Abstract
Objective: Thecurrent study is to explore the neuron-protective mechanism of neuregulin1β (NRG1β) in a rat model of middle cerebral artery occlusion/reperfusion (MCAO/R) through inhibiting the c-Jun phosphorylation. Methods: After 24 h of MCAO/R (referring to Longa's method), neurobehavioral function was measured by modified neurological severity score (mNSS) test; the cerebral infarction volume was detected by triphenyltetrazolium chloride (TTC) staining; the blood brain barrier (BBB) permeability was measured by Evans Blue (EB); the neuron morphology of brain tissue was observed by Nissl stain; the ultra-structures of the neurons were observed by transmission electron microscopy (TEM); the apoptotic neurons were counted by in situ cell death detection kit colocalized with NeuN; the expressions of phospho-c-Jun was determined by immunofluorescent labeling and Western blot analysis. Results: Compared with the sham-operation rats, the rats receiving MCAO/R showed increased mNSS (9.7±1.2), cerebral infarction volume (41.4±3.0)%, permeability of BBB, deformation of neurons, ischemia-induced apoptosis (0.63±0.04), and enhanced expression of phospho-c-Jun protein (0.90±0.07) (all P<0.05). Our data indicated that NRG1β attenuated neurologic deficits (6.4±0.9), decreased the cerebral infarction volume (10.4±0.5), reduced EB extravasation (1.55±0.13) and the deformation of neurons, protected the ultra-structure of neurons, blocked ischemia-induced apoptosis (0.23±0.02), through down-regulated phospho-c-Jun expression (0.40±0.03) in MCAO/R rats (P<0.05). Conclusion: NRG1β exerts neuron-protective effects against ischemia reperfusion-induced injury in rats through inhibiting the c-Jun phosphorylation.

Abstract
Purpose Chronic hepatitis C virus (HCV) infection is reported to be associated with early-onset breast cancer, while, as a hepadnavirus, hepatitis B virus(HBV) infection is more common than HCV in China. In this article, it is aimed to study the relationship between HBV infection and risk of breast cancer in China. Methods The clinical data of 2452 cases of initially diagnosed breast cancer and 1926 cases of benign breast disease (as controls) with the consecutive reports of HBV serological markers and liver function tests, available in the Electronic Medical Records of the Breast Cancer Center of Chongqing, the southwest of China, from January 2011 to March 2015, were collected for analysis. Results The average age of the initially diagnosed breast cancer patients was 50.3±11.3 years with the age peaking about 40- 49yeaers (39.7%). The positive rate (8.2%) of hepatitis B surface antigen in breast cancer patients was relatively higher than that (7.8%) in controls (P>0.05). While, the positive rate (66.4%)of hepatitis B core antibody in breast cancer patients was significantly higher than that (53.7%) in controls (P<0.05), so were the similar results in the age groups of 40-49 years, after multiple layer analysis stratified by age and compare HBV markers adjusting age with binary logistic regression. Meanwhile, the status of albumin, aminotransferase and aspartate transaminase (41.4 g/L, 22.9 U/L, 22.0 U/L) in breast cancer patients were significantly poorer than those (44.1 g/L,16.8 U/L, 19.2 U/L) in controls (P<0.05). Conclusions Exposure to HBV infection may be a risk factor for breast cancer and may be also related to the earlier age onset of breast cancer (peaked around 40-49 years) among Chinese females.

Abstract
Objective: To evaluate and compare the efficacy between posterior fossa decompression without duraplasty (PFD) and posterior fossa decompression with duraplasty (PFDD) in the surgical management for adult Chiari Ⅰ malformation. Methods: Fifty-seven patients suffered from Chiari malformation type Ⅰ were treated in Department of Neurosurgery, Henan Provincial People's Hospital from August 2008 to October 2013. Twenty-three patients received posterior fossa decompression without duraplasty and the other 34 patients received posterior fossa decompression with duraplasty. The clinical results were retrospectively analyzed to compare the efficacy of two different surgical approaches. Results: There was no death or severe neurological dysfunction case in 57 patients of the two groups. Patients undergoing PFD had shorter length of hospital stay[(13.7±3.5) d vs (16.2±4.1) d, P<0.05]and surgical time[(98.7±22.1) min vs (132.3±39.6)min, P<0.05]. Cerebrospinal fluid-related complications and intracranial infection were more common in patients undergoing PFDD[(0/23, 0) vs (8/34, 23.5%), P<0.05]. Clinical improvement was comparable in two groups[(15/23, 65.2%) vs (26/34, 76.5%), P>0.05]at the one-year follow-up. The rate of syrinx regression in patients with Syringomyelia was higher in patients undergoing PFDD[(3/12, 25%) vs (17/22, 77.3%), P<0.05]. Conclusion: For adult patients with Chiari malformation type Ⅰ, PFD has the advantages of simple manipulation, short length of hospital stay and low incidence of cerebrospinal fluid-related complications and intracranial infection, compared with PFDD. It is comparable to PFDD in clinical improvement, but the effect of PFD is not as good as that of PFDD in the aspect of syrinx regression.

