BACKGROUND: Presently, the kidney source is limited. Urinary fistula-induced nephrectomy of transplanted kidney is regrettable. Reasonable diagnosis of urinary fistula should be paid great attention by workers of organ transplantation. OBJECTIVE: To study the diagnosis and treatment of the urinary fistula in kidney transplantation patients. METHODS: The clinical data of 16 patients with the urinary fistula following kidney transplantation, who was recruited from the Organ Transplantation Center, Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA, were retrospectively analyzed. RESULTS AND CONCLUSION: The morbidity of the urinary fistula following kidney transplantation was 1.26%, the conservative treatment were used to 13 cases of simple urinary fistulas, 11 of 13 cases were successful (84.6%). 2 case failed (15.4%), pedicled omentum grafts were successful used to treat 3 cases of complex urinary fistulas after renal transplantation by one operation. Intensive care and active measures should be given to the urinary fistula patients after kidney transplantation. The key to the successful treatment involved with the diagnosis in early stage and the correct measures. With biological characteristics of omentum, applying pedicled omentum grafts to repair complex urinary fistulas and simple urinary fistulas which were failure of the conservative treatment after renal transplantation has advantages as followings, convenient to draw material, recovering tissue quickly and low recurrence rate. It is fit for clinic.

Objective To study spiral CT features and pathological basis of nodular goiter ,so that to improve the diagnostic accuracy of nodular goiter.Methods CT findings in 34 patients with nodular goiter confirmed by pathology were retrospectively analyzed and compared with pathological findings. Results Thyroid density in the patients with NG was lower than that in the normal. There was no statistically significant difference in the density between single and multi-NG. Most lesions(28/34) were multiple, round or oval, with different size and smooth edges. The density of majority lesions was lower than nearby normal tissue. Most lesions (27/34) were uniform in density. Central necrosis(5/34)often appeared in the bigger lesions(diameter＞3.0 cm). The CT value of the lesions was increased (47.1±42.2) HU after enhancement,but lower than surrounding thyroid tissue. Calcifications in the lesions(6/34)were puncticular,plaque or crustiform. Single or multiple cystic-solid or solid nodules could be seen in pathology, without a continuous capsule in the majority. Some patients (5/13) with single NG shown on imaging study were multi-NG in the pathology. Three cases of diffuse NG showed by CT were malignant in pathology. Conclusion There are certain characteristics for NG on spiral CT. Comprehensive evaluation may improve the accuracy of CT diagnosis.

Objective To study the effects of a cirrhotic environment on the metastasis of liver cancer in mice.Methods Male BALB/c mice were randomly assigned to two groups:cirrhosis group and control group.The cirrhosis group was treated by an injection of carbon tetrachloride intraperitoneally.H22 liver cancer cells were directly implanted under the capsule of each group after cirrhosis was established.The animals were sacrificed at 1,2,and 3 weeks after the operation.The metastatic behavior of the cancer cells was observed by the naked eye and microscopically.Additionally,the adhesion ability of the liver was assessed by measuring the expression of vascular cell adhesion molecule 1 (VCAM-1),E-selectin,and E-cadherin.Results After the operation,the cirrhosis group showed an obvious metastatic tendency in both intrahepatic (14/19) and extrahepatic ways (4/19),compared with the control group's intrahepatic (5/17) and extrahepatic ways (1/17) (P＜0.05).Immunohistochemisty for VCAM-1 and E-selectin showed a significant increase in the cirrhosis (P＜0.05).However,there was no difference observed in the E-cadherin between the cirrhosis and control group.Conclusion A cirrhotic liver environment may promote the metastasis of liver cancer cells by increasing the ability of liver adhesion.

Objective To analyse the effect of octreotide combined with compound coenzyme on Th17/CD4 +CD25 +Foxp3 + regulatory T cells imbalance in patients with purulent appendicitis.Methods 150 patients with acute suppurative appendicitis were randomly divided into experimental group and control group, 75 cases in each group.Patients of two groups underwent appendicitis laparoscopic resection, then the control group were given conventional treatment and experimental group were given subcutaneous injection of octreotide on the basis of conventional treatment.Th17, CD4 +CD25 +Foxp3 +regulation T cells ( Treg) , and Th17 /Treg balance were analyzed.ResuIts Compared with control group, Th17/Treg imbalance of experimental group recovered better: the proportion of Th17, Treg, and Th17/Treg ratio decreased (P<0.05); the expression levels of related transcription factor, RORγt and Foxp3 mRNA decreased (P<0.05); serum cytokine (IL-4, IL-6, IL-10, IL-17, IL-23 and TGF beta) and C-reactive protein (CRP) content decreased (P<0.05);serum interferon gamma (IFN-gamma) content increased (P<0.05).ConcIusion Octreotide combined with compound coenzyme could correct Th17/Treg imbalance in suppurative appendicitis patients, improve the immune function of patients and affect the prognosis of patients.

