Objective: To investigate the diagnostic value of automatic breast volume system (ABVS) for breast carcinoma in clinical practice so as to use these reliable data to provide imaging reference for further therapy. Methods: 300 patients with suspected breast cancer were selected and the postoperative pathological examinations were chosen as the golden standard to implement screening. At the same time, 2 radiologists were selected to carry out the grading diagnoses of breast imaging reporting and data system (BI-RADS) so as to observe the consistency between diagnoses of ABVS and pathological results. Results: 210 patients were diagnosed as breast tumor by the post-operative pathological examination, and these patients included 89 malignant tumor (29.67%, 89/300). In these malignant cases, there were 42 cases were infiltrative ductal carcinoma, and its rate was 47.19% (42/89). Besides, there were 121 cases were benign tumor (40.33%), and the rate of patients with fibrosum adenoma (78 cases) was the highest in the 121 cases (64.46%, 78/121). And the diagnostic consistency of them was preferably (K=0.724). The sensitivity and specificity of ABVS in diagnosing breast carcinoma were 92.86% and 85.56%, respectively. Its positive predictive value and negative predictive value were 93.75% and 83.70%, respectively. And the Youden index was 0.78. Conclusion: ABVS has relatively high sensitivity and specificity, and the screening test has good authenticity and reproducibility. Therefore, it can provide a reliable basis for clinical diagnosis and treatment.

Raman spectroscopy is an optical technology based on the theory of Raman scattering, which is generally used in the research of medical and biological science. Raman spectroscopy can be used to detect the molecular structures and components of proteins, lipids, DNA, and other biological molecules, and provide substantial information about molecules. Thus, Raman spectroscopy is generally considered a "molecular fingerprint", and it has exceptional advantages in medical research. Moreover, this technique can reflect the changes in molecular structures and detect the alterations of chemical constituents in the samples. Raman spectroscopy, given its high sensitivity and specificity in the detection of the biological samples, has been successfully used to detect and diagnose diseases in numerous sites, such as skin, oral mucosa, breast, head, and neck. In this paper, we introduce the application of Raman spectroscopy in stomatology by conducting a review of the literature.

Objective The double-cavity balloon oppressor surgery for rhegmatogenous retinal detachment (RRD) has been utilized in past decades. But we have not yet a domestic device available. Present study was to investigate the effectiveness of double-cavity balloon oppressor using a domestic device in primary RRD surgery. Methods This clinical trial was a prospective study. Total 74 cases of patients with rhegmatogenous retinal detachment(RRD) (74 eyes) were enrolled. Double-cavity balloon oppressor surgery was performed in 40 eyes of 40 patients, and conventional segmental scleral buckling surgery was used in 34 eyes of 34 patients. The mean operative time, retinal attachment rate, vision and astigmatism change after operation between two different operative fashions were compared. The intra- and post-operative complication was discussed. The mean follow-up period was 4. 5 months. Written informed consent was obtained from all the patients before clinical trial. Results The retinal anatomic attachment rate was 92. 5% (37/40) in balloon oppressor surgery group and 91. 1% (31/34) in conventional surgery group, and there were no significant difference in retinal attachment rate among PVR grade A, B and C1 (P ＞0. 05) . The postoperative best corrected visual acuity (operative 3 months) was improved in 29 eyes(72. 5%) after balloon oppressor surgery and 25 eyes(73. 5%) after conventional surgery, showing insignificant difference between them (P ＞ 0. 05) . The mean surgical time was about (27. 00 ±8. 60) minutes in balloon oppressor surgery group and (47. 00 ± 14. 30) minutes in conventional surgery group(t =7. 41, P ＜0. 01) . Cylinder diopter change after surgery was insignificantly different between before and after operation in balloon oppressor surgery group (0. 52 ± 0. 30 D vs 0. 81 ± 0. 41 D, P ＞ 0. 05), however, there was a significant difference in cylinder diopter change between preoperation and postoperation (0. 65 ± 0. 32 D vs 1. 83 ± 0. 69 D, P ＜ 0. 05) . Conclusion Double-cavity balloon oppressor surgery for RRD is accurate and reliable. This operation procedure offer an economic, efficient and convenient choice for treatment of RRD.

