【Objective】 To compare the effects of 3 rehydration methods before blood donation on the prevention of on-site and delayed blood donation-related vasovagal response (VVR) . 【Methods】 From January to June 2021, 6 250 whole blood donors in 6 fixed blood donation sites signed informed consent and were divided into 198 clusters according to donor sites and dates, then they were randomly assigned to receive either oral rehydration salts (ORS), sugar water, or water group, and each drank 500 mL of ORS, sugar water or water within 20 minutes before blood donation. The researchers recorded the actual intervention accepted on site, and recorded the immediate VVR and related information. At rest after blood donation, donors submitted an electronic questionnaire containing socio-demographic information. At 48 hours after blood donation, the researchers called back every donor to record delayed VVR and related information. Logistic regression based on intention to treat (ITT) was used to analyze the difference of the incidence of VVR among the three groups, and the average treatment effect on treated (ATT) was calculated. PASS 2021was used to estimate the sample size and R (4.2.0) for statistical analysis. 【Results】 The cumulative incidence of blood donation-related VVR was 2.67% (2.29%-3.11%) among street whole blood donors under the 3 rehydration methods, in which, the incidence of immediate and delayed VVR was 1.02% (0.79%-1.31%) and 1.65% (1.36%-2.01%) respectively. ITT analysis found that ORS were more effective than water in reducing the incidence of delayed VVR【OR=0.59,95% CI[0.37,0.94]】.There was no significant difference in the incidence of immediate VVR between any two groups (P > 0.05), and there was no significant difference in the incidence of delayed VVR in the sugar water group compared with the water group (P > 0.05). There was a difference of -0.013 (【95% CI[-0.022, -0.004]】or -0.008【95% CI[-0.017, -0.000]】in the incidence of delayed VVR in the ORS group compared with water group or sugar water group, the difference was significant (P<0.05). The cumulative VVR of the three groups showed similar results to the delayed VVR. 【Conclusion】 Drinking ORS before blood donation is the most effective rehydration method to prevent delayed VVR. The next step is to establish the predictive model of delayed VVR to screen the susceptible population and provide them with ORS before blood donation, while other population can choose any liquid they like, thus achieving personalized blood donation-related VVR prevention and control.

[Objective] To explore the characteristics of lifestyle behaviors and mental health status among blood donors in Guangzhou, and to investigate the correlation between donation frequency and these factors. [Methods] A cross-sectional study was conducted among 13 042 whole blood donors from 17 street blood donation sites of Guangzhou Blood Center from May to August 2020. Descriptive analysis was used to describe the characteristics of lifestyle behaviors and mental health status among blood donors in Guangzhou. Ordinal multinomial logistic regression model was used to analyze the correlation between donation frequency and these factors. [Results] It was found that some of 13 042 blood donors had unhealthy habits, such as 6.8% (698/10 214，2 828 missing values) had severe tobacco dependence, 30.6% (3 997/13 042) had low exercise levels, 38.8%（5 056/13 042）had poor sleep quality, and 2.2% (271/12 159，883 missing values) had alcohol dependence. In addition, 2.8% (364/13 042) and 1.3% (172/13 042) of the donors may have moderate to severe depression and anxiety symptoms, respectively. The results of the ordinal multinomial logistic regression model showed that exercise level was significantly negatively correlated with the degree of depression and anxiety among blood donors. With the decrease in exercise level, the possibility of depression and anxiety among donors increased significantly. BMI, household income, education level, marital status, donation frequency, alcohol consumption and smoking had no significant correlation with the mental health status of donors. [Conclusion] Improving the exercise habits of blood donors may help enhance their mental health level. It is recommended that blood station staff strengthen the content of exercise when providing health education to blood donors to maintain a healthy lifestyle. It also suggests that there may be a certain degree of under-diagnosis of mental health problems in the process of health consultation before blood donation, and conducting more comprehensive and effective mental health assessments for blood donors is recommended.

