Objective: To investigate the influencing factors for mild cognitive impairment (MCI) among the elderly inpatients of the department of geriatrics, so as to provide the reference for early screening and prevention of MCI in the elderly population. Methods: Inpatients aged 60 years and older and admitted to the Department of Geriatrics at the First Affiliated Hospital of Xinjiang Medical University were selected as the study subjects. Demographic information, past medical history, activities of daily living (ADL), depressive symptoms were collected through questionnaire surveys. MCI was diagnosed with Montreal Cognitive Assessment in combination with medical history and physical examination. Factors affecting MCI were identified using a multivariable logistic regression model. Results: A total of 1 019 elderly patients were collected, including 472 males (46.32%) and 547 females (53.68%), and had a median age of 73.00 (interquartile range, 14.00) years. Among them, 746 patients had an educational level of junior high school or above, accounting for 73.21%, 446 patients had cerebrovascular disease, accounting for 43.77%, and 220 patients were diagnosed with MCI, with a detection rate of 21.59%. Multivariable logistic regression analysis showed that age (OR=1.354, 95%CI: 1.285-1.426), educational level (primary school, OR=0.345, 95%CI: 0.163-0.731; junior high school or above, OR=0.196, 95%CI: 0.096-0.402), ADL (moderate/severe dependence, OR=4.744, 95%CI: 2.044-11.012) and cerebrovascular disease (OR=2.335, 95%CI: 1.482-3.679) were the influencing factors for MCI among geriatric inpatients. Conclusions The MCI of the elderly inpatients of the department of geriatrics is related to age, educational level, ADL and cerebrovascular disease. Therefore, targeted health education and cognitive function training should be provided for elderly patients to prevent MCI.

Objective:To investigate the prevalence and potential classification of symptoms after total knee arthroplasty (TKA) in patients with knee osteoarthritis (KOA), and to analyze the differences in demographic characteristics and surgical data, compare the different potential subgroups, in order to provide a basis for clinical symptom management plans.Methods:This study was a multicenter cross-sectional survey. Through convenience sampling, patients with KOA undergoing TKA in the orthopaedic wards of four tertiary hospitals in Urumqi were selected as the study from November 2023 to February 2024. The study subjects were surveyed using a general information questionnaire, the Visual Analogue Scale (VAS) for pain, the Hospital Anxiety and Depression Scale (HADS), and the Pitts Burgh Sleep Quality Index (PSQI), and the degree of postoperative joint swelling and size of ecchymosis were measured. Latent class analysis was performed using Mplus 8.3 software, and Logistic regression analysis was conducted using SPSS 26.0 software to explore the influencing factors of the latent classes.Results:Totally 337 effective questionnaires were collected, and the recovery rate was 94.7% (337/356), and the age distribution ranged from 47 to 85 (65.19 ± 6.99) years old, with 90 (26.7%) males and 247 (73.3%) females. There were 92.3% (311/337) of TKA patients with postoperative symptom cluster. The symptom cluster of patients with TKA were identified as 3 classes. They were named as "high level pain-psychological disorder group"(12.5%, 39/311), "high bruises-moderate psychological disorders group"(25.4%, 79/311) and "low symptom burden group" (62.1%, 193/311). The results of the unordered multi-class logistic regression analysis showed that age 45-59 years ( OR = 2.367), body mass index 24.0-27.9 kg/m 2 ( OR = 0.207), living with children/parents ( OR = 6.473), and this being the second joint surgery ( OR = 0.040) were the factors influencing the "high level pain-psychological disorders group" (all P<0.05). The factors influencing the "high bruises-moderate psychological disorders group" were living with children/parents ( OR = 4.023), comorbid chronic diseases ( OR = 1.979, 3.842), and intraoperative blood loss ≤100 ml ( OR = 2.342) (all P<0.05). Conclusions:The postoperative symptom cluster of TKA patients have a relatively high incidence, and there is heterogeneity within the symptom cluster, so nurses need to identify at-risk patients early according to the characteristics of different categories and give interventions.

