ObjectiveTo investigate the anti-inflammatory, antioxidant, and goblet cell-stimulating effects of a suspension of Ophiopogon japonicus (L. f.) Ker Gawl. (O. japonicus, Mai Dong) extract combined with hyaluronic acid (HA) in the mouse model with dry eye disease (DED).MethodsA DED mouse model was induced using benzalkonium chloride (BAK), followed by treatment with O. japonicus extract-containing eye drops at varying concentrations. Experimental groups included a normal control, a DED model control, a positive control, and an O. japonicus extract-treated group. Corneal fluorescein staining and tear break-up time (TBUT) were used to assess tear film stability and ocular surface integrity. Enzyme-linked immunosorbent assay (ELISA) measured inflammatory factor levels in corneal and conjunctival tissues, whereas Western blot (WB) analyzed key antioxidant and inflammatory markers, including nuclear factor erythroid 2-related factor (2Nrf2) and heme oxygenase 1 (HO-1). Periodic acid-schiff (PAS) staining and immunofluorescence were used to evaluate goblet cell density and mucin secretion.ResultsO. japonicus extract significantly improved corneal damage, reduced fluorescein staining scores, prolonged TBUT, and increased tear secretion. It downregulated inflammatory markers, including interleukin-8 (IL-8), interleukin-1β (IL-1β), and interferon-γ (IFN-γ) while upregulating Nrf2, HO-1, and the interleukin-13 (IL-13)/IFN-γ ratio, alleviating oxidative stress and inflammation. PAS staining showed increased conjunctival goblet cell density and restored mucin secretion, enhancing tear film stability.ConclusionO. japonicus extract demonstrated significant anti-inflammatory, antioxidant, and goblet cell-stimulating effects in a DED model, with good biocompatibility and promising therapeutic potential. Future research should optimize extraction processes and validate their efficacy and safety in clinical settings.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To study on the effect of ultrasound-guided thoracic paravertebral nerve (TPVB) block on quality of recovery from general anesthesia in tuberculosis patients with fiberboard exfoliation in post anesthesia recovery unit (PACU).Methods:From May 2018 to December 2019, 40 tuberculosis patients in Changsha Central Hospital with pulmonary fibreboard exfoliation and focal abscess lesions cleaning were randomly divided into two groups, with 20 patients in each group. The patients in group A received endobronchial general anesthesia and in group B received ultrasound-guided TPVB combined with endobronchial general anesthesia. Patients in the two groups were maintained under anesthesia by propofol, and the bispectral index (BIS) was maintained within the range of 40-50. The dosage of propofol and sufentanil was adjusted according to changes in BIS and hemodynamics. The mean arterial pressure (MAP), heart rate (HR) in two groups of patients were recorded at before anesthesia induction (T 0), before cutting leather (T 1), cut skin after (T 2), the end of operation (T 3), extubation time (T 4), and T 5 (time of leaving PACU). The visual analogue scale (VAS) of all patients in resting and cough state was recorded at 5, 30 min after extubation and the time of leaving PACU. The dosage of propofol and sufentanil in the operation and the additional dosage of sufentanil in PACU were recorded in both two groups. And the respiratory recovery time, consciousness recovery time, extubation time and sedation agitation scale(SAS) were observed. The adverse reactions such as nausea, vomiting, drowsiness and hypotension were observed in PACU. Results:Compared with group A, MAP and HR of patients at T 2, T 3, T 4, T 5 in group B were more stable during anesthesia, and VAS of patients in group B were lower than that in group A at each time point after extubation ( P<0.05). The dosage of sufentanil and propofol in group B were (35.92±8.12)μg and (749.56±95.30)mg respectively, which were significantly lower than those in group A [(45.74±4.42)μg and (862.83±105.34)mg, P<0.05]; the dosage of sufentanil in postoperative anesthesia recovery room of group B was (5.26±2.10)μg, significantly less than that of group A (10.35±5.86)μg ( P<0.05). The respiratory recovery time, consciousness recovery time and extubation time in group B were (12.92±5.12) min, (20.56±5.10) min and (26.87 ± 6.16) min, which were shorter than those in group A [(15.74±4.72)min, (25.83±5.34)min and (35.35±5.80)min, P<0.05]. The incidence of postoperative nausea, vomiting, lethargy and hypotension in group B were 10%, 10%, 35% and 20%, which were significantly lower than those in group A (30%, 20%, 75% and 45%, P<0.05). Conclusions:Ultrasound-guided paravertebral nerve block may significantly reduce the dosage of opioid analgesics for general anesthesia in tuberculosis patients with fiberboard exfoliation, accelerate the speed of anesthesia recovery, reduce the agitation during recovery, and improve the quality of anesthesia recovery.

