Objective To investigate the effect of varying ureteral wall thickness(UWT)at the site of ureteral stones on the clinical efficacy of ureteroscopic lithotripsy(URL).Methods The clinical data of 164 patients with ureteral stones in our hospital were retrospectively analyzed.According to different UWT,the patients were divided into the mild thickening group(84 cases,UWT<3.16 mm),the moderate thickening group(31 cases,UWT 3.16 to 3.49 mm),and the severe thickening group(49 cases,UWT>3.49 mm),and the differences of clinical related indicators among the three groups were compared.Results The incidence of postoperative renal colic and leukocyte disorder in the mild thickening group and the moderate thickening group were lower than those in the severe thickening group,and the differences were statistically significant(P<0.05).The postoperative catheterization time in the mild thickening group and the moderate thickening group were shorter than that in the severe thickening group,and the incidences of secondary lithotripsy,residual stones and stone return to kidney in the mild thickening group and the moderate thickening group were lower than those in the severe thickening group,with statistically significant differences(P<0.05).The length of hospital stay and hospitalization cost in the mild thickening group and the moderate thickening group were shorter/less than those in the severe thickening group,with statistically significant differences(P<0.05).Conclusion With the increase of UWT(especially when UWT>3.49 mm),the incidence of postoperative complications and hospitalization cost of URL increase to varying degrees,and the surgical efficacy decreases.In clinical work,UWT measurement holds potential value in predicting the surgical efficacy and complications of URL.

Objective:To understand the status quo of self-regulating fatigue (SRF) in aged patients undergoing maintenance hemodialysis (MHD) and analyze its influencing factors.Methods:This study is a cross-sectional study. From January to June 2022, 310 aged patients undergoing MHD from the blood purification centers of three ClassⅢ Grade A hospitals in Jinan, Shandong Province, were selected by convenience sampling. Various questionnaires, including the general information questionnaire, Mini-Mental State Examination (MMSE), Self-Regulatory Fatigue Scale (SRF-S), Medical Coping Modes Questionnaire (MCMQ), General Self-Efficacy Scale (GSES), and 5-Item Geriatric Depression Scale (GDS-5), were used to investigate and analyze the factors influencing self-regulation of fatigue in aged patients undergoing MHD through univariate and multiple stepwise regression analysis.Results:The SRF-S score for the aged patients undergoing MHD was (42.26±7.86). The results of the multiple factor analysis showed that family average monthly income, depression, coping style, and self-efficacy were factors influencing SRF in these patients ( P<0.05) . Conclusions:It is urgent to pay attention to the current status of self-regulation of fatigue in aged patients undergoing MHD and take effective measures to improve their self-efficacy, promote positive coping strategies, alleviate depression, and reduce their level of SRF.

Objective:To systematically evaluate the care experience of family caregivers for amyotrophic lateral sclerosis (ALS) patients, providing guidance for home care of ALS patients.Methods:Qualitative studies on the care experience of family caregivers for ALS patients were retrieved from PubMed, American Psychological Association Psychnet, CINAHL, Web of Science, Medline, Cochrane Library, Embase, China Biology Medicine disc, WanFang Data, VIP, and China National Knowledge Infrastructure. The search period was from database establishment to October 30, 2022. The quality of literature was evaluated using the quality evaluation criteria for qualitative research of the Australia Joanna Briggs Institute Evidence-Based Health Care Center (2016 edition). The aggregative integration method was used to integrate the results using NVivo 11 software.Results:A total of 11 studies were included. A total of 22 complete and clear results were extracted and combined to form eight new categories, which were integrated into three results, namely, family caregivers facing personal development limitations and various family difficulties, experiencing complex and chaotic emotional experiences, and craving for diversified care support.Conclusions:Nursing staff should pay attention to the impact of ALS on their patient's family caregivers, provide caregiver knowledge and skill guidance, promote positive emotional experiences, and offer diversified care support to improve the quality of life of patients and family caregivers.