ABSTRACT

Neonatal seizures are the most common clinical manifestations of critically ill neonates and often suggest serious diseases and complicated etiologies. The precise diagnosis of this disease can optimize the use of anti-seizure medication, reduce hospital costs, and improve the long-term neurodevelopmental outcomes. Currently, a few artificial intelligence-assisted diagnosis and treatment systems have been developed for neonatal seizures, but there is still a lack of high-level evidence for the diagnosis and treatment value in the real world. Based on an artificial intelligence-assisted diagnosis and treatment systems that has been developed for neonatal seizures, this study plans to recruit 370 neonates at a high risk of seizures from 6 neonatal intensive care units (NICUs) in China, in order to evaluate the effect of the system on the diagnosis, treatment, and prognosis of neonatal seizures in neonates with different gestational ages in the NICU. In this study, a diagnostic study protocol is used to evaluate the diagnostic value of the system, and a randomized parallel-controlled trial is designed to evaluate the effect of the system on the treatment and prognosis of neonates at a high risk of seizures. This multicenter prospective study will provide high-level evidence for the clinical application of artificial intelligence-assisted diagnosis and treatment systems for neonatal seizures in the real world.

ABSTRACT

Objective To screen the potential key genes of osteosarcoma by bioinformatics methods and analyze their immune infiltration patterns. Methods The gene expression profiles GSE16088 and GSE12865 associated with osteosarcoma were obtained from the Gene Expression Omnibus(GEO),and the differentially expressed genes(DEGs)related to osteosarcoma were screened by bioinformatics tools.Gene Ontology(GO)annotation,Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment,and analysis of immune cell infiltration were then carried out for the DEGs.The potential Hub genes of osteosarcoma were identified by protein-protein interaction network,and the expression of Hub genes in osteosarcoma and normal tissue samples was verified via the Cancer Genome Atlas(TCGA). Results A total of 108 DEGs were screened out.GO annotation and KEGG pathway enrichment revealed that the DEGs were mainly involved in integrin binding,extracellular matrix (ECM) structural components,ECM receptor interactions,and phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt)signaling pathway.Macrophages were the predominant infiltrating immune cells in osteosarcoma.Secreted phosphoprotein 1(SPP1),matrix metallopeptidase 2(MMP2),lysyl oxidase(LOX),collagen type V alpha(II)chain(COL5A2),and melanoma cell adhesion molecule(MCAM)presented differential expression between osteosarcoma and normal tissue samples(all P<0.05). Conclusions SPP1,MMP2,LOX,COL5A2,and MCAM are all up-regulated in osteosarcoma,which may serve as potential biomarkers of osteosarcoma.Macrophages are the key infiltrating immune cells in osteosarcoma,which may provide new perspectives for the treatment of osteosarcoma.

ABSTRACT

OBJECTIVE@#This study aimed to investigate the effects of caprylic acid (C8:0) on lipid metabolism and inflammation, and examine the mechanisms underlying these effects in mice and cells.@*METHODS@#Fifty-six 6-week-old male C57BL/6J mice were randomly allocated to four groups fed a high-fat diet (HFD) without or with 2% C8:0, palmitic acid (C16:0) or eicosapentaenoic acid (EPA). RAW246.7 cells were randomly divided into five groups: normal, lipopolysaccharide (LPS), LPS+C8:0, LPS+EPA and LPS+cAMP. The serum lipid profiles, inflammatory biomolecules, and ABCA1 and JAK2/STAT3 mRNA and protein expression were measured.@*RESULTS@#C8:0 decreased TC and LDL-C, and increased the HDL-C/LDL-C ratio after injection of LPS. Without LPS, it decreased TC in mice ( P < 0.05). Moreover, C8:0 decreased the inflammatory response after LPS treatment in both mice and cells ( P < 0.05). Mechanistic investigations in C57BL/6J mouse aortas after injection of LPS indicated that C8:0 resulted in higher ABCA1 and JAK2/STAT3 expression than that with HFD, C16:0 and EPA, and resulted in lower TNF-α, NF-κB mRNA expression than that with HFD ( P < 0.05). In RAW 264.7 cells, C8:0 resulted in lower expression of pNF-κBP65 than that in the LPS group, and higher protein expression of ABCA1, p-JAK2 and p-STAT3 than that in the LPS and LPS+cAMP groups ( P < 0.05).@*CONCLUSION@#Our studies demonstrated that C8:0 may play an important role in lipid metabolism and the inflammatory response, and the mechanism may be associated with ABCA1 and the p-JAK2/p-STAT3 signaling pathway.

