Objective The purpose of this study was to evaluate the disinfection effectiveness and properties of acrylic resin via microwave irradiation. Methods Forty acrylic resin base dentures fabricated in a standardized procedure were chosen and divided into Group A,B,C and D randomly. Group A,B and C were immersed in 200ml distilled water and submitted to microwave irradiation at 700W for 3,4,5 minutes individually. Group D was used as positive control. Bacteria specimens from each group were got for culture and numbers were calculated. Then the four groups were tested for the flexural strength and impact strength by universal test machine before and after microwave irradiation sterilization. Results The germicidal ratio of Group B was more than 90% ,while the ratio of group C was 100%. There was no significant difference in flexural strength and impact strength between group C and group D. Conclusions Microwave irradiation for 5 minutes at 700W produced sterilization of dentures contaminated with all bacteria whereas the denture strength is not affected. Microwave irradiation at 700W solution for 5 minutes was effective to sterilize acrylic resin base dentures.

Objective To explore the pressure of hospitalized patients and protrudent problem of mental stress.Methods Choosing 150 non-psychiatric patients in random for investigation using mental status scale in non-psychiatric patients.At last, data were analyzed to find out the stressors they were bear-ing in hospital.Results There existed mental pressures in hospitalized patients in some degree."to ex-pect to recover health early" was the highest score (7.21±3.17), and "to worry about their position de-creased after disease" got the lowest score, (2.56±2.15).The mental stress of hospitalized patients was cor-related with age, sex, education degree, income and marital status.Conclusions There existed mental pressures in hospitalized patients in some degree.Different mental stressor shows different psychological re-action, we should take different measures to improve the life and nursing quality of hospitalized patients.

Objective To investigate the clinical value of multi-slice spiral CT (MSCT)in diagnosis of internal abdominal hernia (IAH).Methods The MSCT findings in 1 5 patients with IAH confirmed by surgery were retrospectively analyzed.Results MSCT showed intestinal obstruction in 14 patients with strangulating intestinal obstruction in 8.The typical features of MSCT were as follows:translocated position of intestines (occupying effect),closed loop intestinal obstruction (gathered intestinal loops with different forms),assembled,expanded and translocated blood vessels of mesenteries,and thickened intestinal walls with ischemic edema and abnormal density.Surgical results showed paraduodenal hernia in 2,transomental hernia in 2,transmesenteric hernia in 5,ankylenteron strap hernias in 4,pericecal hernia in 1 and hernia through the Douglas fossa in 1,Intestinal obstruction in 14 and strangulating intestinal obstruction in 8 were also confirmed by surgery.The CT findings of IAH were correlated with the surgical results,and the accurate rate of grading of intestinal obstruction with CT was also consistent with the surgical results (Kappa=0.758,t=3.462,P=0.001).Conclusion IAH can be diagnosed accurately by MSCT in most patients,MSCT is helpful for guiding the surgical programs.

Objective To investigate the effects of Modified Siwutang aqueous extract (mSWT) on bone marrow cell mobilization and plantation in mice after acute myocardial infarction (AMI).Methods The AMI model was established by ligating the left anterior descending artery in Kunming mice.Bone marrow cells were marked by injection of DAPI into the cavitas medullaris of shin bones.Mice were administered with mSWT 60 mg/kg by intragastric administration once a day after surgery.After haematoxylin-eosin and immunofluorescent staining,the plantation of bone marrow cells in AMI area and microvessel density were detected by histopathological assay.The EPCs proportion of peripheral blood was measured by flow cytometry.Results Compared with model mice,infarct size obviously was decreased after mSWT 60 mg/kg treatment,with EPCs ratio increased significantly.Inflammatory cell infiltration of myocardium was much less.Myocardium cellular degeneration and necrosis,fibrosis were reduced,which survival cardiac muscle tissue was increased.DAPI positive cells of plantation and survive were found in AMI region of mSWT group.The number of positive cells were increased in mSWT group than that of model group.There were lot of microvessels of vWF positive expresseion in mSWT than model group.Conclusion:mSWT significantly improved histopathology of AMI mice.The mechanism may be involved in moved bone marrow cells,homed to AMI area and promote angiogenesis.

Aim To investigate the effects of total gin-senosides ( TG) on microvascular regeneration and car-diac function in rat after acute myocardial infarction ( AMI ) . Methods The acute myocardial infarction model was created with left coronary artery ligated in male Sprague Dawley rats. The model rats were ran-domly divided into sham, model, TG low and high dose groups. TG groups were injected into abdominal cavity with TG(20 mg·kg-1·d-1, 40 mg·kg-1· d-1 ) . Sham and model groups were injected with e-qual-volume normal saline. On the 35th day post-opera-tion, heart function was examined by color doppler ul-trasoundination. HE, Masson and immunohistochemis-trical staining were used to observe the histopathologi-cal changes of myocardium and micro vessel density. The level of vascular endothelial growth factor( VEGF) and basic fibroblast growth factor( bFGF) mRNA were detected by real-time PCR. Results Compared with the model group, high and low dose TG obviously de-creased the left ventricular end diastolic dimension, the left ventricular end-systolic dimension, the left ventric-ular end-diastolic volume and the left ventricular end-systolic volume(P<0. 05 and P<0. 01), and signifi-cantly increased the ejection fraction and the fractional shortening ( P <0. 01 ) . The histopathological changes of myocardium on myocardial infarction and fibrosis were dramatically reduced by TG. But ventricular wall was thicker. Two dose TG remarkably increased the expressions of VEGF and bFGF mRNA and micro ves-sel density of compositive CD31 + cells in ischemic myocardial tissue and around of infarct area(P<0. 01, P <0 . 0 5 ) . Conclusions TG could improve the car-diac function of acute myocardial infarction rat. The mechanism may be related to the upregulation of VEGF and bFGF gene expression, the promotion angiogene-sis, then the improvement of blood supply in myocardi-al infarction area.

