Most of the current research on depression focuses on neuronal regulation,while the astrocytic mechanism of depression is far from explored.Astrocytes are the most numerous and widely distributed glial cells in the central nervous system.With a complex structural morphology,astrocytes play an important role in a variety of neuropsychiatric disorders by interacting with neuronal synapses,vasculature and other glial cells.Recent studies have shown that astrocytes may be involved in depression by regulating monoamine transmitters,glutamate cycle,synaptic plasticity,energy metabo-lism,and neuroinflammation.This review is intended to inspire new ideas for the treatment of depres-sion and the development of novel drugs based on astrocyte regulation.

Objective:To study the clinicopathological features of Sjogren′s syndrome (SS) with liver injury and to improve the understanding of this disease.Methods:Forty-nine patients with SS complicated with liver injury were collected from Beijing Ditan Hospital, Capital Medical University from October 2008 to January 2022. All patients underwent ultrasound-guided liver biopsy, and all specimens were stained with HE. The histopathologic characteristics were observed and the pathologic indexes were graded. Immunohistochemical stains for CK7, CK19, CD38, MUM1 and CD10 were performed by EnVision method; and special histochemical stains for reticulin, Masson′s trichrome, Rhodanine, Prussian blue, periodic acid Schiff (PAS) and D-PAS stains were conducted .Results:The age of patients ranged from 31 to 66 years, including 3 males and 46 females. SS combined with drug-induced liver injury was the most common (22 cases, 44.9%), followed by autoimmune liver disease (13 cases, 26.5%, including primary biliary cholangitis in eight cases, autoimmune hepatitis in 3 cases, and PBC-AIH overlap syndrome in 2 cases), non-alcoholic fatty liver disease (NAFLD, 9 cases, 18.4%) and other lesions (5 cases, 10.2%; including 3 cases of nonspecific liver inflammation, 1 case of liver amyloidosis, and 1 case of porto-sinusoidal vascular disease). Among them, 28 cases (57.1%) were associated with obvious interlobular bile duct injury, mainly in SS combined with PBC group and drug-induced liver injury group. Twenty-three cases (46.9%) were associated with hepatocyte steatosis of varying degrees. In SS with autoimmune liver disease group, ISHAK score, degree of fibrosis bile duct injury, bile duct remodeling, lymphocyte infiltration of portal area, and plasma cell infiltration, MUM1 and CD38 expression; serum ALP and GGT, IgM; elevated globulin; positive AMA, proportion of AMA-M2 positive and IgM positive were all significantly higher than those in other groups(all P<0.05). Serum ALT, direct bilirubin and SSA positive ratio in SS combined with drug liver group were significantly higher than those in other groups(all P<0.05). The serum total cholesterol level in SS combined with PBC group ( P=0.006) and NALFD group ( P=0.011) were significantly higher than those in other groups ( P<0.05). Conclusions:The pathologic manifestations of SS patients with liver injury are varied. The inflammatory lesions of SS patients with autoimmune liver disease are the most serious, and the inflammatory lesions of SS patients with non-alcoholic fatty liver disease and non-specific inflammation are mild. Comprehensive analysis of liver histopathologic changes and laboratory findings is helpful for the diagnosis of SS complicated with different types of liver injury.

After COVID-19 pandemic, there are still many public health challenges in the world. The double burden of communicable and non-communicable diseases is still heavy in many countries. Mental health and injury are crucial public health problems which are often neglected. Environmental health and food and drug safety are closely related to human health, to which further management and intervention are needed. These problems have different impacts on people at different life stages, resulting in health problems throughout the life course. The current status of public health is far from the requirements set by the Sustainable Development Goals of United Nations or the initiative of "Healthy China 2030". It is necessary for governments and related departments of all countries to consider public health in all policy development to tackle the major challenge to public health.

