BACKGROUND:Impaired postural control is an important risk factor for falls and secondary damage in patients with idiopathic normal pressure hydrocephalus.Most of the existing studies have analyzed the gait parameters of patients during straight-line walking,but few have analyzed the postural stability characteristics of patients during static and dynamic activities. OBJECTIVE:To analyze the characteristics of postural stability in elderly patients with idiopathic normal pressure hydrocephalus. METHODS:Twenty-two patients clinically diagnosed with idiopathic normal pressure hydrocephalus at the Department of Neurosurgery,Huadong Hospital Affiliated to Fudan University,Shanghai,China,from September 2022 to February 2023 were selected as the patient group,and 18 healthy accompanying family members were selected as the healthy control group.The postural stability characteristics of the subjects were assessed using the Timed Up-and-Go Test,Multi-Directional Reach Test,Berg Balance Scale,and Static Balance Function Test(reaction time,speed of movement,directional control,maximum offset distance,and endpoint travel). RESULTS AND CONCLUSION:The time required to complete the Timed Up-and-Go Test was significantly longer in the patient group than in the healthy control group(P＜0.05).The results of the stretching test in the four directions of anterior,posterior,leftand right were significantly lower in the patient group than in the healthy control group(P＜0.05).The Berg Balance Scale scores in the patient group were lower than those in the healthy control group(P＜0.05).In the Static Balance Function Test,the results of reaction,movement speed,directional control,maximum offset distance and endpoint travel index were smaller in the patient group than the healthy control group(P＜0.05).To conclude,patients with idiopathic normal pressure hydrocephalus exhibit overall postural control deficits,and impaired reaction and execution abilities make these patients unable to make timely and accurate motor responses in the face of disturbances from internal or external sources,resulting in postural instability and increasing the risk of falls.

Based on the clinical thinking of combining diseases and patterns， we combined disease identification， pattern differentiation， and constitution identification， and put forward the theory of identifying and treating critical hypertension， which is "examining the symptoms first， identifying the constitutions as reference， and combining the diseases and patterns". Firstly， the starting point of identifying the disease is to examine the symptoms， and those with precise diagnosis and strong specificity will be diagnosed with the disease， while those with relatively broad diagnosis and fuzzy characteristics will be emphasised on identifying constitutions and differentiating patterns. Focusing on the impact of constitution identification on disease identification and pattern differentiation， constitution identification could be the basis when no symptoms to identify， and based on the theory of "constitution-disease correlation" and "constitution-pattern correlation" to improve the understanding of borderline hypertension from the group and individual level， which helps to identify and predict the development of the diseases and patterns； if the symptoms are complicated and difficult to identify， it is necessary to take syndrome as the outline， use the syndrome to unify the disease， and then refer to the constitution to legislate and prescribe medications. This paper summarizes the traditional Chinese medicine clinical differentiation and treatment strategy of borderline hypertension clear and easy to grasp， with a view to provide a feasible and efficient reference for prevention and treatment of borderline hypertension with traditional Chinese medicine.

Objective:To systematically review the qualitative research on the care experience of caregivers of palliative care for minors, in order to provide a reference for formulating a care plan that is more in line with the needs of palliative care for minors and their families.Methods:The Cochrane Library, Australia Joanna Briggs Institute Evidence-based Health Care Center Library, Embase, PubMed and Web of Science, CINAHL, China National Knowledge Infrastructure, Wanfang Database, VIP Database and China Biology Medicine Disc were searched by computer for literature on qualitative research on care experience of underage hospice care caregivers from the establishment of the database to December 30, 2023.Results:A total of 11 articles were included and 70 research results were extracted, which were summarized into 7 new categories and formed 2 integrated results: professional caregivers and relative caregivers had multiple care burden, and need multiple care support; professional caregivers and relative caregivers can shoulder the care responsibility of children together, actively respond to the difficulties in care, gain personal care experience and growth.Conclusions:Hospice care for minors has its own characteristics, and caregivers have various care burdens and needs. Special attention should be paid to the emotional experience and care demands of caregivers, and targeted support and protection should be provided to promote the construction of hospice care team for minors in China and improve the level of hospice care for minors in China.

