Objective To explore the effects of PDCA-based self-management intervention model on health behavior and medication adherence in aged patients with percutaneous coronary intervention (PCI). Methods Totally 130 aged patients treated by PCI were randomly divided into the intervention group and the control group with 65 patients. The patients in the control group received routine health education, and the patients in the intervention group received PDCA-based self-management intervention model. All patients were investigated with Coronary Heart Disease Self-Management Behavior Scale (CSMS) and Health Promoting Lifestyle Profile (HPLP) and Medication Compliance Scale (MMAS-8) 3 months and 6 months after discharge. Results Six months after discharge, the score of self-management and healthy behavior and medication adherence were 96.98 ± 14.12, 131.86 ± 16.53, 7.18 ± 0.69 respectively in the intervention group, and the score of them were 86.04 ± 11.78, 105.33 ± 10.97, 5.69 ± 1.29 respectively in the control group, and the difference was statistically significant (t=10.981, 10.793, 7.438, P<0.05 or 0.01). Conclusions PDCA-based self-management intervention model is a patient-centered, problem-oriented, dynamic and interactive health education intervention. It may be helpful in improving PCI patients′ health behavior and medication adherence after discharge. And it may establish lasting self-management skills, and is worthy of application and promotion.

Objective To investigate the pathogenic mechanism of Campylobacter jejuni(C.jejuni) associated with Guillain-Barré syndrome(GBS) and provide strategy for gene modification, the cstⅡ gene from 8 GBS-associated C.jejuni strains were compared with that from 3 GBS-unrelated C.jejuni strains, getting the base and amino acid mutations, the changes of secondary structures and finding the region which may be responsible for the pathogenicity of C.jejuni inducing GBS. Methods Three GBS-associated C.jejuni strains isolated from stools of GBS patients in north China were selected and cultured, which has been confirmed as GBS-associated by animal model. After sequencing the genome of them, the nucleotide sequences of cstⅡ gene were got through sequence alignment. The nucleotide sequences and deduced amini acid sequences of 3 GBS-associated cstⅡ genes were compared with that from 3 GBS-unrelated C.jejuni strains through bioinformatics software, getting the base and amino acid mutations, the changes of secondary structures. Other 5 GBS-associated cstⅡ genes were also aligned to know whether the differences we got above makes sense. In this way the genetic differences between two kinds of C.jejuni strains may be found and speculating the gene region related to the pathogenicity of GBS became possible. Results The cstⅡgene of 3 GBS-associated C.jejuni strains were all composed of 876 base pairs. Compared with GBS-unrelated C.jejuni strains, there were 9 consistent mutation sites in cstⅡ gene of LL and QYT stains, leading to 3 consistent amino acid mutation. The amino acid mutation of 114 and 182 sites in LL and QYT stains existed in other 5 GBS-associated C.jejuni strains. The sole amino acid mutation of ZHX strain -169 site, located near the 182 site. The seventh α-helix(165-180 region)of the secondary structure of the amino acid sequence from GBS-associated strains were shorter than that from GBS-unrelated strains, and the shorter regions were opened to form β-sheet or coli, which also existed in other GBS-related strains in this study.75% of the GBS-associated cstⅡ genes were Asn-51, while 25% of the GBS-associated and all of the GBS-unrelated cstⅡ genes were Thr-51.LL strain showed highly identity to other GBS-unrelated strains in this study. Conclusion The 165-180 segment of secondary structures in cstⅡ gene from local 3 GBS-associated C.jejuni strains are probably the responsible region involved in inducing GBS. The senior structure changes in this region may affect the activity of sialyltransferase and the structures of ganglioside epitope, so that the C.jejuni can acquire the pathogenicity of GBS. This finding may give a clue to genetic modified site. The bi-functional cstⅡ of C.jejuni may be related to the pathogenicity of GBS. The cstⅡ of LL strain to some extent represents the characteristics of Asian strains, which may directs strains monitoring.

