RESUMO
Objective: To analyze the clinical features of anti-neurofascin-155 (NF155) antibody positive autoimmune nodopathy in children. Methods: This was a case series study. A total of 6 children who were diagnosed accurately as anti-NF155 antibody positive autoimmune nodopathy by cell immunofluorescence assay at the Children's Hospital of Fudan University from January 2020 to December 2023 were collected. This study retrospectively analyzed 6 pediatric children's clinical manifestations, laboratory and electrophysiological examination results, and treatment outcomes. Results: Among 6 children with anti-NF155 antibody positive autoimmune nodopathy, there were 4 boys and 2 girls. The onset age of 6 children ranged from 3 years and 8 months to 12 years. All 6 children had extremity weakness (more severe in the distal and the lower extremities than in the upper extremities), 5 children had sensory deficits such as numbness or pain in the extremities, 4 children had tremors and ataxia, 3 children had cranial nerve involvement. Among the 6 children, 4 children had protein-cell separation in cerebrospinal fluid examinations. Among the 6 children, 1 child had central nervous system demyelination, the brain magnetic resonance imaging showed multiple abnormal signals in the bilateral cerebral hemispheres. Four children showed motor and sensory nerve damage in electrophysiological examination, and 2 children only showed motor nerve damage. Three children showed myelin and axonal damage, and 3 children only showed axonal damage. Among the 6 children, 5 children were treated with intravenous immunoglobulin and steroids. Among them, 2 children underwent plasma exchange due to poor efficacy, and subsequently, rituximab was added. There was 1 child changed the treatment with olfatomumab since the symptoms did not significantly improve after using rituximab. After treatment for 4-15 months, 2 children had no clinical symptoms, 1 child had improvement in clinical symptoms, 2 children had no significant improvement in clinical symptoms, and 1 child who did not receive the immunotherapy had no significant change in clinical symptoms. Conclusions: Anti-NF155 antibody positive autoimmune nodopathy in children presents with varying degrees of clinical manifestations. It is mainly characterized by extremity weakness, numbness and pain, often accompanied bytremorsand ataxia. Some pediatric patients may also have central nervous system demyelination. Cerebrospinal fluid and electrophysiological examination are important auxiliary examination methods. If steroid therapy is not effective, plasma exchange and rituximab treatment should be used as soon as possible.

With the extensive application of targeted drugs, the survival rate of cancer patients has been significantly improved. However, adverse reactions to the drugs have also become apparent, especially those affecting the ocular surface, which can severely impact patients' vision and quality of life. The article systematically analyzes a variety of targeted drugs, including epidermal growth factor receptor inhibitors, human epidermal growth factor receptor 2 inhibitors, fibroblast growth factor receptor inhibitors, selective estrogen receptor modulators, vascular endothelial growth factor receptor inhibitors, aromatase inhibitors, proteasome inhibitors, antibody-drug conjugates, Bruton's tyrosine kinase inhibitors, FMS-like tyrosine kinase 3 inhibitors, and cyclin-dependent kinase inhibitors, and discusses their adverse reactions on the ocular surface. The review emphasizes the role of clinicians in monitoring and managing patients' ocular surface health and the importance of early diagnosis and intervention to ensure that patients receive optimal visual protection while undergoing antitumor treatment.

