Objective:To study the urinary iodine levels of children in Jiangxi Province and provide a basis for prevention and treatment of iodine deficiency disorders and scientific iodine supplementation.Methods:From March to July in 2022, a systematic sampling method was used in 99 counties (cities, districts, abbreviated as counties) in Jiangxi Province. One township (street) was selected from each county in five directions: east, west, south, north and middle. One primary school was selected from each township (street), and 40 non boarding children aged 8 - 10 (half male and half female) were selected from each primary school. One random urine sample was collected to test urinary iodine, and the distribution of urinary iodine in different regions, genders, and ages were compared.Results:A total of 19 842 urine samples were collected from children, with a median urinary iodine level of 181.90 μg/L. The median urinary iodine levels of children in different cities ( H = 1 014.05, P < 0.001), genders ( Z = 6.44, P < 0.001) and ages groups ( H = 29.82, P < 0.001) were compared, and the differences were statistically significant. Conclusion:The urinary iodine level of children in Jiangxi Province is at an appropriate level, but the distribution of urinary iodine is uneven among different regions, genders, and ages, indicating that scientific and precise iodine supplementation is necessary for the prevention and treatment of iodine deficiency disorders.

Objective:To analyze the clinical efficacy and prognostic factors of comprehensive treatment for atypical teratoid / rhabdomyoma tumor (AT/RT).Methods:Clinical data of children diagnosed with AT/RT who underwent radiotherapy in Department of Oncology of Xinhua Hospital affiliated to Shanghai Jiao Tong University School of Medicine from November 2012 to September 2022 were retrospectively analyzed. Pearson Chi-square test or continuous-corrected Chi-square test or Fisher's exact probability method were used for inter-group comparison of categorical variables. Independent sample t-test or Wilcoxon rank-sum test were used for inter-group comparison of continuous variables. Kaplan-Meier method was used to calculate the 1-year and 2-year overall survival (OS) rate and progression free survival (PFS) rate. Univariate and multivariate Cox regression analyses were employed to determine relevant prognostic factors. Results:A total of 45 patients were included, with a male/female ratio of 1.65:1, including 27 children aged ≥3 years old. All patients received surgery and radiotherapy in which 39 patients received chemotherapy, 41 craniospinal irradiation (CSI), and 4 whole brain or focal radiation therapy. The median follow-up was 28 (13.5, 49) months. A total of 14 patients died after comprehensive treatment. The 1-year OS rate was 80.0% and the PFS rate was 71.1%. The 2-year OS rate was 75.5% and the PFS rate was 65.7%. Survival prognostic analysis showed negative imaging assessment after radiotherapy ( HR=0.087, 95% CI: 0.011-0.697, P=0.022) was a favorable factor for PFS. The primary tumor<4.8 cm ( HR=0.221, 95% CI: 0.052-0.935, P=0.040) and CSI ( HR=0.085, 95% CI: 0.011-0.651, P=0.018) were favorable factors for OS. In subgroup analysis, CSI also improved OS in children aged ≥3 years ( HR=0.014, 95% CI: 0-0.470, P=0.017), but there was no significant difference in PFS. In children without cerebrospinal fluid dissemination, negative radiographic results after radiotherapy ( HR=0.066, 95% CI: 0.009-0.481, P=0.007; HR=0.076, 95% CI: 0.008-0.695, P=0.024, respectively) and CSI (HR=0.105, 95% CI: 0.012-0.937, P=0.044; HR=0.054, 95% CI: 0.005-0.629, P=0.020, respectively) were favorable factors for PFS and OS in children, and the primary tumor<4.8 cm also suggested a longer OS ( HR=0.094, 95% CI: 0.013-0.690, P=0.020). Conclusions:Comprehensive treatment including radiotherapy improves clinical prognosis of children with AT/RT. Our study shows that negative imaging results after radiotherapy are associated with PFS improvement. The primary tumor<4.8 cm and CSI are favorable factors for OS. CSI is also a significantly positive prognostic factor in children aged ≥3 years and those without cerebrospinal fluid dissemination.

Objective:To construct the enteral nutrition nursing scheme of ICU patients with abdominal hypertension based on internal abdominal pressure classification, and provide reference for effectively preventing enteral nutrition intolerance of ICU patients with abdominal hypertension.Methods:According to the "6S" evidence pyramid model, searched from top to bottom for relevant literature on enteral nutrition support for ICU patients with abdominal hypertension in databases such as BMJ Best Practice, Cochrane Library, Guidelines International Network, Medlive, UpToDate, PubMed, Ovid, Web of Science, Embase, China National Knowledge Infrastructure, VIP, Wanfang Medicine, Chinese Biomedical Literature. Developed an enteral nutrition care plan for ICU patients with abdominal hypertension based on intra-abdominal pressure grading, with a search date from database establishment to January 25, 2023. The Delphi expert letter consultation method was used to conduct two rounds of letter consultation with 20 experts to solicit expert opinions and determine the intervention plan.Results:The age of 20 experts was (43.75 ± 5.28) years old, with a working experience of (22.00 ± 6.98) years.

