A refractory Crohn's disease patient with recurrent perianal fistulas failed to overcome the secondary loss of response to infliximab(IFX)after therapeutic drug monitoring,intensified anti-TNF dosing and in combination with azathioprine.Throughout the treatment process,clinical pharmacists assisted physicians in analyzing the risk factors and causes for loss of response,providing evidence for an individualized treatment strategy,and monitoring the efficacy and safety of the treatment.According to the relevant guidelines and literature,ustekinumab was the preferred biological agent after anti-TNF failure in perianal fistulizing Crohn's disease(pfCD).At the 12-week follow-up,fecal calprotectin and C-reactive protein decreased markedly,and the patient achieved fistula healing.This case provides references for current management strategy and perspective in IFX secondary non-responders with refractory pfCD,especially those who have undergone optimization therapy.

Objective:To construct an indicator system for the development of nursing disciplines in ClassⅢ Grade A general hospitals.Methods:An initial draft of the indicator system was established through literature research and expert meetings. The Delphi method and purposive sampling were used from January to April 2023 to conduct two rounds of expert consultations with 17 nursing experts from four medical units nationwide and three nursing colleges. The indicators were revised and refined, resulting in the establishment of a nursing discipline construction indicator system for ClassⅢ Grade A general hospitals. The level of expert engagement was represented by the questionnaire recovery rate, expert authority by the expert authority coefficient ( Cr), and the degree of expert opinion coordination by Kendall 's harmony coefficient (Kendall 's W) . Results:The recovery rates for both rounds of expert consultation questionnaires were 100.00% (17/17), with expert Cr of 0.87. The CV values ranged from 0.049 to 0.260 and 0 to 0.140, respectively, while Kendall 's W were 0.221 and 0.257 ( P< 0.01). The final indicator system for the construction of nursing disciplines in ClassⅢ Grade A general hospitals included six primary indicators, 18 secondary indicators, and 63 tertiary indicators. Conclusions:The nursing discipline construction indicator system developed for ClassⅢ Grade A general hospitals in this study is scientific, reliable, and comprehensive. It can provide a reference for the construction of nursing disciplines in Class Ⅲ Grade A general hospitals.

AIM:To explore the correlation between trimethylamine-N-oxide(TMAO)and type 2 diabetic kidney disease(DKD),and to provide new ideas for the early clinical diagnosis of DKD.METHODS:A total 246 patients with type 2 diabetes mellitus(T2DM)ad-mitted to the Department of Endocrinology of the First Hospital of Lanzhou University from January 1,2020 to May 31,2020 were divided into diabetic kidney disease group(DKD group)and simple diabetes mellitus group(NDKD group).According to urinary albumin/creatinine ratio(UACR),the patients were divided into A1,A2 and A3 subgroups.According to the estimated glomerular filtration rate(eGFR),the patients were divided into G1,G2,G3 and G4-5 sub-groups.According to the Kidney Disease:Improving Global Outcomes(KDIGO)guidelines,the risk of progression of DKD was assessed(low,medium,high or very high risk).General clinical data and laboratory indicators were collected.TMAO level was measured by euzymelinked immunosorbent assay.SPSS 25.0 software was used for statistical analysis.RESULTS:In T2DM patients,TMAO level was positively correlated with UACR(r=0.515,P<0.01)and negatively correlated with eGFR(r=-0.409,P<0.01).TMAO is an indepen-dent risk factor for the onset and progression of DKD.In diagnostic model,the AUROC was 0.745 with op-timal cut-off value was 5.37μmol/L.CONCLUSION:TMAO is closely related to the occurrence and de-velopment of DKD,and it has certain clinical predictive value for DKD.Therefore,TMAO may become a po-tential target for the early diagnosis and treatment of DKD.

