Objective To explore the nutritional risk investigation and influencing factors of elderly patients with community-acquired pneumonia (CAP). Methods The clinical data of 239 elderly patients with CAP in Western Theater General Hospital were retrospectively analyzed from January 2022 to January 2024. Nutritional risk screening scale (NRS2002) was used to investigate the nutritional risk of patients. According to the nutritional risk investigation results, 239 elderly patients with CAP were divided into higher risk group (NRS2002≥3 points) and lower risk group (NRS2002<3 points). Univariate analysis was used to compare the gender, age, education level, body mass index (BMI), family monthly income, living condition, severity of pneumonia, smoking history, presence or absence of chronic diseases, cognitive dysfunction and self-care ability. The independent risk factors of nutritional risk in elderly patients with CAP were analyzed by binary logistic regression analysis. Results According to NRS2002 score, there were 87 cases (36.4%) in higher risk group and 152 cases (63.6%) in lower risk group. The NRS2002 scores in higher risk group were significantly higher than those in lower risk group (P<0.05). There were no obvious differences in gender, BMI, family monthly income and presence or absence of smoking history between groups (P>0.05). The higher risk group had significantly higher rates of age>70 years old, education level (high school and below), living condition (living alone), severity of pneumonia (high-risk pneumonia), chronic disease, cognitive dysfunction and poor self-care ability than the lower risk group (P<0.05). Binary logistics regression analysis showed that age>70 years old , education level of high school and below, living condition (living alone), severity of pneumonia (high-risk pneumonia), chronic diseases, cognitive dysfunction and self-care ability (poor) were independent risk factors for nutritional risk in elderly CAP patients (P<0.05). Conclusion Elderly patients with CAP have high nutritional risk, which may be affected by many factors such as age, education level, living condition, severity of pneumonia, presence or absence of chronic diseases, cognitive dysfunction and self-care ability. It is necessary to formulate targeted intervention measures according to the above factors to improve the nutritional risk of patients.

Purpose::To identify the risk factors for training-related lower extremity muscle injuries in young males by a non-invasive method of body composition analysis.Methods::A total of 282 healthy young male volunteers aged 18 -20 years participated in this cohort study. Injury location, degree, and injury rate were adjusted by a questionnaire based on the overuse injury assessment methods used in epidemiological studies of sports injuries. The occurrence of training injuries is monitored and diagnosed by physicians and treated accordingly. The body composition was measured using the BodyStat QuadScan 4000 multifrequency Bio-impedance system at 5, 50, 100 and 200 kHz to obtain 4 impedance values. The Shapiro-Wilk test was used to check whether the data conformed to a normal distribution. Data of normal distribution were shown as mean ± SD and analyzed by t-test, while those of non-normal distribution were shown as median (Q 1, Q 3) and analyzed by Wilcoxon rank sum test. The receiver operator characteristic curve and logistic regression analysis were performed to investigate risk factors for developing training-related lower extremity injuries and accuracy. Results::Among the 282 subjects, 78 (27.7%) developed training injuries. Lower extremity training injuries revealed the highest incidence, accounting for 23.4% (66 cases). These patients showed higher percentages of lean body mass ( p = 0.001), total body water (TBW, p=0.006), extracellular water ( p=0.020) and intracellular water ( p=0.010) as well as a larger ratio of basal metabolic rate/total weight ( p=0.006), compared with those without lower extremity muscle injuries. On the contrary, the percentage of body fat ( p=0.001) and body fat mass index ( p=0.002) were lower. Logistic regression analysis showed that TBW percentage > 65.35% ( p=0.050, odds ratio =3.114) and 3rd space water > 0.95% ( p=0.045, odds ratio =2.342) were independent risk factors for lower extremity muscle injuries. Conclusion::TBW percentage and 3rd space water measured with bio-impedance method are potential risk factors for predicting the incidence of lower extremity muscle injuries in young males following training.

PURPOSE:
The long-term situation of children with spinal cord injury (SCI) was investigated, and suggestions for helping them better return to the society were provided.
METHODS:
SCI patients less than 18 years old hospitalized in Beijing Boai Hospital from January 2011 to December 2020 were retrospectively analyzed. Information including motor function, complications, characteristic changes, self-care abilities, school attendance and social participation were collected by telephone interview and electronic questionnaire. All the answers were statistically analyzed.
RESULTS:
A total of 86 cases were enrolled, 77 girls and 9 boys, with a median injury age of 6 years and 2 months. The follow-up time was 3-130 months. The main cause of trauma in these children was sport injury (66.3%), the thoracic spinal cord was involved the most (91.9%), and complete SCIs accounted for the majority (76.7%). In terms of complications, children with complete SCIs were more likely to have urinary incontinence, constipation and characteristic changes (p < 0.05); whereas the incomplete SCIs often have spasticity (p < 0.05). As to the daily living abilities, children with incomplete lumbar SCIs were more capable to accomplish personal hygiene, transfer, and bathing independently than those with complete injuries, or cervical/thoracic SCIs, respectively (p < 0.05). Moreover, children older than 9 years care more able to dress and transfer independently than the youngers (p < 0.05). Wheelchair users accounted for 84.9% and more than half of them were able to propel wheelchair independently, and those who move passively in wheelchairs were mostly introverted kids (p < 0.05). Almost all (93.8%) children with incomplete injuries were able to walk independently. Most (79.1%) children continued to attending school, and 41.9% participated in interest classes. Unfortunately, 67.4% of the children spent less time playing with their peers than before the injury.
CONCLUSION
SCIs impair physical structures and function of children, affect their independence in daily living, and restrict school attendance and social interaction. Comprehensive rehabilitation after injury is a systematic work. Medical staff and caregivers should not only pay attention to neurological function, but also help them improve self-care abilities. It is also important to balance rehabilitation training and school work and social participation.

