A total of 60 brain injury patients with cognitive impairment were randomly divided into electro-acupuncture,computer and combination groups (n =20 each).The electro-acupuncture group received electroacupuncture,computer group cognitive rehabilitation training with specialized equipment and combination group both regimens.The treatment lasted for 2 months.Before training,Loewenstein occupational therapy cognitive assessment (LOTCA) test was not statistically significant among all groups (P 8 0.05).After 1 month,the combination group scored higher than pre-training (P ＜ 0.05).After 2 months,the scores of all groups were higher than pre-training(P ＜ 0.05).After 1 and 2-month training,the combination group scored higher than the other two groups in aspects of consciousness,optomotor tissue,attention,thinking and aggregate score (P ＜ 0.05).However,the orientation scores of all groups changed insignificantly after 1-month training (P 8 0.05),the combination group scored higher than the other two groups in improved orientation after 2 months (P ＜ 0.05).

Objective: Clinical study on Jangzhuo Decoction for treating plasma concentrations of oxidized low density lipoprotein, d dimer of ischemic stroke and its relation to preventing repeated stroke.Methods: 72 cases with ischemic stroke were divided randomly and blindly into two groups. 36 patients with ischemic stroke in therapeutic group were treated with Jangzhuo Decoction M ASA, and 36 patients in control group were treated with M ASA alone. The follow up survey for six months was conducted when physical signs and symptoms of the paints with ischemic stroke begain to be stable. Results: The incidence of the repeated stroke in therapeutic group were one case(2.7%) and in control group were three cases(8.3%) respectively. Ox LDL levels of therapeutic group was 1021?102?g/dl( ?s ), decreased to 604?77?g/dl( P 0.05). There was significant difference between the two groups. D dimer levels of two grouups were all increased significantly( P

Objective:To explore the action of the second signal system in the activatied and proliferating T cells and the induction of apoptosis of the hepatoma cells.Methods:The T cells were costimulated by anti CD28 and anti CD80(B7.1)McAb and acted on the hepatoma cells(BEL 7402),then testing the concentration of cAMP?cGMP and Ca 2+ in the T cells and the apoptosis of the hepatoma cells.Results:The concentration of cAMP was increased temporarily at first,then decreased rapidly,and increased 1 2 times again when acted on the hepatoma cells.The concentration of cGMP was increased 6 8 times fast and the concentration of Ca 2+ obviously increased 2 3 times too.The peak of them was at the fourth day and positive related to apoptosis of the hepatoma cells.Conclusion:The level of the second signal system of cAMP?cGMP and Ca 2+ were significant correlated with the T cells activated and porliferating and the cytotoxic effect.

Objective: To study the contents and constituents of LSPC (procyanidins from Lotus Seedpod) and its chemoprophylactic effects on 9,10-dimethyl-1,2-benzanthracene (DMBA)-induced golden hamsters buccal-pouch carcinomas. Methods: ESI-MS was used to analyze LSPC, and the change of body weight, mortality during test, and the value of serum MDA, GSH-Px, T-SOD,the gross and pathological change of buccal-pouch mucosa were investigated when golden hamsters were via gastric intubation or the buccal pouch mucosa was smeared with 100mg/(kg bw?d)LSPC. Results and conclusion: The contents of LSPC exceeded 98% and mono-, di-, tri-, tetrameric procyanidins as well as di-, trimeric galic ester were constituted of LSPC with molecular weight ranging from 290-1154. LSPC had chemoprophylactic effects on DMBA-induced golden hamsters buccal-pouch carcinomas, and the effect was superior through smearing LSPC rather then via gastric intubation .

A total of 60 patients with cognitive impairment were divided randomly into observation and control groups.Both groups were treated by conventional exercise therapy and computer-assisted cognitive rehabilitation while humanities therapy was combined in the observation group.After 8-week treatment,Loewenstein occupational therapy cognitive assessment (LOTCA) and modified Barthel index (MBI) scores were enhanced in both groups (P ＜ 0.05) while the scores of self-rating anxiety scale (SAS)and self-rating depression scale (SDS) declined obviously in observation group (P ＜ 0.05).The thought operation function,optomotor tissue,consciousness,concentration and total score of cognitive function in observation group were higher than control group (P ＜ 0.01) while the scores of SAS and SDS obviously lower (P ＜ 0.01).The scores of SAS were (50 ± 4),(55 ± 5) and SDS (53 ± 4),(56 ± 5) in two groups respectively.Therefore the therapy of computer cognitive rehabilitation plus humanities has the significant effect on improving cognitive function.

Objective To explore the relationship between plasma interleukin-11(sIL-11) level and platelet count post-chemotherapy with hematological malignancy patients and analyse a sIL-11 level which may maintain a safe platelet count so as to guide the treatment. Methods Blood samples were collected from the patients with hematological malignancy at certain time point of pre-and post-chemotherapy, and serum level of sIL-11 and platelet count were determined separately. Different statistical methods were applied to test the relationship between sIL-11 level and platelet changes. Results 99 cases finished this study. The findings are: the sIL-11 level went up and reached the peak on day 6 post-chemotherapy, while the platelet count kept dropping to the lowest on day 10, the sIL-11 peak occurred before the lowest platelet count, patients with faster sIL-11 increase may maintain a comparatively higher plateled count. 99 eases were grouped according to the lowest platelet count and compared: the group with higher platelet count tend to have higher peak sIL-11, more cases with higher peak sIL-11, with faster daily average sIL-11 increase, the lowest platelet count occurred later. Logistic regression analysis showed the factors contributed to lower platelet includes slower daily average sIL-11 increase and sIL-11 level less than 2000 pg/ml on Day4 post-chemotherapy. Conclusion There were correlation between the serum sIL-11 level and platelet counts, the platelet count change may be predicted by determining the plasma sIL-11 level post-chemotherapy. Patients with sIL-11 level less than 2000 pg/ml on Day4 post-chemotherapy may be endangered with severe thrombocytopenia, rhIL-11 or platelet transfusion treatment should be considered.
