Endometriosis is a common chronic gynecological disease with endometrial cell implantation outside the uterus.Angiogenesis is a major pathophysiology in endometriosis.Our previous studies have demon-strated that the prodrug of epigallocatechin gallate(ProEGCG)exhibits superior anti-endometriotic and anti-angiogenic effects compared to epigallocatechin gallate(EGCG).However,their direct binding targets and underlying mechanisms for the differential effects remain unknown.In this study,we demonstrated that oral ProEGCG can be effective in preventing and treating endometriosis.Additionally,1D and 2D Proteome Integral Solubility Alteration assay-based chemical proteomics identified metadherin(MTDH)and PX domain containing serine/threonine kinase-like(PXK)as novel binding targets of EGCG and ProEGCG,respectively.Computational simulation and BioLayer interferometry were used to confirm their binding affinity.Our results showed that MTDH-EGCG inhibited protein kinase B(Akt)-mediated angiogenesis,while PXK-ProEGCG inhibited epidermal growth factor(EGF)-mediated angiogenesis via the EGF/hypoxia-inducible factor(HIF-1a)/vascular endothelial growth factor(VEGF)pathway.In vitro and in vivo knockdown assays and microvascular network imaging further confirmed the involvement of these signaling pathways.Moreover,our study demonstrated that ProEGCG has superior therapeutic effects than EGCG by targeting distinct signal transduction pathways and may act as a novel anti-angiogenic therapy for endometriosis.

Objective: To compare the dwelling time and complications of low lying umbilical venous catheterization (UVC) in preterm infants with that of central UVC. Methods: This was a prospective cohort study. A total of 3 020 preterm infants from 44 neonatal intensive care units (NICU) who had UVC inserted from October 2019 to August 2021 were enrolled. Demographic and general baseline data, dwelling time of UVC and reasons for removal, complications and their occurrence time were collected. According to the position of the catheter tip, the preterm infants were divided into low lying UVC group (insertion depth of 3-5 cm) and central UVC group (the catheter tip was close to the entrance of right atrium, or at the 8th-9th thoracic vertebra level). The Mann-Whitney U test was used to compare the dwelling time and incidence of complications (cases/1 000 catheter days), and the independent t test and Chi-square test were used to compare the characteristics between the 2 groups. The receiver operating characteristic (ROC) curve was used to analyze the optimal cut-off value of UVC dwelling time. Results: Among the included 3 020 preterm infants, 1 624 (53.8%) were males, the gestational age was 29.9 (28.4, 31.6) weeks, the birth weight was (1 264±301) g, and 2 172 (71.9%) premature babies had central UVC. There were no significant differences in the proportion of males, the gestational age and the birth weight of neonates between the 2 groups (all P>0.05). There were also no significant differences in the rate of maternal history, PPROM>18 hours, chorioamnionitis, antenatal antibacterial angents exposure and antibacterial angents usage through UVC (all P>0.05). The dwelling time of central UVC was longer than that of low lying UVC (7 (6, 10) vs. 4 (3, 7) days, U=23.42, P<0.001). The complication incidence of central and low lying UVC were 20.0 and 70.8 cases/1 000 catheter days, respectively. The top 3 complications of central UVC were occlusion, catheter tip migration, and CLABSI (9.3, 3.5, 3.0 cases/1 000 catheter days). The top 3 complications of low lying UVC were catheter occlusion, CLABSI, and catheter tip migration (45.8, 6.3, 5.4 cases/1 000 catheter days). The ROC curve of UVC dwelling time and complications showed that the cut-off values of central UVC and low lying UVC were 6.5 and 4.5 days, respectively. The 2 groups both showed a trend of increases in the 3 complications with the prolonged dwelling time. Cox regression analysis showed that the overall difference in the proportion of occlusion between the central UVC and low lying UVC groups was statistically significant (χ2=30.18, P=0.024). There were both no significant differences in catheter tip migration and CLABSI (both P>0.05). Conclusions: The most common UVC complication in preterm infants is occlusion. It is not recommended to keep a low lying UVC for longer than 4.5 days. During the whole dwelling period, a close monitoring for UVC complications is required.