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective:To explore the distribution characteristics of memory B cells and its relationship with bone erosion in patients with rheumatoid arthritis (RA), and to further understand the mechanism of B cells in the pathogenesis of RA.Methods:B cell subsets in peripheral blood of 200 RA patients and 50 healthy individuals were detected by flow cytometry. According to the surface markers CD19, CD27 and lgD, B cells were divided into CD19 +CD27 +lgD - switched memory B cells, CD19 +CD27 +lgD + non-switched memory B cells, CD19 +CD27 -lgD - double-negative memory B cells and CD19 +CD27 -lgD + naive B cells. B cells in RA patients with various disease activity score, course of disease and treatment were analyzed. Patients were divided into four groups according to the results of joint ultrasonography, including patients without bone erosion, patients with hand bone erosion, patients with knee bone erosion and patients with hand and knee bone erosion. The relationship between the distribution of B cell subsets, autoantibodies and RA bone erosion were analyzed. Differences between the groups were analyzed by independent-samples t test, Mann-Whitney U test and χ2 test. The analysis of variance, Kruskal-Wallis analysis were used for multi-group comparison, Spearman correlation analysis was also used for correlation analysis. Results:①RA patients showed significantly decreased non-switched memory B cells [(9.5±6.7)% vs (12.1±4.7)%, t=2.46, P=0.015] and increased double negative memory B cells [(3.8±2.5)% vs(2.7±1.3)%, t=-4.74, P<0.001] in comparison to healthy individuals. The percentage of non-switched memory B cells were decreased in RA patients with moderate disease activity [(8.4±4.7 )% vs (12.4±7.5)%, t=3.13, P=0.001] and high disease activity [(7.8±7.6)% vs (12.4±7.5)%, t=3.00, P=0.003] in comparison to those in RA patients who achieved remission. Meanwhile, the na?ve B cells [(70.3±15.0)% vs (63.9±14.6)%, t=-2.15, P=0.034] were increased in RA patients with moderate disease activity. No difference was found in RA patients with different disease courses. Total B cells [(4.8±2.9)% vs (7.2±4.1)%, t=-3.24, P=0.001], non-switched memory B cells (7.6±4.3)% vs (10.0±7.1)%, t=-2.63, P=0.010) in RA patients who received prednisone treatment were decreased, while double-negative memory B cells (4.9±3.0)% vs (3.6±2.3)%, t=-2.79, P=0.006] were increased compared with those in RA patients without prednisone treatment. Non-switched memory B cells was decreased in RA patients with hand and knee erosion compared with RA patients without erosion [6.8%(2.5%, 9.5%) vs 9.7%(5.5%, 17.5%), Z=-2.12, P=0.034]. Double negative memory B cells in subgroup with keen erosion [3.3%(2.7%, 5.0%) vs 2.6%(1.9%, 3.8%), Z=-2.09, P=0.036]as well as with hand and knee erosion [3.9%(2.3%, 5.6%) vs 2.6%(1.9%, 3.8%), Z=-2.41, P=0.016] were higher than those in patients without erosion. In addition, higher serum RF level was found in subgroup RA patients with hand and knee erosion compared with subgroup of RA patients without erosion [141.0 (38.0, 874.0) U/ml vs 53.5 (10.0, 106.0)U/ml, Z=-2.07, P=0.039]. Meanwhile, the positive rate of ACPA in RA patients with bone erosion of hand was significantly higher than that of RA patients without bone erosion [81%(52/64) vs 64%(38/59), χ2=4.44, P=0.043). Conclusions:The results suggest that the increase of double negative memory B cells, the decrease of non-switched memory B cells and higher level of autoantibodies may closely relate to bone erosion of RA, which may be one of the pathogenesis of disability in RA.

