Abstract
We report a measurement of electron antineutrino oscillation from the Daya Bay Reactor Neutrino Experiment with nearly 4 million reactor ν[over ¯]_{e} inverse β decay candidates observed over 1958 days of data collection. The installation of a flash analog-to-digital converter readout system and a special calibration campaign using different source enclosures reduce uncertainties in the absolute energy calibration to less than 0.5% for visible energies larger than 2 MeV. The uncertainty in the cosmogenic ^{9}Li and ^{8}He background is reduced from 45% to 30% in the near detectors. A detailed investigation of the spent nuclear fuel history improves its uncertainty from 100% to 30%. Analysis of the relative ν[over ¯]_{e} rates and energy spectra among detectors yields sin^{2}2θ_{13}=0.0856±0.0029 and Δm_{32}^{2}=(2.471_{-0.070}^{+0.068})×10^{-3} eV^{2} assuming the normal hierarchy, and Δm_{32}^{2}=-(2.575_{-0.070}^{+0.068})×10^{-3} eV^{2} assuming the inverted hierarchy.

Abstract
Laryngeal cancer (LC) is one of the most common malignant tumors that occur in the head and neck. Emerging evidence shows that coding RNAs and non-coding RNAs play key roles in the formation and progression of LC. In this review, we focus on the regulation of lncRNAs in LC. LncRNAs appear to be involved in laryngeal cancer growth, invasion, and metastasis and in establishment of the laryngeal tumor microenvironment through various mechanisms. Furthermore, we also discuss the possibilities of establishing lncRNAs as potential biomarkers and therapeutic targets for laryngeal cancer. Taken together, we summarize the emerging roles of lncRNAs in laryngeal cancer development and their possible clinical significance.

Abstract
Objective: To analyze docetaxel (T) and carboplatin (C) combined with trastuzumab (H) -TCH regimen as neoadjuvant systemic therapy in early breast cancer patients with human epidermal growth factor receptor 2 (HER-2) positive. Methods: From January 2008 to December 2014, the data of patients diagnosed as early breast cancer in Breast Disease Center of Peking University First Hospital were retrospective reviewed. The data of patients with HER-2 positive conducted TCH neoadjuvant therapy and surgery, and with the complete clinicopathological information were analyzed. Results: A total of 77 cases were enrolled in this study. We defined G2+ G3+ G4+ G5 as responsive group according to Miller-Payne grading system, the responsive rate was 84.4% (65/77). The rate of complete pathological remission (pCR) was 39.0% (30/77). The 5-year disease free survival (DFS) was 87.3%, and 5-year overall survival (OS) was 93.6%. There was a significant difference between DFS and OS in the responsive group and non-responsive group (DFS: χ2=6.762, P=0.009; OS: χ2=5.062, P=0.024). Conclusion: TCH is an effective neoadjuvant therapy for patients with HER-2 positive breast cancer, and the toxic and side effects were under control.

Abstract
Objective: To investigation HER2 status in gastric adenocarcinoma of Chinese and contributing factors to the HER2 expression. Methods: HER2 status of 40 842 gastric adenocarcinomas and clinical data were retrospectively collected from 23 hospitals dated from 2013 to 2016. The association between HER2 positivity and clinicopathologic features was analyzed. Results: Of the 40 842 patients the median age was 62 years, the male female ratio was 2.6∶1.0. The rate of HER2 positivity was 8.8% (3 577/40 842). HER2 expression was related to the tissue type, tumor location, Lauren classification and tumor differentiation (P values: 0.009, 0.001, <0.01 and <0.01, respectively). Different HER2 expression status was observed between primary and recurrent tumors in 7.6% (48/635) cases. The rates of HER2 positivity ranged from 2% to 10% among different institutions. The rates of HER2 FISH amplification were dramatically different among the 23 hospitals (0-100%) with an average rate of 10% (810/8 156) in patients with HER2 IHC 2+ . Conclusions: HER2 expression is associated with clinicopathologic characteristics. HER2 re-assessment of tumor tissue and use of in situ hybridization techniques increase HER2 positivity. The current retrospective study should reflect the HER2 status in gastric adenocarcinoma of Chinese patients.

