Objective:To explore the diagnostic value of serum procalcitonin (PCT) level combined with Quantitative Computed Tomography (QCT) in elderly women with painful osteoporosis and its correlation with disease severity.Method:This study is a prospective study. From Jan. 2019 to Apr. 2020, 596 elderly women who underwent physical examination in our hospital were selected as the research subjects. All of them underwent dual-energy X-ray, PCT examination, and QCT examination serum. The diagnostic value of PCT and QCT in elderly women with painful osteoporosis was analyzed; Pearson correlation was used to analyze the correlation between the bone mineral density of lumbar vertebral 1, 2 vertebra, PCT and the severity of painful osteoporosis.Result:Among 596 elderly women, painful osteoporosis patients accounted for 50.84% (303/596) , bone mass reduction accounted for 21.98% (131/596) , and normal bone mass accounted for 27.18% (162/596) . Compared with the results of the diagnosis of painful osteoporosis by DAX, the diagnostic coincidence rates of PCT, QCT, QCT+PCT were 81.88% (488/596) , 93.62% (558/596) , and 97.31% (580/596) . QCT examination, QCT+PCT diagnosis coincidence rate is higher than PCT examination ( χ2=43.650, 83.187, P<0.05) ; QCT+PCT diagnosis coincidence rate is higher than QCT examination ( χ2=9.388, P=0.002) . The sensitivity, specificity, positive predictive value, and negative predictive value of QCT+PCT in the diagnosis of abnormal bone mass are higher than those of PCT ( P<0.05) ; the specificity and negative predictive value of QCT+PCT in diagnosing abnormal bone mass are higher than QCT Check ( P<0.05) . The bone density detected by QCT in the osteopenia group and the painful osteoporosis group was lower than that in the normal bone mass group, and the serum PCT level was higher than that in the normal bone mass group, the difference was statistically significant ( P<0.05) ; the painful osteoporosis group was in QCT detection of bone. The density was lower than that of the osteopenia group, and the serum PCT level was higher than that of the osteopenia group, the difference was statistically significant ( P<0.05) . The severity of painful osteoporosis was negatively correlated with bone mineral density detected by QCT ( r=-0.54, P<0.05) , and positively correlated with serum PCT ( r=0.59, P<0.05) . Conclusion:QCT vertebral bone mineral density determination combined with serum PCT detection has high accuracy, sensitivity, and specificity in the diagnosis of painful osteoporosis, and is closely related to the severity of painful osteoporosis, and can be used for clinical evaluation of the condition of painful osteoporosis patients.

OBJECTIVETo investigate the clinical effect of steroids on reducing postoperative edema in rhinoplasty.
METHODSCochrane, Medline data, Pubmed date, were searched and updated on October 2013. Randomized controlled trials(RCTS) studies were included to assess the efficacy of steroids on decreasing postoperative edema after rhinoplasty. The methodological quality of the included studies was evaluated, and date analyses were performed using the Cochrane Collaboration's software RevMan 5.2.
RESULTSA total of 4 RCTS involved 172 patients with rhinoplasty, including 87 patients in the experimental group( steroid) and 85 paitents in control group (placebo). Meta analysis results showed the edema in experimental group was significantly less than that in the control group on postoperative day 1 and 3 (P < 0.01), while the difference was not significant on postoperative day 7 (P = 0.19).
CONCLUSIONSPerioperative application of steroid in rhinoplasty can significantly reduce periorbital edema in the first postoperative day. The edema can completely be relieved after application of steroid for 3 days. It is a safe and effective way to reduce the postoperative edema.

Objective To study the effects of quantitative 24-hour urinary protein on the thyroid hormone levels in patients with severe preeclamp-sia,and clarify the impact of severe urinary protein on hypothyroid in severe preeclampsia patients. Methods A total of 166 patients with severe pre-eclampsia were recruited for the study and divided into mild proteinuria group(2.0-4.9 g/d),midrange group(5-10 g/d)and severe group(>10 g/d)according to the quantitative 24-hour urinary protein. 268 healthy female individuals with normal blood pressure and uric routine in the same stage of pregnancy and of the same age were selected into control group. Serum thyrotropin(TSH),free triiodothyronine(FT3)and free thyroxine (FT4)levels were determined by solid-phase chemiluminescent enzyme immunoassay method(CMIA). The thyroid peroxidase antibody(TPOAb) and thyroglobulin antibody(TGAb)concentration were detected by electrochemiluminescent assay(ECLIA). Results TSH levels were signifi-cantly higher in patients comparing to the control group(P<0.01). In addition,severe group showed higher TSH levels than mild group(P<0.01). FT4 and FT3 levels were obviously decreased with the progression of the disease(P<0.01 and P<0.05). The positive rate of TPOAb in mild group was significantly higher than that in moderate group(OR=9.8,P<0.05). There was no significant difference of the TGAb positive rate among three patient groups(P>0.05). The incidence of subclinical hypothyroidism and clinical hypothyroidism in severe group was significantly higher than that in mild group and in control group(OR=2.5,P<0.05 and OR=9.0,P<0.05;OR=8.0,P<0.01 and OR=43.4,P<0.01). Conclusion Our re-sults indicated that 24-hour urine protein in severe preeclampsia patients has extensive effects on thyroid hormones levels. With the increasing of quantitative 24-hour urinary protein,the level of TSH increased and the FT4 decreased. Thyroid autoantibody positiveness has extensive effects on 24- hour urine protein. Incidence of hypothyroid increased with the increase of quantitative 24-hour urinary protein. 24-hour urinary protein quantitative was a risk factor for hypothyroidism in severe preeclampsia patients. More attention should be paid to the monitoring of 24-hour urinary protein in se-vere preeclampsia patients.
