Objective To investigate the factors influencing basic rehabilitation service needs of people with disability at Zhabei District in Shanghai .Methods Primary rehabilitation demands and services of 10 311 disabled persons in Zhabei District were surveyed.Results The screening rate of persons with disability having primary rehabilitation demands was 83.5%. And the gender, age, type of disability, disability level, education, employment might be the factors affecting the primary rehabilitation demands of people with disability.Conclusion The primary rehabilitation service demands vary in deferent types of people with disability. The various services based on the extensive rehabilitation services should be provided to deferent categories of people with disability.

Objective To understand the status of special rehabilitation service demands of people with disability at Zhabei District in Shanghai and to provide the basis for the policy development.Methods Screen rate (SR) was used to indicate the level of demand of rehabilitation service, the data were analyzed with SPSS 13.0 statistical software.Results There were 4 349 persons with disability who demanded the special rehabilitation service; the SR of “on-site rehabilitation service” demands was the highest among the whole persons with disability; the SR of “personalized allotment of supplies and appliances” demands of the intellectual disability and mental disability was lower than the other types; the SR of special rehabilitation service demands of the female, the elderly, the low cultural level, the unemployed and the people with severe disability were relatively higher.Conclusion The form of “on-site rehabilitation services” needs to improve based on the demand of the disabilities; “personalized supplies and appliances” for the intellectual disability and mental disability needs to further develop; the rehabilitation services targeted to the female, the elderly, the low cultural level, the unemployed and the people with severe disability need to improve.

Objective To provide the advice on how to optimize the allocation of resources and make other policy through the analysis factors affecting rehabilitation services needs of people with disability at Zhabei district in Shanghai.Methods The factors affecting rehabilitation services needs such as types of disability, disability levels, education, employment, marital status, age and sex were analyzed with Logistic analysis.Results The factors affecting primary rehabilitation services were types of disability, education, employment situation, marital status and sex. And people with disability had the characters of female, hearing disability, retired returned to more primary rehabilitation services, with OR values being 1.219, 1.544 and 1.533 respectively compared with itself controls. And the high educational disable people' will, returning to primary rehabilitation services, was weaker compared with low educational disable people. The factors affecting special rehabilitation services were types of disability and employment situation. And people with disability had the characters of hearing disability, unemployment returned to more special rehabilitation services, with OR values being 2.380 and 1.310 respectively compared with itself controls.Conclusion The rehabilitation needs are different among different groups people with disability, so the factors affecting rehabilitation services needs such as types of disability, education, employment situation, marital status and sex should be taken into consideration while activating primary rehabilitation services, while the types of disability and employment situation should be taken into more consideration while activating special rehabilitation services.

Abstract： Objective　To investigate the distribution and antimicrobial resistance profile of the bacterial strains isolated from blood cultures in neonatal septicemia children of Neonatology Department, the First People's Hospital of Chuzhou during Jan. 2017-Dec. 2021, in order to guide clinical rational drug use. Methods　The distribution and the results of antimicrobial susceptibility tests and characteristics of the pathogenic bacteria isolated from blood culture samples in neonatal septicemia children in the First Hospital of Chuzhou from Jan. 2017 to Dec. 2021 were retrospectively analyzed. The results were analyzed with WHONET 5.6 software, according to the Clinical and Laboratory Standards Institute (CLSI) 2021 breakpoints. 　Results　A total of 189 strains were isolated from the 4 538 sample of blood cultures, the positive rate was 4.2%, including 59(31.2%) Gram-negative bacterial strains, 130 (68.8%) Gram-positive bacterial strains. The most frequently isolates were coagulase-negative staphylococci（64.0%), Serratia liquefaciens (15.9%), Escherichia coli (3.2%), Acinetobacter lwoffii (2.6%) and Delftia acidovorans (2.6%). The prevalence of methicillin-resistant isolates was 81.8%(99/121) in coagulase-negative Staphylococci and 25.0%（1/4） in Staphylococcus aureus. No staphylococcal strains were found resistant to vancomycin, quinupristin-dalfopristin or linezolid. The sensitivity of the antibacterial drug monitored by Serratia liquefaciens was 100.0%.Conclusions　Gram-positive bacterial are the main pathogen of neonatal septicemia, and is highly resistant to the common antibacterial drugs.

BACKGROUND:Currently, cellular composition and the features of the nucleus pulposus are stil not to be clarified.
OBJECTIVE:To establish the in vitro culture system of rat nucleus pulposus-derived mesenchymal stem cells and to identify their multi-lineage differentiation potential.
METHODS:Mesenchymal stem cells from the nucleus pulposus tissues of Sprague-Dawley rats were cultured in vitro. Then, cells at passage 3 were induced to differentiate into osteoblasts, adipocytes and chondrocytes as experimental group. cells cultured with basic culture medium served as controls.
RESULTS AND CONCLUSION:cells isolated from rat nucleus pulposus could form the sunflower-like colonies and exhibit clone-like growth when they cultured at a low density. cells at passage 3 became homogeneous and exhibited fibroblast-like morphology. After 28 days of osteogenic induction, arizarin red positive signals were detected in the experimental group. The mRNA expressions of RunX2, osteopontin and osteocalcin were significantly increased in the experimental group, compared to the control group (P<0.05). After 21 days of adipogenic induction, oil red-O positive cells were detected in the experimental group. The mRNA expressions of C/EBPαand PPARγ2 were significantly increased in the experimental group, compared to the control group (P<0.05). After 21 days of chondrogenic induction, safranin O/fast green staining was positive in the experimental group. The mRNA expressions of aggrecan and Col2a1 were significantly increased in the experimental group, compared to the control group (P<0.05). Our findings in this study suggested that nucleus pulposus-derived mesenchymal stem cells could be isolated from the Sprague-Dawley rat nucleus pulposus and exhibited clonal-like growth when they were cultured in vitro. These cells were confirmed to have the potential to differentiate into adipocytes, osteoblasts and chondrocytes in vitro.