Abstract
Objective We compared failure patterns and survival after elective nodal irradiation (eni) or involved-field irradiation (ifi) in patients with thoracic esophageal squamous cell carcinoma (escc), clinical stage T2-4N0M0, to determine whether ifi is feasible for such patients. Methods Between 2005 and 2015, 126 patients with clinical stage T2-4N0M0 thoracic escc who received definitive concurrent chemoradiotherapy in Shandong Cancer Hospital and Institute and who had complete data, were analyzed retrospectively. Of those patients, 49 received ifi, and 77 received eni. In the ifi group, the radiation field included the primary tumour, with a 3-cm to 4-cm margin in the craniocaudal direction, and the elective irradiation was delivered to the adjacent regional lymphatics according to the location of the primary tumour. Patterns of failure were classified using the first site of failure, which included primary tumour failure, regional lymph node failure, and distant metastasis. Results Median progression-free survival was 20 months [95% confidence interval (ci): 7.87 months to 39.2 months] in the ifi group and 30 months (95% ci: 17.4 months to 44.6 months) in the eni group (p = 0.580). Median overall survival (os) was 36 months (95% ci: 21.9 months to 50.1 months) in the ifi group and 38 months (95% ci: 26.1 months to 49.9 months) in the eni group (p = 0.761). The estimated 1-year, 3-year, and 5-year os rates were, respectively, 87.8%, 49.4%, and 32.3% for the ifi patients and 92.2%, 52.0%, and 28.9% for the eni patients. Disease persistence and primary lesion recurrence after complete remission (cr) were the most frequent causes of treatment failure in the patients overall (83 of 124, 66.9%). Of the 66 patients achieving a clinical cr, 25 experienced recurrence of the primary lesion, 12 experienced distant relapse, 10 experienced regional nodal failure, and 2 experienced an isolated recurrence. No significant differences in the pattern of failure or in the incidences of grade 3 or greater treatment-related myelosuppression or esophagitis were found between the ifi and eni groups. Conclusions In patients with thoracic escc clinical stage T2-4N0M0 receiving definitive chemoradiotherapy, failure patterns and os were similar with either eni or ifi. Large prospective randomized studies are needed to further investigate and verify those results in this subgroup of patients.

Abstract
Plastic deformation of metallic glasses (MGs) has long been considered to be confined to nanoscale shear bands, but recently an affected zone around the shear band was found. Yet, due to technical limitations, the shear-band affected zone (SBAZ), which is critical for understanding shear banding and design of ductile MGs, has yet to be precisely identified. Here, by using magnetic domains as a probe with sufficiently high sensitivity and spatial resolution, we unveil the structure of SBAZs in detail. We demonstrate that shear banding is accompanied by a micrometer-scale SBAZ with a gradient in the strain field, and multiple shear bands interact through the superimposition of SBAZs. There also exists an ultra-long-range gradual elastic stress field extending hundreds of micrometers away from the shear band. Our findings provide a comprehensive picture on shear banding and are important for elucidating the micro-mechanisms of plastic deformation in glasses. Metallic glasses deform along nanoscale shear bands, and while it is known that they affect the neighboring glass regions, exactly how is unclear. Here, the authors use magnetic force microscopy to atomically resolve the shear-band affected zone and show its effects extends much further than previously thought.

Abstract
Objective:To explore the clinical value of MDCT and post-processing in children with suspected foreign body in trachea.Method:Two hundred patients with suspected tracheal foreign body were treated with 64-slice spiral CT (MDCT) and simulated endoscopic imaging,then compared with seen in bronchoscopy; Compare the results of MDCT and post-processing with the coincidence of intraoperative findings.Result:One hundred and eighty-four cases of positive children were examined by MDCT postprocessing technique and bronchoscopy,179 cases were obstructed by exogenous foreign body,5 cases were phlegm thrombosis (endogenous foreign body) obstruction; 16 cases of children with no foreign body diagnosed by MDCT post-processing technique were also examined by bronchoscopy. The results showed that there was a foreign body in 1 case,and the foreign body was located in the pharyngeal cleft (watermelon spermoderm),and the remaining 15 cases had no foreign body. MDCT and post-treatment techniques for children with tracheal foreign body diagnosis of 99.4% sensitivity,specificity of 75%.There was no significant difference in the detection rate of foreign body between the two techniques of MDCT and post-processing technique and bronchoscopy (P>0.05). Examed by MDCT and postprocessing,we can understand the specific location and size of foreign body,nature,shape preoperatively.Conclusion:Although MDCT and post-processing techniques can not be used to treat tracheal foreign bodies,but the diagnostic rate of bronchial foreign bodies is comparable to that of bronchoscopy. We could apply MDCT examination and post processing before the bronchoscopy,for foreign body inhalation history is not clear,or suspected airway foreign body. We can improve the level of diagnosis and treatment through guiding the operation of bronchoscopy focus.

