This study aimed to investigate the effects of the peptide secreted protein isthmin-1 (ISM1) on the proliferation and apoptosis of non-small cell lung cancer (NSCLC) cells. ISM1 expression in NSCLC was detected by immunohistochemistry (IHC). ISM1 was overexpressed in lung cancer cell lines by transient transfection of ISM1 plasmids, or establishing ISM1 overexpression stable cell lines, or by treating cells with recombined ISM1 (rISM1). CCK-8 was used to examine cell growth. The intracellular signal transduction pathways regulated by rISM1 were analyzed by transcriptome sequencing, and verified by qRT-PCR and Western blot. The levels of intracellular ROS and apoptosis were further detected using the kit. The results showed that the expression of ISM1 was decreased in human NSCLC tissue samples compared to normal lung tissue samples. Overexpression of ISM1 or rISM1 treatment significantly suppressed the growth of lung cancer cells. RNA sequencing revealed that rISM1 mainly regulated the FoxO signaling pathway. rISM1 treatment decreased the expression of FoxO3 and FoxO1, increased reactive oxygen species (ROS) production, and induced cell apoptosis. These results suggest that ISM1 can inhibit the growth of NSCLC by regulating the FoxO signaling pathway. These findings provide new strategies for cancer therapy.

ObjectiveTo explore the potential mechanism of acupuncture with the method of soothing the liver and regulating the mind in improving depressive disorder. MethodsEighteen C57BL/6J mice were randomly divided into blank group, model group, and acupuncture group, with 6 mice in each group. The model group and the acupuncture group were subjected to depression induction by intraperitoneal injection of lipopolysaccharide (LPS), while the blank group received an equal volume of normal saline once daily for seven consecutive days. Concurrently, the acupuncture group received "soothing the liver and regulating the mind" acupuncture intervention starting from the first day of modeling, once daily for 14 days; whereas the blank group and the model group were only restrained without acupuncture. The sucrose preference test was used to assess sucrose preference rate, the open-field test to measure center stay time and total travel distance, and the forced swim test to evaluate immobility time. Hematoxylin-eosin (HE) staining was performed to observe hippocampal morphological changes. Enzyme-linked immunosorbent assay (ELISA) was used to detect levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in hippocampal tissue. Western blot analysis was conducted to examine the protein expression levels of Toll-like receptor 4 (TLR4) and nuclear factor-κB (NF-κB) in the hippocampus. ResultsCompared to the blank group, the model group showed a significant reduction in sucrose preference rate, center stay time, and total travel distance, along with a significant increase in immobility time in the forced swim test, hippocampal IL-1β, IL-6, and TNF-α levels, as well as TLR4 and NF-κB protein expression (P<0.01), and the histological examination revealed blurred hippocampal neuronal boundaries, loose arrangement, and some neurons exhibiting nuclear pyknosis and deep staining. Compared to the model group, the acupuncture group demonstrated a significant increase in sucrose preference rate, center stay time, and total travel distance, along with a significant reduction in immobility time in the forced swim test, hippocampal IL-1β, IL-6, and TNF-α levels, and TLR4 and NF-κB protein expression (P<0.01), and the histological analysis showed that hippocampal neurons in the acupuncture group were more tightly arranged, with reduced nuclear pyknosis and deep staining. ConclusionAcupuncture with the "soothing the liver and regulating the mind" method can significantly improve depression-like behavior, potentially by inhibiting the hippocampal TLR4/NF-κB signaling pathway and alleviating inflammatory responses.

