Objective:To investigate the clinical efficacy of strengthening the spleen to nourish the lung in treating stable chronic obstructive pulmonary disease (COPD) with lung and spleen qi deficiency complicated by sarcopenia. Methods:This study was designed as a prospective study. A total of 65 patients with stable COPD and sarcopenia who received treatment at Kunshan Hospital of Chinese Medicine from January 2021 to December 2021 were included in the study. They were randomly divided into a control group and an observation group using the random number table method. The control group ( n = 34) was treated with conventional therapy, while the observation group ( n = 31) was treated with Shenling Baizhu Powder, a traditional Chinese medication based on the principle of strengthening the spleen to nourish the lung, in addition to the conventional therapy given to the control group. Both groups were treated for 1 month. Traditional Chinese medicine syndrome score, pulmonary function, grip strength, walking speed, albumin and prealbumin levels were compared between the two groups. Results:After treatment, the scores of all traditional Chinese medicine syndromes in the observation group were significantly lower than those in the control group (all P < 0.05). Compared with the control group, the levels of forced expiratory volume in the first second (FEV 1)[(1.51 ± 0.27) L vs. (1.32 ± 0.20) L, t = 3.11, P < 0.001 ] and FEV 1/forced vital capacity (FVC) [(57.20 ± 8.41)% vs. (52.89 ± 5.66)%, t = 2.30, P = 0.025] were significantly higher in the observation group. Compared with before treatment, gait speed [(1.07 ± 0.27) m/s vs. (0.90 ± 0.30) m/s, t = 7.66, P < 0.001], grip strength [(20.62 ± 5.07) kg vs. (19.42 ± 5.78) kg, t = 3.55, P < 0.001], albumin [(231.38 ± 49.40) g/L vs. (200.26 ± 65.87) g/L, t = 3.70, P < 0.001] and prealbumin [(39.53 ± 3.45) g/L vs. (35.81 ± 4.46) g/L, t = 4.08, P < 0.001] levels in the observation group were significantly increased after treatment. There were no significant differences in gait speed, grip strength, albumin, and prealbumin levels in the control group before and after treatment (all P > 0.05). Conclusions:The method of strengthening the spleen to nourish the lung shows good clinical efficacy in treating stable COPD with lung and spleen deficiency complicated by sarcopenia, and it has great potential for broader application.

BACKGROUND:In most species,a bone defect that is longer than 1.5 or 2 times its diameter can be considered a critical bone defect,and when the bone defect volume reaches the critical value,it cannot heal on its own.Currently,there is no uniform standard for the size of critical-sized defects in the osteoporotic femoral condyle of rabbits.OBJECTIVE:To establish a rabbit model with different sizes of bone defects in the osteoporotic femoral condyle and to determine the critical-sized defects of osteoporotic femoral condyle in rabbits.METHODS:Thirty-six 3-month-old female New Zealand white rabbits were randomly divided into ovariectomy group(n=30)and sham operation group(n=6).Rabbits in the ovariectomy group underwent bilateral ovariectomy to establish an osteoporosis model,and then femoral condyle bone defect models of different diameters(diameters were 4,5,6,and 7 mm,and depths were 8 mm)were further established;rabbits in the sham operation group did not undergo ovariectomy.At 8 and 12 weeks after modeling,3 rats were randomly selected from each group for CT scanning and three-dimensional reconstruction to evaluate the healing of bone defects.Afterwards,samples were taken for gross observation and hematoxylin-eosin staining to observe the growth of new bone in the femoral condyle bone defect area.RESULTS AND CONCLUSION:(1)All rabbits survived and moved well after modeling of osteoporosis and femoral condyle bone defect.(2)At 12 weeks after osteoporosis modeling,dual-energy X-ray absorptiometry results showed that the bone mineral density of lumbar vertebrae in ovariectomy group was significantly lower than that in sham operation group(P＜0.05).Hematoxylin-eosin staining showed that the bone trabeculae in the ovariectomy group became thinner and sparse.The proportion of bone tissue area in the ovariectomy group was significantly lower than that in the sham operation group(P=0.00).Micro-CT results showed that the bone tissue parameters of the femoral condyle in the ovariectomy group were significantly different from those in the sham operation group(P＜0.05),and the ovariectomy group showed obvious characteristics of osteoporosis.(3)CT showed that the bone defect in the 4 mm and 5 mm diameter groups was basically completely repaired at 12 weeks after surgery.There was more new bone tissue in the 6 mm diameter group,but the central part of the bone defect was not completely repaired.A small amount of new bone tissue grew in the 7 mm diameter group,and the bone defect was obvious.(4)Gross observation at 12 weeks after surgery showed that the femoral condyle bone defect in the 4 mm and 5 mm diameter groups was completely repaired.Obvious depression was seen in the bone defect area of the 6 mm and 7 mm diameter groups,and the bone defect was not completely repaired.(5)Histological observation at 12 weeks after surgery showed that the bone defect area of the 4 mm and 5 mm diameter groups was completely filled with new bone,and the trabecular structure was irregular;while there were new trabeculae in the periphery of the 6 mm and 7 mm diameter groups,and the bone defect in the central area was still obvious.(6)The results showed that during the 12-week experimental observation period of osteoporotic femoral condyle defects in rabbits,under the condition of the same defect depth of 8 mm,femoral condyle defects with a diameter ≥ 6 mm could not heal on their own,while femoral condyle defects with a diameter＜6 mm were completely repaired.A diameter of 6 mm and a depth of 8 mm can be used as the critical bone defect value of osteoporotic femoral condyle in rabbits.

