Objective:To compare the efficacy of catheter-directed thrombolysis versus catheter-directed thrombectomy for high-risk pulmonary embolism.Methods:The clinical data of 105 patients with high-risk pulmonary embolism from April 2020 to January 2023 in Hebei China Petroleum Central Hospital were retrospectively analyzed. Among them, 52 patients were treated with catheter-directed thrombolysis (thrombolysis group), and 53 patients were treated with catheter-directed thrombectomy (thrombectomy group). The efficacy, symptom relief time, oxygen saturation recovery time, mortality rate, Qanadli embolic index, pulmonary artery pressure and complications were compared between two groups.Results:There were no statistical differences in total effective rate, symptom relief time, oxygen saturation recovery time, mortality rate and total incidence of complications between two groups ( P>0.05). Compared with before treatment, the Qanadli embolic index and pulmonary artery pressure after treatment in thrombolysis group and thrombectomy group were significantly lower, thrombolysis group: 22.08 ± 8.57 vs. 45.18 ± 13.27 and (24.18 ± 5.19) mmHg (1 mmHg = 0.133 kPa) vs. (34.15 ± 6.22) mmHg, thrombectomy group: 23.11 ± 8.62 vs. 44.82 ± 13.14 and (23.66 ± 5.02) mmHg vs. (34.89 ± 6.27) mmHg, and there were statistical differences ( P<0.01); but there was no statistical difference the Qanadli embolic index and pulmonary artery pressure before and after treatment between two groups ( P>0.05). Conclusions:In patients with high-risk pulmonary embolism, both catheter-directed thrombolysis and catheter-directed thrombectomy have good efficacy and can promote the relief of clinical symptoms and the recovery of oxygen saturation, improving the prognosis.

OBJECTIVE@#To investigate serum thyroid stimulating hormone (TSH) level and its changes with age in apparently healthy Chinese elderly population and analyze the differences between TSH levels detected using Roche and Snibe electrochemiluminescence immunoassay analyzers.@*METHODS@#General clinical data and frozen fasting serum samples were collected from 5451 apparently healthy Chinese elderly individuals (> 60 years) from 10 centers in different geographic regions in China. Thyroid function indexes including TSH level were detected using Roche and Snibe electrochemiluminescence immunoassay analyzer, and the median (2.5% and 97.5% quantiles) TSH level was calculated. The variations of TSH level among the participants with geographic regions, gender, and age (with an interval of 5 years) were analyzed to determine the influence of these factors on TSH level.@*RESULTS@#The reference ranges of serum TSH level established using Roche and Snibe electrochemiluminescence immunoassay analyzers were 0.42-9.47 mU/L and 0.36-7.98 mU/L, respectively, showing significant differences between the two methods (P < 0.001). The TSH levels measured at two centers in Western China were significantly higher than those at the other centers (P < 0.05). In elderly male population, serum TSH level tended to increase with age, which was not observed in elderly female population. At the age of 60-75 years, women generally had higher serum TSH level than men, but this difference was not observed in the population beyond 75 years.@*CONCLUSION@#In elderly population, serum TSH level can vary with geographic region, gender, and age, but there was no need for establishing specific reference ranges for these factors. The differences between different detection methods should be evaluated when interpreting the detection results of TSH level.