Objective:A retrospective analysis was performed on clinical characteristics and deoxyguanosine kinase DGUOK gene mutations in a family with hepatocerebral mitochondrial DNA depletion syndrome (MTDPS). Methods:The clinical data, treatment process and gene detection results of a child with MTDPS in the second hospital of Hebei Medical University in April 2019 were analyzed and summarized.Results:Proband was a girl.From the first week of infantile, she suffered from recurrent hypoglycemia, hyperlactic acid, progressive cholestatic liver dysfunction, coagulopathy, difficult feeding, slow growth of body mass, microcephaly, hypotonia, and gradul intermittent binocular tremors, and eventually failed to thrive.Gene testing identified two compound heterozygous mutations c. 42-c.43insTTCA(p.F15fs129X)/c.808-1(IVS6)G>A in DGUOK gene.The former was a frame-shift mutation resulted in truncated protein and the later was a splicing mutation resulted in abnormal splicing.Each parent was a heterozygous carrier, and there were no mutations in the two sites with her elder sister. Conclusions:Both mutations were first reported worldwide. DGUOK gene mutations with MTDPS are important causes of infant liver failure.When hypoglycemia, hyperlactic acidemia and liver dysfunction occur in newborn and infant, MTDPS related gene DGUOK gene sequencing screening should be considered for early definitive diagnosis, or, when acute liver failure happen in infant and childhood, neuromuscular involvement is insufficient.

Objective To investigate the Camtrylobacterjejuni's risk factors which were associated with the development of Guillain-Barre syndrome( GBS), the galE gene of C. jejuni strains were sequenced and the sequencing results were compared with other C. jejuni strains. Methods Selecting three GBS-asso-ciated C.jejuni strains isolated from stools of GBS patients who had been diagnosed as AMAN pattern by clin-ical and electrophysiological test from Hebei province, China. After sequencing galE gene, the results were spliced and assembled into a complete sequence by the terminals overlapped each other. The sequences of galE gene were compared with the corresponding sequences in GenBank to find the mutation and constructed the phylogenetic tree. Results The variation frequency of galE sequences of GBS-associated C. jejuni were higher than that of non-GBS-associated C. jejuni. The phylogenetic analysis demonstrated that each of the three C. jejuni strains was separately genetically closed to three strains which sequences have published in GenBank. The alignment with the related sequence of NCTC11168 shows that there are 4 same mutations in the galE gene of the three C. jejuni strains. The phylogenic tree reflected the regional feature of C. jejuni. Conclusion The probability of sequence variation of galE of GBS-associated C.jejuni is significantly higher than non-GBS-associated C. jejuni strains, the relation between the variation and GBS-pathogenesis remains to be further confirmed. The mutations found in the three C. jejuni strains established the foundation for ex-ploring the biologically characteristic of GBS-associated C. jejuni strains.

BACKGROUND: Recombinant human bone morphogenetic protein-2 (rhBMP-2) has been widely used on clinic; however, there are still few reports addressing rhBMP-2-induced osteogenesis in intervertebral disc.OBJECTIVE: To verify the effect of rhBMP-2 to induce interbody fusion in rabbits.DESIGN, TIME AND SETTING: Randomized controlled animal study and multi-level evaluation, which was performed in Affiliated Hospital of Medical College of Qingdao University from February to July 2007.MATERIALS: 24 adult New-Zealand rabbits weighing 3.5-4.5 kg were used to expose L4-5 and L5-6 intervertebral disc; rhBMP-2 (1 mg/ampoule, purity≥95%) was provided by Beijing Bailingke Biological Products Co., Ltd.METHODS: 24 rabbits were randomly divided into experimental group and control group with 12 rabbits for each. In the experimental group, saline (20 μL, containing 200 μg rhBMP-2) was injected into nucleus pulposus of L4-5 intervertebral disc; equivalent saline was inserted into nucleus pulposus of L5-6 intervertebral disc as controls. Rabbits in the control group were injected with saline (20 μL) into nucleus pulposus of L4-5 intervertebral disc.MAIN OUTCOME MEASURES: Morphological changes of injected segments were observed by hand-feeling check together with histological and imaging tests at 10, 30, 60, and 90 days postoperatively.RESULTS: 24 rabbits were included in the final analysis. ①In the experimental group, the motion range of L4-5 segment was not limited at 10 days postoperatively, and lightly limited at 30 days, but severely limited at 60 days postoperatively; L4-5 segment was fixed tightly at 90 days postoperatively. Moreover, motion range of L5-6,segment and articular motion range in the control group were not changed remarkably. ② L4-5 interbedy space was narrowed at 10 days or even disappeared at 90 days postoperatively, and then osteogenesis fusion was formed. Transmittance of intervertebral space in the L5-6 segment and in the control group was not changed obviously. ③ Nucleus pulposus was gradually shrunk at 10 days postoperatively; partial cartilage endplate transformed into mature woven bone, and collagen fiber structure of annulus fibrosus gradually disappeared at 90 days postoperatively. A lot of mesenchymal cells were aggregated surrounding annulus fibrosus at 10 and 30 days postoperatively. Moreover, mature woven bone was formed in annulus fibrosus near to cartilage endplate at 90 days postoperatively. However, histological and morphological changes were not found in the control group at those four time points.CONCLUSION: rhBMP-2 can induce intervertebral disc osteogenesis so as to achieve interbody fusion.

