OBJECTIVE To construct a predictive model for evaluating the efficacy of a triple antiemetic regimen (neurokinin- 1 receptor antagonist+5-hydroxytryptamine 3 receptor antagonist+dexamethasone) for preventing nausea and vomiting induced by highly emetogenic chemotherapy (HEC) based on interpretable deep learning algorithms. METHODS Clinical data of cancer patients who received HEC and were treated with the standard triple antiemetic regimen in the oncology department of Tianjin Medical University General Hospital from January 2018 to December 2022 were collected retrospectively. Demographic, clinical and metabolism-related variables were integrated. After data pre-processing, two deep learning algorithms (deep random forest and dense neural network) and four machine learning algorithms (support vector machine, categorical boosting, random forest and decision tree) were used to build predictive models. Subsequently, model performance evaluation and model interpretability analysis were conducted. RESULTS Among the six candidate models, the deep random forest model demonstrated the best predictive performance on the test set, with an area under the receiver operating characteristic curve of 0.850, an accuracy of 0.911, a precision of 0.805, a recall of 0.783, an F1 score of 0.793, and a Brier score of 0.075. Interpretability analysis revealed that creatinine clearance rate (Ccr) was the key predictive factor, and low Ccr levels, female gender, younger age, highly emetogenic drugs (particularly cisplatin-containing chemotherapy regimens), and anticipatory nausea and vomiting were positively correlated with the risk of HEC-related nausea and vomiting. CONCLUSIONS The deep random forest model exhibits the best performance in predicting the efficacy of triple antiemetic regimen for preventing HEC-related nausea and vomiting. The key predictors in this model primarily include Ccr,anticipatory nausea and vomiting, gender, age, and highly emetogenic drugs.

Objective To investigate the probability and dosimetric risk factors of lung injury after sequential immune checkpoint inhibitors (ICIs) and thoracic radiotherapy. Methods A retrospective analysis was conducted on 139 patients who received sequential ICIs and thoracic radiotherapy in Xuzhou Cancer Hospital and Affiliated Hospital of Xuzhou Medical University between February 2020 and February 2024. The relationships of clinical factors and lung and heart volume dose parameters with grade ≥ 2 acute lung injury (ALI) in patients with thoracic tumors were studied using univariable (χ2 test, t test, nonparametric test) and multivariable (binary logistic regression analysis) methods. The thresholds of dosimetric risk factors were determined using the receiver operating characteristic curves. Clinical factors included age, gender, smoking history, type of ICIs, cycle of ICI application, and the interval between ICI application and thoracic radiotherapy. Dose parameters included total radiotherapy dose, single dose, planning target volume, maximum dose of planning target volume, average dose of planning target volume, total lung volume, heart volume, and the V5, V10, V15, V20, V25, V30, V35, and V40 of lung and heart. Results The incidence of grade ≥ 2 ALI in the included cases was 36% (50/139). The χ2 test did not find any statistically significant clinical factors. In the univariable and binary Logistic regression analysis, lung V15 and V20, heart V15 and V20, and lung volume were independent risk factors for the occurrence of grade ≥ 2 ALI in sequential ICIs and thoracic radiotherapy. The thresholds were 18.51% for lung V15, 14.43% for lung V20, 32.41% for heart V15, and 17.74% for heart V20. Conclusion For patients who are going to receive thoracic radiotherapy after ICIs, the thresholds of lung V15 and V20 and heart V15 and V20 in the radiotherapy plan are recommended to be less than 18.51%, 14.43%, 32.41%, and 17.74%, respectively, which can effectively reduce the occurrence of grade ≥ 2 ALI.

