Cancer has become a significant global public health issue， severely impacting public health and societal development. Despite advances in tumor treatment methods in recent years and a gradual decline in cancer mortality rates， drug-related adverse reactions and drug resistance remain substantial challenges. Traditional Chinese medicine （TCM） has demonstrated significant clinical efficacy in cancer treatment and small side effects， making it widely applied in the field of oncology. Xuefu Zhuyutang， derived from Yilin Gaicuo， is known for its abilities to invigorate blood circulation， dispel blood stasis， promote Qi flow， and alleviate pain. It was specifically formulated by the esteemed WANG Qingren of the Qing dynasty for the "blood stasis syndrome in the blood mansion" and is commonly used to treat Qi stagnation and blood stasis syndrome. Clinical studies have shown that Xuefu Zhuyutang， when combined with conventional Western medications， produces significant effects in the treatment of malignant tumors such as liver cancer， lung cancer， and cervical cancer. It substantially reduces the incidence of adverse reactions following Western treatments， including radiation esophagitis， radiation encephalopathy， radiation-induced oral mucositis， and edema. Additionally， it alleviates cancer-related pain and fever， blood hypercoagulability， and associated complications such as depression and anxiety， and also mitigates chemotherapy-induced side effects like hand-foot syndrome. Basic research has demonstrated its potential anti-tumor mechanisms， including the inhibition of Wnt/β-catenin signaling pathway activation， suppression of mitogen-activated protein kinase （MAPK） pathway activation， and anti-tumor angiogenesis. Pharmacological studies have revealed that its active components inhibit tumor cell proliferation and migration， induce tumor cell apoptosis， suppress tumor angiogenesis， enhance the cytotoxicity of natural killer cells against tumors， improve the tumor microenvironment， and regulate immune function. This paper reviewed the latest research progress on Xuefu Zhuyutang in the treatment of malignant tumors from four aspects： theoretical exploration， clinical studies， mechanisms of action， and pharmacological basis， aiming to provide insights and methods for the clinical diagnosis and treatment of malignant tumors.

Chemotherapy is an important treatment for tumors， but most patients experience varying degrees of chemotherapy- induced myelosuppression. Four properties theory of traditional Chinese medicine （TCM） has unique advantages in improving chemotherapy-induced myelosuppression. The monomers from TCM with different properties and flavors， such as cold-natured （e.g. Scutellaria baicalensis， Rhus chinensis）， cool-natured （e.g. Ligustrum lucidum， Ophiopogon japonicus）， warm-natured （e.g. Panax ginseng， Epimedium brevicornu， Curcuma longa， Angelica sinensis）， hot-natured （e.g. Cinnamomum cassia， Aconitum carmichaeli）， and neutral-natured （e. g. donkey-hide gelatin， Lycium barbarum， Rhodiola rosea， fungi）， can exert anti- myelosuppressive effects by reducing damage to hematopoietic stem/progenitor cells， improving the bone marrow hematopoietic microenvironment， inhibiting the oxidative stress response， regulating signaling pathways， so as to ultimately repaire inflammatory damage and improve hematopoietic function， thereby playing an anti-myelosuppressive role.

Mechanical pain is one of the most common causes of clinical pain, but there remains a lack of effective treatment for debilitating mechanical and chronic forms of neuropathic pain. Recently, neurotoxin GsMTx4, a selective mechanosensitive (MS) channel inhibitor, has been found to be effective, while the underlying mechanism remains elusive. Here, with multiple rodent pain models, we demonstrated that a GsMTx4-based 17-residue peptide, which we call P10581, was able to reduce mechanical hyperalgesia and neuropathic pain. The analgesic effects of P10581 can be as strong as morphine but is not toxic in animal models. The anti-hyperalgesic effect of the peptide was resistant to naloxone (an μ-opioid receptor antagonist) and showed no side effects of morphine, including tolerance, motor impairment, and conditioned place preference. Pharmacological inhibition of TRPV4 by P10581 in a heterogeneous expression system, combined with the use of Trpv4 knockout mice indicates that TRPV4 channels may act as the potential target for the analgesic effect of P10581. Our study identified a potential drug for curing mechanical pain and exposed its mechanism.

Traditional Chinese medicine holds that chemotherapy drugs belong to “medicinal toxins”， which are fierce in nature， and while killing tumor cells， they also damage human vitality， firstly disturbing spleen and stomach functions. Based on LI Gao's theory that “fire and original qi are restricted to each other， and one wins while the other loses”， it is believed that the balance between fire and original qi is the guarantee to maintain the material and energy metabolism of the body. As the driving force of human life activities， original qi is the “yang qi” that dominates the qi of the whole body. When the function of spleen and stomach is impaired， and the replenishment of acquired source is insufficient， there will be deficiency of yang qi and hyperactivity of yin fire， manifested as various adverse reactions of the body after chemotherapy. Following the treatment principle of tonifying the spleen and stomach and lifting yang qi， it is recommended to use sweet and warm medicinals to remove heat， and take formulas such as Buzhong Yiqi Decoction （补中益气汤） and Danggui Buxue Decoction （当归补血汤） to treat various post-chemotherapy adverse reactions mainly manifested as fire pathogen damaging fluid and consuming qi， yin deficiency and fire exuberance， alleviate related symptoms， which can not only ensure adequate chemotherapy cycle， but also improve the anti-tumor effect， and improve the quality of life of patients.

