Objective To investigate the effects of different doses of dexmedetomidine used in SEP and MEP monitoring in patients undergoing neurosurgery. Methods Eighty patients undergoing neurosurgery receiving SEP and MEP monitoring were randomly divided into 4 groups(n = 20 each):group C,group D1,group D2 and group D3. In groups D1 ,D2 and D3 ,dexmedetomidine 0.5 μg/kg was infused over 10 minutes before anesthesia induction,and then was infused at a rate of 0.1,0.3 and 0.5μg/(kg·h)respectively toward the end of operation. Group C received the equal volume of normal saline. HR ,MAP and BIS were recorded at admission to the operating room(T1),skin incision(T2),when the muscle relaxants were stopped(T3)and 50 minutes later(T4). The current intensity and the time when first MEP was induced after muscle relaxant was stopped ,the amplitudes and latencies of SEP(N20-P25,N20)and MEP on thenar muscle at T4,the total consumption of propofol,and development of adverse affects were also recorded. Results Compared with groups C and D1,HR and MAP were decreased at T2-T4 in groups D2 and D3(P<0.05). The amount of propofol consumed were lower in groups D2 and D3 than in groups C and D1(P < 0.05). The current intensity inducing MEP was lower and the amplitude of MEP at T4 was higher in group D2 than in groups C,D1 and D3,and the situation was same in group D3 than in group C (P<0.05). No significant change was found in the other parameters in groups C ,D1 ,D2 and D3(P>0.05). Conclusion Dexmedetomidine infused at 0.3 μg/(kg · h) after infusion of a loading dose of 0.5 μg/kg could improve monitoring quality of MEP through reducing the amount of propofol consumed ,have less inhibition on MEP than other groups,have no obvious effects on SEP,andmaintain hemodynamic stability.

Objective To investigate the effect of nerve growth factor (NGF) on the bone induction of recombinant human bone morphogenetic protein-2 (rhBMP-2) through local application of NGF in the osteoinductive process of BMP. Methods Thirty-six ICR mice were divided into the experimental group and control group at random, and rhBMP-2/collagen composite was implanted into the right thigh muscle pouch of each group. NGF or vehicle was daily injected into the implanted sites of BMP, respectively, for 7 days starting from the third day after surgery. At d10, d20 and d30 after implantation, new bone formation was measured radiographically, biochemically and histologically to compare the osteogenetic capacity of the two groups. Results In both groups, new bone formation was found at d10. However, there was significantly more new bone in the experimental group according to histological and radiographic examinations. At d10 and d20, alkaline phosphatase activity of the local tissue in the experimental group was significantly greater than that in the control group, and calcium and phosphonium contents of samples were also greater in the experimental group. Arrangement of collagen fibers became more regular in the experimental group than that in the control group. Conclusion NGF possesses synergistic effect on ectopic bone formation induced by rhBMP-2.

CONCLUSION: There is a significant correlation between voriconazole's mental abnormity and trough concentration.

Objective To investigate the effect of tamoxifen on pituitary tumor transforming gene ex-pression in C6 cell and tumor growth of glioma in vivo. Methods Animal models were established on 32 SD rats with C6 cells of glioma. The rats bearing with C6 glioma were divided into 4 groups randomly, which were treated without tamoxifen or with different doses of tamoxifen(0. 02 mg · kg-1 · d-1, 0. 2 mg · kg-1 · d-1, 2mg · kg-1 · d-1) once a day for 20 days. The dimension of tumors were measured, the tumor inhibition rates were caculated, and living state of the rats were observed. The expression of PTTG mRNA was detected by RTPCR. Results All kinds of doses of tamoxifen could inhibit the tumors growth in rats with C6 glioma, and the tumor volume were reduced by 47.6%, 35.5% and 21.2% in the high-, middle-and low-dose groups respec-tively, there were significantly differences among the 4 groups ( P < 0. 05 ). Low-, middle- and high- dose of tamoxifen all could inhibit the expression of PTTG mRNA, and there were significantly differences among the 4 groups in PTTG mRNA expression ( P < 0. 05 ). Conclusion Tamoxifen can inhibit PTTG expression and the growth of glioma cell line C6 in vivo significantly in dose-dependent manner, which provides a theory basis for clicinal use of tamoxifen in patients with gliomas.

