By combining the distributed Kalman filter (DKF) with the back propagation neural network (BPNN),a novel method is proposed to identify the bias of electrostatic suspended gyroscope (ESG). Firstly,the data sets of multi-measurements of the same ESG in different noise environments are "mapped" into a sensor network,and DKF with embedded consensus filters is then used to preprocess the data sets. After transforming the preprocessed results into the trained input and the desired output of neural network,BPNN with the learning rate and the momentum term is further utilized to identify the ESG bias. As demonstrated in the experiment,the proposed approach is effective for the model identification of the ESG bias. 展开更多

The estrogen receptor β (ESR2) gene is a candidate mediating the genetic influence on bone mass and the risk of osteoporosis. The aim of this study is to investigate the association of a cytosine-adenine (CA) repeat polymorphism in the fifth intron of the ESR2 gene with PMO in Chinese Han population. The CA repeat polymorphism was genotyped in a case-control study, involving 78 femoral neck PMO patients vs. 122 controls and 108 lumbar spine (L2-4) PMO patients vs. 92 controls. The (CA)n〈22 and (CA)n≥22 alleles were designated short (S) and long (L), respectively. ESR2 genotype was categorically defined as SS (2 S alleles), SL (having the mixed S and L alleles), and LL (2 L alleles). At both the femoral neck and the L2-4 region, LL genotype and L allele frequencies of the PMO group were significantly higher than those of the control group (P〈0.01). The subjects with the SL, the LL, and the combined SL and LL genotype had a significant increased risk of PMO when compared with those with the SS genotype (P〈0.05). After adjustments for age, years since menopause, menopausal age, and body mass index, logistic regression analysis showed that the subjects with the combined SL and LL genotype had increased risk of PMO when compared with those with the SS genotype both at the femoral neck (adjusted OR 4.923, 95% CI 1.986-12.203 , P=0.001) and the L2-4 (adjusted OR 2.267, 95% CI 1.121-4.598, P=0.023). This extensive association study has identified the ESR2 CA repeat polymorphism to be independently associated with PMO at the femoral neck and the L2-4 in Chinese Han population. The data also suggested that the presence of the L allele may dominantly increase the risk of PMO at the two regions. 展开更多

Objective: To observe the relationship between non-small cell lung cancer with neuroendrocrine differentiation (NSCLC-NE) and patients' postoperative survival. Methods: During April 1997 to April 1999, 98 cases of hlng cancer were surgically treated. The tumor specimens of the patients were stained by NE markers, i.e. neuron specific enolase (NSE) and synaptophysin (SY). The intensity of NE markers reaction was divided as "+". "++". "+++" scale groups. The same specimens were also examined under an electron microscope for the specific neuroendocrine granules. All enrolled patients were followed up for 36 months, and the longest follow-up time was 60 months. The COX proportional hazard model multivariate analysis was applied to observe the relationship between the NSCLE-NE and the patients' postoperative survival. Results: In 91 cases of NSCLC, 63.7% (58/91) were positive for NE stain reaction. Among them, 59.3% (54/91) were positive for NSE and 24.1% (22/91) for SY. 48.4% (44/91) were considered as NSCLC-NE by the combination of NE inarker stain reaction and electron microscopic examination. COX proportional hazard model lnnltivariate analysis showed that the NSCLC-NE patients' survival was significantly shortened (P=0.048). The following factors were related to NSCLC-NE patients' survival: lung cancer cell differentiation (P=0.006), clinical lung cancer stage (P=0.001), the NE markers reaction (P=0.054). Conclusion: NSCLE-NE is significantly related to the cancer cell differentiation and the patients' postoperative survival. The NE markers should be applied clinically as one of prognostic factors to evaluate the postoperative survival of NSCLC patients. 展开更多

In 2010, China entered the advanced stage of industrialization, which coincided with the country's entry into a new stage of economic growth. However, this transition is associated with major risks, including adapting to decelerating economic growth. While recognizing the move toward a service-based economy, China must seek to prevent the risk of "manufacturing hollowing out. "' It must also avoid the "technology upgrade trap" while taking advantage of increasingly sophisticated industrial structures. Efforts must also be made to: (1) promote the integration of lT tools and meet risks arising from the New Industrial Revolution; (2) resolve liability risks arising from capacity reduction; and (3) expedite the transition to a functional industrial policy and prevent the failure of a functional industrial policy. In climbing up the global value chain, China must confront the competitive pressures from advanced and emerging economies on both high- and low-end processes of the global value chain. 展开更多

