OBJECTIVE:To observe the clinical efficacy and safety of triple therapy of aspirin,clopidogrel and urinary kallidi-nogenase in the treatment of recurrent transient ischemic attack. METHODS:180 patients with recurrent transient ischemic attack were randomly divided into control group and observation group. Control group was orally treated with Aspirin enteric-coated tab-lets 100 mg,once a day + Clopidogrel hydrogen sulfate tablets 75 mg,once a day. Based on the treatment of control group,obser-vation group was additionally treated with Urinary kallidinogenase for injection 0.15 PNA unit adding into Sodium chloride injec-tion 100 ml by intravenous injection,once a day. The treatment course for both groups was 2 weeks. The clinic data was observed, including clinical efficacy,and LDL,HDL TC and TG levels before and after treatment,recurrence rate of cerebral ischemia,inci-dence of cerebral infarction and adverse reactions after 6 months of follow-up. RESULTS:The total effective rate in observation group was significantly higher than control group,and the recurrence rate of cerebral ischemia and incidence of cerebral infarction were significantly lower than control group(P<0.05). After treatment,HDL level in 2 groups were significantly higher than be-fore,and observation group was higher than control group;levels of LDL,TC and TG were significantly lower than before,and observation group was lower than control group(P<0.05). There were no severe adverse reactions in groups during treatment. CON-CLUSIONS:Triple therapy of aspirin,clopidogrel and urinary kallidinogenase has significant efficacy in the treatment of transient ischemic attack,with good safety.

Objective To develop a tool capable of early and exactly predicting various outcomes in comatose survivors who restore spontaneous circulation after cardiopulmonary resuscitation (CPR) and validate its performance.Methods Variables that were both readily available and predictive of outcomes were identified by systematically reviewing published literature on resuscitation.A value was assigned to these variables.We used these variables in combination with APACHE Ⅱ/score to devise a multifactorial prediction score system,which we called PRCSs Prognostication Score (PRCSs-PS).Outcomes in 115 hospitalized comatose survivors after CPR were retrospectively reviewed using PRCSs-PS.Score of patients with different outcomes was compared.The area under the receiveroperating characteristic (ROC) curve was determined to evaluate performance of this tool to identify patients with a poor outcome (CPC4 and 5) and other outcomes (CPC1,2,and 3).Results There were differences of PRCSs-PS score among multiple groups with five different outcomes (CPC1-5)(F=65.91,P=0.000).Pairwise groups with different CPC were compared:no significant difference was noted between CPC 1 and CPC2 (12.41±6.49 vs 17.38±6.91,P=0.092),but difference between other pairwise CPC groups was statistically significant (CPC2 vs CPC3:17.38±6.91 vs 24.50±5.80,P=0.041,CPC3 vs CPC4:24.50±5.80 vs 32.29±5.24,P=0.006).The performance of PRCSs-PS to discriminate patients with a poor outcome from patients with other outcomes went as follows:it had 100% sensitivity,78.6% specificity,and 178.6 diagnostic index at the score cut-off22.5; it had 77.8% sensitivity,100% specificity and 176.4 diagnostic index at the score cut-off32.5.Score 23 and 33 were two key cut-offpoints.The area under the ROC curve was 0.968,showing excellent discrimination.Conclusions The final outcomes in post-resuscitation comatose survivors can be accurately predicted using PRCSs-PS Score.

Objective: To detect WNT10A gene mutations in patients with oligodontia or anodontia (≥6 teeth missing) and analyze their dental phenotype. Methods: Patients with oligodontia or anodontia were enrolled from the clinic for oral examination, genetic history collection and whole exon sequencing, and patients with WNT10A gene mutations were included. Sanger sequencing was utilized to validate the WNT10A gene variations in probands and family members compared with the normal sequence. The pathogenicity of WNT10A mutations was evaluated by functional prediction, conservation analysis and structure prediction of protein mutants. Implant rehabilitation was applied to restore the patients' oral function. Results: Five WNT10A gene mutations were detected in six unrelated patients, and c.26G>A (p. Trp9X) and c.1036delT (p. Cys346fs) were novel mutations with pathogenic potential. The mean number of missing teeth was (15.33±8.64) per case. The most frequently missing permanent teeth were maxillary canines (100%), and the least frequently missing teeth were mandibular first molars (25%). Implant rehabilitation was applied in five patients, and patients were found to have ideal implant osseointegration and functional restoration. Conclusion This study identified novel WNT10A gene pathogenic variants, enriching the WNT10A gene spectrum and providing new evidence for genetic diagnosis and prenatal consultation. Implant rehabilitation was also proven to be a treatment option for these patients.
