Objective To summarize the outcome in surgical management and medical therapy of aneurysm involved in Behcet’s disease. Methods From April 1977 to December 2004,7 patients (one female) were admitted. There were 4 false aneurysms in aortic isthmus, and 1 right subclavian artery pseudoaneurysm, and 1 right axillary artery false aneurysm, and 1 thoracicoabdominal multiple pseudoaneurysms. Surgical procedures included 4 aneurysmorrhaphys and patch angioplasties, 1 aneurysmorrhaphy and tube graft replacement, 1 covered stents and axillary to axillary artery bypasses, 1 aneurysmorrhaphy and right subclavian artery ligation. The other 3 cases survived. Results There were no hospital death, but there were 1 anastomotic aneurysm occurrence, 2 new aneurysms formation, 1 femoral artery occlusion at canal insertion site, and 1 bypass graft occlusion. Follow-up from 1 to 12 months, there were death in 4 cases. Conclusions Behcet’s disease could easily result in anastomotic aneurysm and/or new aneurysm or rupture occurrence. Based on location of lesion, selection of proper intervention, and combination with immunosuppression therapy, the satisfactory result could be obtained, therein, prosthetic graft replacement surpasses the patch angioplasty.
Objective To study the clinical value and surgical procedure of laparoscopic operation for interstitial tubal pregnancy. Methods Clinical data of 36 patients of interstitial tubal pregnancy treated by laparoscopic operation were retrospectively analyzed. Results All 36 patients were operated successfully, without conversions to laparotomy and intra- or post- operative complications. The operation time was 28-85 min(mean, 41min), and the length of stay in hospital postoperative was 3-6 d (mean, 4-5 d). Conclusion Laparoscopic operation for interstitial tubal pregnancy is safe and feasible.
ObjectiveTo investigate the expression of growth arrest-specific 5 (GAS5) mRNA and its clinical significance in hepatocellular carcinoma.MethodsThe expression of GAS5 mRNA in the hepatocellular carcinoma tissues and corresponding adjacent tissues were detected by real time-PCR. The relationship between the expression of GAS5 mRNA and clinicopathological characteristics were analyzed by SPSS 19.0 software.ResultsThe expression of GAS5 mRNA in hepatocellular carcinoma tissues was significantly lower than that of the adjacent tissues (P<0.01). The expression of GAS5 mRNA was related to tumor size, tumor number, lymph node metastasis, clinical TNM stage, alpha fetoprotein level, and tumor differentiation (P<0.05). Cox hazard model results showed that low expression of GAS5 mRNA was associated with poor prognosis (P<0.05).ConclusionGAS5 mRNA is expected to be a diagnostic and prognostic marker for patients with hepatocellular carcinoma.
Lower limb exoskeleton rehabilitation robots are used to improve or restore the walking and movement ability of people with lower limb movement disorders. However, the required functions for patients differ based on various diseases. For example, patients with weak muscle strength require power assistance, patients with spinal cord injuries require motion compensation, patients with gait abnormalities require gait correction, and patients with strokes require neural rehabilitation. To design a more targeted lower limb exoskeleton rehabilitation robot for different diseases, this article summarised and compared existing lower limb exoskeleton rehabilitation robots according to their main functions and the characteristics and rehabilitation needs of various lower limb movement disorders. The correlations between the functions of existing devices and diseases were summarised to provide certain references for the development of new lower limb exoskeleton rehabilitation robots.