Objective To screen key genes for ferroptosis in atherosclerosis(AS)using bioinformatics methods and analyze the biological functions of key genes to gain an in-depth understanding of the pathogenesis of AS.Methods AS gene expression profile chip dataset GSE100927 was downloaded from the Gene Expression Omnibus(GEO)database.P＜0.05 and|logFC＞1|were used as the conditions to screen the differential genes of AS.These genes were intersected with ferroptosis gene dataset to screen out the genes related to AS ferroptosis.Gene ontology(GO)functional annotation and enrichment analysis of Kyoto Encyclopedia of Genes and Genomes(KEGG)were carried out.The STRING online analysis tool combined with Cytoscape visualization software was subsequently used to mine genes that play a key role in the biological process of AS,and the AS dataset GSE9874 was used as the verification set to verify the expression of key genes.Blood samples from 30 confirmed AS patients in the cardiovascular department of our hospital from January to March 2023 were collected as the experimental group,while blood samples from 20 healthy volunteers were collected as the control group.Sample RNA was extracted,and quantitative real time polymerase chain reaction(qRT-PCR)was used to verify the selected genes.Results A total of 10 differential genes related to ferroptosis were screened by bioinformatics method.GO functional enrichment analysis showed that differential genes were mainly involved in inflammation,apoptosis,oxidative stress and other biological processes,while KEGG pathway enrichment analysis showed that differential genes were mainly involved in ferroptosis,HIF-1 signaling pathway,and leukocyte migration pathway through endothelial cells.Seven key modules of gene construction were screened out through the protein interaction network,which were FTL,SLC40A1,CYBB,NCF2,HMOX1,DPP4 and ALOX5.GSE9874 was used for verification,and 5 key genes including ALOX5,DPP4,FTL,SLC40A1 and NCF2 were finally screened out.The expression detection of key genes in clinical samples by qRT-PCR showed that compared with the control group,the up-regulated genes in blood of AS group were DPP4(t=1.795,P=0.046),FTL(t=2.218,P=0.029)and SLC40A1(t=2.859,P=0.009),and the down-regulated genes were ALOX5(t=8.039,P＜0.001)and NCF2(t=11.867,P＜0.001),and the differences were significant.The experimental results were consistent with the results of bioinformatics analysis.Subgroup analysis showed that DPP4 expression in plaque group was higher than that in intima thickening group,and the difference was significant(t=2.843,P=0.036).Conclusion The key genes of ferroptosis screened by bioinformatics are AS,ALOX5,DPP4,FTL,SLC40A1 and NCF2,which may be potential targets for the diagnosis and treatment of AS,providing new ideas for the clinical diagnosis and treatment of AS.

Objective:To observe the application effect of a self-designed assisted abdominal breathing rehabilitation device in elderly patients undergoing postoperative chemotherapy for lung cancer.Methods:Self-designed an assisted abdominal breathing rehabilitation device. Used the convenience sampling method, 116 elderly patients admitted to the First Affiliated Hospital of Anhui Medical University from April 2021 to April 2022 undergoing postoperative chemotherapy for lung cancer were selected as study subjects, and they were divided into control and observation groups by the random number table method, with 58 cases in each group. The control group received routine abdominal breathing training, and the observation group used auxiliary abdominal breathing rehabilitation device for abdominal breathing training, and compared the training compliance rate, lung function indexes and six minutes-walk test scores of the two groups before and after 2 weeks of training.Results:After 2 weeks of training, the training compliance rate of patients in the observation group was 100.00% (58/58), which was higher than 87.93% (51/58) in the control group, and the difference was statistically significant ( χ 2=7.45, P<0.05). After 2 weeks of training, FEV 1, FVC, FEV 1/FVC were (1.81 ± 0.29) L, (1.98 ± 0.32) L, (91.91 ± 5.98) % respectively in the observation group, and (1.49 ± 0.31) L, (1.73 ± 0.41) L, (87.11 ± 9.44) % respectively in the control group, there were statistically significant differences between the two groups ( t=-4.13, -2.60, -2.36, all P<0.05). After 2 weeks of training, the six minutes-walk test score was (0.86 ± 0.71) points in the observation group and (1.02 ± 0.74) points in the control group, and the difference was statistically significant ( t=2.05, P<0.05). Conclusions:An assisted abdominal breathing rehabilitation device helps to improve the training compliance rate, enhance lung function recovery and improve exercise endurance in elderly patients undergoing chemotherapy after lung cancer surgery.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

