Blood dialysis is a long-term constant cure for imperfect chronic nephrosis, in which the water quality plays an important role. Since high purified water for blood dialysis is obtained by reverse osmosis film separation, the quality of reverse osmosis unit is critical for water quality index, which should meet AAMI water supply standard, thus entailing a proper plan for the whole system. In this paper, process design for reverse osmosis treatment, pretreatment and post-treatment system is presented.

The article put across Meta-analysis well by giving its definition and analyzing its development. It empha-sized its effect in the clinical medicine and dwelled on dealing with the problems encountered when meta-analysis wasapplied and the solutions to the problems. It also pointed out its significant role in raising the level of clinical medicine,teaching and scientific research.[

ObjectiveTo observe the clinical effect of occupational therapy (OT) on the function of upper limbs and complications in stroke patients with hemiplegia.Methods99 stroke patients were randomly divided into the OT group (52 cases treated with OT and routine rehabilitation) and control group (47 cases treated without OT). Fugl-Meyer Assessment (FMA) and evaluation of hand function were performed before and two months after treatment. The complications of patients in two groups were also compared.ResultsAfter treatment, the functions of upper limbs and hand of patients in the OT group were superior to those in the control group ( P<0.05). The numbers of cases with complications in the OT group were significantly less than that in the control group ( P <0.01).ConclusionOT can improve the functions of upper limbs and hand and abate complications in stroke patients.

The progression of liver fibrosis directly affects treatment options and prognosis.Early diagnosis and classification of liver fibrosis and dynamic monitoring are clinically needed.Noninvasive diagnostic techniques can avoid or reduce liver biopsy to enable early identifica-tion of liver fibrosis and to dynamically monitor the progression of fibrosis.But various limitations have restricted its application.Noninvasive diagnostic techniques,such as liver transient elastography using the different probe mode,controlled attenuation parameter,spleen stiffness measurement,ultrasound-based transient elastography for the early prediction of hepatic fibrosis,and risk assessment of hepatitis B virus-related hepatocellular carcinoma,have been applied in clinical studies.In order to better understand and apply these diagnostic models,the progress in clinical studies of noninvasive diagnosis of liver fibrosis,as well as the limitations,is reviewed.

ObjectiveTo explore the clinical role of island flap nourished by sural nerve nutrition blood vessel for repairing of the deep burn wounds of the lower extremities.MethodsIsland flap nourished by sural nerve nutrition blood vessel were performed to repair the deep burn wounds of the lower extremities below the knee in 22 cases,aged 10 ～58 years old,average aged 34 years old,including flame burns in 6 cases,electrical burns in 10 cases,chemical burns in 4 cases,scalding hot water in 2 cases.All were deep skin damage,The island flaps,including anterograde and retrograde flaps,was from 5cm ×4cm to 13cm × 10cm in size,The defect at the donor site was sutured primarily or repaired by a skin graft.ResultsAll the flaps survived well,18 patients were follow-up postoperatively for 4 ～24 months.The color,texture,shape of the flaps were satisfactory,but the sensory recovery was unsatisfactory.ConclusionSural neurovascular flap had a constant anatomy and reliable blood supply without the sacrificeof the major blood vessels.The procedure was simple and easy,and an effective method of repairing the skin and soft tissue defects below the knee.
