Objective To investigate the expression and prognostic role of ADP-ribosylation factor 6 (ARF6) in human endometrial carcinoma.Methods 51 endometrial carcinoma tissues and matched tumor-adjacent tissues were collected from Jan.2010 to Dec.2011 in People's Hospital of Linzi District of Zibo City and Penglai People's Hospital.mRNA expression of ARF6 was detected by qRT-PCR,and the protein expression of ARF6 was detected by immunohistochemistry.The correlation between ARF6 and clinicopathological features was analyzed by chi-square test,and the Kaplan-Meier survival curves were drawn to describe the prognostic effects of ARF6 expression.Results Both mRNA and protein expression of ARF6 were down-regulated in endometrial carcinoma tissues than those in matched tumor-adjacent tissues (P＜0.05).Positive expression of ARF6 was associated with lynphatic metastasis (P＜0.05) and advanced TNM stage (Ⅲ+Ⅴ,P＜0.05).Both the 3-year overall survival rate and disease-free survival rate were lower in ARF6 positive expression group than in ARF6 negative expression group(P＜0.05).Conclusion Positive expression of ARF6 in human endometrial carcinoma is related to the malignant clinicopathological features and poor prognosis.

Objective To investigate the effects of penehyclidine hydrochloride (PHCD) pretreatment on expression of NF-κB and iNOS in rats with LPS-induced brain injury. Methods One hundred and five male SD rats weighing 200-220 g were randomly divided into 5 groups (n=21 each): group Ⅰ normal saline (NS);group Ⅱ LPS (L);group Ⅲ,Ⅳ,Ⅴ PHCD 0.05, 0.15, 0.45 mg/kg (D1,2,3). The animals were anesthetized with chloral hydrate 350 mg/kg. Brain injury was induced by intra-arterial LPS 150 μg administered via left internal carotid artery in group Ⅱ-Ⅴ. In group Ⅲ,Ⅳ, and Ⅴ PHCD 0.05, 0.15 and 0.45 mg/kg were given intraperitoneally (IP) at 10 min before intra-arterial LPS. The animals were decapitated at 4, 6 and 12 h after administration of PHCD (n=7 at each time point in each group). The brains were immediately removed for determination of water content, expression of NF-κB and iNOS protein and examination with light and electron microscope. Results Water content of the brain and expression of NF-κB and iNOS protein were significantly higher in group L, D1, D2 and D3 than in group NS and were significantly lower in group D2 and D3 than in group L. Intra-arterial LPS produced severe damage to the brain which was significantly attenuated by PHCD in group D2 and D3. Conclusion PHCD 0.15,0.45 mg/kg pretreatment can attenuate LPS-induced brain injury by inhibiting the up-regulation of expression of NF-κB and iNOS.

Objective To study the diagnostic value of single fiber electromyography (SFEMG) in diabetic peripheral neuropathy (DPN).Methods The values of jitter and fiber density (FD) in 36 patients with diabetes mellitus of 2 type were determined by Viking Ⅳ, while conventional nerve conduction studies (NCS) were performed,and the fasting blood glucose and glycosylated hemoglobin A 1C (HbA 1C ) were measured.Results The values of jitter were associated with FD, and both jitter and FD were positively related to HbA 1C .18 cases with abnormal NCS showed increased jitter(11 cases with block),and increased FD in 14 cases; the remaining 18 cases with normal NCS,7 cases with increased jitter(3 cases with block),the increased FD in 5 cases.Conclusion Denervation reinnervation reflected by jitter and FD was associated with the metabolic status. SFEMG could be served as sensitive means to early diagnosis of DPN, and might detect subclinical peripheral neuropathy of diabetes.