Abstract
Objective: To investigate the relativity between the distribution of deep medullary vein (DMV) in patients with middle cerebral artery stroke and clinical prognosis by using susceptibility-weighted imaging (SWI). Methods: A total of 144 cases of middle cerebral artery stroke patients and 55 healthy volunteers were retrospectively analyzed from January 2015 to October 2015 in order to investigate the symmetrical characteristic and the classification of DMV, then 30 cases were followed up. Kappa test was used to consider the consistency of judging DMV symmetry and type data by two radiologists. Results:Kappa value in DMV symmetry and DMV type were 0.875 and 0.852. Chi-square test analysis revealed a statistically significant difference of DMV symmetry between healthy control and stroke group(χ(2)=31.046, P=0.000). There was correlation between DMV type and NIHSS score in stroke group (r(s)=0.208, P=0.025). There was no statistically significant difference of DMV distribution in the different periods of stroke group (P=0.110). But there was statistically significant difference of DMV distribution between acute and chronic stroke (P=0.018). Among 30 follow-up cases, 18 cases with asymmetry DMV changed into symmetry after stroke therapy. In 8 cases with symmetry DMV, the diameter of DMV became smaller after treatment. In 4 cases, DMV had no changes. Conclusions: DMV in patients of MCA stroke are mostly asymmetry distribution. DMV classification can be used as an imaging standard to predict the prognosis of stroke patients.

Abstract
Operating room (OR) nursing previously referred to patient care provided during the intra-operative phase and the service provided within the OR itself. With the expansion of responsibilities of nurses, OR nursing now includes pre-operative and post-operative periods, therefore peri-operative nursing is accepted as a nursing process in OR in the contemporary medical literature. Peri-operative nurses provide care to the surgical patients during the entire process of surgery. They have several roles including those of manager or a director, clinical practitioner (scrub nurse, circulating nurse and nurse anesthetist), educator as well as researcher. Although, utmost priority is placed on insuring patient safety and well-being, they are also expected to participate in professional organization, continuing medical education programs and participating in research activities. A Surgical Patient Safety Checklist formulated by the World Health Organization serves as a major guideline to all activities in OR, and peri-operative nurses are key personnel in its implementation. Communication among the various players of a procedure in OR is key to successful patient outcome, and peri-operative nurses have a central role in making it happen. Setting up of OR in military conflict zones or places that suffering a widespread natural disaster poses a unique challenge to nursing. This review discusses all aspects of peri-operative nursing and suggests points of improvement in patient care.

Abstract
Objective:To investigate the abnormal functional response of neural pathways of vestibular migraine (VM) patients, located the functional area, and inferred the possible mechanism. Method:Twenty patients of VM, 20 of migraine without aura (MwoA), and 20 of healthy controls (HC), underwent whole-brain blood oxygen level-dependent (BOLD) fMRI during ear irrigation with cold water. We chose the stimulation image and the diapause stimulation image. Analyses explored functional area with BOLD signal change of the three groups. Result:We observed task-positive BOLD signal change in cortical and subcortical pattern in response to ear irrigation of all participants. Such as parietal lobe, temporal lobe, insular lobe, cingulate gyrus, thalamus, caudate nucleus, optic radiation, precuneus. VM patients showed a significantly task-negative in thalamic and fusiform gyrus in comparison with the other groups (P<0.05). Conclusion:fMRI could response the respective functional area objectively. We inferred the possible mechanism of VM was abnormal activation of thalamus and fusiform gyrus, produced crossing between the vestibular sensory pathway conduction and the pain conduction.

Abstract
There are Seven Medical Classics recorded in the Han shu Yi wen zhi(Bibliography in Annals of the Han Dynasty), among which the 18-volume Huang di nei jing (Huangdi's Internal Classic) is not the current edition of Ling shu (Miraculous Pivot) and Su wen(Plain Questions). The present edition of Huang di nei jing containing these two works might be merged in the Eastern Han Dynasty, benefited from the invention of Cai Lun's papermaking technique and the development of Nine needles, especially filiform needle manufacturing. Huang di nei jing was compiled on the basis of two major integrations: The first was joined by some medical experts such as Bian Que and tai yi ling (minister of imperial physicians) of the Qin State by using the language in the Warring States, contributing mainly to the theoretical system and forming its basic academic framework; The second was the second Royal book-collating activity in the Eastern Han Dynasty (100-110), which had revised the seven volumes of Chinese Medical Classics and incorporated them into two parts, Ling Shu and Su Wen, together with Bian Que's medical works and the new contents from the introductory Chapter on Nine Needles and Twelve Yuan(origin) Acupoints.