Aristolochic acid (AA), extracted from Aristolochiaceae plants, plays an essential role in traditional herbal medicines and is used for different diseases. However, AA has been found to be nephrotoxic and is known to cause aristolochic acid nephropathy (AAN).AA-induced acute kidney injury (AKI) is a syndrome in AAN with a high morbidity that manifests mitochondrial damage as a key part of its pathological progression. Melatonin primarily serves as a mitochondria-targeted antioxidant. However, its mitochondrial protective role in AA-induced AKI is barely reported. In this study, mice were administrated 2.5 mg/kg AA to induce AKI. Melatonin reduced the increase in Upro and Scr and attenuated the necrosis and atrophy of renal proximal tubules in mice exposed to AA. Melatonin suppressed ROS generation, MDA levels and iNOS expression and increased SOD activities in vivo and in vitro. Intriguingly, the in vivo study revealed that melatonin decreased mitochondrial fragmentation in renal proximal tubular cells and increased ATP levels in kidney tissues in response to AA. In vitro, melatonin restored the mitochondrial membrane potential (MMP) in NRK-52E and HK-2 cells and led to an elevation in ATP levels. Confocal immunofluorescence data showed that puncta containing Mito-tracker and GFP-LC3A/B were reduced, thereby impeding the mitophagy of tubular epithelial cells. Furthermore, melatonin decreased LC3A/B-II expression and increased p62 expression. The apoptosis of tubular epithelial cells induced by AA was decreased. Therefore, our findings revealed that melatonin could prevent AA-induced AKI by attenuating mitochondrial damage, which may provide a potential therapeutic method for renal AA toxicity.

Objective:To study the clinical characteristics, diagnostic methods and genotypes of neonatal chronic granulomatous disease(CGD).Methods:From April 2013 to August 2020, neonates admitted to our hospital, diagnosed with neonatal CGD and confirmed using neutrophil respiratory burst test and genetic testing were retrospectively studied. Their clinical characteristics and diagnostic methods were summarized.Results:A total of eleven neonates with CGD were enrolled, including ten males and one female. The age of onset was 3-23 d and the age of admission was 11-28 d. 3 cases had family history. The initial symptoms were fever (10 cases) and coughing (1 case). The accompanying symptoms included coughing (6 cases), dyspnea (4 cases), skin pustules (3 cases), fever (1 case) and diarrhea (1 case). Lung CT showed patchy shadows (6 cases), pulmonary nodules (3 cases), round and irregular high-density shadow (1 case), pulmonary consolidation (1 case), pleural effusion (1 case) and pleural thickening (2 cases). CGD was pathologically diagnosed in one patient. Sputum culture showed Candida albicans (3 cases), Aspergillus fumigatum (2 cases), Aspergillus fumigatum combined with Klebsiella pneumoniae and Escherichia coli (1 case), Aspergillus fumigatum combined with Staphylococcus aureus (1 case). GM tests were positive in two cases and negative in other two cases. Blood and cerebrospinal fluid cultures were negative. White blood cell counts were (10.0-44.0)×10 9/L and C-reactive proteins were (14-165) mg/L. 11 cases had positive neutrophil respiratory burst test. Genetic tests showed CYBB gene mutations (9 cases) , NCF1 gene mutation(1 case) and NCF2 gene mutation (1 case). All cases received antibacterial and antifungal treatments for 2-5 weeks and were discharged with improvement. 8 patients survived, 5 received hematopoietic stem cell transplantation, 4 succeeded and one failed and continued to survive on oral medication. 3 cases took sulfamethoxazole, voriconazole or itraconazole orally for long periods. 3 cases died of severe infections after withdrawal of medication. Conclusions:Neonatal CGD is characterized by lung infections. Pulmonary CT shows mostly nodular or patchy shadows with occasional pulmonary consolidation or pleural effusion. It can be diagnosed by neutrophil respiratory burst test and genetic testing. X-linked CYBB gene mutations are common and autosomal recessive NCF1/NCF2 gene mutations less common.