ABSTRACT

The paper introduces professor MA Hui-fang's experience in age-related macular degeneration treated with acupuncture at Jingming (BL 1). It is believed that the basic pathogenesis of this disease refers to liver and kidney insufficiency and weakness of spleen qi. Based on the academic ideas of yang qi and meridian-collateral system, the treatment principle is proposed as "invigorating yang qi, replenishing the liver and kidney and nourishing the spleen and stomach". Regarding acupoint selection, Jingming (BL 1) is specially used, combined with the 4 front-mu points (Zhongwan [CV 12], Guanyuan [CV 4] and bilateral Tianshu [ST 25]), as well as the empirical points for eye diseases (Jingming [BL 1], Baihui [GV 20] and Zulinqi [GB 41]). Concerning to needling technique, shuci (transport needling), fenci (intermuscular needling) and yuandaoci (distal needling) are dominated. Eventually, a set of unique therapeutic method has been accumulated through professor MA Hui-fang's clinical practice in treatment of age-related macular degeneration.

ABSTRACT

Objective To analyze the incidence and risk factors of colorectal adenomatous polyps (CAP) in recipients after liver transplantation. Methods Seventy-seven liver transplant recipients and 231 individuals undergoing colonoscopy during physical examination were recruited in this study. The incidence of CAP and pathological examination results were analyzed. Clinical data of liver transplant recipients were collected. According to the incidence of CAP, liver transplant recipients were divided into the CAP group (n=28) and non-CAP group (n=49). The risk factors of CAP after liver transplantation were identified. Results The 5-year cumulative incidence rates of colorectal polyps in liver transplant recipients and physical examination individuals were 43% and 34%, and 29% and 23% for the 5-year cumulative incidence rates of CAP, with no significant differences (both P > 0.05). Among all liver transplant recipients, 65 polyps were detected. The quantity of polyps in 1 case was excessively high and not counted. Multiple polyps were identified in certain recipients. Five polyps were not prepared for pathological examination due to small size. Pathological examination of 60 polyps demonstrated 25 inflammatory polyps, 33 CAP (8 complicated with low-grade intraepithelial neoplasia and 3 complicated with high-grade intraepithelial neoplasia), and 2 well-differentiated adenocarcinoma. Cox model analysis prompted that use of ciclosporine after liver transplantation was an independent risk factor for CAP in the recipients. Conclusions The risk of CAP is slightly elevated after liver transplantation. Postoperative use of ciclosporine is an independent risk factor for CAP in recipients after liver transplantation. Colonoscopy should be emphasized in the recipients after liver transplantation.

