Objective To investigate the relationship between carotid atheromatous plaque and its related biochemical indexes and cerebral infarction.Methods 65 cases with cerebral infarction served as cerebral infarction(CI) group and 35 cases of non-cerebral infarction as control group. In both groups,the location,number and nature of carotid atheromatous plaque and diamete of carotid artery were assessed by Doppler ultrasonography,and the related biochemical indexes such as blood lipid,blood glucose and fibrinogen were evaluated.Results Significant differences of the detectable rate of carotid atheromatous plaque and the diameter of common carotid artery were found between CI group[81.54%,( 7.43? 0.07)mm of left side,(7.52?0.60)mm of right side] and control group[28.57%,(7.75?0.10)mm of left side,( 7.97? 0.75)mm of right side]( P

The article introduces the advances in the evaluation of transient ischemic stroke (TLA) and reviews them from four aspects, including identifying whether the symptoms accord with the diagnosis of TLA, which blood supply area the ischemia is located in, evaluating the pathogenesis of TIA, and predicting its prognosis.

Objective To compare the cardiac structure and function between diabetic and non-diabetic with different peritoneal transport type.Methods A total of 84 patients with continuous ambulatory peritoneal dialysis (CAPD) in our center for 6 months were enrolled in this study.Forty-six patients of subjects were diabetic,another 38 were non-diabetic.Patients were divided into four groups according to the results of peritoneal equilibration test (PET) and the ratio of creatinine concentration in dialysate solution and plasma (D/P creatinine concentration).Patients with D/P creatinine concentration ＞ 0.65 were with high permeability and otherwise were low permeability.The four groups were diabetic-H (high permeability) group,diabetic-L(low permeability) group,non-diabetic-H (high permeability) group,non-diabetic-L (low permeability) group.The levels of left atrial diameter (LAD),left ventricular diameter(LVD),interventricular septal thickness(IVST),left ventricular posterior wall thickness(LVPWT),left ventricular ejection fraction(LVEF) were measured before and after 6-month peritoneal dialysis by ultrasonic doppler.Results Before peritoneal dialysis,there were no significant difference in the terms of all parameters among four groups(P ＞0.05).After 6 months of peritoneal dialysis,the albumin levels,IVST,LVPWT and LVEF in diabetic-L group,non-diabetic-L,diabetic-H group and non-diabetic-H group were ((36.57 ± 3.34),(37.21 ± 4.12),(34.19 ± 3.98),(34.51 ± 4.52) g/L respectively;F =9.034),((10.45 ± 1.12),(10.17 ± 1.35),(11.32 ± 1.09),(11.46 ± 1.38) mm respectively;F =7.525),((9.58 ± 1.42),(9.47 ± 1.31),(10.71 ± 1.40),(10.15 ± 1.41) mm respectively; F =4.963) and ((63.98 ± 4.73) ％,(63.92 ± 5.17) ％,(60.12 ± 5.12) ％,(61.43 ± 5.57) ％respectively ;F =6.984),and the differences were statistic significant (P ＜ 0.05).Compared to diabetic-H group and non-diabetic-H group,there were significant difference in the terms of all above indexes between diabetic-L group,non-diabetic-L (P ＜ O.05).Conclusion The peritoneal transport.type of diabetic patients is high permeability,which might be an important factor affecting cardiac complications in patients.