Abstract
Objective: To study the relationship between the weight change trend of initial treatment patients with pulmonary tuberculosis and the dose change trend of isoniazid, and therefore to analyze the appropriate dose of isoniazid. Methods: Data of initial treatment inpatients with pulmonary tuberculosis from May 1955 to December 2012 were retrospectively analyzed. Elderly patients with pulmonary tuberculosis, patients with drug-resistant tuberculosis, extrapulmonary tuberculosis and those with complications were excluded from the study. The time period was separated as 20th century 1950s to 1960s, 1970s, 1980s, 1990s, 21th century 2000s and 2010s. Samples were selected in each year and month between 1950s to 1960s and 1970s. After 1980s, samples of 1 year were taken from each 5 years. The sex, age and weight for every patient were collected, as well as the dose of isoniazid of every inpatient on a day in therapeutic regimen. Meanwhile, the weight change trend of the patients in different ages and the dose change trend of isoniazid were compared. The total number of cases was 1 398, with 924 males and 474 females, averaging (36.7±14.4) years old. Results: The weight of the patients increased when it was compared between that in 1950s to 1960s, 1970s or 1980s and that in 2000s, with a increasing weight of 3 kg, 3.5 kg and 3 kg respectively. The difference showed statistical significance (P<0.003). The difference was also significant when the weight in 70s was compared with that in 2010s (P=0.002). The therapeutic dose of isoniazid remained invariable regardless of the weight change. At 1990s, 2000s and 2010s, the dose of isoniazid per kilogram of body weight would reduce to 0.005 4 g, 0.005 2 g and 0.0054 g relative to patients' weight increase, and the difference was statistically significant (P<0.001). Conclusions: The weight of pulmonary tuberculosis inpatients increased in recent 60 years. The weight has a close relation with the dose of isoniazid. A fixed dose of isoniazid (0.3 g/d) regardless of the weight change could result in low blood drug concentration . To avoid tolerance of isoniazid and increase the cure rates of pulmonary tuberculosis, the dosage of isoniazid should be increased based on the weight increase of patients.

Abstract
Objective: To study the clinicopathologic characteristics, immunophenotype, pathologic diagnosis and differential diagnosis of myxoid adrenocortical adenomas. Methods: The clinical data, histological features and immunohistochemical results of 4 cases of myxoid adrenocortical adenomas were analyzed, which were collected from January 2014 to December 2016 at Guangdong General Hospital, with review of literature. Results: Four cases of myxoid adrenocortical adenomas were presented. The patients ages ranged from 26 to 45 years (mean =35 years). Microscopically, it showed a typical morphology, characterized by small-sized tumor cell cords or pseudo-glands embedded in an abundant extracellular myxoid matrix. Immunohistochemical staining showed tumor cells were strongly positive for Melan A, vimentin and focally for α-inhibin, one case showed strong and diffuse positivity for CAM5.2, and two cases showed diffuse positivity for synaptophysin, while negative for CgA, S-100 protein, epithelial antigen, CK7, CK20 and CKpan. Conclusions: Myxoid adrenocortical adenomas are extremely rare, which may cause confusion with metastatic well-differentiated neuroendocrine tumours, sex cord-stromal tumoursor metanephric adenoma. Recognition of this entity would be beneficial for pathologists to avoid misdiagnosis, and unnecessary treatment.

