ABSTRACT
Objective:To examine the clinicopathological and molecular pathological characteristics of patients with colorectal cancer(CRC)who have mutations in the POLE and POLD1 genes.Methods:In this study, we retrospectively collected data from 276 middle-aged and elderly patients aged 45 years and over who were diagnosed with colorectal cancer at Beijing Hospital between October 2020 and September 2022.We utilized next generation sequencing and bioinformatics analysis to screen for harmful germline and somatic mutations in the POLE and POLD1 genes.The study involved 276 patients, who were divided into three groups based on their genetic mutations.The deleterious mutation group had 6 cases, the mutation of unknown significance group had 18 cases, and the wild type group had 252 cases.We also collected clinical and pathological features of the patients and analyzed their correlation with other molecular pathological results such as tumor mutation burden(TMB), microsatellite instability(MSI), and gene co-mutation.Results:No germline mutations were detected in the POLE and POLD1 genes across all patients.Out of the 276 patients, 18(6.5%)were found to carry POLE mutations.Among these, 6(2.2%)were classified as deleterious mutations, 12(4.3%)were positive for POLE mutations of unknown significance, and the remaining patients had wild type POLE genes.Out of the 276 patients, POLD1 gene mutations of unknown significance were found in 10 patients(3.6%). Among the 276 patients, 5 cases(1.8%)carried two types of gene mutations.Patients in the deleterious mutation group showed earlier tumor stage( P<0.05)and a higher prevalence of low-grade tumor budding( P<0.05), with 6 patients being affected by this.Compared to the wild type group, colon cancer patients showed a higher frequency of deleterious mutations and variants of unknown significance in the poorly differentiated group( P<0.05). The median TMB in the deleterious mutation group was 257.76 muts/Mb, 74.4 muts/Mb in the mutation of unknown significance group, and 5.81 muts/Mb in the wild type group.The study found significant differences in TMB-H status among the three groups, with all P-values less than 0.01.MSI-H status was detected in 1 case(16.7%, 1/6), 14 cases(77.8%, 14/18), and 18 cases(7.1%, 18/276)in the deleterious mutation group, variant of undetermined significance group, and wild type group, respectively.Notably, patients with variants of undetermined significance had a higher MSI-H status than patients with wild type and POLE deleterious mutations, with all P-values less than 0.01.The frequencies of co-mutations in KRAS, NRAS, BRAF, and PIK3CA were higher in the deleterious mutation group compared to the mutation of undetermined significance group and wild type group(all P<0.05). Conclusions:Colorectal cancer(CRC)patients with harmful mutations and variants of undetermined significance exhibit unique clinicopathological features.Patients with variants of undetermined significance are more likely to develop colon cancer, show poor differentiation, and have higher frequencies of TMB-H(tumor mutational burden)and MSI-H(microsatellite instability-high).
ABSTRACT
Objective:To study the long-term clinical effect of transvaginal mesh (TVM) and pelvic floor reconstruction with native tissue repair (NTR) in the treatment of advanced pelvic organ prolapse (POP).Methods:Totally 207 patients with advanced POP who were treated in Hunan Provincial Maternal and Child Health Care Hospital from Jan. 2016 to Sep. 2019 were enrolled. The patient′s pelvic organ prolapse quantification were all at degree Ⅲ or above, and they all complained for different degree of symptoms. They were divided into two groups according to the different surgical methods, TVM group and NTR group. In TVM group, the mesh was implanted through the vagina for pelvic floor reconstruction, while in NTR group, the traditional transvaginal hysterectomy combined with uterosacral ligament suspension and anterior and posterior wall repair, as well as perineal body repair were performed. The median follow-up time was 60 months, during the follow up time, 164 cases (79.2%, 164/207) had completed follow-up, including 76 cases in TVM group and 88 cases in NTR group. The perioperative data and complication rates of the two groups were compared, and the subjective and objective outcomes of the two groups at 1, 3 and 5 years were observed, respectively. The objective efficacy was evaluated by three composite criteria, namely: (1) the distance from the farthest end of the prolapse of the anterior and posterior wall of the vagina to the hymen is ≤0 cm, and the descending distance of the top is ≤1/2 of the total length of the vagina; (2) determine the disappearance of relevant POP symptoms according to “Do you often see or feel vaginal mass prolapse？”; (3) no further operation or pessary treatment was performed due to prolapse. If the above three criteria were met at the same time, the operation is successful; otherwise, it was recurrence. The subjective efficacy was evaluated by the pelvic floor distress inventory-short form 20 (PFDI-20) and pelvic floor impact questionnaire-short form 7 (PFIQ-7).Results:The median follow-up time of the two groups was 60 months (range: 41-82 months). Five years after the operation, the subjective and objective cure rates of TVM group were 89.5% (68/76) and 94.7% (72/76), respectively. The subjective and objective cure rates in NTR group were 80.7% (71/88) and 85.2% (75/88), respectively. There were significant differences in the subjective and objective cure rates between the two groups ( χ2=9.869, P=0.002; χ2=3.969, P=0.046). The recurrence rate of TVM group was 5.3% (4/76), and that of NTR group was 14.8% (13/88). There was a significant difference between the two groups ( P=0.046). The postoperative PFDI-20 and PFIQ-7 scores of the two groups were significantly lower than those before surgery, and there were significant differences of the two groups before and after surgery (all P<0.05). Postoperative mesh exposure in TVM group was 1.3% (1/76). Conclusions:The long-term outcomes between the two groups show that the subjective and objective outcomes of pelvic floor reconstruction in TVM group are significantly higher than those in NTR group, and the recurrence rate is significantly lower than that in NTR group. TVM has certain advantages in the treatment of advanced POP.
