Objective To evaluate the clinical value of holographic image navigation in urological laparoscopic and robotic surgery.Methods The data of patients were reviewed retrospectively for whom accepted holographic image navigation laparoscopic and robotic surgery from Jan.2019 to Dec.2019 in Beijing United Family Hospital and other 18 medical centers,including 78 cases of renal tumor,2 cases of bladder cancer,2 cases of adrenal gland tumor,1 cases of renal cyst,1 case of prostate cancer,1 case of sweat gland carcinoma with lymph node metastasis,1 case of pelvic metastasis after radical cystectomy.All the patients underwent operations.In the laparoscopic surgery group,there were 27 cases of partial nephrectomy,1 case of radical prostatectomy,2 cases of radical cystectomy and 2 cases of adrenalectomy.In the da Vinci robotic surgery group of 54 cases,there were 51 cases of partial nephrectomy,1 case of retroperitoneal lymph node dissection,1 case of retroperitoneal bilateral renal cyst deroofing and 1 case of resection of pelvic metastasis.There were 41 partial nephrectomy patients with available clinical data for statistic,with a median age of 53.5 years (range 24-76),including 26 males and 15 females.The median R.E.N.A.L score was 7.8 (range 4-11).Before the operation,the engineers established the holographic image based on the contrast CT images and reports.The surgeon applied the holographic image for preoperative planning.During the operation,the navigation was achieved by real time fusing holographic images with the laparoscopic surgery images in the screen.Results All the procedures had been complete uneventfully.The holographic images helped surgeon in understanding the visual three-dimension structure and relation of vessels supplying tumor or resection tissue,lymph nodes and nerves.By manipulating the holographic images extracorporeally,the fused image guide surgeons about location vessel,lymph node and other important structure and then facilitate the delicate dissection.For the 41 cases with available clinical data including 23 cases of robotic-assisted partial nephrectomy and 18 cases of laparoscopic nephrectomy,the median operation time was 140 (range 50-225) min,the median warm ischemia time was 23 (range 14-60) min,the median blood loss was 80(range 5-1 200) ml.In the robotic surgery group,the median operation time was 140 (range 50-215)min,the median warm i schemia time was 21 (range 17-40)min,the median blood loss was 150(range 30-1 200)ml.In the laparoscopic surgery group,the median operation time was 160(range 80-225)min,the median warm ischemia time was 25 (range 14-60)min,the median blood loss was 50 (range 5-1 200) ml.All the patients had no adjacent organ injury during operation.There were 2 cases with Clavien Ⅱ complications.One required transfusion and the other one suffered hematoma post-operation.However,the tumors were located in the renal hilus for these 2 cases and the R.E.N.A.L scores were both 11.Conclusions Holographic image navigation can help location and recognize important anatomic structures during the surgical procedures..This technique will reduce the tissue injury,decrease the complications and improve the success rate of surgery.

Objective: To explore the diagnostic value of serum NSE, S100B protein and myocardial zymogram in premature infants with intrauterine infection. Methods: From January 2016 to December 2017, 60 preterm infants with intrauterine infection in the Integrated Chinese and Western Medicine Hospital of Wenzhou were selected in the study.According to whether brain injury occurred, they were divided into brain injury group (28 cases) and non-brain injury group (32 cases). Serum NSE content was detected by chemiluminescence method, serum S100B protein level was detected by enzyme linked immunosorbent assay (ELISA), and serum CK and HBDH levels were detected by automatic biochemical analyzer.The serum levels of NSE, S100B, CK and HBDH were compared between the two groups, the combined diagnostic efficacy of NSE+ S100B protein+ CK+ HBDH was analyzed, the correlation of serum NSE, S100B protein, CK, HBDH with brain injury wasanalyzed. Results: The levels of serum NSE [(2.43±0.54)μg/L] and S 100B [(14.36±3.21)ng/L] in the brain injury group were higher than those in the non-brain injury group [(0.97±0.27)μg/L and (8.10±1.87)ng/L] (t=13.498, 9.370, all P<0.05). The levels of serum CK [(437.64±54.12)U/L] and HBDH [(387.91±56.45)U/L] in the brain injury group were significantly higher than those in the non-brain injury group [(183.54±32.58)U/L and (174.3±26.63)U/L] (t=22.347, 19.126, all P<0.05). The sensitivity and specificity of the combined diagnosis of NSE+ S100B protein and myocardial zymogram were higher than those of each single index.Serum NSE, S100B protein, CK and HBDH were positively correlated with brain injury. Conclusion The elevation of serum NSE, S100B protein and myocardial zymogram in preterm infants with intrauterine infection after birth has certain clinical significance in judging whether brain injury occurs or not.