The phase changes and quantity-quality transfer of 17 batches of Ostreae Concha(Ostrea rivularis) during the raw material-calcined decoction pieces-standard decoction process were analyzed. The content of calcium carbonate(CaCO_3), the main component, was determined by chemical titration, and the extract yield and transfer rate were calculated. The CaCO_3 content in the raw material, calcined decoction pieces, and standard decoction was 94.39%-98.80%, 95.03%-99.22%, and 84.58%-90.47%, respectively. The process of raw material to calcined decoction pieces showed the yield range of 96.85% to 98.55% and the CaCO_3 transfer rate range of 96.92% to 99.27%. The process of calcined decoction pieces to standard decoction showed the extract yield range of 2.86% to 5.48% and the CaCO_3 transfer rate range of 2.59% to 5.13%. The results of X-ray fluorescence(XRF) assay showed that the raw material, calcined decoction pieces, and standard decoction mainly contained Ca, Na, Mg, Si, Br, Cl, Al, Fe, Cr, Mn, and K. The chemometric results showed an increase in the relative content of Cr, Fe, and Si from raw material to calcined decoction pieces and an increase in the relative content of Mg, Al, Br, K, Cl, and Na from calcined decoction pieces to standard decoction. X-ray diffraction(XRD) was employed to establish XRD characteristic patterns of the raw material, calcined decoction pieces, and standard decoction. The XRD results showed that the main phase of all three was calcite, and no transformation of crystalline form or generation of new phase was observed. Fourier transform infrared spectroscopy(FTIR) was employed to establish the FTIR characteristic spectra of the raw material, calcined decoction pieces, and standard decoction. The FTIR results showed that the raw material had internal vibrations of O-H, C-H, C=O, C-O, and CO■ groups. Due to the loss of organic matter components after calcination, no information about the vibrations of C-H, C=O, and C-O groups was observed in the spectra of calcined decoction pieces and standard decoction. In summary, this study elucidated the quantity-quality transfer and phase changes in the raw material-calcined decoction pieces-standard decoction process by determining the CaCO_3 content, calculating the extract yield and transfer rate, and comparing the element changes, FTIR characteristic spectra, and XRD characteristic pattern. The results were reasonable and reliable, laying a foundation for the subsequent process research and quality control of the formula granules of calcined Ostreae Concha(O. rivularis Gould), and providing ideas and methods for the quality control of the whole process of raw material-decoction pieces-standard decoction-formula granules of Ostreae Concha and other testacean traditional Chinese medicine.

ObjectiveTo observe the effect of modified Tianwang Buxindan (MTBD) on the skin of sleep-deprived (SD) mice and investigate its mechanism. MethodSixty 2-month-old female Kunming mice were randomly divided into a blank group, a model group, a vitamin C (VC, 0.08 g·kg-1), and MTBD low-, medium-, and high-dose groups (6.5, 12.5, 25 g·kg-1). Except for the blank group, the other groups were subjected to SD mouse model induction (using multiple platform water environment method for 18 hours of sleep deprivation daily from 15:00 to next day 9:00), continuously for 14 days, and caffeine (CAF, 7.5 mg·kg-1) was injected intraperitoneally from the 2nd week onwards, continuously for 7 days. While modeling, the blank group and the model group were administered with normal saline (0.01 mL·g-1), and the other groups received corresponding drugs for treatment. On the day of the experiment, general observations were recorded (such as body weight, spirit, fur, and skin). After sampling, skin tissue pathological changes were observed under an optical microscope using hematoxylin-eosin (HE) and Masson staining methods. Skin thickness and skin moisture content were measured. Biochemical assay kits were used to detect skin hydroxyproline (HYP) content, skin and serum superoxide dismutase (SOD) activity, and malondialdehyde (MDA) content. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum interleukin (IL)-6, tumor necrosis factor (TNF)-α, and IL-1β levels in mice. Western blot was used to detect skin tissue type Ⅰ collagen (ColⅠ), type Ⅲ collagen (ColⅢ), phosphatidylinositol 3-kinase (PI3K), phosphorylated (p)-PI3K, protein kinase B (Akt), p-Akt, nuclear factor E2-related factor 2 (Nrf2), heme oxygenase (HO)-1, and nuclear factor (NF)-κB protein expression. ResultCompared with the blank group, the model group showed varying degrees of changes. In general, signs of aging such as reduced body weight (P<0.01), listlessness, dull fur color, and formation of wrinkles on the skin appeared. Tissue specimen testing revealed skin thinning, flattening of the dermoepidermal junction (DEJ), and reduced collagen fibers under the optical microscope. Skin thickness and moisture content decreased, skin tissue HYP content significantly decreased (P<0.01), skin and serum SOD activity significantly decreased (P<0.01), and MDA content significantly increased (P<0.01). Serum IL-6, TNF-α, and IL-1β levels significantly increased (P<0.01). Skin ColⅠ, ColⅢ, p-PI3K/PI3K, p-Akt/Akt, Nrf2, and HO-1 protein expression significantly decreased (P<0.05, P<0.01), and NF-κB expression increased (P<0.01). Compared with the model group, the VC group and the MTBD low-dose group showed increased skin moisture content, HYP content, SOD activity, and ColⅠ, ColⅢ, p-PI3K/PI3K protein expression (P<0.05, P<0.01), and decreased serum MDA content (P<0.05). In addition, a decrease in serum IL-6 and IL-1β levels was detected in the MTBD low-dose group (P<0.05), while the above indicators in the MTBD medium- and high-dose groups improved (P<0.05, P<0.01). ConclusionSleep deprivation accelerates the aging process of the skin in SD model mice. MTBD can improve this phenomenon, exerting anti-inflammatory and antioxidant effects, and its mechanism of action may be related to the activation of the PI3K/Akt/Nrf2 signaling pathway.

