Objective To investigate and analyze the relationship between bone metabolism indicators,bone mineral density(BMD)T value,osteoporosis and fracture risk in patients with type 2 diabetes mellitus(T2DM).Methods A retrospective analysis was conducted on the clinical data of 175 patients with T2DM ad-mitted to the hospital from January to August 2024.According to the T value,they were divided into the oste-oporosis group(n=65),the osteopenia group(n=50),and the normal bone mass group(n=60).The general clinical data and bone metabolism indicators were compared among the three groups,including 25-hydroxyvi-tamin D3[25-(OH)D3],osteocalcin(OC),calcitonin(CT),type Ⅰ procollagen amino-terminal peptide(PⅠNP)and β-collagen degradation products(β-CTX),parathyroid hormone(PTH),T value,and the differences between the fracture risk assessment tools[FRAX,including 10-year major osteoporotic fracture(MOF)risk and 10-year hip fracture(HF)risk],analyzed the influencing factors of osteoporosis in T2DM patients,as well as the relationship between bone metabolism indicators,T values and fracture risk.Results The results of un-ivariate and multivariate logistic regression analyses showed that PⅠNP and β-CTX were risk factors for oste-oporosis in patients with T2DM,while estradiol(E2),testosterone(T),25-(OH)D3,OC,and T values were all protective factors(P<0.05).The 10-year risks of MOF and HF in the osteoporosis group were higher than those in the osteopenia group and the normal bone mass group,while the 10-year risks of MOF and HF in the osteopenia group were higher than those in the normal bone mass group,the differences were statistical-ly significant(P<0.05).According to Pearson correlation analysis,25-(OH)D3 and T values were negatively correlated with the risks of 10-year MOF and HF,while OC,PⅠNP,and β-CTx were positively correlated with the risks of 10-year MOF and HF(P<0.05),CT and PTH were not correlated with the risks of 10-year MOF and HF(P>0.05).Conclusion Bone metabolism indicators and BMD are important influencing factors for the occurrence of osteoporosis in patients with T2DM,and they are closely related to the occurrence of os-teoporotic fractures.Clinically,the monitoring of bone metabolism and BMD in patients with T2DM should be strengthened.

Objective:To explore the key factors affecting health-related quality of life in children with brain tumors following initial diagnosis and to analyze its impact on survival and prognosis.Methods:Seventy-eight pediatric brain tumor patients who participated in a prospective cohort study between June 1st，2016 and June 30th，2021 were included for health-related quality of life assessment and long-term follow-up（median follow-up duration：52 months）.Results:The male-to-female ratio among the 78 children was 1.1：1，with a median age of 7.0（4.0，10.0）years. The scores of the Pediatric Quality of Life Inventory? 4.0 Generic Core Scales（PedsQL? 4.0）were（67.40±18.26）for parent proxy reports and（67.87±20.40）for child self-reports. Cronbach's α coefficients ranged from 0.790 to 0.927，with the intraclass correlation coefficient（ICC）was 0.673. According to the PedsQL? 4.0，impaired quality of life was observed in 50.0% of children by parent proxy report and 52.8% by child self-report，primarily affecting physical and role functioning. In addition，70% of caregivers reported impaired quality of life，with worry being the most prominent issue. Key factors affecting children's quality of life included radiotherapy，tumor stage，annual family income，and parents' marital status，while caregivers' quality of life was influenced by radiotherapy and the child's IgA levels（all P<0.05）. Children with decreased total scores，impaired physical functioning，or impaired emotional functioning on the PedsQL? 4.0 parent proxy report exhibited an increased risk of mortality（all P<0.05）. In multivariate Cox regression analysis，independent prognostic factors included a decrease in the total score on the PedsQL? 4.0 parent proxy report（ HR=6.702，95% CI：1.442-31.151， P<0.05），presence of hydrocephalus（ HR=33.602，95% CI：4.354-259.333， P<0.05），tumor recurrence（ HR=16.846，95% CI：3.158-89.852， P<0.05），and absence of hydrocephalus shunt surgery（ HR=13.428，95% CI：1.761-102.394， P<0.05）. Conclusion:The quality of life of newly diagnosed children with brain tumors is lower than that of healthy children，and quality of life is an important prognostic factor. Quality of life assessment should be an integral component of a comprehensive management program for children with brain tumors.

