Colorectal cancer （CRC） is one of the most common cancers， with its incidence ranking high among cancers. It stands as the second leading cause of cancer-related death worldwide. In the early stages， CRC lacks specific symptoms， and most patients are diagnosed at advanced stages， making it a major research focus in the field of gastrointestinal tumors. Currently， clinical CRC treatments face several common challenges， including high surgical risks， frequent metastasis and recurrence， drug resistance， and significant side effects from chemotherapy and radiation therapy. With the development and application of traditional Chinese medicine （TCM）， it has been found that TCM and its active ingredients can effectively inhibit CRC cell proliferation， invasion， migration， and angiogenesis， and promote apoptosis and autophagy， thereby slowing the progression of CRC. This has become a key focus of CRC treatment research. Salvia Miltiorrhiza has multiple pharmacological effects， including activating blood circulation to dispel blood stasis， unlocking meridians to relieve pain， clearing heat to calm irritability， and cooling blood to reduce abscesses. It contains a variety of chemical components， including diterpenoids， phenolic acids， flavonoids， polysaccharides， nitrogen-containing compounds， steroids， and lactone compounds. This review summarized the molecular mechanisms of Salvia miltiorrhiza and its active ingredients in the treatment of CRC. It is found that these ingredients exert anti-CRC effects through various molecular mechanisms， including cell cycle arrest， promotion of apoptosis， inhibition of cell invasion and migration， induction of autophagy， suppression of tumor angiogenesis， and remodeling of the tumor microenvironment. The review aims to provide new insights for the drug development and clinical application of Salvia miltiorrhiza in CRC treatment.

Objective: To investigate the correlation between color parameters (L^*, a^*, b^*, Eab^*) and the contents of reducing sugars, total polysaccharides, total oligosaccharides, as well as four saccharides (fructose, glucose, sucrose, and kestose) during the nine cycles of steaming and sun-drying processing of Polygonatum kingianum, and to preliminarily explore the optimal processing duration.
Methods: The color changes were objectively evaluated using a colorimeter. The anthrone-sulfuric acid method was employed to determine total polysaccharides and oligosaccharides. The 3,5-dinitrosalicylic acid (DNS) colorimetric method was used to measure total reducing sugar content. High-performance liquid chromatography coupled with charged aerosol detection (HPLC-CAD) was applied for quantitative analysis of fructose, glucose, sucrose, and kestose. Multivariate statistical analysis was conducted to assess samples from different processing stages.
Results: Significant variations in color and component contents were observed across processing stages. The herbal pieces progressively darkened with increased processing cycles: brightness (L^*) and total color difference (Eab^*) initially decreased then stabilized, while a^* (red-green) and b^* (yellow-blue) values first increased then declined. Total polysaccharides and oligosaccharides showed overall decreasing trends, whereas reducing sugars initially increased before stabilizing. Fructose and glucose levels rose continuously, while sucrose and kestose decreased progressively, becoming undetectable after five cycles.
Conclusion: The chromatic alteration and saccharide composition of P. kingianum showed significant correlation with processing duration. Both total color difference (Eab^*) and reducing sugar content stabilized after four processing cycles (12 hours), suggesting that four cycles of steaming and sun-drying may represent the optimal processing duration.

Objective: To investigate the correlation between the color parameters (L^*, a^*, b^*, Eab^* values) of Polygoni Multiflori Radix Praeparata powder prepared by different processing techniques and the contents of 2,3,5,4’-tetrahydroxystilbene-2-O-β-D-glucopyranoside, emodin, physcion, emodin-8-O-β-D-glucopyranoside, physcion-8-O-β-D-glucopyranoside.
Methods: The L^*, a^*, b^* and Eab^* values of Polygoni Multiflori Radix Praeparata powder prepared by different processing techniques were determined by spectrophotometer, and the contents of the five components were determined by high performance liquid chromatography. Secondly, SPSS 26.0 software and Simca 14.1 software were used to analyze the correlation.
Results: Through the hierarchical cluster analysis (HCA), it was found that the steamed samples and black bean steamed samples could be obviously divided into two categories: raw products and processed products. The processed products could be further divided into 2-8 h and 12-48 h. Pearson correlation analysis showed that the content of stilbene glycoside was significantly positively correlated with L^*, a^* and b^* values (P<0.01). The a^* value was significantly positively correlated with the content of emodin and physcion (P<0.01). Emodin-8-O-β-D-glucoside was positively correlated with L^* value and b^* value, while physcion-8-O-β-D-glucoside was negatively correlated with a^* value. Partial least squares discriminant analysis (PLS) showed that 2,3,5,4’-tetrahydroxystilbene-2-O-β-D-glucoside (VIP=1.69) and emodin-8-O-β-D-glucoside (VIP=1.06) were the key variables affecting chromaticity characteristics (P<0.01).
Conclusion: The three processes of steaming, black bean steaming and black bean stewing are consistent in composition transformation and chromaticity variation, and stilbene glycoside can be used as a specific index component to characterize the processed color. Chromatic parameters can effectively reflect the processing progression and serve as quality monitoring indicators during production.

