ABSTRACT

ObjectiveTo clarify the evolutionary laws of syndromes and syndrome elements at different stages during the malignant transformation of chronic hepatitis B (CHB). MethodsA total of 671 patients with hepatitis B virus infection, who were admitted to the outpatient and inpatient departments of Dongzhimen Hospital of Beijing University of Chinese Medicine and The Fifth Medical Center of Chinese PLA General Hospital from July 1st, 2020 to June 30th, 2021, were included, involving 120 cases of CHB, 340 cases of hepatitis B liver cirrhosis (HBLC), 64 cases of precancerous lesions with hepatitis B liver cirrhosis (PLHC), and 147 cases of hepatitis B liver cirrhosis with hepatocellular carcinoma (HCC). A Survey form of traditional Chinese medicine syndrome during malignant transformation of chronic hepatitis B was designed, and the general information, auxiliary examination and the four examinations results were collected. Factor analysis and K-means clustering were used to determine and statistically analyze the syndrome and syndrome elements. ResultsFive traditional Chinese medicine (TCM) syndrome types were identified in CHB patients, while there were six TCM syndrome types in HBLC, PLHC and HCC stages. Among CHB patients, the main syndromes were liver constraint and spleen deficiency (53.33%) and liver-gallbladder damp-heat (21.67%), and the dominant syndrome elements were qi stagnation (27.60%), heat (17.71%) and qi deficiency (17.71%). In the HBLC stage, the syndromes were mainly blood stasis obstructing the collaterals (23.83%) and liver constraint and spleen deficiency (22.35%), with dominant syndrome elements being blood stasis (19.25%), dampness (17.46%), and qi deficiency (15.01%). For the PLHC stage, the primary syndrome types were blood stasis obstructing the collaterals (29.68%) and liver-kidney yin deficiency (20.31%), and the leading syndrome elements were blood stasis (22.12%), yin deficiency (15.93%), and qi deficiency (15.04%). In the HCC stage, the syndrome was dominated by blood stasis obstructing the collaterals (33.34%) and liver-kidney yin deficiency (19.73%), with the main syndrome elements being blood stasis (24.52%), yin deficiency (16.09%), and qi deficiency (15.33%). During the progression of CHB to malignancy, there was a gradual decrease in excess syndromes including liver-gallbladder damp-heat and water-dampness internal obstruction from 21.67% to 19.04%. In contrast, deficiency syndromes including liver-kidney yin deficiency and spleen-kidney yang deficiency increased from 15.83% to 31.97%. Additionally, excess syndrome elements including qi stagnation, heat and dampness decreased from 59.89% to 34.48%, while deficiency syndrome elements including qi deficiency, yin deficiency and yang deficiency increased from 32.30% to 41.00%. ConclusionDuring the malignant transformation of CHB, there exists a progression of syndrome and syndrome elements, shifting from qi stagnation, heat and qi deficiency to blood stasis (predominantly excess), dampness and qi deficiency, and then to blood stasis (predominantly deficiency), yin deficiency and qi deficiency, characterized by “deficiency-excess complex, and shift from excess to deficiency”.