ABSTRACT
Objective:To study the correlation between the quartering of nerve root subsidence sign (NRS) and the cross-sectional area (CSA) of the narrow segment thecal sac in patients with lumbar spinal stenosis (LSS).Methods:The data of 203 LSS patients in the Fourth People′s Hospital of Hengshui from January 2020 to December 2021 were retrospectively analyzed. All patients underwent MRI cross sectional scanning. The patients were divided into positive type a group ( n=62), positive type b group ( n=32), positive type c group ( n=51), and negative group ( n=58) by NRS quartering method. The minimum CSA, median sagittal diameter (PAD), and lateral recess sagittal diameter of each group were compared. The correlation between NRS quartering classification and the minimum CSA and related indicators of lumbar spinal stenosis was analyzed. Results:The minimum CSA, PAD, and sagittal diameter of the lateral recess in the positive a group, positive b group, and positive c group were all smaller than those in the negative group, while the Visual Analogue Scale (VAS) score and Oswestry Disability Index (ODI) were higher than those in the negative group; The minimum CSA, PAD, and sagittal diameter of the lateral recess in the positive b type and positive c type groups were smaller than those in the positive a type group, while the VAS score and ODI index were higher than those in the positive a type group; The minimum CSA, PAD, and sagittal diameter of the lateral recess in the positive c type group were smaller than those in the positive b type group; The VAS score and ODI index were higher than those of the positive b type group; The differences were statistically significant (all P<0.05). 203 patients were divided into 54 normal cases, 58 mild stenosis cases, 49 moderate stenosis cases, and 42 severe stenosis cases based on the minimum CSA. The coincidence rate between negative NRS and minimal CSA diagnosis as normal was 94.44%(51/54), the coincidence rate between positive type a and minimal CSA diagnosis as mild stenosis was 84.48%(49/58), the coincidence rate between positive type b and minimal CSA diagnosis as moderate stenosis was 53.06%(26/49), and the coincidence rate between positive type c and minimal CSA diagnosis as severe stenosis was 90.48%(38/42). Using the kappa consistency test, the kappa value for quantitative diagnosis of minimum CSA stenosis in NRS and LSS patients was 0.743, indicating good consistency. The kappa values for quantitative diagnosis of NRS, sagittal diameter of lateral recess, and PAD stenosis were 0.271 and 0.335, with poor consistency. NRS typing was negatively correlated with CSA and PAD ( r=-0.723, -0.581, all P<0.001), and positively correlated with VAS score and ODI index ( r=0.473, 0.640, all P<0.001). Conclusions:The NRS quartering method has a good consistency in diagnosing the severity of LSS patients and the minimum CSA of stenosis segments, suggesting that the NRS quartering method can better reflect the degree of Spinal stenosis, which can not only be used as an auxiliary indicator for qualitative diagnosis of LSS, but also has a high value in quantitative diagnosis.

