A weakly nonlinear oscillator was modeled by a sort of differential equation, a saddle-node bifurcation was found in case of primary and secondary resonance. To control the jumping phenomena and the unstable region of the nonlinear oscillator, feedback controllers were designed. Bifurcation control equations were obtained by using the multiple scales method. And through the numerical analysis, good controller could be obtained by changing the feedback control gain. Then a feasible way of further research of saddle-node bifurcation was provided. Finally, an example shows that the feedback control method applied to the hanging bridge system of gas turbine is doable. 展开更多

Primary and secondary hyperoxaluria are two distinct clinical expressions of hyperoxaluria. Primary hyperoxaluria is an inherited error of metabolismdue to defective enzyme activity. In contrast, secondary hyperoxaluria is caused by increased dietary ingestion of oxalate, precursors of oxalate or alteration in intestinal microfora. The disease spectrum extends from recurrent kidney stones, nephrocalcinosis and urinary tract infections to chronic kidney disease and end stage renal disease. When calcium oxalate burden exceeds the renal excretory ability, calcium oxalate starts to deposit in various organ systems in a process called systemic oxalosis. Increased urinary oxalate levels help to make the diagnosis while plasma oxalate levels are likely to be more accurate when patients develop chronic kidney disease. Defnitivediagnosis of primary hyperoxaluria is achieved by genetic studies and if genetic studies prove inconclusive, liver biopsy is undertaken to establish diagnosis. Diagnostic clues pointing towards secondary hyperoxaluria are a supportive dietary history and tests to detect increased intestinal absorption of oxalate. Conservative treatment for both types of hyperoxaluria includes vigorous hydration and crystallization inhibitors to decrease calcium oxalate precipitation. Pyridoxine is also found to be helpful in approximately 30% patients with primary hyperoxaluriatype 1. Liver-kidney and isolated kidney transplantation are the treatment of choice in primary hyperoxaluria type 1 and type 2 respectively. Data is scarce on role of transplantation in primary hyperoxaluria type 3 where there are no reports of end stage renal disease so far. There are ongoing investigations into newer modalities of diagnosis and treatment of hyperoxaluria. Clinical differentiation between primary and secondary hyperoxaluria and further between the types of primary hyperoxaluria is very important because of implications in treatment and diagnosis. Hyperoxaluriacontinues to be a challenging disease and a high index of clinical suspicion is often the first step on the path to accurate diagnosis and management. 展开更多

This disorder can present as hepatic mass or mass-like lesion. Chemotherapy often is the first line treatment for patients with HL. Thus, an accurate pre-management histological diagnosis is essential to potentially improve clinical outcomes. The present study was to explore the prevalence of HL in ultrasound guided liver biopsies for hepatic mass or mass-like lesions, to investigate HL associated clinicopathological features, to raise the awareness of early recognition and proper diagnosis of this entity, and to assess specimen adequacy in needle core biopsy. METHODS: Twenty-one cases of HL were enrolled. Clinical and pathological characteristics were evaluated, quality of biopsies was assessed and pertinent literature was reviewed. RESULTS: HL was diagnosed in 0.94% of 2242 liver biopsy cases with ambiguous clinical presentation, laboratory tests and image studies. There were two cases of PHL (0.09%), and nineteen cases of SHL (0.85%). Histopathologically, diffuse large B-cell lymphoma was the most common type, followed by B-cell lymphoma not otherwise specified, T-ceU lymphoma, Hodgkin's lymphoma, and B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma. Additionally, three lym- phocytic infiltration patterns were documented microscopically. The nodular infiltration was the most common type. CONCLUSIONS: HL is a rare entity and histopathology along with ancillary tests remains the only way to make the diagnosis.Clinicians' awareness of this entity and early liver biopsy are essential in patient management. 展开更多

Although the observed progress in the cardiovascular disease treatment, the incidence of new and recurrent coronary artery disease remains elevated and constitutes the leading cause of death in the developed countries. Three-quarters of deaths due to cardiovascular diseases could be prevented with adequate changes in lifestyle, including increased daily physical activity. New evidence confirms that there is an inverse dose-response relationship between physical activity and cardiovascular disease and mortality risk. However, participation in moderate to vigorous physical activity may not fully attenuate the independent effect of sedentary activities on increased risk for cardiovascular diseases. Physical activity also plays an important role in secondary prevention of cardiovascular diseases by reducing the impact of the disease, slowing its progress and preventing recurrence. Nonetheless, most of eligible cardiovascular patients still do not benefit from secondary prevention/cardiac rehabilitation programs. The present review draws attention to the importance of physical activity in the primary and secondary prevention of cardiovascular diseases. It also addresses the mechanisms by which physical activity and regular exercise can improve cardiovascular health and reduce the burden of the disease. 展开更多