Objective To study the effect of auditory and speech development after cochlear implant(CI)in children with bilateral cochlear nerve deficiency(CND)and its influencing factors.Methods A total of 20 children with bilateral CND were included in the study,of which 5 were implanted bilaterally and 15 unilaterally.CT of the temporal bone showed stenosis of the cochlear aperture in 14 cases and atresia of the cochlear aperture in 6 cases.There were 8 cases accompanied by other inner ear malformations,and 12 cases with no accompanying inner ear mal-formations.MRI of the internal auditory canal showed 1 nerve in 5 cases,2 nerves in 6 cases,3 nerves in 8 cases,and 4 nerves in 1 case.There were 6 cases in which the EABR was not elicited and 14 cases in which it was elicited.The postoperative auditory and speech abilities of the subjects were evaluated using categories of auditory perform-ance(CAP)and speech intelligibility rating(SIR).Results ① The CAP(P＜0.001)and SIR(P＜0.001)scores of the children with stenosis of the cochlea nerve canal were higher than those of the patients with atresia of the cochlea nerve canal.② The more nerve roots in the internal auditory canal,the higher the score of CAP(P=0.003)and SIR(P=0.008).③ CAP score of the children with EABR elicited was higher than that of the children without EABR elicited(P=0.030).The difference in SIR scores was not statistically significant(P=0.14).④The differences in CAP and SIR between those with bilateral CI and unilateral CI,as well as between those with and without other inner ear malformations,were not statistically significant(P＞0.05).Conclusion Children with bi-lateral CND had significant postoperative improvement in auditory function but poor speech development after CI.Postoperative auditory speech ability was related to the condition of the cochlear foramen,the number of nerve roots in the internal auditory canal,and whether or not the EABR was elicited intraoperatively.

Primers and probes were designed based on the conserved regions of Senecavirus A(SVA),foot-and-mouth disease virus(FMDV),and porcine teschovirus(PTV)and used to devel-op a TaqMan fluorescent quantitative PCR method for detecting the above-mentioned three viru-ses.The triplex fluorescent quantitative PCR system was developed using recombinant positive plasmids containing conserved sequences of the three viruses as templates.After optimizing the conditions,the specificity,sensitivity,repeatability,standard curve,and mixed infection model were evaluated,and the constructed triplex fluorescent quantitative PCR was used for clinical detection.The results showed that this method could specifically detect SVA,FMDV and PTV without cross-reactivity with other pathogens with the minimal detection concentrations for SVA,FMDV,and PTV as low as 1X101 copies/μL,respectively.The coefficients of variation within and between groups were less than 5％.Furthermore,none of the three viruses were detected in 126 samples.The above results indicate that this method is highly specific,sensitive,and stable,making it suit-able for clinical detection.

Objective:To explore the clinical significance of skeletonized lymph node dissection of No.12 lymph nodes after neoadjuvant therapy in patients with advanced gastric cancer.Methods:For this retrospective case-cohort study we collected data from patients with advanced gastric cancer who underwent neoadjuvant chemotherapy and D2 or more extensive curative resection including No.12 lymph node dissection at the First Affiliated Hospital of Sun Yat-sen University from January, 2011 to December, 2022. Patients were divided into two groups based on whether they received skeletonized dissection of No.12 lymph nodes: 177 cases were in the skeletonized group, and 55 cases were in the nonskeletonized group. The differences of prognosis between the two groups were compared, and logistic regression models were used to analyze the factors affecting No.12 lymph node metastasis in the overall cohort and No.12b or No.12p lymph node metastasis in the skeletonized group.Results:A total of 232 patients were included, with 84 females (36.2%) and 148 males (63.8%), with an average age of 56.4±11.6 years. The proportion of female and ycT4 patients was significantly higher in the skeletonized group than in the nonskeletonized group (both P<0.05). Among all 232 patients, No. 12a metastasis occurred in 14 cases (6.0%). In the skeletonized group of 177 patients, No. 12b and No. 12p metastases were observed in 6 patients each (3.4%), and 4 patients had concurrent metastases in both No. 12b and No. 12a. The 5-year overall survival (OS) rates were 45.5% in the skeletonized group and 42.8% in the nonskeletonized group, with no statistical difference (HR=0.755, 95%CI: 0.488-1.168, P=0.580). The 5-year disease-free survival (DFS) rates were 39.8% and 41.0%, respectively, also with no statistical difference (HR=0.775, 95%CI: 0.513-1.172, P=0.584). 5-year OS for patients without No.12 lymph node metastasis was 48.8%, which was higher than the 15.9% for those with metastasis (HR=0.349, 95% CI: 0.209-0.584, P=0.003). Additionally, the 5-year DFS for those without metastasis was 44.3%, significantly higher than the 5.7% for those with metastasis (HR=0.444, 95%CI: 0.276-0.716, P<0.001). For patients without No. 12b or No. 12p lymph node metastasis, the 5-year OS was 47.6%, and the 5-year DFS was 42.3%, both of which were significantly higher than the 16.7% and 8.3% for those with No.12b or No. 12p lymph node metastasis, respectively (HR=0.353, 95%CI: 0.183-0.681, P=0.005; HR=0.457, 95%CI: 0.244-0.855, P=0.006). Multivariate analysis showed that more advanced ypN stage (OR=3.908, 95%CI:1.638-9.323, P=0.002) and tumor location in the lower stomach or whole stomach (OR=3.533, 95%CI: 1.312-9.511, P=0.012) were independent risk factors for No.12 lymph node metastasis and also for No.12b and No.12p lymph node metastasis (OR=2.426, 95%CI: 1.212-4.856, P=0.012 and OR=4.908, 95%CI:1.182-20.373, P=0.028, respectively). Conclusion:Patients with advanced gastric cancer who have more advanced ypN stage and tumor location in the lower stomach or whole stomach have a higher risk of No.12b and No.12p metastasis and thus require further skeletonized lymph node dissection of No.12.