Objective:To evaluate the efficacy and safety of umbilical venous catheterization (UVC) by using different methods to estimate the insertion depth.Methods:PubMed, Embase and The Cochrane Library, CBM (SinoMed), CNKI, VIP Database, Wanfang Database and Chinese Medical Journal Full-text Database were electronically searched for literature on randomized controlled trials (RCTs) comparing different methods for estimating the insertion depth of UVC. The search period was from the establishment date of the above databases to April 15th, 2022. If 2 or more studies were available for each pairwise comparison, a meta-analysis was conducted using the RevMan 5.3 software. However, if only 1 study was included for each pairwise comparison, SPSS 26.0 statistical software is used for statistical analysis using the chi-square test.Results:A total of 9 RCTs were included in the final meta-analysis, with a total of 1 281 infants, using 6 methods for estimating the depth of UVC. Compared with the Shukla formula, the Dunn method showed a statistically significant improvement in the correct place rate at the first UVC attempt ( RR=1.27, 95% CI 1.09-1.47, P=0.002). When comparing the Dunn method with the revised Shukla formula, the difference in the correct place rate at the first UVC attempt was statistically significant (21.4% vs. 33.5%, χ2=7.24, P=0.007). There was no statistically significant difference in the correct place rate at the first UVC attempt between the Dunn method and the formula based on BW, the JSS formula and the revised Shukla formula, and the method based on anatomical marks and the Shukla formula. There was no statistically significant difference in the incidence of UVC complications between the Dunn method and the Shukla formula, and between the method based on anatomical marks and the Shukla formula. Conclusions:Comparing to Shukla formula, Dunn method has a higher correct place rate at the first attempt. The incidence of complications is similar between the different pairwise comparison methods.

Objective:To systematically evaluate the safety of family integrated care (FICare) model in neonatal intensive care unit (NICU).Methods:Multiple medical databases were searched for clinical studies on FICare in NICU published from January 1, 2010 to May 28, 2022. The quality of the literature was evaluated using Risk?of?Bias?2 tool?and cohort evaluation criteria from the Cochrane Systematic Evaluation Manual depending on the types of studies included. Meta-analysis was performed using Review Manager 5.3 software.Results:Six randomized controlled trials and four cohort studies were included for meta-analysis. The results of meta-analysis showed that compared with the traditional care model, FICare model did not increase the risk of nosocomial infection ( RR=0.75, 95% CI 0.46-1.24, P=0.27) and unstable medical conditions ( RR=0.86, 95% CI 0.61-1.22, P=0.40). No significant difference existed in the all-cause mortality between FICare and traditional care ( RR=2.74, 95% CI 0.88-8.57, P=0.08). Conclusions:FICare does not increase the risk of nosocomial infection, unstable medical conditions and adverse events compared with traditional care. It is safe and feasible to implement FICare in NICU.

Objective@#To investigate the level of arsenic exposure in rural drinking water and to assess the health risk caused by exposure to arsenic in Tongzhou District, Beijing Municipality in 2019, so as to provide insights into improving the quality of rural drinking water.@*Methods@#Water samples were collected from self-provided wells in 196 villages of 7 townships in Tongzhou District from April to June, 2019, and the arsenic levels were measured in drinking water according to Standard examination methods for drinking water-Metal parameters (GB/T 5750.6-2006). The carcinogenic and non-carcinogenic risks of arsenic were evaluated in drinking water using the environmental risk assessment model recommended by the United States Environmental Protection Agency (EPA).@*Results@#Totally 520 water samples were collected, and the median arsenic concentration was 0.001 2-0.050 0 mg/L. There were 67 water samples with arsenic levels exceeding the defined standard level (12.88%), and the proportions of arsenic levels exceeding the defined standard level were 57.69%, 17.24%, 12.20%, 6.52% and 1.31% in Songzhuang, Huoxian, Lucheng, Zhangjiawan and Yongdedian townships, and the arsenic levels did not exceed the defined standard level in Majuqiao or Taihu townships. The carcinogenic risk of arsenic was 3.135 7×10-4/a in drinking water, which exceeded the maximum acceptable risk, and the carcinogenic risk of arsenic all exceeded the maximum acceptable risk, with the highest value seen in Songzhuang Township (9.648 2×10-4/a). A high carcinogenic risk of arsenic was seen in men at ages of 60 to 80 years (3.012 8×10-4/a) and in women at ages of 80 years and older (2.949 0×10-4/a). The non-carcinogenic risk of arsenic was 0.696 8 in drinking water, indicating a low risk, and were 1.009 5 and 2.144 1 in Huoxian and Songzhuang townships, indicating a high risk. In addition, a high non-carcinogenic risk of arsenic was seen in men at ages of 60 to 80 years (0.669 5) and in women at ages of 80 years and older (0.655 3).@*Conclusion@#There was a high proportion of arsenic levels exceeding the defined standard level in rural drinking water in Tongzhou District, 2019, and there was a health risk, notably with the highest carcinogenic risk seen in residents at ages of 60 years and older. Effective interventions are needed to reduce arsenic levels in drinking water.

