristics and prognosis between ascending flat deafness and low-frequency deafness, descending flat deafness and high-frequency deafness, consistent flat deafness and total deafness, explored the factors related to the prognosis of flat deafness. SPSS 21.0 software, ANOVA, χ2 test, t-test and Logistic regression were used to analyze the data. Results: The cure rates of flat ascending, flat descending and flat consistent sudden deafness groups were 70.7%, 17.1% and 34.0% respectively, with a statistically significant difference (χ2=33.984, P<0.001); However, there was no significant difference in age, sex and affected side (all P>0.05). The independent related factors for the recovery of flat type sudden deafness were as follows: whether there was dizziness [OR=0.459; 95% confidence interval (CI): 0.271-0.777], the type of audiogram shape (OR=0.721; 95%CI: 0.530-0.981), and days from onset to therapy (OR=0.903, 95%CI: 0.835-0.978), all of which had P values<0.05. There was no significant difference in the cure rates between ascending flat sudden deafness and low-frequency descending sudden deafness, descending flat sudden deafness and high-frequency descending sudden deafness (all P>0.05). The pure tone average(PTA) of flat consistent sudden deafness and total deafness were (69.1±18.9) and (101.7±17.7) dB HL, respectively, with a statistically significant difference (t=20.890, P<0.001), and the cure rates were 34.0% and 14.5%, respectively, with a statistically significant difference (χ2=29.012, P<0.001). Conclusion: According to the audiogram shape, the flat type sudden deafness can be further divided into ascending flat sudden deafness, descending flat sudden deafness and consistent flat sudden deafness, which can more effectively evaluate the prognosis. The cure rate of ascending flat sudden deafness is similar to that of low-frequency sudden deafness, and the prognosis is well; The cure rate of descending flat sudden deafness is similar to that of high-frequency descending sudden deafness, and the prognosis is poor. The cure rate of consistent flat sudden deafness is higher than that of total deafness. PTA plays an important role in the prognosis of consistent flat sudden deafness and total deafness. Total deafness can be regarded as a single type of sudden deafness.

Discovery of biomarkers related to abnormal lipid metabolism in liver and serum and intervention mechanism of ginsenoside Rb_1 in hyperlipidemia rats based on non-targeted metabolomics / 中国中药杂志

Through the non-targeted metabolomics study of endogenous substances in the liver and serum of hyperlipidemia rats, the biomarkers related to abnormal lipid metabolism in hyperlipidemia rats were found, and the target of ginsenoside Rb_1 in improving hyperlipidemia was explored and its mechanism was elucidated. The content of serum biochemical indexes of rats in each group was detected by the automatic biochemical analyzer. The metabolite profiles of liver tissues and serum of rats were analyzed by HPLC-MS. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to compare and analyze the metabolic data in the normal group, the hyperlipidemia group, and the ginsenoside Rb_1 group, and screen potential biomar-kers. The related metabolic pathways were further constructed by KEGG database analysis. The results showed that hyperlipemia induced dyslipidemia in rats, which was alleviated by ginsenoside Rb_1. The non-targeted metabolomics results showed that there were 297 differential metabolites in the liver tissues of hyperlipidemia rats, 294 differential metabolites in the serum samples, and 560 diffe-rential metabolites in the hyperlipidemia rats treated by ginsenoside Rb_1. Perillic acid and N-ornithyl-L-taurine were common metabolites in the liver and serum samples, which could be used as potential biomarkers for ginsenoside Rb_1 in the improvement of hyperlipidemia. As revealed by pathway enrichment in the liver and serum, ginsenoside Rb_1 could participate in the metabolic pathway of choline in both the liver and serum. In addition, ginsenoside Rb_1 also participated in the ABC transporter, alanine, aspartic acid, and glutamate metabolism, protein digestion and absorption, β-alanine metabolism, taurine and hypotaurine metabolism, caffeine metabolism, valine, leucine, and isoleucine biosynthesis, arachidonic acid metabolism, and methionine and cysteine metabolism to improve dyslipidemia in rats.

Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly (version 2023) / 中华创伤杂志

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

Objective:To explore the value of quantitative parameters of enhanced MRI in predicting the establishment of inferior vena cava collateral circulation in patients with renal cell carcinoma and inferior vena cava tumor thrombus.Methods:Sixty-seven patients with renal cell carcinoma and inferior vena cava tumor thrombus who underwent radical resection and inferior vena cava venography in First Medical Center, PLA General Hospital from May 2006 to January 2021 were included retrospectively. According to the results of inferior vena cava venography, the patients were divided into two groups: the well-established collateral circulation group ( n=41) and the poor-established collateral circulation group ( n=26). Quantitative parameters were measured on preoperative enhanced MRI images, including tumor size, the maximum diameter of bilateral lumbar veins, the length of tumor thrombus, and the long and short diameters of tumor thrombus. Student′s t test or Mann-Whitney U test was used for comparison between the two groups. The independent risk factors related to the establishment of collateral circulation were obtained by binary logistic regression analysis and the model was established. The receiver operating characteristic curve was employed to evaluate MRI quantitative parameters and the logistic model, and the area under the curve (AUC) was compared by the DeLong test. Results:Between the well-established collateral circulation group and the poor-established collateral circulation group, the maximum diameter of the right lumbar vein, the maximum diameter of the left lumbar vein, the length of the tumor thrombus, the long diameter of the tumor thrombus, and the short diameter of the tumor thrombus were different significantly ( P<0.05). There was no significant difference in the tumor size between the two groups ( t=0.30, P=0.766). The AUC of the maximum diameters of the right lumbar veins and left lumbar veins, length of tumor thrombus, long and short diameters of tumor thrombus in predicting the collateral circulation were 0.917 (95%CI 0.824-0.971), 0.869 (95%CI 0.764-0.939), 0.756 (95%CI 0.636-0.853), 0.886 (95%CI 0.785-0.951), and 0.906 (95%CI 0.809-0.963). The AUC of the maximum diameter of the right lumbar vein and the short diameter of the tumor thrombus were larger than those of the length of the tumor thrombus, and the differences were statistically significant ( Z=2.25, 2.04, P=0.025, 0.041), but the AUC between other parameters had no significant difference ( P>0.05). The maximum diameter of the right lumbar vein (OR 24.210, 95%CI 2.845-205.998), the maximum diameter of the left lumbar vein (OR 20.973, 95%CI 2.359-186.490), and the length of the tumor thrombus (OR 23.006, 95%CI 2.952-179.309) were independent risk factors for predicting the establishment of inferior vena cava collateral circulation. The AUC of logistic model was 0.969 (95%CI 0.931-1.000). Conclusion:Quantitative parameters of tumor thrombus and lumbar vein based on enhanced MRI have a good ability in predicting the establishment of inferior vena cava collateral circulation in patients with renal cell carcinoma and inferior vena cava tumor thrombus. The maximum diameter of bilateral lumbar veins and the length of the tumor thrombus were independent risk factors for inferior vena cava collateral circulation.

The tests of hepatitis B virus, hepatitis C virus, cytomegalovirus and EB virus were all negative in 35 children, and the autoimmune hepatitis antibodies were also negative. A total of 34 different ATP7B gene mutations were detected; the most frequent mutation was c.2333G>T (P.R778L) at exon 8, followed by c.2621C>T(p.A874V)at exon 11 and c.2621C>T(p.A874V)at exon 13. There was no significant difference in clinical phenotype between patients with nonsense mutation, frameshift mutation or splicing mutation and those with only missense mutations( Z=-1.00, t=-0.16, Z=-1.14, Z=-1.03,all P>0.05). Conclusions:The onset of WD in children is obscure, and clinicians should consider this disease in patients presenting with elevated transaminase. Ceruloplasmin and urine copper should be tested timely, the early diagnosis and treatment can improve the prognosis. And there is no significant correlation between genotype and clinical phenotype.

