Objective To discuss the influence of grading nursing care by physician-nurse cooperation decision-making on the quality of patient care and disease outcomes,and evaluate the application feasibility of nursing core system in this nursing mode.Methods 379 patients were admitted to departments of orthopedics and endocrinology from two hospital areas of our hospital from January 2011 to January 2012.Patients were divided into two groups according to nursing process.Patients who were given conventional grading nursing were set as the routine group,and patients receiving physician-nurse collaboration grading nursing were set as the collaboration group.The nursing quality and nursing efficiency,and the disease outcome of patients were compared between the two groups.Results The quality of care,the qualified rate of care plan implementation,the coverage rate of health education of patients and the patient satisfaction rate were higher in the collaboration group than those in the routine group.The performing rate of doctor's orders,the awareness rate of patient disease,the average length of hospital stay,compliance of medical orders and re-admission rate of patients with the same or a related disease within three months were significantly different between two groups.The collaboration group improved the matching degree of nursing grade with disease condition,understanding of professional knowledge,recording of nursing records,deficient nursing process,and communication ability of life knowledge,compared with those of the routine group.Conchusions Nursing grading mode by physician-nurse collaboration decision-making can obviously improve the defmition of grading nursing and the general treatment effect of patients,it significantly improved the quality of grading nursing.

Objective To compare the consistency between interstitial fluid glucose and arterial blood glucose in septic shock patients with different tissue perfusion levels.Methods A prospective investigative study was conducted. Sixty-one septic shock patients with ages above 18 years old admitted to the Department of Critical Care Medicine of Peking Union Medical College Hospital, Chinese Academy of Medical Sciences from April 2013 to December 2013 were enrolled. The real-time continuous glucose monitoring system (RTCGMS) and arterial blood gas analyzer were used to measure the patients' interstitial fluid glucose and arterial blood glucose, and according to the criteria of International Organization for Standardization (ISO) and the median of relative absolute difference (Median RAD), the consistency between interstitial fluid glucose and arterial blood glucose was calculated. Based on the lactate (Lac) level and pulse oxygen perfusion index (PI), the septic shock patients were divided into groups with different degrees of tissue perfusion, the consistency between the interstitial fluid glucose and arterial blood glucose among septic shock patients with different degrees of tissue perfusion was compared by using Bootstrap re-sampling technique.Results Negative correlation existed between PI and Lac (r= -0.272,P < 0.001), which showed the opposite change tendency of organism tissue perfusion. In patients with Lac > 8 mmol/L, their consistency between interstitial fluid glucose and arterial blood glucose was better than that in those with Lac > 2-4 mmol/L, and the 95% credibility intervals (CI) of ISO standardized deviation value was 0.026-38.710 (P < 0.05). In patients with PI ≤ 0.7%, their consistency between interstitial fluid glucose and arterial blood glucose was better than that in those with PI > 0.7%-1.4%, the 95%CI of median RAD difference value was 0.002-0.076, and the 95%CI of ISO standardized deviation value was -27.000 to -0.583 (allP < 0.05); in patients with PI > 3.0%, their consistency between interstitial fluid glucose and arterial glucose was better than that in those with PI ≤ 0.7%, PI > 0.7%-1.4% and PI > 1.4%-3.0%, and the 95%CI of ISO standardized deviation values were 3.322-28.302, 11.988-40.265 and 5.170-33.333 respectively (allP < 0.05).Conclusions When septic shock patients were under low tissue perfusion (Lac > 8 mmol/L or PI ≤ 0.7%), the worse the tissue perfusion, the better the consistency between interstitial fluid glucose and arterial blood glucose; when septic shock patients were under normal local tissue perfusion (PI > 3.0%), the better the local tissue perfusion, the better the consistency between interstitial fluid glucose and arterial blood glucose.

OBJECTIVE To investigate the incidence of the mitochondrial DNA 12SrRNA A1555G and connexin 26 gene (GJB2) in Chinese northwest population with nonsyndromic sensorineural hearing loss,and to explore the relationship between mitochondrial DNA A1555G and mutation of GJB2 gene. METHODS Blood samples were obtained from 221 patients with nonsyndromic sensorineural hearing loss in Northwest of China; Genomic DNA was extracted from the isolated leukocytes ; Screening the mitochondrial A1555G mutation by PCR-Alw26l digestion and sequence analysis, PCR and direct sequencing were used to analyze the coding region of GJB2 gene. RESULTS The homoplasmic A1555G mutation was found in 21 individuals of 221 patients,17 of these 21 patients had been treated with aminoglycosides. Eleven different variants of GJB2 were found in all patients ,the disease-causing mutations of GJB2 were 44 individuals in these patients(44/221), The mutation 235delC is found in 54.54 % of all disease-causing mutations ; Among 21 patients with the A1555G mutation, 11 cases were found polymorphic change in GJB2 gene ,only 1 case had V37I heterozygous mutations ,other 9 cases were not found any nucleotide changes of GJB2 gene. CONCLUSION The mtDNA 12SrRNA A1555G mutation has a high incidence in Chinese northwest population with non-syndromic sensorineural hearing loss.The 235delC mutation in the GJB2 gene is most frequent mutations responsible for non-syndromic hearing impairment in this region .It is unlikely that the GJB2 gene is a major modulatory factor for hearing loss due to the A1555G mutation in Chinese population.

