Objective To observe the effect of acupuncture and herbs on risk factors and prognosis of transient ischemic attack (TIA).Methods 120 patients received treatment from March to May 2011 in Gaomi People's Hospital and the Hospital of Gaomi were randomly divided into three groups,with 40 cases in each.Acupuncture and Chinese medicine group was treated with needling Neiguan and administered with modified Tianmagouteng decoction,3 times/d; Chinese medicine group was treated with modified Tianmagouteng diction exclusively,3 times/d; Western medicine group was treated with Aspirin,0.1 g,1 times/d.The three groups were treated for 30 d of two therapeutic courses.TCM syndrome score,blood pressure,blood lipids,blood rheology,blood sugar changes in the three groups of patients were observed before and after the treatment.And follow-up of elapse rate and the incidence of stroke in a year were observed.Results After treatment,① in the acupuncture and Chinese medicine group: the total cholesterol was (5.21 ± 0.97)mmol/L,whole blood viscosity was [(4.26±0.66) 200 mPa · s,(5.69±0.15) 30 mPa · s,(9.72±2.33) mPa · s],fibrinogen was (2.12± 0.46)g/L,systolic blood pressure was (124.13±9.96) mm Hg,diastolic blood pressure was (79.23±7.50) mm Hg,blood glucose was (5.59 ±0.78) mmol/L; in the Chinese medicine group,the total cholesterol was (5.43± 1.04) mmol/L,whole blood viscosity was [(4.25±0.25) 200 mPa · s,(5.46±0.55) 30 mPa · s,(9.81± 2.01) 5 mPa · s],fibrinogenwas (2.32±0.33) g/L,systolic blood pressure was (129.78±14.25) mm Hg,diastolic blood pressure was (79.54± 7.65) mm Hg,blood glucose was (5.60± 0.75) mmol/L; in the western medicine group,the total cholesterol was (5.52± 1.16) mmol/ L,full blood viscosity was [(4.12±0.54) 200 mPa · s,(5.45± 0.65) 30 mPa · s,(9.09 ± 1.11) mPa · s],fibrinogen was (2.41 ± 0.44) g/L,systolic blood pressure was (129.83 ± 14.91) mm Hg,diastolic blood pressure was (80.72±7.47) mm Hg,blood glucose was (5.75 ± 0.61) mmol/L.all these results were improved significantly than those before the treatment in the same group (P＜0.05),and the acupuncture and Chinese medicine group improved better than the other two groups (P＜0.05).② In 1-year follow-up,TIA recurrence rate of stroke in the acupuncture group were lower than the other two groups.Conclusion Acupuncture and Chinese medicine treatment were not only be able to improve the clinical symptoms of patients with TIA and blood pressure,blood lipids,blood theology,blood sugar and other risk factors for TIA patients significantly,but also can effectively reduced the relapse rate and the incidence of stroke.

Objective To explore the role of p170, MRP, bcl-2 in clinical drug- resistance and their correlation. Methods There are 44 acute leukemia(AL) patients, among them ANLL is 29, ALL is 15.The expression of p170, MRP, bcl-2 were detected. At last, the patients were divided into two groups: CR and NR according to efficacy after two periods standard chemotherapy. Results Overexpression of p170, MRP,bcl-2 were found in AL (P ＜0.05). The expression of p170 and MRP were lower in CR group than that in NR groups in AML and ALL; there were 22 of 24 patients expressed one or two proteins in NR groups and the expression of p170 in patients was concordant with that of MRP to certain extent (P ＜0.01). The overexpression of bcl-2 was related with the worse prognosis. The expression of bcl-2 was lower significantly in CR group than in CR and NR (P＜0.05). Conclusion p170, bcl-2, MRP are all associated with clinical MDR. High expression of these proteins is an unfavorable factor to prognosis. The expression of MRP and p170 showed coincidence, but showed no significance with expression of bcl-2 in untreated patients, it indicated that the drug-resistance mediated by p170 was different from bcl-2.

Objective To explore the diagnosis and differential diagnosis of spinal muscular atrophy with respiratory distress type Ⅰ (SMARD1). Method The clinical data, results of gene detection, and follow-up information of a girl diagnosed with SMARD1 were retrospectively analyzed, and related literatures were reviewed. Results The girl was born by cesarean section due to oligohydramnios. After birth, she was transferred to neonatology department for poor feeding and response, and diagnosed with neonatal sepsis, infectious shock, disseminated inravascular coagulation and atypical purulent meningitis. She was discharged after one month of treatment. However, at 2 months old, she presented contracture of ankle joint, abnormal liver function, and myocardial damage. At 6 months old, she had obvious reduced muscular tension and development retardation. At 8 months old, the SMA gene was detected and it was normal. At 9 months old, The panel gene of peripheral neuropathy was detected and found 2 heterozygosis mutations in IGHMBP2 gene, exon8 c.1061-2A>G and exon12 c.1708C>T, which came from her father and mother respectively. Locus of exon12 c.1708C>T has been reported to be associated with the disease, and the other is a shear mutation. The diagnosis of SMARD1 was confirmed by the clinical and gene detection. The girl, 2-year-old now, suffered with recurrent respiratory tract infections, but had no respiratory distress or no respiratory failure yet. Conclusion The clinical phenotype of SMARD1 is complex and diverse. This case is the first domestic case comfirmed by gene detection.