Objective:To analyze the clinical characteristics, treatment methods, and efficacy of hemorrhagic supratentorial deep brain arteriovenous malformation(BAVM) in children.Methods:Clinical data of 12 pediatric patients with hemorrhagic supratentorial deep BAVM diagnosed and treated in the Department of Neurosurgery, Children′s Hospital of Nanjing Medical University from May 2020 to January 2023 were retrospectively analyzed.Among them, there were 7 males and 5 females, aged range from 4.8 to 14.1(9.6±3.2) years old.On the day of onset, the children underwent lateral external ventricular drainage, combined surgery, evacuation of intracranial hematoma, or medication to reduce intracranial pressure, based on the location of intracranial hemorrhage, degree of neurological dysfunction, and angioarchitecture of BAVM.Afterwards, the patients were given embolization with stable physical signs.The data of 12 patients were analyzed retrospectively, including clinical manifestations, imaging features, and treatment outcomes.Results:All 12 children started with intracranial hemorrhage.Digital subtraction angiography confirmed the diagnosis of deep BAVM, with 6 cases having the niduses in the splenium of the corpus callosum, 3 cases in the body of the corpus callosum, 2 cases in the basal ganglia area, and 1 case in the thalamus.Ten children had an intracranial hemorrhage in the lateral ventricle.Among them, 6 children underwent lateral external ventricular drainage on the day of onset and then were given BAVM embolization 7-14 days after onset; 1 patient experienced intraoperative bleeding, but showed no neurological dysfunction after surgery; 1 patient experienced temporary facial numbness; 1 patient with massive hemorrhages in the occipital lobe and lateral ventricle underwent combined surgery to embolize the BAVM and remove intracranial hematoma on the first day of onset; 1 patient suffered from basal ganglia hemorrhage with lateral intraventricular hemorrhage, and evacuation of intracranial hematoma was performed on the day of onset, and BAVM embolization was performed 7 days after surgery.Three months after combined surgery and embolization and 3 years after gamma knife treatment, the digital subtraction angiography was re-performed, and results showed that 5 cases, including 1 child undergoing combined surgery, was cured through a single interventional embolization, and 1 case was cured by a single embolization combined with gamma knife treatment.Conclusions:Intracranial hemorrhage caused by deep BAVM in children is mainly located in the lateral ventricle.In the acute phase, the main focus is on treating intracranial hypertension caused by obstructive hydrocephalus and intracranial parenchymal hematoma.Interventional embolization is safe and effective in the treatment of deep BAVM in children.

Rheumatoid arthritis (RA) is a prevalent autoimmune disease characterized by chronic inflammation and excessive proliferation of the synovium. Currently, treatment options focus on either reducing inflammation or inhibiting synovial hyperplasia. However, these modalities are unsatisfactory in achieving the desired therapeutic outcomes. Halofuginone hydrobromide (HF), an herbal active ingredient, has demonstrated pharmacological effects of both anti-inflammation and inhibition of synovial hyperplasia proliferation. However, HF's medical efficacy is limited due to its poor water solubility, short half-life (t _1/2), and non-target toxicity. In the current study, by using the advantages of nanotechnology, we presented a novel dual-targeted nanocomplex, termed HA-M@P@HF NPs, which consisted of a hyaluronic acid (HA)-modified hybrid membrane (M)-camouflaged poly lactic-co-glycolic acid (PLGA) nanosystem for HF delivery. These nanocomplexes not only overcame the limitations of HF but also achieved simultaneous targeting of inflammatory macrophages and human fibroblast-like synoviocytes-RA (HFLS-RA). In vivo experiments demonstrated that these nanocomplexes effectively suppressed immune-mediated inflammation and synovial hyperplasia, safeguarding against bone destruction in rats with adjuvant-induced arthritis (AIA). Remarkable anti-arthritic effects of these nanocomplexes were accomplished through promoting repolarization of M1-to-M2 macrophages and apoptosis of HFLS-RA, thereby offering a promising therapeutic strategy for RA.

