Association between physical activity and exercise self-efficacy for adolescents with visual impairment / 中国康复理论与实践

ObjectiveTo investigate the association between physical activity (PA), sedentary level and exercise self-efficacy for adolescents with visual impairment, and impacts of gender, age, body mass index (BMI), degree of visual impairment and exercise self-efficacy on PA. MethodsFrom October to December, 2022, 79 students aged 13 to 18 years with visual impairment from Nanjing School for the Blind were measured PA and sedentary level with accelerometer. The average percentage of daily sedentary time (ST), light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) were recorded. The students fininshed the Exercise Self-Efficacy Questionnaire with the help of teachers, and their height and body mass was measured. ResultsThe average percentage of daily LPA, MVPA and ST was (15.45±5.99)%, (4.55±2.15)% and (80.00±6.99)%, respectively. Compared with the girls, the boys spent more time in LPA (F = 5.330, P < 0.05) and less in ST (F = 5.760, P < 0.05). Compared with students aged 16 to 18 years, those aged 13 to 15 years spent more time in MVPA (F = 11.292, P < 0.001) and less in ST (F = 8.279, P < 0.01). The score of exercise self-efficacy correlated with ST, LPA, MVPA and age (|r| > 0.254, P < 0.05). The result of multiple linear regression showed that the exercise self-efficacy (β = 0.224) and age (β = -0.495) were the independently factors related with MVPA, which explained 34.7% of MVPA variation. ConclusionAdolescents with visual impairment aged 13 to 18 years spend more time in sedentary, and their PA level is very low. Improvement of exercise self-efficacy may help to improve PA level of them.

Preparation and High-temperature Anti-adhesion Behavior of a Slippery Surface on Stainless Steel.

Anti-adhesion surfaces with high-temperature resistance have a wide application potential in electrosurgical instruments, engines, and pipelines. A typical anti-wetting superhydrophobic surface easily fails when exposed to a high-temperature liquid. Recently, Nepenthes-inspired slippery surfaces demonstrated a new way to solve the adhesion problem. A lubricant layer on the slippery surface can act as a barrier between the repelled materials and the surface structure. However, the slippery surfaces in previous studies rarely showed high-temperature resistance. Here, we describe a protocol for the preparation of slippery surfaces with high-temperature resistance. A photolithography-assisted method was used to fabricate pillar structures on stainless steel. By functionalizing the surface with saline, a slippery surface was prepared by adding silicone oil. The prepared slippery surface maintained the anti-wetting property for water, even when the surface was heated to 300 °C. Also, the slippery surface exhibited great anti-adhesion effects on soft tissues at high temperatures. This type of slippery surface on stainless steel has applications in medical devices, mechanical equipment, etc.

Epidemiological investigation of community-acquired methicillin resistant Staphylococcus aureus infection from 4 hospitals in Beijing / 中华检验医学杂志

ObjectiveTo investigate the prevalence,antibiotic characteristics as well as molecular background of community-associated methicillin-sensitive Staphylococcus aureus (CA-MRSA) from patients with skin and sofi tissue infections from 4 different hospitals in Beijing.MethodsFive hundred and one patients were enrolled from 4 hospitals prospectively.Patients with skin and soft tissue infections and no risk factors for healthcare-associated acquisition were included.Sample from the infection sites were collected for culture.Case report form was filled out for each patient.Antibiotic susceptibility test and molecular analysis was performed for each Staphylococcus aureus isolate.ResultsTotally 164 Staphylococcus aureus isolates were cultured from the patients with skin and soft tissue infections.Of them 5 isolates were CA-MRSA.These 5 CA-MRSA isolates harbored SCCmec Ⅰ, SCCmec Ⅲ, SCCmec Ⅳ,SCCmec Ⅴ and untypable,respectively.CA-MRSA was highly resistant to β-lactamase,levofloxacin,erythromycin and clindamycin,but susceptible to vancomycin,teicoplanin,linezolid,daptomycin,and trimethoprim/sulfamethoxazole.Prevalence of PVL in community-associated methicillin sensitive Staphylococcus aureus(CA-MSSA) and CA-MRSA were 41.9％ and 2/5.Other toxins expressed similarly between them.Combined with multilocus sequence typing (MLST) and spa typing,the major clones of CA-MSSA were ST398-t034,ST7-t796,ST398-t571,ST1t127,and ST188-t189,while in CA-MRSA were ST239-t037-SCCmec Ⅰ,ST239-t632-SCCmecⅢ,ST59-t437-SCCmecV,ST8-t008-SCCmecⅣ,and ST6-t701-NT.ConclusionsThe low prevalence of CA-MRSA in Beijing and complexity of the genetic background in CA-MRSA were observed.Clone spread is not found among CA-MRSAisolates.CA-MRSAexhibithigher resistancecomparedwithmethicillinsensitive Staphylococcus aureus (MSSA).Rational drug use scheme is called in the clinical practice to prevent development of high level resistance.

Blood coagulation disorder in acute pancreatitis of the elderly / 中国基层医药

Objective To explore the significance of blood coagulation disorder in acute pancreatitis(AP) of the elderly and its treatment with prostaglandin E_1.Methods Prothrombin time(PT),partially activated thromboplastin time(APTT) and fibrinogen(FIB) in cases of AP with ages over 60 were checked and compared with those in groups of AP with ages under 60 and normal control subjects.10 cases of AP of the elderly with elevated FIB were treated with prostaglandin E_1.Results Compared with groups of AP with ages under 60 and the normal subjects,FIB was significantly higher in cases of AP of the elderly with the highest in patients of SAP.8 out of 10 aged AP patients with elevated FIB was successfully treated with prostaglandin E_1.Conclusion Patients of AP may present with blood coagulation disorders especially in aged patients.Aged patients with elevated fibrinogen may predispose to SAP.Prostaglandin E_1 may be effective in this occasion.

Study on the corretation between serum HBV.M,alanine transaminase and hepatic tissue pathology in patients with chronic hepatitis B / 中国基层医药

Objective To investigate the relationship between serum HBV.M.alanine transaminase(ALT) and hepatic tissue pathology in patients with chronic hepatitis B.Methods The serum HBV.M.liver function in 133 patients with chronic hepatitis B were measured,and these patients underwent percutaneous liver biopsy by colour Echo.All these patients were divided into eight groups according to HBeAg and HBV DNA positive or negative,ALT normal or not.Hepatic necrosis inflammation grade and hepatic fibrosis stage in the groups were compared.Results Hepatic histology of all these patients showed inflammation and necrosis and different degree fibrosis.In serum ALT normal patients,liver biopsy still showed different degrees inflammation and hepatic fibrosis degrees partly,even showed hepatocirrhosis.In serum ALT abnormal and HBeAg negative patients with chronic hepatitis B patients,hepatic tissue inflammation and fibrosis degrees were more serious,hepatic tissue pathology was out of proportion to the degree of serum HBV reproduction.Conclusion Judgment of disease activity doesn't only depend on the serum transaminases and the degree of serum HBV DNA replication.When clinical choosing indication of antiviral therapy,value of liver biopsy should not be substituted.Liver biopsy in chronic hepatitis B should be regarded as main basis of judgment the hepatitis activity.It also should be regarded as main basis if antiviral therapy is conducted.
