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.

Objective To evaluate imaging diagnosis, differential diagnosis, surgery and interventional therapy of hepatic angiomyolipoma associated with tuberous sclerosis.Methods Clinical features, imaging appearances and interventional therapy for 2 cases of HAML in TS were retrospectrively analyzed. Results The features of HAML in TS are as following:(1) Two cases were female with no history of hepatitis and hepatocirrhosis, liver function test and alpha feto protein were normal. (2) the tumor was shown as a multiple hyperechoic mass with sharp margin on ultrasonography; well defined, fat density and intensity mass on computerized tomography (CT); hypervascular mass with early drainage of hepatic vein and tumor staining on angiography. (3) One case underwent interventional therapy. After 42 month follow up, the tumor was found to be diminished in size. Another case was under monitored with only the enucleating of left renal mass. The hepatic tumor showed no change after 10 months.Conclusions The imaging appearances of HAML in TS are relatively characteristic. Superselective arterial embolization is an effective treatment for HAML in TS.

Objective To explore the significance of perioperative management of percutanous laser lumbar disc decompression. Methods Retrospective analysis was carried out in 86 patients with lumbar disc herniation in order to evaluate the results of preoperative and postoperative managements. Results All patients passed through operative period safely. Total efficiency rate reach 78%(67/86). Conclusions It can be ensuring operative effect and decreasing the operative complication for the patients with lumbar disc herniation by intensifing the perioperative managment.

Objective To elucidate the characteristics of dermatosis in air force pilots and to improve its prevention and treatment scientifically. Method We carried out an investigation on 288 air force pilots hospitalized for dermatosis over the past 20 years. Results The results showed that 57.99% of the patients studied were admitted to hospital due to psychoimmunodermatosis, with high person-time (61.39%) and significantly longer average hospitalization time than that of the patients with the other two kinds of dermatoses. With improvement in flight skill and intensity as well as prolongation of flight time, the incidence and number of relapse of psychoimmunodermatosis in pilots were correspondingly increased. Conclusion The results indicate that among various dermatoses, psychoimmunodermatosis should become the focus of prevention and treatment as far as air force pilots are concerned. Besides drug treatment, we should also put emphasis on health education and psychological persuasion.