OBJECTIVE@#To analyze the influenza vaccination trend of hospitalized elderly people (≥ 60 years old) in Beijing from 2013 to 2019.@*METHODS@#The influenza vaccination status and hospitalization information of elderly people were extracted from the Beijing Elderly Influenza Vaccination database (2013-2019) and the Beijing Urban Employee Basic Medical Insurance database (2013-2019), se-parately. The influenza vaccine coverage rates and annual percentage change were calculated to compare the vaccination trends of elderly people hospitalized due to different diseases. The subjects in 2018-2019 influenza season were divided into different groups according to demographic status, health conditions and hospitalization outcomes to describe and compare the distribution of influenza vaccination rates.@*RESULTS@#The influenza vaccine coverage rates among the elderly people hospitalized due to cardiovascular diseases, cerebrovascular diseases, respiratory diseases or diabetes mellitus were 14.6%, 13.4%, 13.4% and 11.8%, respectively. The influenza vaccination rate among those hospitalized for cardiovascular diseases remained the highest across six influenza seasons and those hospitalized for diabetes mellitus remained the lowest. The largest annual decline of influenza vaccine coverage rate was observed among the hospitalized elderly due to diabetes mellitus (-7.85%). The distribution of vaccinated population was significantly associated with age, gender, hospitalization outcome and comorbidities among the hospitalized elderly people with specific diseases in 2018-2019. Among the elderly people hospitalized due to four different diseases, the vaccination rate of the patients aged 70-79 years was higher than that of the other age groups and that of the patients aged 60-69 years was the lowest. Among the elderly people hospitalized due to respiratory diseases, the vaccination rate of men was higher than that of women, while the situation reversed among the elderly people hospitalized due to cardiovascular diseases and diabetes mellitus. Vaccination rates decreased among the older adults with poor hospitalization outcomes. Among the elderly people hospitalized due to diabetes mellitus, those with 0 comorbidity had the lowest vaccination rate (7.9%).@*CONCLUSION@#The trend of influenza vaccine coverage rates among the elderly people in Beijing from 2013 to 2019 was downward. We should pay more attention to influenza vaccination in elderly people with diabetes mellitus and aged 60-69 years, and carry out more research on the protective effects of influenza vaccine to promote influenza vaccine coverage among people with chronic diseases.

OBJECTIVES@#To explore the optimal maintenance dose of caffeine citrate for preterm infants requiring assisted ventilation and caffeine citrate treatment.@*METHODS@#A retrospective analysis was performed on the medical data of 566 preterm infants (gestational age ≤34 weeks) who were treated and required assisted ventilation and caffeine citrate treatment in the neonatal intensive care unit of 30 tertiary hospitals in Jiangsu Province of China between January 1 and December 31, 2019. The 405 preterm infants receiving high-dose (10 mg/kg per day) caffeine citrate after a loading dose of 20 mg/kg within 24 hours after birth were enrolled as the high-dose group. The 161 preterm infants receiving low-dose (5 mg/kg per day) caffeine citrate were enrolled as the low-dose group.@*RESULTS@#Compared with the low-dose group, the high-dose group had significant reductions in the need for high-concentration oxygen during assisted ventilation (P=0.044), the duration of oxygen inhalation after weaning from noninvasive ventilation (P<0.01), total oxygen inhalation time during hospitalization (P<0.01), the proportion of preterm infants requiring noninvasive ventilation again (P<0.01), the rate of use of pulmonary surfactant and budesonide (P<0.05), and the incidence rates of apnea and bronchopulmonary dysplasia (P<0.01), but the high-dose group had a significantly increased incidence rate of feeding intolerance (P=0.032). There were no significant differences between the two groups in the body weight change, the incidence rates of retinopathy of prematurity, intraventricular hemorrhage or necrotizing enterocolitis, the mortality rate, and the duration of caffeine use (P>0.05).@*CONCLUSIONS@#This pilot multicenter study shows that the high maintenance dose (10 mg/kg per day) is generally beneficial to preterm infants in China and does not increase the incidence rate of common adverse reactions. For the risk of feeding intolerance, further research is needed to eliminate the interference of confounding factors as far as possible.

