ABSTRACT
Objective:To investigate the effectiveness and advantage of visual laryngoscope in the treatment of patients with sudden cardiac arrest who need spontaneous respiration tracheal intubation.Methods:Totally 60 patients who suffered from cardiac arrest and needed spontaneous respiration tracheal intubation were enrolled from June 2020 to February 2021 in the Affilicated Hospital of Chifeng University. Theywere randomlydivided into two groups-traditional laryngoscope (TL) group and visual laryngoscope (VL) group, with30 patients in each group. Then the success rate of glottis exposure, the operative time, success rate and complication rate of tracheal intubation were compared between the two groups. Subgroup assessment between the junior emergency resident doctor (A group) and the senior emergency resident doctor (B group) was conducted.Results:According to Cormack Lehan grades, the success rate of glottis exposure in VL group was higher than that in TL group ( P>0.05), and the success rate of Grade I in VL group was significant higer than that in TL group: 56.70%(17/30) vs. 30.00%(9/30), P<0.05. The trial times of successful intubation cases and the operative time of successful intubation cases were significantly less than those in TL group (1.30 vs 1.67, P = 0.049) and (56.37 s vs 67.12 s, P<0.05). In the subgroup, the one-time success rate of tracheal intubation in A-TL group was significantly lower than that in B-TL group (4/15 vs. 11/15, P<0.05), while the one-time success rate of tracheal intubation in A-VL group was 60.00%, which is lower than that in B-VL group ( P>0.05). The operative time consumed for successful intubation in A-TL group was significantly longer than that in B-TL group: 78.00 s vs. 55.57 s, P<0.05, while the operative time in A-VL group was a little longer than that in B-VL group ( P>0.05). Conclusions:Visual laryngoscope used in spontaneous respiration tracheal intubation can not only increase the success rate of glottis exposure, decrease trial times and shorten operative time of intubation, but also improve the success rate and decrease the complication rate of emergency tracheal intubation.
ABSTRACT
Objective To evaluate the treatment effect of bladder instillation chemotherapy on glandular cystitis. Methods The clinical data of glandular cystitis of 54 cases were retrospectively analyzed, all cases were treated individually and the applications of chemotherapeutic drugs bladder instillation were not adopted. Results Follow-up period ranged from 2.5 to 9.0 years, and the average was 4.6 years. Lower urinary tract symptoms score before treatment, 3 month , 6 month, 2 years , 4 years after treatment was (8.5 ± 3.7), (5.7 ± 2.3), (3.9 ± 1.3), (4.0 ± 1.9), (4.2 ± 1.9) scores, and the scores after treatment were improved significantly compared with that before treatment (P < 0.05). Recurrence rate 3 months , 6 months, 2 years and 4 years after treatment was 3.7％(2/54), 13.0％(7/54), 5.6％(3/54) and 1.9％(1/54). Conclusions Eliminating the inducements and improvement of symptoms provides a significantly curative effect in glandular cystitis. Postoperative bladder instillation chemotherapy is not recommended.
ABSTRACT
Objective@#To investigate the distributions of Candida albicans (Ca), which are closely associated to early childhood caries (ECC) of young children, in 3-5-year-old children of Mongolian, Uygur and Han ethnic groups in Bortala Mongol Autonomous Prefecture of Xinjiang Urgur Autonomous Region, so as to provide scientific basis for the early prediction and prevention of caries locally.@*Methods@#Totally 1 089 healthy children aged 3 to 5 years old (Mongolian 136, Uygur 403 and Han 550; 568 males and 521 females) were randomly selected by stratified and cluster sampling method. The children in early childhood caries group were 786 and in caries free group were 303. Dental plaque samples were collected from the carious tooth tissues and supragingival sites, respectively. Samples were isolated and cultured by different media. Ca were identified by Gram stain, germ tube test, PCR method and internal transcribed spacer region sequencing methods. Ca isolated were further typed by using PCR-25SrDNA genotype method. Pearson χ2 test and Spearman rank correlation were used to analyze the differences in genotypes of Ca amongst three ethnic groups and the relationship between decayed missing filled tooth (dmft) classification and detection of Ca.@*Results@#The Ca was significantly higher in the ECC group [14.4% (113/786)] than in the caries free group [7.6% (23/303)] (P=0.002). The identified rate of Ca in Mongolian group was [11.8% (16/136)], which was significantly lower than that of Uygur group [17.9% (72/403)] and higher than that of Han group [8.7% (48/550)] (χ2=10.192, P=0.006). Among the male children, the identified rate of Ca in Mongolian group was [10.0% (8/80)], which was significantly lower than that of Uygur group [21.7% (44/203)] and higher than that of Han group [8.4% (24/285)] (χ2=18.887, P=0.000). Among the female children, the detection rates of Ca were [14.3% (8/56)] in Mongolian group, [14.0% (28/200)] in Uygur group and [9.1% (24/265)] in Han group. There were no significant differences among the three ethnic groups (χ2=3.206, P=0.201). The identification rates of oral Ca in Uygur and Han ECC groups were correlated with the decayed, missing and filled teeth (Uygur r=0.195, P=0.001; Han r=0.145, P=0.004). Totally 136 Ca samples were divided into 3 types by PCR-25SrDNA method, and the predominant type was type A [55.1% (75/136)].@*Conclusions@#The distribution of oral Ca among children were ethnically different. Uygur male children carrying Ca were more susceptible to dental caries. Ca might be a risk factor for ECC. There was no specific cariogenic genotype in Ca isolated. There were no associations between ethnic factors and the genotypes of Ca isolated.
