ABSTRACT
Galectin-9 （Gal-9） is a member of the galectin family that can specifically recognize and bind to galactosides. Recent studies have shown that Gal-9 is highly expressed in the liver and can help to maintain intrahepatic immune homeostasis and perform biological functions in various liver diseases. This article reviews the immunomodulatory functions of Gal-9 and its role in different liver diseases. Studies have shown that Gal-9 has important biological functions in different liver diseases through multiple pathways. Research on the specific immunomodulatory mechanisms and functions of Gal-9 may help to discover the therapeutic role of Gal-9 in liver diseases.
ABSTRACT
In order to understand nurses’ willingness to participate in humanistic nursing training and its influencing factors, and provide reference for managers to understand the current situation and improve nurses’ enthusiasm for humanistic nursing training. The convenience sampling method was used to investigate 23 707 nurses in 28 provinces (autonomous regions and municipalities directly under the central government) through a self-designed questionnaire distributed on the Internet. The results showed that 98.1% of nurses thought that participating in humanistic nursing related training was helpful to clinical work, but only 88.6% of the respondents were willing to participate in humanistic nursing training. Thirty factors were analyzed from four aspects of basic characteristics of individuals, cognitive relevant experience and organizational atmosphere. Fifteen factors had significant significance in binary Logistic regression analysis (P<0.05). Among them, the factors that had a positive impact on training willingness were: marriage, education, professional title, post establishment, agree with humanistic care is the basic duty of a nurse praised, experience of being praised at work, family support, rapport with patients, passion of colleagues to participate in training, sustained high-quality care demonstration activities, join the humanistic care related organization, hospital reimbursement of training expenses (OR value of 6.559~1.113, P<0.001). The OR value of humanistic nursing as a nurse’s responsibility was 6.559 and the 95%CI was 5.585~7.702. The factors that hindered nurses from participating in training were: work occupied most of time and energy, think humanistic nursing is abstract and difficult to understand, think the mastered humanistic knowledge and skills meet the needs of work (OR value of 0.657~0.722, P<0.001). Through the analysis, it is considered that nurses have a extremely consistent high recognition of the significance of humanistic nursing training, but their willingness to receive training is affected by many factors such as individual experience, cognitive attitude and organizational atmosphere. In order to realize nurses’ high recognition of humanistic nursing training to high enthusiasm of behavior, the aspects of individual cognition and organizational atmosphere must be discussed.
ABSTRACT
Objective:To study the anatomy of the perforator propeller flap of superior lateral genicular artery, and to explore a surgical method and clinical application in repair of the soft tissue defect of anterolateral knee with the flap.Methods:From September 2019 to September 2021, 8 knees of 4 chilled fresh specimen of adults were studied. The perforators of the superior lateral genicular artery were observed. The length, outer diameter of the perforators, and the locations of the skin perforation were recorded. The superior lateral genicular artery perforator propeller flaps were then applied clinically to 5 patients(3 males and 2 females) with soft tissue defects of anterolateral knee. Two of the patients had combined ligament injury and(or) bone joint exposure. The age of patients ranged from 25 to 48 years old, at 33.4 years old in average. The sizes of soft tissue defects ranged from 4.0 cm×4.0 cm to 8.0 cm×5.0 cm. The sizes of perforator propeller flaps of superior lateral genicular artery were 10.0 cm×5.0 cm to 13.0 cm×6.0 cm. The superior perforating vessels of the superior lateral genicular artery were found and marked at the points of skin perforation. Preoperative contrast-enhanced ultrasound were performed to confirm the dominant perforating vessels and had the skin perforating points marked. Intraoperative CDU were further performed to confirm the points of dominant perforating vessels. Perforator propeller flaps were designed depending on the size of the anterolateral soft tissue defect, and flaps were prepared and transferred to the defect sites. Postoperative follow-ups were conducted at outpatient clinic. The survival of the flap and knee function were observed according to the Bai-ly knee scoring.Results:The anatomy showed that an average pedicle length of the superior lateral genicular artery perforator was(8.2±0.9) cm, with an average starting outer diameter at(1.1±0.2) mm. All 5 flaps survived during the follow-up that lasted for 10 to 24 months, with an average of 15.3 months. All flaps healed in 2 weeks after surgery without complications such as soft tissue infection, bone and joint infection were observed. At the last follow-up, no obvious bloated appearance of the flaps were observed. The colour and elasticity of the flaps were similar to the surrounding skin. The knee function was assessed: 4 patients were in excellent and 1 in good. The range of knee flexion and extension was from 100° to 150°. The patients were satisfied with the appearance and function of the knees.Conclusion:The size of the perforator of superior lateral genicular artery and the pedicle length are ideal. The propeller flap can be used to repair the soft tissue defect around the anterolateral knee, with satisfactory functional recovery of a knee. It is a good method to repair the soft tissue defect around anterolateral knee.
