Knee osteoarthritis is a common joint disease within osteoarthritis,characterized by pain,swelling,and limited functionality as the main clinical manifestations.In severe cases,it affects daily life and falls under the category of"impediment syndrome"or"bone impediment"in TCM.The author believes that the theory of"bones,tendons,and muscles"is closely related to this disease.Treatment should focus on simultaneously nourishing the liver,spleen and kidneys,considering tendons,bones and muscles,while also dispelling wind,cold and dampness.The clinical application of Sanbi Decoction has shown good efficacy,and this discussion aimed to provide ideas for the diagnosis and treatment of knee osteoarthritis.

Aim To explore the clinical efficacy of sequential balloon pulmonary angioplasty(BPA)in the treat-ment of patients with chronic thromboembolic pulmonary hypertension(CTEPH),and analyze the safety during the periop-erative period.Methods 30 patients with CTEPH who underwent BPA treatment at Luoyang Central Hospital affiliated to Zhengzhou University from August 2018 to February 2024 were selected,30 patients with CTEPH who chose drug treatment were set as controls,the patients'gender,age,body mass index,comorbidities,plasma N-terminal pro-brain natriuretic peptide(NT-proBNP)levels,application of pulmonary hypertension targeted drugs,6-minute walking dis-tance(6-MWD),WHO cardiac function classification and cardiac ultrasound pulmonary arterial pressure related data were collected.Right heart catheterization was performed to obtain pulmonary hemodynamic parameters in the BPA group.Changes in WHO cardiac function classification,6-MWD,NT-proBNP,pulmonary vascular hemodynamic parameters and cardiac ultrasound pulmonary artery pressure data before BPA,after the final BPA and at 6-month follow-up were com-pared,as well as differences between the two groups.The occurrence and management results of surgical complications such as pulmonary artery injury,contrast nephropathy and reperfusion pulmonary edema were recorded.Results Compared with before BPA,after the last BPA,cardiac output(CO),cardiac index(CI),and mixed venous oxygen satu-ration(SvO2)increased,mean pulmonary artery pressure(mPAP)and pulmonary vascular resistance(PVR)decreased(all P＜0.05),and 6-MWD,NT-proBNP,right ventricular diameter,right atrial up-down diameter,right atrial left-right diameter,left ventricular diastolic end diameter,and tricuspid regurgitation velocity all improved(all P＜0.05).Com-pared with the control group,the surgical group showed an increase in 6-MWD,a decrease in NT-proBNP levels,a de-crease in right ventricular diameter,right atrial up-down diameter and right atrial left-right diameter,an increase in left ventricular end diastolic diameter,a decrease in tricuspid regurgitation velocity and a significant improvement in WHO car-diac function classification(all P＜0.05).Among 30 BPA patients,2 patients experienced hemoptysis during surgery,1 patient developed reperfusion pulmonary edema after surgery,and 1 patient developed contrast nephropathy.After treat-ment,all patients improved and were discharged.Conclusion Sequential BPA has good clinical efficacy and safety in the treatment of CTEPH patients,and is an effective technique for treating CTEPH,which is worth promoting in clinical practice.

Objective:To investigate the impact of deep learning image reconstruction (DLIR), adaptive statistical iterative reconstruction-veo (ASiR-V) and filtered back projection (FBP) on the histogram and wavelet features of portal venous phase abdominal CT in patients with hepatic tumor.Methods:The CT data of 68 patients with hepatic tumor who underwent enhanced CT scans were retrospectively collected. FBP, 30%ASiR-V, DLIR-L, DLIR-M and DLIR-H images were reconstructed. The images of portal venous phase were reconstructed with five algorithms, including FBP, ASIR-V at a level of 30% (ASiR-V 30%), DLIR at low (DLIR-L), medium (DLIR-M), and high (DLIR-H). Histogram and wavelet features were extracted from hepatic lesion, liver, spleen, kidney and erector spinae muscle, and compared using one-way analysis of variance or Kruskal-Wallis test. Two radiologists delineated the three-dimensional lesions independently and one of them repeated the delineation after one month. Intra-class correlation coefficients ( ICC) among five sets of images were calculated to evaluate the consistency of radiomics features of hepatic lesion. P<0.05 was considered to indicate statistical significance. Results:Most histogram and wavelet features extracted from hepatic lesion, liver, spleen, kidney and erector spinae muscle showed significant differences among five groups (all P<0.05). The number of features without significant differences decreased with the intensity of DLIR reconstruction increased. For histogram features, there were no significant differences of energy, mean, median, and total energy among five sets of images ( P>0.05). For wavelet features, there were no significant differences of mean and median among five sets of images ( P>0.05). The consistency of all histogram features was high except for the mean value of wavelet feature. The intra-and inter-observer ICC ranged from 0.756 to 1 and 0.767 to 1, respectively. Conclusion:Both 30%ASiR-V and DLIR at three levels algorithms had influence on the histogram and wavelet features of abdominal organs and hepatic tumors extracted from CT images in portal venous phase, and the effects expanded with the strengthening of levels. Median can be a reliable quantitative parameter for CT texture analysis of hepatic tumor.