Objective:To study the short-term clinical outcomes of different courses of antenatal corticosteroids (ACS) for preterm twins.Methods:From January 2017 to December 2021, preterm twins with gestational age (GA) 24-34 weeks admitted to the neonatal ward of our hospital and received ACS were retrospectively studied. The infants were assigned into single-course group, partial-course group and multiple-course group according to ACS courses. The short-term clinical outcomes were compared among the groups. SPSS software version 25.0 was used for statistical analysis.Results:A total of 286 infants were enrolled in this study, including 128 in single-course group, 89 in partial-course group and 69 in multiple-course group. Compared with single-course group, the risks of neonatal respiratory distress syndrome (RDS) in both partial-course group ( OR=2.332, 95% CI 1.028-5.293, P=0.043) and multiple-course group ( OR=3.872, 95% CI 1.104-13.584, P=0.034) were higher. The birth length in multiple-course group ( β=-0.016, 95% CI -0.029 - -0.002, P=0.024) was lower than single-course group. Conclusions:The risks of neonatal RDS in preterm twins are higher in partial-course and multiple-course of ACS. A full course of ACS should be used to prevent neonatal RDS until further evidence of effectiveness is available.

Objective:To investigate the clinical manifestations, diagnosis, and treatment methods of Lophomonas blattarum infection combined with paragonimiasis in children, and improve pediatricians' understanding of the disease. Methods:The clinical data of two children with Lophomonas blattarum infection combined with paragonimiasis who received treatment in the Department of Pediatrics of The First People's Hospital of Yunnan Province were retrospectively analyzed. Children's clinical manifestation and diagnosis and treatment were analyzed. Relative literature was reviewed. Results:Case 1 had the onset of gastrointestinal symptoms. Case 2 had the onset of headache and liver dysfunction. Routine blood tests showed elevated eosinophils two cases and sputum examination results revealed the presence of live eggs of Lophomonas blattarum and paragonimiasis in two cases. Fecal roundworm eggs were also detected in case 1. Follow-up results showed that both cases were cured after treatment with metronidazole injection and praziquantel tablets. Conclusion:Lophomonas blattarum infection is a relatively rare opportunistic infection. Paragonimiasis is a natural parasitic disease that affects both humans and animals. Mixed infection of the two pathogens is rare. We hope that the findings from this paper will broaden clinical physicians' thoughts and guide clinical practice.

Objective:To investigate the nutritional risk and the incidence of malnutrition in children with recurrent abdominal Henoch Schonlein purpura(HSP), and observe the changes in the incidence of malnutrition after nutritional intervention.Methods:We retrospectively analyzed 90 children diagnosed with recurrent HSP in our hospital from 2017 to 2019.The cases were divided into two groups according to whether nutritional intervention was performed.The cases from January 2017 to May 2018 were chosen as the control group( n=42), and the cases from June 2018 to December 2019 were chosen as the experimental group( n=48). Based on the treatment of the primary disease, the high nutritional risk cases in experimental group were treated with extensively hydrolysed infant formula for nutritional intervention.The children were evaluated for nutritional risk with the STRONGkids nutrition tool.According to the score results, they were divided into high nutritional risk group and medium nutritional risk group.The Z score was used to evaluate malnutrition, and the degree of malnutrition was compared at admission and discharge. Results:Eighty-one children (90.0%) with recurrent abdominal allergic purpura had a high nutritional risk, 9 cases (10.0%)had a medium nutritional risk.There was no significant difference in the incidence of moderate and severe malnutrition between experimental group and control group at admission[39.6% (19/48) vs.40.5% (17/42), P>0.05]. The incidence of moderate and severe malnutrition in control group was higher than that in experimental group at discharge[66.7% (28/42) vs.22.9% (11/48), P<0.05]. Conclusion:In children with recurrent abdominal HSP, due to severe gastrointestinal symptoms and a high incidence of high nutritional risk, nutritional intervention with extensively hydrolysed infant formula can avoid the occurrence or aggravation of iatrogenic malnutrition during hospitalization.

