Objective To explore the research status and future development trends of nursing case teaching at home and abroad,and to provide reference and guidance for the development of case teaching in nursing profession in China.Methods Data sources include the China National Knowledge Infrastructure(CNKI),Wanfang Data,and Web of Science databases.The CiteSpace software was used to visually analyze the research status and trends of nursing case teaching from January 2013 to Octo-ber 2023,covering nearly 11 years.Results A total of 2 889 valid articles were extracted.The important literature on nursing case teaching in China experienced a period of stable growth followed by rapid growth from 2013 to 2021.However,the number of publications and the number of publications in core journals on nursing case teaching abroad were higher than those in China.After 2021,both domestic and foreign publications on nursing case teaching showed a slow decline.The research on nursing case teaching in both domestic and foreign contexts is mainly conducted by universities,and the collaborative relationships between for-eign institutions and scholars are stronger than those within China.The research topics and hotspots in both domestic and foreign contexts are concentrated on the teaching applications for nursing students.Conclusion Nursing case teaching in China contin-ues to attract attention;however,compared to nursing case teaching abroad,the depth and breadth of research need to be further improved.Additionally,the collaboration between domestic authors and institutions is relatively limited.

In situ and real-time monitoring of responsive drug release is critical for the assessment of pharmacodynamics in chemotherapy. In this study, a novel pH-responsive nanosystem is proposed for real-time monitoring of drug release and chemo-phototherapy by surface-enhanced Raman spectroscopy (SERS). The Fe₃O₄@Au@Ag nanoparticles (NPs) deposited graphene oxide (GO) nanocomposites with a high SERS activity and stability are synthesized and labeled with a Raman reporter 4-mercaptophenylboronic acid (4-MPBA) to form SERS probes (GO-Fe₃O₄@Au@Ag-MPBA). Furthermore, doxorubicin (DOX) is attached to SERS probes through a pH-responsive linker boronic ester (GO-Fe₃O₄@Au@Ag-MPBA-DOX), accompanying the 4-MPBA signal change in SERS. After the entry into tumor, the breakage of boronic ester in the acidic environment gives rise to the release of DOX and the recovery of 4-MPBA SERS signal. Thus, the DOX dynamic release can be monitored by the real-time changes of 4-MPBA SERS spectra. Additionally, the strong T₂ magnetic resonance (MR) signal and NIR photothermal transduction efficiency of the nanocomposites make it available for MR imaging and photothermal therapy (PTT). Altogether, this GO-Fe₃O₄@Au@Ag-MPBA-DOX can simultaneously fulfill the synergistic combination of cancer cell targeting, pH-sensitive drug release, SERS-traceable detection and MR imaging, endowing it great potential for SERS/MR imaging-guided efficient chemo-phototherapy on cancer treatment.

Objective: To analyze the improvement of executive function in children with attention deficit hyperactivity disorder (ADHD) aged 7-14 years with comprehensive intervention and drug therapy alone, to provide a basis for intervention research to improve ADHD. Methods: A total of 80 children with ADHD treated in the Third People s Hospital of Ganzhou from January 2021 to June 2022 were randomly divided into intervention group and control group. The intervention group received drug and comprehensive intervention therapy, and sensory integration training once a week for 60 to 90 min each for 12 weeks, and conduct related training for caregivers and school teachers, the control group received only drug therapy. The changes of executive function were assessed by the stroop color word association test and the Wisconsin Card Sorting Test (WCST) after 12 weeks of intervention. Results: After intervention, the results of the Stroop color word test in the intervention group (3.25±0.98, 4.92±1.40, 10.17±1.28) showed statistically significant differences ( t=12.94, 15.36, 26.34 , P <0.01) compared with those before intervention (6.47±1.92, 8.35±1.25, 16.55±1.57). There were also statistically significant differences ( t=6.76, 15.01, 16.15, P <0.01) in the control group ( 3.95 ±1.01, 5.45±1.15, 12.35±0.86) compared to those before intervention (6.17±1.87, 8.10±1.03, 16.02±1.38). Before intervention, the number of perseverative errors, non perseverative errors, and completed categories by WCST in the intervention group were (47.77±4.50, 35.50±2.37, 3.97±1.07), and in the control group were (46.45±7.34, 34.87±2.29, 3.70±1.11). After intervention, those of the intervention group and control group were (31.42±2.01, 24.75±2.05, 5.05±1.13) and (32.82±2.57, 25.55±1.04, 4.25±1.48), respectively. There were significant differences in the two groups before and after intervention ( t =21.93, 22.27 , -10.37; 10.84, 26.81, -6.90, P <0.01). After intervention, there were significant differences in the number of Stroop color word test errors, perseverative errors and non perseverative errors in WCST between the two groups ( t=-2.94, 2.29, -9.07, -2.35 , -2.06, P <0.05). Conclusion Through training for children and the therapy model of comprehensive intervention could significantly improve the executive function of children for a certain extent.