Objective: To explore the development of the pancreatic surgeon technique in a high-volume center. Methods: A total of 284 cases receiving pancreatic surgery by a single surgeon from June 2015 to December 2020 were retrospectively included in this study. The clinical characteristics and perioperative medical history were extracted from the medical record system of Zhongshan Hospital,Fudan University. Among these patients,there were 140 males and 144 females with an age (M (IQR)) of 61.0 (16.8) years(range: 15 to 85 years). The "back-to-back" pancreatic- jejunal anastomosis procedure was used to anastomose the end of the pancreas stump and the jejunal wall. Thirty days after discharge,the patients were followed by outpatient follow-up or telephone interviews. The difference between categorical variables was analyzed by the Chi-square test or the CMH chi-square test. The statistical differences for the quantitative data were analyzed using one-way analysis of variance or Kruskal-Wallis H test and further analyzed using the LSD test or the Nemenyi test,respectively. Results: Intraoperative blood loss in pancreaticoduodenectomy between 2015 and 2020 were 300,100(100),100(100),100(0),100(200) and 150 (200) ml,respectively. Intraoperative blood loss in distal pancreatectomy was 250 (375),100 (50),50 (65), 50 (80),50 (50),and 50 (100) ml,respectively. Intraoperative blood loss did not show statistical differences in the same operative procedure between each year. The operative time for pancreaticoduodenectomy was respectively 4.5,5.0(2.0),5.5(0.8),5.0(1.3),5.0(3.3) and 5.0(1.0) hours in each year from 2015 to 2020,no statistical differences were found between each group. The operating time of the distal pancreatectomy was 3.8 (0.9),3.0 (1.5),3.0 (1.8),2.0 (1.1),2.0 (1.5) and 3.0(2.0) hours in each year,the operating time was obviously shorter in 2018 compared to 2015 (P=0.026) and 2020 (P=0.041). The median hospital stay in 2020 for distal pancreatectomy was 3 days shorter than that in 2019. The overall incidence of postoperative pancreatic fistula gradually decreased,with a incident rate of 50.0%,36.8%,31.0%,25.9%,21.1% and 14.8% in each year. During this period,in a total of 3,6,4,2,0 and 20 cases received laparoscopic operations in each year. The incidence of clinically relevant pancreatic fistula (grade B and C) gradually decreased,the incident rates were 0,4.8%,7.1%,3.4%,4.3% and 1.4%,respectively. Two cases had postoperative abdominal bleeding and received unscheduled reoperation. The overall rate of unscheduled reoperation was 0.7%. A patient died within 30 days after the operation and the overall perioperative mortality was 0.4%. Conclusion: The surgical training of a high-volume center can ensure a high starting point in the initial stage and steady progress of pancreatic surgeons,to ensure the safety of pancreatic surgery.

Objective:To investigate the changes in the morphology, structure and function of the bladders and their effects on the upper urinary tract dilatation(UUTD) after lumbosacral nerve transecting in rats.Methods:A total of 45 female SD rats were included, randomly divided into 3 groups with 15 rats in each group. Two groups were performed bilateral lumbar 6(L6) and cauda equina nerve shearing to establish neurogenic bladder(NB) model, which were nerve transected for 4 weeks(NB-4W) group and nerve transected for 12 weeks(NB-12W) group. Another group was performed bilateral L6 nerves and cauda equine exposing but not transecting, which was sham-operation (Sham) group. Cystometry and renal ultrasound examination were performed and rats in each group were killed to collect the kidney and bladder tissues in NB-4W group at 4 weeks, in Sham group and NB-12W group at 12 weeks after operation. HE, Masson staining, immunohistochemical staining and western blot were used to detect histological changes, expression of transforming growth factor-β1(TGF-β1) and α-smooth muscle actin(α-SMA).Results:All rats in NB-4W and NB-12W group showed acontractile detrusor. In the NB-4W and NB-12W group, the maximum cystometric capacity [(5.84±0.33) ml and (3.13±0.35) ml], the detrusor leak point pressure [(25.41±0.86) cm H 2O and (27.36±2.04) cm H 2O] (1 cm H 2O = 0.098 kPa), were significantly higher than those in the Sham group [(0.98±0.14) ml, (7.13±0.90) cm H 2O, both P<0.05]. Compliance in NB-4W group [(0.28±0.21) ml/cm H 2O] and NB-12W group [(0.17±0.12) ml/cm H 2O] were significantly lower than that of the Sham group [(0.34±0.26) ml/cm H 2O], and the compliance of NB-12W group was lower than that of NB-4W group significantly (all P<0.05). HE staining of the bladder showed that the inflammatory cell infiltration was obvious in the NB-4W and NB-12W group. Bladder collagen volume fractions in NB-4W group [(30.5±1.5) %] and NB-12W group [(45.2±3.8) %] were both higher than that of Sham group [(20.7±2.2) %, both P<0.05]. The expression of TGF-β1 and α-SMA in the bladder tissue of NB-4W group were higher than those of sham group, and that of NB-12W group were higher than NB-4W group. In NB-4W group and NB-12W group, 3 (20.0 %) and 7 (46.7 %) rats were found hydronephrosis, respectively. Additionally, HE staining showed that the degree of renal tubule injury and the number of inflammatory cell infiltration in the NB-4W and NB-12W group were higher than those in the Sham group. Masson staining showed that the volume fraction of collagen in kidneys of NB-4W and NB-12W group were (13.1±1.4) % and (21.6±1.9) %, respectively, which were significantly higher than that in sham operation group [(4.6±0.7) %, both P<0.05]. Conclusions:Bilateral L6 + cauda equina nerve transecting can induce NB with hydronephrosis in parts of rats. The degree of bladder fibrosis gradually increased with the time of nerve transection, and the incidence and severity of UUTD also increased with the time of nerve transection.

