Objectives: . The necessity to develop a method for prognostication and to identify novel biomarkers for personalized medicine in patients with head and neck squamous cell carcinoma (HNSCC) cannot be overstated. Recently, pathomics, which relies on quantitative analysis of medical imaging, has come to the forefront. CXCL8, an essential inflammatory cytokine, has been shown to correlate with overall survival (OS). This study examined the relationship between CXCL8 mRNA expression and pathomics features and aimed to explore the biological underpinnings of CXCL8. Methods: . Clinical information and transcripts per million mRNA sequencing data were obtained from The Cancer Genome Atlas (TCGA)-HNSCC dataset. We identified correlations between CXCL8 mRNA expression and patient survival rates using a Kaplan-Meier survival curve. A retrospective analysis of 313 samples diagnosed with HNSCC in the TCGA database was conducted. Pathomics features were extracted from hematoxylin and eosin–stained images, and then the minimum redundancy maximum relevance, with recursive feature elimination (mRMR-RFE) method was applied, followed by screening with the logistic regression algorithm. Results: . Kaplan-Meier curves indicated that high expression of CXCL8 was significantly associated with decreased OS. The logistic regression pathomics model incorporated 16 radiomics features identified by the mRMR-RFE method in the training set and demonstrated strong performance in the testing set. Calibration plots showed that the probability of high gene expression predicted by the pathomics model was in good agreement with actual observations, suggesting the model’s high clinical applicability. Conclusion . The pathomics model of CXCL8 mRNA expression serves as an effective tool for predicting prognosis in patients with HNSCC and can aid in clinical decision-making. Elevated levels of CXCL8 expression may lead to reduced DNA damage and are associated with a pro-inflammatory tumor microenvironment, offering a potential therapeutic target.

Objective:To explore the contents and methods of clinical comprehensive evaluation of microecologics, with the example of Bifidobacterium quadruple viable tablet, in order to provide evidence for clinical rational use of microecologics, and microecologics research, development and related decision-making, and to promote rational use of medications. Methods:Based on the research data collected from systematic literature search, health technology assessment methods such as evidence-based medicine and pharmacoeconomics evaluation were used to estimate the safety, efficacy, economics, suitability, accessibility and innovation of Bifidobacterium quadruple viable tablet. Results:In terms of efficacy, Bifidobacterium quadruple viable tablet showed significant therapeutic effects in the treatment of pediatric diarrhea, antibiotic-related diarrhea, diarrhea-predominant irritable bowel syndrome, and secondary diarrhea caused by diseases such as ulcerative colitis, as well as constipation and functional dyspepsia. It can also be used in the treatment of various diseases such as Helicobacter pylori related gastritis, liver cirrhosis, non-alcoholic fatty liver disease. In terms of safety, the incidence of adverse effects of this medication was low, and most were mild to moderate and transient symptoms. In terms of economics, compared with mesalazine alone in the treatment of ulcerative colitis, the incremental cost-effectiveness ratio of combination of Bifidobacterium quadruple viable tablet and mesalazine was 1 743.2. Besides, the daily treatment cost of Bifidobacterium quadruple viable tablet was lower than that of combination of Bifidobacterium triple viable and Bacillus licheniformis (1.87 to 2.80 yuan vs. 2.08 to 5.78 yuan). In terms of innovation, this medication had multiple patents and had been identified as a high-tech product in Zhejiang Province. In terms of suitability, the overall suitability of use and technical characteristics of medication were good. It could be further improved in the aspects of dosage form and system. In terms of accessibility, the price of the medication was stable, affordable and accessible to the general public. Conclusions:Based on the existing evidence, Bifidobacterium quadruple viable tablet presented effective with supported evidences, good safety, accessibility and innovation. The suitability can be further optimized. However, more in-depth and targeted research is needed in terms of economics and innovation in different clinical applications, and there is space for optimization in medication suitability.

Objective:To systematically analyze and integrate the real experience of puerpera in free delivery positions.Methods:Qualitative or mixed method studies on attitudes and emotional experiences of puerpera towards free delivery positions were retrieved through computer on PubMed, ScienceDirect, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, and WanFang Data. The search period was from database establishment to November 30, 2022. The quality of literature was evaluated using the quality evaluation criteria for qualitative research of the Joanna Briggs Institute Evidence-Based Health Care Center in Australia. The aggregation integration method was used to integrate the results.Results:A total of 5 articles were included and 28 results were extracted. The results were summarized into 10 categories, and 3 integrated results were formed, including factors that affected the choice of delivery position, the complex delivery experience of the puerpera, and the hope for much support.Conclusions:Hospitals, communities, and families should fully understand women's emotional experiences and needs for free delivery positions, provide sufficient support and guidance, and provide a reference basis for developing a reasonable delivery position plan and promoting a positive delivery experience.

