Aim To investigate influence of amitriptyline on glutamate-aspartate transporter(GLAST)in spinal cord of rats after spared nerve injury.Methods 60 male SD rats were randomly divided into 4 groups with 15 rats in each:control(A),SNI(B),amitriptyline(C),SNI+amitriptyline(D).Respectively 4 groups were treated with intraperitoneal injections of 0.2 ml saline(A and B),10 mg?kg-1 amitriptyline(C and D),bid.The L3～L6 segments of the spinal cord were isolated in 1,3 and 5 days after surgery.Expression of GLAST was determined by western blot and semiquantitative RT-PCR.Also,changes of mechanical withdrawal threshold(MWT)were measured.Results Compared to control,a markedly decreased MWT was showed in group B and the expression of GLAST at both protein and mRNA level increased firstly and decreased later.There were no changes of MWT in group C,but the expression of GLAST increased gradually.Rat MWT in group D did not change any more at the third days after surgery.In addition,the expression of GLAST in group D was higher than control group and kept stable.Conclusions Amitriptyline could increase the expression of GLAST,which may be one of its mechanisms in the treatment of neuropathic pain.

Objective To investigate influence of amitriptyline on astrocytic activation in spinal cord of rats after spared nerve injury(SNI).Methods A total of 120 male SD rats were randomly divided into 4 groups with 30 rats in each group:control(A),SNI(B),amitriptyline(C),and SNI+amitriptyline(D)groups,which respectively were treated with intraperitoneal injections of 0.2 ml normal saline(A and B),10 mg/kg amitriptyline(C and D),bid.The L3 to L6 segment of the spinal cord was isolated respectively at 1,3 and 5 d after surgery.Expression of glial fibrillary acidic protein(GFAP),marker of astrocytes,was determined by immunofluorescence,Western blot assay and semiquantitative RT-PCR.The changes of mechanical pain threshold were measured.Results Compared with control,group B had a markedly decreased rat mechanical pain threshold(P

Objective Accidental public health emergencies occurred frequently all over the world in the last decade. The problem of how to set up an effective system for prevention and control of infectious diseases has aroused the attention of all the nations worldwide. The present paper discussed the contributions of the clinical laboratory in hospital during public health emergencies by collecting samples, establishing and applying a rapid diagnosis platform for infectious pathogens, ensuring laboratory biosafety, and developing a strategy in case of emergency. These countermeasures may be helpful for the army to establish an effective system and mechanism in handling public health emergencies.

It has been demonstrated that the combination of abnomal expression of gastrin with its receptor can promote cell proliferation and inhibit apoptosis in colorectal neoplasms via signal transduction pathways,which is related with the abnormal expression of miRNA.Researches show that there are multiple intersections between the molecule mechanisms of miRNA and the signaling pathway of gastrin in promoting colorectal cancer cell proliferation.It may exist a gastrin-miRNA-target gene signaling transduction pathway.Knowing the mechanism of the signaling pathway and controlling the related factors will open another avenue for the gene targeted therapy of colorectal neoplasms.

Objective To observe the effect of moxibustion and ear acupoint pressing method in treating dry eye syndrome.Methods Will meet the inclusion criteria of 63 patients were randomly divided into a treatment group (n=31) , treated with moxibustion and ear acupoint pressing method, and a control group (n=32) who were given with sodium hyaluronate eye drops. After 4 weeks' treatment, clinic symptom,break-up time of tear film(BUT), fluorescence staining(FL) and tear meniscus height(TMH) were measured and compared respectively.Results After treatment, the BUT (8.28 ± 1.73 svs.5.00 ± 1.51 s,t=11.948) in the treatment group was longer than the control group (P<0.01), FL score (1.00 ± 0.90vs.1.85 ± 1.45,t=4.057) in the treatment group were lower than the control group; TMH(0.28 ± 0.06 mm vs.0.20 ± 0.06 mm,t=6.768) in the treatment group were higher than the control group (P<0.01). After treatment, dry sense (1.61 ± 0.67 vs.2.60 ± 0.89,t=6.053), foreign body(1.00 ± 0.45 vs.1.85 ± 1.45,t=10.460), burning(0. 39 ± 0.67 vs.1.59 ± 0.87, t=6.142), visual fatigue (0.61 ± 0.67 vs.1.50 ± 1.16,t=3.725), eye expansion (0.29 ± 0.46 vs.1.28 ± 1.02, t=4.980), Photophobia (0.77 ± 0.76 vs.1.67 ± 0.90,t=4.092), cry (0.29 ± 0.46 vs.0.59 ± 0.91,t=2.038) integral in the treatment group were lower than those in the control group (P<0.05,P<0.01).Conclusion The effect of moxibustion and ear acupoint pressing method in treating dry eye syndrome is more effective than sodium hyaluronate eye drops.

Oncolytic adenoviruses are genetically altered to replicate within tumor cella while exhibiting a high degree of infectivity,good safety and specificity.The use of oncolytic adenoviruses to treat malignant brain tumors has been proved to be a promising mode of cancer therapy.Local injection of adenoviral vectors fails to reach scattered infiltrative tumor cells within the brain parenchyma and the therapeutic effect of intracereberal injections of oncolytic adenoviruses is only seen in the vicinity of the injection site.To remedy this and prevent possible tumor recurrence,stem cells have been explored as vehicles for gene therapy in brain tumors given that they possess an intrinsic tropism for brain glioma.

Objective To understand the distribution of pathogen and antibiotic resistance of nosocomial fungal infection,and provide evidence for the prevention of fungal infection in premature infants in hospital.Methods The clinical data of 72 cases of premature infants with nosocomial fungal infections were retrospectively analyzed.Results The top three of the pathogenic of fungal infection in premature infants in our hospital were 38 strains of Candida pelliculosa (52.8％,38/72),10 strains of Candida albicans (13.9％,10/72),9 strains of Candida parapsilosis (12.5％,9/72).The weights of 72 cases with nosocomial fungal infection in preterm infants were below 2000 g,who were dominated by very low birth weight infants.Gestational age of 27 ～ 30 weeks were in the majority,which accounted for 36.1％ of 27 ～ 28 weeks (26/72) and 34.7％ of 29 ～30 weeks (25/72),each group were dominated by bacteria pathogen candida.Seventy-two strains of fungi were isolated to amphotericin B drug resistance,the 1.4％ (1/72) resistance rate to fluconazole,4.2％ (3/72) pairs of voriconazole resistance rate,2.8％ (2/72) for itraconazole resistant rate.There were no significant differences among the last three resistant rate (x2 =1.02,P ＞ 0.05).The 5-fluorine cytosine resistance accounted for 59.7％ (43/72),and the 4 kinds of drug resistance rate had significant difference (x2 =57.73,P ＜ 0.05).There was no significant difference in resistance rate between amphotericin B and fluconazole (x2 =1.01,P ＞ 0.05).Conclusion Fluconazole could be used to those premature infants with high risk factors of fungal infection.Once the fungal infection is diagnosed,intravenous fluconazole could be the first choice,when necessary,amphotericin B can be used together.

Oncolytic adenoviruses have been used in cancer gene therapy because of their ability to selectively transfect and repli-cate in tumor cells. However, systemically administering oncolytic adenoviruses is often inefficient because the host's immunity also at-tacks the viruses. Delivering oncolytic adenoviruses by loading them into mesenchymal stem cells effectively solves this problem. Mes-enchymal stem cells have been described to possess a tumor-homing ability, as well as the capacity to deliver oncolytic adenoviruses. This review discusses the current challenges faced by oncolytic adenovirus delivery via mesenchymal stem cells.