ABSTRACT
We report a case of a female teenage with monogenic diabetes mellitus caused by glucokinase regulator (GCKR) gene mutation who presented with diabetic ketosis and misdiagnosed as type 1 diabetes. The patient was treated with insulin for 3 years since diagnosis. The islet function was well preserved, but polycystic ovary syndrome was developed. Whole-exome gene sequencing revealed a GCKR gene c. 69delG heterozygous mutation. After molecular diagnosis, the insulin dosage was gradually reduced to full cessation, and only metformin sustained-release tablets were taken to control blood glucose. It is necessary to regular evaluate islet function of patient with type 1 diabetes, and genetic test is of significance for accurate diagnosis and treatment.
ABSTRACT
Objective:To analyze the correlation between the volume of irradiated pelvic bone marrow and acute hematologic toxicity (HT), in order to provide clinical data to reduce the risk of acute HT and optimize the radiotherapy plan.Methods:From October 2017 to May 2019, 41 LARC patients who received neoadjuvant concurrent chemoradiotherapy (CCRT) were retrospectively reviewed in our center. All patients were treated with 5-field intensity-modulated radiotherapy (IMRT), and the prescription dose delivered to PTV was 45-50.4 Gy in 25-28 fractions. Capecitabine or 5-fluorouracil (5-FU) wasadministered daily 5 days a week during radiotherapy. Different HTswere recorded according to National Cancer Institute Common Toxicity Criteria Version 5.0 (NCI-CTC.V5.0) based on laboratory tests. The volume of PBM or each site (coxal, sacrum, femoral) receiving more than x Gy refers to as TVx, CVx, SVx, and FVx, respectively. Logistic regression was performed to evaluate the association between the volume of irradiated pelvic bone marrow and different HT. Generalized additive model (GAM) and piecewise regression were used to further analyze the possible nonlinear relationship and threshold effect between them. Results:Multivariate logistic regression analysis showed that low-dose of irradiated total pelvic bone marrow volume ( TV5) and coxal bone marrow volume ( CV5, CV10) were significantly correlated with Grade ≥2 leukopenia( P<0.05). There was a significant negative correlation between the sacrum bone marrow volume ( SV5, SV10) and Grade ≥2 leukopenia ( P<0.05). A thresholdeffect has been observed between CV10 and Grade ≥2 leukopenia by Generalized additive model (GAM) and piecewise linear regression. The threshold between CV10 and Grade ≥2 leukopenia was 575 ml, OR (95% CI) was 1.85 (1.08, 3.16). Conclusions:In neoadjuvant IMRT of rectal cancer, CV is a better predictor of acute HT induced by CCRT than TV. The irradiated volume of CV associated with acute HT was mainly low-dose levels ( CV5, CV10). The thresholds of our study ( CV10= 575 ml) could be a good reference for the optimization of the radiotherapy plan.
