Objective To investigate the level and influencing factors of subjective well-being of nurses and establish a model of the relationship of job stress, self-efficacy and subjective well-being. Methods Totally 438 nurses from 5 hospitals in Changchun city were investigated with the self-designed demographic questionnaire, General Well-Being Scale, Nurse Job Stressors Scale and Self-Efficacy Scale. Results The total score of subjective well-being was (71.36 ± 18.83) points. Single factor analysis found that age (F=1.759, P<0.01), department (F=1.712, P<0.01), professional title (F=1.364, P<0.05), years of working (F=1.420, P<0.05) and monthly income (F=1.632, P<0.01) were statistically significant. Multiple linear regression analysis showed that sex (t=-2.447, P<0.05), the first factor of job stress (t=-5.033, P<0.01), the second factor (t=-2.478, P<0.05), the third factor (t=-2.315, P<0.05), the fifth factor (t=-5.862, P<0.01) and self-efficacy (t=10.705, P<0.01) were the predictive effectton of subjective well-being. The result of path analysis shows that self-efficacy has a significant effect of adjustment on job stress and subjective well-being (direct effects=-0.62, indirect effects=-0.24, P<0.01). Conclusions The nurse subjective well-being is in the medium level. Hospitals and all related departments should take effective measures to reduce or eliminate unfavorable factors and increase the protective factors, and then improve the level of nurses′subjective well-being and nursing quality.

Tertiary lymphoid structure (TLS) is the ectopic lymphoid tissue around the chronic inflammatory site of tumor, infection diseases, autoimmunity diseases, organ transplantation and so on. TLS is regarded as the vital niche of antitumor immune response in tumor microenvironment for abundant immune cells, and is correlated with better clinical outcomes and immunotherapy response in most solid tumors. As a typical inflammation-driven cancer, hepatocellular carcinoma (HCC) is controversial with the influence of TLS on patients prognosis. In this paper, the composition, formation mechanism, recognition and clinical value of TLS in HCC were briefly reviewed.

Objective:To explore the research progress and hotspots of nurse-led care models in China, in order to provide references for further research.Methods:The Papers related to nurse-led care models included before 2019 were retrieved from Wanfang database and based on core nursing periodicals from Chinese S&T Journal Citation Reports(Natural Science)(2018 edition), used Bicomb2.0 for word frequency analysis of key words, then used SPSS22.0 for clustering analysis.Results:Totally 118 references and 33 high frequency keywords were retrieved. The number of literature about nurse-led showed a fluctuating upward trend. Researchers could get most of the information about nurse-led intervention mode from Journal of Nursing Science, Chinese Nursing Research and Chinese Nursing Management. By cluster analysis, the hotspots of nurse-led mainly involved critical illness, tumor, chronic disease, community rehabilitation and so on. Conclusions:The nurse-led model has been used in many kinds of diseases and has formed a certain scale, but there is still more room for development. Nursing experts from different regions should strengthen cooperation to improve the nurse-led intervention mode.

Objective To investigate the effect and mechanism of Qianggu Tongbi capsule on osteoarthritis factors in rats.Methods Osteoarthritis(OA)rat model was established by anterior cruciate ligament transection method.Rats were ran-domly divided into model group,Qianggu Tongbi capsule group and glucosamine group.HE staining was used to identify the model.Toluidine blue staining was used to observe the changes of cartilage.Real-time quantitative polymerase chain reaction(qRT-PCR)was applied to detect the expression of Toll-like receptors(TLR4)and nuclear factor kappa-B(NF-κB)in each group.The levels of IL-1β,TNF-α,and IL-6 were measured by the enzyme linked immunosorbent assay(ELISA)kit.The levels of TLR4 and p-NF-κB were detected by immunohistochemistry.Results HE staining showed that,compared with the control group,a large number of inflammatory cell infiltration and synovial tissue thickening were observed in the model group,while the inflammatory cell infiltration and synovial tissue thickening were not obvious in the Qianggu Tongbi capsule and glu-cosamine groups.Toluidine blue staining results showed that chondroitin sulfate in the cartilage tissue of the model group was significantly reduced compared with the control group,while levels of chondroitin sulfate in the Qianggu Tongbi capsule group and glucosamine group were significantly increased.Compared with control group,the expression and immunohistochemical re-sults of TLR4 and NF-κB,and the levels of IL-1β,TNF-α and IL-6 in model group were significantly increased(all P＜0.05).Compared with model group,the expression and immunohistochemical results of TLR4 and NF-KB,and the levels of IL-1β,TNF-α and IL-6 in Qianggu Tongbi capsule group and glucosamine group were significantly decreased(all P＜0.05).Conclusion Qianggu Tongbi capsule can inhibit expression of TLR4 and NF-κB by reducing the production of inflammatory factors to a-chieve the effect of treatmenting osteoarthritis.