ABSTRACT

Objective To investigate the value of neutrophil-to-lymphocyte ratio (NLR), red blood cell distribution width-to-lymphocyte ratio (RLR), and lymphocyte-to-monocyte ratio (LMR) in predicting the prognosis of early small hepatocellular carcinoma (HCC) after radiofrequency ablation (RFA). Methods A retrospective analysis was performed for 132 patients newly diagnosed with early HCC who underwent RFA in Tianjin Second People's Hospital from September 2011 to December 2020. Preoperative data were collected and the patients were followed up to observe recurrence and overall survival (OS). The X-tile tool was used to determine the optimal cut-off values of NLR, RLR, and LMR based on 5-year survival rate and recurrence-free survival (RFS) rate, and then the patients were divided into N-R-L 0 group with 92 patients, N-R-L 1 group with 29 patients, and N-R-L 2 group with 11 patients. The chi-square test was used for comparison of categorical data between the three groups. The Kaplan-Meier method was used to plot the survival curve, and the log-rank test was used to compare RFS and OS rates between groups. The factors with statistical significance in the log-rank test were included in the multivariate Cox regression analysis to determine the risk factors for RFS and OS rates. Results There were significant differences in Child-Pugh class and albumin between the N-R-L 0, N-R-L 1, and N-R-L 2 groups ( χ 2 2=10.992 and 5.699, both P < 0.05). The 1-, 3-, and 5-year OS rates of the three groups were 100%/96.3%/90.7%, 96.6%/60.4%/41.3%, and 81.8%/46.8%/15.6%, respectively ( χ 2 =38.46, P < 0.000 1), and the 1-, 3-, and 5-year RFS rates of the three groups were 76.9%/52.5%/33.3%, 42.9%/13.1%/0, and 11.1%/0/0, respectively ( χ 2 =35.345, P < 0.000 1). The multivariate Cox regression analysis showed that tumor diameter ≥ 2 cm (hazard ratio[ HR ]=2.10, 95% confidence interval[ CI ]: 1.28-3.43, P =0.003; HR =3.67, 95% CI : 1.58-8.52, P =0.002), N-R-L score of 1 point ( HR =3.14, 95% CI : 1.81-5.46, P < 0.000 1; HR =8.27, 95% CI : 3.15-21.71, P < 0.000 1), and N-R-L score of 2 points ( HR =2.61, 95% CI : 1.06-6.42, P =0.037; HR =14.59, 95% CI : 3.96-53.78, P < 0.000 1) were independent predictive factors for RFS and OS. Conclusion N-R-L, a systemic inflammatory response marker composed of NLR, RLR, and LMR, is an independent risk factor for recurrence and survival of early small HCC after RFA, and it can be used as a useful noninvasive biomarker in combination with tumor features to predict the recurrence and survival of early HCC after RFA.

ABSTRACT

Chemoimmunotherapy has attracted much attention as an emerging therapy pattern for the treatment of cancers. Exploring effective drug combination schemes and reasonable delivery methods remained the key issue in current research. Herein, we designed sorafenib (SF) and anti-Tim-3 monoclonal antibody (Tim-3 mAb) co-loaded MMP2-responsive mesoporous silica nanoparticles (ST-MSNs) for combined chemoimmunotherapy of hepatocellular carcinoma (HCC). The shell of ST-MSNs was fabricated by Tim-3 mAb through matrix metalloproteinase 2 (MMP2) sensitive peptides as "gatekeepers" to prevent drug release during the blood circulation. In tumor microenvironment, the high levels of MMP2 caused the responsive shedding of Tim-3 mAb, leading to the triggerred release of SF and Tim-3 mAb. Then, SF could be delivered to tumor cells and Tim-3 mAb could be delivered to T cells, respectively. In vivo tumor inhibition study results demonstrated that ST-MSNs can significantly enhance synergistic antitumor activity compared with sequential administration of free SF solution and Tim-3 mAb solution. Meanwhile, the expression of antitumor cytokines IFN-γ, IL-12 and the percentage of CD3+CD4+ cells, CD3+CD8+ cells in tumors were upregulated after the administration of ST-MSNs, demonstrating good immunomodulatory ability. In addition, within the dosage range, the ST-MSNs had low cytotoxicity and hemolysis, and no obvious tissue toxicity was observed. All animal experiments were performed in line with national regulations and approved by the Animal Experiments Ethical Committee of Shandong University. In conclusion, this study provided a promising drug combination of chemoimmunotherapy with good application prospects for clinical HCC treatment, and exhibited a potential drug carrier for clinical chemoimmunotherapy.