Objective To investigate the effect of cystatin C (CysC) concentration on outcome of intravenous thrombolysis in patients with acute ischemic stroke.Methods The consecutive patients with acute ischemic stroke who underwent intravenous thrombolysis were enrolled retrospectively.They were divided into a good outcome group (≤2) and a poor outcome group (＞2) according to the Rankin scale.They were also divided into a hemorrhagic transformation (HT) group and a non-HT group according to whether they had HT or not.Their demographic data and clinical data were compared.Results A total of 103 patients with acute ischemic stroke treated with intravenous thrombolysis were enrolled,44 in the good outcome group,59 in the poor outcome group; 23 in the TH group,and 80 in the non-HT group.The age (62.34 ± 13.41 years vs.68.09 ± 9.74 years; t-2.521,P =0.013),baseline CysC concentration (1.008±0.28 mg/L vs.1.27±0.86 mg/L; t=2.237,P=0.027),incidence of HT (14％ vs.34.9％; x2 =6.016,P =0.014) and National Institutes of Health Stroke Scale (NIHSS) score (10.39 ± 3.11 vs.18 ±2.65; t =13.35,P ＜0.001) in the good outcome group were significantly lower than those in the poor outcome group.Multivariate logistic regression analysis showed that there was no significant independent correlation between CysC and clinical outcome (odds ratio 1.783,95％ confidence interval 0.443-7.185 ; P =0.416).The baseline CysC concentration (1.41 ± 0.54 mg/L vs.0.96± 0.18 mg/L; t =3.941,P=0.001) and the NIHSS score (15.96 ± 3.7 vs.13.05 ±4.87; t =3.017,P =0.004) in the non-HT group were significantly lower than those in the HT group.Multivariate logistic regression analysis showed that the plasma CysC concentration ＞ 1.03 mg/L (odds ratio 9.050,95％ confidence interval 2.384-34.359; P =0.001) was an independent risk factor for HT.Conclusions The increased baseline plasma CysC concentration was associated with the occurrence of HT in patients with acute ischemic stroke after intravenous thrombolysis therapy,but it was not associated with the outcomes.

Objective To investigate the value of clinical parameters in predicting the initiation of renal replacement therapy(RRT) in acute kidney injury (AKI) patients with cardiorenal syndrome (CRS).Methods A total of 75 AKI patients hospitalized with CRS were enrolled.All patients received pharmacologic therapy on the beginning 3 days.The patients whose heart function improved were divided into control group (n=39),and the patients whose heart function worsened were divided into RRT group (n=36).Clinical and laboratory data on the first day and the fourth day were collected and analyzed.The factors on the first day were labeled asⅠ ,and those on the fourth day were labeled asⅡ. The ratio of some parameters calculated were labeled asⅡ/Ⅰ .Area under curve (AUC) of receiver operating characteristic curve (ROC) of these factors was used to evaluate the sensitivity and specificity in predicting the initiation of RRT.Results The patients in RRT group had significantly higher levels of BNP-Ⅱ,BNP Ⅱ / Ⅰ and creatinine Ⅱ / Ⅰ (P ＜ 0.01),and lower levels of 24 hours urine volume-Ⅰ and 24 hours urine volume-Ⅱ (P ＜ 0.01).From ROC curve analysis,the AUC of 24 hours urine volume-Ⅰ,24 hours urine volume-Ⅱ,creatinine Ⅱ / Ⅰ,BNP-Ⅱ levels and BNP Ⅱ/Ⅰ to predict RRT were 0.736,0.875,0.747,0.779 and 0.894 respectively.When the cutoff values of 24 hours urine volume-Ⅰ,24 hours urine volume-Ⅱ,BNP-Ⅱ levels,BNP Ⅱ / Ⅰ and creatinine Ⅱ / Ⅰ were 905 ml (sensitivity 75％,specificity 94.9％),1450 ml (sensitivity 75％,specificity 100％),3360 ng/L (sensitivity 72.2％,specificity 100％),1.37 (sensitivity 75％,specificity 100％) and 1.25 (sensitivity 72.2％,specificity 94.4％) respectively,the value of the parameters to predict RRT was high.Conclusions The 24 hours urine volume,BNP levels after treatment and the dynamic changes of BNP levels and creatinine levels can be used as predictors of the initiation of RRT in the AKI patients with CRS.

Objective:To investigate the expression and clinical significance of PD-L1 in colorectal cancer (CRC). Methods:A total of 210 CRC patients who accepted radical surgery in our hospital from January 2015 to January 2016 were divided into three groups, namely, high-frequency microsatellite instability (MSI-H), low-frequency microsatellite instability (MSI-L), and microsatellite stable (MSS). The expression of PD-L1 was detected by immunohistochemistry, and the expression characteristics of PD-L1 in different types of CRC were analyzed. Results:CRC cases with low differentiation had a higher expression of PD-L1 than CRC patients with high differ-entiation (P<0.05). PD-L1 had a positive rate of 75.8%in the MSI-H group and a rate of 9.3%in the MSI-L and MSS groups, wherein the difference between the two groups was statistically significant (P<0.05). Conclusion:PD-L1 was positively expressed in some CRC tu-mor tissues, and its positive rate was significantly higher in MSI-H than in MSI-L and MSS. The therapeutic effect of a PD-L1 blocker for patients with MSI-H CRC might be preferable.

