The pathogenesis of chronic wound healing is complex. It is often difficult to heal due to a long course of disease, difficulty in treatment, and it seriously affects the quality of life in patients. The active ingredients, couplet medicinals, and compound formulas of traditional Chinese medicine (TCM) possess unique advantages in the treatment of chronic wound healing. The phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway is extremely critical in the treatment of chronic wound healing by regulating a series of biological processes, including cell apoptosis, angiogenesis, and inflammatory responses. This article reviews the relevant research on the regulation of the PI3K/Akt signaling pathway by TCM to promote chronic wound healing. It has been found that the active ingredients of TCM (such as geniposide, astragaloside, and ginsenosides, etc.), and compound formulas (such as Chonghe ointment, Huanglian ointment, Shirun shaoshang ointment, etc.) mainly reduce inflammatory responses, promote angiogenesis, regulate cell autophagy, and accelerate wound healing by activating the PI3K/Akt signaling pathway; at the same time, there are also a few couplet medicinals( such as Huangqi-Honghua) and compound formulas (such as Xiangpi Shengji ointment) that exert anti-inflammatory effects by inhibiting this signaling pathway, to promote wound healing.

In recent years, NOD-like receptor protein 3 (NLRP3) inflammasome in tumors has become a research hotspot, especially in melanoma, colorectal cancer, lung cancer, and breast cancer, and more and more evidence has shown that inflammation plays a role in the development, progression, angiogenesis, and invasion of cancer. Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer, and there are still controversies over the role of NLRP3 inflammasome in the development and progression of HCC. Therefore, this article reviews the potential impact of NLRP3 inflammasome in the progression of HCC and its mechanism of action in anticancer therapy, and it is believed that NLRP3 inflammasome can be used as an effective therapeutic target for HCC patients.

Traditional Chinese medicine has a long-standing understanding of the brain;however,the theoretical foundation and treatment approach for diseases related to the brain have not been systematically organized and studied. The three treasures of essence,qi,and spirit are closely associated with the brain in humans. Based on this theory,this study explored the relationship between essence,qi,spirit,and the brain,with the intention that "the brain is the official position of gathering essence,qi,spirit,and in charge of mental activity". It investigated the theoretical implications of the brain,stating that "essence" forms the material basis of the brain's structure,"qi" is fundamental for brain function,and the "conscious spirit" corresponds to the state of the brain,residing in the heart,serving as the external manifestation of the brain,governing aspects like thoughts,consciousness,and emotions. The "primordial spirit" is the axis of the brain,which is rooted in the brain and serves as the internal core of the brain,thereby governing and regulating the central activities of human life. Essence,qi,mental activity,and primordial spirit mutually support and depend on each other,collectively maintaining the function of the brain governing the mental activity. The primordial spirit,which the brain governs,regulating and controlling the essence,qi,and couscious spirit is a specific manifestation of physiological and psychological activities in the human body. This study provides treatment strategies for clinical brainrelated disorders under the theoretical guidance that "the brain is the official position for gathering essence,qi,and spirit,and is in charge of mental activity". These strategies include " nourishing essence and marrow,supplementing qi to ascend clear,and nurturing nourishment and enriching the spirit". This study aims to contribute to the innovation and development of traditional Chinese medicine theories.