Abstract
Objective: To evaluate the level of lexiscan-induced blood-brain barrier opening of healthy rabbits via CT perfusion weighted imaging (PWI) scan. Methods: Between November 2014 and May 2015, thirty New Zealand white rabbits were randomly assigned into three groups: the experimental group A1 which received one injection of lexiscan(1 ml/kg); the experimental group A2 which received three times injection of lexiscan(total dose: 1.5 ml/kg), finished within 15 minutes; the control group B which was injected the same volume normal saline(1 ml/kg), after 30 minutes, CT PWI scan was performed. Then cerebral blood flow (CBF), cerebral blood volume (CBV), mean transit time (MTT) and permeability surface(PS) of the region of interest of each group were acquired and compared statistically. Five cases of each group were injected with 2% Evans blue intravenously posterior to imaging. After one hour of infusion, all the animals were killed. Their brains were examined for the determination of Evans blue distribution. Results: Both the values of CBF and CBV and the staining with Evans blue of the group A1(CBF: (89.88±2.21), (81.42±4.28) ml·(100 g)-1·min-1; CBV: (3.97±0.43), (3.66±0.16) ml/g)and group A2 (CBF: (75.16±0.84), (63.66±7.21) ml·(100 g)-1·min-1; CBV: (4.07±0.01), (3.75±0.05) ml/g) were higher than those of the group B(CBF: (20.08±5.08), (14.58±8.62) ml·(100 g)-1·min-1; CBV: (0.85±0.04), (0.65±0.17) ml/g), the differences were all statistically significant (all P<0.01). While there was no statistically difference between group A1 and group A2(P>0.05). The value of PS of the group A2((22.43±8.09), (20.20±7.01)ml·(100 g)-1·min-1 )was higher than that of group A1((13.82±4.44), (10.12±2.44)ml·(100 g)-1·min-1) and group B(0.00, 0.00)(the lowest one), the differences were all statistically significant(all P<0.01). The value of MTT of the group A1((2.50±0.82, 2.47±0.10) s) had no statistical difference with group A2 and group B, while the value of group A2((4.50±0.17), (4.72±0.15) s) was higher than that of group B((1.88±0.09), (1.99±0.00) s), the differences were all statistically significant (P<0.05). Conclusion: Changes in hemodynamics of lexiscan-induced blood-brain barrier opening can be monitored by CT PWI scan. When the total dose of lexiscan increasing, the level of the BBB opening is higher with significantly increased CBF, CBV, PS and MTT.

Abstract
Objective: To evaluate the values of enhanced CT and MRI for the diagnosis of thyroid cartilage invasion by laryngeal and hypopharyngeal cancer. Methods: One hundred and ninety-seven patients with primary laryngeal or hypopharyngeal cancer treated with surgery between January 2013 and December 2014 were included in this study. All patients underwent enhanced CT and MRI before surgery. With MRI using the techniques of fast recovery fast spin echo (FRFSE), spin echo echo planar imaging (SE-EPI) and diffusion weighted imaging (DWI), thyroid cartilage invasion was evaluated and the results of postoperative histopathological examination was used as a gold standard for the determination of thyroid cartilage invasion. The sensitivity, specificity, positive predictive value and negative predictive value of enhanced CT or MRI in detecting thyroid cartilage invasion by laryngeal and hypopharyngeal cancer were evaluated. Data were analyzed with SPSS17.0 software. Results: Among 197 patients, there were 35 cases with supraglottic laryngeal cancer, 92 cases with glottic laryngeal cancer, 9 cases with subglottic laryngeal cancer, and 61 cases with hypopharyngeal cancer. Postoperative pathologycal examinations showed that 63 (32.0%) of 197 patients had thyroid cartilage invasion by tumor. Based on TNM classification of AJCC (American Joint Commission for Cancer, 2010), there were 36 cases at T2 stage, 109 cases at T3 and 52 cases at T4; 117 cases with N0, 46 cases with N1 and 34 cases with N2. The sensitivity, specificity, positive predictive value and negative predictive value of CT for the detection of thyroid cartilage invasion were respectively 57%, 86%, 65% and 81%, and those of MRI were respectively 94%, 87%, 78% and 97%. Kappa values were 0.45 for CT and 0.77 for MRI in diagnosis of thyroid cartilage invasion, with statistically significant difference (χ(2)=6.78, P<0.05). Conclusion: MRI (FRFSE and SE-EPI DWI) has more advantages than CT in the diagnosis of thyroid cartilage invasion by laryngeal or hypopharyngeal cancer.