The established enteral nutrition nursing scheme for ICU patients with abdominal hypertension based on intra-abdominal pressure classification is reliable and scientific, and can provide reference for clinical nursing practice of enteral nutrition for ICU patients with abdominal hypertension.

Objective:To analyze the quality control test results of urine fluoride laboratories in Jiangxi Province, and support reliable data for the monitoring and prevention of fluorosis.Methods:From 2019 to 2021, the Jiangxi provincial urine fluoride laboratories used the "Determination of Fluoride in Urine-Ion Selective Electrode Method" (WS/T 89-2015) to detect quality control samples. Origin 9 software was used to analyze the data, and Youden plots and deviation bar plots were produced. The results were evaluated based on the Z-score (qualified: │Z│ ≤2, basically qualified: 2 < │Z│ < 3, unqualified: │Z│ ≥3).Results:The qualified rate of quality control assessment results of urine fluoride laboratories in Jiangxi Province was 95.00% (38/40) . Most of urine fluoride laboratories had scores of │Z│ < 2, and two laboratories had scores │Z│≥3 in 2019 and 2020.Conclusion:The quality control assessment results of urine fluoride laboratories in Jiangxi Province are relatively satisfactory, but some laboratories still need to further improve their detection capabilities.

Objective:To evaluate the efficacy and safety of oral anisodine hydrobromide tablets in the treatment of nonarteritic anterior ischemic optic neuropathy (NAION).Methods:A multicenter nonrandomized controlled trial was conducted.A total of 282 acute NAION patients (282 eyes) were recruited from 16 hospitals in China from July 2020 to May 2021.Patients were divided into two groups according to treatment methods, which were control group (124 cases, 124 eyes) receiving regular treatment including citicoline sodium plus Ginkgo biloba leaf liquid extract or Ginkgo biloba leaf extract tablets plus mecobalamin, and experimental group (158 cases, 158 eyes) receiving treatment in control group plus oral anisodine hydrobromide tablets 1 mg, twice daily for 2 to 3 months.Best corrected visual acuity (BCVA), visual field index (VFI), peripapillary retinal nerve fiber layer (pRNFL) and radial peripapillary capillary vessel density (RPC) were assessed at 1, 2, 3, and 6 months after enrollment using the standard decimal visual acuity chart, 750i Humphery visual field analyzer, Cirrus HD-OCT 4000/Cirrus HD-OCT 5000, RTVue-XR optical coherence tomography respectively.The primary outcomes were BCVA and VFI, and the secondary outcomes were pRNFL, RPC, and the side effects during the follow-up.The study adhered to the Declaration of Helsinki.All patients were fully informed about the treatment and purpose of this study and voluntarily signed the informed consent form.The study protocol was approved by Chinese PLA General Hospital (No.S2020-021-01). Results:In all, 242 patients (242 eyes) completed the follow-up of BCVA, and 98 patients (98 eyes) completed the VFI follow-up.In terms of visual function, BCVA and VFI improved significantly over time in the two groups, and BCVA and VFI were better in experimental group than in control group at various follow-up time points (all at P<0.05). In terms of structure, pRNFL gradually decreased in both groups with the extension of treatment, and pRNFL was significanthy thinner in experimental group than in control group at various follow-up time points (all at P<0.05). There was no significant difference in RPC between the two groups at the last follow-up ( P>0.05). There were two cases with side effects and one case was discontinued due to side effects 25 days after enrollment. Conclusions:Oral anisodine hydrobromide can improve visual acuity and visual field in NAION and accelerate the regression of optic disc edema, with good safety.

