Migraine is a common primary headache,which is the second leading cause of disability worldwide,espe-cially resistant and refractory migraine.Treatments for migraine are diverse.This article summarizes the progress in the prevention and treatment of resistant and refractory migraine,aiming to promote clinicians'understanding of such types of migraine.

Headache is a common disease of the nervous system,with a high risk of disability,but currently the di-agnosis rate of headache remains at a relatively low level,mainly relying on the self-treatment by patients.In recent years,as headache diseases attract more attention,headache nurses are playing an increasingly important role in the management of headache patients,and headache nursing has become an important link in improving the prognosis of patients.This ar-ticle mainly introduces the importance and necessity of headache nursing in the management of headache patients.

Objective: To calculate and compare the healthy life expectancy (HLE) of the middle-aged and elderly in China, the United States, and developing and developed countries in the European Union(EU) and analyze the impact of socioeconomic factors on HLE in different countries or regions. Methods: Four surveys from 2010 to 2019 were brought into the research. The data were collected from the China Health and Retirement Longitudinal Study, Health and Retirement Study, and the Survey of Health, Ageing and Retirement in Europe. Developed and developing countries in the EU were divided into two groups for calculation. Education level, total family wealth, and work retirement status were selected to measure socioeconomic status, and activities of daily living were used as health status indicators. We used the multi-state life cycle table method to calculate the transition probability between different health states and estimate life expectancy and HLE. Results: A total of 69 544 samples were included in the study. In terms of age, the middle-aged and elderly in the United States and developed countries of the EU have higher HLE in all age groups. In terms of gender, only Chinese women have lower HLE than men. Regarding socioeconomic factors, the middle-aged and elderly with higher education levels and total family wealth level have higher HLE. In China, working seniors have higher HLE, while for USA women and developed countries of the EU, retired or unemployed seniors have higher HLE. Conclusions: Demographic and socioeconomic factors impact HLE in different countries or regions. China should pay more attention to the health of women and the middle-aged and elderly retired with lower education and less total family wealth.

OBJECTIVE: To assess the diagnostic value of copy number variation sequencing (CNV-seq) in the genetic etiology of fetuses with nasal bone dysplasia (NBD). METHODS: A total of 217 fetuses discovered with NBD from December 2017 to December 2020 were divided into the isolated NBD group and NBD combined with other anomalies group, for which copy number variations (CNVs) were analyzed. RESULTS: A total of 40 fetal abnormalities were detected in 217 cases, with an overall abnormal rate of 18.4%. These included 31 cases with aneuploidies (14.3%, 31/217) and 9 cases with genomic CNVs (4.1%, 9/217). Five cases of trisomy 21 (3.5%, 5/144) and two CNVs cases with unknown clinical significance (1.4%, 2/144) were detected in the isolated group. As for the combined NBD group, 26 aneuploidies (35.6%, 26/73), including 19 cases with trisomy 21, 6 cases with trisomy 18, 1 case with trisomy 13, 5 cases with pathogenic CNVs (6.8%, 5/73), and 2 cases with CNVs of unknown clinical significance (2.7%, 2/73) were detected. A significant difference was detected between the two groups (P < 0.01). CONCLUSION The detection rate of CNV-seq is high for chromosomal aneuploidies and pathogenic CNVs in fetuses with NBD, particularly in those combined with other ultrasonic abnormalities.

Objective To analyze the hospitalization cost and its influencing factors of imported malaria patients in Guangxi Zhuang Autonomous Region and Yunnan Province, so as to provide insights into the evaluation of the economic burden due to imported malaria, and the guiding of malaria control and the rational allocation of medical resources. Methods The data pertaining to the hospitalization costs of imported malaria patients admitted to Shanglin County People’s Hospital in Guangxi Zhuang Autonomous Region during the period from January 1 through December 31, 2019, and Tengchong Municipal People’s Hospital in Yunnan Province from January 1, 2015 to December 31, 2019, were collected, and the epidemiological data of these imported malaria patients were extracted from the Information Management System for Parasitic Diseases Control and Prevention, China. The composition of the hospitalization expenses was analyzed using a descriptive method. In addition, the factors affecting the hospitalization expenses of imported malaria patients were identified using a univariate analysis and a recursive system model. Results A total of 206 imported malaria patients were included in this study, including 194 men (94.17%) and 12 women (5.83%). The mean length of hospital stay was 5.00 days per patient and the median hospitalization expenses were 2 813.07 Yuan per time, in which the expenses for laboratory examinations were the highest (45.31%, 1 274.62/2 813.07). Univariate analysis showed that hospital (z = 5.43, P < 0.01), type of malaria (χ² = 34.86, P < 0.01) and type of payment (χ² = 7.72, P < 0.05) were factors affecting the hospitalization expenses of imported malaria patients. Recursion system modeling revealed that the total effects on hospitalization expenses of imported malaria patients included length of hospital stay (0.78), selection of hospital (0.34), basic medical insurance for urban and rural residents (0.19), new rural cooperative medical care (0.17), Plasmodium falciparum malaria (0.15), gender (0.11) and P. vivax malaria (0.09). Conclusions The hospitalization expenses of imported malaria patients are affected by multiple factors in Guangxi Zhuang Autonomous Region and Yunnan Province, in which the length of hospital stay is the most predominant influencing factor. A reduction in the length of hospital stay is effective to decrease the hospitalization expenses of imported malaria patients.