Objective To investigate the risk factors for bronchopulmonary dysplasia (BPD) in preterm infants,and to establish a risk prediction model. Methods A total of 120 preterm infants who were admitted to the neonatal intensive care unit of Shanghai Children's Hospital from January to December 2022 were included. According to the diagnostic criteria for BPD released by the National Institute of Child Health and Human Development in 2018,they were divided into a non-BPD group (84 infants) and a BPD group (36 infants). The clinical data of the infants and their mothers were compared between the two groups. The univariate analysis and the stepwise multivariate regression analysis were used to identify the risk factors for BPD and establish a risk prediction model. Results The results showed that a gestational age of<28 weeks,duration of noninvasive respiratory support,comorbidity with infectious pneumonia,and chorioamnionitis in the mother were independent risk factors for BPD in preterm infants (P<0.05). A nomogram model for predicting the development of BPD was established based on the risk factors,with an area under the receiver operating characteristic curve of 0.93,and the calibration curve of this nomogram had a slope of about 1. The goodness-of-fit test indicated the model fitted well (x2=8.287,P=0.406). Conclusions A gestational age of<28 weeks,duration of noninvasive respiratory support,comorbidity with infectious pneumonia,and chorioamnionitis in the mother are independent risk factors for BPD in preterm infants.

Objective:To summarize the clinical and genetic characteristics of early-onset spinocerebellar ataxia type 5 (SCA5) caused by SPTBN2 gene mutation. Methods:The clinical and genetic data of a child with early-onset SCA5 diagnosed in the Department of Children′s Rehabilitation, Women and Children′s Hospital Affiliated to Qingdao University in February 2022 were retrospectively analyzed. The literatures related to early-onset SCA5 in major databases at home and abroad were retrieved and summarized.Results:The patient, a 4 years and 1 month old girl, was admitted to hospital because of "unable to stand independently at 2 years and 3 months", primarily presented with developmental delay, ataxia, hypotonia, and tendon hyperreflexia during infancy. Progressive cerebellar atrophy was observed on brain magnetic resonance imaging. A de novo heterozygous mutation of the SPTBN2 c.793G>C(p.Asp265His) was identified in the patient. Following hospitalization, the child received comprehensive rehabilitation therapy encompassing physical, occupational, language, educational interventions as well as bicycle ergometer training and transcranial magnetic stimulation. The patient was followed-up for more than 1 year to 4 years and 1 month old, whose motor function, cognitive abilities, and language skills were improved to some extent. A total of 13 English articles and 1 Chinese article were retrieved from the databases. A total of 20 early-onset SCA5 patients have been reported, with onset ages all within 12 months. Infants exhibited decreased muscle tone and delayed motor milestones, with the main clinical manifestations of ataxia, generalized developmental delay, and cerebellar atrophy. The previously reported cases involved 11 mutation sites in the SPTBN2 gene, and the main types of mutations were de novo missense mutations. The mutation site in this case has not been reported in the previous literature. Conclusions:Early-onset SCA5 is a rare autosomal dominant disorder caused by heterozygous mutations in the SPTBN2 gene. The main clinical manifestations include ataxia from infancy, developmental retardation and cerebellar atrophy. Early rehabilitation intervention can improve the degree of the dysfunction.

The patient was a 55-year-old man. On February 16, 2024, he was admitted to Peking Union Medical College Hospital complaining of "weakness and poor appetite for more than half a year, and found creatinine increase for 1 week". The patient was diagnosed with multiple myeloma. During the treatment in our hospital, the patient sustained"hyponatremia"(Na 124-136 mmol/L measured by indirect ion selective electrode method), and combined with the patient′s clinical symptoms and serum osmotic pressure results (327 mOsm/kg H 2O), it was considered that hyperglobulinemia led to pseudohyponatremia. So no intervention was given. Subsequent failure to recognize pseudohyponatremia during treatment in other hospitals and the administration of hypertonic saline resulted in severe iatrogenic hypernatremia. By reviewing similar cases in our hospital, we found that hyperglobulinemia/hyperlipidemia associated pseudohyponatremia was not uncommon. This case reminds us that for patients whose serum solid phase ratio is higher than normal due to various reasons, the use of indirect ion selective electrode method to determine serum sodium is prone to false low, and direct ion selective electrode method can be used to re-test blood sodium to determine whether it is true, so as to avoid iatrogenic injury to patients.
