Objective To compare the diagnostic accuracy of conventional urodynamic (CUD) and ambulatory urodynamic monitoring (AUM) in diagnosis of female stress urinary incontinence (SUI).Methods Forty women with SUI were prospectively enrolled and performed urodynamic studies after the ICI-Q-SF questionnaire.According to clinical symptoms,patients were divided into three groups:mild,moderate and severe group.Half patients in each groups performed CUD exam,and the other half of patients performed AUM exam.And two micturition cycles were recorded during AUM.Results There were no significant differrences in age,pregnant production times and ICI-Q-SF score between two groups.Three patients with SUI symptoms had negative findings in AUM group and 15 patients in CUD group (P＜0.05).Among women with SUI,1 1 patients had positive findings in AUM group and 2 patients in CUD group (P＜ 0.05).Conclusion AUM can provide objective evidence for the majority of patients with SUI than CUD.

To investigate the inherent characteristics of the pathogenic Yersinia enterocolitica. Polymerase chain reaction (PCR),analysis of DNA sequence,randomly amplified polymorphic DNA (RAPD) were used to study the pathogenic and nonpathogenic 10 strains of Yersinia enterocolitica. The Pathogenic Yersinia enterocolitica of serotyps 0∶3?0∶9 and 0∶5,27 were confirmed containing pathogenic gene of adherent invasion locus(ail) and their DNA fingerprints were much more similar,and it was also found that the serotype 0∶22 contained ail gene whose fingerprints was partly similar with the pathogenic ones in molecular structure. The pathogenic Yersinia enterocolitica strains were similar in the inherent and polymorphic. The serotype 0∶22 may have relativly evaluated association with pathogenic Yersinia enterocolitica, which is possible that it got potentially pathogenicity.

Though parched Chinese herbal medicines contain less effective or index components, their pharmacological actions do not reduce or even become improved to some extent. However, the current studies related to material basis could not explain the changes in property, flavour and efficacy of parched Chinese herbal medicines. Meanwhile, due to the lack of objective and specific evaluation indexes, the quality evaluation could not reflect features of parched Chinese herbal pieces. Therefore, how to break the bottleneck for the studies on parched Chinese herbal pieces, make further innovation and conduct in-depth studies on the material basis of parched Chinese herbal medicines are common problems that medical scholars are facing. According to the findings in the previous studies, the author proposed to explain the material basis of parched Chinese herbal medicines by studying Maillard reaction and establish specific quality evaluation indexes according to the features of parched Chinese herbal pieces, and conducted relevant studies.

Cytoplast and microprotoplast are main subprotoplasts that can play an important role in plant genetic improvement.The present review highlights the advancements in isolation and fusion of plant subprotoplast,and some suggestions and prospects are proposed for the future studies.

The role of methyl-CpG binding domain protein 2 (MBD2) in an ApoE-deficient mouse model of age-related macular degeneration (AMD) was investigated. Eight-week-old Mbd2/ApoE double deficient (Mbd2(-/-) ApoE(-/-)) mice (n=12, 24 eyes, experimental group) and MBD2 (wt) ApoE(-/-) mice (n=12, 24 eyes, control group) were fed on Western-type diet for 4 months. The mice were sacrificed, and total serum cholesterol levels were analyzed and Bruch's membrane (BM) of the eyes was removed for ultrastructural observation by transmission electron microscopy. Moreover, intercellular adhesion molecule 1 (ICAM-1) immunoreactivities were evaluated by fluorescence microscopy in sections of the eyes in both groups for further understanding the function mechanism of MBD2. There was no significant difference in the total serum cholesterol levels between control group and experimental group (P>0.05). Transmission electron microscopy revealed that AMD-like lesions, various vacuoles accumulated on BM, notable outer collagenous layer deposits and dilated basal infoldings of retinal pigment epithelium (RPE) were seen in both groups, and the BM in control group was significantly thickened as compared with experimental group (P<0.05). Fluorescence micrographs exhibited the expression of ICAM-1 in choroid was higher in control group than in experimental group. We are led to conclude that MBD2 gene knockout may lead to accumulation of more deposits on the BM and influence the pathogenesis of AMD via triggering endothelial activation and inflammatory response in choroid, improving microcirculation, and reducing lipid deposition so as to inhibit the development of AMD-like lesions. Our study helps to provide a new therapeutic approach for the clinical treatment of AMD.

OBJECTIVETo explore material bases and neurobiological mechanisms of "Shen storing will" by observing learning and memory capacities and N-methyl-D-aspartic acid (NMDA) receptor expressions in Shen deficiency constitution (SDC) rats.

METHODSTotally 40 SD rats were randomly divided into the model group, the Zuogui Pill (ZP) group, the Yougui Pill (YP) group, the blank control group (consisting of normal pregnant rats), 10 in each group. SDC young rat model (inherent deficiency and postnatal malnutrition) was prepared by the classic way of "cat scaring rat". Medication started when they were scared by cat. Rats in the ZP group and the YP group were administered by gastrogavage with ZP suspension 0.1875 g/mL and YP suspension 0.0938 g/mL respectively. Equal volume of normal saline was administered to rats in the blank control group and the model group by gastrogavage. All medication was given once per day, 5 days in a week for 2 consecutive months. Learning and memory capacities were detected by Morris water maze test. Expressions of NMDA receptor subunits NR2A and NR2B in hippocamus were detected by immunohistochemical method.

RESULTSCompared with the blank control group, the latency period, total distance in Morris water maze test were longer in the model group (P < 0.05). All the aforesaid indices all decreased in the ZP group and the YP group, with statistical difference when compared with the model group (P < 0.05). The protein expressions of NR2A and NR2B in hippocamus were lower in the model group than in the blank control group (P < 0.05). But when compared with the model group, they were obviously higher in the ZP group and the YP group (P < 0.05).

CONCLUSIONSSDC rats had degenerated learning and memory capacities and lowered NMDA receptor expressions. ZP and YP could up-regulate learning and memory capacities and NMDA receptor expressions, thereby improving deterioration of brain functions in SDC rats.

Objective To investigate the preventive effect of Indomethacin for post-ERCP pancreatitis and hyperamylasemia.Methods A total of 600 patients,who were undergoing ERCP,were randomly divided into 3 groups to receive anal Indomethacin (n=200),intravenous octreotide (n=200) or no special medication (n=200) before ERCP.The level of serum amylase before and 24h after ERCP were measured,and the rate of acute pancreatitis and hyperamylasemia after ERCP were assessed.Results Serum amylase levels before ERCP of all groups were normal.The mean serum amylase level of Indomethacin group (101.3±77.7 U/L) after ERCP was significantly lower than those of octreotide group ( 176.6±138.3 U/L,P =0.040 ]and control group (227.2±264.9 U/L,P=0.048),while there was no difference between octreotide group and control group ( P＞0.05 ).The incidence of post-ERCP pancreatitis in Indomethacin group (2.5％) was significantly lower than that of control group (9.5％,P=0.003),while there was no difference between octreotide group (4.5％) and control group ( P=0.05 ).The incidence of hyperamylasemia after ERCP in Indomethacin group (5.5％) was significantly lower than that of control group ( 13.5％,P=0.006 ),while there was no difference between octreotide group (10.0％) and control group ( P＞0.05 ).Conctusion Anal administration of Indomethacin before ERCP can effectively reduce the incidence of acute pancreatitis and hyperamylasemia after ERCP.
