Objective:To determine the genetic causes of dystonic cerebral palsy (DCP) of unknown etiology by using whole exome and mitochondrial gene detection methods, and to analyze clues for early identification of DCP.Methods:This was a retrospective analysis of clinical data describing 21 children with unknown etiology and DCP-like phenotypes. It involved collecting a detailed medical history, biochemical testing, neuroimaging, electroencephalography and hematuria metabolic screening. Peripheral blood was collected from the children, their parents and their siblings. Genomic DNA was extracted, and whole exome and/or mitochondrial gene sequencing was performed to obtain variant sites and annotations. The candidate variants were verified by Sanger sequencing.Results:No clear perinatal risk factors were found in the 21 cases, though there was 1 case of family history. Laboratory tests found increased lactic acid in 3 and abnormal thyroid function in 2 cases. The neuroimaging showed lesions in the basal ganglia in 2 cases, delayed myelination in 6 cases, sometimes with cortical dysplasia, a wide extracerebral space and/or a thin corpus callosum. The images of 11 of the children were normal. Later follow-up showed changes in the brain magnetic resonance images (MRIs) of 2 of the children. Pathogenic or likely pathogenic candidate variants were identified in 15 of the 21 children (71%) within 12 genes: TH, SLC16 A2, RHOBTB2, FOXG1, IFIH1, WDR45, MT- ATP6, KIAA2022, GNB1, GNAO1, SLC2 A1 or NACC1. Fifteen of the children received a precise diagnosis. Genetic testing found heterozygous variants of ATP1 A2, SPR, ATP1 A3, MED13 L or NR4 A2 genes in the remaining six children, all of which were non-pathogenic variants. Conclusions:The absence of perinatal high-risk factors, a positive family history, and a normal or progressive brain MRI can be used as early clues to identify atypical DCP cases. TH, SLC16 A2, RHOBTB2, FOXG1, IFIH1, WDR45, MTATP6, KIAA2022, GNB1, GNAO1, SLC2 A1 and NACC1 variants belong to the spectrum of DCP-related pathogenic genes, and attention should be paid to the interpretation of genomic analysis results.

Objective To assess the effect of early nutritional intervention on the patients with respiratory diseases at nutritional risk. Methods A total of 130 patients with respiratory disease who were hospitalized in Shanghai Fifth People’s Hospital, Fudan University between May 2023 and December 2024 and had a nutritional risk screening 2002 score ≥3 points. Based on the initiation time of nutritional intervention, patients were divided into an early group (≤5 days, n＝65) and a late group (＞5 days, n＝65). Results In the early group, prealbumin (P-ALB) and retinol-binding protein (RBP) levels were significantly higher (P＜0.01), C-reactive protein (CRP), procalcitonin (PCT) levels were significantly lower after intervention (P＜0.05). Compared with the late group, the hospital costs were lower and hospital stays were shorter in the early group (P＜0.001). Spearman analysis showed ALB, P-ALB, and total protein (TP) were negatively correlated with hospital costs (r＝－0.37, －0.20, and－0.22, P＜0.05). RBP, ALB, P-ALB, and lymphocyte count (LYM) were negatively correlated with CRP (r＝－0.30, －0.26, －0.37, －0.18, P＜0.01), RBP, ALB, P-ALB, hemoglobin (HB), and TP were negatively correlated with PCT (r＝－0.23,－0.36, －0.40, －0.30, －0.19, P＜0.05). Conclusions For patients with respiratory diseases, early nutritional assessment should be underwent, and for patients with nutritional risk screening 2002 score ≥3 points, early nutritional intervention could improve the nutritional status and alleviate inflammatory response, promote recovery, shorten the hospital stays.

