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.

OBJECTIVES: To evaluate the clinical utility and translational potential of a remote jaundice monitoring system for home-based screening of neonatal hyperbilirubinemia. METHODS: A prospective self-controlled study was conducted, enrolling 538 newborns with gestational age ≥35 weeks, birth weight ≥2 000 g, and postnatal age ≤14 days at the Women's Hospital of Nanjing Medical University from March to October 2023. Four screening protocols with different predictive indicators were developed based on the Chinese Neonatal Transcutaneous Hourly Bilirubin Nomogram. The effectiveness of the system was evaluated, and the feasibility of using the remote jaundice monitoring system in actual home settings was analyzed. RESULTS: A total of 538 paired transcutaneous bilirubin (TcB) and total serum bilirubin (TSB) measurements showed a strong correlation (r=0.85, P<0.001), with 95.0% (511/538) of samples within the 95% limits of agreement. Using TcB ≥ the 95th percentile as the predictive indicator, the system achieved 100% sensitivity, 46.2% specificity, and an area under the receiver operating characteristic curve of 0.731 (95%CI: 0.682-0.780). This approach could reduce unnecessary hospital visits by 41.4% (221/538). CONCLUSIONS The system integrates the QBH-801 transcutaneous bilirubinometer, intelligent early warning, and remote guidance services, establishing a closed-loop "hospital-to-home" management model. It demonstrates high safety and feasibility, with significant clinical translational value.

BACKGROUND: Prior studies have shown that drivers with type 2 diabetes are more likely to be involved in motor vehicle collisions (MVCs) compared to the general population. Certain meteorological factors have been increasingly recognized as contributors to MVC risk. This study aims to examine the association of MVCs with temperature, rainfall, wind speed, and sunshine duration among drivers with type 2 diabetes. METHODS: Using Taiwan's National Health Insurance data (2019-2021), we identified individuals diagnosed with type 2 diabetes and linked their records to the Police-Reported Traffic Accident Registry to obtain daily MVC counts. Meteorological data were sourced from the Central Weather Administration. Associations between daily weather conditions and MVCs were assessed using a Distributed Lag Non-Linear Model. RESULTS: Over the 1,096-day study period, 170,468 MVC events involving drivers with type 2 diabetes were recorded. A U-shaped association was observed between same-day temperature and MVC rates. Compared with the reference temperature of 17.5 °C, both lower temperatures (≤15 °C; rate ratio [RR] = 1.014-1.053) and higher temperatures (≥30 °C; RR = 1.062) were associated with increased MVC risk. Rainfall showed an inverse relationship with MVCs. Compared with 70 mm of rainfall, the lowest MVC rate occurred at 129 mm (RR = 0.873), while the highest was on rain-free days (0 mm; RR = 1.068). Stronger effects were observed when lag periods up to 14 days were considered. Wind speed and sunshine duration were not significantly associated with MVC risk. CONCLUSIONS These findings suggest that drivers with type 2 diabetes should exercise greater caution on days with extreme temperatures or in days with lesser rainfall, as these conditions may elevate MVC risk.

OBJECTIVE: Hepatocellular carcinoma (HCC) is sensitive to ferroptosis, a new form of programmed cell death that occurs in most tumor types. However, the mechanism through which ferroptosis modulates HCC remains unclear. This study aimed to investigate the oncogenic role and prognostic value of FANCD2 and provide novel insights into the prognostic assessment and prediction of immunotherapy. METHODS: Using clinicopathological parameters and bioinformatic techniques, we comprehensively examined the expression of FANCD2 macroscopically and microcosmically. We conducted univariate and multivariate Cox regression analyses to identify the prognostic value of FANCD2 in HCC and elucidated the detailed molecular mechanisms underlying the involvement of FANCD2 in oncogenesis by promoting iron-related death. RESULTS: FANCD2 was significantly upregulated in digestive system cancers with abundant immune infiltration. As an independent risk factor for HCC, a high FANCD2 expression level was associated with poor clinical outcomes and response to immune checkpoint blockade. Gene set enrichment analysis revealed that FANCD2 was mainly involved in the cell cycle and CYP450 metabolism. CONCLUSION To the best of our knowledge, this is the first study to comprehensively elucidate the oncogenic role of FANCD2. FANCD2 has a tumor-promoting aspect in the digestive system and acts as an independent risk factor in HCC; hence, it has recognized value for predicting tumor aggressiveness and prognosis and may be a potential biomarker for poor responsiveness to immunotherapy.

Objective To compare the efficacy and safety between thermal ablation combined with synchronous transcatheter arterial chemoembolization(TACE)and TACE in patients with liver metastasis of neuroendocrine tumors of different pathologic grades.Methods A retrospective analysis was performed on patients with liver metastases of neuroendocrine tumors admitted to Department of Interventional Radiology,Zhongshan Hospital,Fudan University from Nov 1,2006 to Jul 31,2022.The patients were divided into synchronous ablation group and TACE group according to treatment mode and subgroups according to pathological grade.The lesions were evaluated by postoperative imaging examination.The patients were followed up until Jul 31,2023,and surgery-related complications were recorded.The endpoint of prognosis were progression-free survival(PFS)and overall survival(OS).Results A total of 86 patients with neuroendocrine tumor were collected,including 34 patients in simultaneous ablation group and 52 patients in TACE group.According to WHO classification,21 patients at G1 stage,45 patients at G2 stage and 20 patients at G3 stage were included.No serious postoperative complications occurred in all patients.The median OS was 47.0(95%CI:31.2-62.8)months in the TACE group and 56.0(95%CI:8.3-73.4)months in the synchronous ablation group,with no statistical difference between the two groups(P=0.50).The median PFS was 18.0(95%CI:6.0-30.0)months in the TACE group and 29.0(95%CI:10.0-48.0)months in the synchronous ablation group,with no statistical difference between the two groups(P=0.22).Of the 45 patients at G2 stage,27 received TACE with a median OS of 47.0 months,and 18 received synchronous ablation with a median OS of 59.0 months,and there was no statistical difference between the two groups(P=0.45).The median PFS was 12.0 months in the TACE group and 32.0 months in the synchronous ablation group,and the difference between the two groups was statistically significant(P=0.03).Conclusion Comparing with TACE,simultaneous ablation can delay disease progression in patients with liver metastasis of neuroendocrine tumors to a certain extent and has good safety,especially for patients with liver metastases of neuroendocrine tumors with intermediate or low grade.

