Objective To evaluate the necessity of concomitant bladder cuff and the possibility of distal ureter sparing surgery during radical nephroureterectomy of low-level upper urinary tract tumors. Methods Clinical data of 73 patients with low-level (Tis-T3 M0 N0 ) tumors of the proximal upper urinary transitional epithelial cancer treated in radical nephroureterectomy in our hospital from 2000 to 2007 were analyzed retrospectively. The medical charts and pathologic specimens of 35 patients with, and 38 patients without, concomitant bladder cuff were reviewed. Results In the 35 patients with concomitant bladder cuff resection, 8 cases (22.9%) recurrence was observed; in the 38 patients without concomitant bladder cuff resection, 8 cases (21.1%) recurrence was observed. There was no difference between both groups(P>0.05). In the 19 patients suffered renal pelvis tumors with concomitant bladder cuff resection, 4 cases (21.1%) recurrence was observed; In the 16 patients suffered ureter tumors with concomitant bladder cuff resection, 4 cases (25 %) recurrence was observed.There is no difference between patients of renal pelvis tumors and of ureter tumors with concomitant bladder cuff(P>0.05). In the 27 patients suffered renal pelvis tumors without concomitant bladder cuff resection, 3 cases (11.1 %) recurrence was observed; in the 11 patients suffered ureter tumors with concomitant bladder cuff, 5 cases (45.5%) recurrence was observed. There was significant different between patients of renal pelvis tumors and of ureter tumors without concomitant bladder cuff (P<0. 05). Conclusion Concomitant bladder cuff resection confers a favorable prognosis to the patients with ureter tumors, but not to the patients with renal pelvis tumors.

BACKGROUND:Titanium al oy with good biocompatibility, corrosion resistance and mechanical properties have been widely used in clinic. How to give its excel ent antibacterial properties so as to cope with plant-associated infections has become a research focus in recent years. OBJECTIVE:To review the principle, techniques, classification and relative merits of antimicrobial coating. METHODS:A computer-based search of Scopus database and VIP database was performed by the first author to retrieve relevant articles published from January 1990 to January 2014 using the keywords of“titanium al oy, plant, antibacterial, coating”. RESULTS AND CONCLUSION:Coatings can be classified into antibiotic coating, non-antibiotic organic antimicrobial coating, inorganic antibacterial coating, anti-adhesion coating, antibacterial bioactive polymer coating, al of which have better biocompatibility, but also have their limitations. Current studies concerning antimicrobial coatings mainly focus on how to enhance the binding force between antimicrobial coating and the substrate as wel as how to get a good anti-bacterial ability, biocompatibility, high wear resistance and persistence;antibacterial phase structure and distribution effects on the bacterial colonization. The antibacterial phase structure and distribution is the key factor for the antimicrobial properties of titanium al oys with either entirely added anti-bacterial elements or surface coating.

Objective To study the presence of microflammation state in ESRD patients and the relationship between microinflammation state and atherosclerosis. Methods Inflammatory cytokines and carotid artery B ultrasound data of 246 ESRD patients and 43 cases with normal renal function as control were collected. The presence of microflammation state and its relationship to atherosclerosis were studied. Results The levels of inflammatory cytokines(CRP,IL 6,TNF ?)in ESRD patients were mostly in normal range, but still much higher than those in control.According to the level of CRP,the patients were divided into three groups.Significant differences of carotid artery B ultrasound and prevalence of cerebrocardiovasculer events were found between two groups with CRP levels less and higher than 4 mg/L. According to the history of atherosclerosis cerebrocardiovasculer disease,patients were divided into two groups. Levels of CRP, IL 6, TNF ?were higher in patients with cerebrocardiovasculer disease than those in patients without, but still in normal range. Conclusions There is a microinflammation status in ESRD patients. The microinflammation status may be a risk factor of high prevalence and mortality of atherosclerosis related cardiovascular events in ESRD patients.

OBJECTIVETo evaluate the diagnostic value of salivary and plasma miR-21 in patients with esophageal cancer (EC).

METHODSTotal RNA was extracted from saliva and plasma samples from 50 stage I and 50 stage II patients with EC and 50 healthy controls for measurement of miR-21 levels using qPCR. The diagnostic values of salivary and plasma miR-21 levels were assessed for stage I, stage II, and stage I+II EC.