Objective To investigate the relationship of serum levels of homocysteine, cystain C and uric acid with ca?rotid atherosclerosis in H-type hypertension patients. Methods A total of 132 H-type hypertension patients were collected to be studied. Their carotid intima-media thickness (IMT) was measured by Doppler ultrasonography. And according to the result of carotid artery atherosclerosis, all patients were divided into normal cIMT group (n=40),thickened cIMT group (n=43) and plague formation group (n=49). Their serum Hcy, Cyst-C, UA, blood glucose, blood lipid, blood urea nitrogen and se?rum creatinine were compared among three group and their relationship with cIMT were analyzed. Logistic regression was used to screen risk factors for carotid atherosclerosis. Results There was no significant difference in serum levels of blood glucose,blood urea nitrogen, creatinine, serum creatinine (Scr), triglyceride (TG), total cholesterol (TC), low density lipppro?tein cholesterol (LDL-c) among these three groups (P>0.05). The level of high-density lipoprotein (HDL-c) in thickened cIMT group was higher than that in plague formation group, and lower than normal cIMT group, while both serum levels of Cyst-c and UA were lower in thickened cIMT group than those in plague formation group but higher than those in normal cIMT group (P<0.05). In addition, serum level of Hcy in normal cIMT group was higher than that in thickened cIMT group and plague formation group. The cIMT grade was positively correlated with serum levels of Hcy, Cyst-C and UA (r=0.26, 0.30, 0.23, P<0.05), but was negative correlated with HDL-c(r=-0.38, P<0.05). Further more, Logistic regression analy?sis showed that Hcy,Cyst-C and UA were independent risk factors for cIMT. Conclusion Serum levels of Hcy, Cyst-C and UA are closely related to the cIMT,which indicates that they are independent risk factors of cIMT and may be used as mark?ers in judging the developments and preventions of arteriosclerosis.

Nasopharyngeal carcinoma (NPC), a common head and neck neoplasm in southern China,is mostly treated with radiotherapy, however, it can not be completely cured by chemoradiotherapy. Recent investigation on NPC suggests that the nasopharyngeal carcinoma stem cells can be differentiated to heterogeneous cancer cells that have a strong ability for self renovation and further contribute to the development and progression of tumor itself which is closely related to drug resistance, recurrence and metastasis of NPC. Wnt/β-catenin, Notch, Hedgehog, NF-κB and mTOR signaling pathways play important roles in cancer stem cells. Study on nasopharyngeal carcinoma stem cells targeted therapies and its related pathways provides a new strategy for the clinical treatment of NPC.

Objective:To evaluate the effectiveness and safety of butyl phthalide capsules combined with Xueshuantong injection in the treatment of acute cerebral infarction (ACI). Methods: Cochrane Library, Medline, Embase, SCI, CBM, CNKI, VIP and Wanfang databases were searched from the building time to May 2016. The enrolled randomized controlled trails were studied by using Cochrane system evaluation methods to perform methodological quality assessment, and RevMan 5. 2 software was used to carry out Me-ta-analysis. Results:A total of 7 randomized controlled trails including 640 patients were enrolled. The results of Meta-analysis dem-onstrated that the effective rate of butylphthalide capsules combined with Xueshuantong injection was superior to that of Xueshuantong injection (RR=1. 33, 95%CI:1. 16-1. 52, P<0. 0001), butylphthalide (RR=1. 45, 95%CI:1. 15-1. 83, P=0. 002) and blank control (RR=1. 31, 95%CI:1. 08-1. 57, P=0. 005). NHISS of butylphthalide capsules combined with Xueshuantong injection was higher than that of Xueshuantong injection (MD=4. 63, 95%CI:3. 38-5. 87, P<0. 00001) and blank control (MD=6. 85, 95%CI:4. 90-8. 80, P<0. 00001). There was no significant difference in adverse drug reactions. Conclusion: Butylphthalide capsules combined with Xueshuantong injection is effective for the therapy of ACI. However, due to the limited quantity and quality of the in-cluded studies, larger scale trials are needed.

The intracellular trafficking and subcellular distribution of exogenous gene is very important for gene delivery. A successful gene vehicle should overcome various barriers including endosomal membrane barriers to delivery gene to the target organelle. Traditional nonviral vehicle is unable to avoid endosomal pathway efficiently, so the efficiency of gene delivery is low and the application of gene drugs is limited. In order to achieve efficient nonviral gene delivery, a lot of researches based on endosomal escape have been carried out and some agents with the function of endsomal escape have been found. These agents facilitate the endsomal escape via various mechanisms, such as fusion into the lipid bilayer of endosomes, pore formation in the endosomal membrane, proton sponge effect and photochemical methods to rupture the endosomal membrane. In this review, various reported strategies for endsomal escape are described according to the escape mechanisms, and their applications in intracellular gene delivery are also discussed.
