Objective To compare the diagnostic value of 64-slice helical CT cholangiography and MR cholangiopancreatography (MRCP) for pancreaticobiliary obstructive diseases. Methods Thirty-six patients with pathologically proved pancreaticobiliary obstruction or endoscopic retrograde cholangiopancreatography (ERCP) were examined with MRCP and routine enhanced CT scanning. CT row data of portal venous phase were reconstructed with 0.625 mm thickness and intervals. Then multiplanar reformation (MPR) of intra- and extrahepatic biliary duct, gallbladder and pancreas was generated, and curved planar reformation (CPR) was performed when necessary. The accuracy of MPR (and CPR) and MRCP in evaluating the site and nature of obstruction was compared. Results The accuracy of MPR and MRCP was 97.22% and 94.44% in evaluating the site of obstruction, respectively. In evaluating the nature of obstruction, the accuracy of MPR and MPCP was 83.33% and 80.56%, respectively, and the accuracy of MPR increased to 88.89% in combination with CPR in some patients. There was no statistical difference between the accuracy of MPR and MRCP in evaluating the site and nature of obstruction, while their diagnostic consistency was medium (Kappa=0.471). Conclusion Both MSCT cholangiography and MRCP have high diagnostic value in pancreaticobiliary obstruction, while the former gets some advantages in images review for clinicians.

A questionnaire was used to survey the perspective of the 22 mentors,24 students, 27 graduate students and 27 public health units on the competence of MPH student. The result showed that the practice skill,analyzing skill,program plan and practice skill,and emergency reaction abil-ity got more attention. This suggested that to the training of MPH,the training objective should focus on the ability to resolve problems; the curriculum should focus on the characters of public health and on the practice training.

The endophytic bacteria of the mangroves were studied in this paper. The results show that there are 1.728 (0. 195 -4.225)?104cfu/g (fw) bacterial endophytes in the variety of mangroves, the most population of the endophytic bacteria was found in Rhizophora stylosa, the figure was4. 225?104cfu/g (fw) , the next was Bruguiera gymnorrhiza, Aegiceras corniculatum, Kandelia candel and Avicennia marina. In parts of the mangroves, the contents of the bacteria in stem was the most, the figure was 1. 649?10 cfu/g (fw) , then the root and the leaf. Of the bacteria, about 43. 53% strains expressed the antagonism against the growth of the plant pathogens, such as Fusarium oxyspontm f. sp. cubense , Colletotrichum sp. and Rahtonia solanaceance etc. and these bacteria were identified as Bacillus sp. . The results also showed that 9 of the 13 strains (69. 23% ) could promote the growth of the tomato, while 4 strains (30. 77% ) restrained the tomato's growth.

Objective To evaluate the value of ultrasound in assessing superficial temporal arterymiddle cerebral artery(STA-MCA)anastomosis in patients with moyamoya disease.Methods Ultrasonic Doppler studies were made pre-and postoperatively in 25 patients with moyamoya disease undergoing STAMCA anastomosis.The peak systolic velocity(PSV),end diastolic velocity(EDV),pulsatility index(PI)and resistance index(RI)were measured in external carotidartery(ECA) and superficial temporal artery (STA)pre-and postoperatively.The pattern of the collateral circulation through the bypass was categorized based on postoperative external carotid angiograms.Thus three categories were determined as extensive,moderate and poor.The patients were divided into three groups based on the pattern of the collateral circulation through the bypass,which was determined based on the angiographic findings.PSV,EDV,PI,RI of STA was compared between groups.Results ①The values of the PSV,EDV of anastomosed STA were significantly higher and the values of PI,RI were significantly lower after operation.②The values of the PSV,EDV of the anastomosed ECA tended to be higher and the values of PI,RI tended to be lower in postoperation patients,but the differences were not significant within preoperation and postoperation group.③The Values of the PSV,EDV of the anastomosed STA were significantly different among the groups.The PSV.EDV tended to be higher and the PI,RI tended to be lower in patients with more extensive bypass flow.④The blood flow direction of STA was from extracranial to intracranial.Conclusions The PSV,EDV,PI,RI of STA can predicting the extent of collateral flow through an STA-MCA bypass.Color Doppler ultrasonography is a noninvasive method of assessing the function of STA-MCA bypass in patients with moyamoya disease.

more coincidence with ultrasound than SPECT. ConclusionsUltrasonography is a noninvasive method for assessing the effect of multiple burr-hole operation in patients with moyamoya disease.

OBJECTIVETo investigate the therapeutic effect of Yiqi Huaju Recipe (YHR) combined with routine therapy on the blood pressure, the blood pressure variability and other cardiovascular risk factors in hypertension patients complicated with metabolic syndrome (MetS).

METHODSTotally 43 hypertension patients complicated with MetS were recruited in this study and randomly assigned to the treatment group (22 cases, treated with basic routine treatment +YHR) and the control group (21 cases, treated with basic routine treatment + placebo). The treatment course was 12 weeks. Detected were parameters such as 24-h ambulatory blood pressure monitoring (ABPM), body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), homeostatic model assessment for insulin resistance (HOMA-IR), fasting glycosylated hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), 2 h postprandial plasma glucose (2 h PPG), fasting plasma insulin (FPI), serum lipid, etc.

RESULTSThe anthropometric parameters and plasma glucose levels (except HbAlc) were obviously lowered after treatment than before treatment in the treatment group (P < 0.01, P < 0.05). Besides, better effects were obtained in the WC, WHR, 2 h PPG, FPI and HOMA-IR (P < 0.05). The average blood pressure amplitude, the blood pressure variability, and blood pressure load at any time point were more obviously improved in the two groups after treatment than before treatment (P < 0.01, P < 0.05). Besides, partial indices were better in the treatment group than in the control group (P < 0.01, P < 0.05).

CONCLUSIONSYHR combined with routine therapy exhibited better effect on reducing the blood pressure amplitude, the blood pressure variability, and the blood pressure load in hypertension patients complicated with MetS. It could also effectively decrease the risk of other vascular disease.

This study aimed at evaluating the quality of the precise powder decoction pieces (PPDP) of L.japonicae Flos (LJF) compared with the traditional commercial slices with chemical fingerprint methods and DNA molecular identification technology.Different specifications of PPDP were prepared,their dry extract contents were in contrast with that of commercial slices.The three batches of commercial slices were collected,and the content uniformity,fingerprint and similarity evaluation before and after the mixing and pulverization were studied by HPLC-DAD and DNA sequence alignment.As a result,the paste rate of PPDP was slightly higher than that of the traditional commercial slices.The dissolution of chlorogenic acid of PPDP was higher than that of the traditional commercial slices.RSD of inter-assay dissolutions of chlorogenic acid of commercial slices was 11.93％,which was reduced to 8.29％ after mixing and preparing into PPDP.The fingerprint showed that the slimilarity of the fringerprint of the mixed and powdered LJF was elevated with 7 common peaks.All the common peaks were increased at different levels.In conclusion,compared with traditional commercial slices of LJF,PPDP apparently improved the dissolution rate and the quality uniformity,indicating that the boiled powder of CRP obviously presented vantages in clinic.