RESULTSSalivary and plasma miR-21 were significantly higher in the EC patients than in the control group. The diagnostic sensitivities of plasma miR-21 for stage I, stage II, and stage I+II EC were 96%, 64% and 97%, with specificities of 44%, 84%, and 56%, respectively; the sensitivities of salivary miR-21 were 90%, 88%, and 89%, respectively, with the same specificities of 64%. Regardless of EC staging, the expression of plasma miR-21 showed a significant positive correlation with that of salivary miR-21, and their diagnostic values were comparable.

CONCLUSIONBoth salivary and plasmatic miR-21 can be sensitive biomarkers for EC, and salivary miR-21 detection has the potential to replace plasma detection for EC diagnosis.

Objective: To investigate the feasibility and value of interphase fluorescence in situ hybridization (FISH) in the pathological diagnosis, differential diagnosis and therapeutic assessment of B-cell lymphomas. Methods: The cohort included 604 cases of B-cell lymphoma which were collected at West China Hospital from May 2010 to December 2016.And all were subjected to interphase FISH using 11 break apart or fusion probes (MYC, bcl-2, bcl-6, IRF4, MYC/IgH, bcl-2/IgH, CCND1/IgH, IgH, API2/MALT1, p53/ATM, and D13S319/CEP12). Results: The median age of the 604 B-cell lymphoma patients was 47.7 (aged 2-90) years including 372 men and 232 women. All the cases was divided into 463 large B cell lymphomas(LBL) and 141 small B cell lymphomas, and the total interphase FISH positive rate was 59.8% (361/604). Among the 463 LBL, 12.5% (58/463), 9.5% (44/463) and 2.2% (10/463) of cases showed MYC, bcl-6 and bcl-2 gene rearrangements respectively; and 363 diffuse large B cell lymphoma (DLBCLs) were reclassified as germinal center B-cell (GCB) subtype (38.6%, 140/363) and non-GCB subtype (61.4%, 223/363) by Hans algorithm. The rearrangement rates in GCB and non-GCB DLBCL were 45.7%(64/140)and 21.5%(48/223; P=0.001), respectively. Compared to the non-GCB DLBCL, GCB DLBCL showed higher MYC and bcl-2 gene rearrangements (P=0.001). Eleven (2.4%, 11/463) cases had MYC and bcl-6 or bcl-2 gene rearrangement (double-hit lymphoma); one (0.2%, 1/463) case had MYC, bcl-6 and bcl-2 gene rearrangements (triple-hit lymphoma); two (0.4%, 2/463) cases had bcl-2 and bcl-6 gene rearrangements. MYC translocation and MYC/IgH fusion were detected in 94.2%(81/86) and 83.7%(72/86) cases of Burkitt lymphomas. IRF4 rearrangement was detected in two cases of IRF4+ LBCL. Genetic abnormalities were detected in 9/19, 100%(29/29), 30.8%(12/39) and 68.5%(37/54) cases of follicular lymphoma, mantle cell lymphoma, MALT lymphoma and chronic lymphocytic leukemia, respectively. Conclusions Interphase FISH can rapidly and accurately detect the genetic changes in B-cell lymphomas. Different genetic changes are specifically valuable to the diagnosis, differential diagnosis, prognosis evaluation and treatment guidance of various B-cell lymphomas.

Toxoplasma gondii, an intracellular protozoan parasite that infects one-third of the world’s population, has been reported to hijack host cell apoptotic machinery and promote either an anti- or proapoptotic program depending on the parasite virulence and load and the host cell type. However, little is known about the regulation of human FHs 74 small intestinal epithelial cell viability in response to T. gondii infection. Here we show that T. gondii RH strain tachyzoite infection or ESP treatment of FHs 74 Int cells induced apoptosis, mitochondrial dysfunction and ER stress in host cells. Pretreatment with 4-PBA inhibited the expression or activation of key molecules involved in ER stress. In addition, both T. gondii and ESP challenge-induced mitochondrial dysfunction and cell death were dramatically suppressed in 4-PBA pretreated cells. Our study indicates that T. gondii infection induced ER stress in FHs 74 Int cells, which induced mitochondrial dysfunction followed by apoptosis. This may constitute a potential molecular mechanism responsible for the foodborne parasitic disease caused by T. gondii.

