Objective:To investigate the clinical efficacy of root canal filling combined with crown restoration in the treatment of large area defect of deciduous teeth.Methods:The clinical data of 160 children patients with large area defect of deciduous teeth who received treatment in Wenling No.4 People's Hospital from January 2017 to January 2018 were retrospectively analyzed. All included children received root canal filling treatment. According to the different postoperative repair methods, these children were divided into two groups. In the observation group ( n = 80), repair with a prefabricated metal crown was performed. In the control group ( n = 80), resin filling repair was given. Gingival health (gingival index) and restoration effect, including secondary caries, gingival condition (congestion or not) and food impaction were compared between the observation and control groups. Tooth condition (marginal tightness, adjacency) and safety (restoration and abrasion) were compared between the two groups after 1 year of follow up. Results:Before restoration, there was no significant difference in gingival index between the observation and control groups [(0.76 ± 0.41) vs. (0.73 ± 0.32), P > 0.05]. After restoration, gingival index in the observation group was significantly lower than that in the control group [(0.86 ± 0.55) vs. (1.35 ± 0.62), t = 5.288, P < 0.001]. In the observation group, no secondary caries or food impaction was observed, and there was one case of gingival bleeding. In the control group, there were eight cases of secondary caries, four cases of good impaction, and nine cases of gingival bleeding. The incidence of adverse reactions in the observation group was significantly lower than that in the control group ( χ2 = 6.826, P < 0.05). One-year follow-up results revealed that 79 cases (98.75%) were qualified in tooth bonding and 78 cases (97.50%) were qualified in tooth occlusion in the observation group, while 70 cases (87.50%) were qualified in tooth bonding and 69 cases (86.25%) were qualified in the occlusion in the control group. There were significant differences in qualified bonding and occlusion between the two groups ( χ2 = 7.907, 6.781, both P < 0.05). The success rate of marginal tightness, the success rate of adjacency, restoration and abrasion in the observation group were higher or superior to those in the control group (98.75% vs. 86.25%, 100.00% vs. 87.50%, 100.00% vs. 85.00%, 98.75% vs. 83.75%) ( χ2 = 9.009, 10.666, 12.973, 11.272, all P < 0.05). Conclusions:Root canal filling combined with crown restoration in the treatment of large area defect of deciduous teeth has a high success rate of qualified bonding and occlusion, less adverse defects, low incidence of food impaction and gingival bleeding, decreases the risk of secondary caries, protects the remaining tooth tissue, maintains normal chewing function, and is conducive to the eruption of permanent teeth.

Objective To investigate the effect of propofol pretreatment on hypoxia-induced apoptosis of alveolar epithelial type Ⅱ (AE Ⅱ) cells in fetal rats. Methods Primary cultured AE Ⅱ cells isolated from fetal rats were seeded in 96-well plates (1 × 106/L, 180 μl/well) and randomly assigned to one of 3 groups (n = 72each):normal control group (group C), hypoxia group (group H) and propofol-hypoxia group (group P-H).Group H and P-H were exposed to hypoxia (5% O2). In group P-H, propofol (final concentration 5 μ mol/L) was added 1 h prior to hypoxia (5% O2). The apoptotic rate and expression of hypoxia-inducible factor (HIF)-1αmRNA, Bnip3L mRNA, HIF-1α protein and Bnip3L protein were determined at 3, 12, 24 and 48 h of hypoxia.Results The apoptotic rate and expression of HIF-1α mRNA, Bnip3L mRNA, HIF-lα protein and Bnip3L protein were significantly up-regulated in group H compared with group C (P < 0.05). Propofol pretreatment could significantly inhibit the hypoxia-induced changes mentioned above (P < 0.05). Conclusion Propofol pretreatment can inhibit hypoxia-induced apoptosis of AE Ⅱ cells, and the mechanism is related to inhibition of HIF-1αactivation and down-regulation of Bnip3L expression in fetal rats.

