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.

Objective To explore the repair effect of methylcobalamin treatment of nerve after spinal cord injury.Methods 108 cases of patients with acute spinal cord injury were selected treated in our hospital from 2010 April to 2014 April , including 60 cases of male, female 48 cases, were randomly divided into Mecobalamin group(n=56) and control group(n=52), mecobalamin group was treat with a cobalt amine, control group was given conventional treatment (dexamethasone intravenous drip note).According to American spinal cord injury score (ASIA) to set sensory function, motor function and spinal cord function score criteria, observed and record ed the sensory function, motor function, recovery of neurological function and complications the two groups of patients were treated for 6 weeks and followed up for 6 months.Results Spinal cord injury patients after 6 weeks and 6 months follow-up, the improvement of sensory and motor function of mecobalamin group were significantly better than the control group ( P <0.01 );Mecobalamin group patients after first to 3 weeks of recovery of neurological function was higher than those of the control group (P<0.05);the 2 groups were found urinary tract infections, lung infections, vomiting, reaction of ulcer complications, but the difference was not statistically significant ( P>0.05).Conclusion In patients with acute spinal cord injury treated by mecobalamin treatment can improve the nerve function damage condition, improve the prognosis and quality of life.

Objective To study the role of IL-2 in regulating allograft rejection mediated by alloantigen-specific CD8~+ T cell.Methods T cell proliferation in vivo at a single cell level was examined using the CFSE dilution assay. IL-2 expression by activated CD4~+ versus CD8~+ T cells was determined by intracellular cytokine staining. The ability of alloantigen-specific CD8~+T cells in mediating allograft rejection was studied using the islet transplantation model.Results CD8~+ T cells divided vigorously in vivo in the allogeneic hosts regardless the presence or absence of CD4~+ T cells. CD4~+ T cells, but not CD8~+ T cells, were the primary source of IL-2 when both subsets were present. However, CD8~+ T cells could express high levels of IL-2 in the complete absence of CD4~+ T cells. In 2C TCR transgenic (Tg) mice in which the 2C TCR transgene was selectively expressed on the CD8~+ T cells that specifically recognized alloantigen (Ld) of Balb/c origin, islet allografts from Balb/c mice was promptly rejected by the 2CTg recipients with mean survival time of only 8 days. In contrast, in 2CTg mice with a genetic deletion of the IL-2 gene (2CTg-IL-2KO mice), the alloantigen specific CD8~+ T cells failed to mediate the islet allograft rejection and all the Balb/c islets survived for more than 50 days.Conclusions CD8~+ T cells appear to be very plastic in producing and utilizing IL-2. In the presence or absence of CD4~+ T cells, CD8~+ T cells can use CD4~+ derived or self derived IL-2 for proliferation and effector function respectively. In an alloantigen specific TCR transgenic model, the effector function of CD8~+ T cells is strictly IL-2 dependent. Thus, in situations where graft rejection is mediated solely by the CD8~+T cells, blocking IL-2/IL-2R pathway may be critically important in preventing transplant rejection.

Objective To understand awareness of basic knowledge on control and prevention for chronic obstructive pulmonary disease (COPD) among general practitioner in community health service centers. Methods Questionnaire survey was conducted among 593 general practitioners at 15 community health service centers in a district of Shanghai in the morning of February 26, 2008. Results Five hundred and forty-two of 593 ( 91.4% ) general practitioners surveyed knew that chronic obstructive pulmonary disease can be abbreviated as COPD, and 315 of them (53.1%) thought they knew the main contents of the "Guidelines for Prevention and Control of Chronic Obstructive Pulmonary Disease". No pulmonary function instrument was equipped at all 15 community health service centers surveyed, and 501 of 593 ( 84.5% ) general practitioners knew spirometry is gold standard for diagnosis of COPD. Only 115 ( 19.4% ) general practitioners knew that COPD can be categorized as acute exacerbation and stable stage. One hundred and sixty-three of them (27.5%) knew that drug therapy should be maintained in COPD patients for long term following effective treatment, 328 (55.3%) recognized that treatment for COPD patients was still needed in their stable stage, and 312 (52.6%) believed that antibiotics may not be necessary and 465 (78.4%) thought that inhalation therapy was the choice of treatment for acute exacerbation of COPD. Two hundred and thirty-five of them (39.6%) knew that oxygen inhalation should be more than 15 hours per day in regular family therapy. The investigation showed that 365 (61.6%) general practitioners had participated in training for COPD-related knowledge, only one or two times a year. Awareness of COPD knowledge was significantly poorer in rural practitioners than that in urban community ones. Conclusions Basic knowledge of prevention and treatment for COPD was seriously lack in general practitioners, so it is a necessity to strengthen training for them.