OBJECTIVE: Insertion of a foreign body in the nasal cavity is a very common incident in children. It is easily diagnosed, but the type of foreign body varies and the extraction can sometimes be difficult with risk of complications. The present study reported nasal foreign bodies diagnosed in emergency in our ENT department, with an update on the state of knowledge. METHOD: A prospective study between Feb 2013 to Sept 2015 included patients admitted to the ENT emergency unit for nasal foreign body. Data comprised age, gender, circumstances of discovery, symptoms, type of foreign body, extraction method and complications. Many patients required anterior rhinoscope for the diagnosis and removal (179/249, 71. 9%), and 170 cases were directly removed and 9 cases were into alimentary canal; Most irregularly shaped objects were removed by a endoscope under general anesthesia (70/249, 28.1%), including button batteries (n= 65), nasal calculi (n = 2) and chopsticks (n = 3). RESULT The main types of foreign body were vegetal forms (61.8%). The incident was discovered following nasal symptoms in 24.9% (n = 62). Extraction was easy by using forceps, micro-hooks or suction in 71.9% of qn:Nasal sinuses foreign body on prevention, detailed history and make the necessary inspection, can improve the correct diagnostic rate.

Patients in intensive care unit were more critically ill, and often accompanied by dottiness and restless. In order to avoid the adverse events and self-injury, body constraints were often used on the patients. Therefore, this paper would discuss the ethics of body constraints and give the suggestions. According to the literature review and the analysis of the clinical nursing experience of relevant ethical principles, data was collected. The principle of informed consent, respect, and harmless was hard to decide on the issue of body constraints for patients in ICU. Nurses might pay attention to the application of ethical principles, and strengthen the humanistic care. On the issue of body constraints for ICU patients, nurses might pay special attention to the application of possible ethics principles in nursing process and reduce the application of the body constraints, and promote the physical and mental comfort of patients. It reflected the progress of the humanistic solicitude in the current clinical nursing and important value.

Objective To explore the impact of berberine on serum levels of insulin resistance and cytokines in schizophrenia patients treated with risperidone. Methods Sixty-four schizophrenia patients treated with risperidone were randomized to berberine group (n=31) and control group (n=33). The fasting plasma blood glucose (FBG) and fasting insulin (Fins) were detected before and after treatment in two groups. The homeostasis model assessment for insulin resistance (HOMA-IR) was calculated. The serum levels of interleukin (IL)-1β, IL-6, tumor necrosis factor-alpha (TNF-α) were evaluated by enzyme linked immunosorbent assay before and after the treatment. Results Compared with control group and pre-treatment group, the levels of FBG, Fins, HOMA-IR, IL-1β, IL-6 and TNF-α were significantly decreased after treatment in berberine group (P<0.05). The FBG level was significantly higher, the levels of IL-1β, IL-6 and TNF-αwere significantly lower, after treatment in control group (P < 0.01). There were no significant changes in Fins and HOMA-IR after treatment (P > 0.05). There was positive correlation between HOMA-IR and IL-1β, IL-6 and TNF-α in berberine group (r=0.316, 0.351 and 0.401, P<0.01). Conclusion Berberine can significantly decrease FBG, Fins, HOMA-IR, IL-
1β, IL-6 and TNF-α levels in schizophrenia patients treated with risperidone. The HOMA-IR level is closely correlated with IL-1β, IL-6 and TNF-αlevels.

The epithelial cells of normal human epididymis were studied by ultrathin section and freeze-etching replica techniques. It was found that the pseudostratified epithelium is composed mainly of dark-columnar, clear-columnar, ciliated, basal and few narrow-columnar cells. The ultrastructure of the epithelia from the head region to the tail of the epdidymis reveals no distinctive segmental demarcation, but transits gradually. The ciliated cells distributed chiefly in the initial segment of epididymis, fibril-like elements were found frequently in the supranuclear region of its cytoplasm, yet their function remains unknown. The dark-columnar cells as well as the clearcolumnar and the cillated cells of the head region of the epididymis exhibit the cytological ultrastructural characteristic features of absorption as is often the case with endocytotic vesicles and lysosomes, etc. These morphologycal findings confirm the view that these cells, particularly the dark-columnar cell, appear to be responsible to the absorption of testicular secretion in the epididymis. The clear-columnar and the dark-columnar cells, especially the former, in the distal portion of the epididymis possesses the secretory cytological characterestics. It is suggested that these cells were concerned with the production of the epididymis semen.In the discussion, the authors pointed out that the scientific basis for the detailed functions of the epididymis remains to be investigated further.