Objective:To analyze the changes of cerebral perfusion level and its relationship with cognitive impairment in patients with first anterior circulation acute ischemic post-stroke cognitive impairment.Methods:From March 2018 to March 2020, 70 patients with acute ischemic stroke in the first anterior circulation who were treated in the Department of Neurology of Kailuan General Hospital affiliated to North China University of Technology and met the inclusion and exclusion criteria were retrospectively analyzed.The mini-mental state examination was used to divide 36 cases of post-stroke cognitive impairment group and 34 cases of post-stroke cognitive impairment group.All the selected patients were examined by computed tomography(CT) and diffusion-weighted MR imaging(MRI-DWI) to determine the diagnosis and distribution of lesions; detection of cerebral artery stenosis by MRA; apply 3D pseudo-continuous arterial spin labeling(3D-pCASL) perfusion imaging, set the post label delay 1.5 s and 2.5 s to detect cerebral perfusion level.Results:(1)There was no statistical significance between the two groups in the comparison of basic clinical data.(all P>0.05). (2) The proportion of patients with middle cerebral artery, anterior cerebral artery and internal carotid artery ≥1 or ≥2 moderate and severe stenosis / occlusion on the focal side in the post-stroke cognitive impairment group (91.67%(33/36), 33.33%(12/36)) was higher than that in the post-stroke non-cognitive impairment group (23.53%(8/34), 8.82%(3/34)); the proportion of patients with moderate and severe stenosis / occlusion of MCA and ICA on the focal side in the post-stroke cognitive impairment group (69.44%(25/36), 44.44%(16/36)) was higher than that in the post-stroke cognitive impairment group (14.71%(5/34), 11.76%(4/34)), and the difference was statistically significant(χ 2 values were 33.455, 6.239, 21.394, 9.150, all P<0.05). (3) The proportion of patients with ≥ 2 cerebral infarction lesions in the post-stroke cognitive impairment group (61.1%(22/36))was higher than that in the post-stroke cognitive impairment group (38.03%(27/71))than that in the non-stroke group (20.6%(7/34), 19.05%(8/42)), and the difference was statistically significant(χ 2=11.833, 4.447, all P<0.05). PLD 2.5 s, the CBF value of frontal lobe infarction in post-stroke cognitive impairment group((31.516±8.333) mL/(100 g·min)) was lower than that in post-stroke non-cognitive impairment group((45.442±8.281) mL/(100 g·min)), the difference was statistically significant( t=3.835, P<0.05). Correlation analysis showed that the CBF value of PLD 2.5 s frontal infarction lesion was positively correlated with MMSE score( r=0.738, P<0.05). (4) The proportion of patients with ≥ 1 or ≥ 2 hypoperfusion areas (frontal lobe, temporal lobe, parietal lobe) on the focal side of PLD 1.5 s and 2.5 s after stroke (88.89%(32/36), 88.89%(32/36), 77.78%(28/36), 66.67%(24/36)) were higher than those without cognitive impairment after stroke (67.65%(23/34), 8.82%(3/34), 29.41%(10/34), 0), the difference was statistically significant(χ 2 values were 4.686, 44.837, 16.483, 34.493, all P<0.05). At PLD 1.5 s, CBF values of frontal lobe and parietal lobe in cerebral hypoperfusion area ((20.260±5.266) mL/(100 g·min), (17.664±3.947) mL/(100 g·min)) in patients with cognitive impairment after stroke were lower than those in patients without cognitive impairment ((33.442±10.563) mL/(100 g·min), (28.071±6.913) mL/(100 g·min)), the difference was statistically significant( t values were 3.392, 6.225, all P<0.05), at PLD 2.5 s, the CBF value after compensatory perfusion of frontal lobe, parietal lobe and temporal lobe in the post-stroke cognitive impairment group ((37.732±8.355) mL/(100 g·min), (32.942±6.459) mL/(100 g·min), (39.282±7.443) mL/(100 g·min)) was lower than that in the non cognitive impairment Group ((57.189±9.965) mL/(100 g·min), (52.415±7.017) mL/(100 g·min), (49.258±8.912) mL/(100 g·min)), the difference was statistically significant( t values were 5.443, 10.227, 2.950, all P<0.05). Correlation analysis found that the CBF value of the frontal lobe and parietal lobe of the PLD 1.5 s lesion area and the CBF value of the PLD 2.5 s hypoperfusion brain area after the perfusion of the frontal lobe, parietal lobe, and temporal lobe were positively correlated with the MMSE score( r values were 0.693, 0.675, 0.823, 0.799, 0.545, all P<0.05). Conclusion:Patients with first anterior circulation acute ischemic post-stroke cognitive impairment often have extensive hypoperfusion in the peripheral cerebral region, the occurrence of cognitive impairment after the first anterior circulation acute ischemic post-stroke cognitive impairment is related to the decrease of the perfusion level of the infarct lesion and the brain area around the lesion.