ABSTRACT
OBJECTIVE To develop an individualized medication list for elderly patients by evidence-based pharmacy method， and to support clinical decisions on rational use of METHODS Firstly， drugs with risk genetic information were screened out by systematically reviewing evidence-based pharmacy information. Secondly， researchers investigated the included drugs in lists from different data E- sources. Drugs included in three or more data sources and drugs proposed by the expert committee were then included in the medication list. Thirdly， for the drugs included in two data sources， researchers designed questionnaires to investigate the necessity of drug-related gene testing. According to the scoring results of the expert questionnaire， drugs with higher scores were included in the list. Data sources included real-world data （list of high frequency medication in hospitals， high frequency medication for elderly outpatients and inpatients in National Health Care Claims Data， drugs related to frequent medication errors and so on） and evidence-based pharmacy evidence （the websites of Clinical Pharmacogenomics Implementation Consortium， Dutch Pharmacogenetics Working Group， Food and Drug Administration and so on）. RESULTS The study obtain 68 drugs with risk genetic information which were included in three data sources. Combined with 23 drugs proposed by the expert committee， a list containing 74 drugs was preliminarily formed after de-duplication. A total of 37 drugs included in two databases with risk genetic information were scored through the questionnaire survey to form a supplementary list of 26 drugs. This is the final composition of the list of 100 drugs developed in this study. Among them， there are 43 drugs for the central nervous system， 15 drugs for the cardiovascular system， 12 anti-tumor drugs and so on. Twelve drugs were included in six or more data sources， which mainly consisted of drugs for digestive system， all proton pump inhibitors. CONCLUSION In this study， a list of 100 commonly used drugs which require individualized medication for the elderly was developed by evidence-based pharmacy method. The drug list will be updated in time as available evidence changes， and can provide guidance for rational use of medicines for elderly patients.
ABSTRACT
【Objective】 To observe the regulation of autonomic nerves in blood donors during blood donation by heart rate variability analysis and explore the possible mechanism of donation related vasovagal reaction. 【Methods】 Electrocardiogram (ECG) of 90 blood donors was monitored by Fontaine Ⅰlead during the whole process of blood donation, and the 5-min heart rate variation before, during and after blood donation was analyzed. 【Results】 During the whole process of blood donation, the sympathetic HRV index (LF nu) and the sympathetic and vagal balance ability index (LF/HF) increased, whereas the vagal nerve index (pNN50, RMSSD, HFnu) and heart rate variability index (SDNN, Total power) decreased. For baseline heart rate variability of different blood donors (first-time vs. repeated, male vs. female, 18-24 years old vs. ≥25 years old, <400 mL vs. 400 mL) before blood donation, the pNN50, RMSSD and Total power of 18-24 years old blood donors were higher, but other indicators showed no significant difference. There were differences in HRV indexes of different types of blood donors during blood donation compared with before blood donation. The decrease of pNN50 and HFnu and the increase of LF/HF were larger in experienced blood donors than in first-time blood donors. The decrease of RMSSD was larger in male blood donors than in female blood donors; the change of LF/HF was larger in blood donors aged≥25 years than in blood donors aged 18-24 years; other indicators had no significant difference. 【Conclusion】 Blood donation leads to reflex readjustment of the cardiac autonomic tone: the sympathetic nerve is excited while the vagal nerve is suppressed. The cardiac autonomic nerve function of first-time blood donors, female donors and low-age (18-24 years old) donors to blood donation stress is not fully regulated. Donation related vasovagal reaction may be related to the autonomic nerve regulation function of blood donors.
ABSTRACT
【Objective】 To explore the effect of online and offline collaborative and integrated mode (Internet + blood donation souvenirs), and develop diversified scientific ways of caring for voluntary blood donors in combination with the potential expectation of the target population, ao as to recruit and retain more blood donors. 【Methods】 A total of 4 000 blood donors from Yichang Central Blood Station from January 1 to June 30, 2022 were selected, and they could collect souvenirs from online and offline. The intelligent platform V9.5 of modern blood station management information system of Qiao Technology was used to classify the data of online and offline souvenir distribution, and digital intelligent comparison and analysis on age, occupation, education, type (first-time blood donors or repeat blood donors), region (main urban districts of Yichang and other counties and suburban districts) and gender were carried out. 【Results】 A total of 1 400 blood donors chose online souvenirs, who were mainly under 25 years old, students, female, college education or above, urban areas and regular donors; 2 600 chose offline souvenirs, who were mainly over 25 years old, male, junior college degree or below, occupations other than students (medical workers, educators, etc.), counties and suburban districts, and first-time blood donors. The collaborative and integrated mode of the two distribution methods were complementary and had a good incentive effect on blood donor recruitment. 【Conclusion】 The online and offline collaborative and integrated mode demonstrates a good effect and meets the needs of different population. Digital intelligence system is helpful to develop diversified and scientific ways of caring for voluntary blood donors, recruit and retain more blood donors, achieve high-quality development of blood collection and supply, therefore guarantee the increasing demand for clinical blood use.