Objective:
To investigate the effects of "liver-smoothing and spirit-regulating" acupuncture on the intestinal flora, lipopolysaccharide (LPS) and the hippocampal toll-like receptor 4 (TLR4)/ transcription factor (NF)-κB signaling pathway in depressive disorder mouse model, and to explore its underlying mechanisms.
Methods:
Eighteen male SPF-grade C57BL/6J mice were randomly assigned to the control, model, and acupuncture groups using a random number method, with six mice in each group. The depression disorder model was induced in mice from both the acupuncture and model groups using CUMS. The mice in the acupuncture group were treated with acupuncture at the acupoints of "Baihui" (DU20), "Yintang" (DU29), "Hegu" (LI4), and "Taichong" (LR3) on the 15th day of modeling, with a duration of 20 min per session, once per day, for 2 consecutive weeks. Behavioral differences were assessed using the sucrose preference test, open field test, and forced swim test. Hematoxylin-eosin staining was used to observe pathological changes in the hippocampus and colon. The levels of the inflammatory factors interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, and LPS in the hippocampus and colon were measured using Enzyme-linked Immunosorbent Assay. Western blotting was used to detect the expression of TLR4 and NF-κB protein in the hippocampus. Changes in gut microbiota structure and abundance were analyzed by 16 S rDNA sequencing.
Results:
Compared to the control group, the model group showed reduced sucrose preference rate, time in the center area, and total distance, with an increase in immobility time (P<0.01). Inflammatory pathological changes were observed in the hippocampal CA1 region and colon. The contents of IL-1β, IL-6, TNF-α, and LPS in the hippocampus and colon increased (P<0.01). The protein expression levels of hippocampal TLR4 and NF-κB were increased (P<0.01). The Chao1 index was increased (P<0.01). The relative abundances of Pseudomonadales, Acinetobacter, Moraxellaceae, Solibacillus, Escherichia_shigella, Enterobacteriaceae, Enterobacterales, Dubosiella, and Erysipelottichales were decreased, while the relative abundances of Alloprevotella and gram_negative_bacteriurh_cTPY_13 were increased (P<0.05). The pathways of lipopolysaccharide biosynthesis and pathogenic Escherichia coli infection were upregulated, and the pathway of terpenoid backbone biosynthesis was downregulated (P<0.01). Compared to the model group, the acupuncture group showed increased sucrose preference, time in the center area, and total distance, with a decrease in immobility time (P<0.01). The inflammatory pathological changes in the hippocampal CA1 region and colon were alleviated. The contents of IL-1β, IL-6, TNF-α, and LPS in the hippocampus and colon were reduced(P<0.01). The protein expression levels of hippocampal TLR4 and NF-κB were reduced (P<0.01). The Chao1 index was decreased (P<0.05), and the relative abundances of Dubosiella and Erysipelotrichaceae were increased, while the relative abundance of Rikenellaceae, Alloprevotella, and gram_negative_bacteriuch_cTPY_13 were decreased(P<0.05). The pathways of lipopolysaccharide biosynthesis and pathogenic Escherichia coli infection were significantly downregulated, and the pathway of terpenoid backbone biosynthesis was upregulated (P<0.01).
Conclusion
" Liver-smoothing and spirit-regulating" acupuncture can improve depressive symptoms in depressive disorder mice, potentially through regulating the LPS and TLR4/NF-κB signaling pathway mediated by intestinal flora, reducing the inflammatory response of the hippocampus, and improving the pathological injury of the hippocampus.

The paper reviews systematically Professor FU Wenbin's academic thinking and clinical experience of integrative acupuncture-moxibustion therapy for cranial tinnitus. Professor FU believes that cranial tinnitus refers to psychosomatic comorbidity. This disease is associated mainly with the brain and liver in terms of the disease location. In pathogenesis, the dysfunction of qi movement, disharmony of internal organs and unhealthy conditions of body and mind are involved. In treatment, based on psychosomatic medicine, from the perspective of the integration of body and mind, and in line with the mode of the integrative acupuncture-moxibustion therapy, holistic regimens are used, including acupuncture, moxibustion, auricular acupuncture, etc. to consolidate the therapeutic effect of "tranquilizing the mind and relieving tinnitus".

