Objective To explore the relationship between the level of Caveolin-1 and high mobility group protein B1(HMGB-1)in cerebrospinal fluid and the severity of sepsis and their predictive value.Methods A total of 102 children with sepsis were selected in a hospital from June 2021 to December 2023.According to neonatal critical case scoring criteria,the children were divided into mild group(n=41)and severe group(n=61).According to the diagnostic criteria of purulent meningitis and the results of cerebrospinal fluid examina-tion,the children were divided into sepsis complicated with purulent meningitis group(n=16)and simple sepsis group(n=86).The clinical data of the children were collected,and the levels of Caveolin-1,HMGB-1 and inflammatory factors[hypersensitive C-reactive protein(hs-CRP),procalcitonin(PCT)and tumor necro-sis factor-α(TNF-α)]in cerebrospinal fluid of the children were detected by enzyme-linked immunosorbent assay.Multivariate Logistic regression analysis was conducted to analyze the factors affecting the severity of sepsis,and the receiver operating characteristic curve was drawn to analyze the diagnostic value of Caveolin-1 and HMGB-1 in the severity of sepsis and the prediction value of purulent meningitis in the children.Results Compared with mild group,cerebrospinal fluid levels of Caveolin-1 and HMGB-1 in severe group were signifi-cantly increased,and the difference was statistically significant(P<0.05).The levels of PCT,hs-CRP and TNF-α in severe group were significantly higher than those in mild group,and the difference was statistically significant(P<0.05).Multivariate Logistic regression analysis showed that PCT,hs-CRP,TNF-α,Caveolin-1 and HMGB-1 levels were all risk factors for the severity of sepsis in children(P<0.05).The combined diag-nosis of Caveolin-1 and HMGB-1 was significantly better than that of Caveolin-1(Z=2.109,P=0.035),HMGB-1(Z=2.099,P=0.036),PCT(Z=2.487,P=0.013),hs-CRP(Z=2.419,P=0.016)and TNF-α(Z=3.441,P=0.001)were diagnosed alone.Compared with simple sepsis group,cerebrospinal fluid Caveo-lin-1 and HMGB-1 levels in sepsis complicated with purulent meningitis group were significantly increased,and the difference was statistically significant(P<0.05).The combined prediction of Caveolin-1 and HMGB-1 was significantly better than that of Caveolin-1(Z=2.621,P=0.009)and HMGB-1(Z=1.997,P=0.046)alone.Conclusion There are significant increases in the levels of Caveolin-1 and HMGB-1 in chil-dren with severe sepsis or sepsis complicated with purulent meningitis.Caveolin-1 and HMGB-1 have a certain clinical value in evaluating the severity of sepsis in children and predicting whether they are complicated with purulent meningitis.

Objective:To examine the prevalence of malnutrition and evaluate the impact of nutritional support on clinical outcomes in elderly patients diagnosed with gastric and colorectal cancer.Methods:A retrospective cohort study was conducted, analyzing elderly patients with gastrointestinal tumors who underwent surgical treatment in the general surgery department from January 2019 to June 2020.The Global Leadership Initiative on Malnutrition(GLIM)criteria were utilized to diagnose malnutrition, and the effects of malnutrition and nutritional support on clinical prognosis were investigated.Results:A total of 426 elderly hospitalized patients with gastric and colorectal tumors who underwent surgical treatment were included in this study.This cohort comprised 199 cases of gastric cancer and 227 cases of colorectal cancer, with ages ranging from 65 to 91 years(mean age: 72.05±5.99).According to the GLIM criteria, 43.7%(186/426)of the patients were diagnosed with malnutrition, of which 25.6%(109/426)were moderately malnourished and 18.1%(77/426)were severely malnourished.Among the gastric cancer patients, 73.4%(146/199)were identified as having nutritional risk, with 48.7%(97/199)being malnourished and 22.6%(45/199)experiencing severe malnutrition.In the colorectal cancer group, 63.9%(145/227)were at nutritional risk, 39.2%(89/227)were malnourished, and 14.1%(32/227)had severe malnutrition.Additionally, 60.3%(257/426)of the patients received nutritional support therapy: 25.4%(108/426)received parenteral nutrition(PN), 11.3%(48/426)received enteral nutrition(EN), 23.7%(101/426)received a combination of EN and PN, while 39.7%(169/426)did not receive any nutritional support.Regardless of the presence or degree of malnutrition, patients who received nutritional support had significantly shorter total hospital stays compared to those who did not receive nutritional support, and this difference was statistically significant( t=5.58, 3.69, 2.21, 3.03, all P<0.05). Conclusions:Providing nutritional support to malnourished patients can reduce the length of hospital stay and improve clinical outcomes.