Objective To screen and analyze the influencing factors of severity in the patients with type 2 diabetes mellitus (T2DM) complicating cerebral small vessel disease (CSVD).Methods A total of 519 pa-tients with T2DM complicating CSVD admitted and treated in Nanjing Municipal Hospital of Traditional Chi-nese Medicine from June 2018 to May 2023 were selected and divided into the mild group (n=214) and the se-vere group (n=305) according to the CSVD imageological score.The relevant demographic,laboratory and imageological indicators were collected.The influencing factors of T2DM complicating CSVD were screened out by the LASSO and Logistic regression analysis and the predictive model was established.The receiver op-erating characteristic (ROC) curve,goodness of fit evaluation and restricted cubic spline (RCS) fitting curve were drawn to analyze the dose-response relationship between Cys C,albumin/globulin (A/G) ratio with the disease severity.Results The male proportion and age in the severe group were greater than those in the mild group,neutrophil,systemic immune-inflammation index (SII),creatinine (Crea),uric acid (UA),Urea (Ure-a),D-dimer (D-D),lactate dehydrogenase (LDH),adenosine deaminase (ADA),globulin (GLB) and Cys C were higher than those in the mild group,lymphocyte,ALT,High density Lipoprotein-cholesterol (HDL-C),serum cholinesterase (CHE),prealbumin (PAB),and A/G were lower than those in the mild group,and the differences were statistically significant (P<0.05).LASSO and logistic regression analysis showed that the gender,age,A/G and Cys C were the independent influencing factors in the patients with T2DM complicating CSVD.The area under the curve (AUC) of this model was 0.658 (95%CI:0.610-0.706) with goodness of fit (P=0.520).The RCS fitting curves showed that serum Cys C≥0.618 mg/L had a linear relationship with CSVD imageological score (P=0.035),and A/G≥1.268 had a nonlinear relationship with CSVD imageologi-cal score (P=0.007).Conclusion The advanced age,male,increased Cys C level and decreased A/G in the pa-tients with T2DM complicating CSVD are the independent risk factors for the severity of whole brain damage.

Objective To screen the characteristic factors of renal impairment occurrence in the patients with hyperuricemia,and to analyze its diagnostic value and establish a diagnostic model.Methods A total of 2405 inpatients with diagnosed hyperuricemia in the Nanjing Municipal Hospital of Traditional Chinese Medi-cine,Nanjing University of Traditional Chinese Medicine from December 2018 to December 2022 were selected and divided into the kidney lesion group (n=1343) and the non-kidney lesion group (n=1062) according to eGFR.The characteristic factors of hyperuricemia caused renal impairment were screened and analyzed by Lasso and logistic regression and the diagnostic model was constructed.The diagnostic value of characteristic factors and diagnostic model were evaluated by the receiver operating characteristic (ROC) curve,and the change rule between the characteristic factors and the results was found by the restricted cubic splines (RCS) fitting.Results The age,uric acid (UA),cystatin-C (Cys-C) and retinol-binding protein (RBP) were the characteristic factors of hyperuricemia caused renal impairment.The combined diagnostic model:logit (P)=-8.70+0.602×age (10 years old)+0.033×UA (10 μmol/L)+0.277×Cys-C (0.1 mg/L)+0.189×RBP (10 mg/L),the area under the ROC curve (AUC) of the combined diagnosis model was 0.893 (95％CI:0.880-0.905).For every 10 μmol/L increase in blood UA,the risk of renal impairment occurrence in hyperurice-mia was increased by 3％;for every 10 years increase in age,the risk of renal impairment occurrence in hyperu-ricemia was increased by 83％;for every 10 mg/L increase in RBP,the risk of kidney damage occurrence of re-nal impairment in hyperuricemia was increased by 21％;for every 0.1 mg/L increase in Cys-C,the risk of re-nal impairment occurrence in hyperuricemia was increased by 32％.Conclusion The combined diagnostic model for whether the renal impairment in the patients with hyperuricemia occurring has good diagnostic val-ue,and Cys-C deserves more attention.

