Objective To analyze the efficacy of two-hole and four-hole laparoscopic surgery in patients with sigmoid carcinoma,and to explore the influencing factors leading to complications.Methods The clinical data of 130 patients with sigmoid carcinoma who underwent laparoscopic surgery in our hospital from October 2020 to December 2022 were analyzed.The patients were divided into groups according to the surgical perforation methods.Sixty-eight patients in two-hole group were treated with two-hole laparoscopic surgery and 62 patients in four-hole group were treated with four-hole laparoscopic surgery.The perioperative indexes,visual analogue scale(VAS)scores and postoperative complications of patients in the two groups were observed and compared,and the influencing factors of complications were analyzed.Results The total incision length,first time to get out of bed,first postoperative exhaust time,postoperative hospital stay and VAS score at each time point after surgery of patients in two-hole group were significantly shorter/lower than those in four-hole group(P<0.05).There was no statistically significant difference in the incidence of complications between the two groups(P>0.05).Univariate analysis showed that there were statistically significant differences in the age,preoperative albumin,operation time,intraoperative blood loss,first time to get out of bed,first postoperative exhaust time,postoperative hospital stay,VAS scores at the 3rd day and 5th days after surgery of patients in the occurrence group and the non-occurrence group(P<0.05).Further Logistic regression analysis showed that operation time and preoperative albumin<35 g/L were the main influencing factors for the occurrence of complications(P<0.05).Conclusion Compared with four-hole laparoscopic surgery,two-hole laparoscopic surgery for patients with sigmoid carcinoma has shorter time of perioperative recovery,less postoperative pain,and no difference was found in postoperative complications between the two methods.Operation time and preoperative albumin level<35 g/L were the main influencing factors for the occurence of complications.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Colorectal cancer (CRC) is a common malignancy burdening people globally, with increasing morbidity and mortality nowadays, due to the alternation in the diet type and lifestyle in modern society. Berberine, a type of benzylisoquinoline alkaloid, is widely present in numerous medicinal plants, particularly including Coptidis Rhizoma. Mounting evidence reveals that berberine possesses an array of pharmacological effects, such as anti-inflammation, anti-bacterium, anti-cancer, anti-diabetes mellitus and so on. In particular, berberine exhibits substantial inhibition on various types of cancers including CRC. Hereby, we sought to systematically review the suppressive effect of berberine on CRC through the diminishment of the proliferation and metastasis, induction of apoptosis, arrest of cell cycle, regulation of inflammatory reaction, the reverse of chemotherapeutic resistance and restoration of gut microbiota in CRC, so as to shed light on the in-depth mechanisms underlying the treatment of CRC with berberine in the clinical setting.

OBJECTIVE To identify the inhibitory effect of ursolic acid on the colorectal cancer HCT116 cells in vitro and in vivo, and to explore the underlying mechanism. METHODS The smoothened (SMO) gene-silenced human colorectal cancer HCT116hSMO- cell line was established by transfection with the lentivirus carrying SMO shRNA. The cytotoxic effect of ursolic acid on HCT116hSMO-cells was determined by MTT assay. The effect of ursolic acid on the migration of HCT116hSMO- cells was studied by wound healing assay. The effect of ursolic acid on apoptosis of HCT116hSMO-cells was explored by Hoechst33342/PI double staining and flow cytometry. The effects of ursolic acid on the expressions of apoptotic marker gene Bcl-2, Bax, caspase-3 and caspase-9 were measured by real-time quantitative RT-PCR (RT-qPCR) and Western blotting (WB) analysis. RT-qPCR and WB were used to examine the relationship between GLI1, c-Myc expression and PI3K/Akt pathway to further investigate the mechanism of GLI1 activation in HCT116hSMO- cells. The effects of ursolic acid on the expressions of GLI1, p-Akt, Akt, c-Myc, SHH and SUFU of nonca?nonical Hedgehog pathway were evaluated by RT-qPCR and WB assays. Xenograft nude mouse model bearing HCT116hSMO- cells was established and intraperitoneally treated with ursolic acid to investigate the effect on tumor growth in vivo. The body weight and tumor size of mice were assessed regularly every 2 d. The effect of ursolic acid on the apoptosis of tumor tissue was determined by TUNEL assay. The expressions of Bcl-2, Bax, GLI1, p-Akt, Akt, c-Myc, SHH, SUFU mRNA and proteins were measured by RT-qPCR and WB. The levels of Bcl-2, Bax, GLI1, p-Akt, c-Myc and SHH proteins in tumor tissues were also evaluated by immunohistochemistry. RESULTS Ursolic acid significantly inhibited the growth and migration of HCT116hSMO-cells in vitro, compared with the control (P<0.05). Meanwhile, ursolic acid also induced apoptosis of HCT116hSMO- cells in vitro (P<0.05). Furthermore, SC79 (Akt activator) enhanced the expressions of p-Akt, GLI1 and c-Myc, which could be abolished by ursolic acid, and the effect was equal to Akt inhibitor LY294002. The expressions of Bcl-2, GLI1, p-Akt, c-Myc, SHH mRNA and proteins were reduced by ursolic acid, while the levels of Bax and SUFU were increased. Ursolic acid could inhibit the growth and induce the apoptosis of colorectal cancer xeno?graft in vivo. Similarly, lower levels of Bcl-2, GLI1, p-Akt, c-Myc and SHH, and higher expression of Bax and SUFU were noted in ursolic acid-treated mice. CONCLUSION Ursolic acid can inhibit the growth and induce apoptosis of HCT116hSMO- cells both in vitro and in vivo. And the mechanism is related to the suppression of PI3K/Akt-mediated noncanonical Hedgehog signaling pathway.