Objective:To conduct interviews from the perspective of caregivers of children with autism spectrum disorders (ASD) and to conduct a multi-level and multi-dimensional strategy to provide help for families of children with ASD by exploring the experience of oral health care of such children.Methods:Using the purposive sampling method, a total of 11 family caregivers of children with ASD aged 12 and below who visited Outpatient Department of Pediatric Dental Prevention in Affiliated Stomatological Hospital of Nanjing Medical University from May 2020 to May 2021 were selected for semi-structured interviews. The subject was finally determined using Colaizzi's 7-step analysis method and assisted by Nvivo 12 software.Results:The current situation of oral care for children with ASD had three themes, namely, caregiver emotion, care dilemma and needs.Conclusions:More attention should be paid to the mental health of family caregivers with ASD. The oral health of children with ASD not only needs family caregivers, but also needs the common attention and support of the whole society, including multi-disciplinary and multi-department, to provide effective oral health management programs for children with ASD, so as to promote the oral health of this group of children.

Objective:To investigate the clinical features and prognosis of extranodal nasal-type NK/T-cell lymphoma of the extra-upper aerodigestive tract (extra-UADT NKTCL).Methods:The clinical data of 159 patients with extra-UADT NKTCL from the China Lymphoma Collaborative Group (CLCG) database between November 2001 and December 2015 were retrospectively analyzed. Kaplan-Meier survival analysis and Log-rank test were used to evaluate the prognosis. The Cox regression model is used for multi-factor analysis.Results:Extra-UADT NKTCL commonly occurs in skin and soft tissues (106/159, 66.7%) and gastrointestinal tract (31/159, 19.5%). The incidences of elevated lactate dehydrogenase (LDH) and Ann Arbor Ⅲ~Ⅳ stage were 47.8% (76/159) and 64.2% (102/159), respectively. The 3-year overall survival (OS) and progression-free survival (PFS) rates were 43.6% and 27.9%, respectively. The corresponding OS rates of primary skin/soft tissue site and gastrointestinal tract site were 41.0% and 59.4% ( P=0.281), while the PFS rates were 24.8% and 48.3%, respectively ( P=0.109). Combined modality treatment improved the 3-year OS of all the patients (58.4% vs 33.9%, P=0.001) and 3-year PFS (40.7% vs 20.7%, P=0.008) when compared with chemotherapy alone. LDH elevation, Ann Arbor synthesising and ≥2 junction external bits were intrusive as independent risk factors for total survival ( P<0.05), LDH elevation and ≥2 junction outer bits were intrusive as independent risk factors for progressionless survival( P<0.05). The distant extranodal dissemination was the primary failure patterns. Conclusions:Extra-UADT NKTCL appears to have distinct clinical characteristics and poor outcome. Compared with chemotherapy alone, combined modality treatment may improve the prognosis of patients with extra-UADT NKTCL.

Objective:To evaluate the prognosis and determine the failure patterns after radiotherapy for low-risk early-stage patients with extranodal NK/T-cell lymphoma, nasal-type (ENKTCL).Methods:A total of 557 patients from 2000—2015 with low-risk early-stage ENKTCL who received radiotherapy (RT) with or without chemotherapy (CT) from China Lymphoma Collaborative Group were retrospectively reviewed. Among them, 427 patients received combined modality therapy, whereas 130 patients received RT alone. Survivals were calculated by Kaplan-Meier method and compared with Log-rank test. Overall survival (OS) was compared with age and sex-matched general Chinese population using expected survival and standardized mortality ratio (SMR). Cox stepwise regression model was used for multivariate analysis.Results:The 5-year OS and progression-free survival (PFS) were 87.2% and 77.2%. The SMR was 3.59 ( P<0.001) at 1 year after treatment, whereas it was 1.50 at 4 years after treatment, without significant difference between ENKTCL group and country-matched general population ( P=0.146). Compared with RT alone, CMT did not result in significantly superior 5-year OS (87.0% vs 87.4%, P=0.961) or PFS (76.1% vs 80.7%, P=0.129). Local failure (11.5%, 64/557) and distant failure (10.8%, 60/557) were the main failure modes, while regional failure was rare (2.9%, 16/557). The 5-year locoregional control rate (LRC) was 87.2% for the whole group, with 89.5% for ≥50 Gy versus 73.7% for <50 Gy ( P<0.001). Radiotherapy dose was an independent factor affecting LRC( P<0.05). Conclusions:Radiotherapy achieves a favorable prognosis in patients with low-risk early-stage ENKTCL. The incidence of either locoregional or distant failure is low. Radiation dose still is an important prognostic factor for LRC.