Objective:To explore the differences in bacterial community structure between proximal colon cancer (PC), distal colon cancer (DC), and rectal cancer (RC), and the values of featured microbiota in differentiating PC with tumor markers.Methods:This case-control study enrolled 85 newly diagnosed colorectal cancer patients, including 22 PC, 15 DC and 48 RC patients, and 8 colorectal adenoma patients from May 2019 to July 2022 at the Department of General Surgery, Anyang Oncology Hospital. The blood and fecal samples were collected before surgery and then subjected to biochemical tests for tumor markers and 16S rDNA tests, respectively. SPSS (27.0.1) was applied to perform the t-test, one-way ANOVA, Mann-Whitney U test, Kruskal-Wallis H test, and Chi-Squared Test. Also, the receiver operating characteristic curve (ROC) was plotted on tumor markers and/or f_Bacteroidaceae with SPSS software .Results:All groups had significant differences in the CA125 ( F=3.543, P<0.05), CA72-4 ( F=3.596, P<0.05), and serum tumor-associated materials (TAM) levels ( F=5.787, P<0.01). In PC group, the levels of CA125 [PC vs RC, (36.84±6.30) kU/L vs (12.73±4.21) kU/L, P<0.01] and CA72-4 [PC vs RC, (45.56±10.86) kU/L vs (3.30±7.63) kU/L, P<0.01] were significantly higher than that of the RC group, while the level of TAM was remarkably elevated in PC group than in RC group [PC vs RC, (124.84±5.19) U/ml vs (102.44±3.63) U/ml, P<0.001] and CRA group [PC vs CRA, (124.84±5.19) U/ml vs (95.39±8.42) U/ml, P<0.01]. The LEfSe analysis showed that the featured microbiota in the PC group included f_Bacteroidaceae, f_Neisseriaceae, f_Clostridiaceae_1, f_Spirochaetaceae, and so on. The largest area under the ROC belonged to the combination of TAM and f_Bacteroidaceae, which reached 0.845 (95% CI 0.747-0.944), with sensitivity being 0.857 and specificity being 0.815. Conclusions:There is heterogeneity in gut microbiota composition among PC, DC, RC, and CRA. The combination of gut microbiota and tumor biomarkers demonstrated good differentiating effects in proximal colon cancers.

