BACKGROUND: Xingnao kaiqiao acupuncture is a series of systematic acupuncture methods with yin channels in domination, assisted by specified standards of quantity manipulation, which was founded according to the pathogenesis of stroke, and it is effective in treating stroke.OBJECTIVE: To observe the effects of xingnao kaiqiao acupuncture on blood lipids and blood viscosity in stroke patients of different syndrome types.DESIGN: A comparative observation.SETTINGS: Institute of Acupuncture and Moxibustion, and Special Care Ward of Acupuncture, the First Affiliated Hospital of Tianjin College of Traditional Chinese Medicine.PARTICIPANTS: Totally 750 stroke inpatients (466 males and 284 females) were selected from the Special Care Ward of Acupuncture, the First Affiliated Hospital of Tianjin College of Traditional Chinese Medicine between January and December in 2001, the average age was (64±12) years,the disease course ranged from 2 hours to 3 years. All the patients were informed and agree with the therapeutic program.METHODS: ① The traditional Chinese medicine (TCM) syndrome differentiations of stroke were in reference to the fifth edition of Traditional Chinese Medicine and Internal Medicine. There were 688 cases of stroke of meridian and collateral type and 47 cases of stroke attacking zang-fu organs type. ② Huatuo filiform needles produced by Suzhou [1.0-1.5 cun in length, 0.32-0.38 mm in diameter (No. 30-28)] were used in the xingnao kaiqiao acupuncture. Firstly, the acupoints of bilateral Neiguan were acupunctured perpendicularly for about 0.5-1.0 cun, the reducing manipulation by twirling as well as lifting and thrusting the needle was performed for 1 minute; Secondly, the needle was inserted at Renzhong towards nasal septum for about 0.3-0.5 cun, the manipulation of heavy bird-peck needling was used till the eyeballs were wet or tears fell down; Then Sanyinjiao was acupunctured, the needle was inserted along the medial border of tibia at an angle of 45° with skin for about 1.0-1.5 cun, the reinforcing manipulation by lifting and thrusting the needle was performed till the ipsilateral lower limb had three tics; The acupoint of Weizhong was selected by lying and lifting the leg, the needle was inserted perpendicularly for 0.5-1.0 cun, and the reducing manipulation by lifting and thrusting was applied till the ipsilateral lower limb had three tics; The acupoint of Jiquan was acupunctured at 1 cun below the source point along the channel in avoidance of axillary hairs, the needle was inserted perpendicularly for 1.0-1.5 cun, and the reducing manipulation by lifting and thrusting was applied till the ipsilateral upper limb had three tics; The elbow was flexed to 120° for acupuncture at Chize, the needle was inserted perpendicularly for 1.0 cun, the reducing manipulation by lifting and thrusting was applied till the ipsilateral upper limb had three tics. Twice a day for 7 days as a course. ③ After four courses averagely, the whole blood viscosities were detected with the hemorrheologic detector, and the normal ranges for lowshear, middle-shear and high-shear of whole blood viscosities were 6.50-9.25, 4.35-5.45 and 3.65-4.40 mpa ·s respectively. The levels of total cholesterol and triglyceride were detected with blood lipid detector, and the normal ranges were 3.38-6.5 mmol/L and 0.56-0.147 mmol/L.MAIN OUTCOME MEASURES: The effects of xingnao kaiqiao acupuncture on the blood lipids and blood viscosity in stroke patients of different syndrome types were observed.RESULTS: Totally 690 and 721 cases finished the detections of whole blood viscosities and blood lipids respectively. There were obviously fewer cases with normal whole blood viscosities in the patients with stroke of meridian and collateral than in those with stroke attacking zang-fu organs (10.3%, 15.4%, P ＜ 0.01), but markedly more cases with higher total cholesterol and triglyceride than in those with stroke attacking zang-fu organs (80.5%, 91.5%; 64.1%, 71.3%; P ＜ 0.01).CONCLUSION: The levels of blood lipids in the patients with stroke of meridian and collateral are more abnormal than in those with stroke attacking zang-fu organs, but their blood viscosities are better than in those with stroke attacking zang-fu organs.

