Objective To investigate the angiogenesis,apoptosis and their mechanisms in septic mice with myocardial injury.Methods Forty male C57BL/6 mice aged 8 weeks were randomly ( random number) divided into two groups:the sepsis group and the control group.The mice of sepsis group were treated with lipopolysaccharide (LPS) ( 10 mg/kg Intraperitoneal injection) while the mice of control group were treated with saline solution instead (10 mg/kg Intraperitoneal injection).Cardiac function of mice (n =40) was evaluated with ultrasound 6 hours after LPS administration.Subsequently,the tissues of heart,lung and kidney of mice (n =6) were taken and treated with Haematoxylin -Eosin staining (H&E) in order to observe the pathological changes and verify the successfulness of modeling.Immunohistochemistry staining with PECAM - 1 and α - SMA was used to identify the angiogenesis in the heart ( n =3 ),while the TUNEL apoptosis assay was applied for detecting the myocardial cell apoptosis ( n =3 ).The mRNA was extracted from heart tissue (n =6) to observe the expression of HIF-1 ot which was proved to be an angiogenesis factor.All the results were analyzed by independent sample t - test.Results Compared to the control group,mice in the sepsis group showed increased in thickness of left ventricular diastolic anterior wall ( t =- 4.60,P ＜ 0.05 ) and thickness of left ventricular systolic anterior wall (t =-3.24,P ＜0.05 ) along with decrease in left ventricular end diastolic diameter ( t =3.57,P ＜ 0.01 ) and stroke volume ( t =5.51,P ＜ 0.01 ).Immunohistochemistry staining with alpha - SAM antibody revealed increase in cardiac angiogenesis in the sepsis group (t =- 11.00,P ＜ 0.01 ).TUNEL apoptosis assay demonstrated apoptosis of the cardiomyocytes [ sepsis group versus control group:( 191.31 ±5.41 ) vs ( 52.24 ±4.32) ] and RT - PCR showed an increase in the expression of HIF - 1 alpha in the mice of the sepsis group ( t =- 8.12,P ＜0.05) Conclusions There were apparent myocardial angiogenesis,apoptosis and cardiac dysfunction in septic animal models.HIF-1α might play a role in the angiogenesis pathway.

Objective To evaluate if the flexible ureteroscopy could treat stones located in lower calyx with the infundibulopelvic angle (IPA) less than 30°.Methods Thirty-six patients with inferior caliceal calculi on whom flexible ureteroscopic procedures were performed between November 2009 and June 2015 were reviewed.The mean age of the patients was 52.1 years (34-71),with the mean stone diameter of (1.5 ± 0.8) cm (1.2-2.6 cm).IPA was smaller than 30° in all 36 cases,which confirmed by CTU examination.IPA was less than 10° in 15 patients,between 11 ° and 20° in 13 patients and between 21 ° and 30° in 8 patients.Results The success rate was 63.9％ (23/36 patients) in patients with IPA smaller than 30° after first session of procedure,and the stone free rate reached 100％ after the second session of procedure.The mean operation duration was (95.5 ± 31.4) min(51-127 min).The mean hospital stay after operation was(4.1 ± 1.2)days (3-5 days).No major complications were recorded and no patients needed to convert to open surgery.Double J tube was removed after 4 weeks postoperatively.Patients were followed up for 4-12 months,during which ultrasound and CT scan were used for stone detection.Conclusions The small IPA (＜30°) negatively affected the SFR in the first session operation.However,its negative effect was solvable by using modern endoscopes.A complete stone clearance was achievable even in case of unfavorable anatomic conditions in experienced hand.