ABSTRACT

@#AIM: To observe the location characteristics of the earliest tear film breakup in elderly patients with dry eyes.METHODS: Cross-sectional study. The 154 elderly patients with dry eyes in our hospital from July 2019 to December 2019 were included, with 143 right eyes, 124 left eyes, and 71 patients were males, 83 patients were females, aged 68-90(mean: 73.40±4.13)years old. The location of the earliest tear film breakup was investigated by using corneal topographer. The cornea was separated to four sectors to record the earliest tear film breakup location by anticlockwise order. The sector corresponding to the right eye was nasal superior, temporal superior, temporal inferior and nasal inferior respectively. And it corresponding to the left eye was temporal superior, nasal superior, nasal inferior and temporal inferior respectively. Then the sector which was the earliest tear film breakup location was recorded. At the same time, the distance which was from the earliest tear film breakup location to the centre of cornea was recorded too.RESULTS: The highest constituent ratio of area of right eye was nasal inferior(28.7%), then was temporal inferior(27.3%), nasal superior(20.3%), temporal superior(11.2%), and the constituent ratio of earliest tear film breakup occurred in 2-3 areas at the same time was 12.6%. The constituent ratio of the earliest tear film breakup area of left eye also was nasal inferior(31.5%), then was temporal inferior(25.0%), nasal superior(23.4%), temporal superior(11.3%), the constituent ratio of earliest tear film breakup occurred in 2-3 areas at the same time was 8.9%. There was no difference in the constituent ratio of tear film breakup area between two eyes(χ2=1.443, <i>P</i>=0.837). The distance from the earliest tear film breakup area of the nasal inferior quadrant to the centre of cornea was mostly the zone from 1.5-2mm and 2-2.5mm in both eyes.CONCLUSION: There is a certain regularity in the characteristics of tear film breakup area in elderly patients with dry eyes, and the earliest tear film breakup area of both eyes is mainly occurred in nasal inferior, and there is no significant difference between two eyes.

ABSTRACT

OBJECTIVE@#To explore the regulatory function of RNA binding motif protein 38 (RBM38) in human acute myeloid leukemia cells HL-60 and its mechanism.@*METHODS@#The lentivirus carriers of overexpressed and knockdown RBM38 were constructed. After HL-60 cells were transfected, Western blot was used to analyze the expression level of RBM38 in HL-60 cells. The cell proliferation and cycle of HL-60 were detected by CCK-8 assay and flow cytometry assay, respectively. RNA immunoprecipitation coupled real-time PCR (RIP-qPCR) was used to detect the combination of RBM38 with mRNAs. Actinomycin D treatment followed by real-time PCR (AcD-qPCR) was used to detect the effect of RBM38 on the stability of target mRNAs.@*RESULTS@#RBM38 in HL-60 cells was overexpressed or inhibited by lentivirus transduction. Overexpressed RBM38 promoted the cell cycle and proliferation of HL-60, while RBM38 knockdown repressed the two processes. RBM38 showed an interaction with FZD1 mRNA and enhancement of its stability.@*CONCLUSION@#RBM38 can regulate cell proliferation of HL-60 by improving the stability of FZD1 mRNA.

ABSTRACT

OBJECTIVES@#This study aims to evaluate the endo-sinus bone remodeling of dental implants placed via osteotome sinus floor elevation (OSFE) after 6 months and using different implant protrusion lengths and bone grafts through cone beam computed tomography (CBCT).@*METHODS@#Ninety-six patients with 124 implants were included and assigned into four groups. Group 1: implant protrusion length4 mm with bone graft; group 3: implant protrusion length4 mm without bone graft. Apical bone gain (ABG), cortical bone gain (CBG), bone density gain (BDG), and marginal bone loss (MBL) were observed and analyzed at baseline and 6 months after implant surgery.@*RESULTS@#The CBG in grafted groups 1 and 2 was higher than that in non-grafted groups. The ABG and BDG were higher in non-grafted groups 3 and 4 than in grafted groups, and the levels in group 3 were higher than those in group 4. The CBG in grafted group 2 was higher than that in group 1. No significant difference was observed in MBL analysis.@*CONCLUSIONS@#The BDG of IPL4 mm implant when bone grafts were not applied. No relevance was observed between IPL and CBG. Bone grafts can accelerate endo-sinus bone remodeling by increasing CBG and dissipating the influence of IPL on BDG.

