OBJECTIVES: To compare the anti-inflammatory, antibacterial and analgesic effects of Yinqiao Powder (YQS) formulated granules and decoction. METHODS: We first evaluated the anti-inflammatory effects of the two dosage forms of YQS in a LPS-induced RAW 264.7 cell model using RT-qPCR and Western blotting. We further constructed zebrafish models of inflammation by copper sulfate exposure, caudal fin transection, or LPS and Poly (I:C) microinjection, and evaluated anti-inflammatory effects of YQS granules and decoction by examining neutrophil aggregation and HE staining findings. In a mouse model of acute lung injury (ALI) induced by intratracheal LPS instillation, the effects of YQS gavage at 10, 15, and 20 g/kg on lung pathologies were evaluated by calculating lung wet-dry weight ratio and using HE staining, ELISA and Western blotting. The microbroth dilution method was used to evaluate the antibacterial effect of YQS. Mouse pain models established by hot plate and intraperitoneal injection of glacial acetic acid were used to evaluate the analgesic effects of YQS at 10, 15, and 20 g/kg. RESULTS: Both YQS granules and decoction significantly reduced TNF-α, IL-6, and IL-1β expressions and p-STAT3 (Tyr 705) phosphorylation level in LPS-induced RAW 264.7 cells, and obviously inhibited neutrophil aggregation in the zebrafish models. In ALI mice, YQS granules and decoction effectively ameliorated lung injury, lowered lung wet-dry weight ratio, and reduced p-STAT3 (Tyr 705) expression and TNF-α and IL-6 levels. YQS produced obvious antibacterial effect at the doses of 15.63 and 31.25 mg/mL, and significantly reduced body torsion and increased pain threshold in the mouse pain models. CONCLUSIONS The two dosage forms of TQS have similar anti-inflammatory, antibacterial and analgesic effects with only differences in their inhibitory effect on TNF-α, IL-6 and IL-1β mRNA expressions in LPS-induced RAW 264.7 cells.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Objective:Using graph theory analysis, this study compares the topological and node attributes of the brain network to explore the differences in gray matter structural and functional network topological properties between bipolar depression (BD) patients with and without obsessive-compulsive symptoms (OCS).Methods:A total of 90 BD patients (27 males, 63 females; median age 19.0(22.0, 25.0) years) were recruited from the psychiatric outpatient and inpatient departments of the First Affiliated Hospital of Jinan University between March 2018 and December 2022. Fifty healthy controls (19 males, 31 females; median age: 23.0 (20.0, 27.0) years) were also enrolled. The BD patients were divided into two groups based on the presence of OCS: 53 with OCS (OCS group) and 37 without OCS (NOCS group). Resting-state structural and functional MRI data were collected for all participants to construct gray matter structural and functional networks. Graph therory analysis was applied to calculate network topological metrics such as small-world properties. The structural and functional network topological properties were compared among the BD-OCS, BD-nOCS, and control groups. Partial correlation analysis was conducted to examine the association between network topological metrics with significant group differences and Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) scores. Support vector machines (SVM) were used with these metrics as classification feature values to improve diagnostic accuracy through pairwise group classification.Results:Structural network analysis of gray matter: compared to HC group, both OCS group and NOCS group showed increased shortest path length and standardized characteristic path length (shortest path length: 0.78 and 0.80 vs. 0.69; normalized characteristic path length: 0.48 and 0.49 vs. 0.43), and decreased global efficiency (0.21 and 0.21 vs. 0.24) compared to the HC group (permutation test, all P<0.05). Compared to NOCS and HC groups, the OCS group showed increased nodal centrality and betweenness centrality in the right rolandic operculum and left superior occipital gyrus (permutation test, all P<0.05). Functional network analysis of gray matter: compared to the NOCS group, the OCS group showed increased node efficiency and decreased betweenness centrality in the cerebellum ( t=2.15, -3.04; all P<0.05); compared to HC groups, the OCS group showed decreased betweenness centrality in the cerebellum and left inferior frontal gyrus, along with increased node centrality and nodal efficiency in the right transverse temporal gyrus ( t=-2.99, -3.61, 3.06, 3.10; all P<0.05). In the OCS group, betweenness centrality in the left inferior frontal gyrus positively correlated with Y-BOCS scale obsessive thinking score ( r=0.303, P=0.034). Nodal centrality and node efficiency of the right transverse temporal gyrus negatively correlated with Y-BOCS total score ( r=-0.301, -0.311) and Y-BOCS obsessional thinking scores ( r=-0.385, -0.380) separately(all P<0.05). SVM classification: the combined network features achieved an area under the curve of 0.80 in distinguising OCS from NOCS patients. Conclusion:BD-OCS and BD-nOCS patients both exhibit consistent changes in gray matter structural network topology, with the OCS group displaying more pronounced nodal topological abnormalities. Multi-network feature integration demostrates potential for diagnostic classfication.