Objective To analyze peripheral blood hemogram, lymphocyte micronucleus and chromosomal aberrations of radiologists, so as to provide basis for occupational protection and health monitoring of radiologists. Methods Lymphocyte micronucleus, chromosome and blood hemogram analysis were performed on 127 radiologists who received health examinations in 2015, 2017 and 2019, and they were assigned to the radiation group. In addition, 133 medical staff with no history of radiation exposure were selected as the control group. Results The micronucleus rate and chromosome aberration rate of the radiation group were higher than those of the control group, and the white blood cell and platelet counts were lower than those of the control group, both of which were statistically significant (P < 0.05). The total number of white blood cells in peripheral blood of 127 radiologists decreased gradually with the increase of exposure time to ionizing radiation, and the chromosome aberration rate increased gradually, all of which had statistical significance (P < 0.05). The rate of chromosomal aberration was higher in radiologists with damage work age of more than 20 years than in the low-work age group, and there was no statistical significance between different damage work age (P > 0.05). The chromosome aberration rate of nuclear medicine and interventional therapy was higher than that of other types, with statistical significance (P < 0.05). Conclusion Long-term exposure to low-dose ionizing radiation can reduce the total number of white blood cells and increase the chromosome aberration rate of radiologists. It is necessary to strengthen the protective measures for radiologists to reduce the degree of ionizing radiation damage, especially to strengthen the occupational protection for radiologists in nuclear medicine and interventional therapy.

Immune checkpoint inhibitors are able to reactivate the immune system therefore enhance the anti-tumor effects. However, over-activated T cells may induce immune related adverse events (irAEs). Hematological irAEs are rarely reported, which mainly represent as mono-lineage cytopenia or pancytopenia, including autoimmune hemolytic anemia (AIHA), immune thrombocytopenia (ITP), neutropenia and aplastic anemia, sometimes even lethal, such as hemophagocytic lymphohistiocytosis. The clinical manifestations of hematological irAEs will be summarized and recommendations of diagnosis and treatment are proposed.

Immune checkpoint inhibitors (ICIs) have made remarkable breakthroughs in cancer treatment. However, the widely use of ICIs is associated with a spectrum of immune-related adverse events (irAEs). These adverse events can affect any organ system. In this article, we have made a systemic review about the clinical characteristics of rheumatic irAEs, and also summarized irAEs in patients with pre-exsiting rheumatic disease. We also focus on the management of rheumatic irAEs.