Widespread utilization of glyphosate has led to environmental residues,posing potential threats to ecological systems and human health.Traditional methods for detection of glyphosate are limited by specialized equipment and operational techniques,resulting in inefficient responses.Therefore,it is urgent to develop a convenient,sensitive and accurate detection method for detection of glyphosate.Herein,a new naphthalenesulfonamide-based"Turn-on"fluorescent probe was synthesized using 2-chloroaniline and dansyl chloride as raw materials through a one-step process,which showed a good linear relationship between the glyphosate concentration in concentration range of 0.003-70 μmol/L and the fluorescence intensity(R2=0.995),with a detection limit of 2.73 nmol/L(S/N=3).Analytical techniques such as nuclear magnetic resonance(NMR)spectroscopy and high-resolution mass spectrometry(HRMS)were used to investigate the interaction mechanism between the fluorescent probe and glyphosate.The results indicated that a nucleophilic substitution reaction occurred between the probe and the secondary amine(—NH—)of glyphosate,inducing a photoinduced electron transfer(PET)effect which enhanced the fluorescence intensity by 11.2 times.The probe showed good anti-interference ability towards coexisting metal ions,anions and pesticides in water.When applied to determination of glyphosate in the samples such as tap water,river water(Xiangxi River Reservoir),soil,soybeans,and corn,the spiking recoveries ranged from 94.7％to 109.9％,demonstrating the high accuracy and broad applicability of this detection method.A portable test strip based on this fluorescent probe was developed for rapid semi-quantitative analysis of glyphosate.The developed method was rapid,sensitive,and portable,providing theoretical and technical support for on-site measurement of environmental contaminants.

Objective To summarize the epidemiological and clinical features of infectious diseases of the central nervous system(CNS)by a single-center analysis.Methods A retrospective analysis was conducted on the data of 1247 cases of CNS infectious diseases diagnosed and treated in the First Medical Center of PLA General Hospital from 2001 to 2020.Results The data for this group of CNS infectious diseases by disease type in descending order of number of cases were viruses 743(59.6％),Mycobacterium tuberculosis 249(20.0％),other bacteria 150(12.0％),fungi 68(5.5％),parasites 18(1.4％),Treponema pallidum 18(1.4％)and rickettsia 1(0.1％).The number of cases increased by 177 cases(33.1％)in the latter 10 years compared to the previous 10 years(P<0.05).No significant difference in seasonal distribution pattern of data between disease types(P>0.05).Male to female ratio is 1.87︰1,mostly under 60 years of age.Viruses are more likely to infect students,most often at university/college level and above,farmers are overrepresented among bacteria and Mycobacterium tuberculosis,and more infections of Treponema pallidum in workers.CNS infectious diseases are characterized by fever,headache and signs of meningeal irritation,with the adductor nerve being the more commonly involved cranial nerve.Matagenomic next-generation sequencing improves clinical diagnostic capabilities.The median hospital days for CNS infectious diseases are 18.00(11.00,27.00)and median hospital costs are ￥29,500(￥16,000,￥59,200).The mortality rate from CNS infectious diseases is 1.6％.Conclusions The incidence of CNS infectious diseases is increasing last ten years,with complex clinical presentation,severe symptoms and poor prognosis.Early and accurate diagnosis and standardized clinical treatment can significantly reduce the morbidity and mortality rate and ease the burden of disease.

Morita therapy has been bom for more than 100 years.Inpatient Morita therapy is highly oper-able and easy to master.It can improve many refractory neuroses through four-stage treatment.But more neuroses are treated in outpatient clinics,and Morita therapy cannot be used in hospitalized patients.Therefore,the formula-tion of expert opinions on outpatient operations is particularly important.This paper is based on domestic and for-eign references,and after many discussions by domestic Morita therapy experts,and then drew up the first version of the expert opinions on operation of outpatient Morita therapy.Meanwhile the operation rule of Morita therapy in three stages of outpatient treatment was formulated:in the etiological analysis stage,under the theoretical guidance of Morita therapy,analyze the pathogenic factors,to improve treatment compliance and reduce resistance;during the operating stage,guide patients to engage in constructive and meaningful actions,realizing the achievement of letting nature take its course principle;in the cultivating character and enriching life stage,pay attention to positive infor-mation,expanding the scope and content of actions,improving the ability to adapt to complex life,and preventing recurrence caused by insufficient abilities.It will lay a foundation for the promotion of Morita therapy in domestic outpatient clinics,so that more patients with neurosis and other psychological diseases could receive characteristic Morita therapy treatment in outpatient clinics.

