OBJECTIVETo compare the difference in the clinical efficacy on primary trigeminal neuralgia (PTN) between the comprehensive therapy of electroacupuncture (EA) at qi streets acupoints combined with spinal regulation method and medication with carbamazepine (CBZ).

METHODSSixty patients were randomized into a comprehensive therapy group (30 cases) and a medication group (30 cases). In the comprehensive therapy group, the acupoints at qi streets on the head such as Taiyang (EX-HN 5) and Sishencong (EX-HN 1) and those at qi streets on the chest and abdomen such as Shenshu (BL 23), Zhongwan (CV 12) and Guanyuan (CV 4), etc. were selected. After arrival of qi, EA was attached on 2 to 4 groups of acupoints. After acupuncture, the spinal regulation method was applied. This comprehensive therapy was given once a day. In the medication group, CBZ was used for oral administration, 100 mg at the first time, twice a day, and 400 to 600 mg each day as the maintenance dose. Separately, before and after treatment, in 2 and 6 months in follow-up, pain rating index (PRI), life satisfaction index B (LSI-B) and hamilton depression scale (HAMD) were adopted to evaluate comprehensively the clinical efficacy in the two groups and compare the adverse reaction during the treatment between the two groups.

RESULTSAfter treatment, the curative and markedly effective rate in the comprehensive therapy group was 76.7% (23/30), which was better than 63.3% (19/30) in the medication group (P < 0.01). The difference in PRI was not significant after treatment between the two groups (all P > 0.05). In 2 and 6 months follow-up, PRI grade in the comprehensive therapy group was superior to that of the medication group (both P<0. 05). After treatment and in follow-up, HAMD score was all reduced in the two groups (P < 0.01, P < 0.05) and the result in follow-up in the comprehensive therapy group was significant as compared with that in the medication group (all P<0. 05). After treatment, LSI-B score was increased obviously in the two groups (all P < 0.05) and the result in the comprehensive therapy group was better than that in the medication group (P < 0.05). The incidence of adverse reaction in the comprehensive therapy group was 16.7% (5/30), which was lower than 30.0% (9/30, P < 0.01) in the medication group.

CONCLUSIONThe comprehensive therapy of EA at qi streets acpoints combined with spinal regulation method achieves the long-term efficacy on PTN as compared with oral administration of CBZ in terms of the improvement of psychological condition, analgesia and life quality. It is the safe, effective and stable therapy.

Three candidate antisense target sites of mouse Fas gene were screened by PARASS (poly-A anchored RNA accessible sites screening) technology. They were target at Fas gene 297nt-317nt, 618nt- 638nt and 662nt-682nt. Antisense oligos (A1, A2 and A3) and DNAzymes (D1, D2, and D3) for every target site were designed and synthesized. In vitro, the validation of the sites were judged by antisense oligos included RNase H splicing and the DNAzyme degradation. The results indicated that A1, A2 and A3 introduced RNase H degradation. DNAzymes D1, D2 and D3 cleaved Fas mRNA effectively. Neither degradation observed in antisense oligo RNase H group in non-target site (1211-1231nt) and 2 bases mismatched of A3, nor splicing occurred in DNzyme group in non-target site ( 1211-1231nt) and 2 bases mismatched of D3. Site 2 and 3 were at the same positions with those of ISIS Pharmaceuticals. The effective antisense oligos and DNAzymes for Fas gene could be used for the research subsequently.

Objective To determine the effect of paired immunoglobulin-like receptor B (PirB) on growth of retinal ganglion cells (RGCs) in vitro.Methods Expression of PirB in RGCs isolated from wild-type C57 BJ/6 mice was measured by immunofluorescence.Real-time PCR and Western blot were performed to detect PirB expressions in RGCs cultured for 1,3,5,7 and 9 days.Primary cultured RGCs were left untreated as controls,transfected with lentiviral-delivered PirB RNAi as Group A,lentiviral-delivered NgR RNAi as Group B,lentiviral-delivered PirB RNAi plus ciliary neurotrophic factor (CNTF) as Group C,lentiviral-delivered NgR plus CNTF as Group D,and only CNTF as Group E.Growth and development of RGCs were evaluated by MTT assay and morphological analysis.Results Immunofluorescence confirmed expression of PirB in RGCs,with its mRNA and protein levels changing from increase at first to decrease later with time,up to peak at days 5 and 7.PirB and NgR were respectively down-regulated in Groups A and B.Viability of RGCs was improved in Group A compared with control group [(40.2 ± 5.3) μm vs (29.1 ± 3.8) μm at day 3 ; (72.2 ± 4.2) μm vs (52.3 ± 8.2) μm at day 5,both P ＜ 0.05].By contrast,no significant difference was found in viability of RGCs among Groups B,D and E when compared to control group (P ＞ 0.05).Growth of RGCs between Groups A and C revealed insignificant difference (P ＞ 0.05).Conclusion Knockdown of PirB is beneficial for the growth of RGCs,suggesting a novel method to treat optic nerve injury.