Objective To investigate changes of laboratory indicators and pathological features of Henoch-Schonlein purpura nephritis(HSPN)children after crescent formation,and to explore non-invasive biomarkers for predicting crescent formation.Methods A total of 278 children with HSPN who were hospitalized from January 2018 to July 2023 were selected and divided into the crescent formation group(196 cases)and the non crescent formation group(82 cases)based on their crescent formation status.Patients in the crescent formation group were sub-divided into the cellular crescent formation group(52 cases)and the cellular fibrous crescent formation group(144 cases)based on the type of crescent formation.Laboratory indicators and pathological characteristics were compared between different groups.The correlation between each indicator and the proportion of crescent formation was analyzed.The influencing factors of crescent formation were analyzed by Logistic regression.Receiver operating characteristic(ROC)curves were plotted,and the effectiveness of laboratory indicators in predicting crescent formation was evaluated.Results Compared with the non crescent formation group,24-hour urine protein quantification(24 hUP),urine immunoglobulin G/creatinine(UGCR),urine red blood cell count(URBC),neutrophil/lymphocyte ratio(NLR),blood urea nitrogen(BUN)and triglycerides(TG)were significantly increased in the crescent formation group.There were increased proportion of diffuse mesangial hyperplasia(Mb),renal tubular atrophy or interstitial fibrosis(T1)(P＜0.05).Compared with the cellular crescent group,the proportion of glomerular segmental sclerosis or adhesion(S1)and T1 were increased,and the proportion of crescent formation was higher in the cellular fibrous crescent group.The proportion of capillary endothelial cell proliferation(E1)was decreased in the cellular crescent group(P<0.05).Spearman correlation analysis showed that 24 hUP,UGCR,URBC,NLR,BUN,TG,Mb and T1 were positively correlated with the proportion of crescent formation(all P＜0.05).The results of multivariate Logistic regression analysis showed that elevated UGCR and T1 were risk factors for crescent formation.The area under the curve(AUC)predicted by UGCR for crescent formation was 0.731(95%CI:0.667-0.795,P＜0.05),with an optimal cutoff value of 5.00 mg/mmol,sensitivity of 0.744 and specificity of 0.610.Conclusion UGCR can be used as a non-invasive biomarker to assist in evaluating crescent formation in children with HSPN.

Objective To observe the value of MR lymphangiography(MRL)radiomics for evaluating central conducting lymphatic anomaly(CCLA).Methods Sixty-one patients with complex lymphatic anomaly,including 41 CCLA(group A),20 non-CCLA(generalized lymphatic anomaly and Gorham-Stout disease)and 20 subjects with normal thoracic duct(group B,n=38)were retrospectively enrolled.Cervical and thoracic(combined with abdominal if necessary)MRL was acquired using three-dimensional heavily T2W fast spin echo sequence.ROI was delineated along overall thoracic duct,and radiomics features were extracted.Data sets of group A and B were divided into K subsets using 5-fold cross-validation.The union of(K-1)subset was always used as training set,while the other subsets were used as validation set.Radiomics model was constructed based on support vector machine(SVM)algorithm.Receiver operating characteristic curve was drawn,the area under the curve(AUC)was calculated to evaluate the efficacy of SVM model for assessing CCLA.Results The proportions of bifurcation,cystoid change and extension of main thoracic duct,and extension of terminal thoracic duct in group A were all higher,while of normal main and terminal thoracic duct in group A were both lower than those in group B(all P＜0.05).No significant difference of proportions of multiple thoracic ducts,dextral thoracic duct,part of thoracic duct invisible,multiple terminal thoracic ducts,cystoid change of terminal thoracic duct nor terminal thoracic duct pampiniform was found between groups(all P＞0.05).The sensitivity,specificity,accuracy,positive predictive,negative predictive and AUC of SVM model for evaluating CCLA in training set was 78.95％,97.56％,88.61％,96.77％,83.33％and 0.920,respectively,which in validation set was 78.95％,83.57％,82.28％,83.33％,81.40％and 0.833,respectively.Conclusion MRL radiomics could be used to effectively evaluate CCLA.

ObjectiveTo observe the effect of enriched environment (EE) combined with acupuncture at head point (HA) on behavior in rats with autism spectrum disorder. MethodsHealthy female Wistar rats were given peritoneal injection of sodium valproate at 12.5 days of gestation. Twenty-four male offspring rats were randomly selected and then randomly divided into model group (n = 6), EE group (n = 6), HA group (n = 6) and EE combined with HA group (the combined group, n = 6). Six male offspring rats born from female mice injected with the same amount of saline intraperitoneally were as control group. After four weeks of treatment, all the five groups were tested with three-chamber test and marble burying test, and the sociability index, the social novelty index and the number of buried marbles were recorded. The levels of interleukin (IL)-1β and IL-6 in peripheral blood were determined by enzyme-linked immunosorbent assay (ELISA). ResultsAfter treatment, compared with the model group, the sociability index and the social novelty index improved (P < 0.05), the number of buried marbles reduced (P < 0.05), and the levels of IL-6 and IL-1β in peripheral blood decreased in EE group, HA group and the combined group (P < 0.05); while the combined group was the best (P < 0.01). ConclusionBoth EE or acupuncture at HA could improve behavioral symptoms, and reduce the expression of inflammatory factors in rats with autism spectrum disorder. The combination of the two methods showed the best result.

