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.

Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Objective:To evaluate the efficacy of rhomboid inter-costal and sub-serratus (RISS) block with ropivacaine-dexmedetomidine-dexamethasone for analgesia after thoracoscopic lobectomy.Methods:This study was a prospective, randomized, double-blind, controlled trial. From January 2021 to November 2023, 46 American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients of either sex, undergoing elective video-assisted thoracoscopic lobectomy at the Second Affiliated Hospital of Nanjing Medical University, were selected and assigned into 2 groups ( n=23 each) using simple randomization: ropivacaine group (R group) and ropivacaine-dexmedetomidine-dexamethasone group (RDA group). RISS block was performed preoperatively, with 20 ml of the drug solution injected at the target points of the rhomboid-intercostal muscle and the serratus anterior-intercostal muscle. R group received 0.375% ropivacaine 40 ml, while RDA group received 40 ml of the mixture containing 0.375% ropivacaine, dexmedetomidine 1 μg/kg, and dexamethasone 8 mg. Postoperative analgesia was performed with oxycodone (When the patient′s numerical rating scale [NRS] score >4 in post-anesthesion care unit, oxycodone 2 mg was intravenously administered as needed until the NRS score <4, and then a patient-controlled analgesia pump was initiated). The time of the first postoperative analgesic requirement, NRS scores at rest and during coughing at 1, 3, 6, 12, 24 and 48 h postoperatively, cumulative consumption of oxycodone in the periods of 0-12 h, >12-24 h, and >24-48 h, time to first ambulation, and incidence of related adverse reactions within 48 h postoperatively were recorded. Results:Compared with R group, the time to the first analgesic requirement was significantly prolonged, the cumulative consumption of oxycodone in the first 0-12 h postoperatively was reduced ( P<0.001), and no statistically significant changes were found in the time to first ambulation, NRS scores at rest and during coughing, or the incidence of postoperative adverse reactions in RDA group ( P>0.05). Conclusions:RISS block using a combination of ropivacaine, dexmedetomidine and dexamethasone can significantly prolong block duration, reduce postoperative opioid analgesic consumption, and provide good safety for the patients undergoing thoracoscopic lobectomy.

Objective:To determine the median effective dose (ED 50) of oliceridine inhibiting the responses to the laryngeal mask airway insertion when combined with ciprofol in elderly patients. Methods:In this sequential trial, American Society of Anesthesiologists Physical Status classificationⅠ-Ⅲ elderly patients of either sex, aged ≥65 yr, with a body mass index of 18-30 kg/m 2, undergoing elective urological surgery under general anesthesia with laryngeal mask airway, were included in this study. Ciprofol 0.4 mg/kg was intravenously injected, the dose of oliceridine was determined by using modified Dixon′s up-and-down method (increment or decrement of 0.005 mg/kg), and the initial dose of oliceridine was 0.01 mg/kg. A positive response was defined as an increase in maximum mean arterial pressure or heart rate ≥20% within 3 min after inserting the laryngeal mask airway or occurrence of any one of these signs such as movement, coughing, frowning, mouth corner twitching, tearing, laryngospasm, or bispectral index value failing to drop below 60. The trial was terminated upon observing 7 positive-to-negative transition points, starting from the first occurrence of an alternation between positive and negative responses to laryngeal mask airway insertion. The ED 50 and 95% confidence interval of oliceridine inhibiting the responses to the laryngeal mask airway insertion was calculated when combined with ciprofol in elderly patients. Results:The ED 50 of oliceridine inhibiting the response to laryngeal mask airway insertion was 0.027 mg/kg, and the 95% confidence interval was 0.008-0.048 mg/kg when combined with ciprofol 0.4 mg/kg. Conclusions:The ED 50 of oliceridine inhibiting the response to laryngeal mask airway insertion is 0.027 mg/kg when combined with ciprofol 0.4 mg/kg in elderly patients.

Objective:To investigate the effects of wheat-grain moxibustion at the Guanyuan point on testosterone(T)synthe-sis and the hypothalamic-pituitary-gonadal(HPG)axis in naturally aged mice.Methods:We fed 40 twelve-month-old SPF male C57BL/6J mice with a normal diet for 3 months,randomized them into a moxibustion and an aged group of an equal number,and se-lected 7 four-month-old ones as young controls.We treated the animals of the moxibustion group by wheat-grain moxibustion at the Guanyuan point,once 5 moxibustion sticks,qd,5 times a week,and fed those of the aged group normally,all for 12 weeks.After treatment,we obtained the testicular index of the mice,observed the histomorphology of the testis tissue by HE staining,measured the contents of T in the testis,gonadotropin-releasing hormone(GnRH)in the hypothalamus and total T(tT),free T(fT),luteinizing hormone(LH)and follicle-stimulating hormone(FSH)in the serum by ELISA,and determined the expressions of silence information regulator-1(SIRT1),P53,glutathione peroxidase(GPX4)and cholesterol side-chain?cleavage enzym e(CYP11A1)in the testis by Western blot.Results:Compared with the young controls,the mice in the aged group showed obviously losing and dull hair,energy declination,loose structure of the spermatogenic tubule with different degrees of cell loss and rupture,reduced testicular index,and ev-ident aging phenotype.In comparison with the aged mice,the animals of the moxibustion group were fairly energetic and exhibited dis-tinct structure of the spermatogenic tubules,orderly arranged and highly differentiated cells at all levels,significantly increased T lev-el,up-regulated expressions of SIRT1,GPX4 and CYP11 A1,and down-regulated expression of P53 in testis tissue,and elevated levels of GnRH,FSH,LH,tT and fT in the HPG axis.Conclusion:Wheat-grain moxibustion at the Guanyuan point protects testosterone synthesis in the testis tissue of naturally aged mice,promotes negative feedback regulation of the HPG axis,and improves low testoster-one.

