OBJECTIVE To study the effects of Sanchong tongluo sanjie formula on the proliferation and apoptosis of Lewis lung cancer cells. METHODS The rats were given Sanchong tongluo sanjie formula powder [0.946 g/(kg·d)], Sanchong tongluo sanjie formula decoction [2.730 g/(kg·d)], and normal saline intragastrically, and injected with Cisplatin injection (4.2 mg/kg) intra-peritoneally to prepare powder-containing serum, decoction-containing serum, positive control serum and negative control serum. Lewis lung cancer cells were divided into negative control serum group, positive control serum group, and 5%, 10%, 20% drug-containing serum groups. The cell proliferation inhibition rates at 24, 48, and 72 hours post- intervention were measured to screen the optimal intervention concentrations of powder-containing serum and decoction-containing serum. The cell invasion ability, metastasis ability and apoptotic rate were detected in the negative control serum group, positive control serum group, 20% powder-containing serum group, and 20% decoction-containing serum group. Protein expressions of vascular endothelial growth factor (VEGF), hypoxia-inducible factor-1α (HIF-1α), prolyl hydroxylase-2 (PHD2), matrix metalloproteinase-2 (MMP-2), extracellular regulated protein kinases (ERK),c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (p38 MAPK) were detected. RESULTS The cell proliferation inhibition rates for both the 20% powder-containing serum group and the 20% decoction-containing serum group, when intervened for 48 hours, were not less than 50%. Compared with negative control serum group, the number of invasive Lewis lung cancer cells and migration distance were decreased significantly, while the apoptotic rate was increased significantly (P<0.05); the apoptotic rate in the 20% powder- containing serum group was significantly higher than 20% decoction-containing serum group (P<0.05). The protein expressions of PHD2 and p38 MAPK were increased significantly in the 20% powder-containing serum group (P<0.05), while the protein expression of HIF-1α was decreased significantly in the 20% decoction-containing serum group (P<0.05). CONCLUSIONS Sanchong tongluo sanjie formula can inhibit the proliferation, invasion and metastasis of Lewis lung cancer cells while promoting their apoptosis. The mechanism of action may be related to regulating the PHD2/HIF-1α signaling pathway. Furthermore, the powder demonstrates superior efficacy compared to the decoction, suggesting that they may possess different mechanisms of action.

Sarcopenia is a clinical syndrome characterized by a decrease in skeletal muscle strength and quality, often accompanied by adverse outcomes such as falls, loss of function and weakness. The pathogenesis of sarcopenia is complex, and studies have shown that dysfunction due to impaired mitochondrial quality control is an important pathological factor in the occurrence and development. Traditional Chinese medicine(TCM) has been widely favoured for regulating mitochondrial homeostasis and preventing sarcopenia by virtue of its multi-target and multi-pathway advantages. They can play a role in the prevention and treatment of sarcopenia by regulating the mitochondrial quality control system to inhibit the occurrence of mitochondrial oxidative stress, regulate the balance of mitochondrial dynamics, inhibit mitochondrial autophagy, promote mitochondrial biosynthesis, resist the occurrence of mitochondrial apoptosis, and maintain the mitochondrial calcium and protein homeostasis. Based on this, the paper reviewed the relationship between mitochondrial quality control and sarcopenia, as well as the mechanism of TCM in intervening the mitochondrial quality control system to treat sarcopenia, in order to provide a new idea for the prevention and treatment of sarcopenia by TCM and to a theoretical basis for the clinical research on TCM intervention in sarcopenia.

ObjectiveTo explore the incremental cost of central line-associated bloodstream infections (CLABSI) after central venous catheterization (CVC) in critically ill patients in the intensive care unit (ICU), as well as the main cost of nosocomial infection prevention and control. By comparing these two costs, the medical personnel to pay more attention should CLABSI prevention and control from the perspectives of medical quality and economic benefits, and promote the implementation of prevention and control measures. MethodsCluster sampling was used to select 126 critically ill patients who underwent CVC in the ICU of a tertiary traditional Chinese medicine hospital from January 2021 to December 2023, including 65 cases in the CLABSI group and 61 in the non-CLABSI group. Patients’ data were retrospectively collected from the hospital medical records, including the disease type, gender, age, length of hospital stay, outcome, and hospitalization expenses. The costs of different hand hygiene methods and differing approaches to environmental cleaning and disinfection were analyzed and compared. ResultsThere were significant differences in the length of hospital stay (Z=-5.35, P<0.05) and total hospitalization expenses (Z=-6.79, P<0.05) between the CLABSI and non-CLABSI group. Total hospitalization expenses showed significant differences among patients with different lengths of hospital stay (H=43.01, P<0.05), with much higher median one in those with 60 or more days of hospital stay than other patients. Greater differences of median total hospitalization expenses were found in males than in females (Z=-3.98, P<0.05), as well as in patients aged 60-80 years than in patients of other ages (Z=-5.79, P<0.05). ConclusionsThe occurrence of CLABSI significantly increases the ICU patients’ length of hospital stay and hospitalization expenses. There are differences in the costs of different hand hygiene methods and differing approaches to environmental cleaning and disinfection, but these costs are acceptable compared to the incremental costs directly attributable to CLABSI. Therefore, medical institutions should attach importance to the investment in prevention and control of nosocomial infections such as hand hygiene and environmental cleaning and disinfection, formulate practical, reasonable and feasible plans, and ensure their implementation, in order to avoid nosocomial infections, improve the medical quality, effectively control patients’ length of hospital stay and hospitalization costs, and strive to maintain patient safety.