Major depressive disorder(MDD)is a common mental illness.Currently,nearly 16%of the global population is affected by depression-related symptoms,while the diagnosis and treatment rate of MDD patients in China is only 9.5%.MDD is characterised by high morbidity and low recovery rate,and how to effectively improve its therapeutic effect has been a hot research topic in recent years.Antidepressants,as the main treatment for MDD,have the disadvantages of many adverse effects and slow onset of action,prompting people to pay attention to the non-pharmacological treatments of MDD.Dietary intervention is a kind of non-pharmacological treatment by changing dietary structures and rhythms;the current application of dietary intervention to psychiatry is very extensive,and it has been proved to be effective in the treatment of depression.Recent research suggests that dietary interventions can treat and ameliorate depressive symptoms by influencing brain-gut axis-related eating mechanisms.This article reviews the multidimensional exploration of dietary interventions in the treatment of depression:dietary structure interventions,dietary rhythm interventions,and the role of intestinal flora.It details the modalities of dietary interventions and the related mechanisms involved,and provides reference for dietary interventions in the treatment of depression-related symptoms.

Objective:To investigate the prevalence and potential classification of symptoms after total knee arthroplasty (TKA) in patients with knee osteoarthritis (KOA), and to analyze the differences in demographic characteristics and surgical data, compare the different potential subgroups, in order to provide a basis for clinical symptom management plans.Methods:This study was a multicenter cross-sectional survey. Through convenience sampling, patients with KOA undergoing TKA in the orthopaedic wards of four tertiary hospitals in Urumqi were selected as the study from November 2023 to February 2024. The study subjects were surveyed using a general information questionnaire, the Visual Analogue Scale (VAS) for pain, the Hospital Anxiety and Depression Scale (HADS), and the Pitts Burgh Sleep Quality Index (PSQI), and the degree of postoperative joint swelling and size of ecchymosis were measured. Latent class analysis was performed using Mplus 8.3 software, and Logistic regression analysis was conducted using SPSS 26.0 software to explore the influencing factors of the latent classes.Results:Totally 337 effective questionnaires were collected, and the recovery rate was 94.7% (337/356), and the age distribution ranged from 47 to 85 (65.19 ± 6.99) years old, with 90 (26.7%) males and 247 (73.3%) females. There were 92.3% (311/337) of TKA patients with postoperative symptom cluster. The symptom cluster of patients with TKA were identified as 3 classes. They were named as "high level pain-psychological disorder group"(12.5%, 39/311), "high bruises-moderate psychological disorders group"(25.4%, 79/311) and "low symptom burden group" (62.1%, 193/311). The results of the unordered multi-class logistic regression analysis showed that age 45-59 years ( OR = 2.367), body mass index 24.0-27.9 kg/m 2 ( OR = 0.207), living with children/parents ( OR = 6.473), and this being the second joint surgery ( OR = 0.040) were the factors influencing the "high level pain-psychological disorders group" (all P<0.05). The factors influencing the "high bruises-moderate psychological disorders group" were living with children/parents ( OR = 4.023), comorbid chronic diseases ( OR = 1.979, 3.842), and intraoperative blood loss ≤100 ml ( OR = 2.342) (all P<0.05). Conclusions:The postoperative symptom cluster of TKA patients have a relatively high incidence, and there is heterogeneity within the symptom cluster, so nurses need to identify at-risk patients early according to the characteristics of different categories and give interventions.