ABSTRACT

BACKGROUND@#Microribose nucleic acids (miRNAs) are implicated in the progression of lung adenocarcinoma. MicroRNA-345-5p (miR-345-5p) is a recently identified anti-oncogene in some human cancers, but its functional role and possible molecular mechanism in lung adenocarcinoma remain unknown. This study aimed to identify the biological function and underlying mechanism of miR-345-5p in lung adenocarcinoma cells.@*METHODS@#In this study, lung adenocarcinoma tissues and adjacent tissues were collected in the First Affiliated Hospital of Anhui Medical University between April 2016 and February 2017. The expression of miR-345-5p and ras homolog family member A (RhoA) in lung adenocarcinoma tissues and human lung adenocarcinoma cell lines (A549, H1650, PC-9, and H441) was detected by reverse transcription quantitative polymerase chain reaction analysis. Functional assays including colony formation, flow cytometry analysis, wound healing, and transwell assays were performed to assess the proliferation, apoptosis, migration, and invasion of lung adenocarcinoma cells. In addition, RNA pulldown and luciferase reporter assays were conducted to evaluate the relationship between miR-345-5p and RhoA. Difference between the two groups was analyzed with Student's t test, while that among multiple groups was analyzed with one-way analysis of variance.@*RESULTS@#MiR-345-5p expression displayed lower level in lung adenocarcinoma tissues (0.241 ± 0.095 vs.1.000 ± 0.233, t = 19.247, P < 0.001) and cell lines (F = 56.992, P < 0.001) than control tissues and cells. Functional experiments demonstrated that upregulation of miR-345-5p inhibited the malignant phenotypes of lung adenocarcinoma cells via suppressing cell proliferation, migration, invasion, and facilitating cell apoptosis. Additionally, RhoA was verified to be the downstream target of miR-345-5p. Expression of RhoA was downregulated by overexpression of miR-345-5p in PC-9 (0.321 ± 0.047 vs. 1.000 ± 0.127, t = 8.536, P < 0.001) and H1650 (0.398 ± 0.054 vs. 1.000 ± 0.156, t = 4.429, P = 0.011) cells. Rescue assays revealed that overexpression of RhoA rescued the suppressive effects of miR-345-5p upregulation on proliferation, migration, and invasion of lung adenocarcinoma cells. Further, miR-345-5p was found to regulate the Rho/Rho-associated protein kinase (ROCK) signaling pathway by downregulation of RhoA in lung adenocarcinoma cells.@*CONCLUSIONS@#MiR-345-5p plays a tumor suppressor role in lung adenocarcinoma cells by downregulating RhoA to inactivate the Rho/ROCK pathway.

ABSTRACT

Penile length shortening and erectile dysfunction are common complications after radical prostatectomy. Various methods have been used to maintain erectile function, but less attention has been paid to preserving penis length. N-acetylcysteine (NAC) has the effect of antioxidation and antifibrotic, which may be beneficial to improve those postoperative complications. This study investigated the effect of NAC on maintaining the penile length and the erectile function after bilateral cavernous nerve crush (BCNC) and its underlying mechanism. Twenty-four male rats were randomly divided into three groups: control group, BCNC group, and BCNC + NAC group. NAC or equal volume of saline was daily administrated by intragastric gavage for 4 weeks. The initial and end penile lengths were measured. Intracavernosal pressure/mean arterial pressure (ICP/MAP) ratio was calculated to assess erectile function. Hematoxylin-eosin staining, Masson's trichrome staining, immunohistochemistry, and Western blot were performed to explore cellular and molecular changes of the penis. Compared to the BCNC group, the penile length, ICP/MAP ratio and smooth muscle/collagen ratio in the BCNC + NAC group were improved significantly (all P < 0.05), and the expressions of endothelial nitric oxide synthase, α-smooth muscle actin, glutathione, and glutathione peroxidase 1 were significantly increased after NAC treated (all P < 0.05), along with the decreased expressions of hypoxia-inducible factor-1α, transforming growth factor-β1, collagen I, collagen III, collagen IV, malonaldehyde, and lysine oxidase (all P < 0.05). This study demonstrated that NAC could maintain penile length and partly improve erectile function. Possible mechanism is directly and/or indirectly related to antihypoxic and antifibrosis.