ABSTRACT

Objective:To investigate the role and underlying mechanisms of inhibiting high mobility group box-1 (HMGB1) in the expression of matrix metalloproteinase-9 (MMP-9) in spinal cord astrocytes (AS) in rats after spinal cord injury (SCI).Methods:After an SCI model was established in Sprague-Dawley (SD) rats using a modified Allen's Weight-Dropping method and ethyl pyruvate (EP) or glycyrrhizin (GL) was used to inhibit the effect of HMGB1, the rats were divided into a sham group, an SCI group, an SCI+EP (50 mg/kg) group, and an SCI+GL (100 mg/kg) group. The expression levels of glial fibrillary acid protein (GFAP) and MMP-9 in spinal cord AS were observed. After the spinal cord AS in SD rats was cultured and incubated by the oxygen-glucose deprivation/reoxygenation (OGD/R) procedure, the expression of MMP-9 protein was detected at 6 h/R 6 h, 12 h, 24 h, and 48 h after OGD. The time point with the highest expression was chosen in the subsequent experiments as an OGD/R group. HMGB1 was inhibited by HMGB1 shRNA or EP to observe the effect of HMGB1 on the expression of MMP-9 protein in AS treated with OGD/R. Then, toll-like receptor 4 (TLR4) inhibitor, TIR-domain-containing adaptor inducing interferon- β (TRIF) inhibitor, and nuclear factor-kappa B (NF- κB) inhibitor were used to investigate the effects of TLR4/TRIF/NF- κB signaling pathway during the regulation of HMGB1 on MMP-9 in vitro. Results:Western blot showed that the expression of MMP-9 protein in the spinal cord was significantly increased in rats at 1 d after SCI, and the expression of MMP-9 protein in the SCI+EP group and the SCI+GL group was significantly lower than that in the SCI group ( P<0.001). Immunofluorescence showed that GFAP and MMP-9 proteins were co-localized in the spinal cord after SCI, and the expression of GFAP and MMP-9 proteins in the SCI+EP and SCI+GL groups was significantly lower than that in the SCI group ( P<0.05). Since the expression of MMP-9 protein in the spinal cord AS cultured in vitro was significantly higher in the OGD 6h/R 12h group than that in the normal group and the OGD 6h/R 6h, 24, and 48 h groups, the OGD 6h/R 12h was taken as the OGD/R group. The MMP-9 protein expression in AS in the OGD/R+HMGB1 shRNA group and the OGD/R+EP group was significantly lower than that in the OGD/R group ( P<0.001). In the cultured AS, moreover, inhibiting TLR4, TRIF, and NF- κB reduced MMP-9 protein expression after OGD 6 h/R 12 h when compared with that in the OGD/R group ( P<0.001). Conclusions:HMGB1 inhibition may result in a reduction in MMP-9 expression both in the spinal cord AS in SCI rats and in AS after OGD/R treatment in vitro. HMGB1 may regulate MMP-9 protein expression in AS after OGD/R treatment via the TLR4/TRIF/NF- κB signal pathway.

ABSTRACT

Long non-coding RNAs (lncRNAs) play a significant role in maintaining tissue morphology and functions, and their precise regulatory effectiveness is closely related to expression patterns. However, the spatial expression patterns of lncRNAs in humans are poorly characterized. Here, we constructed five comprehensive transcriptomic atlases of human lncRNAs covering thousands of major tissue samples in normal and disease states. The lncRNA transcriptomes exhibited high consistency within the same tissues across resources, and even higher complexity in specialized tissues. Tissue-elevated (TE) lncRNAs were identified in each resource and robust TE lncRNAs were refined by integrative analysis. We detected 1 to 4684 robust TE lncRNAs across tissues; the highest number was in testis tissue, followed by brain tissue. Functional analyses of TE lncRNAs indicated important roles in corresponding tissue-related pathways. Moreover, we found that the expression features of robust TE lncRNAs made them be effective biomarkers to distinguish tissues; TE lncRNAs also tended to be associated with cancer, and exhibited differential expression or were correlated with patient survival. In summary, spatial classification of lncRNAs is the starting point for elucidating the function of lncRNAs in both maintenance of tissue morphology and progress of tissue-constricted diseases.

ABSTRACT

In recent years, the development of bispecific antibodies (bsAbs) has been rapid, with many new structures and target combinations being created. The boom in bsAbs has led to the successive issuance of industry guidance for their development in the US and China. However, there is a high degree of similarity in target selection, which could affect the development of diversity in bsAbs. This review presents a classification of various bsAbs for cancer therapy based on structure and target selection and examines the advantages of bsAbs over monoclonal antibodies (mAbs). Through database research, we have identified the preferences of available bsAbs combinations, suggesting rational target selection options and warning of potential wastage of medical resources. We have also compared the US and Chinese guidelines for bsAbs in order to provide a reference for their development.