Objective:To investigate the relationship between dynamic alterations in serum albumin (ALB) concentrations and clinical outcomes in hospitalized surgical patients, thus providing a basis for optimizing clinical management strategies.Methods:This study utilized data from a prospective observational cohort study on nutritional status among 7 122 elderly hospitalized patients across 34 tertiary hospitals in 18 Chinese cities. A total of 1 714 surgical patients hospitalized for 7-30 days with complete data were included. Standardized protocols were used to collect demographic data, clinical outcomes, and a range of laboratory results, including nutritional and hematological parameters. Heterogeneous effects of ALB on clinical outcomes were explored. Receiver operating characteristic (ROC) curves were used to determine cutoff values for infection-related complications. Correlation analyses and multiple linear regression models were used to identify independent predictors of the absolute change in ALB (?ALB).Results:Among the surgical patients, 69.7% (1 195/1 714) experienced a decline in ALB levels during their hospital stay, which was significantly associated with the occurrence of both infection- and non-infection-related complications. Simultaneously, a marked decrease in ALB was also significantly correlated with changes in nutritional and inflammatory status during hospitalization, worsening of gastrointestinal symptoms at discharge, and functional activity abnormalities (all P<0.05). ?ALB exhibited a close association with outcome variables such as infection-related complications. Based on the incidence of infection-related complications, a cutoff value for ALB was calculated, dividing patients into a high-risk group ( n=179) and a low-risk group ( n=1 535), and a statistically significant difference in the incidence of infection-related complications was found between these two groups ( P<0.05). Correlation analysis and multiple linear regression modeling revealed that female gender, a higher baseline ALB level, a poorer baseline inflammatory status, an exacerbation of inflammatory status, larger alterations in platelet-to-lymphocyte ratio, and the presence of infection-related complications were predictive factors for a decline in ALB levels among surgical patients during their hospital stay. Conclusions:?ALB serves as a critical indicator of the inflammatory-nutritional interplay, with its magnitude of decline effectively predicting clinical outcomes and nutritional status changes and guiding multidisciplinary interventions in surgical patients.

Objective To investigate the effect of acupuncture at key muscle movement points combined with exercise training on neurophysiological indicators,muscle tone and quality of life in patients with spinal cord injury(SCI).Methods Eighty SCI patients admitted to the Rehabilitation Diagnosis and Treatment Center of Beijing Rehabilitation Hospital Affiliated to Capital Medical University from September 2022 to June 2024 were selected.Patients were divided into the control group(receiving routine acupuncture combined with exercise training,40 cases)and the observation group(receiving acupuncture combined with exercise training at key muscle movement points,40 cases)according to the random number table method.The neurophysiological indicators[motor nerve conduction velocity(MNCV),sensory nerve conduction velocity(SNCV)],limb function[Fugl-Meyer Assessment(FMA),Modified Ashworth Scale(MAS)]and quality of life[Barthel index,functional independence measure(FIM)]were compared between the two groups.Results After intervention,the MNCV and SNCV of median nerve,ulnar nerve,tibial nerve and common peroneal nerve were increased in the observation group than those in the control group(P＜0.05).After intervention,there were higher FMA scores,Barthel index and FIM scores in the observation group than those of the control group,while the MAS score was lower than that of the control group(P＜0.05).Conclusion Acupuncture at key muscle movement points combined with exercise training can effectively improve the neuroelectrophysiological indicators,limb functions and quality of life of SCI patients,which is feasible rehabilitation intervention program.