ABSTRACT
Objective@#To explore the relationship between depression, anxiety, stress and food addiction among primary and secondary school students in Yixing City, so as to provide reference and suggestions for maintaining healthy eating behavior and psychological health intervention and promotion among primary and secondary school students in Yixing City.@*Methods@#From December 2022 to February 2023, a stratified cluster random sampling method was used to select 4 180 primary and secondary school students from four primary and secondary schools in Yixing City, Jiangsu Province. A questionnaire survey was conducted using the Depression Anxiety Stress Scale-21 (DASS-21) and related behavior questionnaires. The data was analyzed using χ 2 test, Wilcoxon, Kruskal Wallis H rank sum test, and binary Logistic regression.@*Results@#The prevalence of food addiction among primary and secondary school students in Yixing City was 0.98% (41 students), and there was no statistically significant difference in the comparison of food addiction, depression, anxiety, and stress scores among students of different genders and age groups ( Z/H = -1.34- 5.74, P >0.05). There was a positive correlation between food addiction and binge eating behavior, depression, anxiety, and stress symptoms ( r=0.14-0.23, P <0.01). The results of binary Logistic regression showed that anxiety ( OR=5.68, 95%CI =1.74- 18.55 ) and stress ( OR=5.41, 95%CI =2.20-13.32) were positively correlated with the occurrence of food addiction in primary and secondary school students ( P <0.01).@*Conclusions@#The risk of food addiction among primary and secondary school students with anxiety and stress symptoms is higher than that of the general population. Guidance and intervention on student mental health should cover the entire compulsory education and high school period, in order to improve the mental health level of students and reduce the occurrence of food addiction behavior.
ABSTRACT
Aristolochic acid nephropathy (AAN) is a rapidly progressive renal interstitial fibrosis caused by medical or environmental exposure to aristolochic acid (AA). Since the outbreak of AAN in Belgium was reported nearly 30 years ago, the safety of herbal remedies has drawn considerable attention, and AAN has become a global public health problem. Breakthroughs have been made to better understand the disease, including the toxicity of AAs, the possible mechanisms of AAN, the disease patterns, and the pathological features; however, some critical problems remain unresolved. Because of the insidious onset of the disease, the incidence of AAN and the prevalence of exposure to AAs are unknown and might be largely underestimated. During the past decades, AA-containing herbs have been strictly administrated in many regions and the occurrence of AAN has declined sharply, yet cases of AAN are still sporadically reported. Despite the progress in the understanding of the disease’s pathogenesis, there is no effective treatment for delaying or reversing the renal deterioration caused by AAN. Therefore, the risk of exposure to AAs should be taken seriously by public health workers and clinicians. In this review, we updated the latest data on AAN, summarized the advances throughout these years, and put forward some challenges for future research.
ABSTRACT
Non-alcoholic fatty liver disease (NAFLD) is considered to be a manifestation of metabolic syndrome and has become one of the chronic diseases that endanger health around the world. There is still a lack of effective therapeutic drugs in clinical practice. Farnesoid X receptor (FXR) has been a popular target for NAFLD research in recent years. Fexaramine (Fex) is a potent and selective agonist of FXR, and its mechanism of action to improve NAFLD is unclear. Therefore, in this study, a mouse model of NAFLD was constructed using a high-fat, high-cholesterol diet and treated with Fex orally for 6 weeks. We evaluated the ameliorative effect of Fex on disorders of glucolipid metabolism in NAFLD mice, and preliminarily explored its potential mechanism of action. The animal experiments were approved by the Animal Ethics Committee of Shanghai University of Traditional Chinese Medicine (approval number: PZSHUTCM210913011). In this study, it was found that 100 mg·kg-1 Fex significantly inhibited body weight gain, alleviated insulin resistance, improved liver injury and lipid accumulation in NAFLD mice. The effect of Fex on the expression of hepatic intestinal FXR and its target genes in NAFLD mice was further examined. Analysis of serum and hepatic bile acid profiles and expression related to hepatic lipid metabolism. It was found that Fex could stimulate intestinal FXR, promote fibroblast growth factor 15 (FGF15) secretion, inhibit the expression of cytochrome P450 family 7 subfamily A member 1 (CYP7A1), the rate-limiting enzyme of bile acid synthesis in liver, regulate bile acid synthesis by negative feedback, and improve the disorder of bile acid metabolism. At the same time, Fex reduces liver lipid synthesis and absorption, increases fatty acid oxidation, thus improving liver lipid metabolism. This study shows that Fex can improve NAFLD by activating intestinal FXR-FGF15 signal pathway and regulating liver lipid metabolism.