Objective: To analyze the clinical characteristics and complications of esophageal foreign bodies of button battery ingestion in children. Methods: A retrospective descriptive study included 83 children who were hospitalized in our hospital on account of button battery ingestion from January 2011 to December 2021. There were 50 males (60.2%) and 33 females (39.8%). The age ranged from 7.6 months to one month off 10 years, with a median age of 18 months. The data of patient demographics and time from ingestion to admission, location, symptoms, management, complications, and follow-up outcome were recorded. SPSS17.0 software was used for statistical analysis. Results: Seventy-two children (86.7%) were younger than 3 years old. The time from ingestion to admission ranged from 1 h to 2 months, with a median time of 8 h. Among the 63 children who were first diagnosed in our hospital, the most common clinical symptoms were nausea and vomiting (32 cases, 50.8%), dysphagia (31 cases, 49.2%), salivation (11 cases, 17.5%) and fever (10 cases, 15.9%). Seventy-three of 83 cases had complete preoperative diagnostic tests, and 55 cases (75.3%) were diagnosed by X-ray. In 56 cases (76.7%), the foreign badies were impacted in the upper third of esophagus. In 72 cases (86.7%), the foreign badies were removed by rigid esophagoscopy. 23 (27.7%) had serious complications, including tracheoesophageal fistula in 15 cases(TEF;65.2%), vocal cord paralysis (VCP;34.8%) in 8 cases, esophageal perforation in 3 cases (EP;13.0%), hemorrhage in 3 cases(13.0%), mediastinitis in 3 cases (13%), and periesophageal abscess in 1 case (4.3%). There were significant differences in the exposure time of foreign bodies and unwitnessed ingestion by guardians in the complications group (P<0.05). 2 cases died (2.4%)respectively due to arterial esophageal fistula bleeding and respiratory failure caused by stent displacement during the treatment of tracheoesophageal fistula. Conclusion: Accidental button battery ingestion can be life-threatening. and it mostly happens in children under 3 years old. Serious complications may happen cause of non-specific clinical manifestations and unwitnessed ingestions. Anterior and lateral chest X-ray is the first examination choice. Tracheoesophageal fistula is the most common serious complication.

ObjectiveTo predict the potential targets and mechanism of Jingfang mixture in the treatment of H1N1 influenza and provide references for clinical application of Jingfang mixture. MethodThe active components and targets of Jingfang mixture against H1N1 influenza were screened out by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP),SwissTargetPrediction, and TargetNet. The targets of H1N1 influenza were obtained from GeneCards,Online Mendelian Inheritance in Man (OMIM), and DisGeNET and standardized by UniProt KB. The intersection targets were obtained by Venny 2.1.0. The "drug-component-target" network was constructed with Cytoscape 3.2.1 and analyzed for the topological attributes. The intersection targets were uploaded to STRING 11.5 to obtain the protein-protein interaction (PPI) network. Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were carried out by Metascape. Finally,the top active components ranked by degree were docked to the core targets by Autodock vina and visually analyzed by PyMOL. Balb/c female rats were used for experimental verification. Hematoxylin-eosin(HE) staining was used to observe the pathological changes in lung tissues. Enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of tumor necrosis factor-α(TNF-α),interleukin-10(IL-10), and interleukin-17(IL-17). Real-time fluorescence-based quantitative polymerase chain reaction(Real-time PCR) and Western blot were used to detect the mRNA and protein expression levels in lung tissues. ResultThere were 144 active components in Jingfang mixture. A total of 421 target genes of Jingfang mixture and 2 956 targets of H1N1 influenza were identified,including 199 common targets. Topological analysis showed that the core components of Jingfang mixture against H1N1 influenza included quercetin,luteolin, and kaempferol,and the core targets included prostaglandin-endoperoxide synthase 2(PTGS2),estrogen receptor alpha(ESR1),inducible nitric oxide synthase 2(iNOS2),peroxisome proliferator-activated receptorγ(PPARγ),and cyclooxygenase-1(PTGS1). GO enrichment yielded 697 items in biological process (BP) (P<0.01), 59 items in molecular function (MF)(P<0.01), and 21 items in cellular component (CC) (P<0.01). A total of 132 signaling pathways (P<0.01) were obtained by KEGG enrichment analysis, including phosphatidylinositol 3-kinases(PI3K)/protein kinase B(Akt) signaling pathway and mitogen-activated protein kinase(MAPK) signaling pathway,most of which were related to the regulation of immune inflammation. Molecular docking showed that the binding energy of the active components of Jingfang mixture to the core targets was less than -5.0 kcal·mol-1,indicating good binding activity. HE staining showed that the lung tissues were significantly improved after drug intervention,and Real-time PCR and Western blot showed that Jingfang mixture could reduce the mRNA and protein expression of PI3K and Akt in lung tissues. ConclusionJingfang mixture can play an anti-viral effect against the influenza A virus through multiple components,multiple targets, and multiple pathways. The active components quercetin,luteolin, and kaempferol may control the inflammation and regulate immunity on the PI3K/Akt,MAPK, and other signaling pathways by acting on targets such as PTGS2,ESR1,iNOS2,PPARγ, and PTGS1.

