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 construct a standard index system for the outpatient job competency of midwife, and to clarify the midwives' abilities when providing outpatient services, so as to improve the midwives' core competencies and service satisfaction.Methods:A research group was established in December 2018. On the basis of literature review and survey of midwives' outpatient needs in the early stage, referring to expert opinions, and taking job competency theory as the theoretical framework, the standard index system for the outpatient job competency of midwife were initially constructed. From December 2018 to March 2019, convenience sampling was used to select 24 experts from different ClassⅢ Grade A hospitals of Beijing, and the Delphi method was used to conduct 2 rounds of expert consultations.Results:Among 2 rounds of expert consultations, the effective recovery rates of the questionnaires were all 100.0% (24/24) , the positive coefficient of experts was 100.0%, and the coefficient of authority of experts was 0.786. The Kendall coordination coefficients of the 2 rounds of correspondence were 0.030 and 0.400, respectively ( P<0.05) . The final construction of standard index system for the outpatient job competency of midwife included 4 first-level indicators, 9 second-level indicators and 24 third-level indicators of knowledge and skills, professional quality, health education ability, and ability to improve the quality of professional services. Conclusions:The standard index system for the outpatient job competency of midwife is scientific and reasonable, comprehensive in content, and strong in specialty, which can provide a reference for the training and assessment of midwife.

Objective: Comparing the benefit of Abidor, lopinavir/ritonavir and recombinant interferon α-2b triple combination antiviral therapy and lopinavir/ritonavir and interferon dual combination antiviral therapy to hospitalized novel coronavirus pneumonia 2019 in Zhejiang province. Methods: A multi-center prospective study was carried out to compare the effect of triple combination antiviral therapy with dual combination antiviral therapy in 15 medical institutions of Zhejiang Province. All patients were treated with recombinant interferon α-2b (5 million U, 2 times/d) aerosol inhalation. 196 patients were treated with abidol (200 mg, 3 times/d) + lopinavir / ritonavir (2 tablets, 1 time/12 h) as the triple combination antiviral treatment group. 41 patients were treated with lopinavir / ritonavir (2 tablets, 1 time/12 h) as the dual combination antiviral treatment group. The patients who received triple combination antiviral therapy were divided into three groups: within 48 hours, 3-5 days and > 5 days after the symptom onset. To explore the therapeutic effects of triple combination antiviral drugs and dual combination antiviral drugs, as well as triple combination antiviral drugs with different antiviral initiate time. SPSS17.0 software was used to analyze the data. Results: The time of virus nucleic acid turning negative was (12.2 ± 4.7) days in the triple combination antiviral drug group, which was shorter than that in the dual combination antiviral drug group [(15.0 ± 5.0) days] (t = 6.159, P < 0.01 ). The length of hospital stay [12 (9, 17) d] in the triple combination antiviral drug group was also shorter than that in the dual combination antiviral drug group [15 (10, 18) d] (H = 2.073, P < 0.05). Comparing the antiviral treatment which was started within 48 hours, 3-5 days and > 5 days after the symptom onset of triple combination antiviral drug group, the time from the symptom onset to the negative of viral shedding was 13 (10,16.8), 17 (13,22) and 21 (18-24) days respectively (Z = 32.983, P < 0.01), and the time from antiviral therapy to the negative of viral shedding was (11.8±3.9) , (13.5±5.1) and (11.2±4.3) d. The differences among the three groups were statistically significant (Z=32.983 and 6.722, P<0.01 or<0.05). Conclusions The triple combination antiviral therapy of Abidor, Lopinavir/Litonavir and recombinant interferon α-2b showed shorter viral shedding time and hospitalization time compared with the dual combination antiviral therapy. The earlier the time to initiate triple antiviral treatment, the shorter the time of virus shedding.

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 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 To explore the diagnostic value of tumor necrosis factor-alpha (TNF-α) , interleukin-6 (IL-6) and neuron enolase (NSE) in the cerebrospinal fluid of children with central nervous sys-tem infection (CNSI).Methods 54 cases of CNSI hospitalized children ,admitted in the hospital from October 2015 to January 2017 ,were enrolled in the study and divided into viral meningitis group (30 cases) and suppu-rative meningitis group (24 cases).Another 20 cases who underwent cerebrospinal fluid examination and other related examinations were enrolled in the study as the control group.The levels of three biomarkers TNF-α , IL-6 and NSE in cerebrospinal fluid of three groups were detected by enzyme linked immunosorbent assay (ELISA).Results The levels of TNF-α ,IL-6 and NSE in purulent meningitis group were the hightest ,and the levels of these three factors in viral meningitis group were highter than the control group ,and the differ-ence was statistically significant in three groups (P＜0.05).But there were a lot of data overlaps.There was no significant difference in the levels of TNF-α ,IL-6 and NSE between the brain group and the control group (P＞0.05).Conclusion The detection of TNF-α ,IL-6 and NSE in cerebrospinal fluid has a certain clinical val-ue for the diagnosis of CNSI ,but it needs to be further verified by a large sample clinical trial.

Objective To evaluate the diagnostic value and safety of endobronchial ultrasoundguided transbronchial needle aspiration (EBUS-TBNA) in elderly patients with bronchogenic carcinoma.Methods From August,2013 and July,2014,31 patients aged 65 years and over with space-occupying mass and enlarged mediastinal lymph nodes detected by CT or positron emission tomography-computed tomography (PET-CT) underwent EBUS-TBNA.Rapid onsite cytology evaluation was not performed.Results There were 26 males and 5 females in this study,aged 65-77 years (70.1 years old on average).In 31 patients,70 samples were obtained from lymph nodes (LNs) and 4 samples were obtained from intrapulmonary lesions.29 cases were diagnosed as lung cancer,and 2 cases had false-negative diagnoses.The sensitivity and specificity rates of EBUS-guided TBNA method were 93.6％ and 100.0％,respectively.No major complications were observed in this series.Conclusions EBUS-TBNA is an safe and effective method in diagnosing bronchogenic carcinoma in elderly patients.
