Objective:To explore the clinical effect of "information knowledge belief practice" model, namely "IKAP theory" nursing intervention model on patients with peritoneal dialysis(PD).Methods:The clinical data of 120 patients with PD treated in The Second Hospital of Tianjin Medical University from January 2020 to December 2020 were analyzed retrospectively. The patients were randomly divided into control group and observation group, with 60 cases in each group. In the observation group, there were 32 males and 28 females with an age range of (56.16±10.25) years, including 18 cases of diabetic nephropathy, 22 cases of chronic glomerulonephritis and 20 cases of hypertensive nephropathy. In the control group, there were 34 males and 26 females, with an age range of (56.27±10.34) years, including 14 cases of diabetic nephropathy, 18 cases of chronic glomerulonephritis and 28 cases of hypertensive nephropathy. The patients in the control group were given routine nursing. In addition to the routine nursing, the patients in the observation group also adopted IKAP mode for nursing intervention. The levels of hemoglobin (HB), serum albumin (ALB), comprehensive nutrition assessment score (SGA) and nursing satisfaction of the two groups were compared before and 6 months after the intervention. The comparison of measurement data before and after intervention in the intervention group was analyzed by paired sample t-test. Frequency data were compared and analyzed by Chi-square ( χ2) test. Results:Before the intervention, there was no significant difference in ALB, Hb levels and SGA between the observation group and the control group( t=1.001~1.743, all P>0.05). After the intervention, the SGA score of the observation group was lower than that of the control group, while the levels of ALB and Hb were higher than those of the control group, and the differences between the two groups were statistically significant ( t=3.411~5.050, all P<0.05). The satisfaction of patients in the observation group was 95%, while that in the control group was 78.33%, and the difference between the two groups was statistically significant ( χ2=7.212, P<0.05). Conclusions:For peritoneal dialysis patients, IKAP nursing intervention can not only effectively improve their nutritional status, but also increase their satisfaction with nursing. IKAP nursing intervention model is worthy of clinical promotion.

OBJECTIVETo achieve early diagnosis for inheritable hearing loss and determine carrier rate of deafness causing gene mutations in order to provide information for premarital, prenatal and postnatal genetic counseling.
METHODSA total of 17 000 dried heel blood spots of normal newborns in Chengdu were collected with informed consent obtained from their parents. Genomic DNA was extracted from dried blood spots using Qiagen DNA extraction kits. Microarrays with 9 common mutation loci of 4 deafness-associated genes in Chinese population were used. Nine hot mutations including GJB2 (35delG, 176del16, 235delC and 299delAT), GJB3 (538C> T), SLC26A4 (IVS 7-2A> G, 2168A> G), and mitochondrial DNA 12S rRNA (1555A> G, 1494C> T) were detected by PCR amplification and microarray hybridization. Mutations detected by microarray were verified by Sanger DNA sequencing.
RESULTSOf the 17 000 new-borns, 542 neonates had mutations of the 4 genes. Heterozygous mutations of GJB2, at 235delC, 299delAT, and 176del16 were identified in 254, 55, and 15 newborns, respectively. Two newborns had homozygous mutation of GJB2, 235delC. Heterozygous mutations at 538C> T of GJB3, 2168A> G and IVS 7-2A> G of SLC26A4 were found in 23, 17 and 128 newborns, respectively. For mutation analysis of mitochondrial DNA 12S rRNA, 1494C> T and 1555A> G were homogeneous mutations in 4 and 42 neonates, respectively. In addition, 6 complexity mutations were detected, which demonstrated that one newborn had heterozygous mutations at GJB2 235delC and SLC26A4, IVS7-2A> G, one had heterozygous mutation GJB2 235delC and 12S rRNA homogeneous mutation, 1555 A> G, one heterozygous mutations at GJB2, 299delAT, and GJB3, 538C> T, one at GJB2, 299delAT and 12S rRNA, 1555 A> G, two at GJB2, 299delAT, and SLC26A4, IVS7-2A> G. All mutations as above were confirmed by DNA sequencing.
CONCLUSIONThe total mutation carrier rate of the 4 deafness genes is 3.19% in healthy newborns at Chengdu. Mutations of GJB2 and SLAC26A4 are major ones (86.5% of total). The mutation rate of mitochondrial DNA 12S rRNA is 2.71‰, which may have deafness induced by aminoglycoside antibiotics. Newborn screening for mutation of genes related to hereditary deafness plays an important role in the early detection and proper management for neonatal deafness as well as genetic counseling for premarital, prenatal and postnatal diagnosis.