Objective To investigate the changes of neural stem cells (NSCs) in the rat hippocampus after cerebral infarction (CI) and to evaluate the neurogenesis caused by the activation of NSCs. Methods CI models of rats were made and rats were assigned to 6 groups: sham-operated, 1 day, 3 days, 7 days, 14 days, and 28 days after CI. The dynamic expression of bromodeoxyuridine (BrdU), polysialylated neural cell adhesion molecule (PSA-NCAM), glial fibrillary acidic protein (GFAP), and neuronal nuclear antigen (NeuN) were determined by immunohistochemistry and immunofluorescence staining. BrdU was used to mark the proliferated NSCs. PSA-NCAM was used to mark the plasticity of activated NSCs. GFAP and NeuN were used to mark the differentiated NSCs. Results Compared with the controls, the number of BrdU+ cells in the hippocampus increased significantly at 1 day after CI (P<0.05), reached peak at 7 days after CI (P<0.05), decreased but still elevated compared with the controls at 14 days after CI (P<0.05), and nearly unchanged at 28 days after CI. The number of BrdU+/PSA-NCAM+ cells increased significantly at 7 days after CI (P<0.05), reached peak at 14 days after CI (P<0.05), and decreased but still elevated compared with the controls at 28 days after CI (P<0.05). The number of BrdU+/PSA-NCAM+ cells was equal to 60% of the number of BrdU+ cells in all the same period. The number of BrdU+/NeuN+ cells in the hippocampus increased significantly at 14 days after CI (P<0.05) and reached peak at 28 day after CI (P<0.05). The number of BrdU+/GFAP+cells in the hippocampus nearly unchanged after CI. Conclusion CI can stimulate the proliferation of inherent NSCs, and most proliferated NSCs may differentiate into neurons and represent neural plasticity. 展开更多

Objectives To address whether menopause affects outcome of catheter ablation (CA) for atrial fibrillation (AF) by comparing the safety and long-term outcome of a single-procedure in pre-and post-menopausal women. Methods A total of 743 female patients who underwent a single CA procedure of drug-refractory AF were retrospectively analyzed. The differences in clinical presentation and outcomes of CA for AF between the pre-menopausal women (PreM group, 94 patients, 12.7%) and the post-menopausal women (PostM group, 649 patients, 87.3%) were assessed. Results The patients in the PreM group were younger (P&lt;0.001) and less likely to have hypertension (P&lt;0.001) and diabetes (P=0.005) than those in the PostM group. The two groups were similar with regards to the proportion of concomitant mitral valve regurgitation coronary artery disease, left atrium dimensions, and left ventricular ejection fraction. The overall rate of complica-tions related to AF ablation was similar in both groups (P=0.385). After 43 (16-108) months of follow-up, the success rate of ablation was 54.3%in the PreM group and 54.2%in the PostM group (P=0.842). The overall freedom from atrial tachyarrhythmia recurrence was simi-lar in both groups. Menopause was not found to be an independent predictive factor of the recurrence of atrial tachyarrhythmia. Conclusions The long-term outcomes of single-procedure CA for AF are similar in pre-and post-menopausal women. Results indicated that CA of AF appears to be as safe and effective in pre-menopausal women as in post-menopausal women. 展开更多

AIM: To clarify the relationship between age, menopause, and nonalcoholic fatty liver disease (NAFLD) in women. METHODS: We conducted a follow-up study on non-alcoholic fatty liver disease by using abdominal ultrasonography, and investigated the relationship of age and menopause with the development of NAFLD in women. We followed 1829 women and 2572 men (response rate, 86%) selected in 2001 to represent the non-institutionalized adult population of Gifu, Japan. Data collected included self-reported medical history, lifestyle factors, and menopausal status. The postmenopausal state was defined as beginning 1 year after the cessation of menses. We diagnosed NAFLD with the aid of abdominal ultrasonography by using diagnostic criteria describedRESULTS: The prevalence of NAFLD in women increases with age, but does not alter with age in men. Furthermore, the prevalence of NAFLD in premenopausal women (6%) was lower than that in men (24%) and in postmenopausal women (15%). The associations of the postmenopausal state and hormone replacement therapy with NAFLD were statistically significant in a univariate logistic regression model. At the follow-up examination, 67 women (5%) were newly diagnosed with NAFLD. The incidence of NAFLD was 3.5% (28/802) in premenopausal women, 7.5% (4/53) in menopausal women, 6.1% (24/392) in postmenopausal women, and 5.3% (11/206) in women receiving hormone replacement therapy. The weight gain in premenopausal women was equal to that in postmenopausal women. Metabolic syndrome and weight gain were independent risk factors for NAFLD in pre-and postmenopausal women, but age was an independent risk factor in premenopausal women only. CONCLUSION: Aging is a risk factor for NAFLD in premenopausal women, independent of weight gain or influence of metabolic syndrome. 展开更多

