OBJECTIVE To investigate the effects of osthole (OST) on skin wound healing and angiogenesis in rats by regulating the sonic hedgehog (SHH) signaling pathway. METHODS Full-layer skin defect wound model rats were established and then randomly separated into Model group, OST low-dose, medium-dose and high-dose groups (OST-L group, OST-M group, OST-H group, 20, 30, 40 mg/kg OST), high-dose OST+SHH inhibitor cyclopamide group (OST-H+cyclopamide group, 40 mg/kg OST+10 mg/kg cyclopamide), with 12 rats in each group. Another 12 rats were selected as the control group. The wound healing of rats on 1, 7 and 14 days of administration was observed, and the wound healing rate of rats in each group was measured. The pathological changes and collagen deposition in rat wound tissue were observed; the levels of angiopoietin-1 (Ang-1) and basic fibroblast growth factor (bFGF) in wound tissue of rats were detected; the relative expressions of vascular endothelial growth factor A (VEGFA) and vascular endothelial growth factor receptor-2 (VEGFR-2) mRNA were also detected in wound tissue of rats; the protein expressions of VEGFA, VEGFR-2, SHH and glioma-associated oncogene homolog-1 (GLI1) were determined in wound tissue of rats. RESULTS Compared with Model group, the healing rate of skin wound, relative expression of collagen protein, the levels of Ang-1 and bFGF, the mRNA and protein expressions of VEGFA and VEGFR-2, and the protein expressions of SHH and GLI1 were all significantly increased in OST-M and OST-H groups (P<0.05). The wound tissue underwent significant re- epithelialization, with reduced inflammatory cell infiltration and granulation tissue edema, and an increase in the number of new blood vessels. SHH inhibitor cycloparamide weakened the promoting effects of OST on skin wound healing and angiogenesis in rats. CONCLUSIONS OST may promote skin wound healing and angiogenesis in rats by activating the SHH signaling pathway.

Objective:
To investigate the trends in incidence and mortality of lung cancer in Huangpu District, Shanghai Municipality from 2002 to 2019, so as to provide the evidence for formulating lung cancer prevention and control measures.
Methods:
Data of lung cancer incidence and mortality among residents in Huangpu District from 2002 to 2019 were collected through the Shanghai Cancer Registration and Reporting Management System. The crude incidence and mortality of lung cancer was calculated, and standardized by the data from the Chinese Fifth National Population Census in 2000 (Chinese-standardized rate) and the Segi's world standard population in 1960 (world-standardized rate). The trends in incidence and mortality of lung cancer among residents by age and gender were evaluated using annual percent change (APC).
Results:
A total of 12 965 cases of lung cancer were reported in Huangpu District from 2002 to 2019, and the crude incidence rate was 80.66/105, the Chinese-standardized incidence rate was 34.54/105, and the world-standardized incidence rate was 31.30/105, all showing upward trends (APC=4.588%, 2.933% and 3.247%, all P<0.05). A total of 10 102 deaths of lung cancer were reported, and the crude mortality rate was 62.30/105, showing an upward trend (APC=0.959%, P<0.05); the Chinese-standardized mortality was 25.93/105, and the world-standardized mortality was 22.05/105, both showing downward trends (APC=-1.282% and -1.263%, both P<0.05). The crude incidence and mortality rates of lung cancer in males were higher than those in females (101.39/105 vs. 60.52/105, 85.45/105 vs. 39.87/105, both P<0.05). The crude incidence and mortality rates of lung cancer showed upward trends with age (both P<0.05), reaching their peaks in the age groups of 80-<85 years (341.37/105) and 85 years or above (355.97/105), respectively.
Conclusions
The incidence of lung cancer showed an upward trend, while the mortality showed a downward trend in Huangpu District from 2002 to 2019. Elderly men were the high-risk group for lung cancer incidence and mortality.

Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

ObjectiveTo assess the predictive value of the bladder deformation index (BDI) in determining upper urinary tract (UUT) damage among patients with neurogenic bladder (NB). MethodsClinical data of 132 NB patients admitted to Beijing Bo'ai Hospital from January, 2015 to December, 2018 were retrospectively analyzed. Patients were divided into UUT damage group and normal UUT group according to the presence or absence of hydronephrosis. The demographics, biochemical parameters and video-urodynamics (VUDS) findings were collected, and BDI was calculated. Receiver operating characteristic (ROC) curves were utilized to evaluate the predictive capability. ResultsThere were 54 patients in UUT damage group and 33 in normal UUT group. The course of disease, creatinine level and BDI were siginificantly different between two groups (P < 0.05), while the area under the curve were 0.686, 0.836 and 0.928, respectively. ConclusionCourse of disease, creatinine level and BDI are associated with UUT damage in NB patients, and BDI demonstrates the highest sensitivity and specificity, which may play a role in diagnosis of UUT damage.

BackgroundPatients with depressive disorder often exhibit impaired decision-making functions. However, the relationship between decision-making abilities and depressive and anxiety symptoms in these patients remains unclear. ObjectiveTo explore the characteristics of decision-making behavior in patients with depressive disorder, and to analyze its relationship with clinical symptoms. MethodsA total of 48 patients diagnosed with depressive disorder according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) were recruited from the Department of Psychosomatic Medicine of the Affiliated Hospital of Southwest Medical University from October 2020 to May 2023. Concurrently, 52 healthy individuals matched for age and gender were recruited from Luzhou as the control group. Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) were used for assessment, and decision-making behavior was evaluated using Probabilistic Reversal Learning (PRL) task. Indicators assessed included the number of trials to criterion, perseverative errors, win-stay rate and lose-shift rate. Spearman correlation analysis was used to assess the correlation between BDI and BAI scores and PRL task indicators. ResultsThe depression group showed a significantly higher lose-shift rate compared with the control group (t=3.684, P<0.01). There were no statistically significant differences between two groups in trials to criterion, perseverative errors and win-stay rate (t=0.329, 0.132, 0.609, P>0.05). In depression group, BDI and BAI scores were positively correlated with the win-stay rate(r=0.450, 0.398, P<0.01). ConclusionPatients with depressive disorder are more likely to change their decision-making strategies following negative outcomes. Furthermore, the severity of depressive and anxiety symptoms is associated with a greater propensity to maintain existing decisions after receiving positive feedback.

ObjectiveBased on the conjoint analysis of transcriptome and metabolome, the key genes in the phenylpropanoid biosynthesis pathway of Lonicera macranthoides were explored, which provided a basis for further exploring the synthesis and regulation mechanism of phenylpropanoid compounds in "Xianglei" L. macranthoides. MethodsThe stem, leaves, and three flowering flowers of "Xianglei" L. macranthoides were selected as experimental materials to construct transcriptome and metabolome. The transcriptome and metabolomics were conjointly analyzed by the Kyoto Encyclopedia of Genes and Genomes (KEGG) database and weighted correlation network analysis (WGCNA), and the key genes in the phenylpropanoid biosynthesis pathway of L. macranthoides were explored. ResultsIn this study, 77 differential phenylpropanoids and 315 differential genes were found. Through the joint analysis of transcription and metabolism, nine key differential metabolites and four key genes related to them were finally discovered. Among them, cinnamic acid, 5-O-caffeoylshikimic acid,sinapyl alcohol, and chlorogenic acid were higher in flowers, and the content of the iconic effective component, namely chlorogenic acid,decreased sharply during the withering period. Caffeic acid,ferulic acid, 5-hydroxyconiferaldehyde,p-coumaryl alcohol, and syringin were higher in leaves. These four key genes belong to the cinnamic alcohol dehydrogenase (CAD) family, 4-coumaric acid: Coenzyme A (4CL) family, hydroxycinnamyl transferase (HCT) family, and L-phenylalanine ammonlyase (PAL) family genes. ConclusionAmong the four key genes excavated from L. macranthoides, TRINITY_DN42767_c0_g6 is related to the synthesis of p-coumaryl alcohol and sinapyl alcohol. TRINITY_DN43525_c4_g1 uses caffeic acid,ferulic acid,and cinnamic acid as substrates to catalyze the next reaction. TRINITY_DN47958_c3_g4 correlates with the synthesis of 3-p-coumaroyl quinic acid and caffeoyl-CoA, and TRINITY_DN52595_c1_g2 correlates with cinnamic acid synthesis. These findings provide a basis for further exploring the synthesis and regulation mechanism of phenylpropanoids in "Xianglei" L. macranthoides.