Prostate cancer is one of the most common malignant tumors in men and posing a serious threat to men's health. Detection methods such as prostate-specific antigen (PSA), prostate biopsy, and magnetic resonance imaging are widely used for prostate cancer screening, but they have low specificity, high cost, and significant risks. Therefore, there is an urgent need to develop highly specific, low-cost, easily obtained, stable, and reliable biomarkers, and use them as the basis to establish non-invasive screening and diagnostic methods for prostate cancer. This paper reviewed the recent advances in the use of prostate cancer biomarkers and combined detection methods for prostate cancer diagnosis and prognosis assessment and provides an in-depth analysis and comparison of different biomarkers and combined detection methods, as well as points out the directions and challenges for future research. The paper emphasizes the importance of developing efficient, cost-effective and easy-to-implement biomarkers to increase the early diagnosis rate of prostate cancer, improve patient prognosis, and reduce the waste of healthcare resources. This paper provides an important theoretical basis and technical guidance for early diagnosis, precise treatment and prognostic evaluation of prostate cancer, and has important reference value for promoting clinical research and practice of prostate cancer.

Acute lung injury (ALI), as a common clinical emergency, is pulmonary edema and diffuse lung infiltration caused by inflammation. The lack of non-invasive alert strategy, resulting in failure to carry out preventive treatment, means high mortality and poor prognosis. Stimulator of interferon genes (STING) is a key molecular biomarker of innate immunity in response to inflammation, but there is still a lack of STING-targeted strategy. In this study, a novel STING-targeted PET tracer, [¹⁸F]FBTA, was labeled with high radiochemical yield (79.7 ± 4.3%) and molar activity (32.5 ± 2.9 GBq/μmol). We confirmed that [¹⁸F]FBTA has a strong STING binding affinity (K_d = 26.86 ± 6.79 nmol/L) and can be used for PET imaging in ALI mice to alert early lung inflammation and to assess the efficacy of drug therapy. Our STING-targeted strategy also reveals that [¹⁸F]FBTA can trace ALI before reaching the computed tomography (CT) diagnostic criteria, and demonstrates its better specificity and distribution than [¹⁸F]fluorodeoxyglucose ([¹⁸F]FDG).

Objective To evaluate the clinical application value of serum high sensitive α-fetoprotein variant ratio (hs-AFP-L3％) in the diagnosis and treatment of hepatocellular carcinoma.Methods From October 2016 to March 2018,at Affiliated Hospital of Qingdao University,160 patients diagnosed with hepatocellular carcinoma,32 patients with intrahepatic cholangiocarcinoma (ICC),52 patients with post-hepatitis B liver cirrhosis,53 patients with chronic hepatitis B and 50 healthy controls were enrolled.The serum levels of hs-AFP-L3％ and α-fetoprotein were measured.Mann-Whitney U test,Spearman correlation analysis,Wilcoxon signed rank test and chi-square test were performed for statistical analysis.Results The serum levels of hs-AFP-L3％ and α-fetoprotein in hepatocellular carcinoma group were 24.90％ (4.68％ to 61.85％) and 113.45 μg/L (11.18 μg/L to 1 803.48 μg/L),respectively,which were higher than those in ICC group (0.50％,0.50％ to 0.50％;and 2.79 μg/L,1.72 μg/L to 4.04 μg/L),cirrhosis group (0.50％,0.50％ to 5.25％;and 18.35 μg/L,3.95 μg/L to 31.93 μg/L),chronic hepatitis group (0.50％,0.50％ to 4.25％;and 2.70 μg/L,1.80 μg/L to 17.00 μg/L),and healthy control group (0.50％,0.50％ to 0.50％;and 1.94 μg/L,1.46 μg/L to 2.63 μg/L),and the differences were statistically significant (U =461.00,1 485.50,1 141.00,625.00;401.50,2 207.00,1 254.00,266.00;all P ＜0.01).The sensitivity of hs-AFP-L3％ and α-fetoprotein in the diagnosis of hepatocellular carcinoma was 66.3％ and 70.0％,respectively;and the difference was not statistically significant (x2 =0.54,P ＞ 0.05).The sensitivity of the combined detection was 82.5％,which was higher than that of the separate detection,and the differences were statistically significant (x2 =24.04 and 18.05,both P ＜0.01).The specificity of hs-AFP-L3％ was 95.2％,which was higher than that of α-fetoprotein (68.6％),and the difference was statistically significant (x2 =26.04,P ＜ 0.01).The specificity of the combined detection of these two markers was 68.6％,which was lower than that of hs-AFP-L3％ alone (95.2％),and the difference was statistically significant (x2 =26.04,P ＜ 0.01).There was no statistically significant difference in the specificity between the combined detection and α-fetoprotein detection alone (68.6％,P ＞ 0.05).The sensitivity of hs-AFP-L3％ in the diagnosis of patients with α-fetoprotein-negative (α-fetoprotein ＜ 20 μg/L) hepatocellular carcinoma was 41.7％.The serum levels of hs-AFP-L3％ and α-fetoprotein were both positively correlated with tumor size and clinical stage (hs-AFP-L3％ r =0.272 and 0.436;α-fetoprotein r =0.375 and 0.458;all P ＜ 0.01).The reduction of serum hs-AFP-L3％ in 38 patients with hepatocellular carcinoma after operation was 82.2％,which was higher than that of oα-fetoprotein (69.2％),and the difference was statistically significant (U =532.50,P =0.049).There was no correlation between serum level of hs-AFP-L3％ and α-fetoprotein level (r =0.077,P ＞ 0.05).Conclusions The sensitivity of hs-AFP-L3％ is similar to that of α-fetoprotein in the diagnosis of hepatocellular carcinoma,while the specificity of hs-AFP-L3％ is higher than that of α-fetoprotein.The combined detection of the two markers can improve the diagnostic rate of hepatocellular carcinoma.The hs-AFP-L3％ has a high diagnostic value in α-fetoprotein-negative hepatocellular carcinoma.