ABSTRACT
The "toxicity" and safety of traditional Chinese medicines have been seriously concerned. Alkaloids are the main pharmacodynamic components of many kinds of traditional Chinese medicines, which show strong biological activity at low concentration. It will also cause toxic side effects but if used improperly. Some alkaloids are both active and toxic, and the safety of related traditional Chinese medicines is particularly noteworthy. The efficacy or toxicity of alkaloids may be the result of the combined action of parent compounds and metabolites, which is not only related to the structural types of compounds, but also has obvious species differences between humans and animals. This review focused on the alkaloids contained in the "toxic" traditional Chinese medicines that are officially recorded in Chinese Pharmacopoeia and the metabolism patterns of alkaloids with different structures as well as the enzymes involved were summarized and discussed by referencing the publications in recent two decades. The present study will be beneficial to the rational use of these traditional Chinese medicines in clinic.
ABSTRACT
Sophorae Flavescentis Radix is the dried root of Sophora flavescens Ait. and Sophorae Tonkinensis Radix et Rhizoma is the dried root and rhizome of Sophora tonkinensis Gagnep. The two drugs are both from the same genus Sophora, having similar and different compositions and efficacies, however, their differences are not fully demonstrated in current standard. In this study, the high-performance thin-layer chromatography with multi-dimensional and multi-level features combined with electric spray mass spectrometry (HPTLC-ESI-MS) was used to discover and identify the characteristic zones in extracts of Sophorae Flavescentis Radix and Sophorae Tonkinensis Radix et Rhizoma, after optimizing the preparation method of the test solution and chromatographic parameters. As a result, 17 main characteristic zones were found on HPTLC chromatograms of Sophorae Flavescentis Radix and Sophorae Tonkinensis Radix et Rhizoma, among them, besides 3 known chemicals, another 12 unknown components were identified by HPTLC-ESI-MS, they are 1 alkaloid and 11 flavonoids. The identification results were verified by the reference standards partially and nuclear magnetic resonance spectra after guided-isolation. Finally, a unified HPTLC specific identification method with different markers was established to identify Sophorae Flavescentis Radix and Sophorae Tonkinensis Radix et Rhizoma simultaneously. Thanks to abundant chemical information provided when using diverse polarity mobile phases and derivatization reagents, the HPTLC technology offers a convenient strategy for discovery, quality evaluation, and identification of target chemicals when connecting with mass spectrometry.
ABSTRACT
OBJECTIVE To explore the risk signal of ixazomib and provide a reference for clinically rational drug use. METHODS The Open Vigil 2.1 online tool was used to extract the data of adverse drug events （ADE） reported by the database of FDA adverse event reporting system （FAERS） from the launch of ixazomib in America （November 20th， 2015） to the latest update of the Open Vigil website （March 31st， 2023）. The data were mined by using the proportional reporting ratio （PRR） and Bayesian confidence propagation neural network （BCPNN） of the proportional imbalance method. The signals were coded by system organ class （SOC） and preferred term （PT） according to MedDRA v25.1. RESULTS A total of 13 841 ADE reports with ixazomib as the “primary subject” were extracted， involving slightly more male patients （49.53%）， and most of them were 65 years old and above （72.48%）； the reports came from 57 countries/regions， mainly America （52.90%）. A total of 186 positive signals were excavated， with 51 high-intensity， 99 medium-intensity， and 36 low-intensity signals， involving 19 SOCs. The top 50 PT in frequency and signal intensity of PRR included neuropathy peripheral （414 cases， high-intensity signal）， platelet count decreased （379 cases， high-intensity signal）， thrombocytopenia （360 cases， high-intensity signal）， cytopenia （75 cases， high-intensity signal） and neurological symptoms （41 cases， high-intensity signal）. SOC involved included nervous system disorders， investigations， and blood and lymphatic system disorders. ADE occurred most frequently in gastrointestinal diseases （2 588 cases）， including diarrhea （1 077 cases， high-intensity signal）， nausea （737 cases， medium-intensity signal）， vomiting （459 cases， medium-intensity signal）， constipation （275 cases， medium-intensity signal）， and so on. The positive signals of infections and infestations contained the largest number of PTs， and most of them were not recorded in the drug instruction， including 12 high-intensity signals （1 030 cases） and 30 medium-intensity signals （627 cases）， which were mainly distributed in lung infection， upper respiratory infection， gastrointestinal infection， sepsis， herpes zoster and so on. The signals of cardiac amyloidosis （7 cases， high-intensity signal） and acute coronary syndrome （14 cases， high-intensity signal） of cardiac disorders and renal dysfunction （91 cases， medium-intensity signal） of renal and urinary disorders were all strong and had not been recorded in the drug instruction. CONCLUSIONS In addition to routine attention to the common ADE of ixazomib in gastrointestinal diseases，nervous system disorders and blood and lymphatic system disorders， clinical attention should also be paid to various infections that may occur during the treatment of patients， and the occurrence of cardiovascular toxicity and renal dysfunction should be monitored.