Objective:To study the clinical features and prognosis of infantile hepatic hemangioendothelioma-arteriovenous fistula (IHHE-AVF) complicated with heart failure in neonates.Method:From May 2016 to June 2020, neonates with IHHE-AVF complicated with heart failure admitted were retrospectively studied. The clinical presentation, treatment and outcomes were analyzed.Result:A total of 11 cases of IHHE-AVF complicated with heart failure were enrolled (male 5, female 6). The onset age of heart failure was 12.0 (0.0, 17.0) d. 6 cases showed IHHE on fetal ultrasound. All patients had significantly enlarged heart on chest X-ray. All patients had decreased left ventricular systolic function and pulmonary hypertension on echocardiography. All patients required respiratory support and 6 of them were intubated. 3 cases received conservative treatment (all dead). 1 case received surgery (dead). 7 cases received interventional therapy at the age of (25.6±18.5) d. 1 case was dead, and the other 6 cases were improved and discharged. All the 6 cases were followed up to 3~18 months. None of them had heart failure again. The IHHE were shrunk or completely disappeared. Coagulation function and platelet count were normal.Conclusion:The fatality rate of neonatal-onset IHHE-AVF complicated with heart failure is extremely high. Interventional therapy may be more effective than conservative therapy and surgery.

Umbilical venous catheterization (UVC) is associated with many complications, such as displacement of the catheter, infection, exudation, thrombosis, pericardial effusion/pleural effusion, of which central line-associated bloodstream infections has been of long-standing interest. There is currently no optimal method for estimating the depth of UVC insertion. Ultrasound examination can be used to evaluate the position of the end of the tube after catheterization to avoid organ damage and complications caused by displacement and dislocation. However, whilst it is known that there is a correlation between the duration of UVC and central line-associated bloodstream infection, a consensus is yet to be reached regarding the optimal duration of UVC retention. More, high quality evidence through multi-center, prospective randomized controlled study is needed.

Objective:To explore the clinical manifestations, genetic disorder, prognosis of 14 neonates with primary immunodeficiency disease(PID).Methods:A total of 14 newborns with PID admitted to Department of Neonatology at Beijing Children′s Hospital from January 2017 to December 2019 were enrolled for retrospective analysis, focusing on their clinical manifestation, peripheral blood cell examnations, gene mutation, and outcomes after hemotopoietic stem cell transplantation(HSCT).Results:The average gestational age of the newborn was (38.6±1.2) weeks, the birth weight was (3 265±325)g, and the median diagnosis time was 57.5 days.Fourteen newborns with PID were diagnosed by whole exome sequencing as chronic granuloma (6/14), DiGeogre syndrome (3/14), Wiskott-Aldrich syndrome (2/14), severe combined immunodeficiency (2/14) and selective IgA deficiency (1/14). Regarding the clinical manifestations, fever, pneumounia and colitis accounted for 7/14, the decrease of T lymphocytes in peripheral blood accounted for 6/14, and the decrease of B lymphocytes accounted for 5/14.The absolute value of eosinophils increased (>500 cells/mm 3) accounted for 12/14, of which moderately increased (1 500 to 5 000 cells/mm 3) accounted for 5/12, and the absolute value of monocytes increased (median>1.5×10 9/L) accounted for 7/14.Follow-up children received HSCT accounted for 7/14, and the median time of receiving transplantation was 330 days after birth.By the time of follow-up, the primary disease resolved after HSCT accounted for 5/7, and the survival rate was 85.7%.Among them, two children with chronic granulomatosis were diagnosed with inflammatory bowel disease before transplantation, and the primary disease improved after HSCT.Three-quarters of the deaths had inflammatory bowel disease-like manifestations and died of infectious shock. Conclusion:The clinical manifestations of children with PID during the neonatal period are not specific.The manifestations of colitis need more attention.Some of the newborns with PID will evolve into inflammatory bowel disease or have inflammatory bowel disease-like manifestations or even die of it.HSCT is a fundamental treatment for the primary disease.

