Vertebral Artery Stenting for Acute Multiple Cerebral Infarctions Caused by Vertebral Artery Dissection After Massage: A Case Report.

Vertebral artery dissection is a rare pathology that causes ischemic stroke in young people. Cervical massage, especially improper pulling manipulation, is a cause of vertebral artery dissection. We present a case of 32-year-old woman who developed acute multiple posterior circulation ischemic cerebral infarctions as a result of left vertebral artery V4 segment dissection after receiving neck massage. She underwent emergency vertebral artery stent implantation at the site of the dissection. Symptoms were relieved the day after treatment. The patient recovered without adverse complications or endovascular restenosis in the following year.

Tributyltin oxide exposure impairs mouse oocyte maturation and its possible mechanisms.

Tributyltin oxide (TBTO) has been widely used as marine antifouling composition, preservative, biocide, and a stabilizer in plastic industry. Previous studies have indicated that TBTO can cause immunotoxicity as an environmental pollutant. However, little is known about its reproductive toxicity, especially on female oocyte maturation and the underlying mechanisms. In this study, mouse oocytes were cultured with different concentrations of TBTO in vitro, and several crucial events during meiotic maturation were evaluated. We found that the first polar body extrusion rate was significantly reduced, which reflected the disruption of meiotic maturation. The rate of abnormal spindle organization increased significantly, accompanied with a higher rate of chromosome misalignment. In addition, TBTO treatment increased reactive oxygen species generation markedly, which also accelerated the early-stage apoptosis. Moreover, heterogeneous mitochondrial distribution, mitochondrial dysfunction, and higher rate of aneuploidy were detected, which consequently disrupted in vitro fertilization. In conclusion, our results indicated that TBTO exposure could impair mouse oocyte maturation by affecting spindle organization, chromosome alignment, mitochondria functions, oxidative stress, and apoptosis.

[Tiaoshen acupuncture for primary insomnia: a pilot randomized controlled trial].

OBJECTIVE: To observe the effects of Tiaoshen (regulating the spirit) acupuncture on cognitive function and sleep quality in patients with primary insomnia (PI). METHODS: Sixty patients with PI were randomly divided into an observation group (30 cases, 2 cases dropped off) and a control group (30 cases, 2 cases dropped off, 1 case was excluded). The patients in the observation group were treated with acupuncture at Baihui (GV 20), Shenting (GV 24), Sishencong (EX-HN 1), and bilateral Benshen (GB 13), Shenmen (HT 7), Neiguan (PC 6), Sanyinjiao (SP 6). The patients in the control group were treated with shallow needling at non-effective points. Each treatment was provided for 30 min, once every other day, 3 treatments per week for 4 weeks. The Montreal cognitive assessment (MoCA), digit span test (DST), trail making test (TMT)-A, Pittsburgh sleep quality index (PSQI), and fatigue scale-14 (FS-14) were used to assess cognitive function and sleep quality before and after treatment, as well as in follow-up of 4-week after treatment completion. Correlation analysis was conducted between the differences in PSQI scores and differences in MoCA scores before and after treatment in the observation group. RESULTS: Compared with before treatment, the total score, visuospatial and executive function score and delayed memory score of MoCA as well as DST backward score were increased (P<0.01), while TMT-A time, PSQI and FS-14 scores were significantly reduced (P<0.01) after treatment and in follow-up in the observation group. Compared with before treatment, the PSQI score in the control group was reduced (P<0.01, P<0.05). After treatment and in follow-up, the observation group had significantly higher total score, visuospatial and executive function score, delayed memory score of MoCA, and DST backward score compared to the control group (P<0.05, P<0.01). In the observation group, the TMT-A time was significantly shorter than that in the control group (P<0.05, P<0.01), and the PSQI and FS-14 scores were significantly lower than those in the control group (P<0.01). In the observation group, there was a negative correlation between the difference in PSQI scores (post-treatment minus pre-treatment) and the difference in MoCA scores (post-treatment minus pre-treatment) (r=-0.481, P<0.01). A similar negative correlation was found between the difference in PSQI scores (follow-up minus pre-treatment) and the difference in MoCA scores (follow-up minus pre-treatment) (r=-0.282, P<0.05). CONCLUSION: Tiaoshen acupuncture could improve cognitive function, enhance sleep quality, and alleviate daytime fatigue in patients with PI. The improvement in cognitive function in patients with PI is correlated with the improvement in sleep quality.

[Effect of artemisia burning products on antioxidant enzymes in serum of SAMP8 mouse].

OBJECTIVE: To explore the anti-aging effect of artemisia burning products (ie. smoke of moxibustion) and its proper intervention parameters. METHODS: According to factorial experiment design, 70 SAMP8 mice were randomly divided into one model group (group M) and 6 intervention groups: low concentration with 15 min group (group A1), low concentration with 30 min group (group A2), middle concentration with 15 min group (group B1), middle concentration with 30 min group (group B2), high concentration with 15 min group (group C1), high concentration with 30 min group (group C1). There were 10 cases in each group. Ten age-matched SAMR1 mice were used as normal group (group Z). All the mice in the 6 intervention groups were fumed with artemisia burning products of different concentration and time. The content of serum malondialdehyde (MDA), the activity of superoxide dismutase (SOD) and glutathione reductase (GSH-Px) were tested. RESULTS: MDA content in group M was significantly higher than that in group Z (both P < 0.05), while SOD and GSH-Px activity were significantly lower in group M than that in group Z (both P < 0.05). Results of MDA, SOD and GSH-Px in 6 intervention groups were either of no statistically significant differences, or better than that in group M. Among 6 intervention groups, results of MDA and GSH-Px were better in group B1, while the result of SOD was better in group B2. Time factor didn't make any difference, while concentration of artemisia burning products is meaningful. As to SOD and GSH-Px, there's a strong interaction between the two factors. CONCLUSION: With certain concentration and time period, the intervention of artemisia burning products can exert anti-aging effect by increasing antioxydative capability and reducing metabolites of free radicals. Middle concentration and 30 minutes are recommended when intervened with artemisia burning products.
