Objective To study the safety of tilt table test (TTT) in elderly patients. Methods Among the 785 subjects examined for TTT, 110 were elders with an average age of( 65?4) years, ranging from 60 to 82. Out of the 110 elder subjects, 39 syncope patients were due to unknown reasons, 13 due to heart or brain diseases and 58 were non syncope subjects. We conducted base tilt table test (BTTT) in all patients and additional isoproterenol tilt table test (ITTT) in 18 patients. The BTTT protocol included 60～80 degrees upright tilt for 25 minutes and the ITTT protocol included isoproterenol infusion at 2-4 ?g/min for 10 minutes. Results 13 out of 39 patients with unknown reasons had a positive BTTT and 6 out of 10 patients had a positive ITTT, respectively; Among the 31 out of 110 positive TTT patients, 17 (54.8%) showed a vasodepressor response, 4 (12.9%) a cardioinhibitory response and 10 (32.3%) mixed response. Serious abnormal responses were not observed. Conclusions (1) TTT is a safe and effective method for diagnosing the vasovagal syncope (VVS) in elderly patients; (2) Because of its safety, BTTT could be chosen for identifying the VVS in the elderly heart or brain disease patients complicated with syncope.

In the cultural construction of independent institute,there exist the contradiction between tradition and innovation,cultural conflicts between private enterprises and the university.Therefore,adhering to the people-centered concept,coordinating tradition and innovation,merging the advantages of university culture and private enterprises culture into a whole,cultivating the unique spiritual culture,harmonious system culture and unified material culture of independent institute,forming the distinctive “Institute Culture” with its own cultural tradition will provide reference for the theory and practice to enrich and improve the connotative development of independent institute.

Objective To observe the influence of taurine supplementation during early postnatal life on body weight and ultrastructure of islet ? cells in neonatal rats with low birth weight(LBW).Methods LBW neonatal rats were made by feeding 20%(C group) or 10%(R group) protein diet to fetal rats during gestation and lactation.Half of femal rats in group R were given a supplementation with 2.5% taurine drinking water(RT group) only during lactation,while other femal rats freely drunk.At postnatal day 1 and 21,the neonatal rats were weighted and their pancreas were removed.The ultrastructural changes of ? cells were observed by electron microscopy.Results At postnatal 21 days,the body weight of offsprings in group RT was significantly highter than that in group R(P=0.003);and the ultrastructure of ? cells in group RT got more improvement than that in group R.Conclusion Taurine supplementation can improve the growth-catch-up and the ultrastructure of islet ? cells of neonateal rats with LBW.