Objective:To investigate clinical characteristics and ABCB11 gene mutations in probands suffering from progressive familial intrahepatic cholestasis type 2(PFIC2). Methods:The clinical data involving manifestations and laboratory examinations of 2 probands with PFIC2 admitted to Pediatric Digestive and liver Clinic in Second Hospital of Hebei Medical University during January 2017 to December 2018 were retrospectively analyzed.Target capture high-throughput sequencing, genome-wide gene copy number variation(CNV) detection and validation were performed on probands and their parental DNA.Results:The age of onset for the 2 probands ranged from 2 to 5 months, and they had hepatosplenomegaly, severe cholestasis, pruritus, and binding bilirubin/ total bilirubin (proband 1: 51.8%-77.5%, proband 2: 47.1%-66.5%). Bile acid and aminotransferase[mainly aspartate transaminase (AST)] increased, but γ-glutamyltransferase(GGT) remained normal.Compound heterozygous mutations of ABCBll gene were discovered in proband 1: single strand deletion/c.3213+ 5G>A splicing mutation, and deletion mutation were spontaneous mutation.A total of 2.256 Mb(chr2 2q24.3q31.1)was missing, whereas splicing mutation was originated from her father.Polymorphisms with Val444Ala(T1331C)and Ala1028Ala(A3084G)were proved in proband 1.Compound heterozygous mutations of ABCB11 gene were revealed in proband 2: c.1483A>G(p.R495G)/c.2594C>T(p.A865V), and both parents were heterozygous carriers.Single-strand 2.256 Mb deletion in proband 1 and 2 mutations in proband 2 were unreported new mutations worldwide. Conclusions:In clinical work, children with cholestasis, elevated bile acid and transaminase(mainly AST), but normal GGT, should be detected for PFIC genes as soon as possible.

OBJECTIVETo assess the association of vitamin D receptor (VDR) gene Fok I and Bsm I polymorphisms with dyslipidemia in elderly male patients with type 2 diabetes of Han nationality.

METHODSA total of 328 elderly male residents of Han nationality in Beijing, including 237 type 2 diabetic patients and 91 healthy control subjects, were enrolled in this study. The diabetic patients were divided into non-dyslipidemia group (DO group, n=134) and dyslipidemia group (DH group, n=103). All the participants were genotyped for Fok I and Bsm I polymorphisms in VDR gene using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing technology, and the results were compared with their clinical characteristics.

RESULTSFor Fok I, the frequency of F allele was significantly higher in the diabetic patients than in the control group (Χ(2)=3.873, P=0.049, OR=1.439, 95% CI: 1.001-2.071). In the dominant model, the frequency of FF genotype was significantly higher in the diabetic group (Χ(2)=5.057, P=0.025, OR=1.756, 95% CI: 1.072-2.875) as well as in DH group (Χ(2)=6.168, P=0.013, OR=2.06, 95% CI: 1.161-3.663) than in the control group. There was no significant differences in the genotype frequency or allele distribution in other paired groups (P>0.05). Compared with Ff + ff genotype, FF genotype was associated with a significantly decreased average diastolic blood pressure (P=0.039) but significantly increased postprandial blood glucose (P=0.035), triglycerides (P=0.049) and uric acid (P=0.031). No significant difference was detected in genotype frequency or allele distribution of Bsm I polymorphisms between the groups (P>0.05); serum creatinine levels were significantly higher in bb genotype than in BB + Bb genotype group (P=0.011).

CONCLUSIONVDR gene Fok I polymorphisms may be a risk factor for dyslipidemia in elderly male patients with type 2 diabetes among Chinese Han population, where Bsm I polymorphisms are not associated with diabetic dyslipdiemia.