Objective To investigate the effect of applying a tourniquet on perioperative blood loss and short-term effectiveness in primary total knee arthroplasty (TKA). Methods A total of 94 patients (94 knees) with osteoarthritis underwent primary TKA between September 2010 and December 2011, whose data met the inclusion criteria and were retrospectively analyzed. A tourniquet was used in 51 cases (group A), no tourniquet in 43 cases (group B). There was no significant difference in gender, age, affected side, body mass index, preoperative hemoglobin (Hb) level, range of motion (ROM), visual analogue scale (VAS), Hospital for Special Surgery (HSS) score, Western Ontario and McMaster University Osteoarthritis Index (WOMAC) between 2 groups (P gt; 0.05). The data were compared between 2 groups, including hematocrit (Hct), Hb, hidden blood loss, dominant blood loss, theoretical total blood loss, the operation time, hospitalization days, increasing rate of circumference length above 10 cm of the knee, VAS score, ROM, HSS score, and WOMAC score. Results Four cases (7.84%) of group A and 1 case (2.33%) of group B received blood transfusions, showing no significant difference (χ2=1.410, P=0.235). There was no significant difference in the Hb and Hct between 2 groups at 2 days after operation (P gt; 0.05). The dominant blood loss of group A was significantly less than that of group B (P lt; 0.05), while the hidden blood loss of group A was significantly more than that of group B (P lt; 0.05), but there was no significant difference in theoretical total blood loss between 2 groups (t=0.662, P=0.510). The operation time, hospitalization days, and VAS score at 3 days showed no significant difference between 2 groups (P gt; 0.05). The wound healed by first intention after operation without related complication. At 3 days after operation, the increasing rate of circumference length above 10 cm of the knee in group A was significantly higher than that of group B (t=9.435, P=0.000), but no significant difference at 7 days (t=0.462, P=0.645). At 3 and 5 days after operation, the ROM values in group B were significantly larger than those of group A (P lt; 0.05), but no significant difference at 7 days (t= — 1.279, P=0.204). The patients were all followed up 12-18 months (mean, 14.3 months). There was no significant difference in the HSS score between 2 groups at 1 year after operation (t=0.952, P=0.344), but significant difference was found in the WOMAC score between 2 groups (t= — 2.488, P=0.015). The X-ray films showed that the prosthesis was in good position, without loosening, subsidence, or osteolysis. Conclusion Application of a tourniquet in TKA increases hidden blood loss, and there is no obvious advantage in reducing transfusion rate compared with the non-tourniquet group, so it is recommended to reduce the time and pressure of the tourniquet for patients with high-risk of thrombosis.
Objective To calculate the recovery rate and enrichment factor and to analyse the correlation by measuring the concentrations of platelets, leukocyte, and growth factors in platelet-rich plasma (PRP) so as to evaluate the feasibil ity and stabil ity of a set of PRP preparation. Methods The peripheral blood (40 mL) was collected from 30 volunteers accorded with the inclusion criteria, and then 4 mL PRP was prepared using the package produced by Shandong Weigao Group Medical Polymer Company Limited. Automatic hematology analyzer was used to count the concentrations of platelets and leukocyte in whole blood and PRP. The enrichment factor and recovery rate of platelets or leukocyte were calculated; the platelet and leukocyte concentrations of male and female volunteers were measured, respectively. The concentrations of platelet-derived growth factor (PDGF), transforming growth factor β (TGF-β), and vascular endothel ial growth factor (VEGF) were assayed by ELISA. Results The platelet concentrations of whole blood and PRP were (131.40 ± 29.44) × 109/L and (819.47 ± 136.32) × 109/L, respectively, showing significant difference (t=—27.020, P=0.000). The recovery rate of platelets was 60.85% ± 8.97%, and the enrichment factor was 6.40 ± 1.06. The leukocyte concentrations of whole blood and PRP were (5.57 ± 1.91) × 1012/L and (32.20 ± 10.42) × 1012/L, respectively, showing significant difference (t=—13.780, P=0.000). The recovery rate of leukocyte was 58.30% ± 19.24%, and the enrichment factor was 6.10 ± 1.93. The concentrations of platelets and leukocyte in PRP were positively correlated with the platelet concentration (r=0.652, P=0.000) and leukocyte concentration (r=0.460, P=0.011) in whole blood. The concentrations of platelet and leukocyte in PRP between male and female were not significantly different (P gt; 0.05). The concentrations of PDGF, TGF-β, and VEGF in PRP were (698.15 ± 64.48), (681.36 ± 65.90), and (1 071.55 ± 106.04) ng/ mL,which were (5.67 ± 1.18), (6.99 ± 0.61), and (5.74 ± 0.83) times higher than those in the whole blood, respectively. PDGF concentration (r=0.832, P=0.020), TGF-β concentration (r=0.835, P=0.019), and VEGF concentration (r=0.824, P=0.023) in PRP were positively correlated with platelet concentration of PRP. Conclusion PRP with high concentrations of platelets, white blood cells and growth factors can be prepared stably by this package.

