ObjectiveThis paper aims to explore the in vitro anti-psoriasis activity and potential mechanism of Kangfuxin liquid (KFX liquid), providing experimental evidence for the anti-psoriasis effect of KFX liquid. MethodsFirstly, the uninduced human immortalized keratinocyte cells (HaCaT cells) were divided into seven groups, namely the control group and KFX liquid groups with different doses (5, 10, 20, 40, 80, 160 g·L-1). After being treated with different concentrations of KFX liquid, the effect of KFX liquid on the normal cell proliferation was detected by using the cell counting kit-8 (CCK-8) method. Secondly, the uninduced HaCaT cells were divided into six groups, namely the control group and recombinant human interleukin-7A (rh-IL-7A) groups with different doses (5, 10, 50, 100, 120 g·L-1). After being treated with different concentrations of recombinant human interleukin-17A (rh IL-17A) liquid, the effect of rh IL-17A on cell proliferation was detected. The optimal induction concentration was screened. Then, normal HaCaT cells were divided into a control group and KFX liquid groups with different doses (5, 10, 20, 40, 80, 160 g·L-1). Except for the control group, the other groups established psoriasis cell models with the optimal induction concentration of rh IL-17A. After being treated with different concentrations of KFX liquid, the effects of KFX liquid on the psoriasis-like HaCaT cell proliferation were investigated. Finally, the uninduced HaCaT cells were divided into six groups, namely the control group, rh IL-17A group, methotrexate (MTX) group, and KFX liquid groups with different doses (20, 40, 80 g·L-1). Except for the control group, the other groups used the optimal induction concentration of rh IL-17A to establish psoriasis cell models. After being treated with different drugs, the cell migration levels were detected through scratch assays, and real-time quantitative polymerase chain reaction (Real-time PCR) was used to detect the relative mRNA expression levels of Ki-67 antigen (Ki67), S100 calcium-binding protein A7 (S100A7), S100 calcium-binding protein A8 (S100A8), and S100 calcium-binding protein A9 (S100A9), thereby comprehensively evaluating the in vitro anti-psoriasis activity of KFX liquid. By detecting the relative mRNA expression levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), and chemokine-20 (CXCL-20) inflammatory-related factors in psoriasis-like HaCaT cells and the protein expression levels of Janus kinase 3 (JAK3), phosphorylated Janus kinase 3 (p-JAK3), signal transducer and activator of transcription 3 (STAT3), and phosphorylated signal transducer and activator of transcription 3 (p-STAT3), the mechanism was explored. ResultsCompared with that of control group, when treated with 80 g·L-1 KFX liquid for 72 h (P<0.05) and at different times with 160 g·L-1 KFX liquid, the HaCaT cell proliferation activity was significantly affected (P<0.01), while the other concentrations of KFX liquid had no significant differences in cell morphology and cell proliferation activity at different times, indicating that the KFX liquid is relatively safe for HaCaT cells and has no obvious toxic side effects. Compared with that of control group, when treated with different concentrations of rh IL-17A for 24 h, the HaCaT cell proliferation activity was significantly enhanced, and the cell activity was the strongest when the concentration was 100 μg·L-1 (P<0.05), with a density close to 100% and intact cell morphology, indicating that 100 μg·L-1 is the optimal concentration for inducing HaCaT cell proliferation. The results of the KFX liquid treatment on rh IL-17A-induced psoriasis-like cells show that the KFX liquid not only effectively inhibits the rh IL-17A-induced psoriasis-like HaCaT cell proliferation activity (P<0.01), but also significantly reduces the migration ability of rh IL-17A-induced psoriasis-like HaCaT cells (P<0.01), and the relative mRNA expression levels of Ki67, S100A7, S100A8, and S100A9 (P<0.01). Moreover, the KFX liquid can significantly reduce the relative mRNA expression levels of IL-1β, IL-6, and CXCL-20 in rh IL-17A-induced psoriasis-like cells (P<0.01), and significantly inhibit the phosphorylation levels of JAK3 and STAT3 proteins (P<0.05, P<0.01). ConclusionThe KFX liquid has no obvious toxicity to uninduced HaCaT cells. It can inhibit rh IL-17A-induced psoriasis-like HaCaT cell proliferation, reduce the cell migration ability, and has good in vitro anti-psoriasis activity. Its action mechanism may be related to downregulating the expression levels of inflammation-related cytokines in the JAK3/STAT3 signaling pathway and inhibiting the phosphorylation levels of JAK3 and STAT3 proteins.