Objectives To study the effect of highway transportation on the quality of red blood cells. Methods Highway transportation environment was simulated by random vibration test. Red blood cell suspensions and whole blood were vibrated for 120 minutes based upon GB/T 4857.23-2003 with the RMSVA of 0.38 and 0.52grms, as well as GJB 2711-1996 with the RMSVA of 1.04grms and weight loading of 60kg. Five ml of specimen were taken before the testing (as Control Group), and after the testing at 30mins' intervals (as Testing Group). K+, FHb and red blood cell osmotic fragility were tested. Results The red blood cell osmotic fragility of whole blood increased in 0.38grms, 90min and 0.52grms, 60min specimens (P

Objective To validate and compare the two spinal microdialysis techniques: a linear tissue probe (LM-3) in the spinal dorsal horn and a loop probe in the cerebral spinal fluid (CSF) in determining peripheral nociceptive stimulation-evoked glutamate (Glu) release in the spinal cord of freely moving rats. Methods Twenty-eight adult male Wistar rats weighing 300-350 g were randomly divided into two groups: in group A a LM-3 probe was implanted into the spinal dorsal horn and in group B a loop probe was placed in the CSF. Twenty-four hours after the implantation of the probe, microdialysis was initiated with perfusion of modified Ringer' s solution at a low flow rate of 5 ?l?min-1 . Following an 1 h equilibration phase the baseline Glu concentrations were measured every 10 min for 1 h. Thereafter 50 ?lof 5% formalin was injected into one hindpaw of the rats and samples were collected every 10 min for 90 min. Furthermore 8 rats in group A were further divided into 2 subgroups to investigate the effects of the flow rate of microdialysis and composition of perfusate on the baseline Glu release.Results The baseline levels of Glu were (0.82?0.09) ?mol?L-1 with LM-3 probe and (5.96?0.22) ?mol?L-1 with the loop probe. In group A (LM-3 probe) when the flow rate of the modified Ringer's solution was decreased from 5 to 2 ?l?min-1 the extracellular Glu concentrations were increased to 223%?7% of the baseline (n = 4) , whereas perfusion with artificial CSF reduced Glu concentrations to 62% ?10% of the baseline (n = 4) . Injection of formalin into the hindpaw induced a short-lasting but significant increase in Glu concentration with a similar profile and time course using either of the two microdialysis approaches. Conclusion Microdialysis in the dorsal horn or in the CSF are both effective techniques to assess Glu release in the spinal cord of rats. Peripheral nociceptive input induces a short-lasting increase in Glu release with a similar profile and time course using either of the two microdialysis approaches. The microdialysis of the dorsal horn provides a useful tool to precisely locatewhere the release of the neurotransmitter occurs, whereas the loop probe in CSF is more reproducible for simultaneous investigation of drug effects.

Objective To study the hydrogen sulfide productivity by mononuclear cells in patients with atrial fibrillation (AF). Methods Mononuclear cells were extracted from peripherial blood of 60 AF patients and 30 healthy controls. Modified methylene blue method was used to evaluate the hydrogen sulfide productivity of mononuclear cells. Results Hydrogen sulfide productivity of mononuclear cells from AF patients was 92.5%higher than that from control [10.63 (8.21~14.37) μmol/(min.g protein) vs 5.52 (4.42~8.50) μmol/(min.g protein)]. Hydrogen sulfide productivity of mononuclear cells was correlated with the left atrial transverse diameter (r = 0.276,P < 0.01), while no significant correlation was found between hydrogen sulfide and left ventricular end-diastolic diameter , left atrial anterior posterior diameter , C-reaction protein etc. Conclusion Hydrogen sulfide productivity of mononuclear cells from AF patients is promoted.