Objective:To learn about the operation of fluoride reduction and water improvement projects, the current situation of water fluoride level and the changing trend of fluorosis in drinking water-borne endemic fluorosis areas in Shaanxi Province, and to evaluate the effect of prevention and control measures.Methods:From March 2014 to December 2021, 15 endemic villages in drinking water-borne endemic fluorosis areas of Dali, Dingbian, Jingbian, Jingyang and Liquan counties in Shaanxi Province were selected as monitoring villages to investigate the operation of water improvement projects. Water samples were collected, and the water fluoride level was detected according to the "Standard Examination Methods for Drinking Water - Nonmetal Parameters" (GB/T 5750.5-2006). "Diagnosis of Dental Fluorosis" (WS/T 208-2011) was done to detect dental fluorosis in all children aged 8 - 12 who were born and lived in the monitoring village. Using "Diagnostic Standard for Endemic Skeletal Fluorosis" (WS/T 192-2008) and "Determination of Fluoride in Urine - Ion Selective Electrode Method" (WS/T 89-2015), X-ray examination and urine fluoride level test were performed on adults over 25 years old who had lived in the monitoring village for more than 5 years, respectively.Results:From 2014 to 2021, a total of 122 water improvement projects were investigated, all of which were in normal operation. The qualified rate of water fluoride increased from 81.25% (13/16) in 2014 to 100.00% (11/11) in 2021. A total of 5 595 children aged 8 - 12 were examined, 1 790 children with dental fluorosis were detected, with a detection rate of 31.99%. The detection rate of dental fluorosis in children decreased from 52.05% (304/584) in 2014 to 9.68% (93/961) in 2021, showing an overall downward trend (χ 2trend = 533.76, P < 0.001). In 2014, 791 adults were examined, and 256 patients with skeletal fluorosis were detected, the detection rate was 32.36%. In 2019, 770 adults were examined, and 88 patients with skeletal fluorosis were detected, with a detection rate of 11.43%. The detection rate of skeletal fluorosis in adults in 2019 was lower than that in 2014, and the difference was statistically significant (χ 2 = 99.54, P < 0.001). In 2014, 754 adult urine samples were collected, and the geometric mean of urine fluoride was 2.571 mg/L. In 2019, 770 adult urine samples were collected, and the geometric mean of urine fluoride was 1.292 mg/L. The geometric mean of urine fluoride in adults in 2019 was lower than that in 2014, and the difference was statistically significant ( Z = - 12.74, P < 0.001). Conclusions:From 2014 to 2021, the water improvement projects in drinking water-borne endemic fluorosis areas in Shaanxi Province are running normally, and the qualified rate of water fluoride has increased. The incidence of dental fluorosis in children and skeletal fluorosis in adults has decreased. In the later stage, it is necessary to continuously strengthen the monitoring and management of water improvement projects to prevent the rebound of water fluoride from causing residents' illness.

Diabetic kidney disease(DKD),as a major causative agent of end-stage renal disease(ESRD),has a complex pathogenesis in which mitochondrial dysfunction and lipid metabolism disorders play key roles.Mitochondrial dysfunction leads to excessive reactive oxygen species(ROS)production,inhibits fatty acid β-oxidation,and creates lipotoxicity,which is the key to podocyte damage in DKD.Meanwhile,lipid metabolism disorder exacerbates ectopic accumulation of fat,activates inflammation and oxidative stress,and affects insulin signalling,which further inhibits mitochondrial function and drives DKD progression.Therefore,an in-depth understanding of the association between mitochondrial dysfunction and podocyte lipid metabolism in DKD is important for DKD treatment.This review discusses the basic profiles of DKD,mitochondrial dysfunction,and podocyte lipid metabolism,and their interactions,as well as discussing the current status of the DKD treatment,with a view to providing references for the research and treatment of DKD.

Objective To investigate the attributable risk(AR)of Acinetobacter baumannii(AB)infection in criti-cally ill patients.Methods A multicenter retrospective cohort study was conducted among adult patients in inten-sive care unit(ICU).Patients with AB isolated from sterile body fluid and confirmed with AB infection in each cen-ter were selected as the infected group.According to the matching criteria that patients should be from the same pe-riod,in the same ICU,as well as with similar APACHE Ⅱ score(±5 points)and primary diagnosis,patients who did not infect with AB were selected as the non-infected group in a 1:2 ratio.The AR was calculated.Results The in-hospital mortality of patients with AB infection in sterile body fluid was 33.3％,and that of non-infected group was 23.1％,with no statistically significant difference between the two groups(P=0.069).The AR was 10.2％(95％CI:-2.3％-22.8％).There is no statistically significant difference in mortality between non-infected pa-tients and infected patients from whose blood,cerebrospinal fluid and other specimen sources AB were isolated(P＞0.05).After infected with AB,critically ill patients with the major diagnosis of pulmonary infection had the high-est AR.There was no statistically significant difference in mortality between patients in the infected and non-infec-ted groups(P＞0.05),or between other diagnostic classifications.Conclusion The prognosis of AB infection in critically ill patients is highly overestimated,but active healthcare-associated infection control for AB in the ICU should still be carried out.