ABSTRACT

Objective:To investigate the knowledge and compliance status of prevention and control of brucellosis among high-risk populations in counties and districts with high incidence of brucellosis in Xinjiang Uygur Autonomous Region (Xinjiang for brief), and to provide scientific basis for prevention and control of brucellosis and health education for high-risk populations.Methods:Huocheng County, a high incidence county of brucellosis in Xinjiang, was selected as the survey site. Three to six townships were selected, and two to three administrative villages were selected from each township as the survey villages. People over 18 years old and engaged in livestock breeding such as cattle and sheep breeders, livestock product processors, veterinarians and medical personnel were selected as the survey subjects. Face-to-face surveys were conducted by professional trained investigators in autumn and winter (December 2019 to January 2020) and spring and summer (April to July 2020). The survey included general demographic information, awareness of brucellosis prevention and control knowledge and the use of protective equipment.Results:A total of 600 people were surveyed, and 597 people completed the questionnaire, with an effective response rate of 99.50% (597/600). The overall awareness rate of brucellosis prevention and control knowledge was 68.23% (10 184/14 925), among which the awareness rate of clinical symptoms of human infection with brucellosis was high, at 73.53% (3 073/4 179). There were statistically significant differences in the awareness rate of main source of infection, main transmission route and clinical symptoms of human infection with brucellosis among people of different gender, age, nationality, education level and occupation ( P < 0.05). Among them, the awareness rate of clinical symptoms of human infection with brucellosis among veterinarians and medical personnel was 85.38% (514/602). The utilization rate of protective equipment such as rubber shoes and work clothes was high, which was 63.48% (379/597) and 60.97% (364/597), respectively. There were statistically significant differences in the utilization rate of protective equipment among different nationality, education level and occupation ( P < 0.05). Among them, The utilization rate of work clothes was the highest among people with college education or above, veterinarians and medical personnel, which was 82.61% (57/69) and 93.02% (80/86), respectively. Conclusions:The overall awareness rate of brucellosis prevention and control knowledge in high-risk groups in Huocheng County of Xinjiang is low, especially among high-risk groups such as those who are illiterate or have little literacy, and farmers, the awareness rate is low and the awareness of prevention and control is weak. There is a risk of brucellosis infection. It is necessary to further strengthen the education of brucellosis prevention and control knowledge among these groups.

ABSTRACT

Objective To investigate the clinical efficacy and related adverse reactions of the combination of camrelizumab with anlotinib as the third-line therapy on advanced non-small cell lung cancer. Methods We retrospectively analyzed the clinical data of 84 patients with advanced non-small cell lung cancer after second-line treatment. According to different treatment methods, 44 patients who received camrelizumab combined with anlotinib were included in the observation group, and 40 patients who received anlotinib alone were included in the control group. The PFS, ORR, DCR and incidence of adverse reactions were analyzed and compared between the two groups. Results The median PFS of the observation group was longer than that of the control group (7.0 vs. 5.6 months, P=0.001). No statistically significant difference was observed in ORR, DCR, the incidence of adverse reactions or the incidence of adverse reactions above grade 3 between two groups (all P > 0.05). Conclusion The clinical efficacy of camrelizumab combined with anlotinib as third-line therapy on advanced non-small cell lung cancer is better than anlotinib alone, and the safety is good.

ABSTRACT

Objective:To evaluate the optimization efficacy of anterior quadratus lumborum block at supra-arcuate ligament (SA-AQLB) combined with general anesthesia for laparoscopic gynecological surgery.Methods:Eighty American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients, aged 28-64 yr, weighing 52-78 kg, with height of 154-166 cm, scheduled for elective laparoscopic gynecological surgery, were divided into general anesthesia group (group G, n=40) and SA-AQLB combined with general anesthesia group (group SG, n=40) using a random number table method.In group SG, bilateral SA-AQLB was performed under ultrasound guidance before anesthesia induction, and 0.4% ropivacaine 25 ml plus dexamethasone 5 mg was injected into both sides.Combined intravenous-inhalational anesthesia was applied in both groups.Patient-controlled intravenous analgesia (PCIA) with sufentanil 2 μg/kg (in 150 ml of normal saline) was performed after surgery.The PCIA pump was set up to deliver a 2 ml bolus dose with a 15-min lockout interval and background infusion at 2 ml/h.Visual analogue scale (VAS) scores for abdomen, pelvis and shoulder pain were recorded at 1, 6, 12, 24 and 48 h after operation.Flurbiprofen was used for rescue analgesia when VAS score >4.The occurrence of intraoperative cardiovascular events and amount of sufentanil used during operation were recorded.The time to first pressing the analgesia pump, effective pressing times of PCA, requirement for rescue analgesia and consumption of sufentanil after operation were recorded.The extubation time, time to first flatus after operation, first ambulation time, length of hospital stay and development of postoperative adverse reactions such as nausea and vomiting, urinary retention and respiratory depression within 48 h after operation were recorded. Results:Compared with group G, the incidence of intraoperative hypertension and tachycardia was significantly decreased, the incidence of intraoperative hypotension and bradycardia was increased, the intraoperative consumption of sufentanil was reduced, the extubation time was shortened, the time to first pressing the analgesia pump was prolonged, the effective pressing times of PCA, requirement for rescue analgesia and postoperative consumption of sufentanil were reduced, the time to first flatus, first ambulation time and length of hospital stay were shortened, VAS scores for abdomen, pelvis and shoulder pain were decreased at each time point after operation, and the incidence of nausea and vomiting, urinary retention and respiratory depression after operation was decreased in group SG ( P<0.01). Conclusions:Compared with general anesthesia, the combination of SA-AQLB and general anesthesia can reduce the opioid consumption, inhibit intraoperative stress responses and postoperative hyperalgesia and promote early postoperative recovery when used for the patients undergoing laparoscopic gynecological surgery.