Objective To investigate the diagnostic value of F wave in diabetic peripheral neuropathy (DPN).Methods F and M wave parameters were measured in 106 patients with diabetes mellitus and 75 normal persons, including the minimum latency, duration, amplitude and area of F wave, and the amplitude and the area of M wave.Results (1) In the 30 patients with diabetes mellitus without peripheral neuropathy, there were 8 cases with prolonged the duration of F wave, 4 cases with prolonged the minimum latency of F wave, 2 cases with increased in the ratio of the area of F/M wave. (2) The minimum latency prolonged of F wave, the ratio of the amplitude of F/M wave and the ratio of the area of F/M wave significantly increased in the 76 patients with DPN, the duration of F wave prolonged in the mild DPN but no one revealed remarkable abnormal. (3) In the controls, the function of upper limit of the minimum latency of F wave (Y) and leg length (X) was Y=12.3+48.8X 2. Conclusion (1) F wave could be served as sensitive index to the early diagnosis of DPN, and might detect subclinical DPN. (2) The proximal nerve segment could be affected without the lesions of the distal nerve segment in patients with DPN, and it suggested that vascular factor plays an important role in the mechanism of DPN.

The purpose of this study was to investigate the effect of four kinds of different contact strength on the three-dimensional displacement of an implant-supported fixed bridge using digital laser speckle photography method. An in vitro model of beagle mandible with an implant-supported fixed bridge in its right premolar region was developed. The bridge was Au-Pt metal-ceramic. The contact was recovered to four different tightnesses, named 0, 1, 2, and 3. Different axial concentrated static load was applied to abutments and bridge respectively. The three-dimensional displacement of the implant-supported fixed bridge was measured using digital laser speckle photographic method. The results demonstrated that the influence of contact tightness was mainly on the mesio-distal and buccal lingual parts. When the contact tightness reached number 3, the regularity of displacement distribution was changed. The present study proved that digital laser speckle photography was an effective method of measuring the micro-displacement. One of the criterions of contact recovering decreased the implant displacement effectively without changing the regularity of displacement distribution.

OBJECTIVEThis work lays the foundation for establishing a digital model database with normal occlusion. A digital dental cast is acquired through grating projection, and model features are measured through reverse engineering.

METHODSThe grating projection system controlled by a computer was projected onto the surface of a normal dental model. Three-dimensional contour data were obtained through multi-angle shooting. A three-dimensional model was constructed, and the model features were analyzed by using reverse engineering. The digital model was compared with the plaster model to determine the accuracy of the measurement system.

RESULTSThe structure of three-dimensional reconstruction model was clear. The digital models of two measurements exhibited no significant difference (P > 0.05). When digital and plaster models were measured, we found that the crown length and arch width were not statistically different (P > 0.05), whereas the difference between the crown width and arch length was statistically significant (P < 0.05).

CONCLUSIONThe reconstruction of a digital model by using the grating projection technique and reverse engineering can be used for dental model measurement in clinic al and scientific research and can provide a scientific method for establishing a digital model database with normal occlusion.

Objective To study the antidepressant-like effect of Butanol Extract from Stevia (BEFS) and its possible corresponding mechanisms.Methods Forty-five mice were randomly divided into control group,model group,model + Fluoxetine group,model + BEFS-3 g/kg group and model + BEFS-6 g/kg group.The chronic unpredictable mild stress(CUMS) for 3 weeks was used to make up depressive animal model.It was based on body weight,crossing numbers,rearing numbers and sucrose preference to assess whether the model was a success.After continuous lavage giving BEFS and fluoxetine for 2 weeks and subsequent behavioral test,the mRNA transcription of Single immunoglobulin interleukin-1 receptor-related molecule (SIGIRR) and nuclear factor kappa-B (NF-κB) in liver tissue of mice were detected by using quantitative real time-PCR.Results Three weeks after CUMS,behavior parameters were significantly decreased in mice exposed to CUMS compared with control group[(17.28 ±0.49) g vs (22.47 ± 0.82) g,P =0.000;(43.35 ± 1.68) scores vs (125.25 ± 3.07) scores,P =0.000;(3.92 ± 0.18) scores vs (15.92 ± 1.78) scores,P =0.000;(49.39 ± 2.05) ％ vs (67.18 ± 4.46) ％,P =0.001].However,2 weeks after dosing,body weight,crossing numbers,rearing numbers and sucrose preference were (19.03 ± 0.44) g,(70.50 ± 6.56) scores,(3.08 ± 0.77) scores and (41.27 ± 7.59) ％,respectively in model group.Compared to model group,behavior parameters of BEFS (3 and 6 g/kg BEFS) groups were significantly increased [BEFS-6 g/kg group:(24.42 ± 1.46) g,(99.75 ± 5.07) scores,(13.08 ± 1.60) scores,(64.31 ± 1.92) ％,all P ＜ 0.05;BEFS-3 g/kg group:(23.82 ± 1.72) g,(91.67 ± 5.69) scores,(6.92 ± 1.05) scores,(59.56 ± 5.31) ％,respectively,all P ＜ 0.05].Correspondingly,BEFS could reverse the mRNA expression of SIGIRR lowering and NF-κB rising in the liver of mice exposed to CUMS(BEFS-6 g/kg group:1.208 1 ± 0.102 2,1.437 7 ± 0.352 9;BEFS-3 g/kg group:0.768 0 ± 0.108 6,2.186 2 ± 0.203 8,all P ＜ 0.05).Conclusions BEFS can remarkably improve depression-like behaviors in CUMS mice and its antidepressant activity is mediated,at least in part,by upregulating SIGIRR and downregulating NF-κB in the liver.

