Objective To observe the effect of Shenfu injection on lung injury caused by hemor-rhagic shock(HS)in rats and explore the related potential mechanism.Methods Thirty-six SPF healthy male SD rats,aged 16-17 weeks,weighing 400-600 g,were randomly divided into three groups:sham op-eration group(group SH),HS group(group HS),and Shenfu injection group(group SF),12 rats in each group.In group SH,only the right femoral vein and femoral artery were separated after anesthesia,and ve-nous catheterization was not performed.HS model was established in groups SF and HS.In group HS,liquid resuscitation was performed through an intravenous catheter,and the resuscitation fluid consisted of the auto-blood lost and the compound sodium chloride injection equivalent to 1.5 times the blood loss and 10 ml/kg normal saline.In group SF,the resuscitation fluid consisted of the lost autoblood and the compound sodium chloride injection equivalent to 1.5 times the blood loss and Shenfu injection 10 ml/kg.The whole perfusion time was about 60 minutes.Six rats in the three groups were randomly anesthetized 24 and 48 hours after op-eration.The wet/dry weight ratio(W/D)of lung tissues was detected.The concentrations of interleukin-6(IL-6),IL-17,IL-10,and transforming growth factor-β(TGF-β)were detected by ELISA,the mRNA ex-pression of retinoic acid-related orphan nuclear receptor γt(RORγt),transcription factor forkhead box pro-tein 3(Foxp3),and hypoxia-inducible factor-1α(HIF-1α)in lung tissues were detected by PCR.The pro-tein contents of RORγt,Foxp3,HIF-1α,aquaporin 1(AQP1),and AQP5 in lung tissue were detected by Western blot.Pathological changesunder HE staining light microscope and lung injury scores were observed.Results Compared with 24 hours after operation,W/D,the concentrations of IL-6 and IL-17,mRNA ex-pression and protein content of RORγt and HIF-1α,and lung injury score were significantly decreased(P＜0.05),the concentrations of IL-10,and TGF-β,Foxp3 mRNA expression and protein content,and AQP1 protein content were significantly increased in group SF 48 hours after operation(P＜0.05).Compared with group SH,W/D,the concentrations of IL-6,IL-17,IL-10,and TGF-β,mRNA expression and protein content of RORγt,Foxp 3,and HIF-1α,and lung injury score were significantly increased(P＜0.05),AQP1 and AQP5 protein contents were significantly decreased in groups HS and SF 24 and 48 hours after operation(P＜0.05),and alveolar structure was damaged under light microscope and alveolar interstitium was filled with a large amount of edematous fluid,during which a large number of inflammatory cells infiltra-ted.Compared with group HS,W/D,the concentrations of IL-6 and IL-17,mRNA expression and protein content of RORγt and HIF-1α,and lung injury score were significantly decreased(P＜0.05),the concen-trations of IL-10 and TGF-β,Foxp3 mRNA expression and protein content,AQP1 and AQP5 protein con-tents were significantly increased in group SF 24 and 48 hours after surgery(P＜0.05),and the alveolar structure was improved under light microscope,and edema was reduced,and the number of inflammatory cells was reduced.Conclusion Shenfu injection can regulate the balance between pro-inflammatory factors IL-6 and IL-17,and anti-inflammatory factors IL-10 and TGF-β,increase the protein content of AQP1 and AQP5 in lung tissue,and decrease the W/D and injury score in lung tissue,thus alleviating lung injury in HS rats.The mechanism may be related to the regulation of HIF-1α-RORγt/Foxp3 balance.