ABSTRACT
Objective:To observe the clinical efficacy of combining electroacupuncture with long needle sacral nerve acupuncture in the treatment of diabetic overactive bladder.Methods:A total of 90 patients with diabetic overactive bladder were randomly divided into an observation group and a control group, each of 45. In addition to the basic treatment for diabetes, the observation group received electroacupuncture combined with long needle sacral nerve acupuncture 5 times a week for 4 weeks, while the control group was given 5mg of oral solinax succinate once a day as a course of treatment. One week before the beginning of the experiment and one week before its end, urination diary cards were used to record the average number of times of daytime and nighttime urination daily, as well as any urgent urination and urinary incontinence during the week. Bladder overactivity syndrome score (OABSS), the bladder overactivity quality of life questionnaire (OAB-q), maximum urine flow rate (Qmax) and mean urine flow rate (Qave) were employed to quantify urination status, life quality and the urodynamics of the 2 groups before and after the treatment.Results:After the treatment, significant improvement was observed in the average weekly incidence of daytime and nighttime urination, of urgent urination and of urinary incontinence. The average OABSS, OAB-q, Qmax and Qave scores improved in both groups, but the experimental group showed significantly better improvement than the control group.Conclusion:Electroacupuncture combined with sacral nerve needling can significantly reduce the frequency of urination, relieve the symptoms of urgent urination and incontinence, and improve the rate of urine flow, improving the life quality of patients with diabetic overactive bladder.
ABSTRACT
Objective:To investigate the effects of breast milk to total milk intake ratio during hospitalization on the duration of antibiotic therapy in preterm infants less than 34 weeks of gestation.Methods:Clinical data of preterm infants ( n=1 792) less than 34 gestational weeks were retrospectively collected in 16 hospitals of Jiangsu Province Neonatal-Perinatal Cooperation Network from January 1, 2019, to December 31, 2021. The days of therapy (DOT) were used to evaluate the duration of antibiotic administration. The median DOT was 15.0 d (7.0-27.0 d). The patients were divided into four groups based on the quartiles of DOT: Q 1 (DOT≤7.0 d), Q 2 (7.0 d<DOT≤15.0 d), Q 3 (15.0 d<DOT≤27.0 d) and Q 4 (DOT>27.0 d) groups. According to the breast milk intake ratio (breast milk intake to total milk intake during hospitalization×100%), they were also divided into four groups: very-low-ratio breastfeeding group (breast milk intake ratio≤25%), low-ratio breastfeeding group (25%<breast milk intake ratio≤50%), medium-ratio breastfeeding group (50%<breast milk intake ratio≤75%) and high-ratio breastfeeding group (breast milk intake ratio>75%). Univariate analysis ( Chi-square test and Kruskal-Wallis rank-sum test) was used to analyze the factors influencing DOT. Spearman correlation analysis and trend Chi-square test were used to explore the relationship between breast milk intake ratio and DOT. After using multiple imputations to address missing data, two models were constructed after adjusting for different factors, and multinomial logistic regression model was applied to evaluate the effects of the breast milk intake ratio on DOT. Finally, sensitivity analysis was conducted to assess the stability of the models. Results:(1) Of the 1 792 preterm infants, there were 507 (28.3%) in the Q 1 group, 422 (23.5%) in the Q 2 group, 438 (24.4%) in the Q 3 group and 425 (23.7%) in the Q 4 group. (2) The median values of DOT in the very-low-ratio, low-ratio, medium-ratio and high-ratio breastfeeding groups were 20.0 d (11.0-31.0 d), 20.0 d (11.0-32.0 d), 13.0 d (6.0-25.8 d) and 10.0 d (4.0-21.0 d), respectively. Compared with the very-low-ratio and low-ratio breastfeeding groups, the medium-ratio and high-ratio breastfeeding groups had shorter DOT (all P<0.05). (3) After adjusting for factors with P<0.1 (prenatal glucocorticoid exposure, antimicrobial use within 24 h before delivery, gestational age at delivery, birth weight, Apgar score≤7 at 1 min, neonatal respiratory distress syndrome, infectious pneumonia and early-onset neonatal sepsis) between the DOT quartile groups, it showed that medium-ratio and high-ratio breastfeeding were protective factors in contrast to very-low-ratio breastfeeding in the Q 2, Q 3 and Q 4 groups as compared with the Q 1 group [Q 2 group: OR=0.50 (95% CI: 0.30-0.85) and OR=0.36 (95% CI: 0.26-0.51); Q 3 group: OR=0.31 (95% CI: 0.18-0.55) and OR=0.20 (95% CI: 0.14-0.29); Q 4 group: OR=0.22 (95% CI: 0.12-0.42) and OR=0.17 (95% CI: 0.12-0.26)]. Conclusion:Breast milk intake accounting for over 50% of total milk intake has a positive impact on reducing DOT in premature infants requiring antibiotics, which suggests that breastfeeding should be actively encouraged.
