2.Application of intestinal microbiota detection technology in the prevention and treatment of children′s intestinal infections
Chinese Journal of Laboratory Medicine 2021;44(4):280-284
The low diversity and large inter-individual differences of children′s intestinal microbiota are associated with antibiotic-resistant bacteria colonization and infection. Therefore, rapid and accurate detection of intestinal microbiota dysbiosisis of great significance for the prevention and treatment of intestinal infection and the rational use of antibiotics. The current intestinal pathogens detection methods have either poor accuracy or low throughput. The developing multi-omics technology can accurately detect known and unknown pathogens and can also be used to evaluate the intestinal microbiota state comprehensively. This technology will be widely applied in the detection of intestinal infections in children.

Objective: To investigate the relationship between 24-hour ambulatory pulse pressure (24hPP), 24-hour ambulatory pulse pressure index (24hPPI), night-time ambulatory pulse pressure index (NPPI) and coronary artery disease (CAD) occurrence in hypertension patients. Methods: A total of 305 subjects received ambulatory blood pressure monitoring (ABPM) in our hospital from 2016-05 to 2016-07 were enrolled. Base on ABPM information, 24hPP, 24hPPI and NPPI were calculated to analyze their relationship to CAD occurrence. 24hPP was defined by 24-hour mean systolic blood pressure (24hSBP) minus 24hDBP, 24hPPI by the ratio of 24hPP/24hSBP and NPPI by the ratio of night (22:00-6:00) PP/SBP. Results: There were 222/305 (72.8%) subjects with hypertension. Compared with normotension subjects, hypertension patients had increased 24hPP: (49.0±11.6) mmHg vs (42.2±7.4) mmHg, P<0.001, 24hPPI: (0.39±0.06) vs (0.37±0.05), P=0.004 and NPPI: (0.40±0.07) vs. (0.38±0.06), P=0.009 respectively. 116/222 (52.3%) hypertension patients suffered from CAD. Compared with non-CAD patients, CAD patients presented elevated 24hPP: (50.9±12.2) mmHg vs (47.0±10.6) mmHg, P=0.013, 24hPPI: (0.41±0.07) vs. (0.38±0.06), P<0.001 and NPPI: (0.42±0.07) vs. (0.38±0.06), P<0.001 respectively. Among 83/305 (27.2%) normotension subjects, the above indexes were similar between CAD patients and non-CAD subjects. Logistic regression analysis demonstrated that with adjusted age, gender, body mass index (BMI) and antihypertensive medication, 24hPPI [OR=1.95, 95% CI 1.11-3.44, P=0.020] and NPPI [OR=2.21, 95% CI 1.28-3.82, P<0.01] were related to CAD occurrence. ROC curve analysis showed that 24hPPI and NPPI were superior to 24hPP for CAD screening and prediction in hypertension patients. Conclusion: 24hPPI and NPPI were closely related to CAD occurrence in hypertension patients, they were both helpful for CAD screening and prediction in hypertension patients.

Objective: To investigate the relationship between blood pressure variability and ambulatory arterial stiffness index (AASI) in both normal subjects and hypertensive patients.
Methods: A total of 280 consecutive subjects without antihypertensive medication were studied. All subjects received ambulatory blood pressure monitoring (ABPM) and AASI was calculated as 1 minus the regression slope of diastolic blood pressure value vs systolic blood pressure value according to ABPM recording.
Results: ① There were 161 subjects with male gender, 138 patients with hypertension, and the average age was (50.4 ± 13.3) years.②Pearson analysis indicated that AASI was related to age (r=0.272, P<0.001), 24-hour mean pulse pressure (r=0.504, P<0.001) , nocturnal diastolic blood pressure dipping (r=-0.334, P<0.001) and standard deviation of 24-hour diastolic blood pressure (r=-0.520, P<0.001).③AASI in anti-dipper hypertensive patients was higher than that in dipper patients, P<0.05;while AASI between dipper and non-dipper patients, dipper and extreme-dipper patients were similar, P>0.05 respectively.④Multiple linear regression analysis demonstrated that with adjusted age, gender, BMI and blood pressure, AASI was independently related to 24-hour mean pulse pressure (β=0.003, P<0.001), nocturnal diastolic blood pressure dipping (β=-0.001, P<0.05), standard deviations of 24-hour systolic blood pressure (β=0.032, P<0.001) and 24-hour diastolic blood pressure (β=-0.064, P<0.001), standard deviation of 24-hour heart rate (β=0.006, P<0.001).
Conclusion:AASI is closely related to blood pressure variability, it’s a comprehensive index for arterial stiffness and blood pressure variability.

7.Advance in molecular genetic research on X-linked syndromic hearing impairment.
Chinese Journal of Medical Genetics 2017;34(6):928-933
In addition to hearing impairment, syndromic hearing impairment is often accompanied by disorders of urinary, skeletal, muscular, nervous, and ocular systems. Genetic factors have shown to play an important role in the pathogenesis of deafness. Mutations of X-linked genes may cause syndromic hearing impairment. Gene mapping, linkage analysis and next-generation sequencing may facilitate delineation of the pathogenesis of X-linked syndromic hearing impairment. This article reviews recent progress in molecular genetic research on X-linked syndromic hearing impairment, which may shed light for the diagnosis and treatment of these diseases.

Chinese Journal of Cerebrovascular Diseases 2019;16(3):129-132
Objective To investigate the expression differences of poly adenosine diphosphate ribose polymerase 1 (PARP-1) in the human intracranial ruptured and unruptured aneurysm walls. Methods Consecutive patients with intracranial aneurysm treated with craniotomy clipping surgery in Drum Tower Hospital, Nanjing University School of Medicine (n = 1) and General Hospital of Eastern War Zone (n = 12) from January 2014 to September 2018 were enrolled retrospectively. Seven of them were ruptured aneurysms and 6 were unruptured aneurysms. The expression of PARP-1 in aneurysm walls was detected by immunohistochemistry. Results Immunohistochemistry staining showed that the positive expression of PARP-1 was brown-yellow and mainly located in nuclei; in the unruptured aneurysm walls,the number of PARP-1 positive cells was small, the distribution was sparse,and it expressed in the whole layer of the aneurysm wall;in the ruptured aneurysm walls,PARP-1 positive cells were densely distributed in the outer membrane of the vessel walls. Statistical analysis showed that the positive expression of PARP-1 in the ruptured aneurysm walls was higher than that in the unruptured aneurysm walls. The difference was statistically significant(160 ± 19 vs. 56 ± 14,1 = 4. 291, P < 0. 01) . Conclusion The expression of PARP-1 in the ruptured aneurysm walls is significantly higher than that in the unruptured aneurysms,which may play a role in the rupture of intracranial aneurysms.

DNA hydroxymethylation modification is an important part of genome epigenetic regulation.The demethylation process from 5-methylcytosine (5-mC) to 5-hydroxymethylcytosine (5-hmC) is catalyzed by Tet protein.Abnormal genomic methylation leads to the occurrence of a variety of tumors.Hydroxymethylation is modified as a kind of demethylation and is inseparable from tumorigenesis.The expression of 5-hmC changes accompanied with the development and progression of digestive system tumors,which may be associated with the TET protein family and IDH mutation.It suggested that DNA hydroxymethylation is involved in the development and progression of digestive system tumors.This paper reviews the relationship between DNA hydroxymethylation and digestive system tumors,and aims to provide a new direction for the study of Hydroxymethylation modification in digestive system tumors.
