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.

The mechanism of damage in monocytes with the oxidation inhibitor α-lipoic acid (ALA) was observed under intermittent high glucose condition.The results showed that fluctuating high blood glucose levels led to more damage than that under constant high blood glucose level in monocyte,and antioxidant α-ALA could ameliorate the oxidative stress.The high level of nuclear factor-κB and monocyte chemotactic protein-1 are probably among the factors that cause vascular damage by deposit of monocytes.

AIM: To evaluate the safety and efficacy of loteprednol for controlling of ocular inflammation. METHODS: Data from 8 relevant monographs were retrieved by means of computerized and manual search. The combined analysis of the data was assessed in terms of clinical and statistical criteria, and the data were extracted and synthesized by using the statistical techniques of meta-analysis. Treatment effects and safety of loteprednol were through counting as risk difference between treatment and control groups. The estimates of pooled risk differences were computed according to a random-effects model. RESULTS: A total of 1 660 patients were included in this meta-analysis. Pooled risk differences of intraocular pressure elevation were 1 % (95 % CI, -1 %, 3 %) compared with placebo, -5 % (95 % CI, -9 %, 0 %) compared with prednisolone, respectively. Compared with placebo, pooled risk differences of inflammation improvement were: 31 % (95 % CI, 22 %, 40 %) of postoperative inflammation, 28 % (95 % CI, 19 %, 37 %) of seasonal allergic conjunctivitis, and 26 % (95 % CI, 18 %, 35 %) of giant papillary conjunctivitis, respectively. Compared with prednisolone, pooled risk differences of inflammation improvement of acute anterior uveitis was -15 % (95 % CI, -25 %, -4 %). CONCLUSION: Loteprednol is a safe and effective corticosteroid in controlling ocular inflammation such as postoperative inflammation, seasonal allergic conjunctivitis, giant papillary conjunctivitis, and acute anterior uveitis.

To investigate the expression of ICAM 1 and TNF ? in gastric mucosal cell during drug induced mucosal injury, the authors carried out the study in SD rats with aspirin by mouth with immunohistochemical method . The results showed that ICAM 1 began to express at 30min after administration of aspirin, peaked at 1h, maintained until 6h, decreased at 12h,and expressed slightly at 24h . TNF ? began to express at 15min, peaked at 3h to 6h,decreased at 12h, and expressed significantly at 24h. There was a slight ICAM 1 and TNF ? expression in gastric mucosal cells in the control group. It was suggested that the expression of ICAM 1 and TNF ? plays an important role in the mechanisms of gastric mucosal injury .
