Objective To evaluate the clinical efficacy and safety of application of anterograde flexible ureteroscope in the treatment of ureterointestinal anastomotic strictures in patients after Bricker urinary diversion. Methods From March 2009 to July 2012, 6 patients with ureterointestinal anastomotic strictures after Bricker procedure were enrolled in this study. The average age of the patients was (61 ±7) years old. The first clinical presentation was averagely (6.3 ±2.5) months after the Bricker procedure. There were 4 cases with left side strictures and 2 cases with right side ones. The urinary tract ultrasound, CT, KUB+IVP and antegrade urography were carried out to identify the obstructive portion. The mean length of stricture was 0.9cm (0.4~2.5) . First, all patients underwent percutaneous nephrostomy (PCN), then inside incision by Holmium:YAG laser under anterograde flexible ureteroscopy and lithotripsy (with calculi) . The F6 double J ureteral stent was indwelled for 12 weeks. KUB+IVP was performed after removal of double J ureteral stents. Results The mean operative time was (53±8) min. The mean hospital stay was (5.5±2) days. The blood loss was 3~6 mL. The average follow-up was 18 months (6~30) . No recurrence was found in 5 patients. One case had recurrent stricture after the first procedure, which was successfully managed by the flexible ureteroscopy again and replacing double J ureteral stent every 12 months. Conclusion The inside incision by anterograde flexible ureteroscopic Holmium:YAG laser is safe and effective for ureterointestinal anastomotic strictures in patients after Bricker urinary diversion, with less complications.

Objective To evaluate the relationship between the perfusion mode of neovascularization of carotid plaque in CEUS and the ischemic stroke in transient ischemic attack (TIA) patient.Methods A total of 73 TIA patients according to the inclusive criteria were enrolled.All the patients underwent routine carotid ultrasonic examination.And 61 patients with plaque thicker than 2.5 mm in carotid bifurcation underwent CEUS and follow-up for at least 18 months.All the patients were divided into recurrent and non-recurrent groups.Logistic regression analysis were performed to detect the risk factors for incurrence of ischemic stroke or recurrence of TIA in 18 months.Results There were statistical differences between 2 groups in hypertension,diabetes,hyperlipemia,smoking history,family history of stroke,medication compliance,two-dimensional ultrasound and CEUS characteristics (all P＜0.05).Multivariate Logistic regression analysis showed that all the factors correlated with the recurrency,from big to small order were the CEUS characteristics of carotid plaque,hypertension,medication compliance,diabetes,two-dimensional ultrasound characteristics of carotid plaque.Conclusion CEUS could evaluate the perfusion mode of neovascularization in carotid plaques.For TIA patients,CEUS could predict the incurrence of ischemic stroke or recurrence of TIA,which can guide TIA patients targeted prophylaxis of them.

Objective To investigate the utility of bedside electromyography (EMG) in diagnosis and management of critical illness patients with suspected neuromuscular diseases.Methods Bedside EMG was performed in 34 critical illness patients with weakness and respiratory involvement,including segmental motor nerve conduction studies,sensory nerve conduction studies,F waves,concentric needle EMG and repetitive nerve stimulation.The clinical manifestations and clinical utility of bedside EMG in critical illness patients with suspected neuromuscular diseases were analyzed. Results EMG was normal in 5 patients.Low-frequency repetitive nerve stimulation showed decrement response of compound muscle action potential (CMAP) in 4 of 8 patients.Motor nerve conduction studies showed CMAP amplitude decreased in 73.3％(22/30) patients,and demyelinating changes was detected in 20.0％ (6/30)patients.F-wave persistence was 0 in 55.0％ (11/20) patients.Amplitude of sensory nerve action potential decreased in 28.6％ (6/21)patients.Bedside EMG could help to confirm or exclude diagnoses and guide the management in 82.4％(28/34) patients,confirm the diagnoses of peripheral neuropathy but have no effect on management in 11.8％ (4/34) patients,and bedside EMG was inconclusive in 2 patients.Conclusions Bedside EMG is useful for the diagnosis and management of critical ill with suspected neuromuscular diseases,while motor nerve conduction studies and repetitive nerve stimulation are more valuable.Individualized protocol for EMG studies should be made on the basis of clinical problem.