ABSTRACT
Objective:To investigate the urinary sediment findings and the clinicopathologic features of IgA nephropathy (IgAN) patients with acute kidney injury (AKI).Methods:It was a retrospective study. The patients with renal biopsy-proven primary IgAN in Peking University First Hospital from January 31, 2013 to July 31, 2015 were selected. According to whether AKI occurred at renal biopsy or not, the patients were divided into AKI group and non-AKI group. Morning urine samples were obtained on the day of renal biopsy. Urine sediments, including various cells and casts, were examined. The clinical data, urinary sediments, and renal pathological changes were compared between the two groups. Logistic regression analysis was performed to identify the association between clinical pathological changes, urinary sediment indicators and AKI, or clinical pathological changes and urinary sediment indicators.Results:There were 502 IgAN patients enrolled in this study, with age of (36.1±12.1) years old and 261 males (52.0%). The incidence of AKI was 11.4% (57/502) among the enrolled patients at the time of renal biopsy. Common causes of AKI included gross hematuria-induced AKI (10 cases), acute tubulointerstitial nephritis (10 cases), crescentic IgAN (9 cases), malignant hypertensive renal damage (6 cases), and multiple etioloqy or unknown etiology (22 cases). Compared with non-AKI group, AKI group had higher proportions of males and malignant hypertension, higher levels of proteinuria and urinary erythrocyte counts, and higher frequencies of gross hematuria, leukocyturia, renal tubular epithelial cells, and granular casts (all P<0.05). AKI group also had higher proportions of severe tubular atrophy/interstitial fibrosis (T2) and cellular/cellular fibrous crescent formation (C2) than non-AKI group (both P<0.05). Logistic regression analysis results showed that, there were statistically significant differences in the correlation between AKI and gender, 24 h urinary protein, urinary erythrocyte counts, granular casts and renal tubular atrophy/interstitial fibrosis (T) scores (all P<0.05). Hematuria, leukocyturia, red blood cell casts, white blood cell casts, granular casts, and fatty casts were correlated with endothelial hypercellularity (E) and cellular/cellular fibrous crescent formation (C) scores, respectively (all P<0.05). Hematuria was correlated with mesangial hypercellularity (M) scores ( OR=2.613, 95% CI 1.520-4.493, P=0.001). Hematuria ( OR=1.723, 95% CI 1.017-2.919, P=0.043) and fatty casts ( OR=2.646, 95% CI 1.122-6.238, P=0.026) were correlated with segmental sclerosis or adhesion (S) scores. Leukocyturia ( OR=1.645, 95% CI 1.154-2.347, P=0.006) and fatty casts ( OR=2.344, 95% CI 1.202-4.572, P=0.012) were correlated with T scores. Epithelial cell cast was correlated with C scores ( OR=1.857, 95% CI 1.174-2.939, P=0.008). Conclusions:AKI is a common complication among IgAN patients with diverse etiology and more severe clinicopathological features. Urinary sediment findings can reflect renal pathological changes to some extent, and therefore assist in the clinical diagnosis and treatment of IgAN patients with AKI.