The objective of this study was to investigate whether Stenotrophomonas maltophilia(S.maltophilia)induces ferroptosis,a form of iron-dependent cell death,leading to an inflamma-tory response in RAW 264.7 macrophages by elevating oxidative stress levels.RAW 264.7 cells were stimulated with varying concentrations of S.maltophilia.The concentrations of TNF-αand IL-1β were quantified using ELISA kits to assess the impact of S.maltophilia on the inflammatory response in RAW 264.7 cells.The activities of glutathione(GSH)and malondialdehyde(MDA)levels were measured using GSH and MDA assay kits to evaluate changes in oxidative stress.West-ern blot analysis was employed to detect the expression levels of COX-2,xCT,GPX4,and other proteins involved in ferroptosis signaling pathways,thereby investigating the effect of S.malto-philia on ferroptosis in RAW 264.7 cells.The results demonstrated that S.maltophilia induced concentration-dependent increases in inflammation and oxidative stress in RAW 264.7 cells,up-regulated the expression of COX-2 protein and down-regulated the expression of xCT and GPX4.Pretreatment with the ROS inhibitor N-acetylcysteine(NAC)significantly mitigated the S.malto-philia-induced oxidative stress and ferroptosis signaling activation,thereby alleviating the inflam-matory response.Furthermore,treatment with the ferroptosis inhibitor Fer-1 directly suppressed the activation of the ferroptosis signaling pathway and reversed the inflammation induced by S.maltophilia.These findings suggest that S.maltophilia triggers inflammation in RAW 264.7 cells by activating the ferroptosis signaling pathway via an increase in oxidative stress levels.

Objective:To explore the adverse reactions and its risk factors during bowel preparation prior to colonoscopy.Methods:The clinical data of 1 727 patients who underwent colonoscopy at the First Affiliated Hospital of Air Military Medical University from September 2019 to March 2021 were analyzed retrospectively. The primary endpoint was the incidence of adverse reactions during bowel preparation. The risk factors of adverse reactions were identified by logistic regressions.Results:The incidence of overall adverse reactions was 54.9% (948/1 727). The incidences of nausea, vomiting, and abdominal discomfort were 38.6% (666/1 727) , 10.2% (177/1 727), 25.9% (447/1 727), respectively. Multivariate logistic regression analysis showed that being female ( OR=1.77, 95% CI: 1.45-2.17, P<0.001), history of abdominal surgery ( OR=1.38, 95% CI:1.08-1.75, P=0.009), inflammatory bowel disease ( OR=1.77, 95% CI: 1.08-2.91, P=0.024) were independent risk factors for adverse reactions during bowel preparation. Female gender ( OR=2.37, 95% CI: 1.66-3.38, P=0.001) and history of abdominal or pelvic surgery ( OR=1.45, 95% CI: 1.02-2.06, P=0.038) were independent risk factors for vomiting, while body mass index ≥25 kg/㎡( OR=0.48, 95% CI: 0.28-0.80, P=0.005) and age≥60 years ( OR=0.58, 95% CI: 0.38-0.89, P=0.013) were protective factors for vomiting during bowel preparation. Conclusion:A significant portion of patients experience adverse reactions during bowel preparation for colonoscopy. The risk factors of adverse reactions include female, history of abdominal surgery and inflammatory bowel disease. Female and a history of abdominal surgery are independent risk factors for vomiting, while obesity and old age are protective factors for vomiting during bowel preparation.

