ABSTRACT
Objective:To analyze the epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) in Qiqihar City, and to understand the epidemic and development rules of HFRS, and to provide scientific basis for formulating targeted prevention and control measures.Methods:The data of HFRS cases in Qiqihar City from 2016 to 2020 were collected from the China Disease Control and Prevention Information System by retrospective analysis, and the three distributions (time, region and population distribution) of HFRS were analyzed by descriptive epidemiology. At the same time, the monitoring data of rats in Nehe City from 2016 to 2020 were collected from the Nehe Municipal Center for Disease Control and Prevention for descriptive analysis.Results:From 2016 to 2020, 868 HFRS cases were reported in Qiqihar City, with 10 deaths. The average annual incidence rate was 3.26/100 000, the average annual mortality rate was 0.04/100 000, and the case fatality rate was 1.15%. From 2016 to2020, the incidence rates were 3.23/100 000, 3.31/100 000, 3.22/100 000, 4.10/100 000 and 2.43/100 000, respectively. Incidence occurred in all months of the year, with the peak period from October to December (490 cases in total). The top five counties(cities) with the incidence of HFRS were Nehe City (7.46/100 000), Keshan County (5.03/100 000), Gannan County (3.84/100 000), Fuyu County (3.82/100 000) and Tailai County (3.63/100 000). Among the patients, 76.04% (660/868) were male and 23.96% (208/868) were female; the age of onset was mainly 30-69 years old, accounting for 81.57% (708/868) of the total cases; the occupation distribution was mainly farmers, accounting for 75.46% (655/868) of the total cases. The results of rat monitoring in Nehe City from 2016 to 2020 showed that Rattus norvegicus was the dominant species in the field and village, accounting for 65.13% (581/892) and 80.21% (466/581), respectively. In spring, the rat density in the field and village was 3.37% (397/11 771) and 6.64% (275/4 141), respectively; in autumn, the rat density in the field and village was 8.47% (495/5 843) and 9.40% (306/3 254), respectively. The virus carrying rate of Rattus norvegicus was high, 13.14% (131/997); the infection rate of Rattus norvegicus was also high, 15.15% (151/997); the virus carrying rate and infection rate in the village were higher than those in the field (χ 2 = 6.87, P = 0.009; χ 2 = 13.05, P < 0.001). Conclusions:The incidence of HFRS in Qiqihar City is relatively stable from 2016 to 2018, rising in 2019 and falling back in 2020; the onset time is mainly in autumn and winter, mainly male and farmers. From 2016 to 2020, among all counties (cities, districts) in Qiqihar City, the incidence of HFRS in Nehe City is high, and the density of rats in autumn is higher than that in spring. Rattus norvegicus is the main species of rats, with high virus carrying rate and infection rate.
ABSTRACT
Objective@#Resting state functional magnetic resonance imaging (rsfMRI) provides a lot of evidence for local abnormal brain activity in schizophrenia, but the results are not consistent. Our aim is to find out the consistent abnormal brain regions of the patients with schizophrenia by using regional homogeneity (ReHo), and indirectly understand the degree of brain damage of the patients with drug-naive first episode schizophrenia (Dn-FES) and chronic schizophrenia. @*Methods@#We performed the experiment by activation likelihood estimation (ALE) software to analysis the differences between people with schizophrenia group (all schizophrenia group and chronic schizophrenia group) and healthy controls. @*Results@#Thirteen functional imaging studies were included in quantitative meta-analysis. All schizophrenia group showed decreased ReHo in bilateral precentral gyrus (PreCG) and left middle occipital gyrus (MOG), and increased ReHo in bilateral superior frontal gyrus (SFG) and right insula. Chronic schizophrenia group showed decreased ReHo in bilateral MOG, right fusiform gyrus, left PreCG, left cerebellum, right precuneus, left medial frontal gyrus and left anterior cingulate cortex (ACC). No significant increased brain areas were found in patients with chronic schizophrenia. @*Conclusion@#Our findings suggest that patients with chronic schizophrenia have more extensive brain damage than FES, which may contribute to our understanding of the progressive pathophysiology of schizophrenia.
