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.

Objective To systematically evaluate and sequentially analyze the clinical efficacy and safety of Baogong Zhixue Granules for the treatment of abnormal uterine bleeding due to ovulation disorder.Methods The randomized controlled trials(RCTs)of Baogong Zhixue Granules for the treatment of abnormal uterine bleeding due to ovulation disorder were retrieved from the databases of CNKI,Wanfang Data,VIP,China Biology Medicine,PubMed,Embase,and Cochrane Library from the establishment of the databases to January 5th,2023.Literature screening and data extraction were conducted according to Cochrane Handbook for Systematic Reviews of Interventions,and Meta-analysis was performed by RevMan 5.4.Results Totally 15 articles were included,involving 1 425 patients.Meta-analysis results showed that Baogong Zhixue Granules could effectively improve the clinical efficacy of abnormal uterine bleeding due to ovulatory disorder(RR=1.17,95%CI[1.13,1.23],P<0.000 01),shorten hemostasis time[bleeding control time(MD=-6.35,95%CI[-8.89,-3.81],P<0.000 01),complete hemostasis time(MD=-12.56,95%CI[-16.22,-8.89],P<0.000 01)],reduce endometrial thickness(MD=-1.26,95%CI[-1.71,-0.80],P<0.000 01),reduce hemoglobin loss(MD=13.35,95%CI[11.41,15.29],P<0.000 01),improve the score of uterine bleeding(MD=-2.22,95%CI[-2.43,-2.01],P<0.000 01),and reduce the recurrence of disease(RR=0.37,95%CI[0.19,0.72],P=0.004).There was no statistical significance between the test group and the control group in terms of adverse reactions(P=0.82).The trial sequential analysis of the total efficiency was carried out,and the cumulative included research passed the traditional threshold and trail sequential analysis threshold.Conclusion Baogong Zhixue Granules have a certain clinical efficacy in the treatment of abnormal uterine bleeding due to ovulation disorder,but there may be publication bias in the study,and higher quality clinical RCTs need to be carried out.

Objective To explore the association of urinary level of kidney injury molecule-1 (KIM-1) with renal tubulointerstitial lesions in patients with lupus nephritis (LN). And to find a potential clinical biomarker, which could reflect the specific tubulointerstitial lesions of LN. Methods Sixty cases of biopsy proven new-onset LN patients were enrolled into the study. And 10 normal kidney tissues were collected, which came from 10 patients with kidney trauma or renal tumor nephrectomy. Sixty patients with LN were divided into mild disease group, moderate disease group, severe disease group and the extremely severe disease group according to the criteria of 2000 Hill's morphologic index for the evaluation of renal pathology. Urine and renal tissues specimen were collected. The clinical and pathological data were analyzed retrospectively. Urine level of KIM-1 was detected by enzyme linked immunosorbent assay (-). Immunohistochemical staining was used to observe the expression of KIM-1 in the renal tissue. T-test, One-Way analysis of variance(ANOVA) test or rank sum test and Pearson or Spearman correlation analysis were used for statistical analysis. Results ①With the aggravation of tubulointerstitial lesions, the urinary level of KIM-1 was increased gradually, which was shown in the control group [(0.32 ±0.03) ng/ml], mild group [(2.31 ±0.30) ng/ml], moderate group [(6.12 ±0.51) ng/ml], severe group [(12.51 ±1.83) ng/ml] and the extremely severe group [(15.30 ±2.11) ng/ml] (all P<0.05); ② With the aggravation of tubulointerstitial lesions, the expression of KIM-1 in the renal tissue was increased gradually which was shown in the control group [(2.13±0.12)%], mild group [(35.01±0.33)%], moderate group [(51.12± 2.11)%], severe group [(63.50 ±1.80)%] and the extremely severe group [(75.31 ±3.22)%] (all P<0.05);③ Urinary KIM-1 level in LN patients was positively correlated with the expression of KIM-1 in the renal tissue (r=0.870, P<0.01);④Urinary KIM-1 level in LN patients was positively correlated with 24 hUP, systemic lupus erythematosus disease activity index (SLEDAI), renol (R)-SLEDAI, glomerular activity index (GAI), tubulointerstitial ativity imdex (TLAI), chronicity (AI) (r=0.826, 0.741, 0.824, 0.743, 0.871, 0.741, P<0.05), and was negatively correlated with estimated glomerular filtration rate (eGFR) (r=-0.726, P<0.05), while was not correlated with CI (r=0.532, P>0.05). The expression of KIM-1 in the renal tissue was positively correlated with serum creatinine (SCr), quantity of 24 h UP, SLEDAI, R-SLEDAI, GAI, TLAI and AI (r=0.780, 0.780, 0.812, 0.727, 0.735, 0.910, 0.701, P<0.05), and was negatively correlated with eGFR (r=-0.727, P<0.05), while it was no correlated with CI (r=0.543, P>0.05). Conclusion Urinary KIM-1 enables to assess the tubulointerstitial lesion in LN patients, and it can be a sensitive biomarker to predict the tubulointerstitial damage and to evaluate the degree of tubulointerstitial lesions.