Abstract
OBJECTIVE Compare the results of molecular diffusion and mass flow in the interstitial space(ISS) displayed by using optical and magnetic probes and study partitioned drainage of the brain interstitial fluid (ISF). METHODS In the study, 36 male SD rats were randomly divided into fluorescent inspection group (18), magnetic tracer group (18). Then they were divided equally into caudate nucleus (Cn), thalamus (T) and substantia nigra (Sn) subgroup, 6 rats in each subgroup. Referencing the brain stereotaxic atlas, the coronal globus pallidus as center level, Cn, T or Sn were acted as puncture positioning target. A 10 μL microsyringe was stereotaxically positioned and the lucifer yellow (LY) solution of 2 μL 10 mmol/L was infused into centric position. The coronary slices undergo cardiac perfusion and fix respectively in time point Cn 3 h, T 2 h and Sn 1 h. The rat brain was placed in rat stainless steel brain matrices and cut backward along visual intersection. The injection point of coronal slice as the center level, take 3 slices in front of the center level and 2 slices behind of it. 1 mm for each slice and 6 slices in total. Then slices were detected by laser scanning confocal microscope (LSCM). Simultaneous, in the same coordinate brain regions of another three groups, a gadolinium-diethylene triamine pentaacetic acidm (Gd-DTPA) solution of 2 μL 10 mmol/L was infused into different injection and detected by MRI tracer-based method. Then the Radiant can be used to measure distribution area of Gd-DTPA. RESULTS LY and Gd-DTPA have different distribution regions in Cn, T and Sn. After LY and Gd-DTPA were introduced into the Cn subgroup 3 h, compare the 1 to 6 levels distribution area of LY and Gd-DTPA as follows: (10.95±4.27) mm2 vs. (8.33±2.25) mm2, (18.16±4.74) mm2 vs. (16.42±2.88) mm2, (24.57±3.65) mm2 vs. (20.75±2.29) mm2, (34.81±3.32) mm2 vs. (28.88±1.51) mm2, (30.53±3.12) mm2 vs. (20.92±2.75) mm2, (12.15±4.92) mm2 vs. (10.00±1.89) mm2. The statistical analysis of every level was made by T test, and the difference of the distribution area between the two tracers were not statistically significant (t=0.940, P=0.400; t=0.546, P=0.614; t=1.534, P=0.200; t=2.809, P=0.480; t=2.693, P=0.055; t=0.707, P=0.518); After LY and Gd-DTPA were introduced into the T subgroup 2 h, compare the 1-6 levels distribution area of LY and Gd-DTPA as follows: (5.56±4.61) mm2 vs. (3.33±2.25) mm2, (16.21±3.36) mm2 vs. (11.42±2.88) mm2, (19.00±5.21) mm2 vs. (15.75±2.29) mm2, (25.32±5.49) mm2 vs. (22.33±3.25) mm2, (17.34±5.31) mm2 vs. (15.92±2.75) mm2, (7.67±6.19) mm2 vs. (5.00±1.89) mm2. The statistical analysis of every level was made by T test, and the difference of the distribution area between the two tracers were not statistically significant (t=0.753, P=0.493; t=1.875, P=0.134; t=0.990, P=0.378; t=0.810, P=0.464; t=0.413, P=0.701; t=0.716, P=0.514); After LY and Gd-DTPA were introduced into the Sn subgroup 1 h, compare the 1-6 levels distribution area of LY and Gd-DTPA as follows: (6.78±4.56) mm2 vs. (4.75±2.00) mm2, (12.65±5.04) mm2 vs. (10.44±1.13) mm2, (19.51±6.54) mm2 vs. (17.55±0.30) mm2, (28.72±5.45) mm2 vs. (24.48±1.32) mm2, (21.34±4.42) mm2 vs. (17.72±0.25) mm2, (13.00±5.46) mm2 vs. (12.00±2.88) mm2. The statistical analysis of every level was made by T test and the difference of the distribution area between the two tracers were not statistically significant (t=0.705, P=0.519; t=0.743, P=0.499; t=0.517, P=0.656; t=1.310, P=0.260; t=1.416, P=0.292; t=0.281, P=0.793), but the distribution area of LY is slightly more than Gd-DTPA. CONCLUSION LSCM imaging technology confirmed partitioned drainage of the brain ISF found by MRI tracer-based method and provided technology and method validation for MRI tracer-based method. LSCM imaging technology with higher contrast and resolution, therefore more sophisticated partitioned drainage of the brain interstitial fluid were got.

Abstract
OBJECTIVE To investigate the prevalence of hypertension in ocean seamen and major influencing factors, as well as the association between hypertension and serum microRNA21 and microRNA133a. METHODS Health examination and a questionnaire survey were performed for 780 ocean seamen who underwent physical examination in an international travel healthcare center in Fujian, China from January to June, 2014. TaqMan RT-qPCR was used to measure the serum levels of microRNA21 and microRNA133a in seamen with hypertension. RESULTS The prevalence of hypertension differed significantly between the ocean seamen with different ages, education levels, marital status, body mass index (BMI) values, drinking frequencies, and numbers of sailing years (P<0.05). The prevalence rate of hypertension in the ocean seamen increased with the increasing drinking frequency (χ(2)=9.02, P<0.05) , decreased with the increase in degree of education (χ(2)=11.578, P<0.05) , and increased with the increase in the number of sailing years (χ(2)=28.06, P<0.05). The hypertensive ocean seamen had significantly higher expression levels of microRNA21 and MicroRNA133a than the healthy ocean seamen (microRNA21: 7.87±5.46 vs 1.03±0.80, P<0.05; MicroRNA133a: 7.45±1.94 vs 4.52±1.15, P<0.05). The multivariate analysis showed that a high level of microRNA21 (OR=1.61, 95% CI: 1.22~2.11) , a high level of microRNA133a (OR=1.52, 95% CI: 1.24~1.87) , drinking (OR=1.64, 95% CI: 1.08~2.50) , overweight based on BMI (OR=1.18, 95%CI: 1.07~1.30) , and many sailing years (OR=2.89, 95% CI: 1.14~7.30) were risk factors for hypertension. CONCLUSION The prevention and treatment of hypertension in ocean seamen should be enhanced. Excessive drinking should be controlled, and sailing time should be arranged reasonably. The microRNA21 and microRNA133a may be associated with the development and progression of hypertension in ocean seamen.

