Tegument protein VP22 is encoded by Pseudorabies Virus (PRV) UL49. To identify the nuclear localization signals of UL49, it is necessary to determine the transport mechanism and biological functions of the VP22 protein. In this study, we identified two nuclear localization signals from UL49, NLS1 (5RKTRVA ADETASGARRR21) and NLS2 (241PGRKGKV247). The functional nuclear localization signal (NLS) of UL49 was identified by constructing truncated or site-specific UL49 mutants. The deletion of both NLS1 and NLS2 abrogated UL49 nuclear accumulation, whereas the deletion of NLS1 or NLS2 did not. Therefore, both NLS1 and NLS2 are critical for the nuclear localization of UL49. And our resuts showed that NLS2 is more important in this regard.

AlM:To study the treatment effect of traditional Chinese medicine in the treatment of high myopia macular hemorrhage, using Chinese medicine etiology and pathogenesis, syndrome differentiation treatment, and provide the basis for the clinical treatment. METHODS: Eighty patients ( 135 eyes ) with high myopia macular hemorrhage were selected in the hospital from January 2012 to september 2014 as treatment group, and applied traditional Chinese medicine treatment. Forty-five patients (64 eyes) with the same period, as the control group, received routine western medicine treatment. After 1mo treatement, the treatment effect and vision improvement situation of two groups were observed, and after 6mo follow-up, the relapse was observed.RESULTS: The total effective rate of treatment group was 85. 19% (115/135), higher than the control group 78. 13% (50/64) (P<0. 05). The average corrected visual acuity of treatment group was 0. 48±0. 11, higher than the control group 0. 36 ± 0. 09, the difference was statistically significant (P<0. 05). The average diopter and macular bleeding scope of the treatment group were -9. 81±0. 85D and 0. 51 ± 0. 27PD, lower than the control group -10. 76 ± 0. 91D and 0. 78 ± 0. 23PD, the differences were statistically significant ( P < 0. 05 ). The eye ground hemorrhage absorption time of treatment group was 25. 34±2. 28d, less than the control group 29. 72 ± 2. 13d, the difference was statistically significant (P<0. 05). The bleeding again of the control group 7. 81% ( 5/64 ), higher than the treatment group was 5. 19% (7/135), the difference was statistically significant (P<0. 05).CONCLUSlON: Evidence-based treatment of traditional Chinese medicine for high myopia macular hemorrhage has good clinical effect, can shorten the treatment time, and is beneficial to the recovery of postoperative vision, worthy of clinical popularization and application.

Objective To investigate the effects of Mycobacterium vaccae vaccine on immunological function and clinical character in elderly patients with stable chronic obstructive pulmonary disease (COPD). MethodsA total of 100 elderly patients with stable COPD were randomly divided into immunotherapy group (group A, n= 50) and non-immunotherapy group (group B, n= 50), and normal control group (group C, n = 50). The levels of peripheral blood T-lymphocyte subsets (CD3+ , CD4+, CD8+ , CD4+/CD8+ ratio), natural killer cells (NK cells), immunoglobulins (IgG, IgA, IgM) and cytokines (IL-6, IL-8, TNF-a) were measured respectively before and after therapy. Group A and B were followed up for 1 year, then the times of acute outbreak and hospitalization of patients in the two groups were also compared. Results The levels of CD4 + ,CD4+/CD8+ ratio and NK cells in group A, B were significantly lower before therapy (P＜0. 05～0. 01＝, and the levels of IL-6, IL -8, TNF-a and IgA were significantly higher than in group C (P＜0. 01＝. After treatment with Mycobacterium vaccae vaccine in group A, the levels of CD4+ , CD4+/CD8+ ratio and NK cells were significantly higher (P＜0. 05-0. 01＝ and IL-6, IL-8, TNF-a and IgA were significantly lower than before treatment (all P＜0. 01＝. These levels showed no significant changes in group B after treatment (P＞0. 05). After 1-year follow-up, the times of acute outbreak and hospitalization on patients were statistically lower in group A than in group B (P＜ 0. 01 ).ConclusionsMycobacterium vaccae vaccine can improve cellular immunity function and reduce the times of acute outbreak and hospitalization in patients with stable COPD, so it has a higher clinical application value.

OBJECTIVETo explore the effect of Dandi Tablet (DDT), a TCM preparation for tonifying Shen and activating blood circulation, on blood lipids and sex hormones in women of postmenopausal stage.

METHODSSeventy-three women were randomly divided into two groups. The 46 subjects in the DDT group were treated with DDT (consisted of prepared Rehmannia Root 24 g, Dogwood Fruit 9 g, Poria 9 g, Water-plantain 9 g, Tuber Peony bark 9 g, Chinese Yam 12 g and Red Sage 15 g, etc.) twice a day, 4 tablets each time. The 27 subjects in the control group were treated with nylestriol (each tablet contains 2.5 mg of 17 alpha-ethynylestriol-3-cyclopentyl ether) 5 mg every month, for 3 successive months. Levels of blood lipids, including total cholesterol (TC), triglyceride (TG), high and low density lipoprotein cholesterol (HDL-C, LDL-C), apoprotein A and B (apoA, apoB) and sex hormones, including follicular stimulating hormone (FSH) and estradiol (E2) were determined before and after treatment.

