Stroke is the leading cause of death and disability among adults in China, and its common complications include digestive system abnormalities, cognitive impairment, depression, stroke-associated pneumonia, and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang (XLCQT) is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically, XLCQT is often used to treat stroke and its complications. However, the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally, since the basic research is weak, the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis, medicinal properties, safety evaluation, and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients, resveratrol, kaempferol, luteolin, chrysoeriol, apigenin, (+)-catechin, and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex, including inflammatory response, brain-gut axis, hypothalamic-pituitary-adrenal (HPA) axis, intestinal flora, neurotrophic factors, autophagy, oxidative stress, and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

ObjectiveTo establish a mouse model of particulate matter 2.5 (PM2.5)-induced dry eye and investigate whether Chufeng Yisuntang can ameliorate the PM2.5-induced ocular surface damage by regulating the reactive oxygen species (ROS)/p38 mitogen-activated protein kinase (p38 MAPK) signaling pathway. MethodsSixty 8-week-old male C57BL/6J mice were used. Ten were randomly selected as the control group. The remaining 50 mice received topical instillation of 1 drop (0.1 mL) of 5 g·L-1 PM2.5 suspension in both eyes, four times daily. Successfully modeled mice were randomized into four groups (n=10): Model, p38 MAPK inhibitor, Chufeng Yisuntang, and combination (Chufeng Yisuntang at 7.3 g·kg-1 + p38 MAPK inhibitor SB203580 at 5 mg·kg-1). Chufeng Yisuntang was administered via gavage, and the inhibitor group via intraperitoneal injection. The control and model groups received equal volumes of distilled water by gavage. All treatments lasted for 4 weeks. General conditions were dynamically observed. Tear secretion, tear film break-up time, and corneal fluorescein staining were assessed. After intervention for 4 weeks, hematoxylin and eosin (HE) staining was used to examine the histopathological changes. Enzyme-linked immunosorbent assay (ELISA) was adopted to measure serum levels of ROS, malondialdehyde (MDA), superoxide dismutase (SOD) 1, and SOD2. Western blot and Real-time PCR were employed to determine the protein and gene levels, respectively, of p38 MAPK, B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), and cysteinyl aspartate-specific proteinase-3 (Caspase-3) in the corneal tissue. ResultsCompared with the control group, the model group exhibited reduced tear secretion volume and tear film breakup time, along with increased corneal fluorescein staining scores (P<0.01). Compared with the model group, the Chufeng Yisuntang group, p38 MAPK inhibitor group, and combination group demonstrated increased tear secretion volume and tear film breakup time, along with decreased corneal fluorescein staining scores (P<0.01). HE staining revealed that compared with the control group, the model group exhibited marked increases in corneal epithelial cell layers and epithelial thickness, along with reduced meibomian gland acini and intensely stained, densely packed nuclei around the acini. Compared with the model group, the Chufeng Yisuntang group, p38 MAPK inhibitor group, and combination group showed intact corneal structure, improved cell morphology, and reduced damage severity. ELISA revealed elevated ROS and MDA levels (P<0.01) and decreased SOD1 and SOD2 levels (P<0.01) in the model group compared with the control group. Compared with the model group, Chufeng Yisuntang, p38 MAPK inhibitor, and the combination lowered ROS and MDA levels (P<0.01), while raising SOD1 and SOD2 levels (P<0.05, P<0.01). Western blot revealed that compared with the control group, the model group exhibited increased protein levels of p38 MAPK, Bax, and Caspase-3 (P<0.01) and reduced protein level of Bcl-2 (P<0.01). Compared with the model group, Chufeng Yisuntang, p38 MAPK inhibitor, and the combination down-regulated the protein levels of p38 MAPK, Bax, and Caspase-3 (P<0.01), while up-regulating the protein level of Bcl-2 (P<0.01). Compared with the Chufeng Yisuntang group, the combination group exhibited decreased protein levels of p38 MAPK, Bax, and Caspase-3 (P<0.01) and increased protein level of Bcl-2 (P<0.01). Real-time PCR revealed that compared with the control group, the model group exhibited upregulated mRNA levels of p38 MAPK, Bax, and Caspase-3 (P<0.01), and downregulated mRNA level of Bcl-2 (P<0.01). Compared with the model group, Chufeng Yisuntang, p38 MAPK inhibitor, and the combination down-regulated the mRNA levels of p38 MAPK, Bax, and Caspase-3 (P<0.01), while up-regulating the mRNA level of Bcl-2 (P<0.05, P<0.01). Compared with the Chufeng Yisuntang group, the combination group exhibited decreased mRNA levels of p38 MAPK, Bax, and Caspase-3 expression (P<0.05, P<0.01) and increased mRNA level of Bcl-2 (P<0.01). ConclusionChufeng Yisuntang may partially protect against PM2.5-induced corneal injury by inhibiting the ROS/p38 MAPK pathway, enhancing antioxidant defense, and reducing epithelial apoptosis.

Objective:To observe the early clinical efficacy of 3D-printed modular supporting prosthesis for reconstruction of lacunar bone defect caused by giant cell tumor of the distal femur.Methods:From May 2018 to July 2023, a total of 9 patients with giant cell tumor of the distal femur were treated with 3D-printed modular supporting prosthesis to reconstruct lacunar bone defects in the Department of Orthopedics, West China Hospital, Sichuan University. There were 4 males and 5 females, aged 30.8±6.1 years (range, 24-44 years), 5 cases on the left side, 4 cases on the right side, 2 cases of Campanacci grade I, 7 cases of Campanacci grade II. The anteroposterior and lateral X-ray films and T-SMART tomosynthesis imaging of the knee joint were taken to observe the bone graft healing and osseointegration after operation. Musculoskeletal Tumor Society (MSTS)-93 was used to evaluate knee function, and visual analogue scale (VAS) was used to evaluate knee pain.Results:All patients were successfully operated and followed up for an average of 30.8±7.5 months (range, 18-42 months). The operation time was 124.2±23.6 min, and the intraoperative blood loss was 105.6±17.4 ml. All autografts showed bony union at the graft-host junction, and the healing time was 3.3±0.4 months (range, 3.0-4.0 months). At 6 months after surgery, T-SMART tomosynthesis imaging showed that the gap between the prosthesis-bone interface was less than 1 mm in all patients. At the last follow-up, the thickness of residual subchondral bone was 5.7±1.3 mm, which was greater than that before operation 2.2±0.8 mm, and the difference was statistically significant ( t=10.823, P<0.001). At the last follow-up, the score of MSTS-93 was 26.7±2.4, which was higher than that before operation 18.8±3.7, and the difference was statistically significant ( t=5.367, P<0.001). At the last follow-up, the range of motion of the knee joint was 122.8°±9.1°, which was higher than that before operation 108.3°±6.1°, and the difference was statistically significant ( t=3.970, P<0.001). All patients were able to walk normally, go up and down stairs and other daily activities, and 7 patients were able to complete squats. At the last follow-up, there was no local tumor recurrence, distant metastasis, death, joint infection, pain (VAS score was 0), delayed wound healing, joint degeneration, prosthesis loosening or articular surface collapse. Conclusion:Reconstruction of lacunar bone defect caused by giant cell tumor of distal femur with 3D-printed modular supporting prosthesis can effectively improve knee joint function and osseointegration, and the short-term clinical results are satisfactory.