Objective : To investigate the awareness of nutritional health knowledge regular unpaid blood donors in Zhoushan City, Zhejiang Province, so as to provide insights into nutrition and health education among unpaid blood donors. Methods: The regular unpaid blood donors were sampled using a convenient sampling method from Zhoushan Central Blood Station from January 1, 2021 to June 30, 2022. The nutritional health knowledge was investigated using the Chinese Nutrition Health Knowledge Questionnaire for Adults compiled by Chinese Center for Disease Control and Prevention, and the awareness and source of nutritional health knowledge was descriptively analyzed. Results: Totally 526 questionnaires were allocated, and 502 valid questionnaires were recovered, with an effective recovery rate of 95.44%. The respondents included 240 men (47.81%) and 262 women (52.19%), and included 343 individuals at ages of 18 to 44 years (68.33%), and 159 individuals at ages of 45 years and older (31.67%). The overall awareness of nutritional health knowledge was 14.54% among regular unpaid blood donors in Zhoushan City, and a higher awareness was seen among female regular unpaid blood donors (17.56%) than among males (11.25%) (P<0.05), while the awareness of nutritional health knowledge was significantly higher among respondents at ages of 18 to 44 years than among those at ages of 45 years and older (16.91% vs. 9.43%, P<0.05). The awareness of nutritional health knowledge was significantly higher among respondents with an educational level of junior college and above than among those with an educational level of high school/technical secondary school/technical school (17.24% vs. 12.22%, P<0.05), and the awareness was significantly higher among respondents with healthcare-related occupations than among those with other occupations (16.44% vs. 14.22%, P<0.05). Wechat, Weibo, Tik Tok and Kuaishou were main routes to obtain nutritional health knowledge (83.86%). Conclusions The awareness of nutritional health knowledge is low among regular unpaid blood donors in Zhoushan City. Men, middle-aged and elderly residents and residents with a low educational level are targets that should be given a high priority for nutritional health education, and new media may be fully utilized for nutritional health education.

【Objective】 To investigate the risk factors and predictive effectiveness of prostate imaging reporting and data system (PI-RADS) score for patients with clinically significant prostate cancer (CsPCa) whose PI-RADS score was 3, so as to provide evidence for the diagnosis and treatment. 【Methods】 The clinical and multi-parameter magnetic resonance imaging (mpMRI) data of 153 CsPCa patients treated during Jan.2017 and Dec.2021 whose PI-RADS score was 3 were retrospectively analyzed. With PI-RADS score of 3 as the independent risk factor for CsPCa, the other relevant independent risk factors in predicting CsPCa were evaluated. 【Results】 Univariate and multivariate analyses showed that prostate-specific antigen (PSA) density and apparent dispersion coefficient (ADC) were independent risk factors for the diagnosis of CsPCa (P<0.05). Analysis of receiver operating characteristic (ROC) curve showed that combined PSA density and ADC were more effective than PSA density and ADC alone (P<0.05). 【Conclusion】 The combination of PSA density and ADC can guide clinicians to identify high-risk CsPCa patients from patients with PI-RADS score of 3 points.

Objective:The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China.Methods:This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems.Results:According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%).Conclusion:Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

The ketogenic diet(KD) treatment program planned for a 2 years old and 5 months boy suffered from severe cerebral complications after ependymoma operation in the Children′s Hospital of Nanjing Medical University at December 2018 was analyzed retrospectively.The patient developed various complications, including cerebral hemorrhage, hydrocephalus and hernia after the operation of ependymoma, with coma, fever and convulsion, and 1 month of anti-infection and antiepileptic treatment was ineffective.After 2 weeks of 4∶1 KD, fever and convulsion were effectively relieved without obvious side effects.One month later, the patient regained consciousness, demonstrating that KD can be applied to treat severe cerebral complications after ependymoma operation.

