Objective To invesitigate the features of imaging of CT with high resolution (HRCT) in fracture of optic canal, and evaluate the clinical application of HRCT. Methods A total of 22 patients with facture of optic canal underwent thin layer (1.5 mm) CT scanning in axial and coronal positions. The features of the image of fractures of optic canal were analyzed. Results There were 15 cases (68.2%) of fractures in the inner wall, 1 (4.5%) in the lateral wall, 1(4.5%) in the superior wall, 2 (9.1%）in the inferior wall, and 3 (13.6%) were with the compound fracture. The direct sign of the fracture of optic canal was the osseous successional discontinuity of the wall of optic canal, including 5 types: concave (27.3%), lineal(22.7%), comminuted(27.3%), inlaid(9.1%), and mixed (13.6%) type. The indirect signs were hemorrhage of sphenoidal sinus (95.5%),hemorrhage of ethmoid sinus(50%),and optic nerve thickening(36.4%)etc. Conclusions HRCT may clearly exhibit the positions and types of the fracture of optic canal, and it can provide reliable information for the clinical diagnosis and selection of manners of the treatment.

Objective To investigate the expression of oncostatin M (OSM) in patients with sepsis and its role in early recognition of sepsis. Methods Thirty-four patients with sepsis admitted in Shanxi Bethune Hospital fromJune 3, 2021 to January 18, 2022 were selected as a sepsis group, 15 patients with community acquired pneumonia (CAP) as a case control group, and 16 adults who underwent physical examination in the same period were selected as a healthy control group. The patients in the sepsis group were followed up for 28 days and divided into a survival group and a death group. The serum OSM level and its correlation with clinical indexes (white blood cell, neutrophil, lymphocyte, sequential organ failure assessment score and acute physiology and chronic health evaluation Ⅱ) were analyzed, and the diagnostic value of OSM expression level in the early identification of sepsis was analyzed. Results Compared with the case control group and the healthy control group, the expression level of OSM in the sepsis group was significantly higher [(502.07±209.93)pg/mL vs. (368.22±65.95)pg/mL and (382.09±73.04)pg/mL, P<0.05]. However, the high expression of OSM had no significant correlation with white blood cell, neutrophil, lymphocyte or disease severity score (P>0.05), and there was no significant difference in serum OSM level between the sepsis survival group and the death group. Compared with white blood cell count, the high expression of OSM has certain diagnostic value in the early identification of sepsis. The area under the receiver operator characteristic curve of OSM in predicting sepsis was 0.794 (95% confidence interval 0.666 - 0.922, P<0.05), with the sensitivity of 79.4% and the specificity of 73.3%. Conclusion The expression of OSM in patients with sepsis is significantly increased, and the high expression of OSM has a certain diagnostic value in the early identification of sepsis.
Objective To establish a reliable rats model of orthotopic liver transplantation with non-heart beating donors. Methods The model was established with modified double-cuff method. According to obtain pre-liver warm ischemia time experiencing non-heart-beat the rats were divided into 3 groups: 10 min (R10 group), 20 min (R20 group) and 30 min (R30 group), then one week survival after operation was compared in rats. Results The operative time of donor was 30 min approximately except warm ischemia time and the cold preservation time of donor liver was 1 h. The anastomotic time for suprahepatic vena cava was 12-22 min (mean 15 min). The anastomotic time for portal vein and infrahepatic vena cava was about 2 min and 1 min, respectively. The anhepatic phase sustained 14-24 min (mean 19 min). The operative time of receptor was 50-65 min (mean 60 min). Twelve rats died at 24 h after operation, which was considered as operative failure. The success rates of operation in R10 group, R20 group, and R30 group were 95% (19/20), 80% (16/20), and 65% (13/20), respectively. After one week the survival rate was 95% (18/19), 81% (13/16), and 54% (7/13), respectively. Conclusions Improved non-heart donor liver transplantation model of rat on the basis of Kamada’s “twocuff technique” acts as a good simulation in clinical non-heart-donor liver transplantation. This study showes that rat liver can tolerate warm ischemia time less than 30 min, the short-term survival after transplantation can reach satisfactory results. However, long-term survival requires further study.