OBJECTIVES@#To evaluate the early risk factors for death in neonates with persistent pulmonary hypertension of the newborn (PPHN) treated with inhaled nitric oxide (iNO).@*METHODS@#A retrospective analysis was performed on 105 infants with PPHN (gestational age ≥34 weeks and age <7 days on admission) who received iNO treatment in the Department of Neonatology, Children's Hospital of Nanjing Medical University, from July 2017 to March 2021. Related general information and clinical data were collected. According to the clinical outcome at discharge, the infants were divided into a survival group with 79 infants and a death group with 26 infants. Univariate and multivariate Cox regression analyses were used to evaluate the risk factors for death in infants with PPHN treated with iNO. The receiver operating characteristic (ROC) curve was used to calculate the cut-off values of the factors in predicting the death risk.@*RESULTS@#A total of 105 infants with PPHN treated with iNO were included, among whom 26 died (26/105, 24.8%). The multivariate Cox regression analysis showed that no early response to iNO (HR=8.500, 95%CI: 3.024-23.887, P<0.001), 1-minute Apgar score ≤3 points (HR=10.094, 95%CI: 2.577-39.534, P=0.001), a low value of minimum PaO2/FiO2 within 12 hours after admission (HR=0.067, 95%CI: 0.009-0.481, P=0.007), and a low value of minimum pH within 12 hours after admission (HR=0.049, 95%CI: 0.004-0.545, P=0.014) were independent risk factors for death. The ROC curve analysis showed that the lowest PaO2/FiO2 value within 12 hours after admission had an area under the ROC curve of 0.783 in predicting death risk, with a sensitivity of 84.6% and a specificity of 73.4% at the cut-off value of 50, and the lowest pH value within 12 hours after admission had an area under the ROC curve of 0.746, with a sensitivity of 76.9% and a specificity of 65.8% at the cut-off value of 7.2.@*CONCLUSIONS@#Infants with PPHN requiring iNO treatment tend to have a high mortality rate. No early response to iNO, 1-minute Apgar score ≤3 points, the lowest PaO2/FiO2 value <50 within 12 hours after admission, and the lowest pH value <7.2 within 12 hours after admission are the early risk factors for death in such infants. Monitoring and evaluation of the above indicators will help to identify high-risk infants in the early stage.

There were three new blood group systems including the KANNO blood group system, the Sid blood group system and the CTL2 blood group system (provisional status), have been registered by the International Society of Blood Transfusion (ISBT) registered Science August 2019. The main reason for this update is that the significant SNPs of the KANNO blood group system (rs1800014) and the Sid blood group system (rs7224888) have been found through genome-wide association studies and whole exome sequencing. The new genetic evidences are consistent with the current immunological findings. In addition, although CTL2 antigen has been found on erythrocyte ghost (erythrocyte membrane) since 2017, CTL2 blood group system is still in provisional status due to lack of serological and genetic evidence. In this review, the experimental research advances of these three ISBT blood group systems and discuss the clinical value of the relevant researches was summarized briefly.

Based on the field investigations in 91 investigation sites (counties) in southwest China between 2001 and 2019, the present paper reported the chigger mites on A. agrarius mice in southwest China for the first time by using a series of statistical methods. From 715 striped field mice captured in 28 of 91 investigated sites, only 255 chiggers were collected, and they were identified as 14 species, 6 genera in 3 subfamilies under 2 families. Of 715 A. agrarius mice, only 24 of them were infested with chigger mites with low overall prevalence (PM=3.4%), overall mean abundance (MA=0.36 mites/host) and overall mean intensity (MI=10.63 mites/host). The species diversity and infestation of chiggers on A. agrarius were much lower than those previously reported on some other rodents in southwest China. On a certain species of rodent, A. agrarius mouse in southwest China seems to have a very low susceptibility to chigger infestations than in other geographical regions. Of 14 chigger species, there were 3 dominant species, Leptotrombidium sialkotense, L. rupestre and Schoengastiella novoconfuciana, which were of aggregated distribution among different individuals of A. agrarius hosts. L. sialkotense, one of 6 main vectors of scrub typhus in China, was the first dominant on A. agrarius. The species similarity of chigger mites on male and female hosts was low with CSS=0.25, and this reflects the sex-bias of different genders of A. agrarius mice in harboring different chigger species.