ABSTRACT

Background and Objectives@#Manipulating different signaling pathways via small molecules could efficiently inducecardiomyocytes from human induced pluripotent stem cells (hiPSC). However, the effect of transcription factors on the hiPSC-directed cardiomyocytes differentiation remains unclear. Transcription factor, p53 has been demonstrated indispensable for the early embryonic development and mesendodermal differentiation of embryonic stem cells (ESC).We tested the hypothesis that p53 promotes cardiomyocytes differentiation from human hiPSC. @*Methods@#and Results: Using the well-characterized GiWi protocol that cardiomyocytes are generated from hiPSC via temporal modulation of Wnt signaling pathway by small molecules, we demonstrated that forced expression of p53 in hiPSC remarkably improved the differentiation efficiency of cardiomyocytes from hiPSC, whereas knockdown endogenous p53 decreased the yield of cardiomyocytes. This p53-mediated increased cardiomyocyte differentiation was mediated through WNT3, as evidenced by that overexpression of p53 upregulated the expression of WNT3, and knockdown of p53 decreased the WNT3 expression. Mechanistic analysis showed that the increased cardiomyocyte differentiation partially depended on the amplified mesendodermal specification resulted from p53-mediated activation of WNT3-mediated Wnt signaling. Consistently, endogenous WNT3 knockdown significantly ameliorated mesendodermal specification and subsequent cardiomyocyte differentiation. @*Conclusions@#These results provide a novel insight into the potential effect of p53 on the development and differentiation of cardiomyocyte during embryogenesis.

ABSTRACT

Objective:To observe the efficacy of conbercept in the treatment of different types of diabetic macular edema (DME).Methods:A retrospective clinical study. From March 2019 to March 2021, 136 eyes of 136 patients with DME diagnosed in Department of Ophthalmology of Xi'an No.3 Hospital were included in the study. Among them, there were 65 males and 71 females; the average age was 56.65±8.65 years. All patients underwent best corrected visual acuity (BCVA), optical coherence tomography (OCT) examination, and glycosylated hemoglobin level (HbA1c) examination. Early Treatment Diabetic Retinopathy Study visual acuity chart was used for BCVA examination, which was converted into the logarithmic minimum angle of resolution (logMAR) visual acuity during statistics. An OCT instrument was used to measure the central retinal thickness (CRT) of the macula. According to the characteristics of OCT, DME was divided into diffuse retinal thickening (DRT) type, cystoid macular edema (CME) type, serous retinal detachment (SRD) type, mixed type, and grouped accordingly, respectively, about 30, 38, 33, 35 eyes. There was no significant difference in age ( F=1.189), sex ratio ( χ2=1.331), and HbA1c level ( F=3.164) of the four groups of patients ( P>0.05). All eyes were treated with intravitreal injection of 10 mg/ml conbercept 0.05 ml (including conbercept 0.5 mg) once a month for 3 consecutive times, and then treated as needed after evaluation. BCVA and OCT examinations were performed 1, 3, and 6 months after treatment with the same equipment and methods as before treatment. The changes of BCVA and CRT before and after treatment were compared and observed. For measurement data subject to normal distribution, one-way analysis of variance was performed for comparison between groups; χ2 test was performed for comparison of count data. Results:Before treatment, the logMAR BCVA of the eyes in the DRT group, CME group, SRD group, and mixed group were 0.68±0.11, 0.69±0.15, 0.71±0.12, 0.73±0.14, and CRT was 631.4±50.7, 640.6±55.7, 652.3±63.4, 660.4±61.8 μm. Compared with before treatment, 1, 3, 6 months after treatment, DRT group (BCVA: t=8.139, 11.552, 11.672; CRT: t=16.163, 21.653, 25.855), CME group (BCVA: t=8.923, 9.995, 13.842; CRT: t=16.163, 21.653, 25.855), SRD type group (BCVA: t=5.171, 7.315, 6.051; CRT: t=9.099, 13.731, 21.306), mixed type group (BCVA: t=5.072, 6.939, 7.142; CRT: t=6.920, 15.352, 17.538) The BCVA of the affected eyes was significantly increased, and the CRT was significantly decreased, and the difference was statistically significant ( P<0.05). At 6 months after treatment, the differences in logMAR BCVA and CRT of the 4 groups of eyes were statistically significant ( χ2=58.478, 64.228; P<0.05). The average number of injections in the eyes of the DRT group, CME group, SRD group, and mixed group were 3.37±1.35, 3.68±1.38, 4.18±1.40, 4.13±1.50 times, respectively. Compared with the average number of injections in the eye, the difference was statistically significant ( χ2=9.139, P=0.028). Conclusions:Conbercept can effectively reduce CRT and increase BCVA in eyes with different types of DME. Compared with SRD type and mixed type, DRT and CME type eye are more effective in improving vision, CRT reduction degree is greater, and the number of injections is less.

