Traditional Chinese medicine(TCM) decoction pieces are a core carrier for the inheritance and innovation of TCM, and their quality and safety are critical to public health and the sustainable development of the industry. Conventional quality control models, while having established a well-developed system through long-term practice, still face challenges such as relatively long inspection cycles, insufficient objectivity in characterizing complex traits, and urgent needs for improving the efficiency of integrating multidimensional quality information when confronted with the dual demands of large-scale production and precision quality control. With the rapid development of artificial intelligence, machine learning can deeply analyze multidimensional data of the morphology, spectroscopy, and chemical fingerprints of decoction pieces by constructing high-dimensional feature space analysis models, significantly improving the standardization level and decision-making efficiency of quality evaluation. This article reviews the research progress in the application of machine learning in the processing, production, and rapid quality evaluation of TCM decoction pieces. It further analyzes current challenges in technological implementation and proposes potential solutions, offering theoretical and technical references to advance the digital and intelligent transformation of the industry.

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 investigate the effect and mechanism of Chaihu Jia Longgu Mulitang （CJLM） on hippocampal NOD-like receptor protein 3 （NLRP3）inflammasome pathway in rats with depression. Method:Sixty male SD rats were randomly divided into a normal group，a model group， a MCC950 （1 mg·kg^-1） group， and high- （13 g·kg^-1）， medium- （6.5 g·kg^-1）， and low-dose （3.25 g·kg^-1） Chaihu Jia Longgu Mulitang groups， with 10 rats in each group．The depression model was induced by isolation combined with chronic unpredictable mild stimulation（CUMS） in rats except for those in the normal group. Rats were treated correspondingly for 21 days by intraperitoneal injection in the MCC950 group and gavage in other groups. The normal group and the model group received an equal volume of normal saline. The depression-like behaviors of rats were observed by sucrose preference test （SPT） and novelty-suppressed feeding test. Enzyme-linked immunosorbent assay （ELISA） was used to determine the levels of interleukin-1β （IL-1β） and IL-18 in the hippocampus of depressed rats. Western blot was used to detect the protein levels of NLRP3， apoptosis-associated speck-like protein containing a C-terminal caspase recruitment domain （ASC）， and Caspase-1. Result:Compared with the normal group， the model group showed decreased sucrose preference rate （P<0.01）， prolonged novelty-suppressed feeding time （P<0.01）， enhanced protein expression of NLRP3，ASC， and caspase-1 （P<0.05， P<0.01）， and elevated expression of IL-1β and IL-18 （P<0.01）. Conclusion:CJLM can alleviate depression-like behaviors in CUMS-induced model rats， and the underlying mechanism is related to the inhibition of the NLRP3 inflammasome pathway．

Huaihuasan， first recorded in Puji Benshifang by XU Shu-wei from the Southern Song dynasty， consists of four herbs， namely Sophorae Flos （fried）， Platycladi Cacumen （smashed with pestle and baked）， Schizonepetae Spica， and Aurantii Fructus （cut into pieces after the removal of pulp and then fried yellow with wheat bran）. At present， Huaihuasan and its modified formulas vary in clinical usages and dosages， and the resulting outcomes have been investigated. However， there are few reviews uncovering its historical evolution. On this basis， this review systematically combed and verified the historical evolution， dose conversion between ancient and modern times， efficacy， and indications of Huaihuasan， as well as the origin and processing of the contained herbs. The findings have demonstrated that Huaihuasan is composed of four herbs， with the original plants and medicinal parts basically the same as those recorded in the 2020 edition of Chinese Pharmacopoeia. Sophorae Flos refers to the dried flower and bud of Sophora japonica in family Leguminosae， Platycladi Cacumen the dried branch and leaf of Platycladus orientalis in family Cupressaceae， Schizonepetae Spica the dried flower spike of Schizonepeta tenuifolia in family Labiatae， and Aurantii Fructus the dried immature fruit of Citrus aurantium in family Rutaceae or its cultivated varieties. On account of the efficacy in clearing intestine， stopping bleeding， dispersing wind， and moving Qi， Huaihuasan has been mainly used to treat intestinal diseases such as bloody defecation and perianal abscess. In modern clinical practice， it is mainly applicable to patients with hematochezia and bleeding due to internal hemorrhoid， ulcerative colitis， or anal fissure. It was suggested that the raw medicinal materials should be decocted and processed according to the methods described in the 2020 edition of Chinese Pharmacopoeia. Following the conversion formula of one Qian=4 g， this paper determined the dosages of Sophorae Flos （fried）， Platycladi Cacumen （smashed with pestle and baked）， Schizonepetae Spica， and Aurantii Fructus （cut into pieces after the removal of pulp and then fried yellow with wheat bran） all to be 2 g， with the total dosage being 8 g. Such comprehensive analysis based on ancient books and modern literature has provided a more scientific reference for the clinical application， research， and development of this classical formula.

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.