Objective:To investigate and compare the clinical outcomes of the arterial pre-occlusion technique(APOT) and the traditional technique in the surgery of locally advanced pancreatic cancer with arterial involvement after conversion therapy.Methods:This is a retrospective cohort study. The clinical data of 145 patients with locally advanced pancreatic cancer with arterial involvement admitted to the Department of Hepato-Biliary-Pancreatic Surgery of the First Hospital Affiliated to Naval Medical University,from January 2020 to December 2022 were retrospectively analyzed. All patients completed neoadjuvant therapy for tumors, and the feasibility of radical surgical treatment was determined by a multidisciplinary collaborative team evaluation before surgery. According to whether the intraoperative artery was pre-occluded, 145 patients were divided into two groups, including 28 cases in the APOT group(16 males, 12 females, aged (59.0±9.4) years), and 117 cases in the routine surgery group(76 males, 41 females, aged (55.1±8.2) years). To ensure comparability of baseline data between the APOT group and the routine surgery group, a 1∶2 match was performed using the propensity score matching method, and the caliper value was 0.006 45. The t-test,the Mann-Whitney U test, χ2 test or Fisher′s exact test were used to compare the data between the two groups,respectively. Results:After matching the propensity score,there were 28 cases in the APOT group and 56 cases in the routine surgery group. There were no significant differences in gender,age,preoperative comorbidities,preoperative body mass index,surgical approaches,chemotherapy regimen,stereotactic body radiation therapy ratio,tumor markers,and type of invaded artery between the two groups (all P>0.05).The arterial occlusion time M(IQR) in the APOT group was 7.0(3.8)minutes(range:3 to 15 minutes),and no ischemic manifestations were observed in the distal target organs that blocked blood vessels after surgery. The operation time was (170.3±57.7)minutes in the APOT group and (235.0±80.2)minutes in the routine surgery group,and the difference was statistically significant ( t=-3.800, P<0.01). The APOT group also experienced less intraoperative blood loss(650(588)ml vs. 800(600)ml; U=1 026.500, P=0.021). No significant differences were found between the groups in combined vein resection and reconstruction,celiac trunk resection,early postoperative complications, readmission rates at 30 days,and postoperative length of stay(all P>0.05). Extra-arterial dissection was performed in all patients,with arterial resection and reconstruction in 3 cases: 2 cases in the APOT group(1 case involving the superior mesenteric artery and 1 case involving the common hepatic artery) and 1 case in the routine group(involving the common hepatic artery). Postoperative abdominal bleeding occurred in 4 cases,with 3 cases in the routine group,1 case in the routine group. The R0 resection rate was 85.7%(24/28) in the APOT group and 80.4%(45/56) in the routine group,without significant differences between the groups( P=0.763). The median overall survival time was 27.6 months for the APOT group and 22.5 months for the routine group,while the median disease-free survival was 11.7 months and 16.8 months,respectively,with no significant differences between the two groups( P=0.532, P=0.927). Conclusion:The arterial pre-occlusion technique can be used for extra-arterial dissection in patients with locally advanced pancreatic cancer involving the arteries,reducing surgery time and intraoperative blood loss.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

Objective:To explore the application value of four-dimensional automatic left ventricular quantitation(4D Auto LVQ) technology, in evaluating the myocardial mechanics in patients with different risk stratifications of hypertrophic cardiomyopathy(HCM).Methods:A total of 88 HCM patients and 20 healthy volunteers were selected from February 2020 to February 2022 in the First Affiliated Hospital of Zhengzhou University. According to the HCM Risk-SCD score, HCM patients were divided into 3 groups: low-risk group( n=49), intermediate-risk group( n=21), and high-risk group( n=18). Conventional ultrasound parameters were collected, and 4D Auto LVQ technology was used to obtain the mechanical parameters of left ventricular myocardium, including global longitudinal strain(GLS) , global circumferential strain(GCS), global area strain(GAS), global radial strain(GRS), twist and torsion. The differences in these parameters among the four groups were compared. The predictive values of conventional ultrasound parameters and myocardial mechanical parameters in patients with intermediate- and high-risk HCM patients were analyzed by ROC curve. Results:①Left ventricular end-diastolic diameter, left ventricular end-diastolic volume, left ventricular end-systolic volume, and peak systolic velocity of mitral annulus in the low-, intermediate-, and high-risk groups were lower than those in the control group while left ventricular maximal wall thickness(LVMWT) and early diastolic peak velocity of mitral value orifice/early diastolic peak velocity of mitral annulus(E/e′) were higher, left atrial diameter(LAD) and left ventricular outflow tract gradients(LVOTG) in the intermediate- and high-risk groups were higher than the low-risk group(all P<0.05). ②Compared with the control group, the GLS of HCM patients was lower, and the GLS of the intermediate- and high-risk groups was lower than the low-risk group. GCS and GRS in the intermediate- and high-risk groups were lower than those in the low-risk group. GAS in the high-risk group was lower than the low-risk and the control group, but higher than the intermediate-risk group(all P<0.05). Compared with the control group, the twist and torsion in the intermediate- and high-risk groups were higher, but lower than the low-risk group, and the differences were statistically significant(all P<0.05). ③The ROC results showed that the area under the curve(AUC) of the model containing conventional ultrasound parameters(LVWMT, LAD, and LVOTG) for predicting intermediate- and high-risk HCM patients was 0.811, with a sensitivity of 0.769 and a specificity of 0.755. The AUC of the conventional ultrasound parameters combined with myocardial mechanical parameters was 0.904, as the sensitivity was 0.667 and the specificity was 0.980. Conclusions:4D Auto LVQ can evaluate the mechanical characteristics of LV myocardium in HCM patients with different risk stratifications. Myocardial mechanical parameters combined with conventional ultrasound parameters can improve the diagnostic performance of patients with intermediate- and high-risk HCM.

