Pruritus is one of the common comorbidities in patients with chronic kidney disease, significantly reducing life quality and increasing the risks of depression and mortality. This report presents the treatment process of a patient undergoing maintenance hemodialysis with pruritus. The patient successively received an optimized dialysis prescription, management of chronic kidney disease-related mineral and bone disorder, correction of secondary hyperparathyroidism, enhanced skin care, and administration of gabapentin. However, pruritus symptoms of this patient persisted. Subsequently, the patient was treated with nalfurafine hydrochloride, resulting in significant relief of pruritus symptoms without any adverse reaction. This case provides new insights and references for the treatment of chronic kidney disease-associated pruritus.

Objective To establish a high-throughput non-targeted screening and prioritization method for emerging pollutants(EPs)in sewage using direct injection high-resolution mass spectrometry(HRMS).Methods The sewage samples were filtered by membrane filter and directly subjected to the liquid chromatography-time-of-flight mass spectrometer based on a method modified from our previous study.A C18 chromatographic column was applied for a gradient elution separation,and accurate mass and mass spectral fragment information were obtained through the MS full scan mode and MS/MS DIA data collection mode.After peak detection and alignment,the features from the raw data through open source software MZmine 3,and then high-throughput screening strategies such as MassBank and PubChem databases were used for compound annotation.Finally,the candidate features were confirmed with chemical standards by compared their retention time and mass spectrum fragmentation ion peaks.Results 13 EPs were identified,including 7 industrial chemicals,4 pharmaceuticals,1 pesticide and 1 metabolite.High detection rates were observed for metformin(86.2％),2-hydroxybenzothiazole(79.3％),1,2-benzisothiazole-3-one(72.4％),and 1,2-benzisothiazole-3-one(72.4％).The quantitative concentration range of EPs was 1.37～19.05 ng/mL,with the high concentrations observed for melamine(19.05 ng/mL)and furosemide(18.49 ng/mL).Ecological risk assessment identified 1,2-benzisothiazol-3-one,4-aminoacetophenone,creatinine,2-hydroxybenzothiazole,and furosemide as key pollutants.Conclusion This direct injection coupled with HRMS workflow enables efficient non-targeted screening and prioritization of emerging EPs in sewage samples,highlighting five ecotoxicologically critical EPs.The methodology enhances environmental monitoring capabilities and provide critical technical support for interdisciplinary research such as environmental forensics and health risk assessment.

Henoch-Sch?nlein purpura is also known as IgA vasculitis. The kidney involvement, namely Henoch-Sch?nlein purpura nephritis (HSPN), is one of IgA vasculitis's main clinical manifestations. Galactose-deficient IgA1 plays an important role in the pathogenesis of HSPN, which not only is similar to the "four-hits hypothesis" of IgA nephropathy, leading to IgA1 deposit in the mesangial region of the kidney, but also is closely related to inflammation with more complicated compositions of its immune complex. Therefore, abnormal glycosylation of IgA1 is expected to be a biomarker for diagnosis and prediction of HSPN pathogenesis, disease activity determination and prognosis prediction. Here, the paper reviews the research progress on the pathogenesis and clinical application of abnormal glycosylation of IgA1 in HSPN.

【Objective】 To investigate the efficacy of the adjustable "paper clip" techniques in the suture of dorsal vein complex (DVC) and retention of urethral function in robot-assisted laparoscopic radical prostatectomy (RALRP). 【Methods】 A total of 30 cases of prostate cancer treated with RALRP were enrolled, all of which used the adjustable "paper clip" techniques. During operation, the DVC was sewed with barbed suture, and then a reverse suture was made through two sides of the prostatic ligaments. A Hem-o-lock was used to fasten the suture, which would be flexible to control the degree of tightness for the ligature. Perioperative and follow-up data of urinary continence and symptoms were collected and analyzed. 【Results】 All operations were successful. The estimated blood loss was (123.3±80.7) mL, 53.6% patients recovered continence in 1 month, and the continence rate increased to 92.9% and 96.3% at month 3 and 6. 92.9 of patients had no risk of incontinence 3 months after surgery. 【Conclusion】 The adjustable "paper clip" techniques have advantages in reducing blood loss, maintaining clear surgical field, preserving urethral function, and improving urinary continence.

