Objective To evaluate the effect of multi-disciplinary team(MDT)management mode on the preven-tion and control of carbapenem-resistant Enterobacterales(CRE)infection after lung transplant surgery,and explore the influencing factors for CRE infection after lung transplant.Methods A total of 654 lung transplant recipients from Lung Transplant Center of Wuxi People's Hospital from January 2014 to July 2023 were selected as the re-search subjects.According to the time nodes of the implementation of MDT management mode,lung transplant re-cipients from January 2014 to December 2019 were assigned to the control group without implementation of MDT management mode.Lung transplant recipients from January 2020 to July 2023 were in the intervention group with MDT management mode implementation.Kaplan-Meier method was used to calculate the risk of CRE infection in lung transplant recipients 90 days after surgery.Cox regression model was used to adjust variables such as length of hospital stay,surgical duration,and catheterization days of three catheters,and the effect of implementing MDT management mode on the risk of CRE infection was analyzed.Results Among 654 lung transplant recipients,215 had healthcare-associated infection(HAI),including 158 cases from the control group and 57 from the intervention group,with HAI rates of 38.54％and 23.36％,respectively.The incidence of HAI in lung transplant recipients in the intervention group was lower than that in the control group(x2=15.965,P＜0.001).A total of 74 cases of CRE infection were confirmed,and CRE infection rate in the intervention group was lower than that in the control group(7.79％[19/244]vs 13.41％[55/410];x2=4.828,P=0.028).By the end of the 90-day follow-up period,the cumulative infection risks of the control group and intervention group were 14.67％and 8.26％,respectively,with a statistically significant difference between the two groups(P＜0.05).The implementation of MDT manage-ment mode was a protective factor for post-operative CRE infection in lung transplant recipients,while duration of surgery,duration of ventilator use,and duration of urinary catheterization were risk factors for CRE infection(all P＜0.05).Conclusion Implementing MDT management mode in lung transplant recipients can effectively reduce the risk of post-operative CRE infection.Continuously standardizing and implementing MDT management of multidrug-resistant organisms in hospitals is an important mean of preventing CRE infection and controlling transmission.

Objective:To explore the effect of exercise on glycemic control and physical indicators among community-dwelling persons with type 2 diabetes mellitus (T2DM).Methods:A total of 42 T2DM patients undergoing regular follow-up at a community health center were divided into a control group and an exercise group. To minimize confounding factors, 1∶1 propensity score matching was performed, resulting in 21 patients in each group. Both groups received standardized diabetes management, including medication, dietary guidance and diabetes health education. The exercise group additionally performed exercises which integrated sports and medical care models. The experiment lasted 8 weeks. Before and after the intervention, glycosylated hemoglobin A1c (HbA1c) levels, body weight, body mass index (BMI), fat mass, visceral fat area (VFA), fat mass index (FMI) and appendicular skeletal muscle mass index (ASMI) were recorded and compared between the two groups. Moreover, the actual exercise compliance of the exercise group was observed, along with any adverse events such as hypoglycemia or exercise-related injuries, as well as changes in antidiabetic medication dosage.Results:After the intervention, significant improvement was observed in both groups in all of the measurements, but with the average HbA1c, BMI, fat mass, VFA and FMI values of the exercise group then significantly better than the control group′s averages. The average compliance rate in the exercise group was 60%. No cases of hypoglycemia or exercise-related injuries were reported during the intervention, and there were no changes in the use of anti-diabetes medications.Conclusions:Exercise effectively improves glycemic control and physical indicators among community-dwelling T2DM patients. However, exercise compliance needs improving.

Objective:To analyse the composition of Astragali Radix and its honey-processed products through a combination of UPLC-Q-TOF/MS and molecular network; To compare the changes in the main components of Astragali Radix before and after honey-frying.Methods:The aqueous extracts of Astragali Radix before and after honey-frying were prepared, and the compositions were detected by UPLC-Q-TOF/MS, analyzed and identified by the Global Natural Products Molecular Network Analysis Platform (GNPS). The generated molecular networks were visualized and analyzed using Cytoscape 3.9.1 software. The compounds were identified by Masslynx 4.2 software based on the secondary fragmentation information of the compounds, and the changes in the content of the components before and after the processing of Astragali Radix were analysed.Results:47 flavonoids and 34 triterpenoid saponins were presumably identified from Astragali Radix and its honey-frying products using the above analytical methods, with about 87% of the flavonoids and about 82% of the saponins decreasing in content after honey-frying.Conclusions:The compositional changes of Astragali Radix before and after honey-frying are rapidly resolved and visualised by liquid-quantity coupling combined with molecular network. It is found that some of the flavonoids and saponins components of Astragali Radix underwent hydrolysis after honey-frying and it may be the material change basis for processing efficiency enhancement.

AIM: To investigate the effects of isonlosinine on proliferation, invasion, migration and autophagy of PC9 cells in non-small cell lung cancer (NSCLC), and to explore its possible molecular mechanism. METHODS: The effect of Isoliensinine on the proliferation of PC9 cells were measured by CCK-8 assay, and the IC50 value of PC9 cells was calculated. Wound healing and transwell experiments were used to study the effect of Isoliensinine on migration and invasion of PC9 cells in vitro, respectively. The formation of autophagosome was observed with acridine orange staining under fluorescence microscope. The expression levels of LC3, pERK and ERK in the PC9 cells were determined by western blot. RESULTS: Isonlosinine significantly inhibited the proliferation of PC9 cells. IC50 of isonlosinine (24 h) for the PC9 cells was 34.11 µmol / L. Isonlosinine significantly inhibited cell migration and invasion of PC9 cells. The results of acridine orange fluorescent staining showed that the number of the intracellular acid dye follicular bright red fluorescence in PC9 cells was significantly increased after isonlosinine treatment, while the autophagic lysosomes were rarely observed in control group. The expression of LC3-II in PC9 cells was significantly enhanced after isonlosinine treatment. Furthermore, molecular mechanism study showed that isonlosinine could activate the expression level of p-ERK. CONCLUSION: Isoliensinine significantly inhibits the proliferation, migration and invasion, and induces autophagy of PC9 cells, which may be correlated with the activation of ERK signaling pathway.

