Objective To investigate the carotid plaque conditions and clinical commonly used test events in patients with type 2 diabetes mellitus (T2DM) and to explore the risk factors affecting the stability of plaques in carotid artery.Methods According to the results of cervical vascular color Doppler ultrasound examination, 125 patients with type 2 diabetes mellitus were divided into unstable plaque group (n=21), stable plaque group (n =54), and non-plaque group (n =50).Analysis related results including age, gender, systolic blood pressure (SBP), diastolic blood pressure (DBP), intima-media thickness (IMT), fasting blood glucose (FBG), triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), uric acid (UA), fibrinogen (Fbg), D-dimer (D-D), free triiodothyronine (FT3), free thyroxine (FT4), and thyroid stimulating hormone (TSH) were analyzed.Results Age, gender, SBP, DBP, TG, HDL, D-D, and TSH were without significant differences among groups.Glucose and Fbg were significant different (P ＜ 0.05) between unstable plague group and stable plaque group/no plaque group.No significance difference was found between stable and no plaque groups.IMT, TC, LDL, and FT4 were significant different (P ＜ 0.05) between unstable and stable plaque groups, and between stable and no plaque groups.Logistic multiple regression analysis suggested that IMT and TC might be independent risk factors for the stability of plaques in carotid artery of patients with type 2 diabetes mellitus (P ＜ 0.05).Conclusions The factors affecting formation of plaques in carotid artery include glucose level, TC, and LDL in patients with type 2 diabetes mellitus.The factors affecting its stability include thickness of IMT, TC, LDL, and FT4.IMT and TC were the independent risk factors for the stability of plaques in carotid artery.

Objective To assess the disease severity and prognosis value by observing the kinetic change of serum procalcitonin(PCT)and PCT clearance rate(PCTc)in the patients with ventilator associated pneumonia (VAP). Methods A single-center prospective observational study was conducted. A total of 128 patients with VAP admitted into intensive care unit(ICU)of First Affiliated Hospital of Xinjiang Medical University from February 2012 to June 2014 were enrolled. The patients were divided into recovery group(n=88)and deterioration group(n=40) according to the therapeutic outcome. The acute physiology and chronic health evaluationⅡ(APACHEⅡ)scores were estimated within 24 hours when VAP was diagnosed. The serum PCT(PCT1,PCT5,PCT7,PCT9)and PCTc(PCTc5, PCTc7,PCTc9)were examined at 1,5,7 and 9 days after the VAP was diagnosed. The diagnostic and predictive performance of PCT,PCTc and APACHEⅡ scores were assessed by the receiver operating characteristic curve (ROC). Results APACHEⅡscores in recovery group were significantly lower than those in the deterioration group (14.49±5.30 vs. 18.90±5.30,t=-4.349,P=0.000). There was no significant difference in PCT level(μg/L)at 1 day after VAP was diagnosed between recovery group and deterioration group〔2.84(0.81,6.43)vs. 3.50(0.97,10.27), Z=-1.431,P=0.152〕. With prolonged treatment,PCT was gradually decreased in recovery group,while remained at higher level in deterioration group,which was significantly lowered at 5 days after VAP diagnosed in recovery group compared with that in the deterioration group〔1.28(0.65,3.13)vs. 2.39(0.78,9.35),Z=-2.012,P=0.044〕. PCTc maintained higher level in recovery group which was gradually increased with the improvement of the disease, and PCTc in deterioration group was lowered which was gradually decreased with the development of the disease. PCTc at 5,7,9 days in recovery group was significantly higher than that in deterioration group〔5 d:50.43(20.39,80.60)%vs. -56.68(-286.28,172.92)%, Z=-2.250, P=0.024;7 d:54.01(5.70,102.30)% vs. -76.91(-335.03, 181.21)%,Z=-2.561,P=0.010;9 d:63.88(25.93,101.80)%vs.-133.49(-547.20,280.16)%,Z=-3.133, P=0.002〕. The area under ROC curve(AUC)of PCT5,PCT7,PCT9 predicting the prognosis was 0.591,0.683, 0.746,respectively〔95% confidence interval(95%CI)was 0.456-0.726(P=0.161),0.557-0.808(P=0.005), 0.631-0.860(P=0.000)〕. When PCT9 was 5.65μg/L,the sensitivity of 95%and the specificity of 61%. The AUC of PCTc5,PCTc7 and PCTc9 was 0.648,0.685,0.729,respectively〔95%CI was 0.513-0.783(P=0.028),0.555-0.815(P=0.006),0.607-0.851(P=0.001)〕. When PCTc9 was 92%,the sensitivity was 98%and the specificity was 71%. The AUC of APACHEⅡscore was 0.693(95%CI 0.578-0.808,P=0.003). When APACHEⅡscore was 19.5,the sensitivity was 77%and the specificity was 58%. Conclusions The increased levels of PCT in patients with VAP were associated with the poor control of infection and may indicate the deterioration of VAP,it also can reflect the activity of lung infection in time. Keep observing the dynamic change of PCT and analyzing PCTc is more useful. The PCTc levels may provide evidence of disease progression and helpful in risk stratification in patients with VAP,and lower level of PCTc may accompany serious infection and predict poor prognosis.