Objective To establish model of thymectomy in adult rats. Methods The animal models were built by resection of the thymus and simultaneously emptying the air under xiphoid in the rats underwent thoracotomy. Results Of 30 rats, 1 died of postoperative atelectasis, 1 died of excessive bleeding because of puncturing the pulmonary vein by mistake during the operation. Twenty-eight rats survived more than 30 days. A successful rate of 93.3% was achieved in the making of thymectomy model. Conclusion The results show that the model is easy to operate and the success rate is very high, and can be used in the experiment of thymectomy in the rats.
ObjectiveTo evaluate the diagnostic value of monitoring 1,3-beta-D-glucan (G test) in patients with autoimmune disease complicated with invasive fungal disease (IFD). MethodsA retrospective study was performed in hospitalized patients in the First Affiliated Hospital of Zhengzhou Universisty who were diagnosed as autoimmune disease with lung infection during the immunosuppressive therapy between January 2014 and January 2016. A total of 372 patients were enrolled in this study. All subjects were classified according to the 2006 diagnostic criteria and treatment of invasive pulmonaary fungal infection, with serum 1,3-β-D-glucan results not included in the diagnosis. There were 18 cases with proven IFD, 35 cases with probable IFD, and 70 ceses with possible IFD. Fifty-three patients with proven IFD or probable IFD were as a case group, and another 249 patients with no evidence for IFD were as a control group. The value of the G test for diagnosis of automimmune disease with IFD was analyzed by ROC curve. ResultsThe serum 1,3-β-D-glucan level was significantly higher in the case group when compared with the control group [median (interquartile range): 135.0 (63.1 to 319.0) pg/ml vs. 75.9 (41.2 to 88.1) pg/ml, P<0.05]. When the cut-off value of serum 1,3-β-D-glucan level was set at 93.8 pg/ml, the sensitivity, specificity, positive predictive value, and negative predictive value for diagnosis of autoimmune disease with IFD were 0.65 (95% CI 0.56 to 0.73), 0.87 (95% CI 0.83 to 0.92), 0.70 (95% CI 0.64 to 0.81), and 0.83 (95% CI 0.79 to 0.88), respectively. ConclusionThe 1,3-beta-D-glucan test is a valuable method for diagnosis of IFD in patients with autoimmune disease.
Objective To evaluate the efficacy and safety of local triamcinolone combined with conventional interventional therapy in the treatment of benign airway stenosis. Methods PubMed, Cochrane Library, EMbase, Web of science, wanfang, VIP and China National Knowledge Infrastructure were searched by computer between the establishment of the database and August, 2019, and all literatures on the local treatment of benign airway stenosis using triamcinolone combined with conventional interventional therapy were searched. According to inclusion and exclusion criteria, 2 researchers screened the literatures and performed the data extraction and methodological quality evaluation. Meta-analysis was performed with Revman5.2 and Stata software. Results In total, nine randomized controlled trials were included in this meta-analysis, including 449 patients with airway stenosis. The total result showed that in the comparison of short-term efficacy, there were no statistically significant differences in breathability score (SMD=–0.16, 95%CI –0.45 - 0.13, P=0.27), airway diameter (SMD=0.14, 95%CI –0.13 - 0.41, P=0.30), and cross-sectional stenosis rate (SMD=–0.01, 95%CI –0.36 - 0.34, P=0.96) between the treatment group and the control group. In the comparison of long-term efficacy, the breathability score (SMD=–2.53, 95%CI –3.78 - –1.28, P<0.05), airway diameter (SMD=1.31, 95%CI 0.83 - 1.78, P<0.05), cross-sectional stenosis rate (SMD=2.58, 95%CI: 2.11~3.08, P<0.05), and FEV1(SMD=0.42, 95%CI 0.13 - 0.70, P=0.004) of patients in the treatment group were all better than those in the control group. But in terms of adverse reactions, the incidence of bleeding in the airway between two groups was similar (RR=2.00, 95%CI 0.88 - 4.52, P=0.10), other adverse reactions such as blood glucose and plasma cortisol levels were mild, which can be relieved symptomatically. Conclusion Current evidence suggests that topical triamcinolone combined with conventional interventional therapy for benign airway stenosis has a better long-term clinical efficacy with fewer adverse reactions and better overall patient tolerance, which has clinical application value
Objective To summarize the clinical experience of liver retransplantation. Methods Six liver retransplantations were performed. The indications consisted of primary non-function (PNF, 2 cases), acute or chronic rejection (2 cases), stomas stenosis of biliary tract (1 case) and primary sclerosing cholangitis (1 case). The immunosuppressive protocols included tacrolimus, methylprednisolone (MP) and mycophenolate mofetil (MMF). Results Five patients were cured. One patient died on day 4 after liver retransplantation because of multiple organ failure. Postoperative complications included deep fungal infection and wound infection. Conclusions Liver retransplantation is an effective method for graft failure after liver transplantation. Proper indication and optimum operative time, intensive perioperative supervision and proper treatment are very important to improv effect of liver retransplantation.