The United Nations Sustainable Development Goal proposes to achieve universal health coverage by 2030， and the key element is that everyone can enjoy high-quality healthcare services. Cardiovascular diseases， predominantly acute coronary syndromes， have become the largest disease burden on global health. However， the quality of healthcare services for acute coronary syndromes varies significantly across the populations and regions. This study aimed to investigate the difference in the quality of acute coronary syndrome services in multiple countries， regions， hospitals， and patient populations， and then determine the impact of quality improvement initiatives on quality disparity， which may facilitate further improving the equity of clinical service quality for acute coronary syndromes and promoting health equity and universal health coverage.

ResultsA total of 4 randomized controlled studies involving 3 827 patients， including 1 840 patients in the experimental group and 1 987 patients in the control group. Meta-analysis results showed that， in terms of effectiveness， compared with the control group， the proportion of patients in the Rimegepant group who were painless 2 hours after medication （RR=1.67， 95 % CI： 1.44~1.94， P<0.01）， MBS free 2 hours after medication （RR=1.37， 95% CI： 1.24~1.51， P<0.01） and pain relief （RR=1.33， 95% CI： 1.25~1.41， P<0.01）， pain relief lasting 2~24 hours after medication （RR=1.59， 95% CI： 1.46~1.74， P<0.01）， pain relief lasting 2~48 hours after medication （RR=1.57， 95% CI： 1.42~1.74， P<0.01）， painless 2~24 hours after medication （RR=2.27， 95% CI： 1.62~3.20， P<0.01）， painless 2~48 hours after medication （RR=2.14， 95% CI： 1.52~3.02， P<0.01）， and no fear of light （RR=1.47， 95% CI： 1.32~1.64， P<0.01） and no fear of sound 2 hours after medication （RR=1.40， 95% CI： 1.19~1.64， P<0.01） was higher， the differences were statistically significant. In terms of safety， the proportion of patients with nausea （RR=1.70， 95% CI： 0.95~3.02， P=0.07）， urinary tract infection （RR=1.81， 95% CI： 0.84~3.91， P=0.13）， dizziness （RR=1.14， 95% CI： 0.49~2.63， P=0.77） or elevated transaminase （RR=0.76， 95% CI： 0.45~1.27， P=0.29） showed no statistically significant differences between the Rimegepant group and the control group. Based on GRADE criteria， evidence for Rimegepant in the treatment of acute migraine was of high or moderate quality. ConclusionRimegepant is effective for acute migraine， and the toxic effects are tolerable.

BACKGROUND: Previous Caucasian studies have described venous thromboembolism in pregnancy; however, little is known about its incidence during pregnancy and early postpartum period in the Chinese population. We investigated the risk of venous thromboembolism in a “real-world” cohort of pregnant Chinese women with no prior history of venous thromboembolism. METHODS: In this observational study, 15,325 pregnancies were identified in 14,162 Chinese women at Queen Mary Hospital, Hong Kong between January 2004 and September 2016. Demographic data, obstetric information, and laboratory and imaging data were retrieved and reviewed. RESULTS: The mean age at pregnancy was 32.4±5.3 years, and the median age was 33 years (interquartile range, 29–36 yr). Pre-existing or newly diagnosed diabetes mellitus was present in 627 women (4.1%); 359 (0.7%) women had pre-existing or newly detected hypertension. There was a small number of women with pre-existing heart disease and/or rheumatic conditions. Most deliveries (86.0%) were normal vaginal; the remaining were Cesarean section 2,146 (14.0%). The incidence of venous thromboembolism was 0.4 per 1,000 pregnancies, of which 83.3% were deep vein thrombosis and 16.7% were pulmonary embolism. In contrast to previous studies, 66.7% of venous thrombosis occurred in the first trimester. CONCLUSION: Chinese women had a substantially lower risk of venous thromboembolism during pregnancy and the postpartum period compared to that of Caucasians. The occurrence of pregnancy-related venous thromboembolism was largely confined to the early pregnancy period, probably related to the adoption of thromboprophylaxis, a lower rate of Cesarean section, and early mobilization.

Vimentin, a kind of type Ⅲ intermediate filament protein, is the major component of cytoskeleton of stromal cells. Increasing researches have demonstrated that vimentin is over-expressed in muiltple tumor tissues, and is closely related with the occurrence, development, invasion and metastasis of tumors. However, correlated studies including cervical neoplasm, endometrial neoplasm and ovarian neoplasm start comparatively late with inconsistent conclusions, thus, a lot of mechanisms need to be further investigated. This paper reviews the expressions and the clinical significances of vimentin in 3 kinds of gynecological malignant tumors.

Statins are a kind of hydroxymethylglutaryl-CoA (HMG-CoA) reductase inhibitors, which are commonly used to reduce cholesterol level, and prevent cardiovascular and cerebrovascular diseases. In recent years, more and more researches have showed that statins could inhibit angiogenesis through inhibiting the proliferation, invasion and metastasis of cancer cells, and could promote cancer cells apoptosis and synergetically enhance the effect of radiotherapy and chemotherapy to play a potential anti-tumor role. This paper reviews the domestic and foreign research progresses of the anti-tumor mechanisms of statins.
