Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.

Objectives:the purpose of this study was to systematically evaluate the clinical value of cytokines in autoimmune diseases (AID). It was a kind of complex disease, and its pathogenesis involved cytokines, autoantibodies, immune cells and other immune factors. Especially some AID, such as Adult still′s disease (AOSD) and Takayasu arteritis(TA), had no specific biomarkers at present. This study was a retrospective case-control study.Methods:the data of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-8(IL-8) and interleukin-10(IL-10) in 834 AID patients from January 2019 to August 2022 were collected, and the serum levels of those cytokines in 30 healthy controls (HC) were detected at the same time. And AOSD, TA, systemic lupus erythematosus (SLE) and Behcet′s syndrome (BS) were divided into active group and inactive group. In addition, we also made a subgroup analysis of two important organs involved in SLE (kidney and nervous system). GraphPad Prism 9 and R 4.2.2 software were used. Nonparametric tests (Kruskal-Wallis H test, Mann-Whitney U test) were used to compare the differences among groups, and Dunn′s method was used to correct the false positive caused by multiple tests. Results:To compare the level of IL-6 in each group, except Behcet syndrome (BS) group and antiphospholipid syndrome (APS) group, the serum IL-6 level of AID group was higher than that of HC group, with antineutrophil cytoplasmic antibodies associated vasculitis(AAV) [3.85(2.00,8.55) pg/ml], idiopathic inflammatory myopathies(IIM) [7.80(2.50,6.50)pg/ml], IgG4-related disease(IgG4RD) [3.65(2.08,12.83) pg/ml], rheumatoid arthritis (RA) [5.50(2.20,16.10) pg/ml], SLE[4.70(2.75,16.55) pg/ml], Sj?gren syndrome(SS) [3.20(2.00,8.90) pg/ml], systemic sclerosis(SSc) [2.70(2.00,8.90) pg/ml], TA[3.40 (2.00,6.50) pg/ml], other AID diseases[4.40(2.00,11.10) pg/ml], especially AOSD [15.20(2.10, 39.20) pg/ml]. After correction, the differences were statistically significant ( P c<0.05). At the same time, the levels of serum TNF-α [7.40(5.60,10.95) pg/ml]and IL-10 [5.00(5.00, 7.58) pg/ml] in AOSD group were significantly higher than those in HC group[7.15(5.93,8.00) pg/ml,5.00(5.00,5.00) pg/ml] after correction ( P c<0.05). At the same time, the levels of serum TNF-α and IL-10 in AOSD group were higher than those in HC group. The serum levels of IL-6 and IL-8 in patients with active AOSD, BS, SLE and TA were significantly higher than those in patients without active disease (all P<0.05). In addition, the level of serum IL-8 in lupus nephritis group was significantly higher than that in non-lupus nephritis group ( P<0.05). At the same time, the serum levels of IL-6, IL-8 and TNF-α in neuropsychiatric lupus erythematosus group were significantly higher than those in non-neuropsychiatric lupus erythematosus group ( P<0.05), but there was no significant difference in IL-10 between neuropsychiatric lupus group and non-neuropsychiatric lupus erythematosus group. Conclusions:there was a close relationship between AID and cytokines. At present, the change of serum IL-6 level was the most classic one in clinical routine.

Objective To explore the influence of prozone effect on anti-nuclear antibodies (ANA) testing by indirect immunofluorescence assay (IIFA).Methods The samples with high titer of ANA (≥1∶1 000) were selected from 880fresh serum samples, and were subsequently diluted in 1∶100, 1∶1 000and 1∶10 000ratio.Prozone effect was defined as fluorescence intensity from 1∶1 000dilution was stronger than that from1∶100dilution.The samples with prozone effect were determined manually or by Sprinter XL and EUROPattern.The samples with prozone effect were further characterized by combinations of fluorescence patterns, fluorescence intensities and autoantibody specificities.Results A total of 880samples were tested.Importantly, 34samples displayed prozone effect (3.86％in total and 29.57％in samples with ANA≥1∶1 000).Interestingly, prozone effect was identified by manual detection as well as by Sprinter XL with similar fluorescence patterns and fluorescence intensities.Notably, EUROPattern can only select the central area for identification.Among all samples with prozone effect, 74.42％samples exhibited fluorescence intensities of≥1∶10 000.Speckled pattern was the most prevalent fluorescence patterns in samples with prozone effect (46.51％).In addition, anti-RNP antibodies (62.79％) were the most popular autoantibodies in samples with prozone effect, followed by anti-dsDNA antibodies (51.16％) and anti-SSA antibodies (51.16％).Conclusion Prozone effect was present in ANA testing, especially in samples with high titers, resulting in underestimating the titers.The study highlighted that special attention should be paid to the prozone effect in clinical practice.