Objective:To analyze the clinical and pathological features of adolescent- onset primary nephrotic syndrome (PNS) in children (10 years≤age≤18 years), so as to explore the renal biopsy indications in adolescent-onset PNS.Methods:It was a single-center retrospective observational study. The clinical and pathological data of adolescent-onset PNS (age≥10 years) who underwent renal biopsy in Children's Hospital Affiliated to Nanjing Medical University from December 2004 to June 2022 were analyzed retrospectively.Results:A total of 110 children were included in the study, including 76 males (69.1%) and 34 females (30.9%), with the onset age ranging from 10 years to 14 years and 9 months. Forty-nine cases (44.5%) were accompanied by hematuria, including 14 cases (12.7%) of gross hematuria and 35 cases (31.8%) of microscopic hematuria. Twenty-five cases (22.7%) had hypertension, 19 cases (17.3%) had renal insufficiency, and 4 cases (3.6%) had low complement C3 at the onset. Fifty-two cases (47.3%) were steroid sensitive nephrotic syndrome and 58 cases (52.7%) were steroid resistant nephrotic syndrome. Biopsy results showed that minimal change disease(MCD) was the most common histopathological subtype (47.3%, 52 case), followed by focal segmental glomerulosclerosis (FSGS) in 22 cases (20.0%), IgA nephropathy (IgAN) in 17 cases (15.5%), membranous nephropathy (MN) in 7 cases (6.4%), mesangial proliferative glomerulonephritis in 5 cases (4.5%), IgM nephropathy in 4 cases (3.6%), membranous proliferative glomerulonephritis in 2 cases (1.8%), and C1q nephropathy in 1 case (0.9%). Among 44 children with simple type nephrotic syndrome, the pathological type was mainly MCD (77.3%), and 66 children with nephritic type nephrotic syndrome were mostly non-MCD (72.7%), such as IgAN, FSGS, MN, etc. If there are two or more clinical manifestations of persistent hematuria, hypertension, renal insufficiency or low C3 levels, the proportion of non-MCD would further increase to 92.0%(23/25). The pathological type of patient with gross hematuria or low C3-emia was non-MCD. The frequency of hematuria (69.0% vs. 17.3%, χ2=29.619, P<0.001), hypertension (31.0% vs. 13.5%, χ2=4.821, P=0.028) and renal insufficiency (24.1% vs. 9.6%, χ2=4.047, P=0.044) in non-MCD group was significantly higher than those in MCD group. Conclusions:If the clinical manifestation of PNS in adolescent over 10 years old is simple type nephrotic syndrome, the histopathological lesion is mostly MCD, and most of them are steroid sensitive. It is recommended to give hormone treatment first, and then perform renal biopsy if steroid resistance occurs; If the clinical manifestation is nephritic type nephrotic syndrome, the histopathological lesion is mostly non-MCD, especially those with gross hematuria or low C3-emia, or those have two or more clinical manifestations of persistent hematuria, hypertension, renal insufficiency and hypocomplement C3-emia, a kidney biopsy should be performed at onset.

Objective: To analysis gender disparities in epidemiological trend of HIV/AIDS disease burden among Chinese population aged 10-24 years from 1990 to 2019. Methods: The Global Burden of Disease Study (GBD 2019) results tool was used to extract the number of deaths, mortality rate, disability adjusted life years (DALY), DALY rate, years of life lost (YLL), YLL rate, years lived with disability (YLD) and YLD rate to comprehensively analyze the change range of HIV/AIDS disease burden in the Chinese population aged 10-24 years from 1990 to 2019. Results: In 2019, the number of deaths, mortality rate, DALY, DALY rate, YLL, YLL rate, YLD and YLD rate of Chinese population aged 10-24 years due to HIV/AIDS were 847, 0.37 per 100 000 , 62 621 person years, 27.51 per 100 000, 58 036 person years, 25.49 per 100 000, 4 584 person years, 2.01 per 100 000 respectively, with the increase of 401.18%, 691.49%, 370.48%, 648.26%, 409.53%, 710.33%, 138.87% and 279.25% , compared with the data in 1990. In term of gender, the number of deaths, mortality rate, DALY, and DALY rate of Chinese male population aged 10-14, 15-19 and 20-24 years due to HIV/AIDS in 2019 were higher than those of female, and the growth rate (compared with 1990) was also higher than that of female. In term of the age group, the increase in people aged 10-14 years was higher than that of people aged 20-24 years. From 1990 to 2019, with the increase of year and age, gender disparity between mortality and DALY rate widened. Conclusion Compared with data in 1990, the risk of HIV/AIDS infection in 2019 among Chinese population aged 10-24 years continued to increase, especially among young people of 10-14 years. Gender disparity is exacerbating.