Objective: To explore the value of predicting shunt-dependent hydrocephalus (SDHC) in patients with aneurysmal subarachnoid hemorrhage (aSAH) based on whole brain CT perfusion(CTP) and clinical data within 24 hours at admission. Methods: The clinical and imaging data of aSAH patients who received interventional embolization in our hospital were retrospectively collected from March 2018 to August 2022. All patients underwent one-stop whole brain CT examination within 24 hours after symptom onset, and the qualitative and quantitative CTP parameters were obtained after post-processing. Follow-up was conducted once every 2 months by consulting electronic medical records or by telephone for 6 months. According to whether SDHC occurred or not, the patients were divided into SDHC group and non-SDHC group. The differences between the two groups were compared. Logistic regression model was used to analyze and determine the predictive factors of SDHC, and the SDHC predictive model was established. The effectiveness of the predictive model was evaluated by drawing the receiver operating characteristic (ROC) curve of the subjects. Results: A total of 414 patients were included, including 132 males and 282 females, aged (59±11) years. 17.6%(73/414) patients had SDHC. There were significant differences in the occurrence of acute hydrocephalus, the World Neurosurgical League Scale (WFNS), the Hunt-Hess scale, the modified Fisher score (mFS), and the qualitative and quantitative parameters of CTP between the two groups (both P<0.001). Multivariate logistic regression analysis showed that acute hydrocephalus (OR=8.621, 95%CI: 4.237-17.542),old age (OR=1.107, 95%CI: 1.068-1.148), high mFS and high Hunt-Hess classification (OR=3.740, 95%CI: 1.352-10.342) were the risk factors of SDHC in aSAH patients, and high mean cerebral blood flow (mCBF) (OR=0.931, 95%CI: 0.885-0.980) was a protective factor of SDHC.The area under ROC curve (AUC) of the prediction model constructed by these five variables was 0.923(95%CI: 0.89-0.95), with 84.5% sensitivity and 87.7% specificity. Conclusion: The mCBF and acute hydrocephalus, age, mFS and Hunt-Hess classification within 24 hours at admission can be used to predict SDHC for aSAH patients.

Objective: To explore the clinical and biochemical discriminants of hyperandrogenism in functional hypothalamic amenorrhea (FHA). Methods: From January to September 2022, a total of 56 patients with FHA group in the Obstetrics and Gynecology Hospital of Fudan University outpatient clinic were included in this retrospective cross-sectional analysis. According to the clinical or biochemical features of hyperandrogenism, FHA patients can be divided into two subgroups, namely hyperandrogenic FHA and non-hyperandrogenic FHA. Explore the differences and its significances between hyperandrogenic FHA and non-hyperandrogenic FHA by comparing anthropometry, reproductive hormones, AMH, ultrasonic manifestation, the scores of eating attitude test, depression questionnaire and anxiety scale respectively and analyzing their correlations. Results: The age of 56 FHA patients was 15-32(23.36±4.90) years, and body mass index(BMI) was (18.91±2.49) kg/m2. The age of hyperandrogenic FHA and non-hyperandrogenic FHA was (21.76±4.40) and (24.05±5.00) (P=0.109) years old respectively, and BMI was (19.14±3.15 )and (18.81±2.18) kg/m2 (P=0.702). Compared to the non-hyperandrogenic FHA, the AMH (6.46 and 3.63 ng/ml, P=0.025) and PRL (278.78 and 149.46 mU/ml, P=0.002) levels were higher in hyperandrogenic FHA group. There was no significant difference between the hyperandrogenic and non-hyperandrogenic FHA group in body composition.GAD-7 (r=0.455, P=0.005) and PHQ-9 (r=0.664, P<0.001) were correlated with EAT-26 scores in non-hyperandrogenic FHA group, but no significant correlation was shown between PHQ-9 (r=0.091, P=0.766)ãGAD-7 (r=0.304, P=0.313) and EAT-26 in hyperandrogenic FHA group. Conclusions: Some patients with FHA had clinical manifestations of hyperandrogenism and mildly elevated AMH and PRL, with underlying PCOS endocrine characteristics.

The cornea is a transparent tissue with significant refractive and barrier functions. Corneal epithelium constitutes the first line of defense against foreign pathogens. Corneal epithelial cells interact to form a functionally selective permeability barrier. Dysfunction of this barrier leads to corneal impairment followed by a series of ocular surface diseases and even blindness. Tight junctions (TJ), located at the top of the intercellular space of corneal epithelial superficial cells, play a critical role in establishing and maintaining the barrier function. Previous studies have shown that destruction of the TJ acts as a crucial step of the occurrence and progression of multiple ocular surface diseases. Understanding the fundamental features and functions of the TJ, noticing the risk factors of TJ disruption, and clarifying the key role of TJ in the pathogenesis of various ocular surface diseases will help to better understand and treat ocular surface diseases.

