Cryoablation therapy with explicit anti-tumor mechanisms and histopathological manifestations has a long history.A large number of clinical practice has shown that cryoablation therapy is safe and effective,making it an ideal tumor treatment method in theory.Previously,its efficacy and clinical application were constrained by the limitations of refrigerants and refrigeration equipment.With the development of the new generation of cryoablation equipment represented by argon helium knives,significant progress has been made in refrigeration efficien-cy,ablation range,and precise temperature measurement,greatly promoting the progression of tumor cryoablation technology.This consensus systematically summarizes the mechanism of cryoablation technology,indications for oral mucosal melanoma(OMM)cryotherapy,clinical treatment process,adverse reactions and management,cryotherapy combination therapy,etc.,aiming to provide reference for carrying out the standardized cryoablation therapy of OMM.

ObjectiveTo evaluate the effectiveness and safety of Qiaoqi Formula （翘芪组方） for mild influenza. MethodsA randomized controlled study was designed， recruiting 74 patients with mild influenza， who were randomly divided into trial group and control group. The trial group took Qiaoqi Formula orally， 40ml each time， twice a day； the control group took Lianhua Qingwen Capsules （连花清瘟胶囊） orally， 1.4 g each time， three times a day. Both groups were treated for 3 consecutive days and follow-up for 4 consecutive days after treatment. The time for fever reduction including onset of fever reduction， complete fever reduction time， fever reduction rates at 24， 48 and 72 hours， improvement of influenza symptoms， total traditional Chinese medicine （TCM） symptom score， and safety indicators in two groups after treatment were recorded. ResultsSixty-five patients were ultimately included， including 36 in the trial group and 29 in the control group. Onset time of fever reduction in the trial group was （15.49±23.47） h， the complete fever reduction time （21.37±30.06）h， and the 24 h， 48 h， 72 h， fever reduction rate was 77.14%， 88.57%， 91.42% respectively. The above indicators of the control group showed as （17.58±20.38）h， （24.30±21.87）h， 61.29%， 90.32%， 96.77% respectively， with no statistically significant differences （P＞0.05）. On the 7th day after treatment， the total score of TCM syndromes in trial group and control group decreased compared to those before treatment （P＜0.05）. There was no statistically significant difference in the cure rate， significant effective rate， effective rate， and total effective rate of TCM syndromes between groups （P＞0.05）. On the 4th day， the lymphocyte ratio of patients in the control group was higher than before treatment， while alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， urea， and creatinine of both groups before and after treatment were within the normal range. The main adverse reactions in both groups were mild headache and dizziness， and no serious adverse reactions observed. ConclusionThe therapeutic effect of Qiaoqi Formula in treating mild influenza is equivalent to Lianhua Qingwen Capsules， which can shorten the fever reduction time， improve clinical symptoms， and no adverse events observed during the study.

Objective To investigate the impact of exosomal miRNAs derived from endoplasmic reticulum-stressed(ERS)head and neck squamous cell carcinoma(HNSCC)cells on macrophages.Methods This study was reviewed and approved by the Ethics Committee.The expression levels of ERS-associated proteins,including protein kinase R-like endoplasmic reticulum kinase(PERK)and glucose-regulated protein 78(GRP78),in HNSCC tissues and para-tumor tissues were detected by Western blot(WB)and quantitative real-time PCR(RT-qPCR).HN4 human laryngeal squamous cell carcinoma cells were treated with 500 U/mL interferon-γ(IFN-γ)for 48 h to induce ER stress,and exo-somes secreted by ER-stressed HN4 cells were collected and identified.The types of miRNAs in exosomes were identi-fied through bioinformatics analysis,and the target genes of miRNAs were predicted.Macrophages were transfected with miRNA,co cultured with collected exosomes,and the expression of PTEN in macrophages was knocked down.The downstream signaling pathway regulated by exosomal miRNAs was studied by WB and RT-qPCR.Results Compared with that in para-tumor tissues,the expression level of ER stress-associated proteins in HNSCC tissues was increased(P＜0.05).RNA-seq analysis revealed that miR-26a-5p was highly upregulated in ER-stressed HN4 cell-derived exo-somes(P＜0.05).PTEN is the target gene for miR-26a-5p.miR-26a-5p increased the expression level of PD-L1 in mac-rophages and downregulated the expression of PTEN(P＜0.05).Macrophages co cultured with ERS extracellular vesi-cles showed an increase in miR-26a-5p and PD-L1 expression,a decrease in PTEN expression,and an increase in p-AKT expression(P＜0.05).Knock down the expression of PTEN in macrophages and increase the expression of PD-L1(P＜0.01).Conclusion ERS HNSCC cell-derived exosomal miR-26a-5p promotes the expression of PD-L1 in macro-phages through the PTEN/AKT signaling pathway.