OBJECTIVE: To explore the clinical features and genetic etiology of a child with Multiple congenital malformations-hypotonia-epilepsy syndrome type 3 (MCAHS3) and provide prenatal diagnosis for her parents. METHODS: A female child who had presented at Linyi People's Hospital on 27 July 2022 for recurrent convulsions for over 4 years was selected as the study subject. Clinical data of the child were collected. Peripheral blood samples were taken from the child and her parents and subjected for whole exome sequencing (WES). Candidate variants were verified by Sanger sequencing. Prenatal diagnosis was carried out on amniotic fluid sample at 18 weeks' gestation. Bioinformatic software was used to analyze the pathogenicity of the protein model for the variant loci. RESULTS: The child was a 4-year-old female with frequent seizures, peculiar facial appearance, hypotonia and severe developmental delay. Genetic analysis revealed that she has harbored compound heterozygous variants of the PIGT gene, namely c.1126del (p.H376Tfs*56) and c.1285G>C (p.E429Q), which were respectively inherited from her mother and father. Based on the guidelines from the American College of Medical Genetics and Genomics, the c.1126del (p.H376Tfs*56) variant was predicted to be pathogenic (PVS1+PM2_Supporting+PM4), and c.1285G>C (p.E429Q) variant was predicted to be likely pathogenic (PM2_Supporting+PM3+PM4). Prenatal diagnosis suggested that the fetus also harbored the same compound heterozygous variants, and the pregnancy was terminated with induced labor. CONCLUSION The c.1126del (p.H376Tfs*56) and c.1285G>C (p.E429Q) compound heterozygous variants of the PIGT gene probably underlay the MCAHS3 in this patient, and prenatal diagnosis has prevented birth of further affected child in this family.

Objective:To analyze the clinical phenotypes and TSC1/TSC2 gene variations in 52 children with tuberous sclerosis complex. Methods:The clinical data of 59 children with tuberous sclerosis complex hospitalized in Linyi People′s Hospital between January 2017 and October 2022 were collected. The analysis of TSC1 and TSC2 gene variations on main family members was performed, and then bioinformatics analysis followed. The positive children were divided into TSC1 gene group and TSC2 gene group, and the difference of clinical characteristics between the two groups was analyzed. Results:Among 59 children, 52 cases were detected TSC1/ TSC2 gene variations (17 cases in the TSC1 gene group and 35 cases in the TSC2 gene group). Of the 52 children, 28 (53.8%) were male, 24 were female (46.2%); 17 (32.7%) were familial cases (10 with TSC1 gene variations and 7 with TSC2 gene variations), 35 (67.3%) were sporadic cases; 46 (88.5%) had hypomelanotic macules, 13 (25.0%) had facial angiofibromas, 5 (9.6%) had shagreen patches, 49 (94.2%) had subependymal nodules/calcifications, 47 (90.4%) had cortical nodules, 2 (3.8%) had subependymal giant cell astrocytomas, 39 (75.0%) had intellectual/developmental disabilities, 49 (94.2%) had epileptic seizures, 8 (15.4%) had cardiac rhabdomyomas, 9 (17.3%) had renal angiomyolipomas, and 4 (7.7%) had retinal hamartomas. Of the 52 children, 49 variations were detected, including 4 large fragment deletion/duplication variations, and 45 point variations; 41 pathogenic variations, 7 likely pathogenic variations, and 1 variation of uncertain significance. In this study, 16 point mutations and 1 large fragment duplication mutation which had not been reported at home and abroad, and 3 high-frequency mutation sites (p.Arg692 *, p.Arg228 *, and p.Arg1200Try) were found. There was a statistically significant difference in the proportion of familial cases [10/17 vs 7/35(20%), χ2=7.838, P=0.005], median onset age of epilepsy [38.0(0.5-134.0) months vs 8.0(0.1-63.0) months, Z=3.506 , P<0.001] and the incidence of developmental retardation/intellectual impairment [8/17 vs 31/35(88.6%), χadj2=8.423, P=0.004] between the TSC1 gene and TSC2 gene groups. Conclusions:Tuberous sclerosis compiex has widespread phenotypes, can affect every body system, especially the skin and nervous system. The pathogenic gene is TSC1/ TSC2. The TSC1 gene group has more familial cases. The TSC2 gene group has an earlier onset age of epilepsy and a higher incidence of developmental retardation/intellectual impairment. In this study, 16 novel point mutations, 1 novel large fragment duplication mutation, and 3 hotspot mutations were identified, expanding the gene variation spectrum of tuberous sclerosis complex.
