Chinese Journal of Practical Internal Medicine 2002;0(08):-
Objective To evaluate the anti-oxidant effects of vitamin E -modified membrane in hemodialysis patients.Methods In our four-week study,57 patients on maintenance hemodialysis were divided randomly into three groups.Group A (n=19) resorted to hemodialysis with VitE-modified membrane;Group B (n=19) resorted to hemodialysis with conventional dialyzers and oral VitE intake(400mg/d);Group C (n=19) resorted to hemodialysis with neither vitamin E-modified membrane nor vitamin E intake.Blood samples were collected prior to the first and thirteenth dialysis sessions,and were employed to determine the concentrations of malonylaldehyde (MDA),glutathione peroxidease (GSH-px),glutathione (GSH),superoxide dismutase (SOD) and Vitamin E in plasma and red blood cells (RBC),and advanced oxidative protein products (AOPP) in plasma.Results In group A,there were significant increase in VitE,GSH-px,GSH and SOD levels,and declined MDA and AOPP levels in plasma and in RBC(P0.05).Conclusion Our study suggests that VitE may have anti-oxidant effects on hemodialysis patients,and that VitE-modified membrane may have more advantages in anti-oxidative effect compared with.VitE oral administration.
2.Problems of rituximab as the targeting therapy for non-Hodgkin lymphoma
Journal of Leukemia & Lymphoma 2008;17(4):312-315
Ten years had passed for the molecular targeted therapy since approval by the U.S.Food and Drug Administration of the first monoclonal antibody-Rituximab,for the treatment of the B-cell non-Hodgkin's lymphomas with positive CD20- The targeting therapy,which may be a promising approach in the future,has significantly improved the patients'qualities of lives and prognosis because it has higher selectivity and less adverse effects than current chemotherapy and radiotherapy.In the past decade,with the fast development of novel targeting drugs and extension of therapeutic fields,the limitations associated with the targeted treatments were received attentions.

OBJECTIVE:
To study the therapeutic effects of the specific immunotherapy (SIT) on allergic rhinitis and allergic rhinitis combined bronchial asthma. METHED: All patients were classified into allergic rhinitis group (AR group) with 32 patients and allergic rhinitis combined bronchial asthma group (AR+BA group) with 32 patients. Another health control group with 32 cases was designed as well. The allergens,symptom scores and therapeutic effects of the former two-group patients were analysis, and the serums of all three-group cases were extracted to evaluate the specific Immunoglobin E(sIgE), Interleukin-4 (IL-4). The SPSS13. 0 package was applied to conduct t-test and chi-square test, and the difference of P<0. 05 was regarded as statistical significance.
RESULT:
The main allergens of 64 patients were dermatophagoides farinae and dermatophagoides pteronyssinus. The improvement of symptom scores before and after SIT was statistical significant with P<0. 05. Although total effective rate reached 100% , AR group was superior than AR+BA group in term of the efficacy comparison, and P<0. 05 indicated the statistical significance. The serum sIgE, IL-4 values of three groups were brought into comparison, and P<0. 05 indicated the statistical significance of the difference.
CONCLUSION
The SIT on the AR, AR+BA is a safe and effective treatment, but different disease responds diversely. The long-term treatment course is recommended.

Objective: To explore the dignositic characteristics of coronary heart disease (CHD) in perimenopausal women. Methods: The clinical data of 180 patients suspected of CHD were retrospectively analyzed. The risk factors of CHD,clinical characteristics of chest pain, routine electrocardiography,ambulatory electrocardiography and coronary artery angiography (CAA) were compared between perimenopause group and control group. Results: The incidence of CHD increased significantly in control group(13.5%, 10/76) compared to perimenopause group (43.3%, 45/104, P

Objective To analyze the cases of anaphylactic death cases and explore the standards of judi-cial expertise of anaphylactic death for providing evidence for judicial expertise. Methods Fifty-nine cas-es death due to allergic reaction in Shanghai were collected. And details of medical history, clinical manifestation of anaphylactic reaction and postm ortem exam ination findings were review ed for all cases. Results In the 59 cases, there were 58 cases died from drug allergy, including 77.6% of them were an-tibiotics. The rates of treating in standard hospital and illegal clinic were 37.3% and 61.0%, respectively. The allergic sym ptom s were dyspnea and facial cyanosis. The time from contacting allergens to death ranged from 1 m in to 3 d. The concentration of total serum IgE ranged from 50 to 576.92 IU/m L . The results of clinical manifestation and pathological anatomy had obviously changes. Conclusion B ased on the exclusion of all other cause of death and synthetically analysis of details of cases, medical history, clinical manifestation and anatomy, the conclusion of anaphylactic death can reached. The details of cas-es including clinical history, exposure to allergens, and clinical manifestation play an im portant role in diagnosis of anaphylactic death.

Objective To examine the effect of father parenting stress and paternal marital satisfaction on father involvement,and to explore the mediating role of maternal perceptions of father involvement in father involvement and maternal marital satisfaction.Methods 300 children's fathers and mothers from 5 kindergartens in Beijing city,Dezhou city,Wuhu city were surveyed with the Chinese version of the PSI/SF,the father involvement questionnaire and the marital satisfaction questionnaire.Results The score of paternal marital satisfaction was (3.98±0.75),(3.84±0.76) for maternal marital satisfaction,(2.26±0.50) for father parenting stress,(2.60±0.49) for father involvement,(2.50±0.50) for maternal perceptions of father involvement.Correlation analysis showed that father parenting stress was negatively correlated with father involvement(r=-0.36,P<0.01),paternal marital satisfaction was positively correlated with father involvement (r=0.33,P<0.01),father involvement was positively correlated with maternal marital satisfaction(r=0.36,P <0.01),father involvement was positively correlated with maternal perceptions of father involvement (r=0.48,P<0.01).A structure equation model consisting of father parenting stress,father involvement and marital satisfaction had a better degree of fitting:GFI =0.99,NFI =0.99,CFI =0.99,RMSEA<0.001.Maternal perceptions of father involvement mediated the effect of father involvement on maternal marital satisfaction (effect value:0.41,P<0.05).Conclusion Father parenting stress and paternal marital satisfaction could significantly predict father involvement,father involvement could significantly predict maternal marital satisfaction.These studies verified the spillover effect and the crossover effect between spousal subsystem and parental subsystem.

Objective To explore the relationship between the expression of EIIIA + fibronectin in incised wound of rat’s skin and injury time. Methods The wounding model was established by cutting the dor-salskin of 48 adult SD rats. The rats were sacrificed atthe pre-setinjury time as immediately, 0. 5h, 1h, 2 h, 3 h, 4 h, 6 h, and 8 h. The skin sam ples were taken at the m argin of wound. The expression of the EIIIA + fibronectin was detected by im m unohistochem istry and W estern blotting and the relationship be-tween its expression and injury time was observed. Results The expression of EIIIA + fibronectin was not observed im m ediately. The basal cell of skin began to showpositive expression 0. 5 h after injury. W ith the extension of injury time, positive staining became stronger. The value of relative optical density was gradually increased with prolonged injury time by the W estern blotting analysis. Conclusion The expres-sion of EIIIA + fibronectin could be used for estimation of injury time in the early stage of skin injury.