Objective:To predict pre-treatment clinical parameters that are associated with poor response and prognosis to ursodeoxycholic acid (UDCA) in patients with primary biliary cholangitis (PBC) and to use second-line treatment drugs in the early stages to delay the progression of the disease so that patients can benefit from early-stage treatment.Methods:Patients diagnosed with PBC at the Second Affiliated Hospital of Kunming Medical University from 2013 to 2022 were collected. Two hundred fifty-seven cases were screened in accordance with the inclusion and exclusion criteria. The response and prognosis conditions one year after treatment were followed up in outpatient and inpatient departments, as well as through telephone calls. Statistical analyses were performed using t-tests, Mann-Whitney U test, χ2 test, Fisher's exact test, and logistic regression analysis according to different data. Results:A total of 257 PBC cases were included, with 223 females (86.80%) and 34 males (13.20%). Univariate and multivariate binary logistic regression analyses showed that baseline high albumin levels [odds ratio ( OR): 0.882, 95% confidence interval ( CI): 0.805~0.967, P=0.008] were a protective factor for PBC patients' response to UDCA treatment after adjusting for different confounding factors, while baseline high alkaline phosphatase ( OR: 1.012, 95% CI: 1.008~1.016, P<0.001) and baseline high neutrophil/lymphocyte ratio (NLR) level ( OR: 1.462, 95% CI:1.079~1.981, P=0.014) were risk factors for a poor response to UDCA. Trend analysis showed that the baseline NLR quantile was positively correlated with the risk of poor response to UDCA ( OR: 5.512, 95% CI: 1.040~29.216, P=0.045) in patients with PBC. Cox proportional hazards regression analysis identified that age [hazard ratio ( HR): 1.050, 95% CI: 1.019~1.082] and NLR value ( HR:1.089, 95% CI:1.021~1.161) were independent influencing risk factors for all-cause mortality in PBC patients ( P<0.05). Conclusion:Baseline high albumin levels are protective factors against a poor biochemical response to UDCA, while baseline high alkaline phosphatase levels and high NLR are risk factors for a poor biochemical response to UDCA in patients with PBC. Additionally, baseline high NLR values are positively correlated with poor biochemical response to UDCA treatment.

Objective:To investigate the effects of the expanded lateral thoracic artery perforator flap in the reconstruction of breast scar contracture deformity after burns in minor females.Methods:The study was a retrospective observational study. From July 2018 to October 2023, 8 female children aged 4 to 12 years and with breast scar contracture deformity after burns, who met the inclusion criteria, were admitted to the Department of Burns and Plastic Surgery of Guangzhou Red Cross Hospital of Jinan University. The skin and soft tissue expander (hereinafter referred to as expander) was placed in the first stage. The contracture scar was removed and released in the second stage, and the wound formed after the scar was removed measured between 9 cm×8 cm and 15 cm×10 cm. The expanded lateral thoracic artery perforator flap was designed and transferred to repair the wound with resected flap area of 10 cm×9 cm to 16 cm×11 cm, and the wound at the flap donor area was directly sutured. The complications such as incision infection, hematoma, and expander exposure were observed after stage Ⅰ surgery. After stage Ⅱ surgery, the survival of the flap and the wound healing at the flap donor area were observed. During the 1-year follow-up after the stage Ⅱ surgery, the breast development was evaluated according to tanner staging performance of female pubertal breast development, the aesthetic effect of the affected breast was evaluated by using the aesthetic effect evaluation standard after breast surgery, the Vancouver scar scale (VSS) was used to score the scar condition at the flap donor and recipient areas, and the satisfaction of the children's families with the surgical outcomes was investigated by using a self-made scale.Results:After stage Ⅰ surgery, no incision infection, hematoma, expander exposure, or other complications occurred in 8 children. After stage Ⅱ surgery, only one child had tissue necrosis at the distal end of the flap with a size of about 2 cm×1 cm, which healed after dressing change, and the flap in other children had good blood supply, soft texture, moderate thickness, and similar color to the skin at the recipient area. The wounds at all flap donor areas healed well. During the 1-year follow-up after stage Ⅱ surgery, 7 children had normal breast development, with their breast volume, height, and shape being almost the same as or similar to the healthy side, with the aesthetic effect of all being grade Ⅰ; the breast in one child had not yet developed, and these indicators were not evaluated. The locations of nipple areola complex in 8 children were almost the same as or similar to those in the healthy side, and their skin color, integrity, texture, and elasticity of the partial breast repaired by the transferred flap were similar to those in the healthy side, with the aesthetic effect of all being grade Ⅰ. The shapes of nipple and areola in 5 children were inconsistent with those in the healthy side because of the original scar, with the aesthetic effect of all being grade Ⅱ, and the shapes of nipple and areola in the other 3 children were consistent with those in the healthy side, with the aesthetic effect of all being grade Ⅰ. The VSS score of the scar at the flap recipient area was 2-5, and the VSS score of the scar at the flap donor area was 1-3. Seven children's families were satisfied with the surgical effect, and one child's family was basically satisfied with the surgical effect.Conclusions:For the breast scar contracture deformity of minor females after burns, the expanded lateral thoracic artery perforator flap is used for reconstruction before puberty, which results in fewer postoperative complications, good breast shape, and hidden scar at the flap donor area. It is beneficial for the normal development of adolescent breasts, and is one of the safe and effective methods for the treatment of breast scar contracture deformity in minor females after burns.