Objective: To investigate the diagnosis, treatment and prognosis of ureteral endometriosis with hydronephrosis. Methods: A retrospective study was performed of 92 cases diagnosed as ureteral endometriosis with surgery confirmed in Peking University First Hospital from January 2000 to January 2021. Results: The incidence of ureteral endometriosis was 0.9% (92/10 222), with an average age of (40.0±6.0) years. Among 92 cases, urological symptoms and pelvic pain including dysmenorrheal, periodic abdominal pain were the main forms of clinical characteristics, while 11 patients (12%, 11/92) were asymptomatic. All patients with ureteral endometriosis had hydronephrosis and hydroureter before surgery, hydronephrosis were left sided in 48 (52%, 48/92) patients, right sided in 39 (42%, 39/92) patients, both sided in 5 (5%,5/92) patients. The distal and middle sections of ureteral obstructions existed in 73 (79%, 73/92) patients and 19 (21%, 19/92) patients, respectively. Out of the 92 ureteral lesions 71 (77%, 71/92) patients were extrinsic lesions, 21 (23%, 21/92) patients presented intrinsic lesions. Of the 38 cases who took preoperative radionuclide renal dynamic imaging examination, there were 6 (16%, 6/38) cases of mildly damaged, 7 (18%, 7/38) cases of moderately dameged, 14 (37%, 14/38) cases of severely damaged, and 11 (29%, 11/38) cases of normal renal function. Laparotomy was decided in 25 (27%, 25/92) patients, and laparoscopic surgery in 67 (73%, 67/92) patients. In cases of ureteral surgery, ureterolysis, partial ureteral resection and ureterocystoneostomy, partial ureteral resection and end-to-end ureteral anastomosis and nephroureterectomy were undertaken in 52 (57%, 52/92), 20 (22%, 20/92), 12 (13%, 12/92) and 8 (9%, 8/92) patients separately. The median follow up was 108 months (range: 6 to 240 months). During the follow-up period, 68 (87%, 68/78) patients took urinary ultrasound after surgery, and 60 (88%, 60/68) cases of hydronephrosis disappeared, and 8 (12%, 8/68) cases were better than before. Conclusion: Most of the patients with ureteral endometriosis are impaired with renal function, and early surgical treatment could effectively relieve urinary obstruction and promote the recovery of renal function.

Objective: To examine the clinical application effects of two-complex and one-plane technique for the renal artery dissected location in transperitoneal laparoscopic radical nephrectomy(LRN). Methods: Clinical data of patients diagnosed as renal tumor between January 2016 and December 2019 that treated with transperitoneal LRN and the two-complex and one-plane technique was performed to locate and dissect the renal arteries were analyzed retrospectively. A total of 206 qualified patients were enrolled, included 71 cases from Kaifeng Central Hospital and 135 cases from the First Affiliated Hospital of Zhengzhou University. There were 126 males and 80 females with median age of 54 years (range: 35 to 82 years). Renal tumor lived at left kidney in 102 cases and at the right in 104 cases, with a maximum tumor diameter of (6.8±2.5)cm (range: 3.0 to 12.7 cm). During the procession of transperitoneal LRN, The genital veins was followed to locate renal veins, soon the renal vein complex and renal lower pole complex and psoas major muscle plane that named as "two-complex and one-plane"anatomical markers were applied to the dissected location of renal arteries. The established application of two-complex and one-plane technique for renal artery location, and the anatomical features along with its locational time of renal artery, as well as vascular-related complications were recorded and analysed. The χ2 test or t test was used to compare the results of different lateral operations. Results: The surgical procedures were successful in all 206 patients. The operation time was (54.4±13.6) minutes (range:22 to 116 minutes), no injury to liver, spleen or intestine. Two-complex and one-plane technique was used to complete renal arteries location of 206 patients that accompanied with one or more arterial branch in the procession of transperitoneal LRN. Single renal artery branch was found in 163 cases, two or more renal artery branches were found in 43 cases, and 60 branches of accessory renal artery that in addition to the main trunks were detected in 14 cases (13.7%, 14/102) on left-side and 29 cases (27.9%, 29/104) on the right(χ²=6.251, P=0.012).The main branch of renal artery that directly been located inferior or posterior to renal vein in 165 cases, and the other 41 cases that born with higher-position of main branch been located through an upper"window-opening"of renal veins complex. Of the 60 accessory renal artery, 46 branch (76.6%, 46/60) been located inferior or posterior to renal veins, and the other 14 branch with higher-position (23.3%, 14/60) been located by a"window-opening"technique. The renal artery dissected location time was (21.2±9.4) minutes (range:11 to 43 minutes) in left-side and (17.5±9.3) minutes (range:9 to 32 minutes) in the right (t=2.840, P=0.005).The intraoprative bleeding was (51.8±25.2) ml (range:20 to 400 ml). There were 4 cases of vascular injury occured and treated with laporoscopy, only one need blood transfusion. Conclusions: The anatomical markers of renal vein complex and renal lower pole complex and psoas major muscle plane that can apply to locate various anatomical position types of renal artery in transperitoneal LRN effectively. The exactly application of two-complex and one-plane technique that could shorten the operational time of renal artery location and reduce the complications of vascular injury.