Objective:To establish an in vitro culture system of small intestinal organoid in normal mice and perform functional identification, and to provide an in vitro research tool for material transport in the intestine under chronic kidney disease. Methods:The small intestinal crypts of C57BL/6J mice were isolated, extracted and cultured in an in vitro three dimension culture system. The formation of small intestinal organoid was observed with inverted microscope. The tissue structure of the small intestinal organoid was observed by hematoxylin and eosin staining. The cellular composition of the small intestinal organoid was identified by immunofluorescence. The expression of substance absorption-related transporters in the small intestinal organoid was detected by real time fluorescence quantitative PCR. Results:The small intestinal crypts were successfully extracted. The organoids of small intestine and different intestinal segments were successfully constructed. The cultured organoids had vigorous proliferation ability and maintained proliferation ability after passing through generations. Immunofluorescence results showed that the small intestinal organoids expressed mucin2, chromogranin A, oflm4 and lysozyme, which were different types of intestinal cell biomarkers. The PCR results showed that small intestinal organoids expressed calcium, phosphate and sodium absorption-related transporters, and the mRNA expression levels of major transporters for sodium and phosphate absorption in different intestinal segments-like organs were consistent with those in vivo, which was consistent with the characteristics of small intestinal segmental absorption. Conclusions:The successful construction of small intestine and different intestinal segments organoids, and the first observation of the expression of substance absorption-related transporters in such organoid, provide a stable and convenient in vitro research tool for the development of intestinal substance transport in chronic kidney disease.

Closed-loop hospital management can effectivly cope with the COVID-19 pandemic. In order to ensure the continuity of treatments for hemodialysis patients under closed-loop management and minimize possible medical and infection risks, Huashan Hospital affiliated to Fudan University and 9 hospitals in Shanghai established a hemodialysis alliance in January 2021.The alliance optimized hemodialysis resources within the region through overall planning by preparing sites, materials and personnel shifts in advance, and establishing management systems and work processes to ensure that patients could be quickly and orderly diverted to other blood dialysis centers for uninterrupted high-quality hemodialysis services, in case that some hemodialysis centers in the alliance under closed-loop management.From November 2021 to April 2022, 317 of 1 459 hemodialysis patients in the alliance were diverted to other centers for treatment, accumulating 1 215 times/cases of treatments without obvious adverse reactions. The practice could provide a reference for medical institutions to quickly establish mutual support mode under major public health events.

Objective:To explore the effects of dietary phosphate restriction education on serum phosphorus level, dietary phosphate intake and the knowledge of hyperphosphatemia in maintenance hemodialysis (MHD) patients.Methods:This study was a retrospective cohort study. A total of 116 hemodialysis patients in Huashan Hospital, Huadong Hospital and Tongji Hospital from October 2019 to December 2020 were enrolled in this study. They were divided into short-term group (84 cases) and long-term group (32 cases). The short-term group did not receive education or received education≤60 minutes. Meanwhile, the long-term group received education>60 minutes. Serum phosphorus level, dietary phosphate intake and knowledge of hyperphosphatemia were compared between the two groups after 4 weeks.Results:At baseline, age [64(56, 69) years old vs 65(60, 73) years old, Z=-1.493, P=0.136], the proportion of males [58.3%(49/84) vs 56.3%(18/32), χ2=0.041, P=0.839], dialysis age [55(26, 130) months vs 53(20, 132) months, Z=-0.062, P=0.951], body mass index, diabetes history, single-pool Kt/V, proportion of calctriol used, blood calcium, blood phosphorus, intact parathyroid hormone and dietary protein, dietary phosphorus and dietary phosphorus protein ratio had no statistical significance between short-term group and long-term group (all P>0.05). Adequate dietary phosphate restriction education reduced dietary phosphate intake [777.98(653.81, 943.16) mg/d vs 896.56(801.51, 1 015.51) mg/d, Z=-2.903, P=0.004], phosphate/protein ratio [13.16(11.52, 14.21) mg/g vs 15.27(13.31, 17.48) mg/g, Z=-3.929, P<0.001] and serum phosphorus level [(1.42±0.37) mmol/L vs (1.85±0.44) mmol/L, t=4.984, P<0.001]. Meanwhile, such education significantly improved achievement rate of serum phosphorus (62.5% vs 41.7%, χ2=4.034, P=0.045). In addition, patients in long-term group answered more questions correctly (completely correct plus partially correct) about the causes (93.8% vs 72.6%, χ2=6.120, P=0.013), poor prognosis (78.1% vs 52.4%, χ2=6.372, P=0.012) of hyperphosphatemia as well as the types of food with high phosphate (65.6% vs 52.4%, χ2=1.650, P=0.199). Conclusion:Adequate dietary phosphate restriction education reduces serum phosphorus level and dietary phosphate intake, and improves the knowledge of hyperphosphatemia in MHD patients.
