Objective To assess the effect of anti- Helicobacter pylori (Hp) treatment on patients with chronic idiopathic thrombocytopenic purpura (cITP). Methods Fifty-nine patients with cITP and positive-Hp were divided into two groups by random digits table:Hp eradication group (30 cases,given a standard anti-Hp treatment) and placebo controlled group (29 cases,received a placebo). The platelet response of two groups was compared after three months' follow-up. Result The platelet response in Hp eradication group (63.3%, 19/30) was significantly higher than that in placebo controlled group (27.6%,8/29 )(χ2 = 7.59, P ＜ 0.05 ), and the increasing level of platelet count in Hp eradication group [ (33.5 ± 21.6)× 109/L] was higher than that in placebo controlled group [(12.6 ± 19.5) × 109/L] (t = 5.52,P ＜0.05).Conclusion Hp eradication treatment can promote the platelet recovery in mild and moderate cITP patients with positive-Hp.

Objective To investigate the evolution of diffusion indices in the pyramidal tract with Wallerian degeneration(WD)due to cerebral infarction using diffusion tensor imaging(DTI),and to study the relationship between early changes of diffusion indices and motor deficit.Methods Fifteen patients (13 males and 2 females)with acute cerebral infarction(within 7 days)were recruited from the Neurology Department from Mar 2006 to Jan 2007.A11 patients were assessed with DTI.National Institutes of Health Stroke Scale(NIHSS),Bathel Index(BI),modified Rankin Scale(mRS)and Motricity Index(MI)within 7 days from onset,and at the second week.DTI was performed with SIEMENS Trio 3.0 T MR scanner.The placement of region of interest(ROI),measurement of diffusion indices were performed by DTI Studio software.The mean diffusivity(MD),the fractional anisotropy(FA),the first eigenvalue (λ1),the second eigenvalue(λ2),and the third eigenvalue(λ3)were computed.Results At the second week.NIHSS was 6.93±3.39.BI 45.33±26.01,mRS 4.33±0.90.and MI 69.47± 60.71.At the second week from onset.MD of the pyramidal tract at the levels of the middle slice of pons and the superior slice of medulla oblongata showed no significant differences between both the two sides at second week from onset. Other ROI showed significant differences between both sides.MD.FA and λ1 of affected side were lower than the unaffected side.λ2 and λ3 of the affected side were higher than the unaffected side.Positive correlations were found between FA and BI(r=0.530,P=0.042),FA and MI(r=0.543,P=0.036)at the second week.Negative correlations were found between FA and NIHSS(r=-0.613,P=0.015)at the second week.Conclusions DTI can detect the changes in the pyramidal tract due to WD within 7-14 days after ischemic stroke.including a decrease of the fractional anisotropy.the first eigenvalue and increased the second and the third eigenvalues.The fractional anisotropy of the second week from onset is related to the outcome of the motor function.

Objective: To observe the clinical efficacy of acupoint pressure plus long-snake moxibustion for upper-limb spastic hemiplegia after cerebral infarction. Methods: A total of 100 patients were randomized into a control group and an observation group, with 50 cases in each group. Both groups were treated with the same conventional internal medicine and rehabilitation training. The control group was treated with additional acupoint pressure therapy, and the observation group was treated with long-snake moxibustion on the basis of the treatment given to the control group. The Ashworth grade, Fugl-Meyer assessment upper limb scale (FMA-UL) and Barthel index (BI) were evaluated, and the root mean square (RMS) values of biceps brachii and flexor carpi radialis on the affected side were measured before and after treatment. The efficacy was evaluated after treatment. Results: After treatment, the total effective rate of the observation group was significantly higher than that of the control group (P<0.05). After treatment, the Ashworth grade of the observation group was superior to that of the control group (P<0.05). The scores of FMA-UL and BI in both groups increased compared with those before treatment (all P<0.05), and the scores of FMA-UL and BI in the observation group were higher than those in the control group (both P<0.05). The RMS values of biceps brachii and flexor carpi radialis in both groups decreased compared with those before treatment (all P<0.05), and the RMS values of biceps brachii and flexor carpi radialis in the observation group were lower than those in the control group (both P<0.05). Conclusion: Based on conventional internal medicine and rehabilitation training, acupoint pressure plus long-snake moxibustion has great therapeutic efficacy for upper-limb spastic hemiplegia after cerebral infarction. It can improve the degree of spasticity of the affected upper limb, reduce the muscle tone of biceps brachii and flexor carpi radialis on the affected side, and enhance the mobility of the affected limb and the activities of daily living.