Factors associated with Staphylococcus aureus nasal carriage and molecular characteristics among the general population at a Medical College Campus in Guangzhou, South China. Ann Clin Microbiol Antimicrob 2017; 16:28. [PMID: 28399856 PMCID: PMC5387264 DOI: 10.1186/s12941-017-0206-0] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2017] [Accepted: 04/06/2017] [Indexed: 01/25/2023] Open
Abstract
BACKGROUND The nasal cavity is the main colonization site of Staphylococcus aureus (S. aureus) in human body. Nasal carriage may be a strong risk factor for some serious infection. There was still limited information about the nasal carriage for S. aureus in south China. METHODS Sought to determine the prevalence and molecular characteristics of S. aureus nasal carriage, 295 volunteers residing on a medicine campus were investigated and sampled the nasal cavity swab. Selected S. aureus isolates were carried through molecular analysis, including pulsed-field gel electrophoresis (PFGE), multilocus sequence analysis, staphylococcal cassette chromosome mec (SCCmec) and virulence gene detection. RESULTS A total of 73 S. aureus isolates were recovered from separate subjects (24.7%, 73/295), with one methicillin-resistant S. aureus (MRSA) isolate (0.3%, 1/295). Among the 73 isolates, 71 isolates were successfully grouped into 13 pulsotypes by PFGE analysis, with profiles A and L the most prevalent; 12 sequence types (STs) were found among the 23 isolates which had similar drug resistant spectrum. ST59, ST188 and ST1 were the most prevalent, accounting for 17.4, 13.0 and 13.0% of all isolates, respectively. The MRSA isolate presented ST8-SCCmec III. 56.5% of isolates carried both the staphylococcal enterotoxin A (sea) and enterotoxin B (seb) genes. 83.6% of the S. aureus isolates were resistant to penicillin, all isolates were susceptible to quinupristin/dalfopristin, levofloxacin, teicoplanin and vancomycin. The most common risk factors for S. aureus carriage were being male, age ≤30 years, and nasal cavity cleaning habits. CONCLUSIONS Colonization by S. aureus was greater among male and young age (20-30 years) students and those with irregularity nasal cleaning. The S. aureus isolates selected were revealed into various sequence types and pulsotypes, indicating molecular heterogeneity among S. aureus isolates from the populations in the medical college in Guangzhou.

Abstract
Sex hormone receptors play critical roles in development and reproduction. However, it is not known whether they exist in Raillietina tapeworms, and if they do, whether they have a similar function to that in vertebrates. We examined the immunohistochemical distributions of androgen receptors (ARs), estrogen receptors (ERs), and progesterone receptors (PRs) in the tissues of two tapeworm species: Raillietina echinobothrida and Raillietina tetragona. Immunopositive ARs were found in the entire reproductive system of R. echinobothrida, including the testes, ovaries, and oocysts, and weakly immunopositive ERs and PRs were found in the testes, ovaries, and oocysts. Immunopositive ARs were also found throughout the entire reproductive system of R. tetragona, including the testes, ovaries, and oocysts, and weakly immunopositive ERs were in the testes and oocysts; the PRs were distributed in an immunonegative manner. The results show that androgens and their receptors play critical roles in reproductive system development in the two tapeworms. The immunoreactivity and tissue localizations of the sex hormone receptors suggest that, in both species, they have similar functions as in vertebrates, and modulate reproduction.

Abstract
Objective: To evaluate the role of the revised International Prognostic Score of Thrombosis (IPSET-thrombosis) in predicting the occurrence of thrombotic events in Chinese patients with essential thrombocythemia (ET) and to develop a thrombosis predicting model more applicable to Chinese ET patients. Methods: Medical records of 746 adult patients with an initial diagnosis of ET were retrospectively analyzed. Results: The median age at diagnosis was 52 (18-87) years, with 305 males and 441 females. According to the revised IPSET-thrombosis model, the number of very low-, low-, intermediate-, and high-risk patients were 271 (36.3%) , 223 (29.9%) , 63 (8.4%) and 189 (25.3%) , respectively. The four groups exhibited significantly different thrombosis-free survival (χ(2)=72.301, P<0.001) . Thirty-six patients were reclassified as intermediate-risk according to the revised IPSET-thrombosis instead of low-risk as per the original IPSET-thrombosis. Nineteen intermediate-risk patients as per the original IPSET-thrombosis were upgraded to high-risk according to the revised IPSET-thrombosis. Fifty-one high-risk patients as per the original IPSET-thrombosis were reclassified as low-risk in the revised IPSET-thrombosis. It suggests that the revised IPSET-thrombosis potentially avoids over- or under-treatment. In low-risk patients as per the revised IPSET-thrombosis, the rate of thrombosis in patients with cardiovascular risk factors (CVF) was higher than that in those without (16.3% vs 5.2%, χ(2)=5.264, P=0.022) , and comparable with intermediate-risk patients as per the revised IPSET-thrombosis (16.3% vs 14.3%, χ(2)=0.089, P=0.765) . As a result, a new revised IPSET-thrombosis model more applicable to Chinese ET patients was developed in which patients with CVF in the low-risk group as per the revised IPSET-thrombosis were reclassified as intermediate-risk group. Conclusion: For predicting the occurrence of thrombotic events, the revised IPSET-thrombosis model was better than the original IPSET-thrombosis model. The revised IPSET-thrombosis was optimized and a new revised IPSET-thrombosis model more applicable to Chinese ET patients was developed, and the new evidence for risk stratification and treatment of ET in Chinese was provided.