Objective:To explore the mediating effect of empowerment between self-perceived burden and medication adherence in kidney transplant recipients, so as to provide reference for improving medication adherence in kidney transplant recipients.Methods:This study was a cross-sectional survey. From August to December 2022, convenience sampling was used to select 240 kidney transplant recipients who were followed up at the Kidney Transplantation Center of Shanghai General Hospital as the research subject. A survey was conducted on subjects using the General Information Questionnaire, Self-Perceived Burden Scale (SPBS), Client Empowerment Scale (CES), and Basel Assessment of Adherence with Immunosuppressive Medication Scale (BAASIS) to analyze the correlation between patient self-perceived burden, empowerment, and medication compliance, as well as the mediating effect of empowerment between the two.Results:A total of 240 questionnaires were distributed, and 226 valid questionnaires were collected, with a valid response rate of 94.2% (226/240). Among 226 kidney transplant recipients, the total scores of SPBS, CES, and BAASIS were (27.34±8.03), (159.86±13.45), and (5.05±1.75), respectively. The SPBS score of the recipient was negatively correlated with the CES score ( r=-0.366, P<0.05), and positively correlated with the BAASIS score ( r=0.448, P<0.05). The CES score was negatively correlated with the BAASIS score ( r=-0.456, P<0.05). The above differences were statistically significant. Empowerment partially mediated the association between self-perceived burden and medication adherence in kidney transplant recipients, with a mediating effect ratio of 38.7%. Conclusions:Renal transplant recipients have poor medication adherence, and empowerment is a mediating variable between self-perceived burden and medication adherence. Medical and nursing staff should attach importance to and enhance the empowerment of kidney transplant recipients, in order to alleviate the negative impact of self-perceived burden, increase medication compliance of recipients, and improve their health outcomes.

Objective To summarize the characteristics of IgG4 related disease (IgG4-RD),and to avoid unnecessary surgical procedures due to misdiagnosis.Methods Retrospective analysis of the clinical data of one case of IgG4 related disease involving the renal pelvis in our hospital,and the clinical features of IgG4 related disease involving the renal pelvis were reviewed and discussed.A 56-year-old man presented with microscopic hematuria,CT showed right renal pelvis and ureteral wall thickening,local soft tissue density,post contrast CT showed low-density renal pelvic mass and the wall of the ureter-pelvic was irregularly thicken,indicating renal pelvic cancer and lymph node metastasis.PET-CT (18F-FDG) findings indicated that the renal pelvic mass was a malignant tumor,because the glucose metabolism was very high.The preoperative diagnosis was retroperitoneal lesion,suspecting renal pelvic carcinoma or lymphoma.The patient underwent 3D laparoscopic nephroureterectomy with out preoperative biopsy.During operation,we found extensive enlargement of the right renal portal and retroperitoneal lymph nodes,including that the renal portal and the renal pelvis mass had a serious adhesion to the vena cava and renal arterial vein.Results Postoperative pathology results revealed lymphatic tissue hyperplasia and germinal center formation.Immunohistochemical staining showed that most plasma cells positive expression of IgG4 (IgG4 ＞ 40％,IgG4 ＞ 100/HPF),reactive hyperplasia of lymph node,considering the IgG4 related diseases.Serum IgG4 level was 15.2 g/L (0.03-2.01 g/L)after operation.Combined with serological examination,IgG4 related disease was confirmed.There was no evidence of IgG4-related disease at any other site during the follow up period,thereby obviating the need for any additional therapy.Conclusions IgG4 related disease is a novel clinical disease entity characterized by elevated serum IgG4 concentration and tumefaction or tissue infiltration by IgG4-positive plasma cells,which leads to the enlargement of the organ or nodular/proliferative lesions.The disease can be revealed as a soft tissue tumor of the renal pelvis and be misdiagnosed as malignant tumor.Surgical intervention could be avoided according to the correct diagnosis.

