Effects of modified triangular flap for third molar extraction on distal periodontal health of second molar: A randomized controlled study.

Objective: The aim of this study was to assess the effect of flap design for impacted mandibular third molar extraction on the distal periodontal tissue of their neighbors clinically, immunologically, and microbiologically.

Study Design: This randomized controlled study comprised 100 patients who were allocated randomly to receive either a triangular flap or a modified triangular flap. The distal periodontal pocket depth, plaque index, bleeding on probing, the presence of Actinobacillus and and the level of interleukin-1β, interleukin-8 and matrix metalloproteinase-8 of adjacent second molars were measured at baseline, and 1, 4 and 8 weeks after surgery.

Diagnostic Value of Color Doppler Ultrasound and Contrast-Enhanced Ultrasound in the Artery Steal Syndrome After Orthotopic Liver Transplantation.

Purpose: This study aimed to investigate the application of color Doppler ultrasound (CDU) and contrast-enhanced ultrasound (CEU) in the early diagnosis of arterial steal syndrome (ASS) after orthotopic liver transplantation (OLT).

Patients And Methods: A total of 1827 patients received OLT in our department between January 2007 and December 2021, and CDU and CEU were performed after surgery. Ultrasonographic data were collected and further analyzed.

Dysbiosis of saliva microbiome in patients with oral lichen planus.

Background: Oral microbiota is not only important for maintaining oral health but also plays a role in various oral diseases. However, studies regarding microbiome changes in oral lichen planus (OLP) are very limited. To the best of our knowledge, there has been only two studies investigating salivary microbiome changes in OLP.

[Influence of periodontal non-surgical therapy on serum interleukin 6 expression and carotid artery wall in rats with periodontitis and type 2 diabetes mellitus].

Objective: To study the effect of periodontal non-surgical treatment on serum interleukin-6 (IL-6) expression and carotid vascular wall in a rat model of chronic periodontitis (CP) with type 2 diabetes mellitus (T2DM).

Methods: Twenty-eight 6-week-old SD rats were randomly divided into group A (control group, 7 rats) and group B (T2DM+CP group, 21 rats). According to different intervention measures, group B was randomly subdivided into B1 (natural process), B2 (periodontal mechanical treatment), and B3 (periodontal mechanical treatment + 2% minocycline hydrochloride + systemic metronidazole plus amoxicillin).

Effects of Periodontal Intervention on Levels of Serum High-sensitivity C-reactive Protein and Interleukin 6, and on Carotid Artery in Rats with Chronic Periodontitis and Hyperlipidemia.

Objective: To investigate the effects of nonsurgical periodontal therapy on the serum interleukin 6 (IL-6) and high-sensitivity C-reactive protein (hsCRP) and on the carotid artery in rats with chronic periodontitis (CP) and with or without hyperlipidemia (HL).

Methods: A total of 29 Sprague-Dawley rats were randomly divided into two groups: group A (CP, n = 14) and B (CP + HL, n = 15), and subjected to the corresponding treatment. Groups A and B were further divided into groups A1/B1 (without periodontal interventions) and A2/B2 (with periodontal interventions).

[Nonlinear Regression Methods of Ethanol Raman Spectra Quantitative Analysis].

Ethanol concentration quantitative analysis of ethanol-water solution can be realized by measuring the ratio of Raman characteristic peak heights. The content of ethanol can be determined by linear relation between relative intensity ratio and ethanol concentration. However, this analytical method only applies to the ethanol solution at low concentration.

[A preliminary study on the genetic mode of aggressive periodontitis in Chinese Han nationality].

Objective: To investigate the potential genetic mode of aggressive periodontitis (AgP) in Chinese Han nationality.

Methods: A total of 233 subjects from 73 nuclear families were recruited. All probands were diagnosed according to the criteria of AgP in 1999 classification of periodontal diseases.

[Monitoring vascular complications following liver transplantation using color Doppler flow imaging].

Objective: To assess the value of color Doppler flow imaging (CDFI) in monitoring vascular complications following orthotopic liver transplantation (OLT).

Methods: Seven hundred ninety-two patients who received OLT from April 2002 to December 2006 in the Organ Transplantation Center, General Hospital of Chinese People's Armed Police Forces, Beijing, and underwent CDFI examinations in different periods after OLT were enrolled in this study. Their vascular complications were monitored by CDFI and confirmed by angiography or spiral CT.

[Interleukin-1 family polymorphisms in aggressive periodontitis patients and their relatives].

Objective: To study whether interleukin-1( IL-1 )genotype and/or alleles were associated with aggressive periodontitis (AgP) patients and their relatives.

Methods: Sixty-six AgP nuclear families including 66 probands and their 114 relatives were recruited. All probands were diagnosed as AgP according to 1999 classification of periodontal diseases and conditions, the diagnoses of their relatives were using a system of assessment (including the current and retrospective diagnosis and reported case history).

[Monitoring portal vein complications following liver transplantation by color Doppler flow imaging].

Objectives: To explore the diagnostic value of color Doppler flow imaging (CDFI) in monitoring portal vein complications (PVC) following orthotopic liver transplantation (OLT).

Methods: Five hundred and four patients received OLT and had CDFI examinations before and after their transplantations. CDFI monitoring parameters before the operation included portal vein diameter, blood flow velocity and the presence of thrombi within the portal vein.

Optimal annular computer-generated holograms for the generation of optical vortices.

We analyze a method for efficiently generating optical vortices by use of annular computer-generated holograms and a spatial light modulator. We found that there exists an optimal annular width by which the reconstructed vortex ring in the focal plane has the steepest gradient and the worthless subbright rings can be largely suppressed. We fitted a general formula for determining the value of this optimal annular width and propose a method for designing a multiring structure of optical vortices and specialized interferometric vortex patterns.

Purpose: The goal of this study was to explore the relationship between feeding methods and deciduous caries.

Methods: An investigation on children's feeding methods, caries prevalence and dmft was made, using 260 cases which were provided with whole primary teeth. Chi-square test was used for statistical analysis on feeding methods and caries prevalence, and variance analysis was used on feeding methods and dmft.

Optical vortex phase-shifting digital holography.

We report a new optical vortex phase-shifting method for digital holography, in which an optical vortex mode is taken as the reference beam for holographic recording, and the required phase shifts are directly generated by rotating the vortex mode. In digital reconstruction, the complex amplitude of the object wave can be retrieved by use of the conventional phase shifting algorithm on condition that the digital illumination beam is replaced by an vortex beam with the same topological charge as the reference used. Both the theoretical analysis and experimental results demonstrate the feasibility of this approach.
