Objective Exploring the use of thromboelastography（TEG) to assess the risk of bleeding in patients with acute leukemia（AL）undergoing platelet transfusion refractoriness（PTR）. Methods To investigate the differences in TEG parameters between the PTR group and the non⁃PTR group in adult AL patients, and compare the differences in PLT and TEG parameters between the bleeding group and the non⁃bleeding group in the PTR group. Results A total of 58 AL patients were positive for platelet ⁃ related antibodies, and the proportion of PTR was 48.28%. A total of 20 patients with PTR were transfused with large ⁃ dose immunoglobulin, the effective rate was 40%, and 26 patients with PTR were transfused with matching platelets, the effective rate was 42.62%。 This study observed the difference of TEG parameters between the PTR group and the non⁃PTR group, and the results showed that there were no significant differences in PLT, R value, K value, α Angle and MA value before and after platelet transfusion in the PTR group. The PLT and MA values of the non⁃PTR group were significantly different before and after transfusion（P < 0.05), while the R value, K value and α Angle were not significantly different. The PLT and MA values of the non ⁃ PTR group were significantly higher than those in PTR group after transfusion（P < 0.05）. Analysis and comparison of PLT and TEG parameters between the bleeding group and the non⁃bleeding group in patients with PTR showed that there was no significant difference in PLT value, R value, K value and α Angle of TEG, while MA value in the non⁃bleeding group was higher than that in the bleeding group, with significant difference（P < 0.05）. Conclusions Platelet count alone cannot accurately reflect the risk of bleeding in AL patients with PTR. TEG can effectively predict and evaluate the bleeding risk in AL patients, among which the maximum amplitude index has the most significant clinical significance， which is of great significance for disease evaluation and treatment guidance.

Objective: To investigate the value of uterine artery blood flow parameters [pulsation index (PI), resistance index (RI), systolic/diastolic blood flow velocity (S/D)] combine with serum β-human chorionic gonadotropin (β-HCG), progesterone (P) and estradiol (E2) in predicting abortion in pregnant women with recurrent spontaneous abortion (RSA) re-pregnancy. Methods: 145 pregnant women with RSA re-pregnancy (RSA group) who were admitted to Anhui Maternal and Child Health Hospital from January 2021 to October 2022 were selected, and 145 healthy pregnant women (control group) in our hospital during the same period were selected, pregnant women with RSA re-pregnancy were divided into abortion group (65 cases) and live birth group (80 cases) according to the pregnancy outcome. The levels of serum β-HCG, P and E2 were detected, and the uterine artery blood flow parameters were detected by transvaginal ultrasound. The factors affecting of abortion in pregnant women with RSA re-pregnancy were analyzed by multivariate Logistic regression analysis, the value of uterine artery blood flow parameters combined with serum β-HCG, P and E2 in predicting abortion in pregnant women with RSA re-pregnancy were analyzed by receiver operating characteristic (ROC) curve. Results: The levels of PI, RI and S/D in RSA group were higher than those in control group, and the levels of serum β-HCG, P and E2 were lower than those in control group (P<0.05). PI, RI and S/D in abortion group were higher than those in live birth group, and serum β-HCG, P and E2 levels were lower than those in live birth group (P<0.05). Multivariate logistic regression analysis showed that increased age, PI, RI, and S/D were independent risk factors for abortion in pregnant women with RSA re-pregnancy, and increased β-HCG, P, and E2 were independent protective factors (P<0.05). The area under the curve of uterine artery blood flow parameters combined with serum β-HCG, P and E2 to predict abortion in pregnant women with RSA re-pregnancy was 0.941, which was higher than that predicted by single index (P<0.05). Conclusion: The increase of PI, RI and S/D and the decrease of serum β-HCG, P and E2 in pregnant women with RSA re-pregnancy are closely relate to the occurrence of abortion. Uterine artery blood flow parameters combine with serum β-HCG, P and E2 have a higher predictive value for abortion in pregnant women with RSA. [ABSTRACT FROM AUTHOR]