Objective:To investigate the clinical manifestations, pathological characteristics, treatment and prognosis of anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) in 13 children.Methods:The clinical and pathological data of 13 cases of AAV in children′s Hospital of Nanjing Medical University from June 2000 to December 2021 were retrospectively analyzed.Results:Among the 13 cases, 12 cases were diagnosed with microscopic polyangiitis (MPA) and 1 case was granulomatosis with polyangiitis (GPA), including 10 females and 3 males. The onset age ranged from 3 years and 11 months to 13 years and 10 months. The most frequently involved organ was the kidney (12 cases, 92.3%), followed by respiratory system (7 cases, 53.8%), skin (5 cases, 38.5%), digestive system (4 cases, 30.8%), nervous system (4 cases, 30.8%) and cardiovascular system (3 cases, 23.1%). There were 10 cases with orthotic anemia, 7 cases with positive antinuclear antibody, and 3 cases with mildly decreased complement C3. Among the 12 children with renal impairment, 9 cases were accompanied by abnormal renal function at the beginning of the disease. Renal biopsy was classified according to the Berden as follows: sclerotic in 5 cases, crescentic 3 cases, focal in 2 cases and mixed in 2 cases. All children were treated with glucocorticoid combined with immunosuppressant. During the follow-up time from 8 months to 128 months, 4 cases acquired complete remission, 8 cases achieved partial remission and 1 case recurred after complete remission, and 7 cases progressed to chronic kidney disease stage 5. Three children with complete remission underwent repeated renal biopsy, including 2 cases of mixed type and 1 case of crescent type initially, and all changed to focal type.Conclusions:AAV in children occurs mainly in school-age female, and most of AAV in children is MPA. The clinical manifestations are various. Most of them have renal damage and anemia, and lung damage is also common. Patients with skin purpura onset may be misdiagnosed as Henoch-Schonlein purpura, and AAV with ANA positive or complement reduction should exclude systemic lupus erythematosus. Once the renal function is abnormal in AAV, especially estimated glomerular filtration rate<60 ml·min -1·(1.73 m 2) -1 and the pathological classification is sclerotic type or crescent type, it is difficult to reverse even after active treatment. Early diagnosis and treatment are very important for AAV.

Solid tumors always exhibit local hypoxia, resulting in the high metastasis and inertness to chemotherapy. Reconstruction of hypoxic tumor microenvironment (TME) is considered a potential therapy compared to directly killing tumor cells. However, the insufficient oxygen delivery to deep tumor and the confronting "Warburg effect" compromise the efficacy of hypoxia alleviation. Herein, we construct a cascade enzyme-powered nanomotor (NM-si), which can simultaneously provide sufficient oxygen in deep tumor and inhibit the aerobic glycolysis to potentiate anti-metastasis in chemotherapy. Catalase (Cat) and glucose oxidase (GOx) are co-adsorbed on our previously reported CAuNCs@HA to form self-propelled nanomotor (NM), with hexokinase-2 (HK-2) siRNA further condensed (NM-si). The persistent production of oxygen bubbles from the cascade enzymatic reaction propels NM-si to move forward autonomously and in a controllable direction along H