The study was carried out to understand the changes in the ethical cognition status of laboratory animals and the effectiveness of laboratory animal ethics education among medical students in Xiangya School of Medicine of Central South University (CSU), and provide new enlightenment for further strengthening the ethical education of laboratory animals. In the study, the same self-compiled questionnaire was used to investigate the ethical cognition of experimental animals among medical students in Xiangya School of Medicine of CSU in 2011 and 2021, and 359 and 363 questionnaires were collected respectively. Through comparative analysis of the questionnaire results before and after ten years, it was found that medical students’ animal experiment operation and attitudes towards laboratory animals, cognition of experimental animal ethics knowledge and their attitude to animal experiment ethics education were significantly improved. It showed that the state of experimental animal ethics cognition among medical students in Xiangya School of Medicine of CSU had improved significantly in recent 10 years, but the cognition of experimental animal ethics knowledge was higher than the actual behavior of caring for experimental animals, and there was the phenomenon of "separation of knowledge and action". The ethics education of experimental animals needs to pay more attention to the development of students’ behavior of caring for experimental animals.

ObjectiveTo provide technical support for the molecular surveillance of pathogenic bacteria strains carrying mobile colistin resistance-1 (mcr⁃1) gene isolate from inlet of wastewater treatment plants (WWTP). MethodsThe Enterobacteriaceae strains carrying mcr⁃1 resistance gene isolate from inlet of WWTP during April 1 to June 30, 2023 in Shanghai were cultured on blood-rich and SS culture medium and were identified using a mass spectrometry analyzer. The mcr⁃1 gene and copy number were detected by real-time fluorescence quantitative PCR. Drug susceptibility test was performed by microbroth dilution method. The copy numbers of Escherichia coli carrying mcr⁃1 gene isolated from wastewater and human fecel were statistically analyzed by SPSS 25.0. ResultsA total of 14 strains carrying the mcr⁃1 gene were isolated from 49 WWTP samples, and the positive isolation rate was 28.6%, including 12 non-diarrheal E. coli strains and 2 Klebsiella pneumoniae strains. The drug susceptibility results showed that all 14 strains were multi-drug resistant bacteria. They were all sensitive to imipenem and tigecycline, but were ampicillin- and cefazolin-resistant. There was no significant difference in the copy number between human-sourced diarrheal E. coli and wastewater-sourced non-diarrheal E. coli (t=0.647, P>0.05). ConclusionThe isolation and identification of strains carrying the mcr⁃1 gene from inlet of WWTP samples were firstly established in Shanghai. The multi-drug resistance among the isolated strains is severe. To effectively prevent and control the spread of colistin-resistant bacteria, more attention should be paid to the surveillance of mcr⁃1 gene.

ObjectiveThis study aimed to observe the impact of sinomenine hydrochloride on the proliferation of fibroblasts and the mRNA expression of related genes in knee joint adhesion and contracture in rabbits. Additionally, we sought to explore its potential mechanisms in combating knee joint adhesion and contracture. MethodsFibroblasts were cultured in vitro, and experimental groups with varying concentrations of sinomenine hydrochloride were established alongside a control group. Cell proliferation was assessed using the CCK-8 assay. Changes in the mRNA expression of fibroblast-related genes following sinomenine hydrochloride treatment were evaluated using RT-qPCR. The impact of the drug on serum levels of inflammatory cytokines was determined using the ELISA method, and the expression of related proteins was assessed using Western blot. ResultsSinomenine hydrochloride was found to inhibit fibroblast viability, with viability decreasing as the concentration of sinomenine hydrochloride increased. The effects of sinomenine hydrochloride in all experimental groups were highly significant (P<0.05). At the mRNA expression level, compared to the control group, sinomenine hydrochloride led to a significant downregulation of inflammatory cytokines in all groups (P<0.05). Additionally, the expression levels of apoptosis-related proteins significantly increased, while Bcl-2 mRNA expression decreased (P<0.05). The mRNA expression levels of the PI3K/mTOR/AKT3 signaling pathway also decreased (P<0.05). At the protein expression level, in comparison to the control group, the levels of inflammatory cytokines IL-6, IL-8, IL-1β, and TGF-β were significantly downregulated in the middle and high-dose sinomenine hydrochloride groups (P<0.05). The expression levels of cleaved-PARP, cleaved caspase-3/7, and Bax increased and were positively correlated with the dose, while the expression levels of the anti-apoptotic protein Bcl-2 and the PI3K/AKT3/mTOR signaling pathway were negatively correlated with the dose. Sinomenine hydrochloride exhibited a significant inhibitory effect on the viability of rabbit knee joint fibroblasts, which may be associated with the downregulation of inflammatory cytokines IL-6, IL-8, and IL-1β, promotion of apoptosis-related proteins cleaved-PARP, cleaved caspase-3/7, and Bax, suppression of Bcl-2 expression, and inhibition of gene expression in the downstream PI3K/AKT3/mTOR signaling pathway. ConclusionSinomenine hydrochloride can inhibit the inflammatory response of fibroblasts in adhesive knee joints and accelerate fibroblast apoptosis. This mechanism may offer a novel approach to improving and treating knee joint adhesion.
