OBJECTIVE: To observe the effect of Shenshuaining dispersible tablets on renal function of rats with chronic renal failure (CRF) induced by adenine and explore its action mechanism. METHODS: Seventy-two Sprague-Dawley rats (the ratio of male to female was 1∶1) were randomly divided into 6 groups: normal control group, model control group, Niaoduqing group, Shenshuaining dispersible tablets groups (high, middle and low doses). All groups except the normal control were fed with feed containing 0.5% adenine to estabish CRF model. After giving corresponding drugs for 7 weeks, the levels of nitric oxide (NO), total nitric oxide synthase (T-NOS), inducing nitric oxide synthase (iNOS), configuration nitric oxide synthase (cNOS), total superoxide dismutase (SOD), Cu/Zn-SOD and malonaldehyde (MDA) were detected. RESULTS: Compared with normal control group, the levels of NO,T-NOS, cNOS, T-SOD and Cu/Zn-SOD markedly decreased, and the iNOS and MDA contents were significantly increased in adenine-induced CRF rats. Shenshuaining dispersible tablets could markedly ameliorate the above indexes. CONCLUSION: Shenshuaining dispersible tablets could effectively ameliorate renal function. The mechanism might be related to the enhanced body's antioxidation abiliy, reduced damage of free radical and increased synthesis of cNOS and NO which possess protective effect on renal function.

1 or 2 grade FL followed by a diffuse large cell lymphoma(DLCL) ot a Burkitt/Burkitt-like lymphoma is TL.TL maintains a phenotype suggestive of germinal center derivation.The most common immunophenotype is the same as that of FL, CD+10/bcl-6+. Obtaining a biopsy of TL is enhanced if the biopsy is directed to the site with the greatest SUV. The risk of transformation of about 30% at 10 years after the initial diagnosis of FL.The median duration of survival after transformation generally ranging from 1 to 2 years.HDCT-ASCT, allogeneic tranplantation,radioimmunotherapy and bendamustine are the possible therapy for TL.

Objective To investigate the therapeutic potential of brain-derived neurotrophic factor (BDNF) and Schwann cells(SCs) in experimental autoimmune neuritis (EAN) and assess the effect and mechanism.Methods EAN model was established by immunization of Lewis rats with 400 μg of specific peptide P2(57-81)and complete Freund adjuvant.In the therapy group,the SCs (n =28) and the combination of BDNF administration and SCs (n =48) were labeled by the nuclear fluorescent dye injected into the intracerebroventricularly in 14 d after immunization.Transplanted cell migration tracking respectively were at 25,35 and 45 days after immunization.The rats were observed for signs of disease daily and subjected to clinical score,of which the sciatic nerves were subjected to histopathological examination (hematoxylin eosinstaining,luxol-fast-green and immunohistochemical staining).The inflammatory cell infiltration and demyelination were assessed,and the CD4,CD8,CD68,S-100 and nerve growth factor (NGF) positive cells numbers were compared among the 3 different groups.Results AIl the rats had the neurological deficits.Compared with control group,there were no significant differences in SCs therapy group.In SCs + BDNF therapy group,the recovery of paralytic symptom was faster and the score was lower after immunization 45 d.After immunization 25 and 35 days,both the inflammatory cells infiltration (EAN model group:325.8 ±10.8,221.4 ± 35.2;SCs + BDNF transplantation group:307.3 ±4.6,197.2 ± 16.8; t =2.172,P =0.031 ;t=3.756,P=0.000) and the expression of CD4+,CD8+ T cells and CD68+ macrophages were reduced.After immunization 35,45 days,the demyelination degree (EAN model group:3.4 ± 0.5,2.9 ± 0.8 ; SCs +BDNF transplantation group:2.9 ±0.8,2.3 ±0.5) was reduced (t =-7.408,P =0.000;t =-6.092,P =0.000),the expression of S-100 is higher,and NGF was lower than the control group in each time point after immunization.Conclusions SCs transplanted into the cerebellar ventricle of animals can migrate into the sciatic nerve.The combination of BDNF administration and SCs transplantation may represent an effective strategy by reducing inflammation reaction,improving the expression of S-100 in the donor cell,and reducing NGF irritability heighten in sciatic nerve.However,delivery of SCs alone is inefficiency to the treatment of EAN.

In the present work, Monte Carlo simulations were employed to study the characteristics of the dose distribution of high energy electron beam in the presence of uniform transverse magnetic field. The simulations carried out the transport processes of the 30 MeV electron beam in the homogeneous water phantom with different magnetic field. It was found that the dose distribution of the 30 MeV electron beam had changed significantly because of the magnetic field. The result showed that the range of the electron beam was decreased obviously and it formed a very high dose peak at the end of the range, and the ratio of maximum dose to the dose of the surface was greatly increased. The results of this study demonstrated that we could change the depth dose distribution of electron beam which is analogous to the heavy ion by modulating the energy of the electron and magnetic field. It means that using magnetic fields in conjunction with electron radiation therapy has great application prospect, but it also has brought new challenges for the research of dose algorithm.

Objective To evaluate the clinical effect of surgical operation for recovering the function of ulnar nerve with large segment defect. Methods Twentycases with the large segment defect of ulnar nerve were retrospectively analyzed from September 1999 to December 2006 in the hospital.All the patients were treated by the operation of nerve end-to-side neurorrhaphy . The broken end of ulnar nerve was anastomosed with the median nerve. And observed the recovery of the sensation and motion function of the little finger, interosseous muscles and claw hand, then compared with before. Results All cases were followed up for 8 to 36 months. The mean was 16 months. The sensation and motion function of the little fingers had better restoration after operation. No incision infection, anchylosis or myatrophy was occurred.Excellent(M4 + S4 +) ,Good (M3S3), moderate (M2S2), and poor effects (M1S1) were achieved respectively in 6, 4,2 and 0 cases based on the scale of XU' s grading standard.The excellent and good rate was 83.3%. Conclusion The nerve end-to-side neurorrhaphy was a effective treatment for the patients with large segment defect of ulnar nerve.

Objective The purpose of this study was to explore the impact of consistency primary nursing model on improvement of obstetric nursing care quality.Methods The sample consisted of 230 postpartum women in the intervention group and the other 240 postpartum women in the control group of non-intervention.The intervention is the use of new model of consistency primary nursing.Women finished the scale of overall patient satisfaction before their delivery.The other data of obstetric nursing care quality score were collected by study staff for three months.Data were analyzed using t test.Results Score of patients' overall satisfaction and obstetric nursing care quality in the invention group were much higher than that of the control group except for first-aid articles and disinfection and isolation.Conclusions The consistency primary nurs-ing model resulted in higher satisfaction and nursing care quality standard.It is suggested to extend this new nursing model in most maternity and infant hospitals and other general hospitals.