Objective To analyze the changes and clinical significance of aqueous humor stromal cell-de-rived factor-1(SDF-1),macrophage chemoattractant protein-1(MCP-1)and soluble adhesion molecule CD44(sCD44)in patients with diabetic cataract(DC).Methods A total of 80 patients with DC admitted to the hos-pital from January 2021 to January 2023 were selected as the DC group,and 40 patients with simple cataract during the same period were selected as the age-related cataract group.According to the stage of cataract,DC patients were divided into group A(incipient stage,32 cases),group B(intumescent stage,26 cases)and group C(mature stage and over mature stage,22 cases).According to the presence or absence of macular ede-ma after treatment,the patients were divided into occurrence group(20 cases)and non-occurrence group(60 cases).The levels of SDF-1,MCP-1 and sCD44 in each group were detected by enzyme-linked immunosorbent assay.The receiver operating characteristic curve and area under the curve(AUC)were used to analyze the value of SDF-1,MCP-1 and sCD44 levels in the diagnosis of DC.Results The levels of SDF-1,MCP-1 and sCD44 in the DC group were higher than those in the age-related cataract group(P<0.05),and the levels of SDF-1,MCP-1 and sCD44 in the A,B and C groups increased sequentially(P<0.05).The level of MCP-1 in the occurrence group was higher than that in the non-occurrence group(P<0.05).The AUC of MCP-1,sCD44 and SDF-1 in the diagnosis of DC was 0.869,and the diagnostic efficiency was better.Conclusion The changes of aqueous SDF-1,MCP-1 and sCD44 levels are related to the stage of cataract in DC patients.Dynam-ic monitoring of these three indexes,especially MCP-1,is helpful to judge the condition and prognosis of DC patients.

Objective To investigate the impact of Qizhi Jiangtang Capsule (QZJT) on renal damage in diabetic nephropathy (DN) mice via NOD like receptors family pyrin domain containing 3/caspase-1/ Gasdermin D (NLRP3/caspase-1/GSDMD) signaling pathway. Methods Mice were randomly allocated into six experimental groups: a normal control group (NC), a diabetic nephropathy model group (DN), a low-dose QZJT treatment group (L-QZJT), a high-dose QZJT treatment group (H-QZJT), a positive control group administered Shenqi Jiangtang Granules (SQJT), and an ML385 group (treated with an inhibitor of nuclear factor erythroid 2-related factor 2, Nrf2). Upon successful model induction, therapeutic interventions were commenced. Renal function impairment in the mice was evaluated through quantification of fasting blood glucose (FBG), 24-hour urinary albumin (UAlb), serum creatinine (SCr), blood urea nitrogen (BUN), and the kidney-to-body mass ratio (K/B). Renal tissue pathology was evaluated using HE and PAS staining. Serum levels of inflammatory cytokines IL-1β and IL-18 were quantified by ELISA. Levels of podocyte markers and proteins involved in relevant pathways were assessed using Western blot analysis. Results Compared with the NC group, FBG, 24 h UAlb, SCr, and BUN were increased in the DN group, and the K/B mass ratio was also increased. In contrast, compared with the DN group, FBG, 24 h UAlb, SCr, and BUN in both the low-dose (L-QZJT) and high-dose Quanzhou Jintang (H-QZJT) groups were decreased, and the K/B mass ratio was decreased as well. The therapeutic efficacy of H-QZJT was comparable to that of Shenqi Jiangtang Granules. QZJT ameliorated renal histopathological injury in DN mouse, increased the protein levels of Nephrin (a podocyte marker), and decreased the protein levels of NLRP3, apoptosis-associated speck-like protein containing CARD (ASC), pro-caspase-1, and GSDMD-N. After ML385 treatment, renal cells exhibited swelling and morphological changes, the inflammatory infiltrate area was enlarged, the protein levels of NLRP3, ASC, pro-caspase-1, and GSDMD-N were up-regulated, and the levels of IL-1β and IL-18 were increased. Conclusion QZJT may inhibit podocyte pyroptosis by acting on the Nrf2 to regulate the NLRP3/caspase-1/GSDMD pathway, thus improving renal damage in DN mouse.

Triple-negative breast cancer (TNBC) represents an aggressive breast cancer subtype with poor prognosis and limited targeted treatment options. This investigation examined the anti-cancer potential of Caerulomycin A (Cae A), a natural compound derived from marine actinomycetes, against TNBC. Cae A demonstrated selective inhibition of viability and proliferation in TNBC cell lines, including 4T1, MDA-MB-231, and MDA-MB-468, through apoptosis induction. Mechanistic analyses revealed that the compound induced sustained endoplasmic reticulum (ER) stress and subsequent upregulation of C/EBP homologous protein (CHOP) expression, resulting in mitochondrial damage-mediated apoptosis. Inhibition of ER stress or CHOP expression knockdown reversed mitochondrial damage and apoptosis, highlighting the essential role of ER stress and CHOP in Cae A's anti-tumor mechanism. Both oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) decreased in TNBC cells following Cae A treatment, indicating reduced mitochondrial respiratory and glycolytic capacities. This diminished energy metabolism potentially triggers ER stress and subsequent apoptosis. Furthermore, Cae A exhibited significant anti-tumor effects in the 4T1 tumor model in vivo without apparent toxicity. The compound also effectively inhibited human TNBC organoid growth. These results indicate that Cae A may serve as a potential therapeutic agent for TNBC, with its efficacy likely mediated through the disruption of glucose metabolism and the induction of ER stress-associated apoptosis.
