Objective To observe the effect of connect meridians inducing Yin from Yang on muscle-tension after cerebral infarction. Methods 82 patients with cerebral infarction in Second Hospital of Harbin from 2010 to 2014 were divided into observation group (n=41) and control group (n=41) according to hospitalization order. The observation group accepted acupuncture of connecting meridians inducing Yin from Yang, and the control group accepted the traditional acupuncture method for 2 weeks. The situation of spasticity, the motor limb function of limbs, and activities of daily living were evaluated with modified Ashworth Scale (MAS), Clinic Spasticity Index (CSI), Fugl-Meyer Assessment (FMA) and Barthel index (BI), respectively. Results Compared with the control group, the score of MAS decreased (t=2.212, P=0.030), the score of CSI decreased (t=2.514, P=0.014), the score of FMA increased (t=4.288, P<0.001), and the score of BI in-creased (t=2.970, P=0.004) in the observation group after treatment. Conclusion The acupuncture of connecting meridians inducing Yin from Yang can reduce the muscle-tension of limbs, improve the motor function and increase the activities of daily living.

Objective To study the genotyping of clarithromycin-resistant Helicobacter pylori(Hp) isolates.Methods From March 2007 to October 2007,247 gastric mucosa specimens were collected by the endoscopy from the patients with peptic ulcer or gastritis at the affiliated hospital of Youjiang Medical College for Nationalities.A total of 126 Hp strains were isolated.Resistance to clarithromycin in Hp was determined by E-test.All of the resistant isolates were genotyped with REP-PCR and further clustered with NTsys_2 software.The clinical data was collected for these patients with clarithromycin-resistant Hp.Results The 26 clarithromycin-resistant isolates from the west of Guangxi were divided into six genotypea including Group Ⅰ,Group Ⅱ,Group Ⅲ,Group Ⅲ,Group Ⅳ,Group Ⅴ and Group Ⅵ according to the homology of 78%.Every group have 2,11,1,8,3,1 strains Hp,respectively.Strains of group Ⅱ were isolated from patients with peptic ulcer and most of them from Chuang patients.All strains of group Ⅳ were isolated from patients with gastritis.Conclusions The clarithromycin-resistant isolates were divided into six groups by REP-PCR Disease type.nationality of patients and family history of stomach diseases were associated with the genotypes.

Objective To explore the application value of Fast Dixon technique in MR hip joint scanning.Methods Fifty young volunteers were recruited to perform axial and coronal MR scans of the hip joint.The scanning sequence was Fast Dixon T2WI sequence and conventional Dixon T2WI sequence.A double-blind five-point scale was used to subjectively evaluate the image quality of the two types sequences.The signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)of the axial image were measured at the maximum level of the bladder display.Results In the scores of"good contrast between surrounding tissue and femoral head signal"and"overall image quality",the Fast Dixon T2WI sequence was better than the conventional Dixon T2WI sequence,and the difference was statistically significant(P<0.05).There was no significant difference in the average scores of"whether bladder artifacts affected the diagnosis"and"whether the fat suppression effect was good"between Fast Dixon T2WI sequence and conventional Dixon T2WI sequence(P>0.05).In the objective image quality evaluation,the SNR and CNR of Fast Dixon T2WI sequence were better than those of conventional Dixon T2WI sequence,and the difference was statistically significant(P<0.05).Conclusion The image quality score of the hip joint of young volunteers with Fast Dixon T2WI sequence combined with multiple averaging excitation technique is significantly higher than that of conventional Dixon T2WI sequence.The Fast Dixon T2WI sequence can increase the effect of inhibiting fat and motion artifacts without increasing the scanning time,and the joint face ratio is good.Fast Dixon technique can replace the traditional Dixon technique,thus becoming an optimal choice for hip joint MR scanning.