Staphylococcus epidermidis can exhibit both protective and opportunistic pathogenic effects on the skin: on the one hand, it suppresses pathogenic bacteria and inflammation, assists the innate immune system of the skin, and maintains homeostasis of skin microenvironment; on the other hand, it exhibits pathogenic potential. How Staphylococcus epidermidis affects human skin conditions depends not only on itself, but also on the communication among it, the host immune system, other microorganisms and environment factors. The balance of this interaction is the symbiotic homeostasis of Staphylococcus epidermidis, and when the homeostasis is disrupted, a variety of skin diseases such as acne vulgaris, atopic dermatitis, rosacea and melanoma can occur. Factors affecting the symbiotic homeostasis of Staphylococcus epidermidis include environmental conditions such as temperature, oxygen content and nutrition, antibiotics, the number of other microorganisms, microecological diversity, etc. This review summarizes recent research progress in symbiotic homeostasis of Staphylococcus epidermidis.

Objective:Analysis of influencing factors of enteral nutrition interruption in critically ill patients in general surgery department and its impact on prognosis.Methods:A total of 91 cases of critically ill patients in general surgery department were selected who were admitted to the general surgery of General Hospital of Eastern Theater Command of the Chinese People′s Liberation Army in Nanjing from June 2021 to March 2022 by convenient sampling method, demographic and enteral nutrition interruption data were collected,and patients were divided into enteral nutrition interruption group and enteral nutrition uninterrupted group to investigate the analysis of the factors of affecting enteral nutrition interruption and its impact on prognosis by Logistic regression analysis.Results:There were 59 cases in the enteral nutrition interruption group and 32 cases in the enteral nutrition uninterrupted group. There were statistically significant differences in gender, analgesic and sedatives, Gastro-kinetic agent and feeding intolerance between both groups ( χ2 values were 4.51-9.97, all P<0.05). Logistic regression analysis results showed that gender ( OR=4.566, 95%CI 1.332-15.657, P<0.05), analgesic and sedatives ( OR=3.437, 95%CI 1.112-10.621, P<0.05), and feeding intolerance ( OR=4.116, 95%CI 1.257-13.479, P<0.05) were the factors of enteral nutrition interruption. There were statistically significant differences between the two groups in the number of days of enteral nutrition up to goal in 3 days, 3-7 days and 7 days, albumin,length of stay in intensive care unit, total length of stay and hospitalization expenses between both groups ( Z values were -2.80 - -0.73, all P<0.05). Conclusions:Female, analgesic and sedatives and feeding intolerance are the risk factors of enteral nutrition interruption in critically ill patients in general surgery department, and enteral nutrition interruption has an adverse impact on the prognosis.Medical staff should avoid excessive use of analgesic and sedatives, and do well in feeding tolerance management to reduce the occurrence of enteral nutrition interruption.

Objective: To investigate craniofacial differences in individuals with hypodontia and explore the relationship between craniofacial features and the number of congenitally missing teeth. Methods: A cross-sectional study was conducted among 261 Chinese patients (males, 124; females, 137; age, 7–24 years), divided into four groups (without hypodontia: no teeth missing, mild: one or two missing teeth, moderate: three to five missing teeth, severe: six or more missing teeth) according to the number of congenitally missing teeth. Differences in cephalometric measurements among the groups were analyzed. Further, multivariate linear regression and smooth curve fitting were performed to evaluate the relationship between the number of congenitally missing teeth and the cephalometric measurements. Results: In patients with hypodontia, SNA, NA-AP, FH-NA, ANB, Wits, ANS-Me/N-Me, GoGn-SN, UL-EP, and LL-EP significantly decreased, while Pog-NB, AB-NP, N-ANS, and S-Go/N-Me significantly increased. In multivariate linear regression analysis, SNB, Pog-NB, and S-Go/N-Me were positively related to the number of congenitally missing teeth. In contrast, NA-AP, FH-NA, ANB, Wits, N-Me, ANS-Me, ANS-Me/N-Me, GoGn-SN, SGn-FH (Y-axis), UL-EP, and LL-EP were negatively related, with absolute values of regression coefficients ranging from 0.147 to 0.357. Further, NA-AP, Pog-NB, S-Go/N-Me, and GoGn-SN showed the same tendency in both sexes, whereas UL-EP and LL-EP were different. Conclusions Compared with controls, patients with hypodontia tend toward a Class III skeletal relationship, reduced lower anterior face height, flatter mandibular plane, and more retrusive lips. The number of congenitally missing teeth had a greater effect on certain characteristics of craniofacial morphology in males than in females.