The biological clock(also known as the circadian rhythm)is the fundamental reliance for all organisms on Earth to adapt and survive in the Earth's rotation environment.Circadian rhythm is the most basic regulatory mechanism of life activities,and plays a key role in maintaining normal physiological and biochemical homeostasis,disease occurrence and treatment.Recent studies have shown that the biologi-cal clock plays an important role in the development of oral tissues and in the occurrence and treatment of oral diseases.Since there is cur-rently no guiding literature on the research methods of biological clock in stomatology,researchers mainly conduct research based on pub-lished references,which has led to controversy about the research methods of biological clock in stomatology,and there are many confusions about how to rationally apply the research methods of circadia rhythms.In view of this,this expert consensus summarizes the characteristics of the biological clock and analyzes the shortcomings of the current biological clock research in stomatology,and organizes relevant experts to summarize and recommend 10 principles as a reference for the rational implementation of the biological clock in stomatology research.

Objective:To evaluate the efficacy and safety of immunotherapy with or without radiotherapy in the treatment of recurrent or metastatic esophageal squamous cell carcinoma (R/M ESCC).Methods:A retrospective analysis was conducted on the data of 75 patients with R/M ESCC treated with sintilimab at Anyang Tumor Hospital from January 2020 to October 2021. The patients were divided into the radiotherapy (RT) group ( n=37) and non-radiotherapy (NRT) group ( n=38) based on whether they received radiotherapy. The objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and adverse effects were compared between two groups. Count data were expressed as composition ratios and analyzed using Chi-square test or Fisher's exact test. Survival analysis was performed using Kaplan-Meier method and log-rank test. Results:There was no statistically significant difference in ORR and DCR between the RT and NRT groups (70% vs. 61%, P=0.375; 95% vs. 89%, P=0.414). However, the complete response (CR) rate in the RT group was higher compared to that in the NRT group (19% vs. 3%, P=0.022). The median follow-up duration was 25.4 months. There was no statistically significant difference in the median PFS and OS between the RT and NRT groups (13.8 months vs. 9.9 months, P=0.221; 20.2 months vs. 18.9 months, P=0.214). Subgroup analysis demonstrated that among patients with recurrence or metastasis confined to local and / or ≤3 distant lymph nodes, there was no statistically significant difference in the median PFS between the RT and NRT groups (15.1 months vs. 8.4 months, P=0.115), but the median OS in the RT group was better than that in the NRT group (not reached vs. 12.3 months, P=0.036). Compared to the NRT group, besides an increase in grade 1-2 pneumonitis (41% vs. 18%, P=0.035), no significant increase in treatment-related toxicity was observed in the RT group. Conclusion:Immunotherapy combined with radiotherapy is safe in patients with R/M ESCC, and shows survival benefit in patients with recurrence or metastasis confined to local and / or ≤3 distant lymph nodes.