Objective To compare the differences in lower limb force line between degenerative medial meniscus injuries and lateral meniscus injuries and investigate their correlation.Methods A total of 90 patients who underwent arthroscopic treatment for meniscal injuries between March 2019 and March 2022 were enrolled in the study.They were 45 males and 45 females,at a median age of 52 years(ranging from 40 to 59 years).Of these patients,47 had medial meniscus injuries,while 43 had lateral meniscus injuries.The hip-knee-ankle(HKA)angle was measured on full-length films,and the differences were compared between the 2 groups.Results There were no significant differences in terms of gender,age,lower limb laterality,body mass index,site of injury,and type of injury between the medial meniscus injury group and the lateral meniscus injury group.Statistical difference was observed in the mean HKA angle,with a value of(177.20±2.46)° in the medial meniscus injury group and of(181.05±3.13)° in the lateral meniscus injury group(P＜0.01).Conclusion There is a significant difference in HKA angle between medial meniscus injury group and the lateral meniscus injury group.A correlation is found between lower limb alignment and degenerative meniscus injury.

Objective To explore the value of controlling nutritional status(CONUT)score and related inflammatory indicators in predicting the prognosis of clear cell renal cell carcinoma(ccRCC)patients,to provide a reference for better clinical assessment and individualized treatment plan.Methods A retrospective study was conducted on 132 patients with ccRCC admitted to four comprehensive hospitals in Yibin during 2010 and 2018.Patients'medical and follow-up records were collected,and receiver operating characteristic(ROC)curve was drawn to analyze the area under the curve(AUC)and optimal cut-off value of CONUT score and related indicators.Survival curve was plotted with Kaplan-Meier method,and the influencing factors of prognosis were analyzed with Log-rank test and Cox regression.Results During the follow-up of 62(53,71)months,37(28.03％)deaths occurred.The disease-specific survival(DSS)and progression-free survival(PFS)were 51(41,58)and 46(35,56)months,respectively.The 3-year and 5-year DSS and PFS were 84.09％and 71.97％,and 75.00％and 71.97％,respectively.The AUC of CONUT score,neutrophil to lymphocyte ratio(NLR),platelet to lymphocyte ratio(PLR),and lymphocyte to monocyte ratio(LMR)were 0.980,0.905,0.899 and 0.884,respectively,with the optimal cut-off values of 3.50,3.19,89.07 and 3.56,respectively.Cox regression showed that CONUT score(HR=0.042,95％CI:0.013-0.140)and PLR(HR=0.182,95％CI:0.045-0.744)were associated with DSS;CONUT score(HR=0.029,95％CI:0.010-0.086)and LMR(HR=2.984,95％CI:1.227-7.258)were associated with PFS.Conclusion The prognosis of ccRCC patients is related to their nutritional,immune,and inflammatory status.CONUT score and inflammatory factors(PLR,LMR)may be important predictors of DSS and PFS.

An analytical method based on ultra high performance liquid chromatography-high resolution tandem mass spectrometry(UHPLC-HRMS/MS)and high performance liquid chromatography-triple quadrupole mass spectrometry(HPLC-TQ MS)was established to reveal the characteristics of various sulfur mustard analogs with different active thiol molecules in CWC Schedule 1.A.04.Firstly,the toxic agents were prepared by micro-directed synthesis,and then the differences of the reactivity and abundance of formed adducts between different sulfur mustards and glutathione(GSH),cysteine(Cys)and N-acetylcysteine(NAC)in incubation solution,plasma and cell were investigated,respectively.The results indicated that all target sulfur mustards could react with three kinds of thiol molecules.The content of Cys and sulfur mustard adducts in plasma was higher than that of GSH and sulfur mustard adducts,while NAC and sulfur mustard adducts might have fewer types of adducts due to low content or poor mass spectrometry response.Additionally,the content of GSH and sulfur mustard adducts in exposed cells was higher than that of Cys,which should be due to the significant difference in the content of thiol molecules in plasma and cells.

