Objective To evaluate the effect of oral health instructions in nursing of marsupialized jaw cysts. Methods 46 patients with cysts of jaw were divided randomly into two groups (education group and control), 23 in each. In addition of normal nursing processes in both groups, patients in education group were offered more oral health instructions, such as pathogenesis of jaw cysts, mechanism of marsupialization, wear and clean of a cyst plug, and oral hygiene maintenance. 12 months later, compliance, satisfaction, treatment effect and oral hygiene condition of the patients in the two groups were studied and compared. Results 100%of patients in the education group could return to clinical visits on time and 96%of patients did cyst rinsing after every meal, which were significantly higher (χ2=6.9, P<0.05) than in the control (74% and 70% respectively). Patients′satisfaction in the two groups were also significantly different (χ2=9.109,P<0.05). Patients in the education group were much more satisfied with the treatment procedures than control. The treatment effect of the cyst in the education group [good (83%), moderate (17%), not so good (0%)] was significantly (χ2=7.793, P<0.05) better than control (good (43%), moderate (52%), not so good (5%)]. The secondary infection rates in the two groups were similar (χ2=1.022, P>0.05). Oral hygiene condition of patients in the education group was better than control in Debris Index (χ2=9.576, P < 0.05) and Plaque Index (χ2=8.212, P < 0.05). Conclusions Oral health instructions played positive role in improving patients′ compliance, degree of satisfaction, treatment effect and oral hygiene condition in patients with jaw cysts.

Abstract: Objective To investigate the preventive and therapeutic effects of anti-idiotypic monoclonal antibodies (Ab2β) of lactadherin on neonatal mice infected with human rotavirus (HRV), and to analyze the underlying mechanism. Methods Hybridoma technology was used to prepare Ab2β of lactadherin. One hundred and twenty 7-day-old Kunming mice were randomly divided into groups A, B, C and control, each consisting of 30 mice. Groups A, B, and C were all infected with HRV via oral gavage. Group A received no treatment, group B was orally administered lactadherin for 7 days prior to infection, and group C was orally administered lactadherin for 7 days after infection, the control group was orally administered cell culture medium that did not contain the virus. The clinical manifestations (diarrhea, body weight) at different time points after infection of the neonatal mice in each group were observed, and the content of rotavirus antigen in the feces of neonatal mice was detected by enzyme-linked immunosorbent assay (ELISA). After HRV infection for 7 days, immunohistochemical staining was used to examine the expression level of intercellular adhesion molecule-1 (ICAM-1) in mouse small intestinal tissues in each group. Results No diarrhea occurred in the control group at any time point. Groups A, B, and C showed diarrhea symptoms after HRV challenge for 1 day. The degree of diarrhea in groups B and C was lower than that in group A at 2-4 days after HRV challenge, and the difference was statistically significant (P<0.05). The HRV antigen content in the feces of the neonatal mice in groups B and C was lower than that in group A at 1-5 days after HRV challenge, and the difference was statistically significant (P<0.05). There was no significant difference in the degree of diarrhea and HRV antigen content between groups B and C at each time point (P>0.05). There was no significant difference in the body weight of the neonatal mice in each group before infection and 1 day after infection (P>0.05); the weight of neonatal mice in groups B and C was higher than that in group A at 3, 5 and 7 days after HRV challenge, and the difference was statistically significant (P<0.05), and there was no significant difference in body weight between groups B and C at each time point after HRV challenge (P>0.05). The number of ICAM-1 expressing cells in the small intestine of the three groups A, B, and C was higher than that of the control group after HRV challenge for 7 days, and the difference was statistically significant (P<0.05). The cell number and gray value of ICAM-1 expressing cells in groups B and C were lower than those in group A, and the difference was statistically significant (P<0.05). Conclusions Anti-idiotypic monoclonal antibodies (Ab2β) of lactadherin has a good preventive and therapeutic effects on human rotavirus infection in neonatal mice, and can significantly improve diarrhea symptoms and reduce HRV viral load. Its specific mechanism may be related to the inhibition of ICAM-1.

Objecive To investigate the prevalence of NDM-type carbapenemases in the carbapenem-resistant Escherichia coli strains collected from Ruijin Hospital, Shanghai Jiaotong University School of Medicine. The epidemiological characteristics of NDM-type carbapenemase-producing isolates were analyzed.Methods Eighteen strains were collected from November 2013 to January 2015 in the clinical microbiology laboratory of Ruijin Hospital. All of them were resistant to imipenem or meropenem (inhibition zone diameter≤19 mm). The blaNDM gene was detected by PCR. The amplified products were subjected to sequencing analysis. Conjugation experiment was carried out to verify the transferability of plasmids. Multilocus sequence typing (MLST) and pulsed field gel electrophoresis (PFGE) were performed to analyze the molecular epidemiology.Results The blaNDM gene was identified in 6 strains, 4 of which had blaNDM-1-type and 2 had blaNDM-5-type carbapenemase gene. Three strains were positive in the conjugation experiment. MLST analysis showed that 6 NDM carbapenemase-producing isolates belonged to ifve sequence types, corresponding to five PFGE-DNA patterns (A-E). Two of these isolates shared the identical sequence type (ST5018) and nearly the same PFGE-DNA patterns (A1, A2).Conclusions NDM-type carbapenemase-producing E. coli is identified in this study. Most blaNDM-positive cases were sporadic. Plasmid might play an important role in the spread of blaNDM inE. coli. The blaNDM-5 type carbapenemase gene was first identified in Shanghai, to which more attention should be paid.

