Objective:To evaluate the effect of N-acetylcysteine (NAC) in relieving discomfort symptoms after esophageal Lugol′s iodine staining.Methods:From April 1 to September 30, 2023, a total of 204 subjects who received endoscopy at the First Affiliated Hospital of Shihezi University were enrolled. All the subjects were stained with 10 mL 1.5% compound iodine solution after endoscopy. According to random number table method, the 204 subjects were randomly divided into two groups which received 20 mL 0.9% sodium chloride solution (sodium chloride group, 103 cases) and 10% NAC (NAC group, 101 cases) to neutralize the iodine, respectively. The primary outcome indicators of the subjects of the two groups were analyzed, including the incidence of retrosternal burning sensation and pharyngeal discomfort 15 and 30 min after spraying the neutralization solution, and the degree of discomfort was evaluated by visual analogue scale (VAS). Fisher′s exact probability method and non-parametric test were used for statistical analysis.Results:The incidence of retrosternal burning sensation and pharyngeal discomfort 15 and 30 min after spraying the neutralization solution in the sodium chloride group were higher than those in the NAC group (15 min: 17.5% (18/103) vs. 2.0% (2/101), 10.7% (11/103) vs. 1.0% (1/101); 30 min: 11.7%(12/103) vs. 1.0% (1/101), and 5.8% (6/103) vs. 0 (0/101)), and the differences were statistically significant (Fisher′s exact probability method, P<0.001, =0.005, =0.003, and =0.029). There was no significant difference in the VAS score 15 min after spraying neutralization solution between the sodium chloride group and the NAC group (3.00 (3.00, 4.25) vs. 4.00 (3.00, 5.25), P>0.05). At 30 min after spraying the neutralization solution, the VAS score of the sodium chloride group was higher than that of the NAC group (4.00(3.75, 5.00) vs. 1.50(1.00, 1.50)), and the difference was statistically significant ( Z=-2.37, P=0.007). Conclusion:NAC can effectively relieve the discomfort caused by esophageal iodine staining.

Objective:To see the influence of different antiplatelet therapies on stroke patients’ readmission by performing a deep data-mining into Beijing Healthcare Insuring Database,based on a large sample size.Methods:Aretrospective cohort study,was adopted to extract patients primarily diag-nosed as ischemic stroke from healthcare database.The first hospital records were considered as the pa-tient’s baseline in this study,who were divided into MAPT (aspirin)and DAPT (aspirin and clopi-dogrel)according to the patient’s baseline medications.A follow-up was conducted to see whether the patients would have rehospitalization record because of major result events after medication.The major re-sult events,included:(1 )recurrence of ischemic stroke;(2)hemorrhagic transformation of ischemic stroke;(3)myocardial infarction;(4)the digestive hemorrhage.The Kaplan-Meier figure was used to compare the survival situations between these two groups,the log-rank test was used to test the difference of the survival curve,and 1 ∶1 propensity score matching was calculated from the patients’baseline da-ta.Cox proportional hazards model was used to calculate the hazard ratio (HR).Results:A total of 27 695 patients From January 201 0 to September 201 3 were included,4 047 with DAPT,and 23 648 with MAPT.Because the baseline characteristics of the patients was disequilibrium,so we used 1 ∶1 pro-pensity score matching,after which,the number of the two groups was 4 046 each.Adjusted for the gen-eral demographic characteristics such as age,sex,nationality,complication and drug combination,no statistical significance was observed between the survival curves of the two groups (P =0.06).HR value of major result events between the groups was 0.91 (0.82 -1 .01 ,P =0.07),which was not statistically significant.The covariate gender HR =1 .36 (1 .20 -1 .55,P <0.05),accompanied by diabetes HR =1 .36 (1 .20 -1 .54,P <0.05 ),dyslipidemia HR =1 .1 3 (1 .00 -1 .27,P =1 .1 3),heart disease HR =1 .39 (1 .22 -1 .58,P <0.05)was statistically significant.Drug combination with other antiplate-let agents HR =1 .05 (0.95 -1 .1 7,P >1 .05)did not increase the risk of readmission.Conclusion:There was no difference in prevention of readmission between patients with DAPT and MAPT.Patients with complications should actively treat the complications at the same time as they prevent recurrence after first attack.

BACKGROUND:Pierre Robin Sequence is a congenital malformation which is characterized by micrognathia, glossoptosis and respiratory tract obstruction with or without cleft palate. SOX9, KCNJ2, Ptprs and Ptprf are probably connected with Pierre Robin Sequence. OBJECTIVE:To review the recent progress in the researches on the related genes about Pierre Robin Sequence. METHODS:A computer-based online search of CNKI database and PubMed database was performed to retrieve the relevant articles published from January 1999 to September 2014 with the key words of“micrognathia, Pierre Robin Sequence, mutation, gene locus”in Chinese and English, respectively. Final y, 58 articles were included for review after deleting unrelated and repetitive ones. RESULTS AND CONCLUSION:SOX9, KCNJ2, Ptprs and Ptprf are probably connected with Pierre Robin Sequence. Recently, the research on the genes connected with Pierre Robin Sequence focuses on 17q23-24, and smal sample cases are commonly seen. But, further large sample test and case analysis, as wel as related animal models are needed to analyze the role of these genes in the pathogenesis of Pierre Robin sequence, as wel as consequently, we can analyze the etiology and pathogenesis of Pierre Robin sequence.