PURPOSE: This study was aimed to investigate the effect of pseudolaric acid B (PAB) on proliferation, invasion and epithelial-to-mesenchymal transition (EMT) in pancreatic cancer cells and to explore the possible mechanism. MATERIALS AND METHODS: The pancreatic cancer cell line SW1990 was cultured and treated with PAB dose- and time-dependent manners. Cell proliferation and invasion ability were measured by MTT assay and Matrigel/Transwell test, respectively. Semi-quantitative real-time polymerase chain reaction and Western blotting were conducted to detect the expression of EMT markers and the key molecules. Finally, nude mice subcutaneous transplantation tumor model was used to confirm the therapy efficacy of PAB. RESULTS: PAB could inhibit SW1990 cell proliferation and invasion in time- and dose-dependent manners. Vimentin, fibronectin, N-cadherin, Snail, Slug, YAP, TEAD1, and Survivin were down-regulated (p < 0.01), while E-cadherin, caspase-9, MST1, and pYAP were up-regulated (p < 0.05). Combined PAB and gemcitabine treatment markedly restricted the tumor growth compared with gencitabin or PAB alone groups. CONCLUSION: PAB could inhibit the proliferation and invasion ability of pancreatic cancer cells through activating Hippo-YAP pathway and inhibiting the process of EMT.

OBJECTIVE:To observe clinical efficacy and safety of mesalazine combined with Kangfuxin solution retention en-ema in the treatment of active ulcerative colitis(UC). METHODS:A total of 120 patients diagnosed as active UC selected from gastroenterology department of our hospital during Mar. 2012 to Aug. 2014 were divided into observation group and control group according to random number table,with 60 cases in each group. Both groups received conventional treatment of active UC. Control group was additionally given Mesalazine enteric coated tablets 1 g,tid,on the basis of routine treatment.Observation group was ad-ditionally given Kangfuxin solution 30 mL diluted with normal saline 150 mL for enema,qd,on the basis of control group. Both groups were treated for 30 d. The serum levels of TNF-α,IL-1,IL-8,IL-10,SOD,NO and LPO were observed in 2 groups be-fore and after treatment;clinical efficacies,recurrence rates,colonoscopy efficacies and the occurrence of ADR were compared be-tween 2 groups. RESULTS:Before treatment,there was no statistical significance in the serum levels of TNF-α,IL-1,IL-8, IL-10,SOD,NO or LPO between 2 groups(P>0.05).After treatment,the serum levels of TNF-α,IL-1,IL-8,NO and LPO in 2 groups were decreased significantly,while the serum levels of IL-10 and SOD were increased significantly;the serum levels of TNF-α,IL-1,IL-8,NO and LPO in observation group were significantly lower than control group,while the serum levels of IL-10 and SOD were significantly higher than control group,with statistical significance(P<0.05). Clinical response rate,recur-rence rate and colonoscopy response rate of observation group were 83.3%,11.7% and 88.3%,which were significantly better than 66.7%,30.0%,70.0%of control group,with statistical significance(P<0.05).There was no statistical significance in the in-cidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Mesalazine combined with Kangfuxin solution can effectively alle-viate inflammatory reaction in patients with active UC,and reduce oxygen free radical damage with good safety.