ABSTRACT

【Objective】 To analyze and master the serological and genetic characteristics of the samples with CisAB subtype and their genetic background. 【Methods】 From January 2018 to January 2022, blood samples with discrepant ABO blood typing results, from Zhengzhou voluntary blood donors and hospital patients, were subjected to phenotypic classification using micro column gel card and tube method, as well as amplification of exons 6 and 7 in ABO gene using PCR. The pedigrees of individuals with the same CisAB subtype but different serological typing results in the same family were analyzed. 【Results】 11 The forward typing of 12 samples was AB type, and unexpected antibodies against weaker antigens were found in 11 serum samples, including 9 cases with strong antigen A, 2 cases with strong antigen B, and 1 case with consistent forward and reverse typing results. Gene sequencing confirmed that 11 cases were CisAB01 subtype and 1 case was CisAB05 subtype.Among them, 7 cases had the genotype of CisAB01/O and serological phenotype of A2B3; 2 cases had the genotype of CisAB01/B and phenotype of A2B; 2 cases had the genotype of CisAB01/A and serological phenotype of A1Bx and A1B3; 1 case had the phenotype of AxB. In the CisAB01 family, 1 case of CisAB01/O with A2B3 phenotype and 1 case of CisAB01/B with A2B phenotype were detected. In the CisAB05 family, 2 CisAB05/O01 and 1 CisAB05/O02 were detected. 【Conclusion】 The serological phenotypes of different individuals in the same CisAB01 family can be different when paired with different ABO alleles. It is advisable to accurately identify the CisAB subtype genes with molecular biological methods to ensure blood transfusion safety.

ABSTRACT

Cryptogenic stroke (CS) is a type of stroke that can not find the exact cause after using the standard clinical examination procedure of stroke. In recent years, many studies have shown that patent foramen ovale (PFO) is closely associated with CS, and its main pathogenesis is paradoxical embolism. In clinical practice, ultrasound is often used for PFO screening. In the context of PFO, the secondary prevention of CS includes drug therapy and PFO closure, but the choice of treatment is still controversial. Screening and evaluation of possible PFO will help to develop secondary prevention strategies for patients with CS, especially those who can benefit from PFO closure.

ABSTRACT

Environmental threats often trigger innate defensive responses in mammals. However, the gradual development of functional properties of these responses during the postnatal development stage remains unclear. Here, we report that looming stimulation in mice evoked flight behavior commencing at P14-16 and had fully developed by P20-24. The visual-evoked innate defensive response was not significantly altered by sensory deprivation at an early postnatal stage. Furthermore, the percentages of wide-field and horizontal cells in the superior colliculus were notably elevated at P20-24. Our findings define a developmental time window for the formation of the visual innate defense response during the early postnatal period and provide important insight into the underlying mechanism.