With the development of modern sequencing techniques and bioinformatics, genomes that were once thought to be noncoding have been found to encode abundant functional micropeptides (miPs), a kind of small polypeptides. Although miPs are difficult to analyze and identify, a number of studies have begun to focus on them. More and more miPs have been revealed as essential for energy metabolism homeostasis, immune regulation, and tumor growth and development. Many reports have shown that miPs are especially essential for regulating glucose and lipid metabolism and regulating mitochondrial function. MiPs are also involved in the progression of related diseases. This paper reviews the sources and identification of miPs, as well as the functional significance of miPs for metabolism-related diseases, with the aim of revealing their potential clinical applications.

To investigate the degrees of EB virus reactivation in patients with inflammatory bowel disease (IBD) treated with different biologics and the levels of important cytokines associated with relapse under the influence of this virus, and to assess its diagnostic efficacy as a risk factor for identifying disease relapse. A case-control retrospective study based on patients′ hospitalization history data was conducted to select a total of 105 patients who were hospitalized in the Department of Gastroenterology, Huashan Hospital, Fudan University, with a confirmed diagnosis of IBD from 2021 to 2023. Based on the quantitative copy level of whole blood EBV DNA to determine the status of EB virus infection in patients, integrated cytokine 8 (IL-2, IL-4, IL-6, IL-10, IL-12p70, IL-17, TNF-α, IFN-γ), C-reactive protein, and fecal calreticulin, to find the risk variable associated with treatment relapse. Logistic regression was used to analyze the relative risk between this variable and treatment relapse, and ROC curves were used to predict the diagnostic efficacy of cytokine multifactorial thresholds for treatment relapse. Results showed that the median age of the study was 37(26, 54)years, with a minimum of 18 years and a maximum of 70 years, with a median age of 34(24, 51) years for Crohn′s Disease (CD) patients and 46(35, 60) years for Ulcerative colitis (UC) patients, with a statistically difference between the ages of the two groups ( t=2.675, P=0.009). The median age at 50 years of patients treated with Vedolizumab (VDZ) in the UC group was higher than in the treatment groups other than VDZ. The highest rate of EB virusreactivation was found in the group treated with immunosuppressants Azathioprine (AZA) combined with anti-tumor necrosis factor-α (anti-TNF-α) and VDZ (62.5% in both groups), and the lowest in the group treated with Ustekinumab (UST) (0%). IL-2 levels were elevated in the AZA+anti-TNF-α and anti-TNF-α groups after EB virus entryreactivation. Three treatment groups, AZA+anti-TNF-α, anti-TNF-α, and VDZ, had elevated levels of IL-6 expression after EB virus entry reactivation.In the anti-TNF-α treatment-related group IL-2was associated with treatment relapse in IBD ( OR=1.127, 95% CI: 1.044-1.256, P=0.007). ROC analysis showed that the AUC for IL-2 combined with EB virus in a replicative state was 0.8282 ( P=0.006), with a negative predictive value and a positive value of 90% and 75%, respectively. As well as IL-6 was associated with treatment relapse of IBD in the anti-TNF-αtreatment-related group as well as in the VDZ-treated group ( OR=1.049, 95% CI: 1.017-1.095, P=0.008). ROC analysis showed that the diagnostic sensitivity and specificity for post-treatment relapse at a critical value of 6.10 pg/ml for IL-6 was 83.33% and 82.93%, respectively. The AUC for IL-6 combined with EB virus in a replicative state was 0.900 ( P<0.000 1), with negative and positive predictive value of 84.09% and 73.33%, respectively. In summary, the imbalance of proinflammatory and anti-inflammatory cytokines varies between drugs, with EBV in a replication-activated state, combined with elevated levels of IL-2 as well as IL-6 expression being a risk factor for relapse in patients treated with anti-TNF-α-related drugs and VDZ.