ABSTRACT
The individualization of cancer treatment has brought about revolution in clinical practice. In recent years, EGFR-TKI has shown good anti-tumor activity in non-small cell lung cancer with EGFR positive mutation. Compared with the first-generation EGFR-TKI, the third-generation EGFR-TKI significantly increased the effective rate, progression-free survival and overall survival of advanced non-small cell lung cancer with EGFR mutation, especially the brain metastases. And the third-generation EGFR-TKI also showed the benefits of disease-free survival as the post-operative adjuvant therapy for operable EGFR-mutated non-small cell lung cancer. Moreover, the third-generation EGFR-TKI in combination with radiotherapy showed obvious advantages in the treatment of locally advanced and advanced oligometastatic EGFR-mutated non-small cell lung cancer.

ABSTRACT
The pathogenesis of vascular cognitive impairment (VCI) remains unclear. There is a lack of specific treatment methods, and there is no unified evaluation standard for its clinical efficacy. In recent years, in addition to traditional drug therapy, the role of non-drug therapy in VCI therapy has gradually attracted attention. This article reviews the drug therapy, non-drug therapy and preventive interventions to improve the cognitive symptoms of VCI.
ABSTRACT
Objective To investigate the clinical characteristics of acute pulmonary embolism in the elderly and its differences between the elderly and non-elderly patients,and explore the predictive effect of red blood cell distribution width(RDW)on chronic thromboembolic pulmonary hypertension (CTEPH)in patients with acute pulmonary embolism.Methods A total of 129 consecutive patients with acute pulmonary embolism admitted into Affiliated Hospital of Binzhou Medical College were selected from Jan.2009 to Dec.2013.Clinical data including the basic data,blood routine test,blood gas analysis,Doppler echocardiography during admission were retrospectively analyzed.All the patients were followed-up.Ancillary findings and changes of the disease were recorded in detail during the follow-up period.SPSS 19.0 was used to analyze the results.Results The incidences of CEPPH and venous thromboembolism(VTE)in APE patients were higher in the elderly than in non-elderly.The mean RDW and pulmonary arterial systolic pressure on admission in APE patients were higher in the elderly than in non-elderly [(14.22±2.11)％ vs.(13.48± 1.69)％,P=0.033,for mean RDW] and [(54.82± 21.77)mmHg vs.(42.20 ± 19.36) mmHg,P=0.010 for pulmonary arterial systolic pressure].The mean RDW was higher in CTEPH patients than in patients without CTEPH [(16.79 ± 3.08) ％ vs.(13.68± 1.68)％,P=0.016].Multivariate Logistic analyses showed that the increased RDW level was an independent risk factors for CTEPH in APE patients(OR=1.535,95％ CI:1.094-2.155,P=0.013).The area under receiver operating characteristics curve(AUC)of RDW level for predicting CTEPH in APE patients was 0.856(95％ CI:0.706-0.987,P＜0.001),the corresponding cut-off point was 14.85％,and the sensitivity and specificity were 88.9％ and 87.5％ respectively.Conclusions The increased RDW level could predict the risk of CTEPH to a certain extent in APE patients.
ABSTRACT
Objective To investigate the application of statins in secondary prevention of ischemic stroke in different risk groups,and to identify the factors influencing the comphcance of statins.Me.ods Ischemic stroke patients from December 2011 to October 2012 were collected.All clinical characterisitcs and possible factors influencing the compliance of statins was recorded in 3 months.The multivariate Logistic regression analysis was used to analyze the influencing factors of the compliance of statins.Results All 368 patients were collected,and 67.9％(250/368) patients were prescribed statins for therapy during hospitalization.The application rate of statins in accordance with guidelines in high-risk,extremely high-risk Ⅱ and extremely high-risk Ⅰ patients was 28.1％ (18/64),44.1％ (30/68) and 72.3％ (136/188),respectively.Logistic regression analysis showed that the statins application during hospitalization was associated with the presence of carotid vulnerable plaques (OR =5.308,P =0.000) and diabetes history (OR =1.789,P =0.032).Routine discharge instructions had high compliance.Conclusion The compliance of statins in secondary prevention of ischemic stroke still has a large gap between clinical practice and guidelines,and routine discharge instructions on statins application increase the compliance of statins.