Pulsatilla chinensis is a widely used traditional Chinese herb, which contains 56 types of chemical constit?uents, mainly including triterpenoid saponins, organic acids, coumarins and lignans. The largest portion of the ingredi?ents in Pulsatilla chinensis is the family of triterpenoid saponins, in which anemoside B4 is the major effective compound and indexing component. The main components of Pulsatilla chinensis can metabolize into a vast array of active prod?ucts in vivo, which play vital roles in its biological activity. Mounting evidence reveals that Pulsatilla chinensis exerts a wide range of therapeutic activities, such as anti-cancer, immunoregulation, anti-inflammation and anti-schistosome, with fewer adverse reactions, via various signaling pathways and multiple targets. It was documented that the active ingre?dient of Pulsatilla chinensis can lessen the drug resistance and synergize the effects of other natural products includ?ing paclitaxel, as well as ameliorate the clinical efficacy of chemical drugs, such as adriamycin. However, Pulsatilla chi?nensis was also reported to be possibly the main cause of hemolysis and chronic liver injury. The efforts should be made to deeply investigate the pharmacological actions and underlying mechanisms of Pulsatilla chinensis, with a focus on the anti-cancer efficacy, and develop new drugs based on the components of Pulsatilla chinensis for future utilization in the clinical setting.

Oleanolic acid (OA) is a pentacyclic triterpenoid chemical component that exists in natural plants with a molecular formula of C30H48O3 and a molecular weight at 456.71 g·mol-1. OA is widespread in traditional Chinese herbal medicine (Ligustri Lucidi Fructus, Achyranthis Bidentate Radix, Red Sage) and berries (blueberries, grapes). In recent years, because of the extensive pharmacological effects of OA, its advantages in disease treatment have become increasingly prominent and gradually attracted the attention of pharmaceutical researchers. OA has effective therapeutic effects on a series of chronic diseases such as inflammation, cancer, diabetes, and cardiovascular diseases through mul?tiple signaling pathways and various targets. Especially in cancers, such as colorectal cancer, liver cancer, gastric cancer, lung cancer, breast cancer and other malignancies, OA presents substantial efficacy. However, its poor aqueous solubility, needy bioavailability, and unsatisfactory pharmacological activity excessively restrict its clinical application. More impor?tantly, the improper utilization of OA can cause adverse reactions, toxic effects and even damage to organs in some spe?cific situations. With the discovery of various pharmacological effects, the complex action mechanisms of OA, the contin?uous progress in structural modification of OA, as well as the synthesis of OA derivatives, its application is expand?ing gradually. Among numerous studies, there is a clear indication that OA and its derivatives, if fully developed, may provide an alternative and cheaper treatment for a variety of chronic diseases. However, the specific molecular mecha?nisms of OA and its derivatives as an alternative therapy and supplementary therapy for cancer, diabetes, cardiovascular disease and other chronic diseases remain to be clarified. Therefore, it is necessary to further study the pharmacokinet?ics, pharmacological activity, specific targets and related mechanisms of OA to lay a solid foundation for drug devel?opment and the application of OA in clinical settings.

OBJECTIVE To investigate the inhibition and mechanism of berberine on human colorectal cancer HCT116 cells through canonical Hedgehog signaling pathway. METHODS The effect of berberine on cell morphology was observed by microscopy. MTT colorimetric assay, cell scratch experiment, colony formation assay and Hoechest/PI staining were utilized to detect the activities of berberine on cell viability, cell migration and cell apoptosis. Flow cytome?try was applied to examine the cell apoptosis. The effects of berberine on caspase-3 and caspase-9 were detected by caspase activity detection kit. The expressions of Hedgehog signaling pathway-related proteins SHH, GLI1, PTCH1, SMO, SUFU, apoptosis-related proteins Bax and Bcl-2 as well as cell cycle-related proteins cyclin D1 were detected by Western blotting. Additionally, quantitative real time RT-PCR was employed to assess the mRNA expression levels of Hedgehog signaling pathway-related genes SHH, GLI1, PTCH1, SMO, SUFU, apoptosis-related genes Bax and Bcl-2 as well as cell cycle-related genes cyclin D1. RESULTS Berberine sharply altered the morphology of human colorectal cancer HCT116 cells, demonstrated by that migration ability of HCT116 cells was reduced significantly and the nuclei were densely stained. Berberine could induce apoptosis in a dose-dependent manner. The activities of caspase-3 and caspase-9 were increased prominently. The expression levels of Hedgehog signaling pathway-related protein SUFU and apoptosis-related protein Bax were augmented substantially. The expression levels of Hedgehog signaling pathway-related proteins SHH, GLI1, PTCH1, SMO, apoptosis-related protein Bcl-2 as well as cell cycle-related genes cyclin D1 were markedly lessened. Besides, the mRNA expression levels of Hedgehog signaling pathway-related gene SUFU and apoptosis-related gene Bax were augmented substantially. The mRNA expression levels of Hedgehog signaling path?way-related genes SHH, GLI1, PTCH1, SMO, apoptosis-related gene Bcl-2 as well as cell cycle-related gene cyclin D1 were markedly lessened. CONCLUSION Berberine, which is the main component of coptidis rhizoma, can remarkably restrain the growth and proliferation, promote apoptosis of human colorectal cancer cells HCT116, and the underlying mechanism may be involved in suppressing the activity of the Hedgehog signaling pathway.