ABSTRACT
Objective:To explore the oxidative stress of cerebral white matter lesion (WML) and normal-appearing white matter (NAWM) with in vivo proton exchange rate (k ex) MRI on relapse-remitting multiple sclerosis (RRMS) patients. Methods:Clinical and imaging data of 37 patients (case group) with RRMS patients of Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology were analyzed retrospectively from November 2018 to November 2021, including 11 males and 26 females aged 18-41 (29±7) years. Another 22 age-matched healthy volunteers (control group) were recruited for the same period, including 4 males and 18 females aged 23-44 years with a median age of 25 (24, 28.25) years. All subjects received conventional MR protocols and chemical exchange saturation transfer imaging. The manifestation of WML on the k ex map and T 1WI images were assessed while the k ex values of WML, NAWM and normal white matter (NWM) of control group were quantitatively evaluated. Student′s t test was used to compare the k ex difference of WML and NAWM in the case group, NAWM in the case group and NWM in the control group, low-signal and isosignal WML in T 1WI. Spearman rank correlation was used to analyze the correlation of the k ex values of WML with patients′ expanded disability status scale (EDSS) score. Results:A total of 272 WML were found in the 37 RRMS patients, and 25.4% (69/272) were T 1-hypointense. The k ex value of WML in the case group [(932±108) s -1] was higher than that of NAWM [(771±26) s -1], and the difference was statistically significant ( t=8.95, P<0.001); the k ex value of NAWM in the case group [(771±26) s -1 ] was higher than that of NWM [(745±26) s -1] in the control group, and the difference was statistically significant ( t=3.96, P<0.001). The k ex value [(1 039±110) s -1] of WML with low signal at T 1WI was higher than that of WML with equal signal [(895±79) s -1], with a statistically significant difference ( t=9.78, P<0.001). Correlation analysis showed that the k ex value of WML in the case group was positively correlated with the EDSS score ( r=0.54, P<0.001). Conclusions:The elevated k ex values of WML and NAWM reflect the cerebral oxidative stress of RRMS patients and are positively correlated to the severity of tissue damage, which suggests the role of oxidative stress in RRMS lesion formation and brain atrophy.

ABSTRACT
BACKGROUND: As maize originated in tropical or subtropical zones, most maize germplasm is extremely sensitive to low temperatures during the seedling stage. Clarifying the molecular mechanism of cold acclimation would facilitate the breeding of cold tolerant maize varieties, which is one of the major sustainability factors for crop production. To meet this goal, we investigated two maize inbred lines with contrasting levels of cold tolerance at the seedling stage (IL85, a cold tolerant line; B73, a cold sensitive line), and performed full-length transcriptome sequencing on the root tips of seedlings before and after 24 h of cold treatment. RESULTS: We identified 152,263 transcripts, including 20,993 novel transcripts, and determined per-transcript expression levels. A total of 1,475 transcripts were specifically up-regulated in the cold tolerant line IL85 under cold stress. GO enrichment analysis revealed that 25 transcripts were involved in reactive oxygen species (ROS) metabolic processes and 15 transcripts were related to the response to heat. Eight genes showed specific differential alternative splicing (DAS) in IL85 under cold stress, and were mainly involved in amine metabolism. A total of 1,111 lncRNAs were further identified, 62 of which were up-regulated in IL85 or B73 under cold stress, and their corresponding target genes were enriched in protein phosphorylation. CONCLUSIONS: These results provide new insights into the molecular mechanism of cold acclimation during the seedling stage in maize, and will facilitate the development of cultivars with improved cold stress tolerance.

ABSTRACT
Background: Recent studies showed that the clinical outcome of moderately severe acute pancreatitis (MSAP) are different among different subgroups. Aims: To further subdivide MSAP, and explore the heterogeneity of MSAP subgroups. Methods: A retrospective analysis was performed on patients with acute pancreatitis (AP) from January 2016 to December 2020 at Northern Jiangsu People’s Hospital, including 538 patients with mild acute pancreatitis (MAP) and 461 patients with MSAP. MSAP patients were divided into four groups according to local complication and transient organ failure (TOF), including single acute peripancreatic fluid collection (APFC) without TOF group (group A), multiple APFC without TOF group (group B), other local complication without TOF group (group C) and TOF group (group D). The baseline data and the severity of AP among the four subgroups were compared. Meanwhile, the severity of disease between group A and MAP patients was also compared. Logistic regression analysis was used to evaluate the risk factors of MSAP. Results: Patients in group D were older than those in group A (P<0.05). There were statistically significant differences in different scoring systems among the four subgroups (P<0.05). The proportions of APACHE Ⅱ≥8, Glasgow≥3 and BISAP≥3 in group D were significantly higher than those in the other three groups (P<0.05). There were significant differences in levels of Ca