The function of metabotropic glutamate receptor(mGluRs) in stress response was increasingly gaining recognition. The mGluRs can regulate the level of glucocorticoid(GC), the neurotoxin of glutamate and synaptic plasticity (LTP,LTD). So it may play an important role in stress response. The function of distinct type of mGluRs is different. Their mechanisms in stress response are very complex. So it is very essential to study the function of mGluRs in stress. Furthermore we can explore a new type drug targeting at mGluRs to cure the stress damage.-

Objective To understand the cognition of ICU syndrome by ICU nurses in Guangdong province. Methods Through questionnaire filling in, this investigation was made on the first hatch of ICU nurses dispatched to Hung Kong for ICU specialized training by Guangdong province. Information collected included the nurses' personal information and their knowledge about ICU syndrome. Results The sub-jects' knowledge about ICU syndrome was scanty, and was not related to their years of work, professional ti-tles, academic degrees or administrative duties. The overwhelming majority of the subjects had not paid at-tention to the disease in clinical work. Most departments had not formulated guidelines whatsoever on nurs-ing for ICU syndrome. In assessing the ICU syndrome, the vast majority of nurses relied on their clinical experience, with none of them relying on the confusion assessment method for the intensive care unit (CAM-ICU). Only very few of the subjects acquired some knowledge about the syndrome during their study at colleges. Conclusions The ICU nurses in Guangdong province should attach importance to ICU syn-drome and strengthen the study of related knowledge in their work and study. And it is essential to popular-ize CAM- ICU and to build a standard assessment system and work out the intervention measures for ICU syndrome.

Objective To assess the efficacy of the laryngeal mask airway i-gel (LMA i-gel) in patients undergoing neuro-interventional surgery. Methods Forty ASA Ⅰ or Ⅱ patients of both sexes, aged 20-60 yr,body mass index ＜ 30 kg/m2, undergoing elective neuro-interventional surgery, were randomized into 2 groups (n = 20 each):LMA i-gel group (group I) and LMA ProSeal group (group P). After induction of anesthesia with TCI of propofol and remifentanil, LMA i-gel and LMA ProSeal were inserted in group I and P respectively. The patients were mechanically ventilated and PETCO2 was maintented at 35-40 mm Hg,SpO2 at 99%-100%. BP and HR were monitored and recorded before induction, immediately after induction, at 1, 3 and 5 min after insertion of LMA and immediately after removal of LMA. The success rate, LMA placement time, leak pressure, peak airway pressure and complications were recorded. Results There was no significant difference in the success rate, the LMA platcement time and peak airway pressure between the two groups (P ＞ 0.05). BP and HR were within the normal range during operation in both groups. The leak pressure and incidence of blood stain and sore throat were significantly lower in group I than in group P (P ＜ 0.05). Conclusion LMA i-gel can provide adequate ventilation during operation with less complications and can be used effectively for neuro-interventional surgery.

Currently,the worldwide frequency of catastrophic e-vents has made post-traumatic stress disorder (PTSD)a major public health problem.As a stress-related psychiatric disorder, PTSD is considered as the result of interaction between gene and environments (especially early life adversity).The epigenetics plays an important role in PTSD pathogenesis.Due to the core role of hypothalamic-pituitary-adrenal (HPA)axis,the research on the relationship between HPA axis epigenetics and PTSD pathogenesis in recent years was reviewed in the paper so as to provide references and thinking of the prevention and therapy for PTSD in the future.

Atherosclerosis is the important pathologic basis of coronary artery disease,cerebrovascular disease,peripheral arterial disease and other vascular diseases.Studies have shown that the atheromatous plaques occur mainly in regions of curvature,bifurcation,and branching of the artery,indicating that low flow shear stress is closely associated with the occurrence of atherosclerosis.Low flow shear stress involves in the induction of atherosclerosis through acting on mechanosensitive molecules in endothelial cell that transduce mechanical stimuli into chemical signals,activate the corresponding intracellular signaling pathways.This article reviews the relationship between low flow shear stress and atherosclerosis.
