The patients' medication compliance was compared before and after intervention and their control of blood pressure was also observed. Results The difference was statistically significant in the comparison of patients' knowledge of antihypertension and the proper use of antihypertensive drugs before and after intervention. Blood pressure control rate was 80.82%.Conclusions Community nursing intervention can improve patients' medication compliance and effectively control the blood pressure of the patients.

The mechanisms of general anesthesia, which was introduced about 170 years ago, remain poorly under- stood. Even less well understood are the effects of general anesthesia on the human body. Recently we identified 18 G-protein coupled receptor (GPCR) genes of Daphnia pulex, an invertebrate model organism. Phylogenetic analysis identified these genes to be the homologs of the human γ-aminobutyric acid, type B (GABAB) receptor, metabotropic glutamate receptors (mGluR), adrenergic receptor, serotonin (5-HT) receptor, dopamine receptor and muscarinic acetylcholine receptor (mAChR). Using reverse transcription and quantitative PCR techniques, we systematically measured the effects of propofol, etomidate and ethanol on these 18 GPCR mRNA expressions in Daphnia pulex.

Objective To discuss the effects of applying electric heating pattern instrument in experimental teaching of fixed partial denture technology.Methods Totally 98 prosthodontic undergraduates of 2008 and 2009 grades were selected in this study； 46 students of 2008 grade were taken as control group and 52 students of 2009 grade were taken as experimental group.Students in experimental group made wax patterns with electric heating pattern instruments to melt inlay wax while those in control group made wax patterns with instruments heated by alcohol lamps.Teaching effects were evaluated by experimental test scores and questionnaires.Results Test scores of experimental group were (22.6± 1.8),obviously higher than those of (22.6-± 1.8) in control group (P ＜ 0.05).Satisfaction degree of experimental group were increased significantly compared with that of control group based on the resuits of questionnaire.Conclusions Applying electric heating pattern instrument in making wax patterns in experimental teaching of fixed partial denture technology is easy to operate and can improve the quality of wax pattern and working efficiency as well as enhance students' confidence,therefore it is worthy further spreading.

Objective To compare the humoral immune response of BALB/c mice immunized by recombinant plasmids PeDNA3.1-M-NS1 and pcDNA3.1-N-NS1.Methods Dengue type 2 virus(DENV2)NS1 gene were constructed two partial sequences(1-413 bp)of the pcDNA3.1 eukaryotic plasmids and pET28a(+)plasmid for prokaryotic expression,identification,purification and quantification.The BALB/c mice were immunized by pcDNA3.1-M-NS1,pcDNA3.1-N-NS1 recombinant plasmids with adjuvant.Each animal received a primary inoculation and two boosts at 1-week intervals.Then the blood samples of BALB/c mice were collected from different experiment groups at day 7,14,28 and 56,respectively after first immunization.The specific IgM/IgG antibodies for NS1 protein in serum were confirmed by indirect ELISA.And then the activities of the specific protective antibody were determined by cytopathic effect inhibition(CPEI).Results Construction of the pET28a(+)-NS1 m/pET28a(+)-NS1n prokaryotic expression plasmid,SDS-PAGE analysis showed that,NS1 gene partial sequence was expressed,both the relative molecular weight of about 22.3×103:Western blot showed that the protein can bind anti-His tag monoclonal antibody;byNi affinity chromatographywith apurity of 92% protein,on the C6/36 cell toxicity,and can be used ELASA detection.The results showed that the levels of specific IgM/IgG antibody and neutralizing antibody activities were increased in pcDNA3.1-M-NS1 booster immunization group than other groups.The result had been observed longer duration of antibody level in peDNA3.1-M-NS1 booster immunization group.Conclusion Humoral immune response were significantly different between pcDNA3.1-M-NS1 and pcDNA3.1-N-NS1 recombinant plasmid immunized mice groups.

BACKGROUND:The elastic modulus of the fiber post is close to that of the dentine, so they can form a homogeneous whole and share the masticatory force, which can ease the stress concentration of dentine and prevent from tooth fracture. OBJECTIVE:To observe clinical effects of anterior teeth with flared root canals restored by fiber posts using three application methods. METHODS:Anterior teeth with flared root canals from 48 patients were involved. They were divided into three groups, then restored with three post-core crowns respectively: a single fiber post, rehabilitation with composite resin, and fiber post combined with accessory post. Al patients were folowed up for 2 years to observe post and core loosening, fracture and root fracture. RESULTS AND CONCLUSION:The group of a single fiber post was failed in eight teeth including four cases of post and core loosening and four cases of post and core fracture, with a successful rate of 64%. The group of rehabilitation with composite resin was failed in three teeth including two cases of post and core loosening and one case of post and core fracture, with a successful rate of 90%. The group of fiber post combined with accessory post was failed in two teeth of post and core loosening, with a successful rate of 93%. The successful rate of the group of a single fiber post was lower than that of the groups of rehabilitation with composite resin and fiber post combined with accessory post (P < 0.05) . The difference between the groups of rehabilitation with composite resin and fiber post combined with accessory post was not statisticaly significant (P > 0.05). The clinical effects of rehabilitation with composite resin and fiber post combined with accessory post are better than that of a single fiber post. But the method of combination fiber post with accessory post is recommended because of easy operation.