Objective To compare the effects of different administration routes and dosages of tropisetron on cisplatin-induced kaolin intake in rats.Methods Ninety-six healthy adult male Wistar SPF rats were randomly divided into 8 groups(n =12 each):intrathecal (IT) control group (group TC) and 3 tropisetron groups receiving IT tropisetron 10,20 and 30 μg,the volume of each group was 30 μl (group T10,T20,T30),intravenous(Ⅳ) control group (group IC) and 3 tropisetron groups receiving Ⅳ tropisetron 0.3,0.5 and 0.7 mg/kg respectively (group I0.3,I0.5,I0.7).In group TC and IC,normal saline 30 μl and 0.5 ml were injected IT and Ⅳ,respectively.All rats received cisplatin 3mg/kg by intraperitoneal injection at the time point of thirty minutes after administration,each rat weight,the daily food and kaolin intakes were detected at the time point of 48 hours after cisplatin administration.Results Compared with group Tc,each rat weight loss,the kaolin intakes were significantly decreased (P ＜ 0.05),and food intake dose was significantly increased in group T20 (P ＜ 0.05).Compared with group IC,each rat weight loss,the kaolin intakes were significantly decreased (P ＜ 0.05),and food intake dose was significantly increased in group I0.5 and I0.7 (P ＜0.05).There was no significant difference between group I0.5,I0.7 and group T20.Conclusions The kaolin intakes and the rat weight loss can be decreased by IT tropisetron,and the food take dose was increased meanwhile,and IT tropisetron 20 μg has equivalent efficacy to IV tropisetron 0.5 or 0.7 mg/kg.IT could be the new administration route of tropisetron.

Objective To retrospectively explore the incidence and causes of apnea after operation for retinopathy of prematurity(ROP). Methods The clinical data of 17 premature infants with operation for ROP(ROP group)and the other 23 premature infants without ROP(control group)were collected.The occurrence of apnea(time of onset and remission and original diseases) was recorded after operation in ROP group and at adjusted 37 weeks of gestational age in control group.Follow-up was conducted for 4 weeks,and the prevalences of apnea were compared between these two groups.Results There was significant difference in prevalenees of apnea between ROP group and control group ( 52.9%vs 21.7%,P<0.05).In ROP group,time of occurrence of apnea was (38±40)h after operation,and time of remission was (126±145)h after onset.Among the infants with apnea,there were 3 cases of pneumonia(33.3%),1 case of hypoglycemia(11.1%)and 5 cases with unexplained causes(55.5%). Conclusion Infants after operation for ROP are more prone to apnea,and pediatricians and ophthalmologists are required to collaborate in the perioperative care.

The pathogenesis of HBsAg (+)/HBsAb (+) double positive hepatitis B virus infection was investigated by simulating HBsAg/HBsAb coexistence in vitro and establishing HBsAg/HBsAb double positive model in vivo. Eukaryotic expression plasmids PCI-SY, PCI-adw, PCI-adr, PCI-ayw, which expressed S gene product of different serotypes, were constructed and transfected into HepG2 cells. Recombinant proteins were purified from the transfected cells. At the same time, HBsAg mouse antiserum was obtained by immunizing mice with PCI-SY plasmid. HBsAg/HBsAb coexistence was simulated using these antigens and antiserum. Furthermore, the expression plasmids expressing different serotypes of S gene product including PCI-adw, PCI-adr, and PCI-ayw were injected into mice via tail vein. HBsAg and HBsAb in mice sera were tested at the first and 7th day respectively after antigen plasmids injection. Both in vitro simulation and in vivo animal models demonstrated that HBsAg antigen and HBsAb of the same serotypes could not coexist, but HBsAg antigen and HBsAb of different serotype could coexist. HBsAg/HBsAb double positive hepatitis B virus infection could be due to infection of viruses of different serotypes.