Objective: To investigate the present situation of unintended pregnancy within two years postpartum and its influencing factors in China. Methods: Participants who delivered a live birth at 60 hospitals in 15 provinces in the eastern, central and western regions of China during July 2015 to June 2016 were interviewed by using structured questionnaire. Information on occurrence of unintended pregnancy within 2 years after delivery, postpartum contraceptive use, sexual resumption, breastfeeding, and women's socio-demographic characteristics, and so on, were collected. Life-table analysis, cluster log-rank tests and a 2-level Cox regression model were used for data analysis. Results: A total of 18 045 postpartum women were investigated. The cumulative 1- and 2-year unintended pregnancy rates after delivery were 5.3% (95%CI: 4.5%ï¼6.1%) and 13.1% (95%CI: 11.3%ï¼14.8%), respectively. Cox regression model analysis showed that the risk of unintended pregnancy within 2 years postpartum were increased in younger women, ethnic minorities, women with abortion history, and those who had a vaginal delivery with short lactation time and late postpartum contraceptive initiation (all P<0.01). The risk of postpartum unintended pregnancy was not associated with geographic regions and hospitals where women gave a birth (all P>0.05). Conclusions: In China, the risk of unintended pregnancy within 2 years after delivery is relatively high. Service institutions and service providers should improve the quality of postpartum family planning services, promote the use of high effect contraceptive methods, and educate women to use a method at the time of their sexual resumption or even before.

OBJECTIVE: Coronary artery disease (CAD) is the main cause of mortality worldwide. How stable coronary artery disease (SCAD) progresses to acute myocardial infarction (AMI) is not known. This study was aimed to explore the differentially expressed genes (DEGs) and pathways involved in the progression of SCAD to AMI. MATERIALS AND METHODS: Publicly available gene-expression profiles (GSE71226, GSE97320, GSE66360) were downloaded from the Gene Expression Omnibus (GEO) database and integrated to identify DEGs. The GSE59867 dataset was further used to verify the result of screened DEGs. Functional-enrichment analyses, protein-protein interaction network, microRNA-transcription factor (TF)-mRNA regulatory network, and drug-gene network were visualized. RESULTS: Sixty common DEGs (CDEGs) were screened between the SCAD-Control group and AMI-Control group in the integrated dataset. Four upregulated DEGs were selected from GSE59867. Twenty hub genes were discovered, and three significant modules were constructed in the PPI network. The intersection of functional and pathway-enrichment analyses of 60 CDEGs and the module DEGs indicated that they were mainly involved in "inflammatory response", "immune response", and "cytokine-cytokine receptor interaction". A miRNA-TF-mRNA regulatory network comprised 87 miRNAs, 16 upregulated target DEGs and 7 TFs. CONCLUSIONS: We identified several important genes and miRNAs involved in the progression of SCAD to AMI: platelet activating factor receptor (PTAFR), aquaoporin-9 (AQP9), toll-like receptor-4 (TLR4), human constitutive androstane receptor-3 (HCAR3), leucine-rich-α2 glycoprotein-1 (LRG1), mothers Against Decapentaplegic Homolog 4 (SMAD4) and miRNA-149-5p, miRNA-6778-3p, and miRNA-520a-3p. Inflammation and the immune response had important roles in the progression from SCAD to AMI.

