【Objective】 To investigate the frequency of platelet antibodies in voluntary blood donors and patients in Zhongshan, Guangdong Province, and to study the specificity and cross-matching of platelet antibodies. 【Methods】 Platelet antibodies of blood donors and patients were screened by solid-phase immunoadsorption (SPIA), rechecked by flow cytometry (FCM), and antibody specificity was identified by PakPlus enzyme immunoassay, and platelet cross-matching was simulated by SPIA. 【Results】 A total of 1 049 blood donor samples and 598 patient samples were tested, with 6 (0.57%) and 49 (8.19%) samples positive for SPIA,respectively(P<0.05); In SPIA positive samples, the positive concordance rate of FCM in blood donors and patients was 100% vs 95%, and that of enzyme immunoassay was 100% vs 88%. Among the initial screening positive samples of blood donors, 5 were anti-HLA Ⅰ antibodies, accounting for 83%, and 1 was anti CD36 antibody, accounting for 17%, with an incidence rate of 0.10%. Among the 14 samples of enzyme immunoassay positive patients, 2 were anti-GP Ⅱb/Ⅲa, 1 was anti-GP Ⅱa/Ⅱa, 8 were anti HLA Ⅰ, and 3 were mixed antibodies (HLA Ⅰ, GP Ⅱb/Ⅲa, GP Ⅰa/Ⅱa). According to the types of antibodies, HLA Ⅰ antibodies were the most common, accounting for 65% (11/17), followed by HPA related anti GP, accounting for 35% (6/17). The majority of patients had a platelet antibody positive typing rate below 30%, accounting for 71.4% (10/14). 【Conclusions】 The positive rate of platelet antibody of patients in Zhongshan area is significantly higher than that of voluntary blood donors, and most of them are anti-HLA Ⅰ and anti-GP, and the incidence of anti-CD36 is extremely low. Therefore, it is necessary to establish a known platelet antigen donor bank, and at the same time, carry out platelet antibody testing and matching of patients, which is helpful to solve the issue of platelet transfusion refractoriness.

Objective:To investigate the efficacy of thoracoscopic segmentectomy of the dominant lung segment versus thoracoscopic segmentectomy of the complex lung segment for the treatment of stage I non-small cell lung cancer (NSCLC). Methods:This is a case-control study. The clinical data of 110 patients with stage I NSCLC who received treatment in Jinhua Municipal Central Hospital from August 2019 to August 2021 were retrospectively analyzed. These patients were assigned to a control group (thoracoscopic segmentectomy of dominant lung segment, n = 58) and an observation group (thoracoscopic segmentectomy of complex lung segment n = 52) according to the surgical method. Tumor location and resection scope in each group were recorded. Perioperative indexes, lung function indexes, complications, and short-term recurrence rates were compared between the two groups. Results:The operative time in the observation group was (175.45 ± 30.72) minutes, which was significantly longer than (152.41 ± 29.83) minutes in the control group ( t = 3.99, P < 0.05). The number of nail bins in the observation group was (4.55 ± 1.23), which was significantly greater than (3.77 ± 1.16) in the control group ( t = 3.42, P < 0.05). There were no significant differences in intraoperative bleeding volume, the number of dissected lymph nodes, postoperative drainage volume, postoperative extubation time, and postoperative hospital stay between the two groups (all P > 0.05). Forced vital capacity, forced expiratory volume in the first second (FEV 1), and FEV l/FVC ratio in the observation group were (3.89 ± 0.47) L, (2.92 ± 0.36) L, and (75.06 ± 2.47)%, which were significantly higher than (3.64 ± 0.49) L, (2.68 ± 0.35) L, and (73.63 ± 2.38)% in the control group (all P < 0.05). There was a significant difference in the incidence of complications between the observation and control groups [32.69% (17/52) vs. 20.69% (12/58), P > 0.05]. There was no significant difference in recurrence of stage I NSCLC between the observation and control groups [3.85% (2/52) vs. 1.72% (1/58), P = 0.495]. Conclusion:The overall effect and safety of thoracoscopic segmentectomy of complex lung segment in the treatment of stage I NSCLC are comparable to those of thoracoscopic segmentectomy of the dominant lung segment. However, thoracoscopic segmentectomy of complex lung segments can reduce the impact on lung function and protect lung function to the maximum extent.

