Objective: The aim of this study was to develop and assess the computer-assisted fabricated individual titanium mesh technique applied for reconstruction of fractured orbital walls to correct post-traumatic enophthalmus and diplopia. Methods: Twenty patients (12 males and 8 females) were inclu-ded in this study. All of patients suffered from unilateral impure orbital fractures. Group A included 8 patients who were reconstructed for the fractured orbit with computer-assisted fabricated titanium mesh technique. Group B had 12 patients treated with traditional methods (titanium meshes in 2, autogenous bone grafts in 7 and Medpor implantation in 3). CT data of group A was input into a image software to rebuild a 3-D orbit and then mirror the unaffected side onto the affected side to replace the demolished orbit. A resin model of the reshaped orbit was then produced and was used to develop custom-fabricated titanium mesh for repair of the fractured orbital wall. The fabricated mesh was used in operation to reconstruct the orbital wall. Treatment was assessed in comparison with traditional way by means of clinical examinations and CT measurements. Results: The difference between pre-operative and post-operative enophthalmos: the mean value of group A was 2.6 mm, group B was 2.0 mm;the difference between the pre-operative and post-operative enlargement volume of traumatic orbit: the mean value of group A was 4.3 mL, group B was 3.7 mL; Index of Medial orbital wall of both groups was 100% and Index of inferior wall reconstruction of group A was 84.7%, group B was 53.3%; The mean depth of implants of group A was 31.2 mm, of group B was 28.3 mm; Improvement of diplopia of group A was 1.5 quadrants, that of group B was 1 quadrant. There were no infection, gaze restriction, or graft extrusion in all patients after operation. Conclusion: Computer-assisted fabricated titanium mesh technique could provide more accurate orbital reconstruction and improve the correction of enophthalmus and diplopia.

Objective To investigate the effects of lanthanum(La)subchronic exposure on the metabolism of calcium(Ca),magnesium(Mg)and iron(Fe)in the liver tissue and serum in rats.Methods 36 Wistar rats were treated with lanthanum chloride(LaCl3)through oral exposure at 0.1,2 and 40 mg/kg respectively.After 90 days of treatment,the rats were sacrificed and the La,Ca,Mg and Fe in the liver tissue were determined,the serum was collected for analysis of Ca,phosphorus(P),Mg,Fe,unsaturated iron-binding capacity(UIBC)and total iron binding capacity(TIBC).Results The La levels in the liver tissue in all LaCl3 exposed dose groups rats were higher obviously than those in the control group(P0.05).Conclusion The result suggests that La subchronic exposure may have some effects on the level and distribution of Ca,Mg and Fe in the liver tissue and serum,which may be a part of its biological effects.

Objective:To investigate the clinical significance of LncRNA anti-differetiation non-coding RNA (ANCR) expression in tumor tissues of gastric cancer patients and its biological effects on cells.Methods:72 cases of gastric cancer tissues and corresponding adjacent tissues were collected from Sep. 2016 to Jun. 2018 in our Hospital. Gastric cancer cell HGC-27 was cultured, lentiviral transfected ANCR cDNA full-length vector was used as a Test group in HGC-27 cells, and transfected blank vector as a control group. Real-time quantitative PCR (qPCR) was used to detect the expression of ANCR, transcription factor Oct4 and Sox2 mRNA in tissues or cells, Western blot was used to detect the expression levels of Oct4 and Sox2 in cells, CCK-8 assay was employed for detecting cell proliferation in both groups, and Transwell invasion and migration assay was used to detect the transfer ability of cells in the two groups.Results:The expressions of ANCR in gastric cancer and corresponding adjacent tissues were respectively 0.013 (0.006, 0.025) and 0.041 (0.011, 0.136) , and the expression of ANCR in gastric cancer tissues was significantly higher than that in adjacent tissues ( P<0.01) , and patients with high expression of ANCR had higher TNM stage and lower cell differentiation ( χ2=7.414 and 8.236, P<0.05) . The expressions of ANCR mRNA in control group and test group were respectively 1.000±0.064 and 6.250±0.889, Oct4 mRNA were respectively 1.000±0.208 and 2.815±0.349, Sox2 mRNA were respectively 1.000±0.173 and 2.526±0.390, Oct4 protein were respectively 1.000±0.148 and 3.396±0.105, Sox2 protein were respectively 1.000±0.119 and 2.916±0.130, and the expressions of ANCR, Oct4 and Sox2 mRNA in the test group were significantly higher than those in the control group ( P<0.01) ; the expression levels of Oct4 and Sox2 protein in the test group were significantly higher than those in the control group. The proliferation abilities of control group and test group were 7.164±0.426 and 9.627±0.605 in 72h, and 13.750±1.089 and 19.166±1.649 in 96h. The proliferation of cells in the Test group at 72 and 96 hours was significantly higher than that in the control group ( P<0.01) . The average number of invasive cells per visual field in control group and test group were 17.26±5.48 and 39.43±5.21, and number of migration cells were 30.49±7.74 and 62.20±7.51, and the number of migration and invasion cells in the Test group was significantly larger than that in the control group ( P<0.01) . Conclusions:The expression of LncRNA ANCR in tumor tissues of gastric cancer patients is significantly increased, and it is closely related to the progression of the disease of patients and the degree of cell malignancy. It can promote the expression of gastric cancer stem cell markers in vitro and enhance the ability of cell proliferation and metastasis.

Objective To explore the surgical treatment and perioperative management of carotid body tumors.Methods Fifteen patients with carotid body tumor were operated upon after appropriate perioperative management.Results Among the 15 cases,6 underwent simple tumor excision,7 had co-resection of carotid body tumor and carotid artery,and 2 cases had arterial anastomosis of common carotid artery and internal carotid artery after co-resection of carotid body tumor.There was no mortality after operation in this series.All patients were followed up from 1 year to 3 years (average,15.3months).Operative incisions healed by primary intention.The pressure symptoms of carotid body tumor disappeared after operation,but two patients had temporary headache for 3months,and one patient died of cerebral infarction.Injury of hypoglossal nerve occurred in one patient but it recovered after treatment.There were no recurrences of carotid body tumor after operation.Conclusions Adequate perioperative management can improve the effect and safety of operation,and decrease operative complications of patients with carotid body tumor.

Objective To explore the optimal timing of liver transplantation for acute liver failure,and analyze relative risk factors affecting patients' prognosis.Methods We retrospectively analyze perioperative clinical data of 50 patients suffering from acute liver failure who underwent liver transplantation between March 2005 and June 2010 in Organ Transplantation Center,the First Affiliated Hospital of Sun Yat-sen University.Patients were divided into survival group and death group.Clinical data before operation were collected and analyzed by univariate and multivariate analysis,respectively.Risk factors influencing the perioperative mortality were selected and were used to direct the operation time.Results There were 50 patients who underwent liver transplantation and 11 cases died during perioperative phase.Five patients died of respiratory infection,three of acute renal failure,one of digestive tract hemorrhage,one of primary allograft failure and one of multiple organ failure.The perioperative,one-year and three-year survival rate were 78％,74％ and 72％ respectively.In the univariate analysis,age,bilirubin level,prothrombin time,creatinine level,grade of encephalopathy and MELD score were found to be significantly different between survival group and death group.The multivariate analysis revealed that age≥65 y,INR ≥3.5,creatinine level ≥ 2.5 mg/dl and MELD score ≥ 40 were independent risk factors affecting survival.Conclusions Liver transplantation is an effective treatment of choice for acute liver failure.Appropriate timing of transplantation helps achieve a high survival rate.