Objective: To investigate the safety and efficacy of ultrafiltration on diuretic sensitivity in heart failure patients with reduced ejection fraction and diuretic resistance. Methods: This was a single-center randomized controlled trial. A total of 148 heart failure patients with reduced ejection fraction admitted to the Hospital of Traditional Chinese Medicine of Xinjiang Uygur Autonomous Region from June 2010 to June 2020 were enrolled in this study, and these patients were randomly divided (ratio 1:1) into the ultrafiltration group (n=74) and the control group (n=74). All patients were treated with diuretics, cardiotonic, vasodilator and other comprehensive drugs according to relevant guidelines. After grouping, the patients in the control group were treated with standard treatment plan, while patients in the ultrafiltration group were treated with ultrafiltration on top of standard therapy. Diuretic drugs were discontinued during ultrafiltration, and intravenously furosemide (40 mg) was given immediately and 24 hours after the end of ultrafiltration. Clinical data including gender, age, complicated diseases, New York Heart Association (NYHA) function classification, etc. were collected. Effectiveness indicators include urine volume (the first 12-hour and 24-hour urine volume and the second 24-hour urine volume after using diuretic), body weight and dyspnea severity score. Safety indicators include systolic blood pressure, serum creatinine, serum Na+ concentration, blood K+ concentration and the number of deaths before and after intervention. Results: Two patients in the control group died due to worsening heart failure after randomization and were excluded in this study, 146 patients were finally analyzed (72 patients in the control group and 74 patients in the ultrafiltration group). There were 93 males, and the age was (68.3±11.2) years. There was no significant difference between patients in the ultrafiltration group and the control group in gender, age, body weight, course of disease, dyspnea severity score, NYHA function classification Ⅲ/Ⅳ, the proportion of patients with severe edema of both lower limbs, the proportion of patients with complicated diseases, and basic medication (all P>0.05). After using diuretics, the urine volume of the first 12-hour and 24-hour and the second 24-hour were significantly higher in the ultrafiltration group than in the control group (all P<0.05). Body weight decreased significantly after ultrafiltration treatment as compared with that before intervention in the ultrafiltration group (P<0.05). Compared with the control group, the dyspnea severity score was significantly improved in the ultrafiltration group (P<0.05). There was no significant difference in systolic blood pressure, serum creatinine, serum Na+ concentration, blood K+ concentration of patients between ultrafiltration group and control group before and after intervention (all P>0.05). During the clinical diagnosis and treatment, 2 male patients in the control group died, and the cause of death was aggravation of basic diseases complicated with acute heart failure and cardiogenic shock. There was no death in the ultrafiltration group, and there were no obvious clinical adverse events during and after ultrafiltration. Conclusion: Ultrafiltration therapy is safe and can improve diuretic sensitivity in heart failure patients with reduced ejection fraction and diuretic resistance.

Objective:To analyze the diagnosis, treatment, and outcomes of neonates with deep venous thrombosis (DVT) of the extremities and torso.Methods:The clinical diagnosis, treatment and outcomes of seven neonates with DVT of the extremities and torso admitted to Beijing Children's Hospital, Capital Medical University from March 2016 to March 2020 were retrospectively analyzed. Paired t test and paired rank sum test were used to compare the difference of coagulation indexes before and after the anticoagulant therapy. Results:Among the seven neonates with DVT of the extremities and torso, six were male and five were term infants, with the gestational age of (37.9±2.5) weeks and birth weight of (2 989±619) g. The median age at admission was 2.0 d and the age at diagnosis was 3.0 d. Except for one case of left common femoral vein thrombosis with limb swelling on the affected side, the other cases were all found with DVT by routine abdominal ultrasound examination after admission. Six cases received heparin treatment with the median duration of 8.5 d (1.8-28.8 d), including four cases of thrombosis in the portal venous, one in the postcava and renal venous, and one in the left common femoral vein. Among the six cases, the thrombus disappeared in five cases, which were confirmed by vascular ultrasound examination during follow-up, and in another case, the thrombus was shrinked significantly but remained. After the treatment, the platelet count [(464.5±128.9)×10 9/L vs (142.5±104.2)×10 9/L, t=－5.019, P=0.004] and antithrombin-Ⅲ level [(67.08±28.87)% vs (46.05±12.60)%, Z=－2.201, P=0.028] were increased and the D-dimers was decreased [0.392 mg/L(0.250-0.884 mg/L) vs 2.511 mg/L(0.755-14.033 mg/L), Z=－2.201, P=0.028] with no reports of heparin-related side-effect. One case with advanced postcaval thrombosis did not receive heparin anticoagulant therapy, but the thrombosis disappeared 270 d after diagnosis during follow-up. Conclusions:DVT of the extremities and torso may have no specific symptoms during the neonatal period and the overall prognosis is good. Heparin anticoagulant therapy is recommended until thrombosis disappears for patients with large thrombosis or significantly high level of D-dimer. The course of heparin treatment varies greatly among individuals, and close monitoring is required.