We report a case of a patient presenting with clinical,radiological and endoscopic features of colitis due to a compressive left para-aortic mass. Total open surgical excision was performed,which resulted in complete resolution of colitis. Histopathology and immunohistochemistry revealed benign retroperitoneal schwannoma. These neural sheath tumors rarely occur in the retroperitoneum. They are usually asymptomatic but as they enlarge they may compress adjacent structures,which leads to a wide spectrum of non-specific symptoms,including lumbar pain,headache,secondary hypertension,abdominal pain and renal colicky pain. CT and MR findings show characteristic features,but none are specific. Schwannoma can be isolated sporadic lesions,or associated with schwannomatosis or neurofibromatosis type Ⅱ (NF2). Although they vary in biological and clinical behavior,their presence is,in nearly every case,due to alterations or absence of the NF2 gene,which is involved in the growth regulation of Schwann cells. Both conditions were excluded by thorough mutation analysis. Diagnosis is based on histopathological examination and immunohistochemistry. Total excision is therapeutic and has a good prognosis. Schwannomatosis and NF2 should be excluded through clinical diagnostic criteria. Genetic testing of NF2 is probably not justified in the presence of a solitary retroperitoneal schwannoma. 展开更多

AIM: To clarify the innervation of human gallbladder,with special reference to morphological understanding of gallstone formation after gastrectomy.METHODS: The liver, gallbladder and surrounding structures were immersed in a 10 mg/L solution of alizarin red S in ethanol to stain the peripheral nerves in cadavers (n = 10). Innervation in the areas was completely dissected under a binocular microscope. Similarly,innervation in the same areas of 10 Suncus murinus (S. murinus) was examined employing whole mount immunohistochemistry.RESULTS: Innervation of the gallbladder occurred predominantly through two routes. One was from the anterior hepatic plexus, the innervation occurred along the cystic arteries and duct. Invariably this route passed through the hepatoduodenal ligament. The other route was from the posterior hepatic plexus, the innervation occurred along the cystic duct ventrally. This route also passed through the hepatoduodenal ligament dorsally.Similar results were obtained in S. murinus.CONCLUSION: The route from the anterior hepatic plexus via the cystic artery and/or duct is crucial for preserving gallbladder innervation. Lymph node dissection specifically in the hepatoduodenal ligament may affect the incidence of gallstones after gastrectomy.Furthermore, the route from the posterior hepatic plexus via the common bile duct and the cystic duct to the gallbladder should not be disregarded. Preservation of the plexus may attenuate the incidence of gallstone formation after gastrectomy. 展开更多

The most promising approach for studying soil moisture is the assimilation of observation data and computational modeling. However, there is much uncertainty in the assimilation process, which affects the assimilation results. This research developed a one-dimensional soil moisture assimilation scheme based on the Ensemble Kalman Filter (EnKF) and Genetic Algorithm (GA). A two-dimensional hydrologic model-Distributed Hydrology-Soil-Vegetation Model (DHSVM) was coupled with a semi-empirical backscattering model (Oh). The Advanced Synthetic Aperture Radar (ASAR) data were assimilated with this coupled model and the field observation data were used to validate this scheme in the soil moisture assimilation experiment. In order to improve the assimilation results, a cost function was set up based on the distance between the simulated backscattering coefficient from the coupled model and the observed backscattering coefficient from ASAR. The EnKF and GA were used to re-initialize and re-parameterize the simulation process, respectively. The assimilation results were compared with the free-run simulations from hydrologic model and the field observation data. The results obtained indicate that this assimilation scheme is practical and it can improve the accuracy of soil moisture estimation significantly. 展开更多

The System Resource Constraint Theory intends to research growth of economy under different classes of system resource constraint. By analogy between ecology system and economic system, from the angle of total nature resource, total supply ability and total market volume, the theory focuses on the constraint condition and development characteristic of economy as well as the various game characteristics among economies such as independence, competition, and joint competition. According to the math deduction, the author finds that Logistic model is relative with Marthus's model and Zero-growth model. 展开更多

Primary osteoporosis, a commonly encountered metabolic bone disease in the postmenopausal women and the aged people, can be classified by modern medicine into postmenopausal osteoporosis (Type I) and senile osteoporosis (Type II). The disease seriously affects health and quality of life of the people as it often cause ostealgia, fracture and the secondary symptoms or diseases. Presently, the pharmacotherapy (including both Chinese herbal drugs and western drugs) remains the first among all other therapeutic methods which are mainly adopted in treatment of the disease at home and abroad. Studies related have been curried out quite early and systematically, and considerable progress has been made, but limit of the pharmacotherapy has also been found. Certain non-drug treatments (such as dietetic therapy, physical exercise, acupuncture and moxibustion, and qigong, especially acupuncture and moxibustion therapy, although with a late start, have been proved effective with satisfactory results.

