Objective: To understand the oral health status and associated factors of preschool children with disabilities in Bengbu City, so as to provide evidence for preventing dental caries in children with disabilities. Methods: From September 2021 to March 2022, a total of 405 preschool children with disabilities from two rehabilitation institutions in Bengbu were randomly selected for oral health examination, questionnaire survey and physical examination. The caries prevalence rate among disabled children was analyzed. After grouping based on childrens BMI, the correlation between body mass index (BMI) and dental caries among children was explored. Multivariate binary Logistic regression analysis was employed to investigate the factors associated with dental caries occurrence in children. Results: The prevalence of dental caries in preschool children with disabilities was 74.07%, with rates of 71.01% for boys and 77.27% for girls. There was a significant difference in caries prevalence between boys and girls aged 5（66.67%，88.24%） (χ2=7.53, P<0.05). There were significant differences in the dmft index among different BMI groups (underweight: 240, normal weight: 606, overweight:30,obese:60,H=35.66,P<0.05). BMI was negatively correlated with dmft（r=-0.50，P＜0.01）. Frequent tooth brushing (2-3 times daily), the use of fluoride toothpaste, limited intake of sugary foods (< 2 times/d) in the past six months, and exclusively breastfeeding within first six months were negatively correlated with the occurrence of dental caries in disabled children (OR=0.09，0.41，0.24, P＜0.05). Sleep forward to eat，parental education level of junior high school or lower, and parental education of vocational school or high school were positively correlated with dental caries (OR=3.18，5.95，3.99，66.95，7.75，P＜0.05). Conclusions The caries prevalence rate of disabled children in Bengbu City is high and is influenced by multiple factors. It is time to strengthen the oral health training for parents and teachers in educational institutions, pay attention to childrens oral health care, and help disabled children improve their quality of life.

The abnormal characteristics and unacceptable Delta check of the specimens also need to be concerned at the same time.The false negative rate and false positive rate, true negative rate, true positive rate and pass correct rate of autoverification were verified and compared with the rate of the second phase verification when the autoverification rule was established. The false negative rate, false positive rate, true negative rate and true positive rate of the Delta check rule which 54 716 specimens touched were calculated and compared with the second phase verification rate when the autoverification rule was established.The results of microscopic examination were used as the gold standard for the calculation of the rates, and P<0.05 was considered as a significant difference. The false positive and true positive of 1 012 autoverification rules were analyzed item by item.The false positive and true positive of 108 specimens which touched blast cell autoverification rule were analyzed terms by terms. The mean TAT and median TAT of 528 010 specimens and 193 750 outpatient specimens were calculated respectively, and the report percentages of 528 010 samples that TAT<30, 30-60　and>60 min were calculated respectively. Analyze and evaluate the application suitability of autoverification rules to juge whether they meet the needs of doctors and laboratory. The design process and the rules and application process of autoverification were optimized and improved.Results:The autoverification pass rate was 63.06% (332 971/528 010), the interception rate was 36.94% (195 039/528 010). The false negative rate was 1.00% (1/600), the false positive rate was 12.67% (76/600), the true negative rate was 49% (294/600), the true positive rate was 37.33% (224/600), and the correct rate was 98% (294/300). The pass rate, true negative rate, true positive rate and correct rate of the periodic reverification group were higher than the second phase verification group, the false negative rate and false positive rate were lower than that the second phase verification group. The false negative rate and true positive rate of the Delta check of periodic verification group were lower than that the second phase verification group, the false positive rate and true negative rate were higher than the second phase verification group, there were significant differences in the comparition results. The mean TAT of 528 010 specimens was25 min, and the median TAT was 22 min. The mean TAT of 193 750 outpatient specimens was 23 min, and the median TAT was 20 min. The report percentages of 528 010 samples that TAT<30 min, 30 min-60 min and>60 min were 83.30% (439 819/528 010), 8.00% (42 250/528 010) and 8.70% (45 941/528 010), respectively.Conclusion:The results of periodic revalidation of autoverification after 1 years application show that the 15 items and 43 terms autoverification rules of blood analysis could meet requirements about the accuracy and efficiency of the laboratory, and have a good suitability for application.