OBJECTIVE: Infective endocarditis (IE), particularly by Staphylococcus aureus, is an uncommon bacteremia-associated infection of the endocardium and cardiac valves. Herein, we evaluated predictive noninvasive biomarkers for IE caused by S. aureus through bioinformatics analysis. MATERIALS AND METHODS: Staphylococcus aureus-associated and IE-associated differentially expressed genes (DEGs) were identified by bioinformatics analysis of the GSE6269 and GSE29161 Gene Expression Omnibus (GEO) datasets. The DEGs were analyzed with the LIMMA package, and the coregulated genes were chosen as the intersection of DEGs between the two datasets, called common differentially expressed genes (CDEGs). The enrichment study of CDEGs was subsequently performed with the DAVID and KOBAS web resources. Finally, protein-protein interaction (PPI) network, microRNA (miRNA)-transcription factor (TF)-mRNA (messenger RNA) regulatory network, and the network of drug-genes were identified. RESULTS: From GSE6269 and GSE29161, respectively, a total of 201 and 741 DEGs were obtained. Gene Ontology (GO) analysis showed that CDEGs were primarily involved in innate immune response, extracellular exosome, as well as calcium ion binding, while the pathway analysis of Kyoto Encyclopedia of Genes and Genomes (KEGG) revealed that CDEGs were significantly enriched in the B-cell receptor, IL-17, and NF-kappa B signaling pathways. The hub genes in the PPI network included HP, S100A12, SPI1, CD14, CCR1, S100A9 and so on. In the miRNA-TF-mRNA regulatory network, SPI1 could target miR-361-5p, miR-155-5p, and miR-339-5p in the progression of IE. CONCLUSIONS: Several pivotal genes and pathways were identified in the progression of S. aureus-induced IE, which may have the potential for early detection.

Objective: To evaluate the influence of preoperative fasting duration on blood volume status of pediatric patients during induction based on ultrasonic technique. Methods: One hundred and ten pediatric patients, scheduled for elective operation in the Second Affiliated Hospital & Yuying Children's Hospital, were recruited during January and October in 2018. After sedation by inhalation of sevoflurane, the maximum (expiratory) and minimum (inspiratory) diameter of inferior vena cava (IVC(max), IVC(min)) and aorta velocity-time integral (VTI) in apical five-chamber cardiac view were measured with an ultrasound machine. Respiratory variabilities of these parameters were further calculated. Furthermore, passive leg raising (PLR) test was performed and above measurements/calculations were repeated. The correlation between the duration of fasting and IVC respiratory variations index (IVC(RVI)) or aortic VTI variability (ΔVTI) was then analyzed. Results: Before PLR, IVC(max), IVC(min) and IVC(RVI) were (0.78±0.19), (0.43±0.15) cm and 0.45±0.12, respectively. After PLR, IVC(max) and IVC(min) increased to (0.94±0.20), (0.55±0.18) cm, while IVC(RVI) decreased to 0.42±0.13, the differences were statistically significant (t=15.66, 10.85, 3.14, all P<0.05). However, IVC(max), IVC(min) and IVC(RVI) were not significantly correlated with the duration of fasting analyzed by linear regression (before PLR: r=0.052, 0.163, 0.171; after PLR, r=0.062, 0.169, 0.165, all P>0.05). Before PLR, expiratory aortic VTI (VTI(max)), inspiratory aortic VTI (VTI(min)) and ΔVTI were 21±5, 17±4 and 17±8, respectively. After PLR, the VTI(max) and VTI(min) significantly increased to 23±5 and 19±4 (t=13.60, 10.43, all P<0.05), but ΔVTI was not changed significantly, which was 17±8(t=0.34, P>0.05). Linear regression analysis showed that VTI(max), VTI(min) and ΔVTI were not significantly correlated with the duration of fasting (before PLR: r=0.111, 0.100, 0.047; after PLR: r=0.003, 0.033, 0.073, all P>0.05). Further multiple linear regression analysis indicated that, age and body weight were independent factors influencing IVC(RVI) and ΔVTI before and after PLR (IVC(RVI): ß=-0.441, 0.515, -0.451, 0.507; ΔVTI: ß=-0.442, 0.545, -2.422, 2.850; all P<0.05). However, the duration of fasting was not correlated with IVC(RVI) and ΔVTI after adjusting the age and weight (IVC(RVI): ß=0.177, 0.160; ΔVTI: ß=0.037, 0.054; all P>0.05). Conclusion: Age and weight, but not preoperative fasting duration, are correlated with respiratory variabilities of inferior vena cava diameter and aortic VTI in pediatric patients.