This paper takes into consideration the doctrinal positions that are taken by Italian accounting in the period between the 19th and the 20th century, and concerns the nature of relationships between accounting and its most similar sciences, particularly economics. Over those years, the scholars in that field started to show a peculiar epistemological sensitivity. Spurred by the philosophical debate which was raised by positivism and particularly by Comte's and Spencer's studies, researchers wondered whether the most appropriate place for accounting was in the large field of social sciences. Hence, two different epistemological approaches arose with one succeeding the other in time. Initially, scholars accepted the idea that accounting somehow depended on its related sciences, which included economics. They deemed it convenient to use, also for their own purposes, principles drawn from contiguous doctrines that had already been scientifically recognized, such as economics. That was how Italian accounting happened to be, even though temporarily, in a position of "scientific subjection" with respect to the mentioned doctrines. At the second stage, due to the awareness of the specific subject and the method of investigation, as well as the purposes, Italian accounting claimed its own scientific autonomy, so scholars went back to the first phase and considered it necessary to develop internal principles and rules as a function of its peculiar needs. By doing so, scholars mapped out a route that would deeply mark the future of the discipline by making it fully independent on other fields of knowledge in a sort of emancipation process. The paper will not only describe the two theoretical positions which are summarized above, but will also adopt an interpretative approach to trace their possible causes and to grasp their effects on the development of the discipline, particularly with regards to the theories of value which is adopted by the Italian accounting over the analyzed period. In the authors' opinion, the attention paid by the most authoritative Italian accounting scholars to the epistemological theme of relationships between accounting and its similar sciences can be explained by at least two different causes: the influence which is exercised by the philosophical studies and the aspiration of accounting for scientific and academic recognition. 展开更多

Objective: Postmenopausal women with breast cancer are at increased risk of bone loss because of age related estrogen deficiency face which accelerated with the use of aromatase inhibitors (AIs). We aimed to study the effect on bone mineral density (BMD) and bone formation biomarker osteocalcin level in postmenopausal breast cancer patients, for the first three years of adjuvant hormonal treatment of both groups Tamoxifen versus Anastrozol. Methods: One-hundered postmenopausal breast cancers were prospectively randomized to receive either Tamoxifen 20 rag/day (n = 50) or Anastrozole 10 mg (n = 50). Both BMD and osteocalcin were assessed initially before treatment and then at regular intervals for both groups. Results: Use of Tamoxifen was associated with significant annual decrease in osteocalcin (P = 0.001), whereas Anastrozole group had gradual increase of the annual levels (P 〈 0.01). BMD decreased significantly in Anastrozole versus Tamoxifen groups (2.6% vs. 0.4%, P 〈 0.001). Osteoporosis T 〈 -2.5 was reported significantly higher in Anastrozole group (P 〈 0.01). Women with initial osteopenia in Anastrozole group showed significant decrease in BMD (P 〈 0.05). The addition of bisphosphonate for patients with early osteoporosis markedly improved both osteocalcin level and BMD. Conclusion: Tamoxifen preserves BMD in postmenopausal breast cancer patients, whereas Anastrozole accelerates age associated fall in BMD especially in the first year of therapy, moreover, the addition of bisphosphonate can help to decrease the skeletal related events associated with treatment to ensure better quality of life with treatment. 展开更多

Worldwide, large studies have shown that the menopause is mainly associated with substantial changes in body composition that result in an increase in waist circumference, fat accumulation and specially weight gain. This overweight could be exacerbated by fat intake. Thus, this study was planned to evaluate the impact of the consumption of olive and argane oils on anthropometric profile and body composition of postmenopausal women. The nutritional intervention was conducted over a period of eight weeks, involving daily consumption of 25 mL of argane oil The anthropometric profile (weight, height and body mass index or olive oil in 151 postmenopausal women (55.49 ± 6.18 years old). (BMI)) and body composition (fat mass (FM) and lean mass (LM)) were determined at 0 week (baseline), and after the 4th and 8th weeks of nutritional intervention. Results clearly demonstrated that argane oil or olive oil consumption did not affect the anthropometric parameters and the body composition of postmenopausal women. Thus, argane and/or olive oils' regular diet does not lead to weight gain, and postmenopausal women could benefit from their impact on health for a better quality of life and to overcome all menopause associated problems. A longer period of nutritional intervention is required to confirm the trend down that was recorded. 展开更多
