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 investigate the prevalence and associated factors of diabetic retinopathy (DR) among diabetic residents in Longyan of Fujian Province.Methods:A investigative research. From January 2022 to December 2023, a total of 10 061 diabetic patients enrolled in the chronic disease follow-up management system from 112 towns and sub-districts in 7 counties and districts of Longyan of Fujian Province were selected as the target population. A questionnaire survey, routine physical examination, vision test, and non-mydriatic fundus photography were conducted. A total of 762 cases with missing height, weight, blood pressure, fasting plasma glucose (FPG), and diabetes duration, and 507 cases with unclear fundus photography were excluded, resulting in 8 792 cases included in the final statistical analysis. DR diagnosis and classification were based on the 2019 International Clinical Classification of DR. The prevalence of DR was calculated for single-eye or double-eye DR cases as 1 case; the more severe eye was used for DR grading in double-eye DR cases. Statistical analysis was performed by grouping based on the presence or absence of DR and dividing into age groups ≤67 years and >67 years. χ2 test was used to analyze factors associated with prevalence; binary multivariate logistic regression analysis was employed to identify influencing factors of DR. Results:Among the 8 792 cases, 888 (10.1%, 888/8 792) were diagnosed with DR (DR group), and 7 904 (89.9%, 7 904/8 792) had no DR (non-DR group). Compared to the non-DR group, the DR group showed significant increases in FPG ( Z=-12.448), diabetes duration ( Z=-18.936), systolic blood pressure ( Z=-4.237), diastolic blood pressure ( Z=-2.881), and body mass index (BMI) ≥24 kg/m 2 ( P<0.001). Significant differences were also found between the two groups in hypertension ( χ2=11.450), hyperlipidemia ( χ2=5.100), kidney disease ( χ2=7.039), family history of diabetes ( χ2=5.025), and regular medication use ( χ2=66.034) ( P<0.05). There were 4 688 cases in the ≤67 years group and 4 104 in the >67 years group. In the ≤67 years group, significant differences in DR prevalence were found for FPG levels ( χ2=111.754), diabetes duration ( χ2=231.658), BMI ( χ2=12.404), systolic blood pressure ( χ2=17.912), regular medication use ( χ2=40.727), hyperlipidemia ( χ2=6.816), and hypertension history ( χ2=6.775) ( P<0.05). In the >67 years group, significant differences in DR prevalence were found for FPG levels ( χ2=59.916), diabetes duration ( χ2=128.362), systolic blood pressure ( χ2=5.183), regular medication use ( χ2=22.097), kidney disease ( χ2=6.251), and family history of diabetes duration ( χ2=4.967) ( P<0.05). No significant differences in DR prevalence were found based on sex, education level, smoking history, alcohol consumption, exercise habits, heart disease history, or other family disease history ( P>0.05). Logistics regression analysis results show that patients aged >67 years, FPG [odds ratio (OR)=1.074, 95%confidence interval ( CI) 1.046-1.102], diabetes duration ( OR=1.088, 95% CI 1.071-1.106), systolic blood pressure ( OR=1.007, 95% CI 1.001-1.013), and kidney disease ( OR=3.617, 95% CI 1.268-10.320) were identified as risk factors for DR ( P<0.05). In patients aged ≤67 years, FPG ( OR=1.088, 95% CI 1.067-1.110), diabetes duration ( OR=1.108, 95% CI 1.091-1.125), and systolic blood pressure ( OR=1.008, 95% CI 1.003-1.013) were identified as independent risk factors for DR ( P<0.05), while BMI ≥24 kg/m 2 ( OR=0.934, 95% CI 0.908-0.965) was a protective factor for DR ( P<0.05). Age, regular medication use, hypertension, and hyperlipidemia were identified as potential confounding factors for DR occurrence. Conclusions:The prevalence of DR among diabetes patients in Longyan of Fujian Province, is 10.1%. FPG, diabete duration, and systolic blood pressure are independent risk factors for DR, while age, regular medication use, hypertension, and hyperlipidemia are potential confounding factors for DR occurrence.

