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 value of enhanced magnetic resonance imaging(MRI)radiomics based on gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid(Gd-EOB-DTPA)in predicting the histopathological grading of hepatocellular carcinoma(HCC)before surgery.Methods A total of 101 patients with HCC who were treated in the Second Affiliated Hospital of Kunming Medical University from January 2021 to June 2024 were selected as study subjects and randomly assigned to the training set(n=70)and the test set(n=31)in a ratio of 7∶3.Radiomics features were extracted from portal venous phase(PVP)and hepatobiliary phase(HBP)images,and support vector machine(SVM)image omics model was constructed after dimensionality reduction by least absolute shrinkage and selection operator logistic regression.Model performance was assessed by area under the curve(AUC),accuracy,sensitivity,and specificity.Results After feature screening,the SVM model was constructed by retaining the best image omics features of 2 HBP,5 PVP and 11 combined models.The AUC of PVP,HBP and PVP+HBP combined models were 0.870,0.914 and 0.952,respectively,showing a good ability to distinguish between high and low grade HCC.Conclusion Compared with the independent model,PVP+HBP combined model has better performance in predicting HCC histopathological grading,and can be used as a non-invasive auxiliary tool to help distinguish between high-grade and low-grade HCC before surgery.

Objective:To explore the diagnostic value of digital mammography combined with serum glutathione specific gamma-glutamyl transpeptidase 1(CHAC1)and retinoic acid-induced protein 14(RAI14)in identifying benign and malignant breast masses.Methods:A total of 189 patients with breast masses who were treated at Handan Maternal and Child Health Care Hospital from June 2019 to June 2024 were prospectively selected as the research subjects.According to the results of pathological biopsy,they were divided into benign mass group(128 cases)and malignant mass group(61 cases).All patients underwent digital mammography detection.The levels of serum CHAC1 and RAI14 were detected by enzyme-linked immunosorbent assay(ELISA).The general clinical data of the patients were collected and analyzed.Multivariate logistic regression analysis was used to analyze the factors of influencing benign and malignant nature of breast masses.The receiver operating characteristic(ROC)curve was drawn to analyze the diagnostic value of CHAC1 and RAI14 for the benign and malignant nature of breast masses.The Kappa test was used to assess the consistency of results between each diagnostic method and the pathological detection.Results:For 189 patients with breast masses,digital mammography identified 56 cases of malignant masses and 133 cases of benign masses,and 13 cases of them were misdiagnosis and 18 cases of them were missed diagnosis.It showed a moderate consistency with the results of pathological detection(Kappa=0.617,P<0.05).Compared with the benign mass group,the levels of serum CHAC1 and RAI14 in the malignant mass group were significantly higher,and the differences of them between the two groups were statistically significant(t=12.249,12.512,P<0.05).The age,menopausal time,CHAC1 and RAI14 of the patients were all risk factors that can affect the benign and malignant nature of breast masses(OR=1.368,1.305,1.897,1.995,P<0.05).The area under curve(AUC),sensitivity and specificity of CHAC1 were respectively 0.816(95%CI:0.753～0.868),70.49%and 89.06%in diagnosing the benign and malignant nature of breast masses.These indicators of RAI14 were respectively 0.838(95%CI:0.778～0.888),68.85%and 89.84%in diagnosing the benign and malignant nature.The combined detection of the three methods identified 74 cases of malignant masses and 115 cases of benign masses,with 15 cases of misdiagnosis and 2 cases of missed diagnosis,which showed an extremely high consistency with the results of pathological detection(Kappa=0.805,P<0.001).The sensitivity(96.72%),negative predictive value(98.26%)and accuracy(91.01%)of the combined detection of digital mammography,serum CHAC1 and RAI14 were significantly higher than those of each alone detection of them,and the differences of them were significant(x2=15.310,16.623,15.310,11.690,12.402,11.572,5.276,5.276,4.677,P<0.05).Conclusion:The levels of serum CHAC1 and RAI14 appear increase in malignant breast masses,and digital mammography combined with serum CHAC1 and RAI14 has a certain of identification value for benign and malignant nature of breast masses.

