Hypercoagulable state (HCS) after kidney transplantation is one of the common and serious complications in kidney transplant recipients, which has attracted increasing attention in recent years. HCS refers to the abnormal and excessive activation of blood coagulation function, leading to the increased risk of thrombosis. After kidney transplantation, the combined effects of hemodynamic changes, surgical trauma and severe rejection increase the incidence of HCS, not only raising the risk of thrombosis but also potentially causing graft failure and affecting the postoperative survival rate of patients. This article reviews the influencing factors, clinical manifestations, diagnostic methods and preventive strategies of HCS after kidney transplantation, aiming to provide a theoretical basis for optimizing perioperative management and improving the prognosis of patients.

Objective:To investigate the efficacy and safety of intravenous thrombolysis (IVT) in patients with acute ischemic stroke (AIS) who are currently using direct oral anticoagulants (DOACs).Methods:Patients with AIS admitted to the Stroke Center of Zhengzhou People's Hospital from January 2021 to December 2024 and had taken DOACs within 48 hours prior to onset were included retrospectively. The demographic characteristics, vascular risk factors, laboratory test results, baseline National Institutes of Health Stroke Scale (NIHSS) scores, and other clinical data were collected. The main outcome measure was the functional outcome evaluated using the modified Rankin Scale at 90 days after onset, with a score of 0-2 defined as good outcome. The secondary outcome measures were symptomatic intracranial hemorrhage (sICH) and any bleeding in any location occurring within 36 hours after onset. Multivariate logistic regression analysis was used to determine the independent influencing factors of the outcome. Results:A total of 153 patients were included, with 87 males (56.9%), aged (71.261±6.983) years. Seventy-four patients (48.4%) underwent IVT, and 59 (38.6%) had poor outcome. The good outcome rate in the IVT group was significantly higher than that in the non-IVT group (71.6% vs. 51.9%; χ2=6.274, P=0.012), but there was no significant difference in the incidence of sICH and any bleeding in any location. The baseline NIHSS score of the good outcome group was significantly lower than that of the poor outcome group (8.817±3.677 vs. 11.203±5.060; t=3.361, P<0.001), and the proportion of IVT was significantly higher than that of the poor outcome group (56.4% vs. 35.6%; χ2=6.274, P=0.012). Multivariate logistic regression analysis showed that previous history of stroke or transient ischemic attack (odds ratio [ OR] 3.964, 95% confidence interval [ CI] 1.611-9.753; P=0.003) and high baseline NIHSS score ( OR 1.129, 95% CI 1.034-1.233; P=0.007) were independently associated with the poor outcome, while IVT was independently associated with the good outcome ( OR 0.166, 95% CI 0.068-0.410; P<0.001). Conclusion:For patients with AIS who had taken DOACs within 48 hours before onset, IVT can significantly improve the outcome without increasing the risk of sICH.

OBJECTIVE To establish the quality control method of Flueggea suffruticosa. METHODS The microscopical identification and thin layer chromatography （TLC） of F. suffruticosa were carried out， and the mass fractions of moisture， total ash， acid-insoluble ash and alcohol-soluble extracts in F. suffruticosa were measured based on the 2020 version of Chinese Pharmacopoeia （part Ⅳ）. The content of securinine in medicinal materials was determined by high performance liquid chromatography. RESULTS The powder of F. suffruticosa was gray-green， with obvious microscopic characteristics such as pores， pollen grains， calcium oxalate cluster crystals， ducts. The results of TLC identification showed that in the chromatograms of 16 batches of medicinal samples， the same color spots were found on the corresponding positions of the chromatograms of securinine， rutin， quercetin and F. suffruticosa control. The average mass fractions of moisture， total ash， acid-insoluble ash and alcohol- soluble extracts in 16 batches of medicinal materials were 9.26%， 6.96%， 1.17% and 28.89%， respectively. The injection volume of securinine in the range of 0.052 4-0.524 0 µg had a good linear relationship with the peak area （R2＝0.999 8）. RSDs of precision， repeatability and stability （24 h） test were all less than 3% （n＝6 or 7）. The average recovery of sample was 97.47%， RSD was 1.63% （n＝6）. The content of securinine in 16 batches of medicinal materials was 1.003-6.872 mg/g. CONCLUSIONS The quality control method of F. suffruticosa is established， and the mass fractions of moisture， total ash and acid-insoluble ash should not exceed 12.0%， 9.0% and 2.0%， respectively； the alcohol-soluble extract should not be less than 20%， and the content of securinine should not be less than 1.00 mg/g.

