Rapid and ultrasensitive detection of pathogen-associated biomarkers is vital for the early diagnosis and therapy of bacterial infections. Herein, we developed a close-packed and ordered Au@AgPt array coupled with a cascade triggering strategy for surface-enhanced Raman scattering (SERS) and colorimetric identification of the Staphylococcus aureus biomarker micrococcal nuclease (MNase) in serum samples. The trimetallic Au@AgPt nanozymes can catalyze the oxidation of 3,3',5,5'-tetramethylbenzidine (TMB) molecules to SERS-enhanced oxidized TMB (oxTMB), accompanied by the color change from colorless to blue. In the presence of S. aureus, the secreted MNase preferentially cut the nucleobase AT-rich regions of DNA sequences on magnetic beads (MBs) to release alkaline phosphatase (ALP), which subsequently mediated the oxTMB reduction for inducing the colorimetric/SERS signal fade away. Using this "on-to-off" triggering strategy, the target S. aureus can be recorded in a wide linear range with a limit of detection of 38 CFU/mL in the colorimetric mode and 6 CFU/mL in the SERS mode. Meanwhile, the MNase-mediated strategy characterized by high specificity and sensitivity successfully discriminated between patients with sepsis (n = 7) and healthy participants (n = 3), as well as monitored the prognostic progression of the disease (n = 2). Overall, benefiting from highly active and dense "hot spot" substrate, MNase-mediated cascade response strategy, and colorimetric/SERS dual-signal output, this methodology will offer a promising avenue for the early diagnosis of S. aureus infection.

The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

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
