OBJECTIVETo explore the incidence, degree, and pattern of rib cartilage calcification in congenital microtia patients, in order to provide reference for harvesting the rib cartilage, sculpturing cartilage framework.
METHODSFrom Jun. 2013 to Nov. 2014, 383 patients (age range, 6-45 years) underwent CT scans of the chest. 11 patients with bony diseases or traumatic history were excluded. The remaining 372 patients were divided by age into four groups as 6-15, 16-25, 26-35, 36-45 years old. Twenty patients (10 male and 10 female) were selected by the order of patient identification number in each age group, thus selecting a total of 80 patients (40 male and 40 female). Retrospective study of CT scans of the chest in 80 patients and the incidence, degree, and pattern of cartilage calcification of the sixth to eighth ribs were noted. A chi-square test is conducted to test whether there are significant difference between the variables through the SPSS 19.0 software.
RESULTSOverall, 40.4% (194/480) cartilage was calcified; female patients (47.50%, 114/240) showed higher frequency of calcification than male patients (33.33%, 80/240, P = 0. 025). Calcification rates of all age groups are 1.7% (2/120), 46.7% (56/ 120), 49.2% (59/120), 64.2% (77/120). Calcification rate of 6-15 years group is lowest in all groups (P < 0.05) while other three groups have no statistical significance (P > 0.05). Calcification rates of the sixth and sevent rib cartilage were higher than those of the eighth rib cartilage in all age groups except 6-15 years group, who had a similar rate of all three ribs. Calcification rate of all three rib cartilage was significantly increased with age. Calcification rates of the amle's rib cartilage and the female's in all age groups are 3.3% (2/60) and 0.0% (0/60) (6-15 years): 33.3% (20/60) and 60.0% (36/60) (16-25 years): 40.0% (24/60) and 58.3% (35/60) (26-35 years), 56.7% (34/60) and 71.2% (43/60) (36-45 years). In 6-15 years group calcification rates of male and female had a similar rate, while female's rates were higher than male's rates in other three groups. Male and females mainly had the granular type of calcification [70.0% (56/80), 63.2% (72/114)].
CONCLUSIONSFemales who are over 16 years old should pay more attention to the possibility of middle-severe calcification before harvesting rib cartilage. These patients should take CT examination if necessary. In addition, the patients who had previous operation, or traumatic history, rib deformity, or spine deformity should select the CT examination.

Objective:To investigate the effect of regional cerebral oxygen saturation (rSO 2) combined with neurophysiological blood pressure monitoring on brain protection and myocardial protection during carotid endarterectomy (CEA) in patients with carotid stenosis and coronary heart disease. Methods:One hundred patients with carotid artery stenosis complicated with coronary heart disease treated in Jinhua Central Hospital from June 2021 to June 2022 were randomly divided into control group and experimental group. All patients were scheduled to undergo CEA. Fifty patients in the control group were administered with empirically increasing basic blood pressure by 20% - 30%, and 50 patients in the experimental group were administered with blood pressure under the guidance of rSO 2 combined with motor evoked potentials (MEPs) and somatosensory evoked potentials (EPS). The neurological function indexes of the two groups [neuron specific enolase (NSE), central nerve specific protein (S100-β)], myocardial function indicators [cardiac troponin I (cTnI), B-type natriuretic peptide (BNP)], clinical indicators (eye opening time, extubation time, recovery room stay time, hospital stay) and the incidence of postoperative complications [delirium (POD), cognitive dysfunction (POCD), neurological impairment] were compard between the two groups. Results:Two sets of postoperative NSE and S100-β both increased ( P<0.05), but NSE and S100 in the experimental group after surgery were lower than those in the control group: (0.82 ± 0.14) μg/L vs. (1.18 ± 0.28) μg/L, (290.13 ± 27.25) mg/L vs. (301.98 ± 28.56) mg/L, the differences were statistically significant ( P<0.05). After surgery, cTnI and BNP increased in both groups ( P<0.05), but the cTnI and BNP in the experimental group were lower than those in the control group: (2.87 ± 0.74)] μg/L vs. (3.36 ± 0.83) μg/L, (3.01 ± 0.85) μg/L vs. (3.89 ± 0.92) μg/L, the differences were statistically significant ( P<0.05). The opening time, extubation time, recovery room stay time, and hospitalization time in the experimental group were shorter than those in the control group: (16.79 ± 3.15) min vs. (20.55 ± 3.83) min, (29.38 ± 4.66) min vs. (40.14 ± 4.57) min, (66.82 ± 15.80) min vs. (89.35 ± 24.78) min, (11.24 ± 4.89) d vs. (14.56 ± 6.74) d, there were statistical differences ( P<0.05). The incidence of postoperative complications in the experimental group was lower than that in the control group: 12.00% (6/50) vs. 28.00% (14/50), there was statistical difference ( P<0.05). Conclusions:The application of rSO 2 combined with neurophysiological blood pressure monitoring in CEA of patients with carotid artery stenosis and coronary heart disease has a good effect, which has brain protection and myocardial protection, can shorten the recovery time of anesthesia and hospitalization time, and reduce the incidence of postoperative complications.