OBJECTIVE@#To evaluate whether the efficacy of Getong Tongluo Capsule (, GTC, consisted of total flavone of Radix Puerariae) on improving patients' quality of life and lowering blood pressure are superior to the extract of Ginkgo biloba (EGB) for patients with convalescent-phase ischemic stroke and primary hypertension.@*METHODS@#This randomized, positive-drug- and placebo-controlled, double-blind trial was conducted from September 2015 to October 2017. Totally 477 eligible patients from 18 hospitals in China were randomly assigned in a 2:1:1 ratio to the following interventions, twice a day for 12 weeks: (1) GTC 250 mg plus EGB-matching placebo 40 mg (237 cases, GTC group), (2) EGB 40 mg plus GTC-matching placebo 250 mg (120 cases, EGB group) or (3) GTC-matching placebo 250 mg plus EGB-matching placebo 40 mg (120 cases, placebo group). Moreover, all patients were orally administered aspirin enteric-coated tablets 100 mg, once a day for 12 weeks. The primary outcome was the Barthel Index (BI). The secondary outcomes included the control rate of blood pressure and National Institutes of Health Stroke Scale (NIHSS) scores. The incidence and severity of adverse events (AEs) were calculated and assessed.@*RESULTS@#The BI relative independence rates, the clinical recovery rates of NIHSS, and the total effective rates of NIHSS in the GTC and EGB groups were significantly higher than the placebo group at 12 weeks after treatment (P0.05). The control rate of blood pressure in the GTC group was significantly higher than the EGB and placebo groups at 12, 18 and 24 weeks after treatment (P0.05).@*CONCLUSION@#GTC exhibited significant efficacy in improving patients' quality of life as well as neurological function and controlling hypertension.

ABSTRACT Background: The diagnostic value and suitability of prostate cancer antigen 3 (PCA3) for the detection of prostate cancer (PCa) have been inconsistent in previous studies. Thus, the aim of the present meta-analysis was performed to systematically evaluate the diagnostic value of PCA3 for PCa. Materials and Methods: A meta-analysis was performed to search relevant studies using online databases EMBASE, PubMed and Web of Science published until February 1st, 2019. Ultimately, 65 studies met the inclusion criteria for this meta-analysis with 8.139 cases and 14.116 controls. The sensitivity, specificity, positive likelihood ratios (LR+), negative likelihood ratios (LR−), and other measures of PCA3 were pooled and determined to evaluate the diagnostic rate of PCa by the random-effect model. Results: With PCA3, the pooled overall diagnostic sensitivity, specificity, LR+, LR−, and 95% confidence intervals (CIs) for predicting significant PCa were 0.68 (0.64-0.72), 0.72 (0.68-0.75), 2.41 (2.16-2.69), 0.44 (0.40-0.49), respectively. Besides, the summary diagnostic odds ratio (DOR) and 95% CIs for PCA3 was 5.44 (4.53-6.53). In addition, the area under summary receiver operating characteristic (sROC) curves and 95% CIs was 0.76 (0.72-0.79). The major design deficiencies of included studies were differential verification bias, and a lack of clear inclusion and exclusion criteria. Conclusions: The results of this meta-analysis suggested that PCA3 was a non-invasive method with the acceptable sensitivity and specificity in the diagnosis of PCa, to distinguish between patients and healthy individuals. To validate the potential applicability of PCA3 in the diagnosis of PCa, more rigorous studies were needed to confirm these conclusions.