【Objective】 To explore the influence of anti-HLA-Ⅰ with different mean fluorescence intensity (MFI) on the efficacy of HLA-A and -B gene matching platelet transfusion, so as to provide scientific data for clinical platelet gene matching transfusion strategy. 【Methods】 A total of 81 PTR patients had applied for HLA-Ⅰgene matched platelets from the platelet gene database established by our laboratory, and 28 (MFI <5 000) of them needed further avoiding of partial donor-specific antibodies and they were enrolled as the research subjects. According to the platelet MFI value of HLA-Ⅰ antibody-targeting antigen, they were divided into negative transfusion group (MFI <500) (group A) and positive transfusion groups (MFI≥500) ; the latter were further divided into group B (500≤MFI <1 000), group C (1 000≤MFI <3 000) and group D (MFI≥3 000) according to MFI value. Corrected count increment (CCI) in platelet count was used to compare the platelet transfusion effect in 4 groups. 【Results】 Among 28 platelet recipients with MFI <5 000, 19(67.86%) patients successfully received 72 effective transfusions. The first CCI (×10⁹/L) in groups A, B, C and D were 10.27±7.46, 7.58±4.75 (P>0.05), 17.36±7.63 (P>0.05) and -0.77±2.30 (P<0.05), respectively. There was no statistical difference among group A, B and C. 【Conclusion】 The application of HLA-Ⅰ gene matching platelets in PTR patients can adjust the MFI threshold(<2 000) appropriately according to the patient′s condition without compromising the platelet transfusion effect.

【Objective】 To construct a platelet digital matching information system (PMIS). 【Methods】 The framework of PMIS was designed and the main functions were developed. The information system was connected with the information modules of clinical application, laboratory testing, blood donation service, blood inventory and distribution. Further, the preliminary application of this system will be carried on in clinical. 【Results】 The PMIS had been successfully developed and 5048 blood donors with HLA and HPA genotypes were registered in the system. A total of 306 patients applied for matching and 16.5% of them received compatible platelet reports immediately from the inventory bloods, with the median waiting time of all matching as 3 days, which was significantly shorter than that of the manual method (3.8±3.1 days vs 5.4±5.4 days). 【Conclusion】 The developed PMIS has realized the whole process management of blood donors and patients, which is helpful to improve the platelet matching level.

【Objective】 To analyze the specificity and Eplets of HLA allele-specific antibody in patients with platelet transfusion refractoriness (PTR). 【Methods】 HLA-A and B genotypes were detected by PCR-SBT, and HLA-Ⅰ antibodies in patients′ serum were detected by Luminex single antigen beads coating method. IPD-IMGT/HLA Database was used to find the differential amino acids of allele-specific antibodies, and HLA Eplet database was used to analyze the registry Eplets. 【Results】 HLA allele-specific antibodies were found in 12 out of 82 patients with PTR.After sequence alignment, a total of 18 differential amino acids were found, such as 19E>19K, 166D>116E, 167G>167W and so on. Among these differential amino acids, 16 registry Eplets were retrieved such as 19E>19K, 95I>95L, 113YD>113HD and so on.The amino acid substitution of 166DG>166EW, 70Q>70H, 67S>67Y, 94I>94T, 82LR>82RG, and 211G>211A may form new Eplets that have not been registered.The antigens of A11, A24, B15, B27 and B38 can be further subdivided into HLA narrow specific antigens. 【Conclusion】 It was found that there were HLA allele-specific antibodies in patients with PTR, suggesting that high-resolution typing of HLA-A, B should be carried out for these patients and platelet donors in HLA compatible transfusion of PTR.

Objective: To investigate the awareness of Internet based sex education and associated among middle school students, and to provide scientific basis to improve sex education using online resources. Methods: By using stratified cluster random sampling method, 449 students from 8 middle schools in Zhejiang Province were investigated with a self designed questionnaire by Chi square test, Logistic regression, and Importance Performance Analysis (IPA). Results: The awareness of Internet based sex education was 66.59%(299), among which 17.15%(77) chose "WeChat", 7.35%(33) chose "sex education website", and 42.09%(189) chose"video platform" as the primary resources of online sex education, respectively. In the sexual health literacy of middle school students, the correct rate in sexual safety and sexual assault was higher than 40%, with STD transmission and prevention higher than 70%. The correct rate was more than 80% when it came to sexual physiology and sexual development. Logistic regression analysis showed that higher score of sexual health literacy was associated with higher awareness of Internet based sex education ( OR =1.06, 95% CI =1.01-1.11, P <0.05). According to the IPA, the teaching effect and content in area A (the dominant area) had higher scores of importance and satisfaction.The funniness of content in area B (retention area) had a lower importance score and a higher satisfaction score. The practicality and interactivity in area C (opportunity area) had low scores of importance and satisfaction. The curriculum model in area D (improvement area) scored higher in importance and lower in satisfaction. Conclusion The awareness of Internet based sex education needs to be improved among middle school students. Efforts should be made to improve sexual health literacy. Online platforms providing sex education should focus on improving the relevant course model, strengthening the practicability and interactivity of the course, and continue to maintain the advantage of teaching effect, teaching content and interesting aspects of the course.