ABSTRACT
Objective:To summarize the clinical manifestations, gene variations, diagnosis and treatment of 3 cases with SLC35A2 variations characterized by congenital glycosylation disorder Ⅱm (CDG Ⅱm). Methods:A total of 3 patients admitted to the Department of Pediatrics of Xiangya Hospital of Central South University in China from 2018 to 2020 were examined in detail. The studies till January 2022 were searched with key words of "congenital disorders of glycosylation Ⅱm", " SLC35A2" and "CDG Ⅱm" in both English and Chinese in the databases of China National Knowledge Infrast Ructure (CNKI), Wanfang, Online Mendelian Inheritance in Man and PubMed, and the clinical manifestations, genetic variation, treatments and prognosis of patients with SLC35A2 mutation were summarized. Results:The patients all presented with intractable infantile spasm and global developmental delay, onset in infancy. A variety of antiepileptic treatments had temporary and partial efficacy. Otherwise, proband 2 and 3 presented with abnormal glutamic-pyruvic transaminase and increased platelets. Funduscopy showed dysplasia of the retinal pigment epithelium in both eyes, and they both received D-galactose treatment. A total of 22 relevant case reports, including 99 patients, were collected. The 99 patients all were heterozygous mutations, and a total of 75 different variation sites were reported. The clinical manifestations were characterized by global developmental delay or mental retardation ( n=89), epileptic seizure ( n=75), hypotonia ( n=57), facial deformity ( n=57), skeletal abnormality ( n=50), visual impairment ( n=42), elevated glutamic-pyruvic transaminase ( n=31), gastrointestinal symptoms ( n=28), skin deformity ( n=26), microcephaly ( n=23) and congenital heart disease ( n=12). Craniocerebral magnetic resonance imaging may be normal in the early stage. With age, magnetic resonance imaging may show abnormal white matter signals, brain atrophy, dysplasia of corpus callosum, delayed myelination, enlargement of lateral ventricle, brain stem atrophy and so on. Studies have shown that galactose treatment may be effective. Conclusions:SLC35A2 variants lead to CDG Ⅱm, whose clinical manifestations mainly include epileptic encephalopathy and global developmental delay. Multiple antiepileptic therapies can temporarily or partially control seizures, while oral galactose may improve the clinical symptoms, showing its prospect as a dietary therapy.
ABSTRACT
Objective:To analyze the clinical characteristics of a child with developmental epileptic encephalopathy caused by NR4A2 gene mutation, and to summarize the clinical phenotypes and genotypes to improve the clinician′s understanding of this disease. Methods:The clinical data of a child with developmental epileptic encephalopathy admitted to Linyi People′s Hospital in August 2022 were collected, video electroencephalogram, craniocerebral magnetic resonance imaging and family whole exon sequencing were improved, and the suspected mutation sites were verified by Sanger sequencing. Relevant literature was consulted to summarize the clinical phenotypes and genetic characteristics of nervous system diseases caused by NR4A2 gene. Results:It was found that there was a heterozygous missense mutation at the locus c.866G>A (p.A289H) of NR4A2 gene in the child, which was a de novo mutation, and both parents were wild type. According to the American Society of Medical Genetics and Genomics variation classification, it was assessed as a suspected pathogenic variation. Through literature review, there were 16 related cases reported internationally, with clinical phenotypes including mental retardation/mental retardation, language disorders, seizures, muscle tone changes and different psychological and behavioral problems. Conclusions:The NR4A2 gene is not only associated with dopa responsive disorders, but also with neurological development, intellectual impairment, language development delay, and epilepsy. The mutation of NR42A gene c.866G>A (p.A289H) is the genetic cause of the patient, and the detection of this locus expands the NR4A2 gene spectrum. NR4A2 gene is one of the pathogenic genes of developmental epileptic encephalopathy.
ABSTRACT
Objective:To analyze the clinical phenotype and gene sequencing results of a child with hyperekplexia, and to clarify her genetic etiology.Methods:The clinical information of the child was collected, and the whole exome sequencing of the child and her parents was performed. The suspected pathogenic variants were verified by Sanger sequencing and bioinformatics analysis.Results:There was a 12 years old girl, who was hospitalized in the Department of Pediatric Neurology of Linyi People′s Hospital because of "paroxysmal limb stiffness for more than 11 years and aggravated for half a month" on July 4, 2022. The girl showed exaggerated startle reflexes and generalized siffness in response to external sudden, unexpected stimuli, occasionally accompanied by apnea and cyanosis, frequent attacks occurred several times a day, lasting for 1-30 minutes, and early head and abdomen flexion can be relieved. She showed normal growth and development, no abnormality in brain magnetic resonance imaging and video electroencephalogram during seizure. The whole exome sequencing showed that there was a missense heterozygous mutation c.643T>C(p.W215R) in the SLC6A5 gene of the child. Neither of the parents carried this mutation, which was a novel and de novo variant. According to the guidelines of American College of Medical Genetics and Genomics, this variant was a likely pathogenic variant [PS2: de novo (both maternity and paternity confirmed) in the patient with the disease and no family history; PM2: undetected variants in the normal population; PP3: multiple softwares predicted that this mutation would have harmful effects on genes or gene products], and highly conserved. Swiss modeling found that the hydrogen bond of the modified amino acid also changed. Conclusions:Hyperekplexia is relatively rare and prone to misdiagnosis. The main clinical features are excessive startle reflexes (limb shaking, or jumping) to unexpected external stimuli, resulting in overall stiffness, normal growth and development, and normal video electroencephalogram during the seizure. The likely pathogenic heterozygous missense variant c.643T>C (p.W215R) of SLC6A5 gene is the genetic cause of this case.