Abstract
Objective: To investigate the management and perinatal outcome of aortic dissection during pregnancy. Methods: 24 pregnant women with aortic dissection who delivered in Beijing Anzhen Hospital Affiliated to Capital Medical University from January 1st, 2006 to February 29th, 2016 were recruited. The clinical data, the management and the perinatal outcome were analyzed retrospectively. Results: (1) Clinical features: The average age of the patients was (29±4) years old. The clinical symptoms occurred from 5 gestational weeks to 1 month after delivery. The major symptoms were chest pain, and some complained migratory or radiating pains. There were 17 Stanford type A cases and 7 type B cases. The aortic widths were 2.9-10.0 cm, with the average of (5.6±1.7) cm. D-dimer level was 448-6 421 μg/L, with the average of (1 097±1 209) μg/L, and the fibrin degradation products were 4.1-52.1 mg/L, with the average of (10.2±9.5) mg/L.The white blood cell ranged (6.8-36.4)×10(9)/L, with the average of (29.4±4.2)×10(9)/L; and the neutrophil rate was 76.0%-97.6%, with the average of (84.6±6.3) %. (2) The treatment: ①19 patients underwent aorta surgeries. The surgeries included aortic root replacement with total aortic arch replacement plus stented elephant trunk implantation (Bentall+Sun's surgery), aortic root replacement (Bentall surgery), stent implantation, thoracic and abdominal aorta replacement. The aortic operation time of the 19 patients were 5 gestational weeks to 1 month after delivery. The relation between aortic operation and the termination of pregnancy: 4 patients underwent aorta surgery after termination of pregnancy, 9 patients had cesarean section and aorta surgery at the same time, 6 patients underwent aorta surgery before cesarean section. ② 5 patients did not receive arota surgery, 2 patients of type A dissection and 1 patient of type B dissection died before the surgery; 2 cases of type B dissection underwent conservative treatment. The termination time of pregnancy was 6-37 gestational weeks, with the average of (26±10) weeks. (3)Maternal and fetal outcomes: 20 patients survived after treatment (83%, 20/24) and 4 patients died (17%, 4/24). 10 cases were live births, including 4 full-term infants and 6 preterm premature infants. The birth weight of the neonates was 1 080-3 800 g, with the average of (2 302±764) g. Three of them were very low birth weight infants and 1 was low birth weight infant; 3 neonates had mild asphyxia. The neonates were followed up for 0.5 to 10 years, with the average time of (1.4±1.7) years. So far the infants' development was good. Conclusions: Pregnancy with aortic dissection is pernicious. Early identification, prompt diagnosis and prompt interventing of the vascular surgery are necessary to the safety of mother and fetus.

Abstract
OBJECTIVE To evaluate the survival outcomes of invasive fungal rhinosinusitis by analyzing the clinical features. METHODS A retrospective analysis was performed for cases of invasive fungal sinusitis proved by histological analysis between March 2006 and November 2015. All relevant factors including interval from the onset of symptoms to initiation of diagnosis, clinical characteristics, features of CT and MRI, treatment and prognosis were collected. A total of 18 patients (10 males; 8 females) were identified. The median age was 54 years old. Three patients suffered from acute invasive fungal sinusitis, while the other 15 suffered from chronic invasive fungal sinusitis. RESULTS The mean duration between onset of symptoms and diagnosis was 5 months. The most common symptom was headache (10/18), followed by visual disturbance (7/18), nasal obstruction (4/18), facial numbness and pain (2/18) and diplopia(2/18). Two patients had diabetes mellitus; one patient had ankylosing spondylitis receiving immunosuppressive drugs treatment for one year. Four patients had the disease confined in the sinus. Complications of this disease included orbital apex involvement in 6 patients, intraorbital and optic nerve involvement in 3 patients, cavernous sinus involvement in 5 patients, pterygopalatine fossa and infratemporal fossa involvement in 5 patients, intracranial extension involvement in 3 patients. Fungal species included aspergillus (15 cases) and mucor (3 cases). Seventeen patients received intravenous antifungal therapy after surgery. The duration of follow-up ranged from 1 to 60 months. Two patients reoccurred and one patient died of the disease. CONCLUSION Endoscopic debridement combined with intravenous antifungals is efficacious in the management of invasive fungal sinusitis.

