Making dental impressions and models is a part of daily routine work for dental nurses in the orthodontic department in China. This paper analyzes the common problems encountered in the process of making dental impressions and models, and emphasizes the importance of quality control and supervision during this process. A method of combining real-time monitoring and periodic inspection based on nurse-doctor cooperation was put forward to ensure the quality of dental impressions and models. Firstly, the nurses should be well trained with the instruction of doctors before on duty; Secondly, the head nurse should be responsible for implementing real-time monitoring and periodic inspections to find the problems and take measures in time. Also, the doctors should check the dental impressions and models in time, especially for those models with special demands, and help the nurses to improve their skills constantly.

Objective To investigate the pathogenesis of cerebral watershed infarction (CWI) through analyzing the appearance examined by Color duplex Imaging(CDI) and transcranial doppler (TCD).Methods One hundred and forty-two patients with CWI diagnosed by magnetic resonance imaging(MRI) were enrolled in the study group and 150 patients with acute cerebral infarction were enrolled in the control group.The results of CDI and TCD were retrospectively analyzed of the two groups.The vascular stenosis,plaque detection rate,plaque characteration,plaque scores,the cause of low blood volume,intracranial collateral circulation were compared between the two groups to investigate the pathogenesis of CWI.Results Among the 142 cases in the study group,there were 72 cases of severe stenosis and occlusion,21 cases of moderate stenosis,31 cases of mild stenosis and 18 cases without stenosis and there were 19 cases of severe stenosis and occlusion,41 cases of moderate stenosis,23 cases of mild stenosis and 67 cases without stenosis among the 150 cases in the control group.There were significant differences in the two groups (x2 =66.583,P =0.000).There were significant differences on the plaque detection rate between the two groups (80.99％ (115/142) vs 49.33％ (74/150),x2 =32.010,P =0.000).There were significant differences on the scores of plaque between the study group and the control group ((11.47 ± 3.78) points vs (6.57 ± 3.53) points,t =4.019,P =0.001).There were significant differences on the defined cause of low blood volume between the study group and the control group (54.93％ (78/142) vs 11.33％ (17/150),x2 =63.164,P =0.000).There were 50 patients had collateral circulation in the study group and 38 cases in the control group,there were no significant differences between the two groups (35.31％ (50/142) vs 25.33％ (38/150),x2 =3.381,P =0.066).Conclusion Angiostegnosis,microemboli from the unstable atherosclerosis plaque,lower perfusion on the basis of hypovolemia are all the pathogenesis of CWI.CDI combine with TCD can provide more information in vascular evaluation and treatment.

Objective To explore the relationship between the level of serum homocysteinaemia(Hcy) and the carotid artery atherosclerosis(CAA),and its change after intervention therapy with folate acid and VitaminB12 (VitB12). Methods The levels of serum Hcy,folate acid and VitB12 were measured in 169 patients with cerebral infarction(CI group) and 110 normal controls(NC group). The condition of carotid arteries was checked by color dopper flow image in CI group. The relationship between the level of serum Hcy and folate acid,VitB12 and CAA condition were analysed. The change of serum Hcy level was observed after intervention treatment of folate acid and VitB12 for 4 weeks in CI patients with hyperhomocysteinaemia.Results Compared with the NC group,the level of serum Hcy was significant higher in CI group(P

Objective To illustrate the evaluation effect of bivariate analysis of sensitivity and specificity meta-analysis model in diagnosis test to provide basis for selecting better evaluation method of diagnostic test.Methods Bivariate model was presented by reanalyzing the data from a published meta-analysis of two diagnostic techniques in diagnosis of schistosomiasis japonica.Results The bivariate model could directly provide summary estimates of(logit)sensitivity,specificity and DOR with corresponding 95% CI for two diagnostic tests(IHA and ELISA).Also,it could elicit any significant difference that existed among sensitivity,specificity and DOR between the two diagnostic methods,and incorporate any correlation that existed between sensitivity;specificity.Conclusion The bivariate model preserves the two dimensional nature of the original data,and separates effects of sensitivity and specificity,which is more rational than a net effect on diagnostic odds ratio scale as in SROC approach.The bivariate model is appropriate and agile,and can be used as an extension and improvement of the traditional SROC method.