Objective To analyze the correlation between the drug resistance rate of common pathogens in blood culture of inpatients from the First Hospital Affiliated to Hebei North University from 2019 to 2021 and the frequency of antimicrobial drug use (DDDs). Methods Strains isolated from positive blood cultures of inpatients from 2019 to 2021 were collected, and data on antimicrobial drug use in patients with positive blood cultures during the same period were also collected. WHONET 5.6 software and Pearson correlation analysis were used to explore the correlation between pathogenic bacterial resistance rate and antimicrobial DDDs. Results A total of 916 samples tested positive in blood cultures from 2019 to 2021. Among the top antimicrobial drugs in DDDs, the DDDs of cefazolin, cefuroxime, and ceftazidime all showed an upward trend year by year (the increase from 2019 to 2021 was 38.8%, 228.3%, and 87.1%, respectively). A total of 739 pathogenic bacteria strains were isolated from positive blood culture samples from 2019 to 2021, and the top five pathogenic bacteria were Escherichia coli, Klebsiella pneumoniae, Staphylococcus epidermidis, Staphylococcus aureus, and Pseudomonas aeruginosa, accounting for 37.2%, 16.1%, 8.1%, 7.4%, and 6.5%, respectively. The drug resistance rates of Escherichia coli to cefazolin, ceftazidime, cefotaxime, and polymyxin B were positively correlated with their DDDs (r=0.961, 0.907, 0.988, 0.997, P < 0.05). The drug resistance rates of Klebsiella pneumoniae to piperacillin, cefazolin, cefotaxime, cefepime, aztreonam, imipenem, meropenem, levofloxacin, and polymyxin B were positively correlated with their DDDs (r=0.766, 0.772, 0.838, 0.667, 0.734, 0.821, 0.904, 0.980, 0.997, P < 0.05). The drug resistance rate of Pseudomonas aeruginosa to gentamicin was positively correlated with their DDDs (r=0.878, P < 0.05). The drug resistance rate of Acinetobacter baumannii to moxifloxacin was positively correlated with its DDDs (r=0.856, P < 0.05). However, there was no correlation between the drug resistance rates of Staphylococcus aureus and Staphylococcus epidermidis to most commonly used antimicrobial drugs and antimicrobial DDDs (P>0.05). Conclusion The pathogenic bacteria causing bloodstream infections in inpatients at the First Hospital Affiliated to Hebei North University from 2019 to 2021 are complex and diverse (mainly Gram-negative bacteria). The overall drug resistance rate of pathogenic bacteria shows an upward trend, and there is a correlation between the drug resistance rates of most pathogenic bacteria and antimicrobial DDDs.

The conventional approach to investigating functional connectivity in the block-designed study usually concatenates task blocks or employs residuals of task activation. While providing many insights into brain functions, the block design adds more manipulation in functional network analysis that may reduce the purity of the blood oxygenation level-dependent signal. Recent studies utilized one single long run for task trials of the same condition, the so-called continuous design, to investigate functional connectivity based on task functional magnetic resonance imaging. Continuous brain activities associated with the single-task condition can be directly utilized for task-related functional connectivity assessment, which has been examined for working memory, sensory, motor, and semantic task experiments in previous research. But it remains unclear how the block and continuous design influence the assessment of task-related functional connectivity networks. This study aimed to disentangle the separable effects of block/continuous design and working memory load on task-related functional connectivity networks, by using repeated-measures analysis of variance. Across 50 young healthy adults, behavioral results of accuracy and reaction time showed a significant main effect of design as well as interaction between design and load. Imaging results revealed that the cingulo-opercular, fronto-parietal, and default model networks were associated with not only task activation, but significant main effects of design and load as well as their interaction on intra- and inter-network functional connectivity and global network topology. Moreover, a significant behavior-brain association was identified for the continuous design. This work has extended the evidence that continuous design can be used to study task-related functional connectivity and subtle brain-behavioral relationships.

Objective:To investigate the iodine nutritional level of residents in iodine adequate areas in Henan Province, and provide basis for making policy of targeted guidance and rational iodine supplementation.Methods:In the 156 counties of Henan Province in 2020, one township was selected from each location (east, west, south, north and middle) in each county; one school was selected from each township; 40 children aged 8-10 years in the school and 20 pregnant women in the township were selected to collect their urine and salt samples to test urine and salt iodine levels. One third of the counties were selected to examine the thyroid gland of children. Individuals lived in villages with water iodine between 40 and 100 μg/L were included in the study.Results:In iodine adequate areas, a total of 2 097 salt samples were collected from children and tested, the consumption rate of qualified iodized salt was 93.6% (1 962/2 097). A total of 2 096 urine samples were collected from children and tested, and the median urinary iodine was 288.0 μg/L. The goiter rate of children was 0.7% (5/723). A total of 1 068 salt samples from pregnant women were tested, and the consumption rate of qualified iodized salt was 93.0% (993/1 068). A total of 1 068 urine samples from pregnant women were tested, with a median urinary iodine 232.7 μg/L. Stratified by water iodine (40-59, 60-79, 80-100 μg/L), the median urinary iodine of children was 273.8, 288.6, and 305.9 μg/L, respectively, statistically significantly different between groups ( H = 15.79, P < 0.001); the goiter rate of children was ≤2%, and the difference between groups was statistically significant (χ 2 = 7.31, P = 0.026); but the median urinary iodine of pregnant women was not significantly different ( H = 1.82, P = 0.402). Under different water iodine conditions, there was no significant difference in urinary iodine levels in children and pregnant women between the high salt iodine concentration group (≥21 mg/kg) and the low salt iodine concentration group (< 21 mg/kg, P > 0.05). Conclusions:The iodine nutrition level of children in iodine adequate areas in Henan Province is relatively high, and the iodine nutrition of pregnant women is appropriate. The goiter rate of children is at a relatively low level. Continuous surveillance should be conducted to comprehensively evaluate the iodine nutrition level. Various measures will be taken by regions and populations.