Objective Based on network pharmacology,molecular docking and animal experiment,this study explored the mechanism of Icariin combined with Prednisone in the treatment of steroid-resistant nephrotic syndrome(SRNS)in rats.Methods The targets of Icariin active components were determined by TCMSP,GeneCards and CTD databases.The targets of SRNS were screened from GeneCards,OMIM,CTD and DRUGBANK databases,Remove and integrate.Venn graph was drawn to obtain the intersection target.A protein-protein interaction network was constructed using STRING database,and core targets were screened by topological analysis using Cytoscape 3.7.2.DAVID 6.8 was employed for GO term enrichment and KEGG pathway enrichment.And AutoDockTools Vina,PyMOL for molecular docking.SRNS rat model was constructed.The body weight of rats was measured,The 24-hour urinary protein quantity was detected,and the pathological morphology of renal tissue was observed by HE staining.,and the expression of core target proteins was de tected by Western blot.Results Network pharmacologic analysis showed that 139 targets corresponding to Icariin active ingredients were obtained,and 58 common targets were obtained by intersection with 1476 SRNS related targets.In PPI network,the top three degree values were Akt,JUN and IL6.KEGG enrichment analysis showed that Icariin played a therapeutic role in SRNS mainly by PI3K/AKT singnaling pathway.Molecular docking verification showed that Akt,PI3K and autophagy-related protein LC3-II had good binding activity with Icariin.Animal experiment result showed that Icariin combined with Prednisone significantly increased the body weight of SRNS rats(P<0.05),decreased the 24 hour urine protein quantity(P<0.01),and improved the glomerular morphological changes.The results of Western-blotting showed that Icariin combined with Prednisone could significantly improve the abnormal decrease of LC3-II protein and the abnormal increase of Akt and PI3K protein expression in renal tissue of SRNS rats(P<0.01).Conclusion Icariin can play a role in the treatment of SRNS through a multi-target and multi-pathway,regulate the PI3K-Akt signaling pathway,and increase the autophagy activity of kidney tissue in SRNS rats,which may be one of its main mechanisms.

Objective:To investigate the current situation and influencing factors of humanistic care needs of family members of pregnant women in maternal intensive care unit, and to explore the relationship between humanistic care needs of family members of pregnant women in maternal intensive care unit, relocation stress level and perceived social support ability, so as to provide a basis for clinical nursing staff to implement targeted humanistic care for family members of pregnant women in maternal intensive care unit.Methods:From July to December 2022, 267 family members of pregnant women who were observed in the Maternal Intensive Care Unit of Maternity Hospital Affiliated to Nanjing Medical University/Nanjing Maternal and Child Health Hospital were selected as the research objects by the convenient sampling method. The general information questionnaire, Humanistic Care Needs Scale for Family Members of Pregnant Women in the Obstetric Intensive Care Unit, Family Relocation Stress Scale for Intensive Care Unit Patients and Perceived Social Support Scale were used to carry out a cross sectional investigation.Results:The scores of humanistic care needs, relocation stress scale and perceived social support scale were (175.32 ± 16.04), (35.12 ± 8.11), (57.30 ± 15.43) points, respectively. The length of maternal intensive care unit stay ( B=1.301, P<0.05), the family′s role changed for the first time ( B=2.328, P<0.05), the delivery mode doesn′t match the family′s expectations ( B=-2.407, P<0.05), maternal admission to maternal intensive care unit due to childbirth complications ( B=3.228, P<0.05), relocation stress level of intensive care unit patients′ family members ( B=0.891, P<0.05), and family members′ perceived social support ability ( B=0.461, P<0.05) were the influencing factors of humanistic care needs of maternal family members in maternal intensive care unit factors, which explained 83.2% of the total variation. Conclusions:The humanistic care needs of family members of pregnant women in maternal intensive care unit are at a high level. Medical staff should pay more attention to the family members of pregnant women who stay in maternal intensive care unit for a long time, undergo role change for the first time, have unexpected delivery mode and stay in maternal intensive care unit due to childbirth complications, so as to provide them with more comprehensive humanistic care and establish multiple support system, in order to improve the level of humanistic care for the family members of maternal intensive care unit.