ObjectiveTo detect the expression of hMLH1, hMSH2 or hMSH6 protein in sporadic colorectal carcinoma (SCRC) and analyze the relationship of its expression to clinicopathologic parameters of patients with SCRC. MethodsTwo hundred and sixty-three patients with SCRC were studied, who underwent surgery in the Department of General Surgery, the Air Force General Hospital; and the Department of Colorectal Surgery, Beijing Cancer Hospital from March 2008 to March 2012. All the patients were diagnosed by histological examination without chemoradiotherapy before operation. Immunohistochemistry was used to detect the hMLH1, hMSH2 or hMSH6 protein expression in the tumor tissues from 263 cases of SCRC. The relationship of its expression to clinicopathologic parameters was analyzed. ResultsThe loss rates of hMLH1, hMSH2, and hMSH6 expressions in the tumor tissues from 263 patients with SCRC were 13.3% (35/263), 12.2% (32/263), and 28.9% (76/263), respectively. The loss rates of hMLH1/hMSH2, hMLH1/ hMSH6, hMSH2/hMSH6, and hMLH1/hMSH2/hMSH6 expressions were 3.4% (9/263), 10.2% (27/263), 6.8% (18/263), and 3.4% (9/263) corresponding. The loss rate of hMLH1 expression in the high differentiated adenocarcinoma tissues was significantly higher than that of the moderate to low differentiated adenocarcinoma or mucous carcinomas tissues (P < 0.01). The loss rate of hMLH2 expression in the tissues of tumor size more than 5 cm was significantly higher than that in the tissues of tumor size less than 5 cm (P < 0.05). The loss rate of hMSH6 expression in the male patient was significantly higher than that of the female patient (P < 0.01) and which in the tumor tissues of less lymph node metastasis was significantly higher than that in the tissues of the more lymph node metastasis (P < 0.01). ConclusionsThe hMLH1, hMSH2, or hMSH6 gene expression deletion is common in SCRC and the relation with the clinical pathology of SCRC is obviously different from Lynch syndrome. Therefore, the effects of hMLH1, hMSH2, and hMSH6 expressions on the development, invasion, and metastasis of SCRC are different from Lynch syndrome too.
Objective To explore surgery strategy of reoperation for type Ⅳa congenital choledochal cyst. Methods The patient was a 20-year-old female with repeated right upper abdominal pain and fever for more than 1 year and aggravation for more than 1 month, and the choledochal cyst excison was performed 15 years ago. The MRI revealed that a huge cyst located in the left lobe of liver, with multiple intrahepatic calculus. The patient was diagnosed with a type Ⅳa congenital choledochal cyst and choledochojejunostomy later and the intrahepatic dilated bile duct was untreated. Results The cystic dilatation of the intrahepatic bile duct was confirmed during the reoperation, and the multiple stones with pus formation were seen, the color of the right liver was normal and the anatomical left hemihepatectomy was performed. The original anastomosis had no stenosis then was preserved. An about 1.5 cm length of extrahepatic bile duct was dissociated from the upper of anastomosis, and the extrahepatic bile duct was cut open and explored with a choledochoscope. The T-tube drainage was performed following removing the stone. The patient recovered well and was discharged smoothly following the surgery. The cholangiography 6 weeks later revealed that the biliary tract was patency and there was no residual stone. There was no jaundice or fever afterwards. Conclusion Complete excision of choledochal cyst and hepaticoduodenostomy is widely accepted as a standard surgery for type Ⅳa congenital choledochal cyst.
