ObjectiveTo investigate the antiviral effect of siRNA on herpes simplex virus type 2 (HSV-2) in vitro.MethodsDifferent siRNA duplexes targeting HSV-2 VP16 and DNA polymerase genes were designed and chemically synthesized.The antiviral effect of siRNA duplexes was evaluated by virus yield reduction assay.In detail,Vero cells cultured in 24-well plates were transfected with different siRNAs 4 hours before(preventive effect experiment) or 1 hour after(therapeutic effect experiment) the inoculation with HSV-2(0.02 to 0.05 plaque forming unit/cell).After additional culture for 40 to 48 hours,the expression of target genes in Vero cells was measured by real-time quantitative reverse transcription(RT)-PCR.Results Both the siRNA duplex VP2-1 targeting HSV-2 VP16 and DP2-1 targeting DNA polymerase gene resulted in a remarkable decrease in viral titer by about 1 log10 in both the preventive and therapeutic effect experiment.As the preventive effect experiment showed,the expression of HSV-2 VP16 mRNA was decreased markedly by 58.6％ and 79.5％ by VP2-1,respectively,and that of HSV-2 DNA polymerase mRNA by 59.8％and 77.4％ by DP2-1,respectively,at 6 and 12 hours after the infection.ConclusionsThe siRNA duplexes targeting HSV-2 VP16 and DNA polymerase genes could inhibit the proliferation of HSV-2.Hence,HSV-2 VP16 and DNA polymerase genes may serve as the target genes of RNA interference to inhibit HSV-2 replication.

To explore the effect of Kudiezi injection on renal function in the real world, in order to provide the basis for the clinical medication safety. Patient aged between 18-80 were selected from 18 large hospitals information system (HIS) databases established by clinical research institute for basic traditional Chinese medicine of China academy of Chinese medical sciences. The patients who were treated with Kudiezi injection (24 225 cases) were defined as the exposed group, whereas those who were not treated with Kudiezi injection (14,191 cases) were defined as the non-exposed group. The propensity score method was used to balance the confounding factors. Classic logistic regression, GBM weighted propensity score logistic regression, GBM propensity score weighted logistic regression with covariate and sensitivity analysis were adopted to study the effect of Kudiezi injection on renal function. The results showed no significant difference in the possibility in abnormality in serum creatinine (Scr) (P = 0.940, 0.679, 0.834) and urea nitrogen (BUN) (P = 0, 0.045, 0.164) between both groups. Therefore, the existing data indicated no damage of Kudiezi injection on renal function. Because this study is a retrospective study based on the real world, there may be unknown confounding factors and potential bias. Therefore, further studies shall be conducted to monitor whether Kudiezi injection causes damage on renal function, in order to ensure the clinical medication safety.