To address the issue of crack propagation problem caused by vehicle loading, temperature loading, etc. of asphalt pavement, the electrically conductive asphalt mixtures was prepared with carbon nanotubes-carbon fibers. The resistivity values, fracture energy, ultimate load bearing capacity and microstructure of asphalt mixtures before and after the healing of cracks were analyzed, and the self-healing level of the carbon nanotubes-carbon fiber asphalt mixtures under conductive action was studied. The results show that carbon nanotubes can significantly improve the self-healing ability of asphalt mixtures at ().5% and 1.()% of carbon nanotube content. The self-healing level of conductive asphalt mixtures has a Sine function relationship with the resistivity ratio before and after the healing process. The ultimate load carrying capacity and fracture strain of the trabecular specimens can be maximally recovered at 5() °C for 20 min. [ABSTRACT FROM AUTHOR]

In the field mechanical setting procedure, the selection of the wellhead slack-off weight is now primarily based on experience. For deep horizontal wells, conservative empirical parameters can damage the packer, which has a significant impact on the setting effect and well test safety. Therefore, a string loading model of a deep horizontal well under mechanical setting was established, based on the principle of mechanical setting and fully considering the influence of wellbore trajectory, buckling friction of string, and variable cross-section of string, combined with the three-dimensional soft rod model. In the field, the model was used to construct the wellhead hanging weight release value of a deep horizontal well. The difference between the computation findings and the field measurement is 7%, indicating that the model is reliable. The parameter sensitivity analysis reveals that the main reasons affecting the axial load of the test string are the wellbore trajectory friction and buckling friction. The increase in the tubing-to-casing radial clearance and the effective axial compression load will aggravate the buckling. Severe buckling will lock the test string, so that the released wellhead hanging weight cannot be effectively transmitted. The position of the packer determines the friction caused by the wellbore trajectory in the setting stage. The closer the position is to the bottom of the well, the more the string friction and buckling friction will increase, ultimately reducing the setting efficiency. [ABSTRACT FROM AUTHOR]

A self-designed questionnaire was used anonymously to investigate the knowledge and awareness level of human papilloma viruses（HPV）and vaccination behavior among interns from four hospitals in Jiangsu Province. This study aims to explore the influencing factors of vaccination behavior. A total of 1 250 questionnaires were distributed，and 1 230 valid copies were recalled. The results showed that the awareness rate of cervical cancer was 53.6%，while that of HPV was 33.3% and 54.7% of the students were aware of HPV vaccination. The knowledge of vaccine was obtained through school education（42.0%），official propaganda （36.1%），media communication（35.2%），and interpersonal communication（30.2%）. More than 60% of the respondents believed vaccine’s safety，efficacy，and immunity duration would affect its promotion，and 54.3% of them could accept vaccines at a cost less than 500 yuan. The vaccination rate of sampled female students was 15.7%. Multi -factor logistic regression analysis showed that the higher acceptable cost of the vaccine，getting the knowledge of the vaccine through interpersonal communication，the belief that HPV can be reinfected after recovery，and education level were important factors in promoting the vaccination behavior. Learning about the vaccine through media，such as television networks，negatively impacts vaccination behavior. Therefore，it is necessary to adopt comprehensive measures to improve the vaccination rate and emphasize interpersonal communication as a means of information dissemination. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To probe into the characteristics and regularity of adverse drug reactions (ADR) induced by tigecycline, so as to provide reference for clinical rational medication. METHODS: Case reports of ADR induced by tigecycline published from Jan. 2005 to Aug. 2022 were retrieved from CNKI, VIP, Wanfang Data, PubMed, Web of Sciene and Embase. RESULTS: Totally 91 studies related to ADR induced by tigecycline were enrolled, including 108 patients, including 68 males, 37 females and 3 unknown gender; patients were mainly aged ≥60 years (61 cases, 56. 48%); patients’ primary diseases were mainly pulmonary infection and abdominal infection. The onset time of ADR induced by tigecycline ranged from 10 min after administration to 2. 5 months after administration, with most ADR occurred within 7 d after administration (72 cases, 66. 67%). ADR induced by tigecycline had involved multiple organs and (or) systems, totally 219 case-times, with digestive system damage (105 case-times, 47. 95%) being the most common, followed by hematologic system damage (77 case-times, 35. 16%). Most patients who developed ADR were improved in symptoms within 1 week after drug withdrawal or receiving symptomatic treatment (68 cases, 62. 96%). CONCLUSIONS: ADR induced by tigecycline can involve multiple organs and/ or systems, with diverse clinical manifestations, the awareness and monitoring of ADR induced by tigecycline should be strengthened during medication to reduce or avoid the occurrence of ADR, and to ensure safe medication for patients.