ABSTRACT

Objective To investigate the clinical applicability and different characteristics of three commonly used diagnostic methods for drug-induced liver injury from the two aspects of liver injury induced by Western medicine and liver injury induced by traditional Chinese medicine. Methods A prospective cohort study was performed for 289 hospitalized patients with acute drug-induced liver injury who were admitted to The Fifth Medical Center of Chinese PLA General Hospital from January 2015 to December 2020 and did not receive integrated traditional Chinese and Western medicine therapy, among whom 187 patients had herb-induced liver injury and 102 had Western medicine-induced liver injury. The 289 patients were diagnosed by the integrated evidence chain (IEC), Roussel Uclaf Causality Assessment Method (RUCAM), and the Structured Expert Opinion Process (SEOP) method, and related data at acute onset were collected, including general information, latency period, detailed medication, and laboratory markers such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase, alkaline phosphatase, and total bilirubin. A statistical analysis was performed to investigate the consistency between IEC, RUCAM, and SEOP in the diagnosis of Western medicine-induced liver injury and herb-induced liver injury and their own applicability. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data; the chi-square was used for comparison of categorical data. Results The hepatocellular type was the main type of clinical liver injury in both Western medicine-induced liver injury and herb-induced liver injury, accounting for 81.4% and 74.3%, respectively, and laboratory examination showed higher levels of ALT and AST. Western medicine-induced liver injury cases were diagnosed by IEC, RUCAM, and SEOP, with a clinical diagnosis rate of 65.7%, 100%, and 63.7%, respectively, and the constituent ratio of Western medicine-induced liver injury was 23.2%, 35.3%, and 22.5%, respectively. Herb-induced liver injury cases were diagnosed by these three methods, with a clinical diagnosis rate of 47.6%, 100%, and 29.9%, respectively, and the constituent ratio of herb-induced liver injury was 30.8%, 64.7%, and 19.4%, respectively. The consistency test of the three diagnostic methods showed that in the diagnosis of Western medicine-induced liver injury cases, there was good consistency between IEC and SEOP (Kappa=0.785, P 0.05) and between RUCAM and SEOP (Kappa=0.117, P > 0.05); in the diagnosis of herb-induced liver injury cases, there was poor consistency between RUCAM and SEOP (Kappa=0.066, P > 0.05), while there was good consistency between RUCAM and IEC (Kappa=0.026, P < 0.05) and between IEC and SEOP (Kappa=0.437, P < 0.05). Conclusion The IEC method shows good applicability for both Western medicine-induced liver injury and herb-induced liver injury, and there is good consistency between IEC and SEOP in the diagnosis of Western medicine-induced liver injury cases, while there is a relatively low level of consistency between IEC and SEOP in the diagnosis of herb-induced liver injury. There is poor consistency between RUCAM and the other two methods. In the clinical diagnosis of Western medicine-induced liver injury, IEC, RUCAM, and SEOP should be used in combination to accurately judge the causal relationship between drugs and liver injury.

ABSTRACT

Objective:To study the changes of cytokines after cardiopulmonary bypass(CPB)in children with congenital heart disease.Methods:A total of 124 children with congenital heart disease underwent CPB surgery at Shanghai Children′s Medical Center from June 2020 to October 2021 with cytokine detection were enrolled.Twelve kinds of cytokines, white blood cell count(WBC)and neutrophil-to-lymphocyte ratio(NLR), C-reactive protein(CRP)and procalcitonin were detected before and 24 hours after operation.All patients were divided into CPB<120 min group ( n=102)and CPB≥120 min group ( n=22)acoording to CPB time, and were divided into systemic inflammatory response syndrome (SIRS) group, compensatory anti-inflammatory response syndrome (CARS) group and control group according to the changes of cytokines.The changes of cytokines, anti-inflammatory factors and pro-inflammatory factors before and after CPB and the correlation with CPB time were analyzed. Results:There were 65 boys and 59 girls with a body weight of(10.69±8.18)kg and a median age of 317(141, 975)d.After CPB, WBC(×10 9/L)(13.47 vs.8.6), NLR(4.93 vs.0.55), and CRP(mg/L)(81.35 vs.0.8) were significantly higher than those before operation( P<0.001). IL-6(pg/mL)(135.69 vs.6.86), IL-8(pg/mL)(33.33 vs.14.95), and IL-10(pg/mL)(6.05 vs.2.44)were significantly higher than those before operation( P<0.001). Compared with CPB<120 min group, IL-6(pg/mL)(211.88 vs.119.47), IL-8(pg/mL)(71.67 vs. 25.39), and IL-10(pg/mL)(7.69 vs. 4.92)in CPB≥120 min group significantly increased( P<0.001). CRP was negatively correlated with CPB time( r=-0.204, P=0.025), while IL-6( r=0.254, P=0.005), IL-8( r=0.358, P=0.001), IL-10( r=0.198, P=0.03) were positively correlated with CPB time.Twelve children(9.7%)had obvious SIRS, and four cases(3.2%)had early CARS.The mortality of CARS group was significantly higher than that of SIRS group and the control group( P=0.011). Conclusion:Il-6 , IL-8, and IL-10 are significantly increased after CPB in children with congenital heart disease.With the increase of CPB time, IL-6 and IL-8 increase significantly, and the correlation between IL-8 and CPB time is the strongest.Although the proportion of children with early postoperative CARS is small, the mortality is high, which indicates clinical surveillance and treatment need to be strengthened for anti-inflammatory response.