Objective:To explore the effect and safety of local spraying tranexamic acid after thyroidectomy.Methods:Randomized double-blind placebo-controlled study method was used. Sixty-four patients underwent scheduled thyroidectomy from December 2022 to August 2023 in Baotou Cancer Hospital were selected. The patients were divided into tranexamic acid group and control group by random digits table method with 32 cases each. Before closing the wound during surgery, 16 ml of tranexamic acid injection with concentration of 25 mg/ml was used to wash the wound and 1 ml of tranexamic acid injection (tranexamic acid 100 mg) used to locally spray in tranexamic acid group; 16 ml of the sterile water for injection was used to wash the wound and 1 ml of sterile water for injection was used locally spray in control group, and then the drainage tube was clipped for 20 min. The neck drainage volume on the first to fourth day after surgery and complication were recorded; the C-reactive protein level before and after surgery was detected.Results:Two patients in each group withdrew from the study midway. The drainage volume on the first, second and third day and total drainage volume in tranexamic acid group were significantly lower than those in control group: (29.10 ± 8.04) ml vs. (38.50 ± 8.67) ml, (18.00 ± 7.33) ml vs. (27.20 ± 10.66) ml, (10.70 ± 5.75) ml vs. (14.60 ± 6.83) ml and (69.20 ± 24.48) ml vs. (96.70 ± 31.90) ml, and there was statistical difference ( P<0.01); there was no statistical difference in the drainage volume on the fourth day after surgery between two groups ( P>0.05). There was no statistical difference in C-reactive protein before and after surgery between two groups ( P>0.05). There was 1 case of fever (body temperature 37.5 ℃) in the control group, and there were no complications such as intermuscular thrombosis, venous thrombosis, incision infection and delayed wound healing in both groups. Conclusions:Local application of tranexamic acid after thyroidectomy can reduce postoperative drainage volume and does not increase the risk of thrombosis, infection and delayed healing.

Objective To study the stress distributions of the surrounding bone during the dynamic implantation of micro-implants,a finite element model of self-attacking orthodontic micro-implant dynamic implantation was proposed and established.Methods A three-dimensional(3D)oral model was constructed using CBCT data.The local model around the implant and the 3D finite element model of the micro-implant were established using ABAQUS software.The micro-implant was implanted into the jaw with an axial propulsion force of 40 N at a constant speed of 0.5 r/s.Results The 3D finite element model was successfully established to simulate dynamic self-attacking orthodontic micro-implant implantation in the jaw bone.The results showed that implantation stage and thread position had significant effects on bone stress distribution and the stress states of different bones had obvious differences:the maximum stress on the cortical bone was 167 MPa,and the maximum stress at the stable stage was approximately 50 MPa.The maximum stress on cancellous bone was 30 MPa.Conclusions The implantation stage and thread position have apparent influences on stress distribution.The stress difference between the cortical and cancellous bones was evident.The stress characteristics can judge the bone type,and whether the jaw is in a suitable implantation state can be judged by the bone stress distributions around the implant.

T 3 rectal cancer patients are a heterogeneous group of populations. T 3 stage patients with good prognosis are similar to their T 2 stage counterparts, and T 3 stage patients with poor prognosis are similar to T 4 stage counterparts. Although small sample clinical trials, meta-analyses and retrospective analyses have been conducted, clinical guidelines are not completely consistent with the definition of risk factors and treatment recommendations for this group of populations. At present, the treatment strategy for T 3 rectal cancer is still controversial, especially the application of perioperative radiotherapy. In this article, current application status and research progress in perioperative chemoradiotherapy for T 3 rectal cancer were reviewed.

The incidence of lateral lymph node metastases (LLN) of locally advanced middle-low rectal cancer (II-Ⅲ stage) is high and clinical prognosis is poor. At present, the treatment plan of LLN is controversial between the East and the West. Scholars from the East represented by Japan believe that LLN is a regional disease. Lateral pelvic lymph node dissection (LPLND) is recommended when the tumor is located under the peritoneal reflection and invades into the muscular layer, regardless of the presence or absence of LLN. However, European and American scholars believe that LLN is a systemic disease and recommend neoadjuvant chemoradiotherapy (nCRT) combined with total mesorectal excision (TME). Nevertheless, recent studies have found that neither nCRT nor LPLND can significantly reduce the locoregional recurrence (LR) rate in patients with LLN, while nCRT combined with LPLND yields better prognosis. Some studies have also demonstrated that increasing the radiotherapy dose of metastatic lymph nodes can improve the local control rate. In this article, current treatment status of this population was reviewed, aiming to provide a basis for clinical treatment.

Objective To investigate the effect of tissue expansion in facial congenital giant nevus.Methods From October 2014 to October 2016,7 cases of facial congenital giant nevus patients were treated with expanded skin flaps,including single expansion and secondary expansion.Partial excision and skin tissue expansion were used to drastically remove giant pigmented nevi on body or extremities of infants.There were some points for attention during the surgery:the size and location of the partial excision and expander should be designed reasonably;no tumor-manipulation and non-tension principle should be taken great notice,and expanders should be linked up with one another when several expanders were used at the same time,so as to reduce the possibility of forming the envelop,which was favorable for the second surgery of transfer of a skin flap.Results All cases of giant pigmented nevi excision were on the face,which were completely removed from the patients.The areas of the nevi were from 7 cm × 5 cm to 15 cm × 13 cm.All patients were followed up for 3-12 months (mean 6 months).All flaps survived well.Expander exposure was happened in 2 cases with no bad results.One case of scar received late repair due to surgical scars and all got satisfactory results.Conclusions Tissue expansion is an ideal method in the treatment of facial congenital giant nevus.
