Chinese Journal of Rehabilitation Theory and Practice 2006;12(12):1093-1094
Objective To observe the effect of motor relearning program (MRP) on balance function of stroke patients.Methods Sixty stroke patients were randomly divided into the MRP group and control group with 30 cases in each group. The patients of the control group were trained with proprioceptive neuromuscular facilitation (PNF) therapy; those of the MRP group were trained with the MRP therapy. The balance function of all patients was assessed with the Fugl-Meyer Balance Function Assessment before and after training.Results After training, the scores of Fugl-Meyer Assessment of all patients increased ( P<0.05), but scores of the patients of the MRP group were significantly higher than that of the control group ( P<0.05).Conclusion The MRP training can improve the recovery of balance function of stroke patients.

OBJECTIVETo investigate the effect of Chinese medicine (CM) Schisandra chinensis on interleukin (IL), glucose metabolism, and pituitary-adrenal and gonadal axis of rats after strenuous navigation and exercise.
METHODSA total of 45 Sprague-Dawley rats were randomized into the quiet control group, the stress group, and the CM group (15 in each group). The CM group received 2.5 g/kg of Schisandra chinensis twice per day for one week before modeling. Except the quiet controls, rats were trained using the Bedford mode for 10 days. On the 11th day, they performed 3 h of stressful experimental navigation and 3 h of strenuous treadmill exercise. The levels of serum testosterone (T), cortisol (CORT), luteinizing hormone (LH), IL-1, IL-2, and IL-6 were tested by radioimmunoassay and enzyme-linked immunosorbent assay, respectively. The adrenal cortex ultrastructure was observed using electron microscopy.
RESULTSCompared with the quiet control group, after navigation and strenuous exercise, blood glucose was increased, and T level was decreased in the stress group (both P<0.01). The blood glucose, CORT, IL-1 and IL-2 levels were significantly reduced in the CM group (P<0.05 or P<0.01) as compared with the stress group. Electron microscopy revealed that the rats in the CM group had a smaller decrease in adrenal intracellular lipid droplets and higher levels of apoptosis than those in the stress group.
CONCLUSIONSSchisandra chinensis can reduce serum CORT and blood glucose levels in stressed rats. It appears to protect the cell structure of the adrenal cortex, and offset the negative effects of psychological stress and strenuous exercise related to immune dysfunction. Schisandra chinensis plays a regulatory role in immune function, and can decrease the influence of stress in rats.

PURPOSE: The characteristic expression of DNA damage response proteins in familial breast cancers with BRCA1, BRCA2, or non-BRCA1/2 mutations has not been analyzed in Chinese patients. Our study aimed to assess the differential expression of microcephalin 1 (BRIT1), ATM serine/threonine kinase (ATM), checkpoint kinase 2 (CHEK2), BRCA1, RAD51 recombinase (RAD51), and poly (ADP-ribose) polymerase 1 (PARP-1) and establish the profile of Chinese familial breast cancers with different mutation status. METHODS: We constructed five tissue microarrays from 183 familial breast cancer patients (31 with BRCA1 mutations; 14 with BRCA2 mutations, and 138 with non-BRCA1/2 mutations). The DNA response and repair markers used for immunohistochemistry analysis included BRIT1, ATM, CHEK2, BRCA1, RAD51, and PARP-1. The expressions of these proteins were analyzed in BRCA1/2 mutated tumors. The association between pathologic characteristics with BRCA1/2 mutation status was also analyzed. RESULTS: In familial breast cancer patients, BRCA1 mutated tumors were more frequent with high nuclear grade, estrogen receptor/progesterone receptor/human epidermal growth factor receptor 2 negative, low Ki-67, and positive CK5/6. BRCA1 mutated tumors had lower CHEK2 and higher cytoplasmic BRIT1 expression than BRCA2 and non-BRCA1/2 mutation tumors. BRCA2-associated tumors showed higher CHEK2 and cytoplasmic RAD51 expression than those in other groups. Nuclear PARP-1 expression in BRCA1/2-associated tumors was significantly higher than in non-BRCA1/2 mutation tumors. Moreover, we found quite a few of negative PARP-1 expression cases in BRCA1/2 mutated groups. CONCLUSION: The clinicopathologic findings of BRCA1-associated Chinese familial breast cancers were similar to the results of other studies. Chinese familial breast cancer patients with BRCA1/2 mutations might have distinctive expression of different DNA damage response proteins. The reduced expression of PARP-1 in Chinese BRCA1/2 mutated breast cancer patients could influence the therapeutic outcome of PARP-1 inhibitors.