Objective:To develop the Sexual Health Education Needs Assessment Scale for Breast Cancer Patients and test its reliability and validity.Methods:Guided by Maslow's hierarchy of needs theory and knowledge, belief, and practice theory, an initial scale was formed through literature review, semi-structured interviews and Delphi expert consultation. Through cognitive interviews with 9 patients, the scale was further revised and improved to form a clinical trial version. From December 2021 to September 2022, 397 breast cancer patients from 9 ClassⅢ hospitals in 6 provinces, municipalities and autonomous regions were selected by convenience sampling to conduct a questionnaire survey, test the reliability and validity of the scale and grade it.Results:The Sexual Health Education Needs Assessment Scale for Breast Cancer Patients included four dimensions and 32 items in total. Exploratory factor analysis extracted a total of four common factors, with a cumulative variance contribution rate of 72.258%. The content validity index of the scale was 0.865, and the content validity index of each item was 0.929 to 1.000. The correlation coefficients between each dimension of the scale and the total scale were 0.789 to 0.956, and the correlation coefficients between dimensions were 0.635 to 0.863. The Cronbach's α coefficient of the total scale was 0.979, and the Cronbach's α coefficients of each dimension were 0.897 to 0.969. The half reliability of the total scale was 0.941, and the half reliability of each dimension was 0.851 to 0.946. The total score of the scale was 32 to 160, with 32 to 77 being at a low level, 78 to 117 being at a medium level, and 118 to 160 being at a high level.Conclusions:The developed Sexual Health Education Needs Assessment Scale for Breast Cancer Patients has good reliability and validity, and is suitable for breast cancer patients' sexual health education needs assessment.

Objective : To explore the relationship between Porphyromonas gingivalis(Pg) and mitophagy in esopha- geal cancer cells，and to explore new therapeutic targets for esophageal cancer． Methods : ① Western blot was used to detect the phosphorylation of unc-51-like authophagy activating kinase1 (ULK1) in mitochondria of the Pg infected cells and immunohistochemical method was used to detect the correlation between the expression of Pg and the phosphorylation status of ULK1 in esophageal cancer tissues. ② Western blot，ICC and ELISA were used to de- tect the transfer of nucleotide blinding domain and leucine rich repeat containing family member X1 (NLRX1) from cytoplasm to mitochondria，mitophagy，and the secretion levels of interleukin ( IL) -6 and reactive oxygen species (ROS) under Pg infection. ③ Pg colonization in esophageal tissues of mice in each group was detected by qPCR and Pg colonization in esophageal squamous epithelial cells of mice by RNAscope. Results : Compared with the un- treated group，the phosphorylation level of mitochondrial ULK1 (P＜0．01) ，NLRX1 expression (P＜0. 001) and mitophagy (P＜0. 001) of esophageal cancer cells increased after Pg infection．Compared with the control group， the combined intervention group could inhibit Pg colonization in esophageal tissue and esophageal squamous epithe- lial cells of mice (P＜0. 001) ． Conclusion Pg promotes the translocation of NLRX1 from cytoplasm to mitochon- dria by up-regulating the phosphorylation level of ULK1 in the mitochondria of esophageal cancer cells，and then induces mitophagy，leading to the reduction secretion of IL-6 and ROS，and ultimately maintaining Pg colonization.

The antimicrobial peptide APKGVQGPNG (named YD), a natural peptide originating from Bacillus amyloliquefaciens CBSYD1, exhibited excellent antibacterial and antioxidant properties in vitro. These characteristics are closely related to inflammatory responses which is the central trigger for liver fibrosis. However, the therapeutic effects of YD against hepatic fibrosis and the underlying mechanisms are rarely studied. In this study, we show that YD improved liver function and inhibited the progression of liver fibrosis by measuring the serum transaminase activity and the expression of α-smooth muscle actin and collagen I in carbon tetrachloride-induced mice. Then we found that YD inhibited the level of miR-155, which plays an important role in inflammation and liver fibrosis. Bioinformatics analysis and luciferase reporter assay indicate that Casp12 is a new target of miR-155. We demonstrate that YD significantly decreases the contents of inflammatory cytokines and suppresses the NF-κB signaling pathway. Further studies show that transfection of the miR-155 mimic in RAW264.7 cells partially reversed the YD-mediated CASP12 upregulation, the downregulated levels of inflammatory cytokines, and the inactivation of the NF-κB pathways. Collectively, our study indicates that YD reduces inflammation through the miR-155–Casp12–NF-κB axis during liver fibrosis and provides a promising therapeutic candidate for hepatic fibrosis.
