Objective To study the percentage and cause of new seizure types in epilepsy patients and attempt to evaluate the value of new seizure types.Methods All 1074 eapilepsy patients were envolled in the retrospectively study.The types of seizure were diagnosed according to International League Against Epilepsy seizure classification and neuroimaging results of the patients.The Wilcoxon signed rank sum test was used to assess the difference of age at first seizure and mean duration of epilepsy patients with and without new seizure types.The chi-square test was used to compare the abnormal proportion of EEG and neuroimaging results of epilepsy patients.Results Two hundred and thirty-one(21.5%)of 1074 epilepsy patients experienced new seizure type.Five hundred and eighty-four patients had partial seizure with 132 (22.6%)experiencing new types of seizure while 490 patients had generalized seizure with 99(20.2%)experiencing new types of seizure.Five hundred and seventy-six(53.6%)had abnormal EEG and 237 (22.1%)had abnormal neuroimaging in 1074 epilepsy patients.A hundred and twenty-three(52.3%)of 231 patients with new seizure types had abnormal EEG,and 75(32.5%)of them had abnormal neuroimaging. The possible causes for the new types of seizure could be found in 41 patients.There were no significant difference in the age of the first onset between the patients with and without the new types of seizure while there was significant difference in the average course of disease between them(χ~2=18.511-23.836.P<0.05).There were significant differences in the rates of abnormal results of examination of nervous system and imaging outcomes.Conclusions There may be different causes of new seizure types.The study of new seizure types is helpful in diagnosis,treatment and prevention of epilepsy.

Objective To investigate the application of prenatal ultrasonograpy in diagnosis of fetal heart disease during the medium-term and terminal pregnancy,and to avoid misdiagnosis.Methods The prenatal ultrasonographic screening was conducted in 7020 pregnant women with medium-term and terminal pregnancy.All confirmed and suspicious cases of fetal heart disease were observed by echocardiography once 4 weeks until postnatal sixth month to 1 year while normal cases was traced at the intervals of 8 weeks.All the cases were confirmed by autopsy or surgery while part of them were confirmed by postnatal angiocardiography before surgery.The reasons of misdiagnosis were analyzed.Results In fifty-three cases of fetal cardiovascular abnormality,43 cases were found,2 cases were misdiagnosis while 8 cases were missed diagnosis.2 cases of misdiagnosis included 1 case of pulmonary valve stenosis and 1 case of tetralogy of Fallot.8 cases of miss diagnosis included 2 cases of inferior vena cava in ectopic drainage and 6 cases of ventricular septal defect (defect diameter < 5 mm).The accuracy rate of diagnosis of fetal heart disease was 81.1 % by echocardiography.Conclusions Using high frequency probe,image zoom,enhancing the detection of vein-atrium connection and the structure of right ventricular outflow with pulmonary artery are important factors to avoid missed diagnosis and incomplete diagnosis.

Abstract: Leprosy, as an important neglected tropical disease (NTDs), has a tremendous impact on the patients’body and psychology, families and society. In this paper, we reviewed the progress of epidemiology, genetic factors, immune mechanisms, diagnosis and treatment of leprosy, and introduced the changes of national prevention and control policies and the prevention and control process of Hainan Province, so as to improve the clinical understanding among healthcare professionals. According to the World Health Organization's (WHO) global annual leprosy situation report data, the number of new cases and the incidence rate of leprosy have been showing a downward trend worldwide. In China, the epidemic situation of leprosy remains in an overall low-endemic state. However, the long-standing low-endemic status of leprosy and its wide and uneven distribution pose challenges to the prevention and control of leprosy. The pathogenesis of leprosy is mainly related to skin barrier, immune deficiency, and related signaling pathways. Serological testing, cytokines, and microRNA markers can all be used to assist in the early diagnosis of leprosy, while also helping to distinguish different types of leprosy, predict leprosy reactions, evaluate efficacy, and monitor family contacts. The main treatment plan for leprosy involves combination chemotherapy with drugs recommended by the WHO, such as rifampicin, dapsone, clofazimine and other drugs. Currently, the main prevention and treatment strategies for leprosy are early detection, early diagnosis and early treatment, controlling the source of infection, protecting the healthy population, preventing the occurrence of deformity, and improving the quality of life after recovery. At present, Hainan Province as well as the whole country is in a low-epidemic state, but healthcare professionals still need to improve their awareness of prevention, reduce their incidence rate, and strive to achieve the goal of "zero leprosy" as soon as possible.