Objective To evaluate the serum trough concentration and the pharmacokinetics/pharmacodynamics (PK/PD)of vancomycin in patients with severe acute pancreatitis (SAP), and analyze the effect of vancomycin continuous infusion for optimizing the characteristics of its PK/PD.Methods The inhospital patients with SAP received vancomycin treatment and admitted to emergency intensive care unit (EICU) of Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine from January 2011 to December 2016 were enrolled. Steady-state trough concentrations of vancomycin from patients were collected retrospectively. The SAP patients were divided into augmented renal clearance (ARC) and non-ARC groups, as well as systemic inflammatory response syndrome (SIRS) and non-SIRS groups according to the patients with or without symptom above. Adjustments of increased dosage or 24-hour continuous infusion or increase vancomycin dose were made for patients if the steady-state trough concentrations fell below the target level. Steady state trough concentration for vancomycin intermittent infusion or steady state concentration for vancomycin continuous infusion was determined by the fluorescence polarization immunoassay method. PK parameters of vancomycin were calculated using the Bayesian estimator and the area under the serum drug concentration-time curve (AUCc-t), the minimum inhibitory concentration (MIC) and AUCc-t/MIC was recorded and calculated.Results The steady state trough concentration or steady state concentration from 61 patients with SAP were collected with mean steady state trough concentration of vancomycin of (7.7±4.4) mg/L, which was significantly lower than standard concentration (15 mg/L,P < 0.001). Apparent volume of distribution (Vd) and clearance of vancomycin was (1.06±0.26) L/kg and (8.9±2.8) L/h. The serum steady state trough concentration of vancomycin in ARC group (n = 33) was significantly lower than that in non-ARC group (n = 28; mg/L: 6.7±3.5 vs. 8.2±4.1, P < 0.01), clearance was significantly increased (L/h: 9.8±2.9 vs. 7.7±2.2,P < 0.01). Compared with non-SIRS group (n = 31), the serum steady state trough concentration of vancomycin in SIRS group (n= 30) was significantly lowered (mg/L: 6.1±3.2 vs. 13.0±4.2,P < 0.01), and clearance was significantly increased (L/h: 9.4±2.0 vs. 7.1±2.1,P < 0.05). Compared with the only increasing vancomycin dose group (n = 29), vancomycin continuous infusion for 24 hours (n = 21) could significantly reduce daily dosage (mg/kg: 13.6±3.9 vs. 19.1±3.5,P < 0.01), increase the serum trough concentration (mg/L: 18.1±7.0 vs. 12.6±5.3,P < 0.01), and improve the AUCc-t/MIC.Conclusions The serum trough concentration of vancomycin was significantly reduced in SAP patients with ARC. The more serious of the SIRS is, the lower the vancomycin trough concentration is. Vancomycin 24-hour continuous infusion could optimize the PK/PD parameters, decrease the daily dose, increase the clinical effect, and reduce the bacterial resistance.

Objective To analyze the relationship between the least diameter of autogenous arteriovenous fistula and other parameters like flow rate and artery diameter. To identify an appropriate way in defining fistula stenosis. Methods Physical examination and Doppler ultrasound were used to examine the autogenous arteriovenous fistula of maintenance hemodialysis patients. Well?used wrist arteriovenous fistula was included. The least diameter of the fistula vein was found and marked by ultrasound, and the diameter and the distance between the point and the anastomotic stoma were measured. Diameters of different places along the cephalic vein of the fistula, including the forearm place, the place close to elbow and the upper arm place were measured by ultrasound. Meanwhile, diameter as well as flow velocity and flow rate of brachial artery, radial artery and ulnar artery were also measured. Result Sixty?eight patients were enrolled in the study. The average age of those patients was 52.56 ± 2.00 years old. Thirty?one patients were female. Forty?nine fistula were located on the left arm. The average diameter and flow rate of brachial artery were 5.72(5.34, 6.33) mm and 821.50 (540.50, 1075.00) ml/min, respectively. The average diameters of radial artery and ulnar artery were 3.95 ± 0.10mm and 3.17(2.73,3.75) mm, respectively. The least diameter of cephalic vein was 3.34 ± 0.11mm in average. The distance between the least place to the anastomotic stoma was 3.76±0.14cm in average. The diameter of forearm cephalic vein was averaged 5.36(4.52, 6.45) mm. Diameter of place close to elbow and the upper arm place in the cephalic vein were (5.57±0.12) mm and (5.80±0.14) mm, respectively. The least diameter of cephalic vein was positively and statistically associated with the diameter and flow rate of brachial artery as well as radial artery. The least diameter was also positively and statistically associated with the diameter of each place in the cephalic vein. Statistical inter?group difference was found when the division was based on the value of the least diameter. Conclusion sThe least diameter of the wrist autogenous arteriovenous fistula vein will indeed affect the whole diameter and flow rate of the fistula. The value of the least diameter is more closely associated with the fistula function rather than narrow rate.
