Objective To evaluate the clinical efficacy of intensive needling stimulation at external Laogong (EX-UE 8) in treating post-stroke hand hypermyotonia.Method Sixty patients with post-stroke hand hypermyotonia were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened by ordinary acupuncture plus strong stimulation at external Laogong (EX-UE 8), while the control group was by ordinary acupuncture. After 8-week treatment, the modified Ashworth Scale (MAS) was used to assess the muscular tension of the affected limbs, Fugl-Meyer Assessment (FMA) was for assessing motor function of the affected hand, and Activities of Daily Living (ADL) was used to evaluate the activities of daily living before and after the intervention.Result The MAS, FMA, and ADL scores were significantly changed after the intervention in both groups (P<0.05). The MAS, FMA, and ADL scores of the treatment group were significantly different from that of the control group (P<0.05).Conclusion Acupuncture at external Laogong (EX-UE 8) with intensive stimulation is an effective approach in treating post-stroke hand hypermyotonia.

Objective To delineate the changes in pattern and time course of semantic and phonological processing during Chinese language cognition study in patients with mild Alzheimer’s disease (AD) and mild cognitive impairment (MCI). Methods Patients with mild AD(n=32)and MCI (n=39) as well as normal controls (NC, n=40) matched with age, gender, level of education were enrolled in the study. Subjects completed Chinese compound word decision task applying both short and long stimulus onset asynchrony (SOA). Semantic, homophonic, semihomophonic and unrelated primes preceded the real words as well as nonwords targets. Subjects were asked to judge whether the targets were real words or nonwords. The reaction time and accuracy were recorded for each response. Semantic and phonological priming effects were analyzed by comparing the related primes versus unrelated primes. Analyses of variance (ANOVA) and t-test were conducted for reaction time and accuracy respectively. Results The mean reaction times of mild AD and MCI groups were prolonged (411 ms and 234 ms) for all types of priming in contrast with NC(P

Objective To screen the preparation process of 3,4,3″-trihydroxy p-terphenyl nanosuspension. Methods The nanosuspension was prepared in combination with the nanoprecipitation and microfluidization method. Taken the particle size for indicator, we investigated the stirring speed and precipitation temperature in the nanoprecipitation process, the homogeneous stress and cycles in the microfluidic process through single factor experiment. In addition, by factorial design, the variety and dosage of stabilizers are investigated. Results The excellent preparation condition of the nanosuspension are as follows: 0 ℃ for the precipitation temperature, 900 rpm for the stirring speed, 1600 bar for the microfluidization pressure and 12 times for cycles. The ingredient ratio for drug: poloxamer 188: lecithin is 1: 0.8: 0.8. Conclusion Through optimizing the preparation technology, we have successfully prepared nanosuspension with lower size , which will lay a foundation for further study.

Objective To evaluate the effects of different interventions on and influencing factors of picky eaters aged 1 to 5 years old.Methods Two hundred and forty-seven individuals were randomly assigned to the Identification and Management of Feeding Difficulties (IMFeD) group (n =147) and the control group (n =100).The IMFeD group received comprehensive guidance once a month,3 times in total;while the control group had traditional eating guidance.Scores of the IMFeD group were compared with the control group.Multivariate method was used for data analysis.Results Behavior scores of the IMFeD group were 4.7 ± 1.1 at baseline and 9.5 ± 2.6 after the intervention ; although behavior scores of the control group were 4.9 ± 1.1 at baseline and 6.6 ± 2.3 following the routine guidance (F =32.99,P ＜ 0.001).Univariate analysis showed that those two interventions significantly affected the outcomes of intervention (x2 =52.76,P ＜0.05).Regression analyses revealed an odds ratio (OR) of 6.171 (95％ confidence interval (CI) 3.652-10.428) or 0.448 (95％ CI:0.264-0.761) for intervention strategy and time with parents during their 1 year.Conclusion Family-based periodicity intervention may play an important role in eating behavior change and should be widely conducted in child health care.

Objective To compare the clinical curative effect between mini laparoscopic cholecystectomy (MLC) and conventional laparoscopic cholecystectomy (LC).Methods Using random number table method to divide the patients into conventional laparoscopic cholecystectomy group (30 cases) and mini laparoscopic cholecystectomy group (27 cases).Compared the operation time,bleeding volume,VAS score,postoperative hospital stay,complications.Results No conversion to laparotomy and serious complications,but each group has 6 cases from the three holes increase to four holes,and 4 cases of MLC group were converted to traditional LC.MLC group and LC group,average operation time (57.5 ± 17) min and (50 ± 15) min (P ＞ 0.05);the average postoperative hospital stay was (2.5 ± 1.4) d and (3.1 ± 1.5) d (P ＞ 0.05);postoperative pain degree of MLC group of 6 h and 12 hrespectively (4.8±2.6) and (3.5±1.1),LC group were (5.5 ±2.7) and (5.0±2.1) points (P＜ 0.05).Conclusion Postoperative pain of MLC is lighter than LC,in appropriate cases,is a safe and effective treatment method.

