Objective Non-alcoholic steatohepatitis(NASH) can progress to liver fibrosis and cirrhosis. Now there are few effective drugs to treat NASH. The aims of this study was to investigate the efficacy of anetholtrithione in the prevention and treatment of NASH in rats induced by high-fat diet. To evaluate the weight,liver index, serum aminotransferase activity and histological features. Methods Sixty SD male rats were divided into six groups. The controlled group(n=10) were fed with normal diet; the NASH model group(n=10)were fed with high-fat diet; the anetholtrithione prevention groups were fed with high-fat diet, and anetholtrithione.The rest rats were fed with high-fat diet, and twelve weeks later they were divided into three groups further. They were anetholtrithione treatment group, diet group and anetholtrithione +diet group. The anetholtrithione treatment group was fed with high-fat diet and anetholtrithione, diet group was fed with normal diet, and anetholtrithione+diet group was fed with normal diet and anetholtrithione. Sixteen weeks later, all rats were sacrificed. Results The anetholtrithione treatment group, diet group and anetholtrithione +diet group had a beneficial effect on lowing weight, liver index, serum aminotransferase activity. A significant improvement in some histological features such as steatosis and inflammation were also observed. Conclusion Anetholtrithione and diet therapy are effective in ameliorating NASH in rats.

Objective To investigate the geometric modeling method for trans-femoral prosthetic socket. Methods The socket reference shapes (i.e. shape templates) were constructed based on the statistic analysis and integrated into the CASD program. The initial socket shape was obtained by transformation from the corresponding reference shape based on the data from the patient's stump and the final socket shape was determined by a kind of three-dimensional interaction method under the OpenGL environment. The fabrication experiment is conducted on the specialized numerical control machine. Results The interactive modification method was easy to use. The machined socket mold is consistent with the designed model in the shape and the precision. Conclusion This method can meet the clinical requirements in the main, but need to optimize the surface shaping characters and rules during the interactive modification stage.

The data of a child with sphingosine phosphate lyase insufficiency syndrome (SPLIS) admitted to Children′s Hospital of Hebei Province on February 4, 2020 were retrospectively analyzed.The child had edema, complicated with ichthyosis, adrenal calcification, and hearing loss from the early infancy.Laboratory examination results suggested a low albumin level, hypercholesterolemia, a high proteinuria level, abnormal liver and renal functions, and hyponatremia.The child gave up treatment and died at home.Whole Exome Sequencing (WES) results showed two hete-rozygous mutations of SGPL1 gene (chr10: 72604336, c.134G>A, p.W45X; chr10: 72629563, c.719G>T, p.S240I). SPLIS is inherited in an autosomal recessive manner.It starts in infancy, and affects the kidney, skin, endocrine, nervous and immune systems.It is suggested that SPLIS patients should take genetic examination.Early diagnosis, appropriate intervention, and vitamin B 6 treatment may relieve some symptoms of SPLIS patients.Adeno-associated virus mediated SGPL1 gene replacement therapy can be a novel cure of SPLIS and is worthy of investigation.

Objective:To analyze and summarize the efficacy and safety of thalidomide in the treatment of refractory systemic juvenile idiopathic arthritis(sJIA).Methods:The clinical data of ten patients with refractory sJIA admitted to Department of Nephrology and Immunology in Children's Hospital of Hebei Province from January 2015 to March 2022 were collected,and the clinical manifestations,efficacy and safety of thalidomide in the treatment of refractory sJIA were analyzed retrospectively. Systemic juvenile arthritis disease activity score(sJADAS)was used to evaluate the efficacy of the treatment. Statistical analysis was performed by repeated measurements using general linear models.Results:Among the 10 children(4 males and 6 females)with refractory sJIA,the average age of onset was(7.5±3.3)years. Seven patients were complicated with macrophage activation syndrome at an early stage of disease.The average course of disease was(4.4±1.7)years,and the longest course of disease was 8.3 years. Before the application of thalidomide,all the 10 children experienced relapses(ranging from 2 to 10 times). The indices of 10 children treated with thalidomide at 6 months and 12 months were compared with those before treatment. Peripheral blood leukocytes[(10.19±3.67)×10 9/L,(8.53±2.83)×10 9/L vs.(16.11±7.81)×10 9/L, F=7.918,11.084, P=0.020,0.009],C-reactive protein[19.13(0.38,35.21)mg/L,8.05(0.10,18.00)mg/L vs. 59.34(24.20,131.90)mg/L, F=7.030,12.731, P=0.026,0.006],sJADAS scores[6.00(1.50,12.50)scores,3.00(0,12.50)scores vs. 20.00(11.50,28.00)scores, F=14.710,17.870, P=0.004,0.002]were decreased significantly. The doses of prednisone[0.13(0,0.45)mg/(kg·d),0.02(0,0.06)mg/(kg·d)vs. 0.42(0.16,1.47)mg/(kg·d), F=5.890,7.623, P=0.041,0.022]were significantly decreased.All the differences were statistically significant. Prednisone was successfully discontinued in 7 cases. Tocilizumab was gradually withdrawn in 3 cases,and tocilizumab administration interval was prolonged in 1 case. None of the 10 children had serious adverse reactions. Conclusion:Thalidomide is clinically effective in the treatment of sJIA,and can reduce the required dose of prednisone and prolong the tocilizumab free remission.