Objective: To evaluate the correlative risk factor of culprit lesion plaque composition in patients with acute coronary syndrome (ACS).
Methods: A total of 55 ACS patients with 55 culprit vessels were divided into 2 groups:Unstable angina group, n=40 and AMI group, n=15. Coronary angiography (CAG) was conducted in all patients, the minimal lumen area and plaque burden at the minimal lumen area and the largest necrotic core were examined. Intravascular ultrasound with virtual histology (IVUS-VH) were performed to calculate the percentages of necrotic core area (NC%), dense calcium (DC%), ifbro-fatty area (FF%), ifbrous area (FI%) and to calculate the remodeling index. Plasma levels of matrix metalloproteinase-9 (MMP-9), oxidative low density lipoprotein (Ox-LDL) and hypersensitive c-reactive protein (hs-CRP) were also compared between 2 groups.
Results: In AMI group and UAP group, NC%at minimal lumen area were (27.90 ± 9.72)%and (19.41 ± 11.53)%, t=-2.533, P=0.014;NC%at the largest necrotic core were (39.09 ± 8.82)%and (31.99 ±1 2.35)%, t=-2.032, P=0.047;plasma levels of MMP-9 were (14.63±2.71) μg/L and (12.65±2.72) μg/L, t=-2.411, P=0.019;Ox-LDL were (196.21±25.89) μg/L and (159.57±33.39) μg/L, t=-3.832, P=0.001;hs-CRP were (1.57±1.93) mg/L and (0.31±0.33) mg/L, t=-2.514, P=0.024 respectively. Plaque composition was not related to plasma levels of MMP-9, Ox-LDL and hs-CRP. In the largest necrotic core of cruprit lesion and the minimal lumen area, MLA were (5.25±2.15) mm2 and (3.45±1.07) mm2, t=-6.348, P=0.001;NC%were (33.93±11.85)%and (21.73±11.62)%, t=-8.752, P=0.001 respectively.
Conclusion: ①Among ACS patients, AMI patients had the larger necrotic core area at cruprit lesion and higher MMP-9, Ox-LDL and hs-CRP.②There was no largest necrotic core composition at the minimal lumen area in the same cruprit lesion.③Plaque composition was not related to MMP-9, Ox-LDL and hs-CRP.

The influence of low tube voltage in dual source CT (DSCT) coronary artery imaging on image quality and radiation dose and its application value in clinical practice were investigated. Totally, 300 cases of chest pain with low body mass index (BMI <18.5 kg/m(2)) subjected to DSCT coronary artery imaging were prospectively enrolled. The heart rate in all patients were greater than 65/min. The retrospective ECG gated scanning mode and simple random sampling method were used to assign the patients into groups A, B and C (n=100 each). The patients in groups A, B and C experienced 120-, 100-, and 80-kV tube voltage imaging respectively, and the image quality was evaluated. The CT volume dose index (CTDIvol) and dose length product (DLP) were recorded, and the effective dose (ED) was calculated in each group. The image quality scores and radiation doses in groups were compared, and the influence of tube voltage on image quality and radiation dose was analyzed. The results showed that the excellent rate of image quality in groups A, B and C was 95.69%, 94.72% and 96.33% respectively with the difference being not statistically significant among the three groups (P>0.05). The CTDIvol values in groups A, B and C were 51.35±12.21, 21.28±7.13 and 6.34±3.34 mGy, respectively, with the difference being statistically significant (P<0.05). The ED values in groups A, B and C were 9.27±1.63, 4.56±2.29 and 2.29±1.69 mSv, respectively, with the difference being statistically significant (P<0.05). It was suggested that for the patients with low BMI, the application of DSCT coronary artery imaging with low tube voltage can obtain satisfactory image quality, and simultaneously, significantly reduce the radiation dose.
