This paper highlights the specific nursing experiences in an early inflammatory bowel obstruction of a patient after the surgery for abdominal cocoon syndrome.Immediately after the surgery,the nursing care focused on prevention of postoperative metabolic disorders,including dynamic monitoring and correction of refeeding syndrome and goal-oriented sequential nutritional support management.Over the period of postoperative recovery,the nursing care shifted to prevention and treatment of early postoperative inflammatory bowel obstruction,including dynamic monitoring and identification of an early postoperative inflammatory bowel obstruction,goal-oriented early postoperative inflammatory small bowel obstruction(EPISBO)fluid therapy together with the traditional Chinese medicine to promote bowel movement and control inflammation,the auricle copper-blade Gua Sha combined with auricular point sticker compression to regulate qi and reduce bowel flatulence,as well as a goal-oriented early mobilisation to prevent a re-obstruction of bowel.The patient discharged at 28 days after surgery without an event.At the 6 months of postoperative follow-up,the patient was found in continuous improvement of relevant indicators and increase of body weight.

BACKGROUND:A novel aggregation induced luminescence fluorescence probe based on the mechanism of intramolecular motility restriction can be used for the detection of disease markers,tumor diagnosis,and bacterial imaging recognition.OBJECTIVE:To prepare a near-infrared Ⅱ nanoprobe called FA-DSPE-PEG-AIE@NPs based on aggregation-induced luminescence,and to explore its potential of targeted fluorescence imaging and photothermal therapy for prostate cancer.METHODS:Lecithin,polyethylene glycol phospholipids,folate polyethylene glycol phospholipids,and aggregation induced luminescent molecule 2TT-oC26B were used as raw materials.The folate-targeted nanoprobe FA-DSPE-PEG-AIE@NPs were prepared by nanoprecipitation method,and basic characterization of the nanoprobe was detected.PC3 human prostate cancer cells and human umbilical vein endothelial cells were selected as experimental objects.The cytotoxicity and phototoxicity of FA-DSPE-PEG-AIE@NPs were detected.PC3 human prostate cancer cells were selected as the experimental objects.Flow cytometry and calcein/propidium iodide staining were used to assess the efficacy of photothermal therapy.PC3 human prostate cancer cells were injected subcutaneously into the abdomen of BALB/C nude mice to establish a tumor model,and nanoprobes FA-DSPE-PEG-AIE@NPs were injected into the tail vein.The mice were immediately subjected to near-infraced Ⅱ fluorescence imaging.12 hours later,the tumor was irradiated by laser for 5 minutes,and the photothermal treatment effect was observed within 14 days.RESULTS AND CONCLUSION:(1)The nanoprobes FA-DSPE-PEG-AIE@NPs with a mean diameter of(171.0±0.3)nm showed a well-defined spherical morphology.The nanoprobe had a wide absorption spectrum and tail emission extending to the near-infrared Ⅱ which emitted a bright near-infrared Ⅱ fluorescence signal under laser irradiation.(2)The nanoprobes FA-DSPE-PEG-AIE@NPs had low cytotoxicity and high phototoxicity.The results of flow cytometry and calcein/propidium iodide staining showed that nanoprobes FA-DSPE-PEG-AIE@NPs had an obvious photothermal killing effect on human prostate cancer cells.(3)The nanoprobes FA-DSPE-PEG-AIE@NPs successfully achieved near-infrared Ⅱ fluorescence imaging of mouse blood vessels and the maximum enrichment time of the tumor was 12 hours.The vessel widths of the hind leg and single blood vessels of abdomen were estimated to be 0.63 mm and 0.42 mm.The tumor volume of mice was significantly smaller after 14 days of treatment.(4)The results show that nanoprobes FA-DSPE-PEG-AIE@NPs can achieve near-infrared Ⅱ fluorescence imaging and photothermal therapy of prostate cancer effectively,which may provide a new method for early diagnosis and combined treatment of prostate cancer.