Objective:To explore the prognostic effect and safety of neurally adjusted ventilatory assist (NAVA) mode on the patients with severe neurological cerebrovascular disease undergoing mechanical ventilation.Methods:A prospective study was conducted. Fifty-four patients with cerebrovascular disease undergoing mechanical ventilation admitted to the neurosurgery intensive care unit (NSICU) of the First Affiliated Hospital of Wannan Medical College (Yijishan Hospital) from December 2020 to May 2022 were enrolled. They were divided into NAVA group and pressure support ventilation (PSV) group by computer random number generator with 27 patients in each group. The ventilation time of the two groups was ≥72 hours. The general basic data of the two groups were recorded. The time without mechanical ventilation 28 days after enrollment, total length of mechanical ventilation, survival rate of 90 days after enrollment, length of NSICU stay, total length of hospital stay, NSICU mortality, in-hospital mortality, Glasgow outcome score (GOS), complications related to mechanical ventilation, and changes of respiratory mechanics indexes, arterial blood gases, vital signs, and diaphragm function indexes were observed.Results:The time without mechanical ventilation 28 days after enrollment in the NAVA group was significantly longer than that in the PSV group [days: 22 (15, 26) vs. 6 (0, 23), P < 0.05]. However, there were no significant differences in the total length of mechanical ventilation, 90-day survival rate, length of NSICU stay, total length of hospital stay, NSICU mortality, in-hospital mortality, GOS score, and incidence of mechanical ventilator-related complications between the two groups. In terms of respiratory mechanics parameters, the expiratory tidal volume (VTe) on 3 days after mechanical ventilation of patients in the NAVA group was significantly lower than that on 1 day and 2 days, and significantly lower than that in the PSV group [mL: 411.0 (385.2, 492.6) vs. 489.0 (451.8, 529.4), P < 0.01]. Minute ventilation (MV) at 2 days and 3 days in the NAVA group was significantly higher than that at 1 day, and significantly higher than that in the PSV group at 2 days [L/min: 9.8 (8.4, 10.9) vs. 7.8 (6.5, 9.8), P < 0.01], while there was no significant change of MV in the PSV group. At 1 day, peak airway pressure (Ppeak) and mean airway pressure (Pmean) in the NAVA group were significantly lower than those in the PSV group [Ppeak (cmH 2O, 1 cmH 2O≈0.098 kPa): 14.0 (12.2, 17.0) vs. 16.6 (15.0, 17.4), Pmean (cmH 2O): 7.0 (6.2, 7.9) vs. 8.0 (7.0, 8.2), both P < 0.05]. However, there was no significant difference in the Ppeak or Pmean at 2 days and 3 days between the two groups. In terms of arterial blood gas, there was no significant difference in pH value between the two groups, but with the extension of mechanical ventilation time, the pH value at 3 days of the two groups was significantly higher than that at 1 day. Arterial partial pressure of oxygen (PaO 2) at 1 day in the NAVA group was significantly lower than that in the PSV group [mmHg (1 mmHg≈0.133 kPa): 122.01±37.77 vs. 144.10±40.39, P < 0.05], but there was no significant difference in PaO 2 at 2 days and 3 days between the two groups. There was no significant difference in arterial partial pressure of carbon dioxide (PaCO 2) or oxygenation index (PaO 2/FiO 2) between the two groups. In terms of vital signs, the respiratory rate (RR) at 1, 2, and 3 days of the NAVA group was significantly higher than that of the PSV group [times/min: 19.2 (16.0, 25.2) vs. 15.0 (14.4, 17.0) at 1 day, 21.4 (16.4, 26.0) vs. 15.8 (14.0, 18.6) at 2 days, 20.6 (17.0, 23.0) vs. 16.7 (15.0, 19.0) at 3 days, all P < 0.01]. In terms of diaphragm function, end-inspiratory diaphragm thickness (DTei) at 3 days in the NAVA group was significantly higher than that in the PSV group [cm: 0.26 (0.22, 0.29) vs. 0.22 (0.19, 0.26), P < 0.05]. There was no significant difference in end-expiratory diaphragm thickness (DTee) between the two groups. The diaphragm thickening fraction (DTF) at 2 days and 3 days in the NAVA group was significantly higher than that in the PSV group [(35.18±12.09)% vs. (26.88±8.33)% at 2 days, (35.54±13.40)% vs. (24.39±9.16)% at 3 days, both P < 0.05]. Conclusions:NAVA mode can be applied in patients with neuro-severe cerebrovascular disease, which can prolong the time without mechanical ventilation support and make patients obtain better lung protective ventilation. At the same time, it has certain advantages in avoiding ventilator-associated diaphragm dysfunction and improving diaphragm function.