Objective To investigate the-75 G/A single-nucleotide polymorphism in the promoter region of apolipoprotein A1 gene(apoA1)and its association with gestational diabetes mellitus(GDM)in pregnant women and to provide references for the exploration in the molecular genetic basis of GDM.Methods A total of 626 GDM patients and 1022 normal pregnant women,ie,the controls,were included in the study.The genotyping of apoA1-75 G/A polymorphism was performed by polymerase chain reaction and restriction fragment length polymorphism(PCR-RFLP)analysis.Total cholesterol(TC),triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),and glucose(Glu)were measured by enzymatic methods.Plasma insulin(INS)was measured by chemiluminescence immunoassay.The protein levels of apoA1 and apoB were measured by the turbidimetric immunoassay.Results Allele frequencies of G and A were 0.718 and 0.282 in the GDM group and 0.713 and 0.287 in the control group,respectively.Distribution of the genotype frequencies was found to be in Hardy-Weinberg equilibrium in both the GDM and control groups.There was no significant difference in the frequencies of alleles G and A and the genotypes of apoA1-75 G/A polymorphism between the GDM and the control group(P>0.05).In the GDM group,the carriers with the genotype AA were associated with significantly higher levels of TC,HDL-C,and apoA1 than those with genotypes GG and GA did(all P<0.05).After the GDM patients were divided into obese and non-obese subgroups,the genotype-related apoA1 variation was observed only in obese patients,while the genotype-related TC and HDL-C variations were evident in non-obese patients(P<0.05).In the control group,carriers of genotypes AA and GA had higher systolic blood pressure(SBP)and HDL-C than the carriers of genotype GG did(all P<0.05).Carriers of genotypes AA had significantly lower Glu levels than carriers of genotypes GG and GA did(P<0.05).The control subjects were further divided into subgroups according to their body mass index(BMI).Analysis of the subgroups showed that AA carriers were associated with higher SBP levels in the obese control women only,while lower Glu levels were evident in both obese and non-obese control women.Conclusion These results suggest that-75 G/A polymorphism in the apoA1 gene is not associated with GDM.However,the genetic variation is closed associated with the plasma apoA1,HDL-C,and TC levels in GDM patients and plasma HDL-C,Glu,and SBP levels in the control subjects.The apoA1 variant-associated lipids and SBP variation is BMI dependent in both groups.

ObjectiveTo explore the mechanism of Buyang Huanwutang combined with bone marrow mesenchymal stem cell (BMSC) transplantation in the treatment of spinal cord injury (SCI). MethodDifferent concentrations (12.5, 25, 50 g·kg-1) of Buyang Huanwutang were administrated to rats by gavage. The spinal cord function of rats was measured by modified Tarlov score, and the most suitable concentration of Buyang Huanwutang was screened out. SD rats were then divided into 6 groups, namely, the sham operation group (gavage of equal amount of normal saline), the model group (gavage of equal amount of normal saline), the Buyang Huanwutang group (gavage of 25 g·kg-1 Buyang Huanwutang), the BMSC transplantation group (tail vein injection of BMSCs 1 mL), the Buyang Huanwutang+BMSC group (gavage of 25 g·kg-1 Buyang Huanwutang and tail vein injection of BMSCs 1 mL), the Buyang Huanwutang+BMSC+LY294002 group (gavage of 25 g·kg-1 Buyang Huanwutang and tail vein injection of BMSCs 1 mL and 40 mg·kg-1 LY294002), with 10 rats in each group. The spinal cord function was measured by the modified Tarlov score, inclined plate test, and latency of cortical somatosensory evoked potential. Immunohistochemistry was used to detect the number of 5-bromo-2-deoxyuracil nucleoside (Brdu)-labeled positive cells in the spinal cord tissue. The protein expression levels of phosphorylated protein kinase B (p-Akt), glycoprotein 130 (gp130), and interleukin-6 (IL-6) in spinal cord were detected by Western blot. ResultAs compared with the sham operation group, the Tarlov score and the critical angle of tilt plane in the model group were significantly decreased (P<0.05), and the latency of cortical somatosensory evoked potential wave and the protein expression levels of p-Akt, gp130, and IL-6 were significantly increased (P<0.05). As compared with the model group, the Tarlov score and the critical angle of tilt plane in the sham operation group and each treatment group were significantly increased (P<0.05), and the latency of cortical somatosensory evoked potential wave and the protein expression levels of p-Akt, gp130, and IL-6 were significantly decreased (P<0.05). As compared with the BMSC group, the Tarlov score and the critical angle of inclined plane in the Buyang Huanwutang+BMSC group increased (P<0.05), the latency of cortical somatosensory evoked potential wave and the protein expression levels of p-Akt, gp130, and IL-6 decreased (P<0.05), and the number of Brdu-labeled positive cells increased 5 weeks after transplantation (P<0.05). As compared with the Buyang Huanwutang+BMSC group, the Tarlov score and the critical angle of the inclined plane in the Buyang Huanwutang+BMSC+LY294002 group increased (P<0.05), and the latency of cortical somatosensory evoked potential wave and the protein expression levels of p-Akt, gp130, and IL-6 decreased significantly (P<0.05). Five weeks after transplantation, the number of Brdu-labeled positive cells increased significantly in the Buyang Huanwutang+BMSC+LY294002 group (P<0.05). ConclusionBuyang Huanwutang can promote BMSCs migration and restore spinal cord function by inhibiting phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signal.