【Abstract】ObjectiveTo compare the effects of self-designed KYL solution on rat liver preservation with UW solution. Methods Using non-circulated isolated perfused rat liver,SD rat livers were randomly preserved for 0、4、8、16、24 and 48 hours with self-designed KYL solution or UW solution. The effects were assessed by measuring the bile production, the contents of AST， ALT，LDH，free radical（ MDA） and SOD in KrebsHenseleit’s perfusate and the content of intracellar calaium of the rat hepatocytes, and by observing the morphological changes in liver. At the same time, the normal saline was used to preserve the rats liver as negative comparison to know if KYL solution and UW solution can prevent the ischemiareperfusion injury in rat liver transplantation.Results At different periods within 16 hours of preservation,the bile production of the rat livers which were preserved by KYL solution were more than those were preserved by UW solution （P＜0.01）, JP2The contents of AST， ALT and LDH in Krebs-Henseleit’s perfusate were near in UW solution’s. The content of intracellar calaium of the rat hepatocytes which were preserved by KYL solution were less than those were preserved by UW solution （P＜0.01）. In KYL group, the content of MDA was lower than that UW group, the content of SOD was higher than that UW group at 24 and 48 h(P＜0.01). Morphological changes in both groups were almost same. All variables of both groups were better than the rat livers preserved by the normal saline. It was proved that both KYL solution and UW solution could protect the rat livers. Conclusion The study indicated that the effects of self-designed KYL solution on rat liver preservation are similar to that of UW solution. The bile production after reperfusion and the content of intracellar calaium of the rat hepatocytes in KYL group are better than those in UW group .The effect of prevention of rat hepatocellular oedema by self-designed KYL solution are worse than that of UW solution.
【Abstract】Objective To evaluate effect of artificial liver support system (ALSS) in liver failure and liver transplantation.Methods Forty-four patients with liver failure (including 12 undergoing liver transplantation) were treated with MARS or plasma exchange. The changes of toxic substances and cytokines in blood were detected before and after treatment. Results ALSS therapy achieved a remarkable improvement in clinical symptoms and physical signs. After ALSS treatment, there was a significant decrease in total bilirubin, total bile acid, alanine aminotransferase, creatinine, urea nitrogen, blood ammonia and endotoxin levels(P＜0.05); the levels of serum NO, TNF-α, IL-4 and IL-6 were significantly decreased(P＜0.05); there was no statistical change in erythrocytes, leukocytes and platelets. The survival rate of 30 liver failure patients caused by severe hepatitis B was 60.0%(18/30). Six patients with acute liver failure were successfully performed liver transplantation. Two patients in 6 with acute liver failure after liver transplantation survived. One patient in 2 with acute liver failure after pancreatoduodenectomy survived. Conclusion ALSS plays a positive role in treatment of liver failure by removing blood toxins, NO and cytokines. ALSS also plays a substitute role for liver failure patients who are waiting for liver transplantation.
