OBJECTIVETo evaluate the adjunctive effect of diode laser irradiation for the treatment of periodontal-endodontic combined lesions.

METHODS30 cases with periodontal-endodontic combined lesions were selected. All cases were randomly divided into experimental group and control group (n=15). In the control group, patients were treated with root canal therapy and conservative periodontal treatment (scaling and root planning), and patients in the experimental group were treated with root canal therapy and conservative periodontal treatment followed by diode laser irradiation. Clinical measurements including pocket probing depth (PPD), clinical attachment level (CAL), modified bleeding index (mBI), periapical index (PAI) were taken before treatment (baseline). Three and six months after the treatment, the adjunctive effects of diode laser in the treatment of periodontal-endodontic combined lesions were evaluated.

RESULTSThree months after the treatment, the average PPD, CAL and mBI levels were reduced significantly in both groups. But the average PPD reduction in the experimental group was significantly greater (P<0.05) than in control group. However the average CAL and mBI reduction were not significantly different between two groups. Six months after the treatment, the average PPD, CAL and mBI levels were further reduced in the experiment group, but not in the control group. The average PAI levels were reduced significantly in both groups, but the PAI reduction was not significantly different between two groups.

CONCLUSIONThe use of diode laser as an adjunct procedure in the treatment of periodontal-endodontic combined lesions can aid in achieving success.

Objective:To establish a scientific and standardized routine for perioperative nursing in pediatric otolaryngology, reduce the incidence of postoperative delirium, and improve the quality of postoperative recovery by implementing the best practice of evaluation and intervention of postoperative delirium in pediatric otolaryngology.Methods:By reviewing literature related to evaluation, prevention, intervention and management of postoperative delirium in pediatric otolaryngology from March 2018 to September 2019, fourteen best practice were concluded. By combining the best evidence and the clinical circumstances, the evidenced-based criteria were established and then applied in the Otolaryngology and Head and Neck Surgery Department, the Children ′s Hospital of Zhejiang University School of Medicine. Results:After three rounds of reviews, the results showed that the criteria 2, 3, 6, and 8 had 100.0% complacence. Comparison of before and after applying the evidence, there was no statistically significant difference for the occurrence of postoperative delirium or pain ( P>0.05); there was a statistically significant reduction of pain score at 60 minutes after returning to the ward ( χ2=9.93, P<0.05); there was a statistically significant reduction of preoperative anxiety score of children ′s family members from (33.36 ± 6.84) points to (29.54 ± 6.94) points ( F=6.33, P<0.05); there was a statistically significant increase of doctors ′ score of delirium knowledge based on evidence from (23.00 ± 3.94) points to (33.43 ± 8.25) points ( t=-3.02, P<0.05); and there was a statistically significant increase of nurses ′ score of delirium knowledge based on evidence from (33.11 ± 8.46) points to (57.79 ± 6.58) points ( t=-10.35, P<0.05) when the evidence was applied. Conclusion:The evidence-based practice didn ′t significantly relieve the postoperative delirium in pediatric otolaryngology, but it was helpful to relieve the postoperative pain level of children and the anxiety level of their families. The management of postoperative delirium in pediatric otolaryngology needs to be further explored.

Objective:To identify the genetic variation in a mucopolysaccharidosis type Ⅱ(MPS Ⅱ)family, and conduct a functional study of iduronate-2-sulfatase(IDS): c.323A>C.Methods:A five-generation MPS Ⅱ family of 83 individuals including 4 patients from northern China was collected. Urine mucopolysaccharide and Alder-Reilly body were tested to assist the clinical diagnosis of MPS Ⅱ. IDS enzyme activity was detected on core family members. By the whole exome sequencing of a MPS Ⅱ patient in this family and bioinformatics analysis, the variant was screened and further identified by PCR-Sanger sequencing. Finally, to validate the function of the variant in vitro, the wild-type IDS overexpression plasmid(pCMV-hIDS-WT)and the IDS overexpression plasmid carrying the mutation site(pCMV-hIDS-c.323A>C)were transfected into COS-7 cells and the IDS activity was detected. Results:The proband(Ⅳ3)and Ⅳ4 were diagnosed as MPS Ⅱ by urine mucopolysaccharide, Alder-Reilly body, and IDS enzyme activity tests. Ⅳ3, Ⅳ4, Ⅲ19, and Ⅲ32 were determined to carry IDS: c.323A>C missense variant through the whole-exome sequencing, and diagnosed as MPS Ⅱ. Meanwhile, Ⅱ2, Ⅱ4, Ⅱ8, Ⅱ12, Ⅱ14, Ⅲ5, Ⅲ7, Ⅳ14 in the MPS Ⅱ family carried IDS: c.323A>C missense variant, and were excluded as MPS Ⅱ. The in vitro experiment in COS-7 cells showed that the missense mutation led to a significant decrease in IDS enzyme activity. Conclusion:The variant IDS: c.323A>C: p.Y108S significantly decreases the activity of IDS enzyme in vivo and in vitro, and it is identified as a pathogenic variant for MPS Ⅱ.

BACKGROUND: Red-cell transfusion is critical for surgery during the peri-operative period; however, the transfusion threshold remains controversial mainly owing to the diversity among patients. The patient's medical status should be evaluated before making a transfusion decision. Herein, we developed an individualized transfusion strategy using the West-China-Liu's Score based on the physiology of oxygen delivery/consumption balance and designed an open-label, multicenter, randomized clinical trial to verify whether it reduced red cell requirement as compared with that associated with restrictive and liberal strategies safely and effectively, providing valid evidence for peri-operative transfusion. METHODS: Patients aged >14 years undergoing elective non-cardiac surgery with estimated blood loss > 1000 mL or 20% blood volume and hemoglobin concentration <10 g/dL were randomly assigned to an individualized strategy, a restrictive strategy following China's guideline or a liberal strategy with a transfusion threshold of hemoglobin concentration <9.5 g/dL. We evaluated two primary outcomes: the proportion of patients who received red blood cells (superiority test) and a composite of in-hospital complications and all-cause mortality by day 30 (non-inferiority test). RESULTS: We enrolled 1182 patients: 379, 419, and 384 received individualized, restrictive, and liberal strategies, respectively. Approximately 30.6% (116/379) of patients in the individualized strategy received a red-cell transfusion, less than 62.5% (262/419) in the restrictive strategy (absolute risk difference, 31.92%; 97.5% confidence interval [CI]: 24.42-39.42%; odds ratio, 3.78%; 97.5% CI: 2.70-5.30%; P <0.001), and 89.8% (345/384) in the liberal strategy (absolute risk difference, 59.24%; 97.5% CI: 52.91-65.57%; odds ratio, 20.06; 97.5% CI: 12.74-31.57; P <0.001). No statistically significant differences were found in the composite of in-hospital complications and mortality by day 30 among the three strategies. CONCLUSION: The individualized red-cell transfusion strategy using the West-China-Liu's Score reduced red-cell transfusion without increasing in-hospital complications and mortality by day 30 when compared with restrictive and liberal strategies in elective non-cardiac surgeries.