Abstract
Objective: To investigate the snoring status of school-aged children in Beijing and explore the association of snoring and academic performance. Methods: A total of 7 925 children aged from 6 to 14 were selected from 15 primary and middle schools at 7 districts (Xicheng, Chaoyang, Changping, Shunyi, Fangshan, Huairou and Mentougou) in Beijing in 2015, using multi-stage stratified cluster random sampling method. The recruited children were asked to complete the Pediatric Sleep Questionnaire (PSQ) and a questionnaire related to sleep behavior. The multiplelogistic regression was used to analyze the association of snoring and academic performance. Results: A total of 794 (12.44%) children showed a decline in academic performance among 6 383 eligible respondentsfor data analysis. 580 (9.08%) children with snoring was identified, of which 333 and 247 were in frequency of 1-2 times per week and frequency of ≥3 times per week, respectively; 357, 170 and 53 were in snoring grade Ⅰ, grade Ⅱ and grade Ⅲ, respectively. Compared with the children without snoring, the OR (95%CI) for children with 1-2 times per week and ≥3 times per week was 1.363 (1.000-1.857) and 1.605 (1.135-2.269), respectively; and the OR (95%CI) for children with grade Ⅰ, grade Ⅱ and grade Ⅲ of snoring was 1.226 (0.893-1.683), 1.595 (1.062-2.397) and 2.31 (1.17-4.565), respectively. Conclusion: There is a statistical relationship between snoring and the decline of academic performance. The decline of academic performance positively associated with increased frequency and grade of snoring.

Abstract
Herein, we report a case of a 34-year-old woman with systemic sclerosis (SSc)-rheumatoid arthritis (RA) overlap syndrome (OS) complicated with Sweet's syndrome. OS has been defined as entities satisfying classification criteria of at least two connective tissue diseases (CTD) occurring at the same or at different times in the same patient. The CTD include RA, SSc, systemic lupus erythematosus (SLE), polymyositis, and dermatomyositis. Sweet's syndrome also known as acute febrile neutrophilic dermatosis was first described by Robert Sweet in 1964. Sweet's syndrome is characterized by fever, neutrophilia, erythematous skin lesions, and a diffuse dermal infiltrate of mature neutrophils. There are sets of associations that we will discuss in this article between OS and Sweet's syndrome.

Objective:To investigate the clinical features, diagnosis and treatment experience of basal cell adenoma (BCA).Method:The clinical data of 7 patients with basal cell adenoma of the parotid gland from the Second Affiliated Hospital of Medical University of Anhui from March 2012 to June 2016 were retrospectively analyzed. Combined with literature review, the experience of diagnosis and treatment was discussed.Result:Seven BCA were mostly diagnosed as pleomorphic adenoma and adenomatous lymphoma before operation using parotid ultrasound, fine needle aspiration cytology and parotid enhanced CT, and no patients was diagnosed as BCA prior to the operation. Four cases were diagnosed as BCA, 1 case was diagnosed as adenoma, 1 case was diagnosed as low-grade malignant tumor, and 1 case was not able to identify benign or malignant tumor by intraoperative fast frozen pathological examination. There were no obvious complications after the operation, and only 2 cases of mild facial paralysis returned to normal in 1 month, and no recurrence was found in the follow-up 18-69 months. Conclusion:Basal cell adenoma of the parotid gland is a rare benign tumor of parotid gland, the lack of specific clinical manifestations and signs, preoperative ultrasonography, fine needle aspiration cytology and parotid gland enhanced CT scan can not confirm the diagnosis, although they have some limitations, they are of great value in the localization, qualitative and differential diagnosis of BCA in the parotid gland. The diagnosis mainly depends on intraoperative, postoperative pathology and immunohistochemical examination. The treatment is mainly surgical excision, and the prognosis is better.

Abstract
Objective:To evaluate the clinical assessment of regional resection and superficial lobe total resection in the treatment of benign tumors of the parotid gland. Method:One hundred and nighty-five patients operated in the First Hospital of Peking University from January 1998 to March 2017 with benign tumor of the parotid gland were retrospectively analyzed. There were 189 patients with single side tumor and 6 patients with bilateral sides, 157 cases underwent regional resection and the other 44 cases underwent superficial lobe total resection. All the results and complications were recorded and analyzed between the two groups.Result:There were total 195 patients with 201 cases. All the complications were as follows, 4 cases with recurrence, 44 cases with temporal facial paralysis, 13 cases with permanent facial paralysis, 80 cases with earlobe numbness, 49 cases with facial numbness, 44 cases with skin retraction, 26 cases with operated region effusion, 2 cases with sialosyrinx, 55 cases with Frey syndrome. There were no significant differences between the two groups in the incidences of recurrence, temporal facial paralysis, permanent facial paralysis, earlobe numbness, facial numbness, skin retraction. The incidence of Frey syndrome in the superficial lobe total resection group was significantly higher than the regional resection group(45.5%, 22.3%,P<0.05). The incidence of operated region effusion or sialosyrinx in the regional resection group was significantly higher than the superficial lobe total resection group (16.6%, 4.5%,P<0.05),further analysis showed that the operation method and the location of the tumor were the independent risk factors. Conclusion:Regional resection in the parotid gland tumor was less invasive, the incidences in the most complications were in consistent with superficial lobe total resection, and it was helpful in preventing the occurrence of Frey syndrome. Although regional resection conserved more parotid gland tissue so that the more conserved gland function and it also did not increase the incidence of sialosyrinx, the operated region effusion was significantly increased. If the operated region effusion was not discovered and handled, there would be a risk of sialosyrinx.

