Objective: To evaluate the recognition of acute respiratory infection (ARI) by a pretrained model based on electronic medical records (EMRs). Methods: 38 581 EMRs were obtained from Chongqing University Three Gorges Hospital in December 2021. Bidirectional encoder representation from transformers (BERT) pretrained model was used to identify ARI in EMRs. The results of medical professionals were considered as the gold standard to calculate the sensitivity, specificity, Kappa value, and area under the curve of the receiver operating characteristic (AUC). Results: There were 3 817 EMRs in the test set, with 1 200 ARIs. A total of 1 205 cases were determined as ARI by the model, with a sensitivity of 92.67% (1 112/1 200) and a specificity of 96.45% (2 524/2 617). The model identified ARI with similar accuracy in males and females (AUCs 0.95 and 0.94, respectively), and was more accurate in identifying ARI cases in those aged less than 18 than in adults 18-59 and adults 60 and older (AUCs 0.94, 0.89 and 0.94, respectively). The current model had a better identification of ARIs in outpatient patients than that in hospitalized patients, with AUCs of 0.74 and 0.95, respectively. Conclusion: The use of the BERT pretrained model based on EMRs has a good performance in the recognition of ARI cases, especially for the outpatients and juveniles. It shows a great potential to be applied to the monitoring of ARI cases in medical institutions.

INTRODUCTION:
A second-tier rapid response team (RRT) is activated for patients who do not respond to first-tier measures. The premise of a tiered response is that first-tier responses by a ward team may identify and correct early states of deterioration or establish goals of care, thereby reducing unnecessary escalation of care to the RRT. Currently, utilisation and outcomes of tiered RRTs remain poorly described.
METHODS:
A prospective observational study of adult patients (age ≥18 years) who required RRT activations was conducted from February 2018 to December 2019.
RESULTS:
There were 951 consecutive RRT activations from 869 patients and 76.0% patients had a National Early Warning Score (NEWS) ≥5 at the time of RRT activation. The majority (79.8%) of patients required RRT interventions that included endotracheal intubation (12.7%), point-of-care ultrasound (17.0%), discussing goals of care (14.7%) and intensive care unit (ICU) admission (24.2%). Approximately 1 in 3 (36.6%) patients died during hospitalisation or within 30 days of RRT activation. In multivariate analysis, age ≥65 years, NEWS ≥7, ICU admission, longer hospitalisation days at RRT activation, Eastern Cooperative Oncology Group performance scores ≥3 (OR [odds ratio] 2.24, 95% CI [confidence interval] 1.45-3.46), metastatic cancer (OR 2.64, 95% CI 1.71-4.08) and haematological cancer (OR 2.78, 95% CI 1.84-4.19) were independently associated with mortality.
CONCLUSION
Critical care interventions and escalation of care are common with second-tier RRTs. This supports the need for dedicated teams with specialised critical care services. Poor functional status, metastatic and haematological cancer are significantly associated with mortality, independent of age, NEWS and ICU admission. These factors should be considered during triage and goals of care discussion.

Patients with end-stage liver disease (ESLD) are often accompanied by various complications such as sarcopenia and cachexia including lipopenia, and it was believed in the past that such status was associated with malnutrition, while recent studies have shown that myostatin (MSTN) is associated with the progression of ESLD. MSTN can lead to sarcopenia and cachexia by affecting the metabolism of glucose, fat, and protein and the number of myocytes, and it can be used as a screening indicator for hepatocellular carcinoma (HCC) and an indicator for disease progression. Intervention via the MSTN pathway might be an effective method for controlling sarcopenia and cachexia in patients with ESLD, and MSTN may be an effective indicator for predicting the progression of liver cirrhosis to HCC.

OBJECTIVE:
To study the clinical features of catch-up growth of body height after kidney transplantation in children and related influencing factors.
METHODS:
A retrospective analysis was performed from the chart review data of 15 children who underwent kidney transplantation in Guangzhou Women and Children's Medical Center from July 2017 to November 2019. According to whether the increase in height standard deviation score (ΔHtSDS) in the first year after kidney transplantation reached ≥0.5, the children were divided into a catch-up group with 8 children and a non-catch-up group with 7 children. According to whether final HtSDS was ≥-2, the children were divided into a standard group with 6 children and a non-standard group with 9 children. The features of catch-up growth of body height and related influencing factors were compared between groups.
RESULTS:
The data showed that median ΔHtSDS was 0.8 in the first year after transplantation, which suggested catch-up growth of body height. There was a significant difference in HtSDS between the non-catch-up and catch-up groups (P<0.05). Baseline HtSDS before transplantation was positively correlated with HtSDS at the end of follow-up (r=0.622, P<0.05) and was negatively correlated with ∆HtSDS in the first year after transplantation (r=-0.705, P<0.05). Age of transplantation and mean dose of glucocorticoid (GC) per kg body weight were risk factors for catch-up growth after kidney transplantation (OR=1.23 and 1.74 respectively; P<0.05), while baseline HtSDS and use of antihypertensive drugs were independent protective factors for catch-up growth (OR=0.08 and 0.18 respectively; P<0.05); baseline HtSDS and ΔHtSDS in the first year after kidney transplantation were influencing factors for final HtSDS (β=0.984 and 1.271 respectively; P<0.05).
CONCLUSIONS
Kidney transplantation should be performed for children as early as possible, growth retardation before transplantation should be improved as far as possible, and multiple treatment methods (including the use of GC and antihypertensive drugs) should be optimized after surgery, in order to help these children achieve an ideal body height.

