Lupus erythematosus (LE) is a spectrum of autoimmune diseases with complex and highly heterogeneous clinical manifestations. At one end of the spectrum lies cutaneous LE, which is limited to the skin, while at the other end is systemic LE (SLE) , which affects multiple organs and systems. The pathogenesis of LE involves the interplay of multiple factors, including genetic predisposition, environmental triggers, hormonal influences, and immune dysregulation. In recent years, emerging mechanisms such as metabolic reprogramming, mitochondrial dysfunction, and gut microbiota dysbiosis have provided new perspectives for understanding the pathogenesis of LE. Additionally, the discovery of novel biomarkers and the rapid development of artificial intelligence technologies have opened new avenues for early diagnosis and precise classification of LE. In terms of treatment, the introduction of biologic agents has marked a significant breakthrough in managing SLE patients who respond poorly to conventional therapies. However, LE research still faces multiple challenges, including incomplete understanding of its pathogenesis, difficulties in early diagnosis, and insufficient personalized treatment approaches. This article aims to provide a comprehensive review of the current status and major challenges in LE research, focusing on advances in elucidation of pathogenesis, discovery of biomarkers, as well as development of precision diagnostic tools and novel therapeutic strategies.

Objective:To develop a risk prediction model for identifying bronchopulmonary dysplasia (BPD) associated pulmonary hypertension (PH) in very premature infants.Methods:This was a retrospective cohort study. The clinical data of 626 very premature infants whose gestational age <32 weeks and who suffered from BPD were collected from October 1 st, 2015 to December 31 st, 2021 of the Seventh Medical Center of the People′s Liberation Army General Hospital as a modeling set. The clinical data of 229 very premature infants with BPD of Hunan Children′s Hospital from January 1 st, 2020 to December 31 st, 2021 were collected as a validation set for external verification. The very premature infants with BPD were divided into PH group and non PH group based on the echocardiogram after 36 weeks′ corrected age in the modeling set and validation set, respectively. Univariate analysis was used to compare the basic clinical characteristics between groups, and collinearity exclusion was carried out between variables. The risk factors of BPD associated PH were further screened out by multivariate Logistic regression, and the risk assessment model was established based on these variables. The receiver operating characteristic (ROC) area under curve (AUC) and Hosmer-Lemeshow goodness-of-fit test were used to evaluate the model′s discrimination and calibration power, respectively. And the calibration curve was used to evaluate the accuracy of the model and draw the nomogram. The bootstrap repeated sampling method was used for internal verification. Finally, decision curve analysis (DCA) to evaluate the clinical practicability of the model was used. Results:A total of 626 very premature infants with BPD were included for modeling set, including 85 very premature infants in the PH group and 541 very premature infants in the non PH group. A total of 229 very premature infants with BPD were included for validation set, including 24 very premature infants in the PH group and 205 very premature infants in the non PH group. Univariate analysis of the modeling set found that 22 variables, such as artificial conception, fetal distress, gestational age, birth weight, small for gestational age, 1 minute Apgar score ≤7, antenatal corticosteroids, placental abruption, oligohydramnios, multiple pulmonary surfactant, neonatal respiratory distress syndrome (NRDS)>stage Ⅱ, early pulmonary hypertension, moderate-severe BPD, and hemodynamically significant patent ductus arteriosus (hsPDA) all had statistically significant influence between the PH group and the non PH group (all P<0.05). Antenatal corticosteroids, fetal distress, NRDS >stage Ⅱ, hsPDA, pneumonia and days of invasive mechanical ventilation were identified as predictive variables and finally included to establish the Logistic regression model. The AUC of this model was 0.86 (95% CI 0.82-0.90), the cut-off value was 0.17, the sensitivity was 0.77, and the specificity was 0.84. Hosmer-Lemeshow goodness-of-fit test showed that P>0.05. The AUC for external validation was 0.88, and the Hosmer-Lemeshow goodness-of-fit test suggested P>0.05. Conclusions:A high sensitivity and specificity risk prediction model of PBD associated PH in very premature infants was established. This predictive model is useful for early clinical identification of infants at high risk of BPD associated PH.

