Objective To prove the necessity of precise red blood cell transfusion by studying the frequency of double population of Rh blood group C and E antigen after allogeneic red blood cell transfusion in our hospital and its influence on blood transfusion efficacy. Methods From June 2021 to March 2022, 296 blood recipients, transfused with ABO homogeneous but RhC/E phenotypes unknown 2U-RBC suspension, were enrolled from Beijing Jishuitan Hospital, and the ABO, RhD, RhC, RhE blood type before transfusion and double population frequency of C and E antigens after transfusion were detected. Patients with RhC and E not changed in comparison with pre-transfusion were set as group A(n=135), with RhC becoming double population as group B (n=18), with RhE becoming double population as group C (n=116), and with both RhC and RhE changed to double population as group D(n=27). The levels of red blood cell (RBC), haemoglobin (Hb) and hematocrit (HCT) before and after blood transfusion were compared among the four groups. Results The negative rates of RhD, RhC and RhE in 296 patients were 0.34%(1/296), 20.27%(60/296) and 67.57%(200/296), respectively. There were 17 cases out of positive screening for unexpected antibodies, among which 7 cases were of anti-E, with the highest proportion. After RBCs transfusion, the double population frequencies of C and E antigens were 15.20%(45/296) and 48.31%(143/296), respectively. The levels of RBC, Hb and HCT in group A, B, C and D were significantly increased, and the difference was statistically significant (P<0.05). There were significant differences in the elevations of RBC and HCT among the four groups (P<0.05), and the elevations of RBC, Hb and HCT were all group A > group C > group B> group D. Conclusion The Rh blood group C and E antigen double population has an significant influence on the efficacy of blood transfusion.

OBJECTIVE:Calibrated Automated Thrombogram(CAT) is a test to monitor the generation of thrombin. It can be described by four parameters: lag time, peak thrombin, endogenous thrombin potential (ETP) and time to peak (ttPeak). This study aims to determine the normal ranges of CAT parameters in Chinese, and evaluate whether thrombin generation is correlated with the concentration of heparin/low molecular weight heparin.METHODS:Plasma from 120 healthy subjects were collected to determine the normal rangea of CAT parameters in Chinese. Normal plasma pool (NPP, n=25) spiked with different concentrations of heparin or enoxaparin were used to detecte CAT parameters. The overall and age specific normal ranges of CAT parameters were calculated using descriptive statistics method with mean±2SD. The correlation between CAT parameters and age or concentrations of heparin, enoxaparin were analyzed with linear regression model.RESULTS:The normal ranges for lag time, peak thrombin, ETP, ttPeak in the subjects were 3.648±2.465 min, 367.39±151.93 nmol/L, 2277±1030 nmol/L•min and 6.372±4.280 min respectively. Age was linearly correlated with lag time (r=-0.6583, P<0.0001), peak thrombin (r=0.4863, P<0.0001), ETP (r=0.3608, P<0.0014) and ttPeak (r=-0.6313, P<0.0001). The values of ETP/peak ratio were linearly correlated with concentrations of heparin.CONCLUSION:The normal ranges of four CAT parameters for Chinese were determined. CAT parameters are associated with age. ETP/peak ratio could be used to monitor the process of anticoagulation therapy.
Objective To evaluate the effectiveness of using anti-CCP as the single laboratory parameter for RA diagnosis,versus to use anti-CCP,RF,and other parameters in combination.Material and methods level of RF was measured by rate scattering turbidimetry method;anti-CCP level was measured by ELISA;level of AKA and APF were measured by indirect immunofluorescent assay.Results For diagnosis of RA,there's no significant difference in sensitivity between anti-CCP and RF(P0.05),However,specificity of anti-CCP is significantly higher than RF(P 0.05).Compared to AKA and APF,the sensitivity of anti-CCP measurement is significantly higher(P0.05),with no significant difference in specificity.Compared to using anti-CCP alone,to use both anti-CCP and RF for RA diagnosis, there was no significantly improvement of sensitivity,whereas the specificity dropped significantly.To use anti-CCP in combination with either AKA or APF,there were no significant changes in both the sensitivity and specificity.AntiCCP in combination with RF,with AKA,and with APF,compared to anti-CCP alone,had significantly lower specificity(P0.05).Compared with anti-CCP alone,when anti-CCP measurement was combined with all three other parameters(RF,AKA,and APF),there was no significant difference in specificity,but sensitivity was significantly lower(P 0.05)Conclusion anti-CCP level alone for RA diagnosis is more effective than RF measurement;combination of antiCCP measurement with RF,AKA,and APF did not significantly improve the sensitivity and specificity.We recommend that anti-CCP measurement alone is sufficient and can replace RF measurement for RA diagnosis.
Objective To monitor the distribution of pathogenic bacteria causing wound infection in trauma patients and their susceptibility to antibiotics in an effort to offer evidence for the rational clinical use of antibiotics.Methods Pathogens were identified by expressive type,but a very few was determined by the molecular methods.Micro-dilution or Kirby-Bauer method for minimum inhibitory concentration (MIC) was adopted for drug susceptibility test.Results A total of 121 species of pathogens numbering 1,257 bacterial strains were isolated from 1,066 patients.Strain number of the top 10 species accounted for 70.09%.Gram-positive cocci accounted for 48.93% and Gram-negative bacilli for 49.72%.Among Staphylococcus aureus and epidermidis,methicillin-resistant bacterial strains accounted for 34.76% and 71.08% respectively,but none were resistant to vancomycin or linezolid.Enterococcus faecalis contained 6.06% vancomycin-resistant enterococcal (VRE) and remained > 90% sensitive to teicoplanin,ampicilin and vancomycin.Enterococcus faecium contained 10.53% VRE and remained >90% sensitive to teicoplanin and > 80% sensitive to vancomycin.Baumanii contained 12.77% multidrug resistant strains and remained > 70% sensitive to imipenem and meropenem.Baumanii/calcoaceticus complex contained 29.72% multi-drug resistant strains and remained > 50% sensitive to imipenem and meropenem.Pseudomonas aeruginosa contained 3.73% multi-drug resistant strains and remained >90% sensitive to amikacin,meropenem,imipenem and piperacillin/tazobactam.No E.coli,klebsiella pneumoniae and enterobacter cloacae resistant to imipenem or meropenem were found.E.coli contained 69.51% extended-spectrum β-lactamases (ESBLs)-producing strains and remained > 90% sensitive to piperacillin/tazobactam and > 80% sensitive to amikacin.Klebsiella pneumoniae contained 53.13% ESBLs-producing strains and remained > 80% sensitive to amikacin.Conclusions Common bacteria are the leading cause of posttraumatic infection.Enterococcus faecalis and enterococcus faecium demonstrate higher susceptibility to teicoplanin; two kinds of acinetobacter demonstrate higher susceptibility to imipenem.
