Objective To explore the normal number of lumbar lateral recess and the relationship between the CT pathology and clinical manifestation in the patients who suffered from lumbar lateral recess stenosis. Methods Lumbar specimen of 15 normal adult corpse and 20 healthy volunteers were observed, and the anterior and posterior(AP) sagittal diameters of normal lumber lateral recess were measured. The CT pathology and clinical manifestation of 174 patients who suffered from lumbar lateral recess stenosis were analysed. Results At the levels of L1 and L2, the lateral recess was found in about 34% normal persons.At the levels of L3 to S1, the lateral recess was found in all healthy persons.All patients who suffered from lumbar lateral recess stenosis had narrow AP sagittal diameters of lumbar lateral recess (

Objective To explore the diagnosis and operative treatment of spinal tumor. Methods Clinical symptom, diagnosis and operative treatment of 22 patients with spinal tumor in our institution from August 1987 to August 2002 were analysed retrospectively. Results Combining with patients' clinical symptoms and results of corresponding examination, all cases were diagnosed before operation. After operation, all the patients recovered with different outcome except 3 patients died. There were 18 cases nearly cured. Conclusion The clinical symptoms of the patients with spinal tumor have some specialty. The preoperative diagnosis mainly depends on MRI. The various operative modes should be taken according to tumor localization.

Objective To evaluate the efficacy and safety of 125I seed implantation combined with transcatheter arterial chemoembolization (TACE) in the treatment of primary hepatocellular carcinoma (PHC).Methods 156 patients who had unresectable PHC seen from January 2012 to December 2015 in our unit were randomly assigned into the study group (76 patients) and the control group (80 patients).The study group of patients were treated with intra-hepatic implantation of 125I seed + TACE,and the control group of patients were treated with three dimensional conformal radiotherapy (3DCRT) + TACE.After ra diotherapy the two groups of patients underwent 2 to 3 times TACE treatment.The biomarker levels were compared between the two groups before and after treatment,and the short-term efficacy,clinical safety and 1 year survival rates were assessed.Results The success rates of the treatment for the two groups were both 100％.Patients in the study group were implanted with 1 016 125I seeds,with an average of (13.7 ± 2.5) seeds per patient.The two groups had no significant difference on short-term efficacy (P ＞ 0.05).The DCR,ORR and 1 year survival rates in the study group were 63.2％,92.1％,55.5％,and they were 61.3％,90.0％,58.1％ in the control group,respectively.There were no significant differences between these 2 groups (P ＞ 0.05).At 1 month after treatment,the two groups had no significant differences onAFP,IGF-Ⅱ and IGFBP-2 [(5.08±0.85) μg/L vs.(5.12 ±0.79) μg/L,(4.77 ±0.58) μg/L vs.(4.86 ±0.53) μg/L,(4.98 ±0.67) μg/L vs.(5.04 ±0.71) μg/L] (P＞0.05).There were no signif-icant differences on chemotherapy drug toxicities between the two groups (P ＞ 0.05).The incidence of radi-ation hepatitis in the study group was 1.3％,while the incidences of radiation dermatitis,hepatitis,gastriculcer in the control group were 5.0％,8.8％,2.5％,respectively.The radiation dermatitis incidence inthe study group was significantly lower than that of the control group (P ＜ 0.05).In the study group,2 pa-tients (2.6％) had their 125I seed slightly moved.Conclusion The short-term efficacy of 125I seed implan-tation plus TACE in the treatment of PHC is no less than the 3DCRT + TACE regimen,but with less radia-tion side effects.

Objective:To compare the preliminary clinical efficacy of iodized oil embolization and improved microspheres injection embolization in patients with hepatic metastasis from gastrointestinal tumors.Methods:In total 100 patients with hepatic metastasis from gastrointestinal tumors were perspective enrolled from July 2015 to July 2017 in the First Affiliated Hospital of Henan University of Science and Technology. The patients were randomly divided into iodized oil group (45 cases) and microspheres group (55 cases) using random number table. The patients in iodized oil group were firstly received regular perfusion chemotherapy, then underwent the embolization with Iodized oil and epirubicin emulsifier. As for the microspheres group, the patients were received epirubicin and microspheres perfusion and embolization alternately after the same regular perfusion chemotherapy. The post-operation complications were observed. The effective rate of tumor controling at each time point was compared between two groups using χ 2 test. Kaplan-Meier method was used to perform the survival analysis. Log-rank test was used to compare the survival rate between two groups. Results:The operation was successfully performed in all the patients, without severe complications found. The follow up time was 18.7±3.4 months. The tumor control rates of 1, 3, 6, 12 and 24 months after operation in the iodine oil group were 71.1% (32/45), 68.9% (31/45), 51.1% (23/45), 28.9% (13/45), 6.7% (3/45) respectively; while in microspheres group were 90.9% (50/55), 89.1% (49/55), 72.7% (40/55), 49.1% (27/55), 23.6% (13/55), respectively. The tumor control rate in microspheres group was superior to that in iodine oil group ( P<0.05). The median lifetime was 12 months and 17 months for iodine oil group and microspheres group respectively, with significant difference (χ2=8.238, P=0.004) found between two groups. As for the microspheres group, the liver abscess was found in one week after operation in 4 patients, who were cured after drainage and anti-inflammatory treatment. Conclusion:The improved microspheres injection embolization is an effective method for the hepatic metastasis from gastrointestinal tumors and superior to iodized oil embolization in tumor controlling, which may prolong the median survival time.

The acyl-CoA synthetase long-chain (ACSL) belongs to an enzyme encoded by a polygenic family. ACSL, located in the endoplasmic reticulum and outer mitochondrial membrane, can catalyze fatty acids to form acyl-CoA, participating in many physiological processes, such as fatty acid metabolism and membrane modification. The ACSL family plays different roles in the fatty acid metabolism of different cells, and its dysfunction can lead to conditions such as fatty liver, arteriosclerosis, and diabetes. As a major subtype of the ACSL family in the liver, ACSL family member 1 (ACSL1) is mainly involved in the maintenance of cholesterol stability, fatty acid activation, and bile acid metabolism. It is also associated with the development of certain liver diseases such as hepatocellular carcinoma and steatosis. This paper reviews differences in physiological functions and functional characteristics of ACSL family members. It also discusses the advances in studies on the role of ACSL1 in influencing lipid metabolism, regulating cellular iron death, and the development of related diseases such as liver fibrosis, hepatocellular carcinoma, cachexia, steatosis, thyroid cancer, and breast cancer.