Objective To explore the risk factors of apathy and correlations with cognitive function in patients with hypertension combined with cerebral small vessel disease(CSVD).Methods Totally 141 patients with hypertension combined with CSVD were prospectively enrolled and were divided into apathy group(n=43)and non-apathy group(n= 98)according to neuropsychiatric inventory-apathy scale(NPI-Apathy)scores.The general data,imaging marker scores and total imaging burden scores were compared between groups.In hypertension combined with CSVD patients,multivariate logistic regression analysis was performed to screen the independent risk factors of apathy,and Spearman correlation analysis was also performed to observe the correlation of apathy and cognitive function.Results The patients'age,high density lipoprotein cholesterol(HDL-C),Fazekas scores of lateral periventricular white matter hyper-intensity(WMH),cerebral microbleed of depth/infratentorial and total imaging burden scores of apathy group were all higher,while mini-mental state examination(MMSE)and Montreal cognitive assessment(MoCA)scores were both lower than those of non-apathy group(all P＜0.05).HDL-C and Fazekas scores of lateral periventricular WMH were both independent risk factors for apathy(both P＜0.05),while NPI-Apathy scores were moderately negatively correlated with cognitive function in patients with hypertension combined with CSVD(r=-0.543,-0.484,both P＜0.001).Conclusion HDL-C and Fazekas scores of lateral periventricular WMH were both independent risk factors for apathy in patients with hypertension combined with CSVD.The more severe the apathy,the lower the cognitive function.

Citri Reticulatae Pericarpium is a commonly used traditional Chinese medicine in China. By referring to herbal monographs and related research documents， and comparing all editions of Chinese Pharmacopoeia and local processing specifications， the processing history， modern processing specifications， study on chemical constituents and pharmacological effects before and after processing of Citri Reticulatae Pericarpium were summarized. It was found that the processing methods of Citri Reticulatae Pericarpium in the past dynasties were mainly cleansing， cutting and frying. The processing methods of Citri Reticulatae Pericarpium included in all editions of Chinese Pharmacopoeia were all cleansing and cutting. In modern local processing specifications， there were mainly processing methods such as frying， steaming and carbonizing. The components of Citri Reticulatae Pericarpium were mainly volatile oil and flavonoids. After processing， the total amount of volatile oil generally decreased， and the contents and compositions of volatile oil and flavonoids also changed. It may be the main reason for the difference of efficacy before and after processing. At present， the optimization of processing technology of Citri Reticulatae Pericarpium mainly focuses on steaming， processing with vinegar and baking. Pharmacological research on Citri Reticulatae Pericarpium mainly focuses on reducing blood lipid， relieving cough， relieving asthma and resolving phlegm， and inhibiting pulmonary fibrosis. The current research on the processing methods of Citri Reticulatae Pericarpium is not in-depth enough， the material basis of many processing methods has not been clarified， and the research on the efficacy before and after processing is not in-depth enough. Further research is needed to clarify the material basis and mechanism after the processing of Citri Reticulatae Pericarpium， so as to standardize the processing method and establish specific quality standards.

Objective? To explore the effects of WeChat combined with motivational interviewing in transitional care among young and middle-aged hypertension patients. Methods? By convenient sampling, we selected 129 young and middle-aged hypertension inpatients who were hospitalized in a classⅢ grade A hospital from June 2017 to March 2018 as subjects. All of the patients were randomly divided into observation group (n=66) and control group (n=63). In the control group we adopted routine health education and routine telephone follow-up after discharge. Apart from that, for the observation group we carried out transitional care by WeChat combined with motivational interviewing. The medication adherence was compared with the Morisky medication adherence scale, and the blood pressure control rate was observed and compared between the two groups. Results? Three months after intervention, the medication adherence of two groups all improved compared with that before intervention;the score of medication adherence of observation group and control group was (4.7±1.7) and (3.8±1.5) respectively with a statistical difference (t=3.192, P＜ 0.05). After intervention, the blood pressure control rate of observation group and control group was 60.3% and 51.5% respectively with a statistical difference (χ2=5.645, P＜ 0.05). Conclusions? Transitional care by WeChat combined with motivational interviewing can improve medication adherence and blood pressure control of young and middle-aged hypertension patients which is worthy of clinical application.