To explore the impact of teacher training on the professional identity of primary and secondary school mental health teachers, this study conducted a half-month professional development training program to 54 primary and secondary school mental health teachers, and performed measurement on the professional identity of the teachers in the experimental group and the control group with “Teachers’ Professional Identity Questionnaire”. The result shows that after the training there is a significant improvement in the professional identity of the teachers in the experimental group, and the teachers’ scores on the four dimensions of profession identity: the sense of role, the professional behavioral tendency, the occupational values, and the sense of belonging, all increased significantly. This indicates that the curriculum intervention for the primary and secondary school mental health teachers could effectively improve the teachers’ professional identity. 展开更多

BACKGROUND Synovial sarcoma(SS)accounting for 6%-10%of primary soft tissue malignancies mainly occurs in deep soft tissue adjacent to joints of the limbs.Primary pulmonary SS(PPSS)is rare and has a poor prognosis.Cases of secondary distant metastases of PPSS occur rarely and there is a lack of corresponding imaging reports.We summarized the imaging findings of PPSS with multiple metastases confirmed by surgery and pathology,and shared valuable information on PPSS.CASE SUMMARY A 43-year-old female patient had a solid space occupying lesion in the right upper lobe of the lung.The results of a hemogram,erythrocyte sedimentation rate(ESR)and tumor markers were all within the normal range,tuberculin skin test(5 TU PPD)was negative(-).Chest computed tomography examination showed similar round soft tissue density in the posterior segment of the right upper lobe.Thoracoscopic-assisted wedge resection of the right upper lobe of the lung,right upper lobe resection and lymph node dissection were performed.Nine months after surgery,ultrasound examination showed multiple metastases on the chest wall and kidney.CONCLUSION PPSS is a rare malignant lung tumor with strong invasiveness,early distant metastasis and poor prognosis.There are very few imaging reports.PPSS is often manifested as irregular tumor and calcification,and the metastases have extremely low echo on ultrasonography.Contrast-enhanced ultrasound indicates that the arterial phase of tumor metastases shows rapid centripetal high enhancement,manifested as“fast forward and fast regression”. 展开更多

Purpose: Accurate identification of carcinoma of unknown primary site (CUP) patients with colorectal sites of origin may improve outcomes by directing colorectal chemotherapy rather than empiric chemotherapy. Clinical features, standard pathologic evaluation, treatment response, and survival of CUP patients whose tumors had colorectal genetic signatures were examined. Patients and Methods: We prospectively tested paraffin-embedded biopsies from 213 CUP patients using mRNA-based RT-PCR assays, and identified patients with colorectal genetic signatures. Results: Assays were successful in 185 specimens (87%);32 (17%) had colorectal genetic signatures. All 32 patients had carcinoma;colonoscopy was normal in 30 patients studied;29 patients (90%) had typical metastatic sites;17 (53%) had consistent IHC profiles (CK20+, CDX2+). Twenty-nine patients (90%) received first- and/or second-line colorectal chemotherapy regimens (response rates of 69% and 54%, respectively). Median, 2- and 4-year survivals for all 32 patients were 21 months, 42%, and 35%, respectively. Conclusion: The majority of CUP patients with colorectal molecular profile diagnoses responded to site-specific chemotherapy;median survival was similar to patients with known advanced colorectal carcinoma and superior to expected survival of CUP patients receiving empiric chemotherapy. Molecular profile assays can identify CUP patients with colorectal carcinoma;colorectal chemotherapy appears to improve outcomes. 展开更多