ABSTRACT

Objective:To analyze the risk factors of performing diaphragm plication(DPL) after congenital heart disease(CHD) surgery as well as the timing and clinical efficacy.Methods:Data regarding children underwent open heart surgery at Shanghai Children′s Medical Center from January 2017 to December 2019 were reviewed.According to whether DPL was performed after CHD operation or not, the children were divided into DPL group and non-diaphragm plication(NDPL)group.Clinical data including age, surgery, cardiopulmonary bypass(CPB)temperature and time of two groups were compared, meanwhile the risk factors of DPL surgery were analyzed.Based on the median of 8 days between open heart surgery and DPL, children in DPL group were divided into early surgery group(less than 8 days), and delayed operation group(no less than 8 days). The parameters of comparison included ventilator using time, hospital stay time, hospitalization expenditure, postoperative infection to evaluate the timing of DPL and effect.Results:There were 10 309 children after CHD, including 95 in DPL group and 10 214 in NDPL group.In DPL group, there were 52 males(54.7%) and 43 females(45.3%), with age 147(52, 318) d, weight(5.5±4.1) kg, height(56.8±25.6) cm, CPB time(136.8±93.4) min and aortic occlusion time(62.5±50.2) min.Compared with NDPL group, DPL group had younger age, shorter height, lighter weight, higher incidence of preoperative special treatment, higher proportion of reoperation, lower CPB temperature, longer CPB time and longer aortic occlusion time.There were significant differences between two groups( P<0.05). Multivariate Logistic regression analysis showed that younger operative age( OR=0.998, 95% CI 0.998~0.999, P<0.001), staging operation( OR=72.977, 95% CI 39.096~136.211, P<0.001), long CPB time( OR=1.006, 95% CI 1.002~1.011, P=0.008), and pulmonary venoplasty( OR=4.219, 95% CI 2.132~8.350, P<0.001) were independent risk factors for DPL after CHD.Early surgery group had lower postoperative infection rate(43.59% vs. 88.38%, P=0.007), shorter ventilator duration[168.0(99.5, 280.5) h vs.309.9(166.2, 644.5) h, P=0.029], shorter hospital stay duration[27.00(20.75, 35.00)d vs.37.00(28.00, 53.00)d, P<0.001], and lower hospitalization cost[158.36(128.99, 203.11) thousand yuan vs.232.95(174.54, 316.47) thousand yuan, P<0.001] than delayed operation group. Conclusion:Younger age, staging operation, long CPB time, and pulmonary venoplasty are independent risk factors for DPL due to diaphragmatic paralysis after pediatric CHD surgery.Early surgical intervention is beneficial for the recovery of children.

ABSTRACT

Objective:To explore the association between attitudes toward care of the dying and death depression in undergraduate nursing students.Methods:With stratified sampling, 380 undergraduate nursing students in Guangdong Medical University from June to September 2020 were investigated by using a self-designed questionnaire, Frommelt Attitudes Toward Care of the Dying Scale Form B (FATCOD-B-C) and Chinese version of Death Depression Scale-Revised (CCDS-R). Pearson correlation analysis was used to analyze the correlation between hospice care attitude and death depression of nursing undergraduates.Results:The score of FATCOD-B-C of 380 nursing undergraduates was (104.92 ± 7.92) points. The highest average score of dimensions of attitude toward the necessity of family support was (4.02 ± 0.38) points, and the lowest average score of dimensions of attitude toward communication with the dying person was (2.95 ± 0.42) points. The score of CCDS-R was (54.58 ± 12.52) points. The highest average score of dimensions of other death was (3.48 ± 0.80) points, and the lowest average score of dimensions of existential vacuum was (1.78 ± 0.69) points. Pearson analysis revealed that attitudes toward care of the dying had a negative association with death depression ( r=-0.34, P<0.05). Conclusions:Attitudes toward care of the dying of undergraduate nursing students is in a higher level and it has close association with death depression. It is recommended to reduce the death depression level of undergraduate nursing students through hospice care training and carrying out death education, so as to improve the positive attitudes of caring for dying patients.