Objective:To explore the value of radiographic assessment of lung edema (RALE) score in evaluating the severity and prognosis of patients with acute respiratory distress syndrome (ARDS).Methods:A retrospective study was conducted. Patients with ARDS admitted to the department of intensive care unit (ICU) of Affiliated Nantong Third Hospital of Nantong University from January 2016 to November 2020 were enrolled. Clinical data of those patients were collected, and two senior radiologists who did not know the outcome of the patients independently scored each chest radiograph, the mean value of which was taken as the RALE score. The patients were divided into death group and survival group according to the 28-day prognosis. The differences of the basic data, PaO 2/FiO 2, sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score and RALE score between groups were analyzed. ARDS patients were classified according to the Berlin standard and RALE scores were compared between groups. Then, the correlations between RALE score and PaO 2/FiO 2, SOFA score, APACHEⅡ score were analyzed. The prognostic capacity of RALE score for 28-day prognosis of ARDS patients were analyzed by Kaplan-Meier survival curve. Results:Of the 98 ARDS patients, 62 were included in the final analysis, 39 patients survived and 23 patients died. The 28-day mortality was 37.1%. Compared with the survival group, patients in the death group were older (years old: 72.83±12.21 vs. 64.44±14.68), had lower PaO 2/FiO 2 [mmHg (1 mmHg = 0.133 kPa): 122.66±48.32 vs. 150.26±50.40], and higher SOFA score and greater difference of RALE score between the third day and the first day after admission (D3-D1 RALE score) (SOFA score: 11.26±3.91 vs. 9.04±3.72, D3-D1 RALE score: 1.35±6.42 vs. -2.74±7.35), with statistically significant differences (all P < 0.05). However, there were no significant differences in gender, cause of ARDS, APACHEⅡ score, and RALE scores on the first and the third day of admission (D1 RALE, D3 RALE) between the two groups. Among the 62 patients, there were 11 mild cases (17.7%), 36 moderate cases (58.1%), and 15 severe cases (24.2%). The D1 RALE score of patients with mild and moderate ARDS were lower than those of patients with severe ARDS (19.09±3.65, 22.58±6.79 vs. 27.07±5.23, both P < 0.05). Correlation analysis showed that D1 RALE score was negatively correlated with PaO 2/FiO 2 ( r = -0.385, P = 0.002), and positively correlated with SOFA score and APACHEⅡ score ( r1 = 0.433, r2 = 0.442, both P < 0.001). Kaplan-Meier survival curve analysis showed that the 28-day survival rate of ARDS patients in D3-D1 RALE score ≥ -1 group was significantly higher than that in D3-D1 RALE score < -1 group (73.08% vs. 55.56%; log-rank test: χ 2 = 3.979, P = 0.046). Conclusions:The RALE score is a simple and reliable non-invasive evaluation index, which can be used to evaluate the severity of ARDS patients. The difference of RALE score in early stage is helpful to identify ARDS patients with poor prognosis.

Objective:To investigate the effect of rapamycin on hepatic ischemia-reperfusion injury (HIRI) in Sprague Dawley (SD) rats and its underlying mechanism.Methods:Forty-eight specific pathogen-free SD male rats with the body weight of 180-200 g and the age of 4-8 weeks were randomly divided into 3 groups, 16 rats each group. In the rapamycin group, the rats were injected with rapamycin intraperitoneally everyday lasting for 3 days before the surgery, and in the model group and the sham group, the rats were injected with normal saline intraperitoneally. The HIRI model was performed in the rapamycin group and the model group. Serum of 8 rats was randomly harvested from each group at 2 h and 24 h after the surgery and was used to detect level of alanine aminotransferase(ALT), total bilirubin, and lactate dehydrogenase. At the meantime, liver tissues were collected for HE staining, and enzyme-linked immunosorbent assay of superoxide dismutase(SOD), glutathione, hexokinase 2, phosphofructokinase 1(PFK1), and adenosine triphosphate. Polymerase chain reaction and Western blots were used to determine the levels of mammalian target of rapamycin(mTOR), ribosomal protein S6 kinase 1(S6K1), and protein kinase B and their phosphorylation levels respectively.Results:Two hours post the surgery, the serum level of ALT(150.9±18.7) U/L, total bilirubin(5.15±0.69) μmol/L, and lactate dehydrogenase(9 547±365) U/L were higher in the model group than sham group (42.4±10.7) U/L, (2.48±0.24) μmol/L, (4 424±376) U/L and rapamycin group (87.7±11.2) U/L, (3.09±0.12) μmol/L, (8 268±264) U/L, and all differences were statistically significant (all P<0.05). HE staining and serum assay showed that the lesion of liver tissuesand of liver function were damaged in the model group, and mitigated in the rapamycin group at 2h and 24h after the surgery. At 2h and 24h after the surgery, liver SOD, glutathione, hexokinase 2, PFK1, and adenosine triphosphate in the model group were lower than those in the sham group and the rapamycin group, and all differences were statistically significant (all P<0.05). The relative levels of mTOR, S6K1, and their phosphorylation level in the model group were higher than those in the sham group and the rapamycin group at 2 h and 24 h after the surgery, but the relative levels of protein kinase B and phosphorylated protein kinase B were lower than those in the sham group and the rapamycin group, and all differences were statistically significant (all P<0.05). Conclusions:Rapamycin improves glucose metabolism and reduces oxidative stress via upregulating the phosphorylated protein kinase B through inhibition of mTOR signaling pathway, thus alleviates HIRI in rats.