Objective: To systematically assess the effectiveness and safety of using acupuncture-moxibustion therapy alone to treat adult overactive bladder (OAB) by taking oral Western medication solely as the control, and to provide evidence-based reference for acupuncture-moxibustion treatment of OAB. Methods: A systemic search was conducted through China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), PubMed, Cochrane Library, and Excerpta Medica Database (EMBASE). RevMan 5.3 was used for meta-analysis. Statistical descriptions were made using standardized mean difference (SMD), confidence interval (CI), and risk ratio (RR). Results: Eight randomized controlled studies were finally recruited and were analyzed after being grouped according to intervention methods. Regarding urinary symptoms, compared with sole use of oral Western medication, acupuncture plus moxibustion can more effectively reduce 24 h urinary frequency [P=0.01, SMD=-0.57, 95％CI (-1.02, -0.12)], 24 h nocturia frequency [P=0.03, SMD=0.49, 95％CI (0.05, 0.94)], and OAB syndrome score (OABSS) [P<0.001, SMD=-3.67, 95％CI (-4.48, -2.86)]. Acupuncture combined with moxibustion and oral Western medication work equivalently in comparing 24 h urinary urgency frequency [P=0.38, SMD=-0.17, 95％CI (-0.57, 0.22)], 24 h urgent incontinence frequency [P=0.25, SMD=0.26, 95％CI (-0.18, 0.70)], and single voiding volume [P=0.22, SMD=1.15, 95％CI (-0.70, 3.00)]. There were no significant differences between acupuncture/electroacupuncture and oral medication in comparing 24 h urinary frequency [P=0.46, SMD=0.07, 95％CI (-0.12, 0.26)], 24 h urinary urgency frequency [P=0.18, SMD=0.70, 95％CI (-1.71, 0.32)], 24 h nocturia frequency [P=0.46, SMD=-0.71, 95％CI (-2.60, 1.17)], 24 h urgent incontinence frequency [P=0.08, SMD=-0.22, 95％CI (-0.48, 0.03)], single voiding volume [P=0.09, SMD=0.17, 95％CI (-0.02, 0.36)], or OABSS [P=0.96, SMD=-0.07, 95％CI (-2.65, 2.52)]. Compared with oral Western medication, moxibustion can more effectively reduce 24 h urinary frequency [P<0.001, SMD=-6.53, 95％CI (-7.65, -5.44)] and 24 h urinary urgency frequency [P<0.001, SMD=-1.6, 95％CI (-2.85, -0.36)]. In comparing the adverse reaction rate, acupuncture-moxibustion was associated with a lower rate compared with oral medication [P=0.002, RR=0.07, 95％CI (0.01, 0.37)], but the difference was statistically insignificant between acupuncture/electroacupuncture and oral medication [P=0.40, RR=0.57, 95％CI (0.16, 2.12)]. Conclusion: Acupuncture-moxibustion is equivalent to the sole use of oral Western medication in improving urinary symptoms in OAB patients and has a higher safety rating.

Objective Based on the diagnostic technique of electric meridian detection, to observe the clinical efficacy of acupuncture in treating angioneurotic headache.Method Totally 106 patients with angioneurotic headache were randomized into a treatment group and a control group, 53 cases in each group. The treatment group received acupuncture based on the electric meridian detection, while the control group received medication treatment. The hemorheology indexes [plasma viscosity (PV), erythrocyte sedimentation rate (ESR)] and McGill Pain Questionnaire (MPQ) [Pain Rating Index (PRI), Visual Analogue Scale (VAS), and Present Pain Intensity (PPI)] were observed before and after intervention, and the clinical efficacies were compared. Result The total effective rate was 88.7% in the treatment group versus 71.7% in the control group, and the between-group difference was statistically significant (P<0.05). After intervention, the hemorheology indexes and MPQ scores were significantly changed in both groups (P<0.01,P<0.05).Conclusion Acupuncture based on electric meridian detection is an effective method in treating angioneurotic headache.

OBJECTIVETo investigate the migration of fluorescent dye PKH26-labeled BM-MSC in the Alzheimer's model rats.

METHODSNormal human bone marrow extracted for isolation of BM-MSC was cultured in vitro. The 5th passaged BM-MSC was labeled with PKH26, and observed under a fluorescence microscope for PKH26 labeling efficiency, and using flow cytometry BM-MSC surface markers was checked. The PKH26 labeled BM-MSC injected into the tail vein of the normal control group and AD animal model group, 14 days after finding the PKH26-labeled BM-MSC cells in the rat hippocampus using fluorescence microscopy. Using the Morris water maze experiment comparison of AD model and BM-MSC transplantation group of spatial learning and memory ability.

RESULTSTFlow cytometry showed BM-MSC surface markers CD73 and CD105 were positive. In vitro, PKH26-labeled rate of BM-MSC was 100 %. The Morris water maze experiment comparison of BM-MSC transplantation group and AD group of animals, BM-MSC transplantation group at 13, 14 days of spatial learning and memory ability than AD animal group had significantly improved. 14 days after BM-MSCs in rat hippocampus could be found which were PKH26-positive, consistent with DAPI staining. PKH26-positive cells in animal models of AD were significantly more than those in the normal control group.

CONCLUSIONBM-MSC in AD rats not only migrates through the blood-brain barrier, but also mainly survives in the hippocampus of AD rats, and it can improve AD rat model of learning disabilities.
