OBJECTIVE:To probe into the optimum condition and dosage of activated carbon in the preparation of arilin injection.METHODS:The impacts of activated carbon of different dosage at different temperature,different storage time and different pH value of preparation on the contents of arilin injection were investigated and analyzed statistically.RESULTS:Positive correlation was found between the descending degree of the contents of arilin and the dosage of the activated carbon(P

Autophagy is a dynamic process which subcellular membranes undergo morphological changes that lead to the degradation of cellular cytoplasmic organelles and macromolecules.It is regulated by themammalian target of rapamycin ( mTOR ) -dependent or -independent signaling pathways.It has been demonstrated that autophagy is induced or inhibited in various tumor cells,and it is closely related with cell survival and drug resistance.Because of the complex relationships with cell death,the roles of autophagy in cancer developnent,treatment,and drug-resistance are not the same,and thus controlling autophagy properly may become one of new means of cancer therapy.

Objective To evaluate the efleet of continuous subcutaneous insulin infusion (CSII)combined with mefformin hydroehloride( Met H)on type 2 diabetic patients. Methods 240 patients with type 2 diabetes melli-tus (T2DM) were divided into 3 groups randomly: CSII combined with Met H ( A group: n=80) ; simple CSII ( B group:n=80) ; multiple deliver insulin (MDI) ( C group: n=80). The levels of blood glucose, HbA1 e, therapeutic time, a-mount of insulin, Fins ,C-P, HOMA-IR and IAI were compared among them before and after 10d of treatment. Results GroupA, B eornpared with group C, the levels of HbA1 e significantly deeroased in other two groups [ ( 8.0±3.2)%vs. (6.9±1.4)% and(7.0±1.2)% ] (aU P<0.05),so did the therapeutic time[(6.0±1.9)d vs. (3.0±1.4) and(3.5±1.5) d] and insulin dose[ (55.0±17.0) U/d vs. (38.0±15.0) U/d and(45.0±16) U/d] (all P<0.05). The insulin dose was much less in group A than in group B. Versus group B and C,the HOMA-IR of group A (0.8±0.3 vs. 1.5±0.4 and 1.6±0.4)decreased(P<0.05) ,and IAI(-2.0±4.3 vs. -3.6±4. 2 and -4.1±4.3) increased (all P<0.05), without the function impairments of heart, liver or kidney. Conclusion CSII in combi-nation with mefformin hydreehloride can significantly enhance the treatment effect of the patients with type 2 diabetes mellitns; reduce blood glucose and HbA1 e, improve insulin resistenee,lessen insulin need.

Objective To explore the application value of susceptibility weighted imaging (SWD) in the Parkinson disease (PD) diagnosis by analysis the changes of brain iron content of the basal ganglia and red nucleus.Methods Totally 56 cases of patients with PD and 40 cases of normal control group were diagnosed by SWI with the 3.0 T magnetic resonance imaging system,the corresponding phase image by using SWI processing software was obtained,the signal values of the various regions of the brain basal ganglia and red nucleus were measured and compared.Results In comparison of PD group with normal control group,the signal values showed differences in caudate (0.05±0.01 vs.0.04±0.01,t=1.991),putamen(-0.42±0.13 vs.-0.25±0.07,t=2.544) and globus pallidus(-0.23± 0.07 vs.-0.11±0.02,t=2.893) (all P＜0.05).Conclusions Determining the iron deposition signal of the various regions of the brain basal ganglia by SWI is valuable in the clinical diagnosis of Parkinson's disease.

Most patients with allergic conjunctivitis in children are vernal keratoconjunctivitis.Dry eye accompanied with al- lergic conjunctivitis in children is correlated with the decline of tear film stability.However,tear film stability decline is correlated with eosinophilic activation and concomitant release of inflammatory mediators.Moreover,conjunctival epithelial,goblet cells and tear film are damaged,then dry eye occur.Main symptom of dry eye in children is twinkling frequency increasing,followed by eye itch,eye red and photophobia.When allergic conjunctivitis in children is diagnosed,dry eye should be considered at the same time.Proper manage- ment for those allergic conjunctivitis can decrease ocular surface damages.

Objective To investigate the efficacy and safety of polyethersulfone highlux dialyzer for maintenance hemodialysis patients. Methods Thirty-six maintenance hemodialysis patients were randomizedresigned into two groups,polyethersulfone 14HF(PES-14HF)group and polyethersulfone 150DS(PES-150DS)group,based on a random number table. The patients from two groups received different dialyzer hemodialysis for over 3.5 hours/each time respectively. Changes of serum creatinine,urea,β2-microglobulin,hemoglobin and albumin levels were measured for determination of the efficacy and safety evaluation. Results In the comparison between before or after hemodialysis,the level of serum creatinine,urea,β2-microglobulin levels decreased significantly to(333.8 ± 89. 5)μmol/L,(7. 0 ± 1.9)mmol/L,(22. 9 ± 1.7)mmol/L from(990. 2 ± 191.2)μmol/L,(24. 7 ± 4. 1)mmol/L,(13.6 ± 3.3)mmol/L respectively in the PES1 4 HF group(P ＜ 0.01);the level of serum creatinine,urea,β2-microglobulin levels decreased significantly to(395.5 ± 86.1)μmol/L,(8. 1± 2. 8)mnol/L,(18.0 ± 3.0)mmol/L from(1059. 5 ± 179. 4)μmol/L,(25.3 ± 4. 8)mmol/L,(22. 3 ± 2. 9)mmol/L respectively in the PES-150DS group(P ＜ 0. 01). We found no significant differences in each measured index between two types of hemodialysis(P ＞ 0. 05 respectively),while the level of β2 -microglobulin levels decreased more significantly in the PES14HF group(42. 81 ± 12. 48)mg/L than PES-150DS group(24. 21 ± 13. 24)mg/L(P =0. 017). Conclusions The efficacy and safety of the PES-14HF hollow fiber membrane hemodialyzer is equivalent to that of the PES-150DS hemodialyzer in hemodialysis for uremic patients.

The molecular and cellular mechanisms of bone metastasis in prostate cancer remain unclear. Current researches focus on chemotaxis of tumor cells in bone metastasis, interactions between tumor cells and bone micro-environment as well as the vicious circle among tumor cells, osteoclasts, osteoblasts and bone matrix.

Scaffold is one of the key elements required for tissue engineering. Porous scaffolds have several special advantages for muscle tissue engineering, and they are beneficial to cell survival, myogenic differentiation, and vascular ingrowth. The performance of porous scaffolds is closely related to the property of the biomaterials used. Additionally, the pore size and porosity may affect cell adhesion, proliferation, and differentiation. This review focuses on the application of porous scaffolds in muscle tissue engineering, including their categories, application, and advantages.
