Objective To explore the effects of three kinds of respiratory training methods on pulmonary function and quality of life in patients with thoracic cancer radiotherapy. Methods A total of 76 patients with thoracic cancer were divided into the control group (20 cases), the retracting-lip breathing group (19 cases), the blowing balloons group (18 cases), and the resisting respiratory exercise group (19 cases) by the draw method. Based on conventional health services, the retracting-lip breathing group, the blowing balloons group, and the resisting respiratory exercise group were given respiratory training (one month), whereas the control group only followed routine nursing care. The pulmonary function and quality of life were measured at the first and the thirtieth day of radiotherapy by electronic pulmometer and quality of life instruments for cancer patients-general module respectively. Results The indicators of pulmonary function at thirtieth day of patients in each group were lower than those at the first day, the intragroup differences were significantly (t=2.17-6.32, P<0.01), whereas no significantly different among intergroups (P>0.05). Scores of quality of life of the retracting-lip breathing group were (78.74±5.51) points, the blowing balloons group were (78.43 ± 7.41) points, the resisting respiratory exercise group were (79.11 ± 8.84) points, which were significantly increased than that of control group (73.01 ± 7.46) points(F=3.00, P < 0.05). Conclusions The pulmonary function of patients with thoracic cancer radiotherapy significantly reduces after radiotherapy. Three kinds of respiratory training show no effects on pulmonary function, but the quality of life of patients with thoracic cancer radiotherapy could be improved.

Objective To investigate the expression of cyclooxygenase-2 (COX-2) and epidermal growth factor receptor (EGFR) in astrecytomas, as well as the correlation between them. Methods The expression of COX-2, EGFR and PCNA were respectively detected by immunohistochmical (S-P) method in 68 astrocytomas and 5 cases normal brain tissue. Proliferation index (PI) was calculated and the correlation of COX-2, EGFR and PI was analyzed. Results COX-2 and EGFR were negative expression in normal brain tissue. The positive expression rate of COX-2 and EGFR in high grade astrocytomas was significantly higher than that in low grade astrocytomas(73.53% vs 44. 18% ,67.65% vs 38.24%, P <0. 01 ), and the PI was significantly higher than that in low grade astrocytumas as well as normal brain tissue(46.11 ± 10. 68vs 23. 04±6. 25,4. 52±0. 95, P <0. 01 ). The PI in COX-2 positive group was higher than that in negative group( P <0. 01 ). The positive expression rate of COX-2 in the group with EGFR positive expression was higher than that in the negative group. Conclusions The expression of COX-2 and EGFR was related to pathological feature of astrocytomas. COX-2 may promote the proliferation of tumor cells. There was a static correlation between the expression of EGFR and COX-2 in astrocytomas. EGFR signal transduction probably modulated the expression of COX-2 in astrocytomas cells.

Vascular dementia (VaD) is the second common subtype of dementia after Alzheimer's disease. However, there is still a lack of medication that demonstrates clinically relevant symptomatic improvement. Static blood obstructing the brain is the main Chinese medicine syndrome of VaD.

Objective To explore the relationship between the HLA-G 14 bp insertion/deletion polymorphism and the infection of Epstein-Barr virus(EBV) for children.Methods The study genotyped HLA-G 14 bp insertion/deletion polymorphism of 102 infectious mononucleosis children and 165 normal controls by PCR-PAGE,detected the plasma sHLA-G level of 51 infectious mononucleosis children and 146 normal controls by ELISA.Results A significant difference was observed for the frequencies of the HLA-G 14 bp genotype between the two groups( x2 =6.742,P=0.034 ),and a significant difference was also observed for the 14 bp allele frequencies between the two groups( x2 =6.672,P=0.01 ).The plasma sHLA-G levels in the infectious mononucleosis children were dramatically higher than that in normal controls,and a significant difference was observed between the two groups( Z=-9.472,P＜0.01 ).Among the infectious mononucleosis children,levels of sHLA-G was find a significant difference between the three genotypes of HLA-G 14 bp insertion/deletion polymorphism( H=6.09,P =0.048 ),and the level of s HLA-G with 14 bp+/+ genotype was markedly lower than that of the two other genotypes (Z=-2.376,P=0.01 8).Conclusion There was a relationship between the HLA-G 14 bp insertion/deletion polymorphism and the susceptibility to the infectious mononucleosis for children.Children who carried the 14 bp-/- genotype or deleted the 14 bp allele may have a significantly increased risk of the infection of EBV.The plasma sHLA-G might be considered as an index for auxiliary diagnosis infectious mononucleosis.

AIM: To investigate the changes of the L-type calcium channel subunit expression and calcium currents (I_~Ca -L) in cultured rat ventricular myocytes infected by coxsackie virus B_3 (CVB_3). METHODS: Primary cultured neonatal rat ventricular myocytes were infected with CVB_3. The changes of L-type calcium channel subunits mRNA in normal and infected myocytes were measured by semi-quantitative reverse transcription-polymerase chain reaction. I_~Ca -L was recorded in two groups respectively using whole cell patch-clamp techniques. RESULTS: The expression of ?_1 and ? subunits of L-type calcium channel mRNA increased in the infected group compared with the normal one (4.00?0.07 vs 2.21?0.41, P0.05). The average current density of I_~Ca -L significantly increased by CVB_3 infection [(-8.66?0.99) pA/pF vs (-6.97?1.75) pA/pF, P

Objective To obtain in situ pairing of the variable region genes of the immunoglobulin heavy and light chains of B cells from vitiligo patients. Methods Fifty vitiligo patients were screened by a live melanocyte enzyme-linked immunoabsorbent assay. The sera from seven patients were proved to be strongly positive. Then CD19+ B cells were isolated from the peripheral blood lymphocytes of the 7 patients, then fixed in 10% buffered formaldehyde and permeabilised by Proteinase K. The mRNA was amplified within the cells by reverse transcription-polymerase chain reaction (RT-PCR) with specific primers. The immunoglobulin VH and VL DNA assembled within the same cells using the Cre/loxP system. Nested primers were designed to amplify the known major human VH and VL gene familes. Result A unique 800bp band was obtained corresponding in size to single chain Fv fragments. Conclusion The in situ pairing of the variable region genes of the immunoglobulin heavy and light chains of B cells is obtained from vitiligo patients by in-cell PCR.