Objective To study the predictive values of the general movements (GMs) assessment in writhing stage for motor development outcomes in infants with severe neonatal jaundice.Method From December of 2012 to December of 2017,infants with severe neonatal jaundice (serum bilirubin reaching the corresponding level of exchange transfusion according to the reference nomogram) in our hospital were enrolled in the study.Inclusion criteria included corrected gestational age of 37 to 48 weeks,serum bilirubin level below phototherapy intervention value after treatment and general and detailed assessment were carried out in writhing stage when the infant was stable.The patients were regularly followed-up until one-year-old to evaluate the predictive values.Result A total of 241 patients with severe neonatal jaundice were enrolled in the study,including 153 males (63.5％) and 88 females (36.5％),with gestational age between 35 and 42 weeks.The mean gestational age was (37.9± 1.8) weeks,the average birth weight was (3 057±480) g,and the mean serum bilirubin value was (458.9± 119.1) μmol/L.The general evaluation of the GMs was normal in 15 cases (6.2％),and abnormal in 226 cases (93.8％) with 217 cases (90.0％) were poor repertoire (PR) and 9 cases (3.7％) were cramped-synchronized (CS).The predictive values of abnormal GMs for abnormal motor development outcomes were as following:sensitivity 100％,specificity 7.6％,negative predictive value(NPV) 100％.The predictive values of CS for cerebral palsy were as following:sensitivity 22.2％,specificity 97.8％,NPV 94.0％.Detailed evaluation of 241 subjects showed that 13 items had statistically significant differences in the prediction of cerebral palsy (P＜0.05),and 18 items in the prediction of abnormal motor development (P＜0.05).Conclusion The CS pattern and detailed assessment of GMs in the writhing stage may be correlated with the outcomes of motor development in infants with severe neonatal jaundice until one-year-old.

Objective This study aimed to assess the diagnostic value of anti-mutated citrullinated vimentin (MCV) antibodies in rheumatoid arthritis (RA) and its correlation with disease progression, extra-articular manifestations and overlap syndrome. Methods Retrospective Studies. Clinical data of 837 patients in PekingUnionMedicalCollegeHospitalfrom June to August 2017 were collected, including the result of anti-MCV, anti-cyclic citrullinated peptide (anti-CCP) antibodies, rheumatoid factor (RF), erythrocyte sedimentation rate (ESR) and High-sensitivity-C-reactive protein (CRP). According to the 1987 American College of Rheumatology classification criteria for rheumatoid arthritis, there were 323 patients diagnosed with RA, including 59 males and 264 females with the average age of 51 years. According to whether the RA patients have overlap syndrome with other autoimmune disease (AID) or have extra-articular manifestations, 258 cases were categorized into RA group, including 47 males and 211 females with the average age of 50 years; 14 cases were categorized into the group of overlap syndrome, including 1 male and 13 females with the average age of 36 years;51 cases were categorized into the group of extra-articular manifestations, including 11 males and 40 females with the average age of 59 years.According to 2010 rheumatoid arthritis classification criteria for destruction in joints, the radiographic changes were divided into 4 stages. There were 203 casesenrolled in our study, 88 caseswere fitted into early stage group (stage I)including 21 males and 67 females with the average age of 48 years; 115 caseswere fitted into progressive stage group, which compromisedstageⅡ (interim stage), stage Ⅲ (severe stage) and stage Ⅳ(final stage) cases, including 19 males and 96 females with the average age of 53 years. Mann-Whitney U test, x2 test, Receiver operating characteristic (ROC) curves and Spearmancorrelation coefficientwere used in Statistical analysis. Results Ⅰ Amongdiagnosed RA patients, 199 (61.6％) cases were positive for anti-MCV, anti-CCP and RFsimultaneously, 42 (13％) cases were positive for anti-MCV, which was higher than anti-CCP positive (1 cases, 0.3％) or RF positive (7cases, 2.2％). The difference was statistically significant(P<0.001, P<0.001). ⅡROC was calculated and MCV=35.95 U/ml was used as best-fit cut-off value. The AUC for anti-MCV was 0.867, while the sensitivity was 80.5％and specificity was 80.9％.ⅢThe detection levels of anti-MCV (682.8 (106.4-1000.0)), anti-CCP (407 (4.0-1536.0)) and RF (82.8 (21.1-244.9)) in the group of progressive stage were higher than those in the group of early stage (114.5 (28.5-1000.0), 62.5 (5.0-1020.7), 50.1 (6.7-127.1)), which showed a significant difference(P<0.05, P<0.05, P<0.05). The anti-MCV, anti-CCP and RF were positively related to the degree of joint destruction (r=0.229, P<0.05;r=0.187, P<0.05;r=0.167, P<0.05);anti-MCV and anti-CCP were positively related to extra-articular manifestation (r=0.152, P<0.05;r=0.136, P<0.05). Conclusion Anti-MCV antibodies are more sensitive in patients with RA, and have complementary diagnostic value for anti-CCP and RF-negative patients; high levels of anti-MCV and anti-CCP in RA patients are associated with RA progression and extra-articular involvement.