To investigate the role of CD4+, CD25+, and CD127low regulatory T cells (Tregs) in multiple myeloma (MM). Methods:Levels of CD4+T cells and Tregs, as well as expression of CTLA-4 and apoptosis-related proteins, such as CD95, bcl-2, and Caspase3 of Tregs in peripheral blood of 30 patients with newly diagnosed cases, 27 patients under of complete remission (CR) from multiple myeloma patients, and 25 healthy adults were analyzed by flow cytometry. Results:The percentage of CD4+T cells in the untreated group was significantly lower than that of the control group (P<0.05). The percentage of Tregs in CD4+T cells in the untreated group was significantly higher than that of the CR group and control group (P<0.05), which in ISSⅢpatients of the untreated group was significantly higher than that in I/II(P<0.05). No significant difference of CD95 expression in Tregs was observed among the three groups. The expression of CTLA-4 in Tregs from the untreated group was significantly higher than that of the CR group (P<0.05) and control group (P<0.01), and so was in CR group than this in controls (P<0.05). The expression of bcl-2 in Tregs in the untreated group was significantly higher than that of the CR group (P<0.05) and control group (P<0.01), and so was in CR group than this in controls(P<0.05). The expression of Caspase3 in Tregs from the untreated group and CR group were all significantly lower than that of the control group (P<0.05). The percentage of Tregs in CD4+T cells in the untreated group was positively correlated with the proportion of bone marrow plasma cells (P<0.05). The percentage of Tregs in CD4+T cells from 15 MM patients who received bortezamib and dexamethasone (VD) chemotherapy was negatively correlated to the ratio of plasma cell reduction after the first VD chemotherapy (r=0.735, P<0.01). Conclusion:The level of Tregs in the peripheral blood of MM patients was positively correlated with tumor burden and progression of disease, but was negatively correlated with curative effect. The increased level of Tregs was associated with their strengthened anti-apoptosis function.

Tricho-rhino-phalangeal syndrome (TRPS) was first reported in 1966. Although mutation of TRPS1 gene is considered to be responsible for the syndromes in 2000, investigation of bone metabolism and changes of serum insulin-like growth factor (IGF)-1 level in this kind of patients is rare. Here, we report a patient with TRPS I (MIM 190350) presenting a novel mutation (1096insA) and abnormal changes of severe osteoporosis as well as low serum IGF-I level.

OBJECTIVESTo explore the category, quantity and clinical significance of autoantibodies on bone marrow hematopoietic cells in patients with immunorelated cytopenia and evaluate the sensitivity of direct antiglobulin reaction (Coombs test ) of bone marrow mononuclear cells (BMMNC).
METHODSThe category and the positive rate of autoantibodies on bone marrow hematopoietic stem cells, nucleated erythrocytes, granulocytes in 32 patients with uncertain immunorelated cytopenia were investigated by using BMMNC-Coombs test and double immunofluorescence flow cytometry.
RESULTSThe positive rate of autoantibodies on bone marrow hematopoietic cells tested by flow cytometry was 90.63% which was higher than that by BMMNC-Coombs test (50.0%) (p < 0.05). In 29 positive cases, IgG autoantibody accounted for 6.90%, IgM13.8%, IgG+IgA 3.4%, IgG+IgM 31.0%, and IgG+IgM+IgA 44.8%. Of the 29 Patients, 25 (86.2%) with IgG autoantibody, 26 (89.7%) with IgM and 14 (48.3%) with IgA. The patients with IgG autoantibody alone had the lowest hemoglobin levels, and those with IgM autoantibody might have intravascular hemolytic findings. The response time of patients with IgG and IgG+IgM was shorter than that of the other patients. 91.3% of the patients had autoantibodies on bone marrow hematopoietic stem cells and showed pancytopenia, and 50% of the patients had autoantibodies on nucleated erythrocytes and granulocytes. Eleven of 13 patients with negative BMMNC-Coombs tests had autoantibodies on bone marrow hematopoietic stem cells detected by FACS. There was no significant difference of the quantities of the three categories of autoantibodies of nucleated erythrocytes and stem cells. The quantities of IgA on granulocytes were lower than that of IgG and IgM. There was no significant difference between IgG and IgM on granulocytes. The quantity of IgA on hematopoietic stem cells was significantly higher than that on nucleated erythrocytes or granulocytes.
CONCLUSIONSThe sensitivity of double immunofluorescence flow cytometry assay was higher than that of BMMNC-Coombs test for detecting autoantibodies. In immunorelated cytopenia patients, the predominant autoantibody was IgM which could cause intravascular hemolysis, and the second one was IgG which could cause severe anemia. Most immunorelated cytopenia patients had autoantibodies on hematopoietic stem cells and showed pancytopenia. IgA was more easily seen on the hematopoietic stem cells.

In order to fabricate the HLA-DQA1 genotyping chip and develop an integrated, parallel technical platform to type HLA system, a pair of primers and a set of probes were designed according to the sequences of HLA-DQA1 exon 2, where the polymorphism is concentrated. The oligonucleotide chip was made with the methods developed in our laboratory. The target DNA was asymmetrically amplified with the labeled sense primer. The signals were scanned and analyzed after the hybridization between microarray and PCR product. The allele types of the samples were identified. The result was verified by the standard DNA and DNA sequencing. The results showed that the genotyping was successfully carried out in 50 standard DNA samples and 50 clinical samples. Among them, results of the 50 standard DNA samples matched their templates. In the other 50 samples, results of the randomly selected 10 matched their sequencing results except that two of them got the incompletely result. In reproducible tests, the signal reappear rate was 95%. It is concluded that HLA-DQA1 genotyping by using our array system is simple and convenient with satisfied accuracy and reproducibility.