Objective: To analyze the clinical characteristics of hepatic flare and evaluate efficacy of antiviral treatment in pregnant women with chronic HBV infection. Methods: A single-center, open-label, prospective study was conducted, and pregnant women with chronic HBV infection were enrolled. Liver function, HBV serum markers and HBV DNA of pregnant women with chronic HBV infection were reviewed during every 4 to 12 weeks of gestation period. The proportion and clinical characteristics of hepatitis flare during pregnancy were observed. Logistic regression analysis was used to predict hepatic flare in pregnant women with chronic HBV infection. Antiviral therapy with telbivudine (LdT) or tenofovir dipivoxil (TDF) was used to treat hepatic flare during pregnancy. Sequential entecavir (ETV) or TDF was applied after the delivery. Treatment course and drug withdrawal in pregnant women with hepatic flare was the same as those of the general patients with chronic hepatitis B. Liver function, HBV serum markers and HBV DNA were measured in pregnant women with hepatic flare at different time points (4, 12, 24 and 52 weeks). A t-test was used to compare the hepatic flare in pregnant women with and without hepatitis group. HBsAg and HBeAg were used to quantify the receiver operating characteristic (ROC) curve of pregnant women with hepatic flare during pregnancy. Area under the ROC curve was used to calculate the optimal cut-off value corresponding to the maximum sensitivity and specificity of the ROC curve. Results: Of the 220 pregnant women with chronic HBV infection, 55 (25%) had hepatitis flare during pregnancy and received antiviral treatment. Among the 55 women with hepatic flare during gestation, 47 (85.46%) had hepatic flare in the mid-second trimester (12-24 weeks); average peak value of alanine aminotransferase (ALT) was 220.62 U/L, and the average peak value of ALT in 32 cases (58.18%) of pregnant women with hepatic flare was between 2–5 × ULN. HBsAg and HBeAg quantification were significantly lower in pregnant women with hepatic flare during pregnancy than with non-hepatitis (t = -3.745, P < 0.001; t = -2.186, P = 0.030). Multivariate logistic regression analysis showed that pregnant women with HBeAg < 3.065 log10 s/co were 7.576 times more likely to have hepatic flare during pregnancy (95% confidence interval: 3.779-15.190). ALT normalization, undetectable HBV DNA levels, HBeAg loss and HBeAg seroconversion in 55 pregnant women with hepatic flare at 52-week treatment was 100% (55/55), 74.55% (41/55), 47.27% (26/55) and 41.82% (23/55), respectively. HBsAg quantification at 52 weeks was significantly lower than baseline HBsAg quantification (3.32 + 0.37) log₁₀ IU/ml and (3.95 + 0.40) log₁₀ IU/ml; t = 8.465, P < 0.001). Conclusion Hepatic flare often occurs in the second trimester of pregnancy in pregnant women with chronic HBV infection and baseline HBeAg quantification is an independent predictor of hepatic flare. HBeAg seroconversion rate increased at 52 weeks after antiviral therapy.

Objective To evaluate the prognostic value of anemia in patients diagnosed with extranodal nasal-type natural killer (NK)/T cell lymphoma (NKTCL).Methods Clinical data of 1 225 NKTCL patients receiving the first course of treatment from 10 medical institutions in China were retrospectively analyzed.According to the diagnostic criteria in China,anemia was defined as the hemoglobin (Hb) level＜ 120 g/L for the male and＜ 110 g/L for the female from the sea-level area.The severity of anemia was classified into the extremely severe anemia (Hb ≤ 30 g/L),severe anemia (31-60 g/L),moderate anemia (61-90 g/L) and mild anemia (＞90 g/L).Results Among 1 225 patients,199(16.2％) were complicated with anemia,who had more adverse prognostic factors compared with their counterparts without anemia.Among NKTCL patients with anemia,the proportion of patients with stage Ⅱ-ⅣV,a median age＞ anemia,Eastern Cooperative Oncology Group (ECOG) score of 2-4 and NK/T-cell lymphoma prognostic index (NKTCLPI) ≥ 2 was relatively high.Patients with anemia obtained worse clinical prognosis than those without anemia.The 5-year overall survival (OS) and progression-free survival (PFS) in NKTCL patients with anemia were calculated as 49.4％ and 35.4％,significantly lower compared with 63.3％ and 56.0％ in their counterparts without anemia (both P＜0.01).Single factor analysis demonstrated that anemia,age,ECOG score,group B symptom,lactate dehydrogenase,primary tumor site,primary tumor invasion and staging were the prognostic factors of OS and PFS.Multivariate analysis revealed that anemia was still the independent prognostic factor.Conclusions Anemia is not common in patients with NKTCL and these patients obtain poor clinical prognosis.Anemia is an independent prognostic factor for patients with NKTCL.