Objective To study the intervention effect of narrative therapy on non-suicidal self-injury(NSSI),as well as anxiety and depression symptoms in adolescents with depressive disorder.Methods Sixty adolescents with depressive disorder and NSSI were randomly assigned to either the intervention group or the control group using coin flipping.The control group received conventional psychological support,while the intervention group received individual narrative therapy in addition to the conventional psychological support(twice a week,60 minutes per session,for a total of 3 weeks).Assessment of treatment efficacy was conducted using the Adolescent Self-Harm Questionnaire,Children's Depression Inventory,and Children's Anxiety and Mood Scale before the intervention,at the end of the intervention,and one month after the intervention for both groups.Results A total of 26 adolescents in the intervention group and 29 adolescents in the control group completed the entire study.At the end of the intervention and one month after the intervention,the intervention group showed a significant reduction in the NSSI frequency score,NSSI level,anxiety score,and depression score compared to before the intervention(P<0.017).Moreover,at the end of the intervention and one month after the intervention,the intervention group exhibited significantly lower NSSI frequency score,NSSI severity score,NSSI level,anxiety score and depression score compared to the control group(P<0.05).Conclusions Narrative therapy is effective in reducing NSSI frequency and alleviating NSSI severity,as well as anxiety and depression symptoms in adolescents with depressive disorder.[Chinese Journal of Contemporary Pediatrics,2024,26(2):124-130]

Objective To study the effects and mechanisms of tetramethylpyrazine(TMP)on tumor necrosis factor-α(TNF-α)-induced inflammatory injury in human coronary artery endothelial cells(HCAEC).Methods HCAEC were randomly divided into four groups:the control group(no treatment),the model group(treated with TNF-α,50 ng/mL for 24 hours),the TMP group(pre-treated with TMP,80 μg/mL for 12 hours followed by TNF-α treatment for 24 hours),and the SIRT1 inhibitor group(pre-treated with TMP and the specific SIRT1 inhibitor EX527 for 12 hours followed by TNF-α treatment for 24 hours).Cell viability was assessed using the CCK-8 method,lactate dehydrogenase(LDH)activity was measured using an LDH assay kit,reactive oxygen species(ROS)levels were observed using DCFH-DA staining,expression of pyroptosis-related proteins was detected by Western blot,and SIRT1 expression was analyzed using immunofluorescence staining.Results Compared to the control group,the model group showed decreased cell viability,increased LDH activity,ROS level and expression of pyroptosis-related proteins,and decreased SIRT1 expression(P<0.05).Compared to the model group,the TMP group exhibited increased cell viability,decreased LDH activity,ROS level and expression of pyroptosis-related proteins,and increased SIRT1 expression(P<0.05).In comparison to the TMP group,the SIRT1 inhibitor group showed decreased cell viability,increased LDH activity,ROS level and expression of pyroptosis-related proteins,and decreased SIRT1 expression(P<0.05).Conclusions TMP may attenuate TNF-α-induced inflammatory injury in HCAEC,which is associated with the inhibition of pyroptosis and activation of the SIRT1 signaling pathway.

Objective:To analyze the prognostic factors of children with septic shock in the pediatric intensive care unit.Methods:The clinical data of children diagnosed with septic shock in the pediatric intensive care unit of Guiyang Maternal and Child Health Hospital from April 2018 to April 2022 were retrospectively collected,and the children were divided into the death group and the survival group according to seven days regression.The basic data of the two groups were statistically compared，and the relationship between lactic acid，vasoactive-inotropic score one hour after admission，time of antibiotic initiation，serum potassium，serum sodium，serum calcium，serum troponin T，fluid resuscitation volume in the first hour，glutamyl aminotransferase，creatinine，total leukocyte count，C-reaction protein，brain natriuretic peptide were compared.The risk factors affecting the death of children were analyzed by Logistic regression.The relationship between fluid resuscitation volume in the first hour and prognosis was analyzed using the receiver operator characteristic (ROC) curve.Results:（1）A total of 67 children were included，19 died and 48 survived.（2）The first-hour liquid resuscitation dose in the survival group was lower than that in the death group，and the difference was statistically significant（ P<0.05）.（3）The ROC curve showed that the optimal cut-off of the first-hour liquid resuscitation dose was 25 mL/kg，with a sensitivity of 57.9% and a specificity of 72.9%.（4）In unifactorial analysis，lactic acid in the first hour of admission，early lactic acid after resuscitation，serum calcium，serum troponin T，alanine aminotransferase，combined septic encephalopathy，Glasgow coma score，and pediatric critical illness score were all risk factors for death in children within seven days（ P<0.05）.(5) Multivariate Logistic regression analysis showed that serum calcium（ OR=1.435， P=0.001）and lactic acid value after resuscitation（ OR=0.040， P=0.021）were independent risk factors for death in septic shock. Conclusion:The higher the total fluid resuscitation in the first hour，the higher the fatality rate.Serum calcium and early lactic acid after resuscitation are independent risk factors for death in children within seven days.