Purpose To explore the expression of Toll-like receptor 4 (TLR4), PI3K, AKT and NF-κB in cervical lesions, and to in-vestigate their association with human papillomavirus ( HPV) 16 infection. Methods Immunohistochemical SP staining was performed to detect the expression of TLR4, PI3K, AKT, NF-κB in paraffin-embedded cervical tissue specimens from Uighur women with chroni-cal cervicitis, cervical intraepithelial neoplasia ( CIN) and cervical squamous cell carcinoma ( CSCC) . The HPV 16 DNA was detected by PCR. Results The positive expression rates of TLR4, PI3K, AKT, NF-κB in chronical cervicitis, CIN and cervical cancer were 32. 0%, 59. 4%, 77. 8%, 28. 0%, 56. 3%, 73. 0%, 24. 0%, 56. 3%, 79. 4%, and 8. 0%, 48. 4%, 81. 0%, respectively. The expression of them was higher in cervicitis than in CIN and cevical cancer ( P<0. 05 ) . The positive expression rates of HPV 16 in three groups were 8. 0%, 48. 4% and 81. 0% (P<0. 05). The expression of TLR4, PI3K, NF-κB and HPV 16 was related to cervi-cal cancer differentiation (P<0. 05). PI3K and AKT were significantly correlated with FIGOs’ stages (P<0. 05). NF-κB was corre-lated with lymph node metastasis. The expression of TLR4 was significantly associated with HPV 16 infection in CIN and CSCC ( r=0. 303, P=0. 015, r=0. 633, P=0. 000), and correlation with PI3K in CIN and CSCC (r=0. 254, P=0. 045, r=0. 386, P=0. 003). PI3K was associated with AKT only in CSCC (r=0. 298, P=0. 018). Conclusions The expression of TLR4 can be up-regulated by HPV 16 infection. High expression of PI3K/AKT signal pathway mediated by TLR4 may play important roles in the devel-opment and progression of CIN and CSCC, and HPV 16 infection may be a trigger factor affecting the molecular signal pathway.

The activity of plasma prolidase(PLD)was determined in patients with various chronic liver diseases.It was found that the activity of plasma PLD was increased significantly in 45 patients with cirrhosis and 31 patients with chronic active hepatitis.The plasma level of PLD was not correlated with the serum level of ALP.Plasma PLD was negatively correlated with serum albumin and positively correlated with serum gammablobulin.These findings suggest that the determination of the activity of plasma prolidase may be helpful in the diagnosis of chronic liver diseases.

VE: Chitosan and sodium tripolyphosphate were used as Complex matrix material for preparing pellets loading sodium diclofenac and its properties were studied. METHODS Chitosantripolyphosphate sodium polyelectrolyte was prepared according to the principle of static electricity polymerization. Its properties and structure characteristics were further investigated. The preparation process, effective factors and the optimal condition for the pellets loading sodium diclofenac were studied. RESULTS IR indicated that the structure of compound contained -NH3+-O-P group. DTA demonstrated that polyelectrolyte had an exothermic peak. There was no interaction between the drug and expedient. SEM showed that the surface of the pellets was regular, dense and the structure of the surface wasn't consistent with the inner. The pellets prepared by this method were uniform, round, well-distributed, hardy, good-mobility and its average diameter was about 10mm. CONCLUSION Chitosan-tripolyphosphate sodium polyelectrolyte could be used as a good matrix material for preparing pellets.

BACKGROUND:The elastic modulus of the fiber post is close to that of the dentine, so it can form a homogeneous whole and share the masticatory force, which can ease the stress concentration of dentine and prevent from tooth fracture. ＜br> OBJECTIVE:To investigate the effect of alveolar bone height and fiber post length on the fracture resistance of endodontical y treated maxil ary central incisors. ＜br> METHODS:Forty-eight human maxil ary central incisors were assigned randomly to six groups (n=8) of three different post insertion depths (5, 7, 9 mm) and two alveolar bone levels (2 and 5 mm) from the cement-enamel junction. Al of them were restored by glass fiber posts with composite resin core and cast metal crown. The samples were loaded in a testing machine with a crosshead speed of 1 mm/min at a 45° angle to the long axis of the tooth on the palatal surfaces until tooth fracture occurred. The maximum load and failure mode were recorded. ＜br> RESULTS AND CONCLUSION:Alveolar bone height had a significant influence on the fracture resistance (F=560.943, P>0.05), but fiber post length did not have a significant influence on it (P>0.05). Significant differences were found between the normal and resorbed alveolar bone groups in the number of repairable fracture patterns (χ2=5.689, P＜0.05). Under the circumstance of lowered alveolar bone height, lengthening fiber post cannot enhance fracture resistance of the teeth.

Intrathecal (I. T.)administration of K opioid dynorphin A (1-17) is used as a model of neurological dysfunction which lnvolved in spinal cord injury and secondary affection according to several previous reports. 5-amlno-2-phosphoveroleric acid (APV ), an NMDA receptor antagonist, can significantlly prevent the hindlimb paralysis in rats produced by I. T. dynorPhin A (1-17). To further investigate the mechanisms, we establis11 a nlodel of [3H]L,-Glu release in rats spinal slices influenced by dynorphin A (dynA ) (1-17). [3H]L-Glu release evoked by high [K+] (5Ommol/L,)is a Ca2+-dependent process. DynA (1-17) slgnificantly inhibited [3H]L,-Glu release at 1O-8mol/L,, but very significantly enhanced [3H]L-Glu release at 10-6 mol /L. The synthetic k agonist U50, 488H, which has no neurotoxic effect, inhibited [3H]L-Glu release at both high and low concentrations and did not have any enhancing effect. The results suggest that the analgesic effect of dynA (1-17) at physiological dosage may be rnediated by presynaptic K opioid receptor through the inhibition of Ca2+ influx and L-Glu release;but dynA (1-l7)enhanced L-Glu release through a non-opioid pathway and induced hindlimb paralysis at high neurotoxic dosage.