Objective:To apply the Timed Up and Go Test(TUGT)to investigate the correlation between motor function, emotional state, cognitive function, and sleep quality among elderly individuals in the Chinese community.Methods:A cross-sectional study was conducted, involving 739 subjects aged 60 to 90 years, who were randomly recruited from December 2021 to August 2023 across Beijing, Tianjin, Zhejiang, Guangdong, and Hainan Provinces in China.Basic demographic information was collected, and the TUGT was utilized to assess motor function.Based on the TUGT time(t), the subjects were divided into three groups: normal motor function group, mild motor abnormality group, and significant motor abnormality group.Cognitive function was evaluated using the Chinese Revised Mini-Mental State Examination(MMSE), while the Patient Health Questionnaire Depression Scale(PHQ-9)was employed to measure the degree of depression.Additionally, the Epworth Sleepiness Scale(ESS)was used to assess excessive daytime sleepiness.The correlation between subjects' motor function and their cognitive abilities, mood, and sleep was subsequently analyzed.Results:Systolic blood pressure, heart rate, PHQ-9, MMSE, and ESS scores were identified as significant factors influencing TUGT time.Specifically, TUGT time was positively correlated with PHQ-9 and ESS scores, while exhibiting negative correlations with systolic blood pressure, heart rate, and MMSE scores.Additionally, TUGT time was negatively correlated with the MMSE subcomponents of orientation, immediate memory, and verbal ability.All observed differences were statistically significant(all P<0.05).Logistic regression analysis indicated that an increase in the PHQ-9 score was associated with an odds ratio( OR)of 1.099(95% CI: 1.045-1.155, P<0.001)(mild motor abnormality group)and 1.150(95% CI: 1.066-1.242, P<0.001)(Significant motor abnormality group).Additionally, a reduction in the MMSE score was observed, with an OR of 0.939(95% CI: 0.886-0.995, P<0.001)(mild motor abnormality group)and 0.793(95% CI: 0.729-0.862, P<0.001)(Significant motor abnormality group).Furthermore, an increase in the ESS score was noted, with ORs of 1.139(95% CI: 1.094-1.186, P<0.001)(mild motor abnormality group)and 1.203(95% CI: 1.132-1.279, P<0.001)(Significant motor abnormality group).These findings suggest that these variables are independently related to decreased motor function. Conclusions:Depression, cognitive impairment, and excessive daytime sleepiness are independent risk factors for motor dysfunction among elderly individuals in community settings.The Timed Up and Go Test TUGT can be utilized for the early screening of motor function decline in this population.

Ulcerative colitis （UC） is a chronic inflammatory bowel disease with complex etiology. The pathogenesis of this disease， due to a combination of factors， is complex and has not yet been elucidated. Among them， intestinal mucosal barrier damage is the basic pathological change of UC. As a non-destructive response of cells， autophagy regulates intestinal mucosal immunity， inflammation， oxidative stress， and bacterial homeostasis through degradation and reabsorption to actively repair damaged intestinal mucosal barrier， exerting a key role in the occurrence and development of UC. The disease is mainly treated clinically with aminosalicylic acid preparations， glucocorticoids， and immunosuppressants. Western medicine treatment of the disease has a fast onset of effect， and the short-term efficacy is definite， but the long-term application is easy to be accompanied by more adverse reactions. Moreover， some drugs are expensive， bringing great physical and mental pain and economic burden to patients. Therefore， it is urgent to explore new therapies with stable efficacy and mild adverse effects. In recent years， a large number of studies have shown that Chinese medicine can regulate autophagy of the intestinal mucosa with multiple targets and effects and repair the intestinal mucosal barrier function， thereby inhibiting the development of UC. Many experiments have shown that the active ingredient or monomers and compound formulas of Chinese medicine can improve the immunity of the intestinal mucosa， inflammation， oxidative stress， and flora by regulating the level of autophagy to maintain the normal function of the intestinal mucosal barrier to effectively intervene in UC， providing a new measure for the prevention and treatment of UC. However， there is a lack of systematic review of Chinese medicine in regulating the level of autophagy in the intestinal mucosa for the prevention and treatment of UC. Therefore， based on the current research on UC， autophagy process， and Chinese medicine treatment， this article reviewed the relationship of autophagy and its key target proteins with UC to clarify the key role of autophagy in UC production and systematically summarized Chinese medicines targeting the regulation of autophagy to treat UC in recent years to provide new ideas for the treatment and drug development of UC.

Ulcerative colitis （UC） is a chronic， non-specific inflammatory bowel disease. The pathogenesis of this disease is complex and is attributed to multiple factors. Intestinal mucosal barrier damage is the basic pathological change of UC， and intestinal flora disorder is one of the important characteristics of UC. Intestinal flora plays a key role in the pathological process of UC by regulating intestinal mucosal immunity and inflammatory response to repair the damaged intestinal mucosal barrier. At present， western medicine has the advantages of rapid action onset and significant short-term efficacy， but the curative effect of long-term use is not good， accompanied by many adverse reactions， causing great physical and mental pain to patients. Therefore， it is urgent to explore new treatment methods with definite long-term efficacy and mild adverse reactions. A large number of studies have shown that Chinese medicine can regulate intestinal flora through multiple targets in an all-around way， restore the homeostasis of the flora， and repair the damaged intestinal mucosal barrier， thereby inhibiting the progression of UC. Numerous studies have shown that the active components， monomers， and compounds of Chinese medicine can effectively antagonize UC by regulating the intestinal flora to improve the intestinal mucosal immunity， reduce the inflammatory response of the intestinal mucosa， and restore the normal physiological function of the intestinal mucosal barrier， providing a new strategy for UC prevention and treatment. Although there are some studies of the regulation of intestinal flora by Chinese medicine to prevent and treat UC， those studies have the shortcomings of systematic and comprehensive inadequacy. Therefore， based on the research status of UC， intestinal flora， and Chinese medicine treatment， this study reviewed the relationship between intestinal flora and UC and clarified the key role of intestinal flora in the occurrence and development of UC. At the same time， this paper comprehensively summarized the Chinese medicine that targeted the regulation of intestinal flora for the treatment of UC in the past five years to provide new strategies and ideas for UC treatment.

