Objective To investigate the effect of laser engraving personalized nasal patch applied to patients with nasal catheter indentation.Methods A total of 124 patients who underwent esophageal cancer surgery in the First Hospital of Lanzhou University from February 2022 to February 2023 and required indwelling nasal catheter were selected as study objects,and were divided into experimental group and control group according to random number table method,with 62 cases in each group.The control group used conventionally cut nasal patches to fix the nasal catheters,and the experimental group used laser engraved personalized nasal patches.Catheter displacement or slippage under the fixation device,nasal patch rolled edges and number of replacement,nasal medical device-related pressure injury,medical adhesive-related skin lesions and patients'comfort were observed in two groups.Results The rate of catheter displacement,number of rolled edges of nasal patches and numbers of replacement in experimental group were significantly lower than those in control group(P<0.05).The incidence of nasal mucosal indentation,nasal pain,nasal pressure injury and medical adhesive related skin lesions in experimental group were significantly lower than those in control group(P<0.05).The comfort of patients at the physiological level of experimental group was significantly better than that of control group(P<0.05).Conclusion Laser engraved personalized nasal patches can reduce the frequency of clinical nasal catheter displacement,nasal patch rolled edges and number of replacement,reduce the occurrence of nasal medical device related pressure injuries and medical adhesive-related skin lesions,and increase patients'comfort.

Objective To evaluate the efficacy of preoperative electroacupuncture intervention in promoting postoperative gastrointestinal functional recovery by meta-analysis.Methods The databases of PubMed,Cochrane Library,Web of Science,Embase,CBM,CNKI,VIP,and WanFang were searched systematically.The search period ranged from the inception of the databases to March 2024.Two researchers screened the literature independently,extracted the data,used Cochrane Risk of Bias tools to evaluate the quality of the inclusion study,and used RevMan 5.3 software for meta-analysis.Results Twelve RCTs were included,with 773 patients.There were 421 patients in the preoperative electroacupuncture group and 352 patients in the control group.The results of the meta-analysis showed that,time to first flatus(SMD=-0.56,95%CI-0.84 to-0.28,P＜0.001),time to first defecation(MD=-6.40 hours,95%CI-9.27 to-3.53,P＜0.001),time to bowel sound recovery(MD=-8.45 hours,95%CI-10.37 to-6.52,P＜0.001),time to first oral feeding(MD=-16.88 hours,95%CI-23.92 to-9.83,P＜0.001),the incidence of PONV(RR=0.75,95%CI 0.57 to 0.98,P=0.04)and length of hospital stay(MD=-0.78 d,95%CI-1.38 to-0.19,P=0.010)were significantly lower than the control group.Conclusion Electroacupuncture intervention before operation can effectively promote the recovery of post-operative exhaust,defecation,and bowel sound,shorten the time of fasting and drinking,reduce the inci-dence of PONV,shorten the length of hospital stay,and has good clinical value in promoting the recovery of postoperative gastrointestinal function.

Objective To investigate the effect of spleen on hepatic macrophages mediated activation of hepatic stellate cells(HSCs)in mice with liver fibrosis.Methods Eighteen male C57BL/6 mice were randomly divided into three groups.Mice in Group A and Group B were injected intraperitoneally with CCl4 to establish liver fibrosis mouse model,while those in Group C were injected with corn oil as normal control.Four weeks later,mice with liver fibrosis received splenectomy(Spx)or sham operation(Sham),respectively.After continuous injection for 2 weeks,liver homogenates(L-Homo)were prepared and liver cells were isolated from the three groups.Expressions of IL-1β,IL-13,TGF-β,TNF-α,PDGF-β and VEGF in the liver homogenates of the three groups were detected by Luminex multifactor analysis.The expressions of these cytokines in liver macrophages(L-Mψ)and other non-parenchymal cells of Sham and Spx mice were analyzed by Real-time quantitative PCR(RT-qPCR)and flow cytometry.Macrophage cell line RAW264.7 or bone marrow-derived macrophages(BMDMs)were treated with liver homogenates from the Sham and Spx groups.Then the differently treated RAW264.7 cells were analyzed for mRNA expressions of cytokines and glutamine metabolism-related molecules by RT-qPCR,or transwell co-cultured with hepatic stellate cell line JS1.After co-culture,the survival and extracellular matrix expression of JS1 cells were analyzed.For comparison,Student's t test(between two groups)or one-way analysis of variance(among multiple groups)were used.Results Compared with normal control group,the concentrations of IL-1β,IL-13,TGF-β and TNF-α in the L-Homo of model group were significantly increased and showed higher levels in Sham group than in Spx group.Moreover,the hepatic macrophages were indicated as the major source of these cytokines.Consistently,macrophages treated with liver homogenate of Sham mice had increased expressions of IL-1β,TGF-β and TNF-α and glutaminase(GLS).After co-culture with macrophages treated with liver homogenate of Sham group rather than Spx group,JS1 expressed higher expressions of α-SMA and collagens.Conclusion The spleen is involved in regulating the secretion of cytokines by hepatic macrophages and enhancing their ability to activate hepatic stellate cells.