Objective: To improve clinical management of maternal and neonatal listeriosis through analyzing the clinical characteristics and antibiotic treatment. Methods: A retrospective analysis of 26 cases of listeriosis, including their demographic and clinical features, was conducted, involving 16 pregnant women from Civil Aviation General Hospital, Xiamen Humanity Hospital, Tongzhou Maternal and Child Health Hospital of Beijing, Beijing Tiantan Hospital, Tangshan Maternal and Child Health Hospital, the Fourth Hospital of Tianshui City from October, 2011 to May, 2018, and 10 newborns from the Fourth Hospital of Tianshui City, Tangshan Maternal and Child Health Hospital, Zhengzhou Children's Hospital from February, 2016 to April 2018. Descriptive methods were used for data analysis. Results: (1) Among the 16 gravidas, one, five and 10 developed the infection in the 1st, 2nd and 3rd trimester of pregnancy, respectively, and eight had pregnancy complications. Furthermore, all of them developed fever [(38.9±0.5) ℃]. Symptoms such as cough, nasal congestion, runny nose, sore throat, dizziness, headache and other flu-like symptoms were observed in six cases. Gastrointestinal symptoms and flu-like symptoms were presented in four. Fetal distress, tachycardia and decreased fetal movement occurred in 11 cases. Elevated C-reactive protein and white blood cell count were detected in 16 and 14, respectively. Eight underwent placental pathological examination which shown various degrees of pathological changes, including neutrophil infiltration, acute chorioamnionitis and inflammatory necrosis. The main empirical antibiotic treatment for the 16 patients was cephalosporins and only four covered Listeria monocytogenes. Only two delivered at term, while the others (14/16) ended in miscarriage, premature delivery or stillbirth. (2) Among the 10 newborns with listeriosis, there were eight early-onset infections and two late-onset infections. All of them were febrile [(38.6±0.6)℃]. Six had cyanosis, groaning, foaming and three concave sign; five showed shortness of breath; meningitis and skin rash were found in one, respectively. All had elevated white blood cell and C-reactive protein. Six received antibiotics covering Listeria monocytogenes during the initial empirical treatment. Four were treated with cephalosporins alone, one of which died after the treatment was withdrawn. One was cured by initial treatment with meropenem alone, while eight recovered after adjustment of treatment with ampicillin, penicillin, meropenem, vancomycin alone, or meropenem combined with ampicillin or vancomycin. (3) The isolates that were susceptible to penicillin, ampicillin and meropenem accounted for 96.1% (25/26) all together and 88.5% (23/26) were susceptible to compound sulfamethoxazole. Conclusions There is no specific clinical manifestations of maternal or neonatal listeriosis. Maternal listeriosis is often characterized by acute onset and high incidence of adverse pregnancy outcomes.

OBJECTIVE: To investigate the effects of Niaoduqing granule on the urine metabolic profile in chronic renal failure (CRF) rats. METHODS: Thirty six male SD rats were divided into the normal control group, the model group, and the Niaoduqing group with 12 rats in each group. The CRF was induced by gavage of 250 mg·kg·d adenine for 21 d. UPLC-Q-TOF-MS/MS technique was used in combination with principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) to analyze the urine metabolic profiles in three groups. The endogenous substances with the variable importance projection (VIP)>1 and <0.05 were screened as the potential biomarkers for CRF, and enrichment analysis of metabolic pathways was carried out. RESULTS: Compared with the normal control group, the model group had lower body weight, higher kidney coefficient, higher serum creatinine and urea nitrogen levels (all <0.01), while the above indexes in the Niaoduqing group were ameliorated compared with the model group (all <0.01). Fifteen potential biomarkers were found in the urine of the model group, which were involved in 9 metabolic pathways including phenylalanine, tyrosine and tryptophan biosynthesis, glyoxylate and dicarboxylate metabolism, valine, leucine and isoleucine biosynthesis, arachidonic acid metabolism, cysteine and methionine metabolism, tricarboxylic acid cycle, glycerophosphatide metabolism, tryptophan metabolism and tyrosine metabolism. CONCLUSIONS Niaoduqing granules has therapeutic effect on rats with CRF, which may be related to the regulation of amino acid metabolism, lipid metabolism and energy metabolism.