BACKGROUND:Gold nanoparticles are of great significance in the development of multifunctional transdermal drug delivery systems.Smaller gold nanoparticles can penetrate the dermis through the intercellular pathway,but are limited to their easy agglomeration and colloidal morphology,which makes it difficult to exert effects on low delivery efficiency. OBJECTIVE:To develop an ultrasound-optimized hydrogel delivery system by combining phase change nanodroplets with bio-adhesive hydrogel for percutaneous delivery of gold nanoparticles. METHODS:The ultrasound-responsive nanodroplets loaded with gold nanoparticles were prepared by the emulsion solvent evaporation method and loaded into the polydopamine-modified methylacryloyl gelatin hydrogel to prepare a composite hydrogel scaffold.The structure and chemical composition of the ultrasound-responsive nanogold carrier were characterized.The microstructure,porosity,permeability,rheology,in vitro hemostasis,and antibacterial properties of the composite hydrogel were characterized.The cell compatibility of the hydrogel scaffold was evaluated by live/dead staining,and the optimization effects of low-intensity pulsed ultrasound on the permeability,porosity,and mechanical properties of hydrogel were evaluated. RESULTS AND CONCLUSION:(1)Transmission electron microscopy and ultraviolet-visible spectroscopy proved the successful construction of nanogold carriers.The particle size and potential results demonstrated that the synthesized nanoscaled ultrasonic responsive carrier had good stability.(2)Live/dead cell staining proved that the prepared composite hydrogel scaffold had certain biocompatibility.(3)Scanning electron microscopy exhibited that the prepared composite hydrogel scaffold had a porous network structure,and numerous pores of about 2 μm appeared inside the macropores after the addition of nanodroplets and ultrasonic irradiation.The permeability experiment displayed that low-intensity pulsed ultrasound could optimize the porosity and permeability of hydrogel materials.The hemostatic performance of the composite hydrogel scaffold was better than that of the hemostatic sponge and polydopamine@methylacrylylated gelatin hydrogel scaffold.Under the irradiation of low-intensity pulsed ultrasound,the composite hydrogel scaffolds had good antioxidant effects and antibacterial properties.(4)Thermal imaging results manifested that gold nanoparticles were encapsulated in ultrasound-responsive nanobubbles,and more uniform dispersion could be obtained under ultrasonic excitation.(5)The results of the mechanical property test demonstrated that the storage modulus of the hydrogel increased before and after loading gold nanoparticles-nanodroplets,which showed stronger mechanical properties.The elongation at break was 122%,and the ductility was better than that without gold nanoparticles-nanodroplets(P<0.05).(6)These findings indicate that the composite hydrogel scaffold has good biocompatibility,antibacterial property,oxidation resistance,and hemostatic effect.

Objective To explore the application value of stage rehabilitation intervention under the Health action process approach(HAPA)model(SRI-HAPAM)combined with tranexamic acid(TXA)in elderly patients with femoral neck fracture(FNF)undergoing total hip arthroplasty(THA).Methods Elderly FNF patients with unilateral THA in the First Affiliated Hospital of Wenzhou Medical University from December 2022 to June 2023 were enrolled.According to the random number table method,the patients were divided into routine nursing(RN)group and TXA+SRI-HAPAM group.The RN group received conventional treatment after surgery,and the TXA+SRI-HAPAM group received TXA combined with SRI-HAPAM after surgery.The bleeding indexes[hidden blood loss(HBL),explicit blood loss(EBL)and blood transfusion volume(BTV)],and the levels of hemoglobin(Hb),C-reactive protein(CRP)and D-dimer(DD)were compared between the two groups at 24 h after surgery.The hip function[joint deformity(JD),joint function(JF),joint pain(JP),joint motion(JM)and total hip function(THF)],anxiety and depression[self-rating anxiety scale and self-rating depression scale],satisfaction with care,and complications were compared between the two groups at 3 months after surgery.Results A total of 100 elderly patients with unilateral THA due to FNF were included in the study,including 54 in the TXA+SRI-HAPAM group and 46 in the RN group.Before operation,there was no significant difference in Hb,CRP,DD,JD,JF,JP,JM,THF and SAS between the two groups(P>0.05).At 24 hours after operation,Hb decreased in the two groups,while CRP and DD increased(P<0.05),and the decrease in Hb and the increase in CRP and DD,as well as HBL,EBL and BTV in the TXA+SRI-HAPAM group,were lower than those in the RN group(P<0.05).At 3 months after operation,JD,JF,JP,JM and THF in both groups increased compared with those before operation,while SAS and SDS decreased compared with those before operation(P<0.05),and the functional scores of JD,JF,JP,JM and THF in the TXA+SRI-HAPAM group were significantly higher than those in the RN group,and the scores of SAS and SDS were lower than those in the RN group(P<0.05).3 months after surgery,the nursing satisfaction of the TXA+SRI-HAPAM group was significantly higher than that of the RN group,and the total complication rate was lower than that of the RN group(P<0.05).Conclusion Compared the Routine nursing,TXA combined with SRI-HAPAM more effectively promotes postoperative recovery in patients with THA.