Objective To establish the baseline data about gross α and gross β radioactivity in local foods through a preliminary investigation in Urumqi City.Methods The edible parts of six types of foods, including cereals, vegetables, fruit, nuts, meat and dairy food, were pretreated and sampled.MPC 9604 low background o and gross β measuring instrument was used for determination of gross α and gross β radioactivity.Results The natural gross ot and gross β radioactivity in the cereal, vegetables, fruits, nut, meat, dairy food were 0.88-10.80 and 22.20-148.67 in cereals, 1.17-24.24 and 21.41-318.84 in vegetables, 1.44-4.89 and 43.90-112.67 in fruits, 17.49-43.72 and 287.81-747.40 in nut, 3.04 -19.77 and 41.55-164.51 in meat, and 2.07-2.94 and 44.07-59.02 Bq/kg in milk, respectively.Conclusions There are some differences in the gross natural radioactivity between Urumqi and the other provinces and cities due to possible regional differences.In order to further ascertain baseline of natural radioactivity in food in Urumqi, larger sample sizes and more diverse food types are needed for purposes of dynamic monitoring.

Objective To observe the effects of sodium arsenite (NaAsO2) on apoptosis in primary cultured rat cerebellar granule cell and nerve globin mRNA expression.Methods Twenty 7-8 days postnatal Wistar rats were selected and decapitated cerebellar cortex, granular cell suspension was prepared and 4 × 109/m2 cells were seeded in the culture flask.Cells were exposed to different concentrations NaAsO2 [0 (control), 2, 5 and 10 μmol/L] for 24 h and intracellular reactive oxygen species (ROS) content and apoptosis were determined by laser confocal,while real-time quantitative PCR was used to detect mRNA expression in cultured cells after 24 and 48 h cell culture.Results Fluorescence intensity of ROS of 0, 2, 5, 10 μmol/L fluoride groups were 421.32 ± 53.52,1 082.09 ± 321.58, 2 223.02 ± 1 011.37 and 1 366.87 ± 102.14, the difference was statistically significant (F =5.873,P ＜ 0.05);Apoptosis rates were (8.91 ± 5.63)％, (26.46 ± 1.77)％, (43.65 ± 14.45)％ and (56.04 ± 6.95)％, the difference was statistically significant (F =18.369, P ＜ 0.05);24 h nerve globin mRNA expression were 1.00 ± 0.06,0.77 ± 0.22, 0.43 ± 0.18 and 0.42 ± 0.14, the difference was statistically significant (F =18.235, P ＜ 0.05);48 h nerve globin mRNA expression were 1.00 ± 0.01, 0.89 ± 0.09, 0.60 ± 0.16 and 0.08 ± 0.02, the difference was statistically significant (F =80.843, P ＜ 0.05).Conclusion With increased NaAsO2 concentration, ROS and apoptosis levels are increased, while nerve globin mRNA expression is significantly reduced, suggesting that after the body is stimulated, protective proteins might be consumed, further suggesting nerve globin expression might be involved in nerve damage caused by arsenic.

ObjectiveTo explore the pattern and the time course changes of semantic and phonological processing during Chinese language cognition study in patients with mild Alzheimer's disease(AD) and mild cognitive impairment (MCI).MethodsPatients with mild AD and MCI and normal controls matched with age, gender, level of education were enrolled in the single-character words naming task, which applied short and long stimulus onset asynchrony (SOA). Semantic, homophonic, semihomophonic and unrelated primes preceded the words as well as nonwords targets. Subjects were asked to read the targets aloud. Semantic and phonological priming effects were analyzed by comparing reaction time of semantic, homophonic or semihomophonic related targets to unrelated targets. The reaction time and accuracy for each response were recorded.ResultsThe mean reaction time of mild AD and MCI patients were prolonged for all types of priming in contrast with normal controls. Responses of the normal controls were faster during the long SOA comparing to short SOA, whereas the mild AD group's reaction time was longer for long SOA than for short SOA. Normal controls exhibited homophonic priming, whereas mild AD and MCI groups exhibited tonal inhibition effects.ConclusionThe speed of Chinese language cognitive processing decreased in mild AD and MCI patients. The phonological encoding and accessing ability may be impaired in mild AD and MCI.

Objective To investigate the clinical significance of brain-derived neurotrophic factor (BDNF) from peripheral serum in patients of vascular cognitive impairment (VCI).Methods Forty VCI subjects (including 10 mild cognitive impairment vascular(MCI-V) and 30 vascular dementia(VD)),and the control group for the same period in 40 healthy persons.Enzyme-linked immunosorbant assay (ELISA) was used to measure the serum levels of BDNF,statistical analysis was performed.Results The peripheral serum levels of BDNF in VCI (0.175 ±0.056) ng/L were lower than those of control group (0.211 ±0.061) ng/L,and there were significant differences (t =-2.752,P ＜ 0.05).The levels of BDNF showed no significant difference between MCI and VD ((0.195 ± 0.067) ng/L vs.(0.168 ± 0.052) ng/L,t =1.310,P ＞ 0.05).But they were both significantly lower than the control group (F =4.590,P =0.013).No significant differences were observed in the levels of BDNF between subcortical small vessel dementia (0.178 ± 0.057) ng/L and big vascular dementia (0.154 ± 0.042) ng/L (t =1.278,P =0.212).Conclusion BDNF participate in pathophysiology of VCI,and the serum levels of BDNF may be a candidate marker for clinical diagnosis of VCI.But serum levels of BDNF could not reflect the severity or the type of the VCI.