Objective:To investigate the clinical efficacy of 3D printed guide plate-assisted hematoma puncture and catheter drainage in the treatment of a moderate volume of hypertensive intracerebral hemorrhage in the basal ganglia.Methods:The clinical data of 42 patients with a moderate volume of hypertensive intracerebral hemorrhage in the basal ganglia who received treatment with 3D printed guide plate-assisted hematoma puncture and catheter drainage in Dazhu Hospital of North Sichuan Medical College from January 2016 to January 2021 were retrospectively analyzed. In the traditional puncture group, there were 19 patients who received traditional punctures according to preoperative cranial CT findings (traditional puncture group). In the 3D printed guide plate puncture group, there were 23 patients who received hematoma puncture and catheter drainage assisted by a 3D printed guide plate. Preoperative preparation time (from admission to operation), operative time, the number of hematoma punctures, hematoma clearance rate, postoperative indwelling time of drainage tube, residual hematoma rate, the occurrence of puncture canal bleeding, intracranial infection, Glasgow Coma Scale score measured at 3 and 7 days after surgery, and Glasgow Outcome Scale score measured at 1, 3 and 6 months after surgery were compared between the two groups.Results:There were no significant differences in preoperative preparation time and operative time between the two groups ( t = 0.25, 0.40, both P > 0.05). 3D-printed guide plate-assisted hematoma puncture reduced the probability of reveiving one more hematoma puncture during the surgery. There was no significant difference in the number of hematoma puncture between the two groups ( χ2= 0.48, P > 0.05). There were no significant differences in the probabilities of puncture canal bleeding and intracranial infection between the two groups ( χ2 = 0.05, 0.03, both P > 0.05). Postoperative indwelling time of the drainage tube in the 3D printed guide plate puncture group was significantly shorter than that in the traditional puncture group [(3.10 ± 0.38) vs. (3.46 ± 0.52) days, t = 2.65, P < 0.05]. The residual hematoma rate in the 3D printed guide plate puncture group was significantly lower than that in the traditional puncture group [(32.04 ± 5.33)% vs. (37.37 ± 5.51)%, χ2 = 3.20, P < 0.05]. There were significant differences in Glasgow Coma Scale score measured at 3 and 7 days after surgery between the two groups [(12.04 ± 1.19) points vs. (11.26 ± 0.93) points, (13.65 ± 0.88) points vs. (12.94 ± 0.97) points, t = 2.33, 2.46, both P < 0.05]. Glasgow Outcome Scale score measured at 1, 3, and 6 months after surgery in the 3D printed guide plate puncture group was 18, 21, and 22 points, respectively, which was significantly higher than 9, 11, and 12 points in the traditional puncture group ( χ2 = 4.34, 4.69, 5.17, all P < 0.05). Conclusion:3D printed guide plate assisted hematoma puncture and catheter drainage for treatment of a moderate volume of hypertensive intracerebral hemorrhage in the basal ganglia can increase the accuracy of puncture, decrease hematoma residual rate, improve short- and long-term prognosis, does not prolong preoperative preparation time. Moreover, it costs low, is safe, and is easy to learn.