Objective:To compare the coverage rate of non-iodized salts, children's iodine nutrition and the change trend of goiter rate between the original water source high iodine areas in Henan Province in 2017 and the newly designated water source high iodine areas in 2019.Methods:Using a cross-sectional survey method, household edible salt monitoring was conducted in all 20 counties (cities, districts) with high iodine content in Henan Province in 2017. Ten counties (cities, districts) were selected to monitor water iodine, urinary iodine and thyroid volume of children aged 8 to 10 years. A total of 4 430 salt samples and 1 012 urine samples were collected, and thyroid volume of 1 012 children were measured. In 2019, monitoring of household edible salt, water iodine, urinary iodine, and thyroid volume was carried out in all 55 newly designated counties (cities, districts) with high iodine village. A total of 9 835 salt samples and 9 830 urine samples were collected, and the thyroid volume of 8 896 children was measured. The monitoring results of two years were compared, and the relationship between children's urinary iodine and goiter rate was analyzed by univariate logistic regression.Results:In 2019, the water iodine content in newly designated high iodine areas decreased compared to the original high iodine areas in 2017 (119.8 to 191.0 μg/L), and the difference was statistically significant ( Z = - 2.48, P = 0.013). The rate of non-iodized salts in 2019 was only 35.5% (3 494/9 835), significantly lower than that in 2017 (96.2%, 4 263/4 430, χ 2 = 4 536.74, P < 0.001). The median urinary iodine of children in 2017 and 2019 were 338.2 and 317.8 μg/L, respectively, the difference between the two years was statistically significant ( Z = - 2.46, P = 0.014). In 2017 and 2019, the goiter rate of children aged 8 to 10 years was 1.5% (15/1 012) and 2.1% (187/8 896), respectively, and there was no significant difference between the two years (χ 2 = 1.76, P = 0.185). The results of univariate logistic regression analysis showed that, compared with the control group with urinary iodine < 100 μg/L, the risk of goiter rate (but the enlargement rate did not exceed 5%) increased with the increase of urinary iodine level (100 - 199, 200 - 299 and ≥300 μg/L groups), and the differences were statistically significant [odds ratio ( OR) = 8.64, 7.68, 10.69, P < 0.05]. Conclusion:After the implementation of the new demarcation standard for areas with excessive iodine in water sources, the supply of non-iodized salts in Henan Province is relatively lagging behind, and the iodine nutrition level of children is still high, but the goiter rate is relatively stable.

Objective:To evaluate the effect of health education project on prevention and control of endemic diseases in Henan Province.Methods:According to the distribution and condition of endemic diseases in Henan Province, from 2008 to 2015, five project counties (cities, districts, referred to as counties) were selected in each provincial city. Three townships (towns) were selected from each project county as project townships (towns), and one central primary school and the village where the school was located were selected from each township (town) as health education survey sites. The prospective study method was adopted. Firstly, the students in the primary school of the project township (town) and the housewives in the project village were investigated with questionnaire. The intervention activities of health education were carried out in the county, township (town), village and school of the project. The intervention effect of health education was evaluated by questionnaire survey two months later.Results:There were 111 870 people investigated in Henan Province, including 74 580 students and 37 290 housewives. A total of 99 671 people were surveyed after the intervention, including 66 249 students and 33 422 housewives. Elementary student's awareness rate of endemic diseases prevention and control knowledge increased from 59.74% before intervention to 92.89% after intervention, the housewives' awareness rate increased from 65.62% before intervention to 91.82% after intervention. The awareness rate of the target population increased from 61.70% before intervention to 92.53% after intervention ( P < 0.01); among them, the awareness rates of iodine deficiency disorders, drinking water type fluorosis, coal-burning type fluorosis, drinking water type arsenic poisoning, Kashin-Beck disease and Keshan disease were significantly increased ( P < 0.01). Conclusion:With the implementation of health education project, the awareness rate of knowledge on endemic diseases has increased distinctly.