Objective:To evaluate whether the mechanism by which mesenchymal stem cell-derived exosomes (MSC-exo) mitigated endotoxin-induced lung injury was related to the heme oxygenase-1 (HO-1)/mitochondrial signaling pathway in alveolar macrophages of mice.Methods:In vivo experiment Eighteen C57BL/6 wild-type (WT) mice were divided into 3 groups ( n=6 each) using a random number table method: control group (C group), lipopolysaccharide (LPS) group (L group) and LPS + MSC-exo group (LM group). Six HO-1 conditional knockout mice (HO-1 -/-) were selected and served as HO-1 -/- + MSC-exo + LPS group (HML group). The model of endotoxin-induced lung injury was prepared by injection of LPS 15 mg/kg. MSC-exo (2×10 11 particles) was intravenously injected at 1 h before injection of LPS in LM group. MSC-exo (2×10 11 particles) was intravenously injected and 1 h later LPS was injected in HML group. The expression of HO-1 in macrophages was detected using immunofluorescence, lung injury was assessed following hematoxylin-eosin staining, the wet/dry weight ratio (W/D ratio) was determined, and the mitochondrial morphology was observed with a transmission electron microscope. Cell experiment Alveolar macrophages (MH-S) were divided into 4 groups ( n=20 each) using a random number table method: control group (C group), LPS+ phosphate buffer solution group (LP group), LPS+ MSC-exo group (LM group), and LPS+ MSC-exo+ HO-1 small-interfering RNA group (LMS group). Cells were incubated for 12 h with LPS 10 μg/ml in LP, LM and LMS groups. In addition, LM group was incubated with MSC-exo 100 μg/ml, LP group was incubated with the equal volume of phosphate buffer solution, and the alveolar macrophages were transfected with HO-1 small interfering RNA and incubated with MSC-exo 100 μg/ml in LMS group at the same time. The concentrations of interleukin-1beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) in supernatant were measured by enzyme-linked immunosorbent assay, HO-1 expression was detected by Western blot, the mitochondrial membrane potential was measured using JC-1 staining, and the expression of reactive oxygen species (ROS) was detected by fluorescence. Results:In vivo experiment Compared to C group, the lung injury score and W/D ratio were significantly increased ( P<0.05), the fluorescence signal of HO-1 in macrophages was enhanced, and the damage to mitochondria was aggravated in L group. Compared to L group, the lung injury score and W/D ratio were significantly decreased ( P<0.05), the fluorescence signal of HO-1 in macrophages was enhanced, and the damage to mitochondria was reduced in LM group. Compared to LM group, the lung injury score and W/D ratio were significantly increased ( P<0.05), macrophages had no HO-1 fluorescence signal, and the damage to mitochondria was aggravated in HML group. Cell experiment Compared to C group, the concentrations of IL-1β and TNF-α in supernatant were significantly increased, the expression of HO-1 was up-regulated ( P<0.05), and the mitochondria predominantly exhibited green JC-1 fluorescence, accompanied by an enhanced ROS fluorescence signal in LP group. Compared to LP group, the concentrations of IL-1β and TNF-α in supernatant were significantly decreased, the expression of HO-1 was up-regulated ( P<0.05), and the mitochondria predominantly exhibited red JC-1 fluorescence, accompanied by a weakened ROS fluorescence signal in LM group. Compared to LM group, the concentrations of IL-1β and TNF-α in supernatant were significantly increased, the expression of HO-1 was down-regulated ( P<0.05), and the mitochondria predominantly exhibited green JC-1 fluorescence, accompanied by an enhanced ROS fluorescence signal in LMS group. Conclusions:The mechanism by which MSC-exo attenuates endotoxin-induced lung injury may be related to up-regulation of HO-1 expression in alveolar macrophages and reduction of mitochondrial damage in mice.