Objective: To investigate the bacterial species, characteristics and differences of oral bacteria flora of saliva in the longevous elderly between in Bama county and in Debao county in Guangxi, in order to explore the relationship between longevity and oral salivary bacteria flora in the elderly. Methods: The saliva was taken from the longevous elderly in Bama county(BM group)and people aged over 60 years in Debao county(BS group)separately, and the total DNA was extracted.The 16S rDNA-V4 region was amplified by PCR and analyzed by sequencing.The main species and diversity of bacterial colonies were recorded for difference analysis. Results: A total of 14 saliva samples were collected from 7 cases in BM group and 7 cases in BS group.A total of 369 OTUs were generated by cluster analysis of 14 samples.At the genus level, the dominant salivary bacteria flora were Ctinomyces, Capnocytophaga, Chryseobacterium, Fusobacterium, Haemophilus, Lactobacillus, Leptotrichia, Neisseria, Porphyromonas, Prevotella, Rothia, Streptococcus, Veillonella in both BM group and BS group.The OTU PCA analysis showed that some evidence for indeterminate differences was found, but statistically significant differences did not exist in the dominant components of oral flora between the two groups(P>0.05). Also, the same tendency toward the diversity(P>0.05)was presented.Similarly, the species annotation analysis and the heat map showed that there were no significant differences(P>0.05)in oral salivary flora composition between the two groups.Lactobacillu was always the prevailing flora in the Phylume, Class, Order, Family and Genus, but the abundance ratio was different between the two groups as following: Lactobacillus abundance in salivary bacteria flora was higher in BM Group than in the BS group, while Mycoplasma abundance was lower in BM Group than in the BS group(P<0.05). Conclusions The dominant salivary bacteria flora is Lactobacillus in both BM and BS group, while, the abundance of Lactobacillus is higher in the BM group than in the BS group, which indicates that the longevity of population in Bama county may be related to Lactobacillus.

ObjectiveTo investigate the effects of different acupuncture schemes on behaviors, neurotransmitters and inflammation-related factors in post-stroke depressed (PSD) rats. MethodsA total of 72 healthy male Sprague-Dawley rats were randomly divided into normal group, model group, drug control group, scalp acupuncture group, abdominal acupuncture group and combined acupuncture group, 12 rats in each group. The PSD model was prepared using a combination of middle cerebral artery occlusion and chronic unpredictable mild stimulation (CUMS) for the model and each intervention groups. The drug control group was administered fluoxetine, the scalp acupuncture group accepted acupuncture at Baihui (DU 20) and Yintang (EX-HN3), while the abdominal acupuncture group at Zhongwan (RN 12) and Guanyuan (RN 4), the combined acupuncture group at all the four acupoints, for 21 days. They were assessed with Longa neurological function score, body mass, open-field test and sugar-water preference test on the 0 (before modeling), the seventh (before CUMS), the 14th (before treatment) and the 35th day (after treatment). The levels of 5-hydroxytryptamine (5-HT), dopamine (DA), norepinephrine (NE), interferon-γ (INF-γ), tumor necrosis factor⁃α (TNF⁃α) and macrophage migration inhibitory factor (MIF) in the serum were determined with ELISA on the 35th day. Results The neurological function score was lower in the drug control group and the combined acupuncture group thanin the model group (P < 0.01) on the 35th day; while the body mass was higher in the drug control group, the abdominal acupuncture group and the combined acupuncture group than in the model group (P < 0.01); and the number of horizontal span frames, the number of uprightness and the sugar water consumption were higher in the drug control group, the scalp acupuncture group, the abdominal acupuncture group and the combined acupuncture group than in the model group (P < 0.05). There was no significant difference among the four intervention groups (P > 0.05). The levels of 5-HT, DA and NE were higher in the four intervention groups than in the model group (P < 0.01), and the levels of IFN-γ, TNF⁃α and MIF were lower (P < 0.01). 5-HT level was higher in the combined acupuncture group than in the scalp acupuncture group and the abdominal acupuncture group, and the levels of IFN-γ, TNF⁃α and MIF were lower (P < 0.01); the levels of DA and NE was higher in the combined acupuncture group than in the abdominal acupuncture group (P < 0.01). ConclusionThe combination of scalp acupuncture and abdominal acupuncture can improve behavior, neurotransmitters and inflammatory factors of PSD rats, like fluoxetine. Scalp or abdominal acupuncture alone is still effecive, and can be used secondarily.