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective:To evaluate the impact of orthopedic robotic assistance and conventional freehand methods on surgical strategies, the safety of pedicle screw placement, and clinical efficacy in patients with upper cervical spine diseases.Methods:From January 2017 to March 2023, a total of 63 cases with upper cervical spine disease, were divided into two groups based on the screw placement technique: the robot-assisted pedicle screw placement (RA) group (41 cases) and the conventional freehand pedicle screw placement (CF) group (22 cases), were retrospectively included. These patients in the RA and CF groups underwent two types of posterior cervical surgery, including occipitocervical fusion (9 cases and 8 cases) and fixation and fusion of atlantoaxial and distal vertebrae (32 cases and 14 cases). The outcome parameters, including the disease course, surgical time, intraoperative blood loss, fluoroscopy frequency, radiation dose, hospital stay, treatment costs, complications, the rate of the pedicle screw placement, accuracy of upper cervical pedicle screw placement, and the risk factors that possibly affected the accuracy were recorded and analyzed. Postoperative follow-up was conducted for at least 6 months, and the efficacy of patients was assessed using imaging parameters, ASIS classification, VAS, and JOA scores.Results:Both groups had no screw-related complications and no spinal cord or vertebral artery injuries. In the RA group, the pedicle screw placement rates for the patients with occipitocervical fusion, and fixation and fusion of atlantoaxial and distal vertebrae were 100% (48/48) and 89.6% (138/154), respectively, far exceeding the placement rate in the CF group 42.9% (18/42) and 78.3% (54/69) (χ 2=37.403, P<0.001; χ 2=5.128, P=0.024). The fluoroscopic exposure dose and operation time of the two types of surgical patients in the RA group were both higher than those in the CF group ( P<0.05). Compared with the CF group, the accuracy of C 1 screws in the RA group increased from 42% (11/26) to 80% (51/64), with statistical significance (χ 2=13.342, P=0.004); while the accuracy of C 2 screws improved from 77% (33/43) to 88% (63/72) with no statistical difference (χ 2=2.863, P=0.413). Non-parametric correlation analysis found a significant correlation between the accuracy of C 1 and C 2 pedicle screw placement and the order of guide wire insertion in the RA group ( r=0.580, P<0.001; r=0.369, P=0.001). Postoperatively, both groups showed significant differences in cervicomedullary angle (CMA), Chamberlain angle (CL), McGregor angle, Boogard angle, Bull angle, clivus-canal angle (CCA), occipitocervical (C 0-C 2) angle, posterior occipitocervical angle (POCA), C 2-C 7 angle, and anterior atlantodental interval (ADI) ( P<0.05). The ASIA classification improved to varying degrees for both groups postoperatively, but there were no statistically significant differences between preoperative, postoperative, and last follow-up evaluations. VAS and JOA scores significantly improved for both groups postoperatively and at the last follow-up ( P<0.05). Conclusion:Both orthopedic robotic-assisted and conventional freehand pedicle screw placement techniques achieved satisfactory therapeutic effects in the treatment of upper cervical spine diseases. The orthopedic robot can effectively ensure the accuracy of upper cervical pedicle screw placement, the increase placement rate of pedicle screws in the upper cervical spine, and reduce fluoroscopy exposure. However, it is necessary to avoid the vertebral displacement caused by the priority insertion of the guide needle, which may affect the accuracy of subsequent planning.