Objective To explore the feasibility of individual identification based on the 2D-3D face image superimposition in Han individuals.Methods The 2D video surveillance images(including front,left and right side)and high-precision 3D face models of 10 Han individuals were collected,and Autodesk 3ds Max 2018 software was used to perform perspective matching on the 3D face models,and superimposed them on the 2D images,and the mean values of the distances between corresponding 11 feature points in the 2D-3D face images were calculated.The superimposition of 2D-3D face images from the same individual was defined as the matching group,and the superimposition of 2D-3D face images from different individuals was defined as the non-matching group.Results In general,the average distance ranges of the corresponding feature points between the matching group and the non-matching group did not overlap(P<0.05).Conclusion The non-overlapping mean range preliminarily indicates that the individual identification method based on the overlay comparison of 2D-3D face images described in this paper is feasible for Han individuals.

OBJECTIV E To optimize the s alt-processing technology of Rosa laevigata ，and to study high performance liquid chromatography（HPLC）fingerprints and chromaticity values of R. laevigata before and after salt-processing. METHODS The comprehensive scoring method was adopted to optimize the salt-processing technology of R. laevigata using appearance character ， moisture and polysaccharide content as index. Fingerprints were established by HPLC method before and after salt-processing ，and chromaticity values （L*，a*，b*）of the powder before and after salt-processing were determined. The multivariate statistical analysis was carried out for raw product and salt-processing product of R. laevigata by using common peak areas and chromaticity values as index. RESULTS The optimal salt-processing technology of R. laevigata was to mix it with appropriate amount of salt water ，place them in the preheated frying wok at 140 ℃，fry them for 25 min，and rotate frying wok 20 times/min. Ten common peaks were calibrated by HPLC fingerprints before and after salt-processing ，and 3 components were identified ，such as gallic acid ，catechin and ellagic acid. The chromaticity values L*，b* and E* changed significantly after salt-processing. The multivariate statistical analysis method could distinguish raw products and salt-processing products into two categories ，in which peaks 1，5，6 and 10 and chromaticity values b* and E* were important characteristic factors. CONCLUSIONS The optimized salt-processing technology is stable and reliable ，and the established fingerprint has good repeatability and stability. Fingerprint and chromaticity values combined with multivariate statistical analysis can provide reference for the identification and quality analysis of R. laevigata before and after salt-processing.

Objective:To study the radiation dose rate and effective dose in ambient environment due to 125I seed implantation in the treatment of the patients suffering abdominal and pelvic tumors, so as to provide reference for occupational protection of different groups. Methods:Within 24 hours after operation, the radiation dose rate to 42 patients with abdominal and pelvic tumor with 125I seed implantation was monitored by using pocket dosimeter. The relationships between the total activity in the implanted particles and the measured dose rate, as well as between the implanted depth and the dose rate under the standard activity, were obtained by curve fitting. According to the formula, the relationship between the dose rate and the warning time was calculated. Results:The dose rates at 30 cm, 50 cm and 100 cm of vertical particle implantation site were (6.92±2.87), (4.10±1.62) and (1.30±0.48) μSv/h, respectively ( χ2=73.71, P<0.05). The dose rates on the left and right sides were (0.378±0.156) and (0.384±0.153) μSv/h at 30 cm, (0.170±0.089) and (0.17±0.086) μSv/h at 50 cm, (0.039 ±0.014) and (0.043±0.017) μSv/h at 100 cm, respectively ( χ2=76.19, 76.33, P<0.05). There was a linear relationship between the dose rate at the vertical particle implantation site and the total activity in the implanted particles, and between the dose rate and the implantation depth under the standard activity. The relationship between the warning time and the dose rate to adults in the same bed, co-workers, minors in the same bed and pregnant women were as follows: t ( d)=-106.616+ 83.779ln D( t), t ( d)=26.556+ 85.933ln D ( t), t( d)=3.088+ 85.017ln D( t). Conclusions:After 125I seed implantation, the radiation dose in the ambient environment is low, ensuring the radiation safety; and the measured dose rate decreases with the decrease in the total activity in the implanted particle and the increase in the implantation depth; at the same time, the warning time for different groups is calculated according to the measured dose rate or the total activity in the implanted particle and the depth of the implanted particle, so as to carry out individualized protection.