Percutaneous nephrostomy was applied in some other urologic diseases and the efficacy was evaluated. Percutaneous nephrostomy for percutaneous nephrolithotomy (PNL) was performed in patients with various renal, perinephric and bladder diseases (n=79). The tract establishment, operation duration and complications were observed and the efficacy was assessed. The results showed that the tracts were successfully established in 79 cases. The operation lasted 4-20 min. 12F-16F single tract was established in nephrohydrop patients and 16F-20F single or multiple tracts were established in patients with pyonephrosis, renal cortical abscess, renal cyst and perinephric abscess. During dilation, no leakage of liquor puris was noted. Establishment of 18F single tract was achieved in one urinoma patient. In two patients with foreign body in kidney, the foreign bodies were removed via established 14F single tract. 18F tracts were established in 2 patients with bladder contracture, which was followed by the placement of 16F balloon urethral catheter for drainage. No complications, such as massive bleeding, intestinal injury and spreading of infection took place in our series. All the patients were followed up for 2-12 months. No long-term complications such as dropping of drainage tube occurred. It is concluded that as a minimally invasive technique, percutaneous nephrostomy has the advantages of convenience, simplicity and causing less complications and can be used for various urologic diseases.

Objective To evaluate the safety and efficacy of transcatheter arterial embolization (TAE) combined with argon-helium cryoablation in treating small renal cancers. Methods During the period from February 2008 to July 2013, a total of 44 patients with small renal cancer were treated with TAE and argon-helium cryoablation at The Medical Imaging Department of Nanjing General Hospital of Nanjing Military Area Command. The renal function was reexamined one month after the treatment. Contrast-enhanced CT or MRI was performed in all patients within 1-3 months after the treatment. By using mRECIST, the therapeutic efficacy was evaluated. All patients were followed up for 12-46 months (mean 28 months). Results A total of 48 lesions in the 44 patients were treated with sequential therapy of TAE and argon-helium cryoablation. Of the 48 lesions, complete remission (CR) was achieved in 38, partial remission (PR) in 6 and stable disease (SD) in 4, the remission rate (CR+PR) was 91.7%. No severe complications occurred in all patients, except one who developed localized hemorrhage during the performance of argon-helium cryoablation, which was improved after symptomatic medication. The mean postoperative hospitalization time was 4 days. Three patients were lost to follow-up, one patient died of esophageal cancer-related complication. The remaining patients were survival during the follow-up period, among them recurrence occurred in five within 13-22 months after the treatment, and the sequential therapy of TAE and argon-helium cryoablation had to be carried out once more. Conclusion For the treatment of small renal cancers, the sequential therapy of TAE combined with argon-helium cryoablation is minimally-invasive, safe and effective, and TAE that is performed before argon-helium cryoablation can reduce the incidence of bleeding occurring in the freezing process. Therefore, this technique should be recommended in clinical practice.

Objective To monitor the renal pelvic pressure and to investigate its clinical significance during retrograde flexible ureteroscopic lithotripsy (RFUL).Methods The data of renal pelvic pressure measured in 60 cases of RFUL with the mean irrigation pump speed and pressure of 30 ml/min and 30 mmHg were analyzed retrospectively.The influence factors of renal pelvic pressure and its correlation with postoperative fever were analyzed.Renal pelvic pressure was measured by baroceptor,which was connected to PHILIP-MP4 monitor IBP channel and ureteric catheter positioned in renal pelvis through a dual channel ureteral access sheath (UAS).The renal pelvic pressure data was collected and analyzed in every 2 seconds by computer.The 60 cases were divided into 3 groups according to their intra-pelvic pressure situations:normal pressure group(NP,IPPmax ≤30 mmHg),high pressure group(HP,IPPmax＞30 mmHg,but high pressure duration≤ 10 min),and backflow pressure group(BP,IPPmax＞30 mmHg and high pressure duration＞ 10 min).Results The baseline intra-pelvic pressure (IPP0) and max imum intra-pelvic pressure (IPPmax) were (13.2±5.6) mmHg and (95.6±2.3) mmHg respectively.IPP levels during the RFUL were significantly higher than the IPP0(P＜0.001).There were 32,17 and 11 cases in NP,HP and BP groups,respectively.There were 6 cases with fever higher than 38.5 ℃ (10％),in which there were 1 case in NP,1 case in HP group and 4 cases in BP group.The postoperative fever rate in NP,HP and BP group were 3％,6％ and 36％ respectively,which were significantly different between groups(P＜0.01).There were 12 cases with procalcitonin ＞0.1 ng/ml and 8 cases with procalcitonin ＞0.5 ng/ml,in which 2 cases in HP group and 6 cases in BP group.Conclusions RFUL would result in a temporal elevated intrapelvic pressure greater than 30 mmHg.Postoperative fever is relevant with renal perfusion pressure and perfusion time.It's necessary for the surgeons to adjust the perfusion pressure during operation.