Objective To investigate the level about illness perception in patients with coronary heart disease. Methods From July to De-cember, 2015, 198 inpatients with coronary heart disease who were admitted into hospitals twice or more were enrolled. They were assessed with Illness Perception Questionnaire-Revised (IPQ-R). Results The score of common symptoms was (4.55±1.64). The symptoms, for exam-ple, chest pains, uncomfortable feeling in chest, cold sweat, flustered and breathlessness were most frequently experienced and most often identified. For the illness perception part, the scores on subscales of treatment control and consequences were higher than 3, which was the neutral point. For the cause dimension part, the highest scores was (3.38 ± 0.90) in diet or eating habits, followed by (3.38 ± 0.89) in aging. Among these factors, immune factors had the highest mean score, followed by stress factor. Conclusion The level of illness perception in pa-tients with coronary heart disease was in the middle level, and individual differences were obvious. The awareness of the disease and the in-tervention of the patient should be strengthened.

Objective To evaluate the post-puncture complications in children,and to evaluate the difference in the occurrence rate of headache and backache between patients who had 1 hour of supine recumbency and those who had 4 hours of supine recumbency,to provide evidence for the standardized lumbar puncture (LP) procedure of children.Methods Inpatients who were older than 3 and had diagnostic LP in the course of their treatment between Nov.2012 and Apr.2013 were enrolled.The LP was performed by the same investigator under the standardized institutional guideline for LP and the information of number of LP attempts,duration of LP and cerebrospinal fluid (CSF) drainage volume were recorded.After the procedure,all the children were randomly assigned into 2 groups:the test group had supine recumbency for 1 hour after LP,and the control group had it for 4 hours.For the first 5 days following LP,reports of headache and backache were recorded by another physician who didn't participate in this study.The difference in the occurrence rate of headache and backache between test group and control group was assessed by the chi-square test or Fisher's probabilities in 2 × 2 table.And a Logistic regression analysis was performed to assess the risk factors for the occurrence of the headache and backache.Results The overall frequency of headache was 4.6％ (4/87 cases).The frequency of headache was not significantly different between the test group (2.4％) and control group (6.7％) (P =0.617).And the overall frequency of backache was 19.5 ％ (17/87 cases),and it was not significantly different between the 2 groups (test group:21.4％,control group:17.8 ％,P =0.668).In a Logistic regression analysis,age (P =0.011,OR:6.884,95％ CI:1.398-33.906) and the previous history of lumbar puncture (P =0.018,0R:0.126,95 ％ CI:0.026-0.618) were significant risk factors for the occurrence of backache.The risk of backache in children with more than 2 times of LP was decreased.And the risk was higher in the children older than 6 years than those younger than 6 years.Conclusions Headache and backache were the most frequent post-puncture complications in children.There was no difference between short duration (1 hour) of supine recumbency and long duration (4 hours) in preventing the occurrence of headache and backache after LP.