Objective: To measure the coagulation function of patients with adenomyosis so as to explore its relationship with increased menstrual amount and its clinical significance. Methods: From January 2014 to May 2019, clinical data of patients with hysterectomy in which 111 pathologically diagnosed adenomyosis (case group) and 115 with uterine myoma (control group) in Peking University First Hospital were retrospectively analyzed. The changes in coagulation function of the two groups were compared, and the correlation between coagulation and uterine volume in the adenomyosis group was analyzed. Results: (1) The activated partial thromboplastin time (APTT) was longer in the adenomyosis group than that in the uterine myoma group [(30.4±3.1), (29.6±2.5) s, respectively; P<0.05], while the thrombin time (TT) was shorter than that in the control group [(14.2±1.2), (14.6±1.0) s, respectively; P<0.05]. (2) According to the results of the Pearson correlation test, there was a positive correlation between prothrombin time (PT; r=0.135, P=0.042) and fibrinogen (FIB-C; r=0.139, P=0.036). (3) Platelet counts were higher in the anemia group of adenomyosis than that in the non-anemia group [(323±79)×109/L, (274±56)×109/L, respectively; P<0.05]. (4) FIB-C in non-anemia group of adenomyosis was lower than non-anemia group of uterine myoma [(2.8±0.5), (3.0±0.6) g/L, respectively; P<0.05], the anemia group of adenomyosis shortened TT compared with the anemia group of uterine myoma [(14.4±1.2), (15.2±0.9) s, respectively; P<0.05]. Conclusion: Patients with adenomyosis have abnormal coagulation function, which may be related to the increase amount of menstruation, and anemia may also be involved in coagulation disorders.

Objective: To further understand the current status of diagnosis and treatment of endometriosis in China, the implementation of guideline in different levels of hospitals, and the need for continuing education in endometriosis among primary doctors. Methods: The survey was conducted in the form of convenience sampling questionnaire among the Wechat public platform. The doctors were free to participate in the investigation without any reward. All questions answered were assessed as valid questionnaire. The datas were collected on the questionnaire network platform and analyzed by SPSS 19.0. Results: Totally 1 494 valid questionnaires were collected in this survey. 60.17% (899/1 494) of them were from tertiary hospital, and 32.60% (487/1 494) were from grade two hospital. Only the hospitals where 9.97% (149/1 494) participants based opened the specialist clinic for endometriosis. 70.35% (1 051/1 494) of participants said they had read the second edition of guideline for the diagnosis and treatment of endometriosis which published in 2015. The American Society for Reproductive Medicine (ASRM) staging system was adopted in the clinical practices of only 25.03% (374/1 494) participants. And 18.74% (280/1 494) participants used the endometriosis fertility index (EFI) scoring during the laparoscopic surgery for endometriosis with infertility. 45.18% (675/1 494) of participants said they had not attended any academic conference on endometriosis in the past six months. 64.46% (963/1 494) of the participants believed their diagnosis and treatment in practice should be improved and standardized. 87.15% (1 302/1 494) of the participants expressed the hope that more conferences or workshops on endometriosis would be held. Conclusions: At presents, the diagnosis and treatment of endometriosis in China has been greatly improved, but the implementation of guidelines and the new concept is still a long-term job. The specialist clinic are held only in a few hospitals. It's the expectation and voice of primary doctors to the association to organize the more academic congresses on endometriosis.