Objective To compare the therapeutic effect of retrograde ureteroscopic Ho:YAG laser lithotripsy (UHL) and percutaneous nephrolithotripsy (PCNL) in treating patients with renal calculi of ≤3 cm.Methods From Feb.2008 to Apr.2011,a total of 109 cases (117 renal calculi in total) treated by either PCNL (50) or UHL (67) were retrospectively analyzed.Operative time,stone free rate,postoperative hospital stay,hospitalization expenses and complications were compared in the 2 groups.Results The mean stone burden of the UHL group and PCNL group was 2.5 cm (1.5-3.0) cm and 2.4 cm (1.3-3.0) cm,respectively.There was no significant difference in two groups.In UHL group,operations were performed successfully in all 67 calculi,of whom,43 patients needed combination of flexible ureteroscopy to break the stone fragments falling into the renal calices.No serious complication was recorded except postoperative fever in 3 cases.In PCNL group,all patients had been successful operated.Postoperative fever occurred in 2 cases.Obvious intraoperative and postoperative haemorrhage appeared in 1 case,and cured by selective renal artery embolization.The operation time of the UHL group and PCNL group was (117.0±36.5) min and (90.0±18.3) min respectively,and had no significant difference in two groups (P＞0.05).The stone free rate of the UHL group and PCNL group was 94％ (63/67) and 92％ (46/50) respectively,and had no significant difference in two groups (P＞0.05).Hemoglobin decline of the UHL group and PCNL group was (0.3±0.1) g/L and (20.6±8.1) g/L,and had significant difference in two groups (P＜0.05).Postoperative hospital stay of the UHL group and PCNL group was (5.0±2.4) day and (7.0±3.7) day,and had statistical difference in two groups (P＜ 0.05).Hospitalization expenses of the UHL group and PCNL group was (15 477.0±754.3) RMB and (27 453.0± 1763.5) RMB,and had statistical difference in two groups (P＜0.05).Conclusions Although UHL and PCNL have similar curative effect in treating renal stones of less than 3 cm,UHL have the advantages of lcss trauma and complication,lower expenses and fewer hospital stay.In treating renal stones of smaller than 3 cm,especially in the contraindication of PCNL,UHL may be a better choice.

Objective: To improve the awareness of emergency biliary obstruction (BO) disease, and to further improve the diagnosis and treatment ability of BO patients. Methods: Data of the etiology, clinical manifestations, imaging data, laboratory tests, and emergency treatment outcomes in 63 BO patients were retrospectively analyzed. Results: Common bile duct stones were the most common cause of BO patients (63.49%), followed by cholangiocarcinoma (19.05%); the most common clinical manifestations of BO patients were jaundice (90.48%), abdominal pain (87.30%), and fever (53.97%); the diagnostic ability of computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP) in patients with BO was significantly higher than that of ultrasound (P<0.05), but there was no significant difference between CT and MRCP (P=1.000); compared with benign group, hemoglobin and albumin in malignant group were significantly lower, while total bilirubin and direct bilirubin were higher, with statistically significant difference (P<0.05). Most patients in BO patients improved after treatment, and the mortality rate of BO patients was 3.17%(2/63) at the end of emergency visit. Conclusions Common bile duct stones and cholangiocarcinoma are still the most common causes of emergency BO patients. The most common clinical manifestations of patients with emergency BO are jaundice, abdominal pain, and fever. Better than abdominal ultrasound, CT and MRCP have comparable diagnostic capabilities in the diagnosis of emergency BO patients. Anemia, hyperbilirubinemia and hypoproteinemia are alarm indicators for malignant tumors in emergency BO patients. Most patients can temporarily get better at the end of emergency visit.