Primary dormancy of seeds of Korean pine(Pinus koraiensis Sieb.et Zucc.)after dispersal in the autumn and the induction of secondary dormancy the fi rst summer following seed dispersal limit the regeneration of mixed broadleaved Korean pine forests in Northeast China.This study was to determine how changes in the levels of abscisic acid(ABA)and gibberellic acid(GA)maintain primary and secondary dormancy of Korean pine seeds under germination conditions.We transferred seeds with one of fi ve primary dormancy states or three secondary dormancy states to germination conditions and measured changes in the levels of ABA,GA 1+3(GA 1 and GA 3)and GA 4+7(GA 4 and GA 7)in the seed coat,megagametophyte and embryo during incubation.Seed coat ABA levels in primary dormant seeds(PDS)and ABA levels in various parts of secondary dormant seeds(SDS)gradually declined during incubation but were still higher than in seeds for which dormancy was progressively released.GA 4+7 and GA 1+3 levels in embryos greatly decreased 35%and 24%,respectively,during incubation of SDS,and thus,the ratio of ABA to GA 4+7 in embryos and megagametophytes signifi cantly increased.The ratio of ABA to GA 1+3 in various parts of SDS increased slightly during incubation.In contrast,in seeds for which secondary dormancy was already released,GA 4+7 and GA 1+3 levels in the embryo,GA 4+7/ABA ratio in the embryo and seed coat,and the GA 1+3/ABA in the embryo and megagametophyte signifi cantly increased during incubation.There was no trend in the changes in the levels of ABA,GA 4+7 or GA 1+3 in embryos and megagametophytes of PDS or the levels of GA 4+7 or GA 1+3 in megagametophytes of SDS during incubation.The results suggest that high ABA levels in the seed coat maintain primary dormancy of Korean pine seeds.Maintenance of secondary dormancy involves a reduction of GA 4+7,GA 1+3,GA 4+7/ABA,and GA 1+3/ABA and the retention of high ABA levels. 展开更多

Introduction: Provoked vestibulodynia affects 12% of the general female population and more specifically, 21% of women aged less than 30 years. Primary and secondary vestibulodynia are hypothesized to represent the endpoints of different etiologic pathways, although there is still little research addressing potential distinctions between these two groups, particularly with regard to sexuality. Aims: To compare sexual activity and behavior of women with provoked primary vestibulodynia (PVD1) and secondary vestibulodynia (PVD2) against age-matched controls. Methods: Fifty-seven participants (N = 57), mean age 25.72 (18-41) recruited from a gynecology clinic underwent a gynaecological examination and completed a self-report questionnaire: 20 (N = 20) were diagnosed with primary provoked vestibulodynia (PVD1), 19 (N = 19) with secondary provoked vestibulodynia (PVD2), and 18 (N = 18) were medically confirmed as no-pain controls. Main outcome: To verify any differences in the sexual behavior between primary, secondary vestibulodynias and controls. Results: Mean pain duration differed significantly in participants with PVD1 at 73.8 months against those with PVD2 at 37.4 months (p = 0.003). Frequency of sexual activity also differed significantly between the three groups (p = 0.012): the controls were at 27.8% against 0% in primary and secondary vestibulodynias for once or more a day. No significant difference was observed for the sexual arousal time and masturbation frequency. Vaginal penetration was overrepresented in controls (p 0.001) contrary to fellatio frequency (p = 0.016). Pain digital test was significantly different between the three groups in one finger (3.85 vs 0.08), two fingers (4.39 vs 0.06) or three fingers (5.39 vs 0.56) (PVD1 against controls), lubricated inserted fingers for pain verification (p 0.001). Conclusions: Provoked vestibulodynia generates problems in the sexual response and coital activity, this syndrome reflecting absence of pre-existing sexual problems, notably in the masturbatory activity and oral receptive female sex. 展开更多

These plants can be used in various fields and preservation of these plants in their environment. The present study aimed to screen medicinal plants used in traditional medicine in Medina valleys for the presence of metabolites, and to answer the following question: is the ethnomedicinal importance of medicinal plants used in Medina valleys conform to their primary and secondary metabolite content. Eight plants (Pulicaria incise, Heliotropium arbainense, Commicarpus grandiflorus, Rumex vesicarius, Senna alexandrina, Rhazya stricta, Withania somnifera and Asphodelus fistulosus) were collected from the Medina valleys and were biochemically analyzed to determine the different compounds after leaves extraction analyzed statistically to clarify the content of primary compounds. The chemical compounds in the most active fraction were determined using quantitative phytochemical and gas chromatography-mass spectrometry (GC/MS) analytical methods, comparing the mass spectra of the GC/MS identified compounds with those of the Center of Excellence in Environmental Studies (CEES) database library. The result showed 16 aroma compounds representing the GC/MS analysis revealed the presence of various compounds like 4,4-Dimethyl octane, 5H-1-Pyrindine and 1,3- Cyclopentadiene, 1,2,5,5-tetramethyl- in the ethanolic extract of Pulicaria incisa. The most prevalent plants were Pulicaria incisa, Senna alexandrina and Heliotropium arbainense the study plants have high content of protein. There is a need to focus phytochemical screening on ethnobotanical studies to complete research into traditional medicine which leads to the discovery of new drugs. 展开更多