Objective:To study the expression and significance of microparticles (MPs), platelets microparticles (PMPs), CD41a +CD62P +PMPs from peripheral blood of patients with ankylosing spondylitis. Methods:Plasma were collected from 47 ankylosing spondylitis (AS) patients and 15 healthy volunteers. The levels of MPs, PMPs, and CD41a +CD62P +PMPs in plasma of AS patients and healthy controls (HC) were detected by flow cytometry. The clinical parameters including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), Bath ankylosing spondylitis disease activity index (BASDAI) were obtained. T test and Spearman linear correlation analysis were used for statistical analysis. Results:The levels of MPs, PMPs, CD41a + CD62P + PMPs in plasma from AS patients were higher than those in plasma from HC [(3 466±641)/μl vs (619±152)/μl, t=2.342, P=0.022; (3 059±628)/μl vs (320±143)/μl, t=2.298, P=0.025; (566±121)/μl vs (47±22)个/μl, t=2.295, P=0.025]. The levels of MPs in plasma of AS patients were positively correlated with BASDAI ( r=0.555, P=0.000 4); and the levels of PMPs in AS patients were positively correlated with BASDAI ( r=0.542, P=0.000 6) but the CD41a +CD62P +PMPs in AS patients were not correlated with BASDAI ( r=0.298, P=0.073 2). The levels of MPs in plasma from AS patients were not correlated with ESR, CRP ( r=-0.016, P=0.917; r=0.035, P=0.817); PMPs in plasma from AS patients were not correlated with ESR, CRP ( r=-0.001, P=0.996; r=0.065, P=0.671). CD41a +CD62P +PMPs in plasma of AS patients were not correlated with ESR, CRP ( r=-0.129, P=0.400; r=-0.410, P=0.789). Conclusion:There is increased expression of MPs, PMPs and CD41a +CD62P +PMPs in AS patients, which is related with disease activity. MPs, PMPs may be involved in the inflammatory response of AS.

OBJECTIVE:
To explore the genetic etiology of a child with D bifunctional protein deficiency (DBPD) born to a consanguineous pedigree.
METHODS:
A child with DBPD who was admitted to the First Affiliated Hospital of Hainan Medical College on January 6, 2022 due to hypotonia and global developmental delay was selected as the study subject. Clinical data of her pedigree members were collected. Peripheral blood samples of the child, her parents and elder sisters were collected and subjected to whole exome sequencing. Candidate variant was validated by Sanger sequencing and bioinformatic analysis.
RESULTS:
The child, a 2-year-and-9-month-old female, had featured hypotonia, growth retardation, unstable head lift, and sensorineural deafness. Serum long-chain fatty acids were elevated, and auditory brainstem evoked potentials had failed to elicit V waves in both ears with 90 dBnHL stimulation. Brain MRI revealed thinning of corpus callosum and white matter hypoplasia. The child's parents were secondary cousins. Their elder daughter had a normal phenotype and no clinical symptoms related to DBPD. Elder son had frequent convulsions, hypotonia and feeding difficulties after birth, and had died one and a half month later. Genetic testing revealed that the child had harbored homozygous c.483G>T (p.Gln161His) variants of the HSD17B4 gene, for which both of her parents and elder sisters were carriers. Based on the guidelines from the American College of Medical Genetics and Genomics, the c.483G>T (p.Gln161His) was rated as a pathogenic variant (PM1+PM2_Supporting+PP1+PP3+PP4).
CONCLUSION
The homozygous c.483G>T (p.Gln161His) variants of the HSD17B4 gene caused by the consanguineous marriage probably underlay the DBPD in this child.