OBJECTIVE:
To analyze recurrence and progression patterns of primary central nervous system lymphoma (PCNSL) in patients without whole brain radiotherapy (WBRT) and assess the value of WBRT in PCNSL treatment.
METHODS:
This retrospective single-center study included 27 patients with PCNSL, who experienced recurrence/progression after achieving complete remission (CR), partial remission, or stable disease following initial treatments with chemotherapy but without WBRT. The patients were followed up regularly after the treatment for treatment efficacy assessment. By comparing the anatomical location of the lesions on magnetic resonance images (MRI) at the initial diagnosis and at recurrence/progression, we analyzed the patterns of relapse/progression in patients with different treatment responses and different initial status of the lesions.
RESULTS:
MRI data showed that in 16 (59.26%) of the 27 patients, recurrence/progression occurred in out-field area (outside the simulated clinical target volume [CTV]) but within the simulated WBRT target area in 16 (59.26%) patients, and within the CTV (in-field) in 11 (40.74%) patients. None of the patients had extracranial recurrence of the tumor. Of the 11 patients who achieved CR after the initial treatments, 9 (81.82%) had PCNSL recurrences in the out-field area but within WBRT target area; of the 13 patients with a single lesion at the initial treatment, 11 (84.62%) experienced PCNSL recurrence in the out-field area but within WBRT target area.
CONCLUSIONS
Systemic therapy combined with WBRT still remains the standard treatment for PCNSL patients, especially those who achieve CR after treatment or have a single initial lesion. Future prospective studies with larger sample sizes are needed to further explore the role of low-dose WBRT in PCNSL treatment.

OBJECTIVE:
Immunotherapy has brought significant clinical benefits to a subset of patients, but has thus far been disappointing in the treatment of immunologically "cold" tumors. Existing biomarkers that can precisely identify these populations are insufficient. In this context, a potential cold tumor microenvironment (TME) marker FARSB was investigated to reveal its impact on TME and patients' response to immunotherapy across pan-cancer.
METHODS:
The expression levels and mutational landscape of FARSB in pan-cancer were investigated. Kaplan-Meier and univariate Cox regression analyses were applied to analyze the prognostic significance of FARSB. Pathways affected by FARSB were investigated by gene set enrichment and variation analysis. The relationship between FARSB expression and immune infiltration was examined using the TIMER2 and R packages. Single-cell RNA sequencing (scRNA-seq) data of several cancer types from GSE72056, GSE131907, GSE132465, GSE125449 and PMID32561858 were analyzed to validate the impact of FARSB on the TME. The predictive effect of FARSB on immunotherapy efficacy was explored in 3 immune checkpoint inhibitors (ICIs)- treated cohorts (PMID32472114, GSE176307, and Riaz2017).
RESULTS:
FARSB expression was significantly higher in 25 tumor tissues than in normal tissues and was associated with poor prognosis in almost all tumor types. FARSB expression exhibited a strong association with several DNA damage repair pathways and was significantly associated with TP53 mutation in lung adenocarcinoma (P < 0.0001, OR=2.25). FARSB characterized a typical immune desert TME and correlated with impaired expression of chemokines and chemokines receptors. Large-scale scRNA-seq analysis confirmed the immunosuppressive role of FARSB and revealed that FARSB potentially shapes the cold TME by impeding intercellular interactions. In 3 ICI-treated cohorts, FARSB demonstrated predictive value for immunotherapy.
CONCLUSION
This study provides a pan-cancer landscape of the FARSB gene by integrated single-cell and bulk DNA sequencing analysis and elucidates its biological function to promote DNA damage repair and construct the immune desert TME, suggesting the potential value of FARSB as a novel marker for stratifying patients with poor immunotherapeutic benefits and "cold" TME.

OBJECTIVE:
To present on a prenatally diagnosed case with complex structural rearrangements of chromosome 8.
METHODS:
Chromosome karyotyping, chromosomal microarray analysis (CMA) and fluorescence in situ hybridization (FISH) were carried out for a fetus with increased nuchal thickness.
RESULTS:
The karyotype of the amniotic fluid sample showed extra materials on 8p. FISH revealed a centromeric signal at the terminal of 8p with absence of telomeric signal. CMA revealed partial deletion of 8p23.3 [(208049_2256732)×1], partial duplication of 8p23.3p23.2 [(2259519_3016818)×3], and partial duplication of 8q [8q11.1q12.2(45951900_60989083)×3].
CONCLUSION
The complex structural rearrangements of chromosome 8 in this case has differed from the commonly seen inv dup del(8p).