Objective To identify the dose-volumetric parameters associated with acute bone marrow suppression in concurrent chemoradiotherapy for cervical cancer,and provide the reference standard for the radiotherapy planning.Methods In total,155 patients concurrently receiving chemoradiotherapy for cervical cancer were enrolled in this study.The pelvis was contoured for each patient in radiotherapy treatment planning system and divided into three subsites:lumbosacral spine,ilium,and lower pelvis.The pelvic dose volume parameters were analyzed using univariate analysis (Chi-Square and t test),and multivariate analysis (Logistic regression model).Dose volume parameters include V5,V10,V15,V20,V25,V30,V35,V40,V45,V50 and the average dose (D).Results The percentage of patients that developed acute bone marrow suppression (≥ grade 2) was 87.7％ (136/155).The univariate analysis revealed that pelvic V5,V10,V15,V,0,ilium V15,lower pelvis V15 of patients with acute bone marrow suppression (≥ grade 2) were significantly higher than those of ＜ grade 2 patients (t =-2.277,-2.142,-3.475,-2.018,-2.963,-2.741,P ＜0.05).Multiple regression analysis indicated that pelvic V15 was associated with acute bone marrow suppression (OR =1.728.P ＜ 0.05).The threshold of pelvic V15 was 88％ as determined by receiver operating curve (ROC).Conclusions The results show that Pelvic V15 is associated with acute bone marrow suppression in concurrent chemoradiotherapy for cervical cancer and is thus an independent risk factor.To better predict and control acute bone marrow suppression,pelvic V15 should be carefully controlled below 88％ in treatment planning to reduce the incidence of acute bone marrow suppression.

Good self-management behaviors can control symptoms of the patients with osteoarthritis, improve the patients' joint function and quality of life. Patients' self-management behaviors have been impacted by disease knowledge, self-effcacy, emotional state, and social support. All the above factors should been taken into full consideration when intervening. Self-management program is an intervention mode which can improve patient self-management behaviors and promote patient health.

Objective To investigate whether the nod-like receptor (NLR) pathway is involved in protection of hydrogen sulfide (H2S) preconditioning during renal ischemia reperfusion.Methods Male Wistar rats were randomly divided into 3 groups:sham operation (Sham) group,renal ischemia/ reperfusion (I/R) group subjected to occlusion of left renal pedicle for 45 min then reperfusion for 24 hours,and sodium hydrosulfide (NaHS) preconditioning group with continuous infusion of NaHS (300 nmol/min) by left renal artery for 15 min before I/R treatment.Renal injuries were evaluated by HE staining.The protein levels of NOD1,NOD2,nuclear NF-κB P65 and caspase-1 were analyzed by Western blot assay.The protein level of MCP-1 and IL-1β expressions was determined by immunohistochemical staining assay.Cell apoptosis were evaluated by Tunel staining assay.Results In I/R group,the renal NOD1 and NOD2 protein expressions were upregulated.Moreover,the nuclear NF-κB P65 expression was also elevated with an increase in its target genes-MCP-1 and IL-1β (All P ＜ 0.01).HE staining revealed the existence of acute tubular necrosis in I/R kidney.TUNEL staining revealed more apoptotic cells in risk zone with the activation of caspase-1 of I/R-treated kidney(P ＜0.01).NaHS preconditioning reversed I/R-induced increase in the expression of NOD1 and NOD2(P ＜0.05).NaHS preconditioning also reduced I/R-induced activation of NF-κB P65 (P ＜ 0.05) and upregulation of MCP-1 and IL-1β (P ＜ 0.01).Moreover,NaHS preconditioning attenuated inflammation,repressed caspase-1 activation and reduced apoptotic cells after I/R.Conclusion Hydrogen sulfide preconditioning can alleviate renal ischemia/reperfusion injury by Nod-like receptor dependent on inflammatory pathway.