Objective To monitor the change patterns of the endemic situation of schistosomiasis in Tianmen City from 2015 to 2018, so as to provide the evidence for formulating the schistosomiasis control strategy in the city. Methods A total of 8 schistosomiasis surveillance sites were assigned in Tianmen City from 2015 to 2018, and the endemic situation of schistosomiasis and the related epidemiological factors were monitored. Results During the period from 2015 to 2018, a total of 15 983 local person-times and 3 629 mobile populations were detected for schistosomiasis using an indirect hemagglutination test (IHA) in Tianmen City, and the sero-prevalence was 0.88% to 1.44% and 0.96% to 2.39%, respectively; however, no egg-positives were identified. A total of 1 245 herd-times were detected, and no egg-positives were found in bovines. In addition, the areas of snail habitats were 116.69 to 117.23 hm2 and the mean densities of living snails were 0.07 to 0.17 snails/0.1 m2 during the study period; however, no infections were identified in snails. Conclusions The endemic situation of schistosomiasis appears low in Tianmen City; however, the factors related to schistosomiasis transmission remain in the city. The integrated strategy with emphasis on the control of infectious sources should be still intensified to consolidate the schistosomiasis control achievements.

Sperm DNA damage is recognized as an important biomarker of male infertility. To investigate this, sperm DNA damage was assessed by the sperm chromatin dispersion (SCD) test in semen and motile spermatozoa harvested by combined density gradient centrifugation (DGC) and swim-up in 161 couples undergoing in vitro fertilization (IVF). Semen analysis and sperm DNA damage results were compared between couples who did or did not achieve pregnancy. The sperm DNA damage level was significantly different between the two groups (P < 0.05) and was negatively correlated with IVF outcomes. Logistic regression analysis confirmed that it was an independent predictor for achieving clinical pregnancy. The effects of different levels of sperm DNA damage on IVF outcomes were also compared. There were significant differences in day 3 embryo quality, blastocyst formation rate, and implantation and pregnancy rates (P < 0.05), but not in the basic fertilization rate between the two groups. Thus, sperm DNA damage as measured by the SCD appears useful for predicting the clinical pregnancy rate following IVF.

OBJECTIVETo investigate whether emodin exerts protective effects on mouse with allergic asthma.
METHODSA mouse model of allergic airway inflflammation was employed. The C57BL/6 mice sensitized and challenged with ovalbumin (OVA) were intraperitoneally administered 10 or 20 mg/kg emodin for 3 days during OVA challenge. Animals were sacrificed 48 h after the last challenge. Inflammatory cell count in the bronchoalveolar lavage fluid (BALF) was measured. The levels of interleukin (IL)-4, IL-5, IL-13 and eotaxin in BALF and level of immunoglobulin E (IgE) in serum were measured with enzyme-linked immuno sorbent assay kits. The mRNA expressions of IL-4, IL-5, heme oxygenase (HO)-1 and matrix metalloproteinase-9 (MMP-9) were determined by real-time quantitative polymerase chain reaction.
RESULTSEmodin induced significant suppression of the number of OVA-induced total inflammatory cells in BALF. Treatment with emodin led to significant decreases in the levels of IL-4, IL-5, IL-13 and eotaxin in BALF and total IgE level in serum. Histological examination of lung tissue revealed marked attenuation of allergen-induced lung eosinophilic inflammation. Additionally, emodin suppressed IL-4, IL-5 and MMP-9 mRNA expressions and induced HO-1 mRNA expression.
CONCLUSIONEmodin exhibits anti-inflammatory activity in the airway inflammation mouse model, supporting its therapeutic potential for the treatment of allergic bronchial asthma.

OBJECTIVETo study the effects of post-discharge formula (PDF) for preterm infants, breast milk (BM) and term infant formula (TF) on increase rates of body weight, length and head circumference in preterm and low-birth-weight infants (PLBWIs) from discharge to 3 months after birth, and to provide a reference for the choice of feeding pattern for PLBWIs.
METHODSA total of 407 PLBWIs discharged from the newborn departments of ten hospitals in Guangzhou City and Foshan City in Guangdong Province, China were chosen for this study. According to feeding pattern, they were assigned to three groups: PDF-fed (n=258), BM-fed (n=58) and TF-fed (n=91). Their body weight, length and head circumference were measured at 3 months after birth, and the increase rates of growth indices relative to baseline values (at birth) were calculated and compared.
RESULTSAt 3 months after birth, the PDF-fed group had significantly greater body weight, length and head circumference than the BM-fed and TF-fed groups (P<0.05). The increase rates of body weight and length were significantly higher in the PDF-fed group than in the BM-fed and TF-fed groups (P<0.05).
CONCLUSIONSCompared with those fed with BM and TF after discharge, the PDF-fed PLBWIs have higher increase rates of body weight and length and show greater body weight and length at 3 months after birth. However, further study is needed to investigate the long-term effects.