Objective To explore the relationship between collateral circulation and clinical manifestation after se-vere stenosis or occlusion of internal carotid artery. Methods According to the clinical manifestation, 78 cases of ICA ste-nosis or occlusion confirmed by digital subtraction angiography (DSA) were divided into two groups:asymptomatic group (n=31) and symptomatic group (n=47). Collateral circulation pathway in circle of Willis and the mean flow velocity of the middle cerebral arteries (MVMCA) were measured by Transcranial Doppler Ultrasonography (TCD). The correlation of the types of intracranial collateral circulation and clinical manifestation was analyzed. Results ① The collateral circulation opening rate of severe stenosis or occlusion of internal carotid artery in 78 cases of patients was 70.5%(55/78). The collat-eral patency rate (27/31, 87.1% of patients) was higher in asymptomatic group than in the symptomatic group (28/47, 59.6%of patients)(P<0.01).②Collateral patency of anterior communicating artery (ACoA)in asymptomatic group (24/31, 77.4%of patients) was higher than that in symptomatic group (20/47, 42.6%of patients) (P<0.01). Collateral patency of ophthalmic artery (OA) in symptomatic group (21/47, 44.7%of patients) was higher than that in asymptomatic group(6/31, 19.4%of patients)(P<0.05). The opening rate of ACoA was significantly higher than that of either the posterior commu-nicating artery (PCoA) or OA collateral circulation in asymptomatic group (P<0.05).③The mean flow velocity of the af- fected side middle cerebral arteries (MVMCA) in asymptomatic group (51.58±12.36cm/s) was significantly higher than that in symptomatic group (32.23±10.31cm/s) (P<0.01). Conclusion The clinical manifestation is closely related to arterial circle of Willis collateral circulation opening after severe stenosis or occlusion of internal carotid artery and collateral patency of anterior communicating artery is the major collateral supply vessel.

Objective To investigate the inhibitive effects of treatment with new recombinant humantumor necrosis factor (nrhTNF) and/or etoposide (VP16) on murine lung cancer. Methods Tumor-bearingmice were randomly divided into four groups. NS, nrhTNF, VP16, nrhTNF and VP16, were respectivelyinjected into endoneoplasm in every group. Results Inhibition rate in nrhTNF group and VP16 group were33.71 % and 30. 46% respectively and resulted in tumor necrosis to a certain degree. The number of lungmetastatic tumors in the mentioned groups above were less than that in control group (P

Objective:To study the relationship of Guangxi Zhuang women being infected by HPV16 and suffering from cervical cancer with HLA-DQB1 allele polymorphism.Provide clues for seeking hereditary susceptibility gene or resistant gene of cervical cancer of Guangxi Zhuang women.Methods:Chose the cervical cancer diagnosed female patients and health women 171 cases respectively aged between 25 and 45 of Guangxi as subject investigated(people in the two groups were paired by age ±3 years).Took their samples to extract HPV DNA and human genome DNA.Then detected HLA-DQB1 alleles and HPV genetype applying PCR-SSP and molecular diversion hybrid technology.Finally the data were statistically analyzed.Results:(1)The total infection rate of HPV in 171 cases of cervical cancer patient was 91.22%,in which the high-risk virus accounted for 90.76%,HPV16 was the main pathogenic subtypes(43.58%).(2)The allele carrying rate of HLA-DQB1*04 in the cervical cancer group was higher than the health control group with statistically significant difference(P<0.05).The allele carrying rate of HLA-DQB1*06/09 in the cervical cancer group was lower than the health control group with statistically significant difference(P<0.05).There was no significant difference of the allele carrying rate of HLA-DQB1*02/05/07/08 between two groups(P>0.05).(3)The occurrence frequency of HLA-DQB1*04 alleles in HPV16 positive cervical cancer patients was significantly higher than HPV16 negative patients with statistically significant difference(P<0.05).Conclusion:HLA-DQB1*04 alleles are probably the susceptibility genes of cervical cancer of Guangxi Zhuang women;HLA-DQB1*06/09 alleles are probably the protective genes of cervical cancer of Guangxi zhuang women;HLA-DQB1*02/05/07/08 alleles seem irrelevant to hereditary susceptibility of cervical cancer of Guangxi Zhuang women.And Guangxi Zhuang women carried HLA-DQB1*04 alleles are more likely to infect HPV16 that increase the risk of cervical cancer.

Sirt3 is a kind of nicotinamide adenine dinucleotide (NAD+)-dependent deacetylases.Sirt3 is localized in mitochondria and has been involved in a wide range of mitochondrial biological functions, such as nutrient oxidation、ATP generation, reactive oxygen species (ROS) detoxification and mitochondrial homeostasis.Sirt3 plays an important role in the occurrence and development of cardiovascular diseases.Increased expression of Sirt3 gene has been associated with extended lifespan of humans.

Objective To evaluate the injury of optic radiation after ischemic stroke with diffusion tensor imaging (DTI). Methods From September, 2014 to September, 2015, twenty-one ischemic stroke inpatients with visual field defects were tested with DTI, and measured the fractional anisotropy (FA) and apparent diffusion coefficient (ADC) of both sides in different time. The correlation of FA and ADC to visual field mean defect (MD) in the same time was analyzed. Results The FA of affected sides was lower than that of healthy sides twenty-four hours (t=2.38, P<0.05), one week (t=15.60, P<0.01) and four weeks (t=19.13, P<0.01) after stroke, and the ADC was also lower twenty-four hours (t=10.13, P<0.01) and one week (t=6.06, P<0.01) after stroke. The FA correlated with MD one (r=0.581, P<0.01) and four weeks (r=0.703, P<0.01) after stroke, and the ADC correlated with MD twenty-four hours after stroke (r=0.519, P<0.05). The FA of one (r=0.525, P<0.05) and four weeks (r=0.762, P<0.01) after stroke correlated with MD six months after stroke. Conclusion DTI can be used to evaluate the injury of optic radiation after ischemic stroke.
