OBJECTIVE To analyze the impact of the diagnosis-related groups （DRG） payment reform on the length of stay and medical costs in patients with chronic obstructive pulmonary disease （COPD） in Kashgar region， aiming to provide localized empirical evidence for the optimization of regional medical insurance payment methods. METHODS Based on the inpatient settlement database of the Xinjiang Uygur Autonomous Region Healthcare Security Administration， settlement data of COPD inpatients from 17 medical institutions in Kashgar region between January 1， 2022， and December 31， 2024， were extracted. The overall changes in patients’ length of stay and costs were compared before and after the reform. Subsequently， interrupted time series analysis （ITSA） was employed to explore the impact of the DRG payment reform on these variables. RESULTS Following the reform， both the average length of stay and various cost decreased significantly compared to the pre-reform period （ P ＜0.001）. At the overall sample level， the average length of stay， average total cost， average drug cost， average medical service cost， and average examination cost per admission all demonstrated significant long-term downward trends after the reform （ P ＜0.05）. However， the decrease in average out-of-pocket costs and the increase in average consumable costs per admission were not statistically significant （ P ＞0.05）. In tertiary medical institutions， the average length of stay and all categories of costs （except average consumable costs per admission） exhibited significant long-term upward trends after the reform （ P ＜0.05）； conversely， in secondary and lower-level medical institutions， the average length of stay， average total cost， average drug cost， average medical service cost， and average examination cost per admission showed significant long-term downward trends （ P ＜0.05）. CONCLUSIONS The DRG payment reform has achieved an overall effect of reducing the length of stay and controlling costs in COPD patients from Kashgar region. However， the effects vary across different levels of medical institutions： secondary and lower-level institutions show a long-term downward trend in length of stay and costs， whereas tertiary institutions exhibit a long-term upward trend. Furthermore， patients’ out-of-pocket financial burden does not show significant improvement.

Fritillariae Cirrhosae Bulbus is the dried bulb of perennial herbaceous plants in the Fritillaria genus(Liliaceae family) and is a representative traditional Chinese medicinal material with distinctive regional characteristics. Clinically, it is widely used in the treatment of dry cough, bronchial asthma, and other respiratory diseases, possessing significant medicinal and economic value and being highly esteemed in TCM. Currently, Fritillariae Cirrhosae Bulbus primarily relies on wild harvesting. However, due to excessive collection, its wild resources have drastically declined, and all source species have been classified as category Ⅱ in the List of National Key Protected Wild Plants, exacerbating the supply-demand imbalance in the market. To mitigate this issue, large-scale cultivation through the domestication of wild Fritillariae Cirrhosae Bulbus has become an inevitable trend. However, its strict environmental requirements, low propagation efficiency, high seedling mortality, and immature cultivation techniques have severely hindered industrialization. This study investigates the domestication process of Fritillariae Cirrhosae Bulbus, focusing on seed propagation, seedling cultivation, and medicinal material production. It also reviews the species and distribution of wild resources, their endangered status, market supply-demand dynamics, and the historical and current development of domestication. The findings indicate that enhancing propagation efficiency, optimizing cultivation models, and distinguishing between seed propagation and medicinal material production are key measures to accelerate the industrialization of domesticated Fritillariae Cirrhosae Bulbus. This research aims to promote the industrialization of Fritillariae Cirrhosae Bulbus domestication and provide a reference model for the conservation and sustainable utilization of rare and endangered medicinal plant resources.

The three-dimensional (3D) printed bone tissue repair guide scaffold is considered a promising method for treating bone defect repair. In this experiment, chitosan (CS), sodium alginate (SA), and mineralized collagen (MC) were combined and 3D printed to form scaffolds. The experimental results showed that the printability of the scaffold was improved with the increase of chitosan concentration. Infrared spectroscopy analysis confirmed that the scaffold formed a cross-linked network through electrostatic interaction between chitosan and sodium alginate under acidic conditions, and X-ray diffraction results showed the presence of characteristic peaks of hydroxyapatite, indicating the incorporation of mineralized collagen into the scaffold system. In the in vitro collagen release experiments, a weakly alkaline environment was found to accelerate the release rate of collagen, and the release amount increased significantly with a lower concentration of chitosan. Cell experiments showed that scaffolds loaded with mineralized collagen could significantly promote cell proliferation activity and alkaline phosphatase expression. The subcutaneous implantation experiment further verified the biocompatibility of the material, and the implantation of printed scaffolds did not cause significant inflammatory reactions. Histological analysis showed no abnormal pathological changes in the surrounding tissues. Therefore, incorporating mineralized collagen into sodium alginate/chitosan scaffolds is believed to be a new tissue engineering and regeneration strategy for achieving enhanced osteogenic differentiation through the slow release of collagen.