Objective To investigate the different expressions of pathological tissue and serum microRNAs (miRNAs)in Hirschsprung disease(HSCR). Methods Pathological colon tissues and serum samples were obtained from 52 confirmed HSCR cases respectively by surgery and pathology and from 52 matched controls,respectively. An initial screening of the tissues and serum microRNA expression were performed through TaqMan Low Density Array. The candidate tissue and serum miRNAs were validated by quantitative real - time - PCR in the 20 paired array samples and extra 32 paired samples after the integration of the screening result. The bioinformatical software online including miR-base,Target Scan,PicTar and MiRanda were used to predict the target mRNA of the consistent microRNAs in the tis-sues and the serum. Results Compared with the controls,47 microRNAs were differently expressed in HSCR tissues, including 17 up - regulated miRNAs and 30 down - regulated miRNAs;32 upregulated miRNAs were also detected to be differently expressed in the HSCR serum. Among these microRNAs,miR - 218 - 1 and miR - 885 - 5p were identi-fied to have a consistent significant different expression in both tissues and the serum,which were validated as high -expressed in microarray samples and expanded 32 paired samples(miR - 218 - 1:tissue array 0. 017 58 ± 0. 002 29 vs 0. 003 37 ± 0. 000 50,P ﹤ 0. 001;tissue expanded expression 0. 013 53 ± 0. 001 74 vs 0. 004 43 ± 0. 000 60,P ﹤0. 001. miR - 885 - 5p:tissue array 0. 000 30 ± 0. 000 11 vs 0. 000 04 ± 0. 0000 08,P = 0. 027 6;tissue expanded ex-pression 0. 004 59 ± 0. 000 16 vs 0. 000 04 ± 0. 000 01,P = 0. 014 5. miR - 218 - 1:serum array 0. 769 60 ± 0. 285 50 vs 0. 045 14 ± 0. 015 07,P = 0. 015 5;serum expanded expression 1. 151 00 ± 0. 430 00 vs 0. 023 07 ± 0. 003 81,P =0. 008 7. miR -885 -5p:serum array 1. 595 00 ±0. 441 70 vs 0. 169 40 ±0. 034 46,P =0. 001 2;serum expanded expres-sion 1. 689 00 ±0. 453 00 vs 0. 146 10 ± 0. 031 24,P = 0. 001 2). Specifically,the target genes of these 2 microRNAs were RET,PLAG1 and NeuroD1,which had been reported to be directly related to HSCR. Conclusions Significantly dif-ferential expressed miRNAs exist in the pathological tissue and the serum of HSCR. MiR - 218 - 1 and miR - 885 - 5p, which showing consistent differential expression,may be involved in the pathogenesis of HSCR.

Objective To explore the role of cognitive rehabilitation in improving cognitive dysfunction of patients with multiple sclerosis (MS). Methods Forty patients with MS, admitted to our hospital from September 2008 to October 2010, were chosen; neuropsychological tests were employed to evaluate the neurobehavioral cognitive status, executive capacity and overall cognitive function, and patients with MS were treated with cognitive rehabilitation. The differences of neurocognitive function scores in these patients before and after treatment were compared. Results The results showed that the scores of full intelligence quotient (FIQ) after therapy was higher than those before therapy (P＜0.05); the neurological status of behavior was improved, and the scores of memory, language, dealing with information, and judgment after therapy were significantly higher than those before treatment (P＜0.05);significant difference on implement function was also noted between that before and after therapy (P＜ 0.05). Conclusion The rehabilitation could improve the impairment of cognitive function in patients with MS, including IQ, neurobehavioral cognitive status, executive functions, which is meaningful in clinical application for treating and bettering the living conditions in patients with MS.

This study aimed to examine the preparation of cationic lipid microbubble (CLM), and evaluate its physical and chemical properties and toxicity, measure the gene transfection efficiency by ultrasound triggered microbobble destruction (UTMD) in combination with CLM. The CLM was prepared by the method of the thin film hydration, and its morphology was observed under the electron microscopy at 1st, 3rd, 7th, 10th, and 14th day after preparation, respectively. The size, Zeta potential and stability of CLM were tested. The acute toxicity of CLM was assessed. The green fluorescent protein gene (EGFP) transfection efficiency was evaluated. The experiment grouping was as follows: naked plasmid group (P group), ultrasonic irradiation plus naked plasmid group (P-US group), naked plasmid plus CLM group (P-CLM group), naked plasmid plus ultrasound and CLM group (UTMD group). The expression of EGFP was detected by fluorescent microscopy and flow cytometry. The results showed that CLMs were spherical in shape, with the similar size and good distribution degree under the light and electron microscopies. The size of CLMs was varied from 250.4±88.3 to 399.0±99.8 nm and the Zeta potential of CLMs from 18.80±4.97 to 20.1±3.1 mV. The EGFP expression was the strongest in the UTMD group, followed by the P-CLM group, P-US group and P group. Flow cytometry results were consistent with those of fluorescent microscopy. The transfection efficiency was substantially increased in the P-US group, P-CLM group and UTMD group as compared with that in the P group, almost 7 times, 10 times and 30 times higher than that in the P group respectively. It is suggested that CLMs prepared by the method of thin film hydration are uniform in diameter, and proved non-toxic. UTMD combined with CLM can significantly increase the transfection efficiency of EGFP to targeted cells.