?AlM: To study the correlation between monocular mild myopic juvenile myopia degree and dominant eye.
? METHODS: Totally 158 patients with juvenile monocularly mild myopia in our hospital from December 2012 to December 2013 were retrospectively analyzed, and cylindrical mirror astigmatism was used for spherical equivalent conversion. On the basis of the myopic degree, they were divided into three groups, 30 cases in group A (-0. 25~-0. 75D), 92 cases in B group (-1. 0~-2. 0D), 36 cases in group C (-2. 25 ~ -3. 0D). The card hole method was selected to measure dominant eye for subjectsat nearly 33cm and 5m. After glasses correction of ametropia, the far and near dominant eyes were received measurement again.
?RESULTS:The monocular mild myopia of dominant eye was compared with the non-dominant eye adjustment function, and there was no significant difference ( P>0. 05 ) . The dominant eye, non - dominant eye mean diopter and other correlations of eyes in the three groups were compared, and there was no significant difference (P>0. 05). The dominant eye of three groups at 5m was compared, and there was significant difference (P<0. 05). The dominant eye of three groups at 33cm was compared, and there was significant difference (P<0. 05). Dominant eye at different visual distance was compared, and there was significant difference (P<0. 05). Monocular uncorrected eye was compared with dominant eye mild afte myopia glassesr, and there was significant difference (P< 0. 05).
?CONCLUSlON: The formation of myopic anisometropia is related to the degree of clearly seeing objects, although glasses correction can improve the clarity and visual, but affect the choice of the dominant eye, because the myopic anisometropia appears most early in the dominant eye, therefore optician correction stage, which should be taken into consideration, and avoid the severity of the adolescent myopia.

Objective To explore the relationship bet-ween air pollution and acute onset of cerebral hemorrhage in Hangzhou.Methods Time-stratified case-crossover study was used to analyze the effect of aerosol optical depth(AOD),PM10,SO2 and NO2 on the acute onset of cerebral hemorrhage.Conditional logistic regression was used to estimate the odds ratios(Ors) and their 95% confidence intervals(Cis) in relation to an increase of one unit of AOD and 10 μg/m3 of air pollutants.Results After adjusted temperature and relative humidity,the Ors of acute onset of cerebral hemorrhage by a unit increase in AOD at a 2 day-lag were 1.727(95%CI:1.103-2.703)in first half year and 2.412 (95%CI:1.230-4.733) at a 2 day-lag in spring.For a 10 μg/m3 increase in SO2,the Ors were 1.119(95% CI:1.019-1.229),1.230(95%CI:1.092-1.386),1.254(95%CI:1.076-1.460) in the whole year(2 day-lag),in first half year(2 day-lag) and in spring(2 day-lag),respectively.NO2 exposure in first half year(2 day-lag) was associated with cerebral hemorrhage,with OR as 0.841(95% CI:0.734-0.964).However,there were no statistical significances for AOD,SO2,NO2 in the rest time-periods(P>0.05).Additionally,no association was found between PM10 and the acute onset of cerebral hemorrhage in any time-periods(P>0.05).Conclusion Our data showed that there was association between air pollution and the acute onset of cerebral hemorrhage,especially in spring and in the first half of the year.

OBJECTIVETo explore the scavenging action of tenuigenin (TEN) on intracerebral amyloid β protein (Aβ) aggregation and the abnormal phosphorylated tau protein and its mechanism in Alzheimer's disease (AD) rats' brain.

METHODSAβ1-40 was injected into the right CA1 region hippocampus to establish the AD model. Successfully modeled rats were divided into the model group, the low, middle, high TEN group. Rats were administered with TEN (18.5, 37.0, 74.0 mg/kg) by gastrogavage. Besides, a sham-operation group was set up. Expression levels of Aβ1-40 and Tau p-Ser262 were detected by immunohistochemistry. Expression levels of ubiquitin (Ub) and Ub-protein ligase E3 were measured by Western blotting.The content of 26S proteasome was detected by ELISA.

RESULTSImmunohistochemical results showed that the number of Aβ and Tau p-Ser262 positively reacted neurons significantly increased in model group, when compared with the sham-operation group (P < 0.01). Results of Western blot showed expression levels of ubiquitinated protein were up-regulated and those of Ub-protein ligase E3 were down-regulated in the model group (P < 0.01). ELISA results showed that the content of 26S proteasome significantly decreased in AD rats' brain (P < 0.01). Compared with the model group, expression levels of Aβ1-40, Tau p-Ser262, and Ub significantly decreased; expression levels of Ub-protein ligase E3 apparently increased; the content of 26S proteasome significantly increased in each TEN treatment group (P < 0.05, P < 0.01). Best effect was shown in 37.0 mg/kg and 74.0 mg/kg TEN groups.

CONCLUSIONSUb proteasome pathway (UPP) participated in the occurrence of AD. TEN could obviously reduce intracere- bral Aβ1-40 accumulation and abnormal tau phosphorylation.
