索塔锚固区的受力分析通常采用实体有限元单元进行，然而由于其结构复杂、种类繁多，不易被一般工程设计人员使用。为此，结合某斜拉桥的实际工程案例，分析了内置式钢锚箱锚固体系的传力特点，提出了一种基于平面框架理论的简化计算方法，并利用非线性的分析方法建立了锚固区ANSYS有限元模型以修正公式。结果表明修正前简化公式计算结果与有限元模型计算结果之间的误差在10%左右；考虑到塔壁厚度、索塔计算高度以及锚箱侧板厚度的影响，使用折减混凝土弹性模量的方法来补偿和修正桥塔应力分布，具体的混凝土折减系数使用非线性回归的方法确定。最终将修正公计算式结果与有限元模型计算结果重新进行对比，结果表明，修正后的计算公式与有限元模型计算结果的误差在2%以内，可以较好地分析索塔锚固区的索力分配情况，具有实际工程意义。

Objective To evaluate the therapeutic effect of Zhuang medicine liquid aroma moxibustion combined with celecoxib on Xiangbi (cervical spondylosis) . Methods 90 patients who met the inclusion criteria for cervical spondylosis from the Pain Clinic of Guangxi International Zhuang Medicine Hospital from January to December 2023 were selected as the research subjects. They were divided into 3 groups: the oral celecoxib control group (Group A, n = 30), the Zhuang Medicine liquid moxibustion control group (Group B, n = 30), and the Zhuang Medicine liquid moxibustion combined with celecoxib experimental group (Group C, n = 30) . During the treatment process, the Visual Analog Scale (VAS), Neck Pain Questionnaire (NPQ), Neck Disability Index (NDI), and Erythrocyte Sedimentation Rate (ESR) were used to evaluate the patients before and after treatment to understand the improvement in pain and neck function among the 3 groups of patients, ultimately summarizing the clinical efficacy of the 3 groups of patients. Results The total effective rate of group C was 93.33% (28/30), while the total effective rate of group A was 86.67% (26/30), and the total effective rate of group B was 83.33% (25/30) . Group C's overall effectiveness rate is significantly higher than that of Groups A and B (P < 0.05) . Patients in all three groups showed a significant decrease in retested VAS, NPQ, NDI scales, and Erythrocyte Sedimentation Rate (ESR) indicators after treatment compared to before, with Group C showing a greater decrease than the other 2 groups (P < 0.05) . Conclusion The combination of Zhuang medicine liquid moxibustion and Celecoxib has good efficacy in treating cervical spondylosis. Clinical evidence indicates a significant and lasting improvement in neck pain symptoms and neck mobility, enabling a rapid recovery of patients' daily self-care abilities, with no apparent adverse reactions. It is worth promoting its clinical application. [ABSTRACT FROM AUTHOR]

Objective: To investigate the effect of glucocorticoids on brain injury in rats with Streptococcus pneumoniae (SP) meningitis, as well as the changes of cerebrospinal fluid immunoglobulin levels under this effect. Methods: A total of 40 SD rats were divided into control group, model group, low-dose methylprednisolone sodium succinate group (Low-MSS) and high-dose methylprednisolone sodium succinate group (High-MSS) according to random table method, with 10 rats in each group. Except for the control group, SP meningitis models were established in other groups. Rats in Low-MSS group and High-MSS group were injected with methylprednisolone sodium succinate by tail vein at doses of 5 mg/kg and 10 mg/kg, respectively, once a day for 21 days. Neurobehavioral scores of rats after modeling were performed by Loeffler method; contents of immunoglobulin IgA, IgM and IgG in cerebrospinal fluid of rats were detected by immunoturbidimetry; levels of inflammatory cytokines TNF-α, IL-6 and IFN-γ in supernatant of rats brain homogenate were determined by ELISA; HE staining was used to detect pathological changes of rats brain tissue; Nissl staining was used to detect the number of neuronal cells in rats brain tissue; TUNEL staining was used to detect the number of apoptotic cells in rats brain tissue; immunofluorescence staining was used to detect expressions of GFAP and S-100b, the marker proteins of rat brain tissue injury. Results: Before SP injection, there was no difference in neurobehavioral scores between control group and model group (P> 0.05), at 24 h, 48 h and 72 h after SP injection, neurobehavioral scores in model group were significantly lower than those in control group (P<0.05). Compared with control group, contents of IgA, IgM and IgG in cerebrospinal fluid of rats in model group were increased, and contents of TNF-α, IL-6 and IFN-γ in supernatant of the brain homogenate were also increased, the tissue was obviously damaged, accompanied by a large number of inflammatory cells infiltration, the number of neuronal cells were decreased, the number of apoptotic cells were increased, and the fluorescence density values of S-100b and GFAP were increased (P<0.05); compared with model group, contents of IgA, IgM and IgG in cerebrospinal fluid of rats in Low-MSS group and High-MSS group were decreased, and contents of TNF-α, IL-6 and IFN-γ in brain homogenate supernatant were also decreased (P<0.05), brain tissue damage was alleviated, inflammatory cell infiltration was significantly reduced, neuronal cells were increased, the number of apoptotic cells were decreased, and the fluorescence density values of S-100b and GFAP were also decreased( P<0.05). In addition, the improvement effect of various indexes and brain tissue damage in High-MSS group was better than that in Low-MSS group, and the difference were statistically significant (P<0.05). Conclusion: Glucocorticoid methylprednisolone sodium succinate can effectively improve the brain tissue damage in SP meningitis rats, regulate the levels of immunoglobulin IgA, IgM and IgG, and has a protective effect on SP meningitis rats.

Hyperbaric oxygen therapy characterized by fewer side effects and simple operation has been explored as a potential therapy for depression. This article provides a review of researches relevant to current clinical application and mechanism of hyperbaric oxygen therapy for depression, aiming to provide valuable references for the formulation of new strategies for the treatment of depression. Hyperbaric oxygen therapy has been demonstrated to be useful as an adjunctive therapy for depression, which can effectively alleviate depression by regulating the homeostasis of hypothalamus-pituitary-adrenal axis, inhibiting inflammation and enhancing synaptic plasticity. And hyperbaric oxygen therapy as adjuvant to antidepressants for depression can contribute to increasing the treatment effectiveness to some extent. [ABSTRACT FROM AUTHOR]

Aiming at the accuracy and simplicity of centrifugal fan in simulation process. RNG k-t; turbulence model and SIMPLEC velocitypressure algorithm were used to solve steady internal flow and LES combined with FW-H acoustic equation were used to solve transient farfield noise by software FLUENT. The effects of the thickness of wind wheel on model simplification, mesh generation, performance calculation was studied, which were compared with the actual measured value. The results show that wind wheel without thickness is superior to wind wheel with thickness in processing model and generating unstructured mesh. Flow distribution and volume flow rate of centrifugal fan are constant, the error is only l. 6% compared to actual value. Due to the influence of turbulence surrounded blades, the noise of wind wheel with thickness is 2. 8% higher than that of wind wheel without thickness, however, the noise of wind wheel without thickness is closer to the actual measured noise.