Objective: To analyze the clinical features of respiratory epithelial adenomatoid hamartoma (REAH) in the nasal cavity. Methods: Clinical datas of 23 patients, who were hospitalized in Department of Otorhinolaryngology Head and Neck Surgery, the Affiliated Hospital of Qingdao University, from February 2016 to February 2018 with histopathologically proved REAH in the nasal cavity were reviewed. There were 18 males and 5 females, with the age range from 16 to 71 years old. The most common area, main symptoms, surgical methods and follow-up results were analyzed. Results: The most common area was olfactory cleft (21 cases), and the mainly symptom was nasal congestion (18 cases). All the patients received transnasal endoscopic surgery and had no recurrence during following-up from three months to one year. Conclusions The most common area of REAH in the nasal cavity is the olfactory cleft. Histopathological result is needed to make a definite diagnosis. Complete surgical resection is the main treatment.

Objective To evaluate the mid-and long-term results of chimney-endovascular aneurysm repair (Ch-EVAR) on efficacy and durability.Methods Data of abdominal aortic aneurysm (AAA) patients receiving Ch-EVAR were retrospectively collected and analyzed.Results From Jan 2011 to Dec 2016,21 patients received Ch-EVAR in our institution including 18 males and 3 females with the average age 74.0 ±6.31 years.One patient died and 20 patients were followed up for an mean period of 53.2 months.During EVAR procedures 14 patients received left renal artery chimney stents,6 patients had right renal artery chimney stents and one did bilateral renal artery chimney stents.Technical success was achieved in all patients (100％).Differences between preoperative and one-week postoperative value of serum creatinine (P =0.639) and estimated glomerular filtration rate (eGFR) (P =0.804) showed no statistical difference.The differences of maximum sac diameter between preoperiation (60.1 ± 13.1 mm) and follow-up (59.2 ± 13.5 mm) was not significant (P =0.826).Six patients died during follow-up and none was aortic events related.All chimney stents were patent.One patient developed late type Ⅱ endoleak and refused reintervention regardless of aneurysm expansion.Conclusion For short hostile neck AAA patients with considerable surgical risk Ch-EVAR may be an effective and durable alternative.

Objective: To analyze the epidemiological characteristics and its trends of other infectious diarrhea diseases in infants in Inner Mongolia Autonomous Region. Methods: Statistical analysis was conducted on other infectious diarrhea cases of infants in Inner Mongolia Autonomous Region from China Information System for Disease Prevention and Control from 2005 to 2016. The main methods were descriptive epidemiology for population, area and time distribution of these registered cases in Inner Mongolia Autonomous Region. The trends were analyzed by the ratio of fixed base and ring base. Area map method was used for regional differences. Results: From 2005 to 2016, 17 760 other infectious diarrhea diseases of infants were reported in Inner Mongolia Autonomous Region, accounting for 58% of the total reported cases. The cases number and incidence showed an overall upward trend. After 2011, the growth rate of case reports and incidences slowed down relatively. The peak of the incidence was in July and August (4 739 cases), accounting for 27% of cases of the whole year. Seventy-three point forty-four percent of the cases were located in Hulunbeier City (5 161 cases, 29.06%), Hohhot City (4 465 cases, 25.14%) and Baotou City (3 417 cases, 19.24%) . Except for Wuhai City, the remaining 11 cities showed increased incidence of other infectious diarrhea diseases in infants. The ratio of male to female was 1.55∶1, and the incidence in males was higher than that in females every year. Twelve-month-old (5 800 cases, 33%) had the greatest proportion. Clinical diagnosis (56.26%) and confirmed diagnosis (43.51%) were the main categories, but the rate of pathogen labeling was only 7.60%. Conclusions After 2011, the incidence of other infectious diarrhea diseases of infants in Inner Mongolia Autonomous Region have slowed down relatively. However, the incidence has significant time, region and population aggregation.