Objective:To evaluate the value of whole-brain radiotherapy (WBRT) combined with simultaneous integrated boost (SIB) and WBRT plus sequential stereotactic radiosurgery (SRS) in the treatment of small-cell lung cancer (SCLC) patients with brain metastases (BM).Methods:A retrospective analysis was performed among 135 SCLC patients with BM who were admitted to Tianjin Medical University Cancer Institute and Hospital from 2007 to 2023. They all received cisplatin- or carboplatin-based first-line chemotherapy and WBRT with 94 patients receiving thoracic radiotherapy after chemotherapy. All patients were divided into the WBRT+SIB ( n=66) and WBRT+SRS groups ( n=69) according to the treatment methods. After propensity score matching (PSM), 63 patients were assigned into each group. The primary endpoints were overall survival (OS) and brain metastasis-related local control (BMRLC) rates. Categorical data, such as gender and age, were compared by Chi-square test. OS and BMRLC were calculated by Kaplan-Meier method. The survival curves between two groups were compared by log-rank test. The risk factors of OS and BMRLC were assessed by multivariate Cox regression models. Results:In all the patients, the median follow-up time was 24.9 (range 6.30-109.57) months. The 2-year OS and BMRLC rates were 49.0% and 85.0%, respectively. Cerebral necrosis occurred in 2 patients. Multivariate analysis revealed that shorter time interval of BM after diagnosis (≤10 months) ( P=0.041), control of extracranial progression ( P=0.029), and lower diagnosis-specific graded prognostic assessment (DS-GPA) (≥2) ( P=0.006) significantly improved OS. After PSM, the 2-year OS rate in the WBRT+SIB group was significantly higher than that in the WBRT+SRS group ( P=0.041), while the 2-year BMRLC rate was not significantly improved ( P=0.203). In the DS-GPA<2 subgroup, the OS in the WBRT+SIB group was significantly higher than that in the WBRT+SRS group ( P=0.016), whereas no significant difference was observed in BMRLC between two groups ( P=0.205). In the DS-GPA≥2 subgroup, no significant difference was found in OS between two groups ( P=0.266), while BMRLC in the WBRT+SIB group was significantly lower compared with that in the WBRT+SRS group ( P=0.027). Conclusions:WBRT+SIB is more suitable for SCLC patients with BM than WBRT+SRS. However, WBRT+SRS yields higher local control for DS-GPA≥2 patients.

Objective:To investigate the expression levels and clinical significance of glioma-associated oncogene homolog 1 (GLI1) and sonic hedgehog signaling molecule (Shh) in the malignant transformation of ovarian endometriosis (EM).Methods:The expressions of GLI1 and Shh were detected by real-time reverse transcription (RT)-polymerase chain reaction (PCR) and EnVision method in 50 cases of ovarian EM tissues, 35 cases of atypical endometriosis (aEM) and 50 cases of endometriosis-associated ovarian cancer (EAOC). The expression differences of two molecular markers in the malignant transformation of ovarian EM were compared, and the relationships between two molecular markers and the clinicopathological features and prognosis of EAOC were analyzed.Results:(1) RT-PCR showed that the expression levels of GLI1 mRNA in EM, aEM and EAOC group were 1.77±0.40, 3.54±0.44, and 7.80±0.24, respectively. The expression levels of Shh mRNA were 0.95±0.21, 3.14±0.35, and 5.41±0.31, respectively. GLI1 and Shh mRNA in EAOC group were significantly higher than those in EM and aEM group (all P<0.01), and there were statistically significant differences between EM and aEM group (all P<0.01). The percentages of GLI1 in ovarian EM, aEM and EAOC were 32% (16/50), 57% (20/35), and 66% (33/50), respectively, meanwhile, the positive expression rates of Shh were 20% (10/50), 49% (17/35), and 54% (27/50), respectively (all P<0.01). GLI1 mRNA expression was positively correlated with Shh mRNA expression in EAOC tissues ( r=0.721, P<0.01). The expressions of GLI1 protein were proportionated to Shh protein in EAOC tissues ( r=0.608, P=0.001). (2) The expression of GLI1 was significantly related to the International Federation of Gynecology and Obstetrics (FIGO) stage, cancer antigen 125 (CA 125) levels, lymph node metastasis, and Platinum resistance in EAOC patients (all P<0.05). The expression of Shh were related to FIGO stage and lymph node metastasis in EAOC patients (all P<0.05). Logistic regression analysis showed that GLI1 expression was an independent risk factor for poor prognosis in EAOC patients ( P<0.05). Kaplan-meier survival analysis showed that the overall survival rate of EAOC patients with high GLI1 expression and low GLI1 expression was 12.1% and 35.3%, respectively, with statistical significance ( χ2=10.73, P<0.01). The overall survival rate of EAOC patients with high and low expression of Shh protein was 11.1% and 30.4%, in which there was statistically significant difference ( χ2=3.96, P=0.047). Conclusion:GLI1 and Shh are highly associated with the malignant transformation of ovarian EM, which may play a role in promoting malignant degeneration of ovarian EM, and the high expression of GLI1 and Shh indicates a poor prognosis in EAOC patients.