Objective:To construct a stable oral squamous cell carinoma(OSCC)cell line overexpressing miR-181a-5p,and to ob-serve the effects of miR-181a-5p on the biological behavior of the cells.Methods:miR-181a-5p lentivirus and the control virus vec-tor were respectively constructed and respectively transfected into OSCC CAL-27 cells.The stablely transfected cells(OE)and con-trol cells(NC)were screened out by purinomycin.The fluorescence of the cells was observed by laser confocal microscopy.The ex-pression of miR-181a-5p and Bcl-2 was detected by qRT-PCR and the expression of target protein Bcl-2 was detected by Western blot.The invasion,migration and proliferation ability of the cells were detected by cell scratch,Transwell assay and clonal formation assay.qRT-PCR was used to detect the expression of the related genes of cell invasion and migration.Results:It was found that the expression level of miR-181a-5p in OE cells was significantly higher than that in NC and untransfected control cells(P＜0.01).The expression of Bcl-2 in OE cells was significantly decreased.The invasion,migration and proliferation of OE cells were decreased.In ad-dition,the expression levels of MMP2,MMP9,Vimentin and Ki67 in OE cells were decreased,while E-cadherin was increased(P＜0.01).Conclusion:Overexpression of miR-181a-5p can significantly inhibit the proliferation,invasion and migration OSCC cells.

Objective To investigate the role of hydrogen therapy in reducing radiation-induced lung injury and the specific mechanism. Methods Forty C57BL/6 mice were randomly divided into four groups: normal control group, model group, hydrogen therapy group I, and hydrogen therapy group II. A mouse model of radiation-induced lung injury was established. The pathological changes in the lung tissue of the mice were examined with HE staining. Immunofluorescence staining was used to detect the expression of surface markers of M1 and M2 macrophages to observe macrophage polarization. The expression of interleukin (IL)-6, tumor necrosis factor-α (TNF-α), and IL-10 in the lung tissue was measured by immunohistochemistry. The expression of nuclear factor-kappa B (NF-κB) p65 and phosphorylated NF-κB (P-NF-κB) p65 was measured by Western blot. Results HE staining showed that compared with the control group, the model group exhibited alveolar septal swelling and thickening, vascular dilatation and congestion, and inflammatory cell infiltration in the lung tissue; the hydrogen groups had significantly reduced pathological damage and inflammatory response than the model group, with more improvements in hydrogen group II than in hydrogen group I. Immunohistochemical results showed that compared with those in the control group, the levels of the inflammatory cytokines IL-6 and TNF-α were significantly increased in the model group; the hydrogen groups showed significantly decreased IL-6 and TNF-α levels and a significantly increased level of the anti-inflammatory factor IL-10 than the model group, which were more marked in hydrogen group II than in hydrogen group I. Immunofluorescence results showed that compared with the control group, the expression of the surface marker of M1 macrophages in the model group was significantly upregulated; the hydrogen groups showed significantly downregulated M1 marker and significantly upregulated M2 marker, and hydrogen group II showed significantly increased M2 marker compared with hydrogen group I. Western blot results showed that compared with that in the control group, the ratio of P-NF-κB p65/NF-κB p65 in the model group was significantly increased; the P-NF-κB p65/NF-κB p65 ratio was significantly reduced in the hydrogen groups than in the model group, and was significantly lower in hydrogen group II than in hydrogen group I. Conclusion Hydrogen inhalation therapy may reduce the inflammatory response of radiation-induced lung injury by inhibiting the NF-κB signaling pathway to promote the polarization of the macrophage M1 subtype to the M2 subtype.