Bone substitute material implantation has become an important treatment strategy for the repair of oral and maxillofacial bone defects. Recent studies have shown that appropriate inflammatory and immune cells are essential factors in the process of osteoinduction of bone substitute materials. Previous studies have mainly focused on innate immune cells such as macrophages. In our previous work, we found that T lymphocytes, as adaptive immune cells, are also essential in the osteoinduction procedure. As the most important antigen-presenting cell, whether dendritic cells (DCs) can recognize non-antigen biomaterials and participate in osteoinduction was still unclear. In this study, we found that surgical trauma associated with materials implantation induces necrocytosis, and this causes the release of high mobility group protein-1 (HMGB1), which is adsorbed on the surface of bone substitute materials. Subsequently, HMGB1-adsorbed materials were recognized by the TLR4-MYD88-NFκB signal axis of dendritic cells, and the inflammatory response was activated. Finally, activated DCs release regeneration-related chemokines, recruit mesenchymal stem cells, and initiate the osteoinduction process. This study sheds light on the immune-regeneration process after bone substitute materials implantation, points out a potential direction for the development of bone substitute materials, and provides guidance for the development of clinical surgical methods.

【Objective】 To investigate the central sedative and hypnotic effects and mechanisms of Shumian Capsule. 【Methods】 The blank control group, the positive drug diazepam group, and the low-, medium-, and high-dose groups of Shumian Capsule were designed in the experiments. Male Kunming mice were administered orally by gavage. We conducted the experiment of mouse autonomous activity, and assessed supra- and sub-threshold dose sleep with pentobarbital sodium, respectively. The levels of γ-aminobutyric acid (GABA) and glutamic acid (Glu) in the brain tissue of the mice were measured by enzyme-linked immunosorbent assay (ELISA) or colorimetric method. Male SD rats were injected intraperitoneally with p-chlorophenyl alanine [PCPA, 350 mg/(kg·d)] to establish an insomnia rat model, after which rats were continuously administered intragastrically for 7 days. The general status and body weight of the rats were observed. Total distance and standing times of rats were measured by open field test. Western blotting and immunohistochemistry assays were used to evaluate the protein expression of 5-HT1A receptor (5-HT1AR) in the rat hippocampus. 【Results】 Compared with the blank control group, the three dose groups of Shumian Capsule [1.6, 3.2, 6.4 mg/(kg·d)] for 14 consecutive days had significantly reduced the number of spontaneous activities and standing times in the mice (P<0.01). The high dose significantly prolonged the sleep duration of the mice induced by the supra-threshold dose of pentobarbital sodium (P<0.01). Compared with the blank control group, each dose group of Shumian Capsule had an increased GABA level in the mouse brain tissue in a dose-dependent manner (P<0.05); the medium- and high-dose groups had significantly reduced Glu levels in the hippocampus (P<0.05), while the high-dose group had significantly reduced Glu level in the cortex (P<0.05). In insomnia model rats, their activity was sluggish; their circadian activity rhythm disappeared; the hair became hard, rough and dull, with severe hair loss; and their weight reduced. After 7 consecutive days of the drug administration, the rats’ mental state in each Shumian Capsule dose group was improved. Compared with the blank control group, the rats’ body weight gains were significantly reduced after intraperitoneal injection of PCPA (P<0.01). Compared with the model group, each rat group of Shumian capsule treatment had significantly increased body weight gains (P<0.01). Compared with the blank control group, the distance of the rats in the model group increased in the open field test, and the expression level of 5-HT1AR protein in the hippocampus decreased. However, the distance of rats in diazepam group and each dose group of Shumian Capsule was significantly reduced (P<0.01), and the expression level of 5-HT1AR protein in the hippocampus of the high- and medium-dose groups of Shumian Capsule and diazepam group increased significantly (P<0.01). 【Conclusion】 Shumian Capsule has obvious effects of sedation, hypnosis and insomnia improvement, and its underlying mechanisms may be related to the increased GABA and decreased Glu contents in brain tissues, as well as up-regulated 5-HT1AR protein expression in the hippocampus.