OBJECTIVE To enhance the training quality of anticoagulation specialty clinical pharmacists,address the resource limitations of a single training base,and promote homogenization of training quality.METHODS A multi-base joint training system for anticoagulation specialty clinical pharmacists in the Beijing area was established.A mixed research method was employed,collecting data through performance comparisons,questionnaires,and qualitative interviews to compare the differences between the joint training model(experimental group,n=16)and traditional teaching model(the control group,n=17).RESULTS The established joint training system encompassed a unified joint training teaching plan,the formation of a joint training teaching team,the establishment of joint theoretical teaching courses,the implementation of joint case discussions and literature presentations,as well as strengthening the assessment throughout the joint training process.Compared to the control group[theoretical assessment of(76.44±3.66)points,case assessment of(84.31±3.27)points],the experimental group students achieved higher scores in theoretical assessment[(79.85±4.64)points]and case assessment[(88.70±5.51)points](P＜0.05).Through questionnaires and qualitative interviews,the trainees in experimental group were highly satisfied with the joint training model in terms of theoretical learning,communication skills,and teaching interaction.CONCLUSIONS The multi-base collaborative training system for anticoagulation specialty clinical pharmacists can integrate advantageous resources and significantly enhance the training effectiveness of anticoagulation specialty clinical pharmacists,offering value for wider promotion.

Objective:To evaluate the clinical effect of the position pillows for neuraxial anesthesia.Methods:This was a prospective randomized controlled trial. Four hundred and twelve patients regardless of gender, aged ≥18 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ, who underwent elective surgery under neuraxial anesthesia at Peking University Third Hospital from February to October 2023, were selected and divided into 2 groups ( n=206 each) using a random number table method: pillow group (P group) and control group (C group). Group C underwent the conventional procedure for neuraxial anesthesia. The patients were placed in a position using the position pillow on the basis of oral education before routine anesthesia in group P. The success rate of puncture at first attempt, puncture time and position placement time were recorded. The adjustment of position, body movement and occurrence of discomfort during the puncture were also recorded. The visual analogue scale score was used to evaluate the level of anxiety before positioning, after positioning and after anesthesia. The visual analogue scale score was used to evaluate the patient′s comfort and the operator′s satisfaction with position after the anesthesia was completed. Results:Compared with group C, the time for positioning was significantly shortened, the anxiety level was decreased after positioning and after anesthesia, the rate of improvement in anxiety was increased, the scores for the patient′s comfort and the operator′s satisfaction with position were increased ( P<0.05), and no significant changes were found in the success rate of puncture at first attempt, puncture time and incidence of body movement during the puncture and incidence of the adjustment of position ( P>0.05). No discomfort was observed in either group during the puncture. Conclusions:This new type of position pillows for the neuraxial anesthesia can not only optimize the effect of position placement, but also improve the patients′ comfort.

Objective:To discuss the aeromedical support enhancement measures by analyzing the disease spectrum and the aeromedical characteristics of temporarily grounded flying personnel.Methods:A retrospective analysis was conducted on the clinical data of 244 flying personnel who received medical treatment at the Southern Theater Air Force Hospital from November 2011 to March 2023 and were temporarily grounded in aeromedical assessment. The flying personnel were grouped by aircraft types (fighter, trans-bomber, helicopter) and flying hours (<2 000 h and ≥2 000 h), and the spectrum of temporarily unqualified flight diseases were statistically analyzed. The disease distributions of flying personnel in different aircraft types and flying hours were compared.Results:Among the 244 flying personnel (389 person-time) who were identified as temporarily grounded by aeromedical assessment, the major specialties involved were surgery (52.5%), internal medicine (24.6%) and neuropsychiatry (14.3%). The top 10 diseases leading to temporarily grounded were cervical and lumbar spine diseases, anxiety-depression, knee joint injury (surgical treatment), anal fistula (surgical treatment), sleep disorders, joint and soft tissue injuries, hypertension, ureteral stones, achilles tendon rupture and fracture (conservative treatment). There was a significant difference in the proportion of flying personnel temporarily grounded due to anxiety-depression among different aircraft types ( P=0.014). There were no significant differences in other diseases among flying personnel in different aircraft types (all P>0.05). The proportion of temporarily grounded flying personnel due to knee joint injury in flying hours <2 000 h was higher than that in flying hours ≥2 000 h, and the difference was significant ( χ2=4.47, P=0.035). Among the 71 flying personnel who underwent repeated ground observation, 28 were identified as qualified, 22 were grounded and 21 were still temporarily grounded. Conclusions:The proportion of flying personnel temporarily grounded due to diseases is relatively high. Accurate diagnosis and treatment of diseases and aeromedical assessment are important links to promote the early return of flying personnel.

