Efficacy of apheresis and concentrated platelets under different transfusion strategies / 中国输血杂志

【Objective】 To retrospectively analyze the clinical effects of apheresis and concentrated platelets under different transfusion strategies, so as to explore more scientific transfusion strategies. 【Methods】 A total of 279 patients with thrombocytopenia, admitted to our hospital during January 2020 and October 2021, were collected.They was divided into group A(apheresis platelet transfusion alone), group B(concentrated platelet transfusion alone), and group C(both apheresis and concentrated platelet transfusion). Platelet count of three groups were measured 24 hours before and after transfusion and their CCI values were calculated and compared to understand the differences in transfusion efficiency and adverse reactions, as well as the efficacy among three groups with different blood groups. 【Results】 Patients, received solo apheresis platelets, demonstrated a lower incidence of transfusion refractoriness and adverse reactions, but also a lower treatment efficacy(14.63±13.48)(P<0.05). However, the treatment efficacy of patients, received solo concentrated apheresis, could reach 16.00±21.77, but presented a higher incidence of transfusion refractoriness and adverse reactions. Patients, received both apheresis and concentrated platelets, maintained a good treatment efficacy(16.21±16.33), with a low incidence of transfusion refractoriness and adverse reactions.At the same time, different blood types also affect the treatment efficacy of platelet transfusion. 【Conclusion】 The simultaneous transfusion of apheresis and concentrated platelets contributes to the effective treatment of patients and lower incidence of adverse reactions.

Analysis of guiding value and effect of TEG in clinical application of cryoprecipitation / 中国输血杂志

【Objective】 To retrospectively analyze the guiding significance and effect of thromboelogram (TEG) in the clinical use of cryoprecipitation. 【Methods】 A total of 289 patients with fibrinogen reduction, admitted to our hospital between January 2018 and December 2021, were collected. They was divided into control group (using coagulation examination and clinical feature as the transfusion criteria) and observation group (above parameters plus TEG). The TEG index in the observation group before and after transfusion and Fg, APTT, PT, and TT in 2 groups of patients before and after transfusion were monitored. The efficacy and prognosis of different blood products and cryoprecipitate were compared between 2 groups of patients.) 【Results】 The efficacy of choprecipitate transfusion was better in the observation group than the control[Fg index after transfusion (g / L) 1.92±0.92 vs 1.80±1.00, P<0.05]. And less blood products were used in observation group as compared with the control[ RBC(U) 1.93±2.69 vs 2.81±3.25 (P<0.05); FFP(mL) 667±378 vs 879±455(P<0.05)]. No differences were noticed by hospital stay between the two groups, but the prognosis in the observed group was significantly better than that in the control. 【Conclusion】 It’s scientific and reasonable to apply TEG to guide the clinical transfusion of cryoprecipitate, so as to save blood resources and improve the prognosis.

Advances in Study on Antibiotic Resistance of Helicobacter pylori / 胃肠病学

Helicobacter pylori (Hp) has been confirmed to be associated with a variety of gastrointestinal tract and extra-gastrointestinal diseases. The eradication rate of classic triple therapy regimen was reduced gradually in recent years, and it was shown that antibiotic resistance and irregular treatment were the main causes of the failure of eradication. The choice of treatment should be based on the local antibiotic resistance situation, if necessary, individual sensitivity tests should be considered. At the same time, the in-depth study on mechanisms of drug resistance is helpful to decrease the eradication failure and reduce the drug resistance. This article reviewed the advances in study on antibiotic resistance of Hp.

Genetic study of a Parkinson's disease pedigree caused by compound heterozygous mutations in PARK2 gene / 中华医学遗传学杂志

OBJECTIVE@#To explore the genetic basis for a Chinese pedigree where three siblings were affected with Parkinson's disease.@*METHODS@#Multiple ligation-dependent probe amplification (MLPA) and next-generation sequencing (NGS) were employed to detect the causative mutation. Sanger sequencing of cDNA was also used for verify the effect of mutation on the transcription of RNA.@*RESULTS@#Heterozygous deletion of exon 3 of the PARK2 gene was detected by MLPA, while a heterozygous splice site variant c.619-3G>C was detected by NGS. Both mutations were shown to result in aberrant transcripts of the PARK2 gene (loss of exons 3 and 6, respectively) by Sanger sequencing of cDNA. Both mutations have co-segregated with the disease in the pedigree.@*CONCLUSION@#Compound heterozygous mutations of the PARK2 gene probably underlie the disease in this pedigree. Identification of the splice site variant c.619-3G>C has expanded the mutation spectrum of the PARK2 gene.

Ultrasonic measurement of humeral distal epiphysial anteverted angulation / 中华超声影像学杂志

Objective To explore the changing regularity of humeral distal epiphysial anteverted angulation with ultrasonic measurement. Methods Using an ultrasonic diagnostic apparatus with a high frequency bougie to detect the dextral elbow joint of 203 normal individuals whose age range is from 5 d to 23 years old. The subjects were divided into 5 groups by age (5 d-4 years old, 5-8 years old, 9-12 years old, 13-16 years old, ≥17 years old),and by sex into two large parts.Anteverted angulation of capitellum and lateral semitrochlear ossification center were measured with statistic analysis and correlation calculation.Results Anteverted angulation of capitellum was 48.89?? 8.96?, lateral semitrochlea 33.70?? 7.18?. Anteverted angulation of capitellum enlarges with age growth, and it reaches the climax ( 55.00?? 5.88?) at the age 13-16 years old. There was a significant difference among groups. After 17 years old, anteverted angulation slightly reduces to 52.38?? 8.27?, compared with the climax ( 55.00?? 5.88?), there was no statistical difference. Changing regularity of anteverted angulation was similar to that of capitellum. Just between the 5 d-4 years old group and 5-8 years old group, the difference was significant in angulation enlargement. There was no statistical difference among the groups above the 5-8 years old group, and no significant difference between male and female in humeral distal epiphysial anteverted angulation. Conclusions Ultrasonic examination can clearly display the images of humeral distal epiphysis. Observation and measurement is available for the epiphysial anteverted angulation by acoustic images, and the changing regularity of anteverted angulation can be illustrated.