Abstract
Carcinoma ex pleomorphic adenoma is an epithelial malignant tumor of pleomorphic adenoma. This may be due to the accumulation of genetic instability caused by long-term pleomorphic adenomas. There are few reports of parapharyngeal space carcinoma ex pleomorphic adenoma in the literature study both at home and abroad. This article retrospectively summarized the clinical data of 1 case of pharyngeal space carcinoma ex pleomorphic adenoma and reviewed the literature. We strengthened the understanding of parapharyngeal space carcinoma ex pleomorphic adenoma, improve the accuracy of diagnosis and reduce misdiagnosis and mistreatment.

Abstract
Glutamine is the most abundant amino acid found in plasma and cells. It is the preferred fuel for enterocytes in the small intestine, macrophages, and lymphocytes. After serious burn, increased requirement of glutamine by the gastrointestinal tract, kidney and lymphocytes, and relatively insufficient self synthesis likely contribute to the rapid decline of glutamine in circulation and cells. Glutamine supplementation can not only protect intestinal mucosa, maintain normal intestinal barrier function, reduce bacterial translocation, and enhance the intestinal immune function, but also increase the number of lymphocytes, enhance the phagocytic function of macrophage, promote the synthesis of immunoglobulin, and reduce the body's inflammatory response, so as to enhance the immune function. Therefore, glutamine supplementation can improve and enhance the immune function, reduce complications and promote the prognosis of severely burned patients.

Abstract
Objective: To evaluate the expression of βF1 and T cell receptor (TCR)γ in T lymphoblastic lymphoma/leukemia(T-LBL/ALL), and investigate the clinicopathological features. Methods: Fifty-one cases of T-LBL/ALL were collected at Guangdong General Hospital from 2010 to 2016, the expression of βF1 and TCRγ was assessed by immunohistochemistry. Results: There were 13 cases of children and adolescents, and 38 cases of adults. The expression rates of βF1 and TCRγ were 27.5%(14/51) and 15.7%(8/51) respectively. The proportion of adults in αβ T-LBL/ALL, TCR-silent T-LBL/ALL and γδ T-LBL/ALL was 7/14, 79.3%(23/29)and 8/8 respectively, and the difference was significant (P=0.023). There was no statistical difference in sex, LDH, bone marrow involvement and Ann arbor stage among these three groups(P>0.05). γδ T-LBL/ALLs included 6 cases of CD4(-)/CD8(-) phenotype, whereas αβ T-LBL/ALL included 7 cases of CD4(+) /CD8(+) phenotype. There was significant difference in CD4/CD8 expression among these three groups(P<0.01). Conclusions: γδ T-LBL/ALL occurred only in adults, with predominantly CD4(-)/CD8(-) phenotype. αβ T-LBL/ALL occurred more common in children and adolescents, with predominantly CD4(+) /CD8(+) phenotype.