Objective:To investigate the short- and long-term outcomes of fetuses with selective fetal growth restriction (sFGR).Methods:A retrospective study was conducted on monochorionic diamniotic (MCDA) twins with sFGR admitted to the Neonatal Intensive Care Unit of Peking University Third Hospital from September 2017 to December 2019. MCDA neonates delivered during the same period without significant complications were selected as the control group. MCDA twins with sFGR were divided into type Ⅰ, Ⅱ, and Ⅲ groups and then further divided into the larger and the smaller fetus subgroups according to the birth weight. These children were followed up by telephone at 2-3 years old. Height-for-age and weight-for-age Z-scores were calculated. Ages and Stages Questionnaire-Third Edition (ASQ-3) was used to determine comprehensive development. Independent sample t-test, one-way analysis of variance, non-parameter test, and Chi-square test (or rank-sum test) were used for statistical analysis. Results:(1) A total of 116 pregnant women with sFGR (232 neonates) were enrolled in this study. There were 43, 40, and 33 mothers and 86, 80, and 66 newborns in type Ⅰ, Ⅱ, and Ⅲ groups, respectively. The control group included 31 pregnant women and 62 neonates. The gestational age at onset of sFGR was younger in the type Ⅱ and Ⅲ groups than in type Ⅰ group [(23.8±4.8) and (24.1±3.1) vs (27.0±6.1) weeks, F=5.19, P<0.05; all P<0.017 during pairwise comparisons]. (2) The incidence of sepsis and treatment abandonment/death in neonates in type Ⅱ and Ⅲ groups were higher than those in type Ⅰ and control groups [neonatal sepsis: 11.3% (9/80) and 6.1% (4/66) vs 2.3% (2/86) and 0.0% (0/62), χ2=6.30, P=0.001; death or treatment abandonment rate:13.8% (11/80) and 10.6% (7/66) vs 3.5% (3/86) and 0.0% (0/62), χ2=4.68, P=0.003; all P<0.017 during pairwise comparisons]. In cases with type Ⅱ or type Ⅲ sFGR, the risk of digestive system diseases was significantly higher in the smaller fetus group than in the larger fetus group [type Ⅱ: 46.2% (37/80) vs 38.7% (31/80), χ2=16.72; type Ⅲ: 47.0% (31/66) vs 34.8% (23/66), χ2=39.69; both P<0.001], while the rate of respiratory system diseases was lower in the smaller fetus group [type Ⅱ: 35.0% (28/80) vs 45.0% (36/80), χ2=36.85; type Ⅲ: 37.9% (25/66) vs 45.4% (30/66), χ2=12.55; both P<0.001]. The incidence of neonatal sepsis in smaller fetuses was higher than that in larger ones in type Ⅱ sFGR [7.5% (6/80) vs 3.7% (3/80), χ2=4.68, P=0.034]. The incidence of neurological complications in larger fetuses was higher than that in smaller ones in type Ⅲ sFGR [15.1% (10/66) vs 4.5% (3/66), χ2=5.72, P<0.001]. (3) In type Ⅱ group, seven neonates died (one case of cerebral hemorrhage, two cases of gastrointestinal perforation, two cases of septic shock, and two cases of necrotizing enterocolitis), and four cases withdrew the treatment. In type Ⅲ group, four neonates died (two cases of necrotizing enterocolitis, one case of gastrointestinal perforation, and one case of cerebral hemorrhage), and three cases withdrew from the treatment. (4) Totally, 71 children in type Ⅰ, 61 in type Ⅱ, and 58 in type Ⅲ group were followed up at the age of 2-3. Children with type Ⅱ or type Ⅲ sFGR lagged behind those in type Ⅰ group and control group in physical growth [ M ( P25- P75), Z-scores:－0.46 (－0.87-0.42),－0.35 (－0.62-0.71), 0.05 (－0.61-0.51), and 0.14 (－0.57-0.75); H=6.20, P=0.001]. In type Ⅱ and Ⅲ groups, the smaller fetuses lagged the larger fetuses in physical growth at 2-3 years of age. ASQ-3 scores in communication, gross motor, fine motor, problem-solving and personal-social areas were all lower in type Ⅱ and Ⅲ groups than in type Ⅰ and control groups. ASQ-3 scores in the five dimensions of the smaller fetuses in the type Ⅱ group were lower than those of the larger fetuses. In the type Ⅲ group, the smaller fetuses had lower ASQ-3 scores in communication and gross motor than the larger ones [communication ability: (42.6±18.8) vs (56.4±9.4) scores, t=19.63, P<0.001; gross motor: (45.5±19.7) vs (54.5±9.7) scores, t=12.64, P=0.003]. Conclusion:The neonatal morbidity is significantly increased in type Ⅱ and Ⅲ sFGR, and babies lagged others in height, weight, and ASQ-3 score at 2-3, which is worthy of early attention.
