Objective:To study the molecular composition of bismuth potassium citrate. Methods:The content of bismuth was de-termined using a volumetric method, the content of potassium was determined by atomic absorption spectrometry, and the content of cit-rate root was determined by ion chromatography. The structure was predicted using 1 HNMR and the crystal structure was studied using X-diffraction test and scanning electron microscopy. The changes in the percentage ratio of the three components were investigated by accelerated stability tests. Results:On the dried basis, the percentage of the three molecular components was bismuth of 35%-38%, potassium of 7%-11% and root citrate of 49%-52%. The NMR spectra and the data indicated that the product had three isomers with the molecular structure of bismuth∶potassium∶root citrate=2∶2∶2. The X-diffraction test and SEM showed that the three forms of amor-phous, monocrystalline and polycrystalline might exist. The percentage ratio of the three elements before and after the stability test was basically stable. Conclusion:Bismuth potassium citrate may have three crystal forms with the percentage of the three structure parts within a certain range, and the structure is relatively stable.

The efectienes of acpuncture for smoking cessation was systematically evaluated in this paper. By using computer retrieval in Chinese national knowledge infrastructure (CNKI), WANFANG database, VIP database, PubMed, ScienceDirect and Springer, the randomized controlled trials (RCTs) regarding acupuncture for smoking cessation from January of 1983 to December of 2013 were collected; by using Table of Standardized Report Factors for Acupuncture RCTs, each inclusive RCT was evaluated; and by using RevMan 5. 2 software, the Meta-analysis was performed. Totally 24 RCTs were included, involving 3084 cases of smoking. The result of literature quality assessment showed that the average score was 25. 71 points without low-quality RCT which had a score of less than 16 points. The Meta-analysis showed that acupuncture could significantly increase the short-time abstinence rate [RR=1. 48, 95% CI (1. 18,1. 84), Z=3. 47, P<0. 0005] and number of cigarettes smoked daily [RR=4. 35, 95% CI (2. 03, 6. 66), Z=3. 68, P<0. 001] and FTND [RR=2. 37, 95% CI (1. 88, 2. 86), Z= 9. 44, P<0. 00001], however, it could not increase the long-time abstinence rate [RR=1. 40, 95% Cl (0. 90, 2.17), Z=1. 49, P>0. 05]. Compared with other treatment, acupuncture has positive advantages on short-time abstinence rate, however, its effect on long-time abstinence rate needs to be verified by high-quality, large-sample and multi-center RCT in the future.

Objective To evaluate the vestibular function in patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Methods Seventeen CADASIL patients were recruited in the present study and 17 healthy volunteers served as control subjects. Electronystagmogram examinations including gaze nystagmus test, spontaneous nystagmus test, saccade test, pursuit test, optokinetic nystagmus test and caloric test were performed in the subjects. Results Neither patients nor controls had gaze nystagmus or spontaneous nystagmus. There was no difference in the latency and velocity of saccade movement between patients and controls. The accuracy of the saccade movement, the accuracy in leftward saccade, was significantly lower in CADASIL group compared with controls. The pursuit movement gains was also significantly lower in CADASIL group than in control group(G_L:0.79±0.08, G_R:0.76±0.12)(t=-3.739、-2.911,P <0.05) compared with controls(G_L:0.87±0.04, G_R:0.86±0.06).The optokinetic nystagmus gains were significantly decreased in CADASIL group(G_L:0.79±0.17,G_R:0.78±0.18)(t=-2.342、-2.335,P<0.05) compared with controls(G_L:0.90±0.08,G_R:0.89±0.09). The caloric test was performed in one CADASIL patient and the result revealed an incomplete fixing inhibition. CADASIL group was further divided into normal subgroup and abnormal subgroup based on the pursuit curve. The comparison between those two subgroups demonstrated a significant correlation between the pursuit movement and the symptoms of vertigo or dizziness(P<0.05). Conclusions The central vestibular function is impaired in CADASIL patients and the abnormal vestibular function is related to the symptom of vertigo or dizziness in CADASIL patients.