ABSTRACT

Spinocerebellar ataxias (SCAs), formerly known as autosomal dominant cerebellar ataxia, are a group of hereditary heterogeneous neurodegenerative disease that contains many subtypes. Spinocerebellar ataxia type 23 (SCA23), one type of SCAs, is caused by mutant prodynorphin (PDYN) gene. A 22-year-old patient was diagnosed with sporadic SCA23 due to gene detection, with a novel identified mutation, PDYN c.647C>T (p.P216L). Located in the dynorphin A-coding-region of PDYN gene, the pathogenic mechanism of the mutation may be relevant to the pathological changes caused by the variant including neurological dysfunction and death of cells. Mild improvement with the patient has been witnessed after active balance and speaking exercise.

ABSTRACT

Objective:To summarize long-term outcome of sacral neuromodulation (SNM) for refractory interstitial cystitis/bladder pain syndrome (IC/BPS).Methods:Between January 2013 and October 2020, 28 patients with IC / BPS who received SNM in Beijing Chaoyang Hospital and Hebei Yanda Hospital were retrospectively analyzed. There were 5 males and 23 females, with median age 63.00 (47.50, 66.75) years old. The urgency score was 4 (3, 4) points, 24-hour micturition frequency was 26 (20.50, 32.50) times, nocturia was 9 (7, 12) times, single urine volume was 59.00 (41.25, 79.50) ml, VAS score was 9.0 (8.0, 9.0) points, O′Leary-Sant score was 31.00 (20.25, 33.00) points, and single maximum urine volume was 100.0 (80.0, 127.5) ml. The improvement of symptoms before operation, test period and last follow-up were compared.Results:The urgency score was 2 (1, 3), the 24-hour micturition frequency was 17.00 (15.00, 22.75), the frequency of nocturia was 5.5 (4.0, 7.0), the single urine volume was 87.50 (70.25, 110.00) ml, the VAS score was 4.0 (3.0, 6.0) and the O′Leary-Sant score was 20.00 (17.00, 23.00) in 28 patients during the test period, which were significantly improved compared with those before operation ( P < 0.05). There was no significant difference in the single maximum urine volume of 135.0 (102.5, 160.0) ml between the two groups ( P > 0.05). 28 patients received SNM Ⅱ permanent stimulator implantation. The median follow-up time was 29.5 (21.25, 61.75) months. Among the 28 patients, 3 patients underwent cystectomy and ileal conduit after removal of the complete SNM system due to the unsatisfied results. Twenty-five cases (89.3%) were still treated with SNM. Among them, 6 cases accepted combinative therapy of oral medicine (antihistamines, sodium pentose polysulfate, hormones, immunosuppressants, etc.). Two cases accepted combinative therapy of intravesical instillation, including heparin in one case and sodium hyaluronate in the other one. Three cases accepted combinative therapy of botulinum toxin injection.One case accepted combinative therapy of bladder augmentation. Two cases accepted combinative therapy of traditional Chinese medicine (TCM). One case accepted combinative therapy of oral medicine and TCM. The remaining 10 cases didn't accept any treatment. Among them, 3 cases were still treated with SNM even though they were not satisfied with the effect, including 1 case due to electrode displacement. At the last follow-up of 25 patients, the urgency score was 2 (1, 3), the 24-hour micturition frequency was 16.50 (13.00, 19.75), the frequency of nocturia was 5.5 (4.0, 9.0), the single urine volume was 105.0 (72.5, 120.0) ml, the VAS score was 4.5 (3.0, 6.0) and the O'Leary Sant score was 16.00 (14.00, 22.50), which were significantly improved compared with those before operation ( P < 0.05), but no difference with those during test period ( P>0.05). There was no significant difference in the single maximum urine volume of 125.0 (102.5, 150.0) ml at the last follow-up compared with preoperative and test period ( P>0.05). Conclusions:As a treatment option for refractory IC / BPS, SNM can improve the symptoms of most patients and maintain good long-term efficacy combined with other.

