ABSTRACT
Objective To compare the impact of bowel preparation on postoperative complications of patients undergoing radical cystectomy(RC) with ileal conduit diversion(ICD) by meta-analysis.Methods All literature were collected from VIP,CNKI,WanFang Data,CBMdisc,Pubmed,Medline,Embase dated from inception to April 2016.Then literature were grouped into mechanical bowel preparation and nonmechanical bowel preparation,whose differences in the wound,intestinal function,infection and other complications were compared.Results Three RCTs,four cohort studies and 656 cases were taken into account.No statistical difference was observed in the wound infection,wound dehiscence,fascia dehiscence,intestinal obstruction,anastomosis fistula,intestinal fistula,urinary leakage,death of indicators between the two groups.Conclusion Preoperative mechanical bowel preparation did not reduce the occurrence of postoperative complications of the patients with RC undergoing ICD.
ABSTRACT
Objective To make specific clear labels which can lead us to easily distinguish tube category,function,the drainage of fluid properties and so on,and to improve the safety of patients tube management.Methods Using BarTender software to create labels format,and printing out all kinds of the labels by bar code printer,pasting around at suitable locations.Results Labels designed and printed by Bar-Tender software could be more efficient,accurate and clear to mark patients’drain,which avoided illegible writing.Conclusion Labels de-signed and printed by BarTender software can help doctors and nurses identifying the tube and handover management.
ABSTRACT
Objective To explore the syphilis epidemiological characteristics of blood recipients in Xinyang ,reduce medical dis‐putes and prevent hospital infection .Methods The gender ,age ,occupation ,education and other data of 16 429 blood recipients in our hospital were collected .Then we performed statistical analysis on the test results of syphilis antibodies to all kinds of people . Results Out of 16 429 samples ,137 cases were detected positive ,the prevalence was 0 .83% .Among them ,there were 70 males ,ac‐counting for 0 .74% male patients ,67 females ,accounting for 0 .96% female patients ,and there was no significant difference be‐tween the male and female patients(P>0 .05) .Syphilis infection in different age groups had significant difference(P<0 .05) .Mean‐while ,linear trend test suggested that syphilis infection rate increased with age(P<0 .01) .Different cultural level also had different infection rate of syphilis ,the higher cultural level ,the lower infection rate .Among non‐employed persons and farmers the prevalence of syphilis was highest .In contrast ,the prevalence was lowest among students .Conclusion Syphilis infection rates were not the same among different kinds of people ,and the syphilis test should be strengthened to blood recipients .
ABSTRACT
Objective To explore the role of mammalian target of rapamycin (mTOR) complex in the adriamycin induced the podecytes.Methods 1 μmol/L adriamycin (ADM) was used to induce mice podocytes for 24 hours and detected the apoptosis ratio,podosytes damage markers (Desmin) and the related expression of mTOR,then the role of mTOR was analysized in ADM induced podosytes.Results 1 umol/L ADM induced mice podosytes for 24 hours can make the podocytes damage.Compared with control group,podosytes activity declined(t =28.68,P ＜ 0.001),apoptosis rate increased both early (t =10.24,P =10.24) and late (t =4.26,P =4.26),and Desmin expression increased(t =6.16,P ＜0.001).mTOR expression decreased in ADM group.Compared with control group,both mTOR and phosphorylation mTOR expression decreased (t =3.57,P =3.57).mTOR downstream target molecular S6K1 and 4ebpl mRNA expression decreased(t =18.28,P ＜ 0.001).Conclusion ADM can make podosytes damage and the mechanism of ADM induced podosytes damage may be related to the decreasing mTOR and the low activity of mTOR.
ABSTRACT
Objectives To investigate the effect of matrine (MAT) on adriamycin (ADR) induced podocyte injury in vitro and explore the function of the mammalian target of rapamycin (mTOR) protein signaling pathway during the intervention. Methods ADR (1μmol/L) was used to induce the model of podocyte injury and then the podocytes were intervened by 10, 20 and 40μg/ml MAT for 24 hours. The viability and apoptosis rate of podocytes, mRNA and protein expressions of desmin and mTOR were detected. The effect of different concentrations of MAT on ADR-induced podocytes was analyzed. Results Com-pared with the control group, declined viability of podocytes (P<0.001), increased percentage of apoptotic podocytes (P<0.001), and increased expression of damage marker desmin (P=0.002) were observed in ADR group. In ADR group, after intervention with MAT of 10-40μg/ml, increased viability of podocytes (P<0.05), decreased percentage of apoptotic podocytes (P<0.05), and decreased expression of damage marker Desmin were found (P<0.05). The protein expression of mTOR and phosphorylation state of mTOR (p-mTOR) decreased in ADR induced-podocytes (P<0.05), and after intervention with MAT of 10-40μg/ml, the expression of mTOR and p-mTOR increased (P<0.05). The expression of mTOR downstream target protein s6k1 and 4EBP1 mRNA decreased in ADR group (P=0.071), while increased after intervention with MAT of 10-40μg/ml (P<0.05). Conclusions 10-40μg/ml MAT have protective effects on ADR-induced podocytes in vitro. The protection mechanism may be related to mTOR signaling pathway.
ABSTRACT
The mammalian target of rapamycin (mTOR)is a evolutionary conserved serine/threonine kinase that catalytics specific substrates and regulates cellular basic physiological events,such as growth,proliferation,autophagy and protein translation.It plays an important role in the regulation of cancer,diabetes and a variety of kidney diseases.Most of glomerular diseases are resulted from the podocytes and filtration barrier damage.Studies have suggested that there is a close relationship between mTOR and podosytes damage,but specific mechanism of regulation is not clear now.This review discusses the regulatory mechanism of mTOR kinase and its role in the glomerular disease to provide new ideas for understanding of glomerular disease pathogenesis.
ABSTRACT
Objective: To study angiogenesis and its influencing factors in human non-small cell lung cancer(NSCLC). Methods: The values of intratumor microvessel density(IMVD) in 95 cases of NSCLC were determined and its correlation with pathological parameters was analyzed. The relationship between IMVD and expressions of MMP-2,MMP-9,TIMP-2,VEGF,b-FGF,CD44v6,NOS2,NOS3 and E-cad in NSCLC was assessed. Results: There was active tumor angiogenesis of NSCLC, and the values of IMVD were correlated with clinicopathological stages of NSCLC and lymph nodes metastasis. The values of IMVD in positive expressions of VEGF, b-FGF, MMP-2, TIMP-2,CD44v6,NOS2 and NOS3 were significantly higher than that in negative expressions, opposed to the expression of TIMP-2 and E-cad. Conclusion:IMVD is a valuable marker for evaluating stages and metastasis of NSCLC. MMP-2, TIMP-2, VEGF, b-FGF, CD44v6, NOS2, NOS3 and E-cad may take part in the regulation of angiogenesis in NSCLC.