ABSTRACT

Objective:To investigate the potential risk factors for cryptogenic stroke (CS) in patients with patent foramen ovale (PFO).Methods:Patients underwent PFO closure in the Department of Cardiovascular Surgery, the Second Hospital of Hebei Medical University from June 2018 to December 2021 were enrolled retrospectively. Transesophageal echocardiography was used to evaluate the morphological characteristics of foramen ovale and right-to-left shunt (RLS). Multivariate logistic regression analysis was used to determine the independent risk factors for CS in patients with PFO. Results:A total of 203 patients with PFO were enrolled. Their age was 41.9±14.3, and 116 patients (57.1%) were male. There were 102 patients in CS group and 101 patients in non-stroke group. The age, body mass index, systolic blood pressure and diastolic blood pressure, and the constituent ratios of male, hypertension, diabetes, hyperlipidemia and smoking of the CS group were significant higher than those of the non-stroke group (all P<0.05). The PFO channel of the CS group was longer, wider and more combined with resting RLS (all P<0.05). Multivariate logistic regression analysis showed that systolic blood pressure (odds ratio [ OR] 1.065, 95% confidence interval [ CI] 1.022-1.111; P=0.003), PFO length ( OR 1.124, 95% CI 1.004-1.258; P=0.043) and resting RLS ( OR 5.449, 95% CI 2.283-13.004; P<0.001) were the independent risk factors for CS in patients with PFO. Conclusion:Systolic blood pressure, PFO length and the presence of resting RLS are the independent risk factors for CS in patients with PFO.

ABSTRACT

Measuring eye movement is a fundamental approach in cognitive science as it provides a variety of insightful parameters that reflect brain states such as visual attention and emotions. Combining eye-tracking with multimodal neural recordings or manipulation techniques is beneficial for understanding the neural substrates of cognitive function. Many commercially-available and custom-built systems have been widely applied to awake, head-fixed small animals. However, the existing eye-tracking systems used in freely-moving animals are still limited in terms of their compatibility with other devices and of the algorithm used to detect eye movements. Here, we report a novel system that integrates a general-purpose, easily compatible eye-tracking hardware with a robust eye feature-detection algorithm. With ultra-light hardware and a detachable design, the system allows for more implants to be added to the animal's exposed head and has a precise synchronization module to coordinate with other neural implants. Moreover, we systematically compared the performance of existing commonly-used pupil-detection approaches, and demonstrated that the proposed adaptive pupil feature-detection algorithm allows the analysis of more complex and dynamic eye-tracking data in free-moving animals. Synchronized eye-tracking and electroencephalogram recordings, as well as algorithm validation under five noise conditions, suggested that our system is flexibly adaptable and can be combined with a wide range of neural manipulation and recording technologies.

ABSTRACT

Understanding the connection between brain and behavior in animals requires precise monitoring of their behaviors in three-dimensional (3-D) space. However, there is no available three-dimensional behavior capture system that focuses on rodents. Here, we present MouseVenue3D, an automated and low-cost system for the efficient capture of 3-D skeleton trajectories in markerless rodents. We improved the most time-consuming step in 3-D behavior capturing by developing an automatic calibration module. Then, we validated this process in behavior recognition tasks, and showed that 3-D behavioral data achieved higher accuracy than 2-D data. Subsequently, MouseVenue3D was combined with fast high-resolution miniature two-photon microscopy for synchronous neural recording and behavioral tracking in the freely-moving mouse. Finally, we successfully decoded spontaneous neuronal activity from the 3-D behavior of mice. Our findings reveal that subtle, spontaneous behavior modules are strongly correlated with spontaneous neuronal activity patterns.

ABSTRACT

A strong animal survival instinct is to approach objects and situations that are of benefit and to avoid risk. In humans, a large proportion of mental disorders are accompanied by impairments in risk avoidance. One of the most important genes involved in mental disorders is disrupted-in-schizophrenia-1 (DISC1), and animal models in which this gene has some level of dysfunction show emotion-related impairments. However, it is not known whether DISC1 mouse models have an impairment in avoiding potential risks. In the present study, we used DISC1-N terminal truncation (DISC1-N