Objective To analyze the effects of irbesartan(IBN)regulating the stromal cell-derived factor-1(SDF-1)/CXC chemokine receptor 4(CXCR4)pathway on proliferation,migration,and radiosensitivity of lung cancer cells.Methods Human lung cancer A549 cells were randomly divided into the A549 group(without treatment),radiation group(4 Gy X-ray radiation),IBN group(1 μmol/L IBN treatment for 24 hours),IBN+radiation group(1 μmol/L IBN treatment for 24 hours+4 Gy X-ray radiation),pcDNA3.1 group(transfected with pcDNA3.1+1 μmol/L IBN treatment for 24 hours+4 Gy X-ray radiation),and SDF-1 group(transfected with pcDNA3.1 SDF-1+1 μmol/L IBN treatment for 24 hours+4 Gy X-ray radiation).The cell viability,colony formation,apoptosis,and migration of each group were observed.The leakage rate of lactate dehydrogenase(LDH)and Ang Ⅱ levels in cells were detected.Immunofluorescence method was applied to analyze the number of γH2AX focal points of cells in each group.Western blot was applied to detect the expression of proliferation and apoptosis related proteins and SDF-1/CXCR4 pathway related proteins.Results Both radiation and IBN treatment inhibited the proliferation and migration of A549 cells,promoted cell apoptosis,upregulated the number of γH2AX focal points and LDH leakage rate,upregulated the expression of Caspase-3,Bax,and Caspase-7,and downregulated the level of Ang Ⅱand expression of SDF-1,CXCR4,Bcl-2 and PCNA(P<0.05).The combined treatment of radiation and IBN further enhanced the changes of the above indicators(P<0.05).And SDF-1 treat-ment effectively reversed the effects of radiation and IBN treatment on the changes of the above indicators(P<0.05).Conclusion IBN can limit proliferation and migration of lung cancer cells,and increase radiosensitivity by inhibiting the SDF-1/CXCR4 pathway.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective:To investigate the clinical efficacy of 3D laparoscopic radical gastrec-tomy of gastric cancer.Methods:The prospective randomized controlled study was conducted. The clinical data of 90 patients undergoing total laparoscopic radical gastrectomy of gastric cancer in Zhangzhou Affiliated Hospital of Fujian Medical University from January to December 2022 were selected. Patients were randomly divided into the 3D laparoscopic group and the 2D laparoscopic group by the method of random number table. Patients underwent 3D or 2D laparoscopic radical gastrectomy of gastric cancer. Observation indicators: (1) grouping of enrolled patients; (2) intra-operative and postoperative situations; (3) feelings of the major surgeon during the operation. Com-parison of measurement data with normal distribution between groups was conducted using the independent sample t test. Comparison of count data between groups wsa conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data between groups was conducted using the nonparametric test. Results:(1) Group of enrolled patients. A total of 90 patients eligible for total laparoscopic radical gastrectomy of gastric cancer were selected. There were 56 males and 34 females, aged (61±7)years. All 90 patients were randomly divided into the 3D laparoscopic group and the 2D laparoscopic group, with 45 cases in each group. There was no significant difference in gender, age, body mass index, hypertension, diabetes mellitus, history of abdominal surgery, surgical method, tumor site and TNM staging between the two groups ( P>0.05), indicating comparability. (2) Intraoperative and postoperative situations. The operation time of the 3D laparoscopic group and the 2D laparoscopic group were (196±12)minutes and (204±14)minutes, respectively. The digestive tract reconstruction time of the 3D laparoscopic group and the 2D laparoscopic group were (81±8)minutes and (87±12)minutes, respectively. There were significant differences in operation time and digestive tract reconstruction time between the two groups ( t=-2.85, -2.43, P<0.05). After surgery, 3 cases of the 3D laparoscopic group experienced complications (1 case of abdominal infection, 2 cases of intestinal obstruction), and 8 cases of the 2D laparoscopic group experienced complications (2 cases of anastomotic leakage, 2 cases of abdominal infection, 4 cases of intestinal obstruction). There was no significant difference in postoperative complications between the two groups ( χ2=2.59, P>0.05). (3) Feelings of the major surgeon during the operation. After surgery, the major surgeon completed a questionnaire survey. The score of image quality perception of the 3D laparoscopic group and the 2D laparoscopic group were 4.73±0.08 and 4.46±0.09, respectively. The score of hand-eye coordination experience of the 3D laparoscopic group and the 2D laparoscopic group were 4.60±0.09 and 4.55±0.08, respectively. The score of operation comfort of the 3D laparoscopic group and the 2D laparoscopic group were 4.81±0.05 and 4.62±0.08, respectively. The score of eye comfort of the 3D laparoscopic group and the 2D laparoscopic group 4.49±0.07 and 4.68±0.07, respectively. There were significant differences in the above indicators between the two groups ( t=15.04, 2.57, 13.51, -12.88, P<0.05). Conclusions:Compared with 2D laparoscopy, 3D laparoscopic radical gastrec-tomy of gastric cancer has shorter operation time and digestive tract reconstruction time, does not increase postoperative complications, and has better feelings of the major surgeon in image quality perception, hand-eye coordination experience and operation comfort.