Objective:To explore the changes in biological characteristics of adipose-derived stem cells (ASCs) in obese patients post successful weight loss, so as to provide a reference for the clinical application of these ASCs in refractory wound repair.Methods:This study was an experimental study. Twelve obese patients (8 females and 4 males, aged (50±9) years) who underwent abdominal skin tightening surgery after successful weight loss and were admitted to the First Affiliated Hospital of Zhengzhou University from April 2021 to April 2023 were included in weight loss group, and 12 healthy volunteers (10 females and 2 males, aged (50±9) years) who underwent abdominal liposuction and facial fat grafting surgery during the same period in the same institution were included in healthy group. Adipose tissue was collected from patients in weight loss group and volunteers in healthy group, and ASCs were extracted. Experiments were conducted using ASCs at passages 4 and 5. Cell proliferation levels were assessed using the methyl thiazolyl tetrazolium assay at 0 (immediately), 24, 48, and 72 hours of culture. The cell scratch test was performed and the cell migration rates at 12 and 24 hours after scratching were calculated. The cell Transwell assay was performed and the number of migration cells at 24 hours after culture was counted. Adipogenic and osteogenic induction assays were carried out, and the adipogenic and osteogenic differentiation levels of cells were detected after 18 and 21 days of induction, respectively. Real-time fluorescence quantitative reverse transcription polymerase chain reaction was employed to measure the mRNA expressions of lipoprotein lipase (LPL), peroxisome proliferator-activated receptor gamma (PPARγ), Runt-related transcription factor 2 (Runx2), osteopontin, alkaline phosphatase (ALP), matrix metalloproteinase 9 (MMP-9), and transforming growth factor beta (TGF-β). The sample number of each experiment was 12.Results:At 0 hour of culture, the cell proliferation levels of patients in weight loss group and volunteers in healthy group were 1.022±0.056 and 1.000±0.144, respectively, with no statistically significant difference between the groups ( P>0.05). At 24, 48, and 72 hours of culture, the cell proliferation levels of patients in weight loss group were 1.366±0.030, 1.353±0.012, and 1.390±0.016, respectively, which were significantly lower than 1.755±0.077, 1.737±0.014, and 1.700±0.023 of volunteers in healthy group (with t values of 16.27, 71.35, and 38.56, respectively, P values all <0.05). In the cell scratch test, at 12 and 24 hours after scratching, the cell migration rates of patients in weight loss group were lower than those of volunteers in healthy group, but the differences were not statistically significant ( P>0.05). In the cell Transwell assay, after 24 hours of culture, there was no statistically significant difference in the number of migrated cells between patients in weight loss group and volunteers in healthy group ( P>0.05). After 18 days of adipogenic induction, the cell adipogenic differentiation level of patients in weight loss group was significantly lower than that of volunteers in healthy group ( t=27.81, P<0.05). After 21 days of osteogenic induction, the cell osteogenic differentiation level of patients in weight loss group was significantly lower than that of volunteers in healthy group ( t=14.85, P<0.05). Compared with those of volunteers in healthy group, the mRNA expressions of LPL, PPARγ, TGF-β, and Runx2 of patients in weight loss group were significantly reduced (with t values of 59.48, 146.10, 46.10, and 3.13, respectively, P<0.05), while there were no statistically significant changes in the mRNA expressions of osteopontin, ALP, or MMP-9 ( P>0.05). Conclusions:Compared with healthy volunteers, the proliferative capacity of ASCs in obese patients after successful weight loss is significantly diminished, the differentiation potential is relatively weak, and the expression levels of some genes corresponding to adipogenic and osteogenic differentiation are decreased, which may affect the therapeutic efficacy of these ASCs in treating refractory wounds caused by burns, diabetes, or radiation injuries. Therefore, the donor differences of ASCs need to be considered in clinical application.

Objective:To retrieve the evidence on rehabilitation functional exercise for total knee arthroplasty (TKA) patients both domestically and internationally, and summarize the best evidence to provide a basis for constructing a management plan of rehabilitation functional exercise for TKA patients.Methods:Using population, intervention, professional, outcome, setting and type of evidence (PIPOST) to construct evidence-based nursing issues, all evidence on rehabilitation functional exercise for TKA patients was searched through computers in the Joanna Briggs Institute (JBI) Evidence-Based Health Care Center in Australia, British Medical Journal (BMJ) Best Practice, Embase, UpToDate, Web of Science, Cochrane Library, PubMed, American College of Sports Medicine, National Institute for Health and Clinical Excellence, China National Knowledge Infrastructure, WanFang Data and China Biomedical Literature Database. The Chinese and English search terms were "knee replacement/knee arthroplasty" and "functional training/exercise/strength training/early mobilization/recovery/ rehabilitation". The types of literature included guidelines, systematic reviews, summary of evidence, expert consensus, clinical decision-making, and randomized controlled trials (RCTs) . The search period was from the establishment of the database to January 10, 2023. Two researchers trained in evidence-based nursing independently completed the literature quality evaluation, and combined with professional judgment, extracted and summarized evidence for literature that met quality standards.Results:A total of 11 articles were included, including 4 guidelines, 4 systematic reviews, 2 RCTs, and 1 clinical decision-making. A total of 26 best evidence pieces were summarized from 5 aspects, namely multidisciplinary organizational management, pre-rehabilitation exercise, rehabilitation functional exercise plan, continuous function exercise, and exercise compliance.Conclusions:The best evidence summarized regarding rehabilitation functional exercise for TKA patients can provide a basis for medical and nursing staff to develop management plans. Medical and nursing staff need to consider clinical practice, patient's own condition, and willingness when applying evidence, and develop targeted rehabilitation functional exercise plans.

The aims of this research were to isolate a Aspergillus niger strain with higher beta-glucosidase activity. We utilized the beta-glucosidase producing strain Aspergillus niger CGMCC 3.316 as the original strain to first obtain a mutant 3-3M through ultraviolet irradiation. Then we studied the conditions of protoplast release and regeneration for strain 3-3M. We treated the protoplasts of strain 3-3M via ultraviolet irradiation and obtained another isolated mutant 60B-3D. The strain 60B-3D showed much higher beta-glucosidase production than the original strain and 3-3M strain. The beta-glucosidase activity of strain 60B-3D was 23.4 IU/mL, with an improvement of 39% compared with the original strain, and 23% compared with strain 3-3M. We also studied the fermentation process of strain 60B-3D, and compared it with the original strain and strain 3-3M. We found the strain 60B-3D exhibited an improvement in xylanase production. The comparison results also showed that the strain 60B-3D secreted more protein. These results were beneficial for producing beta-glucosidase through this productive mutant.