ABSTRACT

Objective:We compare the consistency, similarities and differences of operating procedures, data and conclusions of air-charged catheters(ACC) and water-filled catheters(WFC), as simultaneously using ACC and WFC in pressure-flow study(PFS).Methods:This study was a prospective, synchronously controlled study, including eligible patients who underwent PFS in the Department of Urology, Beijing Chaoyang Hospital from January 2021 to March 2021. Inclusion criteria: ① Patients need PFS for lower urinary tract symptoms like frequency of urination, urgent urination, urinary incontinence and dysuria; ② Age over 18 years old. Exclusion criteria: ① Unable to complete or cooperate during the urodynamic test; ② Patients with severe urethral stricture or acute stage urinary tract infection; ③ Pregnant women. The bladder pressure was measured continuously by using a 7FDR T-DOC ?AC three-chamber bladder pressure tube, which linked to ACC sensor and improved WFC pressure conduction module. At the same time, 7FA T-DOC ?AC single-lumen rectal pressure tube and 7F Labori-CAT411 double-lumen water sac abdominal pressure tube was used to measure the ACC and WFC rectum pressure, respectively. We recorded the Pdet, Pves and Pabd measured by ACC and WFC, at the point of initial sitting position, bladder filling at 100 ml, 150 ml, 200 ml, cough, Q max, maximum Pdet and the end of urination, and compared the mean values, differences, and consistencies of our data. Result:A total of 63 patients (26 female, 37 male) were included in this study, with an average age of 59.19 years (25-86 years old). During bladder filling phase, the mean values of Pves measured by ACC and WFC were 30.78/24.67cmH 2O (initial sitting position), 29.79/25.13cmH 2O (100 ml), 30.87/25.90cmH 2O (150 ml) and 30.95/26.17cmH 2O(200 ml), respectively, the mean value of Pabd were 30.03/24.17cmH 2O (initial sitting position), 28.81/21.78cmH 2O (100ml), 28.89/21.38cmH 2O (150ml), 28.44/21.60cmH 2O (200ml), respectively, and were significantly different at each sampling point ( P<0.01). During urination period, no significant differences were found in data( P>0.05), and the data measured with ACC and WFC system have good consistency. There were significant differences in Pves(mean 57.30/49.95 cmH 2O, respectively) and Pdet(mean 54.21/43.10 cmH 2O, respectively) between ACC and WFC in cough ( P<0.01), but there was a strong linear correlation between these data between two systems(R 2=0.792 in Pves and 0.756 in Pabd). Bland-Altman analysis showed that detrusor pressure at the maximum urine flow rate maintained good consistency between ACC and WFC, which 95% CI was -13.9 cmH 2O to 15.8 cmH 2O. Conclusions:In PFS, although the ACC measurement values (Pves and Pabd) during the filling phase are higher than those WFC readings, but the absolute measurement difference is small, so there is no practical meaning in clinical practice. There was no significant difference in detrusor pressure measured during voiding phase, which indicated that the urodynamic judgment and clinical conclusions of the two systems are highly consistent in judgment of the detrusor contractility and the bladder outlet obstruction.