Clinical characteristics among 67 cases of botulism in Xinjiang Uygur Autonomous Region, China / 中华神经科杂志

Objective:To investigate epidemiological and clinical characteristics of botulism, and the adverse events among those received botulinum antitoxin treatment.Methods:Patients with discharge diagnosis as botulism in the Second Affiliated Hospital of Xinjiang Medical University were enrolled between 2017 and 2021. The epidemiological and clinical characteristics were evaluated. Infection and mechanical ventilation as in-hospital outcomes according to baseline characteristics were analyzed. Patients with and without the interested outcomes were compared. The adverse outcomes among those received botulinum antitoxin treatment were investigated. Those with and without the adverse outcomes were also compared.Results:Sixty-seven cases of botulism were enrolled, and most cases got sick between January and March (32/67, 47.8%); among them 62 cases were Han ethnicity (92.5%); prevalence was highest in Aksu region (15/67, 22.4%); commonly seen symptoms and signs included fatigue (58/67, 86.6%), dysphagia (48/67, 71.6%), dizziness (42/67, 62.7%), ptosis (42/67, 62.7%), blurred vision (41/67, 61.2%), and limb weakness (35/67, 52.2%). Compared with patients without in-hospital infection ( n=52), patients with in-hospital infection ( n=15) were more likely to have severe botulism (0/52 vs 5/15, χ 2=19.79, P<0.001), diplopia (16/52, 30.8% vs 11/15, χ 2=8.77, P=0.003), dysarthria (17/52, 32.7% vs 11/15, χ 2=7.91, P=0.005), consciousness disorder (1/52, 1.9% vs 4/15, χ 2=10.32, P=0.008). Compared with patients without mechanical ventilation (62/67, 92.5%), patients with mechanical ventilation (5/67, 7.5%) were more likely to have severe botulism (5/5 vs 0/62, χ 2=41.17, P<0.001), and consciousness disorder (4/5 vs 1/62, 1.6%, χ 2=29.58, P<0.001). Among 67 cases of botulism, 19 cases (28.4%) had adverse events after receiving antitoxin treatment, with an average of 6.5 days from the antitoxin treatment beginning to the adverse event onset; among the 19 cases, 18 cases (94.7%) had rash. Age, sex, and severity did not differ between the groups with ( n=19) and without adverse events ( n=48) after receiving antitoxin treatment. Conclusions:Fatigue, dysphagia, dizziness, ptosis were the most frequent symptoms and signs in the botulism in Xinjiang Uygur Autonomous Region, China. Infection was a commonly seen complication of botulism, and proactive prevention and close monitoring were needed. Adverse events after receiving antitoxin were prevalent, and might not be associated with age, sex, and severity of botulism.

Diagnostic and therapeutic value of endoscopy and mucosal histology for digestive tract diseases in infants / 中华消化内镜杂志

Objectives:To investigate the clinical value of endoscopy and mucosal histology for digestive tract diseases in infants.Methods:Clinical data of 357 infants who underwent 422 gastrointestinal endoscopies from January 2010 to December 2021 were collected. The indications, endoscopic manifestations, histological features of mucosa and diagnosis were analyzed.Results:A total of 159 gastroscopies and 263 colonoscopies were performed. Diarrhea (185 cases), bloody stool (178 cases) and vomiting (46 cases) were common symptoms. Endoscopy showed manifestations including non-specific inflammatory changes (265 cases), ulcer-like changes (72 cases), and normal mucusa (48 cases). A total of 373 biopsies were performed, including 260 cases of abnormal mucosal histology, 109 cases of normal mucosal histology, and 4 cases of too small biopsy specimens for analysis. Diagnoses were 208 cases of anaphylactic disease, 45 cases of inflammatory bowel disease, 15 cases of variation of structure, 10 cases of intestinal lymphangiectasis, 2 cases of autoimmune enteropathy, and 1 case of celiac disease. There was only 1 colonic perforation complicating endoscopy in terms of endoscopic complication.Conclusions:It is safe and effective to perform endoscopy standardly for digestive tract diseases in infants. Endoscopy with biopsies is a greatly informative test for diagnosis in infants.