With the effective control of viral hepatitis around the world, nonalcoholic steatohepatitis (NASH) will become the main cause of liver transplantation in the next ten years. There is a huge number of NASH patients, but currently no drug has been approved by authorities, which represents a large unmet need in clinical practice. The complex pathogenesis of NASH, heterogeneity of this disease, difficulties in diagnosis, and selection of treatment endpoints have brought great challenges to the research and development of new drugs.

Objective:To investigate the different outcomes of two types of acute kidney injury (AKI) according to standard of Kidney Disease: Improving Global Outcomes-AKI (KDIGO-AKI), and to analyze the risk factors that affect the prognosis of intensive care unit (ICU) patients in China.Methods:A secondary analysis was performed on the database of a previous study conducted by China Critical Care Clinical Trial Group (CCCCTG), which was a multicenter prospective study involving 3 063 patients in 22 tertiary ICUs in 19 provinces and autonomous regions of China. The demographic data, scores reflecting severity of illness, laboratory findings, intervention during ICU stay were extracted. All patients were divided into pure AKI (PAKI) and acute on chronic kidney disease (AoCKD). PAKI was defined as meeting the serum creatinine (SCr) standard of KDIGO-AKI (KDIGO-AKI SCr) and the estimated glomerular filtration rate (eGFR) at baseline was ≥ 60 mL·min -1·1.73 m -2, and AoCKD was defined as meeting the KDIGO-AKI SCr standard and baseline eGFR was 15-59 mL·min -1·1.73 m -2. All-cause mortality in ICU within 28 days was the primary outcome, while the length of ICU stay and renal replacement therapy (RRT) were the secondary outcome. The differences in baseline data and outcomes between the two groups were compared. The cumulative survival rate of ICU within 28 days was analyzed by Kaplan-Meier survival curve, and the risk factors of ICU death within 28 days were screened by Cox multivariate analysis. Results:Of the 3 063 patients, 1 042 were enrolled, 345 with AKI, 697 without AKI. The AKI incidence was 33.11%, while ICU mortality within 28 days of AKI patients was 13.91% (48/345). Compared with PAKI patients ( n = 322), AoCKD patients ( n = 23) were older [years old: 74 (59, 77) vs. 58 (41, 72)] and more critical when entering ICU [acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score: 23 (19, 27) vs. 15 (11, 22)], had worse basic renal function [eGFR (mL·min -1·1.73 m -2): 49 (38, 54) vs. 115 (94, 136)], more basic complications [Charlson comorbidity index (CCI): 3 (2, 4) vs. 0 (0, 1)] and higher SCr during ICU stay [peak SCr for diagnosis of AKI (μmol/L): 412 (280, 515) vs. 176 (124, 340), all P < 0.01]. The mortality and RRT incidence within 28 days in ICU of AoCKD patients were significantly higher than those of PAKI patients [39.13% (9/23) vs. 12.11% (39/322), 26.09% (6/23) vs. 4.04% (13/322), both P < 0.01], while no significant difference was found in the length of ICU stay. Kaplan-Meier survival curve analysis showed that the 28-day cumulative survival rate in ICU in AoCKD patients was significantly lower than PAKI patients (Log-Rank: χ2 = 5.939, P = 0.015). Multivariate Cox regression analysis showed that admission to ICU due to respiratory failure [hazard ratio ( HR) = 4.458, 95% confidence interval (95% CI) was 1.141-17.413, P = 0.032], vasoactive agents treatment in ICU ( HR = 5.181, 95% CI was 2.033-13.199, P = 0.001), and AoCKD ( HR = 5.377, 95% CI was 1.303-22.186, P = 0.020) were independent risk factors for ICU death within 28 days. Conclusion:Further detailed classification (PAKI, AoCKD) based on KDIGO-AKI SCr standard combined with eGFR is related to ICU mortality in critical patients within 28 days.