Objective:To explore potential predictors of refractory Mycoplasma pneumoniae pneumonia (RMPP) in early stage. Methods:The prospective multicenter study was conducted in Zhejiang, China from May 1 st, 2019 to January 31 st, 2020. A total of 1 428 patients with fever >48 hours to <120 hours were studied. Their clinical data and oral pharyngeal swab samples were collected; Mycoplasma pneumoniae DNA in pharyngeal swab specimens was detected. Patients with positive Mycoplasma pneumoniae DNA results underwent a series of tests, including chest X-ray, complete blood count, C-reactive protein, lactate dehydrogenase (LDH), and procalcitonin. According to the occurrence of RMPP, the patients were divided into two groups, RMPP group and general Mycoplasma pneumoniae pneumonia (GMPP) group. Measurement data between the 2 groups were compared using Mann-Whitney U test. Logistic regression analyses were used to examine the associations between clinical data and RMPP. Receiver operating characteristic (ROC) curves were used to analyse the power of the markers for predicting RMPP. Results:A total of 1 428 patients finished the study, with 801 boys and 627 girls, aged 4.3 (2.7, 6.3) years. Mycoplasma pneumoniae DNA was positive in 534 cases (37.4%), of whom 446 cases (83.5%) were diagnosed with Mycoplasma pneumoniae pneumonia, including 251 boys and 195 girls, aged 5.2 (3.3, 6.9) years. Macrolides-resistant variation was positive in 410 cases (91.9%). Fifty-five cases were with RMPP, 391 cases with GMPP. The peak body temperature before the first visit and LDH levels in RMPP patients were higher than that in GMPP patients (39.6 (39.1, 40.0) vs. 39.2 (38.9, 39.7) ℃, 333 (279, 392) vs. 311 (259, 359) U/L, both P<0.05). Logistic regression showed the prediction probability π=exp (-29.7+0.667×Peak body temperature (℃)+0.004×LDH (U/L))/(1+exp (-29.7+0.667×Peak body temperature (℃)+0.004 × LDH (U/L))), the cut-off value to predict RMPP was 0.12, with a consensus of probability forecast of 0.89, sensitivity of 0.89, and specificity of 0.67; and the area under ROC curve was 0.682 (95% CI 0.593-0.771, P<0.01). Conclusion:In MPP patients with fever over 48 to <120 hours, a prediction probability π of RMPP can be calculated based on the peak body temperature and LDH level before the first visit, which can facilitate early identification of RMPP.

BACKGROUND: Liver biopsy for the diagnosis of non-alcoholic steatohepatitis (NASH) is limited by its inherent invasiveness and possible sampling errors. Some studies have shown that cytokeratin-18 (CK-18) concentrations may be useful in diagnosing NASH, but results across studies have been inconsistent. We aimed to identify the utility of CK-18 M30 concentrations as an alternative to liver biopsy for non-invasive identification of NASH. METHODS: Individual data were collected from 14 registry centers on patients with biopsy-proven non-alcoholic fatty liver disease (NAFLD), and in all patients, circulating CK-18 M30 levels were measured. Individuals with a NAFLD activity score (NAS) ≥5 with a score of ≥1 for each of steatosis, ballooning, and lobular inflammation were diagnosed as having definite NASH; individuals with a NAS ≤2 and no fibrosis were diagnosed as having non-alcoholic fatty liver (NAFL). RESULTS: A total of 2571 participants were screened, and 1008 (153 with NAFL and 855 with NASH) were finally enrolled. Median CK-18 M30 levels were higher in patients with NASH than in those with NAFL (mean difference 177 U/L; standardized mean difference [SMD]: 0.87 [0.69-1.04]). There was an interaction between CK-18 M30 levels and serum alanine aminotransferase, body mass index (BMI), and hypertension ( P  < 0.001, P  = 0.026 and P  = 0.049, respectively). CK-18 M30 levels were positively associated with histological NAS in most centers. The area under the receiver operating characteristics (AUROC) for NASH was 0.750 (95% confidence intervals: 0.714-0.787), and CK-18 M30 at Youden's index maximum was 275.7 U/L. Both sensitivity (55% [52%-59%]) and positive predictive value (59%) were not ideal. CONCLUSION This large multicenter registry study shows that CK-18 M30 measurement in isolation is of limited value for non-invasively diagnosing NASH.