Abstract
Objective: To analyze the correlation between retinal vascular calibers, ocular blood flow parameters and internal carotid artery stenosis and to evaluate the effect of internal carotid artery stenosis on ocular blood vessels comprehensively. Methods: A retrospective case-control study. The clinical data of 141 patients who underwent head-and-neck computed tomography (CT) angiography examinations of the ICA were collected at Beijing Friendship Hospital, Capital Medical University from January 2014 to January 2016. According to diagnostic criteria, the patients were divided into four groups: the non-stenosis group, the mild stenosis group, the moderate stenosis group, and the severe stenosis andocclusion group. The retinal vascular caliber was measured in color fundus photograph by IVAN software. Color Doppler ultrasonography was used to measure the parameters of ocular blood flow, including the peak systolic velocity (PSV), end diastolic velocity (EDV), resistance index (RI) and pulsatility index (PI). The enumeration data were analyzed with chi-square test, the measurement data were analyzed with rank-sum test, and the correlation test was performed with spearman. Results: The gender ratio of the patients without stenosis, mild stenosis, moderate stenosis, severe stenosis and occlusion was 12/7, 31/19, 28/25, 12/7, χ2 test was not statistically significant (χ2= 0.79, P=0.85); There was no statistically significant difference between the different groups (χ2= 0.15, P=0.68), the age of four groups were (64.1±8.3), (54.3±14.3), (68.9±11.8) and (59.1±8.0) y, respectively. In the no internal carotid artery stenosis group, the arteries diameter is (164.5±15.6) μm ,the vein diameter is (245.6±20.0) μm and the arteriovenous ratio is 0.7±0.1. There is no difference among the mild stenosis group, moderate stenosis group and the severe stenosis (χ2artery caliber=6.92, Partery caliber=0.08; χ2vein diameter=4.16, Pvein diameter=0.25; χ2arteriolar-venular ratio=1.38,Parteriolar-venular ratio=0.71) . The PSV of central retinal artery in the above groups were (14.6±3.6), (34.4±13.2), (35.7±14.6), (42.3±19.0)cm/s respectively, the data were analyzed by rank-sum test and there was a significant difference (χ2=13.44, P< 0.01) ; The PSV of the posterior ciliary artery in the above groups (17.6±6.5), (15.0±4.6), (13.4±4.3) and (11.0±3.2)cm/s respectively, the data were analyzed by rank-sum test and there was a significant difference (χ2=22.71, P<0.01) , EDV were (5.90±2.2), (5.1±2.1), (4.3±1.5) and (4.3±4.8)cm/s respectively and there was a significant difference (χ2=20.36, P<0.01) .There was a correlation between retinal artery diameter, PSV and EDV of the central retinal artery, PSV and EDV of the posterior ciliary artery and the diameter of the internal carotid artery but without linear correlation. (rartery caliber=-0.23, Partery caliber=0.01; rPSV of central retinal artery= -0.29, PPSV of central retinal artery<0.01; rPSV of posteri or ciliary artery=-0.34, PPSV of posterior ciliary artery<0.01, rEDV of posterior ciliary artery=-0.35, PEDV of posterior ciliary artery<0.01). Conclusions: There was a correlation between retinal artery diameter, PSV and EDV of the central retinal artery, PSV and EDV of the posterior ciliary artery and the diameter of the internal carotid artery. PSV of the central retinal artery, PSV and EDV of the posterior ciliary artery changed significantly when the internal carotid artery stenosis existed. (Chin J Ophthalmol, 2016, 52: 905-910).

Abstract
Objective: To study the characteristics of neurosyphilis with optic neuritis as an initial finding. Methods: Retrospective analysis of clinical data and laboratory testing results of 16 cases (27 eyes) with optic neuritis as an initial finding of neurosyphilis from October 2010 to March 2015 in General Hospital of People's Liberation Army was made. Results: Six-teen patients (12 males, 4 females) were collected, the median age of patients was 47 (range 33 to 65) years ,the mean age was (49.63±9.05) years. Treponema pallidum particle agglutination assay (TPPA) analysis was positive in all of the patients and rapid plasma reagin (RPR) test was positive in 14 patients (2 patients did not test). Lumbar puncture was requested and performed for all patients. Cerebrospinal fluid (CSF) TPPA analysis was positive in 16 patients and RPR test was positive in 12 patients. The CSF white blood cell counting increased in 9 (56.3%) patients and 10(62.5%)patients presented with increased CSF protein level. Both eyes were involved in 11 patients (68.8%). Relative afferent papillary defect was positive in 11 patients. Twenty-seven eyes were affected in 16 patients, and among them 7 eyes' pupil diameter were 2.5 mm or less. Incipient visual acuity was less than 0.1 in 22 eyes. The slit lamp examination showed vitreous opacity in 12 eyes and visible cells in 6 eyes among 27 eyes. Fundus examination found that 6 eyes had papillary edema and 15 eyes had pallordisc among 27eyes. Electro-retinogram (ERG) was tested in 24 eyes, and 18 eyes were abnormal. Visual evoked potential (VEP) were performed in 26 eyes (flash VEP in 22 eyes, pattern VEP in 4 eyes), and all were abnormal. Fourteen eyes were tested by 30-2 perimetry, and 6 eyes had diffuse visual field defect, 2 eyes had peripheral visual field defect, 4 eyes had quadrant defect and 2 eyes had center scotoma. Fundus fluorescence angiography was done in 16 eyes and choroidal hyper-fluorescent dots were found in posterior pole in 4 eyes. All patients were treated with antibiotic medicines, among them 10 cases in the General Hospital, and 6 cases in the other hospitals. During 15 months follow-up after discharge, visual acuity of 17 eyes recovered to 0.5 and above. Conclusion: Syphilitic optic neuritis is a condition that manifests with severe visual loss and tends to involve both eyes, Some patients have a smaller pupil diameter. Due to the particular infective routes of the disease, patients often conceal their sexual history. The manifestations of ocular syphilis are complicated and easy to misdiagnose or undiagnose. Clinical manifestations combining with the detailed history taking, serum and cerebrospinal fluid examination can guide to an accurate diagnosis and prevent from permanent vision loss.