Objective To explore the effect of a herbalcompound Gehua Jiejue Dizhi Decoction (GJDD) on the liver fat deposition and the expression of PXR, and the mRNA and protein expression of its target genes CYP3A11 and CYP3A25in the liver tissues of mouse models of alcoholic fatty liver.Methods Twenty-nine healthy male C57BL/6J mice were randomly divided into control group (n=5), model group (n=8), high dose GJDD group (n=8)and low dose GJDD group (n=8).The mouse model of alcoholic fatty liver was prepared according to the National Institute on Alcohol Abuse and Alcoholism (NIAAA) method.Then, the mice were treated with the high dose and low dose GJDD for 9 days.Serum glutamic-pyruvic transaminase (AST) and aspartate aminotransferase (AST) were detected by enzyme-linked immunosorbent assay (ELISA).Liver fat deposition was detected by oil red O staining.Real-time RT-PCR and immunohistochemistry were performed to examine the expressions of PXR, CYP3A11 and CYP3A25.Results Compared with the model group, the liver fat deposition in the intervention groups was significantly reduced in a dose-dependent manner, with a significant increase of the expression of PXR and CYP3A25 (P < 0.01).The serum ALT level was significantly reduced in the model group (P < 0.01), while the transcriptional levels of CYP3A11 mRNA in the groups were similar (P ≥ 0.05).Conclusions Gehua Jiejue Dizhi Decoction has obvious therapeutic effect on the AFLD in mice, which may be related to the activation of PXR and its target genes CYP3A25.

Objective To study the effect and prognosis of multiple channels percutaneous renal ureteral calculi removal in the treatment of patients with complex renal calculi.Methods One hundred and forty-four cases patients with complex renal calculi accepted treatment in Dongda Hospital of Shanxian County from June 2012 to March 2015 for research.According to the random number table method,the patients were divided into the observation group and the control group,72 cases in each group.The single channel type was used in the control group,while multi-channel type operation was use in the observation group.Indicators related to the operation,stones clearance rate,changes in the degree of hydronephrosis,and the major complications after treatment of the two groups were compared.Results The operation time of the observation group was (104.82 ±8.54) min,significantly longer than that of the control group ((90.23 ±7.68) min),but the duration of hospital stay,fistulation tube indwelling time and the residual stone surface area were (6.84±1.25) d,(5.23±2.16) d and (223.16± 113.49) mm2 respectively,significantly less than that of the control group ((8.33±2.13) d,(6.74 ± 2.19) d and (429.54 ± 107.88) mm2 respectively),the differences were statistically significant(P =0.000).The stone removal rate of the observation group was 86.11％ (62/72),significantly higher than that of the control group(72.22％ (52/72)),the difference was statistically significant (P =0.040).There was no significant difference in terms of the total stone clearance rate and the degree of kidney water after treatment between the two groups (P＞0.05).The total complication rate of the observation group was 11.11％(8/72),of the control group was 9.72％ (7/72),and the difference was not statistically significant(P ＞0.05).Conclusion The efficacy of multi-channel operation for complex renal calculi is better,safe and feasible,but should reduce the number of channels as much as possible,so as to reduce the damage to patients effectively.
