Zuckerkandl tubercle is the extension of thyriod gland. For the past few years, more and more surgeons and anatomists have become interested in it. Clinically, surgeons usually rely on specified anatomical landmarks to avoid injuries to the recurrent laryngeal nerve, including the laryngeal branches and the superior parathyroid in thyroid surgery, such as the bottom corner of the thyroid cartilage, the inferior thyroid artery, lower pole of thyroid, tracheoesophageal groove, suspensory ligament of thyroid gland and so on. As the specified landmarks, they have several common characteristics:on the one hand, their location should be constant; on the other hand, they should be easy to observe and touch, meanwhile convenient and practical.As a new anatomical landmark, Zuckerkandl tubercle is in accordance with the above characteristics and prevalent in the population. Therefore, Zuckerkandl tubercle could become an important landmark to identify the the recurrent laryngeal nerve, including the laryngeal branches and the superior parathyroid in thyroid surgery. This essay aims to briefly analyze the role of Zuckerkandl tubercle in thyroid surgery.

Objective To explore the characteristics and effects of interventional therapy of transplant renal artery rupture of donation after citizens death (DCD).Method Among 28 cases of DCD renal transplantations (from February 2012 to December 2013),the transplant renal artery rupture occurred in 4 cases.Vascular complications were treated with the guide wires to place stents in the pseudoaneurysms or bleeding period.Result Pseudoaneurysms occurred in 2 cases,and they were successfully discharged after interventional treatment.In the rest two patients,the artery residual ruptured and bled after the nephrectomy,and they recovered after interventional treatment to stop bleeding.Conclusion For kidney transplant recipients,the DCD postoperative infection is risky.Some transplant kidneys have local infection and erosion of renal artery,which causes arterial hemorrhage.The interventional treatment of transplant renal artery pseudoaneurysms and rupture bleeding has the advantages of small trauma and instant effect,and can be used as an alternative treatment of open surgery.

Objective To explore the local application of immunosuppressant in improving the survival rate of the transplanted islet cells and systemic side effects.Methods The streptozocin of 200 ms/kg was injected into the abdominal cavity of the Wistar rats，the blood sugar was tested after 48，and 72 hours，and the rats with two consecutive measurements ≥20 mol/L were taken as the experimental animal model.The dose of pancreatic islet cells transplanted into the abdominal cavity was 8 000 IE,/kg，and that of cyclosporine dosage was 1.5 mg/(100 g·d).The pancreatic islet cells were divided into three groups：(1)systemic immunosuppressive agents through stomach lavage with the intraperitoneal injection of microencapsulated islet cells；(2)pure intraperitoneal injection of microencapsulated islet cells；(3)intraperitoneal injection microencapsulated activated carbon particles loaded with immunosuppressants，and mieroencapsulated islet cells.Changes of blood glucose and pathological in rats after transplantation were detected.Results The blood glucose of group 3 and group 1 showed no significant difference(P＞0.05)，as well as compared with group 2(P＞0.05).But the local application of immune agents could prolong the effective time of the islet cells and attenuate the fibrotic extent of the surrounding islets when compared with the control group,the C peptide level in applicating immunosuppressive agents group was significantly hisher in the immunosuppressive group than the pure transplantation group.ConclusionCompared with the systemic immune suppression via stomach lavage，local application of slow-release immunosuppressive agents showed the same effects of activated carbon particles，with a prolonged the effective time of islet cell and reduced topical side effects in the latter.

Objective To summarize the clinical efficacy of renal transplantation from donors of donation after brain death (DBD) complicated with acute kidney injury (AKI). Methods Fifty-nine DBD donors successfully undergoing renal transplantation were recruited in this investigation. According to the Scr level upon admission of intensive care unit (ICU), DBD donors were divided into the AKI group (n=14) and control group (n=45). A total of 101 recipients were assigned into the AKI group (n=23) and control group (n=78) correspondingly. The organ donation conditions of 59 donors were summarized. Main parameters of the donors before organ procurement were statistically compared between two groups. Postoperative kidney function, hospitalization condition and clinical outcomes of the recipients were statistically compared between two groups. Results Among 59 donors, 14 cases (24%) suffered from AKI. Two donors received continuous renal replacement therapy during organ maintenance. Compared with the donors in the control group, the APACHE Ⅱ score of the donors was significantly higher (P<0.05), the incidence of central diabetes insipidus was considerably higher (P<0.01), the Scr levels at admission of ICU and before organ procurement were significantly higher (both P<0.01) and the amount of urine at 24 h before organ procurement was dramatically less in the AKI group (P<0.01).Compared with the recipients in the control group, the Scr levels at postoperative 2 and 3 d were significantly higher (both P<0.05), the length of hospital stay was considerably longer (P<0.01) and the hospitalization expanse was significantly higher in the AKI group (P<0.05). No statistical significance was observed in the postoperative delayed recovery of renal graft function, incidence of acute rejection, infection and rehabilitation dialysis in the recipients between two groups (all P>0.05). At 3 months after transplantation, the recipients in two groups were discharged and the graft survival rate was 100%. Conclusions For renal transplantation from DBD donors complicated with AKI, active measures should be taken to maintain the organ and relieve the AKI, which yields similar clinical efficacy to renal transplantation from non-AKI donors and widens the origin of kidney graft.