OBJECTIVETo study the effect of chrysin in inducing apoptosis of human hepatic carcinoma cells and explore the possible mechanism.

METHODSHuman hepatic carcinoma SMMC-7721 cells treated with DMSO or chrysin at different concentrations (5-200 μg/mL) were examined for changes in the cell proliferation using CCK-8 assay. The morphological changes of SMMC-7721 cells were observed in response to treatment with 5, 10, or 20 μg/mL chrysin, and the changes in the cell nuclei were observed using DAPI nuclear staining. Annexin Ⅴ-FITC/PI flow cytometry was used to determine the cell apoptosis rate. The changes in the apoptosis-related proteins (PARP and caspase-3) and MAPKs signal pathway were detected with Western blotting.

RESULTSChrysin treatment obviously suppressed the proliferation of SMMC-7721 cells in a dose-dependent manner below the concentration of 60 μg/mL. Chrysin (20 μg/mL) also caused significantly increased cell apoptosis and significant cleavage of PARP and caspase-3. Chrysin significantly activated MAPKs signaling pathway in a time-and dose-dependent manner, with the peak activation level occurring at 15 min. Pretreatment of the cells with specific inhibitors of the MAPKs pathway obviously inhibited the effect of chrysin in inducing cell apoptosis.

CONCLUSIONSChrysin inhibits the proliferation and promotes apoptosis of SMMC-7721 cells by regulating the activation of MAPKs signaling.

The traditional conotation of combination of disease and syndrome means the combination of disease differentiation in traditional Chinese medicine (TCM) diseases and TCM syndrome differentiation,which was derived from the Yellow Emperor's Inner Classic.And the Treatise on Cold Damage and Miscellaneous Diseases describes the clinical application of this theory.Under the background of integrative medicine,the modern conotation of combination of disease and syndrome means TCM syndrome differentiation and treatment based on modern medicine disease differentiation,which is commonly used in the current clinical practice.The disease and syndrome combination diagnosis mode based on syndrome,etiology,pathology and pharmacology can understand the disease from a multiple and comprehensive level,in order to realize the combination and complementation of advantages from both medicines.In addition,formula-syndrome relation means the relationship between the formula and its relevant indications.In general,indications often involve syndromes,symptoms,diseases and body constitutions.And the application of formula in the Treatise on Cold Damage and Miscellaneous Diseases is the representative of this theory.Hence,the application of associated classical formula gives example to the clinical formula-syndrome relation application in modem times.

OBJECTIVETo analyze early hematopoietic response and long-term survival of very severe aplastic anemia (VSAA) patients with different absolute neutrophil counts (ANC) after frontline immnunosuppressive therapy (IST).

METHODSClinical data and outcome of 145 VSAA patients treated with rabbit antithymocyte globulin combined with cyclosporine were retrospectively analyzed. Hematopoietic responses to IST and long-term survival were statistically analyzed for VSAA patients in different ANC subgroups.

RESULTSPre-IST ANC=0.05×10(9)/L acted as the best cutoff level to predict IST response at 3, 6 months. For 145 VSAA patients, early death rate was 13.4% (11/82) vs 1.6% (1/63), respectively, in the ANC≤0.05×10(9)/L group and ANC>0.05×10(9)/L group (P<0.05). Hematopoietic response rates to IST was 22.0% vs 54.0% (P=0.000) at 3 months, 34.1% vs 63.5% (P=0.000) at 6 months; the overall five-year survival rate was only (62.5±5.4) % vs (91.4±3.7) % (P=0.000) and five-year event-free survival rate was (42.3±5.5) % vs (63.1±6.5) % (P=0.003), respectively, in the ANC≤0.05×10(9)/L group and ANC>0.05×10(9)/L group.

CONCLUSIONVSAA patients with extremely low ANC (≤0.05×10(9)/L) had high early death rate and with very low response rate to frontline IST and poor survival, so it is urgent to seek for the alternative frontline therapy that will bring faster and better outcome for these patients.