The present study was aimed to explore the correlation between θ-γ neural oscillations phase-amplitude coupling (PAC) in hippocampal CA3 area and the changes of spatial identifying and cognitive ability before and after shock avoidance training in rats. According to the results of Y-type maze shock avoidance training, the rats were divided into two groups: the fast avoidance response group and the general avoidance response group. The local field potential (LFP) of hippocampal CA3 area was recorded by wireless telemetry before and after shock avoidance training. The variation of θ oscillation (3-7 Hz) and low-γ neural oscillation (30-60 Hz) PAC in hippocampal CA3 area was analyzed by MATLAB wavelet packet extraction technique. The results showed that, compared with the general avoidance response group, the fast avoidance response group exhibited higher θ-γ neural oscillation PAC in hippocampal CA3 area before training. θ-γ oscillation PAC in hippocampal CA3 area was increased in both groups after training. It was also noticed that θ-γ neural oscillation PAC of some frequency bands in the general avoidance response group were significantly higher than those in the fast avoidance response group. The results suggest that certain intensity of training can change the spatial identifying and cognitive ability of rats, and the mechanism may involve the increase of the synchrony of θ-γ neural oscillation, i.e., the enhancement of θ-γ phase-amplitude alternating frequency coupling in hippocampal neurons.

This paper is to illustrate the infestation and related ecological characteristics of chigger mites on the Asian house rat (Rattus tanezumi). A total of 17,221 chigger mites were collected from 2,761 R. tanezumi rats, and then identified as 131 species and 19 genera in 2 families. Leptotrombidium deliense, the most powerful vector of scrub typhus in China, was the first major dominant species on R. tanezumi. All the dominant mite species were of an aggregated distribution among different individuals of R. tanezumi. The species composition and infestations of chiggers on R. tanezumi varied along different geographical regions, habitats and altitudes. The species-abundance distribution of the chigger mite community was successfully fitted and the theoretical curve equation was Ŝ (R)=37e–(0.28R)2. The total chigger species on R. tanezumi were estimated to be 199 species or 234 species, and this further suggested that R. tanezumi has a great potential to harbor abundant species of chigger mites. The results of the species-plot relationship indicated that the chigger mite community on R. tanezumi in Yunnan was an uneven community with very high heterogeneity. Wide geographical regions with large host samples are recommended in the investigations of chigger mites.

The chigger mite Leptotrombidium sialkotense is one of the 6 main vectors of scrub typhus in China. Before present study, L. sialkotense was found in some parts of Hunan province, China with a narrow geographical distribution. During field investigation 2016-2017, we found L. sialkotense in Jingha, southern Yunnan, China. Of 15 small mammal host species, L. sialkotense were collected from 6 species of the hosts. Rattus brunneusculus was a dominant host of L. sialkotense, from which 98.3% of the mites were collected. The chigger mite showed a relatively high infestation prevalence (PM=11.7%) and mean abundance (MA=0.5) in comparison with the rest 5 host species. These results reveal a certain host specificity of L. sialkotense to a rat R. brunneusculus. The mite L. sialkotense showed an aggregated distribution on the host (P<0.05). A positive correlation observed between L. sialkotense and the body length of hosts. There was a positive interspecific association between L. sialkotense and 2 other dominant vectors, L. deliense and L. scutellare.

@#【Objective】 To investigate the safety and benefit of doxorubicin loaded hydrophobic linear alkyl modified graphene oxide (DOX@GO- C18) served as vectors in transcatheter arterial chemoembolization (TACE). 【Methods】 Doxorubicin loaded hydrophobic linear alkyl modified graphene oxide was manufactured and characterized. VX2 liver carcinoma was established in rabbits and the hepatic lesions were treated with TACE using DOX@GO- C18 which was dissolved in lipiodol. Pre- and post- CT scans were performed to evaluate the treatment response. Liver function was assessed via blood samples drawn on day 0(preoperative),1,3,7,and day 14. The animals were sacrificed on day 14 and tissue samples collected to stain for pathology(hematoxylin-eosin staining),lipiodol(oil red O staining)and DOX(fluorescent).【Results】The dispersion of DOX@GO-C18 in lipiodol was highly stable. Pre-and post-CT scan revealed that the diameter of the VX2 lesions barely varied and enhancements were decreased after the treatment. Target lesions gained stable disease(SD)as the treatment response based on Response Evaluation Criteria in Solid Tumors 1.1(RECIST 1.1). Histological examination revealed that DOX@GO-C18 was located within the tumor tissue along with the lipiodol. The release of DOX may contribute to the necrosis in tumor.【Conclusions】DOX@GO-C18[CC2]may proved to be a safe and effective vectors in TACE treatment for liver carcinoma.