Background and purpose:The lymph node metastatic model of rectal tumor is a useful tool for the research on tumor occurrence, development, metastasis and antineoplastic therapy. There are few reports about establishment of larger animal model. This study aimed to establish feasible and reproducible lymph node metastatic models of VX2 tumor in rabbits.Methods:The VX2 tumor tissue was put into the puncture needle. The VX2 tumor tissue in the needle was orthotopically transplanted into the rectal wall of the New Zealand white rabbits successfully. Twenty New Zealand white rabbits were transplanted. Two experimental rabbits were scanned by MR weekly. Tumor growth curve and lymph node numbers were observed on MR. Experimental rabbit tumor volumes were measured by MR post-processing software. The rectal tumor and surrounding lymph nodes were resected, and the specimens were ifxed. The sections were stained with HE. We explored the relationship between tumor volume and growth time, the number of metastatic lymph nodes and tumor volume, respectively.Results:Thirteen models were successfully established with a rate of 65%. Tumors limited in the rectal wall were observed on the fourth week. Tumor size increased over time. There was significant difference in the tumor volume between different periods (growth cycle number) (F=52.865,P<0.05). There was a signiifcantly positive correlation between tumor volume and the growth cycle number (r=0.910,P<0.05). The metastatic lymph nodes could be observed when VT>9 cm3. The number of metastatic lymph node increased obviously from the ninth week. The more tumor volume, the greater the number of metastatic lymph nodes was observed (F=92.531,P<0.05). There was a signiifcantly positive correlation between the number of metastatic lymph nodes and the tumor volume (r=0.945,P<0.05).Conclusion:Metastatic lymph node models of VX2 tumor in New Zealand white rabbits were established successfully. This model has some value in the research on local growth, invasion mechanism, lymph node metastasis and biological characteristics of rectal cancer.

Objective Three-dimensional(3D) automated ultrasonic volume measurement is becoming favorable in clinical application and turns to be an important direction .The article was to evaluate the consistency of two-dimensional (2D) and three-di-mensional ultrasonography in the diameter measurement of single follicle . Methods 438 single folliculars were respectively meas-ured by the same sonographer in 2D and 3D ultrasonic measurement.2D diameter, 3D mean diameter and 3D virtual ball diameter of every single follicle were recorded , and Bland-Altman method were used to evaluate the consistency of the results by these two meth-ods. Results In the consistency analysis on the diameter measurement of single follicle by 2D and 3D mean diameter measurment methods, d equaled -1.06 mm, and 95% LoA range covered the range of -4.82 mm to 2.70 mm.95% CI of 95% LoA range,-5.21 mm to 3.08 mm, was beyond the settings of clinical acceptable error limit range , -3.56 mm to 1.44 mm, showing poor consis-tency.Likewise, in the research of the consistency in the measurement of 2D diameter and 3D virtual ball diameter in the diameter measurement of single follicle , d equaled -0.07 mm , and 95%LoA range covered the range of -3.11 mm to 2.98 mm.95%CI of 95%LoA range, -3.43 mm to 3.29 mm, was beyond the settings of clinical acceptable error limit range , -2.57 mm to 2.43 mm, showing poor consistency . Conclusion 2D and 3D ultrasound measurements in the diameter measurement of single follicle are not consistent.However, considering the objectivity and accuracy of the results , 3D ultrasonography still has an advantage over 2D ultra-sonography , which can provide more acurate aid for assisted reproductive technology .

objective To assess the effect of aldosterone on the production of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9)and collagen Ⅳ in culture supematants of podocytes and the possible molecular mechanisms involved in the influence of aldosterone on the synthesis and degradation of extracellular matrix produced by podocytes. Methods Podecytes were treated with aldosterone at the concentration of 10-11, 10-9, 10-7 mol/L respectively. Cultured podocytes were examined at 24, 48 and 72 hours respectively. Spironolactone, a receptor antagonist of aldosterone, was added to observe the blocking effect on aldosterone. An inhibitor of TGF-β1 receptor was used to determine whether the effect of aldosterone on podocytes were mediated through TGF-β1 system. The enzymatic activities of MMP-2 and MMP-9 were assayed by gehtin zymography. Collagen Ⅳ 0.5 chain and TGF-β1 proteins released into culture supematants were assessed by Western blot and ELISA analysis. The adhesion rate of podocytes was monitored by flow cytometry. Results Aldosterone increased the activities of MMP-2 and MMP-9 in a dose- and time-dependent manner (P<0.05). Aldosterone decreased the level of collagen Ⅳ or5 chain protein in culture supernatants (P<0.05). Meanwhile, the expression of TGF-β1 was also increased (P<0.05). Spironolactone completely abolished the above-mentioned changes(P< 0.05). Blockage of TGF-β1 signaling with SB431542 prevented the aldosterone-induced upregulation of MMP-2 and MMP-9 as well as the downregulation of the collagen Ⅳ α5 chain protein and the adhesion rate of podocytes (P<0.05). Conclusions Aldosterone increases the activities of MMP-2 and MMP-9 but decreases the expression of collagen Ⅳ α5 chain and the adhension rate of podocytes possibly via TGF-β1 signaling pathway. Such alterations may contribute to glomerular podocyte injury associated with the GBM abnormality caused by the imbalance between matrix synthesis and degradation.