Objective:To analyze the clinical characteristics of HBeAg-negative chronic hepatitis B virus (HBV) infection in indeterminate phase with a low viral load.Methods:One hundred and thirty-nine cases with persistent normal alanine aminotransferase (ALT) and HBeAg-negative chronic HBV infection with low viral load who visited the Department of Infectious Diseases of the Affiliated Hospital of Yan'an University from September 2013 to July 2021 were retrospectively collected. Patients were divided into low hepatitis B surface antigen (HBsAg) group ( n=59) and high HBsAg group ( n=80) according to the baseline hepatitis B surface antigen (HBsAg) level. The changes of various indicators at baseline and follow-up endpoints were analyzed between the two groups. The rate of HBsAg decrease ≥0.5 log 10IU/ml, HBV DNA negative conversion rate, ALT persistently normal rate, and liver stiffness measurement (LSM) persistently normal rate at the end of the follow-up were compared. The t-test, or non-parametric Mann-Whitney U test, and Wilcoxon signed rank test were used for comparison of continuous data between the two groups. The χ2 test, or Fisher's exact probability method, was used for comparing count data between the two groups. Results:There were statistically significant differences in age, gender, and HBsAg at baseline, but there was no statistically significant difference in terms of family history of hepatitis B, follow-up time, anti-HBe, anti-HBc, HBV DNA, ALT, aspartate aminotransferase (AST), albumin (Alb), and LSM between the two groups. There were statistically significant differences in HBsAg, anti-HBc, and ALT levels before and after follow-up in the low HBsAg group, but no statistically significant differences in anti-HBe, HBV DNA, AST, Alb, and LSM levels. There were statistically significant differences in HBsAg and anti-HBc before and after follow-up in the high HBsAg group, but no statistically significant differences in anti-HBe, HBV DNA, ALT, AST, Alb, and LSM. A liver biopsy was performed in 66 patients during follow-up, and 27.27% of the patients had moderate liver damage. In the low HBsAg group, 45.76% of patients had a HBsAg decrease rate of ≥0.5 log 10IU/ml, 10.17% of patients had HBV DNA negative conversion, 88.14% of patients had a persistently normal ALT, and 96.61% of patients had a persistently normal LSM at the end of follow-up. In the high HBsAg group, 3.75% of patients had a HBsAg decrease of ≥0.5 log 10IU/ml, no patient had a HBV DNA negative conversion, 90% of patients had a persistently normal ALT, and 98.75% of patients had a persistently normal LSM. There were statistically significant differences in the HBsAg decrease rate (45.76% vs. 3.75%, χ2=32.975, P＜0.001) and HBV DNA negative conversion rate (10.17% vs. 0, χ2=6.219, P=0.013) between the two groups at the end of follow-up, but there were no statistically significant differences in the persistently normal ALT and LSM rates. Conclusion:The vast majority of patients with HBeAg-negative chronic HBV infection in the indeterminate phase with low viral load had persistent hypoviremia over the long term. Some patients have liver tissue damage and may progress to cirrhosis and liver cancer as a result of HBV DNA positivity, so antiviral treatment should be initiated in all.