Objective:To observe the effect of non-vitrectomy in the treatment of idiopathic macular epiretinal membranes (IMEM).Methods:This study is a randomized controlled trial. From December 2017 to December 2018, 60 IMEM patients (60 eyes) diagnosed in Weifang Eye Hospital were included in the study. BCVA, intraocular pressure (IOP) and OCT were performed in all patients. The BCVA examination was performed using the international standard visual acuity chart, which was converted to logMAR. The CMT was measured by OCT. According to the surgical methods, the patients were divided into non-vitrectomy group and control group, 30 patients (30 eyes) in each group. The age ( t=1.723), logMAR BCVA ( t=1.703), CMT ( t=-0.956), IOP ( t=-1.434) were not significantly different between the two groups ( P=0.090, 0.094, 0.343, 0.157). 23G vitreous cutting system was used in all eyes. The macular epiretinal membranes was removed by non-vitrectomy in the non-vitrectomy group and by vitrectomy in the control group. The relevant examination with the same equipment and methods before the operation at 1 week and 1, 3, 6 months after operation. The time of surgery, the changes of BCVA, CMT and postoperative complications in the two groups were observed comparatively. Variance analysis of repeated measurements was performed for the comparison of BCVA, CMT and IOP after surgery in the two groups. Wilcoxon rank sum test of two independent samples was performed for the degree of vision improvement. The incidence of postoperative complications was compared by χ2 test. Results:At 6 months after operation, BCVA increased in 24 eyes (80%) and unchanged in 6 eyes (20%) in the non-vitrectomy group. Compared with preoperative BCVA, the difference was statistically significant ( P<0.05). BCVA increased in 25 eyes (83.4%), unchanged in 4 eyes (13.3%) and decreased in 1 eye (3.3%) in the control group. Compared with preoperative BCVA, the difference was statistically significant ( P<0.05). There was no significant difference between the two groups in BCVA improvement degree after operation ( Z=-0.26, P>0.05). At 6 months after operation, the average logMAR BCVA was statistically significant compared with the preoperative in the non-vitrectomy group ( P=0.002, 0.005) and control group ( P=0.004, <0.001). Visual stability occurred 1 month after operation in the non-vitrectomy group and 3 months after operation in the control group. The effective operative time of the non-vitrectomy group and control group was 4.50±1.41 and 15.50±2.33 min, respectively. The difference of effective operation time between the two groups was statistically significant ( t=-22.12, P <0.05). After surgery, no significant complications were found in the non-vitrectomy group. In the control group, there were 3 eyes with low IOP and 1 eye with macular hole during operation. Conclusions:Non-vitrectomy and vitrectomy have similar effects on IMEM. Non-vitrectomy has short effective operation time, faster recovery after surgery and no obvious complications.

Objective To study the status of filial piety and anxiety among adults, explore the relationship between filial piety and anxiety, and analyze the factors that affect anxiety. Methods A total of 915 adults from Jiangsu and Anhui provinces were selected using the General Information Questionnaire, the Chinese Filial Values Index scale (FVI) and Zung Self-rating Anxiety Scale (SAS), through the online platform and on-site payment, recovery of the questionnaire to investigate. Results The overall level of filial piety was 85.23 ± 9.22 , among which the care dimension was 84.60 ± 9.75 and the respect dimension was 86.12 ± 11.76;111 adults were with anxiety (12.13％), and patients with mild and moderate anxiety respectively were 88 (9.62％) and 23 (2.51％) cases. The overall level of filial piety was negatively correlated with the level of anxiety (r=-0.403, P<0.01), and the level of filial piety is an independent factor affecting the level of anxiety in adults(B=-0.299,P<0.01). Other factors also include the quality of sleep, illness, duration, beliefs, occupational stability. Conclusion The high level of filial piety in adults is moderately correlated with anxiety and is an independent risk factor for anxiety in this population. The adult's education of filial piety should be strengthened and the positive adjustment of filial piety to anxiety should be strengthened in order to better solve the physical and mental health problems caused by the pension burden.