Objective To explore the clinical efficacy and side effects of intraperitoneal perfusion of verapamil and chemotherapeutic drugs in treating patients with gastric cancer after operation.Methods Totally 184 gastric cancer patients accepted radical surgery with postoperative classification (pT1/2/3/4N2/3M0) were randomly divided into control group (n =58) and treatment group (n =126).For the post-gastrectomy chemotherapeuric treatment,1 g of 5-fluorouracil and 70 to 90 mg of cisplatin were administrated for the patients in the control group,while 1 g of 5-fluorouracil,70 to 90 mg of cisplatin and 25 mg of verapamil were given to the patients in the treatment group.Patients in both groups received intravenous administration of 20 to 30 mg of doxorubicin 3 ～ 5 hours before the intraperitoneal chemotherapy,and 0.1 g of leucovorin 30 minutes prior to the intraperitoneal chemotherapy.On the second day,intraperitoneal chemotherapy of 0.5 to 0.75 g 5-fiuorouracil was given to all patients for 3 to 5 days.The disease-free survival rate,overall survival rate,disease-free survival (DFS),overall survival (OS),peritoneal recurrence rate,liver metastasis rate,gastric remnant recurrence rate,adverse reactions were examined and recorded at the time points of 12 and 24 months after the chemotherapy treatment.Results In the treatment group,disease-free survival and overall survival rates at 12 and 24 months were significantly higher than those in the control group,and the median DFS and OS were significantly longer than the control group (P ＜ 0.05).In patients with regional lymph node staging (N2,N3),low differentiated adenocarcinoma,tumor diameter greater than 4-cm,the disease free survival rate and overall survival rate at 12 and 24-months were significantly higher than the control group,and the median DFS and OS were significantly longer than the control group (P ＜0.05).In the treatment group,intraperitoneal recurrence rate and liver metastasis rate at 12 and 24-months were significantly lower than the control group (P ＜ 0.05).There was no significant difference in recurrence rate of gastric stump between the control group and treatment group.Application of verapamil did not increase the incidence rate of adverse reactions.There were 8 patients with mild abdominal pain and 3 patients with incomplete intestinal obstruction,and all of them were cured after one week of treatment.Conclusion The intraperitoneal perfusion of verapamil and chemotherapeutic drugs can significantly increase the disease-free survival rate and overall survival rate,prolong the median DFS and OS,reduce the recurrence rate of intra-abdominal and liver metastasis rate in the gastric cancer patients at 12 and 24 months after chemotherapy.

Objective: To test the feasibility of drag-reducing polymers (DRP) for improving coronary microcirculation in a canine model in order to provide the experimental basis for treating myocardial microcirculation dysfunction. Methods: A total of 8 dogs received open-chest surgery and they had intravenous injections, in turn, with adenosine (ADN), DRP 250 mg/L and DRP+ADN. The function y=A × (1-e-βt) was used to calculate the myocardium capillary volume (A value), capillary velocity (β value) and myocardial blood lfow (A ? β value) by myocardial contrast echocardiography. Results: With DRP infusion, the A value in experimental canine was similar to the baseline condition,P>0.05; while theβ value and A ? β value were signiifcantly increased as (0.57 ± 0.10) 1/s vs (0.23 ± 0.03) 1/s,P<0.01 and (11.51 ± 1.96) VI/s vs (5.15 ± 0.86) VI/s,P <0.05 respectively. With combined infusion of DRP+ADN, the β value and A ? β value were similar to the baseline condition, bothP>0.05. Conclusion: DRP improved coronary microcirculation primarily by modulating the β value in experimental canine model, and hopefully, this unique hemodynamics could provide a new approach for treating myocardial microcirculation dysfunction.

Objective To verify the safety and advantages of total transperitoneal laparoscopic nephroureterectomy (ttLNU) in the treatment of upper urinary tract urothelial carcinoma (UTUC).Methods From Jun.2013 to Jun.2014,there were 13 UTUC patients treated with ttLNU,including 7 males and 6 females.The mean age was 70.4 ± 8.3 yrs,and BMI was 23.3±4.1.Of them,11 cases were diagnosed with renal pelvis carcinoma,6 in the left and 5 in the right.2 cases were diagnosed with left ureteral carcinoma.TNM stages were T1-T3N0M0.Patients were put on lateral position and the position was not changed during the operation.A ttLNU was performed,and the specimen was removed from the middle extended inferior umbilical incision.Results The mean operative time was 188±33 (150-240) min,the intraoperative blood loss was 150.5±60.1 (50-700) ml,and the time of out-of-bed activity was between 1 and 4 d.The mean postoperative drainage time was 6.8±4.6 (3-6) d.The mean postoperative bowel function recovery time was 1.5± 1.0 (2-4) d and postoperative hospital stay was 12.8±7.0 (3-27) d.The ttLNU procedures were successfully performed in all cases without conversion to open surgery.Pathological results showed urothelial carcinoma in all cases,including 8 high grade and 5 low grade.All the surgical margins were negative.The followed up was from 2 to 12 mon,and there was no tumor recurrence and metastasis found.Conclusions Total transperitoneal laparoscopic nephroureterectomy in the treatment of upper urinary tract urothelial carcinoma is characterized by short operative time,low blood loss,decreased trauma and quick recovery.This is a safe and effective treatment option for the treatment of upper urinary tract urothelial carcinoma.

Objective To investigate the partial safety of the recombinant adenovirus containing the triple-point mutants HIF-1αgene (Ad-HIF-1α-Trip)transfection in a rabbit model of hind limb ischemia. Methods After ligation of left femoral artery, 22 New Zealand whites rabbits were randomly divided into 3 groups: saline group(n=6), Ad-Null group(n=6) and Ad-HIF-1α-Trip group(n=10). After operation, saline, Ad-Null and Ad-HIF-1αwere injected intramuscularly respectively. The expression of transferred HIF-1αat mRNA level in the ischemic skeletal muscle and other important organs were detected by Real-time PCR 10 days after gene transfection. The body temperature, weight, blood, liver and renal function, as well as the myocardial enzymes were detected before operation, and on the 3th, 7th, 14th and 28th day after gene transfection, so that pathological changes could be observed. Results On the 10th day after gene transfection, obvious expressions of HIF-1αat mRNA level in the ischemic limb were found, but no expression in other important organs was detected in Ad-HIF-1α-Trip group. The blood routine, liver and renal function were all in the normal range (P > 0.05). No abnormalities were found in heart, liver, kidney, and lung HE transfection in Ad-HIF-1α-Trip group. Conclusion Single intramuscular injection of Ad-HIF-1α-Trip can be expressed obviously in the ischemic limb without detected damage of liver , cardiac and kidney.
