Objective:To compare minimally invasive surgery with traditional open surgery, analyze the current application status of health economic evaluations in the treatment of digestive tract cancers, such as esophageal cancer, gastric cancer, and colorectal cancer by minimally invasive surgery and provide evidence for the rational selection of clinical treatment, alleviation of disease-related economic burdens, and rational allocation of healthcare resources.Methods:By using five databases, i.e. China National Knowledge Infrastructure, Wanfang data, Chinese Biomedical Literature Database, PubMed, and Embase, a database was established to retrieve all the papers about health economic studies of minimally invasive surgery for esophageal cancer, gastric cancer, and colorectal cancer published until December 31, 2023. Literature was analyzed by using software NoteExpress 3.8, and data were processed using Excel 2021. The quality of included papers was evaluated using the CHEERS 2022 checklist, and Meta-analysis was conducted by using software Stata 17.0.Results:A total of 10 919 relevant papers were retrieved, and 59 studies were included. Only 14 studies (23.7%) used standard health economic evaluation methods. Meta-analysis results revealed no significant differences in direct medical expenditure and total expenditure between minimally invasive surgery and open surgery. However, the expenditure for minimally invasive surgery exhibited a significant increase [mean difference ( MD)=5 973.12 yuan, P<0.001], while hospital stay and indirect expenditure significantly decreased ( MD: -4.85 days and -733.79 yuan, P<0.001). In China, for gastric cancer, the direct medical expenditure of endoscopic surgery was lower than that of open surgery ( MD=-33 000.00 yuan) with no significant difference ( P<0.001). In colorectal cancer cases, the direct medical and surgical expenditures for laparoscopic surgery were higher than those for open surgery ( MD: 4 277.94 yuan and 4 267.80 yuan, P<0.001), while the indirect and total medical expenditures decreased ( MD: -768.34 yuan and -159.10 yuan). Hospital stays in patients who had minimally invasive surgery for all three types of cancer were shorter than those who had open surgery ( P<0.001). Conclusions:In the treatment of gastrointestinal cancer, compared with open surgery, minimally invasive surgery shows higher expenditure, but has advantages, such as shorter hospital stay and lower indirect expenditure, and there were no significant differences in direct medical and total expenditures between the two approaches. When conducting health economic evaluation, factors such as postoperative complications, hospital stay, and patient's economic status should be considered for their impact on total medical expenditure. It is necessary to pay attention to the application of health economic evaluations in healthcare decision-making.

Objective:To explore the role of the expression of peroxisome proliferator-activated receptor β/δ(PPARβ/δ)in the anti-inflammatory mechanism of acupuncture(AC)against cerebral ischemia-reperfusion injury(CIRI)in rat hippocampal tissue.Methods:A total of 60 SD rats were randomly divided into Sham group,CIRI group,CIRI+AC group and CIRI+AC+PPARβ/δsiRNA group.The CIRI rat model was prepared by the method of middle cerebral artery occlusion,and acupuncture treatment was used for intervention.The neurological function of rats was assessed by the modified neurological severity score(mNSS)method after 72 hours of intervention.The brain in-farction volume ratio was observed by 2,3,5-triphenyltetrazolium chloride(TTC)staining method.The pathological morphological changes of brain tissue were observed by hematoxylin-eosin(HE)staining.The expression levels of PPARβ/δ,IL-1β,and IL-10 mRNA in the hippocampal region were detected by RT-qPCR.Results:Compared with the Sham group,the mNSS scores and the brain infarction volume ratio in all modeling groups were significantly in-creased.Compared with the CIRI group,the mNSS scores and the brain infarction volume ratio in the CIRI+AC group were significantly reduced.The expression levels of PPARβ/δ and IL-10 in the hippocampus were significantly upregu-lated,while the expression level of IL-1β was significantly downregulated(P<0.01),with scattered inflammatory cell infiltration observed.Compared with the CIRI+AC group,there was no significant difference in the mNSS scores and the brain infarction volume ratio in the CIRI+AC+PPARβ/δsiRNA group.The expression level of PPARβ/δ in the hippocampus was significantly downregulated(P<0.01),while no significant difference was found in the expression level of IL-10 and IL-1β mRNA,with a small amount of inflammatory cell infiltration observed.Conclusion:Acupunc-ture ameliorates the recovery of neurological function and the ratio of cerebral infarction volume in rats with CIRI,and its mechanism may be associated with the upregulation of PPARβ/δ expression,thereby reducing inflammatory respon-ses and exerting neuroprotective effects.

