OBJECTIVETo discuss through retrospective study associated factors influencing orthodontists to develop orthodontic treatment plans and to calculate constituent ratio of a typical extraction in orthodontic treatment.

METHODSSystematic sampling was performed among 7 344 orthodontic patients, who received orthodontic treatment from April 2012 to March 2014 in the Department of Orthodontics, West China Hospital of Stomatology, Sichuan University. The study included statistical data on factors that may influence development of treatment plans. Samples were used to calculate extraction-ratio and atypical-extraction-ratio. Research focused on associated factors influencing development of treatment plans while evaluating correlation significances of each factor. Finally, treatment outcomes of atypical-extraction were compared with those of typical-extraction.

RESULTSAmong studied patients, 55.31% (406/734) received orthodontic extraction treatment. In orthodontic-extraction-treated patients, typical-extraction accounted for 59.11% (240/406), orthodontists-selected atypical-extraction accounted for 23.15% (94/406), and passive atypical-extraction accounted for 17.73% (72/406). With statistical analysis, we inferred associated factors influencing development of treatment plans as follows: sex and age of patients, sex of orthodontists, accurate condition of specific teeth, Angle's classification, and degree of midline deviation. Tooth loss before treatment also directly influences passive atypical-extraction. Statistically significant factors were not obtained. Significant difference of treatment outcome was not observed between atypical-extraction and typical-extraction-orthodontic treatment (P>0.05).

CONCLUSIONSAbove mentioned factors may influence orthodontists to develop treatment plans. However, orthodontists should also consider expected results of treatment strategies to prepare individual treatment plans on the basis of comprehensive analysis.

Objective To investigate the risk factors of abnormal circadian rhythm of blood pres-sure in patients with Stanford type B aortic dissection. Methods Case information of 204 patients with Stanford type B aortic dissection admitted to vascular surgery department of the Second Xiangya hospital of Central South University from January 2016 to December 2018 were retrospectively analyzed. According to patients'blood pressure rhythm during hospitalization, patients were divided into normal blood pressure cir-cadian rhythm group (127 cases) and abnormal blood pressure circadian rhythm group (77 cases). Demo-graphic information, ambulatory blood pressure monitoring results, comorbilities and medication treatment of the two groups were compared by using multivariate logistics regression analysis. Results The difference of the ambulatory blood pressure monitoring results{average night systolic blood pressure [(112. 90 ± 10. 00) mmHg vs (128. 15 ± 15. 20) mmHg], average night diastolic blood pressure [(66. 40 ± 7. 91) mmHg vs (76. 10 ± 7. 97) mmHg]}, comorbilities hyperlipidemia, renal failure, obstructive sleep apnea hypopnea syndrome, smoking and the medication treatment ( analgesics, hypnotics and intravenous antihypertensive medicine) were statistically significant (P<0. 05);multivariate logistic regression analysis showed that ob-structive sleep apnea hypopnea syndrome and renal failure were independent risk factors of abnormal blood pressure rhythm in Stanford type B aortic dissection patients. While analgesics, hypnotics and intravenous antihypertensive medicine were protective factors. Conclusions The risk factors of abnormal circadian rhythm of blood pressure in patients with Stanford type B aortic dissection are renal failure and obstructive sleep apnea hypopnea syndrome. Protective factors were the usage of analgesics, hypnotics and intravenous antihypertensive medicine.

mng·L-1 Xiaoban Tongmai Formula after inducing the abnormal proliferation of HA-VSMCs);enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of monocyte chemotactic protein-1(MCP-1),interleukin-6(IL-6),and interleukin-8(IL-8)in supernatant of the HA-VSMCs in various groups;real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of nuclear factor kappa-B(NF-κB)p65 mRNA and fibroblast growth factors 2(FGF2)mRNA in the HA-VSMCs in various groups;Western blotting method was used to detect the expression levels of NF-κB p65 and FGF2 proteins in the HA-VSMCs in various groups.Results:Xiaoban Tongmai Formula contained 103 active ingredients that exert anti-AS effect by acting on 189 target genes.The potential targets included IL-6,IL-8,vascular endothelial growth factor A(VEGFA),nuclear factor kappa B1(NF-κB1),and RELA(NF-κB p65).The GO functional analysis and KEGG pathway enrichment analysis results showed that Xiaoban Tongmai Formula exerted anti-AS effects by regulating lipid metabolism,hypoxia-inducible factor-1(HIF-1),epidermal growth factor(EGF),phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt),and NF-κB signaling pathways.The cell morphology and immunofluorescence staining results confirmed that the cells were HA-VSMCs.The oil red O staining results showed numerous red lipid droplets,indicating successful modeling.The MTT assay results showed that Xiaoban Tongmai Formula had no significant effect on the proliferation rate of HA-VSMCs within a certain dose range,indicating good safety.The ELISA results showed that compared with model group,the levels of MCP-1 and IL-6 in supernatant of the HA-VSMCs in rosuvastatin group and different doses of Xiaoban Tongmai Formula groups were decreased(P＜0.05 or P＜0.01),and the levels of IL-8 in supernatant of the HA-VSMCs in 0.050 and 0.100 mg·L-1 Xiaoban Tongmai Formula groups were decreased(P＜0.01);compared with rosuvastatin group,the levels of MCP-1 in supernatant of the HA-VSMCs in different doses of Xiaoban Tongmai Formula groups were decreased(P＜0.01),and the levels of IL-8 in supernatant of the HA-VSMCs in 0.050 and 0.100 mg·L-1 Xiaoban Tongmai Formula groups were decreased(P＜0.01).Compared with model group,the expression levels of NF-κB p65 mRNA in the HA-VSMCs in rosuvastatin group and different doses of Xiaoban Tongmai Formula groups were decreased(P＜0.01),and the expression levels of FGF2 mRNA in the HA-VSMCs in rosuvastatin group and 0.050 and 0.100 mg·L-1 Xiaoban Tongmai Formula groups were decreased(P＜0.01);compared with rosuvastatin group,the expression levels of NF-κB p65 and FGF2 mRNA in the HA-VSMCs in 0.050 and 0.100 mg·L-1 Xiaoban Tongmai Formula groups were decreased(P＜0.05 or P＜0.01).Compared with model group,the expression levels of NF-κB p65 and FGF2 proteins in the HA-VSMCs in rosuvastatin group and different doses of Xiaoban Tongmai Formula groups were decreased(P＜0.01);compared with rosuvastatin group,the expression levels of NF-κB p65 protein in the HA-VSMCs in 0.050 and 0.100 mg·L-1 Xiaoban Tongmai Formula groups were decreased(P＜0.01),and the expression level of FGF2 protein in the HA-VSMCs in 0.100 mg·L-1 Xiaoban Tongmai Formula group was decreased(P＜0.01).Conclusion:Xiaoban Tongmai Formula has anti-inflammatory effect,inhibitory effect on the proliferation of HA-VSMCs,and anti-AS effect,and its mechanism may be related to the inactivation of NF-κB/FGF2 pathway.
