The strategy for relocation of computer center room in hospital is expatiated.A set of measures are adopted such as careful planning,detailed design,aborative preparation,reasonable technique strategies,etc.The corresponding management system is established and.Finally,the computer center room is successfully relocated in one time without interruption of hospital information system.

Objective To understand the internal circuit contamination of ventilator in mechanical ventilation patients, to evaluate the effect of ventilator internal circuit disinfection and the impact on the incidence of ventilator-associated pneumonia (VAP). Methods A total of 39 patients with mechanical ventilation admitted to intensive care unit (ICU) of Hangzhou Geriatric Hospital from January 2017 to June 2018 were enrolled. Routine mechanical ventilation treatments for patients included pipeline replacement, aseptic operation, prevention of infection, etc. After 2 weeks of mechanical ventilation, the internal circuit of the ventilator was disinfected using the internal circuit sterilizer of the ventilator. Microorganism sampling and detection at 3 cm to the exhalation port of the internal circuit of the ventilator was performed before and after disinfection. The number of colonies was < 5 cfu/cm2 and no pathogenic bacteria could be detected. During the observation period, if the patient was complicated by VAP for anti-infective treatment, the ventilator with internal loop disinfection was replaced after infection control, and was incorporated again into the group for observation. The number of microbial colonies in the internal circuit of the ventilator before and after disinfection, the microbiological test pass rate and the incidences of VAP during the 2 weeks were observed. Results All 39 patients were included in the analysis, with 23 male and 16 female; with age of 65-97 years old, average (78.7±7.6) years old. Before the disinfection, 9 604 strains were detected in the internal circuit of the ventilator, including 8 687 strains of Gram-negative bacilli (90.4%), 902 strains of Gram-positive cocci (9.4%), and 15 strains of fungi (0.2%), which were detected in the lower respiratory tract of the patients. The strain concordance rate was 41%. The qualified rate of microbial detection in the internal circuit of the ventilator was 5.1%; 13 cases (33.3%) of VAP occurred during 2 weeks of mechanical ventilation. After disinfection, 785 strains of pathogens were detected in the internal circuit of the ventilator, and the number of colonies was significantly reduced compared with that before disinfection [cfu/cm2: 0 (0, 20) vs. 150 (15, 500), P < 0.01], of which 688 strains of Gram-negative bacilli (87.7%), 92 strains of Gram-positive cocci (11.7%) and 5 strains of fungi (0.6%) were found; the qualified rate of microbial detection in the internal circuit of ventilator reached 71.8%, which was significantly higher than that before disinfection (P < 0.01); 2 weeks after mechanical ventilation the incidence of VAP decreased slightly during the period [20.5% (8/39) vs. 33.3% (13/39)], but there was no significant difference (P > 0.05). Conclusions The internal circuit of the ventilator can be used to detect the pathogen and the sputum culture of the patients on mechanical ventilation with a high consistency. The disinfection of the pathogen could significantly reduce the air pollution of the ventilator and reduce the occurrence of VAP in the patients.

OBJECTIVETo detect FLG gene mutations in 10 families affected with ichthyosis vulgaris and to explore mutational hot spot of the FLG gene in Chinese Han population.

METHODSPCR and direct sequencing were carried out to identify potential mutations of the FLG gene in above families. One hundred healthy individuals were analyzed as normal controls.

RESULTSThree mutations (3321delA, 5757delCCAG and S2706X) were identified in 7 families. A homozygous mutation 3321delA was also detected in two unrelated patients. No mutations were found in the remaining three families. Neither of the null mutations (5757delCCAG and S2706X) was found in the 100 controls. However, for 3321delA, a heterozygous mutation was also found in two of the controls.

CONCLUSIONThree FLG mutations have been identified in the selected families with ichthyosis vulgaris, and the 3321delA mutation was most prevalent (46.9%). Mutations 5757delCCAG and S2706X were first found in patients with ichthyosis vulgaris. Other candidate genes may underlie the disease in those without a FLG mutation.

OBJECTIVETo detect mutations of ATP2A2 gene in a pedigree and a sporadic case with Darier disease (DD) and explore the underlying molecular mechanism.

METHODSClinical data of the pedigree and the sporadic case were collected. Genomic DNA was extracted from blood samples of four members from the pedigree (including three patients and one healthy member), the sporadic case and 100 healthy controls. PCR was performed to amplify all coding exons of the ATP2A2 gene. And the products were directly sequenced to detect mutations.

RESULTSA missense mutation c.1484C>T (p.S495L) in exon 12 was detected in all patients of the pedigree. For the sporadic case, a novel splicing mutation c.325-2A>G was detected at the junction between intron 4 and exon 5. The same mutations were not found in the 100 healthy controls.

CONCLUSIONMutations of the ATP2A2 gene may lead to the occurrence of DD in both familial and sporadic cases with DD.