BACKGROUND:Previous studies have suggested that the risks for coronary atherosclerotic plaque progression and in-stent restenosis are increased in patients with coronary heart disease combined with type 2 diabetes. OBJECTIVE:To explore the predictive factors for in-stent late loss and non-culprit coronary lesion progression in patients with type 2 diabetes mel itus. METHODS:A total of 399 stenting patients were enrol ed, including 179 diabetic patients and 220 non-diabetic patients. The clinical materials, angiography parameters and biochemical markers were col ected. The difference between the two groups was compared, and also we conducted subgroup analysis in the diabetic patients. Low-density lipoprotein cholesterol, hemoglobin A1c, fibrinogen and high-sensitivity C-reactive protein were detected at days 3, 120, 210 and 360 after stenting. RESULTS AND CONCLUSION:Compared with non-diabetic patients, the stent length (P=0.18) was longer and the stent diameter (P=0.002) was smal er in the diabetic patients. The minimal lumen diameters of post-procedure and fol ow-up angiography in the diabetic group were significantly decreased (P=0.001, P=0), and the diabetic patients also showed severe coronary artery stenosis instantly and within the fol ow-up after stenting (P=0.038, P=0.004). The fol ow-up angiography showed that the diabetic patients had more late loss and restenosis (P=0, P=0.097). Furthermore, in the subgroup analysis of diabetic patients, the levels of hemoglobin A1c, fibrinogen and high-sensitivity C-reactive protein were significantly increased in the patients with restenosis and non-culprit lesion progression. These findings indicate that diabetic patients appear to have the higher incidence of restenosis and non-culprit lesion progression. Moreover, hemoglobin A1c, fibrinogen and high-sensitivity C-reactive protein are effective predictors for in-stent late loss and non-culprit coronary lesion progression.

Objective:To evaluate the application value of bismuth shielding combined with organ tube current modulation (X-care) in brain CT scanning by measuring the radiation dose of sensitive organs.Methods:The head and neck phantom was scanned with Siemens dual source CT at the same volume CT dose index (CTDI vol) by X-care, bismuth shielding and x-care combined with bismuth shielding, and by dual energy CT angiography (DE-CTA) with and without bismuth shielding. The CT values of cerebral vessels, adjacent brain tissues and cerebrospinal fluid and image noise were measured, and the contrast noise ratio of cerebral vessels and brain parenchyma was calculated. Organ dose equivalent ( HT) was calculated by placing thermoluminescent personal dosimeter (TLD), and CTDI vol and dose length product (DLP) were recorded after each scan. Results:Under the same CTDI vol, the mean values of HT, lens with X-care, Bi shielding and X-care combined with Bi shielding were(37.89 ± 2.00), (42.20 ± 2.96) and (28.21 ± 1.31) mSv, respectively, significantly lower than those of conventional sequence scanning( F=186.52, P<0.05). The values of HT, thyroid with Bi shielding and X-care combined with Bi shielding were (0.77 ± 0.07) and (0.89 ± 0.08) mSv, lower than those of routine brain scan and X-care( F=103.26, P<0.05). The values of HT, lens and HT, thyroidof DE-CTA with bismuth shielding were (11.56 ± 1.04) and (0.32 ± 0.03) mSv, respectively, significantly lower than those without bismuth shielding( t=5.07, P<0.05). There was no significant difference in noise and CNR in routine brain scan between with and without X-care, bismuth shielding and X-care combined with bismuth shielding. There was no significant difference in noise and CNR in dual energy CTA scanning between with and without Bi shielding. Conclusions:Using bismuth shielding and organ tube current modulation, we can significantly reduce organ dose of lens and thyroid during brain CT scanning without sacrificing the image quality.

BACKGROUND: Data on the mechanical ventilation (MV) characteristics and radiologic features for the cases with H7N9-induced ARDS were stil lacking. METHODS: We describe the MV characteristics and radiologic features of adult patients with ARDS due to microbiologically confirmed H7N9 admitted to our ICU over a 3-month period. RESULTS: Eight patients (mean age 57.38±16.75; 5 male) were diagnosed with H7N9 in the first quarter of 2014. All developed respiratory failure complicated by acute respiratory distress syndrome (ARDS), which required MV in ICU. The baseline APACHE II and SOFA score was 11.77±6.32 and 7.71±3.12. The overall CT scores of the patients was 247.68±34.28 and the range of CT scores was 196.3–294.7. The average MV days was 14.63±6.14, and 4 patients required additional rescue therapies for refractory hypoxemia. Despite these measures, 3 patients died. CONCLUSION: In H7N9-infected patients with ARDS, low tidal volume strategy was the conventional mode. RM as one of rescue therapies to refractory hypoxemia in these patients with serious architectural distortion and high CT scores, which could cause further lung damage, may induce bad outcomes and requires serious consideration. Prone ventilation may improve mortality, and should be performed at the early stage of the disease, not as a rescue therapy.
