This article reports a case of acute myelomonocytic leukemia (AML-M4, CBFB gene positive) with lower limb microthrombus formation after haploidentical hematopoietic stem cell transplantation, and summarizes the experience of diagnosis and treatment. The patient received achieved complete remission (CR) after routine chemotherapy, but relapsed 2 years later and underwent a haploidentical hematopoietic stem cell transplantation. During routine treatment after transplantation, the patient’s coagulation related indicators, including D-dimer (D-D), antithrombin Ⅲ (AT-Ⅲ), von Willebrand factor (vWF), fibrinogen degradation products (FDP) and fibrin monomer (FM), were dynamically observed. The patient experienced jaundice and elevated transaminases around 100 days after transplantation, and underwent plasma exchange treatment three times through the right lower limb femoral vein catheterization. After removing the venous catheter for one week, there was left ankle concavea pitting edema of the left ankle. Vascular ultrasound examination indicated the formation of microthrombus in the superficial venous plexus of the gastrocnemius muscle in the left lower limb. D-D, vWF, FDP, FM and other indicators were increased, while AT-Ⅲ levels was decreased. After 2 weeks of oral administration of 5 mg/d berritol for antithrombotic treatment, the above coagulation indicators gradually returned to normal, and the left lower limb intermuscular venous plexus thrombosis and limb swelling disappeared. Therefore, dynamic monitoring of coagulation indicators, such as D-D, AT-Ⅲ, vWF, FDP, and FM may serve as diagnostic indicators for predict transplant related microthrombus and hypercoagulable status, providing an experimental basis for effective anticoagulant treatment in clinical practice.

BackgroundAlthough many young Chinese women migrate to urban regions for better opportunities, little is known about the prevalence and awareness of having high blood pressure (HBP) in this population. This study investigated the prevalence, awareness, and factors associated with HBP among young female migrant workers in Central South China.MethodsWe conducted a cross-sectional study to identify HBP (2017 ACC/AHA guidelines) among female migrant workers aged 18-45 years in Central South China. Demographics, anthropometric measurements, hypertension-related lifestyle, awareness of HBP, and blood pressure were recorded. Logistic regression analysis was used to identify the factors associated with HBP (blood pressure ≥ 130/80 mmHg).ResultsOverall, 232 female migrants participated in the study (mean age 34.4; standard deviation: 6.4 years). The prevalence of HBP was 27.2% (95% CI [21.6-33.2]), and 88.9% of the participants were unaware of their HBP status. Having rural medical insurance (odds ratio [OR] = 20.7; 95% confidence interval 95% CI [2.1-204.8]), awareness of having HBP (OR = 5.1; 95% CI [1.4-18.5]), physical inactivity (OR = 2.9; 95% CI [1.1-7.9]), and being overweight/obese (OR = 2.7; 95% CI [1.3-6.1]) were independently associated with HBP.ConclusionsThis study revealed a high prevalence of HBP among young Chinese female migrant workers, as well as a high frequency of being unaware of their condition and some associated factors (rural medical insurance, awareness of having HBP, physical inactivity, and overweight/obesity). The uncontrolled HBP among young Chinese female migrant workers suggested that health education needs further promotion in such a population.

BackgroundUtilization of basic public health services (BPHS) allows for disease prevention and management and is an essential component for protecting health. Disparities in utilization exist between rural-to-urban migrants and their local counterparts in China. This study sought to determine the frequency of BPHS utilization and whether social support, discrimination, and sociodemographic features were risk factors for low BPHS utilization by Chinese female migrants.MethodsData were derived from a survey of female rural-to-urban migrants at nine work sites in Changsha, China. The association between social support, discrimination, sociodemographic factors and BPHS utilization was obtained using Chi-square and logistic regression analysis.ResultsBetween December 2017 and April 2018, 307 female participants completed the survey. A total of 24.7% reported having had health education, 26.1% had breast and cervical cancer screening, 27.2% had established a health care record, and 40.9% had received basic contraceptive services. Two factors were associated with the reduced likelihood of BPHS utilization: Length of migration and health record establishment (OR = 0.53; 95% CI = 0.31, 0.92) and years of education and basic contraceptive service use (OR = 0.36; 95% CI = 0.20, 0.67). The remaining six factors were associated with an increased likelihood of BPHS utilization: Living circumstances and health record establishment (OR = 2.11; 95% CI = 1.17, 3.80), health education (OR = 2.71; 95% CI = 1.51, 4.87) and cancer screening (OR = 2.38; 95% CI = 1.30, 4.36). Utilization of social support was associated with health record establishment (OR = 1.24; 95% CI = 1.06, 1.44), basic contraceptive service use (OR = 1.21; 95% CI = 1.04, 1.42) and cancer screening (OR = 1.29; 95% CI = 1.10, 1.51). Objective social support was associated with health education utilization (OR = 1.15; 95% CI = 1.04, 1.26), while subjective social support was associated with basic contraceptive service use (OR = 1.11; 95% CI = 1.05, 1.18) and cancer screening (OR = 1.10; 95% CI = 1.02, 1.17). Family location was associated with basic contraceptive service use (OR = 1.96; 95% CI = 1.12, 3.44) and migration time in Changsha was associated with basic contraceptive service use (OR = 2.24; 95% CI = 1.18, 4.27).ConclusionsOverall, there was low utilization rate for four BPHS by Chinese female migrants, and social support appears to be an important factor in this setting. Government, community, and workplace education efforts for enhancing BPHS utilization among female rural-to-urban migrants are recommended.

ObjectiveCOVID-19 vaccination is critical for pandemic control， especially in the elderly. Compared with developed countries， the rate of full vaccination and booster vaccination for the elderly in China is low， making it urgent to accelerate the process of vaccination for the elderly in China.MethodsThis study summarizes the policy experiences of the United Kingdom， the United States， Singapore， and South Korea by sorting relevant literature and government websites， analyzes the current performance and reasons for COVID-19 vaccination among the elderly in China， and explores strategic suggestions for improving COVID-19 vaccination in the elderly in terms of vaccination priority groups， service provision， and vaccination intention.ResultsIt is important to vaccination rate for the elderly in China by focusing on the priority vaccination population， establishing a permanent mechanism based on the family doctor system， and increasing the willingness to vaccinate.ConclusionContinued reinforcement of COVID-19 vaccination for the elderly is needed， and the existing vaccination model is overwhelming. We should establish a permanent mechanism based on the family doctor system to transfer from a mobilization model to a regular vaccination model.
