Effective treatment of colorectal cancer liver metastases is crucial for improving the survival rate and quality of life of patients with colorectal cancer. With the application of systemic chemotherapy, there have been increases in the conversion rate and surgical resection rate of patients with colorectal cancer liver metastases. Non-radical resection is one of the surgical strategies in tumor surgery. This article reviews the treatment of patients with initially unresectable colorectal cancer liver metastases, including extrahepatic metastasis, R1 resection of liver metastases, staged surgery for liver metastases, and debulking surgery, as well as the application of non-radical resection in the treatment of colorectal cancer liver metastases.

The liver is a common metastatic site of malignant tumors, and liver metastasis is also the leading cause of death due to metastatic tumors. Metastatic liver cancer has high heterogeneity, and there has been slow progress in the treatment of metastatic liver cancer for a long time. In recent years, the development of surgical techniques, systemic therapy, and the multidisciplinary team (MDT) diagnostic and therapeutic mode has led to revolutionary changes in the clinical management of metastatic liver cancer. The article reviews the recent progress in the treatment of metastatic liver cancer from the three aspects of surgical treatment, systemic therapy, and locoregional therapy. Combined therapy based on chemotherapy, targeted therapy, and immunotherapy remains the basic multimodality therapy for metastatic liver cancer. In addition, the development of locoregional therapy has brought new treatment options for patients with metastatic liver cancer. Standardized diagnosis and treatment based on high-level evidence-based evidence and related guidelines and individualized precise treatment under the guidance of MDT will be the future directions for the clinical management of metastatic liver cancer.

During the process of infecting plants,phytopathogenic fungi secrete cell wall degrading enzymes to destroy plant cell walls in order to successfully invade the host. Studies have shown that cellulase,pectinase,xylanase,chitinase,and esterase in the cell wall degrading enzymes secreted by pathogenic bacteria are involved in the process of plant cell wall degradation and pathogenic bacteria. However,there is relatively little research on the function of the lytic polysaccharide monooxygenase in the cell wall degrading enzymes in the process of pathogen invasion of plants. Based on the recent research progress of auxiliary active enzymes and cleavage polysaccharide monooxygenases belonging to the auxiliary active enzymes,this article summarizes the distribution,types,functions of auxiliary active enzymes and the role of cleavage polysaccharide monooxygenases in plant diseases. The research aims to provide reference and basis for the function research and disease prevention and control of auxiliary active enzymes in plant diseases. [ABSTRACT FROM AUTHOR]

Objective: To explore the clinical characteristics, delayed diagnosis factors and complication risk factors of children with tracheobronchial foreign body. Methods: A total of 167 children with suspected tracheobronchial foreign bodies, admitted to our hospital from May 2014 to July 2022, were used as the study subjects. Among the 167 patients, 112 were male and 55 were female, with a mean age (25.10 ± 21.51) months. According to the results of bronchoscopy, the children were divided into foreign bodies (n=140) and non-foreign bodies (n=27). The child was divided into delayed diagnosis group (n=100) and early diagnosis group (n=40) according to whether the diagnosis time of the child was admitted within 24h. All children were divided into complications (n=122) and complications (n=18). Results: There were no significant differences between the foreign body group and the non-foreign body group in terms of gender, age, and time to see a doctor after onset (P>0.05). There were significant differences in the retention site, CRP, PCT, imaging at the first diagnosis, residence of the children and the history of foreign body inhalation(P>0.05). The multivariate logistics regression, with whether delayed diagnosis was the dependent variable, showed that age, imaging at first diagnosis, residence of the child, and history of foreign body inhalation were independent risk factors (P>0.05). The results of multifactorial logistic regression with the occurrence of complications as the dependent variable showed that age, imaging at the first visit, the child's place of residence, delayed diagnosis and history of foreign body aspiration were independent risk factors (P>0.05). Conclusion: Children with tracheobronchial foreign bodies have obvious age characteristics, delayed diagnosis and complications are affected by complex factors such as age, foreign body inhalation history and imaging examination.

