Objective To study the effect of remote limb isehemic postconditioning (RLIPC) on posterior circulation ischemia vertigo (PCIV). Methods Seventy patients with PCIV, admitted to our hospital from January 2013 and June 2014, were randomly divided into control group and therapy group (n=35). The patients of control group were treated with routine medicine, and those of therapy group were treated with RLIPC and routine medicine. Before and after treatment, dizziness assessment rating scale (DARS) and dizziness handicap inventory (DHI) scale were used to evaluate the changes of manifestations; peak systolic velocity (PSV) and end diastolic velocity (EDV) of vertebra artery (VA) were evaluated by colour doppler ultrasound. Results Before treatment, no significant differences on DARS and DHI scores were noted between the two groups (P>0.05); after treatment, , the DARS and DHI scores in the therapy group were 26.03±4.24 and 60.91±10.15, respectively, which were significantly decreased as compared with those in the control group (28.80±5.16 and 68.11±12.44, t=2.388 and 2.584, P=0.000); PSV and EDV of VA in the therapy group were 49.97±7.69 and 16.90±2.80, respectively, which were significantly increased as compared with those in the control group (47.31±7.47 and 15.12± 2.74, t=-2.505 and-2.631, P=0.015 and 0.011). Conclusions RLIPC could alleviate the symptoms of PCIV, which might be related to increased blood flow of VA. RLIPC is simple and safe, and can be used in the treatment of PCIV.

Objective:To observe any effect of supplementing conventional rehabilitation training with repeated transcranial magnetic stimulation (rTMS) in the treatment of lumbar disc herniation (LDH).Methods:Seventy-two LDH patients were randomly divided into an rTMS group ( n=24), a training group ( n=24), and a combined group ( n=24). The rTMS group received 2Hz rTMS at an intensity of 80% resting motor threshold with a total of 1000 pulses, the training group was given Mackenzie therapy and lumbar core muscle stability training, while the combined group was provided with both. Each group was treated once a day, 6 times a week for 8 weeks. The participants rated their pain using a visual analog scale (VAS), and the Oswestry dysfunction index (ODI) was also used to evaluate the degree of pain and dysfunction in all three groups before and right after the treatment, as well as 8 weeks later. After the treatment, its therapeutic effect was evaluated using the improved Macnab standard. Each patient was followed up for 12 months and any recurrence was recorded. Results:Before treatment there was no significant difference in average VAS ratings or ODI scores among the three groups. Afterward, pain and dysfunction were relieved significantly in all three groups. Compared with the rTMS group, the average VAS rating in the training group was significantly higher and the average ODI score was significantly lower after the treatment and during the follow-up. Moreover, the average VAS rating and ODI score of the combined group were significantly lower than those in the other two groups after the treatment and during follow-up. The total effectiveness rate in the rTMS group was assessed as 62.5% compared with 95.8% in the training group and 100% in the combined group-a significant difference for the rTMS group. Follow-up showed that the recurrence rates of the rTMS group, training group and combined group were 37.5%, 25% and 8.3%, respectively-a significant difference in the case of the combined group.Conclusion:rTMS combined with rehabilitation training can relieve pain, improve lumbar function and reduce the recurrence of LDH.

ObjectiveTo analyze the genetic characteristics of the hemagglutinin （H） gene of measles virus （MeV） in Shanghai， 2001‒2018. MethodsNasopharyngeal swab specimens were collected from suspected measles cases reported in Shanghai from 2001 to 2018， and the isolation of measles virus was conducted with Vero/hSLAM cell line. RT-PCR amplification and sequencing were conducted after RNA extraction to analyze the genetic characteristics of the complete H gene. ResultsIn total， 5 665 nasopharyngeal swab samples were collected by suspected measles case surveillance from 2001 to 2018， and 1 394 measles virus strains were isolated. The homology of nucleotide acid and amino acid among 349 representative measles virus isolates was 87.4%‒100.0% and 85.1%‒100.0%， respectively. The homology of nucleotide acid and amino acid between representative measles virus isolates and China vaccine strain （S191） was 85.7%‒100.0% and 84.1%‒100.0%， respectively. All the sub-genotype H1a MeV isolates had an amino acid substitution （Ser240Asn）， which removed a predicted N-linked glycosylation site. ConclusionMost of the MeV isolates are sub-genotype H1a analyzed based on H gene， which are identical to those of the N gene. The predicted amino acid sequences of the H protein are relatively conserved at most of the functionally significant amino acid positions.

【Objective】 To explore the effect of Genistein on the proliferation and cell cycle regulation of ovarian cancer cells. 【Methods】 Ovarian cancer OVCAR-5 cells were treated with Genistein. Cell counting and MTS assays were performed to determine the alterations of cell proliferation. Real-time PCR and Western blotting were conducted to examine the expression changes of key cell cycle regulators. 【Results】 Genistein significantly promoted the proliferation and viability of OVCAR-5 cells. After Genistein treatment, cellular mRNA and protein expression levels of cell cycle activators such as PCNA, Cyclin D1 and CDK4 were increased, but those of cell cycle inhibitors such as p21 and p27 were decreased. 【Conclusion】 Genistein can upregulate the proliferation and G1-S transition of ovarian cancer OVCAR-5 cells. The discrepancy may be caused by diverged experimental conditions and/or different ER expression patterns of cell lines. The findings may provide basic information for in-depth analysis of the role(s) and mechanisms by which genistein confers its effect on ovarian cancer cells.