Corticosteroid switching can reverse abiraterone resistance in some patients with metastatic castration-resistant prostate cancer (mCRPC). Here, we investigated the potential biomarkers for predicting the efficacy of corticosteroid switching during treatment with abiraterone acetate (AA). We retrospectively analyzed 101 mCRPC patients receiving corticosteroid switching from West China Hospital and Sun Yat-Sen University Cancer Center between January 2016 and December 2018. All cases received AA plus prednisone as first-line therapy during mCRPC. Primary end points were biochemical progression-free survival (bPFS) and overall survival (OS). The risk groups were defined based on multivariate analysis. A total of 42 (41.6%) and 25 (24.8%) patients achieved 30% and 50% decline in prostate-specific antigen (PSA), respectively, after corticosteroid switching. The median bPFS and median OS on AA plus dexamethasone were 4.9 (95% confidence interval [CI]: 3.7-6.0) months and 18.8 (95% CI: 16.2-30.2) months, respectively. Aldo-keto reductase family 1 member C3 (AKR1C3) expression (hazard ratio [HR]: 2.15, 95% Cl: 1.22-3.80, P = 0.008) and baseline serum alkaline phosphatase (ALP; HR: 4.95, 95% Cl: 2.40-10.19, P < 0.001) were independent predictors of efficacy before corticosteroid switching in the multivariate analysis of bPFS. Only baseline serum ALP >160 IU l-1 (HR: 3.41, 95% Cl: 1.57-7.38, P = 0.002) together with PSA level at switch ≥50 ng ml-1 (HR: 2.59, 95% Cl: 1.22-5.47, P = 0.013) independently predicted poorer OS. Based on the predictive factors in multivariate analysis, we developed two risk stratification tools to select candidates for corticosteroid switching. Detection of serum ALP level, PSA level, and tissue AKR1C3 expression in mCRPC patients could help make clinical decisions for corticosteroid switching.

OBJECTIVES:
To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China.
METHODS:
A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups.
RESULTS:
Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05).
CONCLUSIONS
There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Journal of Experimental Hematology 2022;30(1):264-269
OBJECTIVE:
To evaluate the risk of reentry in HBV reactive blood donors and feasibility of HBV reentry strategy.
METHODS:
HBsAg+ or HBV DNA+ donors who had been quarantined for more than 6 months in Jiangsu Province could propose for reentry application. Blood samples were routinely screened by dual-ELISA for HBsAg, anti-HCV, HIV Ab/Ag, and anti- Treponema pallidum and those non-reactive ones were tested by minipool nucleic acid testing (NAT) for three times. To identify occult HBV donors, samples of NAT non-reactive were further tested by electrochemiluminescence immunoassay (ECLIA) for HBV seromarkers (including HBsAg, HBsAb, HBeAg, HBeAb, and HBcAb). Donors of only 4 ECLIA patterns were accepted to reentry, including all 5 HBV seromarkers negative, anti-HBs only but having history of hepatitis B vaccine injection, HBcAb only, HBsAb+ / HBcAb+ with HBsAb more than 200 IU/L. Additionally, the detection rate of HBV infection was compared between routine screening mode and ECLIA, as well as the reentry qualified rate of HBsAg+ and HBV DNA+ blood donors.
RESULTS:
From Oct. 2016 to Aug. 2019, a total of 737 HBV reactive donors had applied for reentry, including 667 HBsAg+ reactive and 70 HBV DNA+ reactive donors. Among 3 screening methods, the highest HBV detection rate (43.15%, 318/737) was observed on ECLIA, while only 4.75% (35/737) on ELISA and 3.12% (23/737) on NAT, respectively. Among 4 qualified patterns of HBV serological markers, the highest proportion was found in the all negative group (22.90%, 155/677), followed by the group with HBsAb+ only and history of hepatitis B vaccine injection (19.35%, 131/677), and the median concentration of HBsAb was 237.7 IU/L. The unqualified rate of HBV DNA+ donors was 82.86%, which was significantly higher than 47.98% of HBsAg+ donors.
CONCLUSION
Routine screening tests merely based on ELISA and NAT could miss occult HBV donors and may not be sufficient for blood safety. HBsAb concentration and vaccine injection history should be included in the evaluation of HBV reactive donors who intend to apply for reentry. There is a relatively larger residual risk of occult HBV infection in blood donors quarantined for HBV DNA reactive.
