Thoracentesis is common in daily medical practice. During the operation, it is easy to cause complications such as re-expansion pulmonary edema, pulmonary hypotension, liver and spleen injury, pleural reaction, intercostal artery injury, pneumothorax, and so on. If the operator does not master procedures properly, it is easy to damage the thoracic organs. Therefore, the department of the general practice of the First Hospital of Jiaxing improved the puncture needle device based on thoracic puncture cannula, developed a new type of disposable thoracic puncture cannula, and obtained the National Utility Model Patent of China (patent number: ZL 2019 2 2112955.7). New type of disposable thoracic puncture cannula comprises a flexible puncture cannula, a steel needle, a limit structure, and a second bolt. In the process of puncture, the length of the puncture is limited by the limit structure. If the puncture force is too strong, the limit structure will prevent further penetration of the needle. The device is easy to use, flexible to operate, easy to master, and can reduce the risk of thoracentesis, which is worth of clinical promotion.

Objective:
To understand poor oral habits of preschool children and related factors, so as to provide evidence for child oral health promotion.
Methods:
A total of 3 094 preschool children from 12 kindergartens in Wuhan and Ezhou were selected by cluster sampling method. Basic demographic information and child poor oral habits were evaluated through questionnaire survey. Chi square test was used for univariate analysis and binary Logistic regression was performed for multivariate analysis.
Results:
About 33.5% of preschoolers were found to have poor oral habits. Among them, biting nails and toys (4.4%), sucking fingers ( 3.8% ), mouth breathing (3.7%) ranked the highest. Multivariate analysis showed that only child( OR =1.26), picky eaters( OR =1.30), and exposure to second hand smoke ( OR =1.69) were associated with poor oral habits, while living in cities( OR =0.58), high family economic status ( OR =0.66), and good health ( OR =0.37), balanced diet ( OR =0.71), maternal high school education ( OR =0.72) were associated with better oral habits( P <0.05).
Conclusion
Preschool children s oral habits are affected by variable factors, attention should be paid to children who are the only child of the family, picky eaters, living in rural areas, and those exposed to second hand smoke.

Objective To investigate the changes aad possible role of estrogen and its receptor ERα、ERβ、GPR30 in the pathogenesis of asymptomatic hyperuricemia.Methods The peripheral blood of 62 asymptomatic hyperuricemia patients (AH) and 68 healthy controls (HC) were collected.The expression of estradial (E2) in serum was detected by the chemilluminescent microparticle immunoassay (CMIA).The expression of ERα,ERβ,GPR30 mRNA in peripheral blood mononuclear cells (PBMCs) was measured using Real time quantitative polymerase chain reaction (RT-qPCR).Statistical Package form Soci-science (SPSS) 17.0 statistical software was used for data analysis.The measurement data were compared by t test,rank sum test or one factor analysis of variance test.The correlation between variables was used by Spearman correlation analysis.Results ① The expression of E2 in serum of the HC group was higher than that in the AH group [(38.7±10.2) pg/ml vs (33.7±8.6) pg/ml,Z=-0.356,P<0.05].② The expression of ERα,GPR30 mRNA in PBMCs of HC group was increased,compared with that in the AH group (0.000 17±0.000 23 vs 0.000 12± 0.000 12,0.002 0±0.002 1 vs 0.001 5±0.000 8,Z=-2.112,-2.147,P<0.05,respectively).No significant difference in PBMCs ERβ mRNA levels was found between HC group and AH group,while a slight but not significant increase was observed in HC group.③ The Spearman correlation analysis found that the expression of ERα and ERβ mRNA,E2 and GR,ERβ and GLU in the AH group were positively related (r=0.259,0.251,0.260,P<0.05,respectively).Conclusion The expression of E2,ERα,ERβ,GPR30 mRNA in the peripheral blood of patients with AH is decreased,suggesting that the estrogen and its receptor may be involved in the patho-genesis of hyperuricemia.

Objective To investigate the occurrence of maternal stress under the epidemic, and analyze its relevant factors, to provide a reference for improving pregnancy quality and psychological counseling services during pregnancy. Methods From April to July 2020, 293 pregnant women from maternity and childcare hospital in Wuhan and Huanggang were selected as the subjects of the cross-sectional survey. Results The average score of the PSS pressure scale for pregnant women was (17.75±6.07), among which no/mild, moderate and severe stress accounted for 22.8%, 63.1% and 14.1%, respectively. According to multiple linear regression analysis, the factors affecting the maternal stress level of pregnant women are poor psychological resilience (β=-0.206, 95% CI: -0.288~-0.124), low family income (β=-0.370, 95% CI: -0.729~-0.012), excessively fearful about their babies (β=1.775, 95% CI: 0.640~2.910) and themselves (β=1.695, 95% CI: 0.625~2.766) about infected with the new virus. Conclusion The present study explores the factors related to maternal stress and depression during the epidemic. For pregnant women with high psychological stress, it is recommended that medical staff and family members should take care of them in a timely manner, strengthen their social support, and provide psychological counseling positively in order to improve pregnant women's psychological mood and promote maternal and infant health.