Objective To investigate the effect of spontaneous hypertension on the remodeling of cardiac and aortic tissues in rats, with special attention to the changes in the content of collagen fibers, elastic fibers and secreted Frizzled-related protein 2 (sFRP2) in cardiac and aortic tissues. Methods 28-week-old SHR rats (Spontaneously Hypertensive rats) and WKY (Wistar-Kyoto rats) of the same age were selected as experimental animals. Cardiac load was assessed by calculating the cardiac weight index. Collagen fibers and elastic fibers were isolated from the rat thoracic aorta by hot alkali method, and their content was determined by biochemical analysis. In addition, pathological evaluation of tissue sections of the left ventricle and thoracic aorta were performed by H&E staining, Sirius red staining, and lichen red staining. Western blotting was used to determine the expression level of sFRP2 protein in cardiac tissues. Results Compared with WKY rats, the heart weight index of SHR rats increased significantly (P<0.001), and the results of biochemical analysis and staining of pathological sections showed that the content of collagen fibers in the aorta in the SHR group was higher than that in the WKY group, while the content of elastic fibers was lower, but the difference did not have statistical significance. The content of collagen fibers in the heart of the SHR group was significantly higher than that in the WKY group (P<0.01). Western blotting showed that there was no significant difference in the expression level of sFRP2 protein in heart tissues between the two groups. Conclusion The remodeling of cardiac and aortic tissues in a rat model of spontaneous hypertension may involve complex molecular mechanisms, not just changes in the content of collagen fibers and elastic fibers. The detailed mechanism of the progression of spontaneous hypertension and target organs damage still need further investigation.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective:To compare the prognosis of percutaneous versus laparoscopic microwave ablation in patients with hepatocellular carcinoma (HCC) classified as Barcelona Clinic Liver Cancer (BCLC) stage 0 to A, and evaluate the impact of these two ablation modalities on treatment outcome.Methods:Clinical data of 198 patients with HCC of BCLC stages 0 to A undergoing microwave ablation treatment at the Second Hospital of Jiaxing and Shengjing Hospital of China Medical University from January 2011 to December 2018 were retrospectively analyzed, including 149 males and 49 females, aged (57.4±9.6) years. Patients were divided into two groups based on the treatment modality: percutaneous microwave ablation group ( n=133) and laparoscopic microwave ablation group ( n=65). Survival rates were calculated using the Kaplan-Meier method, and the log-rank test was used to compare survival rates. Univariate and multivariate analyses were performed using Cox regression to assess the impacts of percutaneous and laparoscopic microwave ablation on prognosis. Results:The median overall survivals for the percutaneous and laparoscopic microwave ablation groups were 54 months and 77 months, respectively. The 1-, 3-, and 5-year cumulative survival rates postoperatively were 95.6%, 67.3%, 47.4% for the percutaneous group, and 100.0%, 79.9%, 60.4% for the laparoscopic group, respectively, with the latter showing superior cumulative survival rates ( χ2=4.53, P=0.033). The median recurrence-free survival (RFS) was 27 months for the percutaneous group and 52 months for the laparoscopic group. The 1-, 3-, and 5-year RFS postoperatively were 67.4%, 41.1% and 32.8% for the percutaneous group, and 81.5%, 58.1%, and 46.7% for the laparoscopic group, respectively, with the latter showing superior RFS, and the difference was statistically significant ( χ2=7.20, P=0.007). Multivariate analysis indicated that percutaneous microwave ablation was associated with an increased risk of death ( HR=2.475, 95% CI: 1.423-4.305, P=0.001) and recurrence ( HR=1.996, 95% CI: 1.255-3.176, P=0.004). Conclusion:Laparoscopic approach was superior to percutaneous microwave ablation in patients with HCC of BCLC stages 0 to A, and percutaneous microwave ablation could be a risk factor for poor prognosis in these patients.

This study was designed to investigate the effect of hypoxia on preeclampsia(PE)by modulating the Src/Siglec-6/SHP2 signaling pathway in the cytoplasm of trophoblast cells.Mouse model of PE was established in normal control and Siglec-6 knockdown mice by L-NAME administration,with aims of studying the changes in vascular diameter of spiral arteries in vivo and examining the expression levels of Siglec-6,p-Src,p-Shp2 and p-ERK1/2 proteins in mouse uterine vascular tissues.While,the effect of Src/Siglec-6/SHP2 on the invasive proliferation of trophoblast cells was explored by culturing human chorionic trophoblast cells HTR-8/SVneo with hypoxia in vitro.In vivo experimental assays showed that the diameter of spiral arteries was reduced in the Siglec-6 knockdown group of mice,and the expression levels of Siglec-6,p-Src,p-SHP2 and p-ERK1/2 proteins were significantly reduced.In vitro hypoxic HTR-8/SVneo cell model results revealed that Siglec-6 overexpression could promote trophoblast cell invasion and proliferation by regulating p-Src,p-SHP2,p-ERK1/2,MMP2,P53 and P21.While,suppression of Src and SHP2 eliminated Siglec-6 overexpression-mediated Siglec-6,p-Src,p-SHP2 and p-ERK1/2 expression,and inhibited the ability of Siglec-6 overexpression to mediate trophoblast invasion and proliferation.Taken together,Siglec-6 plays an important role in preeclampsia,and can alleviate preeclampsia by promoting trophoblast invasion and proliferation through the Src/SHP2 signalling pathway.