Abstract
Objective: To carry out a prospective cohort study of combined intra-operative radiotherapy for centrally located hepatocellular carcinomas (HCC) and to observe the safety and postoperative complications. Methods: A total of 79 patients with centrally located HCC who underwent hepatectomy were divided into two groups: experimental group (combined with targeted intra-operative radiotherapy, 32 cases) and control group (single surgical operation, 47 cases). Patients in the experimental group received intra-operative electron radiotherapy after tumor resection, while patients in the control group received to intra-operative electron radiotherapy.The haemorrhagia amount and operation time during the operation, intra-operative liver function and the recovery of liver and gastrointestinal tract of patients in these two groups were compared. Results: No postoperative 30-day mortality was observed in all of the patients. The average total operation time of patients in the experimental group was (319±76) min, significantly longer than (233±76) min of the control group (P<0.001). The average aspartate transaminase (AST) level of patients in the experimental group at postoperative day 1 was 562.5 U/L, significantly higher than 347.0 U/L of control group (P=0.031). However, the average prothrombin activity levels of patients in the experimental group at postoperative day 3 and day 7 were (68.3±17.9)% and (73.4±10.2)%, respectively, significantly lower than (78.9±15.9)% and (80.0±10.6)% of control group (both P<0.05). There were no significant differences of tumor volume, differentiation degree, satellite lesion, dorsal membrane invasion, microvascular invasion between these two groups (all P>0.05). There were no significant differences of hospital stay, ventilation time, the incidence of hepatic insufficiency, ascites, pleural effusion, infection, biliary fistula between these two groups (all P>0.05). There were no significant differences of alanine aminotransferase (ALT), albumin, total bilirubin between these two groups at postoperative day 1, 3, 5 and 7 (all of P>0.05). Conclusion: The resection of centrally located HCC combined with intra-operative radiotherapy may increase the total operation time, delay the early postoperative recovery of liver function, but it is still safe and feasible.

Abstract
Allergic rhinitis (AR) is the Th2 inflammatory response that atopic individuals exposure to allergens, mediators released by IgE-mediated, and a variety of immunocompetent cells and cytokines involved .Group 2 innate lymphoid cells (ILC2) are a novel population of native lymphocyte, can secrete large amounts of Th2 cytokines to promote the development of allergic diseases after being activated. MiR-155 plays a vital role in the development of the immune system, the differentiation of immune cells, and the maintenance of immune function.Nasal mucosas from the patients with allergic rhinitis show enrichment for ILC2 and miR-155. Highly expressed miR-155 may enhance the level of IL-4 by promoting ILC2 expression, thereby promoting Th2 inflammatory response.This review focuses on the function and meaning of ILC2 and miR-155 in patients with Allergic rhinitis.

Abstract
Objective:To investigate the effect of CCR3 gene knockout on the proliferation, maturation and apoptosis of eosinophils (EOS) in mice. Method:Bone marrow cells from CCR3 gene knockout mice (experimental group) and wild-type mice (control group) were cultured in vitro and induced differentiation into mature EOS. EOS proliferation was observed by cell counting.Expression of degranulation protein mRNA was detected by qRT-PCR. EOS apoptosis was detected by Annexin V-FITC/PI double staining method. Result:①The number of cells on the 0-14 day of EOS cultured in vitro showed that the number of cells in the experimental group was less than that in the control group at tenth, twelfth, fourteenth days, and the proliferation was slower, the difference was statistically significant (P<0.01). ②The test results of EOS cells apoptosis showed that, under the condition of containing 10 ng/ml IL-5 or no IL-5, the apoptosis rate of EOS cells in experimental group was higher than that in normal control group, the difference between both groups was statistically significant (P<0.01). ③The expression results of ECP, EPO, MBP mRNA in EOS showed that the expression levels of ECP, EPO, MBP mRNA in the experimental group compared with the normal control group were reduced in varying degrees, the difference between both groups was statistically significant (P<0.05). Conclusion:Knockout CCR3 gene can inhibit the proliferation and maturation of EOS and promote its apoptosis, which provides a theoretical basis for CCR3 as a target gene to treat allergic rhinitis.