Abstract
Objective:To further explore the prognostic effects of Heparanase(HPA) and NF-E2 related factor (NRF2) on smoking related laryngeal squamous cell carcinoma,we detect the expression of HPA and NRF2 on smoking related laryngeal squamous cell carcinoma patients.Method:Continuously collected 84 patients with laryngeal squamous cell carcinoma in the Ningde Hospital from 2014 to 2015.All patients were divided into three groups according to smoking index:group A (severe smoking patients with laryngeal carcinoma 30 cases),group B(mild to moderate smokers 20 cases) and group C (no smoking in laryngeal carcinoma patients with 34 cases).Antioxidative indices in serum and the expression of HPA and NRF2 in three groups of patients were detected, and to explore their relationship with prognosis and clinical staging of patients.Result:The HPA and NRF2 were highly expressed in the cancer tissues of patients with stage Ⅲ-Ⅳ,while the expression of HPA and NRF2 in patients with stage Ⅰ-Ⅱ was low. The expression level of NRF2 in group A was significantly higher than that of group Band group C(P <0.05) as well as the NRF2 expression levels in higher stage patients with laryngeal cancer were higher than those of low stages.The expression of HPA and NRF2 is related to the pathological stage in laryngeal squamous cell carcinoma patients(P <0.05).Conclusion:Compared with non smoking patients, severe smoking patients with laryngeal cancer will face more severe oxidative stress. The expression of HPA and NRF2 in laryngeal squamous cell carcinoma patients is related to the pathological stage.

Abstract
OBJECTIVE To investigate the causes and strategies for intraoperative rupture during clipping the anterior circulation aneurysms. METHODS Nineteen patients with anterior circulation aneurysms ruptured during clipping, who admitted to the Department of Neurosurgery, Henan Provincial People's Hospital from November 2012 to February 2014, were enrolled. Their clinical data were analyzed retrospectively to summarize the causes and strategies for intraoperative rupture. RESULTS The aneurysms ruptured during predissection in 2 cases (10.5%), during dissection in 11 cases (57.9%) and during clip application in 6 cases (31.6%). There was no residual aneurysm confirmed by postoperative CTA in 17 patients. One case with posterior communicating artery aneurysm cannot be clipped because of the serious avulsion of the aneurysm neck during clipping. The aneurysm was trapped and the patient paralysed on one side after operation. One case died postoperative 8 days because of severe cerebral edema, whose aneurysm ruptured during predissection. The Glasgow Outcome Scale (GOS) of three months after operation showed good recovery in 11, moderate recovery in 5, severe disability in 2, and death in 1 cases, respectively. CONCLUSION Adequate preoperative evaluation for the risk factors of intraoperative rupture and excellent microsurgical techniques can prevent intraoperative rupture of intracranial aneurysms. Controlling the bleeding quickly and dissecting and clipping the aneurysm after definitely know the anatomy of the aneurysm and surrounding vasculature could be the keys to deal with intraoperative aneurysm rupture.

Abstract
Glycine betaine is an important quaternary ammonium compound that is produced in response to several abiotic stresses in many organisms. The synthesis of glycine betaine requires the catalysis of betaine aldehyde dehydrogenase (BADH), which can convert betaine aldehyde into glycine betaine in plants, especially in halotolerant plants. In this study, we isolated the full-length cDNA of BADH from Suaeda corniculata (ScBADH) using reverse transcriptase-polymerase chain reaction and rapid amplification of cDNA ends. Next, we analyzed the expression profile of ScBADH using real-time PCR. The results showed that ScBADH expression was induced in the roots, stems, and leaves of S. corniculata seedlings under salt and drought stress. Next, ScBADH was overexpressed in Arabidopsis, resulting in the transgenic plants exhibiting enhanced tolerance over wild-type plants under salt and drought stress. We then analyzed the levels of glycine betaine and proline, as well as superoxide dismutase (SOD) activity, during salt stress in WT and transgenic Arabidopsis. The results indicated that overexpression of ScBADH produced more glycine betaine and proline, and increased SOD activity under NaCl treatment. Our results suggest that ScBADH might be a positive regulator in plants during the response to NaCl.

Abstract
The aim of this study was to investigate the association between a functional variant of the basigin (BSG) gene, caused by a polymorphism (rs11473) at the miR-483-5p binding site, and the risk of esophageal squamous cell carcinoma (ESCC) in the Chinese population. The rs11473 polymorphism was genotyped in 624 esophageal cancer patients and 636 cancer-free age- and gender-matched controls using polymerase chain reaction restriction and direct sequencing. The functional variants resulting from the BSG rs11473 SNP were investigated using a luciferase activity assay and validated by immunoblotting. We discovered that ESCC patients carrying the rs11473 AA genotype or A allele were at a significantly higher risk of esophageal cancer [odds ratio (OR) = 1.560, 95% confidence interval (CI) = 1.031-2.358, P = 0.037; OR = 1.231, 95%CI = 1.038-1.459, P = 0.017, respectively] than those carrying the GG genotype and G allele. Moreover, the rs11473 polymorphism modifies the binding of miR-483- 5p to basigin, as well as the basigin protein levels in esophageal cancer patients. Our data suggested that the rs11473 polymorphism at the miR- 483-5p binding site in the 3'-UTR of basigin gene may play a key role in the development of esophageal cancer in a Chinese population.