Objective To explore the clinical value of endoscopic ultrasonography(EUS)combined with serum serine protease inhibitor Kazal 1(SPINK1)and secretory phosphoprotein 1(SPP1)in early diagnosis of esophageal cancer.Methods 276 patients from June 2021 to May 2023 were selected as the study objects.92 cases of esophageal cancer diagnosed by operation and pathology were esophageal cancer group,another 89 patients diagnosed as benign esophageal lesions through tissue biopsy were selected as the benign lesion group,and 95 healthy individuals who underwent physical examinations were collected as the healthy control group,general information such as age and gender of subjects in three groups were collected and organized;using pathological results as the gold standard,the accuracy of EUS in diagnosing esophageal cancer was verified;the expression of serum SPINK1 and SPP1 was compared among the esophageal cancer group,benign lesion group,and healthy control group;the relationship between the expression of serum SPINK1 and SPP1 in esophageal cancer patients and their clinical and pathological characteristics was explored;efficacy of EUS combined with serum SPINK1,SPP1 levels for early diagnosis of esophageal cancer was analyzed using receiver operator characteristic curve(ROC curve).Results Compared with the gold standard,the results of EUS examination showed that 81 cases were diagnosed with esophageal cancer,79 cases were diagnosed with benign lesions,11 cases were missed diagnosed,and 10 cases were misdiagnosed,with an accuracy rate of 88.40%(160/181);Compared with the healthy control group and the benign lesion group,the expression levels of serum SPINK1 and SPP1 in the esophageal cancer group were obviously increased,the expression levels of serum SPINK1 and SPP1 in the benign lesion group were significantly higher than those in the healthy control group,the differences were statistically significant(P<0.05);Serum SPINK1 expression was linked to tumor diameter>2 cm,presence of lymph node metastasis,lymph node positivity,and tissue grading level 3 in patients(P<0.05).Serum SPP1 expression level was related to tumor diameter>2 cm,presence of lymph node metastasis,lymph node positivity,and estrogen receptor positivity of patients(P<0.05);ROC curve showed that the area under the curve(AUC)of EUS,serum SPINK1,SPP1 levels,and their combination in the early diagnosis of esophageal cancer was 0.862,0.834,0.782,and 0.926,respectively,the clinical efficacy of the combination of the three in the early diagnosis of esophageal cancer was superior to that of EUS,serum SPINK1,and SPP1 alone(Z=2.30,Z=3.70,Z=4.23,P=0.022,P=0.000,P=0.000).Conclusion The expression levels of serum SPINK1 and SPP1 in esophageal cancer patients are abnormally up-regulated.The combination of EUS and serum SPINK1 and SPP1 has high clinical value in early diagnosis of esophageal cancer.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

ObjectiveTo explore the effects of body weight and waist circumference on static and dynamic balance function in overweight and obese adults. MethodsParticipants （n=103） were selected by cluster random sampling from the Hypoglycemic Weight Loss Clinic of the Endocrinology Department of the Third Affiliated Hospital of Sun Yat-sen University. All participants were assessed for basic data collection， biochemical test， body weight， waist circumference and height measurement， static balance function assessed by balance error scoring system （BESS） and dynamic balance function assessed by functional reach test （FRT）. The BESS score and FRT distance of all participants were compared among groups according to different BMI grades and WC grades. Multivariate linear regression was used to analyze the influencing factors of participants' dynamic and static balance functions. Results① With the increase of BMI grading， the BESS score showed an upward trend， and the difference between groups was statistically significant （P = 0.004）. The BESS score of normal WC patients was lower than that of central obesity patients （P < 0.001）， which indicated that compared with normal BMI， overweight and obese people had poor dynamic and static balance ability； ② With the BMI grading， the FRT distance increased， showing a downward trend （P < 0.001）. The FRT distance in normal WC patients was significantly higher than that in central obesity patients （P < 0.001）， which indicated that the static and dynamic balance ability of central obesity patients was worse than that of normal WC patients； ③ In BMI overweight group， the FRT distance decreased significantly with the increase of WC （P = 0.02）. The results showed that under the condition of no difference in BMI， Compared with normal WC， the dynamic and static balance ability of central obese patients was worse； ④ The influence of BESS score on BMI（B=4.12，P =0.027， 95% CI=0.48-7.75）and WC（B = 3.47，P = 0.046， 95% CI = 0.07 - 6.88）was significant. The influence of FRT distance on BMI（B = -5.68，P = 0.001， 95% CI = -8.95 - 2.41）and WC（B = -4.71，P = 0.003， 95% CI = -7.83 to -1.61）was significant， which indicated that the static and dynamic balance ability of obese people was worse with the increase of BMI， and the ability of dynamic and static balance of central obesity was worse than that of normal WC. ConclusionWaist circumference is an independent factor affecting the dynamic and static balance function of overweight and obese people. Under similar BMI， the dynamic balance function of central obese people is worse than that of people with normal waist circumference， leading to higher risk of falling.

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R² of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.