Objective To investigate the dynamic changes and its significance of inflammatory factors in cervical secretions and prior cervical tissues after cervical conical resection.Methods Women who received prior cervical conization during December 2013 and December 2015 in this hospital were selected,then the cervical tissue and secretion were collected regular interval after the conization.The expression of tumor necrosis factor-α(TNF),interleukin 6 (IL-6) and high mobility group protein 1 (HMGB1) were quantitative detected and analyzed.The expression and infiltration of inflammatory cell were detected by HE and immunohistochemical staining.Results The expression of TNF-α,IL-6 and HMGB1 in cervical tissues and secretions increased gradually after priorcervical conization,which reached the peak at 1 to 2 weeks after priorcervical conization,and then gradually decreased,the differences were statistically significant when compared with the preoperative control group (P<0.05).The inflammatory cell infiltration and the inflammatory response were most severe at 1st week after the conization.The expression of TNF-α,IL 6 and HMGB1 was at 1st week after the conization were significantly higher than that of the 4thweek group.Conclusion The cervical inflammatory were most severe after the prior cervical conization about 1-2weeks,and the hysterectomy should be avoided at this stage.

Objective:To investigate the relationship between cancer-related fatigue and cortisol in cancer patients and elucidate the underlying mechanism. Methods:A total of 80 cancer cases were divided into two groups:fatigue group (50 cases with cancer-related fatigue) and non-fatigue group (30 cases without fatigue). The scores were evaluated through the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF) and the Fatigue Symptom Inventory (FSI) report. Serum specimens were examined through electrochemiluminesence immunoassay and enzyme-linked immunosorbent assay. Serum cholesterol was examined through the CHOD-PAP method, and serum total protein and albumin were determined via the Biuret method. Agarose gel electrophoresis was conducted to determine alpha 2 globulin ratio and to calculate serum alpha 2 globulin concentration. Results: The cortisol level in the fatigue group was significantly lower than that in the non-fatigue group[(119.68±5.34) nmol/L vs. (163.45± 31.49) nmol/L, P<0.05], and the adrenocorticotropic hormone (ACTH) level in the fatigue group was significantly higher than that in the non-fatigue group [(104.50 ± 17.15) ng/L vs. (51.43±13.24) ng/L, P<0.05]. Cortisol negatively correlated with MFSI-SF (r=-0.867, P<0.001) but positively correlated with ACTH (r=0.809, P<0.001). Furthermore, cortisol negatively correlated with FSI (r=-0.747, P<0.001) but positively correlated with ACTH (r=0.70, P<0.001). The levels of serum cholesterol [(1.25±0.70) mmol/L vs. (3.28±0.73) mmol/L, P<0.05], albumin[(18.24 ± 7.03) g/L vs. (37.40 ± 8.05) g/L, P<0.05], and alpha-2 globulin [(2.25±1.07) g/L vs. (5.36±1.09) g/L, P<0.05]were significantly lower in the fatigue group than in the non-fatigue group. Conclusion:The patients with cancer-related fatigue exhibited increased MFSI-SF score, decreased serum cortisol level, and enhanced ACTH level. The low serum cortisol levels caused a disorder in the serum ACTH and cancer-related fatigue of malignant tumor patients. The mechanism underlying the reduction in serum cortisol level correlated with the insufficient amounts of serum cholesterol, the composite material of cortisols, and of serum albumin, particularly alpha-2 globulin, the carrier protein of serum cholesterol.