Objective:To establish a portable gastrointestinal endoscopy telemedicine platform that enables the real-time transmission of endoscopy audio and video data to the consulting physicians through 5G communication technology, and to evaluate the effectiveness of this platform.Methods:From October 10 to October 20, 2023, 30 cases (16 cases from Sanya, Hainan Province, and 14 cases from Zhanjiang, Guangdong Province) from primary health institutions were selected for portable gastrointestinal endoscopy telemedicine consultations with a tertiary hospital in Shanghai. 5G network transmission parameters were recorded, and the lesion detection rate of the examination side and the consultation side, as well as the quality of the videos and images were compared.Results:The 5G network transmission parameters for telemedicine from Sanya and Zhanjiang to Shanghai included download network speeds of 168.3 Mbps and 160.4 Mbps, upload network speeds of 75.1 Mbps and 72.4 Mbps, and delays of 28 ms and 25 ms, respectively. There was no significant difference in the lesion detection rate [43.3% (13/30) VS 36.7% (11/30), χ2=0.792, P=0.598] between the physicians on the examination side and the consultation side. The endoscopic video quality (2.92±0.59 points VS 2.88±0.64 points, t=0.302, P=0.763) and picture quality (3.10±0.57 points VS 3.05±0.53 points, t=0.424, P=0.622) were compared by two senior endoscopists between the examination side and the consultation side, indicating no significant difference. Conclusion:The utilization of portable gastrointestinal endoscopy for telemedicine based on 5G network technology is effective in enabling telemedicine consultations and providing operational guidance. This approach enhances the procedural skills and diagnostic capabilities of physicians in primary healthcare settings, facilitating the equitable distribution of high-quality medical resources.

Coronavirus-related diseases pose a significant challenge to the global health system. Given the diversity of coronaviruses and the unpredictable nature of disease outbreaks, the traditional "one bug, one drug" paradigm struggles to address the growing number of emerging crises. Therefore, there is an urgent need for therapeutic agents with broad-spectrum anti-coronavirus activity. Here, we provide evidence that ATV006, an anti-SARS-CoV-2 nucleoside analog targeting RNA-dependent RNA polymerase (RdRp), has broad antiviral activity against human and animal coronaviruses. Using mouse hepatitis virus (MHV) and human coronavirus NL63 (HCoV-NL63) as a model, we show that ATV006 has potent prophylactic and therapeutic activity against murine coronavirus infection in vivo. Remarkably, ATV006 successfully inhibits viral replication in mice even when administered 96 h after infection. Due to its oral bioavailability and potency against multiple coronaviruses, ATV006 has the potential to become a useful antiviral agent against SARS-CoV-2 and other circulating and emerging coronaviruses in humans and animals.