Abstract
OBJECTIVE To evaluate the bonding ability of one representative self-etch adhesive system by applying the micro-shear bond strength test method with different concentrations of carbodiimide [1-ethyl-3-(3-dimethylaminopropyl) carbodiimide, EDC] ethanol solution pretreatment. METHODS Extracted sound human third molars were collected from patients ranging 18 to 40 years. In the study, 80 molars were first sectioned to prepare a flat middle coronal dentin surface and then were randomly divided into 5 groups (n=16) according to without/with different surface treatments [blank control; 80% (volume fraction) ethanol control; EDC ethanol solution of three concentrations (0.01 mol/L, 0.3 mol/L and 0.5 mol/L)]. Each specimen underwent a micro-shear bond strength test and failure mode observation. The data collected were subjected to statistical analysis using one-way ANOVA and post hoc Tukey's test to analyze the difference of the micro-shear bond strength, and chi-square test/Fisher's exact test for the failure mode frequency of the micro-shear bond strength test specimens at a significance level of P=0.05. RESULTS The micro-shear bond strength of the three concentration EDC treatments were (35.29±8.97) MPa (0.01 mol/L EDC treatment group), (40.24±9.68) MPa (0.3 mol/L EDC treatment group), (37.38±9.66) MPa (0.5 mol/L EDC treatment group) separately; and that of the 80% ethanol group was (37.49±7.76) MPa. All micro-shear bond strength value of the above four groups was statistically higher than that of the blank control group [(33.81±7.98) MPa]. The immediate micro-shear bond strength and failure mode was of no statistically significant difference among all the groups. It was noticed that the immediate micro-shear bond strength of 0.3 mol/L was higher than that of all the other groups, especially higher than that of the 80% ethanol pretreatment group despite that there was no significant difference among all the groups. And the test of failure mode indicated that the cohesive failure was more common, while the frequency of adhesive failure was rare in each experimental group. CONCLUSION EDC pretreatment had no adverse effect on the immediate micro-shear bond strengths of Clearfil SE Bond. Meanwhile, EDC treatment did not cause more adhesive failure in immediate micro-shear test, which had further denoted what was said above. However, it needs more research to illustrate the anti-enzymatic role of EDC in dentin bonding.

Abstract
Objective To investigate whether sustained abdominal aorta compression (SAAC) can improve coronary perfusion pressure (CPP) during cardiopulmonary resuscitation (CPR) and improve resuscitation outcomes without causing liver laceration. Design and Setting Animal study. Methods Cardiac arrest was induced by asphyxia in 28 New Zealand rabbits and maintained for 2 minutes before resuscitation. Animals were resuscitated using either standard CPR (STD-CPR group) or standard CPR and SAAC (SAAC-CPR group). Restoration of spontaneous circulation (ROSC), restoration of spontaneous breathing (ROSB) and cerebral performance category score were determined. CPP, mean arterial pressure (MAP) and ROSC were compared in the two groups. Results MAP and CPP in the SAAC-CPR group were significantly higher than in the STD-CPR group. However, MAP and blood gas results showed no significant difference between the two groups during ROSC. ROSC was achieved in seven of fourteen animals in the STD-CPR group and in eleven of fourteen animals in the SAAC-CPR group. Five animals in the STD-CPR group and nine in the SAAC-CPR group survived 24 hours after ROSC. No liver injury occurred in the two groups. Conclusions SAAC-CPR produces an increased CPP and MAP than traditional CPR and it does not lead to liver laceration/injury.

Abstract
Objective:To evaluated the clinical anatomy of the inferior thyroid arteries and veins and the safety of clinical application of the modified tracheotomy. Method:Sixty patients who need partial resection or full resection of thyroid cancer and 50 patients with laryngeal or hypopharyngeal cancer required tracheotomy were enrolled in this study. The distribution of the inferior thyroid arteries and veins closely related to tracheotomy is further dissected. The inverted "U" type of tracheal flap tracheotomy was further improved based on anatomical findings. Finally, the further modified tracheotomy was used for clinical practice and compared with the conventional tracheotomy and the inverted "U" type of tracheal flap tracheotomy. Result:Of the 110 cases, the lowest thyroid artery was found in 11 cases, with a rate of 10%. The inferior thyroid vein has 2-4 branches, which originates from the lower lobe or isthmus of the thyroid lateral lobe, descending in the anterior tracheal space. According to the characteristics of the static reflux of the thyroid gland, the lower thyroid vessels are classified into four types: intravenous dry type (28 cases); intravenous double dry without traffic type (43 cases); intravenous double trunk with traffic (28 cases); mixed type (11 cases). At present, the further modified tracheotomy can effectively avoid the rebleeding of the lower thyroid arteries and veins. There were no bleeding and other complications in all cases. Conclusion:It provides a basis for the further modified of tracheotomy based on the clinical anatomy of the inferior thyroid artery and vein, which is closely related to tracheotomy. The further modified tracheotomy has certain advantages than the conventional tracheotomy and the inverted "U" type of tracheal flap tracheotomy.