Objective To study the efficacy of fibrinogen (FIB) concentrate combined with carboprost tromethamine in the early treatment of postpartum hemorrhage (PPH). Methods Patients with PHH admit-ted to the hospital from January 2018 to May 2021 were selected as study subjects and divided into the experi-mental group (32 cases) and the control group (32 cases) by randomized number tables. The experimental group was treated with (0. 2-0. 3g) / 10 kg FIB concentrate combined with 250 jig carboprost tromethamine, and the control group was treated with 250 pg carboprost tromethamine. The clinical efficacy and blood loss, coagulation indexes [activated partial thrombin time (APTT), plasma thrombin time (TT),prothrombin time (PT),FIB,and D-dimer (D-D)] before and after medication of the two groups were compared. Results The total effective rate of experimental group was 90. 62% (29/32),which was significantly higher than that of the control group 68.75% (22/32),and the difference was statistically significant (P<0. 05). There was no statistical significance in the blood loss between the two groups at 15 min postpartum (P>0. 05), and the blood loss in the experimental group was significantly less than that in the control group at two hours after drug treatment and 24 hours after postpartum, with statistical significance (P<0.05). There was no statistical significance in APTT,TT,PT,FIB and D-D values between the two groups before delivery ( P >0. 05). APTT, TT,PT and D-D values of the experimental group were significantly lower than those of the control group after delivery, while FIB value was significantly less than that in the control group at two hours after drug treatment and 24 hours after postpartum, with statistical significance (P<0.05). There was no statistical significance in APTT, TT,PT, FIB and D-D values between the two groups before delivery (P>0.05). APTT, TT,PT and D-D values of the experimental group were significantly lower than those of the control group after delivery, while FIB value was significantly higher than that of the control group, with statistical significance (P<0.05). Conclusion The combination of FIB concentrate and carboprost tromethamine in the treatment of PPH has better effect, less blood loss and better coagulation function, which is worthy of further clinical research and promotion.

Objective To investigate the effect of Liu-Shen-Wan on transplanted tumors in mice with colon cancer based on the polarization of M2 macrophages in the tumor microenvironment. Methods We established a subcutaneous transplantation tumor model of mice with CT26 colon cancer. Mice were randomly divided into vehicle, oxaliplatin, and oxaliplatin combined with Liu-Shen-Wan groups. Treatment was administered for three weeks, and tumor volume was measured. All mice were weighed during the administration. After the end of the treatment, the mice were dissected and tumors were photographed and weighed. Spleen index was calculated. The expression levels of IFN-γ and IL-12P40 in serum and related blood biochemical indices were measured. The expression levels of M2 macrophage polarization indices, namely, IL-10 and TGF-β, in serum and tumor tissues were detected. The infiltration degree of M2 macrophages in each group was observed by immunohistochemical experiments. Results The tumor volume and mouse weight in the oxaliplatin combined with Liu-Shen-Wan group significantly decreased compared with those in the vehicle group. The spleen index increased, and the expression levels of IFN-γ and IL12P40 in serum also significantly increased. The mice had no obvious side effects after the drug treatment. In addition, the expression levels of IL-10 and TGF-β in the serum and tissues of mice in the oxaliplatin combined with Liu-Shen-Wan group significantly decreased. The expression levels of CD68 and CD206 in tumor tissues also decreased. Conclusion The anti-tumor effect of Liu-Shen-Wan on the transplanted tumors of mice with colon cancer is related to the inhibition of M2 macrophage polarization in the tumor microenvironment.

With lithium acetate and butyl titanate as lithium and titanium sources, and cetyltrimethylammonium bromide (CTAB) as the soft template, the sol-gel method is used to obtain CTAB-added lithium titanium by roasting. The compound (Li4Ti5O12) was pickled with hydrochloric acid to prepare a lithium titanium ion sieve (H4Ti5O12, HTO). The effects of crystal phase, morphology and time on the adsorption capacity of lithium titanium ion sieve were investigated by thermogravimetric analysis (TG-DTG), X-ray diffraction (XRD), scanning electron microscopy (SEM), contact angle and performance tests. Compared with the addition amount of CTAB, 0.1 g CTAB ionic sieve precursor has fewer impurities and pure crystal phase. The quasi-second-order kinetic correlation coefficient R²(0.997 24) of HTO is greater than that of first-order kinetic correlation coefficient R²(0.984 35), indicating that the adsorption process is consistent with chemisorption. The adsorption capacity of HTO in Li+ solution for 24 h reaches 24.44 mg/g, and after 8 times of adsorption and desorption, the adsorption capacity remains at 23.68 mg/g, only reduces by 3.1%. Therefore, HTO has good cyclic adsorption performance and stability, and has a broad market prospect. [ABSTRACT FROM AUTHOR]
