Objective To evaluate the transfusion efficacy and safety of patients with non‐specificity irregular antibodies .Meth‐ods A total of 19 cases of patients with non‐specificity irregular antibodies were analyzed ,then the transfusion efficacy and the in‐cidences of adverse transfusion reactions were investigated .Blood donor samples with the same ABO blood type of patients were randomly collected ,then blood cross‐matching was carried out .And the transfusion efficacy and safety of patients with non‐specific‐ity irregular antibody were evaluated when compatible blood were found by using both micro‐column gel technique and saline meth‐od .Results The non‐specificity irregular antibodies of the 19 cases of patients all were IgG irregular antibodies .The erythrocyte transfusion was carried out in the 19 cases of patients ,the total efficiency rate ,partial efficiency rate and inefficiency rate was 73 .7% ,26 .3% and 0 .0% ,respectively .No delayed hemolytic transfusion reactions were observed in any patient .Conclusion For patients with non‐specificity irregular antibodies ,the blood transfusion could be efficacy and safety when compatible blood samples are confirmed by using both micro‐column gel technique and saline method .

Objective To observe the value of ultrasound microvascular flow imaging(MV-Flow)combined with maternal serum vascular endothelial growth factor(VEGF)expression level for diagnosis of fetal growth restriction(FGR).Methods Totally 87 pregnant women with FGR(FGR group,including 43 cases of gestational week<28 weeks[<28 weeks subgroup]and 44 cases of ≥28 weeks[≥28 weeks subgroup])and 112 normal pregnant women with normal fetuses(normal control group,55 with gestational week<28 weeks[NC 1 subgroup]and 57 with ≥28 weeks[NC 2 subgroup])were prospectively enrolled.MV-Flow technology was used to measure placental microvascular index(MVI),and the placental microvascular circulation was evaluated.The expression level of maternal serum VEGF was detected simultaneously,also of placental maternal surface immediately after delivery.The receiver operating characteristic curves were drawn to explore the value of placental MVI,maternal serum VEGF and the combination of placental MVI,maternal serum VEGF for diagnosing FGR.Results The levels of placental MVI and maternal serum VEGF in 2 subgroups of FGR group were both lower than those in control group(all P<0.01).Placental VEGF expression level in FGR group was significantly lower than that in control group(P<0.01).The area under the curve(AUC)of placental MVI,maternal serum VEGF and their combination for diagnosing FGR<28 weeks was 0.981,0.870 and 0.997,respectively,while for diagnosing FGR≥28 weeks was 0.991,0.867 and 0.993,respectively.AUC of maternal serum VEGF alone for diagnosing in 2 subgroups of FGR were both lower than that of placental MVI and combination of placental MVI and maternal serum VEGF(all P<0.05),while no significant difference of AUC was found between placental MVI and combination of maternal serum VEGF and placental MVI(both P>0.05).Conclusion Both placental MVI and maternal serum VEGF level could be used to screen FGR,and the former was more valuable.

Objective:To investigate the changes of mean venous sinus pressure (MVP) and trans-stenosis pressure gradient in patients with idiopathic intracranial hypertension (IIH) under awake setting and general anesthesia.Methods:Thirty-eight patients with IIH accepted venous sinus stent implantation in our hospital from January 2010 to January 2020 were chosen in our study; their clinical data were analyzed retrospectively. The manometry results of these 38 patients were recorded under awake setting and general anesthesia before stenting; MVP and trans-stenosis pressure gradient were obtained and compared.Results:MVP in the superior sagittal sinus, torcular, transverse sinus and sigmoid sinus showed no significant difference between patients under awake setting and general anesthesia ( P>0.05). Mean trans-stenosis pressure gradient in patients under awake setting ([22.784±7.606] mmHg) was significantly higher as compared with that in patients under general anesthesia ([18.388±8.992] mmHg, P<0.05). Conclusion:Mean trans-stenosis pressure gradient in patients under awake setting is higher as compared with that in patients under general anesthesia, and selection for venous sinus stent implantation should be decided by trans-stenosis pressure gradient in patients under awake setting.