Objective:To investigate the effects of acupuncture intervention on the expression of circRNA_017109 and miR-138-5p in the hippocampal region of rats with cerebral ischemia-reperfusion injury(CIRI),and to explore the potential mechanism of acupuncture in treating CIRI.Methods:Forty-five Sprague-Dawley(SD)rats were divided into sham group,middle cerebral artery occlusion/reperfusion(MCAO/R)group,and acupuncture(MCAO/R+AC)group.The MCAO/R and MCAO/R+AC groups were subjected to the modified Longa suture method to establish the MCAO/R model.The MCAO/R+AC group received acupuncture at the"Dazhui","Renzhong",and"Baihui"acu-points.Neurological impairment was assessed via the modified neurological severity score(mNSS).while cerebral infarct volume was assessed through TTC staining.Histological alterations in brain tissue were examined via HE stai-ning,and the expression of circRNA_017109 and miR-138-5p in the hippocampal area were determined using RT-qPCR.Results:The mNSS scores and cerebral infarct volume ratios in the model groups were markedly higher than those in the sham group(P<0.01),but these were significantly reduced in MCAO/R+AC group compared to the MCAO/R group(P<0.01).HE staining showed severe necrosis and inflammation in the MCAO/R group's hippocam-pus,while the MCAO/R+AC group had minimal necrosis and scattered inflammation.RT-qPCR results indicated that the expression of circRNA_017109 and miR-138-5p was downregulated in the MCAO/R group,while MCAO/R+AC group upregulated the expression of circRNA_017109 and miR-138-5p(P<0.05,P<0.01).Conclusion:Acupunc-ture can improve neurological deficits,reduce cerebral infarction volume,and alleviate inflammatory cell infiltration in CIRI rats by upregulating the expression of circRNA_017109 and miR-138-5p,thereby exerting neuroprotective effects.

Objective To investigate the therapeutic effects of bone marrow mesenchymal stem cells (BMSCs) for radiation-induced lung injury (RILI) and the underlying mechanism. Methods Forty-five healthy adult male C57BL/6 mice were randomly divided into control, model, and BMSCs groups. The model and BMSCs groups received a single irradiation dose of 20 Gy to the chest, while the control group did not receive X-ray irradiation. For the BMSCs group, an injection of 1 × 10⁶ BMSCs cells was administered via the tail vein within 6 h after irradiation. In the 5th week, the lung tissue was taken to observe pathological changes with HE staining; examine the expression of the inflammatory factors interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) with immunohistochemical staining; observe the polarization of macrophages with immunofluorescence staining; and measure the expression of the epithelial-mesenchymal transition markers E-cadherin, N-cadherin, and vimentin proteins by Western blot. Results After radiation, the model group developed pulmonary vasodilation and congestion with septal thickening and inflammatory cell infiltration, and these changes were markedly reduced in the BMSCs group. The model group showed significantly down-regulated expression of IL-6 and TNF-α compared with significantly increased levels in the model group (P < 0.01, P < 0.05). Treatment with BMSCs significantly increased the polarization of lung macrophages towards the M2 type, while significantly decreasing the abnormally increased N-cadherin and vimentin levels in RILI mice (P < 0.05, P < 0.01). Conclusion BMSCs have therapeutic effects for RILI mice, which may be through promoting macrophage polarization from M1 to M2.