RESULTSCompared with pre-treatment, after treatment, levels of TC/HDL-C and FSH significantly lowered, HDL-C and E2 increased in both groups (P < 0.05 or P < 0.01), levels of TG lowered and apoA increased significantly in the DDT group (P < 0.05).

CONCLUSIONDDT has the effect of elevating levels of estrogen and improving blood lipid metabolism, therefore shows a coronary heart disease preventive effect in women of postmenopausal stage.

OBJECTIVETo investigate the effect of early high-loading-dose tirofiban on platelet activity for patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention.

METHODSA total of 120 acute STEMI patients were treated with 300 mg aspirin and 600 mg loading dose clopidogrel and randomized to high-dose tirofiban (25 µg/kg bolus followed by 0.15 µg×kg(-1)×min(-1) infusion for 36 hours, n = 40), standard-dose tirofiban (10 µg/kg bolus followed by 0.15 µg×kg(-1)×min(-1) infusion for 36 hours, n = 40) or control (no tirofiban, n = 40) before angiography. Inhibition of platelet aggregation (IPA) was assessed before angiography, at 10 min and 24 hours after tirofiban infusion, and at 12 and 24 hours after stopping tirofiban infusion by the thrombelastography assay.

RESULTSThere was no significant difference in baseline of IPA between the 3 groups (P > 0.05). IPA was significantly higher in high-dose tirofiban group compared with standard-dose tirofiban and no tirofiban group at 10 minutes after tirofiban infusion [(84.2 ± 12.0)% vs. (67.8 ± 26.8)% and (31.5 ± 21.9)%, all P < 0.01]. At 24 hours after tirofiban infusion, the IPA of high-dose and standard-dose tirofiban was similar [(93.0 ± 9.8)% vs. (88.5 ± 18.1)%, P > 0.05] and was significantly higher than no tirofiban group [(40.4 ± 22.8)%, all P < 0.01]. IPA was similar at 12 and 24 hours after stopping tirofiban use among the 3 groups (all P > 0.05). The maximum amplitude of high-dose tirofiban and standard-dose tirofiban groups at different time points was similar (all P > 0.05), and maximum amplitude in both tirofiban groups was significantly lower than in no tirofiban group at 10 min [(47.2 ± 7.6) mm and (50.0 ± 9.8) mm vs. (57.7 ± 6.5) mm, all P < 0.01] and at 24 hours after stopping tirofiban infusion [(54.6 ± 5.6) mm and (54.3 ± 9.0) mm vs. (59.6 ± 4.0) mm, all P < 0.01].

CONCLUSIONEarly use of high-loading-dose of tirofiban on top of 600 mg loading dose clopidogrel is more efficient on inhibiting platelet activity than standard dose of tirofiban in patients with acute STEMI undergoing primary primary percutaneous coronary intervention.

Multi-Efficacy of One Drug (MEOD) refers to the traditional Chinese medicines (TCM) with diverse efficacies.MEOD,one of the important characteristics of TCM,is regarded as the basis of clinical rational drug use.However,there have been few reports on the MEOD research so far.In this paper,with rhubarb selected as a typical model drug,metabolomics and network pharmacology analysis are integrated to investigate the mechanisms of MEOD with the employment of the two animal models of constipation and jaundice.Then,the biological target network of MEOD is established for promoting the precision of the quality control and clinical use of TCM.

To learn about the economic studies on traditional Chinese medicines in domestic literatures, in order to analyze the current economic assessment of traditional Chinese medicines and explore the existing problems. Efforts were made to search CNKI, VIP, Wanfang database and CBM by computer and include all literatures about economic assessment of traditional Chinese medicines published on professional domestic journals in the systematic assessment and quality evaluation. Finally, 50 articles were included in the study, and the systematic assessment and quality evaluation were made for them in terms of titles, year, authors' identity, expense source, disease type, study perspective, study design type, study target, study target source, time limit, cost calculation, effect indicator, analytical technique and sensitivity analysis. The finally quality score was 0.74, which is very low. The results of the study showed insufficient studies on economics of traditional Chinese medicines, short study duration and simple evaluation methods, which will be solved through unremitting efforts in the future.

In this study, ITS2 barcode was used to identify Bupleurum chinense and B. longiradiatum. The ITS2 regions of 48 samples were amplified and sequenced. The sequences obtained above were aligned and the K2P distances were calculated. We used three methods, BLAST1, nearest distance and phylogenetic tree (NJ-tree), to test the identification ability. The results showed that the maximum intraspecific genetic distance of B. chinense was 0.013, and the minimum interspecific genetic distance between B. chinense and B. longiradiatum was 0.049. The NJ-tree can easily identify B. chinense and B. longiradiatum. Therefore, the ITS2 barcode is suitable to identify B. chinense and B. longiradiatum.