Glomuvenous malformation: a clinicopathological analysis of 31 cases / 中华病理学杂志

Objective: To investigate the clinicopathological features of glomuvenous malformation (GVM). Methods: Thirty-one cases of GVM diagnosed at the Henan Provincial People's Hospital from January 2011 to December 2021 were collected. Their clinical and pathological features were analyzed. The expression of relevant markers was examined using immunohistochemistry. The patients were also followed up. Results: There were 16 males and 15 females in this study, with an average age of 11 years (range, 1-52 years). The locations of the disease included 13 cases in the limbs (8 cases in the upper limbs, 5 cases in the lower limbs), 9 cases in the trunks, and 9 cases in the foot (toes or subungual area). Twenty-seven of the cases were solitary and 4 were multifocal. The lesions were characterized by blue-purple papules or plaques on the skin surface, which grew slowly. The lumps became larger and appeared to be conspicuous. Microscopically, GVM mainly involved the dermis and subcutaneous tissue, with an overall ill-defined border. There were scattered or clustered irregular dilated vein-like lumens, with thin walls and various sizes. A single or multiple layers of relatively uniform cubic/glomus cells were present at the abnormal wall, with scattered small nests of the glomus cells. The endothelial cells in the wall of abnormal lumen were flat or absent. Immunohistochemistry showed that glomus cells strongly expressed SMA, h-caldesmon, and collagen IV. Malformed vascular endothelial cells expressed CD31, CD34 and ERG. No postoperative recurrence was found in the 12 cases. Conclusions: GVM is an uncommon type of simple venous malformation in the superficial soft tissue and different from the classical glomus tumor. Morphologically, one or more layers of glomus cells grow around the dilated venous malformation-like lumen, which can be combined with common venous malformations.

Clinical Characteristics of Celiac Disease in Adult Patients With Different Genders / 胃肠病学

Background:Celiac disease has a wide range of clinical manifestations and a higher prevalence in women.Aims:To evaluate the differences in clinical characteristics in adult celiac disease patients with different genders.Methods:Adult patients(age≥18 years)diagnosed as celiac disease from July 2017 to July 2022 at the People's Hospital of Xinjiang Uygur Autonomous Region were included consecutively in the retrospective study.Comparisons of baseline demography,and clinical and pathological features between different genders were performed.Results:A total of 73 adult celiac disease patients were enrolled,19 were males and 54 were females,with the ratio of male to female being 1:2.84.The peak age group of onset was 30-59 years old,with an average age of(50.2±13.6)years for men and(43.5±13.2)years for women at diagnosis.There was no significant difference in the distribution of different age groups between men and women(P>0.05),but the proportion of women in 18-49 years age group and≥50 years age group were both higher than that of men with statistical significance(P<0.05).The most common gastrointestinal symptoms were chronic diarrhea(56.2%)and abdominal pain(56.2%),and anemia was the most common extraintestinal manifestation(50.7%),which was existed in 36.8%of males and 55.6%of females.Abdominal pain and nausea/vomiting were more common in females(all P<0.05),whereas no statistically significant differences were found between male and female groups in other gastrointestinal and extraintestinal manifestations,such as chronic diarrhea,flatulence,decreased appetite,weight loss,chronic fatigue,anemia,hypoproteinemia,osteoporosis/bone loss,etc(all P>0.05).The pathological grading of small intestinal biopsy was Marsh Ⅱin 6 cases,and Marsh Ⅲa,Ⅲb and Ⅲc in 14,23,and 30 cases,respectively.No statistically significant difference was observed in pathological grading between patients with different genders(P>0.05).Conclusions:There is a marked female predominance in adult celiac disease in Xinjiang Uygur Autonomous Region,and women were diagnosed at a younger age.Chronic diarrhea,abdominal pain and anemia present as the most common gastrointestinal and extraintestinal manifes-tations.Abdominal pain and nausea/vomiting are more common in women than in men.