OBJECTIVE:To investigate the correlation of gene polymorphism in peripheral artery disease(PAD)patients with antiplatelet efficacy of clopidogrel. METHODS:Reviewing related domestic and foreign literatures in recent years,the correlation of gene polymorphism in PAD patients with antiplatelet efficacy of clopidogrel was summarized and analyzed. RESULTS&CON-CLUSIONS:At present,a variety of genes associated with clopidogrel antiplatelet efficacy and major adverse cardiovascular events (MACE)have been identified,including cytochrome P450(CYP)2C19,adenosine three phosphate binding cassette B subfamily 1 (ABCB1),paraoxonase 1 (PON1) and adenosine diphosphate P2Y12 receptor (P2Y12),etc. CYP2C19*2,*3 allele may reduce the antiplatelet effect of clopidogrel. Their correlation has been confirmed by a number of studies,and study results are broadly con-sistent. Mutations in the ABCB1 C3435T and PON1 Q192R sites may lead to a lower response to clopidogrel and increase the risk of MACE;but there is a lack of large-scale prospective clinical studies,and the present results are inconsistent. P2Y12 gene poly-morphism in PAD patients has not been found to be significantly associated with clopidogrel efficacy.

Objective To investigate the relationship between the expression of DNA methyltransferases(DNMT)and clinical prognosis in children with acute leukemia(AL).Methods The mRNA expressions of DNMT1,DNMT3A,DNMT3B,p15,mdrl were measured in 56 AL children and 20 normal controls by semi-quantitative reverse transcriptionpolymerse chain reaction.Results In 56 cases of children with AL,the positive rate of DNMT1 was 73.2%(41/56);the positive rate of DNMT3A was 67.9%(38 /56);the positive rate of DNMT3B was 64.3%(36/56).Thirty-one cases showed positive expressions of the 3 DNMT simultaneously,4 cases with negative expressionss imultaneously,21 cases with at least 1 positive expression of the DNMT,positive rate of p15 was 19.6%(11/56);positive rate of mdrl was 28.6%(16/56),all 3 simultaneous expressions of the 3 DNMT in AL children were significantly higher than those in normal controls(P

Objective To compare the clinical outcomes of segmental pulmonary veins isolation (SPVI) and circumferential pulmonary veins ablation (CPVA) for patients with paroxysmal atrial fibrillation. Methods Sixty-eight patients with paroxysmal atrial fibrillation from January 2004 to April 2008 were divided into SPVI group (30 cases) and CPVA group (38 cases).The mean procedure time,the mean fluoroscopy time and relapse rate were compared. Results The mean procedure time in CPVA and SPVI group had no significant difference [(171.0 ± 25.8) min vs (168.2 ± 21.7) min, P = 0.579], but the mean fluoroscopy time in CPVA group [(38.5 ± 8.4) min]was less than that in SPVI group [(45.8 ± 16.1) min (P= 0.019). Mean term of the follow up was (17.1 ± 7.8) months. Relapse rate in CPVA group was less than that in SPVI group (5.3% vs 23.3%, P= 0.029). Both groups had no severe complications. Conclusion In patients with paroxysmal atrial fibrillation, CPVA strategy provides a more favourable clinical outcomes and less fluoroscopy time.

Objective To assess the efficacy of early detection of breast cancer and the prognostic value of breast self-examination(BSE).Methods Randomized controlled trials(RCTs)involving BSE were included the present meta-analysis based on their qualities.The pooled analysis was performed with RevMany 4.2.8.Results Three RCTs were identified and then they were included the present metaanalysis.In women who conducted a BSE.the rate of biopsy fora lump in breast was 1.27%in the first 5 years,2.47%in more than 5 years but less than or equal to 10 years,and 2.50%in more than 10 years, respectively,all of which were significantly higher than in those who could not conduct a BSE(P<0.05) There was no significant difierence in the rate of final diagnosis and the mortality for breast cancer between the two populations in any follow-up time(P>0.05).Conclusion The rate of biopsy for a lump in breast in women could be increased by a BSE.which should not have been discarded from the early detection of breast cancer completely despite it is not helpful in increasing the rate of final diagnosis and decreasing the mortality for breast cancer.