Objective: This study aims to analyze factors associated with lymphovascular space invasion (LVSI) and evaluate the prognostic significance of LVSI in Chinese endometrioid endometrial cancer (EEC) patients. Methods: Five-hundred eighty-four EEC patients undergoing surgery in our center from 2006 to 2016 were selected for analysis. Univariate analysis and multivariate logistic regression were used to examine relevant factors of LVSI. To evaluate the prognostic role of LVSI, survival analyses were conducted. In survival analyses, both multivariate Cox regression and propensity score matching were used to control the confounders. Results: The incidence of LVSI was 12.16% (71/584). Diabetes history (p=0.021), lymph node metastasis (p=0.005), deep myometrial invasion (p<0.001) and negative PR expression (p=0.007) were independently associated with LVSI. Both Kaplan-Meier method and univariate Cox regressions showed LVSI negative and positive cases had similar tumor-specific survival (TSS) and disease-free survival (DFS). After adjusting for the influence of adjuvant therapy and other clinicopathological factors with multivariate Cox regressions, LVSI still could not bring additional survival risk to the patients (p=0.280 and p=0.650 for TSS and DFS, respectively). This result was verified by Kaplan-Meier survival analyses after propensity score matching (p=0.234 and p=0.765 for TSS and DFS, respectively). Conclusion LVSI does not significantly compromise the survival outcome of Chinese EEC patients.

Background: Epidemiological evidence revealed that stress is the causative factor of dyspeptic symptoms. It has been documented that duodenal inflammation is one of the key mechanisms of dyspepsia, and macrophage is crucial for inflammation. Aims: To determine whether patients with functional dyspepsia (FD) comorbid psychological stress have duodenal inflammation. Furthermore, to identify whether macrophage is involved in the mechanisms of stress-related duodenal inflammation by using water avoidance stress (WAS)animal model. Methods: Duodenal inflammation was observed and compared between FD patients with psychological factors and asymptomatic healthy controls. WAS mouse model with 1 h stress daily for 10 days was used to evaluate the duodenal inflammation at different time points to describe its dynamic changes. The role of macrophage in the development of duodenal inflammation was determined in an interventional study, in which the resident macrophages were depleted by clodronate liposomes. In both clinical and animal studies, the severity of duodenal inflammation was assessed by HE staining and immunocyte counts, the macrophage infiltration was detected by immunohistochemistry, and the expression of inflammatory cytokines was detected by real-time PCR. Results: FD patients with psychological factors developed severe duodenal inflammation in comparison with the healthy controls (immunocytes/HPF: 138.91±7.13 vs. 81.44±23.60, P<0.000 1). At the same time, the expressions of proinflammatory cytokines (IL-1β, TNF-α, and IL-17A) were increased, while the expressions of anti-inflammatory cytokines (IL-10 and TGF-β) were decreased (all P<0.05). In WAS mouse model, a dynamic change in duodenal inflammation which peaked on day 5 was observed, and the changes of macrophage infiltrating in the duodenal tissue were consistent with the duodenal inflammation. Clodronate liposomes pretreatment could effectively deplete macrophages, protected the WAS mouse model against duodenal inflammation (immunocytes/HPF: 75.10±4.08 vs. 202.43±5.18, P<0.001), with a marked reduction of the expressions of proinflammatory cytokines (IL-1β, TNF-α, and IL-8), and a marked elevation of the expression of anti-inflammatory cytokine IL-10 (all P<0.05). Conclusions: Psychological stress may lead to dyspeptic symptoms via macrophage-mediated duodenal inflammation.