Abstract: Objective　To understand the epidemiological characteristics of the migratory bird population with hypertension in Hainan and to provide a basis for the health management of the migratory bird population. Methods　One hundred and eighty migratory birds with hypertension who had lived in in the Mangrove Bay community of Chengmai, Hainan for 3 months or more were selected as the study population. Demographic data, including gender, age, ethnicity, occupation, medication use, family history of hypertension, hometown living environment, Hainan living environment (presence of water area and greenbelt around the residence, type of water area and greenbelt), smoking and alcohol consumption, and height and weight were collected by questionnaire and physical examination to investigate the epidemiological characteristics of the study subjects, and unconditional dichotomous logistic regression analysis was used to identify factors affecting the reduction of blood pressure among the hypertensive migratory bird population before and after taking medication in Hainan. Results　A total of 180 study subjects were included, including 77 (42.8%) males and 103 (57.2%) females, with 78 (43.3%) subjects aged ≤65. The hypertension levels were: 87 (48.3%) had normal high blood pressure, 56 (31.1%) had grade 1 hypertension and 37 (20.6%) had grade 2 hypertension. The higher the blood pressure classification, the lower the percentage of migratory individuals whose blood pressure dropped during their stay in Hainan. Age, hypertension classification, dietary habits, living environment, body mass index (BMI), and alcohol consumption were associated with a decrease in blood pressure during Hainan among the study participants who took hypertension medication regularly. Salty diet (OR=2.778, 95%CI:1.070-7.213, P=0.036) and alcohol consumption (OR=2.686, 95%CI:1.042-6.925, P=0.041) were unfavorable factors for lower diastolic blood pressure before taking medication; overweight (OR=3.487, 95%CI:1.306-9.310, P=0.013) was an unfavorable factor in the reduction of diastolic blood pressure after taking medication. Conclusion　The blood pressure reduction is more significant in migratory individuals in migratory individuals under 65 years old, with a light diet, no alcohol consumption and normal BMI. Environmental factors, age, dietary habits and lifestyle are the main causes of blood pressure, which can provide a reference basis for the health management of the migratory birds with hypertension in Hainan.

The paper reported a case of a young male patient, with graft-versus-host disease (GVHD) multi-organ involvement lesions after allo-hematopoietic stem cell transplantation. The patient had diverse clinical manifestations, and overlapping acute and chronic disease processes. Acute GVHD were mainly hyperbilirubinemia, with or without elevated transaminase, bloody watery stools; chronic GVHD were highlighted by extensive skin depigmentation, oral mucosal ulcer, sick nails, etc., and chronic signs, such as membranous nephropathy, polyserositis and pulmonary restrictive ventilatory insufficiency. The diagnosis of chronic GVHD mainly relies on medical history combined with clinical manifestations, and it's needed to exclude infections, drugs and tumors. Besides, the rate of missed diagnosis and misdiagnose is high, and it requires multidisciplinary diagnosis and treatment. Combined with the literature review, it indicates that there is a greater risk of GVHD in the male recipient with female donor, and peripheral blood stem cell transplant patients have a higher incidence than bone marrow transplant patients after hematopoietic stem cell transplantation, but the effect of the graft-versus-leukemia exists. Currently, glucocorticoids therapy with or without calcineurin inhibitors are the first-line treatment for GVHD, but the overall prognosis is poor.

Objective:To explore the association between grip strength and cognitive function in elderly people aged 65 years and over.Methods:Information on grip strength, cognitive function, and lifestyle in the elderly population aged 65 years and over in Wuhan was collected by unified professionally trained investigators.A total of 533 study subjects aged(70.7±5.1)years were grouped by quartile into four grip strength groups of Q1(<18.6 kg), Q2(18.6~24.1 kg), Q3(24.2~31.1 kg), Q4(>31.1 kg).Multiple linear regression and Logistic regression analyses were used to analyze the relationship of grip strength with cognitive function scores and cognitive impairment.Results:The mean grip strength of the 533 subjects was(24.94±9.15)kg.After adjusting for sociodemographic characteristics, lifestyle factors, history of diseases, as compared with grip strength Q1 group, the linear regression coefficients(Beta value)of cognitive scores and 95% confidence intervals(95% CI)showed statistically significantly positive correlation[0.45(-0.36, 1.26)、0.40(-0.52, 1.32)and 1.19(0.07, 2.31), all P<0.05]only between cognitive scores and grip strength Q2、Q3 and Q4 value; and the odds ratio and 95% CI of incidence of cognitive impairment were 0.97(0.43, 2.21)for grip strength Q2, 0.79(0.30, 2.06)for grip strength Q3, and 0.22(0.05, 0.92)for grip strength Q4.Considering grip strength as the continuous variable, the risk of cognitive impairment was decreased by 6% and the cognitive score was increased by 0.07 with per 1kg increase of grip strength. Conclusions:The results of this study suggest that there is a positive correlation between grip strength and cognitive function in the elderly population, and a lower grip strength is related to increased risk of cognitive impairment.More attention should be paid to the grip strength of the elderly in the community.
