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.

Background Essential hypertension (EH) and type 2 diabetes mellitus (T2DM) are frequently co- existed.Previous studies proved that EH can cause arrythmia,whereas,the arrythmia and the structure changed in hypertensive patients coexisted with T2DM are scarely reported.Objective To study the characteristics and mech- anism of arrhythmia in essential hypertension (EH) patients with type 2 diabetes mellitus (T2DM).Methods One hundred sixty eight patients were groupped as follows:EH group (n=65),T2DM group (n=31),EH+T2DM group (n=52),and normal group (n=20).The clinical data,echocardiographies and 24-hour dynamic eletroear- diogram were determined in all patients.Results 1)Arrhythmia incidence in EH+T2DM group was a statistically higher compared to EH group and T2DM group(P

Objective To evaluate the role of large conductance calcium-activated potassium (BKCa) channels in vascular hyporesponsiveness in rats with obstructive jaundice.Methods Eighteen male Sprague-Dawley rats,weighing 180-200 g,were randomly divided into 3 groups (n =6 each) using a random number table:control group (group C),sham operation group (group S),and bile duct ligation group (group BDL).Obstructive jaundice was produced by common bile duct ligation.At 7 days after surgery,blood samples were collected for determination of the levels of serum total bilirubin (TBL),direct bilirubin (DBL),indirect bilirubin (IBL),alanine aminotransferase (ALT),and aspartate aminotransferase (AST).Thoracic aortic rings were prepared,and the endothelium was removed.The aortic rings were sequentially perfused with different concentrations of norepinephrine (NE) and sodium nitroprusside (SNP),and the maximum amplitude of contraction and dilatation of aortic rings was recorded.The aortic rings were then perfused with BKCa channel blocker Chtx with the final concentration of 10 7 mol/L,followed by perfusion with different concentrations of NE and SNP again,and the maximum amplitude of contraction and dilatation of aortic rings was recorded under each concentration.The percentage of maximum contraction and dilatation (maximum amplitude after Chtx administration÷maximum amplitude before Chtx administration× 100％) was calculated.Results Compared with C and S groups,the levels of TBL,DBL,IBL,ALT and AST in serum were significantly increased,the maximum amplitude of NE-induced contraction of aortic rings was decreased,and the percentage of the maximum NE-induced dilatation of aortic rings was increased,the maximum amplitude of SNP-induced contraction of aortic rings was increased,and the percentage of the maximum SNP-induced dilatation of aortic rings was decreased in group BDL.Conclusion Excessivc opening of BKCa channels may be involved in the mechanism of vascular hyporesponsiveness in rats with obstructive jaundice.

BACKGROUND: Heal-all oral biofilm is a material utilized in repairing oral mucosa and soft tissues defects and characterized by degradation, easily preparation, long preserved duration, convenient transportation and good ossification, which has been widely used in dental implant as guided bone regeneration materials.OBJECTIVE: To check the clinical effective of Heal-all oral biofllm on guided bone regeneration in dental implant.METHODS: A total of 72 patients with bone defects in the implantation area were selected as subjects, who were divided into control group and experimental group at random. Bone defects around implants were repaired by guided bone regeneration technique with BME-10X medical collagen membrane and Heal-all oral biofilm respectively. X-ray and clinical examination were taken at 1 and 3 months after implantation. The amount of new.formed bone tissue was evaluated when stage Ⅱ operation was performed.RESULTS AND CONCLUSION: In stage Ⅱ operation, osseointegration was formed between implants and bone tissue in all 72 patients. The average rate of bone formation was 92% in the experimental group while 91% in the control group. All implants were successfully repaired with implant denture. Occlusal function was restored successfully with all 72 implants during the follow-up period of 3-24 months after restoration. As an alternative option of BME-10X medical collagen membrane, Heal-all oral biofilm can be used in guided bone formation clinically.
