Objective: To study the relationship between primary tooth discoloration and caries in preschool children. Methods: 675 preschool children enrolled from 5 preschools in Suzhou City, China were examined for dental caries and tooth surface stain. Parents completed the questionnaires about their children's eating habit and living habit. The relationship between primary tooth discoloration and caries was analyzed with the respect to diet, hygiene, and the use of medicine or medical supplements. Results: Of the 675 children, 117(17. 3%; 52 boys and 65 girls) had tooth discoloration with no significant differences between gender(P> 0. 05). In the 117 children with tooth discoloration, 36(30. 8%) had dental caries, and in the 558 children without tooth discoloration 325 had caries (58. 2%, between the 2 groups, P< 0. 05). The incidence of discoloration was related with the frequency of consuming pigmented foods, vegetable and Chinese herbal medicines(P< 0. 05). The frequency of brushing teeth, use of water purifier and the water intake quantity were not significantly associated with discoloration of the teeth(P> 0. 05). Conclusion: The discoloration of primary teeth was negatively correlated with caries in primary teeth. Intake of pigmented food and medicine, vegetable and Chinese herbal medicine is related to tooth discoloration in preschool children.

Objective:
To report an investigation of a family cluster of coronavirus disease 2019 ( COVID-19 ) in Ningbo, so as to provide reference for the prevention and control measures.
Methods:
According to the COVID-19 Prevention and Control Program ( fourth version ) , an epidemiological investigation was conducted to collect the demographic information, clinical features and exposure history, to find the close contacts, and to figure out the source and route of infection.
Results:
Twelve confirmed cases and one asymptomatic case were reported. The attack rate was 16.05%. Among them, five were males and eight were females; the age ranged from 11 to 85 years old, with a median of 39 years old; most had mild symptoms. The incubation period was 2-13 days, with a median of 6.5 days. The first case ( Case 1 ) developed the symptoms on January 22, and had close contact with Zhang, an asymptomatic case, on January 20. Zhang was related to a cluster in the Buddhist assembly on January 19. Case 1, who caused the spread of the epidemic among family members, participated in several family visits and dinners from January 22 to 27 with other 24 families, resulting in six secondary cases and six third-generation cases. There were 54 close contacts except the family members, no infection was found.
Conclusion
This family cluster may result from the close contact with an asymptomatic case, and then spread within families through having dinners and living together.

BACKGROUND:
Textbook outcome (TO) can guide decision-making among patients and clinicians during preoperative patient selection and postoperative quality improvement. We explored the factors associated with achieving a TO for gallbladder carcinoma (GBC) after curative-intent resection and analyzed the effect of adjuvant chemotherapy (ACT) on TO and non-TO patients.
METHODS:
A total of 540 patients who underwent curative-intent resection for GBC at the Department of Hepatobiliary Surgery of the First Affiliated Hospital of Xi'an Jiaotong University from January 2011 to December 2020 were retrospectively analyzed. Multivariable logistic regression was used to investigate the factors associated with TO.
RESULTS:
Among 540 patients with GBC who underwent curative-intent resection, 223 patients (41.3%) achieved a TO. The incidence of TO ranged from 19.0% to 51.0% across the study period, with a slightly increasing trend over the study period. The multivariate analysis showed that non-TO was an independent risk factor for prognosis among GBC patients after resection ( P = 0.003). Age ≤60 years ( P = 0.016), total bilirubin (TBIL) level ≤34.1 μmol/L ( P <0.001), well-differentiated tumor ( P = 0.008), no liver involvement ( P <0.001), and T1-2 stage disease ( P = 0.006) were independently associated with achieving a TO for GBC after resection. Before and after propensity score matching (PSM), the overall survival outcomes of non-TO GBC patients who received ACT and those who did not were statistically significant; ACT improved the prognosis of patients in the non-TO group ( P <0.05).
CONCLUSION
Achieving a TO is associated with a better long-term prognosis among GBC patients after curative-intent resection, and ACT can improve the prognosis of those with non-TO.