Objective@#To understand the neglect status among preschool non-only-child in Nantong, and to provide theoretical basis for the prevention and intervention of non-only child neglect.@*Methods@#Using the method of random cluster sampling, a total of 1 141 parents of children from 9 kindergartens in the main urban area of Nantong were investigated with National Neglect Norm Scale for Children aged 3 to 6 years.@*Results@#The neglect rate of preschool children in Nantong City was 28.6%, with neglect score being (40.21±6.67). The neglect rate of non-only-child was 32.6%, with neglect score being (41.14±6.73). The total and physical neglect rate of non-only-child were higher than that of only child, and the total neglect score and physical, emotional, educational, safety, medical neglect dimensional scores were higher than that of only-child, the difference were all statistically significant ( χ 2/ t = 6.21, 17.57; 3.95, 4.98, 3.45, 2.70, 2.01, 3.11, P <0.05). In non-only-child, univariate analysis showed that there were no significant differences in neglect rate and scores among children by gender and family types ( P >0.05); There was no significant difference in the child neglect rate between different age groups and children in different families ( χ 2 =3.59, 2.99, P >0.05), but there was a statistically significant difference in the degree of neglect ( t=2.79, 3.04, P <0.05). The neglect rate and score of non-only-child with high level of family income, parental education and parental relationship was relatively low, while the neglect rate and score in non-only-child whose grandparents serving as primary caregiver were higher ( P <0.05). Multivariate Logistic regression analysis showed that family monthly income less than 5 000 yuan was associated with 2.73 times higher risk of neglect compared to children with family monthly income more than 12 000 yuan. The risk of neglect among children whose grandparents serving as caregivers was associated with 2.17 times higher than children with parental care. The risk of neglect of children with poor parental relationship was 2.29 times higher than that of children with good parental relationship ( P <0.05).@*Conclusion@#The neglect among preschool non-only-child in Nantong City is common. Improvement in family economic status, parental care and parent relationship might help reduce neglect among preschool non-only-child.

ABSTRACT
Sepsis associated-acute kidney injury (SA-AKI) is a common complication of sepsis, which has a high incidence and is closely related to a poor prognosis. However, delayed diagnosis and non-specific treatments make it difficult to systematically manage SA-AKI. Based on massive clinical data, machine learning could build prediction models, which provide alarms and suggestions for the clinical decision support system. Although there are still many challenges such as poor interpretability, it has shown clinical application value in SA-SKI risk prediction, imaging diagnosis, subtype identification, prognosis assessment, and so on. Based on a brief introduction of machine learning, this article reviews the application, limitations, and future directions of machine learning in the diagnosis and treatment of SA-AKI, and explores the possibility of machine learning in the medical field, in order to promote the development of precision medicine and intelligent medicine.
ABSTRACT
Objective@#This study aimed to explore the feasibility of functional evaluation of the lateral pterygoid muscle (LPM) using diffusion tensor imaging (DTI) in patients with temporomandibular joint disorders (TMDs). @*Materials and Methods@#A total of 119 patients with TMD (23 male and 96 female; mean age ± standard deviation, 41 ± 15 years; 58 bilateral and 61 unilateral involvements for a total of 177 joints) and 20 healthy volunteers (9 male and 11 female;40 ± 13 years; 40 joints) were included in this prospective study. Based on DTI of the jaw in the resting state, the diffusion parameters, apparent diffusion coefficient (ADC), fractional anisotropy (FA), λ1, λ2, and λ3 of the superior and inferior heads of the LPM (SHLPM and IHLPM) were measured. Patients with TMD with normal disc position (ND), anterior disc displacement with reduction (ADWR), and anterior disc displacement without reduction (ADWOR) were compared. @*Results@#Patients with TMD overall, and ADWR and ADWOR subgroups had significantly higher ADC, λ1, λ2, and λ3 in both the SHLPM and IHLPM than those in volunteers (p < 0.05 for all), whereas the ND subgroup only had significantly higher ADC and λ1 (p < 0.001). Meanwhile, significant differences in FA in the SHLPM and IHLPM were found between volunteers and ADWOR (p = 0.014 and p = 0.037, respectively). Among the three TMD subgroups, except for λ3 and FA in the ADWR subgroup, ADWR and ADWOR subgroups had significantly higher ADC, λ1, λ2, and λ3 and lower FA than those in the ND group (p < 0.050). There was no significant difference in diffusion variables between ADWR and ADWOR. In ADWOR, the osteoarthritis group had significantly higher λ3 and lower FA values in the IHLPM than those in the non-osteoarthritis group. @*Conclusion@#DTI successfully detected functional changes in the LPM in patients with TMD. The unsynchronized diffusivity changes in the LPM in different subgroups of TMD signified the possibility of using diffusion parameters as indicators to identify the severity of LPM hyperfunction at various stages of TMD.