Objective:To explore the clinical manifestations and genetic basis for a rare case of Generalized arterial calcification of infancy (GACI).Methods:A 44-day-old female infant who was treated at Baoding Hospital of Beijing Children′s Hospital Affiliated to Capital Medical University on August 26, 2022 was selected as the study subject. Clinical data of the child was collected, and Trio-whole exome sequencing (Trio-WES), whole genome copy number variation sequencing (CNV-seq) and minigene splicing assay were carried out to analyze the pathogenicity of the variants.Results:The child had presented with fever and high inflammatory indicators, for which treatment with various antibiotics was ineffective. Ultrasound had revealed extensive arterial calcification and arterial wall thickening. The child was suspected for GACI with arteritis related to the primary disease. Her fever was relieved by treatment with glucocorticoid and biological agents. Trio-WES revealed that she has harbored compound heterozygous variants of the ABCC6 gene, namely c. 4404-1G>A and c. 4041+ 5G>T, for which the latter was unreported previously. Based on the guidelines from the American College of Medical Genetics and Genomics, the variants were classified as likely pathogenic (PVS1+ PM2_Supporting) and variant of unknown significance (PM2_Supporting+ PM3+ PP3), respectively. The result of CNV-seq was negative. And the minigene splicing assay has further verified that both variants can result in alternative splicing. Conclusion:For pyrexia with unknown causes and refractory to conventional treatment, it is necessary to recommend early genetic testing to avoid missed diagnosis of GACI.

Objective:To analyze the clinical effect of low-frequency repetitive transcranial magnetic stimulation(rTMS)combined with neuromuscular joint facilitation(NJF)technique in improving the enhancement of muscle tone after stroke.Methods:From October 2020 to October 22,a total of 114 patients with increased muscle tone at lower limb during the recovery period of stroke who admitted to Beijing Rehabilitation hospital were selected,and they were randomly divided into the observation group(57 cases)and the control group(57 cases)according to the random number table method.The control group received routine rehabilitation treatment.The observation group added low-frequency rTMS and NJF training on the basis of the routine rehabilitation treatment.The differences of clinical efficacy and various indicators of muscle tone of lower limb before and after treatment between two groups were compared,which included modified Ashwonh score(MAS)scale,functional ambulation category(FAC)scale of the motor of lower limb,Fugl-Meyer motor function scale-Lower limbs(FMA-L),clinical spasmodic index(CSI),modified Barthel index(MBI)of activity ability of daily life,integrated electromyogram(IEMG)and root mean square(RMS)of tibialis anterior muscle of lower limb in electromyogram.Results:After intervention,29 cases appeared significant effect,and 23 cases appeared valid result,and 5 cases appeared invalid result in the observation group,and 20 cases appeared significant effect,and 20 cases appeared valid result,and 17 cases appeared invalid result in the control group.The total effective rate of the observation group was 91.23%,which was significantly higher than 70.18%of the control group,and the difference was statistically significant(x2=8.111,P<0.05).Before intervention,there was no statistically significant difference in each indicator between the two groups(P>0.05).The MAS score,CSI score,IEMG and RMS of two groups after intervention were significantly lower than those before intervention,while the FAC score,FMA-L score and MBI score were significantly higher than those before intervention,and the differences were significant(t=3.377,4.398,5.554,P<0.05),respectively.At the same time,the MAS score,CSI score,IEMG and RMS of the observation group were significantly higher than those of the control group,and the differences were statistically significant(t=11.160,9.625,16.993,8.095,P<0.05),respectively.Conclusion:The combined application of low-frequency rTMS and NJF training can significantly improve the enhancement of muscle tone after stroke,and effectively reduce the muscle tone of lower limb,and improve the motor function of lower limb and the degree of spasticity,and improve the activity ability of daily life.

Most hospitalized patients infected with coronavirus disease 2019 (COVID-19) are in severe or critical condition, and malnutrition is a key factor contributing to adverse outcomes. The basic principles of medical nutrition therapy have been determined in the recently released tenth edition of the National Diagnosis and Treatment Protocol. The principles have promoted nutritional risk assessment, emphasized the preferred method of enteral nutrition, and recommended the daily intake of calories at 25 to 30 kcal/kg and protein at > 1.2g/kg. Parenteral nutrition should be also added when necessary. Based on the above principles, Beijing Hospital has refined the medical nutrition therapy measures to facilitate the implementation in clinical practice, in order to improve healthcare quality and decrease the mortality in COVID-19 patients.