Objective:To compare the clinical efficacy of robotic-assisted and fluoroscopy-assisted minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF).Methods:A total of 27 patients with lumbar degenerative disease receiving robot-assisted MIS-TLIF (robot-assisted group) treatment in the First Affiliated Hospital of Nanjing Medical University from May 2020 to September 2021 were retrospectively analyzed, including 9 males and 18 females, aged 61.00±9.11 years (range, 41-71 years). Twenty-seven patients who received fluoroscopic-assisted MIS-TLIF (fluoroscopic-assisted group) during the same period were selected as controls, including 16 males and 11 females, aged 56.70±11.97 years (range, 32-76 years). Operation time, intraoperative bleeding, radiation exposure time, postoperative drainage, hospitalization time, visual analogue scale (VAS) for pain, Oswestry disability index (ODI), accuracy of pedicle screw placement, and postoperative complications were recorded. The learning curve of the robot-assisted group was drawn based on the amount of surgery and the operation time by fitting the logarithmic curve.Results:All patients successfully completed the operation and were followed up for 15.44±3.89 months (range, 12-24 months). The operation time, drainage volume, and hospitalization time in the robot-assisted group were 181.44±36.43 min, 43.70±22.04 ml, and 5.04±1.40 d, respectively, which were smaller than 223.22±59.40 min, 74.63±71.86 ml, 6.59±3.04 d in the fluoroscopy-assisted group, and the differences were statistically significant ( P<0.05). The radiation exposure time in robot-assisted group was 77.78±9.81 s, which was larger than fluoroscopy-assisted group (63.78±17.70 s). There were statistically significant differences in lumbar VAS scores between the two groups before and after surgery ( P<0.05), 3 days after operation and the last follow-up was smaller than those before operation. The VAS score on postoperative day 3 in the robot-assisted group was 2.52±0.98, which was less than 3.07±0.87 in the fluoroscopically-assisted group ( t=0.294, P=0.032). In both groups, 108 pedicle screws were placed, and the accuracy of nail placement in the robot-assisted group was 93.5% (101/108), which was greater than that in the fluoroscopically-assisted group 77.8% (84/108), and the difference was statistically significant (χ 2=11.821, P=0.008). By fitting a logarithmic curve to describe the relationship between the number of operations and the operation time of the robotic-assisted group of operators, the results showed that the operation time decreased with the increase of the number of operations, and the operation time fluctuated greatly in the first 10 cases, and then gradually shortened and stabilized after 10 operations. Conclusion:Robot-assisted MIS-TLIF can improve the accuracy of pedicle screw placement, improve the early postoperative pain and shorten the learning curve.

ObjectiveStudy on the mechanism of Guishao Yunpi decoction in preventing and treating breast hyperplasia based on phosphatase and tensin homolog (PTEN)/ phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) pathway. MethodSeventy SPF-grade SD rats were randomly assigned into blank group (n=15) and modeling group (n=55). The mammary gland hyperplasia model of liver stagnation and spleen deficiency was established by the comprehensive modeling method (hunger and satiety abnormality + tail stimulation + estradiol benzoate + progesterone), and then 5 rats were randomly selected for model verification. The modeled rats were then randomly assigned into five groups: model group, positive control (4 mg·kg-1·d-1 tamoxifen) group, and high-, medium-, and low-dose (17.2, 8.6, 4.3 g·kg-1·d-1, respectively) Guishao Yunpi decoction groups, with 10 rats in each group. The rats in the blank group and model group were given 10 mL·kg-1·d-1 distilled water, and those in other groups were orally administrated with corresponding drugs. After 30 days of treatment, the general living conditions of rats were observed, and the thickness of breast tissue was measured by an ultrasonic diagnostic instrument. The open field test was carried out for behavioral evaluation. The levels of B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X (Bax) in the breast tissue were determined by enzyme-linked immunosorbent assay (ELISA). The mRNA and protein levels of PTEN, PI3K, and Akt in the breast tissue were determined by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively. ResultCompared with those in the blank group, the rats in the model group were irritable, curled up in clusters, and showed positive behavior in the open field test. The modeling led to nipple swelling and increased the breast thickness (P<0.05). Moreover, the modeling elevated the level of Bcl-2 and lowered that of Bax in the breast tissue (P<0.05), down-regulated the mRNA and protein levels of PTEN, and up-regulated the mRNA and protein levels of PI3K and Akt (P<0.05). Compared with the model group, drug administration relieved the general survival state, the degree of nipple swelling, and the positive behavior in the open field test and reduced the breast thickness (P<0.05). In addition, drug administration reduced the level of Bcl-2 and increased that of Bax in the breast tissue (P<0.05), up-regulated the mRNA and protein levels of PTEN, and down-regulated the mRNA and protein levels of PI3K and Akt (P<0.05). ConclusionGuishao Yunpi decoction can improve the general living conditions and alleviate the mammary gland hyperplasia of rats with the syndrome of liver depression and spleen deficiency, which may be realized by the regulation of the PTEN/PI3K/Akt pathway.